    In these years, multilingual system becomes important, but, most computer environment cannot handle all languages (scripts) in ths world. This paper presents a multilingual imaging system on the Internet. In this system, characters are converted into bitmaps, and therefore, we can display multilingual text on WWW browsers. In order to convert multilingual plain text into bitmap images, we have developed software named ctext2pgm and VFlib. VFlib is a software component to rasterize fonts in various file formats, and ctext2pgm generates bitmap image files form multilingual plain texts. Ctext2pgm is an application program of VFlib, and it supports about 30 languages. We also introduce a language education system for various languages. This is an example of the multilingual system using internet imaging.

  2. Preprocessing Inconsistent Linear System for a Meaningful Least Squares Solution

    NASA Technical Reports Server (NTRS)

    Sen, Syamal K.; Shaykhian, Gholam Ali

    2011-01-01

    Mathematical models of many physical/statistical problems are systems of linear equations. Due to measurement and possible human errors/mistakes in modeling/data, as well as due to certain assumptions to reduce complexity, inconsistency (contradiction) is injected into the model, viz. the linear system. While any inconsistent system irrespective of the degree of inconsistency has always a least-squares solution, one needs to check whether an equation is too much inconsistent or, equivalently too much contradictory. Such an equation will affect/distort the least-squares solution to such an extent that renders it unacceptable/unfit to be used in a real-world application. We propose an algorithm which (i) prunes numerically redundant linear equations from the system as these do not add any new information to the model, (ii) detects contradictory linear equations along with their degree of contradiction (inconsistency index), (iii) removes those equations presumed to be too contradictory, and then (iv) obtain the minimum norm least-squares solution of the acceptably inconsistent reduced linear system. The algorithm presented in Matlab reduces the computational and storage complexities and also improves the accuracy of the solution. It also provides the necessary warning about the existence of too much contradiction in the model. In addition, we suggest a thorough relook into the mathematical modeling to determine the reason why unacceptable contradiction has occurred thus prompting us to make necessary corrections/modifications to the models - both mathematical and, if necessary, physical.

  4. Internetting tactical security sensor systems

    Gage, Douglas W.; Bryan, W. D.; Nguyen, Hoa G.

    1998-08-01

    The Multipurpose Surveillance and Security Mission Platform (MSSMP) is a distributed network of remote sensing packages and control stations, designed to provide a rapidly deployable, extended-range surveillance capability for a wide variety of military security operations and other tactical missions. The baseline MSSMP sensor suite consists of a pan/tilt unit with video and FLIR cameras and laser rangefinder. With an additional radio transceiver, MSSMP can also function as a gateway between existing security/surveillance sensor systems such as TASS, TRSS, and IREMBASS, and IP-based networks, to support the timely distribution of both threat detection and threat assessment information. The MSSMP system makes maximum use of Commercial Off The Shelf (COTS) components for sensing, processing, and communications, and of both established and emerging standard communications networking protocols and system integration techniques. Its use of IP-based protocols allows it to freely interoperate with the Internet -- providing geographic transparency, facilitating development, and allowing fully distributed demonstration capability -- and prepares it for integration with the IP-based tactical radio networks that will evolve in the next decade. Unfortunately, the Internet's standard Transport layer protocol, TCP, is poorly matched to the requirements of security sensors and other quasi- autonomous systems in being oriented to conveying a continuous data stream, rather than discrete messages. Also, its canonical 'socket' interface both conceals short losses of communications connectivity and simply gives up and forces the Application layer software to deal with longer losses. For MSSMP, a software applique is being developed that will run on top of User Datagram Protocol (UDP) to provide a reliable message-based Transport service. In addition, a Session layer protocol is being developed to support the effective transfer of control of multiple platforms among multiple control

    NASA Astrophysics Data System (ADS)

    Vachliotis, Theodoros; Salta, Katerina; Tzougraki, Chryssa

    2014-04-01

    The purpose of this study was dual: First, to develop and validate assessment schemes for assessing 11th grade students' meaningful understanding of organic chemistry concepts, as well as their systems thinking skills in the domain. Second, to explore the relationship between the two constructs of interest based on students' performance on the applied assessment framework. For this purpose, (a) various types of objective assessment questions were developed and evaluated for assessing meaningful understanding, (b) a specific type of systemic assessment questions (SAQs) was developed and evaluated for assessing systems thinking skills, and (c) the association between students' responses on the applied assessment schemes was explored. The results indicated that properly designed objective questions can effectively capture aspects of students' meaningful understanding. It was also found that the SAQs can elicit systems thinking skills in the context of a formalistic systems thinking theoretical approach. Moreover, a significant relationship was observed between students' responses on the two assessment strategies. This research provides evidence that students' systems thinking level within a science domain is significantly related to their meaningful understanding of relative science concepts.

  8. The Omaha system and meaningful use: applications for practice, education, and research.

    Martin, Karen S; Monsen, Karen A; Bowles, Kathryn H

    2011-01-01

    Meaningful use has become ubiquitous in the vocabulary of health information technology. It suggests that better healthcare does not result from the adoption of technology and electronic health records, but by increasing interoperability and informing clinical decisions at the point of care. Although the initial application of meaningful use was limited to eligible professionals and hospitals, it incorporates complex processes and workflow that involve all nurses, other healthcare practitioners, and settings. The healthcare community will become more integrated, and interdisciplinary practitioners will provide enhanced patient-centered care if electronic health records adopt the priorities of meaningful use. Standardized terminologies are a necessary component of such electronic health records. The Omaha System is an exemplar of a standardized terminology that enables meaningful use of clinical data to support and improve patient-centered clinical practice, education, and research. It is user-friendly, generates data that can be shared with patients and their families, and enables healthcare providers to analyze and exchange patient-centered coded data. Use of the Omaha System is increasing steadily in diverse practice, education, and research settings nationally and internationally.

    Bohley, M.C.; Schwartz, M.E.

    1998-03-04

    The objective of this project was to develop an Internet-based electronic performance support system (EPSS) for cellular manufacturing providing hardware/software specifications, process descriptions, estimated cost savings, manufacturing simulations, training information, and service resources for government and industry users of Cincinnati Milacron machine tools and products. AlliedSignal Federal Manufacturing and Technologies (ASFM and T) used expertise in the areas of Internet design and multimedia creation to develop a performance support system (PSS) for the Internet with assistance from CM's subject matter experts from engineering, manufacturing, and technical support. Reference information was both created and re-purposed from other existing formats, then made available on the Internet. On-line references on cellular manufacturing operations include: definitions of cells and cellular manufacturing; illustrations on how cellular manufacturing improves part throughput, resource utilization, part quality, and manufacturing flexibility; illustrations on how cellular manufacturing reduces labor and overhead costs; identification of critical factors driving decisions toward cellular manufacturing; a method for identifying process improvement areas using cellular manufacturing; a method for customizing the size of cells for a specific site; a simulation for making a part using cellular manufacturing technology; and a glossary of terms and concepts.

    In our study we analyze how to create the systems based on “communication-resource-presence”- technology. We formulate functional and architectural requirements. It is shown some new features in this systems that pertain to communication and information search on the Internet. The Internet passed three infrastructure stages from the communication between two hosts to the resource intermediation and communication in real presence systems. The systems based on the presence technologies have just started to develop. Our study shows what criteria’s they must meet. One of this criteria is the division of site resources into the "rooms" logically separated from each other. The users can see and connect to each other. The contextual data of user presence in a particular "room" can be used when searching for them in the context of professional competence.

  13. Earth System Science and the Internet

    NASA Astrophysics Data System (ADS)

    Johnson, Donald R.; Ruzek, Martin; Kalb, Mike

    2000-07-01

    In 1991, NASA and the Universities Space Research Association (USRA) initiated a program to introduce college undergraduates to the interdisciplinary challenges of an emerging Earth system science approach to understanding our planet. Earth system science views the Earth as a synergistic physical system of interrelated phenomena, processes and cycles which remain largely unexplored in traditional disciplinary Earth science course offerings. The ongoing Cooperative University-based Program for Earth System Science Education (ESSE) challenges colleges and universities to develop and offer classroom courses which examine the Earth as a system and to share their progress, course materials and learning modules. Concurrent with the development of the ESSE community and its shared learning resources has been the exponential growth of the Internet and its suite of communication tools, which are a central resource for the ESSE Program. The Internet has enabled the rapid deployment of information and resources through shared repositories of learning materials and general Earth system science knowledge, all of which serve to create and maintain an active informed education community. ESSE participants are organizing to develop a suite of web-based Earth system science learning modules and sharing course materials and learning resources via the ESSE web site. The modular approach more easily assimilates peer-reviewed learning resources into a wide range of classroom environments. A web-based peer-reviewed Journal of Earth System Science Education is proposed to provide educators with quality classroom materials addressing the Earth as a system and to reward ESS resource developers with citable references. More sophisticated web search and retrieval functions, as well as advanced communication tools will be needed to maintain automated databases of networked resources and an informed user community as Earth system science and the Internet enter the new millennium.

    2015-11-01

    This paper presents an Internet of Things (IoT)-enabled dependable control system (DepCS) for continuous processes. In a DepCS, an actuator and a transmitter form a regulatory control loop. Each processor inside such actuator and transmitter is designed as a computational platform implementing the feedback control algorithm. The connections between actuators and transmitters via IoT create a reliable backbone for a DepCS. The centralized input-output marshaling system is not required in DepCSs. A state feedback control synthesis method for DepCS applying the self-recovery constraint is presented in the second part of the paper.

  16. Detecting Fraud in Internet Auction Systems

    NASA Astrophysics Data System (ADS)

    Peng, Yanlin; Zhang, Linfeng; Guan, Yong

    Fraud compromises the thriving Internet auction market. Studies have shown that fraudsters often manipulate their reputations through sophisticated collusions with accomplices, enabling them to defeat the reputation-based feedback systems that are used to combat fraud. This paper presents an algorithm that can identify colluding fraudsters in real time. Experiments with eBay transaction data show that the algorithm has low false negative and false positive rates. Furthermore, the algorithm can identify fraudsters who are innocent at the time of the data collection, but engage in fraudulent transactions soon after they accumulate good feedback ratings.

  17. Utilizing Internet Technologies in Observatory Control Systems

    NASA Astrophysics Data System (ADS)

    Cording, Dean

    2002-12-01

    The 'Internet boom' of the past few years has spurred the development of a number of technologies to provide services such as secure communications, reliable messaging, information publishing and application distribution for commercial applications. Over the same period, a new generation of computer languages have also developed to provide object oriented design and development, improved reliability, and cross platform compatibility. Whilst the business models of the 'dot.com' era proved to be largely unviable, the technologies that they were based upon have survived and have matured to the point were they can now be utilized to build secure, robust and complete observatory control control systems. This paper will describe how Electro Optic Systems has utilized these technologies in the development of its third generation Robotic Observatory Control System (ROCS). ROCS provides an extremely flexible configuration capability within a control system structure to provide truly autonomous robotic observatory operation including observation scheduling. ROCS was built using Internet technologies such as Java, Java Messaging Service (JMS), Lightweight Directory Access Protocol (LDAP), Secure Sockets Layer (SSL), eXtendible Markup Language (XML), Hypertext Transport Protocol (HTTP) and Java WebStart. ROCS was designed to be capable of controlling all aspects of an observatory and be able to be reconfigured to handle changing equipment configurations or user requirements without the need for an expert computer programmer. ROCS consists of many small components, each designed to perform a specific task, with the configuration of the system specified using a simple meta language. The use of small components facilitates testing and makes it possible to prove that the system is correct.

  18. How health plans, health systems, and others in the private sector can stimulate 'meaningful use'.

    PubMed

    Jain, Sachin H; Seidman, Joshua; Blumenthal, David

    2010-09-01

    Provisions of the American Recovery and Reinvestment Act authorize incentive payments to hospitals and clinicians who become "meaningful users" of health information technology (IT). We argue that various private-sector entities--commercial payers, employers, consumer groups, health care ratings organizations, large provider organizations, and regulatory bodies--can further accelerate health IT adoption by implementing strategies that are complementary to the Medicare and Medicaid incentive programs. This paper describes these strategies and potential approaches to implementation.

  20. Internet-based surveillance systems for monitoring emerging infectious diseases.

    PubMed

    Milinovich, Gabriel J; Williams, Gail M; Clements, Archie C A; Hu, Wenbiao

    2014-02-01

    Emerging infectious diseases present a complex challenge to public health officials and governments; these challenges have been compounded by rapidly shifting patterns of human behaviour and globalisation. The increase in emerging infectious diseases has led to calls for new technologies and approaches for detection, tracking, reporting, and response. Internet-based surveillance systems offer a novel and developing means of monitoring conditions of public health concern, including emerging infectious diseases. We review studies that have exploited internet use and search trends to monitor two such diseases: influenza and dengue. Internet-based surveillance systems have good congruence with traditional surveillance approaches. Additionally, internet-based approaches are logistically and economically appealing. However, they do not have the capacity to replace traditional surveillance systems; they should not be viewed as an alternative, but rather an extension. Future research should focus on using data generated through internet-based surveillance and response systems to bolster the capacity of traditional surveillance systems for emerging infectious diseases.

  6. Making a meaningful impact: modelling simultaneous frictional collisions in spatial multibody systems

    PubMed Central

    Uchida, Thomas K.; Sherman, Michael A.; Delp, Scott L.

    2015-01-01

    Impacts are instantaneous, computationally efficient approximations of collisions. Current impact models sacrifice important physical principles to achieve that efficiency, yielding qualitative and quantitative errors when applied to simultaneous impacts in spatial multibody systems. We present a new impact model that produces behaviour similar to that of a detailed compliant contact model, while retaining the efficiency of an instantaneous method. In our model, time and configuration are fixed, but the impact is resolved into distinct compression and expansion phases, themselves comprising sliding and rolling intervals. A constrained optimization problem is solved for each interval to compute incremental impulses while respecting physical laws and principles of contact mechanics. We present the mathematical model, algorithms for its practical implementation, and examples that demonstrate its effectiveness. In collisions involving materials of various stiffnesses, our model can be more than 20 times faster than integrating through the collision using a compliant contact model. This work extends the use of instantaneous impact models to scientific and engineering applications with strict accuracy requirements, where compliant contact models would otherwise be required. An open-source implementation is available in Simbody, a C++ multibody dynamics library widely used in biomechanical and robotic applications. PMID:27547093

  7. Toward an ecologically meaningful view of resource stoichiometry in DOM-dominated aquatic systems

    PubMed Central

    Berggren, Martin; Sponseller, Ryan A.; Alves Soares, Ana R.; Bergström, Ann-Kristin

    2015-01-01

    Research on nutrient controls of planktonic productivity tends to focus on a few standard fractions of inorganic or total nitrogen (N) and phosphorus (P). However, there is a wide range in the degree to which land-derived dissolved organic nutrients can be assimilated by biota. Thus, in systems where such fractions form a majority of the macronutrient resource pool, including many boreal inland waters and estuaries, our understanding of bacterio- and phytoplankton production dynamics remains limited. To adequately predict aquatic productivity in a changing environment, improved standard methods are needed for determining the sizes of active (bioavailable) pools of N, P and organic carbon (C). A synthesis of current knowledge suggests that variation in the C:N:P stoichiometry of bioavailable resources is associated with diverse processes that differentially influence the individual elements across space and time. Due to a generally increasing organic nutrient bioavailability from C to N to P, we hypothesize that the C:N and N:P of bulk resources often vastly overestimates the corresponding ratios of bioavailable resources. It is further proposed that basal planktonic production is regulated by variation in the source, magnitude and timing of terrestrial runoff, through processes that have so far been poorly described.

    Chamberlain, James; Myers, Gerry; Clem, David; Speir, Terri

    2005-01-01

    The Internet Voice Distribution System (IVoDS) is a voice-communication system that comprises mainly computer hardware and software. The IVoDS was developed to supplement and eventually replace the Enhanced Voice Distribution System (EVoDS), which, heretofore, has constituted the terrestrial subsystem of a system for voice communications among crewmembers of the International Space Station (ISS), workers at the Payloads Operations Center at Marshall Space Flight Center, principal investigators at diverse locations who are responsible for specific payloads, and others. The IVoDS utilizes a communication infrastructure of NASA and NASArelated intranets in addition to, as its name suggests, the Internet. Whereas the EVoDS utilizes traditional circuitswitched telephony, the IVoDS is a packet-data system that utilizes a voice over Internet protocol (VOIP). Relative to the EVoDS, the IVoDS offers advantages of greater flexibility and lower cost for expansion and reconfiguration. The IVoDS is an extended version of a commercial Internet-based voice conferencing system that enables each user to participate in only one conference at a time. In the IVoDS, a user can receive audio from as many as eight conferences simultaneously while sending audio to one of them. The IVoDS also incorporates administrative controls, beyond those of the commercial system, that provide greater security and control of the capabilities and authorizations for talking and listening afforded to each user.

    2016-01-01

    Based on the relative theories of quality resource management system and "Internet +", this paper combines the "Internet +"and quality resource management system. By using quality management process approach and taking computers and databases technology as tools, the system collects, archives and manages the quality data in process network, to supervise and control the process of the quality resource management system more effectively. Based on the quality control process in production site and the characteristics of the process, the paper constructs the frame of the resource management system. By taking the STM32F103 series microcontroller as core controller, the system achieves a network system and collects data automatically. The results show that the system can be positioning problem accurately timely and improves the productivity and quality of products.

    1998-01-01

    We have developed a still-image telemedicine system for the Internet. It was implemented with the Java programming language and enables remote collaboration between two or more client computers located anywhere on the Internet. Each client requires only a PC or workstation and a popular Internet browser--no special hardware or software is required. We carried out both local-area and wide-area tests of the system. On a local network, JPEG images at a resolution of 640 x 480 pixels took 2-5 s to display on four different clients (PCs or workstations); at 1000 x 1000 pixels, the images took 10-65 s. We also tested the system between two universities in Japan, one in Italy and one in the USA, using the Internet for communications. Images required 4-20 s for display. The exchange of remote collaboration commands between the four locations was good and the maximum lag in mouse pointer movement was less than 1 s. The system has the potential to solve three problems of conventional telemedicine systems: their cost, the need for high-bandwidth telecommunication and the low compatibility between them.

  13. Acceptance of Internet Banking Systems among Young Managers

    2013-06-01

    The aim of this paper is to determine acceptance of internet banking system among potential young users, specifically future young managers. The relationships and the effects of computer self-efficacy (CSE) and extended technology acceptance model (TAM) on the behavioural intention (BI) to use internet banking system were examined. Measurement of CSE, TAM and BI were adapted from previous studies. However construct for TAM has been extended by adding a new variable which is perceived credibility (PC). A survey through questionnaire was conducted to determine the acceptance level of CSE, TAM and BI. Data were obtained from 275 Technology Management students, who are pursuing their undergraduate studies in a Malaysia's public university. The confirmatory factor analysis performed has identified four variables as determinant factors of internet banking acceptance. The first variable is computer self-efficacy (CSE), and another three variables from TAM constructs which are perceived usefulness (PU), perceived ease of use (PE) and perceived credibility (PC). The finding of this study indicated that CSE has a positive effect on PU and PE of the Internet banking systems. Respondents' CSE was positively affecting their PC of the systems, indicating that the higher the ability of one in computer skills, the higher the security and privacy issues of PC will be concerned. The multiple regression analysis indicated that only two construct of TAM; PU and PC were significantly associated with BI. It was found that the future managers' CSE indirectly affects their BI to use the internet banking systems through PU and PC of TAM. TAM was found to have direct effects on respondents' BI to use the systems. Both CSE and the PU and PC of TAM were good predictors in understanding individual responses to information technology. The role of PE of the original TAM to predict the attitude of users towards the use of information technology systems was surprisingly insignificant.

    This paper describes Web-Altairis, an Internet-enabled ground system software package funded by the Advanced Automation and Architectures Branch (Code 588) of NASA's Goddard Space Flight Center. Web-Altairis supports the trend towards "lights out" ground systems, where the control center is unattended and problems are resolved by remote operators. This client/server software runs on most popular platforms and provides for remote data visualization using the rich functionality of the VisAGE toolkit. Web-Altairis also supports satellite commanding over the Internet. This paper describes the structure of Web-Altairis and VisAGE, the underlying technologies, the provisions for security, and our experiences in developing and testing the software.

    An increasing trend in EMR/EHR system use among office-based physicians was noted from 2001 through preliminary 2011 estimates. In 2011, the NAMCS mail survey showed about 57% of office-based physicians used any EMR/EHR system, a 12% increase from the 2010 estimate. Between 2010 and 2011, the percentage of physicians who reported having systems meeting the criteria for a basic system increased 36%. Adoption of EMR/EHR systems varied greatly by state. In 2011, the percentage of physicians using any EMR/EHR system ranged from 40% in Louisiana to 84% in North Dakota. Compared with the national average, 3 states had a significantly lower percentage of office-based physicians using any EMR/EHR system, and 11 states had a significantly higher percentage. The percentage of physicians having a system that met the criteria for a basic system ranged from 16% in New Jersey to 61% in Minnesota. Compared with the national average, six states had a significantly lower percentage of office-based physicians with a basic system, and eight states had a significantly higher percentage. In 2011, 52% of physicians reported intending to apply for the Medicare or Medicaid EHR incentive payments, a 26% increase from 2010. In 2010, interest among physicians in applying for meaningful use incentive payments was similar to the national average (41%) across most states. In only four states (Alaska, New York, North Dakota, and West Virginia) and the District of Columbia was the percentage lower than the national average. To qualify for Stage 1 meaningful use incentive payments, eligible physicians need to meet all 15 Stage 1 Core Set objectives and 5 of 10 Menu Set objectives, using certified EHR systems (see "Definitions"). In this report, estimates of physicians’ readiness to meet Stage 1 Core Set meaningful use measures were limited to data collected on the computerized functions needed to meet eight Stage 1 objectives. A previous study found that 15% of physicians eligible to apply for

    2001-01-01

    A system has been designed with the aim of helping the communication between a produce of holographic stereograms and users of 3D computer graphics. The user of the system communicates with the producer through a small program, an applet, which is transferred over the Internet. In the applet the user makes all settings necessary for producing the hologram, and then sends the 3D file together with its settings to a holographic printer for production of the hologram. The system uses virtual reality modeling language as an interchangeable graphics format and Java as programming language. It is believed that the system will significantly improve the dissemination of holographic hard copies to ordinary users of computer graphics.

    1991-01-01

    Jade is a new distribution file system that provides a uniform way to name and access files in an internet environment. It makes two important contributions. First, Jade is a logical system that integrates a heterogeneous collection of existing file systems, where heterogeneous means that the underlying file systems support different file access protocols. Jade is designed under the restriction that the underlying file system may not be modified. Second, rather than providing a global name space, Jade permits each user to define a private name space. These private name spaces support two novel features: they allow multiple file systems to be mounted under one directory, and they allow one logical name space to mount other logical name spaces. A prototype of the Jade File System was implemented on Sun Workstations running Unix. It consists of interfaces to the Unix file system, the Sun Network File System, the Andrew File System, and FTP. This paper motivates Jade's design, highlights several aspects of its implementation, and illustrates applications that can take advantage of its features.

    One of the Russian Federal аgency of mineral resources problems is to provide the geological information which was delivered during the field operation for the means of federal budget. This information should be present in the current, conditional form. Before, the leading way of presenting geological information were paper geological maps, slices, borehole diagrams reports etc. Technologies of database construction, including distributed databases, technologies of construction of distributed information-analytical systems and Internet-technologies are intensively developing nowadays. Most of geological organizations create their own information systems without any possibility of integration into other systems of the same orientation. In 2012, specialists of VNIIgeosystem together with specialists of VSEGEI started the large project - creating the system of providing digital geological materials with using modern and perspective internet-technologies. The system is based on the web-server and the set of special programs, which allows users to efficiently get rasterized and vectorised geological materials. These materials are: geological maps of scale 1:1M, geological maps of scale 1:200 000 and 1:2 500 000, the fragments of seamless geological 1:1M maps, structural zoning maps inside the seamless fragments, the legends for State geological maps 1:200 000 and 1:1 000 000, full author's set of maps and also current materials for international projects «Atlas of geological maps for Circumpolar Arctic scale 1:5 000 000» and «Atlas of Geologic maps of central Asia and adjacent areas scale 1:2 500 000». The most interesting and functional block of the system - is the block of providing structured and well-formalized geological vector materials, based on Gosgeolkart database (NGKIS), managed by Oracle and the Internet-access is supported by web-subsystem NGKIS, which is currently based on MGS-Framework platform, developed by VNIIgeosystem.

  6. Extended Darknet: Multi-Dimensional Internet Threat Monitoring System

    NASA Astrophysics Data System (ADS)

    Shimoda, Akihiro; Mori, Tatsuya; Goto, Shigeki

    Internet threats caused by botnets/worms are one of the most important security issues to be addressed. Darknet, also called a dark IP address space, is one of the best solutions for monitoring anomalous packets sent by malicious software. However, since darknet is deployed only on an inactive IP address space, it is an inefficient way for monitoring a working network that has a considerable number of active IP addresses. The present paper addresses this problem. We propose a scalable, light-weight malicious packet monitoring system based on a multi-dimensional IP/port analysis. Our system significantly extends the monitoring scope of darknet. In order to extend the capacity of darknet, our approach leverages the active IP address space without affecting legitimate traffic. Multi-dimensional monitoring enables the monitoring of TCP ports with firewalls enabled on each of the IP addresses. We focus on delays of TCP syn/ack responses in the traffic. We locate syn/ack delayed packets and forward them to sensors or honeypots for further analysis. We also propose a policy-based flow classification and forwarding mechanism and develop a prototype of a monitoring system that implements our proposed architecture. We deploy our system on a campus network and perform several experiments for the evaluation of our system. We verify that our system can cover 89% of the IP addresses while darknet-based monitoring only covers 46%. On our campus network, our system monitors twice as many IP addresses as darknet.

    Allergic rhinitis (AR) results from a complex allergen-driven mucosal inflammation in the nasal cavity. Current guideline-based therapy for allergic rhinitis include oral and nasal antihistamines, topical and systemic glucocorticoids, decongestants, antimuscarinic agents, mast cell stabilizing drugs, leukotriene-receptor antagonists, and others. In spite of guideline recommendations, most patients are using multiple therapies in an attempt to achieve symptom control. Therefore, more effective therapies for the management of AR are clearly required. Recently, a novel fixed dose combination containing azelastine and fluticasone propionate has successfully been introduced. At present, it represents the only meaningful topical drug combination. Perhaps, it will be followed by others. PMID:24974572

    Internet Of Things (IOT) drives a significant increase in the extent and type of sensing technology and equipment. Sensors, instrumentation, control electronics, data logging and transmission units comprising such sensing systems will all require to be powered. Conventionally, electrical powering is supplied by batteries or/and electric power cables. The power supply by batteries usually has a limited lifetime, while the electric power cables are susceptible to electromagnetic interference. In fact, the electromagnetic interference is the key issue limiting the power supply in the strong electromagnetic radiation area and other extreme environments. The novel alternative method of power supply is power over fiber (PoF) technique. As fibers are used as power supply lines instead, the delivery of the power is inherently immune to electromagnetic radiation, and avoids cumbersome shielding of power lines. Such a safer power supply mode would be a promising candidate for applications in IOT. In this work, we built up optically powered active sensing system, supplying uninterrupted power for the remote active sensors and communication modules. Also, we proposed a novel maximum power point tracking technique for photovoltaic power convertors. In our system, the actual output efficiency greater than 40% within 1W laser power. After 1km fiber transmission and opto-electric power conversion, a stable electric power of 210mW was obtained, which is sufficient for operating an active sensing system.

