    Many global challenges, including obesity, health care costs, and climate change, could be addressed in part by increasing the use of bicycles for transportation. Concern about the safety of bicycling on roadways is frequently cited as a deterrent to increasing bicycle use in the USA. The use of effective signage along roadways might help alleviate these concerns by increasing knowledge about the rights and duties of bicyclists and motorists, ideally reducing crashes. We administered a web-based survey, using Twitter for recruitment, to examine how well three US traffic control devices communicated the message that bicyclists are permitted in the center of the travel lane and do not have to "get out of the way" to allow motorists to pass without changing lanes: "Bicycles May Use Full Lane" and "Share the Road" signage, and Shared Lane Markings on the pavement. Each was compared to an unsigned roadway. We also asked respondents whether it was safe for a bicyclist to occupy the center of the travel lane. "Bicycles May Use Full Lane" signage was the most consistently comprehended device for communicating the message that bicyclists may occupy the travel lane and also increased perceptions of safety. "Share the Road" signage did not increase comprehension or perceptions of safety. Shared Lane Markings fell somewhere between. "Bicycles May Use Full Lane" signage showed notable increases in comprehension among novice bicyclists and private motor vehicle commuters, critical target audiences for efforts to promote bicycling in the USA. Although limited in scope, our survey results are indicative and suggest that Departments of Transportation consider replacing "Share the Road" with "Bicycles May Use Full Lane" signage, possibly combined with Shared Lane Markings, if the intent is to increase awareness of roadway rights and responsibilities. Further evaluation through virtual reality simulations and on-road experiments is merited.

  5. Implementation Scenarios for Electric Vehicle Roadway Wireless Power Transfer; NREL (National Renewable Energy Laboratory)

    Energy Technology Data Exchange (ETDEWEB)

    Meintz, A.; Markel, T.; Burton, E.; Wang, L.; Gonder, J.; Brooker, A.

    2015-06-05

    Analysis has been performed on the Transportation Secure Data Center (TSDC) warehouse of collected GPS second-by-second driving profile data of vehicles in the Atlanta, Chicago, Fresno, Kansas City, Los Angeles, Sacramento, and San Francisco Consolidated Statistical Areas (CSAs) to understand in-motion wireless power transfer introduction scenarios. In this work it has been shown that electrification of 1% of road miles could reduce fuel use by 25% for Hybrid Electric Vehicles (HEVs) in these CSAs. This analysis of strategically located infrastructure offers a promising approach to reduced fuel consumption; however, even the most promising 1% of road miles determined by these seven analysis scenarios still represent an impressive 2,700 miles of roadway to electrify. Therefore to mitigate the infrastructure capital costs, integration of the grid-tied power electronics in the Wireless Power Transfer (WPT) system at the DC-link to photovoltaic and/or battery storage is suggested. The integration of these resources would allow for the hardware to provide additional revenue through grid services at times of low traffic volumes and conversely at time of high traffic volumes these resources could reduce the peak demand that the WPT system would otherwise add to the grid.

    2014-01-01

    Long-term exposure to traffic pollution has been associated with adverse health outcomes in children and adolescents. A significant number of schools may be located near major roadways, potentially exposing millions of children to high levels of traffic pollution, but this hypothesis has not been evaluated nationally. We obtained data on the location and characteristics of 114,644 US public and private schools, grades prekindergarten through 12, and calculated their distance to the nearest major roadway. In 2005-2006, 3.2 million students (6.2%) attended 8,424 schools (7.3%) located within 100 m of a major roadway, and an additional 3.2 million (6.3%) students attended 8,555 (7.5%) schools located 100-250 m from a major roadway. Schools serving predominantly Black students were 18% (95% CI, 13-23%) more likely to be located within 250 m of a major roadway. Public schools eligible for Title I programs and those with a majority of students eligible for free/reduced price meals were also more likely to be near major roadways. In conclusion, 6.4 million US children attended schools within 250 m of a major roadway and were likely exposed to high levels of traffic pollution. Minority and underprivileged children were disproportionately affected, although some results varied regionally.

  13. Underground roadway drivage with heading machines in Indian coal industry

    Energy Technology Data Exchange (ETDEWEB)

    Mukherjee, T.K.

    1983-03-01

    Heading machines have assumed a very important place in underground roadway drivage. They are not only a compromise between ''drill-and-blast'' technique and full-face machines, but are also an economic and versatile form of mechanised roadway drivage. Since the advantages gained by heading machines are considerable, the use of these machines is becoming popular in underground roadway drivage. Experience with continuous miner and heading machines in Indian coal mines is very limited compared to that of Western countries. In 1964-65, for the first time, two units of Lee Norse Miner were used at Kunostoria Colliery of Bengal Coal Company. In 1966, two units of Joy Continuous Miner were introduced at Chalkari Colliery of National Coal Development Corporation, but had to be adandoned because of heavy make of water at the installation site. A Russian PK-3 heading machine was used limitedly during the development of Banki Colliery, Madhya Pradesh. A Demag Unicorn VS-1 machine operated for the development of roadways at Jitpur and Chasnala Collieries of IISCO between 1967-70. With this machine, progress of 7 m per day was attained in level roadways and of about 2 m per day in steep raises.

  15. Probabilistic assessment of roadway departure risk in a curve

    Science.gov (United States)

    Rey, G.; Clair, D.; Fogli, M.; Bernardin, F.

    2011-10-01

    Roadway departure while cornering constitutes a major part of car accidents and casualties in France. Even though drastic policy about overspeeding contributes to reduce accidents, there obviously exist other factors. This article presents the construction of a probabilistic strategy for the roadway departure risk assessment. A specific vehicle dynamic model is developed in which some parameters are modelled by random variables. These parameters are deduced from a sensitivity analysis to ensure an efficient representation of the inherent uncertainties of the system. Then, structural reliability methods are employed to assess the roadway departure risk in function of the initial conditions measured at the entrance of the curve. This study is conducted within the French national road safety project SARI that aims to implement a warning systems alerting the driver in case of dangerous situation.

  16. National Identity as a Factor of Inter-Cultural Communication

    Directory of Open Access Journals (Sweden)

    Elizaveta A. Volkova

    2015-01-01

    Full Text Available The article deals with the definition and origin of the notions «mentality (identity» and «national mentality (identity» focusing on their complex essence. The article names factors that affect the formation of national identity, at the same time pointing out the aspect of human life that the identity itself affects. The notion «national identity» is revealed via its vocabulary definitions. National identity is analyzed as a factor of inter-cultural communication, its role and importance in this communication are also analyzed. One of the objectives of the research is signing out the limits of the concepts «national identity» and «inter-cultural communication» and revealing the conditions of their interaction and mutual dependence. National identity is a complex notion, which complexity lies within the combination of mental and emotional, spiritual elements. This factor adds extra difficulty into understanding, as well as investigating the notion of national identity. Thus it is not rarely ignored in linguistics, international communication, even in teaching languages. However, nowadays, when globalization makes international contacts and communication widely accessible, many people meet unexpected difficulties that derive from ignoring national identity factor. That is why recently it is getting more and more obvious that taking national identity into consideration can be one of the main keys to successful communication at all levels.

    Research literature has yet to quantify and describe how students with complex communication needs are supported in the classroom and how special educators are being prepared to offer support. This study sought out special educators to complete a survey about their students with complex communication needs. Over 4,000 teachers representing 50 states reported on the communicative and behavioral characteristics of 15,643 students. Teachers described the training they have received and instructional approaches they used. The majority of students were reported to use speech as their primary communication mode. Over half of students utilizing alternative and augmentative communication (AAC) were reported to have non-proficient communication. Teacher training varied across respondents as well as the supports they used to support these students in the classroom. The majority of students with disabilities using AAC when communicating across the nation are not proficiently communicating. Implications and recommendations will be discussed.

  1. Brazilian science communication research: national and international contributions.

    Science.gov (United States)

    Barata, Germana; Caldas, Graça; Gascoigne, Toss

    2017-08-31

    Science communication has emerged as a new field over the last 50 years, and its progress has been marked by a rise in jobs, training courses, research, associations, conferences and publications. This paper describes science communication internationally and the trends and challenges it faces, before looking at the national level. We have documented science communication activities in Brazil, the training courses, research, financial support and associations/societies. By analyzing the publication of papers, dissertations and theses we have tracked the growth of this field, and compared the level of activity in Brazil with other countries. Brazil has boosted its national research publications since 2002, with a bigger contribution from postgraduate programs in education and communication, but compared to its national research activity Brazil has only a small international presence in science communication. The language barrier, the tradition of publishing in national journals and the solid roots in education are some of the reasons for that. Brazil could improve its international participation, first by considering collaborations within Latin America. International publication is dominated by the USA and the UK. There is a need to take science communication to the next level by developing more sophisticated tools for conceptualizing and analyzing science communication, and Brazil can be part of that.

  2. Information and Communication Technology: Gender Issues in Developing Nations

    Directory of Open Access Journals (Sweden)

    Kimberly Betz Leahy

    2003-01-01

    Full Text Available As Developing Nations seek to leverage scarce resources toward the goal of achieving a developed status they must reevaluate past practices and explore available and affordable technologies. Where in-formation and communication infrastructures are weak, use of low-cost, easily distributed technologies have proven effective. Still, many developing nations have failed to incorporate a resource in great abundance, their women, to use these new technologies to greatest advantage. This paper will address the implications of women's lack of economic and educational parity, and offer examples of how the education of women through the use of information and communication technology can enhance a nation's gross domestic product (GDP.

  8. Insights on the National Status of Nuclear Crisis Communication

    International Nuclear Information System (INIS)

    Lee, Chang Ju; Hah, Yeon Hee; Oh, Kju Myeng

    2010-01-01

    In general, the term, 'risk communication' can be defined as a two way interaction process which can share internal attributes between personals, organizations, and others, where it usually comes from a 'normal risk' in areas of safety, health, security, environment, etc. We can also classify the communication issues with 'general case,' 'local case,' and 'crisis case,' respectively, in terms of the impacts on public perception. As a general concept, 'nuclear crisis' can be defined as a situation where nuclear radiological emergency plan and procedures shall be applied to cope with radiological accidents or emergencies which may occur at the nuclear power plant or radioisotopes using companies, hospitals, and universities. 'Crisis communication' refers one of the activities done by the Nuclear Regulatory Organizations (NRO) in order to protect the public and the environment from the possible harmful effects. There is an international initiative for searching a practical 'road map' with good practice guidance for NROs of each country on crisis communication, covering planning during normal situations, lessons learnt from emergencies or challenging events, and media strategy. The 'road map' is based on the identification of best practices and challenges when facing either planned situations or unexpected situations which might affect NRO's credibility. It is also important to fully know how our NRO operates in order to communicate with the public and the media within the complex network of public organizations, covering both the national and local perspective. In this paper, we want to survey relevant illustrations of NRO's flux of work concerning public, media communication cases in abnormal/crisis/emergency situations. Also, we will talk about the responsibilities of each area and clarify who is in charge of external communication. By this way, we can find an adequate scheme showing the involvement of NRO with other public organizations during a crisis situation

    Sweden's national communication to the UN Convention on Climate Change describes everything about the emission and absorption of greenhouse gases, the motives and forces behind emissions, and official Swedish climate policies. Every five years, Sweden submits a communication on practical climate efforts in Sweden to the UN Convention on Climate Change. The Swedish Environmental Protection Board has coordinated the work of producing the basic documentation for the communication, which also describes the measures already taken and those planned for the future. In addition, scenarios have been adopted for developments in Swedish greenhouse gas emissions, Sweden's vulnerability and Swedish research into the climate and climate change

  20. Integrating Communication Best Practices in the Third National Climate Assessment

    Science.gov (United States)

    Hassol, S. J.

    2014-12-01

    Modern climate science assessments now have a history of nearly a quarter-century. This experience, together with important advances in relevant social sciences, has greatly improved our ability to communicate climate science effectively. As a result, the Third National Climate Assessment (NCA) was designed to be truly accessible and useful to all its intended audiences, while still being comprehensive and scientifically accurate. At a time when meeting the challenge of climate change is increasingly recognized as an urgent national and global priority, the NCA is proving to be valuable to decision-makers, the media, and the public. In producing this latest NCA, a communication perspective was an important part of the process from the beginning, rather than an afterthought as has often been the case with scientific reports. Lessons learned from past projects and science communications research fed into developing the communication strategy for the Third NCA. A team of editors and graphic designers worked closely with the authors on language, graphics, and photographs throughout the development of the report, Highlights document, and other products. A web design team helped bring the report to life online. There were also innovations in outreach, including a network of organizations intended to extend the reach of the assessment by engaging stakeholders throughout the process. Professional slide set development and media training were part of the preparation for the report's release. The launch of the NCA in May 2014 saw widespread and ongoing media coverage, continued references to the NCA by decision-makers, and praise from many quarters for its excellence in making complex science clear and accessible. This NCA is a professionally crafted report that exemplifies best practices in 21st century communications.

  2. The National Climate Assessment as a Resource for Science Communication

    Science.gov (United States)

    Somerville, R. C. J.

    2014-12-01

    The 2014 Third National Climate Assessment (NCA3) is scientifically authoritative and features major advances, relative to other assessments produced by several organizations. NCA3 is a valuable resource for communicating climate science to a wide variety of audiences. Other assessments were often overly detailed and laden with scientific jargon that made them appear too complex and technical to many in their intended audiences, especially policymakers, the media, and the broad public. Some other assessments emphasized extensive scientific caveats, quantitative uncertainty estimates and broad consensus support. All these attributes, while valuable in research, carry the risk of impeding science communication to non-specialists. Without compromising scientific accuracy and integrity, NCA3 is written in exceptionally clear and vivid English. It includes outstanding graphics and employs powerful techniques aimed at conveying key results unambiguously to a wide range of audiences. I have used NCA3 as a resource in speaking about climate change in three very different settings: classroom teaching for undergraduate university students, presenting in academia to historians and other non-scientists, and briefing corporate executives working on renewable energy. NCA3 proved the value of developing a climate assessment with communication goals and strategies given a high priority throughout the process, not added on as an afterthought. I draw several lessons. First, producing an outstanding scientific assessment is too complex and demanding a task to be carried out by scientists alone. Many types of specialized expertise are also needed. Second, speaking about science to a variety of audiences requires an assortment of communication skills and tools, all tailored to specific groups of listeners. Third, NCA3 is scientifically impeccable and is also an outstanding example of effective communication as well as a valuable resource for communicators.

    This study investigated at a country level how cross-national differences in medical communication can be understood from the first four of Hofstede's cultural dimensions, i.e. power distance, uncertainty avoidance, individualism/collectivism and masculinity/femininity, together with national wealth. A total of 307 general practitioners (GPs) and 5820 patients from Belgium, Estonia, Germany, Great Britain, the Netherlands, Poland, Romania, Spain, Sweden and Switzerland participated in the study. Medical communication was videotaped and assessed using Roter's interaction analysis system (RIAS). Additional context information of physicians (gender, job satisfaction, risk-taking and belief of psychological influence on diseases) and patients (gender, health condition, diagnosis and medical encounter expectations) was gathered by using questionnaires. Countries differ considerably form each other in terms of culture dimensions. The larger a nation's power distance, the less room there is for unexpected information exchange and the shorter the consultations are. Roles are clearly described and fixed. The higher the level of uncertainty avoidance, the less attention is given to rapport building, e.g. less eye contact. In 'masculine' countries there is less instrumental communication in the medical interaction, which was contrary to expectations. In wealthy countries, more attention is given to psychosocial communication. The four culture dimensions, together with countries' wealth, contribute importantly to the understanding of differences in European countries' styles of medical communication. Their predictive power reaches much further than explanations along the north/south or east/west division of Europe. The understanding of these cross-national differences is a precondition for the prevention of intercultural miscommunication. Improved understanding may occur at microlevel in the medical encounter, as well as on macrolevel in pursuing more effective cooperation and

    2009-05-01

    Combat resiliency is the ability of a commander to prosecute, control, and consolidate his/her's sphere of influence in adverse and changing conditions. To support this, an infrastructure must exist that allows the commander to view the world in varying degrees of granularity with sufficient levels of detail to permit confidence estimates to be levied against decisions and course of actions. An infrastructure such as this will include the ability to effectively communicate context and relevance within and across the battle space. To achieve this will require careful thought, planning, and understanding of a network and its capacity limitations in post-event command and control. Relevance and impact on any existing infrastructure must be fully understood prior to deployment to exploit the system's full capacity and capabilities. In this view, the combat communication network is considered an integral part of or National communication network and infrastructure. This paper will describe an analytical tool set developed at ORNL and RNI incorporating complexity theory, advanced communications modeling, simulation, and visualization technologies that could be used as a pre-planning tool or post event reasoning application to support response and containment.

  16. Design Of Overhead Roadway At Road Intersection

    Directory of Open Access Journals (Sweden)

    Raji

    2017-08-01

    Full Text Available This project deals with the Design of overhead-roadway located at CHALLENGE junction which is a T-junction. Analysis of the existing conditions was carried out to proffers solution to the cause of the problems occurring due to the vehicle competing for space at this intersection. Before carrying out the analysis a traffic surveys at peak hours for morning 0730 to 0830 am and afternoon 0300 to 0400 pm were conducted using 15 minutes interval. From the analysis it was found out that the peak hour factor and flow rate was 0.88 and 1656pcphpl respectively corresponding to LOS E. This implies that the capacity of the existing road is no longer able to accommodate the traffic flow hence overhead roadway was introduced to improve the efficiency of the intersection. The overhead-roadway is of 140 m length with 7 spans 20 m per span. It consists of a deck slab longitudinal girders cross girders deck beam pier foundation and retailing wall. All structural parts for this Flyover were designed using Staad professional software package and Manual method.

  15. Risk analysis for roadways subjected to multiple landslide-related hazards

    Science.gov (United States)

    Corominas, Jordi; Mavrouli, Olga

    2014-05-01

    Roadways through mountainous terrain often involve cuts and landslide areas whose stability is precarious and require protection and stabilization works. To optimize the allocation of resources, government and technical offices are increasingly interested in both the risk analysis and assessment. Risk analysis has to consider the hazard occurrence and the consequences. The consequences can be both direct and indirect. The former include the costs regarding the repair of the roadway, the damage of vehicles and the potential fatalities, while the latter refer to the costs related to the diversion of vehicles, the excess of distance travelled, the time differences, and tolls. The type of slope instabilities that may affect a roadway may vary and its effects as well. Most current approaches either consider a single hazardous phenomenon each time, or if applied at small (for example national) scale, they do not take into account local conditions at each section of the roadway. The objective of this work is the development of a simple and comprehensive methodology for the assessment of the risk due to multiple hazards along roadways, integrating different landslide types that include rockfalls, debris flows and considering as well the potential failure of retaining walls. To quantify risk, all hazards are expressed with a common term: their probability of occurrence. The methodology takes into consideration the specific local conditions along the roadway. For rockfalls and debris flow a variety of methods for assessing the probability of occurrence exists. To assess the annual probability of failure of retaining walls we use an indicator-based model that provides a hazard index. The model parameters consist in the design safety factor, and further anchorage design and construction parameters. The probability of failure is evaluated in function of the hazard index and next corrected (in terms of order of magnitude) according to in situ observations for increase of two

    Full Text Available Dallas Roadway Products (DRP soil stabilization technology can effectively improve road foundation construction and with it the strength of roadway sub-grades and sub-bases. Soil samples were collected from roads in Nigeria’s six geo-political regions. DRP LS-40 (lignate sulfonate and DRP SA-44 (sulfuric acid were added to the soil materials. The mixture precipitated a non-reversible chemical reaction that involved a permanent change in the soil structure. The chemicals reacted with the clay content, increasing the soil material plasticity. In non-plastic soils, clay materials were added to the soil, which was then pulverised. The study showed that DRP soil stabilisation chemicals can render poor, unsuitable or marginally deficient soils apt for use as a sub-base or base in roadway construction.

    La tecnología de Dallas Roadway Products (DRP constituye una metodología eficaz para mejorar la construcción de las capas inferiores del firme de calzadas y con ella la resistencia de las bases y sub-bases de las carreteras. En esta investigación se recogen muestras del terreno que constituye las carreteras existentes en las seis regiones geopolíticas nigerianas. Al incorporar a las muestras el DRP LS-40 (lignosulfonato y el DRP SA-44 (ácido sulfúrico, la mezcla acelera una reacción química no reversible que produce una modificación permanente del entramado del suelo. La reacción de las sustancias químicas con la arcilla del suelo aumenta su plasticidad. A los suelos sin plasticidad se agregan materiales arcillosos, procediéndose a continuación a la pulverización del material resultante. Según los resultados obtenidos, las sustancias químicas de estabilización de suelos de DRP pueden transformar los suelos pobres, inapropiados o deficientes en materiales adecuados para servir como bases o sub-bases de las carreteras.

    This paper describes what constitute an Effective Communications System for a National Oil Spill Contingency Plan. It discusses the system available in Nigeria for the oil exploration and producing companies, the Nigerian National Petroleum Corporation (NNPC) and the only oil spill response cooperative, the Clean Nigeria Associates (CNA). The Emergency Communications System which the companies had in place for some time, but is no longer functioning because of bureaucratic problems, is mentioned. The paper also mentioned the need to integrate the various separate systems already in use to provide effective communication for proper oil spill response. It recognizes the need for support from the Ministry of Communications and the two government agencies, NITEL and NET which provide telephone services in Nigeria.

    Science.gov (United States)

    Berg, Katrina; Sun, Christina J; Babalola, Stella

    2012-01-01

    This study explores what constructs are associated with parent-adolescent communication about AIDS/sexually transmitted infections (STIs) and sexual relationships in Nigeria. The analyses use data from the 2007 National HIV/AIDS and Reproductive Health Survey on 2593 men and women who had at least one child over the age of 12 years. The respondents were classified as low, medium, or high communicators. Low communicators were parents who did not talk to their child about either AIDS/STIs or sexual relationships. Medium communicators were parents who discussed only one topic with at least one child. High communicators were parents who discussed both topics with at least one child. Logistic regression was used to compare high communicators with low/medium communicators. There are commonalities and differences among men and women in the factors associated with parent-adolescent communication. Age, religion, and knowing where to obtain information about HIV/AIDS were associated with the extent of communication, regardless of the parent's gender. Perceived social support was an important correlate for fathers, while knowledge of female STI symptoms showed a significant association only for mothers. Programmatic and communication implications of the findings include addressing men and women differently, developing strategies to specifically reach younger parents and Muslims, and increasing general awareness of HIV/AIDS information resources. Further research is needed to understand the context, content, and timing of parent-adolescent conversations about AIDS/STIs and sexual relationships and how these factors affect the sexual behaviors of adolescents.

    Analyzes methods of mine drivage in Poland and materials handling systems. Of 1,620 km of roadways driven in 1982, 12% fell on roadways driven in coal and 88% on roadways driven in stone or stone and coal. Roadways driven in coal in most cases were situated at depths from 500 to 700 m. Roadway cross-section ranged from 12 to 18 m{sup 2}. Roadways in stone or stone and coal were driven by drilling and blasting. Loaders were used for stone handling. Roadways in coal were driven by heading machines. Advance rates of mine drivage by heading machines were 2 to 3 times higher than those by drilling and blasting with loaders for stone handling. Basic statistical data characterizing roadways and drivage methods are evaluated: roadway dimensions and depth advance rate depending on drivage methods and mining condition, types of heading machines and loaders.

    1996-01-01

    Health care services delivered from a distance, known collectively as telemedicine, are being increasingly demonstrated on various transmission media. Telemedicine activities have included diagnosis by a doctor at a remote location, emergency and disaster medical assistance, medical education, and medical informatics. The ability of communications satellites to offer communication channels and bandwidth on demand, connectivity to mobile, remote and under served regions, and global access will afford them a critical role for telemedicine applications within the National and Global Information Infrastructure (NII/GII). The importance that communications satellites will have in telemedicine applications within the NII/GII the differences in requirements for NII vs. GII, the major issues such as interoperability, confidentiality, quality, availability, and costs, and preliminary conclusions for future usability based on the review of several recent trails at national and global levels are presented.

  13. Effectiveness of a national media campaign to promote parent-child communication about sex.

    Science.gov (United States)

    Davis, Kevin C; Evans, W Douglas; Kamyab, Kian

    2013-02-01

    Although there is debate on the effectiveness of youth-focused abstinence education programs, research confirms that parents can influence their children's decisions about sexual behavior. To leverage parent-based approaches to adolescent sexual health, the U.S. Department of Health and Human Services launched the Parents Speak Up National Campaign (PSUNC) to encourage parent-child communication about sex. Previous experimental studies have found the campaign to be efficacious in increasing parent-child communication. But to date, the actual reach of the campaign and its real-world effectiveness in promoting parent-child communication has not been established. The present study addresses this gap. The authors surveyed 1,804 parents of 10- to14-year-old children from the nationally representative Knowledge Networks online panel. The survey included questions about parents' awareness of PSUNC ads and parent-child communication behaviors. The authors also analyzed market-level data on campaign gross rating points, a measure of market-level intensity of PSUNC advertising in the United States. Multivariate regressions were used to examine the association between PSUNC exposure and a three-item scale for parent-child communication. Overall, 59.4% of parents in the sample reported awareness of PSUNC. The authors found that higher market-level PSUNC gross rating points were associated with increased parent-child communication. Similar relationships were observed between self-reported awareness of PSUNC and increased frequency of communication and recommendations to wait. These associations were particularly strong among mothers. This study provides the first field-based data on the real-world reach and effectiveness of PSUNC among parents. The data support earlier experimental trials of PSUNC, showing that the campaign is associated with greater parent-child communication, primarily among mothers. Further research may be needed to develop additional messages for fathers.

  14. High-Fidelity Roadway Modeling and Simulation

    Wang, Jie; Papelis, Yiannis; Shen, Yuzhong; Unal, Ozhan; Cetin, Mecit

    2010-01-01

    Roads are an essential feature in our daily lives. With the advances in computing technologies, 2D and 3D road models are employed in many applications, such as computer games and virtual environments. Traditional road models were generated by professional artists manually using modeling software tools such as Maya and 3ds Max. This approach requires both highly specialized and sophisticated skills and massive manual labor. Automatic road generation based on procedural modeling can create road models using specially designed computer algorithms or procedures, reducing the tedious manual editing needed for road modeling dramatically. But most existing procedural modeling methods for road generation put emphasis on the visual effects of the generated roads, not the geometrical and architectural fidelity. This limitation seriously restricts the applicability of the generated road models. To address this problem, this paper proposes a high-fidelity roadway generation method that takes into account road design principles practiced by civil engineering professionals, and as a result, the generated roads can support not only general applications such as games and simulations in which roads are used as 3D assets, but also demanding civil engineering applications, which requires accurate geometrical models of roads. The inputs to the proposed method include road specifications, civil engineering road design rules, terrain information, and surrounding environment. Then the proposed method generates in real time 3D roads that have both high visual and geometrical fidelities. This paper discusses in details the procedures that convert 2D roads specified in shape files into 3D roads and civil engineering road design principles. The proposed method can be used in many applications that have stringent requirements on high precision 3D models, such as driving simulations and road design prototyping. Preliminary results demonstrate the effectiveness of the proposed method.

