    2017-04-01

    TED-Ed lessons and TED-Ed clubs are two powerful educational tools that can be used in today's school classrooms in order to create an educational environment that is engaging for the students and favors their active participation, created and fostered by TED-Ed. TED-Ed is TED's educational initiative, committed to create lessons worth sharing and amplify the voices and ideas of teachers and students around the world. TED-Ed animated lessons are fully organized lessons structured around an animated video that introduces new topics to learners in an exciting, thought-provoking way. These lessons have been created as a result of the cooperation between expert educators and animators and have been uploaded at the TED-Ed platform (http://ed.ted.com). On the other hand, TED-Ed Clubs are also an interesting way to offer students the chance, the voice and the opportunity to express their thoughts, engage actively on these matters and connect with each other, both at a local, as well as at an international level (http://ed.ted.com/clubs). By developing new TED-Ed lessons or by customizing appropriately existing animated TED-Ed lessons (translating, modifying the questions asked, introducing new discussion topics), I have created and implemented in my student-centered, didactic approach, a series of TED-ED animated lessons directly connected with the Greek national science syllabus that were used to spark students curiosity and initiate a further analytical discussion or introduce other relevant educational activities (http://gvillias.wixsite.com/education). Furthermore, at my school, we established Varvakeio TED-Ed Club, an environment that supports and empowers our students to research, develop and disseminate their own personal ideas that worth spreading. During the year, our members were inspired by watching TED talks presented by experts on their field on various different areas, including social, economical, environmental and technological-scientific issues.

    Full Text Available The aims of this research are to describe the roles of TED Talks and Vlog in enhancing students‘ activeness in speaking class and to explain the students‘ perspectives toward the use of TED Talks and Vlog in speaking class. The research method used in this research is qualitative research design in the form of case study. The instruments of data collection are documents of students‘ vlog, observation, questionnaire, and interview. The participants of this research are the students of speaking class. This research has three significances which consist of theoretical, practical, and pedagogical significances. The theoretical significance is the research contributes to prove and add the speaking theories, whereas the practical significance is the research can be conducted by teachers, lecturers, or researchers to figure out the roles and the ways to improve students‘ participation in speaking class. In addition, the pedagogical significance shows that this research provides a reference of the use TED Talks and Vlog in enhancing students‘ activeness in speaking class, helps the students to be active in speaking class by following the lecturer‘s instruction toward the speaking activities given, and can be used as the empirical research finding toward students‘ activeness in speaking class. The findings show that TED Talks and Vlog have seven roles in order to help the students to be more active in speaking class and reveal the students‘ perceptions about virtues and hurdles toward the use of TED Talks and Vlog in speaking class.

    On the afternoon of May 19 2000, a Memorial Seminar was held in the BNL physics Large Seminar Room to honor the memory of Ted Kyeia, a prominent particle physicist who had been a member of the BNL staff for 40 years. Although it was understandably a somewhat sad occasion because Ted was no longer with us, nevertheless there was much for his colleagues and friends to celebrate in recalling the outstanding contributions that he had made in those four decades. The Seminar speakers were all people who had worked with Ted during that period; each discussed one aspect of his career, but also included anecdotes and personal reminiscences. This booklet contains the Seminar program, listing the speakers, and also copies of transparencies of the talks (and one paper which was a later expansion of a talk); sadly, not all of the personal remarks appeared on the transparencies.

    Results of χ(T), M(H), and heat capacity C(T) measurements on two Ni dimer based porous materials Ni2(BODC)2(TED) and Ni2(BDC)2(TED) are reported. These materials form a tetragonal crystal structure of space group P4/ncc with a=b = 14.9 å and c = 19.4 å and Ni-Ni separation of 2.61å within the dimer. Magnetic data of Ni2(BODC)2(TED) revealed a ferromagnetic-like transition at about 17 K with θ = 8 K, and a coercivity field of 1700 G was observed in the hysteresis curve. Though isostructural to Ni2(BODC)2(TED), χ(T) and M(H) results of Ni2(BDC)2(TED) showed an antiferromagnetic transition at 10 K with θ = - 132 K, and no hysteresis was observed. Although specific heat data C(T) showed no clear transition in both compounds, nonlinear behavior is clearly seen in C/T vs. T plots, and a fit to the electron and phonon contributions to C(T) gives a large heavy-fermion-like γ in both cases. A model for the magnetic interactions is proposed and a comparison to the Cu and Co analogues is also made.

The results show that the presenters were predominately male and non-academics. Male-authored videos were more popular and more liked when viewed on YouTube. Videos by academic presenters were more commented on than videos by others and were more liked on YouTube, although there was little difference in how frequently they were viewed. The majority of academic presenters were senior faculty, males, from United States-based institutions, were visible online, and were cited more frequently than average for their field. However, giving a TED presentation appeared to have no impact on the number of citations subsequently received by an academic, suggesting that although TED popularizes research, it may not promote the work of scientists within the academic community.

    2014-05-01

    Full Text Available This paper investigates the key elements of ethos, pathos and logos linguistic strategies as some main features of TED (Technology, Entertainment, Design Talks, popularizing speeches aiming at Knowledge Dissemination. Through a comparison between the TED Talk ‘HIV - How to fight an epidemic of bad laws’, by Shereen El-Feki (2012a, and another speech held by the same author at the  2012 Symposia The Global Commission on HIV and the Law, addressed to specialists, the paper analyses TED Talks as an innovative tool of popularization, which breaches the typical triangularisation ‘scientist-mediator-audience’, bringing scientists directly into contact with their audiences. Drawing upon Aristotle’s three pillars of rhetoric, the paper analyses the strategies used to establish the ethos of the speech, by proposing a topic as morally worth of spreading; pathos, by creating a direct contact with the public; and logos, investigated through an analysis of the elements used to recontextualise scientific discourses into popularized speeches. The analysis suggests that TED Talks are a recodification, not a mere translation of texts; they are a means to disseminate knowledge reducing the asymmetry between audiences and scientists.

  10. Promotion of family-centered birth with gentle cesarean delivery.

    Science.gov (United States)

    Magee, Susanna R; Battle, Cynthia; Morton, John; Nothnagle, Melissa

    2014-01-01

    In this commentary we describe our experience developing a "gentle cesarean" program at a community hospital housing a family medicine residency program. The gentle cesarean technique has been popularized in recent obstetrics literature as a viable option to enhance the experience and outcomes of women and families undergoing cesarean delivery. Skin-to-skin placement of the infant in the operating room with no separation of mother and infant, reduction of extraneous noise, and initiation of breastfeeding in the operating room distinguish this technique from traditional cesarean delivery. Collaboration among family physicians, obstetricians, midwives, pediatricians, neonatologists, anesthesiologists, nurses, and operating room personnel facilitated the provision of gentle cesarean delivery to families requiring an operative birth. Among 144 gentle cesarean births performed from 2009 to 2012, complication rates were similar to or lower than those for traditional cesarean births. Gentle cesarean delivery is now standard of care at our institution. By sharing our experience, we hope to help other hospitals develop gentle cesarean programs. Family physicians should play an integral role in this process. © Copyright 2014 by the American Board of Family Medicine.

  11. TED analysis of the Si(113) surface structure

    1999-09-01

    We carried out a TED (transmission electron diffraction) analysis of the Si(113) surface structure. The TED patterns taken at room temperature showed reflections due to the 3×2 reconstructed structure. The TED pattern indicated that a glide plane parallel to the direction suggested in some models is excluded. We calculated the R-factors (reliability factors) for six surface structure models proposed previously. All structure models with energy-optimized atomic positions have large R-factors. After revision of the atomic positions, the R-factors of all the structure models decreased below 0.3, and the revised version of Dabrowski's 3×2 model has the smallest R-factor of 0.17.

As head of the School for 11 years, Ted Wilson became a CERN ambassador to the outside community. He retired in March, handing over the reigns of the CAS to Daniel Brandt. Ted Wilson and his assistant, Suzanne von Wartburg, during an EPAC meeting in 1994.The accelerator schools allowed some time for relaxation in the local surrounding for students as well as for the director of CAS.As a boy, Ted Wilson could have embarked on a career in pop music rather than physics, rubbing shoulders at secondary school in Liverpool with two of the future Beatles. But prefering classical music and answering the call of science, he took the more serious of the two paths, studying physics first at Oxford University then at the Rutherford Laboratory. After a year at CERN and four years at the Rutherford La...

    Cain, Jeff

    2016-12-25

    Objective. To implement and assess an elective course designed to enhance student creative thinking and presentation skills. Design. A two-credit elective course was developed that incorporated creative-thinking exercises, article discussions pertaining to creativity, TED Talk (TED Conferences, New York, NY) analyses, and presentation design and delivery exercises. Assessment. Assessment instruments included pre- and post-course Torrance Tests of Creative Thinking (TTCT). A scoring rubric was developed and used to evaluate a final mock TED Talk presented to faculty and students. Course evaluations were also used to assess student experiences in the course. Students' TTCT verbal creativity scores increased significantly ( p <0.05) during the course and their mock TED Talk mean scores (135±6.4) out of 150 were rated highly. Conclusion. The outcomes from this elective course confirmed that pharmacy students could develop and present an original "idea worth sharing" using the TED Talk format.

  16. TED: A Tolerant Edit Distance for segmentation evaluation.

    2017-02-15

    In this paper, we present a novel error measure to compare a computer-generated segmentation of images or volumes against ground truth. This measure, which we call Tolerant Edit Distance (TED), is motivated by two observations that we usually encounter in biomedical image processing: (1) Some errors, like small boundary shifts, are tolerable in practice. Which errors are tolerable is application dependent and should be explicitly expressible in the measure. (2) Non-tolerable errors have to be corrected manually. The effort needed to do so should be reflected by the error measure. Our measure is the minimal weighted sum of split and merge operations to apply to one segmentation such that it resembles another segmentation within specified tolerance bounds. This is in contrast to other commonly used measures like Rand index or variation of information, which integrate small, but tolerable, differences. Additionally, the TED provides intuitive numbers and allows the localization and classification of errors in images or volumes. We demonstrate the applicability of the TED on 3D segmentations of neurons in electron microscopy images where topological correctness is arguable more important than exact boundary locations. Furthermore, we show that the TED is not just limited to evaluation tasks. We use it as the loss function in a max-margin learning framework to find parameters of an automatic neuron segmentation algorithm. We show that training to minimize the TED, i.e., to minimize crucial errors, leads to higher segmentation accuracy compared to other learning methods. Copyright © 2016. Published by Elsevier Inc.

  17. The Pathophysiology of Thyroid Eye Disease (TED): Implications for Immunotherapy

    Gupta, Shivani; Douglas, Raymond

    2012-01-01

    Purpose of Review Thyroid eye disease (TED) is a poorly understood autoimmune manifestation most commonly associated with Graves’ disease. Current nonspecific treatment paradigms offer symptomatic improvement but fail to target the underlying pathogenic mechanisms and thus, do not significantly alter the long-term disease outcome. The purpose of this review is to provide an update of the current understanding of the immunopathogenesis of TED and explore these implications for targeted immunotherapy. Recent Findings Orbital fibroblasts are integral to the pathogenesis of TED and may modulate immune responses by production of cytokines and hyaluronan in response to activation of shared autoantigens including thyrotropin receptor (TSHR) and insulin-like growth factor-1 receptor (IGF-R1). Fibrocytes share many of these phenotypic and functional features, suggesting a link between systemic and site-specific disease. Use of targeted immunotherapies in TED is limited, though data from the use Rituximab (RTX), a B cell depleting agent, are encouraging. Sustained clinical response has been seen with RTX in several reports, despite return of peripheral B cell levels to pretreatment levels. Additionally, this response appears to be independent to cytokine and antibody production, suggesting possible modulation of antigen presentation as a mechanism of its effect. Summary Progressive advances in the understanding of the immunopathogenesis of TED continue to spur clinical trials utilizing targeted immune therapies. Continued understanding of the molecular mechanisms of disease will expand potential treatments for TED patients and obviate the need for reconstructive surgical therapies. PMID:21730841

    Long before technology assessment and continuous quality improvement were in vogue in chiropractic, Ted L. Shrader, D.C., F.I.C.C., was working toward these goals in the profession. Convinced that chiropractic must change from within for the benefit of society, Dr. Shrader has made a career-long commitment to evaluating chiropractic procedures and establishing consensus statements regarding chiropractic principle. Determined in mind, moral by nature, and unobtrusive in manner, Dr. Shrader has been decidedly effective in his endeavors. He has encouraged in chiropractic a mind for critical thinking. The fruits of his labor can be seen today in chiropractic publication, among chiropractic scholars, within the American Chiropractic Association Council on Technique, in conference proceedings, and in our institutions.

    2014-04-01

    To assess impaired quality of life (QOL) of Korean patients with thyroid eye disease (TED) using the TED-QOL questionnaire, to evaluate the adaptability of the questionnaire, and to assess the correlation between TED-QOL and scales of disease severity. Prospective, cross-sectional study. Total of 90 consecutive adult patients with TED and Graves' disease were included in this study. TED-QOL was translated into Korean and administered to the patients. The results were compared with clinical severity scores (clinical activity score, VISA (vision loss (optic neuropathy); inflammation; strabismus/motility; appearance/exposure) classification, modified NOSPECS (no signs or symptoms; only signs; soft tissue; proptosis; extraocular muscle; cornea; sight loss) score, Gorman diplopia scale, and European Group of Graves' Orbitopathy Classification). Clinical scores indicating inflammation and strabismus in patients with TED were positively correlated with overall and visual function-related QOL (Spearman coefficient 0.21-0.38, p < 0.05). Clinical scores associated with appearance were positively correlated with appearance-related QOL (Spearman coefficient 0.26-0.27, p < 0.05). In multivariate analysis, age, soft-tissue inflammation, motility disorder of modified NOSPECS, and motility disorder of VISA classification had positive correlation with overall and function-related QOL. Sex, soft-tissue inflammation, proptosis of modified NOSPECS, and appearance of VISA classification had correlation with appearance-related QOL. In addition, validity of TED-QOL was proved sufficient based on the outcomes of patient interviews and correlation between the subscales of TED-QOL. TED-QOL showed significant correlations with various objective clinical parameters of TED. TED-QOL was a simple and useful tool for rapid evaluation of QOL in daily outpatient clinics, which could be readily translated into different languages to be widely applicable to various populations.

    2005-04-01

    The vibration-rotation emission spectra for the X2Π ground state and the near infrared emission spectra of the X2Π 1/2- X2Π 3/2 system of the TeH and TeD free radicals have been measured at high resolution using a Fourier transform spectrometer. TeH and TeD were generated in a tube furnace with a DC discharge of a flowing mixture of argon, hydrogen (or deuterium), and tellurium vapor. In the infrared region, for the X2Π 3/2 spin component we observed the 1-0, 2-1, and 3-2 vibrational bands for most of the eight isotopologues of TeH and the 1-0 and 2-1 bands for three isotopologues of TeD. For the X2Π 1/2- X2Π 3/2 transition, we observed the 0-0 and 1-1 bands for TeH and the 0-0, 1-1, and 2-2 bands for TeD. Except for a few lines, the tellurium isotopic shift was not resolved for the X2Π 1/2- X2Π 3/2 transitions of TeH and TeD. Local perturbations with Δ v = 2 between the two spin components of the X2Π state of TeH were found: X2Π 1/2, v = 0 with X2Π 3/2, v = 2; X2Π 1/2, v = 1 with X2Π 3/2, v = 3. The new data were combined with the previous data from the literature and two kinds of fits (Hund's case (a) and Hund's case (c)) were carried out for each of the 10 observed isotopologues: 130TeD, 128TeD, 126TeD, 130TeH, 128TeH, 126TeH, 125TeH, 124TeH, 123TeH, and 122TeH.

  8. Sensitivity and responsiveness of the patient-reported TED-QOL to rehabilitative surgery in thyroid eye disease.

    2016-12-01

    We tested the sensitivity and responsiveness of the TED-QOL to rehabilitative surgery in thyroid eye disease (TED). The 3-item TED-QOL and 16-item GO-QOL, which assess quality of life (QoL) in TED, were administered to consecutive patients undergoing rehabilitative surgery. The questionnaires were completed pre-and post-operatively to assess sensitivity (ability to discriminate between different surgical groups) and responsiveness (ability to detect within patient changes over time).56 patients underwent 69 procedures for TED (29 orbital decompressions, 15 strabismus operations, 25 eyelid procedures). The differences in scores between the three types of surgery (a measure of sensitivity) were statistically significant at the 5% level pre-operatively and post-operatively for all 3 TED-QOL scales and for both GO-QOL scales, but much more so for the TED-QOL scales in each case. The within-patient changes between the pre- and post-operative scores for the same subjects (a measure of responsiveness) were statistically very highly significant for the TED-QOL overall and appearance scales for each of the surgeries. The pre- and post-operative difference for the TED-QOL functioning scale was highly statistically significant for strabismus surgery but not for decompression or lid surgery. The change between the pre- and post-operative scores for the GO-QOL was significant for the functioning scale with strabismus and lid surgery, and was highly significant for the appearance scale with lid surgery but not for strabismus surgery or decompression. The 3-item TED-QOL is sensitive and responsive to rehabilitative surgery in TED and compares favorably with the lengthier GO-QOL for these parameters.

  9. Obituary: Edward R. (Ted) Harrison, 1919-2007

    Science.gov (United States)

    Irvine, William M.; Arny, Thomas T.; Trimble, Virginia

    2007-12-01

    Cosmologist Edward R. (Ted) Harrison, emeritus Distinguished University Professor of Physics and Astronomy at the University of Massachusetts Amherst, died on 29 January 2007 in his retirement city of Tucson, Arizona, where he was adjunct professor at the Steward Observatory, University of Arizona. The cause of death was colon cancer. He is survived by a sister, brother, and daughter. (A son died in 2000.) Perhaps best known for his work on the growth of fluctuations in the expanding universe and his books on cosmology for the dedicated layperson, Ted had extremely broad interests, and he published more than 200 papers in space sciences, plasma physics, high-energy physics, physical chemistry, and, principally, many aspects of astrophysics. He was a Fellow of the American Physical Society, the American Association for the Advancement of Science, the Royal Astronomical Society, and the Institute of Physics (UK). Ted Harrison was born 8 January 1919 in London, England. His parents were Robert Harrison and Daisy Harrison (nee White). His education at Sir John Cass College, London University, was interrupted by the Second World War, during which he served for six years with the British Army in various campaigns, ultimately acting as Radar Adviser to the Northern Area of the Egyptian Army. It was during the latter service that he met his wife Photeni (nee Marangas). Following the War, Ted became a British Civil Servant, at first with the Atomic Energy Research Establishment in Harwell and then at the Rutherford High Energy Laboratory. During this period he acquired the equivalent of university degrees, becoming a graduate, then an Associate, and finally a Fellow of the Institute of Physics. His somewhat unorthodox education may have contributed to his broad interests and his very intuitive and physical approach to scientific problems. The latter became the bane of generations of graduate students, who might find themselves asked on their physics qualifying exams to

    A TED study of Si(113) surfaces was carried out. Reflections from the 3 × 2 reconstruction were seen at room temperature, while half-order reflections were very faint. The surface showed the phase transition between the 3 × 1 and the disordered (rough) structures at about 930°C. The (113) surface structure at room temperature was analyzed using TED intensity. Four kinds of structure models proposed previously, including both the 3 × 1 and the 3 × 2 reconstructed structures, were examined. The R-factors calculated using the energy-optimized atomic coordinates are not sufficiently small. After minimization of the R-factors, Dabrowski's 3 × 2 structure model is most agreeable, while Ranke's 3 × 1 and 3 × 2 structure models are not to be excluded. STM observation showed that the surface is composed of small domains of the 3 × 2 structure.

    The TED (Technology, Entertainment, Design) Talks website hosts video recordings of various experts, celebrities, academics, and others who discuss their topics of expertise. Funded by advertising and members but provided free online, TED Talks have been viewed over a billion times and are a science communication phenomenon. Although the organization has been derided for its populist slant and emphasis on entertainment value, no previous research has assessed audience reactions in order to determine the degree to which presenter characteristics and platform affect the reception of a video. This article addresses this issue via a content analysis of comments left on both the TED website and the YouTube platform (on which TED Talks videos are also posted). It was found that commenters were more likely to discuss the characteristics of a presenter on YouTube, whereas commenters tended to engage with the talk content on the TED website. In addition, people tended to be more emotional when the speaker was a woman (by leaving comments that were either positive or negative). The results can inform future efforts to popularize science amongst the public, as well as to provide insights for those looking to disseminate information via Internet videos.

    Full Text Available Abstract – This study explores the web-mediated genre of TED (Technology, Entertainment, Design talks, speech events whereby experts in their field disseminate knowledge from different domains (e.g. science, technology, design, global issues addressing an audience of both co-present participants and web-users all over the world. The aim of this study is to investigate the way academics convey epistemic stance (Conrad, Biber 2000 and build up their image as experts on the TED stage. To this purpose, a contrastive analysis was carried out comparing two corpora of spoken discourse, i.e. a corpus of TED talks and a corpus of MICASE university lectures from different disciplines. Although in both genres the speaker is an academic, both the communicative purpose and audience expectations differ substantially in the two contexts under scrutiny. This comparison highlights some distinguishing traits of TED talks and provides a better insight into this genre. Adopting a corpus-based approach, attention is first paid to the most recurrent epistemic lexical verbs (ELVs and to the use of first and second person pronouns in the two corpora. The qualitative analysis then focuses on similarities and differences in the discourse functions of the four most frequent ELVs (see, show, know, think and of their clusters when they combine with first and second person pronouns in the two corpora. Previous studies in the field of English for Academic Purposes (Rounds 1987; Fortanet 2004; Walsh 2004; Artiga León 2006; Bamford 2009 are referred to as a starting point to investigate a novel, unexplored pragmatic space (i.e. that of TED wherein academics accomplish purposes other than merely disseminating knowledge and training students, such as promoting their research and building up their image as experts.

