  1. Metamaterials at the University of Southampton and beyond

    NASA Astrophysics Data System (ADS)

    Zheludev, Nikolay I.

    2017-08-01

    At the University of Southampton, research on metamaterials started in 2000 with a paper describing a metallic microstructure, comprising an ensemble of fully metallic ‘molecules’. In the years since then, metamaterials have evolved from an approach for designing unusual electromagnetic properties by structuring matter at the sub-wavelength scale to become a universal paradigm for active functional media with optical properties on demand at any given point in time and space. Metamaterials are now recognized as a promising enabling technology and one of the most buoyant and exciting research disciplines at the crossroads between photonics and nanoscience. Many ‘made in Southampton’ concepts have influenced the global research community, and we are now working in collaboration with our sister research centre in Nanyang Technological University, Singapore. In this article, I provide a historical overview of the metamaterials research field, from early studies to recent developments through the lens of the Southampton group, and discuss promising future directions.

  2. 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

  10. Biological Oceanography

    NASA Astrophysics Data System (ADS)

    Dyhrman, Sonya

    2004-10-01

    The ocean is arguably the largest habitat on the planet, and it houses an astounding array of life, from microbes to whales. As a testament to this diversity and its importance, the discipline of biological oceanography spans studies of all levels of biological organization, from that of single genes, to organisms, to their population dynamics. Biological oceanography also includes studies on how organisms interact with, and contribute to, essential global processes. Students of biological oceanography are often as comfortable looking at satellite images as they are electron micrographs. This diversity of perspective begins the textbook Biological Oceanography, with cover graphics including a Coastal Zone Color Scanner image representing chlorophyll concentration, an electron micrograph of a dinoflagellate, and a photograph of a copepod. These images instantly capture the reader's attention and illustrate some of the different scales on which budding oceanographers are required to think. Having taught a core graduate course in biological oceanography for many years, Charlie Miller has used his lecture notes as the genesis for this book. The text covers the subject of biological oceanography in a manner that is targeted to introductory graduate students, but it would also be appropriate for advanced undergraduates.

  4. 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

  11. Experiences of professionals providing community care for disabled people in Nagasaki and Southampton.

    2003-09-01

    To report on the factors affecting the resolution of problems experienced by community care professionals and to refine a checklist of methodological issues for future cross-cultural comparative studies. A preliminary comparative study between Japan and the UK. 630 subjects in Nagasaki, Japan and 109 subjects in Southampton, UK who were physically disabled, aged over 40 years, living at home and currently using at least 1 of the community disability care services. Community care professionals from a range of professions were asked about the backgrounds, physical disabilities and needs of their disabled subjects, and the difficulties experienced in providing them with care and rehabilitation services. The proportion of subjects for whom difficulties were experienced in providing services increased with increasing severity of disability in Southampton. By contrast, this trend was less pronounced in Nagasaki where difficulties were reported in approximately 95% of all cases. However, it proved much more difficult to enlist collaboration for this survey in Southampton than in Nagasaki and this led to selection bias in the Southampton sample. The professionals in Nagasaki were hampered by a lack of medical information about their subjects and by a lack of available resources for relieving family members from some of their burden of care. The nature and impact of multidisciplinary team meetings appeared to differ in the 2 countries. It is suggested that the provision of medical information and advice to staff working in community care is a factor of fundamental importance in enabling them to define objectives and to help identify disabled people's care and rehabilitation needs. The means by which such information and advice is shared appeared to differ in the 2 countries. Attenuated resources for community care and poor linkage between care organizations impair the ability of professional staff to resolve problems once they have been identified. It is suggested that each

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 summariesmore » 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.

    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

    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.

    A survey listing 21 major oceanographic concepts and several sub-concepts was mailed to all Ohio earth science teachers. Respondents indicated that most of the oceanography topics taught were geologically-oriented. Oceanography concepts relating to ecology, chemical, physical or life science are considered less important. (DH)

    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

    The appellant charged her employer, the University of Southampton, with sex discrimination in violation of the Equal Pay Act 1970 because she was paid less than men employed in the same position. She had been initially employed at a time when the University was subject to severe financial constraints, and, although she had subsequently been given extra annual pay increases, she was still not paid as much as the men. First the Court of Appeal of England ruled that the financial constraints constituted a "material difference" in circumstances and thus originally justified the difference in salaries under Section 1(3) of the Act. It also held, however, that once those constraints had ended, the justification also ended and the appellant was then entitled to be paid the same wages as men in comparable positions. full text

  13. Macroecology: A Primer for Biological Oceanography

    NASA Astrophysics Data System (ADS)

    Li, W. K. W.

    2016-02-01

    Macroecology is the study of ecological patterns discerned at a spatial, temporal, or organization scale higher than that at which the focal entities interact. Such patterns are statistical or emergent manifestations arising from the ensemble of component entities. Although macroecology is a neologism largely based in terrestrial and avian ecology, macroscopic patterns have long been recognised in biological oceanography. Familiar examples include Redfield elemental stoichiometry, Elton trophic pyramids, Sheldon biomass spectrum, and Margalef life-forms mandala. Macroecological regularities can often be found along various continua, such as along body size in power-law scaling or along habitat temperature in metabolic theory. Uniquely in oceanography, a partition of the world ocean continuum into Longhurst biogeochemical provinces provides a spatial organization well-suited for macroecological investigations. In this rational discrete approach, fundamental processes in physical and biological oceanography that differentiate a set of non-overlapping ocean regions also appear to shape the macroecological structure of phytoplankton communities.

    Operational oceanography requires the quantity, quality, and availability of data set and the timeliness and effectiveness of data products. Without steady and strong operational system supporting, operational oceanography will never be proceeded far. In this paper we describe an integrated platform named Argo Workstation. It operates as a data processing and management system, capable of data collection, automatic data quality control, visualized data check, statistical data search and data service. After it is set up, Argo workstation provides global high quality Argo data to users every day timely and effectively. It has not only played a key role in operational oceanography but also set up an example for operational system.

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

    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

  17. From marine ecology to biological oceanography

    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

    The Sixth Conference on Satellite Meteorology and Oceanography was held in conjunction with the AMS Annual Meeting in Atlanta, Georgia, the week of 6 January 1992. Over 150 scientific papers were presented orally or in poster sessions. Joint sessions were held with the Symposium on Weather Forecasting and the Eighth International Conference on Interactive Information and Processing Systems for Meteorology, Oceanography, and Hydrology. The quality of the papers in the preprint volume, as well as in the presentations at both oral and poster sessions, reflects the robustness of national and international operational and research interests in satellite meteorology and oceanography.more » A preprint volume for this conference is available through the AMS.« less

  20. Connecting Oceanography and Music

    Capturing and retaining the interest of non-science majors in science classes can be difficult, no matter what type of science. At Berklee College of Music, this challenge is especially significant, as all students are music majors. In my Introductory Oceanography course, I use a final project as a way for the students to link class material with their own interests. The students may choose any format to present their projects to the class; however, many students write and perform original music. The performances of ocean-themed music have become a huge draw of the Introductory Oceanography course. In an effort to expand the reach of this music, several colleagues and I organized the first Earth Day event at Berklee, `Earthapalooza 2015.' This event included performances of music originally written for the final projects, as well as other musical performances, poetry readings, guest talks, and information booths. Although the idea of an Earth Day event is not new, this event is unique in that student performances really resonate with the student audience. Additionally, since many of these students will enter professional careers in the performance and recording industries, the potential exists for them to expose large audiences to the issues of oceanography through music. In this presentation, I will play examples of original student compositions and show video of the live student performances. I will also discuss the benefits and challenges of the final projects and the Earth Day event. Finally, I will highlight the future plans to continue ocean-themed music at Berklee.

    Because oceanography is a global science, it clearly benefits from the existence of a world-wide network of oceanographers. As with most STEM disciplines, sub-Saharan Africa is not as well represented in the field of oceanography as it should be, given its large population. The need for oceanographers in sub-Saharan Africa is great, due to a long list of ocean-related issues affecting African development, including but not limited to fishing, oil drilling, sea level rise, coastal erosion, shipping, and piracy. We view this as an opportunity as well as a challenge. Many of the world's fastest growing economies are in sub-Saharan Africa, and STEM capacity building could further fuel this growth. With support from the US National Science Foundation, we ran an oceanography summer school from August 24-27, 2015, at the Regional Maritime University (RMU) in Ghana, West Africa. This first summer school was lecture-based, with a focus on basic chemical oceanography, basic physical oceanography, ocean modeling, and satellite oceanography. About 35 participants came to almost every lecture, and about 20 other participants came to some of the lectures as their time permitted. The participants included RMU faculty, 12 students from the Kwame Nkrumah University of Science and Technology, one Associate Oceanographer from the University of Ghana, and some participants from private sector companies and Ghanaian governmental agencies. There were long and lively discussions at the end of each lecture, and there was a lengthy discussion at the conclusion of the school on how to improve future summer schools. In 2016 and 2017, we plan to divide into smaller groups so that participants can pursue their particular interests in greater depth, and to allow time for student presentations. We also plan to begin exploring the potential for research partnerships, and to utilize distance learning to involve more faculty and students from locations throughout Ghana and perhaps from even other

  3. 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.

  5. Developing Online Oceanography at UCSB

    Oceanography at UCSB is an introductory general education science course taken by up to 200 students per quarter. The emphasis is on learning science process by engaging in authentic science activities that use real earth data. Recently, to increase student motivation, the course has been modified to include an Earth Summit framework. The online support being developed for this course is the first step in the creation of a completely online oceanography class. Foundation software was first tested in the class during Spring 2001. Online activities that are supported are writing and instructor feedback, online threaded discussion with live chat and graphics, automatically graded homeworks and games, auto graded quizzes with questions randomly selected from a database, and thought problems graded by the instructor(s). Future plans include integration with commercial course management software. To allow choice of assignments, all course activities totaled110%. Since grades were based on A=90-100, B=80-90, C= 70-80, etc, it was possible to get a better than A grade. Students see the effect (on their grade) of each assignment by calculating their current course grade. Course activities included (most of which are automatically graded): weekly lab homeworks, weekly mini-quizzes (10 multiple choice questions selected at random from a topic database), weekly thought questions (graded by the TA), 3 written assignments, and "Question of the Day" from lecture (credit given for handing it in), The online writing software allowed students to enter their writing, edit and link to graphic images, print the paper, and electronically hand it in. This has the enormous advantage of allowing the instructor and TA's convenient access to all student papers. At the end of the course, students were asked how effective each of the course activities were in learning the course material. On a five point scale, ranging from highest contribution to lowest, the percentage of students giving

    In this talk I will review some of Jule Charney's impacts on current oceanographic research. He was of course a major seminal figure in geophysical fluid dynamics, an approach to understanding the atmosphere and oceans that has been thoroughly absorbed in contemporary thinking. In oceanography, his publications make vorticity dynamics the centerpiece of his analysis. Here I pursue two other aspects of his work. The first is to note that his 1955 paper "The Gulf Stream as an inertial boundary layer" appears to be the earliest numerical model in oceanography. The second is that his work on the equatorial undercurrent leads to a simplification of equatorial ocean structure that was exploited by Zebiak and Cane in their model for ENSO, and thus structures later views of how equatorial ocean dynamics influence sea surface temperature.

    Smart, sustainable and inclusive Blue Growth means also knowing past technology and the paths followed by ancients in order to understand and monitor marine environments. In general, history of Science is a matter that is not enough explored and explained or promoted in high schools or university official programmes, and, usually, scientist do not consider it as an important part of their curricula. However, bad or good ideas, abandoned or forgotten beliefs, concepts, opinions, do still have a great potential for inspiring present and future scientists, no matter in which historical period they may have been formulated: they should be always be taken into consideration, critically examined and observed by a very close point of view, not just as part of the intellectual framework of some obsolete 'Cabinet of Curiosities' with limited access except for the chosen few. Moreover, history of Science should be transmitted in a more practical way, with hands-on labs showing the limits and challenges that prior generations of ocean explorers, investigators and seafarers had to face in order to answer to crucial questions as self-orientation in open sea, understanding main currents and waves, predicting meteorological conditions for a safe navigation. Oceanography is a relatively young branch of science, and still needs further approvals and knowledge (National Science Foundation, 2000). The Scientific Dissemination Group (SDG) "La Spezia Gulf of Science" - made up by Research Centres, Schools and Cultural associations located in La Spezia (Liguria, Italy) - has a decadal experience in initiatives aimed at people and groups of people of all ages, who are keen on science or who can be guided in any case to take an interest in scientific matters (Locritani et al., 2015).

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.

We cover our research on aspects of the representation of chemical information in the context of the world wide web (WWW) and its semantic enhancement (the Semantic Web) and illustrate this with the example of the representation of quantities and units within the Semantic Web. We explore the changing nature of laboratories as computing power becomes increasing powerful and pervasive and specifically look at the function and role of electronic or digital notebooks. Having focussed on the creation of chemical data and information in context, we finish the paper by following the use and reuse of this data as facilitated by the features provided by digital repositories and their importance in facilitating the exchange of chemical information touching on the issues of open and or intelligent access to the data. © 2015 The Authors.

  9. Utilizing social media for informal ocean conservation and education: The BioOceanography Project

    NASA Astrophysics Data System (ADS)

    Payette, J.

    2016-02-01

    Science communication through the use of social media is a rapidly evolving and growing pursuit in academic and scientific circles. Online tools and social media are being used in not only scientific communication but also scientific publication, education, and outreach. Standards and usage of social media as well as other online tools for communication, networking, outreach, and publication are always in development. Caution and a conservative attitude towards these novel "Science 2.0" tools is understandable because of their rapidly changing nature and the lack of professional standards for using them. However there are some key benefits and unique ways social media, online systems, and other Open or Open Source technologies, software, and "Science 2.0" tools can be utilized for academic purposes such as education and outreach. Diverse efforts for ocean conservation and education will continue to utilize social media for a variety of purposes. The BioOceanography project is an informal communication, education, outreach, and conservation initiative created for enhancing knowledge related to Oceanography and Marine Science with an unbiased yet conservation-minded approach and in an Open Source format. The BioOceanography project is ongoing and still evolving, but has already contributed to ocean education and conservation communication in key ways through a concerted web presence since 2013, including a curated Twitter account @_Oceanography and BioOceanography blog style website. Social media tools like those used in this project, if used properly can be highly effective and valuable for encouraging students, networking with researchers, and educating the general public in Oceanography.

  13. 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.

  15. An Earth Summit in a Large General Education Oceanography Class

    NASA Astrophysics Data System (ADS)

    Dodson, H.; Prothero, W. A.

    2001-12-01

    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

    2017-01-01

    A study published in 2007 showed that the intake of six food colours (the so-called 'Southampton colours') may have an adverse effect on activity and attention in children. The present study set out to assess the exposure of Polish children (3 and 8-9 years old, n = 149) to six of the target colours. Two methods were used to evaluate colour consumption by children: scenario 1 using the maximum permitted levels (MPLs) and actual food consumption data; and scenario 2 using the actual levels in food and actual food consumption data. The data on the actual consumption of food containing the colours was collected using a 7-day questionnaire survey. The results of laboratory analysis of food consumed by children provided data on the actual levels of the colours in food. Consumption of the colours estimated by scenario 1 in any case did not exceed the acceptable daily intakes (ADIs) of the colours in both age groups of children. For more refined colour intake (scenario 2), isolated cases exceeding the ADI were recorded for four colours, but assuming that manufacturers comply with the current legislation on MPL of colours in food, the intake of the colours assessed in scenario 2 should not be a reason for exceeding of ADIs for the target food colours.

    Tello, Olvido; Gómez, María; González, Sonsoles

    2016-04-01

    Since 1914, the Spanish Institute of Oceanography (IEO) performs multidisciplinary studies of the marine environment. In same case are systematic studies and in others are specific studies for special requirements (El Hierro submarine volcanic episode, spill Prestige, others.). Different methodologies and data acquisition techniques are used depending on studies aims. The acquired data are stored and presented in different formats. The information is organized into different databases according to the subject and the variables represented (geology, fisheries, aquaculture, pollution, habitats, etc.). Related to physical and chemical oceanography data, in 1964 was created the DATA CENTER of IEO (CEDO), in order to organize the data about physical and chemical variables, to standardize this information and to serve the international data network SeaDataNet. www.seadatanet.org. This database integrates data about temperature, salinity, nutrients, and tidal data. CEDO allows consult and download the data. http://indamar.ieo.es On the other hand, related to data about marine species in 1999 was developed SIRENO DATABASE. All data about species collected in oceanographic surveys carried out by researches of IEO, and data from observers on fishing vessels are incorporated in SIRENO database. In this database is stored catch data, biomass, abundance, etc. This system is based on architecture ORACLE. Due to the large amount of information collected over the 100 years of IEO history, there is a clear need to organize, standardize, integrate and relate the different databases and information, and to provide interoperability and access to the information. Consequently, in 2000 it emerged the first initiative to organize the IEO spatial information in an Oceanography Information System, based on a Geographical Information System (GIS). The GIS was consolidated as IEO institutional GIS and was created the Spatial Data Infrastructure of IEO (IDEO) following trend of INSPIRE. All

    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.

  15. Physical oceanography of continental shelves

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

    Allen, J.S.; Beardlsey, R.C.; Blanton, J.O.

    Knowledge of the physical oceanography of continental shelves has increased tremendously in recent years, primarily as a result of new current and hydrographic measurements made in locations where no comparable measurements existed previously. In general, observations from geographically distinct continental shelves have shown that the nature of the flow may vary considerably from region to region. Although some characteristics, such as the response of currents to wind forcing, are common to many shelves, the relative importance of various physical processes in influencing the shelf flow field frequently is different. In the last several years, the scientific literature on shelf studiesmore » has expanded rapidly, with that for separate regions, to some extent, developing independently because of the variable role played by different physical effects. Consequently, it seems that a simultaneous review of progress in physical oceanographic research in different shelf regions would be especially useful at this time in order to help assess the overall progress in the field. This multi-author report has been compiled as a result. Included are sections on the physical oceanography of continental shelves, in or off of, the eastern Bering Sea, northern Gulf of Alaska, Pacific Northwest, southern California, west Florida, southeastern US, Middle Atlantic Bight, Georges Bank and Peru. These discussions clearly point to the diverse nature of the dominant physics in several of the regions, as well as to some of the dynamical features they share in common. 390 references, 23 figures.« less

    The global ocean is an integrated living system where energy and matter transformations are governed by interdependent physical, chemical and biotic processes. Although the fundamentals of ocean physics and chemistry are well established, comprehensive approaches to describing and interpreting oceanic microbial diversity and processes are only now emerging. In particular, the application of genomics to problems in microbial oceanography is significantly expanding our understanding of marine microbial evolution, metabolism and ecology. Integration of these new genome-enabled insights into the broader framework of ocean science represents one of the great contemporary challenges for microbial oceanographers.

    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.

    2004-12-01

    The Products and Services (P&S) department in the Space Oceanography Division at CLS is in charge of diffusing and promoting altimetry and operational oceanography data. P&S is so involved in Aviso satellite altimetry project, in Mercator ocean operational forecasting system, and in the European Godae /Mersea ocean portal. Aiming to a standardisation and a common vision and management of all these ocean data, these projects led to the implementation of several OPeNDAP/LAS Internet servers. OPeNDAP allows the user to extract via a client software (like IDL, Matlab or Ferret) the data he is interested in and only this data, avoiding him to download full information files. OPeNDAP allows to extract a geographic area, a period time, an oceanic variable, and an output format. LAS is an OPeNDAP data access web server whose special feature consists in the facility for unify in a single vision the access to multiple types of data from distributed data sources. The LAS can make requests to different remote OPeNDAP servers. This enables to make comparisons or statistics upon several different data types. Aviso is the CNES/CLS service which distributes altimetry products since 1993. The Aviso LAS distributes several Ssalto/Duacs altimetry products such as delayed and near-real time mean sea level anomaly, absolute dynamic topography, absolute geostrophic velocities, gridded significant wave height and gridded wind speed modulus. Mercator-Ocean is a French operational oceanography centre which distributes its products by several means among them LAS/OPeNDAP servers as part of Mercator Mersea-strand1 contribution. 3D ocean description (temperature, salinity, current and other oceanic variables) of the North Atlantic and Mediterranean are real-time available and weekly updated.

    Copernicus, previously known as GMES (Global Monitoring for Environment and Security), is the European Programme for the establishment of a European capacity for Earth Observation and Monitoring. Copernicus aims to provide a sustainable service for Ocean Monitoring and Forecasting validated and commissioned by users. From May 2015, the Copernicus Marine Environment Monitoring Service (CMEMS) is working on an operational mode through a contract with services engagement (result is regular data provision). Within CMEMS, the In Situ Thematic Assembly Centre (INSTAC) distributed service integrates in situ data from different sources for operational oceanography needs. CMEMS INSTAC is collecting and carrying out quality control in a homogeneous manner on data from providers outside Copernicus (national and international networks), to fit the needs of internal and external users. CMEMS INSTAC has been organized in 7 regional Dissemination Units (DUs) to rely on the EuroGOOS ROOSes. Each DU aggregates data and metadata provided by a series of Production Units (PUs) acting as an interface for providers. Homogeneity and standardization are key features to ensure coherent and efficient service. All DUs provide data in the OceanSITES NetCDF format 1.2 (based on NetCDF 3.6), which is CF compliant, relies on SeaDataNet vocabularies and is able to handle profile and time-series measurements. All the products, both near real-time (NRT) and multi-year (REP), are available online for every CMEMS registered user through an FTP service. On top of the FTP service, INSTAC products are available through Oceanotron, an open-source data server dedicated to marine observations dissemination. It provides services such as aggregation on spatio-temporal coordinates and observed parameters, and subsetting on observed parameters and metadata. The accuracy of the data is checked on various levels. Quality control procedures are applied for the validity of the data and correctness tests for the

    Cane, M. A.; Sarachik, E. S.

    1983-01-01

    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.

    Recovering 3D scenes from 2D images is an under-constrained task; optimal estimation depends upon knowledge of the underlying scene statistics. Here we introduce the Southampton-York Natural Scenes dataset (SYNS: https://syns.soton.ac.uk), which provides comprehensive scene statistics useful for understanding biological vision and for improving machine vision systems. In order to capture the diversity of environments that humans encounter, scenes were surveyed at random locations within 25 indoor and outdoor categories. Each survey includes (i) spherical LiDAR range data (ii) high-dynamic range spherical imagery and (iii) a panorama of stereo image pairs. We envisage many uses for the dataset and present one example: an analysis of surface attitude statistics, conditioned on scene category and viewing elevation. Surface normals were estimated using a novel adaptive scale selection algorithm. Across categories, surface attitude below the horizon is dominated by the ground plane (0° tilt). Near the horizon, probability density is elevated at 90°/270° tilt due to vertical surfaces (trees, walls). Above the horizon, probability density is elevated near 0° slant due to overhead structure such as ceilings and leaf canopies. These structural regularities represent potentially useful prior assumptions for human and machine observers, and may predict human biases in perceived surface attitude. PMID:27782103

    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

    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.

    Lifestyle and health behaviours are strongly linked to non-communicable disease risk, but modifying them is challenging. There is an increasing recognition that adolescence is an important time for lifestyle and health behaviours to become embedded. Improving these behaviours in adolescents is important not only for their own health but also for that of their future children. LifeLab Southampton has been developed as a purpose-built classroom and laboratory in University Hospital Southampton. Secondary school students visit LifeLab to learn how childhood, adolescent and parental nutrition influences health, understand the impact of their lifestyle on their cardiovascular and metabolic health, and to inspire them with the excitement of research and future career possibilities in science. The LifeLab visit is part of a programme of work linked to the English National Curriculum. Pilot work has indicated that attitudes towards health can be changed by such LifeLab sessions. A cluster randomised controlled trial is being conducted to evaluate the effectiveness of the LifeLab intervention, the primary outcome being a measurement of the change in nutrition, health and lifestyle literacy from before to after the LifeLab intervention. The LifeLab intervention comprises professional development for the teachers involved; preparatory lessons for the school students, delivered in school; a hands-on practical day at LifeLab, including a 'Meet the Scientist' session; post-visit lessons delivered in school; and the opportunity to participate in the annual LifeLab Schools' Conference. This study aims to recruit approximately 2,500 secondary school students aged 13 to 14 years from 32 schools (the clusters) from Southampton and neighbouring areas. Participating schools will be randomised to control or intervention groups. The intervention will be run over two academic school years, with baseline questionnaire data collected from students at participating schools at the start of

    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.

  5. Developments in Airborne Oceanography and Air-Sea Interaction

    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

    Chlamydia trachomatis is the most common sexually transmitted infection (STI) in England. Our objective was to perform a detailed survey of the molecular epidemiology of C. trachomatis in the population of Southampton UK attending the genitourinary medicine clinic (GUM) to seek evidence of sexual network activity. Our hypothesis was that certain genotypes can be associated with specific demographic determinants. 380 positive samples were collected from 375 C. trachomatis positive GUM attendees out of the 3118 who consented to be part of the survey. 302 of the positive samples were fully genotyped. All six of the predominant genotypes possessed ompA locus type E. One ward of Southampton known to contain a large proportion of students had a different profile of genotypes compared to other areas of the city. Some genotypes appeared embedded in the city population whilst others appeared transient. Predominant circulating genotypes remain stable within a city population whereas others are sporadic. Sexual networks could be inferred but not conclusively identified using the data from this survey.

