1980-01-01

The NASA Small Transport Aircraft Technology (STAT) Propulsion Study was established to identify technology requirements and define the research and development required for new commuter aircraft. Interim results of the studies defined mission and design characteristics for 30- and 50-passenger aircraft. Sensitivities were defined that relate changes in engine specific fuel consumption (SFC), weight, and cost (including maintenance) to changes in the aircraft direct operating cost (DOC), takeoff gross weight, and empty weight. A comparison of performance and economic characteristics is presented between aircraft powered by 1980 production engines and those powered by a 1990 advanced technology baseline engine.

1980-01-01

Propulsion requirements were determined for 0.5 and 0.7 Mach aircraft. Sensitivity studies were conducted on both these aircraft to determine parametrically the influence of propulsion characteristics on aircraft size and direct operating cost (DOC). Candidate technology elements and design features were identified and parametric studies conducted to select the STAT advanced engine cycle. Trade off studies were conducted to determine those advanced technologies and design features that would offer a reduction in DOC for operation of the STAT engines. These features were incorporated in the two STAT engines. A benefit assessment was conducted comparing the STAT engines to current technology engines of the same power and to 1985 derivatives of the current technology engines. Research and development programs were recommended as part of an overall technology development plan to ensure that full commercial development of the STAT engines could be initiated in 1988.

2011-01-01

Conceptual Research Corporation, the Science of the Possible, has completed a two-year study of concepts and technologies for future airliners in the 180-passenger class. This NASA-funded contract was primarily focused on the ambitious goal of a 70 percent reduction in fuel consumption versus the market-dominating Boeing 737-800. The study is related to the N+3 contracts awarded in 2008 by NASA s Aeronautics Research Mission Directorate to teams led by Boeing, GE Aviation, MIT, and Northrop Grumman, but with more modest goals and funding. CRC s contract featured a predominant emphasis on propulsion and fuel consumption, but since fuel consumption depends upon air vehicle design as much as on propulsion technology, the study included notional vehicle design, analysis, and parametric studies. Other NASA goals including NOx and noise reduction are of long-standing interest but were not highlighted in this study, other than their inclusion in the propulsion system provided to CRC by NASA. The B-737-800 was used as a benchmark, parametric tool, and design point of departure. It was modeled in the RDS-Professional aircraft design software then subjected to extensive parametric variations of parasitic drag, drag-due-to-lift, specific fuel consumption, and unsized empty weight. These studies indicated that the goal of a 70 percent reduction in fuel consumption could be attained with roughly a 30 percent improvement in all four parameters. The results were then fit to a Response Surface and coded for ease of use in subsequent trade studies. Potential technologies to obtain such savings were identified and discussed. More than 16 advanced concept designs were then prepared, attempting to investigate almost every possible emerging concept for application to this class airliner. A preliminary assessment of these concepts was done based on their total wetted area after design normalization of trimmed maximum lift. This assessment points towards a Tailless Airliner concept which

Marcus, Hani J; Hughes-Hallett, Archie; Kwasnicki, Richard M; Darzi, Ara; Yang, Guang-Zhong; Nandi, Dipankar

2015-07-01

Technological innovation within health care may be defined as the introduction of a new technology that initiates a change in clinical practice. Neurosurgery is a particularly technology-intensive surgical discipline, and new technologies have preceded many of the major advances in operative neurosurgical techniques. The aim of the present study was to quantitatively evaluate technological innovation in neurosurgery using patents and peer-reviewed publications as metrics of technology development and clinical translation, respectively. The authors searched a patent database for articles published between 1960 and 2010 using the Boolean search term "neurosurgeon OR neurosurgical OR neurosurgery." The top 50 performing patent codes were then grouped into technology clusters. Patent and publication growth curves were then generated for these technology clusters. A top-performing technology cluster was then selected as an exemplar for a more detailed analysis of individual patents. In all, 11,672 patents and 208,203 publications related to neurosurgery were identified. The top-performing technology clusters during these 50 years were image-guidance devices, clinical neurophysiology devices, neuromodulation devices, operating microscopes, and endoscopes. In relation to image-guidance and neuromodulation devices, the authors found a highly correlated rapid rise in the numbers of patents and publications, which suggests that these are areas of technology expansion. An in-depth analysis of neuromodulation-device patents revealed that the majority of well-performing patents were related to deep brain stimulation. Patent and publication data may be used to quantitatively evaluate technological innovation in neurosurgery.

Effectiveness of Subsidies in Technology Adoption: A Case Study Involving Reverse Osmosis (RO Membrane Technology

Nur Laili

2016-12-01

Full Text Available Adoption of new technologies is a process that involves technological learning and penetration of new products into the market. Within the process of new technologies adoption, government usually intervened by providing incentives, in order to support the technology adoption to be succeed. This paper examines the effectiveness of incentives for the sustainability of reverse osmosis (RO membrane technology adoption. The study conducted through single case study on SWRO installation in Mandangin Island, East Java, Indonesia. Results of case study indentify the existence of government incentive in the form of direct subsidies to decrease the price of clean water. Although successful in reducing the price of water, but effectiveness of the subsidy on the sustainability of SWRO is still low, which is operates only 30% in a year. Further analysis shows that these subsidies actually be counter-productive to the sustainability of SWRO installation.

international collaboration by describing the globalisation of the economy and current efforts of technology collaboration and transfer. Finally, it considers various ways to strengthen international energy technology collaboration. This paper is one of six case-studies designed in an effort to provide practical insights on the role international technology collaboration could play to achieve the objectives of the UNFCCC. They will all consider the past achievements of international technology collaboration, and the role it could play in helping to develop and disseminate new technologies in the future: what worked, what did not work and why, and what lessons might be drawn from past experiences. Most case studies consider energy technologies that could help mitigate greenhouse gas emissions. A few others consider areas not directly related to greenhouse gas emissions but where international technology collaboration has proven particularly successful in the past. This case study reviews past and current experience in international collaboration in the field of concentrating solar technologies in order to identify lessons that may be relevant for more general climate-friendly technology collaboration. It presents concentrating solar technologies in their current status, recent achievements and development prospects. It analyses the present successes and failures of different forms of international collaboration in this field, and draws lessons for further elaboration of international technology collaboration in addressing climate change.

Technology spin-offs generation – a multicase study

Directory of Open Access Journals (Sweden)

Jonas Mendes Constante

2014-05-01

Full Text Available The objective of this study is to understand how small businesses can innovate through the generation of technological spin-offs, identifying motivations, influences and barriers to achieving this phenomenon. Through a qualitative and exploratory study, we analyzed four cases of technological spin-offs in Santa Catarina State. We collected data through field observations, historical data and semi-structured interviews. The main reasons found for spin-offs creation were: diversification and to complement the value chain of the parent company and to ensure greater focus for a specific technology. The main barrier was lack of capital. Government initiatives to support the creation of new businesses, coupled with the organizational culture open to entrepreneurship and investment in R&D, contributed to the development of spin-offs analyzed. This work contributes to the understanding that small and medium-sized technology-based companies are a source of technological spin-offs and can benefit from the occurrence of this process.

This paper describes elements of success for demonstration, evaluation, and transfer for deployment of innovative technologies for environmental restoration. They have been compiled from lessons learned through the US Department of Energy (DOE) Office of Technology Development's Volatile Organic Compounds in Arid Soil Integrated Demonstration (VOC-Arid ID). The success of the VOC-Arid ID program was determined by the rapid development demonstration, and transfer for deployment of technologies to operational sites that improve on safety, cost, and/or schedule of performance over baseline technologies. The VOC-Arid ID successfully fielded more than 25 innovative technology field demonstrations; several of the technologies demonstrated have been successfully transferred for deployment Field demonstration is a critical element in the successful transfer of innovative technologies into environmental restoration operations. The measures of success for technology demonstrations include conducting the demonstration in a safe and controlled environment and generating the appropriate information by which to evaluate the technology. However, field demonstrations alone do not guarantee successful transfer for deployment There are many key elements throughout the development and demonstration process that have a significant impact on the success of a technology. This paper presents key elements for a successful technology demonstration and transfer for deployment identified through the experiences of the VOC-Arid ID. Also, several case studies are provided as examples

Students' ability of learning is influenced by study habits. Among these, the use of technologies has assumed a controversial role. The aim of this paper is to analyse studying approach, the use of technologies and how they affect study habits in a population of university students addressed by the "Sportello Salute Giovani" ("Youth Health Information Desk") questionnaire. 16 questions referred to the approach to studying and the use of technologies (number 77-93) were analyzed. Absolute and relative frequencies were calculated. Stratification for sex, age and socio-economic status were performed and Chi square test was used to test the difference between sex, age class and socio-economic groups. 99.7% of students declared to have at least one mobile phone and 68.7% to use smartphones, i-phones and i-pads. Males (20.9% vs 14.9% female, p students (31.7% among 25-30 years old students vs 21.3% among 18-21 years old, p students with the highest socio-economic level (87.8% vs 54.2% of the lowest) seem more likely to use digital technologies/Internet for educational purposes. Our survey revealed that most college students still prefer approach the study using books instead of digital tools, but this attitude is conflicting with how many hours they use computers and surf Internet per weeks. Therefore, further studies are needed to understand better technology influence on study habits and its implication on health.

Technology as a Time Challenge: Study, Concept and Types of Technology

2017-09-01

Full Text Available In the article divorce the concepts of engineering and technology. Designated four stages of technological development: the fi rst phase — “pilot technique”, it is characterized by magical conceptualization, the second — engineering (rational conceptualization, third design, fourth technology. For technical equipment is characterized by four features: technology is the artifacts, the technique can be considered as a “social body” of a person or society, technology is a useful way to use the forces of nature, and fi nally, the mediation in the form of tools, machines, and material environment that allows you to implement the ideas of man. It is argued that the conceptualization of technology is the essential characteristic of the concept. If you write, for example, about the technology of the Neolithic age or era of construction of the Egyptian pyramids, then we are talking about retrospective interpretation, from the point of view of modern understanding of technology. It’s not useless, for example, to determine preconditions of formation technology, but in terms of thinking creates problems and contradictions. The author argues that technology develops in the second half of the eighteenth century as a new reality, which describes the industrial activities in language operations and their conditions of division of labor and management. At the same time, technology is being characterized by the installation of quality, savings, standardization, and rational description of the production processes, their optimization for the training of new technologists. Discusses three stages of development of the technology and features of the main types of technology: production technology, engineering, large techno-social projects, global technology.

Innovation of medical technology is a major driving force behind the increase in medical expenditures in developed countries. Previous studies identified that the diffusion of medical technology varied across countries according to the characteristics of regulatory policy and payment systems. Based on Roger's diffusion of innovation theory, this study purported to see how local practice norms, the evolving nature of diffusing technology, and local clinical needs in addition to differences in politico-economic systems would affect the process of innovation diffusion. Taking a case of coronary stenting, an innovative therapeutic technology in early 1990s, we provided a case study of hospital-based data between two teaching high-tech hospitals in Japan and the US for discussion. Stenting began to be widely used in both countries when complementary new technology modified its clinical efficacy, but the diffusion process still differed between the two hospitals due to (1) distinctive payment systems for hospitals and physicians, (2) practice norms in favor of percutaneous intervention rather than bypass surgery that was shaped by payment incentives and cultural attitudes, and (3) local patient's clinical characteristics that the technology had to be tailored for. The case study described the diffusion of stent technology as a dynamic process between patients, physicians, hospitals, health care systems, and technology under global and local conditions.

The Advanced Fuel Cycle Initiative (AFCI) Safeguards Campaign aims to develop safeguards technologies and processes that will significantly reduce the risk of proliferation in the U.S. nuclear fuel cycle of tomorrow. The Safeguards Enhancement Study was chartered with identifying promising research and development (R&D) directions over timescales both near-term and long-term, and under safeguards oversight both domestic and international. This technology development roadmap documents recognized gaps and needs in the safeguarding of nuclear fuel cycles, and outlines corresponding performance targets for each of those needs. Drawing on the collective expertise of technologists and user-representatives, a list of over 30 technologies that have the potential to meet those needs was developed, along with brief summaries of each candidate technology. Each summary describes the potential impact of that technology, key research questions to be addressed, and prospective development milestones that could lead to a definitive viability or performance assessment. Important programmatic linkages between U.S. agencies and offices are also described, reflecting the emergence of several safeguards R&D programs in the U.S. and the reinvigoration of nuclear fuel cycles across the globe.

Full Text Available This paper shows the results of studying the technology of manufacturing cortical electrode-instruments (EI with the use of indirect methods of the Rapid Prototyping technology. Functional EI prototypes were made by layered synthesis of the photopolymer material with the use of the stereolithography technology (SLA - Stereo Lithography Apparatus. The article is focused on two methods of indirect EI manufacturing. One of the EI prototypes was used for making a molded wax model for hot investment casting, followed by applying copper coating. The second prototype was used for applying copper plating to a prepared current-conductive layer. As a result of EDMing a steel workpiece, both EIs reached the desired depth, which is 1 mm.

Full Text Available BACKGROUND: Students' ability of learning is influenced by study habits. Among these, the use of technologies has assumed a controversial role. The aim of this paper is to analyse studying approach, the use of technologies and how they affect study habits in a population of university students addressed by the "Sportello Salute Giovani" ("Youth Health Information Desk" questionnaire. METHODS: 16 questions referred to the approach to studying and the use of technologies (number 77-93 were analyzed. Absolute and relative frequencies were calculated. Stratification for sex, age and socio-economic status were performed and Chi square test was used to test the difference between sex, age class and socio-economic groups. RESULTS: 99.7% of students declared to have at least one mobile phone and 68.7% to use smartphones, i-phones and i-pads. Males (20.9% vs 14.9% female, p < 0.05, older students (31.7% among 25-30 years old students vs 21.3% among 18-21 years old, p < 0.05 and students with the highest socio-economic level (87.8% vs 54.2% of the lowest seem more likely to use digital technologies/Internet for educational purposes. CONCLUSION: Our survey revealed that most college students still prefer approach the study using books instead of digital tools, but this attitude is conflicting with how many hours they use computers and surf Internet per weeks. Therefore, further studies are needed to understand better technology influence on study habits and its implication on health.

Full Text Available The paper discusses topical issues of virtual reality technologies in social research, particularly when studying the processes of ethnic cultural identity, development of ethnic and racial attitudes using «virtual avatars» for managing ethnic conflicts, development of communication skills in representatives of different cultures using virtual collaboration and video conferencing. One of the key issues of the paper to discuss the necessity of post-non-classical paradigm as a conceptual framework for social research. Contemporary social studies require developing new methods, technologies and techniques at all levels of the research: from task setting to the development of new methods and result analysis. One of the most promising methods rapidly developed in recent years is virtual reality technology. The paper presents the analysis of more than 40 experimental studies performed using CAVE and HMD virtual reality systems. Their application is considered hereunder for the studies of verbal and nonverbal cues in communication, social skills training, treatment of social anxiety disorders and the development of new methods of cognitive behavioural therapy. Studies on interpersonal communication with virtual partners (i.e. «avatars» are considered. Factors affecting the communication quality of avatars, its visual and behavioural realism, problems of seeing virtual human as real partners for social interaction are discussed. Special attention is paid to the studies of racial and ethnic attitudes performed using virtual reality systems. The possibilities of practical applications of the VR technologies for shaping positive attitudes and development of communication skills in a sociocultural context are emphasized.

Gnanakkan, Dionysius Joseph

This multiple case-study investigated how high school biology teachers used modern learning technologies (probes, interactive simulations and animations, animated videos) in their classrooms and why they used the learning technologies. Another objective of the study was to assess whether the use of learning technologies alleviated misconceptions in Biology documented by American Association for the Advancement of Science. The sample consisted of eight teachers: four rural public school teachers, two public selective enrollment school teachers, and two private school teachers. Each teacher was followed for two Units of instruction. Data collected included classroom observations, field notes, student assignments and tests, teacher interviews, and pre-and post-misconception assessments. Paired t-tests were done to analyze the pre-post test data at a significance level of 0.05 and the qualitative data was analyzed using the constant comparative method. Each case study was characterized and then a cross-case analyses was done to find common themes across the different cases. Teachers were found to use the learning technologies as a tool to supplement instruction to visualize abstract processes, collect data, and explore abstract concepts and processes. Teachers were found to situate learning, use scaffolding and questioning and make students work in collaborative groups. The genetics, photosynthesis, and evolution misconceptions were better alleviated than cellular respiration. Student work that was collected demonstrated a superficial understanding of the concepts under discussion even when they had misconceptions. The teachers used the learning technologies in their classrooms for a variety of reasons: visual illustrations, time-saving measure to collect data, best way to collect data, engaging and fun for students and the interactive nature of the visualization tools and models. The study's findings had many implications for research, professional development

Abdullah Konak

2016-12-01

Findings\tThe findings of the study supported that collaborative work could improve non-technology students’ acceptance of RVCLs. However, no significant effect of collaborative work on technology acceptance was observed in the case of technology students. Recommendations for Practitioners\tEducators should consider the benefits of collaborative work while introducing a new technology to students who may not have background in the technology introduced. Recommendation for Researchers In this study, student technological background was found to be a significant factor for technology acceptance; hence, it is recommended that technological background is included in TAM studies as an external factor. Future Research\tRepeating similar studies with multiple exercises with varying degrees of challenge is required for a better understanding of how collaborative work and student technological background affect technology acceptance.