    MITE, TRIM and SINEs are miniature form transposable elements (mTEs) that are ubiquitous and dispersed throughout entire plant genomes. Tens of thousands of members cause insertion polymorphism at both the inter- and intra- species level. Therefore, mTEs are valuable targets and resources for development of markers that can be utilized for breeding, genetic diversity and genome evolution studies. Taking advantage of the completely sequenced genomes of Brassica rapa and B. oleracea, characterization of mTEs and building a curated database are prerequisite to extending their utilization for genomics and applied fields in Brassica crops. We have developed BrassicaTED as a unique web portal containing detailed characterization information for mTEs of Brassica species. At present, BrassicaTED has datasets for 41 mTE families, including 5894 and 6026 members from 20 MITE families, 1393 and 1639 members from 5 TRIM families, 1270 and 2364 members from 16 SINE families in B. rapa and B. oleracea, respectively. BrassicaTED offers different sections to browse structural and positional characteristics for every mTE family. In addition, we have added data on 289 MITE insertion polymorphisms from a survey of seven Brassica relatives. Genes with internal mTE insertions are shown with detailed gene annotation and microarray-based comparative gene expression data in comparison with their paralogs in the triplicated B. rapa genome. This database also includes a novel tool, K BLAST (Karyotype BLAST), for clear visualization of the locations for each member in the B. rapa and B. oleracea pseudo-genome sequences. BrassicaTED is a newly developed database of information regarding the characteristics and potential utility of mTEs including MITE, TRIM and SINEs in B. rapa and B. oleracea. The database will promote the development of desirable mTE-based markers, which can be utilized for genomics and breeding in Brassica species. BrassicaTED will be a valuable repository for scientists

  4. Acute thyroid eye disease (TED): principles of medical and surgical management.

    Science.gov (United States)

    Verity, D H; Rose, G E

    2013-03-01

    The active inflammatory phase of thyroid eye disease (TED) is mediated by the innate immune system, and management is aimed at aborting this self-limited period of autoimmune activity. In most patients with TED, ocular and adnexal changes are mild and management involves controlling thyroid dysfunction, cessation of smoking, and addressing ocular surface inflammation and exposure. In patients with acute moderate disease, this being sufficient to impair orbital functions, immunosuppression reduces the long-term sequelae of acute inflammation, and adjunctive fractionated low-dose orbital radiotherapy is used as a steroid-sparing measure. Elective surgery is often required following moderate TED, be it for proptosis, diplopia, lid retraction, or to debulk the eyelid, and this should be delayed until the disease is quiescent, with the patient stable and weaned off all immunosuppression. Thus, surgical intervention during the active phase of moderate disease is rarely indicated, although clinical experience suggests that, where there is significant orbital congestion, early orbital decompression can limit progression to more severe disease. Acute severe TED poses a major risk of irreversible loss of vision due to marked exposure keratopathy, 'hydraulic' orbital congestion, or compressive optic neuropathy. If performed promptly, retractor recession with or without a suture tarsorrhaphy protects the ocular surface from severe exposure and, in patients not responding to high-dose corticosteroid treatment, decompression of the deep medial orbital wall and floor can rapidly relieve compressive optic neuropathy, as well as alleviate the inflammatory and congestive features of raised orbital pressure.

  5. TED, an autonomous and rare maize transposon of the mutator superfamily with a high gametophytic excision frequency.

    Li, Yubin; Harris, Linda; Dooner, Hugo K

    2013-09-01

    Mutator (Mu) elements, one of the most diverse superfamilies of DNA transposons, are found in all eukaryotic kingdoms, but are particularly numerous in plants. Most of the present knowledge on the transposition behavior of this superfamily comes from studies of the maize (Zea mays) Mu elements, whose transposition is mediated by the autonomous Mutator-Don Robertson (MuDR) element. Here, we describe the maize element TED (for Transposon Ellen Dempsey), an autonomous cousin that differs significantly from MuDR. Element excision and reinsertion appear to require both proteins encoded by MuDR, but only the single protein encoded by TED. Germinal excisions, rare with MuDR, are common with TED, but arise in one of the mitotic divisions of the gametophyte, rather than at meiosis. Instead, transposition-deficient elements arise at meiosis, suggesting that the double-strand breaks produced by element excision are repaired differently in mitosis and meiosis. Unlike MuDR, TED is a very low-copy transposon whose number and activity do not undergo dramatic changes upon inbreeding or outcrossing. Like MuDR, TED transposes mostly to unlinked sites and can form circular transposition products. Sequences closer to TED than to MuDR were detected only in the grasses, suggesting a rather recent evolutionary split from a common ancestor.

  7. Patterns of clusivity in TED Talks: When ‘ you ’ and ‘I’ become ‘ we’

    2018-04-01

    Full Text Available This paper is a qualitative and quantitative corpus-based study analysing the correlation of clusivity, tense, and modality patterns in TED (Technology, Entertainment, Design talks, which are popularising speeches aiming at knowledge dissemination among laypersons. Using a corpus composed of the TED Talks presented in 2012, the study investigates the ways in which TED speakers use first-person plural and singular pronouns when interacting with their audiences. The patterns of clusivity used in the corpus confirm one of the main characteristics of TED Talks, that is to say, the abolition of the ‘scientistmediator-audience’ triangulation, typical of canonical popularising genres. The inclusive pronouns used in the corpus construct positive politeness, making the audience feel part of the knowledge-spreading experience. The analysis also reveals how TED Talks are actually an ‘innovative’ means of popularisation, in which there is no longer a distinction between ‘I’, the speaker, and ‘you’, the audience. ‘I’ and ‘you’ become ‘we’, in a common project which invites the audience to take on specific attitudes and behaviours and concretely participate in changes.

  12. Ted Irving and the Arc of APW Paths

    Kent, D. V.

    2014-12-01

    Ted Irving's last two published papers neatly encapsulate his seminal contributions to the delineation of ever-important apparent polar wander (APW) paths. His final (210th) paper [Creer & Irving, 2012 Earth Sciences History] describes in detail how Ken Creer and he when still graduate students at Cambridge started to generate and assemble paleomagnetic data for the first APW path, for then only the UK; the paper was published 60 years ago and happened to be Ted's first [Creer, Irving & Runcorn, 1954 JGE]. Only 10 years later, there was already a lengthy reference list of paleomagnetic results available from most continents that had been compiled in pole lists he published in GJRAS from 1960 to 1965 and included in an appendix in his landmark book "Paleomagnetism" [Irving, 1964 Wiley] in support of wide ranging discussions of continental drift and related topics in chapters like 'Paleolatitudes and paleomeridians.' A subsequent innovation was calculating running means of poles indexed to a numerical geologic time scale [Irving, 1977 Nature], which with independent tectonic reconstructions as already for Gondwana allowed constructions of more detailed composite APW paths. His 1977 paper also coined Pangea B for an earlier albeit contentious configuration for the supercontinent that refuses to go away. Gliding over much work on APW tracks and hairpins in the Precambrian, we come to Ted's penultimate (209th) paper [Kent & Irving, 2010 JGR] in which individual poles from short-lived large igneous provinces were grouped and most sedimentary poles, many rather venerable, excluded as likely to be biased by variable degrees of inclination error. The leaner composite APW path helped to resurrect the Baja BC scenario of Cordilleran terrane motions virtually stopped in the 1980s by APW path techniques that relied on a few key but alas often badly skewed poles. The new composite APW path also revealed several major features, such as a huge polar shift of 30° in 15 Myr in the

  18. SU-E-I-68: Practical Considerations On Implementation of the Image Gently Pediatric CT Protocols

    Zhang, J; Adams, C; Lumby, C; Dillon, J; Woods, E; Richer, E

    2014-01-01

    Purpose: One limitation associated with the Image Gently pediatric CT protocols is practical implementation of the recommended manual techniques. Inconsistency as a result of different practice is a possibility among technologist. An additional concern is the added risk of data error that would result in over or underexposure. The Automatic Exposure Control (AEC) features automatically reduce radiation for children. However, they do not work efficiently for the patients of very small size and relative large size. This study aims to implement the Image Gently pediatric CT protocols in the practical setting while maintaining the use of AEC features for pediatric patients of varying size. Methods: Anthropomorphological abdomen phantoms were scanned in a CT scanner using the Image Gently pediatric protocols, the AEC technique with a fixed adult baseline, and automatic protocols with various baselines. The baselines were adjusted corresponding to patient age, weight and posterioranterior thickness to match the Image Gently pediatric CT manual techniques. CTDIvol was recorded for each examination. Image noise was measured and recorded for image quality comparison. Clinical images were evaluated by pediatric radiologists. Results: By adjusting vendor default baselines used in the automatic techniques, radiation dose and image quality can match those of the Image Gently manual techniques. In practice, this can be achieved by dividing pediatric patients into three major groups for technologist reference: infant, small child, and large child. Further division can be done but will increase the number of CT protocols. For each group, AEC can efficiently adjust acquisition techniques for children. This implementation significantly overcomes the limitation of the Image Gently manual techniques. Conclusion: Considering the effectiveness in clinical practice, Image Gently Pediatric CT protocols can be implemented in accordance with AEC techniques, with adjusted baselines, to

  1. Stance in TED talks: Strategic use of subjective adjectives in online popularisation

    Directory of Open Access Journals (Sweden)

    Giuseppina Scotto di Carlo

    2015-04-01

    Full Text Available This paper analyses “stance” in TED (Technology, Entertainment, Design talks, which are popularising speeches aiming at knowledge dissemination. Based on a corpus of the TED talks presented between 2006 and 2012, this study focuses on how the speakers express judgments and take up positions through subjective adjectives. Drawing upon Kerbat-Orecchioni (1980 and Felices Lago’s (1997 adjective classifications, the quantitative and qualitative study attempts to analyse the use of axiological evaluative adjectives, which are fully subjective, as they imply a qualitative evaluation adding a judgement to the modified noun. It has been noticed that TEDsters use vivid, descriptive subjective adjectives to establish a connection with the audience, which perceives a sense of similarity with the speaker. Like traditional scientific presentations, TED talks use adjectives conveying the relevance of their findings, while they distinguish themselves for the role given to aesthetic and emotional adjectives, practicality and veracity, also including the moral, political, and economic aspects involved in science. The work suggests that maybe TEDsters’ approach to science might possibly contribute to breach the expert/non expert barrier, considering science not as something distant, but as a human experience for both laypersons and professionals.

    Fayers, Tessa; Dolman, Peter J

    2011-12-01

    To develop and test a user-friendly questionnaire for rapidly assessing quality of life (QOL) in thyroid eye disease (TED). A three-item questionnaire, the TED-QOL, was designed and compared to the 16-item Graves Ophthalmopathy (GO)-QOL and the nine-item GO-Quality of Life Scale (QLS). 100 patients with TED were administered all three questionnaires on two occasions. Results were compared to clinical severity scores (Vision, Inflammation, Strabismus, Appearance (VISA) classification). Main outcomes were construct and criterion validity, test-retest reliability, duration, comprehension and completion rates. TED-QOL correlated strongly with the other questionnaires for corresponding items (Pearson correlation: appearance 0.71, 0.62; functioning 0.69, 0.66; overall QOL 0.53). Test-retest analysis demonstrated good reliability for all three questionnaires (intraclass correlations: TED-QOL 0.81, 0.74, 0.87; GO-QOL 0.81, 0.82; GO-QLS 0.74, 0.86, 0.67). TED-QOL was significantly faster to complete (1.6 min vs GO-QOL 3.1 min, GO-QLS 2.7 min, p<0.0001) and had a higher completion rate (100% vs GO-QOL 78%, GO-QLS 94%). There was only moderate correlation between items on all three questionnaires and VISA scores. The TED-QOL is rapid and easy to complete and analyse and has similar validity and reliability to longer questionnaires. All questionnaires showed only moderate correlation with disease severity, emphasising the discrepancy between objective and subjective assessments and the importance of measuring both.

  6. Combination TLD/TED dose assessment

    International Nuclear Information System (INIS)

    Parkhurst, M.A.

    1992-11-01

    During the early 1980s, an appraisal of dosimetry programs at US Department of Energy (DOE) facilities identified a significant weakness in dose assessment in fast neutron environments. Basing neutron dose equivalent on thermoluminescence dosimeters (TLDS) was not entirely satisfactory for environments that had not been well characterized. In most operational situations, the dosimeters overrespond to neutrons, and this overresponse could be further exaggerated with changes in the neutron quality factor (Q). Because TLDs are energy dependent with an excellent response to thermal and low-energy neutrons but a weak response to fast neutrons, calibrating the dosimetry system to account for mixed and moderated neutron energy fields is a difficult and seldom satisfactory exercise. To increase the detection of fast neutrons and help improve the accuracy of dose equivalent determinations, a combination dosimeter was developed using TLDs to detect thermal and low-energy neutrons and a track-etch detector (TED) to detect fast neutrons. By combining the albedo energy response function of the TLDs with the track detector elements, the dosimeter can nearly match the fluence-to-dose equivalent conversion curve. The polymer CR-39 has neutron detection characteristics superior to other materials tested. The CR-39 track detector is beta and gamma insensitive and does not require backscatter (albedo) from the body to detect the exposure. As part of DOE's Personnel Neutron and Upgrade Program, we have been developing a R-39 track detector over the past decade to address detection and measurement of fast neutrons. Using CR-39 TEDs in combination with TLDs will now allow us to detect the wide spectrum of occupational neutron energies and assign dose equivalents much more confidently

  7. Effect of gentle stroking and vocalization on behaviour, mucosal immunity and upper respiratory disease in anxious shelter cats.

    2014-11-01

    Emotional, behavioural, and health benefits of gentle stroking and vocalizations, otherwise known as gentling, have been documented for several species, but little is known about the effect of gentling on cats in stressful situations. In this study, 139 cats rated as anxious upon admission to an animal shelter were allocated to either a Gentled or Control group. Cats were gentled four times daily for 10 min over a period of 10 days, with the aid of a tool for cats that were too aggressive to handle. The cats' mood, or persistent emotional state, was rated daily for 10 d as Anxious, Frustrated or Content. Gentled cats were less likely to have negatively valenced moods (Anxious or Frustrated) than Control cats (Incidence Rate Ratio [IRR]=0.61 CI 0.42-0.88, P=0.007). Total secretory immunoglobulin A (S-IgA) was quantified from faeces by enzyme-linked immunosorbent assay. Gentled cats had increased S-IgA (6.9 ± 0.7 logeμg/g) compared to Control cats (5.9 ± 0.5 logeμg/g) (Pincrease in shedding over time in Control cats (23%, 35%, 52% on days 1, 4 and 10, respectively), but not in gentled cats (32%, 26%, 30% on days 1, 4 and 10, respectively) (P=0.001). Onset of upper respiratory disease was determined by veterinary staff based on clinical signs, in particular ocular and/or nasal discharge. Control cats were 2.4 (CI: 1.35-4.15) times more likely to develop upper respiratory disease over time than gentled cats (Pincrease production of S-IgA, and reduce the incidence of upper respiratory disease.

  8. Proteolytic Processing and Assembly of gag and gag-pol Proteins of TED, a Baculovirus-Associated Retrotransposon of the Gypsy Family

    Science.gov (United States)

    Hajek, Kathryn L.; Friesen, Paul D.

    1998-01-01

    TED (transposable element D) is an env-containing member of the gypsy family of retrotransposons that represents a possible retrovirus of invertebrates. This lepidopteran (moth) retroelement contains gag and pol genes that encode proteins capable of forming viruslike particles (VLP) with reverse transcriptase. Since VLP are likely intermediates in TED transposition, we investigated the roles of gag and pol in TED capsid assembly and maturation. By using constructed baculovirus vectors and TED Gag-specific antiserum, we show that the principal translation product of gag (Pr55gag) is cleaved to produce a single VLP structural protein, p37gag. Replacement of Asp436 within the retrovirus-like active site of the pol-encoded protease (PR) abolished Pr55gag cleavage and demonstrated the requirement for PR in capsid processing. As shown by expression of an in-frame fusion of TED gag and pol, PR is derived from the Gag-Pol polyprotein Pr195gag-pol. The PR cleavage site within Pr55gag was mapped to a position near the junction of a basic, nucleocapsid-like domain and a C-terminal acidic domain. Once released by cleavage, the C-terminal fragment was not detected. This acidic fragment was dispensable for VLP assembly, as demonstrated by the formation of VLP by C-terminal Pr55gag truncation proteins and replacement of the acidic domain with a heterologous protein. In contrast, C-terminal deletions that extended into the adjacent nucleocapsid-like domain of Pr55gag abolished VLP recovery and demonstrated that this central region contributes to VLP assembly or stability, or both. Collectively, these data suggest that the single TED protein p37gag provides both capsid and nucleocapsid functions. TED may therefore use a simple processing strategy for VLP assembly and genome packaging. PMID:9765414

    Full Text Available Identifying scents in a wine’s bouquet is considered one of the most important steps in the process of wine tasting. An individual’s ability to successfully do this is dependent on the sense of smell; thus, altering the nasal microenvironment could have a powerful effect on the wine tasting experience. In the present study, we examined olfactory performance in healthy participants who cleared their nasal cavity before odorant presentations. Fifty undergraduate participants were assessed with a standardized test of olfaction requiring the recognition of a battery of odors. Half of these participants cleared mucus from their nasal cavities (by gently blowing their noses prior to the assessment. No difference was found in performance between those who cleared their nasal passages and those who did not. Further, data were not different than known population data from the test. These data suggest that gently clearing the nasal cavity before presentation of odorants bears no effect on the ability to perceive those odor qualities.

  15. 14N NQR study of hydrogen bonded complexes of 1,4 diazabicyclo [2,2,2] octane (ted) with phenols and thiourea

    Science.gov (United States)

    Murgich, Juan; Magaly, Santana R.; Diaz, Olga E.

    The 14N NQR spectra of H bonded complexes of 1,4 diazabicyclo [2,2,2] octane, also known as triethylenediamine (TED), with phenol (1:2), p-chlorophenol (1:2), p-nitrophenol (1:2), hydroquinone (1:1), resorcinol (1:1) and thiourea (1:2) were observed at 77 K. The 14N frequency shifts produced by the H bonds in the TED complexes were approximately two times larger than those found for similar complexes of Hexamethylenetetramine (HMT). Such change was explained by the effect on the remaining N atoms of the increase in the number of -CH 2- groups and the decrease in N atoms in passing from HMT to TED. From the above results it seems that the inductive effect plays an important role in the formation of H bonds in tertiary amines like HMT and TED.

  16. Direct Imaging of ER Calcium with Targeted-Esterase Induced Dye Loading (TED)

    Samtleben, Samira; Jaepel, Juliane; Fecher, Caroline; Andreska, Thomas; Rehberg, Markus; Blum, Robert

    2013-01-01

    Visualization of calcium dynamics is important to understand the role of calcium in cell physiology. To examine calcium dynamics, synthetic fluorescent Ca2+ indictors have become popular. Here we demonstrate TED (= targeted-esterase induced dye loading), a method to improve the release of Ca2+ indicator dyes in the ER lumen of different cell types. To date, TED was used in cell lines, glial cells, and neurons in vitro. TED bases on efficient, recombinant targeting of a high carboxylesterase activity to the ER lumen using vector-constructs that express Carboxylesterases (CES). The latest TED vectors contain a core element of CES2 fused to a red fluorescent protein, thus enabling simultaneous two-color imaging. The dynamics of free calcium in the ER are imaged in one color, while the corresponding ER structure appears in red. At the beginning of the procedure, cells are transduced with a lentivirus. Subsequently, the infected cells are seeded on coverslips to finally enable live cell imaging. Then, living cells are incubated with the acetoxymethyl ester (AM-ester) form of low-affinity Ca2+ indicators, for instance Fluo5N-AM, Mag-Fluo4-AM, or Mag-Fura2-AM. The esterase activity in the ER cleaves off hydrophobic side chains from the AM form of the Ca2+ indicator and a hydrophilic fluorescent dye/Ca2+ complex is formed and trapped in the ER lumen. After dye loading, the cells are analyzed at an inverted confocal laser scanning microscope. Cells are continuously perfused with Ringer-like solutions and the ER calcium dynamics are directly visualized by time-lapse imaging. Calcium release from the ER is identified by a decrease in fluorescence intensity in regions of interest, whereas the refilling of the ER calcium store produces an increase in fluorescence intensity. Finally, the change in fluorescent intensity over time is determined by calculation of ΔF/F0. PMID:23685703

    2017-10-01

    Full Text Available Constructivism is defined as building one’s own understanding. Constructivist instructional method requires that teacher should not be the one who informs but who facilitates the students learning. The purpose of this study is to obtain the students’ perceptions on the implementation of constructivist instructional methods in Teaching and Learning course. A survey research methodology was used with first semester students who were taking teaching and learning course as the subjects of this study. Methods of collecting data were questionnaires with open ended questions, deep interview and documentation. A qualitative analysis technique was performed on data from the survey instrument and the interview to answer 4 research questions. A descriptive analysis technique was performed on data to answer 1 research question from the survey instrument and documents. The data analysis revealed that constructivism instructional methods were clearly experienced when they were required to answer a lot of probing questions, had discussion in the classroom, had Facebook online discussions with clear guidance to do so, created ted talks and debating.The study implies that the constructivist instructional methods experienced by the students in the class help them to better understand the constructivism theory and its implications.

    2006-09-01

    While surgical tracheotomies are currently performed using state-of-the-art operative techniques, percutaneous dilatational tracheostomy (PDT) is in a rapidly evolving state with regard to its technology and the number of techniques available. This has resulted in a range of new complications that are difficult to quantify on a scientific basis, given the fact that more than half of the patients who are tracheotomized in intensive care units die from their underlying disease. The new Tracheotomy Endoscope (TED) is designed to help prevent serious complications in dilatational tracheotomies and facilitate their management. The endoscope has been specifically adapted to meet the require-ments of percutaneous dilatational tracheotomies. It is fully compatible with all current techniques of PDT. The method is easy to learn. The percutaneous dilatational tracheotomy with the Tracheotomy Endoscope is a seven-step procedure: Advantages of the Tracheotomy Endoscope: Injuries to the posterior tracheal wall ar impossible (tracheoesophageal fistulas, pneumothorax). Minor bleeding sites on the tracheal mucosa can be controlled with a specially curved suction-coagulation tube introudeced through the Tracheotomy Endoscope. In cases with heavy bleeding and a risk of aspiration, the rigid indwelling Tracheotomy Endoscope provides a secure route for reintubating the patient with a cuffed endotracheal tube. It also allows for rapid conversion to an open surgical procedure if necessary. All the parts are easy to clean and are autoclavable. This type of endoscopically guided PDT creates an optimal link between the specialties of intensive care medicine and otorhinolaryngology. The Tracheotomy Endoscope (TED) increases the standard of safety in PDT.

