    NASA/GRO grant NAG 5-2081, at the University of Chicago, has provided support for a broad program of theoretical research in nuclear astrophysics and related areas, with regard to gamma-ray and hard X-ray emission from classical nova explosions. This research emphasized the possible detection of 22Na gamma-ray line emission from nearby novae involving ONeMg white dwarfs, the detailed examination of 26Al production in novae, and the possible detection of the predicted early gamma ray emission from novae that arises from the decay of the short lived, positron emitting isotopes of CNO elements. Studies of nova related problems have consumed an increasing fraction of the Principal Investigator's research efforts over the past decade. Current research addresses problems associated with the standard model for the outbursts of the classical novae: the occurrence of thermonuclear runaways (TNR) in the accreted hydrogen rich envelopes on white dwarfs in close binary systems (see, e.g., the reviews by Truran 1982; and Shara 1989). Research in progress and planned for the next three years has three main objectives: (1) to gain an improved understanding of the early evolution of the light curves of, particularly, the fastest novae; (2) to gain an improved understanding of the relative importance of the various possible mechanisms of envelope hydrogen depletion (e.g. winds, common envelope driven mass loss, and nuclear burning) to the long term evolution of novae in outburst; and (3) to seek to provide a somewhat more definitive statement of the role of classical novae in nucleosynthesis. Our proposed 2-D studies of convection during the early phases of the TNR and our systematic attempt to incorporate an improved treatment of radiation hydrodynamics into the hydrodynamic code utilized in our calculations, are particularly relevant to the first of these objectives. Further 2-D studies of the effects of common envelope evolution are intended to provide more realistic constraints

    The Dalat Nuclear Research Reactor (DNRR) is a pool type research reactor which was reconstructed in 1982 from the previous 250 kW TRIGA-MARK II reactor. The reactor core, the control and instrumentation system, the primary and secondary cooling systems as well as other associated systems were newly designed and installed. The renovated reactor reached its initial criticality in November 1983 and attained its nominal power of 500 kW in February 1984. Since then DNRR has been operated safely. Retained structures of the former reactor such as the reactor aluminum tank, the graphite reflector, the thermal column, the horizontal beam tubes and the radiation concrete shielding are 35 years old. During the recent years, in-service inspection has been carried out, the reactor control and instrumentation system were renovated due to ageing and obsolescence of its components, reactor general inspection and refurbishment were performed. Efforts are being made to cope with ageing of old reactor components to maintain safe operation of the DNRR. (author)

    2016-11-01

    Full Text Available Introduction: The extent to which health sciences librarians are engaged in research is a little-studied question. This study assesses the research activities and attitudes of Medical Library Association (MLA members, including the influence of work affiliation. Methods: An online survey was designed using a combination of multiple-choice and open-ended questions and distributed to MLA members. Responses were analyzed using descriptive statistics, content analysis, and significance testing. The authors used statistical tools and categorized openended question topics by the constant comparative method, also applying the broad subject categories used in a prior study. Pearson’s chi-square analysis was performed on responses to determine significant differences among respondents employed in three different institutional environments. Results: Analysis showed that 79% of respondents read research articles at least once a month; 58% applied published research studies to practice; 44% had conducted research; 62% reported acting on research had enhanced their libraries; 38% had presented findings; and 34% had authored research articles. Hospital librarians were significantly less likely than academic librarians to have participated in research activities. Highly ranked research benefits, barriers, and competencies of health sciences librarians are described. Conclusions: Findings indicate that health sciences librarians are actively engaged in research activities. Practice implications for practitioners, publishers, and stakeholders are discussed. Results suggest that practitioners can use published research results and results from their own research to affect practice decisions and improve services. Future studies are needed to confirm and extend these findings, including the need for intervention studies to increase research and writing productivity.

    2007-12-01

    Students today have online access to nearly unlimited scientific information in an entirely unfiltered state. As such, they need guidance and training in identifying and assessing high-quality information resources for educational and research use. The extensive research data resources available online for the Izu-Bonin-Mariana (IBM) subduction system that have been developed with MARGINS Program and related NSF funding are an ideal venue for focused Web research exercises that can be tailored to a range of undergraduate geoscience courses. This presentation highlights student web research activities examining: a) The 2003-2005 eruptions of Anatahan Volcano in the Mariana volcanic arc. MARGINS-supported geophysical research teams were in the region when the eruption initiated, permitting a unique "event response" data collection and analysis process, with preliminary results presented online at websites linked to the MARGINS homepage, and ultimately published in a special issue of the Journal of Volcanology and Geothermal Research. In this activity, students will conduct a directed Web surf/search effort for information on and datasets from the Anatahan arc volcano, which they will use in an interpretive study of recent magmatic activity in the Mariana arc. This activity is designed as a homework exercise for use in a junior-senior level Petrology course, but could easily be taken into greater depth for the benefit of graduate-level volcanology or geochemistry offerings. b) Geochemical and mineralogical results from ODP Legs 125 and 195 focused on diapiric serpentinite mud volcanoes, which erupt cold, high pH fluids, serpentine muds, and serpentinized ultramafic clasts at a number of sites in the forearc region of the Mariana subduction zone. The focus of this activity is an examination of the trace element chemistry of the forearc serpentines and their associated upwelling porefluids as a means of understanding the roles of ionic radius, valence, and system

    Through collaborations between scientists and educators, the Consortium for Ocean Leadership developed a series of marine geosciences classroom activities and lesson plans -- including the Adopt-a-Microbe project, a collection of hands-on science lessons that use the sub-seafloor microbiology topics to provide engaging pathways for K-12 students to learn about the world around them. The goal of these activities has been to introduce youth to deep ocean exploration, inspire interest in microbial oceanography, and foster higher education goals and career paths in related sciences for our youth. From the beginning, these lessons were developed in close working relationships between scientists and educators, and the lessons geared towards middle school have been recently piloted with the intent to maximize sustained student interest in STEM topics. While teaching these units, educators used surveys, polls, group discussions, and interviews to shed light on correlations between student interest in STEM and their close proximity to exemplary and enthusiastic educators and student leaders who are active in STEM activities such as research projects and expeditions. Educators continue to use Adopt-a-Microbe and related expedition science-based lessons to explore the broader impacts of their professional development in the Geosciences on their students' professed interest in STEM.

    Bonanno, A; Karoff, C

    2014-01-01

    In asteroseismology an important diagnostic of the evolutionary status of a star is the small frequency separation which is sensitive to the gradient of the mean molecular weight in the stellar interior. It is thus interesting to discuss the classical age-activity relations in terms of this quantity. Moreover, as the photospheric magnetic field tends to suppress the amplitudes of acoustic oscillations, it is important to quantify the importance of this effect by considering various activity indicators. We propose a new class of age-activity relations that connects the Mt. Wilson $S$ index and the average scatter in the light curve with the small frequency separation and the amplitude of the p-mode oscillations. We used a Bayesian inference to compute the posterior probability of various empirical laws for a sample of 19 solar-like active stars observed by the Kepler telescope. We demonstrate the presence of a clear correlation between the Mt. Wilson $S$ index and the relative age of the stars as indicated by ...

    2012-09-05

    The Department of Energy’s High Temperature, Low Relative Humidity Membrane Program was begun in 2006 with the Florida Solar Energy Center (FSEC) as the lead organization. During the first three years of the program, FSEC was tasked with developing non-Nafion® proton exchange membranes with improved conductivity for fuel cells. Additionally, FSEC was responsible for developing protocols for the measurement of in-plane conductivity, providing conductivity measurements for the other funded teams, developing a method for through-plane conductivity and organizing and holding semiannual meetings of the High Temperature Membrane Working Group (HTMWG). The FSEC membrane research focused on the development of supported poly[perfluorosulfonic acid] (PFSA) – Teflon membranes and a hydrocarbon membrane, sulfonated poly(ether ether ketone). The fourth generation of the PFSA membrane (designated FSEC-4) came close to, but did not meet, the Go/No-Go milestone of 0.1 S/cm at 50% relative humidity at 120 °C. In-plane conductivity of membranes provided by the funded teams was measured and reported to the teams and DOE. Late in the third year of the program, DOE used this data and other factors to decide upon the teams to continue in the program. The teams that continued provided promising membranes to FSEC for development of membrane electrode assemblies (MEAs) that could be tested in an operating fuel cell. FSEC worked closely with each team to provide customized support. A logic flow chart was developed and discussed before MEA fabrication or any testing began. Of the five teams supported, by the end of the project, membranes from two of the teams were easily manufactured into MEAs and successfully characterized for performance. One of these teams exceeded performance targets, while the other requires further optimization. An additional team developed a membrane that shows great promise for significantly reducing membrane costs and increasing membrane lifetime.

    Full Text Available The development of antiviral drugs provides an excellent example of how basic and clinical research must be used together in order to achieve the final goal of treating disease. A Research Oriented Learning Activity was designed to help students to better understand how basic and clinical research can be combined toward a common goal. Through this project students gained a better understanding of the process of scientific research and increased their information literacy in the field of virology. The students worked as teams to research the many aspects involved in the antiviral drug design process, with each student becoming an "expert" in one aspect of the project. The Antiviral Drug Research Proposal (ADRP culminated with students presenting their proposals to their peers and local virologists in a poster session. Assessment data showed increased student awareness and knowledge of the research process and the steps involved in the development of antiviral drugs as a result of this activity.

    Although remarkable progress has been made in developing technologies for the clean and efficient utilization of coal, the biggest challenge in the utilization of coal is still the protection of the environment. Specifically, electric utilities face increasingly stringent restriction on the emissions of NO{sub x} and SO{sub x}, new mercury emission standards, and mounting pressure for the mitigation of CO{sub 2} emissions, an environmental challenge that is greater than any they have previously faced. The Utah Clean Coal Program addressed issues related to innovations for existing power plants including retrofit technologies for carbon capture and sequestration (CCS) or green field plants with CCS. The Program focused on the following areas: simulation, mercury control, oxycoal combustion, gasification, sequestration, chemical looping combustion, materials investigations and student research experiences. The goal of this program was to begin to integrate the experimental and simulation activities and to partner with NETL researchers to integrate the Program's results with those at NETL, using simulation as the vehicle for integration and innovation. The investigators also committed to training students in coal utilization technology tuned to the environmental constraints that we face in the future; to this end the Program supported approximately 12 graduate students toward the completion of their graduate degree in addition to numerous undergraduate students. With the increased importance of coal for energy independence, training of graduate and undergraduate students in the development of new technologies is critical.

    Full Text Available Activities play a guiding central role in occupational therapy, articulating to its utilization, the understanding and assessment of its capabilities in numerous and different interventions arising from this field. In this study, we aim to present the use of activities as a research methodology resource. Considering the pathways studied in a master’s research followed by a PhD work, some applications of this resource are reported as a powerful strategy of investigation for the occupational therapy researcher. It is about structuring, systematizing, and analyzing the activities proposed in professional practice by the theoretical and methodological rigor used in the research works. It emphasizes how the use of these activities can be considered important data, records, instruments and sources for different research methods, especially for qualitative analyses. Workshop activities were offered in the above mentioned studies; they were used as communication instruments and expressions of personal and collective experiences, supplying data to understand the actions of subjects and collectives. Furthermore, this strategy was applied as spaces of experimentation, learning and expression, where each participant was conceived as an active being of the process, in a way that the proposal could result in democratic experiences that reflected greater interest and participation, and a more complex presentation of the research data. It is worth mentioning that other methodological procedures, which substantiated the analyses and interpretation of the data collected, were also used. It was possible to conclude that activities, mainly as a qualitative research resource, constituted materialities in different languages and expressions that enriched the analyses arising from micro-realities, producing a repertoire of information that supported the interpretations required for the investigative processes.

    Multiple organizations within NASA and outside of NASA fund and participate in research related to extravehicular activity (EVA). In October 2015, representatives of the EVA Office, the Crew and Thermal Systems Division (CTSD), and the Human Research Program (HRP) at NASA Johnson Space Center agreed on a formal framework to improve multi-year coordination and collaboration in EVA research. At the core of the framework is an Integrated EVA Research Plan and a process by which it will be annually reviewed and updated. The over-arching objective of the collaborative framework is to conduct multi-disciplinary cost-effective research that will enable humans to perform EVAs safely, effectively, comfortably, and efficiently, as needed to enable and enhance human space exploration missions. Research activities must be defined, prioritized, planned and executed to comprehensively address the right questions, avoid duplication, leverage other complementary activities where possible, and ultimately provide actionable evidence-based results in time to inform subsequent tests, developments and/or research activities. Representation of all appropriate stakeholders in the definition, prioritization, planning and execution of research activities is essential to accomplishing the over-arching objective. A formal review of the Integrated EVA Research Plan will be conducted annually. External peer review of all HRP EVA research activities including compilation and review of published literature in the EVA Evidence Book is already performed annually. Coordination with stakeholders outside of the EVA Office, CTSD, and HRP is already in effect on a study-by-study basis; closer coordination on multi-year planning with other EVA stakeholders including academia is being actively pursued. Details of the current Integrated EVA Research Plan are presented including description of ongoing and planned research activities in the areas of: Benchmarking; Anthropometry and Suit Fit; Sensors; Human

    This report documents ground-water characterization field activities completed from August to December 1995 and in January 1996 at the Laboratory for Energy-Related Health Research (LEHR) in Davis, California. The ground water at LEHR is one of several operable units under investigation by Pacific Northwest National Laboratory for the US Department of Energy. The purpose of this work was to further characterize the hydrogeology beneath the LEHR site, with the primary focus on ground water. The objectives were to estimate hydraulic properties for the two uppermost saturated hydrogeologic units (i.e., HSU-1 and HSU-2), and to determine distributions of contaminants of concern in these units. Activities undertaken to accomplish these objectives include well installation, geophysical logging, well development, ground-water sampling, slug testing, Westbay ground-water monitoring system installation, continuous water-level monitoring, Hydropunch installation, and surveying. Ground-water samples were collected from 61 Hydropunch locations. Analytical results from these locations and the wells indicate high chloroform concentrations trending from west/southwest to east/northeast in the lower portion of HSU-1 and in the upper and middle portions of HSU-2. The chloroform appears to originate near Landfill 2. Tritium was not found above the MCL in any of the well or Hydropunch samples. Hexavalent chromium was found at four locations with concentrations above the MCL in HSU-1 and at one location in HSU-2. One well in HSU-1 had a total chromium concentration above the MCL. Nitrate-nitrogen above the MCL was found at several Hydropunch locations in both HSU-1 and HSU-2.

    We studied the mechanism of radiation-induced apoptosis, the factors involved signaling, and the establishment of radiation-resistant cell lines in this study. During the TGF beta-stimulated epithelial mesenchymal transition(EMT), actin rearrangement occurred first and fibronectin matrix assembly followed. These two events were considered independent since cytochalasin-D did not inhibit TGF stimulated matrix assembly and fibronectin supplementation did not induce EMT. During EMT, alpha 5 beta 1 integrin and alpha v integrin have increased but MMP activation was not accompanied, which suggest that induction of extracellular matrix and activation of integrins may be main contributor for the EMT. Serum depriving induced apoptosis of HUVECs was prevented by vascular endothelial growth factor(VEGF) and PMA. The apoptosis prevention by VEGF and PMA were conformed by DNA fragmentation assay. The p53 expression level was down regulated by VEGF and PMA compared with serum deprived HUVECs. However, VEGF and PMA induces c-Myc expression level on these cells. We made the 5 radiation-resistant clones from breast, lung and cervical cancer cells. More than 70%, 100% and 50% increased resistance was detected in breast cancer cells, lung cancer cells, and cervical cells, respectively. We carried out differential display-PCR to clone the radiation-resistant genes. 9 out of 10 genes were analyzed their sequence.

Using the deployment of the federal funding with industrial participation as a performance criterion, over the course of the program, the copsonsors contributed more dollars than the federal funds. As stated earlier, a little more than half of the funding for the Program was derived from industrial partners. The industrial partners also enthusiastically supported the research and development activities with cash contribution of $4,710,372.67, nearly 65% of the required cost share. Work on all of the tasks proposed under the Cooperative Agreement has been completed. This report summarizes and highlights the results from the Program. Under the Cooperative Agreement Program, energy-related tasks emphasized petroleum processing, upgrading and characterization, coal and biomass beneficiation and upgrading, coal combustion systems development including oxy-combustion, emissions monitoring and abatement, coal gasification technologies including gas clean-up and conditioning, hydrogen and liquid fuels production, and the development of technologies for the utilization of renewable energy resources. Environmental-related activities emphasized cleaning contaminated soils using microbial fuel cells, development of processes and sorbents for emissions reduction and recovery of water from power plant flue gas, and biological carbon capture and reuse. Technology enhancement activities included resource characterization studies, development of improved methods, monitors and sensors. In general the goals of the tasks proposed were to enhance competitiveness of U.S. technology, increase production of domestic resources, and reduce environmental impacts associated with energy production and utilization. Technologies being brought to commercialization as a result of the funds provided by the Cooperative Agreement contribute to the overall goals of the USDOE and the nation.

    Full Text Available ABSTRACT Biodiversity decline has been the focus of discussions in the last decade, especially on the amphibian species decline. After a scientometric analysis using international databases, we found that the number of peer-reviewed articles considering education practices related to the theme increased along with the number of ecological researches. However, the increase in ecological researches is much higher than the increase in publications of education practices. Studies suggest that conservation attitudes are important and that education practices are an important tool for improving human perceptions on this subject. In this sense, increase the publication of projects and programs results related to local education practices in international journals could help the dissemination of efficient methods for conservation, as well as facilitating access to information internationally, since species decline, especially for amphibians, is a global concern. Then, we suggest that educational practices, at least when related to conservation, should follow a more standardized protocol, and be published in international journals, as the efficiency of such practices should be evaluated and methods once published could help other nations to improve their ecological literacy.

    The Comae Berenicids have been considered as a winter shower but lower meteor activities continue the whole year round in this region. It might be called the meteors of Coma Sororum Medusae (CSM) instead of Comae Berenicids (COM). The CSM radiant passes the zenith twice in lower latitudes of the northern hemisphere and CSM activities vary with the altitude of the radiant. December Leonis Minorids (DLM) and September varepsilon-Perseids (SPE) are distinct from the CSM background meteors, but July Pegasids (JPE), delta-Aurigids (DAU) and nu-Aurigids (NAU) are buried in this complex. The conglomeration of DLM, COM and JCO (January Comae Berenicids) has caused confusion in meteor observations as to whether they are three distinct sources or should be considered as one. A simple model of meteor stream structure shows the clear profile of their activities. Although their radiant drifts are overlapping, they might have different parent objects.

    Full Text Available Public relations give opportunity to the organization to present its image and personality to its own “public”- users, supporters, sponsors, donors, local community and other public. It is about transferring the message to the public, but that is a two-way street. You must communicate with your public, but at the same time you must give opportunity to the public to communicate easier with you. The real public relations include dialog – you should listen to the others, to see things through their perspective. This elaborate is made with the purpose to be useful for every organization, not for the sensa-tional promotion of its achievements, but to become more critical towards its work. Seeing the organization in the way that the other see it, you can become better and sure that you are giving to your users the best service possible.

    Full Text Available In 2017, the 19th World Swimming Championship will be organized in Hungary. Up to now, many people have already been working with swimmers to achieve good results. However, in the next period they must work even harder to ensure that the national swimmers of a country as small as Hungary can achieve the outstanding results of their predecessors. Since high-level competitions in swimming have become more intense, innovations including scientific studies are needed during preparation for the event. The purpose of this paper is to present the major results of an independent study carried out by the authors about the relative age of the best Hungarian swimmers with the aim of contributing to their preparation. The research population consisted of selected age groups of swimmers registered by the Hungarian Swimming Association (N=400. The method for data collection was an analysis of documents. To evaluate the data, the Chi-square and Kruskal-Wallis tests were used. The results are presented according to the period of the competitor’s date of birth, gender, and age group. The results confirm only partly the hypothesis that people born in the first quarters of the year play a dominant role in Hungarian national swimming teams. In the conclusion, the authors recommend further research on relative age in swimming and in other sports.

    2004-08-01

    This paper reports findings from a postal questionnaire survey and in-depth interviews with UK funders of health-related research that explored whether, why and how they promote consumer involvement in research projects. Many UK funders of health-related research are adopting a policy of promoting consumer involvement in research projects. Telephone interviews revealed they have several reasons for doing so, and that they vary in the ways they encourage and support researchers to involve consumers. For some, descriptions of consumer involvement in a research proposal are important for project funding decisions. They recognized a need for flexibility when assessing consumer involvement in different contexts. We suggest that funders should continue to work to clarify what they consider to be the parameters of acceptability in terms of consumer involvement and ensure that 'flexible' criteria are fairly applied. Researchers should be aware of particular funders' views when applying for project funding.

    In 2010-2015 dozen of unconventional hydrocarbons wells were drilled in Poland. These earliest cases of new industrial activity in Europe were carefully observed and monitored both by the society and scientific community. One of the biggest and most comprehensive researches on environmental impact posed by the activity was the one conducted by a scientific consortium led by the PGI-NRI. The outcomes of this study are still relevant as a basic data for environmental impact assessment and ought to be more widely used for analysis and comparisons as they documented real case studies involving local factors and conditions. With this presentation, issues related to soil will be discussed, including sub-soil compaction (due to overburden from infrastructure and topsoil temporary storage heaps) as well as contamination by accidental spills of chemicals and technological fluids. Both chemical and agricultural properties of soils have been tested. Within the study, contents of methane and others light hydrocarbons in soil gas were considered as possible indicators of stray gases migration towards the land surface from deeper formations. Thus, such gases survey was conducted with concentrations as well as isotopic characteristics analysis. According to the results a peculiar and unexpected phenomenon of increased methane concentration under site protective impermeable coverage were observed. It is supposed to be caused by a mix of local geological conditions and land-use pattern. Based on real study results a need for baseline conditions establishment as well as continuous soil properties monitoring is needed in order to protect the soil itself as well as to have a tool for unwanted substances migration indicator. For both purposes proper sampling strategy recommendation need to be elaborated.

    Full Text Available Probably, obesity can be considered as the most common metabolic disorder. In other words, the control of metabolism is disrupted in this condition. The most important metabolic control is performed by hormones. Today, adipose tissue is considered as an active tissue in secretion of hormones. In obesity, in addition to adipose tissue hormones, effective neuropeptides on appetite are interfered. There are 4 main approaches in the management and treatment of obesity including nutrition and diet therapy, physical activity, medical and surgical approaches. The specialists and obese patients prefer the first and second approaches. Physical activity helps to control and treat this disorder by influencing on obesity-related hormones. The main obesity-related hormones are ghrelin, agouti, obestatin, leptin, adiponectin, nesfatin, visfatin, tumor necrosis factor, interleukin-6, and resistin. In this review, the effect of physical activity on 10 major obesity-related hormones has been discussed.

    2017-03-01

    A sedentary lifestyle and lack of physical activity are well-established risk factors for chronic disease and adverse health outcomes. Thus, there is enormous interest in measuring physical activity in biomedical research. Many consumer physical activity monitors, including Basis Health Tracker, BodyMedia Fit, DirectLife, Fitbit Flex, Fitbit One, Fitbit Zip, Garmin Vivofit, Jawbone UP, MisFit Shine, Nike FuelBand, Polar Loop, Withings Pulse O2, and others have accuracies similar to that of research-grade physical activity monitors for measuring steps. This review focuses on the unprecedented opportunities that consumer physical activity monitors offer for human physiology and pathophysiology research because of their ability to measure activity continuously under real-life conditions and because they are already widely used by consumers. We examine current and potential uses of consumer physical activity monitors as a measuring or monitoring device, or as an intervention in strategies to change behavior and predict health outcomes. The accuracy, reliability, reproducibility, and validity of consumer physical activity monitors are reviewed, as are limitations and challenges associated with using these devices in research. Other topics covered include how smartphone apps and platforms, such as the Apple ResearchKit, can be used in conjunction with consumer physical activity monitors for research. Lastly, the future of consumer physical activity monitors and related technology is considered: pattern recognition, integration of sleep monitors, and other biosensors in combination with new forms of information processing.

    Carson, Lloyd

    2014-07-01

    Zoos have increasingly sought to justify their existence by reference to a scientific role particularly in the domains of animal welfare and conservation. Given recent initiatives by the UK government to foster public engagement with science, it is timely to investigate public attitudes towards primary research activity by zoos. This study reports the views of 83 visitors to Edinburgh Zoo. Within certain items in a structured interview noun terms denoting research activity were manipulated ("research" versus "studies") as was their qualification (adjective "scientific" present or absent before the noun term). "Research" was associated with a restricted and negative perception of investigatory activity. This effect was intensified when the noun term was preceded by "scientific". It is concluded that there is a continuing need to challenge public perceptions, particularly of the phrase "scientific research"; that in the meantime zoos should perhaps exercise caution when using it in relation to their activities.

    2015-10-01

    Asymmetric frontal cortical activity may be one key to the process linking social exclusion to jealous feelings. The current research examined the causal role of asymmetric frontal brain activity in modulating jealousy in response to social exclusion. Transcranial direct-current stimulation (tDCS) over the frontal cortex to manipulate asymmetric frontal cortical activity was combined with a modified version of the Cyberball paradigm designed to induce jealousy. After receiving 15 min of tDCS, participants were excluded by a desired partner and reported how jealous they felt. Among individuals who were excluded, tDCS to increase relative left frontal cortical activity caused greater levels of self-reported jealousy compared to tDCS to increase relative right frontal cortical activity or sham stimulation. Limitations concerning the specificity of this effect and implications for the role of the asymmetric prefrontal cortical activity in motivated behaviors are discussed.

    The primary purpose of this study was to investigate the association between burnout and neural activation during working memory processing in patients with stress-related exhaustion. Additionally, we investigated the neural effects of cognitive training as part of stress rehabilitation. Fifty......, burnout level was positively associated with neural activation in the rostral prefrontal cortex, the posterior parietal cortex and the striatum, primarily in the 2-back condition. Following stress rehabilitation, the striatal activity decreased as a function of improved levels of burnout. No significant...... association between burnout level and working memory performance was found, however, our findings indicate that frontostriatal neural responses related to working memory were modulated by burnout severity. We suggest that patients with high levels of burnout need to recruit additional cognitive resources...

    The research on iodine, as on other important fission products which would be released during a severe accident, carried out directly or organized by the European Commission stems from the Euratom Treaty, namely from Chapter III of the treaty which deals with the protection of the health of the population against radiations and from Chapter I which deals with research. In this paper we do not consider the Commission radiological protection programme: we limit ourselves to the presentation of the research carried out on Iodine as part of the most recent source term studies within the framework Programmes as are called the research programme of the European Commission, usually valid for a 4 year periods. The research activities are carried out by the European Commission either directly through the Joint Research Centres (JRC) or indirectly through collaboration with research organizations of Member States. Concerning the iodine research carried out as Direct Action in the Joint Research Centres, are mentioned here the most relevant activities carried out in this field at the JRC of Ispra and Karlsruhe (TUI). As Indirect Action, we present here the results of some studies allocated by the European Commission to experts of research organizations of Member Countries, followed by a short description of the main results achieved by the Reinforced Concerted Action, within the III Framework Programme (1992-1995). At the end of the paper are described the research on iodine being carried out or proposed within the IV Framework Programme (1995-1998). Mention is also done of the Commission participation, relevant in terms of financial and human efforts, to the PHEBUS FP Project. (author) refs.

  12. Business model in research-development activity

    2016-09-01

    Full Text Available The partners and allies of business practice in the processes of modernization of the economy are scientific-research institutions, such as scientific institutes, research-development units and universities. A market on which companies can look for the solutions they need and scientific-research institutions can look for inspiration, partners and capital is being formed. The market provides conditions for operation, development and implementation of developed solutions. Taking into consideration the complexity of market, technical, legal, financial, or intellectual property protection issues, research-development units are more and more frequently unable to function efficiently without a clear and unequivocal definition of goals, methods and conditions of activity. Their market offer has to take into consideration not just scientific-research, or methodological aspects. Taking into consideration continuously growing demands of the clients and pressure of the competition, scientific-research institutions have to pay attention also to market, information, personnel, or financial aspects typical of strictly commercial ventures. What may support a comprehensive preparation and implementation of scientific-research activities under market conditions are tools successfully used in trade and economy, such as business models. These issues are the basis of deliberations contained in this work.

    Ingram, Katrin; Ellis, William; Keiser, Jennifer

    2012-06-01

    Interesting antischistosomal properties have been documented for the antimalarial mefloquine, a 4-quinolinemethanol. We evaluated the antischistosomal activities of nine mefloquine-related compounds belonging to the 4-pyridinemethanols, 9-phenanthrenmethanols, and 4-quinolinemethanols. Eight compounds revealed high activities against Schistosoma mansoni in vitro, with two drugs (the 4-quinolinemethanols WR7573 and WR7930) characterized by significantly lower half-maximal inhibitory concentrations (IC(50)s) (2.7 and 3.5 μM, respectively) compared to mefloquine (11.4 μM). Mefloquine and WR7930 showed significantly decreased IC(50)s when incubated in the presence of hemoglobin. High worm burden reductions (WBR) were obtained with enpiroline (WBR, 82.7%; dosage, 200 mg/kg of body weight) and its threo isomers (+)-threo (WBR, 100%) and (-)-threo (WBR, 89%) and with WR7930 (WBR, 87%; dosage, 100 mg/kg) against adult S. mansoni in mice. Furthermore, excellent in vitro and in vivo antischistosomal activity was observed for two WR7930-related structures (WR29252 and WR7524). In addition, mefloquine (WBR, 81%), enpiroline (WBR, 77%), and WR7930 (WBR, 100%) showed high activities against S. haematobium harbored in mice following single oral doses of 200 mg/kg. These results provide a deeper insight into the structural features of the arylmethanols that rule antischistosomal activity. Further studies should be launched with enpiroline and WR7930.

    1998-09-01

    Although the consequences of physical activity have been carefully documented, less is known about its correlates, particularly among children and youth. Based on a representative national survey of 1131 Icelandic adolescents, the study examined various physical, psychological, social and demographic factors related to physical activity. Male sex, significant others' involvement in physical activity (father, friend and older brother), sociability, perceived importance of sport and of health improvement and satisfaction with mandatory gym classes in school, were all related to more involvement, whereas hours of paid work and TV-viewing were related to less. Furthermore, the data suggested that the influence of friend's participation in physical activity depends on his or her emotional significance. Influential others appeared to affect males and females in the same way. The meaning of the results and their implications for future research are discussed.

    As the underutilization of research reactors around the world persists as a primary topic of concern among facility owners and operators, the IAEA responded in 2013 with a broad range of activities to address the planning, execution and improvement of many experimental techniques. The revision of two critical documents for planning and diversifying a facility's portfolio of applications, TECDOC 1234 “The Applications of Research Reactors” and TECDOC 1212 “Strategic Planning for Research Reactors”, is in progress in order to keep this information relevant, corresponding to the dynamism of experimental techniques and research capabilities. Related to the latter TECDOC, the IAEA convened a meeting in 2013 for the expert review of a number of strategic plans submitted by research reactor operators in developing countries. A number of activities focusing on specific applications are either continuing or beginning as well. In neutron activation analysis, a joint round of inter-comparison proficiency testing sponsored by the IAEA Technical Cooperation Department will be completed, and facility progress in measurement accuracy is described. Also, a training workshop in neutron imaging and Coordinated Research Projects in reactor benchmarks, automation of neutron activation analysis and neutron beam techniques for material testing intend to advance these activities as more beneficial services to researchers and other users.

    In this article we analyse whether university-industry relations (UIR) work to inhibit university researchers' scientific productivity. We find that UIR exercise a positive effect on university scientific productivity when they are based on the development of activities with high scientific content, but only up to certain level. Also, we find that researchers that combine research and UIR activities obtain higher funding from competitive public sources than those that only engage in research....

