Patients may bring unreliable information to the physician, complicating the physician–patient relationship, or outside information seeking may complement physician information provision, reinforcing patients’ responsibility for their health. The current descriptive evidence base is weak and focuses primarily on the Internet's effects on physician–patient relations. This study describes how cancer patients bring information to their physicians from a range of sources and are referred by physicians to these sources; the study also examines explanations for these behaviors. Patients with breast, prostate, and colon cancer diagnosed in 2005 (N = 1,594) were randomly drawn from the Pennsylvania Cancer Registry; participants returned mail surveys in Fall 2006 (response rate = 64%). There is evidence that both bringing information to physicians and being referred to other sources reflects patients’ engagement with health information, preference for control in medical decision making, and seeking and scanning for cancer-related information. There is also evidence that patients who bring information from a source are referred back to that source. PMID:20183381

Traditional commercial bibliographic databases and indexes provide some access to hydrology materials produced by the government; however, these sources do not provide comprehensive coverage of relevant hydrologic publications. This paper discusses bibliographic information available from the federal government and state geological surveys, water resources agencies, and depositories. In addition to information in these databases, the paper describes the scope, styles of citing, subject terminology, and the ways these information sources are currently being searched, formally and informally, by hydrologists. Information available from the federal and state agencies and from the state depositories might be missed by limiting searches to commercially distributed databases.

Although potential drug-drug interactions (PDDIs) are a significant source of preventable drug-related harm, there is currently no single complete source of PDDI information. In the current study, all publically available sources of PDDI information that could be identified using a comprehensive and broad search were combined into a single dataset. The combined dataset merged fourteen different sources including 5 clinically-oriented information sources, 4 Natural Language Processing (NLP) Corpora, and 5 Bioinformatics/Pharmacovigilance information sources. As a comprehensive PDDI source, the merged dataset might benefit the pharmacovigilance text mining community by making it possible to compare the representativeness of NLP corpora for PDDI text extraction tasks, and specifying elements that can be useful for future PDDI extraction purposes. An analysis of the overlap between and across the data sources showed that there was little overlap. Even comprehensive PDDI lists such as DrugBank, KEGG, and the NDF-RT had less than 50% overlap with each other. Moreover, all of the comprehensive lists had incomplete coverage of two data sources that focus on PDDIs of interest in most clinical settings. Based on this information, we think that systems that provide access to the comprehensive lists, such as APIs into RxNorm, should be careful to inform users that the lists may be incomplete with respect to PDDIs that drug experts suggest clinicians be aware of. In spite of the low degree of overlap, several dozen cases were identified where PDDI information provided in drug product labeling might be augmented by the merged dataset. Moreover, the combined dataset was also shown to improve the performance of an existing PDDI NLP pipeline and a recently published PDDI pharmacovigilance protocol. Future work will focus on improvement of the methods for mapping between PDDI information sources, identifying methods to improve the use of the merged dataset in PDDI NLP algorithms, integrating high-quality PDDI information from the merged dataset into Wikidata, and making the combined dataset accessible as Semantic Web Linked Data.

The Chandra Source Catalog (CSC) represents a reanalysis of the entire ACIS and HRC imaging observations over the 9-year Chandra mission. We describe here the method by which fluxes are measured for detected sources. Source detection is carried out on a uniform basis, using the CIAO tool wavdetect. Source fluxes are estimated post-facto using a Bayesian method that accounts for background, spatial resolution effects, and contamination from nearby sources. We use gamma-function prior distributions, which could be either non-informative, or in case there exist previous observations of the same source, strongly informative. The current implementation is however limited to non-informative priors. The resulting posterior probability density functions allow us to report the flux and a robust credible range on it.

Identification of information types and sources by the public for promoting awareness of Middle East respiratory syndrome coronavirus in Saudi Arabia.

Middle East Respiratory Syndrome (MERS) is a viral respiratory disease of serious consequences caused by MERS Coronavirus (MERS-CoV). Saudi communities still lack awareness of available protective measures to prevent the transmission of the virus. It is necessary to explore the current information-seeking strategies and preferences for communication tools among the Saudi population to promote dissemination of accurate information. Guided by McGuire's Input-Output Persuasion Model and focusing on input variables (receiver characteristics, sources, message, channel and destination), we explored the current information-seeking strategies and preferences for different communication tools among residents of Riyadh (n = 658). Preferred and sought-after information sources on MERS. Most participants in the sample were female (61.7%), and the majority (98.2%) had internet access at home. The internet was the most commonly used source of information (39.5%) and the most endorsed channel for a MERS awareness campaign. Physicians were the preferred source of information (45.6%), followed by other health care providers (31.3%). In univariate multinomial logistic regression models, males and individuals aged ≤27 years were more likely to seek information from the internet than from physicians. Residents of southern and western Riyadh preferred physicians as a credible source of information over the Ministry of Health. The results of this survey provide valuable information on how to reach this population and for understanding how to launch an effective MERS risk communication campaign in a Saudi population. © The Author 2015.

What Kind of Information About Marginal Donors Is Available Through Sources Other Than Health Care Professionals for Patients on the Waiting List for Organ Transplantation?

PubMed

Kamran, Sara; Calmus, Yvon; Pomey, Marie Pascale; Vidal-Trécan, Gwenaëlle

The current organ shortage has necessitated expanding the criteria for potential donations to marginal donors (older or sick donors whose organs would have been considered unsuitable before). In France, physicians are not required to provide information to recipients about marginal donors except for hepatitis C or hepatitis B infection and non-heart-beating donations. We hypothesized that patients can be informed about these risks by other information sources than health care professionals, such as websites and patient associations. The objectives of the study were to identify the main health information sources of transplant patients other than health professionals and to evaluate the information provided by websites and associations to patients about the risks of transplantation from marginal donors. In this study, the information sources for kidney, liver, heart, and lung patients that had already received transplants or registered on waiting lists were identified by a survey in four transplant centers. Further, the information proposed by French and English language websites and patient associations were evaluated, respectively, by a systematic review of websites and a survey among the presidents of kidney, liver, heart, and lung patient associations. For the first survey, (367/402) 91.3% responses were registered. Apart from health professionals identified as the principal information source (363/367) 98.9%, 19 liver and 28 heart patients searched for information on the websites, while 37 kidney and 42 lung patients were more informed by patients' associations. Our two last surveys showed that information about marginal donors is accessible by websites and (10/34) 30% of associations. All of the 60 Internet documents evaluated on French language and English language websites proposed information about marginal donors. Otherwise, (52/65) 80% of these documents were dedicated to health professionals and contained specialized information, difficult to understand by patients. Certain associations, (20/34) 59%, provided information about the risks of transplantation. There were 45/115 patients considering associations as their main information source that were informed by an association's website. However, only (5/22) 23% of associations communicated the risks of transplantation with patients through their websites. Currently, patients want to be more informed by other information sources than health professionals, particularly by the websites. Nevertheless, they cannot always trust information proposed by these sources. They need to have their physicians inform them about specialized keywords and present them with reliable information sources. So reliable centers such as universities, transplant centers, and associations should develop the quality and quantity of information proposed to patients on their websites.

Extending FDA guidance to include consumer medication information (CMI) delivery on mobile devices.

PubMed

Sage, Adam; Blalock, Susan J; Carpenter, Delesha

This paper describes the current state of consumer-focused mobile health application use and the current U.S. Food and Drug Administration (FDA) guidance on the distribution of consumer medication information (CMI), and discusses recommendations and considerations for the FDA to expand CMI guidance to include CMI in mobile applications. Smartphone-based health interventions have been linked to increased medication adherence and improved health outcomes. Trends in smartphone ownership present opportunities to more effectively communicate and disseminate medication information; however, current FDA guidance for CMI does not outline how to effectively communicate CMI on a mobile platform, particularly in regards to user-centered design and information sourcing. As evidence supporting the potential effectiveness of mobile communication in health care continues to increase, CMI developers, regulating entities, and researchers should take note. Although mobile-based CMI offers an innovative mechanism to deliver medication information, caution should be exercised. Specifically, considerations for developing mobile CMI include consumers' digital literacy, user experience (e.g., usability), and the quality and accuracy of new widely used sources of information (e.g., crowd-sourced reviews and ratings). Recommended changes to FDA guidance for CMI include altering the language about scientific accuracy to address more novel methods of information gathering (e.g., anecdotal experiences and Google Consumer Surveys) and including guidance for usability testing of mobile health applications.

The application and value of information sources in clinical practice: an examination of the perspective of naturopaths.

Steel, Amie; Adams, Jon

2011-06-01

The approach of evidence-based medicine (EBM), providing a paradigm to validate information sources and a process for critiquing their value, is an important platform for guiding practice. Researchers have explored the application and value of information sources in clinical practice with regard to a range of health professions; however, naturopathic practice has been overlooked. An exploratory study of naturopaths' perspectives of the application and value of information sources has been undertaken. Semi-structured interviews with 12 naturopaths in current clinical practice, concerning the information sources used in clinical practice and their perceptions of these sources. Thematic analysis identified differences in the application of the variety of information sources used, depending upon the perceived validity. Internet databases were viewed as highly valid. Textbooks, formal education and interpersonal interactions were judged based upon a variety of factors, whilst validation of general internet sites and manufacturers information was required prior to use. The findings of this study will provide preliminary aid to those responsible for supporting naturopaths' information use and access. In particular, it may assist publishers, medical librarians and professional associations in developing strategies to expand the clinically useful information sources available to naturopaths. © 2011 The authors.

Pangenesis as a source of new genetic information. The history of a now disproven theory.

PubMed

Bergman, Gerald

2006-01-01

Evolution is based on natural selection of existing biological phenotypic traits. Natural selection can only eliminate traits. It cannot create new ones, requiring a theory to explain the origin of new genetic information. The theory of pangenesis was a major attempt to explain the source of new genetic information required to produce phenotypic variety. This theory, advocated by Darwin as the main source of genetic variety, has now been empirically disproved. It is currently a theory mainly of interest to science historians.

Central and peripheral information source use among rural and remote Registered Nurses.

Kosteniuk, Julie G; D'Arcy, Carl; Stewart, Norma; Smith, Barbara

2006-07-01

This paper reports a study examining the use of central (colleagues, inservice and newsletters) and peripheral information sources (Internet, library, journal subscriptions and continuing education) among a large sample of rural and remote nurses and explores the factors associated with the use of particular peripheral information sources. There have been few studies of the specific sources of information accessed by Registered Nurses, particularly rural or remote nurses, and the characteristics of nurses and their organizations that are associated with the use of particular information sources. A questionnaire survey was conducted with 3933 Registered Nurses from all regions of rural and remote Canada between October 2001 and July 2002. We used frequencies and cross-tabulations to describe rates of information use, and forward selection logistic regression with likelihood ratio selection to build the best-fitting model of the variables that affected the odds of using each peripheral information source. Nursing colleagues ranked as the information source most frequently used, and the Internet and library ranked lowest. On average, nurses used a statistically significantly greater number of central than peripheral sources. Peripheral information source use was higher among nurses who had access to current information, opportunities to share their knowledge with others, higher education levels, were in positions of authority and worked with healthcare students. The associations between age and geographical location varied according to the peripheral information source under consideration. The vast majority of rural and remote nurses used at least one peripheral information source to inform their practice. Increasing the number of research sources used by these nurses requires attention to issues of information access in these areas, as well as issues of staff recruitment and retention of staff in under-serviced rural and remote regions.

Use of the World Wide Web in Lower-Division Chemistry Courses

NASA Astrophysics Data System (ADS)

Stevens, Karen E.; Stevens, Richard E.

1996-10-01

Recent articles have identified the plethora of chemical information existing currently on the World-Wide Web (WWW) available via the Internet (1). This information medium is particularly valuable because it represents a very up-to-date source of information. Site managers can update information and it can be "instantaneously visited" by someone. As an example, several current topics of chemical significance were highlighted in a nonmajor chemistry class held in January 1996 at our college. December 31, 1995, represented the last day that leaded gasoline could be sold for use in automobiles. In early January, the FDA approved the synthetic fat olestra for use in snack foods. Both of these topics provoked great interest in students as they brought up issues of relevance and interest to their lives that were currently being discussed in the news. The WWW was utilized extensively as a source of information and current updates. Print media, such as texts and reference manuals, have a much longer "lag-time" before current information can be typeset, printed, and accessed by a researcher. Previous articles (1, 2) have focused on Internet use for upper-division classes, but we have found a useful way to bring the Internet into nonmajor and freshman level classes composed of 20-50 students. The student assignment was to find information on a chemical topic currently in the news by using the WWW and use that information to write a 2-3 page essay (3, 4). Using the Internet to find information presents one issue not previously encountered when using encyclopedias, reference books, or textbooks, but an issue raised in previous editorials in this Journal (5, 6). That difference is that virtually anyone can post information on the WWW. Thus, the WWW can have governmental organizations, environmental groups, large corporations, or just individuals posting their views. Hence, when searching a particular topic, students might find a very factual article, or they might find a very biased opinion statement posted on the Internet by some person or group. Since there is no referee, virtually anything can be (and often is) found on the WWW. Rather than simply "telling students the answer", it is useful to encourage students to think analytically in order to be better informed consumers in our technological society. In these classes, students were required to write an essay detailing an issue of scientific interest currently being discussed in the news. Students were allowed to choose any web site as their source and were then required to determine the validity of that source by comparing and contrasting the views and facts presented there with some other source. By systematically working through the factual information (if any!) identified by the Internet source, the students were able to ascertain whether the claim was an exaggeration, or was a valid interpretation of the data. Students reported spending between 3 and 10 hours searching the WWW for this information. The essays written by the students were expected to consist of three major components: a background information section, a discussion of the information presented on the WWW, and an analysis section in which the student critiques the information found from a source on the WWW. This assignment worked well to bring the Internet and information from the WWW into the course. The students overwhelmingly enjoyed this assignment and actually looked forward to writing their next essay. They felt a tremendous amount of self-confidence in being able to judge the claims made by some corporations/groups that might otherwise have been misleading. These students were becoming more informed consumers in the sense that they now could logically critique advertisements and articles presented in the media. Clearly, this is a goal we should desire in any literate adult in our society. Literature Cited Mounts, R. D. J. Chem. Educ. 1996, 73, 68-71. Tissue, B. M. J. Chem. Educ. 1996, 73, 65-68. Markman, R.

Detecting misinformation and knowledge conflicts in relational data

NASA Astrophysics Data System (ADS)

Levchuk, Georgiy; Jackobsen, Matthew; Riordan, Brian

2014-06-01

Information fusion is required for many mission-critical intelligence analysis tasks. Using knowledge extracted from various sources, including entities, relations, and events, intelligence analysts respond to commander's information requests, integrate facts into summaries about current situations, augment existing knowledge with inferred information, make predictions about the future, and develop action plans. However, information fusion solutions often fail because of conflicting and redundant knowledge contained in multiple sources. Most knowledge conflicts in the past were due to translation errors and reporter bias, and thus could be managed. Current and future intelligence analysis, especially in denied areas, must deal with open source data processing, where there is much greater presence of intentional misinformation. In this paper, we describe a model for detecting conflicts in multi-source textual knowledge. Our model is based on constructing semantic graphs representing patterns of multi-source knowledge conflicts and anomalies, and detecting these conflicts by matching pattern graphs against the data graph constructed using soft co-reference between entities and events in multiple sources. The conflict detection process maintains the uncertainty throughout all phases, providing full traceability and enabling incremental updates of the detection results as new knowledge or modification to previously analyzed information are obtained. Detected conflicts are presented to analysts for further investigation. In the experimental study with SYNCOIN dataset, our algorithms achieved perfect conflict detection in ideal situation (no missing data) while producing 82% recall and 90% precision in realistic noise situation (15% of missing attributes).

The UMLS Knowledge Sources: Tools for Building Better User Interfaces

Lindberg, Donald A. B.; Humphreys, Betsy L.

1990-01-01

The current focus of the National Library of Medicine's Unified Medical Language System (UMLS) project is the development, testing, and evaluation of the first versions of three new knowledge sources: the Metathesaurus, the Semantic Network, and the Information Sources Map. These three knowledge sources can be used by interface programs to conduct an intelligent interaction with the user and to make the conceptual link between the user's question and relevant machine-readable information. NLM is providing experimental copies of the initial versions of the UMLS knowledge sources in exchange for feedback on ways they can and should be improved. The hope is that the results of such experimentation will provide both immediate improvements in biomedical information service and useful suggestions for enhancements to the UMLS.

Early Warning and Outbreak Detection Using Social Networking Websites: The Potential of Twitter

NASA Astrophysics Data System (ADS)

de Quincey, Ed; Kostkova, Patty

Epidemic Intelligence is being used to gather information about potential diseases outbreaks from both formal and increasingly informal sources. A potential addition to these informal sources are social networking sites such as Facebook and Twitter. In this paper we describe a method for extracting messages, called "tweets" from the Twitter website and the results of a pilot study which collected over 135,000 tweets in a week during the current Swine Flu pandemic.

Inverter communications using output signal

Chapman, Patrick L.

Technologies for communicating information from an inverter configured for the conversion of direct current (DC) power generated from an alternative source to alternating current (AC) power are disclosed. The technologies include determining information to be transmitted from the inverter over a power line cable connected to the inverter and controlling the operation of an output converter of the inverter as a function of the information to be transmitted to cause the output converter to generate an output waveform having the information modulated thereon.

Racial and Ethnic Differences in Tobacco Information Seeking and Information Sources: Findings From the 2015 Health Information National Trends Survey.

Nguyen, Anh B; Robinson, Joelle; O'Brien, Erin Keely; Zhao, Xiaoquan

2017-09-01

This article describes sources of health information, types of tobacco information sought, and trust in sources of tobacco information among U.S. racial/ethnic groups (Whites, Blacks, Hispanics, Asian and Pacific Islanders, and Other). Cross-sectional data (N = 3,788) from a nationally representative survey, HINTS-FDA 2015, were analyzed to examine unadjusted and adjusted associations between race/ethnicity and (a) first source of health information, (b) tobacco information seeking, and (c) trust in sources of tobacco information. Adjusted associations controlled for current tobacco product use and sociodemographic variables. Findings indicated that the Internet was the most common first source of health information while health care providers were the second most common source for all racial/ethnic groups. Tobacco-related health information seeking was more prevalent than other tobacco product information seeking. Unadjusted analyses indicated that a higher proportion of Whites sought other tobacco product information compared to Asians and Pacific Islanders. Trust was rated highest for doctors while trust for health organizations was rated second highest. Asians and Pacific Islanders had higher trust in the government compared to all other groups. Blacks had higher trust in religious organizations compared to all other groups besides Hispanics. Blacks had higher trust for tobacco companies compared to Whites and Other. Many of these differences were attenuated in adjusted analyses. This research has implications for tobacco control practice and policymaking by identifying potential dissemination strategies.

Consumer Perception of Genetically Modified Organisms and Sources of Information123

PubMed Central

Wunderlich, Shahla; Gatto, Kelsey A

2015-01-01

Genetically modified organisms (GMOs) have been available for commercial purchase since the 1990s, allowing producers to increase crop yields through bioengineering that creates herbicide-resistant and insect-resistant varieties. However, consumer knowledge about GMOs has not increased at the same rate as the adoption of GMO crops. Consumers worldwide are displaying limited understanding, misconceptions, and even unfamiliarity with GMO food products. Many consumers report that they receive information about GMO food products from the media, Internet, and other news sources. These sources may be less reliable than scientific experts whom consumers trust more to present the facts. Although many in the United States support mandatory GMO labeling (similar to current European standards), consumer awareness of current GMO labeling is low. A distinction must also be made between GMO familiarity and scientific understanding, because those who are more familiar with it tend to be more resistant to bioengineering, whereas those with higher scientific knowledge scores tend to have less negative attitudes toward GMOs. This brings to question the relation between scientific literacy, sources of information, and overall consumer knowledge and perception of GMO foods. PMID:26567205

A medical digital library to support scenario and user-tailored information retrieval.

PubMed

Chu, W W; Johnson, D B; Kangarloo, H

2000-06-01

Current large-scale information sources are designed to support general queries and lack the ability to support scenario-specific information navigation, gathering, and presentation. As a result, users are often unable to obtain desired specific information within a well-defined subject area. Today's information systems do not provide efficient content navigation, incremental appropriate matching, or content correlation. We are developing the following innovative technologies to remedy these problems: 1) scenario-based proxies, enabling the gathering and filtering of information customized for users within a pre-defined domain; 2) context-sensitive navigation and matching, providing approximate matching and similarity links when an exact match to a user's request is unavailable; 3) content correlation of documents, creating semantic links between documents and information sources; and 4) user models for customizing retrieved information and result presentation. A digital medical library is currently being constructed using these technologies to provide customized information for the user. The technologies are general in nature and can provide custom and scenario-specific information in many other domains (e.g., crisis management).

2013-01-01

Objective To characterize question types that residents received on overnight shifts and what information sources were used to answer them. Materials and Methods Across 30 overnight shifts, questions asked of on-call senior residents, question askers’ roles, and residents’ responses were documented. External sources were noted. Results 158 of 397 questions (39.8%) related to the plan of care, 53 (13.4%) to medical knowledge, 48 (12.1%) to taskwork knowledge, and 44 (11.1%) to the current condition of patients. For 351 (88.4%) questions residents provided specific, direct answers or visited the patient. For 16 of these, residents modeled or completed the task. For 216 questions, residents used previous knowledge or their own clinical judgment. Residents solicited external information sources for 118 questions and only a single source for 77 (65.3%) of them. For the 118, most questions concerned either the plan of care or the patient's current condition and were asked by interns and nurses (those with direct patient care responsibilities). Discussion Resident physicians serve as an information system and they often specifically answer the question using previous knowledge or their own clinical judgment, suggesting that askers are contacting an appropriately knowledgeable person. However, they do need to access patient information such as the plan of care. They also serve an educator role and answer many knowledge-related questions. Conclusions As synchronous verbal communications continue to be important pathways for information flow, informaticians need to consider the relationship between such communications and workflow in the development of healthcare support tools.

Cramer, Emily M.

2016-01-01

Given the importance of paternal involvement in maternal and child health, the current investigation takes a closer look at expectant and recent (E/R) fathers’ health information behavior during pregnancy, childbirth, and child care. A total of 186 E/R fathers (68 low-income) completed a survey gauging information needs, sources of information, and information-seeking behavior. Results are summarized in four statements that may help low-income E/R fathers get the information they need during a partner’s pregnancy or after a child is born: (a) paternal information needs are diverse, (b) information needs change across stages of child development, (c) interpersonal sources are important before and after birth, and (d) relationships matter.

Adaptive sampling of information in perceptual decision-making.

PubMed

Cassey, Thomas C; Evens, David R; Bogacz, Rafal; Marshall, James A R; Ludwig, Casimir J H

2013-01-01

In many perceptual and cognitive decision-making problems, humans sample multiple noisy information sources serially, and integrate the sampled information to make an overall decision. We derive the optimal decision procedure for two-alternative choice tasks in which the different options are sampled one at a time, sources vary in the quality of the information they provide, and the available time is fixed. To maximize accuracy, the optimal observer allocates time to sampling different information sources in proportion to their noise levels. We tested human observers in a corresponding perceptual decision-making task. Observers compared the direction of two random dot motion patterns that were triggered only when fixated. Observers allocated more time to the noisier pattern, in a manner that correlated with their sensory uncertainty about the direction of the patterns. There were several differences between the optimal observer predictions and human behaviour. These differences point to a number of other factors, beyond the quality of the currently available sources of information, that influences the sampling strategy.

Internet information-seeking in mental health: population survey.

Powell, John; Clarke, Aileen

2006-09-01

A major use of the of the internet is for health information-seeking. There has been little research into its use in relation to mental health. To investigate the prevalence of internet use for mental health information-seeking and its relative importance as a mental health information source. General population survey. Questions covered internet use, past psychiatric history and the 12-item General Health Questionnaire. Eighteen per cent of all internet users had used the internet for information related to mental health. The prevalence was higher among those with a past history of mental health problems and those with current psychological distress. Only 12% of respondents selected the internet as one of the three most accurate sources of information, compared with 24% who responded that it was one of the three sources they would use. The internet has a significant role in mental health information-seeking. The internet is used more than it is trusted.

Partial independence of bioelectric and biomagnetic fields and its implications for encephalography and cardiography

NASA Astrophysics Data System (ADS)

Irimia, Andrei; Swinney, Kenneth R.; Wikswo, John P.

2009-05-01

In this paper, we clearly demonstrate that the electric potential and the magnetic field can contain different information about current sources in three-dimensional conducting media. Expressions for the magnetic fields of electric dipole and quadrupole current sources immersed in an infinite conducting medium are derived, and it is shown that two different point dipole distributions that are electrically equivalent have different magnetic fields. Although measurements of the electric potential are not sufficient to determine uniquely the characteristics of a quadrupolar source, the radial component of the magnetic field can supply the additional information needed to resolve these ambiguities and to determine uniquely the configuration of dipoles required to specify the electric quadrupoles. We demonstrate how the process can be extended to even higher-order terms in an electrically silent series of magnetic multipoles. In the context of a spherical brain source model, it has been mathematically demonstrated that the part of the neuronal current generating the electric potential lives in the orthogonal complement of the part of the current generating the magnetic potential. This implies a mathematical relationship of complementarity between electroencephalography and magnetoencephalography, although the theoretical result in question does not apply to the nonspherical case [G. Dassios, Math. Med. Biol. 25, 133 (2008)]. Our results have important practical applications in cases where electrically silent sources that generate measurable magnetic fields are of interest. Moreover, electrically silent, magnetically active moments of higher order can be useful when cancellation due to superposition of fields can occur, since this situation leads to a substantial reduction in the measurable amplitude of the signal. In this context, information derived from magnetic recordings of electrically silent, magnetically active multipoles can supplement electrical recordings for the purpose of studying the physiology of the brain. Magnetic fields of the electric multipole sources in a conducting medium surrounded by an insulating spherical shell are also presented and the relevance of this calculation to cardiographic and encephalographic experimentation is discussed.

The current article is dedicated to application of Internet for acquisition of medical geography information. The vast majority of the modern domestic reference manuals are neither reliable nor up-to-date. At the time when the foreign printed sources are not easily accessible the foreign web resources often become the main source of information. The article possesses some practical advice on how to find the general, medical and military medical data on the web. It is emphasized the necessity of careful cross validation of all the obtained data to be confident in their reliability.

Real-time Data Streams from ``e-RemoteCtrl'' to Central VLBI Network Status Monitoring Services Like IVS Live

NASA Astrophysics Data System (ADS)

Neidhardt, Alexander; Collioud, Arnaud

2014-12-01

A central VLBI network status monitoring can be realized by using online status information about current VLBI sessions, real-time, and status data directly from each radio telescope. Such monitoring helps to organize sessions or to get immediate feedback from the active telescopes. Therefore the remote control software for VLBI radio telescopes ``e-RemoteCtrl'' (http://www.econtrol-software.de), which enables remote access as extension to the NASA Field System, realizes real-time data streams to dedicated data centers. The software has direct access to the status information about the current observation (e.g., schedule, scan, source) and the telescope (e.g., current state, temperature, pressure) in real-time. This information are directly sent to ``IVS Live''. ``IVS Live'' (http://ivslive.obs.u-bordeaux1.fr/) is a Web tool that can be used to follow the observing sessions, organized by the International VLBI Service for Geodesy and Astrometry (IVS), navigate through past or upcoming sessions, or search and display specific information about sessions, sources (like VLBI images), and stations, by using an Internet browser.

Role of Information Anxiety and Information Load on Processing of Prescription Drug Information Leaflets.

Bapat, Shweta S; Patel, Harshali K; Sansgiry, Sujit S

2017-10-16

In this study, we evaluate the role of information anxiety and information load on the intention to read information from prescription drug information leaflets (PILs). These PILs were developed based on the principals of information load and consumer information processing. This was an experimental prospective repeated measures study conducted in the United States where 360 (62% response rate) university students (>18 years old) participated. Participants were presented with a scenario followed by exposure to the three drug product information sources used to operationalize information load. The three sources were: (i) current practice; (ii) pre-existing one-page text only; and (iii) interventional one-page prototype PILs designed for the study. Information anxiety was measured as anxiety experienced by the individual when encountering information. The outcome variable of intention to read PILs was defined as the likelihood that the patient will read the information provided in the leaflets. A survey questionnaire was used to capture the data and the objectives were analyzed by performing a repeated measures MANOVA using SAS version 9.3. When compared to current practice and one-page text only leaflets, one-page PILs had significantly lower scores on information anxiety ( p < 0.001) and information load ( p < 0.001). The intention to read was highest and significantly different ( p < 0.001) for PILs as compared to current practice or text only leaflets. Information anxiety and information load significantly impacted intention to read ( p < 0.001). Newly developed PILs increased patient's intention to read and can help in improving the counseling services provided by pharmacists.

The intention to read was highest and significantly different (p < 0.001) for PILs as compared to current practice or text only leaflets. Information anxiety and information load significantly impacted intention to read (p < 0.001). Newly developed PILs increased patient’s intention to read and can help in improving the counseling services provided by pharmacists. PMID:29035337

Using grey literature to prepare pharmacy students for an evolving healthcare delivery system.

Happe, Laura E; Walker, Desiree'

2013-05-13

To assess the impact of using "grey literature" (information internally produced in print or electronic format by agencies such as hospitals, government, businesses, etc) rather than a textbook in a course on healthcare delivery systems on students' perception of the relevance of healthcare delivery system topics and their ability to identify credible sources of this information. A reading from the grey literature was identified and assigned to the students for each topic in the course. Pre- and post-course survey instruments were used for the assessment. Students reported healthcare delivery systems topics to be moderately relevant to the profession of pharmacy on both the pre- and post-course survey instruments. Students' knowledge of current and credible sources of information on healthcare delivery system topics significantly improved based on self-reports and scores on objective assessments (p<0.05). Assignment of grey literature in a course on healthcare delivery systems can be used to ensure that information in the pharmacy school curriculum is the most current and credible information available.

The "New Public" and the "Good Ol' Press": Evaluating Online News Sources During the 2013 Polio Outbreak in Israel.

Gesser-Edelsburg, Anat; Walter, Nathan; Shir-Raz, Yaffa

2017-02-01

The current research focuses on the 2013 polio outbreak in Israel as a case study to analyze the sources of information used in new media platforms, examining whether the new media have changed the ways in which we communicate about health issues. Specifically, we tracked and coded polio-related references on Hebrew news websites, blogs, forums, and Facebook posts. Overall, 24,388 polio-related references constituted our sampling frame. The findings suggest that there is a moderate-level correlation between the platform and the type of sources chosen by users. Beyond the differences between various platforms, we found that online information platforms rely not only on popular or pseudoscientific sources, but also on high-quality information. In fact, the analysis indicates that online news websites, forums, blogs, and Facebook posts create a unique blend of information, including scientific literature, medical professionals, and government representatives, as well as pseudoscientific research. These findings suggest a more optimistic view of the Internet as a source for health-related information in times of crises. Although the fact that members of the public are exposed to scientific sources does not indicate to what degree this affects their actual decision making. Exposure to a wider variety of sources may enhance health literacy, resulting in a better understanding of information needed to make informed decisions.

Consumer perception of genetically modified organisms and sources of information.

PubMed

Wunderlich, Shahla; Gatto, Kelsey A

2015-11-01

Genetically modified organisms (GMOs) have been available for commercial purchase since the 1990s, allowing producers to increase crop yields through bioengineering that creates herbicide-resistant and insect-resistant varieties. However, consumer knowledge about GMOs has not increased at the same rate as the adoption of GMO crops. Consumers worldwide are displaying limited understanding, misconceptions, and even unfamiliarity with GMO food products. Many consumers report that they receive information about GMO food products from the media, Internet, and other news sources. These sources may be less reliable than scientific experts whom consumers trust more to present the facts. Although many in the United States support mandatory GMO labeling (similar to current European standards), consumer awareness of current GMO labeling is low. A distinction must also be made between GMO familiarity and scientific understanding, because those who are more familiar with it tend to be more resistant to bioengineering, whereas those with higher scientific knowledge scores tend to have less negative attitudes toward GMOs. This brings to question the relation between scientific literacy, sources of information, and overall consumer knowledge and perception of GMO foods. © 2015 American Society for Nutrition.