    Audience response (AR) systems are increasingly used in undergraduate medical education. However, high costs and complexity of conventional AR systems often limit their use. Here we present a novel AR system that is platform independent and does not require hardware clickers or additional software to be installed. "OnlineTED" was developed at Technische Universität München (TUM) based on Hypertext Preprocessor (PHP) with a My Structured Query Language (MySQL)-database as server- and Javascript as client-side programming languages. "OnlineTED" enables lecturers to create and manage question sets online and start polls in-class via a web-browser. Students can participate in the polls with any internet-enabled device (smartphones, tablet-PCs or laptops). A paper-based survey was conducted with undergraduate medical students and lecturers at TUM to compare "OnlineTED" with conventional AR systems using clickers. "OnlineTED" received above-average evaluation results by both students and lecturers at TUM and was seen on par or superior to conventional AR systems. The survey results indicated that up to 80% of students at TUM own an internet-enabled device (smartphone or tablet-PC) for participation in web-based AR technologies. "OnlineTED" is a novel web-based and platform-independent AR system for higher education that was well received by students and lecturers. As a non-commercial alternative to conventional AR systems it may foster interactive teaching in undergraduate education, in particular with large audiences.

    Yuen, Tan; Danilovic, D.; Li, Kunhao; Li, Jing

    2008-04-01

    A new material [Ni2(BODC)2(TED)], (BODC =4,4'-bicyclo[2.2.2]octane dicarboxylate and TED =triethylene-4,4'-diamine), which is a guest-free, porous metal-organic coordination network, has been successfully synthesized. The crystal structure of this compound is tetragonal with the space group P4/mmm. It is a three-dimensional network that can be deconstructed into rectangular gridlike layers along ab planes. These planes are formed by BODC and Zn2O4 paddle-wheel-like clusters, and the TED ligands from the axial directions of the paddle-wheels connect the layers into a three-dimesional structure. There are no guest molecules found in the pores. The shortest Ni-Ni distance within the paddle wheel is found to be 2.613Å. Magnetic susceptibility χ(T )=M(T)/H and isothermal magnetization M(H ) measurements have been measured on powder samples of this compound. The results of χ(T ) show that there is a rapid increase in the susceptibility below 20K due to a spontaneous ordering of the Ni2+ moments. The effective moment μeff of Ni2+ is about 2.20μB at room temperature. The M(H ) result at 1.8K shows a clear hysteresis with a coercivity of Hcoe≈1700G. The behavior of this compound is discussed in terms of Ni-Ni coupling within the Ni dimers and dimer chains.

  12. Effects of gentling on behavior and meat quality of lambs

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Within few hours after parturition lambs develop a strong and selective relationship with their mothers (Poindron and Le Neindre, 1980. In order to increase the amount of milk available for transformation, lambs often are prematurely separated from the ewes, thus inducing an early disruption of the mother-young relationship. A number of authors demonstrated that the lack of the maternal bond can inhibit the welfare state of the lambs (Sevi et al., 2001 and reduced animal welfare can have detrimental effects on meat quality in many animals species (Gregory, 1998 as well as in sheep (Napolitano et al., 2002a. A possible recover from conditions of poor animal welfare may be attained through the administration of gentle contacts by humans (Boivin et al., 2000 which may supply an additional social bond with members of a different animal species. The present study aims to verify the effect of artificial rearing on lamb welfare and meat quality, and assess the possibility to increase both by means of gentling.

    2017-10-01

    Full Text Available In applying communicative competence that became the utmost teaching method in teaching English program, the lecturers found the fact that the Islamic communication students are apparently reluctant to speak and communicate their ideas confidently. It happens because they thought that they do not know what they are going to say and how they are going to say their ideas. By knowing these problems the lecturers then tried to analyze the sequences of Islamic-content-TED and integrate those public speaking sequences from TED talks to STID Al-Hadid’s students to give an understanding and also to improve the confidence and quality in delivering public speaking speech for the sophomore students who are majoring Islamic Communication & Broadcasting. For further, in order to master this skill, students are also expected to find noble ideas to be shared in their personal public speaking. This action research study then found out that having sharing the sequences of TED talks, the student’s public speaking productions are more organized and powerful moreover; the fluency and also the student’s accuracy of the students could be controlled well.

  18. Ted Madden's Network Methods: Applications to the Earth's Schumann Resonances

    Science.gov (United States)

    Williams, E. R.; Yu, H.

    2014-12-01

    Ted Madden made clever use of electrical circuit concepts throughout his long career in geophysical research: induced polarization, DC resistivity, magnetotellurics, Schumann resonances, the transport properties of rocks and even elasticity and the brittle failure of stressed rocks. The general methods on network analogies were presented in a terse monograph (Madden, 1972) which came to be called "The Grey Peril" by his students, named more for the challenge of deciphering the material as for the color of its cover. This talk will focus on Ted's first major use of the transmission line analogy in treating the Earth's Schumann resonances. This approach in Madden and Thompson (1965) provided a greatly simplified two-dimensional treatment of an electromagnetic problem with a notable three-dimensional structure. This skillful treatment that included the role of the Earth's magnetic field also led to predictions that the Schumann resonance energy would leak into space, predictions that have been verified nearly 50 years later in satellite observations. An extension of the network analogy by Nelson (1967) using Green's function methods provides a means to treat the inverse problem for the background Schumann resonances for the global lightning activity. The development of Madden's methods will be discussed along with concrete results based on them for the monitoring of global lightning.

    2013-04-01

    Carbon dioxide is a greenhouse gas that is a major contributor to global warming. Developing methods that can effectively capture CO2 is the key to reduce its emission to the atmosphere. Recent research shows that microporous metal organic frameworks (MOFs) are emerging as a promising family of adsorbents that may be promising for use in adsorption based capture and separation of CO2 from power plant waste gases. In this work we report the synthesis, crystal structure analysis and pore characterization of two microporous MOF structures, [M2(hfipbb)2(ted)] (M=Zn (1), Co (2); H2hfipbb=4,4-(hexafluoroisopropylidene)-bis(benzoic acid); ted=triethylenediamine). The CO2 and N2 adsorption experiments and IAST calculations are carried out on [Zn2(hfipbb)2(ted)] under conditions that mimic post-combustion flue gas mixtures emitted from power plants. The results show that the framework interacts with CO2 strongly, giving rise to relatively high isosteric heats of adsorption (up to 28 kJ/mol), and high adsorption selectivity for CO2 over N2, making it promising for capturing and separating CO2 from CO2/N2 mixtures.

However, we find no studies develop a watershed erosion modeling framework based on sediment connectivity, and few, if any, studies have quantified sediment connectivity for gently rolling systems. We develop a new predictive sediment connectivity model that relies on the intersecting probabilities for sediment supply, detachment, transport, and buffers to sediment transport, which is integrated in a watershed erosion model framework. The model predicts sediment flux temporally and spatially across a watershed using field reconnaissance results, a high-resolution digital elevation models, a hydrologic model, and shear-based erosion formulae. Model results validate the capability of the model to predict erosion pathways causing sediment connectivity. More notably, disconnectivity dominates the gently rolling watershed across all morphologic levels of the uplands, including, microtopography from low energy undulating surfaces across the landscape, swales and gullies only active in the highest events, karst sinkholes that disconnect drainage areas, and floodplains that de-couple the hillslopes from the stream corridor. Results show that sediment connectivity is predicted for about 2% or more the watershed's area 37 days of the year, with the remaining days showing very little or no connectivity. Only 12.8 ± 0.7% of the gently rolling watershed shows sediment connectivity on the wettest day of the study year. Results also highlight the importance of urban/suburban sediment pathways in gently rolling watersheds, and dynamic and longitudinal distributions of sediment connectivity might be further investigated in future work. We suggest the method herein provides the modeler with an added tool to account for sediment transport criteria and has the potential to reduce computational costs in watershed erosion modeling.

    Thyroid eye disease (TED) is an autoimmune condition with an unpredictable course that may lead to permanent facial disfigurement. Eyelid retraction is one of the most common findings, and frequently demands attention due to ocular exposure and impaired cosmesis. Surgical treatment remains the most effective option, but there is a role for temporary corrections during the active phase of the disease, as well as in patients who are poor surgical candidates. The aim of this review is to describe the non-surgical modalities currently available for treatment of eyelid malposition in TED. The authors have focused on the use of hyaluronic acid, triamcinolone injections and botulinum toxin type A as non-surgical treatment alternatives, paying special attention to dosing, technique, efficacy and duration of effect. Non-surgical treatment modalities may represent viable in cases where surgical correction is not an option. Although temporary, these modalities appear to be beneficial for ocular exposure remediation, improving quality of life and broadening our therapeutic arsenal. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    The steady expansion in the capacity of modern beamlines for high-throughput data collection, enabled by increasing X-ray brightness, capacity of robotics and detector speeds, has pushed the bottleneck upstream towards sample preparation. Even in ligand-binding studies using crystal soaking, the experiment best able to exploit beamline capacity, a primary limitation is the need for gentle and nontrivial soaking regimens such as stepwise concentration increases, even for robust and well characterized crystals. Here, the use of acoustic droplet ejection for the soaking of protein crystals with small molecules is described, and it is shown that it is both gentle on crystals and allows very high throughput, with 1000 unique soaks easily performed in under 10 min. In addition to having very low compound consumption (tens of nanolitres per sample), the positional precision of acoustic droplet ejection enables the targeted placement of the compound/solvent away from crystals and towards drop edges, allowing gradual diffusion of solvent across the drop. This ensures both an improvement in the reproducibility of X-ray diffraction and increased solvent tolerance of the crystals, thus enabling higher effective compound-soaking concentrations. The technique is detailed here with examples from the protein target JMJD2D, a histone lysine demethylase with roles in cancer and the focus of active structure-based drug-design efforts.

    The formation of transient networks in response to external stimuli or as a reflection of internal cognitive processes is a hallmark of human brain function. However, its identification in fMRI data of the human brain is notoriously difficult. Here we propose a new method of fMRI data analysis that tackles this problem by considering large-scale, task-related synchronisation networks. Networks consist of nodes and edges connecting them, where nodes correspond to voxels in fMRI data, and the weight of an edge is determined via task-related changes in dynamic synchronisation between their respective times series. Based on these definitions, we developed a new data analysis algorithm that identifies edges that show differing levels of synchrony between two distinct task conditions and that occur in dense packs with similar characteristics. Hence, we call this approach "Task-related Edge Density" (TED). TED proved to be a very strong marker for dynamic network formation that easily lends itself to statistical analysis using large scale statistical inference. A major advantage of TED compared to other methods is that it does not depend on any specific hemodynamic response model, and it also does not require a presegmentation of the data for dimensionality reduction as it can handle large networks consisting of tens of thousands of voxels. We applied TED to fMRI data of a fingertapping and an emotion processing task provided by the Human Connectome Project. TED revealed network-based involvement of a large number of brain areas that evaded detection using traditional GLM-based analysis. We show that our proposed method provides an entirely new window into the immense complexity of human brain function.

    Tissue-specific overexpression of useful genes, which we can design according to their cause-and-effect relationships, often gives valuable gain-of-function phenotypes. To develop genetic tools in woody biomass engineering, we produced a collection of Arabidopsis lines that possess chimeric genes of a promoter of an early xylem differentiation stage-specific gene, Arabidopsis Tracheary Element Differentiation-related 4 (AtTED4) and late xylem development-associated genes, many of which are uncharacterized. The AtTED4 promoter directed the expected expression of transgenes in developing vascular tissues from young to mature stage. Of T2 lines examined, 42%, 49% and 9% were judged as lines with the nonrepeat type insertion, the simple repeat type insertion and the other repeat type insertion of transgenes. In 174 T3 lines, overexpression lines were confirmed for 37 genes, whereas only cosuppression lines were produced for eight genes. The AtTED4 promoter activity was high enough to overexpress a wide range of genes over wild-type expression levels, even though the wild-type expression is much higher than AtTED4 expression for several genes. As a typical example, we investigated phenotypes of pAtTED4::At5g60490 plants, in which both overexpression and cosuppression lines were included. Overexpression but not cosuppression lines showed accelerated xylem development, suggesting the positive role of At5g60490 in xylem development. Taken together, this study provides valuable results about behaviours of various genes expressed under an early xylem-specific promoter and about usefulness of their lines as genetic tools in woody biomass engineering. © 2017 The Authors.

    TED is a severe eye disease leading in rare cases to decrease of sight, optic nerve compression and blindness. Recently, significant progresses in understanding the disease have been done. Nevertheless, the treatment of the disease, especially in its severe form remains challenging. Glucocorticoids (GC) have been the basis of the treatment for a long time. Orbital irradiation (OI) and optical decompression (OD) are also used in managing the severe forms of TED. Somatostatin, intravenous immunoglobulin have been also used, with conflicting results. Regarding the potential for the treatment of TED with cytokine antagonists, controlled clinical studies are not available. Since cytokines play an important role in the pathogenesis of the TED, they seemed to be logical choice for modern TED treatment. It has been shown that both Th1 (interleukin-2, tumor necrosis factor γ, interleukin γ) and Th2 (interleukin-4,-5-,-10) profile T cells are activated in the TED. We therefore measured interleukin-γ, IF-γ and interleukin -10 (IL-10)(Th1 and Th2 pattern) to assess its relationship to the course of the disease. This paper shows that both Th1 (Il-2) and Th2 (If-γ) pathways represented by those two cytokines are not involved (Il-10 before 2,29±5,23 and after treatment 3,77±8,44; IF γ before 0,50±0,24 and after treatment 0,35±0,19). No relationship to the response to treatment was found. GC resulted in positive response in 8/22 patients, OI (12 patients) given after CS therapy, resulted in a response in all patients. Increase in proptosis, loss of visual acuity is spite of CS treatment prompted OD in two patients, who both recovered visual acuity and proptosis fell under 25mm Hertel. PMID:18039196

    2018-03-01

    Debriding and disinfecting complex anatomies within the root canal system pose a major challenge during root canal therapy. Even with current chemomechanical techniques, debris and bacterial remnants are commonly left behind, which are generally believed to increase the risk of endodontic failure. This case details the use of a new technique to debride complex apical anatomy in a maxillary molar. A 48-year-old female presented to the clinic with a chief complaint of increasing pain in her tooth. Clinical examination of the right first maxillary molar (#3) revealed moderate sensitivity to percussion and mild sensitivity to palpation. A pulpal diagnosis of symptomatic irreversible pulpitis and a periapi-cal diagnosis of symptomatic apical periodontitis were made. Mechanical instrumentation was performed using rotary file size #25/.04 for the mesiobuccal and distobuccal canals and size #25/.06 for the palatal canal to create a fluid path and enable obturation of the root canal system following the GentleWave® Procedure. The GentleWave Procedure was completed using Multisonic Ultracleaning™ for complete debridement and disinfection of the root canal system. The tooth was obturated using a warm vertical continuous wave obturation technique. Postoperative radiographs revealed complex anatomy within the apical third that was undetected both during pre-operative radiography and mechanical instrumentation. The palatal canal exhibited a complex apical delta with multiple points of exit, and the mesiobuccal canal revealed an undetected lateral canal within the apical third that had a separate and distinct egress. Conclusion and clinical significance: It is important for the clinician to debride and disinfect complex anatomy within the root canal system to reduce the risk of endodontic failure. This case report highlights the clinical significance of utilizing the GentleWave Procedure for detecting complex apical anatomy during endodontic therapy.

    Environmental factors play a significant role in well-being of laboratory animals. Regulations and guidelines recommend, if not require, that stressors such as bright lighting, smells, and noises are eliminated or reduced to maximize animal well-being. A factor that is often overlooked is handling and how researchers interact with their animals. Researchers, lab assistants, and husbandry staff in animal facilities may use inconsistent handling methods when interacting with rodents, but humans should be considered a part of the animal's social environment. This study examined the effects of different handling techniques on depressive-like behavior, measured by the Porsolt forced swim test, in adult C57BL/6J male mice. The same two researchers handled the mice in a gentle, aggressive, or minimal (control) fashion over approximately two weeks prior to testing. The results demonstrated a beneficial effect of gentle handling: gentle handling reduced swimming immobility in the forced swim test compared to mice that were aggressively or minimally handled. We argue that gentle handling, rather than methodical handling, can foster a better relationship between the handlers and rodents. Although handling is not standardized across labs, consistent gentle handling allows for less challenging behavioral testing, better data collection, and overall improved animal welfare.

    The Traumatic Brain Injury Endpoints Development (TED) Initiative is a 5-year, Department of Defense (DoD) funded project that is working toward the ultimate goal of developing better designed clinical trials, leading to more precise diagnosis, and effective treatments for traumatic brain injury (TBI). TED is comprised of leading academic clinician-scientists, along with innovative industry leaders in biotechnology and imaging technology, patient advocacy organizations, and philanthropists, working collaboratively with regulatory authorities, specifically the US Food and Drug Administration (FDA). The goals of the TED Initiative are to gain consensus and validation of TBI clinical outcome assessment measures and biomarkers for endorsement by global regulatory agencies for use in drug and device development processes. This manuscript summarizes the Initiative's Stage 1 progress over the first 18 months, including intensive engagement with a number of FDA divisions responsible for review and validation of biomarkers and clinical outcome assessments, progression into the prequalification phase of FDA's Medical Device Development Tool program for a candidate set of neuroimaging biomarkers, and receipt of FDA's Recognition of Research Importance Letter regarding TBI. Other signal achievements relate to the creation of the TED Metadataset, harmonizing study measures across eight major TBI studies, and the leadership role played by TED investigators in the conversion of the NINDS TBI Common Data Elements (CDEs) to Clinical Data Interchange Standards Consortium (CDISC) standards. This paper frames both the near-term expectations and the Initiative's long-term vision to accelerate approval of treatments for patients affected by TBI in urgent need of effective therapies.

    Sudden Cardiac Death--SCD --is a major unmet health problem that needs urgent and prompt solution. AICDs are very expensive, risky and indicated for a small group of patients, at the highest risk. AEDs--Automatic External Defibrillators--are designed for public places and although safe, cannot enter the home-market due to their cost and need for constant, high-cost maintenance. We developed TED, a low-cost AED that derives its energy off the mains, designed for home-use, to save SCD victims' lives. Copyright © 2014 Elsevier Inc. All rights reserved.

    To identify components of a provisional clinical response index for thyroid eye disease (CRI-TED) using a modified Delphi technique. The International Thyroid Eye Disease Society (ITEDS) conducted a structured, 3-round Delphi exercise establishing consensus for a core set of measures for clinical trials in TED. The steering committee discussed the results in a face-to-face meeting (nominal group technique) and evaluated each criterion with respect to its feasibility, reliability, redundancy, and validity. Redundant measures were consolidated or excluded. Criteria were parsed into 11 domains for the Delphi surveys. Eighty four respondents participated in the Delphi-1 survey, providing 220 unique items. Ninety- two members (100% of the respondents from Delphi 1 plus eight new participants) responded in Delphi-2 and rated the same 220 items. Sixty-four members (76% of participants) rated 153 criteria in Delphi-3 (67 criteria were excluded due to redundancy). Criteria with a mean greater than 6 (1 least appropriate to 9 most appropriate) were further evaluated by the nominal group technique and provisional core measures were chosen. Using a Delphi exercise, we developed provisional core measures for assessing disease activity and severity in clinical trials of therapies for TED. These measures will be iteratively refined for use in multicenter clinical trials. PMID:19752424

    In the past several decades, advances in imaging and interventional techniques have been accompanied by an increase in medical radiation dose to the public. Radiation exposure is even more important in children, who are more sensitive to radiation and have a longer lifespan during which effects may manifest. To address radiation safety in pediatric computed tomography, in 2008 the Alliance for Radiation Safety in Pediatric Imaging launched an international social marketing campaign entitled Image Gently. This article describes the next phase of the Image Gently campaign, entitled Step Lightly, which focuses on radiation safety in pediatric interventional radiology.

    Although case studies can be a helpful didactic aid when teaching personality assessment and illustrating use of a test, they can, of course, not be used as "evidence" that a test "works" or does not work. This article, however, reviews and discusses the far more problematic uses instantiated in a case study of Ted Kaczynski's Minnesota Multiphasic Personality Inventory (MMPI). A series of errors of omission and commission are identified in Butcher, Hass, Greene, and Nelson's ( 2015 ) effort to criticize the MMPI-2-RF. These include not disclosing that Butcher's interpretive Minnesota Report for Forensic Settings indicates that the protocol is invalid, not including most of the MMPI-2 and MMPI-2-RF scores that contradict the authors' assertions, and mischaracterizing the MMPI-2-RF findings. Proper use of a case study is then illustrated by a discussion of diagnostic considerations indicated by the MMPI-2-RF findings.