  15. Methods for protecting mine roadways used by two faces

    Energy Technology Data Exchange (ETDEWEB)

    Katkov, G A; Dimanshtein, A S

    1983-09-01

    Use of a mine roadway by two longwall faces reduces mine drivage by half and positively influences ventilation and mine haulage. Economic effects of repeated use of mine roadways depend on strata control cost and repair of support systems damaged or deformed by rock strata stress. Use of strips of pneumatic stowing along mine roadways is uneconomical due to low support strength and significant subsidence of the waste rock strip under rock strata stress. Use of timber cribbings as well as blocks of reinforced concrete for strata control is uneconomical due to their high damage rate and low support capacity. Investigations carried out by the IGD Im. A.A. Skochinski Institute and other research institutes show that use of hardening stowing is superior to other methods for strata control in mine roadways used by two longwall faces. Hardening stowing (on a cement basis) is prepared by the SB-67 or the PBM-2Eh machines and by other systems used for guniting in coal mines. The optimum dimensions of a strip of hardening stowing depend on coal seam thickness and mechanical properties of the surrounding rock strata. Use of hardening stowing successfully controls roof subsidence in mine roadways and reduces support deformation. Examples of hardening stowing use in some Donbass coal mines are discussed.

    Required by Congress under the Global Change Act of 1990 to inform the nation on the findings of current climate research, the Third U.S. National Climate Assessment (NCA), released in May 2014, is a rich resource for climate change education, communications and outreach (ECO). Using a website design with mobile applications in mind, NCA takes advantage of mobile learning technology which is revolutionizing how, when and where learning occurs. In an effort to maximize the "teachable moments" inherent in the assessment, a community of experts from the National Center for Science Education and the CLEAN Network, working under the auspices of the National Climate Assessment Network (NCAnet) Education Affinity Group, have developed a series of NCA Learning Pathways that match key NCA messages and resources with reviewed educational materials and trusted online information sources, thereby adding pedagogical depth to the assessment. The NCA Learning Pathways, which focus on the regional chapters of the report, are designed make climate change science more local, human, relevant and, if properly framed by educators and communicators, hopeful for learners. This paper touches on the challenges and opportunities of infusing climate education, communications and outreach into curriculum and society, and details the development and content of NCA Learning Pathways, which are available online through NOAA's Climate.gov website: http://www.climate.gov/teaching

    2011-06-01

    This report was based on a survey on national crises to which 17 countries responded, drawing on their own communication expertise and know-how in emergency response. Considering a previous analysis of communication during abnormal situations, this guidance seeks to help nuclear regulatory organisations (NROs) widen their common knowledge of communication requirements and practices amongst different countries, as well as existing informative tools to use before, during and after crises. The purpose of this document is to report on the survey's key findings and to draw a road map to improve the effectiveness of crisis communication management under all types of critical situations (from anomalies to major accidents). Among other topics, this report includes practical information on reaction time, elaboration and delivery of coordinated and accurate messages, new channels to be explored, and priority challenges to ensure transparency under close public scrutiny. It should be kept in mind that the present document was mostly completed before the nuclear crisis in Fukushima (Japan) that followed the catastrophic natural disasters that affected the region in March 2011. Therefore, this report does not take into account the necessary analysis of national practices derived from international crisis communication management. NROs commonly agree that crisis communication is linked to media pressure and reputation risk, and all realize that their credibility could be jeopardised. Because crises demand a quick response, an established communication plan by the NRO to deliver accurate information in the initial stage is critical. Providing early information, expected of nuclear safety authorities by the public, helps ensure transparency under high pressure and public scrutiny. Regular public communication about the NRO and planned emergency actions in advance of a crisis helps to build the NRO's reputation as a reliable, independent and trustworthy source of information

    2012-01-01

    Full Text Available In South Africa social and behavioural communication interventions are a critical component of HIV/AIDS prevention, and numerous communication campaigns have been implemented intensively across the country through government initiatives and nongovernmental organisations over the past decade. The aim of this paper is to assess the reach of HIV and AIDS communication campaigns in conjunction with contributions to knowledge, attitudes, and HIV risk behaviours in the general population in South Africa. The sample included in this nationally representative cross-sectional survey was 13234 people aged 15–55 years. Overall, the study found that there was high exposure to 18 different HIV communication programmes (median 6 programmes and 14 programmes more than 30% across different age groups. Most programmes were more often seen or heard by young people aged between 15 and 24 years. In multivariate analysis, greater exposure to HIV mass communication programmes was associated with greater HIV knowledge, condom use at last sex, having tested for HIV in the past 12 months, and less stigmatizing attitude toward PLWHA.

    Full Text Available Due to the amplitude of the communication techniques in the public area in Western Countries and the spectacular development of publicity and public relations in this field, we find it interesting to analyze how and if this measure can be applied by Romanian public institutions and to Romanian public products. Thus, we discovered the sustained effort of the National Museum of Natural History “Grigore Antipa” (cultural nonprofit institution which delivers goods as public cultural products towards the entire nation’s population to promote itself and to communicate its activities to the public by using various techniques, both publicity and public relations, elaborating and creating exhibitions, conferences, festivals with interactive activities for the public, to involve him and transform him from a passive visitor of the museum into a participant at the cultural act. In 2003, the National Museum of Natural History “Grigore Antipa” from Bucharest began the implementation of an intense program of integrated marketing communication. The notion involves a strategic communication plan which uses more channels, addresses to various types of public and regards results achievement (cognitive, affective and behavior like – plan borrowed from the commercial area and applied in order to replace itself in the public’s mind, to achieve a larger exposure and to convince the public that, besides the scientific and educational role it plays, Antipa Museum offers also a relaxing way of spending free time.

    2012-06-01

    Full Text Available The research presented in this paper quantifies and models the impact of wet pavement surface and rainy weather conditions on driver perception-reaction times (PRTs, deceleration levels, and traffic signal change interval durations. A total of 648 stop-run records were collected as part of the research effort for a 72 km/h (45 mi/h approach speed where participant drivers encountered a yellow indication initiation at different distances from the intersection. The participant drivers were randomly selected in different age groups (under 40 years old, 40 to 59 years old, and 60 years of age or older and genders (female and male. Using the gathered data, statistical models for driver PRT and deceleration levels were developed, considering roadway surface and environmental parameters, driver attributes (age and gender, roadway grade, approaching speed, and time and distance to the intersection at the onset of yellow. Inclement weather yellow timings were then developed and summarized in lookup tables as a function of different factors (driver age/gender, roadway grade, speed limit, precipitation level, and roadway surface condition to provide practical guidelines for the design of yellow signal timings in wet and rainy weather conditions. The results indicate that wet roadway surface conditions require a 5 percent increase in the change interval and that rainy conditions require a 10 percent or more increase in the duration of the change interval. These recommended change durations can also be integrated within the Vehicle Infrastructure Integration (VII initiative to provide customizable driver warnings prior to a transition to a red indication.

  1. Quantifying the environmental impact of particulate deposition from dry unpaved roadways

    Energy Technology Data Exchange (ETDEWEB)

    Becker, D.L.

    1979-01-01

    Airborne dust is the air pollutant most frequently observed to exceed National Ambient Air Quality Standards in rural areas. This pollutant (also referred to as suspended particulates) may originate from point sources (e.g., large areas of bare soil or pollen-producing vegetation.) Most sources of atmospheric particulates, whether natural or anthropogenic, are difficult to quantify by means of a source strength (i.e., mass of particulates emitted per unit time). A numerical model was developed for calculating the source strength and quantifying the atmospheric transport and eposition of dust generated on unpaved roadways. This model satisfies the second-order differential equation for the diffusion process and also the equation of mass conservation. Input to the model includes meterological variables, surface roughness characteristics, and the size distribution and suspended particulate concentration of dust as sampled downwind of an unpaved roadway. By using predetermined tolerance levels of airborne concentrations or tolerance levels of deposition, maximum allowable vehicular traffic volume can be established. The model also may be used to estimate reduction in photosynthesis resulting from fugitive dust from point or line sources. The contribug ion to sedimentation in aquatic bodies, resulting from airborne particulates also may be assessed with this model.

    Full Text Available Indonesia is a nation with cultural diversity and area. This caused a lot of the uniqueness of culture in everyday life. This uniqueness was generally a positive value to maintain the harmony of human beings and nature. The discussion of this article was the verbal communication, the study of the wisdom of the nation speech-language Indonesia, and local wisdom in civilization. The words expressed in the local wisdom among others are fearless (need fear only God Almighty, self-sacrificing or spirit of nationalism (patriotism, orderly, loyal, affectionate, hardworking, consensus, mutual help, and creative. Positive values here needed to be crystallized in people’s lives; it would be the identifier of the Indonesian people. This research was conducted in five districts of Pagaralam, South Sumatra. The method used was qualitative. Data collection techniques included participant observer/observation, observation without participation, in-depth interviews, and documentation. This article finds that if local wisdom actually exists in everyday life, the nation of Indonesia has carved beauty behave in civilization itself. The local wisdom of the nation begins values, the rule in the family, and then developed in the community. A positive value of local wisdom is the identifier of civilized society and the need to preserve Indonesia.

    1997-09-01

    At the United Nations Conference on Environment and Development in Rio de Janeiro in June 1992 more than 150 countries signed the UN Framework Convention on Climate Change. According to decisions taken under article 12 of the Convention each developed country Party shall communicate to the Convention secretariat its second national report presenting inter-alia inventories of emissions by sources and removals by sinks of all greenhouse related gases. This report represents the Danish programmes and measures taken to observe the commitments under the Climate Convention. The revised 1996 IPCC guidelines have been applied to N 2 O from agriculture and the pollutants not earlier included (SO 2 , HFCs, CFCs and SF 6 ). Background material and data underlying the calculations in the report are available upon request to the Danish Environmental Protection Agency. A very comprehensive and thorough description is given of the programmes and plans for the energy sector with additional information presented in Annexes F and I. The twofold purpose is to give a detailed documentation of how Denmark will meet the ambitious target to reduce the emission of CO 2 by 20% by the year 2005 compared to 1988 and to inspire other Parties to the Convention in efforts to control their present as well as their future emissions of the most important greenhouse gases.

    Concern for the exposure of children attending schools located near busy roadways to toxic, traffic-related air pollutants has raised questions regarding the environmental benefits of advanced heating, ventilation, and air-conditioning (HVAC) filtration systems for near-road pollution. Levels of black carbon and gaseous pollutants were measured at three indoor classroom sites and at seven outdoor monitoring sites at Las Vegas schools. Initial HVAC filtration systems effected a 31-66% reduction in black carbon particle concentrations inside three schools compared with ambient air concentrations. After improved filtration systems were installed, black carbon particle concentrations were reduced by 74-97% inside three classrooms relative to ambient air concentrations. Average black carbon particle concentrations inside the schools with improved filtration systems were lower than typical ambient Las Vegas concentrations by 49-96%. Gaseous pollutants were higher indoors than outdoors. The higher indoor concentrations most likely originated at least partially from indoor sources, which were not targeted as part of this intervention. Recent literature has demonstrated adverse health effects in subjects exposed to ambient air near major roadways. Current smart growth planning and infill development often require that buildings such as schools are built near major roadways. Improving the filtration systems of a school's HVAC system was shown to decrease children's exposure to near-roadway diesel particulate matter. However, reducing exposure to the gas-phase air toxics, which primarily originated from indoor sources, may require multiple filter passes on recirculated air. © 2012 John Wiley & Sons A/S.

    Biological risk management in public health focuses on the impact of outbreaks on health, the economy, and other systems and on ensuring biosafety and biosecurity. To address this broad range of risks, the International Health Regulations (IHR, 2005) request that all member states build defined core capacities, risk communication being one of them. While there is existing guidance on the communication process and on what health authorities need to consider to design risk communication strategies that meet the requirements on a governance level, little has been done on implementation because of a number of factors, including lack of resources (human, financial, and others) and systems to support effective and consistent capacity for risk communication. The international conference on "Risk communication strategies before, during and after public health emergencies" provided a platform to present current strategies, facilitate learning from recent outbreaks of infectious diseases, and discuss recommendations to inform risk communication strategy development. The discussion concluded with 4 key areas for improvement in risk communication: consider communication as a multidimensional process in risk communication, broaden the biomedical paradigm by integrating social science intelligence into epidemiologic risk assessments, strengthen multisectoral collaboration including with local organizations, and spearhead changes in organizations for better risk communication governance. National strategies should design risk communication to be proactive, participatory, and multisectoral, facilitating the connection between sectors and strengthening collaboration.

    Communication disabilities, including speech, language and voice disabilities, can significantly impact a person's quality of life, employment and health status. Despite this, little is known about the prevalence and etiology of communication disabilities in the general adult population. To assess the prevalence and etiology of communication disabilities in a nationally representative adult sample. We conducted a cross-sectional study and analyzed the responses of non-institutionalized adults to the Sample Adult Core questionnaire within the 2012 National Health Interview Survey. We used respondents' self-report of having a speech, language or voice disability within the past year and receiving a diagnosis for one of these communication disabilities, as well as the etiology of their communication disability. We additionally examined the responses by subgroups, including sex, age, race and ethnicity, and geographical area. In 2012 approximately 10% of the US adult population reported a communication disability, while only 2% of adults reported receiving a diagnosis. The rates of speech, language and voice disabilities and diagnoses varied across gender, race/ethnicity and geographic groups. The most common response for the etiology of a communication disability was "something else." Improved understanding of population prevalence and etiologies of communication disabilities will assist in appropriately directing rehabilitation and medical services; potentially reducing the burden of communication disabilities.

    2014-01-01

    The National Aeronautics and Space Administration (NASA) Glenn Research Center (GRC) is investigating current and anticipated wireless communications concepts and technologies that the National Airspace System (NAS) may need in the next 50 years. NASA has awarded three NASA Research Announcements (NAR) studies with the objective to determine the most promising candidate technologies for air-to-air and air-to-ground data exchange and analyze their suitability in a post-NextGen NAS environment. This paper will present progress made in the studies and describe the communications challenges and opportunities that have been identified as part of the study. NASA's NextGen Concepts and Technology Development (CTD) Project integrates solutions for a safe, efficient and high-capacity airspace system through joint research efforts and partnerships with other government agencies. The CTD Project is one of two within NASA's Airspace Systems Program and is managed by the NASA Ames Research Center. Research within the CTD Project is in support the 2011 NASA Strategic Plan Sub-Goal 4.1: Develop innovative solutions and advanced technologies, through a balanced research portfolio, to improve current and future air transportation. The focus of CTD is on developing capabilities in traffic flow management, dynamic airspace configuration, separation assurance, super density operations and airport surface operations. Important to its research is the development of human/automation information requirements and decisionmaking guidelines for human-human and human-machine airportal decision-making. Airborne separation, oceanic intrail climb/descent and interval management applications depend on location and intent information of surrounding aircraft. ADS-B has been proposed to provide the information exchange, but other candidates such as satellite-based receivers, broadband or airborne internet, and cellular communications are possible candidate's.

    Improving the quality of physicians' recommendations for human papillomavirus (HPV) vaccination is critical to addressing low coverage. Thus, we sought to describe HPV vaccine communication practices among primary care physicians. Pediatricians and family physicians (n = 776) completed our national online survey in 2014. We assessed the quality of their HPV vaccine recommendations on strength of endorsement (i.e., saying the vaccine is important), timeliness (recommending it by ages 11-12), consistency (recommending it routinely vs. using a risk-based approach), and urgency (recommending same-day vaccination). A sizeable minority of physicians reported that they do not strongly endorse HPV vaccine (27%) or deliver timely recommendations for girls (26%) or boys (39%). Many physicians (59%) used a risk-based approach to recommending HPV vaccine, and only half (51%) usually recommended same-day vaccination. Overall recommendation quality was lower among physicians who were uncomfortable talking about HPV vaccine or who believed parents did not value it. Quality was higher among physicians who began discussions by saying the child was due for HPV vaccine versus giving information or eliciting questions. Many physicians in our national sample reported recommending HPV vaccine inconsistently, behind schedule, or without urgency. These practices likely contribute to under-immunization among adolescents, and may convey ambivalence to parents. As one of the first studies to assess multiple aspects of recommendation quality, these findings can inform the many state and national initiatives that aim to improve communication about HPV vaccine so as to address the persistent underuse of a powerful tool for cancer prevention. ©2015 American Association for Cancer Research.

  13. The National Bank of Ukraine Communication Strategy Optimization within the Framework of Impact on Exchange Rate Expectations of Economic Agents

    Directory of Open Access Journals (Sweden)

    Roksolana Holub

    2017-09-01

    Full Text Available An important challenge in terms of smoothing excessive exchange rate volatility under the conditions of flexible exchange rate arrangement is optimization of the communication strategy of the country’s monetary regulator. Over the past two decades, communication (information support has become an increasingly important aspect of monetary policy. Communication enables influence of the volatility of financial markets, improvement of the predictability of monetary policy, and helps to achieve macroeconomic objectives. Nevertheless, as of today, consensus on the issue into what the optimal strategy of the central bank communication is has not been reached, either in Ukraine, nor in developed countries yet. Considering the abovementioned, the methodical approaches to improve the central bank’s communication strategies, based on the use of its verbal interventions in the context of smoothing out excessive cyclical volatility of exchange rates of the national currency, are determined in this article. It is suggested to consider the growth of the factor “information signal/information noise” as a criterion of the central bank’s optimal communication strategy. It is proved that the monetary regulator’s main task should be the continual provision of information concerning a fundamentally justified level of the exchange rate and the level of deviation of the actual rate of the national currency from its fundamental-equilibrium level, as of a given time, to the national foreign exchange market participants. The methodological approach to the improvement of information support of forecasting fundamentally specified value of the national currency is outlined.

    The British Geological Survey (BGS) is the national geological agency for Great Britain that provides geoscientific information to government, other institutions and the public. The National Landslide Database has been developed by the BGS and is the focus for national geohazard research for landslides in Great Britain. The history and structure of the geospatial database and associated Geographical Information System (GIS) are explained, along with the future developments of the database and its applications. The database is the most extensive source of information on landslides in Great Britain with over 17,000 records of landslide events to date, each documented as fully as possible for inland, coastal and artificial slopes. Data are gathered through a range of procedures, including: incorporation of other databases; automated trawling of current and historical scientific literature and media reports; new field- and desk-based mapping technologies with digital data capture, and using citizen science through social media and other online resources. This information is invaluable for directing the investigation, prevention and mitigation of areas of unstable ground in accordance with Government planning policy guidelines. The national landslide susceptibility map (GeoSure) and a national landslide domains map currently under development, as well as regional mapping campaigns, rely heavily on the information contained within the landslide database. Assessing susceptibility to landsliding requires knowledge of the distribution of failures, an understanding of causative factors, their spatial distribution and likely impacts, whilst understanding the frequency and types of landsliding present is integral to modelling how rainfall will influence the stability of a region. Communication of landslide data through the Natural Hazard Partnership (NHP) and Hazard Impact Model contributes to national hazard mitigation and disaster risk reduction with respect to weather and

    Full Text Available Abstract Background Most patients contact their general practitioner (GP following presentation to an Emergency Department (ED after a self-harm incident, and strategies to help GPs manage these patients include efficient communication between services. The aim of this study was to assess the standard of documentation and communication to primary care from secondary care as recommended by the National Institute of Clinical Excellence (NICE guidelines on the short-term management of people who self-harm. Methods An audit of medical records (ED and Psychiatric on people aged 16 years and over who had presented to the ED following self-harm, benchmarked according to government guidelines, was performed. Data were collected over a 4-week period at a general teaching hospital. Results We collected data on 93 consecutive episodes of self-harm; 62% of episodes were communicated to primary care, 58% of these communications were within 24 h and most within 3 days. Patient identifying details and follow-up arrangements were specified in most cases. Communication via psychiatric staff was most detailed. ED clinicians provided few communications and were of limited content. Communication with the patient's GP was not made in half of those cases seen by a mental health specialist. Conclusion Government guidelines are only partially being met. Reliance on communication by ED staff would leave a substantial proportion of patients discharged from the ED with no or minimal communication to primary care. Psychiatric services need to improve the rate of communication to the patient's GP following assessment A national sample of National Health Service (NHS trusts would establish if this is a problem elsewhere.

  16. Analyzing Potential Grid Impacts from Future In-Motion Roadway Wireless Power Transfer Scenarios: Preprint

    This work examines the grid impact of in-motion roadway wireless power transfer through the examination of the electrification of high-capacity roadways inside a metropolitan area. The work uses data from a regional travel study and the Federal Highway Administration's Highway Performance Monitoring System to estimate the electrified roadway's hourly power use throughout a week. The data are then combined with hourly grid load estimates for the same metropolitan area to determine the overlay of traditional grid load with additional load from a future electrified roadway.

    2010-09-01

    The purpose of this work was to determine if public communication of science and technology (PCST) has any influence on people's decision to become dedicated to scientific research. For this reason, a national survey involving 852 researchers from all disciplines was conducted in Argentina. The results showed that the factors affecting scientific vocation are many, and that, regardless of differences in gender, age or discipline, the greatest influence on the decision to go into scientific research is exerted by teachers. The analysis also demonstrated that different manifestations of PCST (science books, press articles, audiovisual material, and activities such as visits to science museums) play a significant role in awakening the vocation for science. From these results it may be stated that PCST--in addition to its function of informing and forming citizens--exerts a significant influence in fostering scientific vocation.

    Indoor tanning is a risk factor for melanoma among young white women. Health communications can be an effective way of reaching this population and promoting behavior change. The purpose of this study was (i) to investigate the associations between intention to quit indoor tanning and attitudes, normative pressure, and efficacy about quitting, and (ii) to identify beliefs about quitting indoor tanning that can be used to design effective health communication messages to reduce skin cancer risk. A national online survey was conducted with 279 non-Hispanic white women ages 18-25 in the USA who are indoor tanners. The survey, based on the reasoned action approach, assessed intention, attitudes, norms, and efficacy and their corresponding underlying beliefs related to quitting indoor tanning, along with other known covariates. Data were collected in November/December 2015. Intention to quit indoor tanning was significantly associated with attitudes, specifically with the beliefs that it would "reduce damage to skin" (increased intention) and "make me less happy" (decreased intention). While self-efficacy was not related to intention to quit indoor tanning, injunctive normative beliefs were with key referent groups including mothers, friends, and romantic partners. Messages aimed at discouraging indoor tanning among young, non-Hispanic, white women should highlight the salient belief that quitting indoor tanning will reduce skin damage, counter the belief that it will make them less happy, and highlight key people who would approve of them quitting indoor tanning.

    Clinical trials are essential for developing new and effective treatments and improving patient quality of life; however, many trials cannot answer their primary research questions because they fall short of their recruitment goals. This article reports the results of formative research conducted in two populations, the public and primary care physicians, to identify messages that may raise awareness and increase interest in clinical trials and be used in a national communication campaign. Results suggested that participants were primarily motivated to participate in clinical trials out of a self-interest to help themselves first. Messages illustrated that current treatments were tested via clinical trials, helped normalize trials as routine practices, and reduced concerns over trying something new first. Participants wanted messages that portray trials as state-of-the-art choices that offer some hope, show people like themselves, and are described in a clear, concise manner with actionable steps for them to take. The study revealed some differences in message salience, with healthy audiences exhibiting lower levels of interest. Our results suggest that targeted messages are needed, and that communication with primary health-care providers is an important and necessary component in raising patient awareness of the importance of clinical trials.

    1978-05-01

    One of the objectives of the National Waste Terminal Storage (NWTS) Program is to provide terminal storage facilities for commercial radioactive wastes in various geologic formations at multiple locations in the United States. The activities performed under the NWTS Program will affect regional, state, and local areas, and widespread public interest in this program is expected. Since a large part of the NWTS Program deals with technical information it was considered desirable to initiate a study dealing with possible methods of effectively transmitting this technical information to the general public. This study has the objective of preparing a state-of-the-art report on the communication of technical information to lay audiences. The particular task of communicating information about the NWTS Program to the public is discussed where appropriate. The results of this study will aid the NWTS Program in presenting to the public the quite diverse technical information generated within the program so that a widespread, thorough public understanding of the NWTS Program might be achieved. An annotated bibliography is included.

    2013-06-01

    A survey was conducted to assess trainee perception of the cross-cultural communication competency of U.S. military trainers and their satisfaction with the training they received. Findings from the survey show that U.S. military trainers rely significantly on local interpreters. This indicates variability in the ability of the trainers to communicate effectively with host nation partners, the variability being dependent on the capabilities of the individual interpreter. The findings illustrate the importance of providing military health personnel with training on how to work effectively with interpreters. The use of supplementary resources such as electronic translation devises when the interpreter is not capable of conveying health-related training information with the desired level of accuracy is recommended. Expanding the availability of general cultural training, which provides baseline information on local values, traditions, and customs in addition to health-specific cultural orientation, is also recommended to help military health trainers customize their training content and methods to fit the local environment.

    Understanding the health of our planet on a global scale is essential to the world’s populace. Earth-observing satellites have long been collecting data that enable a robust comprehension of Earth’s complex and interconnected systems. Despite these important contributions, the fleet of U.S. Earth-observing satellites is aging and operational status for most onboard sensors has not materialized. These satellites are imperative objective viewers of our changing planet as we try to monitor and deal with natural disasters, carbon budgeting, water consumption, and food production. But the satellite building and launching process needed to sustain an operational observatory is extremely political. Landsat, the oldest civilian land-observing satellite, has a long and checkered political past, and it is only because of a handful of political champions that the program has endured. This begs the question: are policymakers aware of the contributions of satellites to our national wellbeing? And if not, can the science community better communicate with the general public at large and policy makers in particular? Here Landsat is examined as a political entity and the six pillars of effective science communication (context, trust, dialogue, clarity, respect, nuance) are used to develop, refine, and analyze a fact sheet and case study that explain the importance of Landsat Earth-observation to our society.

  4. National disease management plans for key chronic non-communicable diseases in Singapore.

    2002-07-01

    In Singapore, chronic, non-communicable diseases, namely coronary heart disease, stroke and cancer, account for more than 60% of all deaths and a high burden of disability and healthcare expenditure. The burden of these diseases is likely to rise with our rapidly ageing population and changing lifestyles, and will present profound challenges to our healthcare delivery and financing systems over the next 20 to 30 years. The containment and optimal management of these conditions require a strong emphasis on patient education and the development of integrated models of healthcare delivery in place of the present uncoordinated, compartmentalised way of delivering healthcare. To meet these challenges, the Ministry of Health's major thrusts are disease control measures which focus mainly on primary prevention; and disease management, which coordinates the national effort to reduce the incidence of these key diseases and their predisposing factors and to ameliorate their long-term impact by optimising control to reduce mortality, morbidity and complications, and improving functional status through rehabilitation. The key initiatives include restructuring of the public sector healthcare institutions into two clusters, each comprising a network of primary health care polyclinics, regional hospitals and tertiary institutions. The functional integration of these healthcare elements within each cluster under a common senior administrative and professional management, and the development of common clinical IT systems will greatly facilitate the implementation of disease management programmes. Secondly, the Ministry is establishing National Disease Registries in coronary heart disease, cancer, stroke, myopia and kidney failure, which will be valuable sources of clinical and outcomes data. Thirdly, in partnership with expert groups, national committees and professional agencies, the Ministry will produce clinical practice guidelines which will assist doctors and healthcare

    2016-01-01

    Full Text Available Based on the mining practice in an extremely close coal seam, theoretical analysis was conducted on the vertical stress distribution of the floor strata under a large coal pillar. The vertical stress distribution regulation of a No. 5 coal seam was revealed. To obtain the optimum position of the roadway that bears the supporting pressure of a large coal pillar, numerical modeling was applied to analyze the relation among the stress distribution of the roadway surrounding the rock that bears the supporting pressure of a large coal pillar, the plastic zone distribution of the roadway surrounding the rock, the surrounding rock deformation, and the roadway layout position. The theoretical calculation results of the stress value, stress variation rate, and influencing range of the stress influencing angle showed that the reasonable malposition of the No. 5 coal seam roadway was an inner malposition of 4 m. The mining practice showed the following: the layout of No. 25301 panel belt roadway at the position of the inner malposition of 4 m was reasonable, the roadway support performance was favourable without deformation, and ground pressure was not obvious. The research achievement of this study is the provision of a reference for roadway layouts under similar conditions.

