Breakdown Degradation Associated with Elementary Screw Dislocations in 4H-SiC P(+)N Junction Rectifiers

NASA Technical Reports Server (NTRS)

Neudeck, P. G.; Huang, W.; Dudley, M.

1998-01-01

It is well-known that SiC wafer quality deficiencies are delaying the realization of outstandingly superior 4H-SiC power electronics. While efforts to date have centered on eradicating micropipes (i.e., hollow core super-screw dislocations with Burgers vector greater than 2c), 4H-SiC wafers and epilayers also contain elementary screw dislocations (i.e., Burgers vector = lc with no hollow core) in densities on the order of thousands per sq cm, nearly 100-fold micropipe densities. This paper describes an initial study into the impact of elementary screw dislocations on the reverse-bias current-voltage (I-V) characteristics of 4H-SiC p(+)n diodes. First, Synchrotron White Beam X-ray Topography (SWBXT) was employed to map the exact locations of elementary screw dislocations within small-area 4H-SiC p(+)n mesa diodes. Then the high-field reverse leakage and breakdown properties of these diodes were subsequently characterized on a probing station outfitted with a dark box and video camera. Most devices without screw dislocations exhibited excellent characteristics, with no detectable leakage current prior to breakdown, a sharp breakdown I-V knee, and no visible concentration of breakdown current. In contrast devices that contained at least one elementary screw dislocation exhibited a 5% to 35% reduction in breakdown voltage, a softer breakdown I-V knee, and visible microplasmas in which highly localized breakdown current was concentrated. The locations of observed breakdown microplasmas corresponded exactly to the locations of elementary screw dislocations identified by SWBXT mapping. While not as detrimental to SiC device performance as micropipes, the undesirable breakdown characteristics of elementary screw dislocations could nevertheless adversely affect the performance and reliability of 4H-SiC power devices.

Comparison of DMSP and SECS region-1 and region-2 ionospheric current boundary

NASA Astrophysics Data System (ADS)

Weygand, J. M.; Wing, S.

2016-06-01

The region-1 and region-2 boundary has traditionally been identified using data from a single spacecraft crossing the auroral region and measuring the large scale changes in the cross track magnetic field. With data from the AUTUMN, CANMOS, CARISMA, GIMA, DTU MGS, MACCS, McMAC, STEP, THEMIS, and USGS ground magnetometer arrays we applied a state-of-art technique based on spherical elementary current system (SECS) method developed by Amm and Viljanen (1999) in order to calculate maps of region-1 and region-2 current system over the North American and Greenland auroral region. Spherical elementary current (SEC) amplitude (proxy for vertical currents) maps can be inferred at 10 s temporal resolution, ~1.5° geographic latitude (Glat), and 3.5° geographic longitude (Glon) spatial resolution. We compare the location of the region-1 and region-2 boundary obtained by the DMSP spacecraft with the region-1 and region-2 boundary observed in the SEC current amplitudes. We find that the boundaries typically agree within 0.2°±1.3°. These results indicate that the location of the region-1 and region-2 boundary can reasonably be determined from ground magnetometer data. The SECS maps represent a value-added product from the magnetometer database and can be used for contextual interpretation in conjunction with other missions as well as help with our understanding of magnetosphere-ionosphere coupling mechanisms using the ground arrays and the magnetospheric spacecraft data.

Attitudes of pre-service elementary teachers towards science: A cross-national study between the United States of America and Turkey

NASA Astrophysics Data System (ADS)

Buldu, Nihal

Preservice elementary teachers' attitudes toward science have been the subject of investigation by science educators for decades. Many of the recent attempts pertaining to preservice elementary teachers by science educators have focused on the effects of science method courses on the attitudes and relationships between attitudes and other variables. The research literature lacks studies that compare attitudes of preservice elementary teachers toward science across two or more nations. The current study investigated the attitudes of preservice elementary teachers toward science in the U.S. and Turkey in order to see if there is a difference between the U.S. and Turkish preservice elementary teachers' attitudes toward science, and to investigate whether variables such as gender and the grade the preservice teachers wish to teach make a difference in preservice elementary teachers' attitudes towards science. The sample consisted of 1144 preservice elementary teachers. Of the 1144 preservice elementary teachers for whom complete information is available, it is known that 371 preservice elementary teachers were from the U.S. and 773 were from Turkey. The attitudes of preservice elementary teachers in the U.S. and Turkey were assessed by the data gathered using Turkish and American Preservice Elementary Teachers Attitude Scale (TAPETAS). This scale is a revised version of the Modified Fennema Sherman Attitude Scale (Doepken, Lawsky, and Padwa, 1999). Results of the current study indicated that both U.S. and Turkish preservice elementary teachers had positive attitudes toward science. However, U.S. preservice elementary teachers had more confidence in science. They found science more useful than their Turkish peers. They had more positive attitudes towards their previous science teachers and were less likely to stereotype science as a male domain. There were not any significant differences between the U.S. preservice elementary teachers due to gender and the grade they wanted to teach. There were significant differences between the Turkish preservice teachers due to gender. Discussion of the findings, implications of the study and recommendations for further research were presented.

Comparison of two different Radiostereometric analysis (RSA) systems with markerless elementary geometrical shape modeling for the measurement of stem migration.

PubMed

Li, Ye; Röhrl, Stephan M; Bøe, B; Nordsletten, Lars

2014-09-01

Radiostereometric analysis (RSA) is the gold standard of measurement for in vivo 3D implants migration. The aim of this study was to evaluate the in vivo precision of 2 RSA marker-based systems compared with that of marker-free, elementary geometrical shape modeling RSA. Stem migration was measured in 50 patients recruited from an on-going Randomized Controlled Trial. We performed marker-based analysis with the Um RSA and RSAcore systems and compared these results with those of the elementary geometrical shape RSA. The precision for subsidence was 0.118 mm for Um RSA, 0.141 mm for RSAcore, and 0.136 mm for elementary geometrical shape RSA. The precision for retroversion was 1.3° for elementary geometrical shape RSA, approximately 2-fold greater than that for the other methods. The intraclass correlation coefficient between the marker-based systems and elementary geometrical shape RSA was approximately 0.5 for retroversion. All 3 methods yielded ICCs for subsidence and varus-valgus rotation above 0.9. We found an excellent correlation between marker-based RSA and elementary geometrical shape RSA for subsidence and varus-valgus rotation, independent of the system used. The precisions for out-of-plane migration were inferior for elementary geometrical shape RSA. Therefore, as a mechanism of failure, retroversion may be more difficult to detect early. This is to our knowledge the first study to compare different RSA systems with or without markers on the implant. Marker-based RSA has high precision in all planes, independent of the system used. Elementary geometrical shape RSA is inferior in out-of-plane migration. Copyright © 2014 Elsevier Ltd. All rights reserved.

Relative locality and the soccer ball problem

DOE Office of Scientific and Technical Information (OSTI.GOV)

Amelino-Camelia, Giovanni; Freidel, Laurent; Smolin, Lee

We consider the behavior of macroscopic bodies within the framework of relative locality [G. Amelino-Camelia, L. Freidel, J. Kowalski-Glikman, and L. Smolin, arXiv:1101.0931]. This is a recent proposal for Planck scale modifications of the relativistic dynamics of particles which are described as arising from deformations in the geometry of momentum space. We consider and resolve a common objection against such proposals, which is that, even if the corrections are small for elementary particles in current experiments, they are huge when applied to composite systems such as soccer balls, planets, and stars, with energies E{sub macro} much larger than M{sub P}.more » We show that this soccer ball problem does not arise within the framework of relative locality because the nonlinear effects for the dynamics of a composite system with N elementary particles appear at most of order E{sub macro}/N{center_dot}M{sub P}.« less

Elementary teachers past experiences: A narrative study of the past personal and professional experiences of elementary teachers who use science to teach math and reading

NASA Astrophysics Data System (ADS)

Acre, Andrea M.

This qualitative study investigated the experiences of four elementary teachers who have elected to use science to teach math and reading/language arts in an attempt to identify what motivates them to do so. Identifying what experiences have motivated these teachers to go against the gain and teach elementary science in this current era of high-stakes tests is of the upmost importance given that science is being eliminated from the elementary curriculum and it is during the elementary years that students' nurture and develop their interest in science. Additionally, the United States is failing to produce enough college graduates in STEM areas to fill the thousands of STEM jobs each year. Through a review of the literature, the past trends and current trends of elementary science education were explored as well as teacher training. Furthermore, the literature reviewed inquiry teaching which is considered to be the most effective teaching method when teaching science at any level. Using John Dewey's Interest and Effort Relationship Theory and the Self-Determination Motivation Theory to guide this study, there were five prominent themes which emerged from the reconstructed stories of the four teachers: positive experiences with science, neutral/negative experiences with science, seeks meaningful professional development, influence and support from others, and regret/wants to do more.

Practical Quantum Realization of the Ampere from the Elementary Charge

NASA Astrophysics Data System (ADS)

Brun-Picard, J.; Djordjevic, S.; Leprat, D.; Schopfer, F.; Poirier, W.

2016-10-01

One major change of the future revision of the International System of Units is a new definition of the ampere based on the elementary charge e . Replacing the former definition based on Ampère's force law will allow one to fully benefit from quantum physics to realize the ampere. However, a quantum realization of the ampere from e , accurate to within 10-8 in relative value and fulfilling traceability needs, is still missing despite the many efforts made for the development of single-electron tunneling devices. Starting again with Ohm's law, applied here in a quantum circuit combining the quantum Hall resistance and Josephson voltage standards with a superconducting cryogenic amplifier, we report on a practical and universal programmable quantum current generator. We demonstrate that currents generated in the milliampere range are accurately quantized in terms of e fJ (fJ is the Josephson frequency) with measurement uncertainty of 10-8. This new quantum current source, which is able to deliver such accurate currents down to the microampere range, can greatly improve the current measurement traceability, as demonstrated with the calibrations of digital ammeters. In addition, it opens the way to further developments in metrology and in fundamental physics, such as a quantum multimeter or new accurate comparisons to single-electron pumps.

Elementary diagrams in nuclear and neutron matter

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wiringa, R.B.

1995-08-01

Variational calculations of nuclear and neutron matter are currently performed using a diagrammatic cluster expansion with the aid of nonlinear integral equations for evaluating expectation values. These are the Fermi hypernetted chain (FHNC) and single-operator chain (SOC) equations, which are a way of doing partial diagram summations to infinite order. A more complete summation can be made by adding elementary diagrams to the procedure. The simplest elementary diagrams appear at the four-body cluster level; there is one such E{sub 4} diagram in Bose systems, but 35 diagrams in Fermi systems, which gives a level of approximation called FHNC/4. We developedmore » a novel technique for evaluating these diagrams, by computing and storing 6 three-point functions, S{sub xyz}(r{sub 12}, r{sub 13}, r{sub 23}), where xyz (= ccd, cce, ddd, dde, dee, or eee) denotes the exchange character at the vertices 1, 2, and 3. All 35 Fermi E{sub 4} diagrams can be constructed from these 6 functions and other two-point functions that are already calculated. The elementary diagrams are known to be important in some systems like liquid {sup 3}He. We expect them to be small in nuclear matter at normal density, but they might become significant at higher densities appropriate for neutron star calculations. This year we programmed the FHNC/4 contributions to the energy and tested them in a number of simple model cases, including liquid {sup 3}He and Bethe`s homework problem. We get reasonable, but not exact agreement with earlier published work. In nuclear and neutron matter with the Argonne v{sub 14} interaction these contributions are indeed small corrections at normal density and grow to only 5-10 MeV/nucleon at 5 times normal density.« less

Making Earth Science Relevant in the K-8 Classroom. The Development of an Instructional Soils Module for Pre-Service Elementary Teachers Using the Next Generation Science Standards

NASA Astrophysics Data System (ADS)

Baldwin, K. A.; Hauge, R.; Dechaine, J. M.; Varrella, G.; Egger, A. E.

2013-12-01

The development and adoption of the Next Generation Science Standards (NGSS) raises a challenge in teacher preparation: few current teacher preparation programs prepare students to teach science the way it is presented in the NGSS, which emphasize systems thinking, interdisciplinary science, and deep engagement in the scientific process. In addition, the NGSS include more geoscience concepts and methods than previous standards, yet this is a topic area in which most college students are traditionally underprepared. Although nationwide, programmatic reform is needed, there are a few targets where relatively small, course-level changes can have a large effect. One of these targets is the 'science methods' course for pre-service elementary teachers, a requirement in virtually all teacher preparation programs. Since many elementary schools, both locally and across the country, have adopted a kit based science curriculum, examining kits is often a part of a science methods course. Unfortunately, solely relying on a kit based curriculum may leave gaps in science content curriculum as one prepares teachers to meet the NGSS. Moreover, kits developed at the national level often fall short in connecting geoscientific content to the locally relevant societal issues that engage students. This highlights the need to train pre-service elementary teachers to supplement kit curriculum with inquiry based geoscience investigations that consider relevant societal issues, promote systems thinking and incorporate connections between earth, life, and physical systems. We are developing a module that teaches geoscience concepts in the context of locally relevant societal issues while modeling effective pedagogy for pre-service elementary teachers. Specifically, we focus on soils, an interdisciplinary topic relevant to multiple geoscience-related societal grand challenges (e.g., water, food) that is difficult to engage students in. Module development is funded through InTeGrate, NSF's STEP Center in the geosciences. The module goals are: 1) Pre-service teachers will apply classification methods, testing procedures and interdisciplinary systems thinking to analyze and evaluate a relevant societal issue in the context of soils, 2) Pre-service teachers will design, develop, and facilitate a standards-based K-8 soils unit, incorporating a relevant broader societal issue that applies authentic geoscientific data, and incorporates geoscientific habits of mind. In addition, pre-service teachers will look toward the NGSS and align activities with content standards, systems thinking, and science and engineering practices. This poster will provide an overview of module development to date as well as a summary of pre-semester survey results indicating pre-service elementary teachers' ideas (beliefs, attitudes, preconceptions, and content knowledge) about teaching soils, and making science relevant in a K-8 classroom.

