  1. Hurdling barriers through market uncertainty: Case studies ininnovative technology adoption

    SciTech Connect

    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.

    Jolivet, Noel D.; Hansen, Joel; Miller, John Lester; Beniga, Rico; Austria, Rich

    2014-06-01

    Infrared technology and imaging systems are already used extensively by the law enforcement (LE) community, typically to gain a tactical advantage or obtain immediate situational awareness. As the use of infrared technology becomes more affordable and widespread, LE is finding new ways to use it and leverage the results in the courtroom as evidence. A case study will be presented where infrared imagery was used to support the Portland Police Bureau (PPB) in prosecuting an individual for a crime where a conviction might not have been assured without said imagery. Tests conducted at FLIR Systems, combined with expert witness testimony by a FLIR employee, helped a jury understand the significance of a key piece of infrared evidence, resulting in a conviction of the criminal. This case was the first Federal case of its kind where infrared imagery was used forensically as evidence and, as such, established precedence. Prior to this, infrared imagery has been offered and debated in court only as to whether it constitutes a legal search. Courtroom observations and lessons learned from this trial have shown that both industry and LE can do a better job of making the prosecution's cases stronger utilizing infrared technology and thus taking criminals off the street.

  4. Technology transfer for Ukrainian milk treatment: A case study

    SciTech Connect

    Dunn, M.J.; Walker, J.S.

    1994-12-31

    As a result of the Chernobyl Nuclear Power Plant accident, radioactive fission products have contaminated the food chain in the Ukraine. The highest doses to humans are a result of cesium contamination in milk. The milk produced in the Ukraine contains radioactive cesium at levels up to 10 times the acceptance standards. Bradtec has developed and demonstrated technology for the US Department of Energy for the treatment of groundwater and effluent water. This technology has also been tested and demonstrated for the Ukrainian government for the purpose of treating contaminated milk. Bradtec, a small business offering specialized technologies in the field of environmental remediation and waste management, has successfully worked with a consortium of businesses, National Laboratories and DOE Headquarters staff to develop and implement a technology demonstration strategy which has led to the implementation of a series collaboration agreements with Ukrainian officials. This paper describes, in a case study approach, the path followed by Bradtec and its collaboration partners in successfully implementing a technology transfer strategy. Also presented is an update on new programs that can provide benefit to private sector companies as DOE seeks to assist the private sector in joint venture/technology transfer relationships with the NIS (New Independent States). This paper should be of interest to all businesses seeking to participate in business opportunities in the NIS.

    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.

  17. BICAPA case study of natural hazards that trigger technological disasters

    NASA Astrophysics Data System (ADS)

    Boca, Gabriela; Ozunu, Alexandru; Nicolae Vlad, Serban

    2010-05-01

    Industrial facilities are vulnerable to natural disasters. Natural disasters and technological accidents are not always singular or isolated events. The example in this paper show that they can occur in complex combinations and/or in rapid succession, known as NaTech disasters, thereby triggering multiple impacts. This analysis indicates that NaTech disasters have the potential to trigger hazmat releases and other types of technological accidents. Climate changes play an important role in prevalence and NATECH triggering mechanisms. Projections under the IPCC IS92 a scenario (similar to SRES A1B; IPCC, 1992) and two GCMs indicate that the risk of floods increases in central and eastern Europe. Increase in intense short-duration precipitation is likely to lead to increased risk of flash floods. (Lehner et al., 2006). It is emergent to develop tools for the assessment of risks due to NATECH events in the industrial processes, in a framework starting with the characterization of frequency and severity of natural disasters and continuing with complex analysis of industrial processes, to risk assessment and residual functionality analysis. The Ponds with dangerous technological residues are the most vulnerable targets of natural hazards. Technological accidents such as those in Baia Mare, (from January to March 2000) had an important international echo. Extreme weather phenomena, like those in the winter of 2000 in Baia Mare, and other natural disasters such as floods or earthquakes, can cause a similar disaster at TĆ¢rnăveni in Transylvania Depression. During 1972 - 1978 three decanting ponds were built on the Chemical Platform TĆ¢rnăveni, now SC BICAPA SA, for disposal of the hazardous-wastes resulting from the manufacture of sodium dichromate, inorganic salts, sludge from waste water purification and filtration, wet gas production from carbide. The ponds are located on the right bank of the river TĆ¢rnava at about 35-50m from the flooding defense dam. The total amount of toxic waste stored in the three ponds is about 2500 tons, equivalent at 128 tons expressed in hexavalent chromium. The ponds contour dikes are strongly damaged in many places, their safety is jeopardized by leakages, sliding slopes and ravens. The upstream dike has an increased failure risk. The upstream dike has an increased failure risk. In that section the coefficients of safety are under the allowable limit, both in static applications, and the earthquake. The risk of failure is very high also due to the dikes slopes. The risk becomes higher in case of heavy rainfall, floods or an earthquake.

  18. Technology commercialization cost model and component case study

    NASA Astrophysics Data System (ADS)

    1991-12-01

    Fuel cells seem poised to emerge as a clean, efficient, and cost competitive source of fossil fuel based electric power and thermal energy. Sponsors of fuel cell technology development need to determine the validity and the attractiveness of a technology to the market in terms of meeting requirements and providing value which exceeds the total cost of ownership. Sponsors of fuel cell development have addressed this issue by requiring the developers to prepare projections of the future production cost of their fuel cells in commercial quantities. These projected costs, together with performance and life projections, provide a preliminary measure of the total value and cost of the product to the customer. Booz-Allen & Hamilton Inc. and Michael A. Cobb & Company have been retained in several assignments over the years to audit these cost projections. The audits have gone well beyond a simple review of the numbers. They have probed the underlying technical and financial assumptions, the sources of data on material and equipment costs, and explored issues such as the realistic manufacturing yields which can be expected in various processes. Based on the experience gained from these audits, DOE gave Booz-Allen and Michael A. Cobb & company the task to develop a criteria to be used in the execution of future fuel cell manufacturing cost studies. It was thought that such a criteria would make it easier to execute such studies in the future as well as to cause such studies to be more understandable and comparable.

  11. Technology management: case study of an integrated health system.

    PubMed

    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-service contracts with the manufacturer, insurance coverage, time and materials, and independent service vendors/in-house support. Careful consideration of all the ramifications of each option is warranted because there are substantial cost differences among these methods. At SHS, technology management efforts resulted in equipment purchases and maintenance negotiations representing savings of more than $1.5 million in a single year. SHS undertakes an intensive review of purchases and maintenance expenditures, using the techniques described in this report, with the objective of reducing expenses by 10% per year. This report describes the technology management methods that SHS uses to achieve these results. PMID:10139509

  12. Healthcare Reform, Quality, and Technology: ADHD as a Case Study

    PubMed Central

    Epstein, Jeffery N.; Kelleher, Kelly

    2013-01-01

    The concepts of healthcare reform and population health are shifting the emphasis from traditional, volume-based care to a model in which value, or quality, predominates. High quality care will be increasingly rewarded, with financial consequences for poor performance. This shift will be accelerated by the use of healthcare technology, a rapidly growing industry with tools ranging from electronic health records to smart phones and web portals. In this article we highlight pertinent legislative reforms followed by a review of technologies that may play a role in the implementation of these reforms. Pediatric Attention Deficit Hyperactivity Disorder is used as an example given the large number of proposed tools for this condition. While the evidence base is weak for some technologies, research regarding web portals is better developed and will be presented as an example of a technology that may allow practitioners and organizations to improve healthcare quality in several dimensions.

    1993-01-01

    This report represents the preliminary effort in studying the significance of recognition for innovators of spinoff technologies. The purpose of this initial year's effort in this area was to gather preliminary data and define the direction for the remainder of the research. This report focuses on the most recent recipients of the Hall of Fame Award, the developers of liquid-cooled garments. Liquid-cooled garments technology and its spinoffs were used as a case study to define and explore the factors involved in technology transfer and to consider the possible incentives in developing commercial applications including the Hall of Fame Award. Through interviews, views of award recipients were obtained on factors encouraging spinoffs as well as impediments to spinoffs. The researchers observed complex inter-relationships among the significant entities (government, individuals, large and small business), the importance of people, the importance of resource availability, and the significance of intrinsic motivation; drew preliminary conclusions pertaining to the direct and indirect influence of recognition like the Hall of Fame Award; and planned the direction for next year's follow-on research.

  1. Technology installation review. A case study on energy-efficient technologies

    SciTech Connect

    Baxter, Van

    2001-12-31

    The purpose of this Technology Installation Review is to provide an overview of hybrid geothermal heat pump systems. It presents the results of recent research on these systems, looks at system types, energy savings, maintenance considerations, and measured technology performance from several examples. Using the ground as a thermal energy source and/or a heat sink for heat pumps has long been recognized to have a number of advantages over the similar use of ambient air. Ground temperatures at about 3-ft depth or lower are much less variable than ambient air temperatures. Further, soil or rock at these depths is usually warmer than ambient air during the coldest winter months and cooler than ambient air during the summer months. This fact leads directly to cooler condensation temperatures (during cooling operation) and warmer evaporating temperatures (during heating) for a heat pump with consequent improved energy efficiency. It also results in increased heating and cooling capacity at extreme temperatures, thereby reducing or eliminating the need for auxiliary heat.

    This paper describes how an idea for technology education materials developed into a process for producing unique curriculum modules for teaching technology in a gender-inclusive way to primary children. Using a case-study format, the paper describes the interaction between participants, the sequential evolution of the materials themselves and the degree to which success was achieved in terms of the original goals. The study demonstrates how an awareness of gender bias needs to be a feature from the earliest stages of curriculum development, through to the trialling and modification stages. The curriculum materials were a product of effective cooperation between teachers, science educators and community representatives. They utilise a ā€œprocessā€ approach to the teaching of technology and in this presentation, we demonstrate how this same approach is a useful framework for describing this particular curriculum development.

    Environmental modelers are testing and evaluating a prototype land cover characteristics database for the conterminous United States developed by the EROS Data Center of the U.S. Geological Survey and the University of Nebraska Center for Advanced Land Management Information Technologies. This database was developed from multi temporal, 1-kilometer advanced very high resolution radiometer (AVHRR) data for 1990 and various ancillary data sets such as elevation, ecological regions, and selected climatic normals. Several case studies using this database were analyzed to illustrate the integration of satellite remote sensing and geographic information systems technologies with land-atmosphere interactions models at a variety of spatial and temporal scales. The case studies are representative of contemporary environmental simulation modeling at local to regional levels in global change research, land and water resource management, and environmental simulation modeling at local to regional levels in global change research, land and water resource management and environmental risk assessment. The case studies feature land surface parameterizations for atmospheric mesoscale and global climate models; biogenic-hydrocarbons emissions models; distributed parameter watershed and other hydrological models; and various ecological models such as ecosystem, dynamics, biogeochemical cycles, ecotone variability, and equilibrium vegetation models. The case studies demonstrate the important of multi temporal AVHRR data to develop to develop and maintain a flexible, near-realtime land cover characteristics database. Moreover, such a flexible database is needed to derive various vegetation classification schemes, to aggregate data for nested models, to develop remote sensing algorithms, and to provide data on dynamic landscape characteristics. The case studies illustrate how such a database supports research on spatial heterogeneity, land use, sensitivity analysis, and scaling issues involving regional extrapolations and parameterizations of dynamic land processes within simulation models.

    Recent literature has shown the possibility of enabling individuals with multiple disabilities to make telephone calls independently via computer-aided telephone technology. These two case studies assessed a modified version of such technology and a commercial alternative to it for a woman and a man with multiple disabilities, respectively. The modified version used in Study 1 (a) presented the names of the persons available for a call and (b) reminded the participant of the response she needed to perform (i.e., pressing a microswitch) if she wanted to call any of those names/persons. The commercial device used in Study 2 was a Galaxy S3 (Samsung) equipped with the S-voice module, which allowed the participant to activate phone calls by uttering the word "Call" followed by the name of the persons he wanted to call. The results of the studies showed that the participants learned to make phone calls independently using the technology/device available. Implications of the results are discussed. PMID:25153758

    Energy Information Systems (EIS), which can monitor and analyze building energy consumption and related data throughout the Internet, have been increasing in use over the last decade. Though EIS developers describe the capabilities, costs, and benefits of EIS, many of these descriptions are idealized and often insufficient for potential users to evaluate cost, benefit and operational usefulness. LBNL has conducted a series of case studies of existing EIS and related technology installations. This study explored the following questions: (1) How is the EIS used in day-to-day operation? (2) What are the costs and benefits of an EIS? (3) Where do the energy savings come from? This paper reviews the process of these technologies from installation through energy management practice. The study is based on interviews with operators and energy managers who use EIS. Analysis of energy data trended by EIS and utility bills was also conducted to measure the benefit. This paper explores common uses and findings to identify energy savings attributable to EIS, and discusses non-energy benefits as well. This paper also addresses technologies related to EIS that have been demonstrated and evaluated by LBNL.

    Abstract Purpose: This case study describes how an individual with spastic quadriplegic cerebral palsy was trained over a period of four weeks to use a commercial electroencephalography (EEG)-based brain-computer interface (BCI). Method: The participant spent three sessions exploring the system, and seven sessions playing a game focused on EEG feedback training of left and right arm motor imagery and a customised, training game paradigm was employed. Results: The participant showed improvement in the production of two distinct EEG patterns. The participant's performance was influenced by motivation, fatigue and concentration. Six weeks post-training the participant could still control the BCI and used this to type a sentence using an augmentative and alternative communication application on a wirelessly linked device. Conclusions: The results from this case study highlight the importance of creating a dynamic, relevant and engaging training environment for BCIs. Implications for Rehabilitation Customising a training paradigm to suit the users' interests can influence adherence to assistive technology training. Mood, fatigue, physical illness and motivation influence the usability of a brain-computer interface. Commercial brain-computer interfaces, which require little set up time, may be used as access technology for individuals with severe disabilities. PMID:25270615

    Objectives To understand organisational technology adoption (initiation, adoption decision, implementation) by looking at the different types of innovation knowledge used during this process. Design Qualitative, multisite, comparative case study design. Setting One primary care and 11 acute care organisations (trusts) across all health regions in England in the context of infection prevention and control. Participants and data analysis 121 semistructured individual and group interviews with 109 informants, involving clinical and non-clinical staff from all organisational levels and various professional groups. Documentary evidence and field notes were also used. 38 technology adoption processes were analysed using an integrated approach combining inductive and deductive reasoning. Main findings Those involved in the process variably accessed three types of innovation knowledge: ā€˜awarenessā€™ (information that an innovation exists), ā€˜principlesā€™ (information about an innovation's functioning principles) and ā€˜how-toā€™ (information required to use an innovation properly at individual and organisational levels). Centralised (national, government-led) and local sources were used to obtain this knowledge. Localised professional networks were preferred sources for all three types of knowledge. Professional backgrounds influenced an asymmetric attention to different types of innovation knowledge. When less attention was given to ā€˜how-toā€™ compared with ā€˜principlesā€™ knowledge at the early stages of the process, this contributed to 12 cases of incomplete implementation or discontinuance after initial adoption. Conclusions Potential adopters and change agents often overlooked or undervalued ā€˜how-toā€™ knowledge. Balancing ā€˜principlesā€™ and ā€˜how-toā€™ knowledge early in the innovation process enhanced successful technology adoption and implementation by considering efficacy as well as strategic, structural and cultural fit with the organisation's context. This learning is critical given the policy emphasis for health organisations to be innovation-ready. PMID:22492183

    One of the problems in health care in developing countries is the bad accessibility of medicine in pharmacies for patients. Since this is mainly due to a lack of organization and information, it should be possible to improve the situation by introducing information and communication technology. However, for several reasons, standard solutions are not applicable here. In this paper, we describe a case study in Benin, a West African developing country. We identify the problem and the existing obstacles for applying standard ECommerce solutions. We develop an adapted system approach and describe a practical test which has shown that the approach has the potential of actually improving the pharmaceutical care delivery. Finally, we consider the security aspects of the system and propose an organizational solution for some specific security problems. PMID:21519942

    Much literature surrounding medical technology and adherence posits that technology is a mechanism for social control. This assumes that the medical establishment can take away patients' agency. Although power relationships and social control can play a key role, medical technology can also serve as an agentive tool to be utilized. We (1) offer the alternative framework of Actor Network Theory to view medical technology, (2) discuss the literature on medication adherence and technology, (3) delve into the ramifications of looking at adherence as a network and (4) use Digital Pills as a case study of dispersed agency.

    This article is the first of a series of articles detailing the development of near-infrared (NIR) methods for solid-dosage form analysis. Experiments were conducted at the Duquesne University Center for Pharmaceutical Technology to qualify the capabilities of instrumentation and sample handling systems, evaluate the potential effect of one source of a process signature on calibration development, and compare the utility of reflection and transmission data collection methods. A database of 572 production-scale sample spectra was used to evaluate the interbatch spectral variability of samples produced under routine manufacturing conditions. A second database of 540 spectra from samples produced under various compression conditions was analyzed to determine the feasibility of pooling spectral data acquired from samples produced at diverse scales. Instrument qualification tests were performed, and appropriate limits for instrument performance were established. To evaluate the repeatability of the sample positioning system, multiple measurements of a single tablet were collected. With the application of appropriate spectral preprocessing techniques, sample repositioning error was found to be insignificant with respect to NIR analyses of product quality attributes. Sample shielding was demonstrated to be unnecessary for transmission analyses. A process signature was identified in the reflection data. Additional tests demonstrated that the process signature was largely orthogonal to spectral variation because of hardness. Principal component analysis of the compression sample set data demonstrated the potential for quantitative model development. For the data sets studied, reflection analysis was demonstrated to be more robust than transmission analysis. PMID:16353986

    The work done at ORA for NASA-LRC in the design and formal verification of a hardware implementation of a scheme for attaining interactive consistency (byzantine agreement) among four microprocessors is presented in view graph form. The microprocessors used in the design are an updated version of a formally verified 32-bit, instruction-pipelined, RISC processor, MiniCayuga. The 4-processor system, which is designed under the assumption that the clocks of all the processors are synchronized, provides software control over the interactive consistency operation. Interactive consistency computation is supported as an explicit instruction on each of the microprocessors. An identical user program executing on each of the processors decides when and on what data interactive consistency must be performed. This exercise also served as a case study to investigate the effectiveness of reusing the technology which was developed during the MiniCayuga effort for verifying synchronous hardware designs. MiniCayuga was verified using the verification system Clio which was also developed at ORA. To assist in reusing this technology, a computer-aided specification and verification tool was developed. This tool specializes Clio to synchronous hardware designs and significantly reduces the tedium involved in verifying such designs. The tool is presented and how it was used to specify and verify the interactive consistency circuit is described.