    2016-05-01

    In this paper some of the motivations for energy-efficient communications in wireless systems are described by highlighting emerging trends and identifying some challenges that need to be addressed to enable novel, scalable and energy-efficient communications. So an architecture for Internet of Things systems is presented, the purpose of which is to minimize energy consumption by communication devices, protocols, networks, end-user systems and data centers. Some electrical devices have been designed with multiple communication interfaces, such as RF or WiFi, using open source technology; they have been analyzed under different working conditions. Some devices are programmed to communicate directly with a web server, others to communicate only with a special device that acts as a bridge between some devices and the web server. Communication parameters and device status have been changed dynamically according to different scenarios in order to have the most benefits in terms of energy cost and battery lifetime. So the way devices communicate with the web server or between each other and the way they try to obtain the information they need to be always up to date change dynamically in order to guarantee always the lowest energy consumption, a long lasting battery lifetime, the fastest responses and feedbacks and the best quality of service and communication for end users and inner devices of the system.

    In this work that is being validated within the VEPSY project, we present a system that allows the patient to continue a psychological virtual reality treatment from his or her home PC as complementary therapy. In the consulting room, we have been using virtual therapy for panic disorder and agoraphobia treatment to expose the patient to several situations. For the complementary therapy, a structured treatment via the Internet has been prepared, which consists of several parts: an assessment protocol; a structured treatment protocol organized in several blocks (such as psychoeducation and exposure); and an outcome protocol. The same situations as in the consulting room have been selected for the exposure, but each of them has been divided into several virtual environments with specific characteristics that limit its difficulty level. The stimuli that are used at each level are controlled automatically by the system. The information of the patient is stored in a database, which is placed in a remote server using XML format and used to control which stages of the treatment he or she can access. The psychologist can limit the evolution of the patient. The virtual environments are installed in the patient's PC, and they are implemented with a mechanism that ensures that they can only be run when the patient connects to the web. The user should not have any special virtual reality hardware at home, so head rotations have been simulated with the navigation system.

    The present review considers a series of studies of noise conducted in collaboration with Dr. Michel Loeb. This review attempts to provide a theoretical perspective as well as to summarize the most important findings of those studies. The work reviewed shows that noise effects interact with other variables, such that a noise effect on one sex is reversed for the other, and is also reversed at different times of the day. A second experiment confirmed this finding with a different arithmetic task. Further work indicated parallels between noise and fatigue, with aftereffects depending upon both work and noise. The final experiment repeated some of these findings with a different task battery of information processing tasks while showing that noise effects further depend on the meaningfulness of the noise background.

    ARTEMIS is one of the first systems to exploit the Internet/Intranet technologies for exchanging patient information among health care providers. The primary project goal was to develop and demonstrate a regional telehealth environment specifically to support real-time consultations among health care providers via a computer network, provide secure access to multi-media patient records and discharge summaries, facilitate authentication/digital sign-off, multi-media mail-based referrals, and network-based dictation/transcription. A prototype is deployed in southern West Virginia in a Community Care Network (CCN). The CCN consists of providers, hospitals, clinics, laboratories, that make up one "Virtual" clinic on the "Intranet". ARTEMIS employs new technologies such as Java and JavaScript for the browser, and CORBA-based "middleware" for interoperability at the server-end. Several experiments were designed for evaluating the impact of ARTEMIS on patient care. In this paper we discuss the challenges we faced and the means by which we plan to meet these challenges. We conclude by outlining new thrust areas in which we are concentrating in our next phase of development of ARTEMIS. PMID:9357727

    Reaccreditation is a well-accepted fact for many doctors outside the United Kingdom and is likely to become a reality for British general practitioners. The author'sabbatical year in the United States of America studying reaccreditation and its relationship to continuing medical education has enabled a critical analysis of recent proposals in the UK to be carried out. The aim of reaccreditation must be understood by the profession and must be clearly stated. To be credible it will have to be mandatory and linked to continuing medical education. Current types of continuing medical education must be developed so that they are meaningful, influence doctors' behaviour and include research, audit, training, reading and medical writing. The profession must confront the need to penalize the small number of doctors who have an unacceptable standard of practice. The potential benefits of an appropriate form of reaccreditation may include improved quality of care and patient outcome, enhanced job satisfaction and reduced rates of burnout. PMID:7619590

    We have developed an external storage system by using secret sharing scheme and tokenization for regional medical cooperation, PHR service and information preservation. The use of mobile devices such as smart phones and tablets will be accelerated for a PHR service, and the confidential medical information is exposed to the risk of damage and intercept. We verified the transfer rate of the sending and receiving of data to and from the external storage system that connected it with PACS by the Internet this time. External storage systems are the data centers that exist in Okinawa, in Osaka, in Sapporo and in Tokyo by using secret sharing scheme. PACS continuously transmitted 382 CT images to the external data centers. Total capacity of the CT images is about 200MB. The total time that had been required to transmit was about 250 seconds. Because the preservation method to use secret sharing scheme is applied, security is strong. But, it also takes the information transfer time of this system too much. Therefore, DICOM data is masked to the header information part because it is made to anonymity in our method. The DICOM data made anonymous is preserved in the data base in the hospital. Header information including individual information is divided into two or more tallies by secret sharing scheme, and preserved at two or more external data centers. The token to relate the DICOM data anonymity made to header information preserved outside is strictly preserved in the token server. The capacity of header information that contains patient's individual information is only about 2% of the entire DICOM data. This total time that had been required to transmit was about 5 seconds. Other, common solutions that can protect computer communication networks from attacks are classified as cryptographic techniques or authentication techniques.

    The Internet consists of a vast inhomogeneous reservoir of data. Developing software that can integrate a wide variety of different data sources is a major challenge that must be addressed for the realisation of the full potential of the Internet as a scientific research tool. This article presents a semi-automated object-oriented programming system for integrating web-based resources. We demonstrate that the current Internet standards (HTML, CGI [common gateway interface], Java, etc.) can be exploited to develop a data retrieval system that scans existing web interfaces and then uses a set of rules to generate new Java code that can automatically retrieve data from the Web. The validity of the software has been demonstrated by testing it on several biological databases. We also examine the current limitations of the Internet and discuss the need for the development of universal standards for web-based data.

    To compare the benefits of the Internet generally versus a focused system of services, 257 breast cancer patients were randomly assigned to a control group, access to the Internet with links to high-quality breast cancer sites, or access to an eHealth system (Comprehensive Health Enhancement Support System, CHESS) that integrated information, support, and decision and analysis tools. The intervention lasted 5 months, and self-report data on quality of life, health-care competence, and social support were collected at pretest and at 2-, 4-, and 9-month posttests. CHESS subjects logged on more overall than Internet subjects and accessed more health resources, but the latter used non health-related sites more. Subjects with access to the Internet alone experienced no better outcomes than controls at any of the 3 time points, compared to pretest levels. Subjects with CHESS experienced greater social support during the intervention period and had higher scores on all 3 outcomes at 9 months, 4 months after the intervention ended. CHESS subjects also scored higher than those with Internet access during the intervention period but not significantly after the intervention ended. Thus, CHESS (with one simple interface and integrated information, communication, and skills services) helped newly diagnosed breast cancer patients even after computers were removed. In contrast, patients received little benefit from Internet access, despite having links to a variety of high-quality sites. PMID:21804645

  2. Security threat assessment of an Internet security system using attack tree and vague sets.

    PubMed

    2014-01-01

    Security threat assessment of the Internet security system has become a greater concern in recent years because of the progress and diversification of information technology. Traditionally, the failure probabilities of bottom events of an Internet security system are treated as exact values when the failure probability of the entire system is estimated. However, security threat assessment when the malfunction data of the system's elementary event are incomplete--the traditional approach for calculating reliability--is no longer applicable. Moreover, it does not consider the failure probability of the bottom events suffered in the attack, which may bias conclusions. In order to effectively solve the problem above, this paper proposes a novel technique, integrating attack tree and vague sets for security threat assessment. For verification of the proposed approach, a numerical example of an Internet security system security threat assessment is adopted in this paper. The result of the proposed method is compared with the listing approaches of security threat assessment methods.

    A few years ago, real time communication, data collection and transmission from a field station measuring electromagnetic variations in the middle of nowhere, was a very expensive accomplishment. Nowadays, wireless communications and Internet access reach end users much easier and they are less expensive. WIFI, GPRS, 3G or Satellite Internet connections enable this to come true even at the most detached areas of our world where no cables can easily reach at a low cost. Except for the effective potential range, these communication technologies can also give high speed, constant and low cost Internet access. As the Internet access speeds grow, a new term is coming to the foreground. Cloud Computing. The terminology of Cloud Computing refers to a wide subset of Internet technologies usage that the clients: A)Do not need to store any valuable information in any physical infrastructure owned by themselves. B)Consume on-line resources from a third party provider, enabling them to focus on their productivity without having to worry about their data or any other possible local hardware failure. C)Collaborate and share between associates faster and easier, as they can access their work from anywhere, just with the existence of Internet access. This telemetric system, relies on Cloud Computing for the delivery of collected data from the field station to an on-line storage. Collaborators and scientists, can be synchronized with the on-line storage, make changes and synchronize vice versa. Local storage at the field station end, is only needed in the case of an Internet connection failure, so that the data can be stored until the Internet connection is regained. Local storage at the user's side is optional, however desirable thus giving the ability to work off-line and synchronize again the changes when one goes on-line.

    1997-12-31

    The eight Great Lakes states, the Canadian province of Ontario and the Great Lakes Commission are involved in a collective effort to develop a regional inventory of toxic air emissions for 49 targeted toxic pollutants from point and area sources. The regional inventory will soon be expanded to include emissions from mobile sources. The inventory, when aggregated for all eight states and Ontario, will eventually reside at the US Environmental Protection Agency (EPA), Great Lakes National Program Office (GLNPO). To aid in the understanding and interpretation of the inventory`s data, an effort has been undertaken to generate two map series for the entire region: (1) choropleth maps of total toxic air emissions at the county level of geography and (2) dot maps showing facility locations. To ensure an effective and efficient dissemination process among the province and various states, an interactive Internet mapping interface prototype was modified and used for the project. With an interactive online visualization tool, the inventory collectors, managers and researchers can quickly and effectively view the inventory`s data on maps, charts or spreadsheets. These graphics can be used as: (1) a QA/QC function for the inventory collectors, (2) a simple communication of complex data to support managers decision making and (3) a means for easy access to complex data and information about any geographic area in the region for the researchers or general public. This paper describes the development and use of PC Arc/Info, ArcView and MapInfo geographic information systems (GIS), mapping and Internet interfacing applications to visualize, disseminate and convey the emissions inventory data in a meaningful and useful manner. The various methods developed and implemented to convert, process and prepare the inventory data and Internet interface for use with a standard Internet web browser also are described in this paper.

    Spontaneous combustion on industrial-scale stockpiles causes environmental problems and economic losses for the companies consuming large amounts of coal. In this study, an effective monitoring and prediction system based on internet was developed and implemented to prevent losses and environmental problems. The system was performed in a coal stockpile with 5 m width, 10 m length, 3 m height, and having 120 t of weight. The inner temperature data of the stockpile was recorded by 17 temperature sensors placed inside the stockpile at certain points. Additionally, the data relating to the air temperature, air humidity, atmospheric pressure, wind velocity, and wind direction that are the parameters affecting the coal stockpile were also recorded. The recorded values were analyzed with artificial neural network and Statistical modeling methods for prediction of spontaneous combustion. Real-time measurement values and model outputs were published with a web page on internet. The internet-based system can also provide real-time monitoring (combustion alarms, system status) and tele-controlling (Parameter adjusting, system control) through internet exclusively with a standard web browser without the need of any additional software.

    The VitalPoll Telemedicine System (VTS) was designed and developed for wireless home healthcare. The aims of this study were: to design the architecture and communication methods for a telemedicine system; to implement a physiologic routing hub to collect data from different medical devices and sensors; and to evaluate the feasibility of this system for applications in wireless home healthcare. The VTS was built using Bluetooth wireless and Internet technologies with client/server architecture. Several medical devices, which acquire vital signs, such as real-time electrocardiogram signals, heart rate, body temperature, and activity (physical motion), were integrated into the VTS. Medical information and data were transmitted over short-range interface (USB, RS232), wireless communication, and the Internet. The medical results were stored in a database and presented using a web browser. The patient's vital signals can be collected, transmitted, and displayed in real time by the VTS. The experiments verified no data loss during Bluetooth and Internet communication. Bluetooth and the Internet provide enough bandwidth channels to tranmit these vital signs. The experimental results show that VTS may be suitable for a practical telemedicine system in home healthcare.

  1. Birth, meaningful viability and abortion.

    PubMed

    Jensen, David

    2015-06-01

    What role does birth play in the debate about elective abortion? Does the wrongness of infanticide imply the wrongness of late-term abortion? In this paper, I argue that the same or similar factors that make birth morally significant with regard to abortion make meaningful viability morally significant due to the relatively arbitrary time of birth. I do this by considering the positions of Mary Anne Warren and José Luis Bermúdez who argue that birth is significant enough that the wrongness of infanticide does not imply the wrongness of late-term abortion. On the basis of the relatively arbitrary timing of birth, I argue that meaningful viability is the point at which elective abortion is prima facie morally wrong.

    A prototype has been developed which makes use of commercially available products in conjunction with the Java programming language to provide a secure user interface for command and control over the open Internet. This paper reports successful demonstration of: (1) Security over the Internet, including encryption and certification; (2) Integration of Java applets with a COTS command and control product; (3) Remote spacecraft commanding using the Internet. The Java-based Spacecraft Web Interface to Telemetry and Command Handling (Jswitch) ground system prototype provides these capabilities. This activity demonstrates the use and integration of current technologies to enable a spacecraft engineer or flight operator to monitor and control a spacecraft from a user interface communicating over the open Internet using standard World Wide Web (WWW) protocols and commercial off-the-shelf (COTS) products. The core command and control functions are provided by the COTS Epoch 2000 product. The standard WWW tools and browsers are used in conjunction with the Java programming technology. Security is provided with the current encryption and certification technology. This system prototype is a step in the direction of giving scientist and flight operators Web-based access to instrument, payload, and spacecraft data.

    Implementing capabilities on the World Wide Web should never be taken lightly. A good systems engineer is able to examine such implementations from all points of view, including political, legal, security, access, technical deployment, and quality. The evacuation discussed in this paper was conducted to ensure that the National Aeronautics and Space Administration (NASA) was proceeding in a correct direction by implementing RECALL a Lessons Learned System on the Web and, subsequently, did so successfully. The systems approach extended well beyond technical implementation to several issue that are not often addressed by an implementation team. The resulting evaluation increased the team's sensitivity to such issues and, in fact, the authors believe that the evaluation provided as much benefit as the system itself.

    Due to limited crew availability to support science and the large number of experiments to be operated simultaneously, telescience is key to a successful International Space Station (ISS) science program. Crew, operations personnel at NASA centers, and researchers at universities and companies around the world must work closely together to perform scientific experiments on-board ISS. NASA has initiated use of Voice over Internet Protocol (VoIP) to supplement the existing HVoDS mission voice communications system used by researchers. The Internet Voice Distribution System (IVoDS) connects researchers to mission support "loops" or conferences via Internet Protocol networks such as the high-speed Internet 2. Researchers use IVoDS software on personal computers to talk with operations personnel at NASA centers. IVoDS also has the capability, if authorized, to allow researchers to communicate with the ISS crew during experiment operations. NODS was developed by Marshall Space Flight Center with contractors A2 Technology, Inc. FVC, Lockheed- Martin, and VoIP Group. IVoDS is currently undergoing field-testing with full deployment for up to 50 simultaneous users expected in 2002. Research is currently being performed to take full advantage of the digital world - the Personal Computer and Internet Protocol networks - to qualitatively enhance communications among ISS operations personnel. In addition to the current voice capability, video and data-sharing capabilities are being investigated. Major obstacles being addressed include network bandwidth capacity and strict security requirements. Techniques being investigated to reduce and overcome these obstacles include emerging audio-video protocols and network technology including multicast and quality-of-service.

    PubMed Central

    2014-01-01

    Security threat assessment of the Internet security system has become a greater concern in recent years because of the progress and diversification of information technology. Traditionally, the failure probabilities of bottom events of an Internet security system are treated as exact values when the failure probability of the entire system is estimated. However, security threat assessment when the malfunction data of the system's elementary event are incomplete—the traditional approach for calculating reliability—is no longer applicable. Moreover, it does not consider the failure probability of the bottom events suffered in the attack, which may bias conclusions. In order to effectively solve the problem above, this paper proposes a novel technique, integrating attack tree and vague sets for security threat assessment. For verification of the proposed approach, a numerical example of an Internet security system security threat assessment is adopted in this paper. The result of the proposed method is compared with the listing approaches of security threat assessment methods. PMID:25405226

    2003-12-01

    The Polar Radar for Ice Sheet Measurements (PRISM) Project at the University of Kansas has developed and field-tested a versatile communications system for use by researchers in high-latitude Polar Regions. The PRISM project is developing advanced intelligent remote sensing technology that involves radar systems, an autonomous rover, and communications systems to measure detailed ice sheet characteristics, and to determine bed conditions (frozen or wet) below active ice sheets in both Greenland and Antarctica. We also have a very strong public outreach and educational program aimed at K-12 educators and students that requires data, voice and video feeds from Polar field locations in near real time. Hence, PRISM requires a robust communications system for use in the field between a base camp and the mobile remote sensing system, and from the field back to the University of Kansas and onto the Internet. The communication system that has been developed is truly mobile and is relatively inexpensive. We initially considered various satellite services during the design phase of this project. The two feasible options for high-latitude locations were Iridium, with its low-bit-rate service (2.4 Kb/s), and Inmarsat/Intelsat with broadband service. We selected the Iridium option for testing and development because it provided coverage in both Antarctica and Greenland. To achieve higher capacity communications, the multilink point-to-point protocol (MLPPP) implemented in Linux was tuned to operate efficiently over the Iridium satellite system. This mechanism combines multiple channels to obtain a seamless data connection with a capacity equal to the sum of the individual link rates. We used four Iridium modems to obtain an aggregate capacity of about 9.6 Kb/s. Standard Internet protocols (TCP/IP) were then used to provide end-to-end connectivity. The communications system field experiments were conducted at the NorthGRIP ice core drilling camp in Greenland (75° 06' N, 42° 20

    2011-01-01

    While many attacks are distributed across botnets, investigators and network operators have recently targeted malicious networks through high profile autonomous system (AS) de-peerings and network shut-downs. In this paper, we explore whether some ASes indeed are safe havens for malicious activity. We look for ISPs and ASes that exhibit disproportionately high malicious behavior using ten popular blacklists, plus local spam data, and extensive DNS resolutions based on the contents of the blacklists. We find that some ASes have over 80% of their routable IP address space blacklisted. Yet others account for large fractions of blacklisted IP addresses. Several ASes regularly peer with ASes associated with significant malicious activity. We also find that malicious ASes as a whole differ from benign ones in other properties not obviously related to their malicious activities, such as more frequent connectivity changes with their BGP peers. Overall, we conclude that examining malicious activity at AS granularity can unearth networks with lax security or those that harbor cybercrime.

    Over low-bit-rate network such as the Internet, a video service has problems of video representation delay and degradation of QoS because it cannot transmit video data within restricted time. Data compression and transmission techniques have been researched for solving this problems. In this paper, we represent a new real-time VoD service system on the Internet. This VoD which is based on the client/server architecture has been developed using ITU-T H.263 video codec which has high compression ratio and good quality of video data and 8.3kpbs Truespeech audio codec. Our system can provide a real-time video service according to user demand on the Web browser, and support a tool to generate video streams stored at the video server. In this system, for solving the problems of the real-time VoD service over the Internet, we propose new techniques of buffer control to guaranteed audio/video QoS, synchronization between audio and video, video summary service by use of scene change detection, and etc.

  1. Concept Mapping Using Cmap Tools to Enhance Meaningful Learning

    NASA Astrophysics Data System (ADS)

    Cañas, Alberto J.; Novak, Joseph D.

    Concept maps are graphical tools that have been used in all facets of education and training for organizing and representing knowledge. When learners build concept maps, meaningful learning is facilitated. Computer-based concept mapping software such as CmapTools have further extended the use of concept mapping and greatly enhanced the potential of the tool, facilitating the implementation of a concept map-centered learning environment. In this chapter, we briefly present concept mapping and its theoretical foundation, and illustrate how it can lead to an improved learning environment when it is combined with CmapTools and the Internet. We present the nationwide “Proyecto Conéctate al Conocimiento” in Panama as an example of how concept mapping, together with technology, can be adopted by hundreds of schools as a means to enhance meaningful learning.

  2. Development of the Internet-Based Customer-Oriented Ordering System Framework for Complicated Mechanical Product

    Ong, Mingwei; Watanuki, Keiichi

    Recently, as consumers gradually prefer buying products that reflect their own personality, there exist some consumers who wish to involve in the product design process. Parallel with the popularization of e-business, many manufacturers have utilized the Internet to promote their products, and some have even built websites that enable consumers to select their desirable product specifications. Nevertheless, this method has not been applied on complicated mechanical product due to the facts that complicated mechanical product has a large number of specifications that inter-relate among one another. In such a case, ordinary consumers who are lacking of design knowledge, are not capable of determining these specifications. In this paper, a prototype framework called Internet-based consumer-oriented product ordering system has been developed in which it enables ordinary consumers to have large freedom in determining complicated mechanical product specifications, and meanwhile ensures that the manufacturing of the determined product is feasible.

  3. Internet Sexualities

    NASA Astrophysics Data System (ADS)

    Döring, Nicola

    The term “internet sexuality” (or OSA, online sexual activities) refers to sexual-related content and activities observable on the internet (cf. Adams, Oye, & Parker, 2003; Cooper, McLoughlin, & Campbell, 2000; Leiblum & Döring, 2002). It designates a variety of sexual phenomena (e.g., pornography, sex education, sexual contacts) related to a wide spectrum of online services and applications (e.g., websites, online chat rooms, peer-to-peer networks). If an even broader range of computer networks - such as the Usenet or bulletin board systems - is included in this extensional definition, one speaks of “online sexuality” or “cybersexuality.”

    With the emergence of the Internet of Things (IoT), a large number of physical objects in daily life have been aggressively connected to the Internet. As the number of objects connected to networks increases, the security systems face a critical challenge due to the global connectivity and accessibility of the IoT. However, it is difficult to adapt traditional security systems to the objects in the IoT, because of their limited computing power and memory size. In light of this, we present a lightweight security system that uses a novel malicious pattern-matching engine. We limit the memory usage of the proposed system in order to make it work on resource-constrained devices. To mitigate performance degradation due to limitations of computation power and memory, we propose two novel techniques, auxiliary shifting and early decision. Through both techniques, we can efficiently reduce the number of matching operations on resource-constrained systems. Experiments and performance analyses show that our proposed system achieves a maximum speedup of 2.14 with an IoT object and provides scalable performance for a large number of patterns.

    The present state of information communication technology makes it possible to devise and run computer-based e-laboratories accessible to any user with a connection to the Internet, equipped with very simple technical means and making full use of web services. Thus, the way is open for a new strategy of physics education with strongly global features, based on experiment and experimentation. We name this strategy integrated e-learning, and remote experiments across the Internet are the foundation for this strategy. We present both pedagogical and technical reasoning for the remote experiments and outline a simple system based on a server-client approach, and on web services and Java applets. We give here an outline of the prospective remote laboratory system with data transfer using the Internet School Experimental System (ISES) as hardware and ISES WEB Control kit as software. This approach enables the simple construction of remote experiments without building any hardware and virtually no programming, using a paste and copy approach with typical prebuilt blocks such as a camera view, controls, graphs, displays, etc. We have set up and operate at present seven experiments, running round the clock, with more than 12 000 connections since 2005. The experiments are widely used in practical teaching of both university and secondary level physics. The recording of the detailed steps the experimentor takes during the measurement enables detailed study of the psychological aspects of running the experiments. The system is ready for a network of universities to start covering the basic set of physics experiments. In conclusion we summarize the results achieved and experiences of using remote experiments built on the ISES hardware system.

    In Australia, drug monitoring systems have been in place for more than a decade allowing for the measurement of ongoing trends in drug use and the detection of new drugs. The Drug Trends Unit at the National Drug and Alcohol Research Centre monitors drugs through four separate systems. The Illicit Drug Reporting System (IDRS) measures the price, purity, and availability of drugs that are primarily injected. The Ecstasy and Related Drugs Reporting System (EDRS) monitors psychostimulants that are used recreationally. The National Illicit Drugs Indicator Project (NIDIP) analyzes indicator data including drug-related hospitalizations and deaths. Finally, the Drugs and Emerging Technologies Project (DNeT) analyzes the role of the Internet in the procurement and use of novel psychoactive substances. This paper provides an overview of each component of the system, demonstrating how the system has evolved over time.

  10. Psychology and death. Meaningful rediscovery.

    Feifel, H

    The place of death in psychology is reviewed historically. Leading causes for its being slighted as an area of investigation during psychology's early years are presented. Reasons for its rediscovery in the mid-1950s as a legitimate sector for scientific inquiry are then discussed, along with some vicissitudes encountered in carrying out research in the field. This is followed by a description of principal empirical findings, clinical perceptions, and perspectives emerging from work in the thanatological realm. The probability that such urgent social issues as abortion, acquired immunodeficiency syndrome (AIDS), and euthanasia, and such destructive behaviors as drug abuse, alcoholism, and certain acts of violence are associated with attitudes toward death offers a challenge to psychology to enhance the vitality of human response to maladaptive conduct and loss. Recognition of personal mortality is a major entryway to self-knowledge. Although death is manifestly too complex to be the special sphere of any one discipline, psychology's position as an arena in which humanist and physicist-engineer cultures intersect provides us with a meaningful opportunity to advance our comprehension of how death can serve life.

    Meaning has been left outside most theoretical approaches to information in biology. Functional responses based on an appropriate interpretation of signals have been replaced by a probabilistic description of correlations between emitted and received symbols. This assumption leads to potential paradoxes, such as the presence of a maximum information associated to a channel that creates completely wrong interpretations of the signals. Game-theoretic models of language evolution and other studies considering embodied communicating agents show that the correct (meaningful) match resulting from agent-agent exchanges is always achieved and natural systems obviously solve the problem correctly. Inspired by the concept of duality of the communicative sign stated by the swiss linguist Ferdinand de Saussure, here we present a complete description of the minimal system necessary to measure the amount of information that is consistently decoded. Several consequences of our developments are investigated, such as the uselessness of a certain amount of information properly transmitted for communication among autonomous agents.