The overarching goal of the NIF (Neuroscience Information Framework) project is to be a one-stop-shop for Neuroscience. This paper provides a technical overview of how the system is designed. The technical goal of the first version of the NIF system was to develop an information system that a neuroscientist can use to locate relevant information from a wide variety of information sources by simple keyword queries. Although the user would provide only keywords to retrieve information, the NIF system is designed to treat them as concepts whose meanings are interpreted by the system. Thus, a search for term should find a record containing synonyms of the term. The system is targeted to find information from web pages, publications, databases, web sites built upon databases, XML documents and any other modality in which such information may be published. We have designed a system to achieve this functionality. A central element in the system is an ontology called NIFSTD (for NIF Standard) constructed by amalgamating a number of known and newly developed ontologies. NIFSTD is used by our ontology management module, called OntoQuest to perform ontology-based search over data sources. The NIF architecture currently provides three different mechanisms for searching heterogeneous data sources including relational databases, web sites, XML documents and full text of publications. Version 1.0 of the NIF system is currently in beta test and may be accessed through http://nif.nih.gov. PMID:18958629

Bird, G; Heekin, J M

1994-01-01

This article presents the results of a survey conducted over the summer of 1992 on the use of information sources by professionals in the field of aging. In particular, factors affecting the use of electronic information sources were investigated. The data provide a demographic profile of North American gerontologists, with a predictably wide range of disciplines and types of practice represented. Several factors were found to have an impact on the gerontologists' utilization of electronic information sources. Respondents who used a larger-than-average number of computer applications were found to make relatively more use of electronic sources, including online searches, CD-ROM indexes, library OPACs, and other databases searched by remote access. Attendance at library workshops was found to increase the amount of end-user searching but not the amount of library-mediated searching. Respondents also reported which databases they used and which they considered most important. MEDLINE was the most frequently mentioned database across all disciplines, including the health and social sciences. Computer databases were ranked least important out of six listed sources of information, and only 5% of respondents reported having used an electronic current awareness profile.

Misleading by Omission: Rethinking the Obligation to Inform Research Subjects about Funding Sources.

PubMed

Manson, Neil C

2017-11-15

Informed consent requirements for medical research have expanded over the past half-century. The Declaration of Helsinki now includes an explicit positive obligation to inform subjects about funding sources. This is problematic in a number of ways and seems to oblige researchers to disclose information irrelevant to most consent decisions. It is argued here that such a problematic obligation involves an "informational fallacy." The aim in the second part of the paper is to provide a better approach to making sense of how a failure to inform about funding sources wrongs subjects: by making appeals to obligations to refrain from misleading by omission. This alternative approach-grounded in a general obligation to refrain from misleading, an obligation that is independent of informed consent-provides a basis for a norm that protects subjects' interests, without the informational fallacy. The approach developed here avoids the problems identified with the currently specified general obligation to inform about funding sources. © The Author 2017.

Lessons learned from a pilot implementation of the UMLS information sources map.

1995-01-01

To explore the software design issues involved in implementing an operational information sources map (ISM) knowledge base (KB) and system of navigational tools that can help medical users access network-based information sources relevant to a biomedical question. A pilot biomedical ISM KB and associated client-server software (ISM/Explorer) have been developed to help students, clinicians, researchers, and staff access network-based information sources, as part of the National Library of Medicine's (NLM) multi-institutional Unified Medical Language System (UMLS) project. The system allows the user to specify and constrain a search for a biomedical question of interest. The system then returns a list of sources matching the search. At this point the user may request 1) further information about a source, 2) that the list of sources be regrouped by different criteria to allow the user to get a better overall appreciation of the set of retrieved sources as a whole, or 3) automatic connection to a source. The pilot system operates in client-server mode and currently contains coded information for 121 sources. It is in routine use from approximately 40 workstations at the Yale School of Medicine. The lessons that have been learned are that: 1) it is important to make access to different versions of a source as seamless as possible, 2) achieving seamless, cross-platform access to heterogeneous sources is difficult, 3) significant differences exist between coding the subject content of an electronic information resource versus that of an article or a book, 4) customizing the ISM to multiple institutions entails significant complexities, and 5) there are many design trade-offs between specifying searches and viewing sets of retrieved sources that must be taken into consideration. An ISM KB and navigational tools have been constructed. In the process, much has been learned about the complexities of development and evaluation in this new environment, which are different from those for Gopher, wide area information servers (WAIS), World-Wide-Web (WWW), and MOSAIC resources.

Extending the testimony problem: evaluating the truth, scope, and source of cultural information.

PubMed

Bergstrom, Brian; Moehlmann, Bianca; Boyer, Pascal

2006-01-01

Children's learning--in the domains of science and religion specifically, but in many other cultural domains as well--relies extensively on testimony and other forms of culturally transmitted information. The cognitive processes that enable such learning must also administrate the evaluation, qualification, and storage of that information, while guarding against the dangers of false or misleading input. Currently, the development of these appraisal processes is not clearly understood. Recent work, reviewed here, has begun to address three important dimensions of the problem: how children and adults evaluate truth in communication, how they gauge the inferential potential of information, and how they encode and evaluate its source.

Synchronization Tomography: Modeling and Exploring Complex Brain Dynamics

NASA Astrophysics Data System (ADS)

Fieseler, Thomas

2002-03-01

Phase synchronization (PS) plays an important role both under physiological and pathological conditions. With standard averaging techniques of MEG data, it is difficult to reliably detect cortico-cortical and cortico-muscular PS processes that are not time-locked to an external stimulus. For this reason, novel synchronization analysis techniques were developed and directly applied to MEG signals. Of course, due to the lack of an inverse modeling (i.e. source localization), the spatial resolution of this approach was limited. To detect and localize cerebral PS, we here present the synchronization tomography (ST): For this, we first estimate the cerebral current source density by means of the magnetic field tomography (MFT). We then apply the single-run PS analysis to the current source density in each voxel of the reconstruction space. In this way we study simulated PS, voxel by voxel in order to determine the spatio-temporal resolution of the ST. To this end different generators of ongoing rhythmic cerebral activity are simulated by current dipoles at different locations and directions, which are modeled by slightly detuned chaotic oscillators. MEG signals for these generators are simulated for a spherical head model and a whole-head MEG system. MFT current density solutions are calculated from these simulated signals within a hemispherical source space. We compare the spatial resolution of the ST with that of the MFT. Our results show that adjacent sources which are indistinguishable for the MFT, can nevertheless be separated with the ST, provided they are not strongly phase synchronized. This clearly demonstrates the potential of combining spatial information (i.e. source localization) with temporal information for the anatomical localization of phase synchronization in the human brain.

Investigation of Magnetotelluric Source Effect Based on Twenty Years of Telluric and Geomagnetic Observation

Kis, A.; Lemperger, I.; Wesztergom, V.; Menvielle, M.; Szalai, S.; Novák, A.; Hada, T.; Matsukiyo, S.; Lethy, A. M.

Magnetotelluric method is widely applied for investigation of subsurface structures by imaging the spatial distribution of electric conductivity. The method is based on the experimental determination of surface electromagnetic impedance tensor (Z) by surface geomagnetic and telluric registrations in two perpendicular orientation. In practical explorations the accurate estimation of Z necessitates the application of robust statistical methods for two reasons:1) the geomagnetic and telluric time series' are contaminated by man-made noise components and2) the non-homogeneous behavior of ionospheric current systems in the period range of interest (ELF-ULF and longer periods) results in systematic deviation of the impedance of individual time windows.Robust statistics manage both load of Z for the purpose of subsurface investigations. However, accurate analysis of the long term temporal variation of the first and second statistical moments of Z may provide valuable information about the characteristics of the ionospheric source current systems. Temporal variation of extent, spatial variability and orientation of the ionospheric source currents has specific effects on the surface impedance tensor. Twenty year long geomagnetic and telluric recordings of the Nagycenk Geophysical Observatory provides unique opportunity to reconstruct the so called magnetotelluric source effect and obtain information about the spatial and temporal behavior of ionospheric source currents at mid-latitudes. Detailed investigation of time series of surface electromagnetic impedance tensor has been carried out in different frequency classes of the ULF range. The presentation aims to provide a brief review of our results related to long term periodic modulations, up to solar cycle scale and about eventual deviations of the electromagnetic impedance and so the reconstructed equivalent ionospheric source effects.

Ultimate Limit to the Spatial Resolution in Magnetic Imaging

NASA Astrophysics Data System (ADS)

Matthews, John; Wellstood, Frederick C.; Chatraphorn, Sojiphong

2003-03-01

Motivated by the continual improvement in the spatial resolution of source currents detected by magnetic field imaging, in particular scanning SQUID microscopy, we have determined a theoretical limit to the spatial resolution for a given set of parameters. The guiding principle here is that by adding known information (e.g. CAD diagram) about the source currents into the inversion algorithm, we reduce the number of unknown parameters and hence lower the uncertainty in the remaining parameters. We consider the ultimate limit to be the case where all the information about the system is known, except for a single parameter, e.g. the separation w of two long, straight wires each carrying a current I/2. For this particular example we find that for a current I=100;μA, with magnetic field noise Δ B=10 pT, at a standoff z=100;μm, the minimum resolvable separation is 2;μm, about an order of magnitude less than the present limit.

Testing the Auroral Current-Voltage Relation in Multiple Arcs

NASA Astrophysics Data System (ADS)

Cameron, T. G.; Knudsen, D. J.; Cully, C. M.

2013-12-01

The well-known current-voltage relation within auroral inverted-V regions [Knight, Planet. Space Sci., 21, 741, 1973] predicts current carried by an auroral flux tube given the total potential drop between a plasma-sheet source region and the ionosphere. Numerous previous studies have tested this relation using spacecraft that traverse auroral arcs at low (ionospheric) or mid altitudes. Typically, the potential drop is estimated at the peak of the inverted-V, and field-aligned current is estimated from magnetometer data; statistical information is then gathered over many arc crossings that occur over a wide range of source conditions. In this study we use electron data from the FAST satellite to examine the current-voltage relation in multiple arc sets, in which the key source parameters (plasma sheet density and temperature) are presumed to be identical. We argue that this approach provides a more sensitive test of the Knight relation, and we seek to explain remaining variability with factors other than source variability. This study is supported by a grant from the Natural Sciences and Engineering Research Council of Canada.

Weighted minimum-norm source estimation of magnetoencephalography utilizing the temporal information of the measured data

NASA Astrophysics Data System (ADS)

Iwaki, Sunao; Ueno, Shoogo

1998-06-01

The weighted minimum-norm estimation (wMNE) is a popular method to obtain the source distribution in the human brain from magneto- and electro- encephalograpic measurements when detailed information about the generator profile is not available. We propose a method to reconstruct current distributions in the human brain based on the wMNE technique with the weighting factors defined by a simplified multiple signal classification (MUSIC) prescanning. In this method, in addition to the conventional depth normalization technique, weighting factors of the wMNE were determined by the cost values previously calculated by a simplified MUSIC scanning which contains the temporal information of the measured data. We performed computer simulations of this method and compared it with the conventional wMNE method. The results show that the proposed method is effective for the reconstruction of the current distributions from noisy data.

Communication to patients of information about their disease has become increasingly important in modern medicine, and particularly with chronic nonfatal disorders like inflammatory bowel disease (IBD), but the subject is not adequately researched or understood. We studied the media and preferences for communication of information in a multi-national community-based inception cohort of European and Israeli patients with IBD and 10 years follow-up, using structured questionnaires categorizing demographics, disease status, current and preferred sources of information, use of electronic media, role of patients' associations, and satisfaction level. The 917 patients completing the questionnaire were derived from northern (60%) and southern (40%) countries. The mean age was 48.3 years (62% under 50 years); 51% were males; 67% had ulcerative colitis, 33% Crohn's disease. Sixty-six percent of patients designated the specialist as their primary source of information, 77% indicated satisfaction with their current information, and 65% reported not receiving information about medical treatment in the past year. Patient concerns were about new research into their illness (64%), medical treatments (58%), risks and complications (51%) and genetics (42%). Preferred sources of information were paper bulletin (76%), electronic media (30%) and international organization (79%). Diagnosis (ulcerative colitis or Crohn's disease), gender, education level and country impacted significantly on patients' choices. In providing health care information to patients with IBD their individual attitudes and preferences must be considered. There should be greater roles for IBD patients' associations and international IBD-research organizations, and an increasing use of electronic media.

Under certain conditions time reversal is a promising method to determine earthquake source characteristics without any a-priori information (except the earth model and the data). It consists of injecting flipped-in-time records from seismic stations within the model to create an approximate reverse movie of wave propagation from which the location of the source point and other information might be inferred. In this study, the backward propagation is performed numerically using a spectral element code. We investigate the potential of time reversal to recover finite source characteristics (e.g., size of ruptured area, location of asperities, rupture velocity etc.). We use synthetic data from the SPICE kinematic source inversion blind test initiated to investigate the performance of current kinematic source inversion approaches (http://www.spice- rtn.org/library/valid). The synthetic data set attempts to reproduce the 2000 Tottori earthquake with 33 records close to the fault. We discuss the influence of relaxing the ignorance to prior source information (e.g., origin time, hypocenter, fault location, etc.) on the results of the time reversal process.

The growing awareness of the environmental significance of fine-grained sediment fluxes through catchment systems continues to underscore the need for reliable information on the principal sources of this material. Source estimates are difficult to obtain using traditional monitoring techniques, but sediment source fingerprinting or tracing procedures, have emerged as a potentially valuable alternative. Despite the rapidly increasing numbers of studies reporting the use of sediment source fingerprinting, several key challenges and uncertainties continue to hamper consensus among the international scientific community on key components of the existing methodological procedures. Accordingly, this contribution reviews and presents recent developments for several key aspects of fingerprinting, namely: sediment source classification, catchment source and target sediment sampling, tracer selection, grain size issues, tracer conservatism, source apportionment modelling, and assessment of source predictions using artificial mixtures. Finally, a decision-tree representing the current state of knowledge is presented, to guide end-users in applying the fingerprinting approach.

Background Sources of sexual health information exert strong influence on adolescents’ sexual behavior. Purpose The current study was undertaken to understand how family serve as sexual information sources, the messages adolescents recall from family, and how family learning experiences affect sexual behavior among at-risk adolescents. Methods Individual interviews were conducted with 69 teens, ages 15–18 years, from an alternative high school and a juvenile correctional facility to capture adolescents’ early sexual health learning experiences involving family and evaluate their association with teens’ recent sexual behavior. Sexual learning narratives were compared among gender and sexual experience groups. Results Many participants identified family as sexual health information sources. Primary messages recalled: risks of sex, protection, and relationship advice. Many adolescents portrayed learning experiences as negative, cautionary, lacking detail and not always balanced with positive messages. Participants who reported four or more sexual risks were the only group to identify pornography as a sexual health information source. Participants who reported fewer than four sexual risks were most likely to identify family sexual health information sources. Discussion Participants identified family members as sources of sexual health information, with variations by gender. Negative/cautionary messages require teens to seek additional sexual information elsewhere (primarily friends/media). Males, in particular, appear to often lack familial guidance/education. Translation to Health Education Practice Sexual health messages should be tailored to adolescents’ needs for practical and sex-positive guidance regarding mechanics of sex and formation of healthy relationships, and balanced with cautions regarding negative consequences.

Information-Driven Active Audio-Visual Source Localization

Schult, Niclas; Reineking, Thomas; Kluss, Thorsten; Zetzsche, Christoph

2015-01-01

We present a system for sensorimotor audio-visual source localization on a mobile robot. We utilize a particle filter for the combination of audio-visual information and for the temporal integration of consecutive measurements. Although the system only measures the current direction of the source, the position of the source can be estimated because the robot is able to move and can therefore obtain measurements from different directions. These actions by the robot successively reduce uncertainty about the source’s position. An information gain mechanism is used for selecting the most informative actions in order to minimize the number of actions required to achieve accurate and precise position estimates in azimuth and distance. We show that this mechanism is an efficient solution to the action selection problem for source localization, and that it is able to produce precise position estimates despite simplified unisensory preprocessing. Because of the robot’s mobility, this approach is suitable for use in complex and cluttered environments. We present qualitative and quantitative results of the system’s performance and discuss possible areas of application. PMID:26327619

Fine Particulate Pollution and Source Apportionment in the Urban Centers for Africa, Asia and Latin America

Fossil fuel combustion for domestic cooking and heating, power generation, industrial processes, and motor vehicles are the primary sources of air pollution in the developing country cities. Over the past twenty years, major advances have been made in understanding the social and economic consequences of air pollution. In both industrialized and developing countries, it has been shown that air pollution from energy combustion has detrimental impacts on human health and the environment. Lack of information on the sectoral contributions to air pollution - especially fine particulates, is one of the typical constraints for an effective integrated urban air quality management program. Without such information, it is difficult, if not impossible, for decision makers to provide policy advice and make informed investment decisions related to air quality improvements in developing countries. This also raises the need for low-cost ways of determining the principal sources of fine PM for a proper planning and decision making. The project objective is to develop and verify a methodology to assess and monitor the sources of PM, using a combination of ground-based monitoring and source apportionment techniques. This presentation will focus on four general tasks: (1) Review of the science and current activities in the combined use of monitoring data and modeling for better understanding of PM pollution. (2) Review of recent advances in atmospheric source apportionment techniques (e.g., principal component analysis, organic markers, source-receptor modeling techniques). (3) Develop a general methodology to use integrated top-down and bottom-up datasets. (4) Review of a series of current case studies from Africa, Asia and Latin America and the methodologies applied to assess the air pollution and its sources.

2010-12-01

Local field potentials have good temporal resolution but are blurred due to the slow spatial decay of the electric field. For simultaneous recordings on regular grids one can reconstruct efficiently the current sources (CSD) using the inverse Current Source Density method (iCSD). It is possible to decompose the resultant spatiotemporal information about the current dynamics into functional components using Independent Component Analysis (ICA). We show on test data modeling recordings of evoked potentials on a grid of 4 × 5 × 7 points that meaningful results are obtained with spatial ICA decomposition of reconstructed CSD. The components obtained through decomposition of CSD are better defined and allow easier physiological interpretation than the results of similar analysis of corresponding evoked potentials in the thalamus. We show that spatiotemporal ICA decompositions can perform better for certain types of sources but it does not seem to be the case for the experimental data studied. Having found the appropriate approach to decomposing neural dynamics into functional components we use the technique to study the somatosensory evoked potentials recorded on a grid spanning a large part of the forebrain. We discuss two example components associated with the first waves of activation of the somatosensory thalamus. We show that the proposed method brings up new, more detailed information on the time and spatial location of specific activity conveyed through various parts of the somatosensory thalamus in the rat.

IntroductionInformation concerning the availability, use, and quality of water in Concordia Parish, Louisiana, is critical for proper water-supply management. The purpose of this fact sheet is to present information that can be used by water managers, parish residents, and others for stewardship of this vital resource. Information on the availability, past and current use, use trends, and water quality from groundwater and surface-water sources in the parish is presented. Previously published reports and data stored in the U.S. Geological Survey’s National Water Information System are the primary sources of the information presented here.In 2010, over 50 million gallons per day (Mgal/d) of water were withdrawn in Concordia Parish, including about 28.7 Mgal/d from groundwater sources and 22.3 Mgal/d from surface-water sources. Withdrawals for agricultural use, composed of livestock, rice irrigation, general irrigation, and aquaculture accounted for about 77 percent (39.2 Mgal/d) of the total water withdrawn. Other categories of use included public supply, power generation, and rural domestic. Water-use data collected at 5-year intervals from 1960 to 2010 indicated that water withdrawals peaked in 2010.

The current West Africa epidemic of Ebola virus disease (EVD), which began from Guinea in December 2013, has been the longest and deadliest Ebola outbreak to date. With the propagation of the internet, public health officials must now compete with other official and unofficial sources of information to get their message out. This study aimed at critically appraising videos available on one popular internet video site (YouTube) as a source of information for Ebola virus disease (EVD). Videos were searched in YouTube (http://www.youtube.com) using the keyword "Ebola outbreak" from inception to November 1, 2014 with the default "relevance" filter. Only videos in English language under 10 min duration within first 10 pages of search were included. Duplicates were removed and the rest were classified as useful or misleading by two independent reviewers. Video sources were categorized by source. Inter-observer agreement was evaluated with kappa coefficient. Continuous and categorical variables were analyzed using the Student t-test and Chi-squared test, respectively. One hundred and eighteen out of 198 videos were evaluated. Thirty-one (26.27%) videos were classified as misleading and 87 (73.73%) videos were classified as useful. The kappa coefficient of agreement regarding the usefulness of the videos was 0.68 (P < 0.001). Independent users were more likely to post misleading videos (93.55% vs 29.89%, OR = 34.02, 95% CI = 7.55-153.12, P < 0.001) whereas news agencies were most likely to post useful videos (65.52% vs 3.23%, OR = 57.00, 95% CI = 7.40-438.74, P < 0.001). This study demonstrates that majority of the internet videos about Ebola on YouTube were characterized as useful. Although YouTube seems to generally be a useful source of information on the current outbreak, increased efforts to disseminate scientifically correct information is desired to prevent unnecessary panic among the among the general population.

Broadcast media and the dissemination of weather information

1973-01-01

Although television is the public's most preferred source of weather information, it fails to provide weather reports to those groups who seek the information early in the day and during the day. The result is that many people most often use radio as a source of information, yet preferring the medium of television. The public actively seeks weather information from both radio and TV stations, usually seeking information on current conditions and short range forecasts. forecasts. Nearly all broadcast stations surveyed were eager to air severe weather bulletins quickly and often. Interest in Nowcasting was high among radio and TV broadcasters, with a significant portion indicating a willingness to pay something for the service. However, interest among TV stations in increasing the number of daily reports was small.

Transparent ICD and DRG coding using information technology: linking and associating information sources with the eXtensible Markup Language.

Hoelzer, Simon; Schweiger, Ralf K; Dudeck, Joachim

2003-01-01

With the introduction of ICD-10 as the standard for diagnostics, it becomes necessary to develop an electronic representation of its complete content, inherent semantics, and coding rules. The authors' design relates to the current efforts by the CEN/TC 251 to establish a European standard for hierarchical classification systems in health care. The authors have developed an electronic representation of ICD-10 with the eXtensible Markup Language (XML) that facilitates integration into current information systems and coding software, taking different languages and versions into account. In this context, XML provides a complete processing framework of related technologies and standard tools that helps develop interoperable applications. XML provides semantic markup. It allows domain-specific definition of tags and hierarchical document structure. The idea of linking and thus combining information from different sources is a valuable feature of XML. In addition, XML topic maps are used to describe relationships between different sources, or "semantically associated" parts of these sources. The issue of achieving a standardized medical vocabulary becomes more and more important with the stepwise implementation of diagnostically related groups, for example. The aim of the authors' work is to provide a transparent and open infrastructure that can be used to support clinical coding and to develop further software applications. The authors are assuming that a comprehensive representation of the content, structure, inherent semantics, and layout of medical classification systems can be achieved through a document-oriented approach.

"These issues aren't talked about at home": a qualitative study of the sexual and reproductive health information preferences of adolescents in Vanuatu.

2014-07-30

Onset of sexual activity during adolescence is common in Vanuatu, however access to comprehensive sexual and reproductive health (SRH) information is limited. Improving adolescents' knowledge about SRH is necessary to improve health outcomes, however little is known about the information needs and preferences of adolescents in the Pacific to inform policy and programs in this region. Sixty-six focus group discussions were conducted with 341 male and female adolescents aged 15-19 years from rural and urban communities on two islands of Vanuatu. Twelve key-informant interviews were also conducted with policymakers and health service providers. Data were analysed thematically using an inductive approach. Much of the SRH information targeting adolescents focused on sexually transmitted infections and HIV. While this information was valued, important gaps were identified including prevention of pregnancy, condom use, puberty, sexuality and relationships. Peer educators and health workers were adolescents' preferred sources of information because they were considered knowledgeable and trustworthy. Parents were not a common source but were preferred, particularly by girls, despite considerable socio-cultural barriers. Schools were an important but underutilised source of information, as were a range of media sources. Providing adolescents with comprehensive SRH information can have life-long protective benefits, however there are important content gaps in information currently provided in Vanuatu. The broad range of sources preferred by adolescents highlights the need to strengthen information provision through multiple channels to reach in and out-of-school youth and respond to individual needs and contexts.

Forrest, M; Robb, M

2000-09-01

The objective of this study was to find out more about the information needs of doctors-in-training and to identify their preferred sources of information. The methodology included interviews with consultants and administrators, a focus group discussion with library staff and a postal questionnaire sent to 347 doctors-in-training (there was a 43% return). The shortcomings of a questionnaire primarily composed of closed questions were addressed by the inclusion of one-to-one interviews which offered the opportunity for more in-depth commentary on specific issues highlighted in the questionnaire. Results indicated the frequency with which various types of information sources were consulted and how this related to the 'ease of access' of each information source. There was also the opportunity to comment on future information needs. It was clear from the interviews as well as comments made on the questionnaire that the two most important requirements for doctors-in-training were 'more time to find and obtain information' and 'better access to information sources when and where they are needed'. The results, although not surprising, included specific suggestions that have been used for the strategic planning of the library service to deliver the best possible support to users within the current framework of evidence-based medicine.

2002-01-01

Information technologies have the potential to affect the types and distribution of jobs in the health care workforce. Against a background of an explosively growing body of knowledge in the health sciences, current models of clinical decision making by autonomous practitioners, relying upon their memory and personal experience, will be inadequate for effective twenty-first-century health care delivery. The growth of consumerism and the proliferation of Internet-accessible sources of health-related information will modify the traditional roles of provider and patient and will provide opportunities for new kinds of employment in health-related professions.

Objective The aim of the present study was to audit the current use of medical records to determine completeness and concordance with other sources of medical information. Methods Medical records for 40 patients from each of five Melbourne major metropolitan hospitals were randomly selected (n=200). A quantitative audit was performed for detailed patient information and medical record keeping, as well as data collection, storage and utilisation. Using each hospital's current online clinical database, scanned files and paperwork available for each patient audited, the reviewers sourced as much relevant information as possible within a 30-min time allocation from both the record and the discharge summary. Results Of all medical records audited, 82% contained medical and surgical history, allergy information and patient demographics. All audited discharge summaries lacked at least one of the following: demographics, medication allergies, medical and surgical history, medications and adverse drug event information. Only 49% of records audited showed evidence the discharge summary was sent outside the institution. Conclusions The quality of medical data captured and information management is variable across hospitals. It is recommended that medical history documentation guidelines and standardised discharge summaries be implemented in Australian healthcare services. What is known about this topic? Australia has a complex health system, the government has approved funding to develop a universal online electronic medical record system and is currently trialling this in an opt-out style in the Napean Blue Mountains (NSW) and in Northern Queensland. The system was originally named the personally controlled electronic health record but has since been changed to MyHealth Record (2016). In Victoria, there exists a wide range of electronic health records used to varying degrees, with some hospitals still relying on paper-based records and many using scanned medical records. This causes inefficiencies in the recall of patient information and can potentially lead to incidences of adverse drug events. What does this paper add? This paper supports the concept of a shared medical record system using 200 audited patient records across five Victorian metropolitan hospitals, comparing the current information systems in place for healthcare practitioners to retrieve data. This research identifies the degree of concordance between these sources of information and in doing so, areas for improvement. What are the implications for practitioners? Implications of this research are the improvements in the quality, storage and accessibility of medical data in Australian healthcare systems. This is a relevant issue in the current Australian environment where no guidelines exist across the board in medical history documentation or in the distribution of discharge summaries to other healthcare providers (general practitioners, etc).

Promoting healthy gestational weight gain (GWG) is important for preventing obstetric and perinatal morbidity, along with obesity in both mother and child. Provision of GWG guidelines by health professionals predicts women meeting GWG guidelines. Research concerning women's GWG information sources is limited. This study assessed pregnant women's sources of GWG information and how, where and which women seek GWG information. Consecutive women (n = 1032) received a mailed questionnaire after their first antenatal visit to a public maternity hospital in Melbourne, Australia. Recalled provision of GWG guidelines by doctors and midwives, recalled provided GWG goals, and the obtaining of GWG information and information sources were assessed. Participants (n = 368; 35.7% response) averaged 32.5 years of age and 20.8 weeks gestation, with 33.7% speaking a language other than English. One in ten women recalled receiving GWG guidelines from doctors or midwives, of which half were consistent with Institute of Medicine guidelines. More than half the women (55.4%) had actively sought GWG information. Nulliparous (OR 7.07, 95% CI = 3.91-12.81) and obese (OR 1.96, 95% CI = 1.05-3.65) women were more likely to seek information. Underweight (OR 0.29, 95% CI = 0.09-0.97) women and those working part time (OR 0.52, 95% CI = 0.28-0.97) were less likely to seek information. Most frequently reported GWG sources included the internet (82.7%), books (55.4%) and friends (51.5%). The single most important sources were identified as the internet (32.8%), general practitioners (16.9%) and books (14.9%). More than half of women were seeking GWG guidance and were more likely to consult non-clinician sources. The small numbers given GWG targets, and the dominance of non-clinical information sources, reinforces that an important opportunity to provide evidence based advice and guidance in the antenatal care setting is currently being missed.

This paper discusses the measurements of the electromagnetic interference (EMI) generated during discharges of Mylar samples. The two components of EMI, the conducted emission and the radiated emission, are characterized by the replacement current and the radiated RF spectrum respectively. The measured radiated RF spectra reveal important information on the source of the electromagnetic radiation. The possible sources are the replacement current pulse and the discharged generated plasma. The scaling of the amplitudes of the EMI, as a function of the area of the test sample, is also discussed.

Bennett, William H.

The public information media provides information on current events (news), entertainment (programming), and opinions offered by trusted public sources (e.g., business, academic or religious spokespersons, journalists, and government officials). Consequently, it is a major force in shaping a populace's attitudes toward significant social issues and of great interest to intervention planners. The chapter attempts to provide modelers and intervention analysts alike with sufficient understanding of media mechanisms and current research that they can begin contributing to, and benefiting from this important area of study.

Benefits of Sharing Information from Commercial Airborne Forward-Looking Sensors in the Next Generation Air Transportation System

The air transportation system of the future will need to support much greater traffic densities than are currently possible, while preserving or improving upon current levels of safety. Concepts are under development to support a Next Generation Air Transportation System (NextGen) that by some estimates will need to support up to three times current capacity by the year 2025. Weather and other atmospheric phenomena, such as wake vortices and volcanic ash, constitute major constraints on airspace system capacity and can present hazards to aircraft if encountered. To support safe operations in the NextGen environment advanced systems for collection and dissemination of aviation weather and environmental information will be required. The envisioned NextGen Network Enabled Weather (NNEW) infrastructure will be a critical component of the aviation weather support services, providing access to a common weather picture for all system users. By taking advantage of Network Enabled Operations (NEO) capabilities, a virtual 4-D Weather Data Cube with aviation weather information from many sources will be developed. One new source of weather observations may be airborne forward-looking sensors, such as the X-band weather radar. Future sensor systems that are the subject of current research include advanced multi-frequency and polarimetric radar, a variety of Lidar technologies, and infrared imaging spectrometers.

