    1999-12-01

    The pentyloxyterphenyl side chain derivative of echinocandin B, anidulafungin, is a 1,3-alpha-glucan synthesis inhibitor undergoing phase II clinical trials by Versicor and Eli Lilly, in various formulations, for the potential treatment of fungal and protozoal infections. Eli Lilly has retained options to the oral formulation of the compound, but development, clinical registration and marketing rights were licensed to Versicor in June 1999. The primary target of this compound is Candida, but Eli Lilly also intends to develop the drug for Aspergillus infections. No activity has been shown against Cryptococcus. The oral activity of anidulafungin is compromised by a low bioavailability, a decreased absorption when taken with food, and gastrointestinal side effects at higher doses. The development of a phosphorylated prodrug, LY-307853, which is converted in the body to anidulafungin by tissue and serum phosphatases, was discontinued in favor of an oral formulation, which uses anidulafungin directly. In February 1999, Deutsche Bank predicted sales of $100 million in 2001, rising to $300 million in 2003.

  6. Oritavancin. Eli Lilly & Co.

    Barrett, J F

    2001-08-01

    Oritavancin (LY-333328), a lead glycopeptide from a series targeted at vancomycin-resistant bacteria, especially enterococci, is under development by Eli Lilly for the potential treatment of bacterial infections. It entered phase III trials in the US in January 2001 [396223] and the company expects to submit an NDA by 2003 [396478]. Oritavancin has been reported to have activity comparable to that of vancomycin and teicoplanin (Aventis Pharma AG), but retains activity against glycopeptide-resistant bacterial strains [407519]. The bactericidal activity of oritavancin suggests that it may prove useful as a single agent therapy in the treatment of antibiotic-resistant enterococci. Although its mechanism of action is unclear, dimerization of the glycosyl portion stabilizing D-Ala-D-Ala binding has been suggested [337644].

  7. Tomoxetine (Eli Lilly & Co).

    Science.gov (United States)

    Preti, Antonio

    2002-02-01

    Eli Lilly is developing tomoxetine, a norepinephrine reuptake inhibitor, for the potential treatment of attention deficit hyperactivity disorder (ADHD) and depression. As of May 2000, tomoxetine was undergoing phase III trials in the US [368128]. An NDA was filed with the FDA in October 2001, with a launch expected in the second half of 2002 [426786]. Tomoxetine was first investigated by Lilly in the 1980s as a potential treatment for depressive illness. The compound was selected from a series of potent inhibitors of norepinephrine reuptake, and reached large-scale phase II clinical trials for depression in 1990. Development for this indication appeared to stop at that time, despite some evidence that tomoxetine wasfairly effective [273943]. In 1996, Lilly apparently restarted preclinical development of tomoxetine as a potential therapyfor ADHD, and submitted EP-00721777 claiming tomoxetine's utility for this disorder in July of that year [273956]. In June 2001, ABN AMRO predicted sales of $121 million in 2002, rising to $4,064 million in 2012 [422762]. In October 2001, analysts at Salomon Smith Barney predicted that the product would make sales of $24 million in 2002, rising to $305 million in 2005 [427501].

  8. Drotrecogin alfa Eli Lilly.

    Science.gov (United States)

    de Jonge, E

    2002-04-01

    Drotrecogin alfa (Xigris, recombinant activated protein C) is an anticoagulant developed and launched by Eli Lilly & Co for the treatment of sepsis [333781], [339372], [430133], [436271]. The FDA and the EMEA accepted the brand name Xigris for drotrecogin alfa in June 2001. This trade name had been proposed by Lilly in place of the previous brand name, Zovant, which was deemed unacceptable by the EMEA due to concerns that the name could be confused with hospital-based drugs [412512]. Filings for sepsis were made in the US, EU and Australia in February 2001 [398514], [447870] and in March 2001, the US FDA assigned drotrecogin alfa Priority Review status [403435]. The FDA extended the action date from July 27 to October 27, 2001 for completion of its review of the biologics license application (BLA) for drotrecogin alfa to assess further supplementary data submitted by Lilly [412512]. At the October 16, 2001 meeting (postponed from September 12), the FDA Advisory Committee on Anti-Infective Drugs split 10 to 10 over whether to recommend approval [425873], [425940]. In late October 2001, Lilly received an approvable letter from the FDA for the treatment of severe sepsis. Approval was contingent upon successful negotiation of labeling, agreement on post-approval clinical trials, and successful completion of manufacturing inspections [427301]. In November 2001, the FDA approved drotrecogin alfa for the reduction of mortality in adult patients with severe sepsis who have a high risk of death [430133]; the product was launched onto the US market days later [436271]. Following the FDA committee's split decision in October 2001, Credit Suisse First Boston, which expected mid-2002 approval but with restrictive labeling, revised its predictions from $1.265 billion in 2004 sharply downwards to $543 million [425929].

  10. Pemetrexed disodium (Eli Lilly).

    Science.gov (United States)

    Norman, P

    2001-11-01

    Pemetrexed, a thymidylate synthase (TS) and transferase inhibitor, is in phase III trials with Eli Lilly as a potential treatment for several common solid tumors, including non-small cell lung cancer (NSCLC) and mesothelioma [321789], [410731]. Studies on pemetrexed have concluded that not only is the compound a TS inhibitor but also a potent inhibitor of human dihydrofolate reductase (DHFR). The results suggest that pemetrexed acts upon multiple intracellular targets and that the antitumor effect may be derived from its simultaneous inhibition of multiple folate-requiring enzymes [203662]: this compound has been designated as a multitargeted antifolate (MTA) [386680]. The drug also causes concentration- and time-dependent apoptosis [284380]. Other studies in which the 4-oxo group of the pyrimidine ring portion of pemetrexed was replaced with a hydrogen atom, demonstrated that the resulting analogs were potent DHFR inhibitors with very little activity against the enzymes glycinamide ribonucleotide formyltransferase (GARFT) and TS [310674]. In phase II European studies in 64 patients with advanced breast cancer, encouraging responses were seen in anthracycline-failure (23%) and anthracycline-refractory (19%) patients. Responses were observed in 28% of patients who had been previously treated with a taxane [326097]. Data from a phase II trial of pemetrexed (500 mg/m2 once every 21 days as a 10 min i.v. infusion) as a salvage therapy in advanced breast cancer showed that supplementation of the treatment regime with folic acid (FA) and vitamin B12 reduced its already manageable and tolerable toxicities [408821], [409650]. At doses of 500 mg/m2, the drug was also safely administered to 35 patients with impaired renal function [409953]. Phase I and II trials have shown that the main side effects include neutropenia, thrombocytopenia, mucositis, nausea and vomiting [203666], [272241]. Princeton University holds the patent rights to this drug under EP-00432677. In June

    2007-01-01

    We were deeply saddened to hear of the death of our former colleague and friend, Elie Menant, at Collonge-Bellerive, on 17 August, in his 80th year. Formerly of the French National Geographic Institute, for which he had conducted many geodesic surveys throughout France, Elie came to CERN in 1962, joining the team of surveyors led by Jean Gervaise in AR Division. Elie was involved in the PS, ISR, SPS and LEP projects and made a substantial contribution to the development of the group’s alignment techniques. Among the highlights of a richly creative career, we particularly recall his essential contributions to the implementation of the first computer software for the adjustment of major geodesic networks, to new computer-assisted calculation techniques, to the design of the alignment method for the ISR ring and the associated beam transfer lines, as well as his work on the site studies for the 300 GeV project. Last, but not least, his instinct for large-dimension metrolog...

  14. How initial representations shape coupled learning processes

    DEFF Research Database (Denmark)

    Puranam, Phanish; Swamy, M.

    2016-01-01

    Coupled learning processes, in which specialists from different domains learn how to make interdependent choices among alternatives, are common in organizations. We explore the role played by initial representations held by the learners in coupled learning processes using a formal agent-based model....... We find that initial representations have important consequences for the success of the coupled learning process, particularly when communication is constrained and individual rates of learning are high. Under these conditions, initial representations that generate incorrect beliefs can outperform...... one that does not discriminate among alternatives, or even a mix of correct and incorrect representations among the learners. We draw implications for the design of coupled learning processes in organizations. © 2016 INFORMS....

    2010-01-01

    Complete text of publication follows. This contribution attempts to review some results of thinking about prospects for meaningful and procreative research by exploitation the potential of the unique laser technology to be available within the future ELI Beamlines Facility - an ultrashort-pulse, multi-petawatt, multi-beam, high-repetition-rate system. The presentation may be (hopefully) regarded as a specific contribution with the emphasis on two concrete areas to general ELI reports. Two sets of potential studies will be discussed: (1) Realistic experiments. (2) 'Dream' research. The first set (maybe realizable in the first phase of the laboratory work) includes the following topics: (1) Laser-driven electronuclear processes. (2) Unconventional / NLTE fusion reactions. (3) Laser positron / antimatter physics. Most detailed analysis will be presented for the subject. Some concrete themes planned for this part of the talk are: Challenges for laser positronium physics. Nuclear excitation in positron annihilation. Positrons and the laboratory astrophysics. Schemes of some experiments exploiting the ELI Beamlines possibilities will be displayed. The second ('dream') set to be outlined (under consideration as potential one for the second phase) should initiate a brainstorming discussion in these areas: (1) High-Z ion physics studies. (2) Exploring of high-gamma systems. (3) Search for hypothetic particles. Again, the highest attention will be paid to the topic. Key themes in this part: The search for hidden-sector lightweights. Challenges and opportunities in photon regeneration experiments. Potential of ELI Beamlines for the research in this area? The final section of the contribution will include some comments on technical issues related to the proposed research themes: (1) Novel targets and particle traps. (2) Diagnostics challenges and solutions. (3) Simulation / Evaluation problems. Some new approaches will be considered. Acknowledgements. This research has been

  5. e-Learning initiatives to support prescribing.

    Maxwell, Simon; Mucklow, John

    2012-10-01

    Preparing medical students to prescribe is a major challenge of undergraduate education. They must develop an understanding of clinical pharmacology and acquire knowledge about drugs and therapeutics, as well as the skills to prescribe for individual patients in the face of multiple variables. The task of delivering the learning required to achieve these attributes relies upon limited numbers of teachers, who have increasingly busy clinical commitments. There is evidence that training is currently insufficient to meet the demands of the workplace. e-Learning provides an opportunity to improve the learning experience. The advantages for teachers are improved distribution of learning content, ease of update, standardization and tracking of learner activities. The advantages for learners are ease of access, greater interactivity and individual choice concerning the pace and mix of learning. Important disadvantages are the considerable resource required to develop e-Learning projects and difficulties in simulating some aspects of the real world prescribing experience. Pre-requisites for developing an e-Learning programme to support prescribing include academic expertise, institutional support, learning technology services and an effective virtual learning environment. e-Learning content might range from complex interactive learning sessions through to static web pages with links. It is now possible to simulate and provide feedback on prescribing decisions and this will improve with advances in virtual reality. Other content might include a student formulary, self-assessment exercises (e.g. calculations), a glossary and an on-line library. There is some evidence for the effectiveness of e-Learning but better research is required into its potential impact on prescribing. © 2012 The Authors.

  12. Learning and Organizational Change in SPI Initiatives

    Science.gov (United States)

    Heikkilä, Marikka

    Explaining how organizations chance has been a central and enduring quest of management scholars and many other disciplines. In order to be successful change requires not only a new process or technology but also the engagement and participation of the people involved. In this vein the change process results in new behavior and is routinized in practical daily business life of the company. Change management provides a framework for managing the human side of these changes. In this article we present a literature review on the change management in the context of Software Process Improvement. The traditional view of learning, as a “lessons learned” or post-mortem reporting activity is often apparent in SPI literature. However, learning can also be viewed as a continuous change process where specific learning cycle starts with creative conflict and ends up in formal norms and systems. Since this perspective has almost no visibility in SPI literature of past it could show a new direction to the future development of change management in SPI.

  20. Eli Hecksher as a Portrait Maker

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available Eli Heckscher was not only author of extensive investigations into economic history. He was also skillful in depicting phenomena in small format in encyclopædias, journals and newspapers. This article presents Heckscher as portrait maker of economic scholars. In these portraits—what he emphasized, what he praised, what he criticized—one can discern the stance of the portrait maker himself. Overall, his portraits are permeated by admiration of sharp theoretical analyses and massive economic historical investigations. He admires the founding fathers of political economy, Adam Smith and David Ricardo, stresses continuity in the development of economic thought, praises humble innovators like David Davidson, Knut Wicksell and Alfred Marshall and denounces (what he perceives as pretentious innovators like Gustav Cassel and John Maynard Keynes. He is critical towards economists who attempt to break out of the classical and neoclassical tradition, especially representatives of the German historical school, and what he judges to be a new type of mercantilism, represented by Bertil Ohlin and Keynes. At the same time he appreciates voluminous and solid investigations into economic history, even if performed without theoretical beacons, by scholars like William Cunningham, William Ashley, John Clapham, Marc Bloch, Richard Ehrenberg and Werner Sombart.

    2013-11-01

    Neuroscience, in recent years, has started to look like a graveyard for drug development, with many large pharmaceutical companies either eliminating their brain disorder programs or cutting back heavily on such research. Novartis seemed to have made exactly this kind of drastic change two years ago when the company announced plans to shutter its neuroscience operations at its global headquarters in Basel, Switzerland. But the company made it known then that its intention was to ultimately set up a new neuroscience division at the company's US base in Cambridge, Massachusetts. The US site was initially picked to take advantage of the local academic strength in the field of psychiatric genetics. Now, it seems that Novartis is also looking to add stem cell technologies to the mix with the appointment in August of Ricardo Dolmetsch as the company's global head of neurosciences-the first new hire for the company's reincarnated division. As a professor at California's Stanford University School of Medicine for the past ten years, Dolmetsch made his name using induced pluripotent stem (iPS) cells to study a rare form of autism known as Timothy syndrome. Elie Dolgin met with Dolmetsch at the Novartis Institutes for BioMedical Research in the Technology Square area of Cambridge to discuss how he plans to succeed where so many others have failed.

    The world is on the verge of achieving global polio eradication. During >25 years of operations, the Global Polio Eradication Initiative (GPEI) has mobilized and trained millions of volunteers, social mobilizers, and health workers; accessed households untouched by other health initiatives; mapped and brought health interventions to chronically neglected and underserved communities; and established a standardized, real-time global surveillance and response capacity. It is important to document the lessons learned from polio eradication, especially because it is one of the largest ever global health initiatives. The health community has an obligation to ensure that these lessons and the knowledge generated are shared and contribute to real, sustained changes in our approach to global health. We have summarized what we believe are 10 leading lessons learned from the polio eradication initiative. We have the opportunity and obligation to build a better future by applying the lessons learned from GPEI and its infrastructure and unique functions to other global health priorities and initiatives. In so doing, we can extend the global public good gained by ending for all time one of the world's most devastating diseases by also ensuring that these investments provide public health dividends and benefits for years to come.

  6. Coming soon - Launch of e-learning initiative for supervisors

    CERN Multimedia

    2015-01-01

    In early July, the Learning and Development group is launching a new learning initiative specifically targeted at supervisors here at CERN. With the assistance of  experts on the subject, we have designed an exclusive series of five e-learning modules. These modules will help supervisors to synthesise some of the important processes that influence and impact their daily work and build key competencies as people managers.   Each module may take up to a maximum of 60 minutes to complete and covers the following topics: • CERN as an Organisation • People Management (Part 1) • People Management (Part 2) • Financial Management • Administrative Information Tools for Supervisors Supervisors will receive an invitation from the L&D group to access the modules on a dedicated e-learning space created on SharePoint. We recommend that all newly appointed supervisors access and complete the five modules within the first month of taking up their su...

    2014-04-01

    This study examined the very initial phases of orthographic and semantic acquisition in monolingual native English speakers learning Chinese words under controlled laboratory conditions. Participants engaged in 10 sessions of vocabulary learning, four of which were used to obtain ERPs. Performance in behavioral tests improved over sessions, and these data were used to define fast and slow learners. Most important is that ERPs in the two groups of learners revealed qualitatively distinct learning patterns. Only fast learners showed a left-lateralized increase in N170 amplitude with training. Furthermore, only fast learners showed an increased N400 amplitude with training, with a distinct anterior distribution. Slow learners, on the other hand, showed a posterior positive effect, with increasingly positive-going waveforms in occipital sites as training progressed. Possible mechanisms underlying these qualitative differences are discussed. Copyright © 2014 Society for Psychophysiological Research.

  11. Academics and Learners’ Perceptions on Blended Learning as a Strategic Initiative to Improve Student Learning Experience

    2017-01-01

    Full Text Available The increasingly tighter shift of socio-economic constraints on higher education sectors in the recent years has called for greater flexibilities in student learning experience both locally and abroad. To this end, we have recently implemented a Blended Learning Initiative in an attempt to provide better learning support and greater flexibility to our students. This initiative is also in line with the University’s aim of having 50% of our learning and teaching delivered on-line by 2020. In this report, we present our findings on academics and learners’ perceptions on the approach which were obtained through surveys. Results showed that blended learning approach was new to the academics and the factors for successful blended learning implementation were identified. Results also showed that learners appreciated the approach as it made learning more accessible and flexible. Furthermore, they also enjoyed the interesting online activities incorporated into their units. In addition, learners were also able to review and pace their own learning. They also perceived that they have the access to the resources and technical ability to cope with online learning materials and activities. Nonetheless, the survey also revealed that learners still prefer to have academics delivering information to them directly rather than a flipped classroom model. In conclusion, findings from this study provide insights that blended learning could be effective to supplement courses offered by the faculty.

    1990-01-01

    A description is given of a robot, possessing limited sensory and effectory capabilities but no initial model of the effects of its actions on the world, that acquires such a model through exploration, practice, and observation. By acquiring an increasingly correct model of its actions, it generates increasingly successful plans to achieve its goals. In an apparently nondeterministic world, achieving reliability requires the identification of reliable actions and a preference for using such actions. Furthermore, by selecting its training actions carefully, the robot can significantly improve its learning rate.

    SMILE is a Simple, Mental health, Initiative in Learning and Education. SMILE was a pilot project introduced into an undergraduate clinical nursing program, Southern Cross University, Australia 2010. The program aimed to improve the knowledge and skills of third-year nursing students participating in their first clinical placement in mental healthcare. Complementary to the clinical nursing program and the university curriculum, SMILE provided further training and support for student learning in mental healthcare. The SMILE project was a structured 15-day education program that covered the following topics: suicide prevention; psychosis; drugs and alcohol education; mental state exam; families and carers in mental health; and the Mental Health Act. The education sessions were one hour in duration. The educational material and resources were created from current research, literature and health service policy. A problem-based learning approach was used to support this education project. The dynamic factor related to SMILE was that it was based in the field. SMILE enabled the students to bridge a theory-practice gap and expand upon their current knowledge base as well as participate in ward activity. Twenty students attending their first clinical placement in mental healthcare participated in SMILE and were asked to complete a pre- and post- evaluation questionnaire before starting and upon completion of the 15-day project. The students participating in SMILE reported a greater understanding of mental healthcare issues and expressed a developing knowledge base and improved practical skill level. SMILE was a positive initiative that provided valuable feedback and opportunity to improve on clinical education in mental healthcare.

    ELI-Beamlines is one of the pillars of the pan-European project ELI (Extreme Light Infrastructure). It will be an ultra high-intensity, high repetition-rate, femtosecond laser facility whose main goal is generation and applications of high-brightness X-ray sources and accelerated charged particles in different fields. Particular care will be devoted to the potential applicability of laser-driven ion beams for medical treatments of tumors. Indeed, such kind of beams show very interesting peculiarities and, moreover, laser-driven based accelerators can really represent a competitive alternative to conventional machines since they are expected to be more compact in size and less expensive. The ELIMED project was launched thanks to a collaboration established between FZU-ASCR (ELI-Beamlines) and INFN-LNS researchers. Several European institutes have already shown a great interest in the project aiming to explore the possibility to use laser-driven ion (mostly proton) beams for several applications with a particular regard for medical ones. To reach the project goal several tasks need to be fulfilled, starting from the optimization of laser-target interaction to dosimetric studies at the irradiation point at the end of a proper designed transport beam-line. Researchers from LNS have already developed and successfully tested a high-dispersive power Thomson Parabola Spectrometer, which is the first prototype of a more performing device to be used within the ELIMED project. Also a Magnetic Selection System able to produce a small pencil beam out of a wide energy distribution of ions produced in laser-target interaction has been realized and some preliminary work for its testing and characterization is in progress. In this contribution the status of the project will be reported together with a short description of the of the features of device recently developed.

    2016-11-01

    This paper features two studies confirming a lasting impact of first learning on how subsequent experience is weighted in early relevance-filtering processes. In both studies participants were exposed to sequences of sound that contained a regular pattern on two different timescales. Regular patterning in sound is readily detected by the auditory system and used to form "prediction models" that define the most likely properties of sound to be encountered in a given context. The presence and strength of these prediction models is inferred from changes in automatically elicited components of auditory evoked potentials. Both studies employed sound sequences that contained both a local and longer-term pattern. The local pattern was defined by a regular repeating pure tone occasionally interrupted by a rare deviating tone (p=0.125) that was physically different (a 30msvs. 60ms duration difference in one condition and a 1000Hz vs. 1500Hz frequency difference in the other). The longer-term pattern was defined by the rate at which the two tones alternated probabilities (i.e., the tone that was first rare became common and the tone that was first common became rare). There was no task related to the tones and participants were asked to ignore them while focussing attention on a movie with subtitles. Auditory-evoked potentials revealed long lasting modulatory influences based on whether the tone was initially encountered as rare and unpredictable or common and predictable. The results are interpreted as evidence that probability (or indeed predictability) assigns a differential information-value to the two tones that in turn affects the extent to which prediction models are updated and imposed. These effects are exposed for both common and rare occurrences of the tones. The studies contribute to a body of work that reveals that probabilistic information is not faithfully represented in these early evoked potentials and instead exposes that predictability (or conversely

    Curation is traditionally defined as the process of collecting and organizing information around a common subject matter or a topic of interest and typically occurs in museums, art galleries, and libraries. The task of organizing data around specific topics or themes is a vibrant and growing effort in the biological sciences but to date this effort has not been actively pursued in the Earth sciences. This presentation will introduce the concept of geocuration, which we define it as the act of searching, selecting, and synthesizing Earth science data/metadata and information from across disciplines and repositories into a single, cohesive, and useful compendium. We also present the Climate Data Initiative (CDI) project as an prototypical example. The CDI project is a systematic effort to manually curate and share openly available climate data from various federal agencies. CDI is a broad multi-agency effort of the U.S. government and seeks to leverage the extensive existing federal climate-relevant data to stimulate innovation and private-sector entrepreneurship to support national climate change preparedness. The geocuration process used in the CDI project, key lessons learned, and suggestions to improve similar geocuration efforts in the future will be part of this presentation.

    Fasso, Alberto; Korn, Georg; Versaci, Roberto; Ferrari, Anna

    2015-01-01

    ELI-beamlines is one of the four pillars of the Extreme Light Infrastructure, a European ESFRI Project, for the next generation of high-energy and high-intensity lasers. It aims at the development of high-brightness sources of X-rays and the acceleration of proton, electron, and ion beams, to be used both for pure research and practical applications. Aiming at a proper radiation protection assessment, for both shielding and activation, extensive FLUKA simulations have been performed, taking into account the laser high repetition rates. The present work, which is the continuation of the calculations presented at SATIF-10, is the first one based on the design of the facility being constructed and on the updated experimental set-up.

  11. Laser-driven acceleration at ELI Beamlines - radioprotection aspects

    International Nuclear Information System (INIS)

    Olsovcova, V.; Fasso, A; Versaci, R.

    2014-01-01

    The international research centre ELI Beamlines, which is under construction in the village of Dolni Brezany near Prague, will exploit high power lasers of PW class to generate and accelerate beams of charged particles (up to tens of GeVs in energy). The beams will be used for both fundamental and applied research by experts from various scientific fields, including biology, medicine, plasma physics but also dosimetry and radiation protection. As laboratories operating lasers do not belong among the traditional 'radiation workplaces', there are no suitable specialized recommendations or standards available. Therefore, it is necessary to newly implement the existing general recommendations. Further, the generated mixed fields possess unique properties due to their production methods. As a result, the routinely used detection methods are not reliable or fail completely. (authors)

    The major research equipment of the Attosecond Light Pulse Source of the Extreme Light Infrastructure (ELI-ALPS) are driven by laser pulses of few cycle duration operating in the 100 W average power regime. The peak power and the repetition rate span from 1 TW at 100 kHz up to PW at 10 Hz. The systems are designed for stable and reliable operation, yet to deliver pulses with unique parameters, especially with unmatched fluxes and extreme bandwidths. This exceptional performance will enable the generation of secondary sources with exceptional characteristics, including light sources ranging from the THz to the X-ray spectral ranges, and particle sources. The experimental activities in the building complex to be inaugurated early 2017 will start with the installation of the two 100 kHz repetition rate, CEP stabilized lasers in May 2017. The MIR laser produces 0.15mJ, shorter than 4-optical-cylce pulses tunable between 2.5-3.9 µm. The first stage of the HR laser will provide pulses around 1 µm with 1 mJ energy and pulse duration less than 6.2 fs. The systems will be optically synchronized to each other with a temporal jitter below 1 fs. Along with the installation of the lasers, we will also start the assembly of the high harmonic beamlines and the THz laboratory, as well as nanoplasmonic experiments. The XUV bursts of light with attosecond duration are expected to be generated by the end of 2017.

  1. Elie Cartan and pan-geometry of multispatial hyperspace

    International Nuclear Information System (INIS)

    Czajko, Jakub

    2004-01-01

    Elie Cartan has proved that highest dimensionality of any simple geometric space is three and that an exterior differentiation of a 3D+ geometric object gives bivector, which may correspond to some two 2D surfaces as if the 3D+ geometric object comprised two 3D objects. Since one cannot increase the dimensionality of a 3D space even though more than four independently varying physical magnitudes do exist, then an expansion of dimensionality requires a multispatial hyperspace that contains many simple geometric 3D spaces. Presence of such a hyperspace prompts for an entirely new concept of vectors with an isometric operation of vector multiplication of traditional vectors (3-tuples). This new operation on 3-vectors implies presence of a 3D mass-based linear vector space and consequently thus a 9D geometric hyperspace for classical mechanics alone. Also an outline of entirely new, synthetic approach to physics and mathematics is introduced. This synthetic approach can be used to design a computer-aided knowledge extracting system, which could generate entirely new scientific knowledge

  14. Eli Lilly and Company's bioethics framework for human biomedical research.

    Van Campen, Luann E; Therasse, Donald G; Klopfenstein, Mitchell; Levine, Robert J

    2015-11-01

    Current ethics and good clinical practice guidelines address various aspects of pharmaceutical research and development, but do not comprehensively address the bioethical responsibilities of sponsors. To fill this void, in 2010 Eli Lilly and Company developed and implemented a Bioethics Framework for Human Biomedical Research to guide ethical decisions. (See our companion article that describes how the framework was developed and implemented and provides a critique of its usefulness and limitations.) This paper presents the actual framework that serves as a company resource for employee education and bioethics deliberations. The framework consists of four basic ethical principles and 13 essential elements for ethical human biomedical research and resides within the context of our company's mission, vision and values. For each component of the framework, we provide a high-level overview followed by a detailed description with cross-references to relevant well regarded guidance documents. The principles and guidance described should be familiar to those acquainted with research ethics. Therefore the novelty of the framework lies not in the foundational concepts presented as much as the attempt to specify and compile a sponsor's bioethical responsibilities to multiple stakeholders into one resource. When such a framework is employed, it can serve as a bioethical foundation to inform decisions and actions throughout clinical planning, trial design, study implementation and closeout, as well as to inform company positions on bioethical issues. The framework is, therefore, a useful tool for translating ethical aspirations into action - to help ensure pharmaceutical human biomedical research is conducted in a manner that aligns with consensus ethics principles, as well as a sponsor's core values.

