  5. Forensic Science Curriculum for High School Students

    Burgess, Christiana J.

    Over the last several decades, forensic science---the application of science to civil and criminal legal matters---has become of increasing popularity with the public. The range of disciplines within the field is immense, offering individuals the potential for a unique career, regardless of their specific interests or expertise. In response to this growth, many organizations, both public and private, have recognized the need to create forensic science programs that strive to maintain and enhance the quality of forensic science education. Unfortunately, most of the emphasis placed on developing these materials relates to post-secondary education, and creates a significant lack of forensic science educational materials available in the U.S., especially in Oklahoma. The purpose of this project was to create a high school curriculum that provides the foundation for building a broad, yet comprehensive, overview of the field of forensic science and its associated disciplines. The overall goal was to create and provide course materials to high school teachers in order to increase their knowledge of forensic science such that they are able to teach its disciplines effectively and with accuracy. The Forensic Science Curriculum for High School Students includes sample lesson plans, PowerPoint presentations, and lab activities with step-by-step instructions.

  8. Improving Family Meetings in Intensive Care Units: A Quality Improvement Curriculum.

    Gruenewald, David A; Gabriel, Michelle; Rizzo, Dorothy; Luhrs, Carol A


    Family meetings in the intensive care unit are associated with beneficial outcomes for patients, their families, and health care systems, yet these meetings often do not occur in a timely, effective, reliable way. The Department of Veterans Affairs Comprehensive End-of-Life Care Implementation Center sponsored a national initiative to improve family meetings in Veterans Affairs intensive care units across the United States. Process measures of success for the initiative were identified, including development of a curriculum to support facility-based quality improvement projects to implement high-quality family meetings. Identified curriculum requirements included suitability for distance learning and applicability to many clinical intensive care units. Curriculum modules were cross-mapped to the "Plan-Do-Study-Act" model to aid in planning quality improvement projects. A questionnaire was e-mailed to users to evaluate the curriculum's effectiveness. Users rated the curriculum's effectiveness in supporting and achieving aims of the initiative as 3.6 on a scale of 0 (not effective) to 4 (very effective). Users adapted the curriculum to meet local needs. The number of users increased from 6 to 17 quality improvement teams in 2 years. All but 3 teams progressed to implementation of an action plan. Users were satisfied with the effectiveness and adaptability of a family-meeting quality improvement curriculum to support implementation of a quality improvement project in Veterans Affairs intensive care units. This tool may be useful in facilitating projects to improve the quality of family meetings in other intensive care units. ©2017 American Association of Critical-Care Nurses.

  10. Effectiveness of a quality improvement curriculum for medical students

    Kimberly M. Tartaglia


    Full Text Available Introduction: As health systems find ways to improve quality of care, medical training programs are finding opportunities to prepare learners on principles of quality improvement (QI. The impact of QI curricula for medical students as measured by student learning is not well delineated. The aim of this study is to evaluate the effectiveness of a QI curriculum for senior medical students as measured by student knowledge and skills. Methods: This study was an observational study that involved a self-assessment and post-test Quality Improvement Knowledge Application Tool (QIKAT for intervention and control students. A QI curriculum consisting of online modules, live discussions, independent readings and reflective writing, and participation in a mentored QI project was offered to fourth-year medical students completing an honor's elective (intervention group. Senior medical students who received the standard QI curriculum only were recruited as controls. Results: A total of 22 intervention students and 12 control students completed the self-assessment and QIKAT. At baseline, there was no difference between groups in self-reported prior exposure to QI principles. Students in the intervention group reported more comfort with their skills in QI overall and in 9 of the 12 domains (p<0.05. Additionally, intervention students performed better in each of the three case scenarios (p<0.01. Discussion: A brief QI curriculum for senior medical students results in improved comfort and knowledge with QI principles. The strengths of our curriculum include effective use of classroom time and faculty mentorship with reliance on pre-existing online modules and written resources. Additionally, the curriculum is easily expandable to larger groups of students and transferable to other institutions.

  13. Preparing Future Leaders: An Integrated Quality Improvement Residency Curriculum.

    Potts, Stacy; Shields, Sara; Upshur, Carole


    The Accreditation Council for Graduate Medical Education (ACGME) has recognized the importance of quality improvement (QI) training and requires that accredited residencies in all specialties demonstrate that residents are "integrated and actively participate in interdisciplinary clinical quality improvement and patient safety activities." However, competing demands in residency training may make this difficult to accomplish. The study's objective is to develop and evaluate a longitudinal curriculum that meets the ACGME requirement for QI and patient safety training and links to patient-centered medical home (PCMH) practices. Residents in the Worcester Family Medicine Residency (WFMR) participated in a faculty-developed quality improvement curriculum that included web-based tutorials, quality improvement projects, and small-group sessions across all 3 years of residency. They completed self-evaluations of knowledge and use of curricular activities annually and at graduation, and comparisons were made between two graduating classes, as well as comparison of end of PGY2 to end of PGY3 for one class. Graduating residents who completed the full 3 years of the curriculum rated themselves as significantly more skilled in nine of 15 areas assessed at end of residency compared to after PGY2 and reported confidence in providing future leadership in a focus group. Five areas were also rated significantly higher than prior-year residents. Involving family medicine residents in a longitudinal curriculum with hands-on practice in implementing QI, patient safety, and chronic illness management activities that are inclusive of PCMH goals increased their self-perceived skills and leadership ability to implement these new and emerging evidence-based practices in primary care.

    Robi Kroflič


    Full Text Available Modern curriculum theories emphasize that if we understand the curriculum as a real core substance of education. We have to bear in mind, when planning the curriculum, the whole multitude of factors (curricula which have an influence on the educational impact. In the field of andragogy, we especially have to consider educational needs, and linking the strategies of instruction with those of learning. The best way of realizing this principle is the open strategy of planning the national curriculum and process-developmental strategy of planning with the microandragogic situation. This planning strategy is S1m1lar to the system-integration strategy and Jarvis's model of negotiated curriculum, which derive from the basic andragogic principle: that the interests and capacities of adults for education increase if we enable them to cooperate in the planning and production of the curriculum.

  20. Postgraduate Education in Quality Improvement Methods: Initial Results of the Fellows' Applied Quality Training (FAQT) Curriculum.

    Winchester, David E; Burkart, Thomas A; Choi, Calvin Y; McKillop, Matthew S; Beyth, Rebecca J; Dahm, Phillipp


    Training in quality improvement (QI) is a pillar of the next accreditation system of the Accreditation Committee on Graduate Medical Education and a growing expectation of physicians for maintenance of certification. Despite this, many postgraduate medical trainees are not receiving training in QI methods. We created the Fellows Applied Quality Training (FAQT) curriculum for cardiology fellows using both didactic and applied components with the goal of increasing confidence to participate in future QI projects. Fellows completed didactic training from the Institute for Healthcare Improvement's Open School and then designed and completed a project to improve quality of care or patient safety. Self-assessments were completed by the fellows before, during, and after the first year of the curriculum. The primary outcome for our curriculum was the median score reported by the fellows regarding their self-confidence to complete QI activities. Self-assessments were completed by 23 fellows. The majority of fellows (15 of 23, 65.2%) reported no prior formal QI training. Median score on baseline self-assessment was 3.0 (range, 1.85-4), which was significantly increased to 3.27 (range, 2.23-4; P = 0.004) on the final assessment. The distribution of scores reported by the fellows indicates that 30% were slightly confident at conducting QI activities on their own, which was reduced to 5% after completing the FAQT curriculum. An interim assessment was conducted after the fellows completed didactic training only; median scores were not different from the baseline (mean, 3.0; P = 0.51). After completion of the FAQT, cardiology fellows reported higher self-confidence to complete QI activities. The increase in self-confidence seemed to be limited to the applied component of the curriculum, with no significant change after the didactic component.

  1. Examining the role of implementation quality in school-based prevention using the PATHS curriculum. Promoting Alternative THinking Skills Curriculum.

    Kam, Chi-Ming; Greenberg, Mark T; Walls, Carla T


    In order for empirically validated school-based prevention programs to "go to scale," it is important to understand the processes underlying program dissemination. Data collected in effectiveness trials, especially those measuring the quality of program implementation and administrative support, are valuable in explicating important factors influencing implementation. This study describes findings regarding quality of implementation in a recent effectiveness trial conducted in a high-risk, American urban community. This delinquency prevention trial is a locally owned intervention, which used the Promoting Alternative THinking Skills Curriculum as its major program component. The intervention involved 350 first graders in 6 inner-city public schools. Three schools implemented the intervention and the other 3 were comparison schools from the same school district. Although intervention effects were not found for all the intervention schools, the intervention was effective in improving children's emotional competence and reducing their aggression in schools which effectively supported the intervention. This study, utilizing data from the 3 intervention schools (13 classrooms and 164 students), suggested that 2 factors contributed to the success of the intervention: (a) adequate support from school principals and (b) high degree of classroom implementation by teachers. These findings are discussed in light of the theory-driven models in program evaluation that emphasized the importance of the multiple factors influencing the implementation of school-based interventions.

  2. Quality of faculty, students, curriculum and resources for nursing doctoral education in Korea: a focus group study.

    Kim, Mi Ja; Lee, Hyeonkyeong; Kim, Hyun Kyung; Ahn, Yang-Heui; Kim, Euisook; Yun, Soon-Nyoung; Lee, Kwang-Ja


    The rapidly increasing number of nursing doctoral programs has caused concern about the quality of nursing doctoral education, including in Korea. To describe the perceived quality of Korean nursing doctoral education in faculty, student, curriculum and resources. Focus group. Fourteen Korean nursing doctoral programs that are research focused and include coursework. Four groups of deans, faculty, students and graduates; students completed three semesters of doctoral program; and graduates completed doctoral programs within the most recent 3 years. Focus groups examined the strengths and weaknesses of faculty, students, curriculum, and resources. Faculty strengths were universities' recognition of faculty research/scholarship and the ability of faculty to attract extramural funding. Faculty weaknesses were aging faculty; high faculty workload; insufficient number of faculty; and teaching without expertise in nursing theories. Student strengths were diverse student backgrounds; multidisciplinary dissertation committee members, and opportunities to socialize with peers and graduates/faculty. Students' weaknesses were overproduction of PhDs with low academic quality; a lower number and quality of doctoral applicants; and lack of full-time students. Curriculum strengths were focusing on specific research areas; emphasis on research ethics; and multidisciplinary courses. Curriculum weaknesses were insufficient time for curriculum development; inadequate courses for core research competencies; and a lack of linkage between theory and practice. Resources strengths were inter-institutional courses with credit transfer. Weaknesses were diminished university financial support for graduate students and limited access to school facilities. Variations in participant groups (providers [deans and faculty] vs. receivers [students and graduates]) and geographical location (capital city vs. regional) were noted on all the four components. The quality characteristics of faculty

    Ogrinc, Greg; Cohen, Emily S; van Aalst, Robertus; Harwood, Beth; Ercolano, Ellyn; Baum, Karyn D; Pattison, Adam J; Jones, Anne C; Davies, Louise; West, Al


    Integrating teaching and hands-on experience in quality improvement (QI) may increase the learning and the impact of resident QI work. We sought to determine the clinical and educational impact of an integrated QI curriculum. This clustered, randomized trial with early and late intervention groups used mixed methods evaluation. For almost 2 years, internal medicine residents from Dartmouth-Hitchcock Medical Center on the inpatient teams at the White River Junction VA participated in the QI curriculum. QI project effectiveness was assessed using statistical process control. Learning outcomes were assessed with the Quality Improvement Knowledge Application Tool-Revised (QIKAT-R) and through self-efficacy, interprofessional care attitudes, and satisfaction of learners. Free text responses by residents and a focus group of nurses who worked with the residents provided information about the acceptability of the intervention. The QI projects improved many clinical processes and outcomes, but not all led to improvements. Educational outcome response rates were 65% (68 of 105) at baseline, 50% (18 of 36) for the early intervention group at midpoint, 67% (24 of 36) for the control group at midpoint, and 53% (42 of 80) for the late intervention group. Composite QIKAT-R scores (range, 0-27) increased from 13.3 at baseline to 15.3 at end point ( P  < .01), as did the self-efficacy composite score ( P  < .05). Satisfaction with the curriculum was rated highly by all participants. Learning and participating in hands-on QI can be integrated into the usual inpatient work of resident physicians.

  13. The Global Systems Science High School Curriculum

    Gould, A. D.; Sneider, C.; Farmer, E.; Erickson, J.


    Global Systems Science (GSS), a high school integrated interdisciplinary science project based at Lawrence Hall of Science at UC Berkeley, began in the early 1990s as a single book "Planet at Risk" which was only about climate change. Federal grants enabled the project to enlist about 150 teachers to field test materials in their classes and then meeting in summer institutes to share results and effect changes. The result was a series of smaller modules dealing not only with climate change, but other related topics including energy flow, energy use, ozone, loss of biodiversity, and ecosystem change. Other relevant societal issues have also been incorporated including economics, psychology and sociology. The course has many investigations/activities for student to pursue, interviews with scientists working in specific areas of research, and historical contexts. The interconnectedness of a myriad of small and large systems became an overarching theme of the resulting course materials which are now available to teachers for free online at

  14. A case study of translating ACGME practice-based learning and improvement requirements into reality: systems quality improvement projects as the key component to a comprehensive curriculum.

    Tomolo, A M; Lawrence, R H; Aron, D C


    In 2002, the Accreditation Council for Graduate Medical Education (ACGME) introduced a new requirement: residents must demonstrate competency in Practice-Based Learning and Improvement (PBLI). Training in this domain is still not consistently integrated into programmes, with few, if any, adequately going beyond knowledge of basic content and addressing all components of the requirement. To summarise the implementation of a PBLI curriculum designed to address all components of the requirement and to evaluate the impact on the practice system. A case-study approach was used for identifying and evaluating the steps for delivering the curriculum, along with the Model for Improvement's successive Plan-Do-Study-Act (PDSA) cycles (July 2004-May 2006). Notes from curriculum development meetings, notes and presentation slides made by teams about their projects, resident curriculum exit evaluations curriculum and interviews. Residents reported high levels of comfort by applying PBLI-related knowledge and skills and that the curriculum improved their ability to do various PBLI tasks. The involvement of multiple stakeholders increased. Twelve of the 15 teams' suggestions with practical systems-relevant outcomes were implemented and sustained beyond residents' project periods. While using the traditional PDSA cycles was helpful, there were limitations. A PBLI curriculum that is centred around practice-based quality improvement projects can fulfil the objectives of this ACGME competency while accomplishing sustained outcomes in quality improvement. A comprehensive curriculum is an investment but offers organisational rewards. We propose a more realistic and informative representation of rapid PDSA cycle changes.

  15. Physics teachers' perspectives on High School national curriculum policies

    Gleice Ferraz


    Full Text Available This study aimed to identify, in the context of an activity developed in online course for continuing education and from the theoretical approach of Mikhail Bakhtin, the discursive appropriation of PCNEM by high school physics teachers who work in different regional realities. The analysis indicated a positive perspective by teachers related to PCNEM, in addition to full accordance with the main path indicated by the legislation: the contextualized teaching. Despite the differences between educational regions we could not identify explicit signs of how these differences impacted the appropriation of terms found in PCNEM. The silence of teachers in relation to non-methodological aspects of physics teaching shapes their perspectives and also emphasizes the concern for didactic transposition of the content required by the curriculum, leaving out the question of why we have this curriculum and not other.

  18. Impact of a competency based curriculum on quality improvement among internal medicine residents.

    Fok, Mark C; Wong, Roger Y


    Teaching quality improvement (QI) principles during residency is an important component of promoting patient safety and improving quality of care. The literature on QI curricula for internal medicine residents is limited. We sought to evaluate the impact of a competency based curriculum on QI among internal medicine residents. This was a prospective, cohort study over four years (2007-2011) using pre-post curriculum comparison design in an internal medicine residency program in Canada. Overall 175 post-graduate year one internal medicine residents participated. A two-phase, competency based curriculum on QI was developed with didactic workshops and longitudinal, team-based QI projects. The main outcome measures included self-assessment, objective assessment using the Quality Improvement Knowledge Assessment Tool (QIKAT) scores to assess QI knowledge, and performance-based assessment via presentation of longitudinal QI projects. Overall 175 residents participated, with a response rate of 160/175 (91%) post-curriculum and 114/175 (65%) after conducting their longitudinal QI project. Residents' self-reported confidence in making changes to improve health increased and was sustained at twelve months post-curriculum. Self-assessment scores of QI skills improved significantly from pre-curriculum (53.4 to 69.2 percent post-curriculum [p-value 0.002]) and scores were sustained at twelve months after conducting their longitudinal QI projects (53.4 to 72.2 percent [p-value 0.005]). Objective scores using the QIKAT increased post-curriculum from 8.3 to 10.1 out of 15 (p-value for difference value for difference from pre-curriculum based assessment occurred via presentation of all projects at the annual QI Project Podium Presentation Day. The competency based curriculum on QI improved residents' QI knowledge and skills during residency training. Importantly, residents perceived that their QI knowledge improved after the curriculum and this also correlated to improved QIKAT

  19. Pediatrics Residents' Confidence and Performance Following a Longitudinal Quality Improvement Curriculum.

    Courtlandt, Cheryl; Noonan, Laura; Koricke, Maureen Walsh; Zeskind, Philip Sanford; Mabus, Sarah; Feld, Leonard


    Quality improvement (QI) training is an integral part of residents' education. Understanding the educational value of a QI curriculum facilitates understanding of its impact. The purpose of this study was to evaluate the effects of a longitudinal QI curriculum on pediatrics residents' confidence and competence in the acquisition and application of QI knowledge and skills. Three successive cohorts of pediatrics residents (N = 36) participated in a longitudinal curriculum designed to increase resident confidence in QI knowledge and skills. Key components were a succession of progressive experiential projects, QI coaching, and resident team membership culminating in leadership of the project. Residents completed precurricular and postcurricular surveys and demonstrated QI competence by performance on the pediatric QI assessment scenario. Residents participating in the Center for Advancing Pediatric Excellence QI curriculum showed significant increases in pre-post measures of confidence in QI knowledge and skills. Coaching and team leadership were ranked by resident participants as having the most educational value among curriculum components. A pediatric QI assessment scenario, which correlated with resident-perceived confidence in acquisition of QI skills but not QI knowledge, is a tool available to test pediatrics residents' QI knowledge. A 3-year longitudinal, multimodal, experiential QI curriculum increased pediatrics residents' confidence in QI knowledge and skills, was feasible with faculty support, and was well-accepted by residents.

The number of 12- to 17-year olds abusing controlled prescription drugs increased an alarming 212 percent between 1992 and 2003. For many youths, substance abuse precedes academic and health problems including lower grades, higher truancy, drop out decisions, delayed or damaged physical, cognitive, and emotional development, or a variety of other costly consequences. For thirty years the Narconon program has worked with schools and community groups providing single educational modules aimed at supplementing existing classroom-based prevention activities. In 2004, Narconon International developed a multi-module, universal prevention curriculum for high school ages based on drug abuse etiology, program quality management data, prevention theory and best practices. We review the curriculum and its rationale and test its ability to change drug use behavior, perceptions of risk/benefits, and general knowledge. Methods After informed parental consent, approximately 1000 Oklahoma and Hawai'i high school students completed a modified Center for Substance Abuse Prevention (CSAP Participant Outcome Measures for Discretionary Programs survey at three testing points: baseline, one month later, and six month follow-up. Schools assigned to experimental conditions scheduled the Narconon curriculum between the baseline and one-month follow-up test; schools in control conditions received drug education after the six-month follow-up. Student responses were analyzed controlling for baseline differences using analysis of covariance. Results At six month follow-up, youths who received the Narconon drug education curriculum showed reduced drug use compared with controls across all drug categories tested. The strongest effects were seen in all tobacco products and cigarette frequency followed by marijuana. There were also significant

    Full Text Available Abstract: This study is a part of a bigger study investigating teachers’ personal theories (beliefs regarding English teaching and learning. Involving forty-two English teachers of fifteen Junior High Schools in the city of Sukabumi, West Java, this cross-sectional survey study used data gained from an open-ended questionnaire. A total of 3696 raw data items were gathered and analyzed both qualitatively and quantitatively. Relevant findings regarding the implementation of the curriculum in the daily process of English teaching and learning show that there are gaps between the mandated curriculum as stipulated by the government and the implemented curriculum at the classroom level. This departure from the mandated curriculum, in turn, diverts the course of curriculum implementation and leads to a level of accomplishment of the main goals of the English teaching and learning, which is different from what is stated in the mandated curriculum.

  9. Implementing a Course Review Process for a Continuous Quality Improvement Model for a Medical School Curriculum.

    Ward, Cassandra S; Andrade, Amy; Walker-Winfree, Lena


    In 1901, Abraham Flexner, a research scholar at the Carnegie Foundation for the Advancement of Teaching, visited 155 medical schools in the United States and Canada to assess medical education. Flexner's recommendations became the foundation for the Liaison Committee on Medical Education accreditation, a voluntary, peer-reviewed quality assurance process to determine whether a medical education program meets established standards. The Meharry Medical College School of Medicine, a historically Black college/university (HBCU) established the Office of Curriculum Evaluation and Effectiveness in 2013 to ensure the consistent monitoring of the medical education program's compliance with accreditation standards. The motto and logo, LCME 24/7, highlight the school's emphasis on meeting accreditation standards. The school uses the 1994 Plan-Do-Study-Act Cycle for Learning and Improvement for continuous review of course content, outcomes, and evaluations. This process identifies strengths, challenges, and opportunities for innovative steps for continuous quality improvements to the curriculum.

    Full Text Available Objective: The purpose of this study was to determine the impact of a revised curriculum on medical student academic motivation, burnout, and quality of life. Methods: This cross-sectional comparative study involved 2 medical school cohorts of second year and fourth year medical students at The University of Auckland: a cohort under a traditional curriculum (n = 437 and a cohort under a revised curriculum (n = 446. Participants completed self-reported questionnaires measuring academic motivation, burnout, and quality of life. Two multivariate analyses of covariance (MANCOVAs were conducted. Results: The response rate was 48%. No statistically significant differences were found between curriculum cohorts for mean scores of academic motivation, personal burnout, and quality of life. However, differences were found when comparing preclinical medical students and students in their clinical years of training. In comparison with Year 2 medical students, the MANCOVA for Year 4 students showed a significant main effect for the revised curriculum with respect to both physical and environmental quality of life. Conclusions: A revised medical curriculum had a differential effect on quality of life for Year 4 students in the latter years of medical school who are based in a clinical learning environment.

  16. Preparing skilled labor in industry through production-based curriculum approach in vocational high school



    Vocational high school (Sekolah Menengah Kejuruan / SMK) aims to prepare mid-level skilled labors to work in the industry and are able to create self-employment opportunities. For those reasons, the curriculum in SMK should be based on meeting the needs of the industries and is able to prepare learners to master the competence in accordance with the skills program of their choice. Production based curriculum is the curriculum which the learning process is designed together with the production process or using production process as a learning medium. This approach with the primary intention to introduce students with the real working environment and not merely simulations. In the production-based curriculum implementation model, students are directly involved in the industry through the implementation of industrial working practices, do work on production units in school, and do practical work in school by doing the job as done in the industry by using industry standards machines.

  17. Combining clinical microsystems and an experiential quality improvement curriculum to improve residency education in internal medicine.

    Tess, Anjala V; Yang, Julius J; Smith, C Christopher; Fawcett, Caitlin M; Bates, Carol K; Reynolds, Eileen E


    Beth Israel Deaconess Medical Center's internal medicine residency program was admitted to the new Education Innovation Project accreditation pathway of the Accreditation Council of Graduate Medical Education to begin in July 2006. The authors restructured the inpatient medical service to create clinical microsystems in which residents practice throughout residency. Program leadership then mandated an active curriculum in quality improvement based in those microsystems. To provide the experience to every graduating resident, a core faculty in patient safety was trained in the basics of quality improvement. The authors hypothesized that such changes would increase the number of residents participating in quality improvement projects, improve house officer engagement in quality improvement work, enhance the culture of safety the residents perceive in their training environment, improve work flow on the general medicine ward rotations, and improve the overall educational experience for the residents on ward rotations.The authors describe the first 18 months of the intervention (July 2006 to January 2008). The authors assessed attitudes and the educational experience with surveys and evaluation forms. After the intervention, the authors documented residents' participation in projects that overlapped with hospital priorities. More residents reported roles in designing and implementing quality improvement changes. Residents also noted greater satisfaction with the quality of care they deliver. Fewer residents agreed or strongly agreed that the new admitting system interfered with communication. Ongoing residency program assessment showed an improved perception of workload, and educational ratings of rotations improved. The changes required few resources and can be transported to other settings.

  18. Dating methods enter high-school physics curriculum

    Beck, L.


    The new curriculum of physics of the upper forms in French grammar schools includes a part dedicated to ''nuclear transformations''. One of the applications most often considered in manuals is isotopic dating and generally several methods are explained to pupils: carbon 14 dating, potassium-argon dating (used for dating ancient lava layers) and uranium-thorium dating (used for dating corals). The author reviews with a critical eye the content of manuals and laments through concrete examples the lack of exactness and accuracy of some presentations. (A.C.)

  19. Biology technology, and innovation in high school curriculum

    Antonio Carlos Rodrigues de Amorim


    Full Text Available Based on frameworks that propose the contextualization of science education centered in the science/technology/ society relationships, and on the belief that the teacher has a fundamental role on the curriculum innovation processes, this paper describes and analyses different elements of the pedagogical practice of teachers of the city of Campinas/SP, in the perspective of outlining an overview regarding the already existing biology and technology relationship. It focuses in a detailed way the conceptions of the relationships between biology and technology present in the instructional materials used or produced by teachers, describing and discussing the wide range spectrum of identified possibilities. It also emphasizes the approaches to biology and technology relationships identified by interviewing the teachers, being them similar or not to those found in the instructional materials. Indicators of the existence of a problematic theory and practice association, in which the theoretical elements (science are hierarchically superior to the practical elements (technology, were detected. This kind of association should constitute a focus of attention in the construction of innovative proposals for the biology curriculum, since science classroom discussions regarding technology – in their ethical, aesthetical, epistemological, and marketing aspects – represent an important path to dimension the biological knowledge in the capitalist contemporary society.

  20. High-Value Consults: A Curriculum to Promote Point-of-Care, Evidence-Based Recommendations.

    Nandiwada, Deepa Rani; Kohli, Amar; McNamara, Megan; Smith, Kenneth J; Zimmer, Shanta; McNeil, Melissa; Spagnoletti, Carla; Rubio, Doris; Berlacher, Kathryn


    In an era when value-based care is paramount, teaching trainees to explicitly communicate the evidence behind recommendations fosters high-value care (HVC) in the consultation process. To implement an HVC consult curriculum highlighting the need for clear consult questions, evidence-based recommendations to improve consult teaching, clinical decision-making, and the educational value of consults. A pilot curriculum was implemented for residents on cardiology consult electives utilizing faculty and fellows as evidence-based medicine (EBM) coaches. The curriculum included an online module, an EBM teaching point template, EBM presentations on rounds, and "coach" feedback on notes. A total of 15 residents and 4 fellows on cardiology consults participated, and 87% (13 of 15) of residents on consults felt the curriculum was educationally valuable. A total of 80% (72 of 90) of residents on general medicine rotations responded to the survey, and 25 of 72 residents (35%) had a consult with the EBM template. General medicine teams felt the EBM teaching points affected clinical decision-making (48%, 12 of 25) and favored dissemination of the curriculum (90%, 72 of 80). Checklist-guided chart review showed a 22% improvement in evidence-based summaries behind recommendations (7 of 36 precurriculum to 70 of 146 charts postcurriculum, P  = .015). The HVC consult curriculum during a cardiology elective was perceived by residents to influence clinical decision-making and evidence-based recommendations, and was found to be educationally valuable on both parties in the consult process.

Based on the results of this study, it is recommended that lecturers’ ability to implement the Competency and Conservation Based Curriculum needs to be improved. Workshops and training should be given to lecturers in order to help them to create learning apparatus such as syllabus, lesson plans and teaching materials, as well as the evaluation of Competency and Conservation Based Curriculum.

  2. SU-F-E-08: Medical Physics as a Teaching Tool for High School Science Curriculum

    Buckley, L [The Ottawa Hospital Cancer Ctr., Ottawa, ON (Canada)


    Purpose: Delivering high school science curriculum in a timely manner and in way that is accessible to all students is a challenge for teachers. Although many high schools offer career workshops, these are typically directed at senior students and do not relate directly to details of the curriculum. The objective of this initiative was to create a series of lectures that use medical physics to relate many aspects of the high school science curriculum to tangible clinical applications and to introduce students to alternate pathways into a career in health sciences. Methods: A series of lectures has been developed based on the Ontario High School Science Curriculum. Each lecture uses a career in radiotherapy medical physics as the framework for discussion of topics specific to the high school course being addressed. Results: At present, these lectures have been delivered in five area high schools to students ranging from sophomores to seniors. Survey documents are given to the students before and after the lecture to assess their awareness of careers in health care, applications of physics and their general interest in the subject areas. As expected, students have limited up front awareness of the wide variety of health related career paths. The idea of combining a career lecture with topics specific to the classroom curriculum has been well-received by teachers and students alike. Conclusion: Career talks for high school students are useful for students contemplating their post- secondary career path. Relating career discussion with direct course curriculum makes their studies more relevant and engaging. Students aspiring to a career in health sciences often focus their studies on life sciences due to limited knowledge of potential careers. An early introduction to medical physics presents them with an alternate path through the physical sciences into health care.

  4. Looking at the high ability/giftedness through the lens of curriculum studies

    Soraia Napoleão Freitas


    Full Text Available From diving in the educational field, either in teaching or research in Special Education, this article postulates bring visibility to a curricular discussion strongly marked by the educational practice of learners with high ability/giftedness and having the "lighthouse flag” the inclusion policy school principles, not just theorizing about the elements of the theme. Curriculum is understood as a territory of knowledge and power, so the manufacturing process of the curriculum in the wake of the inclusive hillside – a journey which aims to solidify egalitarian social link - can put up as an potentiating agent of different actions for the education of students with high ability/giftedness, protecting them from moments of discrimination, segregation and personal, family, school and social exclusion. Therefore, this article takes up an invitation to educators to look at the prerogatives of education that hosts students with high ability/giftedness with the lens of curriculum studies.

    Frisvad, Jeppe Revall; Wyvill, Geoff


    At the moment the noise functions available in a graphics programmer's toolbox are either slow to compute or they involve grid-line artifacts making them of lower quality. In this paper we present a real-time noise computation with no grid-line artifacts or other regularity problems. In other words......, we put a new tool in the box that computes fast high-quality noise. In addition to being free of artifacts, the noise we present does not rely on tabulated data (everything is computed on the fly) and it is easy to adjust quality vs. quantity for the noise. The noise is based on point rendering (like...... spot noise), but it extends to more than two dimensions. The fact that it is based on point rendering makes art direction of the noise much easier....

  15. Using symbolic interactionism to analyze a specialized STEM high school teacher's experience in curriculum reform

    Teo, Tang Wee; Osborne, Margery


    In this paper, we present a microanalysis of a specialized STEM (science, technology, engineering, and mathematics) high school teacher's experience of self-initiated science inquiry curriculum reform. We examine the meanings of these two constructs: inquiry curriculum and curriculum change through the process lens of interactions, actions, and interpretations. Symbolic interactionism is the theoretical framework we used to frame our analysis of how this teacher, Darren Daley (a pseudonym) and various stakeholders purposefully and strategically engaged in "face-work" and act out lines of actions to advocate or oppose curriculum change. Symbols are used in this world of face-to-face encounters to communicate, imply, and assert, meanings through socially flexible and adjustable processes. We scrutinize how Daley (un)consciously engaged all of these to defend his decisions, actions, and outcomes and "look" to others as doing inquiry reform. The meanings of such work are not intrinsically driven or reactions to psychological and extraneous factors and forces, but emergent through interactions. The data collection methods include interviews with Daley, school administrators, students, and parents, lesson observations in Daley's class, and gathering of school website pages, brochures, and curriculum materials. We represent data in narratives describing storied history, voices, interactions, anecdotal accounts from individuals' experiences, and interpretations. The analysis and findings illuminate the nature of teacher agency—how it is reclaimed, sustained, reinforced, contested, exercised, and modified in more nuanced ways, hence offering an alternative lens to theorizing and empirically analyzing this construct.

  19. Electronic laboratory quality assurance program: A method of enhancing the prosthodontic curriculum and addressing accreditation standards.

