  1. Dispersive mudslide-induced tsunamis

    Directory of Open Access Journals (Sweden)

    1998-01-01

    Full Text Available A nonlinear nested model for mudslide-induced tsunamis is proposed in which three phases of the life of the wave, i.e. the generation, far-field propagation and costal run-up are described by means of different mathematical models, that are coupled through appropriate matching procedures. The generation and run-up dynamics are simulated through a nonlinear shallow-water model with movable lateral boundaries: in the generation region two active layers are present, the lower one describing the slide descending on a sloping topography. For the intermediate phase, representing wave propagation far from the generation region, the hydrostatic assumption is not assumed as appropriate in general and, therefore, a nonlinear model allowing for weak phase dispersion, namely a Kadomtsev-Petviashvili equation, is used. This choice is made in order to assess the relevance of dispersive features such as solitary waves and dispersive tails. It is shown that in some realistic circumstances dispersive mudslide-induced tsunami waves can be produced over relatively short, distances. In such cases the use of a hydrostatic model throughout the whole tsunami history turns out to give erroneous results. In particular, when solitary waves are generated during the tsunami propagation in the open sea, the resulting run-up process yields peculiar wave forms leading to amplified coastal inundations with respect to a mere hydrostatic context.

    Meso-scale structures from gravitational slope deformation observed in landslides and deep-seated gravitational slope failures are very similar to those of endogenous ones. Therefore we applied palaeostress analysis of fault-slip data for reconstructing the stress field of an active mudslide in Pechgraben, Austria. This complex compound landslide has developed in clayey colluvium and shale and was activated after a certain period of dormancy in June 2013. During the active motion on June 12, 2013, 73 fault-slip traces at 9 locations were measured within the landslide body. The heterogeneous fault-slip data were processed in term of palaeostresses, the reconstructed palaeostress tensor being characterized by the orientations of the three principal stress axes and the stress ratio (which provides the shape of the stress ellipsoid). The results of the palaeostress analysis were compared to airborne laser scan digital terrain models that revealed dynamics and superficial displacements of the moving mass prior and after our survey. The results were generally in good agreement with the observed landslide displacement pattern and with the anticipated stress regime according to Mohr-Coulomb failure criteria and Anderson's theory. The compressional regime was mostly registered at the toe in areas, where a compressional stress field is expected during previous mass-movement stages, or at margins loaded by subsequent landslide bodies from above. On the other hand, extension regimes were identified at the head scarps of secondary slides, subsequently on bulged ridges at the toe and in the zone of horst-and-graben structures in the lower central part of the main landslide body, where the basal slip surface probably had locally convex character. Strike-slip regimes, as well as oblique normal or oblique reverse regimes were observed at the lateral margins of the landslide bodies. The directions of principal stresses could be used as markers of landslide movement directions

  16. Pre-2014 mudslides at Oso revealed by InSAR and multi-source DEM analysis

    Science.gov (United States)

    Kim, J. W.; Lu, Z.; QU, F.

    2014-12-01

    The landslide is a process that results in the downward and outward movement of slope-reshaping materials including rocks and soils and annually causes the loss of approximately $3.5 billion and tens of casualties in the United States. The 2014 Oso mudslide was an extreme event costing nearly 40 deaths and damaging civilian properties. Landslides are often unpredictable, but in many cases, catastrophic events are repetitive. Historic record in the Oso mudslide site indicates that there have been serial events in decades, though the extent of sliding events varied from time to time. In our study, the combination of multi-source DEMs, InSAR, and time-series InSAR analysis has enabled to characterize the Oso mudslide. InSAR results from ALOS PALSAR show that there was no significant deformation between mid-2006 and 2011. The combination of time-series InSAR analysis and old-dated DEM indicated revealed topographic changes associated the 2006 sliding event, which is confirmed by the difference of multiple LiDAR DEMs. Precipitation and discharge measurements before the 2006 and 2014 landslide events did not exhibit extremely anomalous records, suggesting the precipitation is not the controlling factor in determining the sliding events at Oso. The lack of surface deformation during 2006-2011 and weak correlation between the precipitation and the sliding event, suggest other factors (such as porosity) might play a critical role on the run-away events at this Oso and other similar landslides.

    The purpose of this study was to validate the Impact of Event Scale-Revised (IES-R) for adolescents who had experienced the floods and mudslides caused by Typhoon Morakot in Taiwan. The internal consistency, construct validity, and criteria validity of the instrument were examined. Principal component analysis followed by an oblique rotation was used to derive a three-factor solution. These factors were labeled intrusion, hyperarousal, and avoidance; all three factors together accounted for 58.1% of the variance. The total Cronbach's alpha of 0.94 reflected the good internal consistency of the instrument. With reference to diagnosis of posttraumatic stress disorder, the IES-R cutoff point for posttraumatic stress disorder was 19 of 20 with a sensitivity of 85.7% and specificity of 84.1%. In conclusion, the IES-R can be used as a reliable and valid instrument when evaluating psychological distress among adolescents who have experienced a natural disaster, such as flooding and mudslides.

    Full Text Available The aim of this article was to review the factors that influence the aging, relationship of aging with the biological rhythms and new technologies as well as the main theories to explain the aging, and to analysis the causes of aging. The theories to explain the aging could be put into two groups: those based on a program that controlled the regression of the organism and those that postulated that the deterioration was due to mutations. It was concluded that aging was a multifactorial process. Genetic factors indicated the maximum longevity of the individual and environmental factors responsible for the real longevity of the individual. It would be necessary to guarantee from early age the conservation of a natural life rhythm.

  3. Seismic monitoring of soft-rock landslides: New case study at Pechgraben mudslide - Upper Austria

    2016-04-01

    Creeping soft-rock landslides trigger various seismic signals which relate to key dynamics of the slope instability. A new seismic monitoring study is carried out at Pechgraben - Upper Austria, where a clay-shale rich mudslide was reactivated in summer 2013 after heavy rainfalls. The well geophysical instrumentation of the Pechgraben mudslide by the Geological Survey of Austria (LAMOND network including permanent ERT, GPS, piezometers, soil temperature/humidity and photomonitoring) is expected as a better basis for joint interpretation of seismic source processes. Seismic data are acquired by small-aperture (< 30 m) sparse seismic arrays. Potential events are recognized by frequency-time signatures in sonograms, where sonograms are spectrograms featuring a frequency-dependant noise adaptation that enhance the display of weak signal energy down to the noise threshold. Further signal evaluation follows an interactive scheme where semi-automated beam forming method enables for approximate source location. Three seismic arrays where deployed at Pechgraben in October 2015 for an eight days feasibility study. About 200 seismic signals potentially triggered by the landslide were manually picked on night-time measurements. Target signals occur in tremor-like sequences and have duration within 1 - 8 seconds. Local magnitudes are calibrated down to ML -1.5 (Wood-Anderson amplitude ≈ 0.1 μm in 100 m distance). Observed waveforms display high degree of similarity with seismic signals catalogued at other soft-rock landslides suggesting that a general typology of seismic source processes could be established for creeping soft-rock instabilities with potential further implications in landslide mitigation and forecasting.

    2016-03-01

    Full Text Available A qualitative study was conducted to examine the philosophy of technology of K-12 technology leaders, and explore the influence of their thinking on technology decision making. The research design aligned with CORBIN and STRAUSS grounded theory methods, and I proceeded from a research paradigm of critical realism. The subjects were school technology directors and instructional technology specialists, and data collection consisted of interviews and a written questionnaire. Data analysis involved the use of grounded theory methods including memo writing, open and axial coding, constant comparison, the use of purposive and theoretical sampling, and theoretical saturation of categories. Three broad philosophy of technology views were widely held by participants: an instrumental view of technology, technological optimism, and a technological determinist perspective that saw technological change as inevitable. Technology leaders were guided by two main approaches to technology decision making, represented by the categories Educational goals and curriculum should drive technology, and Keep up with technology (or be left behind. The core category and central phenomenon that emerged was that technology leaders approached technology leadership by placing greater emphasis on keeping up with technology, being influenced by an ideological orientation to technological change, and being concerned about preparing students for a technological future.

    2007-01-01

    While there are a myriad of applications for microwave phase shifters in instrumentation and metrology, power combining, amplifier linearization, and so on, the most prevalent use is in scanning phased-array antennas. And while this market continues to be dominated by military radar and tracking platforms, many commercial applications have emerged in the past decade or so. These new and potential applications span low-Earth-orbit (LEO) communications satellite constellations and collision warning radar, an aspect of the Intelligent Vehicle Highway System or Automated Highway System. In any case, the phase shifters represent a considerable portion of the overall antenna cost, with some estimates approaching 40 percent for receive arrays. Ferrite phase shifters continue to be the workhorse in military-phased arrays, and while there have been advances in thin film ferrite devices, the review of this device technology in the previous edition of this book is still highly relevant. This chapter will focus on three types of phase shifters that have matured in the past decade: GaAs MESFET monolithic microwave integrated circuit (MMIC), micro-electromechanical systems (MEMS), and thin film ferroelectric-based devices. A brief review of some novel devices including thin film ferrite phase shifters and superconducting switches for phase shifter applications will be provided. Finally, the effects of modulo 2 phase shift limitations, phase errors, and transient response on bit error rate degradation will be considered.

    2010-05-01

    To characterize superficial deformations of the mudslide in Super-Sauze, southern French Alps, seismic and geotechnical monitoring techniques have been applied simultaneously during a field campaign in July 2009. Based on the method nanoseismic monitoring (Joswig, 2008), we installed three seismic mini-arrays with an aperture of 25-30m, each one consisting of one three-component central-station and three outer vertical-component stations. We identified two different deformation processes caused by the movement of the mudslide: fracture processes within the slope material and superficial fissure development (Walter & Joswig, 2009). The spatiotemporal occurrence of deformation processes identified by nanoseismic monitoring has been verified with geotechnical monitoring systems. GPS devices as well as a small wireless ad-hoc, multi hop sensor network (WSN) have been installed in the slope area. The network consist of 7 connection points, called nodes, that transfer data from different sensors via radio signal directly or over other nodes (Multi Hop) in real-time to a data collection point (gateway). To determine the varying deformation processes, like toppling, spreading, falling and sliding, 6 nodes were equipped with micro-sensors (each with 3-axis acceleration sensor, 2-axis tilt sensor and barometric pressure sensor). In order to monitor the deformation of a recent fissure, one node was equipped with a position-sensor (draw wire displacement transducer). Laboratory tests for the different sensors showed that tilt movements can be detected with an accuracy of +/- 0,06° and a resolution of >0,1°, accelerations with +/- 0,008g and >0,02g and displacements with +/- 0,1mm and >0,1mm. The analysis of data recorded by barometric pressure sensors is quite difficult due to the high natural pressure fluctuations in mountain areas, anyway, the detection of fluctuations of >0,5m was possible. Except the displacement transducers, the geotechnical sensors didn't detect any

    Consumer culture theory helps us take note of the cultural forces and dynamics in which technology consumption is entangled. It enables people to articulate the cultural processes (ideological, mythic, ritualistic, etc.) through which cultural meanings become granted to or denied to technological...... innovations, thus shaping the value of technologies as cultural resources sustaining consumer identities. In its urge to shed light on these aspects, CCT tends to reinforce the gaps and asymmetries between the “socio-cultural” and the “techno-material”, leaving plenty of room for further study.

    This book presents in detail the theory, processes and equipment involved in cold rolling precision forming technologies, focusing on spline and thread shaft parts. The main topics discussed include the status quo of research on cold rolling precision forming technologies; the design and calculation of process parameters; the numerical simulation of cold rolling forming processes; and the equipment used in cold rolling forming. The mechanism of cold rolling forming is extremely complex, and research on the processes, theory and mechanical analysis of spline cold rolling forming has remained very limited to date. In practice, the forming processes and production methods used are mainly chosen on the basis of individual experience. As such, there is a marked lack of both systematic, theory-based guidelines, and of specialized books covering theoretical analysis, numerical simulation, experiments and equipment used in spline cold rolling forming processes – all key points that are included in this book and ill...

    Wolff law was an adaptable principle of bone, Tension-Stress Principle was equal to Distraction Osteogenesis or Distraction Tissue Regeneration, The Natural Reconstruction theory was a new orthopedic perspective proposed by Prof. QIN after deformity correction using Ilizarov technology. The thought about their relationship originated from a social phenomena, that the crowds and the confusion about export choice in Beijing's subway. Ilizarov technology and Wolff law were one concept related to Mechanics, and the former is completely in line with the latter. In other words, Ilizarov technology is an extension of Wolff law, is a repeated process of micro-trauma and continuous repair of bone trabecular initiated by moden engineering, just trabecular formed along the tension-stress direction. With adjustment of mechanical force,doctor can control the process of fracture healing and bone remolding to a certain extent. Natural Reconstruction theory enlarged the defined range of Wolff law obviously. Not only guided orthopedics clinical and basic research,but also related to the dialectical thinking of the doctor-patient relationship in sociology. There was an inevitable connection among Wolff law, Ilizarov technology and Natural Reconstruction theory. The history of discovery and understanding was a continuous process of thinking,practice and integration.

    Occupational therapists use a range of strategies to influence the relationship between person, environment and occupation and facilitate people's participation and inclusion in society. Technology is a fundamental environmental factor capable of enabling inclusion, and occupational therapy models articulate a role for assistive technology (AT) devices and services, but there is a gap between theory, research and practice. The context of AT provision in Australia presents systemic barriers that prevent optimal application of AT devices and services for societal health promotion and in individualised solutions. The Integrating Theory, Evidence and Action method (ITEA) was used to answer the question 'How can occupational therapy support AT provision to enable older people and people with disability?' A wide range of sources were systematically analysed to explore the complexities of AT provision in Australia. The International Classification of Functioning, Disability and Health (ICF) and IMPACT(2) model are used as frameworks to reconstruct evidence into statements that summarise the theory, process and outcomes of AT provision. Analysis of the influence of the global disability rights and local policies and AT provision systems is used to highlight important aspects for occupational therapists to consider in research and practice. Pragmatic recommendations are provided to enable practitioners to translate theory and evidence into action. AT provision can be improved by focusing on evidence for and congruence between theory, process and outcomes, rather than isolated interventions. Occupational therapists should consider the influence of contextual factors on practice, and work with consumers to improve access and equity in AT provision systems. © 2016 Occupational Therapy Australia.

  16. Assessing subaqueous mudslide hazard on the Mississippi River delta front, Part 2: Insights revealed through high-resolution geophysical surveying

    The northern Gulf of Mexico, including the subaqueous Mississippi River delta front (MRDF), has been productive for oil and gas development since the early 1900s. In 1969 cyclic seafloor wave loading associated with the passage of Hurricane Camille triggered subaqueous mudflows across the MRDF, destroying several offshore oil platforms. This incident spurred geophysical and geotechnical studies of the MRDF, which found that the delta front is prone to mass failures on gentle gradients (survey area can be classified into four primary sedimentary facies: mudflow gullies, mudflow lobes, undisturbed prodelta, and undisturbed delta front. Subbottom profiles reveal extensive biogenic gas from 20 to about 80 m water depths on the delta front; sidescan data show a variety of bottleneck slides, mudflow gullies and mudflow noses. Previous studies have attempted to constrain the periodicity and magnitude of subaqueous mudslides on the MRDF. However, large age gaps and varied resolution between datasets result in ambiguity regarding the cause and magnitude of observed bathymetric changes. We present high-temporal resolution MRDF bathymetric variations from 2005 (post Hurricane Katrina), 2009 (relatively quiescent storm period), and 2014 (post 2011 Mississippi River flood). These data yield better magnitude and timing estimates of mass movements. This exercise represents a first step towards (1) assembling a comprehensive geologic dataset upon which future MRDF geohazard assessments can be founded, and (2) understanding the dynamics of a massive passive margin deltaic lobe entering a phase of decline.

  17. Application of a three-dimensional variational method for radar reflectivity data correction in a mudslide-inducing rainstorm simulation

    Science.gov (United States)

    Li, Hongli; Xu, Xiangde

    2017-04-01

    Various types of radars with different horizontal and vertical detection ranges are deployed in China, particularly over complex terrain where radar blind zones are common. In this study, a new variational method is developed to correct three-dimensional radar reflectivity data based on hourly ground precipitation observations. The aim of this method is to improve the quality of observations of various types of radar and effectively assimilate operational Doppler radar observations. A mudslide-inducing local rainstorm is simulated by the WRF model with assimilation of radar reflectivity and radial velocity data using LAPS (Local Analysis and Prediction System). Experiments with different radar data assimilated by LAPS are performed. It is found that when radar reflectivity data are corrected using this variational method and assimilated by LAPS, the atmospheric conditions and cloud physics processes are reasonably described. The temporal evolution of radar reflectivity corrected by the variational method corresponds well to observed rainfall. It can better describe the cloud water distribution over the rainfall area and improve the cloud water analysis results over the central rainfall region. The LAPS cloud analysis system can update cloud microphysical variables and represent the hydrometeors associated with strong convective activities over the rainfall area well. Model performance is improved and the simulation of the dynamical processes and moisture transport is more consistent with observation.

