    2008-01-01

    This paper is about intellectual property rights (IPRs) and platform technologies. After a brief introduction explaining some basics of networks, standards and platforms, I turn to three policy issues. The first is the role of IP in what might be termed platform policies, the decisions by courts and regulators concerning whether and how to promote multi-party access to important digital platforms such as media player hardware, cell phones, PCs, and the like. I argue that for the most part the...

  9. Genetic enhancement, human nature, and rights.

    Science.gov (United States)

    McConnell, Terrance

    2010-08-01

    Authors such as Francis Fukuyama, the President's Council on Bioethics, and George Annas have argued that biotechnological interventions that aim to promote genetic enhancement pose a threat to human nature. This paper clarifies what conclusions these critics seek to establish, and then shows that there is no plausible account of human nature that will meet the conditions necessary to support this position. Appeals to human nature cannot establish a prohibition against the pursuit of genetic enhancement.

  10. Policy implications of technologies for cognitive enhancement

    Energy Technology Data Exchange (ETDEWEB)

    Sarewitz, Daniel R. (Arizona State University, Tempe, AZ); Karas, Thomas H.

    2007-02-01

    The Advanced Concepts Group at Sandia National Laboratory and the Consortium for Science, Policy and Outcomes at Arizona State University convened a workshop in May 2006 to explore the potential policy implications of technologies that might enhance human cognitive abilities. The group's deliberations sought to identify core values and concerns raised by the prospect of cognitive enhancement. The workshop focused on the policy implications of various prospective cognitive enhancements and on the technologies/nanotechnology, biotechnology, information technology, and cognitive science--that enable them. The prospect of rapidly emerging technological capabilities to enhance human cognition makes urgent a daunting array of questions, tensions, ambitions, and concerns. The workshop elicited dilemmas and concerns in ten overlapping areas: science and democracy; equity and justice; freedom and control; intergenerational issues; ethics and competition; individual and community rights; speed and deliberations; ethical uncertainty; humanness; and sociocultural risk. We identified four different perspectives to encompass the diverse issues related to emergence of cognitive enhancement technologies: (1) Laissez-faire--emphasizes freedom of individuals to seek and employ enhancement technologies based on their own judgment; (2) Managed technological optimism--believes that while these technologies promise great benefits, such benefits cannot emerge without an active government role; (3) Managed technological skepticism--views that the quality of life arises more out of society's institutions than its technologies; and (4) Human Essentialism--starts with the notion of a human essence (whether God-given or evolutionary in origin) that should not be modified. While the perspectives differ significantly about both human nature and the role of government, each encompasses a belief in the value of transparency and reliable information that can allow public discussion and

    2015-01-01

    Innovation in medical technology generates a remarkable supply of new drugs, devices, and diagnostics that improve health, reduce risks, and extend life. But these technologies are too often used on the wrong patient, in the wrong setting, or at an unaffordable price. The only way to moderate the growth in health care costs without undermining the dynamic of medical innovation is to improve the process of assessing, pricing, prescribing, and using new technologies. Purchasing Medical Innovation analyzes the contemporary revolution in the purchasing of health care technology, with a focus on th

  13. Quartz-Enhanced Photoacoustic Spectroscopy with Right-Angle Prism

    Directory of Open Access Journals (Sweden)

    Yongning Liu

    2016-02-01

    Full Text Available A right-angle prism was used to enhance the acoustic signal of a quartz-enhanced photoacoustic spectroscopy (QEPAS system. The incident laser beam was parallelly inverted by the right-angle prism and passed through the gap between two tuning fork prongs again to produce another acoustic excitation. Correspondingly, two pairs of rigid metal tubes were used as acoustic resonators with resonance enhancement factors of 16 and 12, respectively. The QEPAS signal was enhanced by a factor of 22.4 compared with the original signal, which was acquired without resonators or a prism. In addition, the system noise was reduced a little with double resonators due to the Q factor decrease. The signal-to-noise ratio (SNR was greatly improved. Additionally, a normalized noise equivalent absorption coefficient (NNEA of 5.8 × 10−8 W·cm−1·Hz−1/2 was achieved for water vapor detection in the atmosphere.

  1. Disability rights, reproductive technology, and parenthood: unrealised opportunities.

    Science.gov (United States)

    Rothler, Roni

    2017-05-01

    The common attitude towards parents with disabilities is suspicious. Whereas usually, people are expected to become parents as part of a natural-social life course, disability and parenthood are conceived as contradicting terms. This is due to negative perceptions regarding the parenting capacity of people with disabilities, and lack of adequate state support for children upbringing. Disability Rights theories portray different approaches, aiming to promote equality, considering the unique life experiences of parents with disabilities. They acknowledge the discrimination that takes place whenever accommodations are denied, and they bring a universal point of view to light. Through the case of Ora Mor-Yosef, a woman with a severe physical disability who initiated the birth of a baby girl, with no genetic connection to her, the article wishes to demonstrate the potential contribution of reproductive technology, combined with legal parenthood developments, and disability studies theories, to the advancement of parenting rights and opportunities for persons with disabilities. Regrettably, Ora's case did not serve as a platform for such promotion. "Social disability obstacles", suspicion, and negative attitudes that still prevail regarding parents with disabilities, have led both the government authorities and the courts to deny Ora's attempt to accommodate reproductive technological processes and become a mother.

  4. Technologies and countermeasures for gas recovery enhancement

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available Since 2000, China has been ranked as one of the top countries in gas production. Nevertheless, the domestic gas production can hardly satisfy the need of national economic development. Besides, an increasing number of gas fields have come to the middle or late development stages, and most gas reservoirs have low recovery efficiency due to the low permeability and water drive nature. Therefore, gas recovery enhancement has become an urgent issue. At present, the oil recovery enhancement is well defined, and there are methods describing the remaining oil and a complete set of mature EOR (enhanced oil recovery technologies. However, the definition and description of EGR (enhanced gas recovery are still undermined, and the description method for the distribution of residual gas and EGR technologies are almost unavailable. In view of this, by reviewing a wealth of related literatures, we defined EGR and also described the remaining gas distribution based on the remaining gas abundance. In addition, collecting three typical types (low-permeability, condensate and edge/bottom water of major gas reservoirs developed both at home and abroad, we summarized the geological and development characteristics, and found out the obstructions in the development. In response, we concluded and analyzed the relevant technologies and methods for enhancing the gas recovery of such reservoirs, and proposed the suggestions about EGR technology development, which provides a significant reference and popularization basis for EGR measures in fields.

    E-Learning has become one of the most wide spread ways of distance teaching and learning. Technologies such as Web, Grid, and Mobile and Wireless networks are pushing teaching and learning communities to find new and intelligent ways of using these technologies to enhance teaching and learning activities. Indeed, these new technologies can play an important role in increasing the support to teachers and learners, to shorten the time to learning and teaching; yet, it is necessary to use intelligent techniques to take advantage of these new technologies to achieve the desired support to teachers and learners and enhance learners' performance in distributed learning environments. The chapters of this volume bring advances in using intelligent techniques for technology enhanced learning as well as development of e-Learning applications based on such techniques and supported by technology. Such intelligent techniques include clustering and classification for personalization of learning, intelligent context-aware techniques, adaptive learning, data mining techniques and ontologies in e-Learning systems, among others. Academics, scientists, software developers, teachers and tutors and students interested in e-Learning will find this book useful for their academic, research and practice activity. (orig.)

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

  20. Enhanced Attenuation Technologies: Passive Soil Vapor Extraction

    Energy Technology Data Exchange (ETDEWEB)

    Vangelas, K.; Looney, B.; Kamath, R.; Adamson, D.; Newell, C.

    2010-03-15

    Passive soil vapor extraction (PSVE) is an enhanced attenuation (EA) approach that removes volatile contaminants from soil. The extraction is driven by natural pressure gradients between the subsurface and atmosphere (Barometric Pumping), or by renewable sources of energy such as wind or solar power (Assisted PSVE). The technology is applicable for remediating sites with low levels of contamination and for transitioning sites from active source technologies such as active soil vapor extraction (ASVE) to natural attenuation. PSVE systems are simple to design and operate and are more cost effective than active systems in many scenarios. Thus, PSVE is often appropriate as an interim-remedial or polishing strategy. Over the past decade, PSVE has been demonstrated in the U.S. and in Europe. These demonstrations provide practical information to assist in selecting, designing and implementing the technology. These demonstrations indicate that the technology can be effective in achieving remedial objectives in a timely fashion. The keys to success include: (1) Application at sites where the residual source quantities, and associated fluxes to groundwater, are relatively low; (2) Selection of the appropriate passive energy source - barometric pumping in cases with a deep vadose zone and barrier (e.g., clay) layers that separate the subsurface from the atmosphere and renewable energy assisted PSVE in other settings and where higher flow rates are required. (3) Provision of sufficient access to the contaminated vadose zones through the spacing and number of extraction wells. This PSVE technology report provides a summary of the relevant technical background, real-world case study performance, key design and cost considerations, and a scenario-based cost evaluation. The key design and cost considerations are organized into a flowchart that dovetails with the Enhanced Attenuation: Chlorinated Organics Guidance of the Interstate Technology and Regulatory Council (ITRC).

    2012-06-01

    Full Text Available The range of technologies available to support teaching and learning in higher education continues to grow exponentially. There is a growing expectation for educators to be well informed and familiar with the many suitable technologies and systems that are available to be used for delivering courses online, and to complement classroom (face-to-face education. Detailed evidence of the perceptions and applications of the use of e-technologies is needed to inform not only teaching practice, but also policy development. These e-technologies need to be matched to pedagogical styles in order for online teaching and learning to be successful. Based on 33 semi-structured interviews, this paper presents a study of staff experiences of e-technologies, using Chickering and Gamson's 'Seven Principles of Good Practice' to provide educators with information about the most appropriate e-technology to support their pedagogical aims.

  2. Solar technology application to enhanced oil recovery

    Energy Technology Data Exchange (ETDEWEB)

    de Leon, P.; Brown, K.C.; Margolis, J.W.; Nasr, L.H.

    1979-12-01

    One proposed near-term commercial application for solar energy technology is the use of solar energy systems to generate steam for thermal enhanced oil recovery (EOR). This report examines four aspects of solar energy employed for steam EOR. First, six solar technologies are evaluated and two - parabolic troughs and central receivers - are selected for closer study; typical systems that would meet current production requirements are proposed and costed. Second, the legal and environmental issues attending solar EOR are analyzed. Third, the petroleum producing companies' preferences and requirements are discussed. Finally, alternative means of financing solar EOR are addressed. The study concludes that within the next four to five years, conventional (fossil-fueled) thermal EOR means are much less expensive and more available than solar EOR systems, even given environmental requirements. Within 10 to 15 years, assuming specified advances in solar technologies, central receiver EOR systems will be significantly more cost-effective than parabolic trough EOR systems and will be price competitive with conventional thermal EOR systems.

    This article provides an overview of different types of rights to aid consideration of, and debate about, children and young people's rights in the context of paediatrics and child health. It demonstrates how children's rights may or may not differ from adult rights and the implications for practice. It shows that applying a children's rights framework can be more helpful in pursuing a public child health agenda than in reducing ethical or legal conflicts when interacting with child patients and their families.

    Full Text Available On December 10, 1948 the General Assembly of the United Nations adopted and proclaimed the Universal Declaration of Human Rights. Article 26 of that declaration deals with the right to education. Its three clauses are: 1. Everyone has the right to education. Education shall be free, at least in the elementary and fundamental stages. Elementary education shall be compulsory. Technical and professional education shall be made generally available and higher education shall be equally accessible to all on the basis of merit. 2. Education shall be directed to the full development of the human personality and to the strengthening of respect for human rights and fundamental freedoms. It shall promote understanding, tolerance and friendship among all nations, racial or religious groups, and shall further the activities of the United Nations for the maintenance of peace. 3. Parents have a prior right to choose the kind of education that shall be given to their children.Almost 60 years have passed since this declaration. In that time, distance education has emerged as a way of extending educational opportunities to those for whom poverty, remote location, gender, disability, or dislocation has made education more of a luxury than a right, especially in the world’s poverty zones. At basic and secondary levels, open schools and classrooms are using distance education approaches to help universalize primary education and make secondary education at least a possibility for those who would otherwise become permanent school leavers (cf. Yates & Bradley, 2000, and Bradley, 2003. Perraton estimated that as many as 20 per cent of university students in developing countries were studying at a distance, compared with 12 per cent in industrialized countries (2000. Those percentages, no doubt, are considerably higher today. Nonetheless, 72 million children remain out of school, one in five adults is without basic literacy skills, and many pupils leave school without

  11. Recalibrating intellectual property rights to enhance translational research collaborations.

    Science.gov (United States)

    Bubela, Tania; FitzGerald, Garret A; Gold, E Richard

    2012-02-22

    Multisectoral collaborative models for drug and therapeutic research and development (R&D) are emerging, requiring a recalibration of how intellectual property rights (IPRs) are used. Although these models appear promising, little study has been conducted on the optimal blend of sharing and exclusion as mediated through the proactive use or nonuse of IPRs. This Commentary is a call for a combination of theoretical and empirical analyses to build a comprehensive understanding of the interplay between formal IP laws, institutions that administer and manage IPRs, and the use of IPRs in practice to better construct and manage collaborations. Such analyses require outcome metrics formulated to measure the success of therapeutic outcomes and to capture the complexity of a highly networked R&D environment.

    Animal welfare is receiving increasing attention from the authorities, the public and NGOs. For this reason, the improvement of animal welfare and animal handling systems is of the utmost importance for the meat industry. Technological developments have led to more animal friendly systems that handle animals on the day of slaughter, and these developments will be even more important as consideration for animal welfare and sustainability is no longer just a trend but a licence to operate. Improvement of animal welfare also leads to a higher value of the carcasses due to higher product quality, less cut-off caused by fewer injuries, and reduced working load, which leads to increased business opportunities. Therefore, good animal welfare is good business, and the development and implementation of new technology is the way to obtain improved animal welfare. These subjects will be addressed using examples and cases from the pork and broiler production industry.

    Full Text Available This paper deals with the important topic of human enhancement and tries to focus the question under a new perspective. The international debate is focused around two main theoretical positions: bio-conservatorism and techno-enthusiasm. We seem to be forced to choose one or another conception in order to understand the relationship between human beings and technology. The first part of the paper analyzes different authors trying to circumscribe the principal features of each one. We can notice two main paradigms which are incapable to rightly understand the phenomenon we are considering. The relieves emerging in the first part will be suitable to prosecute the analysis in the second part of the work.

  20. A Thomistic appraisal of human enhancement technologies.

    Science.gov (United States)

    Eberl, Jason T

    2014-08-01

    Debate concerning human enhancement often revolves around the question of whether there is a common "nature" that all human beings share and which is unwarrantedly violated by enhancing one's capabilities beyond the "species-typical" norm. I explicate Thomas Aquinas's influential theory of human nature, noting certain key traits commonly shared among human beings that define each as a "person" who possesses inviolable moral status. Understanding the specific qualities that define the nature of human persons, which includes self-conscious awareness, capacity for intellective thought, and volitional autonomy, informs the ethical assessment of various forms of enhancement. Some forms of cognitive and physical enhancement may be desirable from the perspective of what constitutes the "flourishing" of human persons in our fundamental nature; while other forms of enhancement, such as emotive or so-called "moral" enhancement, run the risk of detracting from human flourishing when evaluated from the virtue-theoretic perspective Aquinas promotes.

    The objective of this project was to develop a sonic well performance enhancement technology that focused on near wellbore formation damage. In order to successfully achieve this objective, a three-year project was defined. The entire project was broken into four tasks. The overall objective of all this was to foster a better understanding of the mechanisms involved in sonic energy interactions with fluid flow in porous media and adapt such knowledge for field applications. The fours tasks are: • Laboratory studies • Mathematical modeling • Sonic tool design and development • Field demonstration The project was designed to be completed in three years; however, due to budget cuts, support was only provided for the first year, and hence the full objective of the project could not be accomplished. This report summarizes what was accomplished with the support provided by the US Department of Energy. Experiments performed focused on determining the inception of cavitation, studying thermal dissipation under cavitation conditions, investigating sonic energy interactions with glass beads and oil, and studying the effects of sonication on crude oil properties. Our findings show that the voltage threshold for onset of cavitation is independent of transducer-hydrophone separation distance. In addition, thermal dissipation under cavitation conditions contributed to the mobilization of deposited paraffins and waxes. Our preliminary laboratory experiments suggest that waxes are mobilized when the fluid temperature approaches 40°C. Experiments were conducted that provided insights into the interactions between sonic wave and the fluid contained in the porous media. Most of these studies were carried out in a slim-tube apparatus. A numerical model was developed for simulating the effect of sonication in the nearwellbore region. The numerical model developed was validated using a number of standard testbed problems. However, actual application of the model for scale

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

    2009-08-01

    This article examines the high prevalence of primary and secondary infertility in low-resource countries. Provision of assisted reproductive technology (ART) to overcome both female and male infertility is in line with the reproductive rights agenda developed at the International Conference on Population and Development (ICPD) in Cairo 15 years ago. In addition to the right to control fertility, reproductive rights must encompass the right to facilitate fertility when fertility is threatened. Facilitation of fertility may require resort to ART, among both men and women. Egypt is highlighted as a positive example of progress in this regard.

  8. Cost studies of thermally enhanced in situ soil remediation technologies

    Energy Technology Data Exchange (ETDEWEB)

    Bremser, J.; Booth, S.R.

    1996-05-01

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

  11. Late Gadolinium Enhancement of the right ventricular myocardium: Is it really different from the left ?

    Directory of Open Access Journals (Sweden)

    Macgowan Christopher K

    2008-05-01

    Full Text Available Abstract It has been suggested that, in late gadolinium enhancement, the signal of right ventricular myocardium is nulled at a shorter inversion time than the left. While we initially made the same observation, we believe that the difference is not real, but results from artifacts. We present 7 cases as well as computer simulations to describe the nature of these artifacts and explain how they can create the impression of different inversion times for the right and left ventricle. At inversion times that are shorter than ideal for the myocardium a black rim can be seen at the border of the myocardium with blood on the inside and with fat on the outside. This is most likely a partial volume effect. The thin myocardium of the right ventricle is sandwiched between these black rims and, at a low spatial resolution, is no longer visible. In this case, the adjacent black rims may then be misinterpreted as myocardium. While black rims also occur on the left side, the myocardium is thicker and remains discernable as a separate layer. As a consequence, the optimal inversion time for the right ventricle only appears different from that for the left. In fact, in the presence of hypertrophy of the right ventricle or during systolic wall thickening we did not find a difference in inversion times between the left and right ventricle. We conclude that sufficient spatial resolution is important for adequate late gadolinium enhancement of the right ventricle.

    Moreland, Judy; Jones, Alister; Northover, Ann

    2001-02-01

    This paper reports on a two-year classroom investigation of primary school (Years 1-8) technology education. The first year of the project explored emerging classroom practices in technology. In the second year intervention strategies were developed to enhance teaching, learning and assessment practices. Findings from the first year revealed that assessment was often seen in terms of social and managerial aspects, such as teamwork, turn taking and co-operative skills, rather than procedural and conceptual technological aspects. Existing formative interactions with students distorted the learning away from the procedural and conceptual aspects of the subject. The second year explored the development of teachers' technological knowledge in order to enhance formative assessment practices in technology, to inform classroom practice in technology, and to enhance student learning. Intervention strategies were designed to enhance the development of procedural, conceptual, societal and technical aspects of technology for teachers and students. The results from this intervention were very positive. This paper highlights the importance of developing teacher expertise pertaining to broad concepts of technology, detailed concepts in different technological areas and general pedagogical knowledge. The findings from this research therefore have implications for thinking about teaching, learning and assessment in technology.

  1. New technologies of enhanced oil recovery

    Directory of Open Access Journals (Sweden)

    Paweł Wojnarowski

    2006-10-01

    Full Text Available It is known from the literature that up to 27 % of oil in oilfields can be produced using primary and hydration methods. The efficiency of production can be increased by employing more advanced methods, i.e. EOR. The Polish Oil and Gas Company iwork with Polish oilfields, where currently primary methods are applied, but the Polish experiences with EOR date back to the years 1932-1987. In view of high oil prices, reconsidering EOR as a production method is economically justifiable. Therefore, it is purposeful to implement new pilot technologies, aimed at implementing new technologies, understanding accompanying phenomena, and calibrating of simulation models, including economical models for an optimal control of the oilfield exploitation. World’s new exploitation methods worked out in the last few years and suggestions for their implementation in Polish conditions are presented in the paper

    Objective Suicide prevention is a high priority. Scalable and sustainable interventions for suicide prevention are needed to set the stage for population-level impact. This systematic review explores how technology-enhanced interventions target suicide risk and protective factors, using the Centers for Disease Control and Prevention (CDC, 2015) Risk and Protective Factors Ecological Model. Methods Information databases (PsycINFO, PubMed and CINAHL) were systematically searched and records including technology-enhanced interventions for suicide prevention ( n = 3764) were reviewed. Records with varying technologies and diverse methodologies were integrated into the search. Results Review of the records resulted in the inclusion of 16 studies that utilized technology-enhanced interventions to address determinants of suicidal behaviour. This includes the use of standalone or, in most cases, adjunct technology-enhanced interventions for suicide prevention delivered by mobile phone application, text message, telephone, computer, web, CD-ROM and video. Conclusion Intervention effectiveness was variable, but several technology-enhanced interventions have demonstrated effectiveness in reducing suicidal ideation and mental health co-morbidities. Large-scale research and evaluation initiatives are needed to evaluate the costs and long-term population-level impact of these interventions.

