    Full Text Available This number of the EAI Transactions on Serious Games is dedicated to a set of ongoing research and development projects in this area. The selected articles represent very well the diversity of approaches, contexts and objectives that foster and render highly dynamic this area of study. In Europe, several funding programmes like the 7th Framework Programme, the Lifelong Learning Programme and the most recent Horizon 2020 made specific provisions to support Serious Games projects. At the same time, enterprises are recognizing more and more the potential of SG to train and to motivate their workforce and are therefore joining forces with the academy and SG producers to design specific SG. Serious Games became one of the most interesting “places to be” due to its growing scientific and practitioner community. We can say that the motivating and addictive character of games has been successfully transmitted to the research and development of Serious Games.

    A wide range of optics issues for energy recovery linac (ERL)-based projects are illustrated through the presentation of ongoing projects covering both light sources, at Cornell and Daresbury and high energy and nuclear physics accelerators at the Brookhaven National Laboratory. This presented range of projects demonstrates how the different designs teams see the challenges of studying and solving optics issues for their particular project's ERLs, with studies appropriate to the stage of maturity of the project. Finally, as an illustration of the complexity and detail behind a single aspect of ERL optics design we present an overview of the highly important generic topic of longitudinal phase space evolution in ERLs

    The aim of this study was to present the development, structure and results of a database on planned and ongoing health technology assessment (HTA) projects (POP Database) in Europe. The POP Database (POP DB) was set up in an iterative process from a basic Excel sheet to a multifunctional electronic online database. The functionalities, such as the search terminology, the procedures to fill and update the database, the access rules to enter the database, as well as the maintenance roles, were defined in a multistep participatory feedback loop with EUnetHTA Partners. The POP Database has become an online database that hosts not only the titles and MeSH categorizations, but also some basic information on status and contact details about the listed projects of EUnetHTA Partners. Currently, it stores more than 1,200 planned, ongoing or recently published projects of forty-three EUnetHTA Partners from twenty-four countries. Because the POP Database aims to facilitate collaboration, it also provides a matching system to assist in identifying similar projects. Overall, more than 10 percent of the projects in the database are identical both in terms of pathology (indication or disease) and technology (drug, medical device, intervention). In addition, approximately 30 percent of the projects are similar, meaning that they have at least some overlap in content. Although the POP DB is successful concerning regular updates of most national HTA agencies within EUnetHTA, little is known about its actual effects on collaborations in Europe. Moreover, many non-nationally nominated HTA producing agencies neither have access to the POP DB nor can share their projects.

    Full text of publication follows: The nuclear industry in the U.S. faced many construction quality and design issues in the 1970's and 1980's. In 1984, the NRC issued NUREG-1055, 'Improving Quality and the Assurance of Quality in the Design and Construction of Nuclear Power Plants,' to document the lessons learned from nuclear power plant (NPP) construction in the U.S. In recent years, several countries have begun either planning for or actually constructing new NPPs. For instance, in the U.S., the nuclear industry has submitted several combined license and design certification applications to the NRC for licensing reviews and approval to build 30+ new NPP units. Latest construction experience from countries that are currently building new NPPs indicate that these countries are dealing with challenges that are similar to those issues that caused major quality assurance problems, delays, or even termination of several projects in U.S. in the 70's and 80's. The U.S. NRC is pro-actively taking measures to improve its regulatory programs as well as construction oversight activities before new NPPs construction begin in the U.S. In late 2007, the U.S. NRC's Office of New Reactors established a construction experience program (ConE) to obtain and evaluate construction and operating experience events and to identify the lessons learned from these events. In March 2009, the NRC published an Office Instruction to provide a process for incorporating the lessons learned and insights from the design, construction, and operation of the international and domestic NPPs into the licensing reviews, inspections, and construction of new reactors in the U.S. Additionally, the ConE program staff developed a Web-enabled database to store, manage, and make construction experience information available to all NRC technical reviewers as well as inspectors. Because this database contains information from other countries' regulators that are considered

    Sequencing of microbial genomes is important because of microbial-carrying antibiotic and pathogenetic activities. However, even with the help of new assembling software, finishing a whole genome is a time-consuming task. In most bacteria, pathogenetic or antibiotic genes are carried in genomic islands. Therefore, a quick genomic island (GI) prediction method is useful for ongoing sequencing genomes. In this work, we built a Web server called GI-POP (http://gipop.life.nthu.edu.tw) which integrates a sequence assembling tool, a functional annotation pipeline, and a high-performance GI predicting module, in a support vector machine (SVM)-based method called genomic island genomic profile scanning (GI-GPS). The draft genomes of the ongoing genome projects in contigs or scaffolds can be submitted to our Web server, and it provides the functional annotation and highly probable GI-predicting results. GI-POP is a comprehensive annotation Web server designed for ongoing genome project analysis. Researchers can perform annotation and obtain pre-analytic information include possible GIs, coding/non-coding sequences and functional analysis from their draft genomes. This pre-analytic system can provide useful information for finishing a genome sequencing project. Copyright © 2012 Elsevier B.V. All rights reserved.

  12. Radionuclide retardation project at GTS - An overview of lessons learned and ongoing experiments

    Moeri, A.

    2001-01-01

    The joint Nagra/JNC Radionuclide Migration Programme has now been ongoing for more than 15 years in Nagra's Grimsel Test Site (GTS). The main aim of the programme has been the direct testing of radionuclide transport models in as realistic a manner as possible. The understanding and modelling of both the processes and the structures influencing radionuclide transport/retardation in fractured granitic host rocks have matured as has the experimental technology, which has contributed to develop confidence in the applicability of the underlying research models in a repository performance assessment. In this paper, three in situ experiments which were carried out in a discrete granitic shear zone are briefly presented: The Migration Experiment (MI), the Excavation Experiment (EP) and the ongoing Colloid and Radionuclide Retardation Experiment (CRR). Each project expanded on the experimental experience and research results from the preceding experiment. MI provided a sound data base of in situ tracer breakthrough curves which was used to derive relevant transport parameters by inverse modelling in order to enhance the capability for predictive modelling of tracer transport in a granitic shear zone. The Excavation Project (EP) then focussed on the excavation of the dipole flow field in order to describe the flow paths within the shear zone dipole and the retardation behaviour of sorbing radionuclides that are relevant to post-closure safety. The ongoing CRR experiment actually investigates the influence of bentonite colloids on the radionuclide transport behaviour through a fractured granitic host rock. Again, the experience in planning and handling of complex tracer field experiments gained in the proceeding experiments will be availed. The methodology adopted for the geological and hydrological characterisation of water-conducting features and the simplification of this characterisation for modelling purposes proved to be indeed effective on the modelling of

    PURPOSE. Although in the last decades primary care research has evolved with great success, there is a growing need to prioritize the topics given the limited resources available. Therefore, we constructed a nationwide database of ongoing primary care research projects in the Netherlands, and we assessed if the distribution of research topics matched with primary care practice. We conducted a survey among the main primary care research centres in the Netherlands and gathered details of all ongoing primary care research projects. We classified the projects according to research topic, relation to professional guidelines and knowledge deficits, collaborative partners and funding source. Subsequently, we compared the frequency distribution of clinical topics of research projects to the prevalence of problems in primary care practice. We identified 296 ongoing primary care research projects from 11 research centres. Most projects were designed as randomized controlled trial (35%) or observational cohort (34%), and government funded mostly (60%). Thematically, most research projects addressed chronic diseases, mainly cardiovascular risk management (8%), depressive disorders (8%) and diabetes mellitus (7%). One-fifth of the projects was related to defined knowledge deficits in primary care guidelines. From a clinical primary care perspective, research projects on dermatological problems were significantly underrepresented (P = 0.01). This survey of ongoing projects demonstrates that primary care research has a firm basis in the Netherlands, with a strong focus on chronic disease. The fit with primary care practice can improve, and future research should address knowledge deficits in professional guidelines more.

  16. The Control Room Upgrade in Oskarshamn 2 Modernization Project Lesson Learned from Ongoing Human Factor design

    2011-01-01

    Due to recent changes in Swedish commercial nuclear safety system requirements, OKG decided to make the changes required by the new safety requirements, apply for a 30-year license extension, and to concurrently make changes for a major power uprate; this project is called the Plant Life Extension project (PLEX). It was decided, in addition to several plant modifications, to re build the old control room to a new modern screen-based control room located in the same space as the old one, and with the same number of operators. This paper explains the approach taken when modernizing the control room as a part of the Oskarshamn 2 Modernization project PLEX, the results, and the lessons learned from this ongoing work. The combination of changes results in a modernization project that is expected to increase output power by approximately 50 MWe through increased efficiency and to result in an increase in thermal power from 1800 MWt to 2300 MWt (28%) and electrical power from 620 MWe to 840 MWe due to the power uprate. The license to operate OKG2 expires in 2012 The PLEX project is one of the most ambitious nuclear power plant modernization projects ever implemented, world-wide. The application of human factors engineering (HFE) and control room and HSI design is a complex challenge. The original main control room from 1975 in Oskarshamn 2, was quite compact and provided a fairly good overview of the process. New requirements for enhanced safety and other design changes in the process systems and instrumentation led to a step-wise installation of new information and control equipment in the control room. Since the control room was quite limited in space, the control room grew larger, and the new equipment was installed farther away from the operator workplaces into an adjacent control room. This was even the case for the new safety systems. These systems were functioning well separately as such, but in some cases their interfaces were inconsistent, leading to increased

  17. Using an Ongoing Study of Terrestrial Plant Response to Ultraviolet Radiation in Project ALERT

    1998-01-01

    The ALERT (Augmented Learning Environment for Renewable Teaching) Project is a cooperative California-based program with two main partners: California State University (CSU) geoscience and education departments and two NASA Centers, the Jet Propulsion Laboratory (JPL) in Pasadena and the Ames Research Center (ARC) in Mountain View. This paper presents an example of how a NASA research effort can be used in the undergraduate classroom. A study, now in the fourth year, subjects test plants to exposures of varying solar ultraviolet (UV) radiation (280 - 340 nm); a full solar UV exposure, a solar UV exposure less about 14% of ambient UV flux, and a UV-blocked regime. This experiment is simple in that only modest amounts of expense are required yet it is elegant since only one variable, UV-flux is involved. The experiment lends itself to teaching several of the Earth Sciences because it uses information from botany, taxonomy, and ecology. Aspects of physics are inherent in the study since portions of the electromagnetic spectrum are studied. Further, since only one of many variables are manipulated, UV flux, the study demonstrates how the scientific method is used in formulating and testing hypotheses. Based on the ALERT experience this summer, this study will be implemented at a CSU campus with the expectation that it will serve as a pedagogical tool and where it will involve students in actual research.

  18. Multiple Clustering Views via Constrained Projections

    DEFF Research Database (Denmark)

    Dang, Xuan-Hong; Assent, Ira; Bailey, James

    2012-01-01

    Clustering, the grouping of data based on mutual similarity, is often used as one of principal tools to analyze and understand data. Unfortunately, most conventional techniques aim at finding only a single clustering over the data. For many practical applications, especially those being described...... in high dimensional data, it is common to see that the data can be grouped into different yet meaningful ways. This gives rise to the recently emerging research area of discovering alternative clusterings. In this preliminary work, we propose a novel framework to generate multiple clustering views....... The framework relies on a constrained data projection approach by which we ensure that a novel alternative clustering being found is not only qualitatively strong but also distinctively different from a reference clustering solution. We demonstrate the potential of the proposed framework using both synthetic...

    Full text: In order to support the development of an efficient and validated response to counteract illicit trafficking of nuclear materials in the EU, the candidate countries and some CIS countries, ITU is currently executing a series of dedicated projects with the Candidate Countries to the European Union, based upon the experience gained in previous Phare and Tacis projects. Following the recommendations of the International Technical Working Group (ITWG), the objectives of the projects are: assessment of the national situation during a fact-finding mission in the country; technical upgrade and/or training related to the categorisation of nuclear material on the spot and assistance for the identification of seized nuclear material, through joint analysis at ITU; implementation of the recommended Model Action Plan in the form of a national handbook called RITNUM (Response to Illicit Trafficking of NUclear Material); validation of the national Model Action Plan by the organisation of a demonstration exercise in the country involving all the identified services in the field. After a kick-off meeting held in Karlsruhe in November 2000 and attended by two participants of each country, 5 fact-finding missions have been already performed (Romania, Slovenia and the three Baltic States). A general meeting with all the involved parties (Customs, Police, Intelligence services. Health Physics, Nuclear reference laboratory...) was organised to describe the procedure of the integrated response and the national needs were assessed. The corresponding training sessions are planed in January 2002 at ITU for three participants for each country (Customs and Police officer and high level scientist dealing with nuclear measurements). This training session will be organised and supported by IAEA which have a common interest through its Regional Program on Combating Illicit Trafficking (RER60). This joint action will be extended to other eastern countries (ex. Belarus) on IAEA request

    Education and awardness on sciences and on natural phenomena is a concern of both researchers teachers with many social issues. A well-defined frame is critical for interaction and collaboration and should be illustrated on key examples. Observing and analysing seismic data is one of these examples because earthquakes with strong implications in our industrial society attract young people and because different area around the world may share observations, informations and activities concerning earthquakes both local if there is any and global if they are strong enough. In order to focus on doing science and on analysing data, one has to reduce efforts for collecting data (if not hiding it) while having them measuring the same physical quantities and in a format readable by different available softwares. We shall illustrate solutions we have developped in an interaction between colleges and laboratories with different specific cultural approaches of European countries. Activities ranging from metrology to interpretation and presentation should improve scientific behaviour of students as well as increase their understanding of the Earth. We shall illustrate through the diversity of European initiatives that we share common objectives. Systematic use of new technologies for collecting numbers (measurements) and for crunching them (interpretation) will retain the attention of the students and will hopefully attrack them to Sciences related to the Earth. In the present on-going process, we shall show the necessity for an European organisation and support inside the more global international interaction. Such initiatives focus on scientific training of people for making more award citizens of our society.

    BENIPA (Bentonite Barriers in Integrated Performance Assessment) is a research project, within the Fifth Framework Programme of the European Union, which was started on September 2000 and is has a duration of 36 months. The overall objective of BENIPA is to assess the state of the art in the treatment of bentonite barriers in Integrated Performance Assessment, evaluating the capacity and consistency of methods and data available to convincingly justify the capacity of bentonite to perform their assigned safety functions. During the first part of the project different bentonite barrier concepts have been reviewed and four reference cases have been defined for the modelling work in the project. FEP's Databases have been created and the scientific and technical bases for the analysis of bentonite barriers have been reviewed. In the second part of the project. as a step previous to modelling, an analysis of models for the mechanical, hydrological, thermal and chemical conditions is carried out, along with a review of the needs in input data. In BENIPA, calculations at process and integrated level are currently being performed among different codes to check consistency and sufficiency or complementarity for fulfilling the needs of performance assessment. However, since it is too early to present some of the results or even the individual contributions of the partners, the modelling and calculations being currently carried out by ENRESA will be advanced, just as a representative example of the work going on. This paper summarises the work already done in BENIPA and provides with illustrations of the modelling work consisting of the approach followed by ENRESA in applying three codes: CODE-BRIGHT, CORE 2D and GOLDSIM. The processes considered, simplifications adopted, limitations imposed and preliminary findings of the work are mentioned along. (author)

    1981-08-07

    To assist the Department of Energy, Office of Fuels Conversion (OFC), in implementing the synthetic fuel exemption under the Powerplant and Industrial Fuel Use Act (FUA) of 1978, Resource Consulting Group, Inc. (RCG), has developed a procedure for matching prospective users and producers of synthetic fuel. The matching procedure, which involves a hierarchical screening process, is designed to assist OFC in: locating a supplier for a firm that wishes to obtain a synthetic fuel exemption; determining whether the fuel supplier proposed by a petitioner is technically and economically capable of meeting the petitioner's needs; and assisting the Synthetic Fuels Corporation or a synthetic fuel supplier in evaluating potential markets for synthetic fuel production. A data base is provided in this appendix on proposed and ongoing synthetic fuel production projects to be used in applying the screening procedure. The data base encompasses a total of 212 projects in the seven production technologies.

    FASTBUS is a modular data and control bus and mechanical packaging standard currently under development. It is being funded by the United States Department of Energy and fully supported by the European ESONE Committee. FASTBUS is being designed to meet the high-speed data acquisition and parallel and distributed processing requirements of the next generation of large-scale physics experiments. It is a multiprocessor system with multiple bus segments which operate independently but link together for passing data. It operates asynchronously to accommodate very high and very low speed devices over long and short paths, using handshake protocols for reliability. It can also operate synchronously without handshakes for transfer of data blocks at maximum speed. The motivation for developing FASTBUS, its goals, history and organizational structure are summarized. Its features such as bus protocols, sparse data scan capabilities, power supplies and mechanics, bus segmentation and parallel processing structures, etc. are described. European and United States systems being proposed or built using FASTBUS along with hardware and software projects to aid in the standard or system development are discussed. The paper concludes by reviewing the present state of and development schedules for the FASTBUS standard. (orig.)

    2016-04-01

    Full Text Available This article discusses the issue of unique therapeutic projects within the mental health services built in the Brazilian psychiatric reform process. Starting from the concepts that have gained strength in both the psychiatric reform as in the collective health, this study proposes that current notions of the therapeutic project still are influenced by biological, psychological or social paradigms that simplify the complexity of the experience suffered by the subjects. Despite therapeutic projects are an essential achievement for the qualification of mental health care, it is still necessary to produce an epistemological rupture in the relationship with mental suffering so that they can achieve the greatest potential for transformation. Therefore, the article suggests that the practice of therapeutic projects should hold discussions with the reality of users life of and their relationships in the territories of existence, to transform the relations of power and knowledge that reproduce the subjects annulment. Thus, it is possible to dialogue with the complexity of the mental suffering experience, producing changes in the scenes that produce it.

    Full text: The Electron Microscope Unit (EMU) at the University of Sydney has recently installed a new JEOL 3000F Field Emission Gun TEM. With a point resolution of 1.95 Angstroms, it is the ideal tool for high resolution imaging. The microscope also has an Oxford INCA EDS system and GATAN GIF attached, and with an incident probe of diameter ≥0.5nm. As such, it is an excellent tool for microanalysis and in conjunction with a VGSTEM, these facilities are ideal for a large variety of materials microscopy and microanalysis at high resolution. These facilities are also central to the outreach work of the EMU'S Key Centre and add important capability to the Nanostructural Analysis Network Organisation (NANO) the new Australian Major National Research Facility in characterisation. In this poster we will be presenting results from a number of ongoing projects which demonstrate some of the capabilities of both microscopes, including high resolution imaging, phase analysis in Al alloys, compositional gradients in novel glass optical fibres, alternative mechanisms for the formation of misfit dislocation in quantum dots and compositional analysis in quantum well structures.

    2004-01-01

    The IAEA General Conference (2000) invited 'all interested Member States to combine their efforts under the aegis of the IAEA in considering the issues of the nuclear fuel cycle, in particular by examining innovative and proliferation-resistant nuclear technology'. In response to this invitation, the IAEA initiated the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO). The overall objectives of INPRO are to help to ensure that nuclear energy is available to contribute in fulfilling energy needs in the 21. century in a sustainable manner, and to bring together both technology holders and technology users to consider jointly the international and national actions required to achieve desired innovations in nuclear reactors and fuel cycles. In order to fulfil these objectives, the first phase of INPRO dealt with the development of a methodology to assess and compare the performance of innovative nuclear energy systems.

    Synopsis:This essay argues that the classic view has to be updated to meet the new demands. It is found out that the scientific manage-ment believes that there are a few essential roles of managers,including planning,organizing,leading,and controlling. There are many impor-tant aspects which lead to the complexity of the modern project management such as globalization and technology. There are many things that are not compatible between the current projects and the traditional theory. It is also considerable to realize that sometimes scholars disagree with each other about the prevalence of complicated projects. However,even if the classic project management theory is useful in certain cases, there is no doubt that such theory demands significant improvements to better suit the current world. Therefore,it is significant that the classic project management theory be upgraded. In order to improve the performances of the project management,it is recommended that stakeholder theory is promoted,decentralized decision making is allowed,and adoption of new technology is recommended.

    The western Mediterranean tectonic system consists of the Betic Mountains in southern Spain and the Rif Mountains in northern Morocco curved around the back-arc extensional Alboran basin. Multiple tectonic models have been developed to explain the coeval compressional and extensional tectonic processes that have affected the western Mediterranean since the Oligocene. In order to provide constraints on these evolutionary models, we use Ps teleseismic receiver functions (RF), thermobarometric analyses of post-Oligocene basalts, and previous teleseismic tomography images to investigate the lithospheric structure of the region. Ps RFs were calculated using seismic data from 239 broadband seismic stations in southern Iberia and northern Morocco and thermobarometric analysis was performed on 19 volcanic samples distributed throughout the region. The RF images reveal a highly variable Moho depth (˜25 to ˜55 km), as well as a strong positive, sub-Moho horizon between ˜45 and ˜80 km depth beneath the central Betic and Rif Mountains, which we interpret to be the top of the previously imaged Alboran Sea slab. Thermobarometric constraints from magmas in the eastern Betics and Rif indicate mantle melting depths between 40 and 60 km, typical of melting depths beneath mid-oceanic ridges where little to no lithosphere exists. Together, the RF and thermobarometric data suggest ongoing and recent slab detachment resulting from delamination of the continental lithosphere.

    Full Text Available The purpose of this study was to find out the students’views about the innovations brought about by FATIH Project. The research data were collected via field notes, in-class observations made in 10 class hours and focus group interviews held with 45 students participating in the study on voluntary basis from five state schools located in the cities of Ankara, Karaman, Mersin (2 and Uşak. Within the scope of the study the data were analyzed with the content analysis method. It was found out the innovations brought about by FATIH Project led to positive changes in students’ interest and willingness in classes, their achievement levels, their motivations, their pace of learning, their technology use and research skills, permanency in their learning and their self-confidence. The students reported that the negative changes included distraction of students’ attention to classes, limitation in face-to-face communication with the teacher, the slowing pace of teaching, time-taking classes, confidence problems, the teacher’s increasing desire to control students and difficulty in class-management.It was also revealed that use of tablets for a long time resulted in eye diseases and headaches and that the project helped the students instantly reach the information they needed, contributed to their motivation in learning yet had negative influence on their socialization. It was found that the students felt themselves privileged as they were involved in the project; that they were pleased as the classes were taught in a more entertaining manner; and that inefficient content and interaction problems between the interactive whiteboard and tablet computers were considered to be negative consequences of the innovations brought about by the project.

  14. Update: Health Status of Iranian Victims of Chemical Weapons / Ongoing Research Projects Addressing CW Health Effects in Iran

    Khateri, S.

    2007-01-01

    Use of chemical weapons against Iran during the 1980s was a horrifying epic in the annals of modern warfare, inflicting enormous suffering during the conflict that continues to the present day in the form of latent illness among survivors. Surviving victims suffer from a diverse range of chronic illnesses placing an enormous strain on the nation's medical infrastructure. To define the scope of this problem, the National Organization for Veteran's Affairs (Janbazan) established a subsidiary research department called Janbazan Medical and Engineering Research Center (JMERC). Beginning in 2000 JMERC has conducted epidemiological, clinical and basic scientific studies to characterize disease among chemical attack survivors and develop new therapeutic strategies. The primary JMERC mission has been to identify where resources may be allocated so as to most effectively treat patients with the greatest need - requiring a comprehensive picture of the major medical problems among this population. Accordingly, JMERC's initial task was to define the nature and distribution of serious chronic illness among CW survivors. Therefore epidemiological studies in CW-exposed Iranian populations are currently underway. Ultimately these studies will allow management of illness among CW-exposed populations that is both compassionate and cost-effective. A summary of the above mentioned research projects will be reported in this article. (author)

    2012-11-01

    This paper, part one of a two paper report, describes key aspects of the research context of an ongoing practice development project, conducted on two UK sites. The paper begins with a discussion of the project's origins within a community of people working in the recovery paradigm, including the contributory strand of the first author's recovery and survivor writing. The discussion then turns to three inter-related areas within which the research component sits and which provide it with philosophical, theoretical and conceptual coherence. Each area will be unpacked and its significance explained. This will provide a platform for discussing the focus, methodology and methods of the research, and related assumptions governing both data collection and analysis. The paper concludes with a research commitment to a mental health nursing practice allied to recovery as narrative healing. Links are made to the second paper which describes the context and specifics of a Writing for Recovery project for users, survivors and carers. This shares with, and builds on, the overall project's research context and its assumptions. © 2012 Blackwell Publishing.

    One of the major aims in the economic management of a nuclear power project is the completion of the project on scheduled time, at preditermined cost and technical performance in accordance with pre-established goals. The achievement of these goals depends, to the major extent, on the adequacy and accuracy of the project plan. The highest possibilities to save money, minimize delivery time, secure good performance are given during the periode of project planning. During project implementation the project management only should direct his activities for the realization of the pre-elaborated project plan. (orig./FW) [de

    The 4-year JASMIN collaborative project (Joint Advanced Severe accidents Modelling and Integration for Na-cooled fast reactors), started in Dec.2011 in the frame of the 7. Framework Programme of the European Commission. It aims at developing a new European simulation code, ASTEC-Na, dealing with the primary phase of SFR core disruptive accidents. The development of a new code, based on a robust advanced simulation tool and able to encompass the in-vessel and in-containment phenomena occurring during a severe accident is indeed of utmost interest for advanced and innovative future SFRs for which an enhanced safety level will be required. This code, based on the ASTEC European code system developed by IRSN and GRS for severe accidents in water-cooled reactors, is progressively integrating and capitalizing the state-of-the-art knowledge of SFR accidents through physical model improvement or development of new ones. New models are assessed on in-pile (CABRI, SCARABEE etc...) and out-of pile experiments conducted during the 70's-80's and code-o-code benchmarking with current accident simulation tools for SFRs is also conducted. During the 2 and a half first years of the project, model specifications and developments were conducted and the validation test matrix was built. The first version of ASTEC-Na available in early 2014 already includes a thermal-hydraulics module able to simulate single and two-phase sodium flow conditions, a zero point neutronic model with simple definition of channel and axial dependences of reactivity feedbacks and models derived from SCANAIR IRSN code for simulating fuel pin thermo-mechanical behaviour and fission gas release/retention. Meanwhile, models have been developed in the source term area for in-containment particle generation and particle chemical transformation, but their implementation is still to be done. As a first validation step, the ASTEC-Na calculations were satisfactorily compared to thermal-hydraulics experimental

    Zika virus belongs to the genus Flavivirus of the family Flaviviridae; it is transmitted to humans primarily through the bite of an infected Aedes species mosquito (e.g., Ae. aegypti and Ae. albopictus) (1). Zika virus has been identified as a cause of congenital microcephaly and other serious brain defects (2). As of June 30, 2016, CDC had issued travel notices for 49 countries and U.S. territories across much of the Western hemisphere (3), including Brazil, where the 2016 Olympic and Paralympic Games (Games of the XXXI Olympiad, also known as Rio 2016; Games) will be hosted in Rio de Janeiro in August and September 2016. During the Games, mosquito-borne Zika virus transmission is expected to be low because August and September are winter months in Brazil, when cooler and drier weather typically reduces mosquito populations (4). CDC conducted a risk assessment to predict those countries susceptible to ongoing Zika virus transmission resulting from introduction by a single traveler to the Games. Whereas all countries are at risk for travel-associated importation of Zika virus, CDC estimated that 19 countries currently not reporting Zika outbreaks have the environmental conditions and population susceptibility to sustain mosquito-borne transmission of Zika virus if a case were imported from infection at the Games. For 15 of these 19 countries, travel to Rio de Janeiro during the Games is not estimated to increase substantially the level of risk above that incurred by the usual aviation travel baseline for these countries. The remaining four countries, Chad, Djibouti, Eritrea, and Yemen, are unique in that they do not have a substantial number of travelers to any country with local Zika virus transmission, except for anticipated travel to the Games. These four countries will be represented by a projected, combined total of 19 athletes (plus a projected delegation of about 60 persons), a tiny fraction of the 350,000-500,000 visitors expected at the Games.* Overall

    This paper explores how theories of the planning fallacy and the outside view may be used to conduct quality control and due diligence in project management. First, a much-neglected issue in project management is identified, namely that the front-end estimates of costs and benefits--used in the business cases, cost-benefit analyses, and social and environmental impact assessments that typically support decisions on projects--are typically significantly different from actual ex post costs and ...

  9. Development of a volumetric projection technique for the digital evaluation of field of view.

    Science.gov (United States)

    Marshall, Russell; Summerskill, Stephen; Cook, Sharon

    2013-01-01

    Current regulations for field of view requirements in road vehicles are defined by 2D areas projected on the ground plane. This paper discusses the development of a new software-based volumetric field of view projection tool and its implementation within an existing digital human modelling system. In addition, the exploitation of this new tool is highlighted through its use in a UK Department for Transport funded research project exploring the current concerns with driver vision. Focusing specifically on rearwards visibility in small and medium passenger vehicles, the volumetric approach is shown to provide a number of distinct advantages. The ability to explore multiple projections of both direct vision (through windows) and indirect vision (through mirrors) provides a greater understanding of the field of view environment afforded to the driver whilst still maintaining compatibility with the 2D projections of the regulatory standards. Field of view requirements for drivers of road vehicles are defined by simplified 2D areas projected onto the ground plane. However, driver vision is a complex 3D problem. This paper presents the development of a new software-based 3D volumetric projection technique and its implementation in the evaluation of driver vision in small- and medium-sized passenger vehicles.

  10. ADVERTISEMENTS FOR ICT PROJECT MANAGERS SHOW DIVERSITY BETWEEN SWEDISH EMPLOYERS’ AND PROJECT MANAGEMENT ASSOCIATIONS’ VIEWS OF PM CERTIFICATIONS

    Directory of Open Access Journals (Sweden)

    Siw Lundqvist

    2014-05-01

    Full Text Available Appointing ICT project managers is a delicate issue for management; not least since ICT projects are known to be unsuccessful in delivering the required product in time and on budget. Hence, it is even more important to find the “right” individual for the job. According to project management associations, certification in project management is a prerequisite for a project manager’s successful career. The appreciation of project management certifications among Swedish employers was studied using data collected from job advertisements for ICT project managers during four years (2010-2013. Judged on how the advertisements were worded the result indicates surprisingly low interest from the employers’ side, which conflicts with the project management associations statements about the certifications’ indispensable value for successful projects. Furthermore, it conflicts with a common understanding of certifications as essential for appointment as a project manager. The findings identify a possible gap between PM associations’ and employers’ views regarding the certifications’ value, and highlight the necessity of seriously considering whether it is worthwhile for the individuals to strive for, and for the organizations to promote certification, since it is costly in both time, effort and money.

  14. Is cardiac resynchronization therapy an option in heart failure patients with preserved ejection fraction? Justification for the ongoing KaRen project.

    2010-01-01

    The relevance of electrical and mechanical dyssynchrony has been demonstrated in heart failure with reduced ejection fraction. Preserved ejection fraction is present in as many as 50% of patients with chronic heart failure. Recent small studies suggest that both electrical and mechanical left ventricular dyssynchrony are sometimes present in patients with heart failure and preserved ejection fraction (HFPEF). These data remain controversial and a robust validation of this hypothesis has to be achieved. In the present paper, we review in detail the concepts and try to justify the ongoing KaRen registry. This is a prospective, multicentre, international, observational study to characterize the prevalence of electrical or mechanical dyssynchrony in HFPEF and the resultant effect on prognosis. Patients are enrolled currently at the time of an acute congestive episode. The diagnosis of HFPEF is made according to clinical data, natriuretic peptides and echocardiography for the measurement of ejection fraction. Once stabilized, patients return for a hospital check-up. They undergo clinical and biological evaluation, electrocardiography and Doppler echocardiography. Thereafter, patients are followed every six months, for at least 18 months for mortality, and heart failure-related and non-cardiovascular hospitalizations. KaRen aims to characterize electrical and mechanical dyssynchrony and to assess its prognostic impact in HFPEF. The results may improve our understanding of HFPEF and generate answers to the question of whether or not dyssynchrony could be a target for cardiac resynchronization therapy in HFPEF.

  15. The prevalence of speeding and drunk driving in two cities in China: a mid project evaluation of ongoing road safety interventions.

    Bhalla, Kavi; Li, Qingfeng; Duan, Leilen; Wang, Yuan; Bishai, David; Hyder, Adnan A

    2013-12-01

    Road traffic crashes in China kill in excess of 250,000 people annually, more than any other country in the world. They are the fourth leading cause of premature death in the country and are responsible for 2.4% of the burden of non-fatal health loss in the country. Interventions to curb speeding and drunk driving are being implemented in the cities of Suzhou and Dalian since late 2010. We evaluated the ongoing effect of these activities through five roadside surveys, seven rounds of observational studies, and analysis of crash statistics in the two cities. We find that thus far, the prevalence of speeding has not reduced in either city with the notable exception of one site in Dalian, where the percentage of speeding vehicles declined from nearly 70% to below 10% after an interval-based speed enforcement system was installed. The broader deployment of such speed control technologies across China and other countries should be explored. Roadside alcohol testing suggests that prevalence of drunk driving (i.e. BAC >20 mg%) declined from 6.4% to 0.5% in Suzhou and from 1.7% to 0.7% in Dalian during the monitored time period. However, the measured prevalence rates are very low and should be validated against estimates based on hospital studies. Roadside interviews suggest that the population of both cities is already highly sensitized to the risks associated with drunk driving and speeding. Crash statistics from the two cities do not show appreciable declines in injuries and fatalities as yet. However, the possibility of substantial underreporting in crash statistics sourced from traffic police poses a severe threat to monitoring progress towards road safety in Suzhou, Dalian and across China. There is an urgent need for China to invest in a reliable road traffic injury surveillance system that can provide information for describing key risk factors, evaluating the impact of safety policies, and benchmarking achievements.

  17. ANALYSIS OF FORECASTING METHODS FROM THE POINT OF VIEW OF EARLY WARNING CONCEPT IN PROJECT MANAGEMENT

    Directory of Open Access Journals (Sweden)

    Florin POPESCU

    2017-12-01

    Full Text Available Early warning system (EWS based on a reliable forecasting process has become a critical component of the management of large complex industrial projects in the globalized transnational environment. The purpose of this research is to critically analyze the forecasting methods from the point of view of early warning, choosing those useful for the construction of EWS. This research addresses complementary techniques, using Bayesian Networks, which addresses both uncertainties and causality in project planning and execution, with the goal of generating early warning signals for project managers. Even though Bayesian networks have been widely used in a range of decision-support applications, their application as early warning systems for project management is still new.

    As one of popular immersive Virtual Reality (VR) systems, stereoscopic cave automatic virtual environment (CAVE) system is typically consisted of 4 to 6 3m-by-3m sides of a room made of rear-projected screens. While many endeavors have been made to reduce the size of the projection-based CAVE system, the issue of asthenopia caused by lengthy exposure to stereoscopic images in such CAVE with a close viewing distance was seldom tangled. In this paper, we propose a light-weighted approach which utilizes a convex eyepiece to reduce visual discomfort induced by stereoscopic vision. An empirical experiment was conducted to examine the feasibility of convex eyepiece in a large depth of field (DOF) at close viewing distance both objectively and subjectively. The result shows the positive effects of convex eyepiece on the relief of eyestrain.

    Infrasound sensors are now being installed at Global Seismic Network (GSN) stations meeting certain infrastructure criteria. Manufactured by Hyperion Technology Group, Inc., these instruments (model IFS-3312) have a nominal sensitivity of 140 mV/Pa (at 1 Hz), a full-scale range of ±100 Pa, and a dynamic range of 120 dB. Low power consumption (750 mW at 12 VDC) and small size (153 mm x 178 mm) ease incorporation into the mix of existing GSN instrumentation. The accompanying flexible rosette ("Flexette") acoustic wind-noise reducing system, designed by Project IDA (International Deployment of Accelerometers-IDA), optimally includes 24 inlets, 4 secondary manifolds, and a single primary manifold. Each secondary manifold is connected to 6 inlets and to the primary manifold by 10-ft air hoses, thus eliminating stresses and the greater potential for leaks associated with the use of pipe. While the main design goal was to maximize the reduction of acoustic wind-noise over the widest range of wind speeds possible, consideration of additional criteria resulted in a Flexette base design easily tailored to meet individual station constraints and restrictions, made up of inexpensive (total cost Marshall Islands), in August 2017. During the next 6 months infrasound capability will be extended to IDA GSN stations BORG (Borganes, Iceland), EFI (Mount Kent, East Falkland Islands), and SACV (Santiago Island, Cape Verde).As with other data from GSN stations, real-time infrasound data are freely available from the Incorporated Research Institutions for Seismology-Data Management Center (IRIS-DMC).

