    Pytlinski, J.T. )

    1992-01-01

    All islands in the Caribbean except Puerto Rico can be classified as developing islands. Of these islands, all except Trinidad and Tobago are oil importers. Uncertainties concerning uninterrupted oil supply and increasing oil prices causes economic, social and political instability and jeopardizes further development of these islands. The paper discusses the energy situation of the Caribbean islands and presents alternative energy options. Several alternative energy projects financed by local, federal and international organizations are presented. Present and future uses of alternative energy technologies are described in different islands. Barrier which handicap developing and implementing alternative energy sources in the Caribbean are discussed. The potential and possible applications of alternative energy technologies such as: solar-thermal energy, photovoltaics, wind energy, ocean thermal energy conversion (OTEC), ocean currents and tides energy, biomass, peat energy, municipal solid wastes, bioconversion, hydropower, geothermal energy, nuclear energy and energy conservation are discussed in detail as means to alleviate the energy situation in the Caribbean islands.

  8. Telerehabilitation Technologies: Accessibility and Usability

    PubMed Central

    Pramuka, Michael; van Roosmalen, Linda

    2009-01-01

    In the fields of telehealth and telemedicine, phone and/or video technologies are key to the successful provision of services such as remote monitoring and visits. How do these technologies affect service accessibility, effectiveness, quality, and usefulness when applied to rehabilitation services in the field of telerehabilitation? To answer this question, we provide a overview of the complex network of available technologies and discuss how they link to rehabilitation applications, services, and practices as well as to the telerehabilitation end-user. This white paper will first present the numerous professional considerations that shape the use of technology in telerehabilitation service and set it somewhat apart from telemedicine. It will then provide an overview of concepts essential to usability analysis; present a summary of various telerehabilitation technologies and their strengths and limitations, and consider how the technologies interface with end users’ clinical needs for service accessibility, effectiveness, quality, and usefulness. The paper will highlight a conceptual framework (including task analyses and usability issues) that underlies a functional match between telerehabilitation technologies, clinical applications, and end-user capabilities for telerehabilitation purposes. Finally, we will discuss pragmatic issues related to user integration of telerehabilitation technology versus traditional face-to-face approaches. PMID:25945165

    Recent events in planetary exploration have profoundly changed the way both space scientists and the public regard the solar system and our place in it. These events include the Galileo data suggesting subsurface oceans in the Jovian system, ever stronger suggestions of near-surface water on Mars, as well as the complex structure observed for the Mars polar caps. And, of course, interest in icy cometary bodies is as old as humankind. Finally, the Mars north polar cap may conceivably cover and protect an ancient ocean floor, an obvious candidate ancient or extant habitat. In short, our interest in searching for life embraced early on the search for liquid water, and that has led us to an additional appreciation for water ice as both a commonplace partner with liquid water and as an issue to be addressed in the exploration of a host of interesting sites. In general, the spectrum of specialized technology for space exploration has not yet been broadened to include the requirements brought about by exploration of icy sites. We argue that technologies for access, operations, and science in icy solar system sites must be examined and their prioritized development initiated in order to successfully plan missions to these compelling sites over the next two decades. Additional information is contained in the original extended abstract.

  10. Agriculture: access to technology limited.

    PubMed

    1997-01-01

    From country to country and even regionally, the roles of women in agriculture vary, but most of their labor is in unpaid subsistence production and their contributions tend to be underestimated, according to the results of the [UN] Secretary-General's report. Depending on circumstances, they have complementary roles with men, sharing or dividing tasks in the production of crops, care of animals, and forestry management. In sub-Saharan Africa, for example, women contribute 60-80% of labor in food production for both household consumption and sale, while in Malaysia the women account for only 35% of the agricultural labor force, and in Ireland the participation rate is only 10.4%. Although women make this important amount of labor contributions to agricultural production, "development policies tend to favor export crops to earn foreign exchange and the agricultural research tends to address the improvement of production and technologies for commercial production". This results in limited access for women to technical knowledge and innovations, including irrigation, machinery, farming techniques and extension services. This is strengthened by the fact that most of the extension services target farmers who own land and can obtain credit to invest in input and technology.

  18. Programming and Technology for Accessibility in Geoscience

    NASA Astrophysics Data System (ADS)

    Sevre, E.; Lee, S.

    2013-12-01

    Many people, students and professors alike, shy away from learning to program because it is often believed to be something scary or unattainable. However, integration of programming into geoscience education can be a valuable tool for increasing the accessibility of content for all who are interested. It is my goal to dispel these myths and convince people that: 1) Students with disabilities can use programming to increase their role in the classroom, 2) Everyone can learn to write programs to simplify daily tasks, 3) With a deep understanding of the task, anyone can write a program to do a complex task, 4) Technology can be combined with programming to create an inclusive environment for all students of geoscience, and 5) More advanced knowledge of programming and technology can lead geoscientists to create software to serve as assistive technology in the classroom. It is my goal to share my experiences using technology to enhance the classroom experience as a way of addressing the aforementioned issues. Through my experience, I have found that programming skills can be included and learned by all to enhance the content of courses without detracting from curriculum. I hope that, through this knowledge, geoscience courses can become more accessible for people with disabilities by including programming and technology to the benefit of all involved.

  19. Broadband access technology for passive optical network

    NASA Astrophysics Data System (ADS)

    Chi, Sien; Yeh, Chien-Hung; Chow, Chi-Wai

    2009-01-01

    We will introduce four related topics about fiber access network technologies for PONs. First, an upstream signal powerequalizer is proposed and designed using a FP-LD in optical line terminal applied to the TDM-PON, and a 20dB dynamic upstream power range from -5 to -25dBm having a 1.7dB maximal power variation is retrieved. The fiber-fault protection is also an important issue for PON. We investigate a simple and cost-effective TDM/WDM PON system with self-protected function. Next, using RSOA-based colorless WDM-PON is also demonstrated. We propose a costeffective CW light source into RSOA for 2.5Gb/s upstream in WDM-PON together with self-healing mechanism against fiber fault. Finally, we investigate a 4Gb/s OFDM-QAM for both upstream and downstream traffic in long-reach WDM/TDM PON system under 100km transmission without dispersion compensation. As a result, we believe that these key access technologies are emerging and useful for the next generation broadband FTTH networks.

  11. Neocolonialism and Health Care Access among Marshall Islanders in the United States.

    PubMed

    Duke, Michael R

    2017-04-13

    In the Marshall Islands, a history of extensive nuclear weapons testing and covert biomedical research, coupled with the U.S.'s ongoing military presence in the country, has severely compromised the health of the local population. Despite the U.S.'s culpability in producing ill health along with high rates of emigration from the islands to the mainland United States, the large portion of Marshallese who reside in the United States face substantial barriers to accessing health care. Drawing from ongoing field research with a Marshallese community in Arkansas, this article explores the multifaceted impediments that U.S.-based Marshall Islanders face in receiving medical treatment. Calling on an expansive and inclusive notion of neocolonialism, I argue that Marshallese structural vulnerability with regard to health and health care treatment derives from their status as neocolonial subjects and from their limited claims to health-related deservingness associated with this status.

    2014-11-01

    To develop and validate a PubMed search filter, LIt.search, that automatically retrieves Aboriginal and Torres Strait Islander health literature and to make it publicly accessible through the Lowitja Institute website. Search filter development phases included: (1) scoping of the publication characteristics of Aboriginal and Torres Start Islander literature; (2) advisory group input and review; (3) systematic identification and testing of MeSH and text word terms; (4) relevance assessment of the search filter's retrieved items; and (5) translation for use in PubMed through the web. Scoping study analyses demonstrated complexity in the nature and use of possible search terms and publication characteristics. The search filter achieved a recall rate of 84.8% in the full gold standard test set. To determine real-world performance, post-hoc assessment of items retrieved by the search filter in PubMed was undertaken with 87.2% of articles deemed as relevant. The search filter was constructed as a series of URL hyperlinks to enable one-click searching. LIt.search is a search tool that facilitates research into practice for improving outcomes in Aboriginal and Torres Strait Islander health and is publicly available on the Lowitja Institute website. WHAT IS KNOWN ABOUT THIS TOPIC?: Health professionals, researchers and decision makers can find it difficult to retrieve published literature on Aboriginal and Torres Strait Islander health easily, effectively and in a timely way. WHAT DOES THIS PAPER ADD?: This paper describes a new web-based searching tool, LIt.search, which facilitates access to the relevant literature. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Ready access to published literature on Aboriginal and Torres Strait Islander health reduces a barrier to the use of this evidence in practice. LIt.search encourages the use of this evidence to inform clinical judgement and policy and service decision-making as well as reducing the burdens associated with searching for

    SciTech Connect

    Porter, K.

    1996-09-01

    In April 1996, the Federal Regulatory Commission (PERC) approved Orders 888 and 889 and released a draft rule for public comment on capacity reservation tariffs (CRTs). Order No. 888 requires electric utilities to file transmission tariffs that would allow transmission access to third parties who want to conduct wholesale transactions, and Order No. 889 requires transmission-owning utilities to set up open access, same-time information systems (OASIS), using commercial software and Internet protocols. This paper discusses these Orders in detail, as well as some of the issues before FERC with implications for renewables, which include: transmission pricing; transmission terms and conditions; reassignment of transmission capacity; defining state and FERC jurisdiction over transmission and distribution; the pricing of ancillary services; and the adoption and implementation of independent system operators.

    2009-05-01

    The upcoming launch of the Solar Dynamic Observatory (SDO), with its EVE, AIA and HMI instruments, is expected to generate an unprecedented stream of solar data products and a significant demand for them from scientist around the world. As a result, a number of scientific institutions, distributed around the world, are planing to mirror part or the whole SDO archives using the Data Record Management System (NetDRMS) and Storage Unit Management System (SUMS) frameworks as the backbone, developed both by the SDO Joint Science Operations Center (JSOC) composed of Stanford University and Lockheed Martin. The Virtual Solar Observatory (VSO) with its light distributed design presents here a solution that attempts to mask the complexity of these systems to allow solar physics researchers to continue using the same fast and easy search and data access that they have come to expect from VSO. The system takes advantage of this geographically dispersed set of nodes and product caching based on popular user requests to provide better, faster service to the solar physics community. NetDRMS and SUMS are explained in more detail in "NetDRMS: A Shared Data Management System for SDO and VSO" by Bogart et.al.

  7. The National Aerospace Initiative (NAI): Technologies For Responsive Space Access

    NASA Technical Reports Server (NTRS)

    Culbertson, Andrew; Bhat, Biliyar N.

    2003-01-01

    The Secretary of Defense has set new goals for the Department of Defense (DOD) to transform our nation's military forces. The Director for Defense Research and Engineering (DDR&E) has responded to this challenge by defining and sponsoring a transformational initiative in Science and Technology (S&T) - the National Aerospace Initiative (NAI) - which will have a fundamental impact on our nation's military capabilities and on the aerospace industry in general. The NAI is planned as a joint effort among the tri-services, DOD agencies and National Aeronautics and Space Administration (NASA). It is comprised of three major focus areas or pillars: 1) High Speed Hypersonics (HSH), 2) Space Access (SA), and 3) Space Technology (ST). This paper addresses the Space Access pillar. The NAI-SA team has employed a unique approach to identifying critical technologies and demonstrations for satisfying both military and civilian space access capabilities needed in the future. For planning and implementation purposes the NAI-SA is divided into five technology subsystem areas: Airframe, Propulsion, Flight Subsystems, Operations and Payloads. Detailed technology roadmaps were developed under each subsystem area using a time-phased, goal oriented approach that provides critical space access capabilities in a timely manner and involves subsystem ground and flight demonstrations. This S&T plan addresses near-term (2009), mid-term (2016), and long-term (2025) goals and objectives for space access. In addition, system engineering and integration approach was used to make sure that the plan addresses the requirements of the end users. This paper describes in some detail the technologies in NAI-Space Access pillar. Some areas of emphasis are: high temperature materials, thermal protection systems, long life, lightweight, highly efficient airframes, metallic and composite cryotanks, advanced liquid rocket engines, integrated vehicle health monitoring and management, highly operable systems and

  8. Access to Space for Technology Validation Missions: A Practical Guide

    2007-01-01

    Space technology experiments and validation missions share a common dilemma with the aerospace industry in general: the high cost of access to space. Whether the experiment is a so-called university cubesat, a university measurement experiment, or a NASA New Millennium Program (NMP) technology validation mission, the access to space option can be scaled appropriately for the particular constraints. A cubesat might fly as one of a number of cubesats that negotiate a flight on an experimental vehicle. A university experiment might do the same. A NASA flight validation might partner with an Air Force experimental mission.

    The Pacific Islander (PI) community suffers disproportionately from illnesses and diseases, including diabetes, heart disease and cancer. While there are tremendous health needs within the PI community, there are few health care providers from the community that exist to help address these particular needs. Many efforts have focused on health care workforce diversity to reduce and eliminate health disparities, but few have examined the issues faced in the health care work force pipeline. Understanding educational attainment among PI young adults is pivotal in speaking to a diverse health care workforce where health disparities among Pacific Islanders (PIs) may be addressed. This paper provides an in-depth, qualitative assessment of the various environmental, structural, socio-economic, and social challenges that prevent PIs from attaining higher education; it also discusses the various needs of PI young adults as they relate to psychosocial support, retention and recruitment, and health career knowledge and access. This paper represents a local, Southern California, assessment of PI young adults regarding educational access barriers. We examine how these barriers impact efforts to address health disparities and look at opportunities for health and health-related professionals to reduce and care for the high burden of illnesses and diseases in PI communities.

  10. Does technology help doctors to access, use and share knowledge?

    PubMed

    Bullock, Alison

    2014-01-01

    Given the power and pervasiveness of technology, this paper considers whether it can help doctors to access, use and share knowledge and thus contribute to their ability to uphold the part of the Hippocratic Oath concerned with respecting 'the hard-won scientific gains of those physicians in whose steps I walk' and sharing 'such knowledge as is mine with those who are to follow'. How technology supports connections between doctors and knowledge is considered by focusing on the use of mobile technology in the workplace and Web 2.0 tools. Sfard's 'acquisition' and 'participation' models are employed to help develop an understanding of what these uses of technology mean for learning and knowledge sharing. The employment of technology is not neutral in its effects. Issues relate to knowledge ownership, information overload, quality control and interpretations attached to the use of mobile devices in the workplace. These issues raise deeper questions about the nature of knowledge and social theory and socio-material research questions about the effect of technology on workplace learning. Although the empirical and theoretical evidence presented shows how technology has clear potential to contribute both to accessing evidence and sharing knowledge, there is need for further research that applies theoretical frameworks to the analysis of the impact of technology on workplace learning. © 2013 John Wiley & Sons Ltd.

    2008-07-01

    Fiber-to-the-home (FTTH) outside plant infrastructure should be so designed and constructed as to flexibly deal with increasing subscribers and system evolution to be expected in the future, taking minimization of total cost (CAPEX and OPEX) into consideration. With this in mind, fiber access architectures are reviewed and key technologies on optical fiber and cable for supporting flexible access network are presented. Low loss over wide wavelength (low water peak) and bend-insensitive single mode fiber is a future proof solution. Enhanced separable ribbon facilitates mid-span access to individual fibers in a cable installed, improving fiber utilizing efficiency and flexibility of distribution design. It also contributes to an excellent low PMD characteristic which could be required for video RF overlay system or high capacity long reach metro-access convergence network in the future. Bend-insensitive fiber based cabling technique including field installable connector greatly improves fiber/cable handling in installation and maintenance work.

    A launch vehicle at the scale and price point which allows developers to take reasonable risks with high payoff propulsion and avionics hardware solutions does not exist today. Establishing this service provides a ride through the proverbial technology "valley of death" that lies between demonstration in laboratory and flight environments. NASA's NanoLaunch effort will provide the framework to mature both earth-to-orbit and on-orbit propulsion and avionics technologies while also providing affordable, dedicated access to low earth orbit for cubesat class payloads.

  4. Emerging energy technologies in an island environment: Hawaii. [Review

    SciTech Connect

    Shupe, J.W.; Weingart, J.M.

    1980-01-01

    Island communities have energy-supply problems that differ appreciably from those of major land masses. There is usually an absence of local fossil fuel reserves, such as oil, natural gas and coal, as well as a limited infrastructure for delivering energy. This lack of flexibility requires island communities to satisfy their energy demands with indigenous resources, plus whatever energy supply is imported by sea. In recent years, the energy needs of many island communities have been met almost entirely by seaborne petroleum. As imported oil has become increasingly more expensive and less secure, greater effort has been directed by some island communities toward the development of their local energy resources. A case study illustrates the progress made to date in one island area - Hawaii - in minimizing its near-total dependence on seaborne petroleum. However, there should be some spin-off of this experience to regional energy planning, not only to other island communities, but also to regions within developing countries that share many of these characteristics. 34 references, 6 figures, 6 tables.

  7. A field application experience of integrating hydrogen technology with wind power in a remote island location

    NASA Astrophysics Data System (ADS)

    Gazey, R.; Salman, S. K.; Aklil-D'Halluin, D. D.

    This paper aims to share the field application experience related to the development of an innovative stand-alone sustainable energy system known as the PURE project. The PURE project has been developed alongside a Knowledge Transfer Partnership (KTP) scheme, which is supported by the UK Department of Trade and Industry and executed by siGEN in collaboration with The Robert Gordon University. The system has been constructed within an industrial estate on the island of Unst in Shetland, 200 miles north of the Scottish mainland. The energy system now supplies five business properties with clean reliable power and utilises wind turbine and hydrogen technology to provide a sustainable energy source. The stored hydrogen gas generated by the system is used as an energy source for periods when electrical demand within the business properties exceeds wind turbine production. The hydrogen is also utilised as a fuel source for transportation and as a transportable energy source for mobile power generation. The paper therefore gives a detailed description of the PURE project and discusses the field experience accumulated during the development and installation of the system. It also shares a number of practical issues that had to be overcome during its integration and operation. The installation of the PURE project has resulted in a number of unexpected conclusions being identified and marks a significant step forward in the accessible deployment of this technology for community use.

    1995-01-01

    NASA Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming the first NASA installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a more concentrated focus on technology transfer to both aerospace and non-aerospace industry. Use of WWW and NCSA Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution and integration of many technology transfer and technology awareness applications. This paper describes several of these innovative applications, including the on-line presentation of the entire Technology OPportunities Showcase (TOPS), an industrial partnering showcase that exists on the Web long after the actual 3-day event ended. The NASA Technical Report Server (NTRS) provides uniform access to many logically similar, yet physically distributed NASA report servers. WWW is also the foundation of the Langley Software Server (LSS), an experimental software distribution system which will distribute LaRC-developed software. In addition to the more formal technology distribution projects, WWW has been successful in connecting people with technologies and people with other people.

  16. Rocket-Based Combined-Cycle Propulsion Technology for Access-to-Space Applications

    NASA Technical Reports Server (NTRS)

    Hueter, Uwe

    1999-01-01

    NASA's Office of Aero-Space Technology (OAST) established three major goals, referred to as, "The Three Pillars for Success". The Advanced Space Transportation Program Office (ASTP) at the NASA's Marshall Space Flight Center (MSFC) in Huntsville, Ala. focuses on future space transportation technologies under the "Access to Space" pillar. One of the main activities over the past three years has been on advancing the hydrogen fueled rocket-based combined cycle (RBCC) technologies. The RBCC effort that was completed early this year was the initial step leading to flight demonstrations of the technology for space launch vehicle propulsion. Aerojet and Boeing-Rocketdyne designed, built and ground tested their RBCC engine concepts. In addition, ASTROX, Georgia Institute of Technology, McKinney Associates, Pennsylvania State University (PSU), and University of Alabama in Huntsville conducted supporting activities. The RBCC activity included ground testing of components (e.g., injectors, thrusters, ejectors and inlets) and integrated flowpaths. Inlet testing was performed at the Lewis Research Center's 1 x 1 wind tunnel. All direct connect and free-jet engine testing were conducted at the GASL facilities on Long Island, New York. Testing spanned the Mach range from sea level static to Mach 8. Testing of the rocket-only mode, simulating the final phase of the ascent mission profile, was also performed. The originally planned work on these contracts was completed in 1999. Follow-on activities have been initiated for both hydrogen and hydrocarbon fueled RBCC concepts. Studies to better understand system level issues with the integration of RBCC propulsion with earth-to-orbit vehicles have also been conducted. This paper describes the status, progress and future plans of the RBCC activities funded by NASA/MSFC with a major focus on the benefits of utilizing air-breathing combined-cycle propulsion in access-to-space applications.

    1995-01-01

    Use of Code Division Multiple Access (CDMA) technology in terrestrial wireless systems is fairly well understood. Similarly, design and operation of Power Control in a CDMA-based system in a terrestrial environment is also well established. Terrestrial multipath characteristics, and optimum design of the CDMA receiver to deal with multipath and fading conditions are reliably established. But the satellite environment is different. When the CDMA technology is adopted to the satellite environment, other design features need to be incorporated (for example; interleaving, open-loop and closed-loop power control design, diversity characteristics) to achieve comparable level of system performance. In fact, the GLOBALSTAR LEO/MSS system has incorporated all these features. Contrary to some published reports, CDMA retains the advantages in the satellite environment that are similar to those achieved in the terrestrial environment. This document gives a description of the CDMA waveform and other design features adopted for mobile satellite applications.

    The availability of curative hepatitis C therapies has created an opportunity to improve delivery and access. Local providers, government, industry, and community groups in Prince Edward Island developed an innovative province-wide care model. Our goal was to describe the first year of program implementation. Using a community based prospective observational study design, all chronic hepatitis C referrals received from April 2015 to April 2016 were recorded in a database. Primary analysis assessed the time from referral to assessment/treatment, as well as the number of referrals, assessments, and treatment initiations. Secondary objectives included: 1) Treatment effectiveness using intention-to-treat analysis; and 2) Patient treatment experience assessed using demographics, adverse events, and medication adherence. During the study period 242 referrals were received, 123 patients were seen for intake assessments, and 93 initiated direct-acting antiviral therapy based on medical need. This is compared to 4 treatment initiations in the previous 2 years. The median time from assessment to treatment initiation was 3 weeks. Eighty-two of 84 (97.6%, 95% CI 91.7 - 99.7%) patients for whom outcome data were available achieved sustained virologic response at 12 weeks post-treatment; 1 was lost to follow-up and 1 died from an unrelated event. In the voluntary registry, 39.7% of patients reported missed treatment doses. In conclusion, results from the first 12 months of this multi-phase hepatitis C elimination strategy demonstrate improved access to treatment, and high rates of safe engagement and cure for patients living with chronic hepatitis C genotype 1 infections.

  6. Improving antivenom availability and accessibility: science, technology, and beyond.

    PubMed

    Gutiérrez, José María

    2012-09-15

    Snakebite envenomings constitute a serious and neglected public health problem. Despite the fact that effective treatment exists, i.e. administration of animal-derived antivenoms, the availability and accessibility of these life-saving immunobiologicals is deficitary in various parts of the world, particularly in sub-Saharan Africa and some regions of Asia. This article discusses some of the problems that need to be circumvented in order to improve the availability and accessibility of antivenoms. The conglomerate of antivenom manufacturers is highly heterogeneous in terms of technological base, qualification of staff, implementation of Good Manufacturing Practices (GMPs), and volume of production. Therefore, improvements in antivenom quality and availability should be based on strategies tailored to the situation of each region or country; in this context, three different scenarios are discussed. Accessibility of antivenoms demands concerted efforts at multiple levels, including raising the awareness of public health authorities on the relevance of the problem, implementing innovative antivenom purchasing schemes, strengthening national distribution channels on the basis of robust epidemiological information, improving the cold chain and the provision of health services in remote rural settings, supporting the correct use of antivenoms, and promoting the involvement of local community organizations in various aspects of prevention and management. These tasks should be envisaged in terms of synergistic, interprogrammatic and intersectorial interventions, with the participation of many players.