  7. Moral Enhancement by Technological Means: Possible, Permissible, a Duty?

    Full Text Available Attempts to enhance individual and communal morality are as old as human communal living itself. But only recently have philosophers, bioethicists and scientists begun to seriously consider the possibilities and implications of employing technological interventions into the human body, especially the brain, in order to enhance traits and capabilities that underlie what we might term as moral reasoning, action and behavior. Some illicit drugs, prescription pharmaceuticals and non-invasive brain stimulation techniques have been shown to have effects on diminishing or enhancing certain of our mental traits that constitute moral thinking, action and behavior in healthy adults. This hints at the possibility of targeted interventions that might predictably improve individual and communal morality and through it societal cooperation. The first part of the paper will delve into some of the conceptual issues connected with moral enhancement as part of the broader trend of cognitive enhancement and human enhancement in general. The second part will look at some experiments and interventions that support the plausibility of technologically enhancing moral reasoning and moral behavior. The third part will present some of the arguments that have been written both for and against moral enhancement, including whether we might in certain situations have a duty to morally enhance ourselves. The final part looks at some further dilemmas of whether we might already be enhancing ourselves morally through some commonly prescribed pharmaceutical drugs, and what a (further "medicalization" of moral deficits might mean.

  8. Miniaturized Technologies for Enhancement of Motor Plasticity

    2016-04-01

    Full Text Available The idea that the damaged brain can functionally reorganize itself ⎯ so when one part fails, there lies the possibility for another to substitute ⎯ is an exciting discovery of the twentieth century. We now know that motor circuits once presumed to be hardwired are not, and motor-skill learning, exercise, and even mental rehearsal of motor tasks can turn genes on or off to shape brain architecture, function and, consequently, behavior. This is a very significant alteration from our previously static view of the brain, and has profound implications for the rescue of function after a motor injury. Presentation of the right cues, applied in relevant spatiotemporal geometries, is required to awaken the dormant plastic forces essential for repair. The focus of this review is to highlight some of the recent progress in neural interfaces designed to harness motor plasticity, and the role of miniaturization in development of strategies that engage diverse elements of the neuronal machinery to synergistically facilitate recovery of function after motor damage.

    Critical thinking is acclaimed as a valuable asset for graduates from higher education programs. Technology has advanced in quantity and quality; recognized as a requirement of 21st century learners. A mixed methods research study was undertaken, examining undergraduate nursing student engagement with critical thinking instruction, platformed on two technology-enhanced learning environments: a classroom response system face-to-face in-class and an online discussion forum out-of-class. The Community of Inquiry framed the study capturing constructivist collaborative inquiry to support learning, and facilitate critical thinking capability. Inclusion of quantitative and qualitative data sources aimed to gather a comprehensive understanding of students' development of critical thinking and engagement with technology-enhanced learning. The findings from the students' perspectives were positive toward the inclusion of technology-enhanced learning, and use in supporting their development of critical thinking. Students considered the use of two forms of technology beneficial in meeting different needs and preferences, offering varied means to actively participate in learning. They valued critical thinking instruction being intentionally aligned with subject-specific content facilitating understanding, application, and relevance of course material. While the findings are limited to student participants, the instructional strategies and technology-enhanced learning identified as beneficial can inform course design for the development of critical thinking.

    This project inquired into the judgments and beliefs of people living near DOE reservations and facilities at Oak Ridge, Tennessee; Hanford, Washington; and Los Alamos, Tennessee about bioremediation of subsurface contamination. The purpose of the investigation was to identify strategies based on these judgments and beliefs for enhancing public support of bioremediation. Several methods were used to collect and analyze data including content analysis of transcripts of face-to-face personal interviews, factor analysis of subjective perspectives using Q methodology, and statistical analysis of results from a large-sample randomized telephone survey. Content analysis of interview transcripts identified themes about public perceptions and constructions of contamination risk, risk management, and risk managers. This analysis revealed that those who have no employment relationship at the sites and are not engaged in technical professions are most concerned about contamination risks. We also found that most interviewees are unfamiliar with subsurface contamination risks and how they can be reduced, believe they have little control over exposure, are frustrated with the lack of progress in remediation, are concerned about a lack of commitment of DOE to full remediation, and distrust site managers to act in the public interest. Concern is also expressed over frequent site management turnover, excessive secrecy, ineffective and biased communication, perceived attempts to talk the public into accepting risk, and apparent lack of concern about community welfare. In the telephone survey, we asked respondents who were aware of site contamination about their perceptions of risk from exposure to subsurface contamination. Response analysis revealed that most people believe that they are at significant risk from subsurface contamination but they acknowledge that more education is needed to calibrate risk perceptions against scientific risk assessments. Most rate their personal

  13. Performance-enhancing technologies and moral responsibility in the military.

    Wolfendale, Jessica

    2008-02-01

    New scientific advances have created previously unheard of possibilities for enhancing combatants' performance. Future war fighters may be smarter, stronger, and braver than ever before. If these technologies are safe, is there any reason to reject their use? In this article, I argue that the use of enhancements is constrained by the importance of maintaining the moral responsibility of military personnel. This is crucial for two reasons: the military's ethical commitments require military personnel to be morally responsible agents, and moral responsibility is necessary for integrity and the moral emotions of guilt and remorse, both of which are important for moral growth and psychological well-being. Enhancements that undermined combatants' moral responsibility would therefore undermine the military's moral standing and would harm combatants' well-being. A genuine commitment to maintaining the military's ethical standards and the well-being of combatants therefore requires a careful analysis of performance-enhancing technologies before they are implemented.

  14. Advanced Technologies For Stripper Gas Well Enhancement

    2005-04-01

    Stripper gas and oil well operators frequently face a dilemma regarding maximizing production from low-productivity wells. With thousands of stripper wells in the United States covering extensive acreage, it is difficult to identify easily and efficiently marginal or underperforming wells. In addition, the magnitude of reviewing vast amounts of data places a strain on an operator's work force and financial resources. Schlumberger DCS, in cooperation with the National Energy Technology Laboratory (NETL) and the U.S. Department of Energy (DOE), has created software and developed in-house analysis methods to identify remediation potential in stripper wells relatively easily. This software is referred to as Stripper Well Analysis Remediation Methodology (SWARM). SWARM was beta-tested with data pertaining to two gas fields located in northwestern Pennsylvania and had notable results. Great Lakes Energy Partners, LLC (Great Lakes) and Belden & Blake Corporation (B&B) both operate wells in the first field studied. They provided data for 729 wells, and we estimated that 41 wells were candidates for remediation. However, for reasons unbeknownst to Schlumberger these wells were not budgeted for rework by the operators. The second field (Cooperstown) is located in Crawford, Venango, and Warren counties, Pa and has more than 2,200 wells operated by Great Lakes. This paper discusses in depth the successful results of a candidate recognition study of this area. We compared each well's historical production with that of its offsets and identified 339 underperformers before considering remediation costs, and 168 economically viable candidates based on restimulation costs of $50,000 per well. From this data, we prioritized a list based on the expected incremental recoverable gas and 10% discounted net present value (NPV). For this study, we calculated the incremental gas by subtracting the volumes forecasted after remediation from the production projected at its current

    The paper introduces an approach to privacy enhancing technologies that sees privacy not merely as an individual right, but as a public good. This idea finds its correspondence in our approach to privacy protection through obfuscation, where everybody in a group takes a small privacy risk to protect the anonymity of fellow group members. We show how these ideas can be computationally realised in an Investigative Data Acquisition Platform (IDAP). IDAP is an efficient symmetric Private Informat...

    Realization of EGS development would make geothermal a significant contender in the renewable energy portfolio, on the order of 100+ GWe in the United States alone. While up to 90% of the geothermal power resource in the United States is thought to reside in Enhanced Geothermal Systems (EGS), hurdles to commercial development still remain. The Geothermal Technologies Office, U.S. Department of Energy (DOE), began in 2011 to outline opportunities for advancing EGS technologies on five- to 20-year timescales, with community input on the underlying technology needs that will guide research and ultimately determine commercial success for EGS. This report traces DOE's research investments, past and present, and ties them to these technology needs, forming the basis for an EGS Technology Roadmap to help guide future DOE research. This roadmap is currently open for public comment. Send your comments to geothermal@ee.doe.gov.

    2015-12-01

    The orbitofrontal cortex (OFC) has been implicated in the capacity to accurately recognise facial expressions. The aim of the current study was to determine if anodal transcranial direct current stimulation (tDCS) targeting the right OFC in healthy adults would enhance facial expression recognition, compared with a sham condition. Across two counterbalanced sessions of tDCS (i.e. anodal and sham), 20 undergraduate participants (18 female) completed a facial expression labelling task comprising angry, disgusted, fearful, happy, sad and neutral expressions, and a control (social judgement) task comprising the same expressions. Responses on the labelling task were scored for accuracy, median reaction time and overall efficiency (i.e. combined accuracy and reaction time). Anodal tDCS targeting the right OFC enhanced facial expression recognition, reflected in greater efficiency and speed of recognition across emotions, relative to the sham condition. In contrast, there was no effect of tDCS to responses on the control task. This is the first study to demonstrate that anodal tDCS targeting the right OFC boosts facial expression recognition. This finding provides a solid foundation for future research to examine the efficacy of this technique as a means to treat facial expression recognition deficits, particularly in individuals with OFC damage or dysfunction.

  10. Motivationally significant self-control: enhanced action withholding involves the right inferior frontal junction.

    O'Connor, David A; Upton, Daniel J; Moore, Jennifer; Hester, Robert

    2015-01-01

    In everyday life, people use self-control to withhold actions. This ability is particularly important when the consequences of action withholding have an impact on the individual's well-being. Despite its importance, it is unclear as to how the neural nodes implicated in action withholding contribute to this real-world type of self-control. By modifying an action withholding paradigm, the go/no-go task, we examined how the brain exerts self-control during a scenario in which the implications of withholding an action are meaningful and motivationally significant. A successfully withheld response contributed to long-term monetary rewards, whereas failure to withhold a response incurred an immediate monetary punishment. Compared with neutral action withholding, participants significantly improved their performance when these contingencies were applied. Crucially, although the right IFG and pre-SMA were found to promote overall action withholding, the enhancement in behavioral performance relative to a neutral condition was only reflected by a physiological change in a region encompassing the right inferior frontal junction and precentral gyrus. We speculate that the ability to flexibly modulate attention to goal-relevant stimuli is crucial to enhanced, motivationally driven action withholding and that this ability is subserved by the right inferior frontal junction. These findings suggest that control-modulating factors, rather than action withholding processes per se, can be critical to improving motivationally significant action withholding outcomes.

    Plasma-assisted pulverized coal combustion is a promising technology for thermal power plants (TPP). This article reports one- and three- dimensional numerical simulations, as well as laboratory and industrial measurements of coal combustion using a plasma-fuel system (PFS). The chemical kinetic and fluid mechanics involved in this technology are analysed. The results show that a PFS, can be used to promote early ignition and enhanced stabilization of a pulverized coal flame. It is shown that this technology, in addition to enhancing the combustion efficiency of the flame, reduces harmful emissions from power coals of all ranks (brown, bituminous, anthracite and their mixtures). Data summarising the experience of 27 pulverized coal boilers in 16 thermal power plants in several countries (Russia, Kazakhstan, Korea, Ukraine, Slovakia, Mongolia and China), embracing steam productivities from 75 to 670 tons per hour (TPH), are presented. Finally, the practical computation of the characteristics of the PFS, as function of coal properties, is discussed.

    Science.gov (United States)

    Burns, W. C. G.

    2016-12-01

    The new Paris Agreement under the United Nations Framework Convention on Climate Change contemplates that its prospective Parties will balance emissions and sinks by 2050 as a means to effectuate the goal of holding temperature increases to well below 2°C from pre-industrial levels, as well as the more aspirational goal of holding temperature increases to 1.5°C. Most of the IPCC's AR5 scenarios that achieve these objectives contemplate the large-scale deployment of so-called "negative emissions technologies," with an emphasis on bioenergy and carbon capture and storage (BECCS), and to a lesser degree afforestation. BECCS could assuredly help society avoid passing critical climatic thresholds, or address overshoot scenarios in this century and beyond. However, it could also profound implications for food production, the status of forests, access to lands for livelihoods by vulnerable populations, and the integrity of critical ecosystems. This, in turn could have serious ramifications for human rights of some of the world's most vulnerable populations, including the rights to food, water, livelihoods and the benefits of biodiversity. The Preamble to the Paris Agreement acknowledges the need to take into consideration the potential impact of responses to climate change, providing that "Parties should, when taking action to address climate change, respect, promote and consider their respective obligations on human rights." This presentation will outline how application of a human rights-based approach to assessing such options could help to reconcile the objectives of ameliorating potential climatic impacts while protecting the human rights of potentially affected individuals and groups. This will include the potential role of Human Rights Impacts Assessments and potential configuration of HRIAs at the national and international level. It will also briefly suggest how to operationalize this approach within the Paris Agreement framework, including institutional

    2016-11-24

    Some university schools of nursing in Australia and the UK have developed collaborative links with Malaysia to deliver part-time Transnational Higher Education (TNHE) post-registration top-up nursing degree courses. It enables nurses trained to diploma level to upgrade to a degree qualification. The views of 18 Malaysian nurses who had studied with one Australian and two UK TNHE universities were explored using a hermeneutic phenomenological approach. Participants recruited via convenience and snowball sampling methods were interviewed in English and Bahasa Malaysia (Malaysian language). Thematic analysis were used to analyse data. Findings indicated nurses' frustration with technology-enhanced teaching and learning and a lack of support throughout the programme. Although nurses developed confidence in using computer technology, they remained disappointed with the level of academic support. The data and some useful strategies outlined provide important insights for TNHE providers, the Malaysian Nursing Board and private hospital employers to consider for enhancing nurses learning and experiences.

    Contribution of Micro-Small and Medium Enterprises (MSMEs) is highly remarkable in the overall industrial economy of the country. In recent years, the MSME sector has consistently registered higher growth rate compared to the overall industrial sector. With its agility and dynamism, the sector has shown admirable innovativeness and adaptability to survive the recent economic downturn and recession. However, MSMEs growth rate is still at low level. Therefore, it becomes essential for organizations to adopt new technologies or upgrade existing setup to meet continuously changing global market and fulfill customer needs. This paper explores the relationships between different collaboration networks and technological innovation of small firms through an extensive review of literature. The study finds that collaboration with larger enterprises, R&D institutions, universities and government agencies play a significant role in enhancing technological innovation in small firms.

    Netter, Wendy J

    2003-01-01

    The Health Insurance Portability and Accountability Act has mandated the assignment of a universal individual health identifier in 2003. Such an identifier can increase patient confidentiality, improve patient care, lower the cost of services to the patient, enhance administrative efficiency, and increase the opportunity for medical research. Nevertheless, national identification systems raise concerns about confidentiality and privacy. Instead of a mandatory, government-assigned number, this article proposes a technologically multi-tiered system that would be administered by a mixed government and private entity. Consumers could voluntarily opt-in to the system.

    Full Text Available Learning ‘using’ technologies has become a global phenomenon. The Internet is often seen as a value-neutral tool that potentially allows individuals to overcome the constraints of traditional elitist spaces and gain unhindered access to learning. It is widely suggested that online technologies can help address issues of educational equity and social exclusion, and open up democratic and accessible educational opportunities. The national governments and non-governmental agencies who fund educational endeavours in developing countries have advocated the use of new technologies to reduce the cost of reaching and educating large numbers of children and adults who are currently missing out on education. This paper presents an overview of the educational developments in open, distance, and technology-facilitated learning that aim to reach the educationally deprived populations of the world. It reveals the challenges encountered by children and adults in developing countries as they attempt to access available educational opportunities. The discussion questions whether, in face of these challenges, developing nations should continue to invest money, time, and effort into e-learning developments. Can technology-enhanced learning help address the poverty, literacy, social, and political problems in developing countries?

  7. Sedation at sea of entangled North Atlantic right whales (Eubalaena glacialis to enhance disentanglement.

    Directory of Open Access Journals (Sweden)

    Michael Moore

    Full Text Available BACKGROUND: The objective of this study was to enhance removal of fishing gear from right whales (Eubalaena glacialis at sea that evade disentanglement boat approaches. Titrated intra muscular injections to achieve sedation were undertaken on two free swimming right whales. METHODOLOGY/PRINCIPAL FINDINGS: Following initial trials with beached whales, a sedation protocol was developed for right whales. Mass was estimated from sighting and necropsy data from comparable right whales. Midazolam (0.01 to 0.025 mg/kg was first given alone or with meperidine (0.17 to 0.25 mg/kg either once or four times over two hours to whale #1102 by cantilevered pole syringe. In the last attempt on whale #1102 there appeared to be a mild effect in 20-30 minutes, with duration of less than 2 hours that included exhalation before the blowhole fully cleared the water. Boat avoidance, used as a measure of sedation depth, was not reduced. A second severely entangled animal in 2009, whale #3311, received midazolam (0.03 mg/kg followed by butorphanol (0.03 mg/kg an hour later, delivered ballistically. Two months later it was then given midazolam (0.07 mg/kg and butorphanol (0.07 mg/kg simultaneously. The next day both drugs at 0.1 mg/kg were given as a mixture in two darts 10 minutes apart. The first attempt on whale #3311 showed increased swimming speed and boat avoidance was observed after a further 20 minutes. The second attempt on whale #3311 showed respiration increasing mildly in frequency and decreasing in strength. The third attempt on whale #3311 gave a statistically significant increase in respiratory frequency an hour after injection, with increased swimming speed and marked reduction of boat evasion that enabled decisive cuts to entangling gear. CONCLUSIONS/SIGNIFICANCE: We conclude that butorphanol and midazolam delivered ballistically in appropriate dosages and combinations may have merit in future refractory free swimming entangled right whale cases until

  8. Technology strategy for enhanced recovery; Technology Target Areas; TTA3 - enhanced recovery

    Energy Technology Data Exchange (ETDEWEB)

    2007-07-01

    The Norwegian Continental Shelf (NCS) is facing new challenges in reserve replacement and improved recovery in order to maintain the overall oil production rate from the area. A new target for an increase in oil reserves of 800 million Sm3 of oil (5 billion barrels) by year 2015 has been set by NPD. This is an ambitious goal considering several of the large fields are on a steep decline, and most of the recent discoveries are relatively small. A significant part of these increased reserves will have to come from fields currently on production, from reservoir areas that have been partly or fully swept, and it is therefore evident that Enhanced Oil Recovery (EOR) methods have to play a key role in achieving this target. EOR methods can be divided into gas based EOR methods and water based EOR methods. Thermal methods are not considered applicable on the NCS due to the relatively light oils present, and the depth of the reservoirs. Gas Based EOR; Water Based EOR; CO{sub 2} injection; Surfactants; Air injection; Polymer; Nitrogen injection; Alkaline; Flue gas injection; Polymer gels; WAG; MEOR; FAWAG. The former OG21 strategy document gave high priority to Water Alternating Gas (WAG) methods and CO{sub 2} injection for enhanced recovery. A lot of research and development and evaluation projects on CO{sub 2} injection were launched and are on-going, most of these are being CO{sub 2} WAG studies. The main challenge now in order to realize CO{sub 2} injection on the NCS is on CO{sub 2} availability and transport. It is also believed that increasing gas prices will limit the availability of hydrocarbon gas for injection purposes in the future. There is, however, a clear need for developing alternative cost efficient EOR methods that can improve the sweep efficiency significantly. Since a majority of the fields on the NCS are being produced under water flooding (or WAG), methods that can improve the water flooding efficiency by chemical additives are of special interest and

    In recent decades, a growing worldwide trend of developing the biodegradable lubricants has been prevailing to form a speciifc ifeld of green chemistry and green engineering. Enhancement of biodegradability of unreadily biodegradable petroleum-based lubricants has as such become an urgent must. For over a decade the authors have been focusing on the im-provement of biodegradability of unreadily biodegradable lubricants such as petroleum-based lubricating oils and greases. A new idea of lubricant biodegradation enhancer was put forward by the authors with the aim to stimulate the biodegradation of unreadily biodegradable lubricants by incorporating the enhancer into the lubricants in order to turn the lubricants into greener biodegradable ones and to help in situ bioremediation of lubricant-contaminated environment. This manuscript sum-marizes our recent efforts relating to the chemistry and technology of biodegradation enhancers for lubricants. Firstly, the chemistry of lubricant biodegradation enhancers was designed based on the principles of bioremediation for the treatment of hydrocarbon contaminated environment. Secondly, the ability of the designed biodegradation enhancers for increasing the biodegradability of unreadily biodegradable industrial lubricants was investigated through biodegradability evaluation tests, microbial population analysis, and biodegradation kinetics modeling. Finally, the impact of biodegradation enhancers on some crucial performance characteristics of lubricants such as lubricity and oxidation stability was tested via tribological evaluation and oxidation determinations. Our results have shown that the designed chemistry of nitrogenous and/or phos-phorous compounds such as lauroyl glutamine, oleoyl glycine, oleic diethanolamide phosphate and lauric diethanolamide borate was outstanding in boosting biodegradation of petroleum-based lubricants which was ascribed to increase the micro-bial population and decrease the oil-water interfacial

    Griffin, John W

    2013-03-01

    Though the treatment of diabetes has advanced remarkably, the law and many employers have not always kept pace. New insulins, delivery systems, and monitoring systems give people with diabetes exceptional control over their blood sugar and virtually eliminate serious complications such as hypoglycemia and hyperglycemia. Changes in the law, particularly the Americans with Disabilities Act and its 2008 amendments, give people with diabetes greater rights and employment opportunities than ever before. Despite these advances, many employers continue to use blanket bans or ill-considered standards to bar people with diabetes. Efforts to break down these remaining barriers are ongoing through employee litigation and through the American Diabetes Association's collaboration with entities that set occupational standards. © 2013 Diabetes Technology Society.