    2015-04-01

    Full Text Available The purpose of the research is development of the new methods of diagnostic the research activities productivity. It is known, that for the evaluation the productivity of a scientist we usually use a well-known index of Hirsch, the introduction of which in 2005 was a significant step forward compared with application of this index as the ratio of the number of references to works of scientist and publications themselves. At the same time even h-index as an indicator is not flawless, the main flaw is weak differential ability: a number of links to the most cited publications of the scientific worker does not matter after reaching a certain threshold. It is necessary to develop a method of estimating the productivity of scientific worker, which preserves dignities of h-index and removes its shortcomings. This will allow evaluating the productivity of research activities more objectively. Methodological bases of the research: a systematic approach (considering the science as a social institution in close connection with the society as a whole, a metasystem approach (considering the results of the scientific activities as a metasystem, i.e. the system with relatively independent components, probabilistic and statistical approach (considering the research activities as the random process, a synergistic approach (considering science like a self-organized system qualimetric approach (considering the productivity of scientific activity as latent variables that reflect a variety of criteria

    2004-01-01

    Activation of sphalerite ZnS, (Zn, Fe)S, (Zn, Cu)S were carried out using the density functional theory (DFT) method. The electronic structures and related properties of three kind of zinc sulfide compounds were investigated. In addition, the relation between electronic structure and flotation behavior was discussed. The results show that, ZnS has a broader band gap than (Zn,Cu)S and (Zn,Fe)S do, and it has low electrochemistry activity to react with flotation collectors to render the surface hydrophobic. When the Zn atom in ZnS is replaced by Cu atom,the band gap will be reduced, and the top valence band will be occupied by Cu 3d orbit, thus it is beneficial to the interaction between mineral surface and collector.

    Motor activity as a diagnostic parameter has become an important feature in many fields of medicine and psychology. The concept of mobility and immobility implies the assumption that mental and behaviour disorders involve abnormal activity that can be measured to characterise the disorder itself, to diagnose its presence and to document the impact of treatment. In sleep research, activity monitoring by wrist actigraphs has proven its usefulness as an efficient method to assess the rest-activity cycle over long time periods and to estimate sleep-related features such as sleep efficiency and total sleep time. But like many other techniques and devices, activity monitoring has some limitations and drawbacks. This paper describes the basic features of wrist actigraphy in measuring nocturnal and daytime motor activity.

    Full Text Available Abstract Introduction The importance of gender in understanding health practices and illness experiences is increasingly recognized, and key to this work is a better understanding of the application of gender relations. The influence of masculinities and femininities, and the interplay within and between them manifests within relations and interactions among couples, family members and peers to influence health behaviours and outcomes. Methods To explore how conceptualizations of gender relations have been integrated in health research a scoping review of the existing literature was conducted. The key terms gender relations, gender interactions, relations gender, partner communication, femininities and masculinities were used to search online databases. Results Through analysis of this literature we identified two main ways gender relations were integrated in health research: a as emergent findings; and b as a basis for research design. In the latter, gender relations are included in conceptual frameworks, guide data collection and are used to direct data analysis. Conclusions Current uses of gender relations are typically positioned within intimate heterosexual couples whereby single narratives (i.e., either men or women are used to explore the influence and/or impact of intimate partner gender relations on health and illness issues. Recommendations for advancing gender relations and health research are discussed. This research has the potential to reduce gender inequities in health.

  13. Electromechanically active polymer transducers: research in Europe

    2013-10-01

    Smart materials and structures based on electromechanically active polymers (EAPs) represent a fast growing and stimulating field of research and development. EAPs are materials capable of changing dimensions and/or shape in response to suitable electrical stimuli. They are commonly classified in two major families: ionic EAPs (activated by an electrically induced transport of ions and/or solvent) and electronic EAPs (activated by electrostatic forces). These polymers show interesting properties, such as sizable active strains and/or stresses in response to electrical driving, high mechanical flexibility, low density, structural simplicity, ease of processing and scalability, no acoustic noise and, in most cases, low costs. Since many of these characteristics can also describe natural muscle tissues from an engineering standpoint, it is not surprising that EAP transducers are sometimes also referred to as 'muscle-like smart materials' or 'artificial muscles'. They are used not only to generate motion, but also to sense or harvest energy from it. In particular, EAP electromechanical transducers are studied for applications that can benefit from their 'biomimetic' characteristics, with possible usages from the micro- to the macro-scale, spanning several disciplines, such as mechatronics, robotics, automation, biotechnology and biomedical engineering, haptics, fluidics, optics and acoustics. Currently, the EAP field is just undergoing its initial transition from academic research into commercialization, with companies starting to invest in this technology and the first products appearing on the market. This focus issue is intentionally aimed at gathering contributions from the most influential European groups working in the EAP field. In fact, today Europe hosts the broadest EAP community worldwide. The rapid expansion of the EAP field in Europe, where it historically has strong roots, has stimulated the creation of the 'European Scientific Network for Artificial

    Directory of Open Access Journals (Sweden)

    Ruth Morrow

    2012-11-01

    Full Text Available Environmental activism has a long history in protest, addressing issues of degradation and segregation that threaten existing ecologies, social and built fabrics. Environmental activism is traditionally understood as a reaction, chiefly by groups of people, against a perceived external threat. In the 60’s and 70’s, an activist stance began to emerge in the work of some artists and architects, who used creative methods such as performances, happenings, temporary spatial interventions etc to convey their political/aesthetic messages. Some of this work engaged directly with communities but predominantly it was the production of one individual working ‘outside’ society. However such actions demonstrated not only the power of the visual in conveying a political message but also the potential of conceptual creative approaches to reveal alternative values and hidden potentials. This marked a shift from activism as protestation towards an activism of reconceptualisation. Recently, activist groups have developed a more politically informed process. Whilst their ‘tools’ may resemble work from the 60’s and 70’s, their methodologies are nontraditional, ’rhizomatic’, pedagogical and fluid; working alongside, rather than against, the established power and funding structures. Such creative processes build new, often unexpected, stakeholder networks; offer neutral spaces in which contentious issues can be faced; and create better understanding of values and identities. They can also lead to permanent improvements and development in the physical fabric. This paper will discuss a pedagogical example of activism in architectural education. The event (www.fourdaysontheoutside.com is in its fifth year of existence and as such has revealed a value and impulse beyond its learning and teaching value. The paper will discuss how the event contributes to the university’s outreach programme and how its structure acts as a seedbed for potential

  16. Simulating Activities: Relating Motives, Deliberation and Attentive Coordination

    Clancey, William J.; Clancy, Daniel (Technical Monitor)

    2002-01-01

    Activities are located behaviors, taking time, conceived as socially meaningful, and usually involving interaction with tools and the environment. In modeling human cognition as a form of problem solving (goal-directed search and operator sequencing), cognitive science researchers have not adequately studied "off-task" activities (e.g., waiting), non-intellectual motives (e.g., hunger), sustaining a goal state (e.g., playful interaction), and coupled perceptual-motor dynamics (e.g., following someone). These aspects of human behavior have been considered in bits and pieces in past research, identified as scripts, human factors, behavior settings, ensemble, flow experience, and situated action. More broadly, activity theory provides a comprehensive framework relating motives, goals, and operations. This paper ties these ideas together, using examples from work life in a Canadian High Arctic research station. The emphasis is on simulating human behavior as it naturally occurs, such that "working" is understood as an aspect of living. The result is a synthesis of previously unrelated analytic perspectives and a broader appreciation of the nature of human cognition. Simulating activities in this comprehensive way is useful for understanding work practice, promoting learning, and designing better tools, including human-robot systems.

    2014-02-01

    Nurse researchers engaged in qualitative interviews with patients and spouses in healthcare may often experience being in unforeseen ethical dilemmas. Researchers are guided by the bioethical principles of justice, beneficence, non-maleficence, respect for human rights and respect for autonomy through the entire research process. However, these principles are not sufficient to prepare researchers for unanticipated ethical dilemmas related to qualitative research interviews. We describe and discuss ethically challenging and difficult moments embedded in two cases from our own phenomenological interview studies. We argue that qualitative interviews involve navigation between being guided by bioethics as a researcher, being a therapist/nurse and being a fellow human being or even a friend. The researchers' premises to react to unexpected situations and act in a sound ethical manner must be enhanced, and there is a need for an increased focus on the researchers' ethical preparation and to continually address and discuss cases from their own interviews.

    The application of the infrared imaging using in the brain cognition and the acupuncture is introduced. Acupuncturing a certain point of the healthy experimental cats, observing the responds of the cerebral cortical temperature by using of infrared imaging, and researching the corresponding relation between the acupuncture points with the active sections of the cerebral cortex, so the effect of the acupuncture is obtained. The theory of the refreshment and induce resuscitation pinprick is approved. The method of the "refreshment and induce resuscitation pinprick" can promote the metabolize renovation, improve the living function and increase the healing rate. However, the relations between the points and the cortical functional sections have not the last word still. After removing the skulls on the head, full of the cerebral cortex of a cat are exposed. Observing the infrared imaging and measuring the temperatures of the visual cerebral cortex during the process of acupuncturing the points to judge the activation position. During the process of acupuncture, the trend of the rising temperature on cerebral cortex is primary in terms of the phenomena in the infrared pictures. The cortical hemogram variety is measured in terms of the infrared pictures and the temperature values, so the characteristic curve of the temperature for a corresponding position on the cerebral cortex and the acupuncture point can be obtained. When the acupuncture point is changed, the position where temperature varied on cerebral cortex is different correspondingly. The variety in the cortical functional sections is corresponding to the result of the acupuncture point in terms of the imaging and the temperatures. The experimental results accord with the theoretic model, so they validate the correctness of the "refreshment and induce resuscitation pinprick". According to the experimental results, we know that the variety of a cortical functional section is corresponding to a special acupuncture

    2013-07-01

    This presentation describes the different activities in the research reactor field that are being carried out by INVAP. INVAP is presently involved in the design of three new research reactors in three different countries. The RA-10 is a multipurpose reactor, in Argentina, planned as a replacement for the RA-3 reactor. INVAP was contracted by CNEA for carrying out the preliminary engineering for this reactor, and has recently been contracted by CNEA for the detailed engineering. CNEA groups are strongly involved in the design of this reactor. The RMB is a multipurpose reactor, planned by CNEN from Brazil. CNEN, through REDETEC, has contracted INVAP to carry out the preliminary engineering for this reactor. As the user requirements for RA-10 and RMB are very similar, an agreement was signed between Argentina and Brasil governments to cooperate in these two projects. The agreement included that both reactors would use the OPAL reactor in Australia, design and built by INVAP, as a reference reactor. INVAP has also designed the LPRR reactor for KACST in Saudi Arabia. The LPRR is a 30 kw reactor for educational purposes. KACST initially contracted INVAP for the engineering for this reactor and has recently signed the contract with INVAP for building the reactor. General details of these three reactors will be presented.

In recent years, China has recognized the importance and benefits of the emerging ASON/ASTN techniques. During the period of 2001 and 2002, the national 863 Program of China started the preliminary ASON research projects with the main objectives to build preliminary ASON testbeds, develop control plane protocols and test their performance in the testbeds. During the period of 2003 and 2004, the 863 program started ASTN prototyping equipment projects for more practical applications. Totally 12 ASTN equipments are being developed by three groups led by Chinese venders: ZTE with Beijing University of Posts and Telecommunications (BUPT), Wuhan Research Institute of Posts and Telecommunication (WRI) with Shanghai Jiao Tong University (SJTU), and Huawei Inc. Meanwhile, as the ASTN is maturing, some of the China"s carries are participating in the OIF"s World Interoperability Demonstration, carrying out ASTN test, or deploying ASTN backbone networks. Finally, several ASTN backbone networks being tested or deployed now will be operated by the carries in 2005. The 863 Program will carry out an ASTN field trail in Yangtse River Delta, and finally deploy the 3TNET. 3TNET stands for Tbps transmission, Tbps switching, and Tbps routing, as well as a network integrating the above techniques. A task force under the "863" program is responsible for ASTN equipment specifications and interoperation agreements, technical coordination among all the participants, schedule of the whole project during the project undergoing, and organization of internetworking of all the equipments in the laboratories and field trials.

    The mission of the U.S. Nuclear Regulatory Commission (NRC) is to ensure the safe design, construction, and operation of commercial nuclear power plants and other facilities in the U.S.A. One of the main roles that the Office of Nuclear Regulatory Research (RES) plays in achieving the NRC mission is to plan, recommend, and implement research programs that address safety and technical issues deemed important by the NRC. The results of the research activities provide the bases for developing NRC positions or decisions on these issues. Also, RES performs confirmatory research for developing the basis to evaluate industry responses and positions on various regulatory requirements. This presentation summarizes some recent RES supported research activities that have addressed safety and technical issues related to valves and pumps. These activities include the efforts on determining valve and motor-operator responses under dynamic loads and pressure locking events, evaluation of monitoring equipment, and methods for detecting and trending aging of check valves and pumps. The role that RES is expected to play in future years to fulfill the NRC mission is also discussed.

    A multidisciplinary team of IEQ and energy researchers has defined a program of priority energy-related IEQ research. This paper describes the methods employed to develop the agenda, and 35 high priority research and development (R&D) project areas related to four broad goals: (1) identifying IEQ problems and opportunities; (2) developing and evaluating energy-efficient technologies for improving IEQ; (3) developing and evaluating energy-efficient practices for improving IEQ; and (4) encouraging or assisting the implementation of technologies or practices for improving IEQ. The identified R&D priorities reflect a strong need to benchmark IEQ conditions in small commercial buildings, schools, and residences. The R&D priorities also reflect the need to better understand how people are affected by IEQ conditions and by the related building characteristics and operation and maintenance practices. The associated research findings will provide a clearer definition of acceptable IEQ that is required to guide the development of technologies, practices, standards, and guidelines. Quantifying the effects of building characteristics and practices on IEQ conditions, in order to provide the basis for development of energy efficient and effective IEQ control measures, was also considered a priority. The development or advancement in a broad range of IEQ tools, technologies, and practices are also a major component of the priority research agenda. Consistent with the focus on ''energy-related'' research priorities, building ventilation and heating, ventilating and air conditioning (HVAC) systems and processes are very prominent in the agenda. Research related to moisture and microbiological problems, particularly within hot and humid climates, is also prominent within the agenda. The agenda tends to emphasize research on residences, small commercial buildings, and schools because these types of buildings have been underrepresented in prior research. Most of

    Introduction The increase in emerging human infectious diseases that have a zoonotic origin and the increasing resistance of microorganisms to antimicrobial drugs have shown the need for collaborations between the human, animal and environmental health sectors. The One Health concept increasingly receives recognition from policy makers and researchers all over the world. This overview compiled research and education activities in the area of One Health in Western Europe (Austria, Belgium, France, Germany, Italy, Iceland, Ireland, Liechtenstein, Luxembourg, Monaco, the Netherlands, Portugal, Scandinavia, Spain, Switzerland, and the United Kingdom (UK), with a focus on infectious diseases. It can serve as a starting point for future initiatives and collaborations. Material and methods A literature search for ‘One Health’ was performed using National Center for Biotechnology Information and Google. Moreover, information from global and European policy documents was collected and a questionnaire was designed to gather current One Health research and training activities in Western Europe. Results This overview shows that there is considerable recognition for One Health in Europe, although most educational initiatives are recent. In Europe, the One Health approach is currently mainly advocated in relation to antimicrobial resistance (AMR). Many countries have incorporated the One Health approach in their policy to fight AMR, and funding possibilities for AMR research increased significantly. The number of national and international multidisciplinary research networks in the area of zoonotic diseases and One Health is increasing. Discussion Although One Health has gained recognition in Europe, often a One Health approach to research and education in the area of zoonotic diseases and AMR is not implemented.

    2012-01-01

    To provide a comprehensive overview of the many research approaches related to phenomenology and their philosophical underpinnings. Phenomenological research approaches are varied and often difficult to apply appropriately. Some researchers persist in labelling their studies as examples of Heideggerian or Husserlian phenomenology without fully understanding the implications of the underpinning philosophical assumptions. Methodological sources related to phenomenology as a philosophy and phenomenology as a research approach are used to illustrate the range of phenomenological methods and their philosophical underpinnings. The origins of phenomenology are the writings of Husserl and the advancement of his thoughts by Merleau-Ponty, Heidegger, Gadamer and Ricoeur. The importance of fully understanding a methodology and its philosophical underpinnings before using it, or claiming to use it, is emphasised. In addition, the variety of phenomenological research approaches that have evolved over the past 50 years are explored and placed in the context of their philosophical underpinnings. There is no single way to conduct a phenomenological study. There are many approaches from which researchers can choose. This has resulted in a range of labels and often in different descriptions for the same approach. It is essential that researchers planning to use phenomenology are familiar with the many approaches available. This knowledge will help researchers choose the approaches that best suit the aims of their studies.

    2015-04-01

    There are numerous national efforts to determine and develop research priorities of medical education in Saudi Arabia. These priorities were first proposed in 2010 by "Dr Al-Khuli's Chair for Developing Medical Education in Saudi Arabia". The proposed priority domains were: curriculum, students, faculty, and quality assurance and accreditation. To investigate publications in medical education at the national and international levels in areas relating to these proposed priorities. Electronic search within PubMed database for papers relating to each domain of priority was conducted at national and international levels in the last three years, using the same keywords as the priority domains, but only confined to undergraduate medical education. Out of 3145 articles retrieved when searching with keyword as broad as "undergraduate medical curriculum" only 81 articles worldwide and 3 articles from Saudi Arabia were dealing with curriculum related issues as a whole. Further search on the sub-domains "effective strategies to manage undergraduate curriculum" and "undergraduate medical education models", resulted in the retrieval of few articles worldwide and none from Saudi Arabia. At the national level, there were 63 publications from Saudi Arabia that were either course (topic)-specific or could not be classified under the four domains specified by Dr Al-Khuli's Chair. Research activities in medical education in Saudi Arabia in the last 3 years showed diversity and lack of focus in the research priorities. Efforts of academic and research centers should continue to monitor and encourage these activities toward achieving the recommended priorities.

    In this presentation we introduce Earth science related activities of the Big Data Interest Group (BDIG) in Research Data Alliance (RDA). "RDA is an international organization focused on the development of infrastructure and community activities that reduce barriers to data sharing and exchange, and the acceleration of data driven innovation worldwide." The participation of researchers in RDA is voluntary. As the name implies, an Interest Group is a collection of participants sharing the same interest. The BDIG seeks to address community needs on all things having to do with Big Data. The ultimate goal of RDA Big Data Interest Group is to produce a set of recommendation documents to advise diverse research communities with respect to: • How to select an appropriate Big Data solution for a particular science application to realize optimal value? and • What are the best practices in dealing with various data and computing issues associated with such a solution? The primary means to reaching such recommendations is through the establishment and work of Working Groups, each of which focuses on a specific issue. Although BDIG is not specific to Earth science, its recent activities revolve mostly around it. We introduce some of these activities that are designed to advance our knowledge and to characterize Big Data in Earth science.

    2017-04-01

    Scientific communities are building platforms where the usage of data-intensive workflows is crucial to conduct their research campaigns. However managing and effectively support the understanding of the 'live' processes, fostering computational steering, sharing and re-use of data and methods, present several bottlenecks. These are often caused by the poor level of documentation on the methods and the data and how users interact with it. This work wants to explore how in such systems, flexibility in the management of the provenance and its adaptation to the different users and application contexts can lead to new opportunities for its exploitation, improving productivity. In particular, this work illustrates a conceptual and technical framework enabling tunable and actionable provenance in data-intensive workflow systems in support of reproducible science. It introduces the concept of Agile data-intensive systems to define the characteristic of our target platform. It shows a novel approach to the integration of provenance mechanisms, offering flexibility in the scale and in the precision of the provenance data collected, ensuring its relevance to the domain of the data-intensive task, fostering its rapid exploitation. The contributions address aspects of the scale of the provenance records, their usability and active role in the research life-cycle. We will discuss the use of dynamically generated provenance types as the approach for the integration of provenance mechanisms into a data-intensive workflow system. Enabling provenance can be transparent to the workflow user and developer, as well as fully controllable and customisable, depending from their expertise and the application's reproducibility, monitoring and validation requirements. The API that allows the realisation and adoption of a provenance type is presented, especially for what concerns the support of provenance profiling, contextualisation and precision. An actionable approach to provenance

    Full Text Available It is recognized at home and abroad that Cordyceps militaris is a fungus that can be edible and used for medicinal application, and also a common cordyceps taishanensis that is widely distributed and with very high medicinal value in China. Active Cordyceps militaris polypeptide has shown several highlights in its absorption mechanism, such as directly absorbed without the need for digestion, and absorbed quickly and completely, and more and more international researchers are attaching great importance to it. Physiological and pharmacological activities of Cordyceps militaris polypeptide are mainly to activate related enzyme systems, promote intermediary metabolisms or control the DNA transcription and translation, simultaneously activate the reticuloendothelial system and macrophage, promote the transformation of lymphocytes, and as a nonspecific immune enhancer and regulator, activate the immune competent cells, especially lymphocytes, lymphokines, mononuclear macrophage system and NK cells, thereby attacking the target cells to play an antitumor role, and also exerting its anti-aging, anticoagulant, hypolipidemic to enhance the immunity, improve the liver function and delay the aging. In this paper, the immunity improvement, anticancer, antioxidation and antimicrobial activities of active polypeptides from Cordyceps militaris are reviewed, in order to provide a solid theoretical help for the further development and application of active polypeptides of Cordyceps militaris.

    Both cognitive and educational psychology literature strive to investigate human category and concept learning. However, both literatures focus on different phenomena and often use different methodologies. We identify and discuss commonalities and differences between the literatures. This literature comparison reveals that research on relational category learning offers a promising avenue to integration. We suggest that this integration would be especially beneficial to advance our understanding of conceptual change essentially, how complex scientific concepts and categories are acquired and developed in educational contexts elaborating or correcting students' prior conceptions. Furthermore, the focus on relational categories allows us to provide an integrative discussion on how recent lines of research on analogy, memory and category learning, and knowledge restructuring relate to and can inform education. In general, this article advocates the complementary nature of cognitive and educational psychology and identifies viable, and potentially synergistic paths for future research.

    Peer relations are central to adolescent life and, therefore, are crucial to understanding adolescents' engagement in various behaviors. In recent years, public health research has increasingly devoted attention to the implications of peer relations for the kinds of adolescent behaviors that have a direct impact on health. This article advocates for a continuation of this trend. With this aim, we highlight key themes in the rich literature on the general developmental significance of adolescent-peer relations, provide an overview of how these themes have been incorporated into public health research and practice, and suggest future avenues for peer-focused public health research that can inform adolescent health promotion in the United States.

  17. Fertility-related research needs among women at the margins.

    2015-05-01

    Fertility-related research encompasses fertility intentions, preconception care, research amongst pregnant women, and post-partum outcomes of mothers and children. However, some women remain under-represented within this domain of study. Women frequently missing within fertility-related research include those who are already the most vulnerable to health disparities, including female sex workers, lesbian, gay, bisexual, and transgender women, women living with HIV, and women who use drugs. Yet characterization of the needs of these women is important, given their unique fertility-related concerns, including risks and barriers to care emanating from social stigmas and discrimination. This synthesis provides an overview of fertility-related evidence, highlighting where there are clear research gaps among marginalized women and the potential implications of these data shortfalls. Overall, research among marginalized women to date has addressed pregnancy prevention and in some cases fertility intentions, but the majority of studies have focused on post-conception pregnancy safety and the well-being of the child. However, among female sex workers specifically, data on pregnancy safety and the well-being of the child are largely unavailable. Within each marginalized group, preconception care and effectiveness of conception methods are consistently understudied. Ultimately, the absence of epidemiologic, clinical and programmatic evidence limits the availability and quality of reproductive health services for all women and prevents social action to address these gaps.

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

    Directory of Open Access Journals (Sweden)

    Johnson Joy L

    2010-10-01

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

  19. Encouraging entrepreneurship in university labs: Research activities, research outputs, and early doctorate careers

    2017-01-01

    This paper investigates how the encouragement of entrepreneurship within university research labs relates with research activities, research outputs, and early doctorate careers. Utilizing a panel survey of 6,840 science & engineering doctoral students at 39 R1 research universities, this study shows that entrepreneurship is widely encouraged across university research labs, ranging from 54% in biomedical engineering to 18% in particle physics, while only a small share of labs openly discourage entrepreneurship, from approximately 3% in engineering to approximately 12% in the life sciences. Within fields, there is no difference between labs that encourage entrepreneurship and those that do not with respect to basic research activity and the number of publications. At the same time, labs that encourage entrepreneurship are significantly more likely to report invention disclosures, particularly in engineering where such labs are 41% more likely to disclose inventions. With respect to career pathways, PhDs students in labs that encourage entrepreneurship do not differ from other PhDs in their interest in academic careers, but they are 87% more likely to be interested in careers in entrepreneurship and 44% more likely to work in a startup after graduation. These results persist even when accounting for individuals’ pre-PhD interest in entrepreneurship and the encouragement of other non-academic industry careers. PMID:28178270

    Main sequence stars with masses below approximately 0.35 solar masses are fully-convective, and are expected to have a different type of magnetic dynamo than solar-type stars. Observationally, the dynamo mechanism can be probed through the relationship between rotation and magnetic activity, and the evolution of these properties. Though M dwarfs are the most common type of star in the galaxy, a lack of observational constraints at ages beyond 1 Gyr has hampered studies of the rotation-activity relation. To address this, we have made new measurements of rotation and magnetic activity in nearby, field-age M dwarfs. Combining our 386 rotation period measurements and 247 new optical spectra with data from the literature, we are able to probe the rotation-activity in M dwarfs with masses from 0.1 to 0.6 solar masses. We observe a threshold in the mass--period plane that separates active and inactive M dwarfs. The threshold coincides with the fast-period edge of the slowly rotating population, at approximately the rotation period at which an era of rapid rotational evolution appears to cease. We confirm that the activity of rapidly rotating M dwarfs maintains a saturated value. We have measured rotation periods as long as 140 days, allowing us to probe the unsaturated regime in detail. Our data show a clear power-law decay in relative H-alpha luminosity as a function Rossby number. We discuss implications for the magnetic dynamo mechanism.We acknowledge funding from the National Science Foundation, the David and Lucile Packard Foundation Fellowship for Science and Engineering, and the John Templeton Foundation.

  4. Creative communication in public relations activities

    Directory of Open Access Journals (Sweden)

    Dalibor Jakus

    2013-12-01

    Full Text Available This article discusses several approaches to new waves of public relations. Emphasis is given to the creative impulse since many public relations professionals are less familiar with it than other forms of communication. Five criteria are suggested for structuring creative communications: 1. learning how to be a good storyteller; 2. visual communication is the content that could increasingly build strong relationships with audiences; 3. the PR practitioner’s challenge is to evaluate what people are discussing and identify the recurring issues in their marketplace; 4. recognizing that local is new global; and 5. predicate that PR is constantly changing. People who work in public relations possess the skill of offering arguments that will convince the people themselves of something. However, these skills can be offered in traditional or creative forms of expression. If we define public relations as the management of an organization’s communication with its public, then we are referring to the traditional dimension of public relations, the basis and ultimate goal of which are to cultivate relationships with the participants of the process in order to obtain support and to build trust and reputation.

  9. Addressing security issues related to virtual institute distributed activities

    Stytz, Martin R.; Banks, Sheila B.

    2008-03-01

    One issue confounding the development and experimentation of distributed modeling and simulation environments is the inability of the project team to identify and collaborate with resources, both human and technical, from outside the United States. This limitation is especially significant within the human behavior representation area where areas such as cultural effects research and joint command team behavior modeling require the participation of various cultural and national representatives. To address this limitation, as well as other human behavior representation research issues, NATO Research and Technology Organization initiated a project to develop a NATO virtual institute that enables more effective and more collaborative research into human behavior representation. However, in building and operating a virtual institute one of the chief concerns must be the cyber security of the institute. Because the institute "exists" in cyberspace, all of its activities are susceptible to cyberattacks, subterfuge, denial of service and all of the vulnerabilities that networked computers must face. In our opinion, for the concept of virtual institutes to be successful and useful, their operations and services must be protected from the threats in the cyber environment. A key to developing the required protection is the development and promulgation of standards for cyber security. In this paper, we discuss the types of cyber standards that are required, how new internet technologies can be exploited and can benefit the promulgation, development, maintenance, and robustness of the standards. This paper is organized as follows. Section One introduces the concept of the virtual institutes, the expected benefits, and the motivation for our research and for research in this area. Section Two presents background material and a discussion of topics related to VIs, uman behavior and cultural modeling, and network-centric warfare. Section Three contains a discussion of the

    The authors describe a research group that supports the needs of investigators seeking data from an electronic medical record system. Since its creation in 1972, the Regenstrief Medical Records System has captured and stored more than 350 million discrete coded observations on two million patients. This repository has become a central data source for prospective and retrospective research. It is accessed by six data analysts--working closely with the institutional review board--who provide investigators with timely and accurate data while protecting patient and provider privacy and confidentiality. From January 1, 1999, to July 31, 2002, data analysts tracked their activities involving 47,559 hours of work predominantly for physicians (54%). While data retrieval (36%) and analysis (25%) were primary activities, data analysts also actively collaborated with researchers. Primary objectives of data provided to investigators were to address disease-specific (35.4%) and drug-related (12.2%) questions, support guideline implementation (13.1%), and probe various aspects of clinical epidemiology (5.7%). Outcomes of these endeavors included 117 grants (including 300,000 US dollars per year salary support for data analysts) and 139 papers in peer-reviewed journals by investigators who rated the support provided by data analysts as extremely valuable.

    The Global Observatory for Physical Activity (GoPA!) was launched in response to the physical inactivity pandemic. The aim of this article is to present current information about surveillance, policy, and research on physical activity (PA) and health worldwide. Information was collected for 217 countries. For 139 of these nations we identified a contact who confirmed information's accuracy and completeness. Associations were calculated among surveillance, policy and research categories. Of the 139 countries, 90.6% reported having completed 1 or more PA survey, but less than one-third had 3 or more. 106 included PA on a national plan, but only one-quarter of these were PA-specific. At least 1 peer reviewed publication was identified for 63.3% of the countries. Positive associations (P < .001) were found between research and policy (ρ = 0.35), research and surveillance (ρ = 0.41), and surveillance and policy (ρ = 0.31). Countries with a standalone plan were more likely to have surveillance. Countries with more research were more likely to have a standalone plan and surveillance. Surveillance, policy, and research indicators were positively correlated, suggesting that action at multiple levels tends to stimulate progress in other areas. Efforts to expand PA-related surveillance, policy, and research in lower income countries are needed.

    To evaluate the research-related coursework and research experiences in doctor of pharmacy programs and compare the findings to those of 2 previous studies. A questionnaire was mailed to 88 colleges and schools of pharmacy in the United States and Puerto Rico. The survey instrument sought information on formal research-related coursework; required and elective research experiences; and perceptions of student-conducted research. Seventy-nine colleges and schools completed the questionnaire for a response rate of 88%. Most colleges (>90%) required students to study/complete courses in biostatistics and drug information/literature evaluation; approximately half required research methods coursework. Twenty-five percent required some form of project and requirements were not influenced by class size. Students could often work in teams to complete projects. Respondents generally thought participation in research had some value for motivated students. This study demonstrates the variability in extent of research-related coursework and research experiences in PharmD programs across the country.

    Grey relational analysis is an important part of the grey systems theory, and it is the basis of the grey clustering analysis, grey decision-making and grey controlling. To research whether grey relational models satisfy the four grey relational theorems, several kinds of grey relational models are commented. Some problems including the properties of normality, pair symmetry and wholeness are discussed. The phenomenon that the lower value of almost each grey relational model is not equal to zero is proved. The contradiction problems between the properties of wholeness and pair symmetry are verified. Finally, several propositions are constructed to explain the above problems.

    Kinkade, D.