  18. Mayan Children's Creation of Learning Ecologies by Initiative and Cooperative Action.

    2015-01-01

    This chapter examines Mayan children's initiatives in creating their own learning environments in collaboration with others as they engage in culturally relevant endeavors of family and community life. To this end, I carry out a fine-grained ethnographic and linguistic analysis of the interactional emergence of learning ecologies. Erickson defines learning ecology as a socioecological system where participants mutually influence one another through verbal and nonverbal actions, as well as through other forms of semiotic communication (2010, 254). In analyzing learning ecologies, I adopt a "theory of action" approach, taking into account multimodal communication (e.g., talk, gesture, gaze, body positioning), participants' sociospatial organization, embodied action, objects, tools, and other culturally relevant materials brought together to build action (Goodwin, 2000, 2013; Hutchins, 1995). I use microethnographic analysis (Erickson, 1992) to bring to the surface central aspects of children's agentive roles in learning through "cooperative actions" (Goodwin, 2013) and "hands-on" experience (Ingold, 2007) the skills of competent members of their community. I examine three distinct Learning Ecologies created by children's initiatives among the Mayan children that I observed: (i) children requesting guidance to collaborate in a task, (ii) older children working on their own initiative with subsequent monitoring and correction from competent members, and (iii) children with near competence in a task with occasional monitoring and no guidance. I argue that these findings enrich and add power to models of family- and community-based learning such as Learning by Observing and Pitching In (Rogoff, 2014). © 2015 Elsevier Inc.

    People with learning disabilities are often marginalised in healthcare, including in hospice settings, and as a result may not receive effective end of life care. Research in hospice settings has identified that many staff lack confidence, skills and knowledge in caring for people with learning disabilities, which can have a negative effect on the care these individuals receive. To address these issues, the author has proposed a service improvement initiative, which she developed as part of her learning disability nursing degree programme. This proposed initiative aimed to enhance end of life care for people with learning disabilities through the implementation of a community learning disability link nurse in the hospice setting. ©2018 RCN Publishing Company Ltd.

    Full Text Available Distance learning is expanding and replacing the traditional academic medical settings. Managing trauma patients seems to be a prerequisite skill for medical students. This study has been done to evaluate the efficiency of distance learning on performing the initial assessment and management in trauma patients, compared with the traditional learning among senior medical students. One hundred and twenty senior medical students enrolled in this single-blind quasi-experimental study and were equally divided into the experimental (distance learning and control group (traditional learning. All participants did a written MCQ before the study. The control group attended a workshop with a 50-minute lecture on initial management of trauma patients and a case simulation scenario followed by a hands-on session. On the other hand, the experimental group was given a DVD with a similar 50-minute lecture and a case simulation scenario, and they also attended a hands-on session to practice the skills. Both groups were evaluated by a trauma station in an objective structured clinical examination (OSCE after a month. The performance in the experimental group was statistically better (P=0.001 in OSCE. Distance learning seems to be an appropriate adjunct to traditional learning.

  3. The elicitin-like glycoprotein, ELI025, is secreted by the pathogenic oomycete Pythium insidiosum and evades host antibody responses.

    Directory of Open Access Journals (Sweden)

    Tassanee Lerksuthirat

    Full Text Available Pythium insidiosum is a unique oomycete that can infect humans and animals. Patients with a P. insidiosum infection (pythiosis have high rates of morbidity and mortality. The pathogen resists conventional antifungal drugs. Information on the biology and pathogenesis of P. insidiosum is limited. Many pathogens secrete proteins, known as effectors, which can affect the host response and promote the infection process. Elicitins are secretory proteins and are found only in the oomycetes, primarily in Phytophthora and Pythium species. In plant-pathogenic oomycetes, elicitins function as pathogen-associated molecular pattern molecules, sterol carriers, and plant defense stimulators. Recently, we reported a number of elicitin-encoding genes from the P. insidiosum transcriptome. The function of elicitins during human infections is unknown. One of the P. insidiosum elicitin-encoding genes, ELI025, is highly expressed and up-regulated at body temperature. This study aims to characterize the biochemical, immunological, and genetic properties of the elicitin protein, ELI025. A 12.4-kDa recombinant ELI025 protein (rELI025 was expressed in Escherichia coli. Rabbit anti-rELI025 antibodies reacted strongly with the native ELI025 in P. insidiosum's culture medium. The detected ELI025 had two isoforms: glycosylated and non-glycosylated. ELI025 was not immunoreactive with sera from pythiosis patients. The region near the transcriptional start site of ELI025 contained conserved oomycete core promoter elements. In conclusion, ELI025 is a small, abundant, secreted glycoprotein that evades host antibody responses. ELI025 is a promising candidate for development of diagnostic and therapeutic targets for pythiosis.

    Yehezkel, Oren; Sterkin, Anna; Lev, Maria; Levi, Dennis M; Polat, Uri

    2016-04-28

    The goal of the present study was to evaluate the dependence of perceptual learning gains on initial visual acuity (VA), in a large sample of subjects with a wide range of VAs. A large sample of normally sighted and presbyopic subjects (N = 119; aged 40 to 63) with a wide range of uncorrected near visual acuities (VA, -0.12 to 0.8 LogMAR), underwent perceptual learning. Training consisted of detecting briefly presented Gabor stimuli under spatial and temporal masking conditions. Consistent with previous findings, perceptual learning induced a significant improvement in near VA and reading speed under conditions of limited exposure duration. Our results show that the improvements in VA and reading speed observed following perceptual learning are closely linked to the initial VA, with only a minor fraction of the observed improvement that may be attributed to the additional sessions performed by those with the worse VA.

    ELISSA is an array of silicon strip detectors under construction at the ELI-NP facility for measurements of photodissociation reactions using high-brilliance, quasi monoenergetic gamma beams. The detection system consists of 35 single-sided position-sensitive X3 detectors arranged in a cylindrical configuration and eight QQQ3 detectors as end-caps. A batch of forty X3 detectors have been tested at ELI-NP. The energy and position resolution, ballistic deficit, leakage currents, and depletion voltage were measured and analyzed. Measurements of the energy resolution were carried out using two read-out electronic chains, one based on multichannel preamplifiers and another based on multiplexers.

    Full Text Available The research in question investigates the technologies of initiating independent activity within the framework of distance learning and their psychological aspects. The authors’ classification of educational technologies of initiating students into independent cognitive activity is presented. Such technologies utilize various psychological mechanisms of exciting students’ cognitive interest, intensifying cognitive processes, developing independent activity skills, and, as a result, increase motivation for independent activity and learning on the whole. These include such types of technologies as developmental technologies, interactive technologies, technologies of information transfer, technologies of meaning-making initiation. The research of the attitude of distance learning educators to independent activity of students and the content of the academic courses were done at Moodle-based education programs. The findings show the differences in retention rate among distance learning educators whose competence in terms of initiating students into independent (self-guided activity varies. It’s emphasized that interactive lectures, videoconferences, audio-visual aids, interactive seminars, glossaries, interactive tests are considered the most efficient technologies in initiating students into independent (self-guided activity. The obtained results have made it possible to stress the developmental effect of distance learning technologies and the technologies of initiating students into independent (self-guided activity in various psychic spheres of students: cognitive, individual, emotional. We mention the changes in motivational sphere of students and their meaning-making activity. In the course of correct development of distance learning we notice the development of voluntary and nonvoluntary cognitive activity. A student starts actively participating in educational process, he becomes the creator of his own world.

    Full Text Available Global environmental change will have major impacts on ecosystems and human livelihoods while challenging the adaptive capacity of individuals and communities. Social learning, an ongoing adaptive process of knowledge generation, reflection and synthesis, may enhance people’s awareness about climate change and its impacts, with positive outcomes for their adaptive capacity. The objectives of this study were to assess the prevalence of factors promoting social learning in climate change adaptation initiatives in South Africa. An online survey was used to obtain the views of decision makers in government and non-governmental organisations about the presence of personal factors and organisational factors that promote social learning. Descriptive analysis was used to assess these issues. The findings provide some evidence of social learning in climate change adaptation projects in South Africa, with the majority of respondents indicating that personal social learning indicators were present. Mechanisms for improved conflict resolution were, however, less prevalent. The organisational and governance-related barriers to implementation also presented significant challenges. Some of the main organisational barriers were short timeframes for implementing projects, inadequate financial resources, political interference, shortcomings in governance systems and lack of knowledge and expertise in organisations. There is a need for organisations to promote social learning by ensuring that their organisational environment and governance structures are conducive for their employees to embrace social learning. This will help contribute to the overall success of climate change adaptation initiatives.

  13. Toward an Integrative Perspective on Social Learning in System Innovation Initiatives

    2016-03-01

    Full Text Available Sustainability transitions go hand in hand with learning. Theories in the realm of sustainability sciences mostly concentrate on diversity and learning outcomes, whereas theories from the educational sciences mostly focus on learning as an interactive process. In this contribution, we aim to benefit from an integration of these perspectives in order to better understand how different interaction patterns contribute to learning. We studied STAP, an innovation initiative of Dutch greenhouse growers. The Dutch greenhouse sector is predominantly focused on production and efficiency, which causes problems for its future viability. STAP aimed to make the sector more market-oriented while at the same time increasing its societal acceptability (societally responsible innovation. To that end, STAP focused on the development of integrated value chains (primary production, sales, trade that can contribute to a transition towards a societally sensitive greenhouse sector. As action researchers, we collected extensive transcripts of meetings, interviews, and various other documents. We used an open coding strategy to identify different patterns of interaction and the learning outcomes produced by the initiative. We then linked the interaction patterns to the outcomes. Analysis suggests that seemingly negative attack-and-defend patterns of interaction certainly can result in substantial learning results, while seemingly positive synthetic interaction patterns, where participants strive to build on each other, can result in rather bland interaction without substantial outcomes. The results offer an empirical basis to our approach of linking learning interactions to learning outcomes, and it suggests that learning for sustainability can be enhanced by focusing on interaction patterns.

  2. Measures of student success with textbook transformations: the Affordable Learning Georgia Initiative

    Directory of Open Access Journals (Sweden)

    Emily Croteau

    2017-03-01

    Full Text Available In 2014, the state of Georgia’s budget supported a University System of Georgia (USG initiative: Affordable Learning Georgia (ALG. The initiative was implemented via Textbook Transformation Grants, which provided grants to USG faculty, libraries and librarians, and institutions to “transform their use of textbooks and other learning materials into using lower cost options”, in other words to use open educational resources (OER in lieu of a traditional bound textbook. The Round One Textbook Transformation Grants have already shown to be successful in that they saved students approximately $760,000.  What is not known, is the collective impact on student learning. This study examines the learning gains or losses pre- and post-transformation in ALG Round One courses where traditional resources were replaced with OER.  It estimates differences between pre- and post- textbook transformation across the following outcomes: 1 Drop Fail Withdraw (DFW rates, 2 rates of completion, 3 numbers of students receiving a final grade of A or B, C and D, 4 numerical final grades as a percent, 5 final exam grades as a percent, and, 6 course-specific assessment grades measured in percent. Twenty-four data sets were analyzed for DFW rate, eight data sets for completion rate, fourteen data sets for grade distribution, three data sets for final exam grades, three data sets for course specific assessment and one data set for final grades. The null hypothesis that there would be no differences between pre- and post-transformation rates in these learning outcomes was supported.  Thus, this study demonstrates that the USG’s ALG initiative helped students save money without negatively impacting learning outcomes. In addition, it is the first of its kind to measure some of these learning outcomes (e.g. final exam grade, assessment grade, and distribution of letter grades at this scale.

  3. BUILDING HUMAN CAPITAL: THE IMPACT OF PARENTS´ INITIAL EDUCATIONAL LEVEL AND LIFELONG LEARNING ON THEIR CHILDREN

    Directory of Open Access Journals (Sweden)

    FISCHER, Jakub

    2013-12-01

    Full Text Available The aim of this paper is to examine the impact of parents´ educational level on lifelong learning of children and relationship between parents´ and student´ lifelong learning including language skills and computer literacy. This intergenerational transmission, if proven, could influence the investments into the human capital in the long run. We used data from Adult Education Survey 2011 (AES to test the hypothesis that the parental attained level of education has a significant impact on the initial educational level of their children as well as on their lifelong learning participation. Furthermore, using data from AES, we tested the association between parental educational level and children´s language skills and reading activity and between parental non-formal as well as informal education and students´ lifelong learning. We have found that the parental effect on lifelong learning participation is slightly weaker than the effect of initial adult´s education. Nevertheless, the intergenerational transmission mechanism obviously works. The relationship between parental and students computer literacy is statistically significant, nevertheless weak. As for the nominal and ordinal character of the data, we used mainly the standard statistical methods including nonparametric tests, logit model and correspondence analysis.

  4. Initial Writing Learning from a Socio-Cultural Perspective: A Learning Experience on the Research Field

    María Ivoneth Lozano Rodríguez

    2017-07-01

    Full Text Available In this article, the fundamentals of the training process of researchers on the Master in Pedagogy of the Mother Tongue context are explained. The reflection is oriented from projects that are developed in the first writing cycle. It presents the accompaniment process in the disciplinary, pedagogical, didactic and investigative field, starting from the teaching of writing problem in the first education. It starts from recognizing prescriptive and normative practices of language teaching in which writing is unknown as a social activity and the evolutionary process is not taken into account, nor a scaffolding that enhances what children already know favors their appropriation from social interaction and the granting of differentiated aid. In the same way, the article shows how, from the action research, transformative didactic proposals are being constructed, within the pedagogy by projects framework. That seek to correspond with the fundamentals of an interaction and sociocultural theory of learning and with a socio-discursive perspective of the acquisition of writing in which it is recognized as a fundamentally social, intentional, situated activity and its learning is constructed in interaction processes.

    In many countries, undergraduates are required to take at least one introductory computer course to enhance their computer literacy and computing skills. However, the application software education in Taiwan can hardly be deemed as effective in developing students' practical computing skills. The author applied online self-regulated learning (SRL) and collaborative learning (CL) with initiation in a blended computing course and examined the effects of different combinations on enhancing students' computing skills. Four classes, comprising 221 students, participated in this study. The online SRL and CL with initiation (G1, n = 53), online CL with initiation (G2, n = 68), and online CL without initiation (G3, n = 68) were experimental groups, and the last class, receiving traditional lecture (G4, n = 32), was the control group. The results of this study show that students who received the intervention of online SRL and CL with initiation attained significantly best grades for practical computing skills, whereas those that received the traditional lectures had statistically poorest grades among the four classes. The implications for schools and educators who plan to provide online or blended learning for their students, particularly in computing courses, are also provided in this study.

    The Eli Lilly Pharmaceutical Company of Indianapolis, Indiana distributed some 150,000 copies of the third edition of Sir William Osler's Aequanimitas to graduating medical students between 1932 and 1953. Bibliophiles have considered these volumes identical. However, there were at least seven different printings in English and one in Spanish and one in Portuguese. The size of the book and type of paper changed over the years. The title page, spine information, and printing information also changed. A congratulatory letter from Eli Lilly and Company was placed in the front of each book. These letters have many differences. Thus, the volumes are not identical and the recognition of these differences opens a new field for research and collecting.

    Position-sensitive silicon strip detectors represent one of the best solutions for the detection of charged particles as they provide good energy and position resolution over a large range of energies. A silicon array coupled with the gamma beams at the ELI-NP facility would allow measuring photodissociation reactions of interest for Big Bang Nucleosynthesis and on heavy nuclei intervening in the p-process. Forty X3 detectors for our ELISSA (ELI-NP Silicon Strip Detectors Array) project have been recently purchased and tested. We investigated several specifications, such as leakage currents, depletion voltage, and detector stability under vacuum. The energy and position resolution, and ballistic deficit were measured and analyzed. This paper presents the main results of our extensive testing. The measured energy resolution for the X3 detectors is better than results published for similar arrays (ANASEN or ORRUBA).

    Full Text Available Fostering Responsible Research and Innovation (RRI is the next big step in the methodological teaching of Science. This is the solution towards an open classroom and innovation system of learning. The school science teaching needs to become more engaging. Science education should be an essential component of a learning continuum not only in classroom, but also for all, from pre- school to active engaged citizenship. "The Learning Science Through Theatre" Initiative creates a network of knowledge and collaboration between different communities by learning about science through other disciplines and learning about other disciplines through science. Forty Three (43 theatrical performances during the school years 2014-2016 were organized by secondary school students (2000 subjects which embed both scientific concepts and cultural/ social elements which are expressed by embodied, verbal interaction and analogies. The methodology constitutes a merging of qualitative, quantitative and grounded theory analysis. The data were classified into categories and they were cross- checked by registrations forms, filled by the teachers. Results show that the acquisition of knowledge is successful with the co- existence of multiple semiotic systems and the theatrical performances are compatible with the principles of RRI.

    The huge progress made in the laser driven ion acceleration had open the possibility of using ions generated in high power laser interactions with solid targets for the production of medical isotopes. Indeed, lasers could provide several key features with respect to the traditional method where the target activation is produced by particle beams delivered by cyclotrons. The price and the dimensions of high power lasers are on a descendant slope and the quality of the produced ion beams is continuously increasing. However, in order to compete with cyclotrons, the average proton current intensity has to be increased for example by increasing the frequency of the laser pulses. In our contribution, we review the general ideas of the laser-based radioisotope production and we present our analysis on the potential of the medical isotope generation at ELI-NP with a focus on 18F. We use estimations of the proton beam parameters and a code implemented in Geant4 for computing the yield of the main production channel taking into account the experimental conditions available soon at ELI-NP. The obtained results are compatible with previous studies and will be verified by experiments foreseen at the future ELI-NP facility, under construction now in Magurele, Romania.

    2016-01-01

    ELisA is a web tool used by the ATLAS community as a daily logbook facility in order to record and share information concerning the experiment's operation and deployment. A few subsystems, notably the FTK subsystem, of the ATLAS experiment would like to setup a logbook based on the ELisA logbook for their own private usage. This new logbook would be completely separated from the main ATLAS logbook and will only be accessed from the general public network. In this project the implementation and setup of the ELisA based logbook will be discussed as well as various modifications that were made to the new logbook. These modifications were specified by the FTK users in order to make the logbook relevant to the FTK subsystem. Once the logbook was functioning as expected and the users were satisfied with the modifications, the FTK logbook was installed on a FTK dedicated machine where it is currently being used by members of the FTK group.

    The Extreme Light Infrastructure-Nuclear Physics (ELI-NP) facility, under construction in Magurele near Bucharest in Romania, will provide high-intensity and high-resolution gamma ray beams that can be used to address hotly debated problems in nuclear astrophysics, such as the accurate measurements of the cross sections of the 24Mg(γ,α)20Ne reaction, that is fundamental to determine the effective rate of 28Si destruction right before the core collapse and the subsequent supernova explosion. For this purpose, a silicon strip detector array (named ELISSA, acronym for Extreme Light Infrastructure Silicon Strip Array) will be realized in a common effort by ELI-NP and Laboratori Nazionali del Sud (INFN-LNS), in order to measure excitation functions and angular distributions over a wide energy and angular range. A prototype of ELISSA was built and tested at INFN-LNS in Catania (Italy) with the support of ELI-NP. In this occasion, we have carried out experiments with alpha sources and with a 11 MeV 7Li beam. Thanks to our approach, the first results of those tests show up a very good energy resolution (better than 1%) and very good position resolution, of the order of 1 mm. Moreover, a threshold of 150 keV can be easily achieved with no cooling.

    At the moment, the new European research facility called ELI-NP (The Extreme Light Infrastructure - Nuclear Physics) is being built in Bucharest-Magurele, Romania. It is one of three parts of the ELI project and offers applications for the investigation of questions concerning nuclear physics. The 8 HPGe (High-Purity Germanium) CLOVER detectors of ELIADE (ELI-NP Array of DEtectors) with four crystals each and high resolution are important components for the gamma spectroscopic study of photonuclear reactions. These detectors are surrounded by standard anti-Compton shields (AC shield). We investigate the possibility to operate for two of the ELIADE CLOVERS an advanced version of an AC shield as escape γ-rays pair spectrometers to extend the high-resolution spectroscopy to photon energies of several MeV where the pair production process dominates. The main tasks in this work are to develop and test such an AC shield: a pair spectrometer with BGO and CsI(Tl) crystals with APD (avalanche photodiode) or SPM (silicon photomultiplier) readout. The results of prototype testing are reported.

    2003-01-01

    Family caregivers of older adults with progressive dementia (e.g., Alzheimer's disease) are faced with a variety of emotional and behavioral difficulties, such as dealing with persistent, repetitive questions, managing agitation and depression, and monitoring hygiene and self-care activities. Although professional and governmental organizations have called for the creation of community-based education and support programs, most dementia caregivers continue to receive little or no formal instruction in responding effectively to these challenges. The current paper describes the development and implementation of Alzheimer's Caregiver Support Online, a Web- and telephone-based education and support network for caregivers of individuals with progressive dementia. Lessons learned from the first two years of this state-supported initiative are discussed, followed by the findings of a Robert Wood Johnson Foundation-funded strategic marketing initiative and an initial program evaluation of AlzOnline's Positive Caregiving classes. Finally, clinical implications and future directions for program development and evaluation research are proposed.

    The world is closer than ever to achieving global polio eradication, with record-low polio cases in 2015 and the impending prospect of a polio-free Africa. Tens of millions of volunteers, social mobilizers, and health workers have participated in the Global Polio Eradication Initiative. The program contributes to efforts to deliver other health benefits, including health systems strengthening. As the initiative nears completion after more than twenty-five years, it becomes critical to document and transition the knowledge, lessons learned, assets, and infrastructure accumulated by the initiative to address other health goals and priorities. The primary goals of this process, known as polio legacy transition planning, are both to protect a polio-free world and to ensure that investments in polio eradication will contribute to other health goals after polio is completely eradicated. The initiative is engaged in an extensive transition process of consultations and planning at the global, regional, and country levels. A successful completion of this process will result in a well-planned and -managed conclusion of the initiative that will secure the global public good gained by ending one of the world's most devastating diseases and ensure that these investments provide public health benefits for years to come.

    This case report describes the phases of an Amish Burn Care Project and the lessons learned throughout the process. Data sources to construct the case report included participant observation, interviews, archival documents, and a focus group. The narrative is organized into five phases of a participatory research approach: engagement, formalization, mobilization, maintenance, and expansion. Community-initiated research led to legitimate change, working together for change took time, team members grew in mutual trust and respect for each other, cultural humility brought personal and professional growth, and capacity building took place through mutually supported efforts.

    (Background and Objective): The occurrence of hard exudates is one of the early signs of diabetic retinopathy which is one of the leading causes of the blindness. Many patients with diabetic retinopathy lose their vision because of the late detection of the disease. Thus, this paper is to propose a novel method of hard exudates segmentation in retinal images in an automatic way. (Methods): The existing methods are based on either supervised or unsupervised learning techniques. In addition, the learned segmentation models may often cause miss-detection and/or fault-detection of hard exudates, due to the lack of rich characteristics, the intra-variations, and the similarity with other components in the retinal image. Thus, in this paper, the supervised learning based on the multilayer perceptron (MLP) is only used to identify initial seeds with high confidences to be hard exudates. Then, the segmentation is finalized by unsupervised learning based on the iterative graph cut (GC) using clusters of initial seeds. Also, in order to reduce color intra-variations of hard exudates in different retinal images, the color transfer (CT) is applied to normalize their color information, in the pre-processing step. (Results): The experiments and comparisons with the other existing methods are based on the two well-known datasets, e_ophtha EX and DIARETDB1. It can be seen that the proposed method outperforms the other existing methods in the literature, with the sensitivity in the pixel-level of 0.891 for the DIARETDB1 dataset and 0.564 for the e_ophtha EX dataset. The cross datasets validation where the training process is performed on one dataset and the testing process is performed on another dataset is also evaluated in this paper, in order to illustrate the robustness of the proposed method. (Conclusions): This newly proposed method integrates the supervised learning and unsupervised learning based techniques. It achieves the improved performance, when compared with the

    This article addresses criticisms of qualitative research for spawning studies that lack analytic development and theoretical import. It focuses on teaching initial grounded theory tools while interviewing, coding, and writing memos for the purpose of scaling up the analytic level of students' research and advancing theory construction. Adopting these tools can improve teaching qualitative methods at all levels although doctoral education is emphasized here. What teachers cover in qualitative methods courses matters. The pedagogy presented here requires a supportive environment and relies on demonstration, collective participation, measured tasks, progressive analytic complexity, and accountability. Lessons learned from using initial grounded theory tools are exemplified in a doctoral student's coding and memo-writing excerpts that demonstrate progressive analytic development. The conclusion calls for increasing the number and depth of qualitative methods courses and for creating a cadre of expert qualitative methodologists. © The Author(s) 2015.

    Quantification of tissue properties with photoacoustic (PA) imaging typically requires a highly accurate representation of the initial pressure distribution in tissue. Almost all PA scanners reconstruct the PA image only from a partial scan of the emitted sound waves. Especially handheld devices, which have become increasingly popular due to their versatility and ease of use, only provide limited view data because of their geometry. Owing to such limitations in hardware as well as to the acoustic attenuation in tissue, state-of-the-art reconstruction methods deliver only approximations of the initial pressure distribution. To overcome the limited view problem, we present a machine learning-based approach to the reconstruction of initial pressure from limited view PA data. Our method involves a fully convolutional deep neural network based on a U-Net-like architecture with pixel-wise regression loss on the acquired PA images. It is trained and validated on in silico data generated with Monte Carlo simulations. In an initial study we found an increase in accuracy over the state-of-the-art when reconstructing simulated linear-array scans of blood vessels.

    In this work, we present the design, implementation, and initial outcomes of the Climate Academy, a hybrid professional development program delivered through a combination of face-to-face and online interactions, intended to prepare formal and informal science teachers (grades 5-16) in teaching about climate change. The Climate Academy was designed around core elements of successful environmental professional development programs and aligned with practices advocated in benchmarked science standards. Data were collected from multiple sources including observations of professional development events, participants' reflections on their learning, and collection of instructional units designed during the Academy. Data were also collected from a focal case study teacher in a middle school setting. Case study data included classroom observations, teacher interviews, and student beliefs toward climate change. Results indicated that the Climate Academy fostered increased learning among participants of both climate science content and pedagogical strategies for teaching about climate change. Additionally, results indicated that participants applied their new learning in the design of climate change instructional units. Finally, results from the case study indicated positive impacts on student beliefs and greater awareness about climate change. Results have implications for the design of professional development programs on climate change, a topic included for the first time in national standards.

