    Reciprocity is firmly established as an important mechanism that promotes cooperation. An efficient information exchange is likewise important, especially on structured populations, where interactions between players are limited. Motivated by these two facts, we explore the role of facilitators in social dilemmas on networks. Facilitators are here mirrors to their neighbors -- they cooperate with cooperators and defect with defectors -- but they do not participate in the exchange of strategies. As such, in addition to introducing direct reciprocity, they also obstruct information exchange. In well-mixed populations, facilitators favor the replacement and invasion of defection by cooperation as long as their number exceeds a critical value. In structured populations, on the other hand, there exists a delicate balance between the benefits of reciprocity and the deterioration of information exchange. Extensive Monte Carlo simulations of social dilemmas on various interaction networks reveal that there exists an ...

    Reciprocity is firmly established as an important mechanism that promotes cooperation. An efficient information exchange is likewise important, especially on structured populations, where interactions between players are limited. Motivated by these two facts, we explore the role of facilitators in social dilemmas on networks. Facilitators are here mirrors to their neighbors—they cooperate with cooperators and defect with defectors—but they do not participate in the exchange of strategies. As such, in addition to introducing direct reciprocity, they also obstruct information exchange. In well-mixed populations, facilitators favor the replacement and invasion of defection by cooperation as long as their number exceeds a critical value. In structured populations, on the other hand, there exists a delicate balance between the benefits of reciprocity and the deterioration of information exchange. Extensive Monte Carlo simulations of social dilemmas on various interaction networks reveal that there exists an optimal interplay between reciprocity and information exchange, which sets in only when a small number of facilitators occupy the main hubs of the scale-free network. The drawbacks of missing cooperative hubs are more than compensated for by reciprocity and, at the same time, the compromised information exchange is routed via the auxiliary hubs with only marginal losses in effectivity. These results indicate that it is not always optimal for the main hubs to become leaders of the masses, but rather to exploit their highly connected state to promote tit-for-tat-like behavior.

    The exchange and use of health information can help healthcare professionals and policymakers make informed decisions on ways of improving patient and population health. Many low- and middle-income countries (LMICs) have however failed to embrace the approaches and technologies to facilitate health information exchange (HIE). We sought to understand the barriers and facilitators to the implementation and adoption of HIE in LMICs. Two reviewers independently searched 11 academic databases for published and on-going qualitative, quantitative and mixed-method studies and searched for unpublished work through the Google search engine. The searches covered the period from January 1990 to July 2014 and were not restricted by language. Eligible studies were independently, critically appraised and then thematically analysed. The searches yielded 5461 citations after de-duplication of results. Of these, 56 articles, three conference abstracts and four technical reports met the inclusion criteria. The lack of importance given to data in decision making, corruption and insecurity, lack of training and poor infrastructure were considered to be major challenges to implementing HIE, but strong leadership and clear policy direction coupled with the financial support to acquire essential technology, improve the communication network, and provide training for staff all helped to promote implementation. The body of work also highlighted how implementers of HIE needed to take into account local needs to ensure that stakeholders saw HIE as relevant and advantageous. HIE interventions implemented through leapfrog technologies such as telehealth/telemedicine and mHealth in Brazil, Kenya, and South Africa, provided successful examples of exchanging health information in LMICs despite limited resources and capability. It is important that implementation of HIE is aligned with national priorities and local needs.

    Full Text Available IntroductionThe ability to capture, exchange and use accurate information about patients and services is vital for building strong health systems, providing comprehensive and integrated patient care, managing public health risks and informing policies for public health and health financing. However, the organisational and technological systems necessary to achieve effective Health Information Exchange are lacking in many low- and middle-income countries (LMIC. Developing strategies for addressing this depends on understanding the barriers and facilitators to HIE at the individual, provider organisational, community, district, provincial and national levels. This systematic review aims to identify, critically appraise and synthesise the existing published evidence addressing these factors.ObjectiveTo assess what is known, from published / unpublished empirical studies, about barriers and facilitators to HIE in LMIC so as to identify issues that need to be addressed and approaches that can fruitfully be pursued in future improvement strategies.MethodsWe will conduct a systematic review to identify the empirical evidence base on the barriers and facilitators to HIE in LMIC.  Two reviewers will independently search 11 major international and national databases for published, unpublished and in-progress qualitative, quantitative and mixed methods studies published during 1990-July 2014 in any language. These searches of scientific databases will be supplemented by looking for eligible reports available online. The included studies will be independently critically appraised using the Mixed Method Appraisal Tool (MMAT, version 2011. Descriptive, narrative and interpretative synthesis of data will be undertaken.   Results These will be presented in a manuscript that will be published in the peer-reviewed literature. The protocol is registered with the International Prospective Register for Systematic Reviews (PROSPERO CRD 42014009826

    Full Text Available In this paper we analyze the profitability of information sharing among Cournot oligopolists receiving private information about random demand. We model the random demand as a linear demand having, 1 an unknown intercept, and 2 an unknown slope. In each of these two scenarios, firms observe private signals about the unknown parameter. We show that in the scenario-1, if the private signal observed by firms is accurate enough, information exchange is profitable and in the scenario-2, if there is a sufficiently large variation in the demand slope and private signals are accurate enough, firms earn strictly higher profits by sharing their information rather than keeping it private.Neste artigo analisamos a rentabilidade dos intercambios de informação entre oligopolistas de Cournot quando recebem informação privada sobre uma demanda que é aleatoria. Nós modelizamos a demanda aleatoria como uma demanda lineal considerando, 1 Interseção da ordenada na origem desconhecida, e 2 Inclinação desconhecida. Em cada um destes cenarios, as empresas observam sinais privados sobre o parámetro desconhecido. Nós demostramos que no primeiro cenario, se o sinal privado observado pelas empresas é suficientemente preciso, o intercambio de informação é rentavel e no último cenario, se existe uma variação suficientemente ampla na inclinação das demandas e os sinais privados observados pelas empresas são suficientemente precisos, as empresas obtem maiores lucros quando elas compartem sua informação que quando a mantem privada.

    2014-01-01

    The lead paper from Zelmer and Hagens details the substantive evolution occurring in health information technologies that has the potential to transform the relationship between consumers, health practitioners and health systems. In this commentary, the authors suggest that Canada is experiencing a shift in consumer behaviour toward a desire to actively manage one's health and wellness that is being facilitated through the advent of health applications on mobile and online technologies platforms. The result is that Canadians are now able to create personalized health solutions based on their individual health values and goals. However, before Canadians are able to derive a personal health benefit from these rapid changes in information technology, they require and are increasingly demanding greater real-time access to their own health information to better inform decision-making, as well as interoperability between their personal health tracking systems and those of their health practitioner team.

    Full Text Available The purpose of this article is to assess exchange rate forecasting possibilities with an information flow approach model. In the model the three types of information flows are distinguished: fundamental analysis information flow through particular macroeconomic determinants, microstructure approach information flow through dealer clients’ positioning data, technical analysis information flow through technical indicators. By using regression analysis it is shown that the composed model can forecast the exchange rate, the most significant information flows are distinguished. The results lead to further development of the information flow approach as a tool to forecast exchange rate fluctuations.

  13. Imperfect information facilitates the evolution of reciprocity.

    Science.gov (United States)

    2016-06-01

    The existence of cooperation demands explanation since cooperation is costly to the actor. Reciprocity has long been regarded as a potential explanatory mechanism for the existence of cooperation. Reciprocity is a mechanism wherein a cooperator responds to an opponent's behavior by switching his/her own behavior. Hence, a possible problematic case relevant to the theory of reciprocity evolution arises when the mechanism is such that the information regarding an opponent's behavior is imperfect. Although it has been confirmed also by previous theoretical studies that imperfect information interferes with the evolution of reciprocity, this argument is based on the assumption that there are no mistakes in behavior. And, a previous study presumed that it might be expected that when such mistakes occur, reciprocity can more readily evolve in the case of imperfect information than in the case of perfect information. The reason why the previous study considers so is that in the former case, reciprocators can miss defections incurred by other reciprocators' mistakes due to imperfect information, allowing cooperation to persist when such reciprocators meet. However, contrary to this expectation, the previous study has shown that even when mistakes occur, imperfect information interferes with the evolution of reciprocity. Nevertheless, the previous study assumed that payoffs are linear (i.e., that the effect of behavior is additive and there are no synergetic effects). In this study, we revisited the same problem but removed the assumption that payoffs are linear. We used evolutionarily stable strategy analysis to compare the condition for reciprocity to evolve when mistakes occur and information is imperfect with the condition for reciprocity to evolve when mistakes occur and information is perfect. Our study revealed that when payoffs are not linear, imperfect information can facilitate the evolution of reciprocity when mistakes occur; while when payoffs are linear

    2006-01-01

    Full Text Available The stock exchange represents the key institution for the development of capital market of any country. Thus the information system of every stock exchange must satisfy very strict international standards. The development of these systems is particularly difficult in countries in transition, due to intense economic and legal changes, lack of technical and financial resources, lack of experience and knowledge in the area of the capital market business, etc. Therefore the special software project management methodology for their realization must be clearly defined. In the development process of the Belgrade Stock Exchange (BSE information system a new software project management methodology for its realization has been defined, the application of which is illustrated through a series of different development stages of the Belgrade Stock Exchange information system. In order to make all the problems more comprehensive, only the continuous trading method is described, being the most frequently used trading method in the world.

  17. Managing Climate Policy Information Facilitating Knowledge Transfer to Policy Makers

    Directory of Open Access Journals (Sweden)

    Charikleia Karakosta

    2016-06-01

    Full Text Available In the challenging context of intense negotiations and radical developments in the field of climate policy, informing stakeholders about opportunities and pathways and about scientific insights and warnings is important to help create positive dynamics. Policy makers need digestible information to design good policies, and understand their options and the possible impacts of these options. They need access to well-structured knowledge, as well as appropriate techniques to manage information and data. However, available information is often difficult to access, not in the right format and of limited use to stakeholders. The range of knowledge needs identified has to be effectively addressed by providing interested parties with suitable, to-the-point information, covering the identified gaps. This is the main aim of this article that proposes the design and development of a climate policy database, which contains all the resources that can cover the identified knowledge gaps. The resources are derived from a broad range of existing reports, research and climate policy decisions at different levels. The goal is to render climate policy associated stakeholders able to extract key policy conclusions. The added value of this database was verified by users and stakeholders that generally argued that the climate policy database facilitates solid understanding of climate policy implications and fosters collaborative knowledge exchange in the field.

  3. Communicate with me: Information Exchanges between Nurses.

    Science.gov (United States)

    2015-03-01

    Patient safety and continuity of quality care are dependent on effective communication. Clinical nurse specialists at the Health Sciences Centre in Winnipeg were finding that when they sought out essential patient information from front-line nurses, they sometimes encountered gaps in knowledge about the patient. Having to acquire this information elsewhere was causing unnecessary delays in care. The authors, members of an advanced practice nurses group at the Health Sciences Centre in Winnipeg, undertook a quality improvement project to gain an understanding of the problems in information exchanges between nurses. Through interviews with front-line nurses on four units, they found that many factors contributed to the lack of knowledge nurses had about patients, such as inconsistent documentation, poorly defined plans of care and variable communication patterns. This project highlighted the need to develop a standardized handoff template to aid in information exchanges.

  4. Health information exchange: national and international approaches.

    Health information exchange (HIE), the process of electronically moving patient-level information between different organizations, is viewed as a solution to the fragmentation of data in health care. This review provides a description of the current state of HIE in seven nations, as well was three international HIE efforts, with a particular focus on the relation of exchange efforts to national health care systems, common challenges, and the implications of cross-border information sharing. National and international efforts highlighted in English language informatics journals, professional associations, and government reports are described. Fully functioning HIE is not yet a common phenomenon worldwide. However, multiple nations see the potential benefits of HIE and that has led to national and international efforts of varying scope, scale, and purview. National efforts continue to work to overcome the challenges of interoperability, record linking, insufficient infrastructures, governance, and interorganizational relationships, but have created architectural strategies, oversight agencies, and incentives to foster exchange. The three international HIE efforts reviewed represent very different approaches to the same problem of ensuring the availability of health information across borders. The potential of HIE to address many cost and quality issues will ensure HIE remains on many national agendas. In many instances, health care executives and leaders have opportunities to work within national programs to help shape local exchange governance and decide technology partners. Furthermore, HIE raises policy questions concerning the role of centralized planning, national identifiers, standards, and types of information exchanged, each of which are vital issues to individual health organizations and worthy of their attention.

    Increased information availability, timeliness, and comprehensiveness through health information exchange (HIE) can support public health practice. The potential benefits to disease monitoring, disaster response, and other public health activities served as an important justification for the US' investments in HIE. After several years of HIE implementation and funding, we sought to determine if any of the anticipated benefits of exchange participation were accruing to state and local public health practitioners participating in five different exchanges. Using qualitative interviews and template analyses, we identified public health efforts and activities that were improved by participation in HIE. HIE supported public health activities consistent with expectations in the literature. However, no single department realized all the potential benefits of HIE identified. These findings suggest ways to improve HIE usage in public health.

    Electronic health information exchange addresses a critical need in the US health care system to have information follow patients to support patient care. Today little information is shared electronically, leaving doctors without the information they need to provide the best care. With payment reforms providing a strong business driver, the demand for health information exchange is poised to grow. The Office of the National Coordinator for Health Information Technology, Department of Health and Human Services, has led the process of establishing the essential building blocks that will support health information exchange. Over the coming year, this office will develop additional policies and standards that will make information exchange easier and cheaper and facilitate its use on a broader scale.

    Science.gov (United States)

    Miller, Amalia R; Tucker, Catherine

    2014-01-01

    There are many technology platforms that bring benefits only when users share data. In healthcare, this is a key policy issue, because of the potential cost savings and quality improvements from 'big data' in the form of sharing electronic patient data across medical providers. Indeed, one criterion used for federal subsidies for healthcare information technology is whether the software has the capability to share data. We find empirically that larger hospital systems are more likely to exchange electronic patient information internally, but are less likely to exchange patient information externally with other hospitals. This pattern is driven by instances where there may be a commercial cost to sharing data with other hospitals. Our results suggest that the common strategy of using 'marquee' large users to kick-start a platform technology has an important drawback of potentially creating information silos. This suggests that federal subsidies for health data technologies based on 'meaningful use' criteria, that are based simply on the capability to share data rather than actual sharing of data, may be misplaced.

    2015-09-30

    Care transitions between settings are a well-known cause of medical errors. A key component of transition is information exchange, especially in long-term care (LTC). However, LTC is behind other settings in adoption of health information technologies (HIT). In this article, we provide some brief background information about care transitions in LTC and concerns related to technology. We describe a pilot project using HIT and secure messaging in LTC to facilitate electronic information exchange during care transitions. Five LTC facilities were included, all located within Oklahoma and serviced by the same regional health system. The study duration was 20 months. Both inpatient readmission and return emergency department (ED) visit rates were lower than baseline following implementation. We provide discussion of positive outcomes, lessons learned, and limitations. Finally, we offer implications for practice and research for implementation of HIT and information exchange across care settings that may contribute to reduction in readmission rates in acute care and ED settings.

    Full Text Available Objective. To investigate and share the major challenges and experiences of building a regional health information exchange system in China in the context of health reform. Methods. This study used interviews, focus groups, a field study, and a literature review to collect insights and analyze data. The study examined Xinjin’s approach to developing and implementing a health information exchange project, using exchange usage data for analysis. Results. Within three years and after spending approximately $2.4 million (15 million RMB, Xinjin County was able to build a complete, unified, and shared information system and many electronic health record components to integrate and manage health resources for 198 health institutions in its jurisdiction, thus becoming a model of regional health information exchange for facilitating health reform. Discussion. Costs, benefits, experiences, and lessons were discussed, and the unique characteristics of the Xinjin case and a comparison with US cases were analyzed. Conclusion. The Xinjin regional health information exchange system is different from most of the others due to its government-led, government-financed approach. Centralized and coordinated efforts played an important role in its operation. Regional health information exchange systems have been proven critical for meeting the global challenges of health reform.

    Cancer patients and their caregivers are increasingly using social media as a platform to share cancer experiences, connect with support, and exchange cancer-related information. Yet, little is known about the nature and scientific accuracy of cancer-related information exchanged on social media. We conducted a content analysis of 12 months of data from 18 publically available Facebook Pages hosted by parents of children with acute lymphoblastic leukemia (N = 15,852 posts) and extracted all exchanges of medically-oriented cancer information. We systematically coded for themes in the nature of cancer-related information exchanged on personal Facebook Pages and two oncology experts independently evaluated the scientific accuracy of each post. Of the 15,852 total posts, 171 posts contained medically-oriented cancer information. The most frequent type of cancer information exchanged was information related to treatment protocols and health services use (35%) followed by information related to side effects and late effects (26%), medication (16%), medical caregiving strategies (13%), alternative and complementary therapies (8%), and other (2%). Overall, 67% of all cancer information exchanged was deemed medically/scientifically accurate, 19% was not medically/scientifically accurate, and 14% described unproven treatment modalities. These findings highlight the potential utility of social media as a cancer-related resource, but also indicate that providers should focus on recommending reliable, evidence-based sources to patients and caregivers.

    To develop effective ways of sharing patients' medical information, we developed a new medical information exchange system (MIES) based on a registry server, which enabled us to exchange different types of data generated by various systems. To assure that patient's medical information can be effectively exchanged under different system environments, we adopted the standardized data transfer methods and terminologies suggested by the Center for Interoperable Electronic Healthcare Record (CIEHR) of Korea in order to guarantee interoperability. Regarding information security, MIES followed the security guidelines suggested by the CIEHR of Korea. This study aimed to develop essential security systems for the implementation of online services, such as encryption of communication, server security, database security, protection against hacking, contents, and network security. The registry server managed information exchange as well as the registration information of the clinical document architecture (CDA) documents, and the CDA Transfer Server was used to locate and transmit the proper CDA document from the relevant repository. The CDA viewer showed the CDA documents via connection with the information systems of related hospitals. This research chooses transfer items and defines document standards that follow CDA standards, such that exchange of CDA documents between different systems became possible through ebXML. The proposed MIES was designed as an independent central registry server model in order to guarantee the essential security of patients' medical information.

    Saccades to somatosensory targets have longer latencies and are less accurate and precise than saccades to visual targets. Here we examined how different somatosensory information influences the planning and control of saccadic eye movements. Participants fixated a central cross and initiated a saccade as fast as possible in response to a tactile stimulus that was presented to either the index or the middle fingertip of their unseen left hand. In a static condition, the hand remained at a target location for the entire block of trials and the stimulus was presented at a fixed time after an auditory tone. Therefore, the target location was derived only from proprioceptive and tactile information. In a moving condition, the hand was first actively moved to the same target location and the stimulus was then presented immediately. Thus, in the moving condition additional kinesthetic information about the target location was available. We found shorter saccade latencies in the moving compared to the static condition, but no differences in accuracy or precision of saccadic endpoints. In a second experiment, we introduced variable delays after the auditory tone (static condition) or after the end of the hand movement (moving condition) in order to reduce the predictability of the moment of the stimulation and to allow more time to process the kinesthetic information. Again, we found shorter latencies in the moving compared to the static condition but no improvement in saccade accuracy or precision. In a third experiment, we showed that the shorter saccade latencies in the moving condition cannot be explained by the temporal proximity between the relevant event (auditory tone or end of hand movement) and the moment of the stimulation. Our findings suggest that kinesthetic information facilitates planning, but not control, of saccadic eye movements to proprioceptive-tactile targets.

    To realize clinical data exchange between healthcare providers, there must be many standards in many layers. Terms and codes should be standardized, syntax to wrap the data must be mutually parsable, then transfer protocol or exchange media should be agreed. Among many standards for the syntax, HL7 and DICOM are most successful. However, everything could not be handled by HL7 solely. DICOM is good for radiology images, but, other clinical images are already handled by other "lighter" data formats like JPEG, TIFF. So, it is not realistic to use only one standard for every area of clinical information. For description of medical records, especially for narrative information, we created SGML DTD for medical information, called MML (Medical Markup Language). It is already implemented in more than 10 healthcare providers in Japan. As it is a hierarchical description of information, it is easily used as a basis of object request brokering. It is again not realistic to use MML solely for clinical information in various level of detail. Therefore, we proposed a guide-line for use of available medical standards to facilitate clinical information exchange between healthcare providers. It is called MERIT-9 (MEdical Records, Images, Texts,--Information eXchange). A typical use is HL7 files, DICOM files, referred from an MML file in a patient record, as external entities. Both MML and MERIT-9 are research projects of Japanese Ministry of Health and Welfare, and the purpose is to facilitate clinical data exchanges. They are becoming to be used in technical specifications for new hospital information systems in Japan.

    modern research overarching all of the traditional scientific disciplines. The transportation networks of planes, highways and railroads; the economic networks of global finance and stock markets; the social networks of terrorism, governments, businesses and churches; the physical networks of telephones, the Internet, earthquakes and global warming and the biological networks of gene regulation, the human body, clusters of neurons and food webs, share a number of apparently universal properties as the networks become increasingly complex. Ubiquitous aspects of such complex networks are the appearance of non-stationary and non-ergodic statistical processes and inverse power-law statistical distributions. Herein we review the traditional dynamical and phase-space methods for modeling such networks as their complexity increases and focus on the limitations of these procedures in explaining complex networks. Of course we will not be able to review the entire nascent field of network science, so we limit ourselves to a review of how certain complexity barriers have been surmounted using newly applied theoretical concepts such as aging, renewal, non-ergodic statistics and the fractional calculus. One emphasis of this review is information transport between complex networks, which requires a fundamental change in perception that we express as a transition from the familiar stochastic resonance to the new concept of complexity matching.

    2014-07-01

    Full Text Available This paper evidences the need that Tax Administrations have, within a context of economic globalization and business internationalization, to improve and intensify exchange of information in order to achieve an effective and efficient control over the application process of their domestic tax regimes. Considering the benefit maximizing strategy implemented by private economic agents in the global setting, which includes international tax planning as one of their tools, Tax administrations ought to collaborate with each other. Exchange of information is the most suitable mean to implement such collaboration. Within this context, certain taxpayers’ rights could be at stake due to the exchange process; rights that could be properly acknowledged at the domestic level, but could lack similar recognition in an international scenario.

    2017-01-01

    Full Text Available The article discusses organizational and legal aspects of electronic health information exchange in developed countries, particularly, introduction of electronic medical records in the United States and Europe, as well as topical issues related to standardization of information technologies in health care. We briefly describe the most popular standards used in e-medicine, such as Digital Imaging and Communications in Medicine (DICOM, openEHR and HL7. The questions of syntactic and semantic interoperability in the exchange of electronic medical records and some aspects of the digital signature use are also considered. We suggest mechanisms for implementation of electronic document management and sharing of digital medical information, as one of the most important directions of information technologies in health care. It is noted that today, the main limiting factor in providing the digital exchange of health information in Russian Federation is unresolved legal issues, i.e. the absence of a legal framework of electronic medical records share. At the same time, the level of IT development in our country is quite sufficient to meet current challenges. It is stated that, despite the unresolved number of problems (for example, completeness of medical data on a patient, given to relatives in critical situations, the adoption of a single electronic card is able to bring medical care to a new level, especially in emergency and urgent medicine.

In the late 1990s Fisher (writing as Pettigrew proposed information grounds to describe social settings in which people share everyday information while attending to a focal activity. Method. This study was conducted at a major research university, home to 45,000 students. Data were collected by seventy-two Master of Library and Information Science (MLIS students as part of an information behaviour class. Trained in interviewing techniques, each MLIS student interviewed ten students in public places, including the campus and the university commercial district. The survey, comprising twenty-seven primarily open-ended questions, was conducted from October 14-21, 2004. Data were collected from 729 college students and entered, along with extensive field notes, into an in-house Web form. Analysis. Qualitative and quantitative analyses were supplemented by mini-reports prepared by the student researchers along with full-team debriefings. Results. Using a 'people, place, information-related trichotomy', characteristics are discussed in terms of how they can be manipulated to optimize information flow in social settings. Conclusion. . By understanding better the characteristics of information grounds and the interactions among these characteristics, we may be able to develop social spaces in support of information flow and human interaction. Our college student and other studies suggest that information grounds play an intrinsic role in facilitating communication among people and that by building an in-depth typology, beginning with basic categorical characteristics, we may develop new methods for facilitating information exchange.

    Piette, John D; Jenchura, Emily C; Asch, Steven M; Rosland, Ann-Marie

    2013-01-01

    Background Many patients with chronic conditions are supported by out-of-home informal caregivers—family members, friends, and other individuals who provide care and support without pay—who, if armed with effective consumer health information technology, could inexpensively facilitate their care. Objective We sought to understand caregivers’ use of, interest in, and perceived barriers to health information technology for out-of-home caregiving. Methods We conducted 2 sequential Web-based surveys with a national sample of individuals who provide out-of-home caregiving to an adult family member or friend with a chronic illness. We queried respondents about their use of health information technology for out-of-home caregiving and used multivariable regression to investigate caregiver and care-recipient characteristics associated with caregivers’ technology use for caregiving. Results Among 316 out-of-home caregiver respondents, 34.5% (109/316) reported using health information technology for caregiving activities. The likelihood of a caregiver using technology increased significantly with intensity of caregiving (as measured by number of out-of-home caregiving activities). Compared with very low intensity caregivers, the adjusted odds ratio (OR) of technology use was 1.88 (95% CI 1.01-3.50) for low intensity caregivers, 2.39 (95% CI 1.11-5.15) for moderate intensity caregivers, and 3.70 (95% CI 1.62-8.45) for high intensity caregivers. Over 70% (149/207) of technology nonusers reported interest in using technology in the future to support caregiving. The most commonly cited barriers to technology use for caregiving were health system privacy rules that restrict access to care-recipients’ health information and lack of familiarity with programs or websites that facilitate out-of-home caregiving. Conclusions Health information technology use for out-of-home caregiving is common, especially among individuals who provide more intense caregiving. Health care

    Full Text Available This study aims to develop a social media GIS (Geographic Information Systems specially tailored to information exchange between regions. The conclusions of this study are summarized in the following three points.(1 Social media GIS is a geographic information system which integratesWeb-GIS, SNS and Twitter into a single system. A social media GIS was conducted for the collection of regional information in the eastern part of Yamanashi Prefecture. The social media GIS uses a design which displays its usefulness in multi-directional information transmission and in easing the limitations of space, time and continuity, making it possible to redesign systems in accordance with target cases.(2 During the operation of the social media GIS for about two months, most of the users were in their20s. Users exchanged regional information using the comment and button functions.(3The system was evaluated based on the results of a questionnaire to users and an access analysis oflog data during operationin order to identify measures for improvement of the system. Because of users’ high evaluations of its original functions, the overall operability of the system was highly evaluated. Most of the contributed information was only known to local residents, and it was evident that the system fulfilled its intended role.

    2009-07-01

    Full Text Available Finite-time approach allows one to optimize regimes of processes in macrosystems when duration of the processes is restricted. Driving force of the processes is difference of intensive variables: temperatures in thermodynamics, values in economics, etc. In microeconomic systems two counterflow fluxes appear due to the only driving force. They are goods and money fluxes. Another possible case is two fluxes with the same direction. The processes of information exchange can be described by this formalism.

  15. Closed Loop Brain Model of Neocortical Information Based Exchange

    Directory of Open Access Journals (Sweden)

    James eKozloski

    2016-01-01

    Full Text Available Here we describe an information based exchange' model of brain function that ascribes to neocortex, basal ganglia, and thalamus distinct network functions. The model allows us to analyze whole brain system set point measures, such as the rate and heterogeneity of transitions in striatum and neocortex, in the context of neuromodulation and other perturbations. Our closed-loop model is grounded in neuroanatomical observations, proposing a novel Grand Loop through neocortex, and invokes different forms of plasticity at specific tissue interfaces and their principle cell synapses to achieve these transitions. By implementing a system for maximum information based exchange of action potentials between modeled neocortical areas, we observe changes to these measures in simulation. We hypothesize that similar dynamic set points and modulations exist in the brain's resting state activity, and that different modifications to information based exchange may shift the risk profile of different component tissues, resulting in different neurodegenerative diseases. This model is targeted for further development using IBM's Neural Tissue Simulator, which allows scalable elaboration of networks, tissues, and their neural and synaptic components towards ever greater complexity and biological realism.

    2015-01-01

    Investment of resources to purposively improve the movement of information between health system providers is currently made with imperfect information. No inventories of system-level digital information flows currently exist, nor do measures of inter-organizational electronic information. exchange (HIE). Using Protégé 4, an open-source OWL Web ontology language editor and knowledge-based framework we formalized a model that decomposes inter-organizational electronic health information flow into derivative concepts such as diversity, breadth, volume, structure, standardization and connectivity. Self-reported data from a regional health system is used to measure HIE; the ontology identifies providers with low and high HIE, useful for planners, and using a related database is used to monitor data quality.

An individual security model is a fully customised specification of access control information for information exchange within a particular business environment. We introduce transaction based business process models (BPM) and utilise these models for a formal transformation to {open_quotes}need-to-know{close_quotes} authorisations. Therefore, we allocate information from BPMs which can be transformed to access control information and derive a specification of an organisation`s individual security model. Our approach provides transparency of security design because the design method ensures that a security model is directly related to the business. Moreover, security effort and costs will be reduced because BPMs must not be specified for security reasons and security design can be automated. BPMs are a result of management activities and therefore, existing resources from a security point of view.

    Latino farmworkers in North Carolina are a hard-to-reach population that faces diverse occupational health risks, including pesticide exposure. Health and safety education efforts often employ lay health advisor or promotor(a) de salud models in which farmworker community members are trained to provide health education. As a frequently tight-knit and isolated group, farmworkers may be well suited to serve as resident lay health advisors. This paper presents data collected from a nonrandom sample of Latino farmworkers living in North Carolina regarding the natural level of occupational safety information exchange among Latino farmworkers, specifically pesticide safety information. The data affirm that farmworkers informally exchange occupational safety information with one another, with the level of exchange increasing during the agricultural season. Consequently, if trained, the data suggest that farmworkers might be situated to provide in situ occupational health and safety education to their peers. This remains to be systematically tested and evaluated.

    Establishing fundamentals for regulating cell behavior with engineered physical environments, such as topography and stiffness, requires a large number of cell culture experiments. However, cell culture experiments in cell-surface interaction studies are generally labor-intensive and time-consuming due to many experimental tasks, such as multiple fabrication processes in sample preparation and repetitive medium exchange in cell culture. In this work, a novel aquatic flower-inspired cell culture platform (AFIP) is presented. AFIP aims to facilitate the experiments on the cell-surface interaction studies, especially the medium exchange process. AFIP was devised to capture and dispense cell culture medium based on interactions between an elastic polymer substrate and a liquid medium. Thus, the medium exchange can be performed easily and without the need of other instruments, such as a vacuum suction and pipette. An appropriate design window of AFIP, based on scaling analysis, was identified to provide a criterion for achieving stability in medium exchange as well as various surface characteristics of the petal substrates. The developed AFIP, with physically engineered petal substrates, was also verified to exchange medium reliably and repeatedly. A closed structure capturing the medium was sustained stably during cell culture experiments. NIH3T3 proliferation results also demonstrated that AFIP can be applied to the cell-surface interaction studies as an alternative to the conventional method.

    People with congenital prosopagnosia have never developed the ability to accurately recognize faces. This single case investigation systematically investigates covert and overt face recognition in "C.," a 69 year-old woman with congenital prosopagnosia. Specifically, we: (a) describe the first assessment of covert face recognition in congenital prosopagnosia using multiple tasks; (b) show that semantic information can contribute to covert recognition; and (c) provide a theoretical explanation for the mechanisms underlying covert face recognition.

  2. What should we measure? Conceptualizing usage in health information exchange.

    2010-01-01

    Under the provisions of the Health Information Technology for Economic & Clinical Health act providers need to demonstrate their 'meaningful use' of electronic health record systems' health information exchange (HIE) capability. HIE usage is not a simple construct, but the choice of its measurement must attend to the users, context, and objectives of the system being examined. This review examined how usage is reported in the existing literature and also what conceptualizations of usage might best reflect the nature and objectives of HIE. While existing literature on HIE usage included a diverse set of measures, most were theoretically weak, did not attend to the interplay of measure, level of analysis and architectural strategy, and did not reflect how HIE usage affected the actual process of care. Attention to these issues will provide greater insight into the effects of previously inaccessible information on medical decision-making and the process of care.