Investigating the Self-Perceived Science Teaching Needs of Local Elementary Educators

NASA Astrophysics Data System (ADS)

Carver, Cynthia G.

Elementary teachers in one school system have expressed low self-efficacy teaching science and desire more support teaching science. However, little research has been conducted on how best to meet these teachers' needs. The theories of perceived self-efficacy, social cognition, and behaviorism make up the conceptual framework of this study. The focus of this qualitative project study was on the needs of local elementary educators. These teachers were asked what they felt they needed most to be more effective science educators. The methodology of phenomenology was used in this study in which local elementary teachers were questioned in focus groups regarding their own science teaching efficacy and perceived needs. Using inductive analysis, data were coded for links to discussion questions as well as any additional patterns that emerged. Findings indicated that local elementary teachers desire improved communication among administrators and teachers as well as better science content support and training. Focus group participants agreed that teacher self-efficacy affects the time spent, effort toward, and quality of elementary science education. Using the results of the study, a science mentor program was developed to support the needs of elementary teachers and increase teacher self-efficacy, thus improving local elementary science education. Implications for positive social change include the development and support of elementary science programs in other school systems with the goal of improving science education for elementary students.

THE PHYSICS OF ELEMENTARY PARTICLES AND FIELDS: Topological aspects in a two-component Bose condensed system in a neutron star

NASA Astrophysics Data System (ADS)

Ren, Ji-Rong; Guo, Heng

2009-08-01

By making use of Duan-Ge's decomposition theory of gauge potential and the topological current theory proposed by Prof. Duan Yi-Shi, we study a two-component superfluid Bose condensed system, which is supposed to be realized in the interior of neutron stars in the form of the coexistence of a neutron superfluid and a protonic superconductor. We propose that this system possesses vortex lines. The topological charges of the vortex lines are characterized by the Hopf indices and the Brower degrees of ø-mapping.

We describe a 2 mg artificial elementary eye whose structure and functionality is inspired by compound eye ommatidia. Its optical sensitivity and electronic architecture are sufficient to generate the required signals for the measurement of local optic flow vectors in multiple directions. Multiple elementary eyes can be assembled to create a compound vision system of desired shape and curvature spanning large fields of view. The system configurability is validated with the fabrication of a flexible linear array of artificial elementary eyes capable of extracting optic flow over multiple visual directions. © 2015 The Author(s).

Observation of spinon spin currents in one-dimensional spin liquid

Hirobe, Daichi; Sato, Masahiro; Kawamata, Takayuki; Shiomi, Yuki; Uchida, Ken-Ichi; Iguchi, Ryo; Koike, Yoji; Maekawa, Sadamichi; Saitoh, Eiji

To date, two types of spin current have been explored experimentally: conduction-electron spin current and spin-wave spin current. Here, we newly present spinon spin current in quantum spin liquid. An archetype of quantum spin liquid is realized in one-dimensional spin-1/2 chains with the spins coupled via antiferromagnetic interaction. Elementary excitation in such a system is known as a spinon. Theories have predicted that the correlation of spinons reaches over a long distance. This suggests that spin current may propagate via one-dimensional spinons even in spin liquid states. In this talk, we report the experimental observation that a spin liquid in a spin-1/2 quantum chain generates and conveys spin current, which is attributed to spinon spin current. This is demonstrated by observing an anisotropic negative spin Seebeck effect along the spin chains in Sr2CuO3. The results show that spin current can flow via quantum fluctuation in spite of the absence of magnetic order, suggesting that a variety of quantum spin systems can be applied to spintronics.

Developing a visual sensing system, complete with motion processing hardware and software would have many applications to current technology. It could be mounted on many autonomous vehicles to provide information about the navigational environment, as well as obstacle avoidance features. Incorporating the motion processing capabilities into the sensor requires a new approach to the algorithm implementation. This research, and that of many others, have turned to nature for inspiration. Elementary motion detector (EMD) cells are involved in a biological preprocessing network to provide information to the motion processing lobes of the house degrees y Musca domestica. This paper describes the response of the photoreceptor inputs to the EMDs. The inputs to the EMD components are tested as they are stimulated with varying image primitives. This is the first of many steps in characterizing the EMD response to image primitives.

Low cost, power and bandwidth UGS can be used to fill the growing need for surveillance in remote environments. In particular, linear and 2D thermal sensor systems can run for up to months at a time and their deployment can be scaled to suit the size of the mission. Thermal silhouette profilers like Brimrose's SPOT system reduce power and bandwidth requirements by performing elementary classification and only transmitting binary data using optimized compression methods. These systems satisfy the demands for an increasing number of surveillance operations where reduced bandwidth and power consumption are mission critical.

Elementary teachers' acquisition of science knowledge: Case-studies and implications for teaching preparation

NASA Astrophysics Data System (ADS)

Stein, Morton

Elementary school is a key time for students to develop their understanding of basic science concepts as well as their attitudes towards science and science learning. Yet many elementary teachers do not feel comfortable teaching science; as a result, they are likely to devote less time on that subject and to be less effective as science teachers. The literature suggests that weaknesses in elementary teachers' knowledge of science could be a main cause of this problem and, furthermore, that current elementary teacher preparation programs have contributed to this weakness. This study aims at gaining more knowledge about how elementary teachers who are successful in teaching science have acquired their science content knowledge and how such knowledge could be best acquired, with the ultimate goal of informing the design of more effective elementary teacher preparation programs. More specifically, this study addresses the following research questions: Which science learning experiences for elementary teachers seem most conducive to develop the kind of science content knowledge and pedagogical content knowledge needed to support the teaching of science as called for by the most recent national and state standards? Which of these experiences should be included in elementary teacher preparation programs, and how? The core of this study consists of case studies of eight elementary school teachers who were identified as successful in teaching science. These subjects were selected so as to ensure differences in their teacher preparation programs, as well as gender and years of teaching experience. Information about each teacher's self-efficacy and motivation with respect to teaching science, history of pre-service and in-service preparation with respect to science, and how his/her current science knowledge was acquired, was sought through a series of interviews with each subject and triangulated with data collected from other sources. A cross-case analysis revealed some interesting similarities and differences in how these successful elementary science teachers developed their science knowledge, and identified the following main sources of science learning opportunities: (a) science content courses; (b) methods courses; (c) student teaching; (d) in-service workshops; (e) opportunities to work with colleagues on the design and/or delivery of science units. Based on what was learned from these case studies, a preliminary set of recommendations to improve elementary teacher's science learning opportunities was identified. Two focus groups were held---one with elementary teachers and another with teacher educators---to share these preliminary recommendations and gather feedback and additional suggestions. Informed by the information gathered in these focus groups, a final set of recommendations to improve elementary teacher's preparation to teach science was articulated.

A Smart Voltage and Current Monitoring System for Three Phase Inverters Using an Android Smartphone Application

PubMed Central

Mnati, Mohannad Jabbar; Van den Bossche, Alex; Chisab, Raad Farhood

2017-01-01

In this paper, a new smart voltage and current monitoring system (SVCMS) technique is proposed. It monitors a three phase electrical system using an Arduino platform as a microcontroller to read the voltage and current from sensors and then wirelessly send the measured data to monitor the results using a new Android application. The integrated SVCMS design uses an Arduino Nano V3.0 as the microcontroller to measure the results from three voltage and three current sensors and then send this data, after calculation, to the Android smartphone device of an end user using Bluetooth HC-05. The Arduino Nano V3.0 controller and Bluetooth HC-05 are a cheap microcontroller and wireless device, respectively. The new Android smartphone application that monitors the voltage and current measurements uses the open source MIT App Inventor 2 software. It allows for monitoring some elementary fundamental voltage power quality properties. An effort has been made to investigate what is possible using available off-the-shelf components and open source software. PMID:28420132

Elementary GLOBE: Inquiring About the Earth System Through Elementary Student Investigations

NASA Astrophysics Data System (ADS)

Henderson, S.; Hatheway, B.; Gardiner, L.; Gallagher, S.

2006-12-01

Elementary GLOBE was designed to introduce K-4 students to the study of Earth System Science (ESS). Elementary GLOBE forms an instructional unit comprised of five modules that address ESS and interrelated subjects including weather, hydrology, seasons, and soils. Each Elementary GLOBE module contains a science based storybook, classroom learning activities that complement the science content covered in each book, and teacher's notes. The storybooks explore a component of the Earth system and the associated classroom learning activities provide students with a meaningful introduction to technology, a basic understanding of the methods of inquiry, and connection to math and literacy skills. The science content in the books and activities serves as a springboard to GLOBE's scientific protocols. All Elementary GLOBE materials are freely downloadable (www.globe.gov/elementaryglobe) The use of science storybooks with elementary students has proven to be an effective practice in exposing students to science content while providing opportunities for students to improve their reading, writing, and oral communication skills. The Elementary GLOBE storybooks portray kids asking questions about the natural world, doing science investigations, and exploring the world around them. Through the storybook characters, scientific inquiry is modeled for young learners. The associated learning activities provide opportunities for students to practice science inquiry and investigation skills, including observation, recording, measuring, etc. Students also gain exposure and increase their comfort with different tools that scientists use. The learning activities give students experiences with asking questions, conducting scientific investigations, and scientific journaling. Elementary GLOBE fills an important niche in K-4 instruction. The international GLOBE Program brings together students, teachers, and scientists with the basic goals of increasing scientific understanding of the Earth, supporting improved student achievement in science and math, and enhancing environmental awareness. NASA provides the primary source of funding for GLOBE.

Hanley, Sean; Ringwalt, Chris; Ennett, Susan T.; Vincus, Amy A.; Bowling, J. Michael; Haws, Susan W.; Rohrbach, Louise A.

2010-01-01

Current guidelines for school-based substance use prevention suggest that prevention efforts should begin in elementary grades, before students begin using substances. Previous research suggests, however, that the use of evidence-based curricula in these grades may be low. Using a 2005 survey of public school districts in the U.S. that include elementary grades (n=1563), we assessed the prevalence of elementary curricula use, particularly those designated as evidence-based. We found that although 72% of districts administer a substance use prevention curriculum to their elementary students, only about 35% are using one that is evidence-based and only about 14% are using an evidence-based curriculum more so than any other prevention curriculum. We present prevalence estimates for specific evidence-based curricula and conclude by discussing possible reasons for and implications of our findings. PMID:21038763

2016-01-01

Purpose This study describes the development and pilot testing of the Observational System for Recording Physical Activity-Elementary School (OSRAC-E) version. Methods This system was developed to observe and document the levels and types of physical activity and physical and social contexts of physical activity in elementary school students during the school day. Inter-observer agreement scores and summary data were calculated. Results All categories had Kappa statistics above 0.80, with the exception of the activity initiator category. Inter-observer agreement scores were 96% or greater. The OSRAC-E was shown to be a reliable observation system that allows researchers to assess physical activity behaviors, the contexts of those behaviors, and the effectiveness of physical activity interventions in the school environment. Conclusion The OSRAC-E can yield data with high interobserver reliability and provide relatively extensive contextual information about physical activity of students in elementary schools.

Moura, Ricardo; Wood, Guilherme; Pinheiro-Chagas, Pedro; Lonnemann, Jan; Krinzinger, Helga; Willmes, Klaus; Haase, Vitor Geraldi

2013-11-01

Transcoding between numerical systems is one of the most basic abilities acquired by children during their early school years. One important topic that requires further exploration is how mathematics proficiency can affect number transcoding. The aim of the current study was to investigate transcoding abilities (i.e., reading Arabic numerals and writing dictation) in Brazilian children with and without mathematics difficulties, focusing on different school grades. We observed that children with learning difficulties in mathematics demonstrated lower achievement in number transcoding in both early and middle elementary school. In early elementary school, difficulties were observed in both the basic numerical lexicon and the management of numerical syntax. In middle elementary school, difficulties appeared mainly in the transcoding of more complex numbers. An error analysis revealed that the children with mathematics difficulties struggled mainly with the acquisition of transcoding rules. Although we confirmed the previous evidence on the impact of working memory capacity on number transcoding, we found that it did not fully account for the observed group differences. The results are discussed in the context of a maturational lag in number transcoding ability in children with mathematics difficulties. Copyright © 2013 Elsevier Inc. All rights reserved.

Place-based Learning About Climate with Elementary GLOBE

NASA Astrophysics Data System (ADS)

Hatheway, B.; Gardiner, L. S.; Harte, T.; Stanitski, D.; Taylor, J.