Current developments in science and the media have now placed pregnant women in a precarious situation as they are charged with the responsibility to navigate through information sources to make the best decisions for her pregnancy. Yet little is known regarding how pregnant women want to receive and use health information in general, let alone information regarding the uncertain risks to pregnancy in everyday household products such as phthalates found in cosmetics and canned food liners. Using phthalates as an example, this study investigated how pregnant women obtain, evaluate, and act on information regarding their pregnancy. Pregnant women were recruited using pamphlets and posters distributed in prenatal clinics, prenatal fairs and physician offices in Southwestern Ontario Canada. Research participants were engaged in 20 to 40 min semi-structured interviews regarding their use of information sources in pregnancy, particularly regarding phthalates in cosmetics and canned food liners. Interviews were transcribed verbatim and analyzed using constructivist grounded theory techniques supported by NVivo 9™ software. Theoretical sufficiency was reached after 23 pregnant women were interviewed and their transcripts analyzed. Three overlapping themes resulted from the co-constructed analysis: I-Strength of Information Sources; II-Value Modifiers; and III-Deciding to Control Exposure. The research participants reported receiving information from a wide range of sources that they perceived varying in strength or believability. They then described the strategies employed to increase the validity of the message in order to avoid risk exposure. Pregnant women preferred a strong source of information such as physician, government but frequently used weak sources such as the internet or the opinions of friends. A model was developed from the relationship between themes that describes how pregnant women navigate the multiple sources of information available to them. Our study provides insight into how pregnant women receive, appraise, and act on information regarding everyday household chemicals. Clinicians and their professional organizations should produce specific educational materials to assist women in understanding exposure to everyday products in pregnancy.

It has been widely acknowledged that well-planned and executed communication programmes can contribute to achieving malaria prevention and treatment goals. This however requires a good understanding of current sources and roles of information used by both health workers and communities. The study aimed at determining health workers' and community members' sources, value and use of information on malaria prevention and treatment in Nigeria. Qualitative data was collected from six selected communities (three urban and three rural) in Enugu state, southeast Nigeria. A total of 18 Focus Group Discussions (FGDs) with 179 community members and 26 in-depth interviews (IDIs) with health workers in public and private health facilities were used to collect data on where people receive treatment for malaria and access information on malaria. The FGDS and IDIs also provided data on the values, uses and effects of information and communication on malaria treatment seeking and provision of services. The findings revealed that the major sources of information on malaria for health workers and community members were advertisements in the mass media, workshops and seminars organized by donor agencies, facility supervision, posters, other health workers, television and radio adverts. Community involvement in the design and delivery of information on malaria control was seen as a strong strategy for improving both consumer and provider knowledge. Information from the different sources catalyzed appropriate provision and consumption of malaria treatment amongst health workers and community members. Health workers and consumers receive information on malaria prevention and treatment from multiple sources of communication and information, which they find useful. Harnessing these information sources to encourage consistent and accurate messages around malaria prevention and treatment is a necessary first step in the design and implementation of malaria communication and behaviour change interventions and ultimately for the sustained control of malaria.

A study on locating the sonic source of sinusoidal magneto-acoustic signals using a vector method.

2015-01-01

Methods based on the magnetic-acoustic effect are of great significance in studying the electrical imaging properties of biological tissues and currents. The continuous wave method, which is commonly used, can only detect the current amplitude without the sound source position. Although the pulse mode adopted in magneto-acoustic imaging can locate the sonic source, the low measuring accuracy and low SNR has limited its application. In this study, a vector method was used to solve and analyze the magnetic-acoustic signal based on the continuous sine wave mode. This study includes theory modeling of the vector method, simulations to the line model, and experiments with wire samples to analyze magneto-acoustic (MA) signal characteristics. The results showed that the amplitude and phase of the MA signal contained the location information of the sonic source. The amplitude and phase obeyed the vector theory in the complex plane. This study sets a foundation for a new technique to locate sonic sources for biomedical imaging of tissue conductivity. It also aids in studying biological current detecting and reconstruction based on the magneto-acoustic effect.

The research determined (1) the information sources that family physicians (FPs) most commonly use to update their general medical knowledge and to make specific clinical decisions, and (2) the information sources FPs found to be most physically accessible, intellectually accessible (easy to understand), reliable (trustworthy), and relevant to their needs. A cross-sectional postal survey of 792 FPs and locum tenens, in full-time or part-time medical practice, currently practicing or on leave of absence in the Canadian province of Saskatchewan was conducted during the period of January to April 2008. Of 666 eligible physicians, 331 completed and returned surveys, resulting in a response rate of 49.7% (331/666). Medical textbooks and colleagues in the main patient care setting were the top 2 sources for the purpose of making specific clinical decisions. Medical textbooks were most frequently considered by FPs to be reliable (trustworthy), and colleagues in the main patient care setting were most physically accessible (easy to access). When making specific clinical decisions, FPs were most likely to use information from sources that they considered to be reliable and generally physically accessible, suggesting that FPs can best be supported by facilitating easy and convenient access to high-quality information.

Dr Google, porn and friend-of-a-friend: where are young men really getting their sexual health information?

Litras, Amy; Latreille, Sarah; Temple-Smith, Meredith

2015-11-01

Background Young men are vulnerable when it comes to sexual health. They attend the general practitioner (GP) less often than females and are less likely to be offered testing for sexually transmissible infections. Access to accurate health information and education is a cornerstone of primary prevention, yet we know very little about how, where and why young people obtain information about sexual health. One-on-one semi-structured interviews were conducted with 35 male students aged 16-19 years from two Victorian educational institutions for trade skills until data saturation was reached. Interviews were audio-recorded, transcribed and thematically analysed. The young men were poorly informed about sexual health. Their existing knowledge mainly came from school-based sexual health education, which while valued, was generally poorly recalled and provided only a narrow scope of physiological information. Young men seek sexual health information from various sources including family, the Internet, friends and pornography, with information from the latter three sources perceived as unreliable. GPs were seen as a source of trust-worthy information but were not accessed for this purpose due to embarrassment. Young men preferred the GP to initiate such conversations. A desire for privacy and avoidance of embarrassment heavily influenced young men's preferences and behaviours in relation to sexual health information seeking. The current available sources of sexual health information for young men are failing to meet their needs. Results identify potential improvements to school-based sexual education and online resources, and describe a need for innovative technology-based sources of sexual health education.

The growing awareness of the environmental significance of fine-grained sediment fluxes through catchment systems continues to underscore the need for reliable information on the principal sources of this material. Source estimates are difficult to obtain using traditional monitoring techniques, but sediment source fingerprinting or tracing procedures, have emerged as a potentially valuable alternative. Despite the rapidly increasing numbers of studies reporting the use of sediment source fingerprinting, several key challenges and uncertainties continue to hamper consensus among the international scientific community on key components of the existing methodological procedures. Accordingly, this contribution reviews and presents recent developments for several key aspects of fingerprinting, namely: sediment source classification, catchment source and target sediment sampling, tracer selection, grain size issues, tracer conservatism, source apportionment modelling, and assessment of source predictions using artificial mixtures. Finally, a decision-tree representing the current state of knowledge is presented, to guide end-users in applying the fingerprinting approach. Copyright © 2016 The Authors.

This study examined the influences of information sources on Zika-relevant knowledge and behaviors in US households containing members who are pregnant, intend to become pregnant, or have a higher probability of unintended pregnancy in Zika-affected regions (i.e. respondents who are younger, are black, have less education, are unmarried, and reside in the southern USA). Over 22 000 US adults completed a survey measuring Zika-relevant knowledge and behaviors along with information sources (e.g. discussing Zika with practitioners), general media usage (e.g. TV) and demographic information over 30 weeks. Respondents in the group with (versus without) either pregnancy or intended pregnancy were more likely to use all information sources, which in turn created differences in knowledge and behavior responses. To gauge information sources in US-South respondents with a high probability of having a household member with unintended pregnancy based on demographics, younger, less-educated, unmarried, black respondents had fewer Zika discussion with practitioners than another group. Efforts to increase Zika-related knowledge and protective behaviors should target households with members who are pregnant or intending to become pregnant via practitioners, family and friends. Additional efforts should target information channels to reach younger, less educated, unmarried, black respondents, which are at risk for unintended pregnancy.

Building Capacity for Evidence-Based Practice: Understanding How Licensed Practical Nurses (LPNs) Source Knowledge.

PubMed

Phillips, Leah; Neumeier, Melanie

2018-03-23

In Canada, all nurses are required to engage in evidence-based practice (EBP) as an entry-to-practice competency; however, there is little research that examines Licensed Practical Nurses' (LPNs') information seeking behaviors or preferred sources of knowledge to conduct EBP. Due to the differences in education and roles of LPNs and Registered Nurses (RNs), it is both necessary and important to gain an understanding of how LPNs utilize evidence in their unique nursing practice. The purpose of this study was to investigate how LPNs source knowledge for their nursing practice. A descriptive, cross-sectional survey of LPNs from Alberta, Canada asked participants to rank sources of knowledge that inform their practice. Responses were correlated with age and years of practice. Analysis of variance was used to determine if there were significant mean differences between average scores and place of employment. LPN participants used similar sources of knowledge as RNs. The top source of knowledge for both RNs and LPNs was the information they learn about each individual client and the least utilized sources of knowledge were articles published in nursing, medical, and research journals, tradition, and popular media. This finding is consistent with previous studies on RNs that found nurses do not often access current research evidence to inform their practice. Since relatively few LPNs access nursing and research journals, it is important to tailor EBP education information to the workplace context. Future avenues of research might explore the potential of using in-services and webinars to disseminate information and skills training on EBP to the LPNs, as this was a popular source of practice knowledge. © 2018 The Authors.

Context Family, especially the mother, has the most important role in the education, transformation of information, and health behaviors of girls in order for them to have a healthy transition from the critical stage of puberty, but there are different views in this regard. Objectives Considering the various findings about the source of information about puberty, a meta-analysis study was conducted to investigate the extent of the mother’s role in informing girls about puberty. Data Sources This meta-analysis study was based on English articles published from 2000 to February 2015 in the Scopus, PubMed, and Science direct databases and on Persian articles in the SID, Magiran, and Iran Medex databases with determined key words and their MeSH equivalent. Study Selection Quantitative cross-sectional articles were extracted by two independent researchers and finally 46 articles were selected based on inclusion criteria. STROBE list were used for evaluation of studies. Data Extraction The percent of mothers as the current and preferred source of gaining information about the process of puberty, menarche, and menstruation from the perspective of adolescent girls was extracted from the articles. The results of studies were analyzed using meta-analysis (random effects model) and the studies’ heterogeneity was analyzed using the I2 calculation index. Variance between studies was analyzed using tau squared (Tau2) and review manager 5 software. Results The results showed that, from the perspective of teenage girls in Iran and other countries, in 56% of cases, the mother was the current source of information about the process of puberty, menarche, and menstruation. The preferred source of information about the process of puberty, menarche, and menstruation was the mother in all studies at 60% (Iran 57%, and other countries 66%). Conclusions According to the findings of this study, it is essential that health professionals and officials of the ministry of health train mothers about the time, trends, and factors affecting the start of puberty using a multi-dimensional approach that involves religious organizations, community groups, and peer groups.

[Digital media as laypeople's source of information about the environment and health].

PubMed

Sassenberg, Kai

2017-06-01

Over the last two decades, the Internet has become the primary source of information. Thanks to the Internet, laypeople have access to information from the health and the environmental sector, which was for a long time available only to experts (e. g. scientific publications, statistics). Information on the Internet varies in quality, as generally anybody can publish online, without any quality control. At the same time, Internet use comes with specific situational characteristics. Given that the amount of information is nearly unlimited and that this information is easily available via search engines, users are not restricted to one or just a few texts, but can choose between multiple sources depending on their motivation and interest. Together with the heterogeneity of the sources, this provides the basis for a strong impact of motivation on the process and the outcomes of information acquisition online. Based on empirical research in the domain of Internet searching in the health sector, the current article discusses the impact of the use of digital media in the context of environmental medicine. Research has led to four conclusions: (1) Users are not sufficiently sensitive to the quality of information. (2) Information supporting their own opinion is preferably processed. (3) Users who feel threatened focus on positive information. (4) Vigilant users focus on negative information, which might result in cyberchrondria. The implications of these effects for the use of digital media in the sector of environmental medicine are discussed.

Passing Decisions in Football: Introducing an Empirical Approach to Estimating the Effects of Perceptual Information and Associative Knowledge.

2018-01-01

The importance of various information sources in decision-making in interactive team sports is debated. While some highlight the role of the perceptual information provided by the current game context, others point to the role of knowledge-based information that athletes have regarding their team environment. Recently, an integrative perspective considering the simultaneous involvement of both of these information sources in decision-making in interactive team sports has been presented. In a theoretical example concerning passing decisions, the simultaneous involvement of perceptual and knowledge-based information has been illustrated. However, no precast method of determining the contribution of these two information sources empirically has been provided. The aim of this article is to bridge this gap and present a statistical approach to estimating the effects of perceptual information and associative knowledge on passing decisions. To this end, a sample dataset of scenario-based passing decisions is analyzed. This article shows how the effects of perceivable team positionings and athletes' knowledge about their fellow team members on passing decisions can be estimated. Ways of transfering this approach to real-world situations and implications for future research using more representative designs are presented.

2014-01-01

Identifying inter-area communication in terms of the hierarchical organization of functional brain areas is of considerable interest in human neuroimaging. Previous studies have suggested that the direction of magneto- and electroencephalography (MEG, EEG) source currents depends on the layer-specific input patterns into a cortical area. We examined the direction in MEG source currents in a visual object recognition experiment in which there were specific expectations of activation in the fusiform region being driven by either feedforward or feedback inputs. The source for the early non-specific visual evoked response, presumably corresponding to feedforward driven activity, pointed outward, i.e., away from the white matter. In contrast, the source for the later, object-recognition related signals, expected to be driven by feedback inputs, pointed inward, toward the white matter. Associating specific features of the MEG/EEG source waveforms to feedforward and feedback inputs could provide unique information about the activation patterns within hierarchically organized cortical areas.

Mueller, Charles; Briggs, Richard; Wesson, Robert L.; Petersen, Mark D.

2015-01-01

The U.S. Geological Survey makes probabilistic seismic hazard maps and engineering design maps for building codes, emergency planning, risk management, and many other applications. The methodology considers all known earthquake sources with their associated magnitude and rate distributions. Specific faults can be modeled if slip-rate or recurrence information is available. Otherwise, areal sources are developed from earthquake catalogs or GPS data. Sources are combined with ground-motion estimates to compute the hazard. The current maps for Alaska were developed in 2007, and included modeled sources for the Alaska-Aleutian megathrust, a few crustal faults, and areal seismicity sources. The megathrust was modeled as a segmented dipping plane with segmentation largely derived from the slip patches of past earthquakes. Some megathrust deformation is aseismic, so recurrence was estimated from seismic history rather than plate rates. Crustal faults included the Fairweather-Queen Charlotte system, the Denali–Totschunda system, the Castle Mountain fault, two faults on Kodiak Island, and the Transition fault, with recurrence estimated from geologic data. Areal seismicity sources were developed for Benioff-zone earthquakes and for crustal earthquakes not associated with modeled faults. We review the current state of knowledge in Alaska from a seismic-hazard perspective, in anticipation of future updates of the maps. Updated source models will consider revised seismicity catalogs, new information on crustal faults, new GPS data, and new thinking on megathrust recurrence, segmentation, and geometry. Revised ground-motion models will provide up-to-date shaking estimates for crustal earthquakes and subduction earthquakes in Alaska.

A review of Soviet plasma engine development

NASA Technical Reports Server (NTRS)

Barnett, John W.

1990-01-01

The Soviet Union has maintained a substantial and successful electric propulsion research and development effort since the 1950s; however, American researchers are generally unfamiliar with the Soviet accomplishments. Sources of information about Soviet electric propulsion research are noted. The development of plasma engines, a subset of the electric propulsion effort, is reviewed using numerous Soviet sources. The operational principles and status of several engines of the closed electron drift and high-current types are discussed. With recognition of the limited knowledge of the current Soviet program, the Soviet and American programs are compared, revealing some differences in program formulation and emphasis.

How U.S. adults find out about electronic cigarettes: implications for public health messages.

PubMed

Pepper, Jessica K; Emery, Sherry L; Ribisl, Kurt M; Brewer, Noel T

2014-08-01

Electronic cigarettes (e-cigarettes) are battery-powered nicotine delivery systems that have become increasingly popular in the United States. We sought to understand how U.S. adults hear about e-cigarettes. A national sample of 17,522 U.S. adults (≥ 18 years old) completed an online survey in March 2013 assessing their awareness of and sources of information about e-cigarettes. Most respondents (86%) had heard of e-cigarettes. Current and former smokers were more likely to be aware of e-cigarettes than non-smokers. Males, younger adults, non-Hispanic Whites, and those with higher education were also more likely to have heard of e-cigarettes. The most commonly reported sources of information were another person, ads on television, and seeing e-cigarettes being sold, although the relative frequency of these sources differed for current, former, and never-smokers. Former and current smokers were more likely to have heard about e-cigarettes from e-cigarette users than were never-smokers. Adults age 30 years or younger were more likely than adults older than 30 years to have heard about e-cigarettes online. Nearly all U.S. adults had heard of e-cigarettes in 2013. By focusing on the most common channels of information, public health campaigns can more efficiently communicate information about e-cigarette safety and consider necessary regulations should companies use these channels for marketing that targets youth, non-tobacco users, and other at-risk groups. © The Author 2014.

aCGH-MAS: Analysis of aCGH by means of Multiagent System

PubMed Central

Benito, Rocío; Bajo, Javier; Rodríguez, Ana Eugenia; Abáigar, María

2015-01-01

There are currently different techniques, such as CGH arrays, to study genetic variations in patients. CGH arrays analyze gains and losses in different regions in the chromosome. Regions with gains or losses in pathologies are important for selecting relevant genes or CNVs (copy-number variations) associated with the variations detected within chromosomes. Information corresponding to mutations, genes, proteins, variations, CNVs, and diseases can be found in different databases and it would be of interest to incorporate information of different sources to extract relevant information. This work proposes a multiagent system to manage the information of aCGH arrays, with the aim of providing an intuitive and extensible system to analyze and interpret the results. The agent roles integrate statistical techniques to select relevant variations and visualization techniques for the interpretation of the final results and to extract relevant information from different sources of information by applying a CBR system.

ABSTRACT Little is known about the current health status of US metal and nonmetal (MNM) miners, in part because no health surveillance systems exist for this population. The National Institute for Occupational Safety and Health (NIOSH) is developing a program to characterize burden of disease among MNM miners. This report discusses current knowledge and potential data sources of MNM miner health. Recent national surveys were analyzed, and literature specific to MNM miner health status was reviewed. No robust estimates of disease prevalence were identified, and national surveys did not provide information specific to MNM miners. Because substantial gaps exist in the understanding of MNM miners' current health status, NIOSH plans to develop a health surveillance program for this population to guide intervention efforts to reduce occupational and personal risks for chronic illness.

Silva, Luís A Bastião; Campos, Samuel; Costa, Carlos; Oliveira, José Luis

2014-08-01

The growing use of computer systems in medical institutions has been generating a tremendous quantity of data. While these data have a critical role in assisting physicians in the clinical practice, the information that can be extracted goes far beyond this utilization. This article proposes a platform capable of assembling multiple data sources within a medical imaging laboratory, through a network of intelligent sensors. The proposed integration framework follows a SOA hybrid architecture based on an information sensor network, capable of collecting information from several sources in medical imaging laboratories. Currently, the system supports three types of sensors: DICOM repository meta-data, network workflows and examination reports. Each sensor is responsible for converting unstructured information from data sources into a common format that will then be semantically indexed in the framework engine. The platform was deployed in the Cardiology department of a central hospital, allowing identification of processes' characteristics and users' behaviours that were unknown before the utilization of this solution.

Information extraction from full text scientific articles: where are the keywords?

PubMed

Shah, Parantu K; Perez-Iratxeta, Carolina; Bork, Peer; Andrade, Miguel A

2003-05-29

To date, many of the methods for information extraction of biological information from scientific articles are restricted to the abstract of the article. However, full text articles in electronic version, which offer larger sources of data, are currently available. Several questions arise as to whether the effort of scanning full text articles is worthy, or whether the information that can be extracted from the different sections of an article can be relevant. In this work we addressed those questions showing that the keyword content of the different sections of a standard scientific article (abstract, introduction, methods, results, and discussion) is very heterogeneous. Although the abstract contains the best ratio of keywords per total of words, other sections of the article may be a better source of biologically relevant data.

The Value of Heterogeneity for Cost-Effectiveness Subgroup Analysis

PubMed Central

Manca, Andrea; Claxton, Karl; Sculpher, Mark J.

2014-01-01

This article develops a general framework to guide the use of subgroup cost-effectiveness analysis for decision making in a collectively funded health system. In doing so, it addresses 2 key policy questions, namely, the identification and selection of subgroups, while distinguishing 2 sources of potential value associated with heterogeneity. These are 1) the value of revealing the factors associated with heterogeneity in costs and outcomes using existing evidence (static value) and 2) the value of acquiring further subgroup-related evidence to resolve the uncertainty given the current understanding of heterogeneity (dynamic value). Consideration of these 2 sources of value can guide subgroup-specific treatment decisions and inform whether further research should be conducted to resolve uncertainty to explain variability in costs and outcomes. We apply the proposed methods to a cost-effectiveness analysis for the management of patients with acute coronary syndrome. This study presents the expected net benefits under current and perfect information when subgroups are defined based on the use and combination of 6 binary covariates. The results of the case study confirm the theoretical expectations. As more subgroups are considered, the marginal net benefit gains obtained under the current information show diminishing marginal returns, and the expected value of perfect information shows a decreasing trend. We present a suggested algorithm that synthesizes the results to guide policy. PMID:24944196

Dietary fibres are key elements of healthy and balanced diet. The aim of the present study was to explore consumers' knowledge considering fibre, their role in the purchasing decisions, and the cognition of the currently used as well as the possible information sources to encourage the fibre consumption. A questionnaire survey was conducted with 303 respondents. Knowledge about the fibre sources has showed a kind of uncertainty of the respondents, while knowledge about their possible health effects was relatively profound. Internet appeared as a remarkable information source in the topic; however, results pointed out the importance of education, too. Participants more often consuming foodstuffs rich in fibre, women and respondents over 45 years old showed conscious attitudes regarding fibres. Guidelines and education containing authentic information and practical elements are essential, and as a result, consumers' latent knowledge will appear in their conscious food choice decisions.

Effective pollutant emission heights for atmospheric transport modelling based on real-world information.

PubMed

Pregger, Thomas; Friedrich, Rainer

2009-02-01

Emission data needed as input for the operation of atmospheric models should not only be spatially and temporally resolved. Another important feature is the effective emission height which significantly influences modelled concentration values. Unfortunately this information, which is especially relevant for large point sources, is usually not available and simple assumptions are often used in atmospheric models. As a contribution to improve knowledge on emission heights this paper provides typical default values for the driving parameters stack height and flue gas temperature, velocity and flow rate for different industrial sources. The results were derived from an analysis of the probably most comprehensive database of real-world stack information existing in Europe based on German industrial data. A bottom-up calculation of effective emission heights applying equations used for Gaussian dispersion models shows significant differences depending on source and air pollutant and compared to approaches currently used for atmospheric transport modelling.

Optimizing height presentation for aircraft cockpit displays

1997-02-01

This paper describes an experiment conducted to investigate the type of display symbology that most effectively conveys height information to users of head-down plan-view radar displays. The experiment also investigated the use of multiple information sources (redundancy) in the design of such displays. Subjects were presented with eight different height display formats. These formats were constructed from a control, and/or one, two, or three sources of redundant information. The three formats were letter coding, analogue scaling, and toggling (spatially switching the position of the height information from above to below the aircraft symbol). Subjects were required to indicate altitude awareness via a four-key, forced-choice keyboard response. Error scores and response times were taken as performance measures. There were three main findings. First, there was a significant performance advantage when the altitude information was presented above and below the symbol to aid the representation of height information. Second, the analogue scale, a line whose length indicated altitude, proved significantly detrimental to performance. Finally, no relationship was found between the number of redundant information sources employed and performance. The implications for future aircraft and displays are discussed in relation to current aircraft tactical displays and in the context of perceptual psychological theory.

Current sources of publicly available human papillomavirus (HPV) information may not adequately meet the needs of diverse families. This study sought to describe associations between sociodemographic and acculturation factors, and sources of HPV information among diverse parents and caregivers. Community organizations purposively recruited participants from African American, African refugee, Hispanic/Latino, American Indian, and Native Hawaiian and Pacific Islander communities for a 21-item survey (N = 228). Ninenty-three of these participants also participated in ten focus groups conducted in three languages. Descriptive statistics and Fishers' Exact Test for Count Data were produced and triangulated with focus group data to provide additional context. Overall, HPV vaccine awareness and knowledge in the five communities was low. This study found that a greater proportion of lower-acculturated participants had heard of HPV through personal networks (foreign-born = 50 % vs US-born = 30 %, p < 0.05; medium acculturation = 60 % vs high acculturation = 26 %, p = 0.01), while greater proportions of US-born participants reported media sources (49 % vs foreign-born = 29 %, p < 0.05). Across communities, healthcare system sources were described as important and preferred sources of HPV information. Hearing about the HPV vaccine from healthcare settings was significantly associated with increased accuracy in HPV vaccine knowledge (p < 0.05). Communities described a need for more in-depth information about the HPV vaccine, and culturally and linguistically appropriate educational materials. Culturally-competent delivery of HPV information through the healthcare system sources may be important in improving knowledge and acceptability of the HPV vaccine among diverse families.

From disease to desire, pleasure to the pill: A qualitative study of adolescent learning about sexual health and sexuality in Chile.

2015-09-23

Sexual and reproductive rights include access to accurate and appropriate information in order to make informed decisions. In the current age of media globalization and Internet, adolescents are exposed to information about sexual health and sexuality from a myriad of sources. The objective of this study was to explore sources of information and adolescent learning about sexual health and sexuality in Santiago, Chile. Data collection included four focus group discussions with a total of 24 adolescents 18-19 years old, 20 semi-structured interviews with adolescents 16-19 years old, and seven interviews with key informants working with adolescents. Audio recordings were transcribed verbatim and analysed using content analysis. The primary sources of sexual health and sexuality information were parents, teachers and friends, whilst secondary sources included health professionals for females and Internet for males. Information provided by the trusted sources of parents, teachers and health professionals tended to focus on biological aspects of sexuality, particularly pregnancy and sexually transmitted infections. Limited emphasis was placed on topics such as love, attraction, pleasure, relationships, abstinence and sexual violence. Information focused primarily on heterosexual relations and reproduction. Adolescents learnt about relationships and sexual acts through friends, partners and, for many males, pornography. Findings indicate a lack of available information on partner communication, setting personal limits, and contraception, including morally neutral and medically correct information about emergency contraception. This study highlights numerous gaps between adolescent information needs and information provided by parents, teachers and health professionals. The priority these trusted sources place on providing biological information overshadows learning about emotional and relational aspects of sexuality. This biological rationalization of adolescent sexual behaviour neglects the way gender inequality, peer-pressure, coercion, media eroticization and religion influence adolescent sexual decision-making. The heteronormativity of information excludes other sexual orientations and disregards the diverse spectrum of human sexual behaviours. Finally, the limited provision of practical information hinders development of skills necessary for ensuring safe, consensual and pleasurable sexual relations. Trusted adults are encouraged to engage adolescents in critical reflection on a broad range of sexuality topics, dispelling myths, and building knowledge and skills necessary to make informed decisions.

Encoding and retrieval processes involved in the access of source information in the absence of item memory.

PubMed

Ball, B Hunter; DeWitt, Michael R; Knight, Justin B; Hicks, Jason L

2014-09-01

The current study sought to examine the relative contributions of encoding and retrieval processes in accessing contextual information in the absence of item memory using an extralist cuing procedure in which the retrieval cues used to query memory for contextual information were related to the target item but never actually studied. In Experiments 1 and 2, participants studied 1 category member (e.g., onion) from a variety of different categories and at test were presented with an unstudied category label (e.g., vegetable) to probe memory for item and source information. In Experiments 3 and 4, 1 member of unidirectional (e.g., credit or card) or bidirectional (e.g., salt or pepper) associates was studied, whereas the other unstudied member served as a test probe. When recall failed, source information was accessible only when items were processed deeply during encoding (Experiments 1 and 2) and when there was strong forward associative strength between the retrieval cue and target (Experiments 3 and 4). These findings suggest that a retrieval probe diagnostic of semantically related item information reinstantiates information bound in memory during encoding that results in reactivation of associated contextual information, contingent upon sufficient learning of the item itself and the association between the item and its context information.

Footrot and interdigital dermatitis in sheep: farmer satisfaction with current management, their ideal management and sources used to adopt new strategies.

PubMed

Wassink, G J; George, T R N; Kaler, J; Green, L E

2010-08-01

The aims of this research were to identify management practices that sheep farmers currently use to treat and prevent footrot in sheep and whether they consider that these are successful management tools and to find out how sheep farmers would ideally like to manage footrot in their flock. Over 90% of lameness in sheep in the UK is caused by Dichelobacter nodosus, which presents clinically as interdigital dermatitis (ID) alone or with separation of hoof horn (FR). A questionnaire was sent to 265 farmers to investigate their current management and their satisfaction with current management of the spectrum of clinical presentations of footrot. Farmers were also asked their ideal management of footrot and their interest in, and sources of information for, change. Approximately 160 farmers responded. Farmers satisfied with current management reported a prevalence of lameness < or = 5%. These farmers caught and treated lame sheep within 3 days of first seeing them lame, and treated sheep with FR and ID with parenteral antibacterials. Farmers dissatisfied with their management reported a prevalence of lameness >5%. These farmers practised routine foot trimming, footbathing and vaccination against footrot. Whilst 89% of farmers said they were satisfied with their management of FR over 34% were interested in changing management. Farmers identified veterinarians as the most influential source for new information. Farmers reported that ideally they would control FR by culling/isolating lame sheep, sourcing replacements from non-lame parents, trimming feet less, using antibacterial treatments less and using vaccination more. Footbathing was a commonly used management that was linked with dissatisfaction and that also was listed highly as an ideal management. Consequently, some of the ideal managements are in agreement with our understanding of disease control (culling and isolation, sourcing healthy replacements) but others are in contrast with our current knowledge of management and farmers self-reporting of satisfaction of management of footrot (less use of antibacterial treatment, more footbathing and vaccination). One explanation for this is the theory of cognitive dissonance where belief follows behaviour, i.e. farmers report that they believe an ideal which is what they are currently doing, even if the management is sub-optimal.

Bayesian Model Development for Analysis of Open Source Information to Support the Assessment of Nuclear Programs

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

Gastelum, Zoe N.; Whitney, Paul D.; White, Amanda M.

2013-07-15

Pacific Northwest National Laboratory has spent several years researching, developing, and validating large Bayesian network models to support integration of open source data sets for nuclear proliferation research. Our current work focuses on generating a set of interrelated models for multi-source assessment of nuclear programs, as opposed to a single comprehensive model. By using this approach, we can break down the models to cover logical sub-problems that can utilize different expertise and data sources. This approach allows researchers to utilize the models individually or in combination to detect and characterize a nuclear program and identify data gaps. The models operatemore » at various levels of granularity, covering a combination of state-level assessments with more detailed models of site or facility characteristics. This paper will describe the current open source-driven, nuclear nonproliferation models under development, the pros and cons of the analytical approach, and areas for additional research.« less

Male perceptions on female sterilization: a community-based study in rural Central India.

PubMed

Char, Arundhati; Saavala, Minna; Kulmala, Teija

2009-09-01

Use of modern contraceptive methods has increased fourfold in India since the 1970s, characterized by a predominance of female sterilization. There has been considerable investigation about women's choice of female sterilization, but little from the male perspective. Seven focus group discussions were conducted among 58 men currently married to women aged 15-45, followed by a cross-sectional survey among 793 men currently married to same-aged women. Bivariate analysis was used for the survey data, and content analysis was used for the qualitative data. Men's primary source of reproductive health information was mass media, although they expressed interest in getting information through discussion with knowledgeable sources. Men understood family planning and contraception to be two separate issues: Men viewed "family planning" as synonymous with female sterilization, whereas they saw "contraception" as referring to spacing methods, knowledge of which was limited. Thirty-four percent of men reported that their wives had been sterilized; 79% of men who did not rely on any permanent method said they wanted their wives to be sterilized. In focus group discussions, most men reported themselves as their family's sole decision maker about reproductive health; however, only one-third of survey respondents did so. Men are interested in acquiring family planning information, but lack knowledge about available information sources, which hampers their ability to make informed family planning choices. Family planning service providers and program planners need to be aware of males' knowledge and perceptions pertaining to family planning, and make appropriate modifications to communication strategies.