    The British Lung Foundation highlighted Southampton City as a hotspot for patients at future risk of chronic obstructive pulmonary disease (COPD) exacerbations due to severe deprivation levels and a high undiagnosed level of disease based on health economic modelling. We developed a strategy spanning primary and secondary care to reduce emergency admissions of patients with acute exacerbations of COPD and increase the diagnosed prevalence of COPD on general practitioner (GP) registers closer to that predicted from local modelling. A comprehensive 3-year audit of admissions was performed. Patients who had been admitted with an exacerbation to University Hospital Southampton three or more times in the previous 12 months were cohorted and cared for in a consultant-led, but community based, COPD service. Within primary care, a programme of education and case-based finding was delivered to most practices within the city. Thirty-four patients were found to be responsible for 176 admissions (22% of total COPD admissions) to the hospital. These 34 patients required 185 active interventions during the 12-month period but only 39 hospital admissions. The 30-day readmission rate dropped from 13.4 to 1.9% (P<0.01), confirming the contribution the cohort made to readmissions. Prior to the project, the registered Quality Outcomes Framework prevalence of COPD within the city was 1.5; after just 1 year of the project, the prevalence increased from 1.5 to 2.27%. The use of medical intelligence to investigate the underlying processes of COPD hospital admissions led to an effective intervention delivered in a consultant-led model.

  9. Coupling biology and oceanography in models.

    PubMed

    Fennel, W; Neumann, T

    2001-08-01

    The dynamics of marine ecosystems, i.e. the changes of observable chemical-biological quantities in space and time, are driven by biological and physical processes. Predictions of future developments of marine systems need a theoretical framework, i.e. models, solidly based on research and understanding of the different processes involved. The natural way to describe marine systems theoretically seems to be the embedding of chemical-biological models into circulation models. However, while circulation models are relatively advanced the quantitative theoretical description of chemical-biological processes lags behind. This paper discusses some of the approaches and problems in the development of consistent theories and indicates the beneficial potential of the coupling of marine biology and oceanography in models.

    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.

    Life on Earth most likely originated as microorganisms in the sea. Over the past approximately 3.5 billion years, microorganisms have shaped and defined Earth's biosphere and have created conditions that have allowed the evolution of macroorganisms and complex biological communities, including human societies. Recent advances in technology have highlighted the vast and previously unknown genetic information that is contained in extant marine microorganisms, from new protein families to novel metabolic processes. Now there is a unique opportunity, using recent advances in molecular ecology, metagenomics, remote sensing of microorganisms and ecological modelling, to achieve a comprehensive understanding of marine microorganisms and their susceptibility to environmental variability and climate change. Contemporary microbial oceanography is truly a sea of opportunity and excitement.

    The Southampton No 1 (Western Esplanade) geothermal well which was drilled for the development of hot brines in the Triassic sandstones was tested. The aquifer was intersected at a depth of 1729 m. The upper 24 m contained thin, medium to coarse grained sandstones which are the main water bearing horizons. The static water level is about 80 m below ground level. Gas lifting with nitrogen indicate that the sandstones contain a brine with a salinity of 125 g/l at a temperature of 76 deg C. The maximum yield of the well was 30 l/s for a pressure reduction of 4.2 MN/sq m. The transmissivity of the aquifer is about 5 Dm. A hydraulic barrier, probably a fault, occurs close to the well.

    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.

    Coastal environments are a key location for transport, commercial, residential and defence infrastructure, and have provided conditions suitable for economic growth. They also fulfil important cultural, recreational and aesthetic needs; have intrinsic ecosystem service values; and provide essential biogeochemical functions such as primary productivity, nutrient cycling and water filtration. The rapid expansion in economic development and anticipated growth of the population in the coastal zones along the Yellow and East China Sea basin has placed this region under intense multiple stresses. Here we aim to: 1) synthesize the new knowledge/science in coastal oceanography since 2010 within the context of the scientific literature published in English; 2) report on a citation analysis that assesses whether new research topics have emerged and integrated over time, indicate the location of modelling and field-based studies; and 3) suggest where the new research should develop for heavily impacted estuaries and coastal seas of East Asia. The conclusions of the synthesis include: 1) China has emerged as a dominant force in the region in producing scientific literature in coastal oceanography, although the area of publications has shifted from its traditional fields such as physical oceanography; 2) there has been an increasing number of publications with cross-disciplinary themes between physical oceanography and other fields of the biological, chemical, and geological disciplines, but vigorous and systematic funding mechanisms are still lacking to ensure the viability of large scale multi-disciplinary teams and projects in order to support trans-disciplinary research and newly emerging fields; 3) coastal oceanography is responding to new challenges, with many papers studying the impacts of human activities on marine environment and ecology, but so far very few studying management and conservation strategies or offering policy solutions.

    In the early 1980s, Germany started a new era of modern Antarctic research. The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) was founded and important research platforms such as the German permanent station in Antarctica, today called Neumayer III, and the research icebreaker Polarstern were installed. The research primarily focused on the Atlantic sector of the Southern Ocean. In parallel, the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) started a priority program `Antarctic Research' (since 2003 called SPP-1158) to foster and intensify the cooperation between scientists from different German universities and the AWI as well as other institutes involved in polar research. Here, we review the main findings in meteorology and oceanography of the last decade, funded by the priority program. The paper presents field observations and modelling efforts, extending from the stratosphere to the deep ocean. The research spans a large range of temporal and spatial scales, including the interaction of both climate components. In particular, radiative processes, the interaction of the changing ozone layer with large-scale atmospheric circulations, and changes in the sea ice cover are discussed. Climate and weather forecast models provide an insight into the water cycle and the climate change signals associated with synoptic cyclones. Investigations of the atmospheric boundary layer focus on the interaction between atmosphere, sea ice and ocean in the vicinity of polynyas and leads. The chapters dedicated to polar oceanography review the interaction between the ocean and ice shelves with regard to the freshwater input and discuss the changes in water mass characteristics, ventilation and formation rates, crucial for the deepest limb of the global, climate-relevant meridional overturning circulation. They also highlight the associated storage of anthropogenic carbon as well as the cycling of carbon, nutrients and trace metals

    Several Thule forager groups settled successfully in the Hudson Bay region of the Canadian Arctic starting at ca. AD 1050. First evidence of settlements at Native Point on Southampton Island dates prior to AD 1400 by Sadlermiuts. The village consisted of numerous sod and winter houses which framed a small shallow freshwater body (ca. 20,000 m2). Numerous butchered carcasses of mainly walrus, seal, bowhead whales and caribou remained in the pond and further decayed in the water. Here, we present first results from three short sediment cores taken from the bottom of the settlement pond. Sedimentological, geochemical and micropaleontological analyses show an abrupt change at ca. AD 1500 from pristine aquatic environments to eutrophic conditions. Variation in d15N and d13C of the organic matter suggest that this shift is related to the first butchering activity of Sadlermiuts in the area.

    To investigate risks of physical activity at work by pregnancy trimester, including the effects on head and abdominal circumference. At 34 weeks of gestation we interviewed 1327 mothers from the prospective Southampton Women's Survey (SWS); we asked about their activities (working hours, standing/walking, kneeling/squatting, trunk bending, lifting and night shifts) in jobs held at each of 11, 19 and 34 weeks of gestation, and subsequently ascertained four birth outcomes (preterm delivery, small for gestational age (SGA) and reduced head or abdominal circumference) blinded to employment history. Risk of preterm delivery was elevated nearly threefold in women whose work at 34 weeks entailed trunk bending for >1 h/day. Small head circumference was more common in babies born to women who worked for >40 h/week. However, no statistically significant associations were found with SGA or small abdominal circumference, and preterm delivery showed little association with long working hours, lifting, standing or shift work. There is a need for more research on trunk bending late in pregnancy, and on the relationship of work to reduced head circumference. Our findings on several other occupational exposures common among pregnant workers are reassuring.

  9. 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.

    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

    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 (OO). Some systems like the tide gauges network has been working for more than 70 years. The IEO 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 IEO Observing System (IEOOS) includes 6 permanent moorings equipped with currentmeters, an open-sea ocean-meteorological buoy offshore Santander and an SST satellital image reception station. It also supports the Spanish contribution to the ARGO international program with 47 deployed profilers, and continuous monitoring thermosalinometers, meteorological stations and ADCP onboard the IEO research vessels. The system is completed with the IEO contribution to the RAIA 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 as navigation, resource management, risks management, recreation, etc, 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 programs Earth observation sponsored by the United Nations or the European Union. The synchronic observation system permits following spatio-temporal description of some events, 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.

    Overexploitation and climate change are increasingly causing unanticipated changes in marine ecosystems, such as higher variability in fish recruitment and shifts in species dominance. An ecosystem-based approach to fisheries attempts to address these effects by integrating populations, food webs and fish habitats at different scales. Ecosystem models represent indispensable tools to achieve this objective. However, a balanced research strategy is needed to avoid overly complex models. Ecosystem oceanography represents such a balanced strategy that relates ecosystem components and their interactions to climate change and exploitation. It aims at developing realistic and robust models at different levels of organisation and addressing specific questions in a global change context while systematically exploring the ever-increasing amount of biological and environmental data.

    2017-12-01

    Geoscience classrooms have benefitted greatly from the use of interactive, dry-erasable globes to supplement instruction on topics that require three-dimensional visualization, such as seismic wave propagation and the large-scale movements of tectonic plates. Indeed, research by Bamford (2013) demonstrates that using three-dimensional visualization to illustrate complex processes enhances student comprehension. While some geoscience courses tend to bake-in lessons on visualization, other disciplines of earth science that require three-dimensional visualization, such as oceanography, tend to rely on students' prior spatial abilities. In addition to spatial intelligence, education on the three-dimensional structure of the ocean requires knowledge of the external processes govern the behavior of the ocean, as well as the vertical and lateral distribution of water properties around the globe. Presented here are two oceanographic activities that utilize RealWorldGlobes' dry-erase globes to supplement traditional oceanography lessons on thermohaline and surface ocean circulation. While simultaneously promoting basic plotting techniques, mathematical calculations, and unit conversions, these activities touch on the processes that govern global ocean circulation, the principles of radiocarbon dating, and the various patterns exhibited by surface ocean currents. These activities challenge students to recognize inherent patterns within their data and synthesize explanations for their occurrence. Spatial visualization and critical thinking are integral to any geoscience education, and the combination of these abilities with engaging hands-on activities has the potential to greatly enhance oceanography education in both secondary and postsecondary settings

    This session will present educational activities developed for an introductory Oceanography lecture and laboratory class by NOAA Teacher-at-Sea Jacquelyn Hams following participation in Leg 3 of Project DYNAMO (Dynamics of the Madden-Julian Oscillation) in November-December 2011. The Madden-Julian Oscillation (MJO) is an important tropical weather phenomenon with origins in the Indian Ocean that impacts many other global climate patterns such as the El Nino Southern Oscillation (ENSO), Northern Hemisphere monsoons, tropical storm development, and pineapple express events. The educational activities presented include a series of lessons based on the observational data collected during Project DYNAMO which include atmospheric conditions, wind speeds and direction, surface energy flux, and upper ocean turbulence and mixing. The lessons can be incorporated into any introductory Oceanography class discussion on ocean properties such as conductivity, temperature, and density, ocean circulation, and layers of the atmosphere. A variety of hands-on lessons will be presented ranging from short activities used to complement a lecture to complete laboratory exercises.

    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

  7. Is the Oceanography of the New Zealand Subantarctic Region Responding to the Tropics?

    NASA Astrophysics Data System (ADS)

    2016-02-01

    The Campbell Plateau, south of New Zealand plays an important role in New Zealand's regional climate and its oceanography may have a significant impact on fluctuations in fish stocks and marine mammal populations. It is located between the Subtropical and Subantarctic Fronts and exhibits marked variability over long time scales. It has been previously assumed, because of its location, that the Campbell Plateau oceanography is driven by Subantarctic and polar processes. Recent analysis, presented here, suggests this in not the case, and instead forcing comes from the tropics and subtropics. This is supported by positive correlations of Sea Level Anomalies (SLA) and Sea Surface Temperature (SST) with the Southern Oscillation Index (SOI) with SOI leading changes on the Campbell Plateau by two months for SLA and seven months for SST. Here we will present evidence of the similarity between the Campbell Plateau and the Tasman Sea SLA trends which suggests a closer relationship with the subtropical region. Satellite collected SLA data and SST from the last two decades are investigated to understand trends and long-term variability over the Campbell Plateau and its relationship with the surrounding open ocean, and other potential remote drivers of variability.

    In the context of undergraduate education in oceanography, we are constantly striving for innovative ways to enhance student learning and enthusiasm for marine science. Community engagement is a form of experiential education that not only promotes a better understanding of concepts among undergraduate students but also allows them to interact with the community in a way that is mutually beneficial to both parties. Here I present on my experience in incorporating a community engagement project in my undergraduate physical oceanography course at the University of San Diego (USD) in collaboration with Mission Bay High School (MBHS), a local Title 1 International Baccalaureate high school with a high proportion of low-income students and students from underrepresented groups in STEM. As part of this project, the undergraduate students from my physical oceanography course were challenged to develop interactive workshops to present to the high school students at MBHS on some topic in oceanography. Prior to the workshops, the USD students met with the high school students at MBHS during an introductory meeting in which they could learn about each other's interests and backgrounds. The USD students then worked in teams of three to design a workshop proposal in which they outlined their plan for a workshop that was interactive and engaging, relying on demonstrations and activities rather than lecture. Each of the three teams then presented their workshops on separate days in the Mission Bay High School classroom. Finally, the USD students met again with the high school students at MBHS for a conclusion day in which both sets of students could discuss their experiences with the community engagement project. Through the workshop itself and a reflection essay written afterwards, the USD students learned to approach concepts in oceanography from a different perspective, and think about how student backgrounds can inform teaching these concepts.

    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

    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.

    Geoscience education is key for the understanding of our home, the planet Earth. The Lagos Ciência Viva Science Centre (CCVL) in Portugal develops various geoscience activities including astronomy sessions, geology, paleontology and oceanography field trips, complementary primary school classes, seminars and numerous workshops for a public ranging from pre-schoolers to seniors . Our experience in geoscience communication and informal education also includes a formal partnership with a research centre from the University of the Algarve, the CIMA - Centre for Marine and Environmental Research, through the project MOSES, which focuses on sand transport along crenulated coasts. Based on the project goals, methods and results, the CCVL team designed a communication and outreach plan including a seminar, a field trip and a workshop, to alert for the subjects of coastal erosion and management, both highly relevant in the Algarve. This partnership was highly beneficial for both parts as it facilitated the communication of a scientific project to the public, while the CCVL had the opportunity to update and expand its educational offer. This type of interaction between universities/research institutes and science centres/museums allows scientists to focus on their research work, reducing their need to invest in communication, and provides good and updated scientific contents to science communicators, ensuring a direct channel between scientific research and the public.

    2014-05-01

    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.

  15. 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

    The questions that chemical oceanographers prioritize over the coming decades, and the methods we use to address these questions, will define our field's contribution to 21st century science. In recognition of this, the U.S. National Science Foundation and National Oceanic and Atmospheric Administration galvanized a community effort (the Chemical Oceanography MEeting: A BOttom-up Approach to Research Directions, or COME ABOARD) to synthesize bottom-up perspectives on selected areas of research in Chemical Oceanography. Representing only a small subset of the community, COME ABOARD participants did not attempt to identify targeted research directions for the field. Instead, we focused on how best to foster diverse research in Chemical Oceanography, placing emphasis on the following themes: strengthening our core chemical skillset; expanding our tools through collaboration with chemists, engineers, and computer scientists; considering new roles for large programs; enhancing interface research through interdisciplinary collaboration; and expanding ocean literacy by engaging with the public. For each theme, COME ABOARD participants reflected on the present state of Chemical Oceanography, where the community hopes to go and why, and actionable pathways to get there. A unifying concept among the discussions was that dissimilar funding structures and metrics of success may be required to accommodate the various levels of readiness and stages of knowledge development found throughout our community. In addition to the science, participants of the concurrent Dissertations Symposium in Chemical Oceanography (DISCO) XXV, a meeting of recent and forthcoming Ph.D. graduates in Chemical Oceanography, provided perspectives on how our field could show leadership in addressing long-standing diversity and early-career challenges that are pervasive throughout science. Here we summarize the COME ABOARD Meeting discussions, providing a synthesis of reflections and perspectives on the

    Over the last seven years we have led the creation and implementation of the Oceanography and Geoscience Scholars programs at Texas A&M University. Through these programs we have been able to provide scholarship support for 92 undergraduates in Geosciences and 29 graduate students in Oceanography. Fifty-seven undergraduate scholars have graduated in Geosciences: 30 undergraduate students in Meteorology, 7 in Geology, and 20 in Environmental Geosciences. Two students have graduated in other STEM disciplines. Twenty-four students are in the process of completing their undergraduate degrees in STEM disciplines. Twenty-three students have graduated with MS or PhD degrees in Oceanography and five PhD students are completing their dissertations. As specified in the program solicitation all of the scholars are academically talented students with demonstrated financial need as defined by the FAFSA (Free Application for Federal Student Aid). We have endeavored to recruit students from underrepresented groups. One-third of the undergraduate scholars were from underrepresented groups; 28% of the graduate students. We will present the challenges and successes of these programs.

    We describe the processes involved in the development of an information system which can assess how care given by a number of agencies could be monitored by those agencies. In particular, it addresses the problem of sharing information as the boundaries of each agency are crossed. It focuses on the care of one specific patient group--the rehabilitation of elderly patients in the community, which provided an ideal multi-agency setting. It also describes: how a stakeholder participative approach to information system development was undertaken, based in part on the Soft Systems Methodology (SSM) approach (Checkland, 1981, 1990); some of the difficulties encountered in using such an approach; and the ways in which these were addressed. The paper goes on to describe an assessment tool called SCARS (the Southampton Community Ability Rating Scale). It concludes by reflecting on the management lessons arising from this project. It also observes, inter alia, how stakeholders have a strong preference for simpler, non-IT based systems, and comments on the difficulties encountered by stakeholders in attempting to reconcile their perceptions of the needs of their discipline or specialty with a more patient-centred approach of an integrated system.

  3. 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.

    Project "Arctic Ocean sea ice and ocean circulation using satellite methods" (SATICE), is the first high-rate, high-precision, continuous GPS positioning experiment on sea ice in the Arctic Ocean. The SATICE systems collect continuous, dual-frequency carrier-phase GPS data while drifting on sea ice. Additional geophysical measurements also collected include ocean water pressure, ocean surface salinity, atmospheric pressure, snow-depth, air-ice-ocean temperature profiles, photographic imagery, and others, enabling sea ice drift, freeboard, weather, ice mass balance, and sea-level height determination. Relatively large volumes of data from each buoy are streamed over a satellite link to a central computer on the Internet in near real time, where they are processed to estimate the time-varying buoy positions. SATICE system obtains continuous GPS data at sub-minute intervals with a positioning precision of a few centimetres in all three dimensions. Although monitoring of sea ice motions goes back to the early days of satellite observations, these autonomous platforms bring out a level of spatio-temporal detail that has never been seen before, especially in the vertical axis. These high-resolution data allows us to address new polar science questions and challenge our present understanding of both sea ice dynamics and Arctic oceanography. We will describe the technology behind this new autonomous platform, which could also be adapted to other applications that require high resolution positioning information with sustained operations and observations in the polar marine environment, and present results pertaining to sea ice dynamics and physical oceanography.

    1988-01-01

    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).

    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

  13. 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

The circulation model has O(10(7)) degrees of freedom, is highly nonlinear and is driven by ocean, atmospheric and river influences at its boundaries. The surrogates provide accurate emulation of the full circulation code and run over 1000 times faster. Such fast dynamic surrogates will enable significant advances in ensemble forecasts in oceanography and weather.

    2005-09-01

    Oceanography is inherently interdisciplinary and, since its inception, has included the study of microbe-mineral interactions. From early studies of manganese nodules, to the discovery of hydrothermal vents, it has been recognized that microorganisms are involved at various levels in the transformation of rocks and minerals at and below the seafloor. Recent studies include mineral weathering at low temperatures and microbe-mineral interactions in the subseafloor "deep biosphere". A common characteristic of seafloor and subseafloor geomicrobiological processes that distinguishes them from terrestrial or near-surface processes is that they occur in the dark, one or more steps removed from the sunlight that fuels the near-surface biosphere on Earth. This review focuses on geomicrobiological studies and energy flow in dark, deep-ocean and subseafloor rock habitats.

    The investigation of marine viruses has advanced our understanding of ecology, evolution, microbiology, oceanography and virology. Significant findings discussed in this review include the discovery of giant viruses that have genome sizes and metabolic capabilities that distort the line between virus and cell, viruses that participate in photosynthesis and apoptosis, the detection of communities of viruses of all genomic compositions and the preeminence of viruses in the evolution of marine microbes. Although we have made great progress, we have yet to synthesize the rich archive of viral genomic data with oceanographic processes. The development of cutting edge methods such as single virus genomics now provide a toolset to better integrate viruses into the ecology of the ocean. Copyright © 2011 Elsevier B.V.

    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. Counsellors in primary care in Southampton: a questionnaire survey of their qualifications, working arrangements, and casemix.

    PubMed Central

    Clark, A; Hook, J; Stein, K

    1997-01-01

    BACKGROUND: There has been an upsurge of interest in counselling in primary care over the past five years. This has been stimulated by a growing demand for non-drug treatment of emotional disorders and by the extension of reimbursement for the costs of counsellors. Continued calls for careful evaluation have been largely unheeded in the face of heady growth. AIM: To establish the prevalence of counselling services in the 67 general practices in the Southampton and South West Hampshire Health District, and to describe in detail their qualifications, working arrangements, and casemix. METHOD: A questionnaire enquiring about counselling services was sent to all the general practices in the district. A second questionnaire was then posted to all the counsellors identified as working in these practices. RESULTS: Twenty-six (39%) practices employed one or more counsellors. Fundholding practices were four times more likely than non-fundholders to employ a counsellor. Most of the counselling work was short term (4-20 sessions). The most common presenting complaints were relationship problems, depression, anxiety, and bereavement. CONCLUSION: This descriptive study highlights the wide variation in the qualifications and training of counsellors. Until the issue of effectiveness is resolved through further research, the best safeguard of quality is to ensure that counsellors meet the appropriate training standards laid down by the British Association of Counsellors. Monitoring standards is a legitimate task for those commissioning health care who are increasingly responsible for reimbursement of a counsellor's salary. Counsellors who meet appropriate training criteria should be encouraged to pursue accreditation with the British Association of Counsellors. Those who do not meet these criteria should be encouraged to undergo additional training. PMID:9474822

    HyBIS is a low-cost, multi-purpose, highly maneuverable, fibre-optic controlled survey and sampling robotic underwater vehicle (RUV) capable of diving to 6000m. Built in the UK by Hydro-Lek Ltd. in collaboration with the National Oceanography Centre, Southampton, it has proven itself during recent discoveries of the deepest hydrothermal vents in the world, at 5100m deep in the Cayman Trough in the Caribbean and habitat mapping of seamounts in the Atlantic and Indian oceans . The vehicle has a modular design, with the top module being a command and power system that comprises power management, cameras, lights, hydraulics, thrusters and telemetry. The lower module can alternatively be a clam-shell sampling grab, a manipulator-arm and tool sled, a winch for instrument recovery, or an ocean bottom seismometer deployment module. Unlike a conventional ROV, HyBIS does not have any floatation, rather it is suspended by its umbilical cable directly from the ship. The advantage of direct suspension is that HyBIS can recover or deploy a payload of up to 700kg, although this comes at the price of reduced maneuverability compared to a 'normal' ROV. During its four years of service, HyBIS has, so far, accumulated an impressive list of achievements: recording over 450 hours of HD video footage, thousands of HD still images, collected geological, biological samples, as well as fluids and gas from over 40 different sites. It has also recovered two different seabed landers containing scientific equipment worth over £300k, and placed Ocean Bottom Seismometers onto the seafloor.

Vitamin D has also been implicated in postnatal muscle function but little is known about a role for antenatal 25(OH)D exposure in programming muscle development. Objective We investigated the associations between maternal plasma 25(OH)D status at 34 weeks gestation and offspring lean mass and muscle strength at 4 years of age. Design and setting A prospective UK population-based mother-offspring cohort: the Southampton Women’s Survey (SWS). Participants 12583 non-pregnant women were initially recruited into SWS, of which 3159 had singleton pregnancies. 678 mother-child pairs were included in this analysis. Main Outcomes Measured At 4 years of age, offspring assessments included hand grip strength (Jamar Dynamometer) and whole body DXA (Hologic Discovery) yielding lean mass and %lean mass. Physical activity was assessed by 7-day accelerometry (Actiheart) in a subset of children (n=326). Results Maternal serum 25(OH)D concentration in pregnancy was positively associated with offspring height-adjusted hand grip strength (β=0.10 SD/SD, p=0.013), which persisted after adjustment for maternal confounding factors, duration of breastfeeding and child’s physical activity at 4 years (β=0.13 SD/SD, p=0.014). Maternal 25(OH)D was also positively associated with offspring %lean mass (β=0.11 SD/SD, p=0.006), but not total lean mass (β=0.06, p=0.15). This however did not persist after adjustment for confounding factors (β=0.09 SD/SD, p=0.11). Conclusions This observational study suggests that intrauterine exposure to 25(OH)D during late pregnancy might influence offspring muscle development through an effect primarily on muscle strength rather than muscle mass.