    2014-03-01

    According to the 2013 ASCE report card America's infrastructure scores only a D+. There are more than four million miles of roads (grade D) in the U.S. requiring a broad range of maintenance activities. The nation faces a monumental problem of infrastructure management in the scheduling and implementation of maintenance and repair operations, and in the prioritization of expenditures within budgetary constraints. The efficient and effective performance of these operations however is crucial to ensuring roadway safety, preventing catastrophic failures, and promoting economic growth. There is a critical need for technology that can cost-effectively monitor the condition of a network-wide road system and provide accurate, up-to-date information for maintenance activity prioritization. The Versatile Onboard Traffic Embedded Roaming Sensors (VOTERS) project provides a framework and the sensing capability to complement periodical localized inspections to continuous network-wide health monitoring. Research focused on the development of a cost-effective, lightweight package of multi-modal sensor systems compatible with this framework. An innovative software infrastructure is created that collects, processes, and evaluates these large time-lapse multi-modal data streams. A GIS-based control center manages multiple inspection vehicles and the data for further analysis, visualization, and decision making. VOTERS' technology can monitor road conditions at both the surface and sub-surface levels while the vehicle is navigating through daily traffic going about its normal business, thereby allowing for network-wide frequent assessment of roadways. This deterioration process monitoring at unprecedented time and spatial scales provides unique experimental data that can be used to improve life-cycle cost analysis models.

  10. Wind tunnel modeling of roadways: Comparison with mathematical models

    The assessment of air quality impacts from roadways is a major concern to urban planners. In order to assess future road and building configurations, a number of techniques have been developed including mathematical models, which simulate traffic emissions and atmospheric dispersion through a series of mathematical relationships and physical models. The latter models simulate emissions and dispersion through scaling of these processes in a wind tunnel. Two roadway mathematical models, HIWAY-2 and CALINE-4, were applied to a proposed development in a large urban area. Physical modeling procedures developed by Rowan Williams Davies and Irwin Inc. (RWDI) in the form of line source simulators were also applied, and the resulting carbon monoxide concentrations were compared. The results indicated a factor of two agreement between the mathematical and physical models. The physical model, however, reacted to change in building massing and configuration. The mathematical models did not, since no provision for such changes was included in the mathematical models. In general, the RWDI model resulted in higher concentrations than either HIWAY-2 or CALINE-4. Where there was underprediction, it was often due to shielding of the receptor by surrounding buildings. Comparison of these three models with the CALTRANS Tracer Dispersion Experiment showed good results although concentrations were consistently underpredicted

  11. Experimental Study on Shear Performance of Bolt in Roadway Supporting

    Full Text Available The corner bolt is proved to be effective in the control of floor deformation of roadway, and the relevant studies on bolting mechanisms are of great significance in improving roadway stability. In this paper, two types of shear tests on six forms of bolts are performed by using self-designed shear test device, the electro-hydraulic servo triaxial testing system. The shear characteristics of different types of bolts are obtained. The results show that different bolt rods or different internal filling conditions result in large differences in shear resistance and different deformation adaptability. We find that the filling materials added can improve the shear performance of bolt significantly, and the bolt with steel not only can improve the strength of bolt body, but also has the bimodal characteristic that makes the bolt have the secondary bearing capacity and withstand larger deformation range during the process of shear, and shows a better support performance. Hoping to provide the experiment basis for support design and field application in the future.

    Using sense of place can help scientists improve their communication of complex concepts related to the connectivity of the environment, geological processes, and human societies. National parks afford excellent examples of places that contain intellectual and emotional stimuli for diverse individuals - in other words, they foster a sense of place. Parks contain spectacular examples of how the processes that shape the earth influence ecosystem and societal development. Parks can therefore be used as outdoor classrooms to engage people in place-based Earth Science education. Incorporating place-based teaching methods can promote learning about Earth’s processes that ensures that a wider audience can be reached than by traditional instructional methods. Specific examples of using national parks on the Colorado Plateau, in the Rocky Mountains and the Keweenaw Peninsula for K-12 teacher training have resulted in a deepening of Earth Science content-area knowledge. The National Parks “Views of the National Park (Views)” multimedia education program can subsequently be used to promote engagement of students in the teachers’ classrooms. Teachers who wish to continue their education as interns in the parks are served by programs such as Geoscientists-in-the-Parks, Volunteers-in-Parks, and Teacher-Ranger-Teacher programs. The Michigan Teaching Excellence Program (MiTEP), multi-year teacher leadership and professional development program is working with middle-grade science teachers from selected urban districts and using the parks of the Midwest as natural classrooms. MiTEP has partnered with the NPS to develop internship opportunities for teachers in the parks. These internships will result in educational materials that can be hosted by “Views”. The goal of the internships are to improve teachers’ understanding of the natural environment and the processes that it reflects, and to assist park personnel in producing materials that are standards-based, age

  15. Impact of Roadway Stormwater Runoff on Microbial Contamination in the Receiving Stream.

    Stormwater runoff from roadways has increasingly become a regulatory concern for water pollution control. Recent work has suggested roadway stormwater runoff as a potential source of microbial pollutants. The objective of this study was to determine the impact of roadway runoff on the microbiological quality of receiving streams. Microbiological quality of roadway stormwater runoff and the receiving stream was monitored during storm events with both cultivation-dependent fecal bacteria enumeration and cultivation-independent high-throughput sequencing techniques. Enumeration of total coliforms as a measure of fecal microbial pollution found consistently lower total coliform counts in roadway runoff than those in the stream water, suggesting that roadway runoff was not a major contributor of microbial pollutants to the receiving stream. Further characterization of the microbial community in the stormwater samples by 16S ribosomal RNA gene-based high-throughput amplicon sequencing revealed significant differences in the microbial composition of stormwater runoff from the roadways and the receiving stream. The differences in microbial composition between the roadway runoff and stream water demonstrate that roadway runoff did not appear to have a major influence on the stream in terms of microbiological quality. Thus, results from both fecal bacteria enumeration and high-throughput amplicon sequencing techniques were consistent that roadway stormwater runoff was not the primary contributor of microbial loading to the stream. Further studies of additional watersheds with distinct characteristics are needed to validate these findings. Understanding gained in this study could support the development of more effective strategies for stormwater management in sensitive watersheds.

  19. How Does Difficulty Communicating Affect the Social Relationships of Older Adults? An Exploration Using Data from a National Survey

    2016-01-01

    Healthy social relationships are important for maintaining mental and physical health in later life. Less social support, smaller social networks, and more negative social interactions have been linked to depression, poorer immune functioning, lower self-rated health, increased incidence of disease, and higher mortality. Overwhelming evidence suggests that communication disorders adversely affect social relationships. Much less is known about whether some or all aspects of social relationships are negatively affected by a communication disorder. The relative impact of a communication disorder on social relationships, as compared to other kinds of disability, is also poorly understood. Data were analyzed from a representative national sample of community-dwelling adults aged 65 and older living in the continental United States (n = 742). Results from multiple regressions indicated that difficulty communicating was significantly associated with several parameters of social relationships even after controlling for age, gender, partnership status, health, functional limitations, and visual impairment. Communication difficulty was a significant predictor of smaller social network size, fewer positive social exchanges, less frequent participation in social activities, and higher levels of loneliness, but was not a significant predictor of negative social exchanges. These findings suggest that communication disorders may place older adults at increased risk for mental and physical health problems because of social isolation, reduced social participation, and higher rates of loneliness. In addition, it appears that communication disorders may have a greater impact on positive, rather than negative, aspects of social relationships. PMID:27420152

    Boudet, H. S.

    2013-12-01

    The recent push to develop unconventional sources of oil and gas both in the U.S. and abroad via hydraulic fracturing ('fracking') has generated a great deal of controversy. Effectively engaging stakeholders and setting appropriate policies requires insights into current public perceptions of this issue. Using a nationally representative U.S. sample (N=1,061), we examine public perceptions of hydraulic fracturing including: 'top of mind' associations; familiarity with the issue; levels of support/opposition; and predictors of such judgments. Similar to findings on other emerging technologies, our results suggest limited familiarity with the process and its potential impacts and considerable uncertainty about whether to support it. Multiple regression analysis (r2 = 0.49) finds that women, those holding egalitarian worldviews, those who read newspapers more than once a week, those more familiar with hydraulic fracturing, and those who associate the process with environmental impacts are more likely to oppose fracking. In contrast, people more likely to support fracking tend to be older, hold a bachelor's degree or higher, politically conservative, watch TV news more than once a week, and associate the process with positive economic or energy supply outcomes. Based on these findings, we discuss recommendations for future research, risk communication, and energy policy.

    Today the ICTs are favourable additions to museum exhibitions. This work aims to realize an innovative system of digital exploitation of artefacts in the National Archaeological Museum of Marche (MANaM), in order to create a shared museum that will improve the knowledge of cultural contents through the paradigm "learning by interacting" and "edutainment". The main novelty is the implementation of stand-alone multimedia installations for digital artefacts that combine real and virtual scenarios in order to enrich the experience, the knowledge and the multi-sensory perception. A Digital Library (DL) is created using Close Range Photogrammetry (CRP) techniques applied to 21 archaeological artefacts belonging to different categories. Enriched with other data (texts, images, multimedia), all 3D models flow into the cloud data server from which are recalled in the individual exhibitions. In particular, we have chosen three types of technological solutions: VISUAL, TACTILE, SPATIAL. All the solutions take into account the possibility of group interaction, allowing the participation of the interaction to an appropriate number of users. Sharing the experience enables greater involvement, generating communicative effectiveness much higher than it would get from a lonely visit. From the "Museum Visitors Behaviour Analysis" we obtain a survey about users' needs and efficiency of the interactive solutions. The main result of this work is the educational impact in terms of increase in visitors, specially students, learning increase of historical and cultural content, greater user involvement during the visit to the museum.

    1988-01-01

    The trend in modern mass communication appears to be toward the imposition of the cultural, economic, and political values of the societies with the most advanced communication and information technologies and media sources. The consequence of this reality is that the cultural values, national aspirations, economic needs, and political independence of developing countries are not taken into consideration. Thus, the national interests of African states make it imperative for them to carefully evaluate, assess, and examine the development of their present media structures and ownership patterns. If the mass media is privatized, their owners serve as mouthpieces for multinational corporations. This phenomenon can severely undermine African goals of self-sufficiency in food production and industrialization, political stability that guarantees territorial integrity, and preservation of the African culture. It is imperative that African governments do not allow big multinationals to take over the molding and control of public opinion. Although modern systems of communication are exceedingly expensive and sophisticated, ways must be found to make the media public utilities.

  11. A Study of the Large Deformation Mechanism and Control Techniques for Deep Soft Rock Roadways

    2018-04-01

    Full Text Available Large deformation control of deep soft rock roadways has been a major problem in mining activities worldwide. This paper considers the supporting problem related to large deformation of a deep soft rock roadway in Chao’hua coal mine. The discrete element simulation method (UDEC software is adopted to simulate a tailgate of panel 31041 in Chao’hua coal mine. The failure patterns of unsupported and primary supported roadway are simulated, and these reveal the characteristics of deformation, stress and crack propagation. The excavation of roadway leads to high deviator stress, which exceeds the peak strength of shallow surrounding rock and causes it to enter the post-failure stage. Tensile failures then initiate and develop around the roadway, which causes the fragmentation, dilation and separation of shallow surrounding rock. The compressive capacity of the primary support system is low, which results in serious contraction in the full section of the roadway. An improved control scheme is put forward for the support of a tailgate. The underground test results confirm that the improved support system effectively controlled large deformation of the surrounding rocks, which can provide references for support in the design of roadways excavated in deep soft stratum.

    The aim of this study was to compare student nurses' communication self-efficacy, empathy, and mindfulness across two countries, and to analyse the relationship between these qualities. The study had a cross-sectional design. Data was collected from final year student nurses in Norway and Sweden. Communication self-efficacy, empathy, and mindfulness were reported by questionnaires; Clear-cut communication with patients, Jefferson Scale of Empathy, and Langer 14 items mindfulness scale. The study included 156 student nurses, 94 (60%) were Swedish. The mean communication self-efficacy score was 119 (95% CI 116-122), empathy score 115 (95% CI 113-117) and mindfulness score 79 (95% CI 78-81). A Mann-Whitney test showed that Swedish students scored significantly higher on communication self-efficacy, empathy, and mindfulness than Norwegian students did. When adjusted for age, gender, and country in a multiple linear regression, mindfulness was the only independent predictor of communication self-efficacy. The Swedish student nurses in this study scored higher on communication self-efficacy, empathy, and mindfulness than Norwegian students did. Student nurses scoring high on mindfulness rated their communication self-efficacy higher. A mindful learning approach may improve communication self-efficacy and possibly the effect of communication skills training. Copyright © 2017 Elsevier B.V. All rights reserved.

    Good communication skills and rapport building are considered the cardinal tools for developing a patient-doctor relationship. A positive, healthy competition among different health care organizations in Saudi Arabia underlines an ever increasing emphasis on effective patient-doctor relationship. Despite the numerous guidelines provided and programs available, there is a significant variation in the acceptance and approach to the use of this important tool among pediatric residents in this part of the world. To determine pediatric residents' attitude toward communication skills, their perception of important communication skills, and their confidence in the use of their communication skills in the performance of their primary duties. A cross-sectional study was conducted among all pediatrics trainee residents working in 13 different hospitals in Saudi Arabia. A standardized self-administered questionnaire developed by the Harvard Medical School was used. A total of 297 residents out of all trainees in these centers participated in the data collection. The 283 (95%) residents considered learning communication skills a priority in establishing a good patient-doctor relationship. Thirty four percent reported being very confident with regard to their communication skills. Few residents had the skills, and the confidence to communicate with children with serious diseases, discuss end-of-life issues, and deal with difficult patients and parents. Pediatric residents perceive the importance of communication skills and competencies as crucial components in their training. A proper comprehensive communication skills training should be incorporated into the pediatric resident training curriculum.

    Despite the benefits of improving transitions across care, literature is very limited on inpatient "Communication about Medicines" (ComMed) by staff across United States (U.S.) hospitals. To evaluate ComMed quality variations by hospital characteristics. In a cross-sectional, retrospective study of publicly available U.S. Medicare's Hospital Consumer Assessment of Health Care Plans Survey (HCAHPS) data (January 2013-September 2014), ComMed quality (high = above average/excellent vs. low = average/below average/poor star ratings) of 3125 hospitals were compared across region, rural-urban location, and health information technology (HIT) infrastructure giving providers access to patients' electronic medical records. Multivariate logistic regression analysis was conducted with adjusting for confounders (hospital - bed size, ownership, type, ED services, the number of completed HCAHPS surveys). After adjusting for other characteristics, Midwest versus Western region hospitals (OR = 1.55, 95% CI: 1.21-1.98, p=quality. Hospitals' small bed-size, physician/non-profit ownership, critical-access type, absent ED services, and 100-299 HCAHPS completed surveys were more likely to be associated with high ComMed quality. One of the first national studies found significant variations in ComMed quality across U.S. hospitals by location (high in Midwest and low in Northeast regions and urban areas) and by access to HIT infrastructure (high) after controlling for other hospital characteristics. With this baseline data, hospital providers and policymakers can design, implement, and evaluate service programs with pharmacists and HIT to enhance ComMed quality in the future delivery of patient-centered care.

    McFarland, Daniel C; Johnson Shen, Megan; Holcombe, Randall F

    2017-10-01

    Prior research indicates that effective communication between medical providers and patients is associated with a number of positive patient outcomes, yet little research has examined how ecological factors (e.g., hospital size, local demographics) influence patients' reported satisfaction with doctor and nurse communication. Given the current emphasis on improving patient satisfaction in hospitals across the United States, understanding these factors is critical to interpreting patient satisfaction and improving patient-centered communication, particularly in diverse and dense populations. As such, this study examined county-level data including population density, population diversity, and hospital structural factors as predictors of patient satisfaction with doctor and nurse communication. Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS), U.S. Census data, and number of hospital beds were obtained from publicly available Hospital Compare, U.S. Census, and American Hospital Directory websites, respectively. Multivariate regression modeling was performed for the individual dimensions of HCAHPS scores assessing doctor and nurse communication. Standardized partial regression coefficients were used to assess strengths of county-level predictors. County-level factors accounted for 30% and 16% of variability in patient satisfaction with doctor and nurse communication, respectively. College education (β = 0.45) and White ethnicity (β = 0.25) most strongly predicted a favorable rating of doctor and nurse communication, respectively. Primary language (non-English speaking; β = -0.50) most strongly predicted an unfavorable rating of doctor communication, while number of hospital beds (β = -0.16) and foreign-born (β = -0.16) most strongly predicted an unfavorable rating of nurse communication. County-level predictors should be considered when interpreting patient satisfaction with doctor and nurse communication and designing

    Communication campaigns are an accepted method for altering societal attitudes, increasing knowledge, and achieving social and behavioral change particularly within public health and the social sciences. The Image Gently(SM) campaign is a national education and awareness campaign in radiology designed to promote the need for and opportunities to decrease radiation to children when CT scans are indicated. In this article, the relatively new science of social marketing is reviewed and the theoretical basis for an effective communication campaign in radiology is discussed. Communication strategies are considered and the type of outcomes that should be measured are reviewed. This methodology has demonstrated that simple, straightforward safety messages on radiation protection targeted to medical professionals throughout the radiology community, utilizing multiple media, can affect awareness potentially leading to change in practice.

    Objective: To assess the implementation and impact of programs carried out by the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases. Methods: Both sociological and epidemiological methods were used to collect qualitative and quantitative data in November and December, 2016 in order to conduct on process and outcome evaluation of the above mentioned objective. In the meantime, case study was also conducted. Results: All the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases were found well implemented across the country, with health education and health promotion, surveillance and safeguard measures in particular. A government-led and inter-sector coordination and communication mechanism had been well established, with more than 16 non-health departments actively involved. 28.7% of the residents living in the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases were aware of the key messages related to chronic diseases. Among the residents, 72.1% of them consumed vegetables and 53.6% consumed fruits daily, with another 86.9% walked at least 10 minutes per day. Over 70% of the patients with hypertension or diabetes reported that they were taken care of by the Community Health Centers, and above 50% of them were under standardized management. Residents, living in the National Demonstration Areas under higher ranking of implementation scores, were more likely to be aware of relevant knowledge on chronic disease control and prevention ( OR =6.591, 95% CI : 5.188-8.373), salt reduction ( OR =1.352, 95% CI : 1.151-1.589), oil reduction ( OR =1.477, 95% CI : 1.249-1.746) and recommendation on physical activities ( OR =1.975, 95% CI : 1.623- 2.403). Conclusion: The implementation of programs carried out by the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases had served a local

    Sexual communication is a principal means of transmitting sexual values, beliefs, expectations, and knowledge from parents to children. Although this area has received considerable research attention, more studies with representative samples are needed to assure that findings are reflective of populations of interest. A nationally representative sample of parent-adolescent dyads (N = 2,965; mean adolescent age = 13.8 years) in the Netherlands was employed to examine the frequency of parent-adolescent sexual communication and its association with adolescent sexual behaviors (defined as sexual initiation, condom use, and contraceptive pill use). Nine communication topics in the areas of anatomy, relationships and rights, and protection and contraception were examined. In all, 75%of parents reported having discussed at least one topic multiple times with their adolescents. Romantic relationships were discussed most frequently. Hierarchical logistic regression analyses indicated that parent-adolescent sexual communication on protection and contraception was positively associated with adolescent sexual initiation and contraceptive pill use but not condom use. This may reflect that adolescents, when they become sexually active, are more likely to discuss sexuality with their parents. Findings are interpreted within the context of Dutch culture, which is generally accepting of adolescent sexuality and characterized by open sexual communication.

    2015-10-01

    Full Text Available To effectively improve the climate conditions of the excavation roadway in coal mine, the calculation of the chilling requirement taking air conditioning measures is extremely necessary. The temperature field of the surrounding rock with moving boundary in the excavation roadway was numerically simulated by using finite volume method. The unstable heat transfer coefficient between the surrounding rock and air flow was obtained via the previous calculation. According to the coupling effects of the air flow inside and outside air duct, the differential calculation mathematical model of air flow temperature in the excavation roadway was established. The chilling requirement was calculated with the selfdeveloped computer program for forecasting the required cooling capacity of the excavation roadway. A good air conditioning effect had been observed after applying the calculated results to field trial, which indicated that the prediction method and calculation procedure were reliable.

    Full Text Available Background: Good communication skills and rapport building are considered the cardinal tools for developing a patient-doctor relationship. A positive, healthy competition among different health care organizations in Saudi Arabia underlines an ever increasing emphasis on effective patient-doctor relationship. Despite the numerous guidelines provided and programs available, there is a significant variation in the acceptance and approach to the use of this important tool among pediatric residents in this part of the world. Objective: To determine pediatric residents′ attitude toward communication skills, their perception of important communication skills, and their confidence in the use of their communication skills in the performance of their primary duties. Materials and Methods: A cross-sectional study was conducted among all pediatrics trainee residents working in 13 different hospitals in Saudi Arabia. A standardized self-administered questionnaire developed by the Harvard Medical School was used. Results: A total of 297 residents out of all trainees in these centers participated in the data collection. The 283 (95% residents considered learning communication skills a priority in establishing a good patient-doctor relationship. Thirty four percent reported being very confident with regard to their communication skills. Few residents had the skills, and the confidence to communicate with children with serious diseases, discuss end-of-life issues, and deal with difficult patients and parents. Conclusion: Pediatric residents perceive the importance of communication skills and competencies as crucial components in their training. A proper comprehensive communication skills training should be incorporated into the pediatric resident training curriculum.

    Clements, Andrea L.; Jia, Yuling; Denbleyker, Allison; McDonald-Buller, Elena; Fraser, Matthew P.; Allen, David T.; Collins, Donald R.; Michel, Edward; Pudota, Jayanth; Sullivan, David; Zhu, Yifang

    Spatial gradients of vehicular emitted air pollutants were measured in the vicinity of three roadways in the Austin, Texas area: (1) State Highway 71 (SH-71), a heavily traveled arterial highway dominated by passenger vehicles; (2) Interstate 35 (I-35), a limited access highway north of Austin in Georgetown; and (3) Farm to Market Road 973 (FM-973), a heavily traveled surface roadway with significant truck traffic. A mobile monitoring platform was used to characterize the gradients of CO and NO x concentrations with increased distance from each roadway, while concentrations of carbonyls in the gas-phase and fine particulate matter mass and composition were measured at stationary sites upwind and at one (I-35 and FM-973) or two (SH-71) downwind sites. Regardless of roadway type or wind direction, concentrations of carbon monoxide (CO), nitric oxide (NO), and oxides of nitrogen (NO x) returned to background levels within a few hundred meters of the roadway. Under perpendicular wind conditions, CO, NO and NO x concentrations decreased exponentially with increasing distance perpendicular to the roadways. The decay rate for NO was more than a factor of two greater than for CO, and it comprised a larger fraction of NO x closer to the roadways than further downwind suggesting the potential significance of near roadway chemical processing as well as atmospheric dilution. Concentrations of most carbonyl species decreased with distance downwind of SH-71. However, concentrations of acetaldehyde and acrolein increased farther downwind of SH-71, suggesting chemical generation from the oxidation of primary vehicular emissions. The behavior of particle-bound organic species was complex and further investigation of the size-segregated chemical composition of particulate matter (PM) at increasing downwind distances from roadways is warranted. Fine particulate matter (PM 2.5) mass concentrations, polycyclic aromatic hydrocarbons (PAHs), hopanes, and elemental carbon (EC

    Many proponents of gas pipeline studies using the public roadway for their facilities have trouble encouraging public participation. Problems resulting from a lack of public involvement are documented. A public participation process designed to gather meaningful public input is presented through a case study of a public roadway pipeline study in southern Ontario. Techniques are outlined to effectively stimulate public interest and document the public involvement process. Recommendations are made as to the transferability of this process to other jurisdictions.

    Vehicular emitted air pollutant concentrations were studied near three types of roadways in Austin, Texas: (1) State Highway 71 (SH-71), a heavily traveled arterial highway dominated by passenger vehicles; (2) Interstate 35 (I-35), a limited access highway north of Austin in Georgetown; and (3) Farm to Market Road 973 (FM-973), a heavily traveled surface roadway dominated by truck traffic. Air pollutants examined include carbon monoxide (CO), oxides of nitrogen (NO x), and carbonyl species in the gas-phase. In the particle phase, ultrafine particle (UFP) concentrations (diameter road were found to be the most important factors determining UFP concentrations near the roadways. Since wind directions were not consistent during the sampling periods, distances along wind trajectories from the roadway to the sampling points were used to study the decay characteristics of UFPs. Under perpendicular wind conditions, for all studied roadway types, particle number concentrations increased dramatically moving from the upwind side to the downwind side. The elevated particle number concentrations decay exponentially with increasing distances from the roadway with sharp concentration gradients observed within 100-150 m, similar to previously reported studies. A single exponential decay curve was found to fit the data collected from all three roadways very well under perpendicular wind conditions. No consistent pattern was observed for UFPs under parallel wind conditions. However, regardless of wind conditions, particle concentrations returned to background levels within a few hundred meters of the roadway. Within measured UFP size ranges, smaller particles (6-25 nm) decayed faster than larger ones (100-300 nm). Similar decay rates were observed among UFP number, surface, and volume.

    2018-02-01

    Zonal disintegration phenomenon was found in deep mining roadway surrounding rock. It seriously affects the safety of mining and underground engineering and it may lead to the occurrence of natural disasters. in deep mining roadway surrounding rock, tectonic stress in deep mining roadway rock mass, horizontal stress is much greater than the vertical stress, When the direction of maximum principal stress is parallel to the axis of the roadway in deep mining, this is the main reasons for Zonal disintegration phenomenon. Using ABAQUS software to numerical simulation of the three-dimensional model of roadway rupture formation process systematically, and the study shows that when The Direction of maximum main stress in deep underground mining is along the roadway axial direction, Zonal disintegration phenomenon in deep underground mining is successfully reproduced by our numerical simulation..numerical simulation shows that using ABAQUA simulation can reproduce Zonal disintegration phenomenon and the formation process of damage of surrounding rock can be reproduced. which have important engineering practical significance.

  9. Deformation and Failure Mechanism of Roadway Sensitive to Stress Disturbance and Its Zonal Support Technology

    Directory of Open Access Journals (Sweden)

    Qiangling Yao

    2016-01-01

    Full Text Available The 6163 haulage roadway in the Qidong coal mine passes through a fault zone, which causes severe deformation in the surrounding rock, requiring repeated roadway repairs. Based on geological features in the fault area, we analyze the factors affecting roadway deformation and failure and propose the concept of roadway sensitive to stress disturbance (RSSD. We investigate the deformation and failure mechanism of the surrounding rocks of RSSD using field monitoring, theoretical analysis, and numerical simulation. The deformation of the surrounding rocks involves dilatation of shallow rocks and separation of deep rocks. Horizontal and longitudinal fissures evolve to bed separation and fracture zones; alternatively, fissures can evolve into fracture zones with new fissures extending to deeper rock. The fault affects the stress field of the surrounding rock to ~27 m radius. Its maximum impact is on the vertical stress of the rib rock mass and its minimum impact is on the vertical stress of the floor rock mass. Based on our results, we propose a zonal support system for a roadway passing through a fault. Engineering practice shows that the deformation of the surrounding rocks of the roadway can be effectively controlled to ensure normal and safe production in the mine.