From hypothetical scenario to tragic reality: A salutary lesson in risk communication and the Victorian 2009 bushfires.

To investigate the ways that the risk of a bushfire emergency and communication strategies are perceived by different community segments. A brief questionnaire preceded focus group discussion of a bushfire scenario with four communications from different sources. Groups were recruited to represent different community segments within a bushfire-prone peri-urban Shire in Victoria. Four groups (28 participants) were recruited. Bushfire experience was highest in the over 40-year-olds, who would use a variety of information sources, preferred to receive information from trusted local sources, such as emergency services and the council, and were more likely to be a member of a local organisation than the under 40s. Younger people used television, local papers, and friends, family and neighbours as information sources. Young parents felt disempowered through lack of local knowledge, and trusted government departments less than older residents. All wanted clear, current, specific local information about ground conditions and actions to be taken during a fire outbreak. Knowledge of and preparedness for bushfire is unequally spread throughout a bushfire community. There is a need in public health risk and emergency situations to focus on community development, information and consultation. © 2010 The Authors.

WE-E-18C-01: Multi-Energy CT: Current Status and Recent Innovations

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

Pelc, N; McCollough, C; Yu, L

2014-06-15

Conventional computed tomography (CT) uses a single polychromatic x-ray spectrum and energy integrating detectors, and produces images whose contrast depends on the effective attenuation coefficient of the broad spectrum beam. This can introduce errors from beam hardening and does not produce the optimal contrast-to-noise ratio. In addition, multiple materials can have the same effective attenuation coefficient, causing different materials to be indistinguishable in conventional CT images. If transmission measurements at two or more energies are obtained, even with polychromatic beams, more specific information about the object can be obtained. If the object does not contain materials with k-edges in themore » spectrum, the x-ray attenuation can be well-approximated by a linear combination of two processes (photoelectric absorption and Compton scattering) or, equivalently, two basis materials. For such cases, two spectral measurements suffice, although additional measurements can provide higher precision. If K-edge materials are present, additional spectral measurements can allow these materials to be isolated. Current commercial implementations use varied approaches, including two sources operating a different kVp, one source whose kVp is rapidly switched in a single scan, and a dual layer detector that can provide spectral information in every reading. Processing of the spectral information can be performed in the raw data domain or in the image domain. The process of calculating the amount of the two basis functions implicitly corrects for beam hardening and therefore can lead to improvements in quantitative accuracy. Information can be extracted to provide material specific information beyond that of conventional CT. This additional information has been shown to be important in several clinical applications, and can also lead to more efficient clinical protocols. Recent innovations in x-ray sources, detectors, and systems have made multi-energy CT much more practical and improved its performance. In addition, this is a very active area of research and further improvements are expected through further technological improvements.

During the past years, the advances in high-throughput technologies have produced an unprecedented growth in the number and size of repositories and databases storing relevant biological data. Today, there is more biological information than ever but, unfortunately, the current status of many of these repositories is far from being optimal. Some of the most common problems are that the information is spread out in many small databases; frequently there are different standards among repositories and some databases are no longer supported or they contain too specific and unconnected information. In addition, data size is increasingly becoming an obstacle when accessing or storing biological data. All these issues make very difficult to extract and integrate information from different sources, to analyze experiments or to access and query this information in a programmatic way. CellBase provides a solution to the growing necessity of integration by easing the access to biological data. CellBase implements a set of RESTful web services that query a centralized database containing the most relevant biological data sources. The database is hosted in our servers and is regularly updated. CellBase documentation can be found at http://docs.bioinfo.cipf.es/projects/cellbase.

Open Source Clinical NLP - More than Any Single System.

2014-01-01

The number of Natural Language Processing (NLP) tools and systems for processing clinical free-text has grown as interest and processing capability have surged. Unfortunately any two systems typically cannot simply interoperate, even when both are built upon a framework designed to facilitate the creation of pluggable components. We present two ongoing activities promoting open source clinical NLP. The Open Health Natural Language Processing (OHNLP) Consortium was originally founded to foster a collaborative community around clinical NLP, releasing UIMA-based open source software. OHNLP's mission currently includes maintaining a catalog of clinical NLP software and providing interfaces to simplify the interaction of NLP systems. Meanwhile, Apache cTAKES aims to integrate best-of-breed annotators, providing a world-class NLP system for accessing clinical information within free-text. These two activities are complementary. OHNLP promotes open source clinical NLP activities in the research community and Apache cTAKES bridges research to the health information technology (HIT) practice.

The purpose of this study was to investigate the sources, both print and electronic formats, which Australian nurse practitioners (NPs) currently use to obtain information regarding quality use of medicines (QUM). An additional aim was to document NPs' preferences for continuing education in relation to QUM. A national electronic survey of Australian NPs was conducted in 2007 and again in 2010. Eighty percent of respondents accessed information on QUM from professional literature, which may include scholarly journal articles, reports, and independent publications. There was a decrease in the percentage of respondents who obtained information from drug industry representatives. NPs prefer to receive medicines information in an electronic form, rather than a paper-based version, and over the time period more NPs are utilizing electronic sources rather than paper. These findings provide important insights into medical information products for the developers who may be able to use these results to ensure that their products meet the needs of NP clinicians. Additionally, the finding that NPs prefer to receive their continuing information related to medicines in electronic format, but also highly value conference proceedings, may help to inform future planning of NP education needs in relation to QUM. ©2014 American Association of Nurse Practitioners.

Falcone, James A.; Homer, Collin G.

2012-01-01

Characterization of urban land uses is essential for many applications. However, differentiating among thematically-detailed urban land uses (residential, commercial, industrial, institutional, recreational, etc.) over broad areas is challenging, in part because image-based solutions are not ideal for establishing the contextual basis for identifying economic function and use. At present no current United States national-scale mapping exists for urban land uses similar to the classical Anderson Level II classification. This paper describes a product that maps urban land uses, and is linked to and corresponds with the National Land Cover Database (NLCD) 2006. In this product, NLCD urban pixels, in addition to their current imperviousness intensity classification, are assigned one of nine urban use classes based on information drawn from multiple data sources. These sources include detailed infrastructure information, population characteristics, and historical land use. The result is a method for creating a 30 m national-scale grid providing thematically-detailed urban land use information which complements the NLCD. Initial results for 10 major metropolitan areas are provided as an on-line link. Accuracy assessment of initial products yielded an overall accuracy of 81.6 percent.

Background Influenza outbreaks pose major challenges to public health around the world, leading to thousands of deaths a year in the United States alone. Accurate systems that track influenza activity at the city level are necessary to provide actionable information that can be used for clinical, hospital, and community outbreak preparation. Objective Although Internet-based real-time data sources such as Google searches and tweets have been successfully used to produce influenza activity estimates ahead of traditional health care–based systems at national and state levels, influenza tracking and forecasting at finer spatial resolutions, such as the city level, remain an open question. Our study aimed to present a precise, near real-time methodology capable of producing influenza estimates ahead of those collected and published by the Boston Public Health Commission (BPHC) for the Boston metropolitan area. This approach has great potential to be extended to other cities with access to similar data sources. Methods We first tested the ability of Google searches, Twitter posts, electronic health records, and a crowd-sourced influenza reporting system to detect influenza activity in the Boston metropolis separately. We then adapted a multivariate dynamic regression method named ARGO (autoregression with general online information), designed for tracking influenza at the national level, and showed that it effectively uses the above data sources to monitor and forecast influenza at the city level 1 week ahead of the current date. Finally, we presented an ensemble-based approach capable of combining information from models based on multiple data sources to more robustly nowcast as well as forecast influenza activity in the Boston metropolitan area. The performances of our models were evaluated in an out-of-sample fashion over 4 influenza seasons within 2012-2016, as well as a holdout validation period from 2016 to 2017. Results Our ensemble-based methods incorporating information from diverse models based on multiple data sources, including ARGO, produced the most robust and accurate results. The observed Pearson correlations between our out-of-sample flu activity estimates and those historically reported by the BPHC were 0.98 in nowcasting influenza and 0.94 in forecasting influenza 1 week ahead of the current date. Conclusions We show that information from Internet-based data sources, when combined using an informed, robust methodology, can be effectively used as early indicators of influenza activity at fine geographic resolutions.

Bahamians and Climate Change: An Analysis of Risk Perception and Climate Change Literacy

Neely, R.; Owens, M. A.

2011-12-01

The Commonwealth of the Bahamas is forecasted to be adversely impacted by the effects of climate change. This presentation will present the results of an assessment of the risk perception toward climate change and climate change literacy among Bahamians. 499 Bahamians from the health care and hospitality industries participated in surveys and/or focus groups and three (3) areas of climate change literacy (attitude, behavior and knowledge) were analyzed as well as risk perception. In general, 1) Bahamians demonstrated an elementary understanding of the underlying causes of climate change, 2) possessed positive attitudes toward adopting new climate change policies, and 3) are already adjusting their behaviors in light of the current predictions. This research also resulted in the development of a model of the relationships between the climate literacy subscales (attitude, behavior and knowledge) and risk perception. This study also examined information sources and their impacts on climate change literacy. As the source of information is important in assessing the quality of the information, participants also identified the source(s) of most of their climate change information. The TV news was cited as the most common source for climate change information among Bahamians. As there is limited active research generating specific climate change information in the Bahamas, all the information Bahamians receive as it pertains to climate change is generated abroad. As a result, Bahamians must decipher through to make sense of it on an individual level. From the focus groups, many of the participants have been able to view possible changes through a cultural lens and are willing to make adjustments to maintain the uniqueness and viability of the Bahamas and to preserve it for generations. Continued study of Bahamians' climate change literacy will inform adaption and mitigation policy as well as individual action.

The Saccharomyces Genome Database (SGD; http://www.yeastgenome.org/) collects and organizes biological information about the chromosomal features and gene products of the budding yeast Saccharomyces cerevisiae. Although published data from traditional experimental methods are the primary sources of evidence supporting Gene Ontology (GO) annotations for a gene product, high-throughput experiments and computational predictions can also provide valuable insights in the absence of an extensive body of literature. Therefore, GO annotations available at SGD now include high-throughput data as well as computational predictions provided by the GO Annotation Project (GOA UniProt; http://www.ebi.ac.uk/GOA/). Because the annotation method used to assign GO annotations varies by data source, GO resources at SGD have been modified to distinguish data sources and annotation methods. In addition to providing information for genes that have not been experimentally characterized, GO annotations from independent sources can be compared to those made by SGD to help keep the literature-based GO annotations current.

Design and Analysis Tools for Concurrent Blackboard Systems

NASA Technical Reports Server (NTRS)

McManus, John W.

1991-01-01

A blackboard system consists of a set of knowledge sources, a blackboard data structure, and a control strategy used to activate the knowledge sources. The blackboard model of problem solving is best described by Dr. H. Penny Nii of the Stanford University AI Laboratory: "A Blackboard System can be viewed as a collection of intelligent agents who are gathered around a blackboard, looking at pieces of information written on it, thinking about the current state of the solution, and writing their conclusions on the blackboard as they generate them. " The blackboard is a centralized global data structure, often partitioned in a hierarchical manner, used to represent the problem domain. The blackboard is also used to allow inter-knowledge source communication and acts as a shared memory visible to all of the knowledge sources. A knowledge source is a highly specialized, highly independent process that takes inputs from the blackboard data structure, performs a computation, and places the results of the computation in the blackboard data structure. This design allows for an opportunistic control strategy. The opportunistic problem-solving technique allows a knowledge source to contribute towards the solution of the current problem without knowing which of the other knowledge sources will use the information. The use of opportunistic problem-solving allows the data transfers on the blackboard to determine which processes are active at a given time. Designing and developing blackboard systems is a difficult process. The designer is trying to balance several conflicting goals and achieve a high degree of concurrent knowledge source execution while maintaining both knowledge and semantic consistency on the blackboard. Blackboard systems have not attained their apparent potential because there are no established tools or methods to guide in their construction or analyze their performance.

IntroductionInformation concerning the availability, use, and quality of water in Iberia Parish, Louisiana, is critical for proper water-resource management. This fact sheet summarizes the availability, past and current use, use trends, and water quality from groundwater and surface-water sources in the parish for water managers, parish residents, and others to assist in stewardship of this vital resource. Previously published reports and data stored in the U.S. Geological Survey’s National Water Information System are the primary sources of the information presented here.In 2010, about 31.24 million gallons per day (Mgal/d) of water were withdrawn in Iberia Parish, Louisiana, including about 23.13 Mgal/d from groundwater sources and 8.11 Mgal/d from surface-water sources. Withdrawals for public supply and industrial use each accounted for about 32 percent of the total water withdrawn. Other water-use categories included rural domestic, livestock, rice irrigation, general irrigation, and aquaculture. Water-use data collected at 5-year intervals from 1960 to 2010 indicated that water withdrawals in Iberia Parish peaked at about 58.57 Mgal/d in 1975.

A Source-based Measurement Database for Occupational Exposure Assessment of Electromagnetic Fields in the INTEROCC Study: A Literature Review Approach

Introduction: To date, occupational exposure assessment of electromagnetic fields (EMF) has relied on occupation-based measurements and exposure estimates. However, misclassification due to between-worker variability remains an unsolved challenge. A source-based approach, supported by detailed subject data on determinants of exposure, may allow for a more individualized exposure assessment. Detailed information on the use of occupational sources of exposure to EMF was collected as part of the INTERPHONE-INTEROCC study. To support a source-based exposure assessment effort within this study, this work aimed to construct a measurement database for the occupational sources of EMF exposure identified, assembling available measurements from the scientific literature. Methods: First, a comprehensive literature search was performed for published and unpublished documents containing exposure measurements for the EMF sources identified, a priori as well as from answers of study subjects. Then, the measurements identified were assessed for quality and relevance to the study objectives. Finally, the measurements selected and complementary information were compiled into an Occupational Exposure Measurement Database (OEMD). Results: Currently, the OEMD contains 1624 sets of measurements (>3000 entries) for 285 sources of EMF exposure, organized by frequency band (0 Hz to 300 GHz) and dosimetry type. Ninety-five documents were selected from the literature (almost 35% of them are unpublished technical reports), containing measurements which were considered informative and valid for our purpose. Measurement data and complementary information collected from these documents came from 16 different countries and cover the time period between 1974 and 2013. Conclusion: We have constructed a database with measurements and complementary information for the most common sources of exposure to EMF in the workplace, based on the responses to the INTERPHONE-INTEROCC study questionnaire. This database covers the entire EMF frequency range and represents the most comprehensive resource of information on occupational EMF exposure. It is available at www.crealradiation.com/index.php/en/databases. PMID:26493616

Disambiguating past events: Accurate source memory for time and context depends on different retrieval processes.

PubMed

Persson, Bjorn M; Ainge, James A; O'Connor, Akira R

2016-07-01

Current animal models of episodic memory are usually based on demonstrating integrated memory for what happened, where it happened, and when an event took place. These models aim to capture the testable features of the definition of human episodic memory which stresses the temporal component of the memory as a unique piece of source information that allows us to disambiguate one memory from another. Recently though, it has been suggested that a more accurate model of human episodic memory would include contextual rather than temporal source information, as humans' memory for time is relatively poor. Here, two experiments were carried out investigating human memory for temporal and contextual source information, along with the underlying dual process retrieval processes, using an immersive virtual environment paired with a 'Remember-Know' memory task. Experiment 1 (n=28) showed that contextual information could only be retrieved accurately using recollection, while temporal information could be retrieved using either recollection or familiarity. Experiment 2 (n=24), which used a more difficult task, resulting in reduced item recognition rates and therefore less potential for contamination by ceiling effects, replicated the pattern of results from Experiment 1. Dual process theory predicts that it should only be possible to retrieve source context from an event using recollection, and our results are consistent with this prediction. That temporal information can be retrieved using familiarity alone suggests that it may be incorrect to view temporal context as analogous to other typically used source contexts. This latter finding supports the alternative proposal that time since presentation may simply be reflected in the strength of memory trace at retrieval - a measure ideally suited to trace strength interrogation using familiarity, as is typically conceptualised within the dual process framework.

Review of terahertz semiconductor sources

NASA Astrophysics Data System (ADS)

Wei, Feng

2012-03-01

Terahertz (THz) technology can be used in information science, biology, medicine, astronomy, and environmental science. THz sources are the key devices in THz applications. The author gives a brief review of THz semiconductor sources, such as GaAs1-xNx Gunn-like diodes, quantum wells (QWs) negative-effective-mass (NEM) THz oscillators, and the THz quantum cascade lasers (QCLs). THz current self-oscillation in doped GaAs1-xNx diodes driven by a DC electric field was investigated. The current self-oscillation is associated with the negative differential velocity effect in the highly nonparabolic conduction band of this unique material system. The current self-oscillations and spatiotemporal current patterns in QW NEM p+pp+ diodes was studied by considering scattering contributions from impurities, acoustic phonons, and optic phonons. It is indicated that both the applied bias and the doping concentration strongly influence the patterns and self-oscillating frequencies. The NEM p+pp+ diode may be used as an electrically tunable THz source. Meanwhile, by using the Monte Carlo method, the device parameters of resonant-phonon THz QCLs were optimized. The results show that the calculated gain is more sensitive to the injection barrier width, the doping concentration, and the phonon extraction level separation, which is consistent with the experiments.

An evaluation of the content and quality of tinnitus information on websites preferred by General Practitioners

PubMed Central

2012-01-01

Background Tinnitus is a prevalent and complex medical complaint often co-morbid with stress, anxiety, insomnia, depression, and cognitive or communication difficulties. Its chronicity places a major burden on primary and secondary healthcare services. In our recent national survey of General Practitioners (GPs) from across England, many reported that their awareness of tinnitus was limited and as a result were dissatisfied with the service they currently provide. GPs identified 10 online sources of information they currently use in clinical practice, but welcomed further concise and accurate information on tinnitus assessment and management.

Tinnitus is a prevalent and complex medical complaint often co-morbid with stress, anxiety, insomnia, depression, and cognitive or communication difficulties. Its chronicity places a major burden on primary and secondary healthcare services. In our recent national survey of General Practitioners (GPs) from across England, many reported that their awareness of tinnitus was limited and as a result were dissatisfied with the service they currently provide. GPs identified 10 online sources of information they currently use in clinical practice, but welcomed further concise and accurate information on tinnitus assessment and management.

Medial prefrontal cortex supports source memory accuracy for self-referenced items.

PubMed

Leshikar, Eric D; Duarte, Audrey

2012-01-01

Previous behavioral work suggests that processing information in relation to the self enhances subsequent item recognition. Neuroimaging evidence further suggests that regions along the cortical midline, particularly those of the medial prefrontal cortex (PFC), underlie this benefit. There has been little work to date, however, on the effects of self-referential encoding on source memory accuracy or whether the medial PFC might contribute to source memory for self-referenced materials. In the current study, we used fMRI to measure neural activity while participants studied and subsequently retrieved pictures of common objects superimposed on one of two background scenes (sources) under either self-reference or self-external encoding instructions. Both item recognition and source recognition were better for objects encoded self-referentially than self-externally. Neural activity predictive of source accuracy was observed in the medial PFC (Brodmann area 10) at the time of study for self-referentially but not self-externally encoded objects. The results of this experiment suggest that processing information in relation to the self leads to a mnemonic benefit for source level features, and that activity in the medial PFC contributes to this source memory benefit. This evidence expands the purported role that the medial PFC plays in self-referencing.

Data expansion: the potential of grey literature for understanding floods

NASA Astrophysics Data System (ADS)

Uhlemann, S.; Bertelmann, R.; Merz, B.

2012-09-01

Sophisticated methods have been developed and become standard in analysing floods as well as for assessing the flood risk. However, increasingly critique of the current standards and scientific practice can be found both in the flood hydrology community as well as in the risk community who argue that the considerable amount of information already available on natural disasters has not been adequately deployed and brought to effective use. We describe this phenomenon as a failure to synthesize knowledge that results from barriers and ignorance in awareness, use and management of the entire spectrum of relevant content, that is, data, information and knowledge. In this paper we argue that the scientific community in flood risk research ignores event specific analysis and documentations as another source of data. We present results from a systematic search that includes an intensive study on sources and ways of information dissemination of flood relevant publications. We obtain 183 documents that contain information on the sources, pathways, receptors and/or consequences for any of the 40 strongest trans-basin floods in Germany in the period 1952-2002. This study therefore provides the most comprehensive meta-data collection of flood documentations for the considered geographical space and period. 87.5% of all events have been documented and especially the most severe floods have received extensive coverage. Only 30% of the material has been produced in the scientific/academic environment and the majority of all documents (about 80%) can be considered grey literature. Therefore, ignoring grey sources in flood research also means ignoring the largest part of knowledge available on single flood events (in Germany). Further, the results of this study underpin the rapid changes in information dissemination of flood event literature over the last decade. We discuss the options and obstacles of incorporating this data in the knowledge building process in the light of the current technological developments and international, interdisciplinary debates for data curation.

Deep brain stimulation for obsessive-compulsive disorder: Knowledge and concerns among psychiatrists, psychotherapists and patients.

Deep brain stimulation (DBS) is under investigation for severe obsessive-compulsive disorder (OCD) resistant to other therapies. The number of implants worldwide is slowly increasing. Therefore, it is of importance to explore knowledge and concerns of this novel treatment among patients and their psychiatric healthcare contacts. This information is relevant for scientific professionals working with clinical studies for DBS for this indication. Especially, for future study designs and the creation of information targeting healthcare professionals and patients. The aim of this study was to explore the knowledge and concerns toward DBS among patients with OCD, psychiatrists, and cognitive behavioral therapists. The study was conducted through web-based surveys for the aimed target groups -psychiatrist, patients, and cognitive behavioral therapists. The surveys contained questions regarding previous knowledge of DBS, source of knowledge, attitudes, and concerns towards the therapy. The main source of information was from scientific sources among psychiatrists and psychotherapists. The patient's main source of information was the media. Common concerns among the groups included complications from surgery, anesthesia, stimulation side effects, and the novelty of the treatment. Specific concerns for the groups included; personality changes mentioned by patients and psychotherapists, and ethical concerns among psychiatrists. There are challenges for DBS in OCD as identified by the participants of this study; source and quality of information, efficacy, potential adverse effects, and eligibility. In all of which the current evidence base still is limited. A broad research agenda is needed for studies going forward.

Vaccine Hesitancy and Online Information: The Influence of Digital Networks.

This article analyzes the digital childhood vaccination information network for vaccine-hesitant parents. The goal of this study was to explore the structure and influence of vaccine-hesitant content online by generating a database and network analysis of vaccine-relevant content. We used Media Cloud, a searchable big-data platform of over 550 million stories from 50,000 media sources, for quantitative and qualitative study of an online media sample based on keyword selection. We generated a hyperlink network map and measured indegree centrality of the sources and vaccine sentiment for a random sample of 450 stories. 28,122 publications from 4,817 sources met inclusion criteria. Clustered communities formed based on shared hyperlinks; communities tended to link within, not among, each other. The plurality of information was provaccine (46.44%, 95% confidence interval [39.86%, 53.20%]). The most influential sources were in the health community (National Institutes of Health, Centers for Disease Control and Prevention) or mainstream media ( New York Times); some user-generated sources also had strong influence and were provaccine (Wikipedia). The vaccine-hesitant community rarely interacted with provaccine content and simultaneously used primary provaccine content within vaccine-hesitant narratives. The sentiment of the overall conversation was consistent with scientific evidence. These findings demonstrate an online environment where scientific evidence online drives vaccine information outside of the vaccine-hesitant community but is also prominently used and misused within the robust vaccine-hesitant community. Future communication efforts should take current context into account; more information may not prevent vaccine hesitancy.

PhySIC_IST: cleaning source trees to infer more informative supertrees

PubMed Central

Scornavacca, Celine; Berry, Vincent; Lefort, Vincent; Douzery, Emmanuel JP; Ranwez, Vincent

2008-01-01

Background Supertree methods combine phylogenies with overlapping sets of taxa into a larger one. Topological conflicts frequently arise among source trees for methodological or biological reasons, such as long branch attraction, lateral gene transfers, gene duplication/loss or deep gene coalescence. When topological conflicts occur among source trees, liberal methods infer supertrees containing the most frequent alternative, while veto methods infer supertrees not contradicting any source tree, i.e. discard all conflicting resolutions. When the source trees host a significant number of topological conflicts or have a small taxon overlap, supertree methods of both kinds can propose poorly resolved, hence uninformative, supertrees. Results To overcome this problem, we propose to infer non-plenary supertrees, i.e. supertrees that do not necessarily contain all the taxa present in the source trees, discarding those whose position greatly differs among source trees or for which insufficient information is provided. We detail a variant of the PhySIC veto method called PhySIC_IST that can infer non-plenary supertrees. PhySIC_IST aims at inferring supertrees that satisfy the same appealing theoretical properties as with PhySIC, while being as informative as possible under this constraint. The informativeness of a supertree is estimated using a variation of the CIC (Cladistic Information Content) criterion, that takes into account both the presence of multifurcations and the absence of some taxa. Additionally, we propose a statistical preprocessing step called STC (Source Trees Correction) to correct the source trees prior to the supertree inference. STC is a liberal step that removes the parts of each source tree that significantly conflict with other source trees. Combining STC with a veto method allows an explicit trade-off between veto and liberal approaches, tuned by a single parameter. Performing large-scale simulations, we observe that STC+PhySIC_IST infers much more informative supertrees than PhySIC, while preserving low type I error compared to the well-known MRP method. Two biological case studies on animals confirm that the STC preprocess successfully detects anomalies in the source trees while STC+PhySIC_IST provides well-resolved supertrees agreeing with current knowledge in systematics. Conclusion The paper introduces and tests two new methodologies, PhySIC_IST and STC, that demonstrate the interest in inferring non-plenary supertrees as well as preprocessing the source trees. An implementation of the methods is available at: . PMID:18834542

Providing health program information to vulnerable communities, such as Latino farmworkers, is difficult. This analysis describes the manner in which farmworkers receive information about the Affordable Care Act, comparing farmworkers with other Latinos. Interviews were conducted with 100 Latino farmworkers and 100 urban Latino North Carolina residents in 2015. Most farmworkers had received health information from a community organization. Trusted sources for health information were health care providers and community organizations. Sources that would influence decisions to enroll were Latino nurses and doctors, religious leaders, and family members. Traditional media, including oral presentation and printed material at the doctor's office, were preferred by the majority of farmworkers and non-farmworkers. Farmworkers used traditional electronic media: radio, television, and telephone. More non-farmworkers used current electronic media: e-mail and Internet. Latino farmworkers and non-farmworkers prefer traditional media in the context of a health care setting. They are willing to try contemporary electronic media for this information.

One of the crucial aspects of day-to-day laboratory information management is collection, storage and retrieval of information about research subjects and biomedical samples. An efficient link between sample data and experiment results is absolutely imperative for a successful outcome of a biomedical study. Currently available software solutions are largely limited to large-scale, expensive commercial Laboratory Information Management Systems (LIMS). Acquiring such LIMS indeed can bring laboratory information management to a higher level, but often implies sufficient investment of time, effort and funds, which are not always available. There is a clear need for lightweight open source systems for patient and sample information management. We present a web-based tool for submission, management and retrieval of sample and research subject data. The system secures confidentiality by separating anonymized sample information from individuals' records. It is simple and generic, and can be customised for various biomedical studies. Information can be both entered and accessed using the same web interface. User groups and their privileges can be defined. The system is open-source and is supplied with an on-line tutorial and necessary documentation. It has proven to be successful in a large international collaborative project. The presented system closes the gap between the need and the availability of lightweight software solutions for managing information in biomedical studies involving human research subjects.

Comparison Between a Typical Undergraduate Psychiatry Program in China and Canada--an Approach to Inform Psychiatry Education Reform in China.

Yu, Miaoyu; Law, Samuel; Dang, Kien; Byrne, Niall

2016-04-01

Psychiatry as a field and undergraduate psychiatry education (UPE) specifically have historically been in the periphery of medicine in China, unlike the relatively central role they occupy in the West. During the current economic reform, Chinese undergraduate medical education (UME) is undergoing significant changes and standardization under the auspices of the national accreditation body. A comparative study, using Bereday's comparative education methodology and Feldmann's evaluative criteria as theoretical frameworks, to gain understanding of the differences and similarities between China and the West in terms of UPE can contribute to the UME reform, and specifically UPE development in China, and promote cross-cultural understanding. The authors employed multi-sourced information to perform a comparative study of UPE, using the University of Toronto as a representative of the western model and Guangxi Medical University, a typical program in China, as the Chinese counterpart. Key contrasts are numerous; highlights include the difference in age and level of education of the entrants to medical school, centrally vs. locally developed UPE curriculum, level of integration with the rest of medical education, visibility within the medical school, adequacy of teaching resources, amount of clinical learning experience, opportunity for supervision and mentoring, and methods of student assessment. Examination of the existing, multi-sourced information reveals some fundamental differences in the current UPE between the representative Chinese and western programs, reflecting historical, political, cultural, and socioeconomic circumstances of the respective settings. The current analyses show some areas worthy of further exploration to inform Chinese UPE reform. The current research is a practical beginning to the development of a deeper collaborative dialogue about psychiatry and its educational underpinnings between China and the West.

The Mock LISA Data Challenges are a program to demonstrate and encourage the development of data-analysis capabilities for LISA. Each round of challenges consists of several data sets containing simulated instrument noise and gravitational waves from sources of undisclosed parameters. Participants are asked to analyze the data sets and report the maximum information they can infer about the source parameters. The challenges are being released in rounds of increasing complexity and realism. Challenge 3. currently in progress, brings new source classes, now including cosmic-string cusps and primordial stochastic backgrounds, and more realistic signal models for supermassive black-hole inspirals and galactic double white dwarf binaries.

Triangulation refers to the use of multiple methods or data sources in qualitative research to develop a comprehensive understanding of phenomena (Patton, 1999). Triangulation also has been viewed as a qualitative research strategy to test validity through the convergence of information from different sources. Denzin (1978) and Patton (1999) identified four types of triangulation: (a) method triangulation, (b) investigator triangulation, (c) theory triangulation, and (d) data source triangulation. The current article will present the four types of triangulation followed by a discussion of the use of focus groups (FGs) and in-depth individual (IDI) interviews as an example of data source triangulation in qualitative inquiry.

Impact of Information and Communication Technology on Information Seeking Behavior of Users in Astronomy and Astrophysics Centers of India: A Survey

NASA Astrophysics Data System (ADS)

Sahu, H. K.; Singh, S. N.

2010-10-01

This study is based on a survey designed to determine the Information Seeking Behavior (ISB) of Astronomy and Astrophysics users in India. The main objective of the study is to determine the sources consulted and the general pattern of the information-gathering system of users and the impact of Information and Communication Technology (ICT) on the Astronomy and Astrophysics user's Information Seeking Behavior. It examines various Information and Communication Technology-based resources and methods of access and use. A descriptive sample stratified method has been used and data was collected using a questionnaire as the main tool. The response rate was 72%. Descriptive statistics were also employed and data have been presented in tables and graphs. The study is supported by earlier studies. It shows that Astronomy and Astrophysics users have developed a unique Information Seeking Behavior to carry out their education and research. The vast majority of respondents reported that more information is available from a variety of e-resources. Consequently, they are able to devote more time to seek out relevant information in the current Information and Communication Technology scenario. The study also indicates that respondents use a variety of information resources including e-resources for teaching and research. Books and online databases such as the NASA Astrophysics Data System (ADS) were considered more important as formal sources of information. E-mail and face-to-face communications are used extensively by users as informal sources of information. It also reveals that despite the presence of electronic sources, Astronomy and Astrophysics users are still using printed materials. This study should to help to improve various Information and Communication Technology-based services. It also suggests that GOI should adopt Information and Communication Technology-based Information Centers and Libraries services and recommends a network-based model for Astronomy and Astrophysics users.