    2011-01-01

    This paper aims to systematically investigate the impacts of strengthening intellectual property rights on patenting in China's high-technology industries and to explore the potential differences in response to patent reform by ownership. Empirical results show that the estimated patent elasticity of R &D is lower than that for OECD countries, indicating relatively low R&D productivity for China's high-technology industries. The direct innovation effect of technology imports is negative, while the absorptive ability embodied in R&D helps in gaining external sources of knowledge, thus contributing to innovations. Specifically, strengthening intellectual property rights can induce more innovations in terms of patents in China's high-technology industries and is particularly relevant to foreign-owned high- technology enterprises.

    Marine mammals have recently been documented as important facilitators of rapid and efficient nutrient recycling in coastal and offshore waters. Whales enhance phytoplankton nutrition by releasing fecal plumes near the surface after feeding and by migrating from highly productive, high-latitude feeding areas to low-latitude nutrient-poor calving areas. In this study, we measured NH4+ and PO43- release rates from the feces of North Atlantic right whales (Eubalaena glacialis), a highly endangered baleen whale. Samples for this species were primarily collected by locating aggregations of whales in surface-active groups (SAGs), which typically consist of a central female surrounded by males competing for sexual activity. When freshly collected feces were incubated in seawater, high initial rates of N release were generally observed, which decreased to near zero within 24 hours of sampling, a pattern that is consistent with the active role of gut microflora on fecal particles. We estimate that at least 10% of particulate N in whale feces becomes available as NH4+ within 24 hours of defecation. Phosphorous was also abundant in fecal samples: initial release rates of PO43- were higher than for NH4+, yielding low N/P nutrient ratios over the course of our experiments. The rate of PO43- release was thus more than sufficient to preclude the possibility that nitrogenous nutrients supplied by whales would lead to phytoplankton production limited by P availability. Phytoplankton growth experiments indicated that NH4+ released from whale feces enhance productivity, as would be expected, with no evidence that fecal metabolites suppress growth. Although North Atlantic right whales are currently rare (approximately 450 individuals), they once numbered about 14,000 and likely played a substantial role in recycling nutrients in areas where they gathered to feed and mate. Even though the NH4+ released from fresh whale fecal material is a small fraction of total whale fecal nitrogen

    Chiu, Jennifer Lopseen

    Dynamic visualizations of scientific phenomena have the potential to transform how students learn and understand science. Dynamic visualizations enable interaction and experimentation with unobservable atomic-level phenomena. A series of studies clarify the conditions under which embedding dynamic visualizations in technology-enhanced inquiry instruction can help students develop robust and durable chemistry knowledge. Using the knowledge integration perspective, I designed Chemical Reactions, a technology-enhanced curriculum unit, with a partnership of teachers, educational researchers, and chemists. This unit guides students in an exploration of how energy and chemical reactions relate to climate change. It uses powerful dynamic visualizations to connect atomic level interactions to the accumulation of greenhouse gases. The series of studies were conducted in typical classrooms in eleven high schools across the country. This dissertation describes four studies that contribute to understanding of how visualizations can be used to transform chemistry learning. The efficacy study investigated the impact of the Chemical Reactions unit compared to traditional instruction using pre-, post- and delayed posttest assessments. The self-monitoring study used self-ratings in combination with embedded assessments to explore how explanation prompts help students learn from dynamic visualizations. The self-regulation study used log files of students' interactions with the learning environment to investigate how external feedback and explanation prompts influence students' exploration of dynamic visualizations. The explanation study compared specific and general explanation prompts to explore the processes by which explanations benefit learning with dynamic visualizations. These studies delineate the conditions under which dynamic visualizations embedded in inquiry instruction can enhance student outcomes. The studies reveal that visualizations can be deceptively clear

    Full Text Available Distance learning has provided an excellent platform for students in geographically remote locations while enabling them to learn at their own pace and convenience. A number of technologies are currently being utilized to conceptualize, design, enhance and foster distance learning. Teleconferences, electronic field trips, podcasts, webinars, video conferencing and online courses are among such technologies used in providing distance learning opportunities. However limitations in those existing technologies have affected to the increase of distance learners dropout rates. As an attempt to overcome the limitations in the currently adopted distance learning practices, the study aims to utilize 3D Hologram Technology (3DHT in the Engineering discipline. 3D hologram facilitates live and life size 3D telepresence that can interact with remote audiences. A survey had been conducted, using Delphi Technique to gather data from the experts in the field to evaluate the potential of 3DHT over existing technologies. Results of the survey suggested that 3DHT as a good distance learning technology and have the potential of overcoming existing limitations. Lack of infrastructure, High initial cost of infrastructure and Lack of technical know how are the main encounters identified by the experts in the sample. It is expected to develop a classroom environment with 3DHT and to evaluate its effectiveness for the distance learning in the next stage of the study.

    Electricity production from geothermal resources is currently based on the exploitation of hydrothermal reservoirs. Hydrothermal reservoirs possess three ingredients critical to present day commercial extraction of subsurface heat: high temperature, in-situ fluid and high permeability. Relative to the total subsurface heat resource available, hydrothermal resources are geographically and quantitatively limited. A 2006 DOE sponsored study led by MIT entitled 'The Future of Geothermal Energy' estimates the thermal resource underlying the United States at depths between 3 km and 10 km to be on the order of 14 million EJ. For comparison purposes, total U.S. energy consumption in 2005 was 100 EJ. The overwhelming majority of this resource is present in geological formations which lack either in-situ fluid, permeability or both. Economical extraction of the heat in non-hydrothermal situations is termed Enhanced or Engineered Geothermal Systems (EGS). The technologies and processes required for EGS are currently in a developmental stage. Accessing the vast thermal resource between 3 km and 10 km in particular requires a significant extension of current hydrothermal practice, where wells rarely reach 3 km in depth. This report provides an assessment of well construction technology for EGS with two primary objectives: (1) Determining the ability of existing technologies to develop EGS wells. (2) Identifying critical well construction research lines and development technologies that are likely to enhance prospects for EGS viability and improve overall economics. Towards these ends, a methodology is followed in which a case study is developed to systematically and quantitatively evaluate EGS well construction technology needs. A baseline EGS well specification is first formulated. The steps, tasks and tools involved in the construction of this prospective baseline EGS well are then explicitly defined by a geothermal drilling contractor in terms of sequence, time and

    During the last decades the global agricultural production has soared up and technology enhancement is still making positive contribution to yield growth. However, continuing population, water crisis, deforestation and climate change threaten the global food security. Attempts to predict food availability in the future around the world can be partly understood from the impact of changes to date. A new multilevel model for yield prediction at the country scale using climate covariates and technology trend is presented in this paper. The structural relationships between average yield and climate attributes as well as trends are estimated simultaneously. All countries are modeled in a single multilevel model with partial pooling and/or clustering to automatically group and reduce estimation uncertainties. El Niño Southern Oscillation (ENSO), Palmer Drought Severity Index (PDSI), Geopotential height (GPH), historical CO2 level and time-trend as a relatively reliable approximation of technology measurement are used as predictors to estimate annual agricultural crop yields for each country from 1961 to 2007. Results show that these indicators can explain the variability in historical crop yields for most of the countries and the model performs well under out-of-sample verifications.

    A new method for the ultrasonic enhancement of oil recovery from failing wells is described. The technology involves lowering a source of power ultrasound to the bottom of the well either for a short treatment before removal or as a permanent placement for intermittent use. In wells where the permeability is above 20 mD and the porosity is greater than 15% ultrasonic treatment can increase oil production by up to 50% and in some cases even more. For wells of lower permeability and porosity ultrasonic treatment alone is less successful but high production rates can be achieved when ultrasound is applied in conjunction with chemicals. An average productivity increase of nearly 3 fold can be achieved for this type of production well using the combined ultrasound with chemical treatment technology. Copyright © 2013 Elsevier B.V.

  2. Microgravity Boiling Enhancement Using Vibration-Based Fluidic Technologies

    Smith, Marc K.; Glezer, Ari; Heffington, Samuel N.

    2002-11-01

    Thermal management is an important subsystem in many devices and technologies used in a microgravity environment. The increased power requirements of new Space technologies and missions mean that the capacity and efficiency of thermal management systems must be improved. The current work addresses this need through the investigation and development of a direct liquid immersion heat transfer cell for microgravity applications. The device is based on boiling heat transfer enhanced by two fluidic technologies developed at Georgia Tech. The first of these fluidic technologies, called vibration-induced bubble ejection, is shown in Fig. 1. Here, an air bubble in water is held against a vibrating diaphragm by buoyancy. The vibrations at 440 Hz induce violent oscillations of the air/water interface that can result in small bubbles being ejected from the larger air bubble (Fig. 1a) and, simultaneously, the collapse of the air/water interface against the solid surface (Fig. 1b). Both effects would be useful during a heat transfer process. Bubble ejection would force vapor bubbles back into the cooler liquid so that they can condense. Interfacial collapse would tend to keep the hot surface wet thereby increasing liquid evaporation and heat transfer to the bulk liquid. Figure 2 shows the effect of vibrating the solid surface at 7.6 kHz. Here, small-scale capillary waves appear on the surface of the bubble near the attachment point on the solid surface (the grainy region). The vibration produces a net force on the bubble that pushes it away from the solid surface. As a result, the bubble detaches from the solid and is propelled into the bulk liquid. This force works against buoyancy and so it would be even more effective in a microgravity environment. The benefit of the force in a boiling process would be to push vapor bubbles off the solid surface, thus helping to keep the solid surface wet and increasing the heat transfer. The second fluidic technology to be employed in this

    In all recent missions our forces are faced with various types of asymmetric threads like snipers, IEDs, RPGs or MANPADS. 2 nd and 3 rd Gen IR technology is a backbone of modern force protection by providing situational awareness and accurate target engagement at day/night. 3 rd Gen sensors are developed for thread warning capabilities by use of spectral or spatial information. The progress on a dual-color IR module is discussed in a separate paper [1]. A 1024x256 SWIR array with flexure bearing compressor and pulse tube cold finger provides > 50,000h lifetime for space or airborne hyperspectral imaging in pushbroom geometry with 256 spectral channels for improved change detection and remote sensing of IEDs or chemical agents. Similar concepts are pursued in the LWIR with either spectroscopic imaging or a system of LWIR FPA combined with a cooled tunable Laser to do spectroscopy with stimulated absorption of specific wavelengths. AIM introduced the RangIR sight to match the requirements of sniper teams, AGLs and weapon stations, extending the outstanding optronic performance of the fielded HuntIR with position data of a target by a laser range finder (LRF), a 3 axis digital magnetic compass (DMC) and a ballistic computer for accurate engagement of remote targets. A version with flexure bearing cooler with >30,000h life time is being developed for continuous operation in e.g. gunfire detection systems. This paper gives an overview of AIM's technologies for enhanced force protection.

    Enhanced oil recovery (EOR) techniques can significantly extend global oil reserves once oil prices are high enough to make these techniques economic. Given a broad consensus that we have entered a period of supply constraints, operators can at last plan on the assumption that the oil price is likely to remain relatively high. This, coupled with the realization that new giant fields are becoming increasingly difficult to find, is creating the conditions for extensive deployment of EOR. This paper provides a comprehensive overview of the nature, status and prospects for EOR technologies. It explains why the average oil recovery factor worldwide is only between 20% and 40%, describes the factors that contribute to these low recoveries and indicates which of those factors EOR techniques can affect. The paper then summarizes the breadth of EOR processes, the history of their application and their current status. It introduces two new EOR technologies that are beginning to be deployed and which look set to enter mainstream application. Examples of existing EOR projects in the mature oil province of the North Sea are discussed. It concludes by summarizing the future opportunities for the development and deployment of EOR.

    Undesirably high concentrations of DDT and its daughter products DDE and DDD in some soils at Point Pelee National Park (PPNP) in Leamington, Ontario, Canada has resulted in restricted access to relatively large areas of the park. The contamination occurs primarily within the upper 20 cm thick Ah horizon, and has been linked to elevated levels within numerous local fauna. The common solution of "dig-and-dump" is not practical in this case since it would destroy the local protected ecosystem. Field trials conducted by McMaster University in partnership with Environment Canada, and Parks Canada have indicated that the application of solutions of cyclodextrin as a low-impact soil flushing/enhanced biodegradation remediation technology can remove a large proportion of DDT, DDE and DDD from the soil within a few months. Based upon previous studies at PPNP, the naturally occurring degradation processes would take decades to achieve the same mass loss. The cyclodextrin solutions exhibited a strong "tailing-effect" after approximately ten pore-volumes had passed through the Ah. There was an effect on soil hydraulic properties with decreased hydraulic conductivities and higher soil water retention, particularly where the higher concentration solutions were applied. The results indicate that soil flushing with cyclodextrin is highly effective to remediate pesticide contaminated soils. Additional work will quantify the relative amount of enhanced degradation versus mobilisation.

    The successful adoption of technology is becoming increasingly important to functional independence. The present article reports findings from the Center for Research and Education on Aging and Technology Enhancement (CREATE) on the use of technology among community-dwelling adults. The sample included 1,204 individuals ranging in age from 18-91 years. All participants completed a battery that included measures of demographic characteristics, self-rated health, experience with technology, attitudes toward computers, and component cognitive abilities. Findings indicate that the older adults were less likely than younger adults to use technology in general, computers, and the World Wide Web. The results also indicate that computer anxiety, fluid intelligence, and crystallized intelligence were important predictors of the use of technology. The relationship between age and adoption of technology was mediated by cognitive abilities, computer self-efficacy, and computer anxiety. These findings are discussed in terms of training strategies to promote technology adoption.

    Science.gov (United States)

    Marks, Stephen P

    2014-12-01

    The expansion of the corpus of international human rights to include the right to water and sanitation has implications both for the process of recognizing human rights and for future developments in the relationships between technology, engineering and human rights. Concerns with threats to human rights resulting from developments in science and technology were expressed in the early days of the United Nations (UN), along with the recognition of the ambitious human right of everyone "to enjoy the benefits of scientific progress and its applications." This comment explores the hypothesis that the emerging concepts most likely to follow recognition of the human right to water primarily involve issues of science and technology, such as access to medicines or clean and healthy environment. Many threats to human rights from advances in science, which were identified in the past as potential, have become real today, such as invasion of privacy from electronic recording, deprivation of health and livelihood as a result of climate change, or control over individual autonomy through advances in genetics and neuroscience. This comment concludes by urging greater engagement of scientists and engineers, in partnership with human rights specialists, in translating normative pronouncements into defining policy and planning interventions.

  9. Enabling Technology to Advance Health-Protecting Individual Rights-Are We Walking the Talk?

    Science.gov (United States)

    Sharp, Crystal; Gwadry-Sridhar, Femida

    The evolving structure and business of health care services and delivery need the functionality and capability offered by electronic health record (EHR) systems. By electronically diffusing the traditional patient record, however, this new model blurs the long-established medical data home, raising concerns about data ownership, confidentiality, access and individual rights. In 2008 the Lawson Health Research Institute began the process of instituting a robust health informatics and collaborative research infrastructure, now known as I-THINK Research. As data are migrated to the platform and policies are developed, we are forced to confront the complexity of issues around protection of individual rights. The paper presents, in a broader context, the main issues surrounding the privacy debate and the need for education, accountability and new legislation to help define and protect individual rights as new e-health business models emerge.

  7. Using Technology-Nested Instructional Strategies to Enhance Student Learning

    Directory of Open Access Journals (Sweden)

    Angela Lumpkin, PhD

    2015-08-01

    Full Text Available Students today expect the use of technology in their classes, rather than have to listen to less-than-engaging lectures. College students are connected electronically and incessant technology consumers. As a result, they may prefer the infusion of technologies to help them learn and enjoy the process of learning, rather than having to listen exclusively to lectures. To investigate this, the authors solicited student perceptions to assess the importance of learning through technology-nested instructional strategies. Student perceptions give direction to and affirm the benefits of instructional strategies that increase student motivation to engage more actively in their learning. Based on quantitative and qualitative responses through action research in multiple courses, students perceive their learning as more engaging and enjoyable when technology-nested instructional strategies are infused into their classes.

  12. The Right Way Through the Region of Sin: Islam, Bioethics and New Reproductive Technologies

    Directory of Open Access Journals (Sweden)

    Marko Pišev

    2016-02-01

    Full Text Available In the 1980s numerous debates were held in the House of Lords on the scientific research of embryos, with certain participants attempting to point out the difference between two styles of thought, namely, religious and scientific thought. Yet was the conflict in the House of Lords between two styles of thinking, or rather between the proponents of the scientific approach, on the one hand, and the proponents of religious thought, on the other, for intellectual and moral domination in society? Clearly, these debates hinted at something beyond and something more complex than a mere concern about embryos. What was actually being problematized? Or, to put it differently, to what extent does the use of bioreproductive technologies call into question the notions and issues of ethics, procreation and kinship, regardless of the religious dogma that considers the possibilities of their application? This paper will be confined to an analysis of Islamic dogma and any correspondences between this dogma and certain aspects of the new reproductive technologies. Still, in order to be able to discuss the relation between the new reproductive technologies and Islamic ethics, it is necessary to devote the greater part of this paper to an interpretation of how man is perceived in the context of the Koran.

    Among the earliest applications of health technologies to a safety program was the development of blood alcohol content (BAC) tests for use in impaired-driving enforcement. This led to the development of miniature, highly accurate devices that officers could carry in their pockets. A natural extension of this technology was the vehicle alcohol interlock, which is used to reduce recidivism among drivers convicted of driving under the influence (DUI) by requiring them to install the devices (which will not allow someone with a positive BAC to drive) on their vehicles. While on the vehicle, interlocks have been shown to reduce recidivism by two-thirds. Use of these devices has been growing at the rate of 10 to 15 percent a year, and there currently are more than 300,000 units in use. This expansion in the application of interlocks has benefited from the integration of other emerging technologies into interlock systems. Such technologies include data systems that record both driver actions and vehicle responses, miniature cameras and face recognition to identify the user, Wi-Fi systems to provide rapid reporting on offender performance and any attempt to circumvent the device, GPS tracking of the vehicle, and more rapid means for monitoring the integrity of the interlock system. This article describes how these health technologies are being applied in interlock programs and the outlook for new technologies and new court sanctioning programs that may influence the growth in the use of interlocks in the future.

  18. Climate regulation enhances the value of second generation biofuel technology

    Hertel, T. W.; Steinbuks, J.; Tyner, W.

    2014-12-01

    Commercial scale implementation of second generation (2G) biofuels has long been 'just over the horizon - perhaps a decade away'. However, with recent innovations, and higher oil prices, we appear to be on the verge of finally seeing commercial scale implementations of cellulosic to liquid fuel conversion technologies. Interest in this technology derives from many quarters. Environmentalists see this as a way of reducing our carbon footprint, however, absent a global market for carbon emissions, private firms will not factor this into their investment decisions. Those interested in poverty and nutrition see this as a channel for lessening the biofuels' impact on food prices. But what is 2G technology worth to society? How valuable are prospective improvements in this technology? And how are these valuations affected by future uncertainties, including climate regulation, climate change impacts, and energy prices? This paper addresses all of these questions. We employ FABLE, a dynamic optimization model for the world's land resources which characterizes the optimal long run path for protected natural lands, managed forests, crop and livestock land use, energy extraction and biofuels over the period 2005-2105. By running this model twice for each future state of the world - once with 2G biofuels technology available and once without - we measure the contribution of the technology to global welfare. Given the uncertainty in how these technologies are likely to evolve, we consider a range cost estimates - from optimistic to pessimistic. In addition to technological uncertainty, there is great uncertainty in the conditions characterizing our baseline for the 21st century. For each of the 2G technology scenarios, we therefore also consider a range of outcomes for key drivers of global land use, including: population, income, oil prices, climate change impacts and climate regulation. We find that the social valuation of 2G technologies depends critically on climate change

    The transition to a competitive electricity market will require a more careful approach to intersystem coordination - planning, operations and pricing - than policy makers have yet recognized. But there`s still time to get it right. States have scheduled the starting date for retail wheeling. The government has opened the grid. Politically correct regulatory agencies declare that nobody will escape stranded costs. Engineers still warn about the need to maintain system reliability. But free marketeers have a ready answer: {open_quotes}Don`t worry. The market will furnish the solutions.{close_quotes} The authors would argue otherwise. Not because a market could not provide solutions, but because whole sectors of the electricity supply market have-so far-been omitted from the market. Hurried deregulation on a piecemeal basis may create some local successes, but also lead to unanticipated failures in other parts of the system. A workably competitive market must value all the important aspects in the system, otherwise piecemeal incentives may invite failure. The savings and loan debacle, the privatization of an oligopolistic generating sector in the United Kingdom, and the liberalization of long-distance communications in Canada followed by the financial collapse of most new entrants within a year are notable examples of misguided public policies that neglected a systems overview and did not get it right the first time.

    Full Text Available Improving teaching and learning methodologies is not just a wish but rather strife for most educational institutions globally. To attain this, the Adelaide Tambo School of Nursing Science implemented a Technology-enhanced Problem-Based Learning methodology in the programme B Tech Occupational Nursing, in 2006. This is a two-year post-basic nursing program. The students are geographically dispersed and the curriculum design is the typically student-centred outcomes-based education. The research question posed by this paper is: How does technology-enhanced problem-based learning enhance student-centred learning, thinking skills, social skills and social space for learners? To answer the above question, a case study with both qualitative and quantitative data was utilised. The participants consisted of all students registered for the subject Occupational Health level 4. The sample group was chosen from willing participants from the Pretoria, eMalahleni and Polokwane learning sites, using the snowball method. This method was seen as appropriate due to the timing of the study. Data was collected using a questionnaire with both open and closed-ended questions. An analyses of the students‟ end of year examination was also done, including a comparison of performances by students on technology enhanced problem-based learning and those on problem-based learning only. The findings revealed that with Technology-enhanced Problem Based Learning (PBL, students‟ critical thinking, problem solving, and social skills improved and that social space was enhanced. This was supported by improved grades in students‟ on Technology-enhanced PBL as compared to those on PBL only.

