    2010-01-01

    The Scalla/Xrootd software suite is a set of tools and suggested methods useful to build scalable, fault tolerant and high performance storage systems for POSIX-like data access. One of the most important recent development efforts has been to implement technologies able to deal with the characteristics of Wide Area Networks, and find solutions in order to allow data analysis applications to directly access remote data repositories in an efficient way. This contribution describes the current status of the various features and mechanisms implemented in the Scalla/Xrootd software suite, which allow to create and efficiently access 'global' data repositories, obtained by aggregating multiple sites through Wide Area Networks. One of these mechanisms is the ability of the clients to efficiently exploit high-latency high-throughput WANs and access remote repositories in read/write mode for analysis-like tasks. We will also discuss the possibilities of making distant data sub-repositories cooperate. The aim is to gi...

  2. Optimizing the ASC WAN: evaluating network performance tools for comparing transport protocols.

    2007-07-01

    The Advanced Simulation & Computing Wide Area Network (ASC WAN), which is a high delay-bandwidth network connection between US Department of Energy National Laboratories, is constantly being examined and evaluated for efficiency. One of the current transport-layer protocols which is used, TCP, was developed for traffic demands which are different from that on the ASC WAN. The Stream Control Transport Protocol (SCTP), on the other hand, has shown characteristics which make it more appealing to networks such as these. Most important, before considering a replacement for TCP on any network, a testing tool that performs well against certain criteria needs to be found. In order to try to find such a tool, two popular networking tools (Netperf v.2.4.3 & v.2.4.6 (OpenSS7 STREAMS), and Iperf v.2.0.6) were tested. These tools implement both TCP and SCTP and were evaluated using four metrics: (1) How effectively can the tool reach a throughput near the bandwidth? (2) How much of the CPU does the tool utilize during operation? (3) Is the tool freely and widely available? And, (4) Is the tool actively developed? Following the analysis of those tools, this paper goes further into explaining some recommendations and ideas for future work.

    Ionospheric delay is one the major sources of error in GPS positioning and navigation. This error in both pseudorange and phase ranges vary depending on the location of observation, local time, season, solar cycle and geomagnetic activity. For single-frequency receivers, this delay is usually removed using ionospheric models. Two of them are the Klobuchar, or broadcast, model and the global ionosphere map (GIM) provided by the International GNSS Service (IGS). In this paper, a three dimensional ionospheric electron (ne) density model derived from FormoSat3/COSMIC GPS Radio Occultation measurements, called the TaiWan Ionosphere Model, is used. It was used to calculate the slant total electron content (STEC) between receiver and GPS satellites to correct the pseudorange single-frequency observations. The corrected pseudorange for every epoch was used to determine a more accurate position of the receiver. Observations were made in July 2, 2011(Kp index = 0-2) in five randomly selected sites across the globe, four of which are IGS stations (station ID: cnmr, coso, irkj and morp) while the other is a low-cost single-frequency receiver located in Chungli City, Taiwan (ID: isls). It was illustrated that TEC maps generated using TWIM exhibited a detailed structure of the ionosphere, whereas Klobuchar and GIM only provided the basic diurnal and geographic features of the ionosphere. Also, it was shown that for single-frequency static point positioning TWIM provides more accurate and more precise positioning than the Klobuchar and GIM models for all stations. The average %error of the corrections made by Klobuchar, GIM and TWIM in DRMS are 3.88%, 0.78% and 17.45%, respectively. While the average %error in VRMS for Klobuchar, GIM and TWIM are 53.55%, 62.09%, 66.02%, respectively. This shows the capability of TWIM to provide a good global 3-dimensional ionospheric model.

  7. GASSST: global alignment short sequence search tool.

    2010-10-15

    The rapid development of next-generation sequencing technologies able to produce huge amounts of sequence data is leading to a wide range of new applications. This triggers the need for fast and accurate alignment software. Common techniques often restrict indels in the alignment to improve speed, whereas more flexible aligners are too slow for large-scale applications. Moreover, many current aligners are becoming inefficient as generated reads grow ever larger. Our goal with our new aligner GASSST (Global Alignment Short Sequence Search Tool) is thus 2-fold-achieving high performance with no restrictions on the number of indels with a design that is still effective on long reads. We propose a new efficient filtering step that discards most alignments coming from the seed phase before they are checked by the costly dynamic programming algorithm. We use a carefully designed series of filters of increasing complexity and efficiency to quickly eliminate most candidate alignments in a wide range of configurations. The main filter uses a precomputed table containing the alignment score of short four base words aligned against each other. This table is reused several times by a new algorithm designed to approximate the score of the full dynamic programming algorithm. We compare the performance of GASSST against BWA, BFAST, SSAHA2 and PASS. We found that GASSST achieves high sensitivity in a wide range of configurations and faster overall execution time than other state-of-the-art aligners. GASSST is distributed under the CeCILL software license at http://www.irisa.fr/symbiose/projects/gassst/ guillaume.rizk@irisa.fr; dominique.lavenier@irisa.fr Supplementary data are available at Bioinformatics online.

    Full Text Available LoRaWAN is a flagship Low-Power Wide Area Network (LPWAN technology that has highly attracted much attention from the community in recent years. Many LoRaWAN end-devices, such as sensors or actuators, are expected not to be powered by the electricity grid; therefore, it is crucial to investigate the energy consumption of LoRaWAN. However, published works have only focused on this topic to a limited extent. In this paper, we present analytical models that allow the characterization of LoRaWAN end-device current consumption, lifetime and energy cost of data delivery. The models, which have been derived based on measurements on a currently prevalent LoRaWAN hardware platform, allow us to quantify the impact of relevant physical and Medium Access Control (MAC layer LoRaWAN parameters and mechanisms, as well as Bit Error Rate (BER and collisions, on energy performance. Among others, evaluation results show that an appropriately configured LoRaWAN end-device platform powered by a battery of 2400 mAh can achieve a 1-year lifetime while sending one message every 5 min, and an asymptotic theoretical lifetime of 6 years for infrequent communication.

    2015-12-01

    Detecting tools in surgical videos is an important ingredient for context-aware computer-assisted surgical systems. To this end, we present a new surgical tool detection dataset and a method for joint tool detection and pose estimation in 2d images. Our two-stage pipeline is data-driven and relaxes strong assumptions made by previous works regarding the geometry, number, and position of tools in the image. The first stage classifies each pixel based on local appearance only, while the second stage evaluates a tool-specific shape template to enforce global shape. Both local appearance and global shape are learned from training data. Our method is validated on a new surgical tool dataset of 2 476 images from neurosurgical microscopes, which is made freely available. It improves over existing datasets in size, diversity and detail of annotation. We show that our method significantly improves over competitive baselines from the computer vision field. We achieve 15% detection miss-rate at 10(-1) false positives per image (for the suction tube) over our surgical tool dataset. Results indicate that performing semantic labelling as an intermediate task is key for high quality detection.

    2012-01-01

    The Global Precipitation Measurement (GPM) Observatory is a joint mission under the partnership by National Aeronautics and Space Administration (NASA) and the Japan Aerospace Exploration Agency (JAXA), Japan. The NASA Goddard Space Flight Center (GSFC) has the lead management responsibility for NASA on GPM. The GPM program will measure precipitation on a global basis with sufficient quality, Earth coverage, and sampling to improve prediction of the Earth's climate, weather, and specific components of the global water cycle. As part of the development process, NASA built the spacecraft (built in-house at GSFC) and provided one instrument (GPM Microwave Imager (GMI) developed by Ball Aerospace) JAXA provided the launch vehicle (H2-A by MHI) and provided one instrument (Dual-Frequency Precipitation Radar (DPR) developed by NTSpace). Each instrument developer provided a safety assessment which was incorporated into the NASA GPM Safety Hazard Assessment. Inhibit design was reviewed for hazardous subsystems which included the High Gain Antenna System (HGAS) deployment, solar array deployment, transmitter turn on, propulsion system release, GMI deployment, and DPR radar turn on. The safety inhibits for these listed hazards are controlled by software. GPM developed a "pathfinder" approach for reviewing software that controls the electrical inhibits. This is one of the first GSFC in-house programs that extensively used software controls. The GPM safety team developed a methodology to document software safety as part of the standard hazard report. As part of this process a new tool "safety inhibit time line" was created for management of inhibits and their controls during spacecraft buildup and testing during 1& Tat GSFC and at the Range in Japan. In addition to understanding inhibits and controls during 1& T the tool allows the safety analyst to better communicate with others the changes in inhibit states with each phase of hardware and software testing. The tool was very

    Reig, Paul; Gassert, Francis

    2013-04-01

    The Aqueduct Water Risk Atlas (Aqueduct) is a publicly available, global database and interactive tool that maps indicators of water related risks for decision makers worldwide. Aqueduct makes use of the latest geo-statistical modeling techniques to compute a composite index and translate the most recently available hydrological data into practical information on water related risks for companies, investors, and governments alike. Twelve global indicators are grouped into a Water Risk Framework designed in response to the growing concerns from private sector actors around water scarcity, water quality, climate change, and increasing demand for freshwater. The Aqueduct framework includes indicators of water stress, variability in supply, storage, flood, drought, groundwater, water quality and social conflict, addressing both spatial and temporal variation in water hazards. It organizes indicators into three categories of risk that bring together multiple dimensions of water related risk into comprehensive aggregated scores, which allow for dynamic weighting to capture users' unique exposure to water hazards. All information is compiled into an online, open access platform, from which decision-makers can view indicators, scores, and maps, conduct global risk assessments, and export data and shape files for further analysis. Companies can use this tool to evaluate their exposure to water risks across operations and supply chains, investors to assess water-related risks in their portfolio, and public-sector actors to better understand water security. Additionally, the open nature of the data and maps allow other organizations to build off of this effort with new research, for example in the areas of water-energy or water-food relationships. This presentation will showcase the Aqueduct Water Risk Atlas online tool and the features and functionalities it offers, as well as explain how it can be used for both private and public sector applications.

    The notion of attributing user fees to researchers for biospecimens provided by biobanks has been discussed frequently in the literature. However, the considerations around how to attribute the cost for these biospecimens and data have, until recently, not been well described. Common across most biobank disciplines are similar factors that influence user fees such as capital and operating costs, internal and external demand, and market competition. A biospecimen user fee calculator tool developed by CTRNet, a tumor biobank network, was published in 2014 and is accessible online at www.biobanking.org . The next year a survey was launched that tested the applicability of this user fee tool among a global health research biobank user base, including both cancer and noncancer biobanking. Participants were first asked to estimate user fee pricing for three hypothetical user scenarios based on their biobanking experience (estimated pricing) and then to calculate fees for the same scenarios using the calculator tool (calculated pricing). Results demonstrated variation in estimated pricing that was reduced by calculated pricing. These results are similar to those found in a similar previous study restricted to a group of Canadian tumor biobanks. We conclude that the use of a biospecimen user fee calculator contributes to reduced variation of user fees and for biobank groups (e.g., biobank networks), could become an important part of a harmonization strategy.

    This study describes the use of, and modifications and additions made to, the Global Trigger Tool (GTT) since its first release in 2003, and summarizes its findings with respect to counting and characterizing adverse events (AEs). Peer-reviewed literature up to 31st December 2014. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Two authors extracted and compiled the demographics, methodologies and results of the selected studies. Of the 48 studies meeting the eligibility criteria, 44 collected data from inpatient medical records and four from general practice records. Studies were undertaken in 16 countries. Over half did not follow the standard GTT protocol regarding the number of reviewers used. 'Acts of omission' were included in one quarter of studies. Incident reporting detected between 2% and 8% of AEs that were detected with the GTT. Rates of AEs varied in general inpatient studies between 7% and 40%. Infections, problems with surgical procedures and medication were the most common incident types. The GTT is a flexible tool used in a range of settings with varied applications. Substantial differences in AE rates were evident across studies, most likely associated with methodological differences and disparate reviewer interpretations. AE rates should not be compared between institutions or studies. Recommendations include adding 'omission' AEs, using preventability scores for priority setting, and re-framing the GTT's purpose to understand and characterize AEs rather than just counting them.

  2. The new geospatial tools: global transparency enhancing safeguards verification

    Pabian, Frank Vincent [Los Alamos National Laboratory

    2010-09-16

    This paper focuses on the importance and potential role of the new, freely available, geospatial tools for enhancing IAEA safeguards and how, together with commercial satellite imagery, they can be used to promote 'all-source synergy'. As additional 'open sources', these new geospatial tools have heralded a new era of 'global transparency' and they can be used to substantially augment existing information-driven safeguards gathering techniques, procedures, and analyses in the remote detection of undeclared facilities, as well as support ongoing monitoring and verification of various treaty (e.g., NPT, FMCT) relevant activities and programs. As an illustration of how these new geospatial tools may be applied, an original exemplar case study provides how it is possible to derive value-added follow-up information on some recent public media reporting of a former clandestine underground plutonium production complex (now being converted to a 'Tourist Attraction' given the site's abandonment by China in the early 1980s). That open source media reporting, when combined with subsequent commentary found in various Internet-based Blogs and Wikis, led to independent verification of the reporting with additional ground truth via 'crowdsourcing' (tourist photos as found on 'social networking' venues like Google Earth's Panoramio layer and Twitter). Confirmation of the precise geospatial location of the site (along with a more complete facility characterization incorporating 3-D Modeling and visualization) was only made possible following the acquisition of higher resolution commercial satellite imagery that could be correlated with the reporting, ground photos, and an interior diagram, through original imagery analysis of the overhead imagery.

    CoralWatch is a conservation organization that is based at the University of Queensland in Australia. Their development of the "Coral Health Chart" standardized the colour of corals for the further investigation of coral health and bleaching. The location of this project is in the NE part of Hong Kong in New Territories. The location faces ShenZhen, a heavily industrialized city, which is known for its pollution of the Pearl River. This area is protected by the Hong Kong Government and the WWF since 1996.Human activities have caused large amounts of greenhouse gasses to be released into the atmosphere. Carbon dioxide has caused the global temperature to rise and made ocean waters more acidic due to ocean respiration. The ocean is a carbon sink for mankind and the effect of severe acidification is negatively affecting marine life. The increase of temperature diminishes the amount of diversity of marine life; the decreasing acidity of the water has eliminated many species of shellfish and sea anemone; the increase of marine exploitation has decreased the diversity of marine life. The release of toxic waste, mainly mercury, waste and plastic products has also polluted the oceans which negatively impact coral reefs and endanger marine life.The data has been collected by observing the colours and discolouration (bleaching) of the corals of approximately 40 colonies per month. The species of coral in Hoi Ha Wan include, Favites flexuosa, Goniopora columna,Leptastrea purpurea, Lithophyllon undulatum, Pavona decussata. and Platygyra acuta (AFCD,1). The evaluation of four years of coralwatch data has shown the bleaching of hard boulder corals in Hoi Ha Wan, Hong Kong, has halted and the reefs are being to show signs of regeneration. Local marine biologists credited the improved situation of the corals to protected status of the area.

    The Internet has become an important health information resource for patients and the general public. Wikipedia, a collaboratively written Web-based encyclopedia, has become the dominant online reference work. It is usually among the top results of search engine queries, including when medical information is sought. Since April 2004, editors have formed a group called WikiProject Medicine to coordinate and discuss the English-language Wikipedia's medical content. This paper, written by members of the WikiProject Medicine, discusses the intricacies, strengths, and weaknesses of Wikipedia as a source of health information and compares it with other medical wikis. Medical professionals, their societies, patient groups, and institutions can help improve Wikipedia's health-related entries. Several examples of partnerships already show that there is enthusiasm to strengthen Wikipedia's biomedical content. Given its unique global reach, we believe its possibilities for use as a tool for worldwide health promotion are underestimated. We invite the medical community to join in editing Wikipedia, with the goal of providing people with free access to reliable, understandable, and up-to-date health information.

    The genetic characterization of wild-type measles viruses plays an important role in the description of viral transmission pathways and the verification of measles elimination. The 450 nucleotides that encode the carboxyl-terminus of the nucleoprotein (N-450) are routinely sequenced for genotype analysis. The objectives of this study were to develop improved primers and controls for RT-PCR reactions used for genotyping of measles samples and to develop a method to provide a convenient, safe, and inexpensive means to distribute measles RNA for RT-PCR assays and practice panels. A newly designed, genetically defined synthetic RNA and RNA isolated from cells infected with currently circulating genotypes were used to compare the sensitivity of primer pairs in RT-PCR and nested PCR. FTA® cards loaded with lysates of measles infected cells were tested for their ability to preserve viral RNA and destroy virus infectivity. A new primer pair, MeV216/MeV214, was able to amplify N-450 from viruses representing 10 currently circulating genotypes and a genotype A vaccine strain and demonstrated 100-fold increased sensitivity compared to the previously used primer set. A nested PCR assay further increased the sensitivity of detection from patient samples. A synthetic positive control RNA was developed that produced PCR products that are distinguishable by size from PCR products amplified from clinical samples. FTA® cards completely inactivated measles virus and stabilized RNA for at least six months. These improved molecular tools will advance molecular characterization of circulating measles viruses globally and provide enhanced quality control measures. Published by Elsevier B.V.

    Substandard traditional patent medicines may lead to global safety-related issues. Protecting consumers from the health risks associated with the integrity and authenticity of herbal preparations is of great concern. Of particular concern is quality control for traditional patent medicines. Here, we establish an effective approach for verifying the biological composition of traditional patent medicines based on single-molecule real-time (SMRT) sequencing and DNA barcoding. Yimu Wan (YMW), a classical herbal prescription recorded in the Chinese Pharmacopoeia, was chosen to test the method. Two reference YMW samples were used to establish a standard method for analysis, which was then applied to three different batches of commercial YMW samples. A total of 3703 and 4810 circular-consensus sequencing (CCS) reads from two reference and three commercial YMW samples were mapped to the ITS2 and psbA-trnH regions, respectively. Moreover, comparison of intraspecific genetic distances based on SMRT sequencing data with reference data from Sanger sequencing revealed an ITS2 and psbA-trnH intergenic spacer that exhibited high intraspecific divergence, with the sites of variation showing significant differences within species. Using the CCS strategy for SMRT sequencing analysis was adequate to guarantee the accuracy of identification. This study demonstrates the application of SMRT sequencing to detect the biological ingredients of herbal preparations. SMRT sequencing provides an affordable way to monitor the legality and safety of traditional patent medicines.

    In vitro dissolution test is an essential tool to assess the quality of herbal medicinal products in the solid dosage forms for oral use. Our work aimed to evaluate the dissolution behavior of Er-Zhi-Wan, in the formulations of water-honeyed pill and formula granule. Different media (water, 30% EtOH, 0.1 M HCl, acetate buffer, pH 4.5 and phosphate buffer, pH 6.8) were used following United States Pharmacopoeia and Chinese Pharmacopeia. An ultra-high performance liquid chromatography method was developed and validated to detect simultaneously six active ingredients for quantification and dissolution study (salidroside, specnuezhenide, nuezhenoside, luteolin, apigenin, oleanolic acid). As we observed, contents of main active ingredients were close in the two formulations for daily dose. In each medium, more ingredients dissolved from formula granule with higher Ymax and Ka. The mean dissolution time of the most ingredients in granule was significantly shorter than that in pill in acetate buffer, pH 4.5 and phosphate buffer, pH 6.8. Furthermore, salidroside, specnuezhenide and luteolin dissolved more than 80% in 30 min from formula granule, which indicated higher solubility along the intestinal tract according to biopharmaceutics classification system. The dissolution test developed and validated was adequate for its purposes and could be applied for quality control of herbal medicine. This work also can be used to provide necessary information on absorption for its biopharmaceutical properties.

    2012-01-01

    Full Text Available Health promotion is very relevant today. There is a global acceptance that health and social wellbeing are determined by many factors outside the health system which include socioeconomic conditions, patterns of consumption associated with food and communication, demographic patterns, learning environments, family patterns, the cultural and social fabric of societies; sociopolitical and economic changes, including commercialization and trade and global environmental change. In such a situation, health issues can be effectively addressed by adopting a holistic approach by empowering individuals and communities to take action for their health, fostering leadership for public health, promoting intersectoral action to build healthy public policies in all sectors and creating sustainable health systems. Although, not a new concept, health promotion received an impetus following Alma Ata declaration. Recently it has evolved through a series of international conferences, with the first conference in Canada producing the famous Ottawa charter. Efforts at promoting health encompassing actions at individual and community levels, health system strengthening and multi sectoral partnership can be directed at specific health conditions. It should also include settings-based approach to promote health in specific settings such as schools, hospitals, workplaces, residential areas etc. Health promotion needs to be built into all the policies and if utilized efficiently will lead to positive health outcomes.

  20. Network analytical tool for monitoring global food safety highlights China.

    Directory of Open Access Journals (Sweden)

    Tamás Nepusz

    Full Text Available BACKGROUND: The Beijing Declaration on food safety and security was signed by over fifty countries with the aim of developing comprehensive programs for monitoring food safety and security on behalf of their citizens. Currently, comprehensive systems for food safety and security are absent in many countries, and the systems that are in place have been developed on different principles allowing poor opportunities for integration. METHODOLOGY/PRINCIPAL FINDINGS: We have developed a user-friendly analytical tool based on network approaches for instant customized analysis of food alert patterns in the European dataset from the Rapid Alert System for Food and Feed. Data taken from alert logs between January 2003-August 2008 were processed using network analysis to i capture complexity, ii analyze trends, and iii predict possible effects of interventions by identifying patterns of reporting activities between countries. The detector and transgressor relationships are readily identifiable between countries which are ranked using i Google's PageRank algorithm and ii the HITS algorithm of Kleinberg. The program identifies Iran, China and Turkey as the transgressors with the largest number of alerts. However, when characterized by impact, counting the transgressor index and the number of countries involved, China predominates as a transgressor country. CONCLUSIONS/SIGNIFICANCE: This study reports the first development of a network analysis approach to inform countries on their transgressor and detector profiles as a user-friendly aid for the adoption of the Beijing Declaration. The ability to instantly access the country-specific components of the several thousand annual reports will enable each country to identify the major transgressors and detectors within its trading network. Moreover, the tool can be used to monitor trading countries for improved detector/transgressor ratios.

    Full Text Available Jing Wan Hong ointment contains 30 kinds of Chinese herbs, with functions of activating blood circulation to disperse blood stasis, clearing heat, eliminating dampness, and reducing swelling by detoxification. Therefore, Jing Wan Hong ointment may facilitate the healing of ulcers. The aim of this study was to evaluate the efficacy and mechanisms of Jing Wan Hong ointment for healing diabetic foot ulceration in Wistar rats induced by streptozotocin and sciatic nerve damage. The results showed that Jing Wan Hong ointment had a marked effect on foot ulcers in diabetic rats induced by initial nerve injury. These effects were manifested by reducing the foot ulcer size and Wagner grade after seven days of treatment. The diabetic rats with foot ulcers were almost healed after 21 days of treatment. Moreover, the mechanisms of this effect seem to be dependent on increased expression of PDGF mRNA, but there was no influence on the expression of TGF-β, VEGF, and FLT-1 mRNA.

    The emergence of low-cost connected devices is enabling a new wave of sensorization services. These services can be highly leveraged in industrial applications. However, the technologies employed so far for managing this kind of system do not fully cover the strict requirements of industrial networks, especially those regarding energy efficiency. In this article a novel paradigm, called Low-Power Wide Area Networking (LP-WAN), is explored. By means of a cellular-type architecture, LP-WAN-based solutions aim at fulfilling the reliability and efficiency challenges posed by long-term industrial networks. Thus, the most prominent LP-WAN solutions are reviewed, identifying and discussing the pros and cons of each of them. The focus is also on examining the current deployment state of these platforms in Spain. Although LP-WAN systems are at early stages of development, they represent a promising alternative for boosting future industrial IIoT (Industrial Internet of Things) networks and services.

    Transgender (trans) activists and global health partners have collaborated to develop new tools and guidance for assessing and addressing HIV and other health needs within trans populations. Trans women experience a heavy burden of HIV and other sexually transmitted infections (STIs), high incidence of violence and difficulties accessing gender-affirming services. At the same time, little has been published on trans men's health, HIV issues, needs and experiences. Young trans people are especially marginalized and vulnerable, with few programmes and services specifically tailored to their needs. Trans-specific data and guidance are needed to adapt the global response to HIV to meet the needs of the trans population. While the needs of this group have only recently received attention, global, regional and other technical guidance documents are being developed to address these gaps. Regional blueprints for comprehensive care for trans people in Latin America, the Caribbean, and Asia and the Pacific are now available. These tools - supported by the Pan American Health Organization, World Health Organization, US President's Emergency Plan for AIDS Relief and the United Nations Development Programme, in collaboration with regional trans groups - provide a contextual map, indicating opportunities for interventions in health, HIV, violence, stigma and discrimination, social protection and human rights. Global guidance includes the World Health Organization's Policy Brief: Transgender People and HIV, and the interagency publication, Implementing Comprehensive HIV and STI Programmes with Transgender People. Community empowerment and capacity building are the focus of the new tools for global and regional transgender guidance. The goal is to strengthen and ensure community-led responses to the HIV challenge in trans populations. This article describes the new tools and guidance and considers the steps needed to use them to appropriately support and engage transgender

    2014-12-01

    Teaching global change is one of the great pedagogical challenges of our day because real understanding entails integrating a variety of concepts from different scientific subject areas, including chemistry, physics, and biology, with a variety of causes and impacts in the past, present, and future. With the adoption of the Next Generation Science Standards, which emphasize climate change and other human impacts on natural systems, there has never been a better time to provide instructional support to educators on these topics. In response to this clear need, the University of California Museum of Paleontology, in collaboration with the National Center for Science Education, developed a new web resource for teachers and students titled "Understanding Global Change" (UGC) that introduces the drivers and impacts of global change. This website clarifies the connections among deep time, modern Earth system processes, and anthropogenic influences, and provides K-16 instructors with a wide range of easy-to-use tools, strategies, and lesson plans for communicating these important concepts regarding global change and the basic Earth systems processes. In summer 2014, the UGC website was field-tested during a workshop with 25 K-12 teachers and science educators. Feedback from participants helped the UGC team develop and identify pedagogically sound lesson plans and instructional tools on global change. These resources are accessible through UGC's searchable database, are aligned with NGSS and Common Core, and are categorized by grade level, subject, and level of inquiry-based instruction (confirmation, structured, guided, open). Providing a range of content and tools at levels appropriate for teachers is essential because our initial needs assessment found that educators often feel that they lack the content knowledge and expertise to address complex, but relevant global change issues, such as ocean acidification and deforestation. Ongoing needs assessments and surveys of

  11. Warehousing in the Global Supply Chain Advanced Models, Tools and Applications for Storage Systems

    CERN Document Server

    2012-01-01

    With increased globalization and offshore sourcing, global supply chain management is becoming an important issue for many businesses as it involves a company's worldwide interests and suppliers rather than simply a local or national orientation. The storage systems significantly affect the level of quality of products, the customer’s service level, and the global logistic cost. The mission of warehousing systems design, control and optimization is to effectively ship products in the right place, at the right time, and in the right quantity (i.e. in any configuration) without any damages or alterations, and minimizing costs. Warehousing in the Global Supply Chain presents and discusses a set of models, tools and real applications, including a few case studies rarely presented with a sufficient detail by other literature, to illustrate the main challenges in warehousing activities. This includes all warehouse operations (from receiving to shipping), problems and issues (e.g. storage allocation, assignment,...

    Global software development (GSD) which is a growing trend in the software industry is characterized by a highly distributed environment. Performing software project management (SPM) in such conditions implies the need to overcome new limitations resulting from cultural, temporal and geographic separation. The aim of this research is to discover and classify the various tools mentioned in literature that provide GSD project managers with support and to identify in what way they support group interaction. A systematic mapping study has been performed by means of automatic searches in five sources. We have then synthesized the data extracted and presented the results of this study. A total of 102 tools were identified as being used in SPM activities in GSD. We have classified these tools, according to the software life cycle process on which they focus and how they support the 3C collaboration model (communication, coordination and cooperation). The majority of the tools found are standalone tools (77%). A small number of platforms (8%) also offer a set of interacting tools that cover the software development lifecycle. Results also indicate that SPM areas in GSD are not adequately supported by corresponding tools and deserve more attention from tool builders.

    2015-05-01

    Full Text Available Establishing the effective mechanism of the Russian nanoindustry functioning by means of globalization benefits is one of the most important factors of raising the national economy competitiveness in the context of transition to a new technological way. Nanotechnologies is one of the key factors of this new way. The mechanism of nanoindustrial development of the Russian Federation caused by globalization is characterized in the article as a way of task-oriented implementation and management of the global nanotechnology industry development on the basis of cooperation of entities at different levels of the global economic system using the appropriate methods, tools, resources and communication channels, factors and capitals. The mechanism aims at adjusting the described contradictions faced by Russian entities in their business activities in the sphere of production, consumption and promotion of nanotechnologies, nanogoods and nanoservices. Within the framework of a theoretical research the author proposes the classification of methods and tools for the development of the Russian nanoindustry through the international cooperation by the criteria of economic functions: planning, institution, organization, management, investment, finance, information, analysis, control – all aimed at promoting the unification of concepts and actions of collaborating entities in the sphere of nanotechnology. The developed methodology of the international nanoindustrial interaction of Russian entities includes the result-oriented, institutional, organizational, budgetary, investment, tax, informative, and administrative methods, as well as analysis, audit, accounting and evaluation. Besides, the article proves the feasibility of marketing tools application in the sphere of nanoindustrial cooperation aimed at developing a more efficient strategy of promoting products with nanofeatures to the global market.

  18. Global cities rankings. A research agenda or a neoliberal urban planning tool?

    Directory of Open Access Journals (Sweden)

    Cándida Gago García

    2017-03-01

    Full Text Available This paper contains a theoretical reflection about the methodology and meaning given to the global city rankings. There is a very large academic production about the role that some cities have in global territorial processes, which has been related to the concept of global city. Many recent contributions from the mass media, advertising and consulting services must be considered also in the analysis. All of them have included new indicators in order to show the main role that cultural services have acquired in the urban economy. Also the city rankings are being used as a tool in neoliberal policies. These policies stress the position that cities have in the rankings, which are used in practices of city-branding and to justify the neoliberal decisions that are being taken. In fact, we think that rankings are used inappropriately and that it is necessary a deep and new reflection about them.