2017-12-01

Place-based education - helping students make connections between themselves, their community, and their local environment - is an important tool to help young learners understand their regional climate and start to learn about climate and environmental change. Elementary GLOBE storybooks and learning activities allow opportunities for place-based education instructional strategies about climate. In particular, two modules in the Elementary GLOBE unit - Seasons and Climate - provide opportunities for students to explore their local climate and environment. The storybooks and activities also make connections to other parts of elementary curriculum, such as arts, geography, and math. Over the long term, place-based education can also encourage students to be stewards of their local environment. A strong sense of place may help students to see themselves as stakeholders in their community and its resilience. In places that are particularly vulnerable to the impacts of climate and environmental change and the economic, social, and environmental tradeoffs of community decisions, helping young students developing a sense of place and to see the connection between Earth science, local community, and their lives can have a lasting impact on how a community evolves for decades to come. Elementary GLOBE was designed to help elementary teachers (i.e., grades K-4) integrate Earth system science topics into their curriculum as they teach literacy skills to students. This suite of instructional materials includes seven modules. Each module contains a science-based storybook and learning activities that support the science content addressed in the storybooks. Elementary GLOBE modules feature air quality, climate, clouds, Earth system, seasons, soil, and water. New eBooks allow students to read stories on computers or tablets, with the option of listening to each story with an audio recording. A new Elementary GLOBE Teacher Implementation Guide, published in 2017, provides educators with information and strategies how Elementary GLOBE modules can be effectively applied in classrooms, how Elementary GLOBE modules are aligned with national standards, and how student literacy and science inquiry skills can be strengthened while learning about the Earth system.

The system uses simultaneously a wearable sensor network for each individual and premise-embedded sensors specific for each environment. The paper demonstrates the benefits of using complementary information from two types of mobility sensors: visual flow-based image analysis and an accelerometer-based wearable network. The paper provides results for indoor recognition of several elementary poses and outdoor recognition of complex movements. Instead of complete system description, particular attention was drawn to a polar histogram-based method of visual pose recognition, complementary use and synchronization of the data from wearable and premise-embedded networks and an automatic danger detection algorithm driven by two premise- and subject-related databases. The novelty of our approach also consists in feeding the databases with real-life recordings from the subject, and in using the dynamic time-warping algorithm for measurements of distance between actions represented as elementary poses in behavioral records. The main results of testing our method include: 95.5% accuracy of elementary pose recognition by the video system, 96.7% accuracy of elementary pose recognition by the accelerometer-based system, 98.9% accuracy of elementary pose recognition by the combined accelerometer and video-based system, and 80% accuracy of complex outdoor activity recognition by the accelerometer-based wearable system.

Dental caries among Iranian elementary school children aged 6-12 years continue to rise. To estimate treatment needs and guide health initiatives, current epidemiologic data are required. Such data are currently unavailable for dental health. The purpose of this study was to assess caries experience, dental plaque, and associated factors in elementary school-aged children from Iran. In this cross-sectional study, 988 elementary school children aged 7-12 years were selected by multistage cluster sampling. Dental caries was studied using the WHO criteria, dental plaque was examined according to O'Leary index. Data on parental education and occupation, living district, dental pain within the past year, and tooth brushing habits under parental supervision were collected through interviews based on questionnaire. The data were analyzed with descriptive statistics and logistic and linear regression. The mean (SD) age of the elementary school children was 9.64 (1.73) years. The highest dmft was seen in elementary school children aged 7-8 years 6.53 (4.37) and the highest DMFT and dental plaque was in 12 year olds recorded as 1.17 (1.77) and 51.97 (25.86), respectively. The proportion of decayed teeth in 7 years old elementary school based on dmft index was 80.36%, moreover, the proportion in 12 years old elementary school was 40.17% based on the DMFT index. Age, gender, and dental pain within the past year were significantly associated with DMFT and dmft. The odds of developing dental caries (DMFT) was 1.70 times higher in girls than in boys (p < 0.001) and 1.72 times higher in the students that reported dental pain frequently than in those who did not (p = 0.005). The chance of developing dental caries (dmft) was 0.47 times lower in girls than boys (p < 0.001). Age was significantly correlated with dental plaque such that Plaque Index increased by 2.44 times per one year increase in age (p < 0.001). Results indicated that dental caries experience and plaque formation among elementary school children in Hamadan were high and they were influenced by their sociodemographic factors. The associations found can be used as a helpful guide for planning accurate preventive programs for elementary school children in this region.

Safdie, Margarita; Lévesque, Lucie; González-Casanova, Inés; Salvo, Deborah; Islas, Ana; Hernández-Cordero, Sonia; Bonvecchio, Anabelle; Rivera, Juan A

2013-01-01

This paper describes the rationale, design, and methods of a two-year randomized controlled trial conducted to evaluate the effectiveness of an environmental intervention in 27 elementary schools in Mexico City. There were two units of analysis, school level addressing changes in elementary public part-time schools, and individual-level addressing behavioral changes in students 9 to 11 years of age. Two intensities of an intervention program were implemented (basic and plus), each containing two intervention components: physical activity and nutrition, supported by a communication/education component. Evaluation of the intervention was carried out during the school cycles 2006-2007 and 2007-2008. Primary outcomes were overweight and obesity prevalence and fitness; environmental and behavioural measures were also examined. This is the first institutional multilevel, multifactorial project, consistent with the best practices available in current literature, carried out in Mexico to prevent childhood obesity in schools.

A full computation-relevant topological dynamics classification of elementary cellular automata.

PubMed

Schüle, Martin; Stoop, Ruedi

2012-12-01

Cellular automata are both computational and dynamical systems. We give a complete classification of the dynamic behaviour of elementary cellular automata (ECA) in terms of fundamental dynamic system notions such as sensitivity and chaoticity. The "complex" ECA emerge to be sensitive, but not chaotic and not eventually weakly periodic. Based on this classification, we conjecture that elementary cellular automata capable of carrying out complex computations, such as needed for Turing-universality, are at the "edge of chaos."

A transformation-aware perceptual image metric

NASA Astrophysics Data System (ADS)

Kellnhofer, Petr; Ritschel, Tobias; Myszkowski, Karol; Seidel, Hans-Peter

2015-03-01

Predicting human visual perception has several applications such as compression, rendering, editing and retargeting. Current approaches however, ignore the fact that the human visual system compensates for geometric transformations, e. g., we see that an image and a rotated copy are identical. Instead, they will report a large, false-positive difference. At the same time, if the transformations become too strong or too spatially incoherent, comparing two images indeed gets increasingly difficult. Between these two extrema, we propose a system to quantify the effect of transformations, not only on the perception of image differences, but also on saliency. To this end, we first fit local homographies to a given optical flow field and then convert this field into a field of elementary transformations such as translation, rotation, scaling, and perspective. We conduct a perceptual experiment quantifying the increase of difficulty when compensating for elementary transformations. Transformation entropy is proposed as a novel measure of complexity in a flow field. This representation is then used for applications, such as comparison of non-aligned images, where transformations cause threshold elevation, and detection of salient transformations.

Effects of School-Wide Positive Behavioral Interventions and Supports on Child Behavior Problems

PubMed Central

Waasdorp, Tracy E.; Leaf, Philip J.

2012-01-01

OBJECTIVE: School-Wide Positive Behavioral Interventions and Supports (SWPBIS) is a universal prevention strategy currently implemented in >16 000 schools across the United States. SWPBIS intends to reduce students’ behavior problems by altering staff behaviors and developing systems and supports to meet children’s behavioral needs. The current study reports intervention effects on child behaviors and adjustment from an effectiveness trial of SWPBIS. METHODS: The sample of 12 344 elementary school children was 52.9% male, 45.1% African American, and 46.1% Caucasian. Approximately 49% received free or reduced-priced meals, and 12.9% received special education services at baseline. The trial used a group randomized controlled effectiveness design implemented in 37 elementary schools. Multilevel analyses were conducted on teachers’ ratings of children’s behavior problems, concentration problems, social-emotional functioning, prosocial behavior, office discipline referrals, and suspensions at 5 time points over the course of 4 school years. RESULTS: The multilevel results indicated significant effects of SWPBIS on children’s behavior problems, concentration problems, social-emotional functioning, and prosocial behavior. Children in SWPBIS schools also were 33% less likely to receive an office discipline referral than those in the comparison schools. The effects tended to be strongest among children who were first exposed to SWPBIS in kindergarten. CONCLUSIONS: These findings provide support for the hypothesized reduction in behavior problems and improvements in prosocial behavior and effective emotion regulation after training in SWPBIS. The SWPBIS framework appears to be a promising approach for reducing problems and promoting adjustment among elementary school children. PMID:23071207

Committor of elementary reactions on multistate systems

NASA Astrophysics Data System (ADS)

Király, Péter; Kiss, Dóra Judit; Tóth, Gergely

2018-04-01

In our study, we extend the committor concept on multi-minima systems, where more than one reaction may proceed, but the feasible data evaluation needs the projection onto partial reactions. The elementary reaction committor and the corresponding probability density of the reactive trajectories are defined and calculated on a three-hole two-dimensional model system explored by single-particle Langevin dynamics. We propose a method to visualize more elementary reaction committor functions or probability densities of reactive trajectories on a single plot that helps to identify the most important reaction channels and the nonreactive domains simultaneously. We suggest a weighting for the energy-committor plots that correctly shows the limits of both the minimal energy path and the average energy concepts. The methods also performed well on the analysis of molecular dynamics trajectories of 2-chlorobutane, where an elementary reaction committor, the probability densities, the potential energy/committor, and the free-energy/committor curves are presented.

Non-Micropipe Dislocations in 4H-SiC Devices: Electrical Properties and Device Technology Implications

NASA Technical Reports Server (NTRS)

Neudeck, Philip G.; Huang, Wei; Dudley, Michael; Fazi, Christian

1998-01-01

It is well-known that SiC wafer quality deficiencies are delaying the realization of outstandingly superior 4H-SiC power electronics. While efforts to date have centered on eradicating micropipes (i.e., hollow core super-screw dislocations with Burgers vectors greater than or equal to 2c), 4H-SiC wafers and epilayers also contain elementary screw dislocations (i.e., Burgers vector = 1c with no hollow core) in densities on the order of thousands per sq cm, nearly 100-fold micropipe densities. While not nearly as detrimental to SiC device performance as micropipes, it has recently been demonstrated that elementary screw dislocations somewhat degrade the reverse leakage and breakdown properties of 4H-SiC p(+)n diodes. Diodes containing elementary screw dislocations exhibited a 5% to 35% reduction in breakdown voltage, higher pre-breakdown reverse leakage current, softer reverse breakdown I-V knee, and microplasmic breakdown current filaments that were non-catastrophic as measured under high series resistance biasing. This paper details continuing experimental and theoretical investigations into the electrical properties of 4H-SiC elementary screw dislocations. The nonuniform breakdown behavior of 4H-SiC p'n junctions containing elementary screw dislocations exhibits interesting physical parallels with nonuniform breakdown phenomena previously observed in other semiconductor materials. Based upon experimentally observed dislocation-assisted breakdown, a re-assessment of well-known physical models relating power device reliability to junction breakdown has been undertaken for 4H-SiC. The potential impact of these elementary screw dislocation defects on the performance and reliability of various 4H-SiC device technologies being developed for high-power applications will be discussed.

Analysis of an Attenuator Artifact in an Experimental Attack by Gunn-Allison-Abbott Against the Kirchhoff-Law-Johnson-Noise (KLJN) Secure Key Exchange System

NASA Astrophysics Data System (ADS)

Kish, Laszlo B.; Gingl, Zoltan; Mingesz, Robert; Vadai, Gergely; Smulko, Janusz; Granqvist, Claes-Göran

2015-12-01

A recent paper by Gunn-Allison-Abbott (GAA) [L. J. Gunn et al., Scientific Reports 4 (2014) 6461] argued that the Kirchhoff-law-Johnson-noise (KLJN) secure key exchange system could experience a severe information leak. Here we refute their results and demonstrate that GAA's arguments ensue from a serious design flaw in their system. Specifically, an attenuator broke the single Kirchhoff-loop into two coupled loops, which is an incorrect operation since the single loop is essential for the security in the KLJN system, and hence GAA's asserted information leak is trivial. Another consequence is that a fully defended KLJN system would not be able to function due to its built-in current-comparison defense against active (invasive) attacks. In this paper we crack GAA's scheme via an elementary current-comparison attack which yields negligible error probability for Eve even without averaging over the correlation time of the noise.

Computation of elementary modes: a unifying framework and the new binary approach

PubMed Central

Gagneur, Julien; Klamt, Steffen

2004-01-01

Background Metabolic pathway analysis has been recognized as a central approach to the structural analysis of metabolic networks. The concept of elementary (flux) modes provides a rigorous formalism to describe and assess pathways and has proven to be valuable for many applications. However, computing elementary modes is a hard computational task. In recent years we assisted in a multiplication of algorithms dedicated to it. We require a summarizing point of view and a continued improvement of the current methods. Results We show that computing the set of elementary modes is equivalent to computing the set of extreme rays of a convex cone. This standard mathematical representation provides a unified framework that encompasses the most prominent algorithmic methods that compute elementary modes and allows a clear comparison between them. Taking lessons from this benchmark, we here introduce a new method, the binary approach, which computes the elementary modes as binary patterns of participating reactions from which the respective stoichiometric coefficients can be computed in a post-processing step. We implemented the binary approach in FluxAnalyzer 5.1, a software that is free for academics. The binary approach decreases the memory demand up to 96% without loss of speed giving the most efficient method available for computing elementary modes to date. Conclusions The equivalence between elementary modes and extreme ray computations offers opportunities for employing tools from polyhedral computation for metabolic pathway analysis. The new binary approach introduced herein was derived from this general theoretical framework and facilitates the computation of elementary modes in considerably larger networks. PMID:15527509

Personal goals as predictors of intended classroom goals: comparing elementary and secondary school pre-service teachers.