    Moghadam, Marjan; Jahangiri, Leila


    An electronic quality assurance (eQA) program was developed to replace a paper-based system and to address standards introduced by the Commission on Dental Accreditation (CODA) and to improve educational outcomes. This eQA program provides feedback to predoctoral dental students on prosthodontic laboratory steps at New York University College of Dentistry. The purpose of this study was to compare the eQA program of performing laboratory quality assurance with the former paper-based format. Fourth-year predoctoral dental students (n=334) who experienced both the paper-based and the electronic version of the quality assurance program were surveyed about their experiences. Additionally, data extracted from the eQA program were analyzed to identify areas of weakness in the curriculum. The study findings revealed that 73.8% of the students preferred the eQA program to the paper-based version. The average number of treatments that did not pass quality assurance standards was 119.5 per month. This indicated a 6.34% laboratory failure rate. Further analysis of these data revealed that 62.1% of the errors were related to fixed prosthodontic treatment, 27.9% to partial removable dental prostheses, and 10% to complete removable dental prostheses in the first 18 months of program implementation. The eQA program was favored by dental students who have experienced both electronic and paper-based versions of the system. Error type analysis can yield the ability to create customized faculty standardization sessions and refine the didactic and clinical teaching of the predoctoral students. This program was also able to link patient care activity with the student's laboratory activities, thus addressing the latest requirements of the CODA regarding the competence of graduates in evaluating laboratory work related to their patient care.

  20. Development of the Astronomy-Themed Interdisciplinary Curriculum At Taipei First Girls' High School

    Yang, S.-C.; Jin, R.; Lai, S.-P.; Kong, A.; Chang, H.-K.; Wu, P.-H.


    With the advent of satellite-based telescopes and abundant data open to the public, senior high school students can now be allowed access to the latest observational data collected by those cutting-edge telescopes. Following the official guidelines for high school curricula in Taiwan, we designed a 24-hour, four-module curriculum, the themes of which are: properties of light and spectra, multi-wavelength observations, evolution of stars, and introduction to cosmology. The curriculum makes use of free online astronomical databases, software for data analysis, and teaching platforms. Many of the courses are inquiry-oriented, focusing on hands-on experiments and discussions. They can be taught separately in their own fields or combined to form research project courses as well. The curriculum development was funded by the National Science Council of Taiwan (High Scope Project) and supported by three institutes in universities. More than 700 students are participating in the pilot program. We are now promoting the curriculum to other schools, with a hope to encourage students to carry out projects on topics in astronomy.

  5. Energy: options for the future. Curriculum development project for high school teachers. Final report. [Packet

    Carroll, T.O.


    Recent state and regional energy crises demonstrate the delicate balance between energy systems, the environment, and the economy. Indeed, the interaction between these three elements of society is very complex. This project develops curriculum materials that would better provide students with an understanding and awareness of fundamental principles of energy supply, conversion processes, and utilization now and in the future. The project had two specific objectives: to transfer knowledge of energy systems, analysis techniques, and advanced technologies from the energy analyst community to the teacher participants; and to involve teachers in the preparation of modular case studies on energy issues for use within the classroom. These curriculum modules are intended to enhance the teacher's ability to provide energy-related education to students within his or her own academic setting. The project is organized as a three-week summer program, as noted in the flyer (Appendix A). Mornings are spent in seminars with energy and environmental specialists (their handout lecture notes are included as Appendix B); afternoons are devoted to high school curriculum development based on the seminar discussions. The curriculum development is limited to five areas: conservation, electricity demand scheduling, energy in the food system, new technologies (solar, wind, biomass), and environment. Appendix C consists of one-day lession plans in these areas.

    Leaphart, Cynthia L; Gonwa, Thomas A; Mai, Martin L; Prendergast, Mary B; Wadei, Hani M; Tepas, Joseph J; Taner, C Burcin


    Broad-based formal quality improvement curriculum emphasizing Six Sigma and the DMAIC approach developed by our institution is required for physicians in training. DMAIC methods evaluated the common outcome of postoperative hyponatremia, thus resulting in collaboration to prevent hyponatremia in the renal transplant population. To define postoperative hyponatremia in renal transplant recipients, a project charter outlined project aims. To measure postoperative hyponatremia, serum sodium at admission and immediately postoperative were recorded by retrospective review of renal transplant recipient charts from June 29, 2010 to December 31, 2011. An Ishikawa diagram was generated to analyze potential causative factors. Interdisciplinary collaboration and hospital policy assessment determined necessary improvements to prevent hyponatremia. Continuous monitoring in control phase was performed by establishing the goal of DMAIC approach and formal quality curriculum for trainees addresses core competencies by providing a framework for problem solving, interdisciplinary collaboration, and process improvement.

    Omer A. Agail


    Full Text Available The current study aimed to determine the quality and accreditation requirements, according to the NCAAA, for the curriculum development of the departments of Special Education as perceived by faculty members. Moreover, the study aimed to determine the relationship between the faculty awareness and other factors such as, gender, academic rank, teaching experience, participation in curriculum development, attendance of workshop, and participation in program development committees. The researcher created a survey to answer the research questions. A sample of (45 faculty members was chosen randomly from three main universities: King Khalid university, Jazan University, and Najran University.  Statistical methods were used, including mean, frequencies, one sample t–test, one way ANOVA. The results indicated that the participants' awareness toward curriculum development requirements was generally very low, because of the limited number of faculty members and the newly established departments. It was recommended that quality culture should be disseminated, and moral and material support should be provided to the programs in these departments.  Keywords: Study programs, Quality, Accreditation, Special education.

  11. Frontiers in Microbiology: Envisioning a Curriculum Unit for High School Biology

    Mark Bloom


    Microbiology is undergoing a quiet revolution. Techniques such as polymerase chain reaction, high throughput DNA sequencing, whole genome shotgun sequencing, DNA microarrays, and bioinformatics analyses are greatly aiding our understanding of the estimated one billion species of microbes that inhabit the Earth. Unfortunately, the rapid pace of research in microbiology stands in contrast to the much slower pace of change in educational reform. Biological Sciences Curriculum Study (BSCS) hosted a two-day planning meeting to discuss whether or not a new curriculum unit on microbiology is desirable for the high school audience. Attending the meeting were microbiologists, high school biology teachers, and science educators. The consensus of the participants was that an inquiry-based unit dealing with advances in microbiology should be developed for a high school biology audience. Participants established content priorities for the unit, discussed the unit's conceptual flow, brainstormed potential student activities, and discussed the role of educational technology for the unit. As a result of the planning meeting discussions, BSCS staff sought additional funding to develop, disseminate, and evaluate the Frontiers in Microbiology curriculum unit. This unit was intended to be developed as a replacement unit suitable for an introductory biology course. The unit would feature inquiry-based student activities and provide approximately four weeks of instruction. As appropriate, activities would make use of multimedia. The development and production processes would require about two years for completion. Unfortunately, BSCS staff was not able to attract sufficient funding to develop the proposed curriculum unit. Since there were some unexpended funds left over from the planning meeting, BSCS requested and received permission from DOE to use the balance of the funds to prepare background materials about advances in microbiology that would be useful to teachers. These

  12. Science curriculum effects in high school: A quantitative synthesis

    Weinstein, Thomas; Boulanger, F. David; Walberg, Herbert J.

    To assess the impact of the innovative precollege science curricula of the past twenty years on learning, a search was conducted using the computer-assisted Bibliographic Retrieval System (BRS), the ERIC Annual Summaries of Research in Science Education, and Dissertation Abstracts International. A total of 151 effect sizes were obtained from 33 studies representing 19,149 junior and senior high school students in the United States, Great Britain, and Israel. Study-weighted analysis yielded an overall mean effect size of 0.31 significantly favorable to the innovative curricula [t(25) = 2.183, p < 0.05] on all outcomes. Student performance in innovative curricula averaged in the 62nd percentile relative to the control norm. Tabulation of signed comparisons indicated that sixty-four out of eighty-one unweighted outcomes were favorable to the innovative curricula. Separate analyses for test content bias, methodological rigor, type of learning, and student characteristics showed no significant differences across these categories.

  13. Influence of Science, Technology, and Engineering Curriculum on Rural Midwestern High School Student Career Decisions

    Killingsworth, John

    Low degree completion in technical and engineering degrees is a growing concern for policymakers and educators in the United States. This study was an examination of the behaviors of adolescents specific to career decisions related to technology and engineering. The central research question for this study was: do rural, Midwestern high school technical and engineering curricula serve to engage students sufficiently to encourage them to persist through high school while sustaining their interests in technology and engineering careers? Engaging students in technology and engineering fields is the challenge for educators throughout the country and the Midwest. Rural schools have the additional challenge of meeting those issues because of resource limitations. Students in three Midwestern schools were surveyed to determine the level of interest in technology and engineering. The generalized likelihood ratio test was used to overcome concerns for small sample sizes. Accounting for dependent variables, multiple independent variables are examined using descriptive statistics to determine which have greater influence on career decisions, specifically those related to technology and engineering. A typical science curriculum is defined for rural Midwestern high schools. This study concludes that such curriculum achieves the goal of maintaining or increasing student interest and engagement in STEM careers. Furthermore, those schools that incorporate contextual and experiential learning activities into the curriculum demonstrate increased results in influencing student career choices toward technology and engineering careers. Implications for parents, educators, and industry professionals are discussed.

  14. The Pedagogical Challenges of Teaching High School Bioethics: Insights from the Exploring Bioethics Curriculum.

    Solomon, Mildred Z; Vannier, David; Chowning, Jeanne Ting; Miller, Jacqueline S; Paget, Katherine F


    A belief that high school students have the cognitive ability to analyze and assess moral choices and should be encouraged to do so but have rarely been helped to do so was the motivation for developing Exploring Bioethics, a six-module curriculum and teacher guide for grades nine through twelve on ethical issues in the life sciences. A multidisciplinary team of bioethicists, science educators, curriculum designers, scientists, and high school biology teachers worked together on the curriculum under a contract between the National Institutes of Health and Education Development Center, a nonprofit research and development organization with a long history of innovation in science education. At the NIH, the Department of Bioethics within the Clinical Center and the Office of Science Education within the Office of the Director guided the project.Our overarching goal for Exploring Bioethics was to introduce students to bioethics as a field of inquiry and to enable them to develop ethical reasoning skills so they could move beyond "gut reactions" to more nuanced positions. © 2016 The Hastings Center.

  16. Benchmarking to the world's best in mathematics. Quality control in curriculum and instruction among the top performers in the TIMSS.

    Phelps, R P


    This article describes the education quality control systems (for mathematics) used by those countries that performed best on the Third International Mathematics and Science Study (TIMSS). Enforced quality control measures are defined as "decision points"--where adherence to the curriculum and instruction system can be reinforced. Most decision points involve stakes for the student, teacher, or school. They involve potential consequences for failure to adhere to the system and to follow the program at a reasonable pace. Generally, countries with more decision points perform better on the TIMSS. When the number of decision points and TIMSS test scores are adjusted for country wealth, the relationship between the degree of (enforced) quality control and student achievement appears to be positive and exponential. The more (enforced) quality control measures employed in an education system, the greater is students' academic achievement.

  18. A high school ecology curriculum employing currere: A critical postmodern approach to pedagogy

    Doerr, Marilyn Noble


    This classroom research is a case study of a high school ecology curriculum based on William Pinar's currere. The author, both the practitioner in the classroom and the curriculum developer, uses the dissertation to analyze the success of the ecology course. A successful course, she feels, not only teaches the students the rudiments of ecology but also introduces them to the political and moral issues surrounding ecological principles. Currere is curriculum as autobiographical text. It is phenomenological, exploring students' lived experiences and their interpretations of those experiences. With the focus on introspection and hermeneutics, curriculum becomes something to be encountered and the student immerses her/himself in trying to understand that encounter. In this study, currere is adapted for use in an ecology classroom through what the author terms "the Environmental Autobiography," or EA. The paper explores qualitative data collected from the researcher and 50 students, mostly high school seniors, who took the class over a two-year period. The researcher analyzes and interprets a generous selection of excerpts from these EAs when considering the efficacy of using the currere process in this course. The researcher then examines five frequently-appearing themes in the writings: caring, insecurities and gender issues, egocentrism, politicization, and definitions of success. The researcher finds that the use of currere in this way brought a postmodern approach to the teaching of this most holistic of the sciences---ecology. This non-traditional method allowed students to begin to see ecological problems in context and to realize that knowledge is always partial. For many students this currere-based ecology curriculum moved them from "I know" to "I care," and on to "I want to do something about this." Finally, the researcher concludes that the EA gave a richness and energy to the class that was unlike any of her past teaching experiences. The paper explores

  19. Investigating stakeholders' perceptions of the link between high STD rates and the current Baltimore City Public Schools' sex education curriculum

    Bolden, Shenell L. T.

    The purpose of this exploratory study was to examine key stakeholders' perceptions of the current Baltimore City Public Schools' (BCPS) sex education curriculum and to gain insight into how they believe the curriculum could be modified to be more effective. A mixed methods approach using qualitative and quantitative data collection consisting of a survey, focus group interview, and individual interviews was conducted to gather information on stakeholders' perceptions. The stakeholders included: (1) former students who received their sex education courses in the Baltimore City Public School system (BCPS); (2) teachers in BCPS who were affiliated with the sex education curriculum; (3) health care professionals who screened and/or treated East Baltimore City residents for a sexually transmitted disease (STD) and; (4) one policy maker who was responsible for creating sex education curriculum at the national level. Analysis of the quantitative data from former Baltimore City Public School students revealed a general satisfaction with the current sex education curriculum. However, qualitative data from the same group of stakeholders revealed several changes they thought should be implemented into the program in an effort to improve the current curriculum. Findings from the other groups after qualitative analysis of the interviews suggest three major themes in support of curriculum change: (1) a blended curriculum that integrates both the cognitive and affective learning domains; (2) knowledge of prevention of STD's and pregnancy; and (3) authentic teaching and learning. Results from this study strongly suggest that the Baltimore City Public School system is apathetic to the sexual health needs of students and, therefore, is inadvertently contributing to the high rate of sexually transmitted diseases among young people.

  20. Development of Integrative STEM Curriculum: A Multiple Case Study of Multi-Disciplinary Teams in Two Pennsylvania High Schools

    Rider-Bertrand, Joey H.

    At the start of the 21st century, STEM education was a new priority in many schools as the focus shifted from separate disciplines to integrative STEM education. Unfortunately, there was limited research to offer guidance to practitioners (Brown, 2012; Honey, Pearson & Schweingruber, 2014). This qualitative, multiple case study explored the experiences of two multi-disciplinary teams of secondary teachers from Pennsylvania who developed and implemented integrative STEM curriculum. Four teachers from a rural high school and four teachers from a suburban high school participated in the study. A document review of integrative STEM curriculum and semi-structured interviews were conducted to learn about the curriculum development process and teachers' perceptions regarding conditions that support or hinder success. Individual and cross-case analyses were performed to establish findings and themes. Although the individual case themes varied slightly, the cross-case themes and assertions that emerged provided highly sought after guidance to practitioners and added to the limited body of research on integrative STEM education. This study found that current curriculum models do not fit integrative STEM curriculum, the development process is fluid, and substantial administrative support and resources are necessary to develop, implement, and sustain integrative STEM education programs. The results offered implications for all educators, as well as two examples of how teachers navigated the terrain of integrative STEM curriculum.

  1. Designing an educative curriculum unit for teaching molecular geometry in high school chemistry

    Makarious, Nader N.

    Chemistry is a highly abstract discipline that is taught and learned with the aid of various models. Among the most challenging, yet a fundamental topic in general chemistry at the high school level, is molecular geometry. This study focused on developing exemplary educative curriculum materials pertaining to the topic of molecular geometry. The methodology used in this study consisted of several steps. First, a diverse set of models were analyzed to determine to what extent each model serves its purpose in teaching molecular geometry. Second, a number of high school teachers and college chemistry professors were asked to share their experiences on using models in teaching molecular geometry through an online questionnaire. Third, findings from the comparative analysis of models, teachers’ experiences, literature review on models and students’ misconceptions, the curriculum expectations of the Next Generation Science Standards and their emphasis on three-dimensional learning and nature of science (NOS) contributed to the development of the molecular geometry unit. Fourth, the developed unit was reviewed by fellow teachers and doctoral-level science education experts and was revised to further improve its coherence and clarity in support of teaching and learning of the molecular geometry concepts. The produced educative curriculum materials focus on the scientific practice of developing and using models as promoted in the Next Generations Science Standards (NGSS) while also addressing nature of science (NOS) goals. The educative features of the newly developed unit support teachers’ pedagogical knowledge (PK) and pedagogical content knowledge (PCK). The unit includes an overview, teacher’s guide, and eight detailed lesson plans with inquiry oriented modeling activities replete with models and suggestions for teachers, as well as formative and summative assessment tasks. The unit design process serves as a model for redesigning other instructional units in

  2. Zerodur polishing process for high surface quality and high efficiency

    Tesar, A.; Fuchs, B.


    Zerodur is a glass-ceramic composite importance in applications where temperature instabilities influence optical and mechanical performance, such as in earthbound and spaceborne telescope mirror substrates. Polished Zerodur surfaces of high quality have been required for laser gyro mirrors. Polished surface quality of substrates affects performance of high reflection coatings. Thus, the interest in improving Zerodur polished surface quality has become more general. Beyond eliminating subsurface damage, high quality surfaces are produced by reducing the amount of hydrated material redeposited on the surface during polishing. With the proper control of polishing parameters, such surfaces exhibit roughnesses of < l Angstrom rms. Zerodur polishing was studied to recommend a high surface quality polishing process which could be easily adapted to standard planetary continuous polishing machines and spindles. This summary contains information on a polishing process developed at LLNL which reproducibly provides high quality polished Zerodur surfaces at very high polishing efficiencies

  4. Integrating a relaxation response-based curriculum into a public high school in Massachusetts.

    Foret, Megan M; Scult, Matthew; Wilcher, Marilyn; Chudnofsky, Rana; Malloy, Laura; Hasheminejad, Nicole; Park, Elyse R


    Academic and societal pressures result in U.S. high school students feeling stressed. Stress management and relaxation interventions may help students increase resiliency to stress and overall well-being. The objectives of this study were to examine the feasibility (enrollment, participation and acceptability) and potential effectiveness (changes in perceived stress, anxiety, self-esteem, health-promoting behaviors, and locus of control) of a relaxation response (RR)-based curriculum integrated into the school day for high school students. The curriculum included didactic instruction, relaxation exercises, positive psychology, and cognitive restructuring. The intervention group showed significantly greater improvements in levels of perceived stress, state anxiety, and health-promoting behaviors when compared to the wait list control group. The intervention appeared most useful for girls in the intervention group. The results suggest that several modifications may increase the feasibility of using this potentially effective intervention in high schools.

  5. Challenging traditional assumptions of high school science through the physics and Everyday Thinking Curriculum(TM)

    Ross, Michael J.

    Science education in the U.S. has failed for over a century to bring the experience of scientific induction to classrooms, from elementary science to undergraduate courses. The achievement of American students on international comparisons of science proficiency is unacceptable, and the disparities between groups underrepresented in STEM and others are large and resistant to reform efforts. This study investigated the enactment of a physics curriculum designed upon the inductive method in a high school serving mostly students from groups underrepresented in science. The Physics and Everyday Thinking curriculum was designed to model the central practices of science and to provide opportunities for students to both extract general principles of physics and to develop scientific models from laboratory evidence. The findings of this study suggest that scientific induction is not only a process that is well within the capacity of high school students, but they enjoy it as well. Students that engaged in the central practices of science through the inductive method reported a new sense of agency and control in their learning. These findings suggest that modeling the pedagogy of the science classroom upon the epistemology of science can result in a mode of learning that can lead to positive identification with physics and the development of scientific literacy.

    Milin, Robert; Kutcher, Stanley; Lewis, Stephen P; Walker, Selena; Wei, Yifeng; Ferrill, Natasha; Armstrong, Michael A


    This study evaluated the effectiveness of a school-based mental health literacy intervention for adolescents on knowledge and stigma. A total of 24 high schools and 534 students in the regional area of Ottawa, Ontario, Canada participated in this randomized controlled trial. Schools were randomly assigned to either the curriculum or control condition. The curriculum was integrated into the province's grade 11 and 12 "Healthy Living" courses and was delivered by teachers. Changes in mental health knowledge and stigma were measured using pre- and posttest questionnaires. Descriptive analyses were conducted to provide sample characteristics, and multilevel modeling was used to examine study outcomes. For the curriculum condition, there was a significant change in stigma scores over time (p = .001), with positive attitudes toward mental illness increasing from pre to post. There was also a significant change in knowledge scores over time (p mental health (p mental health literacy of an integrated, manualized mental health educational resource for high school students on knowledge and stigma.

  7. Quality management manual for production of high quality cassava flour

    Dziedzoave, Nanam Tay; Abass, Adebayo Busura; Amoa-Awua, Wisdom K.

    The high quality cassava flour (HQCF) industry has just started to evolve in Africa and elsewhere. The sustainability of the growing industry, the profitability of small- and medium-scale enterprises (SMEs) that are active in the industry and good-health of consumers can best be guaranteed through...... the adoption of proper quality and food safety procedures. Cassava processing enterprises involved in the productionof HQCF must therefore be commited to the quality and food safety of the HQCF. They must have the right technology, appropriate processing machhinery, standard testing instruments...... and the necessary technical expertise. This quality manual was therefore developed to guide small- to medium-scale cassava in the design and implematation of Hazard Analysis Critical Control Point (HACCP) system and Good manufacturing Practices (GMP) plans for HQCF production. It describes the HQCF production...

    The lack of a national reproductive biology curriculum leads to critical knowledge gaps in today's high school students' comprehensive understanding of human biology. The Oncofertility Consortium developed curricula that address the basic and clinical aspects of reproductive biology. Launching this academy and creating easy-to-disseminate learning modules allowed other universities to implement similar programs across the country. The expansion of this informal, extracurricular academy on reproductive health from Northwestern University to the University of California, San Diego, Oregon Health & Science University, and the University of Pennsylvania magnifies the scope of scientific learning to students who might not otherwise be exposed to this important information. To assess the experience gained from this curriculum, we polled alumni from the four centers. Data were collected anonymously from de-identified users who elected to self-report on their experiences in their respective reproductive science academy. The alumni survey asked participants to report on their current academic standing, past experiences in the academy, and future academic and career goals. The results of this national survey suggest the national oncofertility academies had a lasting impact on participants and may have contributed to student persistence in scientific learning. © 2016 by the Society for the Study of Reproduction, Inc.

  10. High-Fidelity Simulation in Occupational Therapy Curriculum: Impact on Level II Fieldwork Performance

    Rebecca Ozelie


    Full Text Available Simulation experiences provide experiential learning opportunities during artificially produced real-life medical situations in a safe environment. Evidence supports using simulation in health care education yet limited quantitative evidence exists in occupational therapy. This study aimed to evaluate the differences in scores on the AOTA Fieldwork Performance Evaluation for the Occupational Therapy Student of Level II occupational therapy students who received high-fidelity simulation training and students who did not. A retrospective analysis of 180 students from a private university was used. Independent samples nonparametric t tests examined mean differences between Fieldwork Performance Evaluation scores of those who did and did not receive simulation experiences in the curriculum. Mean ranks were also analyzed for subsection scores and practice settings. Results of this study found no significant difference in overall Fieldwork Performance Evaluation scores between the two groups. The students who completed simulation and had fieldwork in inpatient rehabilitation had the greatest increase in mean rank scores and increases in several subsections. The outcome measure used in this study was found to have limited discriminatory capability and may have affected the results; however, this study finds that using simulation may be a beneficial supplement to didactic coursework in occupational therapy curriculums.

  11. High educational impact of a national simulation-based urological curriculum including technical and non-technical skills.

    de Vries, Anna H; Schout, Barbara M A; van Merriënboer, Jeroen J G; Pelger, Rob C M; Koldewijn, Evert L; Muijtjens, Arno M M; Wagner, Cordula


    Although simulation training is increasingly used to meet modern technology and patient safety demands, its successful integration within surgical curricula is still rare. The Dutch Urological Practical Skills (D-UPS) curriculum provides modular simulation-based training of technical and non-technical basic urological skills in the local hospital setting. This study aims to assess the educational impact of implementing the D-UPS curriculum in the Netherlands and to provide focus points for improvement of the D-UPS curriculum according to the participants. Educational impact was assessed by means of qualitative individual module-specific feedback and a quantitative cross-sectional survey among residents and supervisors. Twenty out of 26 Dutch teaching hospitals participated. The survey focussed on practical aspects, the D-UPS curriculum in general, and the impact of the D-UPS curriculum on the development of technical and non-technical skills. A considerable survey response of 95 % for residents and 76 % for supervisors was obtained. Modules were attended by junior and senior residents, supervised by a urologist, and peer teaching was used. Ninety percent of supervisors versus 67 % of residents judged the D-UPS curriculum as an important addition to current residency training (p = 0.007). Participants' aggregated general judgement of the modules showed a substantial percentage favorable score (M ± SE: 57 ± 4 %). The impact of training on, e.g., knowledge of materials/equipment and ability to anticipate on complications was high, especially for junior residents (77 ± 5 and 71 ± 7 %, respectively). Focus points for improvement of the D-UPS curriculum according to the participants include adaptation of the training level to residents' level of experience and focus on logistics. The simulation-based D-UPS curriculum has a high educational impact. Residents and supervisors consider the curriculum to be an important addition to current residency

    Huang, Heyan; Zhou, Cheng; Tian, Tian; Liu, Dongqi; Song, Lijun


    We propose a high-quality compressive ghost imaging method based on projected Landweber regularization and guided filter, which effectively reduce the undersampling noise and improve the resolution. In our scheme, the original object is reconstructed by decomposing of regularization and denoising steps instead of solving a minimization problem in compressive reconstruction process. The simulation and experimental results show that our method can obtain high ghost imaging quality in terms of PSNR and visual observation.

  15. Developing a Curriculum for Remote Research Mentoring of Virginia High School Students

    Dirienzo, William J.; Corby, J.; Beaton, R.; Barcos-Munoz, L. D.; Jones, K. M.; Pennucci, T.


    Graduate students at the University of Virginia (UVa) are volunteering as research advisors on astronomy projects for Virginia's science and technology high schools. Over five years, we have worked with more than a dozen students through a research class at Central Virginia Governor's School for Science and Technology in Lynchburg and two students last year at Roanoke Valley Governor's School in Roanoke to develop an astronomy research curriculum that teaches background concepts and terminology, guides students in data analysis, and prepares them to present material in poster and oral forums. Because both schools are far from UVa in Charlottesville, the program operates remotely; graduate advisors and high school students interact through "virtual" means, establishing a successful framework for meaningful remote mentoring. In the current year, four students will complete projects on astrophysical topics including megamasers and astrochemistry using data taken by the Robert C. Byrd Green Bank Telescope (GBT). Previous topics also include pulsar searches, extended green object (EGO) searches, and the X-ray properties of YSOs in the Carina complex. All four students this year will receive hands-on experience in handling GBT data. The current projects are components of larger research efforts by graduate student and professional level researchers, so that the projects contribute to high-level projects only possible with the GBT. This stands as a rare outreach program that uses the principle of “deliberative practice” to train high school students in the development of skills that are crucial to success in science. Furthermore, it provides graduate students with an opportunity to plan and advise research projects, developing a skill set that is required in more advanced academic positions. Our poster discusses the implementation of our online curriculum in two distinct class settings and highlights the students' research contributions.

  16. Engineering the curriculum: Towards an adaptive curriculum

    Johns-Boast, Lynette Frances

    cohesiveness. Without integrity, a curriculum is unlikely to be able to deliver all its required outcomes. Utilising the concepts of system dynamics and systems thinking I propose that not only is the curriculum a complex adaptive system, it is a multi-dimensional object. Adopting this notion facilitates possible interventions that may be used to monitor the curriculum and to moderate the effects of curriculum drift. I argue that using the articulated purpose of the curriculum to determine the desired outcomes of that curriculum will enhance curricular alignment, leading to improved student learning and outcomes. Furthermore, perceiving the curriculum as a multi-dimensional object reinforces the proposition that aligning the purpose and desired outcomes of each course with those of the program will achieve improved desired outcomes from the program as a whole. The original contributions to knowledge arising from this research are curriculum drift, an enhanced approach to the curricular alignment, and a multi-dimensional view of curriculum. Perhaps the most important implication of this research, is insight into how we might incorporate curriculum drift into curriculum review models. Successful incorporation has the potential to deliver increased quality of educational outcomes by enabling innovation whilst maintaining the integrity of the curriculum.

  19. Educational system factors that engage resident physicians in an integrated quality improvement curriculum at a VA hospital: a realist evaluation.

    Ogrinc, Greg; Ercolano, Ellyn; Cohen, Emily S; Harwood, Beth; Baum, Karyn; van Aalst, Robertus; Jones, Anne C; Davies, Louise


    Learning about quality improvement (QI) in resident physician training is often relegated to elective or noncore clinical activities. The authors integrated teaching, learning, and doing QI into the routine clinical work of inpatient internal medicine teams at a Veterans Affairs (VA) hospital. This study describes the design factors that facilitated and inhibited the integration of a QI curriculum-including real QI work-into the routine work of inpatient internal medicine teams. A realist evaluation framework used three data sources: field notes from QI faculty; semistructured interviews with resident physicians; and a group interview with QI faculty and staff. From April 2011 to July 2012, resident physician teams at the White River Junction VA Medical Center used the Model for Improvement for their QI work and analyzed data using statistical process control charts. Three domains affected the delivery of the QI curriculum and engagement of residents in QI work: setting, learner, and teacher. The constant presence of the QI material on a public space in the team workroom was a facilitating mechanism in the setting. Explicit sign-out of QI work to the next resident team formalized the handoff in the learner domain. QI teachers who were respected clinical leaders with QI expertise provided role modeling and local system knowledge. Integrating QI teaching into the routine clinical and educational systems of an inpatient service is challenging. Identifiable, concrete strategies in the setting, learner, and teacher domains helped integrate QI into the clinical and educational systems.

  1. Fabrication of high-quality brazed joints

    Orlov, A.V.


    Problem of ensuring of joint high-quality when brazing different parts in power engineering is considered. To obtain high-quality joints it is necessary to correctly design brazed joint and to choose a gap width, overlap length and fillet radius; to clean up carefully the surfaces to be brazed and fix them properly one relative to another; to apply a solder so as to provide its flowing into the gap and sticking in it; to exactly regulate thermal conditions of brazing. High quality and reliability of brazed joints are ensured by the application of solders based on noble metals, and cheap solders based on nickel, manganese and copper. Joints brazed with nickel base solders may operate at temperatures as high as 888 deg C


    Hasan SERİN, Alper AYTEKİN


    Full Text Available The approach of Total Quality Management (TQM has been even more common and most recently its use in high education has been discussed. Likewise the enterprises producing various products, universities have also inputs, processes, and outputs. Due to conditions of competition, universities have to improve the qualities of these inputs, processes, and outputs, according to satisfaction, demands, and expectations of internal and external customers. If the TQM has been implemented in the universities with a manner that aims for customer satisfaction (students, lecturers, public and private establishments, and families, supports constant development, ensures participatory approach, and encourages working in groups, it will provide universities with effectiveness, efficiency, dynamics, and economics. In this study, common problems of universities, definitions of quality and TQM in high education, customer concept at universities, and factors affecting the quality of education have been explained. Besides, in order TQM approach to be successfully implemented in the universities, various suggestions have been presented.

  9. Assuring quality in high-consequence engineering

    Hoover, Marcey L.; Kolb, Rachel R.


    In high-consequence engineering organizations, such as Sandia, quality assurance may be heavily dependent on staff competency. Competency-dependent quality assurance models are at risk when the environment changes, as it has with increasing attrition rates, budget and schedule cuts, and competing program priorities. Risks in Sandia's competency-dependent culture can be mitigated through changes to hiring, training, and customer engagement approaches to manage people, partners, and products. Sandia's technical quality engineering organization has been able to mitigate corporate-level risks by driving changes that benefit all departments, and in doing so has assured Sandia's commitment to excellence in high-consequence engineering and national service.