    To appraise the application of accepted good practice guidance on public involvement in assistive technology research and to identify its impact on the research team, the public, device and trial design. Critical reflection and within-project evaluation were undertaken in a case study of the development of a functional electrical stimulation device. Individual and group interviews were undertaken with lay members of a 10 strong study user advisory group and also research team members. Public involvement was seen positively by research team members, who reported a positive impact on device and study designs. The public identified positive impact on confidence, skills, self-esteem, enjoyment, contribution to improving the care of others and opportunities for further involvement in research. A negative impact concerned the challenge of engaging the public in dissemination after the study end. The public were able to impact significantly on the design of an assistive technology device which was made more fit for purpose. Research team attitudes to public involvement were more positive after having witnessed its potential first hand. Within-project evaluation underpins this case study which presents a much needed detailed account of public involvement in assistive technology design research to add to the existing weak evidence base. The evidence base for impact of public involvement in rehabilitation technology design is in need of development. Public involvement in co-design of rehabilitation devices can lead to technologies that are fit for purpose. Rehabilitation researchers need to consider the merits of active public involvement in research.

    Full Text Available Investigations of microbial ecology and diversity have been greatly enhanced by the application of culture-independent techniques. One such approach, metagenomics, involves sample collections from soil, water, and other environments. Extracted nucleic acids from bulk environmental samples are sequenced and analyzed, which allows microbial interactions to be inferred on the basis of bioinformatics calculations. In most environments, microbial interactions occur predominately in surface-adherent, biofilm communities. In this review, we address metagenomics sampling and biofilm biology, and propose an experimental strategy whereby the resolving power of metagenomics can be enhanced by incorporating a biofilm-enrichment step during sample acquisition.

    The US EPA is promulgating a new MCL for arsenic based on epidemiology studies. The concern from the water industry is that the new MCL will be significantly lower than the current MCL of 50 {micro}g/L. The new MCL, some speculate may be as low as 2 {micro}g/L or less, is expected to have a significant impact on water utilities that depend on groundwater supply or use aquifer storage and recovery technology for potable water resources. A questionnaire sent to the participants at the Arsenic Workshop (May, 1993) sponsored by Association of California Water Agencies and the Metropolitan Water District of Southern California indicated that 66% of the 50 water agencies responded will not be in compliance if the new MCL is set at 5 AGIL. The issues concern most of the water utilities are compliance cost and treatment technologies. There are very few, if any, water utilities that are treating water with the objective of removing arsenic to levels less than 2 {micro}g/L. Some technologies such as reverse osmosis are capable of removing arsenic to a very low level, however, there is no data available due to the analytical limitation. All these information are critical to the development of treatment technologies and compliance cost.

    2013-01-01

    Construction knowledge can be communicated and reused among project managers and jobsite engineers to alleviate problems on a construction jobsite and reduce the time and cost of solving problems related to constructability. This paper proposes a new methodology for the sharing of construction knowledge by using Building Information Modeling (BIM) technology. The main characteristics of BIM include illustrating 3D CAD-based presentations and keeping information in a digital format and facilitation of easy updating and transfer of information in the BIM environment. Using the BIM technology, project managers and engineers can gain knowledge related to BIM and obtain feedback provided by jobsite engineers for future reference. This study addresses the application of knowledge sharing management using BIM technology and proposes a BIM-based Knowledge Sharing Management (BIMKSM) system for project managers and engineers. The BIMKSM system is then applied in a selected case study of a construction project in Taiwan to demonstrate the effectiveness of sharing knowledge in the BIM environment. The results demonstrate that the BIMKSM system can be used as a visual BIM-based knowledge sharing management platform by utilizing the BIM technology.

    Background Bullying is a critical public health problem and a screening tool for use in healthcare is needed. Focus groups are a common tool for generating qualitative data when developing an instrument and evidence suggests that technology-enhanced focus groups can be effective in simultaneously engaging participants from diverse settings. Aim To examine the use of technology-enhanced focus groups in generating an item pool to develop a youth-bullying screening tool. Discussion The authors explore methodological and ethical issues related to conducting technology-enhanced focus groups, drawing on their experience in developing a youth-bullying measure. They conducted qualitative focus groups with professionals from the front lines of bullying response and intervention. They describe the experience of conducting technology-enhanced focus group sessions, focusing on the methodological and ethical issues that researchers engaging in similar work may encounter. Challenges associated with this methodology include establishing rapport among participants, privacy concerns and limited non-verbal communication. Conclusion The use of technology-enhanced focus groups can be valuable in obtaining rich data from a wide variety of disciplines and contexts. Organising these focus groups was inexpensive and preferred by the study's participants. Implications for practice Researchers should consider using technology-enhanced focus groups to generate data to develop health-related measurement tools.

    Full Text Available Electronic virtual markets can serve as an alternative tool for collecting information that is spread among numerous experts. This is the principal market functionality from the operators’ point of view. On the other hand it is profits that are the main interest of the market participants. What they expect from the market is liquidity as high as possible and the opportunity for unrestricted trading. Both the operator and the electronic market participant can be considered consumers of this particular market with reference to the requirements for the accuracy of its outputs but also for the market liquidity. Both the above mentioned groups of consumers (the operators and the participants themselves expect protection of their specific consumer rights, i.e. securing the two above mentioned functionalities of the market. These functionalities of the electronic market are, however, influenced by many factors, among others by participants’ activity. The article deals with the motivation tools that may improve the quality of the prediction market. In the prediction electronic virtual market there may be situations in which the commonly used tools for increasing business activities described in the published literature are not significantly effective. For such situations we suggest a new type of motivation incentive consisting in penalizing the individual market participants whose funds are not placed in the market. The functionality of the proposed motivation incentive is presented on the example of the existing data gained from the electronic virtual prediction market which is actively operated.

    The workplace may be an ideal venue for engaging African American women in behavioral interventions for weight reduction. To examine the effectiveness of a culturally enhanced EatRight dietary intervention among a group of predominately African American women in a workplace setting. Crossover design study. Workplace. A total of 39 women volunteered for this study, of whom 27 completed it. The control period involved observation of participants for 22 weeks after receiving standard counseling on lifestyle methods to achieve a healthy weight; following the control period, participants crossed over to the 22-week intervention period. The intervention was culturally enhanced using feedback derived from formative assessment and delivered as 15 group sessions. The primary outcome measure was the difference in weight change between the control and intervention periods; changes in waist circumference and quality of life were secondary outcomes. Most participants were obese, with a mean baseline body mass index of 36 kg/m², weight of 97.9 kg, and waist circumference of 111 cm. Weight increased during the control period by 0.7 kg but decreased by 2.6 kg during the intervention (net difference = -3.4 kg, P culturally enhanced behavioral weight loss intervention in a predominately African American workplace setting. The workplace may be conducive for targeting African American women who are disproportionately affected by obesity.

  7. The Right Hemisphere Planum Temporale Supports Enhanced Visual Motion Detection Ability in Deaf People: Evidence from Cortical Thickness

    Directory of Open Access Journals (Sweden)

    Martha M. Shiell

    2016-01-01

    Full Text Available After sensory loss, the deprived cortex can reorganize to process information from the remaining modalities, a phenomenon known as cross-modal reorganization. In blind people this cross-modal processing supports compensatory behavioural enhancements in the nondeprived modalities. Deaf people also show some compensatory visual enhancements, but a direct relationship between these abilities and cross-modally reorganized auditory cortex has only been established in an animal model, the congenitally deaf cat, and not in humans. Using T1-weighted magnetic resonance imaging, we measured cortical thickness in the planum temporale, Heschl’s gyrus and sulcus, the middle temporal area MT+, and the calcarine sulcus, in early-deaf persons. We tested for a correlation between this measure and visual motion detection thresholds, a visual function where deaf people show enhancements as compared to hearing. We found that the cortical thickness of a region in the right hemisphere planum temporale, typically an auditory region, was greater in deaf individuals with better visual motion detection thresholds. This same region has previously been implicated in functional imaging studies as important for functional reorganization. The structure-behaviour correlation observed here demonstrates this area’s involvement in compensatory vision and indicates an anatomical correlate, increased cortical thickness, of cross-modal plasticity.

We hope that this results will contribute to establishing the effective nuclear knowledge diffusion program system.

  9. Enhancing the Transition Capability of Danish Biomass Technology By Applying a Futures Study Backcasting Methodology on the Biogas Sector.

    Directory of Open Access Journals (Sweden)

    Rikke Lybæk

    2013-04-01

    Full Text Available This paper discusses how the Danish biogas sector can achieve the political goals set outby the Danish government, in order to turn around the currently weak implementation ofthe technology. Biogas technology provides many environmental and energy relatedbenefits, but the transition capability of the technology has so far not been supported by astable policy pushing the sector in the right direction. The paper argues that a moreholistic and consistent support for the biogas sector must be developed, enhancing itsindependence from shifting Danish policy regimes. This could be achieved by applying abackcasting methodology in combination with future research activities which areidentified by means of energy chain analysis. The paper stresses that future Danish biogasresearch should be applied all along the sector’s energy chain, and not just in parts of it,looking at enhancement of the transition capability within ‘Resources’,‘Technology/Conversion’ and ‘Distribution/End-use’. The future research activities,proposed in this paper are interconnected and thought backwards with the goal ofcreating reachable aims for achieving the political targets set forth before the year 2020and 2050.

    Nozaki, Tomohiro

    2013-09-01

    Plasma catalysis is one of the innovative next generation green technologies that meet the needs for energy and materials conservation as well as environmental protection. Non-thermal plasma uniquely generates reactive species independently of reaction temperature, and these species are used to initiate chemical reactions at unexpectedly lower temperatures than normal thermochemical reactions. Non-thermal plasma thus broadens the operation window of existing chemical conversion processes, and ultimately allows modification of the process parameters to minimize energy and material consumption. We have been specifically focusing on dielectric barrier discharge (DBD) as one of the viable non-thermal plasma sources for practical fuel reforming. In the presentation, room temperature one-step conversion of methane to methanol and hydrogen using a miniaturized DBD reactor (microplasma reactor) is highlighted. The practical impact of plasma technology on existing C1-chemistry is introduced, and then unique characteristics of plasma fuel reforming such as non-equilibrium product distribution is discussed.

    Full Text Available The aim of this study was to identify and quantify the bioactive constituents in the methanol extracts of Coptis Rhizome prepared by ultrafining technology. The indicator compound was identified by spectroscopic method and its purity was determined by HPLC. Moreover, the crude extracts and indicator compound were examined for their ability to inhibit the growth of Rhizoctonia solani Kühn AG-4 on potato dextrose agar plates. The indicator compound is a potential candidate as a new plant derived pesticide to control Rhizoctonia damping-off in vegetable seedlings. In addition, the extracts of Coptis Rhizome prepared by ultrafining technology displayed higher contents of indicator compound; they not only improve their bioactivity but also reduce the amount of the pharmaceuticals required and, thereby, decrease the environmental degradation associated with the harvesting of the raw products.

  17. From STEM to STEAM: Strategies for Enhancing Engineering & Technology Education

    Directory of Open Access Journals (Sweden)

    Andy M. Connor

    2015-05-01

    Full Text Available This paper sets out to challenge the common pedagogies found in STEM (Science, Technology, Engineering and Mathematics education with a particular focus on engineering. The dominant engineering pedagogy remains “chalk and talk”; despite research evidence that demonstrates its ineffectiveness. Such pedagogical approaches do not embrace the possibilities provided by more student-centric approaches and more active learning. The paper argues that there is a potential confusion in engineering education around the role of active learning approaches, and that the adoption of these approaches may be limited as a result of this confusion, combined with a degree of disciplinary egocentrism. The paper presents examples of design, engineering and technology projects that demonstrate the effectiveness of adopting pedagogies and delivery methods more usually attributed to the liberal arts such as studio based learning. The paper concludes with some suggestions about how best to create a fertile environment from which inquiry based learning can emerge as well as a reflection on whether the only real limitation on cultivating such approaches is the disciplinary egocentrism of traditional engineering educators.

  18. Technology for enhancing chest auscultation in clinical simulation.

    Ward, Jeffrey J; Wattier, Bryan A

    2011-06-01

    The ability to use an acoustic stethoscope to detect lung and/or heart sounds, and then to then communicate one's interpretation of those sounds is an essential skill for many medical professionals. Interpretation of lung and heart sounds, in the context of history and other examination findings, often aids the differential diagnosis. Bedside assessment of changing auscultation findings may also guide treatment. Learning lung and heart auscultation skills typically involves listening to pre-recorded normal and adventitious sounds, often followed by laboratory instruction to guide stethoscope placement, and finally correlating the sounds with the associated pathophysiology and pathology. Recently, medical simulation has become an important tool for teaching prior to clinical practice, and for evaluating bedside auscultation skills. When simulating cardiovascular or pulmonary problems, high-quality lung and heart sounds should be able to accurately corroborate other findings such as vital signs, arterial blood gas values, or imaging. Digital audio technology, the Internet, and high-fidelity simulators have increased opportunities for educators and learners. We review the application of these technologies and describe options for reproducing lung and heart sounds, as well as their advantages and potential limitations.

    2014-09-01

    Full Text Available Although technology is successfully being used these days as a tool to improve education at all levels, its improper usage is curbing the imagination of the student community, leading to a diminution in their thinking capacity and ability to focus and concentrate. As attention is a vital cognitive feature of any learning process, students these days are not coping well with this process. This study attempts to analyse the focusing capacity of students from two different backgrounds; students who have undergone training in mental arithmetic and usage of the abacus and students without any formal mental arithmetic training. The analysis is done through a simple Electroencephalogram (EEG based gaming software, which measures the time needed for the players to focus and reach a specific attention level. An EEG device measures brain invoked potentials. Due to the availability of low cost commercial grade EEG devices, usage of these devices today, is not confined only to research and clinical purposes, but is being used beyond these applications. This study is an attempt to apply Brain Computer Interface (BCI Technology to assess cognition. The performance of the first category was found to be better than the second set of students.

    Emerging parasite resistance and poor oral bioavailability of anti-malarials are the two cardinal issues which hinder the clinical success of malaria chemotherapy. Atovaquone-Proguanil is a WHO approved fixed dose combination used to tackle the problem of emerging resistance. However, Atovaquone is a highly lipophilic drug having poor aqueous solubility (less than 0.2 μg/ml) thus reducing its oral bioavailability. The aim of the present investigation was to explore hot melt extrusion (HME) as a solvent-free technique to enhance solubility and oral bioavailability of Atovaquone and to develop an oral dosage form for Atovaquone-Proguanil combination. Solid dispersion of Atovaquone was successfully developed using HME. The solid dispersion was characterized for DSC, FTIR, XRD, SEM, and flow properties. It was filled in size 2 hard gelatin capsules. The formulation showed better release as compared to Malarone® tablets, and 3.2-fold and 4.6-fold higher bioavailability as compared to Malarone® tablets and Atovaquone respectively. The enhanced bioavailability also resulted in 100% anti-malarial activity in murine infection model at 1/8(th) therapeutic dose. Thus the developed methodology shows promising potential to solve the problems associated with Atovaquone therapy, namely its high cost and poor oral bioavailability, resulting in increased therapeutic efficacy of Atovaquone.

    Malignant ventricular arrhythmias resulting from isolated right ventricular myocardial infarction (RVMI) without left ventricular myocardial ischaemia or infarction occur rarely. We present a case of a 61 year-old male with acute onset of chest pain and ventricular fibrillation cardiac arrest requiring prompt defibrillation. Subsequent 15-lead EKG, showed ST-segment elevation in the anterior and right precordial leads without ST-segment elevation in the inferior leads. Angiography documented occlusion of a large RV marginal branch. Delayed enhancement cardiac magnetic resonance imaging (DE-CMR) with gadolinium performed two days post-infarct showed isolated RVMI. Patient remained symptom free and haemodynamically stable throughout his hospital stay. The clinical presentation of isolated RV infarct can be misleading and diagnosis difficult. EKG findings can resemble acute anterior wall myocardial infarction, while its course can be accompanied by life-threatening ventricular arrhythmias. This case uniquely combines this rare clinical sequence with DE-CMR images using gadolinium to confirm isolated RVMI. A brief review of RVMI presentation and associated EKG patterns is also discussed.

  3. Using Web 2.0 Technology to Enhance, Scaffold and Assess Problem-Based Learning

    2013-08-01

    Full Text Available Web 2.0 technologies, such as social networks, wikis, blogs, and virtual worlds provide a platform for collaborative working, facilitating sharing of resources and joint document production. They can act as a stimulus to promote active learning and provide an engaging and interactive environment for students, and as such align with the philosophy of Problem-based Learning. Furthermore, Web 2.0 technologies can provide the tutor or facilitator with an opportunity to scaffold and asses the PBL process. However, whilst it is recognised that technology has an important role in enhancing each step of a PBL exercise, academic staff can be reluctant to use it. This paper provides some illustrative examples of the technologies that have been used to enhance, scaffold and assess PBL and their evaluation by distance learning and on-campus students at the University of Ulster. The benefits and limitations of using technology for both staff and students to support PBL are discussed.

    As in acute care, use of health information technology in long-term care holds promise for increased efficiency, better accuracy, reduced costs, and improved outcomes. A comprehensive electronic health record (EHR), which encompasses all health care measures that clinicians want to use-both standard health care assessments and those acquired through emerging technology-is the key to improved, efficient clinical decision making. New technologies using sensors to passively monitor older adults at home are being developed and are commercially available. However, integrating the clinical information systems with passive monitoring data so that clinical decision making is enhanced and patient records are complete is challenging. Researchers at the University of Missouri (MU) are developing a comprehensive EHR to: (a) enhance nursing care coordination at TigerPlace, independent senior housing that helps residents age in place; (b) integrate clinical data and data from new technology; and (c) advance technology and clinical research.

    2017-07-01

    A human physical asymmetry is the near 90% clockwise occipitoparietal scalp hair-whorl direction in Europeans, an incidence that approximates the left lateralization of speech and right-handedness. Hair-whorl direction is also asymmetric in horses, Equus ferus caballus and placement is proposed to be related to temperament and lateralized skill in equitation manoeuvres. We describe a hair-whorl asymmetry in the horse, mane direction. Of 526, 3-year-old American Quarter horses, 69% of horses had mane directed to the right and 31% had mane directed to the left. The bias was larger in females, with 74% of females vs. 65% of males having mane directed to the right. Mane direction was unrelated to coat colour. The behavioural significance of mane asymmetry was investigated using judges' scores from a reining competition requiring symmetrical maneuvers of spin, circle and roll-back to either the left or to the right. There was no relation between mane asymmetry and overall reining performance and no relation between mane direction and scores for left or right manoeuvres. The results are discussed in relation to the significance of morphological asymmetries, neural function and the influence of planar cell polarity genes, such as Frizzled, that influence epidermal hair cell patterning.

    We are developing grazing-incidence x-ray optics for high-energy astrophysics using the electroform-nickel replication process. In this process, mirror shells are fabricated by replication off super-polished cylindrical mandrels. The mirrors fabricated using this process have a demonstrated optical performance at the level of 11-12 arc seconds resolution (HPD) for 30 keV x rays. Future missions demand ever higher angular resolutions and this places stringent requirements on the quality of the mandrels, the precision of the metrology, and the mounting and alignment of the mirror shells in their housings. A progress report on recent technology developments in all these areas will be presented along with a discussion on possible post fabrication, in-situ improvement of the x-ray mirrors quality.

    2008-04-01

    This paper describes a design for an innovative command and control system for an intelligent coastal maritime security system. The architecture for this intelligent coastal maritime security system is derived from the forth generation real-time control (RCS) system architecture1 developed by the National Institute of Science and Technology (NIST) over the past twenty years. This command and control system is a decision support system for real-time monitoring, response and training for security scenarios that can be hosted at various locations along the coast of the United States where homeland security surveillance and response activities are required. Additionally, this paper describes the design for a derivative real-time simulation based environment that can be used as a state-of-art test bed for developing new hardware and software components to be integrated into previous versions of deployed real-time control systems.

  9. Responsivity Enhanced NMOSFET Photodetector Fabricated by Standard CMOS Technology

    2015-01-01

    Full Text Available Increasing the responsivity is one of the important issues for a photodetector. In this paper, we demonstrate an improved NMOSFET photodetector by using deep-n-well (DNW structure which can improve the responsivity of the photodetector significantly. The experimental results show that the responsivity can be enhanced greatly by the DNW structure and is much larger than the previous work when DNW is biased with 0.5 V, while the dark current exhibits almost no increase. Further characterization indicates that the diode formed by the bulk and DNW can efficiently absorb photons and has a large gain factor of the photocurrent especially under low light condition, which gives a more promising application for the detector to detect the weak light.

  10. Enhanced Passive Cooling for Waterless-Power Production Technologies

    Recent advances in the literature and at SNL indicate the strong potential for passive, specialized surfaces to significantly enhance power production output. Our exploratory computational and experimental research indicates that fractal and swirl surfaces can help enable waterless-power production by increasing the amount of heat transfer and turbulence, when compared with conventional surfaces. Small modular reactors, advanced reactors, and non-nuclear plants (e.g., solar and coal) are ideally suited for sCO2 coolant loops. The sCO2 loop converts the thermal heat into electricity, while the specialized surfaces passively and securely reject the waste process heat in an environmentally benign manner. The resultant, integrated energy systems are highly suitable for small grids, rural areas, and arid regions.