    SeaView is an NSF-funded EarthCube Integrative Activity Project working with 5 existing data repositories* to provide oceanographers with highly integrated thematic data collections in user-requested formats. The project has three complementary goals: Supporting Scientists: SeaView targets scientists' need for easy access to data of interest that are ready to import into their preferred tool. Strengthening Repositories: By integrating data from multiple repositories for science use, SeaView is helping the ocean data repositories align their data and processes and make ocean data more accessible and easily integrated. Informing EarthCube (earthcube.org): SeaView's experience as an integration demonstration can inform the larger NSF EarthCube architecture and design effort. The challenges faced in this small-scale effort are informative to geosciences cyberinfrastructure more generally. Here we focus on the lessons learned that may inform other data facilities and integrative architecture projects. (The SeaView data collections will be presented at the Ocean Sciences 2018 meeting.) One example is the importance of shared semantics, with persistent identifiers, for key integration elements across the data sets (e.g. cruise, parameter, and project/program.) These must allow for revision through time and should have an agreed authority or process for resolving conflicts: aligning identifiers and correcting errors were time consuming and often required both deep domain knowledge and "back end" knowledge of the data facilities. Another example is the need for robust provenance, and tools that support automated or semi-automated data transform pipelines that capture provenance. Multiple copies and versions of data are now flowing into repositories, and onward to long-term archives such as NOAA NCEI and umbrella portals such as DataONE. Exact copies can be identified with hashes (for those that have the skills), but it can be painfully difficult to understand the processing

    This study is to calculate the proper angle for the optimal image of PNS Water's view on children, comparing and analyzing the PNS Water's projection angles between children and adults at every age. This study randomly selected 50 patients who visited the Medical Center from January to May in 2005, and examined the incidence path of central ray, taking a PNS Water's and skull trans-Lat. view in Water's filming position while attaching a lead ball mark on the Orbit, EAM, and acanthion of the patient's skull. And then, we calculated the incidence angles (angle A) of the line connected from OML and the petrous ridge to the inferior margin of maxilla on general (random) patient's skull image, following the incidence path of central ray. Finally, we analyzed two pieces of the graphs at ages, developing out the patient's ideal images at PNS Water's filming position taken by a digital camera, and calculating the angle (angle B) between OML and IP(Image Plate). The angle between OML and IP is about 43 .deg. in 4-years-old children, which is higher than 37 .deg. as age increases the angle decreases, it goes to 37 .deg. around 30 years of age. That is similar result to maxillary growth period. We can get better quality of Water's image for children when taking the PNS Water's view if we change the projection angles, considering maxillary growth for patients in every age stage

    School science students can benefit greatly from participation in student-directed, open-ended scientific inquiry projects. For various possible reasons, however, students tend not to be engaged in such inquiries. Among factors that may limit their opportunities to engage in open-ended inquiries of their design are teachers' conceptions about science. To explore possible relationships between teachers' conceptions about science and the types of inquiry activities in which they engage students, instrumental case studies of five secondary science teachers were developed, using field notes, repertory grids, samples of lesson plans and student activities, and semistructured interviews. Based on constructivist grounded theory analysis, participating teachers' tendencies to promote student-directed, open-ended scientific inquiry projects seemed to correspond with positions about the nature of science to which they indicated adherence. A tendency to encourage and enable students to carry out student-directed, open-ended scientific inquiry projects appeared to be associated with adherence to social constructivist views about science. Teachers who opposed social constructivist views tended to prefer tight control of student knowledge building procedures and conclusions. We suggest that these results can be explained with reference to human psychological factors, including those associated with teachers' self-esteem and their relationships with knowledge-building processes in the discipline of their teaching.

    Certain patients, through projective identification and splitting mechanisms, test the boundaries of the analytic situation. These patients are usually experiencing overwhelming paranoid-schizoid anxieties and view the object as ruthless and persecutory. Using a Kleinian perspective, the author advocates greater analytic flexibility with these difficult patients who seem unable to use the standard analytic environment. The concept of self-disclosure is examined, and the author discusses certain technical situations where self-disclosure may be helpful.(The Journal of Psychotherapy Practice and Research 1999; 8:225–233) PMID:10413442

    When we speak of an aerogel material, we are referring more to process and structure am to a specific substance. Aerogel, considered the lightest solid material, has been made from silica for seventy years. Resorcinol-formaldehyde, organic aerogels have been developed more recently. However, aerogel can be made from almost any type of substance, even lead. Because an aerogel is mostly air (about 99 %), the solid substance used will affect the weight very little. The term "aerogel" connotes the sol-gel process used to manufacture the material. The aerogel begins as a liquid "sol," becomes a solid "alcogel," and is then dried to become an "aerogel." The final product has a unique structure, useful for exploitation. It is an "open pore" system with nano-sized particles and pores, has very high surface area, and is highly interconnected. Besides low weight, aerogels have ultimate (lowest) values in other properties: thermal conductivity, refractive index, sound speed, and dielectric constant. Aerogels were first prepared in 1931 by Steven Kistler, who used a supercritical drying step to replace the liquid in a gel with air, preserving the structure (1). Kistler's procedure involved a water-to-alcohol exchange step; in the 1970's, this step was eliminated when a French investigator introduced the use of tetramethylorthosilicate. Still, alcohol drying involved dangerously high temperatures and pressures. In the 1980's, the Microstructured Materials Group at Berkeley Laboratory found that the alcohol in the gel could be replaced with liquid carbon dioxide before supercritical drying, which greatly improved safety (2). 'Me most recent major contribution has been that of Deshpande, Smith and Brinker in New Mexico, who are working to eliminate the supercritical drying step (3). When aerogels were first being developed, they were evaporatively dried. However, the wet gel, when dried, underwent severe shrinkage and cracking; this product was termed "xerogel." When the autoclave drying step was introduced, the final product was without cracks and showed only minimal shrinkage; this product was termed "aerogel." In the 1990's, Deshpande, Smith and Brinker developed an evaporative drying procedure in which the wet gel is chemically "capped" so that the material, which undergoes shrinkage, springs back to its original size when evaporatively dried. This new type of xerogel, while uncracked and almost the same size as the wet gel, differs from the autoclave-dried product in that it is less porous (approximately 70%, as compared to 99% for aerogels).

    Full Text Available This paper provides an outline of how the economic evaluation and selection of road construction projects can be complemented by social evaluation with a view to achieving a more equitable welfare distribution within a developing country. The article commences by elaborating on the general economic benefits that can arise from investment in economically justified road infrastructure. The different classes of non-road-user beneficiaries are idenified and discussed. The operational characteristics of road transport that are conducive to the stimulation of economic activity are identified and described. The present inequality of income distribution in South Africa is dealt with briefly, followed by a discussion and analysis on the use of equity weights in project evaluation to help bring about a more equitable welfare distribution.

    Participation in horticulture and arts may improve wellbeing in those with mental and physical illness. To conduct an in-depth exploration of the views and experience of participants of a primary-care-based horticultural and participatory arts rehabilitation project (Sydenham Garden). Qualitative interview study of a primary-care-based horticultural and participatory arts rehabilitation project in South London. Semi-structured interviews were conducted with 16 participants (referred to as 'coworkers') of Sydenham Garden. Seven were female. Participants were aged between 38 and 91 years and had a range of severe mental and physical health problems; most had depression. The interviews were analysed using constant comparison and thematic analysis. Data were overwhelmingly positive concerning participation. Coworkers considered participation in the project to promote wellbeing by providing purposeful and enjoyable activity and interest, improving mood and self-perceptions, and providing an escape from life's pressures. Being outdoors was considered therapeutic. The most-valued aspect of participation was the social contact derived as a result of it. Many of the coworkers who were interviewed developed transferable skills, including nationally recognised qualifications, which they valued highly. Delivery of horticultural therapy and participatory arts is a feasible model for improving wellbeing in patients in primary care who have serious illness. Longer-term studies are needed to address what happens to people after leaving such projects.

    Chinese stakeholders (131) from 68 key institutions in 27 provinces were consulted in spring 2009 in an online survey of their perceptions of the barriers and opportunities in financing large-scale carbon dioxide capture and storage (CCS) demonstration projects in China. The online survey was supplemented by 31 follow-up face-to-face interviews. The National Development and Reform Commission (NDRC) was widely perceived as the most important institution in authorizing the first commercial-scale CCS demonstration project and authorization was viewed as more similar to that for a power project than a chemicals project. There were disagreements, however, on the appropriate size for a demonstration plant, the type of capture, and the type of storage. Most stakeholders believed that the international image of the Chinese Government could benefit from demonstrating commercial CCS and that such a project could also create advantages for Chinese companies investing in CCS technologies. In more detailed interviews with 16 financial officials, we found striking disagreements over the perceived risks of demonstrating CCS. The rate of return seen as appropriate for financing demonstration projects was split between stakeholders from development banks (who supported a rate of 5-8%) and those from commercial banks (12-20%). The divergence on rate alone could result in as much as a 40% difference in the cost of CO(2) abatement and 56% higher levelized cost of electricity based on a hypothetical case study of a typical 600-MW new build ultrasupercritical pulverized coal-fired (USCPC) power plant. To finance the extra operational costs, there were sharp divisions over which institutions should bear the brunt of financing although, overall, more than half of the support was expected to come from foreign and Chinese governments.

    Basic communication research has identified a major social problem: communicating about cancer from diagnosis through death of a loved one. Over the past decade, an award-winning investigation into how family members talk through cancer on the telephone, based on a corpus of 61 phone calls over a period of 13 months, has been transformed into a theatrical production entitled The Cancer Play. All dialogue in the play is drawn from naturally occurring (transcribed) interactions between family members as they navigate their way through the trials, tribulations, hopes, and triumphs of a cancer journey. This dramatic performance explicitly acknowledges the power of the arts as an exceptional learning tool for extending empirical research, exploring ordinary family life, and exposing the often taken-for-granted conceptions of health and illness. In this study, a Phase I STTR project funded by the National Cancer Institute (NCI), we assess the feasibility of educating and impacting cancer patients, family members, and medical professionals who viewed the play as a live performance and through DVD screenings. Pre- and postperformance questionnaires were administered to solicit audience feedback. Pre-post change scores demonstrate overwhelming and positive impacts for changing opinions about the perceived importance, and attributed significance, of family communication in the midst of cancer. Paired-sample t-tests were conducted on five factor-analyzed indices/indicators-two indices of opinions about cancer and family communication, two indices measuring the importance of key communication activities, and the self-efficacy indicator-and all factors improved significantly (<.001). Informal talkback sessions were also held following the viewings, and selected audience members participated in focus groups. Talkback and focus-group sessions generated equally strong, support responses. Implications of the Phase I study are being applied in Phase II, a currently funded effort to

  16. Age Stereotypes and Self-Views Revisited: Patterns of Internalization and Projection Processes Across the Life Span.

    Kornadt, Anna E; Voss, Peggy; Rothermund, Klaus

    2017-07-01

    We investigated processes of age stereotype internalization into the self and projection of self-views onto age stereotypes from a life-span perspective, taking age-related differences in the relevance of life domains into account. Age stereotypes and self-views in eight life domains were assessed in a sample of N = 593 persons aged 30-80 years (T1) at two time points that were separated by a 4-year time interval. We estimated cross-lagged projection and internalization effects in multigroup structural equation models. Internalization and projection effects were contingent on age group and life domain: Internalization effects were strongest in the young and middle-aged groups and emerged in the domains family, personality, work, and leisure. Projection effects in different domains were most pronounced for older participants. Our findings suggest that the internalization of age stereotypes is triggered by domain-specific expectations of impending age-related changes and transitions during certain phases of the life span. Projection processes, however, seem to occur in response to changes that have already been experienced by the individual. Our study demonstrates the dynamic interrelation of age stereotypes and self-views across the life course and highlights the importance of a differentiated, life-span perspective for the understanding of these mechanisms. © The Author 2015.

  17. MO-FG-204-08: Optimization-Based Image Reconstruction From Unevenly Distributed Sparse Projection Views

    International Nuclear Information System (INIS)

    Xie, Huiqiao; Yang, Yi; Tang, Xiangyang; Niu, Tianye; Ren, Yi

    2015-01-01

    Purpose: Optimization-based reconstruction has been proposed and investigated for reconstructing CT images from sparse views, as such the radiation dose can be substantially reduced while maintaining acceptable image quality. The investigation has so far focused on reconstruction from evenly distributed sparse views. Recognizing the clinical situations wherein only unevenly sparse views are available, e.g., image guided radiation therapy, CT perfusion and multi-cycle cardiovascular imaging, we investigate the performance of optimization-based image reconstruction from unevenly sparse projection views in this work. Methods: The investigation is carried out using the FORBILD and an anthropomorphic head phantoms. In the study, 82 views, which are evenly sorted out from a full (360°) axial CT scan consisting of 984 views, form sub-scan I. Another 82 views are sorted out in a similar manner to form sub-scan II. As such, a CT scan with sparse (164) views at 1:6 ratio are formed. By shifting the two sub-scans relatively in view angulation, a CT scan with unevenly distributed sparse (164) views at 1:6 ratio are formed. An optimization-based method is implemented to reconstruct images from the unevenly distributed views. By taking the FBP reconstruction from the full scan (984 views) as the reference, the root mean square (RMS) between the reference and the optimization-based reconstruction is used to evaluate the performance quantitatively. Results: In visual inspection, the optimization-based method outperforms the FBP substantially in the reconstruction from unevenly distributed, which are quantitatively verified by the RMS gauged globally and in ROIs in both the FORBILD and anthropomorphic head phantoms. The RMS increases with increasing severity in the uneven angular distribution, especially in the case of anthropomorphic head phantom. Conclusion: The optimization-based image reconstruction can save radiation dose up to 12-fold while providing acceptable image quality

    Projects which directly could have dealt with moisture evaluation. As a result, independent and complementary targets have been singled out. To cite a few, interesting exchange of views took place in both the First and Second Action General Meetings of Rome and Vienna, respectively, in July 2013 and May 2014. In addition, a questionnaire with a relevant list of topics together with the identification of test scenarios for advanced comparison of inspection procedures have gathered invaluable information on the main expertises, fields of application, and equipments managed by the Project participants. The heterogeneous scenario outlined consequently, has indeed represented the third main issue to address. According to the Participants responses, roads were found to be the main target investigated (53%) so far, followed by soil materials (21%). In line with this, asphalt and compacted loose materials gathered the main interest among the main constituent materials with, respectively, 39% and 22%, as well as organic soils (22%). In this framework, the intermediate scale of investigation s, i.e., 0.01 m2 issue has been focused at avoiding the research to get blocked by ensuring a continuous updating of the latest results in moisture assessment using ground-penetrating radar achieved by Project 2.5 Participants [3-9].

    2005-01-01

    The analysis of our epistemic situation regarding singular events, such as abrupt climate change, shows essential limitations in the traditional modes of dealing with uncertainty. Typical cognitive barriers lead to the paralysis of action. What is needed is taking seriously the reality of the future. We argue for the application of the methodology of ongoing normative assessment. We show that it is, paradoxically, a matter of forming a project on the basis of a fixed future which one does not want, and this in a coordinated way at the level of social institutions. Ongoing assessment may be viewed as a prescription to live with uncertainty, in a particular sense of the term, in order for a future catastrophe not to occur. The assessment is necessarily normative in that it must include the anticipation of a retrospective ethical judgment on present choices (notion of moral luck). (authors)

    Purpose: To analyze the effects of projection-view (PV) distribution on the contrast and spatial blurring of microcalcifications on the tomosynthesized slices (X-Y plane) and along the depth (Z) direction for the same radiation dose in digital breast tomosynthesis (DBT). Methods: A GE GEN2 prototype DBT system was used for acquisition of DBT scans. The system acquires PV images from 21 angles in 3 deg. increments over a ±30 deg. range. From these acquired PV images, the authors selected six subsets of PV images to simulate DBT of different angular ranges and angular increments. The number of PV images in each subset was fixed at 11 to simulate a constant total dose. These different PV distributions were subjectively divided into three categories: uniform group, nonuniform central group, and nonuniform extreme group with different angular ranges and angular increments. The simultaneous algebraic reconstruction technique (SART) was applied to each subset to reconstruct the DBT slices. A selective diffusion regularization method was employed to suppress noise. The image quality of microcalcifications in the reconstructed DBTs with different PV distributions was compared using the DBT scans of an American College of Radiology phantom and three human subjects. The contrast-to-noise ratio (CNR) and the full width at half maximum (FWHM) of the line profiles of microcalcifications within their in-focus DBT slices (parallel to detector plane) and the FWHMs of the interplane artifact spread function (ASF) in the Z-direction (perpendicular to detector plane) were used as image quality measures. Results: The results indicate that DBT acquired with a large angular range or, for an equal angular range,with a large fraction of PVs at large angles yielded superior ASF with smaller FWHM in the Z-direction. PV distributions with a narrow angular range or a large fraction of PVs at small angles had stronger interplane artifacts. In the X-Y focal planes, the effect of PV

    Full Text Available In this paper, a successful and fruitful joint project will be presented. The project joins participants from 9 countries and from 15 universities. Since it started in 2001, this project entitled “Software Engineering: Computer Science Education and Research Cooperation” helped participants to gain excellent, up to date educational material, apply modern teaching methods, exchange experiences with other participants, and work jointly on the further development of lectures, case-studies, assignments, examination questions, and other necessary elements of a course. Project works under auspices of Stability Pact of South-Eastern Europe, and is supported by DAAD. The project started with the creation of a common beginning course in “Software Engineering”, but over time it grew and the number of other courses was developed. Finished almost completely are the courses in “Object-oriented programming”, “Software Project Management”, “Advanced Compiler Construction”, and “Data Structures and Algorithms”, and some other courses are under development. Aside from the educational collaboration, project members also developed good scientific cooperation, and published several research papers.

    This paper gives an overview of the factors leading to the decision to construct the Heysham 2 and Heysham 2 and Torness AGR using Agency Agreements and the experiences and lessons learnt during their operation. Inevitably some of the factors and problems described in this paper are not unique to Agency Agreements and are generic to project management of large engineering construction projects. The success and failures are therefore not necessarily attributable directly to the Agency arrangements. There are also a number of external factors (such as the national industrial relations climate) which contributed to the project but are not directly dealt with in the paper. (author)

In a large-scale survey, the relevant views that each group attributed to a contemporary Jesus differed almost as much as their own views. Despite such dissonance-reducing projection, however, conservatives acknowledged the relevant discrepancy with regard to “fellowship” issues (e.g., taxation to reduce economic inequality and treatment of immigrants) and liberals acknowledged the relevant discrepancy with regard to “morality” issues (e.g., abortion and gay marriage). However, conservatives also claimed that a contemporary Jesus would be even more conservative than themselves on the former issues whereas liberals claimed that Jesus would be even more liberal than themselves on the latter issues. Further reducing potential dissonance, liberal and conservative Christians differed markedly in the types of issues they claimed to be more central to their faith. A concluding discussion considers the relationship between individual motivational processes and more social processes that may underlie the present findings, as well as implications for contemporary social and political conflict.

    Global warming is expected to drive increasing extreme sea levels (ESLs) and flood risk along the world's coasts. The present contribution aims to present global ESL projections obtained by combining dynamic simulations of all the major ESL components during the present century, considering the latest CMIP5 projections for RCP4.5 and RCP8.5. Baseline values are obtained combining global re-analyses of tides, waves, and storm surges, including the effects of tropical cyclones. The global average RSLR is projected around 20 and 24 cm by the 2050s under RCP4.5 and RCP8.5, respectively and is projected to reach 46 and 67 cm by the year 2100. The largest increases in MSL are projected along the South Pacific, Australia and West Africa, while the smaller RSLR is projected around East North America, and Europe. Contributions from waves and storm surges show a very weak increasing global trend, which becomes statistically significant only towards the end of the century and under RCP8.5. However, for areas like the East China Sea, Sea of Japan, Alaska, East Bering Sea, as well as the Southern Ocean, climate extremes could increase up to 15%. By the end of this century the 100-year event ESL along the world's coastlines will on average increase by 48 cm for RCP4.5 and 75 cm for RCP8.5. The strongest rise is projected along the Southern Ocean exceeding 1 m under RCP8.5 by the end of the century. Increase exceeding 80 cm is projected for East Asia, West North America, East South America, and the North Indian Ocean. Considering always the business as usual and the year 2100, the lowest increase in ESL100 is projected along the East North America and Europe (below 50 cm). The present findings indicate that, under both RCPs, by the year 2050 the present day 100-year event will occur every 5 years along a large part of the tropics, rendering coastal zones exposed to intermittent flood hazard.

    Computer tomographs have progressed rapidly, and in the latest high performance types, the photographing time has been shortened to less than 5 sec, but the clear images of hearts have not yet been obtained. The X-ray tomographs used so far irradiate X-ray from many directions and measure the projected data, but by limiting projection direction to a small number, it was planned to shorter the X-ray photographing time and to reduce X-ray exposure as the objective of this study. In this paper, a method is proposed, by which tomographic images are reconstructed from projected data in a small number of direction by generalized inverse matrix penalty method. This method is the calculation method newly devised by the authors for this purpose. It is a kind of the nonlinear planning method added with the restrictive condition using a generalized inverse matrix, and it is characterized by the simple calculation procedure and rapid convergence. Moreover, the effect on reconstructed images when errors are included in projected data was examined. Also, the simple computer simulation to reconstruct tomographic images using the projected data in four directions was performed, and the usefulness of this method was confirmed. It contributes to the development of superhigh speed tomographs in future. (Kako, I.)

    Large screen information displays are defined as dynamic electronic displays that can be viewed by more than one person and are at least 2-feet wide. These large area displays for public viewing provide convenience, entertainment, security, and efficiency to the viewers. There are numerous uses for large screen information displays including those in advertising, transportation, traffic control, conference room presentations, computer aided design, banking, and military command/control. A noticeable characteristic of the large screen display market is the interchangeability of display types. For any given application, the user can usually choose from at least three alternative technologies, and sometimes from many more. Some display types have features that make them suitable for specific applications due to temperature, brightness, power consumption, or other such characteristic. The overall worldwide unit consumption of large screen information displays of all types and for all applications (excluding consumer TV) will increase from 401,109 units in 1995 to 655,797 units in 2002. On a unit consumption basis, applications in business and education represent the largest share of unit consumption over this time period; in 1995, this application represented 69.7% of the total. The market (value of shipments) will grow from DOL3.1 billion in 1995 to DOL3.9 billion in 2002. The market will be dominated by front LCD projectors and LCD overhead projector plates.

    Climate projections produced with CMIP5 and applied by the Intergovernmental Panel on Climate Change (IPCC) in its fifth assessment report indicate that changes in precipitation and temperature are expected to occur throughout Europe in the 21th century, with a likely decrease of water availability in many regions. Besides, water demand is also expected to increase, in link with these expected climate modifications, but also due to socio-economic and demographic changes. In this respect, the use of future freshwater resources may not be sustainable from the current water management perspective. Therefore adaptation strategies will most likely be needed to cope with these evolutions. In this context, the main objective of the ClimAware project (2010-2013 - www.uni-kassel.de/fb14/wasserbau/CLIMAWARE/, a project implemented within the IWRM-NET Funding Initiative) was to analyse the impacts of climate change (CC) on freshwater resources at the continental and regional scales and to identify efficient adaptation strategies to improve water management for various socio-economic sectors. This should contribute to a more effective implementation of the Water Framework Directive (WFD) and its instruments (river basin management plans, programmes of measures). The project developed integrated measures for improved freshwater management under CC constraints. More specifically, the objectives of the ClimAware project were to: • elaborate quantitative projections of changes in river flows and consequences such as flood frequency, drought occurrence and sectorial water uses. • analyse the effect of CC on the hydromorphological reference conditions of rivers and therefore the definition of "good status". • define management rules/strategies concerning dam management and irrigation practices on different time perspectives. • investigate uncertainties in climate model - scenario combinations. The research approach considered both European and regional perspectives, to get

    The purpose of this study is to analyze the perception of the content of health technology assessment (HTA) among health professionals applying for a state grant of DKK 10 million. A total of 113 applications were received and analyzed. When conducting the analysis, it was assumed that the applicants' maximum five-page project description would reflect: a) the applicants' perception of what an HTA is; b) how the assessment was to be conducted; and c) what the results were going to be used for. More than 40% of all applications focused on treatment; in 51% only one or two professional groups were to be involved (thus interdisciplinarity was questionable); only 22% of the HTA cases were intended to form the basis for political/administrative decisions; in general, the HTAs were planned far less comprehensively than was relevant; 76% of the projects did not include a formal synthesis phase; 41% intended to use diffusion as the only method for publication of the HTA result. The analysis reveals several areas where DIHTA has to make an effort in order to secure that HTA in fact constitutes a comprehensive and well-documented basis for decision making. These areas concern the following topics: multidisciplinarity, the objective of HTA, comprehensiveness, the synthesis phase, and publication and utilization of the HTA result.

    The development of the Chaîne des Puys and Limagne Fault World Heritage UNESCO project has taken about five years, since the Laboratoire Magmas et Volcans was approached by the local Auvergne government. Before this we had been working locally with organisations such as the Lemptégy volcano and Vulcania to help disseminate geoscience ideas to the general public, however the UNESCO project has lead us to do much more outreach. It has also stimulated our research and has taught us to better explain this to the lay person. In visiting other heritage projects, where we have exchanged ideas and best practice, we have been able to help other sites and improve what we do. These links are particularly important, as they can be used to help broaden the outlook of the general public and local actors, and increase further earth science literacy. I have noticed a strong increase in the awareness of the volcanoes, and volcanism as a result of the Chaîne des Puys and Limagne Fault project. I think that, before, many locals considered the volcanoes only as their special back garden, for easy walks and views and leisure, or for that matter farming, mining and hunting. However, now, there is a greater sense of pride rooted in the increased awareness of their geological significance in a historical and global context. While this effect is clear for the volcanoes, it is not yet apparent for the fault. The lay person has no clear concept of a rift and a fault. Thus, one of our major present challenges is to open the public's eyes to the fault. This is vital for the UNESCO project not only for educational reasons, but also because the fault scarp is a natural barrier that protects the rest of the property from urban development. Only if there is awareness of its nature and significance will it be an effective defence. To arrive at this goal, there is now a local government sponsored project to create and disseminate fault walks, fault viewpoints and fault information points. This is

    1985-01-01

    Fundamental studies have been made on the application of mathematical programming to the reconstruction of tomographic images from projections of a small number of views without requiring any circular symmetry nor periodicity. Linear programming and quadratic programming were applied to minimize the quadratic sum of the residue and to finally obtain optimized reconstruction images. The mathematical algorithms were verified by the method of computer simulation, and the relationship between the number of picture elements and the number of iterations necessary for convergence was also investigated. The methods of linear programming and quadratic programming require fairly simple mathematical procedures, and strict solutions can be obtained within a finite number of iterations. Their only draw back is the requirement of a large quantity of computer memory. But this problem will be desolved by the advent of large fast memory devices in the near future. (Aoki, K.)

The type of this research was qualitative which was descriptive. To obtained the validity of the qualitative data, the checking technique used in this research was sources triangulation, which had been done by comparing the suitability of the obtained data from the results of the interview and the test. Population of this research was the students of grade VIII at SMP Negeri 1 Sidoharjo and the sample was the students from VIII A Class. At the final, 12 research subjects were chosen to represent the group of level 1 self-efficacy, level 2 self-efficacy, level 3 self-efficacy, level 4 self efficacy, level 5 self-efficacy, and level 6 self-efficacy. In this research, there was a finding which shows us that the students with high self-efficacy had low ability to finish the geometrical reasoning ability test, while the students with low self-efficacy had the ability to finish the geometrical reasoning ability test. The factors which affected the finding were the motivations and the interest of learning mathematics which was affecting the attitude of the students in the classroom.

    Purpose: To investigate the feasibility of a new two-dimensional (2D) multichannel response (MCR) analysis approach for the detection of clustered microcalcifications (MCs) in digital breast tomosynthesis (DBT). Methods: With IRB approval and informed consent, a data set of two-view DBTs from 42 breasts containing biopsy-proven MC clusters was collected in this study. The authors developed a 2D approach for MC detection using projection view (PV) images rather than the reconstructed three-dimensional (3D) DBT volume. Signal-to-noise ratio (SNR) enhancement processing was first applied to each PV to enhance the potential MCs. The locations of MC candidates were then identified with iterative thresholding. The individual MCs were decomposed with Hermite–Gaussian (HG) and Laguerre–Gaussian (LG) basis functions and the channelized Hotelling model was trained to produce the MCRs for each MC on the 2D images. The MCRs from the PVs were fused in 3D by a coincidence counting method that backprojects the MC candidates on the PVs and traces the coincidence of their ray paths in 3D. The 3D MCR was used to differentiate the true MCs from false positives (FPs). Finally a dynamic clustering method was used to identify the potential MC clusters in the DBT volume based on the fact that true MCs of clinical significance appear in clusters. Using two-fold cross validation, the performance of the 3D MCR for classification of true and false MCs was estimated by the area under the receiver operating characteristic (ROC) curve and the overall performance of the MCR approach for detection of clustered MCs was assessed by free response receiver operating characteristic (FROC) analysis. Results: When the HG basis function was used for MCR analysis, the detection of MC cluster achieved case-based test sensitivities of 80% and 90% at the average FP rates of 0.65 and 1.55 FPs per DBT volume, respectively. With LG basis function, the average FP rates were 0.62 and 1.57 per DBT volume at

    Advanced Thermal Reactor (ATR) Fugen is a 557 MWt, 165 MWe, heavy water moderated, light-water cooled, pressure-tube type reactor. In 2003, Fugen was shut down after ca 25 years operation, and started decommissioning activity from 2008. In the initial period of decommissioning, we have been dismantling from turbine systems because of their little contamination. In general, most difficult process of dismantling of nuclear power plant is the dismantlement of the reactor core because the radiation rate of the reactor core is very high, e.g., it is over 200 Sv/hr in the Fugen's case. Our plan of dismantlement of the core is from about 2022. The core area has some features that the structure is narrow and complicated by tube-cluster structure that contains 224 fuel channels with both the pressure and the calandria tubes coaxially in each channel. The radiation shielding area is laminated structure composed of up to 150 mm thickness of carbon steel. And the structure of the reactor, which is made of various materials such as stainless steel, carbon steel, zirconium alloy and aluminum. In particular, the core area is planning to be dismantled under water by remote controlled machines in order to shield the radiation around the core and prevent airborne dust generated by the cutting considering the usage of Zr alloy which is likely to be oxidized. In consideration of above, the cutting methods were selected for dismantling the reactor core in order to shorten the dismantling term and reduce the secondary waste. The candidate cutting method options were decreased based on the results of the researches on achievement of the cutting methods domestically and internationally. Finally, the laser cutting method was selected for dismantling the core area and shielding area, and diamond wire saw was also selected for dismantling the shielding area applicable to concrete with metal liner, based on the results of some cutting tests. The laser cutting method has many advantages, e.g., narrow calf width leading to the reduction of secondary waste and remote-handle ability by using fiber laser. But this method has not yet been applied to reactor facilities throughout the world. Therefore for the safe and reliable dismantlement, laser cutting system in air will be organized and demonstration examinations to some equipment except core area will be carried out. Moreover, laser cutting system underwater should be also organized, taking a safety assessment data such as behavior of cutting dust. In the final stage, after inspection of dismantling procedure using mock-up device, after the core area is planning to be dismantled. This indicates an example of lessons-learned for the process of how the decommissioning program is planned and R and D for suitable technologies are implemented and they are applied to the final dismantlement process.

    This study is part of a first study of collaborative socio-environmental projects that engage Jewish and Arab students in Israel in learning about their local environment and about each other through outdoor learning and environmental action. We used ideas of social learning and environmental citizenship to frame our research. We investigated students' knowledge regarding their local environment and their knowledge of each other's community. We also studied the participants' views regarding their project-partners'environmental knowledge, awareness and behaviour in comparison to their own. Initially, differences were found regarding various aspects of the students' socio-environmental knowledge and in students' views of their counterparts' environmentalism. At the end of the projects, students showed better understanding of local socio-environmental issues and demonstrated changes in their original views towards the environmental awareness and behaviour of their counterparts. These findings suggest that projects which involve students from segregated communities not only promote environmental awareness but contribute to a reduction in mutual prejudices. We suggest that the differences we found are not related to ethnicity, but rather to students' socioeconomic status and experience in environmental education programmes.

    In digital breast tomosynthesis (DBT), quasi-three-dimensional (3D) structural information is reconstructed from a small number of 2D projection view (PV) mammograms acquired over a limited angular range. The authors developed preliminary computer-aided diagnosis (CADx) methods for classification of malignant and benign masses and compared the effectiveness of analyzing lesion characteristics in the reconstructed DBT slices and in the PVs. A data set of MLO view DBT of 99 patients containing 107 masses (56 malignant and 51 benign) was collected at the Massachusetts General Hospital with IRB approval. The DBTs were obtained with a GE prototype system which acquired 11 PVs over a 50 degree arc. The authors reconstructed the DBTs at 1 mm slice interval using a simultaneous algebraic reconstruction technique. The region of interest (ROI) containing the mass was marked by a radiologist in the DBT volume and the corresponding ROIs on the PVs were derived based on the imaging geometry. The subsequent processes were fully automated. For classification of masses using the DBT-slice approach, the mass on each slice was segmented by an active contour model initialized with adaptive k-means clustering. A spiculation likelihood map was generated by analysis of the gradient directions around the mass margin and spiculation features were extracted from the map. The rubber band straightening transform (RBST) was applied to a band of pixels around the segmented mass boundary. The RBST image was enhanced by Sobel filtering in the horizontal and vertical directions, from which run-length statistics texture features were extracted. Morphological features including those from the normalized radial length were designed to describe the mass shape. A feature space composed of the spiculation features, texture features, and morphological features extracted from the central slice alone and seven feature spaces obtained by averaging the corresponding features from three to 19 slices centered

    The European Integrated Data Archive (EIDA; http://www.orfeus-eu.org/eida/eida.html) is the distributed Data Centre system within ORFEUS, providing transparent access and services to high quality, seismic data across (currently) 9 large data archives in Europe. EIDA is growing, in terms of the number of participating data centres, the size of the archives, the variability of the data in the archives, the number of users, and the volume of downloads. The on-going success of EIDA is thus providing challenges that are the driving force behind the design of the next generation (NG) of EIDA, which is expected to be implemented within EPOS IP. EIDA ORFEUS must cope with further expansion of the system and more complex user requirements by developing new techniques and extended services. The EIDA NG is being designed to work on standard FDSN web services and two additional new web services: Routing Service and QC (quality controlled) service. This presentation highlights the challenges EIDA needs to address during the EPOS IP and focuses on these 2 new services. The Routing Service can be considered as the core of EIDA NG. It was designed to assist users and clients to locate data within a federated, decentralized data centre (e.g. EIDA). A detailed, FDSN-compliant specification of the service has been developed. Our implementation of this service will run at every EIDA node, but is also capable of running on a user's computer, allowing anyone to define virtual or integrate existing data centres. This (meta)service needs to be queried in order to locate the data. Some smart clients (in a beta status) have been also provided to offer the user an integrated view of the whole EIDA, hiding the complexity of its internal structure. The service is open and able to be queried by anyone without the need of credentials or authentication. The QC Service is developed to cope with user requirements to query for relevant data only. The web service provides detailed information on the

    2008-01-01

    Full Text Available Aim of the study is to assess how students in 6th, 7th and 8th grades of primary education see the project works made in science education and their implementation processes. The study was fulfilled upon the descriptive survey model to collect data. Participants of the research were 100 students who had project implementation experiences in science education, and they were from 24 primary schools in 7 districts randomly chosen in the city of Istanbul in Turkey. Data of the study were collected by using a semi-constructed interview form offered to students during the 2005-2006 teaching year. In the research, following items were examined: The extent to which students are inspired from the previously made projects during their own project selection process, the level of scientific document survey and the effects of contemporary events, science and technology class topics and students’ interest areas. It was seen that internet is the mostly used source to obtain information. For students, one of the most problematic issues faced during the project implementation is the time limits set out by teacher. It was found that the most obvious benefit obtained by students from the project works is their increasing interest towards science and technology class. The most significant change seen by students regarding project preparation is their increasing grades in exams during and following the project works.

  13. The relation of ongoing brain activity, evoked neural responses, and cognition

    2010-06-01

    Full Text Available Ongoing brain activity has been observed since the earliest neurophysiological recordings and is found over a wide range of temporal and spatial scales. It is characterized by remarkably large spontaneous modulations. Here, we review evidence for the functional role of these ongoing activity fluctuations and argue that they constitute an essential property of the neural architecture underlying cognition. The role of spontaneous activity fluctuations is probably best understood when considering both their spatiotemporal structure and their functional impact on cognition. We first briefly argue against a ‘segregationist’ view on ongoing activity, both in time and space, countering this view with an emphasis on integration within a hierarchical spatiotemporal organization of intrinsic activity. We then highlight the flexibility and context-sensitivity of intrinsic functional connectivity that suggest its involvement in functionally relevant information processing. This role in information processing is pursued by reviewing how ongoing brain activity interacts with afferent and efferent information exchange of the brain with its environment. We focus on the relationship between the variability of ongoing and evoked brain activity, and review recent reports that tie ongoing brain activity fluctuations to variability in human perception and behavior. Finally, these observations are discussed within the framework of the free-energy principle which – applied to human brain function - provides a theoretical account for a non-random, coordinated interaction of ongoing and evoked activity in perception and behaviour.

  14. Contrasting the Views and Actions of Data Collectors and Data Consumers in a Volunteer Water Quality Monitoring Project: Implications for Project Design and Management

    2017-12-01

    Full Text Available Data collection or generation is the primary way that the majority of volunteers advance the scientific goals of citizen science projects, but other activities such as data consumption also may influence learning, civic, and conservation outcomes. Project designers and managers balance goals for multiple outcomes and thus need to consider the influence of all project-related activities on outcomes. In a study of the kayak-based Citizen’s Water Quality Testing (CWQT Program in New York City, we compared the characteristics, perceptions, and behaviors of those collecting and using CWQT data (data collectors and those solely using the data (data consumers. Data collectors (n = 40 and consumers (n = 24 were similar in gender and political orientation, but collectors were younger, devoted more time to the project, and experienced far more face-to-face interactions related to the project. Data collectors and consumers had similar motivations for participation, except that collectors were more likely motivated by recognition for their efforts. Lack of free time was the largest barrier to participation for both types of participants, and a significantly greater barrier for consumers. Data collectors and consumers trusted volunteer-collected data more than government-collected data. Collectors and consumers both recognized multiple scientific, environmental, and social benefits associated with the project, and both were equally likely to use volunteer-collected data for a variety of purposes, such as informing decisions about conservation and recreation. Importantly, both groups were equally likely to undertake a suite of conservation behaviors. We synthesize and expand current conceptual frameworks of citizen science participation and outcomes, highlighting the need for further study to understand mechanisms and linkages between the varied activities of citizen science projects and broader social and ecological impacts.