    Serum proinflamatory cytokines were found to be altered in Graves disease (GD) and in TED. Serum values of IL1alpha, IL-1beta, IL-6, TNF-alpha were assessed in 22 patients with TED before and after treatment (aged 46.82 +/- 12.47, M:F=16:6). Free thyroxin was high, TSH low, thyroid ultrasound showed diffuse thyroid enlargement, treatment with antithyroid drugs propylthyouracil (PTU) or methymasol (MMI) resulted in clinical and hormonal remission. Several months after the initiation of the signs of hyperthyroidism, a progression in the ophthalmopathy was observed (Hertel up to 25 mm: normal 15-17 mm) while patients were clinically and hormonally euthyroid. Blood was collected in euthyroid state (with TED signs present, before corticosteroid therapy (CS) treatment) and after 3 months of treatment (patients without TED and without TED treatment). CS resulted in response of 8/22 patients. Ophthalmic irradiation (01) given with CS therapy, resulted in a response in twelve patients (12/12). Lack of response to CS treatment, with rapid increase in proptosis, and loss of visual acuity prompted ophthalmic decompression (OD) in two patients. Both recovered visual acuity, while proptosis fell under 25 mm Hertel. The control group had 29 persons (aged 51.86 +/-10.52, M:F = 16:13). A significant difference was found in the serum levels of IL-1alpha between the groups of controls (0.74+/-0.55 pg/ml) and patients before treatment (1.85 +/- 1.85 pg/ml; p TED treatment its concentration raised to 2.07 +/- 1.82 pg/ml (higher than the pretreatment; NS). For patients with low Clinical Activity Score (CAS) scores (1-5) there was no change in IL-6 concentrations before (1.03+/-o.64 pg/ml) and after treatment (1.07 +/- 0.63 pg/ml). Patients with higher CAS scores (6-10) had a change in IL-6 levels (from 1.32+/-1.00 to 2.67 +/- 4.84; p > 0.05). In addition, patients with pathological VEP had no changes in IL-6 (from 0.93 +/- 0.53 to 0.97 +/- 0.32 pg/ml), while patients with normal VEP had

    Infrared Search and Track (IRST) and threat warning systems are used in vehicle mounted or in fixed land positions. Migration of this technology to the man portable applications proves to be difficult due to the tight constraints of power consumption, dimensions, weight and due to the high video rate requirements. In this report we provide design details of a novel transient event detection (TED) system, capable of detection of blasts and gun shot events in a very wide field of view, while used by an operator in motion

    2015-07-01

    In the event of cardiac arrest, cardiopulmonary resuscitation (CPR) is a well-established technique to maintain oxygenation of tissues and organs until medical equipment and staff are available. During CPR, chest compressions help circulate blood and have been shown in animal models to be a means of short-term oxygenation. In this study, we tested whether gentle chest pressure can generate meaningful tidal volume in paediatric subjects. This prospective cohort pilot study recruited children under the age of 17 years and undergoing any surgery requiring general anaesthetic and endotracheal intubation. After induction of general anaesthesia, tidal volumes were obtained before and after intubation by applying a downward force on the chest which was not greater than the patient's weight. Mean tidal volumes were compared for unprotected versus protected airway and for type of surgery. Mean tidal volume generated with an unprotected and protected airway was 2.7 (1.7) and 2.9 (2.3) mL/kg, respectively. Mean tidal volume generated with mechanical ventilation was 13.6 (4.9) mL/kg. No statistical significance was found when comparing tidal volumes generated with an unprotected or protected airway (p = 0.20), type of surgery (tonsillectomy and/or adenoidectomy versus other surgery) (unprotected, p = 0.09; protected, p = 0.37), and when age difference between groups was taken into account (p = 0.34). Using gentle chest pressure, we were able to generate over 20% of the tidal volume achieved with mechanical ventilation. Our results suggest that gentle chest pressure may be a means to support temporary airflow in children. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    2004-01-01

    We present simulations of B TED based on a complete calculation of the extended defect growth/shrinkage during annealing. The Si self-interstitial supersaturation calculated at the extended defect depth is coupled to the set of equations for the B kick-out diffusion through a generation/recombination term in the diffusion equation of the Si self-interstitials. The simulations are compared to the measurements performed on a Si wafer containing several B marker layers, where the amount of TED varies from one peak to the other. The good agreement obtained on this experiment is very promising for the application of these calculations to the case of ultra-shallow B + implants

    The EURATOM GENTLE project is a pan-European effort pulling together the leading institutions in the field of nuclear engineering and education to create a sustainable life-long learning programme in the field of nuclear fission technology. Directly targeting the needs of industry, research, regulatory and TSO organizations, three different learning programmes have been developed: 1) support for student research experiences (where graduate and undergraduate students can apply for internships at GENTLE partners), 2) inter-semester courses for undergraduate and graduate students on topics outside regular curricula (organized at partner institutes) and 3) a professional education programme (targeting professionals with at least 5 years of working experience, not necessarily in the nuclear field) that are intending to work in the nuclear industry. The professional education programme has the goal to enhance participants' knowledge in the following fields: 1) Understanding nuclear power; 2) Producing energy with nuclear reactors; 3) Nuclear fuel: from ore to waste; 4) Conditions for societal justification of nuclear energy; and 5) Management systems. These learning programmes will be available for the public in 2015-2016. More information can be found at www.gentleproject.eu/

    2015-01-01

    Magnetic force combined with magnetic nanoparticles recently has shown potential for enhancing nucleic acid delivery. Achieving effective siRNA delivery into primary cultured cells is challenging. We compared the utility of magnetofection with lipofection procedures for siRNA delivery to primary and immortalized mammalian fibroblasts. Transfection efficiency and cell viability were analyzed by flow cytometry and effects of gene knockdown were quantified by real-time PCR. Lipofectamine 2000 and magnetofection achieved high transfection efficiencies comparable to similar gene silencing effects of about 80%; the cytotoxic effect of magnetofection, however, was significantly less. Magnetofection is a reliable and gentle alternative method with low cytotoxicity for siRNA delivery into difficult to transfect cells such as mammalian fibroblasts. These features are especially advantageous for functional end point analyses of gene silencing, e.g., on the metabolite level. PMID:20297946

    We describe an innovative computer-based method for the analysis of gas flow using a modified airway management technique to perform percutaneous dilatational tracheotomy (PDT) with a rigid tracheotomy endoscope (TED). A test lung was connected via an artificial trachea with the tracheotomy endoscope and ventilated using superimposed high-frequency jet ventilation. Red packed cells were instilled during the puncture phase of a simulated percutaneous tracheotomy in a trachea model and migration of the red packed cells during breathing was continuously measured. Simultaneously, the calculation of the gas-flow within the endoscope was numerically simulated. In the experimental study, no backflow of blood occurred during the use of superimposed high-frequency jet ventilation (SHFJV) from the trachea into the endoscope nor did any transportation of blood into the lower respiratory tract occur. In parallel, the numerical simulations of the openings of TED show almost positive volume flows. Under the conditions investigated there is no risk of blood aspiration during PDT using the TED and simultaneous ventilation with SHFJV. In addition, no risk of impairment of endoscopic visibility exists through a backflow of blood into the TED. The method of numerical simulation offers excellent insight into the fluid flow even under highly transient conditions like jet ventilation.

    Full Text Available Previous studies on healing by gentle touch in clients with various illnesses indicated substantial improvements in psychological well-being, suggesting that this form of treatment might be helpful for people with impaired quality of mental health. The purpose of this study was to evaluate the effectiveness and safety of healing by gentle touch in subjects with self-reported impairments in their psychological well-being or mental health. One hundred and forty-seven clients who identified themselves as having psychological problems received four treatment sessions. Pre- to post-treatment changes in psychological and physical functioning were assessed by self-completed questionnaires which included visual analogue scales (VAS and the EuroQoL (EQ-5D. Participants recorded reductions in stress, anxiety and depression scores and increases in relaxation and ability to cope scores (all P < 0.0004. Improvements were greatest in those with the most severe symptoms initially. This open study provides strong circumstantial evidence that healing by gentle touch is safe and effective in improving psychological well-being in participants with self-reported psychological problems, and also that it safely complements standard medical treatment. Controlled trials are warranted.

    PurposeTo compare clinical and urodynamic results of transurethral resection of the prostate (TURP) to original and PErFecTED prostate artery embolization (PAE) methods for benign prostatic hyperplasia.MethodsWe prospectively randomized 30 patients to receive TURP or original PAE (oPAE) and compared them to a cohort of patients treated by PErFecTED PAE, with a minimum of 1-year follow-up. Patients were assessed for urodynamic parameters, prostate volume, international prostate symptom score (IPSS), and quality of life (QoL).ResultsAll groups were comparable for all pre-treatment parameters except bladder contractility and peak urine flow rate (Q{sub max}), both of which were significantly better in the TURP group, and IIEF score, which was significantly higher among PErFecTED PAE patients than TURP patients. All groups experienced significant improvement in IPSS, QoL, prostate volume, and Q{sub max}. TURP and PErFecTED PAE both resulted in significantly lower IPSS than oPAE but were not significantly different from one another. TURP resulted in significantly higher Q{sub max} and significantly smaller prostate volume than either original or PErFecTED PAE but required spinal anesthesia and hospitalization. Two patients in the oPAE group with hypocontractile bladders experienced recurrence of symptoms and were treated with TURP. In the TURP group, urinary incontinence occurred in 4/15 patients (26.7 %), rupture of the prostatic capsule in 1/15 (6.7 %), retrograde ejaculation in all patients (100 %), and one patient was readmitted for temporary bladder irrigation due to hematuria.ConclusionsTURP and PAE are both safe and effective treatments. TURP and PErFecTED PAE yield similar symptom improvement, but TURP is associated with both better urodynamic results and more adverse events.

  1. A high-quality factor of 267 000 micromechanical silicon resonator utilizing TED-free torsional vibration mode

    2012-12-01

    In industrial applications of a micromechanical silicon resonator as a physical sensor, a high-quality factor Q and a low-temperature coefficient of Q (TCQ) are required for high sensitivity in a wide temperature range. Although the newly developed thin film encapsulation technique enables a beam to operate with low viscous damping in a vacuum cavity, the Q of a flexural vibration mode is limited by thermo-elastic damping (TED). We proposed a torsional beam resonator which features both a high Q and a low TCQ because theoretically the torsional vibration mode does not suffer from TED. From experiments, Q of 267 000 and TCQ of 1.4 for the 20 MHz torsional vibration mode were observed which were superior to those of the flexural mode. The pressure of the residual gas in the cavity of only 20 pl volume, which is one of the energy loss factors limiting the Q, was successfully estimated to be 1-14 Pa. Finally, the possibilities of improving the Q and the difference of the measured TCQ from a theoretical value were discussed.

    A survey was conducted to assess the impact of a TED-like educational session on participants' willingness to accept dental implant therapy. Volunteers interested in having information about dental implant therapies were recruited and asked to complete a two-part survey before and after an educational session. The initial survey elicited demographic information, self-perceived knowledge on dental implants and willingness to this kind of treatment. A "TED-style" presentation that provided information about dental implant treatments was conducted before asking the participants to complete a second set of questions assessing the impact of the session. The survey was completed by 104 individuals, 78.8% were women and the mean age was 66.5±10.8. Before the educational session, 76.0% of the participants refused dental implants mainly due to lack of knowledge. After the educational session, the rejection of dental implants decreased by almost four folds to 20.2%. This study proved that an educational intervention can significantly increase willingness to accept treatment with dental implants in a segment of the population who is interested in having information about dental implant therapy. Furthermore, educational interventions, such as TED-like talks, might be useful to increase popular awareness on dental implant therapy.

    2016-01-01

    Cap-independent translational enhancers (CITEs) have been identified at the 3´-terminal regions of distinct plant positive-strand RNA viruses belonging to families Tombusviridae and Luteoviridae. On the bases of their structural and/or functional requirements, at least six classes of CITEs have been defined whose distribution does not correlate with taxonomy. The so-called TED class has been relatively under-studied and its functionality only confirmed in the case of Satellite tobacco necrosis virus, a parasitic subviral agent. The 3´-untranslated region of the monopartite genome of Pelargonium line pattern virus (PLPV), the recommended type member of a tentative new genus (Pelarspovirus) in the family Tombusviridae, was predicted to contain a TED-like CITE. Similar CITEs can be anticipated in some other related viruses though none has been experimentally verified. Here, in the first place, we have performed a reassessment of the structure of the putative PLPV-TED through in silico predictions and in vitro SHAPE analysis with the full-length PLPV genome, which has indicated that the presumed TED element is larger than previously proposed. The extended conformation of the TED is strongly supported by the pattern of natural sequence variation, thus providing comparative structural evidence in support of the structural data obtained by in silico and in vitro approaches. Next, we have obtained experimental evidence demonstrating the in vivo activity of the PLPV-TED in the genomic (g) RNA, and also in the subgenomic (sg) RNA that the virus produces to express 3´-proximal genes. Besides other structural features, the results have highlighted the key role of long-distance kissing-loop interactions between the 3´-CITE and 5´-proximal hairpins for gRNA and sgRNA translation. Bioassays of CITE mutants have confirmed the importance of the identified 5´-3´ RNA communication for viral infectivity and, moreover, have underlined the strong evolutionary constraints that may

  8. Unlocking higher harmonics in atomic force microscopy with gentle interactions.

    2014-01-01

    In dynamic atomic force microscopy, nanoscale properties are encoded in the higher harmonics. Nevertheless, when gentle interactions and minimal invasiveness are required, these harmonics are typically undetectable. Here, we propose to externally drive an arbitrary number of exact higher harmonics above the noise level. In this way, multiple contrast channels that are sensitive to compositional variations are made accessible. Numerical integration of the equation of motion shows that the external introduction of exact harmonic frequencies does not compromise the fundamental frequency. Thermal fluctuations are also considered within the detection bandwidth of interest and discussed in terms of higher-harmonic phase contrast in the presence and absence of an external excitation of higher harmonics. Higher harmonic phase shifts further provide the means to directly decouple the true topography from that induced by compositional heterogeneity.

Restricting attention to the first decade of his career, the 1950s, he discovered from work on the Torridonian (1951-1953) that fine-grained red sandstones were generally suitable for paleomagnetic work (1951-1952). He rediscovered (1951) that paleomagnetism could be used to test continental drift, and initiated (1951) the first paleomagnetic test of whether India had drifted northward relative to Asia and argued (1954) that it had. He also made significant contributions to the first APW path for Great Britain (Creer, Irving, and Runcorn, 1954). He was the first to draw two APW paths to explain results from Great Britain and North America (1956) and to use paleomagnetism and paleoclimatology together to argue for continental drift (1954, 1956). With Ron Green, his first student, he first APW path for Australia (1958). He was the first to invoke axial rotations to explain away an apparent anomaly with an APW path (1959). His work on the Torridonian led to the first description of stratigraphically sequential reversals in sedimentary rocks. Moreover, his 1959 superb review of the paleomagnetic support for continental drift was instrumental in Hess's becoming a continental drifter before he came up with the idea of seafloor spreading.

    Drop-on-demand (DOD) principle appears to be a particular promising approach for manufacturing personalized treatments carefully tailored to a patient's genetic background. The authors have recently developed a DOD method for gentle printing of personalized medicines. A fluid is infused into an electrically insulating nozzle to form a pendant drop. A sufficiently strong voltage pulse is applied to external electrodes to stretch the pendant drop until it touches an electrically insulating film and forms a liquid bridge. As the liquid bridge is intentionally formed in an unstable configuration, it breaks up, creating two drops, one on the film and the other hanging from the nozzle. To prove the validity and versatility of the method, experiments are conducted on fluids whose viscosity, conductivity, dielectric constant, and surface tension vary over a broad range, respectively: 1-1045 cP, 0.02-290 μS/cm, 9-78, and 41-72 dyn/cm. We present a scaling analysis that captures the essential physics of drop evolution and provides the critical design guidelines. The work was supported by NSF Engineering Research Center on Structured Organic Particulate Systems.

  13. i-TED: A novel concept for high-sensitivity (n,γ) cross-section measurements

    Domingo-Pardo, C.

    2016-07-01

    A new method for measuring (n , γ) cross-sections aiming at enhanced signal-to-background ratio is presented. This new approach is based on the combination of the pulse-height weighting technique with a total energy detection system that features γ-ray imaging capability (i-TED). The latter allows one to exploit Compton imaging techniques to discriminate between true capture γ-rays arising from the sample under study and background γ-rays coming from contaminant neutron (prompt or delayed) captures in the surrounding environment. A general proof-of-concept detection system for this application is presented in this paper together with a description of the imaging method and a conceptual demonstration based on Monte Carlo simulations.

    Fundal pressure (pushing on the upper part of the uterus in the direction of the birth canal) is often performed in routine practice, however the benefit and indications for its use are unclear and vigorous pressure is potentially harmful. There is some evidence that it may be applied routinely or to expedite delivery in some situations (e.g. fetal distress or maternal exhaustion), particularly in settings where other methods of achieving delivery (forceps, vacuum) are not available. Gentle assisted pushing (GAP) is an innovative method of applying gentle but steady pressure to the uterine fundus with the woman in an upright posture. This trial aims to evaluate the use of GAP in an upright posture, or upright posture alone, on reducing the mean time of delivery and the associated maternal and neonatal complications in women not having delivered following 15-30 min in the second stage of labour. We will conduct a multicentre, randomized, unblinded, controlled trial with three parallel arms (1:1:1). 1,145 women will be randomized at three hospitals in South Africa. Women will be eligible for inclusion if they are ≥18 years old, nulliparous, gestational age ≥ 35 weeks, have a singleton pregnancy in cephalic presentation and vaginal delivery anticipated. Women with chronic medical conditions or obstetric complications are not eligible. If eligible women are undelivered following 15-30 min in the second stage of labour, they will be randomly assigned to: 1) GAP in the upright posture, 2) upright posture only and 3) routine practice (recumbent/supine posture). The primary outcome is the mean time from randomization to complete delivery. Secondary outcomes include operative delivery, adverse neonatal outcomes, maternal adverse events and discomfort. This trial will establish whether upright posture and/or a controlled method of applying fundal pressure (GAP) can improve labour outcomes for women and their babies. If fundal pressure is found to have a measurable

    Zn(bdc)(ted)0.5 is metal-organic framework crystallized in a tetragonal space group with a 3D porous structure containing intersecting channels of two different sizes. The larger channels are parallel to the c axis and have a cross section 7.5 × 7.5 AA. The smaller channels are along both the a- and b-axes and have a cross section of 4.8 × 3.2 AA. We measured methane adsorption isotherms at several different temperatures between 82 and 102 K. We calculated the effective specific surface area, isosteric heat and binding energy values. Two distinct substeps were observed in the isotherms corresponding to two different adsorption sites. The origin of the substeps will be discussed.

    Large exposure of skin area of an image is considered obscene. This only fact may lead to many false images having skin-like objects and may not detect those images which have partially exposed skin area but have exposed erotogenic human body parts. This paper presents a novel method for detecting nipples from pornographic image contents. Nipple is considered as an erotogenic organ to identify pornographic contents from images. In this research Gentle Adaboost (GAB) haar-cascade classifier and haar-like features used for ensuring detection accuracy. Skin filter prior to detection made the system more robust. The experiment showed that, considering accuracy, haar-cascade classifier performs well, but in order to satisfy detection time, train-cascade classifier is suitable. To validate the results, we used 1198 positive samples containing nipple objects and 1995 negative images. The detection rates for haar-cascade and train-cascade classifiers are 0.9875 and 0.8429, respectively. The detection time for haar-cascade is 0.162 seconds and is 0.127 seconds for train-cascade classifier.

    Oxfam's Gender and Development Unit (GADU) began in 1985 without scheduled time (all personnel had full-time jobs), premises (whatever space was vacant at the time), or money. David Bryer, incoming overseas director, supported the group and gave it an office and a half-time post. GADU's goal was to raise awareness about gender issues within Oxfam, and to formulate policy for the Overseas Division. What was promoted overseas was to be promoted within Oxfam. GADU cooperated with the Oxfam Women's Group, the Equal Opportunities Working Group, and the Creche Committee (which got the workplace nursery started). Members of GADU steering group included persons from education, campaigns, and all area desks. Members would bring gender issues to the attention of their departments, and GADU would meet regularly to discuss strategies and problems. Colleagues remained surprisingly resistant to ideas current in the development world and suspicious of GADU. Although gender is now on Oxfam's agenda, the struggle continues. Perhaps GADU was born too gently; perhaps "the cotton-wool of Oxfam liberalism" should have been ripped off, and "armed struggle" begun.

    In this paper the counts and colors of the faint galaxies observed in the Hubble Deep Field are fitted by means of simple luminosity evolution models that incorporate a numerous population of fading dwarfs. The observed color distribution of the very faint galaxies now allows us to put constraints on the star formation history in dwarfs. It is shown that the star-forming activity in these small systems has to proceed in a gentle way, i.e., through episodes where each one lasts much longer tha...

  2. Shoaling internal solitary waves of depression over gentle slopes

    Rivera, Gustavo; Diamessis, Peter

    2017-11-01

    The shoaling of an internal solitary wave (ISW) of depression over gentle slopes is explored through fully nonlinear and non-hydrostatic simulations using a high resolution/accuracy deformed spectral multidomain penalty method. During shoaling, the wave does not disintegrate as in the case of steeper slope but, instead, maintains its symmetric shape. At the core of the wave, an unstable region forms, characterized by the entrapment of heavier-over-light fluid. The formation of this convective instability is attributed to the vertical stretching by the ISW of the near-surface vorticity layer associated with the baroclinic background current. According to recent field observations in the South China Sea, the unstable region drives localized turbulent mixing within the wave, estimated to be up to four times larger than that in the open ocean, in the form of a recirculating trapped core. In this talk, emphasis is placed on the structure of the unstable region and the persistence of a possible recirculating core using simulations which capture 2D wave propagation combined with 3D representation of the transition to turbulence. As such, a preliminary understanding of the underlying fluid mechanics and the potential broader oceanic significance of ISWs with trapped cores is offered.

    Edward (Ted) Irving (1927-2014) was one of the principal developers of paleomagnetism and an early champion of continental drift. Through careful multidisciplinary research and with great insight, he pioneered many aspects of paleomagnetism which continue to be actively researched. Irving was convinced of the reality of continental drift by 1954 and provided compelling arguments for its support in his classic 1964 textbook, but thought it would take the rest of his career to convince the rest of the scientific community. With the acceptance of plate tectonics in the late 1960s, he then applied his paleomagnetic tools to study young rocks (mid-ocean ridges), old rocks (the Laurentian shield), and mobile belts (the Appalachians and the Cordillera). In this poster we highlight recent work on several of his methods, results and ideas. Topics will include spherical statistics and paleosecular variation, the geomagnetic polarity time scale and the Kiaman superchron, paleoclimatic tests of paleogeography, compilation of paleomagnetic poles and the definition of apparent polar wander paths, and the paleogeography of cratons (e.g., Pangea) and mobile belts (e.g., Baja BC).