    Along with the development of petawatt class laser systems, the interaction between high power lasers and matter flourished an extensive research, with high-interest applications like: laser nuclear physics, proton radiography or cancer therapy. The new ELI-NP (Extreme Light Infrastructure - Nuclear Physics) petawatt laser facility, with 10PW and ~ 1023W/cm2 beam intensity, is one of the innovative projects that will provide novel research of fundamental processes during light-matter interaction. As part of the ELI-NP facility, Targets Laboratory will provide the means for in-house manufacturing and characterization of the required targets (mainly solid ones) for the experiments, in addition to the research activity carried out in order to develop novel target designs with improved performances. A description of the Targets Laboratory with the main pieces of equipment and their specifications are presented. Moreover, in view of the latest progress in the target design, one of the proposed strategies for the forthcoming experiments at ELI-NP is also described, namely: ultra-thin patterned foil of diamond-like carbon (DLC) coated with a carbon-based ultra-low density layer. The carbon foam which behaves as a near-critical density plasma, will allow the controlled-shaping of the laser pulse before the main interaction with the solid foil. Particular emphasis will be directed towards the target's design optimization, by simulation tests and tuning the key-properties (thickness/length, spacing, density foam, depth, periodicity etc.) which are expected to have a crucial effect on the laser-matter interaction process.

    The ELI-NP facility will focus a 10 PW pulsed laser beam at intensities of ∼10{sup 23} W/cm{sup 2} for the first time, enabling investigation of the new physical phenomena at the interfaces of plasma, nuclear and particle physics. The electric field in the laser focus has a maximum value of ∼10{sup 15} V/m at such laser intensities. In the ELI-NP Experimental Area E6, we propose the study of Radiation Reaction, Strong Field Quantum Electrodynamics (QED) effects and resulting production of Ultra-bright Sources of Gamma-rays which could be used for nuclear activation. Two powerful, synchronized 10 PW laser beams will be focused in the E6 Interaction Chamber on either gas or solid targets. One 10 PW beam is the Pump-beam and the other is the Probe-beam. The focused Pump beam accelerates the electrons to relativistic energies. The accelerated electron bunches interact with the very high electro-magnetic field of the focused Probe beam. The layout of the experimental area E6 will be presented with several options for the experimental configurations.

    Nucleoporins are the constituents of nuclear pore complexes (NPCs) and are essential regulators of nucleocytoplasmic transport, gene expression and genome stability. The nucleoporin MEL-28/ELYS plays a critical role in post-mitotic NPC reassembly through recruitment of the NUP107-160 subcomplex, and is required for correct segregation of mitotic chromosomes. Here we present a systematic functional and structural analysis of MEL-28 in C. elegans early development and human ELYS in cultured cells. We have identified functional domains responsible for nuclear envelope and kinetochore localization, chromatin binding, mitotic spindle matrix association and chromosome segregation. Surprisingly, we found that perturbations to MEL-28's conserved AT-hook domain do not affect MEL-28 localization although they disrupt MEL-28 function and delay cell cycle progression in a DNA damage checkpoint-dependent manner. Our analyses also uncover a novel meiotic role of MEL-28. Together, these results show that MEL-28 has conserved structural domains that are essential for its fundamental roles in NPC assembly and chromosome segregation.

    The Gamma Beam System of ELI-Nuclear Physics is a high brilliance monochromatic gamma source based on the inverse Compton interaction between an intense high power laser and a bright electron beam with tunable energy. The source, currently being assembled in Magurele (Romania), is designed to provide a beam with tunable average energy ranging from 0.2 to 19.5 MeV, rms energy bandwidth down to 0.5% and flux of about 108 photons/s. The system includes a set of detectors for the diagnostic and complete characterization of the gamma beam. To evaluate the spatial distribution of the beam a gamma beam profile imager is required. For this purpose, a detector based on a scintillator target coupled to a CCD camera was designed and a prototype was tested at INFN-Ferrara laboratories. A set of analytical calculations and Monte Carlo simulations were carried out to optimize the imager design and evaluate the performance expected with ELI-NP gamma beam. In this work the design of the imager is described in detail, as well as the simulation tools used and the results obtained. The simulation parameters were tuned and cross-checked with the experimental measurements carried out on the assembled prototype using the beam from an x-ray tube.

    A large experiment like ATLAS at LHC (CERN), with over three thousand members and a shift crew of 15 people running the experiment 24/7, needs an easy and reliable tool to gather all the information concerning the experiment development, installation, deployment and exploitation over its lifetime. With the increasing number of users and the accumulation of stored information since the experiment start-up, the electronic logbook actually in use, ATLOG, started to show its limitations in terms of speed and usability. Its monolithic architecture makes the maintenance and implementation of new functionality a hard-to-almost-impossible process. A new tool ELisA has been developed to replace the existing ATLOG. It is based on modern web technologies: the Spring framework using a Model-View-Controller architecture was chosen, thus helping building flexible and easy to maintain applications. The new tool implements all features of the old electronic logbook with increased performance and better graphics: it uses the same database back-end for portability reasons. In addition, several new requirements have been accommodated which could not be implemented in ATLOG. This paper describes the architecture, implementation and performance of ELisA, with particular emphasis on the choices that allowed having a scalable and very fast system and on the aspects that could be re-used in different contexts to build a similar application.

    This work aim to prepare a program of studies on nuclear physics and astrophysics, which will be conducted at the new ELI-NP Laser facility, which actually is under construction in Bucharest, Romania. For the arguments treated, such activity has required also a multidisciplinary approach and knowledge in the fields of nuclear physics, astrophysics, laser and plasma physics join with also some competences on solid state physics related to the radiation detection. A part of this work has concerned to the experimental test, which have been performed in several laboratories and in order to study and increase the level of knowledge on the different parts of the project. In particular have been performed studies on the laser matter interaction at the ILIL laboratory of Pisa Italy and at the LENS laboratory in Catania, where (by using different experimental set-ups) has been investigated some key points concerning the production of the plasma stream. Test has been performed on several target configurations in terms of: composition, structure and size. All the work has been devoted to optimize the conditions of target in order to have the best performance on the production yields and on energies distribution of the inner plasma ions. A parallel activity has been performed in order to study the two main detectors, which will constitute the full detections system, which will be installed at the ELI-NP facility.

    At present, a fraction of all satellite observations are ultimately used for model assimilation. The satellite data assimilation process is computationally expensive and data are often reduced in resolution to allow timely incorporation into the forecast. This problem is only exacerbated by the recent launch of Geostationary Operational Environmental Satellite (GOES)-16 satellite and future satellites providing several order of magnitude increase in data volume. At the NOAA Earth System Research Laboratory (ESRL) we are researching the use of machine learning the improve the initial selection of satellite data to be used in the model assimilation process. In particular, we are investigating the use of deep learning. Deep learning is being applied to many image processing and computer vision problems with great success. Through our research, we are using convolutional neural network to find and mark regions of interest (ROI) to lead to intelligent extraction of observations from satellite observation systems. These targeted observations will be used to improve the quality of data selected for model assimilation and ultimately improve the impact of satellite data on weather forecasts. Our preliminary efforts to identify the ROI's are focused in two areas: applying and comparing state-of-art convolutional neural network models using the analysis data from the National Center for Environmental Prediction (NCEP) Global Forecast System (GFS) weather model, and using these results as a starting point to optimize convolution neural network model for pattern recognition on the higher resolution water vapor data from GOES-WEST and other satellite. This presentation will provide an introduction to our convolutional neural network model to identify and process these ROI's, along with the challenges of data preparation, training the model, and parameter optimization.

    Didactic and laboratory anatomical education have seen significant reductions in the medical school curriculum due, in part, to the current shift from basic science to more clinically based teaching in North American medical schools. In order to increase medical student exposure to anatomy, with clinical applicability, a student-run initiative called surgically oriented anatomy prosectors (SOAP) club was created within the extracurricular program at the Schulich School of Medicine and Dentistry, The University of Western Ontario, London, Canada. SOAP invites surgeons and residents from various surgical specialties to demonstrate, on a cadaver, a surgical procedure of their choosing. During the demonstration, the anatomy, as it relates to the surgical procedure, is discussed. The students then break into smaller groups to examine the relevant anatomy on the cadavers, during which time the discussion is broadened. The group continues the conversation in a social environment with refreshments. SOAP is one of the most popular extracurricular clubs with 65% of first and second year medical students registered as members. The high demand for SOAP, along with the positive participant feedback, may be due to its utilization of the principle of education through recreation, which seeks to provide opportunities for learning seamlessly throughout all facets of life. It also demonstrates the desire, amongst certain medical students, to learn applied anatomy, particularly within a surgical context. Copyright © 2012 American Association of Anatomists.

    A virtual-reality learning environment dedicated to prostate biopsies was designed to overcome the limitations of current classical teaching methods. The aim of this study was to validate reliability, face, content, and construct of the simulator. The simulator is composed of (a) a laptop computer, (b) a haptic device with a stylus that mimics the ultrasound probe, (c) a clinical case database including three-dimensional (3D) ultrasound volumes and patient data, and (d) a learning environment with a set of progressive exercises including a randomized 12-core biopsy procedure. Both visual (3D biopsy mapping) and numerical (score) feedback are given to the user. The simulator evaluation was conducted in an academic urology department on 7 experts and 14 novices who each performed a virtual biopsy procedure and completed a face and content validity questionnaire. The overall realism of the biopsy procedure was rated at a median of 9/10 by nonexperts (7.1-9.8). Experts rated the usefulness of the simulator for the initial training of urologists at 8.2/10 (7.9-8.3), but reported the range of motion and force feedback as significantly less realistic than novices (P=0.01 and 0.03, respectively). Pearson r correlation coefficient between correctly placed biopsies on the right and left side of the prostate for each user was 0.79 (Prealism and scoring system used.

    2014-08-01

    National plans are increasingly common but infrequently evaluated. The 2010 United States National Physical Activity Plan (NPAP) provided strategies to increase population levels of physical activity. This paper describes (i) the initial accomplishments of the NPAP sector teams, and (ii) results from a process evaluation to determine how the sectors operated, their cross-sector collaboration, challenges encountered, and positive experiences. During 2011, a quarterly reporting system was developed to capture sector-level activities. A year-end interview derived more detailed information. Interviews with 12 sector leads were recorded, transcribed verbatim, and analyzed for common themes. The 6 sectors worked on goals from the implementation plan that focused broadly on education, promotion, intervention, policy, collaboration, and evaluation. Through year-end interviews, themes were generated around operations, goal setting, and cross-sector collaboration. Challenges to the NPAP work included lack of funding and time, the need for marketing and promotion, and organizational support. Positive experiences included collaboration, efficiency of work, enhanced community dynamic, and accomplishments toward NPAP goals. These initial results on the NPAP sector teams can be used as a baseline assessment for future monitoring. The lessons learned may be useful to other practitioners developing evaluations around state- or national-level plans.

    This article presents a discussion of the key issues in influencing organisational change in NHS settings, in the development of workplace wellness interventions to improve employee health and wellbeing. To tackle poor public health and associated rising healthcare costs, there must be a focus on the root cause of many preventable diseases - unhealthy lifestyle choices. Workplace wellness initiatives are now an important prevention strategy adopted by socially responsible organisations to target the health and wellbeing of working age adults. Lessons learned from initiatives in secondary care suggest that effective implementation requires change in organisational 'health culture', through a combination of education, behaviour change intervention, needs-based facilities, and services and strategies for developing supportive and health-promoting work environments. Most of all, employers must demonstrate a commitment to health and wellness that is fully integrated with their mission, values and long-term vision, paving the way for sustainable lifestyle changes. Evaluation systems must be in place to measure the impact and outcomes of wellness schemes.

    A large body of evidence clearly shows that cancer patients experience significant health benefits with smoking cessation. Cancer Care Ontario, the provincial agency responsible for the quality of cancer services in Ontario, has undertaken a province-wide smoking cessation initiative. The strategies used, the results achieved, and the lessons learned are the subject of the present article. Evidence related to the health benefits of smoking cessation in cancer patients was reviewed. A steering committee developed a vision statement for the initiative, created a framework for implementation, and made recommendations for the key elements of the initiative and for smoking cessation best practices. New ambulatory cancer patients are being screened for their smoking status in each of Ontario's 14 regional cancer centres. Current or recent smokers are advised of the benefits of cessation and are directed to smoking cessation resources as appropriate. Performance metrics are captured and used to drive improvement through quarterly performance reviews and provincial rankings of the regional cancer centres. Regional smoking cessation champions, commitment from Cancer Care Ontario senior leadership, a provincial secretariat, and guidance from smoking cessation experts have been important enablers of early success. Data capture has been difficult because of the variety of information systems in use and non-standardized administrative and clinical processes. Numerous challenges remain, including increasing physician engagement; obtaining funding for key program elements, including in-house resources to support smoking cessation; and overcoming financial barriers to access nicotine replacement therapy. Future efforts will focus on standardizing processes to the extent possible, while tailoring the approaches to the populations served and the resources available within the individual regional cancer programs.

    Full Text Available Background: The design and initial experience with the e-learning course “Basis of Harvest and Preservation of Tissues” used as a support of an elective subject is presented. The aim of the e-learning course was to enable the students to learn the theoretical principles of the subject individually and to present the gained knowledge at the final seminar. Methods: All functions of the course were operated in Moodle, local application of the Charles University in Prague, Faculty of Medicine in Hradec Králové. The course was divided into 3 main topics corresponding with topics of lectures: 1. Principles of tissue and organ donation, 2. Low temperature preservation of cells, tissues and organs, 3. Quality and safety assurance in practice of tissue and procurement establishments. A test consisting of 5 questions selected randomly from the bank of questions followed each topic. If the student answers correctly at least 3 questions he is allowed to pass to the next topic. The fourth topic “Basic processes in the tissue establishment and principles of their validation” was added into the electronic version as a tool for repeating and improving of knowledge. The fifth topic was represented by a database for uploading theses presented by students at the final seminar. The final test consisted of 15 questions (5 ones from each basic topic. It was necessary to answer correctly at least 10 questions to receive a certificate of completing the course. Results: The course was put into operation during the summer term of the academic year 2012/2013. To the date 15 of September the total of 23 students enrolled (17, i.e. all students of the elective subject in the Czech version, 2 students of this subject in the English version, 2 postgraduate students and 2 medical doctors. All enrolled students used the course for on-line learning, downloading, or printing course study materials. All undergraduate students were obliged to use it for preparation

    1997-01-01

    This paper describes a project being undertaken to validate the performance of a Geographical Information System (GIS) being developed to predict, quantify and qualify the visual impact of proposed wind farm developments. In order to determine the optimal choice of terrain data model, elevation and topographic data sets, and visibility algorithms, a validation study for the Taff Ely Wind Farm has been commissioned. The issues involved in calculating and presenting visual impact are discussed, whilst a methodology for verifying the results is also described. Existing methods for presenting for visual impact of wind farms are limited and susceptible to error, whilst the interpretation of the results can often do more harm than good. The use of GIS to visualise the probable impacts is illustrated to add meaning to the results of a wind farm visibility study. (author)

    2017-08-01

    Full Text Available This article presents the strain-based experimental data for Ti–6Al–4V ELI under non-constant amplitude cyclic loading. Uniaxial strain-controlled fatigue experiments were conducted under three different loading conditions, including two-level block loading (i.e. high-low and low-high, periodic overload, and variable amplitude loading. Tests were performed under fully-reversed, and mean strain/stress conditions. For each test conducted, two sets of data were collected; the cyclic stress–strain response (i.e. hysteresis loops in log10 increments, and the peak and valley values of stress and strain for each cycle. Residual fatigue lives are reported for tests with two-level block loading, while for periodic overload and variable amplitude experiments, fatigue lives are reported in terms of number of blocks to failure.

    One of the experimental programs that will be carried out at the Extreme Light Infrastructure – Nuclear Physics (ELI-NP) facility is the production of exotic neutron-rich ion beams in an IGISOL facility via photofission in a stack of actinide targets placed at the center of a cell filled with He gas. Simulations with the Geant4 toolkit were done for the optimization of the target configuration that maximizes the rate of released photofission fragments. The cell geometry is established based on the stopping properties of these fragments. Studies, based on simulations with Geant4 and SIMION 8.1, of the space charge effect and its induced electric field in the gas cell are presented. Estimates of the extraction time and efficiency of the photofission fragments are derived.

    In this work, the response of HOS cells on Ti6Al4V ELI textured surfaces by a CO2 laser was evaluated. The test surfaces were; smooth Ti6Al4V, used as the control, and four textured surfaces with linear geometry. These four surfaces had different separation distances between textured lines, D1 (1000 microns), D2 (750 microns), D3 (500 microns) and D4 (250 microns). Toxicity of textured surfaces was assessed by MTT and the cellular adhesion test was performed using HOS ATCC CRL 1543 line cells. This test was done after 5 days of culture in a RPMI 1640 medium supplemented with 10% fetal bovine serum and 1% antibiotics. The results showed that the linear textures present 23% toxicity after 30 days of incubation, nevertheless, the adhesion tests results are inconclusive in such conditions and therefore the effect of the line separation on the cell adhesion cannot be determined.

    The ability to identify activated pathways that drive the growth and progression of cancer and to develop specific and potent inhibitors of key proteins in these pathways promises to dramatically change the treatment of cancer: A patient's cancer could be characterized at the molecular level and the information used to select the best treatment options. The development of successful therapies not only requires extensive target validation, but also new approaches to evaluating drug efficacy in animal models and in the clinic compared to the development of traditional cytotoxic agents. This article highlights Eli Lilly and Company's approach to developing targeted therapies, from target identification and validation through evaluation in the clinic. A selection of drugs in the Lilly Oncology pipeline is also discussed.

    To empower governments to formulate rational policies without pressure from any group, and to increase the use of evidence-based decision-making to adapt global recommendations on immunization to their local context, the WHO has recommended on multiple occasions that countries should establish National Immunization Technical Advisory Groups (NITAGs). The World Health Assembly (WHA) reinforced those recommendations in 2012 when Member States endorsed the Decade of Vaccines Global Vaccine Action Plan (GVAP). NITAGs are multidisciplinary groups of national experts responsible for providing independent, evidence-informed advice to health authorities on all policy-related issues for all vaccines across all populations. In 2012, according to the WHO-UNICEF Joint Reporting Form, among 57 countries eligible for immunization program financial support from the GAVI Alliance, only 9 reported having a functional NITAG. Since 2008, the Supporting Independent Immunization and Vaccine Advisory Committees (SIVAC) Initiative (at the Agence de Médecine Préventive or AMP) in close collaboration with the WHO and other partners has been working to accelerate and systematize the establishment of NITAGs in low- and middle-income countries. In addition to providing direct support to countries to establish advisory groups, the initiative also supports existing NITAGs to strengthen their capacity in the use of evidence-based processes for decision-making aligned with international standards. After 5 years of implementation and based on lessons learned, we recommend that future efforts should target both expanding new NITAGs and strengthening existing NITAGs in individual countries, along three strategic lines: (i) reinforce NITAG institutional integration to promote sustainability and credibility, (ii) build technical capacity within NITAG secretariats and evaluate NITAG performance, and (iii) increase networking and regional collaborations. These should be done through the development

    The ELI (Extreme Light Infrastructure) Beamlines facility in the Czech Republic, which is planned to complete the installation in 2015, is one of the four pillars of the ELI European project. Several laser beamlines with ultrahigh intensities and ultrashort pulses are foreseen, offering versatile radiation sources in an unprecedented energy range: laser-driven particle beams are expected to range between 1 and 50 GeV for electrons and from 100 MeV up to 3 GeV for protons. The number of particles delivered per laser shot is estimated to be 10{sup 9}–10{sup 10} for the electron beams and 10{sup 10}–10{sup 12} for the proton beams. The high energy and current values of the produced particles, together with the potentiality to operate at 10 Hz laser repetition rate, require an accurate study of the primary and secondary radiation fields to optimize appropriate shielding solutions: this is a key issue to minimize prompt and residual doses in order to protect the personnel, reduce the radiation damage of electronic devices and avoid strong limitations in the operational time. A general shielding study for the 10 PW (0.016 Hz) and 2 PW (10 Hz) laser beamlines is presented here. Starting from analytical calculations, as well as from dedicated simulations, the main electron and proton fields produced in the laser-matter interaction have been described and used to characterize the “source terms” in full simulations with the Monte Carlo code FLUKA. The secondary radiation fields have been then analyzed to assess a proper shielding. The results of this study and the proposed solutions for the beam dumps of the high energy beamlines, together with a cross-check analysis performed with the Monte Carlo code GEANT4, are presented.

    Matchmaking companies and theoretical perspectives on close relationships suggest that initial attraction is, to some extent, a product of two people's self-reported traits and preferences. We used machine learning to test how well such measures predict people's overall tendencies to romantically desire other people (actor variance) and to be desired by other people (partner variance), as well as people's desire for specific partners above and beyond actor and partner variance (relationship variance). In two speed-dating studies, romantically unattached individuals completed more than 100 self-report measures about traits and preferences that past researchers have identified as being relevant to mate selection. Each participant met each opposite-sex participant attending a speed-dating event for a 4-min speed date. Random forests models predicted 4% to 18% of actor variance and 7% to 27% of partner variance; crucially, however, they were unable to predict relationship variance using any combination of traits and preferences reported before the dates. These results suggest that compatibility elements of human mating are challenging to predict before two people meet.

    The Ocean Observatories Initiative (OOI) is a multi-decadal, NSF-funded program that will provide long-term, near real-time cabled and telemetered measurements of climate variability, ocean circulation, ecosystem dynamics, air-sea exchange, seafloor processes, and plate-scale geodynamics. The OOI platforms consist of seafloor sensors, fixed moorings, and mobile assets containing over 700 operational instruments in the Atlantic and Pacific oceans. Rutgers University operates the Cyberinfrastructure (CI) component of the OOI, which acquires, processes and distributes data to scientists, researchers, educators and the public. It will also provide observatory mission command and control, data assessment and distribution, and long-term data management. The Rutgers Data Management Team consists of a data manager and four data evaluators, who are tasked with ensuring data completeness and quality, as well as interaction with OOI users to facilitate data delivery and utility. Here we will discuss the procedures developed to guide the data team workflow, the automated QC algorithms and human-in-the-loop (HITL) annotations that are used to flag suspect data (whether due to instrument failures, biofouling, or unanticipated events), system alerts and alarms, long-term data storage and CF (Climate and Forecast) standard compliance, and the lessons learned during construction and the first several months of OOI operations.

    2007-01-01

    Profitable energy-efficiency potentials are often not exploited in industry since management tends not to focus on energy issues. Sharing experiences between companies reveals possibilities for reducing the transaction costs involved. For this purpose, regionally or locally-organised learning networks of companies have been established. Social mechanisms are used to motivate management to pay more attention to energy efficiency in Switzerland and Germany. The main elements of the activities include initial consultation for each company with an experienced engineer, agreement on a common target for energy-efficiency improvement, regular meetings with technical presentations and an exchange of experiences, yearly control of energy consumption and CO 2 emissions as well as scientific monitoring and evaluation of the process. The results of some evaluations show that substantial progress has been made in implementing organisational measures and investments in energy efficiency in the participating companies. The reasons for these achievements are discussed and conclusions drawn about the opportunities and limits of this instrument. Finally, a recommendation is made to implement this instrument on a broader level

    The Climate Data Initiative (CDI), launched by the Obama Administration in March of 2014, is an effort to leverage the extensive open Federal data to spur innovation and private-sector entrepreneurship in order to advance awareness of and preparedness for the impacts of climate change (see the White House fact sheet). The project includes an online catalog of climate-related datasets and data products in key areas of climate change risk and vulnerability from across the U.S. federal government through http://Climate.Data.gov. NASA was tasked with the implementation and management of the project and has been working closely with Subject Matter Experts (SMEs) and Data Curators (DCs) from across the Federal Government to identify and catalog federal datasets relevant for assessing climate risks and impacts. These datasets are organized around key themes and are framed by key climate questions. The current themes within CDI include: Arctic, Coastal Flooding, Ecosystem Vulnerability, Energy Infrastructure, Food Resilience, Human Health, Transportation, Tribal Nations and Water. This paper summarizes the main lessons learned from the last 2.5 years of CDI implementation.

    2016-01-01

    Introduction: The involvement of practitioners in the teaching and supervision of medical imaging technology students is central to students' learning. This article presents an overview of a learning partnership initiative, reinforced by an online platform to support students' learning and their medical imaging technologist supervisors' (MITs) teaching within a clinical learning environment in a New Zealand context. Methodology: Data were generated through a series of fourteen collaborative action research focus group meetings with MITs and student MITs. Results: The findings revealed that a robust relationship between a student and their MIT partner gave students an ‘anchor’ for learning and a sense of belonging. The online platform supported the relationship and provided an effective means for communication between students and their MIT partners. The relationship was not one-directional as it also supported the enhancement of MITs' practice. Conclusions: The recommendations from the study suggest learning partnerships between MITs and student MITs will be valuable in supporting teaching and learning respectively. MITs need to be better supported in their teaching role to enable them to make a greater investment in students' learning. A redistribution of funding for clinical education needs to be considered to support the MITs' central role in teaching medical imaging students. - Highlights: • Learning partnerships within a clinical setting support students' learning. • An online platform can provide online support when face-to-face support is not possible. • Learning partnerships can enhance MITs' practice.

    Objectives. Despite the importance of community health workers (CHWs) in strategies to reduce health disparities and the call to enhance their roles in research, little information exists on how to prepare CHWs involved in community–academic initiatives (CAIs). Therefore, the New York University Prevention Research Center piloted a CAI–CHW training program. Methods. We applied a core competency framework to an existing CHW curriculum and bolstered the curriculum to include research-specific sessions. We employed diverse training methods, guided by adult learning principles and popular education philosophy. Evaluation instruments assessed changes related to confidence, intention to use learned skills, usefulness of sessions, and satisfaction with the training. Results. Results demonstrated that a core competency–based training can successfully affect CHWs’ perceived confidence and intentions to apply learned content, and can provide a larger social justice context of their role and work. Conclusions. This program demonstrates that a core competency–based framework coupled with CAI-research–specific skill sessions (1) provides skills that CAI–CHWs intend to use, (2) builds confidence, and (3) provides participants with a more contextualized view of client needs and CHW roles.

    Learning Together is primarily an educational intervention, where paediatric registrars [SpRs] and General Practice (GP) registrars [GPSTs] see children together in a primary care setting. Over a six month period in 2013/2014, 44 learning pairs were set up mainly in North East and Central London. Proof of concept for the model at scale was achieved. Reported learning demonstrated: clinical learning themes of new knowledge, skill and communication skills; and collaborative themes of ongoing collaboration, satisfaction with team working and change in attitudes. These themes were identified in both sets of trainees. The self-reported learning is backed up by the results of a retrospective notes review of four common conditions based on NICE guidelines; constipation, asthma, feverish illness and eczema (CAFE). Guidance adherence improved from 57% before the intervention in solo GP training consultations to 72% during the joint clinic intervention (p Learning Together in its South London extension.

    This article explores facilitators and barriers to the impact and sustainability of a learning initiative to increase capacity of long-term care (LTC) homes to manage the mental health needs of older persons, through development of in-house Psychogeriatric Resource Persons (PRPs). Twenty interviews were conducted with LTC staff. Management support, particularly designation of time for PRP activities, development of PRP teams, and supportive learning strategies were significant factors affecting sustained knowledge transfer. Continuing education that is provided and evaluated on an ongoing basis, secures management commitment, is integrated within a broader system strategy, and provides on-the-job support has the greatest potential to affect care.

