  2. Astronomy Remote Observing Research Projects of US High School Students

    NASA Astrophysics Data System (ADS)

    Kadooka, M.; Meech, K. J.

    2006-08-01

    In order to address the challenging climate for promoting astronomy education in the high schools we have used astronomy projects to give students authentic research experiences in order to encourage their pursuit of science and technology careers. Initially, we conducted teacher workshops to develop a cadre of teachers who have been instrumental in recruiting students to work on projects. Once identified, these students have been motivated to conduct astronomy research projects with appropriate guidance. Some have worked on these projects during non-school hours and others through a research course. The goal has been for students to meet the objectives of inquiry-based learning, a major US National Science Standard. Case studies will be described using event-based learning with the NASA Deep Impact mission. Hawaii students became active participants investigating comet properties through the NASA Deep Impact mission. The Deep Impact Education and Public Outreach group developed materials which were used by our students. After learning how to use image processing software, these students obtained Comet 9P/ Tempel 1 images in real time from the remote observing Faulkes Telescope North located on Haleakala, Maui for their projects. Besides conducting event-based projects which are time critical, Oregon students have worked on galaxies and sunspots projects. For variable star research, they used images obtained from the remote observing offline mode of Lowell Telescope located in Flagstaff, Arizona. Essential to these projects has been consistent follow-up required for honing skills in observing, image processing, analysis, and communication of project results through Science Fair entries. Key to our success has been the network of professional and amateur astronomers and educators collaborating in a multiplicity of ways to mentor our students. This work-in-progress and process will be shared on how to inspire students to pursue careers in science and technology with

The students, chosen from Sonoma County high schools in a competitive selection process, work in various science, technology, engineering, and mathematics (STEM) fields throughout the School of Science and Technology at SSU. The two interns sponsored by the EPO Group each summer monitor active galaxies using GORT, the NASA/Fermi-sponsored optical robotic telescope operated by the Group. They are mentored in their projects by EPO Group personnel and by SSU undergraduates who have experience with the telescope. The students learn about the sky, telescopes and the active galaxies they observe. They also learn how to make telescopic observations and how to reduce the CCD images obtained. Interns also participate in weekly meetings with other interns working on different projects around campus. At the end of the summer all the interns present their research results at a symposium held on campus.The symposium is attended by the interns themselves, their parents, their high school science teachers, and university faculty and administrators.The program has had a positive impact on how our interns view science, and specifically on their view of astronomy, as reported by the interns themselves in the first two years of the program.

  11. Teaching massage to nursing students of geriatrics through active learning.

    PubMed

    Adler, Patricia A

    2009-03-01

    The use of massage in nursing practice has declined through the years in favor of high-tech interventions. This article describes a project using active learning to teach nursing students massage with dementia residents in assisted living. Students participated in a workshop to practice basic relaxation massage techniques with the guidance of their clinical instructor and then provided massages to resident volunteers. Afterward, students discussed their experience and completed a resident assessment form. The students requested more such activities, and the residents and facility management invited the students to return for another session. The instructor observed growth in the students' assessment skills and in their confidence. Use of massage to teach nursing students how to care for and relate to older adults with cognitive impairment is recommended. Further research is needed on the use of massage as an active learning method for nursing students in long-term care. PMID:19181909

    NASA Technical Reports Server (NTRS)

    Neugebauer, G.; Soifer, B. T.; Rowan-Robinson, M.

    1985-01-01

    The IRAS survey gives an unbiased view of the infrared properties of the active galaxies. Seyfert galaxies occupy much the same area in color-color plots as to normal infrared bright galaxies, but extend the range towards flatter 60 to 25 mm slopes. Statistically the Seyfert 1 galaxies can be distinguished from the Seyfert 2 galaxies, lying predominantly closer to the area with constant slopes between 25 and 200 mm. The infrared measurements of the Seyfert galaxies cannot distinguish between the emission mechanisms in these objects although they agree with the currently popular ideas; they do provide a measure of the total luminosity of the Seyferts. The quasar's position in the color-color diagrams continue the trend of the Seyferts. The quasar 3C48 is shown to be exceptional among the radio loud quasars in that it has a high infrared luminosity which dominates the power output of the quasar and is most likely associated with the underlying host galaxy.

    NASA Technical Reports Server (NTRS)

    Chambers, Lin H.; Costulis, P. Kay; Young, David F.; Rogerson, Tina M.

    2004-01-01

    The Students' Cloud Observations On-Line (S'COOL) Project was initiated in 1997 to obtain student observations of clouds coinciding with the overpass of the Clouds and the Earth's Radiant Energy System (CERES) instruments on NASA's Earth Observing System satellites. Over the past seven years we have accumulated more than 9,000 cases worldwide where student observations are available within 15 minutes of a CERES observation. This paper reports on comparisons between the student and satellite data as one facet of the validation of the CERES cloud retrievals. Available comparisons include cloud cover, cloud height, cloud layering, and cloud visual opacity. The large volume of comparisons allows some assessment of the impact of surface cover, such as snow and ice, reported by the students. The S'COOL observation database, accessible via the Internet at http://scool.larc.nasa.gov, contains over 32,000 student observations and is growing by over 700 observations each month. Some of these observations may be useful for assessment of other satellite cloud products. In particular, some observing sites have been making hourly observations of clouds during the school day to learn about the diurnal cycle of cloudiness.

  6. Observance of ethical codes in selecting supervisor by postgraduate students.

    PubMed

    Bayrami, Zahra; Abdollahi, Mohammad

    2011-01-01

    Nowadays, with development of medical sciences, several ethical challenges have raised which make research more complicated. Observance of student's right in selecting interested research topic and the supervisor, in addition to its positive effect on the research process, will cause satisfaction and quality promotion in the educational system. To observe that issue, during a confidential survey of a number of postgraduate students in 2009, students were asked to confidentially describe any displeasure they might get during their study and research. The most important items included: imposing thesis by a supervisor without informing the student, compulsory assignment of students to a specific supervisor, little time allocated for students by the supervising team who may be selected without students interests, prolongation of the research time, and non-cooperation in publishing the results. Establishment of a proper way to transfer student's displeasure or criticism to supervisors and establishing a continuous program for informing research teams including supervisors and students about ethical codes can positively affect the issue.

    2003-12-01

    For this project, we validated the Moderate Resolution Imaging Spectroradiometer (MODIS) snow product and cloud masking algorithms using GLOBE student, SATELLITES (a K-12 program developed at the University of Toledo) and National Weather Service (NWS) Cooperative Extension observations. The study area is the lower Great Lakes region that includes the lake effect snowbelt areas to the east of Lakes Michigan and Erie. Student observations were taken during intense field campaigns with the winter of 2001-2002 having very little snow and 2000-2001 and 2002-2003 having significant snow cover. The student observers are able to gather data over a large spatial area that would be difficult to obtain through other means. In addition, the students collected snow as well as cloud data near the satellite overpass time as well as snow water equivalent that is an improvement over the NWS cooperative station data that is just snow depth. Quantitative analysis of the Version 4 MODIS snow algorithm produced an accuracy of 94 percent when compared to student observations. The largest errors were associated with partly cloudy conditions. A qualitative study was performed by a tenth grade student and her teacher at St. Ursula's Academy in Toledo found that the snow product produces errors when there are different levels of clouds in the images.

    2015-01-01

    One econometric rule of thumb is that greater dispersion in observations of the independent variable improves estimates of regression coefficients and therefore produces better results, i.e., lower standard errors of the estimates. Nevertheless, students often seem to mistrust precisely the observations that contribute the most to this greater…

    True, C. M.

    2006-06-01

    For over thirty years the College of Charleston has been teaching a year-long introductory astronomy course incorporating a mandatory 3 hour lab. Despite our location in a very light polluted, coastal, high humidity, and often cloudy metropolitan area we have emphasized observational activities as much as possible. To accommodate our population of between 300-400 students per semester, we have 28 8-inch Celestron Telescopes and 25 GPS capable 8-inch Meade LX-200 telescopes. Finally, we have a 16 DFM adjacent to our rooftop observing decks. For indoor activities we have access to 42 computers running a variety of astronomy education software. Some of the computer activities are based on the Starry Night software (Backyard and Pro), the CLEA software from Gettysburg College, and Spectrum Explorer from Boston University. Additionally, we have labs involving cratering, eclipses and phases, coordinate systems with celestial globes, the inverse square law, spectroscopy and spectral classification, as well as others. In this presentation we will discuss the difficulties in managing a program of this size. We have approximately 14 lab sections a week. The lab manager's task involves coordinating 8-10 lab instructors and the same number of undergraduate teaching assistants as well as trying to maintain a coherent experience between the labs and lecture sections. Our lab manuals are produced locally with yearly updates. Samples from the manuals will be available. This program has been developed by a large number of College of Charleston astronomy faculty, including Don Drost, Bob Dukes, Chris Fragile, Tim Giblin, Jon Hakkila, Bill Kubinec, Lee Lindner, Jim Neff, Laura Penny, Al Rainis, Terry Richardson, and D. J. Williams, as well as adjunct and visiting faculty Bill Baird, Kevin Bourque, Ethan Denault, Kwayera Davis, Francie Halter, and Alan Johnson. Part of this work has been funded by NSF DUE grants to the College of Charleston.

    2014-01-01

    Background: In order to improve our understanding of the relationship between the built environment and physical activity, it is important to identify associations between specific geographic characteristics and physical activity behaviors. Purpose: Examine relationships between observed physical activity behavior and measures of the built environment collected on 291 street segments in Indianapolis and St. Louis. Methods: Street segments were selected using a stratified geographic sampling design to ensure representation of neighborhoods with different land use and socioeconomic characteristics. Characteristics of the built environment on-street segments were audited using two methods: in-person field audits and audits based on interpretation of Google Street View imagery with each method blinded to results from the other. Segments were dichotomized as having a particular characteristic (e.g., sidewalk present or not) based on the two auditing methods separately. Counts of individuals engaged in different forms of physical activity on each segment were assessed using direct observation. Non-parametric statistics were used to compare counts of physically active individuals on each segment with built environment characteristic. Results: Counts of individuals engaged in physical activity were significantly higher on segments with mixed land use or all non-residential land use, and on segments with pedestrian infrastructure (e.g., crosswalks and sidewalks) and public transit. Conclusion: Several micro-level built environment characteristics were associated with physical activity. These data provide support for theories that suggest changing the built environment and related policies may encourage more physical activity. PMID:24904916

    Berk, Ronald A; Naumann, Phyllis L; Appling, Susan E

    2004-01-01

    Peer observation of classroom and clinical teaching has received increased attention over the past decade in schools of nursing to augment student ratings of teaching effectiveness. One essential ingredient is the scale used to evaluate performance. A five-step systematic procedure for adapting, writing, and building any peer observation scale is described. The differences between the development of a classroom observation scale and an appraisal scale to observe clinical instructors are examined. Psychometric issues peculiar to observation scales are discussed in terms of content validity, eight types of response bias, and interobserver reliability. The applications of the scales in one school of nursing as part of the triangulation of methods with student ratings and the teaching portfolio are illustrated. Copies of the scales are also provided. PMID:16646875

    Cole, Merryn; Wilhelm, Jennifer; Yang, Hongwei

    2015-07-01

    Relationships between sixth grade students' moon journaling and students' spatial-scientific reasoning after implementation of an Earth/Space unit were examined. Teachers used the project-based Realistic Explorations in Astronomical Learning curriculum. We used a regression model to analyze the relationship between the students' Lunar Phases Concept Inventory (LPCI) post-test score variables and several predictors, including moon journal score, number of moon journal entries, student gender, teacher experience, and pre-test score. The model shows that students who performed better on moon journals, both in terms of overall score and number of entries, tended to score higher on the LPCI. For every 1 point increase in the overall moon journal score, participants scored 0.18 points (out of 20) or nearly 1% point higher on the LPCI post-test when holding constant the effects of the other two predictors. Similarly, students who increased their scores by 1 point in the overall moon journal score scored approximately 1% higher in the Periodic Patterns (PP) and Geometric Spatial Visualization (GSV) domains of the LPCI. Also, student gender and teacher experience were shown to be significant predictors of post-GSV scores on the LPCI in addition to the pre-test scores, overall moon journal score, and number of entries that were also significant predictors on the LPCI overall score and the PP domain. This study is unique in the purposeful link created between student moon observations and spatial skills. The use of moon journals distinguishes this study further by fostering scientific observation along with skills from across science, technology, engineering, and mathematics disciplines.

    The Reformed Teaching Observation Protocol (RTOP; Swada, et al., 2002) has been used by a trained team of On the Cutting Edge (CE) observers to characterize the degree of student-centered teaching in US college and university geoscience classrooms. Total RTOP scores are derived from scores on 25 rubric items used to characterize teaching practices in categories of lesson design, content delivery, student-instructor and student-student interactions. More than 200 classroom observations have been completed by the RTOP team in undergraduate courses at a variety of US institution types (e.g., community colleges, research universities). A balanced mix of early career, mid-career, and veteran faculty are included, and the study examines class sizes ranging from small (<30) to large (>80 students). Observations are limited to one class session and do not include laboratories or field activities. Data include RTOP scores determined by a trained observer during the classroom observation and an online survey in which the observed instructors report on their teaching practices. RTOP scores indicate that the observed geoscience classes feature varying degrees of student-centered teaching, with 30% of observed classes categorized as teacher-centered (RTOP scores ≤30), 45% of observed classes categorized as transitional classrooms (RTOP scores 31-49) and 25% are student-centered (RTOP scores ≥ 50). Instructor self-report survey data and RTOP scores indicate that geoscience faculty who have participated in one or more CE professional development event and use the CE website have an average RTOP score of 49, which is significantly higher (> 15 points) than the average score of faculty who have not participated in CE events and have not used the website. Approximately 60% of student-centered classes (those with high RTOP scores) use some traditional lecture nearly every day, but are also are likely to include an in-class activity or group discussion (e.g. Think

    As scientists and engineers primarily employed by the public, we have a responsibility to "communicate the results of our research so that the average American could understand that NASA is an investment in our future...". Not only are we employed by the public, but they are also the source of future generations of scientists and engineers. Teachers typically don't have the time or expertise to research recent advances in space science and reduce them to a form that students can absorb. Teachers are also often intimidated by both the subject and the researchers themselves. Therefore, the burden falls on us - the space scientists and engineers of the world - to communicate our findings in ways both teachers and students can understand. Student Nanoexperiments for Outreach and Observational Planetary InquirY (SNOOPY) provides just such an opportunity to directly involve our customers in planetary science missions.

  15. HEROES Observations of a Quiescent Active Region

    NASA Astrophysics Data System (ADS)

    Shih, A. Y.; Christe, S.; Gaskin, J.; Wilson-Hodge, C.

    2014-12-01

    Hard X-ray (HXR) observations of solar flares reveal the signatures of energetic electrons, and HXR images with high dynamic range and high sensitivity can distinguish between where electrons are accelerated and where they stop. Even in the non-flaring corona, high-sensitivity HXR measurements may be able to detect the presence of electron acceleration. The High Energy Replicated Optics to Explore the Sun (HEROES) balloon mission added the capability of solar observations to an existing astrophysics balloon payload, HERO, which used grazing-incidence optics for direct HXR imaging. HEROES measures HXR emission from ~20 to ~75 keV with an angular resolution of 33" HPD. HEROES launched on 2013 September 21 from Fort Sumner, New Mexico, and had a successful one-day flight. We present the detailed analysis of the 7-hour observation of AR 11850, which sets new upper limits on the HXR emission from a quiescent active region, with corresponding constraints on the numbers of tens of keV energetic electrons present. Using the imaging capability of HEROES, HXR upper limits are also obtained for the quiet Sun surrounding the active region. We also discuss what can be achieved with new and improved HXR instrumentation on balloons.

    Zong, W. G.; Tang, Y. H.; Fang, C.; Xu, A. A.

    An active region filament was well observed on September 4, 2002 with THEMIS at the Teide observatory and SOHO/MDI. The full Stokes parameters of the filament were obtained in Hα and FeI 6302 Å lines. Using the data, we have studied the fine structure of the filament and obtained the parameters at the barb endpoints, including intensity, velocity and longitudinal magnetic field. Our results indicate: (a) the Doppler velocities are quiet different at barb endpoints; (b) the longitudinal magnetic fields at the barb endpoints are very weak; (c) there is a strong magnetic field structure under the filament spine.

  18. Astronomy Student Activities Using Stellarium Software

    NASA Astrophysics Data System (ADS)

    Benge, Raymond D.; Tuttle, S. R.

    2012-01-01

    Planetarium programs can be used to provide a valuable learning experience for introductory astronomy students. Educational activities can be designed to utilize the capabilities of the software to display the sky, coordinates, motions in the sky, etc., in order to learn basic astronomical concepts. Most of the major textbook publishers have an option of bundling planetarium software and even laboratory activities using such software with textbooks. However, commercial planetarium software often is updated on a different schedule from the textbook revision and new edition schedule. The software updates also sometimes occur out of sync with college textbook adoption deadlines. Changes in software and activity curriculum often translate into increases costs for students and the college. To provide stability to the process, faculty at Tarrant County College have developed a set of laboratory exercises, entitled Distant Nature, using free open source Stellarium software. Stellarium is a simple, yet powerful, program that is available in formats that run on a variety of operating systems (Windows, Apple, linux). A web site was developed for the Distant Nature activities having a set version of Stellarium that students can download and install on their own computers. Also on the web site, students can access the instructions and worksheets associated with the various Stellarium based activities. A variety of activities are available to support two semesters of introductory astronomy. The Distant Nature web site has been used for one year with Tarrant County College astronomy students and is now available for use by other institutions. The Distant Nature web site is http://www.stuttle1.com/DN_Astro/index.html .

    MErcury Surface, Space ENviroment, GEochemistry, and Ranging (MESSENGER) magnetic field and plasma measurements taken during crossings of Mercury's magnetotail from 2011 to 2014 have been investigated for substorms. A number of events with clear Earth-like growth phase and expansion phase signatures were found. The thinning of the plasma sheet and the increase of magnetic field intensity in the lobe were observed during the growth phase and plasma sheet was observed to thicken during the expansion phase, which are similar to the observations at Earth. But the time scale of Mercury's substorm is only several minutes comparing with the several hours at Earth [Sun et al., 2015a]. Detailed analysis of magnetic field fluctuations during the substorm expansion phase have revealed low frequency plasma waves, e.g. Pi2-like pulsations. The By fluctuations accompanying substorm dipolarizations are consistent with pulses of field-aligned currents near the high latitude edge of the plasma sheet. Further study shows that they are near-circularly polarized electromagnetic waves, most likely Alfvén waves. Soon afterwards the plasma sheet thickened and MESSENGER detected a series of compressional waves. We have also discussed their possible sources [Sun et al., 2015b]. Sun, W.-J., J. A. Slavin, S. Y.

  20. Student Active Learning Methods in Physical Chemistry

    NASA Astrophysics Data System (ADS)

    Hinde, Robert J.; Kovac, Jeffrey

    2001-01-01

    We describe two strategies for implementing active learning in physical chemistry. One involves supplementing a traditional lecture course with heavily computer-based active-learning exercises carried out by cooperative groups in a department computer lab. The other uses cooperative learning almost exclusively, supplemented by occasional mini-lectures. Both approaches seemed to result in better student learning and a more positive attitude toward the subject. On the basis of our respective experiences using active learning techniques, we discuss some of the strengths of these techniques and some of the challenges we encountered using the active-learning approach in teaching physical chemistry.

  7. Observations of seismic activity in Southern Lebanon

    Meirova, T.; Hofstetter, R.