    With the availability of Internet, the interest in the possibilities of telepathology has increased considerably. In the foreground is thereby the need of the non-expert to bring in the opinions of experts on morphological findings by means of a fast and simple procedure. The new telepathology system iPath is in compliance with these needs. The system is based on small, but when possible independently working modules. This concept allows a simple adaptation of the system to the individual environment of the user (e.g. for different cameras, frame-grabbers, microscope steering tables etc.) and for individual needs. iPath has been in use for 6 months with various working groups. In telepathology a distinction is made between "passive" and "active" consultations but for both forms a non-expert brings in the opinion of an expert. In an active consultation both are in direct connection with each other (orally or via a chat-function), this is however not the case with a passive consultation. An active consultation can include the interactive discussion of the expert with the non-expert on images in an image database or the direct interpretation of images from a microscope by the expert. Four software modules are available for a free and as fast as possible application: (1) the module "Microscope control", (2) the module "Connector" (insertion of images directly from the microscope without a motorized microscope), (3) the module "Client-application" via the web-browser and (4) the module "Server" with a database. The server is placed in the internet and not behind a firewall. The server permanently receives information from the periphery and returns the information to the periphery on request. The only thing which the expert, the non-expert and the microscope have to know is how contact can made with the server.

    The visual system needs to extract the most important elements of the external world from a large flux of information in a short time for survival purposes. It is widely believed that in performing this task, it operates a strong data reduction at an early stage, by creating a compact summary of relevant information that can be handled by further levels of processing. In this work we formulate a model of early vision based on a pattern-filtering architecture, partly inspired by high-speed digital data reduction in experimental high-energy physics (HEP). This allows a much stronger data reduction than models based just on redundancy reduction. We show that optimizing this model for best information preservation under tight constraints on computational resources yields surprisingly specific a-priori predictions for the shape of biologically plausible features, and for experimental observations on fast extraction of salient visual features by human observers. Interestingly, applying the same optimized model to HEP data acquisition systems based on pattern-filtering architectures leads to specific a-priori predictions for the relevant data patterns that these devices extract from their inputs. These results suggest that the limitedness of computing resources can play an important role in shaping the nature of perception, by determining what is perceived as "meaningful features" in the input data.

    Modern infrastructure, such as dense urban areas and underground tunnels, can effectively block all GPS signals, which implies that effective position triangulation will not be achieved. The main problem that is addressed in this project is the design and implementation of an accurate vehicle location system using radio-frequency identification (RFID) technology in combination with GPS and the Global system for Mobile communication (GSM) technology, in order to provide a solution to the limitation discussed above. In essence, autonomous vehicle tracking will be facilitated with the use of RFID technology where GPS signals are non-existent. The design of the system and the results are reflected in this paper. An extensive literature study was done on the field known as the Internet of Things, as well as various topics that covered the integration of independent technology in order to address a specific challenge. The proposed system is then designed and implemented. An RFID transponder was successfully designed and a read range of approximately 31 cm was obtained in the low frequency communication range (125 kHz to 134 kHz). The proposed system was designed, implemented, and field tested and it was found that a vehicle could be accurately located and tracked. It is also found that the antenna size of both the RFID reader unit and RFID transponder plays a critical role in the maximum communication range that can be achieved.

An extensive literature study was done on the field known as the Internet of Things, as well as various topics that covered the integration of independent technology in order to address a specific challenge. The proposed system is then designed and implemented. An RFID transponder was successfully designed and a read range of approximately 31 cm was obtained in the low frequency communication range (125 kHz to 134 kHz). The proposed system was designed, implemented, and field tested and it was found that a vehicle could be accurately located and tracked. It is also found that the antenna size of both the RFID reader unit and RFID transponder plays a critical role in the maximum communication range that can be achieved. PMID:27271638

    Although the connection rate is slow, new nuclear utility Internet connections are being made. However, the rate of information exchange has not grown. To expedite connections, individuals are obtaining their own Internet accounts to support job-related and personal needs. The nuclear industry should increase its use of Internet to share information and access information from on-line servers. A coordinated industry effort should be made to expedite additional utility connections and provide a server system for information exchange.

    Urban sprawl and the corresponding land use change from lower intensity uses, such as agriculture and forests, to higher intensity uses including high density residential and commercial has various long- and short-term environment impacts on ground water recharge, water pollution, and storm water drainage. A web-based Spatial Decision Support System, SDSS, for Web-based operation of long-term hydrologic impact modeling and analysis was developed. The system combines a hydrologic model, databases, web-GIS capability and HTML user interfaces to create a comprehensive hydrologic analysis system. The hydrologic model estimates daily direct runoff using the NRCS Curve Number technique and annual nonpoint source pollution loading by an event mean concentration approach. This is supported by a rainfall database with over 30 years of daily rainfall for the continental US. A web-GIS interface and a robust Web-based watershed delineation capability were developed to simplify the spatial data preparation task that is often a barrier to hydrologic model operation. The web-GIS supports browsing of map layers including hydrologic soil groups, roads, counties, streams, lakes and railroads, as well as on-line watershed delineation for any geographic point the user selects with a simple mouse click. The watershed delineation results can also be used to generate data for the hydrologic and water quality models available in the DSS. This system is already being used by city and local government planners for hydrologic impact evaluation of land use change from urbanization, and can be found at http://pasture.ecn.purdue.edu/~watergen/hymaps. This system can assist local community, city and watershed planners, and even professionals when they are examining impacts of land use change on water resources. They can estimate the hydrologic impact of possible land use changes using this system with readily available data supported through the Internet. This system provides a cost effective

    The standard Akta Explorer high-performance liquid chromatography (HPLC) system has limitations for the automation of multidimensional protein purification. Here, we describe simple modifications that allow for automated multidimensional purification protocols to extend the possibilities of the Akta three-dimensional purification kit in terms of column number, flexibility of volumes stocked for re-injection of samples, and available choice of buffers. These modifications do not preclude the use of standard one-dimensional purification protocols. Additionally, we demonstrate a technology for encrypted full remote control of the machine over the Internet by cost-effective use of standard asymmetric digital subscriber line (ADSL) that enables direct remote interaction with the machine without preventing local control. A 4-column purification scheme, including equilibration and cleaning in place (CIP) procedures, was implemented on such a system. It significantly increased reproducibility and shortened processing time by 85%, as compared with manual operation, thus allowing for automated protein purification overnight.

    Introduction Critical care physicians may benefit from immediate access to medical reference material. We evaluated the feasibility and potential benefits of a handheld computer based knowledge access system linking a central academic intensive care unit (ICU) to multiple community-based ICUs. Methods Four community hospital ICUs with 17 physicians participated in this prospective interventional study. Following training in the use of an internet-linked, updateable handheld computer knowledge access system, the physicians used the handheld devices in their clinical environment for a 12-month intervention period. Feasibility of the system was evaluated by tracking use of the handheld computer and by conducting surveys and focus group discussions. Before and after the intervention period, participants underwent simulated patient care scenarios designed to evaluate the information sources they accessed, as well as the speed and quality of their decision making. Participants generated admission orders during each scenario, which were scored by blinded evaluators. Results Ten physicians (59%) used the system regularly, predominantly for nonmedical applications (median 32.8/month, interquartile range [IQR] 28.3–126.8), with medical software accessed less often (median 9/month, IQR 3.7–13.7). Eight out of 13 physicians (62%) who completed the final scenarios chose to use the handheld computer for information access. The median time to access information on the handheld handheld computer was 19 s (IQR 15–40 s). This group exhibited a significant improvement in admission order score as compared with those who used other resources (P = 0.018). Benefits and barriers to use of this technology were identified. Conclusion An updateable handheld computer system is feasible as a means of point-of-care access to medical reference material and may improve clinical decision making. However, during the study, acceptance of the system was variable. Improved training and new

    This chapter reviews efforts of selected standards consortia to develop Internet-based approaches for interoperable manufacturing enterprise information systems. The focus of the chapter is on the efforts to capture common meaning of data exchanged among interoperable information systems inside and outside a manufacturing enterprise. We start this chapter by giving a general overview of the key concepts in standards approaches to enable interoperable manufacturing enterprise systems. These approaches are compared on the basis of several characteristics found in standards frameworks such as horizontal or vertical focus of the standard, the standard message content definitions, the standard process definitions, and dependence on specific standard messaging solutions. After this initial overview, we establish one basis for reasoning about interoperable information systems by recognizing key manufacturing enterprise objects managed and exchanged both inside and outside the enterprise. Such conceptual objects are coarse in granularity and are meant to drive semantic definitions of data interchanges by providing a shared context for data dictionaries detailing the semantics of these objects and interactions or processes involved in data exchange. In the case of intra-enterprise interoperability, we recognize enterprise information processing activities, responsibilities, and those high-level conceptual objects exchanged in interactions among systems to fulfill the assigned responsibilities. Here, we show a mapping of one content standard onto the identified conceptual objects. In the case of inter-enterprise interoperability, we recognize key business processes areas and enumerate high-level conceptual objects that need to be exchanged among supply chain or trading partners. Here, we also show example mappings of representative content standards onto the identified conceptual objects. We complete this chapter by providing an account of some advanced work to enhance

    Syndromic surveillance is an innovative surveillance tool used to support national surveillance programmes. Recent advances in the use of internet-based health data have demonstrated the potential usefulness of these health data; however, there have been limited studies comparing these innovative health data to existing established syndromic surveillance systems. We conducted a retrospective observational study to assess the usefulness of a national internet-based 'symptom checker' service for use as a syndromic surveillance system. NHS Direct online data were extracted for 1 August 2012 to 1 July 2013; a time-series analysis on the symptom categories self-reported by online users was undertaken and compared to existing telehealth syndromic data. There were 3·37 million online users of the internet-based self-checker compared to 1·43 million callers to the telephone triage health service. There was a good correlation between the online and telephone triage data for a number of syndromic indicators including cold/flu, difficulty breathing and eye problems; however, online data appeared to provide additional early warning over telephone triage health data. This assessment has illustrated some potential benefit of using internet-based symptom-checker data and provides the basis for further investigating how these data can be incorporated into national syndromic surveillance programmes.

  18. Operating Room Delays: Meaningful Use in Electronic Health Record.

    Perioperative areas are the most costly to operate and account for more than 40% of expenses. The high costs prompted one organization to analyze surgical delays through a retrospective review of their new electronic health record. Electronic health records have made it easier to access and aggregate clinical data; 2123 operating room cases were analyzed. Implementing a new electronic health record system is complex; inaccurate data and poor implementation can introduce new problems. Validating the electronic health record development processes determines the ease of use and the user interface, specifically related to user compliance with the intent of the electronic health record development. The revalidation process after implementation determines if the intent of the design was fulfilled and data can be meaningfully used. In this organization, the data fields completed through automation provided quantifiable, meaningful data. However, data fields completed by staff that required subjective decision making resulted in incomplete data nearly 24% of the time. The ease of use was further complicated by 490 permutations (combinations of delay types and reasons) that were built into the electronic health record. Operating room delay themes emerged notwithstanding the significant complexity of the electronic health record build; however, improved accuracy could improve meaningful data collection and a more accurate root cause analysis of operating room delays. Accurate and meaningful use of data affords a more reliable approach in quality, safety, and cost-effective initiatives. PMID:27046388

    For drug fostering and evolution, it is important to collect information directly from patients on the efficacy and safety of drugs as well as patient needs. At present, however, information gathered by healthcare professionals, pharmaceutical companies, or governments is not sufficient. There is concern that patients may fail to recognize the importance of providing information voluntarily. The present study was conducted to provide drug information to patients/consumers, to enlighten them on the importance of providing drug information by themselves, and to develop an Internet website, called "Minkusu," for collecting drug information from patients. This website is based on a registration system (free of charge). It is designed to provide information on proper drug use, and to collect opinions about drugs. As of May 31, 2012, a total of 1149 people had been registered. The male/female ratio of registered members was approximately 1:1, and patients/consumers accounted for 23%. According to the results of a questionnaire survey, several patient/consumer members appreciated the usefulness of the information service, and they took an opportunity to know of the concepts of drug development and evolution (Ikuyaku, in Japanese) through the information services provided by this site. In conclusion, the developed information system would contribute to the proper use of drugs by patients/consumers and to the promotion of drug development and evolution.

    1999-08-01

    After the Chernobyl accident caused the atmospheric release of radioactive substances that contaminated most of the European territory, the importance of supporting the decisional process in emergency conditions with reliable long-range dispersion models was understood. Generally, the reliability of models is evaluated and verified through comparison against measurements gained during planned experiments or accidental releases. The proper evaluation is based on a set of appropriate statistical indices, each of them giving insight into the specific characteristics of the model. This paper describes an Internet-based system (RTMOD, real time model evaluation) developed to compare in real time, on a graphical and numerical basis, the prediction of several long-range dispersion models. The structure of the system and some examples are presented in the following of this paper. RTMOD was developed to compare model predictions from various 'dry runs' (such as fictitious atmospheric releases), but it can also be used to compare model results against measurements in the situation of an actual release. Hence it is also a useful tool in validating mathematical dispersion models. Moreover, provided that a certain number of models are used, RTMOD becomes also a useful tool in real time managing of accidental releases by indicating the probability that a fixed threshold value will be exceeded, based on the set of model predictions.

    Occupation-based participatory assessment and treatment planning requires appropriate tools to explore clients' perceptions and priorities for their day-to-day lives. Currently, no such instrument is available in German for use with children and their proxies. This study aimed to translate and adapt the Perceived Efficacy and Goal Setting System (PEGS) for use in German-speaking regions. Translation, adaptation, and field testing of the Austrian-German PEGS version followed guidelines for cross-cultural adaptation of self-report assessments. Forty-two children, ages 5 to 10, with various health conditions, their parents, and teachers participated in this study. The Austrian-German PEGS was successfully translated and culturally adapted. Children, their parents, and teachers reported the child's competences related to the addressed items and identified goals for intervention. Participants added specific culturally relevant activities. Data can now be used to further develop the PEGS for German-speaking regions and to continue research on culturally meaningful activities for children and families. PMID:24695366

    Nurses at the bedside serve on "the front lines" as hospitals strive to prove their "meaningful use" of technology to the federal government in hopes of securing significant funds from the American Recovery and Reinvestment Act. Nurse informaticians, working in concert with chief nursing officers, guide the nursing organization toward the most effective and efficient ways to demonstrate "meaningful use." Armed with data points from the point of care, nurse informaticians and chief nursing officers will be able to quantify, for the very first time, the value of nursing's contribution to the quality of patient care in America.

    The objective of this research work is to simplify and improve the efficiency of cursor control and its interactions on the computer screen by applying fuzzy logic in its decision-making to make Internet users with disabilities use the networked computers conveniently and easily. "Point and click" interactions are one of the key features of operating systems based of graphical user interfaces (GUIs) [C.E. Steriadis, P. Constantinou, Designing human-computer interfaces for quadriplegic people, ACM Trans. Comput.-Hum.-Interact. (TOCHI) 10 (2) (2003) 87-118.]. People with severe motor-impairments due to spinal cord injury (SCI) or spinal cord dysfunction (SCD), however, often have difficulty with accurate and efficient control of pointing devices, limiting their integration to society and unassisted control over their environment through the use of such operating systems [S. Keates, F. Hwang, P. Langdon, P.J. Clarkson, P. Robinson, Cursor measures for motion-impaired computer users, in: Proceedings of ACM SIGCAPH Conference of Assistive Technologies - ASSETS 2002, pp. 135-142.]. The questions "How can someone with severe motor-impairments perform 'point and click' interactions as accurately and efficiently as an able-bodied person?" and "How can these interactions be advanced through use of Computational Intelligence (CI)?" are the driving forces behind the research described in this paper. Through this research, a novel fuzzy mouse cursor control system (FMCCS) is described. The FMCCS core consists of several fuzzy control functions, which define different user interactions with the system. Design and descriptions of these functions, as well first prototype implementation and testing with real users sustaining severe disabilities are presented.

    The present study involved the development of an Internet-based training system (ITS) to help train peer supervisors. The system, which was piloted with Dialectical Behavior Therapy (Linehan, 1993) using mock sessions, demonstrates how Internet-based technology can facilitate training protocols to support the ongoing training and supervision of therapists efficiently. Participant evaluation of the system was very positive, with over 90% of respondents reporting that they believed that the ITS was very useful or extremely useful for therapist training. Possible uses of the system include: (a) helping therapists to learn to discriminate more effective from less effective interventions to provide better feedback to supervisees and peers on their sessions, (b) helping therapists to improve their own ability to monitor and deliver a treatment effectively, and (c) helping to structure therapist training and supervision activities. The system could also be used to help with real-world supervision of therapists, assuming that legal and ethical issues associated with the use of the Internet for clinical supervision are addressed adequately.

    Cancer registration has developed in Europe over the last 50 years, and in the last decade intensive joint activities between the European Cancer Registries, in response to the need of pan-European harmonization of registration practices, have taken place. The Hungarian Paediatric Cancer Registry has been functioning as the database of the Hungarian Paediatric Oncology Network since 1971, aiming to follow the incidence and the treatment efficacy of malignant diseases. The goals of this globally unique open source information system are the following: 1) to raise the quality of the registration system to the European level by developing an Internet-based registration and communication system, modernizing the database, establishing automatic statistical analyses and adding an Internet website, 2) to support clinical epidemiological studies that we conduct with international collaborators on detailed analyses of the characteristics of patients and their diseases, evaluation of new diagnostic and therapeutic methods, prevention programs, and long-term quality of life and side effects. The benefits of the development of the Internet-based registration and communication system are as follows: a) introduction of an Internet-based case reporting system, b) modernization of the registry database according to international recommendations, c) automatic statistical summaries, encrypted mail systems, document repository, d) application of data security and privacy standards, e) establishment of a website and compilation of educational materials. The overall objective of this scientific project is to contribute towards the improvement of cancer prevention and cancer care for the benefit of the public in general and of cancer patients in particular.

    With the advent of broadcast television as a constant source of information throughout the NASA manned space flight Mission Control Center (MCC) at the Johnson Space Center (JSC), the current Video Transport System (VTS) characteristics provides the ability to visually enhance real-time applications as a broadcast channel that decision making flight controllers come to rely on, but can be difficult to maintain and costly. The Operations Technology Facility (OTF) of the Mission Operations Facility Division (MOFD) has been tasked to provide insight to new innovative technological solutions for the MCC environment focusing on alternative architectures for a VTS. New technology will be provided to enable sharing of all imagery from one specific computer display, better known as Display Sharing (DS), to other computer displays and display systems such as; large projector systems, flight control rooms, and back supporting rooms throughout the facilities and other offsite centers using IP networks. It has been stated that Internet Protocol (IP) applications are easily readied to substitute for the current visual architecture, but quality and speed may need to be forfeited for reducing cost and maintainability. Although the IP infrastructure can support many technologies, the simple task of sharing ones computer display can be rather clumsy and difficult to configure and manage to the many operators and products. The DS process shall invest in collectively automating the sharing of images while focusing on such characteristics as; managing bandwidth, encrypting security measures, synchronizing disconnections from loss of signal / loss of acquisitions, performance latency, and provide functions like, scalability, multi-sharing, ease of initial integration / sustained configuration, integration with video adjustments packages, collaborative tools, host / recipient controllability, and the utmost paramount priority, an enterprise solution that provides ownership to the whole

    Cheok, Adrian David

    Poultry are one of the most badly treated animals in the modern world. It has been shown that they have high levels of both cognition and feelings, and as a result there has been a recent trend of promoting poultry welfare. There is also a tradition of keeping poultry as pets in some parts of the world. However, in modern cities and societies, it is often difficult to maintain contact with pets, particularly for office workers. We propose and describe a novel cybernetics system to use mobile and Internet technology to improve human-pet interaction. It can also be used for people who are allergic to touching animals and thus cannot stroke them directly. This interaction encompasses both visualization and tactile sensation of real objects.

    Personnel from the Goddard Space Flight Center Wallops Flight Facility (GSFC/WFF) in Virginia are responsible for the overall management of the NASA Sounding Rocket Program. Payloads are generally in support of NASA's Space Science Enterprise's missions and return a variety of scientific data as well as providing a reasonably economical means of conducting engineering tests for instruments and devices used on satellites and other spacecraft. The fifteen types of sounding rockets used by NASA can carry payloads of various weights to altitudes from 50 km to more than 1,300 km. Launch activities are conducted not only from established missile ranges, but also from remote locations worldwide requiring mobile tracking and command equipment to be transported and set up at considerable expense. The advent of low earth orbit (LEO) commercial communications satellites provides an opportunity to dramatically reduce tracking and control costs of launch vehicles and Unpiloted Aerial Vehicles (UAVs) by reducing or eliminating this ground infrastructure. Additionally, since data transmission is by packetized Internet Protocol (IP), data can be received and commands initiated from practically any location. A low cost Commercial Off The Shelf (COTS) system is currently under development for sounding rockets which also has application to UAVs and scientific balloons. Due to relatively low data rate (9600 baud) currently available, the system will first be used to provide GPS data for tracking and vehicle recovery. Range safety requirements for launch vehicles usually stipulate at least two independent tracking sources. Most sounding rockets flown by NASA now carry GPS receivers that output position data via the payload telemetry system to the ground station. The Flight Modem can be configured as a completely separate link thereby eliminating requirement for tracking radar.

Payloads are generally in support of NASA's Space Science Enterprise's missions and return a variety of scientific data as well as providing a reasonably economical means of conducting engineering tests for instruments and devices used on satellites and other spacecraft. Sounding rockets used by NASA can carry payloads of various weights to altitudes from 50 km to more than 1,300 km. Scientific balloons can carry a payload weighing as much as 3,630 Kg to an altitude of 42 km. Launch activities for both are conducted not only from established ranges, but also from remote locations worldwide requiring mobile tracking and command equipment to be transported and set up at considerable expense. The advent of low earth orbit (LEO) commercial communications satellites provides an opportunity to dramatically reduce tracking and control costs of these launch vehicles and Unpiloted Aerial Vehicles (UAVs) by reducing or eliminating this ground infrastructure. Additionally, since data transmission is by packetized Internet Protocol (IP), data can be received and commands initiated from practically any location. A low cost Commercial Off The Shelf (COTS) system is currently under development for sounding rockets that also has application to UAVs and scientific balloons. Due to relatively low data rate (9600 baud) currently available, the system will first be used to provide GPS data for tracking and vehicle recovery. Range safety requirements for launch vehicles usually stipulate at least two independent tracking sources. Most sounding rockets flown by NASA now carry GP receivers that output position data via the payload telemetry system to the ground station. The Flight Modem can be configured as a completely separate link thereby eliminating the requirement for tracking radar. The

  1. Internet Policy

    NASA Astrophysics Data System (ADS)

    Lehr, William H.; Pupillo, Lorenzo Maria

    The Internet is now widely regarded as essential infrastructure for our global economy and society. It is in our homes and businesses. We use it to communicate and socialize, for research, and as a platform for E-commerce. In the late 1990s, much was predicted about what the Internet has become at present; but now, we have actual experience living with the Internet as a critical component of our everyday lives. Although the Internet has already had profound effects, there is much we have yet to realize. The present volume represents a third installment in a collaborative effort to highlight the all-encompassing, multidisciplinary implications of the Internet for public policy. The first installment was conceived in 1998, when we initiated plans to organize an international conference among academic, industry, and government officials to discuss the growing policy agenda posed by the Internet. The conference was hosted by the European Commission in Brussels in 1999 and brought together a diverse mix of perspectives on what the pressing policy issues would be confronting the Internet. All of the concerns identified remain with us today, including how to address the Digital Divide, how to modify intellectual property laws to accommodate the new realities of the Internet, what to do about Internet governance and name-space management, and how to evolve broadcast and telecommunications regulatory frameworks for a converged world.

    Internet addiction is defined as uncontrolled and harmful use of Internet, which manifests in three forms: gaming, various sexual activities and excessive use of emails, chats or SMS messaging. Several studies have found that abuse of alcohol and other substances, depression and other health problems are associated with Internet addiction. In boys and men depression may be more a consequence of the addiction than a cause for it. ADHD seems to be a significant background factor for developing the condition. Because it is almost impossible to lead a life without Internet and computers nowadays, it is unrealistic to aim towards full abstinence. Treatment has generally followed the guidelines adapted for pathological gambling.

    The Internet provides adults and children with a medium for professional and personal communication throughout the world. As widespread communication in cyberspace grows exponentially, the potential for Internet-related crimes, such as cyberstalkng, has accelerated. Children are particularly vulnerable to sexual predators, such as pedophiles, on the Internet. This article reports cases of pedophiles who used the information superhighway to exploit child victims. Two models of pedophilia on the Internet are discussed: a trust-based seductive model and a direct sexual model. This article explores the role that mental health professionals may play in the assessment of Internet pedophilia. For example, mental health professionals may provide psychiatric treatment to victims of Internet pedophiles. Psychiatrists may be involved in the evaluation of perpetrators of Internet crimes in a clinical or forensic setting. Governmental agencies, the criminal justice system, school, or the media may request consultations by mental health professionals as part of a multi-disciplinary approach to prevention. Methods of government intervention are discussed.

    In this article we discuss the effort made by the Internet Pilot to Physics (TIPTOP) project to develop a uniform and open information infrastructure for physics research and education. We discuss concepts such as communication in research and education, the importance of distributed indexing and catalogs, and briefly the use of new technology such as VRML and Java. We also stress the importance of developing and using standardized protocols and formats such as the Summary Object Interchangeable Format (SOIF) and Thematic Uniform Resource Agents (TURA). TIPTOP has rapidly grown to be one of the most popular physics Internet knowledge servers, and the recently established collaboration with the European Physical Society is an important step forward in developing a stable framework of high quality information for researchers and educators.

    The NASA Lewis Research Center is developing software tools to bridge the gap between the traditionally non-real-time Internet technology and the real-time, embedded-controls environment for space applications. Internet technology has been expanding at a phenomenal rate. The simple World Wide Web browsers (such as earlier versions of Netscape, Mosaic, and Internet Explorer) that resided on personal computers just a few years ago only enabled users to log into and view a remote computer site. With current browsers, users not only view but also interact with remote sites. In addition, the technology now supports numerous computer platforms (PC's, MAC's, and Unix platforms), thereby providing platform independence.In contrast, the development of software to interact with a microprocessor (embedded controller) that is used to monitor and control a space experiment has generally been a unique development effort. For each experiment, a specific graphical user interface (GUI) has been developed. This procedure works well for a single-user environment. However, the interface for the International Space Station (ISS) Fluids and Combustion Facility will have to enable scientists throughout the world and astronauts onboard the ISS, using different computer platforms, to interact with their experiments in the Fluids and Combustion Facility. Developing a specific GUI for all these users would be cost prohibitive. An innovative solution to this requirement, developed at Lewis, is to use Internet technology, where the general problem of platform independence has already been partially solved, and to leverage this expanding technology as new products are developed. This approach led to the development of the Embedded Web Technology (EWT) program at Lewis, which has the potential to significantly reduce software development costs for both flight and ground software.