    ENGLISH ABSTRACT: Transnet Freight Rail in South Africa has faced projects delays in its multi-project environment. This study takes South Africa as representative of developing countries, and develops the Critical Success Factors (CSFs model for multiple projects success, with the goal of expanding the conventional model by adding the demographic characteristics of the business units involved in the multiple projects. The empirical results showing the greatest number of success factors are people-related, with the focus on team selection and team commitment. Two demographic characteristics are of importance when managing multiple projects: the size of the business unit, and the employees’ project experience.

    AFRIKAANSE OPSOMMING: Transnet, ‘n spoorvragentiteit in Suid-Afrika, ondervind gereeld projekvertragings in hul multi-projekomgewing. Suid-Afrika, as ‘n voorbeeld van ontwikkelende lande, word in die studie gebruik en hierdie studie ontwikkel ‘n reeks suksesfaktore vir ‘n multi-projek-omgewing deur ‘n bestaande konvensionele model aan te pas om ook die demografiese eienskappe van die verskillende besigheidseenhede betrokke in die organisasie te inkorpo-reer. Die resultaat van die studie wys dat die grootste aantal suksesfaktore mens-geörienteerd is, met die fokus op die samestelling en toewyding van die betrokke projekspanne. Twee demografiese eienskape is belangrik by die bestuur van multi-projekte, naamlik die grootte van die besigheidseenheid asook projekondervinding van die werknemers.

  17. Assessment of highway infrastructure projects in Latin America and Perú from the competences point of view

    Directory of Open Access Journals (Sweden)

    Zevallos Germán Gallardo

    2017-01-01

    Full Text Available It is stressed that Latin America and Peru should become more competitive. Under the actual development scenarios, attention to competences of programme managers and project managers related to public transportation infrastructure projects has risen substantially. An inefficient bureaucratic system is related with deficiencies of people skills and competences. On the other hand, an excellent system demands quality of the system and quality of people working in it. Thus, it is important to have excellence in administration and excellent administrators in the public sector. Three main lacking elements have been identified: i lack of good education; ii absence of fair salaries in the public sector; and iii lack of incentives. Many misconceptions and disputed consequences have been observed and analyzed. It is clear that there is lack of competence among infrastructure transport project managers and teams, which causes trouble with the main goal of Peru getting benefits from these investments and achieving sustainable development. Furthermore, the right way to achieve these benefits is through a new model of education for project managers and programme managers in Peru. This education should be based more on competences than on qualifications. Thus, the International Project Management Association (IPMA competence baseline, which is the standard that best fits to these needs, needs to be implemented to achieve the real contribution and benefits of these projects to society.

    This study tests the relation between eye-movements and thought processing. Subjects were given specific modality tasks (visual, gustatory, kinesthetic) and assessed on whether they responded with distinct eye-movements. Some subjects' eye-movements reflected ongoing thought processing. Instead of a universal pattern, as suggested by the neurolinguistic programming hypothesis, this study yielded subject-specific idiosyncratic eye-movements across all modalities. Included is a discussion of the neurolinguistic programming hypothesis regarding eye-movements and its implications for the eye-movement desensitization and reprocessing theory.

    To demonstrate the efficiency of vitrifying mature human oocytes for different clinical indications. Descriptive case series. Cryobiology laboratory, Centro Colombiano de Fertilidad y Esterilidad-CECOLFES LTDA. (Bogotá, Colombia). Oocyte vitrification was offered as an alternative management for patients undergoing infertility treatment because of ovarian hyperstimulation syndrome, premature ovarian failure, natural ovarian failure, male factor, poor response, or oocyte donation. Mature oocytes were obtained from 33 donor women and 40 patients undergoing infertility treatment. Oocytes were retrieved by ultrasound-guided transvaginal aspiration and vitrified with the Cryotops method, with 30% ethylene glycol, 30% dimethyl sulfoxide, and 0.5 mol/L sucrose. Viability was assessed 3 hours after thawing. The surviving oocytes were inseminated by intracytoplasmic sperm injection. Fertilization was evaluated after 24 hours. The zygotes were further cultured in vitro for up to 72 hours until time of embryo transfer. Recovery, viability, fertilization, and pregnancy rates. Oocyte vitrification with the Cryotop method resulted in high rates of recovery, viability, fertilization, cleavage, and ongoing pregnancy. Vitrification with the Cryotop method is an efficient, fast, and economical method for oocyte cryopreservation that offers high rates of survival, fertilization, embryo development, and ongoing normal pregnancies, providing a new alternative for the management of female infertility.

  2. Using Project-Based Data in Physics to Examine Television Viewing in Relation to Student Performance in Science

    Science.gov (United States)

    Espinoza, Fernando

    2009-10-01

    Mass media, particularly television, influence public conceptions and attitudes toward learning science. The discovery of an original method that does not rely on self-reported viewing habits to measure the impact of television on students' performance in science arose from a study of a unit on electricity in a Physics course. In determining the number of television sets at home and the number of hours of operation, data emerged that allowed an investigation of associations between each of these variables and student performance in physics. A negative impact on performance was found in its consistent decrease as both the number of sets and the time the sets are on increase. These results provide dramatic independent confirmation of the negative impact of television viewing on achievement determined through meta-analysis of many studies, and are also consistent with those in the literature at large, particularly from the Third International Mathematics and Science Study, and the National Assessment of Educational Progress. Furthermore, the totally `blind' participation of the subjects lends a degree of authenticity rarely found in a classically designed study. The findings impact scientific literacy, since performance in science and conceptions of science and scientists, are all inextricably linked.

  3. The JSpecView Project: an Open Source Java viewer and converter for JCAMP-DX, and XML spectral data files

    Lancashire Robert J

    2007-12-01

    Full Text Available Abstract The JSpecView Open Source project began with the intention of providing both a teaching and research tool for the display of JCAMP-DX spectra. The development of the Java source code commenced under license in 2001 and was released as Open Source in March 2006. The scope was then broadened to take advantage of the XML initiative in Chemistry and routines to read and write AnIML and CMLspect documents were added. JSpecView has the ability to display the full range of JCAMP-DX formats and protocols and to display multiple spectra simultaneously. As an aid for the interpretation of spectra it was found useful to offer routines such that if any part of the spectral display is clicked, that region can be highlighted and the (x, y coordinates returned. This is conveniently handled using calls from JavaScript and the feedback results can be used to initiate links to other applets like Jmol, to generate a peak table, or even to load audio clips providing helpful hints. Whilst the current user base is still small, there are a number of sites that already feature the applet. A tutorial video showing how to examine NMR spectra using JSpecView has appeared on YouTube and was formatted for replay on iPods and it has been incorporated into a chemistry search engine.

    Despite many educational campaigns we still see burns caused by methylated spirit every year. We undertook a retrospective study to analyse the impact of this problem. We retrospectively collected data of all patients with burns caused by methylated spirit over twelve years from 1996 to 2008. Our main endpoints were: incidence, age, mechanism of injury, total body surface area (TBSA) burned, burn depth, need for surgery and length of hospital stay. Ninety-seven patients with methylated spirit burns were included. During the study period there was no decrease in the number of patients annually admitted to the burn unit with methylated spirit burns. 28% of the patients (n=27) were younger than eighteen years old, 15% (n=15) were ten years old or younger. The most common cause of burns was carelessness in activities involving barbecues, campfires and fondues. Mean TBSA burned was 16% (SD 12.4). 70% (n=68) had full thickness burns. 66% (n=64) needed grafting. Mean length of hospital stay was 23 days (SD 24.7). The use of methylated spirit is an ongoing problem, which continues to cause severe burns in adults and children. Therefore methylated spirit should be banned in households. We suggest sale only in specialised shops, clear labelling and mandatory warnings. Copyright © 2012 Elsevier Ltd and ISBI. All rights reserved.

    The Federal Drug Free Work Place Program (DFWP) has now matured to the point of being able to return employees to sensitive testing designated positions (TDP) after completion of treatment of their addiction. The known tendency of addicted individuals to suffer multiple relapses prior to their final recovery has resulted in several positive urine tests (relapses) occurring among those Federal employees who have already completed treatment and who have been returned to TDP's. The very real potential for further relapses occurring after additional employees return to TDP's will be a critical factor in the ultimate success of the DFWP and in the public's impression of the program's effectiveness. In response to this concern, NASA has begun development of its Ongoing Recovery Basic Information Tool (ORBIT) instrument. The aim of the NASA ORBIT is to provide Employee Assistance Program (EAP) professionals with an advanced clinical tool which will be helpful in supporting recovery from substance abuse and which will allow more accurate determinations of when clients may be successfully returned to sensitive positions.

  8. A Case Study of Framing and Project Design Impacts on Participant Identity, Views, and Trust of Science in a Phenology Public Participatory Program

    Sorensen, A. E.; Jordan, R.

    2016-12-01

    Recent literature has suggested public participatory research models (e.g., citizen science and similar) as a key opportunity for scientists to meaningfully engage and communicate with the public to increase support for science and encourage pro-science behavior. In this, there has been an inherent assumption that all models of engagement yield similar participant results with few examples of assessment of these programs. While many of these programs do share superficial similarities in their modes of participant engagement and participant motivation, there is a large disparity in participant engagement between them. This disparity suggests that framing of these projects (e.g., citizen science versus crowd sourcing) also plays an important role in decisions about participation. Additionally, participant outcomes, in terms of beliefs about scientific practices and scientific trust, between these two project types has not yet been investigated. To investigate the impact of framing, participants were recruited to a web-based tree phenology public participatory research program where half the participants were engaged in a citizen science framed program and the other were engaged in a crowdsourced framed project. The participants in each frame were engaged in the same task (reporting leaf budding/leaf drop), but the way the projects were framed differed. Post-participation we see that there are indeed statistically significant differences in participant outcomes between individuals who participated as a citizen scientist versus as a crowdsourcer. Particularly we see differences in terms of their views of science, identity, and trust of science. This work is the first to the authors' knowledge that aims to evaluate if projects can be treated synonymously when discussing potential for public engagement and broader trust and literacy outcomes.

    In 1981 the linear accelerator 'Neptun 10 p' will be mounted at the Radiological Clinic of the University of Greifswald. Its place will be an irradiation room which is equipped for a radiation of 1.33 MeV. The strengthening of walls and celling, which is necessary for 9 MeV bremsstrahlung and 10 MeV electron radiation, can only be realized by a self-supporting lead-steel construction for reasons of the distance to the neighbouring house and of the connected conditions of foundation as well as of the load capacity of the existing construction of the roof. As in the eighties similar problems are to be expected in other radiological hospitals of the GDR the constructive solution of the Greifswald linear accelerator project and connected problems of the radiation protection are represented.

    Full Text Available A total of 196 secondary schools participated in the Secondary 2 Program of the Full Implementation Phase of the Project P.A.T.H.S. (Positive Adolescent Training through Holistic Social Programmes. After completion of the Tier 1 Program, 30,731 students responded to the Subjective Outcome Evaluation Form (Form A to assess their perceptions of the program, instructors, and perceived effectiveness of the program. Based on the consolidated reports submitted by the schools to the funding body, the research team aggregated the consolidated data to form a “reconstructed” overall profile on the perceptions of the program participants. Findings demonstrated that high proportions of the respondents had positive perceptions of the program and the instructors, and roughly four-fifths of the respondents regarded the program as beneficial to them. Correlation analyses showed that perceived program and instructor characteristics were positively associated with perceived benefits of the program.

  12. Requirements for effective technology transfer for engineering and project management. The views of the recipient country and the technology supplier

    International Nuclear Information System (INIS)

    Backhaus, K.W.

    1986-04-01

    Technology transfer in the area of engineering and project management for nuclear power plant projects is considered a rather complex and sophisticated matter. Therefore only within a long-term nuclear co-operation a meaningful transfer of such a multifaceted technology can reasonably be achieved. A long-term nuclear co-operation anticipates a nuclear power plant program consisting of a few nuclear power plants of a certain type and size in order to achieve the indispensable effect ''learning by doing''. The objectives of nuclear technology transfer may be in general or in particular; absorption of a foreign nuclear technology and its adaptation to the conditions and needs of the receiver's country; built-up of industrial infrastructure for planning, construction and operation of nuclear power plants; raising of the general industrial level and achieve a spin-off effect; creation of a basis for independent development of nuclear technology. The technology transfer on one side and the construction program of nuclear power plants on the other side cannot be practiced by two parallel but separated event, however, they form one unit. Contrary to the import of industrial equipment in terms of ''black box'', by means of a nuclear technology transfer the introduction of new dependencies will be prevented. The technology transfer can remarkably be facilitated by forming a joint venture engineering company in the recipient country. The required know-how potential within a certain time period determines the intensity of the technology transfer and consequently the man power to be involved. The realization of such technology transfer is demonstrated by means of practical examples. (author). 12 figs

  13. Mauna Kea volcano's ongoing 18-year swarm

    Science.gov (United States)

    Wech, A.; Thelen, W. A.

    2017-12-01

    Mauna Kea is a large postshield-stage volcano that forms the highest peak on Hawaii Island. The 4,205-meter high volcano erupted most recently between 6,000 and 4,500 years ago and exhibits relatively low rates of seismicity, which are mostly tectonic in origin resulting from lithospheric flexure under the weight of the volcano. Here we identify deep repeating earthquakes occurring beneath the summit of Mauna Kea. These earthquakes, which are not part of the Hawaiian Volcano Observatory's regional network catalog, were initially detected through a systematic search for coherent seismicity using envelope cross-correlation, and subsequent analysis revealed the presence of a long-term, ongoing swarm. The events have energy concentrated at 2-7 Hz, and can be seen in filtered waveforms dating back to the earliest continuous data from a single station archived at IRIS from November 1999. We use a single-station (3 component) match-filter analysis to create a catalog of the repeating earthquakes for the past 18 years. Using two templates created through phase-weighted stacking of thousands of sta/lta-triggers, we find hundreds of thousands of M1.3-1.6 earthquakes repeating every 7-12 minutes throughout this entire time period, with many smaller events occurring in between. The earthquakes occur at 28-31 km depth directly beneath the summit within a conspicuous gap in seismicity surrounding the flanks of the volcano. Magnitudes and periodicity are remarkably stable long-term, but do exhibit slight variability and occasionally display higher variability on shorter time scales. Network geometry precludes obtaining a reliable focal mechanism, but we interpret the frequency content and hypocenters to infer a volcanic source distinct from the regional tectonic seismicity responding to the load of the island. In this model, the earthquakes may result from the slow, persistent degassing of a relic magma chamber at depth.

    2013-06-21

    On April 1, 2013, the Public Health Directorate of Angola announced that six cases of dengue had been reported to the Ministry of Health of Angola (MHA). As of May 31, a total of 517 suspected dengue cases had been reported and tested for dengue with a rapid diagnostic test (RDT). A total of 313 (60.5%) specimens tested positive for dengue, including one from a patient who died. All suspected cases were reported from Luanda Province, except for two from Malanje Province. Confirmatory diagnostic testing of 49 specimens (43 RDT-positive and six RDT-negative) at the CDC Dengue Branch confirmed dengue virus (DENV) infection in 100% of the RDT-positive specimens and 50% of the RDT-negative specimens. Only DENV-1 was detected by molecular diagnostic testing. Phylogenetic analysis indicated this virus has been circulating in the region since at least 1968, strongly suggesting that dengue is endemic in Angola. Health-care professionals throughout Angola should be aware of the ongoing epidemic, the recommended practices for clinical management of dengue patients, and the need to report cases to MHA. Persons in Angola should seek medical care for acute febrile illness to reduce the risk for developing complications. Laboratory-confirmed dengue also has been reported from seven countries on four continents among persons who had recently traveled to Luanda, including 79 persons from Portugal. Angola is the third of four African countries to report a dengue outbreak in 2013. Persons returning from Africa with acute febrile illness should seek medical care, including testing for DENV infection, and suspected cases should be reported to public health authorities.

  15. Project AProWa: a national view on managing trade-offs between agricultural production and conservation of aquatic ecosystems

    Swiss agriculture is legally committed to fulfill several, partially conflicting goals such as agricultural production on the one hand and the conservation of natural resources on the other hand. In the context of the research project AProWa ("Agricultural Production and Water"), the relationships between the production aspect and the conservation of aquatic ecosystems is analyzed with a holistic approach. Agricultural production and the protection of water resources have high potential for conflicts: Farmers use ground and surface water to irrigate their fields. On the other hand, drainage systems enable the production on otherwise unfavorably wet soils. These in turn often affect ground water recharge and divert precipitation directly into surface waters, which changes their hydrological regime. Typically, drainage systems also elevate the input of nutrients and pesticides into the water bodies. In general, applied fertilizers, plant protection products, veterinary drugs and phytohormones of cultivated plants are introduced into the ground and surface waters through different processes such as drift, leaching, runoff, preferential flow or erosion. They influence the nutrient cycles and ecological health of aquatic systems. The nutrient and pesticide loss processes themselves can be altered by tillage operations and other agricultural practices. Furthermore, the competition for space can lead to additional conflicts between agriculture and the protection of aquatic ecosystems. For example, channelized or otherwise morphologically changed rivers do not have a natural discharge pattern and are often not suitable for the local flora and fauna; but naturally meandering rivers need space that cannot be used for agriculture. In a highly industrialized and densely populated country like Switzerland, all these potential conflicts are of importance. Although it is typically seen as a water-rich country, local and seasonal overexploitation of rivers through water extraction

    When a molecule is adsorbed on a metal surface by chemical bonding new electronic states are formed. For noble and transition metals these adsorption-induced states overlap with the much more intense metal d-valence band, making them difficult to probe by for instance direct photoemission. However, it has recently been shown that X-ray emission spectroscopy (XES) can be applied to adsorbate systems. Since the intermediate state involves a core hole, this technique has the power to project out the partial density of states around each atomic site. Both the excitation and deexcitation processes are in general governed by the dipole selection rules. For oriented system, it is hence possible to obtain a complete separation into 2p{sub x}, 2p{sub y} and 2p{sub z} contributions using angular resolved measurements. The authors have applied XES together with other core level spectroscopies to glycine adsorption on Cu(110). Glycine (NH{sub 2}CH{sub 2}COOH) is the smallest amino acid and very suitable to study by core level spectroscopy since it has several functional groups, all well separated in energy by chemical shifts. Its properties are futhermore of biological interest. In summary, the authors have shown that it is possible to apply XES to more complicated molecular adsorbates. The assignment of different electronic states is however not as straight forward as for simple diatomic molecules. For a complete understanding of the redistribution and formation of new electronic states associated with the surface chemical bond, experimental data must be compared to theoretical calculations.

  17. Balancing Benefits and Risks of Immortal Data: Participants' Views of Open Consent in the Personal Genome Project.

    An individual's health, genetic, or environmental-exposure data, placed in an online repository, creates a valuable shared resource that can accelerate biomedical research and even open opportunities for crowd-sourcing discoveries by members of the public. But these data become "immortalized" in ways that may create lasting risk as well as benefit. Once shared on the Internet, the data are difficult or impossible to redact, and identities may be revealed by a process called data linkage, in which online data sets are matched to each other. Reidentification (re-ID), the process of associating an individual's name with data that were considered deidentified, poses risks such as insurance or employment discrimination, social stigma, and breach of the promises often made in informed-consent documents. At the same time, re-ID poses risks to researchers and indeed to the future of science, should re-ID end up undermining the trust and participation of potential research participants. The ethical challenges of online data sharing are heightened as so-called big data becomes an increasingly important research tool and driver of new research structures. Big data is shifting research to include large numbers of researchers and institutions as well as large numbers of participants providing diverse types of data, so the participants' consent relationship is no longer with a person or even a research institution. In addition, consent is further transformed because big data analysis often begins with descriptive inquiry and generation of a hypothesis, and the research questions cannot be clearly defined at the outset and may be unforeseeable over the long term. In this article, we consider how expanded data sharing poses new challenges, illustrated by genomics and the transition to new models of consent. We draw on the experiences of participants in an open data platform-the Personal Genome Project-to allow study participants to contribute their voices to inform ethical consent

    2015-09-01

    Full Text Available Geoengineering (also called climate engineering, which refers to large-scale intervention in the Earth's climate system to counteract greenhouse gas-induced warming, has been one of the most rapidly growing areas of climate research as a potential option for tackling global warming. Here, we provide an overview of the scientific background and research progress of proposed geoengineering schemes. Geoengineering can be broadly divided into two categories: solar geoengineering (also called solar radiation management, or SRM, which aims to reflect more sunlight to space, and carbon dioxide removal (CDR, which aims to reduce the CO2 content in the atmosphere. First, we review different proposed geoengineering methods involved in the solar radiation management and carbon dioxide removal schemes. Then, we discuss the fundamental science underlying the climate response to the carbon dioxide removal and solar radiation management schemes. We focus on two basic issues: 1 climate response to the reduction in solar irradiance and 2 climate response to the reduction in atmospheric CO2. Next, we introduce an ongoing geoengineering research project in China that is supported by National Key Basic Research Program. This research project, being the first coordinated geoengineering research program in China, will systematically investigate the physical mechanisms, climate impacts, and risk and governance of a few targeted geoengineering schemes. It is expected that this research program will help us gain a deep understanding of the physical science underlying geoengineering schemes and the impacts of geoengineering on global climate, in particular, on the Asia monsoon region.

  19. Can monaural temporal masking explain the ongoing precedence effect?

    2018-02-01

    The precedence effect for transient sounds has been proposed to be based primarily on monaural processes, manifested by asymmetric temporal masking. This study explored the potential for monaural explanations with longer ("ongoing") sounds exhibiting the precedence effect. Transient stimuli were single lead-lag noise burst pairs; ongoing stimuli were trains of 63 burst pairs. Unlike with transients, monaural masking data for ongoing sounds showed no advantage for the lead, and are inconsistent with asymmetric audibility as an explanation for ongoing precedence. This result, along with supplementary measurements of interaural time discrimination, suggests different explanations for transient and ongoing precedence.

    of the EDZ as well as hydro-chemical long-term stability in contact with different brines under diffusive and advective conditions, a comprehensive laboratory testing program is carried out. One of the most challenging aspects is the determination of the pre-experimental status of the core material that was provided for laboratory investigations, since the salt concrete was taken from an existing dam that has been loaded in-situ by the creeping rock salt for more than 10 years. Therefore, it is obvious that material properties, such as e.g. the initial gas permeability, have to be measured under a load comparable to the in-situ minimum stress. Within this paper preliminary results from laboratory investigations on salt concrete will be evaluated and an estimation of goals achievable within project lifetime will be given from a retrospective view on 24-month of investigation.

    The SRS is re-purposing its vast array of assets to solve future national issues regarding environmental stewardship, national security, and clean energy. The vehicle for this transformation is Enterprise SRS which presents a new, strategic view of SRS as a united endeavor for 'all things nuclear' as opposed to a group of distinct and separate entities with individual missions and organizations. Key among the Enterprise SRS strategic initiatives is the integration of research into facilities in conjunction with ongoing missions to provide researchers from other national laboratories, academic institutions, and commercial entities the opportunity to demonstrate their technologies in a relevant environment and scale prior to deployment. To manage that integration of research demonstrations into site facilities, The DOE Savannah River Operations Office, Savannah River Nuclear Solutions, and the Savannah River National Laboratory (SRNL) have established the Center for Applied Nuclear Materials Processing and Engineering Research (CANMPER). The key objective of this initiative is to bridge the gap between promising transformational nuclear materials management advancements and large-scale deployment of the technology by leveraging SRS assets (e.g. facilities, staff, and property) for those critical engineering-scale demonstrations necessary to assure the successful deployment of new technologies. CANMPER will coordinate the demonstration of R and D technologies and serve as the interface between the engineering-scale demonstration and the R and D programs, essentially providing cradle-to-grave support to the R and D team during the demonstration. While the initial focus of CANMPER will be on the effective use of SRS assets for these demonstrations, CANMPER also will work with research teams to identify opportunities to perform R and D demonstrations at other facilities. Unique to this approach is the fact that these SRS assets will continue to accomplish DOE's critical

  10. Ongoing and planned fuel safety research in NEA member states - Compiled from SEGFSM Members' Contributions

    International Nuclear Information System (INIS)

    2002-10-01

    This report is in response to an action placed on SEGFSM members to compile ongoing and planned fuel safety research in NEA member states with the aim of providing CSNI an overview on related R and D international programmes and projects, along with the identification of current and future needs and priorities. A questionnaire was distributed to SEGFSM members on 18 October 2000, requesting them to identify fuel safety research programmes and to provide information on achievements and future plans. The questionnaire required respondents to provide information on the ongoing R and D programmes under the following headings: Title; Research Laboratory/Sponsor(s); Objectives/Goals; Status of Work; Brief description/presentation of the main results achieved; Future plans; References. Replies were received from organizations in the following countries: Belgium, Canada, Czech Republic, France, Germany, Hungary, Japan, Korea, Norway (Halden Reactor Project), Sweden, Switzerland, United Kingdom, USA. The report is based on the information provided in the replies received, as a consequence it cannot be viewed as comprehensive; programmes may well be in progress in addition to those detailed here. It is also possible that the detailed results of some programmes may remain proprietary and therefore not available in the short term. The report is organized in topic sections relating to: fuel and clad studies, integral fuel rod tests and PIE, LOCA and RIA studies including whole rods and bundles as well as single effects studies of fuel and cladding, code development for both steady state and transient fuel behaviour, thermal hydraulics, reactor physics codes and finally severe accident studies. The main issues for the current generation of reactors are those of high burn-up performance in normal operations, LOCA and RIA conditions and the main goal for the industry is to consolidate the safety issues to bring all countries up to a licensed discharge burn-up of ∼60 MWd/kg in

    NONE

    1997-12-01

    This paper describes a joint US/Brazil pilot project for rural electrification, whose major goals are: to establish technical, institutional, and economic confidence in using renewable energy (PV and wind) to meet the needs of the citizens of rural Brazil; to establish on-going institutional, individual and business relationships necessary to implement sustainable programs and commitments; to lay the groundwork for larger scale rural electrification through the use of distributed renewable technologies. The projects have supported low power home lighting systems, lighting and refrigeration for schools and medical centers, and water pumping systems. This is viewed as a long term project, where much of the equipment will come from the US, but Brazil will be responsible for program management, and sharing data gained from the program. The paper describes in detail the Brazilian program which was instituted to support this phased project.

    2015-12-01

    Given the explosive growth in urbanization and its dominant role in current and future global greenhouse gas emissions, urban areas have received increasing research attention from the carbon cycle science community. The emerging focus is driven by the increasingly dense atmospheric observing capabilities - ground and space-based - in addition to the rising profile of cities within international climate change policymaking. Dominated by anthropogenic emissions, urban carbon cycle research requires a cross-disciplinary perspective with contributions from disciplines such as engineering, economics, social theory, and atmospheric science. We review the recent results from a sample of the active urban carbon research efforts including the INFLUX experiment (Indianapolis), the Megacity carbon project (Los Angeles), Salt Lake City, and Boston. Each of these efforts represent unique approaches in pursuit of different scientific and policy questions and assist in setting priorities for future research. From top-down atmospheric measurement systems to bottom-up estimation, these research efforts offer a view of the challenges and opportunities in urban carbon cycle research.

    1998-01-01

    Project financing was defined ('where a lender to a specific project has recourse only to the cash flow and assets of that project for repayment and security respectively') and its attributes were described. Project financing was said to be particularly well suited to power, pipeline, mining, telecommunications, petro-chemicals, road construction, and oil and gas projects, i.e. large infrastructure projects that are difficult to fund on-balance sheet, where the risk profile of a project does not fit the corporation's risk appetite, or where higher leverage is required. Sources of project financing were identified. The need to analyze and mitigate risks, and being aware that lenders always take a conservative view and gravitate towards the lowest common denominator, were considered the key to success in obtaining project financing funds. TransAlta Corporation's project financing experiences were used to illustrate the potential of this source of financing

    Full text: Present article is devoted to ongoing efforts to combat illicit trafficking in Tajikistan. The radiation protection system created in our country is the instrument for prevention of nuclear and radiological terrorism but such parts of the radiation protection infrastructure as accounting and control of sources of ionizing radiation, physical security of sources, means for detection and analysis of orphan sources and public information which is useful and helpful to prevent the nuclear and radioactive materials against theft, important equipment against sabotage, to prevent illegal trafficking of such materials is not developed due to the fact that socio-economic conditions were affected by civil war (1992-1997). The Republic of Tajikistan just in 2001 became the member of IAEA and the established regulatory authority is functioning just four years. There are currently 4 Laws and 6 regulations are worked out for ensuring the radiation safety in Tajikistan and new regulations are under the process of development. Mainly radiation safety in Tajikistan is based on the Law on Radiation Safety (June, 2003) and on the Law on Utilization of Atomic Energy (November, 2004). Unfortunately in the Republic of Tajikistan because of limited national budget there are no any appropriate and accredited technical services. There is only one functioning laboratory (Republican Chemical and Radiometric Laboratory) which performs measurements and radiation measurement laboratory analysis of material. Metrological attestation of devices and sources of this laboratory was carried out by the laboratory of technique measuring KSAVO (Central Asian military division) but it was in 1992. After that period no metrological attestation was carried out. Some devices were delivered under IAEA project but it is not enough at all to cover the needs of the country. One of the most disturbing problems nowadays is terrorism with use of nuclear materials. Also terrorists are able to use so

    International Nuclear Information System (INIS)

    Hoppe, W.

    1978-01-01

    For the licensing of power plants, nuclear power plants and other industrial large projects, the question of the building law admissibility gains more and more importance in the licensing procedure. According to paragraph 6 of the Fed. Immission Protection, it is not only necessary that immission protection duties of the operator of plants which are subject to licensing are fulfilled, but other public law regulations must be in correspondance with the construction and operation of the plant. In this connection, the planning law admissibility of the project must also be examined. This is also valid for nuclear power plants. In the practical application of licensing such plants are treated in different ways, as far as terms of building planning are concerned. Some licensing authorities regard them as priviledged outskirts projects, others demand a zoning plan of the community. The author pleads for such large projects to be licensed only on the basis of a zoning plan set up by the community. (orig.) [de

    We address cancer communication by creating and assessing the impacts of a theatrical production, When Cancer Calls…(WCC…), anchored in conversations from the first natural history of a patient and family members talking through cancer on the telephone. A national study was conducted using a multi-site and randomized controlled trial. An 80-minute video was produced to assess viewing impacts across cancer patients, survivors, and family members. Comparisons were made with a control video on cancer nutrition and diet. Pretest-posttest sample size was 1006, and 669 participants completed a 30-day follow-up impacts assessment. All five family and communication indices increased significantly for WCC…. When compared to the placebo, average pretest-posttest change scores were higher for self-efficacy (775%), family fabric (665%), outside support (189%), and family communication (97%). One month following viewings, WCC…participants reported 30% more conversations about cancer among patients and family members about cancer. A new genre of Entertainment-Education (E-E) was created that triggers positive reactions from audience members. Managing delicate and often complex communication about the trials, tribulations, hopes, and triumphs of cancer journeys is fundamentally important for everyday living. Unique opportunities exist to make WCC… available to national and global audiences, create tailored curricula, and integrate these viewings into educational programs for patients, family members, and care-provider teams across diverse health, corporate, and governmental systems.

    Space Systems Architecture has been expanded into a process by the US Department of Defense for their large scale systems of systems development programs. This paper uses the steps in the process to establishes a framework for Space Elevator systems to be developed and provides a methodology to manage complexity. This new approach to developing a family of systems is based upon three architectural views: Operational View OV), Systems View (SV), and Technical Standards View (TV). The top level view of the process establishes the stages for the development of the first Space Elevator and is called Architectural View - 1, Overview and Summary. This paper will show the guidelines and steps of the process while focusing upon components of the Space Elevator Preliminary Architecture View. This Preliminary Architecture View is presented as a draft starting point for the Space Elevator Project.

This review consolidates previously published findings from our group in order to compare and contrast the spatial profile of neural activity coherence across these distinct cortical dimensions. We focus on studies of ongoing local field potential (LFP data obtained simultaneously from multiple sites in the primary visual cortex in two types of experiments in which electrode contacts were spaced either along the cortical surface or at different laminar positions. These studies demonstrate that across both dimensions the coherence of ongoing LFP fluctuations diminishes as a function of interelectrode distance, although the nature and spatial scale of this falloff is very different. Along the cortical surface, the overall LFP coherence declines gradually and continuously away from a given position. In contrast, across the cortical layers, LFP coherence is discontinuous and compartmentalized as a function of depth. Specifically, regions of high LFP coherence fall into discrete superficial and deep laminar zones, with an abrupt discontinuity between the granular and infragranular layers. This spatial pattern of ongoing LFP coherence is similar when animals are at rest and when they are engaged in a behavioral task. These results point to the existence of partially segregated laminar zones of cortical processing that extend tangentially within the laminar compartments and are thus oriented orthogonal to the cortical columns. We interpret these electrophysiological observations in light of the known anatomical organization of

    Full Text Available The problem of Ebola virus infection is the big global concern. Preparedness for ongoing Ebola virus infection is the topic that should be discussed. In fact, it is necessary to set up a biosecurity system to protect against the present Ebola outbreak. The medical personnel have to prepare for fighting the problem. The management of the present outbreak requires international collaboration and control of cross-border disease transmission is also the big challenge. The good case study is the Hajj scenario.

  10. On the Ongoing Evolution of Very High Frequency Power Supplies

    2013-01-01

    The ongoing demand for smaller and lighter power supplies is driving the motivation to increase the switching frequencies of power converters. Drastic increases however come along with new challenges, namely the increase of switching losses in all components. The application of power circuits used...... in radio frequency transmission equipment helps to overcome those. However those circuits were not designed to meet the same requirements as power converters. This paper summarizes the contributions in recent years in application of very high frequency (VHF) technologies in power electronics, describes...

    Full Text Available The Rare Cancer Network (RCN was formed in the early 1990’s to create a global network that could pool knowledge and resources in the studies of rare malignancies whose infrequency prevented both their study with prospective clinical trials. To date, the RCN has initiated 74 studies resulting in 46 peer reviewed publications. The First International Symposium of the Rare Cancer Network took place in Nice in March of 2014. Status updates and proposals for new studies were heard for fifteen topics. Ongoing studies continue for cardiac sarcomas, thyroid cancers, glomus tumors, and adult medulloblastomas. New proposals were presented at the symposium for primary hepatic lymphoma, solitary fibrous tumors, Rosai-Dorfman disease, tumors of the ampulla of Vater, salivary gland tumors, anorectal melanoma, midline nuclear protein in testes carcinoma, pulmonary lymphoepithelioma-like carcinoma, adenoid cystic carcinoma of the trachea, osteosarcomas of the mandible, and extra-cranial hemangiopericytoma. This manuscript presents the abstracts of those proposals and updates on ongoing studies, as well a brief summary of the vision and future of the RCN.

  12. Visually Evoked Spiking Evolves While Spontaneous Ongoing Dynamics Persist

    Neurons in the primary visual cortex spontaneously spike even when there are no visual stimuli. It is unknown whether the spiking evoked by visual stimuli is just a modification of the spontaneous ongoing cortical spiking dynamics or whether the spontaneous spiking state disappears and is replaced by evoked spiking. This study of laminar recordings of spontaneous spiking and visually evoked spiking of neurons in the ferret primary visual cortex shows that the spiking dynamics does not change: the spontaneous spiking as well as evoked spiking is controlled by a stable and persisting fixed point attractor. Its existence guarantees that evoked spiking return to the spontaneous state. However, the spontaneous ongoing spiking state and the visual evoked spiking states are qualitatively different and are separated by a threshold (separatrix). The functional advantage of this organization is that it avoids the need for a system reorganization following visual stimulation, and impedes the transition of spontaneous spiking to evoked spiking and the propagation of spontaneous spiking from layer 4 to layers 2–3.

    FASTBUS is a modular data and control bus and mechanical packaging standard currently under development. It is being designed to meet the high-speed data acquisition and parallel and distributed processing requirements of the next generation of large-scale physics experiments. It is a multiprocessor system with multiple bus segments which operate independently but link together for passing data. It operates asynchronously to accommodate very high and very low speed devices over long and short paths, using handshake protocols for reliability. It can also operate synchronously without handshakes for transfer to data blocks, at maximum speed. The motivation for developing FASTBUS, its goals, history and organizational structure are summarized. Its features such as bus protocols, sparse data scan capabilities, power supplies and mechanics, bus segmentation and parallel processing structures, etc. are described. European and United States systems being proposed or built using FASTBUS along with hardware and softwa...

    2016-12-01

    Within the multidisciplinary team required to manage people with multiple sclerosis (MS) effectively, the nurse is the central component of coordinated care and support. A 2009 survey led by the European Multiple Sclerosis Platform, an umbrella organization of national MS associations, identified variance and disparity across Europe in the nursing care of MS patients. This led to development of MS Nurse PROfessional, a continuing medical education-accredited modular online learning program endorsed and approved by leading international nursing and professional groups, and people with MS, as a tool to support the evolving role of the European MS nurse. Analysis of participant experience and nurse practice to date has been overwhelmingly positive. Expansion of MS Nurse PRO is underway or planned for future.