    Patients with damage to the primary visual cortex (V1) demonstrate residual visual performance during laboratory tasks despite denying having a conscious percept. The mechanisms behind such performance, often called blindsight, are not fully understood, but the use of surgically-induced unilateral V1 lesions in macaque monkeys provides a useful animal model for exploring such mechanisms. For example, V1-lesioned monkeys localize stimuli in a forced-choice condition while at the same time failing to report awareness of identical stimuli in a yes-no detection condition, similar to human patients. Moreover, residual cognitive processes, including saliency-guided eye movements, bottom-up attention with peripheral non-informative cues, and spatial short-term memory, have all been demonstrated in these animals. Here we examined whether post-lesion residual visuomotor processing can be modulated by top-down task knowledge. We tested two V1-lesioned monkeys with a visually guided saccade task in which we provided an informative foveal pre-cue about upcoming target location. Our monkeys fixated while we presented a leftward or rightward arrow (serving as a pre-cue) superimposed on the fixation point (FP). After various cue-target onset asynchronies (CTOAs), a saccadic target (of variable contrast across trials) was presented either in the affected (contra-lesional) or seeing (ipsi-lesional) hemifield. Critically, target location was in the same hemifield that the arrow pre-cue pointed towards in 80% of the trials (valid-cue trials), making the cue highly useful for task performance. In both monkeys, correct saccade reaction times were shorter during valid than invalid trials. Moreover, in one monkey, the ratio of correct saccades towards the affected hemifield was higher during valid than invalid trials. We replicated both reaction time and correct ratio effects in the same monkey using a symbolic color cue. These results suggest that V1-lesion monkeys can use informative

    As health care providers adopt and make “meaningful use” of health information technology (health IT), communities and delivery systems must set up the infrastructure to facilitate health information exchange (HIE) between providers and numerous other stakeholders who have a role in supporting health and care. By facilitating better communication and coordination between providers, HIE has the potential to improve clinical decision-making and continuity of care, while reducing unnecessary use of services. When implemented as part of a broader strategy for health care delivery system and payment reform, HIE capability also can enable the use of analytic tools needed for population health management, patient engagement in care, and continuous learning and improvement. The diverse experiences of seven communities that participated in the three-year federal Beacon Community Program offer practical insight into factors influencing the technical architecture of exchange infrastructure and its role in supporting improved care, reduced cost, and a healthier population. The case studies also document challenges faced by the communities, such as significant time and resources required to harmonize variations in the interpretation of data standards. Findings indicate that their progress developing community-based HIE strategies, while driven by local needs and objectives, is also influenced by broader legal, policy, and market conditions.

    2014-04-01

    There is a growing recognition of the critical role information management can play in shaping effective humanitarian response, coordination and decision-making. Quality information, reaching more humanitarian actors, will result in better coordination and better decision-making, thus improving the response to beneficiaries as well as accountability to donors. The humanitarian response to the 2010 Haiti earthquake marked a watershed moment for humanitarian information management. Yet the fragmented nature of the response and the use of hierarchical models of information management, along with other factors, have led some observers to label the Haiti response a failure. Using an analytical framework often found in humanitarian emergencies, this study analyses challenges to information flow in the Haiti case and the implications for effective humanitarian response. It concludes by offering possible paths for overcoming such challenges, and for restoring the value and utility of humanitarian information management and exchange in humanitarian relief settings. © 2014 The Author(s).

  8. Does participation in health information exchange improve hospital efficiency?

    Walker, Daniel M

    2017-02-24

    The federal government allocated nearly $30 billion to spur the development of information technology infrastructure capable of supporting the exchange of interoperable clinical data, leading to growth in hospital participation in health information exchange (HIE) networks. HIEs have the potential to improve care coordination across healthcare providers, leading ultimately to increased productivity of health services for hospitals. However, the impact of HIE participation on hospital efficiency remains unclear. This dynamic prompts the question asked by this study: does HIE participation improve hospital efficiency. This study estimates the effect of HIE participation on efficiency using a national sample of 1017 hospitals from 2009 to 2012. Using a two-stage analytic design, efficiency indices were determined using the Malmquist algorithm and then regressed on a set of hospital characteristics. Results suggest that any participation in HIE can improve both technical efficiency change and total factor productivity (TFP). A second model examining total years of HIE participation shows a benefit of one and three years of participation on TFP. These results suggest that hospital investment in HIE participation may be a useful strategy to improve hospital operational performance, and that policy should continue to support increased participation and use of HIE. More research is needed to identify the exact mechanisms through which HIE participation can improve hospital efficiency.

    Full Text Available Introduction. The function load in modern systems distributes often between several operators. Prognostication of information exchange efficiency between operators is actual problem. Problem statement. The problem solving is possible with distinguishing the individual operator and all other operators. In such situation it is possible to carry out the prognosis procedure on macroscopic level. Theoretical results. Parities between indicators of efficiency and relative errors of operators are established. Laws of operator relative error changes are defined. Dependence of the operator error relations in the beginning and in the end of prognostication is analyzed. Time of task performance in view with the provided requirements to a relative error of one or other operators is defined. It is shown that prognostication procedure provides definition of a necessary parity of operator relative errors in the beginning of their work for maintenance of their certain parity through set time at the set parameters which consider constants of increase efficiency of work. Conclusion. The results give the chance to pass from the static description and an estimation of work efficiency of operator’s group to the dynamic description and formation of look-ahead model which considers processes of a mutual information exchange between operators.

    Today, the exchange of information in the Internet is dominated by the WWW and e-mail. Discussion groups like mailing lists and newsgroups also permit communication in groups. Information retrieval becomes a crucial challenge in using the Internet. In the field of medicine, three more aspects are of special importance: privacy, legal requirements, and the necessity of transferring large amounts of data. For these problems, today's Internet doesn't provide a sufficient solution yet. Future developments will not only improve the existing services, but also lead to fundamental changes in the transfer technologies: Safer data transfer is to be ensured by new encrypting software together with the planned transfer protocol IPv6. Introducing the new transfer mode ATM will lead to better and resource saving transmission. Computer, telephone and TV networks will grow together, resulting in convergence of media.

    Mobile agents have been implemented in e-Commerce to search and filter information of interest from electronic markets. When the information is very sensitive and critical, it is important to develop a novel security protocol that can efficiently protect the information from malicious tampering as well as unauthorized disclosure or at least detect any malicious act of intruders. In this chapter, we describe robust security techniques that ensure a sound security of information gathered throughout agent’s itinerary against various security attacks, as well as truncation attacks. A sound security protocol is described, which implements the various security techniques that would jointly prevent or at least detect any malicious act of intruders. We reason about the soundness of the protocol usingSymbolic Trace Analyzer (STA), a formal verification tool that is based on symbolic techniques. We analyze the protocol in key configurations and show that it is free of flaws. We also show that the protocol fulfils the various security requirements of exchanged information in MAS, including data-integrity, data-confidentiality, data-authenticity, origin confidentiality and data non-repudiability.

    Unlike consumer goods industries, healthcare has been slow to implement technolo gies that support exchange of data in patients' health records. This results in avoid able medication errors, avoidable hospital readmissions, unnecessary duplicate testing, and other inefficient or wasteful practices. Community-based regional health information exchange (HIE) organizations have evolved in response to federal aims to encourage interoperability, yet little is known about their strategic approach. We use the lens of institutional and strategic management theories to empirically explore the differences in business strategies deployed in HIEs that are, to date, financially sustainable versus those that are not. We developed a 20-question survey targeted to CEOs to assess HIE business strategies. Our sample consisted of 60 community-based exchanges distributed throughout the United States, and we achieved a 58% response rate. Questions centered on competitive strategy and financial sustainability. We relied on logistic regression methods to explore relationships between variables. Our regression identified characteristics common to sustainable organizations. We defined sustainability as revenues exceeding operational costs. Seventeen of the 35 organizations (49%) defined themselves as currently sustainable. Focus and cost leadership strategies were significantly associated with sustainability. Growth strate gies, which were much more common than other strategies, were not associated with sustainability. We saw little evidence of a differentiation strategy (i.e., the basis of competition whereby the attributes of a product or service are unmatched by rivals). Most CEOs had a relatively optimistic outlook, with 60% stating they were confident of surviving over the next 5 years; however, nearly 9% of the organizations were in some phase of divestiture or exit from the market. HIEs are evolving differently based on local leadership decisions, yet their strategic approach is

    To estimate costs and benefits for Australia of implementing health information exchange interoperability among health care providers and other health care stakeholders. A cost-benefit model considering four levels of interoperability (Level 1, paper based; Level 2, machine transportable; Level 3, machine readable; and Level 4, machine interpretable) was developed for Government-funded health services, then validated by expert review. Roll-out costs for Level 3 and Level 4 interoperability were projected to be $21.5 billion and $14.2 billion, respectively, and steady-state costs, $1470 million and $933 million per annum, respectively. Level 3 interoperability would achieve steady-state savings of $1820 million, and Level 4 interoperability, $2990 million, comprising transactions of: laboratory $1180 million (39%); other providers, $893 million (30%); imaging centre, $680 million (23%); pharmacy, $213 million (7%) and public health, $27 million (1%). Net steady-state Level 4 benefits are projected to be $2050 million: $1710 million more than Level 3 benefits of $348 million, reflecting reduced interface costs for Level 4 interoperability due to standardisation of the semantic content of Level 4 messages. Benefits to both providers and society will accrue from the implementation of interoperability. Standards are needed for the semantic content of clinical messages, in addition to message exchange standards, for the full benefits of interoperability to be realised. An Australian Government policy position supporting such standards is recommended.

  1. Self-Service Banking: Value Creation Models and Information Exchange

    Directory of Open Access Journals (Sweden)

    Ragnvald Sannes

    2001-01-01

    Full Text Available This paper argues that most banks have failed to exploit the potential of self-service banking because they base their service design on an incomplete business model for self-service. A framework for evaluation of self-service banking concepts is developed on the basis of Stabell and Fjeldstad's three value configurations. The value network and the value shop are consistent with self-service banking while the value chain is inappropriate. The impact of the value configurations on information exchange and self-service functionality is discussed, and a framework for design of such services proposed. Current self-service banking practices are compared to the framework, and it is concluded that current practice matches the concept of a value network and not the value shop. However, current practices are only a partial implementation of a value network-based self-service banking concept.

    Joseph, Bwalya Kelvin

    In most parts of the world, political systems which utilize authoritative rule and mostly employ top-down decision-making processes are slowly transcending towards democratic norms. Information Technology Systems have been identified and adopted as one of the most efficient vehicles for appropriate, transparent and inclusive / participatory decision making. Zambia has shown a higher propensity to indigenous knowledge systems which are full of inefficiencies, a lot of red tape in public service delivery, and prone to corrupt practices. Despite that being the case, it is slowly trying to implement e-government. The adoption of e-government promises a sharp paradigm shift where public institutions will be more responsive and transparent, promote efficient PPP (Public Private Partnerships), and empower citizens by making knowledge and other resources more directly accessible. This paper examines three cases from Zambia where ICT in support of e-government has been implemented for Development Information Exchange (DIE) - knowledge-based decision making. The paper also assesses the challenges, opportunities, and issues together with e-government adoption criteria regarding successful encapsulation of e-government into the Zambian contextual environment. I propose a conceptual model which offers balanced e-government adoption criteria involving a combination of electronic and participatory services. This conceptual e-government adoption model can later be replicated to be used at the Southern African Development Community (SADC) level given the similarity in the contextual environment.

    The major objectives of the SIEGate project were to improve the security posture and minimize the cyber-attack surface of electric utility control centers and to reduce the cost of maintaining control-room-to-control-room information exchange. Major project goals included the design, development, testing, and commercialization of a single security-hardened appliance that could meet industry needs for resisting cyber-attacks while protecting the confidentiality and integrity of a growing volume of real-time information needed to ensure the reliability of the bulk electric system and interoperating with existing data formats and networking technologies. The SIEGate project has achieved its goals and objectives. The SIEGate Design Document, issued in March 2012, presented SIEGate use cases, provided SIEGate requirements, established SIEGate design principles, and prescribed design functionality of SIEGate as well as the components that make up SIEGate. SIEGate Release Version 1.0 was posted in January 2014. Release Version 1.0.83, which was posted on March 28, 2014, fixed many issues discovered by early adopters and added several new features. Release Candidate 1.1, which added additional improvements and bug fixes, was posted in June 2014. SIEGate executables have been downloaded more than 300 times. SIEGate has been tested at PJM, Entergy, TVA, and Southern. Security testing and analysis of SIEGate has been conducted at PNNL and PJM. Alstom has provided a summary of recommended steps for commercialization of the SIEGate Appliance and identified two deployment models with immediate commercial application.

    Nanoscale zerovalent iron (nZVI) usually suffers from reduction of reactivity by aggregation, difficulty of assembling, environmental release and health concerns. Furthermore, data are lacking on the effect of cheap nickel on debromination of decabromodiphenyl ether (DBDE) by immobilized nZVI in aqueous system. In this study, strong acid polystyrene cation-exchange resins with particle diameter from 0.4 to 0.6 mm were utilized as matrices to immobilize bimetallic nickel-iron nanoparticles in order to minimize aggregation and environmental leakage risks of nZVI and to enhance their reactivity. Elemental distribution mapping showed that iron particles distributed uniformly on the surface of the resin and nickel particles were dispersed homogeneously into Fe phase. The reaction rate of resin-bound nZVI is about 55% higher than that of dispersed nZVI. The immobilized bimetallic nanoparticles with 9.69% Ni had the highest debromination percent (96%) and reaction rate (0.493 1/h). The existence of Ni significantly improved the debromination rate, due to the surface coverage of catalytic metal on the reductive metal and the formation of a galvanic cell. The environmental dominant congeners, such as BDE 154, 153, 100, 99 and 47, were produced during the process. Outstanding reactive performance, along with magnetic separation assured that resin-bound bimetallic nickel-iron nanoparticles are promising material that can be utilized to remediate a wide variety of pollutants contaminated sites including polybrominated diphenyl ethers.

    There is growing recognition of the importance of sharing health information in home care; however, limited research exists to identify appropriate strategies, especially with home care providers. We engaged home care stakeholders from three locations in Ontario to determine facilitators, barriers, and recommendations for using health information in home care. The results suggest that health professionals recognize the potential of these systems to enhance communication through several emergent themes; however, there was a lack of agreement on the current facilitators, barriers, and recommendations for future interventions. More research is needed to achieve consensus before strategies for improvement can be initiated.

    With decreasing budgets and increasing pressure on completing cleanup missions as quickly, safely and cost-effectively as possible, there is significant benefit to be gained from collaboration and joint efforts between organizations facing similar issues. With this in mind, the US Department of Energy (DOE) and the UK Nuclear Decommissioning Authority (NDA) have formally agreed to share information on lessons learned on the development and application of new technologies and approaches to improve the safety, cost effectiveness and schedule of the cleanup legacy wastes. To facilitate information exchange a range of tools and methodologies were established. These included tacit knowledge exchange through facilitated meetings, conference calls and Site visits as well as explicit knowledge exchange through document sharing and newsletters. A DOE web-based portal has been established to capture these exchanges and add to them via discussion boards. The information exchange is operating at the Government-to-Government strategic level as well as at the Site Contractor level to address both technical and managerial topic areas. This effort has resulted in opening a dialogue and building working relationships. In some areas joint programs of work have been initiated thus saving resource and enabling the parties to leverage off one another activities. The potential benefits of high quality information exchange are significant, ranging from cost avoidance through identification of an approach to a problem that has been proven elsewhere to cost sharing and joint development of a new technology to address a common problem. The benefits in outcomes significantly outweigh the costs of the process. The applicability of the tools and methods along with the lessons learned regarding some key issues is of use to any organization that wants to improve value for money. In the waste management marketplace, there are a multitude of challenges being addressed by multiple organizations and

  12. Towards systematic information exchange and reuse in e-laboratories

    In many disciplines of sciences, technology advances in data acquisition and processing are progressively reducing the cost of producing scientific information. At the same time, the consequent proliferation of available information on a large scale poses a number of problems regarding its preservation, controlled dissemination, and reuse. While all of these areas involve interesting data management challenges, we believe that the latter two also present an opportunity for new and interesting experiments on the nature of social interactions within scientific communities. As part of its ongoing contributions in the area of cyberinfrastructure for science, the myGrid consortium (University of Manchester and University of Southampton, UK) has recently created a social networking environment, called myExperiment, where such experiments can be conducted. For the past year, myExperiment has successfully challenged the notion that scientists are reluctant to share their knowledge with their peers: the site has so far collected over a thousand artifacts, both data and processes (specifications of scientific workflows used in actual practice) from over 100 contributors, with about 2,500 registered users. We are now testing the idea that information-centric scientific interaction can be modelled around the notion of "research objects". These are compound units of information that are self-consistent, in that they aggregate data that is logically related, and that can be exchanged among peers using well-defined formats and protocols. An example is a compound that contains (i) the formal and executable specification of an experiment, encoded as a workflow; (semantic) annotations that formally describe attribution and derivation properties of the experiment; (ii) test cases with sample inputs and expected outputs; (iii) a provenance trace with the details on some past execution that led to interesting results; and possibly more related components, depending on the intended type

    Spacecraft formation flying involves the coordination of states among multiple spacecraft through relative sensing, inter-spacecraft communication, and control. Most existing formation-flying estimation algorithms can only be supported via highly centralized, all-to-all, static relative sensing. New algorithms are proposed that are scalable, modular, and robust to variations in the topology and link characteristics of the formation exchange network. These distributed algorithms rely on a local information exchange network, relaxing the assumptions on existing algorithms. Distributed space systems rely on a signal transmission network among multiple spacecraft for their operation. Control and coordination among multiple spacecraft in a formation is facilitated via a network of relative sensing and interspacecraft communications. Guidance, navigation, and control rely on the sensing network. This network becomes more complex the more spacecraft are added, or as mission requirements become more complex. The observability of a formation state was observed by a set of local observations from a particular node in the formation. Formation observability can be parameterized in terms of the matrices appearing in the formation dynamics and observation matrices. An agreement protocol was used as a mechanism for observing formation states from local measurements. An agreement protocol is essentially an unforced dynamic system whose trajectory is governed by the interconnection geometry and initial condition of each node, with a goal of reaching a common value of interest. The observability of the interconnected system depends on the geometry of the network, as well as the position of the observer relative to the topology. For the first time, critical GN&C (guidance, navigation, and control estimation) subsystems are synthesized by bringing the contribution of the spacecraft information-exchange network to the forefront of algorithmic analysis and design. The result is a

    Rowland, Christopher A; DeLosh, Edward L

    2014-12-01

    Testing is a powerful means to boost the retention of information. The extent to which the benefits of testing generalize to nontested information, however, is not clear. In three experiments, we found that completing cued-recall tests for a subset of studied materials enhanced retention for the specific information tested, as well as for associated, nontested information during later free-recall testing. In Experiment 1, this generalized benefit was revealed for lists of category-exemplar pairs. Experiment 2 extended the effect to unrelated words, suggesting that retrieval can enhance later free recall of nontested information that is bound solely through episodic context. In Experiment 3, we manipulated the format of the final test and found facilitation in free-recall, but not in cued-recall, testing. The results suggest that testing may facilitate later free recall in part by enhancing access to information that is present during a prior temporal or list context. More generally, these findings suggest that retrieval-induced facilitation extends to a broader range of conditions than has previously been suggested, and they further motivate the adoption of testing as a practical and effective learning tool.

    Millions of consumers seek health information on the Internet. Unfortunately, this searching often falls short because of design limitations of many consumer-oriented Web sites. In this paper, we describe an approach that addresses several known barriers to consumer health information seeking. This approach primarily involves maintaining the referential context throughout a consumer's search for information. To maintain referential context, this approach uses multiple levels of hierarchical constructs to organize complex information, and data elements are toggled to minimize the need for scrolling. An information resource based on this approach was implemented for information about smoking using standard Web technologies. The resource was evaluated by 31 diverse consumers through standardized usability instruments. Consumers found the resource to be easy to navigate and to use. We conclude that the approach described in this manuscript could be applied more broadly to facilitate the organization and presentation of consumer health information.

    The growing importance of animal diseases and zoonoses at a time when globalisation has increased movements of people, animals and animal products across the globe, has strengthened the role of the World Organisation for Animal Health (OIE) in animal disease control. The OIE's mandate since its establishment in 1924 has been to facilitate the exchange of public health, animal health and scientific information, and to further the control and eradication of animal diseases. The OIE is recognised by the World Trade Organization Agreement on the Application of Sanitary and Phytosanitary Measures as the international reference organisation for animal diseases and zoonoses, especially for standard setting. The standards adopted by the World Assembly of OIE Delegates on veterinary public health and animal health feature in the OlE Terrestrial Animal Health Code, the Aquatic Animal Health Code, the Manual of Diagnostic Tests and Vaccines for Terrestrial Animals and the Manual of Diagnostic Tests for Aquatic Animals. The OlE is also a reference organisation for the exchange of public and animal health information among Member Countries, through an information, reporting and warning system based on transparent communication between countries. The OIE provides scientific expertise in ascertaining countries' status with regard to notifiable diseases, enabling them to secure official recognition as being free from foot and mouth disease, African horse sickness, contagious bovine pleuropneumonia and bovine spongiform encephalopathy. The OIE also contributes its scientific expertise to stakeholder training on the surveillance and control of animal diseases and zoonoses and to the evaluation of the performance of Veterinary Services, to enhance theirwork asthe cornerstone of their countries' disease control efforts.

    Full Text Available Introduction: To ensure continuity of care, it is important to effectively communicate the health status of older patients who are transferred between health care organizations. The objectives of this study were to: (1 evaluate the prevalence of nursing transfer documents, and (2 identify patient and transfer characteristics associated with the presence of nursing transfer documents for older patients transferred from home care to hospital and back to home care again after hospitalization.Methods: Nursing documents were reviewed from a total of 102 records of older inpatients admitted from home care to medical wards at a local hospital in central Norway and later discharged home. Frequencies were used to describe patient and transfer characteristics, and the prevalence of transfer documents. Pearson's chi-square test and logistic regression were used to identify possible associations between patient and transfer characteristics and the presence of nursing transfer documents.Results: While nursing admission notes were present in 1% of the patient transfers from home care to the hospital, 69% of patient discharges from the hospital to home care were accompanied by nursing discharge notes. Patient and transfer characteristics associated with the presence of a nursing discharge note were age, gender, medical department facility, and length of hospital stay.Conclusions: The low prevalence of nursing transfer documents constitutes a challenge to the continuity of care for hospitalized home care patients. Patient and transfer characteristics may impact the nurses' propensity to exchange patient information. These findings emphasize the need for nurses and managers to improve the exchange of written information. While nurses must strive to transfer accurate patient information at the right place and at the right time, the managers must facilitate this by providing appropriate guidelines and standards, as well as adequate personnel and resources.

    Small group learning is an interactive activity that requires a skilled teacher with the ability to facilitate and debrief. Approximately 250 students from seven health professions were enrolled in a first year interprofessional education course that focused on the importance of communication and collaboration. Weekly faculty debrief sessions were conducted and were utilized to share the teachers perspectives with facilitative teaching as well as for feedback and improvement strategies. Recommendations included linking the learning within the small group sessions back to clinical and professional practice in order to validate the course content and thereby increase student engagement; creation of facilitator guides with specific debrief instructions for the given objectives in order to encourage effective learning dialogue among all participants; and providing faculty with formalized facilitator training as well as debrief strategies in order to attain the skills to better guide student learning.

    In this paper, we present the DeepTree exhibit, a multi-user, multi-touch interactive visualization of the Tree of Life. We developed DeepTree to facilitate collaborative learning of evolutionary concepts. We will describe an iterative process in which a team of computer scientists, learning scientists, biologists, and museum curators worked together throughout design, development, and evaluation. We present the importance of designing the interactions and the visualization hand-in-hand in order to facilitate active learning. The outcome of this process is a fractal-based tree layout that reduces visual complexity while being able to capture all life on earth; a custom rendering and navigation engine that prioritizes visual appeal and smooth fly-through; and a multi-user interface that encourages collaborative exploration while offering guided discovery. We present an evaluation showing that the large dataset encouraged free exploration, triggers emotional responses, and facilitates visitor engagement and informal learning.

    The new requirement for "collaboration" between multidisciplinary collaborators induces to exchange and share adequate information on the product, processes throughout the products' lifecycle. Thus, effective capture of information, and also its extraction, recording, exchange, sharing, and reuse become increasingly critical. These lead companies to adopt new improved methodologies in managing the exchange and sharing of information. The aim of this paper is to describe a collaborative framework system to exchange and share information, which is based on: (i) The Product Process Collaboration Organization model (PPCO) which defines product and process information, and the various collaboration methods for the organizations involved in the supply chain. (ii) Viewpoint model describes relationships between each actor and the comprehensive Product/Process model, defining each actor's "domain of interest" within the evolving product definition.

    Medical information exchange and integration is the effective method to solve the interoperability and medical information island, and is the basis of medical information sharing. In this paper, we take medical texts and medical images as the basic integrated objects, DICOM, HL7 messages and datasets as the integrated units, efficient DI-COM, HL7 message construction and parsing methods as basis, design and realize a universal medical information integration and exchange service middleware. Experimental results show that the prototype system could perform medical information integration and exchange among relational database, HL7 and DICOM message, provide a feasible scheme to solve the medical information island and lay a good foundation for establishing the unified medical information integration and sharing platform. The middleware has been applied in the project named "development and demonstration of opened medical information integration system".

    Grossman, Joy M; Kushner, Kathryn L; November, Elizabeth A

    2008-02-01

    Local health information exchanges (HIEs) hold the promise of collecting patient clinical data across sites of care to provide more complete and timely information for treatment, as well as supporting quality improvement and reporting, public health activities, and clinical research. Findings from a study of stakeholder perspectives on participation in four HIEs by the Center for Studying Health System Change (HSC) and the National Institute for Health Care Management (NIHCM) Foundation suggest, however, that barriers to achieving data exchange remain high. Concerns about loss of competitive advantage and data misuse impede provider and health plan willingness to contribute patient data. Additionally, uncertainty about who benefits from HIEs is affecting stakeholder willingness to fund the exchanges. The more mature exchanges--Cincinnati-based HealthBridge and the Indiana Health Information Exchange (IHIE)--have achieved some viability by meeting a specific business need--more efficient delivery of hospital test results to physicians. The newer exchanges--CareSpark, serving northeast Tennessee and southwest Virginia, and the Tampa Bay Regional Health Information Organization (RHIO)--have struggled to identify and finance initial services without a similar critical mass of hospital participation. While narrow data exchange efforts that improve transaction efficiency may be a pragmatic first step to overcome barriers to stakeholder participation, expanding HIEs to achieve the broad-based data exchange necessary for quality reporting and pay-for-performance (P4P) activities raises more challenges.

    The EU FP7 TRIDEC project focuses on enabling real-time, intelligent, information management of collaborative, complex, critical decision processes for earth management. A key challenge is to promote a communication infrastructure to facilitate interoperable environment information services during environment events and crises such as tsunamis and drilling, during which increasing volumes and dimensionality of disparate information sources, including sensor-based and human-based ones, can result, and need to be managed. Such a system needs to support: scalable, distributed messaging; asynchronous messaging; open messaging to handling changing clients such as new and retired automated system and human information sources becoming online or offline; flexible data filtering, and heterogeneous access networks (e.g., GSM, WLAN and LAN). In addition, the system needs to be resilient to handle the ICT system failures, e.g. failure, degradation and overloads, during environment events. There are several system middleware choices for TRIDEC based upon a Service-oriented-architecture (SOA), Event-driven-Architecture (EDA), Cloud Computing, and Enterprise Service Bus (ESB). In an SOA, everything is a service (e.g. data access, processing and exchange); clients can request on demand or subscribe to services registered by providers; more often interaction is synchronous. In an EDA system, events that represent significant changes in state can be processed simply, or as streams or more complexly. Cloud computing is a virtualization, interoperable and elastic resource allocation model. An ESB, a fundamental component for enterprise messaging, supports synchronous and asynchronous message exchange models and has inbuilt resilience against ICT failure. Our middleware proposal is an ESB based hybrid architecture model: an SOA extension supports more synchronous workflows; EDA assists the ESB to handle more complex event processing; Cloud computing can be used to increase and

    Full Text Available In this paper, we have examined the short-run movement of the won/dollar exchange rate using information obtained from the inter-bank market in Korea. First, we constructed the hourly measure of excess demand for dollar and used it as a proxy for the trading pattern of market participants. To construct this time series, we relied on the bid and ask won/dollar exchange rates collected on the two-minute interval. We then estimated the structural VAR model consisting of the actually observed won/dollar exchange rate and the proxied trading pattern of market participants to see if private information, as opposed to public information, is relevant for explaining the hourly movement of the won/dollar exchange rate. Private information is found to account for more 30% of hourly variations of the won/dollar exchange rate. Next, we constructed the trading pattern of market participants on a daily basis using the same data set employed to build the hourly measure. We then examined whether private information is useful for predicting the daily won/dollar exchange rate movement. We found that the forecast model using both private and public information reduces out-of-sample forecast errors of an alternative model relying only on public information by 20~25%. Also, the out-of-sample forecast of the model using both private and public information is found to be more accurate than the random walk model.

    Full Text Available In financial markets, transparency of financial information is one of the most effective variables of investment strategies. Information asymmetry can seriously affect firm performance on the stock exchange and firms with a poor informational environment can lose the interest of investors. Reducing information asymmetry can have an important effect on firm performance on the stock exchange. Firms may lack a clear informational environment in the market because of the emerging conditions governing the Tehran Stock Exchange. Because larger and more active firms on the Tehran Stock Exchange provide more information, measuring the informational environment of these firms provides an overview of information asymmetry. The present study calculated the information asymmetry in these firms using the PIN and FE indices. The inconsistent results provided by these indices prompted the authors to offer a new index that is a composite of the PIN and FE that can better explain information asymmetry in developing market such as Asian stock markets. The results show that the new composite index, by using the mechanisms of the PIN and FE indices, provides a better outcome. The new composite index shows that the Tosee Melli Inv (TMEL1, Mobarakeh Steel (FOLD1, Iran Mobil Tele (HMRZ1, Saipa (SIPA1 and I.N.C. Ind. (MSMI1 firms have a better informational environment on the Tehran Stock Exchange.

  4. You Should Know Better: Can Self-Affirmation Facilitate Information-Seeking Behavior and Interpersonal Discussion?

    This study explores whether self-affirmation has the capacity not merely to reduce the perceived threat associated with health-related information but also to facilitate interpersonal discussion and affect health information-seeking behavior. The context for the study is the ongoing California drought, which serves as suitable context to examine the intersection of self-affirmation and information-seeking behavior because it involves a threatening message (the destructive consequences of the drought) and highlights discrepancies between actual (water waste) and prosocial (water conservation) behavior. Results of a month-long longitudinal panel study demonstrate significant effects of self-affirmation on interpersonal discussion, information seeking, knowledge, and water-conserving behavior across time. Implications for theorizing longer term effects of self-affirmation and practical implications for promoting behavioral change through the enhancement of knowledge and self-esteem are considered.

  5. Facilitating the improved management of waste in South Africa through a national waste information system.

    Developing a waste information system (WIS) for a country is more than just about collecting routine data on waste; it is about facilitating the improved management of waste by providing timely, reliable information to the relevant role-players. It is a means of supporting the waste governance challenges facing South Africa - challenges ranging from strategic waste management issues at national government to basic operational challenges at local government. The paper addresses two hypotheses. The first is that the identified needs of government can provide a platform from which to design a national WIS framework for a developing country such as South Africa, and the second is that the needs for waste information reflect greater, currently unfulfilled challenges in the sustainable management of waste. Through a participatory needs analysis process, it is shown that waste information is needed by the three spheres of government, to support amongst others, informed planning and decision-making, compliance monitoring and enforcement, community participation through public access to information, human, infrastructure and financial resource management and policy development. These needs for waste information correspond closely with key waste management challenges currently facing the country. A shift in governments approach to waste, in line with national and international policy, is evident from identified current and future waste information needs. However, the need for information on landfilling remains entrenched within government, possibly due to the poor compliance of landfill sites in South Africa and the problems around the illegal disposal of both general and hazardous waste.