2011-01-01

Studies show that the student population (secondary and post secondary) is becoming increasingly more technologically savvy. Use of the internet, computers, MP3 players, and other technologies along with online gaming has increased tremendously amongst this population such that it is creating an apparent paradigm shift in the learning modalities of these students. Instructors and facilitators of learning can no longer rely solely on traditional lecture-based lesson formals. In order to achieve student academic success and satisfaction and to increase student retention, instructors must embrace various technology tools that are available and employ them in their lessons. A longitudinal study (January 2009-June 2010) has been performed that encompasses the use of several technology tools in an instructional setting. The study provides further evidence that students not only like the tools that are being used, but prefer that these tools be used to help supplement and enhance instruction.

Proteomic Technologies for the Study of Osteosarcoma

Directory of Open Access Journals (Sweden)

Stephanie D. Byrum

2012-01-01

Full Text Available Osteosarcoma is the most common primary bone cancer of children and is established during stages of rapid bone growth. The disease is a consequence of immature osteoblast differentiation, which gives way to a rapidly synthesized incompletely mineralized and disorganized bone matrix. The mechanism of osteosarcoma tumorogenesis is poorly understood, and few proteomic studies have been used to interrogate the disease thus far. Accordingly, these studies have identified proteins that have been known to be associated with other malignancies, rather than being osteosarcoma specific. In this paper, we focus on the growing list of available state-of-the-art proteomic technologies and their specific application to the discovery of novel osteosarcoma diagnostic and therapeutic targets. The current signaling markers/pathways associated with primary and metastatic osteosarcoma that have been identified by early-stage proteomic technologies thus far are also described.

The report documents a study which compares 12 different technologies for gas power plants with CO 2 handling. The additional costs in removing the CO 2 in connection with electricity production is calculated to at least 18-19 oere /kWh compared to conventional gas power production without CO 2 capture. The calculated extra costs are somewhat higher than previously published figures. The difference is mainly due to that the estimated costs for pipelines and injection system for CO 2 are higher than in other studies. The removal of CO 2 in connection with gas power production implies increased use of natural gas. The most developed technologies would lead to a procentual increase in the gas consumption per kWh electricity of 18-25%. Gas power plants based on the present technologies would have efficiencies in the size of 46-49%. The efficiency of power plants without CO 2 handling is supposed to be 58%. There is no foundation for pointing out a ''winner's' among the compared technologies in the study. The present available technologies excepted, there are no technology which stands out as better than the others from an economic viewpoint. Gas turbine with membrane based separation of oxygen from air (AZEP) has a potential for lower costs but implies challenging technological development and thence considerable technological risks. Two technologies, capture of carbon from natural gas previous to combustion and exhaust gas purification based on absorption, may be employed in 3 - 4 years. The other technologies require more development and maturing. Three of the technologies may be particularly interesting because hydrogen may be produced as a byproduct. Demonstration plant and choice of technology: 1) There is a limited need for demonstration plants with respect to technology development. 2) It is important for the technology development to be able to test various technologies in a laboratory or in a flexible pilot plant. 3) Many technologies and components may be

Remote monitoring technologies are ideally suited for rural communities with limited access to health care. In an 8-week pilot study, we examined the feasibility of implementing and conducting a technology-intensive intervention in an underserviced rural setting. Our goal was to test the utility of self-monitoring technologies, physical activity, and education as tools to manage health indicators for the development of the cardiovascular complications (CVCs) of type 2 diabetes. The Diabetes and Technology for Increased Activity study was an open single-center study conducted in a community-based research setting. All 24 participants were provided with a Blackberry™ Smartphone, blood pressure monitor, glucometer, and pedometer. Smartphones transmitted measurements and survey results to the database, interfaced participants with the clinical team, and allowed for self-monitoring. Outcomes were improved body composition, improved markers of CVC risk factors, increased daily exercise, and interest in or awareness of lifestyle changes that impact health outcomes. Participants had excellent compliance for measurements, as self-monitoring provided a sense of security that improved from week 4 to week 8. Our team gained substantial insight into the operational requirements of technology-facilitated health care, including redefined hours of service; data reporting, management, and access protocols; and the utility of real-time clinical measures by remote monitoring. We developed an understanding of knowledge translation strategies as well as successful motivational and educational tools. Importantly, remote monitoring technology was found to be feasible and accepted in a rural setting. © 2011 Diabetes Technology Society.

2013-08-01

Full Text Available One of the most dominant features of a classroom space is its high occupancy, which results in high internal heat gain (approximately 5 KW. Furthermore, installation of educational technologies, such as smart boards, projectors and computers in the spaces increases potential internal heat gain. Previous studies on office buildings indicate that with the introduction of IT equipment in spaces during the last decade, cooling load demands are increasing with an associated increase in summer electrical demand. Due to the fact that educational technologies in specific correspond to pedagogical practices within the space, a lot of variations due to occupancy patterns occur. Also, thermal loads caused by educational technologies are expected to be dependent on spatial configuration, for example, position with respect to the external walls, lighting equipment, mobility of devices. This study explores the thermal impact of educational technologies in 2 typical educational spaces in a facility of higher education; the classroom and the computer lab. The results indicate that a heat gain ranging between 0.06 and 0.095 KWh/m2 is generated in the rooms when educational technologies are in use. The second phase of this study is ongoing, and investigates thermal zones within the rooms due to distribution of educational technologies. Through simulation of thermal performance of the rooms, alternative room configurations are thus recommended in response to the observed thermal zones.

Full Text Available Technology-enhanced multimedia instruction offers benefits for foreign language learners. Despite having much potential, technology itself is neither effective or nor effective, but teachers play a key role in determining its effectiveness because they are in charge of making instructional decisions and choose whether and how to use technology. This article fills a gap in the literature by reporting findings of a mixed methods study of technology- enhanced multimedia instruction in middle and high school foreign language classrooms. Convergent parallel mixed methods design was applied in this study and data was collected through quantitative survey and qualitative semi-structured interviews with teachers. Results from the study indicated a significant positive correlation between variables that contribute to the use of technology-enhanced multimedia instruction in foreign language classrooms and described effective technology-enhanced multimedia practices. The findings of the study have implications for teachers, administrators and faculty of teacher preparation programs as well as state teacher education policy makers.

Composite structures have the potential to be cost-effective, structurally efficient primary aircraft structures. The Advanced Composites Technology (ACT) Program has the goal to develop the technology to exploit this potential for heavily loaded aircraft structures. As part of the ACT Program, Lockheed Aeronautical Systems Company completed the design and fabrication of the Technology Integration Box Beam (TIBB). The TIBB is an advanced composite prototype structure for the center wing section of the C-130 aircraft. Lockheed subjected the TIBB to downbending, upbending, torsion and combined upbending and torsion load conditions to verify the design. The TIBB failed at 83 percent of design ultimate load for the combined upbending and torsion load condition. The objective of this paper is to describe the mechanisms that led to the failure of the TIBB. The results of a comprehensive analytical and experimental study are presented. Analytical results include strain and deflection results from both a global analysis of the TIBB and a local analysis of the failure region. These analytical results are validated by experimental results from the TIBB tests. The analytical and experimental results from the TIBB tests are used to determine a sequence of events that resulted in failure of the TIBB. A potential cause of failure is high stresses in a stiffener runout region. Analytical and experimental results are also presented for a stiffener runout specimen that was used to simulate the TIBB failure mechanisms.

Numerous organizations have published reports in recent years that investigate the ever changing world of electric vehicle (EV) technologies and their potential effects on society. Specifically, projections have been made on greenhouse gas (GHG) emissions associated with these vehicles and how they compare to conventional vehicles or hybrid electric vehicles (HEVs). Similar projections have been made on the volumes of oil that these vehicles can displace by consuming large amounts of grid electricity instead of petroleum-based fuels. Finally, the projected rate that these new vehicle fleets will enter the market varies significantly among organizations. New ideas, technologies, and possibilities are introduced often, and projected values are likely to be refined as industry announcements continue to be made. As a result, over time, a multitude of projections for GHG emissions, oil displacement, and market penetration associated with various EV technologies has resulted in a wide range of possible future outcomes. This leaves the reader with two key questions: (1) Why does such a collective range in projected values exist in these reports? (2) What assumptions have the greatest impact on the outcomes presented in these reports? Since it is impractical for an average reader to review and interpret all the various vehicle technology reports published to date, Sentech Inc. and the Oak Ridge National Laboratory have conducted a comparative study to make these interpretations. The primary objective of this comparative study is to present a snapshot of all major projections made on GHG emissions, oil displacement, or market penetration rates of EV technologies. From the extensive data found in relevant publications, the key assumptions that drive each report's analysis are identified and 'apples-to-apples' comparisons between all major report conclusions are attempted. The general approach that was taken in this comparative study is comprised of six primary

Full Text Available The book starts with an explanation of the reason why the terms found in the book are sometimes used in place of each other. The editors stated that when technological tools are used to establish an effective and productive study process in education, the concept of learning technology is used instead of educational technology. The editors of the book considers the field as complex and vague in terms of the fact that the meanings of the concepts are close to each other in the field of educational technology and that the field provides an opportunity for inter-disciplinary studies. However, according to the editors, this vagueness and complexity shows the superiority of the field. This superiority is explained with the fact that the field of educational technology requires upper-level skills of problem solving and critical thinking and that it presents a multi-dimensional and inter-disciplinary study field.

1980-01-01

Data and information in the area of advanced energy conversion systems for industrial congeneration applications in the 1985-2000 time period was studied. Six current and thirty-one advanced energy conversion systems were defined and combined with appropriate balance-of-plant equipment. Twenty-six industrial processes were selected from among the high energy consuming industries to serve as a framework for the study. Each conversion system was analyzed as a cogenerator with each industrial plant. Fuel consumption, costs, and environmental intrusion were evaluated and compared to corresponding traditional values. Various cogeneration strategies were analyzed and both topping and bottoming (using industrial by-product heat) applications were included. The advanced energy conversion technologies indicated reduced fuel consumption, costs, and emissions. Typically fuel energy savings of 10 to 25 percent were predicted compared to traditional on-site furnaces and utility electricity. With the variety of industrial requirements, each advanced technology had attractive applications. Overall, fuel cells indicated the greatest fuel energy savings and emission reductions. Gas turbines and combined cycles indicated high overall annual cost savings. Steam turbines and gas turbines produced high estimated returns. In some applications, diesels were most efficient. The advanced technologies used coal-derived fuels, or coal with advanced fluid bed combustion or on-site gasification systems.

The broad use of mobile technologies supports the need for usability assessments of these tools. Although there have been a number of usability assessment instruments developed, none have been validated for use with mobile technologies. The goal of this work was to validate the Health Information Technology Usability Evaluation Scale (Health-ITUES), a customizable usability assessment instrument in a sample of community-dwelling adults who were testing the use of a new mobile health (mHealth) technology. A sample of 92 community-dwelling adults living with HIV used a new mobile app for symptom self-management and completed the Health-ITUES to assess the usability of the app. They also completed the Post-Study System Usability Questionnaire (PSSUQ), a widely used and well-validated usability assessment tool. Correlations between these scales and each of the subscales were assessed. The subscales of the Health-ITUES showed high internal consistency reliability (Cronbach alpha=.85-.92). Each of the Health-ITUES subscales and the overall scale was moderately to strongly correlated with the PSSUQ scales (r=.46-.70), demonstrating the criterion validity of the Health-ITUES. The Health-ITUES has demonstrated reliability and validity for use in assessing the usability of mHealth technologies in community-dwelling adults living with a chronic illness. ©Rebecca Schnall, Hwayoung Cho, Jianfang Liu.

Jianghua Zhou

2017-01-01

Full Text Available Building on a case study of five Chinese solar thermal companies and one association, our study aims to understand how the innovator’s choices regarding the use of technology and organizational practices for new product development enable companies to design and diffuse appropriate technology in emerging markets. The study uncovers two critical factors that enhance the appropriateness of technology: redefining the identity of technology and building a local supply system. Our analysis shows that synergic innovation in both architecture and component leads to the appropriate functionalities desired by emerging markets. Moreover, modular design and the building of a local supply system enhance the process appropriateness of technology. Our study provides an empirical basis for advocating going beyond minor adaptations of existing products to creating appropriate technology for emerging markets, and extends our understandings of the upstream process of designing appropriate technology. Moreover, the emphasis on the local supply system reflects a holistic framework for shaping and delivering appropriate technology, expanding the existing research focus on the perspective of the technology itself. Our research also has managerial implications that may help firms tap into emerging markets.

The objective of this study is to devise a proper measure for international publicity and technology export strategy. Analysed and summaries in detail are other countries nuclear policy trend and the current technology development status of Korea Standard Nuclear Plant that we developed on our own technology, design and construction technology for research reactor, System-integrated Modular Advanced Reactor of which design is in progress, Direct use of Spent PWR Fuel in CANDU Reactors, and Radioisotopes. Based on that, the measures are proposed for the export industrialization of nuclear technology and establishment of the export basis. Also the international nuclear cooperation and publicity strategy are suggested to support the technology export basis. By surveying the world nuclear status, the direction for the international cooperation and publicity is settled and the specific publicity strategy is proposed for the cooperation with IAEA and multi-countries and the establishment of the nuclear technology export basis. As part of this project, the panel on major technologies such as Korea Standard Nuclear Plant, HANARO, and System-integrated Modular Advanced Reactor was displayed successfully at the IAEA meeting, which contribute much to the publicity of our nuclear technology to the international nuclear society.

Cost decreases in environmental technology. Evidence from four case studies

Energy Technology Data Exchange (ETDEWEB)

Oosterhuis, F. [Instituut for Environmental Studies, Vrije Universiteit VU, Amsterdam (Netherlands)

2007-07-15

The cost of a new technology tends to decrease as its uptake grows, and environmental technology is no exception to this general rule. Factors that can bring about such cost reductions include economies of scale, 'learning-by-doing', incremental technological improvements, and growing competition. In preparing environmental policies, the potential for future cost reductions is often disregarded. The present study aims to provide some additional empirical evidence on the cost decreases in environmental technology and the factors that lie behind them. To this end, four exemplary case studies have been selected. The first case (NOx emission abatement by Selective Catalytic Reduction (SCR)), shows a wide variety in cost estimates, without a clear trend. This is even true for the costs of a fairly homogeneous type of investment (SCR in coal fired power plants). Nevertheless, it is clear that an important cost decrease has been achieved by prolonging the lifetime of the catalyst, which is one of the main cost components in SCR. In the second case (NH3 emission abatement by chemical air scrubbers in pig farming) there is not yet sufficient experience with the technology to draw conclusions on the development of costs. However, it is already clear that economizing on the capacity of the system can contribute to important cost savings. Three-way catalytic converters in cars have shown significant price decreases following their large scale introduction on the European market in the early 1990s. Probably economies of scale have played an important role in this case, as the size of the market made mass production possible. To some extent, cost reductions may also be attributed to improvements such as the need for less materials (e.g. platinum). Furthermore, the performance of catalytic converters has improved, implying that the cost per unit of emission reduction has decreased even more than the cost of the device itself.

Hurdling barriers through market uncertainty: Case studies ininnovative technology adoption

Energy Technology Data Exchange (ETDEWEB)

Payne, Christopher T.; Radspieler Jr., Anthony; Payne, Jack

2002-08-18

The crisis atmosphere surrounding electricity availability in California during the summer of 2001 produced two distinct phenomena in commercial energy consumption decision-making: desires to guarantee energy availability while blackouts were still widely anticipated, and desires to avoid or mitigate significant price increases when higher commercial electricity tariffs took effect. The climate of increased consideration of these factors seems to have led, in some cases, to greater willingness on the part of business decision-makers to consider highly innovative technologies. This paper examines three case studies of innovative technology adoption: retrofit of time-and-temperature signs on an office building; installation of fuel cells to supply power, heating, and cooling to the same building; and installation of a gas-fired heat pump at a microbrewery. We examine the decision process that led to adoption of these technologies. In each case, specific constraints had made more conventional energy-efficient technologies inapplicable. We examine how these barriers to technology adoption developed over time, how the California energy decision-making climate combined with the characteristics of these innovative technologies to overcome the barriers, and what the implications of hurdling these barriers are for future energy decisions within the firms.