  11. Dioxin surrogates - are there any meaningful ones?

    SciTech Connect

    Rigo, H.G.

    1997-12-01

    A number of easily measured pollutants have been offered up as dioxin surrogates - easily measured pollutants or process variables that consistently parallel dioxin emissions. Surrogates are a very attractive concept because the expense of direct dioxin measurement could be avoided. Also, the public can be assured that as long as easily and potentially continuously measured surrogates are within acceptable limits, people are not being exposed to excessive amounts of pollution. The question remains, however, is there a meaningful surrogate at conventionally regulated levels? Or, perhaps more importantly, at elevated levels that provide a comfortable margin of safety between normal operations and the conditions likely to represent elevated dioxin emissions?

  12. The impact of internet-connected control systems on the oil and gas industry

    NASA Astrophysics Data System (ADS)

    Martel, Ruth T.

    In industry and infrastructure today, communication is a way of life. In the oil and gas industry, the use of devices that communicate with the network at large is both commonplace and expected. Unfortunately, security on these devices is not always best. Many industrial control devices originate from legacy devices not originally configured with security in mind. All infrastructure and industry today has seen an increase in attacks on their networks and in some cases, a very dramatic increase, which should be a cause for alarm and action. The purpose of this research was to highlight the threat that Internet-connected devices present to an organization's network in the oil and gas industry and ultimately, to the business and possibly even human life. Although there are several previous studies that highlight the problem of these Internet-connected devices, there remains evidence that security response has not been adequate. The analysis conducted on only one easily discovered device serves as an example of the ongoing issue of the security mindset in the oil and gas industry. The ability to connect to a network through an Internet-connected device gives a hacker an anonymous backdoor to do great damage in that network. The hope is that the approach to security in infrastructure and especially the oil and gas industry, changes before a major catastrophe occurs involving human life.

    2014-01-01

    Background The use of Internet protocol television (IPTV) as a channel for consumer health information is a relatively under-explored area of medical Internet research. IPTV may afford new opportunities for health care service providers to provide health information and for consumers, patients, and caretakers to access health information. The technologies of Web 2.0 add a new and even less explored dimension to IPTV’s potential. Objective Our research explored an application of Web 2.0 integrated with IPTV for personalized home-based health information in diabetes education, particularly for people with diabetes who are not strong computer and Internet users, and thus may miss out on Web-based resources. We wanted to establish whether this system could enable diabetes educators to deliver personalized health information directly to people with diabetes in their homes; and whether this system could encourage people with diabetes who make little use of Web-based health information to build their health literacy via the interface of a home television screen and remote control. Methods This project was undertaken as design-based research in two stages. Stage 1 comprised a feasibility study into the technical work required to integrate an existing Web 2.0 platform with an existing IPTV system, populated with content and implemented for user trials in a laboratory setting. Stage 2 comprised an evaluation of the system by consumers and providers of diabetes information. Results The project succeeded in developing a Web 2.0 IPTV system for people with diabetes and low literacies and their diabetes educators. The performance of the system in the laboratory setting gave them the confidence to engage seriously in thinking about the actual and potential features and benefits of a more widely-implemented system. In their feedback they pointed out a range of critical usability and usefulness issues related to Web 2.0 affordances and learning fundamentals. They also described

    Dalley-Hewer, Jayne; Clouder, Deanne Lynn; Jackson, Ann; Goodman, Simon; Bluteau, Patricia; Davies, Bernadette

    2012-11-01

    This paper is concerned with identifying ways of facilitating "meaningful disagreement" amongst students in interprofessional online discussion forums. It builds on previous research that identified a trend toward polite agreement and only limited evidence of disagreement in this setting. Given the suggestion that disagreement indicates a deeper level of engagement in group discussion and therefore leads to deeper learning, our aim was to critique the pedagogical approach adopted by analyzing whether we were promoting a particular interprofessional discourse amongst students that favored agreement and therefore limited potential learning. Agreement in this context has been conceptualized as a form of online interprofessional "netiquette" existing amongst participants. Findings suggest that creating an online context for critical discourse is challenging; however, the careful construction of learning outcomes, trigger material/resources and learning activities, as well as attention to students' stage of study and life experience, can provoke the desired effects.

    2014-04-15

    Drinking water distribution infrastructure has been identified as a factor in waterborne disease outbreaks and improved understanding of the public health risks associated with distribution system failures has been identified as a priority area for research. Pipe breaks may pose a risk, as their occurrence and repair can result in low or negative pressure, potentially allowing contamination of drinking water from adjacent soils. However, measuring this phenomenon is challenging because the most likely health impact is mild gastrointestinal (GI) illness, which is unlikely to result in a doctor or hospital visit. Here we present a novel method that uses data mining techniques and internet search volume to assess the relationship between pipe breaks and symptoms of GI illness in two U.S. cities. Weekly search volume for the terms diarrhea and vomiting was used as the response variable with the number of pipe breaks in each city as a covariate as well as additional covariates to control for seasonal patterns, search volume persistence, and other sources of GI illness. The fit and predictive accuracy of multiple regression and data mining techniques were compared, with the best performance obtained using random forest and bagged regression tree models. Pipe breaks were found to be an important and positively correlated predictor of internet search volume in multiple models in both cities, supporting previous investigations that indicated an increased risk of GI illness from distribution system disturbances.

    The "Sky Glow Network" (SkyGlowNet) is an internet connected depository of photometric light at night (LAN) data that are collected automatically by static, internet-enabled Sky Brightness Meters (iSBMs). The data are collected nightly at high temporal frequency and can be used to monitor extended areas of sky brightness on hourly, nightly, monthly, seasonal, and annual cycles over long periods of time. The photometry can be used for scientific and community planning purposes, as well as a powerful tool for science, technology, engineering, and mathematics (STEM) educational outreach programs. The effective and efficient use of light in modern society has become an important and contentious issue that urgently requires better technical and societal understanding. It is important to us as astronomers, and will become increasingly relevant as dark sky areas shrink as a result of poorly implemented lighting. We outline the structure of SkyGlowNet, describe the iSBM unit, and discuss how to interact with the SkyGlowNet website. We discuss how these data can help us preserve observing sites in the future.

  20. Visual attentional capture predicts belief in a meaningful world.

    PubMed

    Bressan, Paola; Kramer, Peter; Germani, Mara

    2008-01-01

    Here we show that the automatic, involuntary process of attentional capture is predictive of beliefs that are typically considered as much more complex and higher-level. Whereas some beliefs are well supported by evidence, others, such as the belief that coincidences occur for a reason, are not. We argue that the tendency to assign meaning to coincidences is a byproduct of an adaptive system that creates and maintains cognitive schemata, and automatically directs attention to violations of a currently active schema. Earlier studies have shown that, within subjects, attentional capture increases with schema strength. Yet, between-subjects effects could exist too: whereas each of us has schemata of various strengths, most likely different individuals are differently inclined to maintain strong or weak ones. Since schemata can be interpreted as beliefs, we predict more attentional capture for subjects with stronger beliefs than for subjects with weaker ones. We measured visual attentional capture in a reaction time experiment, and correlated it with scores on questionnaires about religious and other beliefs and about meaningfulness and surprisingness of coincidences. We found that visual attentional capture predicts a belief in meaningfulness of coincidences, and that this belief mediates a relationship between visual attentional capture and religiosity. Remarkably, strong believers were more disturbed by schema violations than weak believers, and yet appeared less aware of the disrupting events. We conclude that (a) religious people have a stronger belief in meaningfulness of coincidences, indicative of a more general tendency to maintain strong schemata, and that (b) this belief leads them to suppress, ignore, or forget information that has demonstrably captured their attention, but happens to be inconsistent with their schemata.

    The aims of this study were to test the associations of the Internet addiction symptoms with impulsiveness, loneliness, novelty seeking and behavioral inhibition systems among adults with attention-deficit/hyperactivity disorder (ADHD) and adults with non-ADHD. A total of 146 adults aged between 19 and 33 years involved in this study. Participants were assessed with the Chinese version of the adult ADHD Self-report scale (ASRS), the Revised Chen Internet Addiction Scale (CIAS-R), the Barratt Impulsiveness Scale 11 (BIS-11), the Tridimensional Personality Questionnaire (TPQ), the UCLA loneliness scale, and the Behavioral Inhibition System and Behavioral Activation System Scale (BIS/BAS Scale). The results of hierarchical regression analysis indicated that impulsiveness, loneliness, and behavioral inhibition system were significant predictors of Internet addition among adults with ADHD. Higher loneliness was significantly associated with more severe Internet addition symptoms among the non-ADHD group. Adults with high impulsiveness, loneliness, and BIS should be treated with caution for preventing Internet addiction. In addition, adults with and without ADHD should be provided with different preventative strategies. PMID:27449004

    A randomized, controlled trial was conducted to assess the effectiveness of Blue Angel for Asthma Kids, an Internet-based interactive asthma educational and monitoring program, used in the management of asthmatic children. One hundred sixty-four (n = 164) pediatric patients with persistent asthma were enrolled and randomized into two study groups for a 12-week controlled trial. The intervention group had 88 participants who were taught to monitor their peak expiratory flows (PEF) and asthma symptoms daily on the Internet. They also received an interactive response consisting of a self-management plan from the Blue Angel monitoring program. The control group had 76 participants who received a traditional asthma care plan consisting of a written asthma diary supplemented with instructions for self-management. Disease control was assessed by weekly averaged PEF values, symptom scores, and asthma control tests. Adherence measures were assessed by therapeutic and diagnostic monitoring. Outcome was assessed by examining quality of life and retention of asthma knowledge. The data were analyzed by comparing results before and after the trial. At the end of trial, the intervention group decreased nighttime (-0.08 +/- 0.33 vs. 0.00 +/- 0.20, p = 0.028) and daytime symptoms (-0.08 +/- 0.33 vs. 0.01 +/- 0.18, p =0.009); improved morning (241.9 +/- 81.4 vs. 223.1 +/- 55.5, p =0.017) and night PEF (255.6 +/- 86.7 vs. 232.5 +/- 55.3, p =0.010); increased adherence rates (p < 0.05); improved well-controlled rates (70.4% vs. 55.3%, p < 0.05); improved knowledge regarding self-management (93.2% vs. 70.3%, p < 0.05); and improved quality of life (6.5 +/- 0.5 vs. 4.3 +/- 1.2 on a 7-point scale, p < 0.05) when compared with conventional management. The Internet-based asthma telemonitoring program increases selfmanagement skills, improves asthma outcomes, and appears to be an effective and well-accepted technology for the care of children with asthma and their caregivers.

    The so-called Internet of Things (IoT) has attracted increasing attention in the field of computer and information science. In this paper, a specific application of IoT, named Safety Management System for Tower Crane Groups (SMS-TC), is proposed for use in the construction industry field. The operating status of each tower crane was detected by a set of customized sensors, including horizontal and vertical position sensors for the trolley, angle sensors for the jib and load, tilt and wind speed sensors for the tower body. The sensor data is collected and processed by the Tower Crane Safety Terminal Equipment (TC-STE) installed in the driver's operating room. Wireless communication between each TC-STE and the Local Monitoring Terminal (LMT) at the ground worksite were fulfilled through a Zigbee wireless network. LMT can share the status information of the whole group with each TC-STE, while the LMT records the real-time data and reports it to the Remote Supervision Platform (RSP) through General Packet Radio Service (GPRS). Based on the global status data of the whole group, an anti-collision algorithm was executed in each TC-STE to ensure the safety of each tower crane during construction. Remote supervision can be fulfilled using our client software installed on a personal computer (PC) or smartphone. SMS-TC could be considered as a promising practical application that combines a Wireless Sensor Network with the Internet of Things.

    Many threats in the real world can be related to activity of persons on the internet. Internet surveillance aims to predict and prevent attacks and to assist in finding suspects based on information from the web. However, the amount of data on the internet rapidly increases and it is time consuming to monitor many websites. In this paper, we present a novel method to automatically monitor trends and find anomalies on the internet. The system was tested on Twitter data. The results showed that it can successfully recognize abnormal changes in activity or emotion.

In 2013, internet gaming disorder criteria have been proposed in the section of Conditions for Further Study of DSM-5. Existing epidemiological studies by questionnaire methods have reported that the prevalence of IA ranges between 2.8% and 9.9% among youths in Japan. Attention deficit hyperactivity disorder (ADHD), sleeping disorders, depression, obsessive compulsive disorder, and phobic anxiety disorder are extremely common comorbid mental disorders with IA. Some psychotherapies (e.g., cognitive behavioral therapy, motivational interviewing) and medical treatments (e.g., antidepressant drugs, methylphenidate) for comorbid mental disorders as well as rehabilitation (e.g., treatment camp) are effective for IA remission. However, some serious cases of IA may be difficult to treat, and prevention is very important. In future, the prevention, rehabilitations and treatments for IA will be more required in Japan.

    Background Graduate medical education faculty bear the responsibility of demonstrating active research and scholarship; however, faculty who choose education-focused careers may face unique obstacles related to the lack of promotion tracks, funding, career options, and research opportunities. Our objective was to address education research and scholarship barriers by providing a collaborative peer-mentoring environment and improve the production of research and scholarly outputs. Methods We describe a Medical Education Scholarship Support (MESS) group created in 2013. MESS is an interprofessional, multidisciplinary peer-mentoring education research community that now spans multiple institutions. This group meets monthly to address education research and scholarship challenges. Through this process, we develop new knowledge, research, and scholarly products, in addition to meaningful collaborations. Results MESS originated with eight founding members, all of whom still actively participate. MESS has proven to be a sustainable unfunded local community of practice, encouraging faculty to pursue health professions education (HPE) careers and fostering scholarship. We have met our original objectives that involved maintaining 100% participant retention; developing increased knowledge in at least seven content areas; and contributing to the development of 13 peer-reviewed publications, eight professional presentations, one Masters of Education project, and one educational curriculum. Discussion The number of individuals engaged in HPE research continues to rise. The MESS model could be adapted for use at other institutions, thereby reducing barriers HPE researchers face, providing an effective framework for trainees interested in education-focused careers, and having a broader impact on the education research landscape.

  13. Making biodiversity meaningful through environmental education

    2002-11-01

    Biodiversity is an emerging theme in science, society and, more recently, education. There is no one single definition of biodiversity that is adequate in all situations. Both the knowledge base and the value base of biodiversity are variable and questionable. Because of these characteristics, biodiversity makes for an interesting vehicle for linking science and society, and the investigation of the normative underpinnings of 'science-in-the making'. Based on a 3-year study, this paper explores the crossroads between science education and environmental education and presents a framework for tapping the environmental education potential of biodiversity. Outlined are a number stepping stones for making biodiversity meaningful to learners. It is argued that, from the perspective of environmental education, the illdefined nature of biodiversity is a useful feature. Biodiversity is renewing the discourse on nature conservation issues by bringing together different groups in society that are searching for a common language to discuss nature conservation issues in relation to sustainability issues. The resulting debate allows the socio-scientific dispute character of 'science-in-the-making' to surface. Participation in such a dispute is an excellent opportunity to learn about a highly relevant, controversial, emotionally charged and debatable topic at the crossroads of science, technology and society

  14. Postponement of death until symbolically meaningful occasions.

    This study shows that mortality dips before a symbolically meaningful occasion and peaks just afterward. Mortality among Chinese (n = 1288) dips by 35.1% in the week before the Harvest Moon Festival and peaks by the same amount (34.6%) in the week after. We chose to study mortality among Chinese and a Chinese holiday for two reasons. First, the holiday moves around the calendar, thus allowing separation of the effects of the holiday from fixed, monthly mortality effects. Second, the holiday appeals strongly to one (experimental) group and not to others (which can be used as control groups). In terms of percentage, cerebrovascular diseases displayed the largest dip/peak pattern, followed by diseases of the heart, and then malignant neoplasms. The dip/peak mortality pattern does not appear in various non-Chinese control groups. The statistical significance of the findings was demonstrated with linear and curvilinear regression analysis and with two nonparametric tests. After testing alternative explanations for the findings, we concluded that the dip/peak pattern occurs because death can be briefly postponed until after the occurrence of a significant occasion.

    1999-01-01

    This is the Final Report for the Internet Based Remote Operations Contract, has performed payload operations research support tasks March 1999 through September 1999. These tasks support the GSD goal of developing a secure, inexpensive data, voice, and video mission communications capability between remote payload investigators and the NASA payload operations team in the International Space Station (ISS) era. AZTek has provided feedback from the NASA payload community by utilizing its extensive payload development and operations experience to test and evaluate remote payload operations systems. AZTek has focused on use of the "public Internet" and inexpensive, Commercial-off-the-shelf (COTS) Internet-based tools that would most benefit "small" (e.g., $2 Million or less) payloads and small developers without permanent remote operations facilities. Such projects have limited budgets to support installation and development of high-speed dedicated communications links and high-end, custom ground support equipment and software. The primary conclusions of the study are as follows: (1) The trend of using Internet technology for "live" collaborative applications such as telescience will continue. The GSD-developed data and voice capabilities continued to work well over the "public" Internet during this period. 2. Transmitting multiple voice streams from a voice-conferencing server to a client PC to be mixed and played on the PC is feasible. 3. There are two classes of voice vendors in the market: - Large traditional phone equipment vendors pursuing integration of PSTN with Internet, and Small Internet startups.The key to selecting a vendor will be to find a company sufficiently large and established to provide a base voice-conferencing software product line for the next several years.

    The Operating Missions as Nodes on the Internet (OMNI) project has shown that Internet technology works in space missions through a demonstration using the UoSAT-12 spacecraft. An Internet Protocol (IP) stack was installed on the orbiting UoSAT-12 spacecraft and tests were run to demonstrate Internet connectivity and measure performance. This also forms the basis for demonstrating subsequent scenarios. This approach provides capabilities heretofore either too expensive or simply not feasible such as reconfiguration on orbit. The OMNI project recognized the need to reduce the risk perceived by mission managers and did this with a multi-phase strategy. In the initial phase, the concepts were implemented in a prototype system that includes space similar components communicating over the TDRS (space network) and the terrestrial Internet. The demonstration system includes a simulated spacecraft with sample instruments. Over 25 demonstrations have been given to mission and project managers, National Aeronautics and Space Administration (NASA), Department of Defense (DoD), contractor technologists and other decisions makers, This initial phase reached a high point with an OMNI demonstration given from a booth at the Johnson Space Center (JSC) Inspection Day 99 exhibition. The proof to mission managers is provided during this second phase with year 2000 accomplishments: testing the use of Internet technologies onboard an actual spacecraft. This was done with a series of tests performed using the UoSAT-12 spacecraft. This spacecraft was reconfigured on orbit at very low cost. The total period between concept and the first tests was only 6 months! On board software was modified to add an IP stack to support basic IP communications. Also added was support for ping, traceroute and network timing protocol (NTP) tests. These tests show that basic Internet functionality can be used onboard spacecraft. The performance of data was measured to show no degradation from current

    Purpose This study aimed to determine the temporal association of print media coverage and Internet search activity with adverse events reports associated with the human papillomavirus vaccine Gardasil® (HPV4) and the meningitis vaccine Menactra® (MNQ) among U.S. adolescents. Methods We used moderated linear regression to test the relationships between print media reports in top circulating newspapers, Internet search activity, and reports to the Vaccine Adverse Event Reporting System (VAERS) for HPV4 and MNQ during the first 2.5 years post-FDA approval. Results Compared to MNQ, HPV4 had more coverage in the print media and Internet search activity, which corresponded with the frequency of VAERS reports. In February 2007, we observed a spike in print media for HPV4. Although media coverage waned, Internet search activity remained stable and predicted the rise in HPV4-associated VAERS reports. Conclusions We demonstrate that media coverage and Internet search activity, in particular, may promote increased adverse event reporting. Public health officials who have long recognized the importance of proactive engagement with news media must now consider strategies for meaningful participation in Internet discussions.

    The number of resources available on the Internet continues to expand exponentially, but finding appropriate resources is still a fragmented, hit-or-miss operation. Traditional library expertise in bibliographic description and access should be applied to the management of this emerging body of material. In the process, catalogers will be able to assess the adequacy of current tools (e.g., cataloging codes, machine-readable cataloging formats, integrated library systems) for providing access to Internet resources and will contribute credibly to design or redesign of access tools. This paper outlines the major issues that must be considered in cataloging electronic resources. PMID:7599587

  20. Meaningful metrics for observatory publication statistics

    2012-09-01

    Observatories have wrestled for decades with the questions how to measure their importance to the astronomical community, what their scientific impact is, and how their performance in that respect compares to that of other observatories. There is a general sense that the answer is to be found in the publication record - specifically, in the refereed journal articles. However, simple parameters (such as the number of papers) are not helpful, because in isolation (applied to a single observatory) they are meaningless, while in comparison between observatories they are subject to external influences that all but invalidate the comparisons. We were fortunate in having the Chandra X-ray Observatory's bibliographic database with its rich variety of metadata available as a resource for experimenting with more sophisticated metrics. Out of this project we propose a modest set that contains meaningful information when viewed in the isolation of a single observatory as well as in comparison with other observatories. Even so, we urge users not to draw conclusions on the basis of the face value of the comparisons, but only after a serious analysis of potential causes for any differences or similarities. We have designed our metrics to provide useful information in three main areas of interest: speed of publication; fraction of observing time published; and archival usage. The basic measured parameters are the percentage of available observing time published as a function of the data's age, at a few specific age values; the median time it takes to publish observations; and similar parameters for multiple publications of the same observations. Citation of results is a fourth category, but it does not lend itself well to comparisons and defies the search for definite statements.

    The MS PHD'S Professional Development Program was established by and for UR/US populations to facilitate increased and sustained participation within the Earth system science community. MS PHD'S is jointly funded by NSF and NASA. Fourteen (14) minority Earth system scientists served as Program mentors and one- hundred fifteen (115) minority and non-minority scientists served as Meeting Mentors to student participants. Representatives from fifty-six (56) agencies and institutions provided support and exposure to MS PHD'S student participants. Two hundred fifty-eight (258) highly qualified UR/US students completed on-line applications to participate in the MS PHD'S Professional Development Program. Because of funding limitations, slightly fewer than 50% of the applicants were selected to participate. One-hundred twenty-six (126) undergraduate and graduate students from 26 states and Puerto Rico participated in the MS PHD'S program. Sixty-eight (68) MS PHD'S student participants self-identified as African American; thirty-four (34) as Puerto Rican; nine (9) as Hispanic/Mexican American, ten (10) as Native American and one (1) each as African, Asian, Pacific Islander, Hispanic and Multi-Ethnic. During the five year span of MS PHD'S programming, sixteen (16) student participants completed BS degrees, twelve (12) completed MS degrees and ten (10) completed the Doctoral degrees. How did MS PHD'S establish meaningful engagement to enhance diversity within the Earth system science community? This case study reveals replicable processes and constructs to enhance the quality of meaningful collaboration and engagement. In addition, the study addresses frequently asked questions (FAQ's) on outreach, recruitment, engagement, retention and success of students from underrepresented populations within diversity-focused programs.

    The Operating Missions as Nodes on the Internet (OMNI) project at NASA's Goddard Space flight Center (GSFC), is demonstrating the use of standard Internet protocols for spacecraft communication systems. This year, demonstrations of Internet access to a flying spacecraft have been performed with the UoSAT-12 spacecraft owned and operated by Surrey Satellite Technology Ltd. (SSTL). Previously, demonstrations were performed using a ground satellite simulator and NASA's Tracking and Data Relay Satellite System (TDRSS). These activities are part of NASA's Space Operations Management Office (SOMO) Technology Program, The work is focused on defining the communication architecture for future NASA missions to support both NASA's "faster, better, cheaper" concept and to enable new types of collaborative science. The use of standard Internet communication technology for spacecraft simplifies design, supports initial integration and test across an IP based network, and enables direct communication between scientists and instruments as well as between different spacecraft, The most recent demonstrations consisted of uploading an Internet Protocol (IP) software stack to the UoSAT- 12 spacecraft, simple modifications to the SSTL ground station, and a series of tests to measure performance of various Internet applications. The spacecraft was reconfigured on orbit at very low cost. The total period between concept and the first tests was only 3 months. The tests included basic network connectivity (PING), automated clock synchronization (NTP), and reliable file transfers (FTP). Future tests are planned to include additional protocols such as Mobile IP, e-mail, and virtual private networks (VPN) to enable automated, operational spacecraft communication networks. The work performed and results of the initial phase of tests are summarized in this paper. This work is funded and directed by NASA/GSFC with technical leadership by CSC in arrangement with SSTL, and Vytek Wireless.

The benefits include reduced mission costs and increased mission efficiency. The Internet-Based Space Command and Control System Architecture demonstrated at the NASA Inspection 2000 event proved that this communications architecture is viable for future NASA missions.

  9. Dynamics of Boolean networks controlled by biologically meaningful functions.

    PubMed

    Raeymaekers, L

    2002-10-01

    The remarkably stable dynamics displayed by randomly constructed Boolean networks is one of the most striking examples of the spontaneous emergence of self-organization in model systems composed of many interacting elements (Kauffman, S., J. theor. Biol.22, 437-467, 1969; The Origins of Order, Oxford University Press, Oxford, 1993). The dynamics of such networks is most stable for a connectivity of two inputs per element, and decreases dramatically with increasing number of connections. Whereas the simplicity of this model system allows the tracing of the dynamical trajectories, it leaves out many features of real biological connections. For instance, the dynamics has been studied in detail only for networks constructed by allowing all theoretically possible Boolean rules, whereas only a subset of them make sense in the material world. This paper analyses the effect on the dynamics of using only Boolean functions which are meaningful in a biological sense. This analysis is particularly relevant for nets with more than two inputs per element because biological networks generally appear to be more extensively interconnected. Sets of the meaningful functions were assembled for up to four inputs per element. The use of these rules results in a smaller number of distinct attractors which have a shorter length, with relatively little sensitivity to the size of the network and to the number of inputs per element. Forcing away the activator/inhibitor ratio from the expected value of 50% further enhances the stability. This effect is more pronounced for networks consisting of a majority of activators than for networks with a corresponding majority of inhibitors, indicating that the former allow the evolution of larger genetic networks. The data further support the idea of the usefulness of logical networks as a conceptual framework for the understanding of real-world phenomena.

    Background Recent prevalence data indicates that Pacific Islanders living in the United States have disproportionately high smoking rates when compared to the general populace. However, little is known about the factors contributing to tobacco use in this at-risk population. Moreover, few studies have attempted to determine these factors utilizing technology-based assessment techniques. Objective The objective was to develop a customized Internet-based Ecological Momentary Assessment (EMA) system capable of measuring cigarette use among Pacific Islanders in Southern California. This system integrated the ubiquity of text messaging, the ease of use associated with mobile phone apps, the enhanced functionality offered by Internet-based Cell phone-optimized Assessment Techniques (ICAT), and the high survey completion rates exhibited by EMA studies that used electronic diaries. These features were tested in a feasibility study designed to assess whether Pacific Islanders would respond to this method of measurement and whether the data gathered would lead to novel insights regarding the intrapersonal, social, and ecological factors associated with cigarette use. Methods 20 young adult smokers in Southern California who self-identified as Pacific Islanders were recruited by 5 community-based organizations to take part in a 7-day EMA study. Participants selected six consecutive two-hour time blocks per day during which they would be willing to receive a text message linking them to an online survey formatted for Web-enabled mobile phones. Both automated reminders and community coaches were used to facilitate survey completion. Results 720 surveys were completed from 840 survey time blocks, representing a completion rate of 86%. After adjusting for gender, age, and nicotine dependence, feeling happy (P=<.001) or wanting a cigarette while drinking alcohol (P=<.001) were positively associated with cigarette use.