    Retrieving specific information from large amounts of documentation is not an easy task. It could be facilitated if information relevant in the current problem solving context could be automatically supplied to the user. As a first step towards this goal, we have developed an intelligent hypertext system called CID (Computer Integrated Documentation) and tested it on the Space Station Freedom requirement documents. The CID system enables integration of various technical documents in a hypertext framework and includes an intelligent context-sensitive indexing and retrieval mechanism. This mechanism utilizes on-line user information requirements and relevance feedback either to reinforce current indexing in case of success or to generate new knowledge in case of failure. This allows the CID system to provide helpful responses, based on previous usage of the documentation, and to improve its performance over time.

  9. Improving GHG inventories by regional information exchange: a report from Asia

    2006-08-01

    Full Text Available Abstract Background The Parties to the United Nations Framework Convention on Climate Change (UNFCCC are required to develop and report a national inventory of greenhouse gases not controlled by the Montreal Protocol. In the Asia region, "Workshops on Greenhouse Gas Inventories in Asia (WGIA" have been organised annually since 2003 under the support of the government of Japan. WGIAs promote information exchange in the region to support countries' efforts to improve the quality of greenhouse gas inventories. This paper reports the major outcomes of the WGIAs and discusses the key aspects of information exchange in the region for the improvement of inventories. Results The major outcomes of WGIAs intended to help countries improve GHG inventories, can be summarised as follows: (1 identification of common issues and possible solutions by sector, (2 reporting country inventory practices, and (3 verification of the UNFCCC reporting requirements. Conclusion The workshops provided the opportunity for countries to share common issues and constraints pertinent to GHG inventories and to exchange information regarding possible solutions for those issues based on their own experience. The relevance of information exchange is determined due to emission sources, emitting mechanisms from sources, and technologies used. Information exchange about emission sources that are unique to Asia, like those of the agriculture sector, contributes significantly to the accumulation of knowledge at the regional and global levels. Enabling countries to verify their national circumstances with the reporting requirements under UNFCCC is also an essential part of the WGIA information exchange activities.

    Unprecedented efforts are underway across the United States to electronically capture and exchange health information to improve health care and population health, and reduce costs. This increased collection and sharing of electronic patient data raises several governance issues, including privacy, security, liability, and market competition. Those engaged in such efforts have had to develop data sharing agreements (DSAs) among entities involved in information exchange, many of whom are "nontraditional" health care entities and/or new partners. This paper shares lessons learned based on the experiences of six federally funded communities participating in the Beacon Community Cooperative Agreement Program, and offers guidance for navigating data governance issues and developing DSAs to facilitate community-wide health information exchange. While all entities involved in electronic data sharing must address governance issues and create DSAs accordingly, until recently little formal guidance existed for doing so - particularly for community-based initiatives. Despite this lack of guidance, together the Beacon Communities' experiences highlight promising strategies for navigating complex governance issues, which may be useful to other entities or communities initiating information exchange efforts to support delivery system transformation. For the past three years, AcademyHealth has provided technical assistance to most of the 17 Beacon Communities, 6 of whom contributed to this collaborative writing effort. Though these communities varied widely in terms of their demographics, resources, and Beacon-driven priorities, common themes emerged as they described their approaches to data governance and DSA development. The 6 Beacon Communities confirmed that DSAs are necessary to satisfy legal and market-based concerns, and they identified several specific issues, many of which have been noted by others involved in network data sharing initiatives. More importantly, these

    The development and introduction of platforms that enable interdisciplinary exchange on current developments and projects in the area of eHealth have been stimulated by different authorities. The aim of this project was to develop a repository of eHealth projects that will make the wealth of eHealth projects visible and enable mutual learning through the sharing of experiences and good practice. The content of the database and search criteria as well as their categories were determined in close co-ordination and cooperation with stakeholders from the specialist areas. Technically, we used Java Server Faces (JSF) for the implementation of the frontend of the web application. Access to structured information on projects can support stakeholders to combining skills and knowledge residing in different places to create new solutions and approaches within a network of evolving competencies and opportunities. A regional database is the beginning of a structured collection and presentation of projects, which can then be incorporated into a broader context. The next step will be to unify this information transparently.

    2012-01-01

    Market mechanisms are entering into new fields of economy, in which some constraints of physical world, e.g. Kirchoffs Law in power grid, must be taken into account during trading. On such markets, some of commodities, like telecommunication bandwidth or electrical energy, appear to be non-storable, and must be exchanged in real-time. On the other hand, the markets tend to react at shortest possible time, so an idea to delegate some competency to autonomous software agents is very attractive. Multi-commodity mechanism addresses the aforementioned requirements. Modeling the relationships between the commodities allows to formulate new, more sophisticated models and mechanisms, which reflect decision situations in a better manner. Application of multi-commodity approach requires solving several issues related to data modeling, communication, semantics aspects of communication, reliability, etc. This book answers some of the questions and points out promising paths for implementation and development.

    2011-09-01

    The article gives an account of a study on the impact of facilitating information literacy education (FILE) on its participants, health librarians who have attended this course between 2007 and 2010. The analysis presented here is based on the first stage of the research, funded by the Higher Education Academy Information and Computer Sciences and consisting of an online survey. This survey was conducted in Autumn 2010 and examined the respondents' examples of information literacy practice before and after FILE. Two main outcomes can be drawn from the data. First, that overall the respondents' provision of information literacy education has shifted from a tutor-centred approach (where the trainer decides what the learner needs) to a learner-centred approach (where the learner decides what he/she needs). And secondly, that the impact of FILE should be seen in terms of a self-perpetuating professional development, rather than measured in terms of specific changes that occur at set times (e.g., at the end of the course or 6 months after completion). As one FILE participant puts it: 'When FILE ends your career as an information literacy professional starts.' © 2011 The authors.

    The success of space missions depends to a large extent on their information support. The infrastructure and the routine work on receiving telemetry information, passing it to the computing centers, preprocessing, and delivery to the users (participants of scientific experiments) must be maintained around the clock all over the spacecraft flight period that usually lasts several years. All these functions must be performed promptly because the operating modes of the on board scientific equipment are scheduled on the basis of data received from the spacecraft. Nowadays, the information support of space missions is unthinkable without developing and managing a special information resource (WEB site) in the Internet. The WEB site of the mission is a means of coordination of the efforts of all participants of a scientific experiment and, simultaneously, a valuable tool for making the results obtained available to the scientific community.

    Repetitive questions and requests for information are common in older adults with dementia. The purpose of this environmental design intervention was to provide residents continuous access to information about common mealtime questions with the intent of decreasing agitation around mealtimes and facilitating more pleasant patient-staff and patient-patient interactions. A special care unit for residents with dementia of the Alzheimer's type was the setting. During the intervention conditions, a large clock and a sign with large lettering that identified mealtimes were hung in the dining area. Direct observations of 35 residents were conducted at mealtimes for a 5-month period. Results showed reductions from baseline to the intervention phase in food-related questions or requests. These results suggest a simple, inexpensive environmental change intervention can reduce repetitive questions commonly exhibited by individuals with dementia.

    2009-12-01

    Full Text Available Being charged with the task of accessioning and supplying of living microbiological material, microbial culture collections are institutions that play a central role between the interests of a variety of user communities. On the one side are the providers of living microbiological material, such as individual scientists, institutions and countries of origin and on the other side are the various kinds of recipients/users of cultures of microorganisms from academia and industry. Thus, providing access to high quality biological material and scientific services while at the same time observing donor countries' rights, intellectual property rights, biosafety and biosecurity aspects poses demanding challenges. E.g. donor countries rights relate to Article 15 of the Convention on Biological Diversity: "Contracting parties …. recognize the sovereign rights of states over their natural resources …. shall facilitate access to resources … and not impose restrictions that run counter to the aims of the Convention. Access to natural resources shall be by mutually agreed terms and subject to prior informed consent ..." The use of a proposed standard contract by culture collections is discussed as a way of contractually safeguarding the existing research commons, while observing the new rights established in the Convention on Biological Diversity as well as other existing and new legislation impacting on the accessibility of living microbial material.

    Full Text Available Abstract Background Information exchange networks for chronic illness care may influence the uptake of innovations in patient care. Valid and feasible methods are needed to document and analyse information exchange networks in healthcare settings. This observational study aimed to examine the usefulness of methods to study information exchange networks in primary care practices, related to chronic heart failure, diabetes and chronic obstructive pulmonary disease. Methods The study was linked to a quality improvement project in the Netherlands. All health professionals in the practices were asked to complete a short questionnaire that documented their information exchange relations. Feasibility was determined in terms of response rates and reliability in terms of reciprocity of reports of receiving and providing information. For each practice, a number of network characteristics were derived for each of the chronic conditions. Results Ten of the 21 practices in the quality improvement project agreed to participate in this network study. The response rates were high in all but one of the participating practices. For the analysis, we used data from 67 health professionals from eight practices. The agreement between receiving and providing information was, on average, 65.6%. The values for density, centralization, hierarchy, and overlap of the information exchange networks showed substantial variation between the practices as well as between the chronic conditions. The most central individual in the information exchange network could be a nurse or a physician. Conclusions Further research is needed to refine the measure of information networks and to test the impact of network characteristics on the uptake of innovations.

    Shea, Peter J.; Blake, Eric

    2011-06-01

    Modern tracking and fusion settings involve multiple platforms in different locations, tracking different target tracks, focusing on different regions of interest, while using different update rates and sensor resolutions with the goal of providing increased situation awareness in the region by fusing together the diversity of information from each platform. In this paper, a decentralized, distributed fusion architecture is presented along with results and trade studies comparing performance to that of a centralized fusion architecture. The decentralized distributed architecture is designed to work with legacy tracking systems and uses an efficient message passing scheme to share information and coordinate tracks across a diverse group of platforms. This system does not rely on a central node and allows for track information to be maintained at the local level while utilizing track information from other platforms to increase situation awareness. We compare the performance between our distributed approach and a centralized system using simulated airborne sensors operating in overlapping regions of interest with target densities and routes chosen to demonstrate tradeoffs between the different architectures. Preliminary results show that the decentralized distributed system provides similar performance to the centralized fusion system in terms of situation awareness relative to traditional tracking metrics, but at the cost of using an increased communication bandwidth to provide frequent updates to neighboring platforms. Results demonstrate the tradeoff between flexibility and optimality - configuration of the distributed decentralized system to provide increased flexibility and robustness comes at the cost of reduced situation awareness as compared to the centralized system.

    The theory is presented for resonance interaction between two atoms in an excited configuration: one atom, the "receptor" of information (i.e. energy), adsorbed on a phospholipid surface and the other atom, the "emitter" of information (i.e. energy), a long distance away. The dielectric function for a specific phospholipid membrane is obtained from density functional theory calculations. We present numerical results comparing the range and magnitude of non-specific Casimir-Polder interactions with the much more long-ranged, and highly specific, resonance interaction. A study of the resonance interaction with one or both atoms adsorbed on a phospholipid membrane surface reveals a possibility to have a cross over from attraction to repulsion or from repulsion to attraction at separations between receptor and emitter atoms exceeding several hundred {\\AA}ngstr\\"oms. The energy transfer and the observed transitions in the sign of the interaction energies near surfaces provide potential new ways to start recognitio...

    In this paper we explore the onset of cooperative traits in the public goods game. This well-known game involves N-agent interactions and thus reproduces a large number of social scenarios in which cooperation appears to be essential. Many studies have recently addressed how the structure of the interaction patterns influences the emergence of cooperation. Here we study how information about the payoffs collected by each individual in the different groups it participates in influences the decisions made by its group partners. Our results point out that cross-information plays a fundamental and positive role in the evolution of cooperation for different versions of the public goods game and different interaction structures.

  14. Automatic exchange of information: towards a new global standard of tax transparency

    Miguel Eduardo Pecho Trigueros

    2014-07-01

    Full Text Available Tax authorities are increasingly relying on mutual cooperation with their foreign peers to enforce more effectively their internal tax laws. After the banking scandals of 2008 and the subsequent global financial crisis, the Global Forum on Transparency and Exchange of Information for TaxPurposes has proposed the exchange of information upon request as the fiscal transparency standard. However, some measures adopted by the European Union, previous initiatives from the Organization for Economic Cooperation and Development (OECD and, above all, the introduction of the Foreign Account Tax Compliance Act (Fatca by the United States in 2010 have promoted the need to adopt the automatic exchange of information as the new fiscal transparency standard. Automatic exchange of information allows home countries to verify whether their taxpayers have correctly included foreign income, allowing tax authorities to have early warning of possible noncompliance cases. In February 2014, the OECD published its proposal for a new global model of automatic exchange of financial account information. The new global model contains the necessary legal instruments and due diligence and reporting procedures, mainly for financial institutions.

    Person-centered care is heavily dependent on effective information exchange among health care team members. We explored the organizational systems that influence resident care attendants' (RCAs) access to care information in long-term care (LTC) settings. We conducted an institutional ethnography in three LTC facilities. Investigative methods included naturalistic observations, in-depth interviews, and textual analysis. Practical access to texts containing individualized care-related information (e.g., care plans) was dependent on job classification. Regulated health care professionals accessed these texts daily. RCAs lacked practical access to these texts and primarily received and shared information orally. Microsystems of care, based on information exchange formats, emerged. Organizational systems mandated written exchange of information and did not formally support an oral exchange. Thus, oral information exchanges were largely dependent on the quality of workplace relationships. Formal systems are needed to support structured oral information exchange within and between the microsystems of care found in LTC.

    This research looks at the characteristics of social networks of rural people in different careers and income conditions.The study also investigates information exchange amongst rural people.The aim of this research is to analyze social networks’implication in the information exchange of rural people in China.Design/methodology/approach:The field work investigation of this study is a questionnaire survey of the egocentric social networks of 660 rural people in China.The characteristics of social networks are revealed through social network analysis(SNA).Findings:Analysis of quantitative date indicates that the social networks of Chinese rural people are small sized,filled with very strong ties and characterized by high-homogeneity.These characteristics limit the exchange of useful and new information.Research limitations:This survey was taken on a small scale of respondents.It did not focus on the information poverty issue,though the results indicate that a strong information divide exists amongst rural people.Practical implications:The social networks of rural people are viewed as their main information exchange channel on the one hand;however on the other hand,they does play a negative role in ameliorating information poverty.Through these social networks,rural people with different educational backgrounds and income levels suffer the information divide.Originality/value:This research focuses on the seven kinds of information which are crucial in rural people’s living and productivity.The connection between the characteristics of social networks and information exchange are revealed.

  19. Status of international cooperation and east-west information exchange

    Science.gov (United States)

    Lawrence, Barbara; Bernacki, Adam

    It is proposed that there are certain necessary conditions for sci-tech intellectual transfer to appear in significant, and therefore noticeable, proportions. The two obvious conditions are the existence of a "donor" country (a country which experiences a surplus of intellectual output) and a "recipient" country (one which manages to accommodate foreign intellectual production in its publications). The sci-tech intellectual transfer is likely to occur when the publishing potential of a given country exceeds its intellectual production or when the quality and importance of research performed abroad surpasses internal accomplishments. Patterns of Soviet aerospace science as information donor and recipient have been investigated in a case study. An assessment of two decades of AIAA's (the American Institute of Aeronautics and Astronautics) coverage of the Soviet aerospace and engineering literature in the Aerospace Database demonstrates that the former Soviet Union has been transformed from a recipient of foreign intellectual effort to a donor country. Aspects of utilization/integration of Soviet information are examined, and a survey of the AIAA Journal suggests that Soviet literature entering the U.S. via the alternative channel of distribution (i.e., as a result of international intellectual transfer) is far more likely to be integrated into the mainstream of actively utilized aerospace knowledge. Suggestions for change in this area are presented, with emphasis on ways to reduce language barriers.

  20. Taxonomic information exchange and copyright: the Plazi approach

    2009-03-01

    Full Text Available Abstract Background A large part of our knowledge on the world's species is recorded in the corpus of biodiversity literature with well over hundred million pages, and is represented in natural history collections estimated at 2 – 3 billion specimens. But this body of knowledge is almost entirely in paper-print form and is not directly accessible through the Internet. For the digitization of this literature, new territories have to be chartered in the fields of technical, legal and social issues that presently impede its advance. The taxonomic literature seems especially destined for such a transformation. Discussion Plazi was founded as an association with the primary goal of transforming both the printed and, more recently, "born-digital" taxonomic literature into semantically enabled, enhanced documents. This includes the creation of a test body of literature, an XML schema modeling its logic content (TaxonX, the development of a mark-up editor (GoldenGATE allowing also the enhancement of documents with links to external resources via Life Science Identifiers (LSID, a repository for publications and issuance of bibliographic identifiers, a dedicated server to serve the marked up content (the Plazi Search and Retrieval Server, SRS and semantic tools to mine information. Plazi's workflow is designed to respect copyright protection and achieves extraction by observing exceptions and limitations existent in international copyright law. Conclusion The information found in Plazi's databases – taxonomic treatments as well as the metadata of the publications – are in the public domain and can therefore be used for further scientific research without any restriction, whether or not contained in copyrighted publications.

    This project has covered a series of exercises and exercise like activities, in addition to a survey of scenario development tools and development of a suggestion for a Nordic system for data and information exchange. The results from the activities are presented in this report in a methodical perspective. The results reveal three similar components in almost all exercise activities: tools and methods to be used in an emergency situation need further development, systems for communication and information exchange should be developed and implemented, and the format and content of the information to be exchanged in an emergency situation should be agreed upon. Recommendations for future tasks regarding Nordic exercises are given according to this methodical approach. A major aspect here is to develop strategies for the over-all emergency planning. Such strategies should include the use of systematically chosen exercise types to improve the emergency response in a systematic way. (au)

    The mechanisms by which histones are disassembled and reassembled into nucleosomes and chromatin structure during DNA replication, repair and transcription are poorly understood. A better understanding of the processes involved is, however, crucial if we are to understand whether and how histone variants and post-translationally modified histones are inherited in an epigenetic manner. To this end we have studied the interaction of the histone H3-H4 complex with the human retinoblastoma-associated protein RbAp48 and their exchange with a second histone chaperone, anti-silencing function protein 1 (ASF1). Exchange of histones H3-H4 between these two histone chaperones has a central role in the assembly of new nucleosomes, and we show here that the H3-H4 complex has an unexpected structural plasticity, which is important for this exchange.

    Several researchers share the concern of healthcare information systems failing to support communication and collaboration in clinical practices. The objective of this paper is to investigate the current state of computer-supported patient information exchange and associated communication between clinicians. We report findings from a national survey on Finnish physicians? experiences with their currently used clinical information systems with regard to patient information documentation, retrieval, management and exchange-related tasks. The questionnaire study with 3929 physicians indicated the main concern being cross-organisational patient information delivery. In addition, physicians argued computer usage increasingly steals time and attention from caring activities and even disturbs physician?nurse collaboration. Problems in information management were particularly emphasised among those physicians working in hospitals and wards. The survey findings indicated that collaborative applications and mobile or wireless solutions have not been widely adapted in Finnish healthcare and suggested an urgent need for adopting appropriate information and communication technology applications to support information exchange and communication between physicians, and physicians and nurses.

  8. Inositol phospholipids regulate the guanine-nucleotide-exchange factor Tiam1 by facilitating its binding to the plasma membrane and regulating GDP/GTP exchange on Rac1.

    Binding of the Rac1-specific guanine-nucleotide-exchange factor, Tiam1, to the plasma membrane requires the N-terminal pleckstrin homology domain. In the present study, we show that membrane-association is mediated by binding of PtdIns(4,5)P(2) to the pleckstrin homology domain. Moreover, in 1321N1 astrocytoma cells, translocation of Tiam1 to the cytosol, following receptor-mediated stimulation of PtdIns(4,5)P(2) breakdown, correlates with decreased Rac1-GTP levels, indicating that membrane-association is required for GDP/GTP exchange on Rac1. In addition, we show that platelet-derived growth factor activates Rac1 in vivo by increasing PtdIns(3,4,5)P(3) concentrations, rather than the closely related lipid, PtdIns(3,4)P(2). Finally, the data demonstrate that PtdIns(4,5)P(2) and PtdIns(3,4,5)P(3) bind to the same pleckstrin homology domain in Tiam1 and that soluble inositol phosphates appear to compete with lipids for this binding. Together, these novel observations provide strong evidence that distinct phosphoinositides regulate different functions of this enzyme, indicating that local concentrations of signalling lipids and the levels of cytosolic inositol phosphates will play crucial roles in determining its activity in vivo.

    Introduction: Social networks (1) have been embedded in our daily life for a long time. They constitute a powerful tool used nowadays for both searching and exchanging information on different issues by using Internet searching engines (Google, Bing, etc.) and Social Networks (Facebook, Twitter etc.). In this paper, are presented the results of a research based on the frequency and the type of the usage of the Internet and the Social Networks by the general public and the health professionals. Objectives: The objectives of the research were focused on the investigation of the frequency of seeking and meticulously searching for health information in the social media by both individuals and health practitioners. The exchanging of information is a procedure that involves the issues of reliability and quality of information. Methods: In this research, by using advanced statistical techniques an effort is made to investigate the participant’s profile in using social networks for searching and exchanging information on health issues. Results: Based on the answers 93 % of the people, use the Internet to find information on health-subjects. Considering principal component analysis, the most important health subjects were nutrition (0.719 %), respiratory issues (0.79 %), cardiological issues (0.777%), psychological issues (0.667%) and total (73.8%). Conclusions: The research results, based on different statistical techniques revealed that the 61.2% of the males and 56.4% of the females intended to use the social networks for searching medical information. Based on the principal components analysis, the most important sources that the participants mentioned, were the use of the Internet and social networks for exchanging information on health issues. These sources proved to be of paramount importance to the participants of the study. The same holds for nursing, medical and administrative staff in hospitals. PMID:27482135

    2014-09-01

    The aim of this study was to explore Jordanian women's experiences of information exchange following diagnosis of early stage breast cancer. A purposive sample of 28 women who had surgery for early stage breast cancer within 6 months prior to the interview and had treatment at three hospitals in Central and Northern Jordan was recruited for the study. Data were collected using semi-structured individual interviews focused on women's communication experiences at diagnosis and during cancer treatment. Interviews were audio taped, transcribed verbatim in Arabic, and analyzed using conventional content analysis. Three main themes associated with information exchange were revealed as follows: (1) knowledge about breast cancer and its treatment, (2) communication of cancer diagnosis and treatment, and (3) educating on treatment side effects. Misconceptions about breast cancer risk factors, consequences of breast cancer treatment, and breast cancer-related symptoms were common among participants. Women made important health-related decisions based on misconceptions. Physician's information giving, availability, and responses to women's questions varied by their level of education and the type and location of treatment facility. Informational exchange experiences vary among Jordanian women diagnosed with breast cancer and raise concern over opportunities offered these women to engage in informed decision making. Findings suggest a need for nurses to assess the information needs of Jordanian women newly diagnosed with breast cancer and provide education tailored to individual needs. There is also a need to develop Arabic educational materials and make these available for patients at treatment facilities in all regions of Jordan.

  20. A Systematic Process to Facilitate Evidence-Informed Decisionmaking Regarding Program Expansion.

    2014-01-01

    While the Department of Defense supports more than 200 psychological health and traumatic brain injury programs, it lacks an approach and process to systematically develop, track, and assess the performance of this portfolio of programs. Further, there is not yet a uniform approach to decisionmaking around program support and expansion of particularly promising, evidence-based programs. This lack of centralized oversight may result in the proliferation of untested programs that are developed without an evidence base; an inefficient use of resources; and added cost and administrative inefficiencies. RAND researchers developed a potential model and tools to support a centralized, systematic, and ongoing process to help in making decisions around continued program support, and by which expansion can be facilitated. This study includes two tools. The first is a Program Abstraction Form, which collects relevant background information from programs and asks explicitly about program effectiveness and the design of the program evaluation used to assess program effectiveness, as a poor evaluation design may lead to incorrect conclusions about the effectiveness of the program. The second is the RAND Program Expansion Tool, which provides a standardized summary of the quality and outcome of a program evaluation. The focus of these tools is on decisionmaking around program expansion, and does not preclude or address initial funding decisions of particularly promising new programs that may not yet have a solid evidence base.

  1. Tracking down the path of memory: eye scanpaths facilitate retrieval of visuospatial information.

    Bochynska, Agata; Laeng, Bruno

    2015-09-01

    Recent research points to a crucial role of eye fixations on the same spatial locations where an item appeared when learned, for the successful retrieval of stored information (e.g., Laeng et al. in Cognition 131:263-283, 2014. doi: 10.1016/j.cognition.2014.01.003 ). However, evidence about whether the specific temporal sequence (i.e., scanpath) of these eye fixations is also relevant for the accuracy of memory remains unclear. In the current study, eye fixations were recorded while looking at a checkerboard-like pattern. In a recognition session (48 h later), animations were shown where each square that formed the pattern was presented one by one, either according to the same, idiosyncratic, temporal sequence in which they were originally viewed by each participant or in a shuffled sequence although the squares were, in both conditions, always in their correct positions. Afterward, participants judged whether they had seen the same pattern before or not. Showing the elements serially according to the original scanpath's sequence yielded a significantly better recognition performance than the shuffled condition. In a forced fixation condition, where the gaze was maintained on the center of the screen, the advantage of memory accuracy for same versus shuffled scanpaths disappeared. Concluding, gaze scanpaths (i.e., the order of fixations and not simply their positions) are functional to visual memory and physical reenacting of the original, embodied, perception can facilitate retrieval.

    2012-07-01

    The intramolecular distances of anion and cation exchanger sites of zwitterionic chiral stationary phases represent potential tuning sites for enantiomer selectivity. In this contribution, we investigate the influence of alkanesulfonic acid chain length and flexibility on enantiomer separations of chiral acids, bases, and amphoteric molecules for six Cinchona alkaloid-based chiral stationary phases in comparison with structurally related anion and cation exchangers. Employing polar-organic elution conditions, we observed an intramolecular counterion effect for acidic analytes which led to reduced retention times but did not impair enantiomer selectivities. Retention of amphoteric analytes is based on simultaneous double ion pairing of their charged functional groups with the acidic and basic sites of the zwitterionic selectors. A chiral center in the vicinity of the strong cation exchanger site is vital for chiral separations of bases. Sterically demanding side chains are beneficial for separations of free amino acids. Enantioseparations of free (un-derivatized) peptides were particularly successful in stationary phases with straight-chain alkanesulfonic acid sites, pointing to a beneficial influence of more flexible moieties. In addition, we observed pseudo-enantiomeric behavior of quinine and quinidine-derived chiral stationary phases facilitating reversal of elution orders for all analytes. © 2012 WILEY-VCH Verlag GmbH & Co.

    2007-01-01

    Pre-existing clinical research data sets exchanged in international epidemiology research often lack the elements needed to assess their suitability for use in multi-region meta-analyses or other clinical studies. While the missing information is generally known to local investigators, it is not contained in the files exchanged between sites. Instead, such content must be solicited by the study coordinating center though a series of lengthy phone and electronic communications: an informal process whose reproducibility and accuracy decays over time. This report describes a set of supplemental information needed to assess whether clinical research data from diverse research sites are truly comparable, and what metadata ("data about the data") should be preserved when a data set is archived for future use. We propose a structured Extensible Markup Language (XML) model that captures this information. The authors hope this model will be a first step towards preserving the metadata associated with clinical research data sets, thereby improving the quality of international data exchange, data archiving, and merged-data research using data collected in many different countries, languages and care settings.

    Full Text Available Objective. Describing the experience of patients with cystic fibrosis (CF and their families using the internet as a means for information, interaction and exchange of experiences with this disease. Methodology. A descriptive qualitative exploratory study was carried out in 2011. The subjects of the study were patients with CF and their parents or other family members contacted via e-mail on social networking websites. The requested information included the guiding question: ''Tell me about your experience on the internet as a means of information and exchange of experiences involving CF'', as well as demographic information and whether the respondent was the patient or a family member. Results. A total of 40 invitations were sent by email asking for information and 22 were accepted (55%. According to participants (15 patients and seven family members, the most widely used internet media were websites related to seeking information about CF. The use of internet was divided in three categories: 1 scientific and technical aspects, 2 emotional aspects, and c modes of disseminating information. Conclusion. The internet proved to be a medium of opinion formation which could eventually replace medical advice. It is necessary to establish criteria for constructing and monitoring information related to CF published on internet websites.

    This article presents a novel approach for understanding information exchange efficiency and its decay across hierarchies of modularity, from local to global, of the structural human brain connectome. Magnetic resonance imaging techniques have allowed us to study the human brain connectivity as a graph, which can then be analyzed using a graph-theoretical approach. Collectively termed brain connectomics, these sophisticated mathematical techniques have revealed that the brain connectome, like many networks, is highly modular and brain regions can thus be organized into communities or modules. Here, using tractography-informed structural connectomes from 46 normal healthy human subjects, we constructed the hierarchical modularity of the structural connectome using bifurcating dendrograms. Moving from fine to coarse (i.e., local to global) up the connectome's hierarchy, we computed the rate of decay of a new metric that hierarchically preferentially weighs the information exchange between two nodes in the same module. By computing "embeddedness"-the ratio between nodal efficiency and this decay rate, one could thus probe the relative scale-invariant information exchange efficiency of the human brain. Results suggest that regions that exhibit high embeddedness are those that comprise the limbic system, the default mode network, and the subcortical nuclei. This supports the presence of near-decomposability overall yet relative embeddedness in select areas of the brain. The areas we identified as highly embedded are varied in function but are arguably linked in the evolutionary role they play in memory, emotion and behavior. © 2015 Wiley Periodicals, Inc.

    In the frame of ECLISE EU FP6 project researchers, in close cooperation with local users of the water sector from the area of Crete, Greece, explored the ability of current climate information to develop and support local climate services water resources management and climate adaption policies. A wealth of climate modeling output ranging from event scale to decadal and centennial experiments, at temporal scales ranging from hourly to monthly, and at spatial scales from very high resolution regional climate models (2 km) to typical GCMs, were used in order to practically assess climate change impacts on water resources. Water resources availability issues analysed and facilitated within the project, focusing on estimates of the future water demands of the island, and comparing with seven "state of the art" CMIP5 simulations within COMBINE framework (under RCPs 2.6, 4.5 and 8.5) to estimate water resources availability, during 21st century. The ability of decadal GCM prediction experiments to reproduce basic hydrometeorological variables like precipitation and temperature for local impact studies, was also examined. Water availability for the whole island at basin scale until 2100 is estimated using the SAC-SMA rainfall-runoff model for a range of different scenarios of projected hydro-climatological regime, demand and supply potential. A robust signal of temperature increase and precipitation decrease is projected for all the pathways. Several messages could be extracted from this provider - user interaction such as the communication of basic concepts and uncertainties, user skepticism and feedback. The main user concern was the coarse spatial scale of climate information and in order to cope with this feedback a special case was framed in collaboration with the project modeling groups for demonstrating a high resolution climate modeling application of an extreme precipitation-flood event over the study area. This effort provided a realistic reproduction of the

    The Japanese scientific and technological information amounts to about 20% of the worldwide occurrence. According to the questionnaires about 70% of the respondants abroad experienced the use of literature written by Japanese within two months back from the date of answering. Japan is highly paid attention in a sense that she follows U.S. who is a leader in scientific and technological fields. Nevertherless only 5% of the total Japanese information has been introduced in major journals and international conferences of western world. Even information vendors have not provided information abroad actively. On the other hand it is necessary not only to provide information but also to promote mutual exchange of human resources concerning Southeast Asian countries. Considering the result of this questionnaires and trend in technology development the authors made the report on what international distribution of scientific and technological information should be. The outline of this report is described.

    Achieving interoperability between clinical electronic medical records (EMR) systems and cloud computing systems is challenging because of the lack of a universal reference method as a standard for information exchange with a secure connection. Here we describe an information exchange scheme using HTML5 microdata, where the standard semantic container is an HTML document. We embed HL7 messages describing laboratory test results in the microdata. We also annotate items in the clinical research report with the microdata. We mapped the laboratory test result data into the clinical research report using an HL7 selector specified in the microdata. This scheme can provide secure cooperation between the cloud-based service and the EMR system.