2016-01-01

Objective The aim of the present study was to acquire information on brachytherapy resources in Korea through a national survey of radiation oncologists. Methods Between October 2014 and January 2015, a questionnaire on the current status of brachytherapy was distributed to all 86 radiation oncology departments in Korea. The questionnaire was divided into sections querying general information on human resources, brachytherapy equipment, and suggestions for future directions of brachytherapy policy in Korea. Results The response rate of the survey was 88.3%. The average number of radiation oncologists per center was 2.3. At the time of survey, 28 centers (36.8%) provided brachytherapy to patients. Among the 28 brachytherapy centers, 15 (53.5%) were located in in the capital Seoul and its surrounding metropolitan areas. All brachytherapy centers had a high-dose rate system using 192Ir (26 centers) or 60Co (two centers). Among the 26 centers using 192Ir sources, 11 treated fewer than 40 patients per year. In the two centers using 60Co sources, the number of patients per year was 16 and 120, respectively. The most frequently cited difficulties in performing brachytherapy were cost related. A total of 21 centers had a plan to sustain the current brachytherapy system, and four centers noted plans to upgrade their brachytherapy system. Two centers stated that they were considering discontinuation of brachytherapy due to cost burdens of radioisotope source replacement. Conclusion The present study illustrated the current status of brachytherapy in Korea. Financial difficulties were the major barriers to the practice of brachytherapy. PMID:27102244

In the two centers using (60)Co sources, the number of patients per year was 16 and 120, respectively. The most frequently cited difficulties in performing brachytherapy were cost related. A total of 21 centers had a plan to sustain the current brachytherapy system, and four centers noted plans to upgrade their brachytherapy system. Two centers stated that they were considering discontinuation of brachytherapy due to cost burdens of radioisotope source replacement. The present study illustrated the current status of brachytherapy in Korea. Financial difficulties were the major barriers to the practice of brachytherapy.

The selection, acquisition, and use of chemical protective clothing (CPC) at Department of Energy (DOE) facilities require up-to-date data and information on the performance, availability, and sources of such clothing. There are hundreds of types and more than one hundred principal manufacturers of CPC. Information on CPC is published in manufacturers` brochures and the technical literature. These information sources, however, have no standard format or terminology for describing products or the results of product testing. Furthermore, the literature and information is continually changing and growing. Consequently, DOE`s industrial hygienists and safety specialists are frequently confounded in their efforts to providemore » effective CPC to workers, by they in the field, the laboratory, or the plant. In recognition of the many advances and changes that have occurred and of the need to provide current information to its health and safety staff, the DOE has updated and modified the key appendices of the Guidelines/Chemical Protective Clothing. The updates appendices compose the majority of this update document, wherein they are called Sections. Each Section begins with a description of its format, content, abbreviations, units, and links with other Sections, as appropriate.« less

Logic-based assessment of the compatibility of UMLS ontology sources

PubMed Central

2011-01-01

Background The UMLS Metathesaurus (UMLS-Meta) is currently the most comprehensive effort for integrating independently-developed medical thesauri and ontologies. UMLS-Meta is being used in many applications, including PubMed and ClinicalTrials.gov. The integration of new sources combines automatic techniques, expert assessment, and auditing protocols. The automatic techniques currently in use, however, are mostly based on lexical algorithms and often disregard the semantics of the sources being integrated. Results In this paper, we argue that UMLS-Meta’s current design and auditing methodologies could be significantly enhanced by taking into account the logic-based semantics of the ontology sources. We provide empirical evidence suggesting that UMLS-Meta in its 2009AA version contains a significant number of errors; these errors become immediately apparent if the rich semantics of the ontology sources is taken into account, manifesting themselves as unintended logical consequences that follow from the ontology sources together with the information in UMLS-Meta. We then propose general principles and specific logic-based techniques to effectively detect and repair such errors. Conclusions Our results suggest that the methodologies employed in the design of UMLS-Meta are not only very costly in terms of human effort, but also error-prone. The techniques presented here can be useful for both reducing human effort in the design and maintenance of UMLS-Meta and improving the quality of its contents. PMID:21388571

Modern military intelligence operations involves a deluge of information from a large number of sources. A data ranking algorithm that enables the most valuable information to be reviewed first may improve timely and effective analysis. This ranking is termed the value of information (VoI) and its calculation is a current area of research within the US Army Research Laboratory (ARL). ARL has conducted an experiment to correlate the perceptions of subject matter experts with the ARL VoI model and additionally to construct a cognitive model of the ranking process and the amalgamation of supporting and conflicting information.

A Prototype System for Retrieval of Gene Functional Information

Folk, Lillian C.; Patrick, Timothy B.; Pattison, James S.; Wolfinger, Russell D.; Mitchell, Joyce A.

2003-01-01

Microarrays allow researchers to gather data about the expression patterns of thousands of genes simultaneously. Statistical analysis can reveal which genes show statistically significant results. Making biological sense of those results requires the retrieval of functional information about the genes thus identified, typically a manual gene-by-gene retrieval of information from various on-line databases. For experiments generating thousands of genes of interest, retrieval of functional information can become a significant bottleneck. To address this issue, we are currently developing a prototype system to automate the process of retrieval of functional information from multiple on-line sources. PMID:14728346

Contextual Information for the Potential Enhancement of Annual Radiation Protection Program Review Reports.

PubMed

Emery, Robert J; Gutiérrez, Janet M

2017-08-01

Organizations possessing sources of ionizing radiation are required to develop, document, and implement a "radiation protection program" that is commensurate with the scope and extent of permitted activities and sufficient to ensure compliance with basic radiation safety regulations. The radiation protection program must also be reviewed at least annually, assessing program content and implementation. A convenience sample assessment of web-accessible and voluntarily-submitted radiation protection program annual review reports revealed that while the reports consistently documented compliance with necessary regulatory elements, very few included any critical contextual information describing how important the ability to possess radiation sources was to the central mission of the organization. Information regarding how much radioactive material was currently possessed as compared to license limits was also missing. Summarized here are suggested contextual elements that can be considered for possible inclusion in annual radiation protection program reviews to enhance stakeholder understanding and appreciation of the importance of the ability to possess radiation sources and the importance of maintaining compliance with associated regulatory requirements.

Provision of smoking cessation support in the form of advice and information is central to increasing quit rates, including among people with mental illness (MI), who have 3-5 times higher odds of smoking than those without MI. This study investigated the extent and perceived utility of quit smoking advice and information available to Australian smokers with MI through face-to-face, semi-structured, in-depth interviews with 29 current smokers with MI. Qualitative analysis identified four major sources of quit smoking advice and information: (i) mental health practitioners; (ii) Quitline; (iii) social networks; and (iv) Internet and media. All identified sources, including formal sources (mental health practitioners and Quitline), were perceived as providing inadequate information about quitting smoking, particularly regarding optimal usage of nicotine replacement therapy (NRT). Social networks emerged as a substantial source of quit smoking advice and information, especially for nontraditional methods such as vaping. Participants showed high interest in receiving support from peer-led smoking cessation groups. A minority of participants reported that they had received quit smoking information from Internet and media; this was largely restricted to negative reports about e-cigarettes and short advertisements for nicotine replacement therapy. Our findings suggest that more can be done to provide smokers with MI with practical smoking cessation advice and support. Comprehensive information resources tailored for smokers with MI should be developed and disseminated via multiple pathways. We also recommend a number of policy and practice reforms to promote smoking cessation among those with MI. © 2018 Australian College of Mental Health Nurses Inc.

Inference of cosmological parameters from gravitational waves: Applications to second generation interferometers

NASA Astrophysics Data System (ADS)

Del Pozzo, Walter

2012-08-01

The advanced worldwide network of gravitational waves (GW) observatories is scheduled to begin operations within the current decade. Thanks to their improved sensitivity, they promise to yield a number of detections and thus to open new observational windows for astronomy and astrophysics. Among the scientific goals that should be achieved, there is the independent measurement of the value of the cosmological parameters, hence an independent test of the current cosmological paradigm. Because of the importance of such a task, a number of studies have evaluated the capabilities of GW telescopes in this respect. However, since GW do not yield information about the source redshift, different groups have made different assumptions regarding the means through which the GW redshift can be obtained. These different assumptions imply also different methodologies to solve this inference problem. This work presents a formalism based on Bayesian inference developed to facilitate the inclusion of all assumptions and prior information about a GW source within a single data analysis framework. This approach guarantees the minimization of information loss and the possibility of including naturally event-specific knowledge (such as the sky position for a gamma ray burst-GW coincident observation) in the analysis. The workings of the method are applied to a specific example, loosely designed along the lines of the method proposed by Schutz in 1986, in which one uses information from wide-field galaxy surveys as prior information for the location of a GW source. I show that combining the results from few tens of observations from a network of advanced interferometers will constrain the Hubble constant H0 to an accuracy of ˜4%-5% at 95% confidence.

2012-11-01

Life, following curative treatment, can be a struggle for former cancer patients. In this phase of their illness, social comparison information may help to improve a patient's quality of life (QOL). The objective of this study was to determine whether the effects of this information depend on the following two variables: (1) the individual's physical health and (2) the individual's sensitivity to social comparison. In the current study, the effects on a patient's QOL were tested that occur when they are listening to a psychological oncological expert talking about cancer patients' experiences. Three different recorded interviews with experts were compared (on negative emotions, effective coping, or both), and individual differences were tested as moderators. In addition, the expert source conditions were compared with a condition in which the source was not an expert but a former patient. In a randomized field experiment, 154 Dutch former cancer patients (M(age) = 55 years; 68% women) were assigned to one of the four conditions (three expert source and one former patient source condition). QOL was assessed after 2 months. The effects of the expert source conditions on QOL depended on the participants' physical health (good vs. poor) and on the participants' sensitivity to social comparison (whether the recipient reacts with contrast or identification), as indicated by significant three-way interactions (p < .001). Depending on these two variables, one of the three expert source conditions was at least as effective as the former patient source condition. The results show that desired and undesired effects are found when individual differences relevant to the processing of intervention information are examined. ©2012 The British Psychological Society.

Modern medicine is an increasingly complex activity , based on the evidence ; it consists of information from multiple sources : medical record text , sound recordings , images and videos generated by a large number of devices . Medical imaging is one of the most important sources of information since they offer comprehensive support of medical procedures for diagnosis and follow-up . However , the amount of information generated by image capturing gadgets quickly exceeds storage availability in radiology services , generating additional costs in devices with greater storage capacity . Besides , the current trend of developing applications in cloud computing has limitations, even though virtual storage is available from anywhere, connections are made through internet . In these scenarios the optimal use of information necessarily requires powerful compression algorithms adapted to medical activity needs . In this paper we present a review of compression techniques used for image storage , and a critical analysis of them from the point of view of their use in clinical settings.

SU-E-T-284: Revisiting Reference Dosimetry for the Model S700 Axxent 50 KV{sub p} Electronic Brachytherapy Source

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

Hiatt, JR; Rivard, MJ

2014-06-01

Purpose: The model S700 Axxent electronic brachytherapy source by Xoft was characterized in 2006 by Rivard et al. The source design was modified in 2006 to include a plastic centering insert at the source tip to more accurately position the anode. The objectives of the current study were to establish an accurate Monte Carlo source model for simulation purposes, to dosimetrically characterize the new source and obtain its TG-43 brachytherapy dosimetry parameters, and to determine dose differences between the source with and without the centering insert. Methods: Design information from dissected sources and vendor-supplied CAD drawings were used to devisemore » the source model for radiation transport simulations of dose distributions in a water phantom. Collision kerma was estimated as a function of radial distance, r, and polar angle, θ, for determination of reference TG-43 dosimetry parameters. Simulations were run for 10{sup 10} histories, resulting in statistical uncertainties on the transverse plane of 0.03% at r=1 cm and 0.08% at r=10 cm. Results: The dose rate distribution the transverse plane did not change beyond 2% between the 2006 model and the current study. While differences exceeding 15% were observed near the source distal tip, these diminished to within 2% for r>1.5 cm. Differences exceeding a factor of two were observed near θ=150° and in contact with the source, but diminished to within 20% at r=10 cm. Conclusions: Changes in source design influenced the overall dose rate and distribution by more than 2% over a third of the available solid angle external from the source. For clinical applications using balloons or applicators with tissue located within 5 cm from the source, dose differences exceeding 2% were observed only for θ>110°. This study carefully examined the current source geometry and presents a modern reference TG-43 dosimetry dataset for the model S700 source.« less

Validation and calibration of structural models that combine information from multiple sources.

PubMed

Dahabreh, Issa J; Wong, John B; Trikalinos, Thomas A

2017-02-01

Mathematical models that attempt to capture structural relationships between their components and combine information from multiple sources are increasingly used in medicine. Areas covered: We provide an overview of methods for model validation and calibration and survey studies comparing alternative approaches. Expert commentary: Model validation entails a confrontation of models with data, background knowledge, and other models, and can inform judgments about model credibility. Calibration involves selecting parameter values to improve the agreement of model outputs with data. When the goal of modeling is quantitative inference on the effects of interventions or forecasting, calibration can be viewed as estimation. This view clarifies issues related to parameter identifiability and facilitates formal model validation and the examination of consistency among different sources of information. In contrast, when the goal of modeling is the generation of qualitative insights about the modeled phenomenon, calibration is a rather informal process for selecting inputs that result in model behavior that roughly reproduces select aspects of the modeled phenomenon and cannot be equated to an estimation procedure. Current empirical research on validation and calibration methods consists primarily of methodological appraisals or case-studies of alternative techniques and cannot address the numerous complex and multifaceted methodological decisions that modelers must make. Further research is needed on different approaches for developing and validating complex models that combine evidence from multiple sources.

Patients' need for health information is widely recognized. The aim of this study was to determine how patients currently receive and rate this information. Additionally, we aimed to identify the needs and expectations of citizens of the autonomous region of Andalusia in this regard. We performed a qualitative research study involving semi-structured telephone interviews with participants. A total of 48 interviews were performed in people with different social and health profiles from a structural sample. The final selection of persons to be interviewed was made using the snow-ball sampling method. Interview material was analyzed by means of NUDIST vivo 1.1 software-aided content analysis. The interviewees reported receiving health information mainly from healthcare personnel. Supplementary information sources were the internet, associations and publications. The interviewees expressed different degrees of satisfaction with the health information received, depending on its understandability and the amount of detail provided. The persons interviewed reported that they would like to receive all the information possible on their health-illness-care process and would prefer this information to come mainly from physicians. Information about the health-illness-care process should center on practical issues. Physicians are the first and principal source of medical information and consequently communication skills should be promoted in this collective through training courses. Additionally, alternative sources of information used by citizens should be strengthened to provide high-quality health information. Copyright © 2008 Sociedad Española de Calidad Asistencial.

Temporal and visual source memory deficits among ecstasy/polydrug users.

Fisk, John E; Gallagher, Denis T; Hadjiefthyvoulou, Florentia; Montgomery, Catharine

2014-03-01

We wished to investigate whether source memory judgements are adversely affected by recreational illicit drug use. Sixty-two ecstasy/polydrug users and 75 non ecstasy users completed a source memory task, in which they tried to determine whether or not a word had been previously presented and if so, attempted to recall the format, location and temporal position in which the word had occurred. While not differing in terms of the number of hits and false positive responses, ecstasy/polydrug users adopted a more liberal decision criterion when judging if a word had been presented previously. With regard to source memory, users were less able to determine the format in which words had been presented (upper versus lower case). Female users did worse than female nonusers in determining which list (first or second) a word was from. Unexpectedly, the current frequency of cocaine use was negative associated with list and case source memory performance. Given the role that source memory plays in everyday cognition, those who use cocaine more frequently might have more difficulty in everyday tasks such as recalling the sources of crucial information or making use of contextual information as an aid to learning.

To assess progress in meeting young people's sex education needs in Britain by examining the current situation and changes over the past 20 years in sources of information about sexual matters and unmet information needs. Cross-sectional probability sample surveys. British general population. 3869 men and women aged 16-24 years, interviewed 2010-2012 for the third National Survey of Sexual Attitudes & Lifestyles (Natsal-3), compared with 16-24 year-olds in Natsal-1 (1990-1991; 792 men and women) and Natsal-2 (1999-2001; 2673 men and women). Reported source of information about sexual matters, unmet information needs and preferred source of additional information. Between 1990 and 2012, the proportion citing school lessons as their main source of information about sexual matters increased from 28.2% (95% CI 24.6 to 32.1) to 40.3% (95% CI 38.6 to 42.1). In 2010-2012, parents were reported as a main source by only 7.1% (95% CI 5.8 to 8.7) of men and 14.1% (95% CI 12.6 to 15.7) of women and, for women, were less commonly reported than in 1999-2001 (21.7%; 95% CI 19.6 to 24.0). Most young people reported not knowing enough when they first felt ready for sexual experience (68.1% men, 70.6% women), and this did not change substantially over time. They wanted more information about psychosexual matters (41.6% men, 46.8% women), as well as sexually transmitted infections (27.8% men, 29.8% women) and, for women, contraception (27.5%). Young people primarily wanted this information from school, parents or health professionals. Over the past 20 years, young people have increasingly identified school lessons as their main source of information about sex, although they continue to report needing more information on a broad range of topics. The findings support the expressed need for improved sex and relationships education in schools alongside greater involvement of parents and health professionals.

Gathering patient information to contain an outbreak of Listeria monocytogenes is difficult because of the patients' severe illness or death. Extending the range of interviewees to acquire epidemiological data can thus be important to maximise information. We built the current analysis on a case-case outbreak investigation conducted during a Swiss listeriosis outbreak between 30 January and 11 May 2014, including 31 patients with confirmed L. monocytogenes infection. We interviewed treating physicians and patients or their next of kin to gather information on clinical aspects, eating habits and food consumption. We compared the different information sources with regards to their potential to provide specific, complete and rapid information on the affected population and their food consumption history. We obtained a 100% response rate among physicians, providing detailed information on the affected population by describing health status, underlying conditions, and signs and symptoms. Detailed information on food history could not be obtained from physicians, making the information vague and unspecific. Less than 50% of patients could be interviewed, limiting our information base. Nevertheless, patient information on the food history was sufficiently detailed and helped to identify the outbreak source CONCLUSIONS: Outbreak investigation teams confronted with limited information from patients and with small numbers of cases can enhance information on the affected population and the outbreak source by combining information from physicians and patients. Physicians provided comprehensive information on signs and symptoms, underlying conditions and the general health status. Patients remain vital to provide detailed information on the food consumption history.

Library use and information-seeking behavior of veterinary medical students revisited in the electronic environment.

Veterinary medical students at Iowa State University were surveyed in January of 1997 to determine their general use of the Veterinary Medical Library and how they sought information in an electronic environment. Comparisons were made between this study and one conducted a decade ago to determine the effect of the growth in electronic resources on student library use and information-seeking behavior. The basic patterns of student activities in the library, resources used to find current information, and resources anticipated for future education needs remained unchanged. The 1997 students used the library most frequently for photocopying, office supplies, and studying coursework; they preferred textbooks and handouts as sources of current information. However, when these students went beyond textbooks and handouts to seek current information, a major shift was seen from the use of print indexes and abstracts in 1987 towards the use of computerized indexes and other electronic resources in 1997. Almost 60% of the students reported using the Internet for locating current information. Overall use of electronic materials was highest among a group of students receiving the problem-based learning method of instruction. Most of the students surveyed in 1997 indicated that electronic resources would have some degree of importance to them for future education needs. The electronic environment has provided new opportunities for information professionals to help prepare future veterinarians, some of whom will be practicing in remote geographical locations, to access the wealth of information and services available on the Internet and Web.

Patient choice, Internet based information sources, and perceptions of health care: Evidence from Sweden using survey data from 2010 and 2013.

PubMed

Wahlstedt, Emma; Ekman, Björn

2016-08-01

Several countries have increased patients' abilities to choose their health care providers, frequently under the assumption that patients are themselves the best agents to make such decisions. In parallel, national and regional health authorities have enhanced access to Internet based information sources (IBIS) to assist patients in making an informed choice. Relatively little, however, is known about the effect that the use of such sources has on key outcomes, including patients' perceptions of care. The aim of this study is to analyze the role of the Internet for patients' confidence in the provider and perceived access to care in the context of choice based reforms in Sweden. The study uses a regional, population health survey from the southern part of Sweden. Non-parametric chi-square tests are used to assess the nature of Internet users, including their gender, age and socioeconomic status. Logistic regression models are specified to analyze the role of IBIS on patient perceptions of care while controlling for other factors. Actual use of Internet based information sources for health care was relatively low in 2010 and only somewhat higher in 2013. The characteristics of IBIS users varied significantly across different population groups, such that they were younger, more educated, female, and also considered themselves to be in better health compared with those who reported not using this source of health care information. Finally, the average IBIS user was less likely to report having a high level of satisfaction with respect to their primary care use; OR 0.69 [95 % CI: 0.54-0,87] and OR 0.52 [95 % CI: 0,41-0,66], for confidence in provider and perceived access to care, respectively, in 2013. Despite health agencies' attempts to make information on health care providers available on the Internet, this source of health care information is not used to any large extent in the current sample. The fact that some people use this source of information more compared with others suggests the need to consider alternative ways of informing the general public about choice options. The use of Internet based sources may also be linked with the experience of actually using health services, which suggests a need to further analyze this complex consumer behavior process.

The availability of two contemporary sources of information about coronary artery bypass graft (CABG) interventions, allowed 1) to verify the feasibility of performing outcome evaluation studies using administrative data sources, and 2) to compare hospital performance obtainable using the CABG Project clinical database with hospital performance derived from the use of current administrative data. Interventions recorded in the CABG Project were linked to the hospital discharge record (HDR) administrative database. Only the linked records were considered for subsequent analyses (46% of the total CABG Project). A new selected population "clinical card-HDR" was then defined. Two independent risk-adjustment models were applied, each of them using information derived from one of the two different sources. Then, HDR information was supplemented with some patient preoperative conditions from the CABG clinical database. The two models were compared in terms of their adaptability to data. Hospital performances identified by the two different models and significantly different from the mean was compared. In only 4 of the 13 hospitals considered for analysis, the results obtained using the HDR model did not completely overlap with those obtained by the CABG model. When comparing statistical parameters of the HDR model and the HDR model + patient preoperative conditions, the latter showed the best adaptability to data. In this "clinical card-HDR" population, hospital performance assessment obtained using information from the clinical database is similar to that derived from the use of current administrative data. However, when risk-adjustment models built on administrative databases are supplemented with a few clinical variables, their statistical parameters improve and hospital performance assessment becomes more accurate.

Nowadays, the need of energy has been increasing day by day with the population growth and the advancements of technology. In this study, the current state of nuclear, wind and solar energy on the worldwide has been generally investigated. The general assessments have been made based on Turkey's energy potential and the evaluation situation of this potential. The current political structures of countries are generally assessed and under this policy, the last situation and the latest implemented innovations are given. Turkey's energy demand is constantly increasing and Turkey is a country that needs to energy imports. This is a need for new energy sources to meet the growing need for energy. Nuclear, wind and solar energy are the new sources of energy to the fore in our country recently. In this study is given general information on the usage of energy sources of making and some deficiencies were been emphasized by political considerations in this regard.

On simulation of local fluxes in molecular junctions

NASA Astrophysics Data System (ADS)

Cabra, Gabriel; Jensen, Anders; Galperin, Michael

2018-05-01

We present a pedagogical review of the current density simulation in molecular junction models indicating its advantages and deficiencies in analysis of local junction transport characteristics. In particular, we argue that current density is a universal tool which provides more information than traditionally simulated bond currents, especially when discussing inelastic processes. However, current density simulations are sensitive to the choice of basis and electronic structure method. We note that while discussing the local current conservation in junctions, one has to account for the source term caused by the open character of the system and intra-molecular interactions. Our considerations are illustrated with numerical simulations of a benzenedithiol molecular junction.

Information literacy: implications for perioperative nurses.

PubMed

Byrne, Michelle M

2011-02-01

The concept of information literacy may be new to some perioperative nurses; however, embracing this concept will help nurses identify situations that necessitate gaining more information, locate and access information sources, evaluate and analyze data, and cite information in compliance with copyright and fair use laws. The culture of health care is continually changing as a result of new technology and new methods to improve patient care, and this creates an information explosion. Perioperative educators should add information literacy as a strategic goal for obtaining Magnet status because it is foundational to evidence-based practice. Administrators also should advocate to obtain resources that will enable nurses to access information that addresses current patient care issues.

To assess the current state of the art and the contribution of Free/Libre Open Source Software in health care (FLOSS-HC). The review is based on a narrative review of the scientific literature as well as sources in the context of FLOSS-HC available through the Internet. All relevant available sources have been integrated into the MedFLOSS database and are freely available to the community. The literature review reveals that publications about FLOSS-HC are scarce. The largest part of information about FLOSS-HC is available on dedicated websites and not in the academic literature. There are currently FLOSS alternatives available for nearly every specialty in health care. Maturity and quality varies considerably and there is little information available on the percentage of systems that are actually used in health care delivery. The global impact of FLOSS-HC is still very limited and no figures on the penetration and usage of FLOSS-HC are available. However, there has been a considerable growth in the last 5 to 10 years. While there where only few systems available a decade ago, in the meantime many systems got available (e.g., more than 300 in the MedFLOSS database). While FLOSS concepts play an important role in most IT related sectors (e.g., telecommunications, embedded devices) the healthcare industry is lagging behind this trend.

SPod Progress Summary Slides | Science Inventory | US EPA

EPA Pesticide Factsheets

This presentation describes the draft “open source” design package for the SPod fenceline sensor. The SPod is a low cost, solar-powered system that combines wind field and air pollutant concentration measurements to detect emission plumes and help locate the source of emissions. The current design works only in “near-fenceline” applications where localized source emission plumes may be present. The SPod uses data analysis software (described elsewhere) to separate baseline drift from the plume signal of interest. This software is necessary for proper operation of the SPod. Because the SPod is designed to detect source emissions plumes, it is not useful for ambient applications large distances away from sources. The current SPod detects a subset of air pollutants that can be ionized with a 10.6 eV photoionization detector (PID). In the future, other air pollutant sensors may be used. The purpose of this presentation and related postings is to advance design concepts in the low-cost fenceline sensor area with any interested parties. The SPod is a work in progress with continued advances incorporated on an ongoing basis. This document is posted on an EPA share drive along with other information that describes the use operation and limitations of the SPod. These slides summarize the SPod design, purpose, and progress as of June, 2016. These slides will be posted on the EPA SPod Share Site along with design information and other materials that communicat

Towards democracy in spatial planning through spatial information built by communities: The investigation of spatial information built by citizens from participatory mapping to volunteered geographic information in Indonesia

NASA Astrophysics Data System (ADS)

Yudono, Adipandang

2017-06-01

Recently, crowd-sourced information is used to produce and improve collective knowledge and community capacity building. Triggered by broadening and expanding access to the Internet and cellular telephones, the utilisation of crowd-sourcing for policy advocacy, e-government and e-participation has increased globally [1]. Crowd-sourced information can conceivably support government’s or general social initiatives to inform, counsel, and cooperate, by engaging subjects and empowering decentralisation and democratization [2]. Crowd-sourcing has turned into a major technique for interactive mapping initiatives by urban or rural community because of its capability to incorporate a wide range of data. Continuously accumulated spatial data can be sorted, layered, and envisioned in ways that even beginners can comprehend with ease. Interactive spatial visualization has the possibility to be a useful democratic planning tool to empower citizens participating in spatial data provision and sharing in government programmes. Since the global emergence of World Wide Web (WWW) technology, the interaction between information providers and users has increased. Local communities are able to produce and share spatial data to produce web interfaces with territorial information in mapping application programming interfaces (APIs) public, such as Google maps, OSM and Wikimapia [3][4][5]. In terms of the democratic spatial planning action, Volunteered Geographic Information (VGI) is considered an effective voluntary method of helping people feel comfortable with the technology and other co-participants in order to shape coalitions of local knowledge. This paper has aim to investigate ‘How is spatial data created by citizens used in Indonesia?’ by discussing the characteristics of spatial data usage by citizens to support spatial policy formulation, starting with the history of participatory mapping to current VGI development in Indonesia.

Exploration of Deaf People’s Health Information Sources and Techniques for Information Delivery in Cape Town: A Qualitative Study for the Design and Development of a Mobile Health App

Glaser, Meryl; Tucker, William David; Diehl, Jan Carel

2016-01-01

Background Many cultural and linguistic Deaf people in South Africa face disparity when accessing health information because of social and language barriers. The number of certified South African Sign Language interpreters (SASLIs) is also insufficient to meet the demand of the Deaf population in the country. Our research team, in collaboration with the Deaf communities in Cape Town, devised a mobile health app called SignSupport to bridge the communication gaps in health care contexts. We consequently plan to extend our work with a Health Knowledge Transfer System (HKTS) to provide Deaf people with accessible, understandable, and accurate health information. We conducted an explorative study to prepare the groundwork for the design and development of the system. Objectives To investigate the current modes of health information distributed to Deaf people in Cape Town, identify the health information sources Deaf people prefer and their reasons, and define effective techniques for delivering understandable information to generate the groundwork for the mobile health app development with and for Deaf people. Methods A qualitative methodology using semistructured interviews with sensitizing tools was used in a community-based codesign setting. A total of 23 Deaf people and 10 health professionals participated in this study. Inductive and deductive coding was used for the analysis. Results Deaf people currently have access to 4 modes of health information distribution through: Deaf and other relevant organizations, hearing health professionals, personal interactions, and the mass media. Their preferred and accessible sources are those delivering information in signed language and with communication techniques that match Deaf people’s communication needs. Accessible and accurate health information can be delivered to Deaf people by 3 effective techniques: using signed language including its dialects, through health drama with its combined techniques, and accompanying the information with pictures in combination with simple text descriptions. Conclusions We can apply the knowledge gained from this exploration to build the groundwork of the mobile health information system. We see an opportunity to design an HKTS to assist the information delivery during the patient-health professional interactions in primary health care settings. Deaf people want to understand the information relevant to their diagnosed disease and its self-management. The 3 identified effective techniques will be applied to deliver health information through the mobile health app. PMID:27836819

Tank Information System (tis): a Case Study in Migrating Web Mapping Application from Flex to Dojo for Arcgis Server and then to Open Source

NASA Astrophysics Data System (ADS)

Pulsani, B. R.

2017-11-01

Tank Information System is a web application which provides comprehensive information about minor irrigation tanks of Telangana State. As part of the program, a web mapping application using Flex and ArcGIS server was developed to make the data available to the public. In course of time as Flex be-came outdated, a migration of the client interface to the latest JavaScript based technologies was carried out. Initially, the Flex based application was migrated to ArcGIS JavaScript API using Dojo Toolkit. Both the client applications used published services from ArcGIS server. To check the migration pattern from proprietary to open source, the JavaScript based ArcGIS application was later migrated to OpenLayers and Dojo Toolkit which used published service from GeoServer. The migration pattern noticed in the study especially emphasizes upon the use of Dojo Toolkit and PostgreSQL database for ArcGIS server so that migration to open source could be performed effortlessly. The current ap-plication provides a case in study which could assist organizations in migrating their proprietary based ArcGIS web applications to open source. Furthermore, the study reveals cost benefits of adopting open source against commercial software's.

Protecting single-photon entanglement with practical entanglement source

NASA Astrophysics Data System (ADS)

Zhou, Lan; Ou-Yang, Yang; Wang, Lei; Sheng, Yu-Bo

2017-06-01

Single-photon entanglement (SPE) is important for quantum communication and quantum information processing. However, SPE is sensitive to photon loss. In this paper, we discuss a linear optical amplification protocol for protecting SPE. Different from the previous protocols, we exploit the practical spontaneous parametric down-conversion (SPDC) source to realize the amplification, for the ideal entanglement source is unavailable in current quantum technology. Moreover, we prove that the amplification using the entanglement generated from SPDC source as auxiliary is better than the amplification assisted with single photons. The reason is that the vacuum state from SPDC source will not affect the amplification, so that it can be eliminated automatically. This protocol may be useful in future long-distance quantum communications.