  13. Evaluation of oral microbiology lab curriculum reform.

    Nie, Min; Gao, Zhen Y; Wu, Xin Y; Jiang, Chen X; Du, Jia H


    According to the updated concept of oral microbiology, the School of Stomatology, Wuhan University, has carried out oral microbiology teaching reforms during the last 5 years. There was no lab curriculum before 2009 except for a theory course of oral microbiology. The school has implemented an innovative curriculum with oral medicine characteristics to strengthen understanding of knowledge, cultivate students' scientific interest and develop their potential, to cultivate the comprehensive ability of students. This study was designed to evaluate the oral microbiology lab curriculum by analyzing student performance and perceptions regarding the curriculum from 2009 to 2013. The lab curriculum adopted modalities for cooperative learning. Students collected dental plaque from each other and isolated the cariogenic bacteria with selective medium plates. Then they purified the enrichment culture medium and identified the cariogenic strains by Gram stain and biochemical tests. Both quantitative and qualitative data for 5 years were analysed in this study. Part One of the current study assessed student performance in the lab from 2009 to 2013. Part Two used qualitative means to assess students' perceptions by an open questionnaire. The 271 study students' grades on oral microbiology improved during the lab curriculum: "A" grades rose from 60.5 to 81.2 %, and "C" grades fell from 28.4 to 6.3 %. All students considered the lab curriculum to be interesting and helpful. Quantitative and qualitative data converge to suggest that the lab curriculum has strengthened students' grasp of important microbiology-related theory, cultivated their scientific interest, and developed their potential and comprehensive abilities. Our student performance and perception data support the continued use of the innovative teaching system. As an extension and complement of the theory course, the oral microbiology lab curriculum appears to improve the quality of oral medicine education and help to

  15. Reaching teen farm workers with health and safety information: an evaluation of a high school ESL curriculum.

    Teran, S; Strochlic, R; Bush, D; Baker, R; Meyers, J


    While childhood agricultural injury has long been recognized as an important public health issue, most research has focused on family farms and there have not been many interventions targeting hired youth. This study evaluated the impact of a high school English as a Second Language (ESL) curriculum, designed to provide teen agricultural workers with the knowledge and tools to protect their health and safety in the fields. Using a quasi-experimental design, the research consisted of two intervention groups and a comparison group, and included over 2,000 students from communities that lead California in agricultural production. The research findings revealed that the curriculum had significant impact in terms of increases in knowledge and attitudes, and nearly half of those interviewed after a summer of working in the fields reported implementing new behaviors to protect their health and safety. The curriculum also had extended effects in the broader community, as the majority of students reported sharing the new information with others. The study found that a school-based ESL curriculum is an effective intervention to reach and educate teen farm workers and that ESL classes can serve as a much-needed access point for young farm workers.

    Wilson, H Kent; Scult, Matthew; Wilcher, Marilyn; Chudnofsky, Rana; Malloy, Laura; Drewel, Emily; Riklin, Eric; Saul, Southey; Fricchione, Gregory L; Benson, Herbert; Denninger, John W


    Recent data suggest that severe stress during the adolescent period is becoming a problem of epidemic proportions. Elicitation of the relaxation response (RR) has been shown to be effective in treating anxiety, reducing stress, and increasing positive health behaviors. The research team's objective was to assess the impact of an RR-based curriculum, led by teachers, on the psychological status and health management behaviors of high-school students and to determine whether a train-the-trainer model would be feasible in a high-school setting. The research team designed a pilot study. The setting was a Horace Mann charter school within Boston's public school system. Participants were teachers and students at the charter school. The team taught teachers a curriculum that included (1) relaxation strategies, such as breathing and imagery; (2) psychoeducation regarding mind-body pathways; and (3) positive psychology. Teachers implemented this curriculum with students. The research team assessed changes in student outcomes (eg, stress, anxiety, and stress management behaviors) using preintervention/postintervention surveys, including the Perceived Stress Scale (PSS), the State-Trait Anxiety Inventory-Form Y (STAI-Y), the stress management subscale of the Health-promoting Lifestyle Profile II (HPLP-II), the Rosenberg Self-Esteem Scale (RSES), the Locus of Control (LOC) questionnaire, and the Life Orientation Test-Revised (LOTR). Classroom observations using the Classroom Assessment Scoring System (CLASS)-Secondary were also completed to assess changes in classroom environment. Using a Bonferroni correction (P management behaviors at that point. Using a Bonferroni correction (P management behaviors (P classroom productivity (eg, increased time spent on activities and instruction from pre- to postintervention). This study showed that teachers can lead an RR curriculum with fidelity and suggests that such a curriculum has positive benefits on student emotional and behavioral

  17. Doctors of tomorrow: An innovative curriculum connecting underrepresented minority high school students to medical school.

    Derck, Jordan; Zahn, Kate; Finks, Jonathan F; Mand, Simanjit; Sandhu, Gurjit


    Racial minorities continue to be underrepresented in medicine (URiM). Increasing provider diversity is an essential component of addressing disparity in health delivery and outcomes. The pool of students URiM that are competitive applicants to medical school is often limited early on by educational inequalities in primary and secondary schooling. A growing body of evidence recognizing the importance of diversifying health professions advances the need for medical schools to develop outreach collaborations with primary and secondary schools to attract URiMs. The goal of this paper is to describe and evaluate a program that seeks to create a pipeline for URiMs early in secondary schooling by connecting these students with support and resources in the medical community that may be transformative in empowering these students to be stronger university and medical school applicants. The authors described a medical student-led, action-oriented pipeline program, Doctors of Tomorrow, which connects faculty and medical students at the University of Michigan Medical School with 9th grade students at Cass Technical High School (Cass Tech) in Detroit, Michigan. The program includes a core curriculum of hands-on experiential learning, development, and presentation of a capstone project, and mentoring of 9th grade students by medical students. Cass Tech student feedback was collected using focus groups, critical incident written narratives, and individual interviews. Medical student feedback was collected reviewing monthly meeting minutes from the Doctors of Tomorrow medical student leadership. Data were analyzed using thematic analysis. Two strong themes emerged from the Cass Tech student feedback: (i) Personal identity and its perceived effect on goal achievement and (ii) positive affect of direct mentorship and engagement with current healthcare providers through Doctors of Tomorrow. A challenge noted by the medical students was the lack of structured curriculum beyond the 1st

  2. High quality transportation fuels from renewable feedstock

    Lindfors, Lars Peter


    Hydrotreating of vegetable oils is novel process for producing high quality renewable diesel. Hydrotreated vegetable oils (HVO) are paraffinic hydrocarbons. They are free of aromatics, have high cetane numbers and reduce emissions. HVO can be used as component or as such. HVO processes can also be modified to produce jet fuel. GHG savings by HVO use are significant compared to fossil fuels. HVO is already in commercial production. Neste Oil is producing its NExBTL diesel in two plants. Production of renewable fuels will be limited by availability of sustainable feedstock. Therefore R and D efforts are made to expand feedstock base further.

  3. Boiling curve in high quality flow boiling

    Shiralkar, B.S.; Hein, R.A.; Yadigaroglu, G.


    The post dry-out heat transfer regime of the flow boiling curve was investigated experimentally for high pressure water at high qualities. The test section was a short round tube located downstream of a hot patch created by a temperature controlled segment of tubing. Results from the experiment showed that the distance from the dryout point has a significant effect on the downstream temperatures and there was no unique boiling curve. The heat transfer coefficients measured sufficiently downstream of the dryout point could be correlated using the Heineman correlation for superheated steam, indicating that the droplet deposition effects could be neglected in this region

  6. Introducing quality assurance and medical audit into the UCSF medical center curriculum.

    Barbaccia, J C


    The experience gained by a medical school faculty in developing and piloting a course for undergraduate medical students in medical care evaluation led to a similar effort for house staff. It is recognized that if the profession is to fulfill the demand by society for social accountability in the use of resources for health care, medical care assessment and quality assurance mechanisms must become an intimate part of the clinical experience of medical students and house officers. Teaching these subjects requires a theoretical framework; introduction of content and skills appropriate to the level of the student and continuation of progressively more advanced training throughout medical education; use of assessment and quality assurance techniques by clinician-teachers themselves to provide models for the student; and continued evolution of pedagogic approach and course content based on developments in the area.

  7. Development of a Quality and Safety Competency Curriculum for Radiation Oncology Residency: An International Delphi Study

    Adleman, Jenna; Gillan, Caitlin; Caissie, Amanda; Davis, Carol-Anne; Liszewski, Brian; McNiven, Andrea; Giuliani, Meredith


    Purpose: To develop an entry-to-practice quality and safety competency profile for radiation oncology residency. Methods and Materials: A comprehensive list of potential quality and safety competency items was generated from public and professional resources and interprofessional focus groups. Redundant or out-of-scope items were eliminated through investigator consensus. Remaining items were subjected to an international 2-round modified Delphi process involving experts in radiation oncology, radiation therapy, and medical physics. During Round 1, each item was scored independently on a 9-point Likert scale indicating appropriateness for inclusion in the competency profile. Items indistinctly ranked for inclusion or exclusion were re-evaluated through web conference discussion and reranked in Round 2. Results: An initial 1211 items were compiled from 32 international sources and distilled to 105 unique potential quality and safety competency items. Fifteen of the 50 invited experts participated in round 1: 10 radiation oncologists, 4 radiation therapists, and 1 medical physicist from 13 centers in 5 countries. Round 1 rankings resulted in 80 items included, 1 item excluded, and 24 items indeterminate. Two areas emerged more prominently within the latter group: change management and human factors. Web conference with 5 participants resulted in 9 of these 24 items edited for content or clarity. In Round 2, 12 participants rescored all indeterminate items resulting in 10 items ranked for inclusion. The final 90 enabling competency items were organized into thematic groups consisting of 18 key competencies under headings adapted from Deming's System of Profound Knowledge. Conclusions: This quality and safety competency profile may inform minimum training standards for radiation oncology residency programs.

    Background : Teaching the practice of high-value care (HVC) is an increasingly important function of graduate medical education but best practices and long-term outcomes remain unknown. Objective : Whether a multimodal curriculum designed to address specific drivers of low-value care would affect resident attitudes, skills, and performance of HVC as tested by the Internal Medicine In-Training Exam (ITE). Methods : In 2012, we performed a baseline needs assessment among internal medicine residents at a community program regarding drivers of healthcare utilization. We then created a multimodal curriculum with online interactive worksheets, lectures, and faculty buy-in to target specific skills, knowledge, and culture deficiencies. Perceived drivers of care and performance on the Internal Medicine ITE were assessed yearly through 2016. Results : Fourteen of 27 (52%) residents completed the initial needs assessment while the curriculum was eventually seen by at least 24 of 27 (89%). The ITE was taken by every resident every year. Long-term, 3-year follow-up demonstrated persistent improvement in many drivers of utilization (patient requests, reliance on subspecialists, defensive medicine, and academic curiosity) and improvement with sustained high performance on the high-value component of the ITE. Conclusion : A multimodal curriculum targeting specific drivers of low-value care can change culture and lead to sustained improvement in the practice of HVC.

  15. Emergency medicine clerkship curriculum in a high-income developing country: methods for development and application.

    Cevik, Arif Alper; Cakal, Elif Dilek; Abu-Zidan, Fikri M


    The published recommendations for international emergency medicine curricula cover the content, but exclude teaching and learning methods, assessment, and evaluation. We aim to provide an overview on available emergency medicine clerkship curricula and report the development and application experience of our own curriculum. Our curriculum is an outcome-based education, enriched by e-learning and various up-to-date pedagogic principles. Teaching and learning methods, assessment, and evaluation are described. The theory behind our practice in the light of recent literature is discussed aiming to help other colleagues from developing countries to have a clear map for developing and tailoring their own curricula depending on their needs. The details of our emergency medicine clerkship will serve as an example for developing and developed countries having immature undergraduate emergency medicine clerkship curricula. However, these recommendations will differ in various settings depending on available resources. The main concept of curriculum development is to create a curriculum having learning outcomes and content relevant to the local context, and then align the teaching and learning activities, assessments, and evaluations to be in harmony. This may assure favorable educational outcome even in resource limited settings.

  1. High-level radioactive waste curriculum usage, evaluation, and customer focus

    King, G.P.


    In August 1992, the U.S. Department of Energy's Office of Civilian Radioactive Waste Management (OCRWM) issued for educator use, a secondary school resource curriculum entitled open-quotes Science, Society, and America's Nuclear Wasteclose quotes. This resource curriculum was developed in response to years and thousands of teacher, student, and general public requests for facts about nuclear waste -- specifically, what the United States was doing and why. The curriculum materials when issued were the result of six years of development and testing by science and social studies teachers as well as multi-state field-testing and international critique. The curriculum is provided only to educators who specifically request it; and in the first one-and-a-half years following its availability more than 500,000 curriculum documents have been requested. Of all the requests for information received by OCRWM for any information or materials, most requests received are from educators or students. So one might consider educators and students to be open-quotes customerclose quotes, that is, as the business world might define customers: anyone expecting a product or a service from us. To determine usefulness and content for future editions of open-quotes Science, Society, and America's Nuclear Wasteclose quotes, the Office of Civilian Radioactive Waste Management has undertaken a usage evaluation to ensure that it focuses on the needs of the open-quotes customerclose quotes; that is, those who need and request it. This paper presents preliminary findings based on a formal evaluation provided to and requested from educators, unsolicited comments received from educator requesters of the material, and comments from others

  2. Using an Inpatient Quality Improvement Curriculum for Internal Medicine Residents to Improve Pneumococcal Conjugate Vaccine Administration Rates.

    Jolin, Jonathan; van Aalst, Robertus; Volpp, Bryan; Taylor, Thomas; Cohen, Emily


    Pneumococcal infections are an important source of morbidity and mortality in older adults and persons with compromised immune systems. New recommendations from the Advisory Committee on Immunization Practices (ACIP) became available September 2014, which included recommendations for the use of the 13-valent pneumococcal conjugate vaccine (PCV13). A study was conducted to increase the PCV13 vaccination rates of hospitalized patients at the White River Junction Veterans Affairs Medical Center (White River Junction, Vermont) through the use of a resident-driven quality improvement (QI) project. From December 2014 through April 2016, 16 internal medicine inpatient residents addressed inpatient PCV13 vaccination rates by participating in the facility's QI curriculum. Eight Plan-Do-Study-Act cycles were used, including discharge template editing, electronic reminders, and the discovery of a vaccination administration documentation error in the record through data validation. The measure was the monthly percentage of patients who received PCV13 vaccination (vaccination completion rate) of those discharged from the hospital medicine service who were due for PCV13 vaccination. The percentage of veterans discharged with an up-to-date PCV13 vaccination on discharge increased from approximately 30% to 87% and was sustained. Despite being driven by many different residents, this project demonstrates that continuous improvement can be achieved through a structured and iterative process while providing active learning of core QI concepts to residents. It also displays a method in which new guidelines can be incorporated into practice in an effective manner. Finally, this project is an example of how resident-driven data validation can lead to further improvement. Published by Elsevier Inc.

  3. Method for synthesis of high quality graphene

    A method is described herein for the providing of high quality graphene layers on silicon carbide wafers in a thermal process. With two wafers facing each other in close proximity, in a first vacuum heating stage, while maintained at a vacuum of around 10.sup.-6 Torr, the wafer temperature is raised to about C., whereby silicon evaporates from the wafer leaving a carbon rich surface, the evaporated silicon trapped in the gap between the wafers, such that the higher vapor pressure of silicon above each of the wafers suppresses further silicon evaporation. As the temperature of the wafers is raised to about C. or more, the carbon atoms self assemble themselves into graphene.

  5. High-picture quality industrial CT scanner

    Shoji, Takao; Nishide, Akihiko; Fujii, Masashi.


    Industrial X-ray-CT-scanners, which provide cross-sectional images of a tested sample without destroying it, are attracting attention as a new nondestructive inspection device. In 1982, Toshiba commenced the development of industrial CT scanners, and introduced the 'TOSCANER' -3000 and-4000 series. Now, the state of the art 'TOSCANER'-20000 series of CT systems has been developed incorporating the latest computer tomography and image processing technology, such as the T9506 image processor. One of the advantages of this system is its applicability to a wide range of X-ray energy . The 'TOSCANER'-20000 series can be utilized for inspecting castings and other materials with relatively low-transparency to X-rays, as well as ceramics, composite materials and other materials with high X-ray transparency. A further feature of the new system is its high-picture quality, with a high-spatial resolution resulting from a pixel size of 0.2x0.2(mm). (author)

  7. Optical studies of high quality synthetic diamond

    Sharp, S.J.


    This thesis is concerned with the study of fundamental and defect induced optical properties of synthetic diamond grown using high pressure, high temperature (HPHT) synthesis or chemical vapour deposition (CVD). The primary technique used for investigation is cathodoluminescence (including imaging and decay-time measurements) in addition to other forms of optical spectroscopy. This thesis is timely in that the crystallinity and purity of synthetic diamond has increased ten fold over the last few years. The diamond exciton emission, which is easily quenched by the presence of defects, is studied in high quality samples in detail. In addition the ability now exists to engineer the isotopic content of synthetic diamond to a high degree of accuracy. The experimental chapters are divided as follows: Chapter 2: High resolution, low temperature spectra reveal a splitting of the free-exciton phonon recombination emission peaks and the bound-exciton zero phonon line. Included are measurements of the variation in intensity and decay-time as a function of temperature. Chapter 3: The shift in energy of the phonon-assisted free-exciton phonon replicas with isotopic content has been measured. The shift is in agreement with the results of interatomic force model for phonon scattering due to isotope disorder. Chapter 4: A study of the shift in energy with isotopic content of the diamond of the GR1 band due to the neutral vacancy has allowed a verification of the theoretical predictions due to the Jahn Teller effect. Chapter 5: The spatial distribution of the free-exciton luminescence is studied in HPHT synthetic and CVD diamond. A variation in intensity with distance from the surface is interpreted as a significant non-radiative loss of excitons to the surface. Chapter 6: The decay-times of all known self-interstitial related centres have been measured in order to calculate the concentration of these centres present in electron irradiated diamond. (author)

  8. High Quality Data for Grid Integration Studies

    Clifton, Andrew; Draxl, Caroline; Sengupta, Manajit; Hodge, Bri-Mathias


    As variable renewable power penetration levels increase in power systems worldwide, renewable integration studies are crucial to ensure continued economic and reliable operation of the power grid. The existing electric grid infrastructure in the US in particular poses significant limitations on wind power expansion. In this presentation we will shed light on requirements for grid integration studies as far as wind and solar energy are concerned. Because wind and solar plants are strongly impacted by weather, high-resolution and high-quality weather data are required to drive power system simulations. Future data sets will have to push limits of numerical weather prediction to yield these high-resolution data sets, and wind data will have to be time-synchronized with solar data. Current wind and solar integration data sets are presented. The Wind Integration National Dataset (WIND) Toolkit is the largest and most complete grid integration data set publicly available to date. A meteorological data set, wind power production time series, and simulated forecasts created using the Weather Research and Forecasting Model run on a 2-km grid over the continental United States at a 5-min resolution is now publicly available for more than 126,000 land-based and offshore wind power production sites. The National Solar Radiation Database (NSRDB) is a similar high temporal- and spatial resolution database of 18 years of solar resource data for North America and India. The need for high-resolution weather data pushes modeling towards finer scales and closer synchronization. We also present how we anticipate such datasets developing in the future, their benefits, and the challenges with using and disseminating such large amounts of data.

  9. Association of a behaviorally based high school health education curriculum with increased exercise.

    Annesi, James J; Trinity, John; Mareno, Nicole; Walsh, Stephanie M


    Increasing exercise in children and adolescents through academic classes is an understudied area. Potential benefits include associated improvements in health, psychosocial, and quality-of-life factors. A sample of 98 students (M(age) = 14.3) from high school health education classes received six, 40-min lessons incorporating cognitive-behavioral methods to increase exercise over 6 weeks. Significant within-group improvements in exercise, mood, and body satisfaction were found, with slightly larger effect sizes identified for the boys. Increase in exercise was significantly associated with reduced mood distress (β = -.17, p goal setting and self-regulation within high school health education classes may foster increased exercise and associated improvements in mood and body satisfaction. For girls, the positive effects may reinforce one another. © The Author(s) 2014.

  12. Constructing the integral concept on the basis of the idea of accumulation: suggestion for a high school curriculum

    Kouropatov, Anatoli; Dreyfus, Tommy


    Students have a tendency to see integral calculus as a series of procedures with associated algorithms and many do not develop a conceptual grasp giving them the desirable versatility of thought. Thus, instead of a proceptual view of the symbols in integration, they have, at best, a process-oriented view. On the other hand, it is not surprising that many students find concepts such as the integral difficult when they are unable to experience these processes directly in the classroom. With a view towards improving this situation, constructing the integral concept on the basis of the idea of accumulation has been proposed (Educ Stud Math. 1994;26:229-274; Integral as accumulation: a didactical perspective for school mathematics; Thessaloniki: PME; 2009. p. 417-424). In this paper, we discuss a curriculum that is based on this idea and a design for curriculum materials that are intended to develop an improved cognitive base for a flexible proceptual understanding of the integral and integration in high school. The main focus is on how we (mathematics teachers and mathematics educators) might teach the integral concept in order to help high school students to construct meaningful knowledge alongside acquiring technical abilities.

  13. Addressing Health Literacy Challenges With a Cutting-Edge Infectious Disease Curriculum for the High School Biology Classroom.

    Jacque, Berri; Koch-Weser, Susan; Faux, Russell; Meiri, Karina


    This study reports the secondary analysis of evaluation data from an innovative high school biology curriculum focused on infectious disease (ID) to examine the health literacy implications of teaching claims evaluation, data interpretation, and risk assessment skills in the context of 21st-Century health science. The curriculum was implemented between 2010 and 2013 in Biology II classes held in four public high schools (three in Massachusetts and one in Ohio), plus a private school in Virginia. A quasi-experimental design was used in which student participants (n = 273) were compared to an age-matched, nonparticipant, peer group (N = 125). Participants in each school setting demonstrated increases in conceptual content knowledge (Cohen's d > 1.89) as well as in understanding how to apply scientific principles to health claims evaluation and risk assessment (Cohen's d > 1.76) and in self-efficacy toward learning about ID (Cohen's d > 2.27). Participants also displayed enhanced communication about ID within their social networks relative to the comparison group (p biology classrooms is effective at fostering both the skills and self-efficacy pertinent to health literacy learning in diverse populations. © 2015 Society for Public Health Education.

  14. Using Evolution as a Context for Teaching the Nature of Science to Diverse Student Populations: A High School Unit of Curriculum

    Metcalfe, Angela C.

    Teaching evolution provides teachers with the opportunity to educate students on how science aims to understand the natural world. Rooted in research, the purpose of this project was to create NGSS-aligned curriculum focused on teaching the nature of science (NOS) within the context of biological evolution. Field testing and review of the unit resulted in revisions aimed at creating more comprehensive teacher resource materials and explicit inclusion of NOS. Emphasizing NOS in curriculum development and teaching scientific qualities through an evolutionary context has taken the focus off belief or disbelief, keeping the attention on the scientific concept at hand. Designing curriculum around compelling subject matter and embracing student-led learning increased and maintained student interest in the classroom. Implementation of this curriculum not only requires the teacher to be knowledgeable in conventional educational pedagogy, but also the subjects of NGSS and NOS. Additional training and support centered around NGSS is recommended for science educators interested in integrating NOS into their curriculum and instruction.

  15. High Efficiency, Illumination Quality OLEDs for Lighting

    Joseph Shiang; James Cella; Kelly Chichak; Anil Duggal; Kevin Janora; Chris Heller; Gautam Parthasarathy; Jeffery Youmans; Joseph Shiang


    The goal of the program was to demonstrate a 45 lumen per watt white light device based upon the use of multiple emission colors through the use of solution processing. This performance level is a dramatic extension of the team's previous 15 LPW large area illumination device. The fundamental material system was based upon commercial polymer materials. The team was largely able to achieve these goals, and was able to deliver to DOE a 90 lumen illumination source that had an average performance of 34 LPW a 1000 cd/m{sup 2} with peak performances near 40LPW. The average color temperature is 3200K and the calculated CRI 85. The device operated at a brightness of approximately 1000cd/m{sup 2}. The use of multiple emission colors particularly red and blue, provided additional degrees of design flexibility in achieving white light, but also required the use of a multilayered structure to separate the different recombination zones and prevent interconversion of blue emission to red emission. The use of commercial materials had the advantage that improvements by the chemical manufacturers in charge transport efficiency, operating life and material purity could be rapidly incorporated without the expenditure of additional effort. The program was designed to take maximum advantage of the known characteristics of these material and proceeded in seven steps. (1) Identify the most promising materials, (2) assemble them into multi-layer structures to control excitation and transport within the OLED, (3) identify materials development needs that would optimize performance within multilayer structures, (4) build a prototype that demonstrates the potential entitlement of the novel multilayer OLED architecture (5) integrate all of the developments to find the single best materials set to implement the novel multilayer architecture, (6) further optimize the best materials set, (7) make a large area high illumination quality white OLED. A photo of the final deliverable is shown

  16. Analysis of high-quality modes in open chaotic microcavities

    Fang, W.; Yamilov, A.; Cao, H.


    We present a numerical study of the high-quality modes in two-dimensional dielectric stadium microcavities. Although the classical ray mechanics is fully chaotic in a stadium billiard, all of the high-quality modes show a 'strong scar' around unstable periodic orbits. When the deformation (ratio of the length of the straight segments over the diameter of the half circles) is small, the high-quality modes correspond to whispering-gallery-type trajectories and their quality factors decrease monotonically with increasing deformation. At large deformation, each high-quality mode is associated with multiple unstable periodic orbits. Its quality factor changes nonmonotonically with the deformation, and there exists an optimal deformation for each mode at which its quality factor reaches a local maximum. This unusual behavior is attributed to the interference of waves propagating along different constituent orbits that could minimize light leakage out of the cavity

  18. Integrating climate-smart rice agriculture into secondary-level curriculum: lessons from three high schools in the Philippines.

    Manalo, Jaime A; Balmeo, Katherine P; Berto, Jayson C; Saludez, Fredierick M; Villaflor, Jennifer D; Pagdanganan, Argie M


    Climate change (CC) is an urgent and highly relevant topic that must be integrated into the school curriculum. Literature on CC integration, however, is scarce, let alone literature on integrating climate-smart rice agriculture (CSRA). Bringing CSRA lessons into the classroom means the chance is higher that climate-smart technologies on rice will reach even the most far-flung areas of the Philippines, which stand to be among the most vulnerable as regards the negative impacts of CC. This paper shares experiences drawn from three high schools in the Philippines on integrating CSRA into their curriculum. The research centers on appropriate teaching tools/strategies, push and exogenous factors in CSRA integration, and the types of information that are likely to be shared by the students with their farmer-parents or other farmers in their communities. Surveys among participating students (n = 155) and three focus group discussions among key school officials were conducted. Different teaching methods and/or tools were found to be generally useful in various contexts. Photos and videos, however, emerged as the most effective tools across sites. The livelihood source of the students does have a bearing on the complexity of messages that they can convey. Students from rice-farming households can competently discuss even highly complex adaptation and mitigation information with their farmer-parents or other farmers. Thorough message-framing is necessary to maximize student involvement as well as to increase production of education-entertainment (edutainment) materials to be utilized in teaching. This study, in general, contributes to CC education by bringing in best-fit practices in teaching tools and strategies to mobilize students to act on urgent matters relating to the impacts of CC. It also advises on considering exogenous factors that might affect CC education by taking into account those that are equally capable of shaping students' perception and knowledge.

  19. Teaching Astronomy and Computation with Gaia: A New Curriculum for an Extra-curricular High School Program

    Schwab, Ellianna; Faherty, Jacqueline K.; Barua, Prachurjya; Cooper, Ellie; Das, Debjani; Simone-Gonzalez, Luna; Sowah, Maxine; Valdez, Laura; BridgeUP: STEM


    BridgeUP: STEM (BridgeUP) is a program at the American Museum of Natural History (AMNH) that seeks to empower women by providing early-career scientists with research fellowships and high-school aged women with instruction in computer science and algorithmic methods. BridgeUP achieves this goal by employing post-baccalaureate women as Helen Fellows, who, in addition to conducting their own scientific research, mentor and teach high school students from the New York City area. The courses, targeted at early high-school students, are designed to teach algorithmic thinking and scientific methodology through the lens of computational science. In this poster we present the new BridgeUP astronomy curriculum created for 9th and 10th grade girls.The astronomy course we present is designed to introduce basic concepts as well as big data manipulation through a guided exploration of Gaia (DR1). Students learn about measuring astronomical distances through hands-on lab experiments illustrating the brightness/distance relationship, angular size calculations of the height of AMNH buildings, and in-depth Hertzsprung-Russell Diagram activities. Throughout these labs, students increase their proficiency in collecting and analyzing data, while learning to build and share code in teams. The students use their new skills to create color-color diagrams of known co-moving clusters (Oh et al. 2017) in the DR1 dataset using Python, Pandas and Matplotlib. We discuss the successes and lessons learned in the first implementation of this curriculum and show the preliminary work of six of the students, who are continuing with computational astronomy research over the current school year.

  3. Creating a National HIV Curriculum.

    Spach, David H; Wood, Brian R; Karpenko, Andrew; Unruh, Kenton T; Kinney, Rebecca G; Roscoe, Clay; Nelson, John


    In recent years, the HIV care provider workforce has not kept pace with an expanding HIV epidemic. To effectively address this HIV workforce shortage, a multipronged approach is needed that includes high-quality, easily accessible, up-to-date HIV education for trainees and practicing providers. Toward this objective, the University of Washington, in collaboration with the AIDS Education and Training Center National Coordinating Resource Center, is developing a modular, dynamic curriculum that addresses the entire spectrum of the HIV care continuum. Herein, we outline the general principles, content, organization, and features of this federally funded National HIV Curriculum, which allows for longitudinal, active, self-directed learning, as well as real-time evaluation, tracking, and feedback at the individual and group level. The online curriculum, which is in development, will provide a free, comprehensive, interactive HIV training and resource tool that can support national efforts to expand and strengthen the United States HIV clinical care workforce.

  16. Short-term effects of a rights-based sexuality education curriculum for high-school students: a cluster-randomized trial.

    Constantine, Norman A; Jerman, Petra; Berglas, Nancy F; Angulo-Olaiz, Francisca; Chou, Chih-Ping; Rohrbach, Louise A


    An emerging model for sexuality education is the rights-based approach, which unifies discussions of sexuality, gender norms, and sexual rights to promote the healthy sexual development of adolescents. A rigorous evaluation of a rights-based intervention for a broad population of adolescents in the U.S. has not previously been published. This paper evaluates the immediate effects of the Sexuality Education Initiative (SEI) on hypothesized psychosocial determinants of sexual behavior. A cluster-randomized trial was conducted with ninth-grade students at 10 high schools in Los Angeles. Classrooms at each school were randomized to receive either a rights-based curriculum or basic sex education (control) curriculum. Surveys were completed by 1,750 students (N = 934 intervention, N = 816 control) at pretest and immediate posttest. Multilevel regression models examined the short-term effects of the intervention on nine psychosocial outcomes, which were hypothesized to be mediators of students' sexual behaviors. Compared with students who received the control curriculum, students receiving the rights-based curriculum demonstrated significantly greater knowledge about sexual health and sexual health services, more positive attitudes about sexual relationship rights, greater communication about sex and relationships with parents, and greater self-efficacy to manage risky situations at immediate posttest. There were no significant differences between the two groups for two outcomes, communication with sexual partners and intentions to use condoms. Participation in the rights-based classroom curriculum resulted in positive, statistically significant effects on seven of nine psychosocial outcomes, relative to a basic sex education curriculum. Longer-term effects on students' sexual behaviors will be tested in subsequent analyses. NCT02009046.

  19. Quack: A quality assurance tool for high throughput sequence data.

    Thrash, Adam; Arick, Mark; Peterson, Daniel G


    The quality of data generated by high-throughput DNA sequencing tools must be rapidly assessed in order to determine how useful the data may be in making biological discoveries; higher quality data leads to more confident results and conclusions. Due to the ever-increasing size of data sets and the importance of rapid quality assessment, tools that analyze sequencing data should quickly produce easily interpretable graphics. Quack addresses these issues by generating information-dense visualizations from FASTQ files at a speed far surpassing other publicly available quality assurance tools in a manner independent of sequencing technology.

  18. High quality, high efficiency welding technology for nuclear power plants

    Aoki, Shigeyuki; Nagura, Yasumi


    For nuclear power plants, it is required to ensure the safety under the high reliability and to attain the high rate of operation. In the manufacture and installation of the machinery and equipment, the welding techniques which become the basis exert large influence to them. For the purpose of improving joint performance and excluding human errors, welding heat input and the number of passes have been reduced, the automation of welding has been advanced, and at present, narrow gap arc welding and high energy density welding such as electron beam welding and laser welding have been put to practical use. Also in the welding of pipings, automatic gas metal arc welding is employed. As for the welding of main machinery and equipment, there are the welding of the joints that constitute pressure boundaries, the build-up welding on the internal surfaces of pressure vessels for separating primary water from them, and the sealing welding of heating tubes and tube plates in steam generators. These weldings are explained. The welding of pipings and the state of development and application of new welding methods are reported. (K.I.)