  18. Who’s Afraid of Technological Determinism? Another Look at Medium Theory

    Directory of Open Access Journals (Sweden)

    John Potts

    2008-01-01

    Full Text Available This paper assesses the strengths and weaknesses of medium theory as a model. In surveying the critical reception of medium theory, the paper re-evaluates the charge of technological determinism that has been brought against this theoretical model. Alternative models incorporating technologies and social systems, such as Actor Network Theory, are considered, but the paper affirms the emphasis in medium theory on the intrinsic properties of media technologies. The paper points to the tacit influence of medium theory in everyday claims made for new media technologies and their transforming capacity. As a result of a reconsideration of medium theory, the paper proposes a theoretical approach sensitive both to the social context of media technologies and to the properties of those technologies themselves.

    2014-05-07

    Telehealth has become an increasingly applied solution to delivering health care to rural and underserved areas by remote health care professionals. This study integrated social capital theory, social cognitive theory, and the technology acceptance model (TAM) to develop a comprehensive behavioral model for analyzing the relationships among social capital factors (social capital theory), technological factors (TAM), and system self-efficacy (social cognitive theory) in telehealth. The proposed framework was validated with 365 respondents from Nantou County, located in Central Taiwan. Structural equation modeling (SEM) was used to assess the causal relationships that were hypothesized in the proposed model. The finding indicates that elderly residents generally reported positive perceptions toward the telehealth system. Generally, the findings show that social capital factors (social trust, institutional trust, and social participation) significantly positively affect the technological factors (perceived ease of use and perceived usefulness respectively), which influenced usage intention. This study also confirmed that system self-efficacy was the salient antecedent of perceived ease of use. In addition, regarding the samples, the proposed model fitted considerably well. The proposed integrative psychosocial-technological model may serve as a theoretical basis for future research and can also offer empirical foresight to practitioners and researchers in the health departments of governments, hospitals, and rural communities.

  11. Technology and intellectual property strategy of a firm: A view through the commons theory lens

    Directory of Open Access Journals (Sweden)

    Mukundan Raghavan

    2013-12-01

    Full Text Available Strategy theory positions technology as a crucial resource of private value creation while commons theory provides governance structures pertinent to resource utilisation. The widening disconnect in the approach towards leveraging a resource and its governance increases the pressure on intellectual property that links strategy and commons. We discern in this work the existence of an implicit relationship between strategy and commons. Based on a multidisciplinary study of strategy, commons, and intellectual property theories, we propose patent pools in the form of semicommons as a strategic appropriation mechanism that balances technology strategy, IP strategy and commons in the pursuit of value creation.

  16. On the changeover timescales of technology transitions and induced efficiency changes: an overarching theory

    CERN Document Server

    Mercure, Jean-Francois

    2012-01-01

    This paper presents a general theory that aims at explaining timescales observed empirically in technology transitions and predicting those of future transitions. This framework is used further to derive a theory for exploring the dynamics that underlie the complex phenomenon of irreversible and path dependent price or policy induced efficiency changes. Technology transitions are known to follow patterns well described by logistic functions, which should more rigorously be modelled mathematically using the Lotka-Volterra family of differential equations, originally developed to described the population growth of competing species. The dynamic evolution of technology has also been described theoretically using evolutionary dynamics similar to that observed in nature. The theory presented here joins both approaches and presents a methodology for predicting changeover time constants in order to describe real systems of competing technologies. The problem of price or policy induced efficiency changes becomes natu...

  17. Technological paternalism: on how medicine has reformed ethics and how technology can refine moral theory.

    Science.gov (United States)

    Hofmann, Bjørn

    2003-07-01

    The objective of this article is to investigate ethical aspects of technology through the moral term "paternalism". The field of investigation is medicine. The reason for this is twofold. Firstly, "paternalism" has gained moral relevance through modern medicine, where physicians have been accused of behaving paternalistic and threatening patients' autonomy. Secondly, medicine is a brilliant area to scrutinise the evaluative aspects of technology. It is argued that paternalism is a morally relevant term for the ethics of technology, but that its traditional conception is not adequate to address the challenges of modern technology. A modification towards a "technological paternalism" is necessary. That is, "technological paternalism" is a fruitful term in the ethics of technology. Moreover, it is suited to point out the deficiencies of the traditional concept of paternalism and to reform and vitalise the conception of paternalism in ethics in order to handle the challenges of technology.

    2008-04-01

    To identify and describe the extent to which theory or theoretical frameworks informed the development and evaluation of decision support technologies (DSTs). The analysis was based on the decision technologies used in studies included in the Cochrane systematic review of patient decision aids for people facing health screening or treatment decisions. The assumption was made that DSTs evaluated by randomized controlled trials, and therefore included in the updated Cochrane review have been the most rigorously developed. Of the 50 DSTs evaluated only 17 (34%) were based on a theoretical framework. Amongst these, 11 decision-making theories were described but the extent to which theory informed the development, field-testing and evaluation of these interventions was highly variable between DSTs. The majority of the 17 DSTs that relied on a theory was not explicit about how theory had guided their design and evaluation. Many had superficial descriptions of the theory or theories involved. Furthermore, based on the analysis of those 17 DSTs, none had reported field-testing prior to evaluation. The use of decision-making theory in DST development is rare and poorly described. The lack of theoretical underpinning to the design and development of DSTs most likely reflects the early development stage of the DST field. The findings clearly indicate the need to give more attention to how the most important decision-making theories could be better used to guide the design of key decision support components and their modes of action.

  2. Theory and technology of preventing water from flooding roadways

    Institute of Scientific and Technical Information of China (English)

    CAO Sheng-gen; HOU Shi-song; LI Zhong-hua

    2008-01-01

    According to the principle of effective stress action of rock and soil, we established a mechanical model of water flooding into roadways, analyzed the constitutive relation of hydrodynamic pressure and contact pressure of rock and soil and discovered that the process of pre-grouting of a roadway curtain is a dynamically balancing process in which effective stress keeps gradually increasing and pore water pressure gradually declines. In such a grouting process, the initial water plugging effect is realized when the effective stress and total stress reaches equilibrium. A rigid-flexible packing layer is designed behind the brickwork to increase the effective stress and reduce pore water pressure in order to have a permanent water proof performance. This provides a theoretical basis for roadway driving and permanent water prevention. The monitoring and application results show that the initial and permanent waterproof theory has provided an effective method for roadway driving and making it waterproof.

    2008-01-01

    Web services use an emerging service-oriented architecture for distributed computing. Many organizations are either in the process of adopting web services technology or evaluating this option for incorporation into their enterprise information architectures. Implementation of this new technology requires careful assessment of the needs and capabilities of an organization to formulate adoption strategies. This paper presents a methodology for web services adoption based on technology adoption theory and business process analyses. The methodology suggests that strategies, business areas, and functions within an organization should be considered based on the existing organizational information technology status during the process of adopting web services to support the business needs and requirements.

    Marine geographic information system (MGIS) has great ability to deal with the spatio-temporal problems and has potential superiority when it is applied to oceanography. Using the feature extraction of oceanic phenomena as a case study, the functions of the MGIS are analyzed, and thus the position of MGIS in the oceanography is defined. Comparing the requirement of MGIS with that of the traditional GIS which has been developed in the terrestrial applications in the past four decades, the frame for the functions of MGIS is constructed. According to the established MGIS, some key technologies are discussed in detail with emphasis on the specialities which can distinguish the MGIS from the traditional GIS.

  5. Talking back to theory: the missed opportunities in learning technology research

    Directory of Open Access Journals (Sweden)

    Martin Oliver

    2011-12-01

    Full Text Available Research into learning technology has developed a reputation for being drivenby rhetoric about the revolutionary nature of new developments, for payingscant attention to theories that might be used to frame and inform research, andfor producing shallow analyses that do little to inform the practice of education.Although there is theoretically-informed research in learning technology, this isin the minority, and has been actively marginalised by calls for applied designwork. This limits opportunities to advance knowledge in the field. Using threeexamples, alternative ways to engage with theory are identified. The paper concludesby calling for greater engagement with theory, and the development of ascholarship of learning technology, in order to enrich practice within the fieldand demonstrate its relevance to other fields of work.

  8. Can interactive educational technologies support the link between ultrasound theory and practice via feedback mechanisms?

    Science.gov (United States)

    Dickson, Diane

    2015-05-01

    Linking theory to practice is an area of concern for ultrasound students, clinical mentors and academic staff. The link between theory and practice requires a robust clinical mentorship scheme in addition to careful curricula design considerations to improve student outcomes. The introduction of interactive technology in education provides ripe opportunity to improve feedback to students to support the link between theory and practice. A series of three interactive learning and teaching activities were designed and delivered to a PostGraduate Ultrasound cohort, after which, evaluation was performed to answer the research question: Which interactive technologies support the link between theory and practice through improved feedback mechanisms? An action research methodology was adopted involving an enquiry based literature review, planning, design and action process. Data were collected following action of three interactive teaching and learning sessions within the Medical Ultrasound cohort of 2013/2014 at Glasgow Caledonian University via a paper based questionnaire. A 100% response rate was achieved (n = 14). All three interactive learning and teaching sessions were considered with 100% highest point agreement to support the link between ultrasound theory and practice via feedback. Students found all three designed and facilitated sessions valuable and relevant to their learning, which in turn provided positive experiences which were perceived to support the link between theory and practice through feedback. These activities can be considered valuable in Postgraduate Ultrasound education.

This article argues that critical social theory, and the social and powerrelationships that it highlights, is central to the uncovering of this revelation. Asa result of a holistic, or totalising, analysis based upon the political economy oftechnology in education, a framework that enables educators to examine its educationalvalue is uncovered. Iterating and re-producing this framework works asa constant critique of educational practice within capitalism, and critiques deterministicor hegemonic views of technology-as-progress. As a result, this articleseeks to demonstrate how critical social theory might enable educators to analyselearning technology as historically situated, and thereby to use critique to revealand produce practical alternatives to sociocultural problems.

  11. Connectivism: Its Place in Theory-Informed Research and Innovation in Technology-Enabled Learning

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available The sociotechnical context for learning and education is dynamic and makes great demands on those trying to seize the opportunities presented by emerging technologies. The goal of this paper is to explore certain theories for our plans and actions in technology-enabled learning. Although presented as a successor to previous learning theories, connectivism alone is insufficient to inform learning and its support by technology in an internetworked world. However, because of its presence in massive open online courses (MOOCs, connectivism is influential in the practice of those who take these courses and who wish to apply it in teaching and learning. Thus connectivism is perceived as relevant by its practitioners but as lacking in rigour by its critics. Five scenarios of change are presented with frameworks of different theories to explore the variety of approaches educators can take in the contexts for change and their associated research/evaluation. I argue that the choice of which theories to use depends on the scope and purposes of the intervention, the funding available to resource the research/evaluation, and the experience and philosophical stances of the researchers/practitioners.

  12. Health, development and innovation: a contribution of the critical theory of technology to the discussion

    Directory of Open Access Journals (Sweden)

    Luis Eugenio Portela Fernandes de Souza

    Full Text Available Abstract: The relationships between health and socioeconomic development are diverse. These relationships find in the health economic complex a privileged ground for expression. The importance of health technologies increased exponentially since the middle of the 20th century, affecting health systems in terms of both, quality of care and economic aspects. In fact, the predominant model of care is based on fragmented, symptomatic therapy practices that encourages the use of products and services and promotes a passive participation of users rather than humanization of care. Overcoming this model requires changes in the health technology standards which, in turn, require changes in the technology standard of society. The critical theory of technology helps to understand the evolution of the industrial civilization. It enriches the discussion by suggesting the health economic complex be more sensibly adjusted to the requirements of comprehensive health care, and to inclusive and sustainable development.

    Full Text Available The purpose of the present study was to determine both the factors influencing student engagement and the role and influence of technology on student engagement. The study is important as it aimed at determining the views of students about student engagement and examining in detail the research data to be collected with two different data collection techniques. The present study was designed as a grounded theory study. The research sample included a total of 45 student teachers. Of all the participants, 25 of them participated in face-to-face Interviews, and 20 of them were asked to take part in written compositions. In conclusion, it was seen that the components constituting and influencing student engagement were found to be campus engagement and class engagement. It was found out that for most of the participating students, use of technology in class was not an indispensable factor for student engagement. In addition, an effective technology integration would not only contribute much to student engagement but also constitute an important way of increasing student engagement. Finally, it was seen that use of technology in instructional activities constituted an important factor for student engagement, when the findings obtained via the interviews and the written compositions were taken into consideration together

    Full Text Available The paper tries to develop a new approach to sustainable planning for the smart city. The relationship between new technologies and the urban system could be developed in a new way considering of the WET theory. The WET theory starts from the main components for establishment and the survival of the human settlements: Water, Energy and Technologies (WET. Considering this approach, the technology could be envisaged as a switch element for the biforcation that could be generated inside the process of management of the modern urban systems. From one end the technology can improve the use of renewable energies and promote a different way of use the energy inside the city. From the other end the technology can permit a huge structural  works that can drive the urban system towards a worst dimension causing permanent change inside the territory as a whole particularly at large scale. The paper propose a focus on the two mentioned possibilities considering  the best dimension, proposed by the DESERTEC project and the worst one prefigured by the South to North Water Diversion Project that is ready to start in China.

    be the most effective or most desirable way to use computer technology in literacy programs. This project is developing a series of instructional packages that are based on a different instructional model - authentic instruction. The instructional development model used to create these packages is also different. Instead of using the traditional five stage linear, sequential model based on behavioral learning theory, the project uses the recursive, reflective design and development model (R2D2) that is based on cognitive learning theory, particularly the social constructivism of Vygotsky, and an epistemology based on critical theory. Using alternative instructional and instructional development theories, the result of the summer faculty fellowship is LiteraCity, a multimedia adult literacy instructional package that is a simulation of finding and applying for a job. The program, which is about 120 megabytes, is distributed on CD-ROM.

    2005-03-01

    While reviews abound on theoretical topics in educational psychology, it is rare that we examine our field's instrumentation development, and what effects this has on educational psychology's evolution. To repair this gap, this paper investigates and reveals the implications of software technologies for researching and theorizing about core issues in educational psychology. From a set of approximately 1,500 articles published between 1999 and 2004, we sampled illustrative studies and organized them into four broad themes: (a) innovative ways to operationalize variables, (b) the changing nature of instructional interventions, (c) new fields of research in educational psychology, and (d) new constructs to be examined. In each area, we identify novel uses of these technologies and suggest how they may advance, and, in some instances, reshape theory and methodology. Overall, we demonstrate that software technologies hold significant potential to elaborate research in the field.

    Chinese medicine prescriptions are the wisdom outcomes of traditional Chinese medicine (TCM) clinical treatment determinations which based on differentiation of symptoms and signs. Chinese medicine prescriptions are also the basis of secondary exploitation of TCM. The study on prescription helps to understand the material basis of its efficacy, pharmacological mechanism, which is an important guarantee for the modernization of traditional Chinese medicine. Currently, there is not yet dissertation n the method and technology system of basic research on the prescription of Chinese medicine. This paper focuses on how to build an effective system of prescription research technology. Based on "component structure" theory, a technology system contained four-step method that "prescription analysis, the material basis screening, the material basis of analysis and optimization and verify" was proposed. The technology system analyzes the material basis of the three levels such as Chinese medicine pieces, constituents and the compounds which could respect the overall efficacy of Chinese medicine. Ideas of prescription optimization, remodeling are introduced into the system. The technology system is the combination of the existing research and associates with new techniques and methods, which used for explore the research thought suitable for material basis research and prescription remodeling. The system provides a reference for the secondary development of traditional Chinese medicine, and industrial upgrading.

    Full Text Available With the emergence of high speed wireless network technologies and the increasing market penetration of cell phones the global advertising industry’s interest in using this medium as a means of marketing communication is rising. However, in spite of the increasing number of companies investing in mobile marketing campaigns, there is, as yet, little academic research on this topic and the nature and implications of this channel are not yet understood fully.Mobile advertising refers to advertisements delivered through a mobile device in form of text message. Current research is considered as applied objectively and its methodology is descriptive-analytical. Research data is gathered through distribution of questionnaire among a sample of 578 Yazd university students. To study users' attitude and intention, Technology Acceptance Model and theory of reasoned action are applied for accepting mobile advertising. Also SPSS16 and Lisrel 850 softwares are used for data analysis and research models are compared according to goodness of fit indices. On the basis of Lisrel structural equation results, both aforementioned models of mobile advertising acceptance were well-fitted and it is proved that the theory of reasoned action was fitted better than Technology Acceptance Model.

  13. Towards a better understanding of people's responses to renewable energy technologies: Insights from Social Representations Theory.