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

    One of the greatest challenges for agricultural science in the 21st century is to improve yield stability through the progressive development of superior cultivars. The increasing numbers of infectious plant diseases that are caused by plant-pathogens make it ever more necessary to develop new strategies for plant disease resistance breeding. Targeted genome engineering allows the introduction of precise modifications directly into a commercial variety, offering a viable alternative to traditional breeding methods. Genome editing is a powerful tool for modifying crucial players in the plant immunity system. In this work, we propose and discuss genome-editing strategies and targets for improving resistance to phytopathogens. First of all, we present the opportunities to rewrite the effector-target sequence for avoiding effector-target molecular interaction and also to modify effector-target promoters for increasing the expression of target genes involved in the resistance process. In addition, we describe potential approaches for obtaining synthetic R-genes through genome-editing technologies (GETs). Finally, we illustrate a genome editing flowchart to modify the pathogen recognition sites and engineer an R-gene that mounts resistance to some phylogenetically divergent pathogens. GETs potentially mark the beginning of a new era, in which synthetic biology affords a basis for obtaining a reinforced plant defense system. Nowadays it is conceivable that by modulating the function of the major plant immunity players, we will be able to improve crop performance for a sustainable agriculture. PMID:27990151

    The Sterile Insect Technique (SIT) has been used very successfully against range of pest insects, including various tephritid fruit flies, several moths and a small number of livestock pests. However, modern genetics could potentially provide several improvements that would increase the cost-effectiveness of SIT, and extend the range of suitable species. These include improved identification of released individuals by incorporation of a stable, heritable, genetic marker; built-in sex separation (genetic sexing); reduction of the hazard posed by non-irradiated accidental releases from mass-rearing facility (fail-safe); elimination of the need for sterilization by irradiation (genetic sterilization). We discuss applications of these methods and the state of the art, at the time of this meeting, in developing suitable strains. We have demonstrated, in several key pest species, that the required strains can be constructed by introducing a repressible dominant lethal genetic system, a method known as RIDL(trade mark). Based on field experience with Medfly, incorporation of a genetic sexing system into SIT programs for other tephritids could potentially provide a very significant improvement in cost-effectiveness. We have now been able to make efficient female-lethal strains for Medfly. One advantage of our approach is that it should be possible rapidly to extend this technology to other fruit fly species; indeed we have recently been able also to make genetic sexing strains of Medfly (Anastrepha ludens).

    Full Text Available Human vision and memory are powerful cognitive faculties by which we understand the world. However, they are imperfect and further, subject to deterioration with age. We propose a cognitive-inspired computational model, Extended Visual Memory (EVM, within the Computer-Aided Vision (CAV framework, to assist human in vision-related tasks. We exploit wearable sensors such as cameras, GPS and ambient computing facilities to complement a user's vision and memory functions by answering four types of queries central to visual activities, namely, Retrieval, Understanding, Navigation and Search. Learning of EVM relies on both frequency-based and attention-driven mechanisms to store view-based visual fragments (VF, which are abstracted into high-level visual schemas (VS, both in the visual long-term memory. During inference, the visual short-term memory plays a key role in visual similarity computation between input (or its schematic representation and VF, exemplified from VS when necessary. We present an assisted living scenario, termed EViMAL (Extended Visual Memory for Assisted Living, targeted at mild dementia patients to provide novel functions such as hazard-warning, visual reminder, object look-up and event review. We envisage EVM having the potential benefits in alleviating memory loss, improving recall precision and enhancing memory capacity through external support.

  17. A technology enhanced course for communication incorporating empathy

    2013-09-01

    Full Text Available This paper aims at the dissemination of a new course design, which reports and shares our experience of designing a new course to meet the new needs in the society. The higher education has been focusing on developing students’ logical thinking or reasoning skills through debate, believing that such skills would make the students succeed in the society after graduation. However, from the view point of resilience in the society after a natural disaster, which usually demolishes the fundamental infrastructure as well as human bonding through trust, the communication with empathy to build trust seems to play a more important role than the skill to debate. Is there any way to incorporate such advanced communication skill with empathy in the higher education responding to the current needs from the society before the students become members of the society? Kansai University has developed a new experimental course for advanced communication with empathy to be implemented in the general education enhanced with ICT. This paper reports Kansai University’s successful problem-solving process and endeavor in the curriculum development for the communication with empathy.

    Palliative care services for patients with life-limiting conditions enhance their quality of life. Most palliative care services, however, are located in hospitals with limited transitional care for patients who live in distant locations. The long-term goal of this program of research is to use existing technology for virtual visits to provide transitional care for patients initially hospitalized in an urban setting by a nurse practitioner located closer to patients' homes in distant, rural settings. The purpose of this proof-of-concept study was to determine the resources needed to use the system (efficiency) and the quality of the audio and visual components (effectiveness) to conduct virtual visits between a clinician at an academic center and community-dwelling adults living in rural locations. Guided by the Technology Acceptance Model, a mixed-methods field design was used. Because of the burden of testing technology with patients with life-limiting conditions, the sample included eight healthy adults. Participant satisfaction and perceptions of the ease of using the technology were also measured. Virtual visits were conducted using a 3G-enabled Apple iPad, cellular phone data service, and a Web-based video conference service. Participants and clinicians perceived the technology as easy to use. Observations revealed the importance of the visual cues provided by the technology to enhance communication, engagement, and satisfaction. Findings from this study will inform a subsequent study of technology-enhanced transitional care with palliative care patients.

    2009-09-01

    The focus of this study includes the investigation of sampling technologies used in industry and their potential application to nuclear fuel processing. The goal is to identify innovative sampling methods using state of the art techniques that could evolve into the next generation sampling and analysis system for metallic elements. Sampling and analysis of nuclear fuel recycling plant processes is required both to monitor the operations and ensure Safeguards and Security goals are met. In addition, environmental regulations lead to additional samples and analysis to meet licensing requirements. The volume of samples taken by conventional means, can restrain productivity while results samples are analyzed, require process holding tanks that are sized to meet analytical issues rather than process issues (and that create a larger facility footprint), or, in some cases, simply overwhelm analytical laboratory capabilities. These issues only grow when process flowsheets propose new separations systems and new byproduct material for transmutation purposes. Novel means of streamlining both sampling and analysis are being evaluated to increase the efficiency while meeting all requirements for information. This report addresses just a part of the effort to develop and study novel methods by focusing on the sampling and analysis of aqueous samples for metallic elements. It presents an overview of the sampling requirements, including frequency, sensitivity, accuracy, and programmatic drivers, to demonstrate the magnitude of the task. The sampling and analysis system needed for metallic element measurements is then discussed, and novel options being applied to other industrial analytical needs are presented. Inductively coupled mass spectrometry instruments are the most versatile for metallic element analyses and are thus chosen as the focus for the study. Candidate novel means of process sampling, as well as modifications that are necessary to couple such instruments to

    2016-06-01

    This study assessed physicians' receptivity to using mobile technology as a strategy in patient care for adolescents with asthma. Understanding physicians' perceived barriers and benefits of integrating mobile technology in adolescents' asthma care and self-management is an initial step in enhancing overall patient and disease outcomes. We conducted in-depth interviews with second- and third-year pediatric residents and attending physicians who oversee pediatric residents in training (N = 27) at an academic medical center in the southeastern United States. We identified both benefits from and barriers to broader use of mobile technologies for improving asthma outcomes in adolescents. Resident physicians demonstrated greater readiness for integrating these technologies than did attending physicians. Prior to adoption of mobile technologies in the care of adolescent asthma patients, barriers to implementation should be understood. Prior to widespread adoption, such systems will need to be evaluated against traditional care for demonstration of patient outcomes that improve on the current situation.

Data were collected through interview schedule using questionnaires. Descriptive statistics and regression model were adopted to analyze data. Results show that adoption of quality enhancing technologies was low among the selected sample of these rice value chain actors. The adoption indices of on-farm and post-harvest quality enhancing practices were 0.46 and 0.37 respectively. Some socioeconomic attributes including: Age, level of education, contact with extension, access to credit and level of commercialization were statistically significant determining factors (P≤0.05 influencing adoption at farm level, while post-harvest technology adoption was determined by level of education, access to credit and membership of cooperatives. Promotion of quality enhanced technologies among these actors in the rice value chain is recommended.

    2013-05-01

    The aim of nursing education is to prepare students with critical thinking, high interests in profession and high proficiency in patient care. Cooperative learning promotes team work and encourages knowledge building upon discussion. It has been viewed as one of the most powerful learning methods. Technology has been considered an influential tool in teaching and learning. It assists students in gathering more information to solve the problems and master skills better. The purpose of this study was to compare the effect of technology-based cooperative learning with technology-based individual learning in nursing students' critical thinking in catheterization knowledge gaining, error discovering, skill acquisitions, and overall scores. This study used a pretest-posttest experimental design. Ninety-eight students were assigned randomly to one of two groups. Questionnaires and tests were collected at baseline and after completion of intervention. The results of this study showed that there was no significant difference in related catheterization skill performance. However, the remaining variables differed greatly between the two groups. CONCLUSIONS AND APPLICATIONS: This study's findings guide the researchers and instructors to use technology-based cooperative learning more appropriately. Future research should address the design of the course module and the availability of mobile devices to reach student-centered and learn on the move goals. Copyright © 2011 Elsevier Ltd.

    Full Text Available This short essay explores how the notion of hacktivism changes due to easily accessible, military grade Privacy Enhancing Technologies (PETs. Privacy Enhancing Technologies, technological tools which provide anonymous communications and protect users from online surveillance enable new forms of online political activism. Through the short summary of the ad-hoc vigilante group Anonymous, this article describes hacktivism 1.0 as electronic civil disobedience conducted by outsiders. Through the analysis of Wikileaks, the anonymous whistleblowing website, it describes how strong PETs enable the development of hacktivism 2.0, where the source of threat is shifted from outsiders to insiders. Insiders have access to documents with which power can be exposed, and who, by using PETs, can anonymously engage in political action. We also describe the emergence of a third generation of hacktivists who use PETs to disengage and create their own autonomous spaces rather than to engage with power through anonymous whistleblowing.

    Program evaluation has become increasingly important, and information on program performance often drives funding decisions. Technology use and integration can help ease the burdens associated with program evaluation by reducing the resources needed (e.g., time, money, staff) and increasing evaluation efficiency. This paper reviews how program evaluators, across disciplines, can apply internet and mobile technologies to key aspects of program evaluation, which consist of participant registration, participant tracking and retention, process evaluation (e.g., fidelity, assignment completion), and outcome evaluation (e.g., behavior change, knowledge gain). In addition, the paper focuses on the ease of use, relative cost, and fit with populations. An examination on how these tools can be integrated to enhance data collection and program evaluation is discussed. Important limitations of and considerations for technology integration, including the level of technical skill, cost needed to integrate various technologies, data management strategies, and ethical considerations, are highlighted. Lastly, a case study of technology use in an evaluation conducted by the Clearinghouse for Military Family Readiness at Penn State is presented and illustrates how technology integration can enhance program evaluation.

    Our aim was to examine the association between the extent of late gadolinium enhancement (LGE) at right ventricular insertion points (RVIP) and left ventricular (LV) functional parameters in patients with hypertrophic cardiomyopathy (HCM). Sixty-one HCM patients underwent echocardiography and cardiovascular magnetic resonance (CMR) within one week. Mitral annular velocities (E/E') were obtained from echocardiography; LV ejection fraction (EF), LV mass index, LV wall maximal thickness, and left atrial volume index (LAVI) were obtained from MR. LGE extent was quantified (proportion of total LV myocardial mass) according to location: % RVIP-LGE and % non-RVIP-LGE. Although LGE was commonly present in both apical (74 %) and non-apical HCMs (88 %) (p = 0.163), RVIP-LGE was more frequent (86 % vs. 47 %, p = 0.002) in non-apical HCMs in which E/E' was significantly higher (19.23 ± 8.40 vs. 13.13 ± 5.06, p = 0.009). In addition, RVIP-LGE extent was associated with LV diastolic dysfunction (r = 0.45, p < 0.001 for E/E'; r = 0.53, p < 0.001 for LAVI) and lower LVEF (r = -0.42, p = 0.001). There was no correlation between non-RVIP-LGE extent and other parameters. Multiple linear regression analysis revealed RVIP-LGE extent as an independent predictor of E/E' (β = 0.45, p < 0.001) and LAVI in HCM patients (β = 0.53, p < 0.001). The extent of LGE at RVIPs in HCM patients is associated with increased estimated LV filling pressure and chronic diastolic burden. (orig.)

    The article describes a five-year period of Technology Enhanced Learning (TEL) implementation at the Faculty of Materials Science and Technology (MTF) in Trnava. It is a part of the challenges put forward by the 7th Framework Programme (ICT research in FP7) focused on "how information and communication technologies can be used to support learning and teaching". The empirical research during the years 2006-2008 was focused on technology-driven support of teaching, i. e. the development of VLE (Virtual Learning Environment) and the development of database applications such as instruments developed simultaneously with the information support of the project, and tested and applied directly in the teaching of bachelor students. During this period, the MTF also participated in the administration of the FP7 KEPLER project proposal in the international consortium of 20 participants. In the following period of 2009-2010, the concept of educational activities automation systematically began to develop. Within this concept, the idea originated to develop a universal multi-purpose system BIKE based on the batch processing knowledge paradigm. This allowed to focus more on educational approach, i.e. TEL educational-driven and to finish the programming of the Internet application - network for feedback (communication between teachers and students). Thanks to this specialization, the results of applications in the teaching at MTF could gradually be presented at the international conferences focused on computer-enhanced engineering education. TEL was implemented at a detached workplace and four institutes involving more than 600 students-bachelors and teachers of technical subjects. Four study programmes were supported, including technical English language. Altogether, the results have been presented via 16 articles in five countries, including the EU level (IGIP-SEFI).

    Full Text Available Abstract Background Technology-enhanced learning (TEL gives a view to improved education. However, there is a need to clarify how TEL can be used effectively. The study compared students' attitudes and opinions towards a traditional face-to-face course on theoretical radiological science and a TEL course where students could combine face-to-face lectures and e-learning modules at their best convenience. Methods 42 third-year dental students were randomly assigned to the traditional face-to-face group and the TEL group. Both groups completed questionnaires before the beginning and after completion of the course on attitudes and opinions towards a traditional face-to-face lectures and technology-enhanced learning. After completion of the course both groups also filled in the validated German-language TRIL (Trierer Inventar zur Lehrevaluation questionnaire for the evaluation of courses given at universities. Results Both groups had a positive attitude towards e-learning that did not change over time. The TEL group attended significantly less face-to-face lectures than the traditional group. However, both groups stated that face-to-face lectures were the basis for education in a theoretical radiological science course. The members of the TEL group rated e-mail reminders significantly more important when they filled in the questionnaire on attitudes and opinions towards a traditional face-to-face lectures and technology-enhanced learning for the second time after completion of the course. The members of the technology-enhanced learning group were significantly less confident in passing the exam compared to the members of the traditional group. However, examination results did not differ significantly for traditional and the TEL group. Conclusions It seems that technology-enhanced learning in a theoretical radiological science course has the potential to reduce the need for face-to-face lectures. At the same time examination results are not impaired

The results show that the enhancement of intellectual property rights protection obviously promotes technology innovation; there is a complementary relationship be- tween intellectual property rights protection and R~D physical capital input and a substitutive relationship between intellectual property rights protection and R~D human capital input; the levels of intellectual property rights pro- tection in most of China have exceeded the threshold value and the enhance- ment of intellectual property rights protection cannot obstruct technology in- novation. Therefore, China should enhance intellectual property rights protection to improve its indigenous innovation capacity.%文章利用1997—2008年省级面板数据,以技术市场成交额占当地GDP的比重来衡量地区知识产权保护水平,采用系统广义矩估计和门槛回归方法实证分析了知识产权保护对技术创新的影响。研究结果表明,加强知识产权保护能够显著促进技术创新;知识产权保护与研发物质资本和人力资本投入之间分别具有互补性和替代性;我国大部分地区已经跨越了知识产权保护水平的门槛值,加强知识产权保护不会阻碍技术创新。因此,要提高我国的自主创新能力,进一步加强知识产权保护不容懈怠。

    A debated question in the literature is the degree of anatomical and functional lateralization of the executive control processes sub-served by the dorsolateral prefrontal cortex (DLPFC) during recognition memory retrieval. We investigated if transient inhibition and excitation of the left and right DLPFC at retrieval by means of repetitive transcranial magnetic stimulation (rTMS) modulate recognition memory performance in 100 healthy controls (HCs) and in eight patients with Mild Cognitive Impairment (MCI). Recognition memory tasks of faces, buildings, and words were used in different experiments. rTMS-inhibition of the right DLPFC enhanced recognition memory in both HCs and MCIs. rTMS-excitation of the same region in HCs deteriorated memory performance. Inhibition of the right DLPFC could modulate the excitability of a network of brain regions, in the ipsilateral as well as in the contralateral hemisphere, enhancing function in HCs or restoring an adaptive equilibrium in MCI.

    2016-01-01

    Full Text Available Author's rights and copyright law have gone through quite a few changes in the 'post-print' culture of binary systems, digital formations and techno-practices. Technological development supports new concept of author's rights by promoting free internet and digital market, as well as new contemporary experience of culture that is being rooted in digital technology, mass communication and the world of multimedia and virtuality. Though computer and digital technology have served both authors and users in various ways, they have also served as a very fertile ground for sharing copyrighted content thus leading to numerous copyright infringements and conflicts with the copyright law. The aim of this paper is to identify and analyze the ways in which computer and digital technology have given rise to new trends in the production (e.g. remix culture and consumption (e.g. peer-to-peer file sharing technology of culture, but also to determine how new forms of distribution, use and sharing of digital content changed and shaped the perception of authorship in the 21st century. In order to analyze the dynamic, nature and structure by which new digital and networking technologies are affecting the concept of authorship and author's rights and to test the consistency of previously established hypotheses, we conducted a survey amongst general public. Altogether 535 questionnaires were completed. Data was analyzed using SPSS tool and quantitative method of analysis. In the analysis special attention was given to both, the concept of authorship in the digital environment and the concept of peer-to-peer file sharing technology as not so new, but still very popular networked architecture for distributing, using and sharing digital content. Results have shown that most of the respondents use peer-to-peer file sharing technology to access, consume and/or share different cultural content (e.g. movies, music, books, etc. while violating the rights of copyright holders

The purpose of the study is to examine Turkish and American students’ attitudes and thoughts toward the use of educational technologies in history courses, and to compare the results to determine whether there are any differences between the attitudes of Turkish and American student. This study was conducted with 197 American students from Upper Saint Claire High school in Pittsburgh, PA, and 214 Turkish students from Konya High school who volutered for this study. The required data for this study were gathered by a 26-item technology questionnaire, which included 7 multiple-choice questions and 19 Likert scale questions. This questionnaire was developed to gather data on five different areas of interest: (1 demographic information, (2 participants’ computer- and Internet-usage skills, (3 the level of technology used in history classrooms, (4 participants’ attitudes toward technology-enhanced history education, and (5 participants’ attitudes toward history. Most of the Turkish and American students rated themselves as being very well experienced on the eight computer- and Internet-usage skills targeted in this study. But the comparison of the data indicated that American students have higher computer- and Internet-usage skills than Turkish students do, and this difference is statistically significant (p = 0.001. Most of the Turkish and American students showed positive attitudes on using educational technologies in history classrooms. A majority of the Turkish and American students stated that they would be able to focus and learn better if more technological materials were used in classroom activities, and this, in turn, would increase their academic achievements.

    Globally, the demand for safe, healthy and nutritious meat and allied products possesses improved taste with extended shelf life is mounting. Microbial safety is among the imperative challenges that prevails in meat products because they provide an ideal medium for the growth of microorganisms particularly pathogenic bacteria. The incidence of these microbes can result quality deterioration of products leading towards food borne diseases when consumed by peoples. Several preservation technologies like chemical and biological interventions are effective to retard or inactivate the growth of micro-organisms most commonly related to food-borne diseases. Despite these, innovative approaches like hydrostatic pressure processing, active packaging, pulse electric field, hurdle approach and use of natural antimicrobials can be deployed to enhance the safety of meat and meat products. The objective of review is to describe the current approaches and developing technologies for enhancing safety of meat and allied meat products.

    NASA Langley Research Center and the FAA collaborated in an effort to evaluate the effect of Enhanced Vision (EV) technology display in a commercial flight deck during low visibility surface operations. Surface operations were simulated at the Memphis, TN (FAA identifier: KMEM) air field during nighttime with 500 Runway Visual Range (RVR) in a high-fidelity, full-motion simulator. Ten commercial airline flight crews evaluated the efficacy of various EV display locations and parallax and mini cation effects. The research paper discusses qualitative and quantitative results of the simulation experiment, including the effect of EV display placement on visual attention, as measured by the use of non-obtrusive oculometry and pilot mental workload. The results demonstrated the potential of EV technology to enhance situation awareness which is dependent on the ease of access and location of the displays. Implications and future directions are discussed.

  6. Enhancing verbal creativity: modulating creativity by altering the balance between right and left inferior frontal gyrus with tDCS.

    2015-04-16

    Creativity is the production of novel ideas that have value. Previous research indicated that while regions in the right hemisphere are implicated in the production of new ideas, damage to the left inferior frontal gyrus (IFG) is associated with increased creativity, indicating that the left IFG damage may have a "releasing" effect on creativity. To examine this, in the present study we used transcranial direct current stimulation (tDCS) to modulate activity of the right and the left IFG. In the first experiment we show that whereas anodal tDCS over the right IFG coupled with cathodal tDCS over the left IFG increases creativity as measured by a verbal divergent thinking task, the reverse stimulation does not affect creative production. To further confirm that only altering the balance between the two hemispheres is crucial in modulating creativity, in the second experiment we show that stimulation targeting separately the left IFG (cathodal stimulation) or the right IFG (anodal stimulation) did not result in changes in creativity as measured by verbal divergent thinking. These findings support the balance hypothesis, according to which verbal creativity requires a balance of activation between the right and the left frontal lobes, and more specifically, between the right and the left IFG.

    Arbuscular mycorrhizal fungi (AMF) favored the accumulation of secondary metabolites in leaves of lettuces in previous studies. When fertilized with selenium (Se), mycorrhizal lettuces had more proteins, sugars and minerals than non-mycorrhizal ones. However, Se contents were lower in mycorrhizal plants suggesting a negative correlation between Se and AMF applications. The aim of the present study was to test if Se fertilization interfered with AMF technology for enhancing secondary metabolit...