  7. Open access for ALICE analysis based on virtualization technology

    NASA Astrophysics Data System (ADS)

    Buncic, P.; Gheata, M.; Schutz, Y.

    2015-12-01

    Open access is one of the important leverages for long-term data preservation for a HEP experiment. To guarantee the usability of data analysis tools beyond the experiment lifetime it is crucial that third party users from the scientific community have access to the data and associated software. The ALICE Collaboration has developed a layer of lightweight components built on top of virtualization technology to hide the complexity and details of the experiment-specific software. Users can perform basic analysis tasks within CernVM, a lightweight generic virtual machine, paired with an ALICE specific contextualization. Once the virtual machine is launched, a graphical user interface is automatically started without any additional configuration. This interface allows downloading the base ALICE analysis software and running a set of ALICE analysis modules. Currently the available tools include fully documented tutorials for ALICE analysis, such as the measurement of strange particle production or the nuclear modification factor in Pb-Pb collisions. The interface can be easily extended to include an arbitrary number of additional analysis modules. We present the current status of the tools used by ALICE through the CERN open access portal, and the plans for future extensions of this system.

  8. High-Performance Secure Database Access Technologies for HEP Grids

    SciTech Connect

    Matthew Vranicar; John Weicher

    2006-04-17

    The Large Hadron Collider (LHC) at the CERN Laboratory will become the largest scientific instrument in the world when it starts operations in 2007. Large Scale Analysis Computer Systems (computational grids) are required to extract rare signals of new physics from petabytes of LHC detector data. In addition to file-based event data, LHC data processing applications require access to large amounts of data in relational databases: detector conditions, calibrations, etc. U.S. high energy physicists demand efficient performance of grid computing applications in LHC physics research where world-wide remote participation is vital to their success. To empower physicists with data-intensive analysis capabilities a whole hyperinfrastructure of distributed databases cross-cuts a multi-tier hierarchy of computational grids. The crosscutting allows separation of concerns across both the global environment of a federation of computational grids and the local environment of a physicist’s computer used for analysis. Very few efforts are on-going in the area of database and grid integration research. Most of these are outside of the U.S. and rely on traditional approaches to secure database access via an extraneous security layer separate from the database system core, preventing efficient data transfers. Our findings are shared by the Database Access and Integration Services Working Group of the Global Grid Forum, who states that "Research and development activities relating to the Grid have generally focused on applications where data is stored in files. However, in many scientific and commercial domains, database management systems have a central role in data storage, access, organization, authorization, etc, for numerous applications.” There is a clear opportunity for a technological breakthrough, requiring innovative steps to provide high-performance secure database access technologies for grid computing. We believe that an innovative database architecture where the

    Geographical access to health care facilities is known to influence health services usage. As societies age, accessibility to health care becomes an increasingly acute public health concern. It is known that seniors tend to have lower mobility levels, and it is possible that this may negatively affect their ability to reach facilities and services. Therefore, it becomes important to examine the mobility situation of seniors vis-a-vis the spatial distribution of health care facilities, to identify areas where accessibility is low and interventions may be required. Accessibility is implemented using a cumulative opportunities measure. Instead of assuming a fixed bandwidth (i.e. a distance threshold) for measuring accessibility, in this paper the bandwidth is defined using model-based estimates of average trip length. Average trip length is an all-purpose indicator of individual mobility and geographical reach. Adoption of a spatial modelling approach allows us to tailor these estimates of travel behaviour to specific locations and person profiles. Replacing a fixed bandwidth with these estimates permits us to calculate customized location- and person-based accessibility measures that allow inter-personal as well as geographical comparisons. The case study is Montreal Island. Geo-coded travel behaviour data, specifically average trip length, and relevant traveller's attributes are obtained from the Montreal Household Travel Survey. These data are complemented with information from the Census. Health care facilities, also geo-coded, are extracted from a comprehensive business point database. Health care facilities are selected based on Standard Industrial Classification codes 8011-21 (Medical Doctors and Dentists). Model-based estimates of average trip length show that travel behaviour varies widely across space. With the exception of seniors in the downtown area, older residents of Montreal Island tend to be significantly less mobile than people of other age cohorts

    Three archaeological sites on California's Channel Islands show that Paleoindians relied heavily on marine resources. The Paleocoastal sites, dated between ~12,200 and 11,200 years ago, contain numerous stemmed projectile points and crescents associated with a variety of marine and aquatic faunal remains. At site CA-SRI-512 on Santa Rosa Island, Paleocoastal peoples used such tools to capture geese, cormorants, and other birds, along with marine mammals and finfish. At Cardwell Bluffs on San Miguel Island, Paleocoastal peoples collected local chert cobbles, worked them into bifaces and projectile points, and discarded thousands of marine shells. With bifacial technologies similar to those seen in Western Pluvial Lakes Tradition assemblages of western North America, the sites provide evidence for seafaring and island colonization by Paleoindians with a diversified maritime economy.

  11. Should HIV discordant couples have access to assisted reproductive technologies?

    PubMed Central

    Spriggs, M; Charles, T

    2003-01-01

    In this paper we identify and evaluate arguments for and against offering assisted reproductive technologies (ART), specifically IVF, to HIV discordant couples (male partner HIV positive, female partner HIV negative). The idea of offering ART to HIV discordant couples generates concerns about safety and public health and raises questions such as: what is an acceptable level of risk to offspring and should couples who want this assistance be subject to selection criteria; should they undergo scrutiny about their suitability as parents when those who are able to conceive naturally face no such scrutiny and people with other illnesses are given access to ART? We conclude that offering ART to HIV discordant couples is likely to produce more benefit than harm and violates no ethical principles. Nevertheless, a decision to deny treatment need not constitute unjustified discrimination. PMID:14662810

  12. Assisted reproductive technologies and equity of access issues.

    PubMed

    Peterson, M M

    In Australia and other countries, certain groups of women have traditionally been denied access to assisted reproductive technologies (ARTs). These typically are single heterosexual women, lesbians, poor women, and those whose ability to rear children is questioned, particularly women with certain disabilities or who are older. The arguments used to justify selection of women for ARTs are most often based on issues such as scarcity of resources, and absence of infertility (in lesbians and single women), or on social concerns: that it "goes against nature"; particular women might not make good mothers; unconventional families are not socially acceptable; or that children of older mothers might be orphaned at an early age. The social, medical, legal, and ethical reasoning that has traditionally promoted this lack of equity in access to ARTs, and whether the criteria used for client deselection are ethically appropriate in any particular case, are explored by this review. In addition, the issues of distribution and just "gatekeeping" practices associated with these sensitive medical services are examined.

    1993-01-01

    Whereas the introduction of new technologies previously has raised the ethical question of who ought to have access to a new procedure or device, genetic testing technology raises the new ethical question of to whom access to a new technology ought to be limited. In this article we discuss the implications of employers and private health insurance companies having access to genetic testing technology. Although there may be legitimate business interests in allowing employers and insurers to conduct genetic screening, there are other valid societal interests in regulating or limiting the use of this technology by third parties. Public policy developed in the area of new genetic technology must reflect such interests.

    As the world population is ageing, studies on the socio-economic and health consequences are proliferating. Little has been done on the effectiveness and impact elderly may benefit from the use of technology in their everyday life. The pilot study, implemented within a funded project aimed at identifying sustainable actions to promote Seniors' quality of life, intended to investigate this kind of interaction in terms of accessibility and acceptability that senior citizen experience with technological devices promoting motor and cognitive training. In the hypothesis, interfaces and technological artifacts, that still take in little account the seniors' physical characteristics (e.g. physiological limitations in sight, hearing, movement) and cognitive processes (selective memory often driven by practical needs), can cause elderly to mistrust technology. Study participants were twenty over seventy-year-old people, who were observed and interviewed in context in a two-hour training session regarding the technological devices user experience. The results are presented with scenario-based techniques that help represent typologies of users in different use situations. Findings confirm the hypothesis, highlighting that elderly may accept technological artifacts when they perceive them as bringing benefits in terms of well-being and health.

  2. Fragmentation approach to the point-island model with hindered aggregation: Accessing the barrier energy

    NASA Astrophysics Data System (ADS)

    2017-07-01

    We study the effect of hindered aggregation on the island formation process in a one- (1D) and two-dimensional (2D) point-island model for epitaxial growth with arbitrary critical nucleus size i . In our model, the attachment of monomers to preexisting islands is hindered by an additional attachment barrier, characterized by length la. For la=0 the islands behave as perfect sinks while for la→∞ they behave as reflecting boundaries. For intermediate values of la, the system exhibits a crossover between two different kinds of processes, diffusion-limited aggregation and attachment-limited aggregation. We calculate the growth exponents of the density of islands and monomers for the low coverage and aggregation regimes. The capture-zone (CZ) distributions are also calculated for different values of i and la. In order to obtain a good spatial description of the nucleation process, we propose a fragmentation model, which is based on an approximate description of nucleation inside of the gaps for 1D and the CZs for 2D. In both cases, the nucleation is described by using two different physically rooted probabilities, which are related with the microscopic parameters of the model (i and la). We test our analytical model with extensive numerical simulations and previously established results. The proposed model describes excellently the statistical behavior of the system for arbitrary values of la and i =1 , 2, and 3.

    Thornton, Randall J.

    2007-01-01

    The need for a high specific impulse LOX/LH2 pump-fed lunar lander engine has been established by NASA for the new Exploration architecture. Preliminary studies indicate that a 4 engine cluster in the thrust range of 9,000-lbf each is a likely configuration for the main propulsion of the manned lunar lander vehicle. The main Lunar Surface Access Module engines will likely be responsible for mid-course correction burns, lunar orbit insertion burns, a deorbit burn, and the powered descent to the lunar surface. This multi-task engine philosophy imposes a wide throttling requirement on the engines in the range of 10:1. Marshall Space Flight Center has initiated an internal effort to mature the technologies needed for full scale development of such a LOX/LH2 pump-fed engine. In particular, a fuel turbopump is being designed and fabricated at MSFC to address the issues that a small high speed turbopump of this class will face. These issues include adequate throttling performance of the pump and turbine over a very wide operating range. The small scale of the hardware presents issues including performance scaling, and manufacturing issues like that will challenge the traditional methods we have used to fabricate and assemble larger scale turbopumps. The small high speed turbopump being developed at MSFC will operate at speeds greater than 100,000-rpm. These speeds create issues that include structural dynamics and high cycle fatigue as well as rotordynamic stability. The fuel turbopump development at MSFC will address these issues, and plans are in work for component level testing as well as operation in a test bed engine environment. The fuel turbopump design is nearing completion and described herein.

    Hepworth, Julie; Askew, Deborah; Foley, Wendy; Duthie, Deb; Shuter, Patricia; Combo, Michelle; Clements, Lesley-Ann

    2015-06-06

    Aboriginal and Torres Strait Islander people experience higher levels of psychological distress and mental ill health than their non-Indigenous counterparts, but underuse mental health services. Interventions are required to address the structural and functional access barriers that cause this underuse. In 2012, the Southern Queensland Centre of Excellence in Aboriginal and Torres Strait Islander Primary Health Care employed a psychologist and a social worker to integrate mental health care into its primary health care services. This research study examines the impact of this innovation. A mixed-method research design was used whereby a series of qualitative open-ended interviews were conducted with 7 psychology clients, 5 social work clients, the practice dietician, and the social worker and psychologist. General practitioners, practice nurses, Aboriginal Health Workers and receptionists participated in 4 focus groups. Key themes were identified, discussed, refined and agreed upon by the research team. Occasions of service by the psychologist and social worker were reviewed and quantitative data presented. Clients and staff were overwhelmingly positive about the inclusion of a psychologist and a social worker as core members of a primary health care team. In one-year, the psychologist and social worker recorded 537 and 447 occasions of service respectively, and referrals to a psychologist, psychiatrist, mental health worker or counsellor increased from 17% of mental health clients in 2010 to 51% in 2012. Increased access by Aboriginal and Torres Strait Islander people to mental health care was related to three main themes: (1) Responsiveness to community needs; (2) Trusted relationships; and (3) Shared cultural background and understanding.

    Lee, Ka-Lun; Li, Jie; Chan, Chien Aun; Anthapadmanabhan, N. Prasanth; Chow, Hungkei (Keith)

    2015-12-01

    This article discusses the fundamental issues and the technologies to achieve an energy-efficient Gigabit-Ethernet point-to-point (PtP) fiber access network. To minimize the power consumption of PtP fiber access for long-term development, it is essential to optimize each of the network components such as optical transceiver, user network interface, Ethernet aggregator and also their modes of operation. Our analysis shows that the energy consumption of a PtP fiber access network using our proposed technologies can be up to 7.5 times lower than that of the 2010 technologies when a combination of appropriate technologies is applied.

  15. Photolytic Destruction Technology demonstration, NAS North Island, Site 9. Final contract report, October 1997--February 1998

    SciTech Connect

    1998-08-01

    The Photolytic Destruction Technology was chosen for demonstration, as part of the Navy Environmental Leadership Program (NELP), at Naval Air Station (NAS) North Island`s Site 9 soil vapor extraction (SVE) system. The demonstration was conducted, under contract N47408-97-C-0215 through Naval Facilities Engineering Service Center`s Broad Agency Announcement (BAA) program, to Process Technologies Incorporated (PTI), beginning October 7, 1997 and ending February 12, 1998, for 128 days. The literature search, demonstration oversight, and evaluation were funded by the Pollution Abatement Ashore Program managed by Naval Facilities Engineering Command and sponsored by the Environmental Protection, Safety and Occupational Health Division (N45) of the Chief of Naval Operations. The system was installed to treat a slip stream containing volatile organic compounds (VOCs) from the operating SVE system already installed at the site. The goal of this demonstration was to obtain the necessary cost and performance data, including the lessons learned, on the system comprising of a concentrator, condenser, and photolytic destruction unit (PDU), for comparison with other treatment technologies. The system was demonstrated on air stream contaminated with halogenated and non-halogenated VOCs such as l,2- dichloroethene, trichloroethene, tetrachloroethene, toluene, and octane. The test results indicated that the system was effective in removing VOCs in thc SVE off-gas to below the maximum allowable emissions of 25 parts per million by volume. The average total DRE achieved for VOCs was 95.44% whereas the PDU alone demonstrated an overall DRE of 97%. The estimated unit cost to treat SVE off-gas at NAS North Island`s Site 9, for a 3,000 standard cubic feet per minute PTI system, is $3.77 per pound of VOC treated.

  20. Emerging technologies and web accessibility: research challenges and opportunities focussing on vision issues.

    PubMed

    Harper, Simon; Yesilada, Yeliz

    2012-01-01

    This is a technological review paper focussed on identifying both the research challenges and opportunities for further investigation arising from emerging technologies, and it does not aim to propose any recommendation or standard. It is focussed on blind and partially sighted World Wide Web (Web) users along with others who use assistive technologies. The Web is a fast moving interdisciplinary domain in which new technologies, techniques and research is in perpetual development. It is often difficult to maintain a holistic view of new developments within the multiple domains which together make up the Web. This suggests that knowledge of the current developments and predictions of future developments are additionally important for the accessibility community. Web accessibility has previously been characterised by the correction of our past mistakes to make the current Web fulfil the original vision of access for all. New technologies were not designed with accessibility in mind and technologies that could be useful for addressing accessibility issues were not identified or adopted by the accessibility community. We wish to enable the research community to undertake preventative measures and proactively address challenges, while recognising opportunities, before they become unpreventable or require retrospective technological enhancement. This article then reviews emerging trends within the Web and Web Accessibility domains.

  7. Access from Space: A New Perspective on NASA's Space Transportation Technology Requirements and Opportunities

    Rasky, Daniel J.

    2004-01-01

    The need for robust and reliable access from space is clearly demonstrated by the recent loss of the Space Shuttle Columbia; as well as the NASA s goals to get the Shuttle re-flying and extend its life, build new vehicles for space access, produce successful robotic landers and s a q k retrr? llisrions, and maximize the science content of ambitious outer planets missions that contain nuclear reactors which must be safe for re-entry after possible launch aborts. The technology lynch pin of access from space is hypersonic entry systems such the thermal protection system, along with navigation, guidance and control (NG&C). But it also extends to descent and landing systems such as parachutes, airbags and their control systems. Current space access technology maturation programs such as NASA s Next Generation Launch Technology (NGLT) program or the In-Space Propulsion (ISP) program focus on maturing laboratory demonstrated technologies for potential adoption by specific mission applications. A key requirement for these programs success is a suitable queue of innovative technologies and advanced concepts to mature, including mission concepts enabled by innovative, cross cutting technology advancements. When considering space access, propulsion often dominates the capability requirements, as well as the attention and resources. From the perspective of access from space some new cross cutting technology drivers come into view, along with some new capability opportunities. These include new miniature vehicles (micro, nano, and picosats), advanced automated systems (providing autonomous on-orbit inspection or landing site selection), and transformable aeroshells (to maximize capabilities and minimize weight). This paper provides an assessment of the technology drivers needed to meet future access from space mission requirements, along with the mission capabilities that can be envisioned from innovative, cross cutting access from space technology developments.

    2016-02-01

    Tremendous efforts have been developed for multi-Tbps over ultra-long distance and metro and access optical networks. With the exponential increase demand on data transmission, storage and serving, especially the 5G wireless access scenarios, the optical Internet networking has evolved to data-center based optical networks pressuring on novel and economical access transmission systems. This paper reports (1) Experimental platforms and transmission techniques employing band-limited optical components operating at 10G for 100G based at 28G baud. Advanced modulation formats such as PAM-4, DMT, duo-binary etc are reported and their advantages and disadvantages are analyzed so as to achieve multi-Tbps optical transmission systems for access inter- and intra- data-centered-based networks; (2) Integrated multi-Tbps combining comb laser sources and micro-ring modulators meeting the required performance for access systems are reported. Ten-sub-carrier quantum dot com lasers are employed in association with wideband optical intensity modulators to demonstrate the feasibility of such sources and integrated micro-ring modulators acting as a combined function of demultiplexing/multiplexing and modulation, hence compactness and economy scale. Under the use of multi-level modulation and direct detection at 56 GBd an aggregate of higher than 2Tbps and even 3Tbps can be achieved by interleaved two comb lasers of 16 sub-carrier lines; (3) Finally the fundamental designs of ultra-compacts flexible filters and switching integrated components based on Si photonics for multi Tera-bps active interconnection are presented. Experimental results on multi-channels transmissions and performances of optical switching matrices and effects on that of data channels are proposed.

    2012-01-01

    In the United States, Hispanic populations tend to have higher incidences of chronic disease such as diabetes, cardiovascular disease, hypertension, obesity and hyperlipidemias [1]. They are also more likely to be underinsured or uninsured than other populations [2]. The purpose of this descriptive technology assessment survey study was to determine computer and internet access, skill level and health education information preferences of a rural Hispanic (primarily Mexican-American) population in the United States. Among the sample, 81% of individuals who answered the survey had a computer and internet access in their home. Nineteen percent did not have computers or internet access in their homes. Compared to the average 54% home internet access found by the Pew Hispanic Research Center the rural convenience sample in this study had a high percentage of technology access. Recommendations include using multimedia to improve the health information accessability among Hispanic persons.

    2016-11-01

    Women from disadvantaged socio-economic groups access assisted reproductive technology treatment less than women from more advantaged groups. However, women from disadvantaged groups tend to start families younger, making them less likely to suffer from age-related subfertility and potentially have less need for fertility treatment. Whether socio-economic disparities in access to assisted reproductive technology treatment persist after controlling for the need for treatment, has not been previously explored. This population based study demonstrates that socio-economic disparities in access to assisted reproductive technology treatment persist after adjusting for several confounding factors, including age at first birth (used as a measure of delayed childbearing, hence a proxy for need for fertility treatment), geographic remoteness and Australian jurisdiction. Assisted reproductive technology access progressively decreased as socio-economic quintiles became more disadvantaged, with a 15.8% decrease in access in the most disadvantaged quintile compared with the most advantaged quintile after controlling for confounding factors. The adjusted rate of access to assisted reproductive technology treatment also decreased by 12.3% for women living in regional and remote areas compared with those in major cities. These findings indicate that financial and sociocultural barriers to assisted reproductive technology treatment remain in disadvantaged groups after adjusting for need.

  13. Transformational Technologies to Expedite Space Access and Development

    NASA Astrophysics Data System (ADS)

    Rather, John D. G.

    2010-01-01

    Throughout history the emergence of new technologies has enabled unforeseen breakthrough capabilities that rapidly transformed the world. Some global examples from the twentieth century include AC electric power, nuclear energy, and turbojet engines. At the systems level, success of both Apollo and the Space Shuttle programs depended upon taming hydrogen propulsion and developing high-temperature atmospheric reentry materials. Human space development now is stymied because of a great need for breakthrough technologies and strategies. It is believed that new capabilities exist within the present states-of-the-art of superconducting technology that can be implemented to transform the future of human space development. This paper is an overview of three other papers presented within this forum, which summarizes the principles and consequences of StarTram, showing how the resulting breakthrough advantages can lead directly to safe space tourism and massive development of the moon, Mars and the outer solar system. StarTram can implement cost-effective solar power from space, simple utilization of asteroid material to protect humans from ionizing radiation, and effective defense of the Earth from devastating cosmic impacts. Synergistically, StarTram technologies will revolutionize ground transportation on the Earth, leading to enormous reduction in energy consumption and creation of millions of jobs. High energy lasers will also be discussed because of their importance to power beaming applications.

    Rather, John D. G.

    2010-01-28

    Throughout history the emergence of new technologies has enabled unforeseen breakthrough capabilities that rapidly transformed the world. Some global examples from the twentieth century include AC electric power, nuclear energy, and turbojet engines. At the systems level, success of both Apollo and the Space Shuttle programs depended upon taming hydrogen propulsion and developing high-temperature atmospheric reentry materials. Human space development now is stymied because of a great need for breakthrough technologies and strategies. It is believed that new capabilities exist within the present states-of-the-art of superconducting technology that can be implemented to transform the future of human space development. This paper is an overview of three other papers presented within this forum, which summarizes the principles and consequences of StarTram, showing how the resulting breakthrough advantages can lead directly to safe space tourism and massive development of the moon, Mars and the outer solar system. StarTram can implement cost-effective solar power from space, simple utilization of asteroid material to protect humans from ionizing radiation, and effective defense of the Earth from devastating cosmic impacts. Synergistically, StarTram technologies will revolutionize ground transportation on the Earth, leading to enormous reduction in energy consumption and creation of millions of jobs. High energy lasers will also be discussed because of their importance to power beaming applications.