    2014-10-01

    The vast numbers of military service members who have been deployed since 2001 highlights the need to better understand relationships of military couples. A unique consideration in military couples is the concept of meaningfulness of service, or the value service members and their partners place on military service in spite of the sacrifices it requires. In a sample of 606 Army couples, the authors used path analysis to examine how male service members' and female spouses' perceived meaningfulness of service added to the prediction of marital satisfaction in both members of the couple, when accounting for service members' PTSD symptoms. Spouses' perceived meaningfulness of service was linked with higher marital satisfaction in spouses, regardless of service member's perceived meaningfulness of service. Service members' perceived meaningfulness of service was also associated with increased marital satisfaction in service members, but only when their spouses also perceived higher meaningfulness. There were no significant interactions between service members' PTSD and either partner's perceived meaningfulness. Implications for enhanced attention to spousal perceptions of meaningfulness of service are discussed. PMID:25046347

    This study examined a model of meaningful work among a diverse sample of working adults. From the perspectives of Self-Determination Theory and the Psychology of Working Framework, we tested a structural model with social class and work volition predicting SDT motivation variables, which in turn predicted meaningful work. Partially supporting hypotheses, work volition was positively related to internal regulation and negatively related to amotivation, whereas social class was positively related to external regulation and amotivation. In turn, internal regulation was positively related to meaningful work, whereas external regulation and amotivation were negatively related to meaningful work. Indirect effects from work volition to meaningful work via internal regulation and amotivation were significant, and indirect effects from social class to meaningful work via external regulation and amotivation were significant. This study highlights the important relations between SDT motivation variables and meaningful work, especially the large positive relation between internal regulation and meaningful work. However, results also reveal that work volition and social class may play critical roles in predicting internal regulation, external regulation, and amotivation. PMID:26869970

    Recent advancements in the Internet of Things (IoT) and the Web of Things (WoT) accompany a smart life where real world objects, including sensing devices, are interconnected with each other. The Web representation of smart objects empowers innovative applications and services for various domains. To accelerate this approach, Web of Objects (WoO) focuses on the implementation aspects of bringing the assorted real world objects to the Web applications. In this paper; we propose an emergency fire management system in the WoO infrastructure. Consequently, we integrate the formation and management of Virtual Objects (ViO) which are derived from real world physical objects and are virtually connected with each other into the semantic ontology model. The charm of using the semantic ontology is that it allows information reusability, extensibility and interoperability, which enable ViOs to uphold orchestration, federation, collaboration and harmonization. Our system is context aware, as it receives contextual environmental information from distributed sensors and detects emergency situations. To handle a fire emergency, we present a decision support tool for the emergency fire management team. The previous fire incident log is the basis of the decision support system. A log repository collects all the emergency fire incident logs from ViOs and stores them in a repository.

    Recent advancements in the Internet of Things (IoT) and the Web of Things (WoT) accompany a smart life where real world objects, including sensing devices, are interconnected with each other. The Web representation of smart objects empowers innovative applications and services for various domains. To accelerate this approach, Web of Objects (WoO) focuses on the implementation aspects of bringing the assorted real world objects to the Web applications. In this paper; we propose an emergency fire management system in the WoO infrastructure. Consequently, we integrate the formation and management of Virtual Objects (ViO) which are derived from real world physical objects and are virtually connected with each other into the semantic ontology model. The charm of using the semantic ontology is that it allows information reusability, extensibility and interoperability, which enable ViOs to uphold orchestration, federation, collaboration and harmonization.

    The network requirements of control systems in industrial applications increase day by day. The Internet based control system and various fieldbus systems have been designed in order to meet these requirements. This paper describes an Internet based control system with wireless fieldbus communication designed for distributed processes. The system was implemented as an experimental setup in a laboratory. In industrial facilities, the process control layer and the distance connection of the distributed control devices in the lowest levels of the industrial production environment are provided with fieldbus networks. In this paper, the Internet based control system that will be able to meet the system requirements with a new-generation communication structure, which is called wired/wireless hybrid system, has been designed on field level and carried out to cover all sectors of distributed automation, from process control, to distributed input/output (I/O). The system has been accomplished by hardware structure with a programmable logic controller (PLC), a communication processor (CP) module, two industrial wireless modules and a distributed I/O module, Motor Protection Package (MPP) and software structure with WinCC flexible program used for the screen of Scada (Supervisory Control And Data Acquisition), SIMATIC MANAGER package program ("STEP7") used for the hardware and network configuration and also for downloading control program to PLC.

  5. Meaningful use of pharmacogenomics in health records: semantics should be made explicit.

    2010-01-01

    The recent emphasis on 'meaningful use' of electronic health records in health information technology reforms (e.g., as in the US stimulus package) can leverage the pharmacogenomics field. In order for clinical trials outcomes, based on pharmacogenomics research, to be meaningfully and effectively used in clinical practice there is a need to make health semantics explicit. Often, semantics is merely implicit in both the research and practice worlds and is buried in unstructured and disconnected descriptions of the data or just in the heads of human experts. Meaningful semantics includes rich metadata, but more importantly, the context of each discrete data item and how it relates to other data items in a specific dataset, as well as how it fits within the entire health record of an individual and how it references up-to-date clinical knowledge. Properly-built electronic health records systems based on standards could provide meaningful semantics on the healthcare side, while the fields of research and clinical trials need to come closer to healthcare in its data and knowledge representations in a way that lends itself to personalized medicine. The purpose of this review is to explore how evidence created by pharmacogenomics can be meaningfully delivered to healthcare through new approaches, such as electronic health records systems and information models.

    Three years ago Intermountain Healthcare made the decision to participate in the Medicare and Medicaid Electronic Heath Record (EHR) Incentive Program which required that hospitals and providers use a certified EHR in a meaningful way. At that time, the barriers to enhance our home grown system, and change clinician workflows were numerous and large. This paper describes the time and effort required to enhance our legacy systems in order to pass certification, including filling 47 gaps in (EHR) functionality. We also describe the processes and resources that resulted in successful changes to many clinical workflows required by clinicians to meet meaningful use requirements. In 2011 we set meaningful use targets of 75% of employed physicians and 75% of our hospitals to meet Stage 1 of meaningful use by 2013. By the end of 2013, 87% of 696 employed eligible professionals and 100% of 22 Intermountain hospitals had successfully attested for Stage 1. This paper describes documented and perceived costs to Intermountain including time, effort, resources, postponement of other projects, as well as documented and perceived benefits of attainment of meaningful use.

    The Internet has often been argued to have adverse psychological consequences, such as depression or anxiety symptoms, among "over-users." The present study offers an alternative understanding, suggesting the Internet may be used as a forum for expanding social networks and consequently enhancing the chance of meaningful relationships, self-confidence, social abilities, and social support. An online sample of 188 people was recruited over the Internet, while paper and pencil tests were administered to an offline sample group of 27 undergraduate university students, who were regular Internet users. Subjects completed the Zung Depression Scale (ZDS), Depression, Anxiety and Stress Scales (DASS), Eysenck Personality Questionnaire?Revised Short Scale (EPQ-R Short), Fear of Negative Evaluation (FNE) scale, Internet Use Questionnaire (IUQ), and an Internet Effects Questionnaire (IEQ). Results suggested that there was no relationship between time spent online and depression, anxiety, or social fearfulness. Those who primarily used the Internet for online chat believed that the Internet is psychologically beneficial to them, but also believed that frequent Internet users are lonely and that the Internet can be addictive. It is argued that "chat" users who are socially fearful may be using the Internet as a form of low-risk social approach and an opportunity to rehearse social behavior and communication skills, which, may help them improve interaction with offline, face-to-face, social environments.

    Descriptive naming systems allow clients to identify a set of objects by description. Described here is the construction of a descriptive naming system, called Univers, based on a model in which clients provide both an object description and some meta-information. The meta-information describes beliefs about the query and the naming system. Specifically, it is an ordering on a set of perfect world approximations, and it describes the preferred methods for accommodating imperfect information. The description is then resolved in a way that respects the preferred approximations.

    Lukose, Rajan Mathew

    The World Wide Web and the Internet are rapidly expanding spaces, of great economic and social significance, which offer an opportunity to study many phenomena, often previously inaccessible, on an unprecedented scale and resolution with relative ease. These phenomena are measurable on the scale of tens of millions of users and hundreds of millions of pages. By virtue of nearly complete electronic mediation, it is possible in principle to observe the time and ``spatial'' evolution of nearly all choices and interactions. This cyber-space therefore provides a view into a number of traditional research questions (from many academic disciplines) and creates its own new phenomena accessible for study. Despite its largely self-organized and dynamic nature, a number of robust quantitative regularities are found in the aggregate statistics of interesting and useful quantities. These regularities can be understood with the help of models that draw on ideas from statistical physics as well as other fields such as economics, psychology and decision theory. This thesis develops models that can account for regularities found in the statistics of Internet congestion and user surfing patterns and discusses some practical consequences. practical consequences.

  18. An interactive three-dimensional virtual body structures system for anatomical training over the internet.

    2006-04-01

    The Visible Human digital datasets make it possible to develop computer-based anatomical training systems that use virtual anatomical models (virtual body structures-VBS). Medical schools are combining these virtual training systems and classical anatomy teaching methods that use labeled images and cadaver dissection. In this paper we present a customizable web-based three-dimensional anatomy training system, W3D-VBS. W3D-VBS uses National Library of Medicine's (NLM) Visible Human Male datasets to interactively locate, explore, select, extract, highlight, label, and visualize, realistic 2D (using axial, coronal, and sagittal views) and 3D virtual structures. A real-time self-guided virtual tour of the entire body is designed to provide detailed anatomical information about structures, substructures, and proximal structures. The system thus facilitates learning of visuospatial relationships at a level of detail that may not be possible by any other means. The use of volumetric structures allows for repeated real-time virtual dissections, from any angle, at the convenience of the user. Volumetric (3D) virtual dissections are performed by adding, removing, highlighting, and labeling individual structures (and/or entire anatomical systems). The resultant virtual explorations (consisting of anatomical 2D/3D illustrations and animations), with user selected highlighting colors and label positions, can be saved and used for generating lesson plans and evaluation systems. Tracking users' progress using the evaluation system helps customize the curriculum, making W3D-VBS a powerful learning tool. Our plan is to incorporate other Visible Human segmented datasets, especially datasets with higher resolutions, that make it possible to include finer anatomical structures such as nerves and small vessels.

    Beside the optimization of biometric error rates the overall security system performance in respect to intentional security attacks plays an important role for biometric enabled authentication schemes. As traditionally most user authentication schemes are knowledge and/or possession based, firstly in this paper we present a methodology for a security analysis of Internet-based biometric authentication systems by enhancing known methodologies such as the CERT attack-taxonomy with a more detailed view on the OSI-Model. Secondly as proof of concept, the guidelines extracted from this methodology are strictly applied to an open source Internet-based biometric authentication system (BioWebAuth). As case studies, two exemplary attacks, based on the found security leaks, are investigated and the attack performance is presented to show that during the biometric authentication schemes beside biometric error performance tuning also security issues need to be addressed. Finally, some design recommendations are given in order to ensure a minimum security level.

    An increasing number of people search for health information online. During the last 10 years various researchers have determined the requirements for an ideal consumer health information system. The aim of this study was to figure out, whether medical laymen can find a more accurate diagnosis for a given anamnesis via the developed prototype health information system than via ordinary internet search.In a randomized controlled trial, the prototype information system was evaluated by the assessment of two sample cases. Participants had to determine the diagnosis of a patient with a headache via information found searching the web. A patient's history sheet and a computer with internet access were provided to the participants and they were guided through the study by an especially designed study website. The intervention group used the prototype information system; the control group used common search engines and portals. The numbers of correct diagnoses in each group were compared.A total of 140 (60/80) participants took part in two study sections. In the first case, which determined a common diagnosis, both groups did equally well. In the second section, which determined a less common and more complex case, the intervention group did significantly better (P=0.031) due to the tailored information supply.Using medical expert systems in combination with a portal searching meta-search engine represents a feasible strategy to provide reliable patient-tailored information and can ultimately contribute to patient safety with respect to information found via the internet.

    2013-11-01

    The sensor-to-controller and the controller-to-actuator delays in networked control systems (NCSs) are investigated for the first time with respect to their different effects on the system performance. This study starts with identifying the delay-independent and delay-dependent control laws in NCSs, and confirms that only two delay-dependent control laws can cause different delay effects in different channels. The conditions under which the different delays in different channels can cause different effects are then given for both delay-dependent control laws. The results are verified by numerical examples. Potentially, these results can be regarded as important design principles in the practical implementation of NCSs.

    2002-01-01

    Background The Internet and emergent telecommunications infrastructures are transforming the future of health care management. The costs of health care delivery systems, products, and services continue to rise everywhere, but performance of health care delivery is associated with institutional and ideological considerations as well as availability of financial and technological resources. Objective To identify the effects of ideological differences on health care market infrastructures including the Internet and telecommunications technologies by a comparative case analysis of two large health care organizations: the British National Health Service and the California-based Kaiser Permanente health maintenance organization. Methods A qualitative comparative analysis focusing on the British National Health Service and the Kaiser Permanente health maintenance organization to show how system infrastructures vary according to market dynamics dominated by health care institutions ("push") or by consumer demand ("pull"). System control mechanisms may be technologically embedded, institutional, or behavioral. Results The analysis suggests that telecommunications technologies and the Internet may contribute significantly to health care system performance in a context of ideological diversity. Conclusions The study offers evidence to validate alternative models of health care governance: the national constitution model, and the enterprise business contract model. This evidence also suggests important questions for health care policy makers as well as researchers in telecommunications, organizational theory, and health care management. PMID:12554552

    1998-04-01

    Lawrence Livermore National Laboratories` Zephyr System provides a showcase for the ways in which emerging technologies can help streamline procurement processes and improve the coordination between participants in engineering projects by allowing collaboration in ways that have not been possible before. The project also shows the success of a highly pragmatic approach that was initiated by the end user community, and that intentionally covered standard situations, rather than aiming at also automating the exceptions. By helping push purchasing responsibilities down to the end user, thereby greatly reducing the involvement of the purchasing department in operational activities, it was possible to streamline the process significantly resulting in time savings of up to 90%, major cost reductions, and improved quality. Left with less day-to- day purchasing operations, the purchasing department has more time for strategic tasks such as selecting and pre-qualifying new suppliers, negotiating blanket orders, or implementing new procurement systems. The case shows once more that the use of information technologies can result in major benefits when aligned with organizational adjustments.

    2007-01-01

    This study examines the impact of the Internet on the well-being of older Chinese. Thirty-three older Chinese, who were current or former students of a senior-oriented computer training organization based in Shanghai, China, were interviewed about their use and perceptions of the Internet. Data analysis was guided by grounded theory. The findings indicate that Internet learning and use in this peer group makes these older Chinese's lives after retirement more meaningful, and improves their self-evaluations as well as other people's views of them. These findings suggest that Internet learning and use is positively associated with the well-being of these older Chinese. This study also finds culturally specific factors-including mandatory retirement and recent economic reforms in China-that mediate older Chinese people's use and perceptions of the Internet. Finally, societal implications, limitations, and future research directions are discussed.

    Chandy, K.M.; Rifkin, A.; Sivilotti, P.A.G.

    1996-12-31

    This paper describes the design of a distributed system built using Java that supports peer-to-peer communication among processes spread across a network. We identify the requirements of a software layer that supports distributed computing, and we propose a design that meets those requirements. Our primary concerns are (1) the identification, specification, and implementation of software components that can be composed in different ways to develop correct distributed applications; (2) reasoning about the components systematically; and (3) providing services to the components. This paper deals with the last of these concerns. Though our implementation uses Java, the fundamental ideas apply to any object-oriented language that supports messaging and threads. Alternative implementations use such languages coupled with object request brokers or remote procedure invocation mechanisms.

    Vaginal microbicides potentially empower women to protect themselves from HIV and other sexually transmitted infections (STIs), especially when culture, religion, or social status may prevent them from negotiating condom use. The open literature contains minimal information on factors that drive user acceptability of women's health products or vaginal drug delivery systems. By understanding what women find to be most important with regard to sensory properties and product functionality, developers can iteratively formulate a more desirable product. Conjoint analysis is a technique widely used in market research to determine what combination of elements influence a consumer's willingness to try or use a product. We applied conjoint analysis here to better understand what sexually-active woman want in a microbicide, toward our goal of formulating a product that is highly acceptable to women. Both sensory and non-sensory attributes were tested, including shape, color, wait time, partner awareness, messiness/leakage, duration of protection, and functionality. Heterosexually active women between 18 and 35 years of age in the United States (n = 302) completed an anonymous online conjoint survey using IdeaMap software. Attributes (product elements) were systematically presented in various combinations; women rated these combinations of a 9-point willingness-to-try scale. By coupling systematic combinations and regression modeling, we can estimate the unique appeal of each element. In this population, a multifunctional product (i.e., broad spectrum STI protection, coupled with conception) is far more desirable than a microbicide targeted solely for HIV protection; we also found partner awareness and leakage are potentially strong barriers to use.

    The use of Internet references in academic literature is common, and Internet references are frequently inaccessible. The extent of Internet referencing and Internet reference activity in medical or scientific publications was systematically examined in more than 1000 articles published between 2000 and 2003 in the New England Journal of Medicine, The Journal of the American Medical Association, and Science. Internet references accounted for 2.6% of all references (672/25548) and in articles 27 months old, 13% of Internet references were inactive. Publishers, librarians, and readers need to reassess policies, archiving systems, and other resources for addressing Internet reference attrition to prevent further information loss.

  20. The meaningful encounter: patient and next-of-kin stories about their experience of meaningful encounters in health-care.

    This study focuses on the meaningful encounters of patients and next of kin, as seen from their perspective. Identifying the attributes within meaningful encounters is important for increased understanding of caring and to expand and develop earlier formulated knowledge about caring relationships. Caring theory about the caring relationship provided a point of departure to illuminate the meaningful encounter in healthcare contexts. A qualitative explorative design with a hermeneutic narrative approach was used to analyze and interpret written narratives. The phases of the analysis were naïve interpretation, structure analysis on two different levels (narrative structure, and deep structure through metaphors) and finally a dialectic interpretation. The narratives revealed the meaning of the meaningful encounter as sharing, a nourishing fellowship, common responsibility and coming together, experienced as safety and warmth, that gives, by extension, life-changing moments, a healing force and dissipated insight. The meaningful encounter can be seen as a complex phenomenon with various attributes. Understanding the meaningful encounter will enable nurses to plan and provide professional care, based on caring science, focusing on patient and next-of-kin experiences. PMID:23181930

    In today's healthcare system, there is an imbalance between what patients expect of caregivers' care and their perception of the care they get. How is it possible to reduce this imbalance? The aim of this paper was to describe attributes associated with meaningful encounters in the Swedish healthcare system based on patients' and caregivers' written narratives and to note the differences and similarities between the attributes identified by the two groups. This paper is a qualitative descriptive study. The analysis was guided by qualitative content analyses. Based on patients' narratives, attributes associated with a meaningful encounter fell into four categories: the kind-hearted caregiver, the thoughtful caregiver, the mutually oriented caregiver, and the helpful caregiver. Based on caregivers' narratives, the attributes were categorized as being humane, caring through physical contact, caring by nurturing communication, joy and laughter in care, and a sense of mutuality. The results show that there are both similarities and differences in patients' and caregivers' opinions about the attributes of a meaningful encounter. Knowing more about the attributes associated with meaningful encounters makes it possible for caregivers to individualize care for patients and makes it easier to help and support patients in what they most need support with.

    2016-09-01

    Recent neuroimaging work has identified a network of regions that work in concert to update impressions of other people, particularly in response to inconsistent behavior. However, the specific functional contributions of these regions to the updating process remain unclear. Using fMRI, we tested whether increases in activity triggered by inconsistent behavior reflect changes in the stored representations of other people in response to behavioral inconsistency, or merely a response to the inconsistency itself. Participants encountered a series of individuals whose behavior either changed in an attributionally meaningful fashion or was merely inconsistent with the immediately preceding behavior. We observed that left ventrolateral prefrontal cortex (vlPFC) and left inferior frontal gyrus (IFG) were preferentially recruited in response to unexpected, immoral behavior, whereas a separate set of regions (including dorsal anterior cingulate cortex, posterior cingulate cortex and temporoparietal junction/inferior parietal lobule) was preferentially recruited in response to more mundane inconsistencies in behavior. These results shed light on the distributed systems supporting impression updating. Specifically, while many regions supporting updating may primarily respond to moment-to-moment changes in behavior, a subset of regions (e.g. vlPFC and IFG) may contribute to updating person representations in response to trait-relevant changes in behavior.

    ABSTRACT Purpose: To describe the meaning of mentorship among Canadian orthopaedic physiotherapists. Methods: As part of a phenomenological qualitative study, 14 registered physiotherapists (13 women, 1 man) each participated in a single 60-minute, semi-structured face-to-face interview. Participants reflected on their experiences in receiving and providing mentorship and described the impact of mentorship on their careers. Interviews were transcribed verbatim and analyzed using a phenomenological approach. Results: Participants described mentorship as any nurturing process in which they used their skills and experience to guide, teach, and encourage a less skilled or less experienced colleague for the purpose of promoting professional and personal development. Participants experienced mentorship as a positive, reflective phenomenon. According to participants, the true essence of mentorship in physiotherapy consists of building passion, keeping fresh, making us stronger, and promoting deeper learning. Conclusions: Building a shared passion for learning, as well as a mentor's commitment to the mentee's success, forms the foundation of meaningful mentorship in physiotherapy. These mentoring relationships enable physiotherapists to adapt to the changing health care system, advance patient care, and develop the profession. PMID:23277688

    This article investigates the symbiotic relationship between drugs and the Internet, focusing (though not exclusively) on psychedelics. Programming on psychedelics in Silicon Valley from the 1960s to date is detailed, as are the twinned conceptualizations of drugs as a technology and technology as a drug. The correlation between drugs, the Internet, and consumerism is explored: the Internet is a medium through which "white," "grey" and "black" drug markets flourish. Thus, this article details the burgeoning online trades in pharmaceuticals, recreational, and "life-style" drugs that turn the Internet into a veritable candy store. Drug forums transmogrify into street corners, threatening the continued existence of the current system of global prohibition. However, it is arguably the use of the Web as an information source that may offer the greatest challenge to the incumbent paradigm, with experiential discourses offering alternatives to the hegemonic narrative, as the relationships between drugs, those who sell drugs and drug takers are reconfigured online.

    Meurant, Robert C.

    Second Language (L2) Digital Literacy is of emerging importance within English as a Foreign Language (EFL) in Korea, and will evolve to become regarded as the most critical component of overall L2 English Literacy. Computer-based Internet-hosted Learning Management Systems (LMS), such as the popular open-source Moodle, are rapidly being adopted worldwide for distance education, and are also being applied to blended (hybrid) education. In EFL Education, they have a special potential: by setting the LMS to force English to be used exclusively throughout a course website, the meta-language can be made the target L2 language. Of necessity, students develop the ability to use English to navigate the Internet, access and contribute to online resources, and engage in computer-mediated communication. Through such pragmatic engagement with English, students significantly develop their L2 Digital Literacy.

    The aim of the current project was to develop an Internet-based recruitment system for HIV and sexually transmitted infection (STI) screening for men who have sex with men (MSM) in Estonia in order to collect biological samples during behavioural studies. In 2013, an Internet-based HIV risk-behaviour survey was conducted among MSM living in Estonia. After completing the questionnaire, all participants were offered anonymous and free-of-charge STI testing. They could either order a urine sample kit by post to screen for chlamydia infections (including lymphogranuloma venereum (LGV)), trichomoniasis, gonorrhoea and Mycoplasma genitalium infections, or visit a laboratory for HIV, hepatitis A virus, hepatitis B virus,hepatitis C virus and syphilis screening. Of 301 participants who completed the questionnaire, 265 (88%),reported that they were MSM. Of these 265 MSM,68 (26%) underwent various types of testing. In the multiple regression analysis, Russian as the first language,previous HIV testing and living in a city or town increased the odds of testing during the study. Linking Internet-based behavioural data collection with biological sample collection is a promising approach. As there are no specific STI services for MSM in Estonia,this system could also be used as an additional option for anonymous and free-of-charge STI screening. PMID:25953131

    The rapid development and integration of the Internet into the mainstream of professional life provides the fuel cell industry with the opportunity to share new ideas with unprecedented capabilities. The U.S. Department of Energy's (DOE's) Morgantown Energy Technology Center (METC) has undertaken the task to maintain a Fuel Cell Forum on the Internet. Here, members can exchange ideas and information pertaining to fuel cell technologies. The purpose of this forum is to promote a better understanding of fuel cell concepts, terminology, processes, and issues relating to commercialization of fuel cell power technology. The Forum was developed by METC to provide those interested with fuel cell conference information for its current concept of exchanging ideas and information pertaining to fuel cells. Last August, the Forum expanded to an on-line and world-wide network. There are 250 members, and membership is growing at a rate of several new subscribers per week. The forum currently provides updated conference information and interactive information exchange. Forum membership is encouraged from utilities, industry, universities, and government. Because of the public nature of the internet, business sensitive, confidential, or proprietary information should not be placed on this system. The Forum is unmoderated; therefore, the views and opinions of authors expressed in the forum do not necessarily state or reflect those of the U.S. government or METC.

    Novice nurses’ inability to transfer classroom knowledge to the bedside has been implicated in adverse patient outcomes, including death. Concept-based teaching is a pedagogy found to improve knowledge transfer. Concept-based teaching emanates from a constructivist paradigm of teaching and learning and can be implemented most effectively when the underlying theory and principles are applied. Ausubel’s theory of meaningful learning and its construct of substantive knowledge integration provides a model to help educators to understand, implement, and evaluate concept-based teaching. Contemporary findings from the fields of cognitive psychology, human development, and neurobiology provide empirical evidence of the relationship between concept-based teaching, meaningful learning, and knowledge transfer. This article describes constructivist principles and meaningful learning as they apply to nursing pedagogy.