  12. Heating Unsaturated Sediments Using Solar Energy to Enhance Passive Sediment Remediation Technologies

    Rossman, A.

    2002-12-01

    Sediment heating has been shown to enhance passive sediment remediation technologies such as bioremediation and barometric pumping (passive soil venting). Sediment heating raises the slow remediation rates that often limit the widespread use of these technologies. In bioremediation applications, a 10 degree C increase in subsurface temperature is expected to double the microbial activity, and thus the remediation rate. The removal rate of tetracholorethylene (PCE - a common subsurface contaminant) by passive soil vapor extraction is expected to nearly double in low-permeable sediments when the subsurface is heated 10 degree C from ambient temperatures due to an increased vapor pressure in the PCE. When the sediment is heated using renewable energy sources, these thermally enhanced remediation technologies can be environmentally benign alternatives to conventional remediation techniques that rely on large external energy inputs. The thermally enhanced passive technologies may be particularly useful for remediating unsaturated, low-permeable lenses that are troublesome to most conventional remediation technologies such as conventional soil vapor extraction and co-solvent flushes. The main objective of this work was to quantify subsurface sediment heating using a solar powered heat injection well. To do this, a pilot sediment heating system was installed in Vermont and high resolution meteorological and sediment temperature data were collected using a stand-alone data acquisition system. Unsaturated, silty sediments were heated in-situ by converting the direct and indirect solar energy available at the surface to heat energy in the subsurface using stand-alone renewable energy sources and a resistive element heat injection well. The heat injection well was powered by a 600-W passively tracking photovoltaic (PV) array and a small 1.2-m swept area wind turbine. It is envisioned that the heat injection well would be placed directly into an area of high subsurface

    2016-03-01

    Full Text Available This paper aims to investigate the effectiveness of the provision of privacy of individuals through privacy enhancing technologies (PETs. The successful evolution and emergence of cyberspace with the real world through “Internet of Everything (IoE” has led to the speedy progress in research and development of predictive analysis of big data. The individual’s privacy has gained a considerable momentum in both industry and academia since privacy-enhancing technologies (PETs constitute a technical means to protect information. Privacy regulations and state of law deemed this as an integral part in order to protect the individual’s private sphere when the infrastructure of Information Communication Technologies (ICT is laid out. Modern organisations use consent forms to gather individual’s sensitive personal information for a specific purpose. The law prohibits using the person’s information for purposes other than that of when the consent was initially established. The infrastructure of ICT should be developed in alliance with the privacy laws and made compliant as well intelligent which learn by itself from the environment. This extra layer embedded in the system would educate the ICT structure and help system to authenticate as well as communicate with the perspective users. The existing literature on protecting individuals’ privacy through privacy-enhancing technologies (PETs is still embryonic and does conclude that the individual’s concerns about privacy are not fully considered in the technological sense. Among other contributions, this research paper will devise a conceptual model to improve individual’s privacy.

    2017-03-01

    Full Text Available This study provides insight into technology-enhanced assessment (TEA in diverse higher education contexts. The effectiveness of using technology for assessment in higher education is still equivocal, particularly in regard to evidence of improvements in student learning. This empirical research explores the affordances that technology offers to assessment for transforming student learning. A systematic literature review, guided by an analytic survey tool, was used to identify and interrogate recent scholarly articles published in 19 international journals. From a total of 1713 articles, 139 articles were identified as being focused on the use of technology for assessment. The analytic tool guided the rigorous exploration of the literature regarding the types of technology being used, the educational goal, the type of assessment, and the degree of “transformation” afforded by the technology. Results showed that, in the sample investigated, TEA is used most frequently for formative peer learning, as part of the task design and feedback stages of the assessment cycle, and that social media has been a major affordance for this. Results are discussed with a view to fostering a future culture of inquiry and scholarship around TEA in higher education.

    2013-01-01

    Full Text Available The online course offerings have grown exponentially globally since the turn of the 21st century - be they as a primary mode of instruction or as a supplement to traditional face-to-face classroom instruction, and this phenomenon is most noticeable in higher education. More recently, the new technology has also been integrated into the English as a Foreign Language,henceforth called EFL, classrooms. This article argues that the notion of technology-enhanced language learning is not just an intriguing idea – it is a necessity, for it has a great potential to offer in facilitating the development of English language proficiency of EFL learners through computer-mediated communication. Additionally, it contends that the new technology can potentially address most, if not all, of the shortcomings inherent to the EFL classroom including, but not limited to, lack of exposure to the target language, lack of practice, and lack of learning resources. Theoretical implications of technology-enhanced language teaching and learning will also be explored.

    Current treatments for congenital coronary artery fistulas (CAFs) include surgical obliteration and transcatheter occlusion. However, surgical techniques involve significant trauma. Transcatheter occlusion is performed under fluoroscopy and angiography, in which radiation injury is inevitable. We present a patient, with a CAF from the left coronary artery to the right atrium, who underwent peratrial device closure of the CAF with a right parasternal approach under transesophageal echocardiography guidance. Complete occlusion was achieved by a symmetric ventricular septal occluder. We suggest that peratrial device closure of a congenital coronary artery fistula through a right parasternal approach may be a safe and effective option.

    To evaluate visualization of the right adrenal vein (RAV) with multidetector CT and non-contrast-enhanced MR imaging in patients with primary aldosteronism. A total of 125 patients (67 men) scheduled for adrenal venous sampling (AVS) were included. Dynamic 64-detector-row CT and balanced steady-state free precession-based non-contrast-enhanced 3-T MR imaging were performed. RAV visualization based on a four-point score was documented. Both anatomical location and variation on cross-sectional imaging were evaluated, and the findings were compared with catheter venography as the gold standard. The RAV was visualized in 93.2% by CT and 84.8% by MR imaging (p = 0.02). Positive predictive values of RAV visualization were 100% for CT and 95.2% for MR imaging. Imaging score was significantly higher in CT than MR imaging (p 70% of subjects. Success rate of AVS was 99.2%. Dynamic CT is a reliable way to map the RAV prior to AVS. Non-contrast-enhanced MR imaging is an alternative when there is a risk of complication from contrast media or radiation exposure. Dynamic CT and non-contrast-enhanced MR imaging detect the right adrenal vein (RAV). Dynamic CT can visualize the RAV more than non-contrast-enhanced MR imaging. Mapping the RAV helps to achieve successful adrenal venous sampling. Sixteen per cent of RAVs share the common trunk with accessory hepatic veins.

  1. Challenge of emerging technologies: balancing the needs of law enforcement against the duty to protect individual rights

    Lingerfelt, James A.

    1997-01-01

    This paper discusses three emerging technologies which will revolutionize the business operations of law enforcement: databases and search engines; biometric identification systems; and electronic surveillance and tracking devices. Unfortunately, these technologies may also lead to a serious ethical conflict for law enforcement. The tools will make it easier than ever to accomplish the core business of policing: crime prevention; investigation; and intelligence gathering. The same tools, used improperly, will also lead to routine intrusions on personal privacy. These technologies have been and are being developed for the private sector, the military and the intelligence community. The vendors are now aggressively marketing them to law enforcement and criminal justice agencies. The law enforcement community has embraced the technology, but without considering the long term impact. In the past, the police have abused wiretaps and other early surveillance technology. As a result, a sinister perception about police surveillance practices persists and a cumbersome bureaucracy has been imposed to control their use. Developing and establishing policies governing the use of emerging technologies can prevent these mistakes from being repeated. This paper recommends that criminal justice practitioners begin a discussion now, in advance of these technologies becoming commercially available, with a view to defining clear guidelines for their proper use.

    So far, the very meaning of health and therefore, treatment and rehabilitation is benchmarked to the normal or species-typical body. We expect certain abilities in members of a species; we expect humans to walk but not to fly, but a bird we expect to fly. However, increasingly therapeutic interventions have the potential to give recipients beyond species-typical body related abilities (therapeutic enhancements, TE). We believe that the perfect storm of TE, the shift in ability expectations toward beyond species-typical body abilities, and the increasing desire of health consumers to shape the health system will increasingly influence various aspects of health care practice, policy, and scholarship. We employed qualitative and quantitative methods to investigate among others how human enhancement, neuro/cognitive enhancement, brain machine interfaces, and social robot discourses cover (a) healthcare, healthcare policy, and healthcare ethics, (b) disability and (c) health consumers and how visible various assessment fields are within Neuro/Cogno/ Human enhancement and within the BMI and social robotics discourse. We found that health care, as such, is little discussed, as are health care policy and ethics; that the term consumers (but not health consumers) is used; that technology, impact and needs assessment is absent; and that the imagery of disabled people is primarily a medical one. We submit that now, at this early stage, is the time to gain a good understanding of what drives the push for the enhancement agenda and enhancement-enabling devices, and the dynamics around acceptance and diffusion of therapeutic enhancements.

    Full Text Available Nowadays, with the rapid development of modern information technology, the college students could not preferably choose and learn to enhance their own art appreciation capability. Therefore, the colleges and universities have a more urgent desire to organize, develop and provide a good platform to enhance the college students’ art appreciation capability based on modern information technology. This paper describes how to enhance the art appreciation capability in detail, and designs and analyzes the platform to enhance college students’ art appreciation capability based on modern information technology---the “Music Corner” and the “Dance Corner”, indicating that the exchange platform built with modern information technology can promotes the college students’ art appreciation capability. Finally, through the analysis of statistical results of the questionnaire, college students are fonder of art appreciation after the establishment of platform, more inclined to the comprehensive learning of art, more brave to express their own sense of art, and fonder of artistic creation.

    Technology-enhanced simulation is used frequently in emergency medicine (EM) training programs. Evidence for its effectiveness, however, remains unclear. The objective of this study was to evaluate the effectiveness of technology-enhanced simulation for training in EM and identify instructional design features associated with improved outcomes by conducting a systematic review. The authors systematically searched MEDLINE, EMBASE, CINAHL, ERIC, PsychINFO, Scopus, key journals, and previous review bibliographies through May 2011. Original research articles in any language were selected if they compared simulation to no intervention or another educational activity for the purposes of training EM health professionals (including student and practicing physicians, midlevel providers, nurses, and prehospital providers). Reviewers evaluated study quality and abstracted information on learners, instructional design (curricular integration, feedback, repetitive practice, mastery learning), and outcomes. From a collection of 10,903 articles, 85 eligible studies enrolling 6,099 EM learners were identified. Of these, 56 studies compared simulation to no intervention, 12 compared simulation with another form of instruction, and 19 compared two forms of simulation. Effect sizes were pooled using a random-effects model. Heterogeneity among these studies was large (I(2) ≥ 50%). Among studies comparing simulation to no intervention, pooled effect sizes were large (range = 1.13 to 1.48) for knowledge, time, and skills and small to moderate for behaviors with patients (0.62) and patient effects (0.43; all p 0.1). Qualitative comparisons of different simulation curricula are limited, although feedback, mastery learning, and higher fidelity were associated with improved learning outcomes. Technology-enhanced simulation for EM learners is associated with moderate or large favorable effects in comparison with no intervention and generally small and nonsignificant benefits in comparison

    Early onset disruptive behavior disorders are overrepresented in low-income families; yet these families are less likely to engage in behavioral parent training (BPT) than other groups. This project aimed to develop and pilot test a technology-enhanced version of one evidence-based BPT program, Helping the Noncompliant Child (HNC). The aim was to increase engagement of low-income families and, in turn, child behavior outcomes, with potential cost-savings associated with greater treatment efficiency. Low-income families of 3- to 8-year-old children with clinically significant disruptive behaviors were randomized to and completed standard HNC (n = 8) or Technology-Enhanced HNC (TE-HNC; n = 7). On average, caregivers were 37 years old; 87% were female, and 80% worked at least part-time. More than half (53%) of the youth were boys; the average age of the sample was 5.67 years. All families received the standard HNC program; however, TE-HNC also included the following smartphone enhancements: (a) skills video series, (b) brief daily surveys, (c) text message reminders, (d) video recording home practice, and (e) midweek video calls. TE-HNC yielded larger effect sizes than HNC for all engagement outcomes. Both groups yielded clinically significant improvements in disruptive behavior; however, findings suggest that the greater program engagement associated with TE-HNC boosted child treatment outcome. Further evidence for the boost afforded by the technology is revealed in family responses to postassessment interviews. Finally, cost analysis suggests that TE-HNC families also required fewer sessions than HNC families to complete the program, an efficiency that did not compromise family satisfaction. TE-HNC shows promise as an innovative approach to engaging low-income families in BPT with potential cost-savings and, therefore, merits further investigation on a larger scale.

  13. Interaction Design Beyond the Product : Creating Technology-Enhanced Activity Spaces

    2012-01-01

    The field of interaction design to date has been predominantly concerned with designing products, that is, devices, systems, and more recently services. A growing body of theoretical and empirical analyses suggests that the scope of interaction design needs to be expanded: An explicit concern...... of the field should include not only helping designers create better products but also helping people themselves create better environments for their work, learning, and leisure activities. In this article we argue that expanding the scope of interaction design beyond products requires a revision of some...... between intrinsic and extrinsic technology-enabled practice transformation, and foreground the need for interaction design research and practice to more directly deal with analysis and construction of technology-enhanced activity spaces. The implications of these notions for the research agenda...

    2009-01-01

    For much of the world, truly productive and functional Electronic Health Record Systems (EHRs) remain an elusive goal of the future. Opportunities abound from the visibility provided by the availability of Health Information Technology funding in the U.S. and other countries of the world. Now is the time to seize the initiative to move from the past to the future to design HIT systems that meet the specific needs of each nation of the world in a way that is obtainable and affordable, and that provides an immediate return on investment. We need to move from an electronic system based on the paper-system to an empowering system based on available technology. We need to recognize that the EHR is not just for data storage but needs to become an intelligent, active partner with the healthcare provider and the patient to enhance health. This paper describes the current state of EHRs and addresses challenges for moving into the future.

  17. Improving vaccine registries through mobile technologies: a vision for mobile enhanced Immunization information systems.

    2016-01-01

    Immunization registries or information systems are critical to improving the quality and evaluating the ongoing success of immunization programs. However, the completeness of these systems is challenged by a myriad of factors including the fragmentation of vaccine administration, increasing mobility of individuals, new vaccine development, use of multiple products, and increasingly frequent changes in recommendations. Mobile technologies could offer a solution, which mitigates some of these challenges. Engaging individuals to have more control of their own immunization information using their mobile devices could improve the timeliness and accuracy of data in central immunization information systems. Other opportunities presented by mobile technologies that could be exploited to improve immunization information systems include mobile reporting of adverse events following immunization, the capacity to scan 2D barcodes, and enabling bidirectional communication between individuals and public health officials. Challenges to utilizing mobile solutions include ensuring privacy of data, access, and equity concerns, obtaining consent and ensuring adoption of technology at sufficiently high rates. By empowering individuals with their own health information, mobile technologies can also serve as a mechanism to transfer immunization information as individuals cross local, regional, and national borders. Ultimately, mobile enhanced immunization information systems can help realize the goal of the individual, the healthcare provider, and public health officials always having access to the same immunization information.

  2. Wireless Keypads - A New Classroom Technology Using Enhanced Multiple-Choice Questions

    CERN Document Server

    Burnstein, R A

    2008-01-01

    This article discusses the advantages of using wireless keypads in the Lecture/classroom. This new technology requires multiple-choice (MC) questions to mate with the keypad entry features of these devices. The format of the traditional MC response is constrained to five choices and only one best response is allowed. For this reason, we propose enhancements to the traditional MC question. This enhanced MC question allows as many as ten answers. The answers can vary in their degree of correctness and can be assigned partial credit. By combining wireless keypads and multiple-choice questions, we can readily perform both formative and summative assessments of student learning. Examples and classroom applications are presented.

    The atomic layer deposition (ALD) technology is introduced to enhance the sensitivity of optical fiber cladding mode to surrounding refractive index (SRI) variation. The highly uniform Al2O nanofilm was deposited around the double cladding fiber (DCF) which presents cladding mode resonant feature. With the high refractive index coating, the cladding mode resonant spectrum was tuned. And the sensitivity enhancement for SRI sensor was demonstrated. Through adjusting the deposition cycles, a maximum sensitivity of 723 nm/RIU was demonstrated in the DCF with 2500 deposition cycles at the SRI of 1.34. Based on the analysis of cladding modes reorganization, the cladding modes transition of the coated DCF was investigated theoretically. With the high performance nanofilm coating, the proposed SRI sensor is expected to have wide applications in chemical sensors and biosensors.

  10. Is it necessary to raise awareness about technologically enhanced naturally occurring radioactive materials?

    Science.gov (United States)

    Michalik, Bogusław

    2009-10-01

    Since radiation risks are usually considered to be related to nuclear energy, the majority of research on radiation protection has focused on artificial radionuclides in radioactive wastes, spent nuclear fuel or global fallout caused by A-bomb tests and nuclear power plant failures. Far less attention has been paid to the radiation risk caused by exposure to ionizing radiation originating from natural radioactivity enhanced due to human activity, despite the fact that technologically enhanced naturally occurring radioactive materials are common in many branches of the non-nuclear industry. They differ significantly from "classical" nuclear materials and usually look like other industrial waste. The derived radiation risk is usually associated with risk caused by other pollutants and can not be controlled by applying rules designed for pure radioactive waste. Existing data have pointed out a strong need to take into account the non-nuclear industry where materials containing enhanced natural radioactivity occur as a special case of radiation risk and enclose them in the frame of the formal control. But up to now there are no reasonable and clear regulations in this matter. As a result, the non-nuclear industries of concern are not aware of problems connected with natural radioactivity or they would expect negative consequences in the case of implementing radiation protection measures. The modification of widely comprehended environmental legislation with requirements taken from radiation protection seems to be the first step to solve this problem and raise awareness about enhanced natural radioactivity for all stakeholders of concern.

    Hale, L. Vincent

    1995-01-01

    The Teacher Enhancement Institute (TEI), under the direction of the Center Education Programs Officer offered three two-week workshops to 58 elementary and middle school teachers in science, math, and technology using the Problem Based Learning Model. The 1995 program was designed with input from evaluations and recommendations from previous TEI participants and faculty. The TEI focused on Aviation and Aeronautics as the unifying theme. Four specific objectives were developed. After completing the requirements for the TEI, the participants should be able to: (1) Increase their content knowledge, particularly in aeronautics, science, math, and technology; (2) Design and implement lessons that use scientific inquiry through Problem Based Learning; (3) Demonstrate knowledge of instructional technologies, their uses, and applications to curricula; and (4) Disseminate to their school communities the information acquired through the TEI. Thirty percent of the program was devoted to the effective use of computer technology. SpaceLink, the NASA telecomputing service for educators, was the primary tool used in the technology component of the institute. The training focused on the use of SpaceLink and its many educational services, and Internet tools because of its universal, nongraphical link to any computer plafform the participant may use at his or her school or home. All participants were given Educator Accounts to facilitate the use of E-mail, and access to the Internet and the World Wide Web using their SpaceLink accounts. Classroom demonstrations used videotaped guides and handouts to support concepts presented followed by intensive hands-on activities. Each participant was assigned to an individual Power Mac networked workstation and introduced to the state of the art, graphical, Word Wide Web with the Netscape browser. The methodology proved very effective in reaching the program's goals for technology integration by having the participants learn to use the computer

    Full Text Available This paper examines issues around learning ‘content’ and its place in the new digital learning culture. We focus on the increasing demands of digital learners for content that is relevant and the challenges this poses if educators are to stay relevant to them. We say ‘relevance’ is best achieved when content is negotiated with learners in collaboration with instructors. We describe strategies in which technology enhanced teaching and learning solutions have enabled learners to negotiate and create digitised learning content that is educationally, culturally and socially relevant. We cite two case studies that exemplify this approach: a trial of negotiated content with primary school aged digital learners at Brisbane School of Distance Education (BSDE, Australia, and the content decision-making processes used for the development of e-learning courses for hearing health professionals and Auditory-Verbal Therapy at Hear and Say WorldWide Brisbane, Australia. We focus on the changing demands and skill sets of digital learners, their learning managers and subject matter experts, and the use of technology enhanced teaching and learning solutions as the negotiating tool in the development of digital content that is academically rigorous and also learner friendly.

    Gas-permeable membrane technology is useful to recover ammonia from manure. In this study, the technology was enhanced using aeration instead of alkali chemicals to increase pH and the ammonium (NH4(+)) recovery rate. Digested effluents from covered anaerobic swine lagoons containing 1465-2097 mg NH4(+)-N L(-1) were treated using submerged membranes (0.13 cm(2) cm(-3)), low-rate aeration (120 mL air L-manure(-1) min(-1)) and nitrification inhibitor (22 mg L(-1)) to prevent nitrification. The experiment included a control without aeration. The pH of the manure with aeration rose from 8.6 to 9.2 while the manure without aeration decreased from 8.6 to 8.1. With aeration, 97-99% of the NH4(+) was removed in about 5 days of operation with 96-98% recovery efficiency. In contrast, without aeration it took 25 days to treat the NH4(+). Therefore, the recovery of NH4(+) was five times faster with the low-rate aeration treatment. This enhancement could reduce costs by 70%.

  5. Nuclear power is neither right nor wrong: the case for a tertium datur in the ethics of technology.

    Science.gov (United States)

    Hillerbrand, Rafaela; Peterson, Martin

    2014-06-01

    The debate over the civilian use of nuclear power is highly polarised. We argue that a reasonable response to this deep disagreement is to maintain that advocates of both camps should modify their positions. According to the analysis we propose, nuclear power is neither entirely right nor entirely wrong, but rather right and wrong to some degree. We are aware that this non-binary analysis of nuclear power is controversial from a theoretical point of view. Utilitarians, Kantians, and other moral theorists make sharp, binary distinctions between right and wrong acts. However, an important argument speaking in favour of our non-binary analysis is that it better reflects our considered intuitions about the ethical trade-offs we face in discussions of nuclear power. The aim of this article is to make this argument sharp by explaining how it can be rendered compatible with, and supported by, the Capability Approach, which is quickly becoming one of the most influential frameworks for thinking about human development.