A longitudinal study on boys' and girls' career aspirations and interest in technology

Science.gov (United States)

Ardies, Jan; De Maeyer, Sven; Gijbels, David

2015-09-01

Background: More young people, boys and girls, are needed in technical studies and professions, as the relative number of students in technology-related studies has been decreasing in most industrialised countries. To overcome this decrease several countries implemented mandatory technology classes in the curriculum of secondary education. Purpose: This study has two goals: exploring the evolution of pupils' interest during the year(s) they attend the mandatory technology classes and exploring determining characteristics for differences in boys' and girls' attitude change over time. Sample: This study focuses on data gathered in the first and second grade of the first cycle in general secondary education in the North region of Belgium, Flanders. In a first stage we selected a good representation of geographically spread schools (n = 20), from which over 1300 students participated. Design and methods: A longitudinal study with eight measurement occasions spread over the course of two years is presented in order to capture the evolution of students' attitudes, making use of a multilevel growth model analysis. Results: The results show that students' interest in technology decreases over time, although at the end of each grade interest is increasing again. Boys' and girls' interest in technology also evolves a little different in the first cycle of secondary education. For career aspirations we didn't see any significant difference between boys and girls. Boys' and girls' aspirations decrease over time with a little increase by the end of the second grade. Students with a more technological curriculum also have more career aspirations in the field of technology than their peers with other curricula. Although students' perceptions about technology as a subject for boys and girls are largely stable. Conclusions: The evolution of students' attitude is far from linear, this strengthens us in the choice for a more complex analysis model and the choice for more measuring

A cultural study of a science classroom and graphing calculator-based technology

Science.gov (United States)

Casey, Dennis Alan

Social, political, and technological events of the past two decades have had considerable bearing on science education. While sociological studies of scientists at work have seriously questioned traditional histories of science, national and state educational systemic reform initiatives have been enacted, stressing standards and accountability. Recently, powerful instructional technologies have become part of the landscape of the classroom. One example, graphing calculator-based technology, has found its way from commercial and domestic applications into the pedagogy of science and math education. The purpose of this study was to investigate the culture of an "alternative" science classroom and how it functions with graphing calculator-based technology. Using ethnographic methods, a case study of one secondary, team-taught, Environmental/Physical Science (EPS) classroom was conducted. Nearly half of the 23 students were identified as students with special education needs. Over a four-month period, field data was gathered from written observations, videotaped interactions, audio taped interviews, and document analyses to determine how technology was used and what meaning it had for the participants. Analysis indicated that the technology helped to keep students from getting frustrated with handling data and graphs. In a relatively short period of time, students were able to gather data, produce graphs, and to use inscriptions in meaningful classroom discussions. In addition, teachers used the technology as a means to involve and motivate students to want to learn science. By employing pedagogical skills and by utilizing a technology that might not otherwise be readily available to these students, an environment of appreciation, trust, and respect was fostered. Further, the use of technology by these teachers served to expand students' social capital---the benefits that come from an individual's social contacts, social skills, and social resources.

Wan Nooraishya Wan Ahmad

2018-06-01

Full Text Available A successful persuasive technology is able to persuade people to change from one state to a more well known state. Therefore, to allow for a change, persuasive technology must be able to affect users’ emotion and make the user trust the technology so that they will adopt the persuasive technology into their daily life routine, as well as continue to use the technology for long period. This paper is aimed to study the relation between users’ emotion with trust and persuasion and how they may contribute to the success of changing a person attitude or behavior towards a certain context or issue. Twenty five participants have completed the study in 6 weeks by using two types of persuasive technology that were assessed at three different interaction stages: pre, during and post. Result shows that emotions have a significant effect on trust, whereas the effect of emotions on persuasion using the persuasive technology was mediated by trust.

Introduction to the study of solar technology

Energy Technology Data Exchange (ETDEWEB)

Touchais, M

1979-01-01

The conversion of solar energy to meet the world's energy requirements by means of solar technology is discussed as preface to an introductory course in solar technology. The significance of the energy crisis of 1973 to the development of alternative sources of energy, primarily solar, is considered, and the amount of recoverable solar energy incident on the earth is estimated to be able to supply the world's energy demand. The various means of solar energy conversion, including thermal, chemical in the form of hydrogen or methane, and direct or thermal electrical, are examined, and areas of these technologies requiring further experimental investigation are indicated. Solar technology is presented as the science of the artificial applications of solar energy, with mention of its associated disciplines, and the deficiencies of the solar technology developed prior to the energy crisis are exposed. Goals for contemporary instruction in solar technology are then derived, the introductory course is outlined, and bibliographic references are presented. Differences between the sources of solar and traditional energies are also discussed.

Lung, For-Wey; Chiang, Tung-Liang; Lin, Shio-Jean; Lee, Meng-Chih; Shu, Bih-Ching

2018-04-01

The use of assisted reproduction technology has increased over the last two decades. Autism spectrum disorders and assisted reproduction technology share many risk factors. However, previous studies on the association between autism spectrum disorders and assisted reproduction technology have shown inconsistent results. The purpose of this study was to investigate the association between assisted reproduction technology and autism spectrum disorder diagnosis in a national birth cohort database. Furthermore, the results from the assisted reproduction technology and autism spectrum disorder propensity score matching exact matched datasets were compared. For this study, the 6- and 66-month Taiwan Birth Cohort Study datasets were used (N = 20,095). In all, 744 families were propensity score matching exact matched and selected as the assisted reproduction technology sample (ratio of assisted reproduction technology to controls: 1:2) and 415 families as the autism spectrum disorder sample (ratio of autism spectrum disorder to controls: 1:4). Using a national birth cohort dataset, controlling for the confounding factors of assisted reproduction technology conception and autism spectrum disorder diagnosis, both assisted reproduction technology and autism spectrum disorder propensity score matching matched datasets showed the same results of no association between assisted reproduction technology and autism spectrum disorder. Further study on the detailed information regarding the processes and methods of assisted reproduction technology may provide us with more information on the association between assisted reproduction technology and autism spectrum disorder.

Renewable energy technology portfolio planning with scenario analysis: A case study for Taiwan

International Nuclear Information System (INIS)

Chen, T.-Y.; Yu, Oliver S.; Hsu, George Jyh-yih; Hsu, Fang-Ming; Sung, W.-N.

2009-01-01

This paper presents the results of a case study of applying a systematic and proven process of technology portfolio planning with the use of scenario analysis to renewable energy developments in Taiwan. The planning process starts with decision values of technology development based on a survey of society leaders. It then generates, based on expert opinions and literature search, a set of major technology alternatives, which in this study include: wind energy, photovoltaic, bio-energy, solar thermal power, ocean energy, and geothermal energy. Through a committee of technical experts with diversified professional backgrounds, the process in this study next constructs three scenarios ('Season in the Sun', 'More Desire than Energy', and 'Castle in the Air') to encompass future uncertainties in the relationships between the technology alternatives and the decision values. Finally, through a second committee of professionals, the process assesses the importance and risks of these alternative technologies and develops a general strategic plan for the renewable energy technology portfolio that is responsive and robust for the future scenarios. The most important contributions of this paper are the clear description of the systematic process of technology portfolio planning and scenario analysis, the detailed demonstration of their application through a case study on the renewable energy development in Taiwan, and the valuable results and insights gained from the application.

Information data systems for a global change technology initiative architecture trade study

Science.gov (United States)

Murray, Nicholas D.

1991-01-01

The Global Change Technology Initiative (GCTI) was established to develop technology which will enable use of satellite systems of Earth observations on a global scale, enable use of the observations to predictively model Earth's changes, and provide scientists, government, business, and industry with quick access to the resulting information. At LaRC, a GCTI Architecture Trade Study was undertaken to develop and evaluate the architectural implications to meet the requirements of the global change studies and the eventual implementation of a global change system. The output of the trade study are recommended technologies for the GCTI. That portion of the study concerned with the information data system is documented. The information data system for an earth global change modeling system can be very extensive and beyond affordability in terms of today's costs. Therefore, an incremental approach to gaining a system is most likely. An options approach to levels of capability versus needed technologies was developed. The primary drivers of the requirements for the information data system evaluation were the needed science products, the science measurements, the spacecraft orbits, the instruments configurations, and the spacecraft configurations and their attendant architectures. The science products requirements were not studied here; however, some consideration of the product needs were included in the evaluation results. The information data system technology items were identified from the viewpoint of the desirable overall information system characteristics.

Cost studies of thermally enhanced in situ soil remediation technologies

International Nuclear Information System (INIS)

Bremser, J.; Booth, S.R.

1996-05-01

This report describes five thermally enhanced technologies that may be used to remediate contaminated soil and water resources. The standard methods of treating these contaminated areas are Soil Vapor Extraction (SVE), Excavate ampersand Treat (E ampersand T), and Pump ampersand Treat (P ampersand T). Depending on the conditions at a given site, one or more of these conventional alternatives may be employed; however, several new thermally enhanced technologies for soil decontamination are emerging. These technologies are still in demonstration programs which generally are showing great success at achieving the expected remediation results. The cost savings reported in this work assume that the technologies will ultimately perform as anticipated by their developers in a normal environmental restoration work environment. The five technologies analyzed in this report are Low Frequency Heating (LF or Ohmic, both 3 and 6 phase AC), Dynamic Underground Stripping (DUS), Radio Frequency Heating (RF), Radio Frequency Heating using Dipole Antennae (RFD), and Thermally Enhanced Vapor Extraction System (TEVES). In all of these technologies the introduction of heat to the formation raises vapor pressures accelerating contaminant evaporation rates and increases soil permeability raising diffusion rates of contaminants. The physical process enhancements resulting from temperature elevations permit a greater percentage of volatile organic compound (VOC) or semi- volatile organic compound (SVOC) contaminants to be driven out of the soils for treatment or capture in a much shorter time period. This report presents the results of cost-comparative studies between these new thermally enhanced technologies and the conventional technologies, as applied to five specific scenarios

Proserpio, Valentina; Mahata, Bidesh

2016-02-01

The immune system is composed of a variety of cells that act in a coordinated fashion to protect the organism against a multitude of different pathogens. The great variability of existing pathogens corresponds to a similar high heterogeneity of the immune cells. The study of individual immune cells, the fundamental unit of immunity, has recently transformed from a qualitative microscopic imaging to a nearly complete quantitative transcriptomic analysis. This shift has been driven by the rapid development of multiple single-cell technologies. These new advances are expected to boost the detection of less frequent cell types and transient or intermediate cell states. They will highlight the individuality of each single cell and greatly expand the resolution of current available classifications and differentiation trajectories. In this review we discuss the recent advancement and application of single-cell technologies, their limitations and future applications to study the immune system. © 2015 The Authors.

This report provides projected cost and performance assumptions for electric technologies considered in the Electrification Futures Study, a detailed and comprehensive analysis of the effects of widespread electrification of end-use service demands in all major economic sectors - transportation, residential and commercial buildings, and industry - for the contiguous United States through 2050. Using extensive literature searches and expert assessment, the authors identify slow, moderate, and rapid technology advancement sensitivities on technology cost and performance, and they offer a comparative analysis of levelized cost metrics as a reference indicator of total costs. The identification and characterization of these end-use service demand technologies is fundamental to the Electrification Futures Study. This report, the larger Electrification Futures Study, and the associated data and methodologies may be useful to planners and analysts in evaluating the potential role of electrification in an uncertain future. The report could be broadly applicable for other analysts and researchers who wish to assess electrification and electric technologies.

At the request of the U.S. Department of Energy Office of River Protection, Pacific Northwest National Laboratory (PNNL) conducted a scoping study to investigate supplemental technologies for supplying vertical fluid motion and enhanced mixing in Waste Treatment and Immobilization Plant (WTP) vessels designed for high solids processing. The study assumed that the pulse jet mixers adequately mix and shear the bottom portion of a vessel. Given that, the primary function of a supplemental technology should be to provide mixing and shearing in the upper region of a vessel. The objective of the study was to recommend a mixing technology and configuration that could be implemented in the 8-ft test vessel located at Mid-Columbia Engineering (MCE). Several mixing technologies, primarily airlift circulator (ALC) systems, were evaluated in the study. This technical report contains a review of ALC technologies, a description of the PNNL testing and accompanying results, and recommended features of an ALC system for further study.

Technology study of Gunite tank sludge mobilization at Oak Ridge National Laboratory, Oak Ridge, Tennessee

DeVore, J.R.; Herrick, T.J.; Lott, K.E.

1994-12-01

The Oak Ridge National Laboratory (ORNL) Gunite Tank Sludge Mobilization Technology Study was initiated to support the Gunite Tank Treatability Study effort. The technology study surveyed the methods and technologies available for tank cleaning and sludge mobilization in a radioactive environment. Technologies were identified and considered for applicability to the Gunite and Associated Tanks (GAAT) problems. These were then either accepted for further study or rejected as not applicable. Technologies deemed applicable to the GAAT sludge removal project were grouped for evaluation according to (1) deployment method, (2) types of remotely operated end effector equipment applicable to removal of sludge, (3) methods for removing wastes from the tanks, and (4) methods for concrete removal. There were three major groups of deployment technologies: ``past practice`` technologies, mechanical arm-based technologies, and vehicle-based technologies. The different technologies were then combined into logical sequences of deployment platform, problem, end effector, conveyance, post-removal treatment required (if any), and disposition of the waste. Many waste removal options are available, but the best technology in one set of circumstances at one site might not be the best type to use at a different site. No single technology is capable of treating the entire spectrum of wastes that will be encountered in GAAT. None of the systems used in other industries appears to be suitable, primarily because of the nature of the sludges in the GAAT Operable Unit (OU), their radiation levels, and tank geometries. Other commercial technologies were investigated but rejected because the authors did not believe them to be applicable.

It has become a trend that worldwide enterprises and organizations apply new technologies to improve their operations; besides, it has higher cost and less flexibility to construct and manage traditional servers, therefore the current mainstream is to use server virtualization technology. However, from these new technology organizations will not necessarily get the expected benefits because each one has its own level of organizational complexity and abilities to accept changes. The researcher investigated key factors affecting the adoption of virtualization technology through two phases. In phase I, the researcher reviewed literature and then applied the dimensions of "Information Systems Success Model" (ISSM) to generalize the factors affecting the adoption of virtualization technology to be the preliminary theoretical framework and develop a questionnaire; in phase II, a three-round Delphi Method was used to integrate the opinions of experts from related fields which were then gradually converged in order to obtain a stable and objective questionnaire of key factors so that these results were expected to provide references for organizations' adoption of server virtualization technology and future studies.

To gain insights into how technological communication tools impact effective communication among clinicians, which is critical for patient safety. This multi-site observational study analyzes inter-clinician communication and interaction with information technology, with a focus on the critical process of patient transfer from the Emergency Department to General Internal Medicine. Mount Sinai Hospital, Sunnybrook Health Sciences Centre and Toronto General Hospital. At least five ED and general internal medicine nurses and physicians directly involved in patient transfers were observed on separate occasions at each institution. N/A. N/A. The study provides insight into clinician workflow, evaluates current hospital communication systems and identifies key issues affecting communication: interruptions, issues with numeric pagers, lack of integrated communication tools, lack of awareness of consultation status, inefficiencies related to the paper chart, unintuitive user interfaces, mixed use of electronic and paper systems and lack of up-to-date contact information. It also identifies design trade-offs to be negotiated: synchronous communication vs. reducing interruptions, notification of patient status vs. reducing interruptions and speed vs. quality of handovers. The issues listed should be considered in the design of new technology for hospital communications. © The Author 2015.

Full Text Available The purpose of this study is to identify the level of technology acceptance among school teachers from the components of awareness and motivation, training and courses, training design, and supports and facilities. This study also aims to investigate whether teachers’ acceptance of technology could influence their readiness for the pedagogical use of mobile phone technology if it is to be implemented in school. A quantitative questionnaire was administered to thirty eight teachers who teach Information and Technology (IT subject from different primary schools in Penang, Malaysia during a program on Teachers’ Development. Data revealed that the level of technology acceptance among respondents in terms of awareness and motivation, training and courses, training design and supports and facilities was generally high. Despite this positive acceptance of technology, teachers’ readiness for the use of mobile phone in teaching and learning was found to be at a considerably low level. However, the study identified a significant correlation between respondents’ awareness and motivation towards technology with their readiness for the pedagogical usage of mobile phone. It was also found that gender is a possible factor influencing the respondents’ readiness. As implication, this paper probes the influence of technology acceptance on teachers’ readiness for the pedagogical usage of mobile phone and the possible implications this influence affords.