    Science.gov (United States)

    Batel, Susana; Devine-Wright, Patrick

    2015-04-01

    In the past few years, social research has been examining what contributes to the attitude-behaviour gap in people's responses to large-scale renewable energy technologies. The NIMBY explanation for the gap has long dominated that area of research, but has also been criticised. Alternative proposals to NIMBY were advanced, but it is still evident that some of those maintain presuppositions of NIMBY and that this area of research needs more integration, namely at a theoretical level. In this paper we argue that to overcome those aspects it is relevant, first, to situate the promotion of renewable energy production as a social change process in today's societies, and, second, to therefore consider the socio-psychological aspects involved in people's responses to social change. We discuss specifically how the Theory of Social Representations may help us with that and contribute to a better understanding of people's responses to renewable energy technologies.

    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.

    2011-06-01

    Q-switched Short pulse laser has been widely applied in many fields, such as optical ranging, remote sensing, communications, nonlinear optics and spectroscopy etc. Q-switched Nd3+: YAG laser, with its high thermal conductivity and resistance to damage threshold, longer energy levels were generally used especially. Second harmonics generation was usually obtained through optical nonlinear effects in crystal. To the frequency doubling technology, poor conversion efficiency and multi-output frequency are the main problems. Researchers focus more on phase and group velocity matching induced by nonlinear effects, but pays less attention on theoretical modeling and numerical calculation of factors affecting frequency doubling of pulsed laser. In this article, nonlinear effects of double frequency crystals in Q-switched Nd3+: YAG laser was first analyzed in theory, then we deduced the relation expressions between factors affecting the efficiency of frequency doubling( thickness of frequency doubling crystal, cross section area of incident beam, power of the fundamental field, phase matching of incidence light)and double frequency efficiency. Secondly, taken KTP Crystal for example; numerical results and theirs' corresponding curves on these relation expressions was calculated and drawn with MATLAB software. These findings can be used for processing the specific requests of frequency doubling crystal. Finally, Theory modeling and numerical calculation were tested in experiment. The experiment results are in good agreement with those obtained in theory.

  19. Applying the Theory of the Firm to Examine a Technology Startup at the Investment Stage

    Directory of Open Access Journals (Sweden)

    Michael Ayukawa

    2012-05-01

    Full Text Available The investment stage of a new technology firm is when resources, opportunities, investors, and early customers first converge. Currently, technology entrepreneurs make many expensive mistakes. They invest in assets and develop capabilities that prove to have limited value. They take too long to discover and validate the product-market fit for their firms during the investment stage and run out of time and money. Understanding how theory can help entrepreneurs make decisions during the investment stage is important to accelerate new-firm formation and growth as well as to reduce the uncertainty of founders and stakeholders of technology firms. This article introduces a model developed to examine deal making during the investment stage of a new technology firm. It is an extension of a model of lateral firm scope proposed by Oliver Hart and Bengt Holmstrom. The extensions come from considering a technology firm as being both a deal-making entity and a pool of resources during the investment stage. A deal is the result of a decision the entrepreneur and others make to coordinate (i.e., work together to achieve a common objective. Benefits from a deal include cash profits for the firm and private benefits for the entrepreneur. This extended model is then applied to examine the author’s firm which is still in the investment stage. Application of the extended model to a real-life situation generated two important insights: i when private benefits include learning from experimentation, the number of deals increases and ii at the start of the investment stage, private benefits drive deal-making, whereas at the end of the investment stage, cash profits derived from asset ownership drive deal-making.

    In this paper we propose the theory of decomposition, methods, technologies, applications and implementation in Wol-fram Mathematica for the constructing the solutions of the sparse linear systems. One of the applications is the Sensor Location Problem for the symmetric graph in the case when split ratios of some arc flows can be zeros. The objective of that application is to minimize the number of sensors that are assigned to the nodes. We obtain a sparse system of linear algebraic equations and research its matrix rank. Sparse systems of these types appear in generalized network flow programming problems in the form of restrictions and can be characterized as systems with a large sparse sub-matrix representing the embedded network structure.

    The aim of this paper is to measure the effectiveness of the organizations Information and Communication Technology (ICT) from the point of view of the manager, using Item Response Theory (IRT). There is a need to verify the effectiveness of these organizations which are normally associated to complex, dynamic, and competitive environments. In academic literature, there is disagreement surrounding the concept of organizational effectiveness and its measurement. A construct was elaborated based on dimensions of effectiveness towards the construction of the items of the questionnaire which submitted to specialists for evaluation. It demonstrated itself to be viable in measuring organizational effectiveness of ICT companies under the point of view of a manager through using Two-Parameter Logistic Model (2PLM) of the IRT. This modeling permits us to evaluate the quality and property of each item placed within a single scale: items and respondents, which is not possible when using other similar tools.

    Whealin, Julia M; Kuhn, Eric; Pietrzak, Robert H

    2014-11-01

    Despite the availability of effective mental health interventions, the vast majority of veterans with a mental disorder underutilize psychological services. Contemporary research has revealed that several factors such as low education, stigma, stoicism, lack of knowledge, and negative beliefs about mental health services are associated with veterans' underutilization of services. In this article, the authors provide an overview of factors that affect symptomatic veterans' decisions about whether to seek mental health services. Second, they describe the theory of planned behavior (Ajzen & Fishbein, 1980), a useful model for understanding mental health care seeking that can inform the development of technology-based interventions designed to increase veterans' willingness to seek psychological services. Third, the authors describe the development of Considering Professional Help, a personalized web-based tool developed by the Department of Veterans Affairs, which has been designed to promote mental health care seeking in veterans with mental health problems.

    This multi-authored textbook addresses graduate students with a background in physics, mathematics or computer science. No research experience is necessary. Consequently, rather than comprehensively reviewing the vast body of knowledge and literature gathered in the past twenty years, this book concentrates on a number of carefully selected aspects of quantum information theory and technology. Given the highly interdisciplinary nature of the subject, the multi-authored approach brings together different points of view from various renowned experts, providing a coherent picture of the subject matter. The book consists of ten chapters and includes examples, problems, and exercises. The first five present the mathematical tools required for a full comprehension of various aspects of quantum mechanics, classical information, and coding theory. Chapter 6 deals with the manipulation and transmission of information in the quantum realm. Chapters 7 and 8 discuss experimental implementations of quantum information ideas using photons and atoms. Finally, chapters 9 and 10 address ground-breaking applications in cryptography and computation. (orig.)

    Full Text Available Given the significant requirements for transforming and promoting the process industry, we present the major limitations of current petrochemical enterprises, including limitations in decision-making, production operation, efficiency and security, information integration, and so forth. To promote a vision of the process industry with efficient, green, and smart production, modern information technology should be utilized throughout the entire optimization process for production, management, and marketing. To focus on smart equipment in manufacturing processes, as well as on the adaptive intelligent optimization of the manufacturing process, operating mode, and supply chain management, we put forward several key scientific problems in engineering in a demand-driven and application-oriented manner, namely: ① intelligent sensing and integration of all process information, including production and management information; ② collaborative decision-making in the supply chain, industry chain, and value chain, driven by knowledge; ③ cooperative control and optimization of plant-wide production processes via human-cyber-physical interaction; and ④ life-cycle assessments for safety and environmental footprint monitoring, in addition to tracing analysis and risk control. In order to solve these limitations and core scientific problems, we further present fundamental theories and key technologies for smart and optimal manufacturing in the process industry. Although this paper discusses the process industry in China, the conclusions in this paper can be extended to the process industry around the world.

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

    The relationships between health and socioeconomic development are diverse. These relationships find in the health economic complex a privileged ground for expression. The importance of health technologies increased exponentially since the middle of the 20th century, affecting health systems in terms of both, quality of care and economic aspects. In fact, the predominant model of care is based on fragmented, symptomatic therapy practices that encourages the use of products and services and promotes a passive participation of users rather than humanization of care. Overcoming this model requires changes in the health technology standards which, in turn, require changes in the technology standard of society. The critical theory of technology helps to understand the evolution of the industrial civilization. It enriches the discussion by suggesting the health economic complex be more sensibly adjusted to the requirements of comprehensive health care, and to inclusive and sustainable development. Resumo: As relações entre a saúde e o desenvolvimento socioeconômico são múltiplas. Essas relações têm o complexo econômico da saúde como o espaço privilegiado de sua expressão. A importância das tecnologias de saúde aumentou exponencialmente desde meados do século XX, com efeitos sobre os sistemas de saúde, tanto em qualidade da atenção, quanto em aspectos econômicos. Na realidade, predomina um modelo de atenção caracterizado por práticas fragmentadas, que enfatizam tratamentos sintomáticos, estimulam o consumismo de produtos e serviços e promovem, ao invés da humanização, uma participação passiva dos usuários. A superação desse modelo passa pela mudança do padrão tecnológico da saúde, que, por sua vez, exige a transformação do padrão tecnológico da sociedade. A teoria crítica da tecnologia ajuda a compreender a evolução da civilização industrial. Enriquece o debate, sugerindo uma conformação do complexo econômico da saúde mais

  14. Actor-Network Theory and its role in understanding the implementation of information technology developments in healthcare.

    2010-11-01

    Actor-Network Theory (ANT) is an increasingly influential, but still deeply contested, approach to understand humans and their interactions with inanimate objects. We argue that health services research, and in particular evaluations of complex IT systems in health service organisations, may benefit from being informed by Actor-Network Theory perspectives. Despite some limitations, an Actor-Network Theory-based approach is conceptually useful in helping to appreciate the complexity of reality (including the complexity of organisations) and the active role of technology in this context. This can prove helpful in understanding how social effects are generated as a result of associations between different actors in a network. Of central importance in this respect is that Actor-Network Theory provides a lens through which to view the role of technology in shaping social processes. Attention to this shaping role can contribute to a more holistic appreciation of the complexity of technology introduction in healthcare settings. It can also prove practically useful in providing a theoretically informed approach to sampling (by drawing on informants that are related to the technology in question) and analysis (by providing a conceptual tool and vocabulary that can form the basis for interpretations). We draw on existing empirical work in this area and our ongoing work investigating the integration of electronic health record systems introduced as part of England's National Programme for Information Technology to illustrate salient points. Actor-Network Theory needs to be used pragmatically with an appreciation of its shortcomings. Our experiences suggest it can be helpful in investigating technology implementations in healthcare settings.

    Stress in office environments is a big concern, often leading to burn-out. New technologies are emerging, such as easily available sensors, contextual reasoning, and electronic coaching (e-coaching) apps. In the Smart Reasoning for Well-being at Home and at Work (SWELL) project, we explore the potential of using such new pervasive technologies to provide support for the self-management of well-being, with a focus on individuals' stress-coping. Ideally, these new pervasive systems should be grounded in existing work stress and intervention theory. However, there is a large diversity of theories and they hardly provide explicit directions for technology design. The aim of this paper is to present a comprehensive and concise framework that can be used to design pervasive technologies that support knowledge workers to decrease stress. Based on a literature study we identify concepts relevant to well-being at work and select different work stress models to find causes of work stress that can be addressed. From a technical perspective, we then describe how sensors can be used to infer stress and the context in which it appears, and use intervention theory to further specify interventions that can be provided by means of pervasive technology. The resulting general framework relates several relevant theories: we relate "engagement and burn-out" to "stress", and describe how relevant aspects can be quantified by means of sensors. We also outline underlying causes of work stress and how these can be addressed with interventions, in particular utilizing new technologies integrating behavioral change theory. Based upon this framework we were able to derive requirements for our case study, the pervasive SWELL system, and we implemented two prototypes. Small-scale user studies proved the value of the derived technology-supported interventions. The presented framework can be used to systematically develop theory-based technology-supported interventions to address work stress. In

    Binti Shamsuddin, Norsila

    Technology advancement and development in a higher learning institution is a chance for students to be motivated to learn in depth in the information technology areas. Students should take hold of the opportunity to blend their skills towards these technologies as preparation for them when graduating. The curriculum itself can rise up the students' interest and persuade them to be directly involved in the evolvement of the technology. The aim of this study is to see how deep is the students' involvement as well as their acceptance towards the adoption of the technology used in Computer Graphics and Image Processing subjects. The study will be towards the Bachelor students in Faculty of Industrial Information Technology (FIIT), Universiti Industri Selangor (UNISEL); Bac. In Multimedia Industry, BSc. Computer Science and BSc. Computer Science (Software Engineering). This study utilizes the new Unified Theory of Acceptance and Use of Technology (UTAUT) to further validate the model and enhance our understanding of the adoption of Computer Graphics and Image Processing Technologies. Four (4) out of eight (8) independent factors in UTAUT will be studied towards the dependent factor.

  19. On the application of motivation theory to human factors/ergonomics: motivational design principles for human-technology interaction.

    Science.gov (United States)

    Szalma, James L

    2014-12-01

    Motivation is a driving force in human-technology interaction. This paper represents an effort to (a) describe a theoretical model of motivation in human technology interaction, (b) provide design principles and guidelines based on this theory, and (c) describe a sequence of steps for the. evaluation of motivational factors in human-technology interaction. Motivation theory has been relatively neglected in human factors/ergonomics (HF/E). In both research and practice, the (implicit) assumption has been that the operator is already motivated or that motivation is an organizational concern and beyond the purview of HF/E. However, technology can induce task-related boredom (e.g., automation) that can be stressful and also increase system vulnerability to performance failures. A theoretical model of motivation in human-technology interaction is proposed, based on extension of the self-determination theory of motivation to HF/E. This model provides the basis for both future research and for development of practical recommendations for design. General principles and guidelines for motivational design are described as well as a sequence of steps for the design process. Human motivation is an important concern for HF/E research and practice. Procedures in the design of both simple and complex technologies can, and should, include the evaluation of motivational characteristics of the task, interface, or system. In addition, researchers should investigate these factors in specific human-technology domains. The theory, principles, and guidelines described here can be incorporated into existing techniques for task analysis and for interface and system design.

    The agricultural energy consumption per unit of GDP is selected as an indicator for measuring the development level of low-carbon agriculture. Using gray relational theory, I analyze the relationship between development level of agricultural science and technology and development level of low-carbon agriculture in China. The results show that the correlation between the two is prominent; the number of agricultural science and technology talents, the number of agricultural science and technology patents, and the number of agricultural science and technology input are three major factors influencing the development of low-carbon agriculture. On this basis, I propose to take further effective measures, and put forth corresponding recommendations, in order to improve the level of agricultural science and technology.

    Rich-media describes a broad range of digital interactive media that is increasingly used in the Internet and also in the support of education. Last year, a special pilot audiovisual lecture room was built as a part of the MERLINGO (MEdia-rich Repository of LearnING Objects) project solution. It contains all the elements of the modern lecture room determined for the implementation of presentation recordings based on the rich-media technologies and their publication online or on-demand featuring the access of all its elements in the automated mode including automatic editing. Property-preserving Petri net process algebras (PPPA) were designed for the specification and verification of the Petri net processes. PPPA does not need to verify the composition of the Petri net processes because all their algebraic operators preserve the specified set of the properties. These original PPPA are significantly generalized for the newly introduced class of the SNT Petri process and agent nets in this paper. The PLACE-SUBST and ASYNC-PROC algebraic operators are defined for this class of Petri nets and their chosen properties are proved. The SNT Petri process and agent nets theory were significantly applied at the design, verification, and implementation of the programming system ensuring the pilot audiovisual lecture room functionality.

    2014-01-01

    This paper proposes a Chinese character teaching system by using the Chinese character structure theory and the 2D contour morphing technology. This system, including the offline phase and the online phase, automatically generates animation for the same Chinese character from different writing stages to intuitively show the evolution of shape and topology in the process of Chinese characters teaching. The offline phase builds the component models database for the same script and the components correspondence database for different scripts. Given two or several different scripts of the same Chinese character, the online phase firstly divides the Chinese characters into components by using the process of Chinese character parsing, and then generates the evolution animation by using the process of Chinese character morphing. Finally, two writing stages of Chinese characters, i.e., seal script and clerical script, are used in experiment to show the ability of the system. The result of the user experience study shows that the system can successfully guide students to improve the learning of Chinese characters. And the users agree that the system is interesting and can motivate them to learn. PMID:24978171

Therefore, in order to improve the ability to disaster prevention and reduction and enhance the monitoring and warning on the debris flow, using the conventional meteorological data, satellite and radar data, the massive mudslide in Zhouqu, Gansu on 8 August 2010 studied. The results show that on the background of pre-drought and low soil moisture, the heavy precipitation caused the heaviest massive mudslide. The reasons why the heavy precipitation occured were that invasion of on the cold advection combined with the shear line on 700 hPa and that weak cold air diffused triggered off releasing unsteady energy. Extremely non-uniform precipitation was caused by a series of y meso-scale cyclone which were formed by terrain and so on. The corresponding relationship between heavy precipitation and brightness temperature was very good, but the brightness temperature was not the unique factors led to heavy precipitation. For γ me-soscale vortex, radial velocity was a good indicator since rotary speed can indicate the cyclone intensity. There was a good positive correlation between precipitation and γ mesoscale cyclone. According to the topographic feature on edge of the Tibetan

    Care may be compromised for hospitalized technology-dependent children if nurses do not communicate with parents to include their knowledge in the child's plan of care. A qualitative study using grounded theory methodology was undertaken to identify parental perceptions and experiences of communication with nurses. The Theory of Shared Communication was the result of this study and includes questioning, listening, explaining, advocating, verifying understanding and negotiating roles to achieve the outcome of mutual understanding of the child's plan of care. Nurses should be aware of parent perceptions about communication when working with families to optimize the care they provide.