    2017-10-01

    This study proposed a novel free ammonia (FA, i.e., NH3 ) pretreatment technology to enhance anaerobic methane production from primary sludge for the first time. The solubilization of primary sludge was substantially enhanced following 24 h FA pretreatment (250-680 mg NH3 -N/L), by which the release of soluble chemical oxygen demand (SCOD) (i.e., 0.4 mg SCOD/mg VS added; VS: volatile solids) was approximately 10 times as much as that without pretreatment (i.e., 0.03 mg SCOD/mg VS added). Then, biochemical methane potential (BMP) tests demonstrated that FA pretreatment of 250-680 mg NH3 -N/L was capable of enhancing anaerobic methane production while the digestion time was more than 7 days. Model based analysis indicated that the improved anaerobic methane production was due to an increased biochemical methane potential (B0 ) of 8-17% (i.e., from 331 to 357-387 L CH4 /kg VS added), with the highest B0 achieved at 420 mg NH3 -N/L pretreatment. However, FA pretreatment of 250-680 mg NH3 -N/L decreased hydrolysis rate (k) by 24-38% compared with control (i.e., from 0.29 d(-1) to 0.18-0.22 d(-1) ), which explained the lower methane production over the first 7 days' digestion period. Economic analysis and environmental evaluation demonstrated that FA pretreatment technology was environmentally friendly and economically favorable. Biotechnol.

    2011-07-01

    In this paper, we report on the major accomplishments of the U.S. Department of Energy's (DOE) Solar Energy Technologies Program (SETP) Photovoltaic (PV) Technology Incubator project. The Incubator project facilitates a company's transition from developing a solar cell or PV module prototype to pilot- and large-scale U.S. manufacturing. The project targets small businesses that have demonstrated proof-of-concept devices or processes in the laboratory. Their success supports U.S. Secretary of Energy Steven Chu's SunShot Initiative, which seeks to achieve PV technologies that are cost-competitive without subsidies at large scale with fossil-based energy sources by the end of this decade. The Incubator Project has enhanced U.S. PV manufacturing capacity and created more than 1200 clean energy jobs, resulting in an increase in American economic competitiveness. The investment raised to date by these PV Incubator companies as a result of DOE's $ 59 million investment totals nearly $ 1.3 billion.

Mechanisms were implemented to bring distance students into campus-based medicinal chemistry classrooms in real time, stimulate interaction between instructors and various student cohorts, and promote group work during class. Also, pharmacy clinician colleagues were recruited to contribute to the teaching of the 3 medicinal chemistry courses.Assessment. Student perceptions on the value of technology to build community and advance learning were gleaned from course evaluations, in class feedback, and conversations with class officers and student groups. Responses on a survey of second-year students confirmed the benefits of interdisciplinary content integration on engagement and awareness of the connection between drug chemistry and pharmacy practice. A survey of clinician colleagues who contributed to teaching the 3 medicinal chemistry courses found their views were similar to those of students.Conclusions. The purposeful use of technology united learners, fostered communication, and advanced content comprehension in 3 medicinal chemistry courses taught to campus and distance students. Teaching collaboration with pharmacy clinicians enhanced learner interest in course content and provided insight into the integrated nature of the profession of pharmacy.

  11. Finding an optimal rehabilitation paradigm after stroke: Enhancing fiber growth and training of the brain at the right moment

    Directory of Open Access Journals (Sweden)

    Anna-Sophia eWahl

    2014-06-01

    Full Text Available After stroke the central nervous system reveals a spectrum of intrinsic capacities to react as a highly dynamic system which can change the properties of its circuits, form new contacts, erase others, and remap related cortical and spinal cord regions. This plasticity can lead to a surprising degree of spontaneous recovery. It includes the activation of neuronal molecular mechanisms of growth and of extrinsic growth promoting factors and guidance signals in the tissue. Rehabilitative training and pharmacological interventions may modify and boost these neuronal processes, but almost nothing is known on the optimal timing of the different processes and therapeutic interventions and on their detailed interactions. Finding optimal rehabilitation paradigms requires an optimal orchestration of the internal processes of re‐organization and the therapeutic interventions in accordance with defined plastic time windows.In this review we summarize the mechanisms of spontaneous plasticity after stroke and experimental interventions to enhance growth and plasticity, with an emphasis on anti‐Nogo‐A immunotherapy. We highlight critical time windows of growth and of rehabilitative training and consider different approaches of combinatorial rehabilitative schedules. Finally, we discuss potential future strategies for designing repair and rehabilitation paradigms by introducing a 3 step model: determination of the metabolic and plastic status of the brain, pharmacological enhancement of its plastic mechanisms, and stabilization of newly formed functional connections by rehabilitative training.

    2015-09-04

    This article explores the changing landscape of early pediatric powered mobility. We specifically focus on key indicators that suggest pediatric powered mobility technology (PMT) practice for very young children is poised for a radical paradigm shift. This shift will challenge the current purview of PMT design and function, how it is obtained, and its introduction to children and their families. We propose that this positive, yet radical shift is essential in achieving a standard of practice in which PMT provides for early exploration and participation for children with disabilities at an age concomitant with their non-disabled peers, and within socially inclusive environments. To sustain this new standard, we must acknowledge the significant disconnect that currently exists between clinical research supporting the use of PMT with very young children, and barriers to widespread device access, effective user-driven design and positive social perception of PMT. In this article, we discuss three areas that are particularly important for both shift and sustained change: the history and current availability of novel and conventional PMT devices, pediatric PMT policies and the role of children and families as primary stakeholders in PMT practices. Within each area, we suggest barriers, facilitators and future directions. Implications for Rehabilitation The time is right for reframing how powered mobility technology for very young children is conceived, designed, and implemented. In order for multiple innovative devices to survive in the powered mobility industry, it is important to continue to show the benefits of early powered mobility use for both traditional and non-traditional users, and also enact and enforce policy that promotes sustainable access and financial support for powered mobility technology. The experiences of children and families and the realities of everyday use of powered mobility technology must be brought to the forefront of a movement toward user

    2014-01-01

    Full Text Available A compact patch antenna with stacked parasitic strips (SPSs based on low temperature cofired ceramic (LTCC technology is presented. By adding three pairs of SPSs above the traditional patch antenna, multiple resonant modes are excited to broaden the bandwidth. At the same time, the SPSs act as directors to guide the antenna radiation toward broadside direction to enhance the gain. The measured results show that the prototype antenna achieves an impedance bandwidth of 16% for S11<-10 dB (32.1–37.9 GHz and a maximum gain of about 8 dBi at 35 GHz. Furthermore, the radiation patterns and gain are relatively stable within the operating bandwidth. The total volume of the antenna is only 8 × 8 × 1.1 mm3.

    2011-10-01

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

    2013-10-01

    Full Text Available Higher education institutions (HEIs increasingly use technology-enhanced learning (TEL environments (e.g. blended learning and e-learning to improve student throughput and retention rates. As the demand for TEL courses increases, expectations rise for faculty to meet the challenge of using TEL effectively. The promises that TEL holds have not yet materialized, as not enough faculty master the skills and knowledge to integrate TEL into their teaching and learning. The role of emotional intelligence (EI in attaining TEL in e-learning and blended learning environments is not yet clear. This article reports a case study at a South African university where the former Department of Telematic Education introduced a program to prepare faculty for the implementation of TEL for ODL. This research explores and describes links between emotional intelligence and faculty’s ability to cope with new learning technologies. The purposive sampling comprised ten participants who completed a set of e-activities. A mixed methods approach triangulated the findings which provided insight into the coping tactics participants used to accomplish TEL for ODL. Five trends emerged: perception of adequate ability, cognitive decision making; perception of stressful situations; emotional disclosure; and social networking. Although the study identified links between emotional intelligence and coping strategies, the interdependency of coping strategies and emotional intelligence remains elusive.

    Full Text Available One of the integrative indicators of over-all performance estimation is profitability of the production. It is possible to increase competitiveness of beekeeping production as well as national food security via implementation of efficient electrical technologies. Enhancing of microclimate parameters in hives allows us to enhance the intensity of spring development of bees. The counting of integrate heat losses in heaves with ozone treatment and without the one was carried out. Using the obtained results and graphs we can develop the automation system for in-heave microclimate control. The article presents the graphs of heat losses in a beehive on the outdoor temperature and relative humidity, which were obtained experimental. It is proved that when the outdoor temperature from -15 to 8 ° C and the change in ambient air humidity of 60 to 100% heat loss beehive decrease from 4-5 W to 0.2-0.4 W. It is concluded that treatment of bees by ozone, while reducing the concentration of pathogenic microorganisms, will reduce the energy loss by reducing the air exchange, i.e. improve conditions for the development of the bee colony

    1991-01-01

    Trends in the type and number of US enhanced oil recovery (EOR) projects are analyzed for the period from 1980 through 1989. The analysis is based on current literature and news media and the Department of Energy (DOE) EOR Project Data Base, which contains information on over 1,348 projects. The characteristics of the EOR projects are grouped by starting date and process type to identify trends in reservoir statistics and applications of process technologies. Twenty-two EOR projects starts were identified for 1989 and ten project starts for 1988. An obvious trend over recent years has been the decline in the number of project starts since 1981 until 1988 which corresponds to the oil price decline during that period. There was a modest recovery in 1989 of project starts, which lags the modest recovery of oil prices in 1987 that was reconfirmed in 1989. During the time frame of 1980 to 1989, there has been a gradual improvement in costs of operation for EOR technology. The perceived average cost of EOR has gone down from a $30/bbl range to low $20/bbl. These costs of operation seems to stay just at the price of oil or slightly above to result in marginal profitability. The use of polymer flooding has drastically decreased both in actual and relative numbers of project starts since the oil price drop in 1986. Production from polymer flooding is down more than 50%. Long-term plans for large, high-cost projects such as CO{sub 2} flooding in West Texas, steamflooding in California, and hydrocarbon flooding on the North Slope have continued to be implemented. EOR process technologies have been refined to be more cost effective as shown by the continued application and rising production attributable to EOR. 8 refs., 6 figs., 13 tabs.

  13. Technology-Enhanced Science Partnership Initiative: Impact on Secondary Science Teachers

    2017-07-01

    The issue of student disengagement in school science continues to pose a threat to lifting the participation rates of students undertaking STEM courses and careers in Australia and other countries globally. In Australia, several science initiatives to reverse the problem have been funded over the last two decades. Many of these initiatives involve partnerships with scientists, science educators and with industries, as is the case in this paper. The research in this paper investigated a recent partnership initiative between secondary science teachers, scientists and an educational technology company to produce science e-modules on adaptive learning platforms, enabling students to engage in personalised, inquiry-based learning and the investigation of real-world problems. One of the objectives of the partnership project was to build theoretical and pedagogical skills in teachers to deliver science by exposing them to new ways of engaging students with new digital tools, for example analytics. Using a mixed methods approach, the research investigated science teachers' pedagogical involvement in the partnership project and their perceptions of the project's impact on their teaching and students' learning. The findings indicate that the teachers believed that new technology could enhance their teaching and students' learning and that while their students were motivated by the online modules, there was still a need for scaffolding for many of the students. The effectiveness of this would depend on the teachers' ability to internalise the new technological and content knowledge resulting from the partnership and realign them with their existing pedagogical framework. The research is significant in identifying elements for successful partnership projects as well as challenges that need to be considered. It is significant in facilitating continuous discourse about new evidence-based pedagogical approaches to science education in engaging students to learn STEM subjects in a

    We present a case of a double-chambered right ventricle in adulthood, in which we tried a detailed morphological assessment and preoperative simulation using 3-dimensional (3D) heart models for improved surgical planning. Polygonal object data for the heart were constructed from computed tomography images of this patient, and transferred to a desktop 3D printer to print out models in actual size. Medical staff completed all of the work processes. Because the 3D heart models were examined by hand, observed from various viewpoints and measured by callipers with ease, we were able to create an image of the complete form of the heart. The anatomical structure of an anomalous bundle was clearly observed, and surgical approaches to the lesion were simulated accurately. During surgery, we used an incision on the pulmonary infundibulum and resected three muscular components of the stenosis. The similarity between the models and the actual heart was excellent. As a result, the operation for this rare defect was performed safely and successfully. We concluded that the custom-made model was useful for morphological analysis and preoperative simulation.

    To evaluate visualization of the right adrenal vein (RAV) with multidetector CT and non-contrast-enhanced MR imaging in patients with primary aldosteronism. A total of 125 patients (67 men) scheduled for adrenal venous sampling (AVS) were included. Dynamic 64-detector-row CT and balanced steady-state free precession-based non-contrast-enhanced 3-T MR imaging were performed. RAV visualization based on a four-point score was documented. Both anatomical location and variation on cross-sectional imaging were evaluated, and the findings were compared with catheter venography as the gold standard. The RAV was visualized in 93.2 % by CT and 84.8 % by MR imaging (p = 0.02). Positive predictive values of RAV visualization were 100 % for CT and 95.2 % for MR imaging. Imaging score was significantly higher in CT than MR imaging (p < 0.01). The RAV formed a common trunk with an accessory hepatic vein in 16 % of patients. The RAV orifice level on cross-sectional imaging was concordant with catheter venography within the range of 1/3 vertebral height in >70 % of subjects. Success rate of AVS was 99.2 %. Dynamic CT is a reliable way to map the RAV prior to AVS. Non-contrast-enhanced MR imaging is an alternative when there is a risk of complication from contrast media or radiation exposure. (orig.)

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

    Science.gov (United States)

    Chang, Wenwu

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

  20. Using collaborative technology to enhance pre-service teachers' pedagogical content knowledge in Science

    Donnelly, Dermot Francis; Hume, Anne

    2015-01-01

    Background:Supporting pre-service teacher (PT) collaboration as a means of professional learning is a challenging but essential task for effective practice. However, teacher placements or practicums in schools, which is common practice within teacher education programmes, can often isolate PTs from sharing their experiences with each other. Further, the articulation of effective pedagogical practices by high-quality teachers is limited, restricting PTs' ability to access such professional knowledge. Purpose:This study investigates how the introduction of a collaborative technology, a wiki, may enhance existing and new opportunities for pre-service teachers' (PTs) to develop pedagogical content knowledge (PCK). Sample:Seven PT chemistry teachers of varied backgrounds participated in this study. Design and method:The PTs were learning to collaboratively formulate and document their early topic-specific teaching knowledge using a pedagogical tool known as Content Representation (CoRe) design. Once scaffolded into this process, the PTs continued and extended this collaborative work online through the introduction of a wiki. Data were collected for qualitative analysis through the CoRe artefacts, a semi-structured focus group interview, and PTs' reflective essays about their collaborative experiences representing their teaching knowledge in CoRes through the wiki. Results:Data analysis highlighted that while wiki use showed some potential for collaborative representation when participants were not face-to-face, the PTs were hesitant in critiquing each other's work. As such, the online representations remained relatively static without face-to-face interaction. However, developing artefacts online was favoured over established practice and the access to artefacts of their peers on the wiki enhanced PTs' consideration for their own PCK. Conclusion:Wikis show some potential in the hosting of CoRes, but issues in simultaneous posting and lack of chat functionality may

    direct veteran feedback that depict patient preferences for enhancing the synchronization, integration, and standardization of VA patient-facing platforms. Focus group topics include current uses, preferences, facilitators, and barriers to using electronic health resources; recommendations for synchronizing, integrating, and standardizing VA HIT; and preferences on data sharing and delegation within the VA system. This work highlights the practical, technological, and personal factors that facilitate and inhibit use of current VA HIT, and informs an integrated system redesign. The Digital Health Matrix Model and visual modeling simulations use knowledge of veteran preferences and experiences to directly inform enhancements to VA HIT and provide a more holistic and integrated user experience. These efforts are designed to support the adoption and sustained use of VA HIT to support patient self-management and clinical care coordination in ways that are directly aligned with veteran preferences.

  2. FULL-SCALE TESTING OF ENHANCED MERCURY CONTROL TECHNOLOGIES FOR WET FGD SYSTEMS

    Wet flue gas desulfurization (wet FGD) systems are currently installed on about 25% of the coal-fired utility generating capacity in the U.S., representing about 15% of the number of coal-fired units. Depending on the effect of operating parameters such as mercury content of the coal, form of mercury (elemental or oxidized) in the flue gas, scrubber spray tower configuration, liquid-to-gas ratio, and slurry chemistry, FGD systems can provide cost-effective, near-term mercury emissions control options with a proven history of commercial operation. For boilers already equipped with FGD systems, the incremental cost of any vapor phase mercury removal achieved is minimal. To be widely accepted and implemented, technical approaches that improve mercury removal performance for wet FGD systems should also have low incremental costs and have little or no impact on operation and SO{sub 2} removal performance. The ultimate goal of the Full-scale Testing of Enhanced Mercury Control for Wet FGD Systems Program was to commercialize methods for the control of mercury in coal-fired electric utility systems equipped with wet flue gas desulfurization (wet FGD). The program was funded by the U.S. Department of Energy's National Energy Technology Laboratory, the Ohio Coal Development Office within the Ohio Department of Development, and Babcock & Wilcox. Host sites and associated support were provided by Michigan South Central Power Agency (MSCPA) and Cinergy. Field-testing was completed at two commercial coal-fired utilities with wet FGD systems: (1) MSCPA's 55 MW{sub e} Endicott Station and (2) Cinergy's 1300 MW{sub e} Zimmer Station. Testing was conducted at these two locations because of the large differences in size and wet scrubber chemistry. Endicott employs a limestone, forced oxidation (LSFO) wet FGD system, whereas Zimmer uses Thiosorbic{reg_sign} Lime (magnesium enhanced lime) and ex situ oxidation. Both locations burn Ohio bituminous coal.

    To develop a high-resolution, 3D late gadolinium enhancement (LGE) cardiovascular magnetic resonance imaging (MRI) technique for improved assessment of myocardial scars, and evaluate its performance against 2D breath-held (BH) LGE MRI using a surgically implanted animal scar model in the right ventricle (RV). A k-space segmented 3D LGE acquisition using CENTRA-PLUS (Contrast ENhanced Timing Robust Acquisition with Preparation of LongitUdinal Signal; or CP) ordering is proposed. 8 pigs were surgically prepared with cardiac patch implantation in the RV, followed in 60days by 1.5T MRI. LGE with Phase-Sensitive Inversion Recovery (PSIR) were performed as follows: 1) 2DBH using pneumatic control, and 2) navigator-gated, 3D free-breathing (3DFB)-CP-LGE with slice-tracking. The animal heart was excised immediately after cardiac MR for scar volume quantification. RV scar volumes were also delineated from the 2DBH and 3DFB-CP-LGE images for comparison against the surgical standard. Apparent scar/normal tissue signal-to-noise ratio (aSNR) and contrast-to-noise ratio (aCNR) were also calculated. 3DFB-CP-LGE technique was successfully performed in all animals. No difference in aCNR was noted, but aSNR was significantly higher using the 3D technique (pCP-LGE-derived delineation yielded significantly less volume quantification error compared to 2DBH-derived volumes (15±10% vs 55±33%; p<0.05). Compared to conventional 2DBH-LGE, 3DFB-LGE acquisition using CENTRA-PLUS provided superior scar volume quantification and improved aSNR. Copyright © 2017 Elsevier Inc. All rights reserved.

    Milk is a major source of nutrients, but can also be a vehicle for zoonotic foodborne diseases, especially when raw milk is consumed. In Africa, poor processing and storage conditions contribute to contamination, outgrowth and transmission of pathogens, which lead to spoilage, reduced food safety and security. Fermentation helps mitigate the impact of poor handling and storage conditions by enhancing shelf life and food safety. Traditionally-fermented sour milk products are culturally accepted and widely distributed in Africa, and rely on product-specific microbiota responsible for aroma, flavor and texture. Knowledge of microbiota and predominant, technologically important microorganisms is critical in developing products with enhanced quality and safety, as well as sustainable interventions for these products, including Africa-specific starter culture development. This narrative review summarizes current knowledge of technologically-important microorganisms of African fermented dairy products (FDP) and raw milk, taking into consideration novel findings and taxonomy when re-analyzing data of 29 publications covering 25 products from 17 African countries. Technologically-important lactic acid bacteria such as Lactococcus lactis and Streptococcus infantarius subsp. infantarius (Sii), Lactobacillus spp. and yeasts predominated in raw milk and FDP across Africa. Re-analysis of data also suggests a much wider distribution of Sii and thus a potentially longer history of use than previously expected. Therefore, evaluating the role and safety of African Sii lineages is important when developing interventions and starter cultures for FDP in Africa to enhance food safety and food security. In-depth functional genomics, epidemiologic investigations and latest identification approaches coupled with stakeholder involvement will be required to evaluate the possibility of African Sii lineages as novel food-grade Streptococcus lineage.

    Full Text Available This study investigates the level of technological enhancement of normally occurring radioactive materials (TENORM in the red mud waste due to the production of alumina in Jamaica. Technological enhancements factors (TEF were determined for the uranium, thorium, actinium series, their progenies, and the nonseries potassium-40 using gamma spectrometry. The study concluded that bauxite production technologically enhances the uranium progenies Th-234, Pb-214, Bi-214, and Pa-234 and the thorium-232 progenies Ac-228, Pb-212, and Bi-212 in red mud. The actinium series was technologically enhanced, but K-40 and the thorium daughter, Tl-208, were reduced. The spectrometric comparison of Tl-208 (at 510 keV was unexpected since its other photopeaks at 583 keV, 934 keV, and 968 keV were markedly different. An explanation for this anomaly is discussed. An explanation regarding the process of accumulation and fractionation of organically derived phosphate deposits and potassium-feldspar is offered to explain the spectrometric differences between the alumina product and its waste material, red mud.