    2015-12-01

    Our ability to advance scientific research in order to better understand complex Earth systems, address emerging geoscience problems, and meet societal challenges is increasingly dependent upon the concept of Open Science and Data. Although these terms are relatively new to the world of research, Open Science and Data in this context may be described as transparency in the scientific process. This includes the discoverability, public accessibility and reusability of scientific data, as well as accessibility and transparency of scientific communication (www.openscience.org). Scientists and the US government alike are realizing the critical need for easy discovery and access to multidisciplinary data to advance research in the geosciences. The NSF-supported EarthCube project was created to meet this need. EarthCube is developing a community-driven common cyberinfrastructure for the purpose of accessing, integrating, analyzing, sharing and visualizing all forms of data and related resources through advanced technological and computational capabilities. Engaging the geoscience community in EarthCube's development is crucial to its success, and EarthCube is providing several opportunities for geoscience involvement. This presentation will provide an overview of the activities EarthCube is employing to entrain the community in the development process, from governance development and strategic planning, to technical needs gathering. Particular focus will be given to the collection of science-driven use cases as a means of capturing scientific and technical requirements. Such activities inform the development of key technical and computational components that collectively will form a cyberinfrastructure to meet the research needs of the geoscience community.

  8. The Necessity of Public Relations for Sustainable Mining Activities

    2015-04-01

    This paper reports research about the necessity of image making for sustainable mine developments in the Republic of Korea. One of the big risks in mining activities is mining area residents opposing mine developments and operations. Analysis of the media reports on disputes between mining companies and residents can determine causes of opposing mine developments, dispute process, and influences of disputes on processes of mining projects. To do this, civil complaints from 2009 to 2012 and 24 media reports since 2000 on opposing mining activities are analyzed. And, to analyze difficulties of mining companies, the survey is conducted to target to mining companies. 57 representatives of mining companies are participated in the survey. The result of analysis cited that the major reasons of anti-mining activities are environmental degradation and reduced agricultural productivity. And specifically because of water pollution (50%), crop damages (33%), and mining dust pollution (21%), communities of mining area are against mine developments and operations. However, 25% of residents have experience of the damage caused by mining activities and the remaining 75% of residents opposing mining activities simply have anxiety about mining pollution. In the past, construction-oriented, environment-unfriendly mining projects had lasted. And while mine reclamation had been postponed in abandoned mines, mining area residents had suffered from mining pollution. So, mining area residents are highly influenced by the prejudice that mining activities are harmful to mining area communities. Current mining projects in South Korea, unlike the past mining activity, focus on minimizing environmental damage and contributing to mining area communities financially. But, in many case of disputes between mining companies and mining area residents, the both cannot reach an agreements because of the negative prejudice. Moreover, some communities categorically refuse any mining activity. On the

    This is the sixth in a series of monographs on research design and analysis. The purpose of this article is to describe and discuss several concepts related to the measurement of nutrition-related characteristics and outcomes, including validity, reliability, and diagnostic tests. The article reviews the methodologic issues related to capturing the various aspects of a given nutrition measure's reliability, including test-retest, inter-item, and interobserver or inter-rater reliability. Similarly, it covers content validity, indicators of absolute vs relative validity, and internal vs external validity. With respect to diagnostic assessment, the article summarizes the concepts of sensitivity and specificity. The hope is that dietetics practitioners will be able to both use high-quality measures of nutrition concepts in their research and recognize these measures in research completed by others.

  10. Functional imaging and related techniques: An introduction for rehabilitation researchers

    Bruce Crosson, PhD

    2010-04-01

    Full Text Available Over the past 25 years, techniques to image brain structure and function have offered investigators in the cognitive neurosciences and related fields unprecedented opportunities to study how human brain systems work and are connected. Indeed, the number of peer-reviewed research articles using these techniques has grown at an exponential rate during this period. Inevitably, investigators have become interested in mapping neuroplastic changes that support learning and memory using functional neuroimaging, and concomitantly, rehabilitation researchers have become interested in mapping changes in brain systems responsible for treatment effects during the rehabilitation of patients with stroke, traumatic brain injury, and other brain injury or disease. This new rehabilitation research and development arena is important because a greater understanding of how and why brain systems remap in the service of rehabilitation will lead to the development of better treatments.

    The Computer-Based Procedure (CBP) research effort is a part of the Light-Water Reactor Sustainability (LWRS) Program, which provides the technical foundations for licensing and managing the long-term, safe, and economical operation of current nuclear power plants. One of the primary missions of the LWRS program is to help the U.S. nuclear industry adopt new technologies and engineering solutions that facilitate the continued safe operation of the plants and extension of the current operating licenses. One area that could yield tremendous savings in increased efficiency and safety is in improving procedure use. A CBP provides the opportunity to incorporate context-driven job aids, such as drawings, photos, and just-in-time training. The presentation of information in CBPs can be much more flexible and tailored to the task, actual plant condition, and operation mode. The dynamic presentation of the procedure will guide the user down the path of relevant steps, thus minimizing time spent by the field worker to evaluate plant conditions and decisions related to the applicability of each step. This dynamic presentation of the procedure also minimizes the risk of conducting steps out of order and/or incorrectly assessed applicability of steps. This report provides a summary of the main research activities conducted in the Computer-Based Procedures for Field Workers effort since 2012. The main focus of the report is on the research activities conducted in fiscal year 2016. The activities discussed are the Nuclear Electronic Work Packages – Enterprise Requirements initiative, the development of a design guidance for CBPs (which compiles all insights gained through the years of CBP research), the facilitation of vendor studies at the Idaho National Laboratory (INL) Advanced Test Reactor (ATR), a pilot study for how to enhance the plant design modification work process, the collection of feedback from a field evaluation study at Plant Vogtle, and path forward to

    For the last 25 years, every two to three years the Conferencia Latinoamericana de Geofísica Espacial (COLAGE) is held in one of the Latin American countries for the purpose of promoting scientific exchange among scientists of the region and to encourage continued research that is unique to this area of the world. At the more recent conference, the community realized that many individuals both within and outside Latin America have contributed greatly to the understanding of the space sciences in this area of the world. It was therefore decided to assemble a Special Issue Space and Geophysical Physics related to Latin America, presenting recent results and where submissions would be accepted from the world wide community of scientists involved in research appropriate to Latin America. Because of the large number of submissions, these papers have been printed in two separate issues. The first issue was published in Advances in Space Research, Vol. 57, number 6 and contained 15 papers. This is the second issue and contains 25 additional papers. These papers show the wide variety of research, both theoretical and applied, that is currently being developed or related to space and geophysical sciences in the Sub-Continent.

    2000-12-01

    We present preliminary results from our study in which we use moderate resolution spectroscopy to determine the correlation between the chromospheric activity and age of M dwarf stars in wide binary systems. We have observed ~50 M dwarf stars from our sample with the Apache Point Observatory 3.5-m telescope. We measure the ratio of Hα luminosity to the bolometric luminosity (LHα /Lbol) of the M dwarf---a measure of activity that is proven to correlate well with age. This project is unique in that it will extend the chromospheric activity-age relation of low-mass main sequence stars beyond the ages provided by cluster methods. The ages so determined are also independent of the uncertainties in cluster age determinations. The technique has the potential to improve by at least a factor of two the precision and the range over which ages can currently be determined for main sequence stars. Work on this project is supported by the NASA Graduate Student Researchers Program grant NGT-50290 (N.M.S.).

  16. Analysis of research publications that relate to bioterrorism and risk assessment.

    2013-09-01

    Research relating to bioterrorism and its associated risks is interdisciplinary and is performed with a wide variety of objectives. Although published reports of this research have appeared only in the past decade, there has been a steady increase in their number and a continuous diversification of sources, content, and document types. In this analysis, we explored a large set of published reports, identified from accessible indices using simple search techniques, and tried to rationalize the patterns and connectivity of the research subjects rather than the detailed content. The analysis is based on a connectivity network representation built from author-assigned keywords. Network analysis reveals a strong relationship between research aimed at bioterrorism risks and research identified with public health. Additionally, the network identifies clusters of keywords centered on emergency preparedness and food safety issues. The network structure includes a large amount of meta-information that can be used for assessment and planning of research activity and for framing specific research interests.

    2016-12-06

    As global research investment increases, attention inevitably turns to assessing and measuring the outcomes and impact from research programmes. Research can have many different outcomes such as producing advances in scientific knowledge, building research capacity and, ultimately, health and broader societal benefits. The aim of this study was to test the use of a Delphi methodology as a way of gathering views from malaria research experts on research priorities and eliciting relative valuations of the different types of health research impact. An international Delphi survey of 60 malaria research experts was used to understand views on research outcomes and priorities within malaria and across global health more widely. The study demonstrated the application of the Delphi technique to eliciting views on malaria specific research priorities, wider global health research priorities and the values assigned to different types of research impact. In terms of the most important past research successes, the development of new anti-malarial drugs and insecticide-treated bed nets were rated as the most important. When asked about research priorities for future funding, respondents ranked tackling emerging drug and insecticide resistance the highest. With respect to research impact, the panel valued research that focuses on health and health sector benefits and informing policy and product development. Contributions to scientific knowledge, although highly valued, came lower down the ranking, suggesting that efforts to move research discoveries to health products and services are valued more highly than pure advances in scientific knowledge. Although the Delphi technique has been used to elicit views on research questions in global health this was the first time it has been used to assess how a group of research experts value or rank different types of research impact. The results suggest it is feasible to inject the views of a key stakeholder group into the research

    Public relations activities for all organizations can have an important effect on consumer decision-making when buying goods or services. This study examines the effect that public relations activities can have regarding consumer decisions and choice. To explore exemplify this relationship a questionnaire was given to 971 patients within public, university and private hospitals in Ankara, Turkey. Study results show that public relations activities were a crucial factor in determining consumer hospital choice. The majority of respondents reported that the behaviors and attitude of personnel as public relations activities that support the hospital's reputation within the public were the primary variables in hospital choice. Health care managers can use these findings to further understand how patients make informed choices related to usage of a health care facility and to develop and/or improve public relations activities.

  20. The travel-related carbon dioxide emissions of atmospheric researchers

    Stohl, A.

    2008-11-01

    Most atmospheric scientists agree that greenhouse gas emissions have already caused significant changes to the global climate system and that these changes will accelerate in the near future. At the same time, atmospheric scientists who like other scientists rely on international collaboration and information exchange travel a lot and, thereby, cause substantial emissions of CO2. In this paper, the CO2 emissions of the employees working at an atmospheric research institute (the Norwegian Institute for Air Research, NILU) caused by all types of business travel (conference visits, workshops, field campaigns, instrument maintainance, etc.) were calculated for the years 2005 2007. It is estimated that more than 90% of the emissions were caused by air travel, 3% by ground travel and 5% by hotel usage. The travel-related annual emissions were between 1.9 and 2.4 t CO2 per employee or between 3.9 and 5.5 t CO2 per scientist. For comparison, the total annual per capita CO2 emissions are 4.5 t worldwide, 1.2 t for India, 3.8 t for China, 5.9 t for Sweden and 19.1 t for Norway. The travel-related CO2 emissions of a NILU scientist, occurring in 24 days of a year on average, exceed the global average annual per capita emission. Norway's per-capita CO2 emissions are among the highest in the world, mostly because of the emissions from the oil industry. If the emissions per NILU scientist derived in this paper are taken as representative for the average Norwegian researcher, travel by Norwegian scientists would nevertheless account for a substantial 0.2% of Norway's total CO2 emissions. Since most of the travel-related emissions are due to air travel, water vapor emissions, ozone production and contrail formation further increase the relative importance of NILU's travel in terms of radiative forcing.

    Full Text Available This paper summarizes the findings of an analysis of scientific infrastructure service providers (mainly from Germany but also from other European countries. These service providers are evaluated with regard to their potential services for the management of publication-related research data in the field of social sciences, especially economics. For this purpose we conducted both desk research and an online survey of 46 research data centres (RDCs, library networks and public archives; almost 48% responded to our survey. We find that almost three-quarters of all respondents generally store externally generated research data – which also applies to publication-related data. Almost 75% of all respondents also store and host the code of computation or the syntax of statistical analyses. If self-compiled software components are used to generate research outputs, only 40% of all respondents accept these software components for storing and hosting. Eight out of ten institutions also take specific action to ensure long-term data preservation. With regard to the documentation of stored and hosted research data, almost 70% of respondents claim to use the metadata schema of the Data Documentation Initiative (DDI; Dublin Core is used by 30 percent (multiple answers were permitted. Almost two-thirds also use persistent identifiers to facilitate citation of these datasets. Three in four also support researchers in creating metadata for their data. Application programming interfaces (APIs for uploading or searching datasets currently are not yet implemented by any of the respondents. Least common is the use of semantic technologies like RDF.Concluding, the paper discusses the outcome of our survey in relation to Research Data Centres (RDCs and the roles and responsibilities of publication-related data archives for journals in the fields of social sciences.

  3. Distinguishing between gaming and gambling activities in addiction research.

    Gambling and gaming activities have become increasingly recognised as sharing many common features at a structural and aesthetic level. Both have also been implicated as contributing to harm through excessive involvement. Despite this, relatively little attention has been given to the fundamental characteristics that differentiate these two classes of activity, especially in situations where the boundaries between them may be particularly hard to distinguish. This is evident, for example, in digital games that incorporate free and paid virtual currencies or items, as well as the capacity for wagering. Such overlaps create problems for regulatory classifications, screening, diagnosis and treatment. Is the problem related to the gambling or gaming content? In this paper, we review the principal sources of overlap between the activity classes in terms of several dimensions: interactivity, monetisation, betting and wagering, types of outcomes, structural fidelity, context and centrality of content, and advertising. We argue that gaming is principally defined by its interactivity, skill-based play, and contextual indicators of progression and success. In contrast, gambling is defined by betting and wagering mechanics, predominantly chance-determined outcomes, and monetisation features that involve risk and payout to the player. A checklist measure is provided, with practical examples, to examine activities according to features of design and function, which may inform guidelines for policy makers, researchers and treatment providers. We suggest that, in some instances, using category-based nomenclature (e.g., "gambling-like game") may be too vague or cumbersome to adequately organise our understanding of new gaming/gambling hybrid activities.

The joint venture is actually called "PROBRAL: Precise positioning and height determination by means of GPS: Modeling of errors and transformation into physical heights" and focuses on research and education within the field of satellite geodesy. PROBRAL is funded by the Brazilian academic exchange service CAPES and the German academic exchange service DAAD. The geodetic aim of the research project is to validate and improve the quality of 3d positions derived from observations related to satellite navigation systems like GPS. In order to fulfill this ambitious goal sustainably, research has to be carried out in close cooperation. At the same time, e.g. to guarantee continuous success, a coordinated education has to be ensured. Besides technical education aspects key competences (e.g. language, capacity for teamwork, project management skills) are trained. Within the presentation the lessons which were learned from this project are discussed in detail.

    I.Introduction Reading is one of the cores in English teaching.Reading means getting meaning out of a given text.It's the ability to understand the written words and respond to them in proper ways.Reading is an active process.It constantly involves guessing,predicting checking and asking oneself questions. People usually read different things for different purposes.In general there are three main reasons why people read.One is reading for survival,for example read the label on a medicine bottle.The next one is reading for learning and information.The last one is reading for entertainment or pleasure,For English teaching,the main purpose for is the second one. In my practical teaching.I have found some students are not active in reading lessons;they are boring about reading lessons when they do some reading or answering activities.It seems that they are forced to do or they have to do.So my problem is how to arouse the students' interest and participation in reading lessons.

    Full Text Available The High Zagros region because of closing to subduction zone and the collision of the Arabian and Eurasian plates is imposed under the most tectonic variations. In this research, Gharasu river basin that it has located in Kermanshah area was selected as the study area and 6 geomorphic indices were calculated and the results of each ones were divided in 3 classes. Then, using the indices, relative tectonic activity was calculated and the values were classified and analyzed in 4 groups. Regions were identified as very high, high, moderate and low. In analyzing the results and combining them with field observation and regional geology the results are often associated and justified with field evidences. The highest value is located on Dokeral anticline in crush zone in Zagros Most of the areas with high and moderate values of lat are located on crush zone in Zagros too. Crushing of this zone is because of main faults mechanism of Zagros region. The result of this paper confirms previous researches in this region. At the end of the eastern part of the study area, the value of Iat is high that could be the result of Sarab and Koh-e Sefid faults mechanism.

    Full Text Available There is increasingly broad global recognition of the need to better understand determinants of vaccine acceptance. Fifteen social science, communication, health, and medical professionals (the “Motors of Trust in Vaccination” (MOTIV think tank explored factors relating to vaccination decision-making as a step to building a multidisciplinary research agenda. One hundred and forty seven factors impacting decisions made by consumers, professionals, and policy makers on vaccine acceptance, delay, or refusal were identified and grouped into three major categories: cognition and decision-making; groups and social norms; and communication and engagement. These factors should help frame a multidisciplinary research agenda to build an evidence base on the determinants of vaccine acceptance to inform the development of interventions and vaccination policies.

    Geodesy Observatory Pecný (GOP) provides one of the International DORIS Service (IDS) analyses centers, participating on the combined IDS products including the solution for ITRF2014. As the unique approach, GOP employs a DORIS-developed version of the Bernese GPS Software. The recent research focuses on several topics. Our experiment, based on 9 year of data, shows a possibility to reach LOD estimation accuracy close to 0.1 msec per day (compared to reference IERS C04 model), when not adjusting the cross-track harmonics in the Satellite orbit model. We also compare different preprocessing strategies and data weighting and discuss the impact on the solution accuracy and on the scale bias. Moreover, we present the initial results of the station clock modelling from the DORIS/pseudorange measurements.

    The experiments performed on the thirteen university-owned spectrometers installed at JRR-3M of JAERI in the fiscal year of 1997 were described in this report. The latest ``Neutron News`` (vol. 9, issue 3, 1998) has featured highlights of the activities based on the JRR-3M and its cover displays a graph showing an endless increase of the number of proposals to the users program in the fiscal 1997. The university-owned spectrometers are available for general users all over Japan. The users` requirement for a higher flux beam reactor became larger and larger with time. Thus, JAERI has refurbished JRR-3 to satisfy these demands. In 1997, a joint project between Chiba University and Institute for Solid State Physics (ISSP) started to build a new 4-cycle diffractometer for crystal physics/chemistry at T{sub 2-2} beam port on a thermal guide.

    2004-12-01

    The development of relational databases has significantly improved the performance of storage, search, and retrieval functions and has made it possible for applications that perform real-time data acquisition and analysis to interact with these types of databases. The purpose of this research was to develop a user interface for interaction between a data acquisition and analysis application and a relational database using the Oracle9i system. The overall system was designed to have an indexing capability that threads into the data acquisition and analysis programs. Tables were designed and relations within the database for indexing the files and information contained within the files were established. The system provides retrieval capabilities over a broad range of media, including analog, event, and video data types. The system's ability to interact with a data capturing program at the time of the experiment to create both multimedia files as well as the meta-data entries in the relational database avoids manual entries in the database and ensures data integrity and completeness for further interaction with the data by analysis applications.

    2016-02-01

    Congenital cataract is the common cause of visual disability in children. Nearly one third of congenital cataract cases may have a related genetic mutation. With the development of molecular genetics, especially gentechnik, more and more genes, such as crystallin genes, membrane protein genes, eytoskeletal protein genes and regulatory protein genes have been confirmed to participate in the process of congenital cataract. Furthermore, crystallin genes account for most of these genes and the crystallin has the highest amount of the whole protein in lens.It has been found that nearly one hundred mutations in crystallin genes are associated with the onset of congenital cataract. Researchers are exploring how these mutations further affect the function of cellular biology and eventually lead to cataract. Although more and more research results gradually reveal the pathogenesis of congenital cataract from the level of gene and protein, the specific pathogenesis is still unclear. The recent progression about inherited congenital cataract related with crysallin genes is summarized in this review.

  6. The travel-related carbon dioxide emissions of atmospheric researchers

    2008-04-01

    Full Text Available Most atmospheric scientists agree that greenhouse gas emissions have already caused significant changes to the global climate system and that these changes will accelerate in the near future. At the same time, atmospheric scientists who – like other scientists – rely on international collaboration and information exchange travel a lot and, thereby, cause substantial emissions of carbon dioxide (CO2. In this paper, the CO2 emissions of the employees working at an atmospheric research institute (the Norwegian Institute for Air Research, NILU caused by all types of business travel (conference visits, workshops, field campaigns, instrument maintainance, etc. were calculated for the years 2005–2007. It is estimated that more than 90% of the emissions were caused by air travel, 3% by ground travel and 5% by hotel usage. The travel-related annual emissions were between 1.9 and 2.4 t CO2 per employee or between 3.9 and 5.5 t CO2 per scientist. For comparison, the total annual per capita CO2 emissions are 4.5 t worldwide, 1.2 t for India, 3.8 t for China, 5.9 t for Sweden and 19.1 t for Norway. The travel-related CO2 emissions of a NILU scientist, occurring in 24 days of a year on average, exceed the global average annual per capita emission. Norway's per-capita CO2 emissions are among the highest in the world, mostly because of the emissions from the oil industry. If the emissions per NILU scientist derived in this paper are taken as representative for the average Norwegian researcher, travel by Norwegian scientists would nevertheless account for a substantial 0.2% of Norway's total CO2 emissions. Since most of the travel-related emissions are due to air travel, water vapor emissions, ozone production and contrail formation further increase the relative importance of NILU's travel in terms of radiative forcing.

    Full Text Available A new trend called “revolution of innovation” is clear visible in the development of the modern economy. Its benefits can be maximized through the rational approach to innovation activity management, knowledge management (treated as a source of innovation and systemic connection between the science with industry and customers in the process of creating value. The content of the publication is thus the concept of systematic approach to innovation activity management, with special emphasis on the commercialization of innovation, and using of knowledge as a source of innovation. Three models of approach to management are proposed: 1 model of rational organization management, 2 model of conceptual structure of innovative activity management, 3 model of integration of knowledge management and innovation management. Management according to the proposed models allows to use resources of various organizations in creating value materialized in innovations in the optimal way, especially in the context of the relatively low impact of universities and research organizations on creating ideas of innovations.

    2013-03-01

    Full Text Available Although smallpox was eradicated over 30 years ago, the disease remains a major threat. High mortality, high infectivity and low resistance of the contemporary population make the smallpox virus very attractive to terrorists. The possible presence of illegal stocks of the virus or risk of deliberate genetic modifications cause serious concerns among experts. Hence, it is reasonable to seek effective drugs that could be used in case of smallpox outbreak. This paper reviews studies on compounds with proven in vitro or in vivo antipoxviruses potential, which show various mechanisms of action. Nucleoside analogues, such as cidofovir, can inhibit virus replication. Cidofovir derivatives are developed to improve the bioavailability of the drug. Among the nucleoside analogues under current investigation are: ANO (adenozine N[sub]1[/sub]-oxide and its derivatives, N-methanocarbothymidine [(N-MCT], or derivatitives of aciklovir, peninclovir and brivudin. Recently, ST-246 – which effectively inhibits infection by limiting release of progeny virions – has become an object of attention. It has been also been demonstrated that compounds such as: nigericin, aptamers and peptides may have antiviral potential. An interesting strategy to fight infections was presented in experiments aimed at defining the role of individual genes (E3L, K3L or C6L in the pathogenesis, and looking for their potential blockers. Additionally, among substances considered to be effective in the treatment of smallpox cases, there are factors that can block viral inhibitors of the human complement system, epidermal growth factor inhibitors or immunomodulators. Further studies on compounds with activity against poxviruses are necessary in order to broaden the pool of available means that could be used in the case of a new outbreak of smallpox.

    Declining productivity with decreasing new molecular entity output combined with increased R&D spending is one of the key challenges for the entire pharmaceutical industry. In order to offset decreasing new molecular entity output, life-cycle management activities for established drugs become more and more important to maintain or even expand clinical indication and market opportunities. Life-cycle management covers a whole range of activities from strategic pricing to a next generation product launch. In this communication, we review how research organizations can contribute to successful life-cycle management strategies using phosphodiesterase 5 inhibitors as an example.

    Objective The aim of the present study was to describe the research activities being undertaken by health service employees within one Australian health service and explore their experiences with undertaking research.Methods The present mixed-methods study was conducted across one health service in Queensland, Australia, and included a cross-sectional online survey and interviews with healthcare service employees. The anonymous survey was a self-administered online questionnaire, distributed to all 6121 employees at the health service via email, asking about research activity and engagement. Willing participants were also interviewed on their perceptions and experiences with research and capacity building.Results In all, 151 participants responded to the survey and 22 participated in interviews. Three-quarters of respondents reported actively participating in research over the past 6 years and several research outputs, such as publications, conference presentations and competitive grant funding, were displayed. Four concepts emerged from interview findings, namely collaborative partnerships, skilled mentorship, embedding research and organisational support, which represented the overall theme 'opportunities for a research-infused health service'.Conclusion Employees of the health service recognised the importance of research and had a range of research skills, knowledge and experience. They also identified several opportunities for building research capacity in this service.What is known about the topic? Building research capacity among healthcare professionals is important for enabling the conduct of high-quality research in healthcare institutions. However, building research capacity is complex and influenced by the uniqueness of organisational context. In order to successfully build research capacity among employees at any health service, current research activity, skills and experience, as well as staff perceptions around building research capacity in that

    International migration has emerged as a global issue that has transformed the lives of hundreds of millions of persons. Migrant workers contribute to the economic growth of high-income countries often serving as the labour force performing dangerous, dirty and degrading work that nationals are reluctant to perform. Critical examination of the scientific and "grey" literatures on immigration, employment relations and health. Both lay and scientific literatures indicate that public health researchers should be concerned about the health consequences of migration processes. Migrant workers are more represented in dangerous industries and in hazardous jobs, occupations and tasks. They are often hired as labourers in precarious jobs with poverty wages and experience more serious abuse and exploitation at the workplace. Also, analyses document migrant workers' problems of social exclusion, lack of health and safety training, fear of reprisals for demanding better working conditions, linguistic and cultural barriers that minimize the effectiveness of training, incomplete OHS surveillance of foreign workers and difficulty accessing care and compensation when injured. Therefore migrant status can be an important source of occupational health inequalities. Available evidence shows that the employment conditions and associated work organization of most migrant workers are dangerous to their health. The overall impact of immigration on population health, however, still is poorly understood and many mechanisms, pathways and overall health impact are poorly documented. Current limitations highlight the need to engage in explicit analytical, intervention and policy research. (c) 2009 Wiley-Liss, Inc.

  16. Transformative potential of participatory research: Deconstructing power relations between a child and an adult

    Directory of Open Access Journals (Sweden)

    Vranješević Jelena

    2016-01-01

    Full Text Available Transformative potential of participatory research with children as participants is reflected in promoting the image of the child as an active actor in the social community, an equal partner whose voice is heard and appreciated, as well as in a critical reconsideration of an adult-centred perspective in research, based on hierarchical power relations between children and adults. The paper critically discusses the theoretical and methodological grounds which serve as the basis for the adult-centred perspective and analyses the factors that have significantly contributed to the change in research paradigm when it comes to the status of children in research: critical re-examination of methodology and objectives of certain social sciences, the movements calling for the emancipation of marginalised social groups and new policies in the field of protecting children’s rights. Transformative potential of participatory research is discussed both from the perspective of the role and position of adults in research process (adults’ responsibility: personal and epistemological reflexivity and the relationship between adults and children in research (the change of attitudes towards children and redefining the traditional roles of adults and children: the cooperative vs. hierarchical model of power, as well as in relation to: the change in the position of research participants (children, visibility of their perspective in public discourse and the development of competences and values important for living in a democratic society.

    1984-01-01

    The etiology of erectile failure is not always clear despite the fact that recordings of nocturnal penile tumescence (NPT) are used to detect patients with a significant organic component to their complaint. We recorded electrodermal activity in addition to NPT in 60 impotent patients. Normally more electrodermal activity occurs in stage 2 than in stage REM sleep. Despite a similar total amount of electrodermal activity, organically impotent patients tended to have less electrodermal activity in stage 2 and more in stage REM sleep than those with normal NPT. This difference was due to a subgroup of 15 organically impotent patients with less electrodermal activity in stage 2 than in stage REM sleep. Because of this difference in the pattern of electrodermal activity in relation to sleep stages, the results suggest a central nervous system change is related to impaired erectile capability and abnormal NPT in these cases.

    2011-01-01

    In this article, we present the effects of three hypothesized protective factors: social activities, school-related activities, and anti-substance use media messages on adolescent tobacco and alcohol use. Data were drawn from the "Monitoring the Future" (MTF) research project, which was conducted by the Institute for Social Research at the University of Michigan. The sample included 2,551 twelfth-grade students. The results of the structural equation model showed that exposure to media anti-drug messages had an indirect negative effect on tobacco and alcohol use through school-related activity and social activity. The results suggest that comprehensive ecological interventions encompassing media, family, and school can increase on the preventive effects of adolescent's substance use.

    The costs of performing research are an important input in value of information (VOI) analyses but are difficult to assess. The aim of this study was to investigate the costs of research, serving two purposes: (1) estimating research costs for use in VOI analyses; and (2) developing a costing tool to support reviewers of grant proposals in assessing whether the proposed budget is realistic. For granted study proposals from the Netherlands Organization for Health Research and Development (ZonMw), type of study, potential cost drivers, proposed budget, and general characteristics were extracted. Regression analysis was conducted in an attempt to generate a 'predicted budget' for certain combinations of cost drivers, for implementation in the costing tool. Of 133 drug-related research grant proposals, 74 were included for complete data extraction. Because an association between cost drivers and budgets was not confirmed, we could not generate a predicted budget based on regression analysis, but only historic reference budgets given certain study characteristics. The costing tool was designed accordingly, i.e. with given selection criteria the tool returns the range of budgets in comparable studies. This range can be used in VOI analysis to estimate whether the expected net benefit of sampling will be positive to decide upon the net value of future research. The absence of association between study characteristics and budgets may indicate inconsistencies in the budgeting or granting process. Nonetheless, the tool generates useful information on historical budgets, and the option to formally relate VOI to budgets. To our knowledge, this is the first attempt at creating such a tool, which can be complemented with new studies being granted, enlarging the underlying database and keeping estimates up to date.

    Objective To consider the research gaps related to the environmental impacts of electronic cigarettes due to their manufacture, use and disposal. Methods Literature searches were conducted through December 2013. Studies were included in this review if they related to the environmental impacts of e-cigarettes. Results Scientific information on the environmental impacts of e-cigarette manufacturing, use and disposal is very limited. No studies formally evaluated the environmental impacts of the manufacturing process or disposal of components, including batteries. Four studies evaluated potential exposure to secondhand e-cigarette aerosol, an indication of impacts on indoor air quality. A 2010 survey of six e-cigarette models found that none of the products provided disposal instructions for spent cartridges containing nicotine. Notably, some e-cigarette manufacturers claim their e-cigarettes are ‘eco-friendly’ or ‘green’, despite the lack of any supporting data or environmental impact studies. Some authors argue that such advertising may boost sales and increase e-cigarette appeal, especially among adolescents. Conclusions Little is known about the environmental impacts of e-cigarettes, and a number of topics could be further elucidated by additional investigation. These topics include potential environmental impacts related to manufacturing, use and disposal. The environmental impacts of e-cigarette manufacturing will depend upon factory size and the nicotine extracting method used. The environmental impacts of e-cigarette use will include chemical and aerosol exposure in the indoor environment. The environmental impacts of disposal of e-cigarette cartridges (which contain residual nicotine) and disposal of e-cigarettes (which contain batteries) represent yet another environmental concern.

    The differences in using a "social isolation" concept in the psychological literature are presented. The term of "relative social isolation" is clarified. A relationship between human adaptation to the relative social isolation environments and the development of his social qualities and social activities is presented. The "social context", dictating motivation attitudes of a man to the isolation situation, emotional experiences, self-appraisal of activity is of crucial importance for evaluating the real environments of relative social isolations. Social activity of a personality is studied as the relations of a man with the conditions of his activity. The results of studying the dynamics of the psychic state of a man during individual and group isolation are compared. It is concluded that social activity of man and his functional state are interrelated. The particular manifestations and direction of the changes in the social activity of the subject depend on the duration of isolation and are determined first of all by social significance and meaningful and balanced work for a person as well as by the amount and frequency of direct and mediated social contacts under specific conditions of relative social isolation.