    2013-04-01

    Recent seismic activity in southern Lebanon is of particular interest since the tectonic framework of this region is poorly understood. In addition, seismicity in this region is very infrequent compared with the Roum fault to the east, which is seismically active. Between early 2008 and the end of 2010, intense seismic activity occurred in the area. This was manifested by several swarm-like sequences and continuous trickling seismicity over many days, amounting in total to more than 900 earthquakes in the magnitude range of 0.5 ≤ M d ≤ 5.2. The region of activity extended in a 40-km long zone mainly in a N-S direction and was located about 10 km west of the Roum fault. The largest earthquake, with a duration magnitude of M d = 5.2, occurred on February 15, 2008, and was located at 33.327° N, 35.406° E at a depth of 3 km. The mean-horizontal peak ground acceleration observed at two nearby accelerometers exceeded 0.05 g, where the strongest peak horizontal acceleration was 55 cm/s2 at about 20 km SE of the epicenter. Application of the HypoDD algorithm yielded a pronounced N-S zone, parallel to the Roum fault, which was not known to be seismically active. Focal mechanism, based on full waveform inversion and the directivity effect of the strongest earthquake, suggests left-lateral strike-slip NNW-SSE faulting that crosses the NE-SW traverse faults in southern Lebanon.

    atmospheric circulation with applications of the Lorenz model, explored the land-sea breeze problem with the Dynamics and Thermodynamics Circulation Model (DTDM), and developed simple radiative transfer models. Class projects explored the effects of varying the content of CO2 and CH4 in the atmosphere, as well as the properties of paleoclimates in atmospheric simulations using EdGCM. Initial assessment of student knowledge, attitudes, and behaviors associated with these activities, particularly about climate change, was measured. Pre- and post-course surveys provided student perspectives about the courses and their learning about remote sensing and climate change concepts. Student performance on the tutorials and course projects evaluated students' ability to learn and apply their knowledge about climate change and skills with remote sensing to assigned problems or proposed projects of their choice. Survey and performance data illustrated that the exercises were successful in meeting their intended learning objectives as well as opportunities for further refinement and expansion.

  9. Observations and exploration of a sequence of design environments: Students designing a series of multimedia projects

    NASA Astrophysics Data System (ADS)

    Viner, Mark

    The goal of this research study was to observe and describe changes that occurred in student and teacher skills, conceptual beliefs and actions as students designed a series of multimedia projects for authentic audiences. Furthermore, the research was designed to explore the scaffolding of events and actions of sequence of five design environments. In each environment, an instructor and his students worked toward creating integrated, collaborative curriculum projects. HyperStudio authoring software was used as a construction tool and publishing medium for student artifacts. Results of this study indicate that both teacher and students need to have an active role in the design process. Working as 'student designers' is a collaborative process that is both time-consuming and complex. Overall, both the teacher and his students were receptive to the process of design and felt it provided valuable benefits when compared to the traditional learning process. While this study did not address the issues of content knowledge acquisition or performances on standardized tests, it does provide some practical recommendations for teachers working with students in a design environment.

  11. Getting Students to Observe the Night Sky, Even When Your Sky is Cloudy Half the Time

    2010-01-01

    Teachers of introductory astronomy classes often wish to get our students to look at the night sky However, most educational institutions in America are located in regions where cloudy nights are relatively common. This paper describes a low cost way to integrate observations into a course which lacks a dedicated astronomy lab. Students in two large. general science classes in fall 2008 and spring 2009 were asked to participate in one of two global star-counting projects. The fall project was coordinated by UCAR and asked for observations of the constellation Cygnus (http://www.windows.ucar.edu/citizen_science/starcount/results.html). The spring project was run by Project Globe and asked for observations of the constellation Orion. (http://www.globe.gov/GaN/ ). In both cases, students simply find the constellation, match the star pattern to charts that go to different limiting magnitudes, and report the data to the coordinating organization. A copy of the report is sent to the course instructor. The instructor can ask for additional information. Did it work? The success of this project was evaluated by analyzing the e-mail messages that students returned in response to the assignment. In both courses, a very large majority of the students actually did the exercise and submitted a report. Students reported that observing the sky in this way was satisfying to them., and sometimes the reports were quite enthusiastic. In spring 2009, some preparatory activies were conducted during class that were designed to sensitize students to the beauty of the sky. Analysis of student reports indicated that these preparatory activities were helpful, but not as helpful as the instructor would like. This research is part of the Teacher Professional Continuum project at the University of Delaware, which is supported by the National Science Foundation.

    Astronomical Activities for students Motivating students interest in Physical Science through Astronomy Alexis Matthaiou Philekpaideftiki Etaireia, Arsakeio Lyceum Patron, Patras, Greece,(alexiosmat@yahoo.gr) School education aims not only to providing the necessary knowledge to the students but also to inspire and motivate them to realize their special abilities and inclinations and use their potential for making a joyful future for their lives. In this direction we present some activities held in the Arsakeio School of Patras during the years 2005-2008 in the field of Astronomy and Astrophysics, in order to share our experience with the teachers' community. Students from all grades of primary and secondary education participated with enthusiasm. In particular, they observed the Partial Solar Eclipse of October 3rd, 2005,and the Total Solar Eclipse of March 29th, 2006. They took part in observing and registering Solar Spots, using Astronomical equipments like different types of telescopes with filters and solar scopes. Students studied further the nature of Solar Phenomena and their effects on life, participating in the Environmental Program "Sun and Life"(2006-2007). Moreover, students took part in the International Program for measuring the Light Pollution "Globe at Night" (2006-2007) with observing and registering the luminosity of the Orion constellation in the night sky above their residence. Finally, the students participated in the European program "Hands on Universe" (HOU) (2005-2008) working on a project, which was the Greek contribution to HOU, developed from "Philekpaideftiki Etaireia". In particular, they studied the stars' spectrum and acquired information about the stars' life and age of stellar systems, using interactive multimedia technology.

  15. Teaching About Theory-Laden Observation to Secondary Students Through Manipulated Lab Inquiry Experience

    NASA Astrophysics Data System (ADS)

    Lau, Kwok-chi; Chan, Shi-lun

    2013-10-01

    This study seeks to develop and evaluate a modified lab inquiry approach to teaching about nature of science (NOS) to secondary students. Different from the extended, open-ended inquiry, this approach makes use of shorter lab inquiry activities in which one or several specific NOS aspects are manipulated deliberately so that students are compelled to experience and then reflect on these NOS aspects. In this study, to let students experience theory-laden observation, they were provided with different "theories" in order to bias their observations in the lab inquiry. Then, in the post-lab discussion, the teacher guided students to reflect on their own experience and explicitly taught about theory-ladenness. This study employs a quasi-experimental pretest-posttest design using the historical approach as the control group. The results show that the manipulated lab inquiry approach was much more effective than the historical approach in fostering students' theory-laden views, and it was even more effective when the two approaches were combined. Besides, the study also sought to examine the practical epistemological beliefs of students concerning theory-ladenness, but limited evidence could be found.

    Microvariability observations are presented for three objects - the BL Lac object OQ 530, the OVV quasar 3CR 345, and the very high redshift quasar PSS 1057+4555. All objects were observed using the 0.76m telescope at the Rosemary Hill Observatory. The object OQ 530 was observed in the R band during three nights in June of 1997. Observations in the V and I bands were made of the OVV quasar 3CR 345 in May of 2000. The microvariability behavior reported here for OQ 530 and 3CR 345 is compared to the previously reported behavior for these objects. In addition, observations were carried out over four nights in March and May of 2000 to search for microvariability of the very high redshift (z = 4.10) quasar PSS 1057+4555. The data presented here for these three objects are discussed in relation to current models for microvariability.

    2014-01-01

    Background Efforts are made to enhance in-class learner engagement because it stimulates and enhances learning. However, it is not easy to quantify learner engagement. This study aimed to develop and validate an observation tool for instructor and student behaviors to determine and compare in-class learner engagement levels in four different class types delivered by the same instructor. Methods Observer pairs observed instructor and student behaviors during lectures in large class (LLC, n=2) with third-year medical students, lectures in small class (LSC, n=6) and case-based teaching sessions (CBT, n=4) with fifth-year students, and problem-based learning (PBL) sessions (~7 hours) with second-year students. The observation tool was a revised form of STROBE, an instrument for recording behaviors of an instructor and four randomly selected students as snapshots for 5-min cycles. Instructor and student behaviors were scored 1–5 on this tool named ‘in-class engagement measure (IEM)’. The IEM scores were parallel to the degree of behavior's contribution to active student engagement, so higher scores were associated with more in-class learner engagement. Additionally, the number of questions asked by the instructor and students were recorded. A total of 203 5-min observations were performed (LLC 20, LSC 85, CBT 50, and PBL 48). Results Interobserver agreement on instructor and student behaviors was 93.7% (κ=0.87) and 80.6% (κ=0.71), respectively. Higher median IEM scores were found in student-centered and problem-oriented methods such as CBT and PBL. A moderate correlation was found between instructor and student behaviors (r=0.689). Conclusions This study provides some evidence for validity of the IEM scores as a measure of student engagement in different class types. PMID:25308966

    The High-resolution Coronal Imager (Hi-C) has provided Fe XII 193A images of the upper transition region moss at an unprecedented spatial ({approx}0.''3-0.''4) and temporal (5.5 s) resolution. The Hi-C observations show in some moss regions variability on timescales down to {approx}15 s, significantly shorter than the minute-scale variability typically found in previous observations of moss, therefore challenging the conclusion of moss being heated in a mostly steady manner. These rapid variability moss regions are located at the footpoints of bright hot coronal loops observed by the Solar Dynamics Observatory/Atmospheric Imaging Assembly in the 94 A channel, and by the Hinode/X-Ray Telescope. The configuration of these loops is highly dynamic, and suggestive of slipping reconnection. We interpret these events as signatures of heating events associated with reconnection occurring in the overlying hot coronal loops, i.e., coronal nanoflares. We estimate the order of magnitude of the energy in these events to be of at least a few 10{sup 23} erg, also supporting the nanoflare scenario. These Hi-C observations suggest that future observations at comparable high spatial and temporal resolution, with more extensive temperature coverage, are required to determine the exact characteristics of the heating mechanism(s).

    2016-04-01

    We investigate periodicities in the mean heliographic latitudes of sunspot groups, called active latitudes, for the past six complete solar cycles (1945 - 2008). For this purpose, the multitaper method and Morlet wavelet analysis were used. We found that solar rotation periodicities (26 - 38 days) are present in active latitudes of both hemispheres for all the investigated cycles (18 to 23). Both in the northern and southern hemispheres, active latitudes drifted toward the equator from the beginning to the end of each cycle and followed an oscillating path. These motions are well described by a second-order polynomial. There are no meaningful periods of between 55 and about 300 days in either hemisphere for all cycles. A periodicity of 300 to 370 days appears in both hemispheres for Cycle 23, in the northern hemisphere for Cycle 20, and in the southern hemisphere for Cycle 18.

    (Abstract only) We have innovatively designed and constructed three observatories each costing a few hundred USD for housing three small Schmidt-Cassegrain type telescopes namely, Celestron CGE925, Celestron CGE1400, Meade 12-inch LX200GPS. These observatories are completely different in design and are found to be perfectly usable for doing serious work on astronomical observation and measurements. The observatory with the Celestron CGE1400 telescope has been inducted, since January 2012, as one of the observatories of the international “Orion Project” headquartered at Phoenix, Arizona, which is dedicated for photometric and spectroscopic observations of five bright variable stars of the Orion constellation namely, Betelgeuse (alpha Ori), Rigel (beta Ori), Mintaka (delta Ori), Alnilam (epsilon Ori) and Alnitak (zeta Ori). Using this observatory, we have been producing BVRI photometric data for the five stars of the Orion project. The other observatory with the Meade 12-inch LX200GPS telescope is being inducted into service for CCD photometric study of SU UMa stars in connection with implementation of a project funded by Indian Space Research Organization (ISRO). In the present paper, we would like to describe our self-built observatories, our observational facilities, the BVRI photometric data that we acquired for the Orion project, and our future plan for observation of variable stars of interest.

    1996-01-01

    Peer models (classmates without disabilities) who were proficient in performing a task completed one response chain each day and described the steps they performed while their classmates with disabilities observed. Three students with disabilities participated, and their performance of the response chains was assessed immediately prior to and following the peer modeling each day. A multiple probe design across response chains, replicated across children with disabilities, was used. In addition, participation and social interactions of children with disabilities and their peer models were assessed in classroom activities after daily modeling sessions. The results indicate that the peer models performed the response chains accurately and quickly, and students with disabilities acquired the response chains. Across the study, participation in classroom activities was high, social interactions were low, and neither was affected by the peer modeling intervention. PMID:8881344

    2015-12-01

    The purpose of the present article is to describe three simple practical experiments that aim to observe and discuss the anatomic and physiological functions and differences between arteries and veins as well as the alterations observed in skin blood flow in different situations. For this activity, students were divided in small groups. In each group, a volunteer is recruited for each experiment. The experiments only require a sphygmomanometer, rubber bands, and a clock and allow students to develop a hypothesis to explain the different responses to the interruption of arterial and venous blood flow. At the end, students prepare a short report, and the results are discussed. This activity allows students to perceive the presence of physiology in their daily lives and helps them to understand the concepts related to the cardiovascular system and hemodynamics.

    This study evaluated the classroom measure of active engagement (CMAE), an observational tool designed to measure active engagement in students with autism spectrum disorder (ASD). Participants included 196 students with ASD and their educators (n = 126) who were video-recorded at the beginning of the school year. Findings documented limited active engagement overall, with students spending less than half of the observation well-regulated, productive, or independent and infrequently directing eye gaze and communicating. Confirmatory factor analysis indicated that the structure of the CMAE was represented by a 5-factor model. These findings underscore the need for improved active engagement in students with ASD and show promise for a tool to measure behaviors associated with positive educational outcomes in students with ASD.

    2012-02-01

    This paper presents an analysis of records obtained by video equipment of the 2001 Leonid meteor storm. Totally, 3712 meteors, including 22 non-Leonid ones, were recognized from the record of 247 min. The brightness of meteors was measured with the software ``LIMovie'', and a population index of r = 2.01 ± 0.05 (-8 ≤ mag ≤ -3) was thus derived. We proposed a way to derive the mass-distribution index, s = 1.82, from only our one-station data. The maximum of the activity appeared at 18h25m UT with an effective peak of ZHR90°×67° = 52606 (mag ≤ +6.5). There are also compatible sub-peaks and high plateaus beside the main peak. One of them may correspond to the predicted 9-revolution dust trail (ejection in 1699). In this article we treat the cross section of the influx zone as a trapezoid. The peak ``influx rate'' generated by the 4-revolution dust trail (ejection in 1866) thus derived would be 6.76 × 10-5km-2s-1 (mag ≤ +6.5), and the corresponding ``spatial number density'' would be 9.52 × 10-7km-3 (mag ≤ +6.5).

The north polar region of the Sun had near-zero field strength for more than three years (2012-2015) and ended only in September 2015 as indicated by the presence of polar PEs and the lack of MBE. The zero-polar-field condition in the south started only around 2013, but it ended by June 2014. Thus the asymmetry in the times of polarity reversal switched between cycle 23 and 24. The polar MBE is a good proxy for the polar magnetic field strength as indicated by the high degree of correlation between the two. The cross-correlation between the high- and low-latitude MBEs is significant for a lag of approximately 5.5 to 7.3 years, suggesting that the polar field of one cycle indicates the sunspot number of the next cycle in agreement with the Babcock-Leighton mechanism of solar cycles. The extended period of near-zero field in the north-polar region should result in a weak and delayed sunspot activity in the northern hemisphere in cycle 25.

  13. Cassini UVIS Observations Show Active Saturn's Rings

    NASA Astrophysics Data System (ADS)

    Esposito, L.; Colwell, J. E.; UVIS Team

    2004-12-01

    The Cassini Ultraviolet Imaging Spectrograph (UVIS) is part of the remote sensing payload of the NASA/ESA Cassini spacecraft. This spectrograph includes channels for extreme UV and far UV spectroscopic imaging, high speed photometry of stellar occultations, solar EUV occultation, and a hydrogen/deuterium absorption cell. We report our initial results from UVIS observations of Saturn's rings. Dynamic interactions between neutrals, ions, rings, moons and meteoroids produce a highly structured and time variable Saturn system Oxygen in the Saturn system dominates the magnetosphere. Observed fluctuations indicate close interactions with plasma sources. Stochastic events in the E ring may be the ultimate source. The spectral signature of water ice is seen on Phoebe and in Saturn's rings. Water ice is mixed non-uniformly with darker constituents. The high structure of the UV ring reflectance argues that collisional transport dominates ballistic transport in darkening the rings. Our preliminary results support the idea that rings are recycled fragments of moons: the current processes are more important than history and initial conditions. The spectra along the UVIS SOI radial scan indicate varying amounts of water ice. In the A ring, the ice fraction increases outward to a maximum at the outer edge. This large-scale variation is consistent with initially pure ice that has suffered meteoritic bombardment over the age of the Solar system (Cuzzi and Estrada 1998). We also see variations over scales of 1000 - 3000 km, which cannot be explained by this mechanism. Ballistic transport of spectrally neutral extrinsic pollutants from meteoroids striking the rings has a typical throw distance of 6000 km (Durisen et al 1989), too long to explain this finer structure. We propose a class of smaller renewal events, in which a small moon residing within the rings is shattered by an external impactor (Colwell and Esposito 1993, Barbara and Esposito 2002, Esposito and Colwell 2003).

  1. Science Teaching and Learning Activities and Students' Engagement in Science

    NASA Astrophysics Data System (ADS)

    Hampden-Thompson, Gillian; Bennett, Judith

    2013-06-01

    The purpose of this analysis is to describe the variation in students' reports of engagement in science across science teaching and learning activities. In addition, this study examines student and school characteristics that may be associated with students' levels of engagement in science. Data are drawn from the Programme for International Student Assessment 2006 study. The analysis employs a quantitative approach that includes descriptive and inferential statistics to examine three measures of student engagement for a nationally representative sample of approximately 12,000 15-year-old students in the UK. The main results indicate that there is an association between students' motivation towards science, enjoyment of science and future orientation towards science, and the frequency in which various teaching and learning activities take place in the classroom. Understanding student engagement in science and the factors that influence it is essential in addressing the issue of uptake of science after compulsory schooling.

    NASA Astrophysics Data System (ADS)

    Mikael Hamza, Karim; Wickman, Per-Olof

    2013-09-01

    The purpose of this study is to use a comparative approach to scrutinize the common assumption that certain school science activities are theoretical and therefore particularly suited for engaging students with scientific ideas, whereas others are practical and, thus, not equally conducive to engagement with scientific ideas. We compared two school science activities, one (laboratory work) that is commonly regarded as focusing attention on artefacts that may distract students from central science concepts and the other (concept mapping) that is thought to make students focus directly on these concepts. We observed students in either a laboratory activity about real galvanic cells or a concept-mapping activity about idealized galvanic cells. We used a practical epistemology analysis to compare the two activities regarding students' actions towards scientific ideas and artefacts. The comparison revealed that the two activities, despite their alleged differences along the theory-practice scale, primarily resulted in similar student actions. For instance, in both activities, students interacted extensively with artefacts and, to a lesser extent, with scientific ideas. However, only occasionally did students establish any explicit continuity between artefacts and scientific ideas. The findings indicate that some of the problems commonly considered to be unique for school science practical work may indeed be a feature of school science activities more generally.

    2015-05-01

    This study aims to explore the implementation of the Indonesian Realistic Mathematics Education (PMRI) in Aceh primary schools, Indonesia. This study investigates the students' mathematics activities involved in the implementation of PMRI and for this purpose; students' mathematics activities in the classroom were observed. Students were observed three times within five weeks during mathematics class, based on PMRI. A total of 25 year five students from a public school participated in this study. Observation check list was used in this study based on ten items. The observation conducted was based on two different time periods which were 105 minutes for group A and 70 minutes for group B. The observation was conducted every 5 minutes. The results show that PMRI is being practised in Aceh, but not completely. This study shows that mathematics activities for those who were taught using PMRI are higher than for those using the traditional approach. Overall, the findings showed that the number of student activities undertaken in PMRI achieved 90.56%. The higher percentage of activities suggests that the Aceh Education Office expands the implementation of PMRI in all primary schools so that learning of mathematics is more effective. This indirectly increases the mathematics achievement of students in Aceh to a higher level on par with Indonesia's national achievement.

  5. Students' Learning Activities While Studying Biological Process Diagrams

    NASA Astrophysics Data System (ADS)

    Kragten, Marco; Admiraal, Wilfried; Rijlaarsdam, Gert

    2015-08-01

    Process diagrams describe how a system functions (e.g. photosynthesis) and are an important type of representation in Biology education. In the present study, we examined students' learning activities while studying process diagrams, related to their resulting comprehension of these diagrams. Each student completed three learning tasks. Verbal data and eye-tracking data were collected as indications of students' learning activities. For the verbal data, we applied a fine-grained coding scheme to optimally describe students' learning activities. For the eye-tracking data, we used fixation time and transitions between areas of interest in the process diagrams as indices of learning activities. Various learning activities while studying process diagrams were found that distinguished between more and less successful students. Results showed that between-student variance in comprehension score was highly predicted by meaning making of the process arrows (80%) and fixation time in the main area (65%). Students employed successful learning activities consistently across learning tasks. Furthermore, compared to unsuccessful students, successful students used a more coherent approach of interrelated learning activities for comprehending process diagrams.