    The report, second in a three set series, is an annotated bibliography of the pertinent literature, primarily from 1970 to the present. The literature discusses the physical oceanography of the complex region offshore of Cape Hatteras, North Carolina as it relates to the ocean circulation and fate of any discharges resulting from offshore oil and gas activity.

  8. Satellite observations of the ice cover of the Kuril Basin region of the Okhotsk Sea and its relation to the regional oceanography

    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.

    2010-01-01

    Paleophysical oceanography is the study of the behavior of the fluid ocean of the past, with a specific emphasis on its climate implications, leading to a focus on the general circulation. Even if the circulation is not of primary concern, heavy reliance on deep-sea cores for past climate information means that knowledge of the oceanic state when the sediments were laid down is a necessity. Like the modern problem, paleoceanography depends heavily on observations, and central difficulties lie with the very limited data types and coverage that are, and perhaps ever will be, available. An approximate separation can be made into static descriptors of the circulation (e.g., its water-mass properties and volumes) and the more difficult problem of determining transport rates of mass and other properties. Determination of the circulation of the Last Glacial Maximum is used to outline some of the main challenges to progress. Apart from sampling issues, major difficulties lie with physical interpretation of the proxies, transferring core depths to an accurate timescale (the "age-model problem"), and understanding the accuracy of time-stepping oceanic or coupled-climate models when run unconstrained by observations. Despite the existence of many plausible explanatory scenarios, few features of the paleocirculation in any period are yet known with certainty.

    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.

  11. Oceanography promotes self-recruitment in a planktonic larval disperser.

    The application of high-resolution genetic data has revealed that oceanographic connectivity in marine species with planktonic larvae can be surprisingly limited, even in the absence of major barriers to dispersal. Australia's southern coast represents a particularly interesting system for studying planktonic larval dispersal, as the hydrodynamic regime of the wide continental shelf has potential to facilitate onshore retention of larvae. We used a seascape genetics approach (the joint analysis of genetic data and oceanographic connectivity simulations) to assess population genetic structure and self-recruitment in a broadcast-spawning marine gastropod that exists as a single meta-population throughout its temperate Australian range. Levels of self-recruitment were surprisingly high, and oceanographic connectivity simulations indicated that this was a result of low-velocity nearshore currents promoting the retention of planktonic larvae in the vicinity of natal sites. Even though the model applied here is comparatively simple and assumes that the dispersal of planktonic larvae is passive, we find that oceanography alone is sufficient to explain the high levels of genetic structure and self-recruitment. Our study contributes to growing evidence that sophisticated larval behaviour is not a prerequisite for larval retention in the nearshore region in planktonic-developing species.

    A general assessment of the Superflux project is made in relation to marine science and oceanography. It is commented that the program clearly demonstrated the effectiveness of state-of-the-art technology required to study highly dynamic estuarine plumes, and the necessity of a broadly interdisciplinary, interactive remote sensing and shipboard program required to significantly advance the understanding of transport processes and impacts of estuarine outflows.

    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

    2013-04-01

    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

    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

    The contribution of tide-gauge data, which provide a unique monitoring of sea-level variability along the coasts of the world ocean, to operational oceanography is discussed in this paper. Two distinct applications that both demonstrate tide-gauge data utility when delivered in real-time are illustrated. The first case details basin-scale operational model validation of the French Mercator operational system applied to the North Atlantic. The accuracy of model outputs in the South Atlantic Bight both at coastal and offshore locations is evaluated using tide-gauge observations. These data enable one to assess the model's nowcasts and forecasts reliability which is needed in order for the model boundary conditions to be delivered to other coastal prediction systems. Such real-time validation is possible as long as data are delivered within a delay of a week. In the second application, tide-gauge data are assimilated in a storm surge model of the North Sea and used to control model trajectories in real-time. Using an advanced assimilation scheme that takes into account the swift evolution of model error statistics, these observations are shown to be very efficient to control model error, provided that they can be assimilated very frequently (i.e. available within a few hours).

    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

    During breeding, foraging marine birds are under biological, geographic, and temporal constraints. These contraints require foraging birds to efficiently process environmental cues derived from physical habitat features that occur at nested spatial scales. Mesoscale oceanography in particular may change rapidly within and between breeding seasons, and findings from well-studied systems that relate oceanography to seabird foraging may transfer poorly to regions with substantially different oceanographic conditions. Our objective was to examine foraging behavior of a pan-tropical seabird, the Masked Booby (Sula dactylatra), in the understudied Caribbean province, a moderately productive region driven by highly dynamic currents and fronts. We tracked 135 individuals with GPS units during May 2013, November 2013, and December 2014 at a regionally important breeding colony in the southern Gulf of Mexico. We measured foraging behavior using characteristics of foraging trips and used area restricted search as a proxy for foraging events. Among individual attributes, nest stage contributed to differences in foraging behavior whereas sex did not. Birds searched for prey at nested hierarchical scales ranging from 200 m—35 km. Large-scale coastal and shelf-slope fronts shifted position between sampling periods and overlapped geographically with overall foraging locations. At small scales (at the prey patch level), the specific relationship between environmental variables and foraging behavior was highly variable among individuals but general patterns emerged. Sea surface height anomaly and velocity of water were the strongest predictors of area restricted search behavior in random forest models, a finding that is consistent with the characterization of the Gulf of Mexico as an energetic system strongly influenced by currents and eddies. Our data may be combined with tracking efforts in the Caribbean province and across tropical regions to advance understanding of seabird

    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.

    In a recent study, Crosby et al. proposed a definition for vector correlation that has not been commonly used in meteorology or oceanography. This definition has both a firm theoretical basis and a rather complete set of desirable statistical properties. In this study, the authors apply the definition to practical problems arising in meteorology and oceanography. In the first of two case studies, vector correlations were calculated between subsurface currents for five locations along the southeastern shore of Lake Erie. Vector correlations for one sample size were calculated for all current meter combinations, first including the seiche frequency and then with the seiche frequency removed. Removal of the seiche frequency, which was easily detected in the current spectra, had only a small effect on the vector correlations. Under reasonable assumptions, the vector correlations were in most cases statistically significant and revealed considerable fine structure in the vector correlation sequences. In some cases, major variations in vector correlation coincided with changes in surface wind. The vector correlations for the various current meter combinations decreased rapidly with increasing spatial separation. For one current meter combination, canonical correlations were also calculated; the first canonical correlation tended to retain the underlying trend, whereas the second canonical correlation retained the peaks in the vector correlations.In the second case study, vector correlations were calculated between marine surface winds derived from the National Meteorological Center's Global Data Assimilation System and observed winds acquired from the network of National Data Buoy Center buoys that are located off the continental United States and in the Gulf of Alaska. Results of this comparison indicated that 1) there was a significant decrease in correlation between the predicted and observed winds with increasing forecast interval out to 72 h, 2) the technique

    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.

    An undergraduate online course in oceanography is based on the participation of each student in a series of virtual, at-sea, research expeditions, two of which are used to examine the tectonic processes at plate boundaries. The objective is to leverage the results of major federal research initiatives in the ocean sciences into effective learning tools with a long lifespan for use in undergraduate geoscience courses. These web-based expeditions examine: (1) hydrothermal vents along the divergent plate boundary at the Explorer Ridge and (2) the convergent plate boundary fault along the Nankai Trough, which is the objective of the multi-year NanTroSEIZE drilling program. Here we focus on the convergent plate boundary in NanTroSEIZE 3-D, which is based on a seismic survey supported through NSF-MARGINS, IODP and CDEX in Japan to study the properties of the plate boundary fault system in the upper limit of the seismogenic zone off Japan. The virtual voyage can be used in undergraduate classes at anytime, since it is not directly tied to the finite duration of a specific seagoing project, and comes in two versions, one that is being used in geoscience major courses and the other in non-major courses, such as the oceanography course mentioned above and a lower-division global studies course with a science emphasis. NanTroSEIZE in 3-D places undergraduate learning in an experiential framework as students participate on the expedition and carry out research on the structure of the plate boundary fault. Students learn the scientific background of the program, especially the critical role of international collaboration, and meet the chief scientists before joining the 3-D seismic imaging expedition to identify the active faults that were the likely sources of devastating earthquakes and tsunamis in Japan in 1944 and 1948. The initial results of phase I ODP drilling that began in 2007 are also reviewed. Students document their research on a worksheet that accompanies the

    The Minerals Management Service (MMS), Gulf of Mexico Outer Continental Shelf (OCS) Region sponsored a symposium on the Physical Oceanography of the Louisiana/Texas (LA/TX) Shelf in Galveston, Texas, on May 24-26, 1988. The symposium brought together a number of physical oceanographers, meteorologists, and ecologists to discuss the state of knowledge and to begin the planning process for a long-term study of shelf circulation covering the region from the mouth of the Mississippi River to approximately 24° latitude along the Mexican coast and from the shore out to a depth of approximately 500 m. The proposed study, to be a component of the ongoing MMS Environmental Studies Program, is expected to take place during the period 1989-1991. It is anticipated that the work will be done principally through contracts after a competitive procurement process. Specific charges to the participants were as follows:to assess the current state of knowledge concerning the circulation on the LA/TX shelfto identify significant gaps in that knowledgeto recommend a field measurement program to address these gapsto recommend a circulation modeling program for the LA/TX shelf that will improve MMS' oil spill risk assessmentsto identify and initiate coordination mechanisms and data-sharing arrangements with other proposed research efforts

    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.

    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.

    The German Research Foundation (DFG) funds Collaborative Research Centres (CRCs - in German: Sonderforschungsbereiche SFBs) that are generally applied for by one university, but may also incorporate neighbouring universities or non-university research institutions. SFBs are crossing the boundaries of disciplines, as well as faculties, departments, institutions and institutes. The funding of an SFB can be up to 12 years (3 x 4 years). Kiel University and GEOMAR Helmholtz Centre for Ocean Research Kiel received funding for the SFB 754 'Climate-biogeochemical interactions in the tropical ocean' in 2008. Currently, the centre is in its third phase comprising 17 scientific subprojects, one outreach project, a central coordination and management subproject and a subproject covering the research expeditions with a total project budget of 12 Mio Euro. Around 100 scientists of interdisciplinary research fields (e.g. physical oceanography, micro-biology, palaeontology, chemistry, modelling) are actively involved. Besides generating high profile research, gender equality, early career support and data management are complementary goals of SFBs requested by the DFG. Within the SFB 754 the scientific coordination office is responsible for developing concepts and strategies to cover these additional requirements and over the past eight years the SFB 754 has been successful in setting up profound programmes and various measures. Some of the SFB 754 practices have been taken up by other projects, and hence allowed the SFB 754 to serve as a role model for 'best practice' within marine sciences in Kiel. A main reason for the success of the SFB 754 to work towards the additional goals set out in the DFGs SFB programme is that the project is well tied into existing structures and builds upon outstanding management expertise available in Kiel. Three examples are highlighted here: • young scientists programme (closely linked to a graduate school (Integrated School of Marine Sciences

    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

    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.

    RTEMS CENTRE - Support and Maintenance Centre to RTEMS Operating System is a joint ESA/Portuguese Task Force initiative to develop a support and maintenance centre to the Real-Time Executive for Multiprocessor Systems (RTEMS). This paper gives a high level visibility of the progress, the results obtained and the future work in the RTEMS CENTRE [6] and in the RTEMS Improvement [7] projects. RTEMS CENTRE started officially in November 2006, with the RTEMS 4.6.99.2 version. A full analysis of RTEMS operating system was produced. The architecture was analysed in terms of conceptual, organizational and operational concepts. The original objectives [1] of the centre were primarily to create and maintain technical expertise and competences in this RTOS, to develop a website to provide the European Space Community an entry point for obtaining support (http://rtemscentre.edisoft.pt), to design, develop, maintain and integrate some RTEMS support tools (Timeline Tool, Configuration and Management Tools), to maintain flight libraries and Board Support Packages, to develop a strong relationship with the World RTEMS Community and finally to produce some considerations in ARINC-653, DO-178B and ECSS E-40 standards. RTEMS Improvement is the continuation of the RTEMS CENTRE. Currently the RTEMS, version 4.8.0, is being facilitated for a future qualification. In this work, the validation material is being produced following the Galileo Software Standards Development Assurance Level B [5]. RTEMS is being completely tested, errors analysed, dead and deactivated code removed and tests produced to achieve 100% statement and decision coverage of source code [2]. The SW to exploit the LEON Memory Management Unit (MMU) hardware will be also added. A brief description of the expected implementations will be given.

    2006-05-01

    trophic relations emphasize the difference in the productivity cycle in the eastern tropical Pacific compared to temperate or polar ecosystems, with no particular peaks in the stocks of either zooplankton or phytoplankton. Productivity is more dependent on local events like coastal upwelling or water circulation, especially in the equatorial countercurrent and around the equatorial cool-tongue. Micrograzers are very important in the tropics as are predatory mesozooplankton. Up to 70% of the daily primary productivity is consumed by microzooplankton, which thus regulates the phytoplankton stocks. Micrograzers are an important link between primary producers, including bacteria, and mesozooplankton, constituting up to 80% of mesozooplankton food. Oceanography affects zooplankton trophic relationships through spatial-temporal effects on primary productivity and on the distributions of metabolic factors, food organisms, and predators. This paper is part of a comprehensive review of the oceanography of the eastern tropical Pacific.

In the past, interruption of this deep water formation occurred several times causing hypoxic to anoxic conditions on the sea-floor leading to major ecological turnover. A better understanding of the interaction between climate and bottom water oxygenation is therefore essential in order to predict future oceanic responses. Presently, permanent (stable over decadal timescale) low-oxygen conditions occur naturally at mid-water depths in the northern Indian Ocean (Arabian Sea). Oxygen Minimum Zones (OMZ) are key areas to understand the hypoxic-anoxic events and their impact on the benthic ecosystem. In this context, a good knowledge of the ecology and life cycle adaptations of the benthic foraminiferal assemblages living in these low oxygen areas is essential. A series of multicores were recovered from three transects showing an oxygen gradient across the OMZ: the Murray Ridge, the Oman margin and the Indian margin. The stations located at the same depths showed slightly different oxygen concentrations and large differences in organic matter content. These differences are mainly related to the geographic location in the Arabian Sea. We investigated at these stations live and dead benthic

    The GOTO-SEE (Graduate students Onboard Teaching Oceanography - Scripps Educational Experience) cruises were conducted with two days of ship time off of Point Loma, CA, on the R/V Robert Gordon Sproul in July 2016. The cruises, funded through UC Ship Funds program, provided a unique training opportunity for graduate students to design, coordinate and conduct ship-based field experiments as well as teaching and mentoring students. The cruises allowed for instruction at sea for high school students in the UCSD Academic Connections program in two small classes: a two-week long Global Environmental Leadership and Sustainability Program and a 3-week long class entitled Wind, Waves and Currents: Physics of the Ocean World. Students in both classes assisted with the collection of data, including two repeat cross-shore vertical CTD sections with nutrient sampling, and the deployment and recovery of a 10-day moored vertical thermistor array. Additional activities included plankton net tows, sediment sampling, depth soundings, and simple experiments regarding light absorption in the ocean. The students later plotted the data collected as a class assignment and presented a scientific poster to their peers. Here, we present the lessons learned from the cruises as well as student responses to the unique in-the-field experience, and how those responses differed by curriculum.

    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

    2011-01-01

    This paper deals with the analysis of randomization effects in multi-centre clinical trials. The two randomization schemes most often used in clinical trials are considered: unstratified and centre-stratified block-permuted randomization. The prediction of the number of patients randomized to different treatment arms in different regions during the recruitment period accounting for the stochastic nature of the recruitment and effects of multiple centres is investigated. A new analytic approach using a Poisson-gamma patient recruitment model (patients arrive at different centres according to Poisson processes with rates sampled from a gamma distributed population) and its further extensions is proposed. Closed-form expressions for corresponding distributions of the predicted number of the patients randomized in different regions are derived. In the case of two treatments, the properties of the total imbalance in the number of patients on treatment arms caused by using centre-stratified randomization are investigated and for a large number of centres a normal approximation of imbalance is proved. The impact of imbalance on the power of the study is considered. It is shown that the loss of statistical power is practically negligible and can be compensated by a minor increase in sample size. The influence of patient dropout is also investigated. The impact of randomization on predicted drug supply overage is discussed. Copyright © 2010 John Wiley & Sons, Ltd.

    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 paper compares the oceanographic behavior during the heavy ice season associated with the cold 1979 winter 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 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. In the depths 300-1200 m, the water modification is caused by the advection of water from the northern Okhotsk. For 1979, this deeper water is also less saline, colder, and richer in oxygen than for the lighter ice years. The water modified in the Okhotsk enters the adjacent North Pacific through the Bussol' Strait, where for 1979 the adjacent waters are also cooler, less saline, and richer in oxygen down to a depth of 1000 m than for the lighter ice years.

    During the last decade, a rapid increase of birth locations for low-risk births, other than conventional obstetric units, has been seen in the Netherlands. Internationally some of such locations are called birth centres. The varying international definitions for birth centres are not directly applicable for use within the Dutch obstetric system. A standard definition for a birth centre in the Netherlands is lacking. This study aimed to develop a definition of birth centres for use in the Netherlands, to identify these centres and to describe their characteristics. International definitions of birth centres were analysed to find common descriptions. In July 2013 the Dutch Birth Centre Questionnaire was sent to 46 selected Dutch birth locations that might qualify as birth centre. Questions included: location, reason for establishment, women served, philosophies, facilities that support physiological birth, hotel-facilities, management, environment and transfer procedures in case of referral. Birth centres were visited to confirm the findings from the Dutch Birth Centre Questionnaire and to measure distance and time in case of referral to obstetric care. From all 46 birth locations the questionnaires were received. Based on this information a Dutch definition of a birth centre was constructed. This definition reads: "Birth centres are midwifery-managed locations that offer care to low risk women during labour and birth. They have a homelike environment and provide facilities to support physiological birth. Community midwives take primary professional responsibility for care. In case of referral the obstetric caregiver takes over the professional responsibility of care." Of the 46 selected birth locations 23 fulfilled this definition. Three types of birth centres were distinguished based on their location in relation to the nearest obstetric unit: freestanding (n = 3), alongside (n = 14) and on-site (n = 6). Transfer in case of referral was necessary for all

    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.

    In recent years, tapered optical fibers (TOFs) have attracted increasing interest and developed into a range of devices used in many practical applications ranging from optical communication, sensing to optical manipulation and high-Q resonators. Compared with conventional optical fibers, TOFs possess a range of unique features, such as large evanescent field, strong optical confinement, mechanical flexibility and compactness. In this review, we critically summarize the multimode interference in TOFs and some of its applications with a focus on our research project undertaken at the Optoelectronics Research Centre of the University of Southampton in the United Kingdom.

    A review of the first four years of the functioning of the birth centre at the Queen Victoria Medical Centre is presented. In that time, 1040 pregnant women were accepted for confinement there. Of these, 52 withdrew for non-obstetric reasons, while 470 were transferred to alternative obstetrical care--274 because of antepartum complications and 196 because of intrapartum problems. Therefore, 518 women were delivered in the birth centre. The care of the women is entrusted almost entirely to a team of midwives and this review demonstrates an enviable safety record.

    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.

  17. Brachiopod δ18O values do reflect ambient oceanography: Lacepede Shelf, southern Australia

    Although commonly used as proxies for attributes of ancient ocean waters, the δ18O values of brachiopods from modern seas are little studied. To evaluate the utility of brachiopods as recorders of regional oceanography, modern shells from the Lacepede Shelf (25 000 km2) of southern Australia were analyzed for δ18O, and the results were compared to the values of ambient seawater. Southern Ocean waters cover this area of extensive cool-water carbonate deposition, but there are distinct sectors of seasonal upwelling and lesser fluvial outflow. δ18O values of brachiopods across the environmental spectrum from 40 to 300 m water depth are in general isotopic equilibrium with surrounding seawater. Nevertheless, δ18O values from individual sample sites vary as much as 0.60‰. The area of cold-water upwelling in particular is clearly delimited by a group of high δ18O values. The range of values across this one shelf, on the order of 2.5‰, is similar to the range of values postulated on the basis of similar results for secular changes in many ancient oceans.

    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 weremore » 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.« less

  19. Perceptual centres in speech - an acoustic analysis

    NASA Astrophysics Data System (ADS)

    Scott, Sophie Kerttu

    Perceptual centres, or P-centres, represent the perceptual moments of occurrence of acoustic signals - the 'beat' of a sound. P-centres underlie the perception and production of rhythm in perceptually regular speech sequences. P-centres have been modelled both in speech and non speech (music) domains. The three aims of this thesis were toatest out current P-centre models to determine which best accounted for the experimental data bto identify a candidate parameter to map P-centres onto (a local approach) as opposed to the previous global models which rely upon the whole signal to determine the P-centre the final aim was to develop a model of P-centre location which could be applied to speech and non speech signals. The first aim was investigated by a series of experiments in which a) speech from different speakers was investigated to determine whether different models could account for variation between speakers b) whether rendering the amplitude time plot of a speech signal affects the P-centre of the signal c) whether increasing the amplitude at the offset of a speech signal alters P-centres in the production and perception of speech. The second aim was carried out by a) manipulating the rise time of different speech signals to determine whether the P-centre was affected, and whether the type of speech sound ramped affected the P-centre shift b) manipulating the rise time and decay time of a synthetic vowel to determine whether the onset alteration was had more affect on P-centre than the offset manipulation c) and whether the duration of a vowel affected the P-centre, if other attributes (amplitude, spectral contents) were held constant. The third aim - modelling P-centres - was based on these results. The Frequency dependent Amplitude Increase Model of P-centre location (FAIM) was developed using a modelling protocol, the APU GammaTone Filterbank and the speech from different speakers. The P-centres of the stimuli corpus were highly predicted by attributes of

    Accurate knowledge about the amount and dynamics of terrestrial gross primary productivity is an important component for understanding of ecosystem functioning and processes. Recently a new diagnostic model, Southampton Carbon Flux (SCARF), was developed to predict terrestrial gross primary productivity at regional to global scale based on a chlorophyll index derived from MERIS data. The model aims at mitigating some shortcomings in traditional light-use-efficiency based models by (i) using the fraction of photosynthetic active radiation absorbed only by the photosynthetic components of the canopy (FAPARps) and (ii) using the intrinsic quantum yields of C3 and C4 photosynthesis thereby reducing errors from land cover misclassification. Initial evaluation of the model in northern higher latitude ecosystems shows good agreement with in situ measurements. The current study calibrated and validated the model for a diversity of vegetation types across Africa in order to test its performance over a water limiting environment. The validation was based on GPP measurements from seven eddy flux towers across Africa. Sensitivity and uncertainty analyses were also performed to determine the importance of key biophysical and meteorological input parameters.Overall, modelled GPP values show good agreement with in situ measured GPP at most sites except tropical rainforest site. Mean daily GPP varied significantly across sites depending on the vegetation types and climate; from a minimum of -0.12 gC m2 day-1 for the semi-arid savannah to a maximum of 7.30 gC m2 day-1 for tropical rain forest ecosystems at Ankasa (Ghana). The model results have modest to very strong positive agreement with observed GPP at most sites (R2 values ranging from 0.60 for Skukuza in South Africa) and 0.85 for Mongu in Zambia) except tropical rain forest ecosystem (R2=0.34). Overall, the model has a stronger across-site coefficient of determination (R2=0.78) than MOD17 GPP product (R2=0.68). PAR and VPD

  2. The politics of patient-centred care.

    2015-10-01

    Despite widespread belief in the importance of patient-centred care, it remains difficult to create a system in which all groups work together for the good of the patient. Part of the problem may be that the issue of patient-centred care itself can be used to prosecute intergroup conflict. This qualitative study of texts examined the presence and nature of intergroup language within the discourse on patient-centred care. A systematic SCOPUS and Google search identified 85 peer-reviewed and grey literature reports that engaged with the concept of patient-centred care. Discourse analysis, informed by the social identity approach, examined how writers defined and portrayed various groups. Managers, physicians and nurses all used the discourse of patient-centred care to imply that their own group was patient centred while other group(s) were not. Patient organizations tended to downplay or even deny the role of managers and providers in promoting patient centredness, and some used the concept to advocate for controversial health policies. Intergroup themes were even more obvious in the rhetoric of political groups across the ideological spectrum. In contrast to accounts that juxtaposed in-groups and out-groups, those from reportedly patient-centred organizations defined a 'mosaic' in-group that encompassed managers, providers and patients. The seemingly benign concept of patient-centred care can easily become a weapon on an intergroup battlefield. Understanding this dimension may help organizations resolve the intergroup tensions that prevent collective achievement of a patient-centred system. © 2013 John Wiley & Sons Ltd.