PubMed

Daniels, Lia M; Frenzel, Anne C; Stupnisky, Robert H; Stewart, Tara L; Perry, Raymond P

2013-09-01

The literature documents fewer classroom mastery goal structures in secondary school compared to elementary. However, little is known about how personal achievement goals may influence classroom goal structures. This is especially true at the level of pre-service teachers. Our objective was to investigate if pre-service teachers' personal goals predicted their intended classroom goal structures. Participants were 125 elementary and 175 secondary school pre-service teachers from two Western Canadian universities. Structural equation modelling was used to examine if the structural relationships and latent means of personal and intended classroom goal structures differed for elementary and secondary school pre-service teachers. The results revealed that personal goals predicted the goal structures that pre-service teachers intended to establish; however, the relationships and means differed between elementary and secondary school pre-service teachers. Specifically, personal mastery-approach goals positively predicted classroom mastery goals much more strongly at the elementary than the secondary level. Furthermore, elementary pre-service teachers had significantly higher latent mean scores on personal mastery-approach goals than their secondary counterparts. It seems possible that the currently documented differences between classroom goal structures noted for elementary compared to secondary school may be based on the personal goals endorsed as pre-service teachers. The results are further discussed in terms of alignment with research on practising teachers' personal and classroom goals and implications for teacher education. © 2012 The British Psychological Society.

Magnetic field generated by lightning protection system

NASA Astrophysics Data System (ADS)

Geri, A.; Veca, G. M.

1988-04-01

A lightning protection system for today's civil buildings must be electromagnetically compatible with the electronic equipment present in the building. This paper highlights a mathematic model which analyzes the electromagnetic effects in the environment in which the lightning protection system is. This model is developed by means of finite elements of an electrical circuit where each element is represented by a double pole circuit according to the trapezoidal algorithm developed using the finite difference method. It is thus possible to analyze the electromagnetic phenomena associated with the transient effects created by the lightning stroke even for a high-intensity current. Referring to an elementary system comprised of an air terminal, a down conductor, and a ground terminal, numerical results are here laid out.

Engineering Professional Development: Elementary Teachers' Self-efficacy and Sources of Self-efficacy

NASA Astrophysics Data System (ADS)

Webb, Donna Louise

Currently, STEM (science, technology, engineering, and mathematics) is a popular buzz word in P-12 education as it represents a means to advance American competitiveness in the global economy. Proponents of the engineering component of STEM advocate additional benefits in teaching engineering, such as its capacity to engage students in collaboration, and to apply critical thinking, systems thinking, negotiation, and communication skills to solve real-life contextual problems. Establishing a strong foundation of engineering knowledge at a young age will provide students with internal motivation as it taps into their curiosity toward how things work, and it also prepares them for secondary science courses. Successful STEM education is often constrained by elementary teachers' low perception of self-efficacy to teach science and engineering. Elementary teachers with low self-efficacy in science are more likely to spend less instructional time teaching science, which suggests that teachers with little to no training in engineering might avoid teaching this topic. Therefore, the purpose of this study was twofold: (a) to examine the effects of engineering professional development on elementary (K-6) teachers' content and pedagogical content knowledge (PCK) and perceptions of self-efficacy to teach engineering, and (b) to identify and explain sources influencing self-efficacy. Professional development was conducted in a metropolitan area in the Pacific Northwest. Results revealed that after the engineering professional development, teachers experienced statistically significant gains in content, PCK, and self-efficacy to teach engineering. Increases in self-efficacy were mainly attributed to mastery experiences and cultivation of a growth mindset by embracing the engineering design process.

2014-01-01

In this study, a model that is capable of evaluating the environmental benefits of a new elementary school facility was developed. The model is composed of three steps: (i) retrieval of elementary school facilities having similar characteristics as the new elementary school facility using case-based reasoning; (ii) creation of energy consumption and material data for the benchmark elementary school facility using the retrieved similar elementary school facilities; and (iii) evaluation of the environmental benefits of the new elementary school facility by assessing and comparing the environmental impact of the new and created benchmark elementary school facility using life cycle assessment. The developed model can present the environmental benefits of a new elementary school facility in terms of monetary values using Environmental Priority Strategy 2000, a damage-oriented life cycle impact assessment method. The developed model can be used for the following: (i) as criteria for a green-building rating system; (ii) as criteria for setting the support plan and size, such as the government's incentives for promoting green-building projects; and (iii) as criteria for determining the feasibility of green building projects in key business sectors.

Bringing the Science of Climate Change to Elementary Students with new Classroom Activities from Elementary GLOBE

NASA Astrophysics Data System (ADS)

Gardiner, L. S.; Hatheway, B.; Taylor, J.; Chambers, L. H.; Stanitski, D.

2016-12-01

To address the dearth of climate education resources at the elementary level, we have developed a new module of Elementary GLOBE to showcase the science of climate change for young learners. Elementary GLOBE builds K-4 student understanding of the science concepts and the practices of science research. At the heart of each Elementary GLOBE module is a fiction storybook, describing how three kids investigate a science question. Accompanying classroom activities allow students to explore the science concepts in the book in more depth and in a context appropriate for young learners. The book for the Elementary GLOBE climate module, "What in the World Is Happening to Our Climate?," is the account of an adventure to explore climate change, how it is affecting melting glacial ice and sea level rise, and how climate change is a problem that can be solved. Three hands-on activities, which will be presented at this session, allow students to explore the topics in greater depth including differences between weather and climate, how sea level rise affects coastal areas, and how they can shrink their carbon footprint to help address recent climate change. Each activity includes instructions for teachers, background information, and activity sheets for students, and is aligned to the Next Generation Science Standards and Common Core Math and Language Arts Standards. The storybook and activities were field tested in classrooms and reviewed by climate and Earth system scientists as well as elementary education and climate education specialists and educators to ensure scientific accuracy and clear explanations, and that the resources are age appropriate and reflect the needs of the climate education community. Other Elementary GLOBE modules include the science of seasonal change, water, soil, clouds, aerosols, and Earth as a system. All Elementary GLOBE educational resources are freely available online (www.globe.gov/elementaryglobe).

Empirical justification of the elementary model of money circulation

Schinckus, Christophe; Altukhov, Yurii A.; Pokrovskii, Vladimir N.

2018-03-01

This paper proposes an elementary model describing the money circulation for a system, composed by a production system, the government, a central bank, commercial banks and their customers. A set of equations for the system determines the main features of interaction between the production and the money circulation. It is shown, that the money system can evolve independently of the evolution of production. The model can be applied to any national economy but we will illustrate our claim in the context of the Russian monetary system.

Microscopic origin of gating current fluctuations in a potassium channel voltage sensor.

2012-06-06

Voltage-dependent ion channels open and close in response to changes in membrane electrical potential due to the motion of their voltage-sensing domains (VSDs). VSD charge displacements within the membrane electric field are observed in electrophysiology experiments as gating currents preceding ionic conduction. The elementary charge motions that give rise to the gating current cannot be observed directly, but appear as discrete current pulses that generate fluctuations in gating current measurements. Here we report direct observation of gating-charge displacements in an atomistic molecular dynamics simulation of the isolated VSD from the KvAP channel in a hydrated lipid bilayer on the timescale (10-μs) expected for elementary gating charge transitions. The results reveal that gating-charge displacements are associated with the water-catalyzed rearrangement of salt bridges between the S4 arginines and a set of conserved acidic side chains on the S1-S3 transmembrane segments in the hydrated interior of the VSD.

Improved adaptive splitting and selection: the hybrid training method of a classifier based on a feature space partitioning.

PubMed

Jackowski, Konrad; Krawczyk, Bartosz; Woźniak, Michał

2014-05-01

Currently, methods of combined classification are the focus of intense research. A properly designed group of combined classifiers exploiting knowledge gathered in a pool of elementary classifiers can successfully outperform a single classifier. There are two essential issues to consider when creating combined classifiers: how to establish the most comprehensive pool and how to design a fusion model that allows for taking full advantage of the collected knowledge. In this work, we address the issues and propose an AdaSS+, training algorithm dedicated for the compound classifier system that effectively exploits local specialization of the elementary classifiers. An effective training procedure consists of two phases. The first phase detects the classifier competencies and adjusts the respective fusion parameters. The second phase boosts classification accuracy by elevating the degree of local specialization. The quality of the proposed algorithms are evaluated on the basis of a wide range of computer experiments that show that AdaSS+ can outperform the original method and several reference classifiers.

Implementation of Teacher Consultation and Coaching in Urban Schools: A Mixed Method Study

Cappella, Elise; Jackson, Daisy R.; Kim, Ha Yeon; Bilal, Caroline; Holland, Sibyl; Atkins, Marc S.

2015-01-01

Guided by implementation science scholarship and school mental health research, the current study uses qualitative and quantitative data to illuminate the barriers, opportunities, and processes underlying the implementation of a teacher consultation and coaching model (BRIDGE) in urban elementary schools. Data come from five public elementary schools, 12 school mental health staff (BRIDGE consultants), and 18 teachers participating in a classroom-randomized trial of BRIDGE. Findings from directed content analysis of teacher focus group and interview data suggest that aspects of the BRIDGE intervention model, school organization and classroom contexts, and teachers/consultants and their relationship were relevant as implementation facilitators or barriers. In addition, case study analysis of intervention materials and fidelity tools from classrooms with moderate-to-high dosage and adherence suggest variation in consultation and coaching by initial level of observed classroom need. Results illuminate the need for implementation research to extend beyond simple indicators of fidelity to the multiple systems and variation in processes at play across levels of the implementation context.

2013-12-01

This study explores ways southeast Minnesota schools currently address asthma problems, identifies areas for improvement, and assesses the potential value of asthma action plans (AAPs) in schools. Focus groups were used to query stakeholder groups on asthma care in schools. Groups were held separately for elementary school personnel, parents of elementary school children with asthma, and health professionals (N = 103). Transcripts were analyzed by hand and by using NVivo 9 software. Overall 103 stakeholders participated in focus groups. Major themes were (1) Communication; no uniform way of exchanging information between schools and health professionals. (2) Asthma Control Continuum; students require individualized instructions and information related to their asthma care. (3) Policy/Protocol; school staff roles and rules vary and are unclear. (4) Self-Reliance; older children self-manage their asthma and are unknown until they need emergent support. Solution recommended included AAPs used systematically with a method to communicate back from schools to physicians and parents. The AAP may solve several of the school's concerns regarding their ability to provide asthma support in school. However, the AAP must reach the school, and that is currently not happening. In addition, schools would like tools and systems to assess asthma control and share information back with parents and physicians. © 2013, American School Health Association.

A narrative study of novice elementary teachers' perceptions of science instruction

NASA Astrophysics Data System (ADS)

Harrell, Roberta

It is hoped that, once implemented, the Next Generation Science Standards (NGSS) will engage students more deeply in science learning and build science knowledge sequentially beginning in Kindergarten (NRC, 2013). Early instruction is encouraged but must be delivered by qualified elementary teachers who have both the science content knowledge and the necessary instructional skills to teach science effectively to young children (Ejiwale, 2012, Spencer, Vogel, 2009, Walker, 2011). The purpose of this research study is to gain insight into novice elementary teachers' perceptions of science instruction. This research suggests that infusion of constructivist teaching in the elementary classroom is beneficial to the teacher's instruction of science concepts to elementary students. Constructivism is theory that learning is centered on the learner constructing new ideas or concepts built upon their current/past knowledge (Bruner, 1966). Based on this theory, it is recommended that the instructor should try to encourage students to discover principles independently; essentially the instructor presents the problem and lets students go (Good & Brophy, 2004). Discovery learning, hands-on, experimental, collaborative, and project-based learning are all approaches that use constructivist principles. The NGSS are based on constructivist principles. This narrative study provides insight into novice elementary teachers' perceptions of science instruction considered through the lens of Constructivist Theory (Bruner, 1960).

2017-02-01

Currently there is a lack in fundamental understanding of disease progression of most neurodegenerative diseases, and, therefore, treatments and preventative measures are limited. Consequently, there is a great need for adaptable, yet robust model systems to both investigate elementary disease mechanisms and discover effective therapeutics. We have generated a Tol2 Gateway-compatible toolbox to study neurodegenerative disorders in zebrafish, which includes promoters for astrocytes, microglia and motor neurons, multiple fluorophores, and compatibility for the introduction of genes of interest or disease-linked genes. This toolbox will advance the rapid and flexible generation of zebrafish models to discover the biology of the nervous system and the disease processes that lead to neurodegeneration.

Determining the value of the fine-structure constant from a current balance: Getting acquainted with some upcoming changes to the SI

NASA Astrophysics Data System (ADS)

Davis, Richard S.

2017-05-01

The revised International System of Units (SI), expected to be approved late in 2018, has implications for physics pedagogy. The ampere definition, which dates from 1948, will be replaced by a definition that fixes the numerical value of the elementary charge e in coulombs. The kilogram definition, which dates from 1889, will be replaced by a definition that fixes the numerical value of the Planck constant h in joule seconds. Existing SI equations will be completely unaffected. However, there will be a largely negligible, but nevertheless necessary, change to published numerical factors relating SI electrical units to their corresponding units in the Gaussian and other CGS systems of units. The implications of the revised SI for electrical metrology are neatly illustrated by considering the interpretation of results obtained from a current balance in the present SI and in the revised SI.