    Over the past several years the NASA E/PO Group at Sonoma State University has operated a small robotic telescope in northern Sonoma County, California. The telescope is used by high school and college instructors and their students from around the United States. Observations have been used both in classroom settings and in after-school or extracurricular activities. It has also been central over the past two summers (2009/2010) as part of a summer science internship program for Sonoma County high school students. The program gave these students an in-depth experience collecting and analyzing astronomical data. This poster describes some of the ways that the telescope has been used to make scientific measurements (as opposed to “pretty pictures”) of astronomical phenomena in high school settings. Some of the obstacles to implementing a set of astronomical observations in the high school classroom will be described, as will the steps we have taken to overcome them. Information is provided on how instructors can become involved in using the telescope and what support is available to help them get started in their classes.

  10. Simple Activities to Improve Students' Understanding of Microscopic Friction

    NASA Astrophysics Data System (ADS)

    Corpuz, Edgar de Guzman; Rebello, N. Sanjay

    2012-05-01

    We are currently on the verge of several breakthroughs in nanoscience and technology, and we need to prepare our citizenry to be scientifically literate about the microscopic world. Previous research shows that students' mental models of friction at the atomic level are significantly influenced by their macroscopic ideas. Most students see friction at the microscopic scale as due to the meshing of bumps and valleys and rubbing of atoms. Furthermore, for most students, what is true macroscopically should also be true microscopically. Friction provides a very good context for making students aware of the disparity between the macroscopic and microscopic worlds. In the proceeding sections we will present a series of activities that teachers can use to refine students' ideas of friction at the microscopic level. Several teaching interviews2 were conducted to develop and validate these activities and to establish the concepts/ideas that students adopt as they go through each of the activities.

  17. Empowering Students in Science through Active Learning: Voices From Inside the Classroom

    NASA Astrophysics Data System (ADS)

    Erickson, Sabrina Ann

    Preparing students for success in the 21st century has shifted the focus of science education from acquiring information and knowledge to mastery of critical thinking and problem-solving skills. The purpose of this qualitative case study was to examine teacher and student perspectives of the relationship between (a) active learning, problem solving, and achievement in science and (b) the conditions that help facilitate this environment. Adapting a social constructivist theoretical framework, high school science teachers and students were interviewed, school records analyzed, curriculum documents studied, and classes observed. The findings revealed that students were engaged with the material in an active learning environment, which led to a sense of involvement, interest, and meaningful learning. Students felt empowered to take ownership of their learning, developed the critical thinking skills necessary to solve problems independently and became aware of how they learn best, which students reported as interactive learning. Moreover, student reflections revealed that an active environment contributed to deeper understanding and higher skills through interaction and discussion, including questioning, explaining, arguing, and contemplating scientific concepts with their peers. Recommendations are for science teachers to provide opportunities for students to work actively, collaborate in groups, and discuss their ideas to develop the necessary skills for achievement and for administrators to facilitate the conditions needed for active learning to occur.

  19. Social competence and collaborative guided inquiry science activities: Experiences of students with learning disabilities

    NASA Astrophysics Data System (ADS)

    Taylor, Jennifer Anne

    This thesis presents a qualitative investigation of the effects of social competence on the participation of students with learning disabilities (LD) in the science learning processes associated with collaborative, guided inquiry learning. An inclusive Grade 2 classroom provided the setting for the study. Detailed classroom observations were the primary source of data. In addition, the researcher conducted two interviews with the teacher, and collected samples of students' written work. The purpose of the research was to investigate: (a) How do teachers and peers mediate the participation of students with LD in collaborative, guided inquiry science activities, (b) What learning processes do students with LD participate in during collaborative, guided inquiry science activities, and (c) What components of social competence support and constrain the participation of students with LD during collaborative, guided inquiry science activities? The findings of the study suggest five key ideas for research and teaching in collaborative, guided inquiry science in inclusive classrooms. First, using a variety of collaborative learning formats (whole-class, small-group, and pairs) creates more opportunities for the successful participation of diverse students with LD. Second, creating an inclusive community where students feel accepted and valued may enhance the academic and social success of students with LD. Third, careful selection of partners for students with LD is important for a positive learning experience. Students with LD should be partnered with academically successful, socially competent peers; also, this study suggested that students with LD experience more success working collaboratively in pairs rather than in small groups. Fourth, a variety of strategies are needed to promote active participation and positive social interactions for students with and without LD during collaborative, guided inquiry learning. Fifth, adopting a general approach to teaching

    2016-07-01

    Effective engagement of nursing students in the study of biosciences remains a challenge for many tertiary institutes. In this study we attempted to implement and then evaluate a simple hands-on intervention, consisting of a series of hands-on games and puzzles, to increase nursing student engagement with core concepts and anatomical learning involved in clinical anatomy and physiology. The study used a quazi-experimental longitudinal before and after design, to explore the effect of a learning intervention on student performance. Set across three different campuses of the same University, it included 1320 first year undergraduate nursing students from 2013 to 2014 who were studying Anatomy and Physiology. Students were exposed to the interventions or not, and concomitant academic performance, weekly quiz scores, performance in fortnightly worksheets and, across the semester, exam performance were compared. The results show that while the intervention appeared to increase academic performance in students on one campus (2013) compared to the other two, this difference was not sustained into 2014 when a bigger cohort was examined. Despite significant subjective student satisfaction and enthusiasm about these learning and teaching interventions, the data does not support the capacity of these activities to enhance student academic performance. Tertiary entrance scores, being a non-native English speakers and socio-economic status all had a bigger impact on student performance than engagement with fun anatomy and physiology activities.

    2014-07-01

    Academic results depend strongly on the individual circumstances of students: background, motivation and aptitude. We think that academic activities conducted to increase motivation must be tuned to the special situation of the students. Main goal of this work is analyze the students in the first year of the Degree in Optics and Optometry in the University of Granada and the suitability of an activity designed for those students. Initial data were obtained from a survey inquiring about the reasons to choose this degree, their knowledge of it, and previous academic backgrounds. Results show that: 1) the group is quite heterogeneous, since students have very different background. 2) Reasons to choose the Degree in Optics and Optometry are also very different, and in many cases were selected as a second option. 3) Knowledge and motivations about the Degree are in general quite low. Trying to increase the motivation of the students we designed an academic activity in which we show different topics studied in the Degree. Results show that students that have been involved in this activity are the most motivated and most satisfied with their election of the degree.

    PubMed

    Cummings, Cynthia L; Connelly, Linda K

    2016-01-01

    In 2014, nursing faculty conducted a study with undergraduate nursing students on their satisfaction, confidence, and educational practice levels, as it related to simulation activities throughout the curriculum. The study was a voluntary survey conducted on junior and senior year nursing students. It consisted of 30 items based on the Student Satisfaction and Self-Confidence in Learning and the Educational Practices Questionnaire (Jeffries, 2012). Mean averages were obtained for each of the 30 items from both groups and were compared using T scores for unpaired means. The results showed that 8 of the items had a 95% confidence level and when combined the items were significant for p <.001. The items identified were those related to self-confidence and active learning. Based on these findings, it can be assumed that repeated simulation experiences can lead to an increase in student confidence and active learning. PMID:26599594

    This reports a history and future prospects of the activities by the Student Forum of the Geoinformation Forum Japan. For growths of academic fields, active communications among students and young scientists are indispensable. Several academic communities in geoinformation fields are established by youths and play important roles of building networks over schools and institutes. The networks are expected to be innovative cooperation after the youths achieve their professions. Although academic communities are getting fixed growth particularly in Japan, youths had gotten little opportunities to make contacts with youths themselves. To promote gotten youth activities among geoinformation fields, in 1998, we started a series of programs that named the Student Forum of the Geoinformation Forum Japan involving students and young scientists within the annual conferences, Geoinformation Forum Japan. The programs have provided opportunities to do presentation their studies by posters, some events, and motivations to create networks among students and young scientists. From 2009, some members of our activities set additional conference in west area of Japan. Thus our activities are spread within Japan. As a result of these achievements, the number of youth dedicating to the programs keeps growing. From 2009, it's getting international gradually, however, almost all the participants are still Japanese. To keep and expand the network, we are planning to make some nodes with some Asian youth organizations in the field of geoinformation. This paper is concluded with proposals and future prospects on the Student Forum of the Geoinformation Forum Japan.

    ground truth data for CERES the 3 satellites currently carrying those instruments provide several options for scheduling. Should the citizen scientist be of school age, the student will be able to take the skills learned with the S'COOL project from the backyard to the classroom - or vice versa. S'COOL has attracted some unique citizen scientists over the years, providing ground truth observations from several unique locations. These include a group that circumnavigated the American continents, a woman who has rowed solo across all the world's oceans, and planned participation this fall from several Pacific research cruises. Classroom students turn ROVER observers, or citizen scientists that observe from varying locations, help over summer breaks and vacations. This is the case with a dedicated Connecticut elementary classroom that observes clouds as a class and is assigned summer work as roving observers to continue the data collection over their break. Outcomes: This paper will summarize the S'COOL project's experience with a variety of citizen scientists over the course of activities to date.

  10. Reflections and unprompted observations by healthcare students of an interprofessional shadowing visit.

    PubMed

    Wright, Anna; Hawkes, Gillian; Baker, Becky; Lindqvist, Susanne Marie

    2012-07-01

    This paper reports work from a Centre for Interprofessional Practice in a higher education institution in the UK that offers four levels of interprofessional learning (IPL) to all healthcare students. The second level (IPL2) integrates professional practice into the learning process, requiring students to shadow a qualified healthcare professional (from a different profession) for half a day. Students complete a reflective statement upon their learning experience on their return. A study was undertaken to analyse students' reflective statements in depth to see their observations and reflections on the shadowing visit. Using frame analysis, 160 reflective statements were analyzed, identifying common words and phrases used by students, which were then grouped together under six themes. Three of these related directly to the assignment: communication styles and techniques; communication between healthcare professionals and comparison of students' own and other healthcare professionals' roles. Three themes emerged from student's own interpretation of observations and reflections made during the shadowing of a different professional: attitudes toward other professions; power structures between professionals and patients and between professionals and impact of communication on patient care. Interprofessional shadowing gives students an opportunity to observe communication between healthcare professionals and patients and to reflect on broader issues surrounding collaborative working.

    Physical activity is associated with health. The aim of this study was (a) to access if Portuguese university students meet the public health recommendations for physical activity and (b) the effect of gender and day of the week on daily PA levels of university students. This observational cross-sectional study involved 126 (73 women) healthy Portuguese university students aged 18–23 years old. Participants wore the ActiGraph wGT3X-BT accelerometer for seven consecutive days. Number of steps, time spent sedentary and in light, moderate and vigorous physical activity were recorded. The two-way MANOVA revealed that gender (p-value = 0.001; η2 = 0.038; minimum effect) and day of the week (p-value = 0.001; η2 = 0.174; minimum effect) had significant main effects on the physical activity variables. It was shown that during weekdays, male students walked more steps (65.14%), spent less time sedentary (6.77%) and in light activities (3.11%) and spent more time in moderate (136.67%) and vigorous activity (171.29%) in comparison with weekend days (p < 0.05). The descriptive analysis revealed that female students walked more steps (51.18%) and spent more time in moderate (125.70%) and vigorous (124.16%) activities during weekdays than in weekend days (p < 0.05). Women students did not achieve the recommended 10,000 steps/day on average during weekdays and weekend days. Only male students achieved this recommendation during weekdays. In summary, this study showed a high incidence of sedentary time in university students, mainly on weekend days. New strategies must be adopted to promote physical activity in this population, focusing on the change of sedentary behaviour. PMID:27022993

  12. Galileo SSI Observations of Volcanic Activity at Tvashtar Catena, Io

    Introduction: We report on the analysis of the Galileo SSI's observations of the volcanic activity at Tvashtar Catena, Io as discussed by Milazzo et al. Galileo's Solid State Imager (SSI) observed Tvashtar Catena (63 deg N, 120 deg W) four times between November 1999 and October 2001, providing a unique look at the distinctive high latitude volcanism on Io. The November 1999 observation spatially resolved, for the first time, an active extraterrestrial fissure eruption. The brightness temperature of the lavas at the November 1999 fissure eruption was 1300 K. The second observation (orbit I27, February 2000) showed a large (approx. 500 sq km) region with many, small spots of hot, active lava. The third observation was taken in conjunction with a Cassini observation in December 2000 and showed a Pele-like plume deposition ring, while the Cassini images revealed a 400 km high Pele-type plume above the Catena. The final Galileo SSI observation of Tvashtar was acquired in October 2001, and all obvious (to SSI) activity had ceased, although data from Galileo's Near Infrared Mapping Spectrometer (NIMS) indicated that there was still significant thermal emission from the Tvashtar region. We have concentrated on analyzing the style of eruption during orbit I27 (February 2000). Comparison with a lava flow cooling model indicates that the behavior of the Tvashtar eruption during I27 does not match that of "simple" advancing lava flows. Instead, it may be an active lava lake or a complex set of lava flows with episodic, overlapping (in time and space) eruptions.

    The High Resolution Imaging Science Experiment (HiRISE) onboard Mars Reconnaissance Orbiter (MRO) has been used to monitor the seasonal evolution of several regions at high southern latitudes and, in particular, the geyser-like activity which may result from the process described by Kieffer [JGR, 112, 8005, 2007] involving translucent CO2 ice. Here, we mostly concentrate on observations of the Inca City (81S, 296E) region. The observations indicate rapid on-set of activity at the beginning of southern spring with activity initiating before HiRISE can obtain adequately illuminated images (Ls < 174 at Inca City). Most sources became active within the subsequent 8 weeks. Activity is indicated by the production of dark deposits surrounded by brighter bluer deposits which probably arise from the freezing out of vented CO2 [Titus et al., AGU Abstract P41A-0188, 2007]. These deposits originate from araneiform structures (spiders), stones on ridges, cracks on slopes, and along linear cracks in the slab ice on flatter surfaces. The type of activity observed can often be explained qualitatively by considering the local topography. Some dark fans were observed to shorten enormously in length on a timescale of 18 days. We consider this to be strong evidence that emission was in progress at the time of HiRISE image acquisition. The orientations of surficial deposits were mostly topographically controlled in Inca City in 2007. The deposition of dark material also appeared to be influenced by local topography suggesting that the ejection from the vents was at low velocity (<10 m/s) and that a ground-hugging flow type process (a sort of "cryo-fumarole") may have been occurring. The presentation will illustrate the above features and make a first comparison between activity separated by one full Martian year. Our first observations indicate a stronger influence of wind in 2009.

    2016-01-01

    The present study investigated the guidance provided by science teachers to resolve conflicts during socioscientific issue-based argumentation activities. A graphical representation (GR) was developed as a tool to code and analyze the dialogue interaction process. Through the GR and qualitative analysis, we identified three types of dialogue reconciling strategies. The first one consists of teacher management, in which the teacher temporarily maintains the right to speak when students get mired in an emotional rebuttal situation. The second strategy involves the use of qualifiers to identify the strengths and weaknesses of an opposing argument. The third strategy consists of providing students with guidance to keep both parties (i.e. the students taking, respectively, the affirmative and negative positions) on the same discussion topic and can be used to assist teachers with forming broad questions that prompt students to conduct deeper discussions. These reconciling strategies were beneficial in that they helped students to argue in a more reflective way.

    Optics and photonics research in Africa has gradually grown in the past ten years with a very active optical community involved in state-of-the-art research. Despite relatively low resources, optics research in the continent is competitive with many international benchmarks and has had a significant impact within the African continent. In the past five years, a group of dynamic students have developed the student chapter network from Tunisia to South Africa. The first student chapters of the optical society of America (OSA) and the international society for optics and photonics (SPIE) were established in South Africa (in the Council for Scientific and Industrial Research (CSIR) and in the University of Stellenbosch), followed by a chapter in Tunisia (Engineering school of communications of Tunis, Sup'Com). In this paper, we will present the major activities of the student chapters of Tunisia and South Africa, and how they are promoting optics and photonics in Africa.

  16. Radio Imaging Observations of Solar Activity Cycle and Its Anomaly

    NASA Astrophysics Data System (ADS)

    Shibasaki, K.

    2011-12-01

    The 24th solar activity cycle has started and relative sunspot numbers are increasing. However, their rate of increase is rather slow compared to previous cycles. Active region sizes are small, lifetime is short, and big (X-class) flares are rare so far. We study this anomalous situation using data from Nobeyama Radioheliograph (NoRH). Radio imaging observations have been done by NoRH since 1992. Nearly 20 years of daily radio images of the Sun at 17 GHz are used to synthesize a radio butterfly diagram. Due to stable operation of the instrument and a robust calibration method, uniform datasets are available covering the whole period of observation. The radio butterfly diagram shows bright features corresponding to active region belts and their migration toward low latitude as the solar cycle progresses. In the present solar activity cycle (24), increase of radio brightness is delayed and slow. There are also bright features around both poles (polar brightening). Their brightness show solar cycle dependence but peaks around solar minimum. Comparison between the last minimum and the previous one shows decrease of its brightness. This corresponds to weakening of polar magnetic field activity between them. In the northern pole, polar brightening is already weakened in 2011, which means it is close to solar maximum in the northern hemisphere. Southern pole does not show such feature yet. Slow rise of activity in active region belt, weakening of polar activity during the minimum, and large north-south asymmetry in polar activity imply that global solar activity and its synchronization are weakening.

    After a successful exit from hibernation, Rosetta started observing its final target comet 67P in March 2014 with the two OSIRIS cameras WAC and NAC (Wide Angle and Narrow Angle Camera) [1]. By the time of this conference, the spacecraft will have flown from 5 million to 50 km from the nucleus surface, reaching a resolution of 1 meter/pixel in the NAC images. During that period, the comet heliocentric distance varies from 4.3 to 3.2 AU and we will observe how the early activity develops. We know that cometary surfaces are not fully active; only a small fraction of the surface emits gas and dust. However we do not yet understand why it happens in that way, and what to expect on 67P. Recent publications using data from ground-based telescopes have proposed different interpretations for the distribution of active sources, from one to three at various latitudes [2, 3]. There is some evidence for different levels of activity in the northern and southern hemispheres, but these variations can only be constrained with close range data. In August 2014, OSIRIS will map the surface of the comet at high resolution, and perform weekly monitoring of the activity, especially the faintest jets. With these images and the inversion code COSSIM [4], we will be able to link observed features in the coma or on the limb to physical spots on the surface. On other comets visited by spacecrafts the activity has sometimes been associated with smooth areas, rough terrains, or specific morphologic features (cliff, crater, rim, . . . ). We will present a first look at how activity and terrain are linked on 67P, and look at variations of composition, morphology, or both. We will compare this identification of active areas to previous publications.

    Superflares are large explosive events on stellar surfaces one to six orders-of-magnitude larger than the largest flares observed on the Sun throughout the space age. Due to the huge amount of energy released in these superflares, it has been speculated if the underlying mechanism is the same as for solar flares, which are caused by magnetic reconnection in the solar corona. Here, we analyse observations made with the LAMOST telescope of 5,648 solar-like stars, including 48 superflare stars. These observations show that superflare stars are generally characterized by larger chromospheric emissions than other stars, including the Sun. However, superflare stars with activity levels lower than, or comparable to, the Sun do exist, suggesting that solar flares and superflares most likely share the same origin. The very large ensemble of solar-like stars included in this study enables detailed and robust estimates of the relation between chromospheric activity and the occurrence of superflares.