  4. The Reduction of TED in Ion Implanted Silicon

    2008-01-01

    The leading challenge in the continued scaling of junctions made by ion implantation and annealing is the control of the undesired transient enhanced diffusion (TED) effect. Spike annealing has been used as a means to reduce this effect and has proven successful in previous nodes. The peak temperature in this process is typically 1050 deg. C and the time spent within 50 deg. C of the peak is of the order of 1.5 seconds. As technology advances along the future scaling roadmap, further reduction or elimination of the enhanced diffusion effect is necessary. We have shown that raising the peak temperature to 1175 deg. C or more and reduction of the anneal time at peak temperature to less than a millisecond is effective in eliminating enhanced diffusion. We show that it is possible to employ a sequence of millisecond anneal followed by spike anneal to obtain profiles that do not exhibit gradient degradation at the junction and have junction depth and sheet resistance appropriate to the needs of future technology nodes. We have implemented millisecond annealing using a carbon dioxide laser to support high-volume manufacturing of 65 nm microprocessors and system-on-chip products. We further show how the use of molecular ion implantation to produce amorphousness followed by laser annealing to produce solid phase epitaxial regrowth results in junctions that meet the shallow depth and abruptness requirements of the 32 nm node.

  6. The White goddess, Ariadne and myth of the poetic self: The role of myth in forming creative-destructive relation Ted Hughes - Sylvia Plath

    2012-01-01

    Full Text Available Ted Hughes and Sylvia Plath were husband and wife; they were also two of the most remarkable poets of the twentieth century. Both Hughes and Plath were fond of mythic language - their attempts to find meaning in painful events of life took the form of a journey through myth. Just as Song contains a founding image in the work of Ted Hughes, Ariadne can be identified as a founding image in the work of Sylvia Plath. Both of these poems employ mythic language to identify the emotional pattern of each poet's creative stance toward the distinctive subject matter his or her art will seize on. Since Plath was, indeed, the form taken by the White Goddess in Hughes's life, it had been her destiny to inflict devastation on Hughes, as well as release his creative energy. These were the two aspects of her gift, as Robert Graves defined it: creativity and destruction. This paper is concerned with presenting an up-close look at a couple who saw each other as the means to becoming who they wanted to be: writers and mythic figures representing their generation.

    CMOS image sensors (CISs) with global shutter (GS) function are strongly required in order to avoid image degradation. However, CISs with GS function have generally been inferior to the rolling shutter (RS) CIS in performance, because they have more components. This problem is remarkable in small pixel pitch. The newly developed 3.4 µm pitch GS CIS solves this problem by using multiple accumulation shutter technology and the gentle slope light guide structure. As a result, the developed GS pixel achieves 1.8 e - temporal noise and 16,200 e - full well capacity with charge domain memory in 120 fps operation. The sensitivity and parasitic light sensitivity are 28,000 e - /lx·s and -89 dB, respectively. Moreover, the incident light angle dependence of sensitivity and parasitic light sensitivity are improved by the gentle slope light guide structure.

    The influence of reconstituting a murine monoclonal IgG 1 antibody kit with pertechnetate Tc99m on antibody distribution in the liver, spleen and sternal bone marrow of patients was examined. The 99m Tc-labelled antibody used is directed against non-specific cross-reacting antigen (NCA-95) and carcinoembryonic antigen (CEA) and has been successfully applied for imaging tissue inflammation and bone marrow scanning. Radioactivity uptake was determined in the liver, spleen, bone marrow and a precordial background region in a consecutive series of 25 patients, examined with an antibody preparation, routinely radiolabelled according to the manufacturer's recommendations and in 14 patients, in whom the antibody was reconstituted with special care, avoiding bubble formation and dropping of buffer into the antibody-containing vial. Gentle compared with routine antibody reconstitution caused a highly significant reduction of the antibody uptake in the liver, as determined by count densities, normalized to injected dose and acquisition time (13.2±5.5 vs 20.1±6.0 cpm per pixel, anti x±SD, P=0.008). The liver to background ratio was reduced from 3.4±1.4 to 1.9±0.5 (P<0.001). Spleen, sternal bone marrow and precordial background count rates were not significantly affected. These results clearly demonstrate that gentle antibody reconstitution can decrease non-specific antibody uptake in the liver by 34%±6.4% (anti x±SEM). Thus, scan quality is improved, and the potential deleterious camouflage of underlying structures is avoided. (orig.)

    Using the discrete element method, the authors have carried out 3D implementation of the problem on strength loss in surrounding rock mass in the vicinity of a production heading and on abutment pressure in a gently dripping coal seam. The calculation of forces at the contacts between particles accounts for friction, rolling resistance and viscosity. Between discrete particles modeling coal seam, surrounding rock mass and broken rocks, an elastic connecting element is introduced to allow simulating coherent materials. The paper presents the kinematic patterns of rock mass deformation, stresses in particles and the graph of the abutment pressure behavior in the coal seam.

  16. Deceleration-driven wetting transition of "gently" deposited drops on textured hydrophobic surfaces

    2010-11-01

    Many applications of rough superhydrophobic surfaces rely on the presence of droplets in a Cassie state on the substrates. A well established understanding is that if sessile droplets are smaller than a critical size, then the large Laplace pressure induces wetting transition from a Cassie to a Wenzel state, i.e., the liquid impales the roughness grooves. Thus, larger droplets are expected to remain in the Cassie state. In this work we report a surprising wetting transition where even a "gentle" deposition of droplets on rough substrates lead to the transition of larger droplets to the Wenzel state. A hitherto unknown mechanism based on rapid deceleration is identified. It is found that modest amount of energy, during the deposition process, is channeled through rapid deceleration into high water hammer pressure which induces wetting transition. A new "phase" diagram is reported which shows that both large and small droplets can transition to Wenzel states due to the deceleration and Laplace mechanisms, respectively. This novel insight reveals for the first time that the attainment of a Cassie state is more restrictive than previous criteria based on the Laplace pressure transition mechanism.

    2014-01-01

    Background and aim: Audience response (AR) systems are increasingly used in undergraduate medical education. However, high costs and complexity of conventional AR systems often limit their use. Here we present a novel AR system that is platform independent and does not require hardware clickers or additional software to be installed. Methods and results: “OnlineTED” was developed at Technische Universität München (TUM) based on Hypertext Preprocessor (PHP) with a My Structured Query Language (MySQL)-database as server- and Javascript as client-side programming languages. “OnlineTED” enables lecturers to create and manage question sets online and start polls in-class via a web-browser. Students can participate in the polls with any internet-enabled device (smartphones, tablet-PCs or laptops). A paper-based survey was conducted with undergraduate medical students and lecturers at TUM to compare "OnlineTED" with conventional AR systems using clickers. "OnlineTED" received above-average evaluation results by both students and lecturers at TUM and was seen on par or superior to conventional AR systems. The survey results indicated that up to 80% of students at TUM own an internet-enabled device (smartphone or tablet-PC) for participation in web-based AR technologies. Summary and Conclusion: “OnlineTED” is a novel web-based and platform-independent AR system for higher education that was well received by students and lecturers. As a non-commercial alternative to conventional AR systems it may foster interactive teaching in undergraduate education, in particular with large audiences. PMID:24575156

    Although reoperation rates for upper lid retraction surgery for thyroid eye disease (TED) typically range between 8% and 23%, there is little literature describing the outcomes of these second operations. In this retrospective observational cohort study, all patients that underwent surgery for upper eyelid retraction over a 14-year period at a single institution were included. Cases were included if a second eyelid retraction surgery was performed during the study period. Success of surgery was defined as a marginal reflex distance (MRD1) of 2.5 to 4.5 mm in each eye and less than 1 mm difference in MRD1 between the eyes. Overcorrection and undercorrection were defined as above and below these bounds, respectively. 72 eyes in 49 patients were included in the study. The mean age was 56.6 (±11.5) years. By definition, all patients had at least 1 lid lengthening surgery for upper eyelid retraction, and at least 1 subsequent surgery. For this second surgery, 61 eyes (85%) underwent retraction surgery and 11 eyes (15%) underwent ptosis surgery. After this second operation, 31% were undercorrected and 33% were overcorrected. A third surgery was performed in 19 eyes (25%), 12 had surgery for residual retraction and 7 for ptosis. After the third operation 10% of eyes were under corrected and 11% were over corrected. Four patients underwent a fourth surgery: one for retraction and three for ptosis. Success was noted in 35% after the second surgery and 44% after the third. Surgical success in eyelid retraction surgery increases from a second to a third consecutive surgery, and residual asymmetry was roughly equally distributed between over- and undercorrection.

  20. Ethos Formula: Liturgy and Rhetorics in the Work of Ted Shawn

    Directory of Open Access Journals (Sweden)

    Alexander Schwan

    2017-06-01

    Full Text Available Beginning with Giorgio Agamben’s alignment of ethics and potentiality, this essay questions the ethical dimension of gesture in the field of dance as an eminently potentiality-bound art form. This draws on Daniel Sibony’s concept of law and dance, according to which the body simultaneously repels and longs for the law as a nexus of heteronomous structures. I frame this through a revision of Aby Warburg’s rhetorical concept, pathos formula, into the corollary term, ethos formula, as the encoded movement patterns of ethical attitudes or comportments which are motivated by decision-making rather than emotional content. Do gestures and their citation in dance bear an ethical dimension similar to the encoded transmission of emotions through movement? This new concept of ethos formula finds an excellent example in the work of the American choreographer Ted Shawn (1891–1972. His strikingly hybrid use of ethos formula from the 19th century Catholic theorist François Delsarte and his parallel practice of quoting liturgical gestures from Protestant church services, pursues the ambiguity and uncanniness of modernity itself. For Shawn—like many other protagonists of modernist dance—argues on the one hand for freeing the body from the boundaries of classical ballet in the name of individual expression, and on the other hand for an instrumentalized body that still clings to principles of taxonomy and normativity.

    Communication campaigns are an accepted method for altering societal attitudes, increasing knowledge, and achieving social and behavioral change particularly within public health and the social sciences. The Image Gently(SM) campaign is a national education and awareness campaign in radiology designed to promote the need for and opportunities to decrease radiation to children when CT scans are indicated. In this article, the relatively new science of social marketing is reviewed and the theoretical basis for an effective communication campaign in radiology is discussed. Communication strategies are considered and the type of outcomes that should be measured are reviewed. This methodology has demonstrated that simple, straightforward safety messages on radiation protection targeted to medical professionals throughout the radiology community, utilizing multiple media, can affect awareness potentially leading to change in practice.

    Children with congenital or acquired heart disease can be exposed to relatively high lifetime cumulative doses of ionizing radiation from necessary medical imaging procedures including radiography, fluoroscopic procedures including diagnostic and interventional cardiac catheterizations, electrophysiology examinations, cardiac computed tomography (CT) studies, and nuclear cardiology examinations. Despite the clinical necessity of these imaging studies, the related ionizing radiation exposure could pose an increased lifetime attributable cancer risk. The Image Gently "Have-A-Heart" campaign is promoting the appropriate use of medical imaging studies in children with congenital or acquired heart disease while minimizing radiation exposure. The focus of this manuscript is to provide a comprehensive review of radiation dose management and CT performance in children with congenital or acquired heart disease.

    The objective of this study was to examine the influence of drug amount and mixing time on the homogeneity and content uniformity of a low-dose drug formulation during the dry mixing step using a new gentle-wing high-shear mixer. Moreover, the study investigated the influence of drug incorporation mode on the content uniformity of tablets manufactured by different methods. Albuterol sulfate was selected as a model drug and was blended with the other excipients at two different levels, 1% w/w and 5% w/w at impeller speed of 300 rpm and chopper speed of 3000 rpm for 30 min. Utilizing a 1 ml unit side-sampling thief probe, triplicate samples were taken from nine different positions in the mixer bowl at selected time points. Two methods were used for manufacturing of tablets, direct compression and wet granulation. The produced tablets were sampled at the beginning, middle, and end of the compression cycle. An analysis of variance analysis indicated the significant effect (p drug amount on the content uniformity of the powder blend and the corresponding tablets. For 1% w/w and 5% w/w formulations, incorporation of the drug in the granulating fluid provided tablets with excellent content uniformity and very low relative standard deviation (∼0.61%) during the whole tableting cycle compared to direct compression and granulation method with dry incorporation mode of the drug. Overall, gentle-wing mixer is a good candidate for mixing of low-dose cohesive drug and provides tablets with acceptable content uniformity with no need for pre-blending step.

    Full Text Available Considerado "guru dos estilos" e idealizador do conceito "supermercado de estilos", o antropólogo Ted Polhemus é reticente quanto aos "roubos fashion" pela hegemônica indústria da moda e acredita na força e no poder da comunicação visual de estilos e comportamentos como formas de expressão humana. Na conturbada e agitada década de 1960, o antropólogo anglo-americano Ted Polhemus, 57, trocou os EUA pela Inglaterra, em especial, a ensolarada Califórnia (para onde os jovens costumavam ir pela acinzentada e enevoada Londres. Esse contexto político-histórico de busca pela liberdade ideológica da era hippie e expansão da moda com o surgimento do prêt-à-porter possibilitou ao pesquisador estudar antropologia na Temple University, na Filadélfia. Em seguida, em Londres, desenvolveu seus estudos de mestrado sobre "Body Image and Adornment" (Imagem e Adorno do Corpo na prestigiada University of London.

    Full Text Available Inclusive differentiated instruction is a new model of didactic instruction, theoretically described and established in this paper for the first time, after being experimentally verified through teaching of the mother tongue (instruction in reading and literature. Inclusive individually planned instruction is based on a phenomenological and constructivist didactic instructional paradigm. This type of teaching is essentially developmental and person-oriented. The key stages of inclusive differentiated instruction of literature are: 1 recognition of individual students' potential and educational needs regarding reading and work on literary texts; 2 planning and preparation of inclusive individually planned instruction in reading and literature; 3 actual class teaching of lessons thus prepared; and 4 evaluation of the student achievement following inclusive differentiated instruction in reading and literature. A highly important element of the planning and preparation of inclusive differentiated instruction is the creation of student profiles and inclusive individualized syllabi. Individualized syllabi specify the following: 1. a brief student profile; 2. the student position on the continuum of the learning outcomes of instruction in the Serbian language; 3. reverse-engineered macro-plan stages of instruction in the Serbian language (3.1. identifying expected outcomes and fundamental qualities of learners' work, 3.2. defining acceptable proofs of their realisation, 3.3. planning learning and teaching experiences, and 3.4. providing material and technical requisites for teaching; 4 the contents and procedure of individualized lessons targeting the student; 5 a plan of syllabus implementation monitoring and evaluation. The continuum of the learning outcomes of inclusive differentiated instruction in literature exists at three main levels, A, B and C. The three levels are: A reading techniques and learning about the main literary theory concepts; B

    2012-01-01

    Document available in extended abstract form only. The TED experiment is a heating experiment in Callovo-Oxfordian Clay performed in the Meuse Haute Marne underground research laboratory. It was set up by Andra to confirm the results obtained in a previous thermal experiment (TER). The main objectives are: characterisation of the thermal properties of intact argillite, identification of the Thermo-Hydro-Mechanical (THM) coupling parameters, improvement of the understanding of THM behaviour and comparison of parameters measured in-situ and in the laboratory. The three heaters in the TED experiment were installed parallel at a distance of about 2.7 m to reproduce as closely as possible the real storage case (HA cells). This arrangement should allow the verification of: i) the superposition of several temperature fields generated by the three heaters and ii) the overpressure generated in the symmetry planes between the three heaters. Three heaters 4 m long and 0.143 m diameter have been installed in parallel boreholes drilled form GED gallery. To limit the influence of the conditions prevailing in the gallery, a distance of 12 m have been left between the GED wall and the closest extremity of the heaters. Rock has been intensively instrumented within a zone of 15 m around the heaters. There are 108 thermal sensors, 10 pore pressure sensors, 2 extensometers/inclinometers, placed in 13 different small diameter boreholes (56 mm). 11 boreholes were filled with bentonite (those containing thermal and pore pressure sensors) and 2 of them left open (those equipped with extensometer/inclinometers). First heating started on 22 January 2010 at the central heater and consists of three steps: 120 days at 180 W, 150 days at 300 W and one last period at 600 W. The two lateral heaters have been switched on after 14 months following the same heating sequence. The concept and the results of the TED experiment are fully described in a companion paper.

    1988-01-01

    In spite of the regulations and the safety provisions taken, accidents are not entirely avoidable in the transport of hazardous materials. For managing an accident and preventing further hazards after release of dangerous substances, the vehicle drivers must carry with them the accident management instruction sheets, which give instructions on immediate counter measures to be taken by the driver, and on information to be given to the police and the fire brigades. The article in hand discusses the purpose, the contents, and practice-based improvement of this collection of instruction sheets. Particular reference is given to the newly revised version of June 15, 1988 (Verkehrsblatt 1/88) of the 'Directives for setting up accident management instruction sheets - written instructions - for road transport of hazardous materials', as issued by the Federal Ministry of Transport.

    Mahabaduge, Hasitha; Haslam, Jeanne

    Supplemental instruction utilizes peer-assisted study sessions to provide review sessions on course material and an opportunity to discuss and work out problems. The impact of supplemental instruction on student performance is well researched and used in a large number of universities around the world due to its proven success. However, the impact of the student leader who plays a significant role in this model is rarely discussed in the literature. We present a case study on the impact of student leader on the success of supplemental instruction model. This case study was done for an Introductory Physics course correlating student performance and the supplemental instruction sessions they attended. Further analysis revealed that the academic performance and work ethics of the student leader has a significant impact on the success of the supplemental instruction model. Important factors to consider when selecting a student leader, the challenges and possible remedies will also be discussed.

  4. The critical role of relationship in education

    Directory of Open Access Journals (Sweden)

    Francois Wessels

    2015-09-01

    Full Text Available A TED talk by Susan Savage-Rumbaugh entitled ‘The gentle genius of the bonobos’ tells the story of the learning ability of these gentle primates. Although these animals were never deliberately taught any skills – cognitive, linguistic or technical – they managed to learn a vast amount from the scientists in the program by just observing, experimenting and imitating them. And the key to this learning process was the significance these humans had in the lives of the bonobos. The relationship between the scientists and the bonobos was therefore key to the learning experience and the learning process. This reminded me of the success stories I have witnessed within our therapist training program at the counselling centre where I have been lecturing. We used to train pastoral therapists within the narrative paradigm. Within this paradigm, reality is considered to be socially constructed, thus emphasising the relational nature of identity, agency and knowledge. Aligning the ‘teaching methodology’ with this epistemology invariably requires a participatory approach to training, which in our context led to the adoption of seminars rather than lectures, and a conversational style of learning (with the lecturer – or more aptly, the facilitator – becoming a co-learner!. This article will now explore what the effect of relationship building as a deliberate prerequisite for learning might be on learner agency.

  5. The impact of inquiry-based instructional professional development upon instructional practice: An action research study

    Science.gov (United States)

    Broom, Frances A.

    This mixed method case study employs action research, conducted over a three month period with 11 elementary math and science practitioners. Inquiry as an instructional practice is a vital component of math and science instruction and STEM teaching. Teachers examined their beliefs and teaching practices with regard to those instructional factors that influence inquiry instruction. Video-taped lessons were compared to a rubric and pre and post questionnaires along with two interviews which informed the study. The results showed that while most beliefs were maintained, teachers implemented inquiry at a more advanced level after examining their teaching and reflecting on ways to increase inquiry practices. Because instructional practices provide only one component of inquiry-based instruction, other components need to be examined in a future study.

  14. Instructable autonomous agents. Ph.D. Thesis

    Science.gov (United States)

    Huffman, Scott Bradley

    1994-01-01

    In contrast to current intelligent systems, which must be laboriously programmed for each task they are meant to perform, instructable agents can be taught new tasks and associated knowledge. This thesis presents a general theory of learning from tutorial instruction and its use to produce an instructable agent. Tutorial instruction is a particularly powerful form of instruction, because it allows the instructor to communicate whatever kind of knowledge a student needs at whatever point it is needed. To exploit this broad flexibility, however, a tutorable agent must support a full range of interaction with its instructor to learn a full range of knowledge. Thus, unlike most machine learning tasks, which target deep learning of a single kind of knowledge from a single kind of input, tutorability requires a breadth of learning from a broad range of instructional interactions. The theory of learning from tutorial instruction presented here has two parts. First, a computational model of an intelligent agent, the problem space computational model, indicates the types of knowledge that determine an agent's performance, and thus, that should be acquirable via instruction. Second, a learning technique, called situated explanation specifies how the agent learns general knowledge from instruction. The theory is embodied by an implemented agent, Instructo-Soar, built within the Soar architecture. Instructo-Soar is able to learn hierarchies of completely new tasks, to extend task knowledge to apply in new situations, and in fact to acquire every type of knowledge it uses during task performance - control knowledge, knowledge of operators' effects, state inferences, etc. - from interactive natural language instructions. This variety of learning occurs by applying the situated explanation technique to a variety of instructional interactions involving a variety of types of instructions (commands, statements, conditionals, etc.). By taking seriously the requirements of flexible

    Van Dessel, Pieter; Mertens, Gaëtan; Smith, Colin Tucker; De Houwer, Jan

    2017-09-01

    The mere exposure effect refers to the well-established finding that people evaluate a stimulus more positively after repeated exposure to that stimulus. We investigated whether a change in stimulus evaluation can occur also when participants are not repeatedly exposed to a stimulus, but are merely instructed that one stimulus will occur frequently and another stimulus will occur infrequently. We report seven experiments showing that (1) mere exposure instructions influence implicit stimulus evaluations as measured with an Implicit Association Test (IAT), personalized Implicit Association Test (pIAT), or Affect Misattribution Procedure (AMP), but not with an Evaluative Priming Task (EPT), (2) mere exposure instructions influence explicit evaluations, and (3) the instruction effect depends on participants' memory of which stimulus will be presented more frequently. We discuss how these findings inform us about the boundary conditions of mere exposure instruction effects, as well as the mental processes that underlie mere exposure and mere exposure instruction effects.