  10. Deformation mechanisms in a coal mine roadway in extremely swelling soft rock.

    Li, Qinghai; Shi, Weiping; Yang, Renshu

    2016-01-01

    The problem of roadway support in swelling soft rock was one of the challenging problems during mining. For most geological conditions, combinations of two or more supporting approaches could meet the requirements of most roadways; however, in extremely swelling soft rock, combined approaches even could not control large deformations. The purpose of this work was to probe the roadway deformation mechanisms in extremely swelling soft rock. Based on the main return air-way in a coal mine, deformation monitoring and geomechanical analysis were conducted, as well as plastic zone mechanical model was analysed. Results indicated that this soft rock was potentially very swelling. When the ground stress acted alone, the support strength needed in situ was not too large and combined supporting approaches could meet this requirement; however, when this potential released, the roadway would undergo permanent deformation. When the loose zone reached 3 m within surrounding rock, remote stress p ∞ and supporting stress P presented a linear relationship. Namely, the greater the swelling stress, the more difficult it would be in roadway supporting. So in this extremely swelling soft rock, a better way to control roadway deformation was to control the releasing of surrounding rock's swelling potential.

    2009-01-01

    At present, the most surrounding rocks of sandstone-type uranium mines in China are mudstone, sandstone, pelitic siltstone, and so on. They show the characteristics of soft rock. Such uranium deposit is not fit for in-situ leaching. If the uranium ores are mined by conventional mining method, one of the problems to be solved is the support technique in the soft rock roadway. So, taking a uranium mine in Inner Mongolia as the research object, the support technique in the soft rock roadway of the sandstone-type uranium deposits is studied. Through on-site engineering geological investigation and laboratory test, the main reasons for roadway damage are analyzed. A technique of support in the soft rock roadway of sandstone-type uranium deposits is put forward by drawing on the expericnce of soft rock roadway support in coal mines. The roadway shape and support parameters are optimized by using a numerical simulation method. The results verified the feasibility of the supporting technique. (authors)

    All medical schools in the UK are required to be able to provide evidence of competence in clinical communication in their graduates. This is usually provided by summative assessment of clinical communication, but there is considerable variation in how this is carried out. This study aimed to gain insight into the current assessment of clinical communication in UK medical schools. The survey was sent via e-mail to communication leads who then were asked to consult with all staff within their medical school involved in the assessment of communication. Results were obtained from 27 out of 33 schools (response rate 82%) and a total of 34 courses. The average number of assessments per year was 2.4 (minimum 0, maximum 10). The Objective Structured Clinical Exam (OSCE) was the most commonly used method of assessment (53%). Other assessments included MCQ and workplace based assessments. Only nine courses used a single method of assessment. Issues raised included, logistics and costs of assessing mainly by OSCE, the robustness and reliability of such exams and integration with other clinical skills. It is encouraging that a variety of assessment methods are being used within UK medical schools and that these methods target different components of clinical communication skills acquisition.

    To describe the concerns, confidence, and barriers of practicing hospitalists around serious illness communication. Hospitalist physicians are optimally positioned to provide primary palliative care, yet their experiences in serious illness communication are not well described. Web-based survey, conducted in May 2016. The survey link was distributed via email to 4000 members of the Society of Hospital Medicine. The 39-item survey assessed frequency of concerns about serious illness communication, confidence for common tasks, and barriers using Likert-type scales. It was developed by the authors based on prior work, a focus group, and feedback from pilot respondents. We received 332 completed surveys. On most or every shift, many participants reported having concerns about a patient's or family's understanding of prognosis (53%) or the patient's code status (63%). Most participants were either confident or very confident in discussing goals of care (93%) and prognosis (87%). Fewer were confident or very confident in responding to patients or families who had not accepted the seriousness of an illness (59%) or in managing conflict (50%). Other frequently cited barriers were lack of time, lack of prior discussions in the outpatient setting, unrealistic prognostic expectations from other physicians, limited institutional support, and difficulty finding records of previous discussions. Our results suggest opportunities to improve hospitalists' ability to lead serious illness communication by increasing the time hospitalists have for discussions, improving documentation systems and communication between inpatient and outpatient clinicians, and targeted training on challenging communication scenarios.

    Fuhr, Peter L.; Ambrose, Timothy P.; Huston, Dryver R.; McPadden, Adam P.

    1995-04-01

    In this paper we report the development of a fiber optic corrosion sensing system that complements and/or surpasses the capabilities of conventional corrosion sensing techniques. The sensing system is based on evanescent wave phenomena and in the configured sensor allows for the detection of general corrosion on and within materials. Based on the authors' experience installing may kilometers of fiberoptic sensors into large civil structures such as multistory buildings, hydroelectric dams, and railway/roadway bridges, we are (currently) embedding these sensors into bridge test members -- limited structures that are being subjected to accelerated corrosion testing conditions. Three Vermont Agency of Transportation bridges, one in a low salt use region, one in a medium salt use region, and the third in a high salt use region, are being selected and will be instrumented with these embedded fiber optic corrosion sensors. Monitoring of chloride penetration and rebar corrosion status will be measured during the course of a longitudinal study. The specific sensing mechanism and design for robustness (to allow survival of the embedding process during repaving of the bridges) are discussed and laboratory and initial field results are presented.

The physical components of Federal telecommunications systems and networks include telephone and digital data switching facilities and primary common user communications centers; Special purpose local delivery message switching and exchange facilities; Government owned or leased radio systems; Technical control facilities which are under exclusive control of a government agency. This thesis describes the logical design of a proposed decision support system for use by the National Communications System in forecasting technology, prices, and costs. It is general in nature and only includes those forecasting models which are suitable for computer implementation. Because it is a logical design it can be coded and applied in many different hardware and/or software configurations.

    Chitnis, E. V.

    The paper describes the role of space communication in promoting national development with special reference to experiments conducted in India, namely SITE (1975-1976), STEP (1977-1979) and APPLE (1981 onwards). The impact of these experiments in economic, cultural and educational terms are discussed, pointing out social implications involved in using advance space communication technology for instruction and information in the areas of education, national integration and development. The paper covers special requirements which arise when a communication system covers backward and remote rural areas in a developing country. The impact on the population measured by conducting social surveys has been discussed - especially the gains of predominently illiterate new media - participants have been highlighted. Possibilities of improving skills of teachers, the quality of the primary and higher education have been covered. The preparation required both on ground as well as space to derive benefits of space technology are considered. A profile of INSAT which marks the culmination of the experimental phase and the beginning of operational domestic satellite system is sketched.

    The trapezoidal cross-section roadway, driven along with its medium and fine grain sandstone roof in special thick stratum, was situated in shale strata of the Wu{sub 2} coal seam of the Shihhotze Perno-carboniferous group. Rock-lining wall was employed in roadway, which its roof is in the free situation. Under the action of virgin stress, the surrounding rock of roadway was stable. While under the action of fixed abutment pressure arisen from protection pillar of roadway, which if two sides seams were extracted the free strong roof of roadway was stable. But its two sides rock-lining walls was fractured, partially broken into pieces, and its floor heave was obvious. The velocity of floor heave is 0.4 - 0.8 mm/d. The size of the broken zone of surrounding rock of roadway doubled. An effective load coefficient of surrounding rock was quoted to illustrate these phenomena. The main reasons of roadway convergence are that rock property of surrounding rock is inferior, protection pillars affects its stability, and the supporting pattern employed is improper. Effective measures to control roadway convergence should be bolting and grouting lining, which mainly consolidate surrounding rock of roadway. 4 refs., 1 fig.

    The purpose of the research study was to determine whether ADHD- and texting-related driving impairments are mediated by extended visual glances away from the roadway. Sixty-one adolescents (ADHD =28, non-ADHD =33; 62% male; 11% minority) aged 16-17 with a valid driver's license were videotaped while engaging in a driving simulation that included a No Distraction, Hands-Free Phone Conversation, and Texting condition. Two indicators of visual inattention were coded: 1) percentage of time with eyes diverted from the roadway; and 2) number of extended (greater than 2 s) visual glances away from the roadway. Adolescents with ADHD displayed significantly more visual inattention to the roadway on both visual inattention measures. Increased lane position variability among adolescents with ADHD compared to those without ADHD during the Hands-Free Phone Conversation and Texting conditions was mediated by an increased number of extended glances away from the roadway. Similarly, texting resulted in decreased visual attention to the roadway. Finally, increased lane position variability during texting was also mediated by the number of extended glances away from the roadway. Both ADHD and texting impair visual attention to the roadway and the consequence of this visual inattention is increased lane position variability. Visual inattention is implicated as a possible mechanism for ADHD- and texting-related deficits and suggests that driving interventions designed to address ADHD- or texting-related deficits in adolescents need to focus on decreasing extended glances away from the roadway.

    2016-01-01

    Full Text Available A self-designed experimental installation for transient heat transfer in the modelling surrounding rock mass of high geothermal roadways was elaborated in this paper. By utilizing the new installation, the temperature variation rules in surrounding rock mass of the high geothermal roadway during mechanical ventilation were studied. The results show that the roadway wall temperature decreases dramatically at the early stage of ventilation, and the temperature at every position of the surrounding rock mass is decreasing constantly with time passing by. From roadway wall to deep area, the temperature gradually increases until reaching original rock temperature. The relationship between dimensionless temperature and dimensionless radius demonstrates approximately exponential function. Meanwhile, the temperature disturbance range in the simulated surrounding rock mass extends gradually from the roadway wall to deep area in the surrounding rock mass. Besides, as the air velocity increases, heat loss in the surrounding rock mass rises and the ratio of temperature reduction becomes larger, the speed of disturbance range expansion also gets faster.

  6. Support technology of deep roadway under high stress and its application

    2016-01-01

    Roadway instability has been a major concern in the fields of mining engineering. This paper aims to pro-vide practical and efficient strategy to support the roadways under high in-situ stress. A case study on the stability of deep roadways was carried out in an underground mine in Gansu province, China. Currently, the surrounding rock strata is extremely fractured, which results in a series of engineering disasters, such as side wall collapse and severe floor heave in the past decades. Aiming to solve these problems, an improved support method was proposed, which includes optimal bolt parameters and arrangement, floor beam layout by grooving, and full length grouting. Based on the modeling results by FLAC3D, the new support method is much better than the current one in terms of preventing the large deformation of sur-rounding rock and restricting the development of plastic zones. For implementation and verification, field experiments, along with deformation monitoring, were conducted in the 958 level roadway of Mining II areas. The results show that the improved support can significantly reduce surrounding rock deforma-tion, avoid frequent repair, and maintain the long-term stability of the roadway. Compared to the original support, the new support method can greatly save investment of mines, and has good application value and popularization value.

    Peknik, J

    1983-05-01

    The use of concrete blocks for strata control in mine roadways driven in thin coal seams is evaluated. Two types of prefabricated blocks are used: BZT blocks made of reinforced concrete and yielding elements or popilbet blocks made of a mixture of fly ash (from coal power plants) and concrete. When the popilbet blocks were used no yielding elements were necessary. Mechanical properties of blocks made of reinforced concrete were controlled by yielding elements. Mechanical properties (compression strength) of the popilbet blocks were controlled by proportion of water, cement and fly ash. The BZT and the popilbet blocks were used for strata control in mine roadways in coal seams from 60 to 80 cm thick and dip angle from 5 to 18 degrees. Use of the BZT and the popilbet blocks reduced roadway deformation by about 50% in comparison to traditional strata control methods (timber cribbings, use of waste rock, etc.). Use of the blocks is explained. The BZT and the popilbet blocks were placed in a roadway wall. Height of the block wall equaled coal seam thickness. Yielding arched steel supports and timber liners were used for strata control in the roadway. The popilbet blocks were 50% less expensive than the BZT blocks. 9 references

    Full Text Available The environmental determinants of pediatric embryonal tumors remain unclear. Because of the growing concern over the impact of exposures to traffic-related air pollution on pediatric cancer, we conducted a population-based study evaluating the impact of maternal residential proximity to major roadways on the risk of pediatric embryonal tumors in offspring. We identified children diagnosed with neuroblastoma, Wilms tumor, retinoblastoma, or hepatoblastoma at <5 years of age from the Texas Cancer Registry and selected unaffected controls from birth certificates. Two residential proximity measures were used: (1 distance to the nearest major roadway, and (2 within 500 m of a major roadway. Logistic regression was used to estimate the adjusted odds ratio (aOR and 95% confidence interval (CI for each proximity measure on pediatric embryonal tumors. The odds of an embryonal tumor were increased in children born to mothers living within 500 m of a major roadway (aOR = 1.24, 95% CI: 1.00, 1.54. This was consistent for most tumor subtypes, with the strongest associations observed for unilateral retinoblastoma (aOR = 2.57, 95% CI: 1.28, 5.15, for every kilometer closer the mother lived to the nearest major roadway. These findings contribute to the growing evidence that traffic-related air pollution may increase risk for certain pediatric tumors.

    Patient-physician communication often occurs outside the clinic setting; many institutions discourage electronic communication outside of established electronic health record systems. Little empirical data are available on patient interest in electronic communication and Web-based health tools that are technically feasible but not widely available. To explore patient behavior and interest in using the Internet to contact physicians. National cross-sectional online survey. A sample of 4,510 CVS customers with at least one chronic condition in the household was used to target patients with chronic conditions and their caregivers. Subjects were identified from a national panel of over 100,000 retail pharmacy customers. Of those sampled, 2,252 responded (50.0 % response rate). Survey measures included demographic and health information, patient use of email and Facebook to contact physicians, and patient interest in and use of Web-based tools for health. A total of 37 % of patients reported contacting their physicians via email within the last six months, and 18 % via Facebook. Older age was negatively associated with contacting physicians using email (OR 0.57 [95 % CI 0.41-0.78]) or Facebook (OR 0.28 [0.17-0.45]). Non-white race (OR 1.61 [1.18-2.18] and OR 1.82 [1.24-2.67]) and caregiver status (OR 1.58 [1.27-1.96] and OR 1.71 [1.31- 2.23]) were positively associated with using email and Facebook, respectively. Patients were interested in using Web-based tools to fill prescriptions, track their own health, and access health information (37-57 %), but few were currently doing so (4-8 %). In this population of retail pharmacy users, there is strong interest among patients in the use of email and Facebook to communicate with their physicians. The findings highlight the gap between patient interest for online communication and what physicians may currently provide. Improving and accelerating the adoption of secure Web messaging systems is a possible solution that

    Full Text Available Research indicates that higher levels of traffic-related pollution exposure increase the risk of diabetes, but the association between road proximity and diabetes risk remains unclear. To assess and quantify the association between residential proximity to major roadways and type 2 diabetes, a systematic review and meta-analysis was performed. Embase, Medline, and Web of Science were searched for eligible studies. Using a random-effects meta-analysis, the summary relative risks (RRs were calculated. Bayesian meta-analysis was also performed. Eight studies (6 cohort and 2 cross-sectional with 158,576 participants were finally included. The summary unadjusted RR for type 2 diabetes associated with residential proximity to major roadways was 1.24 (95% confidence interval [CI]: 1.07–1.44, p = 0.001, I2 = 48.1%. The summary adjusted RR of type 2 diabetes associated with residential proximity to major roadways was 1.12 (95% CI: 1.03–1.22, p = 0.01, I2 = 17.9%. After excluding two cross-sectional studies, the summary results suggested that residential proximity to major roadways could increase type 2 diabetes risk (Adjusted RR = 1.13; 95% CI: 1.02–1.27, p = 0.025, I2 = 36.6%. Bayesian meta-analysis showed that the unadjusted RR and adjusted RR of type 2 diabetes associated with residential proximity to major roadways were 1.22 (95% credibility interval: 1.06–1.55 and 1.13 (95% credibility interval: 1.01–1.31, respectively. The meta-analysis suggested that residential proximity to major roadways could significantly increase risk of type 2 diabetes, and it is an independent risk factor of type 2 diabetes. More well-designed studies are needed to further strengthen the evidence.

    The effects of chronic exposure to increasing levels of human-induced underwater noise on marine animal populations reliant on sound for communication are poorly understood. We sought to further develop methods of quantifying the effects of communication masking associated with human-induced sound on contact-calling North Atlantic right whales (Eubalaena glacialis) in an ecologically relevant area (~10,000 km(2) ) and time period (peak feeding time). We used an array of temporary, bottom-mounted, autonomous acoustic recorders in the Stellwagen Bank National Marine Sanctuary to monitor ambient noise levels, measure levels of sound associated with vessels, and detect and locate calling whales. We related wind speed, as recorded by regional oceanographic buoys, to ambient noise levels. We used vessel-tracking data from the Automatic Identification System to quantify acoustic signatures of large commercial vessels. On the basis of these integrated sound fields, median signal excess (the difference between the signal-to-noise ratio and the assumed recognition differential) for contact-calling right whales was negative (-1 dB) under current ambient noise levels and was further reduced (-2 dB) by the addition of noise from ships. Compared with potential communication space available under historically lower noise conditions, calling right whales may have lost, on average, 63-67% of their communication space. One or more of the 89 calling whales in the study area was exposed to noise levels ≥120 dB re 1 μPa by ships for 20% of the month, and a maximum of 11 whales were exposed to noise at or above this level during a single 10-min period. These results highlight the limitations of exposure-threshold (i.e., dose-response) metrics for assessing chronic anthropogenic noise effects on communication opportunities. Our methods can be used to integrate chronic and wide-ranging noise effects in emerging ocean-planning forums that seek to improve management of cumulative effects

  7. Using Theory to Design Evaluations of Communication Campaigns: The Case of the National Youth Anti-Drug Media Campaign.

    Hornik, Robert C; Yanovitzky, Itzhak

    2003-05-01

    We present a general theory about how campaigns can have effects and suggest that the evaluation of communication campaigns must be driven by a theory of effects. The National Youth Anti-Drug Media Campaign illustrates both the theory of campaign effects and implications that theory has for the evaluation design. Often models of effect assume that individual exposure affects cognitions that continue to affect behavior over a short term. Contrarily, effects may operate through social or institutional paths as well as through individual learning, require substantial levels of exposure achieved through multiple channels over time, take time to accumulate detectable change, and affect some members of the audience but not others. Responsive evaluations will choose appropriate units of analysis and comparison groups, data collection schedules sensitive to lagged effects, samples able to detect subgroup effects, and analytic strategies consistent with the theory of effects that guides the campaign.

    In this work, we describe the digital imaging network (DIN), picture archival and communication system (PACS), and radiology information system (RIS) currently being implemented at the Clinical Center, National Institutes of Health (NIH). These systems are presently in clinical operation. The DIN is a redundant meshed network designed to address gigabit density and expected high bandwidth requirements for image transfer and server aggregation. The PACS projected workload is 5.0 TB of new imaging data per year. Its architecture consists of a central, high-throughput Digital Imaging and Communications in Medicine (DICOM) data repository and distributed redundant array of inexpensive disks (RAID) servers employing fiber-channel technology for immediate delivery of imaging data. On demand distribution of images and reports to clinicians and researchers is accomplished via a clustered web server. The RIS follows a client-server model and provides tools to order exams, schedule resources, retrieve and review results, and generate management reports. The RIS-hospital information system (HIS) interfaces include admissions, discharges, and transfers (ATDs)/demographics, orders, appointment notifications, doctors update, and results.

  9. The role of National Strategies in maintaining Competitive Edge in Information and Communication Technologies

    Directory of Open Access Journals (Sweden)

    Full Text Available This paper examines the economical impact of IPv6, Internet Protocol's next generation. Technically, IPv6 represents an upgrade, an evolution that offers the resources necessary for deeper and wider market penetration of the IP technology, to support the needs of a global economy, to build new products and new services. Politically and economically it has the potential of being a quiet revolution. Countries that trailed US into the information revolution recognize this opportunity to take a leading role in its next expansion phase and have developed national strategies to help better position their respective economies. Despite understanding the constraints imposed by the current version of IP, the private sector is currently inclined to largely ignore IPv6 because of its initial deployment costs and long term returns. Forced by high investor expectations to focus exclusively on the immediate bottom line it trades long term growth opportunities for short term benefits revolving around productivity increases. The paper analyses the importance of a National Strategy in driving IPv6 adoption and in closing a widening knowledge and deployment gap between US and countries such as China, Japan, Korea and the EU.

  10. Effect of Weight and Roadway Grade on the Fuel Economy of Class-8 Frieght Trucks

    Franzese, Oscar [ORNL; Davidson, Diane [ORNL

    2011-11-01

    In 2006-08, the Oak Ridge National Laboratory, in collaboration with several industry partners, collected real-world performance and situational data for long-haul operations of Class-8 trucks from a fleet engaged in normal freight operations. Such data and information are useful to support Class-8 modeling of combination truck performance, technology evaluation efforts for energy efficiency, and to provide a means of accounting for real-world driving performance within combination truck research and analyses. The present study used the real-world information collected in that project to analyze the effects that vehicle speed and vehicle weight have on the fuel efficiency of Class-8 trucks. The analysis focused on two type of terrains, flat (roadway grades ranging from -1% to 1%) and mild uphill terrains (roadway grades ranging from 1% to 3%), which together covered more than 70% of the miles logged in the 2006-08 project (note: almost 2/3 of the distance traveled on mild uphill terrains was on terrains with 1% to 2% grades). In the flat-terrain case, the results of the study showed that for light and medium loads, fuel efficiency decreases considerably as speed increases. For medium-heavy and heavy loads (total vehicle weight larger than 65,000 lb), fuel efficiency tends to increase as the vehicle speed increases from 55 mph up to about 58-60 mph. For speeds higher than 60 mph, fuel efficiency decreases at an almost constant rate with increasing speed. At any given speed, fuel efficiency decreases and vehicle weight increases, although the relationship between fuel efficiency and vehicle weight is not linear, especially for vehicle weights above 65,000 lb. The analysis of the information collected while the vehicles were traveling on mild upslope terrains showed that the fuel efficiency of Class-8 trucks decreases abruptly with vehicle weight ranging from light loads up to medium-heavy loads. After that, increases in the vehicle weight only decrease fuel

    2015-04-01

    The purpose of this study was to investigate motorcycle-to-barrier crash frequency on horizontally curved roadway sections in Washington State using police-reported crash data linked with roadway data and augmented with barrier presence information. Data included 4915 horizontal curved roadway sections with 252 of these sections experiencing 329 motorcycle-to-barrier crashes between 2002 and 2011. Negative binomial regression was used to predict motorcycle-to-barrier crash frequency using horizontal curvature and other roadway characteristics. Based on the model results, the strongest predictor of crash frequency was found to be curve radius. This supports a motorcycle-to-barrier crash countermeasure placement criterion based, at the very least, on horizontal curve radius. With respect to the existing horizontal curve criterion of 820 feet or less, curves meeting this criterion were found to increase motorcycle-to-barrier crash frequency rate by a factor of 10 compared to curves not meeting this criterion. Other statistically significant predictors were curve length, traffic volume and the location of adjacent curves. Assuming curves of identical radius, the model results suggest that longer curves, those with higher traffic volume, and those that have no adjacent curved sections within 300 feet of either curve end would likely be better candidates for a motorcycle-to-barrier crash countermeasure.

    By investigating surface runoff from urban roadway in Chongqing, we assessed the characteristics of surface runoff pollution and the effect of rainfall intensity and antecedent dry weather period on water quality. Using multivariate statistical analysis of data of runoff quality, potential pollutants discharged from urban roadway runoff were identified. The results show that the roadway runoff has high levels of COD, TP and TN, the EMC were 60.83-208.03 mg x L(-1), 0.47-1.01 mg x L(-1) and 2.07-5.00 mg x L(-1) respectively, being the main pollutants; The peaks of pollutant concentration are ahead of or synchronous with the peak of runoff volume; the peaks of pollutant concentrations are mostly occurred within 10 minutes of rainfall. The heavy metal concentrations fluctuate dentately during runoff proceeding. Two potential pollution sources to urban roadway runoff apportioned by using principal component analysis are: vehicle's traffic loss and atmospheric dry and wet deposition, and municipal wastes.

    This article in view of the complex roof conditions was carried on study about the new technology of removing gangue and retaining roadway, and tells a method of progressive reinforced concrete wall segment with gangue to keep the roadway, the roadway beside the support system is mainly composed of the lining, waste rock wall and the outer wall, the wall and the outer wall of concrete material width to build the strength of the progressive type filling body, waste rock wall with woven bag with waste rock assembled, paragraphs geological survey on the actual distance should be based on working face. This method relies on the interior of the gangue wall to make the pressure control and allow the roof to sink. In this paper, the finite deformation control of the roof is realized by the gangue wall and the high strength filling body. This method has the characteristics of low entry cost, good forming of roadway, high security and good stability, and can be applied to complex geological conditions such as hard roof.

  15. Distribution of Side Abutment Stress in Roadway Subjected to Dynamic Pressure and Its Engineering Application

    2015-01-01

    Full Text Available The borehole stress-meter was employed in this study to investigate the distribution of the side abutment stress in roadway subjected to dynamic pressure. The results demonstrate that the side abutment stress of the mining roadway reaches a peak value when the distance to the gob is 8 m and the distribution curve of the side abutment stress can be divided into three zones: stress rising zone, stress stabilizing zone, and stress decreasing zone. Further numerical investigation was carried out to study the effect of the coal mass strength, coal seam depth, immediate roof strength, and thickness on the distribution of the side abutment stress. Based on the research results, we determined the reasonable position of the mining roadway and the optimal width of the barrier pillar. The engineering application demonstrates that the retention of the barrier pillar with a width of 5 m along the gob as the haulage roadway for the next panel is feasible, which delivers favorable technological and economic benefits.

  4. The effects of roadway characteristics on farm equipment crashes: A GIS approach

    Science.gov (United States)

    Greenan, Mitchell Joseph

    Tractors and other self-propelled farm equipment, such as combines, sprayers, and towed grain carts, are often used on public roadways as the primary means for traveling from homestead to homestead or from homestead to a distributer. Increased roadway exposure has led to a growing concern for crashes involving farm equipment on the public roadway. A handful of studies exist examining public roadway crashes involving farm equipment using crash data, but none thus far have evaluated road segment data to identify road-specific risk factors. The objective of this study is to identify if roadway characteristics (traffic density, speed limit, road type, surface type, road width, and shoulder width) affect the risk of a crash involving farm equipment on Iowa public roadways. A retrospective cohort study of Iowa roads was conducted to identify the types of roads that are at an increased risk of having a farm-equipment crash on them. Crash data from the Iowa Department of Transportation (to identify crashes) were spatial linked to Iowa roadway data using Geographic Information Systems (GIS). Logistic regression was used to calculate ORs and 95% CL. Out of 319,705 road segments in Iowa, 0.4% segments (n=1,337) had a farm equipment crash from 2005-2011. The odds of having a farm equipment crash were significantly higher for road segments with increased traffic density and speed limit. Roads with an average daily traffic volume of at least 1,251 vehicles were at a 5.53 times greater odds of having a crash than roads with a daily traffic volume between 0-30 vehicles. (CI: 3.90-7.83). Roads with a posted speed limit between 50mph and 60mph were at a 4.88 times greater odds of having a crash than roads with a posted speed limit of 30mph or less. (CI: 3.85-6.20). Specific roadway characteristics such as roadway and shoulder width were also associated with the risk of a crash. For every 5 foot increase in road width, the odds for a crash decreased by 6 percent (CI: 0.89-0.99) and

    1999-07-01

    Full Text Available Urine analysis, serumbiochemical profile and a cortical wedge biopsy for histopathological examination was performed on 42 South African National Defence Force (SANDF dogs from around the country. The only significant finding on urine analysis and serum biochemistry was a relatively large number (16/42 of dogs with elevated serum inorganic phosphate levels. Histopathology revealed that only 9 of the animals had normal kidneys reflected in the wedge biopsy material, with over 50%of them showing signs of glomerular pathology (primarily mesangioproliferative glomerulonephritis. Other conditions detected histopathologically were haemosiderosis (47 % of animals, focal nephrosis (2.4 %, membranoproliferative glomerulonephritis (2.4 %, focal interstitial nephritis (4.7 % and acute tubular nephrosis (4.7 %. The lesions observed were of limited distribution and extent; this histopathological finding may account for the absence of significant abnormalities on urine analysis or serum biochemistry profiles. It appears from these results that a large percentage of the SANDF population would be expected to have mild renal lesions, but that these lesions are not severe enough to lead to clinical signs. The findings of this study are similar to those of randomly selected populations of non-military dogs performed in other areas of the world, which also demonstrated an unexpectedly high incidence of histopathological renal pathology in dogs considered healthy. These lesions may well, however, play a role in later life, and it is recommended that military veterinarians maintain an index of suspicion for renal disease, particularly glomerular disease. The aetiology of the histopathological lesions is unknown.