The effect of pore-scale geometry and wettability on two-phase relative permeabilities within elementary cells

NASA Astrophysics Data System (ADS)

Bianchi Janetti, Emanuela; Riva, Monica; Guadagnini, Alberto

2017-04-01

We study the relative role of the complex pore space geometry and wettability of the solid matrix on the quantification of relative permeabilities characterizing steady state immiscible two-phase flow in porous media. We do so by considering elementary cells, which are typically employed in upscaling frameworks based on, e.g., homogenization or volume averaging. In this context one typically relies on the solution of pore-scale physics at a scale which is much smaller than that of an investigated porous system. Pressure-driven two-phase flow following simultaneous co-current injection of water and oil is numerically solved for a suite of regular and stochastically generated two-dimensional explicit elementary cells with fixed porosity and sharing main topological/morphological features. We show that relative permeabilities of the randomly generated elementary cells are significantly influenced by the formation of preferential percolation paths (principal pathways), giving rise to a strongly nonuniform distribution of fluid fluxes. These pathways are a result of the spatially variable resistance that the random pore structures exert on the fluid. The overall effect on relative permeabilities of the diverse organization of principal pathways, as driven by a given random realization at the scale of the unit cell, is significantly larger than that of the wettability of the host rock. In contrast to what can be observed for the random cells analyzed, relative permeabilities of regular cells display a clear trend with contact angle at the investigated scale. Our findings suggest the need to perform systematic upscaling studies in a stochastic context, to propagate the effects of uncertain pore space geometries to a probabilistic description of relative permeability curves at the continuum scale.

A network view on psychiatric disorders: network clusters of symptoms as elementary syndromes of psychopathology.

PubMed

Goekoop, Rutger; Goekoop, Jaap G

2014-01-01

The vast number of psychopathological syndromes that can be observed in clinical practice can be described in terms of a limited number of elementary syndromes that are differentially expressed. Previous attempts to identify elementary syndromes have shown limitations that have slowed progress in the taxonomy of psychiatric disorders. To examine the ability of network community detection (NCD) to identify elementary syndromes of psychopathology and move beyond the limitations of current classification methods in psychiatry. 192 patients with unselected mental disorders were tested on the Comprehensive Psychopathological Rating Scale (CPRS). Principal component analysis (PCA) was performed on the bootstrapped correlation matrix of symptom scores to extract the principal component structure (PCS). An undirected and weighted network graph was constructed from the same matrix. Network community structure (NCS) was optimized using a previously published technique. In the optimal network structure, network clusters showed a 89% match with principal components of psychopathology. Some 6 network clusters were found, including "Depression", "Mania", "Anxiety", "Psychosis", "Retardation", and "Behavioral Disorganization". Network metrics were used to quantify the continuities between the elementary syndromes. We present the first comprehensive network graph of psychopathology that is free from the biases of previous classifications: a 'Psychopathology Web'. Clusters within this network represent elementary syndromes that are connected via a limited number of bridge symptoms. Many problems of previous classifications can be overcome by using a network approach to psychopathology.

Development and Implementation of an Integrated Science Course for Elementary Eduation Majors

1997-02-01

Currently the scientific community is trying to increase the general populationapos;s knowledge of science. These efforts stem from the fact that the citizenry needs a better understanding of scientific knowledge to make informed decisions on many issues of current concern. The problem of scientific illiteracy begins in grade school and can be traced to inadequate exposure to science and scientific thinking during the preparation of K - 8 teachers. Typically preservice elementary teachers are required to take only one or two disconnected science courses to obtain their teaching certificates. Also, introductory science courses are often large and impersonal, with the result that while students pass the courses, they may learn very little and retain even less.

The relationship between heavy metal and rap music and adolescent turmoil: real or artifact?

PubMed

Took, K J; Weiss, D S

1994-01-01

Adolescents and their parents were surveyed to investigate the association between heavy metal and rap music and adolescent psychosocial turmoil. Subjects were asked about current and past psychosocial functioning, as well as their music preferences. Adolescents who preferred heavy metal and rap music were compared with those who preferred other types of music. Results indicated that adolescents who preferred heavy metal and rap had a higher incidence of below-average school grades, school behavior problems, sexual activity, drug and alcohol use, and arrests. However, when gender was controlled, only below-average current and elementary school grades and a history of counseling in elementary school for school problems remained significant. Implications of these findings are discussed.

Student Mastery of the Sun-Earth-Moon System in a Flipped Classroom of Pre-service Elementary Education Students

NASA Astrophysics Data System (ADS)

Larsen, Kristine

2014-01-01

One of the current trends in pedagogy at all levels(K-college) is the so-called ‘flipped classroom’, in which students prepare for a class meeting through self-study of the material. It is based on a rejection of the classic model of the faculty member as the ‘sage on the stage’ instead, responsibility for learning shifts to the individual student. The faculty member takes on the role of learning facilitator or mentor, and focuses the students’ learning by crafting and administering timely formative assessments (in multiple formats and applied multiple times) that aid both students and the faculty member in tracking the students’ mastery of the learning outcomes. In a flipped, freshman-only, section of SCI 111 Elementary Earth-Physical Sciences (a required introductory science course for pre-service elementary school teachers) the students learned through a combination of individual and group hands-on in-class activities, technology (including PowerPoint presentations and short videos viewed prior to attending class), in-class worksheets, and in-class discussions. Students self-differentiated in how they interacted with the available teaching materials, deciding which activities to spend the most time on based on their individual needs (based on an online quiz taken the night before the class period, and their personal self-confidence with the material). Available in-class activities and worksheets were developed by the faculty member based on student scores on the online quiz as well as personal messages submitted through the course management system the night before the class meeting. While this placed a significant burden on the faculty member in terms of course preparation, it allowed for just-in-time teaching to take place. This poster describes the results of student mastery of content centered on the sun-earth-moon system (specifically seasons, moon phases, and eclipses) as compared to traditional classroom sections.

A gradient system solution to Potts mean field equations and its electronic implementation.

PubMed

Urahama, K; Ueno, S

1993-03-01

A gradient system solution method is presented for solving Potts mean field equations for combinatorial optimization problems subject to winner-take-all constraints. In the proposed solution method the optimum solution is searched by using gradient descent differential equations whose trajectory is confined within the feasible solution space of optimization problems. This gradient system is proven theoretically to always produce a legal local optimum solution of combinatorial optimization problems. An elementary analog electronic circuit implementing the presented method is designed on the basis of current-mode subthreshold MOS technologies. The core constituent of the circuit is the winner-take-all circuit developed by Lazzaro et al. Correct functioning of the presented circuit is exemplified with simulations of the circuits implementing the scheme for solving the shortest path problems.

A Problem Based Learning Project Analyzing Rubrics Used to Evaluate Elementary STEM Immersion Programs

NASA Astrophysics Data System (ADS)

Pearson, Roxanne N.

In 2010, the President's Council of Advisors on Science and Technology recommended that eight hundred new STEM focused elementary and middle schools be established. Unfortunately, districts may be slow to implement STEM at the elementary level because they do not understand how to do so effectively (Zimny, 2017). School administrators need a framework for decision-making and supervisory feedback related to the process of managing these programs (Zimny, 2017). To support administrators in implementing elementary STEM immersion programs, this project explored three questions: What criteria are common among existing STEM immersion program rubrics? What criteria should be included in a comprehensive rubric for managing elementary STEM immersion programs at the district level? What do district documents show about how elementary STEM immersion programs develop, implement, and evaluate those programs? The team developed a comprehensive STEM program review instrument including criteria for effective elementary STEM curriculum and the professional development and administrative support necessary to implement such curriculum. These criteria were organized into three stages, including the planning and development of elementary STEM immersion programs, the implementation of these programs, and the evaluation of these programs after they had been implemented for a significant period of time. The team synthesized best practice indicators relevant to elementary STEM programs from existing K-12 guides, then validated those indicators against current best practice research and feedback from STEM education experts. District documents from seven elementary STEM immersion programs in Missouri and Colorado were examined using the team's rubric. Scores were higher in the areas of program planning, content alignment, and ongoing refinement of curriculum, and lower in the areas of professional development for professional skills and STEM-specific pedagogy, two-way communication with stakeholders, and data collection for program refinement. Scores were lowest for those schools with inadequate documentation of their program management processes. The team recommended districts institute a more rigorous documentation process for managing innovative programs such as STEM immersion. Communication plans should include procedures for two-way communication with all stakeholders. Data collection and refinement efforts should increase, as should professional development opportunities related to professional skills and STEM-specific pedagogy; this should include administrators.

Transformation-aware perceptual image metric

Kellnhofer, Petr; Ritschel, Tobias; Myszkowski, Karol; Seidel, Hans-Peter

2016-09-01

Predicting human visual perception has several applications such as compression, rendering, editing, and retargeting. Current approaches, however, ignore the fact that the human visual system compensates for geometric transformations, e.g., we see that an image and a rotated copy are identical. Instead, they will report a large, false-positive difference. At the same time, if the transformations become too strong or too spatially incoherent, comparing two images gets increasingly difficult. Between these two extrema, we propose a system to quantify the effect of transformations, not only on the perception of image differences but also on saliency and motion parallax. To this end, we first fit local homographies to a given optical flow field, and then convert this field into a field of elementary transformations, such as translation, rotation, scaling, and perspective. We conduct a perceptual experiment quantifying the increase of difficulty when compensating for elementary transformations. Transformation entropy is proposed as a measure of complexity in a flow field. This representation is then used for applications, such as comparison of nonaligned images, where transformations cause threshold elevation, detection of salient transformations, and a model of perceived motion parallax. Applications of our approach are a perceptual level-of-detail for real-time rendering and viewpoint selection based on perceived motion parallax.

Interesting physics problems that can be used as examples in introductory physics courses relating to the waste of thermal energy can be found in the mechanical systems of campus buildings. The design of these wasteful systems may represent the ``state of the art'' as it existed just a few years ago, so such examples are probably abundant. Our Student Recreation Center was opened in 1973. It has an ice skating rink with the associated large refrigeration system. Simple calculations using elementary thermodynamics applied to this system show that the heat rejected by the system is roughly a quarter of a megawatt, which is approximately the average thermal power needed to heat water for the showers in the building. An outcome of this student project is the recommendation that the rejected heat be used to heat (or preheat) the shower water at an estimated annual saving of 40 000 in current energy costs.

Status of teaching elementary science for English learners in science, mathematics and technology centered magnet schools

NASA Astrophysics Data System (ADS)

Han, Alyson Kim

According to the California Commission on Teacher Credentialing (2001), one in three students speaks a language other than English. Additionally, the Commission stated that a student is considered to be an English learner if the second language acquisition is English. In California more than 1.4 million English learners enter school speaking a variety of languages, and this number continues to rise. There is an imminent need to promote instructional strategies that support this group of diverse learners. Although this was not a California study, the results derived from the nationwide participants' responses provided a congruent assessment of the basic need to provide effective science teaching strategies to all English learners. The purpose of this study was to examine the status of elementary science teaching practices used with English learners in kindergarten through fifth grade in public mathematics, science, and technology-centered elementary magnet schools throughout the country. This descriptive research was designed to provide current information and to identify trends in the areas of curriculum and instruction for English learners in science themed magnet schools. This report described the status of elementary (grades K-5) school science instruction for English learners based on the responses of 116 elementary school teachers: 59 grade K-2, and 57 grade 3-5 teachers. Current research-based approaches support incorporating self-directed learning strategy, expository teaching strategy, active listening strategies, questioning strategies, wait time strategy, small group strategy, peer tutoring strategy, large group learning strategy, demonstrations strategy, formal debates strategy, review sessions strategy, mediated conversation strategy, cooperative learning strategy, and theme-based instruction into the curriculum to assist English learners in science education. Science Technology Society (STS) strategy, problem-based learning strategy, discovery learning strategy, constructivist learning strategy, learning cycle strategy, SCALE technique strategy, conceptual change strategy, inquiry-based strategy, cognitive academic language learning approach (CALLA) strategy, and learning from text strategy provide effective science teaching instruction to English learners. These science instructional strategies assist elementary science teachers by providing additional support to make science instruction more comprehensible for English learners.

Teaching Systems Thinking in the Context of the Water Cycle

Lee, Tammy D.; Gail Jones, M.; Chesnutt, Katherine

2017-06-01

Complex systems affect every part of our lives from the ecosystems that we inhabit and share with other living organisms to the systems that supply our water (i.e., water cycle). Evaluating events, entities, problems, and systems from multiple perspectives is known as a systems thinking approach. New curriculum standards have made explicit the call for teaching with a systems thinking approach in our science classrooms. However, little is known about how elementary in-service or pre-service teachers understand complex systems especially in terms of systems thinking. This mixed methods study investigated 67 elementary in-service teachers' and 69 pre-service teachers' knowledge of a complex system (e.g., water cycle) and their knowledge of systems thinking. Semi-structured interviews were conducted with a sub-sample of participants. Quantitative and qualitative analyses of content assessment data and questionnaires were conducted. Results from this study showed elementary in-service and pre-service teachers applied different levels of systems thinking from novice to intermediate. Common barriers to complete systems thinking were identified with both in-service and pre-service teachers and included identifying components and processes, recognizing multiple interactions and relationships between subsystems and hidden dimensions, and difficulty understanding the human impact on the water cycle system.