    The effective utilization of the limited scarce bandwidth resources allocated by a spectrum regulator usually the Nigerian Communications Commissions (NCC) in Nigeria universities is paramount in maximizing the usage of the expensive scarce bandwidth resources. A significant bandwidth allocation is needed in order to meet up with the challenges of the day and the task of networking, communicating and reaching the word in our universities. Therefore, bandwidth management becomes necessary and essential. This paper contributes in that direction by surveying the bandwidth utilization at Federal University of Technology Minna campus with the hope of proffering a general solution that can be adopted in Nigerian universities for effective bandwidth management. Also, factors that hindered the development of most Nigeria universities are also examined. The federal university of technology minna which is structured like all other universities in the country in terms of the bandwidth requirement was choosing as a case study for this research work. Furthermore, some policies which can be adopted in order to effectively manage the scarce bandwidth resources in Nigerian universities are also proposed.

  4. A Case Study of the Use of Internet Photobook Technology to Enhance Early Childhood "Scientist" Identity

    2011-10-01

    There are many influences on a child's identity. Photobook technology purposefully prepared around science explorations presents a modern opportunity to repeatedly trigger memories that reinforce the "me, as scientist" viewpoint. Semi-structured interviews at 6 and 8 years of age were conducted with a child who was the subject of a photobook of everyday science activities to gain insights into his thinking about the nature of science and how he interprets his younger self participating. Interview data were recorded, transcribed and analyzed using dimensions from the previously established parameters for the nature of science. The child's statements about his participation in the photos were matched to these dimensions to consider how he sees himself "doing science" through his early years. Preliminary findings suggest that the child recognizes elements of science and regards himself as an active participant. In both interviews, the child reinforces these views by the opportunity to revisit the experiences in the photobook. Affective components may motivate further science involvement as well: the child enjoyed the time and attention that the photos and discussion provided; the child took pride in being the subject of a book. This case study suggests that there is a fertile field of research to investigate how, for whom, and in what ways internet photobook technology may enhance a child's developing identity as capable science explorer.

  5. Origami in Education Enhanced by Computer Technology: A Case Study of Teaching Hexaflexagon in Math Class

    This paper reports an experience of the author teaching high school 3D geometry with origami. In this case, students were originally expected to construct a 3D-hexaflexagon by imitating video tape so that they can understand some related math concepts better. However students demonstrated strong willing of exploring the concerned enchanting paper craft. They did not want to just memorize the folding procedures or be limited within verifying some math concepts. The teacher had then to extend the class time to 2 class periods, so that a series of creative activities are invited in. After the primary goals have been reached, two extra activities were launched. First, by exploring a torus forming animation, they explored a different algorithm of forming a hexaflexagon. Secondly, when another animation of Hexaflexagon made by the teacher was presented, the students can then explore the function of the slope of the creases. Some smart students found hexaflexagons with different shape or even different type. So the thinking level of the students reached the highest creating level by curriculum re-design. This case study comes to the conclusions that origami as well as good questions motivate students' higher level thinking. As students' scaffolds, video and animation technology are essential in helping the learners understanding origami in right perspectives.

    The objectives of this research are to improve raw material and energy consumption efficiency, as well as reduce defects and the use of chemicals in the arm coil assembly process of hard disk drive manufacturing in the case study company by applying the Cleaner Technology concepts. The four main sequential steps used in this research were: (1) pre-assessment, (2) assessment, (3) feasibility study, and (4) implementation. In the first step, raw data, such as process flows, raw material usage and defects data were collected. In the second step, the loss during production and causes of loss were analyzed. Opportunities to reduce raw material, chemical and energy wastage could then be recommended. The next step was to evaluate the feasibility and potential benefits of a particular Cleaner Technology opportunity. Finally, in the last step, after a thorough evaluation and implementation of the opportunities to apply Cleaner Technology, the results showed that arm coil defects could be reduced by improving the production process using the ECRS technique. ECRS stands for Eliminate, Combine, Rearrange and Simplify. This improvement reduced arm coil defect rates from 0.48% to 0.15%, thus saving approximately 139,638 Thai Baht per month. In addition, production stoppage decision made by workers was used to increase employee involvement in defect detection. Allowing workers to participate in such a decision was an effective way to reduce defect rate and could motivate workers to produce a better quality job. This resulted in arm coil defects reducing from 0.41% to 0.025%, with about 74,562 Thai Baht per month saving. Additionally, an increase in the efficiency of electricity consumption occurred, by increasing the speed of the infrared oven conveyor belt, improving average productivity from 533 pieces/hour to 560 pieces/hour, without adversely affecting product costs and quality, thus producing products of up to the value of 206,242 Thai Baht per month. Furthermore, the new two-layer curing equipment was designed, developed and used. The upper layer of the equipment was used for arm curing and the lower layer was used for arm coil curing. The result of using such equipment led to a saving of approximately 25,502 Thai Baht per month in electricity costs, without affecting product quality. The outcome of these Cleaner Technology applications was that total costs of approximately 239,702 Thai Baht per month were able to be saved.

    In this paper the Institute for Surface Chemistry is presented with respect to its interaction with industry. The purpose of this paper is to learn what possible impediments can be foreseen for the commercial development of space by using the Institute's experiences of technology transfer. The Institute for Surface Chemistry is a commercial research institute that performs research in the field of surface and colloid chemistry in order to serve the industry with technology and knowledge, i.e. both know how and know why. It is concluded that in order to achieve a successful technology transfer to industry the customer needs must be understood by the researcher. Through a proper understanding the transferred research will be industrially oriented, delivered in time and, in many cases kept confidential. Furthermore, in order to achieve a good communication, the choice of wording and concepts that sell have been found to be very important.

    In order to transfer technology efficiently, it is essential to define the cultural context in which the technologies have been developed and currently reside. As a participant in the International Technology Exchange Program (ITEP), the Environmental Planning Group, Inc. (EPG), had the opportunity to study environmental and energy programs in Russia. EPG found that the unstable political situation in Russia, the inadequate funding in the Russian scientific community, and the withdrawal of government support for research have created new opportunities for accessing technology. EPG concluded that knowledge of the structure of the government and the organization of the scientific community and an understanding of current business practices are fundamental to the creation of successful technology transfer mechanisms.

    PubMed

    Sublette, K L; Kolhatkar, R; Raterman, K

    1998-01-01

    Thiobacillus denitrificans has been shown to be an effective biocatalyst for the treatment of a variety of sulfide-laden waste streams including sour water, sour gases, and refinery spent-sulfidic caustics. The term 'sour' originated in the petroleum industry to describe a waste contaminated with hydrogen sulfide or salts of sulfide and bisulfide. The microbial treatment of sour waste streams resulting from the production or refining of natural gas and crude oil have been investigated in this laboratory for many years. The application of this technology to the treatment of sour wastes on a commercially useful scale has presented several technical barriers including substrate inhibition (sulfide), product inhibition (sulfate), the need for septic operation, biomass recycle and recovery, mixed waste issues, and the need for large-scale cultivation of the organism for process startup. The removal of these barriers through process improvements are discussed in terms of a case study of the full-scale treatment of sulfide-rich wastewater. The ability of T. denitrificans to deodorize and detoxify an oil-field produced water containing sulfides was evaluated under full-scale field conditions at Amoco Production Co. Salt Creek Field in Midwest, WY. More than 800 m3/d of produced water containing 100 mg/L sulfide and total dissolved solids of 4800 mg/L were successfully biotreated in an earthen pit (3000 m3) over a six-month period. Complete removal of sulfides and elimination of associated odors were observed. The system could be upset by severe hydraulic disturbances; however, the system recovered rapidly when normal influent flow rates were restored. PMID:10022069

    Use cases, information modeling, and linked data techniques are Semantic Web technologies used to develop a prototype system that integrates scientific observations from four independent USGS and cooperator data systems. The techniques were tested with a use case goal of creating a data set for use in exploring potential relationships among freshwater fish populations and environmental factors. The resulting prototype extracts data from the BioData Retrieval System, the Multistate Aquatic Resource Information System, the National Geochemical Survey, and the National Hydrography Dataset. A prototype user interface allows a scientist to select observations from these data systems and combine them into a single data set in RDF format that includes explicitly defined relationships and data definitions. The project was funded by the USGS Community for Data Integration and undertaken by the Community for Data Integration Semantic Web Working Group in order to demonstrate use of Semantic Web technologies by scientists. This allows scientists to simultaneously explore data that are available in multiple, disparate systems beyond those they traditionally have used.

    2009-01-01

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

  16. Introducing time delay in the evolution of new technology: the case study of nanotechnology

    NASA Astrophysics Data System (ADS)

    Georgalis, Evangelos E.; Aifantis, Elias C.

    2013-12-01

    Starting with Feynman's "There's Plenty of Room at the Bottom" prophetic lecture at Caltech in the 1960s, the term "nanotechnology" was first coined in the scientific literature in the 1980s. This was followed by the unprecedented growth in the corresponding scientific field in 2000 due to the financial incentive provided by President Clinton in the US, followed up by similar efforts in Europe, Japan, China and Russia. Today, nanotechnology has become a driving force for economic development, with applications in all fields of engineering, information technology, transport and energy, as well as biology and medicine. Thus, it is important to forecast its future growth and evolution on the basis of two different criteria: (1) the government and private capital invested in related activities, and (2) the number of scientific publications and popular articles dedicated to this field. This article aims to extract forecasts on the evolution of nanotechnology, using the standard logistic equation that result in familiar sigmoid curves, as well as to explore the effect of time delay on its evolution. Time delay is commonly known from previous biological and ecological models, in which time lag is either already known or can be experimentally measured. In contrast, in the case of a new technology, we must first define the method for determining time delay and then interpret its existence and role. Then we describe the implications that time delay may have on the stability of the sigmoidal behavior of nanotechnology evolution and on the related oscillations that may appear.

  17. Understanding the interrelationship of instructional technology use and organizational culture: a case study of a veterinary medical college.

    Stansberry, Susan L; Harris, Edward L

    2005-01-01

    Many predicted that in the latter part of the twentieth century modern technology would revolutionize higher education and "create a second Renaissance" (Sculley J. The relationship between business and higher education: A perspective on the 21st century. Commun ACM32:1056-1061, 1989 p1061). However, as the reality of the twenty-first century has set in, it is apparent that these revolutionary prophecies have fallen short. Using the lens of Douglas's Typology of Grid and Group, this case study examines (1) the organizational context of a veterinary medical college at a large Midwestern university; (2) individual faculty members' preferences toward instructional technology use; and (3) the interrelationship of culture and the decision process to implement instructional technology use in curricula. The study has several implications for instructional technology use in veterinary medical educational settings that help explain how cultural context can guide leadership decisions as well as influence faculty motivation and preference. The findings suggest that a key mitigating factor to instructional technology implementation is conflict or concord between the cultural biases of faculty members and actual cultural identity of the college (Stansberry S, Harris EL. Understanding why faculty use (or don't use) IT: Implementation of instructional technology from an organizational culture perspective.

  18. Globalisation of birth markets: a case study of assisted reproductive technologies in India

    PubMed Central

    2011-01-01

    The escalation of Assisted Reproductive Technologies (ARTs) in India into a veritable fertility industry is the result of a multitude of reasons. This paper places the bio-genetic industry within the larger political economy framework of globalisation and privatisation, thus employing a framework that is often omitted from discussions on ARTs, but has direct and significant bearings on the ART industry in India. As markets for human organs, tissues and reproductive body parts experience unprecedented growth, the limits of what can or should be bought and sold continue to be pushed. As such, bodies have emerged as sale-worthy economic capital. Commercial flows of reproductive material create and deploy the division of the body into parts over which ownership is claimed, in the process following 'modern routes of capital' and raising issues of structural inequality. This paper presents a brief picture of India's fertility industry with specific focus on its ground-level operation, nature and growth. It aims to explore the industry dimensions of ARTs, by highlighting the macro picture of health care markets and medical tourism in India, the proliferation of the ART industry, market features such as the social imperative to mother, costs, promotion and marketing, unverified claims, inflated success rates, deals and offers, actors and collaborations in the field, and finally, the absence of standards. This paper presents findings from the research 'Constructing Conceptions: The Mapping of Assisted Reproductive Technologies in India', by Sama, a Delhi-based resource group working on gender, health and rights. This research was conducted from 2008 to 2010 in the three states of Uttar Pradesh, Orissa and Tamil Nadu in India, and is one of the first of its kind, highlighting unethical medical practices and making a case for the regulation of the ART industry. As such, it forms a significant part of Sama's ongoing work on women and technologies, particularly policy-level advocacy. PMID:21838866

  10. An evaluation of soil erosion hazard: A case study in Southern Africa using geomatics technologies

    NASA Astrophysics Data System (ADS)

    Eiswerth, Barbara Alice

    Accelerated soil erosion in Malawi, Southern Africa, increasingly threatens agricultural productivity, given current and projected population growth trends. Previous attempts to document soil erosion potential have had limited success, lacking appropriate information and diagnostic tools. This study utilized geomatics technologies and the latest available information from topography, soils, climate, vegetation, and land use of a watershed in southern Malawi. The Soil Loss Estimation Model for Southern Africa (SLEMSA), developed for conditions in Zimbabwe, was evaluated and used to create a soil erosion hazard map for the watershed under Malawi conditions. The SLEMSA sub-models of cover, soil loss, and topography were computed from energy interception, rainfall energy, and soil erodibility, and slope length and steepness, respectively. Geomatics technologies including remote sensing and Geographic Information Systems (GIS) provided the tools with which land cover/land use, a digital elevation model, and slope length and steepness were extracted and integrated with rainfall and soils spatial information. Geomatics technologies enable rapid update of the model as new and better data sets become available. Sensitivity analyses of the SLEMSA model revealed that rainfall energy and slope steepness have the greatest influence on soil erosion hazard estimates in this watershed. Energy interception was intermediate in sensitivity level, whereas slope length and soil erodibility ranked lowest. Energy interception and soil erodibility were shown by parameter behavior analysis to behave in a linear fashion with respect to soil erosion hazard, whereas rainfall energy, slope steepness, and slope length exhibit non-linear behavior. When SLEMSA input parameters and results were compared to alternative methods of soil erosion assessment, such as drainage density and drainage texture, the model provided more spatially explicit information using 30 meter grid cells. Results of this study indicate that more accurate soil erosion estimates can be made when: (1) higher resolution digital elevation models are used; (2) data from improved precipitation station network are available, and; (3) greater investment in rainfall energy research.

    This study applied artificial intelligence to help nurses address problems and receive instructions through information technology. Nurses make diagnoses according to professional knowledge, clinical experience, and even instinct. Without comprehensive knowledge and thinking, diagnostic accuracy can be compromised and decisions may be delayed. We used a back-propagation neural network and other tools for data mining and statistical analysis. We further compared the prediction accuracy of the previous methods with an adaptive-network-based fuzzy inference system and the back-propagation neural network, identifying differences in the questions and in nurse satisfaction levels before and after using the nursing information system. This study investigated the use of artificial intelligence to generate nursing diagnoses. The percentage of agreement between diagnoses suggested by the information system and those made by nurses was as much as 87 percent. When patients are hospitalized, we can calculate the probability of various nursing diagnoses based on certain characteristics. PMID:26021669

    Dixon, Brent; Hanson, Duane; Matthern, Gretchen

    2003-02-27

    A number of broad perspective technology roadmaps have been developed in the last few years as tools for coordinating nation-wide research in targeted areas. These roadmaps share a common characteristic of coalescing the associated stakeholder groups into a special-interest community that is willing to work cooperatively in achieving the roadmap goals. These communities are key to roadmap implementation as they provide the collaborative energy necessary to obtain the political support and funding required for identified science and technology development efforts. This paper discusses the relationship between roadmaps and special-interest communities, using the recently drafted Department of Energy's Long-Term Stewardship Science and Technology Roadmap as a case study. Specific aspects this roadmap's design facilitated the development of a long-term stewardship community while specific realities during roadmap development impacted the realization of the design.

  7. Irrigation technology choices under hydrologic uncertainty: A case study from Maipo River Basin, Chile

    NASA Astrophysics Data System (ADS)

    Cai, Ximing; Rosegrant, Mark W.

    2004-04-01

    The effect of hydrologic uncertainty on field irrigation technology (FIT) choices is studied within this paper. A two-stage stochastic programming model (SPM) is developed to incorporate hydrologic uncertainties related to both water requirements and water availability through a probabilistic scenario-based approach. The SPM can provide a mechanism with which model solutions can be adjusted to account for variations in water availability and water requirements. Moreover, the two-stage decision process is combined with risk aversion analysis in field irrigation choices, which helps balance the risk of profit loss in dry years and the risk of excess capital cost in wet years. The model can be used to generate decision information to individual farmers or farmer associations, regarding long-term field irrigation technology choices and crop pattern planning and short-term water allocation among crops under specific hydrologic scenarios. The model is applied to an irrigation district in the Maipo River Basin, Chile. It is found that higher levels of FIT are more profitable for higher-valued crops and decisions on FIT choices for low-valued crops are less sensitive to hydrologic uncertainties. The annualized capital cost per hectare in the district should be within in range of US$105-130, which is a range for tradeoff analysis between maximizing the expected profit and minimizing the risk of profit loss under drought conditions.