  6. "Love me, parents!": impact evaluation of a national social and behavioral change communication campaign on maternal health outcomes in Tanzania.

    Despite marked improvements over the last few decades, maternal mortality in Tanzania remains among the world's highest at 454 maternal deaths per 100,000 live births. Many factors contribute to this disparity, such as a lack of attendance at antenatal care (ANC) services and low rates of delivery at a health facility with a skilled provider. The Wazazi Nipendeni (Love me, parents) social and behavioral change communication campaign was launched in Tanzania in 2012 to improve a range of maternal health outcomes, including individual birth planning, timely ANC attendance, and giving birth in a healthcare facility. An evaluation to determine the impact of the national Wazazi Nipendeni campaign was conducted in five purposively selected regions of Tanzania using exit interviews with pregnant and post-natal women attending ANC clinics. A total of 1708 women were interviewed regarding campaign exposure, ANC attendance, and individual birth planning. Over one third of interviewed women (35.1%) reported exposure to the campaign in the last month. The more sources from which women reported hearing the Wazazi Nipendeni message, the more they planned for the birth of their child (β = 0.08, p = .001). Greater numbers of types of exposure to the Wazazi Nipendeni message was associated with an increase in ANC visits (β = 0.05, p = .004). Intervention exposure did not significantly predict the timing of the first ANC visit or HIV testing in the adjusted model, however, findings showed that exposure did predict whether women delivered at a health care facility (or not) and whether they tested for HIV with a partner in the unadjusted models. The Wazazi Nipendeni campaign shows promise that such a behavior change communication intervention could lead to better pregnancy and childbirth outcomes for women in low resource settings. For outcomes such as HIV testing, message exposure showed some promising effects, but demographic variables such as age and socioeconomic status

    2018-01-01

    This review manuscript examines the burden and national response to non-communicable diseases (NCDs), food and nutrition security in Vietnam from 1975 to 2015. We extracted data from peer-reviewed manuscripts and reports of nationally representative surveys and related policies in Vietnam. In 2010, NCDs accounted for 318,000 deaths (72% of total deaths), 6.7 million years of life lost, and 14 million disability-adjusted life years in Vietnam. Cardiovascular diseases, cancers, chronic obstructive pulmonary disease, and diabetes mellitus were major contributors to the NCD burden. Adults had an increased prevalence of overweight and obesity (2.3% in 1993 to 15% in 2015) and hypertension (15% in 2002 to 20% in 2015). Among 25-64 years old in 2015, the prevalence of diabetes mellitus was 4.1% and the elevated blood cholesterol was 32%. Vietnamese had a low physical activity level, a high consumption of salt, instant noodles and sweetened non-alcoholic beverages as well as low consumption of fruit and vegetables and seafood. The alcohol consumption and smoking prevalence were high in men. Exposure to second-hand tobacco smoke was high in men, women and youths at home, work, and public places. In Vietnam, policies for NCD prevention and control need to be combined with strengthened law enforcement and increased program coverage. There were increased food production and improved dietary intake (e.g., energy intake and protein-rich foods thanked to appropriate economic, agriculture, and nutrition strategies. NCDs and their risk factors are emerging problems in Vietnam, which need both disease-specific and sensitive strategies in health and related sectors.

  11. Efficacy of a national hydrological risk communication strategy: Domestic wastewater treatment systems in the Republic of Ireland

    2018-03-01

    A significant body of research has focused on the role of domestic wastewater treatment systems (DWWTSs) as sources of human-specific aquatic contaminants in both developed and developing regions. However, to date few studies have sought to investigate the awareness, attitudes and behaviours of DWWTS owners and the efficacy of associated communication initiatives. The current study provides an examination of a public national engagement campaign undertaken in the Republic of Ireland which seeks to minimise the impact of DWWTSs on human and ecological health via concurrent inspection and information dissemination. Overall, 1634 respondents were surveyed using a "before and after" study design to capture if and how awareness, attitudes and behaviours evolved over time. Findings suggest that whilst the campaign provided a modest baseline to raise general awareness associated with the basic operational and maintenance requirements of DWWTS, there has been little or no behavioural engagement as a result, suggesting a significant awareness-behaviour gap. Accordingly, efforts to minimise potential human and ecological impacts have been unsuccessful. Moreover, results suggest that public attitudes towards water-related regulation and policy became increasingly negative over the study period due to parallel political and economic issues, further complicating future engagement. Future strategies, both in Ireland and further afield, should focus on health-based demographically-focused message framing to achieve significant knowledge and attitudinal shifts amongst specific population cohorts, and thus bring about significant behavioural change. Study findings and recommendations may be used by myriad stakeholders including local, provincial and national authorities to effectively engage with individuals and communities prior to and during implementation of legislative and policy-based instruments within numerous spheres including climate change adaptation, environmental

    Recent efforts in the science education community have highlighted the need to integrate research and theory from science communication research into more general science education scholarship. These synthesized research perspectives are relatively novel but serve an important need to better understand the impacts that the advent of rapidly emerging technologies will have on a new generation of scientists and engineers including their formal communication with engaged citizenry. This cross-national study examined postsecondary science and engineering students' ( n = 254 from five countries: Austria, Finland, France, Israel, and USA) perspectives on the role of science communication in their own formal science and engineering education. More broadly, we examined participants' understanding of their perceived responsibilities of communicating science and engineering to the general public when an issue contains complex social and ethical implications (SEI). The study is contextualized in the emergent technology of nanotechnology for which SEI are of particular concern and for which the general public often perceives conflicting risks and benefits. Findings indicate that student participants' hold similar views on the need for their own training in communication as future scientists and engineers. When asked about the role that ethics and risk perception plays in research, development, and public communication of nanotechnology, participants demonstrate similar trajectories of perspectives that are, however, often anchored in very different levels of beginning concern. Results are discussed in the context of considerations for science communication training within formal science education curricula globally.

    When engineering students graduate and enter the world of work, they make the transition from an academic to a professional community of knowledge. The importance of oral and written communication to the professional success and advancement of engineers is well documented. For example, studies such as those conducted by Mailloux (1989) indicate that communicating data, information, and knowledge takes up as much as 80% of an engineer's time. However, these same studies also indicate that many engineering graduates cannot (a) write technical reports that effectively inform and influence decisionmaking, (b) present their ideas persuasively, and (c) communicate with their peers. If these statements are true, how is learning to communicate effectively in their professional knowledge community different for engineering students educated in the United States but who come from other cultures-cultures in which English is not the primary language of communication? Answering this question requires adequate and generalizable data about these students' communications abilities, skills, and competencies. To contribute to the answer, we undertook a national (mail) survey of 1,727 student members of the American Institute of Aeronautics and Astronautics (AIAA). The focus of our analysis and this paper is a comparison of the responses of 297 student members for whom English is a second language with the responses of 1,430 native English speaking students to queries regarding career choice, bilingualism and language fluency, communication skills, collaborative writing, computer use, and the use of electronic (computer) networks.

    In the context of crisis and disasters, school-aged children are a vulnerable group with fewer coping resources than adults. The school is a key arena for preventive interventions; teachers can be given a key role in large-scale school-based interventions following a man-made or natural disaster. This paper describes a practical example of designing a school-based population-level intervention. The preventive measures were delivered as a national communication strategy between teachers and pupils aged 6-19 concerning the terror attack on 22 July 2011 in Norway. The strategy is based on principles from international research. The presentation contributes to the discussion of defining the teacher's role in school-based crisis interventions and dealing with high-intensity media coverage of war, terror, and catastrophes. THE PRESENTATION PROVIDES EDUCATIONAL AND PSYCHOLOGICAL PERSPECTIVES ON HOW TEACHERS CAN TAKE AN ACTIVE ROLE IN HELPING PUPILS TO DEAL WITH SUCH EVENTS THROUGH TWO APPROACHES: the therapeutic approach, to restore calm and feelings of safety; and the educational approach, to foster reflection and deeper understanding.

    Full Text Available [b]introduction and objective[/b]. Numerous epidemiologic studies have reported increased risk of allergic rhinitis and asthma in relation to ‘western life-style’, which represents diversity of factors. We hypothesized that residential proximity to major roadways, reflecting an exposure to traffic-related air pollution, is associated with prevalence of allergic respiratory symptoms in children. [b]materials and methods[/b]. A total of 8290 individuals of two age groups: 16 year olds and 7 year olds from Krakow, Poland were included. We used the Polish version of the International Study of Asthma and Allergy in Childhood supplemented with a question concerning the distance between a responder’s house and a high traffic density road: below 200 m, from 200–500 m, or more than 500 m. [b]results[/b]. Children and adolescents with a residential proximity closer to a major roadway had more frequent asthma-related symptoms in the last 12 months and at any time in the past. Consistent with the increased frequency of asthmatic symptoms, responders residing within 200 meters complained more often of sneezing, runny or blocked nose accompanied by itchy-watery eyes and hay fever in comparison to responders who resided 200–500 meters from a major roadway. The lowest rate of nasal symptoms was observed in residents living in the distance to major roads (> 500 meters. The rate of positive answers decreased in a distant-dependent manner. [b]conclusions[/b]. Our findings suggest an important spatial relationship between the distance from a major roadway and the evaluated respiratory symptoms. The results emphasize the need for more comprehensive air quality policies within urban areas with increased motor vehicle density.

    Full Text Available Traffic safety is a major concern in the transportation industry due to immense monetary and emotional burden caused by crashes of various severity levels, especially the injury and fatality ones. To reduce such crashes on all public roads, the safety management processes are commonly implemented which include network screening, problem diagnosis, countermeasure identification, and project prioritization. The selection of countermeasures for potential mitigation of crashes is governed by the influential factors which impact roadway crashes. Crash prediction model is the tool widely adopted by safety practitioners or researchers to link various influential factors to crash occurrences. Many different approaches have been used in the past studies to develop better fitting models which also exhibit prediction accuracy. In this study, a crash prediction model is developed to investigate the vehicular crashes occurring at roadway segments. The spatial and temporal nature of crash data is exploited to form a spatiotemporal model which accounts for the different types of heterogeneities among crash data and geometric or traffic flow variables. This study utilizes the Poisson lognormal model with random effects, which can accommodate the yearly variations in explanatory variables and the spatial correlations among segments. The dependency of different factors linked with roadway geometric, traffic flow, and road surface type on vehicular crashes occurring at segments was established as the width of lanes, posted speed limit, nature of pavement, and AADT were found to be correlated with vehicle crashes.

    The fire that occurred a the Creswell underground coal mine in Derbyshire in 1950 in which 90 miners lost their lives was caused by a damaged rubber conveyor belt that ignited after being friction heated. The fire propagated along the intake trunk roadway by the burning belt itself, which ignited the timber roadway supports and hampered fire-fighting efforts. This paper demonstrated that operating conveyors in intake trunk roadways presents a risk that products of combustion can be carried to the working areas of a mine via ventilation pathways, thus creating a hazard to the underground miners. In North America, the use of belt air is not commonly used to ventilate working areas. However, these arrangements are common in the United Kingdom. As such, installation, inspection and maintenance standards have been created to minimize the risk of fire in underground, remotely operated belt conveyors in underground mines. Monitoring systems are also in place for early detection of any fire. A review of recent underground fires in the United Kingdom has shown that the measures adopted have been successful in avoiding uncontrollable fires. 13 refs., 5 figs.

    Constructing the 3D virtual scene of a coal mine is the objective requirement for modernizing and processing information on coal mining production. It is also the key technology to establish a "digital mine". By exploring current worldwide research, software and hardware tools and application demands, combined with the case study site (the Dazhuang mine of Pingdingshan coal group), an approach for 3D geo-visualization of a mine surface plant and mine roadway is deeply discussed. In this study, the rapid modeling method for a large range virtual scene based on Arc/Info and SiteBuilder3D is studied, and automatic generation of a 3D scene from a 2D scene is realized. Such an automatic method which can convert mine roadway systems from 2D to 3D is realized for the Dazhuang mine. Some relevant application questions are studied, including attribute query, coordinate query, distance measure, collision detection and the dynamic interaction between 2D and 3D virtual scenes in the virtual scene of a mine surface plant and mine roadway. A prototype system is designed and developed.

    Storm water runoff from urban roadways contains anthropogenic pollutants, which are mainly generated from traffic-related activities. The purpose of this study was to evaluate the characteristics of pollutants from the roadway runoff as well as first flush effects. Storm water runoff was sampled during five storm events from the experimental site in Otsu, Shiga, Japan. From the hydrographs and pollutographs for the roadway runoff, the concentration of pollutants increased with increasing runoff flow in the low flow rate event, but did not significantly increase in the high flow rate event. Moreover, according to the analysis of cumulative pollutant mass versus runoff volume curves from five storm events, the first 50% of the runoff volume transported 62% of TOC and Mo, 60% of SS, 59% of Fe, Mn and Cu, 58% of Ni, 57% of Cd and Pb, 56% of Al, 55% of Zn, and 54% of Cr, as the mean values. The first 30% and 80% of the runoff volume also transported 34-43% mass of the pollutants and 82-88% mass of the pollutants, respectively. This study for storm water runoff may also provide useful information to correctly design treatment facilities, such as detention tanks and ponds, filtration and adsorption systems.

    Two different styles of grass swales were built in new Binhu region of Hefei city to monitor the flux and quality of the influent and effluent water under actual precipitation conditions, in order to evaluate the performance of water quality purification and pollution load control for roadway runoff. The results showed that both of the grass swales could effectively remove the pollutants such as TSS, COD, Pb, Cu, Cd, Zn in roadway runoff; the median EMC removal efficiencies of TSS and COD were 67.1%, 46.7% respectively,for facility I, and the median EMC removal efficiencies of TSS and COD were 78.6%, 58.6% respectively, for facility II; the concentrations of Pb, Cu, Zn in the effluent of facility II could meet the requirements of the surface water quality class V; release of nitrogen and phosphorus occurred in both facilities I and I[ in several rainfall events, mainly in heavy storms; the removal efficiencies of TP in the two grass swales were improved with the increase of influent concentration; the mean removal efficiencies of TP in facilities I and II were 14.7% and 45.4%, respectively; the load control performance of facility II for pollutants such as TSS, COD, TP, TN, NH4+ -N and NO3- -N was better than that of facility I; in the district with poor soil permeability and low ground slope, application of dry swale could achieve better performance in water quality control and pollution load reduction of roadway runoff.

  8. Evidence of Road Salt in New Hampshire’s Snowpack Hundreds of Meters from Roadways

    2017-07-01

    Full Text Available Salinization of surface and groundwater has been directly linked to the area of road surfaces in a watershed and the subsequent wintertime maintenance used to keep roads free of snow and ice. Most studies that explore road salt in snow along roadways limit the study to within 100 m from a roadway and conclude that there is negligible deposition of de-icing salt at distances greater than 100 m. In this study, we analyze the ion content of the southern New Hampshire snowpack and use Mg2+ as a conservative sea-salt tracer to calculate sea salt and non-sea salt fractions of Cl−. There is a minimum of 60% non-sea salt Cl−, which we attribute to road salt, in the snowpack at our study sites 115 to 350 m from the nearest maintained roadways. This suggests that larger areas need to be considered when investigating the negative impact of Cl− loading due to winter-time maintenance.

    Ethiopia lacks a complete vital registration system that would assist in measuring disease burden and risk factors. We used the Global Burden of Diseases, Injuries, and Risk Factors Study 2015 (GBD 2015) estimates to describe the mortality burden from communicable, non-communicable, and other diseases in Ethiopia over the last 25 years. GBD 2015 mainly used cause of death ensemble modeling to measure causes of death by age, sex, and year for 195 countries. We report numbers of deaths and rates of years of life lost (YLL) for communicable, maternal, neonatal, and nutritional (CMNN) disorders, non-communicable diseases (NCDs), and injuries with 95% uncertainty intervals (UI) for Ethiopia from 1990 to 2015. CMNN causes of death have declined by 65% in the last two-and-a-half decades. Injury-related causes of death have also decreased by 70%. Deaths due to NCDs declined by 37% during the same period. Ethiopia showed a faster decline in the burden of four out of the five leading causes of age-standardized premature mortality rates when compared to the overall sub-Saharan African region and the Eastern sub-Saharan African region: lower respiratory infections, tuberculosis, HIV/AIDS, and diarrheal diseases; however, the same could not be said for ischemic heart disease and other NCDs. Non-communicable diseases, together, were the leading causes of age-standardized mortality rates, whereas CMNN diseases were leading causes of premature mortality in 2015. Although lower respiratory infections, tuberculosis, and diarrheal disease were the leading causes of age-standardized death rates, they showed major declines from 1990 to 2015. Neonatal encephalopathy, iron-deficiency anemia, protein-energy malnutrition, and preterm birth complications also showed more than a 50% reduction in burden. HIV/AIDS-related deaths have also decreased by 70% since 2005. Ischemic heart disease, hemorrhagic stroke, and ischemic stroke were among the top causes of premature mortality and age

    The recent push to develop unconventional sources of oil and gas both in the U.S. and abroad via hydraulic fracturing (“fracking”) has generated a great deal of controversy. Effectively engaging stakeholders and setting appropriate policies requires insights into current public perceptions of this issue. Using a nationally representative U.S. sample (N=1061), we examine public perceptions of hydraulic fracturing including: “top of mind” associations; familiarity with the issue; levels of support/opposition; and predictors of such judgments. Similar to findings on other emerging technologies, our results suggest limited familiarity with the process and its potential impacts and considerable uncertainty about whether to support it. Multiple regression analysis (r 2 =.49) finds that women, those holding egalitarian worldviews, those who read newspapers more than once a week, those more familiar with hydraulic fracturing, and those who associate the process with environmental impacts are more likely to oppose fracking. In contrast, people more likely to support fracking tend to be older, hold a bachelor's degree or higher, politically conservative, watch TV news more than once a week, and associate the process with positive economic or energy supply outcomes. Based on these findings, we discuss recommendations for future research, risk communication, and energy policy. - Highlights: • We conducted a survey of Americans' views on hydraulic fracturing in September 2012. • A majority of Americans have heard little or nothing about hydraulic fracturing. • Many Americans do not know if they support/oppose it or are undecided. • Those who have made a decision are evenly split between support and opposition. • Predictors of support include education, media use and top of mind associations

  13. The Use of the International Nuclear and Radiological Event Scale (INES) for Event Communication. Guidelines and Good Practices for Setting up a National Framework on the Effective Use of INES for Event Communication

    International Nuclear Information System (INIS)

    2014-10-01

    The IAEA’s International Nuclear and Radiological Event Scale (INES) was developed in 1990 by international experts convened by the IAEA and the OECD Nuclear Energy Agency with the aim of communicating the safety significance of events at nuclear installations. Since then, INES has been expanded to meet the growing need for communicating the safety significance of events giving rise to radiation risk. At present, INES is used for communicating to the public, in a consistent way, the safety significance of an event associated with sources of radiation, whether or not the event occurs at a facility. INES covers a wide spectrum of practices, including industrial uses such as gammagraphy, the use of sources of radiation in medicine, activities at nuclear power plants and research reactors, activities at spent nuclear fuel and radioactive waste management facilities, and the transport of radioactive material. INES has become a widely used tool for putting the safety significance of radiation events into proper perspective. The number of countries using INES has risen steadily over the past five years. As a result, there is a need to ensure the harmonized application of this scale worldwide. Up to now, international activities regarding INES have focused more on developing guidance on rating events than on the ways of using INES. This publication is the first to provide guidance on establishing or improving a national framework for the effective use of INES during event communication. It has been prepared on the basis of national experience with communicating events that have occurred since the introduction of INES. This publication also includes, in Annex I, lessons learned from the application of INES during and after the accident at the Fukushima Daiichi nuclear power plant, Guidance on the Use of INES in Evolving Severe Accidents

  14. Modelling the Small Throw Fault Effect on the Stability of a Mining Roadway and Its Verification by In Situ Investigation

    2017-12-01

    Full Text Available The small throw fault zones cause serious problems for mining engineers. The knowledge about the range of fractured zone around the roadway and about roadway’s contour deformations helps a lot with the right support design or its reinforcement. The paper presents the results of numerical analysis of the effect of a small throw fault zone on the convergence of the mining roadway and the extent of the fracturing induced around the roadway. The computations were performed on a dozen physical models featuring various parameters of rock mass and support for the purpose to select the settings that reflects most suitably the behavior of tectonically disturbed and undisturbed rocks around the roadway. Finally, the results of the calculations were verified by comparing them with in situ convergence measurements carried out in the maingate D-2 in the “Borynia-Zofiówka-Jastrzębie” coal mine. Based on the results of measurements it may be concluded that the rock mass displacements around a roadway section within a fault zone during a year were four times in average greater than in the section tectonically unaffected. The results of numerical calculations show that extent of the yielding zone in the roof reaches two times the throw of the fault, in the floor 3 times the throw, and horizontally approx. 1.5 to 1.8 times the width of modelled fault zone. Only a few elasto-plastic models or models with joints between the rock beds can be recommended for predicting the performance of a roadway which is within a fault zone. It is possible, using these models, to design the roadway support of sufficient load bearing capacity at the tectonically disturbed section.

    The New Zealand Government is committed to playing its part in the global response to climate change. This Fourth National Communication provides a snapshot of New Zealand's progress with implementing the United Nations Framework Convention on Climate Change (UNFCCC). This document covers the period from the submission of the Third National Communication in January 2002 through to the end of December 2005. This document also contains New Zealand's Report on the Global Climate Observing System and the Report on Demonstrable Progress under the Kyoto Protocol. New Zealand's response to climate change has evolved substantially since the Third National Communication was submitted. On 19 December 2002, New Zealand became the 101st nation to ratify the Kyoto Protocol. In 2002, the New Zealand Parliament passed the Climate Change Response Act. This Act established a New Zealand climate change registry and corresponding institutional arrangements in accordance with Kyoto Protocol requirements. Other achievements are detailed throughout this Fourth National Communication. When the Government introduced its climate change policy package in 2002, it anticipated there would be three reviews of the package not later than 2005, 2007 and 2010. The reviews would be necessary to monitor progress with emissions reductions, assess the effectiveness of policies, and confirm that New Zealand was positioned to meet its commitments. The first of these reviews was commissioned by the Government in mid-2005 and completed by November 2005. The review concluded that some elements of the Government's 2002 climate change policy package should be modified to better position New Zealand to respond to the longer-term challenges of climate change. A key outcome of the policy review was the announcement by the newly elected Government in December 2005 that the previously announced carbon tax would not proceed. In addition, a suite of future work programmes would be required to inform Government

Using information on the scientific production of the different research institutes and centres published in the annual reports of the UNAM from 1997-2000 and analysing its presence in regional and international databases from 1997-1999, it was possible to establish the basis for the development of models in five main areas of knowledge: Exact Sciences; Natural Sciences; Applied Sciences; Social Sciences and the Humanities. Researchers from the first three areas published mainly in articles from international, peer-reviewed journals and, consequently, their production was highly visible in mainstream databases. On the other hand, researchers from the social sciences and humanities give equal weight to publication in books and in book chapters as they do to publication in journals. Unlike researchers in the hard sciences, social scientists and those working in the humanities prefer regional journals as shown by a strong presence in regional databases and low representation in the international databases. Therefore we conclude that communication patterns are different between the main areas of knowledge as previously defined.

    Doctor-patient communication is a key driver of overall satisfaction with primary care. Patients from minority ethnic backgrounds consistently report more negative experiences of doctor-patient communication. However, it is currently unknown whether these ethnic differences are concentrated in one gender or in particular age groups. To determine how reported GP-patient communication varies between patients from different ethnic groups, stratified by age and gender. Analysis of data from the English GP Patient Survey from 2012-2013 and 2013-2014, including 1,599,801 responders. A composite score was created for doctor-patient communication from five survey items concerned with interpersonal aspects of care. Mixed-effect linear regression models were used to estimate age- and gender-specific differences between white British patients and patients of the same age and gender from each other ethnic group. There was strong evidence (Pcommunication varied by both age and gender. The difference in scores between white British and other responders on doctor-patient communication items was largest for older, female Pakistani and Bangladeshi responders, and for younger responders who described their ethnicity as 'Any other white'. The identification of groups with particularly marked differences in experience of GP-patient communication--older, female, Asian patients and younger 'Any other white' patients--underlines the need for a renewed focus on quality of care for these groups. © British Journal of General Practice 2016.

  20. Assessing roadway contributions to stormwater flows, concentrations, and loads with the StreamStats application

    2018-01-01

    The Oregon Department of Transportation (ODOT) and other state departments of transportation need quantitative information about the percentages of different land cover categories above any given stream crossing in the state to assess and address roadway contributions to water-quality impairments and resulting total maximum daily loads. The U.S. Geological Survey, in cooperation with ODOT and the FHWA, added roadway and land cover information to the online StreamStats application to facilitate analysis of stormwater runoff contributions from different land covers. Analysis of 25 delineated basins with drainage areas of about 100 mi2 indicates the diversity of land covers in the Willamette Valley, Oregon. On average, agricultural, developed, and undeveloped land covers comprise 15%, 2.3%, and 82% of these basin areas. On average, these basins contained about 10 mi of state highways and 222 mi of non-state roads. The Stochastic Empirical Loading and Dilution Model was used with available water-quality data to simulate long-term yields of total phosphorus from highways, non-highway roadways, and agricultural, developed, and undeveloped areas. These yields were applied to land cover areas obtained from StreamStats for the Willamette River above Wilsonville, Oregon. This analysis indicated that highway yields were larger than yields from other land covers because highway runoff concentrations were higher than other land covers and the highway is fully impervious. However, the total highway area was a fraction of the other land covers. Accordingly, highway runoff mitigation measures can be effective for managing water quality locally, they may have limited effect on achieving basin-wide stormwater reduction goals.

    Full Text Available Based on finite difference method, a mathematical model and a numerical model written by Fortran language were established in the paper. Then a series of experiments were conducted to figure out the evolution law of temperature field in high geothermal roadway. Research results indicate that temperature disturbance range increases gradually as the unsteady heat conduction goes on and it presents power function relationship with dimensionless time. Based on the case analysis, there is no distinct expansion of temperature disturbance range after four years of ventilation, when the temperature disturbance range R=13.6.