    Full Text Available The emergence of low-cost connected devices is enabling a new wave of sensorization services. These services can be highly leveraged in industrial applications. However, the technologies employed so far for managing this kind of system do not fully cover the strict requirements of industrial networks, especially those regarding energy efficiency. In this article a novel paradigm, called Low-Power Wide Area Networking (LP-WAN, is explored. By means of a cellular-type architecture, LP-WAN–based solutions aim at fulfilling the reliability and efficiency challenges posed by long-term industrial networks. Thus, the most prominent LP-WAN solutions are reviewed, identifying and discussing the pros and cons of each of them. The focus is also on examining the current deployment state of these platforms in Spain. Although LP-WAN systems are at early stages of development, they represent a promising alternative for boosting future industrial IIoT (Industrial Internet of Things networks and services.

    Full Text Available Transgender (trans activists and global health partners have collaborated to develop new tools and guidance for assessing and addressing HIV and other health needs within trans populations. Trans women experience a heavy burden of HIV and other sexually transmitted infections (STIs, high incidence of violence and difficulties accessing gender-affirming services. At the same time, little has been published on trans men's health, HIV issues, needs and experiences. Young trans people are especially marginalized and vulnerable, with few programmes and services specifically tailored to their needs. Trans-specific data and guidance are needed to adapt the global response to HIV to meet the needs of the trans population. While the needs of this group have only recently received attention, global, regional and other technical guidance documents are being developed to address these gaps. Regional blueprints for comprehensive care for trans people in Latin America, the Caribbean, and Asia and the Pacific are now available. These tools – supported by the Pan American Health Organization, World Health Organization, US President's Emergency Plan for AIDS Relief and the United Nations Development Programme, in collaboration with regional trans groups – provide a contextual map, indicating opportunities for interventions in health, HIV, violence, stigma and discrimination, social protection and human rights. Global guidance includes the World Health Organization's Policy Brief: Transgender People and HIV, and the interagency publication, Implementing Comprehensive HIV and STI Programmes with Transgender People. Community empowerment and capacity building are the focus of the new tools for global and regional transgender guidance. The goal is to strengthen and ensure community-led responses to the HIV challenge in trans populations. This article describes the new tools and guidance and considers the steps needed to use them to appropriately support and

    Global adjoint tomography is computationally expensive, requiring thousands of wavefield simulations and massive data processing. Though a collaboration with the Oak Ridge National Laboratory computing group and an allocation on the `Titan' GPU-accelerated supercomputer, we have begun to assimilate waveform data from more than 4,000 earthquakes, from 1995 to 2015, in our inversions. However, since conventional file formats and signal processing tools were not designed for parallel processing of massive data volumes, use of such tools in high-resolution global inversions leads to major bottlenecks. To overcome such problems and allow for continued scientific progress, we designed the Adaptive Seismic Data Format (ASDF) and developed a set of processing tools based on ASDF, covering from signal processing (pytomo3d), time window selection (pyflex) to adjoint source (pyadjoint). These new tools greatly enhance the reproducibility and accountability of our research while taking full advantage of parallel computing, showing superior scaling on modern computational platforms. The entire inversion workflow, intrinsically complex and sensitive to human errors, is carefully handled and automated by modern workflow management tools, preventing data contamination and saving a huge amount of time. Our starting model GLAD-M15 (Bozdag et al., 2016), an elastic model with transversely isotropic upper mantle, is based on 253 earthquakes and 15 nonlinear conjugate gradient iterations. We have now completed source inversions for more than 1,000 earthquakes and have started structural inversions using a quasi-Newton optimization algorithm. We will discuss the challenges of large-scale workflows on HPC systems, the solutions offered by our new adjoint tomography tools, and the initial tomographic results obtained using the new expanded dataset.

  5. The Nurses' Global Assessment of Suicide Risk (NGASR): developing a tool for clinical practice.

    Science.gov (United States)

    Cutcliffe, J R; Barker, P

    2004-08-01

    Contemporary and established literature indicates that people with mental health problems are at a higher risk of suicide than the general population. Because suicide is a multifaceted, complex phenomenon, risk assessment within the mental health care system requires a pluralistic, multidimensional and multiprofessional response. While assessment tools may provide useful guidance, especially guarding against complacency and over confidence, the fundamental basis of risk assessment must involve a thorough examination of the personal, interpersonal and social circumstances of each individual. Such thorough and rigorous assessments, the authors of this paper would add, require a degree of 'clinical judgement'. As a rule, inexperienced members of mental health care staff should not be charged with the responsibility of conducting suicide risk assessments without sound mentorship. However, with the right support and assessment tool, the novice practitioner might develop the kind of clinical judgement necessary for this critical task. Accordingly, this paper traces the development of the Nurses' Global Assessment of Suicide Risk (NGASR). It illustrates the practice development context out of which the need for the tool arose; it outlines the key evidence that underpins the construction of the tool and it is described. It is important to point out that as yet, no wide scale, quantitative validation of the tool has been conducted. Therefore, at this point, the tool should be treated with a degree of appropriate caution. Nevertheless, the preliminary attempts that have been made to 'validate' or 'rate' the tool in practice are included. While acknowledging that any risk assessment tool represents only one aspect of the necessarily broader assessment of risk, the NGASR appears to provide a useful template for the nursing assessment of suicide risk, especially for the novice.

    Rapid and simple access to added-value natural hazard and disaster risk information is a key issue for various stakeholders of the development and disaster risk management (DRM) domains. Accessing available data often requires specialist knowledge of heterogeneous data, which are often highly technical and can be difficult for non-specialists in DRM to find and exploit. Thus, availability, accessibility and processing of these information sources are crucial issues, and an important reason why many development projects suffer significant impacts from natural hazards. The World Bank's Global Facility for Disaster Reduction and Recovery (GFDRR) is currently developing a new open-source tool to address this knowledge gap: ThinkHazard! The main aim of the ThinkHazard! project is to develop an analytical tool dedicated to facilitating improvements in knowledge and understanding of natural hazards among non-specialists in DRM. It also aims at providing users with relevant guidance and information on handling the threats posed by the natural hazards present in a chosen location. Furthermore, all aspects of this tool will be open and transparent, in order to give users enough information to understand its operational principles. In this presentation, we will explain the technical approach behind the tool, which translates state-of-the-art probabilistic natural hazard data into understandable hazard classifications and practical recommendations. We will also demonstrate the functionality of the tool, and discuss limitations from a scientific as well as an operational perspective.

  7. Network Computing Infrastructure to Share Tools and Data in Global Nuclear Energy Partnership

    CCSE/JAEA (Center for Computational Science and e-Systems/Japan Atomic Energy Agency) integrated a prototype system of a network computing infrastructure for sharing tools and data to support the U.S. and Japan collaboration in GNEP (Global Nuclear Energy Partnership). We focused on three technical issues to apply our information process infrastructure, which are accessibility, security, and usability. In designing the prototype system, we integrated and improved both network and Web technologies. For the accessibility issue, we adopted SSL-VPN (Security Socket Layer-Virtual Private Network) technology for the access beyond firewalls. For the security issue, we developed an authentication gateway based on the PKI (Public Key Infrastructure) authentication mechanism to strengthen the security. Also, we set fine access control policy to shared tools and data and used shared key based encryption method to protect tools and data against leakage to third parties. For the usability issue, we chose Web browsers as user interface and developed Web application to provide functions to support sharing tools and data. By using WebDAV (Web-based Distributed Authoring and Versioning) function, users can manipulate shared tools and data through the Windows-like folder environment. We implemented the prototype system in Grid infrastructure for atomic energy research: AEGIS (Atomic Energy Grid Infrastructure) developed by CCSE/JAEA. The prototype system was applied for the trial use in the first period of GNEP.

    Ionospheric delay is the mainly error source in Global Navigation Satellite System (GNSS). Ionospheric model is one of the ways to correct the ionospheric delay. The single-frequency GNSS users modify the ionospheric delay by receiving the correction parameters broadcasted by satellites. Klobuchar model is widely used in Global Positioning System (GPS) and COMPASS because it is simple and convenient for real-time calculation. This model is established on the observations mainly from Europe and USA. It does not describe the equatorial anomaly region. South of China is located near the north crest of the equatorial anomaly, where the ionosphere has complex spatial and temporal variation. The assessment on the validation of Klobuchar model in this area is important to improve this model. Eleven years (2003-2014) data from one GPS receiver located at Taoyuan Taiwan (121°E, 25°N) are used to assess the validation of Klobuchar model in Taiwan. Total electron content (TEC) from the dual-frequency GPS observations is calculated and used as the reference, and TEC based on the Klobuchar model is compared with the reference. The residual is defined as the difference between the TEC from Klobuchar model and the reference. It is a parameter to reflect the absolute correction of the model. RMS correction percentage presents the validation of the model relative to the observations. The residuals' long-term variation, the RMS correction percentage, and their changes with the latitudes are analyzed respectively to access the model. In some months the RMS correction did not reach the goal of 50% purposed by Klobuchar, especially in the winter of the low solar activity years and at nighttime. RMS correction did not depend on the 11-years solar activity, neither the latitudes. Different from RMS correction, the residuals changed with the solar activity, similar to the variation of TEC. The residuals were large in the daytime, during the equinox seasons and in the high solar activity

    The objective of this work is to develop and validate a unified optimization algorithm for performing one-step global regression analysis of isothermal growth and survival curves for determination of kinetic parameters in predictive microbiology. The algorithm is incorporated with user-friendly graphical interfaces (GUIs) to develop a data analysis tool, the USDA IPMP-Global Fit. The GUIs are designed to guide the users to easily navigate through the data analysis process and properly select the initial parameters for different combinations of mathematical models. The software is developed for one-step kinetic analysis to directly construct tertiary models by minimizing the global error between the experimental observations and mathematical models. The current version of the software is specifically designed for constructing tertiary models with time and temperature as the independent model parameters in the package. The software is tested with a total of 9 different combinations of primary and secondary models for growth and survival of various microorganisms. The results of data analysis show that this software provides accurate estimates of kinetic parameters. In addition, it can be used to improve the experimental design and data collection for more accurate estimation of kinetic parameters. IPMP-Global Fit can be used in combination with the regular USDA-IPMP for solving the inverse problems and developing tertiary models in predictive microbiology. Published by Elsevier B.V.

    To determine whether faculty could successfully evaluate residents using a competency-based modified Milestones global evaluation tool. A program's leadership team modified a draft Surgery Milestones Working Group summative global assessment instrument into a modified Milestones tool (MMT) for local use during faculty meetings devoted to semiannual resident review. Residents were scored on 15 items spanning all competencies using an 8-point graphic response scale; unstructured comments also were solicited. Arithmetic means were computed at the resident and postgraduate year cohort levels for items and competency item sets. Score ranges (highest minus lowest score) were calculated; variability was termed "low" (range 2.0). A subset of "low" was designated "small" (1.0-1.9). Trends were sought among item, competency, and total Milestones scores. MMT correlations with examination scores and multisource (360°) assessments were explored. The success of implementing MMT was judged using published criteria for educational assessment methods. Fully accredited, independently sponsored residency. Program leaders and 22 faculty members (71% voluntary, mean 12y of experience). Twenty-six residents were assessed, yielding 7 to 13 evaluations for MMT per categorical resident and 3 to 6 per preliminary trainee. Scores spanned the entire response scale. All MMT evaluations included narrative comments. Individual resident score variability was low (96% within competencies and 92% across competencies). Subset analysis showed that small variations were common (35% within competencies and 54% across competencies). Postgraduate year cohort variability was higher (61% moderate or high within competencies and 50% across competencies). Cohort scores at the item, competency, and total score levels exhibited rising trajectories, suggesting MMT construct validity. MMT scores did not demonstrate concurrent validity, correlating poorly with other metrics. The MMT met multiple criteria for

    The unified global efforts to mitigate the high burden of vitamin and mineral deficiency, known as hidden hunger, in populations around the world are crucial to the achievement of most of the Millennium Development Goals (MDGs). We developed indices and maps of global hidden hunger to help prioritize program assistance, and to serve as an evidence-based global advocacy tool. Two types of hidden hunger indices and maps were created based on i) national prevalence data on stunting, anemia due to iron deficiency, and low serum retinol levels among preschool-aged children in 149 countries; and ii) estimates of Disability Adjusted Life Years (DALYs) attributed to micronutrient deficiencies in 136 countries. A number of countries in sub-Saharan Africa, as well as India and Afghanistan, had an alarmingly high level of hidden hunger, with stunting, iron deficiency anemia, and vitamin A deficiency all being highly prevalent. The total DALY rates per 100,000 population, attributed to micronutrient deficiencies, were generally the highest in sub-Saharan African countries. In 36 countries, home to 90% of the world’s stunted children, deficiencies of micronutrients were responsible for 1.5-12% of the total DALYs. The pattern and magnitude of iodine deficiency did not conform to that of other micronutrients. The greatest proportions of children with iodine deficiency were in the Eastern Mediterranean (46.6%), European (44.2%), and African (40.4%) regions. The current indices and maps provide crucial data to optimize the prioritization of program assistance addressing global multiple micronutrient deficiencies. Moreover, the indices and maps serve as a useful advocacy tool in the call for increased commitments to scale up effective nutrition interventions. PMID:23776712

    The GEOGLAM Crop Monitor's Crop Assessment Tool was released in August 2013 in support of the GEOGLAM Crop Monitor's objective to develop transparent, timely crop condition assessments in primary agricultural production areas, highlighting potential hotspots of stress/bumper crops. The Crop Assessment Tool allows users to view satellite derived products, best available crop masks, and crop calendars (created in collaboration with GEOGLAM Crop Monitor partners), then in turn submit crop assessment entries detailing the crop's condition, drivers, impacts, trends, and other information. Although the Crop Assessment Tool was originally intended to collect data on major crop production at the global scale, the types of data collected are also relevant to the food security and rangelands monitoring communities. In line with the GEOGLAM Countries at Risk philosophy of "foster[ing] the coordination of product delivery and capacity building efforts for national and regional organizations, and the development of harmonized methods and tools", a modified version of the Crop Assessment Tool is being developed for the USAID Famine Early Warning Systems Network (FEWS NET). As a member of the Countries at Risk component of GEOGLAM, FEWS NET provides agricultural monitoring, timely food security assessments, and early warnings of potential significant food shortages focusing specifically on countries at risk of food security emergencies. While the FEWS NET adaptation of the Crop Assessment Tool focuses on crop production in the context of food security rather than large scale production, the data collected is nearly identical to the data collected by the Crop Monitor. If combined, the countries monitored by FEWS NET and GEOGLAM Crop Monitor would encompass over 90 countries representing the most important regions for crop production and food security.

    2016-01-01

    Full Text Available A quantitative analysis to identify the key geometric error elements and their coupling is the prerequisite and foundation for improving the precision of machine tools. The purpose of this paper is to identify key geometric error elements and compensate for geometric errors accordingly. The geometric error model of three-axis machine tool is built on the basis of multibody system theory; and the quantitative global sensitivity analysis (GSA model of geometric error elements is constructed by using extended Fourier amplitude sensitivity test method. The crucial geometric errors are identified; and stochastic characteristics of geometric errors are taken into consideration in the formulation of building up the compensation strategy. The validity of geometric error compensation based on sensitivity analysis is verified on a high-precision three-axis machine tool with open CNC system. The experimental results show that the average compensation rates along the X, Y, and Z directions are 59.8%, 65.5%, and 73.5%, respectively. The methods of sensitivity analysis and geometric errors compensation presented in this paper are suitable for identifying the key geometric errors and improving the precision of CNC machine tools effectively.

    The CERES SYN1deg product provides climate quality 3-hourly globally gridded and temporally complete maps of top of atmosphere, in atmosphere, and surface fluxes. This product requires efficient release to the public and validation to maintain quality assurance. The CERES team developed web-tools for the distribution of both the global gridded products and grid boxes that contain long term validation sites that maintain high quality flux observations at the Earth's surface. These are found at: http://ceres.larc.nasa.gov/order_data.php. In this poster we explore the various tools available to users to sub-set, download, and validate using surface observations the SYN1Deg and Surface-EBAF products. We also analyze differences found in long-term records from well-maintained land surface sites such as the ARM central facility and high quality buoy radiometers, which due to their isolated nature cannot be maintained in a similar manner to their land based counterparts.

    To identify and characterize adverse events (AE) in an Internal Medicine Department of a district hospital using an extension of the Global Trigger Tool (GTT), analyzing the diagnostic validity of the tool. An observational, analytical, descriptive and retrospective study was conducted on 2013 clinical charts from an Internal Medicine Department in order to detect EA through the identification of 'triggers' (an event often related to an AE). The 'triggers' and AE were located by systematic review of clinical documentation. The AE were characterized after they were identified. A total of 149 AE were detected in 291 clinical charts during 2013, of which 75.3% were detected directly by the tool, while the rest were not associated with a trigger. The percentage of charts that had at least one AE was 35.4%. The most frequent AE found was pressure ulcer (12%), followed by delirium, constipation, nosocomial respiratory infection and altered level of consciousness by drugs. Almost half (47.6%) of the AE were related to drug use, and 32.2% of all AE were considered preventable. The tool demonstrated a sensitivity of 91.3% (95%CI: 88.9-93.2) and a specificity of 32.5% (95%CI: 29.9-35.1). It had a positive predictive value of 42.5% (95%CI: 40.1-45.1) and a negative predictive value of 87.1% (95%CI: 83.8-89.9). The tool used in this study is valid, useful and reproducible for the detection of AE. It also serves to determine rates of injury and to observe their progression over time. A high frequency of both AE and preventable events were observed in this study. Copyright © 2014 SECA. Published by Elsevier Espana. All rights reserved.

    There is no method to be used as a reference standard for nutritional assessment. This study aims to develop and verify the performance of a new tool, based on the Item Response Theory (IRT), from the Subjective Global Assessment (SGA) questionnaire, in hospitalized adult patients. Retrospective cohort study, composed by secondary database, formed by patients included from October 2005 to June 2006. The new tool presented was developed through the usage of cumulative models from the IRT. Out of 1503 evaluated patients, 2/3 were randomly selected to the development sample of the new tool and 1/3 to the performance verification sample. After item adjustments, the "Nutritional Assessment Score" (NAS) was proposed, with reduced number of questions, and, in comparison to SGA, less polytomic items. NAS demonstrates association to variables that are clinically relevant (hospital mortality, long hospital stay, serum albumin and body mass index) and has shown itself to be more precise to patients with the worst degrees of nutritional status. Results point to the validation of the NAS in detecting, accurately, the nutritional status of hospitalized patients.

    2017-01-01

    Full Text Available With the advent of the Internet of Things (IoT era, we are experiencing rapid technological progress. Billions of devices are connected to each other, and our homes, cities, hospitals, and schools are getting smarter and smarter. However, to realize the IoT, several challenging issues such as connecting resource-constrained devices to the Internet must be resolved. Recently introduced Low Power Wide Area Network (LPWAN technologies have been devised to resolve this issue. Among many LPWAN candidates, the Long Range (LoRa is one of the most promising technologies. The Long Range Wide Area Network (LoRaWAN is a communication protocol for LoRa that provides basic security mechanisms. However, some security loopholes exist in LoRaWAN’s key update and session key generation. In this paper, we propose a dual key-based activation scheme for LoRaWAN. It resolves the problem of key updates not being fully supported. In addition, our scheme facilitates each layer in generating its own session key directly, which ensures the independence of all layers. Real-world experimental results compared with the original scheme show that the proposed scheme is totally feasible in terms of delay and battery consumption.

    As the saying goes, bencao is growing in specific areas. Anhui province is located in the middle and lower reaches of the Yangtze River Plain. Its north-south direction is longer than the east-west and Anhui is divided into three regions by the Yangtze River and Huaihe. It is important for the land to have plentiful traditional Chinese medicine resources, and it exists profound cultural heritage of Chinese medicine and to cluster the Dao-di herbs with a long history. The vicissitude of historical geography of Anhui province was combed, the historical basis of Anhui short as "Wan" was hackles, the prosperity and decline of Dao-di herbs in Anhui territory was sorted out in this paper. This article holds that the history of Anhui established as a province started in the Qing Dynasty, but the history of Dao-di herbs in Anhui territory has always been the same strain, Bencao can be test clearly and production areas is stable. Despite Anhui Dao-di herbs have changed in the different historical periods, its core varieties and essential elements has been inherited to today. Generally speaking, "Wan medicines" are not only collectively called the current territory of Anhui Dao-di herbs, but also include the historical period of Anhui famous Dao-di herbs.

    Lin, Zhuosheng; Yu, Simin; Li, Chengqing; Lü, Jinhu; Wang, Qianxue

    This paper proposes a chaotic secure video remote communication scheme that can perform on real WAN networks, and implements it on a smartphone hardware platform. First, a joint encryption and compression scheme is designed by embedding a chaotic encryption scheme into the MJPG-Streamer source codes. Then, multiuser smartphone communications between the sender and the receiver are implemented via WAN remote transmission. Finally, the transmitted video data are received with the given IP address and port in an Android smartphone. It should be noted that, this is the first time that chaotic video encryption schemes are implemented on such a hardware platform. The experimental results demonstrate that the technical challenges on hardware implementation of secure video communication are successfully solved, reaching a balance amongst sufficient security level, real-time processing of massive video data, and utilization of available resources in the hardware environment. The proposed scheme can serve as a good application example of chaotic secure communications for smartphone and other mobile facilities in the future.

    The Validation Network (VN) prototype for the Global Precipitation Measurement (GPM) Mission compares data from the Tropical Rainfall Measuring Mission (TRMM) satellite Precipitation Radar (PR) to similar measurements from U.S. and international operational weather radars. This prototype is a major component of the GPM Ground Validation System (GVS). The VN provides a means for the precipitation measurement community to identify and resolve significant discrepancies between the ground radar (GR) observations and similar satellite observations. The VN prototype is based on research results and computer code described by Anagnostou et al. (2001), Bolen and Chandrasekar (2000), and Liao et al. (2001), and has previously been described by Morris, et al. (2007). Morris and Schwaller (2009) describe the PR-GR volume-matching algorithm used to create the VN match-up data set used for the comparisons. This paper describes software tools that have been developed for visualization and statistical analysis of the original and volume matched PR and GR data.

    Increasing evidence demonstrates significant variation in adverse outcomes following surgery between countries. In order to better quantify these variations, we hypothesize that freely available online risk calculators can be used as a tool to generate global benchmarking of risk-adjusted surgical outcomes. This is a prospective cohort study conducted at an academic teaching hospital in South Africa (GSH). Consecutive adult patients undergoing major general or vascular surgery who met the ACS-NSQIP inclusion criteria for a 3-month period were included. Data variables required by the ACS risk calculator were prospectively collected, and patients were followed for 30 days post-surgery for the occurrence of endpoints. Calculating observed-to-expected ratios for ten outcome measures of interest generated risk-adjusted outcomes benchmarked against the ACS-NSQIP consortium. A total of 373 major general and vascular surgery procedures met the inclusion criteria. The GSH operative cohort varied significantly compared to the 2012 ACS-NSQIP database. The risk-adjusted O/E ratios were significant for any complication O/E 1.91 (95 % CI 1.57-2.31), surgical site infections O/E 4.76 (95 % CI 3.71-6.01), renal failure O/E 3.29 (95 % CI 1.50-6.24), death O/E 3.43 (95 % CI 2.19-5.11), and total length of stay (LOS) O/E 3.43 (95 % CI 2.19-5.11). Freely available online risk calculators can be utilized as tools for global benchmarking of risk-adjusted surgical outcomes.

    A global, satellite-based, terrestrial snow mission planning tool is proposed to help inform experimental mission design with relevance to snow depth and snow water equivalent (SWE). The idea leverages the capabilities of NASA's Land Information System (LIS) and the Tradespace Analysis Tool for Constellations (TAT-C) to harness the information content of Earth science mission data across a suite of hypothetical sensor designs, orbital configurations, data assimilation algorithms, and optimization and uncertainty techniques, including cost estimates and risk assessments of each hypothetical permutation. One objective of the proposed observing system simulation experiment (OSSE) is to assess the complementary or perhaps contradictory information content derived from the simultaneous collection of passive microwave (radiometer), active microwave (radar), and LIDAR observations from space-based platforms. The integrated system will enable a true end-to-end OSSE that can help quantify the value of observations based on their utility towards both scientific research and applications as well as to better guide future mission design. Science and mission planning questions addressed as part of this concept include: What observational records are needed (in space and time) to maximize terrestrial snow experimental utility? How might observations be coordinated (in space and time) to maximize this utility? What is the additional utility associated with an additional observation? How can future mission costs be minimized while ensuring Science requirements are fulfilled?

    This study uses data collected by the Kuroshio Extension Observatory (KEO) mooring during the passage of Typhoon Choi-Wan (International designation 0914) to validate numerical simulations of the typhoon-ocean interactions and their effect on carbon dioxide uptake and outgassing conducted by an atmosphere-wave-ocean coupled model incorporating a carbon equilibrium model. The eye of the typhoon passed the KEO mooring, located at 32.3○N, 144.5○E, ~40 km to the southeast on 19 September 2009. The coupled model reasonably simulated the positions of Choi-wan and variation in observed sea-level pressure, although the simulated moving speed was slower than that of the best track when the typhoon passed near the KEO buoy. The slow translation and poor oceanic initial field appeared to cause the results of lower sea-surface temperature (SST), sea-surface salinity (SSS) and oceanic partial CO2 than those of observations. Better agreement was found with the grid point south of the buoy when the eye of the typhoon passed by the buoy three hours ago, where the initial SST and SSS were higher than observations and simulated dissolved inorganic carbon were relatively high compared with that at the buoy. A difference in surface-roughness-length schemes affects sea-level pressure, air temperature and surface wind asymmetry but little effect on the values of SST, SSS and oceanic partial CO2 variations. Therefore, simulation of the sudden variation of the air-sea partial CO2 appears to be more sensitive to the typhoon track, the intensity and oceanic initial field than the effect of ocean waves.

    The ISF Academy, a school with 1500 students, is located on Kong Sin Wan Road. The majority of students from the academy commute to school every morning by private cars, school buses and other public transportation. For the past few years, the school management team has been imposing traffic management regulations to alleviate and minimize traffic congestion in the nearby area. In spite of that, traffic management on Kong Sin Wan Road is fairly limited and inadequate, resulting in congestion at the start and finish of the school day. As a school, we are dedicated to reduce and mitigate the number of private cars and school buses, as well as to control carbon dioxide emissions from the variety of vehicles. In order to implement strategies to make improvements to the current traffic management system, we, as a school, aim to establish a systematic approach to calculate and model the number of private cars, EV cars, plug-in hybrids and school buses flowing near the ISF campus every day, and the number of students on each vehicle. According to the U.S Environmental Protection Agency (EPA), the average annual carbon dioxide emission for a typical passenger vehicle is 4.7 metric tons. By multiplying the average carbon dioxide emission by the number of cars coming to campus every morning, we will gain a better understanding of the amount of carbon dioxide emitted from school vehicles. To extend the research, we will design a survey to investigate and encourage carpooling between families and students who live close, in order to combat and relieve rising traffic congestion and minimize cars crowding the roads. The traffic study project will not only help the school community create a more environment-friendly campus, but also improve the traffic congestion around the school area.

    To determine the prevalence of undernutrition in children with cerebral palsy and to compare subjective and objective methods of nutritional assessment. This was a hospital based analytical observational study in which 180 children of cerebral palsy, aged 1-12 y, attending tertiary level hospital, Jaipur from March, 2012 through March, 2013 were included. Subjective assessment was done by questionnaire (Subjective Global Nutritional Assessment; SGNA) in which questions related to nutrition history and physical examination, signs of fat, muscle wasting and edema was done while objective assessment was done by weight, height and triceps skinfold thickness (TSFT) measurements. In this study prevalence of undernutrition by subjective method (SGNA) was 76.67% while by objective measurement (weight, height, TSFT) was 48.89%, 77.78% 35.18% respectively. There was fair to moderate agreement between the SGNA and objective assessments including weight and height (k = 0.341, p = 0.000; k = 0.337, p = 0.000 respectively) while for TSFT agreement between both methods was poor (k = 0.092, p = 0.190). In the index study, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of SGNA was for weight was 95%, 37%, 56%, 90%; for height 84%, 50%, 85%, 47%; for TSFT 81%, 30%, 38%, 75% respectively. The prevalence of undernutrition is high in cerebral palsy children. SGNA can be a reliable tool for assessing nutritional status in children with cerebral palsy and is a simple, comprehensive, noninvasive, and cost-effective tool for screening undernutrition in children of cerebral palsy.

    The aim of this study was to investigate the effect of a traditional Chinese medicine, Bu-Shen-Gu-Chi-Wan, on experimental periodontitis and bone regeneration in rat. Sixty female Sprague-Dawley rats were divided equally into three groups: a healthy control group (Group N); a periodontitis group (Group P); and the Bu-Shen-Gu-Chi-Wan treatment group (Group T). A 0.2-mm wire was placed around the maxillary first molar and Porphyromonas gingivalis was injected into the gingival sulcus. Rats in different groups were administered 0.9% normal saline or Bu-Shen-Gu-Chi-Wan solution (4 g/kg of body weight, for three alternate days), and the animals were killed after 4 wk. Morphological analysis of alveolar bone rebuilding was performed using micro-computed tomography (micro-CT) and stereomicroscopy, and the variation of inflammation in the periodontium was determined histologically. The serum levels of the proinflammatory cytokines interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) and of the bone-turnover biomarkers pyridinoline cross-linked carboxyterminal telopeptide of type I collagen (ICTP) and osteocalcin (OC) were determined using radioimmunoassays. After treatment with Bu-Shen-Gu-Chi-Wan, there were significant decreases in the levels of IL-1β, TNF-α, ICTP and OC and decreased inflammatory infiltration in the periodontal tissues of Group T. significant changes in alveolar bone volume and density were detected by micro-CT, but stereomicroscopy did not detect a significant improvement of alveolar bone height. The data of the present study suggest that the traditional Chinese medicine, Bu-Shen-Gu-Chi-Wan, has anti-inflammatory function in experimental periodontitis and may simultaneously improve alveolar bone remodeling. © 2013 John Wiley & Sons A/S.