A Network View on Psychiatric Disorders: Network Clusters of Symptoms as Elementary Syndromes of Psychopathology

PubMed Central

Goekoop, Rutger; Goekoop, Jaap G.

2014-01-01

Introduction The vast number of psychopathological syndromes that can be observed in clinical practice can be described in terms of a limited number of elementary syndromes that are differentially expressed. Previous attempts to identify elementary syndromes have shown limitations that have slowed progress in the taxonomy of psychiatric disorders. Aim To examine the ability of network community detection (NCD) to identify elementary syndromes of psychopathology and move beyond the limitations of current classification methods in psychiatry. Methods 192 patients with unselected mental disorders were tested on the Comprehensive Psychopathological Rating Scale (CPRS). Principal component analysis (PCA) was performed on the bootstrapped correlation matrix of symptom scores to extract the principal component structure (PCS). An undirected and weighted network graph was constructed from the same matrix. Network community structure (NCS) was optimized using a previously published technique. Results In the optimal network structure, network clusters showed a 89% match with principal components of psychopathology. Some 6 network clusters were found, including "DEPRESSION", "MANIA", “ANXIETY”, "PSYCHOSIS", "RETARDATION", and "BEHAVIORAL DISORGANIZATION". Network metrics were used to quantify the continuities between the elementary syndromes. Conclusion We present the first comprehensive network graph of psychopathology that is free from the biases of previous classifications: a ‘Psychopathology Web’. Clusters within this network represent elementary syndromes that are connected via a limited number of bridge symptoms. Many problems of previous classifications can be overcome by using a network approach to psychopathology. PMID:25427156

A pedagogical example of second-order arithmetic sequences applied to the construction of computer passwords by upper elementary grade students

NASA Astrophysics Data System (ADS)

Coggins, Porter E.

2015-04-01

The purpose of this paper is (1) to present how general education elementary school age students constructed computer passwords using digital root sums and second-order arithmetic sequences, (2) argue that computer password construction can be used as an engaging introduction to generate interest in elementary school students to study mathematics related to computer science, and (3) share additional mathematical ideas accessible to elementary school students that can be used to create computer passwords. This paper serves to fill a current gap in the literature regarding the integration of mathematical content accessible to upper elementary school students and aspects of computer science in general, and computer password construction in particular. In addition, the protocols presented here can serve as a hook to generate further interest in mathematics and computer science. Students learned to create a random-looking computer password by using biometric measurements of their shoe size, height, and age in months and to create a second-order arithmetic sequence, then converted the resulting numbers into characters that become their computer passwords. This password protocol can be used to introduce students to good computer password habits that can serve a foundation for a life-long awareness of data security. A refinement of the password protocol is also presented.

Teaching Healthy Eating to Elementary School Students: A Scoping Review of Nutrition Education Resources.

PubMed

Peralta, Louisa R; Dudley, Dean A; Cotton, Wayne G

2016-05-01

School-based programs represent an ideal setting to enhance healthy eating, as most children attend school regularly and consume at least one meal and a number of snacks at school each day. However, current research reports that elementary school teachers often display low levels of nutritional knowledge, self-efficacy, and skills to effectively deliver nutrition education. The purpose of this review was to understand the availability and quality of resources that are accessible for elementary school teachers to use to support curriculum delivery or nutrition education programs. The review included 32 resources from 4 countries in the final analysis from 1989 to 2014. The 32 resources exhibited 8 dominant teaching strategies: curriculum approaches; cross-curricular approaches; parental involvement; experiential learning approaches; contingent reinforcement approaches; literary abstraction approaches; games-based approaches; and web-based approaches. The resources were accessible to elementary school teachers, with all the resources embedding curriculum approaches, and most of the resources embedding parental involvement strategies. Resources were less likely to embed cross-curricular and experiential learning approaches, as well as contingent reinforcement approaches, despite recent research suggesting that the most effective evidence-based strategies for improving healthy eating in elementary school children are cross-curricular and experiential learning approaches. © 2016, American School Health Association.

Pey, Jon; Rubio, Angel; Theodoropoulos, Constantinos; Cascante, Marta; Planes, Francisco J

2012-07-01

Constraints-based modeling is an emergent area in Systems Biology that includes an increasing set of methods for the analysis of metabolic networks. In order to refine its predictions, the development of novel methods integrating high-throughput experimental data is currently a key challenge in the field. In this paper, we present a novel set of constraints that integrate tracer-based metabolomics data from Isotope Labeling Experiments and metabolic fluxes in a linear fashion. These constraints are based on Elementary Carbon Modes (ECMs), a recently developed concept that generalizes Elementary Flux Modes at the carbon level. To illustrate the effect of our ECMs-based constraints, a Flux Variability Analysis approach was applied to a previously published metabolic network involving the main pathways in the metabolism of glucose. The addition of our ECMs-based constraints substantially reduced the under-determination resulting from a standard application of Flux Variability Analysis, which shows a clear progress over the state of the art. In addition, our approach is adjusted to deal with combinatorial explosion of ECMs in genome-scale metabolic networks. This extension was applied to infer the maximum biosynthetic capacity of non-essential amino acids in human metabolism. Finally, as linearity is the hallmark of our approach, its importance is discussed at a methodological, computational and theoretical level and illustrated with a practical application in the field of Isotope Labeling Experiments.

Bounded Parametric Model Checking for Elementary Net Systems

NASA Astrophysics Data System (ADS)

Knapik, Michał; Szreter, Maciej; Penczek, Wojciech

Bounded Model Checking (BMC) is an efficient verification method for reactive systems. BMC has been applied so far to verification of properties expressed in (timed) modal logics, but never to their parametric extensions. In this paper we show, for the first time that BMC can be extended to PRTECTL - a parametric extension of the existential version of CTL. To this aim we define a bounded semantics and a translation from PRTECTL to SAT. The implementation of the algorithm for Elementary Net Systems is presented, together with some experimental results.

Current's Fluctuations through Molecular Wires Composed of Thiophene Rings.

PubMed

Ojeda Silva, Judith Helena; Cortés Peñaranda, Juan Camilo; Gómez Castaño, Jovanny A; Duque, Carlos Alberto

2018-04-11

We study theoretically the electronic transport and quantum fluctuations in single-molecule systems using thiophene rings as integrated elementary functions, as well as the dependence of these properties with the increase of the coupled rings, i.e., as a quantum wire. In order to analyze the current flow through these molecular systems, the thiophene rings are considered to be connected to metal contacts, which, in general terms, will be related to the application of voltages (bias voltages or gate voltages) to generate non-equilibrium behavior between the contacts. Due to the nonlinear behavior that is generated when said voltages are applied, it is possible to observe quantum fluctuations in the transport properties of these molecular wires. For the calculation of the transport properties, we applied a tight-binding approach using the Landauer-Büttiker formalism and the Fischer-Lee relationship, by means of a semi-analytic Green's function method within a real-space renormalization (decimation procedure). Our results showed an excellent agreement with results using a tight-binding model with a minimal number of parameters reported so far for these molecular systems.

Avoiding the Enumeration of Infeasible Elementary Flux Modes by Including Transcriptional Regulatory Rules in the Enumeration Process Saves Computational Costs

PubMed Central

Jungreuthmayer, Christian; Ruckerbauer, David E.; Gerstl, Matthias P.; Hanscho, Michael; Zanghellini, Jürgen

2015-01-01

Despite the significant progress made in recent years, the computation of the complete set of elementary flux modes of large or even genome-scale metabolic networks is still impossible. We introduce a novel approach to speed up the calculation of elementary flux modes by including transcriptional regulatory information into the analysis of metabolic networks. Taking into account gene regulation dramatically reduces the solution space and allows the presented algorithm to constantly eliminate biologically infeasible modes at an early stage of the computation procedure. Thereby, computational costs, such as runtime, memory usage, and disk space, are extremely reduced. Moreover, we show that the application of transcriptional rules identifies non-trivial system-wide effects on metabolism. Using the presented algorithm pushes the size of metabolic networks that can be studied by elementary flux modes to new and much higher limits without the loss of predictive quality. This makes unbiased, system-wide predictions in large scale metabolic networks possible without resorting to any optimization principle. PMID:26091045

Building blocks of topological quantum chemistry: Elementary band representations

Cano, Jennifer; Bradlyn, Barry; Wang, Zhijun; Elcoro, L.; Vergniory, M. G.; Felser, C.; Aroyo, M. I.; Bernevig, B. Andrei

2018-01-01

The link between chemical orbitals described by local degrees of freedom and band theory, which is defined in momentum space, was proposed by Zak several decades ago for spinless systems with and without time reversal in his theory of "elementary" band representations. In a recent paper [Bradlyn et al., Nature (London) 547, 298 (2017), 10.1038/nature23268] we introduced the generalization of this theory to the experimentally relevant situation of spin-orbit coupled systems with time-reversal symmetry and proved that all bands that do not transform as band representations are topological. Here we give the full details of this construction. We prove that elementary band representations are either connected as bands in the Brillouin zone and are described by localized Wannier orbitals respecting the symmetries of the lattice (including time reversal when applicable), or, if disconnected, describe topological insulators. We then show how to generate a band representation from a particular Wyckoff position and determine which Wyckoff positions generate elementary band representations for all space groups. This theory applies to spinful and spinless systems, in all dimensions, with and without time reversal. We introduce a homotopic notion of equivalence and show that it results in a finer classification of topological phases than approaches based only on the symmetry of wave functions at special points in the Brillouin zone. Utilizing a mapping of the band connectivity into a graph theory problem, we show in companion papers which Wyckoff positions can generate disconnected elementary band representations, furnishing a natural avenue for a systematic materials search.

Life histories of female elementary teachers and their science/teacher role construction

NASA Astrophysics Data System (ADS)

Ramseur, Aletha Johnson

The research conducted in this study focuses on life histories of female elementary teachers and their science/teacher role construction. Identity theorists argue that the self consists of a collection of identities founded on occupying a particular role. Who we are depends on the roles we occupy. These roles are often referred to as "role identities". In the case of these participants, many role identities (mother, wife, sibling, and teacher) exist. This study focuses primarily on their (science) teacher role identity. Literature on women's lives, as learners and teachers, suggest that women's experiences, currently and throughout history influenced their teacher role construction. There is however, little knowledge of women's lives as elementary teachers of science and the affect of their experiences, currently and throughout history, on their (science) teacher identity construction. Schools delineated by race, class, and gender relations, are similar to other sectors of society's, social and cultural spheres within which race, class, and gender identities are constructed. Using in-depth-interviews female elementary teachers were encouraged to actively reconstruct their life and work-life experiences focusing on family, school and science interactions. They addressed the intellectual and emotional connections between their life and work experiences by focusing on details of their past and present experiences and examining the meaning of those experiences. It was the scrutiny of these connections between their life and work experiences, the meaning derived from them and historical events, and the constraints imposed on their personal choices by broader power relations, such as those of class, race, and gender that informed why we teach, how we teach, and what we teach.

Widhitama, Y. N.; Lukito, A.; Khabibah, S.

2018-01-01

The aim of this research is to develop problem solving based learning materials on fraction for training creativity of elementary school students. Curriculum 2006 states that mathematics should be studied by all learners starting from elementary level in order for them mastering thinking skills, one of them is creative thinking. To our current knowledge, there is no such a research topic being done. To promote this direction, we initiate by developing learning materials with problem solving approach. The developed materials include Lesson Plan, Student Activity Sheet, Mathematical Creativity Test, and Achievement Test. We implemented a slightly modified 4-D model by Thiagajan et al. (1974) consisting of Define, Design, Development, and Disseminate. Techniques of gathering data include observation, test, and questionnaire. We applied three good qualities for the resulted materials; that is, validity, practicality, and effectiveness. The results show that the four mentioned materials meet the corresponding criteria of good quality product.

Measuring student engagement among elementary students: pilot of the Student Engagement Instrument--Elementary Version.

PubMed

Carter, Chandra P; Reschly, Amy L; Lovelace, Matthew D; Appleton, James J; Thompson, Dianne

2012-06-01

Early school withdrawal, commonly referred to as dropout, is associated with a plethora of negative outcomes for students, schools, and society. Student engagement, however, presents as a promising theoretical model and cornerstone of school completion interventions. The purpose of the present study was to validate the Student Engagement Instrument-Elementary Version (SEI-E). The psychometric properties of this measure were assessed based on the responses of an ethnically diverse sample of 1,943 students from an urban locale. Exploratory and confirmatory factor analyses indicated that the 4-factor model of student engagement provided the best fit for the current data, which is divergent from previous SEI studies suggesting 5- and 6-factor models. Discussion and implications of these findings are presented in the context of student engagement and dropout prevention. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

Engineering perceptions of female and male K-12 students: effects of a multimedia overview on elementary, middle-, and high-school students

NASA Astrophysics Data System (ADS)

Johnson, Amy M.; Ozogul, Gamze; DiDonato, Matt D.; Reisslein, Martin

2013-10-01

Computer-based multimedia presentations employing animated agents (avatars) can positively impact perceptions about engineering; the current research advances our understanding of this effect to pre-college populations, the main target for engineering outreach. The study examines the effectiveness of a brief computer-based intervention with animated agents in improving perceptions about engineering. Five hundred sixty-five elementary, middle-, and high-school students in the southwestern USA viewed a short computer-based multimedia overview of four engineering disciplines (electrical, chemical, biomedical, and environmental) with embedded animated agents. Students completed identical surveys measuring five subscales of engineering perceptions immediately before and after the intervention. Analyses of pre- and post-surveys demonstrated that the computer presentation significantly improved perceptions for each student group, and that effects were stronger for elementary school students, compared to middle- and high-school students.