  19. Concrete Waste Recycling Process for High Quality Aggregate

    Ishikura, Takeshi; Fujii, Shin-ichi


    Large amount of concrete waste generates during nuclear power plant (NPP) dismantling. Non-contaminated concrete waste is assumed to be disposed in a landfill site, but that will not be the solution especially in the future, because of decreasing tendency of the site availability and natural resources. Concerning concrete recycling, demand for roadbeds and backfill tends to be less than the amount of dismantled concrete generated in a single rural site, and conventional recycled aggregate is limited of its use to non-structural concrete, because of its inferior quality to ordinary natural aggregate. Therefore, it is vital to develop high quality recycled aggregate for general uses of dismantled concrete. If recycled aggregate is available for high structural concrete, the dismantling concrete is recyclable as aggregate for industry including nuclear field. Authors developed techniques on high quality aggregate reclamation for large amount of concrete generated during NPP decommissioning. Concrete of NPP buildings has good features for recycling aggregate; large quantity of high quality aggregate from same origin, record keeping of the aggregate origin, and little impurities in dismantled concrete such as wood and plastics. The target of recycled aggregate in this development is to meet the quality criteria for NPP concrete as prescribed in JASS 5N 'Specification for Nuclear Power Facility Reinforced Concrete' and JASS 5 'Specification for Reinforced Concrete Work'. The target of recycled aggregate concrete is to be comparable performance with ordinary aggregate concrete. The high quality recycled aggregate production techniques are assumed to apply for recycling for large amount of non-contaminated concrete. These techniques can also be applied for slightly contaminated concrete dismantled from radiological control area (RCA), together with free release survey. In conclusion: a technology on dismantled concrete recycling for high quality aggregate was developed

  20. High-quality planar high-Tc Josephson junctions

    Bergeal, N.; Grison, X.; Lesueur, J.; Faini, G.; Aprili, M.; Contour, J.P.


    Reproducible high-T c Josephson junctions have been made in a rather simple two-step process using ion irradiation. A microbridge (1 to 5 μm wide) is firstly designed by ion irradiating a c-axis-oriented YBa 2 Cu 3 O 7-δ film through a gold mask such as the nonprotected part becomes insulating. A lower T c part is then defined within the bridge by irradiating with a much lower fluence through a narrow slit (20 nm) opened in a standard electronic photoresist. These planar junctions, whose settings can be finely tuned, exhibit reproducible and nearly ideal Josephson characteristics. This process can be used to produce complex Josephson circuits

  4. Sports Cardiology: Core Curriculum for Providing Cardiovascular Care to Competitive Athletes and Highly Active People.

    Baggish, Aaron L; Battle, Robert W; Beckerman, James G; Bove, Alfred A; Lampert, Rachel J; Levine, Benjamin D; Link, Mark S; Martinez, Matthew W; Molossi, Silvana M; Salerno, Jack; Wasfy, Meagan M; Weiner, Rory B; Emery, Michael S


    The last few decades have seen substantial growth in the populations of competitive athletes and highly active people (CAHAP). Although vigorous physical exercise is an effective way to reduce the risk of cardiovascular (CV) disease, CAHAP remain susceptible to inherited and acquired CV disease, and may be most at risk for adverse CV outcomes during intense physical activity. Traditionally, multidisciplinary teams comprising athletic trainers, physical therapists, primary care sports medicine physicians, and orthopedic surgeons have provided clinical care for CAHAP. However, there is increasing recognition that a care team including qualified CV specialists optimizes care delivery for CAHAP. In recognition of the increasing demand for CV specialists competent in the care of CAHAP, the American College of Cardiology has recently established a Sports and Exercise Council. An important primary objective of this council is to define the essential skills necessary to practice effective sports cardiology. Copyright © 2017. Published by Elsevier Inc.

  5. A comparative analysis of Science-Technology-Society standards in elementary, middle and high school state science curriculum frameworks

    Tobias, Karen Marie

    An analysis of curriculum frameworks from the fifty states to ascertain the compliance with the National Science Education Standards for integrating Science-Technology-Society (STS) themes is reported within this dissertation. Science standards for all fifty states were analyzed to determine if the STS criteria were integrated at the elementary, middle, and high school levels of education. The analysis determined the compliance level for each state, then compared each educational level to see if the compliance was similar across the levels. Compliance is important because research shows that using STS themes in the science classroom increases the student's understanding of the concepts, increases the student's problem solving skills, increases the student's self-efficacy with respect to science, and students instructed using STS themes score well on science high stakes tests. The two hypotheses for this study are: (1) There is no significant difference in the degree of compliance to Science-Technology-Society themes (derived from National Science Education Standards) between the elementary, middle, and high school levels. (2) There is no significant difference in the degree of compliance to Science-Technology-Society themes (derived from National Science Education Standards) between the elementary, middle, and high school level when examined individually. The Analysis of Variance F ratio was used to determine the variance between and within the three educational levels. This analysis addressed hypothesis one. The Analysis of Variance results refused to reject the null hypothesis, meaning there is significant difference in the compliance to STS themes between the elementary, middle and high school educational levels. The Chi-Square test was the statistical analysis used to compare the educational levels for each individual criterion. This analysis addressed hypothesis two. The Chi-Squared results showed that none of the states were equally compliant with each

  6. CESAME: Providing High Quality Professional Development in Science and Mathematics for K-12 Teachers

    Hickman, Paul


    It is appropriate that after almost half a century of Science and Mathematics education reform we take a look back and a peek forward to understand the present state of this wonderfully complex system. Each of the components of this system including teaching, professional development, assessment, content and the district K-12 curriculum all need to work together if we hope to provide quality science, mathematics and technology education for ALL students. How do the state and national standards drive the system? How do state policies on student testing and teacher licensure come into play? How do we improve the preparation, retention and job satisfaction of our K-12 teachers? What initiatives have made or are making a difference? What else needs to be done? What can the physics community do to support local efforts? This job is too big for any single organization or individual but we each can contribute to the effort. Our Center at Northeastern University, with support from the National Science Foundation, has a sharply defined focus: to get high quality, research-based instructional materials into the hands of K-12 classroom teachers and provide the support they need to use the materials effectively in their classrooms.

  7. High-quality cardiopulmonary resuscitation: current and future directions.

    Abella, Benjamin S


    Cardiopulmonary resuscitation (CPR) represents the cornerstone of cardiac arrest resuscitation care. Prompt delivery of high-quality CPR can dramatically improve survival outcomes; however, the definitions of optimal CPR have evolved over several decades. The present review will discuss the metrics of CPR delivery, and the evidence supporting the importance of CPR quality to improve clinical outcomes. The introduction of new technologies to quantify metrics of CPR delivery has yielded important insights into CPR quality. Investigations using CPR recording devices have allowed the assessment of specific CPR performance parameters and their relative importance regarding return of spontaneous circulation and survival to hospital discharge. Additional work has suggested new opportunities to measure physiologic markers during CPR and potentially tailor CPR delivery to patient requirements. Through recent laboratory and clinical investigations, a more evidence-based definition of high-quality CPR continues to emerge. Exciting opportunities now exist to study quantitative metrics of CPR and potentially guide resuscitation care in a goal-directed fashion. Concepts of high-quality CPR have also informed new approaches to training and quality improvement efforts for cardiac arrest care.

  10. The High School Physics Curriculum and the University of North Dakota Observatory

    Nolby, C.; Hardersen, P.


    As astronomy is a subject largely absent in the secondary classroom for many reasons, the research presented here attempts to make astronomy education an option for high school students across the state of North Dakota. Through implementation of a two-week astronomy course at Grand Forks Central High School (GFCHS), two class periods totaling nineteen physics students (fourteen in the first class period and five in the second class period) were given the opportunity to learn material that would have otherwise been unavailable to them. Four of these students were female and fifteen of these students were male. During ten class periods from April 16, 2012 through April 27, 2012, instruction included presentation of basic astronomy concepts and observational techniques as well as student participation in demonstrations and activities regarding the course content. Students were given the option to visit the University of North Dakota (UND) Observatory the evening of April 20, 2012 for a public “star party” where they received a tour of the university's telescopes and other research equipment. During class time on April 25, 2012, students took a field trip to the John D. Odegard School of Aerospace Sciences to tour both Aviation and Space Studies facilities at UND. The lesson plan for the course also included a group project utilizing the telescopes at the UND Observatory for remote observing to complete research on the astrometry of an asteroid. Students were given a pre-test at the start of the two-week course, daily exit surveys at the end of each class period, and a post-test at the end of the two-week course. These assessments were used to evaluate student enjoyment, progress, and overall perception of the astronomy course. This research identified common misconceptions in astronomy held by the learners as well as the most effective teaching methods. It was found that this course was overall successful in promoting the students' learning of astronomy in a short

  4. Methods and systems for fabricating high quality superconducting tapes

    Majkic, Goran; Selvamanickam, Venkat


    An MOCVD system fabricates high quality superconductor tapes with variable thicknesses. The MOCVD system can include a gas flow chamber between two parallel channels in a housing. A substrate tape is heated and then passed through the MOCVD housing such that the gas flow is perpendicular to the tape's surface. Precursors are injected into the gas flow for deposition on the substrate tape. In this way, superconductor tapes can be fabricated with variable thicknesses, uniform precursor deposition, and high critical current densities.

  6. The perceptions and practices of selected high school teachers in special admission schools regarding writing across the curriculum

    Mitchell, Rebecca Hayward

    The National Assessment of Educational Progress (NAEP) measured the writing achievement of 55,000 American school children. The students performed at the basic or lower level. In 1988, "The Writing Report Card of the NAEP," and in 1996, the Pennsylvania Mathematics and Reading Assessment along with the Stanford 9 Exam concluded that students, of all racial/ethnic backgrounds, are unable to write well except in response to the simplest tasks. The purpose of this study was to determine the perceptions and practices of math, science, and social studies high school teachers in special admission schools regarding writing across the curriculum (WAC). Specifically, this study attempted to answer: (1) Do math, science, and social studies teachers differ in their perceptions and practices regarding student writing in their classrooms? (2) Are teacher characteristics related to the perceptions and practices of math, science, and social studies teachers regarding the need for student writing in their classrooms? The questions led to the following null hypotheses: (1) There is no significant difference among math, science, and social studies teachers regarding their perceptions and practices for student writing in their classrooms. (2) There is no significant relationship between the highest degree earned, the length of teaching experience, and the level of grades taught by math, science, and social studies teachers and their perceptions and practices regarding the need for student writing in their classrooms. A review of the literature since 1992 using ERIC and Dissertation Abstracts revealed that there were no studies concerned with the focus of this particular study. A cross sectional survey of School District of Philadelphia math, science, and social studies high school teachers in special admission schools was conducted. A questionnaire was developed to obtain the data. A panel of experts was selected to establish validity of the instrument. Thirty-two usable

  7. [Quality of sleep and academic performance in high school students].

    Bugueño, Maithe; Curihual, Carolina; Olivares, Paulina; Wallace, Josefa; López-AlegrÍa, Fanny; Rivera-López, Gonzalo; Oyanedel, Juan Carlos


    Sleeping and studying are the day-to-day activities of a teenager attending school. To determine the quality of sleep and its relationship to the academic performance among students attending morning and afternoon shifts in a public high school. Students of the first and second year of high school answered an interview about socio-demographic background, academic performance, student activities and subjective sleep quality; they were evaluated using the Pittsburgh Sleep Quality Index (PSQI). The interview was answered by 322 first year students aged 15 ± 5 years attending the morning shift and 364 second year students, aged 16 ± 0.5 years, attending the afternoon shift. The components: sleep latency, habitual sleep efficiency, sleep disturbance, drug use and daytime dysfunction were similar and classified as good in both school shifts. The components subjective sleep quality and duration of sleep had higher scores among students of the morning shift. The mean grades during the first semester of the students attending morning and afternoon shifts were 5.9 and 5.8, respectively (of a scale from 1 to 7). Among students of both shifts, the PSQI scale was associated inversely and significantly with academic performance. A bad sleep quality influences academic performance in these students.

  8. Highly qualified does not equal high quality: A study of urban stakeholders' perceptions of quality in science teaching

    Miranda, Rommel Joseph

    By employing qualitative methods, this study sought to determine the perceptions that urban stakeholders hold about what characteristics should distinguish a high school science teacher whom they would consider to demonstrate high quality in science teaching. A maximum variation sample of six science teachers, three school administrators, six parents and six students from a large urban public school district were interviewed using semi-structured, in-depth interview techniques. From these data, a list of observable characteristics which urban stakeholders hold as evidence of high quality in science teaching was generated. Observational techniques were utilized to determine the extent to which six urban high school science teachers, who meet the NCLB Act criteria for being "highly qualified", actually possessed the characteristics which these stakeholders hold as evidence of high quality in science teaching. Constant comparative analysis was used to analyze the data set. The findings suggest that urban stakeholders perceive that a high school science teacher who demonstrates high quality in science teaching should be knowledgeable about their subject matter, their student population, and should be resourceful; should possess an academic background in science and professional experience in science teaching; should exhibit professionalism, a passion for science and teaching, and a dedication to teaching and student learning; should be skillful in planning and preparing science lessons and in organizing the classroom, in presenting the subject matter to students, in conducting a variety of hands-on activities, and in managing a classroom; and should assess whether students complete class goals and objectives, and provide feedback about grades for students promptly. The findings further reveal that some of the urban high school science teachers who were deemed to be "highly qualified", as defined by the NCLB Act, engaged in practices that threatened quality in science

  9. High quality digital holographic reconstruction on analog film

    Nelsen, B.; Hartmann, P.


    High quality real-time digital holographic reconstruction, i.e. at 30 Hz frame rates, has been at the forefront of research and has been hailed as the holy grail of display systems. While these efforts have produced a fascinating array of computer algorithms and technology, many applications of reconstructing high quality digital holograms do not require such high frame rates. In fact, applications such as 3D holographic lithography even require a stationary mask. Typical devices used for digital hologram reconstruction are based on spatial-light-modulator technology and this technology is great for reconstructing arbitrary holograms on the fly; however, it lacks the high spatial resolution achievable by its analog counterpart, holographic film. Analog holographic film is therefore the method of choice for reconstructing highquality static holograms. The challenge lies in taking a static, high-quality digitally calculated hologram and effectively writing it to holographic film. We have developed a theoretical system based on a tunable phase plate, an intensity adjustable high-coherence laser and a slip-stick based piezo rotation stage to effectively produce a digitally calculated hologram on analog film. The configuration reproduces the individual components, both the amplitude and phase, of the hologram in the Fourier domain. These Fourier components are then individually written on the holographic film after interfering with a reference beam. The system is analogous to writing angularly multiplexed plane waves with individual component phase control.

  10. Long quantum channels for high-quality entanglement transfer

    Banchi, L; Apollaro, T J G; Cuccoli, A; Verrucchi, P; Vaia, R


    High-quality quantum-state and entanglement transfer can be achieved in an unmodulated spin bus operating in the ballistic regime, which occurs when the endpoint qubits A and B are nonperturbatively coupled to the chain by a suitable exchange interaction j 0 . Indeed, the transition amplitude characterizing the transfer quality exhibits a maximum for a finite optimal value j opt 0 (N), where N is the channel length. We show that j opt 0 (N) scales as N -1/6 for large N and that it ensures a high-quality entanglement transfer even in the limit of arbitrarily long channels, almost independently of the channel initialization. For instance, for any chain length the average quantum-state transmission fidelity exceeds 90% and decreases very little in a broad neighbourhood of j opt 0 (N). We emphasize that, taking the reverse point of view, should j 0 be experimentally constrained, high-quality transfer can still be obtained by adjusting the channel length to its optimal value.

  13. Quality and efficiency in high dimensional Nearest neighbor search

    Tao, Yufei; Yi, Ke; Sheng, Cheng; Kalnis, Panos


    Nearest neighbor (NN) search in high dimensional space is an important problem in many applications. Ideally, a practical solution (i) should be implementable in a relational database, and (ii) its query cost should grow sub-linearly with the dataset size, regardless of the data and query distributions. Despite the bulk of NN literature, no solution fulfills both requirements, except locality sensitive hashing (LSH). The existing LSH implementations are either rigorous or adhoc. Rigorous-LSH ensures good quality of query results, but requires expensive space and query cost. Although adhoc-LSH is more efficient, it abandons quality control, i.e., the neighbor it outputs can be arbitrarily bad. As a result, currently no method is able to ensure both quality and efficiency simultaneously in practice. Motivated by this, we propose a new access method called the locality sensitive B-tree (LSB-tree) that enables fast highdimensional NN search with excellent quality. The combination of several LSB-trees leads to a structure called the LSB-forest that ensures the same result quality as rigorous-LSH, but reduces its space and query cost dramatically. The LSB-forest also outperforms adhoc-LSH, even though the latter has no quality guarantee. Besides its appealing theoretical properties, the LSB-tree itself also serves as an effective index that consumes linear space, and supports efficient updates. Our extensive experiments confirm that the LSB-tree is faster than (i) the state of the art of exact NN search by two orders of magnitude, and (ii) the best (linear-space) method of approximate retrieval by an order of magnitude, and at the same time, returns neighbors with much better quality. © 2009 ACM.

    Jeanine Siebold


    Full Text Available Four sections of senior Honors Human Anatomy and Physiology (A&P students are representative of sixty-five nations. These classes participated in a yearlong investigation pursuant of innovative learning, and grading modalities to introduce a 21st century curriculum for A&P to become a College Board Advanced Placement (AP course. All enrollees began the year by taking a self-assessment based on Howard Gardner's Multiple Intelligences. This data was evaluated for the design of learning approaches identifying student uniqueness that could better implement the Next Generation Science Standards (NGSS, and present State of Tennessee Human Anatomy and Physiology Learning Standards laying the groundwork to write the AP curriculum. Component curriculum rubrics were used, and modified to enable students to self-evaluate their performance in certain areas. Students participated in teams represented as Center for Disease Control and Prevention (CDC 'Intern Teams' investigating various diseases. The students, also, researched health equity, and disparity issues from variables based on survey questions they designed that could affect the health care treatment of patients suffering from their investigated disease.

  15. 教師理解與課程發展:另類高中科學課程評鑑之個案研究Teacher Understanding and Curriculum Development: An Alternative Approach of Curriculum Evaluation of A Science High School

    高熏芳Hsun-Fung Kitty Kao


    於他人與自我的理解:1.教師認為學生缺乏「新興科學技術」的先備知識,而大部分的家長只關心學生的升學;2.教師認為同儕對話與校內發表,可以幫助自我反思與提供課程修訂的機會。(三)教師對於課程發展環境的理解:1.教師認為應該以「由下而上」的素材發展取代「由上而下」的課程發展;2.教師認為學校的定位為科學高中,理應以「新興科學技術」為主,來進行課程發展;3.教師認為學校課程發展的條件與理由,不能成為其課程發展強而有力的支持。本研究結果期望提供其他課程發展與教學者,從不同的角度去觀察與解釋課程評鑑,並擴大其對於課程的瞭解,以獲得更好的課程與教學品質。 In order to enhance the learning of emergent science and technology at Taiwan, the Department of Science Education in National Science Council initiated a so called “Project of High Scope” since 2005. It emphasizes the establishment of the partnership between senior high schools and universities or research organizations to improve the quality of teaching in science through the development of new school-based curriculum. The school-based curriculum is intended to actively promote the “bottom up” curriculum development model which empowers teachers to work out professional autonomy. However, in order to reduce the gap between theory and practice, it is expected that teachers can deeply theorize the purposes of curriculum and actualize their ideal of instruction by themselves. The purpose of this study is to investigate teachers’ belief and value of the curriculum as well as their understanding of the curriculum development. The study looks into teachers understanding of curriculum content, curriculum development process, teacher self vs. students, as well as the school context. The study applies case study techniques such as observation, interview and archive analysis to come to a holistic

    Appelbloom, A.M.; Hadley, P.; van der Marel, D.; Mooij, J.E.


    This paper reports on a high quality flux control system for electron gun evaporation developed and tested for the MBE growth of high temperature superconductors. The system can be applied to any electron gun without altering the electron gun itself. Essential elements of the system are a high bandwidth mass spectrometer, control electronics and a high voltage modulator to sweep the electron beam over the melt at high frequencies. the sweep amplitude of the electron beam is used to control the evaporation flux at high frequencies. The feedback loop of the system has a bandwidth of over 100 Hz, which makes it possible to grow superlattices and layered structures in a fast and precisely controlled manner

  17. Curriculum enactment patterns and associated factors from teachers' perspectives

    Son, Ji-Won; Kim, Ok-Kyeong


    As part of a larger effort to improve teacher capacity for high-quality mathematics instruction, we investigated the factors that are associated with different enactment patterns at three levels: contextual (e.g., type and quality of textbook), individual (e.g., teacher knowledge), and teachers' opportunity-to-learn (e.g., professional development experiences). Analysis of 183 teachers' self-reports on their practices revealed three notable findings. First, the factors at the three levels were all found to be significantly related to the different patterns of enacted curriculum. However, the use of quality textbooks and the alignment of teachers' views and instructional goals with curriculum goals were found to be the two factors that are most strongly associated with the enactment pattern of high-level problems and high-level teacher questions in instruction. Furthermore, teachers with the enactment pattern of increasing lower cognitive demand of problems into higher ones tended to rate their curriculum knowledge higher than teachers with the enactment pattern of using low-level problems and teacher questions in their teaching. In particular, deviation from and dissatisfaction with their assigned low-quality textbooks were found to be critical factors that are associated with the enactment pattern of increasing lower cognitive demands of problems in instruction.

  19. Safety and quality management at the high flux reactor Petten

    Zurita, A.; Ahlf, J.


    The High Flux Reactor (HFR) is one high power multi-purpose materials testing research reactor of the tank-in-pool type, cooled and moderated by light-water. It is operated at 45 MW at a prescribed schedule of 11 cycles per year, each comprising 25 operation days and three shut-down days. Since the licence for the operation of HFR was granted in 1962, a total of 14 amendments to the original licence have been made following different modifications in the installations. In the meantime, international nuclear standards were developed, especially in the framework of the NUSS programme of the IAEA, which were adopted by the Dutch Licensing Authorities. In order to implement the new standards, the situation at the HFR was comprehensively reviewed in the course of an audit performed by the Dutch Licensing Authorities in 1988. This also resulted in formulating the task of setting-up an 'HFR - Integral Quality Assurance Handbook' (HFR-IQAD) involving both organizations JRCIAM and ECN, which had the unique framework and basic guideline to assure the safe and efficient operation and exploitation of the HFR and to promote safety and quality in all aspects of HFR related activities. The assurance of safe and efficient operation and exploitation of the HFR is condensed together under the concepts of safety and quality of services and is achieved through the safety and quality management.

  20. Evaluating the Effects of Medical Explorers a Case Study Curriculum on Critical Thinking, Attitude Toward Life Science, and Motivational Learning Strategies in Rural High School Students

    Brand, Lance G.


    The purpose of this study was three-fold: to measure the ability of the Medical Explorers case-based curriculum to improve higher order thinking skills; to evaluate the impact of the Medical Explorers case-based curriculum to help students be self directed learners; and to investigate the impact of the Medical Explorers case-based curriculum to improve student attitudes of the life sciences. The target population for this study was secondary students enrolled in advanced life science programs. The resulting sample (n = 71) consisted of 36 students in the case-based experimental group and 35 students in the control group. Furthermore, this study employed an experimental, pretest-posttest control group research design. The treatment consisted of two instructional strategies: case-based learning and teacher-guided learning. Analysis of covariance indicated no treatment effect on critical thinking ability or Motivation and Self-regulation of Learning. However, the Medical Explorers case-based curriculum did show a treatment effect on student attitudes toward the life sciences. These results seem to indicate that case-based curriculum has a positive impact on students' perspectives and attitudes about the study of life science as well as their interest in life science based careers. Such outcomes are also a good indicator that students enjoy and perceive the value to use of case studies in science, and because they see value in the work that they do they open up their minds to true learning and integration. Of additional interest was the observationthat on average eleventh graders showed consistently stronger gains in critical thinking, motivation and self-regulation of learning strategies, and attitudes toward the life sciences as compared to twelfth grade students. In fact, twelfth grade students showed a pre to post loss on the Watson-Glaser and the MSLQ scores while eleventh grade students showed positive gains on each of these instruments. This decline in twelfth

    during runoff events. Engaging students year-round has a number of benefits, including continuity with community partners, being able to assess seasonal controls in water-quality dynamics and to capture significant runoff events, and exposing students to different aspects of the complex system over time. Supporting such student engagement is costly in terms of instructor time, especially for introductory students, who collect enough data to feel “ownership” but are provided with additional data so as to have an adequate basis for conclusions relevant to stakeholders. Strategies for providing these additional data include (1) regular (e.g., weekly) “snapshot sampling” by undergraduate interns, and (2) automated dataloggers and samplers obtained from external funding for curriculum development. Students assume increasing independence and time commitment to the project as they progress through the curriculum, building upon their prior experiences. Along the way, they learn authentic lessons both on how scientific knowledge is developed, and on how that knowledge is communicated to the benefit of diverse stakeholders in the community.

  2. Wellbeing Understanding in High Quality Healthcare Informatics and Telepractice.

    Fiorini, Rodolfo A; De Giacomo, Piero; L'Abate, Luciano


    The proper use of healthcare informatics technology and multidimensional conceptual clarity are fundamental to create and boost outstanding clinical and telepractice results. Avoiding even terminology ambiguities is mandatory for high quality of care service. For instance, well-being or wellbeing is a different way to write the same concept only, or there is a good deal of ambiguity around the meanings of these terms the way they are written. In personal health, healthcare and healthcare informatics, this kind of ambiguity and lack of conceptual clarity has been called out repeatedly over the past 50 years. It is time to get the right, terse scenario. We present a brief review to develop and achieve ultimate wellbeing understanding for practical high quality healthcare informatics and telepractice application. This article presents an innovative point of view on deeper wellbeing understanding towards its increased clinical effective application.

  3. Applying the concept of quality of life to Israeli special education programs: a national curriculum for enhanced autonomy in students with special needs.

    Reiter, Shunit; Schalock, Robert L


    This study provides a description of the design and development of guidelines and programs for a national core curriculum for special education in Israel. Israel was exposed during the 1970s to the ideology of normalization. Later on, toward the end of the 1980s, the concept of quality of life was added. Several research studies were conducted, resulting in the following core ideas about education: a shift of emphasis from teaching independent-living skills to teaching autonomy, self-awareness, self-direction, and interdependence is required. On the basis of these ideas, a new model of instruction was devised and termed the 'cycle of internalized learning' (CIL). The CIL is based on a holistic orientation toward the student and builds on abilities rather than disabilities. The peer group is the basic unit of instruction. Attention is on processes and outcomes. The CIL involves several clearly defined teaching steps: (i) opening--the presentation of the subject matter; (ii) discussion--a conceptual analysis of the subject; (iii) open conversation--students discuss the issues they raised during the first session, express their personal life experiences while applying the new concepts they learned, and suggest possible solutions to problems; (iv) trying out the solutions suggested by students; and (v) repeated discussions, to arrive at personal and social conclusions. Currently there are three published units of the CIL: (i) Social Education, (ii) Career Education, and (iii) Towards Leaving Home for Independent Living in the Community. The fourth unit, on citizenship education through the use of computers, is in its final stages of preparation. The success of the implementation of the program is expressed both at the students' level--as an enhanced sense of self-worth and self-confidence, as well as enhanced academic achievements and social skills--and at the teachers' level--as a paradigm shift from a medical model of approach to students with disabilities to a

    Lock, Evgeniya H; Baraket, Mira; Laskoski, Matthew; Mulvaney, Shawn P; Lee, Woo K; Sheehan, Paul E; Hines, Daniel R; Robinson, Jeremy T; Tosado, Jacob; Fuhrer, Michael S; Hernández, Sandra C; Walton, Scott G


    In this paper we demonstrate high-quality, uniform dry transfer of graphene grown by chemical vapor deposition on copper foil to polystyrene. The dry transfer exploits an azide linker molecule to establish a covalent bond to graphene and to generate greater graphene-polymer adhesion compared to that of the graphene-metal foil. Thus, this transfer approach provides a novel alternative route for graphene transfer, which allows for the metal foils to be reused. © 2011 American Chemical Society

  7. A high throughput DNA extraction method with high yield and quality

    Xin Zhanguo


    Full Text Available Abstract Background Preparation of large quantity and high quality genomic DNA from a large number of plant samples is a major bottleneck for most genetic and genomic analyses, such as, genetic mapping, TILLING (Targeting Induced Local Lesion IN Genome, and next-generation sequencing directly from sheared genomic DNA. A variety of DNA preparation methods and commercial kits are available. However, they are either low throughput, low yield, or costly. Here, we describe a method for high throughput genomic DNA isolation from sorghum [Sorghum bicolor (L. Moench] leaves and dry seeds with high yield, high quality, and affordable cost. Results We developed a high throughput DNA isolation method by combining a high yield CTAB extraction method with an improved cleanup procedure based on MagAttract kit. The method yielded large quantity and high quality DNA from both lyophilized sorghum leaves and dry seeds. The DNA yield was improved by nearly 30 fold with 4 times less consumption of MagAttract beads. The method can also be used in other plant species, including cotton leaves and pine needles. Conclusion A high throughput system for DNA extraction from sorghum leaves and seeds was developed and validated. The main advantages of the method are low cost, high yield, high quality, and high throughput. One person can process two 96-well plates in a working day at a cost of $0.10 per sample of magnetic beads plus other consumables that other methods will also need.

  8. Methods and systems for fabricating high quality superconducting tapes

    Majkic, Goran; Selvamanickam, Venkat


    An MOCVD system fabricates high quality superconductor tapes with variable thicknesses. The MOCVD system can include a gas flow chamber between two parallel channels in a housing. A substrate tape is heated and then passed through the MOCVD housing such that the gas flow is perpendicular to the tape's surface. Precursors are injected into the gas flow for deposition on the substrate tape. In this way, superconductor tapes can be fabricated with variable thicknesses, uniform precursor deposition, and high critical current densities.

  9. High quality mask storage in an advanced Logic-Fab

    Jähnert, Carmen; Fritsche, Silvio


    High efficient mask logistics as well as safe and high quality mask storage are essential requirements within an advanced lithography area of a modern logic waferfab. Fast operational availability of the required masks at the exposure tool with excellent mask condition requires a safe mask handling, safeguarding of high mask quality over the whole mask usage time without any quality degradation and an intelligent mask logistics. One big challenge is the prevention of haze on high advanced phase shift masks used in a high volume production line for some thousands of 248nm or 193nm exposures. In 2008 Infineon Dresden qualified a customer specific developed semi-bare mask storage system from DMSDynamic Micro Systems in combination with a high advanced mask handling and an interconnected complex logistic system. This high-capacity mask storage system DMS M1900.22 for more than 3000 masks with fully automated mask and box handling as well as full-blown XCDA purge has been developed and adapted to the Infineon Lithotoollandscape using Nikon and SMIF reticle cases. Advanced features for ESD safety and mask security, mask tracking via RFID and interactions with the exposure tools were developed and implemented. The stocker is remote controlled by the iCADA-RSM system, ordering of the requested mask directly from the affected exposure tool allows fast access. This paper discusses the advantages and challenges for this approach as well as the practical experience gained during the implementation of the new system which improves the fab performance with respect to mask quality, security and throughput. Especially the realization of an extremely low and stable humidity level in addition with a well controlled air flow at each mask surface, preventing masks from haze degradation and particle contamination, turns out to be a notable technical achievement. The longterm stability of haze critical masks has been improved significantly. Relevant environmental parameters like

    Single-domain antibodies libraries of heavy-chain only immunoglobulins from camelids or shark are enriched for high-affinity antigen-specific binders by a short in vivo immunization. Thus, potent binders are readily retrieved from relatively small-sized libraries of 10 7 -10 8 individual transformants, mostly after phage display and panning on a purified target. However, the remaining drawback of this strategy arises from the need to generate a dedicated library, for nearly every envisaged target. Therefore, all the procedures that shorten and facilitate the construction of an immune library of best possible quality are definitely a step forward. In this chapter, we provide the protocol to generate a high-quality immune VHH library using the Golden Gate Cloning strategy employing an adapted phage display vector where a lethal ccdB gene has to be substituted by the VHH gene. With this procedure, the construction of the library can be shortened to less than a week starting from bleeding the animal. Our libraries exceed 10 8 individual transformants and close to 100% of the clones harbor a phage display vector having an insert with the length of a VHH gene. These libraries are also more economic to make than previous standard approaches using classical restriction enzymes and ligations. The quality of the Nanobodies that are retrieved from immune libraries obtained by Golden Gate Cloning is identical to those from immune libraries made according to the classical procedure.