    Nutritional assessment of critically ill patients has created controversy. However, it is well established that malnourished patients who are severely ill have worse outcomes than well-nourished patients. Therefore, assessing patients' nutritional status may be useful in predicting which patients may experience increased morbidity and mortality. One hundred eighty-five consecutively admitted patients were followed until discharge or death, and their nutritional status was evaluated using Subjective Global Assessment (SGA) as well as anthropometric and laboratory methods. Agreement between the methods was measured using the Kappa coefficient. Malnutrition was highly prevalent (54%), according to SGA. Malnourished patients had significantly higher rates of readmission to the intensive care unit (ICU) (OR 2.27; CI 1.08-4.80) and mortality (OR 8.12; CI 2.94-22.42). The comparison of SGA with other tests used to assess nutritional status showed that the correlation between the methods ranged from poor to superficial. SGA, an inexpensive and quick nutritional assessment method conducted at the bedside, is a reliable tool for predicting outcomes in critically ill patients.

    2012-08-01

    Full Text Available The use of Global Navigation Satellite Systems (GNSS signals for remote sensing applications, generally referred to as GNSS-Reflectometry (GNSS-R, is gaining increasing interest among the scientific community as a remote sensing tool for land applications. This paper describes a long term experimental campaign in which an extensive dataset of GNSS-R polarimetric measurements was acquired over a crop field from a ground-based stationary platform. Ground truth ancillary data were also continuously recorded during the whole experimental campaign. The duration of the campaign allowed to cover a full crop growing season, and as a consequence of seasonal rains on the experimental area, data could be recorded over a wide variety of soil conditions. This enabled a study on the effects of different land bio-geophysical parameters on GNSS scattered signals. It is shown that significant power variations in the measured GNSS reflected signals can be detected for different soil moisture and vegetation development conditions. In this work we also propose a technique based on the combination of the reflected signal’s polarizations in order to improve the integrity of the observables with respect to nuisance parameters such as soil roughness.

    Full Text Available Stratospheric intrusion (SI events are a topic of ongoing research, especially because of their ability to change the oxidation capacity of the troposphere and their contribution to tropospheric ozone levels. In this work, a novel tool called STEFLUX (Stratosphere-to-Troposphere Exchange Flux is presented, discussed, and used to provide a first long-term investigation of SI over two global hot-spot regions for climate change and air pollution: the southern Himalayas and the central Mediterranean Basin. The main purpose of STEFLUX is to obtain a fast-computing and reliable identification of the SI events occurring at a specific location and during a specified time window. It relies on a compiled stratosphere-to-troposphere exchange (STE climatology, which makes use of the ERA-Interim reanalysis dataset from the ECMWF, as well as a refined version of a well-established Lagrangian methodology. STEFLUX results are compared to the SI observations (SIO at two high-mountain WMO/GAW global stations in these climate hot spots, i.e., the Nepal Climate Observatory-Pyramid (NCO-P, 5079 m a.s.l. and Mt. Cimone (2165 m a.s.l., which are often affected by SI events. Compared to the observational datasets at the two specific measurement sites, STEFLUX is able to detect SI events on a regional scale. Furthermore, it has the advantage of retaining additional information concerning the pathway of stratospheric-affected air masses, such as the location of tropopause crossing and other meteorological parameters along the trajectories. However, STEFLUX neglects mixing and dilution that air masses undergo along their transport within the troposphere. Therefore, the regional-scale STEFLUX events cannot be expected to perfectly reproduce the point measurements at NCO-P and Mt. Cimone, which are also affected by small-scale (orographic circulations. Still, the seasonal variability in SI events according to SIO and STEFLUX agrees fairly well. By exploiting the

    Full Text Available There are many public health benefits to cycling, such as chronic disease reduction and improved air quality. Real and perceived concerns about safety are primary barriers to new ridership. Due to limited forums for official reporting of cycling incidents, lack of comprehensive data is limiting our ability to study cycling safety and conduct surveillance. Our goal is to introduce BikeMaps.org, a new website developed by the authors for crowd-source mapping of cycling collisions and near misses. BikeMaps.org is a global mapping system that allows citizens to map locations of cycling incidents and report on the nature of the event. Attributes collected are designed for spatial modelling research on predictors of safety and risk, and to aid surveillance and planning. Released in October 2014, within two months the website had more than 14,000 visitors and mapping in 14 countries. Collisions represent 38% of reports (134/356 and near misses 62% (222/356. In our pilot city, Victoria, Canada, citizens mapped data equivalent to about one year of official cycling collision reports within two months via BikeMaps.org. Using report completeness as an indicator, early reports indicate that data are of high quality with 50% being fully attributed and another 10% having only one missing attribute. We are advancing this technology, with the development of a mobile App, improved data visualization, real-time altering of hazard reports, and automated open-source tools for data sharing. Researchers and citizens interested in utilizing the BikeMaps.org technology can get involved by encouraging citizen mapping in their region.

    The implementing of the WHO Surgical Safety Checklist (SSC) has helped to improve patient safety. The aim of this study was to assess the level of compliance of the SSC, and incorporating the non-compliances as «triggers» in the Global Trigger Tool (GTT). Acute Geriatric Hospital (200 beds). Retrospective study, study period: 2011-2014. The SSC formulary and the methodology of the GTT were used for the analysis of electronic medical records and the compliance with the SSC. The NCCP MERP categories were used to assess the severity of the harm. Out of all the electronic medical records (EMR), a total of 227 (23.6%) discharged patients (1.7% of interventions in the four year study period) were analysed. All (100%) of the EMR included the SSC, with 94.4% of the items being completed, and 28.2% of SSC had all items completed in the 3 phases of the process. Surgical adverse events decreased from 16.3% in 2011 to 9.4% in 2014 (P=.2838, not significant), and compliance with all items of SSC was increased from 18.6% to 39.1% (P=.0246, significant). The GTT systematises and evaluates, at low cost, the triggers and incidents/ AEs found in the EMR in order to assess the compliance with the SSC and consider non-compliance of SSC as «triggers» for further analysis. This strategy has never been referred to in the GTT or in the SCC formulary. Copyright © 2016 SECA. Published by Elsevier Espana. All rights reserved.

    Nutritional risk and malnutrition are highly prevalent among hospitalized patients. As a result, several methods have been developed to produce an adequate nutritional diagnosis. We aimed to assess the relationship between nutritional risk tools and parameters derived from bioelectrical impedance analysis with a Subjective Global Assessment (SGA). A cross-sectional study was conducted from April to September 2010. The study included 124 patients admitted to the Surgical Clinic I, University Hospital, Federal University of Santa Catarina, Florianópolis, Brazil, to undergo elective surgery. We utilized SGA and Nutritional Risk Screening 2002 (NRS 2002), Nutritional Risk Index (NRI), Fat-Free Mass Index (FFMI), Fat Mass Index (FMI), body cell mass as a percentage of the total weight (%BCM), and standardized phase angle (SPA). The agreement was tested by κ coefficient, while bivariate associations were tested by Mann-Whitney U test. Prevalence of nutritional risk by NRS 2002 and NRI or malnutrition by SGA, FFMI, FMI, %BCM, and SPA was 19.3%, 69.5%, 35.5%, 12.9%, 8.1%, 46.8%, and 4.8%, respectively. The best agreement was between SGA and NRS 2002 (κ=.490), possibly because they constitute similar instruments. Patients identified as malnourished by SGA (B+C) showed considerably lower values of FFMI, FMI, BCM, and SPA. The results suggest that the NRS 2002 and parameters derived from bioelectrical impedance analysis identify patients with impaired nutritional status.

    Mouden, Youssef

    the model in its current state has revealed that it is a promising tool both in the uniform and zoomed configurations. The surface temperatures show the expected behavior regarding the diurnal variation and the changes related to the season and dust amount. The boundary layer profiles reflect the known features of the Martian boundary layer and the vertical profiles of temperature give a proper thermal structure. The zonal averages show a reasonable global meridional circulation and a good agreement with simulations from other models, especially in the mass streamfunction values that reflect the Hadley circulation. The agreement with the Thermal Emission Spectrometer temperature profiles is also encouraging. An important asset of this model is its ability to perform high resolution simulations over a limited area while remaining a global model. This feature has been tested in two cases: over Pavonis Mons which is the middle volcano of the Tharsis Montes volcanoes and in the Viking 1 landing site in the Chryse Planitia region. Both cases give satisfactory results. The simulated air flow near Pavonis Mons shows clearly the volcano's dynamical and thermal effects. The overall simulated meteorological conditions and the time series of the measurements made by the Viking instruments show a reasonable and encouraging accord.

  2. Application of TaiWan Ionosphere Model to Single-Frequency Ionospheric Delay Correction for GPS Static Position Positioning

    Macalalad, E. P.; Tsai, L.; Wu, J.

    2011-12-01

    Ionospheric delay is one of the major sources of error in GPS positioning and navigation. This error in both pseudorange and phase ranges can vary depending on the location of observation, local time, season, solar cycle and geomagnetic activity. This effect can be practically removed using dual-frequency receivers. However, these types of receivers are very expensive and thus, impractical for most users. Therefore, for single-frequency receivers, ionosphere is usually modeled to attempt to remove this effect analytically. Numerous ionosphere models have been introduced in the past. Some of which are the Klobuchar (or broadcast) model and the global ionosphere map (GIM) provided by the International GNSS Service (IGS). In this paper, another model, called the TaiWan Ionosphere Model (TWIM) was used to correct this effect. TWIM is a three dimensional ionospheric electron (ne) density model derived from FormoSat3/COSMIC GPS Radio Occultation measurements, was used to calculate ionospheric delay for GPS single-frequency positioning. The ne profiles were used to calculate the slant TEC (STEC) between a receiver and each GPS satellite and correct the pseudorange single-frequency observations. The corrected pseudorange for every epoch was used to calculate the position of the receiver. Observations were made in a low-latitude location near one of the peaks of the equatorial anomaly. It was shown that TEC maps generated using TWIM exhibited detailed structure of the ionosphere, whereas Klobuchar and GIM only provided the basic diurnal and geographic features of the ionosphere. Also, it was shown that for static point positioning TWIM provides more accurate and more precise positioning than the Klobuchar and GIM models. That is, on the average, the horizontal accuracy, represented by the circular error probable (CEP), distance RMS (DRMS) and twice the DRMS (2DRMS), were better by 15-18% as compared with the CEP, DRMS and 2DRMS of uncorrected, Klobuchar and GIM.

    Over the past several decades, as the pace of globalization has accelerated, operational issues of international coordination have often been overlooked.  For example, the global financial crisis that began in 2007 is attributed, in part, to a lack of regulatory oversight.  As a result, supranational organizations, such as the G-20, the World Bank, and the International Monetary Fund, have prioritized strengthening of the international financial architecture and providing opportunities for dialogue on national policies, international co-operation, and international financial institutions. Prevailing characteristics of the global economic systems, such as the increasing power of financial institutions, changes in the structure of global production, decline in the authority of nation-states over their national economy, and  creation of global institutional setting, e.g., global governance have created the conditions for a naturally evolving process towards enabling national epistemic communities to create in...

    To study the metabolism of berberine and palmatine in prescription compatibility of Wuji Wan in human intestinal flora. The L9 (3(4)) orthogonal design was adopted to compare prescription compatibility of nine groups of Wuji Wan composed of Coptis chinensis, Evodiae and fried Radix paeoniae alba into and single ingredient of C. chinensis. They were cultivated with fresh human excrements under anaerobic conditions for 24 h. A HPLC-UV method was adopted for determining berberine and palmatine in bacteria culture medium, in order to compare the metabolism of the two components in different prescription compatibility. Metabolism of berberine was positively correlated with doses, whereas metabolism of palmatine was negatively correlated with doses in extracts from C. chinensis. Compound compatibility speeded up the metabolism of berberine in low dose, which was positively related to the doses of Evodiae and fried Paeoniae Alba Radix; meanwhile Compound compatibility slowed down the metabolism of berberine in high dose, which was negatively related to the dose of Evodiae. Compound compatibility speeded up the metabolism of palmatine in high dose, which was negatively related to the doses of Evodiae and fried Paeoniae Alba Radix. The metabolism of the compatibility of Wuji Wan speeds up, when Coptis chinensis components metabolite rapidly in intestinal flora; while the metabolism of the compatibility of Wuji Wan slows down, when C. chinensis components metabolite slowly in intestinal flora. Therefore, they show a balanced effect. Additionally, different proportion of C. chinensis, Evodiae and fried Paeoniae Alba Radix cause difference in metabolism speed of berberine and palmatine to some extent.

    The traditional Chinese medicine You-Gui-Wan (YGW) contains ten species of medicinal plants and has been used to improve health in remissive states of asthma for hundreds of years in Asia. However, little is known about the immunomodulatory mechanisms in vivo. Therefore, this study investigated the pathologic and immunologic responses to YGW in mice that had been repeatedly exposed to Dermatogoides-pteronyssinus (Der p). YGW reduced Der-p-induced airway hyperresponsiveness and total IgE in serum. It also inhibited eosinophil infiltration by downregulating the protein expression of IL-5 in serum and changed the Th2-bios in BALF by upregulating IL-12. Results of the collagen assay and histopathologic examination showed that YGW reduced airway remodeling in the lung. In addition, after YGW treatment there was a relative decrease in mRNA expression of TGF-β1, IL-13, eotaxin, RANTES, and MCP-1 in lung in the YGW group. The results of EMSA and immunohistochemistry revealed that YGW inhibited NF-κB expression in epithelial lung cells. YGW exerts its regulative effects in chronic allergic asthmatic mice via its anti-inflammatory activity and by inhibiting the progression of airway remodeling.

    Full Text Available Jiao Tai Wan (JTW, a Chinese herbal formula containing Rhizoma Coptidis and Cortex Cinnamomi, has been used for diabetic treatment for many years. The aim of this study was to determine the main components in JTW and to investigate the effects of JTW on hepatic lipid accumulation in diabetic rats and humans. JTW extract was prepared and the main components were assayed by HPLC. An animal model of diabetes mellitus was established and JTW was administered intragastrically. In the clinical study, diabetic patients with poor glycemic control were treated with JTW. Blood glucose and lipid parameters, liver histology, hepatic triglyceride content and lipogenic gene expression were examined. Our data demonstrated that JTW significantly improved hyperglycemia, hyperlipidemia and hepatic lipid accumulation in diabetic rats. This was accompanied by the down-regulation of acetyl coenzyme A carboxylase (ACC and fatty acid synthase (FAS protein expressions, and the up-regulation of AMP-activated protein kinase (AMPK and phosphorylated-ACC (pACC protein expressions in the liver tissues. Diabetic patients also exhibited decreases in their hepatic triglyceride content. The results suggest that JTW attenuates hepatic lipid accumulation in diabetic rats and humans. These beneficial effects are possibly associated with the inhibition of lipogenic gene expression in the liver.

    Crossley, Scott A; Kyle, Kristopher; McNamara, Danielle S

    2016-12-01

    This study introduces the Tool for the Automatic Analysis of Cohesion (TAACO), a freely available text analysis tool that is easy to use, works on most operating systems (Windows, Mac, and Linux), is housed on a user's hard drive (rather than having an Internet interface), allows for the batch processing of text files, and incorporates over 150 classic and recently developed indices related to text cohesion. The study validates TAACO by investigating how its indices related to local, global, and overall text cohesion can predict expert judgments of text coherence and essay quality. The findings of this study provide predictive validation of TAACO and support the notion that expert judgments of text coherence and quality are either negatively correlated or not predicted by local and overall text cohesion indices, but are positively predicted by global indices of cohesion. Combined, these findings provide supporting evidence that coherence for expert raters is a property of global cohesion and not of local cohesion, and that expert ratings of text quality are positively related to global cohesion.

    Full Text Available The article is aimed at analyzing the development of global economy from the viewpoint of formation of ideas of its aggregation by means of the cluster analysis. It is found that during 1995-2014 in the world there were about 20 countries which GDP in total amounted to 80% of the global GDP. According to these data Japan, the USA, Germany, China, and Brazil formed a kernel of global economy. Further results of the cluster analysis have allowed to draw conclusions that during the observation period the United States and the Russian Federation remained the main centrodes of global economy. Despite the crisis of 2008, integration of global economy continued, most notably from the viewpoint of monetary indicators. The subsequent researches should be concerned with studying the economic policy directed to the internal economic development, the external relations, and formation of global economic policy, as well as to analyzing economic relations between the identified centrodes and other countries. This will help to understand the reasons of the contemporary global economic integration and to prognosticate its development in the future.

    Simiao Wan (SMW), an important multiherbal formula used in traditional Chinese medicine, is extensively used to treat rheumatoid arthritis. However, the knowledge of the bioactive components of SMW remains unclear. Thus, gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) were used to analyze the chemical constituents of volatile and nonvolatile extracts of SMW, as well as its absorbed components in rat plasma after oral SMW administration. Identification of several compounds was enabled by comparison of retention times, MS spectra, and MS/MS spectral data with the standard substance and reference materials reported in the literature. In the volatile extracts, GC-MS identified 26 compounds in vitro, three of which observed in blood by GC-MS. In the nonvolatile extracts, LC-MS identified 49 compounds in SMW; 18 compounds containing 7 prototype compounds, 5 metabolites, and 6 unknown compounds were absorbed by blood. The proposed GC-MS and LC-MS method was appropriate not only for the rapid screening and identification of multiple components of an SMW extract but also for screening its bioactive constituents in vivo. The proposed method could be a promising tool for the quality control of other Chinese herbal medicines.

  19. DNA Extraction Protocol for Biological Ingredient Analysis of Liuwei Dihuang Wan

    2014-06-01

    Full Text Available Traditional Chinese medicine (TCM preparations are widely used for healthcare and clinical practice. So far, the methods commonly used for quality evaluation of TCM preparations mainly focused on chemical ingredients. The biological ingredient analysis of TCM preparations is also important because TCM preparations usually contain both plant and animal ingredients, which often include some mis-identified herbal materials, adulterants or even some biological contaminants. For biological ingredient analysis, the efficiency of DNA extraction is an important factor which might affect the accuracy and reliability of identification. The component complexity in TCM preparations is high, and DNA might be destroyed or degraded in different degrees after a series of processing procedures. Therefore, it is necessary to establish an effective protocol for DNA extraction from TCM preparations. In this study, we chose a classical TCM preparation, Liuwei Dihuang Wan (LDW, as an example to develop a TCM-specific DNA extraction method. An optimized cetyl trimethyl ammonium bromide (CTAB method (TCM-CTAB and three commonly-used extraction kits were tested for extraction of DNA from LDW samples. Experimental results indicated that DNA with the highest purity and concentration was obtained by using TCM-CTAB. To further evaluate the different extraction methods, amplification of the second internal transcribed spacer (ITS2 and the chloroplast genome trnL intron was carried out. The results have shown that PCR amplification was successful only with template of DNA extracted by using TCM-CTAB. Moreover, we performed high-throughput 454 sequencing using DNA extracted by TCM-CTAB. Data analysis showed that 3–4 out of 6 prescribed species were detected from LDW samples, while up to 5 contaminating species were detected, suggesting TCM-CTAB method could facilitate follow-up DNA-based examination of TCM preparations.

    Currently, famous traditional Chinese medicine formulas have undergone re-evaluation and development in China. Wei-Chang-An-Wan (WCAW) as one of them has been used for treating various gastrointestinal diseases for several decades. The secondary development of WCAW is in progress so as to interpret the effective material basis or find new pharmacological activity. To evaluate the antinociceptive effect of methanol extract of WCAW (ME) as well as four fractions (P.E., EtOAc, n-BuOH, H2O) and obtain information on the correlation between the contents of the fractions and antinociceptive effect. ME was divided into four parts extracted by petroleum ether, ethyl acetate and n-butanol. Antinociceptive activity was evaluated by three models of acetic acid-induced writhing, formalin and hot-plate test in mice after repetitive administration of ME at 200, 400 or 800 mg/kg, P.E. 132 mg/kg, EtOAc 106 mg/kg, n-BuOH 176 mg/kg and H2O 176 mg/kg for six days. The chemical compounds were analyzed by HPLC-ESI-MS. ME at 800 mg/kg inhibited acid-induced writhing by 84.69%, and reduced the licking time of second phase in formalin test by 53.23%. The inhibition rates in acid-induced writhing of P.E., EtOAc, n-BuOH and H2O were 27.79, 33.85, 38.97 and 37.69%, respectively, and in formalin test about 50%. They had no effect on the hot-plate test. HPLC-ESI-MS analysis showed that 68 chemical compounds were detected and 41 compounds were identified from ME. The results obtained herein indicate that WCAW possesses the antinociceptive activity that provides a new aspect in clinical application.

    In this work we present the architectural and performance studies concerning a prototype of a distributed Tier2 infrastructure for HEP, instantiated between the two Italian sites of INFN-Romal and INFN-Napoli. The network infrastructure is based on a Layer-2 geographical link, provided by the Italian NREN (GARR), directly connecting the two remote LANs of the named sites. By exploiting the possibilities offered by the new distributed file systems, a shared storage area with synchronous copy has been set up. The computing infrastructure, based on an OpenStack facility, is using a set of distributed Hypervisors installed in both sites. The main parameter to be taken into account when managing two remote sites with a single framework is the effect of the latency, due to the distance and the end-to-end service overhead. In order to understand the capabilities and limits of our setup, the impact of latency has been investigated by means of a set of stress tests, including data I/O throughput, metadata access performance evaluation and network occupancy, during the life cycle of a Virtual Machine. A set of resilience tests has also been performed, in order to verify the stability of the system on the event of hardware or software faults. The results of this work show that the reliability and robustness of the chosen architecture are effective enough to build a production system and to provide common services. This prototype can also be extended to multiple sites with small changes of the network topology, thus creating a National Network of Cloud-based distributed services, in HA over WAN.

    In the oncology population where malnutrition prevalence is high, more descriptive screening tools can provide further information to assist triaging and capture acute change. The Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF) is a component of a nutritional assessment tool which could be used for descriptive nutrition screening. The purpose of this study was to conduct a secondary analysis of nutrition screening and assessment data to identify the most relevant information contributing to the PG-SGA SF to identify malnutrition risk with high sensitivity and specificity. This was an observational, cross-sectional study of 300 consecutive adult patients receiving ambulatory anti-cancer treatment at an Australian tertiary hospital. Anthropometric and patient descriptive data were collected. The scored PG-SGA generated a score for nutritional risk (PG-SGA SF) and a global rating for nutrition status. Receiver operating characteristic curves (ROC) were generated to determine optimal cut-off scores for combinations of the PG-SGA SF boxes with the greatest sensitivity and specificity for predicting malnutrition according to scored PG-SGA global rating. The additive scores of boxes 1-3 had the highest sensitivity (90.2 %) while maintaining satisfactory specificity (67.5 %) and demonstrating high diagnostic value (AUC = 0.85, 95 % CI = 0.81-0.89). The inclusion of box 4 (PG-SGA SF) did not add further value as a screening tool (AUC = 0.85, 95 % CI = 0.80-0.89; sensitivity 80.4 %; specificity 72.3 %). The validity of the PG-SGA SF in chemotherapy outpatients was confirmed. The present study however demonstrated that the functional capacity question (box 4) does not improve the overall discriminatory value of the PG-SGA SF.

    Full Text Available Many new websites and online tools have come into existence to support scholarly communication in all phases of the research workflow. To what extent researchers are using these and more traditional tools has been largely unknown. This 2015-2016 survey aimed to fill that gap. Its results may help decision making by stakeholders supporting researchers and may also help researchers wishing to reflect on their own online workflows. In addition, information on tools usage can inform studies of changing research workflows. The online survey employed an open, non-probability sample. A largely self-selected group of 20663 researchers, librarians, editors, publishers and other groups involved in research took the survey, which was available in seven languages. The survey was open from May 10, 2015 to February 10, 2016. It captured information on tool usage for 17 research activities, stance towards open access and open science, and expectations of the most important development in scholarly communication. Respondents’ demographics included research roles, country of affiliation, research discipline and year of first publication.

  11. Technical Knowledge, Cultural Practices and Social Boundaries: Wan-Nan Scholars and the Recasting of Jesuit Astronomy, 1600-1800

    Science.gov (United States)

    Chu, Ping-Yi.

    Taking four Wan-nan Confucian scholars--Yang Kuang -hsien, Mei Wen-ting, Chiang Yung and Tai Chen--as examples, this dissertation studies how an immigrant Jesuit scientific community built and defended itself in a specialized institutional niche located at the Ch'ing court and how a defeated Chinese scientific tradition successfully survived by occupying a broader cultural space, with the Manchu emperor in between. Special attention is paid to how these four Confucian scholars constructed social boundaries between the Chinese and the Westerners in their astronomical discourses and how they domesticated Western astronomy in order to fit the Chinese cultural conditions situated in the power structure built by the Manchus. This inquiry begins with a brief introduction of Wan-nan and the Wan-nan school. I then discuss how the Jesuits legitimated their knowledge during the Ming -Ch'ing transition, and how Jesuit astronomy was situated within the power nexus between the Confucian literati and the emperors. The next chapter focuses on Yang Kuang-hsien and his challenges to the Jesuits. I examine his strategies and the power structure in which Yang carried out his challenge to the Jesuits. The fourth and fifth chapters investigate how Mei Wen-ting restructured the relationship between Confucianism and astronomy. The former chapter focuses on Mei's social networking and his ambivalence towards the Ming and Ch'ing dynasties, on the one hand, and towards Chinese and Western learning on the other. The latter chapter deals with how Mei Wen-ting recast Chinese astronomical tradition and Confucianism. In the sixth chapter, I will compare the fame of Chiang Yung and Tai Chen in order to demonstrate how astronomy was practiced in evidential studies after Mei Wen-ting, and how evidential studies itself conveyed an ideological construction of the other.

    Global land acquisitions, often dubbed ‘land grabbing’ are increasingly becoming drivers of land change. We use the tools of network science to describe the connectivity of the global acquisition system. We find that 126 countries participate in this form of global land trade. Importers are concentrated in the Global North, the emerging economies of Asia, and the Middle East, while exporters are confined to the Global South and Eastern Europe. A small handful of countries account for the majority of land acquisitions (particularly China, the UK, and the US), the cumulative distribution of which is best described by a power law. We also find that countries with many land trading partners play a disproportionately central role in providing connectivity across the network with the shortest trading path between any two countries traversing either China, the US, or the UK over a third of the time. The land acquisition network is characterized by very few trading cliques and therefore characterized by a low degree of preferential trading or regionalization. We also show that countries with many export partners trade land with countries with few import partners, and vice versa, meaning that less developed countries have a large array of export partnerships with developed countries, but very few import partnerships (dissassortative relationship). Finally, we find that the structure of the network is potentially prone to propagating crises (e.g., if importing countries become dependent on crops exported from their land trading partners). This network analysis approach can be used to quantitatively analyze and understand telecoupled systems as well as to anticipate and diagnose the potential effects of telecoupling.

    Computational models play an increasingly important role in the assessment and control of public health crises, as demonstrated during the 2009 H1N1 influenza pandemic. Much research has been done in recent years in the development of sophisticated data-driven models for realistic computer-based simulations of infectious disease spreading. However, only a few computational tools are presently available for assessing scenarios, predicting epidemic evolutions, and managing health emergencies that can benefit a broad audience of users including policy makers and health institutions. We present "GLEaMviz", a publicly available software system that simulates the spread of emerging human-to-human infectious diseases across the world. The GLEaMviz tool comprises three components: the client application, the proxy middleware, and the simulation engine. The latter two components constitute the GLEaMviz server. The simulation engine leverages on the Global Epidemic and Mobility (GLEaM) framework, a stochastic computational scheme that integrates worldwide high-resolution demographic and mobility data to simulate disease spread on the global scale. The GLEaMviz design aims at maximizing flexibility in defining the disease compartmental model and configuring the simulation scenario; it allows the user to set a variety of parameters including: compartment-specific features, transition values, and environmental effects. The output is a dynamic map and a corresponding set of charts that quantitatively describe the geo-temporal evolution of the disease. The software is designed as a client-server system. The multi-platform client, which can be installed on the user's local machine, is used to set up simulations that will be executed on the server, thus avoiding specific requirements for large computational capabilities on the user side.

    Full Text Available The SGA is a clinical tool used to assess protein energy wasting. Although well validated, it is still not widely incorporated into clinical practice. A barrier to use may be the physical assessment section. Therefore, the purpose of this project was to develop a free and effective tool to train clinicians on performing the SGA. Second Life (SL is a free virtual reality program accessed through the internet using human-like “avatars.” A museum environment was created with panels presenting SGA background information through text, images, and videos of SGA being performed. Users are able to navigate the information by logging onto a provided avatar. After the initial panels, this avatar is able to interact with avatar bots and perform animations which mimic each body assessment within the SGA. Two trial periods were conducted to assess the efficacy of this training tool. The alpha trial consisted of 3 hospital dietitians and 3 nutrition students. These subjects came to the investigators’ facility to test the program. Subjective responses were collected and used to improve the training tool. Feedback was positive regarding the information, delivery, and direction of the project; however, they did complain of difficulty with controlling the avatar. The beta trial consists of users accessing the module remotely. These users include academic and clinical dietitians. Responses are being collected via 5 surveys covering each portion of the module. While 16 dietitians responded to the beta trial, only 4 have completed the training. Current survey responses state: the use of SL is easy and enjoyable; all SGA information was clear and in a desirable format; tactile comparison objects were beneficial for understanding; the in depth description of each assessment is beneficial; the animations that the avatars perform on the bots needs improvement; a patient avatar on which users could perform the full SGA is desirable; the use of SL in the learning

    Full Text Available Zuo Gui Wan (ZGW and You Gui Wan (YGW are two classic formulas used in clinical treatment of infertility in traditional Chinese medicine (TCM. However, the actions of the formulas remain to be proven at the cellular and molecular levels. In this study, we investigate whether the two formulas have any effect on germ cell formation and differentiation by culturing rat medicated serums containing YGW or ZGW with stem cells derived from human first trimester umbilical cord. Our results showed that while the normal rat serums had no significant effects, the rat medicated serums had significant effects on the differentiation of the stem cells into oocyte-like cells (OLCs based on (1 cell morphological changes that resembled purative cumulus-oocyte complexes (COCs; (2 expressions of specific markers that were indicative of germ cell formation and oocyte development; and (3 estradiol production by the COC-like cells. Furthermore, ZGW medicated serums exhibited more obvious effects on specific gene expressions of germ cells, whereas YGW medicated serums showed stronger effects on estradiol production. Accordingly, our study provides evidence demonstrating for the first time that one of molecular and cellular actions of YGW or ZGW in treating human reproductive dysfunctions may be through an enhancement of neooogenesis.

    Globalization is often referred to as external to education - a state of affair facing the modern curriculum with numerous challenges. In this paper it is examined as internal to curriculum; analysed as a problematization in a Foucaultian sense. That is, as a complex of attentions, worries, ways...... of reasoning, producing curricular variables. The analysis is made through an example of early childhood curriculum in Danish Pre-school, and the way the curricular variable of the pre-school child comes into being through globalization as a problematization, carried forth by the comparative practices of PISA...