    Full Text Available Abstract Background The registration of clinical trials has been promoted to prevent publication bias and increase research transparency. Despite general agreement about the minimum amount of information needed for trial registration, we lack clear guidance on descriptions of non-pharmacologic interventions in trial registries. We aimed to evaluate the quality of registry descriptions of non-pharmacologic interventions assessed in ongoing randomized controlled trials (RCTs of patient education. Methods On 6 May 2009, we searched for all ongoing RCTs registered in the 10 trial registries accessible through the World Health Organization International Clinical Trials Registry Platform. We included trials evaluating an educational intervention (that is, designed to teach or train patients about their own health and dedicated to participants, their family members or home caregivers. We used a standardized data extraction form to collect data related to the description of the experimental intervention, the centers, and the caregivers. Results We selected 268 of 642 potentially eligible studies and appraised a random sample of 150 records. All selected trials were registered in 4 registers, mainly ClinicalTrials.gov (61%. The median [interquartile range] target sample size was 205 [100 to 400] patients. The comparator was mainly usual care (47% or active treatment (47%. A minority of records (17%, 95% CI 11 to 23% reported an overall adequate description of the intervention (that is, description that reported the content, mode of delivery, number, frequency, duration of sessions and overall duration of the intervention. Further, for most reports (59%, important information about the content of the intervention was missing. The description of the mode of delivery of the intervention was reported for 52% of studies, the number of sessions for 74%, the frequency of sessions for 58%, the duration of each session for 45% and the overall duration for 63

    1991-01-01

    The project examines how the results of NASA/DOD research diffuse into the aerospace R&D process, and empirically analyzes the implications of the aerospace knowledge diffusion process. Specific issues considered are the roles played by government technical reports, the recognition of the value of scientific and technical information (STI), and the optimization of the STI aerospace transfer system. Information-seeking habits are assessed for the U.S. aerospace community, the general community, the academic sector, and the international community. U.S. aerospace engineers and scientists use 65 percent of working time to communicate STI, and prefer 'internal' STI over 'external' STI. The isolation from 'external' information is found to be detrimental to U.S. aerospace R&D in general.

    Buchanan-Smith, Margie; Jaspars, Susanne

    2007-03-01

    This paper presents the findings of a study commissioned by World Food Programme (WFP) in early 2006 to enhance understanding of how the conflict in Darfur has affected livelihoods and markets, and of the effects of food aid. The livelihoods of many in Darfur were devastated early on in the conflict, principally through the widespread looting or destruction of assets and highly restricted population movements, which struck at the heart of pre-conflict livelihoods. Livelihood strategies for most people are now restricted, poorly remunerated and often associated with high risk of attack. Patterns of coercion and exploitation have also become entrenched; and markets and trade, the lifeblood of Da fur's economy pre-conflict, severely disrupted. Against this backdrop the impact of food aid on livelihoods in Darfur has been overwhelmingly positive. The paper proposes a number of preconditions for investment in recovery in Darfur, and recommends ways in which livelihoods can be supported in the current context of ongoing conflict.

    After the Berlin UN conference of the signatory states to the Climate Change Convention it seems appropriate to strike an interim balance of the ongoing debate about the global climate change, as it has meanwhile evolved from an issue discussed among experts to an issue of public debate. Such a ''progress report'' seems to be opportune also because doubts are mounting in the face of proclaimed countermeasures. The article therefore reviews and summarizes facts and figures, discussing emissions and concentrations, the physical properties of greenhouse gases, as well as uncertainties of model calculations and of interpretations of measured data. The current situation calls for application of alternative models and concepts, and consideration of natural processes in competition with man-made impacts on the climate within the framework of optimized interpretation, in order to have probabilistic data at hand for decision-making.

    We present updated results from our ongoing analysis of Cassini observations of Jupiter's equatorial meteorology. For two months preceding the spacecraft's closest approach of the planet, the ISS instrument onboard Cassini regularly imaged the atmosphere of Jupiter. We created time-lapse movies from this period that show the complex activity and interactions of the equatorial atmosphere. During this period, hot spots exhibited significant variations in size and shape over timescales of days and weeks. Some of these changes appear to be a result of interactions with passing vortex systems in adjacent latitudes. Strong anticyclonic gyres to the southeast of the dark areas converge with flow from the west and appear to circulate into a hot spot at its southwestern corner.

    U.S. Gulf Coast salt domes, among other geologic structures, currently are being considered for storage of commercial radioactive wastes. A major concern with dome storage of long lived radioactive wastes lies with the possible tectonic movement of the host dome. Any ongoing movement of a salt dome can be monitored with a site specific complementary system of field instrumentation and finite element modelling. Field instrumentation and accompanying finite element analyses for a study dome in northwest Louisiana are described. Site specific data and early experience associated with tiltmeters over the dome are presented. Also, recommendations are made for modifications and extensions of the field instrumentation and finite element modelling appropriate to the specific site under study

    2005-08-01

    The aim of this study was to evaluate the short-term impact of a group crisis intervention for children aged 9-15 years from five refugee camps in the Gaza Strip during ongoing war conflict. Children were selected if they reported moderate to severe posttraumatic stress reactions, and were allocated to group intervention (N=47) encouraging expression of experiences and emotions through storytelling, drawing, free play and role-play; education about symptoms (N=22); or no intervention (N=42). Children completed the CPTSD-RI and the CDI pre- and post-intervention. No significant impact of the group intervention was established on children's posttraumatic or depressive symptoms. Possible explanations of the findings are discussed, including the continuing exposure to trauma and the non-active nature of the intervention.

  7. Energy Colonialism Powers the Ongoing Unnatural Disaster in Puerto Rico

    Full Text Available On September 20, 2017, Hurricane María made landfall in Puerto Rico. Blasting the Caribbean archipelago with 155-mile/h winds, this, in many ways, unnatural disaster exposed the brutal consequences of energy colonialism and an extractivist economy, as well as ongoing and increasing advocacy for decentralized solar infrastructure by many local residents and other renewables supporters. This paper argues that acknowledging colonial power relations and their consequences is essential for studying the interplay of energy systems, environments, and actors. To support this claim, this essay outlines Puerto Rico’s history as a US colony by focusing on key policies and their implications; examines openings for and barriers to decentralized, community solar in Puerto Rico; and concludes by discussing future research directions on just energy transitions and the imperative of uprooting colonialism and agitating for community self-determination and energy justice in these transformations.

    Full Text Available BACKGROUND: With the increasing prevalence of chronic noncommunicable diseases, patient education is becoming important to strengthen disease prevention and control. We aimed to systematically determine the extent to which registered, ongoing randomized controlled trials (RCTs evaluated an educational intervention focus on patient-important outcomes (i.e., outcomes measuring patient health status and quality of life. METHODS: On May 6, 2009, we searched for all ongoing RCTs registered in the World Health Organization International Clinical Trials Registry platform. We used a standardized data extraction form to collect data and determined whether the outcomes assessed were 1 patient-important outcomes such as clinical events, functional status, pain, or quality of life or 2 surrogate outcomes, such as biological outcome, treatment adherence, or patient knowledge. PRINCIPAL FINDINGS: We selected 268 of the 642 potentially eligible studies and assessed a random sample of 150. Patient-important outcomes represented 54% (178 of 333 of all primary outcomes and 46% (286 of 623 of all secondary outcomes. Overall, 69% of trials (104 of 150 used at least one patient-important outcome as a primary outcome and 66% (99 of 150 as a secondary outcome. Finally, for 31% of trials (46 of 150, primary outcomes were only surrogate outcomes. The results varied by medical area. In neuropsychiatric disorders, patient important outcomes represented 84% (51 of 61 of primary outcomes, as compared with 54% (32 of 59 in malignant neoplasm and 18% (4 of 22 in diabetes mellitus trials. In addition, only 35% assessed the long-term impact of interventions (i.e., >6 months. CONCLUSIONS: There is a need to improve the relevance of outcomes and to assess the long term impact of educational interventions in RCTs.

  9. Evidence-Responsiveness and the Ongoing Autonomy of Treatment Preferences.

    Science.gov (United States)

    Weimer, Steven

    2017-06-14

    To be an autonomous agent is to determine one's own path in life. However, this cannot plausibly be seen as a one-off affair. An autonomous agent does not merely set herself on a particular course and then lock the steering wheel in place, so to speak, but must maintain some form of ongoing control over her direction in life-must keep her eyes on the road and her hands on the wheel. Circumstances often change in important and unexpected ways, after all, and it is reasonable to think that a crucial part of autonomy consists of the ability and disposition to recognize and properly respond to such changes. This implies, I contend, that a patient whose initial decision to undergo a given treatment satisfied plausible requirements of autonomy, but who is now unable to recognize that available evidence indicates the need to reconsider her medical situation and options has come to lack autonomy with respect to her desire to continue that treatment. However, and despite its importance with respect to both theoretical understandings of autonomy and applications of the concept to clinical ethics, this ongoing aspect of autonomy has received little attention. This paper aims to go some way toward remedying that. I first critically review two of the few theories of autonomy that do address "evidence-responsiveness" so as to identify and elaborate what I take to be the most promising way in which to account for this aspect of autonomy. After considering and responding to a possible objection to the evidence-responsiveness condition I propose, I conclude by discussing its clinical implications. That condition, I argue, is not merely theoretically sound, but can and should be applied to clinical practice.

    Khan, M E; Mishra, Anurag; Morankar, Sudhakar

    Increase in extramarital sex among youths, gender-based violence, lack of contraceptive knowledge among newly married couples and lack of knowledge of protection against diseases like STIs/HIV are the information and service needs of young people that need to be addressed urgently in order to make them future knowledgeable, responsible, and non-violent partners. In addressing these needs the gatekeepers, including parents, formal and informal community leaders and teachers, play a critical role, by facilitating/hindering access to appropriate and correct information about sexual and reproductive health to young people. The study was conducted in a district of Uttaranchal, India. The specific objective was to understand the social context and gatekeepers' views on family planning and sexual and reproductive health needs of young men. Thirty-two in-depth interviews and four focus group discussions were conducted with parents, formal and informal community leaders, teachers, and selected development officials. The findings indicate that gatekeepers are worried about rapid changes in the aspiration, expectation, and behavior of young men. Most of them were seriously concerned about the increasing drinking habit, use of drugs, and changing values of sexuality leading to various risk behaviors among young men. They felt that many of these changes are consequences of wider societal changes, rising aspirations, explosion of electronic media, and globalization of a new youth culture where extramarital sex, alcohol consumption, and violence are expressions of different facets of masculinity and symbols of the affluent class. Overall, there was a feeling that TV/films and their peers now influence more the socialization of young people and parents are losing control in guidance and mentoring of their children.

    2013-01-01

    The "zograscope" is a "visual aid" (commonly known as "optical machine" in the 18th century) invented in the mid-18th century, and in general use until the early 20th century. It was intended to view single pictures (thus not stereographic pairs) with both eyes. The optics approximately eliminates the physiological cues (binocular disparity, vergence, accommodation, movement parallax, and image blur) that might indicate the flatness of the picture surface. The spatial structure of pictorial space is due to the remaining pictorial cues. As a consequence, many (or perhaps most) observers are aware of a heightened "plasticity" of the pictorial content for zograscopic as compared with natural viewing. We discuss the optics of the zograscope in some detail. Such an analysis is not available in the literature, whereas common "explanations" of the apparatus are evidently nonsensical. We constructed a zograscope, using modern parts, and present psychophysical data on its performance.

  12. Remote viewing.

    Scott, C

    1988-04-15

    Remote viewing is the supposed faculty which enables a percipient, sited in a closed room, to describe the perceptions of a remote agent visiting an unknown target site. To provide convincing demonstration of such a faculty poses a range of experimental and practical problems, especially if feedback to the percipient is allowed after each trial. The precautions needed are elaborate and troublesome; many potential loopholes have to be plugged and there will be strong temptations to relax standards, requiring exceptional discipline and dedication by the experimenters. Most reports of remote viewing experiments are rather superficial and do not permit assessment of the experimental procedures with confidence; in many cases there is clear evidence of particular loopholes left unclosed. Any serious appraisal of the evidence would have to go beyond the reports. Meanwhile the published evidence is far from compelling, and certainly insufficient to justify overthrow of well-established scientific principles.

    Last year saw very good progress at ESO's Paranal Observatory , the site of the Very Large Telescope (VLT). The third and fourth 8.2-m Unit Telescopes, MELIPAL and YEPUN had "First Light" (cf. PR 01/00 and PR 18/00 ), while the first two, ANTU and KUEYEN , were busy collecting first-class data for hundreds of astronomers. Meanwhile, work continued towards the next phase of the VLT project, the combination of the telescopes into the VLT Interferometer. The test instrument, VINCI (cf. PR 22/00 ) is now being installed in the VLTI Laboratory at the centre of the observing platform on the top of Paranal. Below is a new collection of video sequences and photos that illustrate the latest developments at the Paranal Observatory. The were obtained by the EPR Video Team in December 2000. The photos are available in different formats, including "high-resolution" that is suitable for reproduction purposes.

    Full Text Available The ongoing education training for teachers can be done through different models that could only report or also accompany the process of implementing innovations. The training through reflection processes is presented as essential to make changes in the classroom; also, if it is done collectively with other teachers or between centers, transformations will not only occur in the classroom, but in the whole context. One way leading to a collaborative ongoing education is through action research groups, considering a set of ethical practices whose characteristics allow participants to be trained according to their needs, and through support with other teachers, in order to transform the context. The research we present here is framed in a Teaching Innovation Project, University of Valladolid, through which teachers from three schools that have been trained in inclusive education through action research implementing in their classrooms interactive groups. This collaborative process played by teachers themselves has changed the thinking of teachers, their classroom and their educational contexts in which they work.

  16. Water rights of the head reach farmers in view of a water supply scenario at the extension area of the Babai Irrigation Project, Nepal

    Science.gov (United States)

    Adhikari, B.; Verhoeven, R.; Troch, P.

    The farmer managed irrigation systems (FMIS) represent those systems which are constructed and operated solely by the farmers applying their indigenous technology. The FMIS generally outperform the modern irrigation systems constructed and operated by the government agencies with regard to the water delivery effectiveness, agricultural productivity etc., and the presence of a sound organization responsible to run the FMIS, often referred to as the ‘social capital’, is the key to this success. This paper studies another important aspect residing in the FMIS: potentials to expand the irrigation area by means of their proper rehabilitation and modernization. Taking the case study of the Babai Irrigation Project in Nepal, it is demonstrated that the flow, which in the past was used to irrigate the 5400 ha area covered by three FMIS, can provide irrigation to an additional 8100 ha in the summer, 4180 ha vegetables in the winter and 1100 ha maize in the spring season after the FMIS rehabilitation. The “priority water rights” of the FMIS part have been evaluated based on relevant crop water requirement calculations and is found to be equal to 85.4 million m 3 per year. Consequently, the dry season irrigation strategy at the extension area could be worked out based on the remaining flow. By storing the surplus discharge of the monsoon and autumn in local ponds, and by consuming them in dry period combined with nominal partial irrigation practice, wheat and mustard can be cultivated over about 4000 ha of the extension area. Furthermore, storage and surface irrigation both contribute to the groundwater recharge. The conjunctive use of ground, surface and harvested water might be the mainstream in the future for a sustainable irrigation water management in the region.

    An ongoing collaborative project, currently being piloted in 12 Wiltshire primary schools, is described. The aim is to provide a means of identifying potentially dyslexic children by the end of Key Stage 1 (Year 2) with a view to early intervention. The causal links identified by research between phonological skills and literacy development are taken as the theoretical basis of an initial screening procedure, and an intervention package is implemented for identified children. Those demonstrating persistent difficulties one year later are further assessed over a school term using an assessment package designed to identify those children showing a dyslexic profile. Further intervention is then planned and implemented.

    Germany's Commission on the Disposal of High-level Radioactive Waste, which was set up in compliance with the country's Repository Site Selection Act, has been tasked with drawing up criteria for a site selection process and evaluating the act by mid-2016. Lessons can be learned from the failed Asse and Gorleben repository projects, and the selection process should take these into account. Transparency and widespread public participation are crucial to reaching a broad consensus on the issue of permanent disposal. The commission must also produce a plan for avoiding and correcting errors during the selection process. Key elements of a selection process already exist or can be adapted to reflect the current state of the art with relatively little effort. Working from this basis, it should be possible to achieve a result that can end the ongoing conflict surrounding permanent disposal.

    During the past year the Scottish Nuclear had been working to win increased public acceptance of nuclear power in Scotland. Since then it has stepped up the PR campaign activities - and has had a very successful year. But much has still to be done. The programme 'Come and See' which was introduced in the Spring of 1991. was developed and extended introducing a Talks Service and a mobile exhibition as two new features. At the same time the Torness Power Station Visitors' Centre was opened. In 1992 a visitor's centre was opened at Hunterston Power Station. By the end of November 1992, there was almost 28,000 visitors - an increase of 48% compared to the previous year. An extensive 1.9 million pound television and newspaper advertising campaign was also mounted during the summer months. So it has been a particularly busy year and more than modestly successful. Another arm of Come and See is 'Talkabout' - the Talks Service. In 1992 members of staff gave 187 talks all over Scotland - to over 5,000 people. In the Spring of 1992 a Mobile Exhibition was also introduced. It tours the whole of Scotland. In all there have been 62 venues, a large variety of events. Over 30,000 people have visited the exhibition since March. To enhance all these Programmes a variety of literature, videos, promotional items, and static exhibition material are prepared. These have all been developed since 1990 and are kept updated on an on-going basis.

    2017-01-01

    Full Text Available Corrosion of steel reinforcement is the main cause of deterioration in reinforced concrete structures. It can result in cracking and spalling of the concrete cover. After the damaged cover is repaired, reinforcement corrosion might continue and even accelerate. While the development of the corrosion cell is difficult to control, the damage can be possibly delayed and controlled by use of a suitable repair material. The lattice fracture model is used in this paper to investigate the performance of strain hardening cementitious composite (SHCC in concrete repair systems exposed to ongoing corrosion. Numerical results were verified by experimental tests when SHCC, nonreinforced material (repair mortar, and commercial repair mortar are used as repair materials. In experiments, reinforcement bars (surrounded by a repair material were exposed to accelerated corrosion tests. The influence of the substrate surface preparation, the type of repair material, the interface, and the substrate strength on the resulting damage and failure mode of repair systems are discussed. In general, SHCC repair enables distributed cracking with small crack widths, up to several times smaller compared to repair mortar. Furthermore, more warning signs prior to the final failure are present in the SHCC repair system.

    Until recently, leprosy had been prominent in 33 countries worldwide, and Vietnam was ranked among the top 14 endemic countries. The leprosy situation in Vietnam was reviewed as a sample of the worldwide ongoing medical and social struggle to assess the need for continued support for leprosy control activities and for social programs of integration of leprosy victims into the community. A search was conducted of official Vietnamese publications, World Health Organization documents, major electronic databases, and popular leprosy Web sites; as well, notes from visits to local leprosy clinics and interviews with health workers were checked. Important achievements were realized through national determination and international collaboration. In contrast with the impressive performance statistics at the national level, and despite strong government efforts for leprosy control, the results obtained at the province-city and district-commune levels still exhibit deficiencies in case detection, treatment, and socioeconomic integration of leprosy victims. The struggle to eliminate such a complex and destructive infectious disease as leprosy does not end with the cure. Deep-seated medical and social problems remain. These problems are best solved through community-based approaches.

    Observed tree mortality of the last decades has shown that the vulnerable forest ecosystems are especially affected by the recurrent, long lasting droughts, heat waves and their consequences. From all site conditions climate is changing the fastest, in this way it can be the largest threatening factor in the 21st century. Beyond climate, soil characteristics are playing an important influencing role. Until now, silvicultural technologies and species preferences of many countries are prescribed by binding regulation based on climate conditions that are assumed to be constant over time. Therefore the aim of our research was to investigate the ongoing and projected change of site conditions that are considered to be of primary importance in terms of tree species selection. For a case study region in Hungary (Keszthely Mountains, near to Lake Balaton) long-term climate tendencies have been determined for the period 1961-2100, as well as a detailed soil sample analysis has been carried out including ~100 sites. Results show a 0.5 degree increase of temperature and a 6-7 % decrease of the precipitation amount for the summer months in the last decades. For the future, significant warming and drying of summers is expected. Decrease of the summer precipitation sum can exceed 25 % until the end of the century, probability of extreme hot days may increase. These tendencies together with the unfavourable soil conditions and biotic damages can be the reason of the ongoing forest dieback. One of the characteristic soil type of the region is rendzina with a thin topsoil layer and an unfavourable water holding capacity. These properties are limiting the amount of available water for plants, especially in case of intense precipitation events. Black pine stands planted on rendzinas after many years of grazing; therefore erosion may have played a significant role. Not only microclimate conditions but also soil types show a large diversity within a relatively small distance. However

  6. Hydrate Evolution in Response to Ongoing Environmental Shifts

    Natural gas hydrates have the potential to become a vital domestic clean-burning energy source. However, past changes in environmental conditions have caused hydrates to become unstable and trigger both massive submarine landslides and the development of crater-like pockmarks, thereby releasing methane into the overlying seawater and atmosphere, where it acts as a powerful greenhouse gas. This project was designed to fill critical gaps in our understanding of domestic hydrate resources and improve forecasts for their response to environmental shifts. Project work can be separated into three interrelated components, each involving the development of predictive mathematical models. The first project component concerns the role of sediment properties on the development and dissociation of concentrated hydrate anomalies. To this end, we developed numerical models to predict equilibrium solubility of methane in twophase equilibrium with hydrate as a function of measureable porous medium characteristics. The second project component concerned the evolution of hydrate distribution in heterogeneous reservoirs. To this end, we developed numerical models to predict the growth and decay of anomalies in representative physical environments. The third project component concerned the stability of hydrate-bearing slopes under changing environmental conditions. To this end, we developed numerical treatments of pore pressure evolution and consolidation, then used "infinite-slope" analysis to approximate the landslide potential in representative physical environments, and developed a "rate-and-state" frictional formulation to assess the stability of finite slip patches that are hypothesized to develop in response to the dissociation of hydrate anomalies. The increased predictive capabilities that result from this work provide a framework for interpreting field observations of hydrate anomalies in terms of the history of environmental forcing that led to their development.

    Social context plays an important role in human communication. Depending on the nature of the source, the same communication signal might be processed in fundamentally different ways. However, the selective modulation (or "gating") of the flow of neural information during communication is not fully understood. Here, we use multivoxel pattern analysis (MVPA) and multivoxel connectivity analysis (MVCA), a novel technique that allows to analyse context-dependent changes of the strength interregional coupling between ensembles of voxels, to examine how the human brain differentially gates content-specific sensory information during ongoing perception of communication signals. In a simulated electronic communication experiment, participants received two alternative text messages during fMRI ("happy" or "sad") which they believed had been sent either by their real-life friend outside the scanner or by a computer. A region in the dorsal medial prefrontal cortex (dmPFC) selectively increased its functional coupling with sensory-content encoding regions in the visual cortex when a text message was perceived as being sent by the participant's friend, and decreased its functional coupling with these regions when a text message was perceived as being sent by the computer. Furthermore, the strength of neural encoding of content-specific information of text messages in the dmPFC was modulated by the social tie between the participant and her friend: the more of her spare time a participant reported to spend with her friend the stronger was the neural encoding. This suggests that the human brain selectively gates sensory information into the relevant network for processing the mental states of others, depending on the source of the communication signal.

    Due to prioritisation in the initial trauma care, non-life threatening injuries can be overlooked or temporally neglected. Polytrauma patients in particular might be at risk for delayed diagnosed injuries (DDI). Studies that solely focus on DDI in polytrauma patients are not available. Therefore the aim of this study was to analyze DDI and determine risk factors associated with DDI in polytrauma patients. In this single centre retrospective cohort study, patients were considered polytrauma when the Injury Severity Score was ≥ 16 as a result of injury in at least 2 body regions. Adult polytrauma patients admitted from 2007 until 2012 were identified. Hospital charts were reviewed to identify DDI. 1416 polytrauma patients were analyzed of which 12% had DDI. Most DDI were found during initial hospital admission after tertiary survey (63%). Extremities were the most affected regions for all types of DDI (78%) with the highest intervention rate (35%). Most prevalent DDI were fractures of the hand (54%) and foot (38%). In 2% of all patients a DDI was found after discharge, consisting mainly of injuries other than a fracture. High energy trauma mechanism (OR 1.8, 95% CI 1.2-2.7), abdominal injury (OR 1.5, 95% CI 1.1-2.1) and extremity injuries found during initial assessment (OR 2.3, 95% CI 1.6-3.3) were independent risk factors for DDI. In polytrauma patients, most DDI were found during hospital admission but after tertiary survey. This demonstrates that the tertiary survey should be an ongoing process and thus repeated daily in polytrauma patients. Most frequent DDI were extremity injuries, especially injuries of the hand and foot. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full text: To describe ongoing development of software to support the review of radiotherapy treatment planning system (TPS) data. The 'SWAN' software program was conceived in 2000 and initially developed for the RADAR (TROG 03.04) prostate radiotherapy trial. Validation of the SWAN program has been occurring via implementation by TROG in support of multiple clinical trials. Development has continued and the SWAN software program is now supported by modular components which comprise the 'SW AN system'. This provides a comprehensive set of tools for the review, analysis and archive of TPS exports. The SWAN system has now been used in support of over 20 radiotherapy trials and to review the plans of over 2,000 trial participants. The use of the system for the RADAR trial is now culminating in the derivation of dose-outcomes indices for prostate treatment toxicity. Newly developed SWAN tools include enhanced remote data archive/retrieval, display of dose in both relative and absolute modes, and interfacing to a Matlab-based add-on ('VAST') that allows quantitative analysis of delineated volumes including regional overlap statistics for multi-observer studies. Efforts are continuing to develop the SWAN system in the context of international collaboration aimed at harmonising the quality-assurance activities of collaborative trials groups. Tools such as the SWAN system are essential for ensuring the collection of accurate and reliable evidence to guide future radiotherapy treatments. One of the principal challenges of developing such a tool is establishing a development path that will ensure its validity and applicability well into the future.

  10. Early markers of ongoing action-effect learning

    Full Text Available Acquiring knowledge about the relationship between stimulus conditions, one’s own actions, and the resulting consequences or effects, is one prerequisite for intentional action. Previous studies have shown that such contextualized associations between actions and their effects (S-R-E associations can be picked up very quickly. The present study examined how such weakly practiced associations might affect overt behavior during the process of initial learning and during subsequent retrieval, and how these two measures are inter-related. We examined incidental (S-R-E learning in the context of trial-and-error S-R learning and in the context of instruction-based S-R learning. Furthermore, as a control condition, common outcome (CO learning blocks were included in which all responses produced one common sound effect, hence precluding differential (S-R-E learning. Post-learning retrieval of R-E associations was tested by re-using previously produced sound effects as novel imperative stimuli combined with actions that were either compatible or incompatible with the previously encountered R-E mapping. The central result was that the size of the compatibility effect could be predicted by the size of relative response slowing during ongoing learning in the preceding acquisition phase, both in trial-and-error learning and in instruction-based learning. Importantly, this correlation was absent for the common outcome control condition, precluding accounts based on unspecific factors. Instead, the results suggest that differential outcomes are ‘actively’ integrated into action planning and that this takes additional planning time. We speculate that this might be especially true for weakly practiced (S-R-E associations before an initial goal-directed action mode transitions into a more stimulus-based action mode.

    Sarcopenia research may be hampered by the heterogeneity of populations and outcome measures used in clinical studies. The aim of this study was to describe the inclusion/exclusion criteria and outcome measures used in ongoing research in sarcopenia. All active intervention studies registered in the World Health Organization with the keyword sarcopenia were included. Study design, type of intervention, inclusion/exclusion criteria and outcome measures were registered and classified. In April 2014, 151 studies on sarcopenia were registered in the WHO database. One hundred twenty-three were intervention studies. Most trials (94.3 %) were single centre and randomized (93.5 %), 51.2 % were double blind. Nutritional interventions (36.6 %), physical exercise (12.2 %) or both (19.5 %) were the most common interventions tested. Only 54.4 % included subjects of both genders, and 46.3 % had an upper age limit. Definition of the target populations was heterogeneous, with 57.7 % including healthy subjects and none using recent definitions of sarcopenia. Lifestyle and the degree of physical activity of subjects were not described or considered in most cases (79.7 %). Subjects with cardiovascular, neuropsychiatric or metabolic disorders and those with physical disability were usually excluded. Muscle mass and muscle strength were the primary outcome variables in 28.5 and 29.5 % of studies and physical performance in 19.5 %, but only 4.1 % used the three variables used the three of them. An additional 26.8 % used biological outcome variables. Little information and agreement existed in the way muscle and physical performance parameters were measured. We found a large heterogeneity in trial design, definition of populations and outcome measures in present research.

  12. Rootstock breeding in Prunus species: Ongoing efforts and new challenges

    Directory of Open Access Journals (Sweden)

    Felipe Gainza

    2015-08-01

    Full Text Available The current global agricultural challenges imply the need to generate new technologies and farming systems. In this context, rootstocks are an essential component in modern agriculture. Most currently used are those clonally propagated and there are several ongoing efforts to develop this type of plant material. Despite this tendency, lesser number of rootstock breeding programs exists in comparison to the large number of breeding programs for scion cultivars. In the case of rootstocks, traits evaluated in new selection lines are quite different: From the agronomic standpoint vigor is a key issue in order to establish high-density orchards. Other important agronomic traits include compatibility with a wide spectrum of cultivars from different species, good tolerance to root hypoxia, water use efficiency, aptitude to extract or exclude certain soil nutrients, and tolerance to soil or water salinity. Biotic stresses are also important: Resistance/tolerance to pests and diseases, such as nematodes, soil-borne fungi, crown gall, bacterial canker, and several virus, viroids, and phytoplasms. In this sense, the creation of new rootstocks at Centro de Estudios Avanzados en Fruticultura (CEAF offers an alternative to stone fruit crop, particularly in Chile, where just a few alternatives are commercially available, and there are site-specific problems. The implementation of molecular markers in order to give support to the phenotypic evaluation of plant breeding has great potential assisting the selection of new genotypes of rootstocks. Marker-Assisted Selection (MAS can shorten the time required to obtain new cultivars and can make the process more cost-effective than selection based exclusively on phenotype, but more basic research is needed to well understood the molecular and physiological mechanisms behind the studied trait.

    Full Text Available An audiovisual interface equipped with a projector, an inclina-tion sensor, and a distance sensor for zoom control has been developed that enables a user to selectively view and listen to specific performers in a video-taped group performance. Dubbed Concert Viewing Headphones, it has both image and sound processing functions. The image processing extracts the portion of the image indicated by the user and projects it free of distortion on the front and side walls. The sound processing creates imaginary microphones for those performers without one so that the user can hear the sound from any performer. Testing using images and sounds captured using a fisheye-lens camera and 37 lavalier microphones showed that sound locali-zation was fastest when an inverse square function was used for the sound mixing and that the zoom function was useful for locating the desired sound performance.

  18. Risk Stratification in Differentiated Thyroid Cancer: An Ongoing Process

    Directory of Open Access Journals (Sweden)

    Gal Omry-Orbach

    2016-01-01

    Full Text Available Thyroid cancer is an increasingly common malignancy, with a rapidly rising prevalence worldwide. The social and economic ramifications of the increase in thyroid cancer are multiple. Though mortality from thyroid cancer is low, and most patients will do well, the risk of recurrence is not insignificant, up to 30%. Therefore, it is important to accurately identify those patients who are more or less likely to be burdened by their disease over years and tailor their treatment plan accordingly. The goal of risk stratification is to do just that. The risk stratification process generally starts postoperatively with histopathologic staging, based on the AJCC/UICC staging system as well as others designed to predict mortality. These do not, however, accurately assess the risk of recurrence/persistence. Patients initially considered to be at high risk may ultimately do very well yet be burdened by frequent unnecessary monitoring. Conversely, patients initially thought to be low risk, may not respond to their initial treatment as expected and, if left unmonitored, may have higher morbidity. The concept of risk-adaptive management has been adopted, with an understanding that risk stratification for differentiated thyroid cancer is dynamic and ongoing. A multitude of variables not included in AJCC/UICC staging are used initially to classify patients as low, intermediate, or high risk for recurrence. Over the course of time, a response-to-therapy variable is incorporated, and patients essentially undergo continuous risk stratification. Additional tools such as biochemical markers, genetic mutations, and molecular markers have been added to this complex risk stratification process such that this is essentially a continuum of risk. In recent years, additional considerations have been discussed with a suggestion of pre-operative risk stratification based on certain clinical and/or biologic characteristics. With the increasing prevalence of thyroid cancer but

    To investigate the dependence of microcalcification cluster detectability on tomographic scan angle, angular increment, and number of projection views acquired at digital breast tomosynthesis ( DBT digital breast tomosynthesis ). A prototype DBT digital breast tomosynthesis system operated in step-and-shoot mode was used to image breast phantoms. Four 5-cm-thick phantoms embedded with 81 simulated microcalcification clusters of three speck sizes (subtle, medium, and obvious) were imaged by using a rhodium target and rhodium filter with 29 kV, 50 mAs, and seven acquisition protocols. Fixed angular increments were used in four protocols (denoted as scan angle, angular increment, and number of projection views, respectively: 16°, 1°, and 17; 24°, 3°, and nine; 30°, 3°, and 11; and 60°, 3°, and 21), and variable increments were used in three (40°, variable, and 13; 40°, variable, and 15; and 60°, variable, and 21). The reconstructed DBT digital breast tomosynthesis images were interpreted by six radiologists who located the microcalcification clusters and rated their conspicuity. The mean sensitivity for detection of subtle clusters ranged from 80% (22.5 of 28) to 96% (26.8 of 28) for the seven DBT digital breast tomosynthesis protocols; the highest sensitivity was achieved with the 16°, 1°, and 17 protocol (96%), but the difference was significant only for the 60°, 3°, and 21 protocol (80%, P .99). The conspicuity of subtle and medium clusters with the 16°, 1°, and 17 protocol was rated higher than those with other protocols; the differences were significant for subtle clusters with the 24°, 3°, and nine protocol and for medium clusters with 24°, 3°, and nine; 30°, 3°, and 11; 60°, 3° and 21; and 60°, variable, and 21 protocols (P tomosynthesis provided higher sensitivity and conspicuity than wide-angle DBT digital breast tomosynthesis for subtle microcalcification clusters. © RSNA, 2014.

  1. The ongoing saga surrounding the velocity fluctuations in sedimentation

    Science.gov (United States)

    Brenner, Michael P.

    2002-11-01

    Particles moving through a viscous fluid interact with each other, because each individual particle drags fluid along with it, which then pulls on other particles. In a low Reynolds number sediment, such hydrodynamic interactions are extremely strong, even when the particles are well separated. Despite more than a century of research, the character of the particle motions in a dilute suspension of heavy particles is highly controversial: In 1985, Caflisch and Luke presented an extremely simple argument indicating that the velocity fluctuations in such a sediment should diverge with the system size. Experiments have mainly contradicted this conclusion, leading to the hope that there is a (perhaps universal) ''screening mechanism'' controlling the size of the fluctuations. In this lecture I will review the history of this problem, and then present the results of our recent research which indicates that the velocity fluctuations are highly nonuniversal and system size dependent, depending subtley on both the shape of the container holding the sediment and any particle stratification that develops during an experiment. Experiments, numerical simulations and theory are presented that quantitatively support this point of view. This work is in collaboration with P. J. Mucha and the experimental group of D. A. Weitz: (S. Tee, S. Manley and L. Cippelletti).

  2. The ongoing educational anomaly of earth science placement

    The geosciences have traditionally been viewed with less "aCademic prTstige" than other science curricula. Among the results of this perception are depressed K-16 enrollments, Earth Science assignments to lower-performing students, and relegation of these classes to sometimes under-qualified educators, all of which serve to confirm the widely-held misconceptions. An Earth Systems course developed at San Jos??e State University demonstrates the difficulty of a standard high school Earth science curriculum, while recognizing the deficiencies in pre-college Earth science education. Restructuring pre-college science curricula so that Earth Science is placed as a capstone course would greatly improve student understanding of the geosciences, while development of Earth systems courses that infuse real-world and hands-on learning at the college level is critical to bridging the information gap for those with no prior exposure to the Earth sciences. Well-crafted workshops for pre-service and inservice teachers of Earth Science can heIp to reverse the trends and unfortunate "sTatus" in geoscience education.

    footwall part of the exposed West Cycladic Detachment System in the extreme SW of the island. The cause of the change from BGM in the east to YBM in the west is enigmatic. A primary sedimentary variation is unlikely, as it is parallel to the stretching direction; syn-tectonic dissolution seems more likely, but implies a massive fluid flow through the rocks. The confusion between BGM and YBM is seen elsewhere, with, for example, the map showing BGM changing to YBM across a normal fault, with little apparent offset of the marble boundary. Clearly, the map of de Smeth (1975), although very good in general, needs careful reworking. More important, it is potentially obscuring significant large-scale structures by mapping the same marble as two different lithostratigraphic units. Work is ongoing in the area.

    Past and current exploitation of parallel computing in High Energy Physics is summarized and a list of R & D projects in this area is presented. The applicability of new parallel hardware and software to physics problems is investigated, in the light of the requirements for computing power of LHC experiments and the current trends in the computer industry. Four main themes are discussed (possibilities for a finer grain of parallelism; fine-grain communication mechanism; usable parallel programming environment; different programming models and architectures, using standard commercial products). Parallel computing technology is potentially of interest for offline and vital for real time applications in LHC. A substantial investment in applications development and evaluation of state of the art hardware and software products is needed. A solid development environment is required at an early stage, before mainline LHC program development begins.

    The main objective of this review is to explore the wide and expanding field of new clinical trials in IPF. Recent trials have confirmed the efficacy of the approved drugs pirfenidone and nintedanib; nonetheless, the discovery of new biological pathways has opened new horizons in this field. Areas covered: New strategies against matrix deposition are under study and so is for the role of immunity and autoimmunity. Recent advances in the use of stem cells are opening new possibilities for the recovery of damaged lung tissues. The role of microbioma is under investigation in order to evaluate the use of antibiotics in IPF treatment. Analysing all the new and the upcoming clinical trials, we are trying to offer a comprehensive view of the emerging new frontiers in the treatment of IPF. Expert commentary: The key points for the ongoing and upcoming clinical trials will be to avoid previous mistakes and to choose carefully both study populations and efficacy endpoints. The exciting possibility to enrol patients with progressive lung fibrosis, both idiopathic and not, could be a next step forward. How the existing therapies will fit in a futurist scenario of personalized medicine is still a challenge.