    A high energy, high beam quality short-pulse diode-pumped Nd:YAG master oscillator power-amplifier (MOPA) laser with two amplifier stages is demonstrated. The two-rod birefringence compensation was used as beam quality controlling methods, which presents a short-pulse energy of 40 mJ with a beam quality value of M2 = 1.2 at a repetition rate of 400Hz. The MOPA system delivers a short-pulse energy of 712.5 mJ with a pulse width of 12.4 ns.The method of spherical aberration compensation is improved the beam quality, a M2 factor of 2.3 and an optical-to-optical efficiency of 27.7% is obtained at the maximum laser out power.The laser obtained 1.4J out energy with polarization integration.

  13. Development of nuclear quality high pressure valve bellows in Canada

    Janzen, P.; Astill, C.J.


    Concurrent with the decision to use bellows stem sealed nuclear valves where feasible in commercial-scale CANDU plants, AECL undertook to develop an indigenous high pressure valve bellows technology. This program included developing the capability to fabricate improved high pressure valve bellows in conjunction with a Canadian manufacturer. This paper describes the evolution of a two-stage bellows fabrication process involving: (1) manufacture of discrete lengths of precision thin wall telescoping tubes - from preparation of strip blanks through edge grinding and edge forming to longitudinal welding; (2) forming of bellows from tube assemblies using a novel combination of mechanical inward forming followed by hydraulic outward forming. Bellows of Inconel 600 and Inconel 625 have been manufactured and evaluated. Test results indicate comparable to improved performance over alternative high quality bellows. (author)

  14. Fat Quality Influences the Obesogenic Effect of High Fat Diets

    Raffaella Crescenzo


    Full Text Available High fat and/or carbohydrate intake are associated with an elevated risk for obesity and chronic diseases such as diabetes and cardiovascular diseases. The harmful effects of a high fat diet could be different, depending on dietary fat quality. In fact, high fat diets rich in unsaturated fatty acids are considered less deleterious for human health than those rich in saturated fat. In our previous studies, we have shown that rats fed a high fat diet developed obesity and exhibited a decrease in oxidative capacity and an increase in oxidative stress in liver mitochondria. To investigate whether polyunsaturated fats could attenuate the above deleterious effects of high fat diets, energy balance and body composition were assessed after two weeks in rats fed isocaloric amounts of a high-fat diet (58.2% by energy rich either in lard or safflower/linseed oil. Hepatic functionality, plasma parameters, and oxidative status were also measured. The results show that feeding on safflower/linseed oil diet attenuates the obesogenic effect of high fat diets and ameliorates the blood lipid profile. Conversely, hepatic steatosis and mitochondrial oxidative stress appear to be negatively affected by a diet rich in unsaturated fatty acids.

    Wiggins, S M; Issac, R C; Welsh, G H; Brunetti, E; Shanks, R P; Anania, M P; Cipiccia, S; Manahan, G G; Aniculaesei, C; Ersfeld, B; Islam, M R; Burgess, R T L; Vieux, G; Jaroszynski, D A [SUPA, Department of Physics, University of Strathclyde, Glasgow (United Kingdom); Gillespie, W A [SUPA, Division of Electronic Engineering and Physics, University of Dundee, Dundee (United Kingdom); MacLeod, A M [School of Computing and Creative Technologies, University of Abertay Dundee, Dundee (United Kingdom); Van der Geer, S B; De Loos, M J, E-mail: [Pulsar Physics, Burghstraat 47, 5614 BC Eindhoven (Netherlands)


    High quality electron beams have been produced in a laser-plasma accelerator driven by femtosecond laser pulses with a peak power of 26 TW. Electrons are produced with an energy up to 150 MeV from the 2 mm gas jet accelerator and the measured rms relative energy spread is less than 1%. Shot-to-shot stability in the central energy is 3%. Pepper-pot measurements have shown that the normalized transverse emittance is {approx}1{pi} mm mrad while the beam charge is in the range 2-10 pC. The generation of high quality electron beams is understood from simulations accounting for beam loading of the wakefield accelerating structure. Experiments and self-consistent simulations indicate that the beam peak current is several kiloamperes. Efficient transportation of the beam through an undulator is simulated and progress is being made towards the realization of a compact, high peak brilliance free-electron laser operating in the vacuum ultraviolet and soft x-ray wavelength ranges.

    Saadati, Fatemeh; Sehhatiei Shafaei, Fahimeh; Mirghafourvand, Mozhgan


    Sleep is one of the most basic human requirements. This research aims at determining the status of sleep quality and its relationship with quality of life among high-risk pregnant women in Tabriz, Iran, in 2015. This research was a sectional study done on 364 qualified women in 28-36 weeks of pregnancy suffering from mild preeclampsia and gestational diabetes. The sampling was done as convenience. Personal-social-midwifery questionnaire, Pittsburg sleep quality, and quality of life in pregnancy (QOL-ORAV) were used for gathering data. Multivariate linear regression model was used for determining the relationship between sleep quality and its subsets with quality of life and controlling confounders. In the current study, the prevalence of sleep disturbance was 96.4%. Mean (SD) of the total score of sleep quality was 10.1 (4.1) and the total score of quality of life was 61.7 (17.3). According to Pearson's correlation test, there was statistically significant relationship between quality of life and sleep quality and all its subsets except sleep duration and use of sleep medication (p quality of life. The findings of current research show that sleep quality is low among high-risk pregnant women and quality of life is medium. So, it is necessary that required training is given by health cares for improving sleep quality and quality of life to mothers.

  20. Anti-Stokes Luminescence in High Quality Quantum Wells

    Vinattieri, A.; Bogani, F.; Miotto, A.; Ceccherini, S.


    We present a detailed investigation of the anti-Stokes (AS) luminescence which originates from exciton recombination when below gap excitation is used, in a set of high quality quantum well structures. We observe strong excitonic resonances in the AS signal as measured from photoluminescence and photoluminescence excitation spectra. We demonstrate that neither the electromagnetic coupling between the wells nor the morphological disorder can explain this up-conversion effect. Time-resolved luminescence data after ps excitation and fs correlation spectroscopy results provide clear evidence of the occurrence of a two-step absorption which is assisted by the exciton population resonantly excited by the first photon.

  1. The quality of high-energy X-ray beams

    LaRiviere, P.D.


    Supplement 17 of the British Journal of Radiology is a survey of central-axis depth doses for radiotherapy machines, patterned largely on BJR Supplement 11 (1972). Inspection of high-energy X-ray depth doses for a 10 x 10 cm field at an SSD of 100 cm disclosed large differences between the two sets of data, especially for qualities above 8 MV, e.g. a depth dose of 80% at 10 cm is rated at about 19 MV according to BJR Supplement 11, and 23 MV according to BJR Supplement 17. It was found that Supplement 17 depth-dose data above 8 MV were erratic, but Supplement 11 data could be represented by an analytical expression, providing a unique means of assigning MV quality. It was also found that dose-weighted average energy of the filtered beam plotted smoothly against depth dose. For dosimetric purposes, it is suggested that this parameter be used as a true measure of beam quality, removing discrepancies introduced by the use of nominal MV for this purpose. (author)

  2. CCD Astrophotography High-Quality Imaging from the Suburbs

    Stuart, Adam


    This is a reference book for amateur astronomers who have become interested in CCD imaging. Those glorious astronomical images found in astronomy magazines might seem out of reach to newcomers to CCD imaging, but this is not the case. Great pictures are attainable with modest equipment. Adam Stuart’s many beautiful images, reproduced in this book, attest to the quality of – initially – a beginner’s efforts. Chilled-chip astronomical CCD-cameras and software are also wonderful tools for cutting through seemingly impenetrable light-pollution. CCD Astrophotography from the Suburbs describes one man’s successful approach to the problem of getting high-quality astronomical images under some of the most light-polluted conditions. Here is a complete and thoroughly tested program that will help every CCD-beginner to work towards digital imaging of the highest quality. It is equally useful to astronomers who have perfect observing conditions, as to those who have to observe from light-polluted city skies.

    We evaluated the reliability of a rotational angiographic unit (RA) with flat-panel detector as a single technique to guide percutaneous vertebroplasty (PVP) and for post-procedure assessment by 2D and 3D reformatted images. Fifty-five consecutive patients (104 vertebral bodies) were treated under RA fluoroscopy. Rotational acquisitions with 2D and 3D reconstruction were obtained in all patients for immediate post-procedure assessment. In complex cases, this technique was also used to evaluate the needle position during the procedure. All patients underwent CT scan after the procedure. RA and CT findings were compared. In all cases, a safe trans-pedicular access and an accurate control of the bone-cement injection were successfully performed with high-quality fluoroscopy, even at the thoracic levels and in case of vertebra plana. 2D and 3D rotational reconstructions permitted CT-like images that clearly showed needle position and were similar to CT findings in depicting intrasomatic implant-distribution. RA detected 40 cement leakages compared to 42 demonstrated by CT and showed overall 95% sensitivity and 100% specificity compared to CT for final post-procedure assessment. Our preliminary results suggest that high-quality RA is reliable and safe as a single technique for PVP guidance, control and post-procedure assessment. It permits fast and cost-effective procedures avoiding multi-modality imaging.

  5. Computer-aided control of high-quality cast iron

    S. Pietrowski


    Full Text Available The study discusses the possibility of control of the high-quality grey cast iron and ductile iron using the author’s genuine computer programs. The programs have been developed with the help of algorithms based on statistical relationships that are said to exist between the characteristic parameters of DTA curves and properties, like Rp0,2, Rm, A5 and HB. It has been proved that the spheroidisation and inoculation treatment of cast iron changes in an important way the characteristic parameters of DTA curves, thus enabling a control of these operations as regards their correctness and effectiveness, along with the related changes in microstructure and mechanical properties of cast iron. Moreover, some examples of statistical relationships existing between the typical properties of ductile iron and its control process were given for cases of the melts consistent and inconsistent with the adopted technology.A test stand for control of the high-quality cast iron and respective melts has been schematically depicted.

  6. Automated high speed volume computed tomography for inline quality control

    Hanke, R.; Kugel, A.; Troup, P.


    Increasing complexity of innovative products as well as growing requirements on quality and reliability call for more detailed knowledge about internal structures of manufactured components rather by 100 % inspection than just by sampling test. A first-step solution, like radioscopic inline inspection machines, equipped with automated data evaluation software, have become state of the art in the production floor during the last years. However, these machines provide just ordinary two-dimensional information and deliver no volume data e.g. to evaluate exact position or shape of detected defects. One way to solve this problem is the application of X-ray computed tomography (CT). Compared to the performance of the first generation medical scanners (scanning times of many hours), today, modern Volume CT machines for industrial applications need about 5 minutes for a full object scan depending on the object size. Of course, this is still too long to introduce this powerful method into the inline production quality control. In order to gain acceptance, the scanning time including subsequent data evaluation must be decreased significantly and adapted to the manufacturing cycle times. This presentation demonstrates the new technical set up, reconstruction results and the methods for high-speed volume data evaluation of a new fully automated high-speed CT scanner with cycle times below one minute for an object size of less than 15 cm. This will directly create new opportunities in design and construction of more complex objects. (author)

  7. Production of high quality water for oil sands application

    Beaudette-Hodsman, C.; Macleod, B. [Pall Corp., Mississauga, ON (Canada); Venkatadri, R. [Pall Corp., East Hills, NY (United States)


    This paper described a pressurized microfiltration membrane system installed at an oil sands extraction site in Alberta. The system was designed to complement a reverse osmosis (RO) system installed at the site to produce the high quality feed water required by the system's boilers. Groundwater in the region exhibited moderate total suspended solids and high alkalinity and hardness levels, and the RO system required feed water with a silt density index of 3 or less. The conventional pretreatment system used at the site was slowing down production due to the severe fouling of the RO membranes. The new microfiltration system contained an automated PVDF hollow fiber microfiltration membrane system contained in a trailer. Suspended particles and bacteria were captured within the filter, and permeate was sent to the RO unit. Within 6 hours of being installed, the unit was producing water with SDI values in the range of 1.0 to 2.5. It was concluded that the microfiltration system performed reliably regardless of wide variations in feed water quality and flow rates. 3 refs., 1 tab., 8 figs.

  8. High Framingham risk score decreases quality of life in adults

    Christian Yosaputra


    Full Text Available Cardiovascular disease (CVD risk factors, such as diabetes, hypertension, hypercholesterolemia, smoking, and obesity tend to occur together in the general population. Increasing prevalence of multiple CVD risk factors has been related to increased risk of death from coronary heart disease and stroke. Studies have suggested that people with several risk factors of CVD may have impaired health-related quality of life. The objective of this study was to assess the association of CVD risk factors with quality of life (QOL among adults aged 40 to 65 years. A cross-sectional study was conducted involving 220 subjects 40 - 65 years of age at a health center. The CVD risk factors were assessed using the Framingham risk score that is the standard instrument for assessment of the risk of a first cardiac event. The risk factors assessed were age, smoking, blood pressure, total cholesterol and high density lipoprotein cholesterol concentrations. QOL was assessed by means of the WHOQOL-BREF instrument that had been prevalidated. The results of the study showed that 28.2% of subjects were smokers, 56.4% had stage 1 hypertension, 42.8% high total cholesterol and 13.6% low HDL cholesterol. The high risk group amounted to 45.5% and 42.3% constitued an intermediate risk group. High CVD risk scores were significantly associated with a low QOL for all domains (physical, psychological, social and environment (p=0.000. Preventing or reducing the multiple CVD risk factors to improve QOL is necessary among adults.

  12. Automated Theorem Proving in High-Quality Software Design

    Schumann, Johann; Swanson, Keith (Technical Monitor)


    The amount and complexity of software developed during the last few years has increased tremendously. In particular, programs are being used more and more in embedded systems (from car-brakes to plant-control). Many of these applications are safety-relevant, i.e. a malfunction of hardware or software can cause severe damage or loss. Tremendous risks are typically present in the area of aviation, (nuclear) power plants or (chemical) plant control. Here, even small problems can lead to thousands of casualties and huge financial losses. Large financial risks also exist when computer systems are used in the area of telecommunication (telephone, electronic commerce) or space exploration. Computer applications in this area are not only subject to safety considerations, but also security issues are important. All these systems must be designed and developed to guarantee high quality with respect to safety and security. Even in an industrial setting which is (or at least should be) aware of the high requirements in Software Engineering, many incidents occur. For example, the Warshaw Airbus crash, was caused by an incomplete requirements specification. Uncontrolled reuse of an Ariane 4 software module was the reason for the Ariane 5 disaster. Some recent incidents in the telecommunication area, like illegal "cloning" of smart-cards of D2GSM handies, or the extraction of (secret) passwords from German T-online users show that also in this area serious flaws can happen. Due to the inherent complexity of computer systems, most authors claim that only a rigorous application of formal methods in all stages of the software life cycle can ensure high quality of the software and lead to real safe and secure systems. In this paper, we will have a look, in how far automated theorem proving can contribute to a more widespread application of formal methods and their tools, and what automated theorem provers (ATPs) must provide in order to be useful.

  13. Recruiting and retaining high-quality teachers in rural areas.

    Monk, David H


    In examining recruitment and retention of teachers in rural areas, David Monk begins by noting the numerous possible characteristics of rural communities--small size, sparse settlement, distance from population concentrations, and an economic reliance on agricultural industries that are increasingly using seasonal and immigrant workers to minimize labor costs. Many, though not all, rural areas, he says, are seriously impoverished. Classes in rural schools are relatively small, and teachers tend to report satisfaction with their work environments and relatively few problems with discipline. But teacher turnover is often high, and hiring can be difficult. Monk observes that rural schools have a below-average share of highly trained teachers. Compensation in rural schools tends to be low, perhaps because of a lower fiscal capacity in rural areas, thus complicating efforts to attract and retain teachers. Several student characteristics, including relatively large shares of students with special needs and with limited English skills and lower shares of students attending college, can also make it difficult to recruit and retain high-quality teachers. Other challenges include meeting the needs of highly mobile children of low-income migrant farm workers. With respect to public policy, Monk asserts a need to focus on a subcategory of what might be called hard-to-staff rural schools rather than to develop a blanket set of policies for all rural schools. In particular, he recommends a focus on such indicators as low teacher qualifications, teaching in fields far removed from the area of training, difficulty in hiring, high turnover, a lack of diversity among teachers in the school, and the presence of migrant farm workers' children. Successful efforts to stimulate economic growth in these areas would be highly beneficial. He also calls attention to the potential for modern telecommunication and computing technologies to offset some of the drawbacks associated with teaching

    Guzman Calcina, Carmen S.; Almeida, Adelaide de; Rocha, Jose R. Oliveira


    A Quality Assurance program should be installed also for High Dose Rate brachytherapy, in the order to achieve a correct dose administration to the patient and for the safety to those involved directly with the treatment. The work presented here has the following purposes: Analyze the types of equipment tests presented by the official protocols (TG40, TG56 e ARCAL XXX), evaluate the brachytherapy routine tests of protocols from various national and international radiotherapy services and compare the latter with those presented in the official protocols. As a result, we conclude the following: TG56 presents a higher number of tests when compared to the other official protocols and most of the tests presented by the analyzed services are present in TG56. A suggestion for a basic protocol is presented, emphasizing the periodicity and tolerance level of each of the tests. (author)

  15. High quality diesel fuels by VO-LSGO hydrotreatment

    Stanica-Ezeanu, Dorin; Juganaru, Traian [Petroleum and Gas Univ. of Ploiesti (Romania)


    The aim of the paper is to obtain a high quality Diesel fuel by hydro-deoxigenation of vegetable oils (VO) mixed with a low sulfur gasoil (LSGO). The process is possible by using a bi-functional catalyst Ni-Mo supported by an activated Al{sub 2}O{sub 3} containing 2% Ultrastable Y-zeolite. The experimental conditions were: T =340 - 380 C, Pressure = 50 bar, LHSV = 1,5 h{sup -1}, H{sub 2}/Feed ratio = 15 mole H{sub 2} /mole liquid feed. The liquid product was separated in two fractions: a light distillate (similar to gasoline) and a heavy distillate (boiling point > 200 C) with very good characteristics for Diesel engines. The reaction chemistry is very complex, but the de-oxygenation process is decisive for the chemical structure of hydrocarbons from final product. Finally, a schema for the reaction mechanism is proposed. (orig.)

  16. Supercapacitors based on high-quality graphene scrolls

    Zeng, Fanyan; Kuang, Yafei; Liu, Gaoqin; Liu, Rui; Huang, Zhongyuan; Fu, Chaopeng; Zhou, Haihui


    High-quality graphene scrolls (GSS) with a unique scrolled topography are designed using a microexplosion method. Their capacitance properties are investigated by cyclic voltammetry, galvanostatic charge-discharge and electrical impedance spectroscopy. Compared with the specific capacity of 110 F g-1 for graphene sheets, a remarkable capacity of 162.2 F g-1 is obtained at the current density of 1.0 A g-1 in 6 M KOH aqueous solution owing to the unique scrolled structure of GSS. The capacity value is increased by about 50% only because of the topological change of graphene sheets. Meanwhile, GSS exhibit excellent long-term cycling stability along with 96.8% retained after 1000 cycles at 1.0 A g-1. These encouraging results indicate that GSS based on the topological structure of graphene sheets are a kind of promising material for supercapacitors.

    Graphene was discovered half a decade ago and proved the existence of a two-dimensional system which becomes stable as a result of 3D corrugation. It appeared very quickly that this exceptional material had truly outstanding electronic, mechanical, thermal and optical properties. Consequently a broad range of applications appeared, as the graphene science speedily moved forward. Since then, a lot of effort has been devoted not only to the study of graphene but also to its fabrication. Here we review the chemical approaches to graphene production, their advantages as well as their downsides.

    Stornaiuolo, D; Longobardi, L; Massarotti, D; Barone, A; Tafuri, F [CNR-SPIN Napoli, Complesso Universitario di Monte Sant' Angelo, via Cinthia, 80126 Napoli (Italy); Papari, G; Carillo, F [NEST, CNR-NANO and Scuola Normale Superiore, Piazza San Silvestro 12, 56127 Pisa (Italy); Cennamo, N [Dipartimento Ingegneria dell' Informazione, Seconda Universita degli Studi di Napoli, via Roma 29, 81031 Aversa (Italy)


    We have extended the off-axis biepitaxial technique to produce YBCO grain boundary junctions on low loss substrates. Excellent transport properties have been reproducibly found, with remarkable values of the quality factor I{sub c}R{sub n} (with I{sub c} the critical current and R{sub n} the normal state resistance) above 10 mV, far higher than the values commonly reported in the literature for high temperature superconductor (HTS) based Josephson junctions. The outcomes are consistent with a picture of a more uniform grain boundary region along the current path. This work supports a possible implementation of grain boundary junctions for various applications including terahertz sensors and HTS quantum circuits in the presence of microwaves.

  19. A roadmap to high quality chemically prepared graphene

    Gengler, Regis Y N; Spyrou, Konstantinos; Rudolf, Petra


    Graphene was discovered half a decade ago and proved the existence of a two-dimensional system which becomes stable as a result of 3D corrugation. It appeared very quickly that this exceptional material had truly outstanding electronic, mechanical, thermal and optical properties. Consequently a broad range of applications appeared, as the graphene science speedily moved forward. Since then, a lot of effort has been devoted not only to the study of graphene but also to its fabrication. Here we review the chemical approaches to graphene production, their advantages as well as their downsides. Our aim is to draw a roadmap of today's most reliable path to high quality graphene via chemical preparation.

    Full Text Available We undertook a detailed ethnographic study of the dance creation process of a noted choreographer and his distinguished troupe. All choreographer dancer interactions were videoed, the choreographer and dancers were interviewed extensively each day, as well as other observations and tests performed. The choreographer used three main methods to produce high quality and novel content: showing, making-on, and tasking. We present, analyze and evaluate these methods, and show how these approaches allow the choreographer to increase the creative output of the dancers and him. His methods, although designed for dance, apply more generally to other creative endeavors, especially where brainstorming is involved, and where the creative process is distributed over many individuals. His approach is also a case study in multi-modal direction, owing to the range of mechanisms he uses to communicate and direct.

  1. Biotransformation of Organic Waste into High Quality Fertilizer

    Bryndum, Sofie

    Agriculture faces several challenges of future provision of nutrients such as limited P reserves and increasing prices of synthetic fertilizers and recycling of nutrients from organic waste can be an important strategy for the long-term sustainability of the agricultural systems. Organically...... and S, is often low; and (3) the unbalanced composition of nutrients rarely matches crop demands. Therefore the objective of this project was to investigate the potential for (1) recycling nutrients from agro-industrial wastes and (2) compost biotransformation into high-quality organic fertilizers...... other uses into fertilizer use would be unlikely. An estimated ~50 % of the total organic waste pool, primarily consisting of animal manure and waste from the processing of sugar cane, coffee, oil palm and oranges, is currently being re-used as “fertilizers”, meaning it is eventually returned...

  5. Biology Reflective Assessment Curriculum

    Bayley, Cheryl Ann

    Often students and educators view assessments as an obligation and finality for a unit. In the current climate of high-stakes testing and accountability, the balance of time, resources and emphasis on students' scores related to assessment have been slanted considerably toward the summative side. This tension between assessment for accountability and assessment to inform teaching strains instruction and educators' ability to use that information to design learning opportunities that help students develop deeper conceptual understanding. A substantive body of research indicates that formative and reflective assessment can significantly improve student learning. Biology Reflective Assessment Curriculum (BRAC) examines support provided for high school science students through assessment practices. This investigation incorporates the usage of reflective assessments as a guiding practice for differentiated instruction and student choice. Reflective assessment is a metacognitive strategy that promotes self-monitoring and evaluation. The goals of the curriculum are to promote self-efficacy and conceptual understanding in students learning biology through developing their metacognitive awareness. BRAC was implemented in a high school biology classroom. Data from assessments, metacognitive surveys, self-efficacy surveys, reflective journals, student work, a culminating task and field notes were used to evaluate the effectiveness of the curriculum. The results suggest that students who develop their metacognitive skills developed a deeper conceptual understanding and improved feelings of self-efficacy when they were engaged in a reflective assessment unit embedded with student choice. BRAC is a tool for teachers to use assessments to assist students in becoming metacognitive and to guide student choice in learning opportunities.

  6. Medical humanities in the undergraduate medical curriculum.

    Supe, Avinash


    The medical humanities have been introduced in medical curricula over the past 30 years in the western world. Having medical humanities in a medical school curriculum can nurture positive attitudes in the regular work of a clinician and contribute equally to personality development. Though substantial evidence in favour of a medical humanities curriculum may be lacking, the feedback is positive. It is recommended that medical humanities be introduced into the curriculum of every medical school with the purpose of improving the quality of healthcare, and the attitudes of medical graduates.

  7. A 13-week research-based biochemistry laboratory curriculum.

    Lefurgy, Scott T; Mundorff, Emily C


    Here, we present a 13-week research-based biochemistry laboratory curriculum designed to provide the students with the experience of engaging in original research while introducing foundational biochemistry laboratory techniques. The laboratory experience has been developed around the directed evolution of an enzyme chosen by the instructor, with mutations designed by the students. Ideal enzymes for this curriculum are able to be structurally modeled, solubly expressed, and monitored for activity by UV/Vis spectroscopy, and an example curriculum for haloalkane dehalogenase is given. Unique to this curriculum is a successful implementation of saturation mutagenesis and high-throughput screening of enzyme function, along with bioinformatics analysis, homology modeling, structural analysis, protein expression and purification, polyacrylamide gel electrophoresis, UV/Vis spectroscopy, and enzyme kinetics. Each of these techniques is carried out using a novel student-designed mutant library or enzyme variant unique to the lab team and, importantly, not described previously in the literature. Use of a well-established set of protocols promotes student data quality. Publication may result from the original student-generated hypotheses and data, either from the class as a whole or individual students that continue their independent projects upon course completion. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(5):437-448, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

  9. High quality protein microarray using in situ protein purification

    Fleischmann Robert D


    Full Text Available Abstract Background In the postgenomic era, high throughput protein expression and protein microarray technologies have progressed markedly permitting screening of therapeutic reagents and discovery of novel protein functions. Hexa-histidine is one of the most commonly used fusion tags for protein expression due to its small size and convenient purification via immobilized metal ion affinity chromatography (IMAC. This purification process has been adapted to the protein microarray format, but the quality of in situ His-tagged protein purification on slides has not been systematically evaluated. We established methods to determine the level of purification of such proteins on metal chelate-modified slide surfaces. Optimized in situ purification of His-tagged recombinant proteins has the potential to become the new gold standard for cost-effective generation of high-quality and high-density protein microarrays. Results Two slide surfaces were examined, chelated Cu2+ slides suspended on a polyethylene glycol (PEG coating and chelated Ni2+ slides immobilized on a support without PEG coating. Using PEG-coated chelated Cu2+ slides, consistently higher purities of recombinant proteins were measured. An optimized wash buffer (PBST composed of 10 mM phosphate buffer, 2.7 mM KCl, 140 mM NaCl and 0.05% Tween 20, pH 7.4, further improved protein purity levels. Using Escherichia coli cell lysates expressing 90 recombinant Streptococcus pneumoniae proteins, 73 proteins were successfully immobilized, and 66 proteins were in situ purified with greater than 90% purity. We identified several antigens among the in situ-purified proteins via assays with anti-S. pneumoniae rabbit antibodies and a human patient antiserum, as a demonstration project of large scale microarray-based immunoproteomics profiling. The methodology is compatible with higher throughput formats of in vivo protein expression, eliminates the need for resin-based purification and circumvents

  10. The structure of high-quality aluminium cast iron

    D. Kopyciński


    Full Text Available In this study presents the analyse of aluminium iron cast structure (as-cast condition which are used in high temperature. While producing the casts of aluminium iron major influence has been preserve the structure of technological process parameters. The addition to Fe-C-Al alloy V, Ti, Cr leads to the improvement of functional and mechanical cast qualities. In this study, a method was investigated to eliminate the presence of undesirable Al4C3 phases in a aluminium cast iron structure and thus improve the production process. V and Ti additions in aluminium cast iron allows to development of FeAl - VC or TiC alloys. In particular, V or Ti contents above 5 wt.% were found to totally eliminate the presence of Al4C3. In addition, preliminary work indicates that the alloy with the FeAl - VC or TiC structure reveals high oxidation resistance. The introduction of 5 wt.% chromium to aluminium cast iron strengthened Al4C3 precipitate. Thus, the resultant alloy can be considered an intermetallic FeAl matrix strengthened by VC and TiC or modified Al4C3 reinforcements.

  11. High-Quality Seismic Observations of Sonic Booms

    Wurman, Gilead; Haering, Edward A., Jr.; Price, Michael J.


    The SonicBREWS project (Sonic Boom Resistant Earthquake Warning Systems) is a collaborative effort between Seismic Warning Systems, Inc. and NASA Dryden Flight Research Center. This project aims to evaluate the effects of sonic booms on Earthquake Warning Systems in order to prevent such systems from experiencing false alarms due to sonic booms. The airspace above the Antelope Valley, California includes the High Altitude Supersonic Corridor and the Black Mountain Supersonic Corridor. These corridors are among the few places in the US where supersonic flight is permitted, and sonic booms are commonplace in the Antelope Valley. One result of this project is a rich dataset of high-quality accelerometer records of sonic booms which can shed light on the interaction between these atmospheric phenomena and the solid earth. Nearly 100 sonic booms were recorded with low-noise triaxial MEMS accelerometers recording 1000 samples per second. The sonic booms had peak overpressures ranging up to approximately 10 psf and were recorded in three flight series in 2010 and 2011. Each boom was recorded with up to four accelerometers in various array configurations up to 100 meter baseline lengths, both in the built environment and the free field. All sonic booms were also recorded by nearby microphones. We present the results of the project in terms of the potential for sonic-boom-induced false alarms in Earthquake Warning Systems, and highlight some of the interesting features of the dataset.

  12. High-quality remote interactive imaging in the operating theatre

    Grimstead, Ian J.; Avis, Nick J.; Evans, Peter L.; Bocca, Alan


    We present a high-quality display system that enables the remote access within an operating theatre of high-end medical imaging and surgical planning software. Currently, surgeons often use printouts from such software for reference during surgery; our system enables surgeons to access and review patient data in a sterile environment, viewing real-time renderings of MRI & CT data as required. Once calibrated, our system displays shades of grey in Operating Room lighting conditions (removing any gamma correction artefacts). Our system does not require any expensive display hardware, is unobtrusive to the remote workstation and works with any application without requiring additional software licenses. To extend the native 256 levels of grey supported by a standard LCD monitor, we have used the concept of "PseudoGrey" where slightly off-white shades of grey are used to extend the intensity range from 256 to 1,785 shades of grey. Remote access is facilitated by a customized version of UltraVNC, which corrects remote shades of grey for display in the Operating Room. The system is successfully deployed at Morriston Hospital, Swansea, UK, and is in daily use during Maxillofacial surgery. More formal user trials and quantitative assessments are being planned for the future.

    Childbirth Connection hosted a 90th Anniversary national policy symposium, Transforming Maternity Care: A High Value Proposition, on April 3, 2009, in Washington, DC. Over 100 leaders from across the range of stakeholder perspectives were actively engaged in the symposium work to improve the quality and value of U.S. maternity care through broad system improvement. A multi-disciplinary symposium steering committee guided the strategy from its inception and contributed to every phase of the project. The "Blueprint for Action: Steps Toward a High Quality, High Value Maternity Care System", issued by the Transforming Maternity Care Symposium Steering Committee, answers the fundamental question, "Who needs to do what, to, for, and with whom to improve the quality of maternity care over the next five years?" Five stakeholder workgroups collaborated to propose actionable strategies in 11 critical focus areas for moving expeditiously toward the realization of the long term "2020 Vision for a High Quality, High Value Maternity Care System", also published in this issue. Following the symposium these workgroup reports and recommendations were synthesized into the current blueprint. For each critical focus area, the "Blueprint for Action" presents a brief problem statement, a set of system goals for improvement in that area, and major recommendations with proposed action steps to achieve them. This process created a clear sightline to action that if enacted could improve the structure, process, experiences of care, and outcomes of the maternity care system in ways that when anchored in the culture can indeed transform maternity care.