    Full Text Available A fast-paced process of hybridization of man and technology, organization and technology and society and technology is currently sweeping the world. This process requires a way of (scientific thinking that takes hybrid systems as the starting point. This way of thinking gives hybrid systems an increasing need to be interlinked, which enables them to exchange and share information through these links. This development of linking (hybrid systems to enable them to exchange and share information, can also be denoted as the realization of interoperability between (hybrid systems. Five principles from Luhmann’s systems theory can be of help to understand interoperability. Interoperability enables (hybrid systems to join random coalitions and networks. The network centric warfare concept is currently the basis for international efforts for the development and application of interoperability that would enable armed forces to act effectively and efficiently. In this paper is demonstrated what Luhmann’s system’s theory can learn us.

    Full Text Available The rapid development of electronic trading has significantly changed stock exchange markets. Electronic systems providing trading processes have defined a new stock market environment. Such a new environment requires trading process redefinition (generally defined as algorithmic trading, as well as redefinition of well known microstructure hypotheses. This paper conducts standard Hasbrouck’s (1991a, 1991b market microstructure time series analysis to examine adverse selection and information asymmetry issues on diverse liquidity leveled stocks listed on the London Stock Exchange, which is a market with a significant algorithmic trading share. Based on the results obtained from the considered sample, this paper suggests that the contribution of unexpected trade in the volatility of the efficient price is larger for intensively traded stocks, arguing that Hasbrouck’s (1991a, 1991b model recognizes algorithmic trading as an unexpected trade, i.e. as a trade caused by superior information.

    Health information exchange (HIE) systems facilitate access to patient information for a variety of health care organizations, end users, and clinical and organizational goals. While a complex intervention, organizations' usage of HIE is often conceptualized and measured narrowly. We sought to provide greater specificity to the concept of HIE as an intervention by formulating a typology of organizational HIE usage. We interviewed representatives of a regional health information organization and health care organizations actively using HIE information to change patient utilization and costs. The resultant typology includes three dimensions: user role, usage initiation, and patient set. This approach to categorizing how health care organizations are actually applying HIE information to clinical and business tasks provides greater clarity about HIE as an intervention and helps elucidate the conceptual linkage between HIE an organizational and patient outcomes.

    The idea of secure quantum information exchange (SQIE) [{\\it J. Phys. B: At. Mol. Opt. Phys.} 44, 115504 (2011)] is introduced for the secure exchange of single qubit information states between two legitimate users, Alice and Bob. In the present paper, we extend this original SQIE protocol by presenting a scheme, which enables the secure exchange of n-single qubit information states among the n nodes of a quantum network, with the aid of a special kind of 4$n$-qubit entangled state and the classical assistance of an extra participant Charlie. For experimental realization of our extended SQIE protocol, we suggest an efficient scheme for the generation of a special kind of 4n-qubit entangled state using the interaction between highly detuned $\\Lambda$-type three-level atoms and optical coherent field. Further, by discussing the various experimental parameters, we show that the special kind 4$n$-qubit entangled state can be generated with the presently available technology.

    1994-12-01

    An information management system was designed and implemented to interchange information between the DELPHI experiment at CERN and the monitoring/control system for the LEP (Large Electron Positron Collider) accelerator. This system is distributed and communicates with many different sources and destinations (LEP) using different types of communication. The system itself communicates internally via a communication system based on a publish-and-subscribe mechanism, DIM (Distributed Information Manager). The information gathered by this system is used for on-line as well as off-line data analysis. Therefore it logs the information to a database and makes it available to operators and users via DUI (DELPHI User Interface). The latter was extended to be capable of displaying "time-evolution" plots. It also handles a protocol, implemented using a finite state machine, SMI (State Management Interface), for (semi-)automatic running of the Data Acquisition System and the Slow Controls System.

    The global redistribution of pathogens, such as highly pathogenic avian influenza, has renewed interest in the connectivity of continental populations of birds. Populations of the Northern Pintail (Anas acuta) wintering in Japan and California are considered separate from a management perspective. We used data from band recoveries and population genetics to assess the degree of biological independence of these wintering populations. Distributions of recoveries in Russia of Northern Pintails originally banded during winter in North America overlapped with distributions of Northern Pintails banded during winter in Japan. Thus these allopatric wintering populations are partially sympatric during the breeding season. The primary areas of overlap were along the Chukotka and Kamchatka peninsulas in Russia. Furthermore, band recoveries demonstrated dispersal of individuals between wintering populations both from North America to Japan and vice versa. Genetic analyses of samples from both wintering populations showed little evidence of population differentiation. The combination of banding and genetic markers demonstrates that these two continental populations are linked by low levels of dispersal as well as likely interbreeding in eastern Russia. Although the levels of dispersal are inconsequential for population dynamics, the combination of dispersal and interbreeding represents a viable pathway for exchange of genes, diseases, and/or parasites. ??

    The Na/H exchanger regulatory factors, NHERF1 and NHERF2, are adapter proteins involved in targeting and assembly of protein complexes. The parathyroid hormone receptor (PTHR) interacts with both NHERF1 and NHERF2. The NHERF proteins toggle PTHR signaling from predominantly activation of adenylyl cyclase in the absence of NHERF to principally stimulation of phospholipase C when the NHERF proteins are expressed. We hypothesized that this signaling switch occurs at the level of the G protein. We measured G protein activation by [35S]GTPγS binding and Gα subtype-specific immunoprecipitation using three different cellular models of PTHR signaling. These studies revealed that PTHR interactions with NHERF1 enhance receptor-mediated stimulation of Gαq but have no effect on stimulation of Gαi or Gαs. In contrast, PTHR associations with NHERF2 enhance receptor-mediated stimulation of both Gαq and Gαi but decrease stimulation of Gαs. Consistent with these functional data, NHERF2 formed cellular complexes with both Gαq and Gαi, whereas NHERF1 was found to interact only with Gαq. These findings demonstrate that NHERF interactions regulate PTHR signaling at the level of G proteins and that NHERF1 and NHERF2 exhibit isotype-specific effects on G protein activation.

    The WaterML 2.0 Standards Working Group (SWG), working within the Open Geospatial Consortium (OGC) and in cooperation with the joint OGC-World Meteorological Organization (WMO) Hydrology Domain Working Group (HDWG), has developed an open standard for the exchange of water observation data; WaterML 2.0. The focus of the standard is time-series data, commonly generated from in-situ style monitoring. This is high value data for hydrological applications such as flood forecasting, environmental reporting and supporting hydrological infrastructure (e.g. dams, supply systems), which is commonly exchanged, but a lack of standards inhibits efficient reuse and automation. The process of developing WaterML required doing a harmonization analysis of existing standards to identify overlapping concepts and come to agreement on a harmonized definition. Generally the formats captured similar requirements, all with subtle differences, such as how time-series point metadata was handled. The in-progress standard WaterML 2.0 incorporates the semantics of the hydrologic information: location, procedure, and observations, and is implemented as an application schema of the Geography Markup Language version 3.2.1, making use of the OGC Observations & Measurements standards. WaterML2.0 is designed as an extensible schema to allow encoding of data to be used in a variety of exchange scenarios. Example areas of usage are: exchange of data for operational hydrological monitoring programs; supporting operation of infrastructure (e.g. dams, supply systems); cross-border exchange of observational data; release of data for public dissemination; enhancing disaster management through data exchange; and exchange in support of national reporting The first phase of WaterML2.0 focused on structural definitions allowing for the transfer of time-series, with less work on harmonization of vocabulary items such as quality codes. Vocabularies from various organizations tend to be specific and take time to

    This article illustrates a Web-based health information system that is comprised of specific information exchange standards related to health information for healthcare services in National Taiwan University Health System. Through multidisciplinary teamwork, medical and informatics experts collaborated and studied on system scope definition, standard selection challenges, system implementation barriers, system management outcomes, and further expandability of other systems. After user requirement analysis and prototyping, from 2005 to 2008, an online clinical decision support system with multiple functions of reminding and information push was implemented. It was to replace its original legacy systems and serve among the main hospital and three branches of 180-200 clinics and 7,500-8,000 patient visits per day. To evaluate the effectiveness of this system, user surveys were performed, which revealed that the average score of user satisfaction increased from 2.80 to 3.18 on a 4-point scale. Among the items, especially e-learning for training service, courtesy communications for system requests, and courtesy communications for system operations showed statistically significant improvement. From this study, the authors concluded that standardized information exchange technologies can be used to create a brand new enterprise value and steadily obtain more competitive advantages for a prestige healthcare system.

    The future of notifiable condition reporting in the United States is undergoing a transformation with the increasing development of Health Information Exchanges which support electronic data-sharing and -transfer networks and the wider adoption of electronic laboratory reporting. Communicable disease report forms originating in clinics are an important source of surveillance data for public health agencies. However, problems of poor data quality and delayed submission of reports to public health agencies are common. In addition, studies of barriers and facilitators to reporting have assumed that the primary reporter is the treating physician, although the extent to which a provider is involved in the reporting workflow is unclear. We sought to better understand the barriers to and burden of notifiable condition reporting from the perspectives of the three primary groups involved in reporting workflow: providers, clinic staff who bear the principal responsibility for reporting, and the public health workers who receive and process reports from clinics. In addition, we sought to situate these findings within the context of the future of notifiable disease reporting and the potential impacts of electronic lab and medical records on the surveillance system. Seven ambulatory care clinics and 3 public health agencies that are part of a Health Information Exchange in the state of Indiana, USA, participated in the study. Data were obtained from a survey of clinic physicians (N = 29), interviews with clinic reporters (N = 11), and interviews with public health workers (N = 9). Survey data were summarized descriptively and interview transcripts underwent qualitative analysis. In both clinics and public health agencies, the laboratory report initiates reporting workflow. Provider involvement with reporting primarily revolves around ordering medications to treat a condition confirmed by the lab result. In clinics, reporting is typically the responsibility of clinic

    Information exchange is critical to high-quality care transitions from hospitals to post-acute care (PAC) facilities. We conducted a survey to evaluate the completeness and timeliness of information transfer and communication between a tertiary-care academic hospital and its related PAC facilities. This was a cross-sectional Web-based 36-question survey of 110 PAC clinicians and staff representing 31 PAC facilities conducted between October and December 2013. We received responses from 71 of 110 individuals representing 29 of 31 facilities (65% and 94% response rates). We collapsed 4-point Likert responses into dichotomous variables to reflect completeness (sufficient vs insufficient) and timeliness (timely vs not timely) for information transfer and communication. Among respondents, 32% reported insufficient information about discharge medical conditions and management plan, and 83% reported at least occasionally encountering problems directly related to inadequate information from the hospital. Hospital clinician contact information was the most common insufficient domain. With respect to timeliness, 86% of respondents desired receipt of a discharge summary on or before the day of discharge, but only 58% reported receiving the summary within this time frame. Through free-text responses, several participants expressed the need for paper prescriptions for controlled pain medications to be sent with patients at the time of transfer. Staff and clinicians at PAC facilities perceive substantial deficits in content and timeliness of information exchange between the hospital and facilities. Such deficits are particularly relevant in the context of the increasing prevalence of bundled payments for care across settings as well as forthcoming readmissions penalties for PAC facilities. Targets identified for quality improvement include structuring discharge summary information to include information identified as deficient by respondents, completion of discharge summaries

    This study focuses on the situation of health information exchange (HIE) in the context of a nationwide network. It aims to create a security framework that can be implemented to ensure the safe transmission of health information across the boundaries of care providers in Malaysia and other countries. First, a critique of the major elements of nationwide health information networks is presented from the perspective of security, along with such topics as the importance of HIE, issues, and main approaches. Second, a systematic evaluation is conducted on the security solutions that can be utilized in the proposed nationwide network. Finally, a secure framework for health information transmission is proposed within a central cloud-based model, which is compatible with the Malaysian telehealth strategy. The outcome of this analysis indicates that a complete security framework for a global structure of HIE is yet to be defined and implemented. Our proposed framework represents such an endeavor and suggests specific techniques to achieve this goal.

    Improving the transfer of medication information between home care nurses and patient's general practitioners (GP) is assessed as essential for ensuring safe care. In this paper, we report on a Norwegian study in which we investigated how home care nurses experienced using standardised electronic messages in their communication with the GPs. Standardised electronic solutions were developed and implemented to resolve gaps in the medication information processes when patients received nursing care in their homes. Data was collected combining focus group interviews and individual interviews with nurses from home care in two municipalities in Norway. The data was analysed using systematic text condensation. We found that the nurses reported mostly advantages, but also some disadvantages regarding accuracy, consistency, availability and efficiency in the medication information process when they used standardised electronic messages. Efforts to refine the electronic messages to achieve better work processes and patient safety should be addressed.

    Biodiversity information is essential for understanding and managing the environment. However, identifying and providing the forms and types of biodiversity information most needed for research and decision-making is a significant challenge. While research needs and data gaps within particular topics or regions have received substantial attention, other information aspects such as data formats, sources, metadata, and information tools have received little. Focusing on the US southeast, a region of global biodiversity importance, this paper assesses the biodiversity information needs of environmental researchers, managers, and decision makers. Survey results of biodiversity information users' information needs, information-seeking behaviors and preferred information source attributes support previous conclusions that useful biodiversity information must be easily and quickly accessible, available in forms that allow integration and visualization and appropriately matched to users' needs. Survey results concerning additional information aspects suggest successful participation in both the creation and provision of biodiversity information include an increased focus on information search and other tools for data management, discovery, and description.

    Full Text Available The primary objective of this paper is to detect factors influencing the alignment of accounting information systems for firms in manufacturing sector listed on Tehran Stock Exchange. The concept of alignment has been investigated for many years, and strategic alignment plays essential role in increasing company performance. This paper investigates different levels of alignment and studies the factors, which influence alignment. More specifically, the work concentrates on the alignment between the requirements for accounting information (AIS requirements and the capacity of accounting systems (AIS capacity to build the information, in the specific context of manufacturing in Iran. The research sample consists of 216 companies over the period 2011-2007. The fit between these two sets was explored based on the moderation method and evidences indicate that AIS alignment in some firms was high. In addition, the relationship between the dependent variable and independent variables through multiple regressions yields a positive relationship between these variables.

    2014-01-01

    To provide a case report of barriers and promoters to implementing a health information exchange (HIE) tool that supports patient transfers between hospitals and skilled nursing facilities. A multi-disciplinary team conducted semi-structured telephone and in-person interviews in a purposive sample of HIE organizational informants and providers in New York City who implemented HIE to share patient transfer information. The researchers conducted grounded theory analysis to identify themes of barriers and promoters and took steps to improve the trustworthiness of the results including vetting from a knowledgeable study participant. Between May and October 2011, researchers recruited 18 participants: informaticians, healthcare administrators, software engineers, and providers from a skilled nursing facility. Subjects perceived the HIE tool's development a success in that it brought together stakeholders who had traditionally not partnered for informatics work, and that they could successfully share patient transfer information between a hospital and a skilled nursing facility. Perceived barriers included lack of hospital stakeholder buy-in and misalignment with clinical workflows that inhibited use of HIE-based patient transfer data. Participants described barriers and promoters in themes related to organizational, technical, and user-oriented issues. The investigation revealed that stakeholders could develop and implement health information technology that technically enables clinicians in both hospitals and skilled nursing facilities to exchange real-time information in support of patient transfers. User level barriers, particularly in the emergency department, should give pause to developers and implementers who plan to use HIE in support of patient transfers. Participants' experiences demonstrate how stakeholders may succeed in developing and piloting an electronic transfer form that relies on HIE to aggregate, communicate, and display relevant patient transfer

    In this work, we develop an approach to formation estimation by explicitly characterizing formation's system-theoretic attributes in terms of the underlying inter-spacecraft information-exchange network. In particular, we approach the formation observer/estimator design by relaxing the accessibility to the global state information by a centralized observer/estimator- and in turn- providing an analysis and synthesis framework for formation observers/estimators that rely on local measurements. The noveltyof our approach hinges upon the explicit examination of the underlying distributed spacecraft network in the realm of guidance, navigation, and control algorithmic analysis and design. The overarching goal of our general research program, some of whose results are reported in this paper, is the development of distributed spacecraft estimation algorithms that are scalable, modular, and robust to variations inthe topology and link characteristics of the formation information exchange network. In this work, we consider the observability of a spacecraft formation from a single observation node and utilize the agreement protocol as a mechanism for observing formation states from local measurements. Specifically, we show how the symmetry structure of the network, characterized in terms of its automorphism group, directly relates to the observability of the corresponding multi-agent system The ramification of this notion of observability over networks is then explored in the context of distributed formation estimation.

    The presence of multiple, institutionally independent but physically interconnected decision-makers is a distinctive features of many water resources systems, especially of transnational river basins. The adoption of a centralized approach to study the optimal operation of these systems, as mostly done in the water resources literature, is conceptually interesting to quantify the best achievable performance, but of little practical impact given the real political and institutional setting. Centralized management indeed assumes a cooperative attitude and full information exchange by the involved parties. However, when decision-makers belong to different countries or institutions, it is very likely that they act considering only their local objectives, producing global externalities that negatively impact on other objectives. In this work we adopt a Multi-Agent Systems framework, which naturally allows to represent a set of self-interested agents (decision-makers and/or stakeholders) acting in a distributed decision-making process. According to this agent-based approach, each agent represents a decision-maker, whose decisions are defined by an explicit optimization problem considering only the agent's local interests. In particular, this work assesses the role of information exchange and increasing level of cooperation among originally non-cooperative agents. The Zambezi River basin is used to illustrate the methodology: the four largest reservoirs in the basin (Ithezhithezhi, Kafue-Gorge, Kariba and Cahora Bassa) are mainly operated for maximizing the economic revenue from hydropower energy production with considerably negative effects on the aquatic ecosystem in the Zambezi delta due to the alteration of the natural flow regime. We comparatively analyse the ideal centralized solution and the current situation where all the decision-makers act independently and non-cooperatively. Indeed, although a new basin-level institution called Zambezi Watercourse Commission

    Objectives: Discharge planning is an important care process for managing transitions from the hospital to the community. It has been studied for >20 years, but few studies clarify the information exchanged between healthcare providers. This study aimed to describe nurses' experiences and perceptions of information exchange during the discharge planning process, focused on what, when and how information is exchanged between the hospital and primary healthcare. Method: A web-based census survey was used to collect data; the data were analyzed using descriptive statistics and chi-squared test. A questionnaire was distributed to 194 registered nurses (129 respondents) from a central county hospital and 67 district nurses (42 respondents) working in 13 primary healthcare centres. Results: The results show a significant difference between given and received information between the two groups. Both groups thought the information exchange worked best when all participants met at the discharge planning conference and that the electronic information system was difficult to use. Conclusion: This study shows difficulties knowing what patient-related information needs to give and not receiving the expected information. These results can be used to develop knowledge about roles, work tasks and needs to enhance the outcome of the process and the information exchanged.

    The objective of this qualitative study was to explore the concept of 'informed choice' in the context of self-directed support (SDS) for young people with disability in transition from child to adult services. SDS is a major policy initiative introduced by the Scottish government to promote personalised services by redefining the relationship between the citizen and the state regarding social care supports. Informed choice is one of the underpinning principles of the Social Care (Self-directed Support) (Scotland) Act 2013. The theoretical approach to the research study was that of critical realism and, in particular, realistic evaluation. The research design used multiple qualitative methods involving secondary analysis of archived qualitative longitudinal interview data, and primary interviews with nine individuals, representing a wide range of stakeholders in Scotland. The study developed hypotheses concerning the facilitators and barriers to informed choice for young people with disability. Factors facilitating informed choice included supportive family and professional networks, advocacy, accessible information and experiential knowledge. Barriers to informed choice were seen to be low expectations, poor collaboration between child and adult services and bureaucratic organisational cultures. SDS is entering the implementation phase of the policy cycle in Scotland and this study will inform emerging policy, practice and future research into personalisation for young people with disability in transition. In particular, the findings point to the need to involve young people with disability at an early stage in choice-making, and to foster self-advocacy skills and supportive social networks. Informed choice for young people with disability needs to be seen as a process over time involving both information and emotions and both need to be supported to ensure successful transitions.

  1. Assessing the value of cooperation and information exchange in large water resources systems by agent-based optimization

    2013-07-01

    Many large-scale water resources systems, especially in transboundary contexts, are characterized by the presence of several and conflicting interests and managed by multiple, institutionally independent decision makers. These systems are often studied adopting a centralized approach based on the assumption of full cooperation and information exchange among the involved parties. Such a perspective is conceptually interesting to quantify the best achievable performance but might have little practical impact given the real political and institutional setting. In this work, we propose a novel decision-analytic framework based on multiagent systems to model and analyze different levels of cooperation and information exchange among multiple decision makers. The Zambezi River basin is used as a case study. According to the proposed agent-based optimization approach, each agent represents a decision maker, whose decisions are defined by an explicit optimization problem considering only the agent's local interests. The economic value of information exchange is estimated comparing a noncooperative setting, where agents act independently, with the first basic level of cooperation, i.e., coordination, characterized by full information exchange. The economic value of cooperation is also estimated by comparison with the ideal, fully cooperative management of the system. Results show that coordination, obtained with complete information exchange, allows the downstream agents to better adapt to the upstream behaviors. The impact of information exchange depends on the objective considered, and we show coordination to be particularly beneficial to environmental interests.

    Background Rates of preventive and disease management services can be improved by providing automated alerts and reminders to primary care providers (PCPs) using of health information technology (HIT) tools. Methods: Using Adaptive Turnaround Documents (ATAD), an existing Health Information Exchange (HIE) infrastructure and office fax machines, we developed a Real Time Alert (RTA) system. RTA is a computerized decision support system (CDSS) that is able to deliver alerts to PCPs statewide for recommended services around the time of the patient visit. RTA is also able to capture structured clinical data from providers using existing fax technology. In this study, we evaluate RTA’s performance for alerting PCPs when their patients with asthma have an emergency room visit anywhere in the state. Results: Our results show that RTA was successfully able to deliver “just in time” patient-relevant alerts to PCPs across the state. Furthermore, of those ATADs faxed back and automatically interpreted by the RTA system, 35% reported finding the provided information helpful. The PCPs who reported finding information helpful also reported making a phone call, sending a letter or seeing the patient for follow up care. Conclusions: We have successfully demonstrated the feasibility of electronically exchanging important patient related information with the PCPs statewide. This is despite a lack of a link with their electronic health records. We have shown that using our ATAD technology, a PCP can be notified quickly of an important event such as a patient’s asthma related emergency room admission so further follow up can happen in near real time.

    Full Text Available This study examines the relationship between earnings management and information asymmetry based on some companies listed in Tehran Stock Exchange over the period of 2005-2010. The study only uses qualified samples by taking into account all limitations and necessary criteria. Based on the results of this survey, we can conclude that there is not a significant relationship between earning management and information asymmetry in Tehran Stock Exchange. There is also not a significant relationship between low or high earning management and information asymmetry. Estimated dividend announcement has information content and it can influence on information asymmetry. Finally, in Tehran Stock Exchange, there is information asymmetry and after dividend announcement, its value is more than before.

    The Federation of Earth Science Information Partners is a unique consortium of more than 90 organizations that collect, interpret and develop applications for remotely sensed Earth Observation Information. Included in the ESIP network are NASA, NOAA and USGS data centers, research universities, government research laboratories, supercomputer facilities, education resource providers, information technology innovators, nonprofit organizations and commercial enterprises. The consortium's work is dedicated to providing the most up-to-date, science-based information to researchers and decision-makers who are working to understand and address the environmental, economic and social challenges facing our planet. By increasing the use and usability of Earth observation data and linking it with decision-making tools, the Federation partners leverage the value of these important data resources for the betterment of society and our planet. To further the dissemination of Earth Science data, the Federation is developing the Earth Information Exchange (EIE). The EIE is a portal that will provide access to the vast information holdings of the members' organizations in one web-based location and will provides a robust marketplace in which the products and services needed to use and understand this information can be readily acquired. Since the Federation membership includes the federal government's Earth observing data centers, we believe that the impact of the EIE on Earth science research and education and environmental policy making will be profound. In the EIE, Earth observation data, products and services, are organized by the societal benefits categories defined by the international working group developing the Global Earth Observation System of Systems (GEOSS). The quality of the information is ensured in each of the Exchange's issue areas by maintaining working groups of issue area researchers and practitioners who serve as stewards for their respective communities.

    We aimed to develop a common health information exchange (HIE) platform that can provide integrated services for implementing the HIE infrastructure in addition to guidelines for participating in an HIE network in South Korea. By exploiting the Health Level 7 (HL7) Clinical Document Architecture (CDA) and Integrating the Healthcare Enterprise (IHE) Cross-enterprise Document Sharing-b (XDS.b) profile, we defined the architectural model, exchanging data items and their standardization, messaging standards, and privacy and security guidelines, for a secure, nationwide, interoperable HIE. We then developed a service-oriented common HIE platform to minimize the effort and difficulty of fulfilling the standard requirements for participating in the HIE network. The common platform supports open application program interfaces (APIs) for implementing a document registry, a document repository, a document consumer, and a master patient index. It could also be used for testing environments for the implementation of standard requirements. As the initial phase of implementing a nationwide HIE network in South Korea, we built a regional network for workers' compensation (WC) hospitals and their collaborating clinics to share referral and care record summaries to ensure the continuity of care for industrially injured workers, using the common HIE platform and verifying the feasibility of our technologies. We expect to expand the HIE network on a national scale with rapid support for implementing HL7 and IHE standards in South Korea.

    Full Text Available Solutions to the routing strategic conflict between noncooperative P2P overlay and ISP underlay go separate ways: hyperselfishness and cooperation. Unpredictable (possibly adverse impact of the hyperselfish topology awareness, which is adopted in both overlay routing and traffic engineering, has not been sufficiently studied in the literature. Topology-related information exchange in a cooperatively efficient way should be highlighted to alleviate the cross-layer conflict. In this paper, we first illustrate the hyperselfish weakness with two dynamic noncooperative game models in which hyperselfish overlay or underlay has to accept a suboptimal profit. Then we build a synergistic cost-saving (SC game model to reduce the negative effects of noncooperation. In the SC model, through information exchange, that is, the classified path-delay metrics for P2P overlay and peer locations for underlay, P2P overlay selects proximity as well as saving traffic transit cost for underlay, and ISP underlay adjusts routing to optimize network cost as well as indicating short delay paths for P2P. Simulations based on the real and generated topologies validate cost improvement by SC model and find a proper remote threshold value to limit P2P traffic from remote area, cross-AS, or cross-ISP.

    Full Text Available Analyzing social systems, particularly financial markets, using a complex network approach has become one of the most popular fields within econophysics. A similar trend is currently appearing within the econometrics and finance communities, as well. In this study, we present a state-of-the-artmethod for analyzing the structure and risk within stockmarkets, treating them as complex networks using model-free, nonlinear dependency measures based on information theory. This study is the first network analysis of the stockmarket in Shanghai using a nonlinear network methodology. Further, it is often assumed that markets outside the United States and Western Europe are inherently riskier. We find that the Chinese stock market is not structurally risky, contradicting this popular opinion. We use partial mutual information to create filtered networks representing the Shanghai stock exchange, comparing them to networks based on Pearson’s correlation. Consequently, we discuss the structure and characteristics of both the presented methods and the Shanghai stock exchange. This paper provides an insight into the cutting edge methodology designed for analyzing complex financial networks, as well as analyzing the structure of the market in Shanghai and, as such, is of interest to both researchers and financial analysts.

    HL7 (Health Level 7) is a standard developed for exchanging incompatible healthcare information generated from programs or devices among heterogenous medical information systems. At present, HL7 is growing as a global standard. However, the HL7 standard does not support effective methods for treating data from various medical sensors, especially from mobile sensors. As ubiquitous systems are growing, HL7 must communicate with various medical transducers. In the area of sensor fields, IEEE 1451 is a group of standards for controlling transducers and for communicating data from/to various transducers. In this paper, we present the possibility of interoperability between the two standards, i.e., HL7 and IEEE 1451. After we present a method to integrate them and show the preliminary results of this approach. PMID:20703604

    As patients receive medical care, their clinical history may be tracked and recorded by multiple electronic systems developed by independent vendors. Medical providers might use electronic health record (EHR) software tailored to the needs of trained medical personnel, whereas patients may interact with personal health records (PHR). The purpose of this essay is to identify the key interoperability issues associated with the information exchange between these two types of systems and offer an approach for enhancing interoperability.

    Improving Pollution Prevention and Waste Minimization Program (PP/WMIN) technologies, actions, and culture could be an important cost-cutting step for the US Department of Energy (DOE). Communicating ideas, concepts, process changes, and achievements is essential for the success of this program. The need to openly communicate ideas and concepts in a cost-effective manner is essential in an organization that has such diverse components as research and development, weapons production, and power generation. This approach is in contrast to the historic DOE culture developed within the cold war period in which compartmentalization, independence, and secrecy were stressed. DOE has now recognized that for any pollution prevention program to be successful, the many diverse elements of the organization must share information. Avenues for such information exchange are examined in this report.

    Full Text Available This paper investigates the validation of the Mixture of Distributions Hypothesis (MDH using trading volume and number of trades as contemporaneous proxies for information arrival in 15 sector indices of the Saudi Stock Exchange (Tadawul using the TGARCH model. Findings provide strong evidence for the validity of the MDH for the Saudi market. Volatility persistence decreases when the trading volume and the number of trades are included in the conditional variance equation. The most striking finding is that contemporaneous number of trades is a better proxy for information arrival than trading volume, interacting with volatility in a manner anticipated under the MDH. This can be attributed to the unique characteristic of the Saudi equity market where only domestic investors are allowed to execute trade transactions. Further, the results reveal that the leverage effect was amplified, indicating a more pronounced asymmetric effect of bad news on volatility.

    Although Biological Resource Centers (BRCs) traditionally have open catalogs of their holdings, it is quite cumbersome to access meta-information about microorganisms electronically due to the variety of access methods used by those catalogs. Therefore, we propose Microbiological Common Language (MCL), aimed at standardizing the electronic exchange of meta-information about microorganisms. Its application ranges from representing the online catalog of a single collection to accessing the results of StrainInfo integration and ad hoc use in other contexts. The abstract model of the standard precisely defines the elements of the standard, which enables implementation using a variety of representation technologies. Currently, XML and RDF/XML implementations are readily available. MCL is an open standard, and therefore greatly encourages input from the microbiological community.

    2013-09-01

    Full Text Available Background The trend towards hospitalist medicine can lead to disjointed patient care. Outpatient clinicians may be unaware of patients’ encounters with a disparate healthcare system. Electronic notifications to outpatient clinicians of patients’ emergency department (ED visits and inpatient admissions and discharges using health information exchange can inform outpatient clinicians of patients’ hospital-based events.Objective Assess outpatient clinicians’ impressions of a new, secure messaging-based, patient event notification system.Methods Twenty outpatient clinicians receiving notifications of hospital-based events were recruited and 14 agreed to participate. Using a semi-structured interview, clinicians were asked about their use of notifications and the impact on their practices.Results Nine of 14 interviewed clinicians (64% thought that without notifications, they would have heard about fewer than 10% of ED visits before the patient’s next visit. Nine clinicians (64% thought that without notifications, they would have heard about fewer than 25% of inpatient admissions and discharges before the patient’s next visit. Six clinicians (43% reported that they call the inpatient team more often because of notifications. Eight users (57% thought that notifications improved patient safety by increasing their awareness of the patients’ clinical events and their medication changes. Key themes identified were the importance of workflow integration and a desire for more clinical information in notifications.Conclusions The notification system is perceived by clinicians to be of value. These findings should instigate further message-oriented use of health information exchange and point to refinements that can lead to even greater benefits.

    To describe the design and deployment of health information technology to support implementation of mental health services policy requirements in the Veterans Health Administration (VHA). Using administrative and self-report survey data, we developed and fielded metrics regarding implementation of the requirements delineated in the VHA Uniform Mental Health Services Handbook. Finalized metrics were incorporated into 2 external facilitation-based quality improvement programs led by the VHA Mental Health Operations. To support these programs, tailored site-specific reports were generated. Metric development required close collaboration between program evaluators, policy makers and clinical leadership, and consideration of policy language and intent. Electronic reports supporting different purposes required distinct formatting and presentation features, despite their having similar general goals and using the same metrics. Health information technology can facilitate mental health policy implementation but must be integrated into a process of consensus building and close collaboration with policy makers, evaluators, and practitioners.