    2011-01-01

    Hemoglobinopathies are the most common global monogenic disorders with significant mortality and morbidity of the survivors. This is due to poor understanding of the disease(s) by health care professionals and also lack of resources. We have designed a Master's degree in hemoglobinopathies course, the first of its kind, using cutting-edge lively state-of the-art media-based technology, to attain excellence in teaching and learning. The modular program is delivered by 100% virtual learning (VLE) tools. The lectures, given by international experts, are blended with interactive quizzes and assessment tools to make the program engaging. Other activities include video-based tutorials, walk-in surgeries, journal clubs and other web-based activities. We have currently received 40 intakes and the program is running successfully with excellent student feedback using quality control framework of the University College London (UCL), London, UK. In conclusion, we have shown the feasibility of VLE for knowledge and skill transfer to global healthcare professionals for a monogenic disorder.

    To evaluate robotic dry laboratory (dry lab) exercises in terms of their face, content, construct and concurrent validities. To evaluate the applicability of the Global Evaluative Assessment of Robotic Skills (GEARS) tool to assess dry lab performance. Participants were prospectively categorized into two groups: robotic novice (no cases as primary surgeon) and robotic expert (≥30 cases). Participants completed three virtual reality (VR) exercises using the da Vinci Skills Simulator (Intuitive Surgical, Sunnyvale, CA, USA), as well as corresponding dry lab versions of each exercise (Mimic Technologies, Seattle, WA, USA) on the da Vinci Surgical System. Simulator performance was assessed by metrics measured on the simulator. Dry lab performance was blindly video-evaluated by expert review using the six-metric GEARS tool. Participants completed a post-study questionnaire (to evaluate face and content validity). A Wilcoxon non-parametric test was used to compare performance between groups (construct validity) and Spearman's correlation coefficient was used to assess simulation to dry lab performance (concurrent validity). The mean number of robotic cases experienced for novices was 0 and for experts the mean (range) was 200 (30-2000) cases. Expert surgeons found the dry lab exercises both 'realistic' (median [range] score 8 [4-10] out of 10) and 'very useful' for training of residents (median [range] score 9 [5-10] out of 10). Overall, expert surgeons completed all dry lab tasks more efficiently (P concurrent validity with the corresponding VR tasks. Until now, the assessment of dry lab exercises has been limited to basic metrics (i.e. time to completion and error avoidance). For the first time, we have shown it is feasibile to apply a global assessment tool (GEARS) to dry lab training. © 2013 The Authors. BJU International © 2013 BJU International.

    The paper will report on the progress of an ongoing EU project called GRACE - Grid Search and Categorization Engine (http://www.grace-ist.org). The project participants are CERN, Sheffield Hallam University, Stockholm University, Stuttgart University, GL 2006 and Telecom Italia. The project started in 2002 and will finish in 2005, resulting in a Grid based search engine that will search across a variety of content sources including a number of electronic thesis and dissertation repositories. The Open Archives Initiative (OAI) is expanding and is clearly an interesting movement for a community advocating open access to ETD. However, the OAI approach alone may not be sufficiently scalable to achieve a truly global ETD Digital Library. Many universities simply offer their collections to the world via their local web services without being part of any federated system for archiving and even those dissertations that are provided with OAI compliant metadata will not necessarily be picked up by a centralized OAI Ser...

    Wikipedia is an encyclopedia collaboratively edited by volunteers from around the world built on the Web since 2003. Today is the sixth most visited site on the Internet, making it the biggest hit of participatory democracy in the field of information dissemination. The English edition, with more than 3 million items, has become an indispensable part of the Internet and the largest and most popular reference work. In this context, it could be argued that Wikipedia is a valuable tool for the general knowledge of the nutritional sciences terminology. At the same time, it does not only facilitate access to knowledge but also can generate it. It also permits to socialize these spaces for collaboration and development, contributing therefore to disclose science to the society. Consequently, in this article we present and discuss the main features of Wikipedia, emphasizing above all its role in food science and nutrition.

  2. The application of systems thinking concepts, methods, and tools to global health practices: An analysis of case studies.

    2017-11-20

    This review of systems thinking (ST) case studies seeks to compile and analyse cases from ST literature and provide practitioners with a reference for ST in health practice. Particular attention was given to (1) reviewing the frequency and use of key ST terms, methods, and tools in the context of health, and (2) extracting and analysing longitudinal themes across cases. A systematic search of databases was conducted, and a total of 36 case studies were identified. A combination of integrative and inductive qualitative approaches to analysis was used. Most cases identified took place in high-income countries and applied ST retrospectively. The most commonly used ST terms were agent/stakeholder/actor (n = 29), interdependent/interconnected (n = 28), emergence (n = 26), and adaptability/adaptation (n = 26). Common ST methods and tools were largely underutilized. Social network analysis was the most commonly used method (n = 4), and innovation or change management history was the most frequently used tool (n = 11). Four overarching themes were identified; the importance of the interdependent and interconnected nature of a health system, characteristics of leaders in a complex adaptive system, the benefits of using ST, and barriers to implementing ST. This review revealed that while much has been written about the potential benefits of applying ST to health, it has yet to completely transition from theory to practice. There is however evidence of the practical use of an ST lens as well as specific methods and tools. With clear examples of ST applications, the global health community will be better equipped to understand and address key health challenges. © 2017 John Wiley & Sons, Ltd.

  3. A streamlined DNA tool for global identification of heavily exploited coastal shark species (genus Rhizoprionodon.

    Danillo Pinhal

    Full Text Available Obtaining accurate species-specific landings data is an essential step toward achieving sustainable shark fisheries. Globally distributed sharpnose sharks (genus Rhizoprionodon exhibit life-history characteristics (rapid growth, early maturity, annual reproduction that suggests that they could be fished in a sustainable manner assuming an investment in monitoring, assessment and careful management. However, obtaining species-specific landings data for sharpnose sharks is problematic because they are morphologically very similar to one another. Moreover, sharpnose sharks may also be confused with other small sharks (either small species or juveniles of large species once they are processed (i.e., the head and fins are removed. Here we present a highly streamlined molecular genetics approach based on seven species-specific PCR primers in a multiplex format that can simultaneously discriminate body parts from the seven described sharpnose shark species commonly occurring in coastal fisheries worldwide. The species-specific primers are based on nucleotide sequence differences among species in the nuclear ribosomal internal transcribed spacer 2 locus (ITS2. This approach also distinguishes sharpnose sharks from a wide range of other sharks (52 species and can therefore assist in the regulation of coastal shark fisheries around the world.

    Full Text Available It has been defined that knowledge society emerges at the end of the twentieth century as the socio-economic structure characteristic for developed societies in which unlike in industrial societies, the dominant sector of economy is services and the largest social group is the “men of knowledge”. It has been indicated that the development of the knowledge society is considered in connection with scientific and technological development and the expansion of new technologies as they determined is that we live in a globalized world, connected by a dense network of connections and intensive contacts both between the individuals and the authorities at local, regional, national and transnational or institutions level or between the institutions of various types, among which, of course, there are also educational institutions, including universities. It has been concluded that the accentuated thought should be read as a contemporary call for the implementation of the classic academic ideas in the conditions of the use of new technologies. Paraphrasing a metaphor of J. Morbitzer, modern university institutions should become intellectual arcs that will save humanity from the information deluge, the flood of endless, murky waves to safely bring it to the port of the society in which knowledge will be a resource for creative and innovative activities. A very important task is in the situation of current unprecedented acceleration of technical and technological progress not to lose the deep humanistic character of the educational process in which the modern technology should well serve a man and not contribute to its enslavement.

    Full Text Available International investment is one of the key drivers of economic growth in today’s world economy. Thus, creating favourable investment conditions is imperative for any state willing to maintain its competitiveness in attracting international investment capital required for sustainable economic growth. In this regard, the harmonization of investment and regulatory environments is one of the pressing issues facing many countries around the world. Addressing this issue is a collective task to be undertaken by leading economies, international organizations and informal global governance institutions, such as the Group of 20 (G20 or BRICS group of Brazil, Russia, India, China and South Africa. The contribution of the Organisation for Economic Co-operation and Development (OECD to harmonizing international investment regimes is significant and includes such documents as the OECD Declaration on International Investment and Multinational Enterprises, the Code of Liberalisation of Capital Movements, the Code of Liberalisation of Current Invisible Operations, G20/OECD High-Level Principles of Long-Term Investment Financing, and the Policy Framework for Investment (PFI. The PFI has become the most comprehensive and exhaustive compendium of investment policy best practices. This article analyzes the evolution of the PFI and the negotiation processes behind it to compare its content with analogous international documents dealing with investment policy and regulation across all 12 issue areas covered by the PFI, as well as to assess the international business community’s corresponding positions and contributions. It also addresses the OECD-G20 cooperation in formulating the future agenda for investment policy among the leading economies. The selected approach allows for a determination of the PFI’s role in shaping the potential set of universal investment policy principles and concrete rules.

    The Colima Volcano is currently the most active Mexican volcano. After the 1913 plinian activity, the volcano presented scattered eruptive phases that lasted few years each, but since 1991 its activity became more persistent, with vulcanian eruptions, and extrusion of lava flows and domes. During the last 15 years the volcano suffered several eruptive episodes, as in 1991, 1994, 1998-1999, 2001-2003, 2004 and 2005, with the emplacement of pyroclastic flows. During rain seasons lahars are frequently affecting several infrastructures such as bridges and electric towers. Researchers from different institutions are currently working on several key aspects of the volcano, as remote sensing, field data of old and recent volcaniclastic deposits, structural framework, monitoring (rainfall data and visual observation of lahars), and laboratory experiment (analogue models and numerical simulations). Each investigation is focused on specific processes, but it is fundamental to visualize the global status of the volcano in order to understand its behavior and to mitigate future hazards. The Colima Volcano Database represents an initiative aimed to collect, on a systematic basis, the complete set of data obtained so far on the volcano, and to continuously update the database with new data. All the information is compiled from published works and updated frequently. All maps (such as the geological map of the volcano and the hazard zonations compiled from previous works) and point data (such as stratigraphic sections, sedimentology and diagrams of rainfall intensities) can be viewed with Google Earth and is really straightforward to be access by the scientific community and the general public. In this format everyone with Internet access can view the information and zoom to the scale they wish. The WebGIS is hosted on the Computational Geodynamics Laboratory web server and it is based entirely on Open Source software. The website can be visited at: http://www.geociencias.unam.mx/colima.

    Music can be a powerful device for raising awareness about environmental issues. Following the trend, we are organizing a project to specifically address climatic and environmental emergencies. To this aim, we use the transformation of geophysical data into musical notes, according to the procedure (EMusic) defined by Menghini and Pontani (2016). We claim that it is possible to compose musical tracks describing faithfully the geological and environmental setting of various sites, which we choose by considering five main topics: 1) Pollution of aquifers; 2) Seawater intrusion along the coastlines; 3) Seismic risk; 4) Drought; 5) Permafrost melting; The TDEM method (Time Domain Electromagnetics) shows an excellent diagnostic feature for each of these environmental emergencies. It is not surprising that the technical-scientific community widely acquire TDEM data since many years as the variations of the recorded signal (voltage) duly reflect the modifications induced on the Earth system. Through the sonification process, we can associate well-defined musical "footprints" to these geophysical variations. Then, we have an extraordinary didactic-popular tool that we can use to communicate and sensitize people and students of every age and grade about the impact of climatic-environmental changes. In this occasion, we present, among others, the example of the musical effect of seawater intrusion that is well marked by the progressive increase of the pitches when approaching the coastline. In many cases, the relationship between geophysical response and high environmental risk is straight: for instance, pollutants, like leachate or polluted groundwater, can produce high voltage responses and/or similar high voltage signals can be produced by soils affected by permafrost melting. Nevertheless, there are situations in which the diagnostic feature of TDEM is fair, however, even if the data interpretation is less immediate, so that it requires an accurate processing and

    Volcanic plumes and drifting ash clouds pose a risk to flight operations somewhere across the globe every day. Airborne ash plumes pose a significant hazard to aircraft and timely and accurate forecasts greatly help mitigate the risk of an encounter. The world's nine (9) Volcanic Ash Advisory Centers (VAACs) provide products and services to address the volcanic ash hazard to aviation. These nine centers are operated by the meteorological authority within the state in which they are located. Each VAAC has its unique set of tools and procedures on how the data will be captured, displayed, analyzed and turned into a suite of products. The end products (e.g. Volcanic Ash Advisories (VAA) and Volcanic Ash Graphic (VAG)) are standardized through the International Civil Aviation Organization's International Airways Volcano Watch Operations Group (ICAO IAVWOPSG). Improvements in methods of collaboration between the VAACs are needed to allow for a seamless global harmonization of volcanic ash products. A geospatially enabled tool would allow for a common operating platform, data sharing, and situational awareness. The North American VAACs have been testing a capability to provide this environment to make forecast collaboration simple across the globe. This presentation highlights work that has been done to demonstrate this capability.

    Countries around the world are currently aiming to improve patient safety by means of the Institute for Healthcare Improvement global trigger tool (GTT), which is considered a valid tool for evaluating and measuring patient safety within organisations. So far, only few data on the measurement properties and utility of the GTT have been published. To determine and evaluate the effect of interrater variation between review teams on the standard outcome measures of the GTT and to assess and quantify measurement error of the GTT. Retrospective chart reviews were conducted on identical charts by two independent review teams in 2010 at a department of oncology in a university hospital. Standard GTT outcome measurements were obtained and compared between teams using statistical process control (SPC) charts. A Bland-Altman plot assessed measurement error and limits of agreement. Only 31% of adverse events (AE) were identified by both teams, and further differences in categorisation of identical events was found. Moderate interrater agreement (κ=0.45) between teams gave rise to different conclusions on the patient safety process when monitoring using SPC charts. The Bland-Altman plot suggests little systematic error but large random error. Review teams may identify different AE and reach different conclusions on the safety process when using the GTT on identical charts. Tracking true change in the safety level is difficult due to measurement error of the GTT. The results do not encourage further use of the GTT until additional evaluation studies on the measurement properties of the GTT have been conducted.

    Center for Hydrometeorology and Remote Sensing (CHRS), University of California, Irvine has recently developed the CHRS RainSphere (hosted at http://rainsphere.eng.uci.edu) for scientific studies and applications using the Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks - Climate Data Record (PERSIANN-CDR, Ashouri et al. 2015). PERSIANN-CDR is a long-term (33+ years) high-resolution (daily, 0.25 degree) global satellite precipitation dataset which is useful for climatological studies and water resources applications. CHRS RainSphere has functionalities allowing users to visualize and query spatiotemporal statistics of global daily satellite precipitation for the past three decades. With a couple of mouse-clicks, users can easily obtain a report of time series, spatial plots, and basic trend analysis of rainfall for various spatial domains of interest such as location, watershed, basin, political division and country for yearly, monthly, monthly by year or daily. Mann-Kendall test is implemented on CHRS RainSphere for statistically investigating whether there is a significant increasing/decreasing rainfall trend at a location or over a specific spatial domain. CHRS RainSphere has a range of capabilities and should appeal to a broad spectrum of users including climate scientists, water resources managers and planners, and engineers. CHRS RainSphere can also be a useful educational tool for the general public to investigate climate change and variability. The video tutorial on CHRS RainSphere is available at https://www.youtube.com/watch?v=eI2-f88iGlY&feature=youtu.be. A demonstration of CHRS RainSphere will be included in the presentation.

    2006-05-01

    The Global Earth Observation System of Systems (GEOSS) framework identifies the benefits of systematically and scientifically networking the capacity of organizations and systems into solutions that benefit nine societal benefit areas. The U.S. Integrated Earth Observation System (IEOS), the U.S. contribution to the GEOSS, focuses on near-term, mid-term, and long-term opportunities to establish integrated system solutions based on capacities and capabilities of member agencies and affiliations. Scientists at NASA, NOAA, DOE, NSF and other U.S. agencies are evolving the predictive capacity of models of Earth processes based on space-based, airborne and surface-based instruments and their measurements. NASA research activities include advancing the power and accessibility of computational resources (i.e. Project Columbia) to enable robust science data analysis, modeling, and assimilation techniques to rapidly advance. The integration of the resulting observations and predictions into decision support tools require characterization of the accuracies of a range of input measurements includes temperature and humidity profiles, wind speed, ocean height, sea surface temperature, and atmospheric constituents that are measured globally by U.S. deployed spacecraft. These measurements are stored in many data formats on many different information systems with widely varying accessibility and have processes whose documentation ranges from extremely detailed to very minimal. Integrated and interdisciplinary modeling (enabled by the Earth System Model Framework) enable the types of ensemble analysis that are useful for decision processes associated with energy management, public health risk assessments, and optimizing transportation safety and efficiency. Interdisciplinary approaches challenge systems integrators (both scientists and engineers) to expand beyond the traditional boundaries of particular disciplines to develop, verify and validate, and ultimately benchmark the

    The use of social media in health education has witnessed a revolution within the past decade. Students have already adopted social media informally to share information and supplement their lecture-based learning. Although studies show comparable efficacy and improved engagement when social media is used as a teaching tool, broad-based adoption has been slow and the data on barriers to uptake have not been well documented. The objective of this study was to assess attitudes of health educators toward social media use in education, examine differences between faculty members who do and do not use social media in teaching practice, and determine contributing factors for an increase in the uptake of social media. A cross-sectional Web-based survey was disseminated to the faculty of health professional education departments at 8 global institutions. Respondents were categorized based on the frequency of social media use in teaching as "users" and "nonusers." Users sometimes, often, or always used social media, whereas nonusers never or rarely used social media. A total of 270 health educators (52.9%, n=143 users and 47.0%, n=127 nonusers) were included in the survey. Users and nonusers demonstrated significant differences on perceived barriers and potential benefits to the use of social media. Users were more motivated by learner satisfaction and deterred by lack of technology compatibility, whereas nonusers reported the need for departmental and skill development support. Both shared concerns of professionalism and lack of evidence showing enhanced learning. The majority of educators are open-minded to incorporating social media into their teaching practice. However, both users and nonusers have unique perceived challenges and needs, and engaging them to adapt social media into their educational practice will require previously unreported approaches. Identification of these differences and areas of overlap presents opportunities to determine a strategy to increase

    The wide area networks for data transmission are submitting to evolution process by technological progress and unrelated process to the network. The evolution process can be originated by the bottom up integration of different networks that were born to solve specific problems (i.e.: scientific calculations and business administration). The ENET WAN of ENEA had been submitted to the same evolution progress. In this thesis the author analyze all the problems about WAN with emphasis in ENET WAN. The purpose of this research is the analysis of the present situation in particularly links, efficiency, expenses and throughput. The goal is to suggest alternative solutions to optimized the network and to amplify the throughput by new technology. The research suggests in particularly two new wide area networks: ENET{sub C}-LAN95 e ENET{sub S}ERV96. The first one is a mix interconnection solution, that is basis on the public network C-LAN, with the transportation protocol Frame Relay, and on the private links Numerical Direct Channels (CDN). The second one is also a mix interconnection solution, but it is based on two new network services that are supplied by two new public networks just introduce in Italian telecommunications market since `96. Frame Relay and ATM are the transportation protocol employed.

    Classical Chinese pharmacopeias describe numerous excellent herbal formulations, and each prescription is an outstanding pool of effective compounds for drug discovery. Clarifying the bioactivity of the combined mechanisms of the ingredients in complex traditional Chinese medicine formulas is challenging. A classical formula known as Qingfei Xiaoyan Wan, used clinically as a treatment for prevalent chronic lung disease, was investigated in this work. A mutually enhanced bioactivity-guided ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS) characterization system was proposed, coupled with a dual-luciferase reporter assay for β2AR-agonist cofactor screening. Arctiin, arctigenin, descurainoside and descurainolide B, four lignin compounds that showed synergistic bronchodilation effects with ephedrine, were revealed. The synergistic mechanism of arctigenin with the β2ARagonist involved with the reduction of free Ca2+ was clarified by a dual-luciferase reporter assay for intracellular calcium and the Ca2+ indicator fluo-4/AM to monitor changes in the fluorescence. The relaxant and contractile responses of airway smooth muscle are regulated by crosstalk between the intracellular cAMP and calcium signaling pathways. Our data indicated the non-selective βAR agonist ephedrine as the principal bronchodilator of the formula, whereas the lignin ingredients served as adjuvant ingredients. A greater understanding of the mechanisms governing the control of these pathways, based on conventional wisdom, could lead to the identification of novel therapeutic targets or new agents for the treatment of asthma and COPD.

    Full Text Available A traditional Chinese medicine (TCM formula, Zuo Jin Wan (ZJW, has been found as an anticancer drug in human cancer. In this study, we investigated the synergistic effect of ZJW extracts on DDP-induced apoptosis in human gastric cancer SGC-7901/DDP cells. Our results demonstrated that ZJW extracts could increase the sensitivity of SGC-7901/DDP cells to DDP by increasing the concentration of DDP in cytoplasm and enhance the proapoptosis of DDP by upregulating the JNK and Bax expression, downregulating the Bcl-2 expression, increasing the accumulation of Cytochrome C in cytoplasm, and promoting the activities of caspase-3 and caspase-9. In vivo, ZJW extracts enhanced the inhibiting effect of DDP on tumor growth in SGC-7901/DDP xenograft model and upregulated the expression of p-JNK and Bax but downregulated the Bcl-2 expression in xenograft tumors. In conclusion, in vitro and in vivo, ZJW extracts could enhance the proapoptotic effect of DDP by promoting the activation of JNK and the expression of Bcl-2, inhibiting the Bax expression, followed by increasing the release of Cytochrome C from mitochondria to cytoplasm, and finally activating the caspase cade reaction. Our results implied that ZJW might serve as a synergistic drug with chemotherapeutic drugs DDP in the treatment of gastric cancer.

    We evaluated the feasibility of fingerprint-scanners in combination with smart cards for personal identification and transmission of encrypted TCP/IP-data-packages via satellite between the university-hospital of Innsbruck and the rural hospital of Reutte. The aim of our study was the proof of the userfriendliness of the SkymedTM technology for security purpose in teleradiology. We examined the time of the personal identification process, the time for the necessary training and the personal satisfaction. The images were sent from the local PACS in Reutte via a Data-Encryption-and-Transmission- Box via satellite from Reutte to Innsbruck. We used an asymmetric bandwidth of 512 kbit/s from Reutte to Innsbruck and 128 kbit/s in the opposite direction. Window NT 4.0- operating PCs were used for the electronical patient record, the medical inquiry of the referring physician and the final report of the radiologist. The images were reported on an UNIX-PACS viewing station. After identification through fingerprint-scanners in combination with the smart card the radiologist was able to open the electronic patient record (EPR) from Reutte and sign with his digital signature his confirmed final report before it was send back to Reutte. The used security technology enables encrypted communication over a WAN, which fulfill data-protection.

    The blending end-point determination of Angong Niuhuang Wan (AGNH) is a key technology problem. The control strategy based on quality by design (QbD) concept proposes a whole blending end-point determination method, and provides a methodology for blending the Chinese materia medica containing mineral substances. Based on QbD concept, the laser induced breakdown spectroscopy (LIBS) was used to assess the cinnabar, realgar and pearl powder blending of AGNH in a pilot-scale experiment, especially the whole blending end-point in this study. The blending variability of three mineral medicines including cinnabar, realgar and pearl powder, was measured by moving window relative standard deviation (MWRSD) based on LIBS. The time profiles of realgar and pearl powder did not produce consistent results completely, but all of them reached even blending at the last blending stage, so that the whole proposal blending end point was determined. LIBS is a promising Process Analytical Technology (PAT) for process control. Unlike other elemental determination technologies such ICP-OES, LIBS does not need an elaborate digestion procedure, which is a promising and rapid technique to understand the blending process of Chinese materia medica (CMM) containing cinnabar, realgar and other mineral traditional Chinese medicine. This study proposed a novel method for the research of large varieties of traditional Chinese medicines.. Copyright© by the Chinese Pharmaceutical Association.

  2. The absence of fan activism in the queer fandom of Ho Denise Wan See (HOCC in Hong Kong

    Full Text Available The queer fandom of female Hong Kong pop singer Ho Denise Wan See (HOCC from 2009 to mid-2011 is dealt with through the qualitative methodology of in-depth interviews and media ethnography. HOCC, an idiosyncratic cultural producer who dabbles in the politics of ambiguity, creates texts that invite queer interpretations from fans and from queer activists in Hong Kong. Via analyses informed by both queer studies and audience studies, the various creative practices of fans in reshaping their sexual identities via popular culture are explored. These practices are highly political and empowering to a queer audience. However, the intensive rewriting of meanings as queer symbolic creativity and tactics in cultural politics fail to transform into formal institutional politics and more confrontational queer activism. This is so for several reasons. Internally, the hierarchical structure of fan organization, fan proximity to the culture industry, and the top-down encouragement of social charity as the only channel of activism have all reduced the possibility of transforming fans' queer sensibilities into institutional queer politics. Furthermore, Hong Kong, under the influence of three major discourses that seek to discipline and regulate sexualities—traditional Chinese ethics, the British colonial legacy, and the postcolonial revival of rightist Christianity—has a long social history of heterosexist discrimination and a preference for normalizing when striving for queer citizenship. This empirical study examines relations between cultural specificity and fan agency in a non-Western context.

    Traditional Chinese medicine (TCM) formula has been used for over 1000 years and most of them contain complicate chemical constituents. Chromatographic fingerprinting has been widely accepted as a crucial method for qualitative and quantitative analyses for TCM. Zhi Zhu Wan (ZZW), a classical Chinese medical formula, has been commonly used for the treatment of gastrointestinal disease, which pose a serious challenge to its quality control. In this work, a sensitive and reliable method of high-performance liquid chromatography coupled with photodiode array detector (HPLC-PDA) was developed to control the quality of ZZW for chemical fingerprint analysis and quantitative analysis of four major bioactive constituents, including hesperidin, naringin, neohesperidin, and atractylenolide I. The chromatographic separation was performed on a Waters Symmetry C18 column (4.6 mm × 250 mm, 5 μm particle size), with an aqueous 0.095% phosphate acid and acetonitrile mobile phase gradient. Optimization of other experimental conditions was validated with satisfactory accuracy, precision, repeatability, and recovery. In quantitative analysis, the four components showed good regression (R > 0.9994) within test ranges, and the recovery method ranged from 99.32% to 100.630%. HPLC fingerprints of the ZZW samples were compared by performing similarity analysis. The results indicated that the newly developed HPLC-PDA fingerprint method would be suitable for quality control of ZZW.

    The GIOD (Globally Interconnected Object Databases) Project, a joint effort between Caltech and CERN, funded by Hewlett Packard Corporation, has investigated the use of WAN-distributed Object Databases and Mass Storage systems for LHC data. A prototype small-scale LHC data analysis center has been constructed using computing resources at Caltechs Centre for Advanced Computing Research (CACR). These resources include a 256 CPU HP Exemplar of ˜4600 SPECfp95, a 600 TByte High Performance Storage System (HPSS), and local/wide area links based on OC3 ATM. Using the Exemplar, a large number of fully simulated CMS events were produced, and used to populate an object database with a complete schema for raw, reconstructed and analysis objects. The reconstruction software used for this task was based on early codes developed in preparation for the current CMS reconstruction program, ORCA. Simple analysis software was then developed in Java, and integrated with SLACs Java Analysis Studio tool. An event viewer was constructed with the Java 3D API. Using this suite of software, tests were made in collaboration with researchers at FNAL and SDSC, that focused on distributed access to the database by numerous clients, and measurements of peak bandwidths were made and interpreted. In this paper, some significant findings from the GIOD Project are presented, such as the achievement of the CMS experiment's 100 MB/s database I/O milestone.

    Objective measurement of simulation performance requires a validated and reliable tool. However, no published Italian language assessment tool is available. Translation of a published English language tool, the Ottawa Crisis Resource Management Global Rating Scale (GRS), may lead to a validated and reliable tool. After developing an Italian language translation of the English language tool, the study measured the reliability of the new tool by comparison with the English language tool used independently in the same simulation scenarios. In addition, the validity of the Italian language tool was measured by comparison to a skills score also applied independently. The correlation coefficient between the Italian language overall GRS and the English language overall GRS was 0.82 (adjusted 95 % confidence interval: 0.62-0.92). The correlation coefficient between the Italian language overall GRS and the skill score was 0.85 (adjusted 95 % confidence interval 0.68-0.94). This study demonstrated that the Italian language GRS has acceptable reliability when compared with the English language tool, suggesting that it can be used reliably to evaluate the performance during simulated emergencies. The study also suggests that the tool has acceptable validity for assessing the simulation performance. The study suggests that the Italian language GRS translation has reasonable reliability when compared with the English language GRS and reasonable validity when compared with the assessment of the skills scores. Data suggest that the instrument is adequately reliable for informal and formative type of examinations, but may require further confirmation before use for high-stake examinations such as licensing.

    In this paper, we explore similarities and differences in hospital adverse event (AE) rates between Norway and Sweden by reviewing medical records with the Global Trigger Tool (GTT). All acute care hospitals in both countries performed medical record reviews, except one in Norway. Records were randomly selected from all eligible admissions in 2013. Eligible admissions were patients 18 years of age or older, undergoing care with an in-hospital stay of at least 24 hours, excluding psychiatric and care and rehabilitation. Reviews were done according to GTT methodology. Similar contexts for healthcare and similar socioeconomic and demographic characteristics have inspired the Nordic countries to exchange experiences from measuring and monitoring quality and patient safety in healthcare. The co-operation has promoted the use of GTT to monitor national and local rates of AEs in hospital care. 10 986 medical records were reviewed in Norway and 19 141 medical records in Sweden. No significant difference between overall AE rates was found between the two countries. The rate was 13.0% (95% CI 11.7% to 14.3%) in Norway and 14.4% (95% CI 12.6% to 16.3%) in Sweden. There were significantly higher AE rates of surgical complications in Norwegian hospitals compared with Swedish hospitals. Swedish hospitals had significantly higher rates of pressure ulcers, falls and 'other' AEs. Among more severe AEs, Norwegian hospitals had significantly higher rates of surgical complications than Swedish hospitals. Swedish hospitals had significantly higher rates of postpartum AEs. The level of patient safety in acute care hospitals, as assessed by GTT, was essentially the same in both countries. The differences between the countries in the rates of several types of AEs provide new incentives for Norwegian and Swedish governing bodies to address patient safety issues.