    In less than three decades, the concept “cerebellar neurocognition” has evolved from a mere afterthought to an entirely new and multifaceted area of neuroscientific research. A close interplay between three main strands of contemporary neuroscience induced a substantial modification of the traditional view of the cerebellum as a mere coordinator of autonomic and somatic motor functions. Indeed, the wealth of current evidence derived from detailed neuroanatomical investigations, functional neuroimaging studies with healthy subjects and patients and in-depth neuropsychological assessment of patients with cerebellar disorders shows that the cerebellum has a cardinal role to play in affective regulation, cognitive processing, and linguistic function. Although considerable progress has been made in models of cerebellar function, controversy remains regarding the exact role of the “linguistic cerebellum” in a broad variety of nonmotor language processes. This consensus paper brings together a range of different viewpoints and opinions regarding the contribution of the cerebellum to language function. Recent developments and insights in the nonmotor modulatory role of the cerebellum in language and some related disorders will be discussed. The role of the cerebellum in speech and language perception, in motor speech planning including apraxia of speech, in verbal working memory, in phonological and semantic verbal fluency, in syntax processing, in the dynamics of language production, in reading and in writing will be addressed. In addition, the functional topography of the linguistic cerebellum and the contribution of the deep nuclei to linguistic function will be briefly discussed. As such, a framework for debate and discussion will be offered in this consensus paper. PMID:24318484

    The basic results and methods of projective and non-Euclidean geometry are indispensable for the geometer, and this book--different in content, methods, and point of view from traditional texts--attempts to emphasize that fact. Results of special theorems are discussed in detail only when they are needed to develop a feeling for the subject or when they illustrate a general method. On the other hand, an unusual amount of space is devoted to the discussion of the fundamental concepts of distance, motion, area, and perpendicularity.Topics include the projective plane, polarities and conic sectio

    In the spirit of collaboration and reciprocity, James Rattling Leaf of Sinte Gleska University on the Rosebud Reservation of South Dakota will present recent developments, experiences, insights and a vision for education in Indian Country. As a thirty-year young institution, Sinte Gleska University is founded by a strong vision of ancestral leadership and the values of the Lakota Way of Life. Sinte Gleska University (SGU) has initiated the development of a Geospatial Education Curriculum project. NativeView: A Geospatial Curriculum for Native Nation Building is a two-year project that entails a disciplined approach towards the development of a relevant Geospatial academic curriculum. This project is designed to meet the educational and land management needs of the Rosebud Lakota Tribe through the utilization of Geographic Information Systems (GIS), Remote Sensing (RS) and Global Positioning Systems (GPS). In conjunction with the strategy and progress of this academic project, a formal presentation and demonstration of the SGU based Geospatial software RezMapper software will exemplify an innovative example of state of the art information technology. RezMapper is an interactive CD software package focused toward the 21 Lakota communities on the Rosebud Reservation that utilizes an ingenious concept of multimedia mapping and state of the art data compression and presentation. This ongoing development utilizes geographic data, imagery from space, historical aerial photography and cultural features such as historic Lakota documents, language, song, video and historical photographs in a multimedia fashion. As a tangible product, RezMapper will be a project deliverable tool for use in the classroom and to a broad range of learners.

    Full Text Available Abstract Background Reducing low-density lipoprotein cholesterol (LDL-C is associated with reduced risk for major coronary events. Despite statin efficacy, a considerable proportion of statin-treated hypercholesterolemic patients fail to reach therapeutic LDL-C targets as defined by guidelines. This study compared the efficacy of ezetimibe added to ongoing statins with doubling the dose of ongoing statin in a population of Taiwanese patients with hypercholesterolemia. Methods This was a randomized, open-label, parallel-group comparison study of ezetimibe 10 mg added to ongoing statin compared with doubling the dose of ongoing statin. Adult Taiwanese hypercholesterolemic patients not at optimal LDL-C levels with previous statin treatment were randomized (N = 83 to ongoing statin + ezetimibe (simvastatin, atorvastatin or pravastatin + ezetimibe at doses of 20/10, 10/10 or 20/10 mg or doubling the dose of ongoing statin (simvastatin 40 mg, atorvastatin 20 mg or pravastatin 40 mg for 8 weeks. Percent change in total cholesterol, LDL-C, high-density lipoprotein cholesterol (HDL-C and triglycerides, and specified safety parameters were assessed at 4 and 8 weeks. Results At 8 weeks, patients treated with statin + ezetimibe experienced significantly greater reductions compared with doubling the statin dose in LDL-C (26.2% vs 17.9%, p = 0.0026 and total cholesterol (20.8% vs 12.2%, p = 0.0003. Percentage of patients achieving treatment goal was greater for statin + ezetimibe (58.6% vs doubling statin (41.2%, but the difference was not statistically significant (p = 0.1675. The safety and tolerability profiles were similar between treatments. Conclusion Ezetimibe added to ongoing statin therapy resulted in significantly greater lipid-lowering compared with doubling the dose of statin in Taiwanese patients with hypercholesterolemia. Studies to assess clinical outcome benefit are ongoing. Trial registration Registered at ClinicalTrials.gov: NCT00652327

    Full Text Available Even in the absence of sensory inputs, cortical and thalamic neurons can show structured patterns of ongoing spontaneous activity, whose origins and functional significance are not well understood. We use computer simulations to explore the conditions under which spontaneous activity emerges from a simplified model of multiple interconnected thalamocortical columns linked by long-range, top-down excitatory axons, and to examine its interactions with stimulus-induced activation. Simulations help characterize two main states of activity. First, spontaneous gamma-band oscillations emerge at a precise threshold controlled by ascending neuromodulator systems. Second, within a spontaneously active network, we observe the sudden "ignition" of one out of many possible coherent states of high-level activity amidst cortical neurons with long-distance projections. During such an ignited state, spontaneous activity can block external sensory processing. We relate those properties to experimental observations on the neural bases of endogenous states of consciousness, and particularly the blocking of access to consciousness that occurs in the psychophysical phenomenon of "inattentional blindness," in which normal subjects intensely engaged in mental activity fail to notice salient but irrelevant sensory stimuli. Although highly simplified, the generic properties of a minimal network may help clarify some of the basic cerebral phenomena underlying the autonomy of consciousness.

    The National Oceanic and Atmospheric Administration's National Geodetic Survey (NGS) mission is "to define, maintain and provide access to the National Spatial Reference System (NSRS) to meet our nation's economic, social, and environmental needs." The NSRS is an assemblage of geophysical and geodetic models, tools, and data, with the most-visible components being the North American Datum of 1983 (NAD83) and the North American Vertical Datum of 1988 (NAVD88), which together provide a consistent spatial reference framework for myriad geospatial applications and positioning requirements throughout the United States. The NGS is engaged in an ongoing and comprehensive multi-year project of modernizing the NSRS, a makeover necessitated by technological developments and user accuracy requirements, all with a goal of providing a modern, accurate, accessible, and globally aligned national positioning framework exploiting the substantial power and utility of the Global Navigation Satellite System - of both today and tomorrow. The modernized NSRS will include four new-generation geometric terrestrial reference frames (replacing NAD83) and a technically unprecedented geopotential datum (replacing NAVD88), all to be released in 2022 (anticipated). This poster/presentation will describe the justification for this modernization effort and will update the status and planned evolution of the NSRS as 2022 draws ever closer. Also discussed will be recent developments, including the publication of "blueprint" documents addressing technical details of various facets of the modernized NSRS and a continued series of public Geospatial Summits. Supporting/ancillary projects such as Gravity for the Redefinition of the American Vertical Datum (GRAV-D), which will result in the generation of a highly accurate gravimetric geoid - or definitional reference surface (zero elevation) - for the future geopotential datum, and Geoid Slope Validation Surveys (GSVS), which are exploring the achievable

  2. Prospective memory and intraindividual variability in ongoing task response times in an adult lifespan sample: the role of cue focality.

    Ihle, Andreas; Ghisletta, Paolo; Kliegel, Matthias

    2017-03-01

    To contribute to the ongoing conceptual debate of what traditional mean-level ongoing task (OT) costs tell us about the attentional processes underlying prospective memory (PM), we investigated costs to intraindividual variability (IIV) in OT response times as a potentially sensitive indicator of attentional processes. Particularly, we tested whether IIV in OT responses may reflect controlled employment of attentional processes versus lapses of controlled attention, whether these processes differ across adulthood, and whether it is moderated by cue focality. We assessed 150 individuals (19-82 years) in a focal and a nonfocal PM condition. In addition, external measures of inhibition and working memory were assessed. In line with the predictions of the lapses-of-attention/inefficient-executive-control account, our data support the view that costs to IIV in OT trials of PM tasks reflect fluctuations in the efficiency of executive functioning, which was related to failures in prospective remembering, particularly in nonfocal PM tasks, potentially due to their increased executive demands. The additional value of considering costs to IIV over and beyond traditional mean-level OT costs in PM research is discussed.

  4. View synthesis using parallax invariance

    Science.gov (United States)

    Dornaika, Fadi

    2001-06-01

    View synthesis becomes a focus of attention of both the computer vision and computer graphics communities. It consists of creating novel images of a scene as it would appear from novel viewpoints. View synthesis can be used in a wide variety of applications such as video compression, graphics generation, virtual reality and entertainment. This paper addresses the following problem. Given a dense disparity map between two reference images, we would like to synthesize a novel view of the same scene associated with a novel viewpoint. Most of the existing work is relying on building a set of 3D meshes which are then projected onto the new image (the rendering process is performed using texture mapping). The advantages of our view synthesis approach are as follows. First, the novel view is specified by a rotation and a translation which are the most natural way to express the virtual location of the camera. Second, the approach is able to synthesize highly realistic images whose viewing position is significantly far away from the reference viewpoints. Third, the approach is able to handle the visibility problem during the synthesis process. Our developed framework has two main steps. The first step (analysis step) consists of computing the homography at infinity, the epipoles, and thus the parallax field associated with the reference images. The second step (synthesis step) consists of warping the reference image into a new one, which is based on the invariance of the computed parallax field. The analysis step is working directly on the reference views, and only need to be performed once. Examples of synthesizing novel views using either feature correspondences or dense disparity map have demonstrated the feasibility of the proposed approach.

Advanced LabVIEW Labs presents a series of chapters devoted to not only introducing the reader to LabVIEW, but also to the concepts necessary for writing a successful computer pro- gram. Each chapter is an assignment for the student and is suitable for a ten week course. The first topic introduces the while loop and waveform chart VI'S. After learning how to launch LabVIEW, the student then leans how to use LabVIEW functions such as sine and cosine. The beauty of thk and subsequent chapters, the student is introduced immediately to computer-based instruction by learning how to display the results in graph form on the screen. At each point along the way, the student is not only introduced to another LabVIEW operation, but also to such subjects as spread sheets for data storage, numerical integration, Fourier transformations', curve fitting algorithms, etc. The last few chapters conclude with the purpose of the learning module, and that is, com- puter-based instrumentation. Computer-based laboratory projects such as analog-to-digital con- version, digitizing oscilloscopes treated. Advanced Lab VIEW Labs finishes with a treatment on GPIB interfacing and finally, the student is asked to create an operating VI for temperature con- trol. This is an excellent text, not only as an treatise on LabVIEW but also as an introduction to computer programming logic. All programmers, who are struggling to not only learning how interface computers to instruments, but also trying understand top down programming and other programming language techniques, should add Advanced Lab-VIEW Labs to their computer library

The vehicle for this transformation is Enterprise SRS which presents a new, strategic view of SRS as a united endeavor for 'all things nuclear' as opposed to a group of distinct and separate entities with individual missions and organizations. Key among the Enterprise SRS strategic initiatives is the integration of research into facilities in conjunction with ongoing missions to provide researchers from other national laboratories, academic institutions, and commercial entities the opportunity to demonstrate their technologies in a relevant environment and scale prior to deployment. To manage that integration of research demonstrations into site facilities, The DOE Savannah River Operations Office, Savannah River Nuclear Solutions, and the Savannah River National Laboratory (SRNL) have established a center for applied nuclear materials processing and engineering research (hereafter referred to as the Center). The key objective of this initiative is to bridge the gap between promising transformational nuclear materials management advancements and large-scale deployment of the technology by using SRS assets (e.g. facilities, staff, and property) for those critical engineering-scale demonstrations necessary to assure the successful deployment of new technologies. The Center will coordinate the demonstration of R and D technologies and serve as the interface between the engineering-scale demonstration and the R and D programs, essentially providing cradle-to-grave support to the R and D team during the demonstration. While the initial focus of the Center will be on the effective use of SRS assets for these demonstrations, the Center also will work with research teams to identify opportunities to perform R and D demonstrations at other facilities. Unique to this approach is the fact

    2014-01-01

    Remembering to perform an action in the future, called prospective memory, often shows age-related differences in favor of young adults when tested in the laboratory. Recently Smith, Horn, and Bayen (2012; Aging, Neuropsychology, and Cognition, 19, 495) embedded a PM task in an ongoing color-matching task and manipulated the difficulty of the ongoing task by varying the number of colors on each trial of the task. Smith et al. found that age-related differences in PM performance (lower PM performance for older adults relative to young adults) persisted even when older adults could perform the ongoing task as well or better than the young adults. The current study investigates a possible explanation for the pattern of results reported by Smith et al. by including a manipulation of task emphasis: for half of the participants the prospective memory task was emphasize, while for the other half the ongoing color-matching task was emphasized. Older adults performed a 4-color version of the ongoing color-matching task, while young adults completed either the 4-color or a more difficult 6-color version of the ongoing task. Older adults failed to perform as well as the young adults on the prospective memory task regardless of task emphasis, even when older adults were performing as well or better than the young adults on the ongoing color-matching task. The current results indicate that the lack of an effect of ongoing task load on prospective memory task performance is not due to a perception that one or the other task is more important than the other.

  11. Management of Ground and Groundwater Contamination on a Compact Site Constrained by Ongoing Activities

    Sellafield Site is a compact and complex site which since the 1940's has been home to a range of facilities associated with the production and reprocessing of fissile material. The site contains the UK equivalent of the Chicago Pile-1 reactor, Hanford B Reactor, Rocky Flats Buildings 771 and 774, West Valley Main Process Plant Building, Savannah River Vitrification Plant, Savannah River MOX Plant, Savannah River F Canyon, Hanford 222 Analytical Laboratory, Savannah River K-, L-, and P-Basins, and the Fort St. Vrain Reactor all in an area of approximately 1000 acres. Spent fuel reprocessing is still undertaken on site; however waste management and decommissioning activities are of increasing importance. These include the emptying and removal of fragile ponds and silos containing significant radioactive inventories, the decommissioning of reactors (including the world's first commercial reactor for power generation and the Windscale Piles, the site of a reactor fire in the late 1950's) and the construction of a new generation of vitrification and encapsulation plants. Leaks, spills and on-site disposals during the site's industrial lifetime have resulted in a legacy of fission products and other radionuclides in the ground and groundwater. Volumes of contaminated ground have been estimated as being as much as 18 million m 3 and an estimated below ground inventory of approximately 1.8 E16 Bq. These have all occurred within close proximity to a range of receptors including farm land and the sea. The cramped nature of the facilities on site, overlapping source terms and ongoing decommissioning, waste management and operating activities all raise significant challenges in the management and remediation of contaminated land and groundwater. The strategy to address these challenges includes: 1. Data collection, management and interpretation. The congested nature of the site and the age of some of the monitoring facilities has resulted in particular difficulties. For

  12. Enhancing multi-view autostereoscopic displays by viewing distance control (VDC)

    Conventional multi-view displays spatially interlace various views of a 3D scene and form appropriate viewing channels. However, they only support sufficient stereo quality within a limited range around the nominal viewing distance (NVD). If this distance is maintained, two slightly divergent views are projected to the person's eyes, both covering the entire screen. With increasing deviations from the NVD the stereo image quality decreases. As a major drawback in usability, the manufacturer so far assigns this distance. We propose a software-based solution that corrects false view assignments depending on the distance of the viewer. Our novel approach enables continuous view adaptation based on the calculation of intermediate views and a column-bycolumn rendering method. The algorithm controls each individual subpixel and generates a new interleaving pattern from selected views. In addition, we use color-coded test content to verify its efficacy. This novel technology helps shifting the physically determined NVD to a user-defined distance thereby supporting stereopsis. The recent viewing positions can fall in front or behind the NVD of the original setup. Our algorithm can be applied to all multi-view autostereoscopic displays — independent of the ascent or the periodicity of the optical element. In general, the viewing distance can be corrected with a factor of more than 2.5. By creating a continuous viewing area the visualized 3D content is suitable even for persons with largely divergent intraocular distance — adults and children alike — without any deficiency in spatial perception.

    Ongoing child welfare services are put in place after completion of the initial maltreatment investigation when there is a perceived need to mitigate the risk of future harm. The knowledge of how clinical, worker, and organizational characteristics interact with this decision to provide ongoing child welfare services is not well integrated in the research literature. Using secondary data from the Canadian Incidence Study of Reported Child Abuse and Neglect-2008, this study's primary objective is to understand the relationship of clinical, worker, and organizational characteristics to the decision to transfer a case to ongoing child welfare services and their relative contribution to the transfer decision in Canada. Findings indicate that several clinical level variables are associated with families receiving ongoing services. Additionally, organizational factors, such as type of services offered by the organization and the number of employee support programs available to workers, significantly predicted the decision to transfer a case to ongoing services. While no worker factors, such as education, amount of training, experience, or caseload, were associated with ongoing service receipt, the intraclass correlation coefficient of the final three-level parsimonious model indicated substantial clustering at the worker level. Results indicate that Canadian child welfare workers make decisions differently based on factors not available in the current study and that what would be deemed as important worker characteristics do not necessarily predict this outcome. Findings and implications for future research are discussed. Copyright © 2018 Elsevier Ltd. All rights reserved.

    2015-07-01

    Germany's Commission on the Disposal of High-level Radioactive Waste, which was set up in compliance with the country's Repository Site Selection Act, has been tasked with drawing up criteria for a site selection process and evaluating the act by mid-2016. Lessons can be learned from the failed Asse and Gorleben repository projects, and the selection process should take these into account. Transparency and widespread public participation are crucial to reaching a broad consensus on the issue of permanent disposal. The commission must also produce a plan for avoiding and correcting errors during the selection process. Key elements of a selection process already exist or can be adapted to reflect the current state of the art with relatively little effort. Working from this basis, it should be possible to achieve a result that can end the ongoing conflict surrounding permanent disposal.

    1982-01-01

    The technique of the 60 degree supine oblique view is described together with anatomic skeletal studies of this projection. The view is convenient for emergency room radiography and useful in other clinical radiography. The view separates widely the anterior and posterior portions of the vertebrae in a side to side projection. This makes for an elongated but detailed view of the articular processes, pedicles, and intervertebral foramina. In the cadavar specimen and clinically the view is shown to be useful in delineating fracture deformities of the articular process and visualizing constriction of the intervertebral foramen superiorly. Encroachment of the foramen superiorly is likely to compromise the emerging nerve root in this area

    Local nerve inflammation (neuritis) leads to ongoing activity and axonal mechanical sensitivity (AMS) along intact nociceptor axons and disrupts axonal transport. This phenomenon forms the most feasible cause of radiating pain, such as sciatica. We have previously shown that axonal transport disruption without inflammation or degeneration also leads to AMS but does not cause ongoing activity at the time point when AMS occurs, despite causing cutaneous hypersensitivity. However, there have been no systematic studies of ongoing activity during neuritis or noninflammatory axonal transport disruption. In this study, we present the time course of ongoing activity from primary sensory neurons following neuritis and vinblastine-induced axonal transport disruption. Whereas 24% of C/slow Aδ-fiber neurons had ongoing activity during neuritis, few (disruption of axonal transport without inflammation does not lead to ongoing activity in sensory neurons, including nociceptors, but does cause a rapid and transient development of AMS. Because it is proposed that AMS underlies mechanically induced radiating pain, and a transient disruption of axonal transport (as previously reported) leads to transient AMS, it follows that processes that disrupt axonal transport, such as neuritis, must persist to maintain AMS and the associated symptoms. NEW & NOTEWORTHY Many patients with radiating pain lack signs of nerve injury on clinical examination but may have neuritis, which disrupts axonal transport. We have shown that axonal transport disruption does not induce ongoing activity in primary sensory neurons but does cause transient axonal mechanical sensitivity. The present data complete a profile of key axonal sensitivities following axonal transport disruption. Collectively, this profile supports that an active peripheral process is necessary for maintained axonal sensitivities.

    The purpose of this paper is to describe staff experiences in an on-going improvement project regarding patients with ureteral stones. A qualitative descriptive study based on eight group interviews and 48 narratives, was performed. Data were analysed using qualitative content analysis. Trustworthiness was ensured by using a well-documented improvement process method during six months. The results formed three categories: an absent comprehensive view; complexity; and vulnerability within the organisation. A holistic perspective regarding urological care at the micro-, meso- and macro-levels is needed to improve planning and caring processes. This study includes one team (six members, different health professionals) within the same urology department. Results show that staff need information, such as guidelines and support throughout the improvement work to deliver high-quality care. Moreover, there is a need for evidence-based guidelines at national level to support improvement work. Healthcare staff need to pay attention to all team member needs to improve urological care. Organisational and managerial aspect are needed to support clear and common goals regarding healthcare improvement work. Urological improvement projects, generally, are lacking, which is why this study is important to improve nephrolithiasis patient care.

  20. Ongoing EEG phase as a trial-by-trial predictor of perceptual and attentional variability

    Directory of Open Access Journals (Sweden)

    Rufin eVanRullen

    2011-04-01

    Full Text Available Even in well-controlled laboratory environments, apparently identical repetitions of an experimental trial can give rise to highly variable perceptual outcomes and behavioral responses. This variability is generally discarded as a reflection of intrinsic noise in neuronal systems. However, part of this variability may be accounted for by trial-by-trial fluctuations of the phase of ongoing oscillations at the moment of stimulus presentation. For example, the phase of an EEG oscillation reflecting the rapid waxing and waning of sustained attention can predict the perception of a subsequent visual stimulus at threshold. Similar ongoing periodicities account for a portion of the trial-by-trial variability of visual reaction times. We review the available experimental evidence linking ongoing EEG phase to perceptual and attentional variability, and the corresponding methodology. We propose future tests of this relation, and discuss the theoretical implications for understanding the neuronal dynamics of sensory perception.

  1. Synchronizing XPath Views

    Pedersen, Dennis; Pedersen, Torben Bach

    2004-01-01

    The increasing availability of XML-based data sources, e.g., for publishing data on the WWW, means that more and more applications (data consumers) rely on accessing and using XML data. Typically, the access is achieved by defining views over the XML data, and accessing data through these views....... However, the XML data sources are often independent of the data consumers and may change their schemas without notification, invalidating the XML views defined by the data consumers. This requires the view definitions to be updated to reflect the new structure of the data sources, a process termed view...... synchronization. XPath is the most commonly used language for retrieving parts of XML documents, and is thus an important cornerstone for XML view definitions. This paper presents techniques for discovering schema changes in XML data sources and synchronizing XPath-based views to reflect these schema changes...

    NASA's Mars Exploration Rover Spirit used its navigation camera to take the images combined into this 210-degree view of the rover's surroundings during the 1,861st to 1,863rd Martian days, or sols, of Spirit's surface mission (March 28 to 30, 2009). The center of the scene is toward the south-southwest. East is on the left. West-northwest is on the right. The rover had driven 22.7 meters (74 feet) southwestward on Sol 1861 before beginning to take the frames in this view. The drive brought Spirit past the northwestern corner of Home Plate. In this view, the western edge of Home Plate is on the portion of the horizon farthest to the left. A mound in middle distance near the center of the view is called 'Tsiolkovsky' and is about 40 meters (about 130 feet) from the rover's position. This view is presented as a cylindrical projection with geometric seam correction.

    A challenge to all remedial approaches for contaminated sediments is the continued influx of contaminants from uncontrolled sources following remediation. We investigated the effects of ongoing contamination in mesocosms employing sediments remediated by different types of active and passive caps and in-situ treatment. Our hypothesis was that the sequestering agents used in active caps and in situ treatment will bind elements (arsenic, chromium, cadmium, cobalt, copper, nickel, lead, selenium, and zinc) from ongoing sources thereby reducing their bioavailability and protecting underlying remediated sediments from recontamination. Most element concentrations in surface water remained significantly lower in mesocosms with apatite and mixed amendment caps than in mesocosms with passive caps (sand), uncapped sediment, and spike solution throughout the 2520 h experiment. Element concentrations were significantly higher in Lumbriculus variegatus from untreated sediment than in Lumbriculus from most active caps. Pearson correlations between element concentrations in Lumbriculus and metal concentrations in the top 2.5 cm of sediment or cap measured by diffusive gradient in thin films (DGT) sediment probes were generally strong (as high as 0.98) and significant (p < 0.05) for almost all tested elements. Metal concentrations in both Lumbriculus and sediment/cap were lowest in apatite, mixed amendment, and activated carbon treatments. These findings show that some active caps can protect remediated sediments by reducing the bioavailable pool of metals/metalloids in ongoing sources of contamination. - Graphical abstract: Conventional methods of remediating contaminated sediments may be inadequate for the protection of benthic organisms when ongoing sources of contamination are present.

    2010-07-01

    The lateralization of 250-ms trains of brief noise bursts was measured using an acoustic pointing technique. Stimuli were designed to assess the contribution of the interaural time delay (ITD) of the onset binaural burst relative to that of the ITDs in the ongoing part of the train. Lateralization was measured by listeners' adjustments of the ITD of a pointer stimulus, a 50-ms burst of noise, to match the lateral position of the target train. Results confirmed previous reports of lateralization dominance by the onset burst under conditions in which the train is composed of frozen tokens and the ongoing part contains multiple ambiguous interaural delays. In contrast, lateralization of ongoing trains in which fresh noise tokens were used for each set of two alternating (left-leading/right-leading) binaural pairs followed the ITD of the first pair in each set, regardless of the ITD of the onset burst of the entire stimulus and even when the onset burst was removed by gradual gating. This clear lateralization of a long-duration stimulus with ambiguous interaural delay cues suggests precedence mechanisms that involve not only the interaural cues at the beginning of a sound, but also the pattern of cues within an ongoing sound.

    As an approach to manage power demand-side resources, DSM plays an important role in electric power system. Though DSM was introduced into China in the early 1990s, its benefits have been underutilized. Using literature study, interview methods and three data sources, this paper examines the likely impacts of China's on-going power sector reform on its DSM. It finds that the major constraints to DSM in China are the insufficient and improper market-based DSM mechanism, grid companies’ low motivations for DSM due to their traditional business model, the underdeveloped energy service industry, and electricity end-users’ low motivation for DSM. China's on-going power sector reform will change power transmission and distribution pricing and grid companies’ business model and introduce competition into retail-side. Drawing on these findings, it is concluded that the likely impacts of the new reform on DSM are: governments may attach more importance to DSM; grid companies may have more motivations for DSM investment; electricity end-users’ motivations for DSM may be both enhanced and dampened; electricity retailers’ motivations for DSM may be dampened; demand response application may be enhanced, and more DSM business models may be developed. Finally, policy implications are provided. - Highlights: • Mechanism of and constraints to DSM in China are examined. • China’s on-going power sector reform is overviewed. • DSM is likely to be enhanced under China's on-going power sector reform. • Policy implications are provided.

    Not all euploid embryos implant, necessitating additional tools to select viable blastocysts in preimplantation genetic screening cycles. In this retrospective cohort study, 129 consecutive patients who underwent 129 single euploid blastocyst transfers in cryopreserved embryo transfer cycles were included. All embryos were individually cultured in a time-lapse incubator from intracytoplasmic sperm injection up to trophoectoderm biopsy. Twenty-three time-lapse morphokinetic variables were tested among patients with (n = 68) or without (n = 61) ongoing pregnancy. All 23 time-lapse morphokinetic variables, apart from duration of blastulation (tB-tSB), were comparable between patients with or without ongoing pregnancy. Duration of blastulation was significantly shorter in patients with ongoing pregnancy (8.1 ± 3.2 versus 9.5 ± 3.4 h; P = 0.014); shorter duration of blastulation remained an independent predictor for ongoing pregnancy, when tested by logistic regression analysis (OR 0.81; 95% CI 0.70 to 0.93). One important limitation of this study, and a reason for caution, is the use of multiple comparisons, which can lead to differences at the 0.05 level simply by chance or random variation. Nonetheless, the study suggests that when more than one euploid blastocyst is available, priority might be given to those with a shorter duration of blastulation.

    Along with the development of petawatt class laser systems, the interaction between high power lasers and matter flourished an extensive research, with high-interest applications like: laser nuclear physics, proton radiography or cancer therapy. The new ELI-NP (Extreme Light Infrastructure - Nuclear Physics) petawatt laser facility, with 10PW and ~ 1023W/cm2 beam intensity, is one of the innovative projects that will provide novel research of fundamental processes during light-matter interaction. As part of the ELI-NP facility, Targets Laboratory will provide the means for in-house manufacturing and characterization of the required targets (mainly solid ones) for the experiments, in addition to the research activity carried out in order to develop novel target designs with improved performances. A description of the Targets Laboratory with the main pieces of equipment and their specifications are presented. Moreover, in view of the latest progress in the target design, one of the proposed strategies for the forthcoming experiments at ELI-NP is also described, namely: ultra-thin patterned foil of diamond-like carbon (DLC) coated with a carbon-based ultra-low density layer. The carbon foam which behaves as a near-critical density plasma, will allow the controlled-shaping of the laser pulse before the main interaction with the solid foil. Particular emphasis will be directed towards the target's design optimization, by simulation tests and tuning the key-properties (thickness/length, spacing, density foam, depth, periodicity etc.) which are expected to have a crucial effect on the laser-matter interaction process.

  12. The relationship between event-based prospective memory and ongoing task performance in chimpanzees (Pan troglodytes.

    Directory of Open Access Journals (Sweden)

    Theodore A Evans

    Full Text Available Prospective memory is remembering to do something at a future time. A growing body of research supports that prospective memory may exist in nonhuman animals, but the methods used to test nonhuman prospective memory differ from those used with humans. The current work tests prospective memory in chimpanzees using a method that closely approximates a typical human paradigm. In these experiments, the prospective memory cue was embedded within an ongoing task. Tokens representing food items could be used in one of two ways: in a matching task with pictures of items (the ongoing task or to request a food item hidden in a different location at the beginning of the trial. Chimpanzees had to disengage from the ongoing task in order to use the appropriate token to obtain a higher preference food item. In Experiment 1, chimpanzees effectively matched tokens to pictures, when appropriate, and disengaged from the ongoing task when the token matched the hidden item. In Experiment 2, performance did not differ when the target item was either hidden or visible. This suggested no effect of cognitive load on either the prospective memory task or the ongoing task, but performance was near ceiling, which may have contributed to this outcome. In Experiment 3, we created a more challenging version of the task. More errors on the matching task occurred before the prospective memory had been carried out, and this difference seemed to be limited to the hidden condition. This finding parallels results from human studies and suggests that working memory load and prospective memory may have a similar relationship in nonhuman primates.

  13. Extended reviewing or the role of potential siting cantons in the ongoing Swiss site selection procedure ('Sectoral Plan')

    2014-01-01

    The disposition of nuclear waste in Switzerland has a long-standing and sinuous history reflecting its complex socio-technical nature (Flueeler, 2006). Upon the twofold failure to site a repository for low- and intermediate-level radioactive waste at Wellenberg during the 1990's and 2000's, it was recognised that the respective site selections had not been fully transparent. The Swiss government, the Federal Council, accepted the lesson and, after an extensive nationwide consultation at that, established a new site selection process 'from scratch': a systematic, stepwise, traceable, fair and binding procedure with a safety-first approach, yet extensively participatory. The so-called Sectoral Plan for Deep Geological Repositories guarantees the inclusion of the affected and concerned cantons and communities, as well as the relevant authorities in neighbouring countries from an early stage (Swiss Nuclear Energy Act, 2003; BFE, 2008). This contribution shares experience and insights in the ongoing procedure from a cantonal point of view that is an intermediate position between national needs and regional concerns, and with technical regulatory expertise between highly specialised experts and involved publics.

    Coordinated views have proven critical to the development of effective visualization environments. This results from the fact that a single view or representation of the data cannot show all of the intricacies of a given data set. Additionally, users will often need to correlate more data parameters than can effectively be integrated into a single visual display. Typically, development of multiple-linked views results in an adhoc configuration of views and associated interactions. The hierarchical model we are proposing is geared towards more effective organization of such environments and the views they encompass. At the same time, this model can effectively integrate much of the prior work on interactive and visual frameworks. Additionally, we expand the concept of views to incorporate perceptual views. This is related to the fact that visual displays can have information encoded at various levels of focus. Thus, a global view of the display provides overall trends of the data while focusing in on individual elements provides detailed specifics. By integrating interaction and perception into a single model, we show how one impacts the other. Typically, interaction and perception are considered separately, however, when interaction is being considered at a fundamental level and allowed to direct/modify the visualization directly we must consider them simultaneously and how they impact one another.

    The study evaluates the effectiveness of an ongoing, community-based breast cancer prevention program offered by a local social services agency in the Washington, DC, metropolitan area. Korean American women who participated in this breast cancer prevention program were compared with those who did not participate in their knowledge, attitude, and screening behaviors. The study found that the intervention group was more knowledgeable on breast cancer and related services and reported more positive attitudes toward breast cancer screening services than the comparison group. The participants in the intervention group were also more likely to plan to receive a mammogram than those in the comparison group. However, significant differences were not observed in the two groups in their intention to receive a clinical breast examination. The study findings suggest that an ongoing, community-based breast cancer prevention program can be an effective method of addressing breast cancer prevention disparities observed among Korean American women.

    Childhood asthma has shown variable associations with children's physical activity. Neighborhood walkability captures community features that promote walking and is protective against some chronic conditions, such as obesity and diabetes. We evaluated associations between home neighborhood walkability and incident and ongoing childhood asthma. In this population-based cohort study, we used prospectively collected administrative healthcare data for the Province of Ontario housed at the Institute for Clinical Evaluative Sciences. We followed an administrative data cohort of 326,383 Toronto children born between 1997 and 2003, inclusive, until ages 8-15 years. Home neighborhood walkability quintile was measured using a validated walkability index with four dimensions: population density, dwelling density, access to retail and services, and street connectivity. Incident asthma was defined by time of entry into the validated Ontario Asthma Surveillance Information System database, which requires two outpatient visits for asthma within two consecutive years or any hospitalization for asthma and follows children with asthma longitudinally starting at any age. Associations between walkability and incident asthma were examined using Cox proportional hazards models. Associations between ongoing asthma and walkability in each year of life were examined using generalized linear mixed models. Twenty-one percent of children (n = 69,628) developed incident asthma and were followed longitudinally in the Ontario Asthma Surveillance Information System database. Low birth home neighborhood walkability was associated with an increased incidence of asthma (hazard ratio, 1.11; 95% confidence interval, 1.08-1.14). Among children with asthma, low walkability in a given year of a child`s life was associated with greater odds of ongoing asthma in the same year (odds ratio, 1.12; 95% confidence interval, 1.09-1.14). Children living in neighborhoods with low walkability were at increased

  9. Differential effects of ongoing EEG beta and theta power on memory formation.

    Directory of Open Access Journals (Sweden)

    Sebastian Scholz

    Full Text Available Recently, elevated ongoing pre-stimulus beta power (13-17 Hz at encoding has been associated with subsequent memory formation for visual stimulus material. It is unclear whether this activity is merely specific to visual processing or whether it reflects a state facilitating general memory formation, independent of stimulus modality. To answer that question, the present study investigated the relationship between neural pre-stimulus oscillations and verbal memory formation in different sensory modalities. For that purpose, a within-subject design was employed to explore differences between successful and failed memory formation in the visual and auditory modality. Furthermore, associative memory was addressed by presenting the stimuli in combination with background images. Results revealed that similar EEG activity in the low beta frequency range (13-17 Hz is associated with subsequent memory success, independent of stimulus modality. Elevated power prior to stimulus onset differentiated successful from failed memory formation. In contrast, differential effects between modalities were found in the theta band (3-7 Hz, with an increased oscillatory activity before the onset of later remembered visually presented words. In addition, pre-stimulus theta power dissociated between successful and failed encoding of associated context, independent of the stimulus modality of the item itself. We therefore suggest that increased ongoing low beta activity reflects a memory promoting state, which is likely to be moderated by modality-independent attentional or inhibitory processes, whereas high ongoing theta power is suggested as an indicator of the enhanced binding of incoming interlinked information.

    Quality control (QC) in medical imaging is an ongoing process and not just a series of infrequent evaluations of medical imaging equipment. The QC process involves designing and implementing a QC program, collecting and analyzing data, investigating results that are outside the acceptance levels for the QC program, and taking corrective action to bring these results back to an acceptable level. The QC process involves key personnel in the imaging department, including the radiologist, radiologic technologist, and the qualified medical physicist (QMP). The QMP performs detailed equipment evaluations and helps with oversight of the QC program, the radiologic technologist is responsible for the day-to-day operation of the QC program. The continued need for ongoing QC in digital radiography has been highlighted in the scientific literature. The charge of this task group was to recommend consistency tests designed to be performed by a medical physicist or a radiologic technologist under the direction of a medical physicist to identify problems with an imaging system that need further evaluation by a medical physicist, including a fault tree to define actions that need to be taken when certain fault conditions are identified. The focus of this final report is the ongoing QC process, including rejected image analysis, exposure analysis, and artifact identification. These QC tasks are vital for the optimal operation of a department performing digital radiography

  11. Magma accumulation or second boiling - Investigating the ongoing deformation field at Montserrat, West Indies

    Collinson, Amy; Neuberg, Jurgen; Pascal, Karen

    2016-04-01

    For over 20 years, Soufriere Hills Volcano, Montserrat has been in a state of volcanic unrest. Intermittent periods of dome building have been punctuated by explosive eruptions and dome collapse events, endangering the lives of the inhabitants of the island. The last episode of active magma extrusion was in February 2010, and the last explosive event (ash venting) in March 2012. Despite a lack of eruptive activity recently, the volcano continues to emit significant volumes of SO2 and shows an ongoing trend of island inflation. Through the aid of three-dimensional numerical modelling, using a finite element method, we explore the potential sources of the ongoing island inflation. We consider both magmatic (dykes and chamber) and tectonic sources. Whilst a magmatic source suggests the possibility for further eruption, a tectonic source may indicate cessation of volcanic activity. We show that a magmatic source is the most likely scenario, and illustrate the effect of different sources (shapes, characters and depths) on the surface displacement. Furthermore, through the inclusion of topographic data, we investigate how the topography may affect the displacement pattern at the surface. We investigate the conflicting scenarios of magma chamber resupply versus second boiling - crystallisation-induced degassing. Based on numerical modelling results, we suggest the required pressurisation is too high for crystallisation-induced degassing to be the dominant process - thereby suggesting magma accumulation may be ongoing. However, we show that second boiling may be a contributing factor, particularly when taking into account the local tectonics and regional stretching.