    Hackney, Marcella Wichser

    1999-10-01

    This research explored development of analogical thought through high school biology students' participation in a year-long sequence of analogical activities. Analogizing involves: selecting a familiar analog; mapping similarities and differences between the analog and less familiar target; making inferences from the analogy; evaluating validity of the inferences; and ultimately, understanding the biological target (Holyoak & Thagard, 1995). This investigation considered: student development of independence in learning through analogical thought, student learning of biology, the relationship between development of students' analogical thinking and students' learning of biology, and the quality of student interactions in the classroom This researcher, as teacher participant, used three approaches for teaching by analogy: traditional didactic, teacher-guided, and analogy-generated-by-the-student (Zeitoun, 1983). Within cooperative groups, students in one honors biology class actively engaged in research-based analogical activities that targeted specific biological topics. Two honors biology classes participated in similar, but nonanalogical activities that targeted the same biological topics. This two-class comparison group permitted analytical separation of effects of the analogical emphasis from the effects of biology content and activity-based learning. Data collected included: fieldnotes of researcher observations, student responses to guidesheets, tapes of group interactions, student products, student perceptions survey evaluations, ratings of students' expressed analogical development, pre- and posttest scores on a biology achievement test, essay responses, and selected student interviews. These data formed the basis for researcher qualitative analysis, augmented by quantitative techniques. Through participation in the sequence of analogical activities, students developed their abilities to engage in the processes of analogical thinking, but attained different

    Introduction Primary features of observational public health surveillance instruments are that they are valid, can reliably estimate physical activity behaviors, and are useful across diverse geographic settings and seasons by different users. Previous studies have reported the validity and reliability of Systematic Observation of Play and Recreation in Communities (SOPARC) to estimate park and user characteristics. The purpose of this investigation was to establish the use of SOPARC as a surveillance instrument and to situate the findings from the study in the context of the previous literature. Methods We collected data by using SOPARC for more than 3 years in 4 locations: Philadelphia, Pennsylvania; Columbus, Ohio; Chapel Hill/Durham, North Carolina; and Albuquerque, New Mexico during spring, summer, and autumn. Results We observed a total of 35,990 park users with an overall observer reliability of 94% (range, 85%–99%) conducted on 15% of the observations. We monitored the proportion of park users engaging in moderate-to-vigorous physical activity (MVPA) and found marginal differences in MVPA by both city and season. Park users visited parks significantly more on weekend days than weekdays and visitation rates tended to be lower during summer than spring. Conclusion SOPARC is a highly reliable observation instrument that can be used to collect data across diverse geographic settings and seasons by different users and has potential as a surveillance system.

    Scientists are very interested in the formation of contrails, both the type and the coverage. To be detected by a satellite-born instrument, the contrail must be of a certain size, which means that some contrails go undetected. The K-12 education community is assisting with the study of contrails by participating in a network of student observers. To provide a venue for student contrail observations, the GLOBE Contrails protocol was developed as part of the GLOBE Atmospheric Science protocols. The first year of observations has provided a rich resource for researcher.

  8. NIMS Observes Increased Activity at Loki Patera, Io

    NASA Technical Reports Server (NTRS)

    1997-01-01

    Loki Patera, historically the most active and persistent hot spot on Io, is located on the hemisphere of Io always facing Jupiter. Loki Patera was the site of two plumes during the Voyager encounters, which were not seen during the early orbits of Galileo. Ground-based observers reported Loki Patera to be unusually dim during this time, marking a period of low volcanic activity.

    On 21 February 1997, during Galileo's sixth orbit, the Near Infrared Mapping Spectrometer (NIMS) on the Galileo spacecraft observed Io in daylight from a range of approximately 703,000 km (440,000 miles). The image on the left shows Io at a wavelength of 2.95 microns. Loki Patera is seen to be relatively quiescent (at longer wavelengths which are more sensitive to thermal emission, Loki Patera is more noticeable).

    A few weeks later, on March 12th 1997, ground based observers using the Infra-Red Telescope Facility (IRTF) on Mauna Kea, Hawaii, observed an intense brightening in the Loki region, so much that Loki was contributing 75% of Io's in-eclipse flux for this hemisphere. A large eruption was taking place! Other ground-based observations through March, April and May tracked the course of the activity and confirmed its location at Loki Patera.

    On 4 April 1997, NIMS again observed Io during the seventh orbit from a range of 556,000 km (348,000 miles), with Loki Patera positioned in darkness, close to the limb. The image on the right shows the increase in activity at Loki Patera, again at 2.95 microns. A preliminary single temperature fit to NIMS orbit seven Loki Patera hot spot data yields a temperature of 500 K and an area of over 800 square kilometers. That the image is so bright at this wavelength is an indication of the areal extent of the activity. It is also probable that some part of the volcanic material being erupted or exposed is at considerably higher temperatures than that of the 500 K single-temperature fit.

  9. 19th century auroral observations reveal solar activity patterns

    NASA Astrophysics Data System (ADS)

    Silverman, Sam

    Growing interest in the aurora in the early part of the eighteenth century, which resulted from the spectacular reappearance of the aurora in 1707 and 1716, followed a relative scarcity of great auroras during the Maunder minimum, a period of prolonged reduced solar activity from about 1645-1715. Observations in the early eighteenth century led to questions about the geographical extent, nature, and temporal variability of the auroras. Typically, such observations were included as part of recorded meteorological notations, though occasionally early astronomers, such as Tycho Brahe in the 1590s, included auroras in their observations. Meteorological observations were important because of the effects of weather and climate on agriculture, and, according to the belief at the time, on disease.

  10. Some implications of ultraviolet observations of quasars and active galaxies

    The problem of the order of magnitude discrepancy in the expected and observed ratios of the Lyman and Balmer lines in quasars and active galaxies is reviewed. Whereas early photoionization models for the emission line regions predicted F(L-alpha)/F(H-beta) not less than 40, the observations give values for this ratio in the range 3-8. Attempts at explaining the observations have involved dust, both external and internal to the emission line regions, and improved treatments of the collisional processes and radiative transfer effects in dense (Ne about 10 to the 10th/cu cm), optically thick clouds. None of the effects considered is, by itself, able to explain all the observations, and a combination of several of them is probably required.

  11. Describing Changes in Undergraduate Students' Preconceptions of Research Activities

    Research has shown that students bring naïve scientific conceptions to learning situations which are often incongruous with accepted scientific explanations. These preconceptions are frequently determined to be misconceptions; consequentially instructors spend time to remedy these beliefs and bring students' understanding of scientific concepts to acceptable levels. It is reasonable to assume that students also maintain preconceptions about the processes of authentic scientific research and its associated activities. This study describes the most commonly held preconceptions of authentic research activities among students with little or no previous research experience. Seventeen undergraduate science majors who participated in a ten week research program discussed, at various times during the program, their preconceptions of research and how these ideas changed as a result of direct participation in authentic research activities. The preconceptions included the belief that authentic research is a solitary activity which most closely resembles the type of activity associated with laboratory courses in the undergraduate curriculum. Participants' views showed slight maturation over the research program; they came to understand that authentic research is a detail-oriented activity which is rarely successfully completed alone. These findings and their implications for the teaching and research communities are discussed in the article.

    One method of grading responses of the descriptive type is by using Structure of Observed Learning Outcomes (SOLO) taxonomy. The basis of this study was the expectation that if students were oriented to SOLO taxonomy, it would provide them an opportunity to understand some of the factors that teachers consider while grading descriptive responses and possibly develop strategies to improve scores. We first sampled the perceptions of 68 second-year undergraduate medical students doing the Respiratory System course regarding the usefulness of explicit discussion of SOLO taxonomy. Subsequently, in a distinct cohort of 20 second-year medical students doing the Central Nervous System course, we sought to determine whether explicit illustration of SOLO taxonomy combined with some advice on better answering descriptive test questions (to an experimental group) resulted in better student scores in a continuous assessment test compared with providing advice for better answering test questions but without any reference to SOLO taxonomy (the control group). Student ratings of the clarity of the presentation on SOLO taxonomy appeared satisfactory to the authors, as was student understanding of our presentation. The majority of participants indicated that knowledge of SOLO taxonomy would help them study and prepare better answers for questions of the descriptive type. Although scores in the experimental and control group were comparable, this experience nonetheless provided us with the motivation to orient students to SOLO taxonomy early on in the medical program and further research factors that affect students' development of strategies based on knowledge of SOLO taxonomy.

    Supermassive black holes (SMBHs) have been detected in the centers of most nearby massive galaxies. Galaxies today are not only the products of billions of years of galaxy mergers, but also billions of years of SMBH activity as active galactic nuclei (AGNs) that is connected to galaxy mergers. In this context, detection of AGN pairs should be relatively common. Observationally, however, dual AGNs are scant, being just a few percent of all AGNs. In this Letter, we investigate the triggering of AGN activity in merging galaxies via a suite of high-resolution hydrodynamical simulations. We follow the dynamics and accretion onto the SMBHs as they move from separations of tens of kiloparsecs to tens of parsecs. Our resolution, cooling, and star formation implementation produce an inhomogeneous, multi-phase interstellar medium, allowing us to accurately trace star formation and accretion onto the SMBHs. We study the impact of gas content, morphology, and mass ratio, focusing on AGN activity and dynamics across a wide range of relevant conditions. We test when the two AGNs are simultaneously detectable, for how long and at which separations. We find that strong dual AGN activity occurs during the late phases of the mergers, at small separations (<1-10 kpc) below the resolution limit of most surveys. Much of the SMBH accretion is not simultaneous, limiting the dual AGN fraction detectable through imaging and spectroscopy to a few percent, in agreement with observational samples.

    Underwater observation of active submarine lava flows from Kilauea volcano, Hawaii, in March-June 1989 revealed both pillow lava and highly channelized lava streams flowing down a steep and unconsolidated lava delta. The channelized streams were 0.7-1.5 m across and moved at rates of 1-3 m/s. The estimated flux of a stream was 0.7 m3/s. Jets of hydrothermal water and gas bubbles were associated with the volcanic activity. The rapidly moving channelized lava streams represent a previously undescribed aspect of submarine volcanism. -Author

    2015-02-01

    Current science education reforms and policy documents highlight the importance of environmental awareness and perceived need for activism. As "environmental problems are socially constructed in terms of their conceptualized effects on individuals, groups, other living things and systems research based on constructivist principles provides not only a coherent framework in which to theorize about learning, but also a context for understanding socially constructed issues" (Palmer and Suggate in Res Pap Educ 19(2), 2004, p. 208). This research study investigated the impacts of the learning processes structured based on the theories of constructionism and social constructivism on students' environmental awareness and perceived need for activism. Students constructed multimedia artifacts expressing their knowledge, attitudes, awareness, and activism about environmental issues through a constructionist design process. In addition, a social networking site was designed and used to promote social interaction among students. Twenty-two high school environmental science students participated in this study. A convergent mixed methods design was implemented to allow for the triangulation of methods by directly comparing and contrasting quantitative results with qualitative findings for corroboration and validation purposes. Using a mixed method approach, quantitative findings are supported with qualitative data (student video projects, writing prompts, blog entries, video projects of the students, observational field notes, and reflective journals) including spontaneous responses in both synchronous and asynchronous conversations on the social network to provide a better understanding of the change in students' environmental awareness and perceived need for activism. The findings of the study indicated that students' environmental awareness and perceived need for activism were improved at different scales (personal, community, global) throughout the constructionist and social

    To test the hypothesis that lecturing maximizes learning and course performance, we metaanalyzed 225 studies that reported data on examination scores or failure rates when comparing student performance in undergraduate science, technology, engineering, and mathematics (STEM) courses under traditional lecturing versus active learning. The effect sizes indicate that on average, student performance on examinations and concept inventories increased by 0.47 SDs under active learning (n = 158 studies), and that the odds ratio for failing was 1.95 under traditional lecturing (n = 67 studies). These results indicate that average examination scores improved by about 6% in active learning sections, and that students in classes with traditional lecturing were 1.5 times more likely to fail than were students in classes with active learning. Heterogeneity analyses indicated that both results hold across the STEM disciplines, that active learning increases scores on concept inventories more than on course examinations, and that active learning appears effective across all class sizes--although the greatest effects are in small (n ≤ 50) classes. Trim and fill analyses and fail-safe n calculations suggest that the results are not due to publication bias. The results also appear robust to variation in the methodological rigor of the included studies, based on the quality of controls over student quality and instructor identity. This is the largest and most comprehensive metaanalysis of undergraduate STEM education published to date. The results raise questions about the continued use of traditional lecturing as a control in research studies, and support active learning as the preferred, empirically validated teaching practice in regular classrooms.

    It has been proposed that heterogeneous chlorine activation on cirrus cloud particles near the tropopause could provide a chemical explanation for ozone trends in the midlatitude tropopause region. During the 1998 WAM (WB-57 Aerosol Mission) campaign, an in situ ClO instrument was deployed on the NASA WB-57 aircraft in the midlatitudes. On the 11 April 1998 flight, clear examples of enhancements to reactive chlorine in sunlit, wet, particle laden air near the tropopause were observed over eastern Wyoming (approximately 42\\deg N, 105\\deg E) at 11-12 km. The air being sampled appeared to contain evaporating cirrus, and the observed chlorine enhancements (up to 20% activation) were strongly correlated with both particle surface area and total water. Ozone values in this enhanced ClO region ranged from 80-300 ppbv, consistent with both tropospheric and lowermost stratospheric air. These observations suggest that near tropopause reactive chlorine enhancements likely occur in regions of recent stratospheric-tropospheric exchange providing water and increased particle surface area to otherwise relatively dry stratospheric air. Due to greater insolation, ozone loss rates in this region may be higher than those previously reported for similar active chlorine abundances at similar altitudes in the Arctic.

  4. Knowledge discovery in group activities through sequential observation analysis

    2014-06-01

    Understanding of Group Activities (GA) has significant applications in civilian and military domains. The process of understanding GA is typically involved with spatiotemporal analysis of multi-modality sensor data. Video imagery is one popular sensing modality that offers rich data, however, data associated with imagery source may become fragmented and discontinued due to a number of reasons (e.g., data transmission, or observation obstructions and occlusions). However, making sense out of video imagery is a real challenge. It requires a proper inference working model capable of analyzing video imagery frame by frame, extract and inference spatiotemporal information pertaining to observations while developing an incremental perception of the GA as they emerge overtime. In this paper, we propose an ontology based GA recognition where three inference Hidden Markov Models (HMM's) are used for predicting group activities taking place in outdoor environments and different task operational taxonomy. The three competing models include: a concatenated HMM, a cascaded HMM, and a context-based HMM. The proposed ontology based GA-HMM was subjected to set of semantically annotated visual observations from outdoor group activity experiments. Experimental results from GA-HMM are presented with technical discussions on design of each model and their potential implication to Persistent Surveillance Systems (PSS).

  5. Active Region Moss: Doppler Shifts from Hinode/EIS Observations

    2012-01-01

    Studying the Doppler shifts and the temperature dependence of Doppler shifts in moss regions can help us understand the heating processes in the core of the active regions. In this paper we have used an active region observation recorded by the Extreme-ultraviolet Imaging Spectrometer (EIS) onboard Hinode on 12-Dec- 2007 to measure the Doppler shifts in the moss regions. We have distinguished the moss regions from the rest of the active region by defining a low density cut-off as derived by Tripathi et al. (2010). We have carried out a very careful analysis of the EIS wavelength calibration based on the method described in Young, O Dwyer and Mason (2012). For spectral lines having maximum sensitivity between log T = 5.85 and log T = 6.25 K, we find that the velocity distribution peaks at around 0 km/s with an estimated error of 4 km/s. The width of the distribution decreases with temperature. The mean of the distribution shows a blue shift which increases with increasing temperature and the distribution also shows asymmetries towards blue-shift. Comparing these results with observables predicted from different coronal heating models, we find that these results are consistent with both steady and impulsive heating scenarios. Further observational constraints are needed to distinguish between these two heating scenarios.

    2003-12-01

    Teachers of general-audience science courses, astronomy department chairs, and K-12 standards-writing committees all agree that student understanding of the scientific habits of mind is one important goal of any science course. This paper reports the successful use of a problem-based learning approach where students asked to choose the next step in an observational astronomy research program. The course, "Black Holes and Cosmic Evolution," is a rather unusual version of Astronomy 101 which spends the first three weeks on the ways that astronomers search for black holes. The 136 students were given a list of black hole candidates (from Bailyn et al., ApJ 499, 368) and asked to work in groups of 4-5 to choose and justify one for further observations. They learned and used error analysis. They determined the X-ray properties of these objects with an on-line x-ray survey (http://skyview.gsfc.nasa.gov/). The group product was a paper that was, essentially, a standard NOAO observing proposal. The University of Delaware's access to telescopes through its newly-acquired membership in the SMARTS consortium (http://phoenix.astro.yale.edu/smarts/) provided some motivation. In short, these students, none of whom are science majors, were challenged to act like real observational astronomers. Some guidance was provided by the instructor and two undergraduate TA's. Did they rise to the challenge or did they flounder? They succeeded. All 30 groups presented credible papers. Several A-plus papers were so good that they could make up most of an actual observing proposal. A follow-up exam tested students' understanding of underlying concepts (e.g., using Kepler's Laws to analyze binary stars). The average score on these test questions was 89.2 (n=133). We plan to use some SMARTS time to observe student-selected targets. This research has been supported by the Distinguished Teaching Scholars program of the National Science Foundation (DUE-0308557).

  9. Continuous gravity observations at active volcanoes through superconducting gravimeters

    NASA Astrophysics Data System (ADS)

    Carbone, Daniele; Greco, Filippo

    2016-04-01

    Continuous gravity measurements at active volcanoes are usually taken through spring gravimeters that are easily portable and do not require much power to work. However, intrinsic limitations dictate that, when used in continuous, these instruments do not provide high-quality data over periods longer than some days. Superconducting gravimeters (SG), that feature a superconducting sphere in a magnetic field as the proof mass, provide better-quality data than spring gravimeters, but are bigger and need mains electricity to work, implying that they cannot be installed close to the active structures of high volcanoes. An iGrav SG was installed on Mt. Etna (Italy) in September 2014 and has worked almost continuously since then. It was installed about 6km from the active craters in the summit zone of the volcano. Such distance is normally too much to observe gravity changes due to relatively fast (minutes to days) volcanic processes. Indeed, mass redistributions in the shallowest part of the plumbing system induce short-wavelength gravity anomalies, centered below the summit craters. Nevertheless, thanks to the high precision and long-term stability of SGs, it was possible to observe low-amplitude changes over a wide range of timescales (minutes to months), likely driven by volcanic activity. Plans are in place for the implementation of a mini-array of SGs at Etna.

    2014-12-01

    Using recently established empirical calibrations for the impact of chromospheric activity on the radii, effective temperatures, and estimated masses of active low-mass stars and brown dwarfs, we reassess the shape of the initial mass function (IMF) across the stellar/substellar boundary in the Upper Sco star-forming region (age ∼ 5-10 Myr). We adjust the observed effective temperatures to warmer values using the observed strength of the chromospheric Hα emission, and redetermine the estimated masses of objects using pre-main-sequence evolutionary tracks in the H-R diagram. The effect of the activity-adjusted temperatures is to shift the objects to higher masses by 3%-100%. While the slope of the resulting IMF at substellar masses is not strongly changed, the peak of the IMF does shift from ≈0.06 to ≈0.11 M {sub ☉}. Moreover, for objects with masses ≲ 0.2 M {sub ☉}, the ratio of brown dwarfs to stars changes from ∼80% to ∼33%. These results suggest that activity corrections are essential for studies of the substellar mass function, if the masses are estimated from spectral types or from effective temperatures.