    2012-01-01

    The ability to conduct genome-wide association studies (GWAS) has enabled new exploration of how genetic variations contribute to health and disease etiology. However, historically GWAS have been limited by inadequate sample size due to associated costs for genotyping and phenotyping of study subjects. This has prompted several academic medical centers to form ā€œbiobanksā€ where biospecimens linked to personal health information, typically in electronic health records (EHRs), are collected and stored on large number of subjects. This provides tremendous opportunities to discover novel genotype-phenotype associations and foster hypothesis generation. In this work, we study how emerging Semantic Web technologies can be applied in conjunction with clinical and genotype data stored at the Mayo Clinic Biobank to mine the phenotype data for genetic associations. In particular, we demonstrate the role of using Resource Description Framework (RDF) for representing EHR diagnoses and procedure data, and enable federated querying via standardized Web protocols to identify subjects genotyped with Type 2 Diabetes for discovering gene-disease associations. Our study highlights the potential of Web-scale data federation techniques to execute complex queries. PMID:23304343

    Research continues to investigate barriers to managing occupational health and safety behaviors among the workforce. Recent literature argues that (1) there is a lack of consistent, multilevel communication and application of health and safety practices, and (2) social scientific methods are absent when determining how to manage injury prevention in the workplace. In response, the current study developed and tested a multilevel intervention case study at two industrial mineral mines to help managers and workers communicate about and reduce respirable silica dust exposures at their mine sites. A dust assessment technology, the Helmet-CAM, was used to identify and encourage communication about potential problem areas and tasks on site that contributed to elevated exposures. The intervention involved pre- and post-assessment field visits, four weeks apart that included multiple forms of data collection from workers and managers. Results revealed that mine management can utilize dust assessment technology as a risk communication tool to prompt and communicate about healthier behaviors with their workforce. Additionally, when workers were debriefed with the Helmet-CAM data through the device software, the dust exposure data can help improve the knowledge and awareness of workers, empowering them to change subtle behaviors that could reduce future elevated exposures to respirable silica dust. This case study demonstrates that incorporating social scientific methods into the application of health and safety management strategies, such as behavioral modification and technology integration, can leverage managersā€™ communication practices with workers, subsequently improving health and safety behaviors.

  14. Technology Transfer Challenges: A Case Study of User-Centered Design in NASA's Systems Engineering Culture

    2009-01-01

    The Upper Stage (US) section of the National Aeronautics and Space Administration's (NASA) Ares I rocket will require internal access platforms for maintenance tasks performed by humans inside the vehicle. Tasks will occur during expensive critical path operations at Kennedy Space Center (KSC) including vehicle stacking and launch preparation activities. Platforms must be translated through a small human access hatch, installed in an enclosed worksite environment, support the weight of ground operators and be removed before flight - and their design must minimize additional vehicle mass at attachment points. This paper describes the application of a user-centered conceptual design process and the unique challenges encountered within NASA's systems engineering culture focused on requirements and "heritage hardware". The NASA design team at Marshall Space Flight Center (MSFC) initiated the user-centered design process by studying heritage internal access kits and proposing new design concepts during brainstorming sessions. Simultaneously, they partnered with the Technology Transfer/Innovative Partnerships Program to research inflatable structures and dynamic scaffolding solutions that could enable ground operator access. While this creative, technology-oriented exploration was encouraged by upper management, some design stakeholders consistently opposed ideas utilizing novel, untested equipment. Subsequent collaboration with an engineering consulting firm improved the technical credibility of several options, however, there was continued resistance from team members focused on meeting system requirements with pre-certified hardware. After a six-month idea-generating phase, an intensive six-week effort produced viable design concepts that justified additional vehicle mass while optimizing the human factors of platform installation and use. Although these selected final concepts closely resemble heritage internal access platforms, challenges from the application of the user-centered process provided valuable lessons for improving future collaborative conceptual design efforts.

  15. Technology Solutions Case Study: Combustion Safety for Appliances Using Indoor Air

    SciTech Connect

    2014-05-01

    This case study describes how to assess and carry out the combustion safety procedures for appliances and heating equipment that uses indoor air for combustion in low-rise residential buildings. Only appliances installed in the living space, or in an area freely communicating with the living space, vented alone or in tandem with another appliance are considered here. This document is for inspectors, auditors, and technicians working in homes where energy upgrades are being conducted whether or not air infiltration control is included in the package of measures being applied. In the indoor combustion air case, guidelines summarized here are based on language provided in several of the codes to establish minimum requirements for the space using simplified prescriptive measures. In addition, building performance testing procedures are provided by testing agencies. The codes in combination with the test procedures offer comprehensive combustion safety coverage to address safety concerns, allowing inexperienced residential energy retrofit inspectors to effectively address combustion safety issues and allow energy retrofits to proceed.

  16. A case study of the change process of integrating technology into an elementary science methods course from 1997 to 2003

    NASA Astrophysics Data System (ADS)

    Hsu, Pi-Sui

    The purpose of this qualitative case study was to provide a detailed description of the change process of technology integration into a science methods course, SCIED 458, as well as to interpret and analyze essential issues involved in the change process and examine how these factors influenced the change process. This study undertook qualitative research that employed case study research design. In-depth interviewing and review of the documents were two major data collection methods in this study. Participants included the three key faculty members in the science education program, a former graduate student who participated in writing the Link-to-Learn grant proposal, a former graduate student who taught SCIED 458, and two current graduate students who were teaching SCIED 458. A number of data analysis strategies were used in this study; these strategies included (1) coding for different periods of time and project categories and roles of people, (2) identifying themes, trends and coding for patterns, (3) reducing the data for analysis of trends and synthesizing and summarizing the data, and (4) integrating the data into one analytical framework. The findings indicated that this change process had evolved through the stages of adoption and diffusion, implementation, and institutionalization and a number of strategies facilitated the changes in individual stages, including the formation of a leadership team in the early stages, gradual adoption of technology tools, use of powerful pedagogy and methodology, the formation of a research community, and separation of technology training and subject teaching. The findings also indicated the essential factors and systems that interacted with each other and sustained the change process; these included a transformational shared leadership team, the formation of a learning and research community, reduced resistance of the elementary prospective teachers to technology, availability of university resources, involvement of the local school districts, support of the state department of education, recognition of the professional organizations, creation of partnerships with software companies, and technology advancements in society. A framework for integrating technology was presented to assist school reformers and instructional designers in initiating, implementing, and sustaining the changes due to technology integration in a systemic manner.

  17. Enhancement of Cognitive Processing by Multiple Sclerosis Patients Using Liquid Cooling Technology: A Case Study

    Montgomery, Leslie D.; Montgomery, Richard W.; Ku, Yu-Tsuan; Luna, Bernadette (Technical Monitor)

    1997-01-01

    Cognitive dysfunction is a common symptom in patients with multiple sclerosis (MS). This can have a significant impact on the quality of life of both the patient and of their primary care giver. This case study explores the possibility that liquid cooling therapy may be used to enhance the cognitive processing of MS patients in the same way that it provides temporary relief of some physical impairment. Two MS patients were presented a series of pattern discrimination tasks before and after being cooled with a liquid cooling garment for a one hour period. The subject whose ear temperature was reduced during cooling showed greater electroencephalographic (EEG) activity and scored much better on the task after cooling. The patient whose ear temperature was unaffected by cooling showed less EEG activity and degraded performance after the one hour cooling period.

  18. Technology Solutions Case Study: Guidance on Taped Insulating Sheathing Drainage Planes

    SciTech Connect

    2014-11-01

    The energy efficiency-based financial benefits of adding exterior insulation are well accepted by the building industry, and using exterior insulation as the drainage plane is the next logical step. This case study focuses on the field implementation of taped board insulation as the drainage plane in both new and retrofit residential applications, and provides information and recommendations for insulation contractors, general contractors, builders, remodelers, mechanical contractors, and homeowners. The order of work completed during home construction and retrofit improvements is important. Health and safety issues must be addressed first and are more important than durability issues, and durability issues are more important than saving energy. Three significant items are required to make taped insulating sheathing a simple, long term, and durable drainage plane: first, horizontal joints should be limited or eliminated wherever possible; where a horizontal joint exists, use superior materials; and, frequent installation inspection and regular trade training are required to maintain proper installation.

    2014-09-01

    Builder S.E. Volusia County Habitat for Humanity (SEVHFH) was interested in constructing a home to the new U.S. Department of Energy (DOE) Zero Energy Ready Home standards. SEVHFH partners with DOE team Building America Partnership for Improved Residential Construction on Habitat for Humanity homes and routinely builds to ENERGY STAR V3.1. The only modification to the design needed to comply with the Zero Energy Ready Home criteria was the interior duct requirement. Unwilling to incur the added costs of a foam roof deck or wall heights that exceed 8 ft to accommodate a fur-down chase, SEVHFH opted to build a fur-up or raised ceiling chase. This case study describes the project.

  20. Technology Solutions Case Study: Apartment Compartmentalization with an Aerosol-Based Sealing Process

    SciTech Connect

    2015-07-01

    Air sealing of building enclosures is a difficult and time-consuming process. Current methods in new construction require laborers to physically locate small and sometimes large holes in multiple assemblies and then manually seal each of them. This research study by Building America team Consortium for Advanced Residential Buildings demonstrated the automated air sealing and compartmentalization of buildings through the use of an aerosolized sealant developed by the Western Cooling Efficiency Center at University of California Davis. CARB demonstrated this new technology application in a multifamily building in Queens, NY. The effectiveness of the sealing process was evaluated by three methods: air leakage testing of overall apartment before and after sealing, point-source testing of individual leaks, and pressure measurements in the walls of the target apartment during sealing. Aerosolized sealing was successful by several measures in this study. Many individual leaks that are labor-intensive to address separately were well sealed by the aerosol particles. In addition, many diffuse leaks that are difficult to identify and treat were also sealed. The aerosol-based sealing process resulted in an average reduction of 71% in air leakage across three apartments and an average apartment airtightness of 0.08 CFM50/SF of enclosure area.

  1. Adopting Quality Assurance Technology in Customer-Vendor Relationships: A Case Study of How Interorganizational Relationships Influence the Process

    NASA Astrophysics Data System (ADS)

    Heeager, Lise Tordrup; TjĆørnehĆøj, Gitte

    Quality assurance technology is a formal control mechanism aiming at increasing the quality of the product exchanged between vendors and customers. Studies of the adoption of this technology in the field of system development rarely focus on the role of the relationship between the customer and vendor in the process. We have studied how the process of adopting quality assurance technology by a small Danish IT vendor developing pharmacy software for a customer in the public sector was influenced by the relationship with the customer. The case study showed that the adoption process was shaped to a high degree by the relationship and vice versa. The prior high level of trust and mutual knowledge helped the parties negotiate mutually feasible solutions throughout the adoption process. We thus advise enhancing trust-building processes to strengthen the relationships and to balance formal control and social control to increase the likelihood of a successful outcome of the adoption of quality assurance technology in a customer-vendor relationship.

  1. Technology Solutions Case Study: Improving the Field Performance of Natural Gas Furnaces

    SciTech Connect

    2013-11-01

    The objective of this project is to examine the impact that common installation practices and age-induced equipment degradation may have on the installed performance of natural gas furnaces, as measured by steady-state efficiency and AFUE. PARR identified twelve furnaces of various ages and efficiencies that were operating in residential homes in the Des Moines Iowa metropolitan area and worked with a local HVAC contractor to retrieve them and test them for steady-state efficiency and AFUE in the lab. Prior to removal, system airflow, static pressure, equipment temperature rise, and flue loss measurements were recorded for each furnace. After removal from the field the furnaces were transported to the Gas Technology Institute (GTI) laboratory, where PARR conducted steady-state efficiency and AFUE testing. The test results show that steady-state efficiency in the field was 6.4% lower than that measured for the same furnaces under standard conditions in the lab, which included tuning the furnace input and air flow rate. Comparing AFUE measured under ASHRAE standard conditions with the label value shows no reduction in efficiency for the furnaces in this study over their 15 to 24 years of operation when tuned to standard conditions. Further analysis of the data showed no significant correlation between efficiency change and the age or the rated efficiency of the furnace.

    Carter, Simon; Green, Judith; Thorogood, Nicki

    2013-01-01

    Using the electric toothbrush as an example, this article examines the growing acceptability of domestic health technologies that blur the traditional boundaries between health, aesthetics and consumption. By using empirical material from individual and household interviews about people's oral health practices, this research explores the relationships between an everyday artefact, its users and their environments. It investigates the ways in which oral health technologies do, or do not, become domesticated in the home environment. We conclude that the domestication of oral health technologies is not inevitable, with the electric toothbrush often becoming an ā€˜unstable object' in the domestic setting. PMID:24260016

  4. Innovative Technologies And Vadose Zone Treatment Of Chlorinated Volatile Organic Compounds - Case Study

    SciTech Connect

    NOONKESTER, JAY V.; NICHOLS, RALPH L.; DIXON, KENETH L.

    2005-08-02

    Over the last 10 years a mix of innovative and conventional characterization techniques has been used to assess the contamination of vadose zone sediments beneath the pilot-scale test facility known as TNX at the Savannah River Site (SRS) in South Carolina. Shallow soils and groundwater beneath the TNX facility are contaminated with chlorinated volatile organic compounds (CVOCs), trichloroethylene (TCE), carbon tetrachloride (CCl{sub 4}), perchloroethylene (PCE), and chloroform (CHCl{sub 3}). An interim pump and treat remediation system was placed in operation in 1996 to provide hydraulic containment of groundwater containing greater than 500 ug/L dissolved TCE. In 1994, a vadose zone study was initiated to determine the degree and extent of CVOC contamination above the contaminated groundwater. Headspace sampling and analysis, acoustic infrared spectroscopy, cone penetrometry, and vadose zone pumping tests were used to determine contaminant concentrations and physical properties related to soil vapor extraction. In 2001, soil vapor extraction (SVE), a presumptive remedy for CVOCs in soils similar to those present beneath TNX, was selected to treat the CVOC contamination. Cone Penetrometer Testing (CPT) with soil vapor sampling provided a detailed understanding of the subsurface geology and CVOC distribution which was essential for proper well design and placement. Twelve SVE wells were installed using direct push technology (DPT) and were tested to determine specific capacity and CVOC concentrations. This information was then used to develop a strategy for operating the SVE system. Based on the results of the baseline testing and previous studies, sets of 2 to 3 extraction wells will be treated using SVE at one month intervals. This will allow continuous operation of the SVE system and give individual wells up to 3 months for rebound between treatments. This method of operation is intended to maximize contaminant recovery from individual wells and reduce the overall capital investment and operating cost of the SVE system.

  5. Stroke patientsā€™ utilisation of extrinsic feedback from computer-based technology in the home: a multiple case study realistic evaluation

    PubMed Central

    2014-01-01

    Background Evidence indicates that postā€‰āˆ’ā€‰stroke rehabilitation improves function, independence and quality of life. A key aspect of rehabilitation is the provision of appropriate information and feedback to the learner. Advances in information and communications technology (ICT) have allowed for the development of various systems to complement stroke rehabilitation that could be used in the home setting. These systems may increase the provision of rehabilitation a stroke survivor receives and carries out, as well as providing a learning platform that facilitates long-term self-managed rehabilitation and behaviour change. This paper describes the application of an innovative evaluative methodology to explore the utilisation of feedback for post-stroke upper-limb rehabilitation in the home. Methods Using the principles of realistic evaluation, this study aimed to test and refine intervention theories by exploring the complex interactions of contexts, mechanisms and outcomes that arise from technology deployment in the home. Methods included focus groups followed by multi-method case studies (nā€‰=ā€‰5) before, during and after the use of computer-based equipment. Data were analysed in relation to the context-mechanism-outcome hypotheses case by case. This was followed by a synthesis of the findings to answer the question, ā€˜what works for whom and in what circumstances and respects?ā€™ Results Data analysis reveals that to achieve desired outcomes through the use of ICT, key elements of computer feedback, such as accuracy, measurability, rewarding feedback, adaptability, and knowledge of results feedback, are required to trigger the theory-driven mechanisms underpinning the intervention. In addition, the pre-existing context and the personal and environmental contexts, such as previous experience of service delivery, personal goals, trust in the technology, and social circumstances may also enable or constrain the underpinning theory-driven mechanisms. Conclusions Findings suggest that the theory-driven mechanisms underpinning the utilisation of feedback from computer-based technology for home-based upper-limb post-stroke rehabilitation are dependent on key elements of computer feedback and the personal and environmental context. The identification of these elements may therefore inform the development of technology; therapy education and the subsequent adoption of technology and a self-management paradigm; long-term self-managed rehabilitation; and importantly, improvements in the physical and psychosocial aspects of recovery.

    1998-12-01

    The purpose of this presentation is to enlighten the reader on the advancements that have been made in the field of biometrics technology as it relates to government and industrial-type applications. The term 'biometrics' is defined as, 'Any technology that uses electronically scanned graphical information for identification purposes.' Biometric technology was for a long time in the experimental stages, with many BETA test projects that were really not applicable to industrial markets. During the course of this presentation, we will show that biometrics applications do work, can develop positive returns on investment, but from a security standpoint have some major application problems that still need to be overcome. We will also address which biometric technologies have a better future in the security world than others.