Can CDM bring technology transfer to China?-An empirical study of technology transfer in China's CDM projects

International Nuclear Information System (INIS)

Wang Bo

2010-01-01

China has undertaken the greatest number of projects and reported the largest emission reductions on the global clean development mechanism (CDM) market. As technology transfer (TT) was designed to play a key role for Annex II countries in achieving greenhouse gas emission reductions, this study examines various factors that have affected CDM and TT in China. The proportion of total income derived from the certified emissions reductions (CER) plays a key role in the project owners' decision to adopt foreign technology. Incompatibility of CDM procedures with Chinese domestic procedures, technology diffusion (TD) effects, Chinese government policy and the role of carbon traders and CDM project consultants all contribute to the different degrees and forms of TT. International carbon traders and CDM consultants could play a larger role in TT in China's CDM projects as investors and brokers in the future.

Politicizing science: conceptions of politics in science and technology studies.

Science.gov (United States)

Brown, Mark B

2015-02-01

This essay examines five ideal-typical conceptions of politics in science and technology studies. Rather than evaluating these conceptions with reference to a single standard, the essay shows how different conceptions of politics serve distinct purposes: normative critique, two approaches to empirical description, and two views of democracy. I discuss each conception of politics with respect to how well it fulfills its apparent primary purpose, as well as its implications for the purpose of studying a key issue in contemporary democratic societies: the politicization of science. In this respect, the essay goes beyond classifying different conceptions of politics and also recommends the fifth conception as especially conducive to understanding and shaping the processes whereby science becomes a site or object of political activity. The essay also employs several analytical distinctions to help clarify the differences among conceptions of politics: between science as 'political' (adjective) and science as a site of 'politics' (noun), between spatial-conceptions and activity-conceptions of politics, between latent conflicts and actual conflicts, and between politics and power. The essay also makes the methodological argument that the politics of science and technology is best studied with concepts and methods that facilitate dialogue between actors and analysts. The main goal, however, is not to defend a particular view of politics, but to promote conversation on the conceptions of politics that animate research in social studies of science and technology.

Emerging environmental technologies and environmental technology policy

Science.gov (United States)

Clarke, Leon Edward

This dissertation explores the role and design of environmental technology policy when environmental innovation is embodied in emerging environmental technologies such as photovoltaic cells or fuel cells. The dissertation consists of three individual studies, all of which use a simplified, general model industry between an emerging environmental technology and an entrenched, more-polluting technology. It clarifies the situations in which environmental technology policy can achieve high welfare and those in which it cannot; and it separates the possible situations an emerging environmental technology might face into four scenarios, each with its own technology policy recommendations. The second study attempts to clarify which of two factors is having a larger limiting effect on private investment in photovoltaics: the failure to internalize the environmental costs of fossil fuel electricity generation or a broad set of innovation market failures that apply to innovation irrespective of environmental concerns. The study indicates that innovation market failures are probably having a significantly larger impact than incomplete internalization. The third study explores the effectiveness of adoption subsidies at encouraging private-sector innovation. The conclusion is that adoption subsidies probably have only a limited effect on long-term, private-sector research. Two important general conclusions of the dissertation are (1) that optimal technology policy should begin with technology-push measures and end with demand-pull measures; and (2) that the technological response to internalization instruments, such as emissions taxes, may be highly nonlinear.

Educators are integrating new technology into medical curriculum. The impact of newer technology on educational outcomes remains unclear. We aimed to determine if two pilot interventions, (1) introducing iPads into problem-based learning (PBL) sessions and (2) online tutoring would improve the educational experience of our learners. We voluntarily assigned 26 second-year medical students to iPad-based PBL sessions. Five students were assigned to Skype for exam remediation. We performed a mixed-method evaluation to determine efficacy. Pilot 1: Seventeen students completed a survey following their use of an iPad during the second-year PBL curriculum. Students noted the iPad allows for researching information in real time, annotating lecture notes, and viewing sharper images. Data indicate that iPads have value in medical education and are a positive addition to the curriculum. Pilot 2: Students agreed that online tutoring is at least or more effective than in-person tutoring. In our pilot studies, students experienced that iPads and Skype are beneficial in medical education and can be successfully employed in areas such as PBL and remediation. Educators should continue to further examine innovative opportunities for introducing technology into medical education. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

2003-01-01

A study was conducted to identify and evaluate noise reduction technologies for advanced ducted prop propulsion systems that would allow increased capacity operation and result in an economically competitive commercial transport. The study investigated the aero/acoustic/structural advancements in fan and nacelle technology required to match or exceed the fuel burned and economic benefits of a constrained diameter large Advanced Ducted Propeller (ADP) compared to an unconstrained ADP propulsion system with a noise goal of 5 to 10 EPNDB reduction relative to FAR 36 Stage 3 at each of the three measuring stations namely, takeoff (cutback), approach and sideline. A second generation ADP was selected to operate within the maximum nacelle diameter constrain of 160 deg to allow installation under the wing. The impact of fan and nacelle technologies of the second generation ADP on fuel burn and direct operating costs for a typical 3000 nm mission was evaluated through use of a large, twin engine commercial airplane simulation model. The major emphasis of this study focused on fan blade aero/acoustic and structural technology evaluations and advanced nacelle designs. Results of this study have identified the testing required to verify the interactive performance of these components, along with noise characteristics, by wind tunnel testing utilizing and advanced interaction rig.

The adoption of new medical technologies often generates losses in efficiency associated with the excess or insufficient acquisition of new equipment, an inappropriate choice (in terms of economic and clinical parameters) of medical equipment, and its poor use. Russia is a good example for exploring the problem of the ineffective adoption of new medical technologies due to the massive public investment in new equipment for medical institutions in 2006-2013. This study examines the procurement of new technologies in Russian hospitals to find the main causes of inefficiency. The research strategy was based on in-depth semistructured interviews with representatives of prominent actors (regional health care authorities, hospital executives, senior physicians). The main result is that inefficiencies arise from the contradiction between hospitals' and authorities' motivation for acquiring new technologies: hospitals tend to adopt technologies which bring benefits to their department heads and physicians and minimize maintenance and servicing costs, while the authorities' main concern is the initial cost of the technology.

This study examined the relations of preservice science teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences to their self-efficacy beliefs about technological pedagogical content knowledge (TPACK). The present study also investigated interrelations among preservice teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences. The participants of study were 665 elementary preservice science teachers (467 females, 198 males) from 7 colleges in Turkey. The proposed model based on educational technology literature was tested using structural equation modeling. The model testing results revealed that preservice teachers' technology competencies and experiences mediated the relation of technology ownership to their TPACK self efficacy beliefs. The direct relation of their possession of technology to their TPACK self efficacy beliefs was insignificant while the indirect relation through their technology competencies and experiences was significant. The results also indicated there were significant direct effects of preservice teachers' attitudes towards technology use, technology competencies, and experiences on their TPACK self efficacy beliefs.

ECLSS Integration Analysis: Advanced ECLSS Subsystem and Instrumentation Technology Study for the Space Exploration Initiative

Science.gov (United States)

1990-01-01

In his July 1989 space policy speech, President Bush proposed a long range continuing commitment to space exploration and development. Included in his goals were the establishment of permanent lunar and Mars habitats and the development of extended duration space transportation. In both cases, a major issue is the availability of qualified sensor technologies for use in real-time monitoring and control of integrated physical/chemical/biological (p/c/b) Environmental Control and Life Support Systems (ECLSS). The purpose of this study is to determine the most promising instrumentation technologies for future ECLSS applications. The study approach is as follows: 1. Precursor ECLSS Subsystem Technology Trade Study - A database of existing and advanced Atmosphere Revitalization (AR) and Water Recovery and Management (WRM) ECLSS subsystem technologies was created. A trade study was performed to recommend AR and WRM subsystem technologies for future lunar and Mars mission scenarios. The purpose of this trade study was to begin defining future ECLSS instrumentation requirements as a precursor to determining the instrumentation technologies that will be applicable to future ECLS systems. 2. Instrumentation Survey - An instrumentation database of Chemical, Microbial, Conductivity, Humidity, Flowrate, Pressure, and Temperature sensors was created. Each page of the sensor database report contains information for one type of sensor, including a description of the operating principles, specifications, and the reference(s) from which the information was obtained. This section includes a cursory look at the history of instrumentation on U.S. spacecraft. 3. Results and Recommendations - Instrumentation technologies were recommended for further research and optimization based on a consideration of both of the above sections. A sensor or monitor technology was recommended based on its applicability to future ECLS systems, as defined by the ECLSS Trade Study (1), and on whether its

The variable stream control engine, VSCE-502B, was selected as the base engine, with the inverted flow engine concept selected as a backup. Critical component technologies were identified, and technology programs were formulated. Several engine configurations were defined on a preliminary basis to serve as demonstration vehicles for the various technologies. The different configurations present compromises in cost, technical risk, and technology return. Plans for possible variably cycle engine technology programs were formulated by synthesizing the technology requirements with the different demonstrator configurations.

Managing knowledge: a technology transfer case study in IEN

International Nuclear Information System (INIS)

Pereira, Ana Gabriella Amorim Abreu

2009-01-01

Knowledge management is paramount nowadays. In order to enable the members of an organization to deal with their current situations effectively it is mandatory to know and enhance its intellectual capital. Managing the organization knowledge is important to the extent that it allows and reinforce its mission (what we are trying to accomplish?), and performance (how do we deliver the results?). As a result of a knowledge management effort, the organization can create value for itself and for society as a whole. In this paper, we argue that a technology developed at a research institute and transferred to an industry is knowledge to be managed in order to create value, both for the society and for the Institute. In order to manage such knowledge, it is proposed an approach to enhance the value creation potential of a technology transfer. This paper propose an investigation to expand the understanding on how a public research institute and a private firm could introduce their value creation wishes into a technology transfer agreement in a way to reflect and provide the realization of those wishes. It is proposed that, from the identification of the organizations expectations it is possible to infer which agreement attributes will contribute to that value creation and to establish satisfactory agreement configurations. These configurations have the potential to generate those consequences, given that, through the transfer, each organization seeks to increase potential benefits and to reduce potential sacrifices. Supported by exchange flow and value creation models, by the knowledge management and the means-end theory, an approach to increase the value creation potential of a technology transfer is proposed. Evidences from a case study sustain the proposed approach. The case study unity is the Instituto de Engenharia Nuclear, a public research institute. (author)

Halko, Sajanee; Kientz, Julie A.

Though a variety of persuasive health applications have been designed with a preventive standpoint toward diseases in mind, many have been designed largely for a general audience. Designers of these technologies may achieve more success if applications consider an individual's personality type. Our goal for this research was to explore the relationship between personality and persuasive technologies in the context of health-promoting mobile applications. We conducted an online survey with 240 participants using storyboards depicting eight different persuasive strategies, the Big Five Inventory for personality domains, and questions on perceptions of the persuasive technologies. Our results and analysis revealed a number of significant relationships between personality and the persuasive technologies we evaluated. The findings from this study can guide the development of persuasive technologies that can cater to individual personalities to improve the likelihood of their success.

Study on the knowledge management of strategic alliances in high technology enterprises

TANG Yu; WANG Hong-qi; WANG Shan-shan

2005-01-01

With the development of knowledge economy, the competition between high technology enterprises has gradually evolved into the competition of core competence based on knowledge, because high technology enterprises are typical knowledge-based enterprises. Few enterprises, especially for high technology firms, have all of the knowledge they need to compete effectively in the marketplace both at home and abroad, so more and more high technology companies are taking the advantage of strategic alliances to get their complementary knowledge. Since knowledge is the source of an enterprise' s competitiveness, knowledge management has become the most important means for enterprises to gain competitive advantage. There has been an increased growth in the literature on strategic alliances in recent decades. But what is less discussed in the existing literature on strategic alliances is the issue of knowledge management of strategic alliances in high technology enterprises. Based on the characteristics of strategic alliances in high technology enterprises, and in line with the implication and the goal of knowledge management, this study tries to delve into this issue. The paper analyzes the key factors relevant to the knowledge management of strategic alliances in high technology enterprises and proposes guide lines on the process and measures that should be taken in the knowledge management of strategic alliances in high technology enterprises.

It is essential for nursing students to be equipped with the necessary technology skills throughout and after their study period. Their acceptance of this technology depends largely on their attitudes towards technology. To explore the evolution in nursing students' attitudes towards technology, and to determine whether there was a change in participants' formal education in technology over their four years of study. A longitudinal panel study was conducted in a single school of nursing in Jordan. A total of 140 students were followed over their four years of undergraduate study. They completed the same tool (the Technology Attitude Scale) each year, to capture any changes in their attitudes towards technology across the years. In all four waves of data collection, students showed positive attitudes towards technology, with the highest attitude scores being in their final year (M=6.19, SD=0.72). As the students spent more time on their nursing education, they were found to have a more positive attitude. Thus, a strong positive relationship existed between this formal education in technology and attitudes: as the students' education in technology increased, their attitudes were more positive. A remarkable development in students' attitudes towards technology is reported in this study. The positive attitudes displayed by the students should be enhanced by providing technology-related subjects during their studies in nursing schools at a very early stage.

Directory of Open Access Journals (Sweden)

Xinbao Yu

2010-01-01

Full Text Available This paper describes a comparison study on three different technologies (i.e., thermocouple, electrical resistivity probe and Time Domain Reflectometry (TDR that are commonly used for frost measurement. Specially, the paper developed an analyses procedure to estimate the freezing-thawing status based on the dielectric properties of freezing soil. Experiments were conducted where the data of temperature, electrical resistivity, and dielectric constant were simultaneously monitored during the freezing/thawing process. The comparison uncovered the advantages and limitations of these technologies for frost measurement. The experimental results indicated that TDR measured soil dielectric constant clearly indicates the different stages of the freezing/thawing process. Analyses method was developed to determine not only the onset of freezing or thawing, but also the extent of their development. This is a major advantage of TDR over other technologies.

Green technology is the development and application of products, equipment and systems used to conserve the environment which minimizes the negative impact from human activities. The technology can be in the form of green buildings or renewable energy such as hydro, solar and biogas. Development in SDC is still at the early stage, hence there is a prospect to plan for proper green concept implementation. With the increasing number of construction projects particularly in the rapid developing city of Kota Kinabalu, green technology as a whole is becoming more significant as it helps to develop effective solutions to encounter global environmental issues. Although there has been lengthy discussion on the green technology, the visibility of the implementation is still yet to be seen widely in Kota Kinabalu. The implementation of green technology in construction will support dynamic growth of economic development activities, while improving the environment. Hence, it is important to develop a strategic plan to promote the use of green technology while the areas are still developing. The focus of this correlative-based approach study is to investigate the perception and implementation of green technology in Kota Kinabalu from the industrial perspectives.

Explaining experience curves for new energy technologies. A case study of liquefied natural gas

International Nuclear Information System (INIS)

Greaker, Mads; Lund Sagen, Eirik

2008-01-01

Many new energy technologies seem to experience a fall in unit price as they mature. In this paper we study the unit price of liquefying natural gas in order to make it transportable by ship to gas power installations all over the world. Our point of departure is the experience curve approach, however unlike many other studies of new energy technologies, we also seek to account for autonomous technological change, scale effects and the effects of upstream competition among technology suppliers. To our surprise we find that upstream competition is by far the most important factor contributing to the fall in unit price. With respect to the natural gas business, this may have implications for the future development in prices as the effect of increased upstream competition is temporary and likely to weaken a lot sooner than effects from learning and technological change. Another more general policy implication, is that while promoting new energy technologies, governments must not forget to pay attention to competition policy. (author)

2016-02-01

Fibromyalgia management remains complicated and challenging. Health information technology is an evidence-based, nonpharmacological self and symptom management strategy, but few studies have evaluated its feasibility for managing fibromyalgia patients in clinical practice. FibroGuide is an example of an evidence-based, interactive, and computer-based program comprised of 10 educational modules on fibromyalgia. Study aims were to: (1) develop a process for implementing FibroGuide into the routine care of patients with fibromyalgia, (2) evaluate the overall impact on fibromyalgia before and after a 12-week implementation, and (3) assess patient perspectives on using FibroGuide health information technology to assist in self-management. In this pilot study, 35 participants with fibromyalgia were recruited from an Advanced Practice Registered Nurse's outpatient clinic. Using a descriptive design, quantitative data analysis was employed to address study aims. Based on data collection pre- and post-intervention using paired samples testing, a statistically significant change (p = .017) was observed in overall fibromyalgia impact (improved symptom severity, activity, and function). Majority felt that FibroGuide was helpful as part of their routine care, and nearly half reported that it assisted in their self-management. Although 65% noted that technology was an effective and efficient way to receive education for fibromyalgia management, 57% preferred talking to healthcare providers. Larger longitudinal studies are needed on the use of health information technology in fibromyalgia, evaluating both statistical and clinical significance, while decreasing barriers to participant use for this promising adjunct to clinical management. Providers need to be well educated on supporting self-management strategies and health information technology. Copyright © 2016 American Society for Pain Management Nursing.