  11. Solar activities observed with the New Vacuum Solar Telescope

    2015-08-01

    The New Vacuum Solar Telescope is the most important facility of the Fuxian Solar Observatory in China. Based on the high spatial and temporal resolution NVST observations, we investigate the solar activities in the chromosphere and obtain some new results. (1) Observations of a flux rope tracked by filament activation (Yang et al. 2014a). The filament material is initially located at one end of the flux rope and fills in a section of the rope. Then the filament is activated and the material flows along helical threads, tracking the twisted flux rope structure. The flux rope can be detected in both low temperature and high temperature lines, and there exists a striking anti-correlation between the Hα and EUV lines, which could imply some mild heating of cool filament material to coronal temperatures during the filament activation. (2) Fine structures and overlying loops of homologous confined solar flares (Yang et al. 2014b). At the pre-flare stage, there exists a reconnection between small loops. During the flare processes, the overlying loops, some of which are tracked by activated dark materials, do not break out. These direct observations may illustrate the physical mechanism of confined flares, i.e., magnetic reconnection between the emerging loops and the pre-existing loops triggers flares and the overlying loops prevent the flares from being eruptive. (3) Magnetic reconnection between small-scale loops (Yang et al. 2015). We report the solid observational evidence of magnetic reconnection between two sets of small-scale loops. The observed signatures are consistent with the predictions by reconnection models. The thickness and length of the current sheet are determined to be about 420 km and 1.4 Mm, respectively. The reconnection process contains a slow step and a rapid step. We suggest that the successive slow reconnection changes the conditions around the reconnection site and disrupts the instability, thus leading to the rapid approach of the anti

  15. TRMM/LIS and PR Observations and Thunderstorm Activity

    NASA Astrophysics Data System (ADS)

    2005-12-01

    Thunderstorms observed by TRMM/PR and LIS have been investigating, and Lightning Research Group of Osaka University (LRG-OU) has unveiled several interesting features. Correlation between lightning activities and the snow depth of convective clouds may follow the power-five law. The power five law means that the flash density is a function of the snow-depth to power five. The definition of snow depth is the height of detectable cloud tops by TRMM/PR from the climatological freezing level, and it may be equivalent to the length of the portion where the solid phase precipitation particles exist. This is given by examining more than one million convective clouds, and we conclude that the power five law should be universal from the aspect of the statistic. Three thunderstorm active areas are well known as "Three World Chimneys", and those are the Central Africa, Amazon of the South America, and South East Asia. Thunderstorm activities in these areas are expected to contribute to the distribution of thermal energy around the equator to middle latitude regions. Moreover thunderstorm activity in the tropical region is believed to be related with the average temperature of our planet earth. That is why long term monitoring of lightning activity is required. After launching TRMM we have accumulated seven-year LIS observations, and statistics for three world chimneys are obtained. We have recognized the additional lightning active area, and that is around the Maracaibo lake in Venezuera. We conclude that this is because of geographical features of the Maracaibo lake and the continuous easterly trade wind. Lightning Activity during El Niño period is another interesting subject. LRGOU studies thunderstorm occurrences over west Indonesia and south China, and investigates the influence of El Nino on lightning . We compare the statistics between El Nino and non El Nino periods. We learn that the lightning activity during El Niño period is higher than non El Nino period instead

  16. Both novelty and expertise increase action observation network activity

    Our experiences with others affect how we perceive their actions. In particular, activity in bilateral premotor and parietal cortices during action observation, collectively known as the action observation network (AON), is modulated by one's expertise with the observed actions or individuals. However, conflicting reports suggest that AON activity is greatest both for familiar and unfamiliar actions. The current study examines the effects of different types and amounts of experience (e.g., visual, interpersonal, personal) on AON activation. fMRI was used to scan 16 healthy participants without prior experience with individuals with amputations (novices), 11 experienced occupational therapists (OTs) who had varying amounts of experience with individuals with amputations, and one individual born with below-elbow residual limbs (participant CJ), as they viewed video clips of goal-matched actions performed by an individual with residual limbs and by an individual with hands. Participants were given increased visual exposure to actions performed by both effectors midway through the scanning procedure. Novices demonstrated a large AON response to the initial viewing of an individual with residual limbs compared to one with hands, but this signal was attenuated after they received visual exposure to both effectors. In contrast, OTs, who had moderate familiarity with residual limbs, demonstrated a lower AON response upon initial viewing—similar to novices after they received visual exposure. At the other extreme, CJ, who has extreme familiarity with residual limbs both visually and motorically, shows a largely increased left-lateralized AON response, exceeding that of novices and experienced OTs, when viewing the residual limb compared to hand actions. These results suggest that a nuanced model of AON engagement is needed to explain how cases of both extreme experience (CJ) and extreme novelty (novices) can result in the greatest AON activity.

    2015-01-01

    Background: Lecture is a common traditional method for teaching, but it may not stimulate higher order thinking and students may also be hesitant to express and interact. The postgraduate (PG) students are less involved with undergraduate (UG) teaching. Team based small group active learning method can contribute to better learning experience. Aim: To-promote active learning skills among the UG students using small group teaching methods involving PG students as facilitators to impart hands-on supervised training in teaching and managerial skills. Methodology: After Institutional approval under faculty supervision 92 UGs and 8 PGs participated in 6 small group sessions utilizing the jigsaw technique. Feedback was collected from both. Observations: Undergraduate Feedback (Percentage of Students Agreed): Learning in small groups was a good experience as it helped in better understanding of the subject (72%), students explored multiple reading resources (79%), they were actively involved in self-learning (88%), students reported initial apprehension of performance (71%), identified their learning gaps (86%), team enhanced their learning process (71%), informal learning in place of lecture was a welcome change (86%), it improved their communication skills (82%), small group learning can be useful for future self-learning (75%). Postgraduate Feedback: Majority performed facilitation for first time, perceived their performance as good (75%), it was helpful in self-learning (100%), felt confident of managing students in small groups (100%), as facilitator they improved their teaching skills, found it more useful and better identified own learning gaps (87.5%). Conclusions: Learning in small groups adopting team based approach involving both UGs and PGs promoted active learning in both and enhanced the teaching skills of the PGs. PMID:26380201

    We use UV spectral observations of active regions with the Interface Region Imaging Spectrograph (IRIS) to investigate the properties of the coronal Fe xii 1349.4 Å emission at unprecedented high spatial resolution (∼0.33″). We find that by using appropriate observational strategies (i.e., long exposures, lossless compression), Fe xii emission can be studied with IRIS at high spatial and spectral resolution, at least for high-density plasma (e.g., post-flare loops and active region moss). We find that upper transition region (TR; moss) Fe xii emission shows very small average Doppler redshifts ({v}{{D}} ∼ 3 km s‑1) as well as modest non-thermal velocities (with an average of ∼24 km s‑1 and the peak of the distribution at ∼15 km s‑1). The observed distribution of Doppler shifts appears to be compatible with advanced three-dimensional radiative MHD simulations in which impulsive heating is concentrated at the TR footpoints of a hot corona. While the non-thermal broadening of Fe xii 1349.4 Å peaks at similar values as lower resolution simultaneous Hinode Extreme Ultraviolet Imaging Spectrometer (EIS) measurements of Fe xii 195 Å, IRIS observations show a previously undetected tail of increased non-thermal broadening that might be suggestive of the presence of subarcsecond heating events. We find that IRIS and EIS non-thermal line broadening measurements are affected by instrumental effects that can only be removed through careful analysis. Our results also reveal an unexplained discrepancy between observed 195.1/1349.4 Å Fe xii intensity ratios and those predicted by the CHIANTI atomic database.

    2005-06-01

    The importance of attitudes toward science has risen from widely accepted assumptions that achievement and attitude are positively interdependent and that affective variables are as important as cognitive variables in molding student learning. This report examines the effect on student attitudes toward learning chemistry in an active learning environment that has incorporated elements believed to positively influence student attitudes toward science including cooperative learning, hands-on activities, real-world applications, and engaging technology. These elements were considered for synergetic effects and not as individual contributors to the overall results. Two different sections of the same general chemistry course participated. The lecture setting was used as the control. Residualized gain scores were used to compare net changes in student attitudes. Data were analyzed for possible differences in gain for different academic majors. Anxiety in chemistry was monitored for the two class settings in three areas, learning in chemistry, chemistry evaluation, and chemical handling. Qualitative student feedback was also collected and is summarized in this report on the attitudinal aspects of instruction.

    Previous satellite observations of active volcanoes have been hampered by instruments that are primarily designed to measure surface reflectance of the Earth's vegetation. Sensors detecting radiation in the near-IR and IR are frequently saturated by highly radiant active volcanic features. Two satellite instruments, Hyperion and the Advanced Land Imager (ALI) on the Earth Observing -1 (EO-1) offer a means to circumvent saturation issues. Hyperion is a hyperspectral instrument that collects data in 242 narrow spectral bands between 0.4 and 2.5 microns and produces images that are 7.5 km x 100 km. For each 30m x 30m pixel, accurate atmospheric corrections and multiple component thermal models for lava flows can be generated. ALI is a Landsat-like instrument having 10 spectral bands at 0.4 - 2.35 microns. One of these, the 1.2 micron band, is sensitive to high temperature thermal anomalies such as overturning lava lakes and open lava channels. ALI also has a 10-m panchromtic band that allows for greater detailed mapping of volcanic features. ALI and Hyperion analyses for Erta Ale (Ethiopia), Mt. Etna (Sicily), Santiaguito (Guatemala), Popocatepetl (Mexico), and Mayon (Philippines) will be presented. While distribution of these data sets is limited to the EO-1 Science Team, the future of NASA's high spatial resolution terrestrial observation program will likely be based on a hybrid of these EO-1 sensors.

    Major recent tectonic process in the Eastern Alps involves the Neogene and Quaternary lateral extrusion of parts of the Eastern Alps towards the Pannonian Basin coeval with north-south shortening of the collision realm between the Adriatic Plate and the Bohemian Massif (European Plate). Within the framework of the FWF project "Speleotect" (2013-2017), we observe recent activity of the major fault systems of the Eastern Alps, such as the (1) Salzach-Ennstal-Mariazell-Puchberg (SEMP), (2) Mur-Mürz, (3) Periadriatic, (4) Lavanttal, and (5) Vienna Basin marginal Faults. Totally seven high-accuracy 3D crack-gauges TM71 with automated reading devices were installed in five selected karst caves with faults younger than the particular caves and correlated to one of these fault zones. The recorded micro-displacement events have been compared to known regional fault kinematics and to regional seismic activity (seismic data provided by the ZAMG). Already within the first year of observation, several micro displacement events were registered; these events sometimes revealed the same mechanisms as the geologically documented kinematics of the particular active faults, but in some cases performed completely opposite kinematics. These micro displacement events occurred in seismically rather quiet periods, however, usually about 1 - 10 days prior to local seismic events of different magnitudes (varying between ML 0.1 and 3.3). Further, in some caves gravitational mass movements were recorded that accompanied the tectonic moments.

    The Challenge Awards are designed to provide a unique perspective to students gifted in the arts and humanities from which to understand scientific endeavor by giving students an opportunity to participate in an ongoing research project. In the graduate program, seven students who had participated in previous Challenge Awards programs were selected to help develop the tools for Earth observations for the astronauts on the Space Radar Laboratory (SRL) missions. The goal of the Challenge Awards program was to prepare a training manual for the astronauts on the SRL missions. This paper describes the observations to be made by the astronauts on the SRL missions. The emphasis is on the dynamic seasonal features of the Earth's surface and atmosphere which justify the need for more than one flight of the SRL. Complete notebooks of the sites, global seasonal patterns, examples of radar and the Measurement of Air Pollution from Satellites data, and shuttle photographs have been given to each of the SRL crews.

  6. An Inquiry "Warm-Up" Activity: Preparing Students for an Active Classroom Community

    NASA Astrophysics Data System (ADS)

    Seagroves, S.

    2010-12-01

    An active learning community that engages in inquiry activities will employ strategies and structures that students from traditional classrooms may find unfamiliar or uncomfortable. These include group work, voicing questions, shifting from one part of an activity to another (and sometimes shifting groups at the same time), presenting informally to the group, and many others. In addition, the role of the instructor as facilitator rather than teacher may not be familiar to students. As inquiry activities become incorporated into the regular classroom curriculum at Maui Community College (through collaboration with the Professional Development Program as part of the Akamai Workforce Initiative), a need emerged to give students a "warm-up" early in the semester to help them practice these participation structures. This activity was designed to be used on the very first day of class, to be easy and accessible to students, and to give them practice with these features of inquiry activities that they would see again throughout the semester. In addition, the activity introduces the engineering technology concepts of requirements, trade-offs, and limitations. It is important to note that this activity is not in and of itself an inquiry activity; in fact the content and processes featured in the activity are not particularly challenging nor are they the main focus. Instead, this is a "warm-up" for inquiry, so that students gain some comfort with the unconventional features of inquiry activities. The particular activity presented is for 20-30 students in a ˜90 minute lab period, and highlights different imaging technologies of cameras; however, it is easily adaptable to other requirements, to different technology, or other needs.

  7. Students' and experts' perspectives on three learning and teaching activities.

    Nursing is a profession that closely related to human life, and nurses are required to demonstrate critical thinking and creativity in providing health care services. However, traditional teaching approaches usually limit students' autonomy and freedom of expressing their thoughts and feelings. In order to develop the corresponding competence of nursing students, I adopted three teaching innovations, namely writing poems, composing songs, and using role plays in a nursing problem-based learning class in a university in Hong Kong. According to students' reflective notes and comments from two international expert reviewers, participating in these activities is a valuable experience and students were able to develop clinical reasoning, empathy, team spirit, motivation to learn, creativity, and ability to summarise and reconstruct knowledge. It is hoped that more innovative learning activities will be implemented, to prepare professional and ethical nurses in the future. It is also hoped that this study could provide other PBL educators some insights in innovative problem-based learning activities. PMID:24679519

  8. Spectroscopic Observations of Fe XVIII in Solar Active Regions

    Teriaca, Luca; Warren, Harry P.; Curdt, Werner

    2012-08-01

    The large uncertainties associated with measuring the amount of high temperature emission in solar active regions (ARs) represents a significant impediment to making progress on the coronal heating problem. Most current observations at temperatures of 3 MK and above are taken with broadband soft X-ray instruments. Such measurements have proven difficult to interpret unambiguously. Here, we present the first spectroscopic observations of the Fe XVIII 974.86 Å emission line in an on-disk AR taken with the SUMER instrument on SOHO. Fe XVIII has a peak formation temperature of 7.1 MK and provides important constraints on the amount of impulsive heating in the corona. Detailed evaluation of the spectra and comparison of the SUMER data with soft X-ray images from the X-Ray Telescope on Hinode confirm that this line is unblended. We also compare the spectroscopic data with observations from the Atmospheric Imaging Assembly (AIA) 94 Å channel on the Solar Dynamics Observatory. The AIA 94 Å channel also contains Fe XVIII, but is blended with emission formed at lower temperatures. We find that it is possible to remove the contaminating blends and form relatively pure Fe XVIII images that are consistent with the spectroscopic observations from SUMER. The observed spectra also contain the Ca XIV 943.63 Å line that, although a factor 2-6 weaker than the Fe XVIII 974.86 Å line, allows us to probe the plasma around 3.5 MK. The observed ratio between the two lines indicates (isothermal approximation) that most of the plasma in the brighter Fe XVIII AR loops is at temperatures between 3.5 and 4 MK.

    Context. We study upflows at the edges of active regions, called AR outflows, using multi-instrument observations. Aims: This study intends to provide the first direct observational evidence of whether chromospheric jets play an important role in furnishing mass that could sustain coronal upflows. The evolution of the photospheric magnetic field, associated with the footpoints of the upflow region and the plasma properties of active region upflows is investigated with the aim of providing information for benchmarking data-driven modelling of this solar feature. Methods: We spatially and temporally combine multi-instrument observations obtained with the Extreme-ultraviolet Imaging Spectrometer on board the Hinode, the Atmospheric Imaging Assembly and the Helioseismic Magnetic Imager instruments on board the Solar Dynamics Observatory and the Interferometric BI-dimensional Spectro-polarimeter installed at the National Solar Observatory, Sac Peak, to study the plasma parameters of the upflows and the impact of the chromosphere on active region upflows. Results: Our analysis shows that the studied active region upflow presents similarly to those studied previously, i.e. it displays blueshifted emission of 5-20 kms-1 in Fe xii and Fe xiii and its average electron density is 1.8 × 109 cm-3 at 1 MK. The time variation of the density is obtained showing no significant change (in a 3σ error). The plasma density along a single loop is calculated revealing a drop of 50% over a distance of ~20 000 km along the loop. We find a second velocity component in the blue wing of the Fe xii and Fe xiii lines at 105 kms-1 reported only once before. For the first time we study the time evolution of this component at high cadence and find that it is persistent during the whole observing period of 3.5 h with variations of only ±15 kms-1. We also, for the first time, study the evolution of the photospheric magnetic field at high cadence and find that magnetic flux diffusion is

  20. Multi-wavelength Observations of Solar Active Region NOAA 7154

    Bruner, M. E.; Nitta, N. V.; Frank. Z. A.; Dame, L.; Suematsu, Y.

    2000-01-01

    We report on observations of a solar active region in May 1992 by the Solar Plasma Diagnostic Experiment (SPDE) in coordination with the Yohkoh satellite (producing soft X-ray images) and ground-based observatories (producing photospheric magnetograms and various filtergrams including those at the CN 3883 A line). The main focus is a study of the physical conditions of hot (T is approximately greater than 3 MK) coronal loops at their foot-points. The coronal part of the loops is fuzzy but what appear to be their footpoints in the transition region down to the photosphere are compact. Despite the morphological similarities, the footpoint emission at 10(exp 5) K is not quantitatively correlated with that at approximately 300 km above the tau (sub 5000) = 1 level, suggesting that the heat transport and therefore magnetic field topology in the intermediate layer is complicated. High resolution imaging observations with continuous temperature coverage are crucially needed.

  1. Inference of other's internal neural models from active observation.

    PubMed

    Kim, Kyung-Joong; Cho, Sung-Bae

    2015-02-01

    Recently, there have been several attempts to replicate theory of mind, which explains how humans infer the mental states of other people using multiple sensory input, with artificial systems. One example of this is a robot that observes the behavior of other artificial systems and infers their internal models, mapping sensory inputs to the actuator's control signals. In this paper, we present the internal model as an artificial neural network, similar to biological systems. During inference, an observer can use an active incremental learning algorithm to guess an actor's internal neural model. This could significantly reduce the effort needed to guess other people's internal models. We apply an algorithm to the actor-observer robot scenarios with/without prior knowledge of the internal models. To validate our approach, we use a physics-based simulator with virtual robots. A series of experiments reveal that the observer robot can construct an "other's self-model", validating the possibility that a neural-based approach can be used as a platform for learning cognitive functions.

  6. Observations on studies useful to asbestos operations and management activities

    SciTech Connect

    Wilmoth, R.C.; Powers, T.J.; Millette, J.R.

    1991-01-01

    Asbestos-containing materials found in buildings may release asbestos fibers into the air. Some of these fibers will eventually settle and attach to room surfaces (walls, furnishings, equipment, floors, and carpet) as part of normal dust. Activities like dusting, sweeping and vacuuming are likely to re-entrain the dust causing exposure to airborne asbestos. The paper discusses data that are largely observational in nature, but are illustrative of general trends of interest to those individuals dealing with the day-to-day problems of asbestos in buildings.

    2013-01-01

    Background: Physical activity is one of the leading health indicators. The objective was to study the prevalence and patterns of physical activity among young adults. Methods: 259 Medical students (Men: Women = 116:143) in the age group of 18–22 yrs were interviewed using the official English long version of the International Physical Activity Questionnaire (IPAQ). The total level of physical activity and activity in each of the 4 life domains – work, transport, domestic and gardening and leisure-time were estimated and was expressed as metabolic equivalent-hours per week (MET-hour/week). Results: 41.3 % showed high levels of physical activity, 43.2% and 15.4 % of students showed moderate level and low level of physical activity respectively. 84.6 % (n=219) were engaged in work related activity and 80.7% (n= 209) showed transport related activity. Domestic and gardening physical activity represented 63.7 % (n=165) of individuals total activity and 67.2% of students showed leisure time activity. The average time spent in sitting was 7.06 hrs/day. The median of the total physical activity for the whole sample was 39.13 MET/hour/week and 18.10 for work, 4.40 for transportation, 2.60 for domestic and gardening and 4 for leisure-time activity. There was significant gender difference observed with women having low physical activity. Conclusion: This study provides baseline information about the physical activity levels and patterns including sitting hours among Indian young adults using IPAQ that can used for comparison of data across different parts of world.

    2012-01-01

    Background Several studies have reported on the health benefits of applying an integrated complementary health care model. Purpose This paper presents the results of pilot research focusing on the observations massage therapy students made about complementary health care education and integration during massage, chiropractic, and acupuncture treatments at two university clinics. Setting: Observations took place at Northwestern Health Sciences University’s associated clinics that offered massage, chiropractic, and acupuncture. Research Design: Students directly observed how clinicians and interns educated their patients and integrated other forms of complementary health care into their practice. Participants: chiropractors, massage therapists, and acupuncturists, and their patients. All participants were English-speaking and 18–65 years old. Main Outcome Measures: Observations recorded by students in journals about education and integration during massage therapy, chiropractic, and acupuncture treatments were coded and counted. Results Qualitative observations showed that clinicians and interns educated patients to some degree, but the clinicians were less apt to integrate other modalities than the interns. Conclusions Observations support that professional integrity may limit clinicians in their ability to integrate multiple modalities of health care while treating patients. Since it is well established that integration of multiple health care modalities is beneficial to patient health, it is recommended that clinics assist their clinical staff in applying an integrative approach to their practice.