    Chang, D P

    1998-01-01

    Outreach, training, technology transfer, and research are often treated as programmatically distinct activities. The interdisciplinary and applied aspects of the Superfund Basic Research Program offer an opportunity to explore different models. A case study is presented that describes a collaborative outreach effort that combines all of the above. It involves the University of California's Davis and Berkeley program projects, the University of California Systemwide Toxic Substances Research and Teaching Program, the U.S. Navy's civilian workforce at the former Mare Island Naval Shipyard, Vallejo, California (MINSY), a Department of Defense (DoD) Environmental Education Demonstration Grant program, and the Private Industry Council of Napa and Sonoma counties in California. The effort applied a Superfund-developed technology to a combined waste, radium and polychlorinated biphenyl contamination, stemming from a problematic removal action at an installation/restoration site at MINSY. The effort demonstrates that opportunities for similar collaborations are possible at DoD installations. PMID:9703494

  10. Contesting Technologies in the Networked Society: A Case Study of Hydraulic Fracturing and Shale Development

    NASA Astrophysics Data System (ADS)

    Hopke, Jill E.

    In this dissertation, I study the network structure and content of a transnational movement against hydraulic fracturing and shale development, Global Frackdown. I apply a relational perspective to the study of role of digital technologies in transnational political organizing. I examine the structure of the social movement through analysis of hyperlinking patterns and qualitative analysis of the content of the ties in one strand of the movement. I explicate three actor types: coordinator, broker, and hyper-local. This research intervenes in the paradigm that considers international actors as the key nodes to understanding transnational advocacy networks. I argue this focus on the international scale obscures the role of globally minded local groups in mediating global issues back to the hyper-local scale. While international NGOs play a coordinating role, local groups with a global worldview can connect transnational movements to the hyper-local scale by networking with groups that are too small to appear in a transnational network. I also examine the movement's messaging on the social media platform Twitter. Findings show that Global Frackdown tweeters engage in framing practices of: movement convergence and solidarity, declarative and targeted engagement, prefabricated messaging, and multilingual tweeting. The episodic, loosely-coordinated and often personalized, transnational framing practices of Global Frackdown tweeters support core organizers' goal of promoting the globalness of activism to ban fracking. Global Frackdown activists use Twitter as a tool to advance the movement and to bolster its moral authority, as well as to forge linkages between localized groups on a transnational scale. Lastly, I study the relative prominence of negative messaging about shale development in relation to pro-shale messaging on Twitter across five hashtags (#fracking, #globalfrackdown, #natgas, #shale, and #shalegas). I analyze the top actors tweeting using the #fracking hashtag and receiving mentions with the hashtag. Results show statistically significant differences in the sentiment about shale development across the five hashtags. Results also indicate that the discourse on the main contested hashtag #fracking is dominated by activists, both individual activists and organizations.

  11. Modeling cascading diffusion of new energy technologies: case study of residential solid oxide fuel cells in the US and internationally.

    Subsidy programs for new energy technologies are motivated by the experience curve: increased adoption of a technology leads to learning and economies of scale that lower costs. Geographic differences in fuel prices and climate lead to large variability in the economic performance of energy technologies. The notion of cascading diffusion is that regions with favorable economic conditions serve as the basis to build scale and reduce costs so that the technology becomes attractive in new regions. We develop a model of cascading diffusion and implement via a case study of residential solid oxide fuel cells (SOFCs) for combined heating and power. We consider diffusion paths within the U.S. and internationally. We construct market willingness-to-pay curves and estimate future manufacturing costs via an experience curve. Combining market and cost results, we find that for rapid cost reductions (learning rate = 25%), a modest public subsidy can make SOFC investment profitable for 20-160 million households. If cost reductions are slow however (learning rate = 15%), residential SOFCs may not become economically competitive. Due to higher energy prices in some countries, international diffusion is more favorable than domestic, mitigating much of the uncertainty in the learning rate. PMID:23815497

  20. Technology Solutions Case Study: Stud Walls with Continuous Exterior Insulation for Factory Built Housing

    SciTech Connect

    2014-01-01

    The Advanced Envelope Research effort will provide factory homebuilders with high performance, cost-effective alternative envelope designs. In the near term, these technologies will play a central role in meeting stringent energy code requirements. For manufactured homes, the thermal requirements, last updated by statute in 1994, will move up to the more rigorous IECC 2012 levels in 2013, the requirements of which are consistent with site built and modular housing. This places added urgency on identifying envelope technologies that the industry can implement in the short timeframe. The primary goal of this research is to develop wall designs that meet the thermal requirements based on 2012 IECC standards. Given the affordable nature of manufactured homes, impact on first cost is a major consideration in developing the new envelope technologies. This work is part of a four-phase, multi-year effort. Phase 1 identified seven envelope technologies and provided a preliminary assessment of three selected methods for building high performance wall systems. Phase 2 focused on the development of viable product designs, manufacturing strategies, addressing code and structural issues, and cost analysis of the three selected options. An industry advisory committee helped critique and select the most viable solution to move further in the research ā€” stud walls with continuous exterior insulation. Phase 3, the subject of the current report, focused on the design development of the selected wall concept and explored variations on the use of exterior foam insulation. The scope also included material selection, manufacturing and cost analysis, and prototyping and testing.

    These three single-case studies assessed the use of walker devices and microswitch technology for promoting ambulation behavior among persons with multiple disabilities. The walker devices were equipped with support and weight lifting features. The microswitch technology ensured that brief stimulation followed the participants' ambulation responses. The participants were two children (i.e., Study I and Study II) and one man (i.e., Study III) with poor ambulation performance. The ambulation efforts of the child in Study I involved regular steps, while those of the child in Study II involved pushing responses (i.e., he pushed himself forward with both feet while sitting on the walker's saddle). The man involved in Study III combined his poor ambulation performance with problem behavior, such as shouting or slapping his face. The results were positive for all three participants. The first two participants had a large increase in the number of steps/pushes performed during the ambulation events provided and in the percentages of those events that they completed independently. The third participant improved his ambulation performance as well as his general behavior (i.e., had a decline in problem behavior and an increase in indices of happiness). The wide-ranging implications of the results are discussed. PMID:23643772

  19. Integrating Multiple Subsurface Exploration Technologies in Slope Hydrogeologic Investigation: A Case Study in Taiwan

    NASA Astrophysics Data System (ADS)

    2009-04-01

    Taiwan is an island located at a tectonically active collision zone between the Eurasian Plate and the Pacific Plate. Also, the island is in the subtropical climate region with frequent typhoon events that are always accompanied by intense rainfalls within a short period of time. These seismic and climatic elements frequently trigger, directly or indirectly, natural disasters such as landslides on the island with casualties and property damages. Prompted by the urge for minimizing the detrimental effects of such natural disasters, Taiwan government has initiated and funded a series of investigations and studies aimed at better understanding the causes of the natural disasters that may lead to the formulation of more effective disaster contingency plans and possibly some forecasts system. The hydrogeology of a landslide site can help unveil the detention condition of storm water entering the aquifer system of the slope as well as its groundwater condition which, in turn, plays a critical role in slope stability. In this study, a hydrogeologic investigation employing a series of subsurface exploration technologies was conducted at an active landslide site in the vicinity of Hwa Yuan Village in northern Taiwan. The site, which covers an area of approximately 0.14 km2 (35 acres) and generally ranges between 25 to 36 degree in slope, was initially investigated with ground resistivity image profiling (RIP) and electrical logging in order to determine the lithology and possibly the water-bearing capacity of the geologic units beneath the slope surface. Subsequently, both acoustic and optical borehole loggings were then applied to identify potentially significant fracture features at depth and their hydrogeologic implications. In addition, flowmeter loggings and hydraulic packer tests were conducted to further characterize the hydrogeologic system of the site and quantitatively determine the hydraulic properties of major hydrogeologic units. According to the ground resistivity profiles combined with rock core data, the geologic units can be primarily categorized into colluvium and weathered rock at depths of 4-23 m and 23-80 m, respectively. An approximately 20 m shear zone at depths of 45-65 m was found based on the detection outcome of low electrical resistance. Also, according to the borehole electrical logging, the layer of sandstone was identified in the interval of 48-59 m and 68.5-74 m and showed low water-bearing capacity. In addition, the electrical logging identified the layer of shale was in the interval of 59-68.5 m, which possessed a high water-bearing capacity. The velocity profile along the borehole was obtained from the flowmeter logging. A relatively high velocity zone (1.36~2.23 m/min) was measured in the interval of sandstone and relatively low velocity zone (0.12~0.78 m/min) was measured in the interval of shale, which is similar to those found in electrical logging. Moreover, 198 discontinuity planes were identified from the borehole image logging. The orientations of all discontinuities were calculated and compiled to draw a stereographic projection diagram. Judging from the discontinuity clusters on the stereographic projection diagram, a plane failure may possibly occur based on Hoek and Brown's criteria. This is a good demonstration that slope failure geometry and type can be determined by stereographic projection diagram analysis. The borehole images also clearly showed the structures of discontinuities at depth. They not only helped to characterize the results of the above investigation technologies but also provided useful indication in selecting specific geologic intervals for packer tests. The packer tests were conducted and the intervals were isolated based on the results of borehole and flowmeter logging. They indicated that the hydraulic conductivities of the shale and sandstone intervals are respectively 1.37ƃ-10-8 m/sec and 2.68ƃ-10-5-3.76ƃ-10-5 m/sec, which are in good accordance with the hydraulic characteristics inferred by flowmeter logging. The aforementioned investigation results, including the geology units and water-bearing capacity categorized by RIP and electrical logging, velocity and hydraulic conductivity obtained from flowmeter logging and packer test, and discontinuity structures recorded by borehole image logging, were used to clarify the complexity of the subsurface environment and to establish the hydrogeologic conceptual model of the landslide site.

    OBJECTIVE: Due to their toxicity, diesel emissions have been submitted to progressively more restrictive regulations in developed countries. However, in Brazil, the implementation of the Cleaner Diesel Technologies policy (Euro IV standards for vehicles produced in 2009 and low-sulfur diesel with 50 ppm of sulfur) was postponed until 2012 without a comprehensive analysis of the effect of this delay on public health parameters. We aimed to evaluate the impact of the delay in implementing the Cleaner Diesel Technologies policy on health indicators and monetary health costs in Brazil. METHODS: The primary estimator of exposure to air pollution was the concentration of ambient fine particulate matter (particles with aerodynamic diameters <2.5 Āµm, [PM2.5]). This parameter was measured daily in six Brazilian metropolitan areas during 2007-2008. We calculated 1) the projected reduction in the PM2.5 that would have been achieved if the Euro IV standards had been implemented in 2009 and 2) the expected reduction after implementation in 2012. The difference between these two time curves was transformed into health outcomes using previous dose-response curves. The economic valuation was performed based on the DALY (disability-adjusted life years) method. RESULTS: The delay in implementing the Cleaner Diesel Technologies policy will result in an estimated excess of 13,984 deaths up to 2040. Health expenditures are projected to be increased by nearly US$ 11.5 billion for the same period. CONCLUSIONS: The present results indicate that a significant health burden will occur because of the postponement in implementing the Cleaner Diesel Technologies policy. These results also reinforce the concept that health effects must be considered when revising fuel and emission policies. PMID:22760904

    The purpose of the NASA funded project, ‘Utilizing 3 Dimensional Data Views to Access Data and Discover Relationships Between Multiple Heterogeneous Data Sets Along the A-Train Tracks’ (Kempler, PI, NASA ROSES NNH07ZDA001N ACCESS Proposal) was to employ the latest 3 dimensional visualization technology to explore and provide direct data access to heterogeneous A-Train datasets, ‘operationally’, along, and on either side of the A-Train tracks. Google Earth (tm) provides the foundation for organizing, visualizing, publishing, and synergizing Earth science data in virtual 3 dimensions, for this project. Successful integration of Google Earth (tm) into the A-Train Data Depot (ATDD), resulted in: a) visualizing two-, three- and four-dimensional Earth science data on Google Earth (tm); b) visualizing and synergizing analyzed results derived from the Giovanni online analysis system; and c) visualizing results derived from other standard web services (e.g. OGC WMS). These implementations produce KMZ files that can be opened and visualized via a Google Earth (tm). Integrating A-Train data on Google Earth (tm) through ATDD (http://disc.gsfc.nasa.gov/atdd) affords users the ability to more efficiently discover, access, manipulate and analyze A-Train atmospheric data. The integration of Google Earth (tm) into the ATDD came with anticipated and unanticipated challenges, and solutions, insulated far beneath the easily obtainable ATDD Google Earth (tm) images and data downloads. In addition, some components of integration went rather smoothly. This presentation will discuss the challenges and non-challenges encountered and innovative solutions implemented to enable displaying NASA vertical and horizontal Earth science data within Google Earth (tm) technology. Findings discussed, include: - Interoperability between ATDD and Google Earth (tm) - Required enhancements to existing systems - Reuse of infused technology - Making the total greater than the some of the parts It is hoped that lessons learned and presented can be directly applied or extrapolated to better understanding and overcoming information technology infusion roadblocks.

    The aim of this paper is to compare different end-of-life tire (ELT) treatment technologies in China from an environmental and economic perspective. Four treatment technologies were evaluated: ambient grinding, devulcanization, pyrolysis and illegal tire oil extraction. Life cycle assessment (LCA) was applied to evaluate the potential environmental impact of each treatment based on the Eco-indicator 99 (Hierarchist approach) method provided by GaBi 4 software. The final result shows that pyrolysis represents the environmentally benign option while illegal tire oil extraction caused the worst damages. For the three legal treatments, although high credit was obtained when considering avoided impacts from recycled materials and energy, they have great impact as to respiratory effects (inorganic) dominantly contributed by energy production stage, which implies that the emphasis on environmental policies related to ELT treatment should shift from the control of emissions from treatment process to the reduction of energy consumption. A simplified comparison of net benefits and total impacts shows that the most eco-effective ELT treatment technology is pyrolysis, followed by dynamic devulcanization and ambient grinding. The illegal tire oil extraction, however, must be prohibited immediately because of its highest environmental pollution and lowest net benefit. PMID:20615682

  6. Enhancement of Cognitive Processing by Multiple Sclerosis Patients Using Liquid Cooling Technology: A Case Study

    Recent neuropsychological studies demonstrate that cognitive dysfunction is a common symptom in patients with multiple sclerosis. In many cases the presence of cognitive impairment affects the patient's daily activities to a greater extent than would be found due to their physical disability alone. Cognitive dysfunction can have a significant impact on the quality of life of both the patient and that of their primary caregiver. Two cognitively impaired male MS patients were given a visual discrimination task before and after a one hour cooling period. The subjects were presented a series of either red or blue circles or triangles. One of these combinations, or one fourth of the stimuli, was designated as the "target" presentation. EEG was recorded from 20 scalp electrodes using a Tracor Northern 7500 EEG/ERP system. Oral and ear temperatures were obtained and recorded manually every five minutes during the one hour cooling period. The EEG ERP signatures from each series of stimuli were analyzed in the energy density domain to determine the locus of neural activity at each EEG sampling time. The first subject's ear temperature did not decrease during the cooling period. It was actually elevated approximately 0.05 C by the end of the cooling period compared to his mean of control period value. In turn, Subject One's discrimination performance and cortical energy remained essentially the same after body cooling. In contrast, Subject Two's ear temperature decreased approx. 0.8 C during his cooling period. Subject Two's ERROR score decreased from 12 during the precooling control period to 2 after cooling. His ENERGY value increased approximately 300%, from a precooling value of approximately 200 to a postcooling value of nearly 600. These findings might be interpreted by the following three-part hypothesis: (1) the general cognitive impairment of MS patients may be a result of low or unfocused metabolic energy conversion in the cortex; (2) such differences show up most strongly in reduced energy in the occipital region during the initial processing of the precooling period visual stimulus which may indicate impaired early visual processing; and (3) increased postcooling activation in the le ft angular gyrus may result in enhanced higher-level reasoning related to processing visual task information. By this hypothesis the superior performance of Subject Two following body cooling may be a result of increased neural activation in his early visual recognition and processing centers.

  12. Information and communication technology in disease surveillance, India: a case study

    PubMed Central

    2010-01-01

    India has made appreciable progress and continues to demonstrate a strong commitment for establishing and operating a disease surveillance programme responsive to the requirements of the International Health Regulations (IHR[2005]). Within five years of its launch, India has effectively used modern information and communication technology for collection, storage, transmission and management of data related to disease surveillance and effective response. Terrestrial and/or satellite based linkages are being established within all states, districts, state-run medical colleges, infectious disease hospitals, and public health laboratories. This network enables speedy data transfer, video conferencing, training and e-learning for outbreaks and programme monitoring. A 24x7 call centre is in operation to receive disease alerts. To complement these efforts, a media scanning and verification cell functions to receive reports of early warning signals. During the 2009 H1N1 outbreak, the usefulness of the information and communication technology (ICT) network was well appreciated. India is using ICT as part of its Integrated Disease Surveillance Project (IDSP) to help overcome the challenges in further expansion in hard-to-reach populations, to increase the involvement of the private sector, and to increase the use of other modes of communication like e-mail and voicemail.

Astronomy is also investigated in the area of Education, based mainly on theoretical aspects of educational socio-interacionist of Lev Semenovich Vygotsky (Vygotsky, 1991, 2008 and 2012, p. 103-117) and socio-historical cultural of Paulo Reglus Neves Freire (1979, 1982 and 1996), but when necessary and still keeping the field of constructivism, properly taking advantage of the interactionism and transdisciplinarity of Jean William Fritz Piaget (1983). Concerning Distance Education [DE], it is noted significant growth at the graduate and postgraduate courses. New challenges arise, with the establishment of an increasingly accustomed to Information and Communication Technologies [ICT] and the teaching methodologies to be used and developed, with Astronomy becoming an important instrument in the teaching-learning process associated technologies. Using the methodology of action research, we proceeded with a case study involving 26 students of the discipline of Astronomy Topics applied to Education, between November 1 and December 17, 2012, of the postgraduation courses in Distance Education at the Universidade Cruzeiro do Sul [Southern Cross University]. The results obtained permit statistical surveys therefore quantitative, but also qualitative information about the teaching-learning Astronomy by DE. Analyses of performance and progress of each student and set permit a finding interaction among those involved in the mediation of the teacher-tutor who, in turn, as a researcher also went through changes to processes meet also inserted in the role of agent or actor, while also influences and is influenced.