    Objective Information technology can improve the quality, safety, and efficiency of healthcare delivery by improving provider and patient access to health information. We conducted a nonrandomized, cross-sectional, self-report survey to determine whether Alaska Native and American Indian (AN/AI) people have access to the health communication technologies available through a patient-centered medical home. Methods In 2011, we administered a self-report survey in an urban, tribally owned and operated primary care center serving AN/AI adults. Patients in the center’s waiting rooms completed the survey on paper; center staff completed it electronically. Results Approximately 98% (n = 654) of respondents reported computer access, 97% (n = 650) email access, and 94% (n = 631) mobile phone use. Among mobile phone users, 60% had Internet access through their phones. Rates of computer access (p = .011) and email use (p = .005) were higher among women than men, but we found no significant gender difference in mobile phone access to the Internet or text messaging. Respondents in the oldest age category (65–80 years of age) were significantly less likely to anticipate using the Internet to schedule appointments, refill medications, or communicate with their health care providers (all p < .001). Conclusion Information on use of health communication technologies enables administrators to deploy these technologies more efficiently to address health concerns in AN/AI communities. Our results will drive future research on health communication for chronic disease screening and health management. PMID:27169131

    This paper provides insights on the status of broadband optical access market and technologies in Europe and on the expected trends for the next generation optical access networks. The final target for most operators, cities or any other player is of course FTTH (Fibre To The Home) deployment although we can expect intermediate steps with copper or wireless technologies. Among the two candidate architectures for FTTH, PON (Passive Optical Network) is by far the most attractive and cost effective solution. We also demonstrate that Ethernet based optical access network is very adequate to all-IP networks without any incidence on the level of quality of service. Finally, we provide feedback from a FTTH pilot network in Colmar (France) based on Gigabit Ethernet PON technology. The interest of this pilot lies on the level of functionality required for broadband optical access networks but also on the development of new home network configurations.

    2008-12-01

    There are over two billion telephones in use worldwide. Yet, for millions of Americans with intellectual disabilities (ID), access to the benefits of cellphone technology is limited because of deficits in literacy, numerical comprehension, the proliferation of features and shrinking size of cellphone hardware and user interfaces. Developments in smart phone technology and PDA-based cellphones provide an opportunity to make the social and safety benefits of cellphones more independently accessible to this population. This project involved employment of universal design and other specialised software development methods to create a multimedia cellphone interface prototype which was compared with a typical mainstream cellphone in a usability evaluation for individuals with ID. Participants completed a structured set of incoming/outgoing phone tasks using both the experimental and control conditions. Usability measurements included the amount of assistance needed and errors made in completing the cellphone use sequence. A total of 22 individuals with ID participated in the research by engaging in a series of incoming and outgoing cellphone calls using both the multimedia cellphone prototype system and a mainstream Nokia 6360 cellphone. Test subjects required significantly less help (P = 0.001) and made significantly fewer errors (P < 0.001) when completing eight calls using the specialised multimedia phone system as compared with the mainstream phone. The statistical evidence of both usability results provide promising evidence of the feasibility of implementing universal design and other specialised software development methodologies for increasing independent access to the benefits of cellphone technologies for students and adults with ID. Issues related to designing cognitively accessible interfaces, study limitations and future directions are discussed.

  14. Technological advancements and Internet sexuality: does private access to the Internet influence online sexual behavior?

    2012-08-01

    The aim of this study was to investigate whether demographic characteristics and sexual behavior online and offline were associated with private, respectively, nonprivate access to the Internet in a Web sample of people who use the Internet for sexual purposes. A total of 1,913 respondents completed an online questionnaire about Internet sexuality, and 1,614 reported using the Internet for sexual purposes. The majority of these respondents reported having access to an Internet-connected computer no one else had access to (62 percent women and 70 percent men). The results showed that it is possible to differentiate between those who have access to an Internet-connected computer no one else has access to and those who have shared access to an Internet-connected computer. Not only did they differ in demographic characteristics, but also in the sexual activities they engaged in on the Internet. Different patterns were found for women and men. For example, men who had private access to Internet-connected computers were more likely than those who had shared access to seek information about sexual issues. Thus, having access to Internet computers no one else has access to may promote sexual knowledge and health for men. The results of this study along with the technological development implies that in future research, attention should be paid to where and how people access the Internet in relation to online behavior in general and online sexual behavior in particular.

    2001-03-01

    The existing acquisition cost for essential drugs in the Cook Islands, Kiribati, Marshall Islands, Nauru, Niue, Tuvalu, is sufficiently high to compromise equitable access to quality drug therapy. The difficulty of access is further compounded by problems of distance from drug manufacturers and suppliers, associated with inadequate transport and communication links. In some of the Small Island States of the Pacific, internal distribution challenges further reduce access to drugs for those people who live on the outer islands. Two management processes to address these problems which have successfully been used in the past, are the establishment of an essential drug list to guarantee consistent appropriate treatment, and the introduction of pooled or bulk purchasing in order to achieve economies of scale. The major non-communicable diseases (NCDs) in the South Pacific include diabetes, hypertension and cardiovascular disease. These diseases, in association with life-style factors of obesity and smoking result in significant morbidity and mortality. This paper demonstrates that collaboration in drug purchasing of a defined list of essential drugs for hypertension would be beneficial in the South Pacific, and that the process is a model for achievement of rational drug treatment for NCDs in isolated small economies.

    This study fills demand for data on access and use of information and communication technologies (ICT) in the Brazilian legal Amazon, a region of localities with identical economic, political, and social problems. We use the 2010 Brazilian Demographic Census to compile data on urban and rural households (i) with computers and Internet access, (ii) with mobile phones, and (iii) with fixed phones. To compare the concentration of access to ICT in the municipalities of the Brazilian Amazon with other regions of Brazil, we use a concentration index to quantify the concentration of households in the following classes: with computers and Internet access, with mobile phones, with fixed phones, and no access. These data are analyzed along with municipal indicators on income, education, electricity, and population size. The results show that for urban households, the average concentration in the municipalities of the Amazon for computers and Internet access and for fixed phones is lower than in other regions of the country; meanwhile, that for no access and mobile phones is higher than in any other region. For rural households, the average concentration in the municipalities of the Amazon for computers and Internet access, mobile phones, and fixed phones is lower than in any other region of the country; meanwhile, that for no access is higher than in any other region. In addition, the study shows that education and income are determinants of inequality in accessing ICT in Brazilian municipalities and that the existence of electricity in rural households is directly associated with the ownership of ICT resources.

    2008-01-01

    The near universal deployment in the United States of a wide variety of information and communications technologies, both wired and wireless, creates potential barriers to use for several key populations, including the poor, people with disabilities, and the aging. Equal access to wireless technologies and services can be achieved through a variety of mechanisms, including legislation and regulations, market-based solutions, and awareness and outreach-based approaches. This article discusses the results of policy research conducted by the Rehabilitation Engineering Research Center on Wireless Technologies (Wireless RERC) using policy Delphi polling methodology to probe stakeholders' opinions on key access barrier issues and to explore potential policy responses. Participants included disability advocates, disability/wireless technology policy makers, and product developers/manufacturers. Respondent input informed subsequent development of potential policy initiatives to increase access to these technologies. The findings from the Delphi suggest that awareness issues remain most important, especially manufacturer awareness of user needs and availability of consumer information for selecting the most appropriate wireless devices and services. Other key issues included the ability of people with disabilities to afford technologies and inadequacies in legislation and policy making for ensuring their general accessibility, as well as usefulness in emergencies. Technical issues, including interoperability, speech-to-text conversion, and hearing aid compatibility, were also identified by participating stakeholders as important. To address all these issues, Delphi respondents favored goals and options congruent with voluntary market-driven solutions where possible but also supported federal involvement, where necessary, to aid this process.

    2010-01-01

    The need for a high specific impulse LOX/LH2 pump-fed lunar lander engine has been established by NASA for the new lunar exploration architecture. Studies indicate that a 4-engine cluster in the thrust range of 9,000-lbf each is a candidate configuration for the main propulsion of the manned lunar lander vehicle. The lander descent engine will be required to perform multiple burns including the powered descent onto the lunar surface. In order to achieve the wide range of thrust required, the engines must be capable of throttling approximately 10:1. Working under internal research and development funding, NASA Marshall Space Flight Center (MSFC) has been conducting the development of a 9,000-lbf LOX/LH2 lunar lander descent engine technology testbed. This paper highlights the detailed design and analysis efforts to develop the lander engine Fuel Turbopump (FTP) whose operating speeds range from 30,000-rpm to 100,000-rpm. The capability of the FTP to operate across this wide range of speeds imposes several structural and dynamic challenges, and the small size of the FTP creates scaling and manufacturing challenges that are also addressed in this paper.

    The 2012 World Health Assembly Global Vaccine Action Plan called for global access to new vaccines within 5 years of licensure. Current approaches have proven insufficient to achieve sustainable vaccine pricing within such a timeline. Paralleling the successful strategy of generic competition to bring down drug prices, a clear consensus is emerging that market entry of multiple suppliers is a critical factor in expeditiously bringing down prices of new vaccines. In this context, key target objectives for improving access to new vaccines include overcoming intellectual property obstacles, streamlining regulatory pathways for biosimilar vaccines, and reducing market entry timelines for developing-country vaccine manufacturers by transfer of technology and know-how. I propose an intellectual property, technology, and know-how bank as a new approach to facilitate widespread access to new vaccines in low- and middle-income countries by efficient transfer of patented vaccine technologies to multiple developing-country vaccine manufacturers.

    2014-12-01

    Abstract Objective: To investigate the evolving use and expected impact of pay-for-performance (P4P) and risk-based provider reimbursement on patient access to innovative medical technology. Structured interviews with leading private payers representing over 110 million commercially-insured lives exploring current and planned use of P4P provider payment models, evidence requirements for technology assessment and new technology coverage, and the evolving relationship between the two topics. Respondents reported rapid increases in the use of P4P and risk-sharing programs, with roughly half of commercial lives affected 3 years ago, just under two-thirds today, and an expected three-quarters in 3 years. All reported well-established systems for evaluating new technology coverage. Five of nine reported becoming more selective in the past 3 years in approving new technologies; four anticipated that in the next 3 years there will be a higher evidence requirement for new technology access. Similarly, four expected it will become more difficult for clinically appropriate but costly technologies to gain coverage. All reported planning to rely more on these types of provider payment incentives to control costs, but didn't see them as a substitute for payer technology reviews and coverage limitations; they each have a role to play. Interviews limited to nine leading payers with models in place; self-reported data. Likely implications include a more uncertain payment environment for providers, and indirectly for innovative medical technology and future investment, greater reliance on quality and financial metrics, and increased evidence requirements for favorable coverage and utilization decisions. Increasing provider financial risk may challenge the traditional technology adoption paradigm, where payers assumed a 'gatekeeping' role and providers a countervailing patient advocacy role with regard to access to new technology. Increased provider financial risk may result in an

    2001-03-01

    Our goal was to investigate policy on patient access to services at assisted reproductive technology clinics in the United States. Surveys asked about a variety of ethically and socially challenging cases and were mailed to directors of all Society for Assisted Reproductive Technology-associated assisted reproductive technology clinics. Written policies on access to services are present at 40% of assisted reproductive technology clinics. Universal agreement was not found on any issue; 79% of clinics treat single women, 27% treat patients with a history of schizophrenia, 10% treat patients who use alcohol excessively, 7% treat human immunodeficiency virus-positive women, and 2% would treat patients previously convicted of child abuse. A breakdown of the responses indicated that some clinics are more permissive in terms of access to services than others, whereas some are more restrictive. The data demonstrate considerable variability in policy among clinics on most access-to-services questions. The results highlight the importance of ongoing discussion of the ethical and legal issues related to access and the need to develop consistent methods to deal with complex cases.

    Background Providing patients with access to their medical data is widely expected to help educate and empower them to manage their own health. Health information exchange (HIE) infrastructures could potentially help patients access records across multiple healthcare providers. We studied three HIE organizations as they developed portals to give consumers access to HIE data previously exchanged only among healthcare organizations. Objective To follow the development of new consumer portal technologies, and to identify barriers and facilitators to patient access to HIE data. Methods Semistructured interviews of 15 key informants over a 2-year period spanning the development and early implementation of three new projects, coded according to a sociotechnical framework. Results As the organizations tried to develop functionality that fully served the needs of both providers and patients, plans were altered by technical barriers (primarily related to data standardization) and cultural and legal issues surrounding data access. Organizational changes also played an important role in altering project plans. In all three cases, patient access to data was significantly scaled back from initial plans. Conclusions This prospective study revealed how sociotechnical factors previously identified as important in health information technology success and failure helped to shape the evolution of three novel consumer informatics projects. Barriers to providing patients with seamless access to their HIE data were multifactorial. Remedies will have to address technical, organizational, cultural, and other factors. PMID:24064443

    ABSTRACT We surveyed 146 postpartum women who birthed at 34–37 6/7 weeks of gestation and intended to breastfeed about their use of and preferences regarding technology to obtain perinatal and breastfeeding support. Most participants owned smartphones and used technology during pregnancy to track pregnancy data, follow fetal development, address pregnancy concerns, and obtain breastfeeding information. Internet, e-mail, apps, and multiplatform resources were the most popular technologies used and preferred. Demographic differences existed in mobile technology access and preferences for different technologies. In terms of technology-based breastfeeding support, women wanted encouragement, anticipatory guidance, and information about milk production. A nuanced understanding of the technology childbearing women use and desire has the potential to impact clinical care and inform perinatal support interventions. PMID:26848248

But even though the so-called "Last Mile Access Bottleneck" is well known since more than ten years and many distribution technologies have been tried out, the optimal solution has not yet been found and paying commercial access networks offering all service classes are still rare today. Conventional services like telephone, radio and TV, as well as new and emerging services like email, web browsing, online-gaming, video conferences, business data transfer or external data storage can all be transmitted over the well known and cost effective Ethernet networking protocol standard. Key requirements for the deployment technology driven by the different services are high data rates to the single customer, security, moderate deployment costs and good scalability to number and density of users, quick and flexible deployment without legal impediments and high availability, referring to the properties of optical and wireless communication. We demonstrate all elements of an Ethernet Access Network based on Free Space Optic distribution technology. Main physical parts are Central Office, Distribution Network and Customer Equipment. Transmission of different services, as well as configuration, service upgrades and remote control of the network are handled by networking features over one FSO connection. All parts of the network are proven, the latest commercially available technology. The set up is flexible and can be adapted to any more specific need if required.

    There is a need to understand how technology can best be used to facilitate well-being in people with dementia. This study sought to describe how access control technology influenced the everyday lives of people with dementia living in a secure unit. The staff members and the unit's residents participated in the study. Data were collected through ethnographic observations and semi-structured interviews over 6 months, and were analyzed using the constant comparative method. The results show how access technology supported the residents' sense of security, territoriality, orientation, and adaptation to the environment. However, certain conditions were necessary for these influences to appear. Overall, the results indicate that access control technology may be used to support the well-being of people with dementia, and to increase their opportunities to feel in place in a secure unit. However, there is an urgent need in the future for further exploration of the conditions for use of technology in the field of dementia care, and the necessity of making careful evaluations of the use of technology in this field cannot be overemphasized.

  10. Logical optical line terminal technologies towards flexible and highly reliable metro- and access-integrated networks

    NASA Astrophysics Data System (ADS)

    Okamoto, Satoru; Sato, Takehiro; Yamanaka, Naoaki

    2017-01-01

    In this paper, flexible and highly reliable metro and access integrated networks with network virtualization and software defined networking technologies will be presented. Logical optical line terminal (L-OLT) technologies and active optical distribution networks (ODNs) are the key to introduce flexibility and high reliability into the metro and access integrated networks. In the Elastic Lambda Aggregation Network (EλAN) project which was started in 2012, a concept of the programmable optical line terminal (P-OLT) has been proposed. A role of the P-OLT is providing multiple network services that have different protocols and quality of service requirements by single OLT box. Accommodated services will be Internet access, mobile front-haul/back-haul, data-center access, and leased line. L-OLTs are configured within the P-OLT box to support the functions required for each network service. Multiple P-OLTs and programmable optical network units (P-ONUs) are connected by the active ODN. Optical access paths which have flexible capacity are set on the ODN to provide network services from L-OLT to logical ONUs (L-ONUs). The L-OLT to L-ONU path on the active ODN provides a logical connection. Therefore, introducing virtualization technologies becomes possible. One example is moving an L-OLT from one P-OLT to another P-OLT like a virtual machine. This movement is called L-OLT migration. The L-OLT migration provides flexible and reliable network functions such as energy saving by aggregating L-OLTs to a limited number of P-OLTs, and network wide optical access path restoration. Other L-OLT virtualization technologies and experimental results will be also discussed in the paper.

    This study fills demand for data on access and use of information and communication technologies (ICT) in the Brazilian legal Amazon, a region of localities with identical economic, political, and social problems. We use the 2010 Brazilian Demographic Census to compile data on urban and rural households (i) with computers and Internet access, (ii) with mobile phones, and (iii) with fixed phones. To compare the concentration of access to ICT in the municipalities of the Brazilian Amazon with other regions of Brazil, we use a concentration index to quantify the concentration of households in the following classes: with computers and Internet access, with mobile phones, with fixed phones, and no access. These data are analyzed along with municipal indicators on income, education, electricity, and population size. The results show that for urban households, the average concentration in the municipalities of the Amazon for computers and Internet access and for fixed phones is lower than in other regions of the country; meanwhile, that for no access and mobile phones is higher than in any other region. For rural households, the average concentration in the municipalities of the Amazon for computers and Internet access, mobile phones, and fixed phones is lower than in any other region of the country; meanwhile, that for no access is higher than in any other region. In addition, the study shows that education and income are determinants of inequality in accessing ICT in Brazilian municipalities and that the existence of electricity in rural households is directly associated with the ownership of ICT resources.

    The Department of Veterans Affairs (VA) has been at the vanguard of information technology (IT) and use of comprehensive electronic health records. Despite the widespread use of health IT in the VA, there are still a variety of key questions that need to be answered in order to maximize the utility of IT to improve patient access to quality services. This paper summarizes the potential of IT to enhance healthcare access, key gaps in current evidence linking IT and access, and methodologic challenges for related research. We also highlight four key issues to be addressed when implementing and evaluating the impact of IT interventions on improving access to quality care: 1) Understanding broader needs/perceptions of the Veteran population and their caregivers regarding use of IT to access healthcare services and related information. 2) Understanding individual provider/clinician needs/perceptions regarding use of IT for patient access to healthcare. 3) System/Organizational issues within the VA and other organizations related to the use of IT to improve access. 4) IT integration and information flow with non-VA entities. While the VA is used as an example, the issues are salient for healthcare systems that are beginning to take advantage of IT solutions.

    The evolution in information and telecommunication technologies has allowed the development of systems that use the Internet infrastructure and Web technology to remotely access a hospital's picture archiving and communication system (PACS). However, one of the main problems in the construction of this type of system is the development of mechanisms that guarantee the security of the medical data that are being consulted. Most countries have specific norms for the protection of such medical data. This work describes security mechanisms that are developed in an access system to PACS DICOM with Web technology and comply with the Spanish legislation concerning the protection of medical data. The proposed security mechanisms are flexible, they leave room for the definition of security policies adjusted to the needs of each particular organization and they can be adapted to comply with new or foreign norms.

    The Technology Information Environment with Industry (TIE-In) is a system that helps users obtain laboratory-developed technical solutions without requiring that they duplicate the technical resources (in people, hardware and software) at the national laboratories. TIE-In is based on providing users with controlled access to distributed laboratory resources that are packaged in intelligent user interfaces. These interfaces help users obtain technical solutions without requiring that the user have specialized technical and computer expertise. As a designated DOE Technology Deployment Center/User Facility, industry users can access a broad range of laboratory-developed technologies on a cost-recovery basis. TIE-In will also be used to share laboratory resources with partners in US industry that help the DOE meet future manufacturing needs for the stewardship of our nation`s nuclear weapons stockpile.

    The main problem for health professionals and patients in accessing information is that this information is very often distributed over many medical records and locations. This problem is particularly acute in cancerology because patients may be treated for many years and undergo a variety of examinations. Recent advances in technology make it feasible to gain access to medical records anywhere and anytime, allowing the physician or the patient to gather information from an “ephemeral electronic patient record”. However, this easy access to data is accompanied by the requirement for improved security (confidentiality, traceability, integrity, ...) and this issue needs to be addressed. In this paper we propose and discuss a decentralised approach based on recent advances in information sharing and protection: Grid technologies and watermarking methodologies. The potential impact of these technologies for oncology is illustrated by the examples of two experimental cases: a cancer surveillance network and a radiotherapy treatment plan. It is expected that the proposed approach will constitute the basis of a future secure “google-like” access to medical records. PMID:19718446

    Background Age and race-related disparities in technology use have been well documented, but less is known about how health literacy influences technology access and use. Objective To assess the association between patients’ literacy skills and mobile phone ownership, use of text messaging, internet access, and use of the internet for health-related purposes. Methods A secondary analysis utilizing data from 1,077 primary care patients enrolled in two, multi-site studies from 2011–2013. Patients were administered an in-person, structured interview. Results Patients with adequate health literacy were more likely to own a mobile phone or smartphone in comparison to patients with low or marginal literacy (mobile phone ownership: 96.8% vs. 95.2% vs. 90.1%, respectively, p<.001; smartphone ownership: 70.6% vs. 62.5% vs. 40.1%, p<.001) and to report text messaging (78.6% vs. 75.2% vs. 53.1%, p<.001). They were also more likely to have access to the internet from their home (92.1% vs. 74.7% vs. 44.9%, p<.001) and to report using the internet for email (93.0% vs. 75.7% vs. 38.5%, p<.001), browsing the web (93.9% vs. 80.2% vs. 44.5%, p<.001), accessing health information (86.3% vs. 75.5% vs. 40.8%, p<.001), and communicating with providers (54.2% vs. 29.8% vs. 13.0%, p<.001). Relationships remained significant in multivariable analyses controlling for relevant covariates. Conclusions Results reveal that literacy-related disparities in technology access and use are widespread, with lower literate patients being less likely to own smartphones or to access and use the internet, particularly for health reasons. Future interventions should consider these disparities and ensure that health promotion activities do not further exacerbate disparities. PMID:25363660

    Background Patient access to clinical information represents a means to improve the transparency and delivery of health care as well as interactions between patients and health care providers. We examine the movement toward augmenting patient access to clinical information using technology. Our analysis focuses on “Blue Button,” a tool that many health care organizations are implementing as part of their Web-based patient portals. Objective We present a framework for evaluating the effects that technology-assisted access to clinical information may have on stakeholder experiences, processes of care, and health outcomes. Methods A case study of the United States Department of Veterans Affairs' (VA) efforts to make increasing amounts of clinical information available to patients through Blue Button. Drawing on established collaborative relationships with researchers, clinicians, and operational partners who are engaged in the VA’s ongoing implementation and evaluation efforts related to Blue Button, we assessed existing evidence and organizational practices through key informant interviews, review of documents and other available materials, and an environmental scan of published literature and the websites of other health care organizations. Results Technology-assisted access to clinical information represents a significant advance for VA patients and marks a significant change for the VA as an organization. Evaluations of Blue Button should (1) consider both processes of care and outcomes, (2) clearly define constructs of focus, (3) examine influencing factors related to the patient population and clinical context, and (4) identify potential unintended consequences. Conclusions The proposed framework can serve as a roadmap to guide subsequent research and evaluation of technology-assisted patient access to clinical information. To that end, we offer a series of related recommendations. PMID:24675395

    The United States (US) has a large correctional population. However, many incarcerated persons lack access to evidence-based, up-to-date medical care, particularly by subspecialty providers, due to limitations of geography, travel, cost and other resources. The use of telehealth technologies can remove these barriers, increasing access to high quality, multidisciplinary care. Studies have shown that, with telemedicine, timely triage and medical management can be provided across many disciplines, which may lead to improved clinical outcomes and significant cost savings.