It is unclear whether this activity is merely specific to visual processing or whether it reflects a state facilitating general memory formation, independent of stimulus modality. To answer that question, the present study investigated the relationship between neural pre-stimulus oscillations and verbal memory formation in different sensory modalities. For that purpose, a within-subject design was employed to explore differences between successful and failed memory formation in the visual and auditory modality. Furthermore, associative memory was addressed by presenting the stimuli in combination with background images. Results revealed that similar EEG activity in the low beta frequency range (13-17 Hz) is associated with subsequent memory success, independent of stimulus modality. Elevated power prior to stimulus onset differentiated successful from failed memory formation. In contrast, differential effects between modalities were found in the theta band (3-7 Hz), with an increased oscillatory activity before the onset of later remembered visually presented words. In addition, pre-stimulus theta power dissociated between successful and failed encoding of associated context, independent of the stimulus modality of the item itself. We therefore suggest that increased ongoing low beta activity reflects a memory promoting state, which is likely to be moderated by modality-independent attentional or inhibitory processes, whereas high ongoing theta power is suggested as an indicator of the enhanced binding of incoming interlinked information.

  13. Ongoing Evaluation of Clinical Ethics Consultations as a Form of Continuous Quality Improvement.

    2017-01-01

    Ongoing evaluation of a clinical ethics consultation service (ECS) allows for continuous quality improvement, a process-based, data-driven approach for improving the quality of a service. Evaluations by stakeholders involved in a consultation can provide real-time feedback about what is working well and what might need to be improved. Although numerous authors have previously presented data from research studies on the effectiveness of clinical ethics consultation, few ECSs routinely send evaluations as an ongoing component of their everyday clinical activities. The primary purpose of this article is to equip and encourage others to engage in ongoing evaluation of their own ECS. Toward that end, the following resources are shared: (1) the survey tool used to gather the evaluation data, (2) the procedure used to elicit and collate responses, and (3) how the resulting data are used to support continuous quality improvement and justify the continued financial support of the ECS to hospital administration.

    A subset of HIV-1-infected patients known as elite controllers or suppressors (ES) control the virus naturally. We have previously demonstrated sequence discordance between proviral and plasma gag clones in ES, much of which can be attributed to selective pressure from the host (J. R. Bailey, T. M. Williams, R. F. Siliciano, and J. N. Blankson, J. Exp. Med. 203:1357-1369, 2006). However, it is not clear whether ongoing viral replication continues in ES once the control of viremia has been established or whether selective pressure impacts this evolution. The cytotoxic T-lymphocyte (CTL) response in ES often targets Gag and frequently is superior to that of HIV-1 progressors, partially due to the HLA class I alleles B*57/5801 and B*27, which are overrepresented in ES. We therefore examined longitudinal plasma and proviral gag sequences from HLA-B*57/5801 and -B*27 ES. Despite the highly conserved nature of gag, we observed clear evidence of evolution in the plasma virus, largely due to synonymous substitutions. In contrast, evolution was rare in proviral clones, suggesting that ongoing replication in ES does not permit the significant reseeding of the latent reservoir. Interestingly, there was little continual evolution in CTL epitopes, and we detected de novo CTL responses to autologous viral mutants. Thus, some ES control viremia despite ongoing replication and evolution. PMID:20444904

    A consultation for emergency contraception (EC) gives way to an opportunity to provide women with an ongoing effective method of contraception. A review of the case notes of women seeking EC from a large family planning clinic in Edinburgh, Scotland, was conducted to determine what percentage of women were provided with an effective method of ongoing contraception. Case notes of 460 women presenting for EC over a 2-year period were reviewed. Women were of mean age 26 years (range 15-49 years) and presented because they had used no contraception (47%), experienced condom failure (42%) or missed oral contraceptive pills (9%). Only 2% (n=11) were given an intrauterine device for EC. All women who had missed contraceptive pills prior to taking EC opted to continue this method. Only 23% (n=89) of women using no method or condoms at EC received supplies of an effective contraceptive method (pills, patch, injectable). Two thirds (n=263) of the women chose condoms for ongoing contraception. Research is required to develop strategies to improve the uptake of effective contraception after EC.

  20. Enhancing Safety Culture in Complex Nuclear Industry Projects

    2016-01-01

    This paper presents an on-going research project “Management principles and safety culture in complex projects” (MAPS), supported by the Finnish Research Programme on Nuclear Power Plant Safety 2015-2018. The project aims at enhancing safety culture and nuclear safety by supporting high quality execution of complex projects in the nuclear industry. Safety-critical industries are facing new challenges, related to increased outsourcing and complexity in technology, work tasks and organizational structures (Milch and Laumann, 2016). In the nuclear industry, new build projects, as well as modernisation projects are temporary undertakings often carried out by networks of companies. Some companies may have little experience in the nuclear industry practices or consideration of specific national regulatory requirements. In large multinational subcontractor networks, the challenge for assuring nuclear safety arises partly from the need to ensure that safety and quality requirements are adequately understood and fulfilled by each partner. Deficient project management practices and unsatisfactory nuclear safety culture in project networks have been recognised as contributing factors to these challenges (INPO, 2010). Prior evidence indicated that many recent major projects have experienced schedule, quality and financial challenges both in the nuclear industry (STUK, 2011) and in the non-nuclear domain (Ahola et al., 2014; Brady and Davies, 2010). Since project delays and quality issues have been perceived mainly as economic problems, project management issues remain largely understudied in safety research. However, safety cannot be separated from other performance aspects if a systemic view is applied. Schedule and quality challenges may reflect deficiencies in coordination, knowledge and competence, distribution of roles and responsibilities or attitudes among the project participants. It is increasingly understood that the performance of the project network in all

    Detailed rheological analyses of lubricants are carried out with a view to the temperature dependence of the viscosity functions. Two sliding bearings of similar design but made of different materials were tested on a test bench after lubrication with an oil of the SAE grade 10W-40 diluted with increasing concentrations of rapeseed oil methyl ester. The results were analyzed and compared with the bearings characteristics calculated according to DIN 31652. The measurements were found to be in good agreement with calculated values.

    2003-11-01

    With the rise in obesity in America, the search for potential causes for this epidemic has begun to include a focus on environmental factors. Television (TV) viewing is one such factor, partially due to its potential as a stimulus for eating. The current study investigated the relationship between food intake and self-reported TV viewing in an effort to identify the impact of TV viewing on specific eating behaviors. Seventy-four overweight women seeking obesity treatment completed questionnaires assessing dietary habits and TV viewing behaviors. Results suggest that snacking, but not necessarily eating meals, while watching TV is associated with increased overall caloric intake and calories from fat. Therefore, interventions targeting stimulus control techniques to reduce snacking behavior may have an impact on overall caloric intake.

  14. Assuring safety without animal testing: Unilever's ongoing research programme to deliver novel ways to assure consumer safety.

    Assuring consumer safety without the generation of new animal data is currently a considerable challenge. However, through the application of new technologies and the further development of risk-based approaches for safety assessment, we remain confident it is ultimately achievable. For many complex, multi-organ consumer safety endpoints, the development, evaluation and application of new, non-animal approaches is hampered by a lack of biological understanding of the underlying mechanistic processes involved. The enormity of this scientific challenge should not be underestimated. To tackle this challenge a substantial research programme was initiated by Unilever in 2004 to critically evaluate the feasibility of a new conceptual approach based upon the following key components: 1.Developing new, exposure-driven risk assessment approaches. 2.Developing new biological (in vitro) and computer-based (in silico) predictive models. 3.Evaluating the applicability of new technologies for generating data (e.g. "omics", informatics) and for integrating new types of data (e.g. systems approaches) for risk-based safety assessment. Our research efforts are focussed in the priority areas of skin allergy, cancer and general toxicity (including inhaled toxicity). In all of these areas, a long-term investment is essential to increase the scientific understanding of the underlying biology and molecular mechanisms that we believe will ultimately form a sound basis for novel risk assessment approaches. Our research programme in these priority areas consists of in-house research as well as Unilever-sponsored academic research, involvement in EU-funded projects (e.g. Sens-it-iv, Carcinogenomics), participation in cross-industry collaborative research (e.g. Colipa, EPAA) and ongoing involvement with other scientific initiatives on non-animal approaches to risk assessment (e.g. UK NC3Rs, US "Human Toxicology Project" consortium).

  3. Collective Attitudes and the Anthropocentric View

    Directory of Open Access Journals (Sweden)

    Gallotti Mattia

    2016-03-01

    Full Text Available The anthropocentric view holds that the social world is a projection of mental states and attitudes onto the real world. However, there is more to a society of individuals than their psychological make up. In The Ant Trap, Epstein hints at the possibility that collective intentionality can, and should, be discarded as a pillar of social ontology. In this commentary I argue that this claim is motivated by an outdated view of the nature and structure of collective attitudes. If we aim at a good theory of social ontology, we need a good theory of collective intentionality.

    2003-01-01

    Organizations that rely on projects to implement their products must find effective mechanisms for propagating lessons learned on one project throughout the organization. A broad view of what constitutes a project's 'legacy' is presented that includes not just the design products and leftover parts, but new processes, relationships, technology, skills, planning data, and performance metrics. Based on research evaluating knowledge reuse in innovative contexts, this paper presents an approach to project legacy management that focuses on collecting and using legacy knowledge to promote organizational learning and effective reuse, while addressing factors of post-project responsibility, information obsolescence, and the importance of ancillary contextual information. .

    Schonlau, William J.

    2006-05-01

    An immersive viewing engine providing basic telepresence functionality for a variety of application types is presented. Augmented reality, teleoperation and virtual reality applications all benefit from the use of head mounted display devices that present imagery appropriate to the user's head orientation at full frame rates. Our primary application is the viewing of remote environments, as with a camera equipped teleoperated vehicle. The conventional approach where imagery from a narrow field camera onboard the vehicle is presented to the user on a small rectangular screen is contrasted with an immersive viewing system where a cylindrical or spherical format image is received from a panoramic camera on the vehicle, resampled in response to sensed user head orientation and presented via wide field eyewear display, approaching 180 degrees of horizontal field. Of primary interest is the user's enhanced ability to perceive and understand image content, even when image resolution parameters are poor, due to the innate visual integration and 3-D model generation capabilities of the human visual system. A mathematical model for tracking user head position and resampling the panoramic image to attain distortion free viewing of the region appropriate to the user's current head pose is presented and consideration is given to providing the user with stereo viewing generated from depth map information derived using stereo from motion algorithms.

  7. Loads and loads and loads: The influence of prospective load, retrospective load, and ongoing task load in prospective memory

    Directory of Open Access Journals (Sweden)

    Beat eMeier

    2015-06-01

    Full Text Available In prospective memory tasks different kinds of load can occur. Adding a prospective memory task can impose a load on ongoing task performance. Adding ongoing task load can affect prospective memory performance. The existence of multiple target events increases prospective load and adding complexity to the to-be-remembered action increases retrospective load. In two experiments, we systematically examined the effects of these different types of load on prospective memory performance. Results showed an effect of prospective load on costs in the ongoing task for categorical targets (Experiment 2, but not for specific targets (Experiment 1. Retrospective load and ongoing task load both affected remembering the retrospective component of the prospective memory task. We suggest that prospective load can enhance costs in the ongoing task due to additional monitoring requirements. Retrospective load and ongoing task load seem to impact the division of resources between the ongoing task and retrieval of the retrospective component, which may affect disengagement from the ongoing task. In general, the results demonstrate that the different types of load affect prospective memory differentially.

    Myrna C Bonaldo

    Full Text Available The current yellow fever outbreak in Brazil is the most severe one in the country in recent times. It has rapidly spread to areas where YF virus (YFV activity has not been observed for more than 70 years and vaccine coverage is almost null. Here, we sequenced the whole YFV genome of two naturally infected howler-monkeys (Alouatta clamitans obtained from the Municipality of Domingos Martins, state of Espírito Santo, Brazil. These two ongoing-outbreak genome sequences are identical. They clustered in the 1E sub-clade (South America genotype I along with the Brazilian and Venezuelan strains recently characterised from infections in humans and non-human primates that have been described in the last 20 years. However, we detected eight unique amino acid changes in the viral proteins, including the structural capsid protein (one change, and the components of the viral replicase complex, the NS3 (two changes and NS5 (five changes proteins, that could impact the capacity of viral infection in vertebrate and/or invertebrate hosts and spreading of the ongoing outbreak.

  11. Tipping Points and the Accommodation of the Abuser: Ongoing Incestuous Abuse during Adulthood

    Directory of Open Access Journals (Sweden)

    Warwick Middleton

    2015-07-01

    Full Text Available Until recently the widespread reality of ongoing incestuous abuse during adulthood had attracted no systematic research. The scientific literature was limited to the occasional case study and brief anecdotal references. This minimal literature was supplemented by biographical works written by or about victims of this form of abuse, and by press reports. With the advent of the Josef Fritzl case there was a very marked increase in the press reporting of such abuse, which in turn provided a reference point for more fine-grained data collection and scientific reporting. This paper introduces the subject of prolonged incest via the lens of organised abuse, summarises research on incestuous abuse and draws on multiple clinical examples to elucidate the mechanisms by which such abuse merges with, or develops into, variations of organised abuse, including that centred on the family, on prostitution, or on that involving abuse networks. The abuse practices, the net-working, and the ploys used to avoid prosecution practiced by the father perpetrating ongoing incestuous abuse during adulthood have much in common with other variants of organised sexual abuse.

  12. Continuous Traumatic Situations in the Face of Ongoing Political Violence: The Relationship Between CTS and PTSD.

    Nuttman-Shwartz, Orit; Shoval-Zuckerman, Yael

    2016-12-01

    This article presents a literature review of the concept of continuous traumatic situations (CTS), which relates to residents living in ongoing situations of political violence and national security threats. The first aim of this review is to narrow the gap regarding knowledge about the concept of CTS by presenting findings from studies that have assessed the effects of CTS on civilian populations. The second aim is to describe CTS in a way that highlights the differences and similarities between posttraumatic stress disorder and responses to CTS. This distinction is a necessary precondition for examining CTS, as is a careful clinical analysis of the development and course of symptoms. This literature review also highlights the importance of adopting a supplementary perspective for understanding the psychological impact of ongoing exposure to real threats, which can be used as a basis for developing intervention strategies that are appropriate for coping with life in the context of persistent violence. CTS can be manifested as emotions, behaviors, and perceptions among individuals, families, communities, and societies. The nature of the proposed model of CTS is a circular one, combining past and future perceptions and emotional reactions that have resulted from continuous and repeated traumatic experiences over an extended period of time. This wider understanding reflects the complexity of the CTS phenomenon. Various micro and macro interventions relating to CTS as the result of political violence situations and national security threats are presented, and recommendations for practice, policy, and future research are offered. © The Author(s) 2015.

  13. Equality in Healthcare: The Formation and Ongoing Legacy of an LGBT Advisory Council.

    Rosa, William; Fullerton, Chelsea; Keller, Ronald

    2015-12-01

    This article provides a broad overview of the literature on lesbian, gay, bisexual, transgender (LGBT) health disparities and workplace discrimination, as well as the context that led to the formation of an institutional LGBT Advisory Council. The Council was developed in order to demonstrate our ongoing commitment to LGBT inclusion and to improve the lived experiences for both LGBT patients and staff. A retrospective approach is utilized to explore the LGBT Advisory Council's journey to spearhead advocacy efforts at our institution. The Council's accomplishments include taking a leadership role in obtaining nationally recognized designations such as the Healthcare Equality Index and the Magnet Exemplar for Cultural Sensitivity, as well as adding sexual orientation, gender identity, and gender expression fields to our institution's electronic medical record system. Additionally, the Council guides and promotes ongoing house-wide cultural sensitivity staff training efforts. Most recently, the Council marched as a contingency in the world's largest Pride March for the first time in institutional history. It is our hope that our Council will become an inspiration and exemplar for similar groups to form at healthcare institutions and organizations across the nation. Allowing LGBT members of each individual healthcare community the agency to determine the direction of advocacy efforts is incredibly important; however, this must be coupled with an organizational commitment on behalf of leadership to follow through on these initiatives and to provide them with the resources they need in order to be successful.

    This cross-sectional study examined whether people who are exposed to mercury (Hg) vapours in ongoing artisanal gold mining activities have alteration in kidney function monitoring parameters. The study enrolled 164 miners and 127 participant controls. The Hg concentrations for miners and control participants were measured in blood (B-Hg; median 7.0 vs. 2.5 µg/L), urine (U-Hg; median 3.9 vs. 1.5 µg/g creatinine) and hair (H-Hg; median 0.8 vs. 0.4 µg/g hair). The biomarkers of renal function were creatinine, albumin and excretion of β-2 microglobulin. Glomerular filtration rate (eGFR) was calculated using the chronic kidney disease epidemiology collaboration equation. Significant statistical differences were found in Hg concentrations and eGFR levels between the two study groups ( p association was found between the prevalence of reduced eGFR (associated with Hg vapour exposure in ongoing artisanal gold mining, whose population has a level of Hg exposure from low to moderate (B-Hg from 3.4 to 11.0 µg/L and U-Hg from 1.3 to 9.6 µg/g creatinine).

  15. The diagnostic value of the 'skyline' view for radiographic examination of the equine navicular bone

    Zweers, A.D.; Dik, K.J.

    1988-01-01

    The radiographic diagnostic value of Rose's palmaroproximal-dorsodistal ('skyline') projection and Oxspring's dorsopalmar projection of the equine navicular bone were compared, by examining radiographs of 102 navicular bones originating from 66 randomly selected horses with clinical evidence of lameness located in the navicular area. In 27 navicular bones essential information was obtained from the skyline view, 15 independently of Oxspring's projection and 12 in addition to this view. For 11 navicular studies the D.P. projection was the most important diagnostic view. In the other 64 navicular bones information obtained from both views was of equal diagnostic value. Based on these results it is suggested that the skyline projection be utilized as an additional view, especially if there is a significant discrepancy between the clinical and radiographic findings based on lateromedial and Oxspring projections, and if ill-defined lesions of unknown significance are visible on the Oxspring projection [nl

    As independent experts, we have accompanied a series of major projects where plant control systems have been retrofitted with digital I and C technology. As General Expert Inspectors of our authority, we have investigated, inspected and certified such projects - from defining the tasks at hand trough planning, approving, implementing and commissioning down to the regular operation of the equipment. Our special focus has been on the proper adherence to the relevant safety issues in nuclear plants in accordance with the current state-of-the-art in science and technology, and to the applicable codes of practice. In September 2004, at the international 'Nuclear Plant Instrumentation, Control and Human Machine Interface Technology' meeting in Columbus/Ohio, we presented some major retrofit projects and reported about how we, as independent official experts, accompany and monitor the activities of retrofitting plants with advanced digital safety I and C equipment, from the safety point of view. With current report, we would like to provide more detailed information about the practical experience gained with digital safety I and C retrofits and the conclusions drawn for currently ongoing retrofit projects. We will look at both the technical and licensing aspects of implementing such projects

    2000-11-01

    Since the 2020 Vision project began in 1996, students from participating schools have completed and submitted a variety of scenarios describing potential world and regional conditions in the year 2020 and their possible effect on US national security. This report summarizes the students' views and describes trends observed over the course of the 2020 Vision project's five years. It also highlights the main organizational features of the project. An analysis of thematic trends among the scenarios showed interesting shifts in students' thinking, particularly in their views of computer technology, US relations with China, and globalization. In 1996, most students perceived computer technology as highly beneficial to society, but as the year 2000 approached, this technology was viewed with fear and suspicion, even personified as a malicious, uncontrollable being. Yet, after New Year's passed with little disruption, students generally again perceived computer technology as beneficial. Also in 1996, students tended to see US relations with China as potentially positive, with economic interaction proving favorable to both countries. By 2000, this view had transformed into a perception of China emerging as the US' main rival and ''enemy'' in the global geopolitical realm. Regarding globalization, students in the first two years of the project tended to perceive world events as dependent on US action. However, by the end of the project, they saw the US as having little control over world events and therefore, we Americans would need to cooperate and compromise with other nations in order to maintain our own well-being.

  7. Ectopic lymphoid structures support ongoing production of class-switched autoantibodies in rheumatoid synovium.

    Follicular structures resembling germinal centres (GCs) that are characterized by follicular dendritic cell (FDC) networks have long been recognized in chronically inflamed tissues in autoimmune diseases, including the synovium of rheumatoid arthritis (RA). However, it is debated whether these ectopic structures promote autoimmunity and chronic inflammation driving the production of pathogenic autoantibodies. Anti-citrullinated protein/peptide antibodies (ACPA) are highly specific markers of RA, predict a poor prognosis, and have been suggested to be pathogenic. Therefore, the main study objectives were to determine whether ectopic lymphoid structures in RA synovium: (i) express activation-induced cytidine deaminase (AID), the enzyme required for somatic hypermutation and class-switch recombination (CSR) of Ig genes; (ii) support ongoing CSR and ACPA production; and (iii) remain functional in a RA/severe combined immunodeficiency (SCID) chimera model devoid of new immune cell influx into the synovium. Using immunohistochemistry (IHC) and quantitative Taqman real-time PCR (QT-PCR) in synovial tissue from 55 patients with RA, we demonstrated that FDC+ structures invariably expressed AID with a distribution resembling secondary lymphoid organs. Further, AID+/CD21+ follicular structures were surrounded by ACPA+/CD138+ plasma cells, as demonstrated by immune reactivity to citrullinated fibrinogen. Moreover, we identified a novel subset of synovial AID+/CD20+ B cells outside GCs resembling interfollicular large B cells. In order to gain direct functional evidence that AID+ structures support CSR and in situ manufacturing of class-switched ACPA, 34 SCID mice were transplanted with RA synovium and humanely killed at 4 wk for harvesting of transplants and sera. Persistent expression of AID and Igamma-Cmu circular transcripts (identifying ongoing IgM-IgG class-switching) was observed in synovial grafts expressing FDCs/CD21L. Furthermore, synovial mRNA levels of AID were

  8. The making of a moral economy: women's views of monetary transactions in an 'egg sharing for research' scheme.

    2017-09-07

    There are growing debates about the appropriateness of offering money in exchange for the provision of bodily materials for clinical treatment and research. The bioethics literature and many practice guidelines have generally been opposed to such entanglement, depicting the use of money as contaminating, creating undue inducement, exploitation and commodification of the human body. However, two elements have been missing from these debates: (i) the perspectives of those people providing bodily materials when money is offered; and (ii) systematic empirical engagement with the notion of 'money' itself. This article seeks to fill those gaps in knowledge by providing detailed insights from a project investigating the views and experiences of women who volunteered to provide eggs for research in exchange for reduced fees for fertility treatment. Analysis of 29 semi-structured interviews reveals multiple ways in which volunteers reason through the involvement of 'money' in this domain and shows how their accounts diverge from pessimistic understandings of the role of monies in everyday life. When volunteers speak in detail about the monetary aspects of their participation they draw major, recurring, distinctions in five overlapping areas: their depiction of the monetized world of fertility treatment; their views of the different forms that money can take; a distancing of their actions from their understandings of how markets and commodities work; their location of the transactions within a particular clinic, and the ongoing importance of their eggs, post-transaction. This article: (i) responds to calls for concrete case studies to assist understandings of the inter-relationships of money and specific aspects of social life; (ii) adds to the sociology of money literature by providing empirical insights into how notions of money are deployed; (iii) presents much-needed perspectives from providers of bodily materials; and (iv) contributes to ongoing conversations between

    The topic of this book is known as dynamic scheduling, and is used to refer to three dimensions of project management and scheduling: the construction of a baseline schedule and the analysis of a project schedule's risk as preparation of the project control phase during project progress. This dynamic scheduling point of view implicitly assumes that the usability of a project's baseline schedule is rather limited and only acts as a point of reference in the project life cycle.

    Study of the atomic bomb survivors has provided uniquely valuable information about the types of effects that are produced by ionizing radiation and their relation to dose, age at exposure, time after irradiation, and other variables. There are still, however, many unresolved questions requiring further investigation. These include reassessment of the dosimetry in both Hiroshima and Nagasaki; continued follow-up of survivors for cancer and other late effects, especially those who were exposed early in life and are just now reaching the age when the common cancers of adult life make their appearance; further evaluation of the possibility of measuring genetic effects in the children of survivors; and continued longitudinal investigation of risk factors predisposing to cancer, preneoplastic lesions, and other diseases. To the extent that a strong statistical foundation is essential to such investigations, the high calibre and sophistication of ongoing statistical research at RERF augers well for the future. 30 references, 4 figures

  16. The Ongoing Rediscovery of Après-Coup as a Central Freudian Concept.

    Science.gov (United States)

    House, Jonathan

    2017-10-01

    Après-coup, Freud's Nachträglichkeit, is an essential psychoanalytic concept structuring each of four concepts, four mental processes that lie at the foundation of Freud's thinking: psychic trauma, repression, the creation of the unconscious, and the creation of infantile sexuality. It is argued here that infantile sexual drives, in contrast to the self-preservative instincts, arise from a two-step process of translation and repression in which the residues of failed translation become source-objects of the drives. These residues of failed translation have an associative resonance with adult sexuality, and the child is driven to ongoing attempts to translate them, to make them meaningful après coup. Thus, après-coup is at the heart of the human subject as a sexual creature who requires, desires, and creates meaning.

    2013-11-01

    Full Text Available This research describes the predicted outcomes of a Kenyan Cloud School (KCS, which is a MOOC that contains all courses taught at the secondary school level in Kenya. This MOOC will consist of online, ongoing subjects in both English and Kiswahili. The KCS subjects offer self-testing and peer assessment to maximize scalability, and digital badges to show progress and completion to recognize and validate non-formal learning. The KCS uses the Moodle LMS with responsive web design to increase ubiquitous access from any device. Access is free and open, and the KCS intends to be a contextualized open educational resource for formal secondary institutions to support blended learning and a free source of non-formal education for lifelong learning. The expected outcomes are that this effort will reduce secondary school dropout rates, improve test scores, become a quality resource for blended learning, as well as validate and recognize lifelong learning in Kenya.

    The ongoing high precision E821 Brookhaven National Laboratory experiment on muon g-2 is promising to probe a theory involving supersymmetry. We have studied the constraints on minimal Anomaly Mediated Supersymmetry Breaking (AMSB) model using the current data of muon g-2 from Brookhaven. A scenario of seeing no deviation from the Standard Model is also considered, within $2\\sigma$ limit of the combined error from the Standard Model result and the Brookhaven predicted uncertainty level. The resulting constraint is found to be complementary to what one obtains from $b \\to s+ \\gamma$ bounds within the AMSB scenario, since only a definite sign of $\\mu$ is effectively probed via $b \\to s+ \\gamma$. A few relevant generic features of the model are also described for disallowed regions of the parameter space.

    Group medical visits (GMVs), which combine 1-on-1 clinical consultations and group self-management education, have emerged as a promising vehicle for supporting type 2 diabetes management in primary care. However, few evaluations exist of ongoing diabetes GMVs embedded in medical practices. This study used a quasi-experimental design to evaluate diabetes GMV at a large family medicine practice. We examined program attendance and attrition, used propensity score matching to create a matched comparison group, and compared participants and the matched group on clinical, process of care, and utilization outcomes. GMV participants (n = 230) attended an average of 1 session. Participants did not differ significantly from the matched comparison group (n = 230) on clinical, process of care or utilization outcomes. The diabetes GMV was not associated with improvements in outcomes. Further studies should examine diabetes GMV implementation challenges to enhance their effectiveness in everyday practice. © Copyright 2018 by the American Board of Family Medicine.

  1. Missed opportunities: poor linkage into ongoing care for HIV-positive pregnant women in Mwanza, Tanzania.

    Directory of Open Access Journals (Sweden)

    Deborah Watson-Jones

    Full Text Available Global coverage of prevention of mother-to-child (PMTCT services reached 53% in 2009. However the number of pregnant women who test positive for HIV in antenatal clinics and who link into long-term HIV care is not known in many resource-poor countries. We measured the proportion of HIV-positive pregnant women in Mwanza city, Tanzania, who completed the cascade of care from antenatal HIV diagnosis to assessment and engagement in care in adult HIV clinics.Thirty antenatal and maternity ward health workers were interviewed about PMTCT activities. Nine antenatal HIV education sessions were observed. A prospective cohort of 403 HIV-positive women was enrolled by specially-trained clinicians and nurses on admission to delivery and followed for four months post-partum. Information was collected on referral and attendance at adult HIV clinics, eligibility for highly active antiretroviral therapy (HAART and reasons for lack of attendance.Overall, 70% of PMTCT health workers referred HIV-positive pregnant women to the HIV clinic for assessment and care. Antenatal HIV education sessions did not cover on-going care for HIV-infected women. Of 310 cohort participants tested in pregnancy, 51% had received an HIV clinic referral pre-delivery. Only 32% of 244 women followed to four months post-partum had attended an HIV clinic and been assessed for HAART eligibility. Non-attendance for HIV care was independently associated with fewer antenatal visits, poor PMTCT prophylaxis compliance, non-disclosure of HIV status, and non-Sukuma ethnicity.Most women identified as HIV-positive during pregnancy were not assessed for HAART eligibility during pregnancy or in the first four months post-partum. Initiating HAART at the antenatal clinic, improved counselling and linkages to care between PMTCT and adult HIV treatment services and reducing stigma surrounding disclosure of HIV results would benefit on-going care of HIV-positive pregnant women.

  2. Persistent Borrelia Infection in Patients with Ongoing Symptoms of Lyme Disease

    Marianne J. Middelveen

    2018-04-01

    Full Text Available Introduction: Lyme disease is a tickborne illness that generates controversy among medical providers and researchers. One of the key topics of debate is the existence of persistent infection with the Lyme spirochete, Borrelia burgdorferi, in patients who have been treated with recommended doses of antibiotics yet remain symptomatic. Persistent spirochetal infection despite antibiotic therapy has recently been demonstrated in non-human primates. We present evidence of persistent Borrelia infection despite antibiotic therapy in patients with ongoing Lyme disease symptoms. Methods: In this pilot study, culture of body fluids and tissues was performed in a randomly selected group of 12 patients with persistent Lyme disease symptoms who had been treated or who were being treated with antibiotics. Cultures were also performed on a group of ten control subjects without Lyme disease. The cultures were subjected to corroborative microscopic, histopathological and molecular testing for Borrelia organisms in four independent laboratories in a blinded manner. Results: Motile spirochetes identified histopathologically as Borrelia were detected in culture specimens, and these spirochetes were genetically identified as Borrelia burgdorferi by three distinct polymerase chain reaction (PCR-based approaches. Spirochetes identified as Borrelia burgdorferi were cultured from the blood of seven subjects, from the genital secretions of ten subjects, and from a skin lesion of one subject. Cultures from control subjects without Lyme disease were negative for Borrelia using these methods. Conclusions: Using multiple corroborative detection methods, we showed that patients with persistent Lyme disease symptoms may have ongoing spirochetal infection despite antibiotic treatment, similar to findings in non-human primates. The optimal treatment for persistent Borrelia infection remains to be determined.

  3. Extraction and characterization of essential discharge patterns from multisite recordings of spiking ongoing activity.

    Directory of Open Access Journals (Sweden)

    Riccardo Storchi

    Full Text Available Neural activation patterns proceed often by schemes or motifs distributed across the involved cortical networks. As neurons are correlated, the estimate of all possible dependencies quickly goes out of control. The complex nesting of different oscillation frequencies and their high non-stationariety further hamper any quantitative evaluation of spiking network activities. The problem is exacerbated by the intrinsic variability of neural patterns.Our technique introduces two important novelties and enables to insulate essential patterns on larger sets of spiking neurons and brain activity regimes. First, the sampling procedure over N units is based on a fixed spike number k in order to detect N-dimensional arrays (k-sequences, whose sum over all dimension is k. Then k-sequences variability is greatly reduced by a hierarchical separative clustering, that assigns large amounts of distinct k-sequences to few classes. Iterative separations are stopped when the dimension of each cluster comes to be smaller than a certain threshold. As threshold tuning critically impacts on the number of classes extracted, we developed an effective cost criterion to select the shortest possible description of our dataset. Finally we described three indexes (C,S,R to evaluate the average pattern complexity, the structure of essential classes and their stability in time.We validated this algorithm with four kinds of surrogated activity, ranging from random to very regular patterned. Then we characterized a selection of ongoing activity recordings. By the S index we identified unstable, moderatly and strongly stable patterns while by the C and the R indices we evidenced their non-random structure. Our algorithm seems able to extract interesting and non-trivial spatial dynamics from multisource neuronal recordings of ongoing and potentially stimulated activity. Combined with time-frequency analysis of LFPs could provide a powerful multiscale approach linking population

  4. Ongoing movement of the hermit warbler X Townsend's warbler hybrid zone.

    Directory of Open Access Journals (Sweden)

    Meade Krosby

    Full Text Available BACKGROUND: Movements of hybrid zones - areas of overlap and interbreeding between species - are difficult to document empirically. This is true because moving hybrid zones are expected to be rare, and because movement may proceed too slowly to be measured directly. Townsend's warblers (Dendroica townsendi hybridize with hermit warblers (D. occidentalis where their ranges overlap in Washington and Oregon. Previous morphological, behavioral, and genetic studies of this hybrid zone suggest that it has been steadily moving into the geographical range of hermit warblers, with the more aggressive Townsend's warblers replacing hermit warblers along ∼2000 km of the Pacific coast of Canada and Alaska. Ongoing movement of the zone, however, has yet to be empirically demonstrated. METHODOLOGY/PRINCIPAL FINDINGS: We compared recently sampled hybrid zone specimens to those collected 10-20 years earlier, to test directly the long-standing hypothesis of hybrid zone movement between these species. Newly sampled specimens were more Townsend's-like than historical specimens, consistent with ongoing movement of the zone into the geographical range of hermit warblers. CONCLUSIONS/SIGNIFICANCE: While movement of a hybrid zone may be explained by several possible mechanisms, in this case a wealth of existing evidence suggests that movement is being driven by the competitive displacement of hermit warblers by Townsend's warblers. That no ecological differences have been found between these species, and that replacement of hermit warblers by Townsend's warblers is proceeding downward in latitude and elevation - opposite the directions of range shifts predicted by recent climate change - further support that this movement is not being driven by alternative environmental factors. If the mechanism of competitive displacement is correct, whether this process will ultimately lead to the extinction of hermit warblers will depend on the continued maintenance of the

    Iodine-123-metaiodobenzylguanidine ( 123 I-MIBG) has been used to assess the integrity and function of the cardiac sympathetic nervous system in patients with heart failure. Heart-type fatty acid binding protein (H-FABP) is released into the circulation when the myocardium is injured, and H-FABP has been recently used as a novel marker for the diagnosis of ongoing myocardial damage. The aim of the present study was to compare cardiac sympathetic nervous activity assessed by 123 I-MIBG imaging with serum levels of H-FABP in patients with heart failure. Fifty patients with chronic heart failure were studied. 123 I-MIBG imaging was carried out at 30 min (early) and 240 min (delayed) after the tracer injection. We measured serum levels of H-FABP using a sandwich enzyme linked immunosorbent assay. Heart to mediastinum (H/M) ratios of 123 I-MIBG decreased and washout rate increased with higher New York Heart Association (NYHA) functional class. H-FABP, norepinephrine and brain natriuretic peptide (BNP) levels increased as the severity of NYHA class advanced. Delayed H/M ratio was significantly correlated with H-FABP (r=-0.296, p=0.029) and BNP (r=-0.335, p=0.0213). Myocardial washout rate of 123 I-MIBG was also correlated with H-FABP (r=0.469, p 123 I-MIBG imaging is an appropriate approach to evaluate non-invasively not only cardiac sympathetic nervous activity, but also latent ongoing myocardial damage in the failing heart.

    Lyme disease is a tickborne illness that generates controversy among medical providers and researchers. One of the key topics of debate is the existence of persistent infection with the Lyme spirochete, Borrelia burgdorferi , in patients who have been treated with recommended doses of antibiotics yet remain symptomatic. Persistent spirochetal infection despite antibiotic therapy has recently been demonstrated in non-human primates. We present evidence of persistent Borrelia infection despite antibiotic therapy in patients with ongoing Lyme disease symptoms. In this pilot study, culture of body fluids and tissues was performed in a randomly selected group of 12 patients with persistent Lyme disease symptoms who had been treated or who were being treated with antibiotics. Cultures were also performed on a group of ten control subjects without Lyme disease. The cultures were subjected to corroborative microscopic, histopathological and molecular testing for Borrelia organisms in four independent laboratories in a blinded manner. Motile spirochetes identified histopathologically as Borrelia were detected in culture specimens, and these spirochetes were genetically identified as Borrelia burgdorferi by three distinct polymerase chain reaction (PCR)-based approaches. Spirochetes identified as Borrelia burgdorferi were cultured from the blood of seven subjects, from the genital secretions of ten subjects, and from a skin lesion of one subject. Cultures from control subjects without Lyme disease were negative for Borrelia using these methods. Using multiple corroborative detection methods, we showed that patients with persistent Lyme disease symptoms may have ongoing spirochetal infection despite antibiotic treatment, similar to findings in non-human primates. The optimal treatment for persistent Borrelia infection remains to be determined.