    OBJECTIVES To estimate meaningful improvements in gait speed observed during recovery from hip fracture and to evaluate the sensitivity and specificity of gait speed changes in detecting change in self-reported mobility. DESIGN Secondary longitudinal data analysis from two randomized controlled trials SETTING Twelve hospitals in the Baltimore, Maryland, area. PARTICIPANTS Two hundred seventeen women admitted with hip fracture. MEASUREMENTS Usual gait speed and self-reported mobility (ability to walk 1 block and climb 1 flight of stairs) measured 2 and 12 months after fracture. RESULTS Effect size–based estimates of meaningful differences were 0.03 for small differences and 0.09 for substantial differences. Depending on the anchor (stairs vs walking) and method (mean difference vs regression), anchor-based estimates ranged from 0.10 to 0.17 m/s for small meaningful improvements and 0.17 to 0.26 m/s for substantial meaningful improvement. Optimal gait speed cut-points yielded low sensitivity (0.39–0.62) and specificity (0.57–0.76) for improvements in self-reported mobility. CONCLUSION Results from this sample of women recovering from hip fracture provide only limited support for the 0.10-m/s cut point for substantial meaningful change previously identified in community-dwelling older adults experiencing declines in walking abilities. Anchor-based estimates and cut points derived from receiver operating characteristic curve analysis suggest that greater improvements in gait speed may be required for substantial perceived mobility improvement in female hip fracture patients. Furthermore, gait speed change performed poorly in discriminating change in self-reported mobility. Estimates of meaningful change in gait speed may differ based on the direction of change (improvement vs decline) or between patient populations. PMID:21883109

    Cloud computing is changing the ways software is developed and managed in enterprises, which is changing the way of doing business in that dynamically scalable and virtualized resources are regarded as services over the Internet. Traditional manufacturing systems such as supply chain management (SCM), customer relationship management (CRM), and enterprise resource planning (ERP) are often developed case by case. However, effective collaboration between different systems, platforms, programming languages, and interfaces has been suggested by researchers. In cloud-computing-based systems, distributed resources are encapsulated into cloud services and centrally managed, which allows high automation, flexibility, fast provision, and ease of integration at low cost. The integration between physical resources and cloud services can be improved by combining Internet of things (IoT) technology and Software-as-a-Service (SaaS) technology. This study proposes a new approach for developing cloud-based manufacturing systems based on a four-layer SaaS model. There are three main contributions of this paper: (1) enterprises can develop their own cloud-based logistic management information systems based on the approach proposed in this paper; (2) a case study based on literature reviews with experimental results is proposed to verify that the system performance is remarkable; (3) challenges encountered and feedback collected from T Company in the case study are discussed in this paper for the purpose of enterprise deployment.

Although the Internet is not necessarily making communication briefer (neither is the Internet making communication less formal), the Internet is manifesting our preference for writing over speaking. I propose that our preference for communicating through Internet-based text derives from a fundamental feature of writing: In contrast to speech, which is most often synchronous, text is most often asynchronous.

    PubMed

    2016-10-01

    Throughout our evolutionary history, our cognitive systems have been altered by the advent of technological inventions such as primitive tools, spoken language, writing, and arithmetic systems. Thirty years ago, the Internet surfaced as the latest technological invention poised to deeply reshape human cognition. With its multifaceted affordances, the Internet environment has profoundly transformed our thoughts and behaviors. Growing up with Internet technologies, "Digital Natives" gravitate toward "shallow" information processing behaviors characterized by rapid attention shifting and reduced deliberations. They engage in increased multitasking behaviors that are linked to increased distractibility and poor executive control abilities. Digital natives also exhibit higher prevalence of Internet-related addictive behaviors that reflect altered reward-processing and self-control mechanisms. Recent neuroimaging investigations have suggested associations between these Internet-related cognitive impacts and structural changes in the brain. Against mounting apprehension over the Internet's consequences on our cognitive systems, several researchers have lamented that these concerns were often exaggerated beyond existing scientific evidence. In the present review, we aim to provide an objective overview of the Internet's impacts on our cognitive systems. We critically discuss current empirical evidence about how the Internet environment has altered the cognitive behaviors and structures involved in information processing, executive control, and reward-processing.

  19. Relationships between students' meaningful learning orientation and their understanding of genetics topics

    NASA Astrophysics Data System (ADS)

    Cavallo, Ann M. Liberatore; Schafer, Larry E.

    This study explored factors predicting the extent to which high school students (N = 140) acquired meaningful understanding of the biological topics of meiosis, the Punnett-square method, and the relationships between these topics. This study (a) examined mental modeling as a technique for measuring students' meaningful understanding of the topics, (b) measured students' predisposed, generalized tendency to learn meaningfully (meaningful learning orientation), (c) determined the extent to which students' meaningful learning orientation predicted meaningful understanding beyond that predicted by aptitude and achievement motivation, (d) experimentally tested two instructional treatments (relationships presented to students, relationships generated by students), (e) explored the relationships of meaningful learning orientation, prior knowledge, instructional treatment, and all interactions of these variables in predicting meaningful understanding. The results of correlations and multiple regressions indicated that meaningful learning orientation contributed to students' attainment of meaningful understanding independent of aptitude and achievement motivation. Meaningful learning orientation and prior knowledge interacted in unique ways for each topic to predict students' attainment of meaningful understanding. Instructional treatment had relatively little relationship to students' acquisition of meaningful understanding, except for learners midrange between meaningful and rote. These findings imply that a meaningful learning approach among students may be important, perhaps as much or more than aptitude and achievement motivation, for their acquisition of interrelated, meaningful understandings of science.

  1. Meaningful Use Attestations among US Hospitals: The Growing Rural-Urban Divide.

    PubMed

    Sandefer, Ryan H; Marc, David T; Kleeberg, Paul

    2015-01-01

    The purpose of this study was to assess EHR Incentive Program attestations of eligible US hospitals across geography and hospital type. The proportions of attestations were compared between metropolitan, micropolitan, and rural hospitals and by whether a hospital was critical access or prospective payment system. From 2011 until December 2013, rural and critical access hospitals were attesting to meaningful use and receiving federal incentive payments at a significantly lower proportion than their urban counterparts. The data suggest that the digital divide between urban and rural hospitals that are adopting electronic health records and using the technology effectively is widening. These findings illustrate that the needs of rural hospitals currently and into the future are different than urban hospitals, and the meaningful use program does not appear to provide the resources needed to propel these rural hospitals forward.

Both research schools investigate social interactions as such, and conceptualize their organization in terms of autonomy. We ask what it could mean for an interaction to be autonomous, and discuss the structures and processes that contribute to and are maintained in the so-called interaction order. We also discuss the role played by individual vulnerability as well as the vulnerability of social interaction processes in the co-creation of meaningful action. Finally, we outline some implications of this interdisciplinary fraternization for the empirical study of social understanding, in particular in social neuroscience and psychology, pointing out the need for studies based on dynamic systems approaches on origins and references of coordination, and experimental designs to help understand human co-presence.

    2010-04-01

    The proposed federal "meaningful use" criteria for electronic health records include the direct engagement of patients in their care. In this study, we sought to describe the adoption and use of online services linked to the electronic health record at Group Health Cooperative. By August 2009, six years after the introduction of these services, 30 percent of outpatient "encounters" were actually conducted through secure electronic messaging. Meanwhile, 10 percent of enrollees reviewed medical test results online, while 10 percent went online to request medication refills. These results highlight the need to measure the patient experience as part of meaningful use and to enact policies supporting online and phone communication by patients and providers. PMID:20368589

  8. On Detectable and Meaningful Speech-Intelligibility Benefits.

    PubMed

    Whitmer, William M; McShefferty, David; Akeroyd, Michael A

    2016-01-01

    The most important parameter that affects the ability to hear and understand speech in the presence of background noise is the signal-to-noise ratio (SNR). Despite decades of research in speech intelligibility, it is not currently known how much improvement in SNR is needed to provide a meaningful benefit to someone. We propose that the underlying psychophysical basis to a meaningful benefit should be the just noticeable difference (JND) for SNR. The SNR JND was measured in a series of experiments using both adaptive and fixed-level procedures across participants of varying hearing ability. The results showed an average SNR JND of approximately 3 dB for sentences in same-spectrum noise. The role of the stimulus and link to intelligibility was examined by measuring speech-intelligibility psychometric functions and comparing the intelligibility JND estimated from those functions with measured SNR JNDs. Several experiments were then conducted to establish a just meaningful difference (JMD) for SNR. SNR changes that could induce intervention-seeking behaviour for an individual were measured with subjective scaling and report, using the same stimuli as the SNR JND experiment as pre- and post-benefit examples. The results across different rating and willingness-to-change tasks showed that the mean ratings increased near linearly with a change in SNR, but a change of at least 6 dB was necessary to reliably motivate participants to seek intervention. The magnitude of the JNDs and JMDs for speech-intelligibility benefits measured here suggest a gap between what is achievable and what is meaningful.

    PubMed

    2014-02-01

    Research in respiratory, sleep, and critical care medicine has historically been the domain of scientists and clinicians attempting to understand pathophysiological mechanisms and consequences of disease in an effort to develop effective treatments. This traditional approach of placing scientific rigor before the patient's reality is changing. There is growing recognition of the importance of integrating patient perspectives (e.g., preferences, expectations, and expanded definitions of what constitutes "successful" outcomes) into clinical research to achieve meaningful results for a broader group of stakeholders. This evolution is reflected in the growth of patient-centered organizations and patient advocacy groups that seek to meaningfully integrate patients into the process of prioritizing research needs and creating alliances wherein patients and researchers can partner together to accomplish research goals. In tandem, a growing number of real-world trials (i.e., those with broader, more representative patient populations and routine care pathways) now complement findings from traditional randomized controlled trials and offer new opportunities to design studies that better reflect patients' healthcare preferences and experiences. Patients' perspectives are key determinants of treatment adherence and outcomes, as well as the feasibility and likely value of implementing care pathways. The advent of smartphone and push technologies offer new opportunities for the collection of more patient-centered and ecologically valid patient data, thereby adding new dimensions to meaningfully integrate patients into real-world research.

  16. Evaluating housing quality, health and safety using an Internet-based data collection and response system: a cross-sectional study

    PubMed Central

    2010-01-01

    Background Typically housing and health surveys are not integrated together and therefore are not representative of population health or national housing stocks. In addition, the existing channels for distributing information about housing and health issues to the general public are limited. The aim of this study was to develop a data collection and response system that would allow us to assess the Finnish housing stock from the points of view of quality, health and safety, and also to provide a tool to distribute information about important housing health and safety issues. Methods The data collection and response system was tested with a sample of 3000 adults (one per household), who were randomly selected from the Finnish Population Register Centre. Spatial information about the exact location of the residences (i.e. coordinates) was included in the database inquiry. People could participate either by completing and returning a paper questionnaire or by completing the same questionnaire via the Internet. The respondents did not receive any compensation for their time in completing the questionnaire. Results This article describes the data collection and response system and presents the main results of the population-based testing of the system. A total of 1312 people (response rate 44%) answered the questionnaire, though only 80 answered via the Internet. A third of the respondents had indicated they wanted feedback. Albeit a majority (>90%) of the respondents reported being satisfied or quite satisfied with their residence, there were a number of prevalent housing issues identified that can be related to health and safety. Conclusions The collected database can be used to evaluate the quality of the housing stock in terms of occupant health and safety, and to model its association with occupant health and well-being. However, it must be noted that all the health outcomes gathered in this study are self-reported. A follow-up study is needed to evaluate whether

    What is the Internet? The Internet is the biggest network of information resources the world has ever seen and is growing rapidly each day. The Internet and the World Wide Web (The Web) represent the first technology to fully integrate the communications found on bookshelves, magazine racks, catalog files, fax machines, symposiums, in television/radio studios and the common mail system into a global infrastructure with extraordinary capabilities to deliver timely health care information. Unlike conventional media like newspapers or television, the Internet provides rapid one-to-one communication between millions of individuals. Television and newspapers communicate from "a few" (the writers and advertisers) to "many" (the readership). On the Internet, everyone is a "peer," being both an information provider and consumer on a 24-hour, 7-day a week basis. This article will discuss ways you can use the Internet's information resources in your own personal and professional life.

  18. Molecular and functional imaging of internet addiction.

    Zhu, Yunqi; Zhang, Hong; Tian, Mei

    2015-01-01

    Maladaptive use of the Internet results in Internet addiction (IA), which is associated with various negative consequences. Molecular and functional imaging techniques have been increasingly used for analysis of neurobiological changes and neurochemical correlates of IA. This review summarizes molecular and functional imaging findings on neurobiological mechanisms of IA, focusing on magnetic resonance imaging (MRI) and nuclear imaging modalities including positron emission tomography (PET) and single photon emission computed tomography (SPECT). MRI studies demonstrate that structural changes in frontal cortex are associated with functional abnormalities in Internet addicted subjects. Nuclear imaging findings indicate that IA is associated with dysfunction of the brain dopaminergic systems. Abnormal dopamine regulation of the prefrontal cortex (PFC) could underlie the enhanced motivational value and uncontrolled behavior over Internet overuse in addicted subjects. Further investigations are needed to determine specific changes in the Internet addictive brain, as well as their implications for behavior and cognition.

  1. History, structure, and function of the Internet.

    PubMed

    Glowniak, J

    1998-04-01

    The Internet stands at the forefront of telecommunications in medicine. This worldwide system of computers had its beginnings in networking projects in the United States and western Europe in the 1960s and 1970s. The precursor of the Internet was ARPANET, a long-distance telecommunication network funded by the Department of Defense that linked together computers throughout the United States. In the 1980s, ARPANET was superseded by NSFNET, a series of networks created by the National Science Foundation, which established the present-day structure of the Internet. The physical structure of the Internet resembles and is integrated with the telephone system. Long-distance data transport services are provided by large telecommunication companies, called network service providers (NSPs), through high-capacity, high-speed national and international fiber optic cables. These transport services are accessed through Internet service providers, ISPs. ISPs, the equivalent of regional Bell operating companies, provide the physical link to the NSPs for individuals and organizations. Telecommunications on the Internet are standardized by a set of communications protocols, the TCP/IP protocol suite, that describe routing of messages over the Internet, computer naming conventions, and commonly used Internet services such as e-mail. At present, the Internet consists of over 20 million computer worldwide and is continuing to grow at a rapid rate. Along with the growth of the Internet, higher speed access methods are offering a range of new services such as real-time video and voice communications. Medical education, teaching, and research, as well as clinical practice, will be affected in numerous different ways by these advances.

  2. On the costs and benefits of faces and words: process characteristics of feature search in highly meaningful stimuli.

    PubMed

    Wenger, Michael J; Townsend, James T

    2006-06-01

    The authors present a comprehensive consideration of the process characteristics of visual search in contexts that vary in their meaningfulness. The authors frame hypotheses regarding process architecture, stopping rule, capacity, and channel independence, using analytic results and a rigorously specified dynamic system to characterize a set of alternative hypotheses that vary along all of these dimensions. Results of the tests of these hypotheses suggest that process architecture and the stopping rule do not distinguish the processing of meaningful and meaningless forms. The major distinction between configural and nonconfigural processing was with regard to processing capacity, potentially implicating channel interdependencies. All of these conclusions hold for both faces and words.

    This commentary uses the lens of curricular implementation to consider issues and opportunities afforded by the papers in this special edition. While it is interesting to envision innovative approaches to physical education, actually implementing changes in the complex institutional school environment is exceptionally challenging. These authors have done an excellent job presenting viable solutions and fore grounding challenges. Yet, without a concerted effort to invite teachers to engage with us in this process, our implementation initiatives may not enhance the meaningful and educative process that these scholars envision for physical education.

  5. Measuring meaningful learning in the undergraduate chemistry laboratory

    NASA Astrophysics Data System (ADS)

    Galloway, Kelli R.

    The undergraduate chemistry laboratory has been an essential component in chemistry education for over a century. The literature includes reports on investigations of singular aspects laboratory learning and attempts to measure the efficacy of reformed laboratory curriculum as well as faculty goals for laboratory learning which found common goals among instructors for students to learn laboratory skills, techniques, experimental design, and to develop critical thinking skills. These findings are important for improving teaching and learning in the undergraduate chemistry laboratory, but research is needed to connect the faculty goals to student perceptions. This study was designed to explore students' ideas about learning in the undergraduate chemistry laboratory. Novak's Theory of Meaningful Learning was used as a guide for the data collection and analysis choices for this research. Novak's theory states that in order for meaningful learning to occur the cognitive, affective, and psychomotor domains must be integrated. The psychomotor domain is inherent in the chemistry laboratory, but the extent to which the cognitive and affective domains are integrated is unknown. For meaningful learning to occur in the laboratory, students must actively integrate both the cognitive domain and the affective domains into the "doing" of their laboratory work. The Meaningful Learning in the Laboratory Instrument (MLLI) was designed to measure students' cognitive and affective expectations and experiences within the context of conducting experiments in the undergraduate chemistry laboratory. Evidence for the validity and reliability of the data generated by the MLLI were collected from multiple quantitative studies: a one semester study at one university, a one semester study at 15 colleges and universities across the United States, and a longitudinal study where the MLLI was administered 6 times during two years of general and organic chemistry laboratory courses.

    2014-05-01

    Prince William County Public Schools and George Mason University in Virginia, USA, partnered to provide Meaningful Watershed Educational Experiences (MWEEs) for over 25,000 middle and high school students (11-18 year olds) across 34 schools. This school district, situated in a rapidly growing region 55 km southwest of Washington DC, has over 82,000 K-12 students. As native forest cover has been replaced with farming and urbanization, water quality has significantly degraded in the 166,534 km2 Chesapeake Bay watershed. This project was designed to increase student awareness of their impact on the land and waters of the largest estuary in the United States. MWEE is a long-term comprehensive project that incorporates a classroom preparation phase, a hands-on outdoor field investigation, and a reflection and data-sharing component. Training and technical assistance enhances the capacity of teachers of 6th grade, high school Earth Science and Environmental Science to deliver MWEEs which includes schoolyard stewardship, inquiry driven field study, use of hand-held technology and computer based mapping and analysis, project sharing and outreach. George Mason University researchers worked closely with K-12 science educators to create a comprehensive watershed-focused curriculum. Graduate and undergraduate students with strong interests in environmental science and education were trained to deliver the field investigation component of the MWEE. Representative teachers from each school were provided 3 days of professional development and were responsible for the training of their school's science education team. A comprehensive curriculum provided teachers with activities and tools designed to enhance students' mastery of state science objectives. Watershed concepts were used as the unifying theme to support student understanding of curriculum and STEM objectives including: scientific investigation, data collection and communication, chemistry, energy, erosion, human

    2013-01-01

    Much of what we know regarding the effect of stimulus repetition on neuroelectric adaptation comes from studies using artificially produced pure tones or harmonic complex sounds. Little is known about the neural processes associated with the representation of everyday sounds and how these may be affected by aging. In this study, we used real life, meaningful sounds presented at various azimuth positions and found that auditory evoked responses peaking at about 100 and 180 ms after sound onset decreased in amplitude with stimulus repetition. This neural adaptation was greater in young than in older adults and was more pronounced when the same sound was repeated at the same location. Moreover, the P2 waves showed differential patterns of domain-specific adaptation when location and identity was repeated among young adults. Background noise decreased ERP amplitudes and modulated the magnitude of repetition effects on both the N1 and P2 amplitude, and the effects were comparable in young and older adults. These findings reveal an age-related difference in the neural processes associated with adaptation to meaningful sounds, which may relate to older adults' difficulty in ignoring task-irrelevant stimuli.

    This paper presents some results of our recent research work related to the development of a new Collaborative Agent System Architecture (CASA) and an Infrastructure for Collaborative Agent Systems (ICAS). Initially being proposed as a general architecture for Internet based collaborative agent systems (particularly complex industrial collaborative agent systems), the proposed architecture is very suitable for managing the Internet enabled complex supply chain for a large manufacturing enterprise. The general collaborative agent system architecture with the basic communication and cooperation services, domain independent components, prototypes and mechanisms are described. Benefits of implementing Internet enabled supply chains with the proposed infrastructure are discussed. A case study on Internet enabled supply chain management is presented.

    In this study, we attempt to identify motives pivotal in choices made regarding online and offline game genres and assess whether they are meaningful predictors of Internet addiction. A separate goal was to determine how an assessment of Internet-related cognitions compares to criteria-based research instruments on Internet addiction, and demonstrate its clinical usefulness. We are using data from a cross-sectional study of the entire adolescent student population aged 12-18 of the island of Kos. Results indicate that specific game genres and motives for choosing a game are important predictors of Internet addiction, even after accounting for sociodemographic and Internet-use-related variables. Gender differences are not statistically important when we account for genre choices and motives for choosing them. Boys' thought content tends to revolve more around their Internet use compared to girls. Several patterns of motives to play specific genres were identified with the help of a canonical correlation analysis, demonstrating the fact that the simple observation of overt behavior is not enough to deduce the meaning of these actions for the individual. Using multiple measures of online addiction, examining genre preferences and underlying motives for choosing a game can be helpful in reaching a better understanding of the individual game player.

    The Internet is a very powerful and inexpensive tool that was created for the free distribution of knowledge and information. The Internet is a learning tool, a research tool, a virtual library without borders and membership requirements, a journal with instant publication, a help desk, and a newspaper/journal with current information. Very soon, when live audio and video transmission is perfected, the Internet also will be a live classroom and everyday conference. Forensic scientists, laboratories and colleges should make use of information already available on the Internet. They also should actively participate and contribute. Very few forensic scientists and laboratories have made their presence felt by setting up their home pages/web pages. But, there is tremendous growth during the past year. Immense benefits from Internet to forensic community are discussed along with the author's personal experience. Creating on-line searchable data bases in all specialties of forensic science is an urgent need. Leading forensic journals should take a lead and create on-line searchable indexes with abstracts. On line electronic publishing, collaborative research/paper publishing or editing is easy, fast, economical and convenient through the use of the Internet. Creation of Internet repositories of unpublished papers is an idea worth looking into. Internet also can be used to give training, re-training or advanced training to students/forensic scientists.

Unfortunately the percentage of people who use the internet excessively also increases. The concept of Internet addiction or pathological use of Internet is discussed in detail, and the characteristics of Internet addicts are also delineated. The social (especially the antisocial) use of Internet is discussed. It is argued that the behavior of Internet use is similar to daily life social behavior. In other words, Internet behavior is a kind of social behavior. Kohlberg's theory of moral development is employed to delineate the moral reasoning of the antisocial Internet behavior. The following behaviors are regarded as antisocial Internet behavior: (1) the use of Internet to carry out illegal activities such as selling faked products or offensive pornographic materials, (2) the use of Internet to bully others (i.e., cyberbullying) such as distributing libelous statements against a certain person, (3) the use of Internet to cheat others, and (4) the use of Internet to do illegal gambling.

    2002-01-01

    Internet is one of information technologies marking the transition from the second to the third millennium. The present role and expansion of Internet in medicine and healthcare is reviewed together with the perspective of further development. The beginning and initial expansion of the use of Internet in medicine are described. The World Wide Web (WWW or Web) is recognized as a major reason for this expansion, reaching a state described as a Web-pandemic. The rapid increase of the number of papers dealing with Internet in medical literature is presented as well as the appearance of several journals dedicated to Internet in medicine. First specialized symposia, among them MEDNET world conferences, are noted. First uses of Internet in medicine comprised databases, discussion groups, electronic newsletters, software archives and online public access catalogues. The appearance of the Web has led to a significant improvement of the Internet use in medicine, which is reflected in an exponential increase in the number of publications. It is noted that Internet allows "to do old things in new ways", but also "to do new things". It has become clear that the information revolution evoked by the internet shall leave a deep trace in medicine, as health information has become accessible to the public and ceased to be in exclusive control of health professionals. New medical fields--telemedicine and cybermedicine--appeared as the result of the development and global expansion of information and communication technologies, with cybermedicine dealing more specifically with the use of Internet. The advantages and disadvantages of cybermedicine are discussed, and major problems related to the quality of health information are highlighted. Several systems for quality criteria of health related Web-sites are described, indicating that Websites have to conform with the quality criteria such as transparency and honesty, accountability, privacy and data protection, currency

  9. A business case for HIT adoption: effects of "meaningful use" EHR financial incentives on clinic revenue.

    2010-01-01

    The goal of this study is to describe a framework that allows decision makers to efficiently evaluate factors that affect Electronic Health Record (EHR) adoption and test suitable interventions; specifically financial incentives. The United States healthcare delivery system is experiencing a transformation to improve population health. There is strong agreement that "meaningful use" of Health Information Technology (HIT) is a major enabler in this effort. However it's also understood that the high cost of implementing an EHR is an obstacle for adoption. To help understand these complexities we developed a simulation model designed to capture the dynamic nature of policy interventions that affect the adoption of EHR. We found that "Effective" use of HIT approaches break-even-point and larger clinic revenue many times faster that "average" or "poor" use of HIT. This study uses a systems perspective to the evaluate EHR adoption process through the "meaningful use" redesign as proposed in the American Reinvestment and Recovery Act 2009 in the United States healthcare industry by utilizing the System Dynamics methodology and Scenario Analysis.

    With nearly $30 billion in incentives available, it is critical to know to what extent US hospitals have been able to respond to those incentives by adopting electronic health record (EHR) systems that meet Medicare's criteria for their "meaningful use." Medicare has provided aggregate incentive payment data, but still missing is an understanding of how these payments are distributed across hospital types and years. Our analysis of Medicare data found a substantial increase in the percentage of hospitals receiving EHR incentive payments between 2011 (17.4 percent) and 2012 (36.8 percent). However, this increase was not uniform across all hospitals, and the overall proportion of hospitals receiving a payment for meaningful use was low. Critical-access, smaller, and publicly owned or nonprofit hospitals appeared to be at particular risk for failing to meet Medicare's meaningful-use criteria, and the overall proportion of hospitals receiving a payment for meaningful use was low. Starting in 2015, hospitals that fail to meet the criteria will be subject to financial penalties. To address the needs of institutions in danger of incurring these penalties, policy makers could implement targeted grant programs and provide additional information technology workforce support. In addition, the capacity of EHR system vendors should be carefully monitored to ensure that these institutions have access to the technology they need.

    In this highly technological age, health care providers are called to attend to the patient as a whole person, with dreams and goals and a desire for purpose and meaning in life. In this article, we propose a broadened definition of rehabilitation and a rehabilitation program designed to effect an improvement in the quality of life of each renal patient by aiming to restore meaningful existence in each of their lives. An individualized plan for rehabilitation can be constructed and implemented with far-reaching success when the focus is on the life goals of the patient, whether physical, social, psychological, or intellectual. These programs not only enhance the quality of life of the patient with end-stage renal disease, but are cost-effective, both at the societal level and at the level of the dialysis clinic.

    The professional standards of school nursing practice provide a framework to help school nurses focus on their unique mission of promoting health and academic achievement for all students. Without the standards, the nurse's role can become task oriented and limited in scope. By using an evaluation tool that reflects the standards, nurses not only become aware and begin to understand the standards; they also become directly accountable for meeting them. In addition, developing an evaluation process based on the standards of school nurse practice increases the visibility of school nurses and helps school administrators understand the role of the school nurse. This article describes how one school district integrated the scope and standards of school nursing into the job description and performance evaluation of the nurse. The process which is used to complete the evaluation in a manner that is meaningful and motivational to the school nurse is described. PMID:23263263

    Meaningful use legislation was first introduced in the American Recovery and Reinvestment Act of 2009 as a multistaged program to incentivize adoption of electronic health record technology. Since that time, numerous eligible providers and eligible hospitals have captured incentive payments by installing certified electronic health record technology and capturing and reporting on key elements for patients whose health records are stored in an electronic format. Although the question of whether radiologists should participate in the program was initially debated, the evidence is now clear that lack of participation leaves a significant amount of money at risk. This article provides an overview of how the program is structured, what technology needs to be installed, the necessary data elements to capture in an electronic format, and how radiologists can effectively participate in the program to capture their maximum incentive payment.