    Assistive technology for computer access can be used to facilitate people with a spinal cord injury to utilize mainstream computer applications, thereby enabling participation in a variety of meaningful occupations. The aim of this study was to gain an understanding of the experiences of clients with tetraplegia trialing assistive technologies for computer access during different stages in a public rehabilitation service. In order to explore the experiences of clients with tetraplegia trialing assistive technologies for computer use, qualitative methodology was selected. Data were collected from seven participants using semi-structured interviews, which were audio-taped, transcribed and analyzed thematically. Three main themes were identified. These were: getting back into life, assisting in adjusting to injury and learning new skills. The findings from this study demonstrated that people with tetraplegia can be assisted to return to previous life roles or engage in new roles, through developing skills in the use of assistive technology for computer access. Being able to use computers for meaningful activities contributed to the participants gaining an enhanced sense of self-efficacy, and thereby quality of life. Implications for Rehabilitation Findings from this pilot study indicate that people with tetraplegia can be assisted to return to previous life roles, and develop new roles that have meaning to them through the use of assistive technologies for computer use. Being able to use the internet to socialize, and complete daily tasks, contributed to the participants gaining a sense of control over their lives. Early introduction to assistive technology is important to ensure sufficient time for newly injured people to feel comfortable enough with the assistive technology to use the computers productively by the time of discharge. Further research into this important and expanding area is indicated.

    In recent years, the effect of urban heat island (UHI) is increasingly obvious with moving forward in further urbanization process, which has become one of the prominent issues of environment. The image data of Nanchang city supplied by Landsat 5 Thematic Mapper (TM) in September 2006 is used in this paper, and the land surface temperature (LST) over the same period has been retrieved by using a mono-window algorithm based on remote sensing technology. The classification of LST is subsequently fulfilled by the method of proper density cutting. Characteristics of intensity and spatial distribution of UHI effect in Nanchang, as well as its relationships with land use type and vegetation coverage degree (VCD) are discussed in detail. The result shows that the phenomena of UHI are significantly presented in urban area with an inhomogeneous distribution, and the degree of influence of UHI depends on types of land uses. The intensity of UHI effect has a significant negative linear correlation with normalized difference vegetation index (NDVI). It is deduced that suitably optimizing land use types and raising VCR are obvious and effective ways to reduce UHI.

    Wave energy fluctuating a great deal endangers the security of power grid especially micro grid in island. A DC nano grid supported by batteries is proposed to smooth the output power of wave energy converters (WECs). Thus, renewable energy converters connected to DC grid is a new subject. The characteristics of WECs are very important to the connection technology of HPTO type WECs and DC nano grid. Hydraulic power take-off system (HPTO) is the core unit of the largest category of WECs, with the functions of supplying suitable damping for a WEC to absorb wave energy, and converting captured wave energy to electricity. The HPTO is divided into a hydraulic energy storage system (HESS) and a hydraulic power generation system (HPGS). A primary numerical model for the HPGS is established in this paper. Three important basic characteristics of the HPGS are deduced, which reveal how the generator load determines the HPGS rotation rate. Therefore, the connector of HPTO type WEC and DC nano grid would be an uncontrollable rectifier with high reliability, also would be a controllable power converter with high efficiency, such as interleaved boost converter-IBC. The research shows that it is very flexible to connect to DC nano grid for WECs, but bypass resistance loads are indispensable for the security of WECs.

    Most parts of present computer systems are made of volatile devices, and the power to supply them to avoid information loss causes huge energy losses. We can eliminate this meaningless energy loss by utilizing the non-volatile function of advanced spin-transfer torque magnetoresistive random-access memory (STT-MRAM) technology and create a new type of computer, i.e., normally off computers. Critical tasks to achieve normally off computers are implementations of STT-MRAM technologies in the main memory and low-level cache memories. STT-MRAM technology for applications to the main memory has been successfully developed by using perpendicular STT-MRAMs, and faster STT-MRAM technologies for applications to the cache memory are now being developed. The present status of STT-MRAMs and challenges that remain for normally off computers are discussed.

    The Policy RECommendations for Open Access to Research Data in Europe (RECODE) project, started in February 2013 with a duration of two years, has the objective to identify a series of targeted and over-arching policy recommendations for Open Access to European research data, based on existing good practice and addressing such hindering factors as stakeholder fragmentation, technical and infrastructural issues, ethical and legal issues, and financial and institutional policies. In this work we focus on the technical and infrastructural aspect, where by "infrastructure" we mean the technological assets (hardware and software), the human resources, and all the policies, processes, procedures and training for managing and supporting its continuous operation and evolution. The context targeted by RECODE includes heterogeneous networks, initiatives, projects and communities that are fragmented by discipline, geography, stakeholder category (publishers, academics, repositories, etc.) as well as other boundaries. Many of these organizations are already addressing key technical and infrastructural barriers to Open Access to research data. Such barriers may include: lack of automatic mechanisms for policy enforcement, lack of metadata and data models supporting open access, obsolescence of infrastructures, scarce awareness about new technological solutions, lack of training and/or expertise on IT and semantics aspects. However, these organizations are often heterogeneous and fragmented by discipline, geography, stakeholder category (publishers, academics, repositories, etc.) as well as other boundaries, and often work in isolation, or with limited contact with one another. RECODE has addressed these challenges, and the possible solutions to mitigate them, engaging all the identified stakeholders in a number of ways, including an online questionnaire, case studies interviews, literature review, a workshop. The conclusions have been validated by the RECODE Advisory Board and

    Fission technology can enable rapid, affordable access to any point in the solar system. Potential fission-based transportation options include bimodal nuclear thermal rockets, high specific energy propulsion systems, and pulsed fission propulsion systems. In-space propellant re-supply enhances the effective performance of all systems, but requires significant infrastructure development. Safe, timely, affordable utilization of first-generation space fission propulsion systems will enable the development of more advanced systems. First generation systems can build on over 45 years of US and international space fission system technology development to minimize cost.

    Digital technologies offer new platforms for health promotion and disease management. Few studies have evaluated the use of digital technology among families receiving care in an urban pediatric primary care setting. A self-administered survey was given to a convenience sample of caregivers bringing their children to 2 urban pediatric primary care centers in spring 2012. The survey assessed access to home Internet, e-mail, smartphone, and social media (Facebook and Twitter). A "digital technology" scale (0-4) quantified the number of available digital technologies and connections. Frequency of daily use and interest in receiving medical information digitally were also assessed. The survey was completed by 257 caregivers. The sample was drawn from a clinical population that was 73% African American and 92% Medicaid insured with a median patient age of 2.9 years (interquartile range 0.8-7.4). Eighty percent of respondents reported having Internet at home, and 71% had a smartphone. Ninety-one percent reported using e-mail, 78% Facebook, and 27% Twitter. Ninety-seven percent scored ≥1 on the digital technology scale; 49% had a digital technology score of 4. The digital technology score was associated with daily use of digital media in a graded fashion (P < .0001). More than 70% of respondents reported that they would use health care information supplied digitally if approved by their child's medical provider. Caregivers in an urban pediatric primary care setting have access to and frequently use digital technologies. Digital connections may help reach a traditionally hard-to-reach population.

    For an interactive application, supporting and guiding the user in fulfilling tasks is most important. The behavior of the application that will guide users through the procedures until they finish the task has to be designed intuitively and well guiding, especially if the users has only restricted or no access to the visual and spatial arrangement on the screen. Therefore, the focus/cursor management plays an important role for orientation and navigating through the interaction. In the frame of ongoing research on a software tool supporting blind people in more efficiently doing mathematical calculations, we researched how Java technologies support implementing an accessible Graphical User Interface (GUI) with an additional focus on usable accessibility in terms of guiding blind users through the process of solving mathematical calculations. We used Java Swing [1] and Eclipse SWT [2] APIs for creating a series of prototypes. We tested a) accessibility and usability of the prototypes for blind people when using screen reader software and refreshable Braille display and b) the implementation support to developers provided by both technologies. It turned out that Eclipse SWT API delivered best results under Windows operating system.

    Is there any ethical justification for limiting the reproductive autonomy and not make assisted reproductive technologies available to certain prospective parents? We present and discuss the results of an interdisciplinary clinical ethics study concerning access to assisted reproductive technologies (ART) in situations which are considered as ethically problematic in France (overage or sick parents, surrogate motherhood). The study focused on the arguments that people in these situations put forward when requesting access to ART. It shows that requester's arguments are based on sound ethical values, and that their legitimacy is at least as strong as that of those used by doctors to question access to ART. Results reveal that the three implicit normative arguments that founded the law in 1994, which are still in force after the bioethics law revision in July 2011-the welfare of the child, the illegitimacy of a "right to a child," and the defense of the so called "social order"-are challenged on several grounds by requesters as reasons for limiting their reproductive autonomy. Although these results are limited to exceptional situations, they are of special interest insofar as they give voice to the requesters' own ethical concerns in the ongoing political debate over access to ART.

    The increasing volume, complexity, and heterogeneity of scientific data are posing challenges to public access to data. These challenges also affect the assessment of impact and accountability. Yet, we are beginning to see that a confluence of standards and best practices can lead to improved accessibility and increased sustainability. We present examples of how Linked Open Data, standards, and best practices are being used to automate the linking of heterogeneous datasets as well as link data to publication. Specifically, we highlight our work in making data from the oceanographic community, the National Science Foundation, and professional societies, including the AGU and the Earth Science Information Partnership, more connected and more easily accessible and usable. We highlight the benefits of emerging semantic technologies, which enable automated reasoning and we show examples from the oceanographic research community. We discuss how technologies, standards, and best practices are leading to improvements in finding, accessing, and using data and publications. Finally, we demonstrate how these techniques and standards are being used to promote sustainable and scalable data repositories.

  20. Math and science technology access and use in South Dakota public schools grades three through five

    Schwietert, Debra L.

    The development of K-12 technology standards, soon to be added to state testing of technology proficiency, and the increasing presence of computers in homes and classrooms reflects the growing importance of technology in current society. This study examined math and science teachers' responses on a survey of technology use in grades three through five in South Dakota. A researcher-developed survey instrument was used to collect data from a random sample of 100 public schools throughout the South Dakota. Forced choice and open-ended responses were recorded. Most teachers have access to computers, but they lack resources to purchase software for their content areas, especially in science areas. Three-fourths of teachers in this study reported multiple computers in their classrooms and 67% reported access to labs in other areas of the school building. These numbers are lower than the national average of 84% of teachers with computers in their classrooms and 95% with access to computers elsewhere in the building (USDOE, 2000). Almost eight out of 10 teachers noted time as a barrier to learning more about educational software. Additional barriers included lack of school funds (38%), access to relevant training (32%), personal funds (30%), and poor quality of training (7%). Teachers most often use math and science software as supplemental, with practice tutorials cited as another common use. The most common interest for software was math for both boys and girls. The second most common choice for boys was science and for girls, language arts. Teachers reported that there was no preference for either individual or group work on computers for girls or boys. Most teachers do not systematically evaluate software for gender preferences, but review software over subjectively.

  2. Technology access from the FS-X radar program. Lessons for technology transfer and US acquisition policy

    NASA Astrophysics Data System (ADS)

    Chang, Ike Y., Jr.

    The FS-X is a cooperative aircraft development program launched in 1989 between the United States and Japan. The FS-X program entitles the U.S. government and U.S. industry access to Japanese FS-X technology. This report explores the issue of U.S. access and possible licensed transfer of Japanese FS-X radar technology for use by the U.S. government and industry. The FS-X radar program is significant in that it may be the first program to develop an operational active phased array radar (APAR) for airborne fire control. APAR technology has the benefits of superior performance, rehability, and maintainability. Nevertheless, because of stringent U.S. program requirements and high production costs, APAR has not yet become an operational reality in the United States. The FS-X is, therefore, important in that it may signify growing strengths of Japan in a technical area historically dominated by U.S. firms.

    The incorporation of new treatments, procedures and technologies into the services' portfolio of healthcare providers should aim to improve three areas equally: patient access to innovative solutions, the sustainability of the health system and compensation for innovation. However, traditional schemes based on fixed prices that fail to consider the product's appropriate use or its results in terms of effectiveness may lead to inefficient decision-making processes. Recently, risk-sharing agreements have appeared as new access schemes based on results that aim to reduce the uncertainty of the distinct health care players involved in reaching an agreement on new health technology financing and conditions of use. Key elements in the debate on these instruments are the huge variety of instruments available (especially those based on results), the implications for different players involved in their design and supervision, and their possible implementation in Spain. Our main conclusion is that risk-sharing agreements should be used in highly limited cases when standard conditions of access cannot be applied due to uncertainty about long-term effectiveness. These measures are aimed not only at regulating price but also at acting on the appropriate use of new technology. However, because international experience is limited, drawing a solid conclusion on the final results of the application of risk-sharing agreements would be premature. Copyright © 2010 SESPAS.

    Molecular diagnostics can offer important benefits to patients and are a key enabler of the integration of personalised medicine into health care systems. However, despite their promise, few molecular diagnostics are embedded into clinical practice (especially in Europe) and access to these technologies remains unequal across countries and sometimes even within individual countries. If research translation and the regulatory environments have proven to be more challenging than expected, reimbursement and value assessment remain the main barriers to providing patients with equal access to molecular diagnostics. Unclear or non-existent reimbursement pathways, together with the lack of clear evidence requirements, have led to significant delays in the assessment of molecular diagnostics technologies in certain countries. Additionally, the lack of dedicated diagnostics budgets and the siloed nature of resource allocation within certain health care systems have significantly delayed diagnostics commissioning. This article will consider the perspectives of different stakeholders (patients, health care payers, health care professionals, and manufacturers) on the provision of a research-enabled, patient-focused molecular diagnostics platform that supports optimal patient care. Through the discussion of specific case studies, and building on the experience from countries that have successfully integrated molecular diagnostics into clinical practice, this article will discuss the necessary evolutions in policy and health technology assessment to ensure that patients can have equal access to appropriate molecular diagnostics.

    In 2015, 90% of US young adults with Internet access used social media. Digital and social media are highly prevalent modalities through which young adults explore identity formation, and by extension, learn and transmit norms about health and risk behaviors during this developmental life stage. The purpose of this study was to provide updated estimates of social media use from 2014 to 2016 and correlates of social media use and access to digital technology in data collected from a national sample of US young adults in 2016. Young adult participants aged 18-24 years in Wave 7 (October 2014, N=1259) and Wave 9 (February 2016, N=989) of the Truth Initiative Young Adult Cohort Study were asked about use frequency for 11 social media sites and access to digital devices, in addition to sociodemographic characteristics. Regular use was defined as using a given social media site at least weekly. Weighted analyses estimated the prevalence of use of each social media site, overlap between regular use of specific sites, and correlates of using a greater number of social media sites regularly. Bivariate analyses identified sociodemographic correlates of access to specific digital devices. In 2014, 89.42% (weighted n, 1126/1298) of young adults reported regular use of at least one social media site. This increased to 97.5% (weighted n, 965/989) of young adults in 2016. Among regular users of social media sites in 2016, the top five sites were Tumblr (85.5%), Vine (84.7%), Snapchat (81.7%), Instagram (80.7%), and LinkedIn (78.9%). Respondents reported regularly using an average of 7.6 social media sites, with 85% using 6 or more sites regularly. Overall, 87% of young adults reported access or use of a smartphone with Internet access, 74% a desktop or laptop computer with Internet access, 41% a tablet with Internet access, 29% a smart TV or video game console with Internet access, 11% a cell phone without Internet access, and 3% none of these.

    Technology and connectivity advances are demonstrating increasing potential to improve access of service delivery to persons with hearing loss. This article demonstrates use cases from community-based hearing screening and automated diagnosis of ear disease. This brief report reviews recent evidence for school- and home-based hearing testing in underserved communities using smartphone technologies paired with calibrated headphones. Another area of potential impact facilitated by technology and connectivity is the use of feature extraction algorithms to facilitate automated diagnosis of most common ear conditions from video-otoscopic images. Smartphone hearing screening using calibrated headphones demonstrated equivalent sensitivity and specificity for school-based hearing screening. Automating test sequences with a forced-choice response paradigm allowed persons with minimal training to offer screening in underserved communities. The automated image analysis and diagnosis system for ear disease demonstrated an overall accuracy of 80.6%, which is up to par and exceeds accuracy rates previously reported for general practitioners and pediatricians. The emergence of these tools that capitalize on technology and connectivity advances enables affordable and accessible models of service delivery for community-based ear and hearing care.

    The Public Intellectual Property Resource for Agriculture (PIPRA) was founded in 2004 by the Rockefeller Foundation in response to concerns that public investments in agricultural biotechnology benefiting developing countries were facing delays, high transaction costs and lack of access to important technologies due to intellectual property right (IPR) issues. From its inception, PIPRA has worked broadly to support a wide range of research in the public sector, in specialty and minor acreage crops as well as crops important to food security in developing countries. In this paper, we review PIPRA's work, discussing the failures, successes, and lessons learned during its years of operation. To address public sector's limited freedom-to-operate, or legal access to third-party rights, in the area of plant transformation, we describe PIPRA's patent 'pool' approach to develop open-access technologies for plant transformation which consolidate patent and tangible property rights in marker-free vector systems. The plant transformation system has been licensed and deployed for both commercial and humanitarian applications in the United States (US) and Africa, respectively. © 2012 The Authors.

    The need to progress and innovate in health technology assessment (HTA) is a must in a continuously changing environment. The HTAi Policy Forum reflected on two specific areas for development where it was thought there was need for careful consideration and deliberation during the main annual meeting in February 2016. The study by Husereau et al. (1) in this journal presents the discussions resulting from this Forum. To further share the deliberations of the Forum and with a view to opening this debate to the wider HTA community, a panel session during the HTAi Annual Meeting in Tokyo was organized. Presentations at the panel included a summary of the HTAi Policy Forum discussions and perspectives from a patient, a representative of healthcare system provider, and a representative from an HTA organization and industry. This letter presents the issues raised in the panel session.

  12. Isolated Islands by Selective Local Oxidation (islo): a Silicon-On (soi) Technology for Nanoelectronic and Nanoelectromechanical Applications.

    NASA Astrophysics Data System (ADS)

    Arney, Susanne Christine

    The development of an advanced fully-integrated nanometer-scale isolation technology called the Isolated Islands of Substrate-Silicon by Selective Lateral Oxidation (ISLO) technology is reported. The versatility and applicability of the ISLO technology for diverse nanoelectronic and nanoelectromechanical devices and systems are described relative to the challenging issues of isolation and contacts. The basic ISLO structure is fabricated using electron beam lithography and standard VLSI reactive ion etching and oxidation processes. Single crystal silicon (SCS) islands 100-300-nm-wide, and 500 -2000-nm-tall are electrically and thermally isolated from the underlying substrate by selective lateral thermal oxidation at the base of the islands. Dislocation-free fully-isolated islands are obtained. Full-isolation of the basic ISLO structure depends on island linewidth, oxidation-masking film thicknesses, recess etch profile, and oxidation time and temperature. The extended ISLO technology provides 100-nm-wide, movable, suspended, high stiffness, low mass, SCS or SCS-dielectric-composite beam segments with integrated electrical contacts and metallization for high frequency (5-10 MHz) nanodynamic applications. Fixed or cantilevered beam segments are isolated from the underlying substrate -silicon by thermally grown oxide or an air-bridge.

    Despite major national investments to support the adoption of health information technology (IT), concerns persist that barriers are inhibiting that adoption and the use of advanced health IT capabilities in rural areas in particular. Using a survey of Medicare-certified critical-access hospitals, we examined electronic health record (EHR) adoption, key EHR functionalities, telehealth, and teleradiology, as well as challenges to EHR adoption. In 2013, 89 percent of critical-access hospitals had implemented a full or partial EHR. Adoption of key EHR capabilities varied. Critical-access hospitals that had certain types of technical assistance and resources available to support health IT were more likely to have adopted health IT capabilities and less likely to report significant challenges to EHR implementation and use, compared to other hospitals in the survey. It is important to ensure that the necessary resources and support are available to critical-access hospitals, especially those that operate independently, to assist them in adopting health IT and becoming able to electronically link to the broader health care system.

  14. Developing hybrid near-space technologies for affordable access to suborbital space

    NASA Astrophysics Data System (ADS)

    Badders, Brian David

    High power rockets and high altitude balloons are two near-space technologies that could be combined in order to provide access to the mesosphere and, eventually, suborbital space. This "rockoon" technology has been used by several large budget space programs before being abandoned in favor of even more expensive, albeit more accurate, ground launch systems. With the increased development of nano-satellites and atmospheric sensors, combined with rising interest in global atmospheric data, there is an increase in desire for affordable access to extreme altitudes that does not necessarily require the precision of ground launches. Development of hybrid near-space technologies for access to over 200k ft. on a small budget brings many challenges within engineering, systems integration, cost analysis, market analysis, and business planning. This research includes the design and simulation testing of all the systems needed for a safe and reusable launch system, the cost analysis for initial production, the development of a business plan, and the development of a marketing plan. This project has both engineering and scientific significance in that it can prove the space readiness of new technologies, raise their technology readiness levels (TRLs), expedite the development process, and also provide new data to the scientific community. It also has the ability to stimulate university involvement in the aerospace industry and help to inspire the next generation of workers in the space sector. Previous development of high altitude balloon/high power rocket hybrid systems have been undertaken by government funded military programs or large aerospace corporations with varying degrees of success. However, there has yet to be a successful flight with this type of system which provides access to the upper mesosphere in a university setting. This project will aim to design and analyze a viable system while testing the engineering process under challenging budgetary constraints. The

    A failure recovery system utilizing a multi-core fiber (MCF) link with field programmable gate array-based optical switch units was developed to achieve high capacity and highly reliable optical networks in access areas. We describe the novel MCF link based on a multi-ring structure and a protection scheme to prevent link failures. Fan-in/ -out devices and connectors are also presented to demonstrate the development status of the MCF connection technology for the link. We demonstrated path recovery by switching operation within a sufficiently short time, which is required by ITU-T. The selection of a protecting path as a failure working path was also optimized as the minimum passage of units for low loss transmission. The results we obtained indicate that our proposed link has potential for the network design of highly reliable network topologies in access areas such as data centers, systems in business areas, and fiber to the home systems in residential areas.

    NASA's Atmospheric Science Data Center (ASDC) is utilizing Geographic Information System (GIS) technology that can increase data discoverability and accessibility of ASDC data to the GIS user community. Data products have had compatibility issues, limiting their use in open source as well as commercial tools, such as Esri's ArcGIS Platform. The ASDC is working in collaboration with ESDIS, Esri, The HDF Group, and George Mason University (GMU) to identify and address these compatibility issues. Once addressed, web services can be created on top of the data sets and accessed through desktop, mobile, and web based GIS tools. These services include the Open Geospatial Consortium (OGC) Web Mapping Service, OGC Web Coverage Service, and Image Service. Exposing services through desktop, mobile, and web based GIS tools is expected to yield a greater usage of NASA ASDC data as well as new analysis utilizing GIS tools for an increased understanding in the areas of the earth's radiation budget, clouds, aerosols, and tropospheric chemistry.

    Three-dimensional integration processes (based on direct wafer bonding and back-surface silicon removal) for magnetic tunnel junctions with perpendicular magnetization (p-MTJs) were developed. Perfect wafer bonding, namely, bonding without interfacial voids, and damageless silicon removal were successfully demonstrated by using very flat tantalum cap layers. Moreover, p-MTJ nanopillars subjected to these processes exhibited no degradation in magnetoresistance or spin-transfer-torque (STT) switching. Magnetoresistive random access memory (MRAM) technology incorporating these processes (direct wafer bonding and back-surface silicon removal) will make it possible to integrate epitaxial MTJs (with a single-crystal tunnel barrier) and ferromagnetic electrode layers (based on new materials).