    On June 4, 2011, at 18:45 UTC, Cordón Caulle volcano (Southern Andes, 40.52S, 72.14W) erupted explosively after 51 years of quiescence. The last eruption occurred in 1960 and was triggered by the great Mw 9.5 Chile earthquake. The ongoing eruption started after 2 months of increased shallow seismicity as recorded by OVDAS (the volcano observatory at Sernageomin). This close monitoring effort allowed a timely eruption forecast with at least 3 hours of warning, which facilitated the crisis response. In addition to this successful performance, for the first time in Chile volcanic hazards were assessed in advance supporting the emergency management. In particular, tephra dispersal was daily forecasted using the ASHFALL advection-diffusion model and potential lahars and PDC impact zones were delineated according to numerical approaches. The first eruptive stage lasted 27 hours. It was characterized by ca. 15-km strong Plinian-like column, associated with the emission of 0.2 - 0.4 km3 of magma (DRE). Tephra fallout mostly occurred in Chile and Argentina, although fine particles and aerosols circumnavigated the globe twice, causing disruptions on air navigation across the Southern Hemisphere. The second ongoing eruptive stage has been characterized by persistent weak plumes and lava emission at effusion rates in the range of 20 and 60 m3/s, which total volume is estimated case of successful eruption forecast and hazards assessment but it is also an important case-study of silicic eruptions in an arc segment where mostly mafic magmas have been erupted during the Holocene.

    In its simplest form, X ray imaging is the collection of attenuation shadows that are projected from an ideal X ray point source on to an image receptor. This simple form is true for all X ray imaging modalities, including complex ones that involve source and receptor movement, such as computed tomography (CT). This simplified view, however, is made vastly more complex by the non-ideal point source, by the consequences of projecting a 3-D object on to a 2-D detector and by the presence of scattered radiation, generated within the patient, which will degrade any image that is captured.

    To respond to national needs for improved productivity in engineering design and manufacturing, a NASA supported joint industry/government project is underway denoted Integrated Programs for Aerospace-Vehicle Design (IPAD). The objective is to improve engineering productivity through better use of computer technology. It focuses on development of technology and associated software for integrated company-wide management of engineering information. The project has been underway since 1976 under the guidance of an Industry Technical Advisory Board (ITAB) composed of representatives of major engineering and computer companies and in close collaboration with the Air Force Integrated Computer-Aided Manufacturing (ICAM) program. Results to date on the IPAD project include an in-depth documentation of a representative design process for a large engineering project, the definition and design of computer-aided design software needed to support that process, and the release of prototype software to integrate selected design functions. Ongoing work concentrates on development of prototype software to manage engineering information, and initial software is nearing release.

    Nowinski, Jessica Lang; Dismukes, Key R.

    2005-01-01

    Two experiments examined whether prospective memory performance is influenced by contextual cues. In our automatic activation model, any information available at encoding and retrieval should aid recall of the prospective task. The first experiment demonstrated an effect of the ongoing task context; performance was better when information about the ongoing task present at retrieval was available at encoding. Performance was also improved by a strong association between the prospective memory target as it was presented at retrieval and the intention as it was encoded. Experiment 2 demonstrated boundary conditions of the ongoing task context effect, which implicate the association between the ongoing and prospective tasks formed at encoding as the source of the context effect. The results of this study are consistent with predictions based on automatic activation of intentions.

  2. Loads and loads and loads: the influence of prospective load, retrospective load, and ongoing task load in prospective memory

    Science.gov (United States)

    Meier, Beat; Zimmermann, Thomas D.

    2015-01-01

    In prospective memory tasks different kinds of load can occur. Adding a prospective memory task can impose a load on ongoing task performance. Adding ongoing task load (OTL) can affect prospective memory performance. The existence of multiple target events increases prospective load (PL) and adding complexity to the to-be-remembered action increases retrospective load (RL). In two experiments, we systematically examined the effects of these different types of load on prospective memory performance. Results showed an effect of PL on costs in the ongoing task for categorical targets (Experiment 2), but not for specific targets (Experiment 1). RL and OTL both affected remembering the retrospective component of the prospective memory task. We suggest that PL can enhance costs in the ongoing task due to additional monitoring requirements. RL and OTL seem to impact the division of resources between the ongoing task and retrieval of the retrospective component, which may affect disengagement from the ongoing task. In general, the results demonstrate that the different types of load affect prospective memory differentially. PMID:26082709

    Full Text Available Follicular structures resembling germinal centres (GCs that are characterized by follicular dendritic cell (FDC networks have long been recognized in chronically inflamed tissues in autoimmune diseases, including the synovium of rheumatoid arthritis (RA. However, it is debated whether these ectopic structures promote autoimmunity and chronic inflammation driving the production of pathogenic autoantibodies. Anti-citrullinated protein/peptide antibodies (ACPA are highly specific markers of RA, predict a poor prognosis, and have been suggested to be pathogenic. Therefore, the main study objectives were to determine whether ectopic lymphoid structures in RA synovium: (i express activation-induced cytidine deaminase (AID, the enzyme required for somatic hypermutation and class-switch recombination (CSR of Ig genes; (ii support ongoing CSR and ACPA production; and (iii remain functional in a RA/severe combined immunodeficiency (SCID chimera model devoid of new immune cell influx into the synovium.Using immunohistochemistry (IHC and quantitative Taqman real-time PCR (QT-PCR in synovial tissue from 55 patients with RA, we demonstrated that FDC+ structures invariably expressed AID with a distribution resembling secondary lymphoid organs. Further, AID+/CD21+ follicular structures were surrounded by ACPA+/CD138+ plasma cells, as demonstrated by immune reactivity to citrullinated fibrinogen. Moreover, we identified a novel subset of synovial AID+/CD20+ B cells outside GCs resembling interfollicular large B cells. In order to gain direct functional evidence that AID+ structures support CSR and in situ manufacturing of class-switched ACPA, 34 SCID mice were transplanted with RA synovium and humanely killed at 4 wk for harvesting of transplants and sera. Persistent expression of AID and Igamma-Cmu circular transcripts (identifying ongoing IgM-IgG class-switching was observed in synovial grafts expressing FDCs/CD21L. Furthermore, synovial mRNA levels of AID

    America's abundant unconventional oil and natural gas (UOG) resources are critical components of our nation's energy portfolio. These resources need to be prudently developed to derive maximum benefits. In spite of the long history of hydraulic fracturing, the optimal number of fracturing stages during multi-stage fracture stimulation in horizontal wells is not known. In addition, there is the dire need of a comprehensive understanding of ways to improve the recovery of shale gas with little or no impacts on the environment. Research that seeks to expand our view of effective and environmentally sustainable ways to develop our nation's oil and natural gas resources can be done in the laboratory or at a computer; but, some experiments must be performed in a field setting. The Department of Energy (DOE) Field Lab Observatory projects are designed to address those research questions that must be studied in the field. The Department of Energy (DOE) is developing a suite of "field laboratory" test sites to carry out collaborative research that will help find ways of improving the recovery of energy resources as much as possible, with as little environmental impact as possible, from "unconventional" formations, such as shale and other low permeability rock formations. Currently there are three field laboratories in various stages of development and operation. Work is on-going at two of the sites: The Hydraulic Fracturing Test Site (HFTS) in the Permian Basin and the Marcellus Shale Energy and Environmental Lab (MSEEL) project in the Marcellus Shale Play. Agreement on the third site, the Utica Shale Energy and Environmental Lab (USEEL) project in the Utica Shale Play, was just recently finalized. Other field site opportunities may be forthcoming. This presentation will give an overview of the three field laboratory projects.

    The main goal of the chapter is the presentation of the application project portfolio management approach to support development of e-Municipality and public administration information systems. The models of how people publish and utilize information on the web have been transformed continually. Instead of simply viewing on static web pages, users publish their own content through blogs and photo- and video-sharing slides. Analysed in this chapter, ICT (Information Communication Technology) projects for municipalities cover the mixture of the static web pages, e-Government information systems, and Wikis. So, for the management of the ICT projects' mixtures the portfolio project management approach is proposed.

    Full Text Available Abstract Background Many countries have developed, or are developing, national strategies aimed at reducing the harms associated with hepatitis C infection. Making these strategies relevant to the vast majority of those affected by hepatitis C requires a more complete understanding of the short and longer term impacts of infection. We used a systematic approach to scope the literature to determine what is currently known about the health and psychosocial impacts of hepatitis C along the trajectory from exposure to ongoing chronic infection, and to identify what knowledge gaps remain. Methods PubMed, Current Contents and PsychINFO databases were searched for primary studies published in the ten years from 2000–2009 inclusive. Two searches were conducted for studies on hepatitis C in adult persons focusing on: outcomes over time (primarily cohort and other prospective designs; and the personal and psychosocial impacts of chronic infection. All retrieved studies were assessed for eligibility according to specific inclusion/exclusion criteria, data completeness and methodological coherence. Outcomes reported in 264 included studies were summarized, tabulated and synthesized. Results Injecting drug use (IDU was a major risk for transmission with seroconversion occurring relatively early in injecting careers. Persistent hepatitis C viraemia, increasing age and excessive alcohol consumption independently predicted disease progression. While interferon based therapies reduced quality of life during treatment, improvements on baseline quality of life was achieved post treatment – particularly when sustained viral response was achieved. Much of the negative social impact of chronic infection was due to the association of infection with IDU and inflated assessments of transmission risks. Perceived discrimination was commonly reported in health care settings, potentially impeding health care access. Perceptions of stigma and experiences of

  10. Ongoing compound field potentials from octopus brain are labile and vertebrate-like.

    Ongoing electrical activity was recorded from the brain of the virtually intact, semirestrained, unanesthetized octopus by semimicroelectrodes thrust through the cartilage into the optic, vertical or basal lobe. With flexible lead-in wires such electrodes were carried by and moved with the head without causing movement artifacts. Controls suggest that the activity reported comes from the brain; it is reversibly flattened by doses of urethane that do not embarrass respiration. Muscle potentials are only troublesome on occasion. Seen through a wideband filter, neuronal spikes are usually small or below noise level under these conditions; slow waves (1-70 Hz) dominate, with a maximum less than 25 Hz, usually less than 10 Hz and no consistent sharp peaks. The fall in power above ca. 25 Hz is usually slower than in the typical vertebrate EEG but the average power spectrum is much more like those of vertebrate brains than of cerebral ganglia of other invertebrates (insect, crustacean, gastropod). Variance among sample epochs is large, e.g. short spells may have relatively much more low frequency (less than 25 Hz) or more 'hashy' high frequency (greater than 50 Hz) energy; there may be runs of spikes. Fluctuation in the composition of ongoing activity is graphically shown by writing out in parallel the outputs of several narrow band (one octave) filters; this shows irregular low frequency waxing and waning of the amplitude in each band. The envelopes were computed and their peak power is around 1 Hz or lower; the waxing and waning in the several bands is sometimes strongly correlated, especially when the envelope amplitude is large and slow. Optic lobe activity tends usually to be faster, with more small spikey hash than in the vertical lobe. The described electrical activity of the brain is strikingly episodic; it is recorded during seconds or minutes separated by long intervals of nearly electrical silence (10-40 dB lower power; the difference larger at frequencies

  12. On-going collaborative priority-setting for research activity: a method of capacity building to reduce the research-practice translational gap.

    Science.gov (United States)

    Cooke, Jo; Ariss, Steven; Smith, Christine; Read, Jennifer

    2015-05-07

    International policy suggests that collaborative priority setting (CPS) between researchers and end users of research should shape the research agenda, and can increase capacity to address the research-practice translational gap. There is limited research evidence to guide how this should be done to meet the needs of dynamic healthcare systems. One-off priority setting events and time-lag between decision and action prove problematic. This study illustrates the use of CPS in a UK research collaboration called Collaboration and Leadership in Applied Health Research and Care (CLAHRC). Data were collected from a north of England CLAHRC through semi-structured interviews with 28 interviewees and a workshop of key stakeholders (n = 21) including academics, NHS clinicians, and managers. Documentary analysis of internal reports and CLAHRC annual reports for the first two and half years was also undertaken. These data were thematically coded. Methods of CPS linked to the developmental phase of the CLAHRC. Early methods included pre-existing historical partnerships with on-going dialogue. Later, new platforms for on-going discussions were formed. Consensus techniques with staged project development were also used. All methods demonstrated actual or potential change in practice and services. Impact was enabled through the flexibility of research and implementation work streams; 'matched' funding arrangements to support alignment of priorities in partner organisations; the size of the collaboration offering a resource to meet project needs; and the length of the programme providing stability and long term relationships. Difficulties included tensions between being responsive to priorities and the possibility of 'drift' within project work, between academics and practice, and between service providers and commissioners in the health services. Providing protected 'matched' time proved difficult for some NHS managers, which put increasing work pressure on them. CPS is more time

    that the best practice knowledge has not permeated sufficiently to the practice. Furthermore, the appropriate application of information and communication technology (ICT) remains a big challenge, and finally project managers are not sufficiently trained in organizing and conducting virtual projects....... The overall implications for research and practice are to acknowledge virtual project management as very different to traditional project management and to address this difference.......Virtual projects are common with global competition, market development, and not least the financial crisis forcing organizations to reduce their costs drastically. Organizations therefore have to place high importance on ways to carry out virtual projects and consider appropriate practices...

  15. Project Management Yinyang: Coupling project success and client satisfaction

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available Our research applies paradox theory to a project management construct to help project management researchers and practitioners understand the tensions that can exist between project success and client satisfaction. Our research highlights that although project success and client satisfaction are both present within a project management construct, they also belong to different functional systems. Project success and client satisfaction have different systemic-discourses and use different language games to convey information. These distinctions can create latent and sometimes salient tensions within the project management construct that project managers must understand, embrace, and work with. We have used a Grounded Theory (GT methodology to explore the lived experience of project managers, and from this have identified a phenomenon which we have termed project management yinyang. Project management yinyang is the state that exists when both project success and Client satisfaction are tightly coupled within the project management construct. Project management yinyang highlights that these two phenomena cannot be viewed as separate elements because the ‘seed’ of each exists within the other. And to truly achieve one, you must also achieve the other. Our findings indicate that in order to create project management yinyang the project manager must embrace a paradoxical yet holistic philosophy. They must understand the complementarity, interdependency, and structural coupling that exists between the positivist and interpretivist paradigms within the project management construct. They must understand how satisfaction (Yin and success (Yang are created through focus. Furthermore, they must understand how project management yinyang is separate from, but borne from, the convergence of the other two elements.

  4. The CAREM-25 project from the risk point of view

    International Nuclear Information System (INIS)

    Baron, J.H.

    1998-01-01

    The future use of the nuclear energy for electricity production is considered a possible alternative, mainly taking into account the high environmental impact of the fossil fuel alternatives (greenhouse effect, acid rain). In a worldwide context, however, it is desirable for the new nuclear power plants to be safer than the present ones. To demonstrate the safety level of a nuclear installation, the Risk Analysis (in fact, Probabilistic Safety Analysis) is an adequate tool, as it allows for the risk level quantification. The risk itself is composed of two factors, the first takes into account the probability associated with accidental sequences that release radioactive materials, the second takes into account the amount and consequences of such a release. In the present work, the reduction of both factors is faced, the probability by using simpler safety systems (inherently safe systems), and the consequence by using small power production units, that have, besides, passive mitigation systems and long response times. The work is illustrated with a risk comparison for electricity production via CAREM-25 units, against via a classic design unit (Atucha II). The results are base in Probabilistic Safety Studies performed for both installations. The conclusions show an effective risk reduction (both in probability and in consequence), reaching the point where in no case acute irradiation effects are predicted in the vicinity of the accidented plant.

    Research has established the mental health sequelae following disaster, with studies now focused on understanding factors that mediate these outcomes. This study focused on anger, alcohol, subsequent life stressors and traumatic events as mediators in the development of mental health disorders following the 2009 Black Saturday Bushfires, Australia's worst natural disaster in over 100 years. This study examined data from 1017 (M = 404, F = 613) adult residents across 25 communities differentially affected by the fires and participating in the Beyond Bushfires research study. Data included measures of fire exposure, posttraumatic stress disorder, depression, alcohol abuse, anger and subsequent major life stressors and traumatic events. Structural equation modeling assessed the influence of factors mediating the effects of fire exposure on mental health outcomes. Three mediation models were tested. The final model recorded excellent fit and observed a direct relationship between disaster exposure and mental health outcomes (b = .192, p disaster exposure and development of mental health problems. The findings have significant implications for the assessment of anger post disaster, the provision of targeted anger-focused interventions and delivery of government and community assistance and support in addressing ongoing stressors in the post-disaster context to minimize subsequent mental health consequences. © The Royal Australian and New Zealand College of Psychiatrists 2015.

  14. Ongoing transmission of hepatitis B virus in rural parts of the Netherlands, 2009-2013.

    Directory of Open Access Journals (Sweden)

    Loes C Soetens

    Full Text Available Reported acute hepatitis B incidence in the Netherlands reached its nadir in 2013. However, regional signals about increased number of hepatitis B cases raised the question how hepatitis B incidence was distributed over the country. In this study, regional differences in hepatitis B epidemiology were investigated using epidemiological and molecular data.Acute hepatitis B virus (HBV infections, reported between 2009-2013, were included. If serum was available, a fragment of S and C gene of the HBV was amplified and sequenced. Regional differences in incidence were studied by geographical mapping of cases and cluster analysis. Regional differences in transmission were studied by constructing regional maximum parsimony trees based on the C gene to assess genetic clustering of cases.Between 2009 and 2013, 881 cases were notified, of which respectively 431 and 400 cases had serum available for S and C gene sequencing. Geographical mapping of notified cases revealed that incidences in rural border areas of the Netherlands were highest. Cluster analysis identified two significant clusters (p<0.000 in the South-western and North-eastern regions. Genetic cluster analysis showed that rural border areas had relatively large clusters of cases with indistinguishable sequences, while other regions showed more single introductions.This study showed that regional differences in HBV epidemiology were present in the Netherlands. Rural border regions showed higher incidences and more ongoing transmission, mainly among MSM, than the more urban inland areas. Therefore, preventive measures should be enhanced in these regions.

  15. Transitional Justice in Ongoing Conflicts and Post-War Reconstruction: Reintegrating Donbas into Ukraine

    Directory of Open Access Journals (Sweden)

    Tomasz Lachowski

    2017-12-01

    Full Text Available The main aim of the paper is to analyse the potential transitional justice mechanisms, directed at reintegration of Donbas, a territory temporarily occupied by pro-Russian separatists, being under the combination of a direct and indirect control of Kremlin, with Ukraine. In the aftermath of the Revolution of Dignity and a remove of ex-President Viktor Yanukovych as a consequence of Euromaidan protests held in Kyiv, in the Winter 2013/14, Ukraine became a state involved in the international armed conflict covering its Eastern provinces as a result of an external aggression of the Russian Federation. Furthermore, since early-2014, Moscow is continuously using pro-Russian militants to form and uphold unrecognised, de facto regimes of the so-called ‘Donetsk’ and ‘Luhansk People’s Republic(s’ affecting the territorial integrity of the Ukrainian state. It is argued that Kyiv shall take into consideration some of the peace and restoration models applied in similar conflict or post-conflict environments, such as the United Nations Transitional Administration for Eastern Slavonia, Baranja and Western Sirmium (UNTAES or the experience of numerous disarmament, demobilisation and reintegration (DDR programs, filled with the transitional justice component. Moreover, by emphasising the context of a military (semifrozen conflict in Eastern Ukraine, the paper is going to shed more light on the possible application of transitional justice tool-kit in the ongoing conflicts scenarios and its potential contribution to the shift from a conflict to the postwar environment.

    Prospective memory (PM) is the process associated with the task of realizing delayed intentions in the future. Researchers distinguish two types of PM, namely time-based PM (tbPM) and event-based PM (ebPM). Experiment 1 investigated the developmental trajectory of 3- to 5-year-old preschool children's PM ability, and the occurrence of delayed retrieval (children execute the PM task in a larger window of opportunity) in both tbPM and ebPM tasks. Results revealed that the 5-year-old children outperformed the 3- and 4-year-old children in PM. Moreover, delayed retrieval was more likely to occur in tbPM task than in ebPM task. In Experiment 2, the influence of ongoing task (OT) difficulty on PM performance was investigated with a sample of 5-year-old children. Results revealed no significant effect of OT difficulty on PM performance. In Experiment 3, we improved children's motivation level to complete the OT, then explored the influence of OT difficulty on children's PM performance. Results revealed that the effect of OT difficulty on PM performance became significant after increasing the children's motivation to complete the OT. These results provide insights into the mechanism of attentional resource allocation in PM tasks and have crucial educational and social implications.

    ''Ischaemic memory'' is defined as a prolonged functional and/or biochemical alteration remaining after a particular episode of severe myocardial ischaemia. The biochemical alteration has been reported as metabolic stunning. Metabolic imaging has been used to detect the footprint left by previous ischaemic episodes evident due to delayed recovery of myocardial metabolism (persistent dominant glucose utilization with suppression of fatty acid oxidation). β-Methyl-p-[{sup 123}I]iodophenylpentadecanoic acid (BMIPP) is a single-photon emission computed tomography (SPECT) radiotracer widely used for metabolic imaging in clinical settings in Japan. In patients with suspected coronary artery disease but no previous myocardial infarction, BMIPP has shown acceptable diagnostic accuracy. In particular, BMIPP plays an important role in the identification of prior ischaemic insult in patients arriving at emergency departments with acute chest pain syndrome. Recent data also show the usefulness of {sup 123}I-BMIPP SPECT for predicting cardiovascular events in patients undergoing haemodialysis. Similarly, SPECT or PET imaging with {sup 18}F-FDG injected during peak exercise or after exercise under fasting conditions shows an increase in FDG uptake in postischaemic areas. This article will overview the roles of ischaemic memory imaging both under established indications and in ongoing investigations. (orig.)

    Data obtained at visible and near-infrared wavelengths by OMEGA on MarsExpress and CRISM on MRO provide definitive evidence for the presence of phyllosilicates and other hydrated phases on Mars. A diverse range of both Fe/Mg-OH and Al-OH-bearing phyllosilicates were identified including the smectites, nontronite, saponite, and montmorillonite. In order to constrain the abundances of these phyllosilicates spectral analyses of mixtures are needed. We report on our on-going effort to enable the quantitative evaluation of the abundance of hydrated-hydroxylated silicates when they are contained in mixtures. We include two component mixtures of hydrated/hydroxylated silicates with each other and with two analogs for other martian materials; pyroxene (enstatite) and palagonitic soil (an alteration product of basaltic glass). For the hydrated-hydroxylated silicates we include saponite and montmorillonite (Mg- and Al- rich smectites). We prepared three size separates of each end-member for study: 20-45, 63-90, and 125-150 µm. As the second phase of our effort we used scanning electron microscopy imaging and x-ray diffraction to characterize the grain size distribution, and structural nature, respectively, of the mixtures. Visible and near-infrared reflectance spectra of the 63-90 micrometers grain size of the mixture samples are shown in Figure 1. We discuss the results of our measurements of these mixtures.

    Reiki is used by a growing number of people but little is known about the scientific basis for its use. The Touchstone Process was developed as an ongoing process to systematically analyze published, peer-reviewed studies of Reiki, the results being made accessible to the public online. Thirteen scientifically qualified experts in the field of Reiki were assembled into 3 teams to retrieve, evaluate, and summarize articles using standardized, piloted evaluation forms. Summaries of 26 Reiki articles, including strengths and weaknesses, were posted on a newly developed Web site (www.centerforreikiresearch.org), together with an overall summary of the status of Reiki research and guidelines for future research: The Touchstone Process determined that only 12 articles were based on a robust experimental design and utilized well-established outcome parameters. Of these articles, 2 provided no support, 5 provided some support, and 5 demonstrated strong evidence for the use of Reiki as a healing modality. There is a need for further high-quality studies in this area.

  20. Monitoring changes in seismic velocity related to an ongoing rapid inflation event at Okmok volcano, Alaska

    2015-01-01

    Okmok is one of the most active volcanoes in the Aleutian Arc. In an effort to improve our ability to detect precursory activity leading to eruption at Okmok, we monitor a recent, and possibly ongoing, GPS-inferred rapid inflation event at the volcano using ambient noise interferometry (ANI). Applying this method, we identify changes in seismic velocity outside of Okmok’s caldera, which are related to the hydrologic cycle. Within the caldera, we observe decreases in seismic velocity that are associated with the GPS-inferred rapid inflation event. We also determine temporal changes in waveform decorrelation and show a continual increase in decorrelation rate over the time associated with the rapid inflation event. Themagnitude of relative velocity decreases and decorrelation rate increases are comparable to previous studies at Piton de la Fournaise that associate such changes with increased production of volatiles and/ormagmatic intrusion within the magma reservoir and associated opening of fractures and/or fissures. Notably, the largest decrease in relative velocity occurs along the intrastation path passing nearest to the center of the caldera. This observation, along with equal amplitude relative velocity decreases revealed via analysis of intracaldera autocorrelations, suggests that the inflation sourcemay be located approximately within the center of the caldera and represent recharge of shallow magma storage in this location. Importantly, there is a relative absence of seismicity associated with this and previous rapid inflation events at Okmok. Thus, these ANI results are the first seismic evidence of such rapid inflation at the volcano.

    Full Text Available Planetary nebulas (PNs offer a unique tool to investigate the outer regions of massive galaxies because their strong [OIII]λ5007Å emission line makes them detectable out to several effective radii from the galaxy’s centre. We use a deep and extended spectroscopic survey of PNs (∼300 objects to study the spatial distribution, the kinematics and the stellar populations in the extended outer halo of the bright elliptical galaxy M87 (NGC 4486 in the Virgo cluster. We show that in the Virgo core, M87 stellar halo and the intracluster light are two distinct dynamical components, with different velocity distributions. Moreover the synergy of the PN kinematical information and the deep V/B-band photometry revealed an ongoing accretion event in the outer regions of M87. This satellite accretion represents a non-negligible perturbation of the halo properties: beyond 60 kpc the M87 halo is still growing with 60% of its light being added by the accretion event at the distance where it is detected.

    2017-08-22

    The purpose of the pilot study was to investigate the perceptions of online teaching efficacy of nursing faculty who teach courses in which 51% or more of the content is offered online. Bandura's psychological construct of self-efficacy served as the conceptual framework. The research survey was administered to nursing faculty in a state university system located in the southeastern United States of America, plus two private universities. The Michigan Nurse Educator's Sense of Efficacy for Online Teaching Scale, which contains 32 items that measure how nurse educators judge their current capabilities for teaching online nursing courses, was used to gather data. Overall, the scores reflected that faculty perceived themselves as quite a bit efficacious on a scale that ranged from 1 to 9. As nursing educators received more support in designing and implementing online courses, their efficacy increased. It is critical that faculty are supported on an ongoing basis to increase and develop online teaching skills in order to teach high-quality courses in online programs. Faculty members must also be recognized for their work, time, and commitment required to be effective online educators. The findings of this study revealed those participants who had a number of professional development supports and release time to develop online courses have a greater sense of efficacy.

  3. Molecular evidence for ongoing complementarity and horizontal gene transfer in endosymbiotic systems of mealybugs

    Sergio eLópez-Madrigal

    2014-08-01

    Full Text Available Intracellular bacterial supply of essential amino acids is common among sap-feeding insects, thus complementing the scarcity of nitrogenous compounds in plant phloem. This is also the role of the two mealybug endosymbiotic systems whose genomes have been sequenced. In the nested endosymbiotic system from Planococcus citri (Pseudococcinae, Candidatus Tremblaya princeps and Candidatus Moranella endobia cooperate to synthesize essential amino acids, while in Phenacoccus avenae (Phenacoccinae this function is performed by its single endosymbiont Candidatus Tremblaya phenacola. However, little is known regarding the evolution of essential amino acid supplementation strategies in other mealybug systems. To address this knowledge gap, we screened for the presence of six selected loci involved in essential amino acid biosynthesis in five additional mealybug species. We found evidence of ongoing complementarity among endosymbionts from insects of subfamily Pseudococcinae, as well as horizontal gene transfer affecting endosymbionts from insects of family Phenacoccinae, providing a more comprehensive picture of the evolutionary history of these endosymbiotic systems. Additionally, we report two diagnostic motifs to help identify invasive mealybug species.

    Norway was the country outside the former Soviet Union that received most radioactive fallout from the Chernobyl accident. The deposition was over 100 kBq/m 2 for Cs-137 is the most affected area. In addition, the extended use of unimproved pastures in the food production system resulted in high activity concentrations in foodstuffs. The effective ecological half-times in the Norwegian terrestrial systems have proven longer than earlier anticipated, and the Norwegian authorities still impose countermeasures for livestock at a large scale, even 18 years after the accident. We envisage the need for countermeasures for at least another decade to produce milk and meat that comply with food intervention limits. Specific measures, e.g. dietary advice and whole body counting, are used for the most vulnerable population groups. This talk presents the on-going management of contaminated areas in Norway and topics such as activity concentration levels, countermeasures used, compliance with regulations and financial issues are discussed.

    2011-01-01

    Ecstasy use has been associated with neurotoxicity and neurocognitive impairment in a variety of domains, including prospective memory (ProM), which involves the delayed execution of a previously encoded intention in response to a specific cue. The present study adopted the multiprocess theory of ProM to evaluate the hypothesis that ecstasy users would evidence differentially impaired ProM on longer versus shorter ongoing task delays. Ecstasy (n = 31) users, high-risk alcohol users (n = 21) and healthy nonusers (n = 31) completed the short (2-min) and long (15-min) delay ProM scales of the Memory for Intentions Screening Test. Results showed a significant group by ProM delay interaction, such that ecstasy users performed comparably to the comparison groups on short-delay trials, but were impaired on long-delay ProM, particularly for time-based cues. Among the ecstasy users, long-delay ProM was positively associated with risky decision-making, but not with retrospective memory or other aspects of executive functions. These findings suggest that ecstasy users may be particularly susceptible to deficits in strategic target monitoring and maintenance of cue-intention pairings over longer ProM delays. Findings are discussed in the context of their potential everyday functioning (e.g., academic, vocational) and treatment implications for ecstasy users. PMID:22047194

    To examine the effect of regular ongoing exercise lifestyle on mental and physical health in a group of independent community-dwelling Taiwanese older adults over a 2-year period. 197 older adults (mean age 72.5 years; 106 men and 91 women) who were independent in walking, instrumental and basic activities of daily living completed the baseline and a 2-year follow-up assessment. Older adults regularly performing exercises during the 2-year study period were grouped into regular exercise group; otherwise in the irregular exercise group. Baseline and follow-up assessments included a face-to-face interview and a battery of performance tests. The regular exercise group showed significantly less depression (P = 0.03) and tended to regress less on the performance tests (P = 0.025-0.410) across 2 years compared to the irregular exercise group. Regular exercise is important for maintaining or even improving mental and functional health, even for independent community-dwelling older adults. © 2010 The Authors.

    Pincham, Hannah L; Szucs, Dénes

    2012-10-01

    Neuroscience explanations of conscious access focus on neural events elicited by stimuli. In contrast, here, we used the attentional blink paradigm in combination with event-related brain potentials to examine whether the ongoing state of the brain before a stimulus can determine both conscious access and the poststimulus neural events associated with consciousness. Participants were required to detect 2 target letters from digit distractors while their brain activity was being recorded. Trials were classified based on whether the secondcritical target (T2) was detected. We found that T2-detection was predetermined by brain activity prior to the onset of the stimulation stream. Specifically, T2-detected trials were predicated by a frontocentral positive going deflection that started more than 200 ms before the stream began. Accurate T2 detection was also accompanied by enhanced poststimulus neural activity, as reflected by a larger P3b component. Furthermore, prestimulus and poststimulus markers of T2-detection were highly correlated with one another. We therefore argue that conscious experiences are shaped by potentially random fluctuations in neural activity. Overall, the results reveal that conscious access is underpinned by an important relationship involving predictive prestimulus neural activity and responsive poststimulus brain activity.

    The most impressive phenotypic appearance of sirenomelia is the presence of a 180°-rotated, axially positioned, single lower limb. Associated gastrointestinal and genitourinary anomalies are almost always present. This rare anomaly is still the subject of ongoing controversies concerning its nosology, pathogenesis, and possible genetic etiology. Sirenomelia can be part of a syndromic continuum, overlapping with other complex conditions including caudal dysgenesis and VATER/VACTERL/VACTERL-H associations, which could all be part of a heterogeneous spectrum, and originate from an early defect in blastogenesis. It is imaginable that different "primary field defects," whether or not genetically based, induce a spectrum of caudal malformations. In the current study, we review the contemporary hypotheses and conceptual approaches regarding the etiology and pathogenesis of sirenomelia, especially in the context of concomitant conditions. To expand on the latter, we included the external and internal dysmorphology of one third trimester sirenomelic fetus from our anatomical museum collection, in which multiple concomitant but discordant anomalies were observed compared with classic sirenomelia, and was diagnosed as VACTERL-H association with sirenomelia.

    ''Ischaemic memory'' is defined as a prolonged functional and/or biochemical alteration remaining after a particular episode of severe myocardial ischaemia. The biochemical alteration has been reported as metabolic stunning. Metabolic imaging has been used to detect the footprint left by previous ischaemic episodes evident due to delayed recovery of myocardial metabolism (persistent dominant glucose utilization with suppression of fatty acid oxidation). β-Methyl-p-[ 123 I]iodophenylpentadecanoic acid (BMIPP) is a single-photon emission computed tomography (SPECT) radiotracer widely used for metabolic imaging in clinical settings in Japan. In patients with suspected coronary artery disease but no previous myocardial infarction, BMIPP has shown acceptable diagnostic accuracy. In particular, BMIPP plays an important role in the identification of prior ischaemic insult in patients arriving at emergency departments with acute chest pain syndrome. Recent data also show the usefulness of 123 I-BMIPP SPECT for predicting cardiovascular events in patients undergoing haemodialysis. Similarly, SPECT or PET imaging with 18 F-FDG injected during peak exercise or after exercise under fasting conditions shows an increase in FDG uptake in postischaemic areas. This article will overview the roles of ischaemic memory imaging both under established indications and in ongoing investigations. (orig.)

  10. Business Associations, Conservative Networks, and the Ongoing Republican War over Medicaid Expansion.

    A major component of the Affordable Care Act involves the expansion of state Medicaid programs to cover the uninsured poor. In the wake of the 2012 Supreme Court decision upholding and modifying reform legislation, states can decide whether to expand Medicaid-and twenty states are still not proceeding as of August 2015. What explains state choices about participation in expansion, including governors' decisions to endorse expansion or not as well as final state decisions? We tackle this puzzle, focusing closely on outcomes and battles in predominantly Republican-led states. Like earlier scholars, we find that partisan differences between Democrats and Republicans are central, but we go beyond earlier analyses to measure added effects from two dueling factions within the Republican coalition: statewide business associations and cross-state networks of ideologically conservative organizations. Using both statistical modeling and case studies, we show that GOP-leaning or GOP-dominated states have been most likely to embrace the expansion when organized business support outweighs pressures from conservative networks. Our findings help make sense of ongoing state-level debates over a core part of health reform and shed new light on mounting policy tensions within the Republican Party.

    The increased incidence and the significant health burden associated with carcinoma of the prostate have led to substantial changes in its diagnosis over the past century. Despite technological advancements, the management of prostate cancer has become progressively more complex and controversial for both early and late-stage disease. The limitations and potential harms associated with the use of prostate-specific antigen (PSA) as a diagnostic marker have stimulated significant investigation of numerous novel biomarkers that demonstrate varying capacities to detect prostate cancer and can decrease unnecessary biopsies. However, only a few of these markers have been approved for specific clinical settings while the others have not been adequately validated for use. This review systematically and critically assesses ongoing issues and emerging challenges in the current state of prostate cancer diagnostic tools and the need for disruptive next generation tools based on analysis of combinations of these biomarkers to enhance predictive accuracy which will benefit clinical diagnostics and patient welfare.

    Protracted preoperative radio-chemotherapy with a 5-FU-based scheme, or a short course of preoperative radiotherapy without chemotherapy, are the standard neo-adjuvant treatments for resectable stage II-III rectal cancer. Local failure rates are low and reproducible, between 6 and 15% when followed with a 'Total Meso-rectal Excision'. Nevertheless, the therapeutic strategy needs to be improved: distant metastatic recurrence rates remain stable around 30 to 35%, while both sphincter and sexual sequels are still significant. The aim of the present paper was to analyse the ongoing trials listed on the following search engines: the Institut National du Cancer in France, the National Cancer Institute and the National Institute of Health in the United States, and the major cooperative groups. Keywords for the search were: 'rectal cancer', 'preoperative radiotherapy', 'phase II-III', 'preoperative chemotherapy', 'adjuvant chemotherapy' and 'surgery'. Twenty-three trials were selected and classified in different groups, each of them addressing a question of strategy: (1) place of adjuvant chemotherapy; (2) optimization of preoperative radiotherapy; (3) evaluation of new radiosensitization protocols and/or neo-adjuvant chemotherapy; (4) optimization of techniques and timing of surgery; (5) place of radiotherapy for non resectable or metastatic tumors.