  12. An investigation of the impact of selected prereading activities on student content learning through laboratory activities

    NASA Astrophysics Data System (ADS)

    Kass, Jesse (Shaya)

    This study investigated whether two prereading activities impacted student learning from hands-on science activities. The study was based on constructivist learning theory. Based on the work of Piaget, it was hypothesized that students who activated prior knowledge would learn more from the activities. Based on the work of Vygotsky it was hypothesized that students who talk more and write more would learn more from the activity. The K-W-L chart and anticipation guide strategies were used with eighth grade students at Graves Middle School in Whittier, California before learning about levers and convection currents. D. M. Ogle (1986) created the three-column K-W-L chart to have students activate prior knowledge. In the first column, the students write what they already know about a subject, in the second column, the students write what they want to know about the subject, and the students complete the third column after learning about a subject by writing answers to the questions that they asked in the second column. Duffelmeyer (1994) created the anticipation guide based on Herber's (1978) reasoning guide. In the anticipation guide, the teacher creates three or four sentences that convey the major ideas of the topic and the students either agree or disagree with the statements. After learning about the topic, students revisit their answers and decide if they were correct or incorrect and they must defend their choices. This research used the Solomon (1947) four-square design and compared both the experimental groups to a control group that simply discussed the concepts before completing the activity. The research showed no significant difference between the control group and either of the treatment groups. The reasons for the lack of significant differences are considered. It was hypothesized that since the students were unfamiliar with the prereading activities and did not have much experience with using either writing-to-learn or talking-to-learn strategies, the

    The purpose of this study was to evaluate both video modeling and observational learning to teach age-appropriate recreation and leisure skills (i.e., accessing video games) to students with autism spectrum disorder. Effects of video modeling were evaluated via a multiple probe design across participants and criteria for mastery were based on these results. Secondary measures were collected on observational learning across participants and behaviors. Participants included 4 children with autism, ages 8-11, who were served in self-contained special education classrooms. Results indicated a functional relation between video modeling and increased independence in gaming; observational learning occurred for at least some steps across students. Results, implications for practitioners, limitations, and ideas for future research are discussed. PMID:27271933

    We report on observations of TeV-selected active galactic nuclei (AGNs) made during the first 5.5 months of observations with the Large Area Telescope (LAT) on-board the Fermi Gamma-ray Space Telescope (Fermi). In total, 96 AGNs were selected for study, each being either (1) a source detected at TeV energies (28 sources) or (2) an object that has been studied with TeV instruments and for which an upper limit has been reported (68 objects). The Fermi observations show clear detections of 38 of these TeV-selected objects, of which 21 are joint GeV-TeV sources, and 29 were not in the third EGRET catalog. For each of the 38 Fermi-detected sources, spectra and light curves are presented. Most can be described with a power law of spectral index harder than 2.0, with a spectral break generally required to accommodate the TeV measurements. Based on an extrapolation of the Fermi spectrum, we identify sources, not previously detected at TeV energies, which are promising targets for TeV instruments. Evidence for systematic evolution of the γ-ray spectrum with redshift is presented and discussed in the context of interaction with the extragalactic background light.

    2006-01-01

    In this paper we investigate the thermal and dynamic properties of dynamic structures in and around a prominence channel observed on the limb on 17 April 2003. Observations were taken with the Solar and Heliospheric Observatory's Solar Ultraviolet Measurements of Emitted Radiation (SOHO/SUMER) in lines formed at temperatures from 80,000 to 1.6 MK. The instrument was pointed to a single location and took a series of 90 s exposures. Two-dimensional context was provided by the Transition Region and Coronal Explorer (TRACE) in the UV and EUV and the Kanzelhohe Solar Observatory in H-alpha. Two dynamic features were studied in depth: an activated prominence and repeated motions in a loop near the prominence. We calculated three-dimensional geometries and trajectories, differential emission measure, and limits on the mass, pressure, average density, and kinetic and thermal energies. These observations provide important tests for models of dynamics in prominences and cool (approx. 10(exp 5) K)loops, which will ultimately lead to a better understanding the mechanism(s) leading to energy and mass flow in these solar features.

  19. TRACE and SVST Observations of an Active-Region Filament

    NASA Astrophysics Data System (ADS)

    van Ballegooijen, A. A.; Deluca, E. E.

    1999-05-01

    In June 1998 the Transition Region and Coronal Explorer (TRACE) observed filaments and prominences in coordination with various ground-based solar observatories, including the Swedish Vacuum Solar Telescope (SVST) on La Palma. Here we present results for an active-region filament observed on June 21-22. This horse-shoe shaped filament had a "barb" that reached down from the filament spine to the chomosphere below. We use high-resolution images obtained at the SVST on June 21 from 18:03 to 19:04 UT to study the fine structure and dynamics of plasmas in the barb and other parts of the filament. The data consist of narrowband Hα images taken with the Lockheed Tunable Filtergraph operating at a cadence of 20 s. We present Doppler maps derived from these images. The filament erupted six hours after the SVST observations. The eruption was observed with TRACE, which obtained images in Fe IX/X 171, Fe XII 195, Fe XV 284 and H I Lyalpha . At the start of the event, a thin bright loop appears high above the filament at the location of the barb. We interpret this feature as the outline of a magnetic "bubble" which forms as a result of kink instability in the magnetic field that supports the filament. The bright loop appears to be due to particle acceleration and impulsive heating along certain field lines on the periphery of this magnetic structure. A few minutes later, the dark filament threads turn into emission and move outward, exhibiting a helical structure. We discuss the magnetic structure of the barb and its possible role in the filament eruption.

  7. Magnetic observations during the recent declining phase of solar activity

    NASA Astrophysics Data System (ADS)

    Smith, E. J.

    Changes in the heliospheric magnetic field during the recent declining phase in solar activity are reviewed and compared with observations during past sunspot cycles. The study is based principally on data obtained by IMP-8 and Ulysses. The field magnitude is found to have increased during the declining phase until it reached a maximum value of 11.5nT in approximately 1991.5, approximately two years after sunspot maximum. The field of the sun's south pole became negative after a reversal in early 1990. The sector structure disappeared at Ulysses in April 1993 when the latitude of the spacecraft was -30 deg revealing a low inclination of the heliospheric current sheet. A large outburst of solar activity in March 1991 caused four Coronal Mass Ejections (CMEs) and numerious shocks at the location of Ulysses. Following a delay of more than a year, a series of recurrent high speed streams and Corotating Interaction Regions commenced in July 1992 which were observed by IMP-8, Ulysses and Voyager 2. In all these respects, the behavior of the magnetic field mimics that seen in the two earlier sunspot cycles. The comprehensive data set suggests a correlation between the absolute value of B and sunspot number. The major solar cycle variations in the radial component (and magnitude) of the field have been successfully reproduced by a recent model consisting of a tilted solar dipole, whose strength and tilt undergo characteristic changes over the sunspot cycle, and the heliospheric current sheet. The large outbursts of activity in mid-1972, mid-1982 and the first quarter of 1991 may represent a characteristic last 'gasp' of solar activity before the sun evolves to a different state. The recurrent high speed streams in 1973, 1984 and 1992 accompany the developemnt of large asymetrical polar coronal holes and the growth in intensity of the polar cap fields. After they endure for about one year, the polar coronal holes recede and the high speed streams are replaced by weaker

The field magnitude is found to have increased during the declining phase until it reached a maximum value of 11.5nT in approximately 1991.5, approximately two years after sunspot maximum. The field of the sun's south pole became negative after a reversal in early 1990. The sector structure disappeared at Ulysses in April 1993 when the latitude of the spacecraft was -30 deg revealing a low inclination of the heliospheric current sheet. A large outburst of solar activity in March 1991 caused four Coronal Mass Ejections (CMEs) and numerious shocks at the location of Ulysses. Following a delay of more than a year, a series of recurrent high speed streams and Corotating Interaction Regions commenced in July 1992 which were observed by IMP-8, Ulysses and Voyager 2. In all these respects, the behavior of the magnetic field mimics that seen in the two earlier sunspot cycles. The comprehensive data set suggests a correlation between the absolute value of B and sunspot number. The major solar cycle variations in the radial component (and magnitude) of the field have been successfully reproduced by a recent model consisting of a tilted solar dipole, whose strength and tilt undergo characteristic changes over the sunspot cycle, and the heliospheric current sheet. The large outbursts of activity in mid-1972, mid-1982 and the first quarter of 1991 may represent a characteristic last 'gasp' of solar activity before the sun evolves to a different state. The recurrent high speed streams in 1973, 1984 and 1992 accompany the developemnt of large asymetrical polar coronal holes and the growth in intensity of the polar cap fields. After they endure for about one year, the polar coronal holes recede and the high speed streams are replaced by weaker

  9. Using Art to Teach Students Science Outdoors: How Creative Science Instruction Influences Observation, Question Formation, and Involvement

    NASA Astrophysics Data System (ADS)

    Cone, Christina Schull

    Elementary education has become increasingly divided into subjects and focused on the demand for high math and reading scores. Consequently, teachers spend less time devoted to science and art instruction. However, teaching art and science is crucial to developing creative and rational thinking, especially for observation and questioning skills. In this study, third grade students attending an urban school in Portland, Oregon received instruction of an art strategy using observational and quantifying drawing techniques. This study examines, "Will an art strategy observing the local environment help students make observations and ask questions?" and "In what ways are student learning and perspectives of science affected by the art strategy?" The independent variable is the art strategy developed for this study. There are three dependent variables: quality of student observations, quality of questions, and themes on student learning and perspectives of science. I predicted students would develop strong observation and questioning skills and that students would find the strategy useful or have an increased interest in science. The art scores were high for relevance and detail, but not for text. There were significant correlations between art scores and questions. Interviews revealed three themes: observations create questions, drawing is helpful and challenging, and students connected to science. By examining science through art, students were engaged and created strong observations and questions. Teachers need to balance unstructured drawing time with scaffolding for optimal results. This study provides an integrated science and art strategy that teachers can use outdoors or adapt for the classroom.

    Active learning is an instructional method in which students become engaged participants in the classroom through the use of in-class written exercises, games, problem sets, audience-response systems, debates, class discussions, etc. Despite evidence supporting the effectiveness of active learning strategies, minimal adoption of the technique has occurred in many professional programs. The goal of this study was to compare the perceptions of active learning between students who were exposed to active learning in the classroom (n = 116) and professional-level physiology faculty members (n = 9). Faculty members reported a heavy reliance on lectures and minimal use of educational games and activities, whereas students indicated that they learned best via the activities. A majority of faculty members (89%) had observed active learning in the classroom and predicted favorable effects of the method on student performance and motivation. The main reported barriers by faculty members to the adoption of active learning were a lack of necessary class time, a high comfort level with traditional lectures, and insufficient time to develop materials. Students hypothesized similar obstacles for faculty members but also associated many negative qualities with the traditional lecturers. Despite these barriers, a majority of faculty members (78%) were interested in learning more about the alternative teaching strategy. Both faculty members and students indicated that active learning should occupy portions (29% vs. 40%) of face-to-face class time. PMID:25179615

    The scientific justification for an observing campaign to study the quantitative magnetic and plasma properties of coronal loops in active regions is presented. The SOHO (Solar and Heliospheric Observatory) instruments of primary relevance are CDS (Coronal Diagnostic Spectrometer), EIT, SUMER (Solar Ultraviolet Measurement of Emitted Radiation), and MDI. The primary ground based instruments would be the VLA (Very Large Array), the Owens Valley Radio Observatory, and vector and longitudinal field magnetographs. Similar campaigns have successfully been carried out with the Solar Maximum Mission x-ray polychromator and the Soft X-ray Imaging Sounding Rocket Payload (CoMStOC '87), the Goddard Solar EUV Rocket Telescope and Spectrograph, the Lockheed Solar Plasma Diagnostics Experiment rocket payload, and the Soft X-ray Telescope in Yohkoh (CoMStoc '92). The scientific payoff from such a campaign is discussed in light of the results from these previous campaigns.

    We describe the development and implementation of an instructional design that focused on bringing multiple forms of active learning and student-centered pedagogies to a one-semester, undergraduate introductory biology course for both majors and nonmajors. Our course redesign consisted of three major elements: 1) reordering the presentation of the course content in an attempt to teach specific content within the context of broad conceptual themes, 2) incorporating active and problem-based learning into every lecture, and 3) adopting strategies to create a more student-centered learning environment. Assessment of our instructional design consisted of a student survey and comparison of final exam performance across 3 years—1 year before our course redesign was implemented (2006) and during two successive years of implementation (2007 and 2008). The course restructuring led to significant improvement of self-reported student engagement and satisfaction and increased academic performance. We discuss the successes and ongoing challenges of our course restructuring and consider issues relevant to institutional change. PMID:19723815

    2016-01-01

    The VERITAS Observatory, located at the Fred Lawrence Whipple Observatory near Tucson, Arizona is one of the world's most sensitive detectors of very-high-energy (VHE; E>100GeV) gamma rays. With an array of four 12-m telescopes, VERITAS detects the Cherenkov light emitted from air showers initiated by astrophysical gamma rays. A sequence of upgrades completed in 2012 aimed at lowering the energy threshold resulted in the instrument being sensitive to gamma rays between 85 GeV and 30 TeV. Fully operational since 2007, VERITAS has so far detected 54 VHE gamma-ray objects in eight different source classes. The active galactic nuclei (AGN) class comprises the majority of these detections, with 34 sources that include several radio galaxies but are predominantly blazars (AGN with relativistic jets pointing towards Earth). The scientific importance of VHE detections of AGN includes studying the details of emission mechanisms in blazars and elucidating whether they are sources of ultra-high-energy cosmic rays and astrophysical neutrinos. Additionally VHE gamma-ray observations can be used to gain cosmological insights such as placing limits on the intergalactic magnetic field (IGMF) and the extragalactic background light (EBL), which comprises all the diffuse starlight in the universe. This presentation will summarize the VERITAS AGN observing program and highlight a few recent results.

  18. High-Resolution Observations of a Filament showing Activated Barb

    2012-07-01

    Analysis of a filament showing an activated barb using observations from the Dutch Open Telescope (DOT) on 2010 August 20 are presented. The DOT takes Doppler images in Hα, among other wavelengths, in a region about 110 × 110 arcsec^{2} in area, at a cadence of 30~seconds. The offline image restoration technique of speckle reconstruction is applied to obtain diffraction limited images. The filament developed a new barb in 10~minutes, which disappeared within the next 35~minutes. Such a rapid formation and disappearance of a filament barb is unusual, and has not been reported earlier. Line-of-sight velocity maps were constructed from the Doppler images of the target filament. We observe flows in the filament spine towards the barb location prior to its formation, and flows in the barb towards the spine during its disappearance. Photospheric magnetograms from Heliospheric Magnetic Imager on board the Solar Dynamics Observatory, at a cadence of 45~seconds, were used to determine the changes in magnetic flux in the region surrounding the barb location. The variation of magnetic flux in this duration supports the view that barbs are rooted in minor magnetic polarity. Our analysis shows that barbs can be short-lived and formation and disappearance of the barb was associated with cancellation of magnetic flux.

    2015-04-01

    MESSENGER magnetic field and plasma measurements taken during crossings of Mercury's magnetotail from 2011 to 2014 have been examined for evidence of substorm activity. A total of 32 events were found during which an Earth-like growth phase was followed by clear near-tail expansion phase signatures. During the growth phase, the lobe of the tail loads with magnetic flux while the plasma sheet thins due to the increased lobe magnetic pressure. MESSENGER is often initially in the plasma sheet and then moves into the lobe during the growth phases. The averaged time scale of the loading is around 1 min, consistent with previous observations of Mercury's Dungey cycle. The dipolarization front that marks the initiation of the substorm expansion phase is only a few seconds in duration. The spacecraft then abruptly enters the plasma sheet due to the plasma sheet expansion as reconnection-driven flow from the near-Mercury neutral line encounters the stronger magnetic fields closer to the planet. Substorm activity in the near tail of Mercury is quantitatively very similar to the Earth despite the very compressed time scale.

    During the period from 1992 May to early 1992 November, the Energetic Gamma-Ray Experiment Telescope (EGRET) on board the Compton Gamma Ray Observatory obtained high-energy gamma-ray data for most of the sky. A total of 18 active galaxies have been seen with high certainty, and it is expected that more will be found in the data when a more thorough analysis is complete. All of those that have been seen are radio-loud quasars or BL Lacertae objects; most have already been identified as blazars. No Seyfert galaxies have been found thus far. If the spectra are represented as a power law in energy, spectral slopes ranging from approximately -1.7 to -2.4 are found. A wide range of z-values exits in the observed sample, eight having values in excess of 1.0. Time variations have been seen, with the timescale for a significant change being as short as days in at least one case. These results imply the existence of very large numbers of relativistic particles, probably close to the central object. Although a large extrapolation is required, their existence also suggests that these active galactic nuclei may be the source of the extragalactic cosmic rays.

  1. Exploring students' perceptions and performance on predict-observe-explain tasks in high school chemistry laboratory

    NASA Astrophysics Data System (ADS)

    Vadapally, Praveen

    This study sought to understand the impact of gender and reasoning level on students' perceptions and performances of Predict-Observe-Explain (POE) laboratory tasks in a high school chemistry laboratory. Several literature reviews have reported that students at all levels have not developed the specific knowledge and skills that were expected from their laboratory work. Studies conducted over the last several decades have found that boys tend to be more successful than girls in science and mathematics courses. However, some recent studies have suggested that girls may be reducing this gender gap. This gender difference is the focal point of this research study, which was conducted at a mid-western, rural high school. The participants were 24 boys and 25 girls enrolled in two physical science classes taught by the same teacher. In this mixed methods study, qualitative and quantitative methods were implemented simultaneously over the entire period of the study. MANOVA statistics revealed significant effects due to gender and level of reasoning on the outcome variables, which were POE performances and perceptions of the chemistry laboratory environment. There were no significant interactions between these effects. For the qualitative method, IRB-approved information was collected, coded, grouped, and analyzed. This method was used to derive themes from students' responses on questionnaires and semi-structured interviews. Students with different levels of reasoning and gender were interviewed, and many of them expressed positive themes, which was a clear indication that they had enjoyed participating in the POE learning tasks and they had developed positive perceptions towards POE inquiry laboratory learning environment. When students are capable of formal reasoning, they can use an abstract scientific concept effectively and then relate it to the ideas they generate in their minds. Thus, instructors should factor the nature of students' thinking abilities into their

    Scientific literacy has been defined as the foremost challenge of this decade (AAAS, 2012). The Geological Society of American in its position statement postis that due to the systemic nature of the discipline of earth science, it is the most effective way to engage students in STEM disciplines. Given that the most common place for exposure to earth sciences is at the freshman level for non majors, we decided to transform a freshman introductory geology course to an active, student centered course, using an inquiry based approach. Our focus was to ensure the students saw the earth sciences as broadly applicative field, and not an esoteric science. To achieve this goal, we developed a series of problems that required the students to apply the concepts acquired through their self guided learning into the different topics of the course. This self guided learning took the form of didactic content uploaded into the learning management system (the various elements used to deliver the content were designed video clips, short text based lectures, short formative assessments, discussion boards and other web based discovery exercises) with the class time devoted to problem solving. A comparison of student performance in the active learning classroom vs. a traditional classroom as measured on a geoscience concept inventory (the questions were chosen by a third party who was not teaching either courses) showed that the the students in the active learning classroom scored 10% higher on the average in comparison to the traditional class. In addition to this heightened performance, the students in the active classroom also showed a higher degree of content retention 8 weeks after the semester had ended. This session will share the design process, some exercises and efficacy data collected.