    To evaluate the complex dynamics involved in implementing electronic health information exchange (HIE) for public health reporting at a state health department, and to identify policy implications to inform similar implementations. Qualitative data were collected over 8 months from seven experts at New York State Department of Health who implemented web services and protocols for querying, receipt, and validation of electronic data supplied by regional health information organizations. Extensive project documentation was also collected. During group meetings experts described the implementation process and created reference modes and causal diagrams that the evaluation team used to build a preliminary model. System dynamics modeling techniques were applied iteratively to build causal loop diagrams representing the implementation. The diagrams were validated iteratively by individual experts followed by group review online, and through confirmatory review of documents and artifacts. Three casual loop diagrams captured well-recognized system dynamics: Sliding Goals, Project Rework, and Maturity of Resources. The findings were associated with specific policies that address funding, leadership, ensuring expertise, planning for rework, communication, and timeline management. This evaluation illustrates the value of a qualitative approach to system dynamics modeling. As a tool for strategic thinking on complicated and intense processes, qualitative models can be produced with fewer resources than a full simulation, yet still provide insights that are timely and relevant. System dynamics techniques clarified endogenous and exogenous factors at play in a highly complex technology implementation, which may inform other states engaged in implementing HIE supported by federal Health Information Technology for Economic and Clinical Health (HITECH) legislation.

  19. Combining personal with social information facilitates host defences and explains why cuckoos should be secretive

    2016-01-01

    Individuals often vary defences in response to local predation or parasitism risk. But how should they assess threat levels when it pays their enemies to hide? For common cuckoo hosts, assessing parasitism risk is challenging: cuckoo eggs are mimetic and adult cuckoos are secretive and resemble hawks. Here, we show that egg rejection by reed warblers depends on combining personal and social information of local risk. We presented model cuckoos or controls at a pair’s own nest (personal information of an intruder) and/or on a neighbouring territory, to which they were attracted by broadcasts of alarm calls (social information). Rejection of an experimental egg was stimulated only when hosts were alerted by both social and personal information of cuckoos. However, pairs that rejected eggs were not more likely to mob a cuckoo. Therefore, while hosts can assess risk from the sight of a cuckoo, a cuckoo cannot gauge if her egg will be accepted from host mobbing. Our results reveal how hosts respond rapidly to local variation in parasitism, and why it pays cuckoos to be secretive, both to avoid alerting their targets and to limit the spread of social information in the local host neighbourhood.

    Over the last decade, the emergence of social networking websites such as Facebook have revolutionized information dissemination and broadened opportunities to engage in discussions. In particular, having been widely adopted in the younger generation, the use of this medium has become more prevalent in health disorders such as scoliosis in the adolescent population. However, the quality of information on Facebook is unregulated and variable, which may mislead patients in their decision making. To document the various types of information available and assess the quality of information on Facebook discussion boards using recognized scoring systems. To evaluate the quality of information on the social network. A search for the keyword "scoliosis" on Facebook was performed and the first 100 pages generated were reviewed. SCSS and DISCERN score. Content analysis was performed on discussion boards and personal blogs. Two independent examiners evaluated each site according to scoliosis-specific content score (SCSS) and the DISCERN criteria, both previously used instruments to judge the quality of information on the Internet pertaining to scoliosis. The SCSS range from 0 to 32 (higher score better) and the DISCERN 16 to 80 (higher score better). Of the 100 sites reviewed, 33 were discussion boards and personal blogs. Of these, the overall average SCSS was 5.7 (SD 5.8, range 0-20) and the DISCERN was 22.5 (SD 7.6, range 16-45), indicating that using general scoring systems the quality of information provided was overall poor. Using recognized scoring systems to analyze Facebook pages used as discussion forums or blogs, we showed that the quality in general was poor. For modern practices to adapt to an era of information exchange via the social network, the orthopedic community should develop ways to incorporate the social media in future patient education.

    Full Text Available Abstract Introduction The Aintree intubating catheter (Cook® Medical Inc., Bloomington, IN, USA has been shown to successfully facilitate difficult intubations when other methods have failed. The Aintree intubating catheter (Cook® Medical Inc., Bloomington, IN, USA has a fixed length of 56 cm, and it has been suggested in the literature that it may be too short for safe use in patients who are tall. Case presentation We present the case of a 32-year-old, 180 cm tall Caucasian woman with a predicted difficult airway who presented to our facility for an emergency cesarean section. After several failed intubation attempts via direct laryngoscopy, an airway was established with a laryngeal mask airway. After delivery of a healthy baby, our patient's condition necessitated tracheal intubation. A fiber-optic bronchoscope loaded with an Aintree intubating catheter (Cook® Medical Inc., Bloomington, IN, USA was passed through the laryngeal mask airway into the trachea until just above the carina, but was too short to safely allow for the passage of an endotracheal tube. Conclusions We present a novel technique in which the Aintree intubating catheter (Cook® Medical Inc., Bloomington, IN, USA was replaced with a longer (100 cm exchange catheter, over which an endotracheal tube was passed successfully into the trachea.

  2. AMCP Partnership Forum: Enabling the Exchange of Clinical and Economic Information Pre-FDA Approval.

    Current federal laws and FDA regulations have significantly restricted the sharing of clinical and health economic information on biopharmaceuticals that have yet to receive FDA approval. Over the past several years, organizations that make health care coverage decisions, including those that set copayments, premiums, and formulary placement, have expressed a need for receiving this information before approval, as long as appropriate safeguards exist to prevent this information from reaching unintended entities. Population health decision makers have indicated that waiting until FDA approval is often too late for the critical planning, budgeting, and forecasting associated with health benefit design, especially given the recent influx of high-cost medications and scrutiny for better evaluation and preparation. Recognizing that securities laws restrict the disclosure of nonpublic information and may need to be amended, permissible early dissemination would allow population health decision makers to incorporate clinical and economic information for pipeline drugs or expanded indications into financial forecasting for the following year's plan. Access to this information is needed 12-18 months before FDA approval when organizations are deciding on terms of coverage and budgetary assumptions for state health insurance rate filings, Medicare and Medicaid bids, contracts with health care purchasers, and other financial arrangements. The need for exchange of clinical economic information before FDA approval was first introduced at a previous Academy of Managed Care (AMCP) forum in March 2016, which addressed section 114 of the Food and Drug Administration Modernization Act and the communication of such information after FDA approval. To address preapproval information specifically, AMCP convened a Partnership Forum on September 13-14, 2016. This forum included a diverse group of stakeholders representing managed care, the biopharmaceutical industry, providers, patients

    NASA Earth Sciences Division (ESD) has made great investments in the development and maintenance of data management systems and information technologies, to maximize the use of NASA generated Earth science data. With information management system infrastructure in place, mature and operational, very small delta costs are required to fully support data archival, processing, and data support services required by the recommended Decadal Study missions. This presentation describes the services and capabilities of the Goddard Space Flight Center (GSFC) Earth Sciences Data and Information Services Center (GES DISC) and the reusability for these future missions. The GES DISC has developed a series of modular, reusable data management components currently in use. They include data archive and distribution (Simple, Scalable, Script-based, Science [S4] Product Archive aka S4PA), data processing (S4 Processor for Measurements aka S4PM), data search (Mirador), data browse, visualization, and analysis (Giovanni), and data mining services. Information management system components are based on atmospheric scientist inputs. Large development and maintenance cost savings can be realized through their reuse in future missions.

    The potential for expanded communication among researchers, scholars, and students is supported by growth in the capabilities for electronic communication as well as expanding access to various forms of electronic interchange and computing capabilities. Increased possibilities for information exchange, collegial dialogue, collaboration, and access to remote resources exist as high-speed networks, increasingly powerful workstations, and large, multi-user computational facilities are more frequently linked and more commonly available. Numerous writers speak of the telecommunications revolution and its impact on the development and dissemination of knowledge and learning. One author offers the phrase 'Scholarly skywriting' to represent a new form of scientific communication that he envisions using electronic networks. In the United States (U.S.), researchers associated with the National Science Foundation (NSF) are exploring 'nationwide collaboratories' and 'digital collaboration.' Research supported by the U.S. National Aeronautics and Space Administration (NASA) points to a future where workstations with built-in audio, video monitors, and screen sharing protocols are used to support collaborations with colleagues located throughout the world. Instruments and sensors located worldwide will produce data streams that will be brought together, analyzed, and distributed as new findings. Researchers will have access to machines that can supply domain-specific information in addition to locator and directory assistance. New forms of electronic journals will emerge and provide opportunities for researchers and scientists to exchange information electronically and interactively in a range of structures and formats. Ultimately, the wide-scale use of these technologies in the dissemination of research results and the stimulation of collegial dialogue will change the way we represent and express our knowledge of the world. A new paradigm will evolve--perhaps a truly worldwide

    Full Text Available Information asymmetry is a situation in which one party in a transaction has more or superior information compared with another. This often happens in transactions where the seller knows more than the buyer does although the reverse also may happen. Potentially, this could be a harmful circumstance because one party can take advantage of the other party's lack of knowledge. In this paper, we examine the effect of information asymmetry on earning management. To test the research hypotheses, a sample of 47 companies listed in Tehran Stock Exchange over the period 2002-2008 based on panel data was taken. In these models, the presence or absence of effects models (fixed or random is reviewed and finally the best model is estimated. Inference is based on significant level or p-value, thus likely that any value or significance level of the test is less than 0.05 is rejected at the 95 percent confidence level. The result shows that the information asymmetry has some meaningful effects on earnings management.

    The combination of projected climate change and land use adds uncertainty to the long-term effectiveness of current management strategies. Managers need reliable information to adjust their strategies as population density increases. However they are currently overwhelmed by the diversity of available information and the multiplicity of sources. CBI's goal is to centralize and package effectively the usable information for land managers and for the general public in order to increase awareness and promote preparation for the challenges ahead. We are designing conservation planning atlases in Data Basin for a number of landscape conservation cooperatives to address this need. We are adding some user-friendly tools to specifically serve the available climate projections and land use data in a meaningful way. By working closely with a group of managers, our goal is to understand how consideration of these projections figures into the decision-making process and refine the ways we can deliver relevant metrics. We have been holding interviews to gather information and critical feedback on existing climate-related web pages and tools, providing us with benchmarks for improvement. As it turned out, the student-manager dialogue added a component of climate change education and awareness of available tools to the project. Through an iterative process we plan to continue this exchange and address the variety of issues managers continually have to face to maintain healthy ecosystems.

    Full Text Available Telecare Medical Information Systems (TMIS provide an effective way to enhance the medical process between doctors, nurses and patients. For enhancing the security and privacy of TMIS, it is important while challenging to enhance the TMIS so that a patient and a doctor can perform mutual authentication and session key establishment using a third-party medical server while the privacy of the patient can be ensured. In this paper, we propose an anonymous three-party password-authenticated key exchange (3PAKE protocol for TMIS. The protocol is based on the efficient elliptic curve cryptosystem. For security, we apply the pi calculus based formal verification tool ProVerif to show that our 3PAKE protocol for TMIS can provide anonymity for patient and doctor while at the same time achieves mutual authentication and session key security. The proposed scheme is secure and efficient, and can be used in TMIS.

    2014-01-01

    Health information exchange (HIE) is the secure, electronic transfer and/or accessibility of clinical data among healthcare providers. In the United States (US), the consent process for participation varies state to state. New York State (NYS) mandates written patient consent. The purpose of this study was to examine workflow and perceptions related to obtaining HIE consent in an HIV clinic. We used contextual inquiry to observe the HIE consent-related workflow of four registration clerks for a total of 4 hours on two weekdays and subsequently created a flow chart and sequence model diagram. Clerks were also interviewed and the resulting narrative data were coded into themes. Observational and interview data suggested that patient privacy/confidentiality/trust, high volume workflow, and multiple competing demands affect the patient HIE consent process. Additional qualitative data needs to be gathered from the perspectives of patients and clinicians about the HIE consent process.

    Notifying ambulatory providers when their patients visit the hospital is a simple concept but potentially a powerful tool for improving care coordination. A health information exchange (HIE) can provide automatic notifications to its members by building services on top of their existing infrastructure. NYCLIX, Inc., a functioning HIE in New York City, has developed a system that detects hospital admissions, discharges and emergency department visits and notifies their providers. The system has been in use since November 2010. Out of 63,305 patients enrolled 6,913 (11%) had one or more events in the study period and on average there were 238 events per day. While event notifications have a clinical value, their use also involves non-clinical care coordination; new workflows should be designed to incorporate a broader care team in their use. This paper describes the user requirements for the notification system, system design, current status, lessons learned and future directions. PMID:23304336

    The rapid growing of online purchasing of information products poses challenges of how to preserve the customer's privacy during the online transactions. The current widely used way of online shopping does not consider the customer's privacy protection. It exposes the customer's sensitive information unnecessarily. We propose a new five-party implementation model called 5PAPS that provides much enhanced protection of the customer's privacy. The model combines the advantages of the e-cash techniques, the mix technique, the anonymous-honoring merchant model, and the anonymity-protecting payment gateway model. It is aimed for protecting the customer's anonymity in all applicable aspects. Security and anonymity issues of the model have been analyzed. The results show that the model is robust against varieties of common attacks and the customer's anonymity can be protected even in the presence of some collusion among the parties involved in the transactions. Experimental prototyping of the essential parts yields partial validation of the practical nature of the 5PAPS model, and it has also produced reliable estimates of the storage and messaging volume requirements present in sizable purchasing systems.

    Limited research exists on nursing home information technologies, such as health information exchange (HIE) systems. Capturing the experiences of early HIE adopters provides vital information about how these systems are used. In this study, we conduct a secondary analysis of qualitative data captured during interviews with 15 nursing home leaders representing 14 nursing homes in the midwestern United States that are part of the Missouri Quality Improvement Initiative (MOQI) national demonstration project. The interviews were conducted as part of an external evaluation of the HIE vendor contracting with the MOQI initiative with the purpose of understanding the challenges and successes of HIE implementation, with a particular focus on Direct HIE services. Emerging themes included (1) incorporating HIE into existing work processes, (2) participation inside and outside the facility, (3) appropriate training and retraining, (4) getting others to use the HIE, (5) getting the HIE operational, and 6) putting policies for technology into place. Three essential areas should be considered for nursing homes considering HIE adoption: readiness to adopt technology, availability of technology resources, and matching of new clinical workflows.

    In fMRI analyses, the posterior parietal cortex (PPC) is particularly active during the successful retrieval of episodic memory. To delineate the neural correlates of episodic retrieval more succinctly, we compared retrieval of recently learned spatial locations (photographs of buildings) with retrieval of previously familiar locations (photographs of familiar campus buildings). Episodic retrieval of recently learned locations activated a circumscribed region within the ventral PPC (anterior angular gyrus and adjacent regions in the supramarginal gyrus) as well as medial PPC regions (posterior cingulated gyrus and posterior precuneus). Retrieval of familiar locations activated more posterior regions in the ventral PPC (posterior angular gyrus, LOC) and more anterior regions in the medial PPC (anterior precuneus and retrosplenial cortex). These dissociable effects define more precisely PPC regions involved in the retrieval of recent, contextually bound information as opposed to regions involved in other processes, such as visual imagery, scene reconstruction, and self-referential processing.

    Expression of the large extracellular glycan, polysialic acid (polySia), is restricted in the adult, to brain regions exhibiting high levels of plasticity or remodeling, including the hippocampus, prefrontal cortex, and the nucleus of the solitary tract (NTS). The NTS, located in the dorsal brainstem, receives constant viscerosensory afferent traffic as well as input from central regions controlling sympathetic nerve activity, respiration, gastrointestinal functions, hormonal release, and behavior. Our aims were to determine the ultrastructural location of polySia in the NTS and the functional effects of enzymatic removal of polySia, both in vitro and in vivo polySia immunoreactivity was found throughout the adult rat NTS. Electron microscopy demonstrated polySia at sites that influence neurotransmission: the extracellular space, fine astrocytic processes, and neuronal terminals. Removing polySia from the NTS had functional consequences. Whole-cell electrophysiological recordings revealed altered intrinsic membrane properties, enhancing voltage-gated K(+) currents and increasing intracellular Ca(2+) Viscerosensory afferent processing was also disrupted, dampening low-frequency excitatory input and potentiating high-frequency sustained currents at second-order neurons. Removal of polySia in the NTS of anesthetized rats increased sympathetic nerve activity, whereas functionally related enzymes that do not alter polySia expression had little effect. These data indicate that polySia is required for the normal transmission of information through the NTS and that changes in its expression alter sympathetic outflow. polySia is abundant in multiple but discrete brain regions, including sensory nuclei, in both the adult rat and human, where it may regulate neuronal function by mechanisms identified here.SIGNIFICANCE STATEMENT All cells are coated in glycans (sugars) existing predominantly as glycolipids, proteoglycans, or glycoproteins formed by the most complex form of

    Science.gov (United States)

    2013-01-01

    Background Decisions regarding health systems are sometimes made without the input of timely and reliable evidence, leading to less than optimal health outcomes. Healthcare organizations can implement tools and infrastructures to support the use of research evidence to inform decision-making. Objectives The purpose of this study was to profile the supports and instruments (i.e., programs, interventions, instruments or tools) that healthcare organizations currently have in place and which ones were perceived to facilitate evidence-informed decision-making. Methods In-depth semi-structured telephone interviews were conducted with individuals in three different types of positions (i.e., a senior management team member, a library manager, and a ‘knowledge broker’) in three types of healthcare organizations (i.e., regional health authorities, hospitals and primary care practices) in two Canadian provinces (i.e., Ontario and Quebec). The interviews were taped, transcribed, and then analyzed thematically using NVivo 9 qualitative data analysis software. Results A total of 57 interviews were conducted in 25 organizations in Ontario and Quebec. The main findings suggest that, for the healthcare organizations that participated in this study, the following supports facilitate evidence-informed decision-making: facilitating roles that actively promote research use within the organization; establishing ties to researchers and opinion leaders outside the organization; a technical infrastructure that provides access to research evidence, such as databases; and provision and participation in training programs to enhance staff’s capacity building. Conclusions This study identified the need for having a receptive climate, which laid the foundation for the implementation of other tangible initiatives and supported the use of research in decision-making. This study adds to the literature on organizational efforts that can increase the use of research evidence in decision

    The Virtual Lifetime Electronic Record (VLER) Health program provides the Veterans Health Administration (VHA) a framework whereby VHA providers can access the veterans' electronic health record information to coordinate healthcare across multiple sites of care. As an early adopter of VLER, the Indianapolis VHA and Regenstrief Institute implemented a regional demonstration program involving bi-directional health information exchange (HIE) between VHA and non-VHA providers.The aim of the study is to determine whether implementation of VLER HIE reduces 1 year VHA medical costs.A cohort evaluation with a concurrent control group compared VHA healthcare costs using propensity score adjustment. A CHEERs compliant checklist was used to conduct the cost evaluation.Patients were enrolled in the VLER program onsite at the Indianapolis VHA in outpatient clinics or through the release-of-information office.VHA cost data (in 2014 dollars) were obtained for both enrolled and nonenrolled (control) patients for 1 year prior to, and 1 year after, the index date of patient enrollment.There were 6104 patients enrolled in VLER and 45,700 patients in the control group. The annual adjusted total cost difference per patient was associated with a higher cost for VLER enrollees $1152 (95% CI: $807-1433) (P < 0.01) (in 2014 dollars) than VLER nonenrollees.Short-term evaluation of this demonstration project did not show immediate reductions in healthcare cost as might be expected if HIE decreased redundant medical tests and treatments. Cost reductions from shared health information may be realized with longer time horizons.

  2. Linking attentional processes and conceptual problem solving: Visual cues facilitate the automaticity of extracting relevant information from diagrams

    Full Text Available This study investigated links between lower-level visual attention processes and higher-level problem solving. This was done by overlaying visual cues on conceptual physics problem diagrams to direct participants’ attention to relevant areas to facilitate problem solving. Participants (N = 80 individually worked through four problem sets, each containing a diagram, while their eye movements were recorded. Each diagram contained regions that were relevant to solving the problem correctly and separate regions related to common incorrect responses. Problem sets contained an initial problem, six isomorphic training problems, and a transfer problem. The cued condition saw visual cues overlaid on the training problems. Participants’ verbal responses were used to determine their accuracy. The study produced two major findings. First, short duration visual cues can improve problem solving performance on a variety of insight physics problems, including transfer problems not sharing the surface features of the training problems, but instead sharing the underlying solution path. Thus, visual cues can facilitate re-representing a problem and overcoming impasse, enabling a correct solution. Importantly, these cueing effects on problem solving did not involve the solvers’ attention necessarily embodying the solution to the problem. Instead, the cueing effects were caused by solvers attending to and integrating relevant information in the problems into a solution path. Second, these short duration visual cues when administered repeatedly over multiple training problems resulted in participants becoming more efficient at extracting the relevant information on the transfer problem, showing that such cues can improve the automaticity with which solvers extract relevant information from a problem. Both of these results converge on the conclusion that lower-order visual processes driven by attentional cues can influence higher-order cognitive processes

  3. Tax Information Exchange Influence on Czech Based Companies’ Behavior in Relation to Tax Havens

    2017-01-01

    Full Text Available In recent years, borders between countries have been opened gradually thanks to globalization, which is reflected in minimal barriers to the movement of persons and capital. This situation could be potentially abused by taxpayers willing to shift the capital to preferential tax jurisdictions. Due to facts aforementioned, several instruments for tax administrators have been introduced. Bilateral and multilateral instruments are concluded with particular countries for the purpose of obtaining information about foreign residents staying abroad but also to avoid double taxation or double non‑taxation. In recent years there has been an increased number of companies in the Czech Republic whose owners come from preferential tax jurisdiction from 12,676 up to 13,167. This paper is focused on the Czech taxpayers’ reaction on concluding agreements concerning exchange of information in tax matters with preferential tax jurisdictions, the so‑called “Tax havens”. The Difference‑in‑Differences Method was carried out to predict the taxpayers’ behavior. The model shows that the agreements work well as a preventive tool. If the Czech Republic concludes the agreement with the tax haven, the taxpayers lose their anonymity. This results in their relocation into tax havens that are not covered by the agreement in order to keep their anonymity.

    Full Text Available The new styles and ways of life lead to greater use of wireless networks, the mobile device being a tool for data transmission, which are susceptible to threats in the transmission channels in the network. IT security plays a very important role in guaranteeing the availability, privacy and integrity of information, one of the techniques that helps in this task is cryptography, whose foundation is to transform a message so that it is unintelligible except for those who have the Key to decipher it. The research focuses on the use of the RSA algorithm between mobile devices, the encrypted data is sent through communication channels called threads that through formulas and processes executed on the server, will help to execute the encryption and decryption of the data. To carry it out, a prototype for the exchange of data between mobile devices wirelessly was designed and implemented, conducting performance tests with three nodes to improve the security. The results show the efficiency of the algorithm and additionally its functionality, the times of encryption and decryption are fast against the sending of information without any method or algorithm used.

    Vapor intrusion (VI) is a term used to describe indoor air (IA) contamination that occurs due to the migration of chemical vapors in the soil and groundwater. The overall vapor transport process depends on several factors such as contaminant source characteristics, subsurface conditions, building characteristics, and general site conditions. However, the classic VI conceptual model does not adequately account for the physics of airflow around and inside a building and does not account for chemical emissions from alternative "preferential" pathways (e.g. sewers and other utility connections) into IA spaces. This mini-review provides information about recent research related to building air exchange rates (AERs) and alternative pathways to improve the accuracy of VI exposure risk assessment practices. First, results from a recently published AER study for residential homes across the United States (US) are presented and compared to AERs recommended by the US Environmental Protection Agency (USEPA). The comparison shows considerable differences in AERs when season, location, building age, and other factors are considered. These differences could directly impact VI assessments by influencing IA concentration measurements. Second, a conceptual model for sewer gas entry into buildings is presented and a summary of published field studies is reported. The results of the field studies suggest that alternative pathways for vapors to enter indoor spaces warrant consideration. Ultimately, the information presented in this mini-review can be incorporated into a multiple-lines-of-evidence approach for assessing site-specific VI exposure risks.

    Abstract This paper argues that knowledge sharing can be conceptualized as different situations of exchange in which individuals relate to each other in different ways, involving different rules, norms and traditions of reciprocity regulating the exchange. The main challenge for facilitating knowledge sharing is to ensure that the exchange is seen as equitable for the parties involved, and by viewing the problems of knowledge sharing as motivational problems situated in different organization...

    Efficient online discovering and applying geospatial information resources (GIRs) is critical in Earth Science domain as while for cross-disciplinary applications. However, to achieve it is challenging due to the heterogeneity, complexity and privacy of online GIRs. In this article, GeoSquare, a collaborative online geospatial information sharing and geoprocessing platform, was developed to tackle this problem. Specifically, (1) GIRs registration and multi-view query functions allow users to publish and discover GIRs more effectively. (2) Online geoprocessing and real-time execution status checking help users process data and conduct analysis without pre-installation of cumbersome professional tools on their own machines. (3) A service chain orchestration function enables domain experts to contribute and share their domain knowledge with community members through workflow modeling. (4) User inventory management allows registered users to collect and manage their own GIRs, monitor their execution status, and track their own geoprocessing histories. Besides, to enhance the flexibility and capacity of GeoSquare, distributed storage and cloud computing technologies are employed. To support interactive teaching and training, GeoSquare adopts the rich internet application (RIA) technology to create user-friendly graphical user interface (GUI). Results show that GeoSquare can integrate and foster collaboration between dispersed GIRs, computing resources and people. Subsequently, educators and researchers can share and exchange resources in an efficient and harmonious way.

    Pediatric patients with health conditions requiring follow-up typically depend on a caregiver to mediate at least part of the necessary two-way communication with health care providers on their behalf. Health information technology (HIT) and its subset, information communication technology (ICT), are increasingly being applied to facilitate communication between health care provider and caregiver in these situations. Awareness of the extent and nature of published research involving HIT interventions used in this way is currently lacking. This scoping review was designed to map the health literature about HIT used to facilitate communication involving health care providers and caregivers (who are usually family members) of pediatric patients with health conditions requiring follow-up. Terms relating to care delivery, information technology, and pediatrics were combined to search MEDLINE, EMBASE, and CINAHL for the years 1996 to 2008. Eligible studies were selected after three rounds of duplicate screening in which all authors participated. Data regarding patient, caregiver, health care provider, HIT intervention, outcomes studied, and study design were extracted and maintained in a Microsoft Access database. Stage of research was categorized using the UK's Medical Research Council (MRC) framework for developing and evaluating complex interventions. Quantitative and qualitative descriptive summaries are presented. We included 104 eligible studies (112 articles) conducted in 17 different countries and representing 30 different health conditions. The most common conditions were asthma, type 1 diabetes, special needs, and psychiatric disorder. Most studies (88, 85%) included children 2 to 12 years of age, and 73 (71%) involved home care settings. Health care providers operated in hospital settings in 96 (92%) of the studies. Interventions featured 12 modes of communication (eg, Internet, intranets, telephone, video conferencing, email, short message service [SMS], and

    Maintaining continuity of patient care can be difficult during transitions between care settings, when quality of care and patient safety are at risk. We sought to understand the role of inter-provider documentation and information exchange across successive care settings for complex, older patients. Data were gathered as part of a multi-site ethnographic study that followed 23 older post-surgical hip fracture patients across multiple care transitions. Documentation and information exchange help build a "picture" of complex patients, but care continuity is challenged by late, missing or unnecessary information, duplicated assessments and lack of interoperability of electronic systems. This study demonstrates the importance of appropriate documentation in the transition process, but points to the need for comprehensive system-level solutions which standardize information collection and sharing along the continuum of care.

    Full Text Available Abstract Background The provision of residential aged care is underpinned by information, and is reliant upon systems that adequately capture and effectively utilise and communicate this information. The aim of this study was to explicate and quantify the volume and method by which information is collected, exchanged within facilities and with external providers, and retrieved from facility information systems and hospitals. Methods A survey of staff (n = 119, including managers, health informatics officers (HIOs, quality improvement staff, registered nurses (RNs, enrolled nurses (ENs/endorsed enrolled nurses (EENs and assistants in nursing (AINs was carried out in four residential aged care facilities in New South Wales and Victoria, Australia. Sites varied in size and displayed a range of information technology (IT capabilities. The survey investigated how and by whom information is collected, retrieved and exchanged, and the frequency and amount of time devoted to these tasks. Descriptive analysis was performed using SPSS, and open responses to questions were coded into key themes. Results Staff completed a median of six forms each, taking a median of 30 min per shift. 68.8% of staff reported transferring information from paper to a computer system, which took a median of 30 min per shift. Handover and face-to-face communication was the most frequently used form of information exchange within facilities. There was a large amount of faxing and telephone communication between facility staff and General Practitioners and community pharmacists, with staff reporting sending a median of 2 faxes to pharmacy and 1.5 faxes to General Practitioners, and initiating 2 telephone calls to pharmacies and 1.5 calls to General Practitioners per shift. Only 38.5% of respondents reported that they always had information available at the point-of-care and only 35.4% of respondents reported that they always had access to hospital stay information of residents

    Although health information exchanges (HIE) have existed since their introduction by President Bush in his 2004 State of the Union Address, and despite monetary incentives earmarked in 2009 by the health information technology for economic and clinical health (HITECH) Act, adoption of HIE has been sparse in the United States. Research has been conducted to explore the concept of HIE and its benefit to patients, but viable business plans for their existence are rare, and so far, no research has been conducted on the dynamic nature of barriers over time. The aim of this study is to map the barriers mentioned in the literature to illustrate the effect, if any, of barriers discussed with respect to the HITECH Act from 2009 to the early months of 2014. We conducted a systematic literature review from CINAHL, PubMed, and Google Scholar. The search criteria primarily focused on studies. Each article was read by at least two of the authors, and a final set was established for evaluation (n=28). The 28 articles identified 16 barriers. Cost and efficiency/workflow were identified 15% and 13% of all instances of barriers mentioned in literature, respectively. The years 2010 and 2011 were the most plentiful years when barriers were discussed, with 75% and 69% of all barriers listed, respectively. The frequency of barriers mentioned in literature demonstrates the mindfulness of users, developers, and both local and national government. The broad conclusion is that public policy masks the effects of some barriers, while revealing others. However, a deleterious effect can be inferred when the public funds are exhausted. Public policy will need to lever incentives to overcome many of the barriers such as cost and impediments to competition. Process improvement managers need to optimize the efficiency of current practices at the point of care. Developers will need to work with users to ensure tools that use HIE resources work into existing workflows.

  15. A Proposal for Establishing a Free Market Basis for Plant Genome Information Exchange

    Energy Technology Data Exchange (ETDEWEB)

    Slezak, T.

    2001-09-26

    The current situation of genomics information exchange is reminiscent of some Third World cities, where residents despair they will ever get official utility service and therefore tap into power, phone, and gas sources with makeshift connections. Thus, each genomics grant spawns yet another idiosyncratic Web site, with makeshift links to whatever random Web sites the PI is most familiar with. There are few standards for semantics of data, and fewer standards for automating the interchange or integration of these autonomous Web sites. The US Plant Genome Initiative (PGI) has been enthusiastic contributor to this proliferation of chaotic Web sites, but to its credit it appears to be the first major program to attempt to find a solution. Some of us from the earliest days of the Human Genome Program have been acutely aware of the problems of genomic data integration, since long before the Web appeared and made the problem exponentially harder to resolve. We have seen large scale attempts, and subsequent failures or inadequacies, of many potential solution approaches (i.e., database federation, classical data warehousing, centralized data, etc.) and believe we know at least some of the reasons they still remain inadequate. It is our opinion that the only solution that has a chance of succeeding is one that considers the overall economics of genomics data production, sharing, and integration. We believe that attempting to create a kind of Free Market for data created under the Plant Genome Initiative will represent the most practical, powerful, and cost-effective approach to dealing with the broad range of plant genome information that has been unleashed.