    This report provides information to nuclear power plant training managers and their staffs concerning the job performance requirements of instructional personnel to implement prformance-based training programs (also referred to as the Systems Approach Training). The information presented in this report is a compilation of information and lessons learned in the nuclear power industry and in other industries using performance-based training programs. The job performance requirements in this report are presented as instructional skills objectives. The process used to develop the instructional skills objectives is described. Each objective includes an Instructional Skills Statement describing the behavior that is expected and an Instructional Skills Standard describing the skills/knowledge that the individual should possess in order to have achieved mastery. The instructional skills objectives are organized according to the essential elements of the Systems Approach to Training and are cross-referenced to three categories of instructional personnel: developers of instruction, instructors, and instructional managers/supervisors. Use of the instructional skills objectives is demonstrated for reviewing instructional staff training and qualification programs, developing criterion-tests, and reviewing the performance and work products of individual staff members. 22 refs

    The sets of track etched detectors based (TED) spectrometer's of the linear energy transfer (LET) have been, together with two types of thermoluminescent detectors (TLD)and MDU- Liulin energy deposition spectrometer exposed in the C 290 MeV/n and Ne 400 MeV/n ion beams at the HlMAC installation at NIRS, Chiba, Japan. The experiment has been performed in the frame of NPI project 20P241 agreed by HlMAC P AC at the beginning of 2008 year. Up to now, moxstle only results obtained in C-ion beam have been treated and analyzed. Sets of TED spectrometer's and TLD detectors have been exposed in 19 depths in the C-ion beam with expected LET values of primary particles from 13 keV/μm in water, through the Bragg peak area up to two depth behind the Bragg peak. The contribution of fragments to total number of events, and to the energy absorbed in Si has been determined, when possible separately for different fragments. In all cases also total contribution of fragments (and other secondary particles) to the total number of energy deposition events and to the absorbed dose has been estimated. LET and energy deposition spectra obtained will be compared together , a good agreement of data has bee stated. Some of results have been also compared with those obtained by calculation by means of PHITS code. (authors)

    Full Text Available This research compared the effects of two types of instruction: Processing Instruction (PI and Meaning-based Output Instruction (MOI on the interpretation and production of English passive structures.  Ninety EFL intermediate tertiary level female students (PI group= 30, MOI group= 30 and control group = 30 participated in this study. The instruments were a proficiency test, a test to assess English passive structures and two instructional materials (PI and MOI. The data were analyzed by running one-way analysis of variance (ANOVA and mixed between-within ANOVA. The study indicated the effectiveness of PI and MOI on English passive structures. PI had considerable enhancement on interpretation tasks all the time. It supported the use of PI rather than the use of traditional instructions in which mechanical components were emphasized. Also, the PI and MOI had long term effects on the interpretation and production of English passive sentences.  This study supported the use of PI and MOI rather than the use of traditional instruction (TI in EFL settings. The implication for particularly classroom teaching is that successful grammar instruction has to related to ultimate learning outcomes. Also, creating communicative tasks to offer opportunities for teaching grammar can lead to long-lasting learning effects.

    2014-01-01

    Graphical abstract: - Abstract: Water-oxygen electrochemistry is at the heart of key renewable energy technologies (fuel cells, electrolyzers, and metal-air batteries) due to the sluggish kinetics of oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Although much effort has been devoted to the development of improved bifunctional electrocatalysts, an inexpensive, highly active oxygen electrocatalyst, however, remains to be a challenge. In this paper, we present a facile and robust method to create gently reduced graphene oxide incorporated into cobalt oxalate microstructures (CoC 2 O 4 /gRGO) and demonstrate its excellent and stable electrocatalytic activity in both OER and ORR, arising from the inherent properties of the components and their physicochemical interaction. Our synthesis technique also explores a single pot method to partially reduce graphene oxide and form CoC 2 O 4 structures while maintaining the solution processability of reduced graphene oxide. While the OER activity of CoC 2 O 4 /gRGO is exclusively due to CoC 2 O 4 , which transformed into OER-active Co species, the combination with gRGO significantly improves OER stability. On the other hand, CoC 2 O 4 /gRGO exhibits synergistic effect towards ORR, via a quasi-four-electron pathway, leading to a slightly higher ORR limiting current than Pt/C. Remarkably, gRGO offers dual functionality, contributing to ORR activity via the N-functional groups and also enhancing OER stability through the gRGO coating around CoC 2 O 4 structures. Our results suggest a new class of metal-carbon composite that has the potential to be alternative bifunctional catalysts for regenerative fuel cells and metal-air batteries

  7. Teaching about teaching and instruction on instruction: a challenge for health sciences library education.

    2012-10-01

    This is a review of the master's-level curricula of the fifty-eight America Library Association-accredited library and information science programs and iSchools for evidence of coursework and content related to library instruction. Special emphasis is placed on the schools and programs that also offer coursework in medical or health sciences librarianship. Fifty-eight school and program websites were reviewed. Course titles and course descriptions for seventy-three separate classes were analyzed. Twenty-three syllabi were examined. All North American library education programs offer at least one course in the general area of library instruction; some programs offer multiple courses. No courses on instruction, however, are focused directly on the specialized area of health sciences librarianship. Master's degree students can take appropriate classes on library instruction, but the medical library profession needs to offer continuing education opportunities for practitioners who want to have specific instruction for the specialized world of the health sciences.

    The objective of this exploratory investigation was to examine the nature of writing instruction in kindergarten classrooms and to describe student writing outcomes at the end of the school year. Participants for this study included 21 teachers and 238 kindergarten children from nine schools. Classroom teachers were videotaped once each in the fall and winter during the 90 minute instructional block for reading and language arts to examine time allocation and the types of writing instructional practices taking place in the kindergarten classrooms. Classroom observation of writing was divided into student-practice variables (activities in which students were observed practicing writing or writing independently) and teacher-instruction variables (activities in which the teacher was observed providing direct writing instruction). In addition, participants completed handwriting fluency, spelling, and writing tasks. Large variability was observed in the amount of writing instruction occurring in the classroom, the amount of time kindergarten teachers spent on writing and in the amount of time students spent writing. Marked variability was also observed in classroom practices both within and across schools and this fact was reflected in the large variability noted in kindergartners’ writing performance.

    The Bechtel Hanford, Inc. facility transition instruction was initiated in response to the need for a common, streamlined process for facility transitions and to capture the knowledge and experience that has accumulated over the last few years. The instruction serves as an educational resource and defines the process for transitioning facilities to long-term surveillance and maintenance (S and M). Generally, these facilities do not have identified operations missions and must be transitioned from operational status to a safe and stable configuration for long-term S and M. The instruction can be applied to a wide range of facilities--from process canyon complexes like the Plutonium Uranium Extraction Facility or B Plant, to stand-alone, lower hazard facilities like the 242B/BL facility. The facility transition process is implemented (under the direction of the US Department of Energy, Richland Operations Office [RL] Assistant Manager-Environmental) by Bechtel Hanford, Inc. management, with input and interaction with the appropriate RL division and Hanford site contractors as noted in the instruction. The application of the steps identified herein and the early participation of all organizations involved are expected to provide a cost-effective, safe, and smooth transition from operational status to deactivation and S and M for a wide range of Hanford Site facilities

    Increased investment in ethics education has prompted a variety of instructional objectives and frameworks. Yet, no systematic procedure to classify these varying instructional approaches has been attempted. In the present study, a quantitative clustering procedure was conducted to derive a typology of instruction in ethics education. In total, 330 ethics training programs were included in the cluster analysis. The training programs were appraised with respect to four instructional categories including instructional content, processes, delivery methods, and activities. Eight instructional approaches were identified through this clustering procedure, and these instructional approaches showed different levels of effectiveness. Instructional effectiveness was assessed based on one of nine commonly used ethics criteria. With respect to specific training types, Professional Decision Processes Training (d = 0.50) and Field-Specific Compliance Training (d = 0.46) appear to be viable approaches to ethics training based on Cohen's d effect size estimates. By contrast, two commonly used approaches, General Discussion Training (d = 0.31) and Norm Adherence Training (d = 0.37), were found to be considerably less effective. The implications for instruction in ethics training are discussed.

    Patients with intestinal failure associated with short bowel syndrome (SBS-IF) require parenteral support (PS) to maintain fluid balance or nutrition. Teduglutide (TED) reduced PS requirements in patients with SBS-IF in the randomized, placebo (PBO)-controlled STEPS study (NCT00798967) and its 2-year, open-label extension, STEPS-2 (NCT00930644). STEPS-3 (NCT01560403), a 1-year, open-label extension study in patients with SBS-IF who completed STEPS-2, further monitored the safety and efficacy of TED (0.05 mg/kg/day). Baseline was the start of TED treatment, in either STEPS or STEPS-2. At the end of STEPS-3, patients treated with TED in both STEPS and STEPS-2 (TED-TED) received TED for ≤42 months, and patients treated with TED only in STEPS-2 (no TED treatment [NT]/PBO-TED) received TED for ≤36 months. Fourteen patients enrolled (TED-TED, n = 5; NT/PBO-TED, n = 9) and 13 completed STEPS-3. At the last dosing visit, mean (SD) PS was reduced from baseline by 9.8 (14.4 [50%]) and 3.9 (2.8 [48%]) L/week in TED-TED and NT/PBO-TED, respectively. Mean (SD) PS infusions decreased by 3.0 (4.6) and 2.1 (2.2) days per week from baseline in TED-TED and NT/PBO-TED, respectively. Two patients achieved PS independence; 2 additional patients who achieved independence in STEPS-2 maintained enteral autonomy throughout STEPS-3. All patients reported ≥1 treatment-emergent adverse event (TEAE); 3 patients had TEAEs that were reported as treatment related. No patient had a treatment-related treatment-emergent serious AE. Long-term TED treatment yielded a safety profile consistent with previous studies, sustained efficacy, and a further decline in PS requirements. © 2018 The Authors.

    Conflicts are an undesirable yet common aspect of daily interactions with wide-ranging negative consequences. The present research aimed to examine the buffering effect of experimentally instructed reappraisal on self-reported, physiological and behavioral stress indices during interpersonal conflicts, taking into account habitual emotion regulation strategies. For this, 145 participants experienced a standardized laboratory conflict with the instruction to either reappraise (n = 48), to suppress (n = 50), or with no instruction (n = 47) while cardiovascular and neuroendocrine measures were taken. Participants were allowed to eat sweet and salty snacks during the conflict situation. Prior to as well as after the conflict, participants reported on their subjective stress level. Reappraisal instructions were only effective for high habitual reappraisers who exhibited lower cardiovascular and cortisol reactivity and demonstrated fewer snack-eating behaviors under reappraisal instructions than under suppression or no instructions. The opposite pattern emerged for low habitual reappraisers. Neither experimentally instructed nor habitual reappraisal by itself reduced the negative effects of conflicts. Our findings complement the literature on the diverging effects of instructed reappraisal in tense social interactions. © 2018 Society for Psychophysiological Research.

  5. Temperature And Wind Velocity Oscillations Along a Gentle Slope During Sea-Breeze Events

    Bastin, Sophie; Drobinski, Philippe

    2005-03-01

    The flow structure on a gentle slope at Vallon d’Ol in the northern suburbs of Marseille in southern France has been documented by means of surface wind and temperature measurements collected from 7 June to 14 July 2001 during the ESCOMPTE experiment. The analysis of the time series reveals temperature and wind speed oscillations during several nights (about 60--90 min oscillation period) and several days (about 120-180 min oscillation period) during the whole observing period. Oscillating katabatic winds have been reported in the literature from theoretical, experimental and numerical studies. In the present study, the dynamics of the observed oscillating katabatic winds are in good agreement with the theory.In contrast to katabatic winds, no daytime observations of oscillating anabatic upslope flows have ever been published to our knowledge, probably because of temperature inversion break-up that inhibits upslope winds. The present paper shows that cold air advection by a sea breeze generates a mesoscale horizontal temperature gradient, and hence baroclinicity in the atmosphere, which then allows low-frequency oscillations, similar to a katabatic flow. An expression for the oscillation period is derived that accounts for the contribution of the sea-breeze induced mesoscale horizontal temperature gradient. The theoretical prediction of the oscillation period is compared to the measurements, and good agreement is found. The statistical analysis of the wind flow at Vallon d’Ol shows a dominant north-easterly to easterly flow pattern for nighttime oscillations and a dominant south-westerly flow pattern for daytime oscillations. These results are consistent with published numerical simulation results that show that the air drains off the mountain along the maximum slope direction, which in the studied case is oriented south-west to north-east.

    2017-02-01

    In an effort to maximize a student’s academic growth, one of the tools available to educators is the explicit instruction. Explicit instruction is marked by a series of support or scaffold, where the students will be guided through the learning process with a clear statement of purpose and a reason for learning new skills, a clear explanation and demonstration of learning targets, supported and practiced with independent feedback until mastery has been achieved. The technology development trend of todays, requires an adjustment in the development of learning object that supports the achievement of explicit instruction targets. This is where the gamification position is. In the role as a pedagogical strategy, the use of gamification preformance study class is still relatively new. Gamification not only use the game elements and game design techniques in non-game contexts, but also to empower and engage learners with the ability of motivation on learning approach and maintains a relaxed atmosphere. With using Reseach and Development methods, this paper presents the integration of technology (which in this case using the concept of gamification) in explicit instruction settings and the impact on the improvement of students’ understanding.

    The instructions subjects receive can have a large effect on experimentally measured color constancy, but the nature of these effects and how their existence should inform our understanding of color perception remains unclear. We used a factorial design to measure how instructional effects on constancy vary with experimental task and stimulus set. In each of 2 experiments, we employed both a classic adjustment-based asymmetric matching task and a novel color selection task. Four groups of naive subjects were instructed to make adjustments/selections based on (a) color (neutral instructions); (b) the light reaching the eye (physical spectrum instructions); (c) the actual surface reflectance of an object (objective reflectance instructions); or (d) the apparent surface reflectance of an object (apparent reflectance instructions). Across the 2 experiments we varied the naturalness of the stimuli. We find clear interactions between instructions, task, and stimuli. With simplified stimuli (Experiment 1), instructional effects were large and the data revealed 2 instruction-dependent patterns. In 1 (neutral and physical spectrum instructions) constancy was low, intersubject variability was also low, and adjustment-based and selection-based constancy were in agreement. In the other (reflectance instructions) constancy was high, intersubject variability was large, adjustment-based constancy deviated from selection-based constancy and for some subjects selection-based constancy increased across sessions. Similar patterns held for naturalistic stimuli (Experiment 2), although instructional effects were smaller. We interpret these 2 patterns as signatures of distinct task strategies-1 is perceptual, with judgments based primarily on the perceptual representation of color; the other involves explicit instruction-driven reasoning.

  9. Scaffolding in Assisted Instruction

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available On-The-Job Training, developed as direct instruction, is one of the earliest forms of training. This method is still widely in use today because it requires only a person who knows how to do the task, and the tools the person uses to do the task. This paper is intended to be a study of the methods used in education in Knowledge Society, with more specific aspects in training the trainers; as a result of this approach, it promotes scaffolding in assisted instruction as a reflection of the digital age for the learning process. Training the trainers in old environment with default techniques and designing the learning process in assisted instruction, as an application of the Vygotskian concept of the zone of proximal development (ZPD to the area of computer literacy for the younger users, generate diversity in educational communities and requires standards for technology infrastructure, standards for the content, developed as a concepts map, and applications for personalized in-struction, based on ZPD theory.

  10. Instructional leaders for all? High school science department heads and instructional leadership across all science disciplines

    Science.gov (United States)

    Sanborn, Stephen

    Many high school science departments are responding to changes in state standards with respect to both curricular content and instructional practices. In the typical American high school organization, the academic department head is ideally positioned to influence change in the instructional practices of teachers within the department. Even though science department heads are well situated to provide leadership during this period of transition, the literature has not addressed the question of how well science department heads believe they can provide instructional leadership for all of the teachers in their department, whether they are teaching within and outside of the head's own sub-discipline. Nor is it known how science department heads view the role of pedagogical content knowledge in teaching different science disciplines. Using an online survey comprised of 26 objective questions and one open response question, a 54-respondent sample of science department heads provided no strong consensus regarding their beliefs about the role of pedagogical content knowledge in science instruction. However, science department heads expressed a significant difference in their views about their capacity to provide instructional leadership for teachers sharing their science content area compared to teachers instructing other science content areas. Given wide-spread science education reform efforts introduced in response to the Next Generation Science Standards, these findings may serve to provide some direction for determining how to best support the work of science department heads as they strive to provide instructional leadership for the teachers in their departments.

  11. Developing principles of sustainability and stakeholder engagement for "gentle" remediation approaches: the European context.

    Gentle Remediation Options (GRO) are risk management strategies or techniques for contaminated sites that result in no gross reduction in soil functionality (or a net gain) as well as risk management. Intelligently applied GROs can provide: (a) rapid risk management via pathway control, through containment and stabilisation, coupled with a longer term removal or immobilisation/isolation of the contaminant source term; and (b) a range of additional economic (e.g. biomass generation), social (e.g. leisure and recreation) and environmental (e.g. CO2 sequestration) benefits. In order for these benefits to be optimised or indeed realised, effective stakeholder engagement is required. This paper reviews current sector practice in stakeholder engagement and its importance when implementing GRO and other remediation options. From this, knowledge gaps are identified, and strategies to promote more effective stakeholder engagement during GRO application are outlined. Further work is required on integrating stakeholder engagement strategies into decision support systems and tools for GRO (to raise the profile of the benefits of effective stakeholder engagement and participation, particularly with sector professionals), and developing criteria for the identification of different stakeholder profiles/categories. Demonstrator sites can make a significant contribution to stakeholder engagement via providing evidence on the effectiveness of GRO under varying site contexts and conditions. Effective and sustained engagement strategies however will be required to ensure that site risk is effectively managed over the longer-term, and that full potential benefits of GRO (e.g. CO2 sequestration, economic returns from biomass generation and "leverage" of marginal land, amenity and educational value, ecosystem services) are realised and communicated to stakeholders.

  12. Evaluation of a Theory of Instructional Sequences for Physics Instruction

    Science.gov (United States)

    Wackermann, Rainer; Trendel, Georg; Fischer, Hans E.

    2010-05-01

    The background of the study is the theory of basis models of teaching and learning, a comprehensive set of models of learning processes which includes, for example, learning through experience and problem-solving. The combined use of different models of learning processes has not been fully investigated and it is frequently not clear under what circumstances a particular model should be used by teachers. In contrast, the theory under investigation here gives guidelines for choosing a particular model and provides instructional sequences for each model. The aim is to investigate the implementation of the theory applied to physics instruction and to show if possible effects for the students may be attributed to the use of the theory. Therefore, a theory-oriented education programme for 18 physics teachers was developed and implemented in the 2005/06 school year. The main features of the intervention consisted of coaching physics lessons and video analysis according to the theory. The study follows a pre-treatment-post design with non-equivalent control group. Findings of repeated-measures ANOVAs show large effects for teachers' subjective beliefs, large effects for classroom actions, and small to medium effects for student outcomes such as perceived instructional quality and student emotions. The teachers/classes that applied the theory especially well according to video analysis showed the larger effects. The results showed that differentiating between different models of learning processes improves physics instruction. Effects can be followed through to student outcomes. The education programme effect was clearer for classroom actions and students' outcomes than for teachers' beliefs.

    Gvozdjak, L.; Hanulova, L.; Jankovicova, A.; Scepanek, L.

    1983-01-01

    The DIDAK system has been developed for the instruction and training of specialized personnel of nuclear power plants. The structure of the instruction system comprises three processes: the author process, the instruction process and the administration process. Author processes provide the didactic data structure with instruction texts. In the text data base the instruction material is stored in 6 direct access nonformatted files. The instruction system receives information from the text data base and presents it to the student. According to the student's response it creates the preconditions for the further operation of the system which it stores in the data base for administration of instruction. This base contains data on the identification of students, on the instruction process of the individual and the instruction process as a whole. Administrative processes take place in the final stage. They provide information on the general course of instruction and make final evaluations. From the data base of products of the instruction process the said administrative processes produce output information for the teacher. The subject matter of each subject is divided into a finite number of elementary units of subject matter. Each elementary unit provides basic information on the explained subject matter and is followed by a check of the student's knowledge. In dependence on the results of this check the student either advances to a higher level elementary unit or proceeds to an alternative branch of the initial unit. (E.S.)

  12. How faculty learn about and implement research-based instructional strategies: The case of Peer Instruction

    Science.gov (United States)

    Dancy, Melissa; Henderson, Charles; Turpen, Chandra

    2016-06-01

    [This paper is part of the Focused Collection on Preparing and Supporting University Physics Educators.] The lack of knowledge about how to effectively spread and sustain the use of research-based instructional strategies is currently a significant barrier to the improvement of undergraduate physics education. In this paper we address this lack of knowledge by reporting on an interview study of 35 physics faculty, of varying institution types, who were self-reported users of, former users of, or knowledgeable nonusers of the research-based instructional strategy Peer Instruction. Interview questions included in this analysis focused on the faculty's experiences, knowledge, and use of Peer Instruction, along with general questions about current and past teaching methods used by the interviewee. The primary findings include the following: (i) Faculty self-reported user status is an unreliable measure of their actual practice. (ii) Faculty generally modify specific instructional strategies and may modify out essential components. (iii) Faculty are often unaware of the essential features of an instructional strategy they claim to know about or use. (iv) Informal social interactions provide a significant communication channel in the dissemination process, in contrast to the formal avenues of workshops, papers, websites, etc., often promoted by change agents, and (v) experience with research-based strategies as a graduate student or through curriculum development work may be highly impactful. These findings indicate that educational transformation can be better facilitated by improving communication with faculty, supporting effective modification by faculty during implementation, and acknowledging and understanding the large impact of informal social interactions as a mode of dissemination.

    Concetta A. DePaolo, Ph.D.

    2006-07-01

    Full Text Available Recent technological advances have led to changes in how instruction is delivered. Such technology can create opportunities to enhance instruction and make instructors more efficient in performing instructional tasks, especially if the technology is easy to use and requires no training. One such technology, web-based survey software, is extremely accessible for anyone with basic computer skills. Web-based survey software can be used for a variety of instructional purposes to streamline instructor tasks, as well as enhance instruction and communication with students. Following a brief overview of the technology, we discuss how Web Forms from nTreePoint can be used to conduct instructional surveys, collect course feedback, conduct peer evaluations of group work, collect completed assignments, schedule meeting times among multiple people, and aid in pedagogical research. We also discuss our experiences with these tasks within traditional on-campus courses and how they were enhanced or expedited by the use of web-based survey software.