On the Relationship Between Neighborhood Perception, Length of Residence and Co-Ethnic Concentration

Saenz, Joseph

2014-01-01

We investigate how co-ethnic concentration and length of residence are related to neighborhood perception in aged Mexican Americans, and discuss sources of information for measuring social environments. Neighborhood perception scale, length of residence in current home, and all individual-level covariates in a hierarchical linear model are derived from data on community-dwelling older adults. Tract-level measures are obtained from Census data. We find no relationship between co-ethnic concentration and positive neighborhood perception, and find a direct relationship between length of residence and positive neighborhood perception. Until further evidence is found, different sources of information when measuring place should be treated equally. PMID:25057331

Spatial Dmbs Architecture for a Free and Open Source Bim

2017-08-01

Recent research on the field of Building Information Modelling (BIM) technology, revealed that except of a few, accessible and free BIM viewers there is a lack of Free & Open Source Software (FOSS) BIM software for the complete BIM process. With this in mind and considering BIM as the technological advancement of Computer-Aided Design (CAD) systems, the current work proposes the use of a FOSS CAD software in order to extend its capabilities and transform it gradually into a FOSS BIM platform. Towards this undertaking, a first approach on developing a spatial Database Management System (DBMS) able to store, organize and manage the overall amount of information within a single application, is presented.

The neurocognitive basis of borrowed context information.

PubMed

O'Neill, Meagan; Diana, Rachel A

2017-06-01

Falsely remembered items can be accompanied by episodic context retrieval. This finding is difficult to explain because there is no episode that binds the remembered item to the experimenter-controlled context features. The current study examines the neural correlates of false context retrieval when the context features can be traced to encoding episodes of semantically-similar items. Our neuroimaging results support a "dissociated source" mechanism for context borrowing in false memory. We found that parahippocampal cortex (PHc) activation, thought to indicate context retrieval, was greater during trials that involved context borrowing (an incorrect, but plausible source decision) than during baseline correct context retrieval. In contrast, hippocampal activation, thought to indicate retrieval of an episodic binding, was stronger during correct source retrieval than during context borrowing. Vivid context retrieval during false recollection experiences was also indicated by increased activation in visual perceptual regions for context borrowing as compared to other incorrect source judgments. The pattern of findings suggests that context borrowing can arise when unusually strong activation of a semantically-related item's contextual features drives relatively weak retrieval of the associated episodic binding with failure to confirm the item information within that binding. This dissociated source retrieval mechanism suggests that context-driven episodic retrieval does not necessarily lead to retrieval of specific item details. That is, source information can be retrieved in the absence of item memory. Copyright © 2017 Elsevier Ltd. All rights reserved.

Estimating air emissions from ships: Meta-analysis of modelling approaches and available data sources

NASA Astrophysics Data System (ADS)

Miola, Apollonia; Ciuffo, Biagio

2011-04-01

Maritime transport plays a central role in the transport sector's sustainability debate. Its contribution to air pollution and greenhouse gases is significant. An effective policy strategy to regulate air emissions requires their robust estimation in terms of quantification and location. This paper provides a critical analysis of the ship emission modelling approaches and data sources available, identifying their limits and constraints. It classifies the main methodologies on the basis of the approach followed (bottom-up or top-down) for the evaluation and geographic characterisation of emissions. The analysis highlights the uncertainty of results from the different methods. This is mainly due to the level of uncertainty connected with the sources of information that are used as inputs to the different studies. This paper describes the sources of the information required for these analyses, paying particular attention to AIS data and to the possible problems associated with their use. One way of reducing the overall uncertainty in the results could be the simultaneous use of different sources of information. This paper presents an alternative methodology based on this approach. As a final remark, it can be expected that new approaches to the problem together with more reliable data sources over the coming years could give more impetus to the debate on the global impact of maritime traffic on the environment that, currently, has only reached agreement via the "consensus" estimates provided by IMO (2009).

Teaching Chemical Information in a Liberal Arts Curriculum

We first offered Chemical Information as a one-credit, semester-long course in 1993 and have continued to team-teach it each fall. We offer this summary of our course as a model that might be adapted in other settings, acknowledging that no single course can adequately prepare chemists for the many challenges involved in finding, evaluating, and utilizing chemical information. The focus on information retrieval, evaluation, and presentation in a separate course has worked well for us, successfully integrating concepts of information literacy in a chemical context. We cover a wide array of topics, beginning with print and electronic resources on our campus and moving quickly to databases and other sources on the Internet. Searching CA Online via STN Express and STN Easy is emphasized more than any other single source. We have described the course in some detail elsewhere and give here a synopsis of our current approach and significant changes in the course over the last two years.

The growing base of information about ecosystem services generated by ecologists, economists, and other scientists could improve the implementation, monitoring, and evaluation of commodity-sourcing standards being adopted by corporations to mitigate risk in their supply chains and achieve sustainability goals. This review examines various ways that information about ecosystem services could facilitate compliance with and auditing of commodity-sourcing standards. We also identify gaps in the current state of knowledge on the ecological effectiveness of sustainability standards and demonstrate how ecosystem-service information could complement existing monitoring efforts to build credible evidence. This paper is a call to the ecosystem-service scientists to engage in this decision context and tailor the information they are generating to the needs of the standards community, which we argue would offer greater efficiency of standards implementation for producers and enhanced effectiveness for standard scheme owners and corporations, and should thus lead to more sustainable outcomes for people and nature. © 2015 New York Academy of Sciences.

Pain research using Veterans Health Administration electronic and administrative data sources.

Abel, Erica A; Brandt, Cynthia A; Czlapinski, Rebecca; Goulet, Joseph L

2016-01-01

Health services researchers are using Veterans Health Administration (VHA) electronic health record (EHR) data sources to examine the prevalence, treatment, and outcomes of pain among Veterans in VHA care. Little guidance currently exists on using these data; thus, findings may vary depending on the methods, data sources, and definitions used. We sought to identify current practices in order to provide guidance to future pain researchers. We conducted an anonymous survey of VHA-affiliated researchers participating in a monthly national pain research teleconference. Thirty-two researchers (89%) responded: 75% conducted pain-focused research, 78% used pain intensity numeric rating screening scale (NRS) scores to identify pain, 41% used International Classification of Diseases-9th Revision codes, and 57% distinguished between chronic and acute pain using either NRS scores or pharmacy data. The NRS and pharmacy data were rated as the most valid pain data sources. Of respondents, 48% reported the EHR data sources were adequate for pain research, while 45% had published peer-reviewed articles based on the data. Despite limitations, VHA researchers are increasingly using EHR data for pain research, and several common methods were identified. More information on the performance characteristics of these data sources and definitions is needed.

Climate Change Impacts on Environmental and Human Exposure to Mercury in the Arctic

2015-01-01

This paper reviews information from the literature and the EU ArcRisk project to assess whether climate change results in an increase or decrease in exposure to mercury (Hg) in the Arctic, and if this in turn will impact the risks related to its harmful effects. It presents the state-of-the art of knowledge on atmospheric mercury emissions from anthropogenic sources worldwide, the long-range transport to the Arctic, and it discusses the likely environmental fate and exposure effects on population groups in the Arctic under climate change conditions. The paper also includes information about the likely synergy effects (co-benefits) current and new climate change polices and mitigation options might have on mercury emissions reductions in the future. The review concludes that reductions of mercury emission from anthropogenic sources worldwide would need to be introduced as soon as possible in order to assure lowering the adverse impact of climate change on human health. Scientific information currently available, however, is not in the position to clearly answer whether climate change will increase or decrease the risk of exposure to mercury in the Arctic. New research should therefore be undertaken to model the relationships between climate change and mercury exposure. PMID:25837201

2014-01-01

The number of Natural Language Processing (NLP) tools and systems for processing clinical free-text has grown as interest and processing capability have surged. Unfortunately any two systems typically cannot simply interoperate, even when both are built upon a framework designed to facilitate the creation of pluggable components. We present two ongoing activities promoting open source clinical NLP. The Open Health Natural Language Processing (OHNLP) Consortium was originally founded to foster a collaborative community around clinical NLP, releasing UIMA-based open source software. OHNLP’s mission currently includes maintaining a catalog of clinical NLP software and providing interfaces to simplify the interaction of NLP systems. Meanwhile, Apache cTAKES aims to integrate best-of-breed annotators, providing a world-class NLP system for accessing clinical information within free-text. These two activities are complementary. OHNLP promotes open source clinical NLP activities in the research community and Apache cTAKES bridges research to the health information technology (HIT) practice. PMID:25954581

2017-01-01

Background: Deep brain stimulation (DBS) is under investigation for severe obsessive-compulsive disorder (OCD) resistant to other therapies. The number of implants worldwide is slowly increasing. Therefore, it is of importance to explore knowledge and concerns of this novel treatment among patients and their psychiatric healthcare contacts. This information is relevant for scientific professionals working with clinical studies for DBS for this indication. Especially, for future study designs and the creation of information targeting healthcare professionals and patients. The aim of this study was to explore the knowledge and concerns toward DBS among patients with OCD, psychiatrists, and cognitive behavioral therapists. Methods: The study was conducted through web-based surveys for the aimed target groups –psychiatrist, patients, and cognitive behavioral therapists. The surveys contained questions regarding previous knowledge of DBS, source of knowledge, attitudes, and concerns towards the therapy. Results: The main source of information was from scientific sources among psychiatrists and psychotherapists. The patient's main source of information was the media. Common concerns among the groups included complications from surgery, anesthesia, stimulation side effects, and the novelty of the treatment. Specific concerns for the groups included; personality changes mentioned by patients and psychotherapists, and ethical concerns among psychiatrists. Conclusion: There are challenges for DBS in OCD as identified by the participants of this study; source and quality of information, efficacy, potential adverse effects, and eligibility. In all of which the current evidence base still is limited. A broad research agenda is needed for studies going forward. PMID:29285414

Modernization and new technologies: Coping with the information explosion

NASA Technical Reports Server (NTRS)

Blados, Walter R.; Cotter, Gladys A.

1993-01-01

Information has become a valuable and strategic resource in all societies and economies. Scientific and technical information is especially important in developing and maintaining a strong national science and technology base. The expanding use of information technology, the growth of interdisciplinary research, and an increase in international collaboration are changing characteristics of information. This modernization effort applies new technology to current processes to provide near-term benefits to the user. At the same time, we are developing a long-term modernization strategy designed to transition the program to a multimedia, global 'library without walls'. Notwithstanding this modernization program, it is recogized that no one information center can hope to collect all the relevant data. We see information and information systems changing and becoming more international in scope. We are finding that many nations are expending resources on national systems which duplicate each other. At the same time that this duplication exists, many useful sources of aerospace information are not being collected to cover expanded sources of information. This paper reviews the NASA modernization program and raises for consideration new possibilities for unification of the various aerospace database efforts toward a cooperative international aerospace database initiative, one that can optimize the cost/benefit equation for all participants.

Current status of cadaver sources in Turkey and a wake-up call for Turkish anatomists.

Gürses, İlke Ali; Coşkun, Osman; Öztürk, Adnan

2018-03-01

Persisting difficulties in body procurement in Turkey led to the acquisition of donated, unclaimed, autopsied, and imported bodies regulated under current legislature. Yet, no study had investigated the extent of the on-going cadaver problem. This study was aimed to outline cadaver sources in anatomy departments and their effectiveness by means of an online survey. Additionally, official websites of each department were investigated regarding any information on body donation. Unclaimed cadavers (84.8%) were the major source for anatomy departments, followed by donated (50%) and imported cadavers (39.1%). Foundation-based medical faculties were more likely to import cadavers (P = 0.008). There was a moderate increase (r s  = 0.567; P = 0.018) in donation registrations to our department after 2000. The departments in cities with significantly higher City-Based Gross Domestic Product measures (US$9,900 vs. US$16,772, P = 0.041), frequencies for mid- or high-school graduates (30.4% vs. 31.3%, P = 0.041), and frequencies for under- or post-graduates (13.1% vs. 15.8%, P = 0.24) had managed to use donated cadavers. Anatomy departments' major reasons for using unclaimed cadavers were education (45.9%), unclaimed cadavers being the only source (24.3%), and receiving inadequate donations (21.6%). Nine out of seventy-four departments (12.2%) provided information regarding body donation on their websites. Body procurement remains as a serious problem in Turkey and it is apparent that current legislature does not provide a sufficient cadaver inflow. Similarly, anatomy departments' effectiveness in public awareness of body donation and support in the National Body Donation Campaign seems questionable.

Positive emotion can protect against source memory impairment.

PubMed

MacKenzie, Graham; Powell, Tim F; Donaldson, David I

2015-01-01

Despite widespread belief that memory is enhanced by emotion, evidence also suggests that emotion can impair memory. Here we test predictions inspired by object-based binding theory, which states that memory enhancement or impairment depends on the nature of the information to be retrieved. We investigated emotional memory in the context of source retrieval, using images of scenes that were negative, neutral or positive in valence. At study each scene was paired with a colour and during retrieval participants reported the source colour for recognised scenes. Critically, we isolated effects of valence by equating stimulus arousal across conditions. In Experiment 1 colour borders surrounded scenes at study: memory impairment was found for both negative and positive scenes. Experiment 2 used colours superimposed over scenes at study: valence affected source retrieval, with memory impairment for negative scenes only. These findings challenge current theories of emotional memory by showing that emotion can impair memory for both intrinsic and extrinsic source information, even when arousal is equated between emotional and neutral stimuli, and by dissociating the effects of positive and negative emotion on episodic memory retrieval.

Medial prefrontal cortex supports source memory accuracy for self-referenced items

PubMed Central

Leshikar, Eric D.; Duarte, Audrey

2013-01-01

Previous behavioral work suggests that processing information in relation to the self enhances subsequent item recognition. Neuroimaging evidence further suggests that regions along the cortical midline, particularly those of the medial prefrontal cortex, underlie this benefit. There has been little work to date, however, on the effects of self-referential encoding on source memory accuracy or whether the medial prefrontal cortex might contribute to source memory for self-referenced materials. In the current study, we used fMRI to measure neural activity while participants studied and subsequently retrieved pictures of common objects superimposed on one of two background scenes (sources) under either self-reference or self-external encoding instructions. Both item recognition and source recognition were better for objects encoded self-referentially than self-externally. Neural activity predictive of source accuracy was observed in the medial prefrontal cortex (BA 10) at the time of study for self-referentially but not self-externally encoded objects. The results of this experiment suggest that processing information in relation to the self leads to a mnemonic benefit for source level features, and that activity in the medial prefrontal cortex contributes to this source memory benefit. This evidence expands the purported role that the medial prefrontal cortex plays in self-referencing. PMID:21936739

Source memory that encoding was self-referential: the influence of stimulus characteristics.

PubMed

Durbin, Kelly A; Mitchell, Karen J; Johnson, Marcia K

2017-10-01

Decades of research suggest that encoding information with respect to the self improves memory (self-reference effect, SRE) for items (item SRE). The current study focused on how processing information in reference to the self affects source memory for whether an item was self-referentially processed (a source SRE). Participants self-referentially or non-self-referentially encoded words (Experiment 1) or pictures (Experiment 2) that varied in valence (positive, negative, neutral). Relative to non-self-referential processing, self-referential processing enhanced item recognition for all stimulus types (an item SRE), but it only enhanced source memory for positive words (a source SRE). In fact, source memory for negative and neutral pictures was worse for items processed self-referentially than non-self-referentially. Together, the results suggest that item SRE and source SRE (e.g., remembering an item was encoded self-referentially) are not necessarily the same across stimulus types (e.g., words, pictures; positive, negative). While an item SRE may depend on the overall likelihood the item generates any association, the enhancing effects of self-referential processing on source memory for self-referential encoding may depend on how embedded a stimulus becomes in one's self-schema, and that depends, in part, on the stimulus' valence and format. Self-relevance ratings during encoding provide converging evidence for this interpretation.

Generation of Single Photons and Entangled Photon Pairs from a Quantum Dot

NASA Astrophysics Data System (ADS)

Yamamoto, Y.; Pelton, M.; Santori, C.; Solomon, G. S.

2002-10-01

Current quantum cryptography systems are limited by the Poissonian photon statistics of a standard light source: a security loophole is opened up by the possibility of multiple-photon pulses. By replacing the source with a single-photon emitter, transmission rates of secure information can be improved. A single photon source is also essential to implement a linear optics quantum computer. We have investigated the use of single self-assembled InAs/GaAs quantum dots as such single-photon sources, and have seen a hundred-fold reduction in the multi-photon probability as compared to Poissonian pulses. An extension of our experiment should also allow for the generation of triggered, polarizationentangled photon pairs.

Signal information available for plume source tracking with and without surface waves and learning by undergraduates assisting with the research

NASA Astrophysics Data System (ADS)

Wiley, Megan Beth

Autonomous vehicles have had limited success in locating point sources of pollutants, chemicals, and other passive scalars. However, animals such as stomatopods, a mantis shrimp, track odor plumes easily for food, mates, and habitat. Laboratory experiments using Planar Laser Induced Fluorescence measured odor concentration downstream of a diffusive source with and without live stomatopods to investigate their source-tracking strategies in unidirectional and "wave-affected" (surface waves with a mean current) flows. Despite the dearth of signal, extreme temporal variation, and meandering plume centerline, the stomatopods were able to locate the source, especially in the wave-affected flow. Differences in the two plumes far from the source (>160 cm) appeared to help the animals in the wave-affected flow position themselves closer to the source (<70 cm) at times with relatively large amounts of odor and plume filaments of high concentration. At the height of the animals' antennules, the site of their primary chemosensors, the time-averaged Reynolds stresses in the two flows were approximately the same. The temporal variation in stresses over the wave cycle may be responsible for differences in the two plumes. The antennule height falls between a region of large peaks in Reynolds stress in phase with peaks in streamwise acceleration, and a lower region with a smaller Reynolds stress peak in phase with maximum shear during flow reversal. Six undergraduate students assisted with the research. We documented their daily activities and ideas on plume dispersion using open-ended interviews. Most of their time was spent on tasks that required no understanding of fluid mechanics, and there was little evidence of learning by participation in the RAship. One RA's conceptions of turbulence did change, but a group workshop seemed to support this learning more than the RAship. The documented conceptions could aid in curriculum design, since situating new information within current knowledge seems to deepen learning outcomes. The RAs' conceptions varied widely with some overlap of ideas. The interviews also showed that most RAs did not discuss molecular diffusion as part of the mixing process and some remembered information from course demonstrations, but applied them inappropriately to the interview questions.

The STEP (Safety and Toxicity of Excipients for Paediatrics) database: part 2 - the pilot version.

2013-11-30

The screening and careful selection of excipients is a critical step in paediatric formulation development as certain excipients acceptable in adult formulations, may not be appropriate for paediatric use. While there is extensive toxicity data that could help in better understanding and highlighting the gaps in toxicity studies, the data are often scattered around the information sources and saddled with incompatible data types and formats. This paper is the second in a series that presents the update on the Safety and Toxicity of Excipients for Paediatrics ("STEP") database being developed by Eu-US PFIs, and describes the architecture data fields and functions of the database. The STEP database is a user designed resource that compiles the safety and toxicity data of excipients that is scattered over various sources and presents it in one freely accessible source. Currently, in the pilot database data from over 2000 references/10 excipients presenting preclinical, clinical, regulatory information and toxicological reviews, with references and source links. The STEP database allows searching "FOR" excipients and "BY" excipients. This dual nature of the STEP database, in which toxicity and safety information can be searched in both directions, makes it unique from existing sources. If the pilot is successful, the aim is to increase the number of excipients in the existing database so that a database large enough to be of practical research use will be available. It is anticipated that this source will prove to be a useful platform for data management and data exchange of excipient safety information. Copyright © 2013 Elsevier B.V. All rights reserved.

Adaptive interface for personalizing information seeking.

2004-12-01

An adaptive interface autonomously adjusts its display and available actions to current goals and abilities of the user by assessing user status, system task, and the context. Knowledge content adaptability is needed for knowledge acquisition and refinement tasks. In the case of knowledge content adaptability, the requirements of interface design focus on the elicitation of information from the user and the refinement of information based on patterns of interaction. In such cases, the emphasis on adaptability is on facilitating information search and knowledge discovery. In this article, we present research on adaptive interfaces that facilitates personalized information seeking from a large data warehouse. The resulting proof-of-concept system, called source recommendation system (SRS), assists users in locating and navigating data sources in the repository. Based on the initial user query and an analysis of the content of the search results, the SRS system generates a profile of the user tailored to the individual's context during information seeking. The user profiles are refined successively and are used in progressively guiding the user to the appropriate set of sources within the knowledge base. The SRS system is implemented as an Internet browser plug-in to provide a seamless and unobtrusive, personalized experience to the users during the information search process. The rationale behind our approach, system design, empirical evaluation, and implications for research on adaptive interfaces are described in this paper.

This report presents 1990 freshwater withdrawal estimates for Oklahoma by source and category. Withdrawal source is either ground water or surface water. Withdrawal categories include: irrigation, water supply, livestock, thermoelectric-power generation, domestic and commercial, and industrial and mining. Withdrawal data are aggregated by county, major aquifer, and principal river basin. Only the four major categories of irrigation, water supply, livestock, and thermoelectric-power generation are illustrated in this report, although data for all categories are tabulated. The U.S. Geological Survey (USGS) established the National Water-Use Information Program in 1977 to collect uniform, current, and reliable information on water use. The Oklahoma District of the USGS and the Oklahoma Water Resources Board participate in a cooperative program to collect and publish water-use information for Oklahoma. Data contained in this report were made available through the cooperative program.

Out-of-date or incomplete drug product labeling information may increase the risk of otherwise preventable adverse drug events. In recognition of these concerns, the United States Federal Drug Administration (FDA) requires drug product labels to include specific information. Unfortunately, several studies have found that drug product labeling fails to keep current with the scientific literature. We present a novel approach to addressing this issue. The primary goal of this novel approach is to better meet the information needs of persons who consult the drug product label for information on a drug's efficacy, effectiveness, and safety. Using FDA product label regulations as a guide, the approach links drug claims present in drug information sources available on the Semantic Web with specific product label sections. Here we report on pilot work that establishes the baseline performance characteristics of a proof-of-concept system implementing the novel approach. Claims from three drug information sources were linked to the Clinical Studies, Drug Interactions, and Clinical Pharmacology sections of the labels for drug products that contain one of 29 psychotropic drugs. The resulting Linked Data set maps 409 efficacy/effectiveness study results, 784 drug-drug interactions, and 112 metabolic pathway assertions derived from three clinically-oriented drug information sources (ClinicalTrials.gov, the National Drug File - Reference Terminology, and the Drug Interaction Knowledge Base) to the sections of 1,102 product labels. Proof-of-concept web pages were created for all 1,102 drug product labels that demonstrate one possible approach to presenting information that dynamically enhances drug product labeling. We found that approximately one in five efficacy/effectiveness claims were relevant to the Clinical Studies section of a psychotropic drug product, with most relevant claims providing new information. We also identified several cases where all of the drug-drug interaction claims linked to the Drug Interactions section for a drug were potentially novel. The baseline performance characteristics of the proof-of-concept will enable further technical and user-centered research on robust methods for scaling the approach to the many thousands of product labels currently on the market.

The functional food industry has experienced innovative and economic expansion, yet research into consumer perceptions of functional foods and their associated health claims is limited. Among consumers, older adults could benefit from functional foods due to age-related issues pertaining to food and health. The purpose of this research was to identify the need for information related to functional foods among older adults (≥60 years old) and to assess awareness and perceptions of health claims on functional food packages. Community-dwelling older adults (n = 200) completed a researcher administered questionnaire designed to collect information about functional foods including current consumption, motivating factors for consumption, perceived need for information, sources of information for functional foods and awareness of health claims. Prevalence of functional food consumption among participants was 93.0%. Increased awareness and knowledge was the most commonly reported factor that would promote functional food consumption (85.5%) and 63.5% of participants wanted more information about functional foods with preferred sources being newspapers/magazines/books (68.5%) and food labels (66.1%). Participants were predominately (93.5%) aware of health claims on functional foods and those with more education were more likely to report being aware of health claims (p = 0.045). Although functional food consumption among older adults in this sample is high, there is a need for further information regarding functional foods. These results inform stakeholders regarding the potential for information to influence functional food acceptance among older adult consumers.

The current study reports findings from evaluation research conducted to identify how online prostate cancer treatment decision-making information can be both improved and more effectively disseminated to those who need it most. A multi-method, multi-target approach was used and guided by McGuire's Communication Matrix Model. Focus groups (n = 31) with prostate cancer patients and their family members, and in-depth interviews with physicians (n = 8), helped inform a web survey (n = 89). Results indicated that physicians remain a key information source for medical advice and the Internet is a primary channel used to help make informed prostate cancer treatment decisions. Participants reported a need for more accessible information related to treatment options and treatment side effects. Additionally, physicians indicated that the best way for agencies to reach them with new information to deliver to patients is by contacting them directly and meeting with them one-on-one. Advice for organizations to improve their current prostate cancer web offerings and further ways to improve information dissemination are discussed.

Multi-source and ontology-based retrieval engine for maize mutant phenotypes

Model Organism Databases, including the various plant genome databases, collect and enable access to massive amounts of heterogeneous information, including sequence data, gene product information, images of mutant phenotypes, etc, as well as textual descriptions of many of these entities. While a variety of basic browsing and search capabilities are available to allow researchers to query and peruse the names and attributes of phenotypic data, next-generation search mechanisms that allow querying and ranking of text descriptions are much less common. In addition, the plant community needs an innovative way to leverage the existing links in these databases to search groups of text descriptions simultaneously. Furthermore, though much time and effort have been afforded to the development of plant-related ontologies, the knowledge embedded in these ontologies remains largely unused in available plant search mechanisms. Addressing these issues, we have developed a unique search engine for mutant phenotypes from MaizeGDB. This advanced search mechanism integrates various text description sources in MaizeGDB to aid a user in retrieving desired mutant phenotype information. Currently, descriptions of mutant phenotypes, loci and gene products are utilized collectively for each search, though expansion of the search mechanism to include other sources is straightforward. The retrieval engine, to our knowledge, is the first engine to exploit the content and structure of available domain ontologies, currently the Plant and Gene Ontologies, to expand and enrich retrieval results in major plant genomic databases.

We characterize the geometrical and electrical characteristics of the initial stages of nine Florida triggered lightning discharges using a Lightning Mapping Array (LMA), a C-band SMART radar, and measured channel-base currents. We determine initial channel and subsequent branch lengths, average initial channel and branch propagation speeds, and channel-base current at the time of each branch initiation. The channel-base current is found to not change significantly when branching occurs, an unexpected result. The initial stage of Florida triggered lightning typically transitions from vertical to horizontal propagation at altitudes of 3-6 km, near the typical 0 C level of 4-5 km and several kilometers below the expected center of the negative cloud-charge region at 7-8 km. The data presented potentially provide information on thunderstorm electrical and hydrometeor structure and discharge propagation physics. LMA source locations were obtained from VHF sources of positive impulsive currents as small as 10 A, in contrast to expectations found in the literature.

A NEW METHOD FOR FINDING POINT SOURCES IN HIGH-ENERGY NEUTRINO DATA

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

Fang, Ke; Miller, M. Coleman

The IceCube collaboration has reported the first detection of high-energy astrophysical neutrinos, including ∼50 high-energy starting events, but no individual sources have been identified. It is therefore important to develop the most sensitive and efficient possible algorithms to identify the point sources of these neutrinos. The most popular current method works by exploring a dense grid of possible directions to individual sources, and identifying the single direction with the maximum probability of having produced multiple detected neutrinos. This method has numerous strengths, but it is computationally intensive and because it focuses on the single best location for a point source,more » additional point sources are not included in the evidence. We propose a new maximum likelihood method that uses the angular separations between all pairs of neutrinos in the data. Unlike existing autocorrelation methods for this type of analysis, which also use angular separations between neutrino pairs, our method incorporates information about the point-spread function and can identify individual point sources. We find that if the angular resolution is a few degrees or better, then this approach reduces both false positive and false negative errors compared to the current method, and is also more computationally efficient up to, potentially, hundreds of thousands of detected neutrinos.« less

Rose, India D; Friedman, Daniela B

Young men who have sex with men (YMSM) have unique health concerns, including high rates of HIV infection. To prevent HIV, YMSM need credible information from trusted sources, specifically parents. Little is known about what health information resources parents of YMSM need to communicate with their child about HIV prevention. The primary objective of this study was to examine the proxy health information seeking behaviours of parents of YMSM and to identify information resources that parents need to communicate with their YMSM identified child about HIV prevention. Qualitative findings were grouped into four categories: parents' current health information sources; barriers to seeking health information; parents' health information needs; and recommendations for delivery of health information for parents. Ten in-depth interviews were conducted with parents of YMSM. Parents reported consulting physicians and the Internet for HIV/AIDS information. They reported finding limited information targeted towards parents of YMSM and provided suggestions for improving the delivery of health information including training, websites and the local news. Delivery of tailored HIV prevention information to parents may be effective in helping combat HIV among YMSM. Given that YMSM bear the greatest burden for HIV, this study highlights the need to include parents of YMSM in future interventions aimed at reducing YMSM's risk of HIV/AIDS. © 2016 Health Libraries Group.

Purchasing online journal access for a hospital medical library: how to identify value in commercially available products.

Carter, Thomas P; Carter, Anne O; Broomes, Gwendolyn

2006-07-12

Medical practice today requires evaluating large amounts of information which should be available at all times. This information is found most easily in a digital form. Some information has already been evaluated for validity (evidence based medicine sources) and some is in unevaluated form (paper and online journals). In order to improve access to digital information, the School of Clinical Medicine and Research at the University of the West Indies and Queen Elizabeth Hospital decided to enhance the library by offering online full text medical articles and evidence based medicine sources. The aim of this paper is to evaluate the relative value of online journal commercial products available for a small hospital and medical school library. Three reference standards were chosen to represent the ideal list of core periodicals for a broad range of medical care: 2 Brandon/Hill selected lists of journals for the small medical library (BH and BH core) and the academic medical library core journal collection chosen for the Florida State University College of Medicine Medical Library. Six commercially available collections were compared to the reference standards and to the current paper journal subscription list as regards to number of journals matched and cost per journal matched. Ease of use and presence of secondary sources were also considered. The cost per journal matched ranged from US $3194 to $81. Because of their low subscription prices, the Biomedical Reference Collection and Proquest products were the most cost beneficial. However, they provided low coverage of the ideal lists (12-17% and 21-32% respectively) and contained significant embargoes on current editions, were not user friendly and contained no secondary sources. The Ovid Brandon/Hill Plus Collection overcame these difficulties but had a much higher cost-benefit range while providing higher coverage of the ideal lists (14-47%). After considering costs, benefits, ease of use, embargoes, presence of secondary sources (ACP Journal Club, DARE), the Ovid Brandon/Hill Plus Collection was the best choice for our hospital considering our budget. However, the option to individually select our own journal list from Ovid and pay per journal has a certain appeal as well.

Information and post-sedation arrangements are important to patients'safety following surgery but although there is a general consensus over what is recommended for patients and their escorts, there is little, if any, literature on the escorts' awareness of sedation and accordance to post-sedation arrangement and recommendations. Escorts of 113 consecutive patients treated in oral surgery under sedation (midazolam) completed a questionnaire composed of 27 questions divided into seven sections including demographics, awareness of sedation, source of information and post-operative arrangement. From the data collected, two scores were calculated representative of the escorts' Safety and Reliability. Data were then analysed by ANOVA. Safety scores were statistically correlated with instruction source while Reliability correlated to a wider variety of parameters including gender, age as well as information source. Provision of clear written information to escorts is recommended as likely to improve patients' safety. Assessment of escorts' Safety and Reliability could provide a means for improving quality and safety of sedation service.

Optical Characteristics of Astrometric Radio Sources OCARS

NASA Astrophysics Data System (ADS)

Malkin, Z.