    In this project, Building America team IBACOS worked with a builder of single- and multifamily homes in southwestern Pennsylvania (climate zone 5) to understand its methods of successfully using polyethylene sheeting over aggregate as a capillary break beneath the slab in new construction. This builderā€™s homes vary in terms of whether they have crawlspaces or basements. However, in both cases, the strategy protects the home from water intrusion via capillary action (e.g., water wicking into cracks and spaces in the slab), thereby helping to preserve the durability of the home.

  15. Technology Solutions Case Study: Optimizing Hydronic System Performance in Residential Applications, Ithaca, New York

    SciTech Connect

    2013-11-01

    Condensing boiler technology has been around for many years and has proven to be a durable, reliable method of heating. Based on previous research efforts, however, it is apparent that these types of systems are not designed and installed to achieve maximum efficiency. For example, in order to protect their equipment in the field, manufacturers of low-mass condensing boilers typically recommend design strategies and components that ensure steady, high flow rates through the heat exchangers, such as primary-secondary piping, which ultimately result in decreased efficiency. There is also a significant lack of information for contractors on how to configure these systems to optimize overall efficiency. In response to these findings, researchers from Building America team Consortium for Advanced Residential Buildings worked with industry partners to develop hydronic system designs that would address these issues and result in higher overall system efficiencies and improved response times.

    This paper presents results of a Capital Equipment Management Plan undertaken at a major acute hospital in Australia. By classifying existing equipment using a threshold replacement value into Major and Minor items, detailed planning information was collected for 527 items of Major equipment representing 80% of the hospital's total equipment stock. A number of meaningful views of this significant asset base are presented, and a prioritisation method used to provide recommendations for future equipment replacement and acquisition for a 5 year planning period. The survey work to identify and document actual equipment items provides a convincing argument for the funding levels required for capital equipment replacement and acquisition, and evidence for the extent of technology reliance in modern health care facilities.

    Building science research supports installing exterior (soil side) foundation insulation as the optimal method to enhance the hygrothermal performance of new homes. With exterior foundation insulation, water management strategies are maximized while insulating the basement space and ensuring a more even temperature at the foundation wall. This project describes an innovative, minimally invasive foundation insulation upgrade technique on an existing home that uses hydrovac excavation technology combined with a liquid insulating foam. Cost savings over the traditional excavation process ranged from 23% to 50%. The excavationless process could result in even greater savings since replacement of building structures, exterior features, utility meters, and landscaping would be minimal or non-existent in an excavationless process.

    2007-12-01

    The Advancing Geospatial Skills in Science and Social Sciences (AGSSS) program, funded by NSF, provides middle and high school teacher-partners with access to graduate student scientists for classroom collaboration and curriculum adaptation to incorporate and advance skills in spatial thinking. AGSSS Fellows aid in the delivery of geospatially-enhanced activities utilizing technology such as geographic information systems, remote sensing, and virtual globes. The partnership also provides advanced professional development for both participating teachers and fellows. The AGSSS program is mutually beneficial to all parties involved. This successful collaboration of scientists, teachers, and students results in greater understanding and enthusiasm for the use of spatial thinking strategies and geospatial technologies. In addition, the partnership produces measurable improvements in student efficacy and attitudes toward processes of spatial thinking. The teacher partner training and classroom resources provided by AGSSS will continue the integration of geospatial activities into the curriculum after the project concludes. Time and resources are the main costs in implementing this partnership. Graduate fellows invest considerable time and energy, outside of academic responsibilities, to develop materials for the classroom. Fellows are required to be available during K-12 school hours, which necessitates forethought in scheduling other graduate duties. However, the benefits far outweigh the costs. Graduate fellows gain experience in working in classrooms. In exchange, students gain exposure to working scientists and their research. This affords graduate fellows the opportunity to hone their communication skills, and specifically allows them to address the issue of translating technical information for a novice audience. Teacher-partners and students benefit by having scientific expertise readily available. In summation, these experiences result in changes in teacher/student perceptions of science and scientists. Evidence of the aforementioned changes are provided through external evaluation and results obtained from several assessment tools. The program also utilizes an internal evaluator to monitor participants thoughts and opinions on the previous years' collaboration. Additionally, graduate fellows maintain a reflective journal to provide insight into experiences occurring both in-class and among peers. Finally, student surveys administered prior to and concluding the academic year assess changes in student attitudes and self-perception of spatial thinking skills.

  3. Life Cycle Assessment Projection of Photovoltaic Cells: A Case Study on Energy Demand of Quantum Wire Based Photovoltaic Technology Research

    NASA Astrophysics Data System (ADS)

    Mukherjee, Shilpi

    With increasing clean-energy demand, photovoltaic (PV) technologies have gained attention as potential long-term alternative to fossil fuel energy. However, PV research and manufacture still utilize fossil fuel-powered grid electricity. With continuous enhancement of solar conversion efficiency, it is imperative to assess whether overall life cycle efficiency is also being enhanced. Many new-material PV technologies are still in their research phase, and life cycle analyses of these technologies have not yet been performed. For best results, grid dependency must be minimized for PV research, and this can be accomplished by an analytical instrument called Life Cycle Assessment (LCA). LCA is the study of environmental impacts of a product throughout its life cycle. While there are some non-recoverable costs of research, energy is precious, and the PV research community should be aware of its energy consumption. LCA can help identify options for energy conservation through process optimization. A case study was conducted on the energy demand of a test-bed emerging PV technology using life cycle assessment methodology. The test-bed system chosen for this study was a new-material PV cell. The objective was to quantify the total energy demand for the research phase of the test-bed solar cell's life cycle. The objective was accomplished by collecting primary data on energy consumption for each process in the development of this solar cell. It was found that 937 kWh of energy was consumed for performing research on a single sample of the solar cell. For comparison, this energy consumption is 83% of Arkansas's average monthly residential electricity consumption. Life cycle inventory analysis showed that heating, ventilation, and air conditioning consumed the bulk of the energy of research. It is to be noted that the processes studied as part of the solar cell test-bed system are representative of a research process only. Life cycle thinking can identify energy hot-spots and help a new lab be set up in a more energy-efficient way. Proactive action based on the results can lead to higher energy return on investment, making emerging PV technologies truly energy-competitive.

    This paper addresses the issue of integrating the C Language Integrated Production System (CLIPS) into distributed data acquisition environments. In particular, it presents preliminary results of some ongoing software development projects aimed at exploiting CLIPS technology in the new mission control center (MCC) being built at NASA Johnson Space Center. One interesting aspect of the control center is its distributed architecture; it consists of networked workstations which acquire and share data through the NASA/JSC-developed information sharing protocol (ISP). This paper outlines some approaches taken to integrate CLIPS and ISP in order to permit the development of intelligent data analysis applications which can be used in the MCC. Three approaches to CLIPS/IPS integration are discussed. The initial approach involves clearly separating CLIPS from ISP using user-defined functions for gathering and sending data to and from a local storage buffer. Memory and performance drawbacks of this design are summarized. The second approach involves taking full advantage of CLIPS and the CLIPS Object-Oriented Language (COOL) by using objects to directly transmit data and state changes from ISP to COOL. Any changes within the object slots eliminate the need for both a data structure and external function call thus taking advantage of the object matching capabilities within CLIPS 6.0. The final approach is to treat CLIPS and ISP as peer toolkits. Neither is embedded in the other; rather the application interweaves calls to each directly in the application source code.

  5. Health economic evaluation in Japan: a case study of one aspect of health technology assessment.

    PubMed

    Oliver, Adam

    2003-02-01

    There is a burgeoning literature in health economic evaluation, with this form of analysis becoming increasingly influential at the health policy making level in a number of countries. However, a search of the literature reveals that in Japan, the world's second largest health care market, very little health economic evaluation has been undertaken. The main reason for the lack of interest in economic evaluation is that the fee-for-service and strict price regulation that characterises the system of health care financing in Japan is not conducive to this form of analysis. Moreover, the government and many researchers are satisfied that the current organisation of health care has given long life and low infant mortality at low cost. Even if it is accepted that low health care costs and good health prevail in Japan, slower economic growth rates, an ageing population and the development of new medical technologies will place increasing pressure on health care resources and will necessitate a more rational use of these resources. Good economic evaluation, by weighing benefits against costs, has an important role to play. PMID:12543532

    Safe clinical practice in implant dentistry requires an accurate investigation of the availability of bone for implant placement and the avoidance of critical anatomical structures. Modern imaging techniques using computed tomography (CT) and cone beam computed tomography (CBCT) provide the clinician with the required information. The imaging thus obtained provides accurate representation of the height, width and length of the available bone. In addition, whenever adequate radiation dose is used, accurate information about the bone density in Hounsfield units can be obtained. Important spatial information regarding the orientation of the ridges and the relationship to the proposed prosthetic reconstruction can be obtained with the aid of radiopaque templates during the acquisition of CT scan data. Modern software also provides the facility to decide interactively upon the positioning of the implants and is able to relate this to a stereolithographic model constructed from the imaging data. A surgical guide for the accurate positioning of the implants can be constructed. The construction of screw retained prostheses is fraught with difficulties regarding the accuracy of the construction. Accurate fit of the prosthesis is difficult to obtain due to the inherent errors in impression taking, component discrepancies, investing and casting inaccuracies. CAD/CAM technology eliminates the inaccuracies involved with the investing and casting of superstructures. PMID:23726493

    2007-07-01

    The regulatory release of sites and facilities (property) for restricted or unrestricted use has evolved beyond prescribed levels to model-derived dose and risk based limits. Dose models for deriving corresponding soil radionuclide concentration guidelines are necessarily simplified representations of complex processes. It is not practical to obtain data to fully or accurately characterize transport and exposure pathway processes. Similarly, it is not possible to predict future conditions with certainty absent durable land use restrictions. To compensate for the shortage of comprehensive characterization data and site specific inputs to describe the projected 'as-left' contaminated zone, conservative default values are used to derive acceptance criteria. The result is overly conservative criteria. Furthermore, implementation of a remediation plan and subsequent final surveys to show compliance with the conservative criteria often result in excessive remediation due to the large uncertainty. During a recent decommissioning project of a site contaminated with thorium, a unique approach to dose modeling and remedial action design was implemented to effectively manage end-point uncertainty. The approach used a dynamic feedback dose model and soil segregation technology to characterize impacted material with precision and accuracy not possible with static control approaches. Utilizing the remedial action goal 'over excavation' and subsequent auto-segregation of excavated material for refill, the end-state (as-left conditions of the refilled excavation) RESRAD input parameters were re-entered to assess the final dose. The segregation process produced separate below and above criteria material stockpiles whose volumes were optimized for maximum refill and minimum waste. The below criteria material was returned to the excavation without further analysis, while the above criteria material was packaged for offsite disposal. Using the activity concentration data recorded by the segregation system and the as-left configuration of the refilled excavation, the end state model of the site was prepared with substantially reduced uncertainty. The major projected benefits of this approach are reviewed as well as the performance of the segregation system and lessons learned including: 1) Total, first-attempt data discovery brought about by simultaneously conducted characterization and final status surveys, 2) Lowered project costs stemming from efficient analysis and abstraction of impacted material and reduced offsite waste disposal volume, 3) Lowered project costs due to increased remediation/construction efficiency and decreased survey and radio-analytical expenses, and 4) Improving the decommissioning experience with new regulatory guidance.

  13. Attitudes of fertile and infertile woman towards new reproductive technologies: a case study of Lithuania

    PubMed Central

    2014-01-01

    Background This article analyzes several key issues in the debate: the acceptability of in vitro fertilization; regulation of assisted reproduction and the possibilities of reimbursement for assisted reproduction treatment in Lithuania. Method Two groups of respondents participated in the survey: fertile women and women with fertility disorders. 93 completed questionnaires from women with fertility problems and 146 from women with no fertility problems were analysed. Results Fertile respondents more frequently perceived the embryo as a human being (Fertile Individuals ā€“ 68.5%; Infertile Individuals ā€“ 35.5%; p < 0.05) and more frequently maintained that assisted reproduction treatment should be only partly reimbursed (Fertile Individuals ā€“ 71.3%; Infertile Individuals ā€“ 39.8%; p < 0.05). Respondents with fertility disorders more frequently thought that artificial insemination procedure could also be applied to unmarried couples (Fertile Individuals ā€“ 51.4%; Infertile Individuals ā€“ 76.3%; p < 0.05), and more frequently agreed that there should be no age limit for artificial insemination procedures (Fertile Individuals ā€“ 36.3%; Infertile Individuals ā€“ 67.7%; p < 0.05). The majority of respondents in both groups (Fertile Individuals ā€“ 77.4%; Infertile Individuals ā€“ 82.8%; p < 0.05) believed that donation of reproductive cells should be regulated by law. Fertile respondents more frequently considered that strict legal regulation was necessary in case of the number of transferred embryos (Fertile Individuals ā€“ 69.2%; Infertile Individuals ā€“ 39.8%; p < 0.05) and freezing of embryos (Fertile Individuals ā€“ 69.9%; Infertile Individuals ā€“ 57.0%; p < 0.05). Conclusion Fertile respondents were statistically more likely to believe that the IVF procedure should be applied only to married couples or women who had a regular partner, the age limit should be defined and the psychological assessment of the coupleā€™s relationship and their readiness for the IVF procedure was necessary. In contrast, infertile couples were statistically more likely than fertile respondents to maintain that the IVF procedure should be fully reimbursed by the state. Fertile respondents were statistically more likely to be categorical with respect to the number of embryos and the freezing of embryos. Meanwhile there is a statistically significant difference in opinions of infertile respondents who were in favour of stricter regulation on donation of reproductive cells. PMID:24684746

    Energy efficiency upgrades reduce heating and cooling loads on a house. With enough load reduction and if the HVAC system warrants replacement, the HVAC system is often upgraded with a more efficient, lower capacity system that meets the loads of the upgraded house. In this project, IBACOS studied when HVAC equipment is downsized and ducts are unaltered to determine conditions that could cause a supply air delivery problem and to evaluate the feasibility of modifying the duct systems using minimally invasive strategies to improve air distribution.

    PeaceHealth is a multistate, not-for-profit integrated delivery network that owns and operates five acute care hospitals, one critical access hospital, and twenty-five outpatient clinics. PeaceHealth employs approximately two hundred physicians and seventy allied health professionals; it has relationships with one thousand affiliated physicians. In 1990, PeaceHealth developed a set of strategic priorities for delivering seamless care across the continuum, and creating partnerships between caregivers and patient-consumers. A major component of these strategies was development and implementation of the technology, knowledge, organizational, and community infrastructures that would support delivering and using high-quality, timely information when and where it is needed for effective clinical, operational, and financial decision making. Executing this strategy has resulted in implementation of standard enterprisewide information systems, including a computer-based patient record system in inpatient and outpatient settings, tactical and strategic decision support systems, a well-developed intranet and access to the Internet, and a knowledgeable workforce that have enabled PeaceHealth to support and improve its services and business by bringing interactive information directly to patients, caregivers, managers, directors, and executives. This case study discusses the drivers behind the development of this strategy, specific components of the information management and information technology infrastructure, examples of the impact they have had on patients, caregivers, and the organization, and lessons learned.

    This paper presents the results of geophysical and archaeological investigations of the 18th century Moravian mission town at Gnadenhutten, Ohio. Magnetic gradiometer and ground penetrating radar surveys were conducted at the site to detect and interpret subsurface anomalies. Geophysical anomalies were assigned to typological classification through an analysis of anomaly attribute data. A selection of geophysical anomalies was investigated through core sampling and test unit excavation to assess anomaly interpretations and test a hypothesized layout of the built environment of the Gnadenhutten Mission. Aspects of 18th century Moravian culture and the research from contemporary Moravian mission sites were studied to infer a consistency in design in the physical and social landscapes of these communities. It is argued that the built environment of Moravian mission towns were based on a replicable model developed to promote internal communal control as well as to project an outward appearance of idyllic communitarianism and civility.

    IT governance is a set of organizational structures ensuring decision-making rights and responsibilities with regard to the organizationā€™s IT assets. This qualitative study was carried out to identify the IT governance domains in teaching hospitals affiliated to Iran University of Medical Sciences. There were 10 heads of IT departments and 10 hospital directors. Semi structured interviews used for data collection. To analyze the data content analysis was applied. All the interviewees (100%) believed that decisions upon hospital software needs could be made in a decentralized fashion by the IT department of the university. Most of the interviewees (90%) believed that there were policies for logistics and maintenance of networks, purchase and maintenance, standards and general policies in the direction of the policies of the ministry of health and medical education. About 80% of the interviewees believed that the current emphasis of the hospitalā€™s IT unit and the hospital management for outsourcing of services were in the format of specialized contracts and under supervision of the university Statistic and IT department. A hospital strategic committee is an official organizational group consisting of hospital executives, heads of IT and multiple functional areas and business units in a hospital.

    2013-02-01

    In conjunction with the New York State Energy Research and Development Authority (NYSERDA) and Proctor Engineering Group, Ltd. (PEG), the Consortium for Advanced Residential Buildings (CARB) evaluated the Concept 3ā„¢ replacement motors for residential furnaces in eight homes in Syracuse, NY. These brushless, permanent magnet (BPM) motors can use much less electricity than their PSC (permanent split capacitor) predecessors. This evaluation focuses on existing homes in the heating-dominated climate of upstate New York with the goals of characterizing field performance and cost-effectiveness. The results of this study are intended to be useful to home performance contractors, HVAC contractors, and home efficiency program stakeholders. Tests and monitoring was performed both before and after fan motors were replaced. Average fan power reductions were approximately 126 Watts during heating and 220 Watts during cooling operation. Over the course of entire heating and cooling seasons, these translated into average electric energy savings of 163 kWh, with average cost savings of $20 per year. Homes where the fan was used outside of heating and cooling mode saved an additional $42 per year on average. Results indicate that BPM replacement motors will be most cost-effective in HVAC systems with longer run times and relatively low duct static pressures. More dramatic savings are possible if occupants use the fan-only setting when there is no thermal load.