  2. Current perspective regarding adults with intellectual and developmental disabilities accessing computer technology.

    PubMed

    Hoppestad, Brian Scott

    2013-05-01

    This article was written to summarize current efforts in the research community in regards to assisting adults with severe developmental and intellectual disabilities to access a computer. A literature search was conducted to determine contemporary research that has been conducted to enable computer use in persons with significant developmental disabilities utilizing databases such as ERIC or PubMed. Although various assistive technology devices and interventions have been developed for persons with all types of disabilities, a lack of research into methods to help persons with severe developmental disabilities access a computer is evident. This perpetuates the underutilization of computers in this population such as those attending day programs or residing in residential facilities. Persons with developmental disabilities, particularly adults, are often overlooked and are not thought to be capable of using a personal computer. Though communities have endeavored to further enhance participation by persons with disabilities in many aspects of mainstream society, there is a scarcity of research pertaining to how adults with intellectual disabilities can access a computer, especially those with severe impairments. Once formal schooling is over, there appears to be scant interest in supporting adults using computers.

    Biobanks represent key resources for clinico-genomic research and are needed to pave the way to personalised medicine. To achieve this goal, it is crucial that scientists can securely access and share high-quality biomaterial and related data. Therefore, there is a growing interest in integrating biobanks into larger biomedical information and communication technology (ICT) infrastructures. The European project p-medicine is currently building an innovative ICT infrastructure to meet this need. This platform provides tools and services for conducting research and clinical trials in personalised medicine. In this paper, we describe one of its main components, the biobank access framework p-BioSPRE (p-medicine Biospecimen Search and Project Request Engine). This generic framework enables and simplifies access to existing biobanks, but also to offer own biomaterial collections to research communities, and to manage biobank specimens and related clinical data over the ObTiMA Trial Biomaterial Manager. p-BioSPRE takes into consideration all relevant ethical and legal standards, e.g., safeguarding donors’ personal rights and enabling biobanks to keep control over the donated material and related data. The framework thus enables secure sharing of biomaterial within open and closed research communities, while flexibly integrating related clinical and omics data. Although the development of the framework is mainly driven by user scenarios from the cancer domain, in this case, acute lymphoblastic leukaemia and Wilms tumour, it can be extended to further disease entities.

  4. Fiber in access technologies and network convergence: an opportunity for optical integration

    2008-11-01

    Broadband networks are among the fastest growing segment in telecom. The initial and still very significant push originated with xDSL technologies and indeed a significant amount of research and development is still occurring in this field with impressive results and allowing for a remarkable use of the installed copper infrastructure way beyond its originally planned bandwidth capabilities. However it is clear that ultimately a more suitable fiber based infrastructure will be needed in order to reduce both operational and network technology costs. Such cost reduction in inevitable as the added value to end users is only related to services and these cannot be priced outside a sensible window, whilst the related bandwidth increase is much more dramatic and its huge variability must be met with little or no cost impact by the network and its operation. Fiber in access has indeed the potential to cope with a huge bandwidth demand for many years to come as its inherent bandwidth capabilities are only just tapped by current service requirements. However the whole technology supply chain must follow in line. In particular optical technology must brace itself to cope with the required much larger deployment and greater cost effectiveness, whilst at the same time deliver performance suitable to the bandwidth increase offered in the longer term by the fiber medium. This paper looks at this issues and debates the opportunities for a new class of optical devices making use of the progress in optical integration

  11. Establishing access to technology: an evaluation and intervention model to increase the participation of children with cerebral palsy.

    PubMed

    McCarty, Elizabeth; Morress, Claire

    2009-08-01

    Children with a diagnosis of cerebral palsy often have significant physical limitations that prevent exploration and full participation in the environment. Assistive technology systems can provide opportunities for children with physical limitations to interact with their world, enabling play, communication, and daily living skills. Efficient access to and control of the technology is critical for successful use; however, establishing consistent access is often difficult because of the nature of the movement patterns exhibited by children with cerebral palsy. This article describes a 3-phase model of evaluation and intervention developed and used by Assistive Technology Services at the Aaron W. Perlman Center, Cincinnati Children's Hospital Medical Center, to establish successful access to technology systems in children with cerebral palsy.

  12. The design of the multipurpose Lusi drone. When technology can access harsh environments.

    Extreme and inaccessible environments are a new frontier that unmanned and remotely operated vehicles can today safely access and monitor. The Lusi mud eruption (NE Java Island, Indonesia) represents one of these harsh environments that are totally unreachable with traditional techniques. Here boiling mud is constantly spewed tens of meters in height and tall gas clouds surround the 100 meters wide active crater. The crater is surrounded by a 600 meters circular zone of hot mud that prevents any approach to investigate and sample the eruption site. In the framework of the Lusi Lab project (ERC grant n° 308126) we assembled and designed a multipurpose drone to survey the eruption site. The Lusi drone is equipped with numerous airborne devices suitable for use on board of other multicopters. During the missions three cameras can complete 1) video survey, 2) high resolution photogrammetry of desired and preselected polygons, and 3) thermal photogrammetry surveys with infra-red camera to locate hot fluids seepage areas or faulted zones. Crater sampling and monitoring operations can be pre-planned with a flight software, and the pilot is required only for take-off and landing. An automatic winch allows the deployment of gas, mud and water samplers and contact thermometers to be operated with no risk for the aircraft. During the winch operations (that can be performed automatically) the aircraft hovers at a safety height until the tasks are completed while being controlled by the winch embedded processor. The drone is also equipped with a GPS connected CO2 and CH4 sensors. Gridded surveys using these devices allowed obtaining 2D maps of the concentration and distribution of various gasses over the area covered by the flight path.

    The Mexican Petroleum Institute (IMP) is a public facility oriented to research and technological development for the national petroleum industry. Its investment plan and operating expenses come, mainly, from selling engineering services to Petróleos Mexicanos. Its projects include upstream and downstream aspects, and the generated income together with public funds support research projects. These funds were approved since 2005, and widened in 2008 thanks to the so called Energy Reform. Until now, more than 50 projects have been funded, and this presentation shows the process to select, to approve, to fund and to ensure the results promised in the original proposal. It is shown that technical sanction of every particular project is essential to succeed, jointly with a structure of real technical pairs to advise during project development. Likewise, the mechanisms for accessing the funds are described, and simple suggestions are made to improve administrative efficiency.

    Linearized optical intensity modulator is recognized as one of the building blocks in any analog fiber-optics links systems such as subcarrier multiplexing (SCM) systems, ultra-dense CATV, Radio-over-Fiber (RoF) communications, and other platform access systems. For more than 30 years, the quest for highly linearized optical modulator with SFDR > 130 dB-Hz 2/3 represents a major, on-going technology goal. This invited paper has three-fold objective namely: (1) provide comprehensive overview of the numerous existing linearized optical intensity modulators, (2) introduce a classification of these linearized modulators, and (3) present recent development of new, super-linear (SFDR = 130-140 dB-Hz 2/3) modulator which the authors pioneered. Other features of this new modulator are simple setup, high tolerance and low-cost. Performance results are presented via numerical simulation, its potential applications and limitations are also discussed.

    2014-12-01

    A host of new services are revolutionizing discovery, visualization, and access of NASA's Earth science data holdings. At the same time, web browsers have become far more capable and open source libraries have grown to take advantage of these capabilities. Earthdata Search is a web application which combines modern browser features with the latest Earthdata services from NASA to produce a cutting-edge search and access client with features far beyond what was possible only a couple of years ago. Earthdata Search provides data discovery through the Common Metadata Repository (CMR), which provides a high-speed REST API for searching across hundreds of millions of data granules using temporal, spatial, and other constraints. It produces data visualizations by combining CMR data with Global Imagery Browse Services (GIBS) image tiles. Earthdata Search renders its visualizations using custom plugins built on Leaflet.js, a lightweight mobile-friendly open source web mapping library. The client further features an SVG-based interactive timeline view of search results. For data access, Earthdata Search provides easy temporal and spatial subsetting as well as format conversion by making use of OPeNDAP. While the client hopes to drive adoption of these services and standards, it provides fallback behavior for working with data that has not yet adopted them. This allows the client to remain on the cutting-edge of service offerings while still boasting a catalog containing thousands of data collections. In this session, we will walk through Earthdata Search and explain how it incorporates these new technologies and service offerings.

  1. Technologic advances and program initiatives in public access defibrillation using automated external defibrillators.

    PubMed

    White, R D

    2001-06-01

    Widespread provision of early defibrillation following cardiac arrest holds major promise for improved survival from ventricular fibrillation. The critical element in predicting a successful outcome is the rapidity with which defibrillation is achieved. A worldwide awareness of this potential and its advocacy by such organizations as the American Heart Association have been pivotal in the evolution of initiatives to make defibrillation more widely and more rapidly available. The feasibility of this initiative, known as public access defibrillation, is in large measure a direct consequence of major technologic advances in automated external defibrillators (AEDs). New low-energy waveforms with biphasic morphology have been shown to be more effective in terminating ventricular fibrillation and may do so with less myocardial injury. Placement of AEDs in a variety of nontraditional settings such as police cars, aircraft and airport terminals, and gambling casinos has been shown to yield an impressive number of survivors of cardiac arrest in ventricular fibrillation. Questions yet to be answered center on the appropriate disposition of AEDs in public access defibrillation settings, training and retraining issues, device maintenance, and collection of accurate data to document benefit and to identify areas of needed improvement or expansion of AED availability.

    To demonstrate the potential of GIS (geographic information system) technology and ARIA (Accessibility/Remoteness Index for Australia) as tools for medical workforce and health service planning in Australia. ARIA is an index of remoteness derived by measuring road distance between populated localities and service centres. A continuous variable of remoteness from 0 to 12 is generated for any location in Australia. We created a GIS, with data on location of general practitioner services in non-metropolitan South Australia derived from the database of RUMPS (Rural Undergraduate Medical Placement System), and estimated, for the 1170 populated localities in South Australia, the accessibility/inaccessibility of the 109 identified GP services. Distance from populated locality to GP services. Distance from populated locality to GP service ranged from 0 to 677 km (mean, 58 km). In all, 513 localities (43%) had a GP service within 20 km (for the majority this meant located within the town). However, for 173 populated localities (15%), the nearest GP service was more than 80 km away. There was a strong correlation between distance to GP service and ARIA value for each locality (0.69; P < 0.05). GP services are relatively inaccessible to many rural South Australian communities. There is potential for GIS and for ARIA to contribute to rational medical workforce and health service planning. Adding measures of health need and more detailed data on types and extent of GP services provided will allow more sophisticated planning.

In-situ sampling and distributed sensor networks, linked by an advanced cyberinfrastructure, will collect site-based data on a variety of organisms, soils, aquatic systems, atmosphere and climate. Targeted airborne remote sensing observations made by NEON as well as geographical data sets and satellite resources produced by Federal agencies will provide data at regional and national scales. The resulting data streams, collected over a 30-year period, will be synthesized into fully traceable information products that are freely and openly accessible to all users. We provide an overview of several collection, access and presentation technologies evaluated for use by observatory systems throughout the data product life cycle. Specifically, we discuss smart phone applications for citizen scientists as well as the use of handheld devices for sample collection and reporting from the field. Protocols for storing, queuing, and retrieving data from observatory sites located throughout the nation are highlighted as are the application of standards throughout the pipelined production of data products. We discuss the automated incorporation of provenance information and digital object identifiers for published data products. The use of widgets and personalized user portals for the discovery and dissemination of NEON data products are also presented.

    The impact of health technology assessment (HTA) in the judicialization of the right of health has not been deeply studied in Latin American countries. The purpose of this study is to review the process of judicialization of the access to high cost drugs in Uruguay and assess the impact HTAs have had on this process. The methodology used for this study included a comprehensive literature search in electronic databases, local journals, internal documents developed in the Ministry of Health, as well as conducting interviews with key informants. Judicialization of the access of high cost drugs has been increasing since 2010. The strategy of the Ministry of Health of Uruguay to decrease this problem included the organization of roundtables with judges and other stakeholders on the basis of HTA, the training of defense lawyers in the use and interpretation of HTA, and the participation of a professional who develops HTA in the preparation of the defense arguments. A year after the implementation of this strategy, 25 percent of writs of protection were won by the Ministry of Health. Even though the strategy implemented was effective in reducing the loss of litigations, it was not effective in reducing the growing number of writs of protection. It is essential to address this problem in a broad debate and to promote understanding between the parties.

    Many Americans have diets that do not meet the dietary guidelines set by the US Department of Agriculture (USDA). Additionally, low-income people have the highest rates of obesity and have difficulty accessing the necessary foods for maintaining a healthful diet. In December 2007 and January 2008, 21 retail food stores in Central Falls, Rhode Island, where residents were predominantly low-income Hispanics, were evaluated for the availability and costs of foods that fulfill the USDA's Thrifty Food Plan (TFP) guidelines. Each surveyed store was evaluated for variety and weekly cost of 3 different types of market baskets (2 families and an elder). Each store's proximity to public transportation was estimated by using geographic information systems mapping. Only 2 stores in Central Falls and the discount supermarket in an adjacent city, Pawtucket, carried enough variety of foods to fill the TFP basket. At the 2 stores, costs were up to 40% higher, and at the discount store, costs were up to 18% cheaper, than the national average. Each of the stores was accessible by public transportation. Meeting the USDA TFP guidelines is difficult in this low-income, predominantly Hispanic city. Although the components of the TFP are available, high prices may make a nutritious diet unaffordable.

    This case study describes how an individual with spastic quadriplegic cerebral palsy was trained over a period of four weeks to use a commercial electroencephalography (EEG)-based brain-computer interface (BCI). The participant spent three sessions exploring the system, and seven sessions playing a game focused on EEG feedback training of left and right arm motor imagery and a customised, training game paradigm was employed. The participant showed improvement in the production of two distinct EEG patterns. The participant's performance was influenced by motivation, fatigue and concentration. Six weeks post-training the participant could still control the BCI and used this to type a sentence using an augmentative and alternative communication application on a wirelessly linked device. The results from this case study highlight the importance of creating a dynamic, relevant and engaging training environment for BCIs. Implications for Rehabilitation Customising a training paradigm to suit the users' interests can influence adherence to assistive technology training. Mood, fatigue, physical illness and motivation influence the usability of a brain-computer interface. Commercial brain-computer interfaces, which require little set up time, may be used as access technology for individuals with severe disabilities.

    To examine how information and communication technology (ICT) access and use are conceptually incorporated in the Successful Aging 2.0 framework. Using data from the 2011 National Health and Aging Trends Study (N = 6,476), we examined how ICT access and use for different purposes are associated with social engagement (i.e., informal and formal social participation) by gender. Weighted logistic regression analyses were performed. Findings revealed that men were more likely to access and use ICT than women. ICT access was positively associated with all types of women's social engagement, but only with men's informal social participation. Information technology (IT) use for health matters was positively associated with formal social participation for women and with informal social participation for men. IT use for personal tasks was negatively associated with formal social participation for older adults. Communication technology use was positively associated with formal and informal social participation for women and men. This study supports the expansion of the successful aging model by incorporating ICT access and use. Further, it assists in the identification of specific technologies that promote active engagement in later life for women and men.

    This multimethod pilot study examined patient and practitioner perspectives on the influence of spatial barriers to healthcare access and the role of health information technology in overcoming these barriers. The study included a survey administered to patients attending a Department of Veterans Affairs (VA) health visit, and a focus group with VA care providers. Descriptive results and focus group findings are presented. Spatial distance is a significant factor for many rural veterans when seeking healthcare. For this sample of rural veterans, a range of telephone, computer, and Internet technologies may become more important for accessing care as Internet access becomes more ubiquitous and as younger veterans begin using the VA health system. The focus group highlighted the negative impact of distance, economic considerations, geographic barriers, and specific medical conditions on access to care. Lack of adequate technology infrastructure was seen as an obstacle to utilization. This study discusses the need to consider distance, travel modes, age, and information technology infrastructure and adoption when designing health information technology to care for rural patients.

    Assistive technologies (ATs) for computer access enable people with disabilities to be included in the information society. Current methods for assessment and selection of the most appropriate AT for each individual are non standardized, lengthy, subjective, and require substantial clinical experience of a multidisciplinary team.This manuscript presents and evaluates an objective approach to test and select an appropriate AT for computer access for people with disabilities. Six user interfaces(standard keyboard, mini and large joystick, mini and large trackball, and head-operated mouse and keyboard) were tested on the control group of 29 people without disabilities and on 63 people with neuromuscular and muscular diseases, using purpose-built software for testing the speed of sentence typing. Different criteria for selecting the optimal AT were tested and compared with the skilled clinician's choice. The learning curves of the people with disabilities proved to follow those of the healthy controls, but with lower performance. Daily computer use was not associated with AT selection, but corresponded nearly perfectly to the level of functional ability of upper limbs. Agreement between clinician's choice and learning-based AT selection was noteworthy,but far from perfect. If partial agreement was taken into account, that is, AT was considered as an ordinal variable based on the corresponding functional ability level, and the second best learning-based choice was taken into account,the agreement was high for highest median typing speed as AT selection criterion. In conclusion, the developed method for AT assessment and selection seems to be an efficient guide for an unskilled clinician to choose an appropriate AT.

    The Akamai Workforce Initiative (AWI) is an interdisciplinary effort to improve science/engineering education in the state of Hawai'i, and to train a diverse population of local students in the skills needed for a high-tech economy. In 2009, the AWI undertook a survey of industry partners on Maui and the Big Island of Hawai'i to develop an engineering technology skills framework that will guide curriculum development at the U. of Hawai'i - Maui (formerly Maui Community College). This engineering skills framework builds directly on past engineering-education developments within the Center for Adaptive Optics Professional Development Program, and draws on curriculum development frameworks and engineering skills standards from the literature. Coupling that previous work with reviews of past Akamai Internship projects and information from previous conversations with the local high-tech community led to a structured-interview format where engineers and managers could contribute meaningful commentary to this framework. By incorporating these local high-tech companies' needs for entry-level engineers and technicians, a skills framework emerges that is unique and illuminating. Two surprising features arise in this framework: (1) "technician-like" skills of making existing technology work are on similar footing with "engineer-like" skills of creating new technology; in fact, both engineers and technicians at these workplaces use both sets of skills; and (2) project management skills are emphasized by employers even for entry-level positions.

    This paper surveys and describes some of the existing media access control and data link layer technologies for possible application in lunar surface communications and the advanced wideband Direct Sequence Code Division Multiple Access (DSCDMA) conceptual systems utilizing phased-array technology that will evolve in the next decade. Time Domain Multiple Access (TDMA) and Code Division Multiple Access (CDMA) are standard Media Access Control (MAC) techniques that can be incorporated into lunar surface communications architectures. Another novel hybrid technique that is recently being developed for use with smart antenna technology combines the advantages of CDMA with those of TDMA. The relatively new and sundry wireless LAN data link layer protocols that are continually under development offer distinct advantages for lunar surface applications over the legacy protocols which are not wireless. Also several communication transport and routing protocols can be chosen with characteristics commensurate with smart antenna systems to provide spacecraft communications for links exhibiting high capacity on the surface of the Moon. The proper choices depend on the specific communication requirements.

    1993-01-01

    Intelligent computer aided training systems hold great promise for the application of this technology to mainstream education and training. Yet, this technology, which holds such a vast potential impact for the future of education and training, has had little impact beyond the enclaves of government research labs. This is largely due to the inaccessibility of the technology to those individuals in whose hands it can have the greatest impact, teachers and educators. Simply throwing technology at an educator and expecting them to use it as an effective tool is not the answer. This paper provides a background into the use of technology as a training tool. MindLink, developed by HyperTech Systems, provides trainers with a powerful rule-based tool that can be integrated directly into a Windows application. By embedding expert systems technology it becomes more accessible and easier to master.

  17. Early Patient Access to Medicines: Health Technology Assessment Bodies Need to Catch Up with New Marketing Authorization Methods.

    PubMed

    Leyens, Lada; Brand, Angela

    National and international medicines agencies have developed innovative methods to expedite promising new medicines to the market and facilitate early patient access. Some of these approval pathways are the conditional approval and the adaptive pathways by the European Medicines Agency (EMA); the Promising Innovative Medicine (PIM) designation and the Early Access to Medicines Scheme (EAMS) by the Medicines and Healthcare Products Regulatory Agency (MHRA), as well as the Fast Track, Breakthrough or Accelerated Approval methods by the Food and Drug Administration (FDA). However, at least in Europe, these methods cannot achieve the goal of improving timely access for patients to new medicines on their own; the reimbursement process also has to become adaptive and flexible. In the past 2 years, the effective access (national patient access) to newly approved oncology drugs ranged from 1 to 30 months, with an extremely high variability between European countries. The goal of early patient access in Europe can only be achieved if the national health technology assessment bodies, such as NICE (ENG), HAS (FR), G-BA (DE) or AIFA (IT), provide harmonized, transparent, flexible, conditional and adaptive methods that adopt the level of evidence accepted by the medicines agencies. The efforts from medicines agencies are welcome but will be in vain if health technology assessments do not follow with similar initiatives, and the European 'postcode' lottery will continue.

    This special issue addresses access to and service delivery of assistive technology (AT) in resource-limited environments (RLEs). Access to AT is complicated not simply by limited funds to purchase AT, but by larger ecosystem weaknesses in RLEs related to legislation and policy, supply, distribution, human resources, consumer demand and accessible design. We present eight diverse articles that address various aspects of the AT ecosystem. These articles represent a wide range of AT, many different countries and different research methods. Our goal is to highlight a topic that has received scant research investigation and limited investment in international development efforts, and offer an insight into how different countries and programs are promoting access to AT. We encourage researchers, funders and non-profit organizations to invest additional effort and resources in this area.

    A full logic-compatible embedded gate contact resistive random access memory (GC-RRAM) cell in the CMOS FinFET logic process without extra mask or processing steps has been successfully demonstrated for high-density and low-cost logic nonvolatile memory (NVM) applications. This novel GC-RRAM cell is composed of a transition metal oxide from the gate contact plug and interlayer dielectric (ILD) in the middle, and a gate contact and an n-type epitaxial drain terminal as the top and bottom electrodes, respectively. It features low-voltage operation and reset current, compact cell size, and a stable read window. As a promising embedded NVM solution, the compact one transistor and one resistor (1T1R) cell is highly scalable as the technology node progresses. Excellent data retention and cycling capability have also been demonstrated by the reliability testing results. These superior characteristics make GC-RRAM one of a few viable candidates for logic NVM for future FinFET circuits.

  15. Fertility tourism: circumventive routes that enable access to reproductive technologies and substances.

    PubMed

    Bergmann, Sven

    2011-01-01

    “Fertility tourism” is a journalistic eye‐catcher focusing on the phenomenon of patients who search for a reproductive treatment in another country in order to circumvent laws, access restrictions, or waiting lists in their home country. In Europe, the reasons why people seek reproductive treatments outside their national boundaries are quite diverse, in part because regulations differ so much among countries. Beginning with four examples of people who crossed borders for an in vitro fertilization (IVF) treatment with gamete donation, this article provides some insight into these transnational circumvention practices based on material from ethnographic fieldwork and interviews in Spain, Denmark, and the Czech Republic. In all three countries, gamete donation is made strictly anonymous. Clinical practices such as egg donor recruitment and phenotypical matching between donors and recipients serve to naturalize the substitution of gametes and to install social legitimacy through resemblance markers with the prospective child. In comparison to other areas of medical tourism, which are subjects of debate as a consequence of neoliberal health politics and international medical competition, mobility in the area of reproductive technologies is deeply intertwined with new forms of doing kinship. For prospective parents, it holds a promise of generating offspring who could pass as biogenetically conceived children. Therefore, IVF with gamete donation is mostly modeled after conceptions of nature. Through anonymity and concealment it creates forms of nonrelatedness that leave space for future imaginings and traces of transnational genetic creators.