2013-04-01

In this paper, the current status of the catalog of Optical Characteristics of Astrometric Radio Sources OCARS is presented. The catalog includes radio sources observed in various astrometric and geodetic VLBI programs in 1979-2012. For these sources the physical object type, redshift and visual or infrared magnitude is given when available. Detailed comments are provided when some problems with published data were encountered. Since the first version created in December 2007, the catalog is continuously developed and expanded in respect to inclusion of new radio sources and addition of new or correction of old astrophysical data. Several sources of information are used for OCARS. The main of them are the NASA/IPAC Extragalactic Database (NED) and SIMBAD astronomical databases. Besides several astronomical journals and arXiv depository are regularly monitored, so that new data is included in OCARS just after publication. The redshift for about 150 sources have been determined from dedicated optical spectroscopic observations. As of October 2012, OCARS catalog includes 7173 radio sources. 3898 sources have known redshift, and 4860 sources have known magnitude. In 2009, it was used as a supplement material to the ICRF2. The list of radio sources with a good observational history but lacking astrophysical information is provide for planning of optical observations of the most important astrometric sources. The OCARS catalog is updated, in average every several weeks and is available at http://www.gao.spb.ru/english/as/ac_vlbi/ocars.txt.

Distribution System Upgrade Unit Cost Database

DOE Data Explorer

Horowitz, Kelsey

2017-11-30

This database contains unit cost information for different components that may be used to integrate distributed photovotaic (D-PV) systems onto distribution systems. Some of these upgrades and costs may also apply to integration of other distributed energy resources (DER). Which components are required, and how many of each, is system-specific and should be determined by analyzing the effects of distributed PV at a given penetration level on the circuit of interest in combination with engineering assessments on the efficacy of different solutions to increase the ability of the circuit to host additional PV as desired. The current state of the distribution system should always be considered in these types of analysis. The data in this database was collected from a variety of utilities, PV developers, technology vendors, and published research reports. Where possible, we have included information on the source of each data point and relevant notes. In some cases where data provided is sensitive or proprietary, we were not able to specify the source, but provide other information that may be useful to the user (e.g. year, location where equipment was installed). NREL has carefully reviewed these sources prior to inclusion in this database. Additional information about the database, data sources, and assumptions is included in the "Unit_cost_database_guide.doc" file included in this submission. This guide provides important information on what costs are included in each entry. Please refer to this guide before using the unit cost database for any purpose.

Despite well known risks associated with unprotected premarital sex, this phenomenon has not been well explored among young men in rural northern Nigeria. We studied the predictors of premarital sex and preferred sources of sexual and reproductive health information among young unmarried men in Kumbotso, northern Nigeria. A cross section of 400 young men were interviewed using structured questionnaires with mostly closed ended questions. Of the 385 respondents, 39 (10.1%) were sexually experienced. Less than half of respondents (48.7%) used a condom at sexual debut, and an equal proportion reported having multiple sex partners. Only 41.0% of sexually experienced respondents reported subsequent consistent condom use Age (adjusted odds ratio [AOR] = 4.12; 95% confidence interval (CI): 2.24-5.20 and educational attainment [AOR = 3.57; 95% CI (1.49-9.10)] were significant predictors of sexual experience. The current versus preferred sources of sexual and reproductive health information included friends (51.3% vs. 93.3%), Islamic school teachers (41.0% vs. 72.7%) and school teachers (8.8% vs. 15.1%). Although the prevalence of premarital sex among young men in this community in northern Nigeria as low, those that did engage in such activity were likely to not use condoms and to have multiple partners. Preferred and trusted sources of information included peers and religious leaders. The findings in this study could be used to develop innovative strategies for reaching young men with accurate sexual and reproductive health information.

Information and research needs of acute-care clinical nurses.

PubMed Central

Spath, M; Buttlar, L

1996-01-01

The majority of nurses surveyed used the library on a regular but limited basis to obtain information needed in caring for or making decisions about their patients. A minority indicated that the libraries in their own institutions totally met their information needs. In fact, only 4% depended on the library to stay abreast of new information and developments in the field. Many of the nurses had their own journal subscriptions, which could account in part for the limited use of libraries and the popularity of the professional journal as the key information source. This finding correlates with the research of Binger and Huntsman, who found that 95% of staff development educators relied on professional journal literature to keep up with current information in the field, and only 45% regularly monitored indexing-and-abstracting services. The present study also revealed that nurses seek information from colleagues more than from any other source, supporting the findings of Corcoran-Perry and Graves. Further research is necessary to clarify why nurses use libraries on a limited basis. It appears, as Bunyan and Lutz contend, that a more aggressive approach to marketing the library to nurses is needed. Further research should include an assessment of how the library can meet the information needs of nurses for both research and patient care. Options to be considered include offering library orientation sessions for new staff nurses, providing current-awareness services by circulating photocopied table-of-contents pages, sending out reviews of new monographs, inviting nurses to submit search requests on a topic, scheduling seminars and workshops that teach CD-ROM and online search strategies, and providing information about electronic databases covering topics related to nursing. Information on databases may be particularly important in light of the present study's finding that databases available in CD-ROM format are consulted very little. Nursing education programs should be expanded to include curricula bibliographic sessions where the librarian, in cooperation with the teaching faculty, visits the classroom to explain all pertinent information sources or invites the class to the library for hands-on demonstration and practice. Nurses who gain working knowledge of the tools that open the doors to retrieval of research findings and who have information about new innovations in medicine and medical technology have superior chances for success in their chosen profession.

Photonic sources and detectors for quantum information protocols: A trilogy in eight parts

NASA Astrophysics Data System (ADS)

Rangarajan, Radhika

Quantum information processing (QIP) promises to revolutionize existing methods of manipulating data, via truly unique paradigms based on fundamental nonclassical physical phenomenon. However, the eventual success of optical QIP depends critically on the available technologies. Currently, creating multiple-photon states is extremely inefficient because almost no source thus far has been well optimized. Additionally, high-efficiency single-photon detectors can drastically improve multi-photon QIP (typical efficiencies are ˜70%). In fact, it has been shown that scalable linear optical quantum computing is possible only if the product of the source and detector efficiencies exceeds ˜67%. The research presented here focuses on developing optimized source and detector technologies for enabling scalable QIP. The goal of our source research is to develop an ideal " indistinguishable" source of ultrabright polarization-entangled but spatially- and spectrally-unentangled photon pairs. We engineer such an ideal source by first designing spatio-spectrally unentangled photons using optimized and group-velocity matched spontaneous parametric down conversion (SPDC). Next, we generate polarization-entangled photons using the engineered SPDC. Here we present solutions to the various challenges encountered during the indistinguishable source development. We demonstrate high-fidelity ultrafast pulsed and cw-diode laser-pumped sources of polarization-entangled photons, as well as the first production of polarization-entanglement directly from the highly nonlinear biaxial crystal BiB3O6 (BiBO). We also discuss the first experimental confirmation of the emission-angle dependence of the downconversion polarization (the Migdall effect), and a novel scheme for polarization-dependent focusing. The goal of our single-photon detector research is to develop a very high-efficiency detection system that can also resolve incident photon number, a feature absent from the typical detectors employed for QIP. We discuss the various cryogenic, optical and electronic challenges encountered en route to detector development and present details on detector characterization, ultra-short electronics design and photon-number-resolution studies. The source and detector technologies developed here share a common goal: to enhance the efficiency of existing quantum protocols and pave the way for new ones. Here we discuss some of the possible benefits via a popular quantum protocol---teleportation---as well as a novel quantum communication technique---hyper-fingerprinting. Taken as a whole, this dissertation explores viable technological options for enhancing optical quantum information protocols, offers a perspective on the current status and limitations of existing technologies, and highlights the possibilities enabled by optimized photonic sources and detectors.

Misplaced Trust: Racial Differences in Use of Tobacco Products and Trust in Sources of Tobacco Health Information.

PubMed

Alcalá, Héctor E; Sharif, Mienah Z; Morey, Brittany N

2017-10-01

Recently, the rates of utilization of alternative tobacco products have increased. Providing health information about tobacco products from trustworthy sources may help decrease the popularity of these products. Using a nationally representative study of adults, we fill the current gap in research on racial and ethnic disparities in utilization of alternative tobacco products as well as in trust of sources of health information about tobacco products. Data came from the Health Information National Trends Survey (N = 3738), which was collected in 2015. Logistic regression models were used to calculate odds of use of seven different tobacco product (eg, hookah, e-cigarettes, etc.), trust in seven different sources of e-cigarette health information (eg, family or friends, health care providers, etc.), and trust in six different sources of tobacco health information, adjusting for control variables. There were disparities in utilization of alternative tobacco products and in trust, in tobacco companies across racial and ethnic groups. Blacks and Asians were far more likely than whites to trust tobacco (adjusted odds ratios = 8.67 and 4.34) and e-cigarette companies (adjusted odds ratios = 6.97 and 3.13) with information about the health effects of e-cigarettes than whites. The popularity of alternative tobacco products appears to be high and may offset recent observed decreases in cigarette use. Blacks and Asians appear to trust tobacco companies as sources of information when compared to whites. Higher levels of trust in tobacco companies among Asians and blacks may translate to greater susceptibility to utilize tobacco products among these groups, thereby increasing disparities. There is a need for social marketing and education efforts focused on increasing awareness of adverse health effects of using alternative tobacco products as well as on the untrustworthiness of tobacco and e-cigarette companies, especially among racial and ethnic minorities. © The Author 2017.

2017-12-01

Cu pollution in marine bays has been one of the critical environmental issues in the whole world, and understanding the variations of the pollution sources is essential to environmental protection. This paper identified the sources of Cu in Jiaozhou Bay during 1982-1986, and revealed the variations of the sources. Results showed that there were five Cu sources during study years including marine current, stream flow, island top, overland runoff and marine traffic, respectively, whose source strengths were varying from 0.39-20.60 μg L-1, 0.37-10.57 μg L-1, 0.77-4.86 μg L-1, 2.28-3.56 μg L-1, 9.48 μg L-1, respectively. These findings were helpful information in decision-making of pollution control and environmental remediation practice.

New threats to health data privacy.

PubMed

Li, Fengjun; Zou, Xukai; Liu, Peng; Chen, Jake Y

2011-11-24

Along with the rapid digitalization of health data (e.g. Electronic Health Records), there is an increasing concern on maintaining data privacy while garnering the benefits, especially when the data are required to be published for secondary use. Most of the current research on protecting health data privacy is centered around data de-identification and data anonymization, which removes the identifiable information from the published health data to prevent an adversary from reasoning about the privacy of the patients. However, published health data is not the only source that the adversaries can count on: with a large amount of information that people voluntarily share on the Web, sophisticated attacks that join disparate information pieces from multiple sources against health data privacy become practical. Limited efforts have been devoted to studying these attacks yet. We study how patient privacy could be compromised with the help of today's information technologies. In particular, we show that private healthcare information could be collected by aggregating and associating disparate pieces of information from multiple online data sources including online social networks, public records and search engine results. We demonstrate a real-world case study to show user identity and privacy are highly vulnerable to the attribution, inference and aggregation attacks. We also show that people are highly identifiable to adversaries even with inaccurate information pieces about the target, with real data analysis. We claim that too much information has been made available electronic and available online that people are very vulnerable without effective privacy protection.

In their own words: A qualitative study exploring influences on the food choices of university students.

Lambert, Michelle; Chivers, Paola; Farringdon, Fiona

2018-06-11

University students generally make independent decisions regarding food choices. Current research about knowledge of Australian Dietary Guidelines (ADG), sources of nutrition information and influences on food choices for this group is scarce. Qualitative data was collected from gender separated focus groups comprising four female (n=31) and four male (n=18) to identify: knowledge of ADG, sources of nutrition information; factors that influence food choices; perceived relevant nutrition messages and how best to deliver them. Gaps in knowledge were identified particularly regarding number of serves and serving size for food groups. Social media was the most commonly reported source of knowledge. Social media was also a major influence on food choice due to its impact on body ideals. Current health promotion nutrition messages were perceived irrelevant given the focus on long-term health risks. Health and adhering to the ADG were not identified as important. The desire to look a particular way was the major influence on food choices. SO WHAT?: While there is an awareness of ADG, our participants made a deliberate decision not to follow them. This provides a challenge for developing relevant preventive health messages for this target audience. This article is protected by copyright. All rights reserved.

How Do Patients Choose Physicians? Evidence from a National Survey of Enrollees in Employment-Related Health Plans

PubMed Central

Harris, Katherine M

2003-01-01

Objective This study examines the process by which patients search for and choose physicians. Data Source A survey to a random sample of individuals between the ages of 21 and 64 with employer-related health benefits, drawn from a nationally representative panel of households. Study Design Logit models are used to measure the effect of patient characteristics on the probability of (1) using alternative sources of information to support the choice of a current physician, (2) seriously considering another physician before choosing a current physician, and (3) stating a willingness to switch physicians when information suggests that other health plan doctors receive higher quality ratings. Principal Findings Although a minority of respondents actively searches for a physician, there appears to be substantial variation in the degree of consumer activism across patient subgroups. Poor health status, higher levels of service use in the past year, and stronger ties to individual physicians are associated with less consumer activism. At the same time, greater levels of consumer activism were found among racial and ethnic minorities, among those who report using information to choose their physicians, and among those who switched physicians as a result of dissatisfaction some time in the past five years. Source of quality information (medical experts versus patient advocates) did not influence stated willingness to switch physicians. Conclusions Despite predictions of the increasing importance of consumer choice in shaping the health care delivery system, the results largely confirm the image depicted in the previous literature of patients as passive health care consumers of physician services, and highlight the importance of investments in the development of decision support tools in consumer-driven health care systems.

The present study investigated whether, when performing a WM task, high- and low-span individuals differ in the activation of formerly relevant, but now irrelevant items, and/or in their ability to correctly identify such irrelevant items. This was done in two experiments, both of which used modified complex WM span tasks. In Experiment 1, the span task included an embedded lexical decision task designed to obtain an implicit measure of the activation of both currently and formerly relevant items. In Experiment 2, the span task included an embedded recognition judgment task designed to obtain an explicit measure of both item and source recognition ability. The results of these experiments indicate that low-span individuals do not hold irrelevant information in a more active state in memory than high-span individuals, but rather that low-span individuals are significantly poorer at identifying such information as irrelevant at the time of retrieval. These results suggest that differences in the ability to monitor the source of information, rather than differences in the activation of irrelevant information, are the more important determinant of performance on WM tasks.

Current infrastructure research in PACS is dominated by the development of communication networks (local area networks, teleradiology, ATM networks, etc.), multimedia display workstations, and hierarchical image storage architectures. However, limited work has been performed on developing flexible, expansible, and intelligent information processing architectures for the vast decentralized image and text data repositories prevalent in healthcare environments. Patient information is often distributed among multiple data management systems. Current large-scale efforts to integrate medical information and knowledge sources have been costly with limited retrieval functionality. Software integration strategies to unify distributed data and knowledge sources is still lacking commercially. Systems heterogeneity (i.e., differences in hardware platforms, communication protocols, database management software, nomenclature, etc.) is at the heart of the problem and is unlikely to be standardized in the near future. In this paper, we demonstrate the use of newly available CASE (computer- aided software engineering) tools to rapidly integrate HIS, RIS, and PACS information systems. The advantages of these tools include fast development time (low-level code is generated from graphical specifications), and easy system maintenance (excellent documentation, easy to perform changes, and centralized code repository in an object-oriented database). The CASE tools are used to develop and manage the `middle-ware' in our client- mediator-serve architecture for systems integration. Our architecture is scalable and can accommodate heterogeneous database and communication protocols.

Exploring the costs and benefits of social information use: an appraisal of current experimental evidence.

Research on social learning has focused traditionally on whether animals possess the cognitive ability to learn novel motor patterns from tutors. More recently, social learning has included the use of others as sources of inadvertent social information. This type of social learning seems more taxonomically widespread and its use can more readily be approached as an economic decision. Social sampling information, however, can be tricky to use and calls for a more lucid appraisal of its costs. In this four-part review, we address these costs. Firstly, we address the possibility that only a fraction of group members are actually providing social information at any one time. Secondly, we review experimental research which shows that animals are circumspect about social information use. Thirdly, we consider the cases where social information can lead to incorrect decisions and finally, we review studies investigating the effect of social information quality. We address the possibility that using social information or not is not a binary decision and present results of a study showing that nutmeg mannikins combine both sources of information, a condition that can lead to the establishment of informational cascades. We discuss the importance of empirically investigating the economics of social information use.

Characterization of particulate emissions from Australian open-cut coal mines: Toward improved emission estimates.

Given the significance of mining as a source of particulates, accurate characterization of emissions is important for the development of appropriate emission estimation techniques for use in modeling predictions and to inform regulatory decisions. The currently available emission estimation methods for Australian open-cut coal mines relate primarily to total suspended particulates and PM 10 (particulate matter with an aerodynamic diameter <10 μm), and limited data are available relating to the PM 2.5 (<2.5 μm) size fraction. To provide an initial analysis of the appropriateness of the currently available emission estimation techniques, this paper presents results of sampling completed at three open-cut coal mines in Australia. The monitoring data demonstrate that the particulate size fraction varies for different mining activities, and that the region in which the mine is located influences the characteristics of the particulates emitted to the atmosphere. The proportion of fine particulates in the sample increased with distance from the source, with the coarse fraction being a more significant proportion of total suspended particulates close to the source of emissions. In terms of particulate composition, the results demonstrate that the particulate emissions are predominantly sourced from naturally occurring geological material, and coal comprises less than 13% of the overall emissions. The size fractionation exhibited by the sampling data sets is similar to that adopted in current Australian emission estimation methods but differs from the size fractionation presented in the U.S. Environmental Protection Agency methodology. Development of region-specific emission estimation techniques for PM 10 and PM 2.5 from open-cut coal mines is necessary to allow accurate prediction of particulate emissions to inform regulatory decisions and for use in modeling predictions. Development of region-specific emission estimation techniques for PM 10 and PM 2.5 from open-cut coal mines is necessary to allow accurate prediction of particulate emissions to inform regulatory decisions and for use in modeling predictions.

Shen, Terry H; Carlson, Christopher S; Tarczy-Hornoch, Peter

2009-08-01

Genome wide association studies can potentially identify the genetic causes behind the majority of human diseases. With the advent of more advanced genotyping techniques, there is now an explosion of data gathered on single nucleotide polymorphisms (SNPs). The need exists for an integrated system that can provide up-to-date functional annotation information on SNPs. We have developed the SNP Integration Tool (SNPit) system to address this need. Built upon a federated data integration system, SNPit provides current information on a comprehensive list of SNP data sources. Additional logical inference analysis was included through an inference engine plug in. The SNPit web servlet is available online for use. SNPit allows users to go to one source for up-to-date information on the functional annotation of SNPs. A tool that can help to integrate and analyze the potential functional significance of SNPs is important for understanding the results from genome wide association studies.

Sources of information for assessing human papillomavirus vaccination history among young women.

Assessing history of human papillomavirus (HPV) vaccination is important for monitoring vaccine uptake, impact, and effectiveness. Based on data collected from 1720 women with high-grade cervical lesions reported to a statewide surveillance system in Connecticut, we found that available medical records did not contain HPV vaccination information for 34% of women, and 43% of women could not be reached for interview. When both were used for data collection, concordance of vaccination history (83%) and sensitivity of self-report (96%) were both high. Reviewing medical records based on self-reported information about vaccine providers increased confirmation of vaccination histories in this sample by 18%. The vaccine registry in Connecticut is not currently utilized for HPV vaccinations, but efforts to increase use for adolescent vaccines could be useful in the future to overcome limitations of other sources.

ChemAgora, a web application designed and developed in the context of the "Data Infrastructure for Chemical Safety Assessment" (diXa) project, provides search capabilities to chemical data from resources available online, enabling users to cross-reference their search results with both regulatory chemical information and public chemical databases. ChemAgora, through an on-the-fly search, informs whether a chemical is known or not in each of the external data sources and provides clikable links leading to the third-party web site pages containing the information. The original purpose of the ChemAgora application was to correlate studies stored in the diXa data warehouse with available chemical data. Since the end of the diXa project, ChemAgora has evolved into an independent portal, currently accessible directly through the ChemAgora home page, with improved search capabilities of online data sources.

In the USA, recent changes to oversight of residency training codify the requirements for teaching evidence-based medicine and information mastery (lifelong learning) knowledge, skills, and attitudes. The goal of this project is to determine current requirements for teaching of evidence-based medicine (EBM) and information mastery (IM) in specialty residency education in the USA. The project was a qualitative thematic analysis using content analysis. The source of the requirements for EBM and IM were the "milestone" statements for all 28 major specialties and transition year programs. Milestone descriptors related to EBM/IM were extracted and codes were developed and applied to each descriptor by four researchers. The resulting codes were coalesced into themes and tested against the milestone descriptors. The coding process identified 15 content areas comprising five themes. Two themes related to the knowledge and skills of EBM and three themes related to the knowledge, skills, and attitudes of IM. EBM themes encompassed basic critical appraisal skills and knowledge of clinical epidemiology principles and statistics. IM themes centered on identifying one's information needs for patient-specific information, using information sources, and using current awareness services to remain abreast of changes in medicine. In general, they align well with the Sicily Statement on Evidence-Based Practice. No specialty required competence in all areas. New training requirements for specialties in the USA require the development of both classic EBM skills as well as skills for managing information. However, there is marked variation in the requirements among specific specialties. © 2016 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

A large number of diverse, complex, and distributed data resources are currently available in the Bioinformatics domain. The pace of discovery and the diversity of information means that centralised reference databases like UniProt and Ensembl cannot integrate all potentially relevant information sources. From a user perspective however, centralised access to all relevant information concerning a specific query is essential. The Distributed Annotation System (DAS) defines a communication protocol to exchange annotations on genomic and protein sequences; this standardisation enables clients to retrieve data from a myriad of sources, thus offering centralised access to end-users. We introduce MyDas, a web server that facilitates the publishing of biological annotations according to the DAS specification. It deals with the common functionality requirements of making data available, while also providing an extension mechanism in order to implement the specifics of data store interaction. MyDas allows the user to define where the required information is located along with its structure, and is then responsible for the communication protocol details. PMID:23028496

Critical information literacy as core skill for lifelong STEM learning in the 21st century: reflections on the desirability and feasibility for widespread science media education

NASA Astrophysics Data System (ADS)

Storksdieck, Martin

2016-03-01

Grace Reid and the late Stephen Norris argue in this issue the urgent need for widespread Science Media Education (SME) as an integral part of formal and informal science education. SME is to achieve two goals: First, allow learners to critically evaluate any media as a source for scientific information by understanding the socio-economic and socio-cultural context of how and why news and entertainment media are created, and secondly, utilize media as a legitimate and productive source for science education and science learning. While laudable, I will argue that SME as an integral part of STEM education is unrealistic, and offer instead that the broader concept of Information Literacy might be more easily achieved within the current strong movement to conceptualize STEM education via science and engineering practices and within the broad goals of strengthening learners' 21st century skills.

1988-11-01

This paper reports the results of a review of second law analysis techniques which can contribute to basic research in the thermal sciences. The review demonstrated that second law analysis has a role in basic thermal science research. Unlike traditional techniques, second law analysis accurately identifies the sources and location of thermodynamic losses. This allows the development of innovative solutions to thermal science problems by directing research to the key technical issues. Two classes of second law techniques were identified as being particularly useful. First, system and component investigations can provide information of the source and nature of irreversibilities on a macroscopic scale. This information will help to identify new research topics and will support the evaluation of current research efforts. Second, the differential approach can provide information on the causes and spatial and temporal distribution of local irreversibilities. This information enhances the understanding of fluid mechanics, thermodynamics, and heat and mass transfer, and may suggest innovative methods for reducing irreversibilities.

The Windber Research Institute is an integrated high-throughput research center employing clinical, genomic and proteomic platforms to produce terabyte levels of data. We use biomedical informatics technologies to integrate all of these operations. This report includes information on a multi-year, multi-phase hybrid data warehouse project currently under development in the Institute. The purpose of the warehouse is to host the terabyte-level of internal experimentally generated data as well as data from public sources. We have previously reported on the phase I development, which integrated limited internal data sources and selected public databases. Currently, we are completing phase II development, which integrates our internal automated data sources and develops visualization tools to query across these data types. This paper summarizes our clinical and experimental operations, the data warehouse development, and the challenges we have faced. In phase III we plan to federate additional manual internal and public data sources and then to develop and adapt more data analysis and mining tools. We expect that the final implementation of the data warehouse will greatly facilitate biomedical informatics research.

The Role of Environmental Reservoirs in Human Campylobacteriosis

2013-01-01

Campylobacteriosis is infection caused by the bacteria Campylobacter spp. and is considered a major public health concern. Campylobacter spp. have been identified as one of the most common causative agents of bacterial gastroenteritis. They are typically considered a foodborne pathogen and have been shown to colonise the intestinal mucosa of all food-producing animals. Much emphasis has been placed on controlling the foodborne pathway of exposure, particularly within the poultry industry, however, other environmental sources have been identified as important contributors to human infection. This paper aims to review the current literature on the sources of human exposure to Campylobacter spp. and will cover contaminated poultry, red meat, unpasteurised milk, unwashed fruit and vegetables, compost, wild bird faeces, sewage, surface water, ground water and drinking water. A comparison of current Campylobacter spp. identification methods from environmental samples is also presented. The review of literature suggests that there are multiple and diverse sources for Campylobacter infection. Many environmental sources result in direct human exposure but also in contamination of the food processing industry. This review provides useful information for risk assessment. PMID:24217177

A surface ionization gauge (SIG) was constructed and used to measure the Cs/sup 0/ flow rate through the emission slit of a surface-plasma source (SPS) of H/sup -/ ions with Penning geometry. The equivalent cesium density in the SPS discharge is deduced from these flow measurements. For dc operation the optimum H/sup -/ current occurs at an equivalent cesium density of approx. 7 x 10/sup 12/ cm/sup -3/ (corresponding to an average cesium consumption rate of 0.5 mg/h). For pulsed operation the optimum H/sup -/ current occurs at an equivalent cesium density of approx. 2 x 10/sup 13/ cm/sup -3/more » (1-mg/h average cesium consumption rate). Cesium trapping by the SPS discharge was observed for both dc and pulsed operation. A cesium energy of approx. 0.1 eV is deduced from the observed time of flight to the SIG. In addition to providing information on the physics of the source, the SIG is a useful diagnostic tool for source startup and operation.« less

The effect of rate denominator source on US fatal occupational injury rate estimates.

PubMed

Richardson, David; Loomis, Dana; Bailer, A John; Bena, James

2004-09-01

The Current Population Survey (CPS) is often used as a source of denominator information for analyses of US fatal occupational injury rates. However, given the relatively small sample size of the CPS, analyses that examine the cross-classification of occupation or industry with demographic or geographic characteristics will often produce highly imprecise rate estimates. The Decennial Census of Population provides an alternative source for rate denominator information. We investigate the comparability of fatal injury rates derived using these two sources of rate denominator information. Information on fatal occupational injuries that occurred between January 1, 1983 and December 31, 1994 was obtained from the National Traumatic Occupational Fatality surveillance system. Annual estimates of employment by occupation, industry, age, and sex were derived from the CPS, and by linear interpolation and extrapolation from the 1980 and 1990 Census of Population. Fatal injury rates derived using these denominator data were compared. Fatal injury rates calculated using Census-based denominator data were within 10% of rates calculated using CPS data for all major occupation groups except farming/forestry/fishing, for which the fatal injury rate calculated using Census-based denominator data was 24.69/100,000 worker-years and the rate calculated using CPS data was 19.97/100,000 worker-years. The choice of denominator data source had minimal influence on estimates of trends over calendar time in the fatal injury rates for most major occupation and industry groups. The Census offers a reasonable source for deriving fatal injury rate denominator data in situations where the CPS does not provide sufficiently precise data, although the Census may underestimate the population-at-risk in some industries as a consequence of seasonal variation in employment.

Modernization and unification: Strategic goals for NASA STI program

Information is increasingly becoming a strategic resource in all societies and economies. The NASA Scientific and Technical Information (STI) Program has initiated a modernization program to address the strategic importance and changing characteristics of information. This modernization effort applies new technology to current processes to provide near-term benefits to the user. At the same time, we are developing a long-term modernization strategy designed to transition the program to a multimedia, global 'library without walls.' Notwithstanding this modernization program, it is recognized that no one information center can hope to collect all the relevant data. We see information and information systems changing and becoming more international in scope. We are finding that many nations are expending resources on national systems which duplicate each other. At the same time that this duplication exists, many useful sources of aerospace information are not being collected because of resource limitations. If nations cooperate to develop an international aerospace information system, resources can be used efficiently to cover expanded sources of information. We must consider forming a coalition to collect and provide access to disparate, multidisciplinary sources of information, and to develop standardized tools for documenting and manipulating this data and information. In view of recent technological developments in information science and technology, as well as the reality of scarce resources in all nations, it is time to explore the mutually beneficial possibilities offered by cooperation and international resource sharing. International resources need to be mobilized in a coordinated manner to move us towards this goal. This paper reviews the NASA modernization program and raises for consideration new possibilities for unification of the various aerospace database efforts toward a cooperative international aerospace database initiative that can optimize the cost/benefit equation for all participants.

Preliminary results concerning the simulation of beam profiles from extracted ion current distributions for mini-STRIKE

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

Agostinetti, P., E-mail: piero.agostinetti@igi.cnr.it; Serianni, G.; Veltri, P.

The Radio Frequency (RF) negative hydrogen ion source prototype has been chosen for the ITER neutral beam injectors due to its optimal performances and easier maintenance demonstrated at Max-Planck-Institut für Plasmaphysik, Garching in hydrogen and deuterium. One of the key information to better understand the operating behavior of the RF ion sources is the extracted negative ion current density distribution. This distribution—influenced by several factors like source geometry, particle drifts inside the source, cesium distribution, and layout of cesium ovens—is not straightforward to be evaluated. The main outcome of the present contribution is the development of a minimization method tomore » estimate the extracted current distribution using the footprint of the beam recorded with mini-STRIKE (Short-Time Retractable Instrumented Kalorimeter). To accomplish this, a series of four computational models have been set up, where the output of a model is the input of the following one. These models compute the optics of the ion beam, evaluate the distribution of the heat deposited on the mini-STRIKE diagnostic calorimeter, and finally give an estimate of the temperature distribution on the back of mini-STRIKE. Several iterations with different extracted current profiles are necessary to give an estimate of the profile most compatible with the experimental data. A first test of the application of the method to the BAvarian Test Machine for Negative ions beam is given.« less

The relationship between emission reductions and changes in ozone can be studied using photochemical grid models. These models are updated with new information as it becomes available. The primary objective of this study was to update the previous Collet et al. studies by using the most up-to-date (at the time the study was done) modeling emission tools, inventories, and meteorology available to conduct ozone source attribution and sensitivity studies. Results show future-year, 2030, design values for 8-hr ozone concentrations were lower than base-year values, 2011. The ozone source attribution results for selected cities showed that boundary conditions were the dominant contributors to ozone concentrations at the western U.S. locations, and were important for many of the eastern U.S. Point sources were generally more important in the eastern United States than in the western United States. The contributions of on-road mobile emissions were less than 5 ppb at a majority of the cities selected for analysis. The higher-order decoupled direct method (HDDM) results showed that in most of the locations selected for analysis, NOx emission reductions were more effective than VOC emission reductions in reducing ozone levels. The source attribution results from this study provide useful information on the important source categories and provide some initial guidance on future emission reduction strategies.