    2013-04-01

    Full Text Available The Depot-Logistic Information Management System (DLIMS is aimed to provide the Air Force logistics staff of all sectors with an information technology platform for convenience of management, supervision, aircraft maintenance, along with supply operations. The DLIMS in Taiwan has been established for more than 10 years. However, it has not been evaluated for its effectiveness. This study integrates service quality into Wixom and Todd [1] model to evaluate the effectiveness of the DLIMS. A survey of 273 users of DLIMS was conducted to validate the proposed model. The research results show that the overall goodness-of-fit indices indicate a reasonable fit of the model and data. This study emphasizes the importance of integration of satisfaction theory and technology acceptance theory to comprehensively illustrate the effectiveness of DLIMS. The integrative viewpoint implies that DLIMS is not only a logistic information system but also a service provider to the Air Force. Accordingly, the professional staff officers IS department, logistics sectors and headquarters should value simultaneously object-based functions and service quality, in order to improve users’ satisfaction, which in turn can promote users’ behavioral beliefs and usage intention. The findings can be a reference for the Air Force logistics sectors to make policies as well as be a basis for evaluation of success and acceptance of military-related information system.

  16. Investigating the Perceptions of Care Coordinators on Using Behavior Theory-Based Mobile Health Technology With Medicaid Populations: A Grounded Theory Study.

    Medicaid populations are less engaged in their health care than the rest of the population, translating to worse health outcomes and increased health care costs. Since theory-based mobile health (mHealth) interventions have been shown to increase patient engagement, mobile phones may be an optimal strategy to reach this population. With increased development of theory-based mHealth technology, these interventions must now be evaluated with these medically underserved populations in a real-world setting. The aim of our study was to investigate care coordinators' perceived value of using a health behavior theory-based mHealth platform with Medicaid clients. In particular, attention was paid to the perceived impact on patient engagement. This research was conducted using the patient-provider text messaging (short message service, SMS) platform, Sense Health (now Wellpass), which integrates the transtheoretical model (TTM), also called the stages of change model; social cognitive theory (SCT); supportive accountability; and motivational interviewing (MI). Interviews based in grounded theory methodology were conducted with 10 care managers to understand perceptions of the relationship between mHealth and patient engagement. The interviews with care managers yielded a foundation for a grounded theory model, presenting themes that suggested 4 intertwined correlative relationships revolving around patient engagement: (1) A text messaging (short message service, SMS) platform supplements the client-care manager dynamic, which is grounded in high quality, reciprocal-communication to increase patient engagement; (2) Texting enhances the relationship between literacy and access to care for Medicaid patients, increasing low-literacy patients' agency to access services; (3) Texting enhances communication, providing care managers with a new means to support their clients; and (4) Reminders augment client accountability, leading to both increased motivation and readiness to change

    1999-01-01

    Full Text Available For the past two years the author has been teaching economics (History of Economic Thought and Economic Development at the tertiary level via the Internet and computer-mediation. This is done primarily for students who are unable or who do not wish to attend classes on campus, but desire an education as good, if not better, as the campus based enterprise. This paper provides a reflective analysis of the theoretical content of that practice. Teaching ‘online’ is a vastly different enterprise than face-to-face exercises, thereby demanding a revaluation of one’s pedagogical theory and praxis. In The German Ideology, Marx and Engels articulated their claim that historically dominant classes embody their ideas in essential forms, representing them as universally valid. It is within this framework that we begin to examine what it means to "know" in economics. How knowledge is legitimated in universities continues to be under-theorised, particularly with regard to electronic transmission. The mechanism of transmission of particular concern here is that which is computer-mediated. Landow represents hypertext as the latest flowering in a long march of democratic processes originating in the displacement of Platonic authority by the lesser authority of the written word. It is argued here that the determinism of the "progressive narrative" within and around the "hypertext revolution" deserves careful scrutiny, particularly in its application to pedagogy. Pedagogical artefacts, such as computers, mediate the transmission of ideas. The question "how does this happen?" relates to the complexity of theorizing the relationship between the educational process and the social relations of capitalist social formations. Over two decades ago, Bowles and Gintis attempted a Marxist understanding of the nature of this relationship. In their conception, pedagogical mechanisms were seen to operate in a fairly deterministic way to mirror and model the norms and values

  20. The demographic effects of technological change and capitalist transformation--a re-interpretation of the demographic transition theory.

    Maitra, P

    1992-06-01

    The interrelationship between demographic transition, capitalist transformation, and technological change in the 2 contrasting cases of the UK and India is explored. In the UK, technological change evolved from the extensive to the intensive phase, while technological change was introduced in India from the UK and other developed economies. The Demographic Transition Model is re-examined for these cases while the extensive and intensive phases of technological change with their effects on labor demand and consequent effects on fertility rate are analyzed. Changes in economic structure, demography, and factor pricing systems are presented as indicators of capitalist transformation of an economy. At the onset of capitalist transformation, population growth tends to decline as a result of increasing demand for labor in productive activities. Accordingly, the pattern of population growth depends upon the growth of demand for labor in productive activities which in turn depends upon the nature of the source of technological change; Demographic Transition theory ignores this point. Debate remains over whether imported technology, once reaching maturity, may effect capitalist transformation of economies toward true integrated development.

    2010-12-01

    Full Text Available In Part 1 of a two-part article series, the authors reported on the shortcomings of existing teacher preparation practice concerning technology and teacher education and described the theoretical grounding behind one model for integrating technology intoteacher preparation (Duran & Fossum, 2010. Part 2 here reports on a research project that applied the model at a major university in the U.S. Over a three-year period involving seven cohort groups, 246 educators participated in the study, which combined both quantitative and qualitative data collection and analysis. Findings indicate that over the course of the program, project participants significantly improved their confidence and competence in technology literacy as well as integration of information technology intothe teaching and learning process. The study demonstrates that an approach to professional development that encourages networking, mutual learning, and sharing of strategies and resources among K-16 educators can be effective in improving technology integration in teacher preparation.

    2014-06-01

    Full Text Available The comparative analysis of theoretical bases and the practice of moral education technologies implementation in Polish and Ukrainian pedagogy has been made. There has been stated that moral education technology in Ukrainian pedagogical science can be interpreted as a moral education system, the constituent parts of which are the following: aims, the content of the technology, procedural components (forms, methods and means of interaction between a teacher and pupils, diagnostic tools, and the result that meets the defined aim. Moral education technology can also be interpreted as modern means of moral education; as a project (model of moral education process; as a branch of scientific knowledge; as any educational innovation. Moral education technology is interpreted as a strategy of moral education in Polish educational science. Three strategies of moral education - forming, searching and open - have been described. There have been determined that in Polish and Ukrainian pedagogical sciences the technology of moral education is considered to be a wider concept than the method and methodology. The technology of moral education is interpreted as a branch of scientific knowledge about the process, bases, techniques, methods and means of moral education, as well as conditions of its effectiveness, which ensure educational skills. Criteria of moral education technologies have been determined. The importance of educational diagnostics to the development of moral education technologies has been shown. The causes of the weak development of moral education technologies such as the lack of the accordance to the diagnostics criterion, an intuitive approach to solving moral education problems, complication of their solution have been cleared up. Prospects of using positive ideas in modern educational and moral environment have been revealed.

    Vadali, Srinivas R.; Carter, Michael T.

    1994-01-01

    The Phillips Laboratory at the Edwards Air Force Base has developed the Advanced Space Structures Technology Research Experiment (ASTREX) facility to serve as a testbed for demonstrating the applicability of proven theories to the challenges of spacecraft maneuvers and structural control. This report describes the work performed on the ASTREX test article by Texas A&M University under contract NAS119373 as a part of the Control-Structure Interaction (CSI) Guest Investigator Program. The focus of this work is on maneuvering the ASTREX test article with compressed air thrusters that can be throttled, while attenuating structural excitation. The theoretical foundation for designing the near minimum-time thrust commands is based on the generation of smooth, parameterized optimal open-loop control profiles, and the determination of control laws for final position regulation and tracking using Lyapunov stability theory. Details of the theory, mathematical modeling, model updating, and compensation for the presence of 'real world' effects are described and the experimental results are presented. The results show an excellent match between theory and experiments.

  16. Understanding the Adoption Process of National Security Technology: An Integration of Diffusion of Innovations and Volitional Behavior Theories.

    Iles, Irina A; Egnoto, Michael J; Fisher Liu, Brooke; Ackerman, Gary; Roberts, Holly; Smith, Daniel

    2017-03-01

    After the 9/11 terrorist attacks, the U.S. government initiated several national security technology adoption programs. The American public, however, has been skeptical about these initiatives and adoption of national security technologies has been mandated, rather than voluntary. We propose and test a voluntary behavioral intention formation model for the adoption of one type of new security technology: portable radiation detectors. Portable radiation detectors are an efficient way of detecting radiological and nuclear threats and could potentially prevent loss of life and damage to individuals' health. However, their functioning requires that a critical mass of individuals use them on a daily basis. We combine the explanatory advantages of diffusion of innovation with the predictive power of two volitional behavior frameworks: the theory of reasoned action and the health belief model. A large sample survey (N = 1,482) investigated the influence of factors identified in previous diffusion of innovation research on portable radiation detector adoption intention. Results indicated that nonfinancial incentives, as opposed to financial incentives, should be emphasized in persuasive communications aimed at fostering adoption. The research provides a new integration of diffusion of innovation elements with determinants of volitional behavior from persuasion literature, and offers recommendations on effective communication about new security technologies to motivate public adoption and enhance national safety. © 2017 Society for Risk Analysis.

  17. Engineering Philosophy: Theories of Technology, German Idealism, and Social Order in High-Industrial Germany.

    Science.gov (United States)

    Voskuhl, Adelheid

    During the so-called "Second Industrial Revolution," engineers were constituting themselves as a new social and professional group, and found themselves in often fierce competition with existing elites-the military, the nobility, and educated bourgeois mandarins-whose roots went back to medieval and early modern pre-industrial social orders. During that same time, engineers also discovered the discipline of philosophy: as a means to express their intellectual and social agendas, and to theorize technology and its relationship to art, history, culture, philosophy, and the state. This article analyzes engineers' own philosophical writings about technology as well as the institutions in which they composed them in 1910s and 1920s Germany. It emphasizes engineers' contributions to well-known discourses founded by canonical philosophers, the role of preindustrial economies and their imagination in such philosophies, and the role of both the history and the philosophy of technology in engineers' desire for upward social mobility.

    Directory of Open Access Journals (Sweden)

    Melanie Swan

    2010-02-01

    Full Text Available Information optimization is a centerpiece phenomenon in the universe. It develops from simplicity, then continuously breaks symmetry and cycles through instability to progress to increasingly dense nodes of complexity and diversity. Intelligence has arisen as the information optimization node with the greatest complexity. A contemporary imbalance is presented in that exponentially growing technology could be poised as a potential sole successor to human intelligence. A complex dynamical system is emerging in response, the engineering of life into technology. Numerous network elements are developing which could self-organize into the next node of symmetry, a phase transition in intelligence.

  20. Optimization Methods From Theory to Design Scientific and Technological Aspects in Mechanics

    CERN Document Server

    Cavazzuti, Marco

    2013-01-01

    This book is about optimization techniques and is subdivided into two parts. In the first part a wide overview on optimization theory is presented. Optimization is presented as being composed of five topics, namely: design of experiment, response surface modeling, deterministic optimization, stochastic optimization, and robust engineering design. Each chapter, after presenting the main techniques for each part, draws application oriented conclusions including didactic examples. In the second part some applications are presented to guide the reader through the process of setting up a few optimization exercises, analyzing critically the choices which are made step by step, and showing how the different topics that constitute the optimization theory can be used jointly in an optimization process. The applications which are presented are mainly in the field of thermodynamics and fluid dynamics due to the author's background.

  1. Density functional theory and beyond-opportunities for quantum methods in materials modeling semiconductor technology.

    Science.gov (United States)

    Shankar, Sadasivan; Simka, Harsono; Haverty, Michael

    2008-02-13

    In the semiconductor industry, the use of new materials has been increasing with the advent of nanotechnology. As critical dimensions decrease, and the number of materials increases, the interactions between heterogeneous materials themselves and processing increase in complexity. Traditionally, applications of ab initio techniques are confined to electronic structure and band gap calculations of bulk materials, which are then used in coarse-grained models such as mesoscopic and continuum models. Density functional theory is the most widely used ab initio technique that was successfully extended to several applications. This paper illustrates applications of density functional theory to semiconductor processes and proposes further opportunities for use of such techniques in process development.

  2. Facilitators and barriers to adopting robotic-assisted surgery: contextualizing the unified theory of acceptance and use of technology.

    Directory of Open Access Journals (Sweden)

    Christine Benmessaoud

    Full Text Available Robotic-assisted surgical techniques are not yet well established among surgeon practice groups beyond a few surgical subspecialties. To help identify the facilitators and barriers to their adoption, this belief-elicitation study contextualized and supplemented constructs of the unified theory of acceptance and use of technology (UTAUT in robotic-assisted surgery. Semi-structured individual interviews were conducted with 21 surgeons comprising two groups: users and nonusers. The main facilitators to adoption were Perceived Usefulness and Facilitating Conditions among both users and nonusers, followed by Attitude Toward Using Technology among users and Extrinsic Motivation among nonusers. The three main barriers to adoption for both users and nonusers were Perceived Ease of Use and Complexity, Perceived Usefulness, and Perceived Behavioral Control. This study's findings can assist surgeons, hospital and medical school administrators, and other policy makers on the proper adoption of robotic-assisted surgery and can guide future research on the development of theories and framing of hypotheses.

  2. Explaining Work Exhaustion From a Coping Theory Perspective: Roles of Techno-Stressors and Technology-Specific Coping Strategies.

    Science.gov (United States)

    Gaudioso, Fulvio; Turel, Ofir; Galimberti, Carlo

    2015-01-01

    The purpose of this study is to theoretically develop and empirically examine a general coping theory model which explicates the indirect effects of key job-related techno-stressors on job exhaustion. Through this study, we show that techno-stress creators are detrimental to employee well-being and should be treated accordingly. Specifically, we first argue that key techno-stress creators on the job, namely techno-invasion and techno-overload, drive unpleasant states such as work-family conflict and distress. Next, we rely on general coping theory and argue that people respond to these states differently, but with both adaptive and maladaptive technology-specific coping strategies. Adaptive coping behaviors are argued to ultimately reduce work exhaustion, and maladaptive coping strategies are argued to increase it. The proposed model was tested and validated with structural equation modeling techniques applied to self-reported data obtained from a sample of 242 employees of a large organization in the United States. Implications for theory and practice are discussed.

    Winter, Sandra J; Sheats, Jylana L; King, Abby C

    2016-01-01

    This review examined the use of health behavior change techniques and theory in technology-enabled interventions targeting risk factors and indicators for cardiovascular disease (CVD) prevention and treatment. Articles targeting physical activity, weight loss, smoking cessation and management of hypertension, lipids and blood glucose were sourced from PubMed (November 2010-2015) and coded for use of 1) technology, 2) health behavior change techniques (using the CALO-RE taxonomy), and 3) health behavior theories. Of the 984 articles reviewed, 304 were relevant (240=intervention, 64=review). Twenty-two different technologies were used (M=1.45, SD=+/-0.719). The most frequently used behavior change techniques were self-monitoring and feedback on performance (M=5.4, SD=+/-2.9). Half (52%) of the intervention studies named a theory/model - most frequently Social Cognitive Theory, the Trans-theoretical Model, and the Theory of Planned Behavior/Reasoned Action. To optimize technology-enabled interventions targeting CVD risk factors, integrated behavior change theories that incorporate a variety of evidence-based health behavior change techniques are needed.

    In order to solve the problem of high dust concentration caused by the rapid advance of coal roadways using the ABM20 development machine, a method suitable for the rapid advance of coal roadways in China was proposed. By using the mathematic model method to contrast the wind current field and dust field of the drivage face under different drivage velocities, an optimized drivage velocity of the fully-mechanized development machine was obtained. The theories were tested in an industry experiment. Analysis of the data indicates that the proposed enclosure dust-laying system can significantly lower the dust concentration at the heading face. It also has some advantages in accomplishing the effective advance of coal mines. 9 refs., 5 figs.

    CERN Document Server

    Dowden, John

    2009-01-01

    The purpose of the book is to show how general principles can be used to obtain insight into laser processes. The principles used may come from fundamental physical theory or from direct observation of experimental results, but an understanding of the general characteristics of the behaviour of a process is essential for intelligent investigation and implementation, whether the approach is experimental, observational, numerical or analytical. The last two have a special value since the associated costs can be relatively low and may be used as a starting point for more expensive techniques. The construction of simple models whose underlying principles are easy to see is therefore of special value, and an understanding of their strengths and limitations is essential. The applications considered in detail are cutting, keyhole welding, drilling, arc and hybrid laser-arc welding, hardening, cladding, forming and cutting, but the general principles have a very wide application; metallurgical aspects are considered,...