    We present phase-diversity corrected G-band 4305 Å and 4364 Å continuum image time series showing the formation of a micropore in a small active region near disk center. The data were acquired at the Swedish Vacuum Solar Telescope on La Palma in June of 1997 and post-processed using the Phase Diverse Speckle (PDS) algorithm to produce diffraction limited images throughout the majority of both time series. The micropore dataset comprises a 29x29 Mm field of view and spans 5.1 hours with a 38 second cadence. The micropore forms in a strong sink area that can be seen to ``collect" many G-band bright points over the first 2 hours of the observation. During this time there is an occasional darkening at the sink point that may be the first unstable phase of the micropore formation. Once a stable dark pore forms in the flowfield, it grows to a maximum diameter of 1.2 Mm in approximately 1.9 hours. The pore persists for another 35 minutes before apparently being broken up by the intergranular flowfield. The total ``lifetime" of the stable pore phase is 2.5 hours. A separate nearby micropore of 1.5 Mm maximum diameter exists for the entire 5.2 hour data span. We show G-band and continuum movies of the micropore formation, correlation tracking flowfield analyses, G-band bright point tracking results, and area versus time plots for the micropore formation lifetime. The observational data are compared with fully compressible 3D MHD numerical simulations which show the development of a similar micropore structure within the computational domain. This research was supported by NASA SR&T grant NASW-98008, The Royal Swedish Academy of Sciences, NSF and NASA funding at Michigan State University, and Lockheed Martin IRAD funding.

  8. An Action Research Inquiry into the Relationship Among Aerobic Activities, Memory, and Stress with Students Identified as Gifted

    NASA Astrophysics Data System (ADS)

    Ford, Denise Marie

    Students identified as gifted come from varying socio-economic strata and nationalities with a range of talents and temperaments comprising a diverse community. They may experience stress for a variety of reasons. Although a certain amount of stress can enhance the learning process, too much stress can impede learning, especially memory. Strategies have been offered for relieving stress, yet the benefits of physical activities as stress reducers for the gifted have frequently been overlooked. The purpose of this study was to investigate the relationship among aerobic activity, stress, and memory ability in students in an elementary school gifted program. An exceptional aspect of this research was that the students were an integral part of their own study. As co-researchers they had a vested interest in what they were doing, enhancing the significance of the experience and heightening learning. This action research project conducted in a mid-western school district with fourth and fifth grade students examined the impact of aerobic movement on physical indicators of stress and memory. The study lasted twelve weeks with data collected on physical indicators of stress, memory test scores, parent observations, interviews with students, a parent focus group session, observational data, student comments, and investigator/teacher journal. By infusing regular exercise into curricula, stress levels in students identified as gifted were examined. Students' scores on declarative memory tasks conducted with and without an accompanying aerobic activity were documented. Students learned of the delicate relationship between stress and memory as they studied the physiology of the brain. Twenty-four hour retention rates of declarative memory items were higher when a 20-minute aerobic activity intervention preceded the memory activity. Perceived stress levels were lowered for 14 of the 16 co-researchers. Students indicated a positive attitude toward physical activity and its

    In China, where cancers and cardiovascular disease are the major causes of morbidity and mortality, an important role for preventive medicine has emerged. Therefore, preparing China's medical students to tackle contemporary health problems requires attention to nutrition and health promotion in the medical curriculum. To evaluate the effectiveness of a nutrition education activity for medical students, a two-group pre-test/post-test nutrition education program was conducted in a medical university in south-western China (n=300 per group). Students in another south-western Chinese medical university served as controls (n= 150 per group). Special features of the intervention were: (1) nutrition education materials developed from (a) the results of a pre-test survey of medical students and (b) discussions with medical students, faculty, and physicians; and (2) a multi-channel delivery, which included a classroom lecture-discussion; a nutrition knowledge competition; a handout providing a day's dietary allotment; campus radio and movie theatre announcements, and posters. Analysis of variance, chi-square, and t-tests showed a significant increase (P<0.05) in nutrition knowledge, but not in nutrition attitude score. The final nutrition knowledge and attitude scores were also found to be related to the students' increased exposure to the various channels (P<0.001). Also observed was an increase in the consumption of soybean and dairy products (P<0.05). It is concluded that the method is a useful and practical model for designing and developing student nutrition education activities in China, as well as demonstrating nutrition and health education methods among the medical university community.

    2014-01-01

    Background In this observational study, we aimed to see whether transition in Saudi students entering university life could be a breeding stage for cardiometabolic risk factor emergence and clustering. Methods A total of 1878 apparently healthy Saudi students of the Preparatory Year, King Saud University, Riyadh, KSA (1112 men and 766 women) spanning 2 academic years were included. They were divided into 2 groups based on the validated perceived stress test (PST). Anthropometrics were obtained and fasting blood samples were collected for measurement of fasting blood glucose and a lipid profile. Results PST score (>27) considered indicative of stress was noted in 44.4% of students. The prevalence of this score was higher in women than in men (49.7% versus 40.7%). The prevalence of obesity, hypertension and dyslipidemia was significantly higher in men than women (p < 0.01), and this was even more apparent among stressed men, who had a significantly higher prevalence of all the above cardiometabolic factors than the non-stressed ones (p < 0.01). Conclusion Perceived stress is alarmingly high among Saudi students entering universities. This study sheds light on the social responsibility of universities in promoting a healthy lifestyle, particularly in this age group, when exposure to different kinds of stressors may result in body weight and metabolic changes.

    Australian didgeridoo is a reed-less hollow conically shape wooden tubular wind instrument typically measuring up to 150 cm in length, with distal and proximal diameters ranging from 150 to 30 mm. This tube allows a player to produce only a narrow variety of sound and sounds effects because it is coupled directly to the player's vocal tract. The typical frequency of the tube typically called the drone, is approximately within 60 to 100 Hz range. This tone generation modulated by lip vibration is supported by circular breathing, allowing for an uninterrupted (indefinite) length of sound generation. Inhalation introduces sound pulsation, while specific tonal effects can be consciously created by manipulation of the player's lips and/or the vocal tract, including conscious phonation using vocal folds vibration, all used to enrich both the sound and the artistic meaning of the played sequence. Though the results of the research on the acoustics of this instrument are often reported in the literature, physiologic data regarding vocal tract configurations, and especially on the behavior of the vocal folds in regulation of ventilation and in phonation, remain less than underreported. The data presented here comprises (as far as we were able to determine) the first ever physiologic account of vocal fold activity in a didgeridoo player observed with help of trans-nasal endoscopy. Our focus was to reveal the work of t

    We predict the observational signatures of galaxy scale outflows powered by active galactic nuclei (AGN). Most of the emission is produced by the forward shock driven into the ambient interstellar medium (ISM) rather than by the reverse shock. AGN-powered galactic winds with energetics suggested by phenomenological feedback arguments should produce spatially extended ˜1-10 keV X-ray emission ˜ 1041-44 erg s- 1, significantly in excess of the spatially extended X-ray emission associated with normal star-forming galaxies. The presence of such emission is a direct test of whether AGN outflows significantly interact with the ISM of their host galaxy. We further show that even radio-quiet quasars should have a radio luminosity comparable to or in excess of the far-infrared-radio correlation of normal star-forming galaxies. This radio emission directly constrains the total kinetic energy flux in AGN-powered galactic winds. Radio emission from AGN wind shocks can also explain the recently highlighted correlations between radio luminosity and the kinematics of AGN narrow-line regions in radio-quiet quasars.

    The funds from this grant were used to support observations and analysis with the International Ultraviolet Explorer (IUE) satellite telescope. The main area of scientific research concerned the variability analyses of ultraviolet spectra of Active Galactic Nuclei, primarily quasars, Seyfert galaxies, and BL Lacertae objects. The Colorado group included, at various times, the P.I. (J.M. Shull), Research Associate Dr. Rick Edelson, and graduate students Jon Saken, Elise Sachs, and Steve Penton. A portion of the work was also performed by CU undergraduate student Cheong-ming Fu. A major product of the effort was a database of all IUE spectra of active galactic nuclei. This database is being analyzed to obtain spectral indices, line fluxes, and continuum fluxes for over 500 AGN. As a by-product of this project, we implemented a new, improved technique of spectral extraction of IUE spectra, which has been used in several AGN-WATCH campaigns (on the Seyfert galaxy NGC 4151 and on the BL Lac object PKS 2155-304).

    Background The literature indicates that medical practitioners experience declining empathy levels in clinical practice. This highlights the need to educate medical students about empathy as an attribute early in the academic curriculum. The objective of this study was to evaluate year one students’ self-reported empathy levels following a 2-hour empathy workshop at a large medical school in Malaysia. Methods Changes in empathy scores were examined using a paired repeated-measures t-test in this prospective before and after study. Results Analyzing the matched data, there was a statistically significant difference and moderate effect size between mean empathy scores before and 5 weeks after the workshop (112.08±10.67 versus 117.93±13.13, P<0.0001, d=0.48) using the Jefferson Scale Physician Empathy (Student Version). Conclusion The results of this observational study indicate improved mean self-reported empathy scores following an empathy workshop. PMID:24876799

    Microbial communities adapt to a wide range of pressures, temperatures, salinities, pH, and oxidation states. Although, significant attention has been focused on the effects of high and low temperature on physiology, there is some evidence that elevated pressure may also manifest interesting effects on cellular physiology, such as enzyme inactivation, cell-membrane breach, and suppression of protein interactions with various substrates. However, exactly how these factors affect intact cells is not well understood. In this study, we have adapted diamond anvil cells to explore the effects of high pressure on microbial life. We used the rate of microbial formate oxidation as a probe of metabolic viability. The utilization of formate by microorganisms is a fundamental metabolic process in anaerobic environments. We monitored in-situ microbial formate oxidation via molecular spectroscopy for Shewanella oneidensis strain MR1 and Escherichia coli strain MG1655 at high pressures (68 to 1060 MPa). At pressures of 1200 to 1600 MPa, living bacteria resided in fluid inclusions in ice-VI crystals and continued to be viable upon subsequent release to ambient pressures (0.1 MPa). Furthermore, direct microscopic observations indicate that these cells maintain their ability for cellular division upon decompression from such high pressures. Evidence of microbial viability and activity at these extreme pressures expands by an order of magnitude the range of conditions representing the habitable zone in the solar system. These results imply that pressure may not be a significant impediment to life. The maximum pressure explored in this work is equivalent to a depth of ~ 50 km below Earth's crust, or ~ 160 km in a hypothetical ocean. The pressures encountered at the depths of thick ice caps and deep crustal subsurface may not be a limiting factor for the existence of life. This suggests that deep (water/ice) layers of Europa, Callisto, or Ganymede, subduction zones on Earth, and the

    1976-01-01

    One hundred loops interconnecting 94 separate active solar regions detectable in soft X-rays were identified during the Skylab mission. While close active regions are commonly interconnected with loops, the number of such interconnections decreases steeply for longer distances; the longest interconnecting loop observed in the Skylab data connected regions separated by 37 deg. Several arguments are presented which support the point of view that this is the actual limit of the size of magnetic interconnections between active regions. No sympathetic flares could be found in the interconnected regions. These results cast doubt on the hypothesis that accelerated particles can be guided in interconnecting loops from one active region to another over distances of 100 deg or more and eventually produce sympathetic flares in them.

    2013-04-01

    Soil Science can be considered a discipline that serves as a fundamental base for other disciplines such as ecology, agronomy, plant production, etc. In order to demonstrate the relevance and connection to real world it is important to develop field and practical activities. Field activities help student to comprehend soil as part of the landscape and the natural ecosystems. These activities also help them to realize the importance of historical soil use on the quality of todaýs soil and landscapes. It is well known that fieldwork practices are essential to strengthen the soil science knowledge of students and their learning process. These fieldwork practices involve doing a physical activity rather than passively attending lectures or watching demonstrations. The simple visual and tactile observations in the field could be used to predict soil behavior and these direct observations are best made in the field. Students who learned in the field using an active work are more motivated, have more positive attitudes, and place more value in their work than those that learn passively. Therefore, when scheduling the coursework an important time is assigned to field work, which sometimes is not sufficiently profited from the standpoint of student learning taking into consideration the economic effort involved. We are aware that part of the students are simple spectators in the field so we encourage their participation by making them responsible for obtaining part of the information about the place and the types of soils that will be visited. On the other hand, we will invite the students to do some game based exercises, which are fun and force them to work in groups and to pay attention to explanations. Our objective is to present the information in a more attractive way, making the learning of soil profile description and easier task. The exercises that we propose are both field and problem-based learning to make sure that the knowledge is more memorable (non

    2011-01-01

    We present a concept for a small satellite mission to make systematic, global observations of night-time lights with spatial resolution suitable for discerning the extent, type and density of human settlements. The observations will also allow better understanding of fine scale fossil fuel CO2 emission distribution. The NASA Earth Science Decadal Survey recommends more focus on direct observations of human influence on the Earth system. The most dramatic and compelling observations of human presence on the Earth are the night light observations taken by the Defence Meteorological System Program (DMSP) Operational Linescan System (OLS). Beyond delineating the footprint of human presence, night light data, when assembled and evaluated with complementary data sets, can determine the fine scale spatial distribution of global fossil fuel CO2 emissions. Understanding fossil fuel carbon emissions is critical to understanding the entire carbon cycle, and especially the carbon exchange between terrestrial and oceanic systems.

  20. Kinematic observers for active control of helicopter rotor vibration

    NASA Technical Reports Server (NTRS)

    Mckillip, Robert M., Jr.

    1986-01-01

    A simple scheme for estimating the state variables of a helicopter rotor is presented. The method incorporates the use of blade-mounted accelerometers and/or position transducers to reconstruct modal displacements and velocities. The design of the observer structure and feedback gains is simplified by the fact that the method requires only knowledge of basic kinematic relationships between the various modal quantities. The observer structure described is particularly well-suited to control problems where the use of a traditional Kalman Filter approach would be too complex or costly. The technique can be viewed as decreasing the requirements on observer complexity while increasing the need for an enhanced sensor complement.

  1. Observations of Lower Thermospheric Nitric Oxide from the Student Nitric Oxide Explorer

    NASA Astrophysics Data System (ADS)

    Bailey, S. M.

    2004-12-01

    The production of nitric oxide is a key response of the upper atmosphere to solar energy deposition. NO plays a strong role in the thermospheric energy balance as it emits efficiently in the infrared, it is the terminal ion in the lower ionosphere, and if transported to lower altitudes will catalytically destroy ozone. NO is primarily produced through the reaction of excited atomic nitrogen with molecular oxygen. One of the primary loss mechanisms of NO is photodissociation by solar ultraviolet irradiance. In order to produce the excited atomic nitrogen atom, the strong N2 molecular bond must be broken. At low latitudes, solar soft X-ray irradiance is the energy source that leads to NO. At high latitudes, auroral electrons and the energetic secondary electrons provide the source of energy that leads to the large amounts of NO observed there. Coupling between latitude regions may occur as high latitude NO is transported by winds to lower latitude. In this talk we describe observations of NO from the Student Nitric Oxide Explorer (SNOE). SNOE observed fluorescently scattered sunlight by NO at 215 and 237 nm to obtain global concentrations of NO in the lower thermosphere daily from February 1998 through December 2003. We will present case studies of the observed response to large auroral storms. In particular, the effects of the large storms of April 2002 and November 2003 will be presented. The SNOE observations show that auroral energy deposition produces a significant global effect on the upper atmosphere.

    2009-10-01

    This study examined cross-cultural differences in personal and behavioral determinants of vigorous-intensity and moderate-intensity physical activity (PA) among college students living in distinctly different cultures, that is, the United States, Costa Rica, India, and South Korea. Participants of this study were recruited from randomly chosen public universities in the 4 countries during the 2006-2007 academic year. A total of 4685 students participated in the study (response rate 90%). Vigorous-intensity PA was measured by asking on how many of the past 7 days the participants participated in PA for at least 20 minutes that made them sweat or breathe hard. For moderate-intensity PA, participants were asked on how many of the past 7 days they participated in PA for at least 30 minutes that did not make them sweat or breathe hard. Findings indicate that whereas perceived overweight and fruit and vegetable consumption are relatively culture-free predictors of PA, gender and TV/video watching are culture-specific predictors. Binge drinking was not predictive of meeting the vigorous-intensity and moderate-intensity PA guidelines in any of the 4 countries. PMID:19661101

    2011-01-01

    BACKGROUND This study was conducted to empirically evaluate specific human, curricular, and material resources that maximize student opportunities for physical activity during physical education (PE) class time. A structure-process-outcome model was proposed to identify the resources that influence the frequency of PE and intensity of physical activity during PE. The proportion of class time devoted to management was evaluated as a potential mediator of the relations between resource availability and student activity levels. METHODS Data for this cross-sectional study were collected from interviews conducted with 46 physical educators and the systematic observation of 184 PE sessions in 34 schools. Regression analyses were conducted to test for the main effects of resource availability and the mediating role of class management. RESULTS Students who attended schools with a low student-to-physical educator ratio had more PE time and engaged in higher levels of physical activity during class time. Access to adequate PE equipment and facilities was positively associated with student activity levels. The availability of a greater number of physical educators per student was found to impact student activity levels by reducing the amount of session time devoted to class management. CONCLUSION The identification of structure and process predictors of student activity levels in PE will support the allocation of resources and encourage instructional practices that best support increased student activity levels in the most cost-effective way possible. Implications for PE policies and programs are discussed. PMID:21087253

  14. Quantitative observations of cavitation activity in a viscoelastic medium.

    PubMed

    Collin, Jamie R T; Coussios, Constantin C

    2011-11-01

    Quantitative experimental observations of single-bubble cavitation in viscoelastic media that would enable validation of existing models are presently lacking. In the present work, single bubble cavitation is induced in an agar gel using a 1.15 MHz high intensity focused ultrasound transducer, and observed using a focused single-element passive cavitation detection (PCD) transducer. To enable quantitative observations, a full receive calibration is carried out of a spherically focused PCD system by a bistatic scattering substitution technique that uses an embedded spherical scatterer and a hydrophone. Adjusting the simulated pressure received by the PCD by the transfer function on receive and the frequency-dependent attenuation of agar gel enables direct comparison of the measured acoustic emissions with those predicted by numerical modeling of single-bubble cavitation using a modified Keller-Miksis approach that accounts for viscoelasticity of the surrounding medium. At an incident peak rarefactional pressure near the cavitation threshold, period multiplying is observed in both experiment and numerical model. By comparing the two sets of results, an estimate of the equilibrium bubble radius in the experimental observations can be made, with potential for extension to material parameter estimation. Use of these estimates yields good agreement between model and experiment. PMID:22088001

    This study was designed to characterize the quality and quantity of interactions between students and significant others in the processing of new information during classroom activities. I wanted to test the hypothesis that black children, from moderate to low income urban environments, tend to have a more socially active cognitive style than their white peers in the performance of classroom tasks. Five different English classes, all 8th graders in a single junior high school (total of 114 black and white boys and girls), were observed in the same environment at different intervals to identify differences in the number of interactions between boys and girls, by racial groups. Classroom lessons and related activities were videotaped. The recorded activity was tabulated and rated by 3 trained observers. Black children more than white, and boys more than girls, initiated interactions with peers in the classroom in performing assigned tasks. This social interaction also showed that (1) 76% of the observed classroom time, subjects as a group were observed on-task and (2) pupils' interactions with their selected targets (classmates and their teacher) were 87% positive, and (3) relatively few interactions could be classified as disruptive.