    Full Text Available In this paper, we describe an initial investigation that intended to qualify the elaboration and usability of didactic resources for Distance Learning (DL in the field of Languages/Portuguese Language and Reading. We present the planning of the resource, the selection of materials and the theoretical notions involved, and the initial design of the activity, which consisted in reading and evaluating the complexity of a set of short texts. The experience was successful only for a small controlled group of students and unsuccessful for the large uncontrolled group. In order to improve the devised resource and implement it didactically, there is the need to perform previous presential learning activities with the involved groups and proceed with the student’s evaluation of the results after the task is accomplished.

    Full Text Available Following the UN world summits on Climate Change (Paris 2015 and Habitat (Quito 2016, most European cities assume an active role to implement internationally agreed goals related to climate change, translated in the so-called New Urban Agenda. At the same time, the urban housing market is increasingly inaccessible for low- and middle-income households. To overcome problems such as failing housing supply and high energy-bills, groups of residents take initiatives to create and manage housing projects collectively; these initiatives are further indicated as ‘co-housing’.  The aim of this study is to create deeper understanding of the current rise of co-housing in Europe, and what it could mean in urban policies addressing energy transition and climate change. There are two domains where co-housing can become an important asset for urban development: design and maintenance of (semi-public space for climate change mitigation, and the transition to a circular metabolism in housing. Based on empirical data, this thesis concludes that co-housing projects present relevant models and approaches for reducing the energy consumption and for integrating renewable energies in the general housing stock. Engineers can learn from co-housing pioneers to advance the targets for energy-transition and further develop sustainable cities. The thesis contributes to the emerging body of knowledge with a new understanding of co-housing, analysing its ‘key-features’ with an interdisciplinary framework, in a European context. It adds a new perspective to existing co-housing research, which is dominated by social sciences, by drawing attention to the physical characteristics of co-housing, produced in architectural, planning and engineering processes (the technosphere. The choices made during design and building are not only shaped by the residents’ aims and perception of sustainability, but also influenced by technosphere-related institutions, such as the

    Informal workplace interprofessional learning occurs as health professionals interact with each other as part of everyday work practice. Participation in interprofessional team meetings is a practical way to foster learning. However, a gap exists in the availability of a reliable and valid instrument that adequately captures the nuances of informal workplace interprofessional learning in this setting. The purpose of this study was to develop a questionnaire to measure the different components of interprofessional learning that contribute to the quality of interprofessional learning within the interprofessional team meeting. Questionnaire items were developed from a review of the literature and interviews with health professionals. Exploratory factor analysis was used to determine the underlying factor structure. Two hundred and eighty-five health professionals completed a 98-item questionnaire. After elimination of unreliable items, the remaining items (n = 41) loaded onto four factors named personal and professional capacity; turning words into action-"walk the talk"; the rhetoric of interprofessional learning-"talk the talk"; and inclusiveness. Internal consistency was high for all sub-scales (Cronbach's alpha 0.91, 0.87, 0.83, and 0.83, respectively). Content, construct, and concurrent validity were assessed. The instrument developed in this study indicated consistency and robust psychometric properties. Future studies that further test the psychometric properties of the questionnaire will help to establish the usefulness of this measure in establishing evidence for the perceived effectiveness of interprofessional learning in a healthcare setting.

    Full Text Available Thermo hydrogen treatment (THT of titanium is a process in which hydrogen is used as a temporary alloying element in titanium alloys. It is an attractive approach for controlling the microstructure and thereby improving the final mechanical properties. In the present study, the microstructure of the original (non-hydrogenated sample has only α phase and the grains is coarse with an average size of ~ 650 μm. While the grain size of thermo hydrogen treated Ti-5Al-2.5Sn ELI alloy became finer and the mechanical properties were improved significantly. When the hydrogen content of the hydrogenated Ti-5Al-2.5Sn ELI alloy is 0.321wt.%, β phase and δ titanium hydride appear. Also the average grain size decreases to 450 μm. When the hydrogen content is 0.515wt.%, the grain size decreases to 220 μm. The mechanical properties were tested after dehydrogenation, and the mechanical properties improved significantly compared to the unhydrogenated specimens. The tensile strength of the Ti-5Al-2.5Sn ELI alloy improved by 17.7% when the hydrogen content increased to 0.920wt.%, at the same time the percentage reduction of area (Z increased by 33% and the impact toughness increased by 37%.

    Allen, Steven C.; Steckl, Andrew J.

    2007-06-01

    A phosphor-converted light-emitting diode (pcLED) luminaire featuring enhanced light extraction by internal reflection (ELiXIR) with efficacy of 60 lm/W producing 18 lumens of yellowish green light at 100 mA is presented. The luminaire consists of a commercial blue high power LED, a polymer hemispherical shell lens with interior phosphor coating, and planar aluminized reflector. High extraction efficiency of the phosphor-converted light is achieved by separating the phosphor from the LED and using internal reflection to steer the light away from lossy reflectors and the LED package and out of the device. At 10 and 500 mA, the luminaire produces 2.1 and 66 lumens with efficacies of 80 and 37 lm/W, respectively. Technological improvements over existing commercial LEDs, such as more efficient pcLED packages or, alternatively, higher efficiency green or yellow for color mixing, will be essential to achieving 150 200 lm/W solid-state lighting. Advances in both areas are demonstrated.

    Outlines the framework for promoting audit in general practice, created as one part of the health service reforms. Medical Audit Advisory Groups (MAAGs) were set up in each district with the aim of participation in audit of all general practitioners by April 1992. The activities undertaken have included those recommended by the Department of Health; the most significant of these being the appointment of lay facilitators who are able to assist general practitioners and primary care teams co-operate over efforts to improve the quality of care, and may offer one means of introducing some of the methods of total quality management into general practice. Discusses the problems which remain: audit is not yet sufficiently systematic, interface audit with secondary care is at a very early stage, the ways to involve managers and patients in audit remain to be clarified, and there is little evidence of the consequences of audit in terms of improved care. The Eli Lilly National Clinical Audit Centre has been set up within the Department of General Practice, University of Leicester, in order to address these issues.

    A large experiment like ATLAS at LHC (CERN), with over three thousand members and a shift crew of 15 people running the experiment 24/7, needs an easy and reliable tool to gather all the information concerning the experiment development, installation, deployment and exploitation over its lifetime. With the increasing number of users and the accumulation of stored information since the experiment start-up, the electronic logbook actually in use, ATLOG, started to show its limitations in terms of speed and usability. Its monolithic architecture makes the maintenance and implementation of new functionality a hard-to-almost-impossible process. A new tool ELisA has been developed to replace the existing ATLOG. It is based on modern web technologies: the Spring framework using a Model-View-Controller architecture was chosen, thus helping building flexible and easy to maintain applications. The new tool implements all features of the old electronic logbook with increased performance and better graphics: it uses the ...

    2016-11-01

    Full Text Available Direct metal laser sintering (DMLS is a relatively new technology that is developing rapidly. Since DMLS material is created by melting/solidifying tracks and layers from powder, even building geometry can influence the mechanical properties. To certify a material, the testing specimens must be designed and manufactured according to the appropriate standards. Miniaturised tensile DMLS samples could be a good alternative for express quality control, and could reduce the cost of DMLS-specific testing. In this study, as-built and stress-relieved miniaturised tensile DMLS Ti6Al4V (ELI specimens with different surface qualities were investigated. The fracture surfaces and mechanical properties of the mini-tensile specimens were analysed and compared with standard full-sized specimens also manufactured by DMLS. The obtained data showed the applicability of mini-tensile tests for the express analysis of DMLS objects if a correction factor is applied for the calculation of the load-bearing cross-section of the specimen.

    1998-01-01

    The Ely Creek watershed in Lee County, Virginia, contains an abundance of abandoned mined land (AML) seeps that contaminate the majority of the creek and its confluence into Big Stone Creek. Contaminated sediments had high concentrations of iron (∼10,000 mg/kg), aluminum (∼1,500 mg/kg), magnesium (∼400 mg/kg) and manganese (∼150 mg/kg). Copper and zinc generally ranged from 3 to 20 mg/kg. Benthic macroinvertebrates surveys at six of 20 sites sampled in the watershed yielded no macroinvertebrates, while eight others had total abundances of 1 to 9 organisms. Four reference sites contained ≥100 organisms and at least 14 different taxa. Laboratory, 10-day survival/impairment sediments tests with Daphnia magna did not support the field data. Mortality of 92 to 100% for D. magna occurred in samples collected from six cities. Daphnid reproduction was more sensitive than laboratory test organism survivorship; however, neither daphnid survivorship nor reproduction were good predictors of taxa richness. Laboratory test concerns included the use of a reference diluent water rather than site specific diluent water

    2010-01-01

    In response to the White House Educate to Innovate campaign, NASA developed a new science, technology, engineering, and mathematics (STEM) education program for non-traditional audiences that also focused on public-private partnerships and nationwide participation. NASA recognized that summer break is an often overlooked but opportune time to engage youth in STEM experiences, and elevated its ongoing commitment to the cultivation of diversity. The Summer of Innovation (SoI) is the resulting initiative that uses NASA's unique missions and resources to boost summer learning, particularly for students who are underrepresented, underserved and underperforming in STEM. The SoI pilot, launched in June 2010, is a multi-faceted effort designed to improve STEM teaching and learning through partnership, multi-week summer learning programs, special events, a national concluding event, and teacher development. The SoI pilot features strategic infusion of NASA content and educational resource materials, sustainability through STEM Learning Communities, and assessments of effectiveness of SoI interventions with other pilot efforts. This paper examines the inception and development of the Summer of Innovation pilot project, including achievements and effectiveness, as well as lessons learned for future efforts.

    2014-01-01

    We hypothesize that the initiative of a robot during a collaborative task with a human can influence the pace of interaction, the human response to attention cues, and the perceived engagement. We propose an object learning experiment where the human interacts in a natural way with the humanoid iCub. Through a two-phases scenario, the human teaches the robot about the properties of some objects. We compare the effect of the initiator of the task in the teaching phase (human or robot) on the rhythm of the interaction in the verification phase. We measure the reaction time of the human gaze when responding to attention utterances of the robot. Our experiments show that when the robot is the initiator of the learning task, the pace of interaction is higher and the reaction to attention cues faster. Subjective evaluations suggest that the initiating role of the robot, however, does not affect the perceived engagement. Moreover, subjective and third-person evaluations of the interaction task suggest that the attentive mechanism we implemented in the humanoid robot iCub is able to arouse engagement and make the robot's behavior readable.

    With the advent of new imaging modalities, radiologists are faced with handling increasing volumes of data for diagnosis and treatment planning. The use of automated and intelligent systems is becoming essential in such a scenario. Machine learning, a branch of artificial intelligence, is increasingly being used in medical image analysis applications such as image segmentation, registration and computer-aided diagnosis and detection. Histopathological analysis is currently the gold standard for classification of brain tumors. The use of machine learning algorithms along with extraction of relevant features from magnetic resonance imaging (MRI) holds promise of replacing conventional invasive methods of tumor classification. The aim of the study is to classify gliomas into benign and malignant types using MRI data. Retrospective data from 28 patients who were diagnosed with glioma were used for the analysis. WHO Grade II (low-grade astrocytoma) was classified as benign while Grade III (anaplastic astrocytoma) and Grade IV (glioblastoma multiforme) were classified as malignant. Features were extracted from MR spectroscopy. The classification was done using four machine learning algorithms: multilayer perceptrons, support vector machine, random forest and locally weighted learning. Three of the four machine learning algorithms gave an area under ROC curve in excess of 0.80. Random forest gave the best performance in terms of AUC (0.911) while sensitivity was best for locally weighted learning (86.1%). The performance of different machine learning algorithms in the classification of gliomas is promising. An even better performance may be expected by integrating features extracted from other MR sequences. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

The GPEI built on many lessons learned from smallpox eradication, including the large-scale deployment of technical assistance, implementing agendas of innovation and research and the use of professionally planned and guided advocacy. By the year 2000, the incidence of polio globally had decreased by 99% compared with the estimated >350,000 cases reported from 125 endemic countries in 1988. By 2002, three WHO Regions (the Americas, Western Pacific and European Regions) had been certified polio-free. By 2005, transmission of indigenous wild poliovirus (WPV) had been interrupted in all but 4 'endemic' countries: India, Nigeria, Pakistan and Afghanistan, where eradication efforts effectively stalled. WPV exported from northern Nigeria and northern India subsequently caused >50 outbreaks and paralysed >1500 children in previously polio-free countries across Asia and Africa. In each of the four remaining polio-endemic countries different challenges, or a combination of factors, prevented to build up sufficient levels of population immunity to stop transmission. Consequently, specific strategies were increasingly tailored to each setting. A new 2010-2012 GPEI Strategic Plan was developed which brought together several approaches to overcome the remaining hurdles to eradication, including the large-scale use of bivalent oral poliovaccine (bOPV) in supplementary immunization activities (SIAs). By the end of 2010, the impact of the new GPEI Strategic Plan 2010-2012 was apparent. Compared to 2009, the number of new polio cases in 2010 fell by 95% in both northern Nigeria and northern India, the world's largest remaining reservoirs of indigenous WPVs. By mid-2011, India had not reported a polio case for more than 5 months, and in

    Assessment of interprofessional education (IPE) frequently focuses on students' learning outcomes including changes in knowledge, skills, and/or attitudes. While a foundational education in the values and information of their chosen profession is critical, interprofessional learning follows a continuum from formal education to practice. The continuum increases in significance and complexity as learning becomes more relationship based and dependent upon the ability to navigate complex interactions with patients, families, communities, co-workers, and others. Integrating IPE into collaborative practice is critical to enhancing students' experiential learning, developing teamwork competencies, and understanding the complexity of teams. This article describes a project that linked students with a hospital-based quality-improvement effort to focus on the acquisition and practice of teamwork skills and to determine the impact of teamwork on patient and quality outcome measures. A hospital unit was identified with an opportunity for improvement related to quality care, patient satisfaction, employee engagement, and team behaviours. One hundred and thirty-seven students from six health profession colleges at the Medical University of South Carolina underwent TeamSTEPPS® training and demonstrated proficiency of their teamwork-rating skills with the TeamSTEPPS® Team Performance Observation Tool (T-TPO). Students observed real-time team behaviours of unit staff before and after staff attended formal TeamSTEPPS® training. The students collected a total of 778 observations using the T-TPO. Teamwork performance on the unit improved significantly across all T-TPO domains (team structure, communication, leadership, situation monitoring, and mutual support). Significant improvement in each domain continued post-intervention and at 15-month follow-up, improvement remained significant compared to baseline. Student engagement in TeamSTEPPS® training and demonstration of their

    Organizational effects on job satisfaction, burnout, work-life balance, and perceived support have not been studied in the context of the clinical learning environment. We evaluated the relationship between academic resources and resident well-being, the clinical learning environment, and in-service examination performance of surgical residents. Residents of general surgery and surgical specialty programs were recruited from March 2016 through June 2016 across the Southeast, Mid-Atlantic, and Northeast regions. Program directors were asked to allow distribution of a paper survey or to forward an electronic survey link onto residents. Five dichotomous questions were asked regarding access to academic resources. Validated measures were obtained assessing resident well-being and perceived clinical learning environment. Data were analyzed through t-tests and chi-squared test of independence. We received 276 respondents across 50 programs. Residents perceiving adequate support to succeed had less burnout (P = 0.008), better resilience (P = 0.009), better job satisfaction (P workplace climate (P < 0.001), better organizational support (P < 0.001), and were more likely to have high performance on the in-service examination (P = 0.001). Specific resources including educational stipends, review questions, in-service board prep, and support for poor performers correlated with improved well-being and perceived clinical learning environment. Provision of academic resources has implications beyond in-service examination performance, correlating with improved resident well-being and perceptions of the clinical learning environment.

    Full Text Available The proliferation of increasingly interactive e-reader devices such as the Amazon Kindle represents an opportunity to explore their evolving pedagogical value. This study aims to investigate how use of the Kindle can enhance individuals’ English language learning—more specifically their attitudes, reading comprehension, vocabulary development and pronunciation performance—in the context of informal and lifelong learning in Palestine, and to explore the further potential of scaling up the use of e-readers at a national level. At the piloting stage of this initiative, the study operated at two levels (micro and meso of the M3 evaluation framework. Mixed methods were used: qualitative data were obtained through a case study of the practices and perceptions of two teachers in two classrooms in the Qalqilia center and quantitative data were collected through a survey of 114 learners. The study shows that the Kindle’s technological affordances are effective in creating a flexible, authentic and interactive environment for English language learning, provided that teachers change their teaching methods to take full advantage of the features of mobile technologies to create innovative learning approaches aligned with the needs of the e-generation. It was also found that despite some concerns with the usability issue, attitudes towards learning English changed positively and learners’ vocabulary and pronunciation improved.

    Computed Tomography (CT) is one of the most important medical imaging modality. CT images can be used to assist in the detection and diagnosis of lesions and to facilitate follow-up treatment. However, CT images are vulnerable to noise. Actually, there are two major source intrinsically causing the CT data noise, i.e., the X-ray photo statistics and the electronic noise background. Therefore, it is necessary to doing image quality assessment (IQA) in CT imaging before diagnosis and treatment. Most of existing CT images IQA methods are based on human observer study. However, these methods are impractical in clinical for their complex and time-consuming. In this paper, we presented a blind CT image quality assessment via deep learning strategy. A database of 1500 CT images is constructed, containing 300 high-quality images and 1200 corresponding noisy images. Specifically, the high-quality images were used to simulate the corresponding noisy images at four different doses. Then, the images are scored by the experienced radiologists by the following attributes: image noise, artifacts, edge and structure, overall image quality, and tumor size and boundary estimation with five-point scale. We trained a network for learning the non-liner map from CT images to subjective evaluation scores. Then, we load the pre-trained model to yield predicted score from the test image. To demonstrate the performance of the deep learning network in IQA, correlation coefficients: Pearson Linear Correlation Coefficient (PLCC) and Spearman Rank Order Correlation Coefficient (SROCC) are utilized. And the experimental result demonstrate that the presented deep learning based IQA strategy can be used in the CT image quality assessment.

    Ti 6Al-4V ELI (Extra Low Interstitial)alloy containing 6wt% of aluminum, 4wt% of vanadium with controlled level of iron and oxygen is one of most popular alloy employed in biomedical applications as implant material. Heat treatment process for titanium alloys becomes important and could be performed by some of different ways in order to develop microstructure as well as its properties. The objective of this paper is to study the effects of solution treatment temperature on microstructure and mechanical properties of as-cast Ti-6Al-4V ELI especially microhardness value. The alloy was melted by single arc melting furnace with a water-cooled copper crucible hearth under argon atmosphere and then casted. It was heat treated through solution treatment at 3 (three) different temperaturesi.e. 850°C, 950°C and 1050°C in an argon gas atmosphere for around 30 minutes. After solution treatment, samples were water quenched and then aged at temperature of 500°C for 4 hours. To investigate its microstructure, the alloy was investigated under optical microscope and scanning electron microscope (SEM). It was observed Widmanstätten microstructure consisting of mixture α and β phase with basket-weave pattern. The Vickers microhardness test was performed and the results exhibited the optimum value was obtained at temperature of 950°C of solution treatment. From the observation, it revealed that the heat treatment has substantial effect on microstructural properties where microhardness increased due to formation of α' martensite structure. It was showed also that solution treatment followed by aging could improve mechanical properties especially microhardness value of Ti-6Al-4V ELI alloy. These results were suggesting the optimized conditions of heat treatment to obtain the best microstructure properties and microhardness value.

    Networks of interconnected neocortical representations of prior knowledge, "schemas," facilitate memory for congruent information. This facilitation is thought to be mediated by augmented encoding and accelerated consolidation. However, it is less clear how schema affects retrieval. Rodent and human studies to date suggest that schema-related memories are differently retrieved. However, these studies differ substantially as most human studies implement pre-experimental world-knowledge as schemas and tested item or nonspatial associative memory, whereas animal studies have used intraexperimental schemas based on item-location associations within a complex spatial layout that, in humans, could engage more strategic retrieval processes. Here, we developed a paradigm conceptually linked to rodent studies to examine the effects of an experimentally learned spatial associative schema on learning and retrieval of new object-location associations and to investigate the neural mechanisms underlying schema-related retrieval. Extending previous findings, we show that retrieval of schema-defining associations is related to activity along anterior and posterior midline structures and angular gyrus. The existence of such spatial associative schema resulted in more accurate learning and retrieval of new, related associations, and increased time allocated to retrieve these associations. This retrieval was associated with right dorsolateral prefrontal and lateral parietal activity, as well as interactions between the right dorsolateral prefrontal cortex and medial and lateral parietal regions, and between the medial prefrontal cortex and posterior midline regions, supporting the hypothesis that retrieval of new, schema-related object-location associations in humans also involves augmented monitoring and systematic search processes.

    Shuichiro Kobayashi

    Full Text Available ABSTRACT Purpose: To determine the predictive factors for postoperative urinary incontinence (UI following holmium laser enucleation of the prostate (HoLEP during the initial learning period. Patients and Methods: We evaluated 127 patients with benign prostatic hyperplasia who underwent HoLEP between January 2011 and December 2013. We recorded clinical variables, including blood loss, serum prostate-specific antigen levels, and the presence or absence of UI. Blood loss was estimated as a decline in postoperative hemoglobin levels. The predictive factors for postoperative UI were determined using a multivariable logistic regression analysis. Results: Postoperative UI occurred in 31 patients (24.4%, but it cured in 29 patients (93.5% after a mean duration of 12 weeks. Enucleation time >100 min (p=0.043 and blood loss >2.5g/dL (p=0.032 were identified as significant and independent risk factors for postoperative UI. Conclusions: Longer enucleation time and increased blood loss were independent predictors of postoperative UI in patients who underwent HoLEP during the initial learning period. Surgeons in training should take care to perform speedy enucleation maneuver with hemostasis.

    Automated high throughput scanning microscopy is a fast developing screening technology used in cytogenetic laboratories for the diagnosis of leukemia or other genetic diseases. However, one of the major challenges of using this new technology is how to efficiently detect the analyzable metaphase chromosomes during the scanning process. The purpose of this investigation is to develop a computer aided detection (CAD) scheme based on deep learning technology, which can identify the metaphase chromosomes with high accuracy. The CAD scheme includes an eight layer neural network. The first six layers compose of an automatic feature extraction module, which has an architecture of three convolution-max-pooling layer pairs. The 1st, 2nd and 3rd pair contains 30, 20, 20 feature maps, respectively. The seventh and eighth layers compose of a multiple layer perception (MLP) based classifier, which is used to identify the analyzable metaphase chromosomes. The performance of new CAD scheme was assessed by receiver operation characteristic (ROC) method. A number of 150 regions of interest (ROIs) were selected to test the performance of our new CAD scheme. Each ROI contains either interphase cell or metaphase chromosomes. The results indicate that new scheme is able to achieve an area under the ROC curve (AUC) of 0.886+/-0.043. This investigation demonstrates that applying a deep learning technique may enable to significantly improve the accuracy of the metaphase chromosome detection using a scanning microscopic imaging technology in the future.

    Full Text Available Background: The endoscopic vein harvesting (EVH method has been used in coronary artery bypass surgery in many countries. We started using the EVH method recently, and investigated the results during the early learning period. Methods: Between March 2012 and June 2014, 75 patients (31 patients in the EVH method group, and 44 patients in the open method group who underwent isolated first-time coronary artery bypass grafting using vein grafts were retrospectively analyzed with respect to the early outcomes including graft patency and risk factors for leg wound complications. For assessing the patency of vein graft, we performed coronary computed tomography angiography during the immediate postoperative period and 6 months later. Results: Mean harvesting time of endoscopic method was about 15 minutes. Patency rate during the immediate operative period and the 6-month patency rate were similar between the two groups (postoperative period: EVH 100% vs. open method 94.4%, p=0.493; at 6 months: EVH 93.3% vs. open method 90.9%, p=0.791. Leg wound complications occurred more frequently in the open method group (EVH 3.2% vs. open method 13.6%, p=0.127. According to the analysis, age was an independent risk factor for leg wound complications. Conclusion: EVH is a feasible method even for beginners and can be performed satisfactorily during their learning period.

    A comprehensive characterization of neuronal cell types, their distributions, and patterns of connectivity is critical for understanding the properties of neural circuits and how they generate behaviors. Here we review the experiences of the BRAIN Initiative Cell Census Consortium, ten pilot projects funded by the U.S. BRAIN Initiative, in developing, validating, and scaling up emerging genomic and anatomical mapping technologies for creating a complete inventory of neuronal cell types and their connections in multiple species and during development. These projects lay the foundation for a larger and longer-term effort to generate whole-brain cell atlases in species including mice and humans. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available The necessity of eLearning support of the university studies is setting up (or was setting up at the universities all over the world. This paper compares the eLearning technologies available at Mendel University in Brno (MUAF, Czech Republic, and Polytechnic University in Madrid (UPM, Spain, in the context of different conditions at both universities. The level of using of these technologies and practical experiences with them are evaluated too. In concrete this paper deals with the systems GATE (GAbinete de TeleEducación and AulaWeb, used at the UPM and system ELIS, used at MUAF. The fifteen-year experiences with development of eLearning at UPM are very valuable study material for the developers of the ELIS system. Some, especially conception properties of the ELIS system, can be, on the other hand, useful for inspiration vice versa.

    Full Text Available The Listen, Live and Learn (LLL initiative at Stellenbosch University (SU is a senior student housing model with the aim of providing an experiential opportunity for students to make contact with ‘the other’. It is posited on the social contact theory assumption that if people of different genders, races, ethnicities, and/or religion make contact and interact with one another on an equal level, then less stereotyping by them will occur.The initiative therefore aims to enhance interaction between diverse students and to enable social integration. However, as diversity is a core element of LLL, an application and selection process had to be developed in order to provide a holistic, transparent, unbiased and scaleable tool. The present results suggest that the application and selection process, specifically developed for the enhancement of diversity within the LLL initiative, maintained the distribution of race and gender, as constructs of diversity throughout the process. The conclusion can be drawn that the process is holistic, transparent, unbiased and scaleable while providing a practical example of a standardised alternative selection process for programmes seeking to increase diversity.

    This cross-sectional study aimed to determine the prevalence and the factors associated with sexual initiation among the late adolescents in 6 institutions of higher learning in Malaysia. A total of 1572 students completed self-administered questionnaires between April and September 2013. Hierarchical multivariate logistic regression analyses stratified by gender were employed to identify the correlates of sexual initiation. The analyses were further adjusted by sampling weights. The overall prevalence of sexual initiation was 9.8% (95% confidence interval [CI] = 8.3-11.6), 18.1% (95% CI = 15.1-21.5) among males, and 4.1% (95% CI = 2.9-5.9) among females. The risk factors identified in this study supported the influence of the individual, family, and peer factors in the social-ecological model on adolescents' behaviors. The findings suggest the need for risk-reduction strategies aimed at the individual, family, and peer levels as well as the importance of gender-specific focus in assuring better outcomes. © 2016 APJPH.