    2016-01-01

    This chapter studies the bidirectional causal interactions between curiosity and learning and discusses how understanding these interactions can be leveraged in educational technology applications. First, we review recent results showing how state curiosity, and more generally the experience of novelty and surprise, can enhance learning and memory retention. Then, we discuss how psychology and neuroscience have conceptualized curiosity and intrinsic motivation, studying how the brain can be intrinsically rewarded by novelty, complexity, or other measures of information. We explain how the framework of computational reinforcement learning can be used to model such mechanisms of curiosity. Then, we discuss the learning progress (LP) hypothesis, which posits a positive feedback loop between curiosity and learning. We outline experiments with robots that show how LP-driven attention and exploration can self-organize a developmental learning curriculum scaffolding efficient acquisition of multiple skills/tasks. Finally, we discuss recent work exploiting these conceptual and computational models in educational technologies, showing in particular how intelligent tutoring systems can be designed to foster curiosity and learning. © 2016 Elsevier B.V.

    Based on the theory of multiple-scale integrated assessment of societal and ecosystem metabolism (MuSIASEM), a comprehensive evaluation was made on the human activity time, exosomatic energy input, and added value of Dalian Economic and Technological Development Zone in 2000-2007. During the study period, the life quality of local citizens increased year after year, while the agricultural industry dwindled. Manufacturing industry was still the main pillar industry, but its energy consumption was greater. Service industry was at its early stage, falling behind manufacturing industry. The exosomatic metabolic level of the whole zone and its various industries had an obvious increase, and the energy intensity decreased continuously. With the fact that both the human activity time and the exosomatic energy input had a ceaseless decrease, the economic added value increased steadily, and the zone was under its way towards sustainable development.

    Full Text Available The purpose of this article is to apply the methodology to structure the decision problem and select an appropriate LOR architecture. This reflected in the need to invest and improve the technology for educational organizations. Selecting an appropriate infrastructure for LOR is usually a complex decision, because it has conflicting attributes. In situations of uncertainty, multi-attribute utility theory (MAUT assists in selecting the best alternative according to criteria established by the decision maker. Results demonstrated that the choice of indexing and distributing LOR (A4 is less sensitive to changes and has greater utility. According to the analysis, A4 is the option most suitable for deploying IT infrastructure in the case of application. Researchers and professional managers can assess the types of ROA architecture and replicate this decision model to find similar results.

    Full Text Available The objective of this study is to examine the relationship between awareness and adoption of a Goods and Services Tax (GST application system using the Unified Theory of Acceptance and Use of Technology (UTAUT model at the organizational level. Questionnaires were distributed among employees of organizations that will be affected by the introduction of the Goods and Services Tax. Data were analyzed using the Partial Least Square (PLS approach. The results showed that for non adopters, GST awareness is positively related to all of the UTAUT factors except for facilitating conditions. This study was conducted before the Goods and Services Tax is implemented in Malaysia and thus, this study did not determine if these organizations had actually adopted the software. This study observes the adoption of a GST application system, a type of taxation software, which assists firms to comply to the Goods and Services Tax. This study suggests that from the perspective of non adopters, awareness is crucial to the adoption of a new Information Technology system in an organization.

    Optical time division multiplexing (OTDM) is one of thepromisinig ways for the future high-speed optical fiber communication networks. All-optical switch is, being one of the core technologies of OTDM systems and networks, crucial to realize the various signal processes including time-division demultiplexing, packet switching, all-optical regenerating and so on. This thesis mainly studies various all-optical switch technologies and their utilization in the fields of all-optical signal processings in the OTDM systems and networks. The main jobs are listed as follows.(1) A novel all-optical ultrafast demultiplexing scheme using the soliton self-trapping effect in birefringent fiber is proposed.(2) The demultiplexing performance of the Nonlinear Optical Loop Mirror(NOLM) is thoroughly analyzed and its optimization is further discussed.(3) The performance analysis and the configuration optimization of the all-optical switches based on the Semiconductor Optical Amplifier(SOA) are systematically presented. The speed limitation of the all-optical SOA switches induced by the fast gain depletion of SOA is discussed. Besides, a novel SOA switch is proposed, which adopts the asymmetric Mach-Zehnder Interferometer configuration.(4) The 8×2\\^5 Gb/s OTDM experimental transmission system along 105 km standard fiber is realized using the NOLM demultiplexer.(5) The NOLM switch is used to realize the all-optical 3R regeneration of 2\\^5 Gb/s Return-to-Zero signal.(6) The feasibility and limitation of the all-optical SOA packet switch is discussed. And a developed MZI configuration of SOA packet switch is further shown to improve the packet switching performance. Finally, an all-optical packet dropping node suitable in the networks with ring or bus configuration and an all-optical packet switching node in the ShuffleNet networks are proposed to show the feasibility of all-optical packet switching through combining the all-optical switches and the reasonable logic decisions.

  7. The theory of multiple stupidities: education, technology and organisation in Arabia.

    2017-05-16

    Traditional perspectives have envisaged intelligence as one entity dominated by a single set of abilities (i.e. cognitive abilities), whereas modern perspectives have defined intelligence in various shapes (e.g. linguistic, musical and interpersonal intelligences). By the same token, traditional perspectives have examined stupidity as one set of inabilities (i.e. cognitive inabilities). However, it is not clear whether modern perspectives have discussed whether stupidity exists in various forms-in the same way as they have envisaged intelligence. To address this limitation, 257 university members were asked to share what they perceived as being stupid educational and technological practices in their institutions. Analysis of the data suggested three concepts were important to the members: moral, spatial and administrative stupidities. That is, stupidity is perceived to come in the form of failing to meet certain moral, spatial and administrative values. This implies that modern perspectives may conceptualise stupidity differently from traditional perspectives, seeing it as going beyond cognitive inabilities and viewing it as existing in various forms (e.g. moral, spatial and administrative stupidities). Thus, there are multiple stupidities as there are multiple forms of intelligence. A strength of this research is that it views stupidity through an organisational and qualitative lens, although some may traditionally expect such a topic to be examined quantitatively through psychometric and biological approaches.

  8. Optical gravitational wave detectors on the ground and in space: theory and technology

    2010-01-01

    Major predictions of General Relativity, unforeseen at the beginning of the preceding century, are now under investigation. The existence of black holes of any mass from tens to billions of solar masses is now established, and the physics around these objects begins to be studied through direct observations in a wide electromagnetic spectrum from visible light to X-rays. General relativity, however, provides an extra medium which carries more information on the regions of intense gravitational field, namely gravitational waves (GWs). Due to their extremely weak coupling to matter, GWs are precisely generated in those regions of spacetime undergoing strong curvature, which is very exciting for modern astrophysics. On the other hand, this weak coupling makes it difficult for GWs to cause appreciable effects in human made instruments. This is why technology of GW detectors took such a long time to reach a sensitivity level consistent with GW amplitudes predicted by theoretical models of sources. In the present status, apart from resonant solid detectors, two large interferometric antennas (LIGO in the USA and the French-Italian Virgo) are beginning to produce data, and a joint ESA-NASA space mission, resulting from a wide effort of European and American groups, is reaching a crucial approval phase. The aim of the present review is to give the theoretical bases of GW detectors using light.

  12. Situated technology in reproductive health care: Do we need a new theory of the subject to promote person-centred care?

    Stankovic, Biljana

    2017-01-01

    Going through reproductive experiences (especially pregnancy and childbirth) in contemporary Western societies almost inevitably involves interaction with medical practitioners and various medical technologies in institutional context. This has important consequences for women as embodied subjects. A critical appraisal of these consequences-coming dominantly from feminist scholarship-relied on a problematic theory of both technology and the subject, which are in contemporary approaches no longer considered as given, coherent and well individualized wholes, but as complex constellations that are locally situated and that can only be described empirically. In this study, we will be relying on the developments in phenomenological theory to reconceptualize women as technologically mediated embodied subjects and on the new paradigms in philosophy of technology and STS to reconstruct medical technology as situated-with the aim of reconceptualizing their relationship and exploring different possibilities for the mediating role of medical technology. It will be argued that technologization of female reproductive processes and alienating consequences for women are not necessary or directly interrelated. The role of technology varies from case to case and depends mainly on the nontechnological and relational aspects of institutional context, in which medical practitioners play a decisive role. © 2016 John Wiley & Sons Ltd.

    This paper puts forward using high-pressure water jet technology to control rock burst in roadway, and analyzes the theory of controlling rock burst in roadway by the weak structure zone model. The weak structure zone is formed by using high-pressure water jet to cut the coal wall in a continuous and rota-tional way. In order to study the influence law of weak structure zone in surrounding rock, this paper numerically analyzed the influence law of weak structure zone, and the disturbance law of coal wall and floor under dynamic and static combined load. The results show that when the distance between high-pressure water jet drillings is 3 m and the diameter of drilling is 300 mm, continuous stress super-position zone can be formed. The weak structure zone can transfer and reduce the concentrated static load in surrounding rock, and then form distressed zone. The longer the high-pressure water jet drilling is, the larger the distressed zone is. The stress change and displacement change of non-distressed zone in coal wall and floor are significantly greater than that of distressed zone under dynamic and static com-bined load. And it shows that the distressed zone can effectively control rock burst in roadway under dynamic and static combined load. High-pressure water jet technology was applied in the haulage gate of 250203 working face in Yanbei Coal Mine, and had gained good effect. The study conclusions provide theoretical foundation and a new guidance for controlling rock burst in roadway.

    The purpose of this study was to identify how people 6-12 months after stroke were using and integrating information and communication technology (ICT) in their everyday lives. To capture the participants' experiences, one focus group and 14 individual interviews were carried out in Sweden and Denmark regarding the use of ICT in everyday life. The participants comprised 11 men and seven women aged 41-79 years. A grounded theory approach was used throughout the study and a constant comparative method was used in the analysis. Five categories were identified from the analysis of the interviews with the participants: 1) Using the mobile phone to feel safe, 2) Staying connected with others, 3) Recreating everyday life, 4) A tool for managing everyday life, and 5) Overcoming obstacles for using ICT. From these categories one core category emerged: The drive to integrate ICT in everyday life after stroke. People with stroke had a strong drive to integrate ICT in order to manage and bring meaning to their everyday lives, although sometimes they needed support and adaptations. It is not only possible but also necessary to start using ICT in rehabilitation in order to support people's recovery and promote participation in everyday life after stroke. Implications for rehabilitation People with stroke have a strong drive for using information and communication technology in their everyday lives, although support and adaptations are needed. The recovery process of people with stroke could benefit from the use of ICT in the rehabilitation and ICT could possibly contribute to independence and promote participation in everyday life. Knowledge from this study can be used in the development of an ICT-based stroke rehabilitation model.

    Barriers to report incident events using an online information system (IS) may be different from those of a paper-based reporting system. The nationwide online Patient-Safety Reporting System (PSRS) contains a value judgment behind use of the system, similar to the Value of Perceived Consequence (VPC), which is seldom discussed in ISs applications of other disciplines. This study developed a more adequate research framework by integrating the VPC construct into the well-known Unified Theory of Acceptance and Use of Technology (UTAUT) model as a theoretical base to explore the predictors of medical staff's intention to use online PSRS. The results showed that management support was an important factor to influence medical staff's intention of using PSRS. The effects of factors such as performance expectancy, perceived positive, and perceived negative consequence on medical staff's intention of using PSRS were moderated by gender, age, experience, and occupation. The results proved that the modified UTAUT model is significant and useful in predicting medical staff's intention of using the nationwide online PSRS.

    Using strong structuration theory, we aimed to understand the adoption and implementation of an electronic clinical audit and feedback tool to support medicine optimisation for patients in primary care. This is a qualitative study informed by strong structuration theory. The analysis was thematic, using a template approach. An a priori set of thematic codes, based on strong structuration theory, was developed from the literature and applied to the transcripts. The coding template was then modified through successive readings of the data. Clinical commissioning group in the south of England. Four focus groups and five semi-structured interviews were conducted with 18 participants purposively sampled from a range of stakeholder groups (general practitioners, pharmacists, patients and commissioners). Using the system could lead to improved medication safety, but use was determined by broad institutional contexts; by the perceptions, dispositions and skills of users; and by the structures embedded within the technology. These included perceptions of the system as new and requiring technical competence and skill; the adoption of the system for information gathering; and interactions and relationships that involved individual, shared or collective use. The dynamics between these external, internal and technological structures affected the adoption and implementation of the system. Successful implementation of information technology interventions for medicine optimisation will depend on a combination of the infrastructure within primary care, social structures embedded in the technology and the conventions, norms and dispositions of those utilising it. Future interventions, using electronic audit and feedback tools to improve medication safety, should consider the complexity of the social and organisational contexts and how internal and external structures can affect the use of the technology in order to support effective implementation. © Article author(s) (or their

    The objective of this study is to determine if shared decisions for managing non-critical chronic illness, made through an online biomedical technology intervention, us feasible and usable. The technology intervention incorporates behavioural and decision theories to increase patient engagement, and ultimately long term adherence to health behaviour change. We devised the iheart web intervention as a "proof of concept" in five phases. The implementation incorporates the Vaadin web application framework, Drools, EclipseLink and a MySQL database. Two-thirds of the study participants favoured the technology intervention, based on Likert-scale questions from a post-study questionnaire. Qualitative analysis of think aloud feedback, video screen captures and open-ended questions from the post-study questionnaire uncovered six main areas or themes for improvement. We conclude that online shared decisions for managing a non-critical chronic illness are feasible and usable through the iheart web intervention.

    This paper reports the use of a research-based, web-delivered, technology-and-science education context (the Generative Virtual Classroom) in which student-teachers can develop their ability to recognize, describe, analyse and theorize learning. Addressing well-recognized concerns about narrowly conceived, anachronistic and ineffective technology-and-science education, this e-learning environment aims to use advanced technologies for learning, to bring about larger scale improvement in classroom practice than has so far been effected by direct intervention through teacher education. Student-teachers' short, intensive engagement with the Generative Virtual Classroom during their practice teaching is examined. Findings affirm the worth of this research-based e-learning system for teacher education and the power of a biologically based, generative theory to make sense of the learning that occurred.

    Resource of traditional Chinese medicine residue is an inevitable choice to form new industries characterized of modem, environmental protection and intensive in the Chinese medicine industry. Based on the analysis of source and the main chemical composition of the herb residue, and for the advantages of membrane science and technology used in the pharmaceutical industry, especially membrane separation technology used in improvement technical reserves of traditional extraction and separation process in the pharmaceutical industry, it is proposed that membrane science and technology is one of the most important choices in technological design of traditional Chinese medicine resource industrialization. Traditional Chinese medicine residue is a very complex material system in composition and character, and scientific and effective "separation" process is the key areas of technology to re-use it. Integrated process can improve the productivity of the target product, enhance the purity of the product in the separation process, and solve many tasks which conventional separation is difficult to achieve. As integrated separation technology has the advantages of simplified process and reduced consumption, which are in line with the trend of the modern pharmaceutical industry, the membrane separation technology can provide a broad platform for integrated process, and membrane separation technology with its integrated technology have broad application prospects in achieving resource and industrialization process of traditional Chinese medicine residue. We discuss the principles, methods and applications practice of effective component resources in herb residue using membrane separation and integrated technology, describe the extraction, separation, concentration and purification application of membrane technology in traditional Chinese medicine residue, and systematically discourse suitability and feasibility of membrane technology in the process of traditional Chinese

    2010-08-01

    We describe a theory-driven memory intervention programme for training individuals with moderate to severe memory impairment in the use of emerging commercial technology. Here we demonstrate the application of the programme to training MK, an 18-year-old woman with severe memory impairment following treatment for a suprasellar germinoma, to autonomously use a smartphone to support her day-to-day memory. A within-subject A(1)B(1)A(2)B(2) single-case experimental design was used to evaluate the impact of smartphone use on MK's real-life functioning. Following intervention MK showed increased confidence in dealing with memory-demanding situations and generalised smartphone use across all aspects of her life as quantified by several and varied ecologically valid measures including a phone call schedule, behaviour memory observations and questionnaires. Moreover the intervention also benefited her family as indicated by a sustained reduction in caregiver strain and an increase in reported quality of life. These findings suggest that individuals with severe memory impairment, particularly young adults with potentially life-long dependence on their families, are able to capitalise on emerging commercial technology to function more autonomously. The findings also suggest that the gap between individuals with severe memory impairment and potent emerging technology can be closed by provision of a theory-driven structured training programme.

    Full Text Available How is the link between learner and technology made in mobile learning? Whatis the value of the concept of ‘affordances'? And how does research articulatingthis concept act to position mobile devices as ‘technologies for learning'? Thisliterature review used both unstructured and structured search samples of publishedresearch on mobile learning to critically evaluate the prevalence and influenceof the concept of the affordances of mobile technologies. Actor-networktheory is drawn on as a theoretical lens through which to critically considerhow this concept is articulated, and in particular to explore the way it positionsand controls mobile devices as technologies for learning. Parallels in contemporaryaccounts of mobile learning are drawn with classifications of previous discoursesaround the introduction of computers into schools. An alternativeagenda for mobile learning research is suggested with a focus on authentic andinformal contexts rather than controlled experiments.