  2. Technical Feasibility Assessment of LED Roadway Lighting on the Golden Gate Bridge

    2012-09-01

    Subsequent to preliminary investigations by the Golden Gate Bridge Highway & Transportation District (GGB), in coordination with Pacific Gas & Electric (PG&E), the GATEWAY Demonstration program was asked to evaluate the technical feasibility of replacing existing roadway lighting on the bridge with products utilizing LED technology. GGB and PG&E also indicated interest in induction (i.e., electrodeless fluorescent) technology, since both light source types feature rated lifetimes significantly exceeding those of the existing high-pressure sodium (HPS) and low-pressure sodium (LPS) products. The goal of the study was to identify any solutions which would reduce energy use and maintenance without compromising the quantity or quality of existing illumination. Products used for roadway lighting on the historic bridge must be installed within the existing amber-lensed shoebox-style luminaire housings. It was determined that induction technology does not appear to represent a viable alternative for the roadway luminaires in this application; any energy savings would be attributable to a reduction in light levels. Although no suitable LED retrofit kits were identified for installation within existing luminaire housings, several complete LED luminaires were found to offer energy savings of 6-18%, suggesting custom LED retrofit kits could be developed to match or exceed the performance of the existing shoeboxes. Luminaires utilizing ceramic metal halide (CMH) were also evaluated, and some were found to offer 28% energy savings, but these products might actually increase maintenance due to the shorter rated lamp life. Plasma technology was evaluated, as well, but no suitable products were identified. Analysis provided in this report was completed in May 2012. Although LED technologies are expected to become increasingly viable over time, and product mock-ups may reveal near-term solutions, some options not currently considered by GGB may ultimately merit evaluation.

    To examine the availability of national information and communication technology (ICT) or eHealth policies produced by countries in Latin America and the Caribbean (LAC), and to determine the influence of a country's socioeconomic context on the existence of these policies. Documents describing a national ICT or eHealth policy in any of the 33 countries belonging to the LAC region as listed by the United Nations were identified from three data sources: academic databases; the Google search engine; and government agencies and representatives. The relationship between the existence of a policy and national socioeconomic indicators was also investigated. There has been some progress in the establishment of ICT and eHealth policies in the LAC region. The most useful methods for identifying the policies were 1) use of the Google search engine and 2) contact with Pan American Health Organization (PAHO) country representatives. The countries that have developed a national ICT policy seem to be more likely to have a national eHealth policy in place. There was no statistical significant association between the existence of a policy and a country's socioeconomic context. Governments need to make stronger efforts to raise awareness about existing and planned ICT and eHealth policies, not only to facilitate ease of use and communication with their stakeholders, but also to promote collaborative international efforts. In addition, a better understanding of the effect of economic variables on the role that ICTs play in health sector reform efforts will help shape the vision of what can be achieved.

    The NASA DEVELOP National Program conducts over eighty Earth science projects every year. Each project applies NASA Earth observations to impact decision-making related to a local or regional community concern. Small, interdisciplinary teams create a methodology to address the specific issue, and then pass on the results to partner organizations, as well as providing them with instruction to continue using remote sensing for future decisions. Many different methods are used by individual teams, and the program as a whole, to communicate results and research accomplishments to decision-makers, stakeholders, alumni, and the general public. These methods vary in scope from formal publications to more informal venues, such as social media. This presentation will highlight the communication techniques used by the DEVELOP program. Audiences, strategies, and outlets will be discussed, including a newsletter, microjournal, video contest, and several others.

  5. Remote sensing-based detection and quantification of roadway debris following natural disasters

    2016-05-01

    Rapid knowledge of road network conditions is vital to formulate an efficient emergency response plan following any major disaster. Fallen buildings, immobile vehicles, and other forms of debris often render roads impassable to responders. The status of roadways is generally determined through time and resource heavy methods, such as field surveys and manual interpretation of remotely sensed imagery. Airborne lidar systems provide an alternative, cost-effective option for performing network assessments. The 3D data can be collected quickly over a wide area and provide valuable insight about the geometry and structure of the scene. This paper presents a method for automatically detecting and characterizing debris in roadways using airborne lidar data. Points falling within the road extent are extracted from the point cloud and clustered into individual objects using region growing. Objects are classified as debris or non-debris using surface properties and contextual cues. Debris piles are reconstructed as surfaces using alpha shapes, from which an estimate of debris volume can be computed. Results using real lidar data collected after a natural disaster are presented. Initial results indicate that accurate debris maps can be automatically generated using the proposed method. These debris maps would be an invaluable asset to disaster management and emergency response teams attempting to reach survivors despite a crippled transportation network.

    2007-01-01

    Air quality is a serious and worsening problem in the rapidly growing cities of sub-Saharan Africa (SSA). However, the lack of ambient monitoring data, and particularly urban roadside concentrations for particulate matter in SSA cities severely hinders our ability to describe temporal and spatial patterns of concentrations, characterize exposure-response relationships for key health outcomes, estimate disease burdens, and promote policy initiatives to address air quality. As part of a collaborative transportation planning exercise between Columbia University and University of Nairobi, air monitoring was carried out in February 2006 in Nairobi, Kenya. The objective of the monitoring was to collect pilot data on air concentrations (PM 2.5 and black carbon) encountered while driving in the Nairobi metropolitan area, and to compare those data to simultaneous 'urban background' concentrations measured in Nairobi but away from roadways. For both the background and roadway monitoring, we used portable air sampling systems that collect integrated filter samples. Results from this pilot study found that roadway concentrations of PM 2.5 were approximately 20-fold higher than those from the urban background site, whereas black carbon concentrations differed by 10-fold. If confirmed by more extensive sampling, these data would underscore the need for air quality and transportation planning and management directed at mitigating roadway pollution

    Few studies examine urban air pollution in sub-Saharan Africa (SSA), yet urbanization rates there are among the highest in the world. In this study, we measured 8-hr average occupational exposure levels of fine particulate matter (PM2.5), black carbon (BC), ultra violet active-particulate matter (UV-PM), and trace elements for individuals who worked along roadways in Nairobi, specifically bus drivers, garage workers, street vendors, and women who worked inside informal settlements. We found BC and re-suspended dust were important contributors to PM2.5 levels for all study populations, particularly among bus drivers, while PM2.5 exposure levels for garage workers, street vendors, and informal settlement residents were not statistically different from each other. We also found a strong signal for biomass emissions and trash burning, which is common in Nairobi’s low-income areas and open-air garages. These results suggest that the large portion of urban residents in SSA who walk along roadways would benefit from air quality regulations targeting roadway emissions from diesel vehicles, dust, and trash burning. This is the first study to measure occupational exposure to urban air pollution in SSA and results imply that roadway emissions are a serious public health concern. PMID:26034383

    The NASA Langley Research Center has transformed a Cirrus Design SR22 general aviation (GA) aircraft into an Unmanned Aerial Systems (UAS) Surrogate research aircraft which has served for several years as a platform for unmanned systems research and development. The aircraft is manned with a Safety Pilot and a Research Systems Operator (RSO) that allows for flight operations almost any-where in the national airspace system (NAS) without the need for a Federal Aviation Administration (FAA) Certificate of Authorization (COA). The UAS Surrogate can be remotely controlled from a modular, transportable ground control station (GCS) like a true UAS. Ground control of the aircraft is accomplished by the use of data links that allow the two-way passage of the required data to control the aircraft and provide the GCS with situational awareness. The original UAS Surrogate data-link system was composed of redundant very high frequency (VHF) data radio modems with a maximum range of approximately 40 nautical miles. A new requirement was developed to extend this range beyond visual range (BVR). This new requirement led to the development of a satellite communications system that provided the means to command and control the UAS Surrogate at ranges beyond the limits of the VHF data links. The system makes use of the Globalstar low earth orbit (LEO) satellite communications system. This paper will provide details of the development, implementation, and flight testing of the satellite data communications system on the UAS Surrogate research aircraft.

    2017-11-01

    Determination of the effect of vehicle emissions on air quality near roadways is important because vehicles are a major source of air pollution. A near-roadway monitoring program was undertaken in Chicago between August 4 and October 30, 2014, to measure ultrafine particles, carbon dioxide, carbon monoxide, traffic volume and speed, and wind direction and speed. The objective of this study was to develop a method to relate short-term changes in traffic mode of operation to air quality near roadways using data averaged over 5-min intervals to provide a better understanding of the processes controlling air pollution concentrations near roadways. Three different types of data analysis are provided to demonstrate the type of results that can be obtained from a near-roadway sampling program based on 5-min measurements: (1) development of vehicle emission factors (EFs) for ultrafine particles as a function of vehicle mode of operation, (2) comparison of measured and modeled CO 2 concentrations, and (3) application of dispersion models to determine concentrations near roadways. EFs for ultrafine particles are developed that are a function of traffic volume and mode of operation (free flow and congestion) for light-duty vehicles (LDVs) under real-world conditions. Two air quality models-CALINE4 (California Line Source Dispersion Model, version 4) and AERMOD (American Meteorological Society/U.S. Environmental Protection Agency Regulatory Model)-are used to predict the ultrafine particulate concentrations near roadways for comparison with measured concentrations. When using CALINE4 to predict air quality levels in the mixing cell, changes in surface roughness and stability class have no effect on the predicted concentrations. However, when using AERMOD to predict air quality in the mixing cell, changes in surface roughness have a significant impact on the predicted concentrations. The paper provides emission factors (EFs) that are a function of traffic volume and mode of

    The forced-exhaust ventilation is an important way to control the concentration of radon and its progenies in long-distance blind driving roadway. It is of great significance for guiding the design of ventilation and radiation protection to study distribution characteristics of the concentration of radon and its progenies in the wind of roadway adopting the forced-exhaust ventilation. Therefore, according to the decay relationship of radon and its progenies, a simplified mathematical calculation model was built, which relates to the radon activity concentration and the potential alpha concentration of radon progenies. The paper also analyzed the sources of radon and its progenies in the limited space of the blind roadway. Then, based on the turbulence mass transfer theory of ventilation air flow, the paper established mathematical calculation models of distribution characteristics of the radon activity concentration and the potential alpha concentration of radon progenies in blind roadway with forced-exhaust ventilation, respectively. Finally, the paper applied the calculation models to a special blind roadway, and discussed the influence of the ventilation air inflow and the radon exhalation rate of rock wall on the distribution of radon concentration and the potential alpha concentration of radon progenies in the roadway. Meanwhile, some protective measurements were put forward to reduce the radiation dose of worker caused by radon and its progenies in the blind roadway. (authors)

    This report provides a reference source for the design of ground control measures in coal mine roadways using analytical methods. Collapse models are provided for roof and rib. The roof models recognise that different collapse modes can apply in different stress fields - high, intermediate, and zero compressive stresses. The rib models draw analogies to rock slope stability and also the impact of high vertical stresses. Methods for determining support or reinforcement requirements are provided. Suspension of collapsed masses is identified as the basis for roof support in both very high and zero compressive stress regimes. Reinforcement of bedding discontinuities is advocated for intermediate compressive stresses. For the ribs, restraint of coal blocks defined by pre-existing joints or by mining induced fractures is required.

    2018-01-01

    Longwall top-coal caving (LTCC) has been a popular, more productive and cost-effective method for extracting thick (> 5 m) to ultra-thick coal seams in recent years. However, low-level recovery ratio of coal resources and top-coal loss above the supports at both ends of working face are long-term problems. Geological factors, such as large dip angle, soft rock, mining depth further complicate the problems. This paper proposes addressing this issue by adopting three-dimensional roadway layout of stagger arrangement (3-D RLSA). In this study, the first step was to analyse the stress environment surrounding head entry in the replacing working face based on the stress distribution characteristics at the triangular coal-pillar side in gob and the stress slip line field theory. In the second step, filed observation was conducted. Finally, an economic evaluation of the 3-D RLSA for extracting thick to ultra-thick seams was conducted.

    2015-01-01

    Full Text Available Using UDEC discrete element numerical simulation software and a cosine wave as vibration source, the whole process of rockburst failure and the propagation and attenuation characteristics of shock wave in coal-rock medium were investigated in detail based on the geological and mining conditions of 1111(1 working face at Zhuji coal mine. Simultaneously, by changing the thickness and strength of immediate roof overlying the mining coal seam, the whole process of rockburst failure of roadway and the attenuation properties of shock wave were understood clearly. The presented conclusions can provide some important references to prevent and control rockburst hazards triggered by shock wave interferences in deep coal mines.

  8. Analysis of Roadway Traffic Accidents Based on Rough Sets and Bayesian Networks

    Full Text Available The paper integrates Rough Sets (RS and Bayesian Networks (BN for roadway traffic accident analysis. RS reduction of attributes is first employed to generate the key set of attributes affecting accident outcomes, which are then fed into a BN structure as nodes for BN construction and accident outcome classification. Such RS-based BN framework combines the advantages of RS in knowledge reduction capability and BN in describing interrelationships among different attributes. The framework is demonstrated using the 100-car naturalistic driving data from Virginia Tech Transportation Institute to predict accident type. Comparative evaluation with the baseline BNs shows the RS-based BNs generally have a higher prediction accuracy and lower network complexity while with comparable prediction coverage and receiver operating characteristic curve area, proving that the proposed RS-based BN overall outperforms the BNs with/without traditional feature selection approaches. The proposed RS-based BN indicates the most significant attributes that affect accident types include pre-crash manoeuvre, driver’s attention from forward roadway to centre mirror, number of secondary tasks undertaken, traffic density, and relation to junction, most of which feature pre-crash driver states and driver behaviours that have not been extensively researched in literature, and could give further insight into the nature of traffic accidents.

  10. COMMUNICATING THE STEREOTYPE OF “OTHERNESS” IN EUROPEAN ADVERTISING: CULTURAL AND NATIONAL “FAKE MULTICULTURALISM”

    Full Text Available In its quest for the destination of an ‘all-encompassing’ communication, European advertising builds an image of complexity and oppositions. Constructed as a mingling of cultural values, intensive consumerism and creative touches, the story of advertising is a never-ending analysis of nowadays globalized societies. Moreover, its ramifying story of acceptance, assimilation, rejection and stereotypy brought advertising at a position in which the debate over intercultural representation and consumer behavior is crucial. Consequently, the main question that arises is: in the realm of the thirsty and goods-addict consumers, what type of discourse should advertising in Europe use, so as to emphasize pluralism and still maintain culturally personalized approaches. It is, therefore, the purpose of this paper to explore and analyze the congruencies and disparities between advertising and its social, cultural and economic repositories, on the background of Europe’s image. In this respect, some questions can be formulated: How does advertising pertain to organizing its communication with the overly globalized consumer markets? Is the stereotypical label hereby inserted in such a communicational direction with consumers, and if so, what are the features of an “addressing otherness” discourse with respect to ad typology? Another aim of the current paper is to evoke the level at which European advertising fails to stick to the intercultural framework of reference, through a presentation of the stereotypes of “otherness” and the implied “fake multiculturalism.” The idea behind this assumption is that, while representing ethnic groups differently or by use of a derogatory mechanism, the message cannot be that of Europeanness. Moreover, the focus on linguistic choice of advertising vocabulary is linked to the issue of “linguistic fetishism” and, more importantly, it shows that the variety of linguistic panel in Europe sometimes prevents

    Access to medicines is a universal right. Low availability and low affordability of medicines are issues that deny this right to a significant proportion of the world population. The objective of this study was to determine the availability, price and affordability of essential medicines prescribed to treat non communicable diseases in Sri Lanka. Methodology was based on the 2nd edition of the World Health Organization Health Action International Manual. A country survey was conducted and facilities representing both public and private pharmacies were selected. A total of 109 facilities was surveyed. At each facility data on the availability and prices of 50 essential medicines for non communicable diseases were collected. Percentage availability, median price of originator brand and lowest priced generic, median price ratio to the International Reference Price were calculated for surveyed medicines. Affordability was determined using the daily incomes of the lowest--paid unskilled government worker. Semi government community pharmacies had the highest (>80%) availability while outdoor pharmacies of public health care facilities, private pharmacies and outdoor pharmacies of private hospital showed a fairly high availability (50 - 80%) of surveyed medicines.Unit price of 76% of selected individual medicines was less than ten Sri Lankan rupees. Out of these 28% of medicines cost less than one Sri Lanka rupee. For 21 of the surveyed medicines the median price ratio to the international reference price was less than one. The prices of originator brands for 14 surveyed medicines were more than five times that of the lowest price generics.Less than a single day's wages was adequate to purchase a month's supply of the lowest priced generic of more than 67% of surveyed medicines. The availability of selected essential medicines was fairly high in both public and private sectors in Sri Lanka. Most medicines are affordable to the lowest income earners in the community. There

    Earthquake Early Warning (EEW) systems can provide as much as tens of seconds of warning to people and automated systems before strong shaking arrives. The United States Geological Survey (USGS) and its partners are developing an EEW system for the West Coast of the United States. To be an integral part of successful implementation, EEW engagement programs and materials must integrate with and leverage broader earthquake risk programs. New methods and products for dissemination must be multidisciplinary, cost effective, and consistent with existing hazards education efforts. Our presentation outlines how the USGS and its partners will approach this effort in the context of the EEW system through the work of a multistate and multiagency committee that participates in the design, implementation, and evaluation of a portfolio of programs and products. This committee, referred to as the ShakeAlert Joint Committee for Communication, Education, and Outreach (ShakeAlert CEO), is working to identify, develop, and cultivate partnerships with EEW stakeholders including Federal, State, academic partners, private companies, policy makers, and local organizations. Efforts include developing materials, methods for delivery, and reaching stakeholders with information on EEW, earthquake preparedness, and emergency protective actions. It is essential to develop standards to ensure information communicated via the EEW alerts is consistent across the public and private sector and achieving a common understanding of what actions users take when they receive an EEW warning. The USGS and the participating states and agencies acknowledge that the implementation of EEW is a collective effort requiring the participation of hundreds of stakeholders committed to ensuring public accessibility.

    Dog-related human injuries affect public safety and animal welfare, and occur more frequently in rural, remote, and Indigenous communities than in urban centres in Canada. Little work has been done to identify the perspectives of those people most heavily affected by this issue or to report successful dog management programs. This project was undertaken by veterinarians and public health workers with the goal of documenting First Nations perspectives on dogs, and educating other rural health workers about introducing animal management services to Indigenous communities. We recruited 10-14 residents and healthcare workers from three First Nations to take dog-related photos in their communities and participate in group interviews during the summer of 2014. Audiovisual data were synthesised into four digital stories exploring the following aspects of participant relationships with community dogs: (1) Spay/neuter clinics; (2) Role of the dog (past and present); (3) Human-animal bond; and (4) Healthy dogs as a part of healthy communities. These videos document changes in dog husbandry behaviour, new acceptance of spay/neuter, three-way knowledge transfer between residents, researchers, and policy makers, and an overall desire to sustain the positive outcomes of the pilot dog management project. This work highlights cultural beliefs and success strategies that might guide other programs providing veterinary services in First Nations communities.

    Objective: To investigate the current status of prevalence, treatment, and management on hypertension among Chinese adults from the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases. Methods: We selected a total of 4 000 residents aged ≥18 years for this questionnaire-based survey by multi-stage clustering sampling in 10 National Demonstration Areas between November and December, 2016. Results: There were 3 891 effective questionnaires. The self-reported prevalence of hypertension among aged ≥35 years was 31.47% (1 011/3 213). For the past two weeks, the self-reported treatment of hypertension was 86.75%(877/1 011), with the rates of guidance as 56.87% (575/1 011) on physical activity, 40.95% (414/1 011) on diet, 38.33% (385/1 011) on weight management, and 22.75% (228/1 011) on smoking cessation. For the past 12 months, 74.68% (755/1 011) of the residents aged ≥35 years were under the proper management and 62.12% (628/1 011) of them were under the standardized management programs. The follow-up program lasted for 4 ( P(25) - P(75) : 4-12) times per year, with 15 ( P(25) - P(75) : 10-20) minutes per each visit. Hypertensive patients would mainly visit the outpatient clinics (53.51%), followed by home visits (22.91%) and telephone calls (13.64%). Rate of satisfaction on management services was 94.83% (716/755) from the hypertensive patients. Multivariate analysis showed that the rate of self-reported treatment ( OR =1.986, 95% CI : 1.222-3.228) and self-reported standardized management ( OR =2.204, 95% CI : 1.519-3.199) on hypertension were higher in the Demonstration Areas with higher implementation scores of self-reported non-communicable diseases management. Conclusions: Prevention and management on hypertension in the Demonstration Areas had met the requirement set for the Demonstration Areas during the "12th Five-Year Plan" .

    Telehealth professionals require advanced communication skills, in part to compensate for lack of visual cues. Teach-Back is a best practice communication technique that has been recommended but not previously evaluated for consumer telehealth. We aimed to implement Teach-Back at a national maternal and child health telephone helpline. We describe the intervention and report telenurse experiences learning to use Teach-Back. We identified barriers (time, knowledge, skills, beliefs) and enablers (self-reflection) to using Teach-Back, and developed a novel training program to address these, guided by the Theoretical Domains Framework. We engaged maternal and child health telenurses to participate in a "communication skills" study. The intervention had two key components: guided self-reflection and a Teach-Back skills workshop. For the duration of the 7-week study nurses completed brief online surveys following each call, reflecting on both the effectiveness of their communication and perceived caller understanding. At the end of each shift they reflected on what worked well. Teach-Back knowledge, skills, and beliefs were addressed in a 2-h workshop using videos, discussion, and role play. We explored nurses' experiences of the intervention in focus groups and interviews; and analysed transcripts and comments from the self-reflection surveys using the Framework method. This study forms part of a larger evaluation conducted in 2016. In total 16 nurses participated: 15 were trained in Teach-Back, and 13 participated in focus groups or interviews. All engaged with both self-reflection and Teach-Back, although to differing extents. Those who reported acquiring Teach-Back skills easily limited themselves to one or two Teach-Back phrases. Nurses reported that actively self-reflecting (including on what they did well) was useful both for developing Teach-Back skills and analysing effectiveness of the techniques. Most wanted more opportunity to learn how their colleagues

    This study aimed to determine the use and perceptions towards information and communication technologies (ICT) in 206 patients with arterial hypertension, dyslipidemia and diabetes, recruited from the outpatient clinic in a national hospital in Lima, Peru. 54.4% were older adults and 70.4% were women. The use of daily phone calls was 44.7%. Most had never used a computer (78.2%), email (84%) or the Internet (84%). Many have never sent (80.6%) or received (69.9%) a text message. 70% had at some time forgotten to take their medicine. 72.8% would like to be reminded to take their medication and 67.9% had a family member who could help them with access to ICT. Despite the low use of ICT in this population, there is willingness and expectation from the patients to participate in programs that implement them.

    We proposed a conceptual model to predict health information-seeking behaviors (HISBs) from three different sources (family, the Internet, doctors). To test the model, a structural equation modeling (SEM) analysis was conducted using data from the 2012 Annenberg National Health Communication Survey (ANHCS) (N = 3,285). Findings suggest higher social support from family predicts higher trust in health information from family members (abbreviated as trust in this article). Trust is positively related to HISBs from all three sources, with the path linking trust to HISB from family being the strongest. The effect of social support on HISB from family is partially mediated by trust, while effect of social support on HISBs from the Internet/doctors is fully mediated by trust. Implications of the study are discussed.

    The communication of work accident is the document which warrants to the worker who suffered an accident the right to social benefit, and also serves as a source of epidemiological data. This study described the work accidents notified to the National Institute of Social Security of Santa Maria, RS, Brazil, in the year of 2000, attributing to them classifications that could be compared to Brazilian data and similar studies, among those the kind of accident, production sector and the worker's days off. It was possible to evidence the significant increase of notifications registered during the year of 2000 in relation to 1999, beyond the sub-register, specially in the scope of less serious accidents.

    In this study, an investigation of 231 articles of the oral communication sections presented at the National Symposium on Physics Teaching (NSPT) was conducted, trying to identify those related to Information and Communication Technology (ICT), its form of organization, the involved thematic areas and the degree of teaching, allowing to compare the different perspectives and trends in this field. The conducted state of the art-study had a bibliographical character and qualitative contours involving content analysis. It was realized that the thematic area "Information technology, technology diffusion and Physics teaching", where most of the research related to ICT is concentrated, represent 11.7% of the total number of papers at the XIX NSPT, confirming a trend of research in this area. It was found, among other things, the predominance of studies where learning objects are used in Physics Education, especially in High School and University Education; the use of ICT in multidisciplinary work and that some features need to be further explored, such as thermodynamics. It was also noted an expressive amount of studies involving the use of ICT in teacher training proposals, which can contribute to the enlargement of the methodological options of teachers and meet their training needs.

    This report describes the process and results of a demonstration of solid-state lighting (SSL) technology conducted in 2009 at the recently reconstructed I-35W bridge in Minneapolis, MN. The project was supported under the U.S. Department of Energy (DOE) Solid-State Lighting GATEWAY Technology Demonstration Program. Other participants in the demonstration project included the Minnesota Department of Transportation (Mn/DOT), Federal Highways Administration (FHWA), and BetaLED™ (a division of Ruud Lighting). Pacific Northwest National Laboratory (PNNL) conducted the measurements and analysis of the results. DOE has implemented a three-year evaluation of the LED luminaires in this installation in order to develop new longitudinal field data on LED performance in a challenging, real-world environment. This document provides information through the initial phase of the I-35W bridge project, up to and including the opening of the bridge to the public and the initial feedback received on the LED lighting installation from bridge users. Initial findings of the evaluation are favorable, with minimum energy savings level of 13% for the LED installation relative to the simulated base case using 250W high-pressure sodium (HPS) fixtures. The LEDs had an average illuminance level of 0.91 foot candles compared to 1.29 fc for the HPS lamps. The LED luminaires cost $38,000 more than HPS lamps, yielding a lengthy payback period, however the bridge contractor had offered to include the LED luminaires as part of the construction package at no additional cost. One potentially significant benefit of the LEDs in this installation is avoiding rolling lane closures on the heavily-traveled interstate bridge for the purpose of relamping the HPS fixtures. Rolling lane closures involve multiple crew members and various maintenance and safety vehicles, diversion of traffic, as well as related administrative tasks (e.g., approvals, scheduling, etc.). Mn/DOT records show an average cost of

    All-terrain vehicles (ATVs) are designed for off-highway use only, and many of their features create increased risk with roadway travel. Over half of all ATV-related fatalities occur on roadways, and nonfatal roadway crashes result in more serious injuries than those off the road. A number of jurisdictions have passed or have considered legislation allowing ATVs on public roadways, sometimes limiting them to those unpaved, arguing that they are safe for ATVs. However, no studies have determined the epidemiology of ATV-related fatalities on different road surface types. The objective of the study was to compare ATV-related deaths on paved versus unpaved roads and to contrast them with off-road fatalities. Retrospective descriptive and multivariable analyses were performed using U.S. Consumer Product Safety Commission fatality data from 1982 through 2012. After 1998, ATV-related deaths increased at twice the rate on paved versus unpaved roads. Still, 42% of all roadway deaths during the study period occurred on unpaved surfaces. States varied considerably, ranging from 18% to 79% of their ATV-related roadway deaths occurring on unpaved roads. Paved road crashes were more likely than those on unpaved surfaces to involve males, adolescents and younger adults, passengers, and collisions with other vehicles. Both the pattern of other vehicles involved in collisions and which vehicle hit the other were different for the 2 road types. Alcohol use was higher, helmet use was lower, and head injuries were more likely in paved versus unpaved roadway crashes. However, head injuries still occurred in 76% of fatalities on unpaved roads. Helmets were associated with lower proportions of head injuries among riders, regardless of road surface type. Relative to off-road crashes, both paved and unpaved roads were more likely to involve collisions with another vehicle. The vast majority of roadway crashes, however, did not involve a traffic collision on either paved or unpaved roads

  4. Experimental research on the structural instability mechanism and the effect of multi-echelon support of deep roadways in a kilometre-deep well.