    The author spent the period from March 22 to July 10, 1987, at the GAMMA 10 tandem-mirror experiment at the University of Tsukuba in Tsukuba, Japan. The purpose of this extended trip was to install on GAMMA 10 one of the end-loss-ion spectrometers (ELIS) used on TMX-U (Tandem Mirror Experiment-Upgrade) at LLNL and to make plasma measurements there with this diagnostic instrument. This report discusses the considerable planning and preparations that preceded the trip, the actual experience with the ELIS equipment at GAMMA 10, data and results obtained while the author was there, GAMMA 10 experimental procedures, the scientific and technical support during the stay, and some final comments and suggestions concerning an international exchange such as this one. The data acquired on GAMMA 10 while there, along with earlier data, present an encouraging picture of a plasma in a thermal-barrier mode in a tandem-mirror, magnetic-fusion machine. 6 refs

    Full Text Available The astrophysical p-process is an important way of nucleosynthesis to produce the stable and proton-rich nuclei beyond Fe which can not be reached by the s- and r-processes. In the present study, the impact of nuclear ingredients, especially the nuclear potential, level density and strength function, to the astrophysical re-action rates of (p,γ, (α,γ, (γ,p, and (γ,α reactions are systematically studied. The calculations are performed basad on the modern reaction code TALYS for about 3000 stable and proton-rich nuclei with 12≤Z≤110. In particular, both of the Wood-Saxon potential and the microscopic folding potential are taken into account. It is found that both the capture and photonuclear reaction rates are very sensitive to the nuclear potential, thus the better determination of nuclear potential would be important to reduce the uncertainties of reaction rates. Meanwhile, the Extreme Light Infrastructure-Nuclear Physics (ELI-NP facility is being developed, which will provide the great opportunity to experimentally study the photonuclear reactions in p-process. Simulations of the experimental setup for the measurements of the photonuclear reactions 96Ru(γ,p and 96Ru(γ,α are performed. It is shown that the experiments of photonuclear reactions in p-process based on ELI-NP are quite promising.

    Laser accelerated proton beams represent nowadays an attractive alternative to the conventional ones and they have been proposed in different research fields. In particular, the interest has been focused in the possibility of replacing conventional accelerating machines with laser-based accelerators in order to develop a new concept of hadrontherapy facilities, which could result more compact and less expensive. With this background the ELIMED (ELIMED: ELI-Beamlines MEDical applications) research project has been launched by LNS-INFN researchers (Laboratori Nazionali del Sud-Istituto Nazionale di Fisica Nucleare, Catania, IT) and ASCR-FZU researchers (Academy of Sciences of the Czech Republic-Fyzikální ústar, Prague, Cz), within the pan-European ELI-Beamlines facility framework. Its main purposes are the demonstration of future applications in hadrontherapy of optically accelerated protons and the realization of a laser-accelerated ion transport beamline for multidisciplinary applications. Several challenges, starting from laser-target interaction and beam transport development, up to dosimetric and radiobiological issues, need to be overcome in order to reach the final goals. The design and the realization of a preliminary beam handling and dosimetric system and of an advanced spectrometer for high energy (multi-MeV) laser-accelerated ion beams will be shortly presented in this work.

  7. Delimiting the Prospect of Openness: An Examination of Initial Student Approaches to E-Learning

    Directory of Open Access Journals (Sweden)

    2011-02-01

    Full Text Available When converting from a paper-based distance mode to an online mode of teaching, certain expectations arise that students may engage not only in the development of extended research activity but that the quality of discussion and thinking will change. With access to open-ended discussion within the online forum the opportunity is afforded to students to share ideas and in turn develop their shared knowledge, a facility denied to them when in the paper distance mode. However, in a recent study conducted in New Zealand, it was shown that despite having access to online forums students moving to an online platform refrained from participation in this social exchange. A possible explanation for this indifference was thought to be the students realising that the online exchange made no impact on their assessment. Hence, the collaborative rhetoric of Web 2.0 made little impact when the summative evaluation remained unchanged from previous paper-based assessment. This paper reports on the introduction of online learning at a private tertiary college in New Zealand and describes the response of students who found difficulty in reconciling a community of learners and openness within what was perceived as an evaluation that remained individualistic and competitive in nature.

    Full Text Available The present study assesses the efficacy of a semester-long undergraduate sustainability curriculum designed from a systems approach. The three-course curriculum, which incorporated environmental science and ethics courses along with an integrative course using a community-based learning pedagogy, was intended to provide students with experience using knowledge and skills from distinct disciplines in a holistic way in order to address the complex problems of the human acceptance of and response to anthropogenic climate change. In the fall of 2013, 23 of the 24 sophomore general education students enrolled in the three courses were surveyed at the beginning and end of the semester; 17 of those same students completed the survey again in the spring of 2016, their senior year. Results, which focus on the 17 students who continued to participate through their senior year, were analyzed with quantitative and qualitative methodologies. The pre/post data from the surveys demonstrated significant improvement in climate literacy, certainty, concern and urgency over the course of the semester; the senior data indicated that those improvements were largely retained. The study also suggests that the nine-credit curriculum improved transferable skills such as interdisciplinary thinking, self-confidence and public speaking. A qualitative analysis of three student cases, informed by a focus group (n = 7 of seniors along with other sources of information, suggested retention of such transferable skills, and, in some cases, deeper involvement in climate and sustainability action.

    In 2015, the International Confederation of Midwives (ICM) launched the Midwifery Services Framework (MSF): an evidence-based tool to guide countries through the process of improving their sexual, reproductive, maternal and newborn health services through strengthening and developing the midwifery workforce. The MSF is aligned with key global architecture for sexual, reproductive, maternal and newborn health and human resources for health. This third in a series of three papers describes the experience of starting to implement the MSF in the first six countries that requested ICM support to adopt the tool, and the lessons learned during these early stages of implementation. The early adopting countries selected a variety of priority work areas, but nearly all highlighted the importance of improving the attractiveness of midwifery as a career so as to improve attraction and retention, and several saw the need for improvements to midwifery regulation, pre-service education, availability and/or accessibility of midwives. Key lessons from the early stages of implementation include the need to ensure a broad range of stakeholder involvement from the outset and the need for an in-country lead organisation to maintain the momentum of implementation even when there are changes in political leadership, security concerns or other barriers to progress.

    As an emerging sub-field of music information retrieval (MIR), music imagery information retrieval (MIIR) aims to retrieve information from brain activity recorded during music cognition-such as listening to or imagining music pieces. This is a highly inter-disciplinary endeavor that requires expertise in MIR as well as cognitive neuroscience and psychology. The OpenMIIR initiative strives to foster collaborations between these fields to advance the state of the art in MIIR. As a first step, electroencephalography (EEG) recordings of music perception and imagination have been made publicly available, enabling MIR researchers to easily test and adapt their existing approaches for music analysis like fingerprinting, beat tracking or tempo estimation on this new kind of data. This paper reports on first results of MIIR experiments using these OpenMIIR datasets and points out how these findings could drive new research in cognitive neuroscience.

    In light of the recent Ebola outbreak, there is a critical need for effective disaster management systems in Liberia and other West African nations. To this end, the West Africa Disaster Preparedness Initiative held a disaster management exercise in conjunction with the Liberian national government on November 24-25, 2015. During this tabletop exercise (TTX), interactions within and between the 15 counties and the Liberian national government were conducted and observed to refine and validate the county and national standard operating procedures (SOPs). The exercise took place in three regional locations throughout Liberia: Monrovia, Buchanan, and Bong. The TTX format allowed counties to collaborate utilizing open-source software platforms including Ushahidi, Sahana, QGIS, and KoBoCollect. Four hundred sixty-seven individuals (representing all 15 counties of Liberia) identified as key actors involved with emergency operations and disaster preparedness participated in the exercise. A qualitative survey with open-ended questions was administered to exercise participants to determine needed improvements in the disaster management system in Liberia. Key findings from the exercise and survey include the need for emergency management infrastructure to extend to the community level, establishment of a national disaster management agency and emergency operations center, customized local SOPs, ongoing surveillance, a disaster exercise program, and the need for effective data sharing and hazard maps. These regional exercises initiated the process of validating and refining Liberia's national and county-level SOPs. Liberia's participation in this exercise has provided a foundation for advancing its preparedness, response, and recovery capacities and could provide a template for other countries to use.

    2016-01-01

    To inspire young students (grades 6-12) to become medical practitioners and biomedical engineers, it is necessary to expose them to key concepts of the field in a way that is both exciting and informative. Recent advances in medical image acquisition, manipulation, processing, visualization, and display have revolutionized the approach in which the human body and internal anatomy can be seen and studied. It is now possible to collect 3D, 4D, and 5D medical images of patient specific data, and display that data to the end user using consumer level 3D stereoscopic display technology. Despite such advancements, traditional 2D modes of content presentation such as textbooks and slides are still the standard didactic equipment used to teach young students anatomy. More sophisticated methods of display can help to elucidate the complex 3D relationships between structures that are so often missed when viewing only 2D media, and can instill in students an appreciation for the interconnection between medicine and technology. Here we describe the design, implementation, and preliminary evaluation of a 3D virtual anatomy puzzle dedicated to helping users learn the anatomy of various organs and systems by manipulating 3D virtual data. The puzzle currently comprises several components of the human anatomy and can be easily extended to include additional organs and systems. The 3D virtual anatomy puzzle game was implemented and piloted using three display paradigms - a traditional 2D monitor, a 3D TV with active shutter glass, and the DK2 version Oculus Rift, as well as two different user interaction devices - a space mouse and traditional keyboard controls.

    Full Text Available This paper is a continuance of an empirical work on hotels in a developing country and its acceptance on environmental impact. The study measured the responsiveness of small and medium accommodations (SMAs in Kuala Lumpur, Malaysia towards environmental management, by means of their awareness, attitudes and opinion on the meaning, marketability and practicality of environmental management in an accommodation property. A combination of quantitative and qualitative approach was used for the study. The study found those respondents’ perceptions on the meaning, marketability and practicality of environmental management that SMAs are generally positive about the relevance of environmental issues in their operations and their role in it. However, the SMAs do not go beyond the basic common sense of cutting their water and energy costs. The chief reason for the lack of motivation to do more is lack of awareness on how to adopt environmental management in their operations. The study also found path towards a wider adoption of environmental management among SMAs is still rough because there is very little pressure from the authorities and relevant stakeholders for them to change. Without external drivers, it is difficult to expect SMAs to go beyond their normal business activity as internal constraints and lack of guidance on how to play a more significant role in sustainable development are hampering such move. To overcome the lack of drivers, this paper is proposing e-learning as a way to promote wider understanding and acceptance on environmental management for SMAs. Thus, the paper discusses the situation by addressing key issues such as students, teachers and organizational issues, information technology delivery design and top level support, outcome assessment, flexibility as well as supplement versus substitute issues.

    Since 1998, the Veterans Health Administration (VHA) Quality Enhancement Research Initiative (QUERI) has supported more rapid implementation of research into clinical practice. With the passage of the Veterans Access, Choice and Accountability Act of 2014 (Choice Act), QUERI further evolved to support VHA's transformation into a Learning Health Care System by aligning science with clinical priority goals based on a strategic planning process and alignment of funding priorities with updated VHA priority goals in response to the Choice Act. QUERI updated its strategic goals in response to independent assessments mandated by the Choice Act that recommended VHA reduce variation in care by providing a clear path to implement best practices. Specifically, QUERI updated its application process to ensure its centers (Programs) focus on cross-cutting VHA priorities and specify roadmaps for implementation of research-informed practices across different settings. QUERI also increased funding for scientific evaluations of the Choice Act and other policies in response to Commission on Care recommendations. QUERI's national network of Programs deploys effective practices using implementation strategies across different settings. QUERI Choice Act evaluations informed the law's further implementation, setting the stage for additional rigorous national evaluations of other VHA programs and policies including community provider networks. Grounded in implementation science and evidence-based policy, QUERI serves as an example of how to operationalize core components of a Learning Health Care System, notably through rigorous evaluation and scientific testing of implementation strategies to ultimately reduce variation in quality and improve overall population health.

    Zhao, Zhuang; Chen, Jing; Tan, Hua; Lin, Xin; Huang, Weidong

    2017-07-01

    In this paper, laser additive manufacturing (LAM) technology with powder feeding has been employed to fabricate 50%LAMed specimens (i.e. the volume fraction of the laser deposited zone was set to 50%). With aid of the 3D-DIC technique, the tensile deformation behavior of 50%LAMed Ti64ELI titanium alloy was investigated. The 50%LAMed specimen exhibits a significant characteristic of strength mismatch due to the heterogeneous microstructure. The tensile fracture of 50%LAMed specimen occurs in WSZ (wrought substrate zone), but the tensile strength is slightly higher and the plastic elongation is significantly lower than that of the wrought specimen. The 3D-DIC results shows that the 50%LAMed specimen exhibits a characteristic of dramatic plastic strain heterogeneity and the maximal strain is invariably concentrated in WSZ. The ABAQUS simulation indicates that, the LDZ (laser deposited zone) can constrain the plastic deformation of the WSZ and biaxial stresses develop at the interface after yielding.

    A state of the art ellipsometer for user operations is being implemented at ELI Beamlines in Prague, Czech Republic. It combines three of the most promising and exotic forms of ellipsometry: VUV, pump-probe and magneto-optical ellipsometry. This new ellipsometer covers a spectral operational range from the NIR up to the VUV, with high through-put between 1 and 40 eV. The ellipsometer also allows measurements of magneto-optical spectra with a 1 kHz switchable magnetic field of up to 1.5 T across the sample combining ellipsometry and Kerr spectroscopy measurements in an unprecedented spectral range. This form of generalized ellipsometry enables users to address diagonal and off-diagonal components of the dielectric tensor within one measurement. Pump-probe measurements enable users to study the dynamic behaviour of the dielectric tensor in order to resolve the time-domain phenomena in the femto to 100 ns range.

    Full Text Available Direct metal laser sintering (DMLS is an additive manufacturing technology used to melt metal powder by high laser power to produce customised parts, light-weight structures, or other complex objects. During DMLS, powder is melted and solidified track-by-track and layer-by-layer; thus, building direction can influence the mechanical properties of DMLS parts. The mechanical properties and microstructure of material produced by DMLS can depend on the powder properties, process parameters, scanning strategy, and building geometry. In this study, the microstructure, tensile properties, and porosity of DMLS Ti6Al4V (ELI horizontal samples were analysed. Defect analysis by CT scans in pre-strained samples was used to detect the crack formation mechanism during tensile testing of as-built and heat-treated samples. The mechanical properties of the samples before and after stress relieving are discussed.

    There exists a translation gap between academic research and clinical practice in health care systems. One policy-driven initiative to address the translation gap in England are the Collaborations for Leadership in Applied Health Research and Care (CLAHRCs), funded by the National Institute of Health Research (NIHR). These aim to bring together NHS organizations and universities to accelerate the translation of evidence-based innovation into clinical practice. Our aim was to draw out lessons for policy-makers regarding the mobilization of such initiatives. Qualitative semi-structured interviews with 174 participants across nine CLAHRCs plus in-depth case studies across four CLAHRCs. Those interviewed were staff who were central to the CLAHRCs including senior managers and directors, junior and senior academics, and health care practitioners. Social positions of the CLAHRC leaders, conceived as institutional entrepreneurs, together with the antecedent conditions for CLAHRC bids, had an impact on the vision for a CLAHRC. The process of envisioning encompassed diagnostic and prognostic framing. Within the envisioning process, the utilization of existing activities and established relationships in the CLAHRC bid influenced early mobilization. However, in some cases, it led to a translational 'lock in' towards established models regarding applied research. The CLAHRC experiment in England holds important lessons for policy-makers regarding how to address the translation gap. First, policy makers need to consider whether they set out a defined template for translational initiatives or whether variation is encouraged. We might expect a degree of learning from pilot activities within a CLAHRC that allows for greater clarity in the design of subsequent translational initiatives. Second, policy makers and practitioners need to understand the importance of both antecedent conditions and the social position of senior members of a CLAHRC (institutional entrepreneurs) leading

    Laparoscopic suturing is an advanced skill that is difficult to acquire. Simulator-based skills curricula have been developed that have been shown to transfer to the operating room. Currently available skills curricula need to be optimized. We hypothesized that mastering basic laparoscopic skills first would shorten the learning curve of a more complex laparoscopic task and reduce resource requirements for the Fundamentals of Laparoscopic Surgery suturing curriculum. Medical students (n = 20) with no previous simulator experience were enrolled in an IRB-approved protocol, pretested on the Fundamentals of Laparoscopic Surgery suturing model, and randomized into 2 groups. Group I (n = 10) trained (unsupervised) until proficiency levels were achieved on 5 basic tasks; Group II (n = 10) received no basic training. Both groups then trained (supervised) on the Fundamentals of Laparoscopic Surgery suturing model until previously reported proficiency levels were achieved. Two weeks later, they were retested to evaluate their retention scores, training parameters, instruction requirements, and cost between groups using t-test. Baseline characteristics and performance were similar for both groups, and 9 of 10 subjects in each group achieved the proficiency levels. The initial performance on the simulator was better for Group I after basic skills training, and their suturing learning curve was shorter compared with Group II. In addition, Group I required less active instruction. Overall time required to finish the curriculum was similar for both groups; but the Group I training strategy cost less, with a savings of $148 per trainee. Teaching novices basic laparoscopic skills before a more complex laparoscopic task produces substantial cost savings. Additional studies are needed to assess the impact of such integrated curricula on ultimate educational benefit. Copyright (c) 2010 American College of Surgeons. Published by Elsevier Inc.

    2017-07-01

    The Global Polio Eradication Initiative has built an extensive infrastructure with capabilities and resources that should be transitioned to measles and rubella elimination efforts. Measles continues to be a major cause of child mortality globally, and rubella continues to be the leading infectious cause of birth defects. Measles and rubella eradication is feasible and cost saving. The obvious similarities in strategies between polio elimination and measles and rubella elimination include the use of an extensive surveillance and laboratory network, outbreak preparedness and response, extensive communications and social mobilization networks, and the need for periodic supplementary immunization activities. Polio staff and resources are already connected with those of measles and rubella, and transitioning existing capabilities to measles and rubella elimination efforts allows for optimized use of resources and the best opportunity to incorporate important lessons learned from polio eradication, and polio resources are concentrated in the countries with the highest burden of measles and rubella. Measles and rubella elimination strategies rely heavily on achieving and maintaining high vaccination coverage through the routine immunization activity infrastructure, thus creating synergies with immunization systems approaches, in what is termed a "diagonal approach." © The Author 2017.

    2014-12-01

    Full Text Available Despite the copious resources allocated by international development partners to enhance African countries’ capacity to evaluate the performance and impact of development programmes and policies, most evaluation capacity building (ECB efforts have not yielded the expected results. Time and energy have been focused on the measurement of short-term effects whilst long-term results have largely remained elusive. As a result, a variety of actors across the continent are calling for more innovative strategies. In particular, more efforts are currently being made to revitalise the evaluation function in international development at the global level and to enhance a shift from short-term training to more contextually relevant, systemic learning, equity and sustainability efforts. This article aims to provide a critical overview of ECB initiatives undertaken by international development partners in Africa over five years (2009–2014 that worked well and investigate how they could be improved. The common issues stress the need for harmonisation and collaboration between international partners and African institutions and more effective collaboration with in country institutions and organisations committed to evaluation capacity development (ECD. The analysis in this article is timely and relevant for both the strengthening of socalled made-in Africa evaluation methods and approaches and the roll-out of systemic and organic ECD strategies. The debate spurred by this article is likely to contribute to the current global debate on what strategies ought to be taken as part of the post-2015 agenda. This inturn will spur the debate on ECD to increase in importance and undoubtedly in intensity.

  15. Detection of Convective Initiation Using Meteorological Imager Onboard Communication, Ocean, and Meteorological Satellite Based on Machine Learning Approaches

    Full Text Available As convective clouds in Northeast Asia are accompanied by various hazards related with heavy rainfall and thunderstorms, it is very important to detect convective initiation (CI in the region in order to mitigate damage by such hazards. In this study, a novel approach for CI detection using images from Meteorological Imager (MI, a payload of the Communication, Ocean, and Meteorological Satellite (COMS, was developed by improving the criteria of the interest fields of Rapidly Developing Cumulus Areas (RDCA derivation algorithm, an official CI detection algorithm for Multi-functional Transport SATellite-2 (MTSAT-2, based on three machine learning approaches—decision trees (DT, random forest (RF, and support vector machines (SVM. CI was defined as clouds within a 16 × 16 km window with the first detection of lightning occurrence at the center. A total of nine interest fields derived from visible, water vapor, and two thermal infrared images of MI obtained 15–75 min before the lightning occurrence were used as input variables for CI detection. RF produced slightly higher performance (probability of detection (POD of 75.5% and false alarm rate (FAR of 46.2% than DT (POD of 70.7% and FAR of 46.6% for detection of CI caused by migrating frontal cyclones and unstable atmosphere. SVM resulted in relatively poor performance with very high FAR ~83.3%. The averaged lead times of CI detection based on the DT and RF models were 36.8 and 37.7 min, respectively. This implies that CI over Northeast Asia can be forecasted ~30–45 min in advance using COMS MI data.

    2017-12-01

    The formation of PEO ceramic coatings on Ti6Al4V ELI alloy was investigated using a phosphate/calcium containing electrolyte at 300 and 400V at 310K for different times. The Plasma Electrolytic Oxidation (PEO) coated specimens were then heat treated at 873 and 1073K for 2 hours. Scanning electron microscopy, Energy Dispersive X-Ray Spectroscopy (EDS) and X-ray diffraction analysis were used to study the composition and the morphology of the ceramic coatings. The corrosion behaviour of the coatings was studied by Electrochemical Impedance Spectroscopy (EIS) in Simulated Body Fluid (SBF). The PEO-treated specimens primarily revealed a porous structure with thickness between 4 and 12μm, according to the voltage and process time used. The coatings are mainly composed of hydroxyapatite; however, as the voltage and anodizing time increase, the Ca/P ratio decreases. Generally, the corrosion resistance of the alloy was improved by the PEO-treated coatings, although the specimens treated at 1073K showed the presence of cracks that reduced the protective effect of the coatings.

    Lieve Jooken

    2018-01-01

    Full Text Available Early into his career as one of the most successful printerpublishers of the Dutch Republic, Elie Luzac (1721-1796 played a pivotal role in disseminating the materialist ideas of La Mettrie’s Homme machine (1747. This paper focuses on the dialogic voice (Bakhtine in a publication by Luzac himself, which oscillates between asserting and refuting La Mettrie’s views. Descended from Huguenot refugees, Luzac condemns what he publishes and publishes what he condemns. This discursive ambiguity emerges in Luzac’s L’homme plus que machine (1748, a work which cites La Mettrie’s theses in order to contest them. Building on the succès de scandale of the English version of L’homme machine (Man a Machine, 1749, the English translation of L’homme plus que machine, Man more than a Machine, appeared in 1752. The present contribution examines how the translator’s Voice, which is defined as an enarrative voice, effaces the concealed claims of the original text and replaces them with a discourse whose explicit anti-materialist tenor contrasts with the vehement rhetoric of Man a Machine.

  5. Analysis of surface roughness and cutting force during turning of Ti6Al4V ELI in dry environment

    2016-04-01

    Full Text Available This paper investigates the effect of cutting parameters on the surface roughness and cutting force of titanium alloy Ti-6Al-4V ELI when turning using PVD TiAlN coated tool in dry environment. Taguchi L9 orthogonal array design of experiment was used for the turning experiment 2 factors and 3 levels. Turning parameters studied were cutting speed (50, 65, 80 m/min, feed rate (0.08, 0.15, 0.2 mm/rev and depth of cut 0.5 mm constant. Linear and second order model of the surface roughness and cutting force has been developed in terms of cutting speed and feed. The results show that the feed rate was the most impact factor controlling the cutting force and surface roughness produced. MINITAB 17software was used to develop a linear and second order model of surface roughness and cutting force. Optimum condition was at 66.97 m/min of cutting speed, 0.08 mm/rev of feed rate. Surface roughness 0.57μm and cutting force 54.02 N were obtained at the optimum condition. A good agreement between the experimental and predicted surface roughness and cutting force were observed.

    The Extreme Light Infrastructure - Nuclear Physics (ELI-NP) is under construction in Magurele, Bucharest, Romania. The facility will use two 10 PW lasers and a high intensity, narrow bandwidth gamma beam for stand-alone and combined laser-gamma experiments. The accurate estimation of particle doses and their restriction within the limits for both personel and general public is very important in the design phase of any nuclear facility. In the present work, Monte Carlo simulations are performed using FLUKA and MCNPX to design 19.4 and 4 MeV gamma beam dumps along with shielding of experimental areas. Dose rate contour plots from both FLUKA and MCNPX along with numerical values of doses in experimental area E8 of the facility are performed. The calculated doses are within the permissible limits. Furthermore, a reasonable agreement between both codes enhances our confidence in using one or both of them for future calculations in beam dump designs, radiation shielding, radioactive inventory, and other calculations releated to radiation protection. Residual dose rates and residual activity calculations are also performed for high-energy beam dump and their effect is negligible in comparison to contributions from prompt radiation.

    1978-01-01

    The method of polarized orbitals is modified to treat low-energy scattering of electrons from highly polarizable systems, specifically alkali-metal atoms. The modification is carried out in the particular context of the e-Li system, but the procedure is general; it consists of modifying the polarized orbital, so that when used in the otherwise orthodox form of the method, it gives (i) the correct electron affinity of the negative ion (in this case Li - ), (ii) the proper (i.e., Levinson-Swan) number of nodes of the associated zero-energy scattering orbital, and (iii) the correct polarizability. A procedure is devised whereby the scattering length can be calculated from the (known) electron affinity without solving the bound-state equation. Using this procedure we adduce a 1 S scattering length of 8.69a 0 . (The 3 S scattering length is -9.22a 0 .) The above modifications can also be carried out in the (lesser) exchange adiabatic approximation. However, they lead to qualitatively incorrect 3 S phase shifts. The modified polarized-orbital phase shifts are qualitatively similar to close-coupling and elaborate variational calculations. Quantitative differences from the latter calculations, however, remain; they are manifested most noticeably in the very-low-energy total and differential spin-flip cross sections

    An airborne combined radiometric and magnetic survey was performed for the Department of Energy (DOE) over the area covered by the Ely and Lund 1:250,000 National Topographic Map Series (NTMS quadrangle maps). The survey was part of DOE's National Uranium Resource Evaluation (NURE) Aerial Radiometric Reconnaissance program. Data were collected by a helicopter equipped with a gamma-ray spectrometer having a large crystal volume, and a high sensitivity proton precession magnetometer. The radiometric system was calibrated at the Walker Field Calibration pads and the Lake Mead Dynamic Test range. Data quality was ensured during the survey by daily test flights and equipment checks. Radiometric data were corrected for live time, aircraft and equipment background, cosmic background, atmospheric radon, Compton scatter, and altitude dependence. The corrected data were statistically evaluated, plotted, and contoured to produce anomaly maps based on the radiometric response of individual geological units. The maps were interpreted and an anomaly interpretation map produced. Volume I contains a description of the systems used in the survey, a discussion of the calibration of the systems, the data processing procedures, the data display format, the interpretation rationale, and interpretation methodology. Volume II contains the data displays for a quadrangle and the interpretation results

    To investigate residents' self-reported satisfaction level with their proficiency in extracapsular cataract extraction (ECCE) surgery and the initial barriers to learning the procedure. This is a single-centre prospective descriptive case series involving eight first-year ophthalmology residents in Singapore National Eye Center. We recorded the demographics, frequency of review by the residents of their own surgical videos and their satisfaction level with their proficiency at each of the ECCE steps using a 5-point Likert scale. All ECCE surgical videos between October 2013 and May 2014 were collected and analysed for the overall time taken for the surgery and the time taken to perform the individual steps of the procedure. The mean age of the residents was 27.6 ± 1.5 years and 62.5% (5/8) were women. More than half (62.5%, 5/8) reviewed their own surgical videos while 37.5% (3/8) discussed the surgical videos with their peers or supervisors. Of the ECCE steps, the residents were most dissatisfied with their proficiency in performing irrigation and aspiration (87.5%, 7/8), followed by suturing (62.5%, 5/8), intraocular lens insertion (62.5%, 5/8) and tin can capsulotomy (62.5%, 5/8). The average time taken for each ECCE case was 55.0 ± 12.2 min and, of all the steps, most time was spent on suturing (20.5 ± 6.8 min), followed by irrigation and aspiration (5.5 ± 3.6 min) and tin can capsulotomy (3.3 ± 1.8 min). The first-year ophthalmology residents were most dissatisfied with their proficiency in irrigation/aspiration, suturing and tin can capsulotomy. More training needs to be directed to these areas during teaching sessions in the operating room, wet laboratory or cataract simulation training sessions.