    [Purpose] This study examined sex differences in physical activity and social cognitive theory factors in Korean college students. [Subjects and Methods] A cross-sectional survey of 688 college students (285 men and 403 women) in Korea was conducted using a self-reported questionnaire. [Results] There was a significant difference in the level of physical activity between male and female students. The significant predictors of physical activity for male students were physical activity goals, physical activity self-efficacy, and sitting time. Meanwhile, those for female students were perceived weight, physical activity goal, physical activity outcome expectations, and sitting time. [Conclusion] Sex differences should be considered when developing interventions to increase physical activity. PMID:26180293

    Objectives. We determined the association between availability and quality of school health services and reproductive health outcomes among sexually active students. Methods. We used a 2-stage random sampling cluster design to collect nationally representative data from 9107 students from 96 New Zealand high schools. Students self-reported whether they were sexually active, how often they used condoms or contraception, and their involvement in pregnancy. School administrators completed questionnaires on their school-based health services, including doctor and nursing hours per week, team-based services, and health screening. We conducted analyses using multilevel models controlling for individual variables, with schools treated as random effects. Results. There was an inverse association between hours of nursing and doctor time and pregnancy involvement among sexually active students, with fewer pregnancies among students in schools with more than 10 hours of nursing and doctor time per 100 students. There was no association between doctor visits, team-based services, health screening, and reproductive health outcomes. Conclusions. School health services are associated with fewer pregnancies among students, but only when the availability of doctor and nursing time exceeds 10 hours per 100 students per week. PMID:22897539

    2011-08-01

    There are an increasing number of students with learning difficulties attending university, and currently much debate about the suitability and ability of students with dyslexia at both medical school and once they graduate into clinical practice. In this study we describe the performance of students with dyslexia compared to fellow students in extended matching questions (EMQ), short answer question (SAQ) and observed structured clinical examinations (OSCE) and discuss the implications of differences identified. End of year assessment results for 5 cohorts of medical students were analysed. Students with dyslexia did less well overall in all assessment types in year 1 but this difference was not evident in later years. Dyslexic students who were allowed extra time in written assessments did better than dyslexic students who did not have their assessment concessions in place. When station type within OSCE assessments was analysed students with dyslexia did less well in both examination skills and data interpretation stations in years 1, 2 & 3. In conclusion, differences in performance in written assessments are only evident early in training and may be partly due to delayed adjustment to medical school or implementation of assessment concessions. Performance in individual OSCE stations is dependent on station type. Why students with specific learning difficulties (SpLDs) perform less well in examination skills and data analysis OSCE stations requires further investigation. PMID:21249518

    Active participation in immersive simulation experiences can result in technical and non-technical skill enhancement. However, when simulations are conducted in large groups, maintaining the interest of observers so that they do not disengage from the learning experience can be challenging. We implemented Tag Team Simulation with the aim of ensuring that both participants and observers had active and integral roles in the simulation. In this paper we outline the features of this innovative approach and provide an example of its application to a pain simulation. Evaluation was conducted using the Satisfaction with Simulation Experience Scale. A total of 444 year nursing students participated from a population of 536 (response rate 83%). Cronbach's alpha for the Scale was .94 indicating high internal consistency. The mean satisfaction score for participants was 4.63 compared to 4.56 for observers. An independent sample t test revealed no significant difference between these scores (t (300) = -1.414, p = 0.16). Tag team simulation is an effective approach for ensuring observers' and participants' active involvement during group-based simulations and one that is highly regarded by students. It has the potential for broad applicability across a range of leaning domains both within and beyond nursing. PMID:25936431

    Objective: To merge scholarly activity into the curriculum developed for medical students electing a rotation in wound care and/or dermatology. Approach: The authors adapted the unique wound care curriculum developed for medical student rotators and residents to incorporate structured scholarly projects, opportunities for mentorship, and feedback for continued improvement. Results: Benefits have been observed to both students and to the clinic, as reflected by online survey results, increased productivity in the form of posters and manuscripts, and opportunities for professional networking. Discussion: Rotations and clerkships can be transformed from haphazard, bystander observational experiences to active participation that enhances comprehension and retention, while also providing benefits to preceptors. Innovation: Integration between research, education, and clinical activities in a structured way can provide opportunity for enhanced learning experiences and promote the concept of evidence-based practice. Conclusion: With observed benefits to students, researchers, and staff in this clinical setting, other clerkship rotation settings should consider an integrated and structured approach to learning, which includes scholarly activities. Further rigorous program evaluation is necessary to further quantify preliminary positive feedback regarding this approach. PMID:24804160

    2010-08-01

    The waveguide invariant in shallow water environments has been widely studied in the context of passive sonar. The invariant provides a relationship between the frequency content of a moving broadband source and the distance to the receiver, and this relationship is not strongly affected by small perturbations in environment parameters such as sound speed or bottom features. Recent experiments in shallow water suggest that a similar range-frequency structure manifested as striations in the spectrogram exists for active sonar, and this property has the potential to enhance the performance of target tracking algorithms. Nevertheless, field experiments with active sonar have not been conclusive on how the invariant is affected by the scattering kernel of the target and the sonar configuration (monostatic vs bistatic). The experimental work presented in this paper addresses those issues by showing the active invariance for known scatterers under controlled conditions of bathymetry, sound speed profile and high SNR. Quantification of the results is achieved by introducing an automatic image processing approach inspired on the Hough transform for extraction of the invariant from spectrograms. Normal mode simulations are shown to be in agreement with the experimental results. PMID:20707430

  19. Comparison of a thermospheric photochemical model with Student Nitric Oxide Explorer (SNOE) observations of nitric oxide

    NASA Astrophysics Data System (ADS)

    Barth, C. A.; Bailey, S. M.

    2004-03-01

    A time-dependent thermospheric model has been used to calculate the nitric oxide density in the lower thermosphere for a 935-day period, 11 March 1998 to 30 September 2000. This model uses daily values of the observed solar soft X-ray irradiance (2-7 nm) as an energy input parameter. The model does not include an energy input from auroral electron precipitation. The results of the model calculation of nitric oxide density at 110 km were compared with observations of nitric oxide density made with the Student Nitric Oxide Explorer (SNOE) for the 935-day period. At the equator the model calculations and the observations agree very well with a linear correlation coefficient of 0.876. The correlation coefficient remains high for the altitude region 107-117 km, the region where solar soft X-rays (2-7 nm) are the major source of nitric oxide production. The comparison of the model calculations with the observations as a function of latitude show that there is excess nitric oxide poleward of 30°N and S latitude particularly during the fall-winter season. We believe that the source of this excess nitric oxide is the nitric oxide that is produced in the auroral region (65°-75°N and S geomagnetic latitude) by precipitating auroral electrons. We believe that aurorally produced nitric oxide is transported equatorward by horizontal winds. At midlatitudes the excess nitric oxide decays to about half of its initial value in one day. At times of large geomagnetic storms we believe that aurorally produced nitric oxide is transported all the way to the equator by horizontal winds. The excellent correlation of the model calculations and the SNOE observations of nitric oxide at 110 km between 30°S and 30°N support the hypothesis that solar soft X-rays are the source of the variability of nitric oxide in the thermosphere at low latitudes.

  20. Kepler Observations of Rapid Optical Variability in Active Galactic Nuclei

    2012-01-01

    Over three quarters in 2010 - 2011, Kepler monitored optical emission from four active galactic nuclei (AGN) with approx 30 min sampling, > 90% duty cycle and approx < 0.1% repeatability. These data determined the AGN optical fluctuation power spectral density functions (PSDs) over a wide range in temporal frequency. Fits to these PSDs yielded power law slopes of -2.6 to -3.3, much steeper than typically seen in the X-rays. We find evidence that individual AGN exhibit intrinsically different PSD slopes. The steep PSD fits are a challenge to recent AGN variability models but seem consistent with first order MRI theoretical calculations of accretion disk fluctuations.

  1. C IV Doppler shifts observed in active region filaments

    NASA Technical Reports Server (NTRS)

    Klimchuk, J. A.

    1986-01-01

    The Doppler shift properties of 21 active region filaments were studied using C IV Dopplergram data. Most are associated with corridors of weak magnetic field that separate opposite polarity strong fields seen in photospheric magnetograms. A majority of the filaments are relatively blue shifted, although several lie very close to the dividing lines between blue and red shift. Only one filament in the samples is clearly red shifted. A new calibration procedure for Dopplergrams indicates that sizable zero point offsets are often required. The center-to-limb behavior of the resulting absolute Doppler shifts suggests that filament flows are usually quite small. It is possible that they vanish.

  2. Hinode Observations of an Eruption from a Sigmoidal Active Region

    NASA Astrophysics Data System (ADS)

    Green, L. M.; Wallace, A. J.; Kliem, B.

    2012-08-01

    We analyse the evolution of a bipolar active region which produces an eruption during its decay phase. The soft X-ray arcade develops high shear over a time span of two days and transitions to sigmoidal shortly before the eruption. We propose that the continuous sigmoidal soft X-ray threads indicate that a flux rope has formed which is lying low in the solar atmosphere with a bald patch separatrix surface topology. The formation of the flux rope is driven by the photospheric evolution which is dominated by fragmentation of the main polarities, motion due to supergranular flows and cancellation at the polarity inversion line.

    Latina and Latino American students are among the lowest achievers in science, when compared to European and Asian American students, and are highly underrepresented in science careers. Studies suggested that a part of this problem is students' lack of access to science, due to their status as English language learners and their perceived status as deficient students. This study investigated the social construction of science in a second grade dual language urban classroom that offered bilingual students access to science, while positioning them as competent, capable learners. What participants valued in science was interpreted from their stated beliefs and attitudes, as well as their patterned ways of reading, writing, and talking. A bilingual European American teacher and three Latina and Latino focal students were observed over the course of 10 weeks, as they enacted a science unit, in English, on habitats. Science lessons were videotaped, documented with field notes, and transcribed. Interviews with the teacher and students were audiotaped and transcribed, and relevant curriculum documents, and teacher- and student-generated documents, copied. Gee's (1999) d/Discourse analysis system was applied to the transcripts of science lessons and interviews as a way to understand how participants used language to construct situated activities and identities in science. Curriculum documents were analyzed to understand the positioning of the teacher and students by identifying the situated activities and roles recommended. Students' nonfiction writing and published nonfiction texts were analyzed for linguistic structures, semantic relationships and conventions of science writing. Results indicated that the teacher drew on traditional and progressive pedagogical practices that shaped her and her students' science activities and situated identities. The teacher employed traditional talk strategies to build science themes, while students enacted their roles as compliant

    Rapid changes in the nursing field and high demand for practicing nurses put pressure on nursing faculty to educate increasing numbers of nursing students, often without corresponding increases in resources. Although the use of active and cooperative instruction methods in the classroom has been associated with improved student learning, these practices require increased effort on the part of both faculty and students. In addition, little is known about whether these methods influence student nurses' use of these more elaborative processing strategies in their independent study. The purpose of this quasi-experimental investigation was to identify the impact of incorporating active and cooperative classroom instructional activities on student preference for teaching methods and use of learning strategies in independent study. A convenience sample of beginning baccalaureate nursing students at a large Mid-Atlantic University was randomly assigned by the registrar to two class sections. Students in one section received primarily active/cooperative instruction, while the other received primarily traditional lecture-based instruction. Results indicated that student nurses exposed to active/cooperative instructional methods had an increased preference for these methods after a semester of instruction, while those exposed to traditional instruction had a higher preference for traditional methods. In addition, students participating in active class instruction reported increased preference for more elaborative independent study strategies, although overall preference for both groups indicated a reliance on surface study strategies of memorization and recall. Implications for use of instruction and student testing methodologies are presented. PMID:17030077

    Wintertime polynyas, or semipermanent open water areas, occur adjacent to the Antarctic coast in response to strong, offshore katabatic winds and are sites for rapid surface ice formation, brine rejection, and formation of High Salinity Shelf Water (HSSW) that contributes to Antarctic deep and bottom waters. We report on a time series of CTD and microstructure profiles obtained from the Mertz Glacier Polynya, Antarctica over a 5- hour period during October (late austral winter) 2004. Winds were offshore at ~5 ms-1 during the observations, and air temperatures were <-10° C. These conditions directly followed cessation of much stronger 20-25 ms-1 winds at the same low temperatures. The upper layer was initially vertically homogeneous to ~140 m depth. During the next 4 h it deepened to ~250 m before beginning to shoal. During this time multiple salinity-stratified layers developed through which temperature remained effectively at the freezing point. Salinity increase in this layer was consistent with ~4 cm new ice formation over the 5-hour duration of the observations; however, we ascribe much of the upper layer evolution to lateral advective processes. Vertical eddy diffusivity Kz, computed from shear microstructure, exhibited pronounced maxima above and below the interface underlying the upper layer, and also in association with the evolving upper layer salinity structures. Values of Kz within these maxima often exceeded 5x10-3 m2s-1. We will address the relative contributions of current shear, convective turbulence and advection to upper-ocean evolution in the polynya and discuss the relevance of these results to regionally significant processes such as formation of HSSW.

    In this paper we present initial information concerning a new direct observation system-the Observational System for Recording Physical Activity in Children-Preschool Version. The system will allow researchers to record young children's physical activity levels while also coding the topography of their physical activity, as well as detailed indoor and outdoor social and nonsocial contextual information. With respect to interobserver agreement (IOA), the kappa and category-by-category agreement mean of those obtained for the three illustrative preschools were generally above .80. Hence, our IOA data indicated that trained observers in the three preschools frequently agreed on the eight observational categories and accompanying codes. The results for preschoolers' level of physical activity indicated they spent the majority of observational intervals in sedentary activity (i.e., more than 80% intervals) and were observed in moderate to vigorous physical activity much less frequently (i.e., 5% or fewer intervals). For the 15 indoor and 12 outdoor activity contexts, variability across both the activity contexts and the three preschools were evident. Nevertheless, three classroom contexts-transition, snacks, and naptime--accounted for the greatest porportion of coded activity contexts for the children. In the three preschools, 4 of 17 physical activity types--sit and squat, lie down, stand, and walk--accounted for the topography of much of children's physical activity behavior Systematic observation of more representative preschool samples might better inform our present understanding of young children's physical activity in community preschool programs.

    Over three quarters in 2010-2011, Kepler monitored optical emission from four active galactic nuclei (AGNs) with {approx}30 minute sampling, >90% duty cycle, and {approx}<0.1% repeatability. These data determined the AGN optical fluctuation power spectral density (PSD) functions over a wide range in temporal frequency. Fits to these PSDs yielded power-law slopes of -2.6 to -3.3, much steeper than typically seen in the X-rays. We find evidence that individual AGNs exhibit intrinsically different PSD slopes. The steep PSD fits are a challenge to recent AGN variability models but seem consistent with first-order magnetorotational instability theoretical calculations of accretion disk fluctuations.

    It is well-known that musicians are at risk for music-induced hearing loss, however, systematic evaluation of music exposure and its effects on the auditory system are still difficult to assess. The purpose of the study was to determine if college students in jazz band-based instructional activity are exposed to loud classroom noise and consequently exhibit acute but significant changes in basic auditory measures compared to non-music students in regular classroom sessions. For this we (1) measured and compared personal exposure levels of college students (n = 14) participating in a routine 50 min jazz ensemble-based instructional activity (experimental) to personal exposure levels of non-music students (n = 11) participating in a 50-min regular classroom activity (control), and (2) measured and compared pre- to post-auditory changes associated with these two types of classroom exposures. Results showed that the L eq (equivalent continuous noise level) generated during the 50 min jazz ensemble-based instructional activity ranged from 95 dBA to 105.8 dBA with a mean of 99.5 ± 2.5 dBA. In the regular classroom, the L eq ranged from 46.4 dBA to 67.4 dBA with a mean of 49.9 ± 10.6 dBA. Additionally, significant differences were observed in pre to post-auditory measures between the two groups. The experimental group showed a significant temporary threshold shift bilaterally at 4000 Hz (P < 0.05), and a significant decrease in the amplitude of transient-evoked otoacoustic emission response in both ears (P < 0.05) after exposure to the jazz ensemble-based instructional activity. No significant changes were found in the control group between pre- and post-exposure measures. This study quantified the noise exposure in jazz band-based practice sessions and its effects on basic auditory measures. Temporary, yet significant, auditory changes seen in music students place them at risk for hearing loss compared to their non-music cohorts. PMID:23771423

    How the continents deform remains a matter of debate. One view postulates that continental deforming zones are comprised of a limited numbers of rigid (elastic) microplates. If true, the surface motion can then be described by the relative rotation of blocks, and strain should be localized along the major faults separating the blocks. An alternative view is that the deformation at depth is distributed over wide areas, can be modelled by a viscous flow responding to boundary conditions applied on it and gravitational potential energy gradients related to variations in topography, and the surface strain simply reflects this deformation. Western Turkey is a region of crustal extension, part of the Nubia/Eurasia plate boundary. Its kinematics is often modelled by the relative motion of a small number of rigid blocks (Nyst & Thatcher, 2005, Reilinger et al., 2006). However, until now, the limited number of GPS velocity vectors available has prevented a detailed examination of which is the more appropriate description. We present a new geodetic velocity field including ~100 sites from the longitude the Central Anatolian plateau to the Aegean coast, derived from a combination of campaigns carried out between 1997 and 2006, and continuous GPS operating since 2003, which we use to test the different models. While the kinematics of the area can be correctly modelled by a block model, a good fit to the velocity field requires blocks with sizes smaller than 100 km and still fails to adequately predict the strain rate observed within blocks . Alternatively, we test an approach where the lithosphere is modelled as a thin viscous sheet, responding to the gravitational potentiel energy contrast between the high plateau of eastern Turkey to the east and the subduction along the Hellenic trench in the southwest. The simplistic model has only one free parameter (the force applied by the subducting oceanic lithosphere on the Aegean ), but provides a good agreement with the observed

    This study examined student-reported participation in school food and nutrition activities in Vancouver, British Columbia (BC), and whether engagement differed by gender and between elementary and secondary school students. A cross-sectional survey of grade 6-8 public school students (n = 937) from 20 elementary and 6 secondary schools assessed student-reported participation in a range of food and nutrition activities. Statistical analyses included descriptive statistics and multilevel logistic regression to examine associations between participation with gender and school type. Overall, <50% of students reported engaging in most of the food and nutrition activities examined in the 2011-2012 school year, including: food preparation (36%), choosing/tasting healthy foods (27%), learning about Canada's Food Guide (CFG) (45%), learning about foods grown in BC (35%), gardening (21%), composting (32%), and recycling (51%). Females were more likely to report recycling and learning about CFG and BC-grown foods (P < 0.05). Secondary students were more likely to report activities focused on working with or learning about food/nutrition (P < 0.05). Despite local and provincial efforts to engage students in food and nutrition experiences, participation in most activities remains relatively low, with few students exposed to multiple activities. Continued advocacy is needed from the dietetics community to improve student engagement in food and nutrition activities. PMID:27182726

    Scientific split-beam echosounders are sensitive instruments for observing biomass densities and individual behaviour. Earlier studies have demonstrated that these instruments can be used to study diving behaviour of cetaceans. In this paper, we go into more detail about the recorded signal to see if and how acoustic split-beam data can be used to extract information about synchronous behaviour and other species related characteristics. Data of several cetacean individuals were collected by a moored echosounder pinging upwards from about 900 m in the Charlie Gibbs Fracture Zone. In this paper, we discuss methodological issues associated with using split-beam tracking of large marine animals. Further we demonstrate that target tracking of cetaceans can be used to study solo dives as well as behavioural synchrony. We also show that paired signals can easily be interpreted as false synchrony due to the size of the animals. In such cases a rough estimate of the diameter, and hence size, of the animals can be estimated. We emphasise on four examples that clarify methodological challenges including synchronous swimmers as well as large single cetaceans that might be interpreted as two synchronous swimmers. The applied technology requires that the animals remain in a narrow acoustic beam for long enough time to extract behavioural information. The technology can be improved by developing automatic tracking of cetaceans with a steerable transducer. This will substantially increase the search volume and enable tracking of cetaceans over longer periods and thus, produce more realistic information about the whale behaviour.

    Aminoglycoside-class antibiotics bind directly to ribosomal RNA, imparting pleiotropic effects on ribosome function. Despite in-depth structural investigations of aminoglycoside–RNA oligonucleotide and aminoglycoside-ribosome interactions, mechanisms explaining the unique ribosome inhibition profiles of chemically similar aminoglycosides remain elusive. Here, using single-molecule fluorescence resonance energy transfer (smFRET) methods, we show that high-affinity aminoglycoside binding to the conserved decoding site region of the functional pre-translocation ribosome complex specifically remodels the nature of intrinsic dynamic processes within the particle. The extents of these effects, which are distinct for each member of the aminoglycoside class, strongly correlate with their inhibition of EF-G–catalyzed translocation. Neomycin, a 4,5-linked amino-glycoside, binds with lower affinity to one or more secondary binding sites, mediating distinct structural and dynamic perturbations that further enhance translocation inhibition. These new insights help explain why closely related aminoglycosides elicit pleiotropic translation activities and demonstrate the potential utility of smFRET as a tool for dissecting the mechanisms of antibiotic action.

    As a community health education center affiliated with an academic institution, we recognize that by investing in the professional development of our students, we not only maximize our own outcomes but those of our students as well. Our project, Creating Community Connections, was developed to aid the work of our Center in characterizing the evolving community landscape following Hurricane Katrina while providing opportunities for students to engage in experiential learning. Students in the project could gain skills in program planning and community assessment, as well as leadership and communications. Twenty-three students worked on the project during its 2 years, developing data collection tools, organizing and conducting key informant interviews, facilitating focus groups and community forums, managing data, and summarizing project findings for community presentations. Participation in this project allowed our students to grow as public health leaders and researchers while gaining a greater appreciation for community collaboration. PMID:21617412