    Full Text Available A long time economic and social objectives have been seen as competing, but academic researchers underline that this two directions may converge in certain situations. Companies belong to communities where they develop their activities. When the social goals of the communities are related to the main objectives of the company, sustaining a social cause could produce economic benefits, in this case corporate philanthropy and shareholders interest take the same direction. Cause-related marketing is a marketing concept that gained more interest in the last three decades and exemplifies how social and economic objectives are achieved in a strategic manner in promoting campaigns. Researches in business and non-profit organizations reveal that cause-related marketing campaigns sustain the growth of market share and sales, and help at improving brands image. More and more companies and non-profit organizations find cause-related marketing as a strategic tool suitable for building long term relations to the customers, for increasing brand awareness, for gaining a social responsible corporative image, for supporting local community or for producing transformation in sustaining causes at global or international level. The study analyses the definitions of cause-related marketing the presence and evolution of the concept in the academic literature, and marketing terms that are connected more often to this concept. Comparative to non-profit marketing concept, cause-related marketing gained a larger interest in literature. On the other side, corporate philanthropy is still a concept that gains more interest than cause-related marketing in academic literature, being a more commune way used by companies in collaboration to non-profit organizations. Tided to cause-related marketing concept literature review reveals concepts as: consumer behaviour, brand image and corporate social responsibility being more often analysed.

    Full Text Available Abstract Background Research on the relationship between Health Related Quality of Life (HRQoL and physical activity (PA, to date, have rarely investigated how this relationship differ across objective and subjective measures of PA. The aim of this paper is to explore the relationship between HRQoL and PA, and examine how this relationship differs across objective and subjective measures of PA, within the context of a large representative national survey from England. Methods Using a sample of 5,537 adults (40–60 years from a representative national survey in England (Health Survey for England 2008, Tobit regressions with upper censoring was employed to model the association between HRQoL and objective, and subjective measures of PA controlling for potential confounders. We tested the robustness of this relationship across specific types of PA. HRQoL was assessed using the summary measure of health state utility value derived from the EuroQol-5 Dimensions (EQ-5D whilst PA was assessed via subjective measure (questionnaire and objective measure (accelerometer- actigraph model GT1M. The actigraph was worn (at the waist for 7 days (during waking hours by a randomly selected sub-sample of the HSE 2008 respondents (4,507 adults – 16 plus years, with a valid day constituting 10 hours. Analysis was conducted in 2010. Results Findings suggest that higher levels of PA are associated with better HRQoL (regression coefficient: 0.026 to 0.072. This relationship is consistent across different measures and types of PA although differences in the magnitude of HRQoL benefit associated with objective and subjective (regression coefficient: 0.047 measures of PA are noticeable, with the former measure being associated with a relatively better HRQoL (regression coefficient: 0.072. Conclusion Higher levels of PA are associated with better HRQoL. Using an objective measure of PA compared with subjective shows a relatively better HRQoL.

    Complement factor H-related proteins (FHRs) are strongly associated with different diseases involving complement dysregulation, which suggests a major role for these proteins regulating complement activation. Because FHRs are evolutionarily and structurally related to complement inhibitor factor H (FH), the initial assumption was that the FHRs are also negative complement regulators. Whereas weak complement inhibiting activities were originally reported for these molecules, recent developments indicate that FHRs may enhance complement activation, with important implications for the role of these proteins in health and disease. We review these findings here, and propose that FHRs represent a complex set of surface recognition molecules that, by competing with FH, provide improved discrimination of self and non-self surfaces and play a central role in determining appropriate activation of the complement pathway.

    Impairments in the ability to recollect specific details of personally experienced events are one of the main cognitive changes associated with aging. Cognitive training can improve older adults' recollection. However, little is currently known regarding the neural correlates of these training-related changes in recollection. Prior research suggests that the hippocampus plays a central role in supporting recollection in young and older adults, and that age-related changes in hippocampal function may lead to age-related changes in recollection. The present study investigated whether cognitive training-related increases in older adults' recollection are associated with changes in their hippocampal activity during memory retrieval. Older adults' hippocampal activity during retrieval was examined before and after they were trained to use semantic encoding strategies to intentionally encode words. Training-related changes in recollection were positively correlated with training-related changes in activity for old words in the hippocampus bilaterally. Positive correlations were also found between training-related changes in activity in prefrontal and left lateral temporal regions associated with self-initiated semantic strategy use during encoding and training-related changes in right hippocampal activity associated with recollection during retrieval. These results suggest that cognitive training-related improvements in older adults' recollection can be supported by changes in their hippocampal activity during retrieval. They also suggest that age differences in cognitive processes engaged during encoding are a significant contributor to age differences in recollection during retrieval.

    Public open spaces such as parks and green spaces are key built environment elements within neighbourhoods for encouraging a variety of physical activity behaviours. Over the past decade, there has been a burgeoning number of active living research studies examining the influence of public open space on physical activity. However, the evidence shows mixed associations between different aspects of public open space (e.g., proximity, size, quality) and physical activity. These inconsistencies hinder the development of specific evidence-based guidelines for urban designers and policy-makers for (re)designing public open space to encourage physical activity. This paper aims to move this research agenda forward, by identifying key conceptual and methodological issues that may contribute to inconsistencies in research examining relations between public open space and physical activity.

    Full Text Available In the present study a model for the oxygen concentration profiles in a mobile bed biofilm reactor (MBBR is proposed. By using a material with a large specific surface area (m2/m3 high biological activity can be maintained using a relatively small reactor volume. Small parts made of special materials with density close to the water density, are immersed in the bioreactors. The biofilm carriers are kept in suspension and even mixed with the help of air bubbles generated by the aeration system. Water oxygenation is a mass transfer process of oxygen from gas/air to the liquid mass. It can be used in wastewater treatment in order to remove the organic matter, in the biological stage. The functioning of aerobic processes depends on the availability of sufficient quantities of oxygen. In wastewater treatment plants, submerged bubbles aeration is most frequently accomplished by dispersing air bubbles in the liquid. The main purpose of this study is to determine the concentration of dissolved oxygen using mathematical modeling and numerical simulations. The aim of the study is to find the optimum dimension and position of the aeration pipes for maintaining the oxygen concentration in the limits indicated in the literature. Experimental determinations (measurements of the DO concentration have also been realized. The oxygen profile concentration, in a MBBR reactor, was determined.

    The aim of this study was to examine the associations between the body-related self-conscious emotions of shame, guilt, and pride and physical activity motivation and behavior among adult males. Specifically, motivation regulations (external, introjected, indentified, intrinsic) were examined as possible mediators between each of the body-related self-conscious emotions and physical activity behavior. A cross-sectional study was conducted with adult men (N = 152; Mage = 23.72, SD = 10.92 years). Participants completed a questionnaire assessing body-related shame, guilt, authentic pride, hubristic pride, motivational regulations, and leisure-time physical activity. In separate multiple mediation models, body-related shame was positively associated with external and introjected regulations and negatively correlated with intrinsic regulation. Guilt was positively linked to external, introjected, and identified regulations. Authentic pride was negatively related to external regulation and positively correlated with both identified and intrinsic regulations and directly associated with physical activity behavior. Hubristic pride was positively associated with intrinsic regulation. Overall, there were both direct and indirect effects via motivation regulations between body-related self-conscious emotions and physical activity (R(2) shame = .15, guilt = .16, authentic pride = .18, hubristic pride = .16). These findings highlight the importance of targeting and understanding self-conscious emotions contextualized to the body and links to motivation and positive health behavior among men.

    2012-01-01

    Full Text Available A number of organizations have employed a consultative process with the vision community to engage relevant parties in identifying needs and opportunities for vision research. The National Eye Institute in the US and the European Commission are currently undergoing consultation to develop priorities for vision research. Once these priorities have been established, the challenge will be to identify the resources to advance these research agendas. Success rates for Federal funding for research have decreased recently in the USA, UK, and Australia. Researchers should consider various potential funding sources for their research. The universal consideration for funding is that the reason for funding should align with the mission of the funding organization. In addition to Federal research organizations that fund investigator-initiated research, other potential funding sources include nongovernmental organizations, for-profit companies, individual philanthropy, and service organizations. In addition to aligning with organizational funding priorities, researchers need to consider turn-around time and total funds available including whether an organization will cover institutional indirect costs. Websites are useful tools to find information about organizations that fund research, including grant deadlines. Collaboration is encouraged.

    2016-03-04

    Substrate activity screening (SAS) was presented a decade ago by Ellman and co-workers as a straightforward methodology for the identification of fragment-sized building blocks for enzyme inhibitors. Ever since, SAS and variations derived from it have been successfully applied to the discovery of inhibitors of various families of enzymatically active drug targets. This review covers key achievements and challenges of SAS and related methodologies, including the modified substrate activity screening (MSAS) approach. Special attention is given to the kinetic and thermodynamic aspects of these methodologies, as a thorough understanding thereof is crucial for successfully transforming the identified fragment-sized hits into potent inhibitors.

    Soy isoflavones have been studied extensively for estrogenic and antiestrogenic properties. Other flavonoids, found in fruits, vegetables, tea and wine, have been much less tested for steroid hormone activity. We therefore assessed the estrogenic, androgenic and progestational activities of 72 flavonoids and structurally-related compounds. These compounds were tested on BT-474 human breast cancer cells at concentrations of 10(8)-10(-5) M, with estradiol (estrogen), norgestrel (progestin) and dihydrotestosterone (androgen) used as positive controls, and ethanol (solvent) as a negative control. pS2, an estrogen-regulated protein, and prostate-specific antigen (PSA), regulated by androgens and progestins, were quantified in tissue culture supernatants using ELISA-type immunofluorometric assays developed in-house. Of the 72 compounds tested, 18 showed estrogenic activity at 10(-5) M. Of this subset, seven also showed progestational activity at this concentration. The soy isoflavones, biochanin A and genistein, showed the most potent estrogenic activity, with a dose-response effect up to 10(-7) M. Of all other flavonoids, luteolin and naringenin displayed the strongest estrogenicity, while apigenin had a relatively strong progestational activity. Based on our data, we have formulated a set of structure/function relationships between the tested compounds. Flavonoids, therefore, exhibit significant steroid hormone activity, and may have an effect in the modification of cancer risk by diet, or in cancer therapeutics and prevention.

    The Pulmonary Hypertension Association (PHA) is a patient advocacy organization seeking to find ways to prevent, improve treatment for, and cure pulmonary hypertension (PH) and to provide hope for the PH community through support, education, research, advocacy, and awareness. Many patients involved with PHA are also involved in various PH-specific research studies; however, the patient expectations and priorities for PH-specific research are currently unknown or not well examined. Our objective was to identify the current modes of study entry, priorities within research, and expectations over the course of study involvement for patient constituents of PHA. A 29-question online survey was designed by PHA and disseminated to the PHA patient constituency on its Facebook page through a post on November 29, 2012. Responses were collected on SurveyMonkey through December 10, 2012. Respondents were divided into parallel survey tracks, depending on whether the respondent indicated previous participation in research studies. These two cohorts of individuals were analyzed and, where appropriate, compared with tests of association. A total of 234 respondents were included in the final data analysis, with 95 (40.6%) reporting previous participation in research studies. These respondents reported an overall positive experience in their research studies (64.9% very good, 21.3% good, 12.8% neutral, 1.1% bad). Of the respondents with previous research study participation, 91.1% indicated that receipt of the study outcome after participation would positively influence their decision to participate in future research; despite this, only 41.17% reported receiving information of this sort after their participation. Research participation is a strong interest of PHA patient constituents; clear and consistent communication from the research team is an expectation of many participants. Despite this expectation, 58.83% of respondents indicated they did not receive communication from the

In order to effectively address these burdens, appropriately-trained scientists who conduct high-impact neuroscience research will be needed. Additionally, research directions should be aligned with national research priorities. However, to provide information about current neuroscience research productivity and direction, the existing capacity and focus need to be identified. This would allow opportunities for collaborative research and training to be properly explored and developmental interventions to be better targeted. In this study, we sought to evaluate the existing capacity and direction of neuroscience-related research in Ghana. To do this, we examined publications reporting research investigations authored by scientists affiliated with Ghanaian institutions in specific areas of neuroscience over the last two decades (1995-2015). 127 articles that met our inclusion criteria were systematically evaluated in terms of research foci, annual publication trends and author affiliations. The most actively-researched areas identified include neurocognitive impairments in non-nervous system disorders, depression and suicide, epilepsy and seizures, neurological impact of substance misuse, and neurological disorders. These studies were mostly hospital and community-based surveys. About 60% of these articles were published in the last seven years, suggesting a recent increase in research productivity. However, data on experimental and clinical research outcomes were particularly lacking. We suggest that future investigations should focus on the following specific areas where information was lacking: large-scale disease epidemiology, effectiveness of diagnostic platforms and therapeutic treatments, and the genetic, genomic and molecular bases of diseases.

    Acosta, O M; Albus, K E; Reynolds, M W; Spriggs, D; Weist, M D

    2001-06-01

    Presents results of a systematic review of abstracts on studies related to violence and youth in an effort to identify areas that have received little attention in the psychological literature and to present recommendations for future research. A total of 1,168 empirical articles on violence-related problems in youth were identified by a PsycINFO (American Psychological Association, 1980-1999) search. These articles were then classified in a multidimensional grid, allowing for comparisons among different types of articles. A review of abstracts from these articles indicated that most of the research activity has been descriptive (e.g., reviewing correlates or predictors of violence involvement) or assessment related (e.g., evaluating specific measures). Fewer articles examined the treatment or prevention of violence-related problems among youth. Further, the majority of studies pertained to direct exposure to violence (as a victim or perpetrator), with very few studies looking at the effects of witnessing violence, knowing individuals exposed to violence, or being exposed to violence through the media. Comparing treatment and prevention articles, we found that the least empirical attention was paid to the prevention of violence-related problems in youth, and not a single study was identified through this search that sought to examine the prevention of youth witnessing violence. Implications for future research agendas are discussed.

    Deng Qidong; Wen Xueze

    2009-01-01

    This paper reviews the history and progress of research on active tectonics in China and overseas. By giving a brief introduction on the history of active tectonic research in China and other countries, the paper sums up the process and development of quantitative investigation of active tectonics since the 1980s. The focus is on the main efforts and progress made in China on certain aspects of research, such as basic surveys and applied investigation of active tectonics, the study of theories related to regional active tectonics and their kinematics and geodynamics, surveys on coupling relations between deep and shallow structures, active fault surveys and prospecting and seismic hazard assessment in urban areas, as well as the efforts made using Quaternary geochronology. Furthermore, the paper looks back on Chinese quantitative investigation of active tectonics in China and sums up cognitions derived from studies on the determination of several basic and measurable parameters of active tectonics. These parameters include the length of fault and fault segmentation, coseismic slip and cumulative slip, fault slip rate, the sequence of paleoearthquake events and the time elapsed since the most recent event. At the same time, efforts and progress made in China on assessing the long-term seismic potential for active faults and evaluating the risk from potential active fault movement have been reviewed by summarizing research on developing theories, models, methods and the application of time-dependent seismic potential to prohabilistic assessment, magnitude estimation for potential earthquakes on active faults, and the forecast of potential risk caused by active fault movement. Finally, in consideration of the realities and problems in the research of active tectonics in China, the authors put forward several suggestions for issues worthy of more attention for further investigation in the future.

  20. Medial Temporal Lobe Activity Predicts Successful Relational Memory Binding

    2009-01-01

    Previous neuropsychological findings have implicated medial temporal lobe (MTL) structures in retaining object-location relations over the course of short delays, but MTL effects have not always been reported in neuroimaging investigations with similar short-term memory requirements. Here, we used event-related functional magnetic resonance imaging to test the hypothesis that the hippocampus and related MTL structures support accurate retention of relational memory representations, even across short delays. On every trial, four objects were presented, each in one of nine possible locations of a three-dimensional grid. Participants were to mentally rotate the grid and then maintain the rotated representation in anticipation of a test stimulus: a rendering of the grid, rotated 90° from the original viewpoint. The test stimulus was either a “match” display, in which object-location relations were intact, or a “mismatch” display, in which one object occupied a new, previously unfilled location (mismatch position), or two objects had swapped locations (mismatch swap). Encoding phase activation in anterior and posterior regions of the left hippocampus, and in bilateral perirhinal cortex, predicted subsequent accuracy on the short-term memory decision, as did bilateral posterior hippocampal activity after the test stimulus. Notably, activation in these posterior hippocampal regions was also sensitive to the degree to which object-location bindings were preserved in the test stimulus; activation was greatest for match displays, followed by mismatch-position displays, and finally mismatch-swap displays. These results indicate that the hippocampus and related MTL structures contribute to successful encoding and retrieval of relational information in visual short-term memory. PMID:18171929

  1. The coordination of research and innovation activities relative to an emergent technology: the case of batteries for electric and hybrid vehicles; La coordination des activites de recherche et d'innovation dans les phases d'emergence: le cas des batteries pour vehicules electriques et hybrides

    Larrue, Ph.

    In this thesis, we try to provide elements of a non-deterministic view of the coordination of research activities in the phase of emergence. Firstly, we try to identify the variables that determinate the strength and the characteristics of the imperative of coordination in this very preliminary period of an innovation process. Secondly, we try to evaluate the institutional arrangements that can effectively sustain the coordination of the activities of the various interdependent actors more or less involved in the innovation process. The basic idea of the thesis is that technological innovations do not originate as isolated according to a hypothetical underlying 'nature of the technology', especially when they are controversial and subject to great uncertainties as is the case with regard to batteries for Electric and hybrid Vehicles (EVs). Innovations appear to be generated by means of the interactions of a number of organizations belonging to different 'spheres' (different industries, scientific disciplines, public institutions, etc.). In order to validate a new area of opportunity which is still very uncertain at this preliminary stage, the competences and interests of these different organizations must be coordinated. Because of the complex mix of economic and technological barriers faced by the actors taking part in this innovation process, the area of batteries for electric and hybrid vehicles is the 'perfect laboratory' to investigate the institutional arrangements that can sustain the coordination of research and innovation activities relating to an emerging technology. The empirical and theoretical investigations are mainly focused on pre-competitive research consortia such as the United-States Advanced Battery Consortium (USABC). This case study is conducted through in-depth interviews with key-actors of the area of batteries and electric vehicles. We also use the results of an on-line experts opinions survey we performed

  4. Medical student stories of participation in patient care-related activities: the construction of relational identity.

    Science.gov (United States)

    Warmington, Sally; McColl, Geoffrey

    2017-03-01

    Professional identity formation is acknowledged as one of the fundamental tasks of contemporary medical education. Identity is a social phenomenon, constructed through participation in everyday activities and an integral part of every learning interaction. In this paper we report from an Australian ethnographic study into how medical students and patients use narrative to construct their identities. The dialogic narrative analysis employed focused on the production of meaning through the use of language devices in a given context, and the juxtaposition of multiple perspectives. Two stories told by students about their participation in patient care-related activities reveal how identities are constructed in this context through depictions of the relationships between medical students, patients and clinical teachers. These students use the rhetorical functions of stories to characterise doctors and patients in certain ways, and position themselves in relation to them. They defend common practices that circumvent valid consent processes, justified by the imperative to maximise students' participation in patient care-related activities. In doing so, they identify patients as their adversaries, and doctors as allies. Both students are influenced by others' expectations but one reveals the active nature of identity work, describing subtle acts of resistance. These stories illustrate how practices for securing students' access to patients can influence students' emerging identities, with implications for their future disclosure and consent practices. We argue that more collaborative ways of involving medical students in patient care-related activities will be facilitated if students and clinical teachers develop insight into the relational nature of identity work.

    The neural mechanisms of music listening and appreciation are not yet completely understood. Based on the apparent relationship between the beats per minute (tempo) of music and the desire to move (for example feet tapping) induced while listening to that music it is hypothesised that musical tempo may evoke movement related activity in the brain. Participants are instructed to listen, without moving, to a large range of musical pieces spanning a range of styles and tempos during an electroencephalogram (EEG) experiment. Event-related desynchronisation (ERD) in the EEG is observed to correlate significantly with the variance of the tempo of the musical stimuli. This suggests that the dynamics of the beat of the music may induce movement related brain activity in the motor cortex. Furthermore, significant correlations are observed between EEG activity in the alpha band over the motor cortex and the bandpower of the music in the same frequency band over time. This relationship is observed to correlate with the strength of the ERD, suggesting entrainment of motor cortical activity relates to increased ERD strength.

    Stauning, P.

    2012-04-01

    The Polar Cap (PC) indices, PCN for the index values derived from Thule magnetic data and PCS derived from Vostok data, relate to the polar cap ionospheric plasma convection driven mainly by the interaction of the solar wind with the magnetosphere. Thus, the PC indices serve to monitor the input power from the solar wind which drives a range of geophysical disturbances such as magnetic storms and substorms, energization of the plasma trapped in the Earth's near space, auroral activity, and heating of the upper atmosphere. The presentation will demonstrate the relations between the PC indices and further parameters and indices used to describe geophysical activity such as polar cap potentials, auroral electrojet activity, Joule and particle heating of the upper atmosphere, mid-latitude magnetic variations, and ring current indices Dst, SYM-H and ASY-H.

  12. Extraction of Children's Friendship Relation from Activity Level

    Kono, Aki; Shintani, Kimio; Katsuki, Takuya; Kihara, Shin'ya; Ueda, Mari; Kaneda, Shigeo; Haga, Hirohide

    Children learn to fit into society through living in a group, and it's greatly influenced by their friend relations. Although preschool teachers need to observe them to assist in the growth of children's social progress and support the development each child's personality, only experienced teachers can watch over children while providing high-quality guidance. To resolve the problem, this paper proposes a mathematical and objective method that assists teachers with observation. It uses numerical data of activity level recorded by pedometers, and we make tree diagram called dendrogram based on hierarchical clustering with recorded activity level. Also, we calculate children's ``breadth'' and ``depth'' of friend relations by using more than one dendrogram. When we record children's activity level in a certain kindergarten for two months and evaluated the proposed method, the results usually coincide with remarks of teachers about the children.

    The French Cancer Plan 2014-2019 stresses the importance of strengthening collaboration between all stakeholders involved in the fight against cancer, including cancer cooperative groups and intergroups. This survey aimed to describe the basics characteristics and clinical research activity among the Cancer Cooperative Groups (Groupes coopérateurs en oncologie). The second objective was to identify facilitators and barriers to their research activity. A questionnaire was sent to all the clinicians involved in 2014 as investigators in a clinical trial sponsored by one of the ten members of the Cancer Cooperative Groups network. The questions were related to their profile, research activity and the infrastructure existing within their healthcare center to support clinical research and related compliance activities. In total, 366 investigators responded to our survey. The academic clinical trials sponsored by the Cancer Cooperative Groups represented an important part of the research activity of the investigators in France in 2014. These academic groups contributed to the opening of many research sites throughout all regions in France. Factors associated with a higher participation of investigators (more than 10 patients enrolled in a trial over a year) include the existing support of healthcare professionals (more than 2 clinical research associate (CRA) OR=11.16 [3.82-32.6] compared to none) and the practice of their research activity in a University Hospital Center (CHU) rather than a Hospital Center (CH) (OR=2.15 [1.20-3.83]). This study highlighted factors that can strengthen investigator clinical research activities and subsequently improve patient access to evidence-based new cancer therapies in France.

    This paper highlights the importance and value of involving people with a lived experience of mental ill health and recovery in neuroscience research activity. In this era of recovery oriented service delivery, involving people with the lived experience of mental illness in neuroscience research extends beyond their participation as "subjects". The recovery paradigm reconceptualises people with the lived experience of mental ill health as experts by experience. To support this contribution, local policies and procedures, recovery-oriented training for neuroscience researchers, and dialogue about the practical applications of neuroscience research, are required.

    2010-03-01

    Seagrass research in China is still in its infancy. Even though there has been progress recently, there is still a great deal of research needed to gain a better understanding of seagrass. In this article we review and discuss the advances in seagrass research in China from two aspects: (1) seagrass species and their distribution; (2) seagrass research in China, including studies on their taxonomy, ecology, photosynthesis, applications in aquaculture, salt-tolerance mechanisms and other research topics. A total of 18 seagrass species belonging to 8 genera are distributed in nine provinces and regions in China (including Hong Kong and Taiwan), as well as the Xisha and Nansha Archipelagos. They can be divided into two groups: a North China Group and a South China Group. Based on the seagrass distribution, the Chinese mainland coast can be divided into three sections: North China Seagrass Coast, Middle China Seagrass Coast, and South China Seagrass Coast. Ecological studies include research on seagrass communities, nutrient cycling in seagrass ecosystems, genetic diversity, pollution ecology and research in the key regions of Shandong, Guangdong, Guangxi, and Hainan. Seagrass species and their locations, community structure, ecological evaluation, epiphytes, ecological functions and threats in the key regions are also summarized. Other studies have focused on remote sensing of seagrass, threatened seagrass species of China, and pollen morphology of Halophila ovalis.

    Gomberg, Edith S Lisansky

    2003-01-01

    For the subgroups indicated, a few questions/issues are relevant to all three (women, elderly, minorities): 1. Heterogeneity of the special populations, for example, Hispanic-Americans are from different countries with different cultures. Women and the elderly vary by age, education, income, social class, health status, etc., to say nothing of ethnicity/color/religion. 2. Of therapy modalities, professional and indigenous, which are more efficacious? 3. Are group-specific therapies needed, or will sensitivity to a particular group work as well? WOMEN: Stereotypes and myths have prevailed, for example, the long-standing belief that women have poorer prognoses than male alcoholics. When female and male alcoholics are compared, women report more positive family history, a later onset of drinking and problems, more marital disruption, more comorbidity, etc. The review of treatment outcomes (Vannicelli, 1986) showed few significant gender differences in outcomes. Research recommendations include biological and genetic studies, women's view of and use of therapeutic modalities, and outcome studies of different modalities, including all female facilities. ELDERLY: Medications are used more by older patients, and such patients are more likely to experience adverse drug reactions. In the moderate social use of alcohol, there are conflicting reports and the extent of elderly use awaits decisive study. The etiology of problem drinking by older persons is studied rarely. An attempt has been made to explain onset later in life (vs. earlier onset) based on the stresses of aging (loss, loneliness, health problems, etc.); research results have not been supportive. Consequences of older persons' heavy drinking seems to be most often alcohol-related medical disorders, although there are often familial and social consequences. Atkinson (1995) recommended the development of elder-specific outcome measures, study of the efficacy of different treatment modalities, and study of the

    Full Text Available We have analyzed the popularization activities undertaken by ten thousand CNRS researchers by means of their annual reports for the years 2004, 2005 and 2006. This is the first time that such an extensive statistical study on science popularization practices is carried out. Our main findings are : - the majority of researchers is not involved in popularization (51% has not done any popularization over the three-year period, two thirds have been involved in no more than one popularization action. - popularization practices are extremely diverse, both at the individual level (we have identified three subpopulations that feature distinctive attitudes towards popularization, and at the level of scientific disciplines (researchers in Humanities are twice as active as the average, as well as in laboratories or geographical regions. - the number of actions reported in 2005 greatly increased compared to 2004 (+ 26%, while they slightly diminished in 2006.

    Laboratory studies have shown clear relationships between relative humidity (RH) and the activity and survival of Ixodes scapularis Say (blacklegged tick). However, field studies have produced conflicting results. We examined this relationship using weekly tick count totals and hourly RH observations at three field sites, stratified by latitude, within the state of Rhode Island. Records of nymphal tick abundance were compared with several RH-related variables (e.g., RH at time of sampling and mean weekly daytime RH). In total, 825 nymphs were sampled in 2009, a year of greater precipitation, with a weighted average leaf litter RH recorded at time of sampling of 85.22%. Alternatively, 649 nymphs were collected in 2010, a year of relatively low precipitation, and a weighted average RH recorded at time of sampling was 75.51%. Negative binomial regression analysis of tick count totals identified cumulative hours <82% RH threshold as a significant factor observed in both years (2009: P = 0.0037; 2010: P < 0.0001). Mean weekly daytime RH did not significantly predict tick activity in either year. However, mean weekly daytime RH recorded with 1-wk lag before sample date was a significant variable (P = 0.0016) in 2010. These results suggest a lag effect between moisture availability and patterns of tick activity and abundance. Differences in the relative importance of each RH variable between years may have been due to abnormally wet summer conditions in 2009.

    Dysregulation of the alternative pathway (AP) of complement cascade has been implicated in the pathogenesis of age-related macular degeneration (AMD), the leading cause of blindness in the elderly. To further test the hypothesis that defective control of complement activation underlies AMD, parameters of complement activation in blood plasma were determined together with disease-associated genetic markers in AMD patients. Plasma concentrations of activation products C3d, Ba, C3a, C5a, SC5b-9, substrate proteins C3, C4, factor B and regulators factor H and factor D were quantified in patients (n = 112) and controls (n = 67). Subjects were analyzed for single nucleotide polymorphisms in factor H (CFH), factor B-C2 (BF-C2) and complement C3 (C3) genes which were previously found to be associated with AMD. All activation products, especially markers of chronic complement activation Ba and C3d (pAMD patients compared to controls. Similar alterations were observed in factor D, but not in C3, C4 or factor H. Logistic regression analysis revealed better discriminative accuracy of a model that is based only on complement activation markers Ba, C3d and factor D compared to a model based on genetic markers of the complement system within our study population. In both the controls' and AMD patients' group, the protein markers of complement activation were correlated with CFH haplotypes.This study is the first to show systemic complement activation in AMD patients. This suggests that AMD is a systemic disease with local disease manifestation at the ageing macula. Furthermore, the data provide evidence for an association of systemic activation of the alternative complement pathway with genetic variants of CFH that were previously linked to AMD susceptibility.

    Full Text Available This article argues that an indigenous approach to communication research allows us to re-think academic approaches of engaging in and evaluating participatory communication research. It takes as its case study the Komuniti Tok Piksa project undertaken in the Highlands of Papua New Guinea. The project explores ways in which visual methods when paired with a community action approach embedded within an indigenous framework can be used to facilitate social change through meaningful participation. It involves communities to narrate their experiences in regard to HIV and AIDS and assists them in designing and recording their own messages. Local researchers are trained in using visual tools to facilitate this engagement with the communities.

    Activity cliffs have large impact in drug discovery; therefore, their detection and quantification are of major importance. This work introduces the metric activity cliff enrichment factor and expands the previously reported activity cliff generator concept by adding chemotype information to representations of the activity landscape. To exemplify these concepts, three molecular databases with multiple biological activities were characterized. Compounds in each database were grouped into chemotype classes. Then, pairwise comparisons of structure similarities and activity differences were calculated for each compound and used to construct chemotype-based structure-activity similarity (SAS) maps. Different landscape distributions among four major regions of the SAS maps were observed for different subsets of molecules grouped in chemotypes. Based on this observation, the activity cliff enrichment factor was calculated to numerically detect chemotypes enriched in activity cliffs. Several chemotype classes were detected having major proportion of activity cliffs than the entire database. In addition, some chemotype classes comprising compounds with smooth structure activity relationships (SAR) were detected. Finally, the activity cliff generator concept was applied to compounds grouped in chemotypes to extract valuable SAR information.

    2011-05-01

    Intensive repetitive musical practice can lead to bilateral cortical reorganization. However, whether musical sensorimotor and cognitive abilities transfer to nonmusical cognitive abilities that are maintained throughout the life span is unclear. In an attempt to identify modifiable lifestyle factors that may potentially enhance successful aging, we evaluated the association between musical instrumental participation and cognitive aging. Seventy older healthy adults (ages 60-83) varying in musical activity completed a comprehensive neuropsychological battery. The groups (nonmusicians, low and high activity musicians) were matched on age, education, history of physical exercise, while musicians were matched on age of instrumental acquisition and formal years of musical training. Musicians were classified in the low (1-9 years) or high (>10 years) activity group based on years of musical experience throughout their life span. The results of this preliminary study revealed that participants with at least 10 years of musical experience (high activity musicians) had better performance in nonverbal memory (η2 = .106), naming (η2 = .103), and executive processes (η2 = .131) in advanced age relative to nonmusicians. Several regression analyses evaluated how years of musical activity, age of acquisition, type of musical training, and other variables predicted cognitive performance. These correlational results suggest a strong predictive effect of high musical activity throughout the life span on preserved cognitive functioning in advanced age. A discussion of how musical participation may enhance cognitive aging is provided along with other alternative explanations.