    To use errorless learning to train a memory- and initiation-impaired woman on two activities of daily living routines and then to transfer these routines to a new home. Single case quasi-experimental. Over 9 months, a young woman with an anterior cerebral haemorrhagic stroke (secondary to a ruptured arteriovenous malformation) was trained on routines of morning self-care and diabetes management, involving extensive practice on a structured series of steps with intervention as needed to prevent errors. Once routines were established, family members were trained in the supervision and rating of the routines at home. Following discharge, caregivers continued to monitor the routines daily for 3 months. Errorless learning of self-care and diabetes routines was successful. The routines were transferred to a new home environment and maintained at a near perfect level over a 3-month follow-up period. The patient remained severely memory-impaired, indicating that her functional gains were not attributable to any recovery of her memory abilities over time. This case offers evidence that even people with severe memory and initiation impairments can be trained on new routines using errorless learning and that, once learned, these routines can be carried out in novel contexts.

    Full Text Available Abstract Background In November 2002, the Centers for Medicare & Medicaid Services (CMS launched a Nursing Home Quality Initiative that included publicly reporting a set of Quality Measures for all nursing homes in the country, and providing quality improvement assistance to nursing homes nationwide. A pilot of this initiative occurred in six states for six months prior to the launch. Methods Review and analysis of the lessons learned from the six Quality Improvement Organizations (QIOs that led quality improvement efforts in nursing homes from the six pilot states. Results QIOs in the six pilot states found several key outcomes of the Nursing Home Quality Initiative that help to maximize the potential of public reporting to leverage effective improvement in nursing home quality of care. First, public reporting focuses the attention of all stakeholders in the nursing home industry on achieving good quality outcomes on a defined set of measures, and creates an incentive for partnership formation. Second, publicly reported quality measures motivate nursing home providers to improve in certain key clinical areas, and in particular to seek out new ways of changing processes of care, such as engaging physicians and the medical director more directly. Third, the lessons learned by QIOs in the pilot of this Initiative indicate that certain approaches to providing quality improvement assistance are key to guiding nursing home providers' desire and enthusiasm to improve towards a using a systematic approach to quality improvement. Conclusion The Nursing Home Quality Initiative has already demonstrated the potential of public reporting to foster collaboration and coordination among nursing home stakeholders and to heighten interest of nursing homes in quality improvement techniques. The lessons learned from this pilot project have implications for any organizations or individuals planning quality improvement projects in the nursing home setting.

    South Africa desperately needs a comprehensive approach to fight HIV/AIDS. Education is crucial to reach this goal and Internet and e-learning could offer huge opportunities to broaden and deepen the knowledge basis. But due to the huge societal and digital divide between rich and poor areas, e-learning is difficult to realize in the townships. Community health workers often act as mediators and coaches for people seeking medical and personal help. They could give good advice regarding hygiene, nutrition, protection of family members in case of HIV/AIDS and finding legal ways to earn one's living if they were trained to do so. Therefore they need to have a broader general knowledge. Since learning opportunities in the townships are scarce, a system for e-learning has to be created in order to overcome the lack of experience with computers or the Internet and to enable them to implement a network of expertise. The article describes how the best international resources on basic medical knowledge, HIV/AIDS as well as on basic economic and entrepreneurial skills were benchmarked to be integrated into an e-learning system. After tests with community health workers, researchers developed recommendations on building a self-sustaining system for learning, including a network of expertise and best practice sharing. The article explains the opportunities and challenges for community health workers, which could provide information for other parts of the world with similar preconditions of rural poverty. © The Author(s) 2015.

    Learning digital games can influence both older adults' health condition and their capacity to carry on activities in their actual environment. The goal of the current study was to explore and define the user requirements for developing digital learning games for older Europeans, focusing on types of learning games, motivational and social aspects, and preferences on game controllers. For this initial stage, a qualitative focus group study was performed in three participating countries (Spain, The Netherlands, and Greece) where both games existing in the market and others developed in other European Commission projects like HERMES were presented to them, both on video presentations and also with the possibility to actually test some of them. Challenge, socialization, fun, providing learning opportunities, and escape from daily routine were extracted as the main keys why older people would be interested in playing digital games. Users described themselves as active and participating in many leisure activities, and this level of activity appeared to be related with the contents proposed for digital games, such as physical activity, culture, arts, and other human sciences (history, geography, traveling, foreign languages, music), and daily life skills (cooking, computer use, first aid). The knowledge gathered from the focus groups will be used as input for the design of a learning game that will be largely compatible with the needs and abilities of a wide range of older Europeans.

    Full Text Available Western influence on the Middle East is a theme that deservedly attracts attention of many scientists from various fields of study. Many theories with regard to the modern political history of the region have been produced and discussed. One of the authors that came out with an influential concept was Edward Said. In his critique of Orientalism (Orientalism, 1978, Said focuses on Western conceptions of the Middle East and its outcomes. The book became worldwide famous for its direct assault on Western society and its imperial politics. An influential attitude is taken by another prominent scientist, Bernard Lewis, who represents an opposition to Said´s opinion. This survey is geared towards presenting the work of Baghdad-born British historian Elie Kedourie, who maintains with regard to given topic very interesting position as well. In the course of his career Kedourie mainly focused on modern Middle Eastern history, with a consideration to British political influence in the region. Kedourie tried to analyse factors which brought Ottoman Empire to decline and Middle Eastern region to general long-lasting crisis. In his writings Kedourie questioned the matter of suitability of Ottoman reforms based on European examples. He also occupied himself in detail with the issue of McMahon-Husayn correspondence and its interpretations, as well as with the Sykes-Picot agreement. He polemised with official viewpoints of British establishment and, usually with criticism, he assessed measures of British foreign politics. His revolutionary interpretations are believed to have changed the scientific approach of the view on modern history of the Middle Eastern countries.

    ELI-NP will be a new international research infrastructure facility for laser-based Nuclear Physics to be built in Magurele, south west of Bucharest, Romania. For the machine to operate as an intense γ rays' source based on Compton back-scattering, electron beams are employed, undergoing a two stage acceleration to 320 MeV and 740 MeV (and, with an eventual energy upgrade, also to 840 MeV) beam energies. In order to assess the radiation safety issues, concerning the effectiveness of the dumps in absorbing the primary electron beams, the generated prompt radiation field and the residual dose rates coming from the activation of constituent materials, as well as the shielding of the adjacent environments against both prompt and residual radiation fields, an extensive design study by means of Monte Carlo simulations with FLUKA code was performed, for both low energy 320 MeV and high energy 720 MeV (840 MeV) beam dumps. For the low energy dump we discuss also the rational of the choice to place it in the building basement, instead of installing it in one of the shielding wall at the machine level, as it was originally conceived. Ambient dose equivalent rate constraints, according to the Rumenian law in force in radiation protection matter were 0.1 /iSv/h everywhere outside the shielding walls and 1.4 μiSv/h outside the high energy dump area. The dumps' placements and layouts are shown to be fully compliant with the dose constraints and environmental impact.

    The technologies associated with distance learning are evolving rapidly, giving to educators a potential tool for enhancing the educational experiences of large numbers of students simultaneously. This enhancement, in order to be effective, must take into account the various agendas of teachers, administrators, state systems, and of course students. It must also make use of the latest research on effective pedagogy. This combination, effective pedagogy and robust information technology, is a powerful vehicle for communicating, to a large audience of school children the excitement of mathematics and science--an excitement that for the most part is now well-hidden. This project,"Technology Development, Implementation and Assessment," proposed to bring to bear on the education of learners in grades 3 - 8 in science and mathematics both advances in information technology and in effective pedagogy. Specifically, the project developed components NASA CONNECT video series--problem-based learning modules that focus on the scientific method and that incorporate problem-based learning scenarios tied to national mathematics and science standards. These videos serve two purposes; they engage students in the excitement of hands-on learning and they model for the teachers of these students the problem-based learning practices that are proving to be excellent ways to teach science and mathematics to school students. Another component of NASA CONNECT is the accompanying web-site.

    In many communities, children learn about family and community endeavors as they collaborate and become involved in community activities. This chapter analyzes how parents promote collaboration and learning to collaborate at home in an Indigenous and in a non-Indigenous Mexican community. We examine variation among parents with different extent of experience with schooling and concepts regarding child development and relate these to patterns of child collaboration at home among Mexican Indigenous and urban families. Drawing on interviews with 34 mothers in the P'urhépecha community of Cherán, Michoacán, and 18 interviews in the cosmopolitan city of Guadalajara, Mexico, we argue that the social nature of participation may be a key feature of learning to collaborate and pitch in in families and communities where school has not been a central institution of childhood over generations. © 2015 Elsevier Inc.

    One of the National Oceanic and Atmospheric Administration (NOAA) goals is to provide timely and reliable weather forecasts to support important decisions when and where people need it for safety, emergencies, planning for day-to-day activities. Satellite data is essential for areas lacking in-situ observations for use as initial conditions in Numerical Weather Prediction (NWP) Models, such as spans of the ocean or remote areas of land. Currently only about 7% of total received satellite data is selected for use and from that, an even smaller percentage ever are assimilated into NWP models. With machine learning, the computational and time costs needed for satellite data selection can be greatly reduced. We study various machine learning approaches to process orders of magnitude more satellite data in significantly less time allowing for a greater quantity and more intelligent selection of data to be used for assimilation purposes. Given the future launches of satellites in the upcoming years, machine learning is capable of being applied for better selection of Regions of Interest (ROI) in the magnitudes more of satellite data that will be received. This paper discusses the background of machine learning methods as applied to weather forecasting and the challenges of creating a "labeled dataset" for training and testing purposes. In the training stage of supervised machine learning, labeled data are important to identify a ROI as either true or false so that the model knows what signatures in satellite data to identify. Authors have selected cyclones, including tropical cyclones and mid-latitude lows, as ROI for their machine learning purposes and created a labeled dataset of true or false for ROI from Global Forecast System (GFS) reanalysis data. A dataset like this does not yet exist and given the need for a high quantity of samples, is was decided this was best done with automation. This process was done by developing a program similar to the National Center for

  10. Predator odor avoidance as a rodent model of anxiety: learning-mediated consequences beyond the initial exposure.

    Science.gov (United States)

    Staples, Lauren G

    2010-11-01

    Prey animals such as rats display innate defensive responses when exposed to the odor of a predator, providing a valuable means of studying the neurobiology of anxiety. While the unconditioned behavioral and neural responses to a single predator odor exposure have been well documented, the paradigm can also be used to study learning-dependent adaptations that occur following repeated exposure to a stressor or associated stimuli. In developing preclinical models for human anxiety disorders this is advantageous, as anxiety disorders seldom involve a single acute experience of anxiety, but rather are chronic and/or recurring illnesses. Part 1 of this review summarizes current research on the three most commonly used predator-related odors: cat odor, ferret odor, and trimethylthiazoline (a component of fox odor). Part 2 reviews the learning-based behavioral and neural adaptations that underlie predator odor-induced context conditioning, one-trial tolerance, sensitization, habituation and dishabituation.

    This paper examines the social thought of University of Wisconsin professors Richard T. Ely, John R. Commons, and Edward A. Ross during World War I. Like many of their fellow scholars, these three were actively involved in the pro-war effort. Although their support for the war was strongly conditioned by personal and occupational considerations, the impact of their wartime service was not restricted to those realms. Their social thought, which they impressed into service explaining and justifying the war, was itself altered in subtle and sometimes surprising ways by the forceful positions they took on the political, economic, and racial significance of the conflict.

    2015-01-01

    The topic of debriefing has been receiving some attention in the simulation literature. Because of the significance of debriefing on learning, evaluation of the de-briefer is done to ensure optimal performance. Structured debriefing as a learning tool was evaluated at the end of modular teaching of first year MBBS. This study is a descriptive cross sectional study to analyze the usefulness of debriefing as an instructional strategy during observed structured clinical examination conducted at the end of two consecutive modules of first year MBBS students. Methods: Performance of 150 students of first year MBBS was evaluated at the end of modules called Foundation module and skin and musculoskeletal module. Debriefing was structured and conducted after training of six staff members who conducted and supervised Objectively Structured Clinical Examination. Results: Apart from description of results of Objectively Structured Clinical Examination that were generally good, students praised the debriefing session. Ninety percent students thought the timing of debriefing to be perfect. Only 2% percent students complained about negative debriefing. Ten percent students wanted the debriefing session to be conducted in camera so that they could evaluate their own performance. Conclusion: Debriefing session at the end of modular teaching Objectively Structured Clinical Examination is a useful learning tool as not only it provides immediate feedback about the performance but gives students opportunity to discuss own performance with the instructor in order to develop habit of lifelong self-directed adult learner.

    2002-08-01

    Duloxetine is a serotonin (5-HT) and norepinephrine (NE) uptake inhibitor in pre-registration for depression. In vivo studies demonstrate that duloxetine inhibits 5-HT and NE transporters and this may induce an antidepressant effect [159168]. In humans, duloxetine has a low affinity for most 5-HT subtypes and for muscarinic, histamine H1, alpha1-adrenergic, alpha2-adrenergic and dopamine D2 receptors [444103]. Thus, it is not surprising that the meta-analysis of four recent clinical studies suggests duloxetine is a potent and well-tolerated antidepressant [429723]. By December 2001, Lilly had filed an NDA for depression. The launch of duloxetine is planned for the second half of 2002 [434250], [436220]. In April 2002, filing for stress urinary incontinence was anticipated for later in 2002 [456894]. Analysts at Banc of America predicted in April 2002, that the drug will be launched in the first quarter of 2003. The company projects US $400 million in revenue in 2003 and anticipates duloxetine to reach peak sales of over US $1 billion [450920]. Analysts at Morgan Stanley, projected US $25 million in sales in the fourth quarter 2002, rising to US $900 million in 2006 [450937]. At the same time, Credit Suisse First Boston anticipated launch for late 2002, with US $220 million in duloxetine revenues in 2003 and US $457 million in 2004 [450936].

    Lilly is developing duloxetine, a 5-HT and norepinephrine uptake inhibitor as a potential treatment for depression and urinary incontinence. In Japan, it is being jointly developed with Shionogi [187401]. Phase III trials for depression and phase II trials for urinary incontinence are underway in Japan [296442,328887]. Lilly expects to file for depression in 2002 and phase III trials for urinary incontinence are planned to start enrollment by the end of 2000 [358429,370526,373870]. Duloxetine has a half-life of 10 to 15 h in humans, and parameters reach a steady-state after 3 days of daily administration. In a 6-week, open-label study duloxetine was safe and well tolerated in 79 clinically depressed patients. Clinical response occurred in 78% of patients, and remission occurred in 60%. Insomnia and nausea occurred with an incidence of 20% [300881]. Duloxetine may offer advantages over existing antidepressants, such as Lilly's fluoxetine, because of faster recovery and fewer side effects [190226]. In June 2000, Morgan Stanley Dean Witter predicted duloxetine would reach the market in 2002 with annual sales in this year of US $50 million, rising to $200 million in 2005 [373870]. In February 1999, Deutsche Bank predicted Lilly's sales at US $200 million in 2002 rising to $400 million in 2003 [316821]. In May 2000, Deutsche Bank had made further predictions, stating that filing for duloxetine is expected in the fourth quarter of 2001, and peak sales are expected to exceed US $500 million. Also in February 1999, Lehman Brothers predicted the first major launch date (US and ex-US) to be 2002, with the year of peak sales to be 2008 [319225]. In August 1999, this prediction changed, and the expected launch date became 2001, with an 80% probability of reaching the market and sales peaking at US $150 million in 2012 [349228].

In this section, academics, policy-makers and practioners engage in a dialogue on global development challenges. Papers are copy-edited but not peer-reviewed. Instead, the initial thematic contribution is followed by critical comments and reactions from scholars and/or policy-makers.In her article ‘Pay to Preserve: The Global Politics of Ecuador’s Yasuní-ITT Proposal’, published in DevPol’s special issue on  Energy and Development in 2011, Pamela L. Martin, Associate Professor of Politics at the Coastal Carolina University in Conway, South Carolina, provided a favourable outlook on Ecuador’s innovative environmental governance mechanism. Accordingly, its unique potential lay in its objective of contributing towards sustainable development and social justice and in case of success, the author even predicted a possible replication in other developing countries. Despite its benefits, the initiative was abandoned in 2013. In this paper, Martin revisits the initiative and analyses the reasons for its failure, namely President Correa’s public pursuit of a Plan B, entering into negotiations with oil firms interested to explore the ITT reserves. Moreover, the initiative was in stark competition with the national REDD+ programme, the mainstream policy approach to reduce emissions from deforestation and forest degradation against payments, which is being negotiated under the United Nations Framework Convention on Climate Change (UNFCCC.Pamela L.

    Full Text Available Significant investments are being made in the application of new information and communications technologies (ICT to teaching and learning in higher education. However, until recently, there has been little progress in devising an integrated costbenefit model that decision-makers can use to appraise ICT investment options from the wider institutional perspective. This paper describes and illustrates a model that has been developed to enable evaluations of the costs and benefits of the use of ICT. The strengths and limitations of the model are highlighted and discussed

    Foundation for Advancement of International Medical Education and Research (FAIMER) faculty development programs have operated since 2001 and are designed to overcome many of the challenges inherent in global health collaborations, including alignment with local needs, avoiding persistent dependency, and development of trust. FAIMER fellowship programs, developed for midcareer faculty members in all health professions from around the world, share goals of strengthening knowledge and skills in education leadership, education methods, and project management and evaluation. Building community is another explicit goal that allows participants to support and learn from each other.The author recommends several practices for successful international collaborations based on 13 years of experience with FAIMER fellowships. These include using authentic education projects to maintain alignment with local needs and apply newly acquired knowledge and skills, teaching leadership across cultures with careful communication and adaptation of concepts to local environments, cultivating a strong field of health professions education to promote diffusion of ideas and advocate for policy change, intentionally promoting field development and leadership to reduce dependency, giving generously of time and resources, learning from others as much as teaching others, and recognizing that effective partnerships revolve around personal relationships to build trust. These strategies have enabled the FAIMER fellowship programs to stay aligned with local needs, reduce dependency, and maintain trust.

    We reported 19 cases of school-aged children. They were initially judged to have learning difficulty or school maladaptation because of attention deficits, hyperactive behaviors or poor school performance, followed by the diagnosis such as degenerative or metabolic neurological diseases. The patients consisted of 4 cases of adrenoleukodystrophy, 5 cases of dentatorubral-pallidoluysian atrophy, 3 cases of Sanfilippo syndrome, 3 cases of subacute sclerosing panencephalitis, and each one case of juvenile Gaucher disease, juvenile Huntington disease, juvenile metachromatic leukodystrophy and Leigh disease. They had markedly poor school performance, and/or abnormal behaviors, followed by seizures, character disorders or psychomotor regression. The diagnostic clues included brain CT scan and/or MRI, peculiar facial appearance and notable family histories. When the children were indicated to have learning difficulty or maladjustment to school life, we should make deliberate differential diagnoses before concluding that they have a learning disorder and/or attention-deficit/hyperactivity disorder. Instead they should be recommended to visit child neurologists, when they present with any problems as aforesaid.

    Increasing the laser-induced damage resistance of optical components is one of the major challenges in the development of Peta-watt (PW) class laser systems. The extreme light infrastructure (ELI) beamlines project will provide ultrafast laser systems with peak powers up to 10 PW available every minute and PW class beams at 10 Hz complemented by a 5-TW, 1-kHz beamline. Sustainable performance of PW class laser systems relies on the durability of the employed optical components. As part of an effort to evaluate the damage resistance of components utilized in ELI beamlines systems, damage thresholds of several optical multilayer dielectric coatings were measured with different laser parameters and in different environments. Three coatings were tested with 10 Hz and 1 kHz pulse repetition rates, and the effect of a cleaning treatment on their damage resistance was examined. To explore the damage threshold behavior at different vacuum levels, one coating was subject to tests at various residual gas pressures. No change of damage threshold in a high vacuum with respect to ambient pressure was recorded. The effect of the cleaning treatment was found to be inconsistent, suggesting that development of the optimal cleaning treatment for a given coating requires consideration of its specific properties.

    As in other countries of the Greater Mekong Sub-region (GMS), the private health sector constitutes a significant avenue where malaria services are provided and presents a unique opportunity for public-private collaboration. In September 2008, a public-private mix (PPM) strategy was launched initially in four northern and southern provinces in Lao PDR to increase access to rapid diagnostic tests (RDTs) and artemisinin-based combination therapy (ACT), improve quality of care, and collect routine malaria data from the private sector. Throughout the process, key stakeholders were involved in the planning, monitoring and supervision of project sites. Following an initial assessment in 2009, the PPM initiative expanded to an additional 14 district sites to a total of 245 private pharmacies and 16 clinics covering 8 provinces and 22 districts. By June 2016, a total of 317 pharmacies, 30 clinics in 32 districts of the 8 provinces were participating in the PPM network and reported monthly malaria case data. This descriptive study documented the process of initiating and maintaining the PPM network in Lao PDR. Epidemiological data reported through the routine surveillance system from January 2009 to June 2016 were analyzed to illustrate the contribution of case reporting from the private sector. A total of 2,301,676 malaria tests were performed in the PPM districts, which included all the PPM pharmacies and clinics (176,224, 7.7%), proportion of patients tested from 14,102 (4.6%) in 2009 to 29,554 (10.4%) in 2015. Over the same period of 90 months, a total of 246,091 positive cases (10.7%) were detected in PPM pharmacies and clinics (33,565; 13.6%), in the same districts as the PPM sites. The results suggest that the PPM sites contributed to a significant increasing proportion of patients positive for malaria from 1687 (7.4%) in 2009 to 5697 (15.8%) in 2015. Ensuring adequate and timely supplies of RDTs and ACT to PPM sites is critical. Frequent refresher training is

    Worldwide interest in problem-based learning (PBL) has grown in past decades. This article aims to evaluate the perceived effectiveness, appropriateness, benefits, and challenges attributed to the use of PBL in public health education in Vietnam with a view to providing recommendations for curricular design and future policy. Teachers at 2 universities in Hanoi participated in group interviews, and students from these 2 universities completed Likert-style questionnaires. Students and teachers regarded PBL positively. However, there was consensus that hybrid models that used PBL alongside other methods are probably the most beneficial for public health education in Vietnam. Teachers discussed the educational and systematic advantages and difficulties associated with PBL. Themes arising from this analysis may be helpful in guiding future research-namely, regarding the application of PBL in low- and middle-income countries and in public health. Further exploration of the use of PBL hybrid models is discussed. © 2012 APJPH.

    Although many outstanding achievements in the management of cervical cancer (CxCa) have obtained, it still imposes a major burden which has prompted scientists to discover and validate new CxCa biomarkers to improve the diagnostic and prognostic assessment of CxCa. In this study, eight different gene expression data sets containing 202 cancer, 115 cervical intraepithelial neoplasia (CIN), and 105 normal samples were utilized for an integrative systems biology assessment in a multi-stage carcinogenesis manner. Deep learning-based diagnostic models were established based on the genetic panels of intrinsic genes of cervical carcinogenesis as well as on the unbiased variable selection approach. Survival analysis was also conducted to explore the potential biomarker candidates for prognostic assessment. Our results showed that cell cycle, RNA transport, mRNA surveillance, and one carbon pool by folate were the key regulatory mechanisms involved in the initiation, progression, and metastasis of CxCa. Various genetic panels combined with machine learning algorithms successfully differentiated CxCa from CIN and normalcy in cross-study normalized data sets. In particular, the 168-gene deep learning model for the differentiation of cancer from normalcy achieved an externally validated accuracy of 97.96% (99.01% sensitivity and 95.65% specificity). Survival analysis revealed that ZNF281 and EPHB6 were the two most promising prognostic genetic markers for CxCa among others. Our findings open new opportunities to enhance current understanding of the characteristics of CxCa pathobiology. In addition, the combination of transcriptomics-based signatures and deep learning classification may become an important approach to improve CxCa diagnosis and management in clinical practice.

    Global health education and health promotion have the potential to engage students, scholars, and practitioners in ways that go beyond the classroom teaching routine. This engagement in global communities, can range from reflection on continuing deep-seated questions about human rights and civic responsibility to the use of health education and promotion-related theoretical, intellectual, and practical skills. In the arena of global health education and promotion, these skills also range from leadership and advocacy to decision making, critical and creative thinking, teamwork, and problem solving. In recent times, there has been a growing interest in cross-cultural collaborations and educational initiatives to improve stakeholder's understanding of global health principles and practices, to enrich the experiences of health professionals, and to improve the lives of those who are disenfranchised and live across borders. In this article of Health Promotion Practice, we highlight two unique cases of cross-national collaborations and provide a glimpse of the various shapes and forms taken by cross-cultural educational initiatives for global health education and promotion. We summarize the history, philosophy, and current working practices relevant to these collaborations, keeping in view the global health domains, competencies, and activities. In addition, we also compare the key components and activities of these two case studies from Rwanda and Mexico, wherein communities in these two countries collaborated with academic institutions and health professionals in the United States.