    Full Text Available Gram-negative pathogen–induced nosocomial infections and resistance are a most serious menace to global public health. Qingfei Xiaoyan Wan (QF, a traditional Chinese medicine (TCM formula, has been used clinically in China for the treatment of upper respiratory tract infections, acute or chronic bronchitis and pulmonary infection. In this study, the effects of QF on Pseudomonas aeruginosa–induced acute pneumonia in mice were evaluated. The mechanisms by which four typical anti-inflammatory ingredients from QF, arctigenin (ATG, cholic acid (CLA, chlorogenic acid (CGA and sinapic acid (SPA, regulate anti-inflammatory signaling pathways and related targets were investigated using molecular biology and molecular docking techniques. The results showed that pretreatment with QF significantly inhibits the release of cytokines (TNF-α and IL-6 and chemokines (IL-8 and RANTES, reduces leukocytes recruitment into inflamed tissues and ameliorates pulmonary edema and necrosis. In addition, ATG was identified as the primary anti-inflammatory agent with action on the PI3K/AKT and Ras/MAPK pathways. CLA and CGA enhanced the actions of ATG and exhibited synergistic NF-κB inactivation effects possibly via the Ras/MAPK signaling pathway. Moreover, CLA is speculated to target FGFR and MEK firstly. Overall, QF regulated the PI3K/AKT and Ras/MAPK pathways to inhibit pathogenic bacterial infections effectively.

    Liu-Shen-Wan (LSW) is a widely-used traditional Chinese medicine containing realgar (As(4)S(4)). Realgar has been included in many traditional medicines, and is often taken as arsenite for risk assessment in realgar-containing traditional remedies. Is realgar toxicologically similar to arsenite? Mice were orally given LSW (60 and 200mg/kg; 200mg LSW contains 27 mg realgar), realgar (30 mg/kg, equivalent to 21 mg As/kg), and the equivalent As dose as sodium arsenite (NaAsO(2)), or as arsenate (Na(2)HAsO(4)). Acute toxicity and tissue As accumulation were determined 8h later. Arsenite and arsenate increased serum alanine aminotransferase (ALT) levels, indicative of liver injury; blood urea nitrogen (BUN) was also increased by arsenite and arsenate, indicative of nephrotoxicity. No elevations of ALT and BUN were observed in LSW and realgar groups. Histopathology showed more damage in arsenite- and arsenate-treated liver and kidneys, while in realgar- and LSW- treated animals, only mild alterations were seen. Hepatic and renal As contents were dramatically increased to 6200 and 3350ng/g, respectively, after arsenite, but only increased to 260 and 180 ng/g after LSW. The expressions of arsenic-sensitive stress genes, namely metallothionein-1 and heme oxygenase-1, were increased after arsenite or arsenate by 3-10-folds, but were unaltered after LWS and realgar. Realgar and LSW are much less toxic than arsenite and arenate. The use of total As content to evaluate the safety of realgar-containing traditional medicines is not scientifically sound.

    The scored Patient-Generated Subjective Global Assessment tool (PG-SGA), regarded as the most appropriate means of identifying malnutrition in cancer patients, is often challenging to implement in a busy outpatient setting. We assessed the validity of an abridged version of the PG-SGA (abPG-SGA), which forgoes the physical examination, and compared its usefulness in discerning malnutrition to the full PG-SGA and Malnutrition Screening Tool (MST). The nutritional status of 90 oncology outpatients receiving chemotherapy was assessed according to SGA global rating, PG-SGA, and MST. Receiver operating characteristic (ROC) curves were generated to estimate the sensitivity and specificity of various cut-off scores for malnutrition. Thirty-six percent of patients were malnourished (SGA). The abPG-SGA yielded 94% sensitivity and 78% specificity and area under the curve (AUC) = 0.956, which was slightly lower than PG-SGA (97% sensitivity, 86% specificity, AUC = 0.967) and higher than MST (81% sensitivity, 72% specificity, AUC = 0.823). Patient reported symptoms included loss of appetite (30%), altered taste (31%), fatigue (30%), and decreased ability to perform activities of daily living (53%). In conclusion, the abPG-SGA is a practical, informative and valid tool for detecting malnutrition in the outpatient oncology setting.

    Oncology inpatients are at high risk of malnutrition. Identification of at risk patients by nutrition screening requires a practical and easy to use tool. In this study, we have compared a simple, novel nutrition screening tool designed for an oncology inpatient setting and the Malnutrition Screening Tool (MST) against the Patient-Generated Subjective Global Assessment (PG-SGA). This was an observational study to compare assessment of nutritional status by PG-SGA with nutrition screening using the Royal Marsden Nutrition Screening Tool (RMNST) and the MST. Patients were recruited from a single tertiary cancer centre. One hundred and twenty-six oncology inpatients underwent a full nutritional assessment and nutrition screening. The PG-SGA tool identified 90 (71%) patients as malnourished or at risk and 36 (29%) patients as well-nourished. The RMNST had a sensitivity of 93% and a specificity of 53%, and the MST had a sensitivity of 66% and a specificity of 83 %. Predictive value (ROC AUC) of both screening tools was excellent at 0.84 and 0.83 for RMNST and MST, respectively. This study identified a high prevalence of malnutrition in the population with 71% of patients being identified as malnourished or at risk of malnutrition. The RMNST had an excellent sensitivity for identifying patients who were malnourished or at risk of malnutrition in the inpatient setting although it had a poor specificity. The MST had a poorer sensitivity of 66 %. We would recommend that the RMNST is trialled in other oncology inpatient settings and also in the outpatient setting.

    To explore the effect and mechanism of cinnabaris and realgar in promoting awake effect of endotoxin- induced brain injury rat applied with Angong Niuhuang Wan. Normal rats implanted cortical electrode in advance were divided into 6 groups: control, model, the Angong Niuhuang Wan (AGNH, 0.4, 0.2 g · kg(-1)), the Angong Niuhuang Wan without cinnabaris and realgar (QZX-AGNH, 0.32, 0.16 g · kg(-1)). Rats in the control and model groups were given distilled water. After three days of intragastric administration, the brain injury model was injected with endotoxin through tail vein. Then trace electro-corticogram (EcoG) 1-6 h after LPS injection, and compare the power and relative power of beta (β) and delta-waves (δ) at 6 h of these groups. The content of acetylcholine (Ach) and the affinity of M-receptor (M-R) in cortex and brainstem were detected by alkaline hydroxylamine colorimetric method and radioactive ligand binding assay, respectively. AGNH (0.4, 0.2 g · kg(-1)) could increase the power and relative power of β and AGNH (0.4 g · kg(-1)) showed better action on brain electrical activation. QZX-AGNH showed weak effect on it. AGNH (0.4 g · kg(-1)) could increase the affinity of M-R in cortex and the content of Ach in brainstem. The action of QZX-AGNH was not obvious. In endotoxin-induced brain injury rats, AGNH can raise the cholinergic system function of cortex, and strengthen the uplink of cortex activation of brainstem cholinergic system, improve the level of cortical activity and enhance the activation of EcoG to promote the body's awakening. QZX-AGNH show weak effect. Cinnabaris and realgar play an important role in promoting awake effect in endotoxin-induced brain injury applied with Angong Niuhuang Wan. The mechanism may be related to cortical and brainstem cholinergic system function.

    The aim of this work is the analysis of the effects of the GHG external costs internalization in the energy systems. This may provide a useful tool to support decision makers to help reaching the energy systems sustain ability. External costs internalization has been carried out using two methods. First, CO{sub 2} externalities of different power generation technologies have been internalized to evaluate their effects on the economic competitiveness of these present and future technologies. The other method consisted of analysing and optimizing the global energy system, from an economic and environmental point of view, using the global energy optimization model generator, TIMES, with a time horizon of 50 years. Finally, some scenarios regarding environmental and economic strategic measures have been analysed. (Author)

    Realgar (As(4)S(4)) and cinnabar (HgS) are frequently included in traditional Chinese medicines and Indian Ayurvedic medicines. Both As and Hg are well known for toxic effects, and their safety is of concern. The aim of this study was to compare chronic nephrotoxicity of An-Gong-Niu-Huang Wan (AGNH), realgar and cinnabar with common arsenicals and mercurials. Mice were orally administrated with AGNH (3 g/kg, 6-fold of clinical dose), cinnabar (0.3 g/kg, amount in AGNH) and realgar (0.3 g/kg, amount in AGNH), HgCl(2) (0.118 mmol/kg, 1/10 of cinnabar), MeHg (0.012 mmol/kg, 1/100 of cinnabar), NaAsO(2) (As(3+) 0.028 mmol/kg, 1/100 of realgar) or Na(2)HAsO(4) (As(5+) 0.056 mmol/kg, 1/50 of realgar), daily for six weeks, and nephrotoxicity was examined. Animal body weights were decreased by MeHg and HgCl(2). Blood urea nitrogen and creatinine levels were elevated by MeHg. Renal pathology was severe in the MeHg and HgCl(2) groups, moderate in the arsenite, arsenate and realgar groups and mild in the cinnabar and AGNH groups. Renal Hg accumulation in the MeHg and HgCl(2) groups was 50-200 folds higher than the cinnabar group. Expressions of metallothionein-1 and heme oxygenase-1, biomarkers for metal toxicity, were increased 2-5 folds by arsenite, arsenate, MeHg and HgCl(2), but not by realgar, cinnabar and AGNH. The chemokine and glutathione-S transferase-α4, markers for inflammation, were also increased by MeHg and HgCl(2). Expressions of cell adhesion gene S100a9 and E-cadherin were altered by HgCl(2), arsenite and realgar. Taken together, chemical forms of mercury and arsenic are major determinants in their disposition and toxicity.

    The objective of this study was to develop and pilot a hospital self-assessment tool and prioritization system for hospitals to evaluate their pharmacy practice performance against the International Pharmaceutical Federation (FIP)'s Basel Statements. To develop the self-assessment tool, we reviewed the Basel statements to identify characteristics that could be measured at the individual hospital level and finalized these based on feedback from five cognitive interviews. The survey instrument was pilot tested in four countries; two high-, one lower middle- and one low-income country. Participants were electronically sent the survey tool and enrolled through the snowball sampling method. Tiers were developed by investigators to assist hospitals in prioritizing the achievement of Basel Statement practices. Tiers were validated by the Hospital Section chairs of FIP through a card sorting exercise. Simple agreement and Cohen's kappa was used to characterize inter-rater reliability. Descriptive statistics were used to characterize the responses. Forty-four survey responses were collected from 36 hospitals in four countries. The survey response rate was 29% and took an average of 26 minutes to complete. The overall average agreement of constructs was 83%. The survey characterized how far a hospital was to achieving the Basel Statement practices with an average achievement rate of 57% (ranging from 30% to 90%). The survey highlighted medication safety challenges facing the pharmacy profession. The results produced a benchmarking report for each respondent. The results support the validity and reliability of the survey tool. This comprehensive survey tool can be used by institutions to track their progress towards achieving the Basel Statement practices. © 2015 Royal Pharmaceutical Society.

    Full Text Available BACKGROUND: Achieving national reductions in greenhouse gas emissions will require public support for climate and energy policies and changes in population behaviors. Audience segmentation--a process of identifying coherent groups within a population--can be used to improve the effectiveness of public engagement campaigns. METHODOLOGY/PRINCIPAL FINDINGS: In Fall 2008, we conducted a nationally representative survey of American adults (n = 2,164 to identify audience segments for global warming public engagement campaigns. By subjecting multiple measures of global warming beliefs, behaviors, policy preferences, and issue engagement to latent class analysis, we identified six distinct segments ranging in size from 7 to 33% of the population. These six segments formed a continuum, from a segment of people who were highly worried, involved and supportive of policy responses (18%, to a segment of people who were completely unconcerned and strongly opposed to policy responses (7%. Three of the segments (totaling 70% were to varying degrees concerned about global warming and supportive of policy responses, two (totaling 18% were unsupportive, and one was largely disengaged (12%, having paid little attention to the issue. Certain behaviors and policy preferences varied greatly across these audiences, while others did not. Using discriminant analysis, we subsequently developed 36-item and 15-item instruments that can be used to categorize respondents with 91% and 84% accuracy, respectively. CONCLUSIONS/SIGNIFICANCE: In late 2008, Americans supported a broad range of policies and personal actions to reduce global warming, although there was wide variation among the six identified audiences. To enhance the impact of campaigns, government agencies, non-profit organizations, and businesses seeking to engage the public can selectively target one or more of these audiences rather than address an undifferentiated general population.

    Full Text Available Intergrated Forest for Conservation Education of Wan Abdul Rachman (IFCE WAR Great Forest Park is a conservation forest zone which has natural area and cultivated area. The natural area in Wan Abdul Rachman Great Forest Park consists of secondary forest, whereas the cultivated area consists of agroforestry with cacao plants and agroforestry with coffee plants. The different land use in both areas caused the difference in carbon sink specifically in litter and soil. The research was aimed to study the difference of litter and soil carbon stock in natural and cultivated area in IFCE WAR Great Forest Park. The observation plots included in the current study was determined using purposive sampling method. The research was conducted in June until August 2015. Data was analyzed using analysis of variance and continued with honestly significant difference test. The results showed that there was no difference of litter carbon stock in cultivated area and natural area in IFCE WAR Great Forest Park, whereas the soil carbon stock in natural area was higher than that in cultivated area.

  9. A global conformance quality model. A new strategic tool for minimizing defects caused by variation, error, and complexity

    The performance of Japanese products in the marketplace points to the dominant role of quality in product competition. Our focus is motivated by the tremendous pressure to improve conformance quality by reducing defects to previously unimaginable limits in the range of 1 to 10 parts per million. Toward this end, we have developed a new model of conformance quality that addresses each of the three principle defect sources: (1) Variation, (2) Human Error, and (3) Complexity. Although the role of variation in conformance quality is well documented, errors occur so infrequently that their significance is not well known. We have shown that statistical methods are not useful in characterizing and controlling errors, the most common source of defects. Excessive complexity is also a root source of defects, since it increases errors and variation defects. A missing link in the defining a global model has been the lack of a sound correlation between complexity and defects. We have used Design for Assembly (DFA) methods to quantify assembly complexity and have shown that assembly times can be described in terms of the Pareto distribution in a clear exception to the Central Limit Theorem. Within individual companies we have found defects to be highly correlated with DFA measures of complexity in broad studies covering tens of millions of assembly operations. Applying the global concepts, we predicted that Motorola`s Six Sigma method would only reduce defects by roughly a factor of two rather than orders of magnitude, a prediction confirmed by Motorola`s data. We have also shown that the potential defects rates of product concepts can be compared in the earliest stages of development. The global Conformance Quality Model has demonstrated that the best strategy for improvement depends upon the quality control strengths and weaknesses.

    The past decade has been witness to two mega-tsunami events, 2004 Indian ocean tsunami and 2011 Japan tsunami and multiple major tsunami events; 2006 Java, Kuril Islands, 2007 Solomon Islands, 2009 Samoa and 2010 Chile, to name a few. These events generated both local and far field tsunami inundations with runup ranging from a few meters to around 40 m in the coastal impact regions. With a majority of the coastal population at risk, there is need for a sophisticated outlook towards catastrophe risk estimation and a quick mitigation response. At the same time tools and information are needed to aid advanced tsunami hazard prediction. There is an increased need for insurers, reinsurers and Federal hazard management agencies to quantify coastal inundations and vulnerability of coastal habitat to tsunami inundations. A novel tool is developed to model local and far-field tsunami generation, propagation and inundation to estimate tsunami hazards. The tool is a combination of the NOAA MOST propagation database and an efficient and fast GPU (Graphical Processing Unit)-based non-linear shallow water wave model solver. The tsunamigenic seismic sources are mapped on to the NOAA unit source distribution along subduction zones in the ocean basin. Slip models are defined for tsunamigenic seismic sources through a slip distribution on the unit sources while maintaining limits of fault areas. A GPU based finite volume solver is used to simulate non-linear shallow water wave propagation, inundation and runup. Deformation on the unit sources provide initial conditions for modeling local impacts, while the wave history from propagation database provides boundary conditions for far field impacts. The modeling suite provides good agreement with basins for basin wide tsunami propagation to validate local and far field tsunami inundations.

    The use of simulation-based assessments for high-stakes physician examinations remains controversial. The Managing Emergencies in Paediatric Anaesthesia course uses simulation to teach evidence-based management of anesthesia crises to trainee anesthetists in the United Kingdom (UK) and Canada. In this study, we investigated the feasibility and reliability of custom-designed scenario-specific performance checklists and a global rating scale (GRS) assessing readiness for independent practice. After research ethics board approval, subjects were videoed managing simulated pediatric anesthesia crises in a single Canadian teaching hospital. Each subject was randomized to two of six different scenarios. All 60 scenarios were subsequently rated by four blinded raters (two in the UK, two in Canada) using the checklists and GRS. The actual and predicted reliability of the tools was calculated for different numbers of raters using the intraclass correlation coefficient (ICC) and the Spearman-Brown prophecy formula. Average measures ICCs ranged from 'substantial' to 'near perfect' (P ≤ 0.001). The reliability of the checklists and the GRS was similar. Single measures ICCs showed more variability than average measures ICC. At least two raters would be required to achieve acceptable reliability. We have established the reliability of a GRS to assess the management of simulated crisis scenarios in pediatric anesthesia, and this tool is feasible within the setting of a research study. The global rating scale allows raters to make a judgement regarding a participant's readiness for independent practice. These tools may be used in the future research examining simulation-based assessment. © 2013 John Wiley & Sons Ltd.

    The Institute for Healthcare Improvement encourages use of the Global Trigger Tool to objectively determine and monitor adverse events (AEs). Baylor Health Care System (BHCS) is an integrated healthcare delivery system in North Texas. The Global Trigger Tool was applied to BHCS's eight general acute care hospitals, two inpatient cardiovascular hospitals and two rehabilitation/long-term acute care hospitals. Data were collected from a monthly random sample of charts for each facility for patients discharged between 1 July 2006 and 30 June 2007 by external professional nurse auditors using an MS Access Tool developed for this initiative. In addition to the data elements recommended by Institute for Healthcare Improvement, BHCS developed fields to permit further characterisation of AEs to identify learning opportunities. A structured narrative description of each identified AE facilitated text mining to further characterise AEs. INITIAL FINDINGS: Based on this sample, AE rates were found to be 68.1 per 1000 patient days, or 50.8 per 100 encounters, and 39.8% of admissions were found to have ≥1 AE. Of all AEs identified, 61.2% were hospital-acquired, 10.1% of which were associated with a National Coordinating Council - Medical Error Reporting and Prevention harm score of "H or I" (near death or death). To enhance learning opportunities and guide quality improvement, BHCS collected data-such as preventability and AE source-to characterise the nature of AEs. Data are provided regularly to hospital teams to direct quality initiatives, moving from a general focus on reducing AEs to more specific programmes based on patterns of harm and preventability.

    Situation awareness (SA) is a vital construct for decision making in intense, dynamic environments such as trauma resuscitation. Human patient simulation (HPS) allows for a safe environment where individuals can develop these skills. Trauma resuscitation is performed by multidisciplinary teams that are traditionally difficult to globally assess. Our objective was to create and validate a novel tool to measure SA in multidisciplinary trauma teams using a HPS--the Team Situation Awareness Global Assessment Technique (TSAGAT). Memorial University Simulation Centre. Using HPS, 4 trauma teams completed 2 separate trauma scenarios. Student, junior resident, senior resident, and attending staff teams each had 3 members (trauma team leader, nurse, and airway manager). Individual SAGATs were developed by experts in each respective field and contained shared and complimentary knowledge questions. Teams were assessed with SAGAT in real time and with traditional checklists using video review. TSAGAT was calculated as the sum of individual SAGAT scores and was compared with the traditional checklist scores. Shared, complimentary, and TSAGAT scores improved with increasing team experience. Differences between teams for TSAGAT and complimentary knowledge were statistically significant (p differences between teams also reached statistical significance (p < 0.05). TSAGAT scores correlated strongly with traditional checklist scores (Pearson correlation r = 0.996). Interrater reliability for the checklist tool was high (Pearson correlation r = 0.937). TSAGAT is the first valid and reliable assessment tool incorporating SA and HPS for multidisciplinary team performance in trauma resuscitation. TSAGAT could compliment or improve on current assessment methods and curricula in trauma and critical care and provides a template for team assessment in other areas of surgical education.

    The Soil and Water Assessment Tool (SWAT) is one of the most widely used watershed-scale water quality models in the world. Over 2,000 peer-reviewed SWAT-related journal articles have been published and hundreds of other studies have been published in conference proceedings and other formats. The use of SWAT was initially concentrated in North America and Europe but has also expanded dramatically in other countries and regions during the past decade including Brazil, China, India, Iran, South Korea, Southeast Asia and eastern Africa. The SWAT model has proven to be a very flexible tool for investigating a broad range of hydrologic and water quality problems at different watershed scales and environmental conditions, and has proven very adaptable for applications requiring improved hydrologic and other enhanced simulation needs. We investigate here the various technological, networking, and other factors that have supported the expanded use of SWAT, and also highlight current worldwide simulation trends and possible impediments to future increased usage of the model. Examples of technological advances include easy access to web-based documentation, user-support groups, and SWAT literature, a variety of Geographic Information System (GIS) interface tools, pre- and post-processing calibration software and other software, and an open source code which has served as a model development catalyst for multiple user groups. Extensive networking regarding the use of SWAT has further occurred via internet-based user support groups, model training workshops, regional working groups, regional and international conferences, and targeted development workshops. We further highlight several important model development trends that have emerged during the past decade including improved hydrologic, cropping system, best management practice (BMP) and pollutant transport simulation methods. In addition, several current SWAT weaknesses will be addressed and key development needs will be

    Using multiple historical satellite surface soil moisture products, the Kalman Filtering-based Soil Moisture Analysis Rainfall Tool (SMART) is applied to improve the accuracy of a multi-decadal global daily rainfall product that has been bias-corrected to match the monthly totals of available rain gauge observations. In order to adapt to the irregular retrieval frequency of heritage soil moisture products, a new variable correction window method is developed which allows for better efficiency in leveraging temporally sparse satellite soil moisture retrievals. Results confirm the advantage of using this variable window method relative to an existing fixed-window version of SMART over a range of accumulation periods. Using this modified version of SMART, and heritage satellite surface soil moisture products, a 1.0-degree, 1979-1998 global rainfall dataset over land is corrected and validated. Relative to the original precipitation product, the updated correction scheme demonstrates improved root-mean-square-error and correlation accuracy and provides a higher probability of detection and lower false alarm rates for 3-day rainfall accumulation estimates, except for the heaviest (99th percentile) cases. This corrected rainfall dataset is expected to provide improved rainfall forcing data for the land surface modeling community.

    Hand eczema is an impacting cutaneous disease. Globally valid tools that help to diagnose hand and forearm eczema are required. To validate the questions to detect hand and/or forearm eczema included in the "Nordic Occupational Skin Questionnaire" (NOSQ-2002) in the Spanish language. A prospective pilot study was conducted with 80 employees of a cleaning company and a retrospective one involving 2,546 individuals. The responses were analysed for sensitivity, specificity and positive and negative predictive values. The final diagnosis according to the patients' hospital records, the specialty care records and the physical examination was taken as gold standard. The Dermatology Life Quality Index (DLQI) was also evaluated. Sensitivity and specificity, in a worst case scenario (WC) combining both questions, were 96.5% and 66.7%, respectively, and in a per protocol (PP) analysis, were 96.5% and 75.2%. The questions validated detected eczema effectively, making this tool suitable for use e.g. in multicentre epidemiological studies or clinical trials.

    The Chi-Jia-Wan Stream watershed, located in the area of the upstream Da-Chia River in central Taiwan, is famous for slopeland agriculture and the land-locked salmon. Improper agricultural activities have caused apparent ecosystem vulnerability and sensitivity. In this study, a system that combined three watershed-based environmental indicators with multiple-criteria decision-making techniques, the Analytical Hierarchy Process, and the Preference Ranking Organization METHod for Enrichment Evaluations was developed to assess eco-environmental vulnerability. The composite evaluation index system was set up including sediment, runoff, and nutrient factors. Supported by geographic information system and K-means clustering and taking the subwatershed as the evaluation unit, the vulnerability is classified into four levels: potential, low, moderate, and high. The evaluated results show that 8.82% of subwatersheds (six subwatersheds) are in the moderately and highly vulnerable zones. These subwatersheds represent vertical-belt distribution, mainly concentrated in the right side of the studied area and near the riparian zone along the Chi-Jia-Wan Stream. The exploited farmland in the moderately and highly vulnerable zones is about 142.21 ha, occupying 75.38% of the total farmland in the studied watershed. These seriously vulnerable zones that have caused degradation in the quality of the eco-environment should be treated with more best management practices for eco-environmental rehabilitation. Additionally, the proposed model can effectively evaluate the eco-environmental vulnerability grade for reference in policy planning and ecological restoration in this area.

    Now that there is overwhelming evidence of global climate change, scientists, managers and planners (i.e. practitioners) need to assess the potential impacts of climate change on particular ecological systems, within specific geographic areas, and at spatial scales they care about, in order to make better land management, planning, and policy decisions. Unfortunately, this application of climate science to real world decisions and planning has proceeded too slowly because we lack tools for translating cutting-edge climate science and climate-model outputs into something managers and planners can work with at local or regional scales (CCSP 2008). To help increase the accessibility of climate information, we have developed a freely-available, easy-to-use, web-based climate-change analysis toolbox, called ClimateWizard, for assessing how climate has and is projected to change at specific geographic locations throughout the world. The ClimateWizard uses geographic information systems (GIS), web-services (SOAP/XML), statistical analysis platforms (e.g. R- project), and web-based mapping services (e.g. Google Earth/Maps, KML/GML) to provide a variety of different analyses (e.g. trends and departures) and outputs (e.g. maps, graphs, tables, GIS layers). Because ClimateWizard analyzes large climate datasets stored remotely on powerful computers, users of the tool do not need to have fast computers or expensive software, but simply need access to the internet. The analysis results are then provided to users in a Google Maps webpage tailored to the specific climate-change question being asked. The ClimateWizard is not a static product, but rather a framework to be built upon and modified to suit the purposes of specific scientific, management, and policy questions. For example, it can be expanded to include bioclimatic variables (e.g. evapotranspiration) and marine data (e.g. sea surface temperature), as well as improved future climate projections, and climate-change impact

    The recent adoption of World Health Assembly Resolution 60.22, titled "Health Systems: Emergency Care Systems," has established an important health care policy tool for improving emergency care access and availability globally. The resolution highlights the role that strengthened emergency care systems can play in reducing the increasing burden of disease from acute illness and injury in populations across the socioeconomic spectrum and calls on governments and the World Health Organization to take specific and concrete actions to make this happen. This resolution constitutes recognition by the World Health Assembly of the growing public health role of emergency care systems and is the highest level of international attention ever devoted to emergency care systems worldwide. Emergency care systems for secondary prevention of acute illnesses and injury remain inadequately developed in many low- and middle-income countries, despite evidence that basic strategies for improving emergency care systems can reduce preventable mortality and morbidity and can in many cases also be cost-effective. Emergency care providers and their professional organizations have used their comprehensive expertise to strengthen emergency care systems worldwide through the development of tools for emergency medicine education, systems assessment, quality improvement, and evidence-based clinical practice. World Health Assembly 60.22 represents a unique opportunity for emergency care providers and other advocates for improved emergency care to engage with national and local health care officials and policymakers, as well as with the World Health Organization, and leverage the expertise within the international emergency medicine community to make substantial improvements in emergency care delivery in places where it is most needed.

    The aim was to describe the strengths and weaknesses, from team member perspectives, of working with the Global Trigger Tool (GTT) method of retrospective record review to identify adverse events causing patient harm. A qualitative, descriptive approach with focus group interviews using content analysis. 5 Swedish hospitals in 2011. 5 GTT teams, with 5 physicians and 11 registered nurses. 5 focus group interviews were carried out with the five teams. Interviews were taped and transcribed verbatim. 8 categories emerged relating to the strengths and weaknesses of the GTT method. The categories found were: Usefulness of the GTT, Application of the GTT, Triggers, Preventability of harm, Team composition, Team tasks, Team members' knowledge development and Documentation. Gradually, changes in the methodology were made by the teams, for example, the teams reported how the registered nurses divided up the charts into two sets, each being read respectively. The teams described the method as important and well functioning. Not only the most important, but also the most difficult, was the task of bringing the results back to the clinic. The teams found it easier to discuss findings at their own clinics. The GTT method functions well for identifying adverse events and is strengthened by its adaptability to different specialties. However, small, gradual methodological changes together with continuingly developed expertise and adaption to looking at harm from a patient's perspective may contribute to large differences in assessment over time.

    Novel drug delivery systems have previously never been used in the formulation of any crude unfractionated traditional Chinese medicine. In the present study, a multi-unit drug delivery system (MUDDS) for a Chinese medicine Niuhuang Xingxiao Wan (NXW) was prepared using micro/nanotechnologies to enhance the bioavailability and efficacy. NXW was formulated into four units, that is, realgar, frankincense and myrrh oil (FMO), musk, and bezoar. The four units were processed using the wet ball milling, high-pressure homogenization, liquid nitrogen freezing-ultracentrifugation trituration, and dry grinding methods, respectively. After formulation, the four independent units prepared were encapsulated together to obtain the final NXW-MUDDS. Pharmacokinetic studies showed that the area under the plasma concentration-time curve (AUC), terminal half-life (T1/2), and time to reach the peak plasma concentration (Tmax) following administration of NXW-MUDDS were 5.21, 1.96, and 1.99 times higher, respectively, than that of NXW. The in vivo antitumor activity assay showed that the efficacy of NXW-MUDDS was significantly higher (Pnanotechnologies in formulating Chinese medicines. Copyright © 2015 Elsevier B.V.