  16. High-quality endoscope reprocessing decreases endoscope contamination.

    Decristoforo, P; Kaltseis, J; Fritz, A; Edlinger, M; Posch, W; Wilflingseder, D; Lass-Flörl, C; Orth-Höller, D


    Several outbreaks of severe infections due to contamination of gastrointestinal (GI) endoscopes, mainly duodenoscopes, have been described. The rate of microbial endoscope contamination varies dramatically in literature. The aim of this multicentre prospective study was to evaluate the hygiene quality of endoscopes and automated endoscope reprocessors (AERs) in Tyrol/Austria. In 2015 and 2016, a total of 463 GI endoscopes and 105 AERs from 29 endoscopy centres were analysed by a routine (R) and a combined routine and advanced (CRA) sampling procedure and investigated for microbial contamination by culture-based and molecular-based analyses. The contamination rate of GI endoscopes was 1.3%-4.6% according to the national guideline, suggesting that 1.3-4.6 patients out of 100 could have had contacts with hygiene-relevant microorganisms through an endoscopic intervention. Comparison of R and CRA sampling showed 1.8% of R versus 4.6% of CRA failing the acceptance criteria in phase I and 1.3% of R versus 3.0% of CRA samples failing in phase II. The most commonly identified indicator organism was Pseudomonas spp., mainly Pseudomonas oleovorans. None of the tested viruses were detected in 40 samples. While AERs in phase I failed (n = 9, 17.6%) mainly due to technical faults, phase II revealed lapses (n = 6, 11.5%) only on account of microbial contamination of the last rinsing water, mainly with Pseudomonas spp. In the present study the contamination rate of endoscopes was low compared with results from other European countries, possibly due to the high quality of endoscope reprocessing, drying and storage.

  18. Sociology of Hidden Curriculum

    Alireza Moradi


    Full Text Available This paper reviews the concept of hidden curriculum in the sociological theories and wants to explain sociological aspects of formation of hidden curriculum. The main question concentrates on the theoretical approaches in which hidden curriculum is explained sociologically.For this purpose it was applied qualitative research methodology. The relevant data include various sociological concepts and theories of hidden curriculum collected by the documentary method. The study showed a set of rules, procedures, relationships and social structure of education have decisive role in the formation of hidden curriculum. A hidden curriculum reinforces by existed inequalities among learners (based on their social classes or statues. There is, in fact, a balance between the learner's "knowledge receptions" with their "inequality proportion".The hidden curriculum studies from different major sociological theories such as Functionalism, Marxism and critical theory, Symbolic internationalism and Feminism. According to the functionalist perspective a hidden curriculum has a social function because it transmits social values. Marxists and critical thinkers correlate between hidden curriculum and the totality of social structure. They depicts that curriculum prepares learners for the exploitation in the work markets. Symbolic internationalism rejects absolute hegemony of hidden curriculum on education and looks to the socialization as a result of interaction between learner and instructor. Feminism theory also considers hidden curriculum as a vehicle which legitimates gender stereotypes.

  20. Design of accounting curriculum: The case of Estonia

    Alver Lehte


    Full Text Available The process of globalization sets new requirements for the professional qualification of accountants and auditors. In the business world globalized investment market demands consistent high quality financial information across borders; investors are looking for a global accounting profession to provide it. There is more pressure on accounting professionals to expand and enhance their knowledge, skills, and abilities beyond what they are currently likely to possess. Providers of accounting education must take into account the changed world and create contemporary curricula. In Estonia the change from a command to a market economy has inevitably influenced not only the accounting framework but also the entire system of accounting education. It is clear that without a design of accounting curricula it is practically impossible to fulfill requirements of nowadays high quality financial information. Tallinn University of Technology (TUT holds on the advanced level of accounting education the leading position in Estonia. The accounting curriculum (on the graduate level as well as undergraduate level is the most popular among all curricula at the Tallinn School of Economics and Business Administration of TUT. It is a joint system, which consists of undergraduate and graduate degree programs. Small sub specializations: for example in financial accounting, managerial cost accounting, taxation and auditing become evident while interpreting the graduate and undergraduate programs as one united system. The paper explains a new model of accounting curriculum developed at TUT as well as its educational philosophy and principles of designing. It also describes conditions required for development and continuous improvement of competitive curriculum.

  2. Development of a Comprehensive Communication Skills Curriculum for Pediatrics Residents.

    Peterson, Eleanor B; Boland, Kimberly A; Bryant, Kristina A; McKinley, Tara F; Porter, Melissa B; Potter, Katherine E; Calhoun, Aaron W


    Effective communication is an essential element of medical care and a priority of medical education. Specific interventions to teach communication skills are at the discretion of individual residency programs. We developed the Resident Communication Skills Curriculum (RCSC), a formal curriculum designed to teach trainees the communication skills essential for high-quality practice. A multidisciplinary working group contributed to the development of the RCSC, guided by an institutional needs assessment, literature review, and the Accreditation Council for Graduate Medical Education core competencies. The result was a cohesive curriculum that incorporates didactic, role play, and real-life experiences over the course of the entire training period. Methods to assess curricular outcomes included self-reporting, surveys, and periodic faculty evaluations of the residents. Curricular components have been highly rated by residents (3.95-3.97 based on a 4-point Likert scale), and residents' self-reported communication skills demonstrated an improvement over the course of residency in the domains of requesting a consultation, providing effective handoffs, handling conflict, and having difficult conversations (intern median 3.0, graduate median 4.0 based on a 5-point Likert scale, P  ≤ .002). Faculty evaluations of residents have also demonstrated improvement over time (intern median 3.0, graduate median 4.5 based on a 5-point Likert scale, P  communication skills curriculum for pediatrics residents was implemented, with a multistep evaluative process showing improvement in skills over the course of the residency program. Positive resident evaluations and informal comments from faculty support its general acceptance. The use of existing resources makes this curriculum feasible.

  4. Low-quality birds do not display high-quality signals: The cysteine-pheomelanin mechanism of honesty

    Galván, Ismael; Wakamatsu, Kazumasa; Camarero, Pablo R; Mateo, Rafael; Alonso-Alvarez, Carlos


    The mechanisms that make that the costs of producing high-quality signals are unaffordable to low-quality signalers are a current issue in animal communication. The size of the melanin-based bib of male house sparrows Passer domesticus honestly signals quality. We induced the development of new bibs while treating males with buthionine-sulfoximine (BSO), a substance that depletes the levels of the antioxidant glutathione (GSH) and the amino acid cysteine, two elements that switch melanogenesis from eumelanin to pheomelanin. Final bib size is negatively related to pheomelanin levels in the bib feathers. BSO reduced cysteine and GSH levels in all birds, but improved phenotypes (bibs larger than controls) were only expressed by high-quality birds (BSO birds with largest bibs initially). Negative associations between final bib size and cysteine levels in erythrocytes, and between pheomelanin and cysteine levels, were observed in high-quality birds only. These findings suggest that a mechanism uncoupling pheomelanin and cysteine levels may have evolved in low-quality birds to avoid producing bibs of size not corresponding to their quality and greater relative costs. Indeed, greater oxidative stress in cells was not observed in low-quality birds. This may represent the first mechanism maintaining signal honesty without producing greater relative costs on low-quality signalers. PMID:25330349

  5. Systems and processes that ensure high quality care.

    Bassett, Sally; Westmore, Kathryn


    This is the second in a series of articles examining the components of good corporate governance. It considers how the structures and processes for quality governance can affect an organisation's ability to be assured about the quality of care. Complex information systems and procedures can lead to poor quality care, but sound structures and processes alone are insufficient to ensure good governance, and behavioural factors play a significant part in making sure that staff are enabled to provide good quality care. The next article in this series looks at how the information reporting of an organisation can affect its governance.

  6. Characterization of non equilibrium effects on high quality critical flows

    Camelo, E.; Lemonnier, H.; Ochterbeck, J.


    The appropriate design of various pieces of safety equipment such as relief systems, relies on the accurate description of critical flow phenomena. Most of the systems of industrial interest are willing to be described by one-dimensional area-averaged models and a large fraction of them involves multi-component high gas quality flows. Within these circumstances, the flow is very likely to be of an annular dispersed nature and its description by two-fluid models requires various closure relations. Among the most sensitive closures, there is the interfacial area and the liquid entrained fraction. The critical flowrate depends tremendously on the accurate description of the non equilibrium which results from the correctness of the closure equations. In this study, two-component flows are emphasized and non equilibrium results mainly form the differences in the phase velocities. It is therefore of the utmost importance to have reliable data to characterize non equilibrium phenomena and to assess the validity of the closure models. A comprehensive description of air-water nozzle flows, with emphasis on the effect of the nozzle geometry, has been undertaken and some of the results are presented here which helps understanding the overall flow dynamics. Besides the critical flowrate, the presented material includes pressure profiles, droplet size and velocity, liquid film flowrate and liquid film thickness

  8. Image Quality in High-resolution and High-cadence Solar Imaging

    Denker, C.; Dineva, E.; Balthasar, H.; Verma, M.; Kuckein, C.; Diercke, A.; González Manrique, S. J.


    Broad-band imaging and even imaging with a moderate bandpass (about 1 nm) provides a photon-rich environment, where frame selection (lucky imaging) becomes a helpful tool in image restoration, allowing us to perform a cost-benefit analysis on how to design observing sequences for imaging with high spatial resolution in combination with real-time correction provided by an adaptive optics (AO) system. This study presents high-cadence (160 Hz) G-band and blue continuum image sequences obtained with the High-resolution Fast Imager (HiFI) at the 1.5-meter GREGOR solar telescope, where the speckle-masking technique is used to restore images with nearly diffraction-limited resolution. The HiFI employs two synchronized large-format and high-cadence sCMOS detectors. The median filter gradient similarity (MFGS) image-quality metric is applied, among others, to AO-corrected image sequences of a pore and a small sunspot observed on 2017 June 4 and 5. A small region of interest, which was selected for fast-imaging performance, covered these contrast-rich features and their neighborhood, which were part of Active Region NOAA 12661. Modifications of the MFGS algorithm uncover the field- and structure-dependency of this image-quality metric. However, MFGS still remains a good choice for determining image quality without a priori knowledge, which is an important characteristic when classifying the huge number of high-resolution images contained in data archives. In addition, this investigation demonstrates that a fast cadence and millisecond exposure times are still insufficient to reach the coherence time of daytime seeing. Nonetheless, the analysis shows that data acquisition rates exceeding 50 Hz are required to capture a substantial fraction of the best seeing moments, significantly boosting the performance of post-facto image restoration.

  11. Paying for High- and Low-Quality Teaching

    Schacter, John; Thum, Yeow Meng


    The extensive research on teacher quality has led to two conclusions. First, there are large and significant differences among teachers in terms of their capacity to improve student achievement. Second, these differences are not captured by common measures of teacher qualifications (E.A. Hanushek, Teacher quality, in: L.T. Izumi, W.M. Evers…

  12. Teaching quality: High school students' autonomy and competence.

    León, Jaime; Medina-Garrido, Elena; Ortega, Miriam


    How teachers manage class learning and interact with students affects students’ motivation and engagement. However, it could be that the effect of students’ representation of teaching quality on the students’ motivation varies between classes. Students from 90 classes participated in the study. We used multilevel random structural equation modeling to analyze whether the relationship of the students’ perception of teaching quality (as an indicator of the students’ mental representation) and students’ motivation varies between classes, and if this variability depends on the class assessment of teaching quality (as an indicator of teaching quality). The effect of teachers’ structure on the regression slope of student perception of student competence was .127. The effect of teachers’ autonomy support on the regression slope of student perception of student autonomy was .066. With this study we contribute a more detailed description of the relationship between teaching quality, competence and autonomy.

  13. Crowdsourced Curriculum Development for Online Medical Education.

    Shappell, Eric; Chan, Teresa M; Thoma, Brent; Trueger, N Seth; Stuntz, Bob; Cooney, Robert; Ahn, James


    In recent years online educational content, efforts at quality appraisal, and integration of online material into institutional teaching initiatives have increased. However, medical education has yet to develop large-scale online learning centers. Crowd-sourced curriculum development may expedite the realization of this potential while providing opportunities for innovation and scholarship. This article describes the current landscape, best practices, and future directions for crowdsourced curriculum development using Kern's framework for curriculum development and the example topic of core content in emergency medicine. A scoping review of online educational content was performed by a panel of subject area experts for each step in Kern's framework. Best practices and recommendations for future development for each step were established by the same panel using a modified nominal group consensus process. The most prevalent curriculum design steps were (1) educational content and (2) needs assessments. Identified areas of potential innovation within these steps included targeting gaps in specific content areas and developing underrepresented instructional methods. Steps in curriculum development without significant representation included (1) articulation of goals and objectives and (2) tools for curricular evaluation. By leveraging the power of the community, crowd-sourced curriculum development offers a mechanism to diffuse the burden associated with creating comprehensive online learning centers. There is fertile ground for innovation and scholarship in each step along the continuum of curriculum development. Realization of this paradigm's full potential will require individual developers to strongly consider how their contributions will align with the work of others.

  14. New developments in high quality grey cast irons

    Iulian Riposan


    Full Text Available The paper reviews original data obtained by the present authors, revealed in recent separate publications, describing specific procedures for high quality grey irons, and reflecting the forecast needs of the worldwide iron foundry industry. High power, medium frequency coreless induction furnaces are commonly used in electric melting grey iron foundries. This has resulted in low sulphur (1,500 °C, contributing to unfavourable conditions for graphite nucleation. Thin wall castings are increasingly produced by these electric melt shops with a risk of greater eutectic undercooling during solidification. The paper focused on two groups of grey cast irons and their specific problems: carbides and graphite morphology control in lower carbon equivalent high strength irons (CE=3.4%-3.8%, and austenite dendrite promotion in eutectic and slightly hypereutectic irons (CE=4.1%-4.5%, in order to increase their strength characteristics. There are 3 stages and 3 steps involving graphite formation, iron chemistry and iron processing that appear to be important. The concept in the present paper sustains a threestage model for nucleating flake graphite [(Mn,XS type nuclei]. There are three important groups of elements (deoxidizer, Mn/S, and inoculant and three technological stages in electric melting of iron (superheat, pre-conditioning of base iron, final inoculation. Attention is drawn to a control factor (%Mn x (%S ensuring it equals to 0.03 – 0.06, accompanied by 0.005wt.%–0.010wt.% Al and/or Zr content in inoculated irons. It was found that iron powder addition promotes austenite dendrite formation in eutectic and slightly eutectic, acting as reinforcement for the eutectic cells. But, there is an accompanying possible negative influence on the characteristics of the (Mn,XS type graphite nuclei (change the morphology of nuclei from polygonal compact to irregular polygonal, and therefore promote chill tendency in treated irons.

  15. A high yielding, better quality chickpea mutant variety 'NIFA-95'

    Hassan, S.; Javed, M.A.; Khattak, S.U.K.; Iqbal, M.M.


    Chickpea or gram (Cicer arietinum L.) is an important legume crop of Pakistan, grown on over one million hectares annually. The national average yield of the crop is very low (0.5 t/ha) and thus the country had to spent about 2 billion rupees ($ 50 million) on import of pulses. The main causes of low yield are non-availability of genetic sources for resistance to various diseases especially gram blight Ascochyta rabiei (Pass.) Lab., insect pest (Pod borer) and non-adoption of proper production technology by the farmers. This calls for earnest efforts of breeders to evolve high yielding and disease resistant varieties of chickpea for provision of quality seeds to the farming community to increase production of this important crop. Seeds of a highly blight susceptible variety '6153' were irradiated at 200 Gy dose of gamma radiation in 1985 and the promising mutant line CMN-446-4 was selected in M3 generation on the basis of disease resistance, greater number of pods and better plant type. After confirmation of its resistance to blight in M 4 and M 5 , the mutant line was evaluated in various trials at different locations. In the advanced and zonal yield trials during 1993-95, the line CMN-446-4 produced the highest grain yield of 2,600 kg/ha as compared to the rest of the mutants and varieties. The line was also evaluated in the chickpea national uniform yield trial, conducted on over 11 locations in the country during 1993-94. In this trial, the mutant line ranked 3rd by producing an average yield of 1,528 kg/ha as compared to the two check varieties 'Punjab-91' (1,316 kg/ha) and 'Paidar-91' (1,391 kg/ha). The mutant line CMN-446-4 is moderately resistant to gram blight, highly resistant to stored pest (pulse beetle), contains 25.3% more protein as compared to the parental variety 6153 and is also better in nitrogen fixing capacity.The proposal for release of the mutant line CMN-446-4 as a new variety under the name 'NIFA-95' for general cultivation in the rainfed

  17. Physics and quality assurance for high dose rate brachytherapy

    Anderson, Lowell L.


    Purpose: To review the physical aspects of high dose rate (HDR) brachytherapy, including commissioning and quality assurance, source calibration and dose distribution measurements, and treatment planning methods. Following the introduction of afterloading in brachytherapy, development efforts to make it 'remote' culminated in 1964 with the near-simultaneous appearance of remote afterloaders in five major medical centers. Four of these machines were 'high dose rate', three employing 60Co and one (the GammaMed) using a single, cable-mounted 192Ir source. Stepping-motor source control was added to the GammaMed in 1974, making it the precursor of modern remote afterloaders, which are now suitable for interstitial as well as intracavitary brachytherapy by virtue of small source-diameter and indexer-accessed multiple channels. Because the 192Ir sources currently used in HDR remote afterloaders are supplied at a nominal air-kerma strength of 11.4 cGy cm2 s-1 (10 Ci), are not collimated in clinical use, and emit a significant fraction (15%) of photons at energies greater than 600 keV, shielding and facility design must be undertaken as carefully and thoroughly as for external beam installations. Licensing requirements of regulatory agencies must be met with respect both to maximum permissible dose limits and to the existence and functionality of safety devices (door interlocks, radiation monitors, etc.). Commissioning and quality assurance procedures that must be documented for HDR remote afterloading relate to (1) machine, applicator, guide-tube, and facility functionality checks, (2) source calibration, (3) emergency response readiness, (4) planning software evaluation, and (5) independent checks of clinical dose calculations. Source calibration checks must be performed locally, either by in-air measurement of air kerma strength or with a well ionization chamber calibrated (by an accredited standards laboratory) against an in-air measurement of air kerma strength for the

  18. Twin pregnancy possibly associated with high semen quality

    Asklund, Camilla; Jensen, Tina Kold; Jørgensen, Niels


    BACKGROUND: Recent studies found an association between a long waiting time to pregnancy (TTP) and reduced probability of twinning and a reduced dizygotic (DZ) twinning rate in subfertile men. However, it remains unsolved whether semen quality is associated with twin offspring. We therefore studied...... the semen quality in a group of fathers of naturally conceived twins. METHODS: In this study, 37 fathers of DZ twins and 15 fathers of monozygotic (MZ) twins participated, and 349 normal fertile men served as a reference group. All men delivered a semen sample, underwent a physical examination and completed...... points higher than the reference group (P semen quality than the reference group, which supports...

    Zhu Sheng; Xu Binshi; Yao JiuKun


    This paper introduced the structure of the high efficiency hypersonic plasma spraying gun and the effects of hypersonic plasma jet on the sprayed particles. The optimised spraying process parameters for several ceramic powders such as Al 2 O 3 , Cr 2 O 3 , ZrO 2 , Cr 3 C 2 and Co-WC were listed. The properties and microstructure of the sprayed ceramic coatings were investigated. Nano Al 2 O 3 -TiO 2 ceramic coating sprayed by using the high efficiency hypersonic plasma spraying was also studied. Compared with the conventional air plasma spraying, high efficiency hypersonic plasma spraying improves greatly the ceramic coatings quality but at low cost. (orig.)

  20. Nucleonics across the curriculum

    Marrano, Rich


    Many within the ''nuclear'' community are interested in attracting young people to careers in nuclear related fields while they are at the age when they are considering career choices. High school is a good to introduce students to ideas that may lead them to investigate careers in nuclear science. However, they may not even be exposed to those ideas for various reasons. For example, many teachers may not see the connection between nuclear issues and other areas of instruction. In addition, most teachers already have a full curriculum, and adding another topic is unlikely. As a result many students will not see some of the practical applications of nuclear science in other fields of study unless they take a class where nuclear science is a specified topic of study. A good alternative is to incorporate nuclear examples across the curriculum to illustrate concepts already included in other classes. This would be a simple step that teachers may find interesting and would expose a variety of students to nuclear issues. (author)

  2. High throughput electrospinning of high-quality nanofibers via an aluminum disk spinneret

    Zheng, Guokuo

    In this work, a simple and efficient needleless high throughput electrospinning process using an aluminum disk spinneret with 24 holes is described. Electrospun mats produced by this setup consisted of fine fibers (nano-sized) of the highest quality while the productivity (yield) was many times that obtained from conventional single-needle electrospinning. The goal was to produce scaled-up amounts of the same or better quality nanofibers under variable concentration, voltage, and the working distance than those produced with the single needle lab setting. The fiber mats produced were either polymer or ceramic (such as molybdenum trioxide nanofibers). Through experimentation the optimum process conditions were defined to be: 24 kilovolt, a distance to collector of 15cm. More diluted solutions resulted in smaller diameter fibers. Comparing the morphologies of the nanofibers of MoO3 produced by both the traditional and the high throughput set up it was found that they were very similar. Moreover, the nanofibers production rate is nearly 10 times than that of traditional needle electrospinning. Thus, the high throughput process has the potential to become an industrial nanomanufacturing process and the materials processed by it may be used as filtration devices, in tissue engineering, and as sensors.

  4. UWHS Climate Science: Uniting University Scientists and High School Teachers in the Development and Implementation of a Dual-Credit STEM-Focused Curriculum

    Bertram, M. A.; Thompson, L.; Ackerman, T. P.


    course used the UW Atmospheric Sciences curriculum, exams, and textbook (The Earth System, 3rd edition, Kump, Kasting and Crane, 2010), and one of the hands-on modules. Communication with these instructors during the year helped us define assessment strategies and to identify challenges of bringing the material into the high school classroom. This knowledge will be shared with teachers during our summer 2012 workshop and will inform approaches to teaching the course in 2012/2013. Proposed formats for implementation include year-long courses, using the APES/Climate format of 2011/2012, a union of Oceanography and Climate content, or in the context of an engineering course. Our initial vision was for a stand-alone semester or year-long course in climate science, incorporating excel and data handling as a learning tool and a suite of hands-on learning opportunities. Yet, the creative approaches to implementation of a new course in the schools, together with the breadth and depth of the UW curriculum and the Kump et al. 2010 textbook, have resulted in diverse educational approaches for bringing climate science into the high school.

  5. Investigating the Role of the Teacher in Science Curriculum: New Evidence for an Old Debate

    Penuel, W.; McAuliffe, C.; McWilliams, H.


    It is widely believed that teachers need high-quality curriculum materials to improve teaching and learning. Professional development designs differ, however, in whether they emphasize preparing teachers to use expert- designed curricula or preparing teachers with the tools needed to design and implement high-quality science units themselves. Evidence exists for the effectiveness of providing teachers with training in how to implement expert-designed curricula (Bredderman, 1983; Shymansky, Hedges, & Woodworth, 1990; Weinstein, Boulanger, & Walberg, 1982) and for providing teachers with professional development aimed at preparing teachers to design instruction and assessments (Black & Harrison, 2001; Shepard, 1997; Sneider, Adams, Ibanez, Templeton, & Porter, 1996). However, no studies, however, have compared explicitly these different approaches to preparing teachers to plan and enact instruction in science. The Transforming Instruction by Design in Earth Science (TIDES) project is an experimental study comparing the efficacy of three different approaches to professional development. The approaches differ with respect to the role that teachers are expected to play in curriculum. In one condition (Earth Science by Design), teachers learn how to design curriculum units in Earth science. In a second condition (Investigating Earth Systems), teachers learn how to adopt and implement curriculum materials developed by experts. In the third condition (Hybrid), teachers learn a principled approach to adapt expert-developed curriculum materials. The TIDES study is examining the impacts of each of the approaches to professional development on instructional planning and on the quality of assignments and assessments they give to students. We measured impacts on instructional planning using an end-of-unit questionnaire that focused on changes to teachers" overall approach to planning units of instruction, their strategies for organizing assignment, and materials they use in

  6. High Yield Chemical Vapor Deposition Growth of High Quality Large-Area AB Stacked Bilayer Graphene

    Liu, Lixin; Zhou, Hailong; Cheng, Rui; Yu, Woo Jong; Liu, Yuan; Chen, Yu; Shaw, Jonathan; Zhong, Xing; Huang, Yu; Duan, Xiangfeng


    Bernal stacked (AB stacked) bilayer graphene is of significant interest for functional electronic and photonic devices due to the feasibility to continuously tune its band gap with a vertical electrical field. Mechanical exfoliation can be used to produce AB stacked bilayer graphene flakes but typically with the sizes limited to a few micrometers. Chemical vapor deposition (CVD) has been recently explored for the synthesis of bilayer graphene but usually with limited coverage and a mixture of AB and randomly stacked structures. Herein we report a rational approach to produce large-area high quality AB stacked bilayer graphene. We show that the self-limiting effect of graphene growth on Cu foil can be broken by using a high H2/CH4 ratio in a low pressure CVD process to enable the continued growth of bilayer graphene. A high temperature and low pressure nucleation step is found to be critical for the formation of bilayer graphene nuclei with high AB stacking ratio. A rational design of a two-step CVD process is developed for the growth of bilayer graphene with high AB stacking ratio (up to 90 %) and high coverage (up to 99 %). The electrical transport studies demonstrated that devices made of the as-grown bilayer graphene exhibit typical characteristics of AB stacked bilayer graphene with the highest carrier mobility exceeding 4,000 cm2/V·s at room temperature, comparable to that of the exfoliated bilayer graphene.

  8. Consumers' expected quality and intention to purchase high quality pork meat.

    Papanagiotou, P; Tzimitra-Kalogianni, I; Melfou, K


    Expected quality is believed to be one of the most important factors that influence consumers' intention to purchase food. The present study seeks to explore the concept of pork meat expected quality and compare it with self-stated consumer intention to purchase pork meat. The aim is attempted by means of a field research conducted in Greece, following a conjoint analytic procedure. Results show that quality expectations comply with intention to buy pork, in many aspects. However, several differences have been identified. More specifically, country of origin and marbling appear to be more important for respondents' purchase decisions than they are for their quality evaluations, while the opposite appears to be true for price. Finally, socio-demographic factors such as gender, level of education, place of purchase and consumption habits seem to influence perceptions. Copyright © 2012 Elsevier Ltd. All rights reserved.

  16. Study and practice of flipped classroom in optoelectronic technology curriculum

    Shi, Jianhua; Lei, Bing; Liu, Wei; Yao, Tianfu; Jiang, Wenjie


    "Flipped Classroom" is one of the most popular teaching models, and has been applied in more and more curriculums. It is totally different from the traditional teaching model. In the "Flipped Classroom" model, the students should watch the teaching video afterschool, and in the classroom only the discussion is proceeded to improve the students' comprehension. In this presentation, "Flipped Classroom" was studied and practiced in opto-electronic technology curriculum; its effect was analyzed by comparing it with the traditional teaching model. Based on extensive and deep investigation, the phylogeny, the characters and the important processes of "Flipped Classroom" are studied. The differences between the "Flipped Classroom" and the traditional teaching model are demonstrated. Then "Flipped Classroom" was practiced in opto-electronic technology curriculum. In order to obtain high effectiveness, a lot of teaching resources were prepared, such as the high-quality teaching video, the animations and the virtual experiments, the questions that the students should finish before and discussed in the class, etc. At last, the teaching effect was evaluated through analyzing the result of the examination and the students' surveys.

  17. Attitudes among students and teachers on vertical integration between clinical medicine and basic science within a problem-based undergraduate medical curriculum.

    Brynhildsen, J; Dahle, L O; Behrbohm Fallsberg, M; Rundquist, I; Hammar, M


    Important elements in the curriculum at the Faculty of Health Sciences in Linköping are vertical integration, i.e. integration between the clinical and basic science sections of the curriculum, and horizontal integration between different subject areas. Integration throughout the whole curriculum is time-consuming for both teachers and students and hard work is required for planning, organization and execution. The aim was to assess the importance of vertical and horizontal integration in an undergraduate medical curriculum, according to opinions among students and teachers. In a questionnaire 102 faculty teachers and 106 students were asked about the importance of 14 different components of the undergraduate medical curriculum including vertical and horizontal integration. They were asked to assign between one and six points to each component (6 points = extremely important for the quality of the curriculum; 1 point = unimportant). Students as well as teachers appreciated highly both forms of integration. Students scored horizontal integration slightly but significantly higher than the teachers (median 6 vs 5 points; p=0.009, Mann-Whitney U-test), whereas teachers scored vertical integration higher than students (6 vs 5; p=0.019, Mann-Whitney U-test). Both students and teachers considered horizontal and vertical integration to be highly important components of the undergraduate medical programme. We believe both kinds of integration support problem-based learning and stimulate deep and lifelong learning and suggest that integration should always be considered deeply when a new curriculum is planned for undergraduate medical education.

  3. Manufacturing High-Quality Carbon Nanotubes at Lower Cost

    Benavides, Jeanette M.; Lidecker, Henning


    A modified electric-arc welding process has been developed for manufacturing high-quality batches of carbon nanotubes at relatively low cost. Unlike in some other processes for making carbon nanotubes, metal catalysts are not used and, consequently, it is not necessary to perform extensive cleaning and purification. Also, unlike some other processes, this process is carried out at atmospheric pressure under a hood instead of in a closed, pressurized chamber; as a result, the present process can be implemented more easily. Although the present welding-based process includes an electric arc, it differs from a prior electric-arc nanotube-production process. The welding equipment used in this process includes an AC/DC welding power source with an integral helium-gas delivery system and circulating water for cooling an assembly that holds one of the welding electrodes (in this case, the anode). The cathode is a hollow carbon (optionally, graphite) rod having an outside diameter of 2 in. (approximately equal to 5.1 cm) and an inside diameter of 5/8 in. (approximately equal to 1.6 cm). The cathode is partly immersed in a water bath, such that it protrudes about 2 in. (about 5.1 cm) above the surface of the water. The bottom end of the cathode is held underwater by a clamp, to which is connected the grounding cable of the welding power source. The anode is a carbon rod 1/8 in. (approximately equal to 0.3 cm) in diameter. The assembly that holds the anode includes a thumbknob- driven mechanism for controlling the height of the anode. A small hood is placed over the anode to direct a flow of helium downward from the anode to the cathode during the welding process. A bell-shaped exhaust hood collects the helium and other gases from the process. During the process, as the anode is consumed, the height of the anode is adjusted to maintain an anode-to-cathode gap of 1 mm. The arc-welding process is continued until the upper end of the anode has been lowered to a specified height

  6. Extended professional development for systemic curriculum reform

    Kubitskey, Mary Elizabeth

    Education standards call for adopting inquiry science instruction. Successful adoption requires professional development (PD) to support teachers, increasing the need for research on PD. This dissertation examines the question: What is the influence of high quality, curriculum aligned, long-term group workshops and related practice on teacher learning? I focus on the following subquestions: (1) What is the influence of high quality, curriculum aligned, long-term, group workshops on teacher knowledge and beliefs? (2) What is the impact of the workshops on teacher practice? (3) What is the influence of practice on student response? (4) What is the impact of practice and student response on teacher knowledge and beliefs? I focus on an instance of PD nested within a long-term systemic change initiative, tracing eleven science teachers' learning from workshops and associated enactments. The data included pre and post-unit interviews (n=22), two post-workshop interviews (n=17), workshop observations (n=2), classroom observations (n=24) and student work (n=351). I used mixed-methods analysis. Quantitative analysis measured teacher learning by comparing pre and post-unit interview ratings. Qualitative components included two case study approaches: logic model technique and cross-case synthesis, examining teacher learning within and across teachers. The findings suggested a teacher-learning model incorporating PD, teacher knowledge, beliefs, practice and student response. PD impacts teachers' knowledge by providing teachers with new knowledge, adapting previous knowledge, or convincing them to value existing knowledge they chose not to use. The workshops can influence beliefs, providing teachers with confidence and motivation to adopt the practice. Beliefs can mediate how knowledge manifested itself in practice that, in turn, impacts students' response. Student response influences the teachers' beliefs, either reinforcing or motivating change. This teacher-learning model

  8. The pathology informatics curriculum wiki: Harnessing the power of user-generated content.

    Kim, Ji Yeon; Gudewicz, Thomas M; Dighe, Anand S; Gilbertson, John R


    The need for informatics training as part of pathology training has never been so critical, but pathology informatics is a wide and complex field and very few programs currently have the resources to provide comprehensive educational pathology informatics experiences to their residents. In this article, we present the "pathology informatics curriculum wiki", an open, on-line wiki that indexes the pathology informatics content in a larger public wiki, Wikipedia, (and other online content) and organizes it into educational modules based on the 2003 standard curriculum approved by the Association for Pathology Informatics (API). In addition to implementing the curriculum wiki at, we have evaluated pathology informatics content in Wikipedia. Of the 199 non-duplicate terms in the API curriculum, 90% have at least one associated Wikipedia article. Furthermore, evaluation of articles on a five-point Likert scale showed high scores for comprehensiveness (4.05), quality (4.08), currency (4.18), and utility for the beginner (3.85) and advanced (3.93) learners. These results are compelling and support the thesis that Wikipedia articles can be used as the foundation for a basic curriculum in pathology informatics. The pathology informatics community now has the infrastructure needed to collaboratively and openly create, maintain and distribute the pathology informatics content worldwide (Wikipedia) and also the environment (the curriculum wiki) to draw upon its own resources to index and organize this content as a sustainable basic pathology informatics educational resource. The remaining challenges are numerous, but largest by far will be to convince the pathologists to take the time and effort required to build pathology informatics content in Wikipedia and to index and organize this content for education in the curriculum wiki.