    Climate change and human activities are the two kinds of driving forces in desertification,and assessing their relative role in desertification is of great significance to deeply understanding the driving mechanisms and preventing desertification expansion.This paper has systematically reviewed the progress of the researches on assessing the relative role of climate change and human activities in desertification from qualitative,semi-quantitative and quantitative aspects respectively.The authors found that there were still some problems in the previous researches.For example,the subjectivity in assessment was obvious,the assessment cannot be easily repeated,and the assessment and its results were always based on administrative regions and less taken and expressed in a continuous space.According to the progress of previous researches and the works conducted by the authors recently,we put forward a quantitative approach by selecting NPP as a common indicator to measure the relative role of climate change and human activities in desertification and dividing the ecological process of “driving force effect-dynamic response of desertified land” into several scenarios.Meanwhile,validation and scale of assessment should be taken into account when quantitative assessment of the relative role of climate change and human activities in desertification are carried out.

    Self-control refers to the capacity to override or alter a predominant response tendency. The current experiment tested the hypothesis that exercising self-control temporarily increases approach motivation, as revealed by patterns of electrical activity in the prefrontal cortex. Participants completed a writing task that did vs did not require them to exercise self-control. Then they viewed pictures known to evoke positive, negative or neutral affect. We assessed electroencephalographic (EEG) activity while participants viewed the pictures, and participants reported their trait levels of behavioral inhibition system (BIS) and behavioral activation system (BAS) sensitivity at the end of the study. We found that exercising (vs not exercising) self-control increased relative left frontal cortical activity during picture viewing, particularly among individuals with relatively higher BAS than BIS, and particularly during positive picture viewing. A similar but weaker pattern emerged during negative picture viewing. The results suggest that exercising self-control temporarily increases approach motivation, which may help to explain the aftereffects of self-control (i.e. ego depletion).

    The use of HVDC lines in electric power transmission is increasing all over the world. This exceptional increase is the result of the rapid technological development in AC/DC converter stations (power electronics) and of the advantage of HVDC over AC transmission on long distances, submarine connection by means of cables, interconnection of different electric systems, easy control of flowing power, etc. Consequently, also the research and testing activities in this field are under worldwide development. However, research activities imply huge investments and the involment of a lot of personnel. Cooperation agreements such as the one between CESI and CPRI could permit the combination of efforts and the optimization of the results. In this framework, and RandD cooperation programme is on going between the CPRI and CESI (Italy) research facilities. In this paper the facilities available at CESI for carrying out research and tests in the HVDC field are presented and outlines of some studies and tests, already performed, are given. Furthermore, a review of the joint research work which is being carried out by CESI and CPRI is reported.

    Healthy lifestyles such as being physically active and eating a healthy diet help reduce the childhood obesity risk. However, population-level studies on the relationship between lifestyles and childhood obesity typically focus on either physical activity or diet but seldom both. This study examined physical activity and diet quality in relation to obesity in a nationally representative sample of U.S. children and adolescents. The study sample of 2818 children 6-17 years old came from the National Health and Nutrition Examination Survey 2003-2006 waves. A healthy eating index (HEI)-2010 was constructed based on two nonconsecutive 24-h dietary recalls. Participants at or above the 60th percentile of the HEI-2010 score were classified as consuming a healthy diet. Participants engaging in at least 60 min of moderate-vigorous physical activity daily measured by accelerometer were classified as being physically active. Adjusted average marginal effect of diet quality and physical activity on obesity was calculated based on estimates from logistic regressions. Compared with those consuming a healthy diet who are physically active, the estimated probabilities for overweight and obesity were 19.03 (95% confidence interval: 11.31, 26.74) and 15.84 (10.48, 21.21) percentage points higher among children consuming an unhealthy diet and who are physically inactive, 16.53 (7.58, 25.48) and 13.48 (5.68, 21.29) percentage points higher among children consuming a healthy diet but who are physically inactive and 3.22 (-3.43, 9.88) and 3.10 (-3.08, 9.29) percentage points higher among children consuming an unhealthy diet but physically active, respectively. Healthy habit formation at an early age is essential in obesity prevention.

All modern firms either found public relations department in their body to deal with public relations operations or outsource this activity to consultants in order to communicate with target populations. Among the firms in tourism sector, hospitality companies are the ones that use public relations the most. The purpose of this study is to investigate the communication techniques in public relation and effects of these techniques on public relation activities. A literature review was conducted for research model and then questionnaire was developed from the studies in the literature. Data were collected by researchers in face-to-face interviews with 145 supervisors who are responsible for public relation activities of the hotel and were analyzed with SPSS statistical programs. Structural and convergent validity of the data have revealed with the explanatory factor analysis. It was tested using a regression analysis to determine the effects of independent variables on dependent variables. As a result, independent variables have positive effects on the dependent variables.

    Previous research suggests that, during visual search and discrimination tasks, older adults place greater emphasis than younger adults on top-down attention. This experiment investigated the relative contribution of target activation and distractor inhibition to this age difference. Younger and older adults performed a singleton discrimination task in which either an E or an R target (colour singleton) was present among distractor letters. Relative to a baseline condition in which the colours of the targets and distractors remained constant, an age-related slowing of performance was evident when either the colour of the target or that of the distractors varied across trials. The age-related slowing was more pronounced in response to target colour variation, suggesting that older adults place relatively greater emphasis on the top-down activation of target features.

    The activities described in this summary of the Accelerator and Fusion Research Division are diverse, yet united by a common theme: it is our purpose to explore technologically advanced techniques for the production, acceleration, or transport of high-energy beams. These beams may be the heavy ions of interest in nuclear science, medical research, and heavy-ion inertial-confinement fusion; they may be beams of deuterium and hydrogen atoms, used to heat and confine plasmas in magnetic fusion experiments; they may be ultrahigh-energy protons for the next high-energy hadron collider; or they may be high-brilliance, highly coherent, picosecond pulses of synchrotron radiation.

    2017-03-01

    Full Text Available In recent years, the study of the research capacity of the country and regions has become more active not only from the point of view of their leading components (personnel, financial, information, organizational, material-and-technical ones but also from the perspective of the assessment of productivity and effectiveness of researchers’ work. In the cross-country analysis, the certain highly aggregative parameters, which values, as a rule, are not in favour of Russia, are used. At the same time, at profound studying of this topic, these estimates cannot represent correctly the real trends of inventive activity in the scientific and technological sphere of the country and its regions. Moreover, the measurement of the researchers’ creative potential realization is carried out mainly through the assessment systems of their printing activity. Little attention is paid to the problem of the rating assessments of the researchers’ inventive and patent activity and its products from a cross-country perspective (especially to the detailed ones as well as to its institutional determinants. Therefore, the authors have chosen this subject-matter of the research. Its empirical basis is the statistical materials of both the national database and those which are recognized by the world scientific community. This research has both theoretical and methodological orientations. The purpose is the development of methodological and methodical tools of the research and assessment of researchers’ inventive activity including methodological support of cross-country comparative assessments. The authors have based the hypothesis on their previous research: in the conditions of the decreasing level of financial security, continuous reduction of a number of researchers, institutional restrictions and contradictions, the inventive activity of national researchers is still exist, and in a number of its leading parameters is implemented at the level of the advanced

    Full Text Available Abstract Background Children and adolescents are important target groups for prevention of overweight and obesity as overweight is often developed early in life and tracks into adulthood. Research into behaviors related to overweight (energy balance-related behaviors and the personal and environmental determinants of these behaviors is fundamental to inform prevention interventions. In the Netherlands and in other countries systematic research into environmental determinants of energy balance related behaviors in younger adolescents is largely lacking. This protocol paper describes the design, the components and the methods of the ENDORSE study (Environmental Determinants of Obesity in Rotterdam SchoolchildrEn, that aims to identify important individual and environmental determinants of behaviors related to overweight and obesity and the interactions between these determinants among adolescents. Methods The ENDORSE study is a longitudinal study with a two-year follow-up of a cohort of adolescents aged 12–15 years. Data will be collected at baseline (2005/2006 and at two years follow-up (2007/2008. Outcome measures are body mass index (BMI, waist circumference, time spent in physical activity and sedentary behaviors, and soft drink, snack and breakfast consumption. The ENDORSE study consists of two phases, first employing qualitative research methods to inform the development of a theoretical framework to examine important energy balance related behaviors and their determinants, and to inform questionnaire development. Subsequently, the hypothetical relationships between behavioral determinants, energy balance related behaviors and BMI will be tested in a quantitative study combining school-based surveys and measurements of anthropometrical characteristics at baseline and two-year follow-up. Discussion The ENDORSE project is a comprehensive longitudinal study that enables investigation of specific environmental and individual determinants of

  6. Resveratrol and novel potent activators of SIRT1: effects on aging and age-related diseases.

    Studies show that the plant polyphenol resveratrol can extend the life span of yeast, worms, flies, and fish. It also mitigates the metabolic dysfunction of mice fed high-fat diets. Resveratrol appears to mediate these effects partly by activating SIRT1, a deacetylase enzyme that regulates the activity of several transcriptional factors and enzymes responsive to nutrient availability. However, few foods contain resveratrol and humans metabolize it extensively, resulting in very low systemic bioavailability. Substantial research effort now focuses on identifying and testing more bioavailable and potent activators of SIRT1 for use as pharmacologic interventions in aging and age-related disorders.

    This paper is about methodological issues in a community-wide study in Nigeria on an infectious disease, namely HIV/AIDS. The study was designed to ascertain the risk factors that contribute to the spread of HIV/AIDS and how that can be tackled in order to bring about behavioural change. The research team believed at the onset that a study on the interplay between HIV/AIDS and sensitive issues like sexual mores and sexuality requires much more than a straightjacket social science method, such as simply doing a cross-section study and/or using interview schedule. This paper reviews the essence of cross-disciplinary approach; team building; as well as the use of a non-participatory observational approach in data collection. It also shows why ample consideration was given to ethical issues which are often glossed over in social research in developing countries. The lessons from the study underscore the methodological imperatives in social research that focus on sensitive issues in largely non-literate context like Nigeria. Although there are formidable challenges in community-based studies in largely non-literate societies, nevertheless they could easily be surmounted if there are ample time and resources to navigate the various sticking points.

    Government agencies and other authorities often communicate earthquake risks using maps derived from geographic information systems. Yet, little is known about the effects of these maps on risk perceptions. While mental models research and other approaches are available to inform risk communication text design, similar empirically derived guidance is lacking for visual risk communications, such as maps, which are likely to trump text in their impact and appeal. This paper reviews the empirical research that might inform such guidance. Research on graphs, spatial and visual perception, and map design suggests that graphics increase risk avoidance over numerical risk representations, and countable visuals, like dots, can increase the accuracy of perceived risks, but not always. Cartographic design features, such as color, animation, interactivity, and depth cues, are all candidates to represent risk and uncertainty and to influence risk perception. While there are robust known effects of color (e.g., red = danger), with some cultural variability, animation can increase the salience of otherwise obscure features but is not uniformly effective. Depth cues, dimensionality, and the extent to which a representation depicts versus symbolizes a scene will influence the viewer's perspective and perception, depending on the viewer's familiarity with the scene; their effects on risk perception remain unclear. The translation and representation of technical information about risk and uncertainty is critical to risk communication effectiveness. Our review suggests a handful of candidate criteria for evaluating the effects of risk visualizations, short of changes in behavior: accuracy, accessibility, retention, and perceived risk and usefulness.

    Full Text Available Objective: The main objective of the paper is to identify the use of Social Networking Sites (SNSs in job related activities and indicate the interdependencies between these activities and age, gender, as well as education in culturally diversified markets (China, Poland, Turkey, the United States. Research Design & Methods: In the exploratory empirical study the authors used two research methods: PAPI (Paper and Pen Personal Interview and CAWI (Computer Assisted Web Interview. The empirical data were collected in 2016 and the total number of respondents from four culturally diversified countries was 1246. Findings: The analysis with the use of Kruskal-Wallis and Dunn post-hoc tests showed that the Turkish respondents most often use SNSs for job related activities, while it is the least often done by the studied Americans. Moreover, from among the studied factors (gender, age and education level that differentiate the SNSs usage for job related activities in a statistically significant way age is of greatest importance. Implications & Recommendations: The results of the research provide implications for the recruitment policy of multinational enterprises (MNEs. Since more and more enterprises use SNSs in order to look for new employees and advertise themselves as employers (employer branding, the identified interdependencies between the SNSs activities and the analysed factors can support firm attempts to develop the proper recruitment policy taking into account the cultural diversity of potential workers. Contribution & Value Added: There are not many studies in the literature which present the usage of SNSs for job related activities from the perspective of individual users in the cross-cultural approach. The majority of studies are related to the usage of SNSs by enterprises in the recruitment process.

    Wang, Yuan-Chuen

    2014-01-01

    More than 50% of the world population is infected with Helicobacter pylori (H. pylori). The bacterium highly links to peptic ulcer diseases and duodenal ulcer, which was classified as a group I carcinogen in 1994 by the WHO. The pathogenesis of H. pylori is contributed by its virulence factors including urease, flagella, vacuolating cytotoxin A (VacA), cytotoxin-associated gene antigen (Cag A), and others. Of those virulence factors, VacA and CagA play the key roles. Infection with H. pylori vacA-positive strains can lead to vacuolation and apoptosis, whereas infection with cagA-positive strains might result in severe gastric inflammation and gastric cancer. Numerous medicinal plants have been reported for their anti-H. pylori activity, and the relevant active compounds including polyphenols, flavonoids, quinones, coumarins, terpenoids, and alkaloids have been studied. The anti-H. pylori action mechanisms, including inhibition of enzymatic (urease, DNA gyrase, dihydrofolate reductase, N-acetyltransferase, and myeloperoxidase) and adhesive activities, high redox potential, and hydrophilic/hydrophobic natures of compounds, have also been discussed in detail. H. pylori-induced gastric inflammation may progress to superficial gastritis, atrophic gastritis, and finally gastric cancer. Many natural products have anti-H. pylori-induced inflammation activity and the relevant mechanisms include suppression of nuclear factor-κB and mitogen-activated protein kinase pathway activation and inhibition of oxidative stress. Anti-H. pylori induced gastric inflammatory effects of plant products, including quercetin, apigenin, carotenoids-rich algae, tea product, garlic extract, apple peel polyphenol, and finger-root extract, have been documented. In conclusion, many medicinal plant products possess anti-H. pylori activity as well as an anti-H. pylori-induced gastric inflammatory effect. Those plant products have showed great potential as pharmaceutical candidates for H. pylori

    Research plays a critical role throughout virtually every conduit of the health services industry. The key terms of research, public relations, and organizational interests are discussed. Combining public relations as a strategic methodology with the organizational concern as a factor, a typology of four different research methods emerges. These four health marketing research methods are: investigative, strategic, informative, and verification. The implications of these distinct and contrasting research methods are examined.

    2008-01-01

    This article argues for the confirmation of Marxist philosophy as the ideology that guides international relations (IR) studies in China.Justification comes through the following points. According to Marxism,correct theoretical guidance serves as the prerequisite for correct practice.Marxist philosophy embodies, by nature, righteousness, in opposition to political hegemony. Accordingly, practice under its guidance represents fruitful revolutionary realism. Finally, advanced studies of international relations in this country cannot be separated from philosophical thinking.Using these arguments as background, this article specifically advocates materialism, patriotism, and service to the people as the corner-stone of China's IR theory building.

  19. The temporal dynamics of metacognition: Dissociating task-related activity from later metacognitive processes.

    2016-02-01

    In recent years, neuroscience research spent much effort in revealing brain activity related to metacognition. Despite this endeavor, it remains unclear exactly when metacognitive experiences develop during task performance. To investigate this, the current study used EEG to temporally and spatially dissociate task-related activity from metacognitive activity. In a masked priming paradigm, metacognitive experiences of difficulty were induced by manipulating congruency between prime and target. As expected, participants more frequently rated incongruent trials as difficult and congruent trials as easy, while being completely unable to perceive the masked primes. Results showed that both the N2 and the P3 ERP components were modulated by congruency, but that only the P3 modulation interacted with metacognitive experiences. Single-trial analysis additionally showed that the magnitude of the P3 modulation by congruency accurately predicted the metacognitive response. Source localization indicated that the N2 task-related activity originated in the ACC, whereas the P3-interplay between task-related activation and metacognitive experiences originated from the precuneus. We conclude that task-related activity can be dissociated from later metacognitive processing. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2014-01-01

    The management of research data is now a major challenge for research organisations. Vast quantities of born-digital data are being produced in a wide variety of forms at a rapid rate in universities. This paper analyses the contribution of academic libraries to research data management (RDM) in the wider institutional context. In particular it: examines the roles and relationships involved in RDM, identifies the main components of an RDM programme, evaluates the major drivers for RDM activities, and analyses the key factors influencing the shape of RDM developments. The study is written from the perspective of library professionals, analysing data from 26 semi-structured interviews of library staff from different UK institutions. This is an early qualitative contribution to the topic complementing existing quantitative and case study approaches. Results show that although libraries are playing a significant role in RDM, there is uncertainty and variation in the relationship with other stakeholders such as IT services and research support offices. Current emphases in RDM programmes are on developments of policies and guidelines, with some early work on technology infrastructures and support services. Drivers for developments include storage, security, quality, compliance, preservation, and sharing with libraries associated most closely with the last three. The paper also highlights a 'jurisdictional' driver in which libraries are claiming a role in this space. A wide range of factors, including governance, resourcing and skills, are identified as influencing ongoing developments. From the analysis, a model is constructed designed to capture the main aspects of an institutional RDM programme. This model helps to clarify the different issues involved in RDM, identifying layers of activity, multiple stakeholders and drivers, and a large number of factors influencing the implementation of any initiative. Institutions may usefully benchmark their activities against the

    Full Text Available Introduction: There are five Bulgarian medical universities in the cities of Sofia, Plovdiv, Varna, Pleven and Stara Zagora. A major priority of medical universities is to encourage research activities mainly aimed at preparation and implementation of research projects. Projects are managed by the participating organizations called “beneficiaries”. Beneficiaries develop projects, apply for finances and if approved they implement those projects.Aim: The purpose of our study is to examine the organizational structure of research project activities on the macro level and on the micro level in Bulgarian medical universities.Material and methods: In order to define the separate elements of the organizational structure and to analyze the relations and interaction between them we have applied a documentary and sociological approach. Results: During the last six years there was a significant increase in the number and the overall annual financial value of the projects performed at medical universities in Bulgaria. The reasons for such increase are: managers realizing the advantages of and benefits from the implementation of research projects ensuring high quality modernization of research units’ equipment and facilities; access to innovative technologies; development of interdisciplinary relations, etc. Benefits arising from improved results motivate us to consider as appropriate some additional investments aimed at increasing the number of team members and further optimization of the currently existing structures (research centers in charge of research with the purpose of achieving even better results in this particular field. Conclusion: The role of research project activities in medical universities’ research field is of vital importance for the educational institutions’ success. Taking into consideration the changed conditions, European possibilities and the highly competitive environment, realizing this aspect will be essential for the

However, research methodology and theory...... of science if often not favored subjects by engineering students, who tend to find the subjects abstract. Thus, the students are often very engaged in the subjects, nor are textbooks or teaching very engaging. This poster asks how we can promote active learning in research methodology and theory of science......? Based on a pragmatic reading of Batesons logical categories of learning, the poster suggests a conceptual framework for competence development in research methodology and theory of science, which identify different sets of competencies (instrumental, practical, analytical and critical) as well...

    The technology and application of current accelerometer-based devices in physical activity (PA) research allow the capture and storage or transmission of large volumes of raw acceleration signal data. These rich data not only provide opportunities to improve PA characterisation, but also bring logistical and analytic challenges. We discuss how researchers and developers from multiple disciplines are responding to the analytic challenges and how advances in data storage, transmission and big data computing will minimise logistical challenges. These new approaches also bring the need for several paradigm shifts for PA researchers, including a shift from count-based approaches and regression calibrations for PA energy expenditure (PAEE) estimation to activity characterisation and EE estimation based on features extracted from raw acceleration signals. Furthermore, a collaborative approach towards analytic methods is proposed to facilitate PA research, which requires a shift away from multiple independent calibration studies. Finally, we make the case for a distinction between PA represented by accelerometer-based devices and PA assessed by self-report.

    Full Text Available In this era that we live in there are such personality structures that we call ‘narcissism’ which is based on the Greek Mythology as the person who sees there is own reflection on the water and from this reflection he falls in love, in other words falls in love with oneself and throughout his life strives to find this love that can never reached. Narcissism is sepearted into two as being normal and pathological. The biggest help in understanding narcissism comes from the psychoanalytical theroies of objcet consistency and theory of self but the importance and severity of the disorder was stated in the DSM-III (Ozan ve ark., 1980. There are many research taken place on Narcissism and many measurements enabled in this research. There are dynamically orientated with projective tests and descriptive orientated objective tests among these studies. This article’s aim is to discuss Narcissism’s development process from the first time when it was found until today with interesting findings.

    Full Text Available Folksonomies are a decentralized yet collaborative form of classification based on user-defined keywords (also known as tags. Although this uncontrolled method of classification lacks rules for term standardization and usage, it has potential for organizational patterns and an emerging vocabulary (terminology. The objective of this research is to analyze the descriptors and tags from journal articles indexed in the Education Resources Information Center (ERIC and the folksonomy-based website CiteULike to determine overlap between the controlled and uncontrolled vocabularies. Metadata from 2,786 journal articles indexed in ERIC and CiteULike was collected using Perl and MySQL. The total metadata was comprised of 2,899 unique ERIC descriptors, 3,176 unique CiteULike tags, and 1,083 unique CiteULike users. An analysis of this metadata revealed that 240 of the CiteULike tags matched ERIC descriptors. The low number of tag-descriptor matches in this research indicates that CiteULike users do not use the same terminology as subject specialists who maintain descriptors in the ERIC thesaurus.

  13. Call 4 Concern: patient and relative activated critical care outreach.

    Odell, Mandy; Gerber, Karin; Gager, Melanie

    Patients can experience unexpected deterioration in their physiological condition that can lead to critical illness, cardiac arrest, admission to the intensive care unit and death. While ward staff can identify deterioration through monitoring physiological signs, these signs can be missed, interpreted incorrectly or mismanaged. Rapid response systems using early warning scores can fail if staff do not follow protocols or do not notice or manage deterioration adequately. Nurses often notice deterioration intuitively because of their knowledge of individual patients. Patients and their relatives have the greatest knowledge of patients, and can often pick up subtle signs physiological deterioration before this is identified by staff or monitoring systems. However, this ability has been largely overlooked. Call 4 Concern (C4C) is a scheme where patients and relatives can call critical care teams directly if they are concerned about a patient's condition- it is believed to be the first of its kind in the UK. A C4C feasibility project ran for six months, covering patients being transferred from the intensive care unit to general wards. C4C has the potential to prevent clinical deterioration and is valued by patients and relatives. Concerns of ward staff could be managed through project management. As it is relatively new, this field offers further opportunities for research.

    Full Text Available The South African prevention of mother to child transmission programme has made excellentprogress in reducing vertical HIV transmission, and paediatric antiretroviral therapyprogrammes have demonstrated good outcomes with increasing treatment initiation inyounger children and infants. However, both in South Africa and across sub-Saharan African,lack of boosted peri-partum prophylaxis for high-risk vertical transmission, loss to followup,and failure to initiate HIV-infected infants on antiretroviral therapy (ART before diseaseprogression are key remaining gaps in neonatal HIV-related care. In this issue of the Southern African Journal of HIV Medicine, experts provide valuable recommendations for addressingthese gaps. The present article highlights a number of areas where evidence is lacking toinform guidelines and programme development for optimal neonatal HIV-related care.

    We screened the major bioactive flavones isolated from Scutellaria baicalensis (baicalin, baicalein and oroxylin A) for their convulsion related activities. In electrogenic response score system and the pentylenetetrazole seizure model, baicalein but not oroxylin A and baicalin exhibited anticonvulsant effects. In vitro studies also revealed that baicalein induced intracellular Cl(-) influx, whereas oroxylin A blocked muscimol- and baicalein-induced intracellular Cl(-) influx. The anticonvulsant effect of baicalein was inhibited by flumazenil, a benzodiazepine(BZD) receptor antagonist. Therefore, anticonvulsive effect of baicalein was mediated by the BZD binding site of GABA(A) receptor. The 5, 7-dihydroxyl group is present in the structure of the three flavones. It is postulated that this group played a key role in inducing convulsion-related activities.

    2002-01-01

    Age-related macular degeneration (AMD) is the most frequent cause of severe vision loss in older persons and is associated with high rates of disability and depression. The authors evaluated 51 patients with bilateral AMD to investigate the interrelationships of disease severity, disability, and depression and focused on loss of valued activities as an emblematic disabling consequence of AMD. They characterized depression by the Center for Epidemiologic Studies-Depression (CES-D) score, a syndromal state based on the CES-D, and as a level of distress (Index of Affective Suffering; IAS). Thirty subjects (58.8%) had loss of a valued, discretionary activity. They had worse visual acuity and more depressive symptoms and were represented in higher IAS levels than other subjects. Visual acuity was significantly correlated with IAS levels, but not with CES-D scores or syndromal depression. A regression model demonstrated that activity loss mediated the relationship between visual acuity and IAS level. Affective distress occurs in AMD, largely to the extent that valued activities are relinquished because of vision loss. IAS levels best illuminated this relationship, suggesting the value of this dimension of affective functioning in studies of the consequences of chronic disease.

    2007-01-01

    Full Text Available Abstract Background Canadian funding agencies are no longer content to support research that solely advances scientific knowledge, and key directives are now in place to promote research transfer to policy- and decision-makers. Therefore, it is necessary to improve our understanding of how researchers are trained and supported to facilitate knowledge translation activities. In this study, we investigated differences in health researcher characteristics and knowledge translation activities. Methods Our sample consisted of 240 health researchers from three Alberta universities. Respondents were classified by research domain [basic (n = 72 or applied (n = 168] and faculty [medical school (n = 128 or other health science (n = 112]. We examined our findings using Mode I and Mode II archetypes of knowledge production, which allowed us to consider the scholarly and social contexts of knowledge production and translation. Results Differences among health researcher professional characteristics were not statistically significant. There was a significant gender difference in the applied researcher faculty group, which was predominantly female (p p p = .01; Mode II, p p = .025 and number of publications (medical school > other faculties; p = .004. There was an interaction effect for research domain and faculty group for number of publications (p = .01, in that applied researchers in medical faculties published more than their peers in other faculty groups. Conclusion Our findings illustrate important differences between health researchers and provide beginning insights into their professional characteristics and engagement in Mode I and Mode II activities. A future study designed to examine these dimensions in greater detail, including potential covariates across more varied institutions, would yield richer insights and enable an examination of relative influences, needs and costs of each mode of activity.

  18. Towards age/rotation/magnetic activity relation with seismology

    2015-01-01

    Full Text Available The knowledge of stellar ages directly impacts the characterization of a planetary system as it puts strong constraints on the moment when the system was born. Unfortunately, the determination of precise stellar ages is a very difficult task. Different methods can be used to do so (based on isochrones or chemical element abundances but they usually provide large uncertainties. During its evolution a star goes through processes leading to loss of angular momentum but also changes in its magnetic activity. Building rotation, magnetic, age relations would be an asset to infer stellar ages model independently. Several attempts to build empirical relations between rotation and age (namely gyrochronology were made with a focus on cluster stars where the age determination is easier and for young stars on the main sequence. For field stars, we can now take advantage of high-precision photometric observations where we can perform asteroseismic analyses to improve the accuracy of stellar ages. Furthermore, the variability in the light curves allow us to put strong constraints on the stellar rotation and magnetic activity. By combining these precise measurements, we are on the way of understanding and improving relations between magnetic activity, rotation, and age, in particular at different stages of stellar evolution. I will review the status on gyrochronology relationships based on observations of young cluster stars. Then I will focus on solar-like stars and describe the inferences on stellar ages, rotation, and magnetism that can be provided by high-quality photometric observations such as the ones of the Kepler mission, in particular through asteroseismic analyses.

  19. Researching in Execution Modes for Concurrent Active Rules

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    It is known as Coupling Modes that how the rule in active database system is triggered to execute by rule monitor when some special events occurs. In general, the Coupling Modes may be divided into immediate, deferred and detached modes in active database systems. This paper classifies the coupling modes into syn-coupling and asyn-coupling modes, according to the key issue, synchrony/asynchrony, in parallel programming language. Rule execution semantics for various coupling modes is distinctly defined. It is beneficial to implementation and usage of the active rule system. After graph-based rule system (E-RG) and its execution model, which have been researched in their previous works, are chiefly described, the authors show the various strategies to construct the syn-coupling and asyn-coupling modes in E-RG rule system, based on semantics for coupling modes.

    While the United States research program for geologic disposal of high-level radioactive waste over the past decades focused solely on an open tunnel emplacement in unsaturated densely fractured tuff, several international organizations have made significant progress in the characterization and performance evaluation of other disposal design options and host rock characteristics, most of which were very different from those studied in the U.S. As a result, areas of direct collaboration between the U.S. Department of Energy’s (DOE) and international geologic disposal programs were quite limited during that time. Recently, the decision by DOE to no longer pursue the geologic disposal of high-level radioactive waste and spent fuel at the Yucca Mountain site has shifted the nation’s focus to disposal design options and geologic environments similar to those being investigated by other nations. DOE started to recognize that close international collaboration is a beneficial and costeffective strategy for advancing disposal science and, in FY12, embarked on a comprehensive effort to identify international collaboration opportunities, to interact with international organizations and advance promising collaborations, and to plan/develop specific R&D activities in cooperation with international partners. This report describes the active collaboration opportunities available to U.S. researchers as a result of this effort, and presents specific cooperative research activities that have been recently initiated within DOE’s disposal research program. The focus in this report is on those opportunities that provide access to field data (and respective interpretation/modeling), and/or may allow participation in ongoing and planned field experiments.

  5. Research on the Characteristics of Large Earthquake Activity on the Active Tectonic Boundaries on the Chinese Mainland

    2006-01-01

    Based on the research and the division of the active tectonic blocks and their boundaries on the Chinese mainland, the feature of the large earthquake activities on the 24 boundaries between the 6 active tectonic block regions (grade Ⅰ ) and the 22 active tectonic blocks (grade Ⅱ ) are studied. The seismicity levels on the active tectonic block boundaries are discussed considering the large earthquake frequency and the released strain energy in unit distance and time. The theoretic maximal magnitude and the recurrence period of each boundary are then calculated from the G-R relation. By comparing this with the actual earthquake records, it is found that the intensities of the earthquake deduced from the seismic activity parameter (a/b) on the main active boundaries on the Chinese mainland are consistent with that of the natural earthquakes. Meanwhile, an inverse relation is found between the recurrence periods of large earthquakes and the tectonic motion rate on the boundaries. These results show that the a, b values of each boundary obtained in this paper are valuable. In addition, the present seismic activities and hazards of these boundaries are also probed into with the historical data and their elapsed time on each boundary based on the hypothesis that the large earthquakes satisfy Poisson distribution.

    Nuclear industry pays a particular attention to structures integrity problems: well-aware of the possible catastrophic consequence of a major accident, everything is carried out to minimise the risk of such a situation. From the design, and during all the operating life of the plant, a high level of safety is required and checks by the safety authorities, on the basis of reports made by the operator. These two entities ask for R and D activities to support the improvement of the knowledge of the phenomena already identified (as in the case of the vessel of the PWR) or to bring some element of understanding to situation not considered yet, up to the first incident (as in 1998 with the fatigue problems in the thermal mixing zone, at the origin of the Civaux arrest). Among the CEA teams concerned with these problems, the Laboratory of the Structures Integrity and of Normalisation aims to study the integrity problems in metallic nuclear structures leaning on exceptional experimental means: the RESEDA platform allows the realisation of large-scaled tests on analytical tests (representative of analysed phenomena) to reproduce the industrial situation, linked to various and accurate equipment for the measures and the analyses. Three industrial thematics represent to main part of my research activities at CEA in the fracture mechanics field: - the industrial case of the PWR vessel is related to brittle fracture of the ferritic steels, - the piping components, related to ductile tearing and fracture in the brittle-to-ductile domain, - the high temperature fracture mechanics for the components submitted to very complex loadings.