    Directory of Open Access Journals (Sweden)

    Rui Peng

    Full Text Available We study the structural instability mechanism and effect of a multi-echelon support in very-deep roadways. We conduct a scale model test for analysing the structural failure mechanism and the effect of multi-echelon support of roadways under high horizontal stress. Mechanical bearing structures are classified according to their secondary stress distribution and the strength degradation of the surrounding rock after roadway excavation. A new method is proposed by partitioning the mechanical bearing structure of the surrounding rock into weak, key and main coupling bearing stratums. In the surrounding rock, the main bearing stratum is the plastic reshaping and flowing area. The weak bearing stratum is the peeling layer or the caving part. And the key bearing stratum is the shearing and yielding area. The structural fracture mechanism of roadways is considered in analysing the bearing structure instability of the surrounding rock, and multi-echelon support that considers the structural characteristics of roadway bearings is proposed. Results of the experimental study indicate that horizontal pressure seriously influences the stability of the surrounding rock, as indicated by extension of the weak bearing area and the transfer of the main and key bearing zones. The falling roof, rib spalling, and floor heave indicate the decline of the bearing capacity of surrounding rock, thereby causing roadway structural instability. Multi-echelon support is proposed according to the mechanical bearing structure of the surrounding rock without support. The redesigned support can reduce the scope of the weak bearing area and limit the transfer of the main and key bearing areas. Consequently, kilometre-deep roadway disasters, such as wedge roof caving, floor heave, and rib spalling, can be avoided to a certain degree, and plastic flow in the surrounding rock is relieved. The adverse effect of horizontal stress on the vault, spandrel and arch foot decreases. The

    The article analyzes two posters that with the same slogan - "Asylums nevermore" - promote National Anti-Asylum Day. The analysis was based on principles of the symptomatology of social discourse, articulating analytical concepts and practices arising from the French School and the pragmatic dimension of discourse analysis. The results revealed affirmation strategies of the movement for the qualification and exacerbation of the issues of the enunciation and other enunciators, namely political actors of the anti-asylum movement and their allies. It also reveals the attempt to disqualify competitive discourse, especially that which discloses the serious problems of its institutional models, but also by juxtaposing the positive presence of the issuers and enunciators of the posters.

    Objective: To understand the current overall status of implementation on the National Demonstration Areas of Comprehensive Prevention and Control of Non-communicable Diseases. Methods: According to the scheme design of the questionnaires, all the National Demonstration Areas were involved in this study. For each National Demonstration Areas, eight departments were selected to complete a total of 12 questionnaires. Results: Scores related to the implementation of the National Demonstration Areas accounted for 71.8% of the total 170 points. Based on the scores gathered from this study, the 23-items-index-system that represented the status of project implementation was classified into seven categories. Categories with higher percentile scores would include: monitoring (88.0%), safeguard measures (75.0%), health education and health promotion (75.0%). Categories with lower percentile scores would include: the national health lifestyle actions (67.7%), community diagnosis (66.7%), discovery and intervention of high-risk groups (64.7%), and patient management (60.9%). There were significant differences noticed among the eastern, central and western areas on items as safeguard measures, health education/promotion, discovery and intervention of high-risk groups. In all, the implementation programs in the eastern Demonstration Areas seemed better than in the central or western regions. As for the 23 items, five of the highest scores appeared on policy support, mortality surveillance, tumor registration, reporting system on cardiovascular/cerebrovascular events, and on tobacco control, respectively. However, the lowest five scores fell on healthy diet, patient self-management program, oral hygiene, setting up the demonstration units and promotion on basic public health services, respectively. The overall scores in the eastern region was higher than that in the central or the western regions. The scores in the central and western regions showed basically the same. Conclusions

    The combustible volatile matter in coal mine roadway dusts (CVM) has been determined using x-ray backscatter techniques. The correlation between x-ray and chemical techniques is reasonably good for the 92 samples from collieries on the Bulli seam, and the maximum error expected at the maximum level of 11.5 weight per cent CVM permitted in the N.S.W. Coal Mines Regulation Act, 1912, as amended, is about +- 2.5 weight per cent. This x-ray technique can be used only when the combustible volatile content of the coal matter (CVM) varies within a limited range, and a separate calibration is required for each coal seam. Portable equipment based on a radioisotope x-ray source and digital ratemeter makes possible simple and rapid analysis, and with adaptation to use in coal mines should lead to much more comprehensive testing of roadways and hence improved overall prevention of coal dust explosions.

    Incidents involving the exposure of large numbers of people to radiological material can have serious consequences for those affected, their community and wider society. In many instances, the psychological effects of these incidents have the greatest impact. People fear radiation and even incidents which result in little or no actual exposure have the potential to cause widespread anxiety and behavior change. The aim of this study was to assess public intentions, beliefs and information needs in the UK and Germany in response to a hidden radiological exposure device. By assessing how the public is likely to react to such events, strategies for more effective crisis and risk communication can be developed and designed to address any knowledge gaps, misperceptions and behavioral responses that are contrary to public health advice. This study had three stages. The first stage consisted of focus groups which identified perceptions of and reactions to a covert radiological device. The incident was introduced to participants using a series of mock newspaper and broadcast injects to convey the evolving scenario. The outcomes of these focus groups were used to inform national telephone surveys, which quantified intended behaviors and assessed what perceptions were correlated with these behaviors. Focus group and survey results were used to develop video and leaflet communication interventions, which were then evaluated in a second round of focus groups. In the first two stages, misperceptions about the likelihood and routes of exposure were associated with higher levels of worry and greater likelihood of engaging in behaviors that might be detrimental to ongoing public health efforts. The final focus groups demonstrated that both types of misunderstanding are amenable to change following targeted communication. Should terrorists succeed in placing a hidden radiological device in a public location, then health agencies may find that it is easier to communicate effectively

Basically, this research presents the relevant results obtained for the rock burst prevention in the floor of roadway driven along next goaf in the exploitation of thick coal seam with large obliquity in deep well and rock burst tendency. The control mechanism of rock burst in the roadway driven along next goaf is revealed in the present work. That is, the danger of rock burst can be removed by changing the stress environment for the energy accumulation of the floor and by reducing the impact on the roadway floor from the strong dynamic pressure. This result can be profitable being used at the design stage of appropriate position of roadway undergoing rock burst tendency in similar conditions. Based on the analysis regarding the control mechanism, this paper presents a novel approach to the prevention of rock burst in roadway floor under the above conditions. That is, the return airway is placed within the goaf of the upper working face that can prevent the rock burst effectively. And in this way, mining without coal pillar in the thick coal seam with large obliquity and large burial depth (over a thousand meters is realized. Practice also proves that the rock burst in the floor of roadway driven along next goaf is controlled and solved.

    The impact of human activities on biogeochemical cycles in terrestrial environments is nowhere more apparent than in urban landscapes. Trace metals, collected on roadways and transported by storm water, may contaminate soils and sediments associated with storm water management systems. These systems will accumulate metals and associated sediments may reach toxic levels for terrestrial and aquatic organisms using the retention basins as habitat. The fate and bioavailability of these metals once deposited is poorly understood. Here we present results from a dose-response experiment that examines the application of synchrotron X-ray fluorescence methods (μ-SXRF) to test the hypothesis that earthworms will bio-accumulate Zn in a roadway-dust contaminated soil system providing a potential pathway for roadway contaminants into the terrestrial food web, and that the storage and distribution of Zn will change with the level of exposure reflecting the micronutrient status of Zn. Lumbricus friendi was exposed to Zn-bearing roadway dust amended to a field soil at six target concentrations ranging from background levels (45 mg/kg Zn) to highly contaminated levels (460 mg/kg Zn) designed to replicate the observed concentration range in storm-water retention basin soils. After a 30 day exposure, Zn storage in the intestine is positively correlated with dose and there is a change in the pattern of Zn storage within the intestine. This relationship is only clear when μ-SXRF Zn map data is coupled with a traditional toxicological approach, and suggests that the gut concentration in L. friendi is a better indicator of Zn bioaccumulation and storage than the total body burden.

    We measured polycyclic aromatic hydrocarbons (PAHs) in gas and particle phases over two years using high volume samplers equipped with quartz fiber filters and XAD-4 at a rural site, an urban site, and a site adjacent to a heavily trafficked roadway. Overall results were generally as expected, in that concentrations increased from rural to urban to near-roadway sites, and PAHs with high vapor pressures (liquid subcooled, PoL) and low octanol-air partition coefficients (Koa) were mainly in the gas phase, while those with low PoL and high Koa were predominantly in the particle phase. Intermediate PAHs existed in both phases with the phase distribution following a seasonal pattern of higher gas phase concentrations in summer due to temperature effects. The overall pattern of phase distribution was consistent with PAH properties and ambient conditions and was similar at all three sites. The particle-bound fraction (ϕ) was well-described empirically by nonlinear regressions with log Koa and log PoL as predictors. Adsorption and absorption models underestimated the particle-bound fraction for most PAHs. The dual aerosol-air/soot-air model generally represented the gas-particle partitioning better than the other models across all PAHs, but there was a tendency to underestimate the range in the particle-bound fraction seen in measurements. There was a statistically insignificant tendency for higher PAHs in the particle phase at the near roadway site, and one piece of evidence that PAHs may be enriched on ultrafine particles at the near roadway site. Understanding the phase and particle size distributions of PAHs in highly polluted, high exposure microenvironments near traffic sources will help shed light on potential health effects.

    To audit written medical discharge summary procedure and practice against Standard Six (clinical handover) of the Australian National Safety and Quality Health Service Standards at a major regional Victorian health service. Department heads were invited to complete a questionnaire about departmental discharge summary practices. Twenty-seven (82%) department heads completed the questionnaire. Seven (26%) departments had a documented discharge summary procedure. Fourteen (52%) departments monitored discharge summary completion and 13 (48%) departments monitored the timeliness of completion. Seven (26%) departments informed the patient of the content of the discharge summary and six (22%) departments provided the patient with a copy. Seven (26%) departments provided training for staff members on how to complete discharge summaries. Completing discharge summaries was usually delegated to the medical intern. The introduction of the National Service Standards prompted an organisation-wide audit of discharge summary practices against the external criterion. There was substantial variation in the organisation's practices. The Standards and the current audit results highlight an opportunity for the organisation to enhance and standardise discharge summary practices and improve communication with general practice.

  19. A Study on the Fracture Control of Rock Bolts in High Ground Pressure Roadways of Deep Mines

    Full Text Available According to the frequent fractures of rock bolts in high ground pressure roadways of deep mines, this paper analyzes the mechanism of fractures and concludes that high ground pressure and material de-fects are main reasons for the fracture of rock bolts. The basic idea of fracture control of rock bolts in high ground pressure roadways of deep mines is to increase the yield load and the limit load of rock bolt materials and reduce the actual load of rock bolts. There are four ways of controlling rock bolt fracture: increasing the rock bolt diameter, strengthening bolt materials, weakening support rigidity and the implementation of double supporting. With the roadway support of the 2302 working face of a coal mine as the project background, this paper carries out a study on the effect of two schemes, increasing the rock bolt diameter and the double supporting technique through methods of theoretical analysis, numerical simulation and so on. It determines the most reasonable diam-eter of rock bolts and the best delay distance of secondary support. Practices indicate that rock bolt fracture can be effectively controlled through the double supporting technique, which strengthens the roof and two sides through the first supporting technique and strengthens side angles through the secondary supporting technique.

    Full Text Available Artificial explosions are commonly used to prevent rockburst in deep roadways. However, the dissipation of the impact stress wave within the artificial blasting damage zone (ABDZ of the rocks surrounding a deep roadway has not yet been clarified. The surrounding rocks were divided into the elastic zone, blasting damage zone, plastic zone, and anchorage zone in this research. Meanwhile, the ABDZ was divided into the pulverizing area, fractured area, and cracked area from the inside out. Besides, the model of the normal incidence of the impact stress waves in the ABDZ was established; the attenuation coefficient of the amplitude of the impact stress waves was obtained after it passed through the intact rock mass, and ABDZ, to the anchorage zone. In addition, a numerical simulation was used to study the dynamic response of the vertical stress and impact-induced vibration energy in the surrounding rocks. By doing so, the dissipation of the impact stress waves within the ABDZ of the surrounding rocks was revealed. As demonstrated in the field application, the establishment of the ABDZ in the surrounding rocks reduced the effect of the impact-induced vibration energy on the anchorage support system of the roadway.

  1. Improving Pathologists' Communication Skills.

    2016-08-01

    The 2015 Institute of Medicine report on diagnostic error has placed a national spotlight on the importance of improving communication among clinicians and between clinicians and patients [1]. The report emphasizes the critical role that communication plays in patient safety and outlines ways that pathologists can support this process. Despite recognition of communication as an essential element in patient care, pathologists currently undergo limited (if any) formal training in communication skills. To address this gap, we at the University of Washington Medical Center developed communication training with the goal of establishing best practice procedures for effective pathology communication. The course includes lectures, role playing, and simulated clinician-pathologist interactions for training and evaluation of pathology communication performance. Providing communication training can help create reliable communication pathways that anticipate and address potential barriers and errors before they happen. © 2016 American Medical Association.

    Surface waves are commonly used for vibration-based nondestructive testing for infrastructure. Spectral Analysis of Surface Waves (SASW) has been used to detect subsurface properties for geologic inspections. Recently, efforts were made to scale down these subsurface detection approaches to see how they perform on small-scale structures such as concrete slabs and pavements. Additional efforts have been made to replace the traditional surface-mounted transducers with non-contact acoustic transducers. Though some success has been achieved, most of these new approaches are inefficient because they require point-to-point measurements or off-line signal analysis. This article introduces a Mobile Acoustic Subsurface Sensing system as MASS, which is an improved surface wave based implementation for measuring the subsurface profile of roadways. The compact MASS system is a 3-wheeled cart outfitted with an electromagnetic impact source, distance register, non-contact acoustic sensors and data acquisition/ processing equipment. The key advantage of the MASS system is the capability to collect measurements continuously at walking speed in an automatic way. The fast scan and real-time analysis advantages are based upon the non-contact acoustic sensing and fast air-coupled surface wave analysis program. This integration of hardware and software makes the MASS system an efficient mobile prototype for the field test.

    Dynamic wireless charging is a possible cure for the range limitations seen in electric vehicles (EVs) once implemented in highways or city streets. The contribution of this paper is the use of experimental data to show that the expected energy gain from a dynamic wireless power transfer (WPT) system is largely a function of average speed, which allows the power level and number of coils per mile of a dynamic WPT system to be sized for the sustained operation of an EV. First, data from dynamometer testing is used to determine the instantaneous energy requirements of a light-duty EV. Then, experimental data is applied to determine the theoretical energy gained by passing over a coil as a function of velocity and power level. Related simulations are performed to explore possible methods of placing WPT coils within roadways with comparisons to the constant velocity case. Analyses with these cases demonstrate what system ratings are needed to meet the energy requirements of the EV. The simulations are also used to determine onboard energy storage requirements for each driving cycle.

It is well known that post-modernity, described as an era of control, produces only decentralized, imploded subjectivities, who are neither able to question their own being nor to relate one with another in authentic bonds of communication. Today, virtual communication has become an ultimate model of every possible communication whatsoever. The authors, therefore, pose the question of conditions for possibility of subjectivities who would be able and apt for authentic communication, wherein faith, fidelity, truth, and capability of keeping one's word occupy the central place.

    2012-01-01

    Background: The emerging consensus that exposure to near-roadway traffic-related pollution causes asthma has implications for compact urban development policies designed to reduce driving and greenhouse gases. Objectives: We estimated the current burden of childhood asthma-related disease attributable to near-roadway and regional air pollution in Los Angeles County (LAC) and the potential health impact of regional pollution reduction associated with changes in population along major traffic corridors. Methods: The burden of asthma attributable to the dual effects of near-roadway and regional air pollution was estimated, using nitrogen dioxide and ozone as markers of urban combustion-related and secondary oxidant pollution, respectively. We also estimated the impact of alternative scenarios that assumed a 20% reduction in regional pollution in combination with a 3.6% reduction or 3.6% increase in the proportion of the total population living near major roads, a proxy for near-roadway exposure. Results: We estimated that 27,100 cases of childhood asthma (8% of total) in LAC were at least partly attributable to pollution associated with residential location within 75 m of a major road. As a result, a substantial proportion of asthma-related morbidity is a consequence of near-roadway pollution, even if symptoms are triggered by other factors. Benefits resulting from a 20% regional pollution reduction varied markedly depending on the associated change in near-roadway proximity. Conclusions: Our findings suggest that there are large and previously unappreciated public health consequences of air pollution in LAC and probably in other metropolitan areas with dense traffic corridors. To maximize health benefits, compact urban development strategies should be coupled with policies to reduce near-roadway pollution exposure. PMID:23008270

    Passion and sexual satisfaction typically diminish in longer-term relationships, but this decline is not inevitable. We identified the attitudes and behaviors that most strongly differentiated sexually satisfied from dissatisfied men and women who had been together for at least three years (N = 38,747). Data were collected in 2006 from cohabiting and married men (M) and women (W) via an online survey on a major national U.S. news Web site. The vast majority of these participants reported being satisfied with their sex lives during their first six months together (83% W; 83% M). Satisfaction with their current sex lives was more variable, with approximately half of participants reporting overall satisfaction (55% W; 43% M) and the rest feeling neutral (18% W; 16% M) or dissatisfied (27% W; 41% M). More than one in three respondents (38% W; 32% M) claimed their sex lives were as passionate now as in the beginning. Sexual satisfaction and maintenance of passion were higher among people who had sex most frequently, received more oral sex, had more consistent orgasms, and incorporated more variety of sexual acts, mood setting, and sexual communication. We discuss implications of these findings for research and for helping people revitalize their sex lives.

    The present study used the 2013 Health Information National Trends Survey (N = 3185) to examine the effects of patient-centered communication (PCC) and the use of electronic health records (EHRs) on the likelihood of patients receiving a recommended screening for cancer (i.e., mammogram, PSA test). Self-determination theory, a framework of self-initiated extrinsic behaviors, was applied to test mediation models of PCC and EHR use, respectively, through patient activation. The results demonstrated that PCC and EHR use predicted cancer screening (mediated through patient activation), but only for women recommended for biannual mammograms. The aforementioned relationship was not found for men who are recommended for prostate cancer screening. PCC and EHRs do appear to facilitate a patient's ability to take care of their own health, but only under certain circumstances. It was additionally found that men were more likely to report higher degrees of physician PCC when their physicians maintained an EHR, whereas women reported no difference. Future research should examine more nuanced personality factors that affect the perception of PCC in the presence of EHRs and the relationship between men's activation and likelihood of receiving a cancer screen.

    More than 1 million wildlife-vehicle collisions occur annually in the United States. The majority of these accidents involve white-tailed deer (Odocoileus virginianus) and result in >US $4.6 billion in damage and >200 human fatalities. Prior research has used collision locations to assess sitespecific as well as landscape features that contribute to risk of deer-vehicle collisions. As an alternative approach, we calculated road-crossing locations from 25 GPS-instrumented white-tailed deer near Madison, Georgia (n=154,131 hourly locations). We identified crossing locations by creating movement paths between subsequent GPS points and then intersecting the paths with road locations. Using AIC model selection, we determined whether 10 local and landscape variables were successful at identifying areas where higher frequencies of deer crossings were likely to occur. Our findings indicate that traffic volume, distance to riparian areas, and the amount of forested area influenced the frequency of road crossings. Roadways that were predominately located in wooded landscapes and 200–300 m from riparian areas were crossed frequently. Additionally, we found that areas of low traffic volume (e.g., county roads) had the highest frequencies of deer crossings. Analyses utilizing only records of deer-vehicle collision locations cannot separate the relative contribution of deer crossing rates and traffic volume. Increased frequency of road crossings by deer in low-traffic, forested areas may lead to a greater risk of deer-vehicle collision than suggested by evaluations of deer-vehicle collision frequency alone.

Some of its results will allow for increasing the availability of the machinery through the decrease of both programmed maintenance time and medium time to repair. Other results are related to the adoption of new types (in coal mining) of support considered promising from a productivity increase perspective, such as concrete spraying. Research topics addressed in the project could be classified roughly in two groups: horizontal (underlying common technologies) and vertical (related to the actual implementation of devices, software and systems). Among the results for horizontal activities, those that deserve special mention are the development of an Atex 3D laser scanner, Atex WLAN (WiFi) access points, cameras and PDA, as well as methods for storing and representing in 3D machinery components, subassemblies and complete machines. Amid results of vertical activities is the implementation of a central maintenance control mining machinery is concentrated. Engineers in charge of CMCR have online access to all machinery-related information, including direct access to manufacturers' databases. Images, voice and data flowing from the underground, and diagrams and advice flowing from the surface are transmitted and displayed using the technologies developed during horizontal activities. Other important results are the development of methods for assessing the quality of execution of roadway support when using sprayed concrete for this purpose, also using technologies (such as laser scanning) developed within the horizontal activities. 10 refs., 162 figs., 7 tabs.

    There are more than 4 million miles of roads and 600,000 bridges in the United States alone. On-going investments are required to maintain the physical and operational quality of these assets to ensure public's safety and prosperity of the economy. Planning efficient maintenance and repair (M&R) operations must be armed with a meticulous pavement inspection method that is non-disruptive, is affordable and requires minimum manual effort. The Versatile Onboard Traffic Embedded Roaming Sensors (VOTERS) project developed a technology able to cost- effectively monitor the condition of roadway systems to plan for the right repairs, in the right place, at the right time. VOTERS technology consists of an affordable, lightweight package of multi-modal sensor systems including acoustic, optical, electromagnetic, and GPS sensors. Vehicles outfitted with this technology would be capable of collecting information on a variety of pavement-related characteristics at both surface and subsurface levels as they are driven. By correlating the sensors' outputs with the positioning data collected in tight time synchronization, a GIS-based control center attaches a spatial component to all the sensors' measurements and delivers multiple ratings of the pavement every meter. These spatially indexed ratings are then leveraged by VOTERS decision making modules to plan the optimum M&R operations and predict the future budget needs. In 2014, VOTERS inspection results were validated by comparing them to the outputs of recent professionally done condition surveys of a local engineering firm for 300 miles of Massachusetts roads. Success of the VOTERS project portrays rapid, intelligent, and comprehensive evaluation of tomorrow's transportation infrastructure to increase public's safety, vitalize the economy, and deter catastrophic failures.

    To compare perceptions about rural road and general driving behaviors between teens who live in- and out-of-town from rural communities in Iowa. A cross-sectional survey was conducted with 160 teens anticipating their Intermediate License within 3 months upon enrollment into this study. Self-administered surveys were used to collect demographics and driving exposures (eg, frequency of driving, age when first drove unsupervised). Two Likert scales were included to measure agreement with safe driving behaviors on rural roads and general safe driving behaviors (eg, speeding, seat belt use). T-tests were calculated comparing mean composite scores between in- and out-of-town teens, and between mean rural road and general driving safety attitude scores. A linear regression multivariable model was constructed to identify predictors of the rural road score. While the majority of teens endorsed rural road and general safe driving behaviors, up to 40% did not. Thirty-two percent did not believe the dangers of animals on rural roads, and 40% disagreed that exceeding the speed limit is dangerous. In-town teens were less safety conscious about rural road hazards with a significantly lower mean composite score (4.4) than out-of-town teens (4.6); mean scores for general driving behaviors were similar. Living out-of-town and owning one's own car were significant predictors of increased rural road safety scores. Rural, in-town teens have poorer safety attitudes about rural roadway hazards compared with out-of-town teens. Interventions that involve education, parental supervision, and practice on rural roads are critical for preventing teen crashes on rural roads. No claim to original US government works.

  18. Effect of Stresses and Strains of Roadway Surrounding Rocks on Borehole Airtightness

    Directory of Open Access Journals (Sweden)

    WU Wei

    2016-02-01

    Full Text Available At present, many high gas and outburst mines have poor gas drainage effects. An important reason influencing the gas drainage effect is a poor hole-sealing effect. Most studies on gas drainage borehole sealing focus on local and foreign borehole sealing methods, borehole sealing equipment, and borehole sealing materials. Numerical simulations of initial drilling sealing depth are insufficient because studies on this subject are few. However, when the initial sealing depth of the borehole is not chosen reasonably, air can enter the gas drainage drill hole through the circumferential crack of roadway surrounding rocks under the influence of suction pressure of the drainage system. This phenomenon ultimately affects the hole-sealing effect. To improve the drilling hole sealing of gas drainage boring, we deduced the expression formulas of the crushing zone, plastic zone, and elastic zone around the coal-seam floor stone drift and conducted a stress–strain analysis of the coal-seam floor stone drift of the 2145 working surfaces of the Sixth Coal Mine of Hebi Coal Mine Group Company by using theoretical analysis, numerical simulation, and on-scene verification. Finally, we obtain the initial drilling sealing depth, which is a main contribution of this study. The results prove the following. The performed hole-sealing process with an initial drilling sealing depth of 8 m has a gas drainage efficiency of 55%. Compared with the previous 6.8 m initial drilling sealing depth with a gas drainage efficiency of less than 30%, which was adopted by the mine, the initial sealing depth of 8 m chosen in the numerical simulation is reasonable and conforms to the actual situation on the spot. Therefore, the initial drilling sealing depth chosen in the numerical simulation will produce practical and effective guidance to study the field hole-sealing depth.

  19. Testing Re-entrained Aerosol Kinetic Emissions from Roads : a new approach to infer silt loading on roadways

    Science.gov (United States)

    Kuhns, H.; Etyemezian, V.; Landwehr, D.; MacDougall, C.; Pitchford, M.; Green, M.

    PM 10 and PM 2.5 emissions from roadways are currently estimated using the silt loading on the road surface as a surrogate for the emissions potential of road dust. While the United States Environmental Protection Agency prescribes this method in AP-42, there is considerable cost associated with silt loading measurements; it is feasible to sample only a small portion of a roadway network. A new approach for measuring the concentration of suspendable PM 10 above road surfaces has been developed to obtain a more spatially representative estimate of a road's potential to emit dust. The Testing Re-entrained Aerosols Kinetic Emissions from Roads (TRAKER) system uses real-time aerosol sensors mounted on a vehicle to measure the concentration of dust suspended from the road while the vehicle is in motion. When coupled with a Global Positioning System (GPS) instrument, TRAKER can be used to efficiently survey the changes in suspendable particles due to varying road conditions over a large spatial domain. In a recent study on paved roads in Las Vegas, the TRAKER system was compared with collocated silt loading measurements. The TRAKER system was also used to survey the relative amounts of suspendable road dust on approximately 300 miles of paved roads. The system provides a unique perspective on road dust sources and their spatial distribution. Results of this study indicated that the difference of the PM 10 concentrations measured behind the tire and on the hood is exponentially related to vehicle speed. This was an interesting finding because current AP-42 road dust emissions estimation methods do not include vehicle speed as a factor in the emissions calculations. The experiment also demonstrated that the distribution of suspendable material on roadways is highly variable and that a large number of samples are needed to represent road dust emissions potential on an urban scale for a variety of road and activity conditions.