    Full text: Regulatory inspection and law enforcement are among the core competencies of the Indonesia Nuclear Energy Regulatory Agency (BAPETEN). Knowledge management (KM) initiatives are based on strategic planning of BAPETEN. KM in BAPETEN is in its early stage, it is realized since 2015–2016, although its elements have stayed in service for 18 years. Its architecture and performance-information are: to conduct risk based inspection for medical, industrial and research facilities; to plan, monitor and evaluate of effective inspection, including standard operating procedures (SOPs); to utilize inspectors for safety security of radiation sources along with coordination with related stakeholders; to enforce the safety and security facilities report to users; to optimize reliable data communication, processing and information technology (B@LIS); to perform regulatory enforcement along with other related stakeholders. KM processes are performed through the “Socialization, Externalization, Combination, Internalization” (SECI) model. Technical knowledge for inspectors are based on the IAEA–TECDOC–1526 plus supporting knowledge. With KM, innovation products can easily be used, because they are documented, distributed in a KM portal, knowledge is shared through the BAPETEN website, B@LIS database and others. Our challenge is that KM initiatives still need a tremendous effort, not only internally, but also externally, especially in coordination and collaboration. Information access brings about not only positive but also negative impacts. Innovations in regulatory inspection and law enforcement in BAPETEN are planned innovations, sustained, and systematically performed. (author

    Full Text Available Objective. We aimed to compare the results of our initial robot-assisted nephron-sparing surgeries (RANSS performed with or without hilar clamping. Material and Method. Charts of the initial RANSSs (n=44, which were performed by a single surgeon, were retrospectively reviewed. R.E.N.A.L. nephrometry system, modified Clavien classification, and M.D.R.D. equation were used to record tumoral complexity, complications, and estimated glomerular filtration rate (eGFR, respectively. Outcomes of the clamped (group 1, n=14 versus off-clamp (group 2, n=30 RANSSs were compared. Results. The difference between the two groups was insignificant regarding mean patient age, mean tumor size, and mean R.E.N.A.L. nephrometry score. Mean operative time, mean estimated blood loss amount, and mean length of hospitalization were similar between groups. A total of 4 patients in each group suffered 11 Clavien grade ≥2 complications early postoperatively. Open conversion rates were similar. The difference between the 2 groups in terms of the mean postoperative change in eGFR was insignificant. We did not encounter any local recurrence after a mean follow-up of 18.9 months. Conclusions. Creating warm-ischemic conditions during RANSS should not be a liberal decision, even in the initial phases of the learning curve for a highly experienced open surgeon.

    This summer 22 kindergarten through 8th grade teachers attended a 3-week Teacher Enhancement Institute (TEI) at NASA Langley Research Center. TEI is funded by NASA Education Division and is a collaborative effort between NASA Langley's Office of Education and Christopher Newport University. Selected teacher teams were drawn from Langley's 5-state precollege service region, which includes Kentucky, North Carolina, South Carolina, Virginia, and West Virginia. The goal of TEI was for teachers to learn aeronautics and the broad application of science and technology through a problem-based learning (PBL) strategy. PBL is an instructional method using a real world problem, also known as an ill-structured problem, as the context for an in-depth investigation. Most real life problems are ill-structured, as are all the really important social, political and scientific problems. The teachers were immediately immersed in an ill-structured problem to design a communication strategy for the White House Commission on Aviation Safety and Security to educate and disseminate aviation information to the general public. Specifically, the communication strategy was to focus on aeronautics principles, technology and design associated with US general aviation revitalization and aviation safety programs. The presented problem addressed NASA's strategic outcome to widely communicate the content, relevancy and excitement of its missions and discoveries to the general population. Further, the PBL scenario addressed the technological challenges being taken up by NASA to revolutionize air travel and the way in which aircraft are designed, built, and operated. It also addressed getting people and freight safely and efficiently to any location in the world at a reasonable cost. With a "real" need-to-know problem facing them, the teachers set out to gather information and to better understand the problem using inquiry-based and scientific methods. The learning in this aeronautics scenario was

    Full Text Available The main objective of problem-based learning (PBL is to provoke students to solve a new problem by themselves. The aim of this study was to investigate whether PBL was a better method of teaching basic and advanced life support to medical students compared with the classical method. The research was undertaken in 2002 in accordance with the European Guidelines 2000 and involved 36 medical students in year 4. The students were divided into two groups: experimental PBL group (17 students and the control-classical method group (19 students. After the advanced life support course, the students wrote two tests to assess their knowledge on how to open the airway and how to perform basic and advanced resuscitation. The questions contained true or false answers. The students' skills of basic and advanced methods of opening the airway and advanced resuscitation were checked by practical tests. The Mann-Whitney test was used for statistical analysis. The experimental PBL group received significantly better results: 30–45 points (mean, 38.29 points and 30–47 points (mean, 40.94 points for the written and practical tests, respectively, compared with the control-classical group (22–34 points [mean, 29.36 points] and 22–35 points [mean, 28.63 points], respectively. Therefore, PBL offers a better method for teaching basic and advanced life support to medical students compared with the classical method.

    Campus university building is the Higher Learning Institution (HLI) involves complex activities and operations, conserving the energy has become paramount important. There are several efforts taken by universities to improve its current energy use such as policy development, education, and adaption of energy conservation solution through retrofitting. This paper aims to highlight the importance of the criteria affecting in retrofitting of existing buildings with clean energy in order to achieve zero energy balance in buildings. The focus is given to the development of criteria for solar photovoltaic (solar PV), wind turbines and small-scale hydropower. A questionnaire survey was employed and distributed to the green building expert practitioner. Factor Analysis, Factor Score, and Weightage Factor were adapted as a method of analysis in order to produce the final result with weightage output for prioritization and ranking of the relevant criteria. The result performed assists to provide the stakeholders an overview of the important criteria that should be considered especially during the decision making to retrofit the existing buildings with clean energy resources. The criteria developed are also to establish a structured decision-making process and to ensure the selection of the decision or alternatives achieve the desired outcome.

    BackgroundImproved teamwork between conventional and complementary medicine (CM) practitioners is indicated to achieve effective healthcare. However, little is known about interprofessional collaboration and education in the context of integrative medicine (IM). MethodsThis paper reports the findings from a constructivist-grounded theory method study that explored and highlighted Australian medical students' experiences and opportunities for linking interprofessional collaboration and learning in the context of IM. Following ethical approval, in-depth semi-structured interviews were conducted with 30 medical students from 10 medical education faculties across Australian universities. Results Medical students recognised the importance of interprofessional teamwork between general medical practitioners and CM professionals in patient care and described perspectives of shared responsibilities, profession-specific responsibilities, and collaborative approaches within IM. While students identified that limited interprofessional collaboration currently occurred in the medical curriculum, interprofessional education was considered a means of increasing communication and collaboration between healthcare professionals, helping coordinate effective patient care, and understanding each healthcare team members' professional role and value. Conclusions The findings suggest that medical curricula should include opportunities for medical students to develop required skills, behaviours, and attitudes for interprofessional collaboration and interprofessional education within the context of IM. While this is a qualitative study that reflects theoretical saturation from a selected cohort of medical students, the results also point to the importance of including CM professionals within interprofessional collaboration, thus contributing to more person-centred care.

    Single-port total laparoscopic hysterectomy (TLH) has not been widely used because of its technical difficulty and steep learning curve, especially the laparoscopic suturing of the vaginal stump. Barbed suturing is a new technology that has the potential to greatly facilitate laparoscopic suturing. To compare surgical outcomes and vaginal vault healing between barbed sutures and traditional sutures in the repair of the vaginal vault during single-port TLH. Between August 2013 and June 2015, we performed single-port TLH in 85 consecutive patients for benign or premalignant gynecological conditions. The first 48 patients underwent single-port TLH with traditional interrupted sutures, and the next 37 patients underwent single-port TLH with absorbable unidirectional knotless barbed sutures for repair of the vaginal vault. The patient characteristics (age, body mass index), procedures performed, uterine weight, and uterine disease were similar between the groups. There were no differences in blood loss, hemoglobin change, length of hospital stay, or perioperative complications. Operative time and the time required for vaginal cuff suturing were significantly shorter in the barbed suture group than in the traditional suture group (57.8 ±13.5 vs. 80.1 ±18.7 min, p < 0.001; 5.5 ±1.7 vs. 12.9 ±3.5 min, p < 0.001). Moreover, the use of barbed sutures significantly reduced the incidence of vaginal granulation tissue formation (2.7% vs. 35.4%, p < 0.001). Use of barbed sutures in single-port TLH reduced the operative time, suturing time of the vaginal vault, and formation of vaginal granulation tissue. Barbed suturing may help overcome surgical difficulties and vaginal cuff complications.

    Full Text Available We look at how marginal education spaces are differently imagined and (reproduced. We trace aspects of learners’ journeys and the different pathways into Initial Teacher Training (ITT made available through a university and an Adult Education-based networking organisation in the Lifelong Learning Sector (LLS in England. We focus on urban localities and the venues used to offer and run PTLLS courses aimed at attracting Black and Minority Ethnic (BME recruits to teaching careers. We compare the profiles of these trainee groups and the effect of the different approaches taken by these organisations. We look at organisational and spatial aspects of training ‘offers’ and provision, the impacts of this on the recruitment of learners and how teaching careers are differently imagined within this marginal space. We conclude with suggestions for altering the discourse used to review and plan the recruitment of BME teacher trainees.

    Background Phadia/EliA fluorescence enzyme immunoassays are widely used automated assays for anticardiolipin (aCL) and anti-β2-glycoprotein I (aβ2GPI) antibodies. To date, cut-off values for these assays have not been evaluated systematically and the evidence behind manufacturer's recommended cut-off values is not clear. Objective To determine Phadia/EliA cut-off values for antiphospholipid antibodies (aPL) according to the procedures suggested by guidelines. Methods A total of 266 blood donors (135 females and 131 males) were included. The pre-handling and analysis of the samples were performed according to the International Society on Thrombosis and Hemostasis (ISTH) guideline for solid phase aPL assays. Cut-off values and corresponding 90% confidence intervals (CI) for each antibody were established and outliers were handled according to the Clinical and Laboratory Standards Institute (CLSI) guideline for reference intervals. Samples from 377 consecutive patients, referred to our thrombophilia center with evidence of thrombosis or pregnancy morbidity were included for aPL testing. Results The in-house 99th (97.5th) percentile cut-off values were 11 (8.7), 12 (6.9) 8.5 (5.0) AU/mL for aβ2GPI IgG, IgM and IgA, and 21 (13) GPL-U/mL and 41 (25) MPL-U/mL for aCL IgG and IgM, respectively. The prevalence of positive results (%) defined by these cut-off values in patients with evidence of thrombosis or pregnancy morbidity was 9.5 (12.2), 1.6 (2.9), and 7.0 (9.9), and 0.8 (3.8) for aβ2GPI IgG, IgM, and aCL IgG and IgM respectively. The use of in-house 99th percentile cut-off values compared to the manufacturer suggested cut-off values resulted in 1 and 39 fewer samples for aβ2GPI and aCL to be classified as positive for aPL, respectively. Conclusions We present Phadia/EliA cut-off values with 90% CI for aPL determined systematically according to the ISTH and CLSI guidelines. These values are different from values previously determined, suggesting variation of a

Our purpose is to describe the initial experience with intravenous pentobarbital sedation in children undergoing MRI at a tertiary pediatric hospital to identify errors associated with inexperience. Subjects and methods. The study included the first 100 children sedated with intravenous pentobarbital prior to magnetic resonance examination at a tertiary pediatric hospital. The protocol included a maximum dose of 6 mg/kg administered in three divided doses with the total dose not to exceed 200 mg. Flow sheets documenting vital signs, administered drug doses, and adverse reactions were maintained contemporaneous to sedation. Results. Sedation was successful in 92 children. Of the eight children who failed sedation, three were at least 12 years old and three weighed more than 50 kg. χ 2 tests identified significantly greater failure rates in children older than 11 years or weight greater than 50 kg. Two children had prolonged sedation after the maximum suggested dose was exceeded. Conclusions. The success rate was good, but could have been improved by restricting the use of pentobarbital to children less than 12 years of age and weighing less than 50 kg. Radiologists inexperienced with intravenous sedation should strictly observe the maximum suggested dose of pentobarbital to prevent prolonged sedation. (orig.)

  6. Differentiation, context and teacher education: the changing profile of trainees on in-service initial teacher training programmes in the lifelong learning sector

    2009-01-01

    Full Text Available Analysis of initial teacher training (ITT student data relating to the University of Huddersfield part-time in-service Cert Ed/PGCE over a three-year period has revealed significant change in the make-up of trainee cohorts. There has been an increase in younger trainees and in trainees very new to teaching, although more experienced and older trainees do continue to enrol. There has also been a considerable shift in the balance of trainees away from further education (FE college staff. These changes have implications for those who manage and deliver teacher education for the sector. It remains of key importance that the curriculum is not experienced as overly ‘FE-college centric’ and that mentoring arrangements acknowledge the needs of trainees from diverse contexts. It is clear that in the delivery of ITT for the lifelong learning sector, increasingly, one size will not comfortably fit all. Within teacher education much emphasis is placed upon the role of differentiation in regard to trainee practice. The changing trainee profile identified requires that teacher education itself unambiguously models a differentiated approach – and, in relation to teacher education for the lifelong learning sector, differentiation must address workplace context.

    We report the development of a new "Case of the Day" (COTD) educational initiative using email, social media (SoMe), and a website to disseminate content, as well as its trends in viewership and assessment of utility for the first year of implementation. Using an image-rich format, a new unknown case was disseminated to radiology trainees and attendings at our institution by email twice per week, including history, salient images, and follow-up questions. Simultaneously, content was externally disseminated on Twitter and a publicly viewable departmental website. On subsequent days, the answer was posted via email, Twitter, and website in the form of a brief YouTube video lecture. Viewership data were collected over the first 12 months (July 1, 2016 to June 30, 2017), and an anonymous survey of participants was performed. Sixty-five COTDs had complete viewership data and were included in our analysis, yielding 4911 "case" email views (mean = 76), 3798 "answer" email views (mean = 58), 68,034 "case" Twitter impressions (mean = 1047), 75,724 "answer" Twitter impressions (mean = 1164), 5465 "case" Twitter engagements (mean = 84), and 5307 "answer" Twitter engagements (mean = 82). COTD YouTube video lectures garnered 3657 views (mean = 61) amounting to 10,358 minutes of total viewing time. Viewers were very satisfied with COTD quality, with 97% (n = 63) reporting the quality as "good" or "excellent." Email and SoMe can serve as effective tools for disseminating radiology educational content. SoMe offers substantial external visibility and branding potential for programs.

    The authors describe 3 large randomized trials from the Cancer Information Service Research Consortium. Three web-based multimedia programs are being tested to help newly diagnosed prostate (Project 1) and breast cancer patients (Project 2) make informed treatment decisions and breast cancer patients prepare for life after treatment (Project 3). Project 3 also tests a telephone callback intervention delivered by a cancer information specialist. All participants receive standard print material specific to each project. Preliminary results from the 2-month follow-up interviews are reported for the initial wave of enrolled participants, most of whom were recruited from the Cancer Information Service (1-800-4-CANCER) telephone information program (Project 1: n =208; Project 2: n =340; Project 3: n =792). Self-reported use of the multimedia program was 51%, 52%, and 67% for Projects 1, 2, and 3, respectively. Self-reported use of the print materials (read all, most, or some) was 90%, 85%, and 83% for Projects 1, 2, and 3, respectively. The callback intervention was completed by 92% of Project 3 participants. Among those using the Cancer Information Service Research Consortium interventions, perceived usefulness and benefit was high, and more than 90% reported that they would recommend them to other cancer patients. The authors present 5 initial lessons learned that may help inform future cancer communications research.

    Health promotion has made significant strides in the past few decades in the Americas. Creating a healthy and supportive setting, also known as the settings approach, continues to be one of the most widely used health promotion strategies. Interest in evaluating the effectiveness of these strategies has been increasing greatly in the past few years. Participatory evaluation holds great promise for helping to generate this evidence and promote understanding of the factors that affect, positively or negatively, the advances of health promotion in the Region. During 2004-2006, a Participatory Evaluation methodology was introduced into several countries in the Americas through formal trainings conducted by the Pan American Health Organization (PAHO) in collaboration with country partners. This article summarizes the main lessons learned from the application of the participatory evaluation methodology in various countries in Latin America and the Caribbean. Factors affecting the evaluation of the initiatives were identified at multiple levels (individual, community, organizational, political, economic, etc.). Specific issues that were addressed included the political context, turnover of personnel in key institutions, concerns related to the effectiveness of participatory processes, and the existence of strong and sustained leadership at the country level. These factors are intertwined and affect each other in very complex ways, a fact that was reflected in the municipalities' experiences with participatory evaluation. Challenges included the ability to secure resources for the evaluation, the time needed to conclude the process, and working in an intersectoral manner. However, participating municipalities reported that the process of implementing a participatory evaluation and working with various stakeholders had an empowering effect: communities and stakeholders were more willing and interested in participating in health promotion initiatives in a sustained manner

    2009-01-01

    Full Text Available Este texto realiza el retrato del líder político más importante de la primera parte del siglo XX en Colombia, el liberal Jorge Eliécer Gaitán, asesinado el 9 de abril de 1948, cuando la Presidencia de la República parecía estar a su alcance. Desde entonces, su fantasma acosó a una Colombia donde la violencia estalló y se mantuvo durante toda la segunda parte del siglo XX, con breves interrupciones. En este contexto, su trayectoria y pensamiento no dejaron de ser objetos de controversias y debates apasionados. El esfuerzo de clarifi cación conduce a reconocer la filiación populista del político colombiano. Es así como, a pesar de la ausencia de una experiencia populista duradera, el populismo tuvo un impacto central en la historia contemporánea del país andino. Las consecuencias de la presencia de esa ausencia son materia a reflexión sobre el resurgir de los populismos y el estancamiento democrático en la América latina contemporánea.

  16. Effects of correlations between particle longitudinal positions and transverse plane on bunch length measurement: a case study on GBS electron LINAC at ELI-NP

    In high-brightness LINear ACcelerators (LINACs), electron bunch length can be measured indirectly by a radio frequency deflector (RFD). In this paper, the accuracy loss arising from non-negligible correlations between particle longitudinal positions and the transverse plane (in particular the vertical one) at RFD entrance is analytically assessed. Theoretical predictions are compared with simulation results, obtained by means of ELEctron Generation ANd Tracking (ELEGANT) code, in the case study of the gamma beam system (GBS) at the extreme light infrastructure—nuclear physics (ELI-NP). In particular, the relative error affecting the bunch length measurement, for bunches characterized by both energy chirp and fixed correlation coefficients between longitudinal particle positions and the vertical plane, is reported. Moreover, the relative error versus the correlation coefficients is shown for fixed RFD phase 0 rad and π rad. The relationship between relative error and correlations factors can help the decision of using the bunch length measurement technique with one or two vertical spot size measurements in order to cancel the correlations contribution. In the case of the GBS electron LINAC, the misalignment of one of the quadrupoles before the RFD between  -2 mm and 2 mm leads to a relative error less than 5%. The misalignment of the first C-band accelerating section between  -2 mm and 2 mm could lead to a relative error up to 10%.

    The performance of Chemical Vapor Deposition (CVD) carbide insert with ISO designation of CCMT 12 04 04 LF, when turning titanium alloys was investigated. There were four layers of coating materials for this insert i.e.TiN-Al2O3-TiCN-TiN. The insert performance was evaluated based on the insert's edge resistant towards the machining parameters used at high cutting speed range of machining Ti-6Al-4V ELI. Detailed study on the wear mechanism at the cutting edge of CVD carbide tools was carried out at cutting speed of 55-95 m/min, feed rate of 0.15-0.35 mm/rev and depth of cut of 0.10-0.20 mm. Wear mechanisms such as abrasive and adhesive were observed on the flank face. Crater wear due to diffusion was also observed on the rake race. The abrasive wear occurred more at nose radius and the fracture on tool were found at the feed rate of 0.35 mm/rev and the depth of cut of 0.20 mm. The adhesion wear takes place after the removal of the coating or coating delaminating. Therefore, adhesion or welding of titanium alloy onto the flank and rake faces demonstrates a strong bond at the workpiece-tool interface.

    Full Text Available Objective: To determine the sensitivity and specificity of five available scales to the qualification of the Tonal Audiometry for the detection of occupationally induced hearing loss. Methods: A descriptive cross-sectional study was conducted. The study population was 92 adult workers. Participants underwent the application of the different formats of registration of the results and qualification of the tonal audiometry. Participants received a hearing evaluation by clinical audiometry. Sixty four cases met the inclusion criteria and were selected for the final analysis.Once the tonal audiometry was complete, evaluation of occupationally induced hearing loss was done by using the ELI, salt, modified LARSEN, KLOCKHOFF and NIOSH classification scales. Results were compared to FREQUENCIAL analysis. Results: The LARSEN scale was noted to detect more cases of occupationally induced hearing loss. The LARSEN modified, represented detection in 54.69% of cases for right ear and 56.25% of cases for left ear. On the other hand, noted the direct relationship of hearing loss with regard to the age. No direct correlation to time of noise exposure was found.. Conclusions: The rating scale that presented greater sensitivity was the LARSEN modified. It was represented by 93.1% and a specificity of 100%.

    Community-based coastal resource management has been widely applied within the Philippines. However, small-scale community-based reserves are often inefficient owing to management inadequacies arising because of a lack of local support or enforcement or poor design. Because there are many potential pitfalls during the establishment of even small community-based reserves, it is important for coastal managers, communities, and facilitating institutions to have access to a summary of the key factors for success. Reviewing relevant literature, we present a framework of "lessons learned" during the establishment of protected areas, mainly in the Philippines. The framework contains summary guidance on the importance of (1) an island location, (2) small community population size, (3) minimal effect of land-based development, (4) application of a bottom-up approach, (5) an external facilitating institution, (6) acquisition of title, (7) use of a scientific information database, (8) stakeholder involvement, (9) the establishment of legislation, (10) community empowerment, (11) alternative livelihood schemes, (12) surveillance, (13) tangible management results, (14) continued involvement of external groups after reserve establishment, and (15) small-scale project expansion.These framework components guided the establishment of a community-based protected area at Danjugan Island, Negros Occidental, Philippines. This case study showed that the framework was a useful guide that led to establishing and implementing a community-based marine reserve. Evaluation of the reserve using standard criteria developed for the Philippines shows that the Danjugan Island protected area can be considered successful and sustainable. At Danjugan Island, all of the lessons synthesized in the framework were important and should be considered elsewhere, even for relatively small projects. As shown in previous projects in the Philippines, local involvement and stewardship of the protected area

    2017-06-01

    Full Text Available Mexico, like many low- and middle-income countries (LMICs, faces an epidemic of chronic non-communicable diseases (NCDs, specifically diabetes, hypertension, obesity, and lipid disorders. Many people with these NCDs may not be aware that they have a disease, pointing to the need for broader screening programs. The traditional prevention policy in Mexico was based on screening with a paper-based risk factor questionnaire. However, this was used to screen patients already seeking healthcare services at facilities, and screening goals were set as a function of the number of questionnaires applied, not number of individuals screened. Due to this, Fundación Carlos Slim developed Medición Integrada para la Detección Oportuna (MIDOTM, or Integrated Measurement for Early Detection, an NCD screening and proactive prevention policy. This document is a policy analysis based on early learnings from the initial implementation of MIDO in eight primary healthcare centers in two central Mexican states. MIDO was found to expand screening programs beyond clinic walls, systematize community screening strategies, emphasize the detection of pre-disease phases, incorporate lifestyle counseling, and propose screening goals based on population targets. In collaboration with the Mexican Ministry of Health, MIDO has successfully screened over 500 000 individuals—about 40% of whom would not have been screened under previous policies. Of these more than 500 000 screened individuals, 13.4% had pre-diabetes (fasting glucose between 100 and 125 mg/dL, and 5.8% had undiagnosed diabetes (defined as fasting glucose above 126 mg/dL or random glucose above 200 mg/dL. However, there is still room for improvement in linking positive results from screening with disease confirmation and with patient incorporation into disease management. The experience of implementing MIDO in Mexico suggests that primary and secondary prevention programs in other parts of the world should

    Full Text Available ELI-NP will be a new international research infrastructure facility for laser-based Nuclear Physics to be built in Magurele, south west of Bucharest, Romania. For the machine to operate as an intense γ rays’ source based on Compton back-scattering, electron beams are employed, undergoing a two stage acceleration to 320 MeV and 740 MeV (and, with an eventual energy upgrade, also to 840 MeV beam energies. In order to assess the radiation safety issues, concerning the effectiveness of the dumps in absorbing the primary electron beams, the generated prompt radiation field and the residual dose rates coming from the activation of constituent materials, as well as the shielding of the adjacent environments against both prompt and residual radiation fields, an extensive design study by means of Monte Carlo simulations with FLUKA code was performed, for both low energy 320 MeV and high energy 720 MeV (840 MeV beam dumps. For the low energy dump we discuss also the rational of the choice to place it in the building basement, instead of installing it in one of the shielding wall at the machine level, as it was originally conceived. Ambient dose equivalent rate constraints, according to the Rumenian law in force in radiation protection matter were 0.1 /iSv/h everywhere outside the shielding walls and 1.4 μiSv/h outside the high energy dump area. The dumps’ placements and layouts are shown to be fully compliant with the dose constraints and environmental impact.

    Full Text Available Within the scope of corporate waste management, Sisak Steelworks initiated a thorough and systematic examination of physical and chemical properties of metallurgical waste and of its behaviour in interaction with the environment. Electric arc furnace (EAF dust has been categorized as hazardous technological waste and it can not be directly disposed of to the ground / in a land fill. Therefore, it is necessary to find a way to dispose of it in an environmentally friendly and economically acceptable manner. In order to elaborate different options and chose the optimal practice for the disposal of the accumulated volumes of hazardous metallurgical waste, comprehensive and systematic research has been conducted. This paper provides only a partial survey of the research of the heavy metal Zn, Pb, Cd content in electric arc furnace dust as well. Qualitative chemical analysis of samples of electric arc furnace dust was conducted on all observed samples and the presence of Fe, Zn, Pb, Mn, Cu, Al, Ca, Mg, K, S, P, C, O and Cl was established. The results of qualitative chemical analysis of monthly average samples of electric arc furnace dust obtained by other methods established that the mass fraction of iron was between 41.08 and 48.58 %, zinc between 3.75 and 8.10 %, lead between 0.94 and 2.07 %, and cadmium between 0.010 and 0.027 %. The results of the Zn, Pb, Cd fraction analysis in the observed samples of electric arc furnace dust are considerably lower, than the content of those metals in EAF dusts presented in the available references, where the mass fraction of zinc varies between 0.14 and 50 %, lead between 0.03 and 6.8 %, and cadmium between < 0.01 and 1.8 %. Quantitative analysis of Fe, Zn, Pb and Cd fraction was carried out in grain-metrical fractions of individual samples of EAF dust as well. The results have shown that the concentrations of Fe tend to increase with smaller fraction grains compared to an average sample, whereas

    Narcolepsy type 1, a neurological sleep disorder strongly associated with Human Leukocyte Antigen (HLA-)DQB1*06:02, is caused by the loss of hypothalamic neurons producing the wake-promoting neuropeptide hypocretin (hcrt, also known as orexin). This loss is believed to be caused by an autoimmune...... reaction. To test whether hcrt itself could be a possible target in the autoimmune attack, CD4(+) T-cell reactivity towards six different 15-mer peptides from prepro-hypocretin with high predicted affinity to the DQA1*01:02/DQB1*06:02 MHC class II dimer was tested using EliSpot in a cohort of 22 narcolepsy...