    近代技术体系不仅要求人们认识、遵循它的自然属性,更要求人们认识、遵循它的社会属性.福泽谕吉在继承日本幕府末期佐久间象山"东洋道德、西洋艺术"思想的基础上提出的"脱亚入欧"的技术观呈现了技术的如下的社会属性:技术本质的理性主义和实证主义倾向;技术伦理的功利主义和怀疑主义倾向;技术与社会关系上的技术多维主义倾向.日本在引进西方技术时,不仅吸收近代技术的自然属性,也接纳近代技术的社会属性,故能在制度上、体制上吸收近代技术的精华,这成为日本实现近代化的重要原因.%Modern technology requires people to understand and follow not only its natural attributes, but also its social attributes. Based on Sakuma Zozan's idea "Combination of Oriental Morality with Western Art", during the end of Japanese Shogunate Period, Fukuzawa Yukich proposed the policy of "Departing from Asia for Europe" which was also a technological viewpoint implying the following social attributes of technology: the tendency to rationalism and positivism in essence, the tendency to utilitarianism and skepticism in ethics and the tendency to the multidimensional relationship between technology and society. In such a way, Japanese introduced the technologies into their motherland via absorbing not only the natural but also the social attributes of modern technologies. It followed that Japan absorbed the essence of modern technologies from the West systematically and institutionally, and such a process was just the basic reason why Japan became a modernized and developed country.

    With the widespread use of information communication technologies, computerized clinical practice guidelines are developed and considered as effective decision supporting tools in assisting the processes of clinical activities. However, the development of computerized clinical practice guidelines in Taiwan is still at the early stage and acceptance level among major users (physicians) of computerized clinical practice guidelines is not satisfactory. This study aims to investigate critical factors influencing physicians' intention to computerized clinical practice guideline use through an integrative model of activity theory and the technology acceptance model. The survey methodology was employed to collect data from physicians of the investigated hospitals that have implemented computerized clinical practice guidelines. A total of 505 questionnaires were sent out, with 238 completed copies returned, indicating a valid response rate of 47.1 %. The collected data was then analyzed by structural equation modeling technique. The results showed that attitudes toward using computerized clinical practice guidelines (γ = 0.451, p critical factors influencing physicians' intention to use computerized clinical practice guidelines, and these factors can explain 68.6 % of the variance in intention to use computerized clinical practice guidelines. This study confirmed that some subject (human) factors, environment (organization) factors, tool (technology) factors mentioned in the activity theory should be carefully considered when introducing computerized clinical practice guidelines. Managers should pay much attention on those identified factors and provide adequate resources and incentives to help the promotion and use of computerized clinical practice guidelines. Through the appropriate use of computerized clinical practice guidelines, the clinical benefits, particularly in improving quality of care and facilitating the clinical processes, will be realized.

    User acceptance is a precondition for successful implementation of hospital information systems (HISs). Increasing investment in information technology by healthcare organisations internationally has made user acceptance an important issue in technology implementation and management. Despite the increased focus on hospital information systems, there continues to be user resistance. The present study aimed to investigate the factors affecting hospital information systems nurse-user acceptance of HISs, based on the Unified Theory of Acceptance and Use of Technology (UTAUT), in the Shiraz University of Medical Sciences teaching hospitals. A descriptive-analytical research design was employed to study nurses' adoption and use of HISs. Data collection was undertaken using a cross-sectional survey of nurses (n=303). The research model was examined using the LISREL path confirmatory modeling. The results demonstrated that the nurses' behavioural intention (BI) to use hospital information systems was predicted by Performance Expectancy (PE) (β= 2.34, pinformation systems (R2 = 0.728). Application of the research model suggested that nurses' acceptance of HISs was influenced by performance expectancy, effort expectancy, social influence and facilitating conditions, with performance expectancy having the strongest effect on user intention.

    Background: The relationship between technology-assisted supplemental work and well-being outcomes is a recent issue in scientific literature. Whether the use of technology for work purpose in off-work time may have a positive or negative impact on work-family balance remains an open question and the role of gender in this relationship is poorly understood. Aim: According to the JD-R theory, this study aimed to investigate the relationship between off-work hours technology assisted job demand (off-TAJD) and both work-family conflict (WFC) and work-family enrichment (WFE). Moreover, it considered two general job demands, workload and emotional dissonance, and one job resource, supervisory coaching. Method: The hypotheses were tested with a convenience sample of 671 workers. Data were collected with a self-report questionnaire and analyzed with SPSS 23 and through multi-group structural equation model (SEM) (Mplus 7). Results: The estimated SEM [Chi-square (510) = 1041.29; p < 0.01; CFI = 0.95; TLI = 0.95; RMSEA = 0.06 (0.05, 0.06); SRMR = 0.05. M = 319/F = 352] showed that off-TAJD was positively related to WFC in both subsamples; off-TAJD was positively related also to WFE only in the Male group. Workload was positively related to WFC in both Male and Female subsamples. Emotional dissonance was positively related to WFC in both subsamples and was negatively related to WFE. Supervisory coaching was strongly, positively related to WFE in both groups, and only in the Male subsample presented a low negative relationship with WFC. Conclusion: This study contributes to the literature on new challenges in work-life interface by analyzing the association between off-TAJD and WFC and Enrichment. Our findings suggest it is important to pay attention to gender differences in the study of the impact of supplemental work carried out during off-work hours using technology on the work-life interface.

It was found that for use in food technology is preferable to use a method is-cold-pressed wheat germ, under which the processed products do not present a residual amount of solvents and other non-food components. Given food and biological characteristics of wheat germ and products deep processing, it was found that they contain vitamin E, A, D, vitamin group В, more than 20 macro- and microelements. Methods of extracting oil from different types raw materials. Analyzed the functional role of ω-6 and ω -3 fatty acids for the human body and ways to maintain balance. A review of plant oils, the prospects of its use to create food systems balanced composition of fatty acids. It was found that the ratio of ω-6 and ω -3 fatty acids in wheat germ oil does not meet the recommended therefore to establish the necessary balance it is preferable to mix amaranth oil and pumpkin. Classified the factors affecting the quality parameters of wheat germ stored, evaluated the role of the enzyme complex during storage of wheat germ and their products deep processing. It was found that a significant effect on the damage of wheat germ has a dual action of lipase, lipoxygenase and catalase. Given the storage and stabilization of wheat germ, shows the potential use of stabilizers to increase the shelf life of wheat germ. As stabilizers, preference is given to compositions of organic acids: ascorbic, succinic and fumaric. It is proved that the composition of organic acids suppress the activity of lipase and lipoxygenase catalase by wheatgerm type noncompetitive inhibition. A review of the technologies used wheat germ and products of their complex processing in medical, cosmetic, feed and food industry.

    2016-02-01

    A virtual pet in the form of a mid-sized dog was developed based on the framework of social cognitive theory and tested as a vehicle for promoting fruit and vegetable (F&V) consumption in children. Three groups of children (N = 68) between the ages of 7 and 13 years were studied: baseline (no treatment), computer only, and virtual dog. Children in the virtual dog condition interacted with the virtual dog for 3 days, setting F&V consumption goals and receiving evaluation and reinforcement based on whether they met their self-set goals. Children vicariously experienced future health outcomes of F&V consumption by seeing, hearing, and feeling their virtual dog's physical and mental health improve or deteriorate based on their F&V consumption in the physical world. Children in the computer only condition interacted with a computer system that presented equivalent features, but without the virtual dog. Children in the baseline condition did not receive any experimental treatment. Results indicated that children in the virtual dog condition chose to be served significantly more F&V than those in the computer only or baseline conditions did. However, children in the virtual dog condition were unable to consume significantly more F&V than those in the computer only condition, although children in those two conditions consumed more F&V than the baseline condition. Food preferences did not differ significantly across the three conditions before and after the experimental treatments. Theoretical and practical potentials of using a virtual pet to promote F&V consumption systematically in children are discussed.

    There has been much criticism of the NHS national programme for information technology (IT); it has been an expensive programme and some elements appear to have achieved little. The Hayes report was written as an independent review of health and social care IT in England. To identify key principles for health IT implementation which may have relevance beyond the critique of NHS IT. We elicit ten principles from the Hayes report, which if followed may result in more effective IT implementation in health care. They divide into patient-centred, subsidiarity and strategic principles. The patient-centred principles are: 1) the patient must be at the centre of all information systems; 2) the provision of patient-level operational data should form the foundation - avoid the dataset mentality; 3) store health data as close to the patient as possible; 4) enable the patient to take a more active role with their health data within a trusted doctor-patient relationship. The subsidiarity principles set out to balance the local and health-system-wide needs: 5) standardise centrally - patients must be able to benefit from interoperability; 6) provide a standard procurement package and an approved process that ensures safety standards and provision of interoperable systems; 7) authorise a range of local suppliers so that health providers can select the system best meeting local needs; 8) allow local migration from legacy systems, as and when improved functionality for patients is available. And finally the strategic principles: 9) evaluate health IT systems in terms of measureable benefits to patients; 10) strategic planning of systems should reflect strategic goals for the health of patients/the population. Had the Hayes principles been embedded within our approach to health IT, and in particular to medical record implementation, we might have avoided many of the costly mistakes with the UK national programme. However, these principles need application within the modern IT

    Schraube, Ernst

    Contemporary conceptualizations of technology go beyond the traditional interpretation of created things as simply neutral means to an end. They theorize technologies as objects, which embody regimes of power (the theory of technological politics), or scripts (actor-network theory), or values...... (critical theory of technology), or patriarchal thought structures (feminist theories of technology). As helpful as these theories may be to understand the inner relationship between the technosphere and human life, the way in which the life of the individuals in the world of things is imagined remains...... vague and imprecise. In this paper I will argue for a social theory of technology, which includes the subjective and intersubjective implications of technological artifacts. I will show how acting has shifted from the province of human subjects to the sphere of work and products. The created things now...

    Full Text Available An intelligent tour service system including an augmented reality (AR tour-sharing Application (APP and a query-answering server was developed in this study to promote tourist attractions involving local Hakka culture in Thailand. Subsequently, use of this APP to navigate Hakka culture tourist attractions in Thailand was observed. The novel random neural networks (RNNs were proposed to obtain query-answering services, and the practical experimental results showed that the accuracy of RNNs was 99.51%. This study also integrated the Technology Acceptance Model with Uses and Gratifications Theory to predict the gratification, usage intention, and user attitudes toward marketed attractions of the AR tour-sharing APP. A questionnaire survey was conducted, and 446 valid questionnaires were returned. The following results were obtained: (a self-presentation and perceived usefulness (PU directly influenced gratification; (b perceived entertainment indirectly influenced gratification through perceived ease of use and PU, and information sharing indirectly influenced gratification through PU; and (c gratification was significantly and positively related to usage intention and attitude toward attractions. Based on these results, suggestions that new technology marketing can be used to promote causes other than Hakka tourist attractions established in Thailand can be contrived. For example, the tour-sharing APP developed in this study could be applied to emphasize the characteristics of Thai Hakka culture; users’ fondness for self-presentation and information sharing can be used for word-of-mouth marketing to attract additional visitors. In addition, this research provides a reference for enterprises and marketers regarding the use of AR tour-sharing APPs to market tourist attractions, and also for future related studies.

There is little research on how older Culturally And Linguistically Diverse (CALD) migrants who have 'aged in place' find health information, and the role which digital technology plays in this. Although the research for this paper was not focused on cancer, we draw out implications for providing cancer-related information to this group. We interviewed 54 participants (14 men and 40 women) aged 63-94 years, who were born in Italy or Greece, and who migrated to Australia mostly as young adults after World War II. Constructivist grounded theory and social network analysis were used for data analysis. Participants identified doctors, adult children, local television, spouse, local newspaper and radio as the most important information sources. They did not generally use computers, the Internet or mobile phones to access information. Literacy in their birth language, and the degree of proficiency in understanding and using English, influenced the range of information sources accessed and the means used. The ways in which older CALD migrants seek and access information has important implications for how professionals and policymakers deliver relevant information to them about cancer prevention, screening, support and treatment, particularly as information and resources are moved online as part of e-health.

    Full Text Available This study aims to assess the factors which influence taxpayer behavior in utilizing e-filling tax system. This study combines Technology Acceptance Model and the Theory of Planned Behavior. The data was collected through a survey method. It took 100 respondents of the personal taxpayers of the Pratama Gresik Utara tax office's employee in utilizing the e-filing to submit their tax return. In order to assess the data, the researchers used Partial Least Square statistical method. The finding shows that the intention construct has a positive influence over the e-filling utilization behavior. Behavioral control has a positive influence over the behavior through the e-filing utilization intention. Easy of use, purpose, attitude, subjective norm, and behavioral control have a positive influence over the e-filing utilization intention. Credibility has a negative influence over the e-filing utilization intention. This study involved the Application Service Provider, Directorate General of Taxes, and KPP Pratama which have to more pay attention the behavior, intention, easy of use, purpose, attitude, subjective norm, and behavioral control of the taxpayer.

  13. Determinants of IT-Related Innovation Acceptance and Use Behavior: Theoretical Integration of Unified Theory of Acceptance and Use of Technology and Entrepreneurial Potential Model

    Full Text Available Purpose – a great number of models investigate individual intention towards adopting and using information technology. However, the complex link between intention and behavior suggests that it may require more scrutiny (intention behavior gap. The link between the intention and behavior is most likely influenced by a number of factors, some controllable, others uncontrollable; therefore, external factors are likely to play a significant role. However, IS literature on the subject is extremely lacking. One of the popular theories in this context is the UTAUT model, which has certain limitations, especially when it concerns intention behavior gaps. Research on the entrepreneurship context identified precipitating events as a promising candidate to overcome such limitations. To address the gap in the UTAUT and improve the model, it is reviewed and empirically compared to the Entrepreneurial Potential Model (EPM in order to allow us to develop a new model that integrates elements from the two models in order to capture the different factors of IT adoption behavior.Methodology – a longitudinal survey approach is appropriate for this study, since this research design allows the researcher to test the overall fit of the integrative TADU model. The longitudinal study is appropriate to test the relationship between intention and use behavior and the effect of precipitating events on the time that intention is formed and behavior is performed. This is an ongoing research, and at this stage, the authors are mainly developing a theoretical argument and methodology that is currently in the process of being tested.Results – the new model mitigates the limitations arising from the UTAUT, particularly its predictive ability, and it also reduces the ‘distal nature’ between intention and use behavior.Study limitation – the paper represents work in progress and may some researcher criticize it in term of the predicted results.Practical significance

    1984-01-01

    Our intent in producing this book was to provide a text that would be comprehensive enough for an introductory course in integrated optics, yet concise enough in its mathematical derivations to be easily readable by a practicing engineer who desires an overview of the field. The response to the first edition has indeed been gratifying; unusually strong demand has caused it to be sold out during the initial year of publication, thus providing us with an early opportunity to produce this updated and improved second edition. This development is fortunate, because integrated optics is a very rapidly progressing field, with significant new research being regularly reported. Hence, a new chapter (Chap. 17) has been added to review recent progress and to provide numerous additional references to the relevant technical literature. Also, thirty-five new problems for practice have been included to supplement those at the ends of chapters in the first edition. Chapters I through 16 are essentially unchanged, except for ...

    2017-01-01

    This contributed volume is the result of a July 2010 workshop at the University of Wuppertal Interdisciplinary Centre for Science and Technology Studies which brought together world-wide experts from physics, philosophy and history, in order to address a set of questions first posed in the 1950s: How do we compare spacetime theories? How do we judge, objectively, which is the “best” theory? Is there even a unique answer to this question? The goal of the workshop, and of this book, is to contribute to the development of a meta-theory of spacetime theories. Such a meta-theory would reveal insights about specific spacetime theories by distilling their essential similarities and differences, deliver a framework for a class of theories that could be helpful as a blueprint to build other meta-theories, and provide a higher level viewpoint for judging which theory most accurately describes nature. But rather than drawing a map in broad strokes, the focus is on particularly rich regions in the “space of spaceti...

    2015-01-01

    Full Text Available The objective of this article is to analyze the relationship between theoretical and practical knowledge in accounting training based on the political-pedagogical foundations of higher education in the state of Paraiba. For that, we turn to the contributions of Jürgen Habermas’s theory of communicative action in order to understand how the relationship is established between theoretical discourse and practical discourse, drawing on definitions of "instrumental reason" and "communicative reason". To develop this empirical classification study, with a quantitative and qualitative approach, we employed the exploratory typology through bibliographic and documentary research. For data collection we applied a questionnaire with closed questions to students/interns of the public institutions analyzed. The results of the questionnaire show that the courses have an eminently theoretical format. Full-time practices are not applied and their focus is on the "modus operandi". We note that in accounting training, practice cannot be dissociated from theory and vice versa.