Sampled-data chain-observer design for a class of delayed nonlinear systems

NASA Astrophysics Data System (ADS)

Kahelras, M.; Ahmed-Ali, T.; Giri, F.; Lamnabhi-Lagarrigue, F.

2018-05-01

The problem of observer design is addressed for a class of triangular nonlinear systems with not-necessarily small delay and sampled output measurements. One more difficulty is that the system state matrix is dependent on the un-delayed output signal which is not accessible to measurement, making existing observers inapplicable. A new chain observer, composed of m elementary observers in series, is designed to compensate for output sampling and arbitrary large delays. The larger the time-delay the larger the number m. Each elementary observer includes an output predictor that is conceived to compensate for the effects of output sampling and a fractional delay. The predictors are defined by first-order ordinary differential equations (ODEs) much simpler than those of existing predictors which involve both output and state predictors. Using a small gain type analysis, sufficient conditions for the observer to be exponentially convergent are established in terms of the minimal number m of elementary observers and the maximum sampling interval.

Painlevé equations, elliptic integrals and elementary functions

NASA Astrophysics Data System (ADS)

Żołądek, Henryk; Filipuk, Galina

2015-02-01

The six Painlevé equations can be written in the Hamiltonian form, with time dependent Hamilton functions. We present a rather new approach to this result, leading to rational Hamilton functions. By a natural extension of the phase space one gets corresponding autonomous Hamiltonian systems with two degrees of freedom. We realize the Bäcklund transformations of the Painlevé equations as symplectic birational transformations in C4 and we interpret the cases with classical solutions as the cases of partial integrability of the extended Hamiltonian systems. We prove that the extended Hamiltonian systems do not have any additional algebraic first integral besides the known special cases of the third and fifth Painlevé equations. We also show that the original Painlevé equations admit the first integrals expressed in terms of the elementary functions only in the special cases mentioned above. In the proofs we use equations in variations with respect to a parameter and Liouville's theory of elementary functions.

Modeling discrete combinatorial systems as alphabetic bipartite networks: theory and applications.

PubMed

Choudhury, Monojit; Ganguly, Niloy; Maiti, Abyayananda; Mukherjee, Animesh; Brusch, Lutz; Deutsch, Andreas; Peruani, Fernando

2010-03-01

Genes and human languages are discrete combinatorial systems (DCSs), in which the basic building blocks are finite sets of elementary units: nucleotides or codons in a DNA sequence, and letters or words in a language. Different combinations of these finite units give rise to potentially infinite numbers of genes or sentences. This type of DCSs can be represented as an alphabetic bipartite network (ABN) where there are two kinds of nodes, one type represents the elementary units while the other type represents their combinations. Here, we extend and generalize recent analytical findings for ABNs derived in [Peruani, Europhys. Lett. 79, 28001 (2007)] and empirically investigate two real world systems in terms of ABNs, the codon gene and the phoneme-language network. The one-mode projections onto the elementary basic units are also studied theoretically as well as in real world ABNs. We propose the use of ABNs as a means for inferring the mechanisms underlying the growth of real world DCSs.

2009-07-01

The large-molecules conformational transitions problem (the 'protein folding problem') is an open issue of vivid current science research work of fundamental importance for a number of modern science disciplines as well as for nanotechnology. Here, we elaborate the recently proposed quantum-decoherence-based approach to the issue. First, we emphasize a need for detecting the elementary quantum mechanical processes (whose combinations may give a proper description of the realistic experimental situations) and then we design such a model. As distinct from the standard approach that deals with the conformation system, we investigate the optically induced transitions in the molecule electrons system that, in effect, may give rise to a conformation change in the molecule. Our conclusion is that such a model may describe the comparatively slow conformational transitions.

Nature of the Physical Observer

Osoroma, Drahcir S.

2010-12-01

The nature of the observer has long plagued physical science. Here we review the current status of cognitive science in the context of a cosmology of mind in an Anthropic Multiverse. The concept of an élan vital or life force has long been considered the elementary action principle driving the evolution of living-systems by theologically minded scientists and individuals. Sufficiently extending Einstein's original model of a Static Universe, to a Holographic Anthropic Multiverse (HAM), provides a context for solving this centuries old problem for introducing this type of teleological principle into Physics, Biology, Medicine and Psychology. This means the contemporary framework of biological mechanism should no longer be considered the formal philosophical basis for describing living systems and contemporary allopathic (scientific) medicine. The new noetic action principle has far reaching implications for medicine and transpersonal psychology.

2016-12-01

Analogues of the elementary particles have been extensively searched for in condensed-matter systems for both scientific interest and technological applications. Recently, massless Dirac fermions were found to emerge as low-energy excitations in materials now known as Dirac semimetals. All of the currently known Dirac semimetals are non-magnetic with both time-reversal symmetry and inversion symmetry . Here we show that Dirac fermions can exist in one type of antiferromagnetic system, where both and are broken but their combination is respected. We propose orthorhombic antiferromagnet CuMnAs as a candidate, analyse the robustness of the Dirac points under symmetry protections and demonstrate its distinctive bulk dispersions, as well as the corresponding surface states, by ab initio calculations. Our results provide a possible platform to study the interplay of Dirac fermion physics and magnetism.

The Relationship Between Resilience and Internet Addiction: A Multiple Mediation Model Through Peer Relationship and Depression.

2017-10-01

Heavy use of the Internet may lead to profound academic problems in elementary students, such as poor grades, academic probation, and even expulsion from school. It is of great concern that Internet addiction problems in elementary school students have increased sharply in recent years. In this study, 58,756 elementary school students from the Henan province of China completed four questionnaires to explore the mechanisms of Internet addiction. The results showed that resilience was negatively correlated with Internet addiction. There were three mediational paths in the model: (a) the mediational path through peer relationship with an effect size of 50.0 percent, (b) the mediational path through depression with an effect size of 15.6 percent, (c) the mediational path through peer relationship and depression with an effect size of 13.7 percent. The total mediational effect size was 79.27 percent. The effect size through peer relationship was the strongest among the three mediation paths. The current findings suggest that resilience is a predictor of Internet addiction. Improving children's resilience (such as toughness, emotional control, and problem solving) can be an effective way to reduce Internet addiction behavior. The current findings provide useful information for early detection and intervention for Internet addiction.

Structure of weakly 2-dependent siphons

Deadlocks arising from insufficiently marked siphons in flexible manufacturing systems can be controlled by adding monitors to each siphon - too many for large systems. Li and Zhou add monitors to elementary siphons only while controlling the rest of (called dependent) siphons by adjusting control depth variables of elementary siphons. Only a linear number of monitors are required. The control of weakly dependent siphons (WDSs) is rather conservative since only positive terms were considered. The structure for strongly dependent siphons (SDSs) has been studied earlier. Based on this structure, the optimal sequence of adding monitors has been discovered earlier. Better controllability has been discovered to achieve faster and more permissive control. The results have been extended earlier to S3PGR2 (systems of simple sequential processes with general resource requirements). This paper explores the structures for WDSs, which, as found in this paper, involve elementary resource circuits interconnecting at more than (for SDSs, exactly) one resource place. This saves the time to compute compound siphons, their complementary sets and T-characteristic vectors. Also it allows us (1) to improve the controllability of WDSs and control siphons and (2) to avoid the time to find independent vectors for elementary siphons. We propose a sufficient and necessary test for adjusting control depth variables in S3PR (systems of simple sequential processes with resources) to avoid the sufficient-only time-consuming linear integer programming test (LIP) (Nondeterministic Polynomial (NP) time complete problem) required previously for some cases.

Social competence intervention for elementary students with Aspergers syndrome and high functioning autism.

2012-03-01

Despite frequent reports of academic success, individuals with high functioning autism or Aspergers Syndrome (HFA/AS) often manifest deficits in social abilities. These deficits can lead to daily difficulties, and negative long-term outcomes. Deficits in social competency are evident in this population from an early age, as children with HFA/AS present unique challenges relating to peers, interpreting complex contextual cues, and transitioning across settings. A paucity of social interventions exist that target elementary-age children with HFA/AS and their combination of core social competence deficit areas: theory of mind (ToM), emotional recognition, and executive functioning. The current study expanded on the Social Competence Intervention (for adolescents; SCI-A), as detailed in Stichter et al. (J Autism Dev Disorders 40:1067-1079, 2010), by adjusting the curriculum to meet the needs of an elementary population. Results indicate significant improvements on direct assessments measuring theory of mind and problem solving, and parent perceptions of overall social abilities and executive functioning for 20 students, aged 6-10, with HFA/AS. The elementary SCI program appears promising, however, additional replications are necessary including expansion to school settings.

Teacher perspectives on specialisation in the elementary classroom: implications for science instruction

Poland, Susan; Colburn, Amanda; Long, David E.

2017-09-01

In the current educational climate of testing and accountability, many elementary teachers find they lack adequate time and confidence to enact reform-based science teaching due to pressure to perform in reading and mathematics. With this tension in mind, we explore the phenomenon of elementary teacher specialisation in comparison to the traditional, generalist model of teaching, wherein a teacher is responsible for teaching all subjects to one group of students each year. This mixed-methods study examines teacher perspectives on the practice of specialisation and generalisation through teacher interview data. Our teachers spoke candidly about their attitudes towards specialisation, the perceived impacts of specialization on teachers and students, and the role of accountability, administration, and testing in their decisions to specialise. Additionally, our teachers discussed time dedicated to science in specialist and generalist classrooms. Our findings suggest that specialist roles are sought by those who see specialisation as a means of reducing workload, while allowing for content mastery and improved instruction. Alternatively, generalist roles are sought by those who primarily view the role of elementary teaching as the care and development of children, and who prefer to focus on the classroom as a holistic, fluid space. Implications for science teaching are discussed.

Being a Scientist While Teaching Science: Implementing Undergraduate Research Opportunities for Elementary Educators

Hock, Emily; Sharp, Zoe

2016-03-01

Aspiring teachers and current teachers can gain insight about the scientific community through hands-on experience. As America's standards for elementary school and middle school become more advanced, future and current teachers must gain hands-on experience in the scientific community. For a teacher to be fully capable of teaching all subjects, they must be comfortable in the content areas, equipped to answer questions, and able to pass on their knowledge. Hands-on research experiences, like the Summer Astronomy Research Experience at California Polytechnic University, pair liberal studies students with a cooperative group of science students and instructors with the goal of doing research that benefits the scientific community and deepens the team members' perception of the scientific community. Teachers are then able to apply the basic research process in their classrooms, inspire students to do real life science, and understand the processes scientists' undergo in their workplace.

Elementary Teachers' Selection and Use of Visual Models

NASA Astrophysics Data System (ADS)

Lee, Tammy D.; Gail Jones, M.

2018-02-01

As science grows in complexity, science teachers face an increasing challenge of helping students interpret models that represent complex science systems. Little is known about how teachers select and use models when planning lessons. This mixed methods study investigated the pedagogical approaches and visual models used by elementary in-service and preservice teachers in the development of a science lesson about a complex system (e.g., water cycle). Sixty-seven elementary in-service and 69 elementary preservice teachers completed a card sort task designed to document the types of visual models (e.g., images) that teachers choose when planning science instruction. Quantitative and qualitative analyses were conducted to analyze the card sort task. Semistructured interviews were conducted with a subsample of teachers to elicit the rationale for image selection. Results from this study showed that both experienced in-service teachers and novice preservice teachers tended to select similar models and use similar rationales for images to be used in lessons. Teachers tended to select models that were aesthetically pleasing and simple in design and illustrated specific elements of the water cycle. The results also showed that teachers were not likely to select images that represented the less obvious dimensions of the water cycle. Furthermore, teachers selected visual models more as a pedagogical tool to illustrate specific elements of the water cycle and less often as a tool to promote student learning related to complex systems.

The elementary events of Ca2+ release elicited by membrane depolarization in mammalian muscle.

Csernoch, L; Zhou, J; Stern, M D; Brum, G; Ríos, E

2004-05-15

Cytosolic [Ca(2+)] transients elicited by voltage clamp depolarization were examined by confocal line scanning of rat skeletal muscle fibres. Ca(2+) sparks were observed in the fibres' membrane-permeabilized ends, but not in responses to voltage in the membrane-intact area. Elementary events of the depolarization-evoked response could be separated either at low voltages (near -50 mV) or at -20 mV in partially inactivated cells. These were of lower amplitude, narrower and of much longer duration than sparks, similar to 'lone embers' observed in the permeabilized segments. Their average amplitude was 0.19 and spatial half-width 1.3 microm. Other parameters depended on voltage. At -50 mV average duration was 111 ms and latency 185 ms. At -20 mV duration was 203 ms and latency 24 ms. Ca(2+) release current, calculated on an average of events, was nearly steady at 0.5-0.6 pA. Accordingly, simulations of the fluorescence event elicited by a subresolution source of 0.5 pA open for 100 ms had morphology similar to the experimental average. Because 0.5 pA is approximately the current measured for single RyR channels in physiological conditions, the elementary fluorescence events in rat muscle probably reflect opening of a single RyR channel. A reconstruction of cell-averaged release flux at -20 mV based on the observed distribution of latencies and calculated elementary release had qualitatively correct but slower kinetics than the release flux in prior whole-cell measurements. The qualitative agreement indicates that global Ca(2+) release flux results from summation of these discrete events. The quantitative discrepancies suggest that the partial inactivation strategy may lead to events of greater duration than those occurring physiologically in fully polarized cells.