    Maternal hyperglycemia in pregnancy is associated with greater adiposity in offspring. The glycemic index (GI) and glycemic load (GL) describe the glycemic response to carbohydrate ingestion. However, the influence of maternal dietary GI and GL in pregnancy on childhood adiposity is unknown. We examined relations of maternal dietary GI and GL in early and late pregnancy with offspring body composition. A total of 906 mother-child pairs from the prospective cohort the Southampton Women's Survey were included. Children underwent dual-energy X-ray absorptiometry measurements of body composition at birth and 4 and 6 y of age. Log-transformed fat mass and lean mass were standardized with a mean (±SD) of 0 ± 1. Maternal dietary GI and GL were assessed at 11 and 34 wk of gestation by using an administered food-frequency questionnaire. After control for potential confounders, both maternal dietary GI and GL in early pregnancy were positively associated with fat mass at 4 and 6 y of age [fat mass SDs per 10-unit GI increase: β = 0.43 (95% CI: 0.06, 0.80), P = 0.02 at 4 y of age; β = 0.40 (95% CI: 0.10, 0.70), P = 0.01 at 6 y of age; fat mass SDs per 50-unit GL increase: β = 0.43 (95% CI: 0.19, 0.67), P < 0.001 at 4 y of age; β = 0.27 (95% CI: 0.07, 0.47), P = 0.007 at 6 y of age]. In contrast, there were no associations between maternal dietary GI or GL in late pregnancy and offspring fat mass at these ages. Maternal dietary GI and GL were not associated with fat mass at birth or offspring lean mass at any of the ages studied. Higher maternal dietary GI and GL in early pregnancy are associated with greater adiposity in childhood. © 2014 American Society for Nutrition.

  4. The Physical Oceanography of Australia's Sunshine Coast

    2017-04-01

    Australia's Sunshine coast is located to the south of the Great Barrier Reef and Fraser Island between about 25 oS to 28 oS. With a width of nearly 70-80 km, the eastern Australian continental shelf is at its widest here. The shelf region is referred to as the Southeast Queensland Marine Coastal Zone due to its unique physical oceanographic characteristics. The most prominent large-scale oceanic feature is the southward flowing East Australian Current (EAC). It forms to the north of Fraser Island from Coral Sea outflows, intensifies, and follows the continental shelf as a swift continental shelf hugging current but variable in strength; stronger in the southern hemisphere summer and weaker in winter. Little attention has been paid to the physical oceanography of this region, although important physical processes take place that drive regional marine environmental conditions, drive cross-shelf exchanges and interactions with the EAC, and that represent marine connectivity processes significant to the larger scale eastern Australian fisheries. This presentation reviews recent discoveries that include the Southeast Fraser Island Upwelling System, the Fraser Island Gyre, and document the role of cyclonic mesoscale eddies in driving cross-shelf exchanges and contribute to the formation of the Fraser Island Gyre. The Southeast Fraser Island Upwelling System appears to be predominately driven by the interaction of the EAC with the continental shelf leading to the establishment of one of eight important marine ecological hotspots along the east Australian coast. The Fraser Island Gyre is most prominent during the southern hemisphere autumn and winter months. It is characterised by on-shelf northerly flow, turning eastward south of Fraser Island before joining the EAC. It emerges that cyclonic eddy formation as well as the south-easterly trade winds drive the gyre's establishment and strength.

    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.

    One objective of the "Ocean Autonomous Observation" team of the Laboratory of Oceanography of Villefranche-sur-mer is to develop new means to outreach our science activities to various audiences. Besides the scientific community, this includes students and targets the general public, school pupils, and stakeholders. In this context, we have acquired a digital video globe with tactile capabilities and we will present here the various applications that we have been developing. A first type of products concerns the visualization of oceanic properties (SST, salinity, density, Chla, O2, NO3, irradiance) by diving from the surface (generally from satellite data) into the Ocean interior (through the use of global data bases, Argo, WOA). In second place, specific applications deal with surface animations allowing highlighting the seasonality of some properties (Chla, SST, ice cover, currents; based on satellite as well as modeling outputs). Finally, we show a variety of applications developed using the tactile functionality of the spherical display. In particular real-time vertical profiles acquired by Bio-Argo floats become directly accessible for the entire open ocean. Such a new tool plus its novel applications has been presented to school children, and to the wider public (at the so-called "fête de la science") as well as to potential sponsors of our science-outreach activities. Their feedback has always been highly positive and encouraging in terms of impact. From the scientists point of view, the use of this new support can easily compete with the classical PowerPoint, is much more attractive and fun and undeniably helps to outreach the various aspects of our pluridisciplinary science.

    While it has long been recognized that the Mississippi River is the largest source of freshwater, nutrients and sediments to the Gulf of Mexico, many questions remain unanswered about the impacts of the material on oceanography of the system. Here we report on the results of a regional synthesis study that examined how the Mississippi River and its delta influence the oceanography, ecology and the economy of the Gulf of Mexico. By employing a series of expert-opinion working groups, and using multi-dimensional numerical physical oceanographic models coupled to in-situ environmental data, this project is working to quantify how variability in discharge, meteorological forcings, and seasonal conditions influence the spatial distribution of the Mississippi River plume and its influence. Results collected to date indicate that the dimensions of the river plume are closely coupled to discharge, but in a non-linear fashion, that incorporates fluxes, flow distributions, offshore and meteorological forcings in the context of the local bathymetry. Ongoing research is using these human and numerical tools to help further elucidate the impacts of this river on the biogeochemistry of the region, and the distribution of key macrofauna. Further work by this team is examining how the delta's impacts on the ecology of the region, and the role that the delta plays as both a source of material for key offshore fauna, and a barrier to dispersal. This information is being used to help further the development of a research agenda for the northern Gulf of Mexico that will be useful through the mid-21st century.

    After the twenty-first century, the Global Navigation Satellite System-Acoustic ranging (GNSS-A) technique detected geodetic events such as co- and postseismic effects following the 2011 Tohoku-oki earthquake and slip-deficit rate distributions along the Nankai Trough subduction zone. Although these are extremely important discoveries in geodesy and seismology, more accurate observation that can capture temporal and spatial changes are required for future earthquake disaster prevention. In order to upgrade the accuracy of the GNSS-A technique, it is necessary to understand disturbances in undersea sound speed structures, which are major error sources. In particular, detailed temporal and spatial variations are difficult to observe accurately, and their effect was not sufficiently extracted in previous studies. In the present paper, we reconstruct an inversion scheme for extracting the effect from GNSS-A data and experimentally apply this scheme to the seafloor sites around the Kuroshio. The extracted gradient effects are believed to represent not only a broad sound speed structure but also a more detailed structure generated in the unsteady disturbance. The accuracy of the seafloor positioning was also improved by this new method. The obtained results demonstrate the feasibility of using the GNSS-A technique to detect a seafloor crustal deformation for oceanography research.

    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.

    The University Medical Centre Utrecht (UMC Utrecht) has developed an eczema portal that combines e-consulting, monitoring and self-management training by a dermatology nurse online for patients and parents of young children with atopic dermatitis (AD). Patient satisfaction with the portal was high. It could be extended to become a Digital Eczema Centre for multidisciplinary collaboration between health-care providers from different locations and the patient. Before starting the construction of the Digital Eczema Centre, the feasibility was examined by carrying out a business case analysis. The purposes, strength and weaknesses showed that the Digital Eczema Centre offered opportunities to improve care for patients with AD. The financial analysis resulted in a medium/best case scenario with a positive result of euro50-240,000 over a period of five years. We expect that the Digital Eczema Centre will increase the accessibility and quality of care. The web-based patient record and the digital chain-of-care promote the involvement of patients, parents and multidisciplinary teams as well as the continuity and coordination of care.

    The Northeast Fisheries Science Center's (NEFSC) Student Drifters Program is providing education opportunities for students of all ages. Using GPS-tracked ocean drifters, various educational institutions can provide students with hands-on experience in physical oceanography, engineering, and computer science. In building drifters many high school and undergraduate students may focus on drifter construction, sometimes designing their own drifter or attempting to improve current NEFSC models. While learning basic oceanography younger students can build drifters with the help of an educator and directions available on the studentdrifters.org website. Once drifters are deployed, often by a local mariner or oceanographic partner, drifter tracks can be visualised on maps provided at http://nefsc.noaa.gov/drifter. With the lesson plans available for those interested in computer science, students may download, process, and plot the drifter position data with basic Python code provided. Drifter tracks help students to visualize ocean currents, and also allow them to understand real particle tracking applications such as in search and rescue, oil spill dispersion, larval transport, and the movement of injured sea animals. Additionally, ocean circulation modelers can use student drifter paths to validate their models. The Student Drifters Program has worked with over 100 schools, several of them having deployed drifters on the West Coast. Funding for the program often comes from individual schools and small grants but in the future will preferably come from larger government grants. NSF, Sea-Grant, NOAA, and EPA are all possible sources of funding, especially with the support of multiple schools and large marine education associations. The Student Drifters Program is a unique resource for educators, students, and scientists alike.

    In 1998, the Centro de Investigación Científica y de Educación Superior (CICESE) celebrated its 25th anniversary, which was the occasion to start the series of colloquia that take place every 2 years, the Coloquio Sobre la Oceanografía del Pacifico Oriental, in Ensenada. Two volumes were published in 2000 (Färber-Lorda, 2000) and in 2002 (Färber-Lorda, 2002), with some of the papers presented during the events. CICESE supported the edition of the first two volumes, as well as the meetings. The papers of this present volume were presented during the III Coloquio Sobre la Oceanografía del Pacifico Oriental. A special volume concerning different aspects of the consequences in México of the 1997-1998 El Niño/La Niña 1998-1999, was recently published in México (Badan et al., 2003); however, it is not restricted to the Pacific nor only to oceanography. The Eastern Pacific encompasses a very wide range of different biotic and abiotic conditions. Papers on topics from Alaska, to the Chilean Fjords of southern Chile, and from the Gulf of California to the 180° meridian, around the equator, are presented (see Fig. 1). Even if unity in the subjects is impossible to achieve, the information is important to assess the research performed in the area. Here, we give a brief description of the papers presented. Some general discussion is possible and some common features of phenomena like El Niño and La Niña, and the 1998/1999 regime-shift of the North Pacific, are exposed. For the first time a special volume is dedicated to this area, instead of a particular topic.

    The goal of integrated care is to offer a continuum of care that crosses the boundaries of public health, primary, secondary, and tertiary care. Integrated care is increasingly promoted for people with complex needs and has also recently been promoted in maternity care systems to improve the quality of care. Especially when located near an obstetric unit, birth centres are considered to be ideal settings for the realization of integrated care. At present, however, we know very little about the degree of integration in these centres and we do not know if increased levels of integration improve the quality of the care delivered. The Dutch Birth Centre Study is designed to evaluate birth centres and their contribution to the Dutch maternity care system. The aim of this particular sub-study is to classify birth centres in clusters with similar characteristics based on integration profiles, to support the evaluation of birth centre care. This study is based on the Rainbow Model of Integrated Care. We used a survey followed by qualitative interviews in 23 birth centres in the Netherlands to determine which integration profiles can be distinguished and to describe their discriminating characteristics. Cluster analysis was used to classify the birth centres. Birth centres were classified into three clusters: 1)"Mono-disciplinary-oriented birth centres" (n = 10): which are mainly owned by primary care organizations and established as physical facilities to provide an alternative birthplace for low risk births; 2) "Multi-disciplinary-oriented birth centres" (n = 6): which are mainly multi-disciplinary oriented and can be regarded as facilities to give birth, with a focus on integrated birth care; 3) "Mixed Cluster of birth centres" (n = 7): which have a range of organizational forms that differentiate them from centres in the other clusters. We identified a recognizable classification, with similar characteristics between birth centres in the clusters. The results of

    To elicit patient stakeholders' experience and perspectives about patient-centred care. Qualitative. A large urban healthcare system. Four patient stakeholders who are prostate cancer survivors. Experience and perspectives of patient stakeholders regarding patient-centred care and treatment decisions. Our patient stakeholders represented a diverse socio-demographic group. The patient stakeholders identified engagement and dialogue with physicians as crucial elements of patient-centred care model. The degree of patient-centred care was observed to be dependent on the situations. High severity conditions warranted a higher level of patient involvement, compared to mild conditions. They agreed that patient-centred care should not mean that patients can demand inappropriate treatments. An important attribute of patient-centred outcomes research model is the involvement of stakeholders. However, we have limited knowledge about the experience of patient stakeholders in patient-centred outcomes research. Our study indicates that patient stakeholders offer a unique perspective as researchers and policy-makers aim to precisely define patient-centred research and care.

    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.

    Agadir Canyon is one of the largest submarine canyons in the World, supplying giant submarine sediment gravity flows to the Agadir Basin and the wider Moroccan Turbidite System. While the Moroccan Turbidite System is extremely well investigated, almost no data from the source region, i.e. the Agadir Canyon, are available. Understanding why some submarine landslides remain as coherent blocks of sediment throughout their passage downslope, while others mix and disintegrate almost immediately after initial failure, is a major scientific challenge, which was addressed in the Agadir Canyon source region during Cruise MSM32. We collected ~ 1500 km of high-resolution seismic 2D-lines in combination with a dense net of hydroacoustic data. About 1000 km2 of sea floor were imaged during three deployments of TOBI (deep-towed sidescan sonar operated by the National Oceanography Centre Southampton). A total of 186 m of gravity cores and several giant box cores were recovered at more than 50 stations. The new data show that Agadir canyon is the source area of the world's largest submarine sediment flow, which occurred about 60,000 years ago. Up to 160 km3 of sediment was transported to the deep ocean in a single catastrophic event. For the first time, sediment flows of this scale have been tracked along their entire flow pathway. A major landslide area was identified south of Agadir Canyon. Landslide material enters Agadir canyon in about 2500 m water depth; the material is transported as debrite for at least another 200 km down the canyon. Initial data suggest that the last major slide from this source entered Agadir canyon at least 130,000 years ago. A large field of living deep-water corals was imaged north of Agadir canyon. To our knowledge, these are the first living cold water corals recovered off the coast of Morocco (except for the Gulf of Cadiz). They represent an important link between the known cold-water coral provinces off Mauritania and in the Gulf of Cádiz.

    To date, the most promising mitigation strategy for reducing global carbon emissions is Carbon Capture and Storage (CCS). The storage technology (i.e., CO2 geosequestration, CGS) consists of injecting CO2 into deep geological formations, specifically selected for such massive-scale storage. To guarantee the mechanical stability of the reservoir during and after injection, it is crucial to improve existing monitoring techniques for controlling CGS activities. We developed a comprehensive experimental program to investigate the integrity of the Sleipner CO2 storage site in the North Sea - the first commercial CCS project in history where 1 Mtn/y of CO2 has been injected since 1996. We assessed hydro-mechanical effects and the related geophysical signatures of three synthetic sandstones and samples from the Utsira Sand formation (main reservoir at Sleipner), at realistic pressure-temperature (PT) conditions and fluid compositions. Our experimental approach consists of brine-CO2 flow-through tests simulating variable inflation/depletion scenarios, performed in the CGS-rig (Fig. 1; Falcon-Suarez et al., 2017) at the National Oceanography Centre (NOC) in Southampton. The rig is designed for simultaneous monitoring of ultrasonic P- and S-wave velocities and attenuations, electrical resistivity, axial and radial strains, pore pressure and flow, during the co-injection of up to two fluids under controlled PT conditions. Our results show velocity-resistivity and seismic-geomechanical relations of practical importance for the distinction between pore pressure and pore fluid distribution during CGS activities. By combining geophysical and thermo-hydro-mechano-chemical coupled information, we can provide laboratory datasets that complement in situ seismic, geomechanical and electrical survey information, useful for the CO2 plume monitoring in Sleipner site and other shallow weakly-cemented sand CCS reservoirs.

    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.

    The overall aim of this paper is to draw combined, all-embracing conclusions based on a long-term multidisciplinary research programme on recycling centres in Sweden, focussing on working conditions, environment and system performance. A second aim is to give recommendations for their development of new and existing recycling centres and to discuss implications for the future design and organisation. Several opportunities for improvement of recycling centres were identified, such as design, layout, ease with which users could sort their waste, the work environment, conflicting needs and goals within the industry, and industrialisation. Combining all results from the research, which consisted of different disciplinary aspects, made it possible to analyse and elucidate their interrelations. Waste sorting quality was recognized as the most prominent improvement field in the recycling centre system. The research identified the importance of involving stakeholders with different perspectives when planning a recycling centre in order to get functionality and high performance. Practical proposals of how to plan and build recycling centres are given in a detailed checklist. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This discussion paper aims to synthesise the literature on patient-centred care from a range of health professions and to relate this to the field of rehabilitative audiology. Through review of the literature, this paper addresses five questions: What is patient-centred care? How is patient-centred care measured? What are the outcomes of patient-centred care? What are the factors contributing to patient-centred care? What are the implications for audiological rehabilitation? Literature review and synthesis. Publications were identified by structured searches in PubMed, Cinahl, Web of Knowledge, and PsychInfo, and by inspecting the reference lists of relevant articles. Few publications from within the audiology profession address this topic and consequently a review and synthesis of literature from other areas of health were used to answer the proposed questions. This paper concludes that patient-centred care is in line with the aims and scope of practice for audiological rehabilitation. However, there is emerging evidence that we still need to inform the conceptualisation of patient-centred audiological rehabilitation. A definition of patient-centred audiological rehabilitation is needed to facilitate studies into the nature and outcomes of it in audiological rehabilitation practice.

    We use seismic oceanography to document and analyze oceanic thermohaline fine structure across the Tyrrhenian Sea. Multichannel seismic (MCS) reflection data were acquired during the MEDiterranean OCcidental survey in April-May 2010. We deployed along-track expendable bathythermograph probes simultaneous with MCS acquisition. At nearby locations we gathered conductivity-temperature-depth data. An autonomous glider survey added in situ measurements of oceanic properties. The seismic reflectivity clearly delineates thermohaline fine structure in the upper 2,000 m of the water column, indicating the interfaces between Atlantic Water/Winter Intermediate Water, Levantine Intermediate Water, and Tyrrhenian Deep Water. We observe the Northern Tyrrhenian Anticyclone, a near-surface mesoscale eddy, plus laterally and vertically extensive thermohaline staircases. Using MCS, we are able to fully image the anticyclone to a depth of 800 m and to confirm the horizontal continuity of the thermohaline staircases of more than 200 km. The staircases show the clearest step-like gradients in the center of the basin while they become more diffuse toward the periphery and bottom, where impedance gradients become too small to be detected by MCS. We quantify the internal wave field and find it to be weak in the region of the eddy and in the center of the staircases, while it is stronger near the coastlines. Our results indicate this is because of the influence of the boundary currents, which disrupt the formation of staircases by preventing diffusive convection. In the interior of the basin, the staircases are clearer and the internal wave field weaker, suggesting that other mixing processes such as double diffusion prevail.

    The present study evaluated the extent to which child-care centre menus prepared in advance correspond with food and beverage items served to children. The authors identified centre and staff characteristics that were associated with matches between menus and what was served. Menus were collected from ninety-five centres in New York City (NYC). Direct observation of foods and beverages served to children were conducted during 524 meal and snack times at these centres between April and June 2010, as part of a larger study designed to determine compliance of child-care centres with city health department regulations for nutrition. Child-care centres were located in low-income neighbourhoods in NYC. Overall, 87 % of the foods and beverages listed on the menus or allowed as substitutions were served. Menu items matched with foods and beverages served for all major food groups by >60 %. Sweets and water had lower match percentages (40 and 32 %, respectively), but water was served 68 % of the time when it was not listed on the menu. The staff person making the food and purchasing decisions predicted the match between the planned or substituted items on the menus and the foods and beverages served. In the present study, child-care centre menus included most foods and beverages served to children. Menus planned in advance have potential to be used to inform parents about which child-care centre to send their child or what foods and beverages their enrolled children will be offered throughout the day.

    A critical analysis of occupational therapy practice in the corporate health care culture in a free market economy was undertaken to demonstrate incongruence with the profession's philosophical basis and espoused commitment to client-centred practice. The current practice of occupational therapy in the reimbursement-driven practice arena in the United States is incongruent with the profession's espoused philosophy and values of client-centred practice. Occupational therapy differentiates itself from medicine's expert model aimed at curing disease and remediating impairment, by its claim to client-centred practice focused on restoring health through occupational enablement. Practice focused on impairment and function is at odds with the profession's core tenet, occupation, and minimizes the lasting impact of interventions on health and well-being. The profession cannot unleash the therapeutic power of human occupation in settings where body systems and body functions are not occupation-ready at the requisite levels for occupational participation. Client-centred practice is best embodied by occupation-focused interventions in the natural environment of everyday living. Providing services that are impairment-focused in unfamiliar settings is not a good fit for client-centred practice, which is the unique, authentic, and sustainable orientation for the profession.

    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 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.

    Birth centres are regarded as settings where women with uncomplicated pregnancies can give birth, assisted by a midwife and a maternity care assistant. In case of (threatening) complications referral to a maternity unit of a hospital is necessary. In the last decade up to 20 different birth centres have been instituted in the Netherlands. This increase in birth centres is attributed to various reasons such as a safe and easy accessible place of birth, organizational efficiency in integration of care and direct access to obstetric hospital care if needed, and better use of maternity care assistance. Birth centres are assumed to offer increased integration and quality of care and thus to contribute to better perinatal and maternal outcomes. So far there is no evidence for this assumption as no previous studies of birth centres have been carried out in the Netherlands. The aims are 1) Identification of birth centres and measuring integration of organization and care 2) Measuring the quality of birth centre care 3) Effects of introducing a birth centre on regional quality and provision of care 4) Cost-effectiveness analysis 5) In depth longitudinal analysis of the organization and processes in birth centres. Different qualitative and quantitative methods will be used in the different sub studies. The design is a multi-centre, multi-method study, including surveys, interviews, observations, and analysis of registration data and documents. The results of this study will enable users of maternity care, professionals, policy makers and health care financers to make an informed choice about the kind of birth location that is appropriate for their needs and wishes.

    Surveys for seabirds and marine mammals were conducted in and near Sitka Sound, Alaska (Fig. 1) from the M/V Tiĝlax̂ during 12-16 July 2000 (Table 1, Fig. 1). The objective was to characterize the marine environment in the vicinity of St. Lazaria Island, one of ten seabird colonies monitored annually by the Alaska Maritime National Wildlife Refuge (See Dragoo et al. 2003). In addition to censusing seabirds and mammals encountered on line transects, local oceanography was characterized by measuring water temperature and salinity continuously at the sea surface, and by taking profiles of the water column on a series of CTD transects. The relative abundance of zooplankton and fish biomass was measured using a dual -frequency echosounder. Significant acoustic targets were sampled with a m id-water trawl net. Long-lines were se t twice to catch and characterize diets of large demersal fish species.Rosenthal et al. (1981 and 1982) studied the bottomfish component of the nearshore habitats in southeastern Alaska including the Sitka Sound area during the summers of 1980 and 1981, allowing comparisons of our findings to those from the earlier works. There are no previous surveys for seabirds or marine mammals in this area with which we can compare our surveys.

    The nitrogen-vacancy (NV) colour centre in diamond is an important physical system for emergent quantum technologies, including quantum metrology, information processing and communications, as well as for various nanotechnologies, such as biological and sub-diffraction limit imaging, and for tests of entanglement in quantum mechanics. Given this array of existing and potential applications and the almost 50 years of NV research, one would expect that the physics of the centre is well understood, however, the study of the NV centre has proved challenging, with many early assertions now believed false and many remaining issues yet to be resolved. This review represents the first time that the key empirical and ab initio results have been extracted from the extensive NV literature and assembled into one consistent picture of the current understanding of the centre. As a result, the key unresolved issues concerning the NV centre are identified and the possible avenues for their resolution are examined.

    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.

    Molybdenum is a refractory metal that is stable in a body-centred cubic structure at all temperatures before melting. Plastic deformation via structural transitions has never been reported for pure molybdenum, while transformation coupled with plasticity is well known for many alloys and ceramics. Here we demonstrate a structural transformation accompanied by shear deformation from an original <001>-oriented body-centred cubic structure to a <110>-oriented face-centred cubic lattice, captured at crack tips during the straining of molybdenum inside a transmission electron microscope at room temperature. The face-centred cubic domains then revert into <111>-oriented body-centred cubic domains, equivalent to a lattice rotation of 54.7°, and ~15.4% tensile strain is reached. The face-centred cubic structure appears to be a well-defined metastable state, as evidenced by scanning transmission electron microscopy and nanodiffraction, the Nishiyama–Wassermann and Kurdjumov–Sachs relationships between the face-centred cubic and body-centred cubic structures and molecular dynamics simulations. Our findings reveal a deformation mechanism for elemental metals under high-stress deformation conditions. PMID:24603655

    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.