    Like most businesses, online pharmacy companies will only be successful if they make sure customers are satisfied with the service they receive. But what attributes of service quality lead to satisfaction and dissatisfaction? This study identified 19 Internet pharmacy service quality dimensions in three categories: (1) product cost and availability, (2) customer service, and (3) the online information system. Our analysis uncovered attributes that tend to determine consumer satisfaction and points out ways to improve overall service quality in the Internet pharmacy arena.

    The Heater of the Hypersonic Tunnel Facility (HTF) was modeled using SINDA/FLUINT thermal software. A description of the model is given. The project presented the opportunity of interfacing the thermal model with the Internet and was a demonstration that complex analysis is possible through the Internet. Some of the issues that need to be addressed related to interfacing software with the Internet are the following: justification for using the Internet, selection of the web server, choice of the CGI language, security of the system, communication among the parties, maintenance of state between web pages, and simultaneous users on the Internet system. The opportunities available for using the Internet for analysis are many and can present a significant jump in technology. This paper presents a vision how interfacing with the Internet could develop in the future. Using a separate Optical Internet (OI) for analysis, coupled with virtual reality analysis rooms (VRAR), could provide a synergistic environment to couple together engineering analysis within industry, academia, and government. The process of analysis could be broken down into sub-components so that specialization could occur resulting in superior quality, minimized cost and reduced time for engineering analysis and manufacturing. Some possible subcomponents of the system are solver routines, databases, Graphical User Interfaces, engineering design software, VRARs, computer processing, CAD systems, manufacturing, and a plethora of other options only limited by ones imagination. On a larger scope, the specialization of companies on the optical network would allow companies to rapidly construct and reconstruct their infrastructure based on changing economic conditions. This could transform business.

    The Health Information Technology for Economic and Clinical Health Act is intended to enhance reimbursement of health care providers for meaningful use of electronic health records systems. This presents both opportunities and challenges for public health departments. To earn incentive payments, clinical providers must exchange specified types of data with the public health system, such as immunization and syndromic surveillance data and notifiable disease reporting. However, a crisis looms because public health's information technology systems largely lack the capabilities to accept the types of data proposed for exchange. Cloud computing may be a solution for public health information systems. Through shared computing resources, public health departments could reap the benefits of electronic reporting within federal funding constraints. PMID:22390523

    Language's expressive power is largely attributable to its compositionality: meaningful words are combined into larger/higher-order structures with derived meaning. Despite its importance, little is known regarding the evolutionary origins and emergence of this syntactic ability. Although previous research has shown a rudimentary capability to combine meaningful calls in primates, because of a scarcity of comparative data, it is unclear to what extent analog forms might also exist outside of primates. Here, we address this ambiguity and provide evidence for rudimentary compositionality in the discrete vocal system of a social passerine, the pied babbler (Turdoides bicolor). Natural observations and predator presentations revealed that babblers produce acoustically distinct alert calls in response to close, low-urgency threats and recruitment calls when recruiting group members during locomotion. On encountering terrestrial predators, both vocalizations are combined into a "mobbing sequence," potentially to recruit group members in a dangerous situation. To investigate whether babblers process the sequence in a compositional way, we conducted systematic experiments, playing back the individual calls in isolation as well as naturally occurring and artificial sequences. Babblers reacted most strongly to mobbing sequence playbacks, showing a greater attentiveness and a quicker approach to the loudspeaker, compared with individual calls or control sequences. We conclude that the sequence constitutes a compositional structure, communicating information on both the context and the requested action. Our work supports previous research suggesting combinatoriality as a viable mechanism to increase communicative output and indicates that the ability to combine and process meaningful vocal structures, a basic syntax, may be more widespread than previously thought.

The evidence to date shows that these interventions are effective in reducing symptoms of depression. Metaanalyses report small-to-medium effect sizes when Internet interventions are delivered as stand-alone self-help interventions (d=0.25-0.36), and medium-to-large effect sizes when delivered as therapist-guided interventions (d=0.58-0.78), both compared with usual care. Only a minority of people suffering from depression receive adequate treatment, and Internet interventions might help bridge the large treatment gap. This review summarizes the current body of evidence and highlights pros and cons of Internet interventions. It also outlines how they could be implemented in mental health care systems and points out unresolved questions, as well as future directions, in this research field.

    Today's Internet provides a global data delivery service to millions of end users and routing protocols play a critical role in this service. It is important to be able to identify and diagnose any problems occurring in Internet routing. However, the Internet's sheer size makes this task difficult. One cannot easily extract out the most important or relevant routing information from the large amounts of data collected from multiple routers. To tackle this problem, we have developed Link-Rank, a tool to visualize Internet routing changes at the global scale. Link-Rank weighs links in a topological graph by the number of routes carried over each link and visually captures changes in link weights in the form of a topological graph with adjustable size. Using Link-Rank, network operators can easily observe important routing changes from massive amounts of routing data, discover otherwise unnoticed routing problems, understand the impact of topological events, and infer root causes of observed routing changes.

    The study objectives were to evaluate the correlates and psychosocial implications of internet gambling among adolescents, as well as the association between internet gambling and problematic internet use. A cross-sectional study design was applied among a random sample (N = 484) of adolescents (71.2% boys; 28.8% girls; mean age ± standard deviation, SD = 14.88 ± 0.55 years). Self-completed questionnaires, including internet gambling practices, internet use characteristics, Young Internet Addiction Test, and Strengths and Difficulties Questionnaire were utilized. The prevalence of internet gambling was 15.1%. Internet gambling was associated with psychosocial maladjustment, including Abnormal Conduct Problems (gender adjusted odds ratio, AOR = 3.83; 95% confidence interval, 95% CI: 1.86-7.92) and Borderline Peer Problems (AOR = 2.04; 95% CI: 1.09-3.85). The likelihood of concomitant problematic internet use was significantly higher among internet gamblers (AOR = 1.81; 95% CI: 1.03-3.19). Multivariate regression analyses indicated that among all characteristics of internet use assessed, utilizing the internet for the purposes of gambling practices was independently associated with problematic internet use among adolescents (AOR = 3.43; 95% CI: 1.40-8.39). Thus, the study findings suggest that adolescents who participate in internet gambling practices are more likely to concomitantly present with problematic internet use.

But it's the rotten ones that now tempt commercial, governmental, and consumer interests to threaten the Internet's uniquely creative power. The expediently selected, almost accidentally generative properties of the Internet - its technical openness, ease of access and mastery, and adaptability - have combined, especially when coupled with those of the PC, to produce an unsurpassed environment for innovative experiment. Those same properties, however, also make the Internet hospitable to various forms of wickedness: hacking, porn, spam, fraud, theft, predation, and attacks on the network itself. As these undesirable phenomena proliferate, business, government, and many users find common cause for locking down Internet and PC architecture in the interests of security and order. PC and Internet security vulnerabilities are a legitimate menace. However, the most likely reactions - if they are not forestalled - will be at least as unfortunate as the security problems themselves. Consider the growing profusion of "tethered appliances" - devices whose functions cannot readily be altered by their owners (think TiVo). Such appliances take Internet innovations and wrap them up in a neat, easy-to-use package, which is good - but only if the Internet and PC can remain sufficiently in the center of the digital ecosystem to produce the next round of innovations and to generate competition. People buy these devices for their convenience or functionality and may appreciate the fact that they are safer to use (they limit the damage users can do through ignorance or carelessness). But the risk is that users, by migrating to such appliances, will unwittingly trade away the future benefits of generativity - a loss that will go unappreciated even as innovation tapers off.

    Many of the pioneers of Internet business, both dot-coms and established companies, have competed in ways that violate nearly every precept of good strategy. Rather than focus on profits, they have chased customers indiscriminately through discounting, channel incentives, and advertising. Rather than concentrate on delivering value that earns an attractive price from customers, they have pursued indirect revenues such as advertising and click-through fees. Rather than make trade-offs, they have rushed to offer every conceivable product or service. It did not have to be this way--and it does not have to be in the future. When it comes to reinforcing a distinctive strategy, Michael Porter argues, the Internet provides a better technological platform than previous generations of IT. Gaining competitive advantage does not require a radically new approach to business; it requires building on the proven principles of effective strategy. Porter argues that, contrary to recent thought, the Internet is not disruptive to most existing industries and established companies. It rarely nullifies important sources of competitive advantage in an industry; it often makes them even more valuable. And as all companies embrace Internet technology, the Internet itself will be neutralized as a source of advantage. Robust competitive advantages will arise instead from traditional strengths such as unique products, proprietary content, and distinctive physical activities. Internet technology may be able to fortify those advantages, but it is unlikely to supplant them. Porter debunks such Internet myths as first-mover advantage, the power of virtual companies, and the multiplying rewards of network effects. He disentangles the distorted signals from the marketplace, explains why the Internet complements rather than cannibalizes existing ways of doing business, and outlines strategic imperatives for dot-coms and traditional companies.

  10. A clinically meaningful theory of outcome measures in rehabilitation medicine.

    PubMed

    Massof, Robert W

    2010-01-01

    Comparative effectiveness research in rehabilitation medicine requires the development and validation of clinically meaningful and scientifically rigorous measurements of patient states and theories that explain and predict outcomes of intervention. Patient traits are latent (unobservable) variables that can be measured only by inference from observations of surrogate manifest (observable) variables. In the behavioral sciences, latent variables are analogous to intensive physical variables such as temperature and manifest variables are analogous to extensive physical variables such as distance. Although only one variable at a time can be measured, the variable can have a multidimensional structure that must be understood in order to explain disagreements among different measures of the same variable. The use of Rasch theory to measure latent trait variables can be illustrated with a balance scale metaphor that has randomly added variability in the weights of the objects being measured. Knowledge of the distribution of the randomly added variability provides the theoretical structure for estimating measures from ordinal observation scores (e.g., performance measures or rating scales) using statistical inference. In rehabilitation medicine, the latent variable of primary interest is the patient's functional ability. Functional ability can be estimated from observations of surrogate performance measures (e.g., speed and accuracy) or self-report of the difficulty the patient experiences performing specific activities. A theoretical framework borrowed from project management, called the Activity Breakdown Structure (ABS), guides the choice of activities for assessment, based on the patient's value judgments, to make the observations clinically meaningful. In the case of low vision, the functional ability measure estimated from Rasch analysis of activity difficulty ratings was discovered to be a two-dimensional variable. The two visual function dimensions are independent

    2005-05-01

    Analysis of the heterogeneity of stream habitat and how biological communities respond to that complexity are fundamental components of ecosystem analysis that are often inadequately addressed in watershed assessments and restoration practices. Many aquatic species, such as the Foothill Yellow-legged Frog (Rana boylii), known to associate with certain physical habitats at various times throughout their lifecycle may require some degree of habitat complexity at a larger reach scale for a population to persist. Recent research in the field of landscape ecology has expanded the use of spatial heterogeneity indices to other fields of ecology as an objective method to quantify variability in habitat. Provided that indices are used in an appropriate context and are shown to be ecologically meaningful, they provide a potentially useful tool for quantifying the variability in riverine habitat for aquatic species such as R. boylii. This study evaluated whether stream reaches with a high heterogeneity of geomorphic features, as measured by several key spatial heterogeneity indices, correlated with a greater relative abundance of R. boylii. R. boylii habitat associations were quantified throughout a single season to obtain further insight into the local hydraulic and geomorphic conditions preferred by each lifestage. The two best predictors of habitat associations by lifestage were velocity and substrate size, two key characteristics of geomorphic units such as riffles and pools. The heterogeneity of geomorphic units was then quantified and measured at the reach scale using a variety of spatial indices. Indices of spatial composition, such as Shannon's Diversity Index, were found to correlate well with frog abundance, while indices of spatial configuration, such as Contagion, were not significant. These findings indicate R. boylii may select stream reaches with increased geomorphic complexity that potentially provide habitats suitable to each lifestage with multiple functions

    Mobile, wireless access and networking has emerged in the last few years as one of the most important directions of Internet growth. The popularity of mobile, and, more generally, nomadic Internet access is due to many enabling factors including: (a) emergence of meaningful applications tailored to the individual on the move; (b) small form factor and long battery life; (c) efficient middleware designed to support mobility; and, (d) efficient wireless networking technologies. A key player in the mobile Internet access is the nomad, i.e. the individual equipped with various computing and I/O gadgets (cellular phone, earphones, GPS navigator, palm pilot, beeper, portable scanner, digital camera, etc.). These devices form his/her Personal Area Network or PAN or personal bubble. The connectivity within the bubble is wireless (using for example a low cost, low power wireless LAN such as Bluetooth). The bubble can expand and contract dynamically depending on needs. It may temporarily include sensors and actuators as the nomad walks into a new environment. In this paper, we identify the need for the interconnection of the PAN with other wireless networks in order to achieve costeffective mobile access to the Internet. We will overview some key networking technologies required to support the PAN (eg, Bluetooth). We will also discuss an emerging technology, Ad Hoc wireless networking which is the natural complement of the PAN in sparsely populated areas. Finally, we will identify the need for intelligent routers to assist the mobile user in the selection of the best Internet access strategy.

    Eager to capitalize on the Internet's potential, many companies have allowed scores of on-line projects to bubble up throughout their organizations. The result? More harm than good, as companies find themselves confusing customers, aggravating employees, and wasting bushels of money. In this article, consultant Anthony Tjan explains how companies can do better. By adapting classical portfolio strategy to the digital age, executives can coordinate their Internet initiatives to avoid the needless headaches and spending, he says. Much of the market and industry data that underpin traditional portfolio analysis is unavailable for the Internet space, so Tjan replaces the two criteria used in traditional portfolio analysis--market position and industry attractiveness--with business viability and business fit. Viability captures the available quantitative data about an investment's likely payoff. Fit is qualitative; it measures the degree to which an investment dovetails with a company's existing processes, capabilities, and culture. Using viability and fit to assess their online initiatives, companies can then plot these efforts onto a simple matrix, called an Internet portfolio map. Their location on the matrix will suggest whether each initiative should be invested in, redesigned, sold or spun out, or killed. As Tjan notes, the process of organizing and evaluating new investment options against coherent, meaningful criteria isn't new. In the digital era, what is new are the tools you use. Internet portfolio planning is one such tool.

A simple calculation is presented showing the estimate of the throughput of the core photonic network branches. Optoelectronic components, circuits, systems and signals, together with analogous electronic entities and common software layers, are building blocks of the contemporary Internet. Participation of photonics in development of the physical layer in the future Internet will probably increase. The photonics leads now to a better usage of the available bandwidth (increase of the spectral efficiency measured in Bit/s/Hz), increase in the transmission rate (from Gbps, via Tbps up to probably Pbps), increase in the transmission distance without signal regeneration (in distortion compensated active optical cables), increase in energy/power efficiency measured in W/Gbps, etc. Photonics may lead, in the future, to fully transparent optical networks and, thus, to essential increase in bandwidth and network reliability. It is expected that photonics (with biochemistry, electronics and mechatronics) may build psychological and physiological interface for humans to the future global network. The following optical signal multiplexing methods were considered, which are possible without O/E/O conversion: TDM-OTDM, FDM-CO-OFDM, OCDM-OCDMA, WDM-DWDM.

    Each person expresses a potentially unique subset of ∼ 400 different olfactory receptor subtypes. Given that the receptors we express partially determine the odors we smell, it follows that each person may have a unique nose; to capture this, we devised a sensitive test of olfactory perception we termed the "olfactory fingerprint." Olfactory fingerprints relied on matrices of perceived odorant similarity derived from descriptors applied to the odorants. We initially fingerprinted 89 individuals using 28 odors and 54 descriptors. We found that each person had a unique olfactory fingerprint (P < 10(-10)), which was odor specific but descriptor independent. We could identify individuals from this pool using randomly selected sets of 7 odors and 11 descriptors alone. Extrapolating from this data, we determined that using 34 odors and 35 descriptors we could individually identify each of the 7 billion people on earth. Olfactory perception, however, fluctuates over time, calling into question our proposed perceptual readout of presumably stable genetic makeup. To test whether fingerprints remain informative despite this temporal fluctuation, building on the linkage between olfactory receptors and HLA, we hypothesized that olfactory perception may relate to HLA. We obtained olfactory fingerprints and HLA typing for 130 individuals, and found that olfactory fingerprint matching using only four odorants was significantly related to HLA matching (P < 10(-4)), such that olfactory fingerprints can save 32% of HLA tests in a population screen (P < 10(-6)). In conclusion, a precise measure of olfactory perception reveals meaningful nonolfactory genetic information.

    The present study extends the utility of the Pediatric Epilepsy Side Effects Questionnaire (PESQ) by determining distribution-based minimally clinically important difference (MCID) scores. Participants (N=682) were youth (ages 2-25) with newly diagnosed and chronic epilepsy pooled from research and clinical data in the Comprehensive Epilepsy Center. Caregivers completed the PESQ. Demographic and medical data were extracted from medical chart reviews or via a questionnaire. The MCIDs, which are the standard errors of measurement for each scale, for the entire sample were as follows: Cognitive=4.66, Motor=4.67, Behavior=8.05, General Neurological=7.41, Weight=9.58, and Total Side Effects=3.25. Additionally, MCIDs for patients with new-onset (<12months) epilepsy on monotherapy, new-onset epilepsy on polytherapy, chronic epilepsy on monotherapy (>12months), and chronic epilepsy on polytherapy were calculated. Results from the present study extend the utility of the PESQ by providing clinicians and researchers an enhanced understanding about clinically meaningful changes in side effect profiles across the pediatric epilepsy spectrum. These data can inform clinical decision-making for clinicians and researchers. PMID:25842203

    This paper presents our research on extracting meaningful climate indicator data from unsolicited observations ("tweets") made by Twitter users regarding their physical surroundings and events occurring around them. Our goal is to establish whether the existing understanding of climate indicator data collected by more traditional means could be usefully supplemented by information derived from the potentially rich but also statistically diffuse data resource represented by social media. To this end, we've initiated an ongoing effort to collect and analyze Twitter observations made on a wide variety of climate-related phenological, biological, epidemiological and meteorological phenomena. We report on our acquisition methodology and discuss in particular our rationale for selecting keywords, phrases and filters for our searches. The iterative process of assembling an inventory of hundreds of climate-related search terms has in and of itself yielded interesting and sometimes surprising insights on what is and isn't noticed and commented on via social media with respect to climate indicator phenomenology. We report some of the highlights of those analyses along with significant findings from the data acquisition to date. In conclusion, we discuss our preliminary assessment of the approach, how it can be generalized and extended for social media other than Twitter, and how the resulting data could be used to serve climate science objectives.

    The paper will provide an overview of the web-based distributed simulation software system developed for end-to-end, multi-spacecraft mission design, analysis, and test at the NASA Goddard Space Flight Center (GSFC). This software system was developed for an internal research and development (IR&D) activity at GSFC called the Distributed Space Systems (DSS) Distributed Synthesis Environment (DSE). The long-term goal of the DSS-DSE is to integrate existing GSFC stand-alone test beds, models, and simulation systems to create a "hands on", end-to-end simulation environment for mission design, trade studies and simulations. The short-term goal of the DSE was therefore to develop the system architecture, and then to prototype the core software simulation capability based on a distributed computing approach, with demonstrations of some key capabilities by the end of Fiscal Year 2002 (FY02). To achieve the DSS-DSE IR&D objective, the team adopted a reference model and mission upon which FY02 capabilities were developed. The software was prototyped according to the reference model, and demonstrations were conducted for the reference mission to validate interfaces, concepts, etc. The reference model, illustrated in Fig. 1, included both space and ground elements, with functional capabilities such as spacecraft dynamics and control, science data collection, space-to-space and space-to-ground communications, mission operations, science operations, and data processing, archival and distribution addressed.

    Intense craving is a core feature of addictive disorder, and cue-induced craving is believed to be a key factor in the maintenance and relapse of addictive behaviors. With the rapid development of the Internet, Internet addiction has become a widespread behavioral problem accompanied by many negative effects. This study used the cue-reactivity paradigm to examine cue-induced craving for the Internet among Internet addicts and non-addicts. Participants were exposed to Internet-related words, and asked to report their craving for the Internet. Results indicated that Internet-related words aroused cue-induced craving for the Internet among both Internet addicts and non-addicts; however, the craving was more intense among Internet addicts. These results suggest that craving may not be a unipolar, all or none state found only in addicts, but may also be present among non-addicts. They indicate that Internet-related words may be able to induce craving for the Internet, and that Internet addiction and other addictions may share similar underlying mechanisms. This finding has important implications for designing interventions for Internet addiction. PMID:27305097

    We describe our improved, robust, and scalable architecture by which to rapidly instrument large-scale watersheds, while providing the resulting data in real-time. Our system consists of more than twenty wireless sensor networks and thousands of sensors, which will be deployed in the American River basin (5000 sq. km) of California. The core component of our system is known as a mote, a tiny, ultra-low-power, embedded wireless computer that can be used for any number of sensing applications. Our new generation of motes is equipped with IPv6 functionality, effectively giving each sensor in the field its own unique IP address, thus permitting users to remotely interact with the devices without going through intermediary services. Thirty to fifty motes will be deployed across 1-2 square kilometer regions to form a mesh-based wireless sensor network. Redundancy of local wireless links will ensure that data will always be able to traverse the network, even if hash wintertime conditions adversely affect some network nodes. These networks will be used to develop spatial estimates of a number of hydrologic parameters, focusing especially on snowpack. Each wireless sensor network has one main network controller, which is responsible with interacting with an embedded Linux computer to relay information across higher-powered, long-range wireless links (cell modems, satellite, WiFi) to neighboring networks and remote, offsite servers. The network manager is also responsible for providing an Internet connection to each mote. Data collected by the sensors can either be read directly by remote hosts, or stored on centralized servers for future access. With 20 such networks deployed in the American River, our system will comprise an unprecedented cyber-physical architecture for measuring hydrologic parameters in large-scale basins. The spatiotemporal density and real-time nature of the data is also expected to significantly improve operational hydrology and water resource

    At this time, a fully materially closed system of large scale and complexity has not yet been built. However, Biosphere 2--a unique "living" Earth laboratory--is an example of a large (3.15 acres) and biologically complex (several thousand terrestrial plant species) system that can be operated with minimal exchange of ambient substances (annual exchange of materials is estimated to be approximately 10%). Biosphere 2 provides a multidisciplinary platform for scientific studies related to both Earth system processes and microcosms of the Earth that may be transported into space. The scale and versatility of the facility make Biosphere 2 a unique place to support integrated research and educational activities. The Biosphere 2 Global Change Testbed world wide web server has been developed to facilitate such activities by disseminating information about the facility, as well as current research and education efforts. Currently, these efforts focus of studies on carbon and other elemental cycles, coral reef ecology and physiology, stable isotopic research, studies in biodiversity, and ecophysiological studies of plant responses to elevated CO2. The Biosphere 2 Global Change Testbed web server is briefly described, and goals for use of the server to promote research and education endeavors are outlined.

  4. Global Considerations in Hierarchical Clustering Reveal Meaningful Patterns in Data

    2008-01-01

    Background A hierarchy, characterized by tree-like relationships, is a natural method of organizing data in various domains. When considering an unsupervised machine learning routine, such as clustering, a bottom-up hierarchical (BU, agglomerative) algorithm is used as a default and is often the only method applied. Methodology/Principal Findings We show that hierarchical clustering that involve global considerations, such as top-down (TD, divisive), or glocal (global-local) algorithms are better suited to reveal meaningful patterns in the data. This is demonstrated, by testing the correspondence between the results of several algorithms (TD, glocal and BU) and the correct annotations provided by experts. The correspondence was tested in multiple domains including gene expression experiments, stock trade records and functional protein families. The performance of each of the algorithms is evaluated by statistical criteria that are assigned to clusters (nodes of the hierarchy tree) based on expert-labeled data. Whereas TD algorithms perform better on global patterns, BU algorithms perform well and are advantageous when finer granularity of the data is sought. In addition, a novel TD algorithm that is based on genuine density of the data points is presented and is shown to outperform other divisive and agglomerative methods. Application of the algorithm to more than 500 protein sequences belonging to ion-channels illustrates the potential of the method for inferring overlooked functional annotations. ClustTree, a graphical Matlab toolbox for applying various hierarchical clustering algorithms and testing their quality is made available. Conclusions Although currently rarely used, global approaches, in particular, TD or glocal algorithms, should be considered in the exploratory process of clustering. In general, applying unsupervised clustering methods can leverage the quality of manually-created mapping of proteins families. As demonstrated, it can also provide

    We report the first results ever for real-time Internet performance to Africa using the PingER methodology. Multiple monitoring hosts were used to enable comparisons with performance from different parts of the world. From these preliminary measurements, we have found that Internet packet losses to some African sites in recent months range from very poor to bad (> 12%), some getting better, others are holding steady or getting worse. This, together with the average monthly Round Trip Times, imply end-to-end maximum TCP throughputs that are order of magnitudes different between countries in the region. Africa is shown to be far from the Internet performance in industrialized nations due to the poor infrastructure in place today. These monitoring efforts can provide valuable information to analyze the relative rates of future improvement and today they help us to quantify the digital divide and can provide quantitative information to policy makers.

    Librarianship is currently undergoing major changes. New information sources, accessible via the "network of networks", the Internet, offer opportunities which were previously unknown, but which require continuous ongoing learning. The Internet seems to be organized badly or not at all. The poor appearance might lead to an underestimation of its value. In the following, an introduction to the main functions will be given in order to facilitate understanding and use of the Internet. E-Mail, FTP (File Transfer Protocol) and Telnet will be covered, as well as Mailing lists, Newsgroups and the tools Archie, Gopher, Veronica, WAIS (Wide Area Information Server) and the World Wide Web (WWW). Examples will be given to show possible applications for library services.