    Full Text Available Chronic kidney disease (CKD is a worldwide health problem with growing prevalence in developing countries. Renal tubular epithelial-mesenchymal transition (EMT is a critical step and key factor in the development of this condition. Renal tubulointerstitial fibrosis is a basic pathological change at the later stages of the disease. Therefore, blocking the development of EMT could be a critical factor in curing CKD. We have established a cell-based high-content screening (HCS method to identify inhibitors of EMT in human proximal tubular epithelial (HK-2 cells by automatic acquisition and processing of dual-fluorescent labeled images. With the aid of chromatographic separation and mass spectrometry, we achieved the rapid and reliable screening of active compounds from the Chinese herbal medicine Tong-Mai-Yang-Xin-Wan (TMYX for treating EMT. Five fractions were found to exert anti-EMT activity and were further identified by liquid chromatography coupled with tandem mass spectrometry. Glycyrrhizic acid, glyasperin A, and licorisoflavan A were found to inhibit EMT. The proposed approach was successfully applied to screen active compounds from TMYX on TGF-β1-stimulated HK-2 cells and may offer a new means for identifying lead compounds for treating EMT from registered Chinese herbal medicines.

    Full Text Available Hu-Lu-Ba-Wan (HLBW is a Chinese herbal prescription used to treat kidney deficiency. The aim of this study was to explore the effect and mechanism of HLBW on diabetic nephropathy (DN in type 2 diabetic rats. The rat model of DN was established by being fed a high-fat diet and intravenous injection of streptozotocin. Then, HLBW decoction was administered for 16 weeks. Blood glucose level, lipid profile, renal function, 24-hour total urinary protein, and albumin content were examined. Renal morphology and superoxide anion levels were evaluated. The activity of nicotinamide-adenine dinucleotide phosphate (NADPH and protein kinase C-alpha (PKC-α related genes expression in renal tissue were also determined. Our data demonstrated that HLBW significantly improved hyperglycemia, hyperlipidemia, and proteinuria in diabetic rats compared with those of control group. HLBW also alleviated glomerular expansion and fibrosis, extracellular matrix accumulation and effacement of the foot processes. Additionally, HLBW reduced superoxide anion level, NADPH oxidase activity, the protein and mRNA expressions of p47phox, and the protein expression of phosphorylated PKC-α in renal tissue. These results suggest that HLBW is effective in the treatment of DN in rats. The underlying mechanism may be related to the attenuation of renal oxidative stress via PKC-α/NADPH oxidase signaling pathway.

    An-Gong-Niu-Huang Wan (AGNH) is a famous traditional Chinese medicine prescription that contains cinnabar (HgS) and realgar (As 2 S 2 ); the clinical practice of AGNH is hindered because both mercury and arsenic are hepatorenal toxic metalloids. It is noted that the cinnabar and realgar in AGNH are not used alone, but rather combined with different kinds of medicinal herbs as a formula to use. In this study, we evaluated the hepatorenal protective effects of the medicinal herbs in AGNH after co-exposure to cinnabar and realgar for 4 weeks in mice. The combination of the herbs in AGNH alleviated cinnabar and realgar-induced histopathological alterations and oxidative stress in the liver and kidneys. Furthermore, in cinnabar and realgar-treated mice, the increased expression levels of inducible enzymes (COX-2 and iNOS) and proinflammatory mediators (IL-1β, TNF-α, PGE2 and NO) in the liver and kidneys were consistently down-regulated when medicinal herbs were combined as a formula. We also found that the herbs could reduce the inflammatory response by the inactivation of the MAPK and PI3K/Akt signaling pathway and the resulting blockade of NF-κB activation. Overall, our data indicates that the herbal medicines in AGNH attenuate cinnabar and realgar-induced hepatorenal toxicity by improving antioxidant competence and suppressing inflammatory injury.

    Full Text Available The present study explored the feasible pathway of Si Shen Wan (SSW in inhibiting apoptosis of intestinal epithelial cells (IECs by observing activation of phospholipase Cγ-1 (PLC-γ1 and PI3K/Akt signal in colonic mucosa from rats with colitis. Experimental colitis was induced by 2,4,6-trinitrobenzene sulfonic acid (TNBS in the Sprague-Dawley rats. After SSW was administrated for 7 days after TNBS infusion, western blot showed an increment in levels of PI3K, p-Akt, and IL-23 and a decrement in levels of PLC-γ1 and HSP70 in colonic mucosal injury induced by TNBS. Meanwhile, assessments by ELISA revealed an increment in concentrations of IL-2, IL-6, and IL-17 and a reduction in level of TGF-β after TNBS challenge. Impressively, treatment with SSW for 7 days significantly attenuated the expressions of PI3K and p-Akt and the secretion of IL-2, IL-6, IL-17, and IL-23 and promoted the activation of PLC-γ1, HSP70, and TGF-β. Our previous studies had demonstrated that SSW restored colonic mucosal ulcers by inhibiting apoptosis of IECs. The present study demonstrated that the effect of SSW on inhibiting apoptosis of IECs was realized probably by activation of PLC-γ1 and suppression of PI3K/Akt signal pathway.

    Full Text Available The aim of the study was to explore the possible mechanisms that Guizhi Fuling Wan (GFW enhances the sensitivity of the SKOV3/DDP ovarian cancer cells and the resistant xenograft tumours to cisplatin. Rat medicated sera containing GFW were prepared by administering GFW to rats, and the primary bioactive constituents of the sera were gallic acid, paeonol, and paeoniflorin analysed by HPLC/QqQ MS. Cell counting kit-8 analysis was shown that coincubation of the sera with cisplatin/paclitaxel enhanced significantly the cytotoxic effect of cisplatin or paclitaxel in SKOV3/DDP cells. The presence of the rat medicated sera containing GFW resulted in an increase in rhodamine 123 accumulation by flow cytometric assays and a decrease in the protein levels of P-gp, phosphorylation of AKT at Ser473, and mTOR in a dose-dependent manner in SKOV3/DDP cells by western blot analysis, but the sera had no effect on the protein levels of PI3K p110α and total AKT. The low dose of GFW enhanced the anticancer efficacy of cisplatin and paclitaxel treatment in resistant SKOV3/DDP xenograft tumours. GFW could sensitize cisplatin-resistant SKOV3/DDP cells by inhibiting the protein level and function of P-gp, which may be medicated through inactivation of the PI3K/AKT/mTOR pathway.

    Incontinence-associated dermatitis (IAD) is a specific type of irritant contact dermatitis with different levels of severity. An internationally accepted instrument to assess the severity of IAD in adults with established diagnostic accuracy, agreement, and reliability is needed to support clinical practice and research. To design and psychometrically evaluate the Ghent Global IAD Categorisation Tool (GLOBIAD). The design was based on expert consultation using a three-round Delphi procedure with 34 experts from 13 countries. The instrument was tested using IAD photographs reflecting different severity levels in a sample of 823 health professionals in 30 countries. Measures for diagnostic accuracy (sensitivity and specificity), agreement, inter-rater reliability (multi-rater Fleiss kappa), and intra-rater reliability (Cohen's Kappa) were assessed. The GLOBIAD consists of two categories according to the presence of persistent redness (Cat.1) and skin loss (Cat.2), both subdivided based on the presence of clinical signs of infection. The agreement for differentiating between Cat.1 and Cat.2 was 0.86 [95% confidence interval (CI) 0.86-0.87], with a sensitivity of 90% and a specificity of 84%. The overall agreement was 0.55 (95%CI 0.55-0.56). The Fleiss Kappa for differentiating between Cat.1 and Cat.2 was 0.65 (95%CI 0.65-0.65). The overall Fleiss Kappa was 0.41 (95%CI 0.41-0.41). The Cohen's Kappa for differentiating between Cat.1 and Cat.2 was 0.76 (95%CI 0.75-0.77). The overall Cohen's Kappa was 0.61 (95%CI 0.59-0.62). The development of the GLOBIAD is a major step forward towards a better systematic assessment of IAD in clinical practice and research worldwide. Further validation is however needed.

    achieve source-to-sink high-performance flows, and (2) develop tools that provide these capabilities through simple interfaces to users and applications. In terms of the former, we propose to develop (1) optimization methods that align and transition multiple storage flows to multiple network flows on multicore, multibus hosts; and (2) edge and long-haul network path realization and maintenance using advanced provisioning methods including OSCARS and OpenFlow. We also propose synthesis methods that combine these individual technologies to compose high-performance flows using a collection of constituent storage-network flows, and realize them across the storage and local network connections as well as long-haul connections. We propose to develop automated user tools that profile the hosts, storage systems, and network connections; compose the source-to-sink complex flows; and set up and maintain the needed network connections. These solutions will be tested using (1) 100 Gbps connection(s) between Oak Ridge National Laboratory (ORNL) and Argonne National Laboratory (ANL) with storage systems supported by Lustre and GPFS file systems with an asymmetric connection to University of Memphis (UM); (2) ORNL testbed with multicore and multibus hosts, switches with OpenFlow capabilities, and network emulators; and (3) 100 Gbps connections from ESnet and their Openflow testbed, and other experimental connections. This proposal brings together the expertise and facilities of the two national laboratories, ORNL and ANL, and UM. It also represents a collaboration between DOE and the Department of Defense (DOD) projects at ORNL by sharing technical expertise and personnel costs, and leveraging the existing DOD Extreme Scale Systems Center (ESSC) facilities at ORNL.

    Sulfur fumigation can induce chemical transformation of bioactive components, consequently the alteration of bioactivities or even toxicities of medicinal herbs. Inspecting Chinese patent medicines (CPM) contained sulfur-fumigated constituent herbs is crucial for ensuring the safety and efficacy of CPM. Paeonifiorin sulfonate is a sulfur-fumigation induced compound of Moutan Cortex (MC), one of the main constituent herbs of a commonly used CPM Liu-Wei-Di-Huang-Wan (LWDHW). Herein, we investigated the approach of paeonifiorin sulfonate as a characteristic marker for specifically inspecting LWDHW potentially contained sulfur-fumigated MC (SFMC). First, mimic LWDHW samples contained SFMC (SFMC-LWDHW) and non-fumigated MC (NFMC-LWDHW) were prepared respectively. Second, an LC-MS method was developed and validated to qualitatively and quantitatively determine paeonifiorin sulfonate in the mimic LWDHW samples. Third, the established method was applied to analyze the commercial LWDHW samples. The results showed that paeoniflorin sulfonate could only be detectable in SFMC-LWDHW, but not in NFMC-LWDHW samples. The CPM matrix could enhance the response of paeoniflorin sulfonate in mass spectrometry analysis. In addition, the LOQ, linearity, precision, accuracy and stability were also demonstrated to be acceptable for quantifying paeoniflorin sulfonate in LWDHW. Commercial samples analysis indicated that paeoniflorin sulfonate were detectable in 9 of 10 commercial LWDHW samples, with the content varied between 105.53μg/g and 438.61μg/g. All the results suggested that paeoniflorin sulfonate could be used as a characteristic and reliable chemical marker for specifically inspecting commercial LWDHW contained SFMC. This study also provides a new strategy for the quality control of other CPMs potentially produced from sulfur-fumigated constituent herbs. Copyright © 2017 Elsevier B.V. All rights reserved.

    An-gong-niu-huang wan (AGNH) is a famous traditional Chinese medicine used for brain trauma, hemorrhage, and coma. AGNH contains 10% realgar (As₄S₄) and 10% cinnabar (HgS). Both As and Hg are well-known for their toxic effects, and the safety of AGNH is of concern. To address this question, the acute toxicity of AGNH, realgar and cinnabar were compared to sodium arsenite (NaAsO₂) and mercuric chloride (HgCl₂). Mice were administrated orally AGNH at 1, 3 and 6g/kg. AGNH at 3g/kg contains 2.8mmol As/kg as realgar and 1.18mmol Hg/kg as cinnabar. Realgar, cinnabar, arsenite (0.28 mmol/kg, 10% of realgar) and HgCl₂ (0.256 mmol/kg, 20% of cinnabar) were orally given to mice for comparison. Blood and tissues were collected 8h later for toxicity evaluation. Serum alanine aminotransferase was increased by arsenite and blood urea nitrogen was increased by HgCl₂. Total As accumulation after arsenite in liver (100-fold) and kidney (13-fold) was much higher than that after realgar. The accumulation of Hg after HgCl₂ in liver was 400-fold higher and kidney 30-fold higher than after cinnabar. Histopathology showed moderate liver and kidney injuries after arsenite and HgCl₂, but injuries were mild or absent after AGNH, realgar, and cinnabar. The expression of metallothionein-1, a biomarker of metal exposure, was increased 4-10-fold by arsenite and HgCl₂, but was unchanged by AGNH, realgar and cinnabar. Thus, AGNH, realgar and cinnabar are much less toxic acutely than arsenite and HgCl₂. The chemical forms of As and Hg are extremely important factors in determining their disposition and toxicity.

    Realgar-containing traditional Chinese medicines such as Xiao-Er-Zhi-Bao-Wan (XEZBW), have been widely used for thousands of years. However, events associated with arsenic-induced ailments have increasingly become a public concern. To address the toxicity of XEZBW, we studied the histopathology and blood biochemistry of rats exposed to XEZBW using technology like high-performance liquid chromatography-inductively coupled mass spectrometry to determine arsenic speciation. Our results demonstrated that dimethylarsinic acid (DMA) increased from 18.57 ± 7.45 to 22.74 ± 7.45 ng/g in rat kidney after oral administration for 7 and 14 days, which was 10-fold higher than the levels observed in controls. Trivalent arsenite As(III) showed a large increase on day 7 (26.99 ± 1.98 ng/g), followed by a slight decrease on day 14 (13.67 ± 6.48 ng/g). Total arsenic levels on day 7 (185.52 ± 24.56 ng/g) and day 14 (198.57 ± 26.26 ng/g) were nearly twofold higher than that in the control group (92.77 ± 14.98 ng/g). Histopathological analysis showed mild injury in the liver and kidney of rats subjected to oral administration of realgar for 14 days. As in the XEZBW groups, a mild injury in these organs was observed after administration for 14 days. This study inferred that the toxicity of arsenic was concentration- and time-dependent. The accumulation of DMA, a byproduct of choline metabolism, was responsible for inducing higher toxicity. Therefore, we concluded that measuring the levels of DMA, instead of total arsenic, might be more suitable for evaluating the toxicity of realgar-containing traditional Chinese medicines.

    The aim of this study was to investigate the effects of using the Yo-Yo intermittent recovery test level 1 (Yo-Yo IR1) as a high intensity training tool for sedentary university female students. Baseline measures were recorded for body fat percentage, Wingate Anaerobic Test (WAnT) peak power and mean power, and Yo-Yo IR1 performance. Subjects were matched in pairs for body fat percentage and then randomly allocated to the intervention group (INT) (n=12) or control group (CON) (n=13). The INT undertook a 6-week training programme twice a week using the Yo-Yo IR1. The CON undertook no training. The INT increased their Yo-Yo IR1 performance (230±38m baseline vs 403±152m post-training), WAnT peak power (970±176 Watts baseline vs 1148±159 Watts post-training), and WAnT mean power (399±55 Watts baseline vs 439±53 Watts post-training) (p0.05). The results of this study show that a 6-week high intensity intermittent training programme using the Yo-Yo IR1 as a training intervention increases both aerobic and anaerobic capacity in a sedentary female population.

    Jiao-Tai-Wan (JTW), composed of Rhizome Coptidis and Cortex Cinnamomi, is a classical traditional Chinese prescription for treating insomnia. Several in vivo studies have concluded that JTW could exert its therapeutical effect in insomnia rats. However, the specific mechanism is still unclear. The present study aimed to explore the effect of JTW on sleep in obesity-resistant (OR) rats with chronic partial sleep deprivation (PSD) and to clarify its possible mechanism. JTW was prepared and the main components contained in the granules were identified by 3D-High Performance Liquid Chromatography (3D-HPLC) assay. The Male Sprague-Dawley (SD) rats underwent 4 h PSD by environmental noise and the treatment with low and high doses of JTW orally for 4 weeks, respectively. Then sleep structure was analyzed by electroencephalographic (EEG). Inflammation markers including high-sensitivity C reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) levels were examined in the rat plasma. Meanwhile, metabolic parameters as body weight increase rate, fasting plasma glucose (FPG), fasting insulin (FINS) levels and insulin resistance index (HOMA-IR) were measured. The expressions of clock gene cryptochromes (Cry1 and Cry2) and inflammation gene nuclear factor-κB (NF-κB) in peripheral blood monocyte cells (PBMC) were also determined. The result showed that the administration of JTW significantly increased total sleep time and total slow wave sleep (SWS) time in OR rats with PSD. Furthermore, the treatment with JTW reversed the increase in the markers of systemic inflammation and insulin resistance caused by sleep loss. These changes were also associated with the up-regulation of Cry1 mRNA and Cry 2 mRNA and the down-regulation of NF-κB mRNA expression in PBMC. This study suggests that JTW has the beneficial effects of improving sleep, inflammation and insulin sensitivity. The mechanism appears to be related to the modulation of circadian clock and

  2. Developing a scorecard to assess global progress in scaling up diarrhea control tools: a qualitative study of academic leaders and implementers.

    Full Text Available BACKGROUND: In 2010, diarrhea caused 0.75 million child deaths, accounting for nearly 12% of all under-five mortality worldwide. Many evidence-based interventions can reduce diarrhea mortality, including oral rehydration solution (ORS, zinc, and improved sanitation. Yet global coverage levels of such interventions remain low. A new scorecard of diarrhea control, showing how different countries are performing in their control efforts, could draw greater attention to the low coverage levels of proven interventions. METHODS: We conducted in-depth qualitative interviews with 21 experts, purposively sampled for their relevant academic or implementation expertise, to explore their views on (a the value of a scorecard of global diarrhea control and (b which indicators should be included in such a scorecard. We then conducted a ranking exercise in which we compiled a list of all 49 indicators suggested by the experts, sent the list to the 21 experts, and asked them to choose 10 indicators that they would include and 10 that they would exclude from such a scorecard. Finally, we created a "prototype" scorecard based on the 9 highest-ranked indicators. RESULTS: Key themes that emerged from coding the interview transcripts were: a scorecard could facilitate country comparisons; it could help to identify best practices, set priorities, and spur donor action; and it could help with goal-setting and accountability in diarrhea control. The nine highest ranking indicators, in descending order, were ORS coverage, rotavirus vaccine coverage, zinc coverage, diarrhea-specific mortality rate, diarrhea prevalence, proportion of population with access to improved sanitation, proportion with access to improved drinking water, exclusive breastfeeding coverage, and measles vaccine coverage. CONCLUSION: A new scorecard of global diarrhea control could help track progress, focus prevention and treatment efforts on the most effective interventions, establish transparency and

    The Lives Saved Tool (LiST) is a computer-based model that estimates the impact of scaling up key interventions to improve maternal, newborn and child health. Initially developed to inform the Lancet Child Survival Series of 2003, the functionality and scope of LiST have been expanded greatly over the past 10 years. This study sought to "take stock" of how LiST is now being used and for what purposes. We conducted a quantitative survey of LiST users, qualitative interviews with a smaller sample of LiST users and members of the LiST team at Johns Hopkins University, and a literature review of studies involving LiST analyses. LiST is being used by donors, international organizations, governments, NGOs and academic institutions to assist program evaluation, inform strategic planning and evidenced-based decision-making, and advocate for high-impact interventions. Some organizations have integrated LiST into internal workflows and built in-house capacity for using LiST, while other organizations rely on the LiST team for support and to outsource analyses. In addition to being a popular stand-alone software, LiST is used as a calculation engine for other applications. The Lives Saved Tool has been reported to be a useful model in maternal, newborn, and child health. With continued commitment, LiST should remain as a part of the international health toolkit used to assess maternal, newborn and child health programs.

    The GIOD (Globally Interconnected Object Databases) Project, a joint effort between Caltech and CERN, funded by Hewlett Packard Corporation, has investigated the use of WAN-distributed Object Databases and Mass Storage systems for LHC data. A prototype small- scale LHC data analysis center has been constructed using computing resources at Caltechs Centre for advanced Computing Research (CACR). These resources include a 256 CPU HP Exemplar of ~4600 SPECfp95, a 600 TByte High Performance Storage System (HPSS), and local/wide area links based on OC3 ATM. Using the exemplar, a large number of fully simulated CMS events were produced, and used to populate an object database with a complete schema for raw, reconstructed and analysis objects. The reconstruction software used for this task was based on early codes developed in preparation for the current CMS reconstruction program, ORCA. (6 refs).

The aims of the study were to describe the geographical distribution and assess the prevalence of anemia and malnutrition in children aged 5-10 years with GPS. This exploratory study was conducted over a period of 2 months in the rural field practice area of a medical college situated in Bangalore during June-July 2012. Children aged 5-10 years were the study subjects. GPS was used for describing the geographical distribution of anemia and nutrition status on the Google earth map. The prevalence of anemia in the study subjects was 8.7%. The prevalence of underweight, stunting, thinness, and severe thinness among the study subjects was 52.8%, 28.5%, 23.5%, and 29.1%, respectively; however, overweight and obesity were observed only in 0.9% and 1.2% of the study subjects, respectively. GPS was easy to use and was able to demonstrate the actual distribution of morbidity at the household level in the rural area.

    The South and West Francilien Pediatric Network (Réseau Pédiatrique du Sud et Ouest Francilien [RPSOF]) has established a protocol for the developmental follow up of infants inspired by the existing developmental scales adapted to the current practice of out patient consultation. The consultation described here collects a set of very simple objects and trade toys that are a support for a qualitative exploration of the development for the infants of less than 4 years of age. Different fields are taken into account: global motor skills, hand-eye coordination, manipulation and construction, communication and language, attentional capacity, relational and social behaviour. The time of exchange and play between the paediatrician and the infant allows a first detection of possible problems: the orientation towards a specialized professional for a consultation, a standard check-up or even a therapeutic care becomes easier and clearer. This playful environment also offers a space for the parents, and supports their participation as primary role players in the development of their child. This time, integral part of the consultation, is completed by the somatic examination and sensory screening tests. At present reserved for children identified as being at risk, this type of consultation could be universalised for all infants. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Full Text Available Abstract Background This paper describes the process used to develop an integrated set of culturally sensitive, evidence-based counselling tools (job aids by using qualitative participatory research. The aim of the intervention was to contribute to improving infant feeding counselling services for HIV positive women in the Kilimanjaro Region of Tanzania. Methods Formative research using a combination of qualitative methods preceded the development of the intervention and mapped existing practices, perceptions and attitudes towards HIV and infant feeding (HIV/IF among mothers, counsellors and community members. Intervention Mapping (IM protocol guided the development of the overall intervention strategy. Theories of behaviour change, a review of the international HIV/IF guidelines and formative research findings contributed to the definition of performance and learning objectives. Key communication messages and colourful graphic illustrations related to infant feeding in the context of HIV were then developed and/or adapted from existing generic materials. Draft materials were field tested with intended audiences and subjected to stakeholder technical review. Results An integrated set of infant feeding counselling tools, referred to as 'job aids', was developed and included brochures on feeding methods that were found to be socially and culturally acceptable, a Question and Answer Guide for counsellors, a counselling card on the risk of transmission of HIV, and an infant feeding toolbox for demonstration. Each brochure describes the steps to ensure safer infant feeding using simple language and images based on local ideas and resources. The brochures are meant to serve as both a reference material during infant feeding counselling in the ongoing prevention of mother to child transmission (pMTCT of HIV programme and as take home material for the mother. Conclusion The study underscores the importance of formative research and a systematic theory

    Bluefin tunas are one of the most important fishery resources worldwide. Because of high market values, bluefin tuna farming has been rapidly growing during recent years. At present, the most common form of the tuna farming is based on the stocking of wild-caught fish. Therefore, concerns have been raised about the negative impact of the tuna farming on wild stocks. Recently, the Pacific bluefin tuna (PBT), Thunnus orientalis, has succeeded in completing the reproduction cycle under aquaculture conditions, but production bottlenecks remain to be solved because of very little biological information on bluefin tunas. Functional genomics approaches promise to rapidly increase our knowledge on biological processes in the bluefin tuna. Here, we describe the development of the first 44K PBT oligonucleotide microarray (oligo-array), based on whole-genome shotgun (WGS) sequencing and large-scale expressed sequence tags (ESTs) data. In addition, we also introduce an initial 44K PBT oligo-array experiment using in vitro grown peripheral blood leukocytes (PBLs) stimulated with immunostimulants such as lipopolysaccharide (LPS: a cell wall component of Gram-negative bacteria) or polyinosinic:polycytidylic acid (poly I:C: a synthetic mimic of viral infection). This pilot 44K PBT oligo-array analysis successfully addressed distinct immune processes between LPS- and poly I:C- stimulated PBLs. Thus, we expect that this oligo-array will provide an excellent opportunity to analyze global gene expression profiles for a better understanding of diseases and stress, as well as for reproduction, development and influence of nutrition on tuna aquaculture production.

    In the last quarter of this century, global environmental problem has emerged as a major scientific, political and social issue. Specific Problems include: depletion of ozone layer by chlorofluorocarbons (CFCs), acid rain, destruction of tropical forests and desertification, pollution of the sea and global wanning due to the greenhouse effect by carbon dioxide and others. Among these problems, particular attention of the world has been focused on the global warming because it has direct linkage to energy consumption which our economic development depends on so far. On the other hand, the future program of The Sunshine Project for alternative energy technology R&D, The Moonlight Project for energy conservation technology R&D, and The Global Environmental Technology Program for environmental problem mitigating technology R&D which are Japan`s national projects being promoted by their Agency of Industrial Science and Technology (AIST) in the Ministry of International Trade and Industry have been reexamined in view of recent changes in the situations surrounding new energy technology. In this regard, The New Sunshine Program will be established by integrating these three activities to accelerate R&D in the field of energy and environmental technologies. In the reexamination, additional stress has been laid on the contribution to solving global environmental problem through development of clean renewable energies which constitute a major part of the {open_quotes}New Earth 21{close_quotes}, a comprehensive, long-term and international cooperative program proposed by MITI. The present paper discusses the results of feasibility study on hydrogen energy system leading to the concept of WE-NET following a brief summary on R&D status on solar and wind energy in Japan.

  13. Global safety

    2010-08-01

    Full Text Available Global Safety is a container concept referring to various threats such as HIV/Aids, floods and terrorism; threats with different causes and different effects. These dangers threaten people, the global economy and the slity of states. Policy making for this kind of threats often lack an overview of the real causes and the interventions are based on a too shallow analysis of the problem, mono-disciplinary and focus mostly only on the effects. It would be more appropriate to develop policy related to these issues by utilizing the approaches, methods and tools that have been developed for complex societal problems. Handling these complex societal problems should be done multidisciplinary instead of mono-disciplinary. In order to give politicians the opportunity to handle complex problems multidisciplinary, multidisciplinary research institutes should be created. These multidisciplinary research institutes would provide politicians with better approaches to handle this type of problem. In these institutes the knowledge necessary for the change of these problems can be created through the use of the Compram methodology which has been developed specifically for handling complex societal problems. In a six step approach, experts, actors and policymakers discuss the content of the problem and the possible changes. The framework method uses interviewing, the Group Decision Room, simulation models and scenario's in a cooperative way. The methodology emphasizes the exchange of knowledge and understanding by communication among and between the experts, actors and politicians meanwhile keeping emotion in mind. The Compram methodology will be further explained in relation to global safety in regard to terrorism, economy, health care and agriculture.

    To evaluate the effect of an individual health dialogue on health and risk factors for ischemic heart disease in addition to that of a community based strategy. Inhabitants in four communities in the area of Skaraborg, Sweden were invited to a health examination including a health dialogue both at the age of 30 and 35 (target communities). In another four communities inhabitants were invited only at the age of 35 (reference communities). Health and risk factors in 35-year old inhabitants in the target communities who participated in the health dialogue in 1989-1991 and 1994-1996 were analysed and compared with 35-year olds in the reference communities participating during the same periods of time. Inhabitants in communities where there had been a previous individualised health intervention programme had, on the community level, a more favourable development concerning dietary habits, mental stress, body mass index, waist circumference, cholesterol, blood pressure and metabolic risk profile compared to inhabitants in communities with only a community based health intervention programme. An individual lifestyle oriented health dialogue supported by a global health and risk assessment pedagogic tool seems to be more effective than a community health strategy only.

    A number of Department of Energy (DOE) science applications, involving exascale computing systems and large experimental facilities, are expected to generate large volumes of data, in the range of petabytes to exabytes, which will be transported over wide-area networks for the purpose of storage, visualization, and analysis. The objectives of this proposal are to (1) develop and test the component technologies and their synthesis methods to achieve source-to-sink high-performance flows, and (2) develop tools that provide these capabilities through simple interfaces to users and applications. In terms of the former, we propose to develop (1) optimization methods that align and transition multiple storage flows to multiple network flows on multicore, multibus hosts; and (2) edge and long-haul network path realization and maintenance using advanced provisioning methods including OSCARS and OpenFlow. We also propose synthesis methods that combine these individual technologies to compose high-performance flows using a collection of constituent storage-network flows, and realize them across the storage and local network connections as well as long-haul connections. We propose to develop automated user tools that profile the hosts, storage systems, and network connections; compose the source-to-sink complex flows; and set up and maintain the needed network connections.

    In the last two decades, simulation tools made a significant contribution to the great progress in development of power electronics. Time to market was shortened and development costs were reduced drastically. Falling costs, as well as improved speed and precision, opened new fields of application. Today, continuous and switched circuits can be mixed. A comfortable number of powerful simulation tools is available. The users have to choose the best suitable for their application. Here a simple rule applies: The best available simulation tool is the tool the user is already used to (provided, it can solve the task). Abilities, speed, user friendliness and other features are continuously being improved—even though they are already powerful and comfortable. This paper aims at giving the reader an insight into the simulation of power electronics. Starting with a short description of the fundamentals of a simulation tool as well as properties of tools, several tools are presented. Starting with simplified models ...

    Full Text Available The objective of the audit is to determine the prevalence of malnutrition in maintenance peritoneal dialysis (MPD patients in the Top End of the Northern Territory, using the modified Subjective Global Assessment (SGA tool. Methods: The audit was conducted in an outpatients setting. Approximately 75% of PD patients in the Top End Renal service are represented by Aboriginal and Torres Strait Island people. The study population was MPD patients in the Top End Renal Service (TERS of the Northern Territory, from January 1st 2010 to December 31st 2010. Results were compared to malnutrition rates found in the 2008/09 the audit of MPD patients in the TERS. The SGA’s were performed by the renal Dietitian as part of the standard dietetic support of MPD patients. SGA scores were collected from patient medical charts. Results: Patients were classified into one of three categories, based on their SGA score (A Well-nourished; (B Mild- Moderate Malnutrition, (C Severe malnutrition. Malnutrition (B or C was detected in 10% of PD patients, compared to the 2008/09 audit where 76% of MPD patients had some degree of malnutrition. Summary: These results were much lower than malnutrition rates (76% in the MPD patients audited in 2008/09. A number of factors affecting the PD service after the 2008/09 audit could explain the decrease in malnutrition rates including the implementation of free oral nutrition supplements to MPD patients, development of service wide culturally appropriate education resources used in the pre-dialysis and dialysis stage. Future research into the correlation between improved peritonitis rates and decreased malnutrition rates in the population are warranted.