    The population extinction pulse we describe here shows, from a quantitative viewpoint, that Earth's sixth mass extinction is more severe than perceived when looking exclusively at species extinctions. Therefore, humanity needs to address anthropogenic population extirpation and decimation immediately. That conclusion is based on analyses of the numbers and degrees of range contraction (indicative of population shrinkage and/or population extinctions according to the International Union for Conservation of Nature) using a sample of 27,600 vertebrate species, and on a more detailed analysis documenting the population extinctions between 1900 and 2015 in 177 mammal species. We find that the rate of population loss in terrestrial vertebrates is extremely high-even in "species of low concern." In our sample, comprising nearly half of known vertebrate species, 32% (8,851/27,600) are decreasing; that is, they have decreased in population size and range. In the 177 mammals for which we have detailed data, all have lost 30% or more of their geographic ranges and more than 40% of the species have experienced severe population declines (>80% range shrinkage). Our data indicate that beyond global species extinctions Earth is experiencing a huge episode of population declines and extirpations, which will have negative cascading consequences on ecosystem functioning and services vital to sustaining civilization. We describe this as a "biological annihilation" to highlight the current magnitude of Earth's ongoing sixth major extinction event.

    Full Text Available Background. Insulin resistance (IR is part of the metabolic syndrome (Mets that develops after lifestyle changes and obesity. Although the association between Mets and myocardial injury is well known, the effect of IR on myocardial damage remains unclear. Methods and Results. We studied 2200 normal subjects who participated in a community-based health check in the town of Takahata in northern Japan. The presence of IR was assessed by homeostasis model assessment ratio, and the serum level of heart-type fatty acid binding protein (H-FABP was measured as a maker of silent and ongoing myocardial damage. H-FABP levels were significantly higher in subjects with IR and Mets than in those without metabolic disorder regardless of gender. Multivariate logistic analysis showed that the presence of IR was independently associated with latent myocardial damage (odds ratio: 1.574, 95% confidence interval 1.1–2.3 similar to the presence of Mets. Conclusions. In a screening of healthy subjects, IR and Mets were similarly related to higher H-FABP levels, suggesting that there may be an asymptomatic population in the early stages of metabolic disorder that is exposed to myocardial damage and might be susceptible to silent heart failure.

  15. Level of ubiquitinated histone H2B in chromatin is coupled to ongoing transcription

    Davie, J.R.; Murphy, L.C.

    1990-01-01

    The relationship between transcription and ubiquitination of the histones was investigated. Previous studies have shown that ubiquitinated (u) histone H2B and, to a lesser extend, mono- and polyubiquitinated histone H2A are enriched in transcriptionally active gene-enriched chromatin fractions. Here, the authors show that treatment of T-47D-5 human breast cancer cells with actinomycin D or 5,6-dichloro-1-β-D-ribofuranosylbenzimidazole, inhibitors of heterogeneous nuclear RNA synthesis, selectively reduced the level of uH2B, but not uH2A, uH2A.Z, or polyubiquitinated H2A, in chromatin. Treatment of the cells with low levels of actinomycin D slightly reduced the level of uH2B, suggesting that inhibition of ribosomal RNA synthesis does not have a profound effect on the level of uH2B in chromatin. These results demonstrate that maintenance of the levels of uH2B in chromatin is dependent upon ongoing transcription, particularly the synthesis of hnRNA. Thus, histone H2B would be ubiquitinated when the nucleosome was opened during transcription. Ubiquitination of histone H2B may impede nucleosome refolding, facilitating subsequent rounds of transcription

    2012-02-01

    BACKGROUND: Early discharge care and self-management education, although effective in the management of chronic obstructive pulmonary disease (COPD), do not typically reduce hospital re-admission rates for exacerbations of the disease. We hypothesized that a respiratory outreach programme that comprises early discharge care followed by continued rapid-access out-patient support would reduce the need for hospital readmission in these patients. METHODS: Two hundred and forty-six patients, acutely admitted with exacerbations of COPD, were recruited to the respiratory outreach programme that included early discharge care, follow-up education, telephone support and rapid future access to respiratory out-patient clinics. Sixty of these patients received self-management education also. Emergency department presentations and admission rates were compared at six and 12 months after, compared to prior to, participation in the programme for the same patient cohort. RESULTS: The frequency of both emergency department presentations and hospital admissions was significantly reduced after participation in the programme. CONCLUSIONS: Provision of a respiratory outreach service that includes early discharge care, followed by education, telephone support and ongoing rapid access to out-patient clinics is associated with reduced readmission rates in COPD patients.

    Humans are highly sensitive to statistical regularities in their environment. This phenomenon, usually referred as statistical learning, is most often assessed using post-learning behavioural measures that are limited by a lack of sensibility and do not monitor the temporal dynamics of learning. In the present study, we used magnetoencephalographic frequency-tagged responses to investigate the neural sources and temporal development of the ongoing brain activity that supports the detection of regularities embedded in auditory streams. Participants passively listened to statistical streams in which tones were grouped as triplets, and to random streams in which tones were randomly presented. Results show that during exposure to statistical (vs. random) streams, tritone frequency-related responses reflecting the learning of regularities embedded in the stream increased in the left supplementary motor area and left posterior superior temporal sulcus (pSTS), whereas tone frequency-related responses decreased in the right angular gyrus and right pSTS. Tritone frequency-related responses rapidly developed to reach significance after 3 min of exposure. These results suggest that the incidental extraction of novel regularities is subtended by a gradual shift from rhythmic activity reflecting individual tone succession toward rhythmic activity synchronised with triplet presentation, and that these rhythmic processes are subtended by distinct neural sources.

  19. Investigation of exposure to Extremely Low Frequency (ELF) magnetic and electric fields: Ongoing animal studies

    1994-03-01

    There is now convincing evidence from a large number of laboratories, that exposure to extremely low frequency (ELF) magnetic and electric fields produces biological responses in animals. Many of the observed effects appear to be directly or indirectly associated with the neural or neuroendocrine systems. Such effects include increased neuronal excitability, chemical and hormonal changes in the nervous system, altered behavioral responses, some of which are related to sensing the presence of the field, and changes in endogenous biological rhythms. Additional indices of general physiological status appear relatively unaffected by exposure, although effects have occasionally been described in bone growth and fracture repair, reproduction and development, and immune system function. A major current emphasis in laboratory research is to determine whether or not the reported epidemiological studies that suggest an association between EMF exposure and risk of cancer are supported in studies using animal models. Three major challenges exist for ongoing research: (1) knowledge about the mechanisms underlying observed bioeffects is incomplete, (2) researchers do not as yet understand what physical aspects of exposure produce biological responses, and (3) health consequences resulting from ELF exposure are unknown. Although no animal studies clearly demonstrate deleterious effects of ELF fields, several are suggestive of potential health impacts. From the perspective of laboratory animal studies, this paper will discuss biological responses to ELF magnetic and/or electric field exposures.

  20. Ongoing cell death and immune influences on regeneration in the vestibular sensory organs

    Hair cells in the vestibular organs of birds have a relatively short life span. Mature hair cells appear to die spontaneously and are then quickly replaced by new hair cells that arise from the division of epithelial supporting cells. A similar regenerative mechanism also results in hair cell replacement after ototoxic damage. The cellular basis of hair cell turnover in the avian ear is not understood. We are investigating the signaling pathways that lead to hair cell death and the relationship between ongoing cell death and cell production. In addition, work from our lab and others has demonstrated that the avian inner ear contains a resident population of macrophages and that enhanced numbers of macrophages are recruited to sites of hair cells lesions. Those observations suggest that macrophages and their secretory products (cytokines) may be involved in hair cell regeneration. Consistent with that suggestion, we have found that treatment with the anti-inflammatory drug dexamethasone reduces regenerative cell proliferation in the avian ear, and that certain macrophage-secreted cytokines can influence the proliferation of vestibular supporting cells and the survival of statoacoustic neurons. Those results suggest a role for the immune system in the process of sensory regeneration in the inner ear.

    Full Text Available Recent research indicates a definite positive impact on treatment outcomes when an integrative approach that focuses on symptom control and quality of life is provided along with the standard therapeutic regimens. However implementation or practice of this approach is not seen widely due to the culture of medical training and practice. This article presents the initial development of a program for incorporating integrative care principles into an ongoing comprehensive cancer care program at a tertiary centre. The key purpose of the program being to develop, facilitate, and establish comprehensive and holistic processes including palliative care principles, that would positively enhance the quantity and quality of life of the person with disease, as well as create an environment that reflects and sustains this approach. The vision, objectives, goals, strategies, activities and results within the 7 months of implementation are documented. The new learnings gained during the process have also been noted in the hope that the model described may be used to conceptualize similar care giving facilities in other centres.

While the commissioning to exploit its full potential is still ongoing, there are plans to upgrade its components to reach instantaneous luminosities beyond the initial design value after 2016. A corresponding upgrade of the innermost part of the CMS detector, the pixel detector, is needed. A full replacement of the pixel detector is planned in 2016. It will not only address limitations of the present system at higher data rates, but will aggressively lower the amount of material inside the fiducial tracking volume which will lead to better tracking and b-tagging performance. This article gives an overview of the project and illuminates the motivations and expected improvements in the detector performance.

    Safety standards and best practices do exist in the field of cryogenics but, as in most domains, they are generally inserted in a few ‘envelope’ cases commonly used in the industry, whereas applicability to the particularity of research facilities are not fully tailored to its needs. The main objective in these cases is to find a harmonised approach, based on lessons learnt and scientific knowledge. The Kryolize Project was created in order to produce tools with a harmonized approach to size pressure relief devices for cryogenic applications. In view of disseminating such tools to other institutes and industrial partners, the project was submitted to CERN’s KT Fund committee. This talk will focus on the process and deliverables of the KT-Funded Kryolize project, including the method on how to cope with the sizing of pressure relief devices and the R&D collaboration agreement between CERN and Karlsruhe Institute of Technology for an experimental programme.

    The Bureau of Reclamation is a Federal agency tasked with developing and managing water supply and hydropower projects in the Western U.S. Climate and hydrologic variability and change significantly impact management actions and outcomes across Reclamation's programs and initiatives, including water resource planning and operations, infrastructure design and maintenance, hydropower generation, and ecosystem restoration, among others. Planning, design, and implementation of these programs therefore requires consideration of future climate and hydrologic conditions will impact program objectives. Over the past decade, Reclamation and other Federal agencies have adopted new guidelines, directives, and mandates that require consideration of climate change in water resources planning and decision making. Meanwhile, the scientific community has developed a large number of climate projections, along with an array of models, methods, and tools to facilitate consideration of climate projections in planning and decision making. However, water resources engineers, planners, and decision makers continue to face challenges regarding how best to use the available data and tools to support major decisions, including decisions regarding infrastructure investments and long-term operating criteria. This presentation will discuss recent and ongoing research towards understanding, improving, and expanding consideration of climate projections and related uncertainties in Federal water resources planning and decision making. These research efforts address a variety of challenges, including: How to choose between available climate projection datasets and related methods, models, and tools—many of which are considered experimental or research tools? How to select an appropriate decision framework when design or operating alternatives may differ between climate scenarios? How to effectively communicate results of a climate impacts analysis to decision makers? And, how to improve

  16. Contemporary views on selective mutism

    Dimoski Sanja

    2016-01-01

    Full Text Available The aim of this paper is to review contemporary literature on selective mutism (SM, available in our language. The paper includes a contemporary definition of the disorder, previous studies of selective mutism, theories about its origin, and treatment. SM is a disorder that occurs in childhood, when a child's speech is selectively lacking in certain social situations. School is the context in which the disorder is typically manifested, which is why SM is often diagnosed only after children start school. The paper gives a historical account of changes in views on this disorder. Modern conceptions emphasize selective inability of children to spontaneously and successfully express themselves verbally. In researching SM, case studies on children who have selective mutism are most commonly published. Etiological factors are not precisely defined, and different conceptions give their interpretations depending on various theoretical frameworks. Some studies consistently indicate a relation between SM and social anxiety, and some with opposing behavior and delays in language development. Based on theoretical explanations of SM, psychological interventions (behavioral and cognitive-behavioral, psychodynamic and projective techniques, counseling and family therapy are created. Modern treatment of selective mutism includes an eclectic approach and emphasizes the role of teachers and school in general. Future studies should deepen the knowledge about selective mutism, specify the methodological procedure and stimulate the individualized treatment of children with SM.

The principal object of study was a spray, namely a homogeneous second-order differential equation, or more generally a projective equivalence class of sprays. At around the same time, E. Cartan studied the same topic from a different point of view, by imagining a projective space attached to a manifold, or, more generally, attached to a `manifold of elements'; the infinitesimal `glue' may be interpreted in modern language as a Cartan projective connection on a principal bundle. This paper describes the geometrical relationship between these two points of view.

    This paper provides an overview of the on-going project COMPOSE, an EC co-funded project aiming to define, specify and validate an innovative mobile-services scenario in support of travellers, and to demonstrate the effectiveness of the new proposed location-based value-added services. COMPOSE is supported by organisations belonging to numerous categories covering, as a whole, the entire value-chain of infomobility services provision to the final user. The project team comprises, in addition to the affiliations of the authors, also Teleatlas (NL), ARS T&TT (NL), Alcatel-Bell Space (B), Skysoft (P), Hitech Marketing (A) and MobileGis (IR). The paper describes the services that will be offered to users, encompassing both the pre-trip and the on-trip framework, presents the overall hybrid system architecture also including a via-satellite component based upon the Wideband-CDMA (W-CDMA) technique adopted in UMTS, discusses the access solutions envisaged for that component permitting multiple feeder-link stations to share the CDMA multiplex capacity by directly transmitting their codes to the satellite, and illustrates the results of some computer simulations intended to assess the performance of said access solutions, with regard to the effects of the inevitable up- link frequency errors and transponder non-linearity.

    In the late 1960's and 1970's it was recognised that pollutants emanating from the abandoned Rum jungle uranium mine in the Northern Territory of Australia were responsible for severe environmental degradation of the Finniss River system. Products of acid mine drainage and low level radioactive material released from the tailings dam resulted in the virtual absence of flora and fauna species for ten kilometres downstream of the mine. In 1982 a joint Federal and Northern Territory government project was established to rehabilitate the abandoned Rum Jungle site. This project successfully achieved a major reduction in surface water pollution, public health hazard, (including radiation levels), pollution levels in the Open Cut water bodies and aesthetic improvement, including revegetation. Monitoring of the site is continuing up to the present date to determine the ongoing success of the project. This includes evaluation of the surface water quality, chemical activity and water balance within the overburden heaps, groundwater hydrology and an assessment of revegetation success, erosion control structures and cover stability. This document presents the results of monitoring activities conducted between 1986 and 1988 and outlines management and maintenance programs during that time. 36 refs., 40 figs., 47 tabs., 11 ills

    A new hydroelectric project is being proposed on the Peace River in the vicinity of Dunvegan, Alberta, by Glacier Power. The proposal calls for a low head, run-of-the-river hydroelectric power plant which would comprise a powerhouse containing 40 Kaplan turbines, a weir section, two fishways and a boat lock. The capacity of the generating plant would be 80 MW. As per established guidelines, the review process was initiated in July 1999 and is ongoing. Stakeholders, government agencies, both at the federal and provincial levels, are involved in the review process. The potential effects on the ice regime, fish passage and fish mortality and bank stability are the issues that have warranted the most attention to date. Scheduled to begin on October 2, 2001, a public hearing on the project has been arranged by the Alberta Energy and Utilities Board. The objective sought by Glacier Power is to have the project certified as being a green-power plant. Green power is defined as power produced from renewable sources with low environmental impact. The production of power with minimal environmental impacts is being encouraged in Alberta by Glacier Power, which sells power for a premium. 6 refs., 4 figs

    Progress in analytical ultracentrifugation (AUC) has been hindered by obstructions to hardware innovation and by software incompatibility. In this paper, we announce and outline the Open AUC Project. The goals of the Open AUC Project are to stimulate AUC innovation by improving instrumentation, detectors, acquisition and analysis software, and collaborative tools. These improvements are needed for the next generation of AUC-based research. The Open AUC Project combines on-going work from several different groups. A new base instrument is described, one that is designed from the ground up to be an analytical ultracentrifuge. This machine offers an open architecture, hardware standards, and application programming interfaces for detector developers. All software will use the GNU Public License to assure that intellectual property is available in open source format. The Open AUC strategy facilitates collaborations, encourages sharing, and eliminates the chronic impediments that have plagued AUC innovation for the last 20 years. This ultracentrifuge will be equipped with multiple and interchangeable optical tracks so that state-of-the-art electronics and improved detectors will be available for a variety of optical systems. The instrument will be complemented by a new rotor, enhanced data acquisition and analysis software, as well as collaboration software. Described here are the instrument, the modular software components, and a standardized database that will encourage and ease integration of data analysis and interpretation software.

    Recent evidence from functional magnetic resonance imaging suggests that cortical hemodynamic responses coincide in different subjects experiencing a common naturalistic stimulus. Here we utilize neural responses in the electroencephalogram (EEG) evoked by multiple presentations of short film clips to index brain states marked by high levels of correlation within and across subjects. We formulate a novel signal decomposition method which extracts maximally correlated signal components from multiple EEG records. The resulting components capture correlations down to a one-second time resolution, thus revealing that peak correlations of neural activity across viewings can occur in remarkable correspondence with arousing moments of the film. Moreover, a significant reduction in neural correlation occurs upon a second viewing of the film or when the narrative is disrupted by presenting its scenes scrambled in time. We also probe oscillatory brain activity during periods of heightened correlation, and observe during such times a significant increase in the theta band for a frontal component and reductions in the alpha and beta frequency bands for parietal and occipital components. Low-resolution EEG tomography of these components suggests that the correlated neural activity is consistent with sources in the cingulate and orbitofrontal cortices. Put together, these results suggest that the observed synchrony reflects attention- and emotion-modulated cortical processing which may be decoded with high temporal resolution by extracting maximally correlated components of neural activity.

    Prior to the introduction of the Southern District Health Board's reconfigured Community Oral Health Service in Otago, a project was undertaken with parents to investigate their knowledge, understanding and views of the historical School Dental Service and of the Community Oral Health Service that was being introduced. Focus groups were run during 2011 in ten selected schools (parents with children in years 1-8) across two areas in Otago to represent ur ban and rural settings and to represent parents who were already travelling to dental services. Parents valued the traditional School Dental Service in Otago highly, generally agreeing that the service based in schools was accessible and convenient for parents and children. Rural parents who had always taken their children to dental appointments viewed it as a normal process, accepting that there could not be a service located in every school. Parents were aware that facilities were out-of-date. They highlighted the challenges of locating therapists since they started moving from school to school in the later 1990s and felt it was difficult for children seeing different therapists at each recall. There were diverse views on the proposed new system. Some parents felt that school-aged children should go to dental clinics on their own or with peers, while other parents welcomed the opportunity to attend when their child was having health care. It appears that the Community Oral Health Services should have an ongoing process to seek the views of parents and children about the service.

  7. Massive Star Clusters in Ongoing Galaxy Interactions: Clues to Cluster Formation

    2003-09-01

    We present HST WFPC2 observations, supplemented by ground-based Hα data, of the star-cluster populations in two pairs of interacting galaxies selected for being in very different kinds of encounters seen at different stages. Dynamical information and n-body simulations provide the details of encounter geometry, mass ratio, and timing. In NGC 5752/4 we are seeing a weak encounter, well past closest approach, after about 2.5×108 yr. The large spiral NGC 5754 has a normal population of disk clusters, while the fainter companion NGC 5752 exhibits a rich population of luminous clusters with a flatter luminosity function. The strong, ongoing encounter in NGC 6621/2, seen about 1.0×108 yr past closest approach between roughly equal-mass galaxies, has produced an extensive population of luminous clusters, particularly young and luminous in a small region between the two nuclei. This region is dynamically interesting, with such a strong perturbation in the velocity field that the rotation curve reverses sign. From these results, in comparison with other strongly interacting systems discussed in the literature, cluster formation requires a threshold level of perturbation, with stage of the interaction a less important factor. The location of the most active star formation in NGC 6621/2 draws attention to a possible role for the Toomre stability threshold in shaping star formation in interacting galaxies. The rich cluster populations in NGC 5752 and NGC 6621 show that direct contact between gas-rich galaxy disks is not a requirement to form luminous clusters and that they can be triggered by processes happening within a single galaxy disk (albeit triggered by external perturbations). Based on observations with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555.

    Interactions between pairs of isolated dwarf galaxies provide a critical window into low-mass hierarchical, gas-dominated galaxy assembly and the build-up of stellar mass in low-metallicity systems. We present the first Very Large Telescope/Multi Unit Spectroscopic Explorer (VLT/MUSE) optical integral field unit (IFU) observations of the interacting dwarf pair dm1647+21 selected from the TiNy Titans survey. The H α emission is widespread and corresponds to a total unobscured star formation rate (SFR) of 0.44 M {sub ⊙} yr{sup −1}, which is 2.7 times higher than the SFR inferred from Sloan Digital Sky Survey (SDSS) data. The implied specific SFR (sSFR) for the system is elevated by more than an order of magnitude above non-interacting dwarfs in the same mass range. This increase is dominated by the lower-mass galaxy, which has a sSFR enhancement of >50. Examining the spatially resolved maps of classic optical line diagnostics, we find that the interstellar medium (ISM) excitation can be fully explained by star formation. The velocity field of the ionized gas is not consistent with simple rotation. Dynamical simulations indicate that the irregular velocity field and the stellar structure is consistent with the identification of this system as an ongoing interaction between two dwarf galaxies. The widespread, clumpy enhancements in the star formation in this system point to important differences in the effect of mergers on dwarf galaxies, compared to massive galaxies; rather than the funneling of gas to the nucleus and giving rise to a nuclear starburst, starbursts in low-mass galaxy mergers may be triggered by large-scale ISM compression, and thus may be more distributed.

    Innovative nuclear technology applications have emerged in recent years and triggered an unprecedented interest of different communities of scientists worldwide, concerned by the multidisciplinary scientific, technical and engineering aspects of such applications. ADS (Accelerator Driven Systems, for the transmutation of highly radiotoxic nuclear waste), EA (Energy Amplifiers, for the production of energy), Spallation Neutron Sources (for multiple applications such as in Bio-Sciences, Medicine, Material Science), Radioactive Ion Beams (of relevance for fundamental Nuclear Physics and Astrophysics, for applications in Medicine, amongst many others) are examples of applications that address a set of common multidisciplinary, leading edge and cross-cutting issues and research topics. Other applications being considered for High-Energy Physics purposes consist on facilities aiming at producing intense neutrino beams.The sustainability of nuclear energy as an economically competitive, environmentally friend and proliferation resistant technology to meet mankind's growing energy demand has imposed in recent years the consideration of new (Generation IV) or non-conventional types of nuclear reactors, operating with non-standard coolants, higher-energy neutron spectra, higher temperatures, amongst other issues. The safety and operational aspects of these nuclear energy systems share with the nuclear technology applications previously referred (ADS, EA, SNS, etc.) a set of common scientific and technical issues.In this paper, the scientific, technical and engineering topics and issues of relevance for the implementation and deployment of some of the systems previously described are briefly presented. A set of selected major on-going R and D programmes and experiments involving international collaborations of scientists and consortia of institutions are succinctly described

  10. Multiple sites and actions of gabapentin-induced relief of ongoing experimental neuropathic pain.

    Gabapentin (GBP) is a first-line therapy for neuropathic pain, but its mechanisms and sites of action remain uncertain. We investigated GBP-induced modulation of neuropathic pain following spinal nerve ligation (SNL) in rats. Intravenous or intrathecal GBP reversed evoked mechanical hypersensitivity and produced conditioned place preference (CPP) and dopamine (DA) release in the nucleus accumbens (NAc) selectively in SNL rats. Spinal GBP also significantly inhibited dorsal horn wide-dynamic-range neuronal responses to a range of evoked stimuli in SNL rats. By contrast, GBP microinjected bilaterally into the rostral anterior cingulate cortex (rACC), produced CPP, and elicited NAc DA release selectively in SNL rats but did not reverse tactile allodynia and had marginal effects on wide-dynamic-range neuronal activity. Moreover, blockade of endogenous opioid signaling in the rACC prevented intravenous GBP-induced CPP and NAc DA release but failed to block its inhibition of tactile allodynia. Gabapentin, therefore, can potentially act to produce its pain relieving effects by (a) inhibition of injury-induced spinal neuronal excitability, evoked hypersensitivity, and ongoing pain and (b) selective supraspinal modulation of affective qualities of pain, without alteration of reflexive behaviors. Consistent with previous findings of pain relief from nonopioid analgesics, GBP requires engagement of rACC endogenous opioid circuits and downstream activation of mesolimbic reward circuits reflected in learned pain-motivated behaviors. These findings support the partial separation of sensory and affective dimensions of pain in this experimental model and suggest that modulation of affective-motivational qualities of pain may be the preferential mechanism of GBP's analgesic effects in patients.

  11. Living on the edge: timing of Rand Flora disjunctions congruent with ongoing aridification in Africa.

    The Rand Flora is a well-known floristic pattern in which unrelated plant lineages show similar disjunct distributions in the continental margins of Africa and adjacent islands-Macaronesia-northwest Africa, Horn of Africa-Southern Arabia, Eastern Africa, and Southern Africa. These lineages are now separated by environmental barriers such as the arid regions of the Sahara and Kalahari Deserts or the tropical lowlands of Central Africa. Alternative explanations for the Rand Flora pattern range from vicariance and climate-driven extinction of a widespread pan-African flora to independent dispersal events and speciation in situ. To provide a temporal framework for this pattern, we used published data from nuclear and chloroplast DNA to estimate the age of disjunction of 17 lineages that span 12 families and nine orders of angiosperms. We further used these estimates to infer diversification rates for Rand Flora disjunct clades in relation to their higher-level encompassing lineages. Our results indicate that most disjunctions fall within the Miocene and Pliocene periods, coinciding with the onset of a major aridification trend, still ongoing, in Africa. Age of disjunctions seemed to be related to the climatic affinities of each Rand Flora lineage, with sub-humid taxa dated earlier (e.g., Sideroxylon) and those with more xeric affinities (e.g., Campylanthus) diverging later. We did not find support for significant decreases in diversification rates in most groups, with the exception of older subtropical lineages (e.g., Sideroxylon, Hypericum, or Canarina), but some lineages (e.g., Cicer, Campylanthus) showed a long temporal gap between stem and crown ages, suggestive of extinction. In all, the Rand Flora pattern seems to fit the definition of biogeographic pseudocongruence, with the pattern arising at different times in response to the increasing aridity of the African continent, with interspersed periods of humidity allowing range expansions.

  12. Hippocampal subfield and medial temporal cortical persistent activity during working memory reflects ongoing encoding

    Full Text Available Previous neuroimaging studies support a role for the medial temporal lobes (MTL in maintaining novel stimuli over brief working memory (WM delays, and suggest delay period activity predicts subsequent memory. Additionally, slice recording studies have demonstrated neuronal persistent spiking in entorhinal cortex (EC, perirhinal cortex (PrC, and hippocampus (CA1, CA3, subiculum. These data have led to computational models that suggest persistent spiking in parahippocampal regions could sustain neuronal representations of sensory information over many seconds. This mechanism may support both WM maintenance and encoding of information into long term episodic memory. The goal of the current study was to use high-resolution fMRI to elucidate the contributions of the MTL cortices and hippocampal subfields to WM maintenance as it relates to later episodic recognition memory. We scanned participants while they performed a delayed match to sample task with novel scene stimuli, and assessed their memory for these scenes post-scan. We hypothesized stimulus-driven activation that persists into the delay period—a putative correlate of persistent spiking—would predict later recognition memory. Our results suggest sample and delay period activation in the parahippocampal cortex (PHC, PrC, and subiculum (extending into DG/CA3 and CA1 was linearly related to increases in subsequent memory strength. These data extend previous neuroimaging studies that have constrained their analysis to either the sample or delay period by modeling these together as one continuous ongoing encoding process, and support computational frameworks that predict persistent activity underlies both WM and episodic encoding.

  13. The EU legislation on "GMOs" between nonsense and protectionism: An ongoing Schumpeterian chain of public choices.

    2017-01-02

    The EU regulation of agricultural biotechnology is botched and convoluted: the pseudo-concept of "Genetically Modified Organisms" has no coherent semantic or scientific content. The reasons of the paradox by which the cultivation of "GMOs" is substantially banned in Europe, while enormous quantities of recombinant-DNA cereals and legumes are imported to be used as feedstuff, are explained. The Directive 2015/412, giving Member states the choice to refuse the cultivation of genetically engineered crops at a national or local level, paves the way for a mosaic-like, Harlequinesque form of protectionism: nothing resembling a well-regulated free market. In the meantime, importation of "GMO" feed goes on at full speed all over Europe. A proposal by the Commission to adjust the rules on importation according to those for cultivation has been rejected by the Parliament.This dynamics may be seen as an ongoing "Schumpeterian" chain of public choices: the calculus of consent drives politicians more than a science-based approach to law-making.  The EU should restart from scratch with the right concept, i.e. the careful examination of the pros and cons, the costs and benefits of each new agricultural product ("GMO" or otherwise), freely cultivated and/or imported, assessed case by case, at last acknowledging that the biotech processes used to create new varieties are of no practical or legal relevance. In doing so, the EU would pursue its stated "better regulation" approach, cancelling any sectoral and sectarian regulation.

    Surgical treatment for rectal cancer (RC) can result in an intestinal ostomy that requires lifelong adaptation and investment of physical, cognitive, and financial resources. However, little is known about the extent of ongoing challenges related to ostomy self-care among long-term RC survivors. We analyzed the prevalence of self-reported ostomy self-care challenges and the physical and environmental factors that can support or undermine ostomy self-care. We mailed surveys to long-term (≥ 5 years post-diagnosis) RC survivors, including 177 adults with ostomies who were members of integrated health systems in northern California, Oregon, and Washington State. Potential participants were identified through tumor registries. Data were also extracted from electronic health records. The response rate was 65%. The majority of respondents were male (67%), and the mean age was 75 years. Sixty-three percent of respondents reported at least one ostomy self-care challenge. The most common challenges were leakage or skin problems around the ostomy and needing to change the pouching system too frequently. Twenty-two percent reported difficulty caring for their ostomy. Younger age and higher BMI were consistently related to ostomy self-care challenges. The majority of RC survivors reported ostomy-related self-care challenges, and 31% experienced problems across multiple domains of ostomy self-care. In addition, most survivors reported significant physical challenges that could lead to ostomy-related disability. Although the participants surveyed had access to ostomy care nurses, the care gaps we found suggest that additional work is needed to understand barriers to ostomy care, reduce unmet needs, and improve well-being among this group.

    Since about four decades, gamma evaluation codes for plutonium and uranium isotope abundance measurements are a key component of international, regional and domestic safeguards inspections. However, the development of these codes still relies upon a very limited number of experts. This led the safeguards authorities to express concerns, and to request continuity of knowledge and maintenance capability for the codes. The presentation describes initiatives undertaken in the past ten years to ensure ongoing support for the isotopic codes. As a follow-up to the 2005 international workshop, the IAEA issued a roadmap for future developments of gamma codes, followed by a request for support in this field to several MSSP's (namely JNT A 01684). The international working group on gamma spectrometry techniques for U and Pu isotopics (IWG-GST) was launched by the European, French and US MSSPs in 2007, to respond to the needs expressed by the IAEA and other national or international inspectorates. Its activities started with the organization in 2008 of a workshop on gamma spectrometry analysis codes for U and Pu isotopics. The working group is currently developing an international database of reference spectra that will be made available to the community of users and developers. In parallel, IRSN contributes to the JNT A 01684 by advising the IAEA on establishing a procedure for validating a new version of isotopics codes compared to the previous version. The most recent initiative, proposed by the IAEA, consists in organizing an inter-comparison exercise to assess the performances of U and Pu isotopics and mass assay techniques based on medium resolution gamma spectrometry (MRGS). All these initiatives contributed to the continuity of knowledge and maintenance of the gamma isotopic codes, but further efforts are needed to ensure the long-term sustainability of the codes.

    The BR2 reactor (Mol, Belgium) is a high-flux materials testing reactor. The fuel is 93% {sup 235}U enriched uranium. The nominal power ranges from 60 to 100 MW. The main features of the design are the following: 1) maximum neutron flux, thermal: 1.2 x 10{sup 15} n/cm{sup 2} s; fast (E > 0.1 MeV) : 8.4 x 10{sup 14} n /cm{sup 2} s; 2) great flexibility of utilization: the core configuration and operation mode can be adapted to the experimental loading; 3) neutron spectrum tailoring; 4) availability of five 200 mm diameter channels besides the standard channels (84 mm diameter); 5) access to the top and bottom covers of the reactor authorizing the irradiation of loops. The reactor is used to study the behaviour of fuel elements and structural materials intended for future nuclear power stations of several types (fission and fusion). Irradiations are carried out in connection with performance tests up to very high burn-up or neutron fluence as well as for safety experiments, power cycling experiments, and generally speaking, tests under off-normal conditions. Irradiations for nuclear transmutation (production of high specific activity radio-isotopes and transplutonium elements), neutron-radiography, use of beam tubes for physics studies, and gamma irradiations are also carried out. The BR2 is used in support of Belgian programs, at the request of utilities, industry and universities and in the framework of international agreements. The paper reviews the past and ongoing upgrading and enhancement of reactor capabilities as well as those under study or consideration, namely with regard to: reactor equipment, fuel elements, irradiation facilities, reactor operation conditions and long-term strategy.

  17. Ongoing changes in migration phenology and winter residency at Bracken Bat Cave.

    Bats play an important role in agroecology and are effective bioindicators of environmental conditions, but little is known about their fundamental migration ecology, much less how these systems are responding to global change. Some of the world's largest bat populations occur during the summer in the south-central United States, when millions of pregnant females migrate from lower latitudes to give birth in communal maternity colonies. Despite a relatively large volume of research into these colonies, many fundamental questions regarding their abundance-including their intra- and interseasonal variability-remain unanswered, and even estimating the size of individual populations has been a long-running challenge. Overall, monitoring these bat populations at high temporal resolution (e.g., nightly) and across long time spans (e.g., decades) has been impossible. Here, we show 22 continuous years of nightly population counts at Bracken Cave, a large bat colony in south-central Texas, enabling the first climate-scale phenological analysis. Using quantitative radar monitoring, we found that spring migration and the summer reproductive cycle have advanced by approximately 2 weeks over the study period. Furthermore, we quantify the ongoing growth of a newly-established overwintering population that indicates a system-wide response to changing environmental conditions. Our observations reveal behavioral plasticity in bats' ability to adapt to changing resource availability, and provide the first long-term quantification of their response to a changing climate. As aerial insectivores, these changes in bat phenology and propensity for overwintering indicate probable shifts in prey availability, with clear implications for pest management across wider regional agrisystems. © 2018 John Wiley & Sons Ltd.

We hypothesized that a respiratory outreach programme that comprises early discharge care followed by continued rapid-access out-patient support would reduce the need for hospital readmission in these patients.Methods: Two hundred and forty-six patients, acutely admitted with exacerbations of COPD, were recruited to the respiratory outreach programme that included early discharge care, followup education, telephone support and rapid future access to respiratory out-patient clinics. Sixty of these patients received self-management education also. Emergency department presentations and admission rates were compared at six and 12 months after, compared to prior to, participation in the programme for the same patient cohort.Results: The frequency of both emergency department presentations and hospital admissions was significantly reduced after participation in the programme.Conclusions: Provision of a respiratory outreach service that includes early discharge care, followed by education, telephone support and ongoing rapid access to out-patient clinics is associated with reduced readmission rates in COPD patients.Keywords: COPD management outreach, follow-up, out-patient clinics

    During the International Tapir Symposium 16-21 Oct 2011, the conservation of Baird's tapir (Tapirus bairdii) in Honduras received a boost with the signing of a memorandum of understanding between the Minister Director of the Honduran Institute of Conservation and Forestry (ICF) and the Tapir Specialist Group (TSG). Despite this agreement, accelerating levels of hunting and habitat loss continue to pose a threat to Baird's tapir in Honduras. An ongoing study in Cusuco National Park in northwestern Honduras has been monitoring changes in population dynamics of Baird's tapir since 2006 through the collection of occupancy data. The study has identified an increase in hunting pressure, coinciding with a drastic decline in the encounter rate with Baird's tapir spoor. Here, we examine the significance of a range of demographic variables on Baird's tapir occupancy in Cusuco National Park using the software PRESENCE, and simulate the effects of different management strategies on the future dynamics of the population using the stochastic simulation software VORTEX. The predictions of the theoretical population models are compared to observed changes in occupancy levels. We found that non-intervention resulted in the local extinction of Baird's tapir within a very short time frame, but that various intervention models enabled the population to recover to near carrying capacity. Occupancy and extinction probability were shown to respond markedly to the increase in hunting pressure; and occupancy models supported the future population predictions generated by VORTEX. Our study suggests that immediate intervention is required to reduce hunting pressure to near historical levels to prevent the imminent local extinction of the species. © 2012 Wiley Publishing Asia Pty Ltd, ISZS and IOZ/CAS.

    Amphibians are one of the most threatened animal groups, with 32% of species at risk for extinction. Given this imperiled status, is the disappearance of a large fraction of the Earth’s amphibians inevitable, or are some declining species more resilient than is generally assumed? We address this question in a species that is emblematic of many declining amphibians, the endangered Sierra Nevada yellow-legged frog (Rana sierrae). Based on >7,000 frog surveys conducted across Yosemite National Park over a 20-y period, we show that, after decades of decline and despite ongoing exposure to multiple stressors, including introduced fish, the recently emerged disease chytridiomycosis, and pesticides, R. sierrae abundance increased sevenfold during the study and at a rate of 11% per year. These increases occurred in hundreds of populations throughout Yosemite, providing a rare example of amphibian recovery at an ecologically relevant spatial scale. Results from a laboratory experiment indicate that these increases may be in part because of reduced frog susceptibility to chytridiomycosis. The disappearance of nonnative fish from numerous water bodies after cessation of stocking also contributed to the recovery. The large-scale increases in R. sierrae abundance that we document suggest that, when habitats are relatively intact and stressors are reduced in their importance by active management or species’ adaptive responses, declines of some amphibians may be partially reversible, at least at a regional scale. Other studies conducted over similarly large temporal and spatial scales are critically needed to provide insight and generality about the reversibility of amphibian declines at a global scale.