    Claudia Patricia Arredondo-González

    2009-03-01

    Full Text Available El propósito de este artículo es mostrar cómo la deshumanización de los cuidados de enfermería no se debe sólo a la tecnología, sino que es multifactorial, además, resaltar las relaciones interpersonales en la práctica humanizada. Para esto, a manera de orientación metodológica, se aborda la teoría de las relaciones interpersonales de Hildegard E. Peplau como paso previo a la enumeración de los factores deshumanizantes que confluyen en el medio hospitalario y han sido identificados en la bibliografía. Asimismo, se desarrolla una reflexión sobre la función de la tecnología como un medio para la humanización de los cuidados. Finalmente, se muestra la teoría de las relaciones interpersonales como base teórica para la humanización de la atención de enfermería, tanto en la formación como en práctica profesional. Esta teoría, claramente entiende el recurso tecnológico como medio y posiciona al paciente como fin único del cuidado de enfermería.The purpose of this paper is to show that technology is not the only cause of dehumanization of nursing care but it is a multifactor phenomenon and to highlight human relations as the cornerstone of a humane practice. Hildergard E. Peplau theory of human relations is used as methodological framework and as a previous step to identify dehumanizing factors that operate in the hospital realm and have been identified in the literature. In addition, de paper develops a refection about the role that technology as a means in humanizing nursing care. Finally, the papers shows the theory of the interpersonal relations as theoretical support the humanization of nursing care in both its education and in its practice. This theory clearly understands technology as a means and the patient as the sole end of nursing care.

    2008-06-01

    This study explores attitudinal and behavioral patterns when using Cyworld by adopting an expanded Technology Acceptance Model (TAM). A model for Cyworld acceptance is used to examine how various factors modified from the TAM influence acceptance and its antecedents. This model is examined through an empirical study involving Cyworld users using structural equation modeling techniques. The model shows reasonably good measurement properties and the constructs are validated. The results not only confirm the model but also reveal general factors applicable to Web2.0. A set of constructs in the model can be the Web2.0-specific factors, playing as enhancing factor to attitudes and intention.

  12. Translating Scientific Judgment, Technological Insight and Economic Theory Into Practical Policy Lessons: The Case of Climate Regulation in the United States

    Mignone, B. K.

    2008-12-01

    Effective solutions to the climate change problem will require unprecedented cooperation across space, continuity across time and coordination between disciplines. One well-known methodology for synthesizing the lessons of physical science, energy engineering and economics is integrated assessment. Typically, integrated assessment models use scientific and technological relationships as physical constraints in a larger macroeconomic optimization that is designed to either balance the costs and benefits of climate change mitigation or find the least-cost path to an exogenously prescribed endpoint (e.g. atmospheric CO2 stabilization). The usefulness of these models depends to a large extent on the quality of the assumptions and the relevance of the outcome metrics chosen by the user. In this study, I show how a scientifically-based emissions reduction scenario can be combined with engineering-based assumptions about the energy system (e.g. estimates of the marginal cost premium of carbon-free technology) to yield insights about the price path of CO2 under a future regulatory regime. I then show how this outcome metric (carbon price) relates to key decisions about the design of a future cap-and-trade system and the way in which future carbon markets may be regulated.

    基于对技术轨道理论的评述,从服务自身的特性出发,对服务创新轨道的概念进行归纳分析,阐释服务创新轨道的内涵、特性,比较服务创新轨道与技术创新轨道的异同。结果显示:第一,解决因服务特性而产生的问题,是形成服务创新轨道的根本基础,这内在规定了服务创新活动的方向和路径;第二,市场、科技和制度环境等外部规定性要素,以及企业的战略和知识基础等,也对服务创新轨道的形成产生重要影响;第三,服务创新轨道的概念更为宽泛,与具有严格内在技术规定性的制造业技术轨道相比,服务创新轨道具有多样性、非排斥性、弱连续性等特性;第四,技术轨道理论只在一定程度上适用于服务创新,技术轨道是服务创新的一种可选轨道。%This paper studies the concept of service innovation trajectory based on the discussion of technological trajectory theory and the anal ysis on the features of service activities. Four main findings are listed. The first is that,innovation trajectory in services is a type of problem-sol; ving trajectory whieh originated from the traits of services activities. The second is that,in addition to service traits, external faetors such as market,institution and science ~ technology,and firm factors such as strategy and knowledge base, would also influence innovation trajectory in services. The third is that, relative to technological trajectory, service innovation trajectory shows some specific characteristics such as weak ac~ cumulation,non-exclusion of other trajectories and diversity. The last is that,technological trajectory is applicable to service innovation activities to a certain degree. It tries to contribute to the catching-up process of services in latecomers and also contribute to the development of innovation trajectory theory.

    Manning, Robert M.

    1991-01-01

    The dynamic and composite nature of propagation impairments that are incurred on Earth-space communications links at frequencies in and above 30/20 GHz Ka band, i.e., rain attenuation, cloud and/or clear air scintillation, etc., combined with the need to counter such degradations after the small link margins have been exceeded, necessitate the use of dynamic statistical identification and prediction processing of the fading signal in order to optimally estimate and predict the levels of each of the deleterious attenuation components. Such requirements are being met in NASA's Advanced Communications Technology Satellite (ACTS) Project by the implementation of optimal processing schemes derived through the use of the Rain Attenuation Prediction Model and nonlinear Markov filtering theory.

    Cognitive radio technology, which can improve the utilization rate of spectrum resources, has broad application prospect , and is likely to lead to another major revolution in the field of wireless communications. Spectrum sensing is the first step of cognitive radio technology, but its performance is far from the actual needs. Developed a truly practical application of high-performance spectrum sensing method has become an urgent problem to be solved. In recent years, a new theory closely related to wireless communications , random matrix theory ( RMT) , has been further applied to achieve a high performance in the field of spectrum sensing. New algorithms based on RMT and the latest research rusults, non-asymptotic random matrix theory (Non-Asymptotic RMT) , are expected to be the true high-performance sensing technology to practical applications. Therefore, the research on spectrum sensing technology based on random matrix theory has very important theoretical and practical value. This paper summarizes the development process of RMT in areas of cognitive radio spectrum sensing; introduces its basic principle, summed up its main characteristics, and prospects for further research.%认知无线电技术,可以提高频谱资源的利用率,应用前景广阔,极有可能引发无线通信领域的又一次重大变革.但频谱感知作为认知无线电技术的首要环节,其性能还远不能满足实际需要.研究出一种真正能够实际应用的高性能频谱感知方法已经成为一个亟待解决的问题.近年来,与无线通信领域密切相关的新理论——随机矩阵理论(RMT),在频谱感知领域得到了进一步的应用,实现了高性能频谱感知.且RMT最新研究成果——非渐近随机矩阵理论(Non-Asymptotic RMT)有望将这项高性能感知技术真正推向实际应用.因此,基于随机矩阵理论的频谱感知技术具有重要的研究价值.本文总结RMT在认知无线电频谱感知领域的发展历程

    2012-10-01

    The Master in Space Science and Technology is a postgraduate course at the Universidad del País Vasco in Spain (http://www.ehu.es/aula-espazio/master.html). It has two elective itineraries on space studies: scientific and technological. The scientific branch is intended for students aiming to access the PhD doctorate program in different areas of space science, among them the research of the solar system bodies. The theoretical foundations for the solar system studies are basically treated in four related matters: Astronomy and Astrophysics, Physics of the Solar System, Planetary Atmospheres, and Image Processing and Data Analysis. The practical part is developed on the one hand by analyzing planetary images obtained by different spacecrafts from public archives (e. g. PDS), and on the other hand from observations obtained by the students employing the 50 cm aperture telescope and other smaller telescopes from the Aula EspaZio Gela Observatory at the Engineering Faculty. We present the scheme of the practice works realized at the telescope to get images of the planets in different wavelengths pursuing to study the following aspects of Planetary Atmospheres: (1) Data acquisition; (2) Measurements of cloud motions to derive winds; (3) Measurement of the upper cloud reflectivity at the different wavelengths and position in the disk to retrieve the upper cloud properties and vertical structure. The theoretical foundations accompanying these practices are then introduced: atmospheric dynamics and thermodynamics, and the radiative transfer problem.

  15. Set theory and physics

    Energy Technology Data Exchange (ETDEWEB)

    Svozil, K. [Univ. of Technology, Vienna (Austria)

    1995-11-01

    Inasmuch as physical theories are formalizable, set theory provides a framework for theoretical physics. Four speculations about the relevance of set theoretical modeling for physics are presented: the role of transcendental set theory (i) in chaos theory, (ii) for paradoxical decompositions of solid three-dimensional objects, (iii) in the theory of effective computability (Church-Turing thesis) related to the possible {open_quotes}solution of supertasks,{close_quotes} and (iv) for weak solutions. Several approaches to set theory and their advantages and disadvantages for physical applications are discussed: Cantorian {open_quotes}naive{close_quotes} (i.e., nonaxiomatic) set theory, contructivism, and operationalism. In the author`s opinion, an attitude, of {open_quotes}suspended attention{close_quotes} (a term borrowed from psychoanalysis) seems most promising for progress. Physical and set theoretical entities must be operationalized wherever possible. At the same time, physicists should be open to {open_quotes}bizarre{close_quotes} or {open_quotes}mindboggling{close_quotes} new formalisms, which need not be operationalizable or testable at the time of their creation, but which may successfully lead to novel fields of phenomenology and technology.

    针对难处理白钨矿的冶炼问题,采用热球磨(机械活化)工艺,成功地实现了高钙黑钨矿乃至白钨矿的氢氧化钠分解并在国内广泛推广应用,这种工艺过去国外专家基于理论分析和工程实践认为是不可能的.针对新技术带来的理论问题,进行了详细的热力学研究,在实验测定的基础上,绘制了(CaO-) Na2O-WO3-H2O系赝三元相图.该赝三元相图不仅对机械活化碱分解白钨矿的工艺给出了合理的热力学解释,同时还说明即便在单纯的高压釜中白钨矿的碱分解过程也有良好的热力学窗口,为碱压煮分解工艺提供了理论基础,使之成为当前钨矿分解的主流工艺.此外,(CaO-) Na2O-WO3-H2O系赝三元相图从理论上还预测了更为普遍的白钨矿常压碱分解的工作窗口,即过程中保持NaOH浓度超过临界值,则甚至不必采用高温压煮的工作条件也能实现白钨矿的分解.研究中考虑到较低温度下高浓度NaOH分解矿浆具有极高黏度的特性,为解决分解过程的传质和动力学传质问题,借鉴了高分子塑料加工领域处理高黏度物料的成功经验,发明了在双螺杆挤出机中,连续分解黑、白钨精矿的“反应挤出法”碱分解工艺.%A mechanochemical technology was developed for the alkali decomposition of high-calcium wolframite, or even scheelite ores, for the effective utilization of the refractory scheelite resources. It was widely applied in the domestic tungsten industries. Yet this scheelite alkali decomposition used to be discouraged by some foreign experts based on their theoretical analysis and engineering practices. For this "contradiction" visualized by our experimental results, thermodynamic studies were performed, with the (CaO-)Na2O-WO3-H2O pseudo-ternary-system phase diagram plotted upon our previous experimental data. The diagram gave a reasonable explanation to the mechanical activation process and demonstrated a good thermodynamics

    2012-01-01

    How to promote technological innovation is a key issue for firms under dynamic environment. This paper develops a theoretical framework to analyze the relationship between organizational flexibility and technological innovation based on strategic orientation theory and empirically tested the relevant hypotheses. This paper finds that capability flexibility and resources flexibility have different effects on technological innovation. Resources flexibility has positive effect on incremental innovation while negative effect on radical innovation. However, capability flexibility has positive effect on both incremental and radical innovation. Customer orientation can only improve resource flexibility while have no significant effect on capability flexibility. Entrepreneurial orientation can improve capability flexibility while reducing resources flexibility. In conclude, through investigation of different effects of strategic orientations on organizational flexibility, this paper suggests that different kinds of strategic orientations may have different effect on technological innovation.%如何提高组织柔性推动技术创新是动态环境下企业关心的重要问题.本研究在组织柔性理论和创新理论基础上,提出了基于战略导向的分析框架,并在调研基础上对各假设关系进行了实证检验.研究发现:能力柔性和资源柔性对技术创新产生不同的影响.资源柔性对渐进创新起促进作用,但对突变创新反而有不利的影响;而能力柔性对突变创新和渐进创新均有正向的推动作用.顾客导向只能提高资源柔性,对能力柔性没有显著的影响;企业家导向会增强企业的能力柔性,但会降低企业的资源柔性.研究通过分析不同战略导向对企业柔性影响的差异,阐述了导向对技术创新的不同作用.

    BACKGROUND:Recovery of motor and sensory function from peripheral nerve injury is relatively slow and incomplete. It is a difficult problem for orthopedic surgeons that mainly leads to the decline in the quality of life in patients. OBJECTIVE: To conclude the methods and corresponding outcomes in peripheral nerve regeneration by analyzing the new treatment means for peripheral nerve injury. METHODS:PubMed, Wanfang, CNKI databases were retrieved for relevant articles using key words of “nerve injury, regeneration”, and then retrieval data were sorted and analyzed. RESULTS AND CONCLUSION:In recent years, in-depth studies on peripheral nerve repair have been made in the folowing aspects: surgical mode, drug, cytokine, gene transfer and biomaterials as wel as traditional Chinese medicine. If the detect size is four times longer than the diameter of nerves, the nerve regeneration chamber can achieve good outcomes.

    CERN Document Server

    Liu, Baoding

    2015-01-01

    When no samples are available to estimate a probability distribution, we have to invite some domain experts to evaluate the belief degree that each event will happen. Perhaps some people think that the belief degree should be modeled by subjective probability or fuzzy set theory. However, it is usually inappropriate because both of them may lead to counterintuitive results in this case. In order to rationally deal with belief degrees, uncertainty theory was founded in 2007 and subsequently studied by many researchers. Nowadays, uncertainty theory has become a branch of axiomatic mathematics for modeling belief degrees. This is an introductory textbook on uncertainty theory, uncertain programming, uncertain statistics, uncertain risk analysis, uncertain reliability analysis, uncertain set, uncertain logic, uncertain inference, uncertain process, uncertain calculus, and uncertain differential equation. This textbook also shows applications of uncertainty theory to scheduling, logistics, networks, data mining, c...

However, information science and knowledge organization cannot avoid relating to theories of concepts. Knowledge...... organizing systems (e.g. classification systems, thesauri and ontologies) should be understood as systems basically organizing concepts and their semantic relations. The same is the case with information retrieval systems. Different theories of concepts have different implications for how to construe......, evaluate and use such systems.

  2. Technology Adoption: an Interaction Perspective

    Science.gov (United States)

    Sitorus, Hotna M.; Govindaraju, Rajesri; Wiratmadja, I. I.; Sudirman, Iman

    2016-02-01

    The success of a new technology depends on how well it is accepted by its intended users. Many technologies face the problem of low adoption rate, despite the benefits. An understanding of what makes people accept or reject a new technology can help speed up the adoption rate. This paper presents a framework for technology adoption based on an interactive perspective, resulting from a literature study on technology adoption. In studying technology adoption, it is necessary to consider the interactions among elements involved in the system, for these interactions may generate new characteristics or new relationships. The interactions among elements in a system adoption have not received sufficient consideration in previous studies of technology adoption. Based on the proposed interaction perspective, technology adoption is elaborated by examining interactions among the individual (i.e. the user or prospective user), the technology, the task and the environment. The framework is formulated by adopting several theories, including Perceived Characteristics of Innovating, Diffusion of Innovation Theory, Technology Acceptance Model, Task-Technology Fit and usability theory. The proposed framework is illustrated in the context of mobile banking adoption. It is aimed to offer a better understanding of determinants of technology adoption in various contexts, including technology in manufacturing systems.

    2011-01-01

    Full Text Available The emerging structures in spinodal dewetting of thin nano films and spinodal decomposition of binary mixtures are found to be similar with certain differences attributed to the nonlinearities inherent in the wetting forces. This paper deals with the technological aspects of the spinodal processes by giving a brief account of the theory and to correlate the two phenomena termed as spinodal dewetting of thin nanofilms and surface-directed phase separation. The MC simulation micrographs at early stage of spinodal dewetting of a (linear polymer film confined between two hard walls (using FENE potential between the beads on same chain and Morse potential between inter and intra chain beads show similarities with surface-directed phase separation (using metropolis algorithm in creation of holes. The spinodal dewetting is also criticized on the basis of global minimization of free energy emerging from dipole-quadrupole interactions. A novel molecular scale-driving mechanism coming from asymmetric interface formation in spinodal processes is also proposed. It can be believed that the modeling done with the films under confinement of two walls works as a classical mathematical ansatz to the dipole-quadrupole interaction coming from quantum origins and giving rise to lateral interactions in the process reflecting a colossal behavior in thin nano films though weak in nature.