2006-01-01

Objective Critically review estimates of health insurance coverage available from different sources, including the federal government, state survey initiatives, and foundation-sponsored surveys for use in state policy research. Study Setting and Design We review the surveys in an attempt to flesh out the current weaknesses of survey data for state policy uses. The main data sources assessed in this analysis are federal government surveys (such as the Current Population Survey's Annual Social and Economic Supplement, and the National Health Interview Survey), foundation-supported surveys (National Survey of America's Families, and the Community Tracking Survey), and state-sponsored surveys. Principal Findings Despite information on estimates of health insurance coverage from six federal surveys, states find the data lacking for state policy purposes. We document the need for state representative data on the uninsured and the recent history of state data collection efforts spurred in part by the Health Resources Services Administration State Planning Grant program. We assess the state estimates of uninsurance from the Current Population Survey and make recommendations for a new consolidated federal survey with better state representative data. Conclusions We think there are several options to consider for coordinating a federal and state data collection strategy to inform state and national policy on coverage and access. PMID:16704521

Functional food awareness and perceptions in relation to information sources in older adults

PubMed Central

2014-01-01

Background The functional food industry has experienced innovative and economic expansion, yet research into consumer perceptions of functional foods and their associated health claims is limited. Among consumers, older adults could benefit from functional foods due to age-related issues pertaining to food and health. The purpose of this research was to identify the need for information related to functional foods among older adults (≥60 years old) and to assess awareness and perceptions of health claims on functional food packages. Methods Community-dwelling older adults (n = 200) completed a researcher administered questionnaire designed to collect information about functional foods including current consumption, motivating factors for consumption, perceived need for information, sources of information for functional foods and awareness of health claims. Results Prevalence of functional food consumption among participants was 93.0%. Increased awareness and knowledge was the most commonly reported factor that would promote functional food consumption (85.5%) and 63.5% of participants wanted more information about functional foods with preferred sources being newspapers/magazines/books (68.5%) and food labels (66.1%). Participants were predominately (93.5%) aware of health claims on functional foods and those with more education were more likely to report being aware of health claims (p = 0.045). Conclusions Although functional food consumption among older adults in this sample is high, there is a need for further information regarding functional foods. These results inform stakeholders regarding the potential for information to influence functional food acceptance among older adult consumers. PMID:24886306

To analyze the current proportions and characteristics of women using Internet (eHealth) and smartphone (mHealth) based sources of information during pregnancy and to investigate the influence, this information-seeking behavior has on decision-making. A cross-sectional study was conducted at two major German university hospitals. Questionnaires covering socio-demographic data, medical data and details of Internet, and smartphone application use were administered to 220 pregnant women. Data analysis utilized descriptive statistics and multiple regression analysis. 50.7 % of pregnant women were online information seekers. 22.4 % used an mHealth pregnancy application. Women using eHealth information showed no specific profile, while women using mHealth applications proved to be younger, were more likely to be in their first pregnancy, felt less healthy, and were more likely to be influenced by the retrieved information. Stepwise backward regression analysis explained 25.8 % of the variance of mHealth use. 80.5 % of cases were classified correctly by the identified predictors. All types of Web-based information correlated significantly with decision-making during pregnancy. Pregnant women frequently use the Internet and smartphone applications as a source of information. While Web usage was a common phenomenon, this study revealed specific characteristics of mHealth users during pregnancy. Improved, medically accurate smartphone applications might provide a way to specifically target the mHealth user group. As user influenceability was of major relevance to all types of information, all medical content should be carefully reviewed by a multidisciplinary board of medical specialists.

Introduction: NextGen technologies promise to provide considerable benefits in terms of enhancing operations and improving safety. However, there needs to be a thorough human factors evaluation of the way these systems will change the way in which pilot and controllers share information. The likely impact of these new technologies on pilot/controller coordinated decision making is considered in this paper using the "operational, informational and evaluative disconnect" framework. Method: Five participant focus groups were held. Participants were four experts in human factors, between x and x research students and a technical expert. The participant focus group evaluated five key NextGen technologies to identify issues that made different disconnects more or less likely. Results: Issues that were identified were: Decision Making will not necessarily improve because pilots and controllers possess the same information; Having a common information source does not mean pilots and controllers are looking at the same information; High levels of automation may lead to disconnects between the technology and pilots/controllers; Common information sources may become the definitive source for information; Overconfidence in the automation may lead to situations where appropriate breakdowns are not initiated. Discussion: The issues that were identified lead to recommendations that need to be considered in the development of NextGen technologies. The current state of development of these technologies provides a good opportunity to utilize recommendations at an early stage so that NextGen technologies do not lead to difficulties in resolving breakdowns in coordinated decision making.

Conflicting Online Health Information and Rational Decision Making: Implication for Cancer Survivors.

PubMed

Yoon, Heesoo; Sohn, Minsung; Choi, Mankyu; Jung, Minsoo

Although people in the social media age can access health information easier, they have difficulty judging conflicting rational information or summarizing the large amounts of health information available. Conflicting health information occurs when contrary assertions or information about a certain health issue comes from different information sources. This study examined the background knowledge and the current phenomenon of why conflicting health information occurs in real-world conditions. We also reviewed causes and solutions by reviewing the literature. In particular, we recommend a method that solves problems that patients have including cancer survivors who cannot themselves be active in seeking health information. Thus, we categorized the specific types of conflicting health information and analyzed the sociodemographic factors and information carrier factors that have an impact on the health information-seeking behavior of individuals.

Quantifying the Sources and Sinks of Greenhouse Gases: What Does It Take to Satisfy Scientific and Decision-Making Needs?

NASA Astrophysics Data System (ADS)

Davis, K. J.; Keller, K.; Ogle, S. M.; Smith, S.

2014-12-01

Changes in the sources and sinks of greenhouse gases (GHGs) are key drivers of anthropogenic climate change. It is hence not surprising that current and emerging U.S. governmental science priorities and programs focused on climate change (e.g. a U.S. Carbon Cycle Science Plan; the U.S. Carbon Cycle Science Program, the U.S. Global Change Research Program, Executive Order 13653 'Preparing the U.S. for the Impacts of Climate Change') all call for an improved understanding of these sources and sinks.. Measurements of the total atmospheric burden of these gases are well established, but measurements of their sources and sinks are difficult to make over spatial and temporal scales that are relevant for scientific and decisionmaking needs. Quantifying the uncertainty in these measurements is particularly challenging. This talk reviews the intersection of the state of knowledge of GHG sources and sinks, focusing in particular on CO2 and CH4, and science and decision-making needs for this information. Different science and decision-making needs require differing levels of uncertainty. A number of high-priority needs (early detection of changes in the Earth system, projections of future climate, support of markets or regulations) often require a high degree of accuracy and/or precision. We will critically evaluate current U.S. planning to documents to infer current perceived needs for GHG source/sink quantification, attempting to translate these needs into quantitative uncertainty metrics. We will compare these perceived needs with the current state of the art of GHG source/sink quantification, including the apparent pattern of systematic differences between so-called "top down" and "bottom-up" flux estimates. This comparison will enable us to identify where needs can be readily satisfied, and where gaps in technology exist. Finally, we will examine what steps could be taken to close existing gaps.

Source memory that encoding was self-referential: the influence of stimulus characteristics

PubMed Central

Durbin, Kelly A.; Mitchell, Karen J.; Johnson, Marcia K.

2017-01-01

Decades of research suggest that encoding information with respect to the self improves memory (self-reference effect, SRE) for items (item SRE). The current study focused on how processing information in reference to the self affects source memory for whether an item was self-referentially processed (a source SRE). Participants self-referentially or non-self-referentially encoded words (Experiment 1) or pictures (Experiment 2) that varied in valence (positive, negative, neutral). Relative to non-self-referential processing, self-referential processing enhanced item recognition for all stimulus types (an item SRE), but it only enhanced source memory for positive words (a source SRE). In fact, source memory for negative and neutral pictures was worse for items processed self-referentially than non-self-referentially. Together, the results suggest that item SRE and source SRE (e.g., remembering an item was encoded self-referentially) are not necessarily the same across stimulus types (e.g., words, pictures; positive, negative). While an item SRE may depend on the overall likelihood the item generates any association, the enhancing effects of self-referential processing on source memory for self-referential encoding may depend on how embedded a stimulus becomes in one’s self-schema, and that depends, in part, on the stimulus’ valence and format. Self-relevance ratings during encoding provide converging evidence for this interpretation. PMID:28276984

Exploration of Deaf People's Health Information Sources and Techniques for Information Delivery in Cape Town: A Qualitative Study for the Design and Development of a Mobile Health App.

PubMed

Chininthorn, Prangnat; Glaser, Meryl; Tucker, William David; Diehl, Jan Carel

2016-11-11

Many cultural and linguistic Deaf people in South Africa face disparity when accessing health information because of social and language barriers. The number of certified South African Sign Language interpreters (SASLIs) is also insufficient to meet the demand of the Deaf population in the country. Our research team, in collaboration with the Deaf communities in Cape Town, devised a mobile health app called SignSupport to bridge the communication gaps in health care contexts. We consequently plan to extend our work with a Health Knowledge Transfer System (HKTS) to provide Deaf people with accessible, understandable, and accurate health information. We conducted an explorative study to prepare the groundwork for the design and development of the system. To investigate the current modes of health information distributed to Deaf people in Cape Town, identify the health information sources Deaf people prefer and their reasons, and define effective techniques for delivering understandable information to generate the groundwork for the mobile health app development with and for Deaf people. A qualitative methodology using semistructured interviews with sensitizing tools was used in a community-based codesign setting. A total of 23 Deaf people and 10 health professionals participated in this study. Inductive and deductive coding was used for the analysis. Deaf people currently have access to 4 modes of health information distribution through: Deaf and other relevant organizations, hearing health professionals, personal interactions, and the mass media. Their preferred and accessible sources are those delivering information in signed language and with communication techniques that match Deaf people's communication needs. Accessible and accurate health information can be delivered to Deaf people by 3 effective techniques: using signed language including its dialects, through health drama with its combined techniques, and accompanying the information with pictures in combination with simple text descriptions. We can apply the knowledge gained from this exploration to build the groundwork of the mobile health information system. We see an opportunity to design an HKTS to assist the information delivery during the patient-health professional interactions in primary health care settings. Deaf people want to understand the information relevant to their diagnosed disease and its self-management. The 3 identified effective techniques will be applied to deliver health information through the mobile health app. ©Prangnat Chininthorn, Meryl Glaser, William David Tucker, Jan Carel Diehl.

Quantity and unit extraction for scientific and technical intelligence analysis

NASA Astrophysics Data System (ADS)

David, Peter; Hawes, Timothy

2017-05-01

Scientific and Technical (S and T) intelligence analysts consume huge amounts of data to understand how scientific progress and engineering efforts affect current and future military capabilities. One of the most important types of information S and T analysts exploit is the quantities discussed in their source material. Frequencies, ranges, size, weight, power, and numerous other properties and measurements describing the performance characteristics of systems and the engineering constraints that define them must be culled from source documents before quantified analysis can begin. Automating the process of finding and extracting the relevant quantities from a wide range of S and T documents is difficult because information about quantities and their units is often contained in unstructured text with ad hoc conventions used to convey their meaning. Currently, even simple tasks, such as searching for documents discussing RF frequencies in a band of interest, is a labor intensive and error prone process. This research addresses the challenges facing development of a document processing capability that extracts quantities and units from S and T data, and how Natural Language Processing algorithms can be used to overcome these challenges.

Investigation of Finite Sources through Time Reversal

Under certain conditions time reversal is a promising method to determine earthquake source characteristics without any a-priori information (except the earth model and the data). It consists of injecting flipped-in-time records from seismic stations within the model to create an approximate reverse movie of wave propagation from which the location of the hypocenter and other information might be inferred. In this study, the backward propagation is performed numerically using a parallel cartesian spectral element code. Initial tests using point source moment tensors serve as control for the adaptability of the used wave propagation algorithm. After that we investigated the potential of time reversal to recover finite source characteristics (e.g., size of ruptured area, rupture velocity etc.). We used synthetic data from the SPICE kinematic source inversion blind test initiated to investigate the performance of current kinematic source inversion approaches (http://www.spice-rtn.org/library/valid). The synthetic data set attempts to reproduce the 2000 Tottori earthquake with 33 records close to the fault. We discuss the influence of various assumptions made on the source (e.g., origin time, hypocenter, fault location, etc.), adjoint source weighting (e.g., correct for epicentral distance) and structure (uncertainty in the velocity model) on the results of the time reversal process. We give an overview about the quality of focussing of the different wavefield properties (i.e., displacements, strains, rotations, energies). Additionally, the potential to recover source properties of multiple point sources at the same time is discussed.

Global Partitioning of NOx Sources Using Satellite Observations: Relative Roles of Fossil Fuel Combustion, Biomass Burning and Soil Emissions

NASA Technical Reports Server (NTRS)

Jaegle, Lyatt; Steinberger, Linda; Martin, Randall V.; Chance, Kelly

2005-01-01

This document contains the following abstract for the paper "Global partitioning of NOx sources using satellite observations: Relative roles of fossil fuel combustion, biomass burning and soil emissions." Satellite observations have been used to provide important new information about emissions of nitrogen oxides. Nitrogen oxides (NOx) are significant in atmospheric chemistry, having a role in ozone air pollution, acid deposition and climate change. We know that human activities have led to a three- to six-fold increase in NOx emissions since pre-industrial times, and that there are three main surface sources of NOx: fuel combustion, large-scale fires, and microbial soil processes. How each of these sources contributes to the total NOx emissions is subject to some doubt, however. The problem is that current NOx emission inventories rely on bottom-up approaches, compiling large quantities of statistical information from diverse sources such as fuel and land use, agricultural data, and estimates of burned areas. This results in inherently large uncertainties. To overcome this, Lyatt Jaegle and colleagues from the University of Washington, USA, used new satellite observations from the Global Ozone Monitoring Experiment (GOME) instrument. As the spatial and seasonal distribution of each of the sources of NOx can be clearly mapped from space, the team could provide independent topdown constraints on the individual strengths of NOx sources, and thus help resolve discrepancies in existing inventories. Jaegle's analysis of the satellite observations, presented at the recent Faraday Discussion on "Atmospheric Chemistry", shows that fuel combustion dominates emissions at northern mid-latitudes, while fires are a significant source in the Tropics. Additionally, she discovered a larger than expected role for soil emissions, especially over agricultural regions with heavy fertilizer use. Additional information is included in the original extended abstract.

Mathematical Constraints on the Use of Transmission Line Models for Simulating Initial Breakdown Pulses in Lightning Discharges

NASA Astrophysics Data System (ADS)

da Silva, C. L.; Merrill, R. A.; Pasko, V. P.

2015-12-01

A significant portion of the in-cloud lightning development is observed as a series of initial breakdown pulses (IBPs) that are characterized by an abrupt change in the electric field at a remote sensor. Recent experimental and theoretical studies have attributed this process to the stepwise elongation of an initial lightning leader inside the thunderstorm [da Silva and Pasko, JGR, 120, 4989-5009, 2015, and references therein]. Attempts to visually observe these events are hampered due to the fact that clouds are opaque to optical radiation. Due to this reason, throughout the last decade, a number of researchers have used the so-called transmission line models (also commonly referred to as engineering models), widely employed for return stroke simulations, to simulate the waveshapes of IBPs, and also of narrow bipolar events. The transmission line (TL) model approach is to prescribe the source current dynamics in a certain manner to match the measured E-field change waveform, with the purpose of retrieving key information about the source, such as its height, peak current, size, speed of charge motion, etc. Although the TL matching method is not necessarily physics-driven, the estimated source characteristics can give insights on the dominant length- and time-scales, as well as, on the energetics of the source. This contributes to better understanding of the environment where the onset and early stages of lightning development takes place.In the present work, we use numerical modeling to constrain the number of source parameters that can be confidently inferred from the observed far-field IBP waveforms. We compare different modified TL models (i.e., with different attenuation behaviors) to show that they tend to produce similar waveforms in conditions where the channel is short. We also demonstrate that it is impossible to simultaneously retrieve the speed of source current propagation and channel length from an observed IBP waveform, in contrast to what has been previously done in the literature. Finally, we demonstrate that the simulated field-to-current conversion factor in IBP sources can vary by more than one order of magnitude, making peak current estimates for intracloud lightning processes a challenging task.

Revisions to the JDL data fusion model

NASA Astrophysics Data System (ADS)

Steinberg, Alan N.; Bowman, Christopher L.; White, Franklin E.

1999-03-01

The Data Fusion Model maintained by the Joint Directors of Laboratories (JDL) Data Fusion Group is the most widely-used method for categorizing data fusion-related functions. This paper discusses the current effort to revise the expand this model to facilitate the cost-effective development, acquisition, integration and operation of multi- sensor/multi-source systems. Data fusion involves combining information - in the broadest sense - to estimate or predict the state of some aspect of the universe. These may be represented in terms of attributive and relational states. If the job is to estimate the state of a people, it can be useful to include consideration of informational and perceptual states in addition to the physical state. Developing cost-effective multi-source information systems requires a method for specifying data fusion processing and control functions, interfaces, and associate databases. The lack of common engineering standards for data fusion systems has been a major impediment to integration and re-use of available technology: current developments do not lend themselves to objective evaluation, comparison or re-use. This paper reports on proposed revisions and expansions of the JDL Data FUsion model to remedy some of these deficiencies. This involves broadening the functional model and related taxonomy beyond the original military focus, and integrating the Data Fusion Tree Architecture model for system description, design and development.

Curation of food-relevant chemicals in ToxCast.

Karmaus, Agnes L; Trautman, Thomas D; Krishan, Mansi; Filer, Dayne L; Fix, Laurel A

2017-05-01

High-throughput in vitro assays and exposure prediction efforts are paving the way for modeling chemical risk; however, the utility of such extensive datasets can be limited or misleading when annotation fails to capture current chemical usage. To address this data gap and provide context for food-use in the United States (US), manual curation of food-relevant chemicals in ToxCast was conducted. Chemicals were categorized into three food-use categories: (1) direct food additives, (2) indirect food additives, or (3) pesticide residues. Manual curation resulted in 30% of chemicals having new annotation as well as the removal of 319 chemicals, most due to cancellation or only foreign usage. These results highlight that manual curation of chemical use information provided significant insight affecting the overall inventory and chemical categorization. In total, 1211 chemicals were confirmed as current day food-use in the US by manual curation; 1154 of these chemicals were also identified as food-related in the globally sourced chemical use information from Chemical/Product Categories database (CPCat). The refined list of food-use chemicals and the sources highlighted for compiling annotated information required to confirm food-use are valuable resources for providing needed context when evaluating large-scale inventories such as ToxCast.

Library-based illumination synthesis for critical CMOS patterning.

PubMed

Yu, Jue-Chin; Yu, Peichen; Chao, Hsueh-Yung

2013-07-01

In optical microlithography, the illumination source for critical complementary metal-oxide-semiconductor layers needs to be determined in the early stage of a technology node with very limited design information, leading to simple binary shapes. Recently, the availability of freeform sources permits us to increase pattern fidelity and relax mask complexities with minimal insertion risks to the current manufacturing flow. However, source optimization across many patterns is often treated as a design-of-experiments problem, which may not fully exploit the benefits of a freeform source. In this paper, a rigorous source-optimization algorithm is presented via linear superposition of optimal sources for pre-selected patterns. We show that analytical solutions are made possible by using Hopkins formulation and quadratic programming. The algorithm allows synthesized illumination to be linked with assorted pattern libraries, which has a direct impact on design rule studies for early planning and design automation for full wafer optimization.

Some Notes on Sparks and Ignition of Fuels

NASA Technical Reports Server (NTRS)

Fisher, Franklin A.

2000-01-01

This report compliments a concurrent analysis of the electromagnetic field threat to the fuel system of a transport aircraft. The accompanying effort assessed currents, voltages and power levels that may be induced upon fuel tank wiring from radio transmitters (inside and outside the aircraft). In addition to this, it was also essential to determine how much voltage, current, or power is required to create a fuel-vapor ignition hazard. The widely accepted minimum guideline for aircraft fuel-vapor ignition is the application of a 0.2 millijoule energy level. However, when considering radio frequency (RF) sources, this guideline is seriously inadequate. This report endeavors to bridge the gap between a traditional understanding of electrical breakdown, heating and combustion; and supplement the knowledge with available information regarding aircraft fuel-vapor ignition by RF sources

Power conversion apparatus and method

A power conversion apparatus includes an interfacing circuit that enables a current source inverter to operate from a voltage energy storage device (voltage source), such as a battery, ultracapacitor or fuel cell. The interfacing circuit, also referred to as a voltage-to-current converter, transforms the voltage source into a current source that feeds a DC current to a current source inverter. The voltage-to-current converter also provides means for controlling and maintaining a constant DC bus current that supplies the current source inverter. The voltage-to-current converter also enables the current source inverter to charge the voltage energy storage device, such as during dynamic braking of a hybrid electric vehicle, without the need of reversing the direction of the DC bus current.

Students' understanding of direct current resistive electrical circuits

NASA Astrophysics Data System (ADS)

Engelhardt, Paula Vetter; Beichner, Robert J.

2004-01-01

Both high school and university students' reasoning regarding direct current resistive electric circuits often differ from the accepted explanations. At present, there are no standard diagnostic tests on electric circuits. Two versions of a diagnostic instrument were developed, each consisting of 29 questions. The information provided by this test can provide instructors with a way of evaluating the progress and conceptual difficulties of their students. The analysis indicates that students, especially females, tend to hold multiple misconceptions, even after instruction. During interviews, the idea that the battery is a constant source of current was used most often in answering the questions. Students tended to focus on the current in solving problems and to confuse terms, often assigning the properties of current to voltage and/or resistance.

In this distributed, data-intensive era, developing any solution that requires multi-disciplinary data and service requires careful review of interfaces with data and service providers. Information is stored in many different locations and data services are distributed across the Internet. In design and development of mash-up heterogeneous data systems, the challenge is not entirely technological; it is our ability to document the external interface specifications and to create a coherent environment for our users. While is impressive to present a complex web of data, the true measure of our success is in the quality of the data we are serving, the throughput of our creation, and user experience. The presentation presents two current funded NASA projects that require integration of heterogeneous data and service that reside in different locations. The NASA Sea Level Change Portal is designed a "one-stop" source for current sea level change information. Behind this portal is an architecture that integrates data and services from various sources, which includes PI-generated products, satellite products from the DAACs, and metadata from ESDIS Common Metadata Repository (CMR) and other sources, and services reside in the data centers, universities, and ESDIS. The recently funded Distributed Oceanographic Matchup Service (DOMS) project is a project under the NASA Advance Information Technology (AIST) program. DOMS will integrate with satellite products managed by NASA Physical Oceanography Distributed Active Archive Center (PO.DAAC) and three different in-situ projects that are located in difference parts of the U.S. These projects are good examples of delivering content-rich solutions through mash-up of heterogeneous data and systems.

Many projects on developing Electronic Health Record (EHR) systems have been carried out in many countries. The current study was conducted to review the published data on the utilization of open source EHR systems in different countries all over the world. Using free text and keyword search techniques, six bibliographic databases were searched for related articles. The identified papers were screened and reviewed during a string of stages for the irrelevancy and validity. The findings showed that open source EHRs have been wildly used by source limited regions in all continents, especially in Sub-Saharan Africa and South America. It would create opportunities to improve national healthcare level especially in developing countries with minimal financial resources. Open source technology is a solution to overcome the problems of high-costs and inflexibility associated with the proprietary health information systems.

Determination of Manning's coefficient, n, for natural streams remains a challenge in practices. One source for determining the n-values that has received practitioners' attention is presenting the n-values determined from field data (measured discharge and water-surface slope) in combination of photographs and site descriptions (ancillary information). Further improvements in the visual approach can be made in presenting site characteristics and describing site ancillary information. In this manner, users can use the presented information for sites of interest with similar features. This approach in a current project on the subject for Illinois streams is discussed.

In support of the Western Arctic Shelf-Basin Interaction Project(SBI) a web-based interactive mapping server was installed on the USCGC Healy's on-board science computer network during its 2004 spring(HLY-04-02) and summer cruises (HLY-04-03) in the Chukchi and Beaufort Seas. SBI is a National Science Foundation sponsored multi-year and multidisciplinary project studying the biological productivity in the region. The mapping server was developed by the UCAR Joint Office of Science Support(JOSS) using OpenSource GIS tools(University of Minnesota Mapserver and USGS MapSurfer). Additional OpenSource tools such as GMT and MB-Systems were also utilized. The key layers in this system are the current ship track, station locations, multibeam bottom bathymetry, IBCAO bathymetry, DMSP satellite imagery , NOAA AVHRR Sea Surface temperature and all past SBI Project ship tracks and station locations. The ship track and multibeam layers are updated in real-time and the satellite layers are updated daily only during clear weather. In addition to using current high resolution multibeam bathymetry data, a composite high resolution bathymetry layer was created using multibeam data from past cruises in the SBI region. The server provides click-and-drag zooms, pan, feature query, distance measure and lat/lon/depth querys on a polar projection map of the arctic ocean. The main use of the system on the ship was for cruise track and station position planning by the scientists utilizing all available historical data and high resolution bathymetry. It was also the main source of information to all the scientist on board as to the cruise progress and plans. The system permitted on-board scientists to integrate historical cruise information for comparative purposes. A mirror web site was set up on land and the current ship track/station information was copied once a day to this site via a satellite link so people interested SBI research could follow the cruise progress.

Implementing systems of distributed receivers and transmitters for resistivity and induced polarization data is an almost inevitable result of the availability of wireless data communication modules and GPS modules offering precise timing and instrument locations. Such systems have a number of advantages; for example, they can be deployed around obstacles such as rivers, canyons, or mountains which would be difficult with traditional 'hard-wired' systems. However, deploying a system of identical, small, battery powered, transceivers, each capable of injecting a known current and measuring the induced potential has an additional and less obvious advantage in that multiple units can inject current simultaneously. The original purpose for using multiple simultaneous current sources (multi-source) was to increase signal levels. In traditional systems, to double the received signal you inject twice the current which requires you to apply twice the voltage and thus four times the power. Alternatively, one approach to increasing signal levels for large-scale surveys collected using small, battery powered transceivers is it to allow multiple units to transmit in parallel. In theory, using four 400 watt transmitters on separate, parallel dipoles yields roughly the same signal as a single 6400 watt transmitter. Furthermore, implementing the multi-source approach creates the opportunity to apply more complex current flow patterns than simple, parallel dipoles. For a perfect, noise-free system, multi-sources adds no new information to a data set that contains a comprehensive set of data collected using single sources. However, for realistic, noisy systems, it appears that multi-source data can substantially impact survey results. In preliminary model studies, the multi-source data produced such startling improvements in subsurface images that even the authors questioned their veracity. Between December of 2012 and July of 2013, we completed multi-source surveys at five sites with depths of exploration ranging from 150 to 450 m. The sites included shallow geothermal sites near Reno Nevada, Pomarance Italy, and Volterra Italy; a mineral exploration site near Timmins Quebec; and a landslide investigation near Vajont Dam in northern Italy. These sites provided a series of challenges in survey design and deployment including some extremely difficult terrain and a broad range of background resistivity and induced values. Despite these challenges, comparison of multi-source results to resistivity and induced polarization data collection with more traditional methods support the thesis that the multi-source approach is capable of providing substantial improvements in both depth of penetration and resolution over conventional approaches.

Spectroscopic measurements of current-voltage curves in scanning probe microscopy is the earliest and one of the most common methods for characterizing local energy-dependent electronic properties, providing insight into superconductive, semiconductor, and memristive behaviors. However, the quasistatic nature of these measurements renders them extremely slow. Here, we demonstrate a fundamentally new approach for dynamic spectroscopic current imaging via full information capture and Bayesian inference analysis. This "general-mode I-V"method allows three orders of magnitude faster rates than presently possible. The technique is demonstrated by acquiring I-V curves in ferroelectric nanocapacitors, yielding >100,000 I-V curves in <20 minutes. This allows detection of switching currents in the nanoscale capacitors, as well as determination of dielectric constant. These experiments show the potential for the use of full information capture and Bayesian inference towards extracting physics from rapid I-V measurements, and can be used for transport measurements in both atomic force and scanning tunneling microscopy. The data was analyzed using pycroscopy - an open-source python package available at https://github.com/pycroscopy/pycroscopy

Groundwater pollution usually is complex and concealed, remediation of which is difficult, high cost, time-consuming, and ineffective. An early warning system for groundwater pollution is needed that detects groundwater quality problems and gets the information necessary to make sound decisions before massive groundwater quality degradation occurs. Groundwater pollution early warning were performed by considering comprehensively the current groundwater quality, groundwater quality varying trend and groundwater pollution risk . The map of the basic quality of the groundwater was obtained by fuzzy comprehensive evaluation or BP neural network evaluation. Based on multi-annual groundwater monitoring datasets, Water quality state in sometime of the future was forecasted using time-sequenced analyzing methods. Water quality varying trend was analyzed by Spearman's rank correlative coefficient.The relative risk map of groundwater pollution was estimated through a procedure that identifies, cell by cell,the values of three factors, that is inherent vulnerability, load risk of pollution source and contamination hazard. DRASTIC method was used to assess inherent vulnerability of aquifer. Load risk of pollution source was analyzed based on the potential of contamination and pollution degree. Assessment index of load risk of pollution source which involves the variety of pollution source, quantity of contaminants, releasing potential of pollutants, and distance were determined. The load risks of all sources considered by GIS overlay technology. Early warning model of groundwater pollution combined with ComGIS technology organically, the regional groundwater pollution early-warning information system was developed, and applied it into Qiqiha'er groundwater early warning. It can be used to evaluate current water quality, to forecast water quality changing trend, and to analyze space-time influencing range of groundwater quality by natural process and human activities. Keywords: groundwater pollution, early warning, aquifer vulnerability, pollution load, pollution risk, ComGIS

Accounting Methodology for Source Energy of Non-Combustible Renewable Electricity Generation

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

Donohoo-Vallett, Paul

As non-combustible sources of renewable power (wind, solar, hydro, and geothermal) do not consume fuel, the “source” (or “primary”) energy from these sources cannot be accounted for in the same manner as it is for fossil fuel sources. The methodology chosen for these technologies is important as it affects the perception of the relative size of renewable source energy to fossil energy, affects estimates of source-based building energy use, and overall source energy based metrics such as energy productivity. This memo reviews the methodological choices, outlines implications of each choice, summarizes responses to a request for information on this topic,more » and presents guiding principles for the U.S. Department of Energy, (DOE) Office of Energy Efficiency and Renewable Energy (EERE) to use to determine where modifying the current renewable source energy accounting method used in EERE products and analyses would be appropriate to address the issues raised above.« less

Spatial-temporal variability in groundwater abstraction across Uganda: Implications to sustainable water resources management

The general lack of knowledge about the current rates of water abstraction/use is a challenge to sustainable water resources management in many countries, including Uganda. Estimates of water abstraction/use rates over Uganda, currently available from the FAO are not disaggregated according to source, making it difficult to understand how much is taken out of individual water stores, limiting effective management. Modelling efforts have disaggregated water use rates according to source (i.e. groundwater and surface water). However, over Sub-Saharan Africa countries, these model use estimates are highly uncertain given the scale limitations in applying water use (i.e. point versus regional), thus influencing model calibration/validation. In this study, we utilize data from the water supply atlas project over Uganda to estimate current rates of groundwater abstraction across the country based on location, well type and other relevant information. GIS techniques are employed to demarcate areas served by each water source. These areas are combined with past population distributions and average daily water needed per person to estimate water abstraction/use through time. The results indicate an increase in groundwater use, and isolate regions prone to groundwater depletion where improved management is required to sustainably management groundwater use.

Bambus 2: scaffolding metagenomes

2011-01-01

Motivation: Sequencing projects increasingly target samples from non-clonal sources. In particular, metagenomics has enabled scientists to begin to characterize the structure of microbial communities. The software tools developed for assembling and analyzing sequencing data for clonal organisms are, however, unable to adequately process data derived from non-clonal sources. Results: We present a new scaffolder, Bambus 2, to address some of the challenges encountered when analyzing metagenomes. Our approach relies on a combination of a novel method for detecting genomic repeats and algorithms that analyze assembly graphs to identify biologically meaningful genomic variants. We compare our software to current assemblers using simulated and real data. We demonstrate that the repeat detection algorithms have higher sensitivity than current approaches without sacrificing specificity. In metagenomic datasets, the scaffolder avoids false joins between distantly related organisms while obtaining long-range contiguity. Bambus 2 represents a first step toward automated metagenomic assembly. Availability: Bambus 2 is open source and available from http://amos.sf.net.