  9. Numerical determination of injector design for high beam quality

    Boyd, J.K.


    The performance of a free electron laser strongly depends on the electron beam quality or brightness. The electron beam is transported into the free electron laser after it has been accelerated to the desired energy. Typically the maximum beam brightness produced by an accelerator is constrained by the beam brightness deliverd by the accelerator injector. Thus it is important to design the accelerator injector to yield the required electron beam brightness. The DPC (Darwin Particle Code) computer code has been written to numerically model accelerator injectors. DPC solves for the transport of a beam from emission through acceleration up to the full energy of the injector. The relativistic force equation is solved to determine particle orbits. Field equations are solved for self consistent electric and magnetic fields in the Darwin approximation. DPC has been used to investigate the beam quality consequences of A-K gap, accelerating stress, electrode configuration and axial magnetic field profile

  13. From Communication Skills to Skillful Communication: A Longitudinal Integrated Curriculum for Critical Care Medicine Fellows.

    Roze des Ordons, Amanda L; Doig, Christopher J; Couillard, Philippe; Lord, Jason


    Communication with patients and families in critical care medicine (CCM) can be complex and challenging. A longitudinal curricular model integrating multiple techniques within classroom and clinical milieus may facilitate skillful communication across diverse settings. In 2014-2015, the authors developed and implemented a curriculum for CCM fellows at the Cumming School of Medicine, University of Calgary, to promote the longitudinal development of skillful communication. A departmental needs assessment informed curriculum development. Five 4-hour classroom sessions were developed: basic communication principles, family meetings about goals and transitions of care, discussing patient safety incidents, addressing conflict, and offering organ donation. Teaching methods-including instructor-led presentations incorporating a consistent framework for approaching challenging conversations, simulation and clinical practice, and feedback from peers, trained facilitators, family members, and clinicians-supported integration of skills into the clinical setting and longitudinal development of skillful communication. Seven fellows participated during the first year of the curriculum. CCM fellows engaged enthusiastically in the program, commented that the framework provided was helpful, and highly valued the opportunity to practice challenging communication scenarios, learn from observing their peers, and receive immediate feedback. More detailed accounts of fellows', patients', and family members' experiences will be obtained to guide curricular development. The curriculum will be expanded to involve other members of the multidisciplinary intensive care unit team, and faculty education initiatives will be offered to enhance the quality of the feedback provided. The impact of the curriculum on initial skill development, retention, and progression will be assessed.

  3. Measurement system with high accuracy for laser beam quality.

    Ke, Yi; Zeng, Ciling; Xie, Peiyuan; Jiang, Qingshan; Liang, Ke; Yang, Zhenyu; Zhao, Ming


    Presently, most of the laser beam quality measurement system collimates the optical path manually with low efficiency and low repeatability. To solve these problems, this paper proposed a new collimated method to improve the reliability and accuracy of the measurement results. The system accuracy controlled the position of the mirror to change laser beam propagation direction, which can realize the beam perpendicularly incident to the photosurface of camera. The experiment results show that the proposed system has good repeatability and the measuring deviation of M2 factor is less than 0.6%.

  4. Rehosting of Bacterial Chaperones for High-Quality Protein Production▿

    Martínez-Alonso, Mónica; Toledo-Rubio, Verónica; Noad, Rob; Unzueta, Ugutz; Ferrer-Miralles, Neus; Roy, Polly; Villaverde, Antonio


    Coproduction of DnaK/DnaJ in Escherichia coli enhances solubility but promotes proteolytic degradation of their substrates, minimizing the yield of unstable polypeptides. Higher eukaryotes have orthologs of DnaK/DnaJ but lack the linked bacterial proteolytic system. By coexpression of DnaK and DnaJ in insect cells with inherently misfolding-prone recombinant proteins, we demonstrate simultaneous improvement of soluble protein yield and quality and proteolytic stability. Thus, undesired side effects of bacterial folding modulators can be avoided by appropriate rehosting in heterologous cell expression systems. PMID:19820142

  8. Publishing high-quality climate data on the semantic web

    Woolf, Andrew; Haller, Armin; Lefort, Laurent; Taylor, Kerry


    The effort over more than a decade to establish the semantic web [Berners-Lee et. al., 2001] has received a major boost in recent years through the Open Government movement. Governments around the world are seeking technical solutions to enable more open and transparent access to Public Sector Information (PSI) they hold. Existing technical protocols and data standards tend to be domain specific, and so limit the ability to publish and integrate data across domains (health, environment, statistics, education, etc.). The web provides a domain-neutral platform for information publishing, and has proven itself beyond expectations for publishing and linking human-readable electronic documents. Extending the web pattern to data (often called Web 3.0) offers enormous potential. The semantic web applies the basic web principles to data [Berners-Lee, 2006]: using URIs as identifiers (for data objects and real-world 'things', instead of documents) making the URIs actionable by providing useful information via HTTP using a common exchange standard (serialised RDF for data instead of HTML for documents) establishing typed links between information objects to enable linking and integration Leading examples of 'linked data' for publishing PSI may be found in both the UK ( and US ( The Bureau of Meteorology (BoM) is Australia's national meteorological agency, and has a new mandate to establish a national environmental information infrastructure (under the National Plan for Environmental Information, NPEI [BoM, 2012a]). While the initial approach is based on the existing best practice Spatial Data Infrastructure (SDI) architecture, linked-data is being explored as a technological alternative that shows great promise for the future. We report here the first trial of government linked-data in Australia under In this initial pilot study, we have taken BoM's new high-quality reference surface

  11. Bridges to Excellence--recognizing high-quality care: analysis of physician quality and resource use.

    Rosenthal, Meredith B; de Brantes, Francois S; Sinaiko, Anna D; Frankel, Matthew; Robbins, Russell D; Young, Sara


    To examine whether physicians who sought and received Bridges to Excellence (BTE) recognition performed better than similar physicians on a standardized set of population-based performance measures. Cross-sectional comparison of performance data. Using a claims dataset of all commercially insured members from 6 health plans in Massachusetts, we examined population-based measures of quality and resource use for physicians recognized by the BTE programs Physician Office Link and Diabetes Care Link, compared with nonrecognized physicians in the same specialties. Differences in performance were tested using generalized linear models. Physician Office Link-recognized physicians performed significantly better than their nonrecognized peers on measures of cervical cancer screening, mammography, and glycosylated hemoglobin testing. Diabetes Care Link-recognized physicians performed significantly better on all 4 diabetes process measures of quality, with the largest differences observed in microalbumin screening (17.7%). Patients of Physician Office Link-recognized physicians had a significantly greater percentage of their resource use accounted for by evaluation and management services (3.4%), and a smaller percentage accounted for by facility (-1.6%), inpatient ancillary (-0.1%), and nonmanagement outpatient services (-1.0%). After adjustment for patient age and sex, and case mix, Physician Office Link-recognized physicians had significantly fewer episodes per patient (0.13) and lower resource use per episode (dollars 130), but findings were mixed for Diabetes Care Link-recognized physicians. Our findings suggest that the BTE approach to ascertaining physician quality identifies physicians who perform better on claims-based quality measures and primary care physicians who use a less resource-intensive practice style.

  12. Technology as a Tool for Understanding: a Pipeline of Curriculum-based Programs for Grades 4 to high school

    Schuster, G.


    New NASA-funded educational initiatives make for a pipeline of products meeting the needs of today's educators in inner city schools, for NASA Explorer Schools and across the nation. Three projects include training and include: 1) WDLC [Weather Data Learning Center] , a math achievement program with data entry, inquiry-based investigations, and the application of math using weather maps and imagery for Grade 4; 2) Project 3D-VIEW, where students in Grades 5 and 6 become experts in air, life, water, land and Earth systems using 3D technologies requiring 3D glasses. A formal literacy and math piece are included, and 1200 teachers will be provided training and materials free beginning in Fall 2006, and 3) Signals of Spring, where students in Grades 7 to 8, or high school, use NASA data to explain the movement of dozens of birds, land and marine animals that are tracked by satellite. Comprehensive content in life and Earth science is taught with curricular activities, interactive mapping, image interpretation, and online journals and common misconceptions are dispelled. Scientist involvement and support for a project is essential for students who are developing process skills and performing science activities. Current research partners include Columbia University's Teachers College and Stanford University's School of Education.

  15. Introducing astronomy into high school physics curriculum through the use of the University of North Dakota Observatory

    Nolby, Caitlin Marie

    Astronomy education is currently lacking in the secondary level classroom. Many programs have been created to remedy this, including research opportunities for students and training workshops for educators. These reach only a small fraction of the population however, while remaining students still lack the opportunity to learn astronomy at the secondary level. This research addresses the creation of a program that will make astronomy education a recurring option for students across North Dakota through implementation of a two-week astronomy course at Grand Forks Central High School (GFCHS) in a class of 19 physics students. During ten class periods from April 16, 2012 through April 27, 2012, instruction included presentation of basic astronomy concepts and observational techniques as well as student participation in demonstrations and in-class activities. Original lesson plans also included a group research project on the astrometry of an asteroid. Students were given the option to visit the University of North Dakota (UND) Observatory the evening of April 20, 2012 for a public "star party" where they received a tour of the university's telescopes and research equipment. Students also took a field trip to the John D. Odegard School of Aerospace Sciences to tour Aviation and Space Studies facilities at UND on April 25, 2012. Students were given a pre-test at the start of the course, daily exit surveys at the end of each class period, and a post-test at the end of the two weeks. These assessments were used to evaluate student enjoyment, progress, and overall perception of the course. The research also identified common misconceptions in astronomy held by the learners and the most effective teaching methods. It was found that this course was overall successful in promoting the students' learning of astronomy. This analysis has been used to make improvements in future installments of the course and it is now available online to educators for use in the classroom.

  16. Academic coordination at university: Strategies for high quality education

    Maria del Mar Durán Bellonch


    Full Text Available Most lecturers and professors involved in teaching School Management and Education Management courses have been engaged in developing some innovative actions to improve the training quality that we offer to students in the Pedagogy degree at the Autonomous University of Barcelona. These actions are aimed at increasing co-ordination among the teaching staff when designing and implementing the course curricula. Co-ordination meetings, exchanges of teaching experiences, discussions about what, how and when to teach the different contents, in which courses and at what level, methodological issues pointed out through technical description cards or the elaboration of study cases to be solved have become the basis of relevant actions during the last academic years. This paper explains each one of them, and provides useful information about the theoretical background, the process carried out, some of the results obtained, the output and the tools created.

    Full Text Available The paper presents the influence of the type of furnace charging melting, refining and modification silumins 226 and 231 on the porosity and microstructure of castings. It was shown that in order to reduce or eliminate the porosity of the castings is necessary to the refining ECOSAL-AL113 of liquid silumin both in the melting furnace, and in the ladle and an additional nitrogen, in the heat furnace modified and refining with nitrogen. To control the effects of refining and modifying the TDA method was used. It was found that based on crystal- lization curve can be qualitatively assess the gas porosity of the castings. In order to control and quality control silumins author developed a computer program using the method of TDA, which sets out: Rm, A5, HB and casting porosity P and the concentration of hydrogen in them. The program also informs the technological procedures to be performed for liquid silumin improper preparation.

  18. A Model for Persistent Improvement of Medical Education as Illustrated by the Surgical Reform Curriculum HeiCuMed.

    Kadmon, Guni; Schmidt, Jan; De Cono, Nicola; Kadmon, Martina


    Heidelberg Medical School underwent a major curricular change with the implementation of the reform curriculum HeiCuMed (Heidelberg Curriculum Medicinale) in October 2001. It is based on rotational modules with daily cycles of interactive, case-based small-group seminars, PBL tutorials and training of sensomotor and communication skills. For surgical undergraduate training an organisational structure was developed that ensures continuity of medical teachers for student groups and enables their unimpaired engagement for defined periods of time while accounting for the daily clinical routine in a large surgery department of a university hospital. It includes obligatory didactic training, standardising teaching material on the basis of learning objectives and releasing teaching doctors from clinical duties for the duration of a module. To compare the effectiveness of the undergraduate surgical reform curriculum with that of the preceding traditional one as reflected by students' evaluations. The present work analyses student evaluations of the undergraduate surgical training between 1999 and 2008 including three cohorts (~360 students each) in the traditional curriculum and 13 cohorts (~150 students each) in the reform curriculum. The evaluation of the courses, their organisation, the teaching quality, and the subjective learning was significantly better in HeiCuMed than in the preceding traditional curriculum over the whole study period. A medical curriculum based on the implementation of interactive didactical methods is more important to successful teaching and the subjective gain of knowledge than knowledge transfer by traditional classroom teaching. The organisational strategy adopted in the surgical training of HeiCuMed has been successful in enabling the maintenance of a complex modern curriculum on a continuously high level within the framework of a busy surgical environment.

  2. Thematic curriculum approach

    Šefer Jasmina P.


    Full Text Available Thematic curriculum combines disciplines and media. The process is problem-oriented and the scenario most often follows the logic of exploring or storytelling. Those two approaches to teaching are appropriate because they fit into interdisciplinary and creative open-ended problem solving through play, as insisted upon by thematic curriculum. The matrix, where seven types of abilities intersect with five types of problems according to their degree of openness, defines well the outcomes of teaching. However, it did not prove to be suitable for planning the majority of activities in thematic curriculum, for it follows with difficulty the process of exploring or storytelling i.e. it disrupts the subject matter coherence of thematic curriculum. Therefore, it is suggested that matrix should be used for disciplinary curriculum planning but for that of thematic curriculum only in exclusive cases. The matrix should be used primarily as a framework for evaluating the distribution of various types of abilities and problem situations in teaching. The logic of diverse approaches to teaching reflects itself in the manner of planning and organizing the teaching process. Conceptual, visual-graphic, structural and other aids employed during educational process planning should suit the nature of the approach chosen. On the basis of qualitative investigations of educational process, in the present paper considerations are given to various approaches to teaching development of various drafts for the planning of teaching, and recognition of the logic of storytelling and exploring in thematic curriculum.

    Nygren, R.E.


    This paper interweaves some suggestions for developing actively cooled plasma-facing components (PFCs) for future fusion devices, with supporting examples taken from the design, fabrication and operation of Tore Supra's Phase III outboard pump limiter (OPL). This actively cooled midplane limiter, designed for heat and particle removal during long-pulse operation, has been operated under essentially thermally steady state conditions. Testing to identify braze flaws, analysis of the impact of joining flaws on the thermal-hydraulic performance of the OPL, and the extensive calorimetry and IR thermography used to confirm and update safe operating limits for power handling of the OPL are reviewed. This experience suggests that, for PFCs in future fusion devices, flaw-tolerant designs are possible; analyses of the impacts of flaws on performance can provide criteria for quality assurance; and validating appropriate methods of inspection for such flaws early in the design development of PFCs is prudent. The need for in-service monitoring is also discussed. (orig.)

  6. Health care in small prisons: incorporating high-quality standards.

    Rieder, Jean-Pierre; Casillas, Alejandra; Mary, Gérard; Secretan, Anne-Dominique; Gaspoz, Jean-Michel; Wolff, Hans


    In the past, health management in Geneva's six post-trial prisons had been variable and inconsistent. In 2008, the unit of penitentiary medicine of the Geneva University Hospitals was mandated to re-organize and provide health care at all six prison facilities. The specific aim of this paper is to outline the example as a practical solution to some of the common challenges in unifying the structure and process of health services across multiple small facilities, while meeting European prison health and local quality standards. Geneva's post-trial prisons are small and close to one another in geographical proximity - ideal conditions for the construction of a health mobile team (HMT). This multidisciplinary mobile team operated like a community ambulatory care model; it was progressively launched in all prison facilities in Geneva. The authors incorporated an implementation strategy where health providers partnered with prison and community stakeholders in the health delivery model's development and adaption process. The model's strategic initiatives are described along the following areas, in light of other international prison health activity and prior care models: access to a health care professional, equivalence of care, patient consent, confidentiality, humanitarian interventions, and professional competence and independence. From the perspective of the HMT members, the authors provide the "lessons learned" through this experience, especially to providers who are working on prison health services reform and coordination improvement. The paper particularly stresses the importance of partnering with community health stakeholders and prison staff, a key component to the approach.

  8. Bust economics: foragers choose high quality habitats in lean times

    Sonny S. Bleicher


    Full Text Available In environments where food resources are spatially variable and temporarily impoverished, consumers that encounter habitat patches with different food density should focus their foraging initially where food density is highest before they move to patches where food density is lower. Increasing missed opportunity costs should drive individuals progressively to patches with lower food density as resources in the initially high food density patches deplete. To test these expectations, we assessed the foraging decisions of two species of dasyurid marsupials (dunnarts: Sminthopsis hirtipes and S. youngsoni during a deep drought, or bust period, in the Simpson Desert of central Australia. Dunnarts were allowed access to three patches containing different food densities using an interview chamber experiment. Both species exhibited clear preference for the high density over the lower food density patches as measured in total harvested resources. Similarly, when measuring the proportion of resources harvested within the patches, we observed a marginal preference for patches with initially high densities. Models analyzing behavioral choices at the population level found no differences in behavior between the two species, but models analyzing choices at the individual level uncovered some variation. We conclude that dunnarts can distinguish between habitat patches with different densities of food and preferentially exploit the most valuable. As our observations were made during bust conditions, experiments should be repeated during boom times to assess the foraging economics of dunnarts when environmental resources are high.

  9. Whole high-quality light environment for humans and plants

    Sharakshane, Anton


    Plants sharing a single light environment on a spaceship with a human being and bearing a decorative function should look as natural and attractive as possible. And consequently they can be illuminated only with white light with a high color rendering index. Can lighting optimized for a human eye be effective and appropriate for plants? Spectrum-based effects have been compared under artificial lighting of plants by high-pressure sodium lamps and general-purpose white LEDs. It has been shown that for the survey sample phytochrome photo-equilibria does not depend significantly on the parameters of white LED light, while the share of phytoactive blue light grows significantly as the color temperature increases. It has been revealed that yield photon flux is proportional to luminous efficacy and increases as the color temperature decreases, general color rendering index Ra and the special color rendering index R14 (green leaf) increase. General-purpose white LED lamps with a color temperature of 2700 K, Ra > 90 and luminous efficacy of 100 lm/W are as efficient as the best high-pressure sodium lamps, and at a higher luminous efficacy their yield photon flux per joule is even bigger in proportion. Here we show that demand for high color rendering white LED light is not contradictory to the agro-technical objectives.

  12. Achieving high-quality care: a view from NICE.

    Leng, Gillian; Partridge, Gemma


    The National Institute for Health and Care Excellence (NICE) was established in 1999 to provide evidence-based guidance. The task of producing guidance by reviewing primary research data and using an advisory committee to develop evidence-based recommendations, is not straightforward. Guidance production is, however, less challenging than the task of putting evidence-based recommendations into practice.NICE is very sensitive to this challenge as, since 1999, over 1500 pieces of NICE guidance have been published. A number of pieces of guidance relate to heart disease, including pharmaceutical agents, new medical technologies and clinical guidelines. Examples include guidelines on acute heart failure and atrial fibrillation, and advice on technologies including edoxaban and implantable cardioverter defibrillators.The research evidence is clear that a change in practice rarely comes about as a result of simply disseminating guidance on best practice. Simple dissemination is particularly ineffective if the guidance has not been produced by a well-respected, credible organisation. It is also clear from the literature that implementation is more successful when more than one approach is taken, and when there is alignment between efforts at organisational, local and national levels.At an organisational level, there should be support from the Board for quality improvement, with ongoing measurement of progress. Resources should be provided for targeted change programmes, particularly where new guidance suggests improvements are required. A systematic process for putting change in place should include identifying barriers to change, agreeing interventions to overcome the barriers and drive forward improvement and planning for implementation and evaluation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Bruckel, Jeffrey; Carballo, Victoria; Kalibatas, Orinta; Soule, Michael; Wynne, Kathryn E; Ryan, Megan P; Shaw, Tim; Co, John Patrick T


    Quality, patient safety and value are important topics for graduate medical education (GME). Spaced education delivers case-based content in a structured longitudinal experience. Use of spaced education to deliver quality and safety education in GME at an institutional level has not been previously evaluated. To implement a spaced education course in quality, safety and value; to assess learner satisfaction; and to describe trainee knowledge in these areas. We developed a case-based spaced education course addressing learning objectives related to quality, safety and value. This course was offered to residents and fellows about two-thirds into the academic year (March 2014) and new trainees during orientation (June 2014). We assessed learner satisfaction by reviewing the course completion rate and a postcourse survey, and trainee knowledge by the per cent of correct responses. The course was offered to 1950 trainees. A total of 305 (15.6%) enrolled in the course; 265/305 (86.9%) answered at least one question, and 106/305 (34.8%) completed the course. Fewer participants completed the March programme compared with the orientation programme (42/177 (23.7%) vs 64/128 (50.0%), peducation can help deliver and assess learners' understanding of quality, safety and value principles. Offering a voluntary course may result in low completion. Learners were satisfied with their experience and were introduced to new concepts. Published by the BMJ Publishing Group Limited.

Use of nano-crystalline diamond further increases the frequency comp...

  17. Solar Fireworks - Integrating an Exhibit on Solar Physics and Space Science into the Science and Astronomy Curriculum of High-School and College Students

    Denker, C.; Wang, H.; Conod, K. D.; Wintemberg, T.; Calderon, I.


    Astronomers at The Newark Museum's Alice and Leonard Dreyfuss Planetarium teamed up with the New Jersey Institute of Technology's (NJIT) Center for Solar-Terrestrial Research (CSTR) and the Big Bear Solar Observatory in presenting Solar Fireworks. The exhibit opened on May 15, 2004 and features two exhibition kiosks with interactive touch screen displays, where students and other visitors can take "virtual tours" in the fields of solar physics, solar activity, Sun-Earth connection, and geo-sciences. Planetarium and museum visits are an integral part of the introductory physics and astronomy classes at NJIT and the exhibition has been integrated in the astronomy curriculum. For example, NJIT students of the Astronomy Club and regular astronomy courses were closely involved in the design and development of the exhibit. The exhibit is the latest addition to the long-running natural science exhibit "Dynamic Earth: Revealing Nature's Secrets" at the museum. More than 30,000 people per year attend various programs offered by the planetarium including public shows, more than a dozen programs for school groups, after school activities, portable planetarium outreach, outdoor sky watches, solar observing and other family events. More than 1,000 high school students visited the planetarium in 2004. The exhibit is accompanied by a yearly teacher workshop (the first one was held on October 18-20, 2004) to enhance the learning experience of classes visiting the Newark Museum. The planetarium and museum staff has been working with teachers of Newark high schools and has presented many workshops for educators on a wide range of topics from astronomy to zoology. At the conclusion of the exhibit in December 2005, the exhibit will go "on the road" and will be made available to schools or other museums. Finally, the exhibit will find its permanent home at the new office complex of CSTR at NJIT. Acknowledgements: Solar Fireworks was organized by The Newark Museum and the New Jersey

  20. Gap analysis: a method to assess core competency development in the curriculum.

    Fater, Kerry H


    To determine the extent to which safety and quality improvement core competency development occurs in an undergraduate nursing program. Rapid change and increased complexity of health care environments demands that health care professionals are adequately prepared to provide high quality, safe care. A gap analysis compared the present state of competency development to a desirable (ideal) state. The core competencies, Nurse of the Future Nursing Core Competencies, reflect the ideal state and represent minimal expectations for entry into practice from pre-licensure programs. Findings from the gap analysis suggest significant strengths in numerous competency domains, deficiencies in two competency domains, and areas of redundancy in the curriculum. Gap analysis provides valuable data to direct curriculum revision. Opportunities for competency development were identified, and strategies were created jointly with the practice partner, thereby enhancing relevant knowledge, attitudes, and skills nurses need for clinical practice currently and in the future.

    Potvin, Marie-Christine; Snider, Laurie; Prelock, Patricia A; Wood-Dauphinee, Sharon; Kehayia, Eva


    The health-related quality of life of school-aged children with high-functioning autism is poorly understood. The objectives of this study were to compare the health-related quality of life of children with high-functioning autism to that of typically developing peers and to compare child-self and parent-proxy reports of health-related quality of life of children. A cross-sectional study of children with high-functioning autism (n = 30) and peers (n = 31) was conducted using the Pediatric Quality of Life Inventory 4.0 Generic Core Scales. Children with high-functioning autism had significantly poorer health-related quality of life than peers whether reported by themselves (p children and parental scores suggested variance in points of view. This study specifically investigated health-related quality of life in children with high-functioning autism as compared to a sample of peers, from the child's perspective. It strengthens earlier findings that children with high-functioning autism experience poorer health-related quality of life than those without this disorder and points to the importance of clinicians working with families to identify areas in a child's life that promote or hinder their sense of well-being. © The Author(s) 2013.

  4. Dual-Readout Calorimetry for High-Quality Energy

    During the past seven years, the DREAM collaboration has systematically investigated all factors that determine and limit the precision with which the properties of hadrons and jets can be measured in calorimeters. Using simultaneous detection of the deposited energy and the Cerenkov light produced in hadronic shower development ${(dual}$ ${readout}$), the fluctuations in the electromagnetic shower fraction could be measured event by event their effects on signal linearity, response function and energy resolution eliminated. Detailed measurement of the time structure of the signals made it possible to measure the contirbutions of nuclear evaporation neutrons to the signals and thus reduce the effects of fluctuations in "invisible energy". We are now embarking on the construction of a full-scale calorimeter which incorporates all these elements and which should make it possible to measure the four-vectors of both electrons, hadrons and jets with very high precision, in an instrument that can be simply calibrat...

  5. Export is necessary to maintain high quality supply

    Sirugue, S.


    Nuclear industry achieves about 20% of its turnover with the export of equipment and services but nuclear trade is submitted to specific constrains like non-proliferation policies. According to IAEA the world capacity of nuclear power is expected to double allowing the development of emerging countries while reducing CO_2 emissions. The French commercial offer focuses on the high-end market with the EPR reactor and an intermediate power range reactor ATMEA-1 designed with MHI (Mitsubishi Heavy Industries). AREVA is the unique world operator able to master the entire chain of spent fuel reprocessing thanks to the La Hague plant. In the framework of the rebuilding of the French nuclear industry, discussions are ongoing to achieve partnerships with foreign partners in exchange of shares in AREVA and AREVA NP. Today's main challenges of AREVA are to reduce EPR cost, to speed EPR construction and to benefit fully of the move into the digital age. (A.C.)

    Pisut, D.; Powell, A. M.; Loomis, T.; Goel, V.; Mills, B.; Cowan, D.


    NOAA curates a vast treasure trove of environmental data, but one that is sometimes not easily accessed, especially for education, outreach, and media purposes. Traditional data portals in NOAA require extensive knowledge of the specific names of observation platforms, models, and analyses, along with nomenclature for variable outputs. A new website and web mapping service (WMS) from NOAA attempts to remedy such issues. The NOAA View data imagery portal provides a seamless entry point into data from across the agency: satellite, models, in-situ analysis, etc. The system provides the user with ability to browse, animate, and download high resolution (e.g., 4,000 x 2,000 pixel) imagery, Google Earth, and even proxy data files. The WMS architecture also allows the resources to be ingested into other software systems or applications.

  8. Recycle food wastes into high quality fish feeds for safe and quality fish production.

    Wong, Ming-Hung; Mo, Wing-Yin; Choi, Wai-Ming; Cheng, Zhang; Man, Yu-Bon


    The amount of food waste generated from modern societies is increasing, which has imposed a tremendous pressure on its treatment and disposal. Food waste should be treated as a valuable resource rather than waste, and turning it into fish feeds would be a viable alternative. This paper attempts to review the feasibility of using food waste to formulate feed pellets to culture a few freshwater fish species, such as grass carp, grey mullet, and tilapia, under polyculture mode (growing different species in the same pond). These species occupy different ecological niches, with different feeding modes (i.e., herbivorous, filter feeding, etc.), and therefore all the nutrients derived from the food waste could be efficiently recycled within the ecosystem. The problems facing environmental pollution and fish contamination; the past and present situation of inland fish culture (focusing on South China); upgrade of food waste based feed pellets by adding enzymes, vitamin-mineral premix, probiotics (yeast), prebiotics, and Chinese medicinal herbs into feeds; and potential health risks of fish cultivated by food waste based pellets are discussed, citing some local examples. It can be concluded that appropriate portions of different types of food waste could satisfy basic nutritional requirements of lower trophic level fish species such as grass carp and tilapia. Upgrading the fish pellets by adding different supplements mentioned above could further elevated the quality of feeds, leading to higher growth rates, and enhanced immunity of fish. Health risk assessments based on the major environmental contaminants (mercury, PAHs and DDTs) in fish flesh showed that fish fed food waste based pellets are safer for consumption, when compared with those fed commercial feed pellets.

  9. High-quality thorium TRISO fuel performance in HTGRs

    Verfondern, Karl [Forschungszentrum Juelich GmbH (Germany); Allelein, Hans-Josef [Forschungszentrum Juelich GmbH (Germany); Technische Hochschule Aachen (Germany); Nabielek, Heinz; Kania, Michael J.


    Thorium as a nuclear fuel has received renewed interest, because of its widespread availability and the good irradiation performance of Th and mixed (Th,U) oxide compounds as fuels in nuclear power systems. Early HTGR development employed thorium together with high-enriched uranium (HEU). After 1980, HTGR fuel systems switched to low-enriched uranium (LEU). After completing fuel development for the AVR and the THTR with BISO coated particles, the German program expanded its efforts utilizing thorium and HEU TRISO coated particles in advanced HTGR concepts for process heat applications (PNP) and direct-cycle electricity production (HHT). The combination of a low-temperature isotropic (LTI) inner and outer pyrocarbon layers surrounding a strong, stable SiC layer greatly improved manufacturing conditions and the subsequent contamination and defective particle fractions in production fuel elements. In addition, this combination provided improved mechanical strength and a higher degree of solid fission product retention, not known previously with high-temperature isotropic (HTI) BISO coatings. The improved performance of the HEU (Th, U)O{sub 2} TRISO fuel system was successfully demonstrated in three primary areas of development: manufacturing, irradiation testing under normal operating conditions, and accident simulation testing. In terms of demonstrating performance for advanced HTGR applications, the experimental failure statistic from manufacture and irradiation testing are significantly below the coated particle requirements specified for PNP and HHT designs at the time. Covering a range to 1300 C in normal operations and 1600 C in accidents, with burnups to 13% FIMA and fast fluences to 8 x 10{sup 25} n/m{sup 2} (E> 16 fJ), the performance results exceed the design limits on manufacturing and operational requirements for the German HTR-Modul concept, which are 6.5 x 10{sup -5} for manufacturing, 2 x 10{sup -4} for normal operating conditions, and 5 x 10{sup -4

  13. Timing of high-quality child care and cognitive, language, and preacademic development.

    Li, Weilin; Farkas, George; Duncan, Greg J; Burchinal, Margaret R; Vandell, Deborah Lowe


    The effects of high- versus low-quality child care during 2 developmental periods (infant-toddlerhood and preschool) were examined using data from the National Institute of Child Health and Human Development Study of Early Child Care. Propensity score matching was used to account for differences in families who used different combinations of child care quality during the 2 developmental periods. Findings indicated that cognitive, language, and preacademic skills prior to school entry were highest among children who experienced high-quality care in both the infant-toddler and preschool periods, somewhat lower among children who experienced high-quality child care during only 1 of these periods, and lowest among children who experienced low-quality care during both periods. Irrespective of the care received during infancy-toddlerhood, high-quality preschool care was related to better language and preacademic outcomes at the end of the preschool period; high-quality infant-toddler care, irrespective of preschool care, was related to better memory skills at the end of the preschool period.

  14. An approach to high speed ship ride quality simulation

    Malone, W. L.; Vickery, J. M.


    The high speeds attained by certain advanced surface ships result in a spectrum of motion which is higher in frequency than that of conventional ships. This fact along with the inclusion of advanced ride control features in the design of these ships resulted in an increased awareness of the need for ride criteria. Such criteria can be developed using data from actual ship operations in varied sea states or from clinical laboratory experiments. A third approach is to simulate ship conditions using measured or calculated ship motion data. Recent simulations have used data derived from a math model of Surface Effect Ship (SES) motion. The model in turn is based on equations of motion which have been refined with data from scale models and SES of up to 101 600-kg (100-ton) displacement. Employment of broad band motion emphasizes the use of the simulators as a design tool to evaluate a given ship configuration in several operational situations and also serves to provide data as to the overall effect of a given motion on crew performance and physiological status.