  18. Effective instruction for English learners.

    Science.gov (United States)

    Calderón, Margarita; Slavin, Robert; Sánchez, Marta

    2011-01-01

    The fastest-growing student population in U.S. schools today is children of immigrants, half of whom do not speak English fluently and are thus labeled English learners. Although the federal government requires school districts to provide services to English learners, it offers states no policies to follow in identifying, assessing, placing, or instructing them. Margarita Calderón, Robert Slavin, and Marta Sánchez identify the elements of effective instruction and review a variety of successful program models. During 2007-08, more than 5.3 million English learners made up 10.6 percent of the nation's K-12 public school enrollment. Wide and persistent achievement disparities between these English learners and English-proficient students show clearly, say the authors, that schools must address the language, literacy, and academic needs of English learners more effectively. Researchers have fiercely debated the merits of bilingual and English-only reading instruction. In elementary schools, English learners commonly receive thirty minutes of English as a Second Language (ESL) instruction but attend general education classes for the rest of the day, usually with teachers who are unprepared to teach them. Though English learners have strikingly diverse levels of skills, in high school they are typically lumped together, with one teacher to address their widely varying needs. These in-school factors contribute to the achievement disparities. Based on the studies presented here, Calderón, Slavin, and Sánchez assert that the quality of instruction is what matters most in educating English learners. They highlight comprehensive reform models, as well as individual components of these models: school structures and leadership; language and literacy instruction; integration of language, literacy, and content instruction in secondary schools; cooperative learning; professional development; parent and family support teams; tutoring; and monitoring implementation and outcomes

    A recent consensus statement from the European Group on Graves' Orbitopathy recommends referring all patients with thyroid eye disease (TED), except the mildest cases, to a specialist multidisciplinary clinic. To study the patients' experiences of accessing services for the treatment of TED in the UK. A postal questionnaire survey of 395 members of two patients support organisations for TED in the UK, the TED Charitable Trust and the British Thyroid Foundation. The response rate was 67%. The majority of responders were females (91%) and aged above 45 (74%). There were delays in the diagnosis and referral. In 26% of responders, the time lapsed from the first symptoms to the diagnosis of TED for over 12 months. There was a wide variation in the type of clinic and healthcare professionals involved in the treatment of TED. Only 25% of the responders attended a specialist TED clinic. Out of these, 33% waited over 6 months from the first consultation with a doctor to being seen at a specialist TED clinic. Only 56% of responders were satisfied with the treatment they received for TED. More responders who had attended a specialist TED clinic were satisfied with the treatment than those who had not attended a specialist clinic (67 vs 52%, P<0.05). Only a minority of patients with TED are treated at a specialist TED clinic in the UK. Those patients who are treated at a specialist TED clinic are more likely to be satisfied with the treatment.

  11. Differentiating Science Instruction: Secondary science teachers' practices

    Science.gov (United States)

    Maeng, Jennifer L.; Bell, Randy L.

    2015-09-01

    This descriptive study investigated the implementation practices of secondary science teachers who differentiate instruction. Participants included seven high school science teachers purposefully selected from four different schools located in a mid-Atlantic state. Purposeful selection ensured participants included differentiated instruction (DI) in their lesson implementation. Data included semi-structured interviews and field notes from a minimum of four classroom observations, selected to capture the variety of differentiation strategies employed. These data were analyzed using a constant-comparative approach. Each classroom observation was scored using the validated Differentiated Instruction Implementation Matrix-Modified, which captured both the extent to which critical indicators of DI were present in teachers' instruction and the performance levels at which they engaged in these components of DI. Results indicated participants implemented a variety of differentiation strategies in their classrooms with varying proficiency. Evidence suggested all participants used instructional modifications that required little advance preparation to accommodate differences in students' interests and learning profile. Four of the seven participants implemented more complex instructional strategies that required substantial advance preparation by the teacher. Most significantly, this study provides practical strategies for in-service science teachers beginning to differentiate instruction and recommendations for professional development and preservice science teacher education.

    2016-01-01

    Increasing instruction time in school is a central element in the attempts of many governments to improve student learning, but prior research—mainly based on observational data—disputes the effect of this approach and points out the potential negative effects on student behavior. Based on a large......-scale, cluster-randomized trial, we find that increasing instruction time increases student learning and that a general increase in instruction time is at least as efficient as an expert-developed, detailed teaching program that increases instruction with the same amount of time. These findings support the value...... of increased instruction time....

    To investigate function and morphology of the meibomian gland (MG) in patients with thyroid eye disease (TED). In this prospective case series study, patients with unilateral or bilateral TED were consecutively enrolled. The diagnosis of TED was based on the typical orbital findings and/or radiographic evidence. The disease activity of TED was classified according to the clinical activity score (CAS). Degrees of lagophthalmos and exophthalmos, blinking rates, and results of the Schirmer test 1 were also recorded. All patients completed the SPEED questionnaire and underwent MG assessment, including lipid layer thickness (LLT), MG dropout (MGd), and MG expression. In total 31 eyes from 17 patients with unilateral or bilateral TED were included. Patients were divided into inactive TED (CAS 0-1; 20 eyes from 11 patients) and active TED (CAS 2-3, 11 eyes from 6 patients) groups. MGd was significantly more severe in the active TED than the inactive TED group [Median (Inter-quartile region): 3.0 (2.0-3.0) vs. 2.0 (1.0-2.0) degree, P = 0.04]. However, patients with active TED had thicker LLT than those with inactive TED (90.0 [80.0-100.0] vs. 65.0 [47.8-82.5] nm, P = 0.02), and LLT was positively correlated with lagophthalmos (r = 0.37, P = 0.04). Patients with active TED had more severe MGd, but thicker LLT. Active TED may cause periglandular inflammation of MGs, leading to MGd, but compensatory secretion from residual MGs and lagophthalmos-induced forceful blinking might temporarily release more lipids over the tear film.

    When multiple energy systems execute optimization instructions simultaneously, and the same equipment is Shared, the instruction conflict may occur. Aiming at the above problems, taking into account the control objectives of each system, the characteristics of different systems, such as comprehensive clean energy, energy efficiency, and peak filling, etc., designed the instruction coordination mechanism for the daemon. This mechanism mainly acts on the main station of the system, and form a final optimization instruction. For some specific scenarios, the collaboration mechanism of unlocking the terminal is supplemented. The mechanism determines the specific execution instructions based on the arrival time of the instruction. Finally, the experiment in Tianjin eco-city shows that this algorithm can meet the instruction and collaboration requirements of multi-energy systems, and ensure the safe operation of the equipment.

  6. Ted Irving and the Precambrian continental drift of (within?) the Canadian Shield

    Science.gov (United States)

    Hoffman, P. F.

    2014-12-01

    Ted Irving was no stranger to the Precambrian when he began paleomagnetic studies in the Canadian Shield (CS) that would dominate his research in the early and mid-1970's. Twenty years before, his graduate work on billion-year-old strata in Scotland established paleomagnetic methodologies applicable to sedimentary rocks generally. In 1958, he and Ronald Green presented an 'Upper Proterozoic' APW path from Australia as evidence for pre-Carboniferous drift relative to Europe and North America (the poles actually range in age from 1.2 to 2.7 Ga). His first published CS poles were obtained from the Franklin LIP of the Arctic platform and demonstrate igneous emplacement across the paleoequator. Characteristically, his 1971 poles are statistically indistinguishable from the most recent grand mean paleopole of 2009. His main focus, however, was on the question of Precambrian continental drift. He compared APW paths with respect to Laurentia with those obtained from other Precambrian shields, and he compared APW paths from different tectonic provinces within the CS. He was consistently antagonistic to the concept of a single long-lived Proterozoic supercontinent, but he was on less certain ground regarding motions within the CS due to inadequate geochronology. With Ron Emslie, he boldly proposed rapid convergence between parts of the Grenville Province and Interior Laurentia (IL) ~1.0 Ga. This was controversial given the uncertain ages of multiple magnetic components in high-grade metamorphic rocks. With John McGlynn and John Park, he developed a Paleoproterozoic APW path for the Slave Province from mafic dikes and red clastics, encompassing the time of consolidation of IL during 2.0-1.8 Ga orogenesis. Before 1980, he constructed Paleoproterozoic APW paths for IL as a whole, finding little evidence for significant internal displacement. He recognized that the Laurentian APW path describes a series of straight tracks linked by hairpins, the latter corresponding in age to

  7. Teacher’s Instructional Behaviour in Instructional Management at Elementary School Reviewed from Piaget’s Cognitive Development Theory

    Directory of Open Access Journals (Sweden)

    Eni Astuti Ni Putu

    2018-01-01

    Full Text Available This writing aimed at (1 describing the importance of teacher to review instructional management at elementary school based on Piaget’s cognitive development theory; and (2 describing teacher’s instructional behavior in managing instructional at elementary school reviewed from Piaget’s cognitive development theory. In general, Piaget’ cognitive development theory divides children’ cognitive development into four stages. In the elementary school ages of 7 to 11 or 12 years old, Piaget classified the cognitive development into concrete operational marked by the use of clear and logic rules. The children implement logic thinking on concrete object, yet abstract or hypothetical. Although the intelligence of this step has been advanced, the way of thinking of the children is still limited because still based on concrete object. Therefore, teacher should comprehend the importance of concrete operational instructional at elementary school so the children could maximally achieve the learning goal in accordance to their thinking level that they acquire. The suggestion that can be proposed is that the teacher should synergize the characteristics of elementary school students in concrete operational stage with the instructional readiness in the steps of planning, implementation and evaluation.

    Accumulating evidence suggests that assessment-informed personalized instruction, tailored to students' individual skills and abilities, is more effective than more one-size-fits-all approaches. In this study, we evaluate the efficacy of Individualizing Student Instruction in Mathematics (ISI-Math) compared to Reading (ISI-Reading) where classrooms were randomly assigned to ISI-Math or ISI-Reading. The literature on child characteristics X instruction or skill X treatment interaction effects point to the complexities of tailoring instruction for individual students who present with constellations of skills. Second graders received mathematics instruction in small flexible learning groups based on their assessed learning needs. Results of the study (n=32 teachers, 370 students) revealed significant treatment effects on standardized mathematics assessments. With effect sizes (d) of 0.41-0.60, we show that we can significantly improve 2nd graders' mathematics achievement, including for children living in poverty, by using assessment data to individualize the mathematics instruction they receive. The instructional regime, ISI-Math, was implemented by regular classroom teachers and it led to about a 4-month achievement advantage on standardized mathematics tests when compared to students in control classrooms. These results were realized within one school year. Moreover, treatment effects were the same regardless of school-level poverty and students' gender, initial mathematics or vocabulary scores.

    Franklin T. Thompson

    2014-02-01

    Full Text Available The reason why the Trayvon Martin murder trial and similar court cases create a philosophical rift in our nation is due in part to flaws in the delivery of multicultural education. Traditional multicultural instruction does not prepare citizens for the subtleties and complexities of race relations. This study investigates critical strategies and practices that address multicultural missing gaps. I also seek to fill a void in the literature created by a lack of student input regarding teaching strategies that encourage lifelong learning. Students (N = 337 enrolled at a Midwestern university were asked to rate the efficacy of selected instructional strategies. Utilizing a 9-point Likert-type scale, students gave themselves a personal growth rating of 7.15 (SD = 1.47. Variables important to predicting that growth (R2 = .56, p < .0005 were a six-factor variable known as a non-color-blind instructional approach (t = 10.509, p ≤ .0005, allowing students an opportunity to form their own opinions apart from the instructor (t = 4.797, p ≤ .0005, and a state law that mandated multicultural training (t = 3.234, p = .001. Results demonstrated that utilizing a 35% traditional and 65% critical pedagogy mixture when teaching multicultural education helped promote win/win scenarios for education candidates hoping to become difference makers.

    Directory of Open Access Journals (Sweden)

    Tatana M. Olson

    2002-10-01

    Full Text Available As the use of Web-based instruction increases in the educational and training domains, many people have recognized the importance of evaluating its effects on student outcomes such as learning, performance, and satisfaction. Often, these results are compared to those of conventional classroom instruction in order to determine which method is “better.” However, major differences in technology and presentation rather than instructional content can obscure the true relationship between Web-based instruction and these outcomes. Computer-based instruction (CBI, with more features similar to Web-based instruction, may be a more appropriate benchmark than conventional classroom instruction. Furthermore, there is little consensus as to what variables should be examined or what measures of learning are the most appropriate, making comparisons between studies difficult and inconclusive. In this article, we review the historical findings of CBI as an appropriate benchmark to Web-based instruction. In addition, we review 47 reports of evaluations of Web-based courses in higher education published between 1996 and 2002. A tabulation of the documented findings into eight characteristics is offered, along with our assessments of the experimental designs, effect sizes, and the degree to which the evaluations incorporated features unique to Web-based instruction.

  10. Influence of verbal instructions on effect-based action control.

    Science.gov (United States)

    Eder, Andreas B; Dignath, David

    2017-03-01

    According to ideomotor theory, people use bidirectional associations between movements and their effects for action selection and initiation. Our experiments examined how verbal instructions of action effects influence response selection without prior experience of action effects in a separate acquisition phase. Instructions for different groups of participants specified whether they should ignore, attend, learn, or intentionally produce acoustic effects produced by button presses. Results showed that explicit instructions of action-effect relations trigger effect-congruent action tendencies in the first trials following the instruction; in contrast, no evidence for effect-based action control was observed in these trials when instructions were to ignore or to attend to the action effects. These findings show that action-effect knowledge acquired through verbal instruction and direct experience is similarly effective for effect-based action control as long as the relation between the movement and the effect is clearly spelled out in the instruction.

  1. Attentional Focusing Instructions and Force Production

    Directory of Open Access Journals (Sweden)

    David C Marchant

    2011-01-01

    Full Text Available Research progress assessing the role of attentional focusing instructions on skill acquisition and performance has lead researchers to apply this approach to force production tasks. Initial converging evidence indicates that force production tasks are sensitive to verbal instruction; externally focused instructions (onto movement outcomes, or onto the object force is being exerted against are shown to be more beneficial than internally focused instructions (focusing attention onto the movements being executed. These benefits are observed for maximal and accurate force production, as well as the maintenance of force production in prolonged tasks. A range of mechanisms are identified supporting the proposal that an external focus promotes movement efficiency in line with energy and effort conservation. Future research is required to assess how this developing body of work interacts with the broader understanding of psychological and physiological factors implicated in the effective production, maintenance and limitation of maximal or sub-maximal forces.

  2. Ethics instruction in the dental hygiene curriculum.

    Science.gov (United States)

    Kacerik, Mark G; Prajer, Renee G; Conrad, Cynthia

    2006-01-01

    Dental hygiene ethics is an essential component of the dental hygiene curriculum. The accreditation standards for dental hygiene education state that graduates must be competent in applying ethical concepts to the provision and/or support of oral health care services. Although the standards for entry into the profession of dental hygiene emphasize the importance of ethical reasoning, there is little published research specific to ethics instruction in dental hygiene programs. The purpose of this study was to assess how ethics is taught in the dental hygiene curriculum. A 17-item survey was designed and distributed to 261 accredited dental hygiene programs in the United States for a response rate of 56% (N=147). The survey requested that participants provide information on teaching and evaluation methodologies, didactic and clinical hours of instruction, individuals responsible for providing instruction, and the degree of emphasis placed on ethics and integration of ethical reasoning within the dental hygiene curriculum. Results of the survey reflect that dental hygiene programs devote a mean of 20. hours to teaching dental hygiene ethics in the didactic component of the curriculum. With regard to the clinical component of the curriculum, 63% of respondents indicated that 10 or less hours are devoted to ethics instruction. These results show an increase in didactic hours of instruction from previous studies where the mean hours of instruction ranged from 7 to 11.7 hours. Results showed 64% of respondents offered a separate course in ethics; however, 82% of programs surveyed indicated that ethics was incorporated into one or more dental hygiene courses with 98% utilizing dental hygiene faculty to provide instruction. Most programs utilized a variety of instructional methods to teach ethics with the majority employing class discussion and lecture (99% and 97% respectively). The type of institution-technical college, community college, four-year university with a

  3. Resource Letter ALIP-1: Active-Learning Instruction in Physics

    Meltzer, David E.; Thornton, Ronald K.

    2012-06-01

    This Resource Letter provides a guide to the literature on research-based active-learning instruction in physics. These are instructional methods that are based on, assessed by, and validated through research on the teaching and learning of physics. They involve students in their own learning more deeply and more intensely than does traditional instruction, particularly during class time. The instructional methods and supporting body of research reviewed here offer potential for significantly improved learning in comparison to traditional lecture-based methods of college and university physics instruction. We begin with an introduction to the history of active learning in physics in the United States, and then discuss some methods for and outcomes of assessing pedagogical effectiveness. We enumerate and describe common characteristics of successful active-learning instructional strategies in physics. We then discuss a range of methods for introducing active-learning instruction in physics and provide references to those methods for which there is published documentation of student learning gains.

  4. Language used in interaction during developmental science instruction

    Science.gov (United States)

    Avenia-Tapper, Brianna

    The coordination of theory and evidence is an important part of scientific practice. Developmental approaches to instruction, which make the relationship between the abstract and the concrete a central focus of students' learning activity, provide educators with a unique opportunity to strengthen students' coordination of theory and evidence. Therefore, developmental approaches may be a useful instructional response to documented science achievement gaps for linguistically diverse students. However, if we are to leverage the potential of developmental instruction to improve the science achievement of linguistically diverse students, we need more information on the intersection of developmental science instruction and linguistically diverse learning contexts. This manuscript style dissertation uses discourse analysis to investigate the language used in interaction during developmental teaching-learning in three linguistically diverse third grade classrooms. The first manuscript asks how language was used to construct ascension from the abstract to the concrete. The second manuscript asks how students' non-English home languages were useful (or not) for meeting the learning goals of the developmental instructional program. The third manuscript asks how students' interlocutors may influence student choice to use an important discourse practice--justification--during the developmental teaching-learning activity. All three manuscripts report findings relevant to the instructional decisions that teachers need to make when implementing developmental instruction in linguistically diverse contexts.

  15. Instructional decision making of high school science teachers

    Science.gov (United States)

    Carver, Jeffrey S.

    The instructional decision-making processes of high school science teachers have not been well established in the literature. Several models for decision-making do exist in other teaching disciplines, business, computer game programming, nursing, and some fields of science. A model that incorporates differences in science teaching that is consistent with constructivist theory as opposed to conventional science teaching is useful in the current climate of standards-based instruction that includes an inquiry-based approach to teaching science. This study focuses on three aspects of the decision-making process. First, it defines what factors, both internal and external, influence high school science teacher decision-making. Second, those factors are analyzed further to determine what instructional decision-making processes are articulated or demonstrated by the participants. Third, by analyzing the types of decisions that are made in the classroom, the classroom learning environments established as a result of those instructional decisions are studied for similarities and differences between conventional and constructivist models. While the decision-making process for each of these teachers was not clearly articulated by the teachers themselves, the patterns that establish the process were clearly exhibited by the teachers. It was also clear that the classroom learning environments that were established were, at least in part, established as a result of the instructional decisions that were made in planning and implementation of instruction. Patterns of instructional decision-making were different for each teacher as a result of primary instructional goals that were different for each teacher. There were similarities between teachers who exhibited more constructivist epistemological tendencies as well as similarities between teachers who exhibited a more conventional epistemology. While the decisions that will result from these two camps may be different, the six step

    Kennedy, Michael J; Deshler, Donald D; Lloyd, John Wills

    2015-01-01

    The purpose of this experimental study is to investigate the effects of using content acquisition podcasts (CAPs), an example of instructional technology, to provide vocabulary instruction to adolescents with and without learning disabilities (LD). A total of 279 urban high school students, including 30 with LD in an area related to reading, were randomly assigned to one of four experimental conditions with instruction occurring at individual computer terminals over a 3-week period. Each of the four conditions contained different configurations of multimedia-based instruction and evidence-based vocabulary instruction. Dependent measures of vocabulary knowledge indicated that students with LD who received vocabulary instruction using CAPs through an explicit instructional methodology and the keyword mnemonic strategy significantly outperformed other students with LD who were taught using the same content, but with multimedia instruction that did not adhere to a specific theoretical design framework. Results for general education students mirrored those for students with LD. Students also completed a satisfaction measure following instruction with multimedia and expressed overall agreement that CAPs are useful for learning vocabulary terms. © Hammill Institute on Disabilities 2013.

    The aim of this study was to determine whether the optic nerve is affected by thyroid eye disease (TED) before the development of dysthyroid optic neuropathy with diffusion-tensor imaging (DTI). Twenty TED patients and 20 controls were included. The mean, axial, and radial diffusivities and fractional anisotropy (FA) value were measured at the optic nerves in DTI. Extraocular muscle diameters were measured on computed tomography. The diffusivities and FA of the optic nerves were compared between TED and controls and between active and inactive stages of TED. The correlations between these DTI parameters and the clinical features were determined. The mean, axial, and radial diffusivities were lower in TED compared with the controls (P optic nerve before dysthyroid optic neuropathy in TED. The FA, in particular, reflected TED activity and severity.

  7. Inquiry-Based Instruction and High Stakes Testing

    Science.gov (United States)

    Cothern, Rebecca L.

    Science education is a key to economic success for a country in terms of promoting advances in national industry and technology and maximizing competitive advantage in a global marketplace. The December 2010 Program for International Student Assessment (PISA) ranked the United States 23rd of 65 countries in science. That dismal standing in science proficiency impedes the ability of American school graduates to compete in the global market place. Furthermore, the implementation of high stakes testing in science mandated by the 2007 No Child Left Behind (NCLB) Act has created an additional need for educators to find effective science pedagogy. Research has shown that inquiry-based science instruction is one of the predominant science instructional methods. Inquiry-based instruction is a multifaceted teaching method with its theoretical foundation in constructivism. A correlational survey research design was used to determine the relationship between levels of inquiry-based science instruction and student performance on a standardized state science test. A self-report survey, using a Likert-type scale, was completed by 26 fifth grade teachers. Participants' responses were analyzed and grouped as high, medium, or low level inquiry instruction. The unit of analysis for the achievement variable was the student scale score average from the state science test. Spearman's Rho correlation data showed a positive relationship between the level of inquiry-based instruction and student achievement on the state assessment. The findings can assist teachers and administrators by providing additional research on the benefits of the inquiry-based instructional method. Implications for positive social change include increases in student proficiency and decision-making skills related to science policy issues which can help make them more competitive in the global marketplace.