2011-01-01

We report the recent progress in our studies of cell biology using micro-/nano-technology. Cells have a size of several to tens of microns, which makes them easily manipulated by micro-/nano-technology. The shape of the cell influences the alignment of the actin cytoskeleton, which bears the main forces of the cell, maintains the shape,and mediates a series of biochemical reactions. We invented a stretching device and studied the real-time actin filament dynamics under stretch. We found that one stretch cycle shortened the actin filaments and promoted their reassemble process. Cell migration is a complex mechanical process. We found that cell geometry determines the cell polarity and migration direction. We fabricated three-dimensional surfaces to mimic the topography in vivo, and further built a cell culture model by integrating the three-dimensional surface, microfluidics, cell patterning,and coculturing of multiple cell types. We also investigated the neuronal guidance by surface patterning. (authors)

2016-07-01

Nursing education is challenged to prepare students for complex healthcare needs through the integration of teamwork and informatics. Technology has become an important teaching tool in the blended classroom to enhance group based learning experiences. Faculty evaluation of classroom technologies is imperative prior to adoption. Few studies have directly compared various technologies and their impact on student satisfaction and learning. The purpose of this study was to evaluate technology enhanced teaching methods on the learning and satisfaction of graduate students in an advanced pharmacology class using an unfolding case study. After IRB approval, students were randomly assigned to one of three groups: blogging group, wiki group or webinar group. Students completed the evolving case study using the assigned interactive technology. Student names were removed from the case studies. Faculty evaluated the case study using a rubric, while blinded to the assigned technology method used. No significant difference was found on case study grades, the range of grades on the assignment demonstrated little differences between the methods used. Students indicated an overall positive impact related to networking and collaboration on a satisfaction survey. Impact of technology methods needs to be explored in other areas of graduate nursing education. Copyright © 2016 Elsevier Ltd. All rights reserved.

2014-12-01

Full Text Available Polytechnic instruction has a common place in the Cuban education system (Gasperini, 2000. In polytechnic institutions, teachers leverage technological tools to prepare students for labor market competences. This case study examined a polytechnic institution in Cuba to consider how teachers defined educational technology. Based on teacher questionnaire responses, site-based teacher interviews, and field observations, technology was primarily viewed as a method for student preparation. In other words, teachers used technology to prepare students for their future careers and the technology they will need to be successful in that career. The study found that teachers highly valued their technical pedagogical training, believed that the growing spaces were an integral part of their technology based instruction, and claimed that the limited resources was their greatest barrier to integrating ICT in the classroom.

Jesso, A. T.; Kondratieva, M. F.

2016-02-01

In this study, instructors of undergraduate mathematics from post-secondary institutions in Newfoundland were surveyed (N = 13) and interviewed (N = 8) about their use of, experiences with, and views on, technologically assisted teaching. It was found that the majority of them regularly use technologies for organizational and communication purposes. However, the use of math-specific technology such as computer algebra systems, or dynamic geometry software for instructional, exploratory, and creative activities with students takes place mostly on an individual basis, only occasionally, and is very much topic specific. This was even the case for those instructors who use technology proficiently in their research. The data also suggested that familiarity with and discussions of examples of technology implementation in teaching at regular and field-oriented professional development seminars within mathematics departments could potentially increase the use of math-specific technology by instructors.

2017-09-01

Recently, mobile health technology has emerged as a promising avenue for improving physician-patient communication and patient outcomes. The objective of our study was to determine the public's perception of barriers and benefits to using mobile health technology technologies to enhance recovery after operation. We used the Empire State Poll to ask 2 open-ended questions to 800 participants assessing their perceptions of benefits and barriers to use mobile health technology after operation. All responses were coded independently, and any discrepancies were resolved by consensus. We used grounded theory to allow themes to arise from the codes. Interrater reliability was calculated using Cohen's Kappa. Participants identified a range of possible barriers to using mobile health technology apps after operation including: protecting personal health information, technology effectiveness and failure, preference for face-to-face interaction with their surgeon, level of effort required, and ability of the older adults to navigate mobile health technology. Participants identified multiple possible benefits including: better monitoring, improved communication with their surgeon, minimizing follow-up visits, improved convenience, and increased patient knowledge. In the study, 15% of all respondents stated there were no barriers whereas 6% stated there were no benefits. Participants were receptive to the many potential benefits of this technology to enhance not only their relationships with providers and the convenience of access, but also their health outcomes. We must address participants concerns about data security and their fears of losing a personal relationship with their doctor. Copyright © 2017 Elsevier Inc. All rights reserved.

2018-01-01

Full Text Available Today, information technologies (IT are used in almost every production industry. While the aspects of IT are well studied and discussed in relevant monographs, articles, web sources, etc., this paper reviews the performance improvement options in the construction industry by leveraging IT. From a wide range of information technologies the author has picked the most relevant solutions, from his point of view, based on several considerations, the most important one being the lack of adequate attention to these technologies specifically in the construction industry. The paper covers the following technologies: Big Data (a smart technology for high-speed processing of huge and diverse data arrays; situation centers (SC for construction and operations projects (SCs are successfully used in other industries for operating control of sophisticated facilities; data warehouses (DW for the construction industry (DWs are viewed as a standalone project rather than a supplement to Data Mining or Big Data; operational and dispatch radio communication service (radio communication can ensure instant connectivity between several subscribers; VSAT (a satellite technology for prompt connection of a distant construction site with the 'outer world' when no alternatives are available. The paper briefly presents the essence of each technology, describes the pre-requisites for its use in construction, outlines the key advantages, limits and shortcomings, and lists construction projects where it shall be worthwhile to use a specific technology projects.

Estep, Judith

researcher and recipient relationship, specific to technology transfer. In this research, the evaluation criteria of several research organizations were assessed to understand the extent to which the success attributes that were identified in literature were considered when reviewing research proposals. While some of the organizations included a few of the success attributes, none of the organizations considered all of the attributes. In addition, none of the organizations quantified the value of the success attributes. The effectiveness of the model relies extensively on expert judgments to complete the model validation and quantification. Subject matter experts ranging from senior executives with extensive experience in technology transfer to principal research investigators from national labs, universities, utilities, and non-profit research organizations were used to ensure a comprehensive and cross-functional validation and quantification of the decision model. The quantified model was validated using a case study involving demand response (DR) technology proposals in the Pacific Northwest. The DR technologies were selected based on their potential to solve some of the region's most prevalent issues. In addition, several sensitivity scenarios were developed to test the model's response to extreme case scenarios, impact of perturbations in expert responses, and if it can be applied to other than demand response technologies. In other words, is the model technology agnostic? In addition, the flexibility of the model to be used as a tool for communicating which success attributes in a research proposal are deficient and need strengthening and how improvements would increase the overall technology transfer score were assessed. The low scoring success attributes in the case study proposals (e.g. project meetings, etc.) were clearly identified as the areas to be improved for increasing the technology transfer score. As a communication tool, the model could help a research

Nuclear technology and chronic diseases: an exploratory study evolving the clinical physician perception

International Nuclear Information System (INIS)

Sato, Renato Cesar

2010-01-01

This research is an exploratory cross-sectional study about the relationship of chronic disease and the use of nuclear technology. There is a concern over the increase of the prevalence of chronic disease in developing countries and it should hence be carefully evaluated in the context of societies, organizations and individuals. The technological advances experienced in the last decades especially in the nuclear technology area have created expectations to deal more efficiently with the challenge of chronic diseases. However little has been explored in this area under the point-of-view of medical doctors as agents who make this system of relations between disease and technology. The necessity for public and private planning to deal with this set of problems can benefit through an initial evaluation about the forthcoming theme, but should incorporate the agenda of health and technology planning for the following years. Using mixed methodology, made up of qualitative and quantitative approach, this research sought to reveal and configure important dimensions around the theme of this study. The field research was made up of interviews analyzed using techniques of fundamental theory and also of questionnaires sent by web analyzed statistically using exploratory factor analysis. These ventures allowed dimensions to be revealed that make up the perception of chronic disease and the use of nuclear technology. These dimensions presented in a form of a theoretical construct that were then discussed under the point of view of social theory and technological innovation. (author)

Read, Sheona A K; Kass, Gary S; Sutcliffe, Hilary R; Hankin, Steven M

2016-05-01

Technology-led innovation represents an important driver of European economic and industrial competitiveness and offers solutions to societal challenges. In order to facilitate responsible innovation and public acceptance, a need exists to identify and implement oversight approaches focused on the effective risk governance of emerging technologies. This article describes a foresight study on the governance of new technologies, using nanotechnology as a case example. Following a mapping of the governance landscape, four plausible foresight scenarios were developed, capturing critical uncertainties for nanotechnology governance. Key governance elements were then stress tested within these scenarios to see how well they might perform in a range of possible futures and to inform identification of the strengths, weaknesses, opportunities, and threats for nanotechnology governance in Europe. Based on the study outcomes, recommendations are proposed regarding the development of governance associated with the responsible development of new technologies. © 2015 Society for Risk Analysis.

Reliability studies in a developing technology

International Nuclear Information System (INIS)

Mitchell, L.A.; Osgood, C.; Radcliffe, S.J.

1975-01-01

The standard methods of reliability analysis can only be applied if valid failure statistics are available. In a developing technology the statistics which have been accumulated, over many years of conventional experience, are often rendered useless by environmental effects. Thus new data, which take account of the new environment, are required. This paper discusses the problem of optimizing the acquisition of these data when time-scales and resources are limited. It is concluded that the most fruitful strategy in assessing the reliability of mechanisms is to study the failures of individual joints whilst developing, where necessary, analytical tools to facilitate the use of these data. The approach is illustrated by examples from the field of tribology. Failures of rolling element bearings in moist, high-pressure carbon dioxide illustrate the important effects of apparently minor changes in the environment. New analytical techniques are developed from a study of friction failures in sliding joints. (author)

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

Informing international UNFCCC technology mechanisms from the ground up: Using biogas technology in South Africa as a case study to evaluate the usefulness of potential elements of an international technology agreement in the UNFCCC negotiations process

International Nuclear Information System (INIS)

Boyd, Anya

2012-01-01

Transfer of low carbon technologies to developing countries is 1 approach for tackling rising global emissions. An international technology transfer mechanism has been proposed under the UNFCCC; however, it remains unclear how this international mechanism would translate into local level technology implementation. This study uses biogas technology in South Africa to obtain empirical data inductively related to technology transfer. Observations and activities specific to the biogas sector in South Africa are put forward based on site visits and stakeholder discussions in South Africa, the UK, Germany and Sweden. This paper presents empirical findings on technology transfer in the biogas sector in South Africa and analyses the role of an international technology mechanism in supporting the uptake of biogas. Many of the barriers to biogas technology in South Africa are national level constraints such as lack of supportive policy environment, financial incentives and information sharing. This case study supports the argument that it will be unrealistic for international technology mechanisms to capture the necessary specificities of individual technologies at a country level. Therefore, as demonstrated through the example of biogas technology in South Africa, there is a need for both effective national and international engagement to support technology implementation. - Highlights: ► The UNFCCC technology mechanism aims to increase low carbon technology deployment. ► The interface of global technology frameworks and national implementation is unclear. ► Biogas is a widely used technology yet its uptake in South Africa (SA) is minimal. ► Empirical data is gathered from biogas sites in SA, UK, Germany and Sweden. ► Findings show biogas uptake in SA requires national and international support

Study for improvement of light water reactor technology, (3)

1991-01-01

The Japan Atomic Power Company has performed some studies, which are referred to as 'some feasibility studies of LWR technology', in order to help improve and up-grade the light water reactor technology. We would like to show the key results of the above studies in an orderly fashion in this document. As the third issue, this paper describes the study of the feasibility of applying a suppression pool system in a 4-loop PWR plant in order to reduce containment volume and evaluates the merits of such a system. The results confirmed the feasibility of such a plant consisting of a 4-loop plant with a suppression pool system. The expected merits of a suppression pool type PWR are as follows: (1) The volume within the containment boundary is half of that for the conventional plant. This reduces the material quantity substantially. (2) A wider layout space is obtained since the operating floor is located outside the containment are. And this improves the maneuverability of plant outage. (3) Low center of gravity of the plant contributes to improving the ability to withstand seismic activity. Although there are some open items left that should be confirmed, we consider that PWR with small CV is an appealing plant in the light of further sales points such as relaxing siting conditions, extending the use of robotics and so on.

Full Text Available The technological features of core concreting were analyzed as the main factor in ensuring of strength and reliability of compressed concrete-filled steel tubular (CFST members. We have conducted the analysis of existing concreting methods of CFST members. In this respect, the most dangerous types of possible technological defects of concrete core of CFST members are inhomogeneity along the height, voids, caverns, and concrete “weak spots”. The authors considered the influence of such technological factors of concreting: placeability, time, concrete mixture compaction method, concreting height on the concrete core strength of CFST members. Based on the experimental studies conducted we suggested the regression correlations for determining the concrete strength of CFST members of different length depending on the movability of concrete mixture and a time for its compaction. The authors performed the correlation analysis of technological factors of concreting on the strength of the concrete core. We carried out the comparison of data on the concrete core strength of CFST members, that were determined by non-destructive methods (sclerometer test results, ultrasonic method and direct compression strength tests. We experimentally proved that using movable mixtures with the slump of about 4 – 9 cm the overall variation coefficient of concrete core strength of CFST members along the height reaches nearly 13%. Based on the experimental studies conducted we suggested the guidelines on optimal regimes of concrete compaction during manufacturing CFST members at a construction site environment.

2016-02-03

To identify the impact the use of wearable technology could have in patients with osteoarthritis in terms of communication with healthcare providers and patients' empowerment to manage their condition. Qualitative study using focus groups with patients with osteoarthritis; data from patients' responses were analysed using Framework Methodology. 21 patients with knee osteoarthritis from the London area (age range 45-65 years) participated in a total of four focus groups. Recruitment continued until data saturation. The study was conducted in a university setting. Patients' responses suggested a positive attitude on the impact wearable technology could have on the management of osteoarthritis. It was perceived that the use of wearable devices would benefit patients in terms of feeling in control of their condition, providing them with awareness of their progress, empowering in terms of self-management and improving communication with their clinician. This paper suggests positive patient perspectives on the perceived benefits wearable technology could have on the management of osteoarthritis. The data that could be collected with the use of wearable technology could be beneficial both to patients and clinicians. The information obtained from this study suggests that introducing wearable technology into patient-centred care could enhance patient experience in the field of osteoarthritis and beyond.

Technology management: case study of an integrated health system.

Science.gov (United States)

Dahl, D H; McFarlan, T K

1994-12-01

Technology management has assumed a role of vital importance in today's health care environment. Capital reserves and operating income have been stretched by pervasive and expensive technologies, while overall reimbursement has been reduced. It is imperative for hospitals to develop and consistently use technology management processes that begin prior to a technology's introduction in the hospital and continue throughout its life cycle. At Samaritan Health System (SHS), an integrated health care delivery system based in Phoenix, technology management provides tools to improve decision making and assist in the system's integration strategy as well as control expenses. SHS uses a systemwide technology-specific plan to guide acquisition and/or funding decisions. This plan describes how particular technologies can help achieve SHS' organizational goals such as promoting system integration and/or improving patient outcomes while providing good economic value. After technologies are targeted in this systemwide plan they are prioritized using a two-stage capital prioritization process. The first stage of the capital prioritization process considers the quantitative and qualitative factors critical for equitable capital distribution across the system. The second stage develops a sense of ownership among the parties that affect and are affected by the allocation at a facility level. This process promotes an efficient, effective, equitable, and defensible approach to resource allocation and technology decision making. Minimizing equipment maintenance expenditures is also an integral part of technology management at SHS. The keys to reducing maintenance expenditures are having a process in place that supports a routine fiscal evaluation of maintenance coverage options and ensuring that manufacturers are obligated to provide critical maintenance resources at the time of equipment purchase. Maintenance service options under consideration in this report include full

2018-01-01

Background Technology-based health care has been promoted as an effective tool to enable clinicians to work smarter. However, some health stakeholders believe technology will compel users to work harder by creating extra work. Objective The objective of this study was to investigate how and why electronic health (eHealth) has been applied in Taiwan and to suggest implications that may inspire other countries facing similar challenges. Methods A qualitative methodology was adopted to obtain insightful inputs from deeper probing. Taiwan was selected as a typical case study, given its aging population, advanced technology, and comprehensive health care system. This study investigated 38 stakeholders in the health care ecosystem through in-depth interviews and focus groups, which provides an open, flexible, and enlightening way to study complex, dynamic, and interactive situations through informal conversation or a more structured, directed discussion. Results First, respondents indicated that the use of technology can enable seamless patient care and clinical benefits such as flexibility in time management. Second, the results suggested that a leader’s vision, authority, and management skills might influence success in health care innovation. Finally, the results implied that both internal and external organizational governance are highly relevant for implementing technology-based innovation in health care. Conclusions This study provided Taiwanese perspectives on how to intelligently use technology to benefit health care and debated the perception that technology prevents human interaction between clinicians and patients.