  16. Ten Tips for Engaging the Millennial Learner and Moving an Emergency Medicine Residency Curriculum into the 21st Century.

    Toohey, Shannon L; Wray, Alisa; Wiechmann, Warren; Lin, Michelle; Boysen-Osborn, Megan


    Millennial learners are changing the face of residency education because they place emphasis on technology with new styles and means of learning. While research on the most effective way to teach the millennial learner is lacking, programs should consider incorporating educational theories and multimedia design principles to update the curriculum for these new learners. The purpose of the study is to discuss strategies for updating an emergency medicine (EM) residency program's curriculum to accommodate the modern learner. These 10 tips provide detailed examples and approaches to incorporate technology and learning theories into an EM curriculum to potentially enhance learning and engagement by residents.

  17. Ten Tips for Engaging the Millennial Learner and Moving an Emergency Medicine Residency Curriculum into the 21st Century

    Shannon L. Toohey


    Full Text Available Introduction: Millennial learners are changing the face of residency education because they place emphasis on technology with new styles and means of learning. While research on the most effective way to teach the millennial learner is lacking, programs should consider incorporating educational theories and multimedia design principles to update the curriculum for these new learners. The purpose of the study is to discuss strategies for updating an emergency medicine (EM residency program’s curriculum to accommodate the modern learner. Discussion: These 10 tips provide detailed examples and approaches to incorporate technology and learning theories into an EM curriculum to potentially enhance learning and engagement by residents. Conclusion: While it is unclear whether technologies actually promote or enhance learning, millennials use these technologies. Identifying best practice, grounded by theory and active learning principles, may help learners receive quality, high-yield education. Future studies will need to evaluate the efficacy of these techniques to fully delineate best practices.

  18. Identifying suitable substrates for high-quality graphene-based heterostructures

    Banszerus, L.; Janssen, H.; Otto, M.; Epping, A.; Taniguchi, T.; Watanabe, K.; Beschoten, B.; Neumaier, D.; Stampfer, C.


    We report on a scanning confocal Raman spectroscopy study investigating the strain-uniformity and the overall strain and doping of high-quality chemical vapour deposited (CVD) graphene-based heterostuctures on a large number of different substrate materials, including hexagonal boron nitride (hBN), transition metal dichalcogenides, silicon, different oxides and nitrides, as well as polymers. By applying a hBN-assisted, contamination free, dry transfer process for CVD graphene, high-quality heterostructures with low doping densities and low strain variations are assembled. The Raman spectra of these pristine heterostructures are sensitive to substrate-induced doping and strain variations and are thus used to probe the suitability of the substrate material for potential high-quality graphene devices. We find that the flatness of the substrate material is a key figure for gaining, or preserving high-quality graphene.

  2. Addressing the high levels of psychological distress in law students through intentional assessment and feedback design in the first year law curriculum

    Rachael Field; Sally Kift


    A study of the Brain and Mind Institute released in 2009 established that more than one third of Australian law students suffer from psychological distress (BMRI, 2009). The psychological health of law students is therefore a critical issue for Australian legal education, and strategic change is necessary to address the stressful nature of studying law. This paper argues that intentional first year curriculum design has a critical role to play in addressing and preventing psychological distre...

  5. Explore-create-share study: An evaluation of teachers as curriculum innovators in engineering education

    Berry, Ayora

    included twenty-six teachers and data was collected pre-, mid-, and post-program using teacher surveys and a curriculum analysis instrument. The second study evaluated teachers' perceptions of the ECS model as a curriculum authoring tool and the quality of the curriculum units they developed. The study included sixty-two participants and data was collected post-program using teacher surveys and a curriculum analysis instrument. The third study evaluated teachers' experiences implementing ECS units in the classroom with a focus on identifying the benefits, challenges and solutions associated with project-based engineering in the classroom. The study included thirty-one participants and data was collected using an open-ended survey instrument after teachers completed implementation of the ECS curriculum unit. Results of these three studies indicate that teachers can be prepared to integrate engineering in the classroom using a CDB professional development model. Teachers reported an increase in engineering content knowledge, improved their self-efficacy in curriculum planning, and developed high quality instructional units that were aligned to engineering design practices and STEM educational standards. The ECS instructional model was acknowledged as a valuable tool for developing and implementing engineering education in the classroom. Teachers reported that ECS curriculum design aligned with their teaching goals, provided a framework to integrate engineering with other subject-area concepts, and incorporated innovative teaching strategies. After implementing ECS units in the classroom, teachers reported that the ECS model engaged students in engineering design challenges that were situated in a real world context and required the application of interdisciplinary content knowledge and skills. Teachers also reported a number of challenges related to scheduling, content alignment, and access to resources. In the face of these obstacles, teachers presented a number of

  6. The use of citation indicators to identify and support high-quality research in Poland.

    Pilc, Andrzej


    In large, mostly English-speaking countries, where the "critical mass" of scientists working in different subfields of science is achieved, the peer review system may be sufficient to assess the quality of scientific research. However, in smaller countries, outside the Anglo-American circle, it is important to introduce different systems to identify research of high quality. In Poland, a parametric system for assessing the quality of research has been introduced. It was largely based on the impact factor of scientific journals. While the use of this indicator to assess research quality is highly questionable, the implementation of the system in the Polish reality is even worse. Therefore it is important to change and improve the system currently used by the Ministry of Science and Higher Education to both evaluate and, more importantly, finance science in Poland. Here, a system based on three factors, i.e. the impact factor, the institutional h-index, and the institutional number of citations, is proposed. The scientific quality of institutions in Division VI: Medical Sciences of the Polish Academy of Sciences were evaluated and the results were compared with the existing system. Moreover, a method to identify high-quality researchers and institutions at the national level based on the quantity of highly cited papers is shown. Additionally, an attempt to identify the highest quality Polish research on an international level is proposed. This is based on the number of individual citations, the individual h-index, the number of publications, and the priority of the discovery.

  7. 從家課的質與量看香港課程改革的實施 The Quality and Quantity of Homework in Hong Kong Primary Schools: An Indicator of Curriculum Reform Implementation

    林智中 Chi-Chung Lam


    Full Text Available 華人地區深受傳統儒家文化影響,不少家長及教師都認同「勤有功、戲無益」、「有志者、事竟成」和「鐵柱磨成針」等傳統觀念。因此長期以來,香港學童都面對家課量多、家課深、長時間做家課的問題。2001年,香港特區政府推行教育改革,建議學校適當編排學生家課的數量,從而提升教與學的質素。為求了解香港學童家課的質與量是否因家課政策的實施而得以改善,本研究在香港10所小學進行調查,邀請各所學校其中一班五年級學生填寫問卷,統計完成家課的時間和家課類型,並訪問教師了解他們在家課設計、家課類型、家課功能等方面的考量。研究顯示,相對於課程改革之前,學生每天花在家課的時間的確減少;然而,大部分家課仍是紙筆練習,以鞏固課堂所學為主,較少有發展性的家課。分析這些研究結果背後的成因,有助於了解香港課程改革實施的狀況。Parents and teachers across Chinese societies mostly uphold the traditional belief of Confucianism that “hard work is the key to success.” As such, Hong Kong students have long been using much of their time doing lots of difficult homework. In 2001, curriculum reform was launched in Hong Kong, requesting schools and teachers to adjust the quantity and quality of homework assigned to students for the improvement of teaching and learning. The present study attempts to reveal the level of implementation of this homework policy. Ten primary schools participated in this study. One class of Grade 5 students in each school was chosen to complete a questionnaire for identifying the amount of time students spent on homework and the types of homework. Teachers of these classes were interviewed to find out how schools and teachers design and plan homework for their students. The study reveals that the time students spent on homework has decreased

  8. Selection of process parameters for producing high quality defatted sesame flour at pilot scale.

    Manikantan, M R; Sharma, Rajiv; Yadav, D N; Gupta, R K


    The present work was undertaken to study the effect of pearling duration, soaking time, steaming duration and drying temperature on the quality of sesame seeds and mechanically extracted partially defatted sesame cake. On the basis of quality attributes i.e. high protein, low crude fibre, low residual oil and low oxalic acid, the optimum process parameters were selected. The combination of 20 min of pearling duration, 15 min of soaking, 15 min of steaming at 100 kPa pressure and drying at 50 °C yielded high quality partially defatted protein rich sesame flour as compared to untreated defatted sesame flour. The developed high quality partially defatted protein rich sesame flour may be used in various food applications as a vital ingredient to increase the nutritional significance of the prepared foodstuffs.

  9. High Quality RNA Isolation from Leaf, Shell, Root Tissues and Callus of Hazelnut (Corylus avellana L.

    Hossein Khosravi


    Full Text Available Extraction of high quality RNA is a critical step in molecular genetics studies. Hazelnut is one of the most important nuts plants in the world. The presence of the taxol and other taxanes in hazelnut plant necessitates explaining their biosynthesis pathway and identifying the candidate genes. Therefore, an easy and practical method is necessary for RNA extraction from hazelnuts. Hazelnut has high levels of phenolic compounds. High amounts of polyphenolic and polysaccharide compounds in plants could be causing problems in RNA extraction procedures.  To avoid these problems, a simple and efficient method can be used based on cetyltrimethylammonium bromide (CTAB extraction buffer and lithium chloride for extraction of high quality RNA from different parts of hazelnut plant. Using this method, a high-quality RNA sample (light absorbed in the A260/A280 was 2.04

  11. Isolation of high quality RNA from pistachio (Pistacia vera L.) and other woody plants high in secondary metabolites.

    Moazzam Jazi, Maryam; Rajaei, Saideh; Seyedi, Seyed Mahdi


    The quality and quantity of RNA are critical for successful downstream transcriptome-based studies such as microarrays and RNA sequencing (RNA-Seq). RNA isolation from woody plants, such as Pistacia vera, with very high amounts of polyphenols and polysaccharides is an enormous challenge. Here, we describe a highly efficient protocol that overcomes the limitations posed by poor quality and low yield of isolated RNA from pistachio and various recalcitrant woody plants. The key factors that resulted in a yield of 150 μg of high quality RNA per 200 mg of plant tissue include the elimination of phenol from the extraction buffer, raising the concentration of β-mercaptoethanol, long time incubation at 65 °C, and nucleic acid precipitation with optimized volume of NaCl and isopropyl alcohol. Also, the A260/A280 and A260/A230 of extracted RNA were about 1.9-2.1and 2.2-2.3, respectively, revealing the high purity. Since the isolated RNA passed highly stringent quality control standards for sensitive reactions, including RNA sequencing and real-time PCR, it can be considered as a reliable and cost-effective method for RNA extraction from woody plants.

  12. Analysis of apple beverages treated with high-power ultrasound: a quality function deployment approach.

    Režek Jambrak, Anet; Šimunek, Marina; Grbeš, Franjo; Mandura, Ana; Djekic, Ilija


    The objective of this paper was to demonstrate application of quality function deployment in analysing effects of high power ultrasound on quality properties of apple juices and nectars. In order to develop a quality function deployment model, joint with instrumental analysis of treated samples, a field survey was performed to identify consumer preferences towards quality characteristics of juices/nectar. Based on field research, the three most important characteristics were 'taste' and 'aroma' with 28.5% of relative absolute weight importance, followed by 'odour' (16.9%). The quality function deployment model showed that the top three 'quality scores' for apple juice were treatments with amplitude 90 µm, 9 min treatment time and sample temperature 40 °C; 60 µm, 9 min, 60 °C; and 90 µm, 6 min, 40 °C. For nectars, the top three were treatments 120 µm, 9 min, 20 °C; 60 µm, 9 min, 60 °C; and A2.16 60 µm, 9 min, 20 °C. This type of quality model enables a more complex measure of large scale of different quality parameters. Its simplicity should be understood as its practical advantage and, as such, this tool can be a part of design quality when using novel preservation technologies. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

  16. Radiological clerkships as a critical curriculum component in radiology education

    Kourdioukova, Elena V.; Verstraete, Koenraad L.; Valcke, Martin


    Objective: The aim of this research was to explore the perceived value of clinical clerkships in the radiology curriculum as well as the impact of radiology clerkship on students' beliefs about the profession of radiology as a whole and as a career. Methods: This study is a sequel to a previous survey in which student perceptions about radiology curriculum components were investigated. The present study focuses on a further analysis of a subsection in this study, based on 14 statements about radiology clerkship and two statements about radiology as a career. Results: Perceived usefulness of the aspects of radiology clerkship as 'radiology examination', 'skills development' and 'diagnosis focus' were awarded the highest scores. The predict value of the subscale 'radiology examination' on the level of performance was very high (adjusted R 2 = 0.19, p < .001). Conclusion: Students expressed highly favorable evaluation of clerkship as a learning environment to learn to order and to interpret imaging studies as well as an unique possibility to attend various radiological examinations and to access to specific radiology software systems, as well as to get a better view on radiology and to improve image interpretation skills. This positive attitude towards clerkship is closely tied to students' beliefs about the profession of radiology as a whole. These aspects of dedicated radiology clerkship are crucial for effective and high-quality education as well as for the choice of radiology as a career.

  17. When high-volume PCI operators in high-volume hospitals move to lower volume hospitals-Do they still maintain high volume and quality of outcomes?

    Lu, Tsung-Hsueh; Li, Sheng-Tun; Liang, Fu-Wen; Lee, Jo-Chi; Yin, Wei-Hsian


    The aim of this quasi-experimental study was to examine whether high-volume percutaneous coronary intervention (PCI) operators still maintain high volume and quality of outcomes when they moved to lower volume hospitals. Systematic reviews have indicated that high-volume PCI operators and hospitals have higher quality outcomes. However, little is known on whether high PCI volume and high quality outcomes are mainly due to operator characteristics (i.e., skill and experience) and is portable across organizations or whether it is due to hospital characteristics (i.e., equipment, team, and management system) and is less portable. We used Taiwan National Health Insurance claims data 2000-2012 to identify 98 high-volume PCI operators, 10 of whom moved from one hospital to another during the study period. We compared the PCI volume, risk-adjusted mortality ratio, and major adverse cardiovascular event (MACE) ratio before and after moving. Of the 10 high-volume operators who moved, 6 moved from high- to moderate- or low-volume hospitals, with median annual PCI volumes (interquartile range) of 130 (117-165) in prior hospitals and 54 (46-84) in subsequent hospitals (the hospital the operator moved to), and the remaining 4 moved from high to high-volume hospitals, with median annual PCI volumes (interquartile range) of 151 (133-162) in prior hospitals and 193 (178-239) in subsequent hospitals. No significant differences were observed in the risk-adjusted mortality ratios and MACE ratios between high-volume operators and matched controls before and after moving. High-volume operators cannot maintain high volume when they moved from high to moderate or low-volume hospitals; however, the quality of care is maintained. High PCI volume and high-quality outcomes are less portable and more hospital bound. © 2017 Wiley Periodicals, Inc.

  18. A Narrative Review of High-Quality Literature on the Effects of Resident Duty Hours Reforms.

    Lin, Henry; Lin, Emery; Auditore, Stephanie; Fanning, Jon


    To summarize current high-quality studies evaluating the effect and efficacy of resident duty hours reforms (DHRs) on patient safety and resident education and well-being. The authors searched PubMed and Medline in August 2012 and again in May 2013 for literature (1987-2013) about the effects of DHRs. They assessed the quality of articles using the Medical Education Research Study Quality Instrument (MERSQI) scoring system. They considered randomized controlled trials (RCTs), partial RCTs, and all studies with a MERSQI score ≥ 14 to be "high-quality" methodology studies. A total of 72 high-quality studies met inclusion criteria. Most studies showed no change or slight improvement in mortality and complication rates after DHRs. Resident well-being was generally improved, but there was a perceived negative impact on education (knowledge acquisition, skills, and cognitive performance) following DHRs. Eleven high-quality studies assessed the impact of DHR interventions; all reported a neutral to positive impact. Seven high-quality studies assessed costs associated with DHRs and demonstrated an increase in hospital costs. The results of most studies that allow enough time for DHR interventions to take effect suggest a benefit to patient safety and resident well-being, but the effect on the quality of training remains unknown. Additional methodologically sound studies on the impact of DHRs are necessary. Priorities for future research include approaches to optimizing education and clinical proficiency and studies on the effect of intervention strategies on both education and patient safety. Such studies will provide additional information to help improve duty hours policies.

  19. How we developed a bioethics theme in an undergraduate medical curriculum.

    Ghias, Kulsoom; Ali, Syeda Kauser; Khan, Kausar S; Khan, Robyna; Khan, Murad M; Farooqui, Arshi; Nayani, Parvez


    The 5-year undergraduate medical curriculum at Aga Khan University integrates basic sciences with clinical and community health sciences. Multimodal strategies of teaching and learning, with an emphasis on problem-based learning, are utilized to equip students with knowledge, skills, behaviours, attitudes and values necessary for a high-calibre medical graduate. Bioethics teaching was introduced in the medical curriculum in 1988 and has since undergone several changes. In 2009, a multidisciplinary voluntary group began review of undergraduate bioethics teaching and invested over 350 man-hours in curricular revision. This involved formulating terminal objectives, delineating specific objectives and identifying instructional methodologies and assessment strategies appropriate for the contents of each objective. Innovative strategies were specially devised to work within the time constraints of the existing medical curriculum and importantly, to increase student interest and engagement. The new bioethics curriculum is designed to be comprehensive and robust, and strives to develop graduates who, in addition to being technically skilled and competent, are well-versed in the history and philosophy of ethics and bioethics and are ethical in their thinking and practice, especially in the context of a developing country like Pakistan where health indicators are among the worst in the region, and clinical practices are not effectively regulated to ensure quality of care.

  20. Certifying leaders? high-quality management practices and healthy organisations: an ISO-9000 based standardisation approach.

    Montano, Diego


    The present study proposes a set of quality requirements to management practices by taking into account the empirical evidence on their potential effects on health, the systemic nature of social organisations, and the current conceptualisations of management functions within the framework of comprehensive quality management systems. Systematic reviews and meta-analyses focusing on the associations between leadership and/or supervision and health in occupational settings are evaluated, and the core elements of an ISO 9001 standardisation approach are presented. Six major occupational health requirements to high-quality management practices are identified pertaining to communication processes, organisational justice, role clarity, decision making, social influence processes and management support. It is concluded that the quality of management practices may be improved by developing a quality management system of management practices that ensures not only conformity to product but also to occupational safety and health requirements. Further research may evaluate the practicability of the proposed approach.

  1. Modeling the Subjective Quality of Highly Contrasted Videos Displayed on LCD With Local Backlight Dimming

    Mantel, Claire; Bech, Søren; Korhonen, Jari


    Local backlight dimming is a technology aiming at both saving energy and improving visual quality on television sets. As the rendition of the image is specified locally, the numerical signal corresponding to the displayed image needs to be computed through a model of the display. This simulated...... signal can then be used as input to objective quality metrics. The focus of this paper is on determining which characteristics of locally backlit displays influence quality assessment. A subjective experiment assessing the quality of highly contrasted videos displayed with various local backlight......-dimming algorithms is set up. Subjective results are then compared with both objective measures and objective quality metrics using different display models. The first analysis indicates that the most significant objective features are temporal variations, power consumption (probably representing leakage...

  2. The effect of the amiodarone-warfarin interaction on anticoagulation quality in a single, high-quality anticoagulation center.

    White, Ryan D; Riggs, Kyle W; Ege, Ed J; Petroski, Gregory F; Koerber, Scott M; Flaker, Greg


    Clinical trials have reported a low time in therapeutic range (TTR) in patients with atrial fibrillation treated with both warfarin andamiodarone. These trials included centers and countries with both high and low TTRs. What is the impact of amiodarone on the TTR in a single, high-quality anticoagulation clinic? TTR was assessed in amiodarone and nonamiodarone-treated patients from a University anticoagulation clinic. Baseline characteristics between patients ever-taking or never-taking amiodarone were similar, except more amiodarone patients were smokers (19.5 vs. 6.1%, P = 0.0031). The TTR calculated from 8901international normalized ratios (INRs) in 249 nonamiodarone patients with a mean follow-up of 34 ± 20 months (mean INR 36 ± 18) was 66 ± 16.6% compared with 61.3 ± 16.2% (P = 0.111) from 1455 INRs in 41 amiodarone-treated patients with a mean follow-up of 28 ± 20 months (mean INR 35 ± 22). Factors associated with a low TTR were male sex (P = 0.0013), smoker (P = 0.0048), and amiodarone use (P = 0.0374). A second on-treatment analysis, in which the TTR was calculated only during amiodarone therapy, resulted in similar findings; however, amiodarone did not emerge as a predictor of a low TTR. In 11 patients, the TTR prior to amiodarone (54.5 ± 22.2%) was not significantly different in the first 3 months (54.6 ± 33.4%) or after 3 months (67.2 ± 33.7%) of amiodarone. In a single high-quality anticoagulation center, anticoagulation quality, as measured by the TTR, can be comparable in amiodarone and nonamiodarone-treated patients.

    Hoyles, Celia; Woodhouse, Geoffrey


    At a time when political interest in mathematics education is at its highest, this book demonstrates that the issues are far from straightforward. A wide range of international contributors address such questions as: What is mathematics, and what is it for? What skills does mathematics education need to provide as technology advances? What are the implications for teacher education? What can we learn from past attempts to change the mathematics curriculum? Rethinking the Mathematics Curriculum offers stimulating discussions, showing much is to be learnt from the differences in culture, national expectations, and political restraints revealed in the book. This accessible book will be of particular interest to policy makers, curriculum developers, educators, researchers and employers as well as the general reader.

  5. Combined microfluidization and ultrasonication: a synergistic protocol for high-efficient processing of SWCNT dispersions with high quality

    Luo, Sida, E-mail: [Beihang University, School of Mechanical Engineering and Automation (China); Liu, Tao, E-mail: [Florida State University, High-Performance Materials Institute (United States); Wang, Yong; Li, Liuhe [Beihang University, School of Mechanical Engineering and Automation (China); Wang, Guantao; Luo, Yun [China University of Geosciences, Center of Safety Research, School of Engineering and Technology (China)


    High-efficient and large-scale production of high-quality CNT dispersions is necessary for meeting the future needs to develop various CNT-based electronic devices. Herein, we have designed novel processing protocols by combining conventional ultrasonication process with a new microfluidization technique to produce high-quality SWCNT dispersions with improved processing efficiency. To judge the quality of SWCNT dispersions, one critical factor is the degree of exfoliation, which could be quantified by both geometrical dimension of the exfoliated nanotubes and percentage of individual tubes in a given dispersion. In this paper, the synergistic effect of the combined protocols was systematically investigated through evaluating SWCNT dispersions with newly developed characterization techniques, namely preparative ultracentrifuge method (PUM) and simultaneous Raman scattering and photoluminescence spectroscopy (SRSPL). The results of both techniques draw similar conclusions that as compared with either of the processes operated separately, a low-pass microfluidization followed by a reasonable duration of ultrasonication could substantially improve the processing efficiency to produce high-quality SWCNT dispersions with averaged particle length and diameter as small as ~600 and ~2 nm, respectively.Graphical abstract.

  8. Development of a high-quality cut-off wall using electrophoresis

    Kawachi, T.; Murahashi, H.


    Techniques to build a high-quality cut-off wall have been developed for storage facilities of low-level radioactive waste (LLW) as an emergency measures to prevent leakages. The cut-off wall is highly impermeable, nucleid-adsorptive and have long-term durability. Electrophoresis is used to form impermeable membrane of bentonite as main features of the cut-off wall. First of all, laboratory tests have been conducted to study ways of building barriers on site and to collect data on the barriers properties. Afterwards, on-site construction tests of a high-quality cut-off wall have been carried out. In this paper, we describe the process and results on the studies of the high-quality cut-off wall using electrophoresis

  14. High dose-rate brachytherapy source position quality assurance using radiochromic film

    Evans, M.D.C.; Devic, S.; Podgorsak, E.B.


    Traditionally, radiographic film has been used to verify high-dose-rate brachytherapy source position accuracy by co-registering autoradiographic and diagnostic images of the associated applicator. Filmless PACS-based clinics that do not have access to radiographic film and wet developers may have trouble performing this quality assurance test in a simple and practical manner. We describe an alternative method for quality assurance using radiochromic-type film. In addition to being easy and practical to use, radiochromic film has some advantages in comparison with traditional radiographic film when used for HDR brachytherapy quality assurance

  20. Can first-year medical students acquire quality improvement knowledge prior to substantial clinical exposure? A mixed-methods evaluation of a pre-clerkship curriculum that uses education as the context for learning.

    Brown, Allison; Nidumolu, Aditya; Stanhope, Alexandra; Koh, Justin; Greenway, Matthew; Grierson, Lawrence


    Quality Improvement (QI) training for health professionals is essential to strengthen health systems. However, QI training during medical school is constrained by students' lack of contextual understanding of the health system and an already saturated medical curriculum. The Program for Improvement in Medical Education (PRIME), an extracurricular offered at the Michael G. DeGroote School of Medicineat McMaster University (Hamilton, Canada), addresses these obstacles by having first-year medical students engage in QI by identifying opportunities for improvement within their own education. A sequential explanatory mixed-methods approach, which combines insights derived from quantitative instruments and qualitative interview methods, was used to examine the impact of PRIME on first-year medical students and the use of QI in the context of education. The study reveals that participation in PRIME increases both knowledge of, and comfort with, fundamental QI concepts, even when applied to clinical scenarios. Participants felt that education provided a meaningful context to learn QI at this stage of their training, and were motivated to participate in future QI projects to drive real-world improvements in the health system. Early exposure to QI principles that uses medical education as the context may be an effective intervention to foster QI competencies at an early stage and ultimately promote engagement in clinical QI. Moreover, PRIME also provides a mechanism to drive improvements in medical education. Future research is warranted to better understand the impact of education as a context for later engagement in clinical QI applications as well as the potential for QI methods to be translated directly into education. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Gómez, Juan Carlos Castro; Reátegui, Alina Del Carmen Egoavil; Flores, Julián Torres; Saavedra, Roberson Ramírez; Ruiz, Marianela Cobos; Correa, Sixto Alfredo Imán


    Myrciaria dubia is a main source of vitamin C for people in the Amazon region. Molecular studies of M. dubia require high-quality total RNA from different tissues. So far, no protocols have been reported for total RNA isolation from leaves of this species. The objective of this research was to develop protocols for extracting high-quality total RNA from leaves of M. dubia. Total RNA was purified following two modified protocols developed for leaves of other species (by Zeng and Yang, and by Reid et al.) and one modified protocol developed for fruits of the studied species (by Silva). Quantity and quality of purified total RNA were assessed by spectrophotometric and electrophoretic analysis. Additionally, quality of total RNA was evaluated with reverse-transcription polymerase chain reaction (RT-PCR). With these three modified protocols we were able to isolate high-quality RNA (A260nm/A280nm >1.9 and A260nm/A230nm >2.0). Highest yield was produced with the Zeng and Yang modified protocol (384±46µg ARN/g fresh weight). Furthermore, electrophoretic analysis showed the integrity of isolated RNA and the absence of DNA. Another proof of the high quality of our purified RNA was the successful cDNA synthesis and amplification of a segment of the M. dubia actin 1 gene. We report three modified protocols for isolation total RNA from leaves of M. dubia. The modified protocols are easy, rapid, low in cost, and effective for high-quality and quantity total RNA isolation suitable for cDNA synthesis and polymerase chain reaction.

    High quality beam generation project based on High-Tech Research Center Project, which has been approved by Ministry of Education, Culture, Sports, Science and Technology in 1999, has been conducted by advance research institute for science and engineering, Waseda University. In the project, laser photo-cathode RF-gun has been selected for the high quality electron beam source. RF cavities with low dark current, which were made by diamond turning technique, have been successfully manufactured. The low emittance electron beam was realized by choosing the modified laser injection technique. The obtained normalized emmitance was about 3 m.mrad at 100 pC of electron charge. The soft x-ray beam generation with the energy of 370 eV, which is in the energy region of so-called water window, by inverse Compton scattering has been performed by the collision between IR laser and the low emmitance electron beams.

  5. The Barriers to High-Quality Inpatient Pain Management: A Qualitative Study.

    Lin, Richard J; Reid, M Carrington; Liu, Lydia L; Chused, Amy E; Evans, Arthur T


    The current literature suggests deficiencies in the quality of acute pain management among general medical inpatients. The aim of this qualitative study is to identify potential barriers to high-quality acute pain management among general medical inpatients at an urban academic medical center during a 2-year period. Data are collected using retrospective chart reviews, survey questionnaires, and semistructured, open-ended interviews of 40 general medical inpatients who have experienced pain during their hospitalization. Our results confirm high prevalence and disabling impacts of pain and significant patient- and provider-related barriers to high-quality acute pain management. We also identify unique system-related barriers such as time delay and pain management culture. Efforts to improve the pain management experience of general medical inpatients will need to address all these barriers. © The Author(s) 2014.

  6. Quality Evaluation of Potentilla fruticosa L. by High Performance Liquid Chromatography Fingerprinting Associated with Chemometric Methods.

    Liu, Wei; Wang, Dongmei; Liu, Jianjun; Li, Dengwu; Yin, Dongxue


    The present study was performed to assess the quality of Potentilla fruticosa L. sampled from distinct regions of China using high performance liquid chromatography (HPLC) fingerprinting coupled with a suite of chemometric methods. For this quantitative analysis, the main active phytochemical compositions and the antioxidant activity in P. fruticosa were also investigated. Considering the high percentages and antioxidant activities of phytochemicals, P. fruticosa samples from Kangding, Sichuan were selected as the most valuable raw materials. Similarity analysis (SA) of HPLC fingerprints, hierarchical cluster analysis (HCA), principle component analysis (PCA), and discriminant analysis (DA) were further employed to provide accurate classification and quality estimates of P. fruticosa. Two principal components (PCs) were collected by PCA. PC1 separated samples from Kangding, Sichuan, capturing 57.64% of the variance, whereas PC2 contributed to further separation, capturing 18.97% of the variance. Two kinds of discriminant functions with a 100% discrimination ratio were constructed. The results strongly supported the conclusion that the eight samples from different regions were clustered into three major groups, corresponding with their morphological classification, for which HPLC analysis confirmed the considerable variation in phytochemical compositions and that P. fruticosa samples from Kangding, Sichuan were of high quality. The results of SA, HCA, PCA, and DA were in agreement and performed well for the quality assessment of P. fruticosa. Consequently, HPLC fingerprinting coupled with chemometric techniques provides a highly flexible and reliable method for the quality evaluation of traditional Chinese medicines.

  20. Developing Quality Control Procedures to Sustain a Supply of High Quality Blood for Mass Rearing Tsetse Flies

    De Beer, C J; Venter, G J; Potgieter, F T [ARC-Onderstepoort Veterinary Institute, Old Soutpans Road, Private Bag X05, 0110 Onderstepoort (South Africa)


    Mass rearing tsetse flies Glossina spp. is dependent on the sustained availability of a high quality blood diet. In any mass rearing facility, the logistics for obtaining sterile, high quality fresh blood is challenging. An added complication is the influence of potential chemical, physical and microbiological elements present in the blood of donors, as well as contamination during collection, handling and storage. Research at the Agricultural Research Council - Onderstepoort Veterinary institute (ARC-OVI) is directed towards the development of quality control procedures for the supply of the in vitro diet used to maintain productive colonies of Glossina brevipalpis Newstead and Glossina austeni Newstead. Factors that may influence the blood diet, e.g. defibrination, feeding times, collection of blood in anticoagulants, treatment of blood with taste stimuli, repeated freezing and thawing of blood, effect of bovine growth hormones, and also a preference for bovine or porcine blood were tested. A 25 day bioassay was used to determine the effects of these factors on tsetse survival and reproduction. Defibrination of the blood for 10 to 15 minutes gave the best results for both species. It was found that G. brevipalpis should be fed three times per week for 5 minutes each time, and G. austeni three times per week for 10 minutes. Heparin, acid citrate dextrose (ACD), citric acid, citrate phosphate dextrose adenine (CPDA) and a combination of sodium citrate and citric acid were effective anticoagulants in the blood diets of G. brevipalpis and G. austeni. Blood treated with inosine triphosphate (ITP) gave the highest quality factor (QFC) values for both G. austeni and G. brevipalpis. Repeated freezing and thawing of blood definitely affects pupal production negatively; G. brevipalpis especially produced significantly smaller pupae. A premixed diet of equal amounts of bovine and porcine blood was found to be best suited for G. brevipalpis, and for G. austeni a mixture of