    The waste management practices in primary healthcare centres of Iran were investigated in the present study. A total of 120 primary healthcare centres located across the country were selected using the cluster sampling method and the current situation of healthcare waste management was determined through field investigation. The quantities of solid waste and wastewater generation per outpatient were found to be 60 g outpatient(-1) day(-1) and 26 L outpatient(-1) day(-1), respectively. In all of the facilities, sharp objects were separated almost completely, but separation of other types of hazardous healthcare solid waste was only done in 25% of the centres. The separated hazardous solid waste materials were treated by incineration, temporary incineration and open burning methods in 32.5, 8.3 and 42.5% of the healthcare centres, respectively. In 16.7% of the centres the hazardous solid wastes were disposed of without any treatment. These results indicate that the management of waste materials in primary healthcare centres in Iran faced some problems. Staff training and awareness, separation of healthcare solid waste, establishment of the autoclave method for healthcare solid waste treatment and construction of septic tanks and disinfection units in the centres that were without access to a sewer system are the major measures that are suggested for improvement of the waste management practices.

    With the growing complexities in the contemporary health care system, there is a challenge of preparing nurses for the practice demands. To this end, learner-centred teaching has emerged in many nursing curricula in Canada and evidence indicates its effectiveness in developing the essential practice skills in nursing students. It is important to examine the experience of the clinical faculty members who implement learner-centred teaching, as doing so would provide an insight to the factors that may hinder the implementation of learner-centred teaching in the practice settings. This phenomenological study aimed to address two research questions: what does learner-centred teaching mean to clinical nurse faculty? What is the lived experience of clinical nursing faculty who incorporate learner-centred teaching? Ten clinical nurse faculty members who had at least two years of clinical teaching experience volunteered to participate in the study. Data were collected using a semi-structured interview guide and audio recorder. Additional data sources included a demographic survey and a reflective journal. Multiple sub-themes emerged from this study from which three significant themes were consolidated: diversity of meanings, facilitators of LCT, and barriers to LCT. However, an overarching theme of "learner-centred teaching in a non-learner-centred world" was coined from participants' accounts of their experiences of barriers in incorporating LCT in the practice settings. A collaborative effort between faculty and the stakeholders is paramount to a successful implementation of learner-centred teaching in practice settings. Copyright © 2018 The Authors.

  14. Reconciling evidence‐based medicine and patient‐centred care: defining evidence‐based inputs to patient‐centred decisions

    2015-01-01

    Abstract Evidence‐based and patient‐centred health care movements have each enhanced the discussion of how health care might best be delivered, yet the two have evolved separately and, in some views, remain at odds with each other. No clear model has emerged to enable practitioners to capitalize on the advantages of each so actual practice often becomes, to varying degrees, an undefined mishmash of each. When faced with clinical uncertainty, it becomes easy for practitioners to rely on formulas for care developed explicitly by expert panels, or on the tacit ones developed from experience or habit. Either way, these tendencies towards ‘cookbook’ medicine undermine the view of patients as unique particulars, and diminish what might be considered patient‐centred care. The sequence in which evidence is applied in the care process, however, is critical for developing a model of care that is both evidence based and patient centred. This notion derives from a paradigm for knowledge delivery and patient care developed over decades by Dr. Lawrence Weed. Weed's vision enables us to view evidence‐based and person‐centred medicine as wholly complementary, using computer tools to more fully and reliably exploit the vast body of collective knowledge available to define patients’ uniqueness and identify the options to guide patients. The transparency of the approach to knowledge delivery facilitates meaningful practitioner–patient dialogue in determining the appropriate course of action. Such a model for knowledge delivery and care is essential for integrating evidence‐based and patient‐centred approaches. PMID:26456314

    The Collège national des gynécologues obstétriciens français (CNGOF), in agreement with the Société de chirurgie gynécologique et pelvienne (SCGP), has set up a commission in 2017 to define endometriosis expert centres, with the aim of optimizing endometriosis care in France. The committee included members from university and general hospitals as well as private facilities, representing medical, surgical and radiological aspects of endometriosis care. Opinion of endometriosis patients' associations was obtained prior to writing this work. The final text was presented and unanimously validated by the members of the CNGOF Board of Directors at its meeting of October 13, 2017. Based on analysis of current management of endometriosis and the last ten years opportunities in France, the committee has been able to define the contours of endometriosis expert centres. The objectives, production specifications, mode of operation, missions and funding for these centres were described. The following missions have been specifically defined: territorial organization, global and referral care, communication and teaching as well as research and evaluation. Because of its daily impact for women and its economic burden in France, endometriosis justifies launching of expert centres throughout the country with formal accreditation by health authorities, ideally as part of the National Health Plan.

  18. Bottom friction. A practical approach to modelling coastal oceanography

    Coastal processes imply the interaction of the atmosphere, the sea, the coastline and the bottom. The spatial gradients in this area are normally large, induced by orographic and bathymetric features. Although nowadays it is possible to obtain high-resolution bathymetry, the details of the seabed, e.g. sediment type, presence of biological material and living organisms are not available. Additionally, these properties as well as bathymetry can also be highly dynamic. These bottom characteristics are very important to describe the boundary layer of currents and waves and control to a large degree the dissipation of flows. The bottom friction is thus typically a calibration parameter in numerical modelling of coastal processes. In this work, we assess this process and put it into context of other physical processes uncertainties influencing wind-waves and currents in the coastal areas. A case study in the North Sea is used, particularly the west coast of Denmark, where water depth of less than 30 m cover a wide fringe along the coast, where several offshore wind farm developments are being carried out. We use the hydrodynamic model MIKE 21 HD and the spectral wave model MIKE 21 SW to simulate atmosphere and tidal induced flows and the wind wave generation and propagation. Both models represent state of the art and have been developed for flexible meshes, ideal for coastal oceanography as they can better represent coastlines and allow a variable spatial resolution within the domain. Sensitivity tests to bottom friction formulations are carried out into context of other processes (e.g. model forcing uncertainties, wind and wave interactions, wind drag coefficient). Additionally, a map of varying bottom properties is generated based on a literature survey to explore the impact of the spatial variability. Assessment of different approaches is made in order to establish a best practice regarding bottom friction and coastal oceanographic modelling. Its contribution is also

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

    Carey, William M.

    2004-05-01

    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).

    Transform faults are the major discontinuities and define the main segment boundaries along spreading centres but their anatomy is poorly understood because of their complex seafloor morphology, even though they are observed at all types of spreading centres. Here, we present high-resolution seismic reflection images across the sedimented Andaman Sea Transform Fault where the sediments record the faulting and allow studying the evolution of the transform fault both in space and time. Furthermore, sediments allow the imaging of the faults down to the Moho depth that provides insight on the interplay between tectonic and magmatic processes. On the other hand, overlapping spreading centres (OSC) are small-scale discontinuities, possibly transient, and are observed only along fast or intermediate spreading centres. Exceptionally, an overlapping spreading centre is present at the slow spreading Andaman Sea Spreading Centre, which, we suggest, is due to the presence of thick sediments that hamper the efficient hydrothermal circulation allowing magma to stay much longer in the crust at different depths, and up to close to the segment ends, leading to the development of an overlapping spreading. The seismic reflection images across the OSC indicate the presence of large magma bodies in the crust. Seismic images also provide images of active faults allowing to study the link between faulting and magmatism. Interestingly, an earthquake swarm occurred at propagating limb of the OSC in 2006, after the great 2004 Andaman-Sumatra earthquake of Mw=9.3, highlighting the migration of the OSC westward. In this paper, we will show seismic reflection images and interpret these images in the light of bathymetry and earthquake data, and provide the anatomy of the ridge discontinuities along the slow spreading sedimented Andaman Sea Spreading Centre.

    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 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, poly-substance use, health determinants of indigenous peoples, street-involved youth and other vulnerable populations at risk of substance use problems.

    NASA Astrophysics Data System (ADS)

    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

    Management of advanced endometriosis frequently requires a multidisciplinary team approach and international guidelines suggest treatment in centres of expertise. Due to variability of published outcome data, prospective data collection and standardisation of reporting systems have been suggested to improve our understanding of surgical outcomes. The British Society for Gynaecological Endoscopy (BSGE) Endometriosis Centres were established to manage rectovaginal endometriosis, to collect treatment and outcome data, and to provide these data to patients, clinicians and healthcare commissioners. The BSGE Endometriosis Centres Project works on the principle of voluntary participation. Centres that would like to be recognised or accredited as a BSGE Endometriosis Centre need to fulfil a number of basic requirements including working in appropriate multidisciplinary clinical teams, auditing their outcome and having sufficient workload to maintain their surgical skills. The project has already had an impact on where the patients with advanced endometriosis are treated in the United Kingdom. Patients and healthcare professionals are becoming aware of their presence and more patients with the condition are being referred to these centres. It is also expected that the accredited centre status would be required for funding by healthcare commissioners for this type endometriosis. Copyright © 2013 S. Karger AG, Basel.

    The National Drug Dependence Treatment Centre (NDDTC) is a part of the All India Institute of Medical Sciences, a premier autonomous medical university in India. This article provides an account of its origin and its contribution to the field of substance use disorder at the national and international levels. Since its establishment, the NDDTC has played a major role in the development of various replicable models of care, the training of post-graduate students of psychiatry, research, policy development and planning. An assessment of the magnitude of drug abuse in India began in the early 1990s and this was followed by a National Survey on Extent, Patterns and Trends of Drug Abuse in 2004. Several models of clinical care have been developed for population subgroups in diverse settings. The centre played an important role in producing data and resource material which helped to scale up opioid substitution treatment in India. A nationwide database on the profile of patients seeking treatment (Drug Abuse Monitoring System) at government drug treatment centres has also been created. The centre has provided valuable inputs for the Government of India's programme planning. Besides clinical studies, research has also focused on pre-clinical studies. Capacity-building is an important priority, with training curricula and resource material being developed for doctors and paramedical staff. Many of these training programmes are conducted in collaboration with other institutions in the country. The NDDTC has received funding from several national and international organizations for research and scientific meetings, and, most recently (2012), it has been designated as a World Health Organization Collaborating Centre on Substance Abuse. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

    To investigate the association between postpartum stress as well as social support and the general health status of women recently discharged from postpartum nursing centres where the ritual of Tso-Yueh-Tzu is followed. Taiwanese women stay in postpartum nursing centres to take care of their newborn babies and perform the traditional Chinese ritual of Tso-Yueh-Tzu, the custom of a postpartum month-long rest. A non-experimental research design was used in the study. Two hundred and fifty-eight postpartum women who had stayed in postpartum nursing centres for at least 20 days were recruited at eight postpartum nursing centres in the Kaohsiung metropolitan area of southern Taiwan. They were administered the Hung Postpartum Stress Scale, the Social Support Scale and the Chinese Health Questionnaire. Women without minor psychiatric morbidity had higher social support, lower postpartum stress and longer length-of-stays in the postpartum care centre than women with minor psychiatric morbidity. Postpartum stress revolved around changes in body shape. A one-point increase in postpartum stress increased the likelihood that a mother would suffer minor psychiatric morbidity by 1.04 times; while giving birth to a boy decreased that likelihood by 0.51 times. This study found Tso-Yueh-Tzu as practised in postpartum nursing centres gave the postpartum women the opportunity to receive tangible support and, therefore, helped decrease postpartum stress and improved their general health. The greatest source of postpartum stress was concern over negative body changes. The postpartum nursing centre plays an important role in helping postpartum Taiwanese women observe the traditional ritual of Tso-Yueh-Tzu and in improving these women's general health. These centres may want to pay more attention to providing exercise that promotes body toning and relaxation.

    Data from the Southampton Women's Survey have established that women of lower educational attainment have poorer quality diets than those of higher educational attainment. This relationship is strong and graded such that for every increase in level of educational qualification, there is an increase in the likelihood that a woman will have a better quality diet. It is not wholly explained by socio-economic status. Qualitative research carried out in Southampton suggests that women of lower educational attainment may have a poorer diet because they feel they lack control over the food choices they make for themselves and their families. We set out to investigate the relationship between educational attainment, perceived control and quality of diet in a sample of women from Southampton. Cross-sectional study using structured interviews in which women's diet, educational attainment and perceived control were assessed. 19 Children's Centres and baby clinics in Southampton, UK. 372 women, median age 28 years. Quality of diet assessed by prudent diet score produced from principal components analysis of 20-item food frequency questionnaire, and perceived control assessed by a validated questionnaire. Women of lower educational attainment tended to have lower prudent diet scores and lower perceived control scores than women of higher educational attainment. Having a lower prudent diet score was associated with consuming fewer vegetables and vegetable dishes, less wholemeal bread and vegetarian food, and more chips and roast potatoes, meat pies, Yorkshire puddings and pancakes, crisps and snacks, white bread and added sugar. In a regression model both lower educational attainment and lower perceived control were associated with lower prudent diet scores, independent of the effects of confounding factors. However there was an interaction effect such that lower perceived control was only related to prudent diet score in the group of women of lower educational attainment. Women

  11. 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

    2010-01-01

    There appear to have been no studies of telemedicine in rural day care centres. We have assessed the feasibility of using telemedicine in eight rural day care centres in Pennsylvania, from the day care centres' perspective. The average number of children in these centres was 76 (range 20-150). The centres sent an average of 4.7 children home each month because of illness. Using telephone and face-to-face interviews, we assessed their perceived need for and familiarity with telemedicine, as well as their openness and preparedness for implementing telemedicine. Most day care centres reported a need for telemedicine and were open to learning how to use it. Some centres were concerned about adequate space for the equipment, but overall, the centres felt that their resources were adequate. Telemedicine in rural day care centres appears to be feasible, and would have the potential to save time and money for parents, as well as perhaps improving health care for children in rural areas.

    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.

    2014-01-01

    Background The Italian Association of Haemophilia Centres has developed a voluntary programme of professional accreditation of Haemophilia Centres, run by its members. Participation in the programme, which aims to foster staff involvement in clinical governance, includes both medical personnel and nurses. Materials and methods Accreditation is awarded provided the candidate Haemophilia Centre is able to adhere to a pre-established set of quality standards and meet a number of clinical and organisational requirements, previously defined on the basis of evidence-based medicine. Self-evaluation is the first step in the programme, followed by a site visit by a team of peer professionals experienced in quality auditing. Results The programme has so far involved 21 Italian Haemophilia Centres. The comparison between self- and peer-evaluation revealed less discrepancies for disease-related than for organisational requirements, the latter being met to a lesser degree by most Haemophilia Centres. Discussion This programme of professional accreditation developed by the Italian Association of Haemophilia Centres has the potential to describe, monitor and improve clinical and organisational performances in the management of patients with haemophilia and allied inherited coagulation disorders. It should also be seen as a contribution to the implementation of the strategy for improving professional governance in Haemophilia Centres. PMID:24922289

    Healthcare systems worldwide are confronted with major economic, organizational and logistical challenges. Historic evolution of health care has led to significant healthcare sector fragmentation, resulting in systemic inefficiencies and suboptimal resource exploitation. To attain a sustainable healthcare model, fundamental, system-wide improvements that effectively network, and ensure fulfilment of potential synergies between sectors, and include and facilitate coherent strategic planning and organisation of healthcare infrastructure are needed. Critically, they must be specifically designed to sustainably achieve peak performance within the current policy environment for cost-control, and efficiency and quality improvement for service delivery. We propose creation of a new healthcare cluster, to be embedded in existing healthcare systems. It consists of (i) local 24/7 walk-in virtually autonomous do-it-yourself Digital Medical Centres performing routine diagnosis, monitoring, prevention, treatment and standardized documentation and health outcome assessment/reporting, which are online interfaced with (ii) regional 24/7 eClinician Centres providing on-demand clinical supervision/assistance to Digital Medical Centre patients. Both of these are, in turn, online interfaced with (iii) the National Clinical Informatics Centre, which houses the national patient data centre (cloud) and data analysis units that conduct patient- and population-level, personalized and predictive(-medicine) intervention optimization analyses. The National Clinical Informatics Centre also interfaces with biomedical research and prioritizes and accelerates the translation of new discoveries into clinical practice. The associated Health Policy Innovation and Evaluation Centre rapidly integrates new findings with health policy/regulatory discussions. This new cluster would synergistically link all health system components in a circular format, enable not only access by all arms of the health

  18. European hospital managers' perceptions of patient-centred care.

    PubMed

    2015-01-01

    The spotlight has recently been placed on managers' responsibility for patient-centred care as a result of Mid Staffordshire NHS Foundation Trust failings. In previous research, clinicians reported that managers do not have an adequate structured plan for implementing patient-centred care. The purpose of this paper is to assess the perceptions of European hospital management with respect to factors affecting the implementation of a patient-centred approach. In total, 15 semi-structured interviews were conducted with hospital managers (n=10), expert country informants (n=2), patient organisations (n=2) and a user representative (n=1) from around Europe. Participants were purposively and snowball sampled. Interviews were analysed using framework analysis. Most participants felt that current levels of patient-centred care are inadequate, but accounted that there were a number of macro, meso and micro challenges they faced in implementing this approach. These included budget constraints, political and historical factors, the resistance of clinicians and other frontline staff. Organisational culture emerged as a central theme, shaped by these multi-level factors and influencing the way in which patient-centred care was borne out in the hospital. Participants proposed that the needs of patients might be better met through increasing advocacy by patient organisations and greater staff contact with patients. This study is the first of its kind to obtain management views from around Europe. It offers an insight into different models of how patient-centred care is realised by management. It indicates that managers see the value of a patient-centred approach but that they feel restricted by a number of factors at multiple levels.

  1. Professional relationships between general practitioners and pharmacists in health centres.

    1990-01-01

    The inclusion of pharmacies in health centres has created opportunities for general practitioners to become better acquainted with the potential contribution of pharmacists to health care. A qualitative study has been made to explore the extent to which this potential has been realized. Ten health centres with an integral pharmacy were selected, one from each of the regional health authorities in England which had at least one such health centre. Interviews were conducted with 13 general practitioners and 10 pharmacists working in the health centres. Nine general practitioners working in health centres without pharmacies and 10 community pharmacists were also interviewed. General practitioners' attitudes towards health centre pharmacists appeared to differ markedly from the attitudes of colleagues working in relative isolation from pharmacists. It appears that general practitioners working closely with the pharmacist develop a collaborative approach to health care. PMID:2271280

    From the moment a child is diagnosed as having cerebral palsy, families have to cope on a daily basis with the multifaceted challenges of life-long disability management. Family-centred service is embraced as a 'best practice' model because of accumulating evidence supporting its positive influence on parents and children's outcomes. Nevertheless, research comparing parent and provider perspectives on family-centred practices of educational service providers in education settings is scarce. The aims of this study were to compare the extent to which parents and conductors experience the service delivery in Tsad Kadima, the Association for Conductive Education in Israel, as being family-centred, as well as comparing parents' perception of different educational settings as being family-centred. Measurements of family-centeredness, the Israeli Measure of Processes of Care for families (MPOC-20) and for service providers (MPOC-SP), were administrated to 38 teacher conductors and 83 families of children with cerebral palsy (aged 1-14), from different conductive educational settings. Parents and conductors perceive Conductive Education service as being highly family centred in most domains, rating respectful and supportive care the highest and providing general information the lowest, thus indicating an area where improvements should be made. Parents perceived the service they receive to be more family-centred than conductor's perception about their own activities. In addition, educational setting (day care, pre-school and school) was found to be associated with parent's scores. The current study, which is the first to examine family-centred service provision in a conductive special education setting, from the perspectives of both parents and conductors, provides significant evidence for high-quality services in these settings. © 2016 John Wiley & Sons Ltd.

    Dopamine transporter (DAT) imaging with [(123)I]FP-CIT (DaTSCAN) is an established diagnostic tool in parkinsonism and dementia. Although qualitative assessment criteria are available, DAT quantification is important for research and for completion of a diagnostic evaluation. One critical aspect of quantification is the availability of normative data, considering possible age and gender effects on DAT availability. The aim of the European Normal Control Database of DaTSCAN (ENC-DAT) study was to generate a large database of [(123)I]FP-CIT SPECT scans in healthy controls. SPECT data from 139 healthy controls (74 men, 65 women; age range 20-83 years, mean 53 years) acquired in 13 different centres were included. Images were reconstructed using the ordered-subset expectation-maximization algorithm without correction (NOACSC), with attenuation correction (AC), and with both attenuation and scatter correction using the triple-energy window method (ACSC). Region-of-interest analysis was performed using the BRASS software (caudate and putamen), and the Southampton method (striatum). The outcome measure was the specific binding ratio (SBR). A significant effect of age on SBR was found for all data. Gender had a significant effect on SBR in the caudate and putamen for the NOACSC and AC data, and only in the left caudate for the ACSC data (BRASS method). Significant effects of age and gender on striatal SBR were observed for all data analysed with the Southampton method. Overall, there was a significant age-related decline in SBR of between 4 % and 6.7 % per decade. This study provides a large database of [(123)I]FP-CIT SPECT scans in healthy controls across a wide age range and with balanced gender representation. Higher DAT availability was found in women than in men. An average age-related decline in DAT availability of 5.5 % per decade was found for both genders, in agreement with previous reports. The data collected in this study may serve as a reference database for

  5. Near resonant bubble acoustic cross-section corrections, including examples from oceanography, volcanology, and biomedical ultrasound.

    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.

    A direct outcome of the exponential growth of macromolecular crystallography is the continuously increasing demand for synchrotron beam time, both from academic and industrial users. As more and more projects entail screening a profusion of sample crystals, fully automated procedures at every level of the experiments are being implemented at all synchrotron facilities. One of the major obstacles to achieving such automation lies in the sample recognition and centring in the X-ray beam. The capacity of UV light to specifically react with aromatic residues present in proteins or with DNA base pairs is at the basis of UV-assisted crystal centring. Although very efficient, a well known side effect of illuminating biological samples with strong UV sources is the damage induced on the irradiated samples. In the present study the effectiveness of a softer UV light for crystal centring by taking advantage of low-power light-emitting diode (LED) sources has been investigated. The use of UV LEDs represents a low-cost solution for crystal centring with high specificity. PMID:21169682

    The influence of centre vortices on dynamical chiral symmetry breaking is investigated through the light hadron spectrum on the lattice. Recent studies of the quark propagator and other quantities have provided evidence that centre vortices are the fundamental objects underpinning dynamical chiral symmetry breaking in {SU}(3) gauge theory. For the first time, we use the chiral overlap fermion action to study the low-lying hadron spectrum on lattice ensembles consisting of Monte Carlo, vortex-removed, and vortex-projected gauge fields. We find that gauge field configurations consisting solely of smoothed centre vortices are capable of reproducing all the salient features of the hadron spectrum, including dynamical chiral symmetry breaking. The hadron spectrum on vortex-removed fields shows clear signals of chiral symmetry restoration at light values of the bare quark mass, while at heavy masses the spectrum is consistent with a theory of weakly interacting constituent quarks.

    Drug adherence and quality of antiretroviral therapy (ART) services are the keys for the successful ART programme. Hence, an attempt has been made to assess ART centres in India from client perspectives that are receiving services from the centres. Data were gathered through exit interviews with 1366 clients from 27 ART centres that were selected on the basis of drug adherence and client load. Analyses revealed that more than 80 per cent of the clients reported overall satisfaction with the services availed from the centre and 60 per cent reported that the quality of life has improved to a great extent after getting ART. Most of the clients strongly demanded to open ART centre in each district for better access as that will increase drug adherence and eventually control the HIV progression. It has been found that as many as 14% of respondents, ever been on ART, reported non-adherence and 70% of them cited distance and economic factors as the reasons for non-adherence. Study concludes that while majority of the clients were satisfied with ART services, shortage of staff, high level of non-drug adherence, long distances and poor referring system are the weak areas requiring attention.

    Initiated by the Pleiadas Earth Observation Program, the CNES (French Space Agency) has developed a generic collaborative framework for its image quality centre, highly customisable for any upcoming expertise centre. This collaborative framework has been design to be used by a group of experts or scientists that want to share data and processings and manage interfaces with external entities. Its flexible and scalable architecture complies with the core requirements: defining a user data model with no impact on the software (generic access data), integrating user processings with a GUI builder and built-in APIs, and offering a scalable architecture to fit any preformance requirement and accompany growing projects. The CNES jas given licensing grants for two software companies that will be able to redistribute this framework to any customer.

    Stockton-Chalk, A. B.; Lanchester, B. S.; Ivchenko, N.; Lummerzheim, D.; Throp, K.

    SIF (Spectrographic Imaging Facility) is a Southampton University / University College London collaboration. The platform consists of a High Throughput Imaging Echelle Spectrograph, HiTIES, two photometers and a narrow angle auroral imager. The spectrograph has a mosaic filter; each of the three spectral panels are centred over/near important spectral features: Hbeta (486.1nm), N2+(470.9nm), N2+(465.2nm), thus allowing studies of proton and electron aurorae. The platform has been successfully deployed in Svalbard since November 1999. The purpose of the experiment was to take spectrographic measurements to study the relationship between proton and electron precipitation and to understand the nature of the precipitating spectrum of protons, both in energy and angular distributions. We present a study of the aurora observed in relation to solar wind pressure pulses.