Holding a candle to innovation in concentrating solar power technologies: A study drawing on patent data

International Nuclear Information System (INIS)

Braun, Frauke G.; Hooper, Elizabeth; Wand, Robert; Zloczysti, Petra

2011-01-01

Improved understanding of the innovative pathways of renewable energy technologies is vital if we are to make the transition to a low carbon economy. This study presents new evidence on innovation and industry dynamics in concentrating solar power (CSP) technologies. Though CSP is undergoing a renaissance, existing innovation studies have explored innovative activity in solar technologies in general, ignoring the major differences between solar photovoltaic and CSP technologies. This study, based on patent data, examines the level and dynamics of innovative activity in CSP between 1978 and 2004. Our unique contribution, based on engineering expertise and detailed datawork, is a classification system mapping CSP technologies to the International Patent Classification (IPC) system. The innovation performance of CSP is found to be surprisingly weak compared to the patent boom in other green technologies. Performance was strong around 1980 before falling dramatically, and has only recently begun to show signs of recovery. Innovation and R and D are concentrated in high-tech countries; the US, Germany and Japan, which do not necessarily have high domestic CSP potential. Large CSP potential is, therefore, not a sufficient condition for innovation. Innovators must possess economic and scientific capabilities. - Research highlights: → We develop a new classification system which allows us to map innovation in CSP technologies to the International Patent Classification System. → Evidence of innovation patterns in concentrating solar power technologies is presented. → Innovation performance in CSP is surprisingly weak compared to patenting in other green technologies, despite its strong potential as a low carbon power generation technology.

Promoting community socio-ecological sustainability through technology: A case study from Chile

Science.gov (United States)

Aguayo, Claudio; Eames, Chris

2017-12-01

The importance of community learning in effecting social change towards ecological sustainability has been recognised for some time. More recently, the use of Information and Communication Technology (ICT) tools to promote socio-ecological sustainability has been shown to have potential in community education for sustainable development (ESD). The effective design and use of technology for community learning implies an understanding of a range of cross-dimensional factors including: socio-cultural characteristics and needs of the target audience; considerations of available and culturally responsive types of technology; and non-formal pedagogical ESD strategies for community empowerment. In addition, both technology itself and social communities are dynamically evolving and complex entities. This article presents a case study which evaluated the potential of ICT for promoting ecological literacy and action competence amongst community members in southern Chile. The case study addressed the ecological deterioration of a lake, which is having deep social, economic, recreational and cultural implications locally. The authors' research involved developing a theoretical framework for the design, implementation and use of ICT for community learning for sustainability. The framework was based on key ideas from ESD, ICT and community education, and was underpinned by a systems thinking approach to account for the dynamism and complexity of such settings. Activity theory provided a frame to address overarching socio-cultural elements when using technology as a mediating tool for community learning. The authors' findings suggest that the use of an ICT tool, such as a website, can enhance ecological literacy in relation to a local socio-ecological issue.

Morris, Neil P; Ramsay, Luke; Chauhan, Vikesh

2012-06-01

This article reports findings from a study investigating undergraduate biological sciences students' use of technology and computer devices for learning and the effect of providing students with a tablet device. A controlled study was conducted to collect quantitative and qualitative data on the impact of a tablet device on students' use of devices and technology for learning. Overall, we found that students made extensive use of the tablet device for learning, using it in preference to laptop computers to retrieve information, record lectures, and access learning resources. In line with other studies, we found that undergraduate students only use familiar Web 2.0 technologies and that the tablet device did not alter this behavior for the majority of tools. We conclude that undergraduate science students can make extensive use of a tablet device to enhance their learning opportunities without institutions changing their teaching methods or computer systems, but that institutional intervention may be needed to drive changes in student behavior toward the use of novel Web 2.0 technologies.

The objective of this study was to investigate how and why electronic health (eHealth) has been applied in Taiwan and to suggest implications that may inspire other countries facing similar challenges. A qualitative methodology was adopted to obtain insightful inputs from deeper probing. Taiwan was selected as a typical case study, given its aging population, advanced technology, and comprehensive health care system. This study investigated 38 stakeholders in the health care ecosystem through in-depth interviews and focus groups, which provides an open, flexible, and enlightening way to study complex, dynamic, and interactive situations through informal conversation or a more structured, directed discussion. First, respondents indicated that the use of technology can enable seamless patient care and clinical benefits such as flexibility in time management. Second, the results suggested that a leader's vision, authority, and management skills might influence success in health care innovation. Finally, the results implied that both internal and external organizational governance are highly relevant for implementing technology-based innovation in health care. This study provided Taiwanese perspectives on how to intelligently use technology to benefit health care and debated the perception that technology prevents human interaction between clinicians and patients. ©Sonia Chien-I Chen.

Full Text Available For many years, business has invested significant resources in information technology, hardware, software, and manpower. The Productivity Paradox is the seeming lack of productivity gains despite the increased investment in IT. For many years the existence of a Productivity Paradox has been the subject of research interest. Conflicting results have been obtained from a variety of data sets. Until this time however there has been no study that has investigated European companies’ use of information technology and its impact on productivity. The objective of this study was to investigate information technology productivity with a new data set from a European published source, and measuring productivity using both market and financial based measures. Results of the study indicated that information technology did have a consistent positive impact on firm level productivity in Europe for the years 1996, 1997, and 1998. Both market and financial based productivity measures provided consistent positive significant returns with regard to IT productivity. The major contribution of the study is that it provides an analysis of the impact of European information technology on firm and economic productivity.

Hackers against technology: Critique and recuperation in technological cycles.

Maxigas

2017-12-01

I offer an interpretation of hackers' technological choices through a theoretical framework of critique and recuperation in technological cycles, building on prior research that brings the pragmatic sociology of Boltanski and Chiapello to bear on matters in Science and Technology Studies. I argue that contextualizing technology choices in the development of capitalism through innovation illuminates their political significance. I start with the counterintuitive observation that some browser extensions popular with hackers, like RequestPolicy, make it considerably harder for them to look at websites. This observation showcases the Luddite aspects of hackerdom, in that they are willing to 'break' popular websites that would otherwise cheat on the user. In line with an undercurrent of hacker studies, in this case study I find hackers fighting technological progress they see as social decline.

2004-01-01

Full Text Available Research has increasingly uncovered the cognitive, cultural, and economic advantages of bilingualism and the positive impact of heritage language on children's second language acquisition (M:cLaughlin, 1995. As one type of heritage language education organizations, Chinese language schools have been in existence for decades in the U.S., but their practices have remained informal and not readily accessible to people from other cultures. In order to bridge this gap, this ethnographic study illustrates family and community involvement in promoting language proficiency in heritage language populations and explores language education methods practiced in Chinese community language schools in an urban Southern California area. The study examines the intricate issues affecting heritage language learning and explores the potential uses of technology in assisting young learners in acquiring their heritage language (Chinese. In addition, the study generates guidelines for adapting existing technology-assisted language programs (e.g., the Chinese Cultural Crystals for instructional uses.

Science.gov (United States)

Howlett, R. A.

1975-01-01

A continuation of the NASA/P and WA study to evaluate various types of propulsion systems for advanced commercial supersonic transports has resulted in the identification of two very promising engine concepts. They are the Variable Stream Control Engine which provides independent temperature and velocity control for two coannular exhaust streams, and a derivative of this engine, a Variable Cycle Engine that employs a rear flow-inverter valve to vary the bypass ratio of the cycle. Both concepts are based on advanced engine technology and have the potential for significant improvements in jet noise, exhaust emissions and economic characteristics relative to current technology supersonic engines. Extensive research and technology programs are required in several critical areas that are unique to these supersonic Variable Cycle Engines to realize these potential improvements. Parametric cycle and integration studies of conventional and Variable Cycle Engines are reviewed, features of the two most promising engine concepts are described, and critical technology requirements and required programs are summarized.

2016-01-01

Full Text Available Modern information and communication technologies together with intelligent devices provide a continuous inflow of large amounts of data that are used by traffic and transport systems. Collecting traffic data does not represent a challenge nowadays, but the issues remains in relation to storing and processing increasing amounts of data. In this paper we have investigated the possibilities of using Big Data technology to store and process data in the transport domain. The term Big Data refers to a large volume of information resource, its velocity and variety, far beyond the capabilities of commonly used software for storing, processing and data management. In our case study, Apache™ Hadoop® Big Data was used for processing data collected from 10 automatic traffic counters set up in Novi Sad and its surroundings. Indicators of traffic load which were calculated using the Big Data platforms were presented using tables and graphs in Microsoft Office Excel tool. The visualization and geolocation of the obtained indicators were performed using the Microsoft Business Intelligence (BI tools such as: Excel Power View and Excel Power Map. This case study showed that Big Data technologies combined with the BI tools can be used as a reliable support in monitoring of the traffic management systems.

Enhancing international technology cooperation for climate change mitigation. Lessons from an electromobility case study

Energy Technology Data Exchange (ETDEWEB)

Bhasin, Shikha

2014-07-01

As a global agreement on climate mitigation and absolute emissions reductions remains grid-locked, this paper assesses whether the prospects for international technology cooperation in low-carbon sectors can be improved. It analyses the case of international cooperation on electric vehicle technologies to elaborate on the trade-offs that cooperation such as this inherently attempts to balance- national growth objectives of industrial and technology development versus the global goods benefit of reducing greenhouse gas (GHG) emissions. It focuses on bilateral German-Chinese programmes for electric vehicle development, as well as multilateral platforms on low-carbon technology cooperation related to electric vehicles. Based on insights from these cases studies, this paper ultimately provides policy recommendations to address gaps in international technology cooperation at a bilateral level for ongoing German-Chinese engagement on electric vehicles; and at a multilateral level with a focus on the emerging technology cooperation framework of the United Nations Framework Convention on Climate Change (UNFCCC).

Modern Wildlife Monitoring Technologies: Conservationists versus Communities? A Case Study: The Terai-Arc Landscape, Nepal

Directory of Open Access Journals (Sweden)

Yashaswi Shrestha

2018-01-01

Full Text Available The use of new and advanced wildlife monitoring technologies is shifting the paradigm of wildlife conservation and management. These digital technologies are helping wildlife conservationists and researchers around the world to monitor and manage wildlife with more precision and efficiency. However, this research study highlights some of the key drawbacks of using such modern technologies for wildlife conservation and management especially in developing countries, where the digital divide often clearly separates well-endowed conservation organisations and rural communities. It provides an insight into how the extensive use of such digital wildlife monitoring technologies can often marginalise the role of local and indigenous communities in wildlife management. Our case study, which was conducted in the Terai Arc Landscape (TAL in southern Nepal, includes interviews with several wildlife experts, biologists, and members of local and indigenous communities. Findings indicate that the increasing militarisation and centralisation of protected area management, and the lack of universal access to the information gathered using modern monitoring technologies, have notably led to the marginalisation of local and indigenous communities in the region. These developments not only undermine the benefits of using such technologies but have also caused a rift between conservation organisations and local communities. As a result, this research study recommends that conservation organisations who advocate for the use of such technologies need to hold consultations and dialogues between conservationists and local and indigenous community members in order to be more inclusive and allow for a cross cultural and an interdisciplinary understanding of the best practices for the conservation and management of wildlife.

Black, B. M.; Magliozzi, B.; Rohrbach, C.

1983-01-01

A study to define potential benefits of advanced technology propeller for 1985-1990 STAT commuter airplanes was completed. Two baselines, a Convair, 30 passenger, 0.47 Mach number airplane and a Lockheed, 50 passenger, 0.70 Mach number airplane, were selected from NASA-Ames sponsored airframe contracts. Parametric performance, noise level, weight and cost trends for propellers with varying number of blades, activity factor, camber and diameter incorporating blade sweep, tip proplets, advanced composite materials, advanced airfoils, advanced prevision synchrophasing and counter-rotation are presented. The resulting DOC, fuel burned, empty weight and acquisition cost benefits are presented for resizings of the two baseline airplanes. Six-bladed propeller having advanced composite blades, advanced airfoils, tip proplets and advanced prevision synchrophasers provided the maximum DOC improvements for both airplanes. DOC and fuel burned were reduced by 8.3% and 17.0% respectively for the Convair airplane and by 24.9% and 41.2% respectively for the Lockheed airplane. The larger reductions arose from a baseline definition with very heavy fuselage acoustic treatment. An alternate baseline, with a cabin noise 13dB in excess of the objective, was also studied.

2017-06-23

Information and communication technologies (ICTs) are increasingly recognized as having an important role in the delivery of mental health services for youth. Recent studies have evaluated young people's access and use of technology, as well as their perspectives on using technology to receive mental health information, services, and support; however, limited attention has been given to the perspectives of family members in this regard. The aim of this study was to explore the perspectives of family members on the use of ICTs to deliver mental health services to youth within the context of specialized early intervention for a first-episode psychosis (FEP). Six focus groups were conducted with family members recruited from an early intervention program for psychosis. Twelve family members participated in the study (target sample was 12-18, and recruitment efforts took place over the duration of 1 year). A 12-item semistructured focus group guide was developed to explore past experiences of technology and recommendations for the use of technology in youth mental health service delivery. A qualitative thematic analysis guided the identification and organization of common themes and patterns identified across the dataset. Findings were organized by the following themes: access and use of technology, potential negative impacts of technology on youth in recovery, potential benefits of using technology to deliver mental health services to youth, and recommendations to use technology for (1) providing quality information in a manner that is accessible to individuals of diverse socioeconomic backgrounds, (2) facilitating communication with health care professionals and services, and (3) increasing access to peer support. To our knowledge, this is among the first (or the first) to explore the perspectives of family members of youth being treated for FEP on the use of technology for mental health care. Our results highlight the importance of considering diverse experiences

Cogeneration Technology Alternatives Study (CTAS). Volume 3: Energy conversion system characteristics

Science.gov (United States)

1980-01-01

Six current and thirty-six advanced energy conversion systems were defined and combined with appropriate balance of plant equipment. Twenty-six industrial processes were selected from among the high energy consuming industries to serve as a frame work for the study. Each conversion system was analyzed as a cogenerator with each industrial plant. Fuel consumption, costs, and environmental intrusion were evaluated and compared to corresponding traditional values. The advanced energy conversion technologies indicated reduced fuel consumption, costs, and emissions. Fuel energy savings of 10 to 25 percent were predicted compared to traditional on site furnaces and utility electricity. With the variety of industrial requirements, each advanced technology had attractive applications. Fuel cells indicated the greatest fuel energy savings and emission reductions. Gas turbines and combined cycles indicated high overall annual savings. Steam turbines and gas turbines produced high estimated returns. In some applications, diesels were most efficient. The advanced technologies used coal derived fuels, or coal with advanced fluid bed combustion or on site gasifications. Data and information for both current and advanced energy conversion technology are presented. Schematic and physical descriptions, performance data, equipment cost estimates, and predicted emissions are included. Technical developments which are needed to achieve commercialization in the 1985-2000 period are identified.

1980-01-01

The zirconium alloy tube of the impile creep test facility had been subjected to inner pressure in the Japan Material Testing Reactor (JMTR) environment. In the near future, it will be necessary to dismantle the facility and to take out the tube for such examinations as irradiation effects on material properties. In order to establish the dismantling technology for the radioactive facility, a study on underwater plasma arc cutting has been carried out since 1977. Primarily, optimum underwater cutting sequence and conditions were studied in details for developing the remote control handling and the cutting system. Further, the amounts of particles suspended in water as well as those contained in bubbled gas were quantitatively analyzed for developing a safe removal system for contaminants which were produced by cutting the radioactive material. As a result of this study, it has been concluded that the underwater plasma arc cutting method is generally suitable and effective for dismantling such radioactive material as the impile creep test facility of the JMTR.

This paper reports the results of a high-level study to assess the technological readiness and technical and economic feasibility of 17 novel bulk energy storage technologies. The novel technologies assessed were variations of either pumped storage hydropower (PSH) or compressed air energy storage (CAES). The report also identifies major technological gaps and barriers to the commercialization of each technology. Recommendations as to where future R&D efforts for the various technologies are also provided based on each technology's technological readiness and the expected time to commercialization (short, medium, or long term). The U.S. Department of Energy (DOE) commissioned this assessment of novel concepts in large-scale energy storage to aid in future program planning of its Energy Storage Program. The intent of the study is to determine if any new but still unproven bulk energy storage concepts merit government support to investigate their technical and economic feasibility or to speed their commercialization. The study focuses on compressed air energy storage (CAES) and pumped storage hydropower (PSH). It identifies relevant applications for bulk storage, defines the associated technical requirements, characterizes and assesses the feasibility of the proposed new concepts to address these requirements, identifies gaps and barriers, and recommends the type of government support and research and development (R&D) needed to accelerate the commercialization of these technologies.