  17. Regulatory Initiatives for Control and Release of Technologically Enhanced Naturally-Occurring Radioactive Materials

    1999-03-02

    Current drafts of proposed standards and suggested State regulations for control and release of technologically-enhanced naturally-occurring radioactive material (TENORM), and standards for release of volumetrically-contaminated material in the US are reviewed. These are compared to the recommendations of the International Atomic Energy Association (IAEA) Safety Series and the European Commission (EC) proposals. Past regulatory efforts with respect to TENORM in the US dealt primarily with oil-field related wastes. Currently, nine states (AK, GA, LA, MS, NM, OH, OR SC, TX) have specific regulations pertaining to TENORM, mostly based on uranium mill tailings cleanup criteria. The new US proposals are dose- or risk-based, as are the IAEA and EC recommendations, and are grounded in the linear no threshold hypothesis (LNT). TENORM wastes involve extremely large volumes, particularly scrap metal and mine wastes. Costs to control and dispose of these wastes can be considerable. The current debate over the validity of LNT at low doses and low dose rates is particularly germane to this discussion. Most standards setting organizations and regulatory agencies base their recommendations on the LNT. The US Environmental Protection Agency has released a draft Federal Guidance Report that recommends calculating health risks from low-level exposure to radionuclides based on the LNT. However, some scientific and professional organizations are openly questioning the validity of LNT and its basis for regulations, practices, and costs to society in general. It is not clear at this time how a non-linear regulatory scheme would be implemented.

  18. The Role of Facilitation in Technology-Enhanced Learning for Public Employment Services

    Full Text Available Public Employment Services (PES in Europe are authorities that attempt to match supply and demand on the labor market. Rising unemployment in times of crisis and demographic change are among the main challenges with which PES practitioners, as a direct interface between jobseekers and employers, have to deal. They have to support career adaptability of their clients as well as to enhance and transform their own individual and collective professional identities in order to cope successfully with the challenges of a changing labor market. As part of the research project EmployID, we are exploring how to facilitate the learning process of PES practitioners in their professional identity development. The aim of the project is to empower individual PES practitioners, their community and organizations, to engage in transformative practices, using a holistic tool suite combining e-coaching, reflection, MOOCs, networking, analytical and learning support tools. Key to successful professional identity transformation is continuous learning. Individuals may take on the role of facilitators for the learning of others as well as being facilitated by peers, technology and environment.

    This study offers an innovative and sustainable instructional model for an introductory undergraduate course. The model was gradually implemented during 3 yr in a research university in a large-lecture biology course that enrolled biology majors and nonmajors. It gives priority to sources not used enough to enhance active learning in higher education: technology and the students themselves. Most of the lectures were replaced with continuous individual learning and 1-mo group learning of one topic, both supported by an interactive online tutorial. Assessment included open-ended complex questions requiring higher-order thinking skills that were added to the traditional multiple-choice (MC) exam. Analysis of students' outcomes indicates no significant difference among the three intervention versions in the MC questions of the exam, while students who took part in active-learning groups at the advanced version of the model had significantly higher scores in the more demanding open-ended questions compared with their counterparts. We believe that social-constructivist learning of one topic during 1 mo has significantly contributed to student deep learning across topics. It developed a biological discourse, which is more typical to advanced stages of learning biology, and changed the image of instructors from "knowledge transmitters" to "role model scientists."

    2014-05-01

    Bombyx mori is a common lepidopteran model and an important economic insect for silk production. B. mori nucleopolyhedrovirus (BmNPV) is a typical pathogenic baculovirus that causes serious economic losses in sericulture. B. mori and BmNPV are a model of insect host and pathogen interaction including invasion of the host by the pathogen, host response, and enhancement of host resistance. The antiviral capacity of silkworms can be improved by transgenic technology such as overexpression of an endogenous or exogenous antiviral gene, RNA interference of the BmNPV gene, or regulation of the immune pathway to inhibit BmNPV at different stages of infection. Antiviral capacity could be further increased by combining different methods. We discuss the future of an antiviral strategy in silkworm, including possible improvement of anti-BmNPV, the feasibility of constructing transgenic silkworms with resistance to multiple viruses, and the safety of transgenic silkworms. The silkworm model could provide a reference for disease control in other organisms.

    Eight pilots participated as test subjects in a fixed-based simulation experiment to evaluate advanced vision display technologies such as Enhanced Vision (EV) and Synthetic Vision (SV) for providing terrain imagery on flight displays in a Lunar Lander Vehicle. Subjects were asked to fly 20 approaches to the Apollo 15 lunar landing site with four different display concepts - Baseline (symbology only with no terrain imagery), EV only (terrain imagery from Forward Looking Infra Red, or FLIR, and LIght Detection and Ranging, or LIDAR, sensors), SV only (terrain imagery from onboard database), and Fused EV and SV concepts. As expected, manual landing performance was excellent (within a meter of landing site center) and not affected by the inclusion of EV or SV terrain imagery on the Lunar Lander flight displays. Subjective ratings revealed significant situation awareness improvements with the concepts employing EV and/or SV terrain imagery compared to the Baseline condition that had no terrain imagery. In addition, display concepts employing EV imagery (compared to the SV and Baseline concepts which had none) were significantly better for pilot detection of intentional but unannounced navigation failures since this imagery provided an intuitive and obvious visual methodology to monitor the validity of the navigation solution.

  2. Teaching Science Through the Language of Students in Technology-Enhanced Instruction

    This study examines whether and how tapping into students' everyday language in a web-based learning environment can improve all students' science learning in linguistically heterogeneous classrooms. A total of 220 fifth-grade English Language Learners (ELLs) and their non-ELL peers were assigned to either an everyday English approach condition or a textbook approach condition, and completed technology-enhanced instruction focusing on respiration and photosynthesis. Students in the everyday English approach condition were taught the concepts in everyday, conversational English before content-specific scientific terms were introduced, while students in the textbook approach condition were taught the same concepts and vocabulary simultaneously. The results show that the everyday English approach was significantly more effective in helping both ELLs and non-ELL students develop a coherent understanding of abstract concepts related to photosynthesis and respiration. Students in the everyday English approach condition were also better able to link content-specific terms to their understanding of the concepts. These findings show the potential advantage of using students' everyday English as a resource to make science more accessible to linguistically diverse students in mainstream classrooms. By integrating students' everyday language in science instruction, it is possible for all students including ELLs to acquire both the content and language of science.

    This research attempts to enhance students' science literacy in the aspects of students' science content, application context, process, and students' attitude using solar cell learning multimedia containing science and nano technology. The quasi-experimental method with pre-post test design was used to achieve these objectives. Seventy-two students of class XII at a high school were employed as research's subject. Thirty-six students were in control class and another thirty-six were in experiment class. Variance test (t-test) was performed on the average level of 95% to identify the differences of students' science literacy in both classes. As the result, there were significant different of learning outcomes between experiment class and control class. Almost half of students (41.67%) in experiment class are categorized as high. Therefore, the learning using solar cell learning multimedia can improve students' science literacy, especially in the students' science content, application context, and process aspects with n-gain(%) 59.19 (medium), 63.04 (medium), and 52.98 (medium). This study can be used to develop learning multimedia in other science context.

    2009-06-01

    Full Text Available The African Charter to Human and Peoples' Rights is an innovative document as it is the first human rights albeit regional instrument to provide for a substantive right to environment. However, the right as provided under the Charter is encumbered as it is linked to the promotion of development. Such linkage has led to the argument that the right can only be invoked where it will not infringe the requirements of socio-economic development. While this issue appears to have engaged the attention of most commentators, there has not been much enquiry into what the right aims to achieve and the implication for the achievement of sustainable development objectives including environmental protection and poverty reduction in Africa. This article therefore seeks to evaluate the utility of the right to the pursuit of sustainable development objectives in Africa.

     Technology-enhanced simulation is well-established in healthcare teaching curricula, including those regarding wilderness medicine. Compellingly, the evidence base for the value of this educational modality to improve learner competencies and patient outcomes are increasing.  The aim was to systematically review the characteristics of technology-enhanced simulation presented in the wilderness medicine literature to date. Then, the secondary aim was to explore how this technology has been used and if the use of this technology has been associated with improved learner or patient outcomes.  EMBASE and MEDLINE were systematically searched from 1946 to 2014, for articles on the provision of technology-enhanced simulation to teach wilderness medicine. Working independently, the team evaluated the information on the criteria of learners, setting, instructional design, content, and outcomes.  From a pool of 37 articles, 11 publications were eligible for systematic review. The majority of learners in the included publications were medical students, settings included both indoors and outdoors, and the main focus clinical content was initial trauma management with some including leadership skills. The most prevalent instructional design components were clinical variation and cognitive interactivity, with learner satisfaction as the main outcome.  The results confirm that the current provision of wilderness medicine utilizing technology-enhanced simulation is aligned with instructional design characteristics that have been used to achieve effective learning. Future research should aim to demonstrate the translation of learning into the clinical field to produce improved learner outcomes and create improved patient outcomes.

    Full Text Available 著作人格權(moral rights)是指作者基於作品創作而產生的人格利益,與著作財產權同屬著作權法的兩個重要組成部分。近年來隨著功能愈簡便的編輯軟體讓一般人可隨意修改他人作品,輕者斷章取義,重者指鹿為馬,再加上網路複製、傳輸快速的特性,加劇了鼓勵再創作與維持作品完整性之間的矛盾,讓人開始正視資訊科技對著作人格權的影響。另一方面,以文本為主之後現代現象正逐漸成為主流的網路文化,徹底翻轉以作者為中心之傳統詮釋方法,主張作品之價值係來自於讀者之解讀,而非作者之貢獻時,執著於著作人格權之保護似乎又有悖於強調開放、分享、互動、多元、去中心化之網路世界發展,著作人格權理論正面對資訊科技所帶來之「典範移轉」衝擊。 The orthodoxy of moral rights is that authors of copyrightable works have inalienable rights in their works that protect their moral and personal interest. Recently, the problem of moral rights causes new concern because of information technologies. As the function of editor software gets stronger, it is much easier for people to make the modification, distortion or mutilation of copyrighted works which would be prejudicial to authors’ honor or reputation. On the other hand, Postmodernism is a tendency in the network culture characterized by the rejection of the author’s contribution to a work. It emphasizes that essential meaning of a work depends on the impressions of the reader, rather than the “passions” or “tastes” of the writer. Based on this, “Remix” Culture which encourages people to create new works based on existed copyrighted works has become popular on the Internet. The protection of moral rights seems working against the development of network communities whose ethics is the information sharing and decentralization. The development of moral

    The long-term economic potential for enhanced oil recovery (EOR) is large with more than 300 billion barrels of oil remaining in domestic reservoirs after conventional technologies reach their economic limit. Actual EOR production in the United States has never been very large, less than 10% of the total U. S. production even though a number of economic incentives have been used to stimulate the development and application of EOR processes. The U.S. DOE Reservoir Data Base contains more than 600 reservoirs with over 12 billion barrels of unrecoverable oil that are potential targets for microbially enhanced oil recovery (MEOR). If MEOR could be successfully applied to reduce the residual oil saturation by 10% in a quarter of these reservoirs, more than 300 million barrels of oil could be added to the U.S. oil reserve. This would stimulate oil production from domestic reservoirs and reduce our nation's dependence on foreign imports. Laboratory studies have shown that detergent-like molecules called biosurfactants, which are produced by microorganisms, are very effective in mobilizing entrapped oil from model test systems. The biosurfactants are effective at very low concentrations. Given the promising laboratory results, it is important to determine the efficacy of using biosurfactants in actual field applications. The goal of this project is to move biosurfactant-mediated oil recovery from laboratory investigations to actual field applications. In order to meet this goal, several important questions must be answered. First, it is critical to know whether biosurfactant-producing microbes are present in oil formations. If they are present, then it will be important to know whether a nutrient regime can be devised to stimulate their growth and activity in the reservoir. If biosurfactant producers are not present, then a suitable strain must be obtained that can be injected into oil reservoirs. We were successful in answering all three questions. The specific

    Technology-Enhanced Learning (TEL) can be used to educate Foundation Programme trainee (F1 and F2) doctors. Despite the advantages of TEL, learning behaviours may be exhibited that are not desired by system developers or educators. The aim of this evaluation was to investigate how learner behaviours (e.g. time spent on task) were affected by temporal (e.g. time of year), module (e.g. word count), and individual (e.g. knowledge) factors for 16 mandatory TEL modules related to prescribing and therapeutics. Data were extracted from the SCRIPT e-Learning platform for first year Foundation trainee (F1) doctors in the Health Education England's West Midland region from 1(st) August 2013 to 5(th) August 2014. Generalised Estimating Equation models were used to examine the relationship between time taken to complete modules, date modules were completed, pre- and post-test scores, and module factors. Over the time period examined, 688 F1 doctors interacted with the 16 compulsory modules 10,255 times. The geometric mean time taken to complete a module was 28.9 min (95% Confidence Interval: 28.4-29.5) and 1,075 (10.5%) modules were completed in less than 10 min. In February and June (prior to F1 progression reviews) peaks occurred in the number of modules completed and troughs in the time taken. Most modules were completed, and the greatest amount of time was spent on the learning on a Sunday. More time was taken by those doctors with greater pre-test scores and those with larger improvements in test scores. Foundation trainees are exhibiting unintended learning behaviours in this TEL environment, which may be attributed to several factors. These findings can help guide future developments of this TEL programme and the integration of other TEL programmes into curricula by raising awareness of potential behavioural issues that may arise.

    The objective of this study is to develop the automatic ultrasonic signal processing system which can be used in the inspection equipment to assess the integrity of the reactor vessel by enhancing the performance of the ultrasonic signal processing system. Main activities of this study divided into three categories such as the development of the circuits for generating ultrasonic signal and receiving the signal from the inspection equipment, the development of signal processing algorithm and H/W of the data processing system, and the development of the specification for application programs and system S/W for the analysis and evaluation computer. The results of main activities are as follows 1) the design of the ultrasonic detector and the automatic ultrasonic signal processing system by using the investigation of the state-of-the-art technology in the inside and outside of the country. 2) the development of H/W and S/W of the data processing system based on the results. Especially, the H/W of the data processing system, which have both advantages of digital and analog controls through the real-time digital signal processing, was developed using the DSP which can process the digital signal in the real-time, and was developed not only firmware of the data processing system in order for the peripherals but also the test algorithm of specimen for the calibration. The application programs and the system S/W of the analysis/evaluation computer were developed. Developed equipment was verified by the performance test. Based on developed prototype for the automatic ultrasonic signal processing system, the localization of the overall ultrasonic inspection equipment for nuclear industries would be expected through the further studies of the H/W establishment of real applications, developing the S/W specification of the analysis computer.

    Patients with pulmonary hypertension associated with congenital heart disease survive longer with preserved right ventricular (RV) function compared with those with primary pulmonary hypertension. The purpose of this study was to test the hypothesis that superior RV performance can be demonstrated, at baseline and when challenged with increased RV afterload, in lambs with chronic left-to-right cardiac shunts compared with control lambs. A shunt was placed between the pulmonary artery and the aorta in fetal lambs (shunt). RV pressure-volume loops were obtained 4 wk after delivery in shunt and control lambs, before and after increased afterload was applied using pulmonary artery banding (PAB). Baseline stroke volume (8.7 ± 1.8 vs. 15.8 ± 2.7 ml, P = 0.04) and cardiac index (73.0 ± 4.0 vs. 159.2 ± 25.1 ml·min(-1)·kg(-1), P = 0.02) were greater in shunts. After PAB, there was no difference in the change in cardiac index (relative to baseline) between groups; however, heart rate (HR) was greater in controls (168 ± 7.3 vs. 138 ± 6.6 beats/min, P = 0.01), and end-systolic elastance (Ees) was greater in shunts (2.63 vs. 1.31 × baseline, P = 0.02). Control lambs showed decreased mechanical efficiency (71% baseline) compared with shunts. With acute afterload challenge, both controls and shunts maintained cardiac output; however, this was via maladaptive responses in controls, while shunts maintained mechanical efficiency and increased contractility via a proposed enhanced Anrep effect-the second, slow inotropic response in the biphasic ventricular response to increased afterload, a novel finding in the RV. The mechanisms related to these physiological differences may have important therapeutic implications.

    Fragmented QRS (fQRS) on 12-lead electrocardiography reflects conduction delay caused by myocardial fibrosis and dysfunction. Ventricular fibrosis detected by late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) is reportedly correlated with worse clinical outcomes in adults with repaired tetralogy of Fallot (TOF). The aim of this study was to assess whether the presence of fQRS is associated with right ventricular (RV) fibrosis or dysfunction in this patient group. In 37 consecutive patients (median age 30 years, median age at repair 6.6 years), the number of leads showing fQRS, defined as the presence of >2 notches on the R/S wave in ≥2 contiguous leads, was counted. RV systolic function, dilatation, and LGE score were measured using LGE CMR. Ventricular LGE was observed mainly at the previous surgical sites: the RV outflow tract (33 of 37), ventricular septal defect patch region (15 of 37), and RV anterior wall (11 of 37). Fragmented QRS was found mostly in the right and mid precordial leads. The fQRS group (n = 20) demonstrated higher RV LGE scores (p <0.001) and lower RV ejection fractions (p = 0.02) and a trend toward larger RV end-diastolic and end-systolic volumes (p = 0.12 and p = 0.06, respectively) compared to the non-fQRS group (n = 17). The number of electrocardiographic leads showing fQRS was positively correlated with RV LGE score (r = 0.75, p <0.001). The presence of fQRS remained independently associated with the presence of supramedian RV LGE score, even after adjusting for relevant parameters. In conclusion, fQRS was closely associated with more extensive RV fibrosis and dysfunction in adults with repaired tetralogy of Fallot.

    This project has documented and demonstrated the feasibility of technologies and operational choices for companies who operate the large installed fleet of integral engine compressors in pipeline service. Continued operations of this fleet is required to meet the projected growth of the U.S. gas market. Applying project results will meet the goals of the DOE-NETL Natural Gas Infrastructure program to enhance integrity, extend life, improve efficiency, and increase capacity, while managing NOx emissions. These benefits will translate into lower cost, more reliable gas transmission, and options for increasing deliverability from the existing infrastructure on high demand days. The power cylinders on large bore slow-speed integral engine/compressors do not in general combust equally. Variations in cylinder pressure between power cylinders occur cycle-to-cycle. These variations affect both individual cylinder performance and unit average performance. The magnitude of the variations in power cylinder combustion is dependent on a variety of parameters, including air/fuel ratio. Large variations in cylinder performance and peak firing pressure can lead to detonation and misfires, both of which can be damaging to the unit. Reducing the variation in combustion pressure, and moving the high and low performing cylinders closer to the mean is the goal of engine balancing. The benefit of improving the state of the engine ''balance'' is a small reduction in heat rate and a significant reduction in both crankshaft strain and emissions. A new method invented during the course of this project is combustion pressure ratio (CPR) balancing. This method is more effective than current methods because it naturally accounts for differences in compression pressure, which results from cylinder-to-cylinder differences in the amount of air flowing through the inlet ports and trapped at port closure. It also helps avoid compensation for low compression pressure by the

    Weiss Associates is conducting a three phase program investigating the systematics of using acoustic excitation fields (AEFs) to enhance the in-situ remediation of contaminated soil and ground water under both saturated and unsaturated conditions: Phase I - Laboratory Scale Parametric Investigation; Phase II - Technology Scaling Study; and Phase III - Large Scale Field Tests. Phase I, the subject of this paper, consisted primarily of a laboratory proof of principle investigation. The field deployment and engineering viability of acoustically enhanced remediation (AER) technology was also examined. Phase II is a technology scaling study addressing the scale up between laboratory size samples on the order of inches, and the data required for field scale testing, on the order of hundreds of feet. Phase III will consist of field scale testing at an non-industrialized, non-contaminated site and at a contaminated site to validate the technology. Summarized herein are the results of the Phase I {open_quotes}proof-of-principle{close_quotes} investigation, and recommendations for Phase H. A general overview of AER technology along with the plan for the Phase I investigation was presented.

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

    2014-07-01

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

  20. Applying Space Technology to Enhance Control of an Artificial Arm for Children and Adults With Amputations

    Atkins, Diane J.

    1998-01-01

    The first single function myoelectric prosthetic hand was introduced in the 1960's. This hand was controlled by the electric fields generated by muscle contractions in the residual limb of the amputee user. Electrodes and amplifiers, embedded in the prosthetic socket, measured these electric fields across the skin, which increase in amplitude as the individual contracts their muscle. When the myoelectric signal reached a certain threshold amplitude, the control unit activated a motor which opened or closed a hand-like prosthetic terminal device with a pincher grip. Late in the 1990's, little has changed. Most current myoelectric prostheses still operate in this same, single-function way. To better understand the limitations of the current single-function myoelectric hand and the needs of those who use them, The Institute for Rehabilitation and Research (TIRR), sponsored by the National Institutes of Health (NUH), surveyed approximately 2,500 individuals with upper limb loss [1]. When asked to identify specific features of their current myoelectric prostheses that needed improvement, the survey respondents overwhelmingly identified the lack of wrist and finger movement, as well as poor control capability. However, simply building a mechanism with individual finger and wrist motion is not enough. In the 1960's and 1970's, engineers built a number of more dexterous prosthetic hands. Unfortunately, these were rejected during clinical trials due to a difficult and distracting control interface. The goal of this project, "Applying Space Technology to Enhance Control of an Artificial Arm for Children and Adults with Amputations," was to lay the foundation for a multi-function, intuitive myoelectric control system which requires no conscious thought to move the hand. We built an extensive myoelectric signal database for six motions from ten amputee volunteers, We also tested a control system based on new artificial intelligence techniques on the data from two of these