    This study investigated attendees' motivation and motives for participation in day centres and their satisfaction with the rehabilitation, while also addressing the influence of day centre orientation (work- or meeting-place orientation), gender and age. Ninety-three Swedish day centre attendees participated in a cross-sectional study and completed questionnaires about motivation, motives, and satisfaction with the rehabilitation. Data were analysed with non-parametric statistics. The participants were highly motivated for going to the day centre and set clear goals for their rehabilitation. Female gender, but not age, was associated with stronger motivation. The strongest motives for going to the day centre were getting structure to the day and socializing. Attendees at work-oriented day centres more often expressed that they went there to get structure to the day and gain social status. Satisfaction with the rehabilitation was high, and the most common wishes for further opportunities concerned earning money and learning new things. The rehabilitation largely seemed to meet the attendees' needs, but the findings indicated that further developments were desired, such as participation in work on the open market and more work-like occupations in the day centre, accompanied by some kind of remuneration.

    Roth spots (white-centred retinal haemorrhages) were classically described as septic emboli lodged in the retina of patients with subacute bacterial endocarditis. Indeed many have considered Roth spots pathognomonic for this condition. More recent histological evidence suggests, however, that they are not foci of bacterial abscess. Instead, they are nonspecific and may be found in many other diseases. A review of the histology and the pathogenesis of these white-centred haemorrhages will be provided, along with the work-up of the differential diagnosis.

    The contribution of the "Institut Scientifique Chérifien", the oldest scientific research centre in Morocco, is reviewed since its creation almost a century ago. Planned in 1914 by the French protectorate of Morocco, this institute has played, since its effective creation in 1920, an important role in the development of several geosciences in North Africa, such as meteorology and climatology, geophysics (gravimetry, magnetism and especially seismology), geomorphology, geology and oceanography. After the independence of Morocco in 1955, several activities, such as meteorology, were transferred elsewhere, but others, such as seismology and magnetism, remained important elements of the centre until recent years. In addition to the research activities, its observatories and libraries that were built during the early years are unique in Northwest Africa.

    Abstract Objective To determine whether models of primary care service delivery differ in their provision of family-centred care (FCC) and to identify practice characteristics associated with FCC. Design Cross-sectional study. Setting Primary care practices in Ontario (ie, 35 salaried community health centres, 35 fee-for-service practices, 32 capitation-based health service organizations, and 35 blended remuneration family health networks) that belong to 4 models of primary care service delivery. Participants A total of 137 practices, 363 providers, and 5144 patients. Main outcome measures Measures of FCC in patient and provider surveys were based on the Primary Care Assessment Tool. Statistical analyses were conducted using linear mixed regression models and generalized estimating equations. Results Patient-reported FCC scores were high and did not vary significantly by primary care model. Larger panel size in a practice was associated with lower odds of patients reporting FCC. Provider-reported FCC scores were significantly higher in community health centres than in family health networks (P = .035). A larger number of nurse practitioners and clinical services on-site were both associated with higher FCC scores, while scores decreased as the number of family physicians in a practice increased and if practices were more rural. Conclusion Based on provider and patient reports, primary care reform strategies that encourage larger practices and more patients per family physician might compromise the provision of FCC, while strategies that encourage multidisciplinary practices and a range of services might increase FCC.

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

    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

We find that gauge field configurations consisting solely of smoothed centre vortices are capable of reproducing all the salient features of the hadronmore » spectrum, including dynamical chiral symmetry breaking. In conclusion, the hadron spectrum on vortex-removed fields shows clear signals of chiral symmetry restoration at light values of the bare quark mass, while at heavy masses the spectrum is consistent with a theory of weakly-interacting constituent quarks.« less

    Child immunisation is among the most cost-effective ways of preventing premature child deaths, and the potency of vaccines, crucial for vaccine efficacy, is dependent on effective management of the cold chain at all levels of vaccine handling. To assess the status of the cold chain at peripheral vaccine stores in Ethiopia. Institution based cross-sectional survey in two rural and one urban administrative areas were included in the study. Sixty seven health institutions providing static vaccination services were included in the study but cold chain system was assessed fully in only sixty four. Data were collected by interviewing health workers and by directly observing the cold chain equipment and records using structured forms. Conditions of the cold chain system were described based on 64 of the 67 centres visited, three were excluded because of non-functioning cold chain. Complete temperature record was observed in 37 (57.8%) of the centres. Thermometer was not available in four (6.3%) and thermometer reading was found to be outside the optimal range in another seven (10.9%) centres. Vaccine storage in the refrigerator was not proper in 47 (73.4%) centres. Majority of the centres had neither trained personnel nor budget for maintenance of the cold chain. There is a real danger of vaccines losing their potency at these centres even if they were potent on arrival. Relevant training for those handling the cold chain, improving the maintenance conditions of refrigerators and introduction of cold chain monitoring devises are recommended.

  20. 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.

  1. Using drama to improve person-centred dementia care.

    We implemented a 12-week drama-based educational intervention to introduce to dementia practitioners person-centred care that emphasizes the notion of embodied selfhood (defined as non-verbal self-expression). Person-centred dementia care guidelines emphasize the assessment of individual needs, and where appropriate, the use of non-pharmacological interventions before resorting to pharmacological management. However, dementia care is not consistent with these guidelines suggesting conceptual limitations and reliance on passive knowledge translation strategies. Focus groups and semi-structured interviews with practitioners (n = 24) in two nursing homes in central Canada were undertaken to assess the effectiveness of the drama-based components of the intervention. Our findings suggest that drama was effective as an educational modality, and helped implement the person-centred approach into practice. Significant practice outcomes included: new awareness that residents' body movements and dispositions can convey meaning; seeking biographical information from families; increased time efficiency; and supporting residents' independence. Our findings make an important contribution to person-centred dementia care by broadening the notion of personhood, and by facilitating implementation using drama. As an enhancement of person-centred care, the support of embodied selfhood may significantly improve residents' quality of life, quality of care, and practitioners' care-giving experience. © 2010 Blackwell Publishing Ltd.

  2. Tests for qualitative treatment-by-centre interaction using a 'pushback' procedure.

    PubMed

    Ciminera, J L; Heyse, J F; Nguyen, H H; Tukey, J W

    1993-06-15

    In multicentre clinical trials using a common protocol, the centres are usually regarded as being a fixed factor, thus allowing any treatment-by-centre interaction to be omitted from the error term for the effect of treatment. However, we feel it necessary to use the treatment-by-centre interaction as the error term if there is substantial evidence that the interaction with centres is qualitative instead of quantitative. To make allowance for the estimated uncertainties of the centre means, we propose choosing a reference value (for example, the median of the ordered array of centre means) and converting the individual centre results into standardized deviations from the reference value. The deviations are then reordered, and the results 'pushed back' by amounts appropriate for the corresponding order statistics in a sample from the relevant distribution. The pushed-back standardized deviations are then restored to the original scale. The appearance of opposite signs among the destandardized values for the various centres is then taken as 'substantial evidence' of qualitative interaction. Procedures are presented using, in any combination: (i) Gaussian, or Student's t-distribution; (ii) order-statistic medians or outward 90 per cent points of the corresponding order statistic distributions; (iii) pooling or grouping and pooling the internally estimated standard deviations of the centre means. The use of the least conservative combination--Student's t, outward 90 per cent points, grouping and pooling--is recommended.

    Attempts aimed at inducing food tolerance through oral food desensitization (OFD) for the treatment of IgE-mediated food allergies are increasing. In Italy, a number of allergy centres offer this procedure. To collect information on how these centres are organized, how patients are selected, the methods used to administer OFD and how adverse reactions are managed. A questionnaire was e-mailed to all the Italian allergy centres offering OFD. The survey shows a high degree of variability between centres. A correct diagnosis of food allergy is crucial for selecting patients for OFD. In the Italian allergy centres, oral food challenges are mostly open label (84%), but in 16% of cases they are single-blind (8%) or double-blind (8%). A high proportion of allergy centres (83%) offer OFD to children presenting forms of anaphylaxis triggered by traces--or very low doses--of food allergen. The majority of allergy centres (76%) enroll patients over 3 years of age, with 44% enrolling patients above the age of 5. Not-controlled asthma, unreliability of parents in the management of OFD and/or risk of adverse events, are the main reasons for exclusion from the procedure. Although OFD may sometimes be successful and may be considered a valid alternative to an elimination diet, further randomized controlled trials are needed, in order to clarify some controversial points, such as the characteristics of the child undergoing OFD, and the methods of food preparation and administration. Moreover, further studies should further investigate OFD safety, efficacy and costs.

  4. 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

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

    PubMed Central

    Simons, Richard; Kirkpatrick, Andrew

    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

    Roth spots (white-centred retinal haemorrhages) were classically described as septic emboli lodged in the retina of patients with subacute bacterial endocarditis. Indeed many have considered Roth spots pathognomonic for this condition. More recent histological evidence suggests, however, that they are not foci of bacterial abscess. Instead, they are nonspecific and may be found in many other diseases. A review of the histology and the pathogenesis of these white-centred haemorrhages will be provided, along with the work-up of the differential diagnosis. Images Figure 1 Figure 2 PMID:10211348

  10. Six essential roles of health promotion research centres: the Atlantic Canada experience

    PubMed Central

    Langille, Lynn L.; Crowell, Sandra J.; Lyons, Renée F.

    2009-01-01

    SUMMARY Over the past 20 years, the federal government and universities across Canada have directed resources towards the development of university-based health promotion research centres. Researchers at health promotion research centres in Canada have produced peer-reviewed papers and policy documents based on their work, but no publications have emerged that focus on the specific roles of the health promotion research centres themselves. The purpose of this paper is to propose a framework, based on an in-depth examination of one centre, to help identify the unique roles of health promotion research centres and to clarify the value they add to promoting health and advancing university goals. Considering the shifting federal discourse on health promotion over time and the vulnerability of social and health sciences to changes in research funding priorities, health promotion research centres in Canada and elsewhere may need to articulate their unique roles and contributions in order to maintain a critical focus on health promotion research. The authors briefly describe the Atlantic Health Promotion Research Centre (AHPRC), propose a framework that illustrates six essential roles of health promotion research centres and describe the policy contexts and challenges of health promotion research centres. The analysis of research and knowledge translation activities over 15 years at AHPRC sheds light on the roles that health promotion research centres play in applied research. The conclusion raises questions regarding the value of university-based research centres and challenges to their sustainability. PMID:19171668

  11. Clarifying the role of mean centring in multicollinearity of interaction effects.

    PubMed

    Shieh, Gwowen

    2011-11-01

    Moderated multiple regression (MMR) is frequently employed to analyse interaction effects between continuous predictor variables. The procedure of mean centring is commonly recommended to mitigate the potential threat of multicollinearity between predictor variables and the constructed cross-product term. Also, centring does typically provide more straightforward interpretation of the lower-order terms. This paper attempts to clarify two methodological issues of potential confusion. First, the positive and negative effects of mean centring on multicollinearity diagnostics are explored. It is illustrated that the mean centring method is, depending on the characteristics of the data, capable of either increasing or decreasing various measures of multicollinearity. Second, the exact reason why mean centring does not affect the detection of interaction effects is given. The explication shows the symmetrical influence of mean centring on the corrected sum of squares and variance inflation factor of the product variable while maintaining the equivalence between the two residual sums of squares for the regression of the product term on the two predictor variables. Thus the resulting test statistic remains unchanged regardless of the obvious modification of multicollinearity with mean centring. These findings provide a clear understanding and demonstration on the diverse impact of mean centring in MMR applications. ©2011 The British Psychological Society.

    In midwifery we espouse a woman centred care approach to practice, yet in midwifery education no valid instrument exists with which to measure the performance of these behaviours in midwifery students. To develop and validate an instrument to measure woman centred care behaviours in midwifery students. We identified four core concepts; woman's sphere, holism, self-determination and the shared power relationship. We mapped 18 individual descriptive care behaviours (from the Australian National Competency Standards for the Midwife) to these concepts to create an instrument to articulate and measure care behaviours that are specifically woman centred. Review by expert midwifery clinicians ensured face, content and construct validity of the scale and predictive validity and reliability were tested in a simulated learning environment. Midwifery students were video recorded performing a clinical skill and the videos were reviewed and rated by two expert clinicians who assessed the woman centred care behaviours demonstrated by the students (n=69). Test and re-test reliability of the instrument was high for each of the individual raters (Kappa 0.946 and 0.849 respectively p<0.001). However, when raters were compared there were differences between their scores suggesting variation in their expectations of woman centred care behaviours (Kappa 0.470, p<0.001). Midwifery students who had repeated exposures to higher levels of simulation fidelity demonstrated higher levels of woman centred care behaviours. The WCCS has implications for education and the wider midwifery profession in recognising and maintaining practice consistent with the underlying philosophy of woman centred care.

    2017-11-28

    Recognition of a need for patient-centred care is not new, however making patient-centred care a reality remains a challenge to organisations. We need empirical studies to extend current understandings, create new representations of the complexity of patient-centred care, and guide collective action toward patient-centred health care. To achieve these ends, the research aim was to empirically determine what organisational actions are required for patient-centred care to be achieved. We used an established participatory concept mapping methodology. Cross-sector stakeholders contributed to the development of statements for patient-centred care requirements, sorting statements into groupings according to similarity, and rating each statement according to importance, feasibility, and achievement. The resultant data were analysed to produce a visual concept map representing participants' conceptualisation of patient-centred care requirements. Analysis included the development of a similarity matrix, multidimensional scaling, hierarchical cluster analysis, selection of the number of clusters and their labels, identifying overarching domains and quantitative representation of rating data. The outcome was the development of a conceptual map for the Requirements of Patient-Centred Care Systems (ROPCCS). ROPCCS incorporates 123 statements sorted into 13 clusters. Cluster labels were: shared responsibility for personalised health literacy; patient provider dynamic for care partnership; collaboration; shared power and responsibility; resources for coordination of care; recognition of humanity - skills and attributes; knowing and valuing the patient; relationship building; system review evaluation and new models; commitment to supportive structures and processes; elements to facilitate change; professional identity and capability development; and explicit education and learning. The clusters were grouped into three overarching domains, representing a cross-sectoral approach

    2015-03-01

    Extracorporeal membrane oxygenation (ECMO) is a life-saving resource-intensive technology for patients with respiratory and/or circulatory failure. We aimed to evaluate outcome data from three Nordic paediatric centres comparing with data from the International Registry of the Extracorporeal Life Support Organization (ELSO) and selected high-volume single-centre studies. One-hundred nineteen patients < 19 years from 2002 to 2012 were enrolled. Data on demographics and outcome were collected using a standardised registration form. Outcome data were compared with the ELSO registry and high-volume single-centre studies. Demographics, indications and diagnosis were similar to the ELSO register. Survival after ECMO was similar to outcome data from the ELSO register, apart from paediatric cardiac ECMO, where a significantly better survival to discharge was seen in the Nordic centres (68% vs. 49%; P = 0.03). Comparison with high-volume centres in the period after 2005 demonstrated a significantly better survival after cardiac ECMO in a single high-volume centre study, whereas four studies had significantly lower survival after cardiac ECMO. No significant difference was seen in children receiving respiratory ECMO in the Nordic centres and high-volume centres. Survival after ECMO in three low-volume Nordic centres demonstrated comparable outcome data with ELSO data and data from high-volume centres. We believe regular quality assurance surveys, as the present study, should be performed in order to maintain excellent therapy within the individual ECMO centres. © 2015 The Acta Anaesthesiologica Scandinavica Foundation.

    According to a common definition, ocean literacy is an understanding of the ocean's influence on people and people influence on the ocean. An ocean-literate person is able to make informed and responsible decisions regarding the ocean and its resources. To this aim, this paper presents operational oceanographic tools developed to meet the needs of different users, and activities performed in collaboration with high school students to support new developments of the same tools. Operational oceanography allows to deal with societal challenges such as maritime safety, coastal and marine environment management, climate change assessment and marine resources management. Oceanographic products from the European Copernicus Marine Monitoring Service - CMEMS are transformed and communicated to public and stakeholders through adding-value chains (downstreaming), which consider advanced visualization, usage of multi-channels technological platforms and specific models and algorithms. Sea Situational Awareness is strategically important for management and safety purposes of any marine domain and, in particular, the Mediterranean Sea and its coastal areas. Examples of applications for sea situational awareness and maritime safety are here presented, through user-friendly products available both by web and mobile channels (that already reach more than 100.000 users in the Mediterranean area). Further examples of ocean literacy are web bulletins used to communicate the technical contents and information related to oceanographic forecasts to a wide public. They are the result of a collaboration with high school students, with whom also other activities on improving products visualization and online communication have been performed.

    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 aim of this study was to explore the variability in hospital admissions of patients with spondyloarthritis (SpA) in Spain, and the centre factors that may influence that variability. Descriptive cross-sectional study, part of the emAR II study, performed in Spain (2009-2010). Health records of patients with a diagnosis of SpA and at least one visit to the rheumatology units within the previous 2 years were reviewed. Variables related to hospital admissions, to the SpA, and to the patient and centre were collected. A multilevel logistic regression analysis of random intercept with non-random slopes was performed to assess variability between centres. From 45 centres, 1168 patients' health records were reviewed. Main SpA forms were ankylosing spondylitis (55.2 %) and psoriatic arthritis (22.2 %). A total of 248 admissions were registered for 196 patients (19.2 %, n = 1020). An adjusted variability of 17.6 % in hospitalizations between centres was noted. The following hospital-related factors showed a significant association with admissions: the total number of admissions of the centre, the existence of electronic admission, and the availability of ultrasound in rheumatology. However, these factors only explained 42.9 % of the inter-centre variability. The risk of a patient with SpA of being admitted could double (median OR 2.09), depending on the hospital where the patient was being managed. Hospital admissions of patients with SpA varied between hospitals due to centre characteristics. Further studies are needed to ascertain which specific factors may be causing the variation, as studied variables explained less than half of the variability.

    The photo-annealing of colour centres in yttria-stabilised zirconia (YSZ) was studied by electron paramagnetic resonance spectroscopy upon UV-ray or laser light illumination, and compared to thermal annealing. Stable hole centres (HCs) were produced in as-grown YSZ single crystals by UV-ray irradiation at room temperature (RT). The HCs produced by 200-MeV Au ion irradiation, as well as the F+-type centres (? centres involving oxygen vacancies) were left unchanged upon UV illumination. In contrast, a significant photo-annealing of the latter point defects was achieved in 1.4-MeV electron-irradiated YSZ by 553-nm laser light irradiation at RT. Almost complete photo-bleaching was achieved by laser irradiation inside the absorption band of ? centres centred at a wavelength 550 nm. Thermal annealing of these colour centres was also followed by UV-visible absorption spectroscopy showing full bleaching at 523 K. Colour-centre evolutions by photo-induced and thermally activated processes are discussed on the basis of charge exchange processes between point defects.

    This study of continental shelf processes affecting the oceanography of the South Atlantic Bight (SAB) is part of the interdisciplinary DOE-sponsored South Atlantic Bight Program. Our part of the program involves hydrographic and nutrient characteristics of the region. Current research efforts in the SAB Program are being focused on the inner shelf region where effects of bottom friction, local wind forcing, river and estuarine discharge, and tides, which are all small scale processes, are important. Our major accomplishment during the past year was the completion of the FLEX (Fall Experiment) field study. Since most of our data collection is computerized,more » preliminary hydrographic data analysis was done on board ship during the cruise and preliminary results are available. These results will be presented in this report. We are just beginning our standard data processing and data analysis procedures. We continued the processing and analysis of SPREX data collected during April 1985. Work has also continued on the older GABEX I and II data sets. 8 refs., 19 figs., 2 tabs.« less

    Objectives To estimate the cost-effectiveness of a planned birth in a birth centre compared with alternative planned places of birth for low-risk women. In addition, a distinction has been made between different types of locations and integration profiles of birth centres. Design Economic evaluation based on a prospective cohort study. Setting 21 Dutch birth centres, 46 hospital locations where midwife-led birth was possible and 110 midwifery practices where home birth was possible. Participants 3455 low-risk women under the care of a community midwife at the start of labour in the Netherlands within the study period 1 July 2013 to 31 December 2013. Main outcome measures Costs and health outcomes of birth for different planned places of birth. Healthcare costs were measured from start of labour until 7 days after birth. The health outcomes were assessed by the Optimality Index-NL2015 (OI) and a composite adverse outcomes score. Results The total adjusted mean costs for births planned in a birth centre, in a hospital and at home under the care of a community midwife were €3327, €3330 and €2998, respectively. There was no difference between the score on the OI for women who planned to give birth in a birth centre and that of women who planned to give birth in a hospital. Women who planned to give birth at home had better outcomes on the OI (higher score on the OI). Conclusions We found no differences in costs and health outcomes for low-risk women under the care of a community midwife with a planned birth in a birth centre and in a hospital. For nulliparous and multiparous low-risk women, planned birth at home was the most cost-effective option compared with planned birth in a birth centre. PMID:28893750

    Mitotic spindle position relies on interactions between astral microtubules nucleated by centrosomes and a rigid cortex. Some cells, such as mouse oocytes, do not possess centrosomes and astral microtubules. These cells rely only on actin and on a soft cortex to position their spindle off-centre and undergo asymmetric divisions. While the first mouse embryonic division also occurs in the absence of centrosomes, it is symmetric and not much is known on how the spindle is positioned at the exact cell centre. Using interdisciplinary approaches, we demonstrate that zygotic spindle positioning follows a three-step process: (1) coarse centring of pronuclei relying on the dynamics of an F-actin/Myosin-Vb meshwork; (2) fine centring of the metaphase plate depending on a high cortical tension; (3) passive maintenance at the cell centre. Altogether, we show that F-actin-dependent mechanics operate the switch between asymmetric to symmetric division required at the oocyte to embryo transition.

    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. 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. 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. 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

    The increasing quality and quantity (resolution in space, coverage in time, combinations of sensors in the Sentinel family) of information provided by Copernicus offer the possibility to analyse and predict coastal meteo-oceanography at an unprecedented level. This is a unique opportunity to develop the Copernicus coastal dimension to tackle the pressures of increasing population and activities. The combination of ocean/atmosphere/land observations from the Sentinel (S) 1/2/3, aligned with the availability of an increasing number of high-resolution numerical simulations (e.g. wave and current fields) in the Copernicus Marine Environment Monitoring Service (CMEMS) catalogue, should allow users to access proven representations of the coastal environment at a new level of understanding (e.g. wave diffraction at coastal "obstacles"), coupling (e.g. incorporating the land discharge into the coastal sea) and reliability for applications (e.g. hazards for coastal navigation). By adding periodic bathymetric up-dating and incorporating new assimilation routines it will be possible to achieve a new level of analysis for coastal seas. In the paper we shall present the CEASELESS project that addresses the multiple scales coexisting in littoral areas by developing new shallow water parameterizations, introducing them into coupled model suites (wind-wave-surge-current-land discharge) and producing new standards for coastal simulations and analyses. This will demonstrate the technical feasibility of an operational coastal service. The set of derived products will be ingested into the users' work routines, proving the economic feasibility of such a coastal extension. The level of conflicts in squeezed coastal zones, expected to grow in the face of climate change, will, thus, benefit directly from CEASELESS, establishing tangible contributions for a wide range of economic sectors. The mutual validation of satellite data, numerical results and in-situ observations will generate

    In this article, we argue for a conceptual move from family-centred care (FCC) to a child-centred care approach and the implications for clinical nursing practice. Firstly, we argue that the parents and professional dominance constructs an asymmetric relationship towards the child, which may take away the focus from the child; Secondly, we need to renew efforts to promote the fundamental principles of protection, promotion and participation rights for children and young people according to the United Nations Convention on the Rights of the Child declaration and thirdly, we need to strengthen the child's perspective and to view the child as an agent representing own experiences and wishes to be respected and negotiated. © The Author(s) 2016.

    The capacity of non-heat-aggregated monoclonal human immunoglobulins of different classes, to localize in murine splenic germinal centres within 24 h of intravenous injection has been investigated. It has been shown that at least trimerization of polyclonal IgG must occur before any germinal centre trapping is manifest. Studies of complement fixation by these IgG preparations in vivo, together with studies of the germinal centre trapping of various monoclonal immunoglobulins, have indicated that the sole structural requirement for germinal centre localization of immunoglobulin aggregates is the ability to fix complement. Results suggest that immunoglobulin aggregates are transported to germinal centres via membrane C3 receptors of mobile cells, and then are released with loss of complement to become fixed to dendritic macrophages by a separate mechanism.

    The paramagnetic centres used for ESR (Electron Spin Resonance) dating method should be thermally stable which is the main factor limiting the range of this method. In this work, thermal stabilities of the ESR centres in the cave deposites from the Aladaǧlar Massive and Alanya in Turkey has been investigated. The life times of the dating signal were calculated as about 4.0 and 3.7 years for G06 and G08 samples at the 10 °C depositing temperature. The activation energies of the centres are obtained the same, 0.7eV for both samples.

    Molecular dynamics simulation was used to verify a speculation of the existence of a certain face-centred cubic (FCC) to body-centred cubic (BCC) phase transformation pathway. Four FCC metals, Ni, Cu, Au and Ag, were stretched along the [1 0 0] direction at various strain rates and temperatures. Under high strain rate and low temperature, and beyond the elastic limit, the bifurcation of the FCC phase occurred with sudden contraction along one lateral direction and expansion along the other lateral direction. When the lattice constant along the expansion direction converged with that of the stretched direction, the FCC phase transformed into an unstressed BCC phase. By reducing the strain rate or increasing the temperature, dislocation or 'momentum-induced melting' mechanisms began to control the plastic deformation of the FCC metals, respectively.