    Extension of the image network within radiotherapy departments provides the technical infrastructure which is made necessary by the rapid evolution of techniques in the field of diagnosis and treatment in radiotherapy. The system is aimed at managing the whole set of data (textual data and images) that are needed for planning and control of treatments. The radiotherapy network addresses two objectives: managing both the information necessary for treatment planning (target volumes definition, planning dosimetry) and the control of all parameters involved during the patient's treatment under the treatment unit. The major challenge is to improve the quality of treatment. Multimodal imaging is a major advance as it allows the use of new dosimetry and simulation techniques. The need for standards to exchange medical imaging information is now recognized by all the institutions and a majority of users and manufacturers. It is widely accepted that the lack of standard has been one of the fundamental obstacles in the deployment of operational "Picture Archiving Communication Systems". The International Standard Organisation Open System Interconnection model is the standard reference mode used to describe network protocols. The network is based on the Ethernet and TCP/IP protocol that provides the means to interconnect imaging devices and workstations dedicated to specific image processing or machines used in radiotherapy. The network uses Ethernet cabled on twisted-pair (10 BaseT) or optical fibres in a star-shaped physical layout. Dicom V3.0 supports fundamental network interactions: transfer of images (computerized tomography magnetic resonance imaging query and retrieve of images), printing on network attached cameras, support of HIS/RIS related interfacing and image management. The supplement to the Dicom standard, Dicom RT, specifies five data objects known in Dicom as Information Object Definition for relevant radiotherapy. Dicom RT objects can provide a mean for

    Mutual information exchange at international levels is important for practical application of global environment preservation technologies, whereas the APEC Virtual Center was established in fiscal 1997. Fiscal 1998 has discussed the future functions of the Virtual Center, and carried out the following matters to improve the functions and achieve its stable operation. Discussions were given on common use with the centers of other countries and regions of the specifications of classification systems for information areas and provided information that are provided by the Virtual Center. Visits were made to sub-managing countries and regions for smooth operation of the study groups, and opinions were exchanged. Visits were made to coordinators and contact points established in each country and region when the Center was founded in fiscal 1997. A visit was made to the U.S. Environmental Protection Agency to exchange opinions on coordination measures with the Cleaner Production Strategy of the U.S.A. being a project similar to the subject project. In order to strengthen the Japan's Center, attempts were made to expand the linking information to wider scope. Special pages publishing concentratedly the items of information that the users are interested were prepared as part of the information provision. (NEDO)

    The EKO-4.2 project involves investigating approaches to setting up a new reliable system based on computer internet technology for exchange of information between the Nordic countries. According to the project plans this information exchange is to be based on bulletin board systems in the different countries. It was required that the system should not set any restriction of type of data or information to be exchanged, nor should it involve any standardization of data, and above all, it was not intended as an alert system. A bulletin board system is passive in the sense that no information is actually sent, instead it is the receiver who is responsible for approaching the information and transferring it to own system. This feature makes the system unsuitable for alert purposes. Since a potential system will have to be implemented by the authorities in the respective countries, the first part of the project was to survey their interest and emphasis. This was done in meetings in the different countries. The conclusion from those meetings was an overall interest in establishing a system as described, and several requirements concerning security and reliability of the system were proposed. The implication of the requirements by the authorities is discussed and a practical solution of an information exchange system based on the World Wide Web (WWW), the File Transfer Protocol (FTP), and the Internet is outlined. The continuation of the project must be based on operable servers in the different countries, whose configuration and connection with the local network are the responsibility of the institution owning the server. The selected system will depend on hardware and on the overall security policy of the institution involved. It is proposed that further work concentrates on a general testing of the system, standardizing of server user interfaces and testing of encryption software for transfer of passwords. (au)

    Health systems worldwide struggle to identify, adopt, and implement in a timely and system-wide manner the best-evidence-informed-policy-level practices. Yet, there is still only limited evidence about individual and institutional best practices for fostering the use of scientific evidence in policy-making processes The present project is the first national-level attempt to (1) map and structurally analyze-quantitatively-health-relevant policy-making networks that connect evidence production, synthesis, interpretation, and use; (2) qualitatively investigate the interaction patterns of a subsample of actors with high centrality metrics within these networks to develop an in-depth understanding of evidence circulation processes; and (3) combine these findings in order to assess a policy network's "absorptive capacity" regarding scientific evidence and integrate them into a conceptually sound and empirically grounded framework. The project is divided into two research components. The first component is based on quantitative analysis of ties (relationships) that link nodes (participants) in a network. Network data will be collected through a multi-step snowball sampling strategy. Data will be analyzed structurally using social network mapping and analysis methods. The second component is based on qualitative interviews with a subsample of the Web survey participants having central, bridging, or atypical positions in the network. Interviews will focus on the process through which evidence circulates and enters practice. Results from both components will then be integrated through an assessment of the network's and subnetwork's effectiveness in identifying, capturing, interpreting, sharing, reframing, and recodifying scientific evidence in policy-making processes. Knowledge developed from this project has the potential both to strengthen the scientific understanding of how policy-level knowledge transfer and exchange functions and to provide significantly improved advice

    2014-12-01

    Telecare medicine information systems provide a communicating platform for accessing remote medical resources through public networks, and help health care workers and medical personnel to rapidly making correct clinical decisions and treatments. An authentication scheme for data exchange in telecare medicine information systems enables legal users in hospitals and medical institutes to establish a secure channel and exchange electronic medical records or electronic health records securely and efficiently. This investigation develops an efficient and secure verified-based three-party authentication scheme by using extended chaotic maps for data exchange in telecare medicine information systems. The proposed scheme does not require server's public keys and avoids time-consuming modular exponential computations and scalar multiplications on elliptic curve used in previous related approaches. Additionally, the proposed scheme is proven secure in the random oracle model, and realizes the lower bounds of messages and rounds in communications. Compared to related verified-based approaches, the proposed scheme not only possesses higher security, but also has lower computational cost and fewer transmissions.

    Wearable computing devices are starting to change the way users interact with computers and the Internet. Among them, Google Glass includes a small screen located in front of the right eye, a camera filming in front of the user and a small computing unit. Google Glass has the advantage to provide online services while allowing the user to perform tasks with his/her hands. These augmented glasses uncover many useful applications, also in the medical domain. For example, Google Glass can easily provide video conference between medical doctors to discuss a live case. Using these glasses can also facilitate medical information search by allowing the access of a large amount of annotated medical cases during a consultation in a non-disruptive fashion for medical staff. In this paper, we developed a Google Glass application able to take a photo and send it to a medical image retrieval system along with keywords in order to retrieve similar cases. As a preliminary assessment of the usability of the application, we tested the application under three conditions (images of the skin; printed CT scans and MRI images; and CT and MRI images acquired directly from an LCD screen) to explore whether using Google Glass affects the accuracy of the results returned by the medical image retrieval system. The preliminary results show that despite minor problems due to the relative stability of the Google Glass, images can be sent to and processed by the medical image retrieval system and similar images are returned to the user, potentially helping in the decision making process.

    Tightly related subsystems in a HIS have to exchange medical data flexibly by the data object rather than by the battery of the data. We developed a CPR subsystem based on Common Object Request Broker Architecture (CORBA) that retrieves and stores clinical information in the object-oriented database via Internet Intra-ORB Protocol (IIOP). The system is hybridized with the legacy HIS applications on the client terminals. We believe that our solution and the experiences will contribute to the future CORBA-based environment in which computerized patient information is shared among hospitals, clinics, and tightly related systems.

    Interoperability and data-exchange are critical for the survival of government information management programs. E-government initiatives are transforming the way the government interacts with the public. More information is to be made available through web-enabled technologies. Programs such as the NASA's Scientific and Technical Information (STI) Program Office are tasked to find more effective ways to disseminate information to the public. The NASA STI Program is an agency-wide program charged with gathering, organizing, storing, and disseminating NASA-produced information for research and public use. The program is investigating the use of a new protocol called the Open Archives Initiative (OAI) as a means to improve data interoperability and data collection. OAI promotes the use of the OAI harvesting protocol as a simple way for data sharing among repositories. In two separate initiatives, the STI Program is implementing OAI In collaboration with the Air Force, Department of Energy, and Old Dominion University, the NASA STI Program has funded research on implementing the OAI to exchange data between the three organizations. The second initiative is the deployment of OAI for the NASA technical report server (TRS) environment. The NASA TRS environment is comprised of distributed technical report servers with a centralized search interface. This paper focuses on the implementation of OAI to promote interoperability among diverse data repositories.

    Full Text Available Abstract Background Concerns about the confidentiality of personal health information have been identified as a potential obstacle to implementation of Health Information Exchanges (HIEs. Considering the stigma and confidentiality issues historically associated with human immunodeficiency virus (HIV disease, we examine how trust—in technology, processes, and people—influenced the acceptability of data sharing among stakeholders prior to implementation of six HIEs intended to improve HIV care in parts of the United States. Our analyses identify the kinds of concerns expressed by stakeholders about electronic data sharing and focus on the factors that ultimately facilitated acceptability of the new exchanges. Methods We conducted 549 surveys with patients and 66 semi-structured interviews with providers and other stakeholders prior to implementation of the HIEs to assess concerns about confidentiality in the electronic sharing of patient data. The patient quantitative data were analyzed using SAS 9.2 to yield sample descriptive statistics. The analysis of the qualitative interviews with providers and other stakeholders followed an open-coding process, and convergent and divergent perspectives emerging from those data were examined within and across the HIEs. Results We found widespread acceptability for electronic sharing of HIV-related patient data through HIEs. This acceptability appeared to be driven by growing comfort with information technologies, confidence in the security protocols utilized to protect data, trust in the providers and institutions who use the technologies, belief in the benefits to the patients, and awareness that electronic exchange represents an enhancement of data sharing already taking place by other means. HIE acceptability depended both on preexisting trust among patients, providers, and institutions and on building consensus and trust in the HIEs as part of preparation for implementation.

    prior to the HDX-MS experiment. However, when studying protein complexes of more than two proteins, immobilization can possibly introduce steric limitations to the interactions. Here, we present a method based on the high affinity biotin-streptavidin interaction that allows selective capture...... of biotinylated proteins even under the extreme conditions for hydrogen/deuterium exchange quenching i.e. pH 2.5 and 0 °C. This biotin-streptavidin capture strategy allows hydrogen/deuterium exchange to occur in proteins in solution and enables characterization of specific proteins in heteromultimeric protein...... complexes without interference of peptides originating from other interaction partners in the complex. The biotin-streptavidin strategy has been successfully implemented in a model system with two recombinant monoclonal antibodies that target nonoverlapping epitopes on the human epidermal growth factor...

    As the U. S. Department of Energy (DOE) and DOE contractors have increased the magnitude and scope of their cooperative activities with other nations in the nuclear fuel cycle and waste management field, a need has developed for ready sources of information concerning foreign waste management programs, DOE technology exchange policies, bilateral fuel cycle and waste management agreements and plans and activities to implement those agreements. The INFX (International InLormation E~change) Guide is one of a series of documents that have been prepared to provide that information. The INFX Guide has been compiled under the charter of PNL's International Support Office (IPSO) to maintain for DOE a center to collect, organize, evaluate and disseminate information on foreign and international radioactive waste management programs. Because the information in this document is constantly subject to change, the document is assembled in loose-leaf form to accommodate frequent updates.

    Health Information Exchange (HIE) efforts face challenges with data quality and performance, and this becomes especially problematic when data is leveraged for uses beyond primary clinical use. We describe a secondary data infrastructure focusing on patient-encounter, nonclinical data that was built on top of a functioning HIE platform to support novel secondary data uses and prevent potentially negative impacts these uses might have otherwise had on HIE system performance. HIE efforts have generally formed for the primary clinical use of individual clinical providers searching for data on individual patients under their care, but many secondary uses have been proposed and are being piloted to support care management, quality improvement, and public health. This infrastructure review describes a module built into the Healthix HIE. Healthix, based in the New York metropolitan region, comprises 107 participating organizations with 29,946 acute-care beds in 383 facilities, and includes more than 9.2 million unique patients. The primary infrastructure is based on the InterSystems proprietary Caché data model distributed across servers in multiple locations, and uses a master patient index to link individual patients' records across multiple sites. We built a parallel platform, the "visit data warehouse," of patient encounter data (demographics, date, time, and type of visit) using a relational database model to allow accessibility using standard database tools and flexibility for developing secondary data use cases. These four secondary use cases include the following: (1) tracking encounter-based metrics in a newly established geriatric emergency department (ED), (2) creating a dashboard to provide a visual display as well as a tabular output of near-real-time de-identified encounter data from the data warehouse, (3) tracking frequent ED users as part of a regional-approach to case management intervention, and (4) improving an existing quality improvement program

  6. Interoperability and models for exchange of data between information systems in public administration

    2016-12-01

    The types of software applications used by public administrations can be divided in three main groups: document management systems, record management systems and business process systems. Each one of them generates outputs that can be used as input data to the others. This is the main reason that requires exchange of data between these three groups and well defined models that should be followed. There are also many other reasons that will be discussed in the paper. Interoperability is a key aspect when those models are implemented, especially when there are different manufactures of systems in the area of software applications used by public authorities. The report includes examples of implementation of models for exchange of data between software systems deployed in one of the biggest administration in Bulgaria.

  7. A CRIS in the Desert: The Implementation of Pure at KAUST: A Case Study in Information Exchange

    KAUST Repository

    Grenz, Daryl M.

    2016-06-10

    The integration of research information systems with existing university processes has tended towards information exchange models in which the CRIS ingests information from existing systems and takes on functions that were previously distributed across several independent solutions. This paper draws upon the experience of the implementation of a CRIS at the King Abdullah University of Science and Technology (KAUST) to posit a model in which functions remain distributed so as to take advantage of the strengths of each system. The functions discussed include institutional reporting, publications tracking, preservation of research outputs, provision of public access, researcher identity and profiling, and metrics analysis. The systems reviewed include a CRIS (Pure), a locally developed publications tracking system, a hosted DSpace repository, a locally developed ORCID integration, and a metrics dashboard (PlumX). The interactions between these systems forms a network of services to our research community, with each node connected to several others, and we discuss how we arrived at the current arrangement, as well as its drawbacks and advantages. The still limited use of standard data exchange formats like CERIF XML is discussed as a constraint that increases the costs of adding to and maintaining the network of services. At the same time we look at how increased standardization should make this distributed approach sustainable, allowing institutions like ours to mix and match complementary systems to achieve an optimal set of research information services for our needs.

    This paper investigates the application of the enterprise information system (EIS) paradigm to standardized cardiovascular condition monitoring. There are many specifications in cardiology, particularly in the ECG standardization arena. The existence of ECG formats, however, does not guarantee the implementation of homogeneous, standardized solutions for ECG management. In fact, hospital management services need to cope with various ECG formats and, moreover, several different visualization applications. This heterogeneity hampers the normalization of integrated, standardized healthcare information systems, hence the need for finding an appropriate combination of ECG formats and a suitable EIS-based software architecture that enables standardized exchange and homogeneous management of ECG formats. Determining such a combination is one objective of this paper. The second aim is to design and develop the integrated healthcare information system that satisfies the requirements posed by the previous determination. The ECG formats selected include ISO/IEEE11073, Standard Communications Protocol for Computer-Assisted Electrocardiography, and an ECG ontology. The EIS-enabling techniques and technologies selected include web services, simple object access protocol, extensible markup language, or business process execution language. Such a selection ensures the standardized exchange of ECGs within, or across, healthcare information systems while providing modularity and accessibility.

    Full Text Available Explaining and the determinants of dividend policy is one of the biggest challenges that have long been the center of attention of accounting and financial researcher and theoreticians. There are many evidences that confirm the effects of dividend and there are a lot of other potential factors whose effects on the dividend policy have not been studied yet. In this study, the effects of four variables including asymmetric information, growth opportunities, cash holding and firm size in payout dividend policy are investigated, simultaneously. The study uses the information of 140 companies listed on Tehran Stock Exchange over the period 2005-2010. In this study, 4 hypotheses are proposed and investigated. There are positive and significant relationships between asymmetric information, growth opportunities, cash holding and company size on one side and payout dividend policy on the other side.

    The Meaningful Use criteria promises to make health information exchange (HIE) much more widespread. However, the usage of the information systems made available by existing HIE efforts tends to be very low. This study sought to examine the factors associated with usage of an operational HIE system during ambulatory care visits to safety-net clinics. Overall the HIE system was accessed for 21% of encounters. However, system access took on two distinct forms. In general, usage was more likely for patients with recent emergency department visits and chronic conditions. This study indicates the organizational commitment to engage in HIE does not necessarily mean that the information systems will be always used. In addition, system usage will take on various forms for different reasons. These results reveal considerations for the development, operation and evaluation of HIE efforts.

    Safety and reliability of transgene integration in human genome continue to pose challenges for stem cell-based gene therapy. Here, we report a baculovirus-transcription activator-like effector nuclease system for AAVS1 locus-directed homologous recombination in human induced pluripotent stem cells (iPSCs). This viral system, when optimized in human U87 cells, provided a targeted integration efficiency of 95.21% in incorporating a Neo-eGFP cassette and was able to mediate integration of DNA insert up to 13.5 kb. In iPSCs, targeted integration with persistent transgene expression was achieved without compromising genomic stability. The modified iPSCs continued to express stem cell pluripotency markers and maintained the ability to differentiate into three germ lineages in derived embryoid bodies. Using a baculovirus-Cre/LoxP system in the iPSCs, the Neo-eGFP cassette at the AAVS1 locus could be replaced by a Hygro-mCherry cassette, demonstrating the feasibility of cassette exchange. Moreover, as assessed by measuring γ-H2AX expression levels, genome toxicity associated with chromosomal double-strand breaks was not detectable after transduction with moderate doses of baculoviral vectors expressing transcription activator-like effector nucleases. Given high targeted integration efficiency, flexibility in transgene exchange and low genome toxicity, our baculoviral transduction-based approach offers great potential and attractive option for precise genetic manipulation in human pluripotent stem cells.

    2017-05-05

    Health information exchange is the electronic accessibility and transferability of patient medical records across various healthcare settings and providers. In some states, patients have to formally give consent to allow their medical records to be electronically shared. The purpose of this study was to apply a novel user-centered, multistep, multiframework approach to design and test an electronic consent user interface, so patients with HIV can make more informed decisions about electronically sharing their health information. This study consisted of two steps. Step 1 was a cross-sectional, descriptive, qualitative study that used user-centric design interviews to create the user interface. This informed Step 2. Step 2 consisted of a one group posttest to examine perceptions of usefulness, ease of use, preference, and comprehension of a health information exchange electronic consent user interface. More than half of the study population had college experience, but challenges remained with overall comprehension regarding consent. The user interface was not independently successful, suggesting that in addition to an electronic consent user interface, human interaction may also be necessary to address the complexities associated with consenting to electronically share medical records. Comprehension is key factor in the ability to make informed decisions.

    Assessment is a core function of public health. Comprehensive clinical data may enhance community health assessment by providing up-to-date, representative data for use in public health programs and policies, especially when combined with community-level data relevant to social determinants. In this study we examine routinely collected and geospatially-enhanced EHR data to assess population health at various levels of geographic granularity available from a regional health information exchange. We present preliminary findings and discuss important biases in EHR data. Future work is needed to develop methods for correcting for those biases to support routine epidemiology work of public health.

    Full Text Available The main purpose of this study is to investigate the impacts of firms’ internal information environment on tax avoidance. The research method includes a data panel and is generally of semi-experimental fashion. The population of research is consisted of the entire companies and firms listed in Tehran’s stock exchange as 496 firms from the beginning of 2007 until the end of financial year of 2014. Among the population, a number of 86 firms were selected as the sample through systematic omitting method. For the purpose of data analysis, the tests of T and multivariate linear regression were incorporated into the study. Results indicate that impact of quality of internal information on tax avoidance is higher in those companies in which information play a more important role. Firms which operate under geographic dispersion make more use of the quality of their internal information, because this information helps them towards reduced tax avoidance. High quality of internal information and commercial dispersion force these firms towards avoiding larger taxes. In addition, quality of internal information is not effective on firms which are under reconstruction status.

    Full Text Available This study investigates the effect of stock liquidity and stock liquidity risk on information asymmetry in Tehran Stock Exchange (TSE listed companies. In this study, the bid-ask spread is considered as the criterion of information asymmetry. In addition, stock trade volume and the number of stock trades are considered as the criteria of stock liquidity. Some variables such as size, stock price, beta and growth are also considered as control variables. To test the hypotheses of the survey, 202 TSE listed companies over the period 2007-2012 are considered based on the multiple regression (Panel method. The evidence shows that both proposed criteria, stock liquidity criterion as well as the stock trade volume and the number of stock trades, had negative effects on information asymmetry, but this effect is not statistically meaningful. In addition, evidence shows that stock liquidity risk had positive effect on information asymmetry, which is statistically meaningful. Research results also show that firm size and beta had positive and meaningful effects on information asymmetry. Finally, the results show that growth and stock price had negative meaningful effects on information asymmetry.

    Lipid transfer proteins, such as molecules of the saposin family, facilitate extraction of lipids from biological membranes for their loading onto CD1d molecules. Although it has been shown that prosaposin-deficient mice fail to positively select invariant natural killer T (iNKT) cells, it remains unclear whether saposins can facilitate loading of endogenous iNKT cell agonists in the periphery during inflammatory responses. In addition, it is unclear whether saposins, in addition to loading, also promote dissociation of lipids bound to CD1d molecules. To address these questions, we used a combination of cellular assays and demonstrated that saposins influence CD1d-restricted presentation to human iNKT cells not only of exogenous lipids but also of endogenous ligands, such as the self-glycosphingolipid β-glucopyranosylceramide, up-regulated by antigen-presenting cells following bacterial infection. Furthermore, we demonstrated that in human myeloid cells CD1d-loading of endogenous lipids after bacterial infection, but not at steady state, requires trafficking of CD1d molecules through an endo-lysosomal compartment. Finally, using BIAcore assays we demonstrated that lipid-loaded saposin B increases the off-rate of lipids bound to CD1d molecules, providing important insights into the mechanisms by which it acts as a “lipid editor,” capable of fine-tuning loading and unloading of CD1d molecules. These results have important implications in understanding how to optimize lipid-loading onto antigen-presenting cells, to better harness iNKT cells central role at the interface between innate and adaptive immunity.

In New York, three regional health information organizations (RHIOs) implemented an HIE use case for public health reporting by demonstrating capability to deliver accurate responses to electronic queries via a set of services called the Universal Public Health Node. We investigated process and outcomes of the implementation with a comparative case study. Qualitative analysis was structured around a decision and risk matrix. Although each RHIO had a unique operational model, two common factors influenced risk management and implementation success: leadership capable of agile decision-making and commitment to a strong organizational vision. While all three RHIOs achieved certification for the public health reporting, only one has elected to deploy a production version.

    The Na/H exchanger regulatory factors, NHERF1 and NHERF2, are adapter proteins involved in targeting and assembly of protein complexes. The parathyroid hormone receptor (PTHR) interacts with both NHERF1 and NHERF2. The NHERF proteins toggle PTHR signaling from predominantly activation of adenylyl cyclase in the absence of NHERF to principally stimulation of phospholipase C when the NHERF proteins are expressed. We hypothesized that this signaling switch occurs at the level of the G protein. We measured G protein activation by [(35)S]GTPgammaS binding and G(alpha) subtype-specific immunoprecipitation using three different cellular models of PTHR signaling. These studies revealed that PTHR interactions with NHERF1 enhance receptor-mediated stimulation of G(alpha)(q) but have no effect on stimulation of G(alpha)(i) or G(alpha)(s). In contrast, PTHR associations with NHERF2 enhance receptor-mediated stimulation of both G(alpha)(q) and G(alpha)(i) but decrease stimulation of G(alpha)(s). Consistent with these functional data, NHERF2 formed cellular complexes with both G(alpha)(q) and G(alpha)(i), whereas NHERF1 was found to interact only with G(alpha)(q). These findings demonstrate that NHERF interactions regulate PTHR signaling at the level of G proteins and that NHERF1 and NHERF2 exhibit isotype-specific effects on G protein activation.

    2011-01-01

    ONC-approved state plans for HIE were reviewed for descriptions and depictions of statewide HIE technical architecture. Review was complicated by non-standard organizational elements and technical terminology across state plans. Findings were mapped to industry standard, referenced, and defined HIE architecture descriptions and characteristics. Results are preliminary due to the initial subset of ONC-approved plans available, the rapid pace of new ONC-plan approvals, and continuing advancements in standards and technology of HIE, etc. Review of 28 state plans shows virtually all include a direct messaging component, but for participating entities at state-specific levels of granularity (RHIO, enterprise, organization/provider). About ½ of reviewed plans describe a federated architecture, and ¼ of plans utilize a single-vendor “hybrid-federated” architecture. About 1/3 of states plan to leverage new federal and open exchange technologies (DIRECT, CONNECT, etc.). Only one plan describes a centralized architecture for statewide HIE, but others combine central and federated architectural approaches. PMID:22195059

  12. Collaborative distributed sensor management and information exchange flow control for multitarget tracking using Markov decision processes

    Science.gov (United States)

    Akselrod, Dimitry; Kirubarajan, T.

    2008-04-01

    In this paper, we consider the problem of collaborative management of uninhabited aerial vehicles (UAVs) for multitarget tracking. In addition to providing a solution to the problem of controlling individual UAVs, we present a method for controlling the information flow among them. The latter provides a solution to one of the main problems in decentralized tracking, namely, distributed information transfer and fusion among the participating platforms. The problem of decentralized cooperative control considered in this paper is an optimization of the information obtained by a number of UAVs, carrying out surveillance over a region, which includes a number of confirmed and suspected moving targets with the goal to track confirmed targets and detects new targets in the area. Each UAV has to decide on the most optimal path with the objective to track as many targets as possible, maximizing the information obtained during its operation with the maximum possible accuracy at the lowest possible cost. Limited communication between UAVs and uncertainty in the information obtained by each UAV regarding the location of the ground targets are addressed in the problem formulation. In order to handle these issues, the problem is presented as an operation of a group of decision makers. Markov Decision Processes (MDPs) are incorporated into the solution. A decision mechanism for collaborative distributed data fusion provides each UAV with the required data for the fusion process while substantially reducing redundancy in the information flow in the overall system. We consider a distributed data fusion system consisting of UAVs that are decentralized, heterogenous, and potentially unreliable. Simulation results are presented on a representative multisensor-multitarget tracking problem.

    2016-09-01

    This study explores the possibility of employing the Pore Surface Diffusion Model (PSDM) to predict the arsenic breakthrough curve of a packed bed system operated under continuous flow conditions with realistic groundwater, and consequently minimize the need to conduct pilot scale tests. To provide the nano-metal (hydr)oxide hybrid ion exchange media's performance in realistic water matrices without engaging in taxing pilot scale testing, the multi-point equilibrium batch sorption tests under pseudo-equilibrium conditions were performed; arsenate breakthrough curve of short bed column (SBC) was predicted by the PSDM in the continuous flow experiments; SBC tests were conducted under the same conditions to validate the model. The overlapping Freundlich isotherms suggested that the water matrix and competing ions did not have any denoting effect on sorption capacity of the media when the matrix was changed from arsenic-only model water to real groundwater. As expected, the PSDM provided a relatively good prediction of the breakthrough profile for arsenic-only model water limited by intraparticle mass transports. In contrast, the groundwater breakthrough curve demonstrated significantly faster intraparticle mass transport suggesting to a surface diffusion process, which occurs in parallel to the pore diffusion. A simple selection of DS=1/2 DP appears to be sufficient when describing the facilitated surface diffusion of arsenate inside metal (hydr)oxide nano-enabled hybrid ion-exchange media in presence of sulfate, however, quantification of the factors determining the surface diffusion coefficient's magnitude under different treatment scenarios remained unexplored.

    As social media has become more prevalent, its influence on business, politics, and society has become significant. Due to easy access and interaction between large numbers of users, information diffuses in an epidemic style on the web. Understanding the mechanisms of information diffusion through these new publication methods is important for political and marketing purposes. Among social media, web forums, where people in online communities disseminate and receive information, provide a good environment for examining information diffusion. In this paper, we model topic diffusion in web forums using the epidemiology model, the susceptible-infected-recovered (SIR) model, frequently used in previous research to analyze both disease outbreaks and knowledge diffusion. The model was evaluated on a large longitudinal dataset from the web forum of a major retail company and from a general political discussion forum. The fitting results showed that the SIR model is a plausible model to describe the diffusion process of a topic. This research shows that epidemic models can expand their application areas to topic discussion on the web, particularly social media such as web forums.

    2013-05-01

    Full Text Available There is an increasing awareness about the paramount importance of information technology within business in the context of large businesses. However, research about the investigation of the role of information technology resources in fostering collaborative communication, network governance and relationship longevity in the small and medium enterprise sector has remained scant. The primary objective of this study was to investigate the influence of information technology on collaborative communication, network governance and relationship longevity in Zimbabwe’s SME sector. Five research hypotheses were posited and sample data from 162 small and medium enterprise suppliers were collected and used to empirically test the hypotheses. The results of this study showed that information technology resources positively influenced small and medium enterprise suppliers’ collaborative communication, network governance and consequential relationship longevity with their buyers in a significant way. Overall, the current study findings provided tentative support to the proposition that information technology resources, collaborative communication and network governance should be recognised as significant antecedents for improved relationship longevity between suppliers and their buyers in the SME setting. Therefore, managers in the small and medium enterprise sector and small and medium enterprise owners need to pay attention to both collaborative communication and network governance in order to optimise information technology resource impact on their relationship longevity with their business counterparts. Limitations and future research directions were also indicated.

  6. On the role of exchange of power and information signals in control and stability of the human-robot interaction

    Kazerooni, H.

    1991-01-01

    A human's ability to perform physical tasks is limited, not only by his intelligence, but by his physical strength. If, in an appropriate environment, a machine's mechanical power is closely integrated with a human arm's mechanical power under the control of the human intellect, the resulting system will be superior to a loosely integrated combination of a human and a fully automated robot. Therefore, we must develop a fundamental solution to the problem of 'extending' human mechanical power. The work presented here defines 'extenders' as a class of robot manipulators worn by humans to increase human mechanical strength, while the wearer's intellect remains the central control system for manipulating the extender. The human, in physical contact with the extender, exchanges power and information signals with the extender. The aim is to determine the fundamental building blocks of an intelligent controller, a controller which allows interaction between humans and a broad class of computer-controlled machines via simultaneous exchange of both power and information signals. The prevalent trend in automation has been to physically separate the human from the machine so the human must always send information signals via an intermediary device (e.g., joystick, pushbutton, light switch). Extenders, however are perfect examples of self-powered machines that are built and controlled for the optimal exchange of power and information signals with humans. The human wearing the extender is in physical contact with the machine, so power transfer is unavoidable and information signals from the human help to control the machine. Commands are transferred to the extender via the contact forces and the EMG signals between the wearer and the extender. The extender augments human motor ability without accepting any explicit commands: it accepts the EMG signals and the contact force between the person's arm and the extender, and the extender 'translates' them into a desired position.

    Evidence-based pharmacotherapy is a central aspect of optimal patient care for many chronic conditions. However, medication non-adherence frequently inhibits the attainment of optimal pharmacotherapy regimens. In this study, we designed, developed, and implemented a multifaceted clinical decision support (CDS) intervention that supports evidence-based pharmacotherapy and enhanced medication adherence through the use of a scalable, claims-driven, and service-oriented approach. The intervention includes a medication management report and a low adherence alert based on thirteen evidence-based pharmacotherapy rules for seven chronic conditions. Reports and alerts are delivered to primary care clinics and care managers that participate in a healthcare information exchange in North Carolina. The resulting system architecture may enable this CDS intervention to be widely disseminated to healthcare networks through an open-source model.

    We describe our early experience with use in emergency department settings of a standards-based medication history service integrated into a health information exchange (HIE). The service sends queries from one Exchange’s emergency department interface both to a local ambulatory care system and to the medication hub services provided by a second HIE. This second HIE in turn sends requests to SureScripts and returns histories for incorporation into the first Exchange’s clinical interface. The service caches all requests to avoid costly duplicate query charges and maintains an account of queries, registered users, charges, and results obtained. Usage may be increasing as additional retail pharmacy data become available. Early results suggest that research and development emphasis requirements will of necessity shift from obtaining prescription medication history to finding new means to ensuring effective use.

    Full Text Available Abstract Background The rate of caesarean sections is increasing worldwide, yet medical literature informing women with uncomplicated pregnancies about relative risks and benefits of elective caesarean section (CS compared with vaginal delivery (VD remains scarce. A decision board may address this gap, providing systematic evidence-based information so that patients can more fully understand their treatment options. The objective of our study was to design and pre-test a decision board to guide clinical discussions and enhance informed decision-making related to delivery approach (CS or VD in uncomplicated pregnancy. Methods Development of the decision board involved two preliminary studies to determine women's preferred mode of risk presentation and a systematic literature review for the most comprehensive presentation of medical risks at the time (VD and CS. Forty women were recruited to pre-test the tool. Eligible subjects were of childbearing age (18-40 years but were not pregnant in order to avoid raising the expectation among pregnant women that CS was a universally available birth option. Women selected their preferred delivery approach and completed the Decisional Conflict Scale to measure decisional uncertainty before and after reviewing the decision board. They also answered open-ended questions reflecting what they had learned, whether or not the information had helped them to choose between birth methods, and additional information that should be included. Descriptive statistics were used to analyse sample characteristics and women's choice of delivery approach pre/post decision board. Change in decisional conflict was measured using Wilcoxon's sign rank test for each of the three subscales. Results The majority of women reported that they had learned something new (n = 37, 92% and that the tool had helped them make a hypothetical choice between delivery approaches (n = 34, 85%.