  15. Conflicting demands in prison education and the need for context-specific, specialist training for prison educators: an account of the work of the Initial Teacher Training project for teachers and instructors in London prisons and offender learning

    2009-01-01

    Full Text Available Prison Education is regulated by legislative and institutional requirements as are other kinds of Learning and Skill provision, but it is also fundamentally affected by the custodial requirements of the British Legal system. This, together with the relative isolation that teaching staff face within an organisational culture which is peculiar to each prison, produces a learning culture that is very different from that of general Further Education. This paper discusses initial findings of the LONCETT Prison Education Research Project (2008, which aims to identify the specific professional training needs of prison educators in London. Findings from five of the eight prisons in London highlighted two main pedagogic issues that emerged as key aspects of prison education practice which require both specialist training input and further research: the fragmentation which characterises the learner experience; and the emotional stress produced in this environment, which impacts both upon prisoner-learners and teaching staff.

  16. Unilateral initiatives

    This paper reports on arms control which is generally thought of in terms of formal negotiations with an opponent, with the resulting agreements embodied in a treaty. This is not surprising, since arms control discussions between opponents are both important and politically visible. There are, however, strong reasons for countries to consider and frequently take unilateral initiatives. To do so is entirely consistent with the established major precepts of arms control which state that arms control is designed to reduce the risk of war, the costs of preparing for war, and the death and destruction if war should come. Unilateral initiatives on what weapons are purchased, which ones are eliminated and how forces are deployed can all relate to these objectives. There are two main categories of motives for unilateral initiatives in arms control. In one category, internal national objectives are the dominant, often sole, driving force; the initiative is undertaken for our own good

    Full Text Available We present a study of psychological characteristics of preadult orphans, their psychological adaptation to the conditions of learning in high school compared to the norm population (students living in family. We assumed that the level of adaptation of the orphan students is significantly smaller than in other students, because of their special life circumstances (maternal deprivation, living in residential care institutions, sometimes bad heredity, lack of life skills in everyday issues, personal problems. The results of the survey of 49 orphan students (26 girls and 23 boys and 49 first-year students brought up by parents (28 girls and 21 boys, confirmed this hypothesis and allow us to tell that orphan students need special psychological help in the learning process in high school to grow at a personal and professional level.

    Initiatives that convene community stakeholders to implement policy, systems, environment, and infrastructure (PSEI) change have become a standard approach for promoting community health. To assess the PSEI changes brought about by the King County, Washington, Communities Putting Prevention to Work initiative and describe how initiative structures and processes contributed to making changes. The impact evaluation used a logic model design, linking PSEI changes to longer-term behavioral impacts in healthy eating active living and tobacco use and exposure. Qualitative methods, including stakeholder interviews and surveys, were used to identify initiative success factors. Communities Putting Prevention to Work activities occurred throughout King County, with a focus on 7 low-income communities in South Seattle/King County. The focus communities had a combined population of 652 000, or 35% of the county total, with lower incomes and higher rates of physical inactivity, tobacco use, poor diet, and chronic disease. Twenty-four PSEI strategies were pursued by organizations in sectors including schools, local governments, and community organizations, supported by the public health department. There were 17 healthy eating active living strategies (eg, enhancements to school menus, city planning policies) and 7 tobacco strategies (eg, smoke-free policies in schools, housing, and hospitals). PSEI changes made and numbers of residents reached. Twenty-two of the 24 strategies achieved significant progress toward implementing PSEI changes. The most common success factor was a "dyad" consisting of a dedicated technical assistance provider-either an outside consultant or public health department staff-working closely with a champion from the participating organizations to bring about PSEI changes. An initiative structure that creates and supports external consultant/internal organizational champion dyads in key community sectors offers a promising approach that may be adopted by

    Full Text Available The primary motor cortex (M1 contributes to the acquisition and early consolidation of a motor sequence. Although the relevance of M1 excitability for motor learning has been supported, the significance of M1 oscillations remains an open issue. This study aims at investigating to what extent retrieval of a newly learned motor sequence can be differentially affected by motor-cortical transcranial alternating (tACS and direct current stimulation (tDCS. Alpha (10 Hz, beta (20 Hz or sham tACS was applied in 36 right-handers. Anodal or cathodal tDCS was applied in 30 right-handers. Participants learned an eight-digit serial reaction time task (SRTT; sequential vs. random with the right hand. Stimulation was applied to the left M1 after SRTT acquisition at rest for ten minutes. Reaction times were analyzed at baseline, end of acquisition, retrieval immediately after stimulation and reacquisition after eight further sequence repetitions.Reaction times during retrieval were significantly faster following 20 Hz tACS as compared to 10 Hz and sham tACS indicating a facilitation of early consolidation. TDCS yielded faster reaction times, too, independent of polarity. No significant differences between 20 Hz tACS and tDCS effects on retrieval were found suggesting that 20 Hz effects might be associated with altered motor-cortical excitability. Based on the behavioural modulation yielded by tACS and tDCS one might speculate that altered motor-cortical beta oscillations support early motor consolidation possibly associated with neuroplastic reorganization.

    "Flipped classroom" teaching methodology is a type of blended learning in which the traditional class setting is inverted. Lecture is shifted outside of class, while the classroom time is employed to solve problems or doing practical works through the discussion/peer collaboration of students and instructors. This relatively new instructional methodology claims that flipping your classroom engages more effectively students with the learning process, achieving better teaching results. Thus, this research aimed to evaluate the effects of the flipped classroom on the students' performance and perception of this new methodology. This study was conducted in a general science course, sophomore of the Primary Education bachelor degree in the Training Teaching School of the University of Extremadura (Spain) during the course 2014/2015. In order to assess the suitability of the proposed methodology, the class was divided in two groups. For the first group, a traditional methodology was followed, and it was used as control. On the other hand, the "flipped classroom" methodology was used in the second group, where the students were given diverse materials, such as video lessons and reading materials, before the class to be revised at home by them. Online questionnaires were as well provided to assess the progress of the students before the class. Finally, the results were compared in terms of students' achievements and a post-task survey was also conducted to know the students' perceptions. A statistically significant difference was found on all assessments with the flipped class students performing higher on average. In addition, most students had a favorable perception about the flipped classroom noting the ability to pause, rewind and review lectures, as well as increased individualized learning and increased teacher availability.

    In order to establish a new personalized breast cancer screening paradigm, it is critically important to accurately predict the short-term risk of a woman having image-detectable cancer after a negative mammographic screening. In this study, we developed and tested a novel short-term risk assessment model based on deep learning method. During the experiment, a number of 270 "prior" negative screening cases was assembled. In the next sequential ("current") screening mammography, 135 cases were positive and 135 cases remained negative. These cases were randomly divided into a training set with 200 cases and a testing set with 70 cases. A deep learning based computer-aided diagnosis (CAD) scheme was then developed for the risk assessment, which consists of two modules: adaptive feature identification module and risk prediction module. The adaptive feature identification module is composed of three pairs of convolution-max-pooling layers, which contains 20, 10, and 5 feature maps respectively. The risk prediction module is implemented by a multiple layer perception (MLP) classifier, which produces a risk score to predict the likelihood of the woman developing short-term mammography-detectable cancer. The result shows that the new CAD-based risk model yielded a positive predictive value of 69.2% and a negative predictive value of 74.2%, with a total prediction accuracy of 71.4%. This study demonstrated that applying a new deep learning technology may have significant potential to develop a new short-term risk predicting scheme with improved performance in detecting early abnormal symptom from the negative mammograms.

    2014-01-01

    Lessons Learned: Although the HTR-PM and FSV incorporate significant differences in their designs, there are lessons to be learned that are applicable to both plants. This is especially important for key systems that incorporate first-of-a-kind equipment. Basically, these lessons are just an application of common sense. • Complexity Breeds Unavailability. Incorporate system/components that are ruggedly simple in design with a history of reliable operation and minimal maintenance. • Assure Strong Expertise and Funding for this First HTR-PM. Quite likely, the successful startup and operation of this plant will require a level of support considerably greater than a typical nuclear plant. • Be Very Attentive to the Design Aspects of first-of-a-kind Components in the Class 1, Safety-Related Portions of the Plant. For example; a generic metallurgical failure could easily lead to a very long plant shutdown in order to redesign the failed component, re-license, manufacture, install and test prior to plant resuming plant operation. • Where Possible, Test all Key Systems/Components Prior to Installation using Actual Plant Configuration & Operating Characteristics This will help assure operational capability prior to application of nuclear heat. • Never Attempt to Start an Innovative Nuclear Power Plant Without First Having the Proper Regulatory Guides and Criteria in Place. FSV was licensed as a Research Facility. There was no Standard Review Plan or Regulatory Guides in place for the NRC (or PSC) to utilize in regulating this HTGR. • Do Not Be Reluctant to Incorporate a Generous Over-Build Capability into Systems/Components. It is significantly easier to design extra margin into the original compressors, pumps and motors than to be required to backfit into larger units after plant start-up. • Assure All Safety Documents Reflect the Actual Capability of the Plant to Respond to Accidents Described in the Safety Analysis. FSV was limited to 82% power during the

    Preclinical and early clinical external pelvic stabilization using commercially available devices has become common in trauma patient care. Thus, in the emergency department an increasing number of patients will undergo radiographic evaluation of the externally stabilized pelvis to exclude injuries. While reports exist where injuries to the pelvis were elusive to radiological examination due to the pelvic immobilization we elaborate on an algorithm to remove an external pelvic stabilizing device, prevent delayed diagnosis of pelvic disruption and thus increase patient safety. We report on two patients with external pelvic stabilization presenting with an inconspicuous pubic symphysis on initial pelvic computed tomography scans. The first patient was an otherwise healthy 51-year old male being run over by his own car. He received external pelvic stabilization in the emergency department. The second patient was a 36-year old male falling from a ladder. In this patient external pelvic stabilization was performed at the scene. In the first patient no pelvic injury was obvious on computed tomography. In the second patient pelvic fractures were diagnosed, yet the presentation of the pubic symphysis appeared normal. Nevertheless, complete symphyseal disruption was diagnosed in both of them upon removal of the external pelvic stabilization and consequently required internal fixation. Based on our experience we propose an algorithm to "clear the initially immobilized pelvis" in an effort to minimize the risk of missing a serious pelvic injury and increase patient safety. This is of significant importance to orthopedic trauma surgeons and emergency physicians taking care of injured patients.

    The lifting in 2010 of the HIV entry ban eliminated an access point for HIV testing of the foreign-born. The African Diaspora Health Initiative (ADHI) was developed to examine alternative pathways to testing for African and Caribbean persons. The ADHI consists of Clinics Without Walls (CWW) held in community settings. HIV testing is offered to participants along with hypertension and diabetes screening. A survey is administered to participants. Descriptive data were analyzed using SAS 9.2. Between 2011 and 2015, 4152 African and Caribbean individuals participated in 352 CWW. Participants were mostly (67.7 %) African. HIV rates were lowest in Caribbean women (0.4 %) and highest in Caribbean men (8.4 %). Efforts to engage African and Caribbean communities in HIV testing are important given the elimination of the HIV entry ban and continued immigration to the US from areas of higher prevalence. The ADHI offers a successful model of engagement.

    House staff quality improvement projects are often not aligned with training institution priorities. House staff are the primary users of inpatient problem lists in academic medical centers, and list maintenance has significant patient safety and financial implications. Improvement of the problem list is an important objective for hospitals with electronic health records under the Meaningful Use program. House staff surveys were used to create an electronic problem list manager (PLM) tool enabling efficient problem list updating. Number of new problems added and house staff perceptions of the problem list were compared before and after PLM intervention. The PLM was used by 654 house staff after release. Surveys demonstrated increased problem list updating (P = .002; response rate 47%). Mean new problems added per day increased from 64 pre-PLM to 125 post-PLM (P house staff in institutional quality and safety initiatives with tangible institutional benefits.

    2018-01-01

    The purposes of this study were to (a) explore whether early fractions understanding at 4 th grade is differentially challenging for students with versus without adequate whole-number competence and (b) identify specific whole-number skill associated with difficulty in fractions understanding. Based on initial whole-number competence, 1,108 4 th graders were classified as having (a) adequate whole-number competence ( n = 775), (b) less severe whole-number difficulty ( n = 201), and (c) severe whole-number difficulty ( n = 132). At the end of 4 th grade, they were assessed on fractions understanding and further classified as with versus without difficulty in fractions understanding. Multi-level logistic regression indicated that compared to students with adequate whole-number competence, those with less severe whole-number difficulty were almost 5 times as likely to experience difficulty with fractions understanding whereas those with severe whole-number difficulty were about 32 times as likely to experience difficulty with fractions understanding. Students with severe whole-number difficulty were about 7 times as likely to experience difficulty with fractions understanding compared to those with less severe whole-number difficulty. Among students with adequate whole-number competence, the pretest whole-number skill distinguishing those with versus without difficulty in fractions understanding was basic division facts (i.e., 2-digit dividend ÷ 1-digit divisor) and simple multiplication (i.e., 3-digit × 1-digit without regrouping). The role of whole-number competence in developing initial fractions understanding and implications for instruction are discussed.

    The development of novel compact PET radionuclide production systems is of great interest to promote the diffusion of PET diagnostics, especially in view of the continuous development of microfluidics labeling approaches. We studied the feasibility to produce clinically-relevant amounts of PET isotopes by means of laser-accelerated proton sources such that expected at the ELI-Beamlines facility. "1"8F, "1"1C, "1"3N and "1"5O production yields were calculated through the TALYS software, by taking into account the broad proton spectra expected. With the hypothesized proton fluencies, clinically-relevant amounts of radionuclides can be obtained, suitable to prepare single doses of "1"8F-, "1"1C- and "1"3N-labeled radiopharmaceuticals exploiting fast and efficient microfluidic labeling systems.

We evaluated the theoretical yields of 64Cu, 86Y, 89Zr, 73Se, 77Br and 124I PET isotopes, plus the 68Ge isotope, parent of the 68Ga positron emitter, in the hypothesis of production through laser-accelerated proton sources expected at the ELI-Beamlines facility. By means of the TALYS software we simulated the nuclear reactions leading to the above radionuclides, hypothesizing three possible scenarios of broad proton spectra, with maximum energies of about 9, 40 and 100 MeV. The production yields of the studied radionuclides, within the expected fluences, appear to be suitable for pre-clinical applications.

    The development of novel compact PET radionuclide production systems is of great interest to promote the diffusion of PET diagnostics, especially in view of the continuous development of microfluidics labeling approaches. We studied the feasibility to produce clinically-relevant amounts of PET isotopes by means of laser-accelerated proton sources such that expected at the ELI-Beamlines facility. {sup 18}F, {sup 11}C, {sup 13}N and {sup 15}O production yields were calculated through the TALYS software, by taking into account the broad proton spectra expected. With the hypothesized proton fluencies, clinically-relevant amounts of radionuclides can be obtained, suitable to prepare single doses of {sup 18}F-, {sup 11}C- and {sup 13}N-labeled radiopharmaceuticals exploiting fast and efficient microfluidic labeling systems.

    We consider research and theory relevant to the notion of informal learning. Beginning with historical and definitional issues, we argue that learning happens not just in schools or in school-aged children. Many theorists have contrasted informal learning with formal learning. Moving beyond this dichotomy, and away from a focus on where learning occurs, we discuss five dimensions of informal learning that are drawn from the literature: (1) non-didactive, (2) highly socially collaborative, (3) embedded in meaningful activity, (4) initiated by learner's interest or choice, and (5) removed from external assessment. We consider these dimensions in the context of four sample domains: learning a first language, learning about the mind and emotions within families and communities, learning about science in family conversations and museum settings, and workplace learning. Finally, we conclude by considering convergences and divergences across the different literatures and suggesting areas for future research.

    Full Text Available The didactic quality of lear0ning materialscan be improved by enriching learning material with didacticinformation. Such content elements assist selfdirectedlearning processes in virtual learningenvironments effectively. In order to develop didacticallymotivated for flexible use, e.g., at different terminaldevices such as PC or PDA, a structured procedure isrequired. We propose the selection and identification ofdidactically relevant information prior to enrichment ofhighly structured content with didactical information. Itcan be achieved by using the CoDEx method (ContentDidactically Explicit, and a mapping scheme to thelearning-technology standard conform XML contentstructures. Furthermore, aspects for multi-channel contentdelivery in the application field of engineering have to betaken into account. In this paper we refer to the objectivesand results of the EU-funded ELIE project (E-Learning InEngineering to demonstrate the proposed procedure’seffectiveness for content engineering.

    The Combat Wound Initiative (CWI) program is a collaborative, multidisciplinary, and interservice public-private partnership that provides personalized, state-of-the-art, and complex wound care via targeted clinical and translational research. The CWI uses a bench-to-bedside approach to translational research, including the rapid development of a human extracorporeal shock wave therapy (ESWT) study in complex wounds after establishing the potential efficacy, biologic mechanisms, and safety of this treatment modality in a murine model. Additional clinical trials include the prospective use of clinical data, serum and wound biomarkers, and wound gene expression profiles to predict wound healing/failure and additional clinical patient outcomes following combat-related trauma. These clinical research data are analyzed using machine-based learning algorithms to develop predictive treatment models to guide clinical decision-making. Future CWI directions include additional clinical trials and study centers and the refinement and deployment of our genetically driven, personalized medicine initiative to provide patient-specific care across multiple medical disciplines, with an emphasis on combat casualty care.

    Science.gov (United States)

    Yin, Haibo; Yang, Yun-an

    2017-05-01

    In this paper, we propose a new transfer learning algorithm for online training. The proposed algorithm, which is called Online Transfer Extreme Learning Machine (OTELM), is based on Online Sequential Extreme Learning Machine (OSELM) while it introduces Semi-Supervised Extreme Learning Machine (SSELM) to transfer knowledge from the source to the target domain. With the manifold regularization, SSELM picks out instances from the source domain that are less relevant to those in the target domain to initialize the online training, so as to improve the classification performance. Experimental results demonstrate that the proposed OTELM can effectively use instances in the source domain to enhance the learning performance.

    Narcolepsy type 1, a neurological sleep disorder strongly associated with Human Leukocyte Antigen (HLA-)DQB1*06:02, is caused by the loss of hypothalamic neurons producing the wake-promoting neuropeptide hypocretin (hcrt, also known as orexin). This loss is believed to be caused by an autoimmune reaction. To test whether hcrt itself could be a possible target in the autoimmune attack, CD4 + T-cell reactivity towards six different 15-mer peptides from prepro-hypocretin with high predicted affinity to the DQA1*01:02/DQB1*06:02 MHC class II dimer was tested using EliSpot in a cohort of 22 narcolepsy patients with low CSF hcrt levels, and 23 DQB1*06:02 positive healthy controls. Our ELISpot assay had a detection limit of 1:10,000 cells. We present data showing that autoreactive CD4 + T-cells targeting epitopes from the hcrt precursor in the context of MHC-DQA1*01:02/DQB1*06:02 are either not present or present in a frequency is <1:10,000 among peripheral CD4 + T-cells from narcolepsy type 1 patients.

    In view of the current poor learning initiative of undergraduates, the idea of creating a good learning environment and motivating active learning enthusiasm is proposed. In practice, the professional tutor is allocated and professional introduction course is opened for college freshman. It can promote communication between the professional teachers and students as early as possible, and guide students to know and devote the professional knowledge by the preconceived form. Practice results show that these solutions can improve the students interest in learning initiative, so that the active learning and self-learning has become a habit in the classroom.

    National energy policy supports the gathering of more detailed and authoritative data on the introduction of renewable bio-based fuels into new and existing district energy systems via the application of biomass gasification. The University of Iowa developed a biomass-fueled, university-scale steam generation system based on biomass gasification technologies. The system serves as a state-of-the-art research and educational facility in the emerging application of gasification in steam generation. The facility, which includes a smaller down-draft gasifier and a larger multi-stage biomass boiler, was designed to operate primarily on wood-based fuels, but has provisions for testing other biomass fuel sources produced within a 100-mile radius, providing enough flexibility to meet the fluctuating local supply of biomass from industry and Midwest agriculture. The equipment was installed in an existing, staffed facility. The down-draft gasifier unit is operated by College of Engineering staff and students, under the direct technical supervision of qualified Utilities plant staff. The Green Power Initiative also includes a substantial, innovative educational component. In addition to an onsite, graduate-level research program in biomass fuels, the investigators have integrated undergraduate and graduate level teaching – through classroom studies and experiential learning – and applied research into a biomass-based, university-scale, functioning power plant. University of Iowa is unique in that it currently has multiple renewable energy technologies deployed, including significant biomass combustion (oat hulls) at its Main Power Plant and a new reciprocating engine based renewable district energy system. This project complements and supports the national energy policy and State of Iowa initiatives in ethanol and biodiesel.

    2016-01-01

    SUMMARY The relationship between the brain and the environment is flexible, forming the foundation for our ability to learn. Here we review the current state of our understanding of the modifications in the sensorimotor pathway related to sensorimotor learning. We divide the process in three hierarchical levels with distinct goals: 1) sensory perceptual learning, 2) sensorimotor associative learning, and 3) motor skill learning. Perceptual learning optimizes the representations of important sensory stimuli. Associative learning and the initial phase of motor skill learning are ensured by feedback-based mechanisms that permit trial-and-error learning. The later phase of motor skill learning may primarily involve feedback-independent mechanisms operating under the classic Hebbian rule. With these changes under distinct constraints and mechanisms, sensorimotor learning establishes dedicated circuitry for the reproduction of stereotyped neural activity patterns and behavior.

  20. Does the cerebellum initiate movement?

    Thach, W T

    2014-02-01

    Opinion is divided on what the exact function of the cerebellum is. Experiments are summarized that support the following views: (1) the cerebellum is a combiner of multiple movement factors; (2) it contains anatomically fixed permanent focal representation of individual body parts (muscles and segments) and movement modes (e.g., vestibular driven vs. cognitive driven); (3) it contains flexible changing representations/memory of physical properties of the body parts including muscle strength, segment inertia, joint viscosity, and segmental interaction torques (dynamics); (4) it contains mechanisms for learning and storage of the properties in item no. 3 through trial-and-error practice; (5) it provides for linkage of body parts, motor modes, and motordynamics via the parallel fiber system; (6) it combines and integrates the many factors so as to initiate coordinated movements of the many body parts; (7) it is thus enabled to play the unique role of initiating coordinated movements; and (8) this unique causative role is evidenced by the fact that: (a) electrical stimulation of the cerebellum can initiate compound coordinated movements; (b) in naturally initiated compound movements, cerebellar discharge precedes that in downstream target structures such as motor cerebral cortex; and (c) cerebellar ablation abolishes the natural production of compound movements in the awake alert individuals.

    Full Text:The issue of Teaching physics vs Learning physics in our institutions of higher learning will be discussed. Physics is taught mainly by frontal lectures an old (and proven) method. The great advancements of the Information Age are introduced by exposing the students to vast amounts of computerized information and directing them to numerical problem solving by interacting with the computer. These modern methods have several drawbacks: 1. Students get the impression of easy material acquisition while in fact it becomes superficial. 2. There is little integration of topics that are taught in different courses. 3. Insufficient interest is built among undergraduate students to pursue studies that involve deeper thinking and independent research (namely, studies towards a doctoral degree). Learning physics is a formative process in the education of physicists, natural scientists and engineers. It must be based on discussions and exchange of ideas among the students, since understanding the studied material means being able to explain it to a colleague. Some universities in the US initiated programs of learning physics by creating an environment in which small groups of students are engaged in discussing material, jointly solving problems and jointly conducting simulated experiments. This is done under the supervision of a mentor. Suggestions for implementing this method in Israel will be discussed

    Full Text Available This qualitative ethnographic study examines a collaborative leadership model focused on learning and socially just practices within a change context of a wide educational partnership. The study analyzes a range of perspectives of novice teachers, mentor teachers, teacher educators and district superintendents on leadership and learning. The findings reveal the emergence of a coalition of leaders crossing borders at all levels of the educational system: local school level, district level and teacher education level who were involved in coterminous collaborative learning. Four categories of learning were identified as critical to leading a change in the educational system: learning in professional communities, learning from practice, learning through theory and research and learning from and with leaders. The implications of the study for policy makers as well as for practitioners are to adopt a holistic approach to the educational environment and plan a collaborative learning continuum from initial pre-service programs through professional development learning at all levels.

El objetivo de este trabajo es el de rendir un homenaje a su figura con motivo de este aniversario. Metchnikoff fue quien descubrió y describió el fenómeno de la fagocitosis y en función de ello ha sido considerado como el «padre de la inmunidad celular». En paralelo fue quien acuñó la palabra «gerontología», aplicándola al estudio del envejecimiento en toda su extensión y en cualquiera de sus formas, lo que le convirtió en un pionero del trabajo interdisciplinar. Consideraba que las bacterias intestinales generaban una autointoxicación que envenenaba nuestro organismo y que la acidificación del mismo a través de los bacilos ácidos que contienen los yogures podría contribuir a mantener la salud y a prolongar la vida.

    2013-06-01

    Full Text Available Health and social care systems are implementing fundamental changes to organizational structures and work practices in an effort to achieve integrated care. While some integration initiatives have produced positive outcomes, many have not. We reframe the concept of integration as a learning process fueled by knowledge exchange across diverse professional and organizational communities. We thus focus on the cognitive and social dynamics of learning in complex adaptive systems, and on learning behaviours and conditions that foster collective learning and improved collaboration. We suggest that the capacity to learn how to learn shapes the extent to which diverse professional groups effectively exchange knowledge and self-organize for integrated care delivery.

  20. Sustainable Agricultural Marketing Initiatives

    2015-07-01

    Full Text Available Sustainable marketing is a holistic approach that puts equal emphasis on environmental, social equity, and economic concerns in the development of marketing strategies. The purpose of the study is to examine and discuss the sustainable agricultural marketing initiatives practiced throughout the World and Turkey, and to put forth suggestions to further improve the performance of agricultural marketing initiatives in Turkey. Some of the sustainable agricultural marketing initiatives practiced around the world are carried out through civil organizations. Furthermore; some of these initiatives have also launched by farmers, consumers, food processors and retailers. The long-term strategies to increase these initiatives should be determined due to the fact that examples of successful sustainable agricultural marketing initiatives are inadequate and cannot be spread in Turkey. In this context, first of all, the supports provided by the government to improve agricultural marketing systems, such as EU funds for rural development should be compatible with the goals of sustainable marketing. For this purpose, it should be examined whether all proposed projects related to agricultural marketing meet the social, economic, and environmental principles of sustainable marketing. It is important that supporting organizations, especially civil society organisations, should take an active role for faster dissemination and adoption of sustainable agricultural marketing practices in Turkey. These organizations may provide technical assistance in preparing successful project proposals and training to farm groups. In addition, the other organizations, such as local administrations, producers' associations, cooperatives, can contribute to the success of sustainable agricultural marketing initiatives. The use of direct marketing strategies and vertical integration attempts in sustainable agricultural marketing initiatives that will likely be implemented in Turkey is

    To identify mobile computing initiatives within pharmacy education, including how devices are obtained, supported, and utilized within the curriculum. An 18-item questionnaire was developed and delivered to academic affairs deans (or closest equivalent) of 98 colleges and schools of pharmacy. Fifty-four colleges and schools completed the questionnaire for a 55% completion rate. Thirteen of those schools have implemented mobile computing requirements for students. Twenty schools reported they were likely to formally consider implementing a mobile computing initiative within 5 years. Numerous models of mobile computing initiatives exist in terms of device obtainment, technical support, infrastructure, and utilization within the curriculum. Responders identified flexibility in teaching and learning as the most positive aspect of the initiatives and computer-aided distraction as the most negative, Numerous factors should be taken into consideration when deciding if and how a mobile computing requirement should be implemented.