The aim of this study was to examine what factors affect the acceptance behavior and use of new technologies for rehabilitation by therapists at a large rehabilitation hospital in Canada. A self-administrated paper-based survey was created by adapting scales with high levels of internal consistency in prior research using the Unified Theory of Acceptance and Use of Technology (UTAUT). Items were scored on a 7-point Likert scale, ranging from "strongly disagree (1)" to "strongly agree (7)". The target population was all occupational therapists (OT) and physical therapists (PT) involved with the provision of therapeutic interventions at the hospital. Our research model was tested using partial least squares (PLS) technique. Performance expectancy was the strongest salient construct for behavioral intention to use new technologies in rehabilitation, whereas neither effort expectancy nor social influence were salient constructs for behavioral intention to use new technologies; (4) facilitating condition and behavioral intention to use new technologies were salient constructs for current use of new technologies in rehabilitation, with facilitating condition the strongest salient for current use of new technologies in rehabilitation. In a large rehabilitation hospital where use of new technologies in rehabilitation is not mandatory, performance expectancy, or how the technology can help in therapists' work, was the most important factor in determining therapists' acceptance and use of technologies. However, effort expectancy and social influence constructs were not important, i.e. therapists were not influenced by the degree of difficulty or social pressures to use technologies. Behavioral intention and facilitating condition, or institutional support, are related to current use of new technologies in rehabilitation.

Water Desalination Studies Using Forward Osmosis Technology, A Review

International Nuclear Information System (INIS)

Abou El-Nour, F.H.

2016-01-01

Fresh water and energy shortage represent a great challenge facing the whole world now. To cover the global water demand, an energy-efficient approach is required to be applied in the suitable technology to achieve the shortage in the fresh water demand. Different techniques are used to solve this problem. A mong the different methods applied to desalinate seawater is the osmosis technologies . Although reversible osmosis (RO) is the most familiar method used for this purpose, forward osmosis (FO) represents a more suitable technique due to several arguments including low energy cost. The present study represents the use of FO technique for water desalination with adsorption regeneration. In this respect, a self-prepared granular active carbon produced from dates is to be used as an adsorbent agent. The physical characteristics of the active carbon are studied such as BET specific surface area, pore size, particle size and the structure using scanning electron microscope (SEM). Different advanced apparatus are used for such measurements. In addition, the adsorption is otherms (Langmuier and Freundlich) are established to explain the adsorption mechanism of the process. Accordingly, the review includes essential information and sufficient backgrounds in the field of desalination using FO or simply direct osmosis, which overcome the different difficulties present in reversible RO

Current Highlights on ESA's Planetary Technology Reference Studies

Science.gov (United States)

Falkner, P.

The concept of Technology Reference Studies has been introduced already at EGU05, where the Venus Entry Probe (VEP), the Jupiter Minisat Explorer (JME), the Deimos Sample Return (DSR) and the Interstellar Heliopause Probe (IHP) have been presented in detail. At the EGU06 the new studies in reaction to the Cosmic Vision exercise have been introduced. The formulation of themes and mapping into potential future missions has been taken as basis in the planning of additional new and adaptation of existing TRS's to cover areas, which have not yet been addressed by any TRS. These new ongoing studies are progressing well and current highlights will be presented in the paper in further detail as well as an overview on supporting technology studies and Concurrent Design Facility (CDF) sessions. The Jupiter System Explorer (JSE) study investigates mission concepts with up to two Magnetospheric Orbiters placed in a highly elliptical Jovian orbit and the possibility to deploy a Jovian Entry Probe. The mission profile is based on a solar powered concept launched on a Soyuz-Fregat launcher. Mission analysis and the application of a new Jovian radiation model are supporting the study activities. The Near-Earth Asteroid Sample Return (NEA-SR) concept explores the possibilities of sample return or in-situ mission profiles with visits to up to two NEA targets. Due to the assumed low cost cap a trade between a sample return and remote/in-situ exploration concept has a high attention in the study. The Cross Scale TRS (CS-TRS) is intended to simultaneously investigate magnetospheric and plasma processes in three spatial scales with a formation flight of up to 12 spacecraft, orbiting on deep elliptical orbits around Earth. One of the major challenges is the launch of that number of spacecraft on a single launcher and the collisionless deployment of the formation at the target orbit. The scope if the GeoSail TRS is to demonstrate deployment, attitude control and navigation concepts for a

Smart-home technologies, comprising environmental sensors, wearables and video are attracting interest in home healthcare delivery. Development of such technology is usually justified on the basis of the technology's potential to increase the autonomy of people living with long-term conditions. Studies of the ethics of smart-homes raise concerns about privacy, consent, social isolation and equity of access. Few studies have investigated the ethical perspectives of smart-home engineers themselves. By exploring the views of engineering researchers in a large smart-home project, we sought to contribute to dialogue between ethics and the engineering community. Either face-to-face or using Skype, we conducted in-depth qualitative interviews with 20 early- and mid-career smart-home researchers from a multi-centre smart-home project, who were asked to describe their own experience and to reflect more broadly about ethical considerations that relate to smart-home design. With participants' consent, interviews were audio-recorded, transcribed and analysed using a thematic approach. Two overarching themes emerged: in 'Privacy', researchers indicated that they paid close attention to negative consequences of potential unauthorised information sharing in their current work. However, when discussing broader issues in smart-home design beyond the confines of their immediate project, researchers considered physical privacy to a lesser extent, even though physical privacy may manifest in emotive concerns about being watched or monitored. In 'Choice', researchers indicated they often saw provision of choice to end-users as a solution to ethical dilemmas. While researchers indicated that choices of end-users may need to be restricted for technological reasons, ethical standpoints that restrict choice were usually assumed and embedded in design. The tractability of informational privacy may explain the greater attention that is paid to it. However, concerns about physical privacy may

"Flipped Classroom" is one of the most popular teaching models, and has been applied in more and more curriculums. It is totally different from the traditional teaching model. In the "Flipped Classroom" model, the students should watch the teaching video afterschool, and in the classroom only the discussion is proceeded to improve the students' comprehension. In this presentation, "Flipped Classroom" was studied and practiced in opto-electronic technology curriculum; its effect was analyzed by comparing it with the traditional teaching model. Based on extensive and deep investigation, the phylogeny, the characters and the important processes of "Flipped Classroom" are studied. The differences between the "Flipped Classroom" and the traditional teaching model are demonstrated. Then "Flipped Classroom" was practiced in opto-electronic technology curriculum. In order to obtain high effectiveness, a lot of teaching resources were prepared, such as the high-quality teaching video, the animations and the virtual experiments, the questions that the students should finish before and discussed in the class, etc. At last, the teaching effect was evaluated through analyzing the result of the examination and the students' surveys.

A Study on Diffusion Pattern of Technology Convergence: Patent Analysis for Korea

Directory of Open Access Journals (Sweden)

Jae Young Choi

2015-08-01

Full Text Available Technology convergence indicates that technologies of different application areas are converted into a new and common unity of technology. Its range spans from inter-field, whereby technologies are converged between heterogeneous fields in homogeneous sector, to a wider inter-sector, whereby technologies belong to heterogeneous technology sector are converged. This paper determined the definition of technology convergence from previous literature and classified patents into technology category depending on patent information. Furthermore, we empirically measure technology convergence degree based on co-classification analysis and estimate its diffusion trend at the entire technology domain level by using overall 1,476,967 of patents filed to the KIPO (Korean Intellectual Property Office from 1998 to 2010. As a result, potential size and growth rate of technology convergence are varied by both technology and type of technology convergence, i.e., inter-field and inter-sector technology convergence. Diffusion pattern of inter-sector technology convergence appears as the more various form than that of inter-field technology convergence. In a relationship between potential size and growth rate of technology convergence, growth rate of technology convergence is in inverse proportion to potential size of technology convergence in general. That is, the faster the growth rate of technology convergence, the smaller the potential size of technology convergence. In addition, this paper found that technology convergence of the instrument and chemistry sector is actively progressing in both inter-field and inter-sector convergence, while the technologies related to Information and Communication Technology (ICT in electrical engineering sector have relatively mature progress of technology convergence, especially in inter-sector technology convergence.

Teaching science to 8th graders by engaging them in a design and technology activity: A case study

Science.gov (United States)

Sidawi, Mai M.

This study described how students can apply science concepts to a Design and Technology task. It also examined whether the students could transfer their scientific knowledge to their design of technology. The study was conducted at an urban school in Philadelphia where a sample of 36 eighth grade students were taught a science unit, Energy, Machines, and Motion, and engaged in a technology design task that was chosen based on the scientific content of the unit. Two approaches of relating teaching science to technological design were observed and described. Through the first approach, the students were given technology lessons in addition to their science lessons. This was to provide them with the technological knowledge that they needed in designing technology such as learning about the design process, selection of appropriate materials, and selection of appropriate tools and how to use them. Also, the students were taught the social skills that will enable them to develop an effective collaborative relationship with their peers such as conflict-management and brainstorming. Through the second approach, the students were taught the science unit and then at the end of the unit the students were given the design task as an assessment of their scientific knowledge. The students' experience of designing technology for each approach was described. The study was conducted using multiple tools and instruments such as observation, videotaping, interviews, and testing. The students were also given the survey PATT-USA to measure their attitude toward technology. The study showed that the students' learning of science was impacted by their weak prerequisite knowledge in science, their poor verbal and written communication skills and their style as dependent learners. Also, the study showed the great impact of the school and classroom cultures on the participation of the students in a Design and Technology activity. The students in this study showed great resistant to

An Orchestrating Evaluation of Complex Educational Technologies: a Case Study of a CSCL System

Directory of Open Access Journals (Sweden)

Luis P. Prieto

2014-06-01

Full Text Available As digital technologies permeate every aspect of our lives, the complexity of the educational settings, and of the technological support we use within them, unceasingly rises. This increased complexity, along with the need for educational practitioners to apply such technologies within multi-constraint authentic settings, has given rise to the notion of technology-enhanced learning practice as “orchestration of learning”. However, at the same time, the complexity involved in evaluating the benefits of such educational technologies has also increased, prompting questions about the way evaluators can cope with the different places, technologies, informants and issues involved in their evaluation activity. By proposing the notion of “orchestrating evaluation”, this paper tries to reconcile the often disparate “front office accounts” of research publications and the “shop floor practice” of evaluation of educational technology, through the case study of evaluating a system to help teachers in coordinating computer-supported collaborative learning (CSCL scenarios. We reuse an internationally-evaluated conceptual framework of “orchestration aspects” (design, management, adaptation, pragmatism, etc. to structure the case‟s narrative, showing how the original evaluation questions and methods were modulated in the face of the multiple (authentic evaluation setting constraints.

Discourses of Technology

Sommer, Jannek K.; Knudsen, Gry Høngsmark

In this poster we address consumption of technology from the perspective of failure. A large body of studies of consumption of technology have focused on consumer acceptance (Kozinets, 2008). These studies have identified particular narratives about social and economic progress, and pleasure...... (Kozinets, 2008) as drivers of consumer acceptance of new technology. Similarly, Giesler (2008) has conceptualized consumer acceptance of technology as a form of marketplace drama, in which market ideologies are negotiated between consumers and media discourses. We suggest to study discourses around failed...... technology products to explore the negotiation of the familiar and alien that makes consumers reject or embrace a new technology.

Full Text Available Annotation. Formulation of the problem. An important indicator in the planning of injection works is a particle size distribution of the soil and the very composition of injection. The ideal case is to comply with the injection optimum ratio between the size of particles in solution and injectable medium. This ratio corresponds to complete impregnation of the environment. Today in the field of building technologies known classical methods of grouting with the injection process [9]. This may be a cementation or silicification with different chemical compositions. Due to the fact that we have proposed an innovative technology of impervious curtain device, special attention should be paid to the performance and physical and mechanical properties of the resulting soil-injection. This is due to the fact that the proposed technology provides for lesser known technical solutions, the use of which should ultimately result in impervious screens with desired properties. Goal. The aim of this study is to investigate the properties of the resulting soil-concrete impervious screen. Such structures should have defined a number of physical and mechanical properties. In this paper, it was of interest to study the compressive strength of the resulting soil-concrete structure. Conclusion. As a result of experimentation and implementation of complex obtained experimentally-statistical models that describe the main soil-quality indicators. Based on these data is possible optimal selection of formulation and technological structure for sandy soils with different modules size of its particles.

Our findings corroborate earlier research on technology-use mediation, which suggests that such mediators can exert considerable influence on how a particular technology will be established and used in an organization. However, this study also indicates that the process...... of technology-use mediation is more complex and indeterminate than earlier literature suggests. In particular, we want to draw attention to the fact that advanced computer-mediated communication technologies are equivocal and that technology-use mediation consequently requires ongoing sensemaking (Weick 1995)....

The use of new technology has recently grown considerably as an increasing number of college students using Internet. In nursing education, the personal computer and the Internet facilitate teaching theoretical and practical knowledge. Evaluate an educational technology known as "Anatomy and Vital Signs" with respect to content, appearance and usability. This was a first stage evaluation-by specialists to verify content and functioning, prior to a second validation as to learning by students. A methodological study in which instructional technologists (11 participants) and nursing specialists (17 participants) used the technology in an unguided manner and completed three questionnaires. The evaluation was measured by the difference between disagreement and agreement for each statement in the questionnaires. Most of the items were positively evaluated at a level higher than 70% by most of the evaluators except for the following usability criteria: grouping by shape, minimum actions and user control, which did not attain the 70% agreement level among instructional technologists. The evaluation was useful to improve the technology and guarantee suitable product for nursing education. It may be a reliable educational tool for nursing education that applies technological resources. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

This study examined the longitudinal effects of adolescents' depressive symptoms on engagement in technology-based social comparison and feedback seeking (SCFS) behaviors. A total of 816 adolescents (54.7% girls; M age =14.1 at Time 1) participated at three times points, each one year apart. Adolescents reported technology-based SCFS, depressive symptoms, and frequencies of technology use (cell phones, Facebook, and Instagram). Multiple group (by gender) latent growth curve models examined concurrent and lagged effects of depressive symptoms on SCFS, controlling for adolescent's underlying trajectories of SCFS and overall frequencies of technology use. Results indicated that higher levels of depressive symptoms were concurrently associated with greater SCFS after accounting for adolescents' typical patterns of SCFS. For boys only, higher depressive symptoms were prospectively associated with later increases in SCFS. Results highlight the importance of social media as a unique context in which depressed adolescents may be at risk for maladaptive interpersonal behavior.

Compared with the original ECM, the findings of this study show that the integrated model may offer an ameliorated way to clarify what factors and how they influence the continuous intention toward mobile services. Finally, the major findings are summarized, and future research directions are suggested.

Nowadays, mobile technologies are part of everyday life, but the lack of instruments to assess their acceptability for the management of chronic diseases makes their actual adoption for this purpose slow. The objective of this study was to develop a survey instrument for assessing patients' attitude toward and intention to use mobile technology for diabetes mellitus (DM) self-management, as well as to identify sociodemographic characteristics and quality of life factors that affect them. We first conducted the documentation and instrument design phases, which were subsequently followed by the pilot study and instrument validation. Afterward, the instrument was administered 103 patients (median age: 37 years; range: 18-65 years) diagnosed with type 1 or type 2 DM, who accepted to participate in the study. The reliability and construct validity were assessed by computing Cronbach's alpha and using factor analysis, respectively. The instrument included statements about the actual use of electronic devices for DM management, interaction between patient and physician, attitude toward using mobile technology, and quality of life evaluation. Cronbach's alpha was 0.9 for attitude toward using mobile technology and 0.97 for attitude toward using mobile device applications for DM self-management. Younger patients (Spearman's ρ =-0.429; P higher education level (Kendall's τ =0.51; P mobile assistive applications for DM control. Moreover, patients with a higher quality of life presented a significantly more positive attitude toward using modern technology (Spearman's ρ =0.466; P mobile technology for DM self-management. Additionally, we found that even if most of the patients showed positive attitude toward mobile applications, only a moderate level of intention to indeed use them was observed. Moreover, the study indicated that barriers were truthfulness and easiness to use.

Survey has been conducted to develop laser processing technology utilizing the interaction between substance and photon. This is a part of the leading research on photon technology development. The photon technology development is aimed at novel technology development highly utilizing the quantum nature of photons. In the field of laser processing, high quality photons are used as tools, special functions of atoms and molecules will be discovered, and processing for functional fabrication (photon machining) will be established. A role of laser processing in industries has become significant, which is currently spreading not only into cutting and welding of materials and scalpels but also into such a special field as ultrafine processing of materials. The spreading is sometimes obstructed due to the difficulty of procurement of suitable machines and materials, and the increase of cost. The purpose of this study is to develop the optimal laser technology, to elucidate the interaction between substance and photon, and to develop the laser system and the transmission and regulation systems which realize the optimal conditions. 387 refs., 115 figs., 25 tabs.