  16. Technology Solutions Case Study: Advanced Boiler Load Monitoring Controls, Chicago, Illinois

    SciTech Connect

    2014-09-01

    Most of Chicagoā€™s older multifamily housing stock is heated by centrally metered steam or hydronic systems. The cost of heat is typically absorbed into the ownerā€™s operating cost and is then passed to tenants. Central boilers typically have long service lifetimes; the incentive for retrofit system efficiency upgrades is greater than equipment replacement for the efficiency-minded owner. System improvements as the ā€œlow-hanging fruitā€ are familiar, from improved pipe insulation to aftermarket controls such as outdoor temperature reset (OTR) or lead/lag controllers for sites with multiple boilers. Beyond these initial system efficiency upgrades are an emerging class of Advanced Load Monitoring (ALM) aftermarket controllers that dynamically respond to the boiler load, with claims of 10% to 30% of fuel savings over a heating season. In this project, the Building America team Partnership for Advanced Residential Retrofit (PARR) installed and monitored an ALM aftermarket controller, the M2G from Greffen Systems, at two Chicago area multifamily buildings with existing OTR control. Results show that energy savings depend on the degree to which boilers are oversized for their load, represented by cycling rates. Also, savings vary over the heating season with cycling rates, with greater savings observed in shoulder months. Over the monitoring period, oversized boilers at one site showed reductions in cycling and energy consumption in line with prior laboratory studies, while less oversized boilers at another site showed muted savings.

    The correct choice and customization of an orthosis are crucial to obtain the best comfort and efficiency. This study explored the feasibility of a multivariate quantitative assessment of the functional efficiency of lower limb orthosis through a novel wearable system. Gait basographic parameters and energetic indexes were analysed during a Six-Minute Walking Test (6-MWT) through a cost-effective, non-invasive polygraph device, with a multichannel wireless transmission, that carried out electro-cardiograph (ECG); impedance-cardiograph (ICG); and lower-limb accelerations detection. Four subjects affected by Post-Polio Syndrome (PPS) were recruited. The wearable device and the semi-automatic post-processing software provided a novel set of objective data to assess the overall efficiency of the patient-orthosis system. Despite the small number of examined subjects, the results obtained with this new approach encourage the application of the method thus enlarging the dataset to validate this promising protocol and measuring system in supporting clinical decisions and out of a laboratory environment.

    2014-11-01

    The ARIES Collaborative, a U.S. Department of Energy Building America research team, partnered with NeighborWorks America affiliate Homeowners' Rehab Inc. (HRI) of Cambridge, Massachusetts, to study improvements to the central hydronic heating system in one of the nonprofit's housing developments. The heating controls in the three-building, 42-unit Columbia Cambridge Alliance for Spanish Tenants housing development were upgraded. Fuel use in the development was excessive compared to similar properties. A poorly insulated thermal envelope contributed to high energy bills, but adding wall insulation was not cost-effective or practical. The more cost-effective option was improving heating system efficiency, which faced several obstacles, including inflexible boiler controls and failed thermostatic radiator valves. Boiler controls were replaced with systems that offer temperature setbacks and one that controls heat based on apartment temperature in addition to outdoor temperature. Utility bill analysis shows that post-retrofit weather-normalized heating energy use was reduced by 10%-31% (average of 19%). Indoor temperature cutoff reduced boiler runtime (and therefore heating fuel consumption) by 28% in the one building in which it was implemented. Nearly all savings were obtained during night which had a lower indoor temperature cut off (68Ā°F) than day (73Ā° F). This implies that the outdoor reset curve was appropriately adjusted for this building for daytime operation. Nighttime setback of heating system supply water temperature had no discernable impact on boiler runtime or gas bills.

    The primary concern of this study was to examine if there are significant difference in teachers' perceptions and students' attitudes toward technology integrated into the science classroom based on their school group and grade level. In addition, this study also examined students' opinions toward technology as a tool of learning in the science classroom and to what extent students' attitudes toward technology and their perceptions of the classroom environment influence their intention to pursue technology. Four research questions were established to guide the data collection: (1) Is there any significant difference in teachers' perceptions toward technology based on their school group and grade level? (2) Is there any significant difference in students' attitudes toward technology based on their school group and grade level? (3) What are students' opinions about technology as a tool of learning in the science classroom and to what extent their attitudes toward technology and their perceptions of the classroom environment influence their intention to pursue technology? (4) What are the factors that affect technology integration into the science classroom? This study detected that most of the teachers from the traditional school have less intention in using technology than the modern school. In addition, traditional school students also view the method of using technology as interesting and fun. While most tenth-grade, eleventh-grade and twelfth-grade students planned to select technology as a tool to support their field in the university, this study found that students made this decision because they like and enjoy learning technology. Ironically, a majority of traditional school students in the twelfth-grade who are taking science as their major did not have any intentions at all to pursue technology majors in the university. Furthermore, the study also found that students, regardless of their school group and grade level differences, expected a more positive classroom environment climate during learning using technology. As composed to statistically significant differences between the modern school and traditional school that students' perceptions of their classroom environment climate during learning using technology has been found in which modern school students experience a more positive classroom climate than traditional school students.

    2016-05-01

    Integration of technology ( e.g. measuring with sensors, video measurement, and modeling) into secondary-school science teaching is a need globally recognized. A central issue of incorporating these technologies in teaching is how to turn manipulations of equipment and software into manipulations of ideas. Therefore, preparation for pre-service teachers to apply ICT tools should be combined with the issues of minds-on inquiring and meaning-making. From this perspective, we developed a course within the post-graduate teacher-education program in the Netherlands. During the course, pre-service teachers learnt not only to master ICT skills but also to design, teach, and evaluate an inquiry-based lesson in which the ICT tool was integrated. Besides three life sessions, teachers' learning scenario also consisted of individual tasks which teachers could carry out mostly in the school or at home with support materials and online assistance. We taught three iterations of the course within a design-research framework in 2013, 2014 and collected data on the teacher learning processes and outcomes. The analyses of these data from observation, interviews, questionnaires, and documents were to evaluate implementation of the course, then suggest for revisions of the course set-up, which was executed and then assessed again in a subsequent case study. Main outcomes of the three case studies can be summarized as follows: within a limited time (3 life sessions spread over 2-3 months), the heterogeneous groups of pre-service teachers achieved a reasonable level of competence regarding the use of ICT tools in inquiry-based lessons. The blended set-up with support materials, especially the Coach activities and the lesson-plan form for an ICT-integrated inquiry-based lesson, contributed to this result under the condition that the course participants really spent considerable time outside the life sessions. There was a need for more time for hands-on, in-group activities in life sessions and more detailed feedback on individual reports of pre-service teachers. The majority of the pre-service teachers were able to design a lesson plan aimed at a certain inquiry level with integration of ICT, but just a few could implement it faithfully in the classroom. There was still a considerable difference between intended inquiry activities and actual realized inquiry which parallels results from the literature for experienced teachers. The participants had to struggle with science --ICT conceptual issues as well as getting their students to focus on inquiry and concept learning in the classroom. Each evaluation guided iteration of the course resulted in better learning outcomes.

    2012-02-01

    The purpose of this case-study is to narrate a secondary science teacher's experience of his professional development (PD) education and training in innovative technologies (IT) in the context of engaging students in environmental research projects The sources from which the narrative is derived include (1) the science teacher's reflective reports during three summer institute programs and (2) the science teacher's reflective reports while subsequently engaging students in IT-embedded environmental research projects in his classroom. The science teacher's explanations for changes in students' perception of their IT fluency illuminate his personal narrative. The science teacher attributed his growth and significant changes in students' perceptions of their IT fluency to the following mechanisms: (a) a personal commitment to developing his own and his students' IT abilities in the context of doing environmental research projects, and (b) an increase in class time devoted to science education due to school-time scheduling policy. The study implies that immersive professional development opportunities have the potential to produce significant increases in students' perceptions of their IT fluency.

    This study examined the characteristics of 10 science, technology, engineering, and mathematics (STEM) focused high schools. A comparative case designed was used to identify key components of STEM school designs. Schools were selected from various regions across the United States. Data collected included websites, national statistics database, standardized test scores, interviews and published articles. Results from this study indicate that there is a variety of STEM high school programs designed to increase students' ability to pursue college degrees in STEM fields. The school mission statements influence the overall school design. Students at STEM schools must submit an application to be admitted to STEM high schools. Half of the STEM high schools used a lottery system to select students. STEM high schools have a higher population of black students and a lower population of white and Hispanic students than most schools in the United States. They serve about the same number of economically disadvantaged students. The academic programs at STEM high schools are more rigorous with electives focused on STEM content. In addition to coursework requirements, students must also complete internships and/or a capstone project. Teachers who teach in STEM schools are provided regularly scheduled professional development activities that focus on STEM content and pedagogy. Teachers provide leadership in the development and delivery of the professional development activities.

  11. Curriculum Materials as a Vehicle for Innovation: a case study of the Nuffield Design and Technology Project

    NASA Astrophysics Data System (ADS)

    Givens, Nick

    2000-01-01

    Prior to the advent of the National Curriculum in England and Wales, the production of teaching materials was an established vehicle for curriculum change. The Nuffield Design and Technology Project recently published extensive materials which enlarge upon the National Curriculum. This paper presents an investigation based on case studies of two teachers in separate schools, each using Nuffield publications with one of their classes. It explores: how Nuffield materials were selected and adapted by teachers; the resulting balances between in-house and Nuffield influence; and teachers' intuitive evaluations of the materials' impact. Both teachers `injected' similar Nuffield elements into existing schemes; they took ownership, exploiting the materials' flexibility. Both prescribed the mechanical/structural elements of the product, but allowed extensive pupil autonomy over aesthetic elements. Text books were initially underused. In describing the materials' impact, one teacher emphasised pupils' learning, the other the improved quality of his own experience. This paper suggests that even a little training may greatly enhance teachers' use of Nuffield resources.

    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 participating in a Design and Technology activity. The study linked that to the culture of the classroom where the technology period was considered by the students a period of "free time" to be spent mainly on the computer, playing educational games or engaged in short term, non-demanding projects.

    Many projects have been proposed to promote and demonstrate renewable energy technologies (RETs) in developing countries on the basis of their potential to reduce carbon emissions. However, no uniform methodology has been developed for evaluating RETs in terms of their future carbon emissions reduction potential. This study outlines a methodology for identifying RETs that have the potential for achieving large carbon emissions reductions in the future, while also meeting key criteria for commercialization and acceptability in developing countries. In addition, this study evaluates the connection between technology identification and the selection of projects that are designed to demonstrate technologies with a propensity for carbon emission reductions (e.g., Global Environmental Facility projects). Although this report applies the methodology to Mexico in a case study format, the methodology is broad based and could be applied to any developing country, as well as to other technologies. The methodology used in this report is composed of four steps: technology screening, technology identification, technology deployment scenarios, and estimates of carbon emissions reductions. The four technologies with the highest ranking in the technology identification process for the on-grid category were geothermal, biomass cogeneration, wind, and micro-/mini-hydro. Compressed natural gas (CNG) was the alternative that received the highest ranking for the transportation category.

  18. Adoption of new technology in sports medicine: case studies of the Gore-Tex prosthetic ligament and of thermal capsulorrhaphy.

    2011-01-01

    Evaluation of new technology in sports medicine is supposed to promote improvements in the care of patients. It is also supposed to prohibit technology that can harm patients. This evaluation process is not perfect and at times can promote technology that not only does not help patients but may harm them. Two examples of new sports medicine technology that were widely adopted but eventually abandoned are thermal capsulorrhaphy for treatment of shoulder instability and the Gore-Tex prosthetic ligament (W. L. Gore & Associates, Flagstaff, AZ) for patients with anterior cruciate ligament deficiency. On analysis of the quick adoption of these 2 failed procedures, certain recommendations are apparent for improvement of the evaluation process. There must be a sound rationale behind any new technology, basic science research into the theory of the medical technology, and demonstrated improvements in animal models and clinical studies that are prospective cohort studies or randomized controlled trials, and finally, there must be careful follow-up and postmarket surveillance.

  9. Applying the food technology neophobia scale in a developing country context. A case-study on processed matooke (cooking banana) flour in Central Uganda.

    PubMed

    De Steur, Hans; Odongo, Walter; Gellynck, Xavier

    2016-01-01

    The success of new food technologies largely depends on consumers' behavioral responses to the innovation. In Eastern Africa, and Uganda in particular, a technology to process matooke into flour has been introduced with limited success. We measure and apply the Food technology Neophobia Scale (FTNS) to this specific case. This technique has been increasingly used in consumer research to determine consumers' fear for foods produced by novel technologies. Although it has been successful in developed countries, the low number and limited scope of past studies underlines the need for testing its applicability in a developing country context. Data was collected from 209 matooke consumers from Central Uganda. In general, respondents are relatively neophobic towards the new technology, with an average FTNS score of 58.7%, which hampers the success of processed matooke flour. Besides socio-demographic indicators, 'risk perception', 'healthiness' and the 'necessity of technologies' were key factors that influenced consumer's preference of processed matooke flour. Benchmarking the findings against previous FTNS surveys allows to evaluate factor solutions, compare standardized FTNS scores and further lends support for the multidimensionality of the FTNS. Being the first application in a developing country context, this study provides a case for examining food technology neophobia for processed staple crops in various regions and cultures. Nevertheless, research is needed to replicate this method and evaluate the external validity of our findings. PMID:26463016

    2007-01-01

    The New Zealand Human Assisted Reproductive Technology (HART) Act became law in 2004. In this article, we provide a retrospective analysis of New Zealand case law from September 1990 to March 2004, leading up to the creation of the HART Act. We examine the new understandings of parenting (developed through the routine use of ART in New Zealand) which the case law attempted to test. We examine these concepts against the previous understandings of family enshrined in the pre-existing legislation, which formed the basis for judicial rulings in the various cases to which we refer. In conclusion, we provide a brief summary of the 2004 HART legislation and draw comparisons between the old and new legislative and bureaucratic frameworks that define and support New Zealand family structure. We suggest that a change in cultural backdrop is occurring from the traditional western ideology of the nuclear family towards the traditional Maori concept of family formation, which includes a well-accepted traditional practice of guardianship and a more open and extended family structure. This 'new' structure reflects the contemporary lived experience of family kinship in western societies as individualized and open to choice. PMID:16963485

    Our study group has developed a unique combined biological technology to treat high-strength organic wastewaters from the industries of dyestuff, pharmaceutical, chemical engineering and zymolysis by using the principles of anaerobic ecological niche and bio-phase separation. The study obtained five national invention patents and eight patent equipments. This technology contains four kernel processes - two-phase anaerobic-aerobic process, hydrolysis-acidification-oxidation process, UASBAF-oxidation process, and internal cycling-hydrolysis-oxidation process. Fifteen pilot projects were accomplished in the basins of Tai Lake, Huai River, Liao River and Songhua River, and their total capital investment reached 185.214 million Yuan (RMB). Compared to conventional wastewater treatment technology, the innovative technology is more cost-effective for high-strength organic wastewater treatment, can save capital investment by 15% 30%, lessen land usage by 20% to 40% and decrease the operating cost by 10% to 25%. The operating cost of treatment per cubic meter industrial wastewater could be below 0.6 to 1.4 Yuan (RMB).

    2007-12-01

    This report documents a set of case studies developed to estimate the cost of producing, storing, delivering, and dispensing hydrogen for light-duty vehicles for several scenarios involving metropolitan areas in Alabama. While the majority of the scenarios focused on centralized hydrogen production and pipeline delivery, alternative delivery modes were also examined. Although Alabama was used as the case study for this analysis, the results provide insights into the unique requirements for deploying hydrogen infrastructure in smaller urban and rural environments that lie outside the DOEā€™s high priority hydrogen deployment regions. Hydrogen production costs were estimated for three technologies ā€“ steam-methane reforming (SMR), coal gasification, and thermochemical water-splitting using advanced nuclear reactors. In all cases examined, SMR has the lowest production cost for the demands associated with metropolitan areas in Alabama. Although other production options may be less costly for larger hydrogen markets, these were not examined within the context of the case studies.

  2. Competition and Synergy of Different Technologies in the Subsurface: A Case Study for CCS vs. Geothermal Energy Production

    NASA Astrophysics Data System (ADS)

    2013-04-01

    Global climate change, shortage of resources and the resulting turn towards renewable sources of energy lead to a growing demand for the utilization of subsurface systems. Among these competing uses are Carbon Capture and Storage (CCS), geothermal energy, nuclear waste disposal, "renewable" methane or hydrogen storage as well as the ongoing production of fossil resources like oil, gas, and coal. The different uses of the subsurface can result in competition for the limited subsurface space, but in some cases there may also be synergetic effects, if the technologies are combined in a clever way. The idea behind this case study is to investigate the effects of a CCS site on a geothermal power plant operated in its vicinity and present both positive and negative impacts. During CCS operations large quantities of carbon dioxide (CO2) are injected into a storage formation. This causes a pressure increase as the brine in the formation is displaced by CO2. These elevations in pressure can have an extent of several tens of kilometers from the injection well in contrast to the much smaller extent of the CO2 plume. If geothermal power plants operate in the range influenced by pressure evaluation, this may have an impact on their performance. For example: Increased discharge of "warm" brine could be favorable for geothermal power plants as the time until thermal depletion of the reservoir may also increase Early breakthrough of the cold water front between an injection and an extraction well due to a brine discharge "pushing" the cold water front towards the extraction well may lead to a decrease in performance of the power plant Of course, there is a huge number of possible hydrogeological settings and technical configurations for geothermal power production that may be combined to an even larger number of possible scenarios. In this work however we use a simple model setup in which we incorporate and vary the parameters that we think are crucial. Only porous (not fractured) aquifer systems are considered here with a geothermal doublet system (cold water injection and warm water withdrawal). The CCS operation is assumed to take place in the same layer as the geothermal power/heat generation. The CO2 injection itself is not simulated, instead the brine discharge is implemented by an increase of pressure at one side of the domain with respect to the initial conditions. The discharge is varied by changing the pressure at the boundary within a range plausible for CCS operations. Different configurations of the extraction and injection wells of the doublet system with respect to a CCS operation are tested and compared to a reference system without the effect of increased brine discharge. With this work we want to explore the relevance of possible positive or negative impacts of a CCS operation on the performance of a geothermal power plant.