    Obesity is a global health concern and has a great impact on countries in the Asia-Pacific region. Physical inactivity is a major risk factor for obesity, but physical activity levels are declining in much of this region. Increasing physical activity is a priority in many countries. Considerable research has been conducted on physical activity related to obesity in Western countries, but populations in the Asia-Pacific region differ in physical, psychological, social, and cultural ways that warrant local and regional research. The authors reviewed research conducted in the Asia-Pacific region that examined either the impact of physical activity interventions on obesity-related outcomes or the effect of behavior-change interventions on physical activity participation. The number of studies found was limited, and their samples and methods varied too much to draw conclusions. The authors recommend further research in the Asia-Pacific region using systematic protocols to permit sound conclusions to be drawn and promote informed action at local levels.

    Patients with unresponsive wakefulness syndrome (UWS) or in minimally conscious state (MCS) after brain injury show significant fluctuations in their behavioural abilities over time. As the importance of event-related potentials (ERPs) in the detection of traces of consciousness increases, we investigated the retest reliability of ERPs with repeated tests at four different time points. Twelve healthy controls and 12 inpatients (8 UWS, 4 MCS; 6 traumatic, 6 non-traumatic) were tested twice a day (morning, afternoon) for 2 days with an auditory oddball task. ERPs were recorded with a 256-channel-EEG system, and correlated with behavioural test scores in the Coma Recovery Scale-revised (CRS-R). The number of identifiable P300 responses varied between zero and four in both groups. Reliabilities varied between Krippendorff's α = 0.43 for within-day comparison, and α = 0.25 for between-day comparison in the patient group. Retest reliability was strong for the CRS-R scores for all comparisons (α = 0.83-0.95). The stability of auditory information processing in patients with disorders of consciousness is the basis for other, even more demanding tasks and cognitive potentials. The relatively low ERP-retest reliability suggests that it is necessary to perform repeated tests, especially when probing for consciousness with ERPs. A single negative ERP test result may be mistaken for proof that a UWS patient truly is unresponsive.

    Alcohol dependence is characterized as a multi-factorial disorder caused by a complex interaction between genetic and environmental liabilities across development. A variety of neurocognitive deficits/dysfunctions involving impairments in different brain regions and/or neural circuitries have been associated with chronic alcoholism, as well as with a predisposition to develop alcoholism. Several neurobiological and neurobehavioral approaches and methods of analyses have been used to understand the nature of these neurocognitive impairments/deficits in alcoholism. In the present review, we have examined relatively novel methods of analyses of the brain signals that are collectively referred to as event-related oscillations (EROs) and show promise to further our understanding of human brain dynamics while performing various tasks. These new measures of dynamic brain processes have exquisite temporal resolution and allow the study of neural networks underlying responses to sensory and cognitive events, thus providing a closer link to the physiology underlying them. Here, we have reviewed EROs in the study of alcoholism, their usefulness in understanding dynamical brain functions/dysfunctions associated with alcoholism as well as their utility as effective endophenotypes to identify and understand genes associated with both brain oscillations and alcoholism.

    The utilization of medicines to treat HIV-infected children has been promoting a decrease in the prevalence of soft-tissue oral lesions, as years pass by. In contrast, it has been observed that the experience of caries and gingivitis is constant in this population, mostly because of the chronic influence of some factors involved in the HIV-infection process, such as the chronic utilization of sweetened liquid medicines and carbohydrate-enriched diet, as well as frequent episodes of hospitalization. So, the purpose of this study was to evaluate if the quality and quantity of biofilm are important factors in the activity of dental caries and gingivitis, also in this special group. After examination of the biofilm (biofilm index - Ribeiro23, 2000), the activity of caries and gingivitis was assessed in 56 children, aging from 0 to 14 years, who were patients with definitive diagnosis of HIV infection. It was observed that only 7 subjects (12.5%) did not present with clinically visible biofilm, and 33 (58.9%) presented with gingivitis, with the average of 4.44 bleeding sites. As to dental caries, 73.2% of the patients presented with active carious lesions. A strong correlation was verified between Biofilm Index, gingival status and active carious lesions (Spearman's correlation test, r s = +0.57 and r s = +0.49, respectively). It was concluded that, also in HIV-infected children, the quality and quantity of biofilm over the dental surfaces are important etiologic factors related to the activity of caries and gingivitis. Biofilm should, thus, be controlled in order to reestablish the oral health of HIV-infected children.

    Emissions of CO2 from the energy and land-use change and forestry sectors are responsible for the majority of emissions in non-Annex I Parties to the UNFCCC. Tackling greenhouse gas (GHG) emissions from these sectors is a key to slowing the growth in GHG emissions in non-Annex I countries. Implementing Clean Development Mechanism (CDM) projects can help achieve this aim, while also assisting non-Annex I countries to move towards sustainable development and Annex I countries achieve their emission commitments under the Kyoto Protocol. There has been rapid progress in the CDM over the last year - in terms of the number of projects in the pipeline and registered, and in terms of credits issued. However, some important sectors are notable by their small share in the CDM portfolio. Several countries have also called attention to the need to accelerate the process of approving CDM methodologies and projects. In order to improve the effectiveness of the CDM to achieve its dual objectives, the COP/MOP agreed a decision on 'further guidance relating to the clean development mechanism. This decision lays out guidance on how to improve the operation of the CDM, and includes provisions that allow: (1) Bundling of project activities; and (2) Project activities under a programme of activities, to be registered as a CDM project activity. At present, of the 172 currently registered CDM project activities, 27 involve programmes or bundles. These project activities can include more than one project type, be implemented in several locations, and/or occur in more than one sector. This paper assesses how project activities under a programme of activities under the CDM (referred to here as PCDM) could help to increase the effectiveness of the CDM by encouraging a wide spread of emission mitigation activities. This paper also explores the key issues that may need to be considered for the PCDM concept to be further implemented. The paper concludes that: (1) Key concepts and issues

    Full Text Available Background: Tobacco smoking continues to be a major preventable cause of death and disease and therefore tobacco control research is extremely important. However, research in this area is often hampered by a lack in funding and there is a need for scientometric techniques to display research efforts. Methods: The present study combines classical bibliometric tools with novel scientometric and visualizing techniques in order to analyse and categorise research in the field of tobacco control. Results: All studies related to tobacco control and listed in the ISI database since 1900 were identified by the use of defined search terms.Using bibliometric approaches, a continuous increase in qualitative markers such as collaboration numbers or citations were found for tobacco control research. The combination with density equalizing mapping revealed a distinct global pattern of research productivity and citation activity. Radar chart techniques were used to visualize bi- and multilateral research cooperation and institutional cooperation. Conclusions: The present study supplies a first scientometricapproach that visualises research activity in the field of tobacco control. It provides data that can be used for funding policy and the identification of research clusters.

    To gain insights into the neural basis of such adaptive decision-making processes, we investigated the nature of learning process in humans playing a competitive game with binary choices, using a matching pennies game. As in reinforcement learning, the subject's choice during a competitive game was biased by its choice and reward history, as well as by the strategies of its opponent. Analyses of ERP data focused on the feedback-related negativity (FRN), we found that the magnitude of ERPs after losing to the computer opponent predicted whether subjects would change decision behavior on the subsequent trial. These findings provide novel evidence that humans engage a reinforcement learning process to adjust representations of competing decision options.

    Full Text Available Abstract Background The benefits of a recommended level of physical activity on physiological health indicators such as morbidity and mortality are well-accepted, but less research has addressed whether or not the association between the recommended level of physical activity and a health-related quality of life (HRQOL exists in the Japanese population. Thus, the present study examined whether the recommended physical activity would be associated with HRQOL in the general Japanese middle-aged population. Methods Data were obtained from 1211 male and female respondents (39.4 ± 10.9 year, mean ± SD from an Internet-based survey of registrants of an Internet research service. Physical activity level was estimated from the short form of the International Physical Activity Questionnaire. HRQOL was assessed with the Medical Outcomes Survey Short Form-8 questionnaire (SF-8. Based on the current national guidelines for exercise in Japan, respondents were divided into a recommended group, an insufficient group, and an inactive group according to their estimated weekly physical activity level. Multivariate analyses of covariance were utilized. Results Across both genders, the recommended group had significantly higher physical functioning (PF scores than the inactive group (p Conclusion Individuals who attained the recommended level of physical activity had better scores on some dimensions of HRQOL than those who did not, suggesting that the recommended level of physical activity may be applicable not only to the physiological objective outcomes but also to some dimensions in both the physical and mental aspects of HRQOL.

    Previous work has shown differential amygdala response to African-American faces by Caucasian individuals. Furthermore, behavioral studies have demonstrated the existence of skin tone bias, the tendency to prefer light skin to dark skin. In the present study, we used functional magnetic resonance imaging (fMRI) to investigate whether skin tone bias moderates differential race-related amygdala activity. Eleven White participants viewed photographs of unfamiliar Black and White faces with varied skin tone (light, dark). Replicating past research, greater amygdala activity was observed for Black faces than White faces. Furthermore, dark-skinned targets elicited more amygdala activity than light-skinned targets. However, these results were qualified by a significant interaction between race and skin tone, such that amygdala activity was observed at equivalent levels for light- and dark-skinned Black targets, but dark-skinned White targets elicited greater amygdala activity than light-skinned White targets.

    Full Text Available The article is devoted to methodological aspects of analysis of confrontation between two biggest trends in Islam - Sunnism and Shiism. It’s extremely important to study Sunni-Shiite relations on the modern stage because they reflect geopolitical and geostrategic rivalry in the region and change of interstate alliances’ configuration. After “the Arab spring” in the Middle East some conflicts have flared up (Iraq, Syria, Yemen, and one of the reasons of all the conflicts is a confrontation between Sunnis and Shiites. Moreover, some more hot spots are brewing, in which the representatives of two major trends in Islam will face (Lebanon, Saudi Arabia, Bahrain. In order to find ways to settle these conflicts we need to learn profoundly the origins, nature and characteristics of Sunni-Shiite relations, and it also determines the relevance of this article’s topic. Using comparative method, historicism, problem-chronological method and quantitative methods of analysis, the author indicates six periods of Sunni-Shiite antagonism, during which the contradictions between two trends had gradually shifted from domestic to international level, and then to global level. Comparing foreign policy practice of Sunni and Shiite states at the present stage, the author proves that nowadays the struggle between Sunnis and Shiites for the implementation of models of the Islamic world’s development takes place. These models are global, they are aimed at the unification of the Islamic world. However they are based on completely different visions of this world’s configuration, particularly in the region of the Middle East.

  20. The Radio Activity-Rotation Relation of Ultracool Dwarfs

    2011-01-01

    [Abridged] We present a new radio survey of about 100 late-M and L dwarfs undertaken with the VLA. The sample was chosen to explore the role of rotation in the radio activity of ultracool dwarfs. Combining the new sample with results from our previous studies and from the literature, we compile the largest sample to date of ultracool dwarfs with radio observations and measured rotation velocities (167 objects). In the spectral type range M0-M6 we find a radio activity-rotation relation, with saturation at log(L_rad/L_bol) 10^(-7.5) above vsini~5 km/s, similar to the relation in H-alpha and X-rays. However, at spectral types >M7 the ratio of radio to bolometric luminosity increases regardless of rotation velocity, and the scatter in radio luminosity increases. In particular, while the most rapid rotators (vsini>20 km/s) exhibit "super-saturation" in X-rays and H-alpha, this effect is not seen in the radio. We also find that ultracool dwarfs with vsini>20 km/s have a higher radio detection fraction by about a f...

    Greater physical activity and cardiorespiratory fitness are associated with reduced age-related cognitive decline and lower risk for dementia. However, significant gaps remain in the understanding of how physical activity and fitness protect the brain from adverse effects of brain aging. The primary goal of the current study was to empirically evaluate the independent relationships between physical activity and fitness with functional brain health among healthy older adults, as measured by the functional connectivity of cognitively and clinically relevant resting state networks. To build context for fitness and physical activity associations in older adults, we first demonstrate that young adults have greater within-network functional connectivity across a broad range of cortical association networks. Based on these results and previous research, we predicted that individual differences in fitness and physical activity would be most strongly associated with functional integrity of the networks most sensitive to aging. Consistent with this prediction, and extending on previous research, we showed that cardiorespiratory fitness has a positive relationship with functional connectivity of several cortical networks associated with age-related decline, and effects were strongest in the default mode network (DMN). Furthermore, our results suggest that the positive association of fitness with brain function can occur independent of habitual physical activity. Overall, our findings provide further support that cardiorespiratory fitness is an important factor in moderating the adverse effects of aging on cognitively and clinically relevant functional brain networks.

    2010-09-01

    Heartwater, a tick-borne disease caused by Ehrlichia ruminantium, is considered to be a significant cause of mortality amongst domestic and wild ruminants in South Africa. The main vector is Amblyomma hebraeum and although previous epidemiological studies have outlined endemic areas based on mortalities, these have been limited by diagnostic methods which relied mainly on positive brain smears. The indirect fluorescent antibody test (IFA) has a low specificity for heartwater organisms as it cross-reacts with some other species. Since the advent of biotechnology and genomics, molecular epidemiology has evolved using the methodology of traditional epidemiology coupled with the new molecular techniques. A new quantitative real-time polymerase chain reaction (qPCR) test has been developed for rapid and accurate diagnosis of heartwater in the live animal. This method can also be used to survey populations of A. hebraeum ticks for heartwater. Sampling whole blood and ticks for this qPCR differs from routine serum sampling, which is used for many serological tests. Veterinary field staff, particularly animal health technicians, are involved in surveillance and monitoring of controlled and other diseases of animals in South Africa. However, it was found that the sampling of whole blood was not done correctly, probably because it is a new sampling technique specific for new technology, where the heartwater organism is much more labile than the serum antibodies required for other tests. This qPCR technique is highly sensitive and can diagnose heartwater in the living animal within 2 hours, in time to treat it. Poor sampling techniques that decrease the sensitivity of the test will, however, result in a false negative diagnosis. This paper describes the development of a skills training programme for para-veterinary field staff, to facilitate research into the molecular epidemiology of heartwater in ruminants and eliminate any sampling bias due to collection errors.

    Full Text Available The aim of this study is to determine whether regular physical activity during early puberty is influential in preventing early menarche. This cross sectional study was carried out on 102 post-menarcheal girls aged 11–20 (14.79±0.33. 51 of them were already engaged in competitive sport activities prior to the onset of menstruation (group 1, while the others got engaged in such activities after the onset of menstruation (group 2. All participants provided the year and the month of their first menstrual period. First, we estimated the equality of dispersion between the two groups, by conducting Two Samples for Variances F-test. Second, because no homogeneity of variances between groups was found, they were compared by using Two Samples Assuming Unequal Variances t-test. The difference between groups is statistically significant, as the t statistics (=2.883 is greater than both critical t statistics (one-tail=1.664 two-tail=1.990 and the p value less than 0.05 in both cases (one-tail=0.002 two-tail=0.005. None of the girls in the first group starts to menstruate before 11 years of age and 90% of them are menstruating by age 14, with a median age of 12.95±0.35 years. Age of menarche is lower in the second group with a median age of 12.25±0.31 years, thus approximately 8 months lower than median age for the first group. 11.76% of the girls in the second group start to menstruate before 11 years of age and 90% of them are menstruating by age 13. It is rather, the decline in early matures among those engaged in regular physical activity prior to the onset of menses, that makes the statistically significant correlation between physical activity and age at menarche practically meaningful. Relatively early matures (<11 years have been found to be slightly shorter but up to 5.5 kg heavier in adulthood than are late matures. In addition, a relatively young age at menarche has been associated with an increased risk for breast cancer and spontaneous

    Full Text Available The study of political activism has grown significantly within the last fifty years. Political participation was always the cornerstone of research in political science, but the advent of comparative political behavior studies and quantitative analysis has paved the way for data-driven investigations of who votes, why people participate and what types of political activities citizens prefer. This article is an introduction to the main scholarship in political participation studies, its evolution since the beginning, the shift in focus from conventional activism to unconventional engagement, up to the most recent innovation of digital participation. The political behavior field has showed how citizens are not necessarily prepared to be polit-ical animals, how political interest and opportunities play a role in the levels of participation recorded and how individuals may choose newer, confrontational modes of political expression that better fit their needs. In the end, the entire development of this field of research highlights once more the relevance of political action, especially with regards to how participation has changed in Europe, over time and across borders.

    To further understand documented associations between obesity and urban sprawl, this research describes individuals' trade-offs between health-related activities and commuting time. A cross-section of 24,861 working-age individuals employed full-time and residing in urban counties is constructed from the American Time Use Survey (2003-2010). Data are analyzed using seemingly unrelated regressions to quantify health-related activity decreases in response to additional time spent commuting. Outcomes are total daily minutes spent in physical activity at a moderate or greater intensity, preparing food, eating meals with family, and sleeping. Commuting time is measured as all travel time between home and work and vice versa. The mean commuting time is 62 min daily, the median is 55 min, and 10.1% of workers commute 120 min or more. Spending an additional 60 min daily commuting above average is associated with a 6% decrease in aggregate health-related activities and spending an additional 120 min is associated with a 12% decrease. The greatest percentage of commuting time comes from sleeping time reductions (28-35%). Additionally, larger proportions of commuting time are taken from physical activity and food preparation relative to the mean commuting length: of 60 min spent commuting, 16.1% is taken from physical activity and 4.1% is taken from food preparation; of 120 min commuting, 20.3% is taken from physical activity and 5.6% is taken from food preparation. The results indicate that longer commutes are associated with behavioral patterns which over time may contribute to obesity and other poor health outcomes. These findings will assist both urban planners and researchers wishing to understand time constraints' impacts on health.

    The involvement of different oscillating neuronal systems during verbal creative thinking was investigated by multi-channel EEG measuring. The remote associates task (RAT) as a model of creative thinking in comparison to the resting condition and the simple associates task (SAT) was used. The EEG coherence along with spectral power density estimates were evaluated in each of the six frequency bands in 4-30 Hz range. We have found out RAT-related EEG changes mainly in the theta1, alpha1, alpha2 and beta2 bands. The RAT-induced cortical activation was differed from the SAT-induced EEG pattern by (i) widespread enhancement of power and coherence in the beta2, (ii) the theta1 power increase in the frontal cortex, and (iii) increased desynchronization of the alpha1,alpha2 mainly over posterior cortex together with the alpha1 coherence decrease in the prefrontal sites. Originality scores of the verbal associates positively correlated with an increase of coherence focused in the fronto-parietal regions of both hemispheres in the beta2 and in the left parieto-temporal loci in the alpha1. Additionally, more original responses positively correlated with amplitude of the alpha1 mostly in the left hemisphere. We propose that widespread cortical integration of multi-component internal processing has been simultaneously mediated during creative verbal thinking. The selectively distributed theta, alpha, and beta oscillations reflect intra- and inter-hemispheric communication networks with different functional relations to the RAT solving. The theta1 and alpha1 rhythms seem to specifically relate to top-down information processing such as deliberate sustained attention and working-memory-retention during defocused attention, respectively, whereas larger interregional synchrony in the beta2 band may mediate 'differential' attention to diffusely activating alternative meanings of words and remote associates from coarse semantic coding.

    To identify factors influencing research activity of Andalusian nurses and to find improvement strategies. Qualitative research using SWOT analysis (weaknesses, threats, strengths, opportunities). Nurses were selected deliberately in eight groups according to predetermined criteria. Analysis included categorization and relationship of factors and strategies. 81 participants were included in groups of 7-12 range. 45 categories were identified with 212 factors: 12 weaknesses (50 factors), 10 strengths (44 factors), 12 threats (68 factors) and 11 opportunities (50 factors). In addition, 32 categories were identified with 53 strategies: 14 categories of W-T strategies (42 strategies), 3 categories of S-T strategies (11 strategies), 5 categories of W-O strategies (13 strategies) and 10 categories of S-O strategies (41 strategies). Nurses identified numerous factors, mainly threats. The strategies are focused on W-T but they also suggest many but weak 5-0 strategies due to the low potential of the opportunities and strengths perceived.

    Background To date there is no established consensus of assessment criteria for evaluating research ethics review. Methods We conducted a scoping review of empirical research assessing ethics review processes in order to identify common elements assessed, research foci, and research gaps to aid in the development of assessment criteria. Electronic searches of Ovid Medline, PsychInfo, and the Cochrane DSR, ACP Journal Club, DARE, CCTR, CMR, HTA, and NHSEED, were conducted. After de-duplication, 4234 titles and abstracts were reviewed. Altogether 4036 articles were excluded following screening of titles, abstracts and full text. A total of 198 articles included for final data extraction. Results Few studies originated from outside North America and Europe. No study reported using an underlying theory or framework of quality/effectiveness to guide study design or analyses. We did not identify any studies that had involved a controlled trial - randomised or otherwise – of ethics review procedures or processes. Studies varied substantially with respect to outcomes assessed, although tended to focus on structure and timeliness of ethics review. Discussion Our findings indicate a lack of consensus on appropriate assessment criteria, exemplified by the varied study outcomes identified, but also a fragmented body of research. To date research has been largely quantitative, with little attention given to stakeholder experiences, and is largely cross sectional. A lack of longitudinal research to date precludes analyses of change or assessment of quality improvement in ethics review. PMID:26225553

    Physical Activity in the workplace has received special attention from researchers who are looking to promote lifelong health and well-being. The workplace is being investigated as a possible place to assess and create strategies to help people to become healthier. The transtheoretical model and stages of change has been adapted as a tool to assess the stages of behavioral change towards exercising. To assess the change in health behavior following a three-month exercise program based in the workplace. A quasi-experimental study design was used in which 165 employees participated in the study. An intervention program of workplace exercise was applied for three months. Participants were assessed through the transtheoretical model and stages of change questionnaire before and after intervention to understand changes in their position on the behavioral change continuum. The number of employees who were physically active increased after the workplace exercise intervention (13.9% , 95% CI 9.5 to 20.1; P = 0.009). There was a significant decrease in the proportion of employees in the pre-contemplation stage (-6.1% , 95% CI 3.3 to 10.8; P = 0.045) and contemplation stage (-11.5% , 95% CI 7.5 to 17.3; P = 0.017), and a significant increase in the action stage (10.9% , 95% CI 7.0 to 16.6; P = 0.003). Engaging in workplace exercise has a significant positive effect on health behavior and willingness to become more physically active.

    The facilities for neutron activation analysis in the HANARO (Hi-flux Advanced Neutron Application Research Reactor) are described and the main applications of NAA (Neutron Activation Analysis) are reviewed. The sample irradiation tube, automatic and manual pneumatic transfer system were installed at three irradiation holes of HANARO at the end of 1995. The performance of the NAA facility was examined to identify the characteristics of the tube transfer system, irradiation sites and custom-made polyethylene irradiation capsule. The available thermal neutron fluxes at irradiation sites are in the range of 3 x 10{sup 13} - 1 x 10{sup 14} n/cm{sup 2}{center_dot}s and cadmium ratios are in 15 - 250. For an automatic sample changer for gamma-ray counting, a domestic product was designed and manufactured. An integrated computer program (Labview) to analyse the content was developed. In 2001, PGNAA (Prompt Gamma Neutron Activation Analysis) facility has been installed using a diffracted neutron beam of ST1. NAA has been applied in the trace component analysis of nuclear, geological, biological, environmental and high purity materials, and various polymers for research and development. The improvement of analytical procedures and establishment of an analytical quality control and assurance system were studied. Applied research and development for the environment, industry and human health by NAA and its standardization were carried out. For the application of the KOLAS (Korea Laboratory Accreditation Scheme), evaluation of measurement uncertainty and proficiency testing of reference materials were performed. Also to verify the reliability and to validate analytical results, intercomparison studies between laboratories were carried out. (author)

    Full Text Available This paper provides a brief overview of the progress made towards active fault research in India. An 8 m high scarp running for more than 80 km in the Rann of Kachchh is the classical example of the surface deformation caused by the great earthquake (1819 Kachchh earthquake. Integration of geological/geomorphic and seismological data has led to the identification of 67 active faults of regional scale, 15 in the Himalaya, 17 in the adjoining foredeep with as many as 30 neotectonic faults in the stable Peninsular India. Large-scale trenching programmes coupled with radiometric dates have begun to constraint the recurrence period of earthquakes; of the order of 500–1000 years for great earthquakes in the Himalaya and 10,000 years for earthquakes of >M6 in the Peninsular India. The global positioning system (GPS data in the stand alone manner have provided the fault parameters and length of rupture for the 2004 Andaman Sumatra earthquakes. Ground penetration radar (GPR and interferometric synthetic aperture radar (InSAR techniques have enabled detection of large numbers of new active faults and their geometries. Utilization of modern technologies form the central feature of the major programme launched by the Ministry of Earth Sciences, Government of India to prepare geographic information system (GIS based active fault maps for the country.

    Recovery from concussion generally follows a trajectory of gradual improvement, but symptoms can abruptly worsen with exertion. This phenomenon is poorly understood. To characterize the incidence, course, and clinical significance of symptom exacerbations (spikes) in children after concussion. This secondary analysis of clinical trial data analyzes 63 eligible participants prospectively recruited from an emergency department who were asked to complete a postconcussion symptom scale and record their activities in a structured diary for the next 10 days. They completed standardized assessments of symptoms (postconcussion symptom scale), cognition (Immediate Post-Concussion Assessment and Cognitive Testing), and balance (Balance Error Scoring System) 10 days following the injury. Eligible participants were aged 11 to 18 years and sustained a concussion (according to the Centers for Disease Control and Prevention criteria) that did not result in an abnormal computed tomography scan or require hospital admission. The trial was conducted from May 2010 to December 2012, and the analysis was conducted from November 2015 to February 2016. The occurrence of symptom spikes, defined as an increase of 10 or more points on the postconcussion symptom scale over consecutive days. Of the 63 participants, there were 41 boys (65.1%) and 22 girls (34.9%), and the mean (SD) age was 13.8 (1.8) years. Symptom spikes occurred in one-third of the sample (20 participants [31.7%]). Symptom spikes tended to partially resolve within 24 hours. An abrupt increase in mental activity (ie, returning to school and extracurricular activities) from one day to the next increased the risk of a symptom spike (relative risk, 0.81; 95% CI, 0.21-3.21), but most symptom spikes were not preceded by a documented increase in physical or mental activity. Patients with symptom spikes were initially more symptomatic in the emergency department and throughout the observation period but did not differ from the group

    The pathogenesis of chronic urticaria is incompletely understood. There is growing interest in the role of the coagulation cascade in chronic urticaria. We aimed to assess the possible activation of the coagulation cascade in chronic spontaneous urticaria (CSU) in relation to disease severity and activity. This study was conducted on 30 patients with active CSU and 30 apparently healthy individuals as controls. Patients with acute urticaria, physical urticaria, or any form of urticaria other than spontaneous urticaria were excluded. Plasma levels of D-dimer and activated factor VII (FVIIa) were measured by ELISA at baseline for all recruited patients and controls. In addition, they were measured for CSU patients after complete disease remission. Plasma levels of D-dimer and FVIIa were significantly higher among patients with active CSU than among healthy controls. D-dimer levels were lowest among patients with grade 1 severity and highest among those with grade 4 severity. Factor VIIa levels did not differ significantly according to disease severity grades. After complete disease remission, there was a significant dramatic drop in levels of D-dimer and FVIIa among patients. We conclude that activation of the coagulation cascade occurs in CSU, and we demonstrate the novel finding that activated factor VII levels are significantly reduced after medical therapy, confirming the implication of the extrinsic pathway activation in CSU. Future controlled studies may investigate the role of anticoagulant therapy in refractory chronic urticaria. Copyright © 2014 SEICAP. Published by Elsevier Espana. All rights reserved.

    Full Text Available Abstract Background While moderate and vigorous leisure time physical activities are well documented to decrease the risk for cardiovascular disease, several studies have demonstrated an increased risk for cardiovascular disease in workers with high occupational activity. Research on the underlying causes to the contrasting effects of occupational and leisure time physical activity on cardiovascular health is lacking. The aim of this study was to examine the relation of objective and self-report measures of occupational and leisure time physical activity with 24-h ambulatory systolic blood pressure (BP. Methods Results for self-reported physical activity are based on observations in 182 workers (60% male, mean age 51 years, while valid objective physical activity data were available in 151 participants. The usual level of physical activity was assessed by 5 items from the Job Content Questionnaire (high physical effort, lifting heavy loads, rapid physical activity, awkward body positions and awkward positions of head or arms at work and one item asking about the general level of physical activity during non-working time. On a regular working day, participants wore an ambulatory BP monitor and an accelerometer physical activity monitor during 24 h. Associations were examined by means of Analysis of Covariance. Results Workers with an overall high level of self-reported occupational physical activity as well as those who reported to often lift heavy loads at work had a higher mean systolic BP at work, at home and during sleep. However, no associations were observed between objectively measured occupational physical activity and BP. In contrast, those with objectively measured high proportion of moderate and vigorous leisure time physical activity had a significantly lower mean systolic BP during daytime, while no differences were observed according to self-reported level of leisure time physical activity. Conclusions These findings suggest that

    The development of research-based active-learning instructional methods in physics has significantly altered the landscape of U.S. physics education during the past 20 years. Based on a recent review [D.E. Meltzer and R.K. Thornton, Am. J. Phys. 80, 478 (2012)], we define these methods as those (1) explicitly based on research in the learning and teaching of physics, (2) that incorporate classroom and/or laboratory activities that require students to express their thinking through speaking, writing, or other actions that go beyond listening and the copying of notes, or execution of prescribed procedures, and (3) that have been tested repeatedly in actual classroom settings and have yielded objective evidence of improved student learning. We describe some key features common to methods in current use. These features focus on (a) recognizing and addressing students' physics ideas, and (b) guiding students to solve problems in realistic physical settings, in novel and diverse contexts, and to justify or explain the reasoning they have used.

    Neglected tropical diseases (NTDs) are an extremely important issue facing global health care. To improve "access to health" where people are unable to access adequate medical care due to poverty and weak healthcare systems, we have established two consortiums: the NTD drug discovery research consortium, and the pediatric praziquantel consortium. The NTD drug discovery research consortium, which involves six institutions from industry, government, and academia, as well as an international non-profit organization, is committed to developing anti-protozoan active compounds for three NTDs (Leishmaniasis, Chagas disease, and African sleeping sickness). Each participating institute will contribute their efforts to accomplish the following: selection of drug targets based on information technology, and drug discovery by three different approaches (in silico drug discovery, "fragment evolution" which is a unique drug designing method of Astellas Pharma, and phenotypic screening with Astellas' compound library). The consortium has established a brand new database (Integrated Neglected Tropical Disease Database; iNTRODB), and has selected target proteins for the in silico and fragment evolution drug discovery approaches. Thus far, we have identified a number of promising compounds that inhibit the target protein, and we are currently trying to improve the anti-protozoan activity of these compounds. The pediatric praziquantel consortium was founded in July 2012 to develop and register a new praziquantel pediatric formulation for the treatment of schistosomiasis. Astellas Pharma has been a core member in this consortium since its establishment, and has provided expertise and technology in the area of pediatric formulation development and clinical development.