    The research described in this paper explored the factors contributing to the injury severity resulting from the motorcycle at-fault accidents in rural and urban areas in Alabama. Given the occurrence of a motorcycle at-fault crash, random parameter logit models of injury severity (with possible outcomes of fatal, major, minor, and possible or no injury) were estimated. The estimated models identified a variety of statistically significant factors influencing the injury severities resulting from motorcycle at-fault crashes. According to these models, some variables were found to be significant only in one model (rural or urban) but not in the other one. For example, variables such as clear weather, young motorcyclists, and roadway without light were found significant only in the rural model. On the other hand, variables such as older female motorcyclists, horizontal curve and at intersection were found significant only in the urban model. In addition, some variables (such as, motorcyclists under influence of alcohol, non-usage of helmet, high speed roadways, etc.) were found significant in both models. Also, estimation findings showed that two parameters (clear weather and roadway without light) in the rural model and one parameter (on weekend) in the urban model could be modeled as random parameters indicating their varying influences on the injury severity due to unobserved effects. Based on the results obtained, this paper discusses the effects of different variables on injury severities resulting from rural and urban motorcycle at-fault crashes and their possible explanations.

    2011-01-01

    This work shows a non-invasive method for micro-deformation measurements on concrete structures using Bragg grating sensors in optical fibers adhered to the surface. We present the measurements on roadway slabs under a load of 10 kN, and we find an approximated ratio of 2:1 between the deformation registered by the sensors and the values from a computational simulation with the finite element method. We propose the use of these sensors for structural monitoring of the slabs and this installation shape for avoiding bends that can damage the edges in the optical fiber in embebed sensors in vertical shape.

  3. A microcomputer-based model for identifying urban and suburban roadways with critical large truck accident rates

    Brogan, J.D.; Cashwell, J.W.

    1992-01-01

    This paper presents an overview of techniques for merging highway accident record and roadway inventory files and employing the combined data set to identify spots or sections on highway facilities in urban and suburban areas with unusually high large truck accident rates. A statistical technique, the rate/quality control method, is used to calculate a critical rate for each location of interest. This critical rate may then be compared to the location's actual accident rate to identify locations for further study. Model enhancements and modifications are described to enable the technique to be employed in the evaluation of routing alternatives for the transport of radioactive material

    To determine communication strategies associated with smoking cessation in the National Health Service community pharmacy Stop Smoking programme. 11 community pharmacies in three inner east London boroughs. 9 stop smoking advisers and 16 pairs of smokers who either quit or did not quit at 4 weeks, matched on gender, ethnicity, age and smoking intensity. 1-3 audio-recorded consultations between an adviser and each pair member over 5-6 weeks were analysed using a mixed-method approach. First a content analysis was based on deductive coding drawn from a theme-oriented discourse analysis approach and the Roter Interaction Analysis System. Core themes were identified through this quantification to explore in detail the qualitative differences and similarities between quitters and non-quitters. Quantitative analysis revealed advisers used a core set of counselling strategies that privileged the 'voice of medicine' and often omitted explicit motivational interviewing. Smokers tended to quit when these core strategies were augmented by supportive talk, clear permission for smokers to seek additional support from the adviser between consultations, encouragement for smokers to use willpower. The thematic analysis highlighted the choices made by advisers as to which strategies to adopt and the impacts on smokers. The first theme 'Negotiating the smoker-adviser relationship' referred to adviser judgements about the likelihood the smoker would quit. The second theme, 'Roles of the adviser and smoker in the quit attempt', focused on advisers' counselling strategies, while the third theme, 'Smoker and adviser misalignment on reasons for smoking, relapsing and quitting', concerned inconsistencies in the implementation of National Centre for Smoking Cessation and Training recommendations. Advisers in community pharmacies should use the advantages of their familiarity with smokers to ensure appropriate delivery of patient-centred counselling strategies and reflect on the impact on

    Given the worldwide proliferation of cellphones, this paper examines their potential use for the surveillance of non-communicable disease (NCD) risk factors in a Middle Eastern country. Data were derived from a national household survey of 2,656 adults (aged 18 years or older) in Lebanon in 2009. Responses to questions on phone ownership yielded two subsamples, the 'cell phone sample' (n = 1,404) and the 'any phone sample' (n = 2,158). Prevalence estimates of various socio-demographics and 11 key NCD risk factors and comorbidities were compared between each subsample and the overall household sample. Adjusting for baseline age and sex distribution, no differences were observed for all NCD indicators when comparing either of subsamples to the overall household sample, except for binge drinking [(OR = 1.55, 95 % CI: 1.33-1.81) and (OR = 1.48, 95 % CI: 1.18-1.85) for 'cell phone subsample' and 'any phone subsample', respectively] and self-rated health (OR = 1.23, 95 % CI: 1.10-1.36) and (OR = 1.16, 95 % CI: 1.02-1.32), respectively). Differences in the odds of hyperlipidemia (OR = 1.27, 95 % CI: 1.06-1.51) was also found in the subsample of 'any phone' carriers. Multi-mode telephone surveillance techniques provide viable alternative to face-to-face surveys in developing countries. Cell phones may also be useful for personalized public health and medical care interventions in young populations.

    This document is the final report of a two-year development, test, and demonstration project, 'Cohesive Application of Standards- Based Connected Devices to Enable Clean Energy Technologies.' The project was part of the National Renewable Energy Laboratory's (NREL's) Integrated Network Testbed for Energy Grid Research and Technology (INTEGRATE) initiative hosted at Energy Systems Integration Facility (ESIF). This project demonstrated techniques to control distribution grid events using the coordination of traditional distribution grid devices and high-penetration renewable resources and demand response. Using standard communication protocols and semantic standards, the project examined the use cases of high/low distribution voltage, requests for volt-ampere-reactive (VAR) power support, and transactive energy strategies using Volttron. Open source software, written by EPRI to control distributed energy resources (DER) and demand response (DR), was used by an advanced distribution management system (ADMS) to abstract the resources reporting to a collection of capabilities rather than needing to know specific resource types. This architecture allows for scaling both horizontally and vertically. Several new technologies were developed and tested. Messages from the ADMS based on the common information model (CIM) were developed to control the DER and DR management systems. The OpenADR standard was used to help manage grid events by turning loads off and on. Volttron technology was used to simulate a homeowner choosing the price at which to enter the demand response market. Finally, the ADMS used newly developed algorithms to coordinate these resources with a capacitor bank and voltage regulator to respond to grid events.

    validity strategy a flexible fuzzy structure has been developed with the option of switching off several sensors while still using the same fuzzy block. The environmental observation leads to detection probabilities of ice, snow and water on the road. From the gathered information of the environmental observation, the slippery road detection and the ABS and ESP control operating, it is possible to output information about the actual friction value. Information about roadways with a high vertical excitation as well as road slope have to be detected and considered. The environmental block is able to detect most typical road state situations due to partly redundant, partly complementary sensor information. (orig.) (orig.)

    Understanding the organic matter/organic carbon (OM/OC) ratio in ambient particulate matter (PM) is critical to achieve mass closure in routine PM measurements, to assess the sources of and the degree of chemical processing organic aerosol particles have undergone, and to relate ambient pollutant concentrations to health effects. Of particular interest is how the OM/OC ratio varies in the urban environment, where strong spatial and temporal gradients in source emissions are common. We provide results of near-roadway high-time-resolution PM1 OM concentration and OM/OC ratio observations during January 2008 at Fyfe Elementary School in Las Vegas, NV, 18 m from the U.S. 95 freeway soundwall, measured with an Aerodyne high-resolution time-of-flight aerosol mass spectrometer (HR-AMS). The average OM/OC ratio was 1.54 (+/- 0.20 standard deviation), typical of environments with a low amount of secondary aerosol formation. The 2-min average OM/OC ratios varied between 1.17 and 2.67, and daily average OM/OC ratios varied between 1.44 and 1.73. The ratios were highest during periods of low OM concentrations and generally low during periods of high OM concentrations. OM/OC ratios were low (1.52 +/- 0.14, on average) during the morning rush hour (average OM = 2.4 microg/m3), when vehicular emissions dominate this near-road measurement site. The ratios were slightly lower (1.46 +/- 0.10) in the evening (average OM = 6.3 microg/m3), when a combination of vehicular and fresh residential biomass burning emissions was typically present during times with temperature inversions. The hourly averaged OM/OC ratio peaked at 1.66 at midday. OM concentrations were similar regardless of whether the monitoring site was downwind or upwind of the adjacent freeway throughout the day, though they were higher during stagnant conditions (wind speed < 0.5 m/sec). The OM/OC ratio generally varied more with time of day than with wind direction and speed.

    Full Text Available There is high demand for roadway support in coal mines for the swelling soft rocks. As high strength steel sets can be taken as an effective alternative to control large deformation in this type of rocks, based on an original set, three new sets, including a floor beam set, a roof and floor beams set, and a roof and floor beams and braces set, are proposed in this research. In order to examine the strengths of new sets, four scaled sets of one original set, and three new sets, have been manufactured and tested in loading experiments. Results indicated that three new sets all exhibited higher strength than the original set. In experiments, the roof beam in set plays a significant effect on top arch strengthening, while the floor beam plays significant effect on bottom arch strengthening. The maximum bearing capacity and stiffness of the top arch with roof beam are increased to 1.63 times and 3.06 times of those in the original set, and the maximum bearing capacity and stiffness of the bottom arch with floor beam are increased to 1.44 times and 3.55 times of those in original set. Based on the roof and floor beams, two more braces in the bottom arch also play a significant effect in bottom corners strengthening, but extra braces play little role in top arch strengthening. These new sets provide more choices for roadway support in swelling soft rocks.

    A recent review article emphasized the need for further characterizations of the carbonaceous fraction of mobile source emissions, particularly with the impending removal of lead alkyl octane boosters and bromine-containing lead scavengers from regular leaded gasolines. The lead and bromine emitted from the combustion of these fuels have been used as tracers of mobile source emissions for a number of years. Single vehicle emission studies have shed light on the relationship between engine operating parameters and the chemical characteristics of the emissions but they are not suitable for use in source apportionment studies which require emission data from a large number of different vehicles. Air particulate samples collected near a busy highway or in a roadway tunnel would be more appropriate for use in estimating the mobile source contribution of organic compounds to a region. Suspended particle samples collected in a heavily-travelled roadway tunnel (Baltimore Harbor Tunnel, Baltimore, Maryland) were characterized for polycyclic aromatic hydrocarbons (PAH) and some nitro-PAH by gas and liquid chromatographic techniques. These samples included those collected on Teflon filters and on glass fiber filters for investigating any differences in samples collected on an inert (Teflon) and more reactive (glass-fiber) medium. All samples collected on Teflon were backed-up with polyurethane foam plugs (PUF) which trapped any inherent vapor-phase PAH as well as any compounds ''blown-off'' the particles during collection

    Full Text Available Cardiovascular disease (CVD, including heart failure, is a major cause of morbidity and mortality, particularly among African Americans. Exposure to ambient air pollution, such as that produced by vehicular traffic, is believed to be associated with heart failure, possibly by impairing cardiac function. We evaluated the cross-sectional association between residential proximity to major roads, a marker of long-term exposure to traffic-related pollution, and echocardiographic indicators of left and pulmonary vascular function in African Americans enrolled in the Jackson Heart Study (JHS: left ventricular ejection fraction, E-wave velocity, isovolumic relaxation time, left atrial diameter index, and pulmonary artery systolic pressure. We examined these associations using multivariable linear or logistic regression, adjusting for potential confounders. Of 4866 participants at study enrollment, 106 lived <150 m, 159 lived 150–299 m, 1161 lived 300–999 m, and 3440 lived ≥1000 m from a major roadway. We did not observe any associations between residential distance to major roads and these markers of cardiac function. Results were similar with additional adjustment for diabetes and hypertension, when considering varying definitions of major roadways, or when limiting analyses to those free from cardiovascular disease at baseline. Overall, we observed little evidence that residential proximity to major roads was associated with cardiac function among African Americans.

    Unhealthy diets are heavily driven by unhealthy food environments. The International Network for Food and Obesity/non-communicable diseases (NCDs) Research, Monitoring and Action Support (INFORMAS) has been established to reduce obesity, NCDs and their related inequalities globally. This paper describes the design and methods of the first-ever, comprehensive national survey on the healthiness of food environments and the public and private sector policies influencing them, as a first step towards global monitoring of food environments and policies. A package of 11 substudies has been identified: (1) food composition, labelling and promotion on food packages; (2) food prices, shelf space and placement of foods in different outlets (mainly supermarkets); (3) food provision in schools/early childhood education (ECE) services and outdoor food promotion around schools/ECE services; (4) density of and proximity to food outlets in communities; food promotion to children via (5) television, (6) magazines, (7) sport club sponsorships, and (8) internet and social media; (9) analysis of the impact of trade and investment agreements on food environments; (10) government policies and actions; and (11) private sector actions and practices. For the substudies on food prices, provision, promotion and retail, 'environmental equity' indicators have been developed to check progress towards reducing diet-related health inequalities. Indicators for these modules will be assessed by tertiles of area deprivation index or school deciles. International 'best practice benchmarks' will be identified, against which to compare progress of countries on improving the healthiness of their food environments and policies. This research is highly original due to the very 'upstream' approach being taken and its direct policy relevance. The detailed protocols will be offered to and adapted for countries of varying size and income in order to establish INFORMAS globally as a new monitoring initiative

    Objective: To understand the current situation on management of diabetes mellitus patients aged 35 and above in the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases, in China. Methods: Local residents, aged 18 years and above were randomly selected by a complex, multistage, probability sampling method. Face-to-face questionnaire survey was carried out between November and December 2016. Rates regarding prevalence, treatment and management of diabetes were calculated, and influencing factors of diabetes were analyzed by using the non-conditional logistic regression model. Results: A total of 3 213 residents aged ≥35 years were included in this study, of which 11.48% (369/3 213) reported that they had ever been informed by a doctor or other health worker that their blood sugar level was high or being diabetic. The rate of self-reported treatment among the diabetic patients was 83.20% (307/369). Rates on overall management and standardized management were 69.92% (258/369) and 53.66% (198/369), respectively. Higher rates were seen in residents aged 55 to 64 years, 76.32% for overall management and 59.65% for standardized management. Through multiple logistic regression analysis, we found that standardized management for diabetes was much higher in the Demonstration Areas located in the eastern areas ( OR =2.942, 95% CI : 1.547-5.594), or patients with characteristics including high implementation score ( OR =3.499, 95% CI : 1.865-6.563), already signed family doctors ( OR =5.661, 95% CI : 3.237-9.899), or without hypertension ( OR =1.717, 95% CI : 1.010- 2.920). Residents who were living in the first and second batch areas of implementation or responding to the NCDs with positive attitude were more likely to accept standardized management. Conclusion: Prevention and management programs on diabetes had met the requirements set for the Demonstration Areas which had promoted the specific implementation and further

    Commuters who spend long hours on roads are exposed to high levels of traffic related air pollutants (TRAPs). Despite some well-known multiple adverse effects of TRAPs on human health, limited studies have focused on mitigation strategies to reduce these effects. In this study, we measured fine particulate matter (PM2.5) and ultrafine particle (UFP) concentrations inside and outside 17 taxis simultaneously while they were driven on roadways. The drivers' urinary monohydroxylated polycyclic aromatic hydrocarbons (OH-PAHs) and malondialdehyde (MDA) concentrations just before and right after the driving tests were also determined. Data were collected under three driving conditions (i.e. no mitigation (NM), window closed (WC), and window closed plus using high efficiency cabin air filters (WC+HECA)) for each taxi and driver. The results show that, compared to NM, the WC+HECA reduced in-cabin PM2.5 and UFP concentrations, by 37% and 47% respectively (p health.

    Full Text Available The influence of traffic-related air pollution on indoor residential exposure is not well characterized in homes with high natural ventilation in low-income countries. Additionally, domestic allergen exposure is unknown in such populations. We conducted a pilot study of 25 homes in peri-urban Lima, Peru to estimate the effects of roadway proximity and season on residential concentrations. Indoor and outdoor concentrations of particulate matter (PM2.5, nitrogen dioxide (NO2, and black carbon (BC were measured OPEN ACCESS Int. J. Environ. Res. Public Health 2015, 12 13467 during two seasons, and allergens were measured in bedroom dust. Allergen levels were highest for dust mite and mouse allergens, with concentrations above clinically relevant thresholds in over a quarter and half of all homes, respectively. Mean indoor and outdoor pollutant concentrations were similar (PM2.5: 20.0 vs. 16.9 μg/m3, BC: 7.6 vs. 8.1 μg/m3, NO2: 7.3 vs. 7.5 ppb, and tended to be higher in the summer compared to the winter. Road proximity was significantly correlated with overall concentrations of outdoor PM2.5 (rs = −0.42, p = 0.01 and NO2 (rs = −0.36, p = 0.03, and outdoor BC concentrations in the winter (rs = −0.51, p = 0.03. Our results suggest that outdoor-sourced pollutants significantly influence indoor air quality in peri-urban Peruvian communities, and homes closer to roadways are particularly vulnerable.

  10. Carbon monoxide levels measured in major commuting corridors covering different landuse and roadway microenvironments in Hong Kong

    Science.gov (United States)

    Chan, L. Y.; Liu, Y. M.; Lee, S. C.; Chan, C. Y.

    Vehicle exhaust is the major source of pollutant in modern cities. About half of Hong Kong residents are living in suburban or rural areas. They need to traverse through tunnels, highways, urban street canyons and other road conditions in different landuse areas when they traverse to work in urban centres or new towns. Also, there is increasing traffic, especially trucks across the border between Hong Kong and mainland China via several border highways. This study helps us in assessing the exposure level of suburban and cross border commuters. Carbon monoxide (CO) is used as a tracer for traffic emission. An experimental vehicle traversing major commuting corridors were used to measure CO levels in different landuse and roadway microenvironments including tunnels and highways. The air samples were taken simultaneously at the outside and inside of a travelling vehicle. Result indicates that the pattern of fluctuation of the out-vehicle and in-vehicle CO level vary with different landuse areas. The variation pattern of in-vehicle CO level is closely related to that of out-vehicle level. The effects of the out-vehicle CO concentration on the in-vehicle CO concentration under different roadway conditions in various landuse categories are examined. There is an indication that external air pollutants penetrated into the in-vehicle compartment through car body cracks, ventilation system. From our observation, the exhaust of a nearby petrol vehicle contributed significantly to the in-vehicle CO level. The use of low standard of diesel fuel from Shenzhen in mainland China leads to higher CO level near border area.

    2014-01-01

    Background Emerging evidence suggests that near-roadway air pollution (NRP) exposure causes childhood asthma. Associated costs are not well documented. Objective We estimated the cost of childhood asthma attributable to residential NRP exposure and regional ozone (O3) and nitrogen dioxide (NO2) in Los Angeles County. We developed a novel approach to apportion the costs between these exposures under different pollution scenarios. Methods We integrated results from a study of willingness to pay to reduce the burden of asthma with studies of health care utilization and charges to estimate the costs of an asthma case and exacerbation. We applied those costs to the number of asthma cases and exacerbations due to regional pollution in 2007 and to hypothetical scenarios of a 20% reduction in regional pollution in combination with a 20% reduction or increase in the proportion of the total population living within 75m of a major roadway. Results Cost of air pollution-related asthma in Los Angeles County in 2007 was $441 million for O3 and $202 million for NO2 in 2010 dollars. Cost of routine care (care in absence of exacerbation) accounted for 18% of the combined NRP and O3 cost and 39% of the combined NRP and NO2 cost—costs not recognized in previous analyses. NRP-attributable asthma accounted for 43% (O3) to 51% (NO2) of the total annual cost of exacerbations and routine care associated with pollution. Hypothetical scenarios showed that costs from increased NRP exposure may offset savings from reduced regional pollution. Conclusions Our model disaggregates the costs of regional pollution and NRP exposure and illustrates how they might vary under alternative exposure scenarios. The cost of air pollution is a substantial burden on families and an economic loss for society. PMID:25439228

  12. A simple semi-empirical technique for apportioning the impact of roadways on air quality in an urban neighbourhood

    Air pollution from the transport sector has a marked effect on human health, so isolating the pollutant contribution from a roadway is important in understanding its impact on the local neighbourhood. This paper proposes a novel technique based on a semi-empirical air pollution model to quantify the impact from a roadway on the air quality of a local neighbourhood using ambient records of a single air pollution monitor. We demonstrate the proposed technique using a case study, in which we quantify the contribution from a major highway with respect to the local background concentration in Auckland, New Zealand. Comparing the diurnal variation of the model-separated background contribution with real measurements from a site upwind of the highway shows that the model estimates are reliable. Amongst all of the pollutants considered, the best estimations of the background were achieved for nitrogen oxides. Although the multi-pronged approach worked well for predominantly vehicle-related pollutants, it could not be used effectively to isolate emissions of PM10 due to the complex and less predictable influence of natural sources (such as marine aerosols). The proposed approach is useful in situations where ambient records from an upwind background station are not available (as required by other techniques) and is potentially transferable to situations such as intersections and arterial roads. Applying this technique to longer time series could help to understand the changes in pollutant concentrations from the road and background sources for different emission scenarios, for different years or seasons. Modelling results also show the potential of such a hybrid semi-empirical models to contribute to our understanding of the physical parameters determining air quality and to validate emissions inventory data.

Our interest is to demonstrate the differences between countries under the aspects of national constitution and governmental institutions that provide or not provide guidelines in terms of the use and protection of communication national organizations that provide additional guidelines international organizations for the use of mass communication media in a country. The interplay of national constitution, legislative, and governmental institutions is the framework for the existence of national mass communication. Under the title “Waves in The Communication Flow“we will face the framework of exterior institutions of different national states regarding their influence on mass communication. As mass communication we can define all institutions producing information for a wide audience delivered in mass media. As a process we can define mass communication as a ‘flow of any information’ delivered by mass media. This flow can be promoted or prohibited by the framework of institutions named above. This article examines the extent and nature of the use of laws and constitutional systems with an interest in the methodology of comparative studies in constitutional law.

    In 1994, the Clinton Administration issued a report, 'Science in the National Interest', which identified new national science goals. Two of the five goals are related to science communications: produce the finest scientists and engineers for the 21st century, and raise scientific and technological literacy of all Americans. In addition to the guidance and goals set forth by the Administration, NASA has been mandated by Congress under the 1958 Space Act to 'provide for the widest practicable and appropriate dissemination concerning its activities and the results thereof'. In addition to addressing eight Goals and Plans which resulted from a January 1994 meeting between NASA and members of the broader scientific, education, and communications community on the Public Communication of NASA's Science, the Science Communications Working Group (SCWG) took a comprehensive look at the way the Agency communicates its science to ensure that any changes the Agency made were long-term improvements. The SCWG developed a Science Communications Strategy for NASA and a plan to implement the Strategy. This report outlines a strategy from which effective science communications programs can be developed and implemented across the agency. Guiding principles and strategic themes for the strategy are provided, with numerous recommendations for improvement discussed within the respective themes of leadership, coordination, integration, participation, leveraging, and evaluation.

    We examined associations of residential distance to major roadways, as a proxy for traffic-related air pollution exposures, with sperm characteristics and male reproductive hormones. The cohort included 797 men recruited from Massachusetts General Hospital Fertility Center between 2000 and 2015 to participate in fertility research studies. Men reported their residential addresses at enrollment and provided 1-6 semen samples and a blood sample during follow-up. We estimated the Euclidean distance to major roadways (e.g. interstates and highways: limited access highways, multi-lane highways (not limited access), other numbered routes, and major roads) using information from the Massachusetts Department of Geographic Information Systems. Semen parameters (1238 semen samples), sperm DNA integrity (389 semen samples), chromosomal disomy (101 semen samples), and serum reproductive hormones (405 serum samples) were assessed following standard procedures. Men in this cohort were primarily Caucasian (86%), not current smokers (92%), with a college or higher education (88%), and had an average age of 36 years and BMI of 27.7 kg/m 2 . The median (interquartile range) residential distance to a major roadway was 111 (37, 248) meters. Residential proximity to major roadways was not associated with semen parameters, sperm DNA integrity, chromosomal disomy, or serum reproductive hormone concentrations. The adjusted percent change (95% CI) in semen quality parameters associated with a 500 m increase in residential distance to a major roadway was -1.0% (-6.3, 4.5) for semen volume, 4.3% (-5.8, 15.7) for sperm concentration, 3.1% (-7.2, 14.5) for sperm count, 1.1% (-1.2, 3.4) for % total motile sperm, and 0.1% (-0.3, 0.5) for % morphologically normal sperm. Results were consistent when we modeled the semen parameters dichotomized according to WHO 2010 reference values.

    DeGroot, R. M.; Long, K.; Strauss, J. A.

    2017-12-01

    The United States Geological Survey (USGS) and its partners are developing the ShakeAlert Earthquake Early Warning System for the West Coast of the United States. To be an integral part of successful implementation, ShakeAlert engagement programs and materials must integrate with and leverage broader earthquake risk programs. New methods and products for dissemination must be multidisciplinary, cost effective, and consistent with existing hazards education and communication efforts. The ShakeAlert Joint Committee for Communication, Education, and Outreach (JCCEO), is identifying, developing, and cultivating partnerships with ShakeAlert stakeholders including Federal, State, academic partners, private companies, policy makers, and local organizations. Efforts include developing materials, methods for delivery, and reaching stakeholders with information on ShakeAlert, earthquake preparedness, and emergency protective actions. It is essential to develop standards to ensure information communicated via the alerts is consistent across the public and private sector and achieving a common understanding of what actions users take when they receive a ShakeAlert warning. In February 2017, the JCCEO convened the Warning Message Focus Group (WMFG) to provide findings and recommendations to the Alliance for Telecommunications Industry Solutions on the use of earthquake early warning message content standards for public alerts via cell phones. The WMFG represents communications, education, and outreach stakeholders from various sectors including ShakeAlert regional coordinators, industry, emergency managers, and subject matter experts from the social sciences. The group knowledge was combined with an in-depth literature review to ensure that all groups who could receive the message would be taken into account. The USGS and the participating states and agencies acknowledge that the implementation of ShakeAlert is a collective effort requiring the participation of hundreds of

    The purpose of this paper is to recommend regulatory guidance for reviewers examining computer communication systems used in nuclear power plants. The recommendations cover three areas important to these communications systems: system design, communication protocols, and communication media. The first area, system design, considers three aspects of system design--questions about architecture, specific risky design elements or omissions to look for in designs being reviewed, and recommendations for multiplexed data communication systems used in safety systems. The second area reviews pertinent aspects of communication protocol design and makes recommendations for newly designed protocols or the selection of existing protocols for safety system, information display, and non-safety control system use. The third area covers communication media selection, which differs significantly from traditional wire and cable. The recommendations for communication media extend or enhance the concerns of published IEEE standards about three subjects: data rate, imported hazards and maintainability

    Full Text Available Use of stone column technique to improve soft foundation soils under roadway embankments has proven to increase the bearing capacity and reduce the potential settlement. The potential contribution of stone columns to the stability of roadway embankments against general (i.e. deep-seated failure needs to be thoroughly investigated. Therefore, a two-dimensional finite difference model implemented by FLAC/SLOPE 7.0 software, was employed in this study to assess the stability of a roadway embankment fill built on a soft soil deposit improved by stone column technique. The stability factor of safety was obtained numerically under both short-term and long-term conditions with the presence of water table. Two methods were adopted to convert the three-dimensional model into plane strain condition: column wall and equivalent improved ground methods. The effect of various parameters was studied to evaluate their influence on the factor of safety against embankment instability. For instance, the column diameter, columns’ spacing, soft soil properties for short-term and long-term conditions, and the height and friction angle of the embankment fill. The results of this study are developed in several design charts.