Highlights: → Nuclear data are of fundamental importance in studies of nuclear technology. → Data libraries cover: experiments (EXFOR), theory (RIPL) and evaluations (ENDF). → Libraries are general purpose or special purpose (decay, dosimetry and activation). → Activation files contain many reactions, only a fraction needs to be known precisely. → Covariance data are important, but details of formatting are being worked out. - Abstract: Nuclear data are of fundamental importance in studies of nuclear technology. In these studies, experiments to measure cross sections and decay properties and simulations of the design of fission power plants, fusion devices and accelerators are included. The large amount of data required is stored in computer readable formats in data libraries and the most common of these are the general purpose files used for neutronics or transport calculations. These files also contain the standards against which most measurements are made. The other class of libraries are the special purpose ones containing decay data, fission yields and cross section data for dosimetry and activation. This paper gives examples of what data are available and describes their use for various fusion applications. The focus will be on neutron-induced activation data with examples of how the reactions of particular importance can be identified. All data should be accompanied by estimates of the uncertainty. This is best achieved by including covariance data; however, this is extremely challenging and only a subset of the available data has such uncertainty data. The general principles of how covariance matrices are used are outlined.

The primary scope of this study is to establish the analysis technology for the advanced reactor designed on the basis of the passive and inherent safety concepts. This study is extended to the application of these technology to the safety analysis of the passive reactor. The study was performed for the small and medium sized reactor and the large sized reactor by focusing on the development of the analysis technology for the passive components. Among the identified concepts the once-through steam generator, the natural circulation of the integral reactor, heat pipe for containment cooling, and hydraulic valve were selected as the high priority items to be developed and the related studies are being performed for these items. For the large sized passive reactor, the study plans to extend the applicability of the best estimate computer code RELAP5/MOD3 which is widely used for the safety analyses of the reactor system. The improvement and supplementation study of the analysis modeling and the methodology is planned to be carried out for these purpose. The newly developed technologies are expected to be applied to the domestic advanced reactor design and analysis and these technologies will play a key role in extending the domestic nuclear base technology and consolidating self-reliance in the essential nuclear technology. 72 figs, 15 tabs, 124 refs.

The number of new technologies for risk assessment available in health care is increasing. These technologies are intended to contribute to both improved care practices and improved patient outcomes. To do so however, there is a need to study how new technologies are understood and interpreted by users in clinical practice. The objective of this study was to explore patient and physician perspectives on the usefulness of a new technology to detect Cardiovascular Autonomic Neuropathy (CAN) in a specialist diabetes clinic. The technology is a handheld device that measures resting heart rate and conducts three cardiac autonomic reflex tests to evaluate heart rate variability. The study relied on three sources of data: observations of medical consultations where results of the CAN test were reported (n = 8); interviews with patients who had received the CAN test (n = 19); and interviews with physicians who reported results of the CAN test (n = 9). Data were collected at the specialist diabetes clinic between November 2013 and January 2014. Data were analysed using the concept of technological frames which is used to assess how physicians and patients understand and interpret the new technology. Physicians generally found it difficult to communicate test results to patients in terms that patients could understand and to translate results into meaningful implications for the treatment of patients. Results of the study indicate that patients did not recall having done the CAN test nor recall receiving the results. Furthermore, patients were generally unsure about the purpose of the CAN test and the implications of the results. Involving patients and physicians is essential when a new technology is introduced in clinical practice. This particularly includes the interpretation and communication processes related to its use. The integration of a new risk assessment technology into clinical practice can be accompanied by several challenges. It is suggested that

This study focuses on the remediation methods and technologies applicable for use at 200-PO-I Groundwater Operable Unit (OU) at the Hanford Site. The 200-PO-I Groundwater au requires groundwater remediation because of the existence of contaminants of potential concern (COPC). A screening was conducted on alternative technologies and methods of remediation to determine which show the most potential for remediation of groundwater contaminants. The possible technologies were screened to determine which would be suggested for further study and which were not applicable for groundwater remediation. COPCs determined by the Hanford Site groundwater monitoring were grouped into categories based on properties linking them by remediation methods applicable to each COPC group. The screening considered the following criteria. (1) Determine if the suggested method or technology can be used for the specific contaminants found in groundwater and if the technology can be applied at the 200-PO-I Groundwater au, based on physical characteristics such as geology and depth to groundwater. (2) Evaluate screened technologies based on testing and development stages, effectiveness, implementability, cost, and time. This report documents the results of an intern research project conducted by Mathew Dado for Central Plateau Remediation in the Soil and Groundwater Remediation Project. The study was conducted under the technical supervision of Gloria Cummins and management supervision of Theresa Bergman and Becky Austin.

Study on the Evolvement of Technology Development and Energy Efficiency—A Case Study of the Past 30 Years of Development in Shanghai

Full Text Available Previous research in regional energy efficiency by using macro statistical data has demonstrated that technology development could improve regional energy efficiency. Since the start of reform and opening up in 1978, China has mainly adopted energy import and foreign direct investment to promote economic growth. At the same time, the country has also increased the input of technology and R&D to prompt technological reformation and imported technology absorption. However, there is limited research on the relationship between technology development and energy efficiency. Using the grounded theory method, the authors of this paper study the relationship between technology input-output and energy utilization efficiency in Shanghai over the past 30 years. They conclude that although the tactics of technology import and foreign direct investment can improve energy efficiency in the initial stages of modern industrialization, they cannot improve it continuously. In the more advanced stages of modern industrialization, the improvement of energy efficiency relies not only on increased R&D investment but also on R&D investment structure optimization and independent technological innovation.

Science, technology, and pedagogy: Exploring secondary science teachers' effective uses of technology

Science.gov (United States)

Guzey, Siddika Selcen

Technology has become a vital part of our professional and personal lives. Today we cannot imagine living without many technological tools such as computers. For the last two decades technology has become inseparable from several areas, such as science. However, it has not been fully integrated into the field of education. The integration of technology in teaching and learning is still challenging even though there has been a historical growth of Internet access and available technology tools in schools (U.S. Department of Education, National Center for Education Statistics, 2006). Most teachers have not incorporated technology into their teaching for various reasons such as lack of knowledge of educational technology tools and having unfavorable beliefs about the effectiveness of technology on student learning. In this study, three beginning science teachers who have achieved successful technology integration were followed to investigate how their beliefs, knowledge, and identity contribute to their uses of technology in their classroom instruction. Extensive classroom observations and interviews were conducted. The findings demonstrate that the participating teachers are all intrinsically motivated to use technology in their teaching and this motivation allows them to enjoy using technology in their instruction and keeps them engaged in technology use. These teachers use a variety of technology tools in their instruction while also allowing students to use them, and they posit a belief set in favor of technology. The major findings of the study are displayed in a model which indicates that teachers' use of technology in classroom instruction was constructed jointly by their technology, pedagogy, and content knowledge; identity; beliefs; and the resources that are available to them and that the internalization of the technology use comes from reflection. The study has implications for teachers, teacher educators, and school administrators for successful technology

To systematically review and analyze the current status and characteristics of usability studies in China in the field of information technology in general and in the field of healthcare in particular. We performed a quantitative literature analysis in three major Chinese academic databases and one English language database using Chinese search terms equivalent to the concept of usability. Six hundred forty-seven publications were selected for analysis. We found that in China the literature on usability in the field of information technology began in 1994 and increased thereafter. The usability definitions from ISO 9241-11:1998 and Nielsen (1993) have been widely recognized and cited. Authors who have published several publications are rare. Fourteen journals have a publishing rate over 1%. Only nine publications about HIT were identified. China's usability research started relatively late. There is a lack of organized research teams and dedicated usability journals. High-impact theoretical studies are scarce. On the application side, no original and systematic research frameworks have been developed. The understanding and definition of usability is not well synchronized with international norms. Besides, usability research in HIT is rare. More human and material resources need to be invested in China's usability research, particularly in HIT.

Full Text Available As a useful technical measure to deal with the problem of carbon dioxide (CO2 emissions, carbon capture and storage (CCS technology has been highly regarded in both theory and practice under the promotion of the Intergovernmental Panel on Climate Change (IPCC. Knowledge mapping is helpful for understanding the evolution in terms of research topics and emerging trends in a specific domain. In this work knowledge mapping of CCS technology was investigated using CiteSpace. Several aspects of the outputs of publications in the CCS research area were analyzed, such as annual trends, countries, and institutions. The research topics in this particular technology area were analyzed based on their co-occurring keyword networks and co-citation literature networks, while, the emerging trends and research frontiers were studied through the analysis of burst keywords and citation bursts. The results indicated that the annual number of publications in the research field of CCS technology increased rapidly after 2005. There are more CCS studies published in countries from Asia, North America, and Europe, especially in the United States and China. The Chinese Academy of Sciences not only has the largest number of publications, but also has a greater impact on the research area of CCS technology, however, there are more productive institutions located in developed countries. In the research area of CCS technology, the main research topics include carbon emissions and environmental protection, research and development activities, and social practical issues, meanwhile, the main emerging trends include emerging techniques and processes, emerging materials, evaluation of technological performance, and socioeconomic analysis.

Analyzing the Discourse of Chais Conferences for the Study of Innovation and Learning Technologies via a Data-Driven Approach

2016-12-01

Full Text Available The current rapid technological changes confront researchers of learning technologies with the challenge of evaluating them, predicting trends, and improving their adoption and diffusion. This study utilizes a data-driven discourse analysis approach, namely culturomics, to investigate changes over time in the research of learning technologies. The patterns and changes were examined on a corpus of articles published over the past decade (2006-2014 in the proceedings of Chais Conference for the Study of Innovation and Learning Technologies – the leading research conference on learning technologies in Israel. The interesting findings of the exhaustive process of analyzing all the words in the corpus were that the most commonly used terms (e.g., pupil, teacher, student and the most commonly used phrases (e.g., face-to-face in the field of learning technologies reflect a pedagogical rather than a technological aspect of learning technologies. The study also demonstrates two cases of change over time in prominent themes, such as “Facebook” and “the National Information and Communication Technology (ICT program”. Methodologically, this research demonstrates the effectiveness of a data-driven approach for identifying discourse trends over time.

This feasibility study was designed to examine if remote communication technology can be used in the technical training of an insulin pump in adults with diabetes who were familiar with insulin pump therapy. Surveys were emailed to 69 individuals who purchased an insulin pump and had been trained by the manufacturer's diabetes educators. In consultation with providers, participants were given the choice of receiving training in a face-to-face meeting or via remote communication technology. The survey consisted of 27 questions asking participants' characteristics, device proficiency, confidence, and their satisfaction with the insulin pump and the training method. Differences between the 2 groups were examined using bivariate analyses. There were 17 participants in the remote group and 20 participants in the face-to-face group. Participants had a mean age of 40.9 ± 14.3 years, had diabetes for 24.3 ± 13.8 years, and used an insulin pump for 9.8 ± 4.9 years. The participants in both groups were not statistically different in age, diabetes history, years on insulin pump, device proficiency, confidence, or satisfaction with the training method. The remote group reported less graduate-level education (P remote communication technology may be an effective tool to provide technical training to adults who are familiar with insulin pump therapy. Additional research is required to determine the effectiveness of the remote insulin pump training. © 2015 Diabetes Technology Society.

Two natural gas fields have been studied for three different technological solutions using two different economic theories. The aim was to examine whether a new technology for transporting natural gas, Natural Gas Hydrates (NGH), can compete with the existing technologies pipeline and Liquefied Natural Gas (LNG). Natural gas can rarely be used immediately after production and the supply systems can be divided into four interrelated parts: 1) Exploration. 2) Development and production. 3) Transportation. 4) Distribution. The emphasis in the study is on production costs and transportation. Exploration is assumed carried out and thus viewed sunk cost. Distribution from landing point to consumers is not part of the study. Production can take place either onshore or offshore, the natural gas can be transported to the market either by pipeline or ship and the costs are becoming more important as the distance from the fields to the markets increase. Natural gas projects have long lead times and large capital requirements. New supplies will materialise then if there is confidence that demand for the gas exists at a profitable price. Therefore natural gas is generally sold on long term contracts. The conclusions are that economies of scale exist and that pipeline is the superior technology for high volumes but cannot compete for smaller volumes where the LNG technology has been the best alternative. However, the report concludes that the NGH can compete fully. The distance to the market where the natural gas is to be transported is crucial for choice of transportation mode. The shipping modes are superior for long transportation distances. NGH is superior to LNG also with regards to distance. Despite that the two economic models used for the evaluation have provided very different absolute project values, they have provided the same conclusions about the ranking of the different technologies. It is clear then that if NGH technology is developed further into a reliable and

An exploratory study of engagement in a technology-supported substance abuse intervention

Directory of Open Access Journals (Sweden)

VanDeMark Nancy R

2010-06-01

Full Text Available Abstract Background The continuing gap between the number of people requiring treatment for substance use disorders and those receiving treatment suggests the need to develop new approaches to service delivery. Meanwhile, the use of technology to provide counseling and support in the substance abuse field is exploding. Despite the increase in the use of technology in treatment, little is known about the impact of technology-supported interventions on access to services for substance use disorders. The E-TREAT intervention brings together the evidence-based practice of Motivational Interviewing and theories of Persuasive Technology to sustain clients' motivation to change substance use behaviors, provide support for change, and facilitate continuity across treatment settings. Methods This study used descriptive statistics, tests of statistical significance, and logistic regression to explore the characteristics and perceptions of the first 157 people who agreed to participate in E-TREAT and the predictors of their active engagement in E-TREAT services. In addition, responses to open-ended questions about the participants' experiences with the intervention were analyzed. Results The data reveal that clients who engaged in E-TREAT were more likely than those who did not engage to be female, have children and report a positive relationship with their recovery coach, and were less likely to have completed treatment for a substance use disorder in the past. A majority of people engaging in E-TREAT reported that it was helpful to talk with others with similar problems and that the program assisted them in developing a sense of community. Conclusions The authors conclude that technology-assisted interventions hold promise in expanding access to treatment for substance use disorders especially for women and parents.

The purpose of this study was to determine if there is adequate documentation of an historical role of African and African American involvement in science, engineering, and technology. Through the use of history of science and technology research methodology, along with an examination of the sociological and economic impacts of adequately accredited innovations and inventions contributed by Africans and African Americans, the researcher investigated their contributions to the following areas of science and technology: life science, physical sciences and chemistry, engineering, and science education. In regard to the timeframe for this study, the researcher specifically investigated African and African American involvement in science and technology that includes periods prior to black enslavement, scientific racism and colonialism, as well as during and after those periods. This research study reveals that there are adequate historical data regarding African and African American contributions to science, engineering, and technology. The data reveals that for many millennia African peoples have been continually involved in science and world science histories. The data further show that the numbers of African Americans acquiring BS, MS, Ph.D., Doctor of Science and Doctor of Engineering degrees in science and engineering disciplines are increasing. That these increases are not happening at a rate representative of the present or future African American percentages of the population. Consequently, because of future changes in our nation's demographics, increasing the numbers of people from under-represented groups who pursue scientific and engineering professions has become a matter of national security at the highest levels of government. Moreover, African Americans, Hispanics, and Native Americans are not pursuing careers or taking courses in science and engineering at a rate high enough to fulfill the prospective needs for the United States' industries, government

The project was launched to identify barriers to the implementation of renewable energy technologies (RETs) and explore measures to overcome the identified barriers. National institutions in Egypt, Ghana and Zimbabwe carried out the country studies based on the basic methodological framework provided by the UNEP Centre. The objectives of the project included strengthening institutional capacity for analysis and implementation of RET projects in the participating countries and bring out experiences on RETs barriers and removal measures for dissemination so that others can benefit from the knowledge so gained. An important highlight of the studies was involvement of stake holders in the process of identification of barriers and measures to remove them. A preliminary identification of relevant RETs for their countries was done by the country teams in the initial stage of the project. After that, national workshops involving various stake holders were held between July and September 1999 to discuss the RETs and barriers to their implementation. Based on the discussions, a few important RETs were identified for more detailed study. PV systems for rural electrification, solar water heating systems and large-scale biogas system were identified and analysed for barriers in the Egypt country study. Economic, information and policy barriers were identified as major barriers for these technologies. Solar water pumps, biogas and small hydro were the focus of study in Ghana. In this case also, economic, information and policy barriers were found to be the important barriers for the selected technologies. In the case of Zimbabwe, focus was on identification of primary and secondary barriers to RETs dissemination. The primary barriers included lack of capacity to develop proposals, lack of information for policy making and framework for information dissemination. The study concluded that the secondary barriers as seen and experienced by the stake holders are due to primary