    2009-10-15

    Aim: To determine whether there is evidence of a reduction in radiology research activity in the UK following the implementation of the European research ethics legislation, which came in to force in 2001 and has been widely criticised as an impediment to research. Materials and methods: A bibliometric analysis was performed by searching PubMed for all first-author publications from UK departments of 'radiology' or 'medical imaging' between 1995 and 2007. Results were subcategorized into those papers published in the highest cited general radiology journals and by publication type: original research, reviews, and case reports. Results: From 1995 to 2007 the total number of publications rose by 6.5% from 137 to 146 with the increase occurring in non-general radiology journals. Original articles fell from 18 in 1995 to 12 in 2003, but then rose to 24 by 2007 (33% rise). This dip was paralleled by a fall and then recovery in case report publications. The most dramatic change has been in the number of review articles, which has increased more than eightfold from seven in 1995 to 65 in 2007 to become the most common form of publication. Conclusion: The overall number of original scientific articles, published by first-author UK radiologists, has increased slightly over the last 12 years despite a temporary fall associated with the introduction of new research ethics legislation.

    The purpose of this study was to investigate the level of research activity, research use, research interests and research skills in the social care workforce in two UK councils with social service responsibilities (CSSRs). A cross-sectional survey was conducted of the social care workforce in two CSSRs (n = 1512) in 2005. The sample was identified in partnership with the councils, and included employees with professional qualifications (social workers and occupational therapists); staff who have a role to assess, plan and monitor care; service managers; commissioners of services; and those involved with social care policy, information management and training. The survey achieved a response rate of 24% (n = 368). The Internet was reported as an effective source of research information; conversely, research-based guidelines were reported to have a low impact on practice. Significant differences were found in research use, by work location, and postgraduate training. Most respondents saw research as useful for practice (69%), and wanted to collaborate in research (68%), but only 11% were planning to do research within the next 12 months. Having a master's degree was associated with a greater desire to lead or collaborate in research. A range of research training needs, and the preferred modes of delivery were identified. Support to increase research activity includes protected time and mentorship. The study concludes that a range of mechanisms to make research available for the social care workforce needs to be in place to support evidence-informed practice. Continual professional development to a postgraduate level supports the use and production of evidence in the social care workforce, and promotes the development of a research culture. The term research is used to include service user consultations, needs assessment and service evaluation. The findings highlight a relatively large body of the social care workforce willing to collaborate and conduct research

    While the perception of stickiness serves as one of the fundamental dimensions for tactile sensation, little has been elucidated about the stickiness sensation and its neural correlates. The present study investigated how the human brain responds to perceived tactile sticky stimuli using functional magnetic resonance imaging (fMRI). To evoke tactile perception of stickiness with multiple intensities, we generated silicone stimuli with varying catalyst ratios. Also, an acrylic sham stimulus was prepared to present a condition with no sticky sensation. From the two psychophysics experiments-the methods of constant stimuli and the magnitude estimation-we could classify the silicone stimuli into two groups according to whether a sticky perception was evoked: the Supra-threshold group that evoked sticky perception and the Infra-threshold group that did not. In the Supra-threshold vs. Sham contrast analysis of the fMRI data using the general linear model (GLM), the contralateral primary somatosensory area (S1) and ipsilateral dorsolateral prefrontal cortex (DLPFC) showed significant activations in subjects, whereas no significant result was found in the Infra-threshold vs. Sham contrast. This result indicates that the perception of stickiness not only activates the somatosensory cortex, but also possibly induces higher cognitive processes. Also, the Supra- vs. Infra-threshold contrast analysis revealed significant activations in several subcortical regions, including the pallidum, putamen, caudate and thalamus, as well as in another region spanning the insula and temporal cortices. These brain regions, previously known to be related to tactile discrimination, may subserve the discrimination of different intensities of tactile stickiness. The present study unveils the human neural correlates of the tactile perception of stickiness and may contribute to broadening the understanding of neural mechanisms associated with tactile perception.

    A wide variety of probiotic products has been introduced into the market in the past decade. Research trends and activity on probiotics help understand how these products were evolved and their potential future role in medicine. The objective of this study was to assess the research activity on probiotics in pediatrics using bibliometric indicators and network visualization. Original and review articles on probiotics in pediatrics published worldwide were retrieved from SciVerse, Scopus (1994-2014) and analyzed. VOSviewer was used for network visualization. The total number of documents published on probiotics in pediatrics was 2817. Research activity on probiotics in pediatrics showed approximately 90- fold increase during the study period. Approximately 22 % of published articles originated from USA and has the greatest share, however, Finland ranked first when data were stratified by population or income. The most productive institution in this field was Turku University in Finland with 82 (2.91 %) articles. Half of the prolific authors were also from Finland. Most of the published research activity appeared in Journal of Pediatric Gastroenterology and Nutrition. Most frequently encountered title terms include nutrition, infant formula, necrotizing enetrocolitis, allergy, and diarrhea. The total number of citations for the retreived documents documents was 70991, and the average citation per article was 25.20. Interest in probiotic research and its potential benefits in pediatric ailments is relatively recent but significantly increasing. Bibliometric analysis can be used as an indicator of the importance and growth of probiotic use in pediatrics.

    The time series of the length of day (LOD) and the observational Pacific sea level during l962.0-1990.0 are used to study the relation between Earth rotation and equatorial oceanic activities.The results show that (i) the sea level is apparently rising at an average rate of about 1.75±.01mm/a during the past 30 years,(ii) there are large-scale eastward and westward water motions in the upper equatorial Pacific zone,which,according to the dynamical analysis of the angular momentum of the large-scale sea water motion in Pacific Ocean related to the Earth rotation axis accounts for about 30% of the change in ititerannual Eatlh rotation rate; (iii) the interannual changes in Earth rotation also cause changes in the distribution of the water mass in equatorial Pacific,and affect the formation of ENSO events.Based on these results,we give a new model for the interaction between equatorial ocean and Earth rotation.

  13. On the neglect of causality principles in solar activity - climate relations.

    Stauning, Peter

    2010-05-01

    Many research papers have claimed to demonstrate close relations between solar activity and the terrestrial climate. In most cases the relations have been based on comparisons between time series of solar activity parameters, for instance sunspot numbers, and climate parameters, for instance terrestrial temperatures. However, many of the reported close relations are based on skilfully manipulated data and neglect of basic causality principles. For cause-effect relations to be reliably established, the cause must obviously happen prior to the effects. Thus it is problematic to use, for instance, running averages of parameters if the result depends too much on posterior elements of the causative time series or precursory elements of the effects. Even more neglected are the causality principles for cause-effect relations with a strongly varying source function. Damping of source variations by smoothing data handling introduces additional implied delays, which should be considered in the judgement of apparent correlations between processed time series of cause and effect parameters. The presentation will discuss examples of frequently quoted solar activity-climate relations (e.g., by Reid, Friis-Christensen, and Svensmark), which violate basic causality principles.

  14. A classification and summarization method for analysis of research activities in an academic faculty

    Eduardo Rocha Loures

    Full Text Available Abstract Nowadays, more and more scientific research activities are carried out in different laboratories and universities, which not only play an important role in the development of science and technology, but also show a significant inference on education. The improvement of the research capability of an academic faculty can directly impact the quality of education, bring innovations to Industrial Engineering curriculum proposals, and guarantee the subjects are up to date. The investigation of the existing issues in the current research activities is usually considered as the primary and challenging step. As the output of research activities, academic articles are often considered as a kind of evidence-based resources for the investigation. Despite some methodological efforts have been made by existing article review methods, less attention has been paid to discover the implicit academic relationships among the academic staffs and to investigate their research expertise. The objective of this study is to address this existing drawback through the proposition of an Academic Information Classification and Summarization method. A case study is carried out in the Industrial and System Engineering Graduate Program (PPGEPS, PUCPR, Brazil. The result not only highlights the advantages that can be obtained from this proposition from the education perspective related to Industrial Engineering, but also can be used as evidence to balance and compare an academic staff’s research expertise and his/her teaching disciplines.

    Actively involving people with intellectual disabilities (ID) in health research, also known as inclusive health research, is increasingly popular. Currently, insight into experiences of this type of research is scarce. To gain insight into this topic, a structured literature review was conducted focussing on (1) existing theories, (2) inclusive methods, (3) added value and (4) barriers and facilitators. Literature published between January 2000 and January 2014 was included covering keywords related to ID and inclusive health research. Searches were performed in Pubmed, CINAHL, PsycINFO, EMBASE and MEDLINE databases, resulting in 26 included papers. Papers were quality assessed and analysed using qualitative data analysis software. Four theories were often simultaneously addressed: participatory research, emancipatory research, inclusive research and Arnstein's ladder. Barriers and facilitators could be divided into preparing, undertaking and finalising phases of research. Authors indicated that their motivation to conduct inclusive health research was based on demands by policy and funding bodies or was based on ethical considerations (i.e., ethical notions and giving people with ID a voice). Upon completion, authors perceived increased quality and validity of their research and several benefits for stakeholders (i.e., people with ID, researchers and healthcare professionals). Overall, there was consistency in their perception of the most important aspects of inclusive health research. Based on the analysis of included papers, four recommendations of inclusive health research with people with ID were found. Inclusive health research should be: (1) tailoring to the specific study; (2) anticipating all stakeholders; (3) considering its added value; and (4) providing insight into its process.

    To systematically review the literature regarding rest and return to activity after sport-related concussion. The search was conducted in the Cochrane Central Register of Controlled Trials, CINAHL, SPORTDiscus, Educational Resources Information Center, Ovid MEDLINE, and PubMed using terms related to concussion, mild traumatic brain injury, physical and cognitive rest, and return to activity. Studies were included if they were published in English; were original research; and evaluated the use of, compliance with, or effectiveness of physical or cognitive rest or provided empirical evidence supporting the graded return-to-activity progression. The study design, patient or participant sample, interventions used, outcome measures, main results, and conclusions were extracted, as appropriate, from each article. Articles were categorized into groups based on their ability to address one of the primary clinical questions of interest: use of rest, rest effectiveness, compliance with recommendations, or outcome after graded return-to-activity progression. A qualitative synthesis of the results was provided, along with summary tables. Our main findings suggest that rest is underused by health care providers, recommendations for rest are broad and not specific to individual patients, an initial period of moderate physical and cognitive rest (eg, limited physical activity and light mental activity) may improve outcomes during the acute postinjury phase, significant variability in the use of assessment tools and compliance with recommended return-to-activity guidelines exists, and additional research is needed to empirically evaluate the effectiveness of graded return-to-activity progressions. Furthermore, there is a significant need to translate knowledge of best practices in concussion management to primary care providers.

    Operational space weather forecast is for contribution to social infrastructure than for academic interests. These user need will determine the target of research, e.g., the precision level, spatial and temporal resolution and/or required lead time. We, NICT, aim two target in the present mid-term strategic plan, which are (1) forecast of ionospheric disturbance influencing to satellite positioning, and (2) forecast of disturbance in radiation belt influencing to satellite operation. We have our own observation network and develop empirical and numerical models for achieving each target. However in actual situation, it is much difficult to know the user needs quantitatively. Most of space weather phenomena makes the performance of social infrastructure poor, for example disconnect of HF communication, increase of GNSS error. Most of organizations related to these operation are negative to open these information. We have personal interviews to solve this issue. In this interview, we try to collect incident information related to space weather in each field, and to retrieve which space weather information is necessary for users. In this presentation we will introduce our research and corresponding new service, in addition to our recent scientific results.

    Full Text Available Background The aim of the research was to present sexual functioning of pregnant women in terms of their assessment of the sexual life and marital relation. The study included 61 pregnant women (31 with high-risk pregnancy and 30 with a normal course of pregnancy, aged on average 28.5 years and pregnant on average for 27.5 weeks. Participants and procedure The study was based on the sociodemographic questionnaire The Female Sexual Function Questionnaire, SFQ28 (designed by Quirk et al., 2005, the Sexual Quality of Life Questionnaire – Female Version, SQoL-F (designed by Symonds et al., 2005, and the Dyadic Adjustment Scale, DAS (designed by Cieślak, 1989. Results The obtained results reveal changes in sexual functioning during pregnancy, mostly in terms of desire and excitement. The groups differed significantly in terms of sexual activity. Women with pathological pregnancy obtained lower results on the scales of desire, arousal, orgasm and satisfaction with sexual relationship. With every subsequent pregnancy week, both groups obtained lower results on the scales of arousal, orgasm and satisfaction with sexual activity. Neither pregnancy nor its length was related to the assessment of satisfaction with marital relation. Conclusions The conducted data analysis indicates that the subjective assessment of sexual life is related to the assessment of marital relation on the scale of emotional expression and relation coherence. No relation of sexual activity and sexual life with the assessment of the quality of marital relation was proved. However, the assessment of sexual life is related significantly to the assessment of the quality of marital relation.

    Sleep-related memory consolidation has received increasing attention in recent years. Because previous research has focused on healthy young adults, only very few studies have been conducted in patients with psychiatric disorders so far. The investigation of sleep-related memory consolidation in depression offers a wide range of future research opportunities and can therefore be regarded as an emerging field of research. This article gives a short overview of current knowledge of sleep-related memory consolidation in healthy young adults and builds a bridge to psychiatry and depression, where further research is urgently needed.

    Full Text Available Performance evaluation of scientific work on regional and individual levels can be achieved by the using scientometric methods of a quantitative analysis of bibliographic information available in such databases as Science Citation Index (SCI. Unfortunately, Kazakhstan scientific journals have not been included yet in the Thomson Reuters Corp. register of periodicals, that substantially distorts the actual national scientometric indexes. The analysis of Database “National Citation Reports” (Kazakhstan, which correlated with a contribution of Kazakhstan into the world science development, has shown the low level of research activities of Kazakhstan scientists on international arena. So, the share of international publications of Kazakhstan in the global flow is equal to 0,021 % (1044 doc. that corresponds to the 87th place in the general list of countries of 177 names. Subject to the ranking of countries into groups by the number of the published works, Kazakhstan is referring to the group of 46 countries having 1000-10000 publications over 5 years, of which 8,6% in  medicine. In this article the use of statistics and appropriate software by the authors of original articles in such journals as recommended by the Kazakh National Centre for Scientific & Technical Expertise (NCSTE and included in the Database еlibrary.kz was evaluated. Research was conducted according to Research Report, due to which a research design and statistical analysis methods were estimated.  In the rating of the research design, the authors of articles mostly used as follows: description of a series of cases–63,2%, description of the individual cases -27,1%, and description of specific cases–9,1%. A scope of selection in Section “Research Methods” was only calculated in 21,8% of cases, and in 63,9% of cases there was no description how the selection was carried out. Methods of analytical statistics were used in the 46,0% of cases. And there were references to

The ISDA makes use of the well-proven archive standards of the Planetary Data System (PDS) and planning to follow IPDA guidelines. This is to comply with the global standards for long term preservation of the data to maintain the usability and facilitate scientific community with the high quality data for their analysis. The data deliveries from various instruments are already started to ISSDC. The science archives received from MiniSAR and M3 are peer reviewed by the host organizations and hence no further reviews planned at ISSDC. For the other instrument data archives, peer reviews are planned at ISSDC, for which the activity will start during April 2010. A pre review has already been carried out for certain instrument data sets and currently the review comments are being incorporated. The data for the first normal phase operation (November 2008 to February 2009) is planned to be made available (through long term archive) sometime during August 2010 to the users. However the data is already available to the PI teams in the PDS standard, for analysis and use in the instrument cross calibration. Chandrayaan-2 is the next planetary mission to Moon from ISRO in future (which will carry rovers; expected to give a good amount of science data, which is also planned to be archived in ISSDC for dissemination.

    2014-07-01

    Chemometrics is a new branch of chemistry which is widely applied to various fields of analytical chemistry. Chemometrics can use theories and methods of mathematics, statistics, computer science and other related disciplines to optimize the chemical measurement process and maximize access to acquire chemical information and other information on material systems by analyzing chemical measurement data. In recent years, traditional Chinese medicine has attracted widespread attention. In the research of traditional Chinese medicine, it has been a key problem that how to interpret the relationship between various chemical components and its efficacy, which seriously restricts the modernization of Chinese medicine. As chemometrics brings the multivariate analysis methods into the chemical research, it has been applied as an effective research tool in the composition-activity relationship research of Chinese medicine. This article reviews the applications of chemometrics methods in the composition-activity relationship research in recent years. The applications of multivariate statistical analysis methods (such as regression analysis, correlation analysis, principal component analysis, etc. ) and artificial neural network (such as back propagation artificial neural network, radical basis function neural network, support vector machine, etc. ) are summarized, including the brief fundamental principles, the research contents and the advantages and disadvantages. Finally, the existing main problems and prospects of its future researches are proposed.

    2013-10-01

    The purpose of this project is to conduct a comprehensive and systematic scoping review to identify and document the breadth of literature related to physical activity-related injuries in older adults. The population of interest was adults (both males and females) over the age of 65 years, participating in exercise, leisure-time, or sport-type physical activities. The initial search yielded 16,828 articles, with 43 articles ultimately included. The final 43 articles utilized the following study designs: three experimental (two randomized control and one non-randomized control), 14 prospective studies, and 26 retrospective. The results of this scoping review would suggest that it may be premature to provide definitive incidence rates, causes, and correlates of physical activity-related injuries in older adults. However, the current literature does not suggest that older adults are at an increased risk of injury from participation in physical activities. Future research should utilize a consistent definition of 'injury' and consistent and comprehensive descriptors of injuries--including intensity level of engagement of activity and burden/severity of injury. In addition, injury rates in specific populations are needed, particularly for the oldest-old, for those in assisted-living situations, and for subgroups with clinical conditions. Finally, greater surveillance and documentation of older adult initiatives and interventions are needed in order to identify programs successful in reducing the injury rates of their target populations.

    Since many years research programs have been set up to study the relationship between asbestos occupational exposure and development of asbestos-related lung diseases in electricity production plants workers. In the year 2000 a new study of asbestos-related lung abnormalities prevalence in italian geothermal and idrothermal power plant maintenance workers was planned. The cohort comprised 3891 subjects. To meet the criteria, only workers in service for at least six months before 1990 and still in service at power plants in May 2000 were included in the study; chest X-rays were taken and made anonymous. Independent reading of X-rays was made by two groups of specialists, and a third reading of selected discordant readings X-rays was made by another group of specialists. A further diagnostic protocol (including HRCT) was planned when two out of three readings showed the presence of asbestos related lung abnormalities. The analysis was made on 3063 subjects (78.7% of the cohort). The number of asbestos-related abnormalities in two out of three X-ray readings was 122 (4%). The further diagnostic protocol, that included occupational and pathological anamnesis and HRCT, confirmed an asbestos-related occupational lung abnormalities in 41 cases (1.3% out of 3063 subjects). The prevalence of asbestos-related lung abnormalities among 3063 power plant maintenance workers was 1.3%. If all the cases of lung abnormalities so far detected (data are still provisional) had developed only in the power plant environment, and not in previous working activities, the prevalence of lung abnormalities would be extremely low. These data support the evidence of limited exposure levels to asbestos in this working environment And bears witness to the success of preventive measures to control this specific risk.

    The objective of this study was to analyze quantity, assess quality, and investigate international collaboration in research from Arab countries in the field of public, environmental and occupational health. Original scientific articles and reviews published from the 22 Arab countries in the category "public, environmental & occupational health" during the study period (1900 - 2012) were screened using the ISI Web of Science database. The total number of original and review research articles published in the category of "public, environmental & occupational health" from Arab countries was 4673. Main area of research was tropical medicine (1862; 39.85%). Egypt with 1200 documents (25.86%) ranked first in quantity and ranked first in quality of publications (h-index = 51). The study identified 2036 (43.57%) documents with international collaboration. Arab countries actively collaborated with authors in Western Europe (22.91%) and North America (21.04%). Most of the documents (79.9%) were published in public health related journals while 21% of the documents were published in journals pertaining to prevention medicine, environmental, occupational health and epidemiology. Research in public, environmental and occupational health in Arab countries is in the rise. Public health research was dominant while environmental and occupation health research was relatively low. International collaboration was a good tool for increasing research quantity and quality.

  16. Pressure-related activation of inducible nitric oxide synthase

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    A lot of reports suggested that inducible nitric oxide synthase (iNOS) has a very different nature from constitutive NOS including endothelial NOS (eNOS) and neural NOS (nNOS). When exposed to cytokines or bacterial products, iNOS could be greatly activated and produces hundreds or thousands fold more NO than it does usually. Whether iNOS activation is arterial pressure related is not clear. In the present experiment, we studied three groups(n=6) of Sprague Dawley (SD) rats with implanted aorta and venous catheters that were maintained on 1 mEq/d, 12.5 mEq/d and 25 mEq/d of sodium intake respectively. Pulsatile arterial pressure signals from the amplifier were sent to a digital computer and the urine samples were taken every other day for nitrate/nitrite excretion (UNOx) assay using Greiss Reaction. After 6 days infusion, the rats were euthanized with an overdose of sodium pentobarbital, and the renal medullas were rapidly removed and frozen on dry ice for iNOS activity assay. Morever separate groups of hypertensive rats including spontaneously hypertensive rat (SHR, n=6) and High NaCl-induced hypertensive rat (NaHR, n=6) were used to measure renal iNOS protein by Western Blotting. The results showed that the mean arterial pressure (MAP) were significantly increased with the increase intake of sodium, the MAP (mmHg) at day 6 were 99.6±3.5,116.65±4.2 and 125.43±4.5, and the iNOS activity (nmol*g-1 protein*min-1) were 122.3±23.4, 342.4±35.6 and 623.9±65.4 in 1 mEq/d, 12.5 mEq/d and 25 mEq/d of sodium intake-rats respectively. At the same time, UNOx at day 6 were also increased, in turn, to 5 865.6±343.0 (for 12.5 mEq/d intake-rats) and (9 642.8±1 045.3) (for 25 mEq/d sodium intake-rats) nmol/d from (3 834.9±234.8) nmol/d of 1 mEq/d sodium intake-rats respectively. Western blotting showed that the renal medullary iNOS protein in SHR and NaHR were increased by 178%±13% and 104%±9% of normal Wistar rats. The data indicates that elevated arterial pressure

    Information technology can help individuals to change their health behaviors. This is due to its potential for dynamic and unbiased information processing enabling users to monitor their own progress and be informed about risks and opportunities specific to evolving contexts and motivations. However, in many behavior change interventions, information technology is underused by treating it as a passive medium focused on efficient transmission of information and a positive user experience. To conduct an interdisciplinary literature review to determine the extent to which the active technological capabilities of dynamic and adaptive information processing are being applied in behavior change interventions and to identify their role in these interventions. We defined key categories of active technology such as semantic information processing, pattern recognition, and adaptation. We conducted the literature search using keywords derived from the categories and included studies that indicated a significant role for an active technology in health-related behavior change. In the data extraction, we looked specifically for the following technology roles: (1) dynamic adaptive tailoring of messages depending on context, (2) interactive education, (3) support for client self-monitoring of behavior change progress, and (4) novel ways in which interventions are grounded in behavior change theories using active technology. The search returned 228 potentially relevant articles, of which 41 satisfied the inclusion criteria. We found that significant research was focused on dialog systems, embodied conversational agents, and activity recognition. The most covered health topic was physical activity. The majority of the studies were early-stage research. Only 6 were randomized controlled trials, of which 4 were positive for behavior change and 5 were positive for acceptability. Empathy and relational behavior were significant research themes in dialog systems for behavior change, with

    Cryptococcosis is one of the most important invasive fungal infections and is a significant contributor to the mortality associated with HIV/AIDS. As part of our program to repurpose molecules related to the selective estrogen receptor modulator (SERM) tamoxifen as anti-cryptococcal agents, we have explored the structure-activity relationships of a set of structurally diverse SERMs and tamoxifen derivatives. Our data provide the first insights into the structural requirements for the antifungal activity of this scaffold. Three key molecular characteristics affecting anti-cryptococcal activity emerged from our studies: 1) the presence of an alkylamino group tethered to one of the aromatic rings of the triphenylethylene core; 2) an appropriately sized aliphatic substituent at the 2 position of the ethylene moiety; and 3) electronegative substituents on the aromatic rings modestly improved activity. Using a cell-based assay of calmodulin antagonism, we found that the anti-cryptococcal activity of the scaffold correlates with calmodulin inhibition. Finally, we developed a homology model of C. neoformans calmodulin and used it to rationalize the structural basis for the activity of these molecules. Taken together, these data and models provide a basis for the further optimization of this promising anti-cryptococcal scaffold.

    This paper discusses research/industry interaction in application-oriented research groups specializing in the development of optoelectronic instruments and measurement methods. The research groups are working in Oulu, a city in Northern Finland, in an industrial environment consisting originally of pulp and paper industries together with metalworking and engineering industries. These established industrial areas are active in adopting new technologies for automation and process renewal. Furthermore, new emerging businesses are being generated through pilot installations and new product ideas created by research groups. The technologies considered are optical and infrared process analyzers, semiconductor laser-based dimension measurements and optoelectronic hybrid module fabrication. Examples of new products and enterprises employing these technologies are given. Additional skills and education especially in miniature optics and related constructions, are considered important for the future.

    During fiscal 1984, major programmatic activities in AFRD continued in each of five areas: accelerator operations, highlighted by the work of nuclear science users, who produced clear evidence for the formation of compressed nuclear matter during heavy-ion collisions; high-energy physics, increasingly dominated by our participation in the design of the Superconducting Super Collider; heavy-ion fusion accelerator research, which focused on the design of a four-beam experiment as a first step toward assessing the promise of heavy-ion inertial-confinement fusion; and research at the Center for X-Ray Optics, which completed its first year of broadly based activities aimed at the exploitation of x-ray and ultraviolet radiation. At the same time, exploratory studies were under way, aimed at investigating major new programs for the division. During the past year, for example, we took a preliminary look at how we could use the Bevatron as an injector for a pair of colliding-beam rings that might provide the first glimpse of a hitherto unobserved state of matter called the quark-gluon plasma. Together with Livermore scientists, we also conducted pioneering high-gain free-electron laser (FEL) experiments and proposed a new FEL-based scheme (called the two-beam accelerator) for accelerating electrons to very high energies. And we began work on the design of the Coherent XUV Facility (CXF), an advanced electron storage ring for the production of intense coherent radiation from either undulators or free-electron lasers.

    Reducing nutrition-related health problems in Arab countries requires an understanding of the performance of Arab countries in the field of nutrition and dietetics research. Assessment of research activity from a particular country or region could be achieved through bibliometric analysis. This study was carried out to investigate research activity in "nutrition and dietetics" in Arab countries. Original and review articles published from Arab countries in "nutrition and dietetics" Web of Science category up until 2012 were retrieved and analyzed using the ISI Web of Science database. The total number of documents published in "nutrition and dietetics" category from Arab countries was 2062. This constitutes 1% of worldwide research activity in the field. Annual research productivity showed a significant increase after 2005. Approximately 60% of published documents originated from three Arab countries, particularly Egypt, Kingdom of Saudi Arabia, and Tunisia. However, Kuwait has the highest research productivity per million inhabitants. Main research areas of published documents were in "Food Science/Technology" and "Chemistry" which constituted 75% of published documents compared with 25% for worldwide documents in nutrition and dietetics. A total of 329 (15.96%) nutrition - related diabetes or obesity or cancer documents were published from Arab countries compared with 21% for worldwide published documents. Interest in nutrition and dietetics research is relatively recent in Arab countries. Focus of nutrition research is mainly toward food technology and chemistry with lesser activity toward nutrition-related health research. International cooperation in nutrition research will definitely help Arab researchers in implementing nutrition research that will lead to better national policies regarding nutrition.

  7. Research progress in nonlinear analysis of heart electric activities

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Nonlinear science research is a hot point in the world. It has deepened our cognition of determinism and randomicity, simplicity and complexity, noise and order and it will profoundly influence the progress of the study of natural science, including life science.Life is the most complex nonlinear system and heart is the core of lifecycle system. In the late more than 20 years, nonlinear research on heart electric activities has made much headway. The commonly used parameters are based on chaos and fractal theory, such as correlation dimension, Lyapunov exponent, Kolmogorov entropy and multifractal singularity spectrum. This paper summarizes the commonly used methods in the nonlinear study of heart electric signal. Then, considering the shortages of the above traditional nonlinear parameters, we mainly introduce the results on short-term heart rate variability (HRV) signal (500 R-R intervals) and HFECG signal (1-2s). Finally, we point out it is worthwhile to put emphasis on the study of the sensitive nonlinearity parameters of short-term heart electric signal and their dynamic character and clinical effectivity.

  8. The Relation between Extreme Weather Events and the Solar Activity

    Science.gov (United States)

    Battinelli, P.; di Fazio, A.; Torelli, M.

    The oscillating part of the solar irradiance drives the cyclic component of the variations of the terrestrial atmosphere's thermodynamic state. In particular, the average temperature, and thus the turbulent atmospheric fuxes, are influenced. Reliable temperature data exist from ~220,000 years, while accurate solar irradiance space measurements (not affected by the atmosphere's absorption) are available only since 1979. Actually, there is a rather long data-set regarding solar activity, indicated by the Wolf number, which is found to be well correlated with the total solar flux. Thus, we use the Wolf number as a quantitative proxy of the incident flux, even in the interval before the space-based measurements. The fraction of solar energy trapped in the atmosphere due to the re-absorption of the infrared radiation by the greenhouse gases is an increasing function of time (in the latter 150-160 years). Over this interval, we spectrally analyzed the time series of both the Wolf number and the frequencies of extreme meteorological events, isolating and removing in the latter the cyclic components due to the periodic part of the radiative forcing exherted by the Sun. We were thus able to determine the time trend in the data regarding the observed frequencies of the U.S. continental tornadoes (National Center for Atmospheric Research) and of the global cyclones (hurricanes and tropical storms on all ocean basins, National Ocean and Atmospheric Administration). We find, for both the data sets an exponential behaviour, with e-folding times: for the cyclones tau ~= 110 years, and for the tornadoes tau ~= 70 years. We are happy to have given --through this work-- a contribution to the interdisciplinary scientific process coordinated by the IPCC (Intergovernmental Panel on Climate Change) through the ICSU (International Council of Scientific Unions) which takes place a latere of the international negotiations under the United Nations Framework Convention on Climate Change.

    Objective To describe the relationship of the mother's physical activity to the birth size of her baby in a rural Indian population. Design Prospective observational study. Setting Six villages near Pune, Maharashtra, India. Subjects 797 women were studied after excluding abortions and termination of pregnancies (112), fetal anomalies (8), multiple pregnancies (3), incomplete pre-pregnancy anthropometry (14) and pregnancies detected later than 21 weeks of gestation (168). Method An activity questionnaire was developed after focus group discussions and incorporated community-specific activities. It was validated against an observer-maintained diary. Activity scores were derived using published data on energy costs to weight the contributions of various activities. It was then administered to assess physical activity at 18 (± 2) and 28 (±2) weeks of gestation. Outcome measures Birth outcome, maternal weight gain and neonatal anthropometry. Results The activity questionnaire was used to classify women into light, moderate and heavy activity categories. Maternal activity did not influence the incidence of prematurity or stillbirth, or the duration of gestation. It was inversely related to maternal weight gain up to 28 weeks of gestation (p=0.002). Higher maternal activity in early, as well as mid gestation, was associated with lower mean birth weight (p=0.05 and 0.02 respectively), and smaller neonatal head circumference (p=0.005 and 0.009) and mid-arm circumference (p=0.03 and 0.01) after adjusting for the effect of major confounding factors. Conclusions The findings suggest that excessive maternal activity during pregnancy is associated with smaller fetal size in rural India. The approach described for developing an activity questionnaire has potential for adoption in other settings. Sponsorship Wellcome Trust, London, UK, and the Medical Research Council, UK.