    Being able to manage and adjust insulin doses is a key part of managing type-1 diabetes. Children and adolescents with type-1 diabetes mellitus often have serious difficulties with this dosage adjustment. Therefore, this paper aims to investigate the impact of using novel mobile, web and communication technologies in assisting their therapy and treatment. A trial was conducted in the north-eastern part of Germany to evaluate the impact of the ā€œMobil Diabā€, a mobile diabetes management system, on the clinical outcome. 68 subjects aged between 8 and 18 years, divided randomly into control and intervention groups, were included into the study. Metrics such as changes in the quality of metabolic control, changes in psychological parameters, usability and acceptance of the technology were used for evaluation purpose. Metabolic control was mainly assessed by the mean HbAlc. Analysis showed a good acceptance of the proposed system. An overall improvement in mean levels of HbA1c was observed, however further studies will be conducted to prove evidence of the weight and BMI improvements. Moreover, initial indications of positive impact on the improvement in psychological parameters were presumed based on the result of the conducted study. The system appeared to be an efficient and time saving tool in diabetes management. PMID:25563223

    Performance advantages of the new digital technologies are widely acknowledged, but it has proven difficult for utilities to derive business cases for justifying investment in these new capabilities. Lack of a business case is often cited by utilities as a barrier to pursuing wide-scale application of digital technologies to nuclear plant work activities. The decision to move forward with funding usually hinges on demonstrating actual cost reductions that can be credited to budgets and thereby truly reduce O&M or capital costs. Technology enhancements, while enhancing work methods and making work more efficient, often fail to eliminate workload such that it changes overall staffing and material cost requirements. It is critical to demonstrate cost reductions or impacts on non-cost performance objectives in order for the business case to justify investment by nuclear operators. This Business Case Methodology approaches building a business case for a particular technology or suite of technologies by detailing how they impact an operator in one or more of the three following areas: Labor Costs, Non-Labor Costs, and Key Performance Indicators (KPIs). Key to those impacts will be identifying where the savings are ā€œharvestable,ā€ meaning they result in an actual reduction in headcount and/or cost. The report consists of a Digital Technology Business Case Methodology Guide and an accompanying spreadsheet workbook that will enable the user to develop a business case.

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

    We studied an artificial intelligent assisted interaction between a computer and a human with severe speech and physical impairments (SSPI). In order to speed up AAC, we extended a former study of typing performance optimization using a framework that included head movement controlled assistive technology and an onscreen writing device. Quantitative and qualitative data were collected and analysed with mathematical methods, manual interpretation and semi-supervised machine video annotation. As the result of our research, in contrast to the former experiment's conclusions, we found that our participant had at least two different typing strategies. To maximize his communication efficiency, a more complex assistive tool is suggested, which takes the different methods into consideration. PMID:26294553

    2015-01-01

    Business incubators can play a major role in helping to turn a business idea into a technology-based organization that is economically efficient. However, there is a shortage in the literature regarding the efficiency evaluation and productivity evolution of the new technology-based firms (NTBFs) in the incubation scope. This study develops a model based on the data envelopment analysis (DEA) methodology, which allows the incubated NTBFs to evaluate and improve the efficiency of their management. Moreover, the Malmquist index is used to examine productivity change. The index is decomposed into multiple components to give insights into the root sources of productivity change. The proposed model was applied in a case study with 13 NTBFs incubated. From that study, we conclude that inefficient firms invest excessively in research and development (R&D), and, on average, firms have a productivity growth in the period of study. PMID:25874266

From that study, we conclude that inefficient firms invest excessively in research and development (R&D), and, on average, firms have a productivity growth in the period of study. PMID:25874266

    A BigData case study is described where multiple datasets from several satellites, high-resolution global meteorological data, social media and in-situ observations are combined using machine learning on a distributed cluster using an automated workflow. The global particulate dataset is relevant to global public health studies and would not be possible to produce without the use of the multiple big datasets, in-situ data and machine learning.To greatly reduce the development time and enhance the functionality a high level language capable of parallel processing has been used (Matlab). A key consideration for the system is high speed access due to the large data volume, persistence of the large data volumes and a precise process time scheduling capability.

    The results are described of an application of multiattribute analysis to the evaluation of high leverage prototyping technologies in the automation and robotics (A and R) areas that might contribute to the Space Station (SS) Freedom baseline design. An implication is that high leverage prototyping is beneficial to the SS Freedom Program as a means for transferring technology from the advanced development program to the baseline program. The process also highlights the tradeoffs to be made between subsidizing high value, low risk technology development versus high value, high risk technology developments. Twenty one A and R Technology tasks spanning a diverse array of technical concepts were evaluated using multiattribute decision analysis. Because of large uncertainties associated with characterizing the technologies, the methodology was modified to incorporate uncertainty. Eight attributes affected the rankings: initial cost, operation cost, crew productivity, safety, resource requirements, growth potential, and spinoff potential. The four attributes of initial cost, operations cost, crew productivity, and safety affected the rankings the most.

    These two case studies assessed technology-based programs for promoting walking fluency and improving foot-ground contact during walking with a man and a woman with multiple disabilities, respectively. The man showed breaks during walking and the woman presented with toe walking. The technology used in the studies included a microprocessor with specific software, an MP3 with the recordings of preferred stimulus items, and optic sensors. Both studies were carried out according to an ABAB design. In Study I, the optic sensors were activated when the man crossed small marks distributed along the travel routes. At each sensor's activation, the man received a brief period of preferred stimulation. In Study II, the woman received preferred stimulation when the sensors at the toe and the heel of her shoes were activated in close time proximity. The man walked virtually without breaks and improved his mood (with an increase in indices of happiness) during the intervention phases of the study. The woman largely increased her percentages of steps with adequate foot-ground contact, which reached a mean of about 80 during the second intervention phase. The results were discussed in terms of rehabilitation implications and technology demands. PMID:22093655

    Introduction: The Beacon Community in Cincinnati, Ohio was an innovative, community-wide initiative to use technology to transform care. One important feature was the development of regional alerts to notify practices when patients were hospitalized or seen in the emergency department. The purpose of this paper is to describe the way in which technology engages the improvement process, and to describe the early stages of learning how to use technology to enhance quality improvement. Methods: We interviewed key Beacon leaders as well as providers and office staff in selected practices. We also collected preliminary data from practices that reflected handling of alerts, including the number of asthma related alerts received and followed up. Results: Regional alerts, supplied by the community-wide health information exchange, were a significant addition to the quality improvement effort in that they enabled practices to identify and follow up with additional children at risk. An important finding was the substantial effort at the practice level to integrate technology into ongoing patient care. Conclusions: Developing the technology for community wide alerts represented a significant endeavor in the Cincinnati Beacon Community. However, the technology was just the first step. Despite extra effort and time required on the part of individual practices, they reported that the value of having alerts was high. Hospital and ED visits represent some of the most costly aspects of care, and an efficient process for intervening with children using these costly services was seen as of significant value.

    The Technological Change in Health Care Research Network collected unique patient-level data on three procedures for treatment of heart attack patients (catheterization, coronary artery bypass grafts and percutaneous transluminal coronary angioplasty) for 17 countries over a 15-year period to examine the impact of economic and institutional factors on technology adoption. Specific institutional factors are shown to be important to the uptake of these technologies. Health-care systems characterized as public contract systems and reimbursement systems have higher adoption rates than public-integrated health-care systems. Central control of funding of investments is negatively associated with adoption rates and the impact is of the same magnitude as the overall health-care system classification. GDP per capita also has a strong role in initial adoption. The impact of income and institutional characteristics on the utilization rates of the three procedures diminishes over time. PMID:18972326

    2012-01-01

    The present three single-case studies assessed the effectiveness of technology-based programs to help three persons with multiple disabilities exercise adaptive response schemes independently. The response schemes included (a) left and right head movements for a man who kept his head increasingly static on his wheelchair's headrest (Study I), (b) left- and right-arm movements for a woman who tended to hold both arms/hands tight against her body (Study II), and (c) touching object cues on a computer screen for a girl who rarely used her residual vision for orienting/guiding her hand responses. The technology involved microswitches/sensors to detect the response schemes and a computer/control system to record their occurrences and activate preferred stimuli contingent on them. Results showed large increases in the response schemes targeted for each of the three participants during the intervention phases of the studies. The importance of using technology-based programs as tools for enabling persons with profound and multiple disabilities to practice relevant responses independently was discussed. PMID:22240142

    Nole, Gabriele; Lasaponara, Rosa

    2015-04-01

    Up to nowadays, satellite data have become increasingly available, thus offering a low cost or even free of charge unique tool, with a great potential for operational monitoring of vegetation cover, quantitative assessment of urban expansion and urban sprawl, as well as for monitoring of land use changes and soil consumption. This growing observational capacity has also highlighted the need for research efforts aimed at exploring the potential offered by data processing methods and algorithms, in order to exploit as much as possible this invaluable space-based data source. The work herein presented concerns an application study on the monitoring of vegetation cover and urban sprawl conducted with the use of satellite Landsat TM data. The selected test site is the Iguazu park highly significant, being it one of the most threatened global conservation priorities (http://whc.unesco.org/en/list/303/). In order to produce synthetic maps of the investigated areas to monitor the status of vegetation and ongoing subtle changes, satellite Landsat TM data images were classified using two automatic classifiers, Maximum Likelihood (MLC) and Support Vector Machines (SVMs) applied by changing setting parameters, with the aim to compare their respective performances in terms of robustness, speed and accuracy. All process steps have been developed integrating Geographical Information System and Remote Sensing, and adopting free and open source software. Results pointed out that the SVM classifier with RBF kernel was generally the best choice (with accuracy higher than 90%) among all the configurations compared, and the use of multiple bands globally improves classification. One of the critical elements found in the case of monitoring of urban area expansion is given by the presence of urban garden mixed with urban fabric. The use of different configurations for the SVMs, i.e. different kernels and values of the setting parameters, allowed us to calibrate the classifier also to cope with a specific need, as in our case, to achieve a reliable discrimination of urban from non urban areas.

  7. Science-Technology-Society literacy in college non-majors biology: Comparing problem/case studies based learning and traditional expository methods of instruction

    Peters, John S.

    This study used a multiple response model (MRM) on selected items from the Views on Science-Technology-Society (VOSTS) survey to examine science-technology-society (STS) literacy among college non-science majors' taught using Problem/Case Studies Based Learning (PBL/CSBL) and traditional expository methods of instruction. An initial pilot investigation of 15 VOSTS items produced a valid and reliable scoring model which can be used to quantitatively assess student literacy on a variety of STS topics deemed important for informed civic engagement in science related social and environmental issues. The new scoring model allows for the use of parametric inferential statistics to test hypotheses about factors influencing STS literacy. The follow-up cross-institutional study comparing teaching methods employed Hierarchical Linear Modeling (HLM) to model the efficiency and equitability of instructional methods on STS literacy. A cluster analysis was also used to compare pre and post course patterns of student views on the set of positions expressed within VOSTS items. HLM analysis revealed significantly higher instructional efficiency in the PBL/CSBL study group for 4 of the 35 STS attitude indices (characterization of media vs. school science; tentativeness of scientific models; cultural influences on scientific research), and more equitable effects of traditional instruction on one attitude index (interdependence of science and technology). Cluster analysis revealed generally stable patterns of pre to post course views across study groups, but also revealed possible teaching method effects on the relationship between the views expressed within VOSTS items with respect to (1) interdependency of science and technology; (2) anti-technology; (3) socioscientific decision-making; (4) scientific/technological solutions to environmental problems; (5) usefulness of school vs. media characterizations of science; (6) social constructivist vs. objectivist views of theories; (7) impact of cultural religious/ethical views on science; (8) tentativeness of scientific models, evidence and predictions; (9) civic control of technological developments. This analysis also revealed common relationships between student views which would not have been revealed under the original unique response model (URM) of VOSTS and also common viewpoint patterns that warrant further qualitative exploration.

  9. Evaluating odour control technologies using reliability and sustainability criteria--a case study for water treatment plants.

    PubMed

    Kraakman, N J R; Estrada, J M; Lebrero, R; Cesca, J; MuƱoz, R

    2014-01-01

    Technologies for odour control have been widely reviewed and their optimal range of application and performance has been clearly established. Selection criteria, mainly driven by process economics, are usually based on the air flow volume, the inlet concentrations and the required removal efficiency. However, these criteria are shifting with social and environmental issues becoming as important as process economics. A methodology is illustrated to quantify sustainability and robustness of odour control technology in the context of odour control at wastewater treatment or water recycling plants. The most commonly used odour abatement techniques (biofiltration, biotrickling filtration, activated carbon adsorption, chemical scrubbing, activated sludge diffusion and biotrickling filtration coupled with activated carbon adsorption) are evaluated in terms of: (1) sustainability, with quantification of process economics, environmental performance and social impact using the sustainability metrics of the Institution of Chemical Engineers; (2) sensitivity towards design and operating parameters like utility prices (energy and labour), inlet odour concentration (H2S) and design safety (gas contact time); (3) robustness, quantifications of operating reliability, with recommendations to improve reliability during their lifespan of operations. The results show that the odour treatment technologies with the highest investments presented the lowest operating costs, which means that the net present value (NPV) should be used as a selection criterion rather than investment costs. Economies of scale are more important in biotechniques (biofiltration and biotrickling filtration) as, at increased airflows, their reduction in overall costs over 20 years (NPV20) is more extreme when compared to the physical/chemical technologies (chemical scrubbing and activated carbon filtration). Due to their low NPV and their low environmental impact, activated sludge diffusion and biotrickling filtration are in general the most cost-effective, and probably the technologies to be considered first for odour treatment in a wastewater treatment or water recycling plant. When, in an economical and risk evaluation, the reliability is counted to be as relevant as the overall costs, a hybrid technology (biotrickling filtration with activated carbon polishing) would be comparable to biotrickling filtration and activated sludge diffusion as the most preferred technologies, when all technologies are designed to have a 99% reduction of H2S and a 95% reduction of the odour concentration.

    In pursuit of such missions as Apollo, the National Aeronautics and Space Administration has called into being unique equipment that obviously has little direct application beyond the achievement of mission objectives. Yet, to assume that further direct application of space program hardware is somehow a measure of the industrial benefits accruing to the nation is to misunderstand how the creation of new technology affects modern industrial capability. This document presents a profile of the significant ways in which technological developments in response to aerospace mission requirements have been coupled into industrial practice, with the result being that improved products and processes are now being utilized to benefit the nation.

    2010-06-01

    The aim of this case study was to describe two District Nurses' (DN) experiences of using information and communication technology (ICT) to communicate with chronically ill people in their homes. An electronic messaging program via computers and mobile phones with an Internet connection was used, enabling DNs and the ill people to exchange messages to and from anywhere. The program comprised different virtual rooms, and communication was via text messages. The DNs in this study used the program two to four times each week from November 2003 to March 2004. Semi-structured interviews were performed before, during and after the implementation of the new technology and were analysed using thematic content analysis. The results showed that the DNs felt that the technology increased accessibility to nursing care through a more direct communication with the ill person meaning that a more trusting relationship could be created. The DNs also experienced that the use of ICT saved working time. This study indicates that the use of ICT for communication allowed the DN to better support a chronically ill person at home leading to improved home nursing care. This method of communication cannot replace physical presence, but can be seen as a complement to nursing care at home. PMID:20030770

Rather than providing research results, this scoping study identifies important research questions along with the level of effort necessary to address these questions and the costs, risks, and benefits of pursuing alternative research questions. In approaching these questions and level of effort, feasibility and timing were important considerations. The Commission has specified Summer 2005 as the latest date for completing this research in time to update the 2008 version of California's Energy Code (Title 24).

  6. Twenty-first century learning in schools: A case study of New Technology High School in Napa, California.

    PubMed

    Pearlman, Bob

    2006-01-01

    The most pertinent question concerning teaching and learning in the twenty-first century is not what knowledge and skills students need--that laundry list was identified over a decade ago--but rather how to foster twenty-first century learning. What curricula, experiences, assessments, environments, and technology best support twenty-first century learning? New Technology High School (NTHS) in Napa, California, is one example of a successful twenty-first century school. In this chapter, the author describes the components of this exemplary high school, illustrating an environment that will cultivate twenty-first century student learning. New Technology High School began by defining eight learning outcomes, aligned with the standards of the Partnership for 21st Century Skills; to graduate, students demonstrate mastery of these outcomes through an online portfolio. To help students achieve the outcomes, NTHS employs project- and problem-based learning. Whereas in traditional classrooms students work alone on short-term assignments that do not lend themselves to deep understanding, the project-based learning approach has students working in teams on long-term, in-depth, rigorous projects. Students' work is supported by the school's workplace-like environment and effectiv use of technology. Meaningful assessment is essential to project-based learning; students receive continuous feedback, helping them become self-directed learners. In fact, NTHS uses outcome-based grading through which students constantly know how they are performing on the twenty-first century outcomes. Research has shown that NTHS graduates are better prepared for postsecondary education, careers, and citizenship than their peers from other schools. To facilitate twenty-first century learning, all schools need to rethink their approach to teaching and learning. New Technology High School is one way to do so. PMID:17017260

  7. The case study approach

    PubMed Central

    2011-01-01

    The case study approach allows in-depth, multi-faceted explorations of complex issues in their real-life settings. The value of the case study approach is well recognised in the fields of business, law and policy, but somewhat less so in health services research. Based on our experiences of conducting several health-related case studies, we reflect on the different types of case study design, the specific research questions this approach can help answer, the data sources that tend to be used, and the particular advantages and disadvantages of employing this methodological approach. The paper concludes with key pointers to aid those designing and appraising proposals for conducting case study research, and a checklist to help readers assess the quality of case study reports.