    2016-01-01

    Full Text Available Threat information exchange is a critical part of any security system. Decisions regarding security are taken with more confidence and with more results when the whole security context is known. The fog computing paradigm enhances the use cases of the already used cloud computing systems by bringing all the needed resources to the end-users towards the edge of the network. While fog decentralizes the cloud, it is very important to correlate security events which happen in branch offices around the globe for correct and timely decisions. In this article, we propose an infrastructure based on custom locally installed OSSEC agents which communicate with a central AlienVault deployment for event correlation. The agents are based on a neural network which takes actions based on risk assessment inspired by the human immune system. All of the threat information is defined by STIX expressions and a TAXII server can share this information with foreign organizations. The proposed implementation can successfully be implemented in an IoT scenario, with added security for the “brownfiled” devices.

    Atypical amygdala development may play a key role in the emergence of social disability and other symptoms of autism (Baron-Cohen et al., 2000; Schultz, 2005). The mechanisms by which this may occur have received little attention, however, and most support from behavioral and imaging studies has been concerned with socially relevant stimuli such as faces. Given the complexity of amygdala function and its known role in many other emotional tasks, we examined whether individuals with autism would demonstrate impaired performance on several tasks that have been shown to require activation of the amygdala but that do not have any explicit social meaning. Relative to a typical comparison group matched for age and IQ, our sample of 37 adolescents and adults with autism (mean age=19.7 years) demonstrated equivalent facilitation for perception and learning of emotionally relevant stimuli. On each of four tasks, there were significant main effects of emotion condition on performance for both groups. Future research regarding atypical amygdala function and emotion processing in autism should consider whether the response to nonsocial emotion factors (including negative valence or high arousal) may be intact, despite difficulties in responding to socially relevant stimuli.

    2005-09-01

    Full Text Available The aim of this article is to show how reflexology could facilitate phenomenological interviewing by probing the lifeworld of individual participants. It presents a hybrid study of phenomenological interviewing and reflexology as a holistic method of health care. In this sense, it is an interparadigmatic study, since it rests on the interface of Western and Oriental thought. This article reports on seven cases which were included in the qualitative, empirical investigation. During the sessions, reflexological readings served as impetus for inquiry into the experiences of the participants, as congestions on reflex points and along meridians were interpreted in terms of physical organs and functions. These readings were related to corresponding emotions as accepted within the reflexology paradigm. It was, however, up to the participants to inform the researcher of events and/or circumstances that caused the emotions. Thus, nonverbal data communicated information that facilitated verbal exchange concerning the life-world of each individual participant.

    Full Text Available Abstract Background Personally controlled health records (PCHRs, a subset of personal health records (PHRs, enable a patient to assemble, maintain and manage a secure copy of his or her medical data. Indivo (formerly PING is an open source, open standards PCHR with an open application programming interface (API. Results We describe how the PCHR platform can provide standard building blocks for networked PHR applications. Indivo allows the ready integration of diverse sources of medical data under a patient's control through the use of standards-based communication protocols and APIs for connecting PCHRs to existing and future health information systems. Conclusion The strict and transparent personal control model is designed to encourage widespread participation by patients, healthcare providers and institutions, thus creating the ecosystem for development of innovative, consumer-focused healthcare applications.

    Secure verified-based three-party authentication scheme for data exchange in telecare medicine information systems enables two users only store their verifiers computed from their actual password in authentication server's database. Then the authentication server can verify the users' verifiers and help them to exchange electronic medical records or electronic health records securely and conveniently. This investigation presents an efficient and secure verified-based three-party authentication scheme for data exchange in telecare medicine information systems. The proposed scheme does not use server's public keys and includes the key confirmation without extra numbers of messages and rounds. Compared to related verified-based approaches, the proposed scheme possesses higher security, has lower computational cost and fewer transmissions, and thus is suitable for the telecare medicine information systems.

    Full Text Available To inform parenting research and aid educators seeking to deliver programs that support effective parenting, this study explored types of information and communications technology (ICT used to fulfill childrearing goals. Mothers’ (N = 1,804 reports of ICT activity frequency were examined from data collected from an online survey. Results suggest that mothers’ ICT use for parenting is less frequent than general use in adulthood. Mothers employ ICT to fulfill parenting goals within and across five domains of the parenting social ecology: (a parent development, (b parent-child relationships, (c child development, (d, family development, and (e culture and community. Several types of ICT activities may strengthen parenting in a single domain, and a single ICT activity may help fulfill multiple domains. Implications for research and for promoting and selecting ICT for effective parent learning and education design are discussed.

    Clinical information collected directly from patients is critical to the practice of medicine. Past efforts to collect this information using computers have had limited utility because these efforts required users to be facile with the computerized information collecting system. In this paper we describe the design, development, and function of a computer system that uses recent technology to overcome the limitations of previous computer-based data collection tools by adapting the human-computer interface to the native language, reading literacy, and computer skills of the user. Specifically, our system uses a numerical representation of question content, multimedia, and touch screen technology to adapt the computer interface to the native language, reading literacy, and computer literacy of the user. In addition, the system supports health literacy needs throughout the data collection session and provides contextually relevant disease-specific education to users based on their responses to the questions. The system has been successfully used in an academically affiliated family medicine clinic and in an indigent adult medicine clinic.

    Full Text Available Abstract Background Expressed sequence tag (EST analyses provide a rapid and economical means to identify candidate genes that may be involved in a particular biological process. These ESTs are useful in many Functional Genomics studies. However, the large quantity and complexity of the data generated during an EST sequencing project can make the analysis of this information a daunting task. Results In an attempt to make this task friendlier, we have developed JUICE, an open source data management system (Apache + PHP + MySQL on Linux, which enables the user to easily upload, organize, visualize and search the different types of data generated in an EST project pipeline. In contrast to other systems, the JUICE data management system allows a branched pipeline to be established, modified and expanded, during the course of an EST project. The web interfaces and tools in JUICE enable the users to visualize the information in a graphical, user-friendly manner. The user may browse or search for sequences and/or sequence information within all the branches of the pipeline. The user can search using terms associated with the sequence name, annotation or other characteristics stored in JUICE and associated with sequences or sequence groups. Groups of sequences can be created by the user, stored in a clipboard and/or downloaded for further analyses. Different user profiles restrict the access of each user depending upon their role in the project. The user may have access exclusively to visualize sequence information, access to annotate sequences and sequence information, or administrative access.

    The rate of chemical synthesis and use has outpaced the development of risk values and the resolution of risk assessment methodology questions. In addition, available risk values derived by different organizations may vary due to scientific judgments, mission of the organization, or use of more recently published data. Further, each organization derives values for a unique chemical list so it can be challenging to locate data on a given chemical. Two Internet resources are available to address these issues. First, the International Toxicity Estimates for Risk (ITER) database (www.tera.org/iter) provides chronic human health risk assessment data from a variety of organizations worldwide in a side-by-side format, explains differences in risk values derived by different organizations, and links directly to each organization's website for more detailed information. It is also the only database that includes risk information from independent parties whose risk values have undergone independent peer review. Second, the Risk Information Exchange (RiskIE) is a database of in progress chemical risk assessment work, and includes non-chemical information related to human health risk assessment, such as training modules, white papers and risk documents. RiskIE is available at http://www.allianceforrisk.org/RiskIE.htm, and will join ITER on National Library of Medicine's TOXNET (http://toxnet.nlm.nih.gov/). Together, ITER and RiskIE provide risk assessors essential tools for easily identifying and comparing available risk data, for sharing in progress assessments, and for enhancing interaction among risk assessment groups to decrease duplication of effort and to harmonize risk assessment procedures across organizations.

    Demographic development and technological progress are rapidly changing the existing health systems in Europe. As a result, increasingly more complex and heterogeneous structures are emerging, which clearly differ in each of the European member state. From a company's point of view these continuously changing frameworks are leading to an increasing non-transparency regarding the structures and processes within the healthcare systems themselves. The goal is to design a suitable solution to overcome the obstacles within the information exchange process between the individual European health systems. Theoretic-deductive analysis was used for the design of an organisational structure that enables information transparency between the individual European health systems. Incorporation of an economic perspective was implemented under consideration of the theory for the building of the new institutional economics. The operational organisation analysis proves that the matrix project organisation with a function- and project-related decision system is the theoretically optimal organisational form. The organisation model derived from the theoretical analysis offers an organisation variant that guarantees an optimal processing of tasks pertaining to European health systems. This could result in the closing of an existing supply gap in the knowledge market for health systems. The evaluation of enterprise practice and the comparison with existing departments in enterprises can be explored in further research work.

    Overhauling the individual health insurance market-including through the creation of health insurance exchanges-was a key component of the Patient Protection and Affordable Care Act's multidimensional approach to addressing the long-standing problem of the uninsured in the United States. Despite succeeding in enrolling millions of Americans, the exchanges still face several challenges, including poor consumer experience, high operational and development costs, and incomplete market penetration. In light of these challenges, analysts considered a different model for the exchanges-privately facilitated exchanges-which could address these challenges and deepen the Affordable Care Act's impact. In this model, the government retains control over sovereign exchange functions but allows the private sector to assume responsibility for more-peripheral exchange functions, such as developing and sustaining exchange websites. Although private-sector entities have already undertaken exchange-related functions on a limited basis, privately facilitated exchanges could conceivably relieve the government of its responsibility for front-end website operations and consumer decision-support functions entirely. A shift to privately facilitated exchanges could improve the consumer experience, increase enrollment, and lower costs for state and federal governments. A move to such a model requires, nonetheless, managing its risks, such as reduced consumer protection, increased consumer confusion, and the possible lack of a viable revenue base for privately facilitated exchanges, especially in less populous states. On net, the benefits are large enough and the risks sufficiently manageable to seriously consider such a shift. This paper provides background information and more detail on the analysts' assessment.

    Identification of genes or even nucleotides that are responsible for quantitative and adaptive trait variation is a difficult task due to the complex interdependence between a large number of genetic and environmental factors. The polymorphism of the mitogenome is one of the factors that can contribute to quantitative trait variation. However, the effects of the mitogenome have not been comprehensively studied, since large numbers of mitogenome sequences and recorded phenotypes are required to reach the adequate power of analysis. Current research in our group focuses on acquiring the necessary mitochondria sequence information and analysing its influence on the phenotype of a quantitative trait. To facilitate these tasks we have produced software for processing pedigrees that is optimised for maternal lineage analysis. We present MaGelLAn 1.0 (maternal genealogy lineage analyser), a suite of four Python scripts (modules) that is designed to facilitate the analysis of the impact of mitogenome polymorphism on quantitative trait variation by combining molecular and pedigree information. MaGelLAn 1.0 is primarily used to: (1) optimise the sampling strategy for molecular analyses; (2) identify and correct pedigree inconsistencies; and (3) identify maternal lineages and assign the corresponding mitogenome sequences to all individuals in the pedigree, this information being used as input to any of the standard software for quantitative genetic (association) analysis. In addition, MaGelLAn 1.0 allows computing the mitogenome (maternal) effective population sizes and probability of mitogenome (maternal) identity that are useful for conservation management of small populations. MaGelLAn is the first tool for pedigree analysis that focuses on quantitative genetic analyses of mitogenome data. It is conceived with the purpose to significantly reduce the effort in handling and preparing large pedigrees for processing the information linked to maternal lines. The software source

    Although information access control models have been developed and applied to various applications, few of the previous works have addressed the issue of managing information access in the combined context of team collaboration and workflow. To facilitate this requirement, we have enhanced the Role-Based Access Control (RBAC) model through formulating universal constraints, defining bridging entities and contributing attributes, extending access permissions to include workflow contexts, synthesizing a role-based access delegation model to target on specific objects, and developing domain ontologies as instantiations of the general model to particular applications. We have successfully applied this model to the New York State HIV Clinical Education Initiative (CEI) project to address the specific needs of information management in collaborative processes. An initial evaluation has shown this model achieved a high level of agreement with an existing system when applied to 4576 cases (kappa=0.801). Comparing to a reference standard, the sensitivity and specificity of the enhanced RBAC model were at the level of 97-100%. These results indicate that the enhanced RBAC model can be effectively used for information access management in context of team collaboration and workflow to coordinate clinical education programs. Future research is required to incrementally develop additional types of universal constraints, to further investigate how the workflow context and access delegation can be enriched to support the various needs on information access management in collaborative processes, and to examine the generalizability of the enhanced RBAC model for other applications in clinical education, biomedical research, and patient care.

    Full Text Available Abstract Background To date, there are no clinically reliable predictive markers of response to the current treatment regimens for advanced colorectal cancer. The aim of the current study was to compare and assess the power of transcriptional profiling using a generic microarray and a disease-specific transcriptome-based microarray. We also examined the biological and clinical relevance of the disease-specific transcriptome. Methods DNA microarray profiling was carried out on isogenic sensitive and 5-FU-resistant HCT116 colorectal cancer cell lines using the Affymetrix HG-U133 Plus2.0 array and the Almac Diagnostics Colorectal cancer disease specific Research tool. In addition, DNA microarray profiling was also carried out on pre-treatment metastatic colorectal cancer biopsies using the colorectal cancer disease specific Research tool. The two microarray platforms were compared based on detection of probesets and biological information. Results The results demonstrated that the disease-specific transcriptome-based microarray was able to out-perform the generic genomic-based microarray on a number of levels including detection of transcripts and pathway analysis. In addition, the disease-specific microarray contains a high percentage of antisense transcripts and further analysis demonstrated that a number of these exist in sense:antisense pairs. Comparison between cell line models and metastatic CRC patient biopsies further demonstrated that a number of the identified sense:antisense pairs were also detected in CRC patient biopsies, suggesting potential clinical relevance. Conclusions Analysis from our in vitro and clinical experiments has demonstrated that many transcripts exist in sense:antisense pairs including IGF2BP2, which may have a direct regulatory function in the context of colorectal cancer. While the functional relevance of the antisense transcripts has been established by many studies, their functional role is currently unclear

    Full Text Available Blueberry growers in Maine attend annual Cooperative Extension presentations given by university faculty members. These presentations cover topics, such as, how to prevent plant disease and monitor for insect pests. In 2012, in order to make the sessions more interactive and promote learning, clicker questions and peer discussion were incorporated into the presentations. Similar to what has been shown at the undergraduate level, after peer discussion, more blueberry growers gave correct answers to multiple-choice questions than when answering independently. Furthermore, because blueberry growers are characterized by diverse levels of education, experience in the field etc., we were able to determine whether demographic factors were associated with changes in performance after peer discussion. Taken together, our results suggest that clicker questions and peer discussion work equally well with adults from a variety of demographic backgrounds without disadvantaging a subset of the population and provide an important learning opportunity to the least formally educated members. Our results also indicate that clicker questions with peer discussion were viewed as a positive addition to university-related informal science education sessions.

    Surveillance, or the systematic monitoring of disease within a population, is a cornerstone function of public health. Despite significant investment in information technologies (IT) to improve the public's health, health care providers continue to rely on manual, spontaneous reporting processes that can result in incomplete and delayed surveillance activities. Participatory design principles advocate including real users and stakeholders when designing an information system to ensure high ecological validity of the product, incorporate relevance and context into the design, reduce misconceptions designers can make due to insufficient domain expertise, and ultimately reduce barriers to adoption of the system. This paper focuses on the collaborative and informal participatory design process used to develop enhanced, IT-enabled reporting processes that leverage available electronic health records in a health information exchange to prepopulate notifiable-conditions report forms used by public health authorities. Over nine months, public health stakeholders, technical staff, and informatics researchers were engaged in a multiphase participatory design process that included public health stakeholder focus groups, investigator-engineering team meetings, public health survey and census regarding high-priority data elements, and codesign of exploratory prototypes and final form mock-ups. A number of state-mandated report fields that are not highly used or desirable for disease investigation were eliminated, which allowed engineers to repurpose form space for desired and high-priority data elements and improve the usability of the forms. Our participatory design process ensured that IT development was driven by end user expertise and needs, resulting in significant improvements to the layout and functionality of the reporting forms. In addition to informing report form development, engaging with public health end users and stakeholders through the participatory design

    Mobilizing research evidence for daily decision-making is challenging for health system decision-makers. In a previous qualitative paper, we showed the current mix of supports that Canadian health-care organizations have in place and the ones that are perceived to be helpful to facilitate the use of research evidence in health system decision-making. Factors influencing the implementation of such supports remain poorly described in the literature. Identifying the barriers to and facilitators of different interventions is essential for implementation of effective, context-specific, supports for evidence-informed decision-making (EIDM) in health systems. The purpose of this study was to identify (a) barriers and facilitators to implementing supports for EIDM in Canadian health-care organizations, (b) views about emerging development of supports for EIDM, and (c) views about the priorities to bridge the gaps in the current mix of supports that these organizations have in place. This qualitative study was conducted in three types of health-care organizations (regional health authorities, hospitals, and primary care practices) in two Canadian provinces (Ontario and Quebec). Fifty-seven in-depth semi-structured telephone interviews were conducted with senior managers, library managers, and knowledge brokers from health-care organizations that have already undertaken strategic initiatives in knowledge translation. The interviews were taped, transcribed, and then analyzed thematically using NVivo 9 qualitative data analysis software. Limited resources (i.e., money or staff), time constraints, and negative attitudes (or resistance) toward change were the most frequently identified barriers to implementing supports for EIDM. Genuine interest from health system decision-makers, notably their willingness to invest money and resources and to create a knowledge translation culture over time in health-care organizations, was the most frequently identified facilitator to

    Three-dimensional (3D) visualization is a powerful research tool that has been used to investigate complex scientific problems in various fields. It allows researchers to explore and understand processes and features that are not directly observable and help with building of new models. It has been shown that 3D visualization creates a more engaging environment for public audiences. Interactive 3D visualization can allow individuals to explore scientific concepts on their own. We present an NSF funded project developed in collaboration with UC Davis KeckCAVES, UC Davis Tahoe Environmental Research Center, ECHO Lake Aquarium & Science Center, and Lawrence Hall of Science. The Great Lakes of the World (GLOW) project aims to build interactive 3D visualization of some of the major lakes and reservoirs of the world to enhance public awareness and increase understanding and stewardship of freshwater lake ecosystems, habitats, and earth science processes. The project includes a collection of publicly available satellite imagery and digital elevation models at various resolutions for the 20 major lakes of the world as well as the bathymetry data for the 12 lakes. It also includes the vector based 'Global Lakes and Wetlands Database (GLWD)' by the World Wildlife Foundation (WWF) and the Center for Environmental System Research University of Kassel, Germany and the CIA World DataBank II data sets to show wetlands and water reservoirs at global scale. We use a custom virtual globe (Crusta) developed at the UC Davis KeckCAVES. Crusta is designed to specifically allow for visualization and mapping of features in very high spatial resolution (learn about the lake and watershed processes as well as geologic processes (e.g. faulting, landslide, glacial, volcanic) that have shaped these lakes. With the advances in 3D imaging technology, the hardware is becoming more affordable and accessible. Affordable 3D projectors, monitors and TVs will allow schools and informal science centers

    FLYSAFE is an Integrated Project of the 6th framework of the European Commission with the aim to improve flight safety through the development of an avionics solution the Next Generation Integrated Surveillance System (NGISS), which is supported by a ground based network of Weather Information Management Systems (WIMS) and access points in the form of the Ground Weather Processor (GWP). The NGISS provides information to the flight crew on the three major external hazards for aviation: weather, air traffic and terrain. The NGISS has the capability of displaying data about all three hazards on a single display screen, facilitating rapid appreciation of the situation by the flight crew. Weather Information Management Systems (WIMS) were developed to provide the NGISS and the flight crew with weather related information on in-flight icing, thunderstorms and clear-air turbulence. These products are generated on the ground from observations and model forecasts. WIMS will supply relevant information on three different scales: global, regional and local (over airport Terminal Manoeuvring Area). The Ground Weather Processor is a client-server architecture that utilises open source components, which include a geospatial database and web feature services. The GWP stores Weather Objects generated by the WIMS. An aviation user can retrieve on-demand all Weather Objects that intersect the volume of space that is of interest to them. The Weather Objects are fused with in-situ observation data and can be used by the flight management system to propose a route to avoid the hazard. In addition they can be used to display the current hazardous weather to the Flight Crew thereby raising their awareness. Within the FLYSAFE program, around 120 hours of flight trials were performed during February 2008 and August 2008. Two aircraft were involved each with separate objectives: - to assess FLYSAFE's innovative solutions for the data-link, on-board data-fusion and data-display and data

The questionnaire consisted of 18 questions on familiarity, utilization, and beliefs about HIE. The response rate was 19% (67/358). Pharmacy practice experience of respondents ranged from 0 to 5 years (18%, n = 12) to more than 20 years (61%, n = 41). More than one-half (70%) of respondents practiced in hospital settings. Many respondents (75%) were familiar with the concept of HIE; 54% currently use some type of HIE technology. Nearly all respondents felt that data in electronic health records (EHRs) should be shared between pharmacists and other health care providers. Respondents identified improved coordination of care as the greatest potential benefit, and difficulty implementing and maintaining technology as the greatest barrier of HIE. Many respondents were familiar with HIE and in favor of sharing patient records between providers. Respondents agreed that HIE has the potential to improve coordination of care but were concerned about implementing and maintaining technology. Larger pharmacy samples should be studied to determine how the results of this study compare to pharmacy populations at state and national levels.

    The quality-of-service (QoS) criteria (measured in terms of the minimum capacity requirement in this paper) are very important to practical indoor power line communication (PLC) applications as they greatly affect the user experience. With a two-way multicarrier relay configuration, in this paper we investigate the joint terminals and relay power optimization for the indoor broadband PLC environment, where the relay node works in the amplify-and-forward (AF) mode. As the QoS-constrained power allocation problem is highly non-convex, the globally optimal solution is computationally intractable to obtain. To overcome this challenge, we propose an alternating optimization (AO) method to decompose this problem into three convex/quasi-convex sub-problems. Simulation results demonstrate the fast convergence of the proposed algorithm under practical PLC channel conditions. Compared with the conventional bidirectional direct transmission (BDT) system, the relay-assisted two-way information exchange (R2WX) scheme can meet the same QoS requirement with less total power consumption.

    Out-of-hours general practitioners (GPs) cover the community over a significant proportion of a given week, and palliative care patients are seen as a priority. Little is known about how well these GPs feel supported in their line of work and whether communication exchanges work well for the proportion of their patients who have palliative care needs. For this study, GPs who provide out-of-hours care were interviewed in order to explore factors that they identified as detrimental or beneficial for good communication between themselves, patients, relatives and other professionals, specifically to palliative care encounters. Nine GPs were interviewed using face-to-face semi-structured interviews. All nine GPs worked regular out-of-hours sessions. Data from transcripts was analysed using Interpretative Phenomenological Analysis. A predominant theme expressed by GPs related to constraints within the system provided by the local private company owned out-of-hours provider. A strong feeling of 'being alone out there' emerged, with some GPs more willing to call for help than others, and others expressing their concern at access to pharmacies and medication being very inconsistent.Out-of-hours GPs felt left alone on occasion, unable to access daytime services and not knowing who to call for advice. Information hand-over systems from in-hours to out-of-hours with regard to palliative care were felt to be inadequate. Out-of-hours doctors interviewed felt left out of the care loop; handover sheets from specialist palliative care providers were a rarity. Out-of-hours services need to be mindful of the needs of the GPs they employ, in particular relating to the palliative care they provide in this setting. Other healthcare professionals should aim to keep their local out-of-hours service informed about palliative care patients they may be called to see.

    The Federation of Earth Science Information Partners (ESIP Federation, http://www.esipfed.org) formed seven years ago and now with 77 member organizations is working to "increase the quality and value of Earth science products and services .for the benefit of the ESIP Federation's stakeholder communities." Education (both formal and informal) is a huge audience that we serve. Partnerships formed by members within the ESIP Federation have created bridges that close the gap between Earth science data collection and research and the effective use of that Earth science data to explore concepts in Earth system science by the educational community. The Earth Exploration Toolbook is one of those successful collaborations. The Earth Exploration Toolbook (EET, http://serc.carleton.edu/eet) grew out of a need of the educational community (articulated by the Digital Library for Earth System Education (DLESE) community) to have better access to Earth science data and data analysis tools and help in effectively using them with students. It is a collection of web-accessible chapters, each featuring step-by-step instructions on how to use an Earth science dataset and data analysis tool to investigate an issue or concept in Earth system science. Each chapter also provides the teacher information on the outcome of the activity, grade level, standards addressed, learning goals, time required, and ideas for exploring further. The individual ESIP Federation partners alone could not create the EET. However, the ESIP Federation facilitated the partnering of members, drawing from data providers, researchers and education tool developers, to create the EET. Interest in the EET has grown since it went live with five chapters in July 2003. There are currently seven chapters with another six soon to be released. Monthly online seminars in which over a hundred educators have participated have given very positive feedback. Post workshop surveys from our telecon-online workshops indicate that

    This advance survey on Russia has performed visiting surveys and information collection at coal related organizations inside Japan and in overseas countries on production technology levels, trends and technology exchange needs in overseas coal producing countries. The project is intended to serve for improvement in the contents of and smooth execution of the engineer exchange project in the 'coal mine technology field. It was carried out by expertise people as the site surveys and the engineer reception and exchange surveys. Because of the economic crisis that has hit Russia in 1998, unprofitable coal mines were closed one after another under the coal mine scrap and build policy under the initiative of the World Bank. This situation is giving serious impacts on coal mines in the Far East Russia and the coastal areas. However, the importance of coal as the primary energy source has not been changed at all in the Far East Russia. Thus, the areas have fallen into a situation that they must rely on a great amount of introduced and imported coals as a result of weakening in coal mines in the Far Eastern area on the other hand. This paper reports mainly the situation in which the coal industries in the coastal areas are placed, and the possibilities of technology exchange. (NEDO)

    As states move forward in establishing health information exchanges (HIEs), many are looking to New York State for guidance. New York, which got an early start in building a data exchange program, has been successful in securing private investments to supplement its public funds. It has also established a credible infrastructure, governance and policy framework for a statewide HIE network. However, significant hurdles to successful HIE implementation remain. One industry report cautions that policy, security, patient consent, lack of data standards and physician acceptance still need to be addressed.

    This study evaluated the current use of commercial-off-the-shelf Clinical Information Systems (CIS) for intensive care units (ICUs) and Anesthesia Record Keeping (ARK) for operating rooms and post-anesthesia care recovery settings at three Veterans Affairs Medical Centers (VAMCs). Clinicians and administrative staff use these applications at bedside workstations, in operating rooms, at nursing stations, in physician's rooms, and in other various settings. The intention of a CIS or an ARK system is to facilitate creation of electronic records of data, assessments, and procedures from multiple medical devices. The US Department of Veterans Affairs (VA) Office of the Chief of Nursing Informatics sought to understand usage barriers and facilitators to optimize these systems in the future. Therefore, a human factors study was carried out to observe the CIS and ARK systems in use at three VAMCs in order to identify best practices and suggested improvements to currently implemented CIS and ARK systems. We conducted a rapid ethnographic study of clinical end-users interacting with the CIS and ARK systems in the critical care and anesthesia care areas in each of three geographically distributed VAMCs. Two observers recorded interactions and/or interview responses from 88 CIS and ARK end-users. We coded and sorted into logical categories field notes from 69 shadowed participants. The team transcribed and combined data from key informant interviews with 19 additional participants with the observation data. We then integrated findings across observations into meaningful patterns and abstracted the data into themes, which translated directly to barriers to effective adoption and optimization of the CIS and ARK systems. Effective optimization of the CIS and ARK systems was impeded by: (1) integration issues with other software systems; (2) poor usability; (3) software challenges; (4) hardware challenges; (5) training concerns; (6) unclear roles and lack of coordination among

    The neural mechanism of steady-state visual evoked potentials (SSVEP) is still not clearly understood. Especially, only certain frequency stimuli can evoke SSVEP. Our previous network study reveals that 8 Hz stimulus that can evoke strong SSVEP response shows the enhanced linkage strength between frontal and visual cortex. To further probe the directed information flow between the two cortex areas for various frequency stimuli, this paper develops a causality analysis based on the inversion of double columns model using particle swarm optimization (PSO) to characterize the directed information flow between visual and frontal cortices with the intracranial rat electroencephalograph (EEG). The estimated model parameters demonstrate that the 8 Hz stimulus shows the enhanced directional information flow from visual cortex to frontal lobe facilitates SSVEP response, which may account for the strong SSVEP response for 8 Hz stimulus. Furthermore, the similar finding is replicated by data-driven causality analysis. The inversion of neural mass model proposed in this study may be helpful to provide the new causality analysis to link the physiological model and the observed datasets in neuroscience and clinical researches.

    Technical information exchange was performed with Vietnamese engineers related to coal mine technologies through the overseas workshop and the technical tour. At the same time, investigations were executed on the production technology levels and needs in Vietnam, and on possibilities of transfer of Japanese technologies. The 'Overseas workshop (Vietnam)' was held on September 28, 1999 with the 'trends and problems in coal production technologies' as the main theme. Lectures were given in the session related to coal production technologies by Vietnamese coal technology experts, each from VINACOAL and IMSAT, and by two Japanese coal technology experts. A comprehensive discussion was also executed, and items of technical information were exchanged on the coal production technologies. The number of persons actually participated in the workshop counted 58, with the proceedings presented by them distributed. The Mao Khe and Duong Huy coal mines in Quang Ninh Province were visited as the technical tour, whereas the coal mine sites were inspected and opinions were exchanged with the site engineers. Gas analysis was performed in the Mao Khe mine from the viewpoint of a gas control technology, and site investigation was carried out on lock bolts in the Duong Huy mine from the viewpoint of a roof control technology.

Design: Program implementation and subsequent survey of team members. Setting: A large multisite FHT in Toronto, Ontario. Participants: Health professionals of the FHT. Main outcome measures: Usage patterns and self-reported perceptions of the Facebook group by team members. Results: At the time of the evaluation survey, the Facebook group had 43 members (37.4% of all FHT members. Activity in the group was never high, and posts by team members who were not among the researchers were infrequent throughout the study period. The content of posts fell into two broad categories: 1 information that might be useful to various team members and 2 questions posed by team members that others might be able to answer. Of the 26 team members (22.6% who completed the evaluation survey, many reported that they never logged into the Facebook page (16 respondents, and never used it to communicate with team members outside of their own site of practice (19 respondents. Only six respondents reported no concerns with using Facebook as a professional communication tool; the most frequent concerns were regarding personal and patient privacy. Conclusion: The use of social media by health care practitioners is becoming ubiquitous. However, the issues of privacy concerns and determining how to use social media without adding to provider workload must be addressed to make it a useful tool in health care.