    To develop and validate a patient-reported measure of access to information and technology (AIT) for persons with spinal cord injury, stroke, or traumatic brain injury. A mixed-methods approach was used to develop items, refine them through cognitive interviews, and evaluate their psychometric properties. Item responses were evaluated with the Rasch rating scale model. Correlational and analysis-of-variance methods were used to evaluate construct validity. Community-dwelling individuals participated in telephone interviews or traveled to the academic medical centers where this research took place. Individuals with a diagnosis of spinal cord injury, stroke, or traumatic brain injury (aged ≥18y, English speaking) participated in cognitive interviews (n=12 persons), field testing of the items (n=305 persons), and validation testing of the final set of items (n=604 persons). Not applicable. A set of items to measure AIT for people with disabilities. A user-friendly multimedia touchscreen was used for self-administration of the items. A 23-item AIT measure demonstrated good evidence of internal consistency reliability, and content and construct validity. This new AIT measure will enable researchers and clinicians to determine to what extent environmental factors influence health outcomes and social participation in people with disabilities. The AIT measure could also provide disability advocates with more specific and detailed information about environmental factors to lobby for elimination of barriers.

    Richardson, B.B.

    1984-01-01

    Until recently the sociological study of man environment relations under extreme circumstances has been restricted to natural hazards (e.g., floods, hurricanes, tornadoes). Technological disasters are becoming more commonplace (e.g., Times Beach, MO, Love Canal, TMI-2) and are growing as potential sources of impact upon human populations. However, theory regarding the social impact of such disasters has not been developed. While research on natural disasters is in part applicable to technological disasters, theory adapted from environmental sociology and psychology are also utilized to develop a theory of social response to extreme environmental events produced by technology. Hypotheses are developed in the form of an empirically testable model based on the literature reviewed.

    With the social networking and network socialisation have brought more text information and social relationships into our daily lives, the question of whether big data can be fully used to study the phenomenon and discipline of natural sciences has prompted many specialists and scholars to innovate their research. Though politics were integrally involved in the hyperlinked word issues since 1990s, automatic assembly of different geospatial web and distributed geospatial information systems utilizing service chaining have explored and built recently, the information collection and data visualisation of geo-events have always faced the bottleneck of traditional manual analysis because of the sensibility, complexity, relativity, timeliness and unexpected characteristics of political events. Based on the framework of Heritrix and the analysis of web-based text, word frequency, sentiment tendency and dissemination path of the Huangyan Island incident is studied here by combining web crawler technology and the text analysis method. The results indicate that tag cloud, frequency map, attitudes pie, individual mention ratios and dissemination flow graph based on the data collection and processing not only highlight the subject and theme vocabularies of related topics but also certain issues and problems behind it. Being able to express the time-space relationship of text information and to disseminate the information regarding geo-events, the text analysis of network information based on focused web crawler technology can be a tool for understanding the formation and diffusion of web-based public opinions in political events.

    The digital revolution is changing the manner in which patients communicate with their health care providers, yet many patients still lack access to communication technology. We conducted this study to evaluate access to, use of, and preferences for using communication technology among a predominantly low-income patient population. We determined whether access, use, and preferences were associated with type of health insurance, sex, age, and ethnicity. In 2011, medical student researchers administered questionnaires to patients of randomly selected physicians within 9 primary care clinics in the Residency Research Network of Texas. Surveys addressed access to and use of cell phones and home computers and preferences for communicating with health care providers. In this sample of 533 patients (77% response rate), 448 (84%) owned a cell phone and 325 (62%) owned computers. Only 48% reported conducting Internet searches, sending and receiving E-mails, and looking up health information on the Internet. Older individuals, those in government sponsored insurance programs, and individuals from racial/ethnic minority groups had the lowest levels of technology adoption. In addition, more than 60% of patients preferred not to send and receive health information over the Internet, by instant messaging, or by text messaging. Many patients in this sample did not seek health information electronically nor did they want to communicate electronically with their physicians. This finding raises concerns about the vision of the patient-centered medical home to enhance the doctor-patient relationship through communication technology. Our patients represent some of the more vulnerable populations in the United States and, as such, deserve attention from health care policymakers who are promoting widespread use of communication technology.

  3. Residential accessibility to information technology retailers and self reported computer use among patients attending community clinics

    The actual mechanisms that maintain the individual disparities in home computer use and internet access that are collectively termed “the digital divide” remain unclear. We hypothesized that geographic accessibility to IT retailers would independently influence community clinic patients self reported use of computers at home thus limiting their ability to access health related information via the internet. To test this we obtained information on the locations of IT retailers in Los Angeles County, California and generated accessibility scores for the patient’s home residence. Geographic measures of accessibility to IT retailers independently predicted clinic patient’s self reported use of computers at home, and this effect was driven by low income individuals. Our results indicate that the causes of the digital divide are influenced by less commonly considered factors such as local IT retailer availability. PMID:20351914

    Computer technology is used in various ways to deliver and enhance health care. It is therefore important to understand technology use patterns among underserved populations such as persons with serious mental illnesses who often experience inequitable care. A survey was administered to 210 veterans with serious mental illnesses attending programs at a Department of Veterans Affairs community care center, with data collected on demographics, psychiatric diagnoses, access, use, and willingness to use cell phones, smart phones, Internet-based online social networking, and computerized therapies. Descriptive and multivariable analyses were conducted to determine utilization and interest in different technologies. Although 80.4% of the respondents reported owning a cellphone, only 30.3% reported they had a computer and 13.1% reported owning a smartphone. Although 56.7% reported using the Internet and 47.6% indicated they used e-mail, 68.6% of respondents reported that they were interested in using computer programs for mental health-related problems. Older, less educated veterans, and those with alcohol use disorders were less likely to use the Internet. Veterans who were White or had PTSD diagnoses were less willing to use any computerized therapy. Lower rates of computer use, Internet, and cell phone technologies were observed among veterans with serious mental illnesses compared to general population surveys. Sociodemographic barriers likely impede access to technology among veterans with serious mental illnesses. Providing financial resources and associated education and training to veterans with serious mental illnesses could increase access to helpful technology-based interventions in a population that traditionally experiences service gaps.

    This paper examines how pregnant women living in South Australia use information and communication technologies (ICTs), principally Internet and mobile phones, to access pregnancy-related information. It draws on 35 semistructured interviews conducted as part of the 'Health-e Baby' project, a qualitative study designed to assess the information needs and ICT preferences of pregnant women cared for at a South Australian metropolitan teaching hospital. Our research shows that although ICTs offer exciting possibilities for health promotion and the potential for new forms of communication, networking and connection, we cannot assume the effectiveness of communicating through such channels, despite near universal levels of ICT access. In turn, this highlights that if e-mediated health promotion is to be effective, health promoters and practitioners need to better understand ICT access, usage and content preferences of their clients.

    We assessed the access, use and preferences of information and communication technology (ICT) by physicians who practice at Cayetano Heredia National Hospital. The questionnaire explored the availability and skills of ICT, time, educational activities, search engines and technological applications most used as well as ICT preferences in education.211 physicians were surveyed; laptop use was 93%, tablet and smartphone use was 66% and 88%.68% have mobile Internet. Differences were evident in the frequency of use of ICT in 25-34 year old age group as well as a higher level of skills (p<0.05). 86% use PubMed, Facebook and WhatsApp as a means of exchanging images and data related to health, 50% participated in medical blogs, online courses or videoconferences. The use and access of ICT is common among doctors in this hospital and there is positive interest in its use in education.

    The accessibility of cellulase and xylanase enzymes to glucan and xylan, respectively, and its change with conversion were measured for pure Avicel glucan and poplar solids that had been pretreated by ammonia fiber expansion (AFEX), ammonia recycled percolation (ARP), dilute acid, and lime. Avicel and pretreated solids were digested to various degrees by cellulase together with beta-glucosidase enzymes and then cleaned of residual protein via a biological method using Protease. Glucan accessibility was determined by purified CBHI (Cel7A) adsorption at 4 degrees C, and 4 and 24 h hydrolysis yields were determined for solids loading containing equal amounts of glucan (1.0% w/v) and lignin (1.0% w/v), in two separate sets of experiments. Consistent with our previous study and in contrast to some in the literature, little change in glucan accessibility was observed with conversion for Avicel, but glucan and xylan accessibility for real biomass varied with the type of pretreatment. For example, AFEX pretreated solids showed a negligible change in glucan accessibility for conversion up to 90%, although xylan accessibility seemed to decline first and then remained constant. On the other hand, a substantial decline in glucan and xylan accessibility with conversion was observed for lime pretreated poplar solids, as shown by initial hydrolysis rates. Yet, an increase in CBHI adsorption with conversion for lime pretreated poplar solids suggested the opposite trend, possibly due to increased lignin exposure and/or reduced effectiveness of adsorbed enzyme.

    STS072-732-072 (11-20 Jan. 1996) --- Three of the nineteen Galapagos Islands are visible in this image, photographed from the Earth-orbiting Space Shuttle Endeavour. The Galapagos Islands are located 600 miles (1,000 kilometers) to the west of Ecuador. The largest of the islands, Isabela, is at center (north is toward the upper right corner). The numerous circular features on the island, highlighted by clouds, are volcanoes. The Galapagos Islands owe their existence to a hot spot, or persistent heat source in the mantle, which also is located over a rift, or place where plates are separating and new crust is being created. The rift is located between the Cocos and Nazca Plates. The dark linear features on the islands are lava flows from past eruptions. The island to the left of Isabela is Fernandina, while the island to the right is San Salvador. The Galapagos Islands were visited by the English naturalist Charles Darwin in 1835.

    Background Many state and local health departments, as well as community organizations, have been using new technologies to disseminate health information to targeted populations. Yet little data exist that show access and use patterns, as well as preferences for receiving health information, at the state level. Objective This study was designed to obtain information about media and technology use, and health information seeking patterns, from a sample of New York State (NYS) residents. Methods A cross-sectional telephone survey (with mobile phones and landlines) was developed to assess media and technology access, use patterns, and preferences for receiving health information among a sample of 1350 residents in NYS. The survey used random digit dialing methodology. A weighted analysis was conducted utilizing Stata/SE software. Results Data suggest that NYS residents have a high level of computer and Internet use; 82% have at least one working computer at home, and 85% use the Internet at least sometimes. Mobile phone use is also high; 90% indicated having a mobile phone, and of those 63% have a smartphone. When asked about preferences for receiving health information from an organization, many people preferred websites (49%); preferences for other sources varied by demographic characteristics. Conclusions Findings suggest that the Internet and other technologies are viable ways to reach NYS residents, but agencies and organizations should still consider using traditional methods of communication in some cases, and determine appropriate channels based on the population of interest.

    Fifth-generation (5G) wireless access network promises to support higher access data rate with more than 1,000 times capacity with respect to current long-term evolution (LTE) systems. New radio-access-technologies (RATs) based on higher carrier frequencies to millimeter-wave (MMW) radio-over-fiber, and carrier-aggregation (CA) using multi-band resources are intensively studied to support the high data rate access and effectively use of frequency resources in heterogeneous mobile network (Het-Net). In this paper, we investigate several enabling technologies for MMW RoF systems in 5G Het-Net. Efficient mobile fronthaul (MFH) solutions for 5G centralized radio access network (C-RAN) and beyond are proposed, analyzed and experimentally demonstrated based on the analog scheme. Digital predistortion based on memory polynomial for analog MFH linearization are presented with improved EVM performances and receiver sensitivity. We also propose and experimentally demonstrate a novel inter-/intra- RAT CA scheme for 5G Het- Net. The real-time standard 4G-LTE signal is carrier-aggregated with three broadband 60GHz MMW signals based on proposed optical-domain band-mapping method. RATs based on new waveforms have also been studied here to achieve higher spectral-efficiency (SE) in asynchronous environments. Full-duplex asynchronous quasi-gapless carrier aggregation scheme for MMW ROF inter-/intra-RAT based on the FBMC is also presented with 4G-LTE signals. Compared with OFDM-based signals with large guard-bands, FBMC achieves higher spectral-efficiency with better EVM performance at less received power and smaller guard-bands.

    2010-01-01

    Abstract Objectives: Patients in underdeveloped countries may be left behind by advances in telehealthcare. We surveyed chronically ill patients with low incomes in Honduras to measure their use of mobile technologies and willingness to participate in mobile disease management support. Materials and Methods: 624 chronically ill primary care patients in Honduras were surveyed. We examined variation in telephone access across groups defined by patients' sociodemographic characteristics, diagnoses, and access to care. Logistic regression was used to identify independent correlates of patients' interest in automated telephonic support for disease management. Results: Participants had limited education (mean 4.8 years), and 65% were unemployed. Eighty-four percent had telephone access, and 78% had cell phones. Most respondents had voicemail (61%) and text messaging (58%). Mobile technologies were particularly common among patients who had to forego clinic visits and medications due to cost concerns (each p < 0.05). Most patients (>80%) reported that they would be willing to receive automated calls focused on appointment reminders, medication adherence, health status monitoring, and self-care education. Patients were more likely to be willing to participate in automated telemedicine services if they had to cancel a clinic appointment due to transportation problems or forego medication due to cost pressures. Conclusions: Even in this poor region of Honduras, most chronically ill patients have access to mobile technology, and most are willing to participate in automated telephone disease management support. Given barriers to in-person care, new models of mobile healthcare should be developed for chronically ill patients in developing countries. PMID:21062234

    This paper describes the status quo of the power sector in Burkina Faso, its limitations, and develops a new methodology that through spatial analysis processes with the aim to provide a possible pathway for universal electricity access. Following the SE4All initiative approach, it recommends the more extensive use of distributed renewable energy systems to increase access to electricity on an accelerated timeline. Less than 5% of the rural population in Burkina Faso have currently access to electricity and supply is lacking at many social structures such as schools and hospitals. Energy access achievements in Burkina Faso are still very modest. According to the latest SE4All Global Tracking Framework (2015), the access to electricity annual growth rate in Burkina Faso from 2010 to 2012 is 0%. The rural electrification strategy for Burkina Faso is scattered in several electricity sector development policies: there is a need of defining a concrete action plan. Planning and coordination between grid extension and the off-grid electrification programme is essential to reach a long-term sustainable energy model and prevent high avoidable infrastructure investments. This paper goes into details on the methodology and findings of the developed Geographic Information Systems tool. The aim of the dynamic planning tool is to provide support to the national government and development partners to define an alternative electrification plan. Burkina Faso proves to be paradigm case for the methodology as its national policy for electrification is still dominated by grid extension and the government subsidising fossil fuel electricity production. However, the results of our analysis suggest that the current grid extension is becoming inefficient and unsustainable in order to reach the national energy access targets. The results also suggest that Burkina Faso’s rural electrification strategy should be driven local renewable resources to power distributed mini-grids. We find that

    Nurses are exposed to the changing demands in technology as they execute their patient-related duties in the workplace. Integration of Information Technology (IT) in healthcare systems improves the quality of care provided. Nursing students with prior exposure to computers tend to have a positive influence IT. A descriptive study design using a quantitative approach and structured questionnaire was used to measure the nurses' attitudes towards computer usage. A census of 45 post-basic first year nursing management students were participated in this study. The students demonstrated a positive attitude towards the use of a computer. But access to and use of a computer and IT was limited and nurses in clinics had no access to IT. A lack of computer skills was identified as a factor that hinders access to IT. Nursing students agreed that computer literacy should be included in the curriculum to allow them to become independent computer users. The Department of Health should have IT in all health-care facilities and also train all health-care workers to use IT. With the positive attitudes expressed by the students, nurse managers need to create a conducive environment to ensure such a positive attitude continues to excel. © 2011 Blackwell Publishing Ltd.

    People with a disability do not have equitable access to the modern telecommunication medium. Many experience difficulty typing, handling the phone, dialling or answering calls. For those who are unable to speak, the only option is to type messages using whatever functional control site exists on their body. The provision of accessible mobile phones for people with disabilities can significantly improve their quality of life through an increased range of accessible activities, and can improve their independence, safety, security and self-esteem. This research was aimed at providing practical ways for people with a disability to participate in the extensive community of home and mobile phone users. The outcomes of ten participants taking part in the evaluation and trial of off-the-shelf telecommunication options are presented. Nine out of ten participants showed high to very high results in terms of their overall performance and satisfaction with the use of the telecommunication equipment provided. With the right policies, processes and support through equipment matching, education, training and delivery, current off-the-shelf solutions can help people with disabilities to effectively communicate with other members of our society and to access the same range of information systems and services enjoyed by able-bodied members of the community.

    2011-12-01

    Shortening the cycle from data collection to research publications is a competitive advantage for researchers. Existing technologies for inventory systems such as UPC barcoding systems can be coupled with flexible mobile or handheld devices to advance efficiency, productivity, automation, and integrity in data flows, from data collection to sample processing to database management and analysis, and finally publication. At the University of Texas, the Data Flow Infrastructure Initiative (DFII) has introduced handheld devices with integrated barcode scanners as a mechanism to enhance research productivity and information access. These devices are established technology and provide a flexible but consistent platform for research data collection and data management. They are not in widespread use yet in the research community. Additional application benefits will accrue by using handheld devices to deliver data on demand in teaching applications. Introducing research scientists, graduate students, and the UT community to the merits and flexibility of these data collection technologies will provide avenues for innovation as well as improving efficiency. The objective of this project is to bring the technology and expertise with handheld systems to a diverse set of pilot projects and establish proficiency at The University of Texas at Austin necessary for widespread application. We have implemented a pilot project in three research labs covering the fields of microbial ecology, water resources decision support, and biogeochemistry to introduce these technologies. We used NautizX5 handheld devices that feature: barcode scanning, bluetooth, stylus, and keypad data inputs coupled with Pendragon Forms Software, a program that allows users to create custom data collection forms structured into an SQL or Access platform thus allowing concurrent data management, data collection and analysis in field and lab settings. Results include the elimination of most manual data entry

  17. Learning and mastery behaviours as risk factors to abandonment in a paediatric user of advanced single-switch access technology.

    2013-09-01

    The present descriptive case study documents the behaviours of a child single-switch user in the community setting and draws attention to learning and mastery behaviours as risk factors to single-switch abandonment. Our observations were interpreted in the context of a longer term school-based evaluation of an advanced single-switch access technology with a nine year-old user with severe spastic quadriplegic cerebral palsy. The child completed 25 experiment sessions averaging a rate of three sessions every two weeks. During each session he worked on several blocks of single-switch computer activity using his vocal cord vibration switch. Despite high levels of single-switch sensitivity and specificity that suggested a good fit between the participant and the technology, the participant perceived a lower proficiency level of his own abilities, demonstrated impatience and intolerance to interaction errors, and was apprehensive of making mistakes when using his switch in public. The benefit of gaining some degree of independent physical access might not necessarily enhance resilience to interaction errors or bouts of poor task performance. On the other hand, the participant's behaviours were consistent with those of a typically developing child learning or mastering any new skill or task. Implications for Rehabilitation The attitude and behaviour of a paediatric switch user towards skill development can be risk factors to abandonment of an access technology, despite successful clinical trial with the device. Children with severe disabilities can be associated with the same types of skill development behaviour patterns and achievement motivation as their typically developing peers. Empirical observations of the case participant's switch use behaviours suggest that user training could be adaptive in order to account for individual differences in skill development and achievement motivation.

    Hydroxyurea is the only Food and Drug Administration approved medication for sickle cell disease (SCD) with short- and long-term benefits for both morbidity and mortality. However, hydroxyurea underutilization and adherence remain challenges for patients with SCD. The objectives of this study were to determine access to technology among adolescents and young adults (AYA) with SCD and to identify their preferred technology-based strategies for improving medication adherence. A cross-sectional survey was administered in a variety of clinical settings from October 2014 through May 2015 to AYA (12-22 years) with SCD (all genotypes) followed in a Comprehensive Sickle Cell Program. Eighty of 107 eligible participants completed the survey for a 75% response rate. Participants (51% female, 94% Black) had a mean age of 15.3 ± 2.8 years. Most participants (75%) were on a daily medication with about half on hydroxyurea. Forgetfulness (67%) was the most common barrier to medication adherence. The majority of participants (85%) owned smartphones and either owned or had access to electronic tablets (83%), laptops (72%), or desktops (70%). Of the proposed smartphone app features, daily medication reminders were ranked first most frequently, followed by education about SCD, adherence text prompts, education about SCD medications, and medication log. The majority of our AYA with SCD owned smartphones and had access to other electronic devices. Our survey results provided valuable insight into the preferred app features and optimal strategies for developing technology-based interventions, such as a multicomponent app, to increase medication adherence for AYA with SCD or other chronic conditions. © 2016 Wiley Periodicals, Inc.

    Ensuring quality of data during electronic data capture has been one of the most neglected components of operational research. Multicentre studies are also challenged with issues about logistics of travel, training, supervision, monitoring and troubleshooting support. Allocating resources to these issues can pose a significant bottleneck for operational research in resource-limited settings. In this article, we describe an innovative and efficient way of coordinating data capture in multicentre operational research using a combination of three open access technologies-EpiData for data capture, Dropbox for sharing files and TeamViewer for providing remote support.

    2015-03-01

    Mobile technology presents new opportunities for nursing education and ultimately the provision of nursing care. The aim of this study was to explore the utility of mobile technology in undergraduate nursing education. In this evaluation study, undergraduate nursing students were provided with iPod Touch devices containing best practice guidelines. Computer self-efficacy was assessed, and the Theory of Planned Behavior was used to identify potential predictors of the use of mobile technology. Questionnaires were completed at baseline (n = 33) and postimplementation (n = 23). Feedback on feasibility issues was recorded throughout the study period. Students generally found the devices useful, and few technical problems were identified; however, lack of skill in using the devices and lack of support from staff in the clinical setting were commonly identified issues. Self-efficacy scores were high throughout the study. Attitudes, perceptions of the desirability of use, perceived personal control over use, and intentions of using the device were lower postimplementation than at baseline. Attitude toward the technology predicted intention to use the device after graduation. Mobile technology may promote evidence-informed practice; however, supporting students' acquisition of related skills may optimize use. Successful integration of mobile technology into practice requires attention to factors that affect student attitudes.