Seroepidemiology of pertussis among elementary school children in northern Taiwan.

Pertussis has been considered a vaccine-preventable "childhood disease", but a shift in age distribution has been reported worldwide. We conducted a seroepidemiological study in 2013 in Taiwan to elucidate the seroprevalence of pertussis among elementary school children. With a multilevel randomized method, which included 14 variables (4 population variables, 4 socio-educational variables, and 6 medical facilities' variables), the 29 executive districts of New Taipei City, Taiwan, were categorized into five strata. From each stratum, the number of school children as well as the number of elementary schools were proportionally selected. Enzyme immunoassay was applied for pertussis immunoglobulin-G measurement. A total of 936 children from 14 schools were recruited. Most participants (98.89%) received at least three doses of acellular diphtheria-tetanus-pertussis vaccine. The overall seropositive rate for pertussis was 33.97%. The seropositive rate was highest for students in Grade 1 (49.36%) and then declined with time, except for Grade 6 students. Students from Grade 1 to Grade 4 had a significant higher seropositive rate (37.18% vs. 27.56%, p = 0.002) than those from Grade 5 to Grade 6, but a lower geometric mean titer (18.71 NovaTec Unit/mL vs. 20.04 NovaTec Unit/mL, p = 0.20). For the class grades, geometric mean titers were positively correlated with seroprevalence (p < 0.005). Currently, almost one-third of elementary school children in Taiwan were seropositive for pertussis, a rate lower than expected. Seroprevalence declined with increasing class grades except for Grade 6. The current national immunization program may not provide adequate protection for children against pertussis.

From inside the black box: Teacher perceptions of science instruction at the elementary level

NASA Astrophysics Data System (ADS)

Ferrini, Cynthia D.

Science education reform projects aimed at elementary school children arose in the 1960's. The most prevalent of these reforms utilized the inquiry, or hands-on, science method. Billions of dollars have been invested in these reforms. Yet, reports indicate that science is not being taught at the level one might expect in elementary schools. This research was an analysis of the problems and concerns teachers at one school district faced as they tried to implement and sustain elementary inquiry science instruction. The district chosen was a large suburban district in the Western United States. The population was ninety percent Caucasian with a slightly more ethnically diverse school population. This district was chosen because it had an elementary science program for over twenty years and had received national acclaim for that program. The district had a stable and homogeneous staff there was a low administrator and teacher turnover rate and the elementary teaching population was ninety percent Caucasian and ninety percent female. Interviews with administrators and teachers were conducted. Data were collected from focus groups of teachers and science partners. Observations of elementary science classroom instruction and professional development sessions were made. Results of this research indicated that one important key to elementary science reform rests in the hands of teachers. Once the door to the classroom is closed, the teacher can decide to teach or not to teach science. The findings of this research illustrate that teachers hold ideas about science and science instruction that are antithetical to some tenets of inquiry science. Until these ideas are addressed it will be difficult, if not impossible, to implement a systemic elementary inquiry science program. This study demonstrates that professional development for elementary teachers in science needs to change from a focus on the mechanical usage of individual units to a focus on teacher expectations for student achievement. Professional development for teachers in inquiry science must address the cognitive foundations for inquiry science and the benefits students derive from this educational approach. Institutions delivering pre-service training for elementary teachers in science must change the curriculum to reflect these needs.

Shape-shifting colloids via stimulated dewetting

2016-01-01

The ability to reconfigure elementary building blocks from one structure to another is key to many biological systems. Bringing the intrinsic adaptability of biological systems to traditional synthetic materials is currently one of the biggest scientific challenges in material engineering. Here we introduce a new design concept for the experimental realization of self-assembling systems with built-in shape-shifting elements. We demonstrate that dewetting forces between an oil phase and solid colloidal substrates can be exploited to engineer shape-shifting particles whose geometry can be changed on demand by a chemical or optical signal. We find this approach to be quite general and applicable to a broad spectrum of materials, including polymers, semiconductors and magnetic materials. This synthetic methodology can be further adopted as a new experimental platform for designing and rapidly prototyping functional colloids, such as reconfigurable micro swimmers, colloidal surfactants and switchable building blocks for self-assembly.

Mars Atmosphere and Volatile EvolutioN (MAVEN) mission's Red Planet program: Bridging the gap in elementary school science through climate studies of Mars

NASA Astrophysics Data System (ADS)

Wood, E. L.

2012-12-01

Although reading, writing, and math examinations are often conducted early in elementary school, science is not typically tested until 4th or 5th grade. The result is a refocus on the tested topics at the expense of the untested ones, despite that standards exist for each topic at all grades. On a national level, science instruction is relegated to a matter of a few hours per week. A 2007 Education Policy study states that elementary school students spend an average of 178 minutes a week on science while spending 500 minutes on literacy. A recent NSTA report in July of 2011 of elementary and middle school teachers confirms that teachers feel pressured to teach math and literacy at the expense of other programs. In our interaction with elementary teachers, it is also apparent that many are uncomfortable with science concepts. In order for us to successfully address the Next Generation Science Standards, teachers must be able to reconcile all of the different requirements placed on them in a given school day and in a given school environment. A unique way to combat the lack of science instruction at elementary grades is to combine literacy into an integrated science program, thereby increasing the number of science contact hours. The Red Planet: Read, Write, Explore program, developed for the MAVEN mission, is a science, art, and literacy program designed to easily fit into a typical 3rd-5th grade instructional day. Red Planet tackles climate change through Mars' geologic history and makes Mars-Earth comparisons, while encouraging students to reflect on the environmental requirements needed to keep a biological organisms (including humans) happy, healthy, and alive. The Red Planet program is currently being pilot tested at Acres Green Elementary School in Colorado.

Teaching science as argument: Prospective elementary teachers' knowledge

NASA Astrophysics Data System (ADS)

Barreto-Espino, Reizelie

For the past two decades there has been increasing emphasis on argumentation in school science. In 2007, the National Research Council published a synthesis report that emphasizes the centrality of constructing, evaluating, and using scientific explanations. Participating in argumentation is seen as fundamental to children's science learning experiences. These new expectations increase challenges for elementary teachers since their understanding of and experiences with science are overwhelmingly inconsistent with teaching science as argument. These challenges are further amplified when dealing with prospective elementary teachers. The current study was guided by the following research questions: (1) What are the ways in which preservice elementary teachers appropriate components of "teaching science as argument" during their student teaching experience? (2) To what extent do components from prospective elementary teachers' reflections influence planning for science teaching? (3) What elements from the context influence preservice elementary teachers' attention to teaching science as argument? This study followed a multi-participant case study approach and analyses were informed by grounded theory. Three participants were selected from a larger cohort of prospective elementary teachers enrolled in an innovative Elementary Professional Development School (PDS) partnership at a large Northeast University. Cross-case analysis allowed for the development of five key assertions: (1) The presence of opportunities for interacting with phenomena and collecting first hand data helped participants increase their emphasis on evidence-based explanations. (2) Participants viewed science talks as an essential mechanism for engaging students in the construction of evidence-based explanations and as being fundamental to meaning-making. (3) Participants demonstrated attention to scientific subject matter during instruction rather than merely focusing on activities and/or inquiry processes. (4) Scaffolded protocols positively influenced participants' attention to having students construct evidence-based explanations during science planning and teaching. (5) Teachers' beliefs about children's science capabilities influence their attention to and adoption of practices associated with teaching science as argument. Findings are discussed in terms of their implications for teacher education, such as the use of coherent conceptual frameworks to guide coursework and field experiences and the development of video-based cases that represent "images of the possible" associated with challenging reform-oriented teaching practices.

Blachowicz, T; Ehrmann, A

2013-01-01

The influence of a variation of spatial relative orientations onto the coupling dynamics and subsequent magnetic anisotropies was modeled in ferromagnetic nanowires. The wires were analyzed in the most elementary configurations, thus, arranged in pairs perpendicular to each other, leading to one-dimensional (linear) and zero-dimensional (point-like) coupling. Different distances within each elementary pair of wires and between the pairs give rise to varying interactions between parallel and perpendicular wires, respectively. Simulated coercivities show an exchange of easy and hard axes for systems with different couplings. Additionally, two of the systems exhibit a unique switching behavior which can be utilized for developing new functionalities.

A workload model and measures for computer performance evaluation

NASA Technical Reports Server (NTRS)

Kerner, H.; Kuemmerle, K.

1972-01-01

A generalized workload definition is presented which constructs measurable workloads of unit size from workload elements, called elementary processes. An elementary process makes almost exclusive use of one of the processors, CPU, I/O processor, etc., and is measured by the cost of its execution. Various kinds of user programs can be simulated by quantitative composition of elementary processes into a type. The character of the type is defined by the weights of its elementary processes and its structure by the amount and sequence of transitions between its elementary processes. A set of types is batched to a mix. Mixes of identical cost are considered as equivalent amounts of workload. These formalized descriptions of workloads allow investigators to compare the results of different studies quantitatively. Since workloads of different composition are assigned a unit of cost, these descriptions enable determination of cost effectiveness of different workloads on a machine. Subsequently performance parameters such as throughput rate, gain factor, internal and external delay factors are defined and used to demonstrate the effects of various workload attributes on the performance of a selected large scale computer system.

Preparation and in vitro and in vivo evaluation of vinpocetine (VIN) elementary osmotic pump (EOP) formulations were investigated. A method for the preparation of VIN elementary osmotic pump tablet was obtained by adding organic acid additives to increase VIN solubility. VIN was used as the active pharmaceutical ingredient, lactose and mannitol as osmotic agent. Citric acid was used as increasing API solubility and without resulting in the API degradation. It is found that the VIN release rate was increasing with the citric acid amount at a constant range. Cellulose acetate 398-3 was employed as semipermeable membrane containing polyethylene glycol 6000 and diethyl-o-phthalate as pore-forming agent and plasticizer for controlling membrane permeability. In addition, a clear difference between the pharmacokinetic patterns of VIN immediate release and VIN elementary osmotic pump formulations was revealed. The area under the plasma concentration-time curve after oral administration of elementary osmotic pump formulations was equivalent to VIN immediate release formulation. Furthermore, significant differences found for mean residence time, elimination half-life, and elimination rate constant values corroborated prolonged release of VIN from elementary osmotic pump formulations. These results suggest that the VIN osmotic pump controlled release tablets have marked controlled release characters and the VIN osmotic pump controlled release tablets and the normal tablets were bioequivalent.

Modeling, simulation and optimization of a no-chamber solid oxide fuel cell operated with a flat-flame burner

NASA Astrophysics Data System (ADS)

Vogler, Marcel; Horiuchi, Michio; Bessler, Wolfgang G.

A detailed computational model of a direct-flame solid oxide fuel cell (DFFC) is presented. The DFFC is based on a fuel-rich methane-air flame stabilized on a flat-flame burner and coupled to a solid oxide fuel cell (SOFC). The model consists of an elementary kinetic description of the premixed methane-air flame, a stagnation-point flow description of the coupled heat and mass transport within the gas phase, an elementary kinetic description of the electrochemistry, as well as heat, mass and charge transport within the SOFC. Simulated current-voltage characteristics show excellent agreement with experimental data published earlier (Kronemayer et al., 2007 [10]). The model-based analysis of loss processes reveals that ohmic resistance in the current collection wires dominates polarization losses, while electronic loss currents in the mixed conducting electrolyte have only little influence on the polarized cell. The model was used to propose an optimized cell design. Based on this analysis, power densities of above 200 mW cm -2 can be expected.

The purposes of this study were to further the understanding of how preservice teacher construct teacher knowledge and pedagogical content knowledge of elementary mathematics and science and to determine the extent of that knowledge in a school-based setting. Preservice teachers, university instructors, inservice teachers, and other school personnel were involved in this context-specific study. Evidence of the preservice teachers' knowledge construction (its acquisition, its dimensions, and the social context) was collected through the use of a qualitative methodology. Collected data included individual and group interviews, course documents, artifacts, and preservice teaching portfolios. Innovative aspects of this integrated mathematics and science elementary methods course included standards-based instruction with immediate access to field experiences. Grade-level teams of preservice and inservice teachers planned and implemented lessons in mathematics and science for elementary students. An on-site, portable classroom building served as a mathematics and science teaching and learning laboratory. A four-stage analysis was performed, revealing significant patterns of learning. An ecosystem of learning within a constructivist learning environment was identified to contain three systems: the university system; the school system; and the cohort of learners system. A mega system for the construction of teacher knowledge was revealed in the final analysis. Learning venues were discovered to be the conduits of learning in a situated learning context. Analysis and synthesis of data revealed an extensive acquisition of teacher knowledge and pedagogical content knowledge through identified learning components. Patience, flexibility, and communication were identified as necessities for successful teaching. Learning components included: collaboration with inservice teachers; implementation of discovery learning and hands-on/minds-on learning; small groupwork; lesson planning; classroom management; and application of standards-based instruction. Prolonged, extensive classroom involvement provided familiarity with the ability levels of elementary students. Gains in positive attitudes and confidence in teaching mathematics and science were identified as direct results of this experience. This may be attributed to the immersion in the school-based setting (hands-on) and the standards-based approach (minds-on) methods course. The results are written in case study form using thick description with an emphasis on preservice teachers.