    The administration of You Gui Wan (YGW) decoction has been observed to improve vaginal atrophy induced by ovariectomy (OVX) in rats. The aim of the current study was to explore the possible mechanisms underlying this effect. Following OVX, 37 Sprague Dawley female rats were randomly divided into three groups which were orally administered with YGW decoction, saline or estrogen for 11 weeks. In parallel with this, 19 normal and 17 rats with sham-surgery were used as controls. The effects of these treatments on estrogen receptors (ER) and various angiogenic factors, including vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor-1 (VEGFR-1), angiopoietin (Ang)1 and 2 and basic fibroblast growth factor (bFGF) in the vagina were compared using immunohistochemistry or quantitative polymerase chain reaction (qPCR). OVX was found to induce significant vaginal atrophy and decrease the expression of ER and various angiogenic factors when compared with the normal and sham-surgery animals (all P<0.05). Estrogen replacement and the administration of YGW decoction reversed the vaginal atrophic process. The hormonal replacement and YGW treatment recovered the protein expression of ER-α and -β, VEGF and VEGFR-1 and the mRNA levels of ER-α, VEGF, VEGFR-1, Ang1 and 2, and bFGF when compared with OVX-rats with saline, normal and sham-surgery treatments (all P<0.05). Thus, it may be concluded that a possible mechanism underlying the effect of YGW on OVX-induced vaginal atrophy may be the upregulated expression of ER and various angiogenic factors in the vaginal tissue.

    Soil organic carbon (SOC) is a significant component of the global carbon (C) cycle. Changes in SOC storage affect atmospheric CO2 concentrations on decadal to centennial timescales. The C-TOOL model was developed to simulate farm- and regional-scale effects of management on medium- to long......-term SOC storage in the profile of well-drained agricultural mineral soils. C-TOOL uses three SOC pools for both the topsoil (0–25 cm) and the subsoil (25–100 cm), and applies temperature-dependent first order kinetics to regulate C turnover. C-TOOL also enables the simulation of 14C turnover. The simple...... model structure facilitates calibration and requires few inputs (mean monthly air temperature, soil clay content, soil C/N ratio and C in organic inputs).

    2006-07-01

    In recent years, modeling and simulation has played an increasingly important role in the maintenance of the nuclear stockpile. The Advanced Simulation and Computing (ASC) program continues to support and encourage the development of a modeling and simulation infrastructure to make these goals a reality. The Distance Computing Network has been making make the ASC resources available to users throughout the tri-lab environment for over five years. This network relies on the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite to provide high performance and reliable communications. Understanding TCP/IP operation in this unique environment is critical. Software modeling has been used to analyze current network performance and predict the effect of proposed changes. Recently the network architecture was radically changed and the software model had to be changed as well. Whereas the original network was based on 2.5 gigabit per second ATM links, the redesigned network is comprised of 10-gigabit Ethernet links arranged as a 3-node ring. Therefore, a new software model was needed to continue to predict the performance of proposed changes and allow engineers to experiment with new network applications without the risk of interfering with critical operations.

    In order to facilitate Earth science data access, the NASA Goddard Earth Sciences Data Information Services Center (GES DISC) has developed a web prototype, the Hurricane Data Analysis Tool (HDAT; URL: http://disc.gsfc.nasa.gov/HDAT), to allow users to conduct online visualization and analysis of several remote sensing and model datasets for educational activities and studies of tropical cyclones and other weather phenomena. With a web browser and few mouse clicks, users can have a full access to terabytes of data and generate 2-D or time-series plots and animation without downloading any software and data. HDAT includes data from the NASA Tropical Rainfall Measuring Mission (TRMM), the NASA Quick Scatterometer(QuikSCAT) and NECP Reanalysis, and the NCEP/CPC half-hourly, 4-km Global (60 N - 60 S) IR Dataset. The GES DISC archives TRMM data. The daily global rainfall product derived from the 3-hourly multi-satellite precipitation product (3B42 V6) is available in HDAT. The TRMM Microwave Imager (TMI) sea surface temperature from the Remote Sensing Systems is in HDAT as well. The NASA QuikSCAT ocean surface wind and the NCEP Reanalysis provide ocean surface and atmospheric conditions, respectively. The global merged IR product, also known as, the NCEP/CPC half-hourly, 4-km Global (60 N -60 S) IR Dataset, is one of TRMM ancillary datasets. They are globally-merged pixel-resolution IR brightness temperature data (equivalent blackbody temperatures), merged from all available geostationary satellites (GOES-8/10, METEOSAT-7/5 & GMS). The GES DISC has collected over 10 years of the data beginning from February of 2000. This high temporal resolution (every 30 minutes) dataset not only provides additional background information to TRMM and other satellite missions, but also allows observing a wide range of meteorological phenomena from space, such as, hurricanes, typhoons, tropical cyclones, mesoscale convection system, etc. Basic functions include selection of area of

    Decision support tools have been demonstrated to improve adherence to medical guidelines; however, smartphone applications (apps) have not been studied in this regard. In a collaboration between Vanderbilt University and the American Society of Regional Anesthesia and Pain Medicine (ASRA), the ASRA Coags Regional app was created to be a decision support tool for the 2010 published guideline on regional anesthesia for patients receiving anticoagulation. This is a review of the distribution and usage of this app. The app was created to be a user-friendly version of the guideline. Download statistics were collected from April 2014 to October 2015, and app usage data were collected from October 2014 to October 2015. Usage data were analyzed for number of devices, number of search sessions, medications searched, and types of procedures. There were 8381 downloads, with 83% from North America. Of users who allowed data tracking, 4504 unique devices were identified with 30,003 separate search events. The most searched-for medications were rivaroxaban (n = 4427; 11%), clopidogrel (n = 4042; 10%), and enoxaparin, prophylactic twice daily dosing (n = 3249; 8%). Neuraxial procedures (n = 22,477; 78%) were the most commonly searched-for procedures and over half (n = 22,773; 52%) the users were interested in how long to hold a medication before performing a procedure. This is the first publication of download and usage data concerning medical smartphone apps. It provides a template for future app uptake and use in clinical practice. The app platform provides a new mechanism of rapidly disseminating guidelines and facilitating distribution of frequent updates.

This current study compared the use of a GRS and a checklist as formal rating instruments to evaluate CRM performance during simulated emergencies. First-year and third-year residents participated in two simulator scenarios each. Three raters then evaluated resident performance in CRM using edited video recordings using both a GRS and a checklist. The Ottawa GRS provides a seven-point anchored ordinal scale for performance in five categories of CRM, and an overall performance score. The Ottawa CRM checklist provides 12 items in the five categories of CRM, with a maximum cumulative score of 30 points. Construct validity was measured on the basis of content validity, response process, internal structure, and response to other variables. T-test analysis of Ottawa GRS scores was conducted to examine response to the variable of level of training. Intraclass correlation coefficient (ICC) scores were used to measure inter-rater reliability for both scenarios. Thirty-two first-year and 28 third-year residents participated in the study. Third-year residents produced higher mean scores for overall CRM performance than first-year residents (P CRM checklist (P CRM checklist. Users indicated a strong preference for the Ottawa GRS given ease of scoring, presence of an overall score, and the potential for formative evaluation. Construct validity seems to be present when using both the Ottawa GRS and CRM checklist to evaluate CRM performance during simulated emergencies. Data also indicate the presence of moderate inter-rater reliability when using both the Ottawa GRS and CRM checklist.

  18. Global Geomorphology

    Any global view of landforms must include an evaluation of the link between plate tectonics and geomorphology. To explain the broad features of the continents and ocean floors, a basic distinction between the tectogene and cratogene part of the Earth's surface must be made. The tectogene areas are those that are dominated by crustal movements, earthquakes and volcanicity at the present time and are essentially those of the great mountain belts and mid ocean ridges. Cratogene areas comprise the plate interiors, especially the old lands of Gondwanaland and Laurasia. Fundamental as this division between plate margin areas and plate interiors is, it cannot be said to be a simple case of a distinction between tectonically active and stable areas. Indeed, in terms of megageomorphology, former plate margins and tectonic activity up to 600 million years ago have to be considered.

    Competition among multinationals these days is likely to be a three-dimensional game of global chess: The moves an organization makes in one market are designed to achieve goals in another in ways that aren't immediately apparent to its rivals. The authors--all management professors-call this approach "competing under strategic interdependence," or CSI. And where this interdependence exists, the complexity of the situation can quickly overwhelm ordinary analysis. Indeed, most business strategists are terrible at anticipating the consequences of interdependent choices, and they're even worse at using interdependency to their advantage. In this article, the authors offer a process for mapping the competitive landscape and anticipating how your company's moves in one market can influence its competitive interactions in others. They outline the six types of CSI campaigns--onslaughts, contests, guerrilla campaigns, feints, gambits, and harvesting--available to any multiproduct or multimarket corporation that wants to compete skillfully. They cite real-world examples such as the U.S. pricing battle Philip Morris waged with R.J. Reynolds--not to gain market share in the domestic cigarette market but to divert R.J. Reynolds's resources and attention from the opportunities Philip Morris was pursuing in Eastern Europe. And, using data they collected from their studies of consumer-products companies Procter & Gamble and Unilever, the authors describe how to create CSI tables and bubble charts that present a graphical look at the competitive landscape and that may uncover previously hidden opportunities. The CSI mapping process isn't just for global corporations, the authors explain. Smaller organizations that compete with a portfolio of products in just one national or regional market may find it just as useful for planning their next business moves.

  20. Quantum topology and global anomalies

    1996-01-01

    Anomalies are ubiquitous features in quantum field theories. They can ruin the consistency of such theories and put significant restrictions on their viability, especially in dimensions higher than four. Global gauge and gravitational anomalies are to date, one of the scant powerful and probing tools available to physicists in the pursuit of uniqueness.This monograph is one of the very few that specializes in the study of global anomalies in quantum field theories. A discussion of various issues associated to three dimensional physics - the Chern-Simons-Witten theories - widen the scope of thi

  1. Expanding the population coverage of evidence-based interventions with community health workers to save the lives of mothers and children: an analysis of potential global impact using the Lives Saved Tool (LiST).

    Evidence has been accumulating that community health workers (CHWs) providing evidence-based interventions as part of community-based primary health care (CBPHC) can lead to reductions in maternal, neonatal and child mortality. However, investments to strengthen and scale-up CHW programs still remain modest. We used the Lives Saved Tool (LiST) to estimate the number of maternal, neonatal and child deaths and stillbirths that could be prevented if 73 countries effectively scaled up the population coverage of 30 evidence-based interventions that CHWs can deliver in these high-burden countries. We set population coverage targets at 50%, 70%, and 90% and summed the country-level results by region and by all 73 high-burden countries combined. We also estimated which specific interventions would save the most lives. LiST estimates that a total of 3.0 (sensitivity bounds 1.8-4.0), 4.9 (3.1-6.3) and 6.9 (3.7-8.7) million deaths would be prevented between 2016 and 2020 if CBPHC is gradually scaled up during this period and if coverage of key interventions reaches 50%, 70%, and 90% respectively. There would be 14%, 23%, and 32% fewer deaths in the final year compared to a scenario assuming no intervention coverage scale up. The Africa Region would receive the most benefit by far: 58% of the lives saved at 90% coverage would be in this region. The interventions contributing the greatest impact are nutritional interventions during pregnancy, treatment of malaria with artemisinin compounds, oral rehydration solution for childhood diarrhea, hand washing with soap, and oral antibiotics for pneumonia. Scaling up CHW programming to increase population-level coverage of life-saving interventions represents a very promising strategy to achieve universal health coverage and end preventable maternal and child deaths by 2030. Numerous practical challenges must be overcome, but there is no better alternative at present. Expanding the coverage of key interventions for maternal nutrition

    Risk management is a fundamental component of any successful company, whether it is in economic, societal or environmental aspect. Risk management is an especially important activity for companies that optimal security challenge of products and services is great. This is the case especially for the health sector institutions. Risk management is therefore a decision support tool and a means to ensure the sustainability of an organization. In this context, what methods and approaches implemented to manage the risks? Through this state of the art, we are interested in the concept of risk and risk management processes. Then we focus on the different methods of risk management and the criteria for choosing among these methods. Finally we highlight the need to supplement these methods by a systemic and global approach including through risk assessment by the audits. Copyright © 2015 Elsevier Masson SAS.

    Full Text Available Abstract: Despite the changes, the configuration of global and regional power centers can still be represented as an hierarchy in which the first among equals, the equal, the peripheral and the marginal centers coexist with each other. BRICS’ as the means for increasing adaptivity to global realities and influencing global and regional process can potentially contribute to the shaping of multipolarity. The article suggests that BRICS is the most prospective project for coordinating of actions of various power centers of the world, as this format combines the political will, the economic foundation and the use of soft power tools. A Greater Europe continues to be the priority region for Russia in a political, economic, financial and cultural sense, and due to its geographical and civilizational particularity Russia can act as the link between other world major players both within BRICS and Russia-BRICS-EU triangle.

    Over 600 million people live close enough to active volcanoes to be affected when they erupt. Volcanic eruptions cause loss of life, significant economic losses and severe disruption to people's lives, as highlighted by the recent eruption of Mount Merapi in Indonesia. The eruption of Eyjafjallajökull, Iceland in 2010 illustrated the potential of even small eruptions to have major impact on the modern world through disruption of complex critical infrastructure and business. The effects in the developing world on economic growth and development can be severe. There is evidence that large eruptions can cause a change in the earth's climate for several years afterwards. Aside from meteor impact and possibly an extreme solar event, very large magnitude explosive volcanic eruptions may be the only natural hazard that could cause a global catastrophe. GVM is a growing international collaboration that aims to create a sustainable, accessible information platform on volcanic hazard and risk. We are designing and developing an integrated database system of volcanic hazards, vulnerability and exposure with internationally agreed metadata standards. GVM will establish methodologies for analysis of the data (eg vulnerability indices) to inform risk assessment, develop complementary hazards models and create relevant hazards and risk assessment tools. GVM will develop the capability to anticipate future volcanism and its consequences. NERC is funding the start-up of this initiative for three years from November 2011. GVM builds directly on the VOGRIPA project started as part of the GRIP (Global Risk Identification Programme) in 2004 under the auspices of the World Bank and UN. Major international initiatives and partners such as the Smithsonian Institution - Global Volcanism Program, State University of New York at Buffalo - VHub, Earth Observatory of Singapore - WOVOdat and many others underpin GVM.

  8. 10 rules for managing global innovation.

    Science.gov (United States)

    Wilson, Keeley; Doz, Yves L

    2012-10-01

    More and more companies recognize that their dispersed, global operations are a treasure trove of ideas and capabilities for innovation. But it's proving harder than expected to unearth those ideas or exploit those capabilities. Part of the problem is that companies manage global innovation the same way they manage traditional, single-location projects. Single-location projects draw on a large reservoir of tacit knowledge, shared context, and trust that global projects lack. The management challenge, therefore, is to replicate the positive aspects of colocation while harnessing the opportunities of dispersion. In this article, Insead's Wilson and Doz draw on research into global strategy and innovation to present a set of guidelines for setting up and managing global innovation. They explore in detail the challenges that make global projects inherently different and show how these can be overcome by applying superior project management skills across teams, fostering a strong collaborative culture, and using a robust array of communications tools.

    Full Text Available Apesar da ampla adoção pelas organizações de sistemas e modelos de gestão da qualidade mundialmente reconhecidos, pouca atenção ainda tem sido dada às práticas de comunicação interna que podem contribuir para a promoção da qualidade. Para se tornarem comprometidos com a entrega de produtos e serviços de qualidade, os membros de uma organização precisam receber informações, que lhes permitam entender e aceitar seus papéis individuais e coletivos nesse processo, exigindo, portanto, comunicação. O artigo busca a compreensão de como a comunicação interna pode ser utilizada como um instrumento de promoção da qualidade. A pesquisa foi conduzida pelo método estudo de caso, contando com a contribuição de uma empresa global de comunicação. Os resultados alcançados permitiram a identificação e a proposição de um conjunto de fatores a serem considerados pelas organizações como determinantes para a efetiva utilização da comunicação interna como um instrumento de promoção da qualidade, com destaque para: segmentação do público interno; coerência da linguagem; utilização estratégica de recursos visuais; comunicação de resultados; desenvolvimento de uma cultura da qualidade e compreensão da comunicação interna sob uma abordagem processual.Despite the wide adoption of quality management systems and standards recognized all over the world by organizations, little attention has been given to internal communication practices which may contribute to an organization-s quality promotion.

    2017-04-01

    The large tsunami disasters of the last two decades have highlighted the need for a thorough understanding of the risk posed by relatively infrequent but disastrous tsunamis and the importance of a comprehensive and consistent methodology for quantifying the hazard. In the last few years, several methods for probabilistic tsunami hazard analysis have been developed and applied to different parts of the world. In an effort to coordinate and streamline these activities and make progress towards implementing the Sendai Framework of Disaster Risk Reduction (SFDRR) we have initiated a Global Tsunami Model (GTM) working group with the aim of i) enhancing our understanding of tsunami hazard and risk on a global scale and developing standards and guidelines for it, ii) providing a portfolio of validated tools for probabilistic tsunami hazard and risk assessment at a range of scales, and iii) developing a global tsunami hazard reference model. This GTM initiative has grown out of the tsunami component of the Global Assessment of Risk (GAR15), which has resulted in an initial global model of probabilistic tsunami hazard and risk. Started as an informal gathering of scientists interested in advancing tsunami hazard analysis, the GTM is currently in the process of being formalized through letters of interest from participating institutions. The initiative has now been endorsed by the United Nations International Strategy for Disaster Reduction (UNISDR) and the World Bank's Global Facility for Disaster Reduction and Recovery (GFDRR). We will provide an update on the state of the project and the overall technical framework, and discuss the technical issues that are currently being addressed, including earthquake source recurrence models, the use of aleatory variability and epistemic uncertainty, and preliminary results for a probabilistic global hazard assessment, which is an update of the model included in UNISDR GAR15.

The communication among countries and not only them, has been increased expanding political ties, making possible greater economic integration and wider cultural relations combined with augmented global wealth across the world. But, the process of globalization is in wider terms considered a beneficial one, but also viewed by some countries as a menace to national sovereignty and national culture. This paper tries to explain the obstacles to the process of globalization and its attendant benefits. Although globalization has arisen as a result of a more stable world, the factors that had contributed to its rise also help the factions interested to bring destabilization. In an academic approach in this article, between the research and comparative methods, I have been trying to get the maxims between economy, politics and diplomacy in their efforts of affecting the global era.

    Recently, a Global Flood Model (GFM) initiative has been proposed by Willis, UK Met Office, Esri, Deltares and IBM. The idea is to create a global community platform that enables better understanding of the complexities of flood risk assessment to better support the decisions, education and communication needed to mitigate flood risk. The GFM will provide tools for assessing the risk of floods, for devising mitigation strategies such as land-use changes and infrastructure improvements, and for enabling effective pre- and post-flood event response. The GFM combines humanitarian and commercial motives. It will benefit: - The public, seeking to preserve personal safety and property; - State and local governments, seeking to safeguard economic activity, and improve resilience; - NGOs, similarly seeking to respond proactively to flood events; - The insurance sector, seeking to understand and price flood risk; - Large corporations, seeking to protect global operations and supply chains. The GFM is an integrated and transparent set of modules, each composed of models and data. For each module, there are two core elements: a live "reference version" (a worked example) and a framework of specifications, which will allow development of alternative versions. In the future, users will be able to work with the reference version or substitute their own models and data. If these meet the specification for the relevant module, they will interoperate with the rest of the GFM. Some "crowd-sourced" modules could even be accredited and published to the wider GFM community. Our intent is to build on existing public, private and academic work, improve local adoption, and stimulate the development of multiple - but compatible - alternatives, so strengthening mankind's ability to manage flood impacts. The GFM is being developed and managed by a non-profit organization created for the purpose. The business model will be inspired from open source software (eg Linux): - for non-profit usage

  16. Lightening Global Types

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Global session types prevent participants from waiting for never coming messages. Some interactions take place just for the purpose of informing receivers that some message will never arrive or the session is terminated. By decomposing a big global type into several light global types, one can avoid such kind of redundant interactions. Lightening global types gives us cleaner global types, which keep all necessary communications. This work proposes a framework which allows to easily decompose global types into light global types, preserving the interaction sequences of the original ones but for redundant interactions.

  6. GEM - The Global Earthquake Model

    Science.gov (United States)

    Smolka, A.

    2009-04-01

    Over 500,000 people died in the last decade due to earthquakes and tsunamis, mostly in the developing world, where the risk is increasing due to rapid population growth. In many seismic regions, no hazard and risk models exist, and even where models do exist, they are intelligible only by experts, or available only for commercial purposes. The Global Earthquake Model (GEM) answers the need for an openly accessible risk management tool. GEM is an internationally sanctioned public private partnership initiated by the Organisation for Economic Cooperation and Development (OECD) which will establish an authoritative standard for calculating and communicating earthquake hazard and risk, and will be designed to serve as the critical instrument to support decisions and actions that reduce earthquake losses worldwide. GEM will integrate developments on the forefront of scientific and engineering knowledge of earthquakes, at global, regional and local scale. The work is organized in three modules: hazard, risk, and socio-economic impact. The hazard module calculates probabilities of earthquake occurrence and resulting shaking at any given location. The risk module calculates fatalities, injuries, and damage based on expected shaking, building vulnerability, and the distribution of population and of exposed values and facilities. The socio-economic impact module delivers tools for making educated decisions to mitigate and manage risk. GEM will be a versatile online tool, with open source code and a map-based graphical interface. The underlying data will be open wherever possible, and its modular input and output will be adapted to multiple user groups: scientists and engineers, risk managers and decision makers in the public and private sectors, and the public-at- large. GEM will be the first global model for seismic risk assessment at a national and regional scale, and aims to achieve broad scientific participation and independence. Its development will occur in a

    2015-09-01

    Full Text Available ABSTRACTThe gathering momentum of globalization in the world economy has coincided with the spread of political democracy across countries. Economies have become global. But politics remains national. This essay explores the relationship between globalization and democracy, which is neither linear nor characterized by structural rigidities. It seeks to analyze how globalization might constrain degrees of freedom for nation states and space for democratic politics, and how political democracy within countries might exercise some checks and balances on markets and globalization. The essential argument is that the relationship between globalization and democracy is dialectical and does not conform to ideological caricatures.

    A variety of shifts emergent with globalization, which are reflected in part by nascent programs in "Global Public Health," "Global Health Sciences," and "Global Health," are redefining international public health. We explore three of these shifts as a critical discourse and intervention in global health diplomacy: the expansion in non-governmental organization participation in international health programs, the globalization of science and pharmaceutical research, and the use of militarized languages of biosecurity to recast public health programs. Using contemporary anthropological and international health literature, we offer a critical yet hopeful exploration of the implications of these shifts for critical inquiry, health, and the health professions.

  11. Monitoring Global Croplands with Coarse Resolution Earth Observations: The Global Agriculture Monitoring (GLAM Project

    Directory of Open Access Journals (Sweden)

    Inbal Becker-Reshef

    2010-06-01

    Full Text Available In recent years there has been a dramatic increase in the demand for timely, comprehensive global agricultural intelligence. Timely information on global crop production is indispensable for combating the growing stress on the world’s crop production and for securing both short-term and long-term stable and reliable supply of food. Global agriculture monitoring systems are critical to providing this kind of intelligence and global earth observations are an essential component of an effective global agricultural monitoring system as they offer timely, objective, global information on croplands distribution, crop development and conditions as the growing season progresses. The Global Agriculture Monitoring Project (GLAM, a joint NASA, USDA, UMD and SDSU initiative, has built a global agricultural monitoring system that provides the USDA Foreign Agricultural Service (FAS with timely, easily accessible, scientifically-validated remotely-sensed data and derived products as well as data analysis tools, for crop-condition monitoring and production assessment. This system is an integral component of the USDA’s FAS Decision Support System (DSS for agriculture. It has significantly improved the FAS crop analysts’ ability to monitor crop conditions, and to quantitatively forecast crop yields through the provision of timely, high-quality global earth observations data in a format customized for FAS alongside a suite of data analysis tools. FAS crop analysts use these satellite data in a ‘convergence of evidence’ approach with meteorological data, field reports, crop models, attaché reports and local reports. The USDA FAS is currently the only operational provider of timely, objective crop production forecasts at the global scale. These forecasts are routinely used by the other US Federal government agencies as well as by commodity trading companies, farmers, relief agencies and foreign governments. This paper discusses the operational components

  20. Security Components of Globalization

    Directory of Open Access Journals (Sweden)

    Florin Iftode

    2015-05-01

    Full Text Available The objective of this paper is our intention to present what are the main connections between globalization and international security. In terms of global security we can perceive the globalization as a process by which global state is represented by the UN, with a single world system, represented by major security organizations and with global effects. We will present from the beginning the main theoretical aspects that define the phenomenon of globalization, and then our contribution in assessing the implications of this phenomenon on the regional and global security. The results of our research are materialized in the last part of the paper. They emphasize the personal assessments on how the phenomenon of globalization has direct effect on global security. When talking about government, we think of norms, rules and decisionmaking procedures in the management of international life. The value that we add to the new scientific interpretation of the definition of globalization is represented, primarily, by the valuable bibliographic used resources and the original approach on the concept that refers to the links between globalization and security. This article may be, at any time, a starting point in an interesting research direction in the field of global security.

  11. Open Health Tools: Tooling for Interoperable Healthcare

    Directory of Open Access Journals (Sweden)

    Skip McGaughey

    2008-11-01

    Full Text Available The Open Health Tools initiative is creating an ecosystem focused on the production of software tooling that promotes the exchange of medical information across political, geographic, cultural, product, and technology lines. At its core, OHT believes that the availability of high-quality tooling that interoperates will propel the industry forward, enabling organizations and vendors to build products and systems that effectively work together. This will ?raise the interoperability bar? as a result of having tools that just work. To achieve these lofty goals, careful consideration must be made to the constituencies that will be most affected by an OHT-influenced world. This document outlines a vision of OHT?s impact to these stakeholders. It does not explain the OHT process itself or how the OHT community operates. Instead, we place emphasis on the impact of that process within the health industry. The catchphrase ?code is king? underpins this document, meaning that the manifestation of any open source community lies in the products and technology it produces.

  12. Global temperatures and the global warming ``debate''

    Science.gov (United States)

    Aubrecht, Gordon

    2009-04-01

    Many ordinary citizens listen to pronouncements on talk radio casting doubt on anthropogenic global warming. Some op-ed columnists likewise cast doubts, and are read by credulous citizens. For example, on 8 March 2009, the Boston Globe published a column by Jeff Jacoby, ``Where's global warming?'' According to Jacoby, ``But it isn't such hints of a planetary warming trend that have been piling up in profusion lately. Just the opposite.'' He goes on to write, ``the science of climate change is not nearly as important as the religion of climate change,'' and blamed Al Gore for getting his mistaken views accepted. George Will at the Washington Post also expressed denial. As a result, 44% of U.S. voters, according to the January 19 2009 Rasmussen Report, blame long-term planetary trends for global warming, not human beings. Is there global cooling, as skeptics claim? We examine the temperature record.

    2011-01-01

    Although the resources and knowledge for achieving improved global health exist, a new, critical paradigm on health as an aspect of human development, human security, and human rights is needed. Such a shift is required to sufficiently modify and credibly reduce the present dominance of perverse market forces on global health. New scientific discoveries can make wide-ranging contributions to improved health; however, improved global health depends on achieving greater social justice, economic redistribution, and enhanced democratization of production, caring social institutions for essential health care, education, and other public goods. As with the quest for an HIV vaccine, the challenge of improved global health requires an ambitious multidisciplinary research program. PMID:21330597

  14. Global Elite as Transnational Capitalist Class

    Directory of Open Access Journals (Sweden)

    Lukáš Kantor

    2017-01-01

    Full Text Available As a contribution to the burgeoning field of multidisciplinary globalization studies, this article evaluates how IR grand theories can conceptualize the phenomenon of global elite. It compares and synthesizes (neoliberalism, constructivism, feminism and neo-Marxism. Liberal approaches use the analytical tool of transnational actors or transnational networks. In constructivist’s perspective, part of global elite falls into the category of epistemic community. Feminists offer the term Davos Men. Neo-Marxist conceptualization revolves around the notion of transnational capitalist class. The paper concludes that neo-Marxist IR theory best accounts for the global elite and therefore, the debates on the transnational capitalist class are thoroughly and critically reviewed.

    This paper employs a panel data set to estimate the effect of globalization on four measures of economic freedom. Contrary to previous studies, the paper distinguishes between three separate types of globalization: economic, social and political. It also separates effects for poor and rich...... countries, and autocracies and democracies. The results show that economic globalization is negatively associated with government size and positively with regulatory freedom in rich countries; social globalization is positively associated with legal quality in autocracies and with the access to sound money...... in democracies.

    2016-04-01

    Global Collaborative STEM Education, as the name suggests, simultaneously supports two sets of knowledge and skills. The first set is STEM -- science, technology, engineering and math. The other set of content knowledge and skills is that of global collaboration. Successful global partnerships require awareness of one's own culture, the biases embedded within that culture, as well as developing awareness of the collaborators' culture. Workforce skills fostered include open-mindedness, perseverance when faced with obstacles, and resourceful use of technological "bridges" to facilitate and sustain communication. In respect for the 2016 GIFT Workshop focus, Global Collaborative STEM Education projects dedicated to astronomy research will be presented. The projects represent different benchmarks within the Global Collaborative STEM Education continuum, culminating in an astronomy research experience that fully reflects how the global STEM workforce collaborates. To facilitate wider engagement in Global Collaborative STEM Education, project summaries, classroom resources and contact information for established international collaborative astronomy research projects will be disseminated.