    "Water is everywhere." This sentiment underscores the importance of instilling hydrologic and earth science literacy in educators, students, and the general public, but also presents challenges for water scientists and educators. Scientific data about water is collected and distributed by several different sources, from federal agencies to scientific investigators to citizen scientists. As competition for limited water resources increase, increasing access to and understanding of the wealth of information about the nation's and the world's water will be critical. The CUAHSI-HIS system is a web based system for sharing hydrologic data that can help address this need. HydroDesktop is a free, open source application for finding, getting, analyzing and using hydrologic data from the CUAHSI-HIS system. It works with HydroCatalog which indexes the data to find out what data exists and where it is, and then it retrieves the data from HydroServers where it is stored communicating using WaterOneFlow web services. Currently, there are over 65 services registered in HydroCatalog providing central discovery of water data from several federal and state agencies, university projects, and other sources. HydroDesktop provides a simplified GIS that allows users to incorporate spatial data, and simple analysis tools to facilitate graphing and visualization. HydroDesktop is designed to be useful for a number of different groups of users with a wide variety of needs and skill levels including university faculty, graduate and undergraduate students, K-12 students, engineering and scientific consultants, and others. This presentation will highlight some of the features of HydroDesktop and the CUAHSI-HIS system that make it particularly appropriate for use in educational and public outreach settings, and will present examples of educational use. The incorporation of "real data," localization to an area of interest, and problem-based learning are all recognized as effective strategies for

    The trend in most systems is that they are connected through the Internet. Traditional Supervisory Control and Data Acquisition Systems (SCADA) is connected only in a limited private network. SCADA is considered a critical infrastructure, and connecting to the internet is putting the society on jeopardy, some operators hold back on connecting it to the internet. But since the internet Supervisory Control and Data Acquisition Systems (SCADA) facility has brought a lot of advantages in terms of control, data viewing and generation. Along with these advantages, are security issues regarding web SCADA, operators are pushed to connect Supervisory Control and Data Acquisition Systems (SCADA) through the internet. Because of this, many issues regarding security surfaced. In this paper, we discuss web SCADA and the issues regarding security. As a countermeasure, a web SCADA security solution using crossed-crypto-scheme is proposed to be used in the communication of SCADA components.

    Collective knowledge as a social value may arise in cooperation among actors whose individual expertise is limited. The process of knowledge creation requires meaningful, logically coordinated interactions, which represents a challenging problem to physics and social dynamics modeling. By combining two-scale dynamics model with empirical data analysis from a well-known Questions &Answers system Mathematics, we show that this process occurs as a collective phenomenon in an enlarged network (of actors and their artifacts) where the cognitive recognition interactions are properly encoded. The emergent behavior is quantified by the information divergence and innovation advancing of knowledge over time and the signatures of self-organization and knowledge sharing communities. These measures elucidate the impact of each cognitive element and the individual actor's expertise in the collective dynamics. The results are relevant to stochastic processes involving smart components and to collaborative social endeavors, for instance, crowdsourcing scientific knowledge production with online games.

  16. Meaningful QQ adjustment of TRMM/GPM daily rainfall estimates.

    Pegram, Geoff; Bardossy, Andras; Sinclair, Scott

    2016-04-01

    In many parts of the world, particularly in Africa, the daily raingauge networks are sparse. It is therefore sensible to use remote sensing estimates of precipitation to fill the gaps, but readily available products like TRMM and it successor GPM are frequently found to be biased. This presentation describes a method of bias adjustment of TRMM using quantile-quantile (QQ) transforms of the probability distributions of TRMM daily rainfall accumulations over its grid of 0.25 degree pixels/blocks. There are 4 main steps in the procedure. The first is to collect the daily gauge readings in those TRMM pixels containing gauges to obtain useful estimates of spatial rainfall for ground referencing. These estimates need to be adjusted from gauge to areal estimates taking the number of gauges in each pixel into account. We found that the distributions of the areal rainfall estimates are influenced by the number of gauges in each block, so we devised a means of transforming point to areal rainfall meaningfully. The second step is to determine the parameters of the probability distributions of the gauge-based block areal rainfall; we found that the Weibull distribution with 2 parameters is a suitable and useful choice. The pairs of Weibull parameters of rainfall on many blocks are correlated. To enable their interpolation, as an intermediate step, they have to be decorrelated using canonical decomposition. These transformed parameter pairs are then separately interpolated to empty blocks over the region of choice. They are then back-transformed at each TRMM pixel to Weibull parameters to provide gauge referenced daily rainfall distributions. The third step is to determine the Weibull distributions of the TRMM daily rainfall estimates in each block, based on their brief 11-year history. The fourth and last step is to QQ transform the individual daily TRMM rainfall estimates via the interpolated gauge-block rainfall distributions. This procedure achieves the desired corrected

    Background Design and test the reliability of a web-based system for multicenter, real-time collection of data in the emergency department (ED), under waiver of authorization, in compliance with HIPAA. Methods This was a phase I, two-hospital study of patients undergoing evaluation for possible pulmonary embolism. Data were collected by on-duty clinicians on an HTML data collection form (prospective e-form), populated using either a personal digital assistant (PDA) or personal computer (PC). Data forms were uploaded to a central, offsite server using secure socket protocol transfer. Each form was assigned a unique identifier, and all PHI data were encrypted, but were password-accessible by authorized research personnel to complete a follow-up e-form. Results From April 15, 2003-April 15 2004, 1022 prospective e-forms and 605 follow-up e-forms were uploaded. Complexities of PDA use compelled clinicians to use PCs in the ED for data entry for most forms. No data were lost and server log query revealed no unauthorized entry. Prospectively obtained PHI data, encrypted upon server upload, were successfully decrypted using password-protected access to allow follow-up without difficulty in 605 cases. Non-PHI data from prospective and follow-up forms were available to the study investigators via standard file transfer protocol. Conclusions Data can be accurately collected from on-duty clinicians in the ED using real-time, PC-Internet data entry in compliance with the Privacy Rule. Deidentification-reidentification of PHI was successfully accomplished by a password-protected encryption-deencryption mechanism to permit follow-up by approved research personnel. PMID:15479471

  18. Streaming GNSS Data over the Internet

    NASA Astrophysics Data System (ADS)

    Gebhard, H.; Weber, G.; Dettmering, D.; Groeschel, M.

    2003-04-01

    Due to the increased capacity of the Internet, applications which transfer continuous data-streams by IP-packages, such as Internet Radio or Internet Video-on-Demand, have become well-established services. Growing mobile IP-Networks like GSM, GPRS, EDGE, or UMTS furthermore allow the mobile use of these real-time services. Compared to Multimedia applications, the bandwidth required for streaming GNSS data is relatively small. As a consequence, the global Internet can be used for the real-time collection and exchange of GNSS data, as well as for broadcasting derived differential products. Introducing the real time streaming of GNSS data via Internet as a professional service is demanding with respect to network transparency, network security, program stability, access control, remote administration, scalability and client simplicity. This paper will discuss several possible technical solutions: Unicast vs. IP-Multicast, TCP vs. UDP, Client/Server vs. Client/Server/Splitter technologies. Based on this discussion, a novel HTTP-based technique for streaming GNSS data to mobile clients over the Internet is introduced. It allows simultaneous access of a large number of PDAs, Laptops, or GNSS receivers to a broadcasting host via Mobile IP-Networks. The technique establishes a format called "Networked Transport of RTCM via Internet Protocol" (Ntrip), due to its main application being the dissemination of differential GNSS corrections in the popular RTCM-104 streaming format. Sufficient precision is obtained if data are not older than a few seconds. As the RTCM standard is used worldwide, most GNSS receivers accept it. This paper also focuses on system, implementation, and availability aspects of Ntrip-based differential GNSS services. The Ntrip components (NtripSources, NtripServers, NtripCaster, NtripClients) will be introduced, and software implementations will be described.

    The existing literatures highlights that the security is the primary factor which determines the adoption of Internet banking technology. The secondary information on Internet banking development in Malaysia shows a very slow growth rate. Hence, this study aims to study the banking customers perception towards security concern and Internet banking adoption through the information collected from 150 sample respondents. The data analysis reveals that the customers have much concern about security and privacy issue in adoption of Internet banking, whether the customers are adopted Internet banking or not. Hence, it infers that to popularize Internet banking system there is a need for improvement in security and privacy issue among the banking customers.

    More and more sensors are getting Internet connected. Examples are cameras on cell phones, CCTV cameras for traffic control as well as dedicated security and defense sensor systems. Due to the steadily increasing data volume, human exploitation of all this sensor data is impossible for effective mission execution. Smart access to all sensor data acts as enabler for questions such as "Is there a person behind this building" or "Alert me when a vehicle approaches". The GOOSE concept has the ambition to provide the capability to search semantically for any relevant information within "all" (including imaging) sensor streams in the entire Internet of sensors. This is similar to the capability provided by presently available Internet search engines which enable the retrieval of information on "all" web pages on the Internet. In line with current Internet search engines any indexing services shall be utilized cross-domain. The two main challenge for GOOSE is the Semantic Gap and Scalability. The GOOSE architecture consists of five elements: (1) an online extraction of primitives on each sensor stream; (2) an indexing and search mechanism for these primitives; (3) a ontology based semantic matching module; (4) a top-down hypothesis verification mechanism and (5) a controlling man-machine interface. This paper reports on the initial GOOSE demonstrator, which consists of the MES multimedia analysis platform and the CORTEX action recognition module. It also provides an outlook into future GOOSE development.

  11. Category-contingent face adaptation for novel colour categories: Contingent effects are seen only after social or meaningful labelling.

    PubMed

    Little, Anthony C; DeBruine, Lisa M; Jones, Benedict C

    2011-01-01

    A face appears normal when it approximates the average of a population. Consequently, exposure to faces biases perceptions of subsequently viewed faces such that faces similar to those recently seen are perceived as more normal. Simultaneously inducing such aftereffects in opposite directions for two groups of faces indicates somewhat discrete representations for those groups. Here we examine how labelling influences the perception of category in faces differing in colour. We show category-contingent aftereffects following exposure to faces differing in eye spacing (wide versus narrow) for blue versus red faces when such groups are consistently labelled with socially meaningful labels (Extravert versus Introvert; Soldier versus Builder). Category-contingent aftereffects were not seen using identical methodology when labels were not meaningful or were absent. These data suggest that human representations of faces can be rapidly tuned to code for meaningful social categories and that such tuning requires both a label and an associated visual difference. Results highlight the flexibility of the cognitive visual system to discriminate categories even in adulthood. PMID:21040911

    Meaningful use of electronic health records to coordinate care requires skillful synthesis and integration of subjective and objective data by practitioners to provide context for information. This is particularly relevant in the coordination of care for children with complex special health care needs. The purpose of this paper is to present a conceptual framework and example of meaningful use within an innovative telenursing intervention to coordinate care for children with complex special health care needs. The TeleFamilies intervention engages an advanced practice nurse in a full-time care coordinator role within an existing hospital-based medical home for children with complex special health care needs. Care coordination is facilitated by the synthesis and integration of internal and external data using an enhanced electronic health record and telehealth encounters via telephone and videoconferencing between the advanced practice nurse and the family at home. The advanced practice nurse’s ability to maintain an updated plan of care that is shared across providers and systems and build a relationship over time with the patient and family supports meaningful use of these data.

    How are scientists going to make use of the Internet several years from now? This is a case study of a leading-edge experiment in building a 'virtual institute'-- using electronic communication tools to foster collaboration among geographically dispersed scientists. Our experience suggests: Scientists will want to use web-based document management systems. There will be a demand for Internet-enabled meeting support tools. While internet videoconferencing will have limited value for scientists, webcams will be in great demand as a tool for transmitting pictures of objects and settings, rather than "talking heads." and a significant share of scientists who do fieldwork will embrace mobile voice, data and video communication tools. The setting for these findings is a research consortium called the NASA Astrobiology Institute.

  16. Cryptography and the Internet: lessons and challenges

    McCurley, K.S.

    1996-12-31

    The popularization of the Internet has brought fundamental changes to the world, because it allows a universal method of communication between computers. This carries enormous benefits with it, but also raises many security considerations. Cryptography is a fundamental technology used to provide security of computer networks, and there is currently a widespread engineering effort to incorporate cryptography into various aspects of the Internet. The system-level engineering required to provide security services for the Internet carries some important lessons for researchers whose study is focused on narrowly defined problems. It also offers challenges to the cryptographic research community by raising new questions not adequately addressed by the existing body of knowledge. This paper attempts to summarize some of these lessons and challenges for the cryptographic research community.

    1999-01-01

    The Internet holds promise of addressing some of dentists' and dental students' needs caused by the rapid expansion of knowledge. The Internet is used primarily for communication and for courses, but the quality of Internet courses is uneven. The Internet holds potential in formal dental education for supporting information and instructional databases and as an educational administrative tool. The use of the Internet for educational purposes raises issues such as locating resources on line, ensuring information quality, and incorporation of emerging computer architecture. Some projections are offered for the future: increased instructional quality, replacement of textbooks, creating "courses" out of modules of instructional material, faculty becoming coaches, increased use of trained instructional technologists, intelligent tutoring systems, and the merging of information, instruction, and practice systems. Numerous web sites are given.

    2014-07-01

    In our technology-savvy population, mental health professionals are seeing an increasing trend of excessive Internet use or Internet addiction. Researchers in China, Taiwan and Korea have done extensive research in the field of Internet addiction. Screening instruments are available to identify the presence of Internet addiction and its extent. Internet addiction is frequently associated with mental illnesses such as anxiety, depression, conduct disorder and attention deficit hyperactivity disorder (ADHD). Treatment modalities include individual and group therapies, cognitive behavioural therapy (CBT), family therapy and psychotropic medications. A significant proportion of Singapore adolescents engaging in excessive Internet use are also diagnosed to have concomitant Internet addiction. Despite the presence of a variety of treatment options, future research in this area is needed to address its growing trend and to minimise its negative psychological and social impact on the individuals and their families.

    2014-01-01

    Background Chemotherapy is an effective treatment in the fight against many cancers. Medication errors in oncology can be particularly serious given the narrow therapeutic window of antineoplastic drugs and their high toxicities. Computerized prescriber order entry (cpoe) has consistently been shown to reduce medication errors and adverse drug events in various settings, but its use in the oncology setting has not been well established. To gain a better understanding of the meaningful use of cpoe systems in the outpatient chemotherapy setting, we undertook a systematic review of systemic therapy cpoe. Methods A province-wide expert panel consisting of clinical experts, health information professionals, and specialists in human factors design provided guidance in the development of the research questions, search terms, databases, and inclusion criteria. The systematic review was undertaken by a core team consisting of a medical oncologist, nurse, pharmacist, and methodologist. The medline, embase, cinahl, and compendex databases were searched for relevant evidence. Results The database searches resulted in 5642 hits, of which 9 met the inclusion criteria and were retained. In the oncology setting, cpoe systems generally reduce chemotherapy medication errors; however, specific types of errors increase with the use of cpoe. These systems affect practice both positively and negatively with respect to time, workload, and productivity. Conclusions Despite the paucity of oncology-specific research, cpoe should be used in outpatient chemotherapy delivery to reduce chemotherapy-related medication errors. Adoption by clinicians will be enhanced by cpoe processes that complement current practice and workflow processes. PMID:25089110

    The Internet has revolutionized the way knowledge is currently produced, stored and disseminated. A few finger clicks on a keyboard can save time and many hours of search in libraries or shopping in stores. Online trademarks with an (e-) prefix such as e-library, e-business, e-health etc., are increasingly part of our daily professional vocabularies. However, the Internet has also produced multiple negative side effects, ranging from an unhealthy dependency to a dehumanization of human relationships. Fraudulent, unethical and scam practices are also flourishing through for example misleading online advertising methods. Some social and professional networks gather users' profiles for selling and advertising purposes, sometimes by making it technically difficult to unsubscribe. Here, I discuss some of these unethical aspects and propose some potential solutions to reduce them.

  17. [At the heart of Internet].

    Internet combines features of both a "coffee shop" and a "very large library". It is different from these two institutions in the innovating approach to information and its communication. The information is obtained by navigators, who recover documents dispersed in the four corners of the World Wide Web. The hypertext links between these documents explain the originality of the Web. They are a permanent invitation to look "somewhere else" to enrich the original site. Electronic messengers facilitate the exchange of information and documents. Room for discussion is available for all in the forums and to a well identified community in the lists of users. Internet is a decentralised and anarchic system. In order not to get lost, the sign posts must be followed. To avoid being a nuisance, there are rules of good conduct. You must not expect too much in order not to be disappointed: absolute security (with the risk of not having access) and perfect adequation of content (because of the risk of the loss of freedom of expression).

  18. Internet minimal group paradigm.

    Over many years, social psychologists have sought to understand what causes individuals to form themselves into groups. Initially, it was believed that groups were formed when people bonded around a common goal. Later, it was found that, when individuals were divided into groups on a random basis, this in itself was sufficient for them to feel part of a group and show a preference for their own group over others. Since the environment in cyberspace is different from that of the offline world, for example, there is no physical proximity between participants; it may be assumed that it would be difficult to achieve feelings of affiliation among potential or actual group members. This pioneer study seeks to discover which components are requisite to the creation of a group identity among individuals surfing the Internet. For this experiment, 24 people were divided into two Internet chat groups according to their intuitive preference in a decision-making task. It was found that group members perceived their own group performance as superior on a cognitive task as compared with that of the other group. These results demonstrate that for surfers, the Internet experience is very real and even a trivial allocation of people to a group is likely to create a situation of ingroup favoritism.

    Internet Cancer Support Groups (ICSGs) are an emerging form of support group on Internet specifically for cancer patients. Previous studies have indicated the effectiveness of ICSGs as a research setting or a data-collection method. Yet recent studies have also indicated that ICSGs tend to serve highly educated, high-income White males who tend to be at an early stage of cancer. In this article, a total of 317 general ICSGs and 229 ethnic-specific ICSGs searched through Google.com, Yahoo.com, http://Msn.com, AOL.com, and ACOR.org are analyzed from a feminist perspective. The written records of group discussions and written memos by the research staff members were also analyzed using content analysis. The idea categories that emerged about these groups include (a) authenticity issues; (b) ethnicity and gender issues; (c) intersubjectivity issues; and (d) potential ethical issues. The findings suggest that (a) researchers adopt multiple recruitment strategies through various Internet sites and/or real settings; (b) researchers raise their own awareness of the potential influences of the health-related resources provided by ICSGs and regularly update their knowledge related to the federal and state standards and/or policies related to ICSGs; and (c) researchers consider adopting a quota-sampling method.

  20. Modulation of Brain Activity during Action Observation: Influence of Perspective, Transitivity and Meaningfulness

    The coupling process between observed and performed actions is thought to be performed by a fronto-parietal perception-action system including regions of the inferior frontal gyrus and the inferior parietal lobule. When investigating the influence of the movements' characteristics on this process, most research on action observation has focused on only one particular variable even though the type of movements we observe can vary on several levels. By manipulating the visual perspective, transitivity and meaningfulness of observed movements in a functional magnetic resonance imaging study we aimed at investigating how the type of movements and the visual perspective can modulate brain activity during action observation in healthy individuals. Importantly, we used an active observation task where participants had to subsequently execute or imagine the observed movements. Our results show that the fronto-parietal regions of the perception action system were mostly recruited during the observation of meaningless actions while visual perspective had little influence on the activity within the perception-action system. Simultaneous investigation of several sources of modulation during active action observation is probably an approach that could lead to a greater ecological comprehension of this important sensorimotor process.

    To examine the prevalence of traditional and Internet bullying and the personal, family, and school environment characteristics of perpetrators and victims. Students (12-14 years old) in 35 junior high schools were randomly selected from the Jerusalem Hebrew (secular and religious) and Arab educational system (n = 2,610). Students answered an anonymous questionnaire, addressing personal, family, and school characteristics. Traditional bullying and Internet bullying for perpetrators and victims were categorized as either occurring at least sometimes during the school year or not occurring. Twenty-eight percent and 8.9 % of students were perpetrators of traditional and Internet bullying, respectively. The respective proportions of victims were 44.9 and 14.4 %. Traditional bullies presented higher Odds Ratios (ORs) for boys, for students with poor social skills (those who had difficulty in making friends, were influenced by peers in their behavior, or were bored), and for those who had poor communication with their parents. Boys and girls were equally likely to be Internet bullies and to use the Internet for communication and making friends. The OR for Internet bullying victims to be Internet bullying perpetrators was 3.70 (95 % confidence interval 2.47-5.55). Victims of traditional bullying felt helpless, and victims of traditional and Internet bullying find school to be a frightening place. There was a higher OR of Internet victimization with reports of loneliness. Traditional bully perpetrators present distinctive characteristics, while Internet perpetrators do not. Victims of traditional and Internet bullying feel fear in school. Tailored interventions are needed to address both types of bullying.

    Lack of occupation can lead to boredom, apathy, social exclusion and solitude. Occupation should incorporate meaningful activities. The aim of this study is to describe how Spanish Nursing Home residents experienced and made sense of meaningful activities. A qualitative phenomenological approach was followed. Data were collected over an 18-month period between 2012 and 2014. Purposeful sampling was conducted with Spanish residents in nursing homes in Madrid. Data were collected using unstructured and semi-structured interviews. The data were analyzed using the Giorgi proposal. Thirty-eight residents (20 female and 18 male) participated. Three main themes describing the significance of meaningful activity in nursing homes emerged from the data: Feeling the passage of time, Seeking an occupation, and Living with restrictions. Nursing homes should strive to develop diverse and meaningful activity programs for residents in order to occupy their time and provide them with a greater sense of purpose. PMID:26626463

    In this paper, a complete concept for Internet Electronic Data Interchange (EDI) - a well-known buzzword in the area of logistics and supply chain management to enable the automation of the interactions between companies and their partners - using XML (eXtensible Markup Language) will be proposed. This approach is based on Internet and XML, because the implementation of traditional EDI (e.g. EDIFACT, ANSI X.12) is mostly too costly for small and medium sized enterprises, which want to integrate their suppliers and customers in a supply chain. The paper will also present the results of the implementation of a prototype for such a system, which has been developed for an industrial partner to improve the current situation of parts delivery. The main functions of this system are an early warning system to detect problems during the parts delivery process as early as possible, and a transport following system to pursue the transportation.

  4. Risks and threats from internet access: Protecting the institution

    The Internet provides a number of capabilities to users. They can be divided into four general categories: (1) Email - to virtually anyone on an Internet node. (2) Telnet - a direct connection to remote computers on the Internet, providing access to files, indices and other information resources at those locations. (3) File Transfer Protocol (FTP) - a procedure which enables copying of files (documents, programs, pictures) between computing systems at different Internet locations. The ability to search for and retrieve files on the Internet may be accomplished with a variety of techniques having names like Gopher, Archie and Veronica. For our purposes, these fall into the FTP category. (4) News Groups - thousands of electronic discussion groups through which messages are disseminated to subscribing users at Internet locations. Each of these categories poses some threat to the institution providing Internet access to users. Those responsible for this resource must understand the threats and take appropriate action to protect both the resource and the institution. At Bentley College an Internet Policy (see Appendix A) is in place, which along with other policies and practices meets these challenges.

    Speech perception is critical to everyday life. Oftentimes noise can degrade a speech signal; however, because of the cues available to the listener, such as visual and semantic cues, noise rarely prevents conversations from continuing. The interaction of visual and semantic cues in aiding speech perception has been studied in young adults, but the extent to which these two cues interact for older adults has not been studied. To investigate the effect of visual and semantic cues on speech perception in older and younger adults, we recruited forty-five young adults (ages 18-35) and thirty-three older adults (ages 60-90) to participate in a speech perception task. Participants were presented with semantically meaningful and anomalous sentences in audio-only and audio-visual conditions. We hypothesized that young adults would outperform older adults across SNRs, modalities, and semantic contexts. In addition, we hypothesized that both young and older adults would receive a greater benefit from a semantically meaningful context in the audio-visual relative to audio-only modality. We predicted that young adults would receive greater visual benefit in semantically meaningful contexts relative to anomalous contexts. However, we predicted that older adults could receive a greater visual benefit in either semantically meaningful or anomalous contexts. Results suggested that in the most supportive context, that is, semantically meaningful sentences presented in the audiovisual modality, older adults performed similarly to young adults. In addition, both groups received the same amount of visual and meaningful benefit. Lastly, across groups, a semantically meaningful context provided more benefit in the audio-visual modality relative to the audio-only modality, and the presence of visual cues provided more benefit in semantically meaningful contexts relative to anomalous contexts.

    2012-04-01

    Internet of Things is a term that refers to "uniquely identifiable objects (things) and their virtual representations in an Internet-like structure" (Wikipedia). We here use the term to describe new and innovative ways to integrate physical samples in the Earth Sciences into the emerging digital infrastructures that are developed to support research and education in the Geosciences. Many Earth Science data are acquired on solid earth samples through observations and experiments conducted in the field or in the lab. The application and long-term utility of sample-based data for science is critically dependent on (a) the availability of information (metadata) about the samples such as geographical location where the sample was collected, time of sampling, sampling method, etc. (b) links between the different data types available for individual samples that are dispersed in the literature and in digital data repositories, and (c) access to the samples themselves. Neither of these requirements could be achieved in the past due to incomplete documentation of samples in publications, use of ambiguous sample names, and the lack of a central catalog that allows researchers to find a sample's archiving location. New internet-based capabilities have been developed over the past few years for the registration and unique identification of samples that make it possible to overcome these problems. Services for the registration and unique identification of samples are provided by the System for Earth Sample Registration SESAR (www.geosamples.org). SESAR developed the International Geo Sample Number, or IGSN, as a unique identifier for samples and specimens collected from our natural environment. Since December 2011, the IGSN is governed by an international organization, the IGSN eV (www.igsn.org), which endorses and promotes an internationally unified approach for registration and discovery of physical specimens in the Geoscience community and is establishing a new modular and

    The Meaningful Activity Participation Assessment (MAPA), a recently developed 28-item tool designed to measure the meaningfulness of activity, was tested in a sample of 154 older adults. The MAPA evidenced a sufficient level of internal consistency and test-retest reliability and correlated as theoretically predicted with the Life Satisfaction Index-Z, the Satisfaction with Life Scale, the Engagement in Meaningful Activities Survey, the Purpose in Life Test, the Center for Epidemiologic Studies Depression Inventory and the Rand SF-36v2 Health Survey subscales. Zero-order correlations consistently demonstrated meaningful relationships between the MAPA and scales of psychosocial well-being and health-related quality of life. Results from multiple regression analyses further substantiated these findings, as greater meaningful activity participation was associated with better psychological well-being and health-related quality of life. The MAPA appears to be a reliable and valid measure of meaningful activity, incorporating both subjective and objective indicators of activity engagement. PMID:20649161

    Endometriosis is a puzzling disease characterized by pelvic pain, infertility, allergies, fatigue, and bowel problems. It is a non-lethal medical condition that disables only women and frustrates physicians who are frequently limited in their treatment success. Recently endometriosis has been linked with endocrine, environmental, genetic, and immune factors. The public health impact of endometriosis is significant in terms of suffering, lost income, infertility, stress on families, and medical costs. Resources for endometriosis on the Internet include search engines, medical sources, advocacy sources, U.S. government sources, personal Web sites, public library databases, and social science sources.

Telnet is a system that allows you to log on to a remote computer from anywhere on the Internet and affords access to many useful biomedical sites on the Internet. File transfer protocol (FTP) is a method of transferring files from one computer to another over the Internet. It can be used to download files, including software, from numerous publiclly accessible "anonymous FTP archives" around the world. Such archives can be searched using a tool known as Archie. Network News is a system of electronic discussion groups covering almost every imaginable subject, including many areas of medicine and the biomedical sciences; MOOs are virtual environments that allow real time electronic conferencing and teaching over the Internet. It is difficult to predict the future of medicine on the Internet. However, the net opens up many possibilities not available through previous technologies.