    Advance care planning may help patients receive treatments that better align with their goals for care. We developed a Web-based decision aid called InformedTogether to facilitate shared advance care planning between chronic obstructive pulmonary disease (COPD) patients and their doctors. Our objective was to assess the usability of the InformedTogether decision aid, including whether users could interact with the decision aid to engage in tasks required for shared decision making, whether users found the decision aid acceptable, and implications for redesign. We conducted an observational study with 15 patients and 8 doctors at two ethnically and socioeconomically diverse outpatient clinics. Data included quantitative and qualitative observations of patients and doctors using the decision aid on tablet or laptop computers and data from semistructured interviews. Patients were shown the decision aid by a researcher acting as the doctor. Pulmonary doctors were observed using the decision aid independently and asked to think aloud (ie, verbalize their thoughts). A thematic analysis was implemented to explore key issues related to decision aid usability. Although patients and doctors found InformedTogether acceptable and would recommend that doctors use the decision aid with COPD patients, many patients had difficulty understanding the icon arrays that were used to communicate estimated prognoses and could not articulate the definitions of the two treatment choices-Full Code and Do Not Resuscitate (DNR). Minor usability problems regarding content, links, layout, and consistency were also identified and corresponding recommendations were outlined. In particular, participants suggested including more information about potential changes in quality of life resulting from the alternative advance directives. Some doctor participants thought the decision aid was too long and some thought it may cause nervousness among patients due to the topic area. A decision aid for shared

    This report summarizes a meeting held on February 19, 1997, in Washington, D.C. The meeting was held primarily to exchange information among the contractors involved in the U.S. Department of Energy`s efforts to improve the safety of Soviet-designed nuclear power plants. Previous meetings have been held on December 5-6, 1995, and May 22, 1996. The meetings are sponsored by the U.S. Department of Energy and coordinated by the Pacific Northwest National Laboratory. The U.S. Department of Energy works with countries to increase the level of safety at 63 Soviet-designed nuclear reactors operating in Armenia, Bulgaria, the Czech Republic, Hungary, Lithuania, Russia, Slovakia, and Ukraine. The work is implemented largely by commercial companies and individuals who provide technologies and services to the countries with Soviet-designed nuclear power plants. Attending the meeting were 71 representatives of commercial contractors, the U.S. Department of Energy, the U.S. Department of State, national laboratories, and other federal agencies. The presentations and discussions that occurred during the exchange are summarized in this report. While this report captures the general presentation and discussion points covered at the meeting, it is not a verbatim, inclusive record. To make the report useful, information presented at the meeting has been expanded to clarify issues, respond to attendees` requests, or place discussion points in a broader programmatic context. Appendixes A through F contain the meeting agenda, list of attendees, copies of presentation visuals and handouts, the Strategy Document discussed at the meeting, and a summary of attendees` post-meeting evaluation comments. As with past information exchanges, the participants found this meeting valuable and useful. In response to the participant`s requests, a fourth information exchange will be held later in 1997.

    Policy dialogues are critical for developing responsive, effective, sustainable, evidence-informed policy. Our multidisciplinary team, including researchers, physicians and senior decision-makers, comprehensively evaluated The Winnipeg Central Intake Service, a single-entry model in Winnipeg, Manitoba, to improve patient access to hip/knee replacement surgery. We used the evaluation findings to develop five evidence-informed policy directions to help improve access to scheduled clinical services across Manitoba. Using guiding principles of public participation processes, we hosted a policy roundtable meeting to engage stakeholders and use their input to refine the policy directions. Here, we report on the use and input of a policy roundtable meeting and its role in contributing to the development of evidence-informed policy. Our evidence-informed policy directions focused on formal measurement/monitoring of quality, central intake as a preferred model for service delivery, provincial scope, transparent processes/performance indicators, and patient choice of provider. We held a policy roundtable meeting and used outcomes of facilitated discussions to refine these directions. Individuals from our team and six stakeholder groups across Manitoba participated (n = 44), including patients, family physicians, orthopaedic surgeons, surgical office assistants, Winnipeg Central Intake team, and administrators/managers. We developed evaluation forms to assess the meeting process, and collected decision-maker partners' perspectives on the value of the policy roundtable meeting and use of policy directions to improve access to scheduled clinical services after the meeting, and again 15 months later. We analyzed roundtable and evaluation data using thematic analysis to identify key themes. Four key findings emerged. First, participants supported all policy directions, with revisions and key implementation considerations identified. Second, participants felt the policy roundtable

    Novel H1N1 influenza spread rapidly around the world in spring 2009. Few places were as widely affected as the New York metropolitan area. Emergency departments (EDs) in the region experienced daily visit increases in 2 distinct temporal peaks, with means of 36.8% and 60.7% over baseline in April and May, respectively, and became, in a sense, the "canary in the coal mine" for the rest of the country as we braced ourselves for resurgent spread in the fall. Biosurveillance efforts by public health agencies can lead to earlier detection, potentially forestalling spread of outbreaks and leading to better situational awareness by frontline medical staff and public health workers as they respond to a crisis, but biosurveillance has traditionally relied on manual reporting by hospital administrators when they are least able: in the midst of a public health crisis. This article explores the use of health information exchange networks, which enable the secure flow of clinical data among otherwise unaffiliated providers across entire regions for the purposes of clinical care, as a tool for automated biosurveillance reporting. Additionally, this article uses a health information exchange to assess H1N1's effect on ED visit rates and discusses preparedness recommendations and lessons learned from the spring 2009 H1N1 experience across 11 geographically distinct EDs in New York City that participate in the health information exchange.

    The Utah Improving Care through Connectivity and Collaboration (IC3) Beacon community (2010-2013) was spearheaded by HealthInsight, a nonprofit, community-based organization. One of the main objectives of IC(3) was to improve health care provided to patients with diabetes in three Utah counties, collaborating with 21 independent smaller clinics and two large health care enterprises. This paper will focus on the use of health information technology (HIT) and practice facilitation to develop and implement new care processes to improve clinic workflow and ultimately improve patients' diabetes outcomes at 21 participating smaller, independent clinics. Early in the project, we learned that most of the 21 clinics did not have the resources needed to successfully implement quality improvement (QI) initiatives. IC(3) helped clinics effectively use data generated from their electronic health records (EHRs) to design and implement interventions to improve patients' diabetes outcomes. This close coupling of HIT, expert practice facilitation, and Learning Collaboratives was found to be especially valuable in clinics with limited resources. Through this process we learned that (1) an extensive readiness assessment improved clinic retention, (2) clinic champions were important for a successful collaboration, and (3) current EHR systems have limited functionality to assist in QI initiatives. In general, smaller, independent clinics lack knowledge and experience with QI and have limited HIT experience to improve patient care using electronic clinical data. Additionally, future projects like IC(3) Beacon will be instrumental in changing clinic culture so that QI is integrated into routine workflow. Our efforts led to significant changes in how practice staff optimized their EHRs to manage and improve diabetes care, while establishing the framework for sustainability. Some of the IC(3) Beacon practices are currently smoothly transitioning to new models of care such as Patient

    2011-01-01

    Care-givers not only work as a team, but increasingly they also participate in networks. This development represents an ethical challenge to the exchange of information and to confidentiality. To revise and update earlier advice formulated by the Ethics Committee for Mental Health Care of the Brothers of Charity in Flanders, in particular concerning the question of whether shared confidentiality can be extended from a team to a network. The Ethics Committee applied an appropriate method which combined ethical discussion and literature research. The earlier advice is no longer adequate because of certain practical and theoretical grounds. The Ethics Committee chooses to take a positive view of the developing cooperation between care-givers and networks. Consequently, the committee proposes shared confidentiality, but links this to five conditions: (1) the care-givers should participate in a clearly defined and identifiable team or network, (2) they should have a caring task in common, (3) they should be pledged to confidentiality, (4) they should consult with the patient and obtain his/her informed consent, (5) they should apply 'the filter of relevance'. Care-givers can exchange information with members of a team or network, but this should be done on the basis of conditional shared confidentiality.

    In joint tasks, adjusting to the actions of others is critical for success. For joint visual search tasks, research has shown that when search partners visually receive information about each other's gaze, they use this information to adjust to each other's actions, resulting in faster search performance. The present study used a visual, a tactile and an auditory display, respectively, to provide search partners with information about each other's gaze. Results showed that search partners performed faster when the gaze information was received via a tactile or auditory display in comparison to receiving it via a visual display or receiving no gaze information. Findings demonstrate the effectiveness of tactile and auditory displays for receiving task-relevant information in joint tasks and are applicable to circumstances in which little or no visual information is available or the visual modality is already taxed with a demanding task such as air-traffic control. Practitioner Summary: The present study demonstrates that tactile and auditory displays are effective for receiving information about actions of others in joint tasks. Findings are either applicable to circumstances in which little or no visual information is available or when the visual modality is already taxed with a demanding task.

    Full Text Available Previous experiments on physical non-contact communication within same species gave rise to test for this type of communication also across the species border, which was the aim of the present study. It was found that autotrophic unicellular organisms (Euglena viridis, separated by cuvettes, affected the proliferation rate of heterotrophic unicellular organisms (Paramecium caudatum. Further, the heterotrophic unicellular organism affected also the proliferation rate of a multicellular heterotrophic organism (Rotatoria sp. and vice versa. In the case when populations (of Euglena viridis and Paramecium caudatum were shielded against electromagnetic fields in the optical spectrum from each other, no effects were measured. The results may support the notion that the organisation of ecosystems relies also on the exchange of electromagnetic fields from their constituting biosystems.

  3. Assessing the value of cooperation and information exchange in large water resources systems by multi-agent optimization: the Zambezi river case

    Science.gov (United States)

    Giuliani, M.; Castelletti, A.

    2012-04-01

    Many large-scale water resources systems are characterized by the presence of several and conflicting interests and are often managed by many independent decision-makers, belonging to different institutions or countries, who take into account only their own objectives causing downstream externalities. In this work we explore the use of multi-agent systems theory to conduct an optimization-based analysis of different levels of cooperation and information exchange in the large water reservoir system of the Zambezi River. The four largest reservoirs in the basin (Ithezhithezhi, Kafue-Gorge, Kariba and Cahora Bassa) are mainly operated for maximizing the economic revenue from hydropower energy production with considerably negative effects on the aquatic ecosystem in the Zambezi delta. We comparatively analyse the ideal situation in which a central decision-maker optimizes a global optimum and the more realistic case where all the decision-makers act independently and non-cooperatively. We then investigate how increasing levels of information exchange can help in mitigating the conflict generated by a non-cooperative setting.

  5. Exchange of information by the introduction of the advanced measurement and control systems; Utveksling av informasjon ved innfoering av AMS

    Energy Technology Data Exchange (ETDEWEB)

    2010-05-15

    Data from the advanced measurement and control systems (in Norwegian: AMS) can provide significant new impacts to society, given that the relevant information from the systems made available to customers, utilities, power suppliers and any providers of other services. There are three types of information that is important: quality-assured data, raw data and general information. Quality assured data should be collected and sent out automatically weekly to third parties (power suppliers and independent providers of services) as soon as possible after they are assured, in a handy format. Raw data, ie current consumption (instant values), should be made available for electricity suppliers and independent third parties by sending the meter to the local receiver, or via measuring system. Raw data and functionality for control may also be useful for the network owner and / or system operator. The measurement system should be used to control if possible. Customers must be given access to raw data, either via the display, PC, TV or similar. If the system opens to control through measuring system, third parties should also be given the right to send the signal through the company's computer system. The advanced measurement and control systems can also provide the ability to send customer information, including so-called statutory information (prices, disconnection, etc.). In this context it should be considered whether it might be appropriate to offer customers the display or software to receive information. (AG)

    The Radioecology Exchange (www.radioecology-exchange.org) was created in 2011 under the EU FP7 STAR (Strategy for Allied Radioecology) network of excellence. The project aims to integrate the research efforts on radioecology of nine European organisations into a sustainable network. The web site (together with associated Twitter feeds and Facebook page) currently provides the gateway to project outputs and other on-line radiation protection and radioecological resources. In 2013, the EU FP7 COMET (Coordination and implementation of a pan-European instrument for radioecology) project commenced; it aims to strengthen research on the impact of radiation on man and the environment. COMET includes the STAR partners with the addition of one Japanese and two Ukrainian research institutes. As STAR and COMET interact closely together and with the European Radioecology Alliance (www.er-alliance.org/), the Radioecology Exchange will be modified to become an international 'hub' for information related to radioecology. Project specific information will be hosted on separate web sites www.star-radioecology.org and www.comet-radioecology.org. This paper will present an overview of the resources hosted on the Radioecology Exchange inviting other scientists to contribute. Highlighted aspects of the site include: Social media (News blog, Twitter, Facebook) - Items announcing project outputs, training courses, jobs, studentships etc. Virtual laboratory - Information which encourages integration through joint research and integrated use of data and sample materials. These pages will focus on three categories: (1) Methodological: descriptions and video clips of commonly used analytical methods and protocols and the procedures used in STAR and COMET; (2) Informative: databases made available by STAR/COMET partners together with details of sample archives held.

    2008-03-01

    This paper describes how the integration between one of the RIS-systems (Adapt) in VGR and the infobroker in the central archive is implemented. The project was presented in 2006 with the title Building an IT Healthcare Enterprise by taking the standards to the limits and sometimes beyond that. The Adapt RIS is used by the Sahlgrenska University Hospital (SU) in Gothenburg and handles 8 different radiology departments. The implementation is based on HL7 version 3 and the message exchange is based on Web Services/SOAP. The base of the RIS-system was developed in the beginning of the 1990:s by a company that no longer exists. SU has always been able to modify the system by changing the source code and we have been responsible for the system-development since late 1990s. We are using IBM Informix Dynamic Server that is running on a Solaris-based cluster with additional software from Veritas/Symantec. The communication is planned to be 2-way. Our RIS-system transfers order promises, various status updates during the workflow and finally reports with various status levels. Our system will be able to receive requests and reports from the broker. The broker in turn receives these messages from other hospitals in VGR (Vastra Gotalands Regionen). We use Axis2 to generate skeleton java-code based on WSDL- and XSD-files that defines the Web Services. Axis2 is an Open Source software that is developed as a part of the Apache project. Eclipse is a development environment for Java that we use and it is also open source. Apache Tomcat is the application server that we use to receive messages from the infobroker.

    Sinaceur, Marwan; Maddux, William W; Vasiljevic, Dimitri; Perez Nückel, Ricardo; Galinsky, Adam D

    2013-06-01

    Although previous research has shown that making the first offer leads to a distributive advantage in negotiations, the current research explored how the timing of first offers affects the creativity of negotiation agreements. We hypothesized that making the first offer later rather than earlier in the negotiation would facilitate the discovery of creative agreements that better meet the parties' underlying interests. Experiment 1 demonstrated that compared with early first offers, late first offers facilitated creative agreements that better met the parties' underlying interests. Experiments 2a and 2b controlled for the duration of the negotiation and conceptually replicated this effect. The last two studies also demonstrated that the beneficial effect of late first offers was mediated by greater information exchange. Thus, negotiators need to consider the timing of first offers to fully capitalize on the first offer advantage. Implications for our understanding of creativity, motivated information exchange, and timing in negotiations are discussed.

    This project has been performed with an intention of making visiting surveys and information collection at coal related organizations in overseas coal producing countries on production technology levels and trends. The project is intended to serve for improvement in the contents of and smooth execution of the engineer exchange project in the 'coal mine technology field. It was carried out by the site surveys. The surveys revealed that the situation of the American coal industry is expected of stable increase in the demand and supply in the future, but the coal price is on the falling trend, and therefore, the industry is compelled to further increase the intensity and enhance the productivity. The industry is strongly influenced by the amended air pollution prevention act and nature destruction problems, hence further coal mine curtailment is estimated. Under such a background, it was found that the long-wall mining process progressing toward larger scale and higher productivity, and the high-wall mining process that provides higher productivity at lower cost and has less impact on the environmental problems can continue development in mountainous areas, particularly in the Appalachian area. The high-wall mining process mines coal at exposed facings on the side of a mountain by using a continuous miner, and transports the coal using machines. (NEDO)

    Full Text Available Objective – To explore and analyze, against three theoretical frameworks of information behaviours, how people with HIV/AIDS, their friends, and their family living in rural communities find information on HIV/AIDS.Design – Qualitative, individual, in‐depth, semi‐structured interviews.Setting – Two rural regions in Ontario, Canada.Subjects – Sixteen participants; 10 people with HIV/AIDS (PHAs and 6 family members or friends.Methods – Participants were recruited through health care providers, social service agencies and through snowball sampling. Semi‐structure interviews were conducted focusing on participants’ experience with HIV/AIDS, how they find and use information on HIV/AIDS, networks for information exchange and the effect of technology on information exchange. Interviews were taped, transcribed, analyzed qualitatively using NVivo software. Results were compared to three theoretical frameworks for information behaviour: 1. purposeful information seeking (i.e., the idea that people purposefully seek information to bridge perceived knowledge gaps; 2. non‐purposeful or incidental information acquisition (i.e., the idea that people absorb information from going about daily activities; and 3. information gate keeping (i.e., the concept of private individuals who act as community links and filters for information gathering and dissemination.Main Results – Consistent with the theories:•PHAs prefer to receive information from people they have a personal relationship with, particularly their physician and especially other PHAs.•PHAs’ friends and families rely on their friends and family for information, and are particularly reliant upon the PHA in their lives.•Fear of stigma and discrimination cause some to avoid seeking information or to prefer certain sources of information, such as healthcare providers, who are bound by codes of professional conduct.•Emotional support is important in information provision and

    Full Text Available The rapid development of new technology in the health care system is often contrasted by the difficulties in implementing a new system or program in an existing setting. A valuable means for bypassing these difficulties is the direct transfer of knowledge and practical experience from successful users and developers to those interested in initiating the use of the same system. We describe a system of knowledge and information transfer - Best-Practice Seminars - that is successful in surpassing many of the obstacles in implementing and managing change in the health care sector.

  18. Ipsilateral inhibition and contralateral facilitation of simple reaction time to non-foveal visual targets from non-informative visual cues.

    Orienting to an extrafoveal light cue without foveating it induces a temporary inhibition of responses to subsequent targets presented in the same visual hemifield, as evinced from the fact that reaction time (RT) to targets ipsilateral to the cue relative to fixation is longer than RT to targets contralateral to the cue. This study has tested the hypothesis that ipsilateral RT inhibition is associated with contralateral RT facilitation by attempting to divide the difference between ipsilateral and contralateral RTs into costs and benefits. A neutral condition suited to this purpose should involve a cue that does not require a lateral orientation. Such neutral condition was provided by measuring RT to lateralized light targets following a central overhead auditory cue (experiment 1) or a foveal visual cue (experiment 2). In both experiments RT in the neutral condition was intermediate between ipsilateral and contralateral RTs, and the differences reaches significance in the second experiment. Benefits over the neutral condition measured in the contralateral condition were thus associated with costs in the ipsilateral condition. These results suggest that a reciprocal antagonism between opposite turning tendencies underlies the organization of covert orienting. They also agree with general multi-channel theories of selective attention according to which the facilitation of given channels is an obligatory accompaniment of the inhibition of other competing channels and vice versa.

  19. Trs65p, a subunit of the Ypt1p GEF TRAPPII, interacts with the Arf1p exchange factor Gea2p to facilitate COPI-mediated vesicle traffic.

    The TRAPP complexes are multimeric guanine exchange factors (GEFs) for the Rab GTPase Ypt1p. The three complexes (TRAPPI, TRAPPII, and TRAPPIII) share a core of common subunits required for GEF activity, as well as unique subunits (Trs130p, Trs120p, Trs85p, and Trs65p) that redirect the GEF from the endoplasmic reticulum-Golgi pathway to different cellular locations where TRAPP mediates distinct membrane trafficking events. Roles for three of the four unique TRAPP subunits have been described before; however, the role of the TRAPPII-specific subunit Trs65p has remained elusive. Here we demonstrate that Trs65p directly binds to the C-terminus of the Arf1p exchange factor Gea2p and provide in vivo evidence that this interaction is physiologically relevant. Gea2p and TRAPPII also bind to the yeast orthologue of the γ subunit of the COPI coat complex (Sec21p), a known Arf1p effector. These and previous findings reveal that TRAPPII is part of an Arf1p GEF-effector loop that appears to play a role in recruiting or stabilizing TRAPPII to membranes. In support of this proposal, we show that TRAPPII is more soluble in an arf1Δ mutant.

  2. A Geo-Label for Geo-Referenced Information as a Service for Data Users and a Tool for Facilitating Societal Benefits of Earth Observations

    Plag, H.-P.

    2012-04-01

    Geo-referenced information is increasingly important for many scientific and societal applications. The availability of reliable and applicable spatial data and information is fundamental for addressing pressing problems such as food, water, and energy security; disaster risk reduction; climate change; environmental quality; pandemics; economic crises and wars; population migration; and, in a general sense, sustainability. Today, more than 70% of societal activities in developed countries depend directly or indirectly on geo-referenced information. The rapid development of analysis tools, such as Geographic Information Systems and web-based tools for viewing, accessing, and analyzing of geo-referenced information, and the growing abundance of openly available Earth observations (e.g., through the Global Earth Observation System of Systems, GEOSS) likely will increase the dependency of science and society on geo-referenced information. Increasingly, the tools allow the combination of data sets from various sources. Improvements of interoperability, promoted particularly by GEOSS, will strengthen this trend and lead to more tools for the combinations of data from different sources. What is currently lacking is a service-oriented infrastructure helping to ensure that data quality and applicability are not compromised through modifications and combinations. Most geo-referenced information comes without sufficient information on quality and applicability. The Group on Earth Observations (GEO) has embarked on establishing a so-called GEO Label that would provide easy-to-understand, globally available information on aspects of quality, user rating, relevance, and fit-for-usage of the products and services accessible through GEOSS (with the responsibility for the concept development delegated to Work Plan Task ID-03). In designing a service-oriented architecture that could support a GEO Label, it is important to understand the impact of the goals for the label on the

  3. Facilitation of ß-cell K(ATP) channel sulfonylurea sensitivity by a cAMP analog selective for the cAMP-regulated guanine nucleotide exchange factor Epac.

    Clinical studies demonstrate that combined administration of sulfonylureas with exenatide can induce hypoglycemia in type 2 diabetic subjects. Whereas sulfonylureas inhibit ß-cell K(ATP) channels by binding to the sulfonylurea receptor-1 (SUR1), exenatide binds to the GLP-1 receptor, stimulates ß-cell cAMP production and activates both PKA and Epac. In this study, we hypothesized that the adverse in vivo interaction of sulfonylureas and exenatide to produce hypoglycemia might be explained by Epac-mediated facilitation of K(ATP) channel sulfonylurea sensitivity. We now report that the inhibitory action of a sulfonylurea (tolbutamide) at K(ATP) channels was facilitated by 2’-O-Me-cAMP, a selective activator of Epac. Thus, under conditions of excised patch recording, the dose-response relationship describing the inhibitory action of tolbutamide at human ß-cell or rat INS-1 cell K(ATP) channels was left-shifted in the presence of 2’-O-Me-cAMP, and this effect was abolished in INS-1 cells expressing a dominant-negative Epac2. Using an acetoxymethyl ester prodrug of an Epac-selective cAMP analog (8-pCP T-2’-O-Me-cAMP-AM), the synergistic interaction of an Epac activator and tolbutamide to depolarize INS-1 cells and to raise [Ca²(+)](i) was also measured. This effect of 8-pCP T-2’-O-Me-cAMP-AM correlated with its ability to stimulate phosphatidylinositol 4,5-bisphosphate hydrolysis that might contribute to the changes in K(ATP) channel sulfonylurea-sensitivity reported here. On the basis of such findings, we propose that the adverse interaction of sulfonylureas and exenatide to induce hypoglycemia involves at least in part, a functional interaction of these two compounds to close K(ATP) channels, to depolarize ß-cells and to promote insulin secretion.

    Informal workers often face considerable risks and vulnerabilities as a consequence of their work and employment conditions. The purpose of this study was to examine the interplay between the experience of informal work and access to health, using as an example, female beer promoters employed in the informal economy, in the Lao People's Democratic Republic. In-depth interviews were undertaken with 24 female beer promoters working in beer shops, restaurants and entertainment venues in Vientiane City. The recruitment strategy of snowball sampling was used. Interviews explored the beer promoter's experience of the organization of work, perceived healthcare needs, access to healthcare and insurance, and health seeking practices. The data was analysed thematically and subsequently using Bourdieu's concepts of habitus, capital and field. Most of the beer promoters included in the study were 18 years of age, single, had worked as beer promoters for more than one year and just over half were working to support their higher education. The beer promoters demonstrated a holistic view of health, also viewing good health as contributing to being beautiful - an important attribute in their work. Many reported that their work conditions, including the noisy environment, exposure to second-hand tobacco smoke, long hours on their feet and sexual harassment negatively affected their physical and mental health. Only four participants had any form of health insurance with access to healthcare constrained by individual characteristics, health system factors and the conditions of their informal employment. Drawing on the work of Bourdieu, the study shows how both employment and illness are linked to habitus embodied in everyday practices, access to capital and the position the female beer promoters hold in the social hierarchy in the field of employment.

  9. Bankruptcy Prediction of the Electrical Firms within Iranian Electricity Exchange: Empirical Evidence from Tehran Stock Exchange

    Full Text Available Electricity exchange is known as the trajectory of power industry restructuring which facilitates achieving a direct fair market and accomplishing the privatization. However, little knowledge about market participants and their decisions may increase the investment risk and affect the economic boom cycle. As the Iranian electricity stock has started working in 2011 and the subscription has been made, it will start its services in near future; so, it would be very helpful to inform the investors about what may happen, and how to direct their portfolio into the satisfactory corridor. One way to arrive capital investment security is to predict insolvency of a business unit. Predicting the possibility of a company’s insolvency not only can prevent losing the principle and capital interest of investing, but also facilitates the most important decision makings. This paper proposes a new model for insolvency prediction of the Iranian electrical firms within future electricity exchange via an artificial bee colony algorithm. To do so, 118 firms among the electrical and energy industrial firms listed in Tehran Stock Exchange (TSE are assumed; they are used as training data to find a suitable linear classifier. The introduced algorithm is conducted on 40 test firms and obtained results are discussed in several scenarios.

      Giving children and young people information about genetic conditions and associated risk has been shown to be important to their identity, coping and decision making. Parents, however, find talking to their children difficult, and support from health professionals is often not available to them.   To explore the role of support groups in family coping, and in assisting parents' communication about risk with children in families affected by an inherited genetic condition.   Semi-structured interviews analysed using grounded theory and informed by models focusing on aspects of family communication.   Affected and unaffected children and their parents, from families affected by one of six genetic conditions, that represent different patterns of inheritance, and variations in age of onset, life expectancy and impact on families.   Parents often sought support they did not receive elsewhere from support groups. They identified benefits, but also potential disadvantages to this involvement. These related to the specific condition and also whether groups were run solely by parents or had professional input. Support groups rarely helped directly with family communication, but attendance often stimulated family discussion, and they provided information that improved parents' confidence in discussing the condition.   Support groups should be seen only as additional to the support offered by health and social care professionals. An increased understanding of the role of support groups in assisting families with genetic conditions has been highlighted, but further work is needed to explore more fully how this may be made more sustainable and far-reaching. © 2011 Blackwell Publishing Ltd.

    Schneider, D. P.; Deser, C.; Shea, D.

    2011-12-01

    When comparing CMIP5 model output to observations, researchers will be faced with a bewildering array of choices. Considering just a few of the different products available for commonly analyzed climate variables, for reanalysis there are at least half a dozen different products, for sea ice concentrations there are NASA Team or Bootstrap versions, for sea surface temperatures there are HadISST or NOAA ERSST data, and for precipitation there are CMAP and GPCP data sets. While many data centers exist to host data, there is little centralized guidance on discovering and choosing appropriate climate data sets for the task at hand. Common strategies like googling "sea ice data" yield results that at best are substantially incomplete. Anecdotal evidence suggests that individual researchers often base their selections on non-scientific criteria-either the data are in a convenient format that the user is comfortable with, a co-worker has the data handy on her local server, or a mentor discourages or recommends the use of particular products for legacy or other non-objective reasons. Sometimes these casual recommendations are sound, but they are not accessible to the broader community or adequately captured in the peer-reviewed literature. These issues are addressed by the establishment of a web-based Informed Guide with the specific goals to (1) Evaluate and assess selected climate datasets and (2) Provide expert user guidance on the strengths and limitations of selected climate datasets. The Informed Guide is based at NCAR's Climate and Global Dynamics Division, Climate Analysis Section and is funded by NSF. The Informed Guide is an interactive website that welcomes participation from the broad scientific community and is scalable to grow as participation increases. In this presentation, we will present the website, discuss how you can participate, and address the broader issues about its role in the evaluation of CMIP5 and other climate model simulations.

    2000-01-01

    Using the Internet to facilitate business-to-business commerce promises many benefits, such as dramatic cost reductions and greater access to buyers and sellers. Yet little is known about how B2B e-commerce will evolve. The authors argue that changes in the financial services industry over the past two decades provide important clues. Exchanges, they say, are not the primary source of value in information-intensive markets; value tends to accumulate among a diverse group of specialists that focus on such tasks as packaging, standard setting, arbitrage, and information management. Because scale and liquidity are vitally important to efficient trading, today's exchanges will consolidate into a relatively small set of mega-exchanges. Originators will handle the origination and aggregation of complex transactions before sending them on to mega-exchanges for execution. E-speculators, seeking to capitalize on an abundance of market information, will tend to concentrate where relatively standardized products can be transferred easily among a large group of buyers. In many markets, a handful of independent solution providers with well-known brand names and solid reputations will thrive alongside mega-exchanges. Sell-side asset exchanges will create the networks and provide the tools to allow suppliers to trade orders among themselves, sometimes after initial transactions with customers are made on the mega-exchanges. For many companies, traditional skills in such areas as product development, manufacturing, and marketing may become relatively less important, while the ability to understand and capitalize on market dynamics may become considerably more important.

    This invention concerns a heat exchanger as used in a space heater, of the type in which hot exhaust gases transfer heat to water or the like flowing through a helical heat exchange coil. A significant improvement to the efficiency of the heat exchange occurring between the air and water is achieved by using a conduit for the water having external helical fluting such that the hot gases circulate along two paths, rather than only one. A preferred embodiment of such a heat exchanger includes a porous combustion element for producing radiant heat from a combustible gas, surrounded by a helical coil for effectively transferring the heat in the exhaust gas, flowing radially from the combustion element, to the water flowing through the coil. 4 figs.

  20. Facilitation of calcium-dependent potassium current.

    Science.gov (United States)

    Thompson, S H

    1994-12-01

    The activation of Ca-dependent K+ current, Ic, was studied in macropatches on the cell bodies of molluscan neurons. When a depolarizing voltage-clamp pulse was applied repeatedly, Ic facilitated in a manner that resembled the facilitation of synaptic transmitter release. Facilitation was characterized by an increase in Ic amplitude, a progressive increase in instantaneous outward current, and a decrease in utilization time. Experiments were done to investigate the mechanism responsible for Ic facilitation. Facilitation was reduced by microinjection of an exogenous Ca2+ buffer into the cytoplasm, indicating that facilitation is a Ca(2+)-dependent process. It was also reduced at elevated temperatures. Conversely, facilitation was greatly potentiated by blocking the Na/Ca exchange mechanism. It is concluded that the facilitation of Ca-dependent K+ current results from the accumulation of Ca2+ at the inner face of the membrane during the repeated activation of Ca2+ channels by depolarization. The Ca2+ indicator fluo-3 was used in fluorescence imaging experiments to measure changes in [Ca]i near the cell membrane during repeated depolarizing pulses and the interpretation of these results was aided by numerical simulations of Ca2+ accumulation, diffusion, and buffering in the peripheral cytoplasm. These experiments showed that the time course of Ic facilitation matches the time course of Ca2+ accumulation at the membrane. It was found that the strength of Ic facilitation varies among patches on the same neuron, suggesting that the accumulation of Ca2+ is not uniform along the inner surface of the membrane and that gradients in [Ca]i develop and are maintained during trains of depolarizing pulses. Potential mechanisms that may lead to local differences in Ca2+ accumulation and Ic facilitation are discussed.

    Hydrogen exchange (HX) monitored by mass spectrometry (MS) is a powerful analytical method for investigation of protein conformation and dynamics. HX-MS monitors isotopic exchange of hydrogen in protein backbone amides and thus serves as a sensitive method for probing protein conformation...... and dynamics along the entire protein backbone. This chapter describes the exchange of backbone amide hydrogen which is highly quenchable as it is strongly dependent on the pH and temperature. The HX rates of backbone amide hydrogen are sensitive and very useful probes of protein conformation......, as they are distributed along the polypeptide backbone and form the fundamental hydrogen-bonding networks of basic secondary structure.

    Tear exchange beneath a contact lens facilitates ongoing fluid replenishment between the ocular surface and the lens. This exchange is considerably lower during the wear of soft lenses compared with rigid lenses. As a result, the accumulation of tear film debris and metabolic by-products between the cornea and a soft contact lens increases, potentially leading to complications. Lens design innovations have been proposed, but no substantial improvement in soft lens tear exchange has been reported. Researchers have determined post-lens tear exchange using several methods, notably fluorophotometry. However, due to technological limitations, little remains known about tear hydrodynamics around the lens and, to-date, true tear exchange with contact lenses has not been shown. Further knowledge regarding tear exchange could be vital in aiding better contact lens design, with the prospect of alleviating certain adverse ocular responses. This article reviews the literature to-date on the significance, implications and measurement of tear exchange with contact lenses.