    Gozard, Patrick; Bret, Emmanuel; Cathala, Thierry

    2008-04-01

    To perform multi-sensors simulations, the French DGA/DET (Directorate for Technical Evaluation of the French Ministry of Defense) uses CHORALE (simulated Optronic Acoustic Radar battlefield). CHORALE enables the user to create virtual and realistic multi spectral 3D scenes, and generates the physical signal received by one or several sensors, typically an IR sensor or an acoustic sensor. This article presents different kinds of scenario such as desert, urban, campaign place to evaluate intelligent artillery ammunition. The ammunition described has to detect thermal contrast above a target area for the detection capability and firing decision. The scene is as realistic as possible to give to french army good parameters according to their request in a typical operational scenario. That includes background with trees, houses, roads, fields, targets, dunes, with different materials such as grass, sand, rock, wood, concrete... All object in the 3D scene is characterized by optronic parameters used by CHORALE Workbench. The signal provided by this workbench is adapted by AMOCO workbench which allows defining sensor technology. Then a process unit provides the firing decision and the lethality data from the target which has been reached. Each tool is explained to understand the physics phenomena in the scene to take into account atmospheric transmission, radiative parameters of objects and counter-measure devices. Finally, this paper shows results by coupling the operational scenario with sensor model to do a global simulation in order to determine global performances of artillery ammunition.

  12. Global solidarity, migration and global health inequity.

    Science.gov (United States)

    Eckenwiler, Lisa; Straehle, Christine; Chung, Ryoa

    2012-09-01

    The grounds for global solidarity have been theorized and conceptualized in recent years, and many have argued that we need a global concept of solidarity. But the question remains: what can motivate efforts of the international community and nation-states? Our focus is the grounding of solidarity with respect to global inequities in health. We explore what considerations could motivate acts of global solidarity in the specific context of health migration, and sketch briefly what form this kind of solidarity could take. First, we argue that the only plausible conceptualization of persons highlights their interdependence. We draw upon a conception of persons as 'ecological subjects' and from there illustrate what such a conception implies with the example of nurses migrating from low and middle-income countries to more affluent ones. Next, we address potential critics who might counter any such understanding of current international politics with a reference to real-politik and the insights of realist international political theory. We argue that national governments--while not always or even often motivated by moral reasons alone--may nevertheless be motivated to acts of global solidarity by prudential arguments. Solidarity then need not be, as many argue, a function of charitable inclination, or emergent from an acknowledgment of injustice suffered, but may in fact serve national and transnational interests. We conclude on a positive note: global solidarity may be conceptualized to helpfully address global health inequity, to the extent that personal and transnational interdependence are enough to motivate national governments into action. © 2012 Blackwell Publishing Ltd.

  2. Global warming without global mean precipitation increase?

    Science.gov (United States)

    Salzmann, Marc

    2016-06-01

    Global climate models simulate a robust increase of global mean precipitation of about 1.5 to 2% per kelvin surface warming in response to greenhouse gas (GHG) forcing. Here, it is shown that the sensitivity to aerosol cooling is robust as well, albeit roughly twice as large. This larger sensitivity is consistent with energy budget arguments. At the same time, it is still considerably lower than the 6.5 to 7% K(-1) decrease of the water vapor concentration with cooling from anthropogenic aerosol because the water vapor radiative feedback lowers the hydrological sensitivity to anthropogenic forcings. When GHG and aerosol forcings are combined, the climate models with a realistic 20th century warming indicate that the global mean precipitation increase due to GHG warming has, until recently, been completely masked by aerosol drying. This explains the apparent lack of sensitivity of the global mean precipitation to the net global warming recently found in observations. As the importance of GHG warming increases in the future, a clear signal will emerge.

  3. OOTW Force Design Tools

    Energy Technology Data Exchange (ETDEWEB)

    Bell, R.E.; Hartley, D.S.III; Packard, S.L.

    1999-05-01

    This report documents refined requirements for tools to aid the process of force design in Operations Other Than War (OOTWs). It recommends actions for the creation of one tool and work on other tools relating to mission planning. It also identifies the governmental agencies and commands with interests in each tool, from whom should come the user advisory groups overseeing the respective tool development activities. The understanding of OOTWs and their analytical support requirements has matured to the point where action can be taken in three areas: force design, collaborative analysis, and impact analysis. While the nature of the action and the length of time before complete results can be expected depends on the area, in each case the action should begin immediately. Force design for OOTWs is not a technically difficult process. Like force design for combat operations, it is a process of matching the capabilities of forces against the specified and implied tasks of the operation, considering the constraints of logistics, transport and force availabilities. However, there is a critical difference that restricts the usefulness of combat force design tools for OOTWs: the combat tools are built to infer non-combat capability requirements from combat capability requirements and cannot reverse the direction of the inference, as is required for OOTWs. Recently, OOTWs have played a larger role in force assessment, system effectiveness and tradeoff analysis, and concept and doctrine development and analysis. In the first Quadrennial Defense Review (QDR), each of the Services created its own OOTW force design tool. Unfortunately, the tools address different parts of the problem and do not coordinate the use of competing capabilities. These tools satisfied the immediate requirements of the QDR, but do not provide a long-term cost-effective solution.

  4. Forms of global governence

    Directory of Open Access Journals (Sweden)

    Maxim V. Kharkevich

    2014-01-01

    Full Text Available Global governance as a concept defines the meaning of contemporary world politics both as a discipline and as reality. Interdependent and globalized world requires governance, and a global government has not been formed yet. The theoretical possibility of global governance without global government is proved and justified. The purpose of this article is to analytically identify possible forms of global governance. Three such forms of global governance are identified: hierarchical, market and network. In a hierarchy the governance is due to the asymmetry of power between the parties. Market control happens via anonymous pricing mechanism. Network, in contrast to the market is characterized by a closer value link between the actors, but unlike the hierarchical relationship actors are free to leave the network. Global governance takes three forms and is being implemented by different actors. To determine the most efficient form of global governance is impossible. Efficiency depends on the match between a form and an object of government. It should be noted that meta governance is likely to remain a monopoly of institutionally strong states in global governance.

    Hospitals conduct evacuation exercises to improve performance during emergency events. An essential aspect in this process is the creation of reliable and valid evaluation tools. The objective of this article is to describe the development and implications of a disaster evacuation performance tool that measures one portion of the very complex process of evacuation. Through the application of the Delphi technique and DeVellis's framework, disaster and neonatal experts provided input in developing this performance evaluation tool. Following development, content validity and reliability of this tool were assessed. Large pediatric hospital and medical center in the Midwest. The tool was pilot tested with an administrative, medical, and nursing leadership group and then implemented with a group of 68 healthcare workers during a disaster exercise of a neonatal intensive care unit (NICU). The tool has demonstrated high content validity with a scale validity index of 0.979 and inter-rater reliability G coefficient (0.984, 95% CI: 0.948-0.9952). The Delphi process based on the conceptual framework of DeVellis yielded a psychometrically sound evacuation performance evaluation tool for a NICU.

  6. Globalization, culture and psychology.

    Science.gov (United States)

    Melluish, Steve

    2014-10-01

    This article outlines the cultural and psychological effects of globalization. It looks at the impact of globalization on identity; ideas of privacy and intimacy; the way we understand and perceive psychological distress; and the development of the profession of psychology around the world. The article takes a critical perspective on globalization, seeing it as aligned with the spread of neoliberal capitalism, a tendency towards cultural homogenization, the imposition of dominant 'global north' ideas and the resultant growing inequalities in health and well-being. However, it also argues that the increased interconnectedness created by globalization allows for greater acknowledgement of our common humanity and for collective efforts to be developed to tackle what are increasingly global problems. This requires the development of more nuanced understandings of cultural differences and of indigenous psychologies.

  8. AN Fitting Reconditioning Tool

    Science.gov (United States)

    Lopez, Jason

    2011-01-01

    A tool was developed to repair or replace AN fittings on the shuttle external tank (ET). (The AN thread is a type of fitting used to connect flexible hoses and rigid metal tubing that carry fluid. It is a U.S. military-derived specification agreed upon by the Army and Navy, hence AN.) The tool is used on a drill and is guided by a pilot shaft that follows the inside bore. The cutting edge of the tool is a standard-size replaceable insert. In the typical Post Launch Maintenance/Repair process for the AN fittings, the six fittings are removed from the ET's GUCP (ground umbilical carrier plate) for reconditioning. The fittings are inspected for damage to the sealing surface per standard operations maintenance instructions. When damage is found on the sealing surface, the condition is documented. A new AN reconditioning tool is set up to cut and remove the surface damage. It is then inspected to verify the fitting still meets drawing requirements. The tool features a cone-shaped interior at 36.5 , and may be adjusted at a precise angle with go-no-go gauges to insure that the cutting edge could be adjusted as it wore down. One tool, one setting block, and one go-no-go gauge were fabricated. At the time of this reporting, the tool has reconditioned/returned to spec 36 AN fittings with 100-percent success of no leakage. This tool provides a quick solution to repair a leaky AN fitting. The tool could easily be modified with different-sized pilot shafts to different-sized fittings.

  19. National Sovereignty Vs. Globalization

    Directory of Open Access Journals (Sweden)

    Michele Marsonet

    2017-01-01

    Globalization is frequently discussed as a counterpoint to national sovereignty. It is commonly asserted that globalization has eroded national sovereignty or that it has rendered borders obsolete. In particular, it is asserted that, in a globalized world economy, governments have no alternative but to adopt neoliberal economic policies of privatization, deregulation and reductions in public expenditure. However, in the contest between social democracy and neoliberal globalization, the nation—state per se is only marginally relevant. The crucial issue is whether policy will respond to the wishes of a democratic electorate, or be tightly constrained by the ‘Golden Straightjacket’ of international financial markets.

    2014-06-01

    Full Text Available The concept of globalization has been introduced due to technical advancements that has made the world a global village. The world as is now has never been before; it is now a world where multicultural societies have developed, trade and transactions are made between countries, technology reaches every part of the world, and internet has connected every possible idea, opinion, person, and commodity with the rest of the world. In this world of globalization, education has taken a central role, as without education globalization cannot be germinated. Education is a national issue and as such, each country has its own educational policies that are emblems of that country's cultural values, belief system and historical realities. Nevertheless, the globalized world demands for multiculturalism, and commonalities amongst communities to be promoted so as to bring the world closer to accepting cultural diversities and celebrating commonalities. For these aims, educational institutions become institutions for promoting globalization by introducing various cultural and traditional beliefs to the new generation. Recently, globalization has become a popular subject of debate in national and international circiles. Globalization links individuals and institutions across the world through economic forces, digital technologies, and communication. It is moreover subjected to higher living standards, international affiliations, and multiple types of freedom. However, a major part of the world consists of under developed countries where technological advancements, communication, trade and commerce along with other economic activities are not enough to support them to be a part of the global society.

Globalization is the result of the pressure put by companies which, in turn, are under the close “magnifier” of all the involved factors (the so-called “stakeholders”. The market and the determining forces are not influenced by a political attitude nowadays marking globalization, but rather the political decisions have followed the course of economic evolutions, a trend that has always been provided by multinational corporations. In order to successfully follow up their activity, companies initiate new businesses, selling or deleting from their portfolio businesses or divisions with a decreasing tendency. Also, companies give up old rules and structures adopting new decision-making processes, control systems and mental patterns. Corporations must learn to become dynamic just like the market, if they wish to maintain, on the long run, a superior rate of income.

    The Global Earthquake Model (GEM) is a unique collaborative effort that aims to provide organizations and individuals with tools and resources for transparent assessment of earthquake risk anywhere in the world. By pooling data, knowledge and people, GEM acts as an international forum for collaboration and exchange. Sharing of data and risk information, best practices, and approaches across the globe are key to assessing risk more effectively. Through consortium driven global projects, open-source IT development and collaborations with more than 10 regions, leading experts are developing unique global datasets, best practice, open tools and models for seismic hazard and risk assessment. The year 2013 has seen the completion of ten global data sets or components addressing various aspects of earthquake hazard and risk, as well as two GEM-related, but independently managed regional projects SHARE and EMME. Notably, the International Seismological Centre (ISC) led the development of a new ISC-GEM global instrumental earthquake catalogue, which was made publicly available in early 2013. It has set a new standard for global earthquake catalogues and has found widespread acceptance and application in the global earthquake community. By the end of 2014, GEM's OpenQuake computational platform will provide the OpenQuake hazard/risk assessment software and integrate all GEM data and information products. The public release of OpenQuake is planned for the end of this 2014, and will comprise the following datasets and models: • ISC-GEM Instrumental Earthquake Catalogue (released January 2013) • Global Earthquake History Catalogue [1000-1903] • Global Geodetic Strain Rate Database and Model • Global Active Fault Database • Tectonic Regionalisation Model • Global Exposure Database • Buildings and Population Database • Earthquake Consequences Database • Physical Vulnerabilities Database • Socio-Economic Vulnerability and Resilience Indicators • Seismic

  12. Cultivating a Global Identity

    Directory of Open Access Journals (Sweden)

    Joseph de Rivera

    2015-12-01

    Full Text Available Increasing economic globalization creates conflicts that can only be constructively managed if individuals and groups realize they now belong to a single people. The required sense of such a community does not involve a social group identity—as though being human consisted of being categorized as a member of a superordinate group. Rather, it involves the realization that personal identity depends on the socio-emotional relations involved in community and that the current situation requires a community that is global rather than local or national. The nature of this personal global identity and the sort of global community that is needed is explored in this article. Developing a sense of unity amongst people has always required ritual celebration, and achieving the consciousness that persons worldwide now form a global community will require a particular type of ritual whose nature is described. The authors report on some pilot studies which demonstrate that it is possible to present the idea of global identity in a way that emphasizes personal active relationships rather than group belonging, that this may increase a sense of global identification, and that one can create a celebration that may enhance the sense of personal identity in a global community. We conclude by exploring the ways in which conceiving personal identity in communal terms has implications for research on global identity and conflict. And, finally, we report on present day initiatives that may develop a global communal consciousness, and identify and describe celebrations of community that may advance a sense of global community.

  15. European Integration and Globalization

    Directory of Open Access Journals (Sweden)

    Diana Bobica

    2010-06-01

    Full Text Available According to many, the term globalization is able to explain any phenomenon whatsoever, be it positive or negative, that takes place within the global social system. It seems like a sort of magical formula, which is to be found in the speeches of all sorts of people, be they economists, politicians, businessmen or sociologists. However this magical formula of globalization has its limitations, since it encompasses a certain amount of quibbling, beyond which not many can pass. In the context of globalization there appears the question on its role in the process of European integration. Is European integration a part of this global process or, quite on the contrary, does it present certain distinctive features, as it moulds itself differently from the globalization phenomenon? A clear-cut answer seems difficult because of the various aspects involved. Not only the general phenomenon of globalization, but also the economic integration on European level is based on the liberalization of markets and on the opening of national economies towards the exterior,having as direct consequence the intensification of trade exchanges. If from a global point of view one may talk of a market fundamentalism in that the market principles know no boundary, European integration on the other hand implies not only market economy, but also a guided and monitored action of Member Statesaccording to the needs of the whole entity, also taking into consideration - as far as possible – all aspects and consequences on social level.

    Directory of Open Access Journals (Sweden)

    Zhen Zhu

    Full Text Available The fragmentation of production across countries has become an important feature of the globalization in recent decades and is often conceptualized by the term "global value chains" (GVCs. When empirically investigating the GVCs, previous studies are mainly interested in knowing how global the GVCs are rather than how the GVCs look like. From a complex networks perspective, we use the World Input-Output Database (WIOD to study the evolution of the global production system. We find that the industry-level GVCs are indeed not chain-like but are better characterized by the tree topology. Hence, we compute the global value trees (GVTs for all the industries available in the WIOD. Moreover, we compute an industry importance measure based on the GVTs and compare it with other network centrality measures. Finally, we discuss some future applications of the GVTs.

  3. Globalization of consumer confidence

    Full Text Available The globalization of world economies and the importance of nowcasting analysis have been at the core of the recent literature. Nevertheless, these two strands of research are hardly coupled. This study aims to fill this gap through examining the globalization of the consumer confidence index (CCI by applying conventional and unconventional econometric methods. The US CCI is used as the benchmark in tests of comovement among the CCIs of several developing and developed countries, with the data sets divided into three sub-periods: global liquidity abundance, the Great Recession, and postcrisis. The existence and/or degree of globalization of the CCIs vary according to the period, whereas globalization in the form of coherence and similar paths is observed only during the Great Recession and, surprisingly, stronger in developing/emerging countries.

  4. Global corporate workplaces implementing new global workplace standards in a local context

    CERN Document Server

    Hodulak, Martin

    2017-01-01

    In recent years, multinational corporations were increasingly engaged in the development of standardized global workplace models. For their implementation and feasibility, it is decisive as how these standards fit the diverse regional workplace cultures. This topic was pursued in the course of a research project, comparing established workplaces in Germany, USA and Japan against global workplace standards of multinational corporations. The analysis confirmed the expected differences among local workplaces and on the other hand a predominant mainstream among global corporate workplace standards. Conspicuous however, are the fundamental differences between local models and corporate standards. For the implementation of global standards in local context, this implies multiple challenges on cultural, organizational and spatial level. The analysis findings provide information for assessing current projects and pinpointing optimization measures. The analysis framework further provides a tool to uncover and assess n...

    Full Text Available Many organizations are in charge of global security management. This paper outlines and argues for the construction of a theoretical and methodological framework in order to critically assess the new technopolitics currently being developed in the field of global security and which are materialized in standards. The main purpose is to design both a methodology and specific text mining tools to investigate these standards. These tools will be implemented in a platform designed to provide cartographic representations of standards and to assist the navigation of an end-user through a corpus of standards.

  9. Tools for tackling the water-energy-food nexus

    Directory of Open Access Journals (Sweden)

    Byers Edward A.

    2015-01-01

    Full Text Available Researchers and practitioners have developed many tools to study the water-energy-food nexus at a variety of scales and perspectives in order to aid decision-making. However, there is a recognised lack of tools that consider these interdependent and complex interactions in an integrated fashion. Whether to connect and federate wellestablished modelling systems and approaches, which may be challenging, or to design truly integrated tools for holistic consideration of the nexus issues, is also debated. This paper discusses four distinctly different approaches which appear to have wide-scale applicability, although demonstration of these approaches in multiple cases (besides the Polestar model which is already regional/ global is yet to be applied. Sustainable implementation of any tools will require greater accessibility such that they may be more widely deployed by practitioners. Harmonisation of results and insights between different scales, so that decision-makers may consider global-local impacts, also remains a challenge.

  10. Global Partnership in Global Earth Observations

    Science.gov (United States)

    Smirnov, A.; Obersteiner, M.

    2007-12-01

    The emergence of a global partnership on earth observations will crucially drive the configuration of future observing systems and consequently shape how socio-economic benefits are generated. In this paper we take a game-theoretical approach to model cooperation on building global earth observation systems. We consider several societies whose economies are subject to shocks mimicking major natural disasters. Economies operate optimally and lead to the best possible expected value for the social welfares in the future. In order to increase its welfare even more society can make a decision to invest into a global alerting system which lowers the risk of disasters. We start our investigation from a single-society case and show conditions under which benefits of such investment can be reaped. The propensity to invest increases with economic affluence and degree of vulnerability to natural disasters. We find that for poor and/or less vulnerable countries it is better to forbear from investment. If to consider a situation of multiple societies a strategic gaming situation emerges motivated by the fact that every society will benefit from a global system regardless of whether they invested or not. Our analysis of possible equilibrium solutions shows that similar to the formation of trading blocks (e.g. EU, NAFTA) only in the case of similar societies we will observe cooperation behavior (when all invest) and otherwise we will observe free-riding. This insight, that we might face a prisoners dilemma problem in the formation of a GEOSS, has important implications for the GEO process.

  11. Large Crater Clustering tool

    Science.gov (United States)

    Laura, Jason; Skinner, James A.; Hunter, Marc A.

    2017-08-01

    In this paper we present the Large Crater Clustering (LCC) tool set, an ArcGIS plugin that supports the quantitative approximation of a primary impact location from user-identified locations of possible secondary impact craters or the long-axes of clustered secondary craters. The identification of primary impact craters directly supports planetary geologic mapping and topical science studies where the chronostratigraphic age of some geologic units may be known, but more distant features have questionable geologic ages. Previous works (e.g., McEwen et al., 2005; Dundas and McEwen, 2007) have shown that the source of secondary impact craters can be estimated from secondary impact craters. This work adapts those methods into a statistically robust tool set. We describe the four individual tools within the LCC tool set to support: (1) processing individually digitized point observations (craters), (2) estimating the directional distribution of a clustered set of craters, back projecting the potential flight paths (crater clusters or linearly approximated catenae or lineaments), (3) intersecting projected paths, and (4) intersecting back-projected trajectories to approximate the local of potential source primary craters. We present two case studies using secondary impact features mapped in two regions of Mars. We demonstrate that the tool is able to quantitatively identify primary impacts and supports the improved qualitative interpretation of potential secondary crater flight trajectories.

  12. Collaboration pathway(s) using new tools for optimizing operational climate monitoring from space

    Helmuth, Douglas B.; Selva, Daniel; Dwyer, Morgan M.

    2014-10-01

    Consistently collecting the earth's climate signatures remains a priority for world governments and international scientific organizations. Architecting a solution requires transforming scientific missions into an optimized robust `operational' constellation that addresses the needs of decision makers, scientific investigators and global users for trusted data. The application of new tools offers pathways for global architecture collaboration. Recent (2014) rulebased decision engine modeling runs that targeted optimizing the intended NPOESS architecture, becomes a surrogate for global operational climate monitoring architecture(s). This rule-based systems tools provide valuable insight for Global climate architectures, through the comparison and evaluation of alternatives considered and the exhaustive range of trade space explored. A representative optimization of Global ECV's (essential climate variables) climate monitoring architecture(s) is explored and described in some detail with thoughts on appropriate rule-based valuations. The optimization tools(s) suggest and support global collaboration pathways and hopefully elicit responses from the audience and climate science shareholders.

  13. Chinese Entrepreneurs Go Global

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available China may be on the tipping point of explosive global growth. In response to changes in the global economy and an economic slowdown domestically, hundreds of thousands of Chinese SMEs are being encouraged to “go global” by their central and local governments. To a Chinese company, going global requires the expansion of its existing business in other countries or the development of new ventures with partners operating in other countries. Explosive growth in China may be possible, but it will depend on an appropriate strategy for going global. For a country that has firmly established itself as an international manufacturing hub, going global requires a shift in its entrepreneurial capacity, which is the focus of this article. We first assess the current situation in China to understand its current entrepreneurial focus and capacity, as well as the impetus for change. Next, we contrast the Kirznerian and Schumpeterian views of entrepreneurship to illustrate that – to go global – Chinese entrepreneurs must shift from an emphasis on exploiting pricing inefficiencies (i.e., Kirznerian entrepreneurship to an emphasis on innovation (i.e., Schumpeterian entrepreneurship. Finally, we examine unique characteristics of the business environment and culture in China, which are likely to impact the ability of Chinese entrepreneurs to go global.

  14. How global brands compete.

    Science.gov (United States)

    Holt, Douglas B; Quelch, John A; Taylor, Earl L

    2004-09-01

    It's time to rethink global branding. More than two decades ago, Harvard Business School professor Theodore Levitt argued that corporations should grow by selling standardized products all over the world. But consumers in most countries had trouble relating to generic products, so executives instead strove for global scale on backstage activities such as production while customizing product features and selling techniques to local tastes. Such "glocal" strategies now rule marketing. Global branding has lost more luster recently because transnational companies have been under siege, with brands like Coca-Cola and Nike becoming lightning rods for antiglobalization protests. The instinctive reaction of most transnational companies has been to try to fly below the radar. But global brands can't escape notice. In fact, most transnational corporations don't realize that because of their power and pervasiveness, people view them differently than they do other firms. In a research project involving 3,300 consumers in 41 countries, the authors found that most people choose one global brand over another because of differences in the brands'global qualities. Ratherthan ignore the global characteristics of their brands, firms must learn to manage those characteristics. That's critical, because future growth for most companies will likely come from foreign markets. Consumers base preferences on three dimensions of global brands--quality (signaled by a company's global stature); the cultural myths that brands author; and firms' efforts to address social problems. The authors also found that it didn't matter to consumers whether the brands they bought were American--a remarkable finding considering that the study was conducted when anti-American sentiment in many nations was on the rise.

    Banks, David C.

    1994-01-01

    This talk features two simple and useful tools for digital image processing in the UNIX environment. They are xv and pbmplus. The xv image viewer which runs under the X window system reads images in a number of different file formats and writes them out in different formats. The view area supports a pop-up control panel. The 'algorithms' menu lets you blur an image. The xv control panel also activates the color editor which displays the image's color map (if one exists). The xv image viewer is available through the internet. The pbmplus package is a set of tools designed to perform image processing from within a UNIX shell. The acronym 'pbm' stands for portable bit map. Like xv, the pbm plus tool can convert images from and to many different file formats. The source code and manual pages for pbmplus are also available through the internet. This software is in the public domain.

  17. DengueTools: innovative tools and strategies for the surveillance and control of dengue

    Directory of Open Access Journals (Sweden)

    Annelies Wilder-Smith

    2012-03-01

    Full Text Available Dengue fever is a mosquito-borne viral disease estimated to cause about 230 million infections worldwide every year, of which 25,000 are fatal. Global incidence has risen rapidly in recent decades with some 3.6 billion people, over half of the world's population, now at risk, mainly in urban centres of the tropics and subtropics. Demographic and societal changes, in particular urbanization, globalization, and increased international travel, are major contributors to the rise in incidence and geographic expansion of dengue infections. Major research gaps continue to hamper the control of dengue. The European Commission launched a call under the 7th Framework Programme with the title of ‘Comprehensive control of Dengue fever under changing climatic conditions’. Fourteen partners from several countries in Europe, Asia, and South America formed a consortium named ‘DengueTools’ to respond to the call to achieve better diagnosis, surveillance, prevention, and predictive models and improve our understanding of the spread of dengue to previously uninfected regions (including Europe in the context of globalization and climate change.The consortium comprises 12 work packages to address a set of research questions in three areas: Research area 1: Develop a comprehensive early warning and surveillance system that has predictive capability for epidemic dengue and benefits from novel tools for laboratory diagnosis and vector monitoring. Research area 2: Develop novel strategies to prevent dengue in children. Research area 3: Understand and predict the risk of global spread of dengue, in particular the risk of introduction and establishment in Europe, within the context of parameters of vectorial capacity, global mobility, and climate change.In this paper, we report on the rationale and specific study objectives of ‘DengueTools’.

    RSP Tooling{trademark} is a spray forming technology tailored for producing molds and dies. The approach combines rapid solidification processing and net-shape materials processing in a single step. The general concept involves converting a mold design described by a CAD file to a tooling master using a suitable rapid prototyping (RP) technology such as stereolithography. A pattern transfer is made to a castable ceramic, typically alumina or fused silica (Figure 1). This is followed by spray forming a thick deposit of a tooling alloy on the pattern to capture the desired shape, surface texture, and detail. The resultant metal block is cooled to room temperature and separated from the pattern. The deposit's exterior walls are machined square, allowing it to be used as an insert in a standard mold base. The overall turnaround time for tooling is about 3 to 5 days, starting with a master. Molds and dies produced in this way have been used in high volume production runs in plastic injection molding and die casting. A Cooperative Research and Development Agreement (CRADA) between the Idaho National Engineering and Environmental Laboratory (INEEL) and Grupo Vitro has been established to evaluate the feasibility of using RSP Tooling technology for producing molds and dies of interest to Vitro. This report summarizes results from Phase I of this agreement, and describes work scope and budget for Phase I1 activities. The main objective in Phase I was to demonstrate the feasibility of applying the Rapid Solidification Process (RSP) Tooling method to produce molds for the manufacture of glass and other components of interest to Vitro. This objective was successfully achieved.

    2017-06-01

    The generalization of the Mishchenko-Fomenko theorem for symplectic superintegrable systems to the case of an arbitrary, not necessarily compact, invariant submanifold allows giving a global description of a superintegrable Hamiltonian system, which can be split into several nonequivalent globally superintegrable systems on nonoverlapping open submanifolds of the symplectic phase manifold having both compact and noncompact invariant submanifolds. A typical example of such a composition of globally superintegrable systems is motion in a centrally symmetric field, in particular, the two-dimensional Kepler problem.

    In this paper, we investigate the weak Gorenstein global dimensions. We are mainly interested in studying the problem when the left and right weak Gorenstein global dimensions coincide. We first show, for GF-closed rings, that the left and right weak Gorenstein global dimensions are equal when they are finite. Then, we prove that the same equality holds for any two-sided coherent ring. We conclude the paper with some examples and a brief discussion of the scope and limits of our results.

    The GNEMRE Dendro Tool provides a previously unrealized analysis capability in the field of nuclear explosion monitoring. Dendro Tool allows analysts to quickly and easily determine the similarity between seismic events using the waveform time-series for each of the events to compute cross-correlation values. Events can then be categorized into clusters of similar events. This analysis technique can be used to characterize historical archives of seismic events in order to determine many of the unique sources that are present. In addition, the source of any new events can be quickly identified simply by comparing the new event to the historical set.

  15. Transparent Global Seismic Hazard and Risk Assessment

    Science.gov (United States)

    Smolka, Anselm; Schneider, John; Pinho, Rui; Crowley, Helen

    2013-04-01

    Vulnerability to earthquakes is increasing, yet advanced reliable risk assessment tools and data are inaccessible to most, despite being a critical basis for managing risk. Also, there are few, if any, global standards that allow us to compare risk between various locations. The Global Earthquake Model (GEM) is a unique collaborative effort that aims to provide organizations and individuals with tools and resources for transparent assessment of earthquake risk anywhere in the world. By pooling data, knowledge and people, GEM acts as an international forum for collaboration and exchange, and leverages the knowledge of leading experts for the benefit of society. Sharing of data and risk information, best practices, and approaches across the globe is key to assessing risk more effectively. Through global projects, open-source IT development and collaborations with more than 10 regions, leading experts are collaboratively developing unique global datasets, best practice, open tools and models for seismic hazard and risk assessment. Guided by the needs and experiences of governments, companies and citizens at large, they work in continuous interaction with the wider community. A continuously expanding public-private partnership constitutes the GEM Foundation, which drives the collaborative GEM effort. An integrated and holistic approach to risk is key to GEM's risk assessment platform, OpenQuake, that integrates all above-mentioned contributions and will become available towards the end of 2014. Stakeholders worldwide will be able to calculate, visualise and investigate earthquake risk, capture new data and to share their findings for joint learning. Homogenized information on hazard can be combined with data on exposure (buildings, population) and data on their vulnerability, for loss assessment around the globe. Furthermore, for a true integrated view of seismic risk, users can add social vulnerability and resilience indices to maps and estimate the costs and benefits