Recent investigations have, however, demonstrated that “noncaloric” activity-related factors can induce a significant imbalance between spontaneous energy intake and energy expenditure. This is the case for short sleep duration that favors hormonal changes that increase hunger and energy intake. This agrees with our research experience demonstrating that short sleeping predicts the risk of obesity in children to a greater extent than sedentary behavior. Recent research by our team has also showed that demanding mental work promotes a substantial increase in energy intake without altering energy expenditure. In addition, our preliminary data suggest that the regular practice of school-related cognitive efforts is predictive of an increase in abdominal fat accumulation. As discussed in this paper, individual variations in brain oxygenation and its related cerebral aerobic fitness might play a role in the relationship between mental work, energy intake, and the risk of excess body weight.Keywords: sleep duration, mental work, brain oxygenation, energy intake, energy expenditure

    2007-04-01

    Erdosteine was introduced in the market as a mucolytic agent for chronic pulmonary diseases more than 10 years ago. The drug contains two blocked sulphydryl groups one of which, after hepatic metabolization and opening of the thiolactone ring, becomes available both for the mucolytic and free radical scavenging and antioxidant activity too. There are several experimental evidences which support the protective effect of erdosteine in acute injury induced by a variety of pharmacological or noxious agents, mediated by products of oxidative stress. Experimental data in animal assigned to receive the noxious agent evidence that co-treatment with erdosteine increases the tissue antioxidant enzyme activities such as superoxide dismutase, catalase and glutathione peroxidase, compared with the toxic agent alone; meanwhile erdosteine decreases the tissue level of nitric oxide, xanthine oxidase, which catalyze oxygen-free radical production. In summary, erdosteine prevents the accumulation of free oxygen radicals when their production is accelerated and increases antioxidant cellular protective mechanisms. The final result is a protective effect on tissues which reduces lipid peroxidation, neutrophil infiltration or cell apoptosis mediated by noxious agents. Recent positive clinical trials in humans seem to fulfill the impressive promises that theory and experimental research have put forward.

    In guinea pig pancreatic acini rat calcitonin gene-related peptide (CGRP) increased amylase release 2-fold, salmon calcitonin had an efficacy of only 44% of that of CGRP and (Tyr0)CGRP(28-37) and human calcitonin had no actions. (Tyr0)CGRP(28-37), but not human calcitonin, antagonized the actions of CGRP in pancreatic acini with an IC50 of 3 microM. (Tyr0)CGRP(28-37) produced a parallel rightward shift in the dose-response curve for CGRP-stimulated amylase secretion. The inhibition was specific for CGRP and was reversible. Studies with 125I-CGRP demonstrated that CGRP, salmon calcitonin and (Tyr0)CGRP, but not human calcitonin, interacted with CGRP receptors on pancreatic acini. These results indicate that various CGRP-related peptides demonstrate different relationships between their abilities to occupy the CGRP receptor and to affect biologic activity, with CGRP itself being a full agonist, salmon calcitonin a partial agonist, (Tyr0)CGRP(28-37) a competitive antagonist, and human calcitonin having no actions.

    Relatively little research attention has been devoted to understanding the mechanisms through which the advising relationship functions as a medium for fostering doctoral students' development as researchers. Adapting Lent and Lopez's (2002) model of relational efficacy, we examined three types of efficacy beliefs (self-efficacy, other-efficacy, and relation-inferred self-efficacy) in relation to the advisory working alliance and the prediction of doctoral students' research interest and productivity. Gelso's (1993) concept of the research training environment was also included in model testing to capture a view of the advisory relationship as existing within a larger program training context. Participants were 274 doctoral students in a variety of academic fields. The results suggested that a slightly revised version of the hypothesized model produced good fit to the data. In particular, controlling for year in the graduate program, we found the advisory working alliance was linked to students' research self-efficacy indirectly via relation-inferred self-efficacy (i.e., students' beliefs about how their advisors viewed their research capabilities). Students' self-efficacy was, in turn, predictive of their interest in and productivity at research. We discuss the implications of these findings for future research and the practice of advising and research training. PsycINFO Database Record (c) 2014 APA, all rights reserved.

    NKS research work during the years 2002-2005 and its results have been evaluated against a set of criteria defined by the NKS Board. The evaluation encompassed the NKS-R (reactor safety) and NKS-B (emergency preparedness) programs and was conducted by two persons per program. The mode of work of the two evaluation teams was adapted to the special conditions of the program at hand, one being aimed more at the nuclear industry and the other at a more academic surrounding; in both cases, however, with great involvement of relevant national authorities. The findings of the evaluators are presented in this report. Financing and participating organizations, end users, deliverables, quality aspects, cost-benefit issues, time schedules, budgets and related issues are discussed. Finally, the sections on NKS-R and NKS-B, respectively, include conclusions and recommendations for future NKS work. (au)

    To characterize physical activity levels of adults with mental retardation and identify limitations in published research. Key word searches for "mental retardation," "intellectual disability," "learning disability," or "developmental disability" combined with "physical activity" or "habitual exercise" identified articles from MEDLINE, Academic Search Elite, Psych Articles, Health Source, and SPORT Discus. This produced a total of 801 citations. Published English-language literature that quantitatively measured physical activity levels of adults with mental retardation was included in this review. Fourteen articles met this criterion. Characteristics of participants, study design, outcome measures, methods of analyses, and findings in terms of percentages, step counts, and accelerometer output were extracted. Data were synthesized to identify the percentage of adults with mental retardation who met published health-related physical activity criteria and compare them with adults without mental retardation and to examine study limitations. The studies with the greatest rigor indicate that one-third of adults or fewer with mental retardation were sufficiently active to achieve health benefits. However, data are insufficient to determine whether adults with mental retardation are less active than the general community. Future research would be enhanced by including appropriately powered representative samples, by including comparison groups, by validating physical activity questionnaires, and by determining the accuracy of proxy respondents.

    Essential thrombocythemia, polycythemia vera, and myelofibrosis are rare chronic hematological malignancies known as myeloproliferative neoplasms (MPNs) and are characterized by deregulated myeloid lineage cell production, splenomegaly, and heterogeneous symptom profiles. MPN patients suffer from a significant symptom burden (eg, fatigue, depressive symptoms, early satiety) and an impaired overall quality of life (QoL). Current treatments typically include pharmacological approaches, which may come with additional side effects and may be limited by treatment-associated toxicities (ie, cytopenias). Nonpharmacological approaches such as physical activity may be beneficial for reducing symptom burden and improving QoL. To date, no studies have examined physical activity as a nonpharmacological approach in MPN patients despite preliminary evidence supporting its benefit in other hematological cancers. The purpose of this article is to (1) review the literature related to physical activity and specific hematological cancer subtypes and to (2) make suggestions for future research involving physical activity in MPN patients as a symptom management strategy. A brief review of studies examining physical activity in leukemias, lymphomas, and myelomas (excluding stem-cell transplant patients) was conducted. There is preliminary evidence to suggest that physical activity may be an effective approach to improve patient-reported outcomes (fatigue, depression, anxiety, sleep), physical fitness (cardiovascular fitness, balance, body composition), and overall QoL in other hematological cancers. Based on encouraging findings in other hematological cancers, future research should examine the feasibility and effectiveness of physical activity in MPN patients. © The Author(s) 2016.

    The goal of the U.S. Department of Energy Used Fuel Disposition’s (UFD) Deep Borehole Field Test is to drill two 5 km large-diameter boreholes: a characterization borehole with a bottom-hole diameter of 8.5 inches and a field test borehole with a bottom-hole diameter of 17 inches. These boreholes will be used to demonstrate the ability to drill such holes in crystalline rocks, effectively characterize the bedrock repository system using geophysical, geochemical, and hydrological techniques, and emplace and retrieve test waste packages. These studies will be used to test the deep borehole disposal concept, which requires a hydrologically isolated environment characterized by low permeability, stable fluid density, reducing fluid chemistry conditions, and an effective borehole seal. During FY16, Lawrence Berkeley National Laboratory scientists conducted a number of research studies to support the UFD Deep Borehole Field Test effort. This work included providing supporting data for the Los Alamos National Laboratory geologic framework model for the proposed deep borehole site, conducting an analog study using an extensive suite of geoscience data and samples from a deep (2.5 km) research borehole in Sweden, conducting laboratory experiments and coupled process modeling related to borehole seals, and developing a suite of potential techniques that could be applied to the characterization and monitoring of the deep borehole environment. The results of these studies are presented in this report.

    The bold network challenges described in ''Internet End-to-end Performance Monitoring for the High Energy and Nuclear Physics Community'' presented at PAM 2000 have been tackled by the intrepid administrators and engineers providing the network services. After less than a year, the BaBar collaboration has collected almost 100 million particle collision events in a database approaching 165TB (Tera=10{sup 12}). Around 20TB has been exported via the Internet to the BaBar regional center at IN2P3 in Lyon, France, for processing and around 40 TB of simulated events have been imported to SLAC from Lawrence Livermore National Laboratory (LLNL). An unforseen challenge has arisen due to recent events and highlighted security concerns at DoE funded labs. New rules and regulations suggest it is only a matter of time before many active performance measurements may not be possible between many sites. Yet, at the same time, the importance of understanding every aspect of the network and eradicating packet loss for high throughput data transfers has become apparent. Work at SLAC to employ passive monitoring using netflow and OC3MON is underway and techniques to supplement and possibly replace the active measurements are being considered. This paper will detail the special needs and traffic characterization of a remarkable research project, and how the networking hurdles have been resolved (or not!) to achieve the required high data throughput. Results from active and passive measurements will be compared, and methods for achieving high throughput and the effect on the network will be assessed along with tools that directly measure throughput and applications used to actually transfer data.

    A pre-requisite in the setting and enforcement of regulatory limits for exposure to thorium in the workplace is that thorium and its progeny can be accurately measured. Literature surveys have shown that the majority of thorium measurements were performed using either a radiochemical technique, such as alpha or gamma spectroscopy, or ICP-MS. For many methods. there was a separation step to isolate and pre-concentrate thorium from the sample matrix. Thorium was most commonly measured in geological matrices and industrial materials. A survey of current research activity was performed through distribution of a questionnaire to laboratories and national centres. From the rcsponses, four areas of current activity were identified: (i) development of methods for low level thorium determination, (ii) biological monitoring and metabolism of thorium, (iii) environmental monitoring for thorium, and (iv) health risks from X ray contract media. Two key areas for priority research were identified by the thorium Thematic Network: namely sample preparation methods and for traceable standards and reference materials for thorium analysis.

    This study aimed to establish whether the peak plantar pressures generated by overweight and obese school-age children during walking were associated with their objectively measured physical activity. Physical activity levels of a subset of 73 overweight/obese children from a randomized controlled trial (mean ± SD: age, 8.3 ± 1.1 yr; 47 girls; body mass index z-score, 2.7 ± 0.7) were objectively measured using accelerometers. Plantar pressure distributions were also quantified as the participants walked over a pressure platform. Pearson product moment correlation coefficients were calculated to determine the strength of the relations between the peak plantar pressures generated during walking and the physical activity levels for overweight/obese children. Peak pressures generated beneath the forefoot during walking were inversely correlated with time spent in different intensity levels of physical activity. Moderate-intensity (r = -0.321, P = 0.007), vigorous-intensity (r = -0.326, P = 0.006), and moderate- to vigorous-intensity (r = -0.342, P = 0.004) physical activity were significantly correlated with middle forefoot pressure and with lateral forefoot pressure (r = -0.248, P = 0.040; r = -0.264, P = 0.028; r = -0.267, P = 0.027, respectively). Lateral midfoot (r = -0.244, P = 0.044) and second toe (r = 0.227, P = 0.021) pressure were also significantly correlated with vigorous-intensity activity. Those children who generated higher pressures beneath their forefoot and midfoot during walking had lower levels of physical activity. Further research is required to determine the long-term effects of excessive body mass on participation in physical activity and whether the walking plantar pressure patterns associated with reduced physical activity are related to foot pain or discomfort.

    Full Text Available With the aim of bring near to the spanish academic field the european approaches of Public Relations, this article makes a compared revision of the situation of this subject and profession in Germany and Spain. This revision shows important resemblances on the use of the term “public relations”, the confusion of this subject with other communicative activities, the professional development and the problems of the field in both countries. However, it also shows that Germany has more tradition on public relations research than Spain and, therefore, it has a more extensive corpus of theories about this subject. For this reason, since important resemblances exist in other aspects, german research on public relations could be interesting for the spanish academic field both to explain the situation of public relations in Spain and to motivate theoretical development in our country.

  5. Relating the bipolar spectrum to dysregulation of behavioural activation: a perspective from dynamical modelling.

    Arno Steinacher

    Full Text Available Bipolar Disorders affect a substantial minority of the population and result in significant personal, social and economic costs. Understanding of the causes of, and consequently the most effective interventions for, this condition is an area requiring development. Drawing upon theories of Bipolar Disorder that propose the condition to be underpinned by dysregulation of systems governing behavioural activation or approach motivation, we present a mathematical model of the regulation of behavioural activation. The model is informed by non-linear, dynamical principles and as such proposes that the transition from "non-bipolar" to "bipolar" diagnostic status corresponds to a switch from mono- to multistability of behavioural activation level, rather than an increase in oscillation of mood. Consistent with descriptions of the behavioural activation or approach system in the literature, auto-activation and auto-inhibitory feedback is inherent within our model. Comparison between our model and empirical, observational data reveals that by increasing the non-linearity dimension in our model, important features of Bipolar Spectrum disorders are reproduced. Analysis from stochastic simulation of the system reveals the role of noise in behavioural activation regulation and indicates that an increase of nonlinearity promotes noise to jump scales from small fluctuations of activation levels to longer lasting, but less variable episodes. We conclude that further research is required to relate parameters of our model to key behavioural and biological variables observed in Bipolar Disorder.

    Health and environmental research relative to coal gasification conducted by Argonne National Laboratory, the Inhalation Toxicology Research Institute, and Oak Ridge National Laboratory under DOE sponsorship is summarized. The studies have focused on the chemical and toxicological characterization of materials from a range of process streams in five bench-scale, pilot-plant and industrial gasifiers. They also address ecological effects, industrial hygiene, environmental control technology performance, and risk assessment. Following an overview of coal gasification technology and related environmental concerns, integrated summaries of the studies and results in each area are presented and conclusions are drawn. Needed health and environmental research relative to coal gasification is identified.

  8. Movement-Related Sensorimotor High-Gamma Activity Mainly Represents Somatosensory Feedback

    Directory of Open Access Journals (Sweden)

    Seokyun Ryun

    2017-07-01

    Full Text Available Somatosensation plays pivotal roles in the everyday motor control of humans. During active movement, there exists a prominent high-gamma (HG >50 Hz power increase in the primary somatosensory cortex (S1, and this provides an important feature in relation to the decoding of movement in a brain-machine interface (BMI. However, one concern of BMI researchers is the inflation of the decoding performance due to the activation of somatosensory feedback, which is not elicited in patients who have lost their sensorimotor function. In fact, it is unclear as to how much the HG component activated in S1 contributes to the overall sensorimotor HG power during voluntary movement. With regard to other functional roles of HG in S1, recent findings have reported that these HG power levels increase before the onset of actual movement, which implies neural activation for top-down movement preparation or sensorimotor interaction, i.e., an efference copy. These results are promising for BMI applications but remain inconclusive. Here, we found using electrocorticography (ECoG from eight patients that HG activation in S1 is stronger and more informative than it is in the primary motor cortex (M1 regardless of the type of movement. We also demonstrate by means of electromyography (EMG that the onset timing of the HG power in S1 is later (49 ms than that of the actual movement. Interestingly, we show that the HG power fluctuations in S1 are closely related to subtle muscle contractions, even during the pre-movement period. These results suggest the following: (1 movement-related HG activity in S1 strongly affects the overall sensorimotor HG power, and (2 HG activity in S1 during voluntary movement mainly represents cortical neural processing for somatosensory feedback.

  9. Relating Nutrient Uptake And Respiration With Metabolically Active Transient Storage

    2009-12-01

    Quantification of water transient storage zones is critical to understand stream nutrient uptake, but the common method to measure transient storage parameters (based on the use of conservative solutes as hydrologic tracers) does not allow distinguishing among different transient storage compartments that contribute in different proportions to nutrient uptake. We use an alternative experimental approach, the Resazurin (Raz) “smart” tracer, which in combination with a conservative tracer is expected to give the relation between metabolically active transient storage (MATS) versus whole transient storage. Raz is a weakly fluorescent phenoxazine dye that undergoes an irreversible reduction to highly fluorescent Resorufin (hereafter referred as Rru) in the presence of aerobic respiration. We conducted a combined injection of Raz, NaCl, NH4, and PO4 in WS01 at H.J. Andrews Experimental Forest. The injection was performed during low-baseflow conditions (Qachieved plateau conditions in less than 15 hours after the injection began and recovered to pre-injection conditions 56 hours after the end of the injection. EC corrected by background conditions decreased with distance reflecting a dilution effect caused by the water gaining condition of the reach. Raz concentration increased and Rru concentration decreased along the reach reflecting the transformation of Raz to Rru with distance. The Rru to Raz ratio at surface water was correlated with instantaneous rates of net ecosystem production (NEP) measured over the whole reach. Percentage of surface water in wells during plateau ranged between 50% and 95%. Raz concentrations at wells were lower and Rru concentrations higher than those observed in adjacent surface water. The Rru to Raz ratio in the hyporheic zone was correlated to O2 consumption measured at wells. Nutrient concentrations were not available at the moment of writing this abstract but we hypothesize a correlation between nutrient uptake and Raz to Rru

    2011-03-01

    Researchers at the National Institute for Occupational Safety and Health studied mining accidents that involved a worker entangled in, struck by, or in contact with machinery or equipment in motion. The motivation for this study came from the large number of severe accidents, i.e. accidents resulting in a fatality or permanent disability, that are occurring despite available interventions. Accident descriptions were taken from an accident database maintained by the United States Department of Labor, Mine Safety and Health Administration, and 562 accidents that occurred during 2000-2007 fit the search criteria. Machine-related accidents accounted for 41% of all severe accidents in the mining industry during this period. Machinery most often involved in these accidents included conveyors, rock bolting machines, milling machines and haulage equipment such as trucks and loaders. The most common activities associated with these accidents were operation of the machine and maintenance and repair. The current methods to safeguard workers near machinery include mechanical guarding around moving components, lockout/tagout of machine power during maintenance and backup alarms for mobile equipment. To decrease accidents further, researchers recommend additional efforts in the development of new control technologies, training materials and dissemination of information on best practices.

  11. Virtual patients as activities: exploring the research implications of an activity theoretical stance.

    Science.gov (United States)

    Ellaway, Rachel H

    2014-09-01

    Virtual patients are computer-based simulators of patient encounters for the purposes of instruction, practice, and assessment. Although virtual patients have been around for some time they have yet to become part of mainstream medical education. A major reason for this would seem to be a lack of clarity as to what educational value virtual patients actually have. This paper argues that virtual patients should be seen as activities rather than artifacts and that activity theory can be used to generate different ways to frame scholarship in and around virtual patients. Drawing on the work of Leont'ev and Engeström this paper describes a range of perspectives based on the operations, actions, and objectives in and around virtual patients; the use of virtual patients to mediate activities; and the sociocultural context and the participants in virtual patient activities. This approach allows us to move beyond the 'does or does not work' discourse of much of the existing scholarship around virtual patients and, to an extent, around educational technologies as a whole. Activity perspectives, and activity theory in particular, offer new horizons for research and evaluation that address many of the limitations of intervention-based paradigms of inquiry.

    2012-02-01

    The current study examined whether punishment has direct and lasting effects on error-related brain activity, and whether this effect is larger with increasing trait anxiety. Participants were told that errors on a flanker task would be punished in some blocks but not others. Punishment was applied following 50% of errors in punished blocks during the first half of the experiment (i.e., acquisition), but never in the second half (i.e., extinction). The ERN was enhanced in the punished blocks in both experimental phases--this enhancement remained stable throughout the extinction phase. More anxious individuals were characterized by larger punishment-related modulations in the ERN. The study reveals evidence for lasting, punishment-based modulations of the ERN that increase with anxiety. These data suggest avenues for research to examine more specific learning-related mechanisms that link anxiety to overactive error monitoring.

  15. Why combine diet and physical activity in the same international research society?

    Directory of Open Access Journals (Sweden)

    Baranowski Tom

    2004-02-01

    Full Text Available Abstract Research in diet and physical activity in the U.S. started in very different traditions, with behavioral science input being uneven in their development. Investigators and policy makers in Europe have recognized the complementarity of diet and physical activity and incorporated them both under the label Public Health Nutrition. Joining these disciplines internationally offers the opportunity to benefit all, since the problems addressed are human, not specific to any one country. In regard to why combine diet and physical activity, at the biological level, there is reason to believe that diet and physical activity working in concert can remodel physiological structures and processes toward healthful ends. The diet and physical activity behaviors themselves vary in characteristics and are similar in others. The behavioral science components of these two disciplines face similar problems, and can learn from the advances made by the other, in the areas of measurement, correlates and intervention. By working together, knowledge will be enhanced from uncovering complementary and interactive relationships between diet and physical activity, and in relation to disease risks, that may result in designing more effective and efficient interventions and policies. Since the behavioral sciences are at a disadvantage in comparison to the biological sciences in terms of scientific advances and thereby capturing the popular imagination for solutions to health problems, we must redouble our efforts to enhance funding for behavioral research in regard to diet and physical activity and to make the research advances necessary to prevent the medicalizing of essentially social and behavioral problems. Nutrition and physical activity should most effectively do this together.

  19. Characteristics of urban parks associated with park use and physical activity: a review of qualitative research.

    McCormack, Gavin R; Rock, Melanie; Toohey, Ann M; Hignell, Danica

    2010-07-01

    Given that recent literature reviews on physical activity in urban parks deliberately excluded qualitative findings, we reviewed qualitative research on this topic informed by a published classification scheme based on quantitative research. Twenty-one studies met our inclusion criteria. These studies relied mainly on semi-structured interviews with individuals or in focus groups; only five studies involved in situ observation. Our synthesis aligns with previous quantitative research showing that attributes including safety, aesthetics, amenities, maintenance, and proximity are important for encouraging park use. Furthermore, our synthesis of qualitative research suggests that perceptions of the social environment entwine inextricably with perceptions of the physical environment. If so, physical attributes of parks as well as perceptions of these attributes (formed in relation to broader social contexts) may influence physical activity patterns. Both qualitative and quantitative methods provide useful information for interpreting such patterns, and in particular, when designing and assessing interventions intended to improve the amount and intensity of physical activity. 2010 Elsevier Ltd.

    Multiple small-scale projects have been undertaken to investigate advanced instrumentation solutions for safeguard measurement challenges associated with advanced fuel cycle facilities and next-generation fuel reprocessing installations. These activities are in support of the U.S. Department of Energy's Fuel Cycle Research and Development program and its Materials Protection, Accounting, and Control for Transmutation (MPACT) campaign. 1) Work was performed in a collaboration with the University of Michigan (Prof. Sara Pozzi, co-PI) to investigate the use of liquid-scintillator radiation detectors for assaying mixed-oxide (MOX) fuel, to characterize its composition and to develop advanced digital pulse-shape discrimination algorithms for performing time-correlation measurements in the MOX fuel environment. This work included both simulations and experiments and has shown that these techniques may provide a valuable approach for use within advanced safeguard measurement scenarios. 2) Work was conducted in a collaboration with Oak Ridge National Laboratory (Dr. Paul Hausladen, co-PI) to evaluate the strengths and weaknesses of the fast-neutron coded-aperture imaging technique for locating and characterizing fissile material, and as a tool for performing hold-up measurements in fissile material handling facilities. This work involved experiments at Idaho National Laboratory, using MOX fuel and uranium metal, in both passive and active interrogation configurations. A complete analysis has not yet been completed but preliminary results suggest several potential uses for the fast neutron imaging technique. 3) Work was carried out to identify measurement approaches for determining nitric acid concentration in the range of 1 – 4 M and beyond. This work included laboratory measurements to investigate the suitability of prompt-gamma neutron activation analysis for this measurement and product reviews of other commercial solutions.

    Full Text Available All analysed species of puny fruits (red currant (Ribes rubrum L variant Jonkheervan Tets, white currant (Ribes vulgare L. variant Blanka, black currant (Ribesnigrum L. variant Eva, blueberry (Vaccinium myrtilis variant Berkeley, elderberry(Sambucus nigra L. variant Sambo, hawthorn (Crataegus oxyacantha, mulberry(Morus nigra L. genotypes M152 and M047 are natural sources of anthocyanpigments and vitamin C with a high antiradical activity. Due to the fact that thehighest antiradical activity is not accompanied by the highest content of anthocyansand vitamin C in puny fruits, we suppose that the antiradical activity of plantmaterials is also connected with the presence of other compounds with antioxidantand antiradical activity. From our results follows that all studied puny fruits with ahigh antiradical activity increase the antioxidant value of human nutrition and alsoits prophylactic and medicinal effect.

    2017-01-01

    Context: Graduate medical education (GME) programs must develop curriculum to ensure scholarly activity among trainees and faculty to meet accreditation requirements and to support evidence-based medicine. Objective: Test whether research-related needs and interests varied across four groups: primary care trainees, specialty trainees, primary care faculty, and specialty faculty. Design: We surveyed a random sample of trainees and faculty in Kaiser Permanente Southern California’s GME programs. We investigated group differences in outcomes using Fisher exact and Kruskal-Wallis tests. Main Outcome Measures: Research experiences, skills, barriers, motivators, and interests in specific research skills development. Results: Participants included 47 trainees and 26 faculty (response rate = 30%). Among primary care faculty, 12 (71%) reported little or no research experience vs 1 (11%) for specialty faculty, 14 (41%) for primary care trainees, and 1 (8%) for specialty trainees (p skills also differed across groups (p skill level. Research barriers that differed across groups included other work roles taking priority; desire for work-life balance; and lack of managerial support, research equipment, administrative support, and funding. Conclusion: Faculty and trainees in primary care and specialties have differing research-related needs that GME programs should consider when designing curricula to support scholarly activity. Developing research skills of primary care faculty is a priority to support trainees’ scholarly activity. PMID:28333607

    2017-04-01

    Geographic information systems (GIS) data/methods offer good promise for public health programs including obesity-related research. This study systematically examined their applications and identified gaps and limitations in current obesity-related research. A systematic search of PubMed for studies published before 20 May 2016, utilizing synonyms for GIS in combination with synonyms for obesity as search terms, identified 121 studies that met our inclusion criteria. We found primary applications of GIS data/methods in obesity-related research included (i) visualization of spatial distribution of obesity and obesity-related phenomena, and basic obesogenic environmental features, and (ii) construction of advanced obesogenic environmental indicators. We found high spatial heterogeneity in obesity prevalence/risk and obesogenic environmental factors. Also, study design and characteristics varied considerably across studies because of lack of established guidance and protocols in the field, which may also have contributed to the mixed findings about environmental impacts on obesity. Existing findings regarding built environment are more robust than those regarding food environment. Applications of GIS data/methods in obesity research are still limited, and related research faces many challenges. More and better GIS data and more friendly analysis methods are needed to expand future GIS applications in obesity-related research.

    Background Research utilization is part of evidence-based practice referring to the process of reviewing and critiquing scientific research and applying the findings to one's own clinical practice. Many studies on research utilization have been conducted with doctors and nurses, but to our knowledge, none have been investigated amongst pharmacists. Objective To assess research utilization and its barriers among pharmacists and identify potential influencing factors. Setting Malaysia. Methods This cross-sectional survey was administered online and by mail to a convenient sample of pharmacists working in hospitals, health clinics, and retail pharmacies in rural and urban areas. Main outcome measure Pharmacists' research utilization knowledge, attitudes, and practices. Results Six hundred surveys were mailed to potential respondents, and 466 were returned (77.7% response rate). Twenty-eight respondents completed the survey online. The respondents' research utilization knowledge, attitudes, and practices were found to be moderate. Research utilization was associated with respondents' knowledge and attitude scores (P research utilization were modelled, higher educational level was associated with higher level of research utilization (P research utilization, respectively. The main reported barrier to research utilization was lack of sufficient authority to change patient care procedures. Conclusion Pharmacists' research utilization knowledge, attitudes, and practices can be improved by encouraging pharmacists to pursue higher degrees, promoting active participation in institutions' journal clubs, and introducing senior clinical pharmacist specialization.

    2012-09-01

    Implementation research has examined practice prioritization, implementation leadership, workforce development, workflow re-engineering, and practice reinforcement, but not addressed their relative importance as implementation drivers. This study investigated domains of implementation activities and correlated them to implementation success during a large national evidence-based practice implementation project. Implementation success was correlated with active leadership strategically devoted to redesigning the flow of work and reinforcing implementation through measurement and feedback. Relative attention to workforce development was negatively correlated with implementation. Active leaders should focus on redesigning the flow of work to support the implementation and on reinforcing program improvements.

  11. Early life determinants of physical activity and sedentary time: Current knowledge and future research

    2014-12-01

    Full Text Available Previous findings of the association between low birth weight and subsequent health outcomes have led to the “developmental origins of health and disease hypothesis”. Furthermore, modifiable and partly modifiable early life factors may also influence behaviors such as physical activity and sedentary behavior. The aim of the present review was to summarize the existing knowledge on early life determinants (birth weight, rapid infant weight gain, motor development and infant temperament of childhood physical activity and sedentary time, and suggest opportunities for future research based on the Mother and Child Cohort Study (MoBa. Inconsistent results have been observed when relating birth weight to later physical activity, likely explained by differences in methodology when assessing physical activity between studies. There is limited data on whether rapid weight gain in early life predicts later physical activity and few studies have examined the association between birth weight and infant weight gain with subsequent sedentary time. Motor development may be a predictor for childhood physical activity, however methodological limitations preclude firm conclusions. The association between motor development and sedentary time has rarely been examined. Conflicting results have been reported for the association between infant temperament and subsequent physical activity and sedentary time in toddlers. Finally, it is unknown whether physical activity modifies the association between birth weight, postnatal weight gain, and later health outcomes in youth. Additional research in well-characterized birth cohorts can be used to generate new knowledge on possible early life determinants of children’s and youth’s physical activity and sedentary time which may inform evidence-based public health interventions.

    Haycraft, Emma; Powell, Faye; Meyer, Caroline

    2015-01-01

    This is a two-study paper that developed a measure to assess parenting practices related to children's physical activity and explored maternal predictors of such parenting practices. Study 1: A self-report measure of parents' activity-related practices (the Parenting Related to Activity Measure) was developed, and a principal component analysis was carried out using data from 233 mothers of 4.5- to 9-year-old children. The results supported a six-factor model and yielded the following subscales: Responsibility/monitoring; Activity regulation; Control of active behaviours; Overweight concern; Rewarding parenting; and Pressure to exercise. Study 2: Mothers (N = 170) completed the Parenting Related to Activity Measure, alongside measures of eating psychopathology and compulsive exercise, to identify predictors of activity-related parenting practices. Mothers' eating psychopathology and exercise beliefs predicted activity parenting practices with their sons and daughters, but different predictors were seen for mothers of daughters versus sons. Mothers' eating and exercise attitudes are important predictors of their activity-related parenting practices, particularly with girls. Identifying early interactions around activity/exercise could be important in preventing the development of problematic beliefs about exercise, which are often a key symptom of eating disorders.

    Full Text Available Matthew S Wiggins1, Emily M Simonavice21Department of Kinesiology, University of Wisconsin-Eau Claire, Eau Claire, WI, USA; 2Florida State University, Tallahassee, FL, USAAbstract: According to recent published reports, over 12 million new cases of cancer were estimated worldwide for 2007. Estimates from 2008 predict that cancer will account for 22.8% of all deaths in the US. Another report stated 50% to 75% of cancer deaths in the US are related to smoking, poor dietary choices, and physical inactivity. A 2004 report indicated obesity and/or a sedentary lifestyle increases the risk of developing several types of cancer. Conversely, several large-scale cohort studies point to the positive relationship between physical activity and a reduction in cancer risk. In addition, research over the last few years has clearly shown cardiorespiratory benefits, increases in quality of life (QOL, and increases in physical functioning for cancer survivors who engage in exercise programs. Thus, the purpose of this review is to highlight three areas related to cancer and physical activity. First, information concerning the prevention of cancer through physical activity is addressed. Second, recent studies identifying changes in volume of oxygen uptake (VO2 and/or cardiorespiratory functioning involving exercise with cancer survivors is presented. Third, studies identifying changes in cancer survivors’ physical functional capacity and QOL are presented. Finally, a summary of the review is offered.Keywords: cancer, cardiorespiratory, exercise, physical activity, volume of oxygen (VO2