    Genomics, transcriptomics, proteomics and fluxomics are powerful omics-technologies that play a major role in today's research. For each of these techniques good sample quality is crucial. Major factors contributing to the quality of a sample is the actual sampling procedure itself and the way the sample is stored directly after sampling. It has already been described that RNAlater can be used to store tissues and cells in a way that the RNA quality and quantity are preserved. In this paper, we demonstrate that quaternary ammonium salts (RNAlater) are also suitable to preserve and store samples from Saccharomyces cerevisiae for later use with the four major omics-technologies. Moreover, it is shown that RNAlater also preserves the cell morphology and the potential to recover growth, permitting microscopic analysis and yeast cell culturing at a later stage. PMID:23417260

    In this paper, we review the key solutions that enabled evolution of the lead optimization screening support process at Bristol-Myers Squibb (BMS) between 2004 and 2009. During this time, technology infrastructure investment and scientific expertise integration laid the foundations to build and tailor lead optimization screening support models across all therapeutic groups at BMS. Together, harnessing advanced screening technology platforms and expanding panel screening strategy led to a paradigm shift at BMS in supporting lead optimization screening capability. Parallel SAR and structure liability relationship (SLR) screening approaches were first and broadly introduced to empower more-rapid and -informed decisions about chemical synthesis strategy and to broaden options for identifying high-quality drug candidates during lead optimization.

    The report examines the potential for reducing emissions of global warming gases (e.g. CO2) and NOx through adoption of demand-side technologies. The study covers the period from 1991 to 2011. The direct efficiency effects of technologies and space conditioning measures were investigated for two case study areas, California South Coast and State of Vermont. A spreadsheet model was developed for this project to investigate the residential and commercial sector demand-side management (DSM) potential in the California South Coast. The Long-Term Industrial Energy Forecasting (LIEF) model was adapted for the California South Coast industrial sector. The ENERGY2020 integrated energy model, coupled with a macroeconomic system was used for Vermont. Other available DSM models are also discussed. Included in the analysis were each region's current stock of energy-using equipment, building square footage, and the currently mandated State and Federal energy efficiency standards. Business-as-usual, financial incentives, and technology forcing scenarios were evaluated.

  11. Considering user attitude in early Development of environmentally friendly technology: a case study of NoMix toilets.

    2006-08-15

    Urine source separation (NoMix technology) has been proposed as a sustainable alternative to centralized wastewater treatment systems. Radical changes necessitate an early inclusion of sociological expertise, thus offering a real chance fortransdisciplinary collaboration. The practical aim of our survey is to find out how users accept and use existing NoMixtoilets and how this could be encouraged. We collected 1249 questionnaires from 2002 to 2004 in one Swiss school and one Swiss research institute. The technological immaturity of NoMix toilets was noted by many. Nevertheless, acceptance was high: 72% liked the idea and 86% would move into apartments with NoMix toilets. Moreover, most users found that NoMix toilets equal conventional toilets with respect to design (78%), hygiene (84%), and smell (78%). Like many other innovations, the NoMix technology only functions properly if it is used adequately, which we demonstrate for water saving and sitting to urinate. Many users adopted this behavior, e.g., 72% sat. Because perception and use of NoMix toilets is subjective, it can be influenced with certain measures such as good information and cleaning, or discussions with peers. We discuss the importance of social psychology for understanding the factors that influence the acceptance of environmentally friendly innovations. PMID:16955875

    There is a growing emphasis on the research-teaching nexus, and there are many innovative ways to incorporate research materials and methods in undergraduate teaching. Solar Physics is a cross-disciplinary subject and offers the ideal opportunity for research-enhanced teaching (1). In this presentation, I outline i) how student-led teaching of research content and methods is introduced in an undergraduate module in Solar Physics, and ii) how electronic learning and teaching can be used to improve students' learning of mathematical concepts in Solar Physics. More specifically, I discuss how research literature reviewing and reporting methods can be embedded and developed systematically throughout the module with aligned assessments. Electronic feedback and feedforward (2) are given to the students in order to enhance their understanding of the subject and improve their research skills. Other technology-enhanced teaching approaches (3) are used to support students' learning of the more quantitative components of the module. This case study is particularly relevant to a wide range of pedagogical contexts (4) as the Solar Physics module is taught to students following undergraduate programs in Geology, Earth Sciences, Environmental Geology as well as Planetary Science with Astronomy in the host Department.

    Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

    With the growth in the number of elderly and people with chronic diseases, the number of hospital services will need to increase in the near future. With myriad of information technologies utilized daily and crucial information-sharing tasks performed at hospitals, understanding the relationship between task performance and information system has become a critical topic. This research explored the resource pooling of hospital management and considered a computed tomography (CT) patient-referral mechanism between two hospitals using the information system theory framework of Task-Technology Fit (TTF) model. The TTF model could be used to assess the 'match' between the task and technology characteristics. The patient-referral process involved an integrated information framework consisting of a hospital information system (HIS), radiology information system (RIS), and picture archiving and communication system (PACS). A formal interview was conducted with the director of the case image center on the applicable characteristics of TTF model. Next, the Icam DEFinition (IDEF0) method was utilized to depict the As-Is and To-Be models for CT patient-referral medical operational processes. Further, the study used the 'leagility' concept to remove non-value-added activities and increase the agility of hospitals. The results indicated that hospital information systems could support the CT patient-referral mechanism, increase hospital performance, reduce patient wait time, and enhance the quality of care for patients.

    Objectives To assess the impact of technology-based changes on student learning, skill development, and satisfaction in a patient-case workshop. Design A new workshop format for a course was adopted over a 3-year period. Students received and completed patient cases and obtained immediate performance feedback in class instead of preparing the case prior to class and waiting for instructors to grade and return their cases. The cases were designed and accessed via an online course management system. Assessment Student satisfaction was measured using end-of-course surveys. The impact of the technology-based changes on student learning, problem-solving, and critical-thinking skills was measured and compared between the 2 different course formats by assessing changes in examination responses. Three advantages to the new format were reported: real-life format in terms of time constraint for responses, a team learning environment, and expedient grading and feedback. Students overwhelmingly agreed that the new format should be continued. Students' examination scores improved significantly under the new format. Conclusion The change in delivery of patient-case workshops to an online, real-time system was well accepted and resulted in enhanced learning, critical thinking, and problem-solving skills.

    Robb, A.J. III; Hoggatt, P.R.

    1995-12-01

    Hydrocarbon containing soil was bioremediated at a combination wastewater and slop oil skim evaporation pond utilizing cost effective low technology resources. Fluids and sludge from the football field-sized pond were extraction procedure toxicity and purgeable organics tested, and total petroleum hydrocarbon (TPH) concentrations determined. An impact risk analysis was performed, and a corrective action plan developed and implemented. The three year project was closely coordinated with the Kansas Corporation Commission (KCC) and the Kansas Department of Health and Environment (KDHE) who established the closure level. The impacted soils at the pond were completely excavated and closure was immediately granted by KDHE for the excavated area. The 24,000 cubic yards of excavated soil were then surface spread on adjacent Mobil property. A nutrient and microbial base was applied to bioaugment the soil. The preapplication land surface and the subsequently land farmed soil was periodically disced and chiseled. A job safety plan including industrial hygiene measures to eliminate workforce exposure was developed and implemented. The final remediation cost analysis amounts to $1.48 per cubic yard compared to the $30 to $150 per cubic yard industry o estimates for similar projects. Several factors were critical in ailing costs to remain so low: (1) assessment and implementation by local in-house staff, (2) conservative remedial action plan and sampling strategy; (3) local contractors; (4) locally available soil amendment; and (5) effective regulatory coordination. The methods described can be used to cost effectively characterize and bioremediate other sites where hydrocarbon-impacted soils exist in similar dry-land environments.

    2014-05-01

    We explore the applicability of noise-based monitoring and imaging techniques in the context of the 2006 Basel stimulation experiment using data from five borehole velocimeters and five surface accelerometers located around the injection site. We observe a significant perturbation of medium properties associated with the reservoir stimulation. The transient perturbation, with a duration of 20-30 days, reaches its maximum about 15 days after shut in, when microseismic activity has ceased; it is thus associated with aseismic deformation. Inverting relative velocity change and decorrelation observations using techniques developed and applied on laboratory and local to regional seismological scales, we can image the associated deformation pattern. We discuss limits of the the frequency- and lapse-time dependent resolution and suggestions for improvements considering the 3-D network geometry together with wave propagation models. The depth sensitivity of the analyzed wave field indicates resolution of perturbation in the shallow parts of the sedimentary layer above the stimulated deep volume located in the crystalline base layer. The deformation pattern is similar to InSAR/satellite observations associated with CO2 sequestration experiments, and indicates the transfer of deformation beyond scales associated with the instantaneously stimulated volume. Our detection and localization of delayed induced shallow aseismic transient deformation indicates that monitoring the evolution of reservoir properties using the ambient seismic field provides observables that complement information obtained with standard microseismic approaches. The results constitute a significant advance for the resolution of reservoir dynamics; the technology has the potential to provide critical constraints in related geotechnical situations associated with fluid injection, fracking, (nuclear) waste management, and carbon capture and storage.

    For a Mars Expedition, aerobrakes can play a vital role in several major mission events, including aerocapture to achieve orbit and descent to the planetary surface both at Mars and upon return to Earth. The feasibility of aerobrake designs will depend upon material and structures technologies because they will serve as a key factor in determining: (1) aerobrake mass and mass fraction; (2) the extent to which aerobrakes can survive the thermal environment. This is especially important for reusable aerobrakes. With the cancellation of the Aeroassist Flight Experiment, the effort to validate aerobrake designs has focused on laboratory test and analysis; (3) the feasibility of assembling and/or deploying large aerobrakes. On-orbit assembly is a critical issue for all spacecraft intended for Mars exploration missions. Current studies are addressing options related to inspace assembly and construction; and (4) configuration lift-to-drag (L/D) ratio. High L/D increases convective heating, whereas low L/D emphasizes radiative heating. In general, the lowest L/D design that can satisfy mission requirements is preferred.

    Laparoscopic radiofrequency ablation of uterine leiomyomas with a new Federal Drug Administration (FDA)-approved device, a device that delivers radiofrequency energy, is a novel procedure that aims to meet patient and physician demand for effective, minimally invasive leiomyoma treatment. However, as a new procedure, the durability of symptom relief, the safety in widespread use, and ultimately the comparative effectiveness of radiofrequency ablation of leiomyomas need further study. In June 2013, the University of California Fibroid Network, a collaboration of the five University of California Departments of Obstetrics and Gynecology, launched the Uterine Leiomyoma Treatment with Radiofrequency Ablation Study, an investigator-initiated early postmarket approval clinical trial of radiofrequency ablation of leiomyomas. In this commentary, we provide a review of the FDA approval process for medical devices using the device that delivers radiofrequency energy as a case study and describe significant limitations of this process that may adversely affect clinical care. We show how the deficiencies in the FDA process have challenged our ability to conduct independent early postmarket research evaluating the safety and long-term effectiveness of this novel technology. Our experience validates the Institute of Medicine's recommendation that advancements in surgical technology introducing new treatments without long-term effectiveness data, comparative study, or both should emerge onto the market under research conditions. Until the FDA requires more rigorous study of novel devices, we suggest ways of working together as a community of gynecologic surgeons to evaluate promising new technologies in early postmarket studies, putting research before widespread adoption of surgical innovation.

    Over recent years, heat pump water heaters (HPWHs) have become more readily available and more widely adopted in the marketplace. For a 6-month period, the Building America team Consortium for Advanced Residential Buildings monitored the performance of a GE Geospring HPWH in Windermere, Florida. The study found that the HPWH performed 144% more efficiently than a traditional electric resistance water heater, saving approximately 64% on water heating annually. The monitoring showed that the domestic hot water draw was a primary factor affecting the system's operating efficiency.

    Diffusion of medical technology and the growing proportion of elderly people in the population are generally regarded as major contributors to the increasing health care expenditure in the industrialised world. This study explores the importance of one specific factor in this process, the change in the use of technology among elderly patients. In some instances, a new technology is first used among younger patients and then gradually extended to the elderly. Two such cases are studied, both representing costly procedures: coronary bypass surgery (treatment of coronary heart disease) and dialysis (treatment of uraemia). In both cases, we demonstrate significant diffusion to older age groups. It is also tentatively concluded that the diffusion of technology could have an important effect on per capita health care expenditure among the oldest of the old. PMID:11820681

    With an increasing awareness that active engagement between policy decision makers, HTA agencies, regulators and payers with industry in the premarket space is needed, a disruptive comprehensive approach is described which moves the evidentiary process exclusively into this space. Single harmonized studies pre-market to address regulatory and coverage needs and expectations are more likely to be efficient and less costly and position evidence to drive rather than test innovation. An example of such a process through the MaRS EXCITE program in Ontario, Canada, now undergoing proof of concept, is briefly discussed. Other examples of dialogue between decision makers and industry pre-market are provided though these are less robust than a comprehensive evidentiary approach. PMID:26560412

    It is an undeniable fact that isolated areas lack sufficient energy resources and that energy supply is central in order to achieve sustainable development goals. On the other hand, agricultural materials, whose trade profit fluctuates in low levels, are produced locally in wide range. As a result, the implementation of an alternative, more effective approach, which ensures the sustainability in social, economical and environmental dimension, is a crucial issue for developing countries. In this particular study, in order to cover the local energy needs, the possibility of installing a small biodiesel plant in a rural area of Cameroon, has been analyzed. The final biodiesel product can also be disposed directly to the market leading to an additional local income. In this paper, both the monthly potential of palm oil in Mangoā€™o region and the recommended biodiesel production process are presented. Some significant benefits that can be achieved are independence from fossil fuels, mechanization of palm oil production process and additional prevention of local depopulation.

    Taking climate change scenarios into account, rainfall patterns are likely to change over the coming decades in eastern Africa. In brief, large parts of eastern Africa are expected to experience a wetting, including seasonality changes. Gullies are threshold phenomena that accomplish most of their geomorphic change during short periods of strong rainfall. Understanding the links between geomorphic change and rainfall characteristics in detail, is thus crucial to ensure the sustainability of future land management. In this study, we present image-based 3D modelling as a low-cost, flexible and rapid method to quantify gully morphology from terrestrial photographs. The methodology was tested on two gully heads in Northern Ethiopia. Ground photographs (n = 88-235) were taken during days with cloud cover. The photographs were processed in PhotoScan software using a semi-automated Structure from Motion-Multi View Stereo (SfM-MVS) workflow. As a result, full 3D models were created, accurate at cm level. These models allow to quantify gully morphology in detail, including information on undercut walls and soil pipe inlets. Such information is crucial for understanding the hydrogeomorphic processes involved. Producing accurate 3D models after each rainfall event, allows to model interrelations between rainfall, land management, runoff and erosion. Expected outcomes are the production of detailed vulnerability maps that allow to design soil and water conservation measures in a cost-effective way. Keywords: 3D model, Ethiopia, Image-based 3D modelling, Gully, PhotoScan, Rainfall.

  18. Technology Solutions Case Study: Improving Comfort in Hot-Humid Climates with a Whole-House Dehumidifier

    2013-11-01

    In order to quantify the performance of a combined whole-house dehumidifier (WHD) AC system, researchers from the Consortium of Advanced Residential Buildings (CARB) team monitored the operation of two Lennox AC systems coupled with a Honeywell DH150 TrueDRY whole-house dehumidifier for a six-month period. By using a WHD to control moisture levels (latent cooling) and optimizing a central AC to control temperature (sensible cooling), improvements in comfort can be achieved while reducing utility costs. Indoor comfort for this study was defined as maintaining indoor conditions at below 60% RH and a humidity ratio of 0.012 lbm/lbm while at common dry bulb set point temperatures of 74Ā°-80Ā°F. In addition to enhanced comfort, controlling moisture to these levels can reduce the risk of other potential issues such as mold growth, pests, and building component degradation. Because a standard AC must also reduce dry bulb air temperature in order to remove moisture, a WHD is typically needed to support these latent loads when sensible heat removal is not desired.

    Utility load management programs--including direct load control and interruptible load programs--were employed by utilities in the past as system reliability resources. With electricity industry restructuring, the context for these programs has changed; the market that was once controlled by vertically integrated utilities has become competitive, raising the question: can existing load management programs be modified so that they can effectively participate in competitive energy markets? In the short run, modified and/or improved operation of load management programs may be the most effective form of demand-side response available to the electricity system today. However, in light of recent technological advances in metering, communication, and load control, utility load management programs must be carefully reviewed in order to determine appropriate investments to support this transition. This report investigates the feasibility of and options for modifying an existing utility load management system so that it might provide reliability services (i.e. ancillary services) in the competitive markets that have resulted from electricity industry restructuring. The report is a case study of Southern California Edison's (SCE) load management programs. SCE was chosen because it operates one of the largest load management programs in the country and it operates them within a competitive wholesale electricity market. The report describes a wide range of existing and soon-to-be-available communication, control, and metering technologies that could be used to facilitate the evolution of SCE's load management programs and systems to provision of reliability services. The fundamental finding of this report is that, with modifications, SCE's load management infrastructure could be transitioned to provide critical ancillary services in competitive electricity markets, employing currently or soon-to-be available load control technologies.