    Spectra, polarization and decay kinetics of the triplet and singlet emission of Ga+ centres in CsBr:Ga crystals have been studied in the temperature range of 0.1 to 400 K. It has been found that the triplet AX and AT emission bands coincide. Two slow components have been observed in the decay kinetics of each emission at T < 1.5 K and explained by the tunnel splitting of the metastable minima of the corresponding triplet relaxed excited state. It points to the off-centre displacement of a Ga+ ion from a crystal lattice site both in the tetragonal (T) and in the trigonal (X) Jahn-Teller minima.

    To describe the organizational and operational capabilities of specialized centres for children with psychomotor disability in Abidjan, Republic of Côte d'Ivoire. This descriptive study was carried out from February to May, 2006 at the various specialized centres for children with psychomotor disability that exist in the district of Abidjan. The procedure comprised a clinical description of the disabled children admitted to these centres and an assessment of the centres' organization and operational capabilities. Six specialist centres for children with psychomotor disability were identified, namely the Infant Guidance Centre, the Awakening and Stimulation Centre for disabled Children, the "Sainte-Magdeleine" Centre, the Medical and Training Institute, the "Page Blanche" institute and the "Colombes Notre Dame de la Paix" Centre. Among the children, 97.15% were day patients, 66.37% were mentally challenged, 30.96% had psychomotor impairment and 2.66% had motor impairments. The level of organization varied but the centres nevertheless had operational administrative, medical and paramedical staff, despite the absence of certain specialties. However, the lack of personnel, equipment and infrastructure is hindering the delivery of adequate services to the children. In Abidjan District, reception centres for children with psychomotor impairments are essentially privately run. Organizational and operational performances were suboptimal, with a low carer-to-patient ratio. Reinforcement of the centres' operational capabilities appears to be necessary.

    Develop the patient-centred innovation questionnaire for hospital nurses and establish its validity and reliability. Patient-centred care has been adopted by health care managers in their efforts to improve health care quality. It is regarded as a core concept for developing innovation. A cross-sectional study was employed to collect data from hospital nurses in Taiwan. This study was divided into two stages: pilot study and main study. In the main study, 596 valid responses were collected. This study adopted reliability analysis, exploratory factor analysis, confirmatory factor analysis and selected nurse innovation scale as a criterion to test criterion-related validity. Five-dimension patient-centred innovation questionnaire was proposed: access and practicability, co-ordination and communication, sharing power and responsibility, care continuity, family and person focus. Each dimension demonstrated a reliability of 0.89-0.98. All dimensions had acceptable convergent and discriminate validity. The patient-centred innovation questionnaire and nurse innovation scale exhibited a significantly positive correlation. Patient-centred innovation questionnaire not only had a good theoretical basis but also had sufficient reliability and construct validity, and criterion-related validity. Patient-centred innovation questionnaire could give a measure for evaluating the implementation of patient-centred care and could be used as a management tool during the process of nurse innovation. © 2017 John Wiley & Sons Ltd.

    The NERC Data Assimilation Research Centre (DARC), a Centre of Excellence in Earth Observation, has been recently set up in the UK. DARC is a distributed centre, with participation from the universities of Reading, Oxford, Cambridge and Edinburgh, and the Rutherford Appleton Laboratory. It has strong links with the UK Met Office, and with European data assimilation groups. One of the remits of DARC is the exploitation of research satellite data (e.g. from ESA's Envisat, due to be launched in November 2001). This presentation will describe the participation of DARC in the Envisat programme. This participation involves: (1) the calibration/validation of Envisat data using an NWP assimilation system, and (2) the production of 4-d quality-controlled datasets of temperature, ozone and water vapour from Envisat using an NWP assimilation system.

    It is possible that people with psychiatric disabilities who visit day centres have previous work experiences that may be seen as resources for their current engagement in day centre activities. Research in this respect seems to lack, however. To investigate work experiences among attendees at day centres for people with psychiatric disabilities and relationships with current type of day centre (work-oriented, meeting place-oriented or mixed), engagement in day centre activities, motivation and socio-demographic and health-related factors. Seventy-seven attendees responded to questionnaires. Global Assessment of Functioning, GAF, was also used. Work was categorised into Group I (professionals, semi-professionals), Group II (clerical support, services workers) and Group III (e.g. craft workers, elementary occupations). Almost everyone had previously had open-market employment; more than half for ≥ 10 years. Group I was more common in mixed centres, Group II in meeting place-oriented ones and Group III in work-oriented ones. Group I more frequently had college degree and was rated high on GAF functioning. Women were over-represented in Group II, and men in Group III and in meeting place-oriented centres. Attending mixed centres was more likely when having a college degree, scoring high on GAF functioning and being highly engaged in activities. Attendees at work-oriented day centres were characterised by being motivated for spending time alone and reporting a diagnosis of psychosis. The participants had unused working capacity. No clear-cut relationships were found between work experiences and the investigated correlates.

    2013-09-01

    The present work deals mainly with the effect and the use of strain rate and temperature changes during cyclic deformation as a means to obtain valuable information on the thermally activated dislocation glide processes, based on the assessment of reversible changes of the thermal effective stress and of transient changes of the athermal stress. The importance of closed-loop testing in true plastic strain control with constant cyclic plastic strain rate throughout the cycle is explained and emphasized, especially with respect to the case of strain rate sensitive materials. Stress responses of face-centred cubic and body-centred cubic (bcc) metals to cyclic strain rate changes are presented to illustrate that the deformation modes of these two classes of materials differ characteristically at temperatures below that the so-called knee temperature of bcc metals. When such tests are performed in cyclic saturation, the temperature and strain rate dependence of bcc metals can be measured very accurately on one and the same specimen, permitting a thorough analysis of thermal activation.

    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.

    Women's participation in medicine and the need for gender equality in healthcare are increasingly recognised, yet little attention is paid to leadership and management positions in large publicly funded academic health centres. This study illustrates such a need, taking the case of four large European centres: Charité - Universitätsmedizin Berlin (Germany), Karolinska Institutet (Sweden), Medizinische Universität Wien (Austria), and Oxford Academic Health Science Centre (United Kingdom). The percentage of female medical students and doctors in all four countries is now well within the 40-60% gender balance zone. Women are less well represented among specialists and remain significantly under-represented among senior doctors and full professors. All four centres have made progress in closing the gender leadership gap on boards and other top-level decision-making bodies, but a gender leadership gap remains relevant. The level of achieved gender balance varies significantly between the centres and largely mirrors country-specific welfare state models, with more equal gender relations in Sweden than in the other countries. Notably, there are also similar trends across countries and centres: gender inequality is stronger within academic enterprises than within hospital enterprises and stronger in middle management than at the top level. These novel findings reveal fissures in the 'glass ceiling' effects at top-level management, while the barriers for women shift to middle-level management and remain strong in academic positions. The uneven shifts in the leadership gap are highly relevant and have policy implications. Setting gender balance objectives exclusively for top-level decision-making bodies may not effectively promote a wider goal of gender equality. Academic health centres should pay greater attention to gender equality as an issue of organisational performance and good leadership at all levels of management, with particular attention to academic enterprises

    Huang, Christina M; Kirchhof, Mark G

    Ultraviolet (UV) radiation is a human carcinogen and is associated with the development of skin cancer. The promotion of indoor tanning (IT) at fitness centres is of particular concern as it reinforces the idea that a tan is associated with health and fitness. The purpose of this study was to investigate the prevalence of IT in fitness centres, with an emphasis on determining the financial costs, adherence to regulations, and safety precautions. Ten cities, representing 9 different Canadian provinces, were chosen for the study. From each province, a minimum of 20 and a maximum of 30 fitness centres were randomly selected from the Yellow Pages website. Each fitness centre was contacted by the principal investigator and inquiries were made from a consumer's perspective. Of the 203 gyms surveyed, 43% (88/203) offered tanning facilities. Of these, 10.23% (9/88) were found to be noncompliant with the provincial IT regulations for age and/or time between tanning sessions. Despite the known risks of IT, not all fitness centres are compliant with provincial legislations regarding IT, and some continue to promote tanning access to minors.

    2014-01-01

    Patient-centred tobacco management is a pragmatic approach for helping smokers achieve their goals in terms of either cessation or harm reduction. However, the success of the approach is dependent on clinicians embracing and delivering it as intended. There are a number of structural and systemic organisational barriers which are limiting clinician-delivered patient-centred tobacco dependence. In response, 'whole system' approaches which help support clinicians in the delivery of patient-centred tobacco management are required. Health system changes to support clinicians and facilitate the delivery of patient-centred tobacco management are worth further investigation, particularly in settings where tobacco smoking rates are high. © 2013 Australasian Professional Society on Alcohol and other Drugs.

  18. The changing interface between district hospital cardiology and the major cardiac centres

    PubMed Central

    1997-01-01

    The national priority for reducing mortality and morbidity from cardiovascular disease, the resulting expansion in the number of consultant cardiologists, and the reforms of the National Health Service have produced significant changes in delivery of care for cardiac patients and in the relations between district general hospitals (DGH) and the old regional cardiac centres. 1.2 The British Cardiac Society, the Medical Royal Colleges of Physicians of London and Edinburgh, and the Royal College of Physicians and Surgeons of Glasgow established a working group to make recommendations on the most appropriate evolution of these changes to secure high quality care in a cost-effective and professionally rewarding environment. The principal conclusions of the working group were: i) The establishment of new cardiac catheterisation laboratories in DGHs remote from a major cardiac centre should be encouraged provided the workload is adequate to ensure efficient use of the facility. ii) Cardiologists working in districts close to a major centre should be encouraged to catheterise their patients at the centre. iii) Close liaison of the district cardiologist with a cardiac surgeon and interventionist is vitally important. iv) The centres will be required to provide tertiary care for emergency and urgent cases from their traditional catchment area, specialised expertise for the management of rare and difficult cases, and angioplasty. Some centres will also offer complex electrophysiology, and ablation techniques. v) The centres must also provide routine cardiology services for their local district, facilities for cardiac catheterisation for DGH cardiologists, and training for doctors, nurses, technicians, and radiographers. vi) Some centres will be linked with paediatric cardiology and paediatric cardiac surgical units. vii) District cardiac centres will be required to provide a full non-invasive diagnostic service and emergency care for patients referred by general practitioners

    Nurse middle managers are in an ideal position to facilitate patient-centred care. However, their contribution is underexposed in literature due to difficulties to articulate this in practice. This paper explores how nurse middle managers contribute to patient-centred care in hospitals. A combination of time-use analysis and ethnographic work was used to disclose their contribution to patient-centred care at a micro level. Sixteen nurse managers were shadowed for over 560 hours in four hospitals. Some nurse middle managers seldom contribute to patient-centred care. Others are involved in direct patient care, but this does not result in patient-centred practices. At one hospital, the nurse middle managers did contribute to patient-centred care. Here balancing between "organizing work" and "caring work" is seen as a precondition for their patient-centeredness. Other important themes are feedback mechanisms; place matters; with whom to talk and how to frame the issues at stake; and behavioral style. Both "hands-on" and "heads-on" caring work of nurse middle managers enhances their patient-centeredness. This study is the first of its kind to obtain insight in the often difficult to articulate "doings" of nurse middle managers with regard to patient-centred care through combining time-use analysis with ethnographic work. © 2017 John Wiley & Sons Ltd.

  1. A macro perspective for client-centred practice in curricula: Critique and teaching methods.

    Fleming-Castaldy, Rita P

    2015-07-01

    Client-centred practice is often eclipsed by social, economic, and political inequities. Ignoring these realities obstructs clients' goal attainment. The author advocates for the integration of a macro perspective inclusive of participation barriers and supports in occupational therapy curricula and seeks to motivate educators to adopt teaching approaches that develop students' abilities to address the complexities of client-centred practice. This article integrates a critical analysis of the literature on client-centred practice with reflexivity on disability studies and autoethnography. Educational standards require students to learn about the social, economic, and political contexts that impact on client-centred practice and the need for advocacy to enable participation. Theoretical support of a macro perspective for client-centred practice is strongly evident in the literature. Information on methods for teaching students how to actualize these concepts in practice is scant. Thus, strategies to inform the integration of a macro perspective into curricula and concrete activities to develop students' competencies for empowered client-centred practice are required. Educators have an ethical responsibility to critique their pedagogy to determine whether they are adequately preparing students for client-centred practice. The focus must move from teaching a micro perspective of client-centred practice to a macro perspective that enables occupational justice and empowerment.

    AIMS--To analyse the diagnostic differences in reporting tumour histopathology between a district general hospital and a regional oncology centre. METHODS--Tumour histopathology reports (n = 227) extracted from Bolton General Hospital files between 1988 and 1992 were compared with the corresponding Christie Hospital (oncology centre) reports, the same material having been seen at both hospitals. RESULTS--Diagnostic agreement existed in 77% of all cases. The incidence of major discrepancies was 8.37%. Of the diagnoses, 19 (36%) cases involved major discrepancies and 34 (64%) cases minor discrepancies. Most discrepancies occurred in the lymphoma group and involved subclassification of Hodgkin's and non-Hodgkin's lymphoma. Ki1 anaplastic large cell lymphoma and T cell rich B cell lymphoma were problematic diagnoses. The correct grading of follicle centre cell lymphomas using the Kiel classification was another problem area. In 19 cases certain aspects of immunohistochemistry produced discrepancies. In one case an incorrect diagnosis was made at the oncology centre and in another both centres gave an incorrect diagnosis. CONCLUSIONS--Areas of diagnostic difficulty mainly involve the subclassification of lymphomas. Review of tumour pathology by experts is recommended, at least in certain categories, to ensure correct diagnosis and uniformity in subclassification of tumours. PMID:7730487

  3. Educational inequalities in patient-centred care: patients' preferences and experiences

    PubMed Central

    2012-01-01

    Background Educational attainment is strongly related to specific health outcomes. The pathway in which individual patient-provider interactions contribute to (re)producing these inequalities has yet to be studied. In this article, the focus is on differences between less and more highly educated patients in their preferences for and experiences with patient-centred care., e.g. shared decision making, receiving understandable explanations and being able to ask questions. Methods Data are derived from several Consumer Quality-index (CQ-index) studies. The CQ-index is a family of standardized instruments which are used in the Netherlands to measure quality of care from the patient’s perspective. Results The educational level of patients is directly related to the degree of importance patients attribute to specific aspects of patient-centred care. It has a minor influence on the experienced level of shared decision making, but not on experiences regarding other aspects of patient-centred care. Conclusions All patients regard patient-centred care as important and report positive experiences. However, there is a discrepancy between patient preferences for patient-centred care on one hand and the care received on the other. Less educated patients might receive ‘too much’, and more highly educated patients ‘too little’ in the domains of communication, information and shared decision making. PMID:22900589

    Cystic Fibrosis diagnosis is confirmed using sweat test. The aim of our study was to evaluate current techniques and methodologies in use at Italian CF Care Centres. A series of questions related to the performance of the sweat test was collected by all CF Care Centres in Italy. Answers were compared with UK and NCCLS guidelines. 39/41 Centres replied to the questionnaire. A good adherence to guidelines was registered for storing samples before analysis in 90.9%, while performing CF diagnosis by at least two sweat tests, and chloride analysis were reported respectively in 100% and 75.7% of Centres. Some inconsistencies were registered for minimum acceptable sweat quantity and time to collect sweat inadequate in respectively 42.5% and 24.2% of Centres, while performing quality control procedures and referring to an external quality assessment scheme were found inadequate in respectively 54.6% and 100%. 57.6% didn't provide any appropriate analytical ranges and only 15.1% of Centres offered proper information to patients/parents. A report form, including sweat quantity, reference ranges and interpretation, was adequate only for 9.4 up to 41.4% of CF Centres. Our study showed areas of inconsistencies in sweat testing current practices in Italy and highlights the need for evidence based national guidelines to improve practice and management strategies.

    To evaluate the psychometric properties of the Arabic language person-centred climate questionnaire-staff version. There have been increasing calls for a person-centred rather than a disease-centred approach to health care. A limited number of tools measure the extent to which care is delivered in a person-centred manner, and none of these tools have been validated for us in Arab settings. The validated form of the person-centred climate questionnaire-staff version was translated into Arabic and distributed to 152 health care staff in teaching and non-teaching hospitals in Saudi Arabia. Statistical estimates of validity and reliability were used for psychometric evaluation. Items on the Arabic form of the person-centred climate questionnaire-staff version had high reliability (Cronbach's alpha .98). Cronbach's alpha values for the three sub-scales (safety, everydayness and community), were .96, .97 and .95 respectively. Internal consistency was also high and measures of validity were very good. Arabic form of the person-centred climate questionnaire-staff version provides a valid and reliable way to measure the degree of perceived person-centredness. The tool can be used for comparing levels of person-centredness between wards, units, and public and private hospitals. The tool can also be used to measure the extent of person-centredness in health care settings in other Arab countries. © 2017 John Wiley & Sons Ltd.

    The literature suggests that person-centred care can contribute to quality of life and wellbeing of nursing home residents, relatives and staff. However, there is sparse research evidence on how person-centred care can be operationalised and implemented in practice, and the extent to which it may promote wellbeing and satisfaction. Therefore, the U-Age nursing home study was initiated to deepen the understanding of how to integrate person-centred care into daily practice and to explore the effects and meanings of this. The study aims to evaluate effects and meanings of a person-centred and thriving-promoting intervention in nursing homes through a multi-centre, non-equivalent controlled group before-after trial design. Three nursing homes across three international sites have been allocated to a person-centred and thriving-promoting intervention group, and three nursing homes have been allocated to an inert control group. Staff at intervention sites will participate in a 12-month interactive educational programme that operationalises thriving-promoting and person-centred care three dimensions: 1) Doing a little extra, 2) Developing a caring environment, and 3) Assessing and meeting highly prioritised psychosocial needs. A pedagogical framework will guide the intervention. The primary study endpoints are; residents' thriving, relatives' satisfaction with care and staff job satisfaction. Secondary endpoints are; resident, relative and staff experiences of the caring environment, relatives' experience of visiting their relative and the nursing home, as well as staff stress of conscience and perceived person-centredness of care. Data on study endpoints will be collected pre-intervention, post-intervention, and at a six-month follow up. Interviews will be conducted with relatives and staff to explore experiences and meanings of the intervention. The study is expected to provide evidence that can inform further research, policy and practice development on if and how

    Mortality following pancreatoduodenectomy is related to centre volume although the optimal volume is not defined. Patients undergoing PD between 2001 and 2016 were identified from UK national databases. The effects of patient variables, centre volume and time period upon 90 day mortality were studied. 90 day mortality (970/14,935, 6.5%) was related to advanced age, comorbidity, diagnosis, ethnicity, deprivation, centre volume and time period. Mortality rates fell markedly from 10.0% in 2001-4 to 4.1% in 2013-16. There was no difference in 90 day mortality between high (36 -60 PD per year) and very high volume (>60) centres. However, patients operated upon at very high volume centres were more elderly (66, 58 -73 vs 65, 56 -72; median, IQR; p = 0.006), deprived (38.7 vs 34.6%; p < 0.001) and co morbid (48.9 vs 46.1%; p = 0.027). Although a plateau in the centre volume and mortality relationship appears to have been demonstrated those patients treated at the highest volume centres were at higher risk of mortality. This data suggests therefore that to further understand outcomes from specialist centres characteristics of the patient population should be defined, not just centre volume. Copyright © 2018.

    2011-12-01

    In February 2009 the Improving Maternity Services in Australia - The Report of the Maternity Services Review (MSR) was released and recommended improving women's access to and availability of birth centres. It was unclear if this was in response to an overwhelming request for birth centres in the submissions received by the commonwealth or a compromise for excluding homebirth from the maternity service reforms. The aim of this paper was to examine what was said in the submissions to the MSR about birth centres. Data for this study comprised 832 submissions to the MSR that are publicly available on the Commonwealth of Australia Department of Health and Ageing website. All 832 submissions were downloaded, and read for any mention of the words 'birth centre', 'birth center'. Content analysis was used to categorise and report the data. Of the 832 submissions to the MSR 197 (24%) mentioned birth centres while 470 (60%) of the submissions mentioned homebirth. Only 31 (4%) of the submissions to the Maternity Review mentioned birth centres without mentioning home birth also. Most of the submissions emphasised that 'everything should be on the menu' when it came to place of birth and care provider. Reasons for choosing a birth centre were identified as: 'the best compromise available, 'the right and natural way' and 'the birth centre as safe'. Women had certain requirements of a birth centre that included: 'continuity of carer', 'midwife led', 'a sanctum from medicalised care', 'resources to cope with demand', 'close to home', and 'flexible guidelines and admission criteria'. Women weighed up a series of requirements when deciding whether to give birth in a birth centre. The recommendation by the MSR to expand birth centres and ignore home birth is at odds with the strong view expressed that 'everything should be on the menu'. The requirements women described of birth centre care are also at odds with current trends. If there is to be an expansion of birth centres, service

    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

    Optically active point defects in crystals have gained widespread attention as photonic systems that could be applied in quantum information technologies. However, challenges remain in the placing of individual defects at desired locations, an essential element of device fabrication. Here we report the controlled generation of single negatively charged nitrogen-vacancy (NV-) centres in diamond using laser writing. Aberration correction in the writing optics allows precise positioning of the vacancies within the diamond crystal, and subsequent annealing produces single NV- centres with a probability of success of up to 45 ± 15%, located within about 200 nm of the desired position in the transverse plane. Selected NV- centres display stable, coherent optical transitions at cryogenic temperatures, a prerequisite for the creation of distributed quantum networks of solid-state qubits. The results illustrate the potential of laser writing as a new tool for defect engineering in quantum technologies, and extend laser processing to the single-defect domain.

    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

    The aim of this study was to explore cardiac patients' perception of patient-centred care. Despite patient's importance in the process of care, less attention has been paid to experiences and expectations of patients in definitions of patient-centred care. As patients are an important element in process of patient-centred care, organizing care programs according to their perceptions and expectations will lead to enhanced quality of care and greater patient satisfaction. This study is a descriptive qualitative study. Content analysis approach was performed for data analysis. Participants were 18 cardiac patients (10 women and 8 men) hospitalized in coronary care units of teaching hospitals affiliated to Tehran University of Medical Sciences. We collected the study data through conducting personal face-to-face semi-structured interviews. The participants' perceptions of patient-centred care fell into three main themes including managing patients uncertainty, providing care with more flexibility and establishing a therapeutic communication. The second theme consisted of two sub-themes: empathizing with patients and having the right to make independent decisions. Receiving patient-centred care is essential for cardiac patients. Attention to priorities and preferences of cardiac patients and making decisions accordingly is among effective strategies for achieving patient-centred care. Cardiac care unit nurses ought to be aware that in spite of technological developments and advances, it is still important to pay attention to patients' needs and expectations in order to achieve patient satisfaction. In planning care programs, they should consider accountability towards patients' needs, flexibility in process of care and establishing medical interactions as an effective strategy for improving quality of care. © 2014 British Association of Critical Care Nurses.

    Metalloproteins play indispensable roles in biology owing to the versatile chemical reactivity of metal centres. However, studying their reactivity in many metalloproteins is challenging, as protein three-dimensional structure encloses labile metal centres, thus limiting their access to reactants and impeding direct measurements. Here we demonstrate the use of single-molecule atomic force microscopy to induce partial unfolding to expose metal centres in metalloproteins to aqueous solution, thus allowing for studying their chemical reactivity in aqueous solution for the first time. As a proof-of-principle, we demonstrate two chemical reactions for the FeS4 centre in rubredoxin: electrophilic protonation and nucleophilic ligand substitution. Our results show that protonation and ligand substitution result in mechanical destabilization of the FeS4 centre. Quantum chemical calculations corroborated experimental results and revealed detailed reaction mechanisms. We anticipate that this novel approach will provide insights into chemical reactivity of metal centres in metalloproteins under biologically more relevant conditions.

    Community health centres are the main form of provision of primary care in China. There are three models: government managed, hospital managed and private. Our aim was to describe and compare primary care under the three ownership models. Four aspects of primary care were studied: services, organization, financing and human resources. Interviews were undertaken with 60 managerial and professional staff in 13 community health centres in the Pearl River Delta region in 2010. Three community health centres were selected in the capital city and two were selected from each of the other five cities. Thematic framework analysis was conducted. Government-managed community health centres received the largest public funding, followed by hospital-managed community health centres, while private community health centres received the least. Private community health centres were the smallest in scale and provided lower quality public health services compared with the other two models. Patient out-of-pocket costs accounted for the majority of the revenue in all models of community health centres despite improved government funding for preventive services. General challenges such as the shortage of public funding, the exclusion of migrants in the funding for preventive services, low capacity in human resources and the separation of clinical and preventive care in community health centres were identified in all three models of community health centres. The ownership and management of a community health centre greatly influence the service it provides. Private community health centres are in a disadvantaged position to deliver high quality clinical and preventive care. © The Author(s) 2015.