  1. Access to hospitals with high-technology cardiac services: how is race important?

    Blustein, J; Weitzman, B C

    1995-01-01

    OBJECTIVES. Relatively few hospitals in the United States offer high-technology cardiac services (cardiac catheterization, bypass surgery, or angioplasty). This study examined the association between race and admission to a hospital offering those services. METHODS. Records of 11,410 patients admitted with acute myocardial infarction to hospitals in New York State in 1986 were analyzed. RESULTS. Approximately one third of both White and Black patients presented to hospitals offering high-technology cardiac services. However, in a multivariate model adjusting for home-to-hospital distance, the White-to-Black odds ratio for likelihood of presentation to such a hospital was 1.68 (95% confidence interval = 1.42, 1.98). This discrepancy between the observed and "distance-adjusted" probabilities reflected three phenomena: (1) patients presented to nearby hospitals; (2) Blacks were more likely to live near high-technology hospitals; and (3) there were racial differences in travel patterns. For example, when the nearest hospitals did not include a high-technology hospital, Whites were more likely than Blacks to travel beyond those nearest hospitals to a high-technology hospital. CONCLUSIONS. Whites and Blacks present equally to hospitals offering high-technology cardiac services at the time of acute myocardial infarction. However, there are important underlying racial differences in geographic proximity and tendencies to travel to those hospitals. PMID:7892917

    2015-02-01

    The efficient and unbundled use of the existing telecommunications infrastructure represents a major goal for the development of the services offered by telecommunications providers. A major telecommunications operator can provide services to a subscriber using a copper wire pair or part of the frequency spectrum of a copper wire pair, together with other operators, through a process of unbundling access in the local loop. Since access to the vocal band is an already solved problem, concerns turn to the broadband access with xDSL service delivery on ungrouped subscriber loops; besides the legal and economic aspects involved this has become an engineering problem also. The local loop unbundling methods have a substantial technical impact. This impact should be taken into account right from the design stage and then in the standardization stage of broadband systems intended to operate on copper wire pairs in the local loop. These systems are known under the generic term of xDSL and began to be analyzed in the late 90s. xDSL became the dominant solution for providing Internet at a reasonable price for both residential and business subscribers. In this massive development scenario, certain problems will arise from the early stages of deployment, and another type of problems will occur later on when a large number of systems will be installed in a single beam.

    The pharmacy profession has long used technology to more effectively bring health care to the patient. Navy pharmacy has embraced technology advances in its daily operations, from computers to dispensing robots. Evolving from the traditional role of compounding and dispensing specialists, pharmacists are establishing themselves as vital team members in direct patient care: on the ward, in ambulatory clinics, in specialty clinics, and in other specialty patient care programs (e.g., smoking cessation). An important part of the evolution is the timely access to the most up-to-date information available. Micromedex, Inc. (Denver, Colorado), has developed a number of computer CD-ROM-based full-text pharmacy, toxicology, emergency medicine, and patient education products. Micromedex is a recognized leader with regard to total pharmaceutical information availability. This article discusses the implementation of Micromedex products within the established Composite Healthcare Computer System and the subsequent use by and effect on the international Navy pharmacy community.

    Background: In Brazil, access to infertility care, including assisted reproductive technologies (ARTs), is restricted. This is the third report of a study on access to infertility care and ARTs within the public sector, focusing on the barriers to these services. Methods: The study was anchored on quantitative and qualitative methods. For the quantitative study interviews were conducted with health authorities in each of the 26 states, the Federal District, the state capitals and 16 cities with ≥ 500,000 inhabitants and directors of infertility referral centres within the public sector. Qualitative case studies were conducted in five ART centres. Results: Overall, 63.5% of the authorities reported that complex infertility treatments were unavailable. Barriers identified consisted of “lack of political decision to implement them”, and “lack of financial resources”. In addition, 75% reported to have “no plans to implement them over the next 12 months”. At the facilities offering ART, the barriers to these procedures were the high costs, long waiting times, complex scheduling processes and lack of initiative to implement low cost ARTs. Conclusions: Infertile couples’ access to ART procedures is restricted due to the insufficient services and lack of political commitment to support existing and new services.. PMID:24753912

    Effective public health practice relies on the availability of public health data sources and assessment tools to convey information to investigators, practitioners, policy makers, and the general public. Emerging communication technologies on the Internet can deliver all components of the "who, what, when, and where" quartet more quickly than ever with a potentially higher level of quality and assurance, using new analysis and visualization tools. Open-source software provides the opportunity to build low-cost information systems allowing health departments with modest resources access to modern data analysis and visualization tools. In this paper, we integrate open-source technologies and public health data to create a web information system which is accessible to a wide audience through the Internet. Our web application, "EpiVue," was tested using two public health datasets from the Washington State Cancer Registry and Washington State Center for Health Statistics. A third dataset shows the extensibility and scalability of EpiVue in displaying gender-based longevity statistics over a twenty-year interval for 3,143 United States counties. In addition to providing an integrated visualization framework, EpiVue's highly interactive web environment empowers users by allowing them to upload their own geospatial public health data in either comma-separated text files or MS Excel spreadsheet files and visualize the geospatial datasets with Google Maps.

    The first of these two studies extended preliminary evidence on the use of technology-based programs for enabling students with severe and profound multiple disabilities to choose and access environmental stimuli on their own. Each of the three participants had two microswitches linked to specific sets of stimuli through a computer system. The activation of one of the microswitches triggered the computer system to present a sample of one of the stimuli. If the student chose it, the computer system turned it on for a specific time interval. The second study tested a new technology that allowed the students to choose and access the chosen stimuli with the involvement of the caregiver. The two participants had three microswitches linked to a computer system. The participants' choice of a stimulus alerted the caregiver who then got involved in the stimulation process. The results of both studies showed that the participants learned to activate the basic microswitches consistently, had high percentages of choice for the stimulus samples presented by the computer but with wide differences across stimuli, and largely maintained this performance at a 2-month post-intervention check. These findings were analyzed in terms of the usability of the two types of programs, the role they may play within educational and living contexts, and their innovative technical dimensions.

    A variety of technology-aided programs have been developed to help persons with congenital or acquired multiple disabilities access preferred stimuli or choose among stimulus options. The application of those programs may pose problems when the participants have very limited behavior repertoires and are unable to use conventional responses and microswitches. The present two studies assessed non-conventional response-microswitch solutions for three of those participants. Study I included two participants who were exposed to a program in which forehead skin movement was the response required to access preferred stimulation. The microswitch was an optic sensor combined with a small black sticker on the forehead. Study II included one participant who was exposed to a program in which a smile response was required to choose among stimuli. The microswitch for monitoring the smile was a new camera-based technology. The results of the two studies showed that the response-microswitch solutions were suitable for the participants and enabled them to perform successfully. Implications of the studies for people with limited motor behavior and issues for future research were discussed.

    Adsorption of cellulase on solids resulting from pretreatment of poplar wood by ammonia fiber expansion (AFEX), ammonia recycled percolation (ARP), controlled pH, dilute acid (DA), flowthrough (FT), lime, and sulfur dioxide (SO(2)) and pure Avicel glucan was measured at 4 degrees C, as were adsorption and desorption of cellulase and adsorption of beta-glucosidase for lignin left after enzymatic digestion of the solids from these pretreatments. From this, Langmuir adsorption parameters, cellulose accessibility to cellulase, and the effectiveness of cellulase adsorbed on poplar solids were estimated, and the effect of delignification on cellulase effectiveness was determined. Furthermore, Avicel hydrolysis inhibition by enzymatic and acid lignin of poplar solids was studied. Flowthrough pretreated solids showed the highest maximum cellulase adsorption capacity (sigma(solids) = 195 mg/g solid) followed by dilute acid (sigma(solids) = 170.0 mg/g solid) and lime pretreated solids (sigma(solids) = 150.8 mg/g solid), whereas controlled pH pretreated solids had the lowest (sigma(solids) = 56 mg/g solid). Lime pretreated solids also had the highest cellulose accessibility (sigma(cellulose) = 241 mg/g cellulose) followed by FT and DA. AFEX lignin had the lowest cellulase adsorption capacity (sigma(lignin) = 57 mg/g lignin) followed by dilute acid lignin (sigma(lignin) = 74 mg/g lignin). AFEX lignin also had the lowest beta-glucosidase capacity (sigma(lignin) = 66.6 mg/g lignin), while lignin from SO(2) (sigma(lignin) = 320 mg/g lignin) followed by dilute acid had the highest (301 mg/g lignin). Furthermore, SO(2) followed by dilute acid pretreated solids gave the highest cellulase effectiveness, but delignification enhanced cellulase effectiveness more for high pH than low pH pretreatments, suggesting that lignin impedes access of enzymes to xylan more than to glucan, which in turn affects glucan accessibility. In addition, lignin from enzymatic digestion of AFEX and dilute

    Laser scribing is an attractive reduced graphene oxide (rGO) growth and patterning technology because the process is low-cost, time-efficient, transfer-free, and flexible. Various laser-scribed rGO (LSG) components such as capacitors, gas sensors, and strain sensors have been demonstrated. However, obstacles remain toward practical application of the technology where all the components of a system are fabricated using laser scribing. Memory components, if developed, will substantially broaden the application space of low-cost, flexible electronic systems. For the first time, a low-cost approach to fabricate resistive random access memory (ReRAM) using laser-scribed rGO as the bottom electrode is experimentally demonstrated. The one-step laser scribing technology allows transfer-free rGO synthesis directly on flexible substrates or non-flat substrates. Using this time-efficient laser-scribing technology, the patterning of a memory-array area up to 100 cm(2) can be completed in 25 min. Without requiring the photoresist coating for lithography, the surface of patterned rGO remains as clean as its pristine state. Ag/HfOx/LSG ReRAM using laser-scribing technology is fabricated in this work. Comprehensive electrical characteristics are presented including forming-free behavior, stable switching, reasonable reliability performance and potential for 2-bit storage per memory cell. The results suggest that laser-scribing technology can potentially produce more cost-effective and time-effective rGO-based circuits and systems for practical applications.

    2009-01-01

    This article explores the need for reflection on the right of developing countries to science and technology in addition to explaining the place of the scientific rights of nations in human rights as a whole. The discussion was conducted in relation to sustainable development. Through the examination of the current situation and the challenges to sustainable development, and taking into account the imbalance in the distribution of the benefits of science and new technologies, the authors advocate a comprehensive approach to promote cooperation and capacity-building in this area. They argue that linkages should be adopted between micro-levels and macro-levels of analysis by elevating rights and related issues from individuals to the national level in the field of the right to science and technology, and from the national to the international level in the field of sustainable development in order to institutionalise and ensure individual and national rights to science, technology and sustainable development. The authors also believe in a multidimensional perspective based on the balanced flourishing of the material and immaterial aspects of humankind in order to realise these rights in the context of dialogue and cultural diversity and to promote the culture of sustainable and dynamic peace based on justice in knowledge societies.

    Widespread implementation of integrated primary care and behavioral health is possible, but workforce shortages, competencies to deliver evidence-based approaches, and sufficient reimbursement are lacking. There are numerous telehealth solutions that could be utilized to assist with integration efforts that have the potential to be successfully used alone or in combination. This will require that the developers of such technologies understand the current evidence base for effective integration efforts and apply this knowledge to new solutions. Evidence-based models of integrated care such as the collaborative care model have a robust evidence base including studies that demonstrate effective delivery from remote locations. Technology solutions that can serve as practice extenders by performing some of the tasks, and can expand the competency of primary care providers to treat mild to moderate mental illness, have an emerging literature in the behavioral health arena that shows promise for integrating care. More widespread implementation of effective integrated primary care and behavioral health can be accomplished with the help of technology solutions that can address the problems of workforce shortages and competencies. Use of these technologies alone or in combination is a growing area of research and development and an untapped frontier that warrants further investigation.

  16. Ultrasonic Multiple-Access Ranging System Using Spread Spectrum and MEMS Technology for Indoor Localization

    PubMed Central

    Segers, Laurent; Tiete, Jelmer; Braeken, An; Touhafi, Abdellah

    2014-01-01

    Indoor localization of persons and objects poses a great engineering challenge. Previously developed localization systems demonstrate the use of wideband techniques in ultrasound ranging systems. Direct sequence and frequency hopping spread spectrum ultrasound signals have been proven to achieve a high level of accuracy. A novel ranging method using the frequency hopping spread spectrum with finite impulse response filtering will be investigated and compared against the direct sequence spread spectrum. In the first setup, distances are estimated in a single-access environment, while in the second setup, two senders and one receiver are used. During the experiments, the micro-electromechanical systems are used as ultrasonic sensors, while the senders were implemented using field programmable gate arrays. Results show that in a single-access environment, the direct sequence spread spectrum method offers slightly better accuracy and precision performance compared to the frequency hopping spread spectrum. When two senders are used, measurements point out that the frequency hopping spread spectrum is more robust to near-far effects than the direct sequence spread spectrum. PMID:24553084

    Computer access can play an important role in employment and leisure activities following spinal cord injury. The authors' prior work has shown that a tooth-click detecting device, when paired with an optical head mouse, may be used by people with tetraplegia for controlling cursor movement and mouse button clicks. To compare the efficacy of tooth clicks to speech recognition and that of an optical head mouse to a gyrometer head mouse for cursor and mouse button control of a computer. Six able-bodied and 3 tetraplegic subjects used the devices listed above to produce cursor movements and mouse clicks in response to a series of prompts displayed on a computer. The time taken to move to and click on each target was recorded. The use of tooth clicks in combination with either an optical head mouse or a gyrometer head mouse can provide hands-free cursor movement and mouse button control at a speed of up to 22% of that of a standard mouse. Tooth clicks were significantly faster at generating mouse button clicks than speech recognition when paired with either type of head mouse device. Tooth-click detection performed better than speech recognition when paired with both the optical head mouse and the gyrometer head mouse. Such a system may improve computer access for people with tetraplegia.

    Third-generation reusable launch vehicle (RLV) systems are envisioned that utilize airbreathing and combined-cycle propulsion to take advantage of potential performance benefits over conventional rocket propulsion and address goals of reducing the cost and enhancing the safety of systems to reach earth orbit. The dual-mode scramjet (DMSJ) forms the core of combined-cycle or combination-cycle propulsion systems for single-stage-to-orbit (SSTO) vehicles and provides most of the orbital ascent energy. These concepts are also relevant to two-stage-to-orbit (TSTO) systems with an airbreathing first or second stage. Foundation technology investments in scramjet propulsion are driven by the goal to develop efficient Mach 3-15 concepts with sufficient performance and operability to meet operational system goals. A brief historical review of NASA scramjet development is presented along with a summary of current technology efforts and a proposed roadmap. The technology addresses hydrogen-fueled combustor development, hypervelocity scramjets, multi-speed flowpath performance and operability, propulsion-airframe integration, and analysis and diagnostic tools.

    "Berlin Access", a regional R&D project carried out by six companies and Heinrich Hertz Institute, Fraunhofer Society, is geared towards low cost solutions for fibre access network architectures (PON and CWDM-PON), ONU transceivers, and passive fibre components. Close communication with system manufacturers, non-incumbent carriers, and a city services supplier implementing a local FTTH network supports orientation towards market demands. In this paper we report on a new FTTH transceiver based on an all-polymer PLC motherboard. The waveguides exhibit high transmission, strong optical confinement, and large operation temperature range. Low loss passively adjusted fibre/PLC coupling is achieved by employing a waveguide taper. Downstream/upstream wavelength separation is accomplished by a directional coupler, or, alternatively, a thin film filter inserted into the input/output waveguide (the latter approach also allowing for the provisioning of an overlay broadcasting channel). The horizontal-cavity surface-emitting laser diode, the pin-photodiode (equipped with a thin film filter for improved crosstalk suppression), and the monitor diode are all flip-chip surface mounted; the light being coupled via 45° waveguide mirrors. Chip mounting can be done with a commercial fineplacer using semi-active automatic alignment. Micro-strip lines with impedances adapted to both laser and photodiode are fabricated on the basis of the PLC films. The polymer motherboard integration scheme offers compact transceiver optical subassemblies and lends itself favourably to highly automized, low cost manufacturing with high yield. Extended functionalities like loss of light alarm or concepts for colourless CWDM ONUs can be easily realized with this concept.

    To examine how surgical robot emergence affects prostate-cancer patient behavior in seeking radical prostatectomy focusing on geographical accessibility. In Japan, robotic surgery was approved in April 2012. Based on data in the Japanese Diagnosis Procedure Combination database between April 2012 and March 2014, distance to nearest surgical robot and interval days to radical prostatectomy (divided by mean interval in 2011: % interval days to radical prostatectomy) were calculated for individual radical prostatectomy cases at non-robotic hospitals. Caseload changes regarding distance to nearest surgical robot and robot introduction were investigated. Change in % interval days to radical prostatectomy was evaluated by multivariate analysis including distance to nearest surgical robot, age, comorbidity, hospital volume, operation type, hospital academic status, bed volume and temporal progress. % Interval days to radical prostatectomy became wider for distance to nearest surgical robot <30 km. When a surgical robot emerged within 30 and 10 km, the prostatectomy caseload in non-robot hospitals reduced by 13 and 18% within 6 months, respectively, while the robot hospitals gained +101% caseload (P < 0.01 for all) Multivariate analyses including 9759 open and 5052 non-robotic minimally invasive radical prostatectomies in 483 non-robot hospitals revealed a significant inverse association between distance to nearest surgical robot and % interval days to radical prostatectomy (B = -17.3% for distance to nearest surgical robot ≥30 km and -11.7% for 10-30 km versus distance to nearest surgical robot <10 km), while younger age, high-volume hospital, open-prostatectomy provider and temporal progress were other significant factors related to % interval days to radical prostatectomy widening (P < 0.05 for all). Robotic surgery accessibility within 30 km would make patients less likely select conventional surgery. The nearer a robot was, the faster the caseload reduction was.

  4. Review of naloxone safety for opioid overdose: practical considerations for new technology and expanded public access

    PubMed Central

    2015-01-01

    Opioid overdose and mortality have increased at an alarming rate prompting new public health initiatives to reduce drug poisoning. One initiative is to expand access to the opioid antidote naloxone. Naloxone has a long history of safe and effective use by organized healthcare systems and providers in the treatment of opioid overdose by paramedics/emergency medicine technicians, emergency medicine physicians and anesthesiologists. The safety of naloxone in a prehospital setting administered by nonhealthcare professionals has not been formally established but will likely parallel medically supervised experiences. Naloxone dose and route of administration can produce variable intensity of potential adverse reactions and opioid withdrawal symptoms: intravenous administration and higher doses produce more adverse events and more severe withdrawal symptoms in those individuals who are opioid dependent. More serious adverse reactions after naloxone administration occur rarely and may be confounded by the effects of other co-intoxicants and the effects of prolonged hypoxia. One component of the new opioid harm reduction initiative is to expand naloxone access to high-risk individuals (addicts, abusers, or patients taking high-dose or extended-release opioids for pain) and their close family or household contacts. Patients or their close contacts receive a naloxone prescription to have the medication on their person or in the home for use during an emergency. Contacts are trained on overdose recognition, rescue breathing and administration of naloxone by intramuscular injection or nasal spraying of the injection prior to the arrival of emergency medical personnel. The safety profile of naloxone in traditional medical use must be considered in this new context of outpatient prescribing, dispensing and treatment of overdose prior to paramedic arrival. New naloxone delivery products are being developed for this prehospital application of naloxone in treatment of opioid

  10. Color coded multiple access scheme for bidirectional multiuser visible light communications in smart home technologies

    NASA Astrophysics Data System (ADS)

    Tiwari, Samrat Vikramaditya; Sewaiwar, Atul; Chung, Yeon-Ho

    2015-10-01

    In optical wireless communications, multiple channel transmission is an attractive solution to enhancing capacity and system performance. A new modulation scheme called color coded multiple access (CCMA) for bidirectional multiuser visible light communications (VLC) is presented for smart home applications. The proposed scheme uses red, green and blue (RGB) light emitting diodes (LED) for downlink and phosphor based white LED (P-LED) for uplink to establish a bidirectional VLC and also employs orthogonal codes to support multiple users and devices. The downlink transmission for data user devices and smart home devices is provided using red and green colors from the RGB LEDs, respectively, while uplink transmission from both types of devices is performed using the blue color from P-LEDs. Simulations are conducted to verify the performance of the proposed scheme. It is found that the proposed bidirectional multiuser scheme is efficient in terms of data rate and performance. In addition, since the proposed scheme uses RGB signals for downlink data transmission, it provides flicker-free illumination that would lend itself to multiuser VLC system for smart home applications.

  11. A Time-constrained Network Voronoi Construction and Accessibility Analysis in Location-based Service Technology

    Accessibility analysis usually requires special models of spatial location analysis based on some geometric constructions, such as Voronoi diagram (abbreviated to VD). There are many achievements in classic Voronoi model research, however suffering from the following limitations for location-based services (LBS) applications. (1) It is difficult to objectively reflect the actual service areas of facilities by using traditional planar VDs, because human activities in LBS are usually constrained only to the network portion of the planar space. (2) Although some researchers have adopted network distance to construct VDs, their approaches are used in a static environment, where unrealistic measures of shortest path distance based on assumptions about constant travel speeds through the network were often used. (3) Due to the computational complexity of the shortest-path distance calculating, previous researches tend to be very time consuming, especially for large datasets and if multiple runs are required. To solve the above problems, a novel algorithm is developed in this paper. We apply network-based quadrat system and 1-D sequential expansion to find the corresponding subnetwork for each focus. The idea is inspired by the natural phenomenon that water flow extends along certain linear channels until meets others or arrives at the end of route. In order to accommodate the changes in traffic conditions, the length of network-quadrat is set upon the traffic condition of the corresponding street. The method has the advantage over Dijkstra's algorithm in that the time cost is avoided, and replaced with a linear time operation.

    As clinical imaging and informatics systems continue to integrate the healthcare enterprise, the need to prevent patient mis-identification and unauthorized access to clinical data becomes more apparent especially under the Health Insurance Portability and Accountability Act (HIPAA) mandate. Last year, we presented a system to track and verify patients and staff within a clinical environment. This year, we further address the biometric verification component in order to determine which Biometric system is the optimal solution for given applications in the complex clinical environment. We install two biometric identification systems including fingerprint and facial recognition systems at an outpatient imaging facility, Healthcare Consultation Center II (HCCII). We evaluated each solution and documented the advantages and pitfalls of each biometric technology in this clinical environment.

    With the large-scale construction of special high-voltage project, as well as power supply reliability, security, economic and other increasingly demanding, state monitoring equipment involved in more and more monitoring projects and more and more monitoring data, because these data exist in multiple isolated systems in the Ultra-High Voltage(UHV) AC-DC substation, there is no data sharing mechanism, so a holistic analysis, application and sharing approach for the data set will need a deep consideration. In this paper, the equipment condition monitoring system frame of the UHV converter station and the scheme of the equipment state data access of UHV converter station based on the multi-source and heterogeneous data fusion are presented. Then, data exchange technology of UHV equipment state early warning center was introduced, and a data access and conversion device in the Zhongzhou converter station was deployed to solve the timeliness and functionality difficult of the existing system to meet the requirements of UHV operation and maintenance support.

    The Oxford Clinical Intranet provides clinicians in primary and secondary care across Oxfordshire with: Access to information about their patients held on multiple remote disparate computer systems, including admissions and episodes, Laboratory Medicine reports, Radiology reports and hospital discharge letters. The patient records are managed using CSW Case Notes. Access to support and advisory information, developed both within the organization and collected from other sites and projects, a wide range of internal handbooks, directories and guidelines and links to external resources, including evidence-based resources, the Cochrane Collaboration and the NHS National electronic Library of Health. Automated retrieval and presentation of the support information that is contextually appropriate to the task being carried out by the clinician and the information held about the patient. For example laboratory reports are linked to handbooks and other reference sources using eLABook, a web-interfaced database subsystem. Internet technology has been used throughout, thus providing a thin-client architecture with cross-platform ability. Appropriate data standards have been used across the communicating systems and the intranet is compliant with the UK eGovernment Interoperability Framework. The intranet was developed at low cost and is now in routine use. This approach appears to be transferable across systems and organisations.