    Full Text Available The purpose of this paper is to compare probability theory with possibility theory, and to use this comparison in comparing probability theory with fuzzy set theory. The best way of comparing probabilistic and possibilistic conceptualizations of uncertainty is to examine the two theories from a broader perspective. Such a perspective is offered by evidence theory, within which probability theory and possibility theory are recognized as special branches. While the various characteristic of possibility theory within the broader framework of evidence theory are expounded in this paper, we need to introduce their probabilistic counterparts to facilitate our discussion.

    Carroll, Joseph; Clasen, Mathias; Jonsson, Emelie

    2017-01-01

    Biocultural theory is an integrative research program designed to investigate the causal interactions between biological adaptations and cultural constructions. From the biocultural perspective, cultural processes are rooted in the biological necessities of the human life cycle: specifically human...... and ideological beliefs, and artistic practices such as music, dance, painting, and storytelling. Establishing biocultural theory as a program that self-consciously encompasses the different particular forms of human evolutionary research could help scholars and scientists envision their own specialized areas...... of research as contributions to a coherent, collective research program. This article argues that a mature biocultural paradigm needs to be informed by at least 7 major research clusters: (a) gene-culture coevolution; (b) human life history theory; (c) evolutionary social psychology; (d) anthropological...

  6. Disruptive technologies in higher education

    Directory of Open Access Journals (Sweden)

    Michael Flavin

    2012-08-01

    Full Text Available This paper analyses the role of “disruptive” innovative technologies in higher education. In this country and elsewhere, Higher Education Institutions (HEIs have invested significant sums in learning technologies, with Virtual Learning Environments (VLEs being more or less universal, but these technologies have not been universally adopted and used by students and staff. Instead, other technologies not owned or controlled by HEIs are widely used to support learning and teaching. According to Christensen's theory of Disruptive Innovation, these disruptive technologies are not designed explicitly to support learning and teaching in higher education, but have educational potential. This study uses Activity Theory and Expansive Learning to analyse data regarding the impact of disruptive technologies. The data were obtained through a questionnaire survey about awareness and use of technologies, and through observation and interviews, exploring participants’ actual practice. The survey answers tended to endorse Disruptive Innovation theory, with participants establishing meanings for technologies through their use of them, rather than in keeping with a designer's intentions. Observation revealed that learners use a narrow range of technologies to support learning, but with a tendency to use resources other than those supplied by their HEIs. Interviews showed that participants use simple and convenient technologies to support their learning and teaching. This study identifies a contradiction between learning technologies made available by HEIs, and technologies used in practice. There is no evidence to suggest that a wide range of technologies is being used to support learning and teaching. Instead, a small range of technologies is being used for a wide range of tasks. Students and lecturers are not dependent on their HEIs to support learning and teaching. Instead, they self-select technologies, with use weighted towards established brands. The

  7. Ordering theories: Typologies and conceptual frameworks for sociotechnical change.

    Sovacool, Benjamin K; Hess, David J

    2017-06-01

    What theories or concepts are most useful at explaining socio technical change? How can - or cannot - these be integrated? To provide an answer, this study presents the results from 35 semi-structured research interviews with social science experts who also shared more than two hundred articles, reports and books on the topic of the acceptance, adoption, use, or diffusion of technology. This material led to the identification of 96 theories and conceptual approaches spanning 22 identified disciplines. The article begins by explaining its research terms and methods before honing in on a combination of fourteen theories deemed most relevant and useful by the material. These are: Sociotechnical Transitions, Social Practice Theory, Discourse Theory, Domestication Theory, Large Technical Systems, Social Construction of Technology, Sociotechnical Imaginaries, Actor-Network Theory, Social Justice Theory, Sociology of Expectations, Sustainable Development, Values Beliefs Norms Theory, Lifestyle Theory, and the Unified Theory of Acceptance and Use of Technology. It then positions these theories in terms of two distinct typologies. Theories can be placed into five general categories of being centered on agency, structure, meaning, relations or norms. They can also be classified based on their assumptions and goals rooted in functionalism, interpretivism, humanism or conflict. The article lays out tips for research methodology before concluding with insights about technology itself, analytical processes associated with technology, and the framing and communication of results. An interdisciplinary theoretical and conceptual inventory has much to offer students, analysts and scholars wanting to study technological change and society.

    Ian Stewart's Galois Theory has been in print for 30 years. Resoundingly popular, it still serves its purpose exceedingly well. Yet mathematics education has changed considerably since 1973, when theory took precedence over examples, and the time has come to bring this presentation in line with more modern approaches.To this end, the story now begins with polynomials over the complex numbers, and the central quest is to understand when such polynomials have solutions that can be expressed by radicals. Reorganization of the material places the concrete before the abstract, thus motivating the g

  12. Focus on Technologies: Worry or Technology?

    Directory of Open Access Journals (Sweden)

    Saulius Kanišauskas

    2015-10-01

    Full Text Available The paper analyses different attitudes towards technologies in contemporary philosophical discourses. It points out that classical notion of technology formulated by Martin Heidegger seems to be more and more often questioned and even forgotten. As a result, it is being replaced by the theory of determinism, according to which the change of technologies determines the changes in social systems, the human being including. This happens this way and not vice versa. Nowadays technē, or “technika” (in English: technology is mostly understood in the instrumental meaning or in the meaning of power. It is considered to be a powerful means, tool or mechanism to influence, change, control and manipulate human consciousness and human feelings. Despite the fact that technologies have already been tamed, the problem of huge responsibility for using and developing them arises. It is questioned whether the increasing society’s attention to modern technologies is not a particular “technology” of the postmodern capitalism to manipulate social consciousness. In parallel with “yes” answer to this question, Albert Borgmann’s idea that the causes of technological development have an ontological dimension, i.e. the causes are rooted in the nature of human beings themselves and their desire to adore own creativity, is discussed. Thus, it becomes necessary to probe deeper into the nature of creativity.

  14. Effective theories of universal theories

    CERN Document Server

    Wells, James D

    2015-01-01

    It is well-known but sometimes overlooked that constraints on the oblique parameters (most notably $S$ and $T$ parameters) are only applicable to a special class of new physics scenarios known as universal theories. In the effective field theory (EFT) framework, the oblique parameters should not be associated with Wilson coefficients in a particular operator basis, unless restrictions have been imposed on the EFT so that it describes universal theories. We work out these restrictions, and present a detailed EFT analysis of universal theories. We find that at the dimension-6 level, universal theories are completely characterized by 16 parameters. They are conveniently chosen to be: 5 oblique parameters that agree with the commonly-adopted ones, 4 anomalous triple-gauge couplings, 3 rescaling factors for the $h^3$, $hff$, $hVV$ vertices, 3 parameters for $hVV$ vertices absent in the Standard Model, and 1 four-fermion coupling of order $y_f^2$. All these parameters are defined in an unambiguous and basis-indepen...

  15. Guiding healthcare technology implementation: a new integrated technology implementation model.

    Science.gov (United States)

    Schoville, Rhonda R; Titler, Marita G

    2015-03-01

    Healthcare technology is used to improve delivery of safe patient care by providing tools for early diagnosis, ongoing monitoring, and treatment of patients. This technology includes bedside physiologic monitors, pulse oximetry devices, electrocardiogram machines, bedside telemetry, infusion pumps, ventilators, and electronic health records. Healthcare costs are a challenge for society, and hospitals are pushed to lower costs by discharging patients sooner. Healthcare technology is being used to facilitate these early discharges. There is little understanding of how healthcare facilities purchase, implement, and adopt technology. There are two areas of theories and models currently used when investigating technology: technology adoption and implementation science. Technology adoption focuses mainly on how the end users adopt technology, whereas implementation science describes methods, interventions, and variables that promote the use of evidence-based practice. These two approaches are not well informed by each other. In addition, amplifying the knowledge gap is the limited conceptualization of healthcare technology implementation frameworks. To bridge this gap, an all-encompassing model is needed. To understand the key technology implementation factors utilized by leading healthcare facilities, the prevailing technology adoption and implementation science theories and models were reviewed. From this review, an integrated technology implementation model will be set forth.

    Friedrich, Harald [Technische Univ. Muenchen, Garching (Germany). Physik-Department

    2013-08-01

    Written by the author of the widely acclaimed textbook. Theoretical Atomic Physics Includes sections on quantum reflection, tunable Feshbach resonances and Efimov states. Useful for advanced students and researchers. This book presents a concise and modern coverage of scattering theory. It is motivated by the fact that experimental advances have shifted and broadened the scope of applications where concepts from scattering theory are used, e.g. to the field of ultracold atoms and molecules, which has been experiencing enormous growth in recent years, largely triggered by the successful realization of Bose-Einstein condensates of dilute atomic gases in 1995. In the present treatment, special attention is given to the role played by the long-range behaviour of the projectile-target interaction, and a theory is developed, which is well suited to describe near-threshold bound and continuum states in realistic binary systems such as diatomic molecules or molecular ions. The level of abstraction is kept as low as at all possible, and deeper questions related to mathematical foundations of scattering theory are passed by. The book should be understandable for anyone with a basic knowledge of nonrelativistic quantum mechanics. It is intended for advanced students and researchers, and it is hoped that it will be useful for theorists and experimentalists alike.

    Based on the studies of floating-reference theory(FRT) applied to non-invasive optical blood glucose sensing, this paper further investigated the availability of FRT in measuring other blood compo-nents, like bilirubin. According to the conditions of the radial reference location, the results of Monte Carlo simulation show no appearance of radial reference location in non-invasive bilirubin measurement. While the study on the replacement effect of bilirubin and water shows that, at the wavelength of 524 run, the absorption value of bilirubin solution has no relationship with its concentration. Therefore, this wave-length is regarded as the reference wavelength, and in the further study, it can be used to remove the in-fluence caused by the change of environment and background. In general, the application of FRT in blood glucose and bilirubin shows the specificity of floating reference location and floating reference wave-length in measuring different blood components by optical technology within the designated wavelength, which further improves and extends the application of FRT.%在浮动基准理论(FRT)应用于血糖无创光学检测研究成果的基础上,进一步研究其在其他血液成分(如胆红素)无创光学检测中的适用性.根据径向检测基准位置存在的条件,经蒙特卡洛模拟的结果表明胆红素测量中难以找到浮动基准位置;而通过研究胆红素与水的置换效应,发现在波长524 nm处吸光度值与胆红素的浓度无关,将该波长作为基准波长,实际测量中可以用于去除背景噪声和环境干扰.综合FRT在血糖及胆红素两种不同血液成分中应用的研究结果表明:对于不同检测成分,在相应的检测波段,浮动基准位置和浮动基准波长有一定的特异性,从而进一步完善和扩展了FRT的应用领域.

Communication is not simply an exchange of information, in which we have a sender and a receiver. This very technical concept of communication is clearly outdated; a human being...... is not a data processing device. In this chapter, communication is understood as a process of shared meaning-making (Bruner, 1990). Human beings interpret their environment, other people, and themselves on the basis of their dynamic interaction with the surrounding world. Meaning is essential because people...... ascribe specific meanings to their experiences, their actions in life or work, and their interactions. Meaning is reshaped, adapted, and transformed in every communication encounter. Furthermore, meaning is cocreated in dialogues or in communities of practice, such as in teams at a workplace or in school...

    Potential Theory presents a clear path from calculus to classical potential theory and beyond, with the aim of moving the reader into the area of mathematical research as quickly as possible. The subject matter is developed from first principles using only calculus. Commencing with the inverse square law for gravitational and electromagnetic forces and the divergence theorem, the author develops methods for constructing solutions of Laplace's equation on a region with prescribed values on the boundary of the region. The latter half of the book addresses more advanced material aimed at those with the background of a senior undergraduate or beginning graduate course in real analysis. Starting with solutions of the Dirichlet problem subject to mixed boundary conditions on the simplest of regions, methods of morphing such solutions onto solutions of Poisson's equation on more general regions are developed using diffeomorphisms and the Perron-Wiener-Brelot method, culminating in application to Brownian motion.

    This book was written to serve as the standard textbook of elastoplasticity for students, engineers and researchers in the field of applied mechanics. The present second edition is improved thoroughly from the first edition by selecting the standard theories from various formulations and models, which are required to study the essentials of elastoplasticity steadily and effectively and will remain universally in the history of elastoplasticity. It opens with an explanation of vector-tensor analysis and continuum mechanics as a foundation to study elastoplasticity theory, extending over various strain and stress tensors and their rates. Subsequently, constitutive equations of elastoplastic and viscoplastic deformations for monotonic, cyclic and non-proportional loading behavior in a general rate and their applications to metals and soils are described in detail, and constitutive equations of friction behavior between solids and its application to the prediction of stick-slip phenomena are delineated. In additi...

    CERN Document Server

    2015-01-01

    A one-sentence definition of operator theory could be: The study of (linear) continuous operations between topological vector spaces, these being in general (but not exclusively) Fréchet, Banach, or Hilbert spaces (or their duals). Operator theory is thus a very wide field, with numerous facets, both applied and theoretical. There are deep connections with complex analysis, functional analysis, mathematical physics, and electrical engineering, to name a few. Fascinating new applications and directions regularly appear, such as operator spaces, free probability, and applications to Clifford analysis. In our choice of the sections, we tried to reflect this diversity. This is a dynamic ongoing project, and more sections are planned, to complete the picture. We hope you enjoy the reading, and profit from this endeavor.

    This corrected and updated second edition of "Scattering Theory" presents a concise and modern coverage of the subject. In the present treatment, special attention is given to the role played by the long-range behaviour of the projectile-target interaction, and a theory is developed, which is well suited to describe near-threshold bound and continuum states in realistic binary systems such as diatomic molecules or molecular ions. It is motivated by the fact that experimental advances have shifted and broadened the scope of applications where concepts from scattering theory are used, e.g. to the field of ultracold atoms and molecules, which has been experiencing enormous growth in recent years, largely triggered by the successful realization of Bose-Einstein condensates of dilute atomic gases in 1995. The book contains sections on special topics such as near-threshold quantization, quantum reflection, Feshbach resonances and the quantum description of scattering in two dimensions. The level of abstraction is k...

  6. Communication, Technology, Temporality

    Directory of Open Access Journals (Sweden)

    Mark A. Martinez

    2012-08-01

    Full Text Available This paper proposes a media studies that foregrounds technological objects as communicative and historical agents. Specifically, I take the digital computer as a powerful catalyst of crises in communication theories and certain key features of modernity. Finally, the computer is the motor of “New Media” which is at once a set of technologies, a historical epoch, and a field of knowledge. As such the computer shapes “the new” and “the future” as History pushes its origins further in the past and its convergent quality pushes its future as a predominate medium. As treatment of information and interface suggest, communication theories observe computers, and technologies generally, for the mediated languages they either afford or foreclose to us. My project describes the figures information and interface for the different ways they can be thought of as aspects of communication. I treat information not as semantic meaning, formal or discursive language, but rather as a physical organism. Similarly an interface is not a relationship between a screen and a human visual intelligence, but is instead a reciprocal, affective and physical process of contact. I illustrate that historically there have been conceptions of information and interface complimentary to mine, fleeting as they have been in the face of a dominant temporality of mediation. I begin with a theoretically informed approach to media history, and extend it to a new theory of communication. In doing so I discuss a model of time common to popular, scientific, and critical conceptions of media technologies especially in theories of computer technology. This is a predominate model with particular rules of temporal change and causality for thinking about mediation, and limits the conditions of possibility for knowledge production about communication. I suggest a new model of time as integral to any event of observation and analysis, and that human mediation does not exhaust the

    This book deals with the basic subjects of design theory. It begins with balanced incomplete block designs, various constructions of which are described in ample detail. In particular, finite projective and affine planes, difference sets and Hadamard matrices, as tools to construct balanced incomplete block designs, are included. Orthogonal latin squares are also treated in detail. Zhu's simpler proof of the falsity of Euler's conjecture is included. The construction of some classes of balanced incomplete block designs, such as Steiner triple systems and Kirkman triple systems, are also given.

    Goldie, Charles M

    1991-01-01

    This book is an introduction, for mathematics students, to the theories of information and codes. They are usually treated separately but, as both address the problem of communication through noisy channels (albeit from different directions), the authors have been able to exploit the connection to give a reasonably self-contained treatment, relating the probabilistic and algebraic viewpoints. The style is discursive and, as befits the subject, plenty of examples and exercises are provided. Some examples and exercises are provided. Some examples of computer codes are given to provide concrete illustrations of abstract ideas.

  19. An age structured demographic model of technology

    CERN Document Server

    Mercure, J -F

    2013-01-01

    At the heart of technology transitions lie complex processes of technology choices. Understanding and planning sustainability transitions requires modelling work, which necessitates a theory of technology substitution. A theoretical model of technological change and turnover is presented, intended as a methodological paradigm shift from widely used conventional modelling approaches such as cost optimisation. It follows the tradition of evolutionary economics and evolutionary game theory, using ecological population growth dynamics to represent the evolution of technology populations in the marketplace, with substitutions taking place at the level of the decision-maker. Extended to use principles of human demography or the age structured evolution of species in interacting ecosystems, this theory is built from first principles, and through an appropriate approximation, reduces to a form identical to empirical models of technology diffusion common in the technology transitions literature. Using an age structure...