    There has been increased focus on recycling in Sweden during recent years. This focus can be attributed to external environmental factors such as tougher legislation, but also to the potential gains for raw materials suppliers. Recycling centres are important components in the Swedish total recycling system. Recycling centres are manned facilities for waste collection where visitors can bring, sort and discard worn products as well as large-sized, hazardous, and electrical waste. The aim of this paper was to identify and describe the main flows and layout types at Swedish recycling centres. The aim was also to adapt and apply production theory for designing and managing recycling centre operations. More specifically, this means using lean production principles to help develop guidelines for recycling centre design and efficient control. Empirical data for this research was primarily collected through interviews and questionnaires among both visitors and employees at 16 Swedish recycling centres. Furthermore, adapted observation protocols have been used in order to explore visitor activities. There was also close collaboration with a local recycling centre company, which shared their layout experiences with the researchers in this project. The recycling centres studied had a variety of problems such as queues of visitors, overloading of material and improper sorting. The study shows that in order to decrease the problems, the recycling centres should be designed and managed according to lean production principles, i.e. through choosing more suitable layout choices with visible and linear flows, providing better visitor information, and providing suitable technical equipment. Improvements can be achieved through proper planning of the layout and control of the flow of vehicles, with the result of increased efficiency and capacity, shorter visits, and cleaner waste fractions. The benefits of a lean production mindset include increased visitor capacity, waste

    2013-08-01

    To report an analysis and comparison of the concepts centring and opening meditation processes in health care. Centring and opening meditation processes are included in nursing theories and frequently recommended in health care for stress management. These meditation processes are integrated into emerging psychotherapy approaches and there is a rapidly expanding body of neuroscience research distinguishing brain activity associated with different types of meditation. Currently, there is a lack of theoretical and conceptual clarity needed to guide meditation research in health care. A search of healthcare literature between 2006-2011 was conducted using Alt HealthWatch, CINAHL, PsychNET and PubMed databases using the keywords 'centring' and 'opening' alone and in combination with the term 'meditation.' For the concept centring, 10 articles and 11 books and for the concept opening 13 articles and 10 books were included as data sources. Rodgers' evolutionary method of concept analysis was used. Centring and opening are similar in that they both involve awareness in the present moment; both use a gentle, effortless approach; and both have a calming effect. Key differences include centring's focus on the individual's inner experience compared with the non-dual, spacious awareness of opening. Centring and opening are overlapping, yet distinct meditation processes. The term meditation cannot be used in a generic way in health care. The differences between centring and opening have important implications for the further development of unitary-transformative nursing theories. © 2012 Blackwell Publishing Ltd.

    to assess the experiences with maternity care of women who planned birth in a birth centre and to compare them to alternative planned places of birth, by using the responsiveness concept of the World Health Organization. this study is a cross-sectional study using the ReproQ questionnaire filled out eight to ten weeks after birth. The primary outcome was responsiveness of birth care. Secondary outcomes included overall grades for birth care and experiences with the birth centre services. Regression analyses were performed to compare experiences among the planned places of birth. The study is part of the Dutch Birth Centre Study. the women were recruited by 82 midwifery practices in the Netherlands, within the study period 1 August 2013 and 31 December 2013. a total of 2162 women gave written consent to receive the questionnaire and 1181 (54.6%) women completed the questionnaire. women who planned to give birth at a birth centre: (1) had similar experiences as the women who planned to give birth in a hospital receiving care of a community midwife. (2) had significantly less favourable experiences than the women who planned to give birth at home. Differences during birth were seen on the domains dignity (OR=1.58, 95% CI=1.09-2.27) and autonomy (OR=1.77, 95% CI=1.25-2.51), during the postpartum period on the domains social considerations (OR=1.54, 95% CI=1.06-2.25) and choice and continuity (OR=1.43, 95% CI=1.00-2.03). (3) had significantly better experiences than the women who planned to give birth in a hospital under supervision of an obstetrician. Differences during birth were seen on the domains dignity (OR=0.51, 95% CI=0.31-0.81), autonomy (OR=0.59, 95% CI=0.35-1.00), confidentiality (OR=0.57, 95% CI=0.36-0.92) and social considerations (OR=0.47, 95% CI=0.28-0.79). During the postpartum period differences were seen on the domains dignity (OR=0.61, 95% CI=0.38-0.98), autonomy (OR=0.52, 95% CI=0.31-0.85) and basic amenities (OR=0.52, 95% CI=0.30-0.88).

  9. Assuring measurement quality in person-centred healthcare

    2018-03-01

    Is it realistic to aspire to the same kind of quality-assurance of measurement in person-centred care, currently being implemented in healthcare globally, as is established in the physical sciences and engineering? Ensuring metrological comparability (‘traceability’) and reliably declaring measurement uncertainty when assessing patient ability or increased social capital are however challenging for subjective measurements often characterised by large dispersion. Drawing simple analogies between ‘instruments’ in the social sciences—questionnaires, ability tests, etc—and engineering instruments such as thermometers does not go far enough. A possible way forward, apparently equally applicable to both physical and social measurement, seems to be to model inferences in terms of performance metrics of a measurement system. Person-centred care needs person-centred measurement and a full picture of the measurement process when man acts as a measurement instrument is given in the present paper. This complements previous work by presenting the process, step by step, from the observed indication (e.g. probability of success, P success, of achieving a task), through restitution with Rasch measurement theory, to the measurand (e.g. task difficulty). Rasch invariant measure theory can yield quantities—‘latent’ (or ‘explanatory’) variables such as task challenge or person ability—with characteristics akin to those of physical quantities. Metrological references for comparability via traceability and reliable estimates of uncertainty and decision risks are then in reach even for perceptive measurements (and other qualitative properties). As a case study, the person-centred measurement of cognitive ability is examined, as part of the EU project EMPIR 15HLT04 NeuroMet, for Alzheimer’s, where better analysis of correlations with brain atrophy is enabled thanks to the Rasch metrological approach.

    2018-04-01

    We study the propagation of finite bubbles in a Hele-Shaw channel, where a centred occlusion (termed a rail) is introduced to provide a small axially uniform depth constriction. For bubbles wide enough to span the channel, the system’s behaviour is similar to that of semi-infinite fingers and a symmetric static solution is stable. Here, we focus on smaller bubbles, in which case the symmetric static solution is unstable and the static bubble is displaced towards one of the deeper regions of the channel on either side of the rail. Using a combination of experiments and numerical simulations of a depth-averaged model, we show that a bubble propagating axially due to a small imposed flow rate can be stabilised in a steady symmetric mode centred on the rail through a subtle interaction between stabilising viscous forces and destabilising surface tension forces. However, for sufficiently large capillary numbers Ca, the ratio of viscous to surface tension forces, viscous forces in turn become destabilising thus returning the bubble to an off-centred propagation regime. With decreasing bubble size, the range of Ca for which steady centred propagation is stable decreases, and eventually vanishes through the coalescence of two supercritical pitchfork bifurcations. The depth-averaged model is found to accurately predict all the steady modes of propagation observed experimentally, and provides a comprehensive picture of the underlying steady bifurcation structure. However, for sufficiently large imposed flow rates, we find that initially centred bubbles do not converge onto a steady mode of propagation. Instead they transiently explore weakly unstable steady modes, an evolution which results in their break-up and eventual settling into a steady propagating state of changed topology.

    The cw laser diode pumping of an (F +2) ∗ colour centre laser has been recently demonstrated in our laboratory. The intensity of the pumping diode can easily be hf modulated. We present here the first experiments in which the colour centre laser is synchronously pumped at the mode spacing frequency, resulting in the emission of clean, regularly spaced pulses. The opto-electronic feedback is a very promising method of obtaining such a pulsed operation of a diode pumped colour centre laser without the use of an external hf oscillator.

    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

    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. © The Author(s) 2015.

    Under the auspices of the United Kingdom Haemophilia Doctors Organisation (UKHCDO) the UK Comprehensive Care Haemophilia Centres (CCCs) have undergone a three yearly formal audit assessment since 1993. This report describes the evolution of the audit process and details the findings of the most recent audit round, the sixth since inception. The audit reports from the 2009 audit round were reviewed by the audit organizing group and a structured analysis of the data was compiled. CCCs in the UK offer a high standard of comprehensive care services. The main areas of concern were the state of the premises (seven centres), lack of dental services (seven centres), physiotherapy (seven centres) and social work support (11 centres). Major concerns were identified at eight centres requiring a formal letter from the chairman of UKHCDO to the chief executive of the host trust. Since inception of the triennial audit process centre report recommendations have resulted in major improvements in the services available at UK CCCs. The audit process is considered to be a highly effective means of improving the quality of care for patients with bleeding disorders and can be used as a model for the introduction of a similar process in other countries. © 2012 Blackwell Publishing Ltd.

    The Nordic Geodetic Commission (NKG) has launched a joint NKG GNSS Analysis Centre that aims to routinely produce high qualityGNSS solutions for the common needs of the NKG and the Nordic and Baltic countries. A consistent and densified velocity field is needed for the constraining of the gla-cial isostatic adjustment (GIA) modelling that is a key component of maintaining the national reference frame realisations in the area. We described the methods of the NKG GNSS Analysis Centre including the defined processing setup for the local analysis centres (LAC) and for the combination centres.We analysed the results of the first 2.5 years (2014.5-2016). The results showed that different subnets were consistent with the combined solution within 1-2 mm level. We observed the so called network effect affecting our reference frame alignment. However, the accuracy of the reference frame alignment was on a few millimetre level in the area of the main interest (Nordic and Baltic Countries). TheNKGGNSS AC was declared fully operational in April 2017.

    2018-04-21

    How does person-centred leadership manifest in clinical nursing. Person-centred practice fosters healthful relationships and is gaining increasing attention in nursing and healthcare, but nothing is known about the influence of a person-centred approach to leadership practice. Most leadership models used in nursing were originally developed outside of nursing. A three year participatory action research study where participant leaders planned, researched and learned from their practice development. After an orientation phase, four action spirals focused on: critical and creative reflective inquiries into leadership practice change; leading the implementation and evaluation of a new nursing system; facilitating storytelling sessions with staff and annually reflecting on personal leadership change. Multiple data gathering methods offered insight into leadership development from several perspectives. Critical and creative thematic data analysis revealed a set of attributes, relational processes and contextual factors that influenced the being and becoming of a person-centred leader. Comparing the findings with nursing leadership literature supports a conceptual framework for person-centred leadership. Person-centred leadership is a complex, dynamic, relational and contextualised practice that aims to enable associates and leaders achieve self-actualisation, empowerment and wellbeing.

    A classification model was developed to simplify planning of personnel at dialysis centres. This model predicted the care burden based on dialysis characteristics. However, patient characteristics and different dialysis centre categories might also influence the amount of care time required. To determine if there is a difference in care burden between different categories of dialysis centres and if specific patient characteristics predict nursing time needed for patient treatment. An observational study. Two hundred and forty-two patients from 12 dialysis centres. In 12 dialysis centres, nurses filled out the classification list per patient and completed a form with patient characteristics. Nephrologists filled out the Charlson Comorbidity Index. Independent observers clocked the time nurses spent on separate steps of the dialysis for each patient. Dialysis centres were categorised into four types. Data were analysed using regression models. In contrast to other dialysis centres, academic centres needed 14 minutes more care time per patient per dialysis treatment than predicted in the classification model. No patient characteristics were found that influenced this difference. The only patient characteristic that predicted the time required was gender, with more time required to treat women. Gender did not affect the difference between measured and predicted care time. Differences in care burden were observed between academic and other centres, with more time required for treatment in academic centres. Contribution of patient characteristics to the time difference was minimal. The only patient characteristics that predicted care time were previous transplantation, which reduced the time required, and gender, with women requiring more care time. © 2017 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    2005-11-01

    Trauma centres have been shown to reduce the number of preventable deaths from serious injuries. This is due largely to the rapid response of surgeons and health care teams to resuscitate, evaluate, and operate if necessary. Less is known about the effectiveness of trauma centre care on those patients who have not incurred immediate life-threatening problems and may not be as critically injured. The purpose of this study was to review the use of physician and hospital resources for this patient population to determine whether trauma team and trauma centre care is helpful or even needed. This was a retrospective study of consecutive trauma patients (n=1592) admitted from 1998 to 2002 to the trauma service of an urban level I trauma centre and recorded in the hospital trauma registry. Patients were triaged in a tiered response to more or less severely injured. All patients' care was directed by trauma surgeons. Of the 1592 patients, 398 (25%) received a full trauma team response (Class I), 1194 were less seriously injured (Class II). The ISS for the Class I patients was 19+/-18 and for Class II patients 10+/-10. Nineteen percent of Class II patients had an ISS>15. Overall mortality in Class II patients was 2% including 20 unexpected deaths. Four hundred and three Class II patients (34%) had multisystem injuries. Of the Class II patients 423 (35%) were sent to the ICU or OR from the ED, 106 of whom required an immediate operation and 345 required an operation prior to discharge. Complications developed in 129 patients (11%), the majority of which were pulmonary. A large proportion of those patients thought initially to be less severely injured required resources available in a trauma centre, including specialty care, intensive care, and operating room accessibility. Over one-third of these patients had multisystem injuries and almost 20% were considered major trauma, needing prioritisation of care and expertise ideally found in a trauma centre environment

    Neuroectodermal signalling centres induce and pattern many novel vertebrate brain structures but are absent, or divergent, in invertebrate chordates. This has led to the idea that signalling-centre genetic programs were first assembled in stem vertebrates and potentially drove morphological innovations of the brain. 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 (a single gene homologous to vertebrate Fgf8, Fgf17 and Fgf18), 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 that 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. © 2012 Macmillan Publishers Limited.

  3. Teaching clinical skills in developing countries: are clinical skills centres the answer?

    PubMed

    2003-11-01

    There is growing international interest in teaching clinical skills in a variety of contexts, one of which is Clinical Skills Centres. The drivers for change making Skills Centres an important adjunct to ward and ambulatory teaching come both from within and outside medical education. Educationally, self-directed learning is becoming the accepted norm, encouraging students to seek and maximize learning opportunities. There are global changes in health care practice, increased consumerism and increasing student numbers. In some countries, professional recommendations influence what is taught. Increasingly, core skills curricula and outcome objectives are being defined. This explicit definition encourages assessment of the core skills. In turn, all students require equal opportunities to learn how to practise the skills safely and competently. The moves towards interprofessional education make joint learning in a"neutral" setting, like a Clinical Skills Centre, appear particularly attractive. To discuss the potential role of Clinical Skills Centres in skills training in developing countries and to consider alternative options. Many developing countries seek to establish Clinical Skills Centres to ensure effective and reliable skills teaching. However, the model may not be appropriate,because fully equipped Clinical Skills Centres are expensive to set up, staff; and run. They are not the only way to achieve high quality clinical teaching. Suggested options are based on the philosophy and teaching methods successfully developed in Clinical Skills Centres that may fulfil the local needs to achieve low cost and high quality clinical teaching which is reflective of the local health needs and cultural expectations.

    The aim of the study was to compare the antimicrobial resistance pattern of Neisseria gonorrhoeae isolates from urban and rural peripheral health centres and from sexually transmitted disease (STD) clinic attendees. Antimicrobial susceptibility testing of 191 N. gonorrhoeae isolates (165 isolates from STD clinic attendees and 26 from peripheral health centres) was carried out in Delhi, India, using the calibrated dichotomous sensitivity technique for penicillin, tetracycline, ceftriaxone, ciprofloxacin, spectinomycin and nalidixic acid, and minimum inhibitory concentrations were determined using E-test. Penicillin-resistant, ciprofloxacin-resistant, penicillinase-producing N. gonorrhoeae and tetracycline-resistant N. gonorrhoeae strains were higher in STD clinic attendees than in peripheral health centres, probably because of less antibiotic pressure in the peripheral areas. High-level resistance to ciprofloxacin and multiresistant strains were also higher in STD clinic attendees. The present study emphasizes the importance of surveillance of antimicrobial resistance of N. gonorrhoeae in different population subgroups in order to monitor the spread of multiresistant strains and to update the national treatment recommendations.

    To empower patients and improve the quality of care, policy-makers increasingly adopt systems to enhance person-centred care. Although models of person-centredness and patient-centredness vary, respecting the needs and preferences of individuals receiving care is paramount. In Sweden, as in other countries, healthcare providers seek to improve person-centred principles and address gaps in practice. Consequently, researchers at the University of Gothenburg Centre for Person-Centred Care are currently delivering person-centred interventions employing a framework that incorporates three routines. These include eliciting the patient's narrative, agreeing a partnership with shared goals between patient and professional, and safeguarding this through documentation. To explore the barriers and facilitators to the delivery of person-centred care interventions, in different contexts. Qualitative interviews were conducted with a purposeful sample of 18 researchers from seven research studies across contrasting healthcare settings. Interviews were transcribed, translated and thematically analysed, adopting some basic features of grounded theory. The ethical code of conduct was followed and conformed to the ethical guidelines adopted by the Swedish Research Council. Barriers to the implementation of person-centred care covered three themes: traditional practices and structures; sceptical, stereotypical attitudes from professionals; and factors related to the development of person-centred interventions. Facilitators included organisational factors, leadership and training and an enabling attitude and approach by professionals. Trained project managers, patients taking an active role in research and adaptive strategies by researchers all helped person-centred care delivery. At the University of Gothenburg, a model of person-centred care is being initiated and integrated into practice through research. Knowledgeable, well-trained professionals facilitate the routines of narrative

    Nitrogen-vacancy colour centres in diamond can undergo strong, spin-sensitive optical transitions under ambient conditions, which makes them attractive for applications in quantum optics, nanoscale magnetometry and biolabelling. Although nitrogen-vacancy centres have been observed in aggregated detonation nanodiamonds and milled nanodiamonds, they have not been observed in very small isolated nanodiamonds. Here, we report the first direct observation of nitrogen-vacancy centres in discrete 5-nm nanodiamonds at room temperature, including evidence for intermittency in the luminescence (blinking) from the nanodiamonds. We also show that it is possible to control this blinking by modifying the surface of the nanodiamonds.

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

    Ascertainment bias (AB) indicates a bias of an evaluation centre in estimating the prevalence/incidence of a disease due to the specific expertise of the centre. The aim of our study was to evaluate classification of different types of dementia in new cases appearing in secondary and tertiary centres, in order to evidence possible occurrence of AB in the various (secondary to tertiary) dementia centres. To assess the mechanism of AB, the rates of new cases of the different forms of dementia reported by different centres were compared. The centres involved in the study were 11 hospital-based centres including a tertiary centre, located in the University Department of Clinical Neurology. The tertiary centre is endowed with state-of-the-art diagnostic facilities and its scientific production is prominently focused on dementia with Lewy bodies (DLB) thus suggesting the possible occurrence of a bias. Four main categories of dementia were identified: Alzheimer's disease (AD), DLB, fronto-temporal dementia (FTD), vascular dementia (VaD), with other forms in a category apart. The classification rate of new cases of dementia in the tertiary centre was compared with rates reported by secondary centres and rates of recoding were calculated during a follow-up of 2 years. The study classified 2,042 newly diagnosed cases of dementia in a population of 1,370,000 inhabitants of which 315,000 were older than 65. AD was categorized in 48-52 % of cases, DLB in 25-28 %, FTD in 2-4 % and VaD in 17-28 %. During the 2-year follow-up the diagnosis was re-classified in 40 patients (3 %). The rate of recoding was 5 % in the tertiary centre, 2-8 % in referrals from secondary to tertiary centre, 2-10 % in recodings performed in secondary centres and addressed to tertiary centre. Recoding or percentages of new cases of AD or DLB were not different in the comparison between secondary or between secondary and tertiary centres. FTD and VaD were instead significantly recoded.

    To determine: 1) if the three elements of person-centred care (initiating, working and safeguarding the partnership) were present, and 2) to identify evidence of barriers to person-centred care during prolonged weaning from mechanical ventilation. Secondary analysis of semi structured interviews with 19 critical care nurses using theoretical thematic analysis. This study was conducted in three Swedish intensive care units, one in a regional hospital and two in a university hospital. Three themes and nine subthemes related to person-centred care were identified. The three themes included: 1) 'finding a person behind the patient' related to the 'initiating the partnership' phase, 2) 'striving to restore patient́s sense of control' related to 'working the partnership' phase and 3) 'impact of patient involvement' related to 'safeguarding the partnership' phase of person-centred care'. Additionally a further theme 'barriers to person-centred care' was identified. We found evidence of all three person-centred care routines. Barriers to person-centred care comprised of lack team collaboration and resources. Facilitating patients to actively participate in decision-making during the weaning process may optimise weaning outcomes and warrants further research. Copyright © 2017 Elsevier Ltd.

    The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) is the designated hub for drug-related information in the European Union. The organization's role is to provide the European Union (EU) and its Member States with a factual overview of European drug problems and a common information framework to support the drugs debate. In order to achieve its mission, the EMCDDA coordinates and relies on a network of 30 national monitoring centres, the Reitox National Focal Points. The Centre publishes on a wide range of drug-related topics, across epidemiology, interventions, laws and policies. Every November, the EMCDDA publishes its Annual Report, providing a yearly update on the European drug situation, translated into 23 EU languages. In line with its founding regulation, the EMCDDA has a role acting as an interface between the worlds of science and policy. While not a research centre in the formal sense, the results the Centre generates serve as catalysts for new research questions and help to identify priorities. Current challenges facing the agency include continuing to increase scientific standards while maintaining a strong institutional role, as well as supporting European efforts to identify, share and codify best practice in the drugs field. © 2011 EMCDDA.

    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.

    A new centre has been established to provide readily accessible counselling, consultation, and mental health information. People may refer themselves or are recommended to attend by general practitioners or other agencies. The counsellors have varied backgrounds in paramedical or counselling services, and they are supported by psychiatrists. Of a sample of 100 clients, four were referred to one of the team's psychiatrists and 33 visited the centre only once. The centre's staff aim to adopt a flexible approach to the client and his problems, and formal psychiatric categories have not been found useful. Provision is made for people who want to solve their problems by discussion rather than medication and those for whom the existing psychiatric services may have little time to spare. Consequently, the approach adopted by the Isis Centre, whereby many people benefit from psychotherapy yet the psychiatrist deals directly with only a few selected cases, contributes towards meeting the great need for psychiatric services and using the psychiatrist's skills more effectively.

    We demonstrate that (F+2)AH centres of KCl may be obtained from crystals doped with K{2}CO{3} and NaCl, grown by the Czochralski method in open atmosphere. The optical properties of (F+2)AH centres thus produced are exactly the same as those of (F+2)AH centres prepared by the usual technique, which involves superoxide doping and a controlled atmosphere. Nous montrons que les centres (F+2)AH de KCl peuvent être obtenus à partir de cristaux dopés par K{2}CO{3} et NaCl, fabriqués par la méthode de Czochralski à l'air libre. Les propriétés optiques des centres (F+2)AH ainsi produits sont exactement les mêmes que celles des centres (F+2)AH préparés par la technique habituelle, qui comporte le dopage par un superoxyde et l'emploi d'une atmosphère contrôlée.

    The number of patients with a diagnosis of cancer is alarming: according to new figures from the Robert Koch Institute about 435 000 patients are diagnosed annually in Germany. 210 000 patients die annually of this diagnosis. Even if no significant progress in prevention has been achieved, in 2020 about 25 % more cases will be diagnosed. In the last two decades it has become established that an interdisciplinary treatment of tumour patients is necessary because the variety of different treatment options depending on an individual person cannot be mastered by one physician. The goal of the centres and certification is to establish a very concentrated expertise in large case numbers and quality-assured transparent treatment. The central requirement of a maximum-care centre is thus to enable communication under appropriate conditions. Promoting not only the space requirements, centre must also develop a treatment corridor and is responsible for further education. Additionally an oncology centre has a goal in communications, namely, to offer a treatment option for all patients in each stage of the disease, and to incorporate cancer patients in clinical trials. © Georg Thieme Verlag KG Stuttgart · New York.

    Examine the nutritional quality of food and beverages consumed across a sample of community aquatic and recreation centres in metropolitan Melbourne, Australia. Interviewer-administered surveys of randomly selected patrons attending four aquatic and recreation centres were conducted to ascertain food and beverage items consumed over two data collection periods (May-June 2014, January-February 2015). We selected centres in and around metropolitan Melbourne with a sit-down cafeteria and children's swimming classes. We classified items by government nutrient profiling guidelines; 'green' (best choice), 'amber' (choose carefully) or 'red' (limit). A total of 2,326 surveys were conducted (response rate 63%). Thirty-five per cent of surveyed patrons consumed food or beverages while at the centre; 54% of patrons purchased from the café and 61% brought items to the centre. More than half the food consumed from the café was 'red', increasing to 92% for children. One in five children visiting the centre consumed a 'red' item bought from the centre café. The nutritional quality of food and beverages consumed at recreation centres was generally poor, with the on-site cafés providing the majority of discretionary items consumed. Implications for public health: Community aquatic and recreation centres provide an opportunity to promote healthy eating by increasing the provision of healthy options and limiting discretionary food and drink items. © 2017 The Authors.