    To systematically quantify the impact of consumer cost on assisted reproduction technology (ART) utilization and numbers of embryos transferred. Ordinary least squared (OLS) regression models were constructed to measure the independent impact of ART affordability-measured as consumer cost relative to average disposable income-on ART utilization and embryo transfer practices. Not applicable. Women undergoing ART treatment. None. OLS regression coefficient for ART affordability, which estimates the independent effect of consumer cost relative to income on utilization and number of embryos transferred. ART affordability was independently and positively associated with ART utilization with a mean OLS coefficient of 0.032. This indicates that, on average, a decrease in the cost of a cycle of 1 percentage point of disposable income predicts a 3.2% increase in utilization. ART affordability was independently and negatively associated with the number of embryos transferred, indicating that a decrease in the cost of a cycle of 10 percentage points of disposable income predicts a 5.1% increase in single-embryo transfer cycles. The relative cost that consumers pay for ART treatment predicts the level of access and number of embryos transferred. Policies that affect ART funding should be informed by these findings to ensure equitable access to treatment and clinically responsible embryo transfer practices.

    Tongue Drive System (TDS) is a wireless and wearable assistive technology (AT) that enables people with severe disabilities to control their computers, wheelchairs, and electronic gadgets using their tongue motion. We developed the TDS to control smartphone's (iPhone/iPod Touch) built-in and downloadable apps with a customized Bluetooth mouse module by emulating finger taps on the touchscreen. The TDS-iPhone Bluetooth mouse interface was evaluated by four able-bodied subjects to complete a scenario consisting of seven tasks, which were randomly ordered by using touch on the iPhone screen with index finger, a computer mouse on iPhone, and TDS-iPhone Bluetooth mouse interface with tongue motion. Preliminary results show that the average completion times of a scenario with touch, mouse, and TDS are 165.6 ± 14.50 s, 186.1 ± 15.37 s, and 651.6 ± 113.4 s, respectively, showing that the TDS is 84.37% and 81.16% slower than touch and mouse for speed of typing with negligible errors. Overall, considering the limited number of commands and unfamiliarity of the subjects with the TDS, we achieved acceptable results for hands-free functionality. PMID:23366818

    Behavioral parent training (BPT) has been shown to be efficacious to improve parenting skills for problematic interactions with adolescents displaying oppositional and antisocial behaviors. Some research suggests that support group curricula might be transferred to the Internet, and some studies suggest that other curriculum designs might also be effective. In this research, a BPT program for parents of at-risk adolescents was tested on the Internet in a randomized trial (N = 307) from computer labs at six community technology centers in or near large metropolitan areas. The instructional design was based on asynchronous scenario-based e-learning, rather than a traditional parent training model where presentation of course material builds content sequentially over multiple class sessions. Pretest to 30-day follow-up analyses indicated significant treatment effects on parent-reported discipline style (Parenting Scale, Adolescent version), child behavior (Eyberg Child Behavior Inventory), and on social cognitive theory constructs of intentions and self-efficacy. The effect sizes were small to medium. These findings suggest the potential to provide effective parent training programs on the Internet.

    2012-12-01

    The combination of ocean observatory infrastructure and automated submersible flow cytometry can provide unprecedented capability for sustained high resolution time series of plankton, including taxa that are harmful or early indicators of ecosystem response to environmental change. Over the past decade, we have developed the FlowCytobot series of instruments that exemplify this capability. FlowCytobot and Imaging FlowCytobot use a combination of laser-based scattering and fluorescence measurements and video imaging of individual particles to enumerate and characterize cells ranging from picocyanobacteria to large chaining-forming diatoms. The process of developing these complex instruments was streamlined by access to the Martha's Vineyard Coastal Observatory (MVCO), a cabled facility on the New England Shelf, where real time two-way communications and access to shore power expedited cycles of instrument evaluation and design refinement. Repeated deployments at MVCO, typically 6 months in duration, have produced multi-year high resolution (hourly to daily) time series that are providing new insights into dynamics of community structure such as blooms, seasonality, and possibly even trends linked to regional climate change. The high temporal resolution observations of single cell properties make it possible not only to characterize taxonomic composition and size structure, but also to quantify taxon-specific growth rates. To meet the challenge of broadening access to this enabling technology, we have taken a two-step approach. First, we are partnering with a few scientific collaborators interested in using the instruments in different environments and to address different applications, notably the detection and characterization of harmful algal bloom events. Collaboration at this stage ensured that these first users outside the developers' lab had access to technical know-how required for successful outcomes; it also provided additional feedback that could be

    The current study examined by mixed method the effectiveness of an accessibility to Information and Communications Technology (ICT) program that provided computers, assistive technology, tutors, and internet connection to 65 youths with severe disabilities (aged 13.22 ± 3.4 years) in their homes. The quantitative evaluation included assessment of computer task performance, computer skills, and participation in social ICT leisure activities before and after the program. Findings revealed low baseline and significant progress on most outcome measures 6 months after the program, mostly among those youths who had tutors. Additional in-depth interviews were conducted 1 year later with 10 participants to explore their ICT use and its impact on their social participation. The analysis revealed a significant contribution of the ICT use, while critical thinking about its risks and some disappointment with the social needs that ICT does not address. Our findings raise awareness of 'two-way streets' policies and programs to ensure e-inclusion. Copyright © 2014 John Wiley & Sons, Ltd.

    Objective The goal of this trial is to evaluate a novel intervention designed to improve post-hospitalization support for older adults with chronic conditions via: (a) direct tailored communication to patients using regular automated calls post discharge, (b) support for informal caregivers outside of the patient’s household via structured automated feedback about the patient’s status plus advice about how caregivers can help, and (c) support for care management including a web-based disease management tool and alerts about potential problems. Methods 846 older adults with common chronic conditions are being identified upon hospital admission. Patients are asked to identify a “CarePartner” (CP) living outside their household, i.e., an adult child or other social network member willing to play an active role in their post-discharge transition support. Patient-CP pairs are randomized to the intervention or usual care. Intervention patients receive automated assessment and behavior change calls, and their CPs receives structured feedback and advice via email and automated calls following each assessment. Clinical teams have access to assessment results via the web and receive automated reports about urgent health problems. Patients complete surveys at baseline, 30 days, and 90 days post discharge; utilization data is obtained from hospital records. CPs, other caregivers, and clinicians are interviewed to evaluate intervention effects on processes of self-care support, caregiver stress and communication, and the intervention’s potential for broader implementation. The primary outcome is 30-day readmission rates; other outcomes measured at 30 days and 90 days include functional status, self-care behaviors, and mortality risk. Conclusion This trial uses accessible health technologies and coordinated communication among informal caregivers and clinicians to fill the growing gap between what discharged patients need and available resources.

    Worldwide, billions of dollars are invested in medical product development and there is an increasing pressure to maximize the revenues of these investments. That is, governments need to be informed about the benefits of spending public resources, companies need more information to manage their product development portfolios and even universities may need to direct their research programmes in order to maximize societal benefits. Assuming that all medical products need to be adopted by the heavily regulated healthcare market at one point in time, it is worthwhile to look at the logic behind healthcare decision making, specifically, decisions on the coverage of medical products and decisions on the use of these products under competing and uncertain conditions. With the growing tension between leveraging economic growth through R&D spending on the one hand and stricter control of healthcare budgets on the other, several attempts have been made to apply the health technology assessment (HTA) methodology to earlier stages of technology development and implementation. For instance, horizon scanning was introduced to systematically assess emerging technologies in order to inform health policy. Others have introduced iterative economic evaluation, e.g. economic evaluations in earlier stages of clinical research. However, most of these methods are primarily intended to support governments in making decisions regarding potentially expensive new medical products. They do not really inform biomedical product developers on the probability of return on investment, nor do they inform about the market needs and specific requirements of technologies in development. It is precisely this aspect that increasingly receives attention, i.e. is it possible to use HTA tools and methods to inform biomedical product development and to anticipate further development and market access. Several methods have been used in previous decades, but have never been compiled in a comprehensive review

    In this paper, the authors explore the use of mobile devices as assistive technology for students with visual impairments in resource-limited environments. This paper provides initial data and analysis from an ongoing project in Kenya using tablet devices to provide access to education and independence for university students with visual impairments in Kenya. The project is a design-based research project in which we have developed and are refining a theoretically grounded intervention--a model for developing communities of practice to support the use of mobile technology as an assistive technology. We are collecting data to assess the efficacy and improve the model as well as inform the literature that has guided the design of the intervention. In examining the impact of the use of mobile devices for the students with visual impairments, we found that the devices provide the students with (a) access to education, (b) the means to participate in everyday life and (c) the opportunity to create a community of practice. Findings from this project suggest that communities of practice are both a viable and a valuable approach for facilitating the diffusion and support of mobile devices as assistive technology for students with visual impairments in resource-limited environments. Implications for Rehabilitation The use of mobile devices as assistive technology in resource-limited environments provides students with visual impairments access to education and enhanced means to participate in everyday life. Communities of practice are both a viable and a valuable approach for facilitating the diffusion and support of mobile devices as assistive technology for students with visual impairments in resource-limited environments. Providing access to assistive technology early and consistently throughout students' schooling builds both their skill and confidence and also demonstrates the capabilities of people with visual impairments to the larger society.

    2017-09-27

    Remote, rugged and extraordinarily beautiful, Alaska’s Aleutian Islands are best known for wildlife reserves, military bases, fishing, furs and fog. The sprawling volcanic archipelago was brought into the spotlight by the Russian-supported expedition of Alexey Chirikov and Vitus Bering in 1741, and soon became controlled by the Russian-American Fur Company. In 1867 the United States purchased Alaska, including the Aleutian Islands, from Russia. By 1900 the port in Unalaska was well established as a shipping port for Alaska gold. The archipelago sweeps about 1,200 miles (1,800 km) from the tip of the Alaskan Peninsula to Attu, the most westward island. Four major island groups hold 14 large islands, about 55 smaller islands, and a large number of islets, adding up to roughly 150 islands/islets in total. This chain separates the Bering Sea (north) from the Pacific Ocean (south) and the islands are connected by the Marine Highway Ferry – at least as far as Unalaska. For the most remote islands, such as birding paradise of Attu, the western-most Aleutian Island, travel becomes trickier and relies primarily on custom charter. The Moderate Resolution Imaging Spectroradiometer (MODIS) flew over the region and captured this spectacular true-color image of the eastern Aleutian Islands on May 15, 2014. In this image, the Alaskan Peninsula protrudes from the mainland and sweeps to the southwest. The first set of islands are called the Fox Island group. Unalaska Island is part of this group and can be identified, with some imagination, as an island formed in the shape of a flying cherub, with two arms (peninsulas) outstretched towards the northeast, seemingly reaching for the round “balls” of Akutan and Akun Islands. The smallest islands in the west of the image belong to the group known as the Islands of Four Mountains. The Aleutians continue far to the west of this image. Fog surrounds the Aleutians, stretching from just off the southwestern Alaska mainland to the

    Usability evaluations are necessary to determine the feasibility of nurses' interactions with computerized clinical decision-support systems. Limitations and challenges of operations that inhibit or facilitate utilization in clinical practice can be identified. This study provided nurses with mobile information terminals, PDAs and tablet PCs, to improve point-of-care access to information. The purpose of this study was to determine usability issues associated with point-of-care technology. Eleven nurses were self-selected. Nurses were videotaped and audiotaped completing four tasks, including setting up the device and three resource search exercises. A research team member completed a usability checklist. Completion times for each task, success rate, and challenges experienced were documented. Four participants completed all tasks, with an average time of 3 minutes 22 seconds. Three participants were unable to complete any of the three tasks. Navigating within resources caused the greatest occurrence of deviations with 39 issues among all participants. Results of the usability evaluation suggest that nurses require a device that (1) is manageable to navigate and (2) utilizes a user-friendly interface, such as a one-time log-in system. Usability testing can be helpful to organizations as they document issues to be cognizant of during the implementation process, increasing the potential for successful implementation and sustained usability.

    The uptake of minimal access surgery (MAS) has by virtue of its clinical benefits become widespread across the surgical specialties. However, despite its advantages in reducing traumatic insult to the patient, it imposes significant ergonomic restriction on the operating surgeons who require training for the safe execution. Recent progress in manipulator technologies (robotic or mechanical) have certainly reduced the level of difficulty, however it requires information for a complete gesture analysis of surgical performance. This article reports on the development and evaluation of such a system capable of full biomechanical and machine learning. The system for gesture analysis comprises 5 principal modules, which permit synchronous acquisition of multimodal surgical gesture signals from different sources and settings. The acquired signals are used to perform a biomechanical analysis for investigation of kinematics, dynamics, and muscle parameters of surgical gestures and a machine learning model for segmentation and recognition of principal phases of surgical gesture. The biomechanical system is able to estimate the level of expertise of subjects and the ergonomics in using different instruments. The machine learning approach is able to ascertain the level of expertise of subjects and has the potential for automatic recognition of surgical gesture for surgeon-robot interactions. Preliminary tests have confirmed the efficacy of the system for surgical gesture analysis, providing an objective evaluation of progress during training of surgeons in their acquisition of proficiency in MAS approach and highlighting useful information for the design and evaluation of master-slave manipulator systems. © The Author(s) 2013.

    The UMTS Bearer Independent Core Network program introduced the 3rd Generation Partnership Program Release 4 BICN architecture into the legacy UMTS TDM-switched network. BICN is the application of calI server archltecture for voice and circuit switched data, enabling the provisioning of traditional circuit-switched services using a packet-switched transport network. Today"s business climate has made it essential for service providers to develop a comprehensive networking strategy that means introduction of RCBICN networks. The R4-BICN solution to the evolution of the Core Network in UMTS will enable operators to significantly reduce the capital and operational costs of delivering both traditional voice sewices and new multimedia services. To build the optical backbone, which can support the third generation (3G) packetized infrastructure, the operators could choose a fibre connection, or they could retain the benefits of a wireless connectivity by using a FSO - Free Space Optical lmk, the only wireless technology available that is capable of achieving data rates up to 2.4 Gbit/s. FSO offers viable alternatives for both core transmission networks and for replacing microwaves links in NodeB - RNC access networks. The paper and presentation aim to demonstrate the manner in which FSO products and networks are employed into R4-BICN design solutions.

  2. Grand Canyon as a universally accessible virtual field trip for intro Geoscience classes using geo-referenced mobile game technology

    There is a well-documented and nationally reported trend of declining interest, poor preparedness, and lack of diversity within U.S. students pursuing geoscience and other STEM disciplines. We suggest that a primary contributing factor to this problem is that introductory geoscience courses simply fail to inspire (i.e. they are boring). Our experience leads us to believe that the hands-on, contextualized learning of field excursions are often the most impactful component of lower division geoscience classes. However, field trips are becoming increasingly more difficult to run due to logistics and liability, high-enrollments, decreasing financial and administrative support, and exclusivity of the physically disabled. Recent research suggests that virtual field trips can be used to simulate this contextualized physical learning through the use of mobile devices - technology that exists in most students' hands already. Our overarching goal is to enhance interest in introductory geoscience courses by providing the kinetic and physical learning experience of field trips through geo-referenced educational mobile games and test the hypothesis that these experiences can be effectively simulated through virtual field trips. We are doing this by developing "serious" games for mobile devices that deliver introductory geology material in a fun and interactive manner. Our new teaching strategy will enhance undergraduate student learning in the geosciences, be accessible to students of diverse backgrounds and physical abilities, and be easily incorporated into higher education programs and curricula at institutions globally. Our prototype involves students virtually navigating downstream along a scaled down Colorado River through Grand Canyon - physically moving around their campus quad, football field or other real location, using their smart phone or a tablet. As students reach the next designated location, a photo or video in Grand Canyon appears along with a geological

    This true-color image of the Galapagos Islands was acquired on March 12, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra satellite. The Galapagos Islands, which are part of Ecuador, sit in the Pacific Ocean about 1000 km (620 miles) west of South America. As the three craters on the largest island (Isabela Island) suggest, the archipelago was created by volcanic eruptions, which took place millions of years ago. Unlike most remote islands in the Pacific, the Galapagos have gone relatively untouched by humans over the past few millennia. As a result, many unique species have continued to thrive on the islands. Over 95 percent of the islands' reptile species and nearly three quarters of its land bird species cannot be found anywhere else in the world. Two of the more well known are the Galapagos giant tortoise and marine iguanas. The unhindered evolutionary development of the islands' species inspired Charles Darwin to begin The Origin of Species eight years after his visit there. To preserve the unique wildlife on the islands, the Ecuadorian government made the entire archipelago a national park in 1959. Each year roughly 60,000 tourists visit these islands to experience what Darwin did over a century and a half ago. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC

    Technology-assisted treatment (TAT) can be an effective supplement to established face-to-face therapy modalities with a growing literature in substance use disorder (SUD) treatment. TAT access, interest, and familiarity are potential limitations to the use and efficacy of these approaches to treatment. 174 participants in outpatient SUD treatment were administered a survey regarding technology device and Internet access, and interest in engaging in TAT SUD counseling (SUDC). The group was dichotomized by mean age and gender to examine potential variations in in these subgroups. Forty-three (43%) of participants were female, and the mean age was 44.8 years, and 89% of participants had Internet access. 83% of participants were interested in TAT for SUD counseling; 81% expected it to be at least "moderately helpful." 34% of participants noted they would choose to continue face-to-face therapy exclusively. 91% of participants had cell phones, but only 50% could access data or the Internet via their handheld device. 80% of participants stated they would be interested in trying SUDC via their phone. Women had a higher preference for computer-based SUDC than men, with gender being significantly correlated with TAT perceive helpfulness. These findings suggest that patients in outpatient SUD treatment have access to resources for TAT implementation, although access was not always readily available. Future research will be needed to determine whether the technology that this population possesses will be able to support the evolving TAT modalities and whether interest in TAT across age and gender groups equalizes over time.

    We have developed 4D volume processing and attribute analysis algorithms to identify significant seismic changes over time that result from drainage of oil and gas within reservoirs. The 4D seismic monitoring methodology merges the computational simulation of expected changes in acoustic reflectivity from drainage with the observed snapshots of the real reservoir impedance changes. We demonstrate its utility in the Eugene Island 330 field of offshore Louisiana, where 4 generations of 3D seismic surveys have been acquired; fire in 1985, then in 1988, 1992 and again in 1994. These datasets contain seismic snapshots of the field as it has been drained of more than 100 million barrels of oil equivalents. Dim-outs were detected where production depleted oil and gas, and amplitude increases were observed where secondary gas caps formed. The [open quotes]oil/water contact[close quotes] movement was also detected by the 4D technique. When combined with active pressure and temperature monitoring, production history matching, and Sw changes detected in cased-hole pulsed-neutron logs, 4D seismic imaging of producing fields promises to allow real-time production control in the future.

    Information and communication technology (ICT) tools are known to facilitate communication and processing of information and sharing of knowledge by electronic means. In Nigeria, the lack of adequate capacity on the use of ICT by health sector policymakers constitutes a major impediment to the uptake of research evidence into the policymaking process. The objective of this study was to improve the knowledge and capacity of policymakers to access and utilize policy relevant evidence. A modified "before and after" intervention study design was used in which outcomes were measured on the target participants both before the intervention is implemented and after. A 4-point likert scale according to the degree of adequacy; 1 = grossly inadequate, 4 = very adequate was employed. This study was conducted in Ebonyi State, south-eastern Nigeria and the participants were career health policy makers. A two-day intensive ICT training workshop was organized for policymakers who had 52 participants in attendance. Topics covered included: (i). intersectoral partnership/collaboration; (ii). Engaging ICT in evidence-informed policy making; use of ICT for evidence synthesis; (iv) capacity development on the use of computer, internet and other ICT. The pre-workshop mean of knowledge and capacity for use of ICT ranged from 2.19-3.05, while the post-workshop mean ranged from 2.67-3.67 on 4-point scale. The percentage increase in mean of knowledge and capacity at the end of the workshop ranged from 8.3%-39.1%. Findings of this study suggest that policymakers' ICT competence relevant to evidence-informed policymaking can be enhanced through training workshop.

    The purpose of this article is to describe the impact of an intervention involving safe-laser pointing technology on six persons with locked-in syndrome. When these individuals were invited to participate in this project (4 weeks to 18 years post onset), none were able to speak and none were able to access an augmentative and alternative communication (AAC) device. All communicated using eye movements (e.g., looking up or down), eye blinks, dependent scanning strategies with eye movement signals, or eye linking. Following intervention with the Safe-Laser Access System, three of the six participants developed head movement sufficient to control AAC technology. Two participants continue to develop head control; however, their progress has been slowed by repeated illnesses. One participant has discontinued his involvement with the project because of medical and psychological concerns. These six participants represent consecutive referrals to the project.

  18. Small population instability and island settlement patterns.

    Williamson, I; Sabath, M D

    1984-03-01

    This study used data from the Marshall Islands to examine the relationship between settlement pattern within an island group to the stability of potential population inhabiting those islands. It was hypothesized that extinction probability (based on island carrying capacity, frequency and amplitude of fluctuation in resources determining carrying capacity, and the net costs of contact and exchange between population units) will determine island settlement patterns, resulting in nonsettlement of islands with low carrying capacities and settlement of all islands with high carrying capacities. The Marshall Island group includes both settled and unsettled islands, and represents a homogeneous culture that has remained unchanged for many generations. The mesophytic index (rainfall x land area), used as an indicator of atoll human carrying capacity, was related to island settlement patterns. No atolls with mesophytic indices exceeding 2000 units were uninhabited, although 4 with values under 2000 units were inhabited, suggesting an overlap zone between inhabitable and uninhabitable islands. Population size and settlement existence were also related. Only 2 of 21 inhabited islands had populations below 100, and none of the uninhabited islands contained more than 78 individuals. These results may be of relevance to earlier atoll colonization patterns. The prerequisites for atoll colonization appear to have been colonizing groups exceeding 80 individuals, contact with an established population source, and a horticultural subsistence mode and maritime technology. It is concluded that small population instability should be considered in terms of the colonization process and settlement pattern of island groups.

  19. Restricting Access to ART on the Basis of Criminal Record : An Ethical Analysis of a State-Enforced "Presumption Against Treatment" With Regard to Assisted Reproductive Technologies.

    2015-09-01

    As assisted reproductive technologies (ART) become increasingly popular, debate has intensified over the ethical justification for restricting access to ART based on various medical and non-medical factors. In 2010, the Australian state of Victoria enacted world-first legislation that denies access to ART for all patients with certain criminal or child protection histories. Patients and their partners are identified via a compulsory police and child protection check prior to commencing ART and, if found to have a previous relevant conviction or child protection order, are given a "presumption against treatment." This article reviews the legislation and identifies arguments that may be used to justify restricting access to ART for various reasons. The arguments reviewed include limitations of reproductive rights, inheriting undesirable genetic traits, distributive justice, and the welfare of the future child. We show that none of these arguments justifies restricting access to ART in the context of past criminal history. We show that a "presumption against treatment" is an unjustified infringement on reproductive freedom and that it creates various inconsistencies in current social, medical, and legal policy. We argue that a state-enforced policy of restricting access to ART based on the non-medical factor of past criminal history is an example of unjust discrimination and cannot be ethically justified, with one important exception: in cases where ART treatment may be considered futile on the basis that the parents are not expected to raise the resulting child.

    The concept of community access is a multidimensional term, which may involve issues related to physical access, knowledge and information, power and control, relationships and communications, advocacy, participation and quality of life [21]. This paper discusses historical and emerging practices and interventions related to physical access to community and community based information for individuals with cognitive disabilities such as intellectual disability, autism or traumatic brain injury. While much societal attention has been paid to features of independent community access for populations such as individuals with hearing, vision or physical disabilities, less attention has focused on independent community access for people with intellectual and other significant cognitive disabilities. Attitudes and actions by families and professional service communities are often mixed for some individuals in this population. The somewhat limited research base in these areas is explored, including a case study review and results from several promising feasibility studies. The paper concludes with comments concerning future prospects and recommendations for improving independent community access for persons with significant cognitive disabilities.