    1985-01-01

    In this paper the role of instructional psychology in simulator design and use is discussed. It is suggested that research and development work has tended to focus upon the face validity of simulators rather than their instructional utility. Dimensions of simulation are reviewed as are the variety of uses to which a simulator may be put. The nature of instructional psychology is briefly described under the following headings: task analysis, the acquisition of knowledge and skill and theories of instruction. Attention is also given to the potential role of computer-based training and the topic of retention of training is introduced. (author)

  15. Short-term diffusive sampler for nitrogen dioxide monitoring in epidemiology

    International Nuclear Information System (INIS)

    Michaud, J.P.; Quackenboss, J.

    1991-01-01

    An automated timed exposure diffusive sampler (TEDS) for sampling nitrogen dioxide (NO 2 ) was developed for use in epidemiological studies. The TEDS sequentially exposes four passive sampling devices (PSD) by microprocessor controlled valves while a pump and air flow guide prevent sampler starvation. Two TEDS units and two portable, real-time NO 2 monitors were tested for accuracy, precision, sensitivity, and linearity of response. The accuracy of the TEDS was within 10 percent of the means of the measured values. The TEDS sensitivity was 20 to 30 ppb-hour for NO 2 . Co-location of the TEDS with a chemiluminescent NO x monitor (EPA reference method) showed a similar responses to ambient NO 2 . TEDS allows better time resolution than traditional diffusive samplers (i.e., Palmes tube) while sharing their ability to sample a variety of gases

    Science.gov (United States)

    Bonney, Dianna

    The purpose of this action research project was to determine the extent to which metacognitive instruction affected students' performance in the middle-grade science classroom. Conducted with four seventh grade science classes over a three-month time period, 105 students were engaged in 21 metacognitively enhanced lessons. Both quantitative and qualitative data sources were collected for this study and analyzed according to grounded theory methodology. Quantitative data came from the Jr. Metacognitive Awareness Inventory, administered as a pre-post test. Qualitative teacher-generated data was collected in a metacognitive observation protocol containing observations and reflections while student-generated data was gathered from reflective journal entries, modified rubrics, and checklists. Analysis of the data led to the assertions that metacognitive development occurred over time through systematic and varied implementation of explicit instruction. In addition, students perceived they learned best both when working collaboratively and when making multiple connections with content material. Implications for middle-grade teachers include the need for explicit instruction of metacognitive strategies, providing for instructional variation and student collaboration, and guiding students in making connections to prior learning.

    2007-01-01

    OBJECTIVE To develop a typology of after-hours care (AHC) instructions and to examine physician and practice characteristics associated with each type of instruction. DESIGN Cross-sectional telephone survey. Physicians’ offices were called during evenings and weekends to listen to their messages regarding AHC. All messages were categorized. Thematic analysis of a subset of messages was conducted to develop a typology of AHC instructions. Logistic regression analysis was used to identify associations between physician and practice characteristics and the instructions left for patients. SETTING Family practices in the greater Toronto area. PARTICIPANTS Stratified random sample of family physicians providing office-based primary care. MAIN OUTCOME MEASURES Form of response (eg, answering machine), content of message, and physician and practice characteristics. RESULTS Of 514 after-hours messages from family physicians’ offices, 421 were obtained from answering machines, 58 were obtained from answering services, 23 had no answer, 2 gave pager numbers, and 10 had other responses. Message content ranged from no AHC instructions to detailed advice; 54% of messages provided a single instruction, and the rest provided a combination of instructions. Content analysis identified 815 discrete instructions or types of response that were classified into 7 categories: 302 instructed patients to go to an emergency department; 122 provided direct contact with a physician; 115 told patients to go to a clinic; 94 left no directions; 76 suggested calling a housecall service; 45 suggested calling Telehealth; and 61 suggested other things. About 22% of messages only advised attending an emergency department, and 18% gave no advice at all. Physicians who were female, had Canadian certification in family medicine, held hospital privileges, or had attended a Canadian medical school were more likely to be directly available to their patients. CONCLUSION Important issues identified

  20. Gently dipping normal faults identified with Space Shuttle radar topography data in central Sulawesi, Indonesia, and some implications for fault mechanics

    Science.gov (United States)

    Spencer, J.E.

    2011-01-01

    Space-shuttle radar topography data from central Sulawesi, Indonesia, reveal two corrugated, domal landforms, covering hundreds to thousands of square kilometers, that are bounded to the north by an abrupt transition to typical hilly to mountainous topography. These domal landforms are readily interpreted as metamorphic core complexes, an interpretation consistent with a single previous field study, and the abrupt northward transition in topographic style is interpreted as marking the trace of two extensional detachment faults that are active or were recently active. Fault dip, as determined by the slope of exhumed fault footwalls, ranges from 4?? to 18??. Application of critical-taper theory to fault dip and hanging-wall surface slope, and to similar data from several other active or recently active core complexes, suggests a theoretical limit of three degrees for detachment-fault dip. This result appears to conflict with the dearth of seismological evidence for slip on faults dipping less than ~. 30??. The convex-upward form of the gently dipping fault footwalls, however, allows for greater fault dip at depths of earthquake initiation and dominant energy release. Thus, there may be no conflict between seismological and mapping studies for this class of faults. ?? 2011 Elsevier B.V.

  2. The Role of Grammar Instruction in Language Teaching

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    @@ The role of grammar instruction in foreign or second language acquisition is one of the most con troversial issues in foreign/second language teach ing and learning research. The advocators of gram mar instruction argue that grammar should be the core of language instruction and formal instruction enhances formal accuracy. On the other hand, crit ics naintain that the grammar knowledge has lim ited uses and may hinder the students from acquir ing the communicative competence and efficiency. Undoubtedly these two extreme theories often put teachers into a dilemma. What theory should they believe then? Do they accept the one and ignore the other?

  11. Development of fabrication method for thermal expansion difference irradiation temperature monitor

    International Nuclear Information System (INIS)

    Noguchi, Kouichi; Takatsudo, Hiroshi; Miyakawa, Shun-ichi; Kobori, Takahisa; Miyo, Toshimasa

    1998-03-01

    This report describes the development activities for the fabrication of the Thermal Expansion Difference irradiation temperature monitor (TED) at the Oarai Engineering Center (OEC)/PNC. TED is used for various irradiation tests in the experimental fast reactor JOYO. TED is the most accurate off-line temperature monitor used for irradiation examination. The TED is composed of a metallic sphere lid and either a stainless steel or nickel alloy container. Once the container is filled with sodium, the metallic sphere lid is sealed by using a resistance weld. This capsule is then loaded into a reactor. Once a TED is loaded into the JOYO reactor, the sodium inside the metallic container increases as a result of thermal expansion. The TED identifies the peak irradiation temperature of the reactor based on a formula correlating temperature to increment values. This formula is established specifically for the particular TED being used during a calibration process performed when the TED is fabricated. Initially the TED was developed by Argonne National Laboratory (ANL) in the United States, and was imported by PNC for use in the JOYO reactor. In 1992 PNC decided to fabricate TED domestically in order to ensure the stability of future supplies. Based on technical information provided by ANL, PNC began fabrication of a TED on an experimental basis. In addition, PNC endeavored to make the domestically produced TED more efficient. This involved improving the techniques used in the sodium filling and the metallic sphere welding processes. These quality control efforts led to PNC's development of processes enabling the capsules to be filled with sodium to nearly 100%. As a result, the accuracy of the temperature dispersion in the out-pile calibration test was improved from +/-10degC to +/-5degC. In 1996 the new domestically fabricated TED was attached to a JOYO irradiation rig. In March of 1997, irradiation of the rig was started on the 30th duty cycle operation, and should be

    The aim of this study was to investigate whether terrestrosin D (TED) inhibits the progression of castration-resistant prostate cancer and consider its mechanism. Cell cycle, mitochondrial membrane potential (ΔΨm) and apoptosis were determined by flow cytometry. Caspase-3 activity and vascular endothelial growth factor secretion were detected by a caspase-3 assay and human vascular endothelial growth factor kit, respectively. A PC-3 xenograft mouse model was used to evaluate the anticancer effect of TED in vivo. In vitro, TED strongly suppressed the growth of prostate cancer cells and endothelial cells in a dose-dependent manner. TED induced cell cycle arrest and apoptosis in PC-3 cells and human umbilical vascular endothelial cells (HUVECs). TED-induced apoptosis did not involve the caspase pathway. TED also decreased ΔΨm in PC-3 cells and HUVECs. In vivo, TED significantly suppressed tumor growth in nude mice bearing PC-3 cells, without any overt toxicity. Immunohistochemical analysis showed TED induced apoptotic cell death and inhibited angiogenesis in xenograft tumor cells. Cell cycle arrest and induction of apoptosis in cancer cells and endothelial cells might be plausible mechanisms of actions for the observed antitumor and antiangiogenic activities of TED. © 2014 S.

  16. Biased lineup instructions and face identification from video images.

    Science.gov (United States)

    Thompson, W Burt; Johnson, Jaime

    2008-01-01

    Previous eyewitness memory research has shown that biased lineup instructions reduce identification accuracy, primarily by increasing false-positive identifications in target-absent lineups. Because some attempts at identification do not rely on a witness's memory of the perpetrator but instead involve matching photos to images on surveillance video, the authors investigated the effects of biased instructions on identification accuracy in a matching task. In Experiment 1, biased instructions did not affect the overall accuracy of participants who used video images as an identification aid, but nearly all correct decisions occurred with target-present photo spreads. Both biased and unbiased instructions resulted in high false-positive rates. In Experiment 2, which focused on video-photo matching accuracy with target-absent photo spreads, unbiased instructions led to more correct responses (i.e., fewer false positives). These findings suggest that investigators should not relax precautions against biased instructions when people attempt to match photos to an unfamiliar person recorded on video.

    2015-04-01

    Full Text Available An experiment was conducted to test the effectiveness of brief instruction in information structuring (i.e., representing and integrating information for improving the coherence of probability judgments and binary choices among intelligence analysts. Forty-three analysts were presented with comparable sets of Bayesian judgment problems before and immediately after instruction. After instruction, analysts’ probability judgments were more coherent (i.e., more additive and compliant with Bayes theorem. Instruction also improved the coherence of binary choices regarding category membership: after instruction, subjects were more likely to invariably choose the category to which they assigned the higher probability of a target’s membership. The research provides a rare example of evidence-based validation of effectiveness in instruction to improve the statistical assessment skills of intelligence analysts. Such instruction could also be used to improve the assessment quality of other types of experts who are required to integrate statistical information or make probabilistic assessments.

    This research discusses the differentiated instruction, a mathematic learning which is as expected by the students in connection with the differentiated instruction itself, its implementation, and the students’ responses. This research employs a survey method which involves 62 students as the research respondents. The mathematics learning types required by the students and their responses to the differentiated instruction are examined through questionnaire and interview. The mathematics learning types in orderly required by the students, from the highest frequency cover the easily understood instructions, slowly/not rushing teaching, fun, not complicated, interspersed with humour, various question practices, not too serious, and conducive class atmosphere for the instructions. Implementing the differentiated instruction is not easy. The teacher should be able to constantly assess the students, s/he should have good knowledge of relevant materials and instructions, and properly prepare the instructions, although it is time-consuming. The differentiated instruction is implemented on the instructions of numerical pattern materials. The strategies implemented are flexible grouping, tiered assignment, and compacting. The students positively respond the differentiated learning instruction that they become more motivated and involved in the instruction.

    2017-12-01

    Gentle remediation options (GRO) are based on the combined use of plants, associated microorganisms and soil amendments, which can potentially restore soil functions and quality. We studied the effects of three GRO (aided-phytostabilisation, in situ stabilisation and phytoexclusion, and aided-phytoextraction) on the soil microbial biomass and respiration, the activities of hydrolase enzymes involved in the biogeochemical cycles of C, N, P, and S, and bacterial community structure of trace element contaminated soils (TECS) from six field trials across Europe. Community structure was studied using denaturing gradient gel electrophoresis (DGGE) fingerprinting of Bacteria, α- and β-Proteobacteria, Actinobacteria and Streptomycetaceae, and sequencing of DGGE bands characteristic of specific treatments. The number of copies of genes involved in ammonia oxidation and denitrification were determined by qPCR. Phytomanagement increased soil microbial biomass at three sites and respiration at the Biogeco site (France). Enzyme activities were consistently higher in treated soils compared to untreated soils at the Biogeco site. At this site, microbial biomass increased from 696 to 2352 mg ATP kg -1 soil, respiration increased from 7.4 to 40.1 mg C-CO 2 kg -1 soil d -1 , and enzyme activities were 2-11-fold higher in treated soils compared to untreated soil. Phytomanagement induced shifts in the bacterial community structure at both, the total community and functional group levels, and generally increased the number of copies of genes involved in the N cycle (nirK, nirS, nosZ, and amoA). The influence of the main soil physico-chemical properties and trace element availability were assessed and eventual site-specific effects elucidated. Overall, our results demonstrate that phytomanagement of TECS influences soil biological activity in the long term. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Instructor immediacy has been positively associated with many desirable academic outcomes including increased student learning. This study extends existing understanding of instructional immediacy behaviours in elearning by describing postgraduate nursing students' reflections on their own experience. An exploratory, descriptive survey design was used to collect qualitative data. Participants were asked what behaviours or activities help to create rapport or a positive interpersonal connection (immediacy) between students and their online teacher(s). Thematic analysis of the data revealed three main themes: acknowledging and affirming student's personal and professional responsibilities; providing clear and timely information; and utilising rich media. These findings give lecturers insight into instructional strategies they may adopt to increase immediacy in elearning and hence improve student learning outcomes.

    2015-01-01

    Having hit power limitations to even more aggressive out-of-order execution in processor cores, many architects in the past decade have turned to single-instruction-multiple-data (SIMD) execution to increase single-threaded performance. SIMD execution, or having a single instruction drive execution of an identical operation on multiple data items, was already well established as a technique to efficiently exploit data parallelism. Furthermore, support for it was already included in many commodity processors. However, in the past decade, SIMD execution has seen a dramatic increase in the set of

    Kambayashi, Shaw; Abe, Yasuaki

    1993-01-01

    As a first step to realize an autonomous mobile robot for plant maintenance, where the robot is capable to understand instructions written in natural languages, we have developed a prototype of instruction understanding system which makes the robot construct its motion sequences to approach instrumentations and inspect them from input sentences written in Japanese. In the prototype system, the instruction understanding and planning capabilities are integrated by an inference engine which consists of a cyclic operation of three processings, i.e., sensing, decision, and execution. Based on environmental data and current states of the robot, a proper process such as natural language processing is triggered by the decision part of the inference engine to accomplish the input instructions. The multiple- and dynamic-planning capabilities, which are necessary to cope with dynamic changes of environments surrounding the robot, are achieved by utilizing the cyclic inference engine together with a set of the inference packets which keep intermediate results of natural language processing and planning for respective input instructions.

  3. Alkem instruction: Legal relief of a Federal State against instructions under the Atomic Energy Act issued by the Federal Government

    International Nuclear Information System (INIS)

    Steinberg, R.

    1987-01-01

    The German Federal Minister for the Environment, Protection of Nature, and Reactor Safety instructed the Hesse State Minister for Economics and Technology to grant the applications filed by Alkem GmbH for a first partial permit of the construction and operation of a fuel element factory, and to grant it on the basis of a draft working document discussed between the two ministries. The new feature is the refusal of the Hesse State Minister to follow these instructions. This has given rise to a conflict between the State and Federal Governments. The article deals with one aspect of the multifaceted legal controversy, i.e., the question of the possibilities of legal relief open to a Federal State against an instruction under the Atomic Energy Act issued by the Federal Government. First, the rank of this instruction within the scope of administration on behalf of the Federal Government will be discussed. Next, the central problem of the preconditions under which an instruction may violate rights of a Federal State will be investigated. Finally, the possibilities of litigation will be briefly referred to. (orig./HP) [de

  4. Instructional control of reinforcement learning: a behavioral and neurocomputational investigation.

    Humans learn how to behave directly through environmental experience and indirectly through rules and instructions. Behavior analytic research has shown that instructions can control behavior, even when such behavior leads to sub-optimal outcomes (Hayes, S. (Ed.). 1989. Rule-governed behavior: cognition, contingencies, and instructional control. Plenum Press.). Here we examine the control of behavior through instructions in a reinforcement learning task known to depend on striatal dopaminergic function. Participants selected between probabilistically reinforced stimuli, and were (incorrectly) told that a specific stimulus had the highest (or lowest) reinforcement probability. Despite experience to the contrary, instructions drove choice behavior. We present neural network simulations that capture the interactions between instruction-driven and reinforcement-driven behavior via two potential neural circuits: one in which the striatum is inaccurately trained by instruction representations coming from prefrontal cortex/hippocampus (PFC/HC), and another in which the striatum learns the environmentally based reinforcement contingencies, but is "overridden" at decision output. Both models capture the core behavioral phenomena but, because they differ fundamentally on what is learned, make distinct predictions for subsequent behavioral and neuroimaging experiments. Finally, we attempt to distinguish between the proposed computational mechanisms governing instructed behavior by fitting a series of abstract "Q-learning" and Bayesian models to subject data. The best-fitting model supports one of the neural models, suggesting the existence of a "confirmation bias" in which the PFC/HC system trains the reinforcement system by amplifying outcomes that are consistent with instructions while diminishing inconsistent outcomes.

  5. Using Technology and Assessment to Personalize Instruction: Preventing Reading Problems.

    Children who fail to learn to read proficiently are at serious risk of referral to special education, grade retention, dropping out of high school, and entering the juvenile justice system. Accumulating research suggests that instruction regimes that rely on assessment to inform instruction are effective in improving the implementation of personalized instruction and, in turn, student learning. However, teachers find it difficult to interpret assessment results in a way that optimizes learning opportunities for all of the students in their classrooms. This article focuses on the use of language, decoding, and comprehension assessments to develop personalized plans of literacy instruction for students from kindergarten through third grade, and A2i technology designed to support teachers' use of assessment to guide instruction. Results of seven randomized controlled trials demonstrate that personalized literacy instruction is more effective than traditional instruction, and that sustained implementation of personalized literacy instruction first through third grade may prevent the development of serious reading problems. We found effect sizes from .2 to .4 per school year, which translates into about a 2-month advantage. These effects accumulated from first through third grade with a large effect size (d = .7) equivalent to a full grade-equivalent advantage on standardize tests of literacy. These results demonstrate the efficacy of technology-supported personalized data-driven literacy instruction to prevent serious reading difficulties. Implications for translational prevention research in education and healthcare are discussed.

    Virtual microscopy is being introduced in medical education as an approach for learning how to interpret information in microscopic specimens. It is, however, far from evident how to incorporate its use into existing teaching practice. The aim of the study was to explore the consequences of introducing virtual microscopy tasks into an undergraduate pathology course in an attempt to render the instruction more process-oriented. The research questions were: 1) How is virtual microscopy perceived by students? 2) Does work on virtual microscopy tasks contribute to improvement in performance in microscopic pathology in comparison with attending assistant-led demonstrations only? During a one-week period, an experimental group completed three sets of virtual microscopy homework assignments in addition to attending demonstrations. A control group attended the demonstrations only. Performance in microscopic pathology was measured by a pre-test and a post-test. Student perceptions of regular instruction and virtual microscopy were collected one month later by administering the Inventory of Intrinsic Motivation and open-ended questions. The students voiced an appreciation for virtual microscopy for the purposes of the course and for self-study. As for learning gains, the results indicated that learning was speeded up in a subgroup of students consisting of conscientious high achievers. The enriched instruction model may be suited as such for elective courses following the basic course. However, the instructional model needs further development to be suited for basic courses.

    Primary deficiency of complement C3 is rare and usually associated with increased susceptibility to bacterial infections. In this work, we investigated the molecular basis of complete C3 deficiency in a Brazilian 9-year old female patient with a family history of consanguinity. Hemolytic assays revealed complete lack of complement-mediated hemolytic activity in the patient's serum. While levels of the complement regulatory proteins Factor I, Factor H and Factor B were normal in the patient's and family members' sera, complement C3 levels were undetectable in the patient's serum and were reduced by at least 50% in the sera of the patient's parents and brother. Additionally, no C3 could be observed in the patient's plasma and cell culture supernatants by Western blot. We also observed that patient's skin fibroblasts stimulated with Escherichia coli LPS were unable to secrete C3, which might be accumulated within the cells before being intracellularly degraded. Sequencing analysis of the patient's C3 cDNA revealed a genetic mutation responsible for the complete skipping of exon 27, resulting in the loss of 99 nucleotides (3450-3549) located in the TED domain. Sequencing of the intronic region between the exons 26 and 27 of the C3 gene (nucleotides 6690313-6690961) showed a nucleotide exchange (T→C) at position 6690626 located in a splicing donor site, resulting in the complete skipping of exon 27 in the C3 mRNA.

  15. The equivalence of learning paths in early science instruction: effect of direct instruction and discovery learning.

    Klahr, David; Nigam, Milena

    2004-10-01

    In a study with 112 third- and fourth-grade children, we measured the relative effectiveness of discovery learning and direct instruction at two points in the learning process: (a) during the initial acquisition of the basic cognitive objective (a procedure for designing and interpreting simple, unconfounded experiments) and (b) during the subsequent transfer and application of this basic skill to more diffuse and authentic reasoning associated with the evaluation of science-fair posters. We found not only that many more children learned from direct instruction than from discovery learning, but also that when asked to make broader, richer scientific judgments, the many children who learned about experimental design from direct instruction performed as well as those few children who discovered the method on their own. These results challenge predictions derived from the presumed superiority of discovery approaches in teaching young children basic procedures for early scientific investigations.

    2012-01-01

    The present study replicates and extends previous research on the use of video modeling (VM) with voiceover instruction to train staff to implement discrete-trial instruction (DTI). After staff trainees reached the mastery criterion when teaching an adult confederate with VM, they taught a child with a developmental disability using DTI. The results showed that the staff trainees' accurate implementation of DTI remained high, and both child participants acquired new skills. These findings provide additional support that VM may be an effective method to train staff members to conduct DTI.
