Report on the Second Catalog Interoperability Workshop

The events, resolutions, and recommendations of the Second Catalog Interoperability Workshop, held at JPL in January, 1988, are discussed. This workshop dealt with the issues of standardization and communication among directories, catalogs, and inventories in the earth and space science data management environment. The Directory Interchange Format, being constructed as a standard for the exchange of directory information among participating data systems, is discussed. Involvement in the Interoperability effort by NASA, NOAA, ISGS, and NSF is described, and plans for future interoperability considered. The NASA Master Directory prototype is presented and critiqued and options for additional capabilities debated

The formation of arcs in the dynamic spectra of Jovian decameter bursts

A model is presented that can account for several features of the dynamic spectral arcs observed at decameter wavelengths by the planetary radio astronomy experiment on Voyagers 1 and 2. It is shown that refraction of an extraordinary mode wave initially excited nearly orthogonal to the local magnetic field is significantly influenced by the local plasma density, being greater the higher the density. It is assumed that the source of the decameter radiation lies along the L = 6 flux tube and that the highest frequencies are produced at the lowest altitudes, where both the plasma density and magnetic field gradients are largest. It is further assumed that the decameter radiation is emitted into a thin conical sheet, consistent with both observation and theory. In the model the emission cone angle of the sheet is chosen to vary with frequency so that it is relatively small at both high and low frequencies, but approximately 80 deg at intermediate frequencies. The resulting emission pattern as seen by a distant observer is shown to resemble the observed arc pattern. The model is compared and contrasted with examples of Voyager radio data

Guided Online Coaching for Teachers of Emergent Bilinguals in a TESOL Practicum Course During COVID-19

Guided online coaching for teachers of emergent bilinguals (EBLs) is a job-embedded professional development model established from the educational policies and practices described in the No Child Left Behind Act and Every Student Succeeds Act. Having effective teachers who ensure an equitable, creative, and linguistically and culturally relevant education for all EBLs is of paramount importance in the ever-changing demography of schools in the United States. The guided online coaching for teachers of EBLs offers a collaborative, facilitative, dialogic, and reflective coaching process for positively influencing teacher transformation, thus providing a creative language teaching pedagogy for EBLs. The purpose of this study was to understand and describe teachers’ transformation into creative and effective language teachers of EBLs through reflection and self-directed learning as well as coaches’ perception of the influence of the coaching process on those teachers’ professional growth during COVID-19. Two research questions guided this qualitative study: (1) How did 4 inservice teachers transform their teaching for EBLs when following the modified cyclic guided online coaching in a TESOL practicum course due to COVID 19? (2) How did 3 coaches perceive the influence of the guided online coaching model in terms of its transformation of the participating teachers? The participants in the qualitative case study included three coaches and four inservice teachers from racially, linguistically, culturally, and geographically diverse school settings in the Midwest. Among the data sources used were coach, peer, and instructor feedback and teacher reflections on two VoiceThread presentations from the three modified guided online coaching cycles (preparation, strategies, and reflection), the coaches’ semistructured interviews, and the teachers’ final paper for triangulating the data. Four themes emerged from the findings: Funds of Knowledge, EBL strategies, translanguaging, and evidence-based reflection. The results suggested cyclic guided online coaching for teachers of EBLs was a critical process for professional learning and transforming teachers’ creative and LCRC teaching

The Radio Jove Project

The Radio love Project is a hands-on education and outreach project in which students, or any other interested individuals or groups build a radio telescope from a kit, operate the radio telescope, transmit the resulting signals through the internet if desired, analyze the results, and share the results with others through archives or general discussions among the observers. Radio love is intended to provide an introduction to radio astronomy for the observer. The equipment allows the user to observe radio signals from Jupiter, the Sun, the galaxy, and Earth-based radiation both natural and man-made. The project was started through a NASA Director's Discretionary Fund grant more than ten years ago. it has continued to be carried out through the dedicated efforts of a group of mainly volunteers. Dearly 1500 kits have been distributed throughout the world. Participation can also be done without building a kit. Pre-built kits are available. Users can also monitor remote radio telescopes through the internet using free downloadable software available through the radiosky.com website. There have been many stories of prize-winning projects, inspirational results, collaborative efforts, etc. We continue to build the community of observers and are always open to new thoughts about how to inspire the observers to still greater involvement in the science and technology associated with Radio Jove

A beaming model of the Io-independent Jovian decameter radiation based on multipole models of the Jovian magnetic field

A geometrical model is presented in which the apparent source locations of the Io-independent decameter radiation are computed. The calculations assume that the radiation is produced by stably trapped electrons radiating near the electron gyrofrequency and that the emission is then beamed onto a conical surface. The maximum occurrence probability of noise storms is associated with regions in the Jovian magnetosphere where the axis of the emission cone is most inclined toward the Jovian equatorial plane. The calculations utilize and compare two of the octupole spherical harmonic expansions of the Jovian magnetic field constructed from data accumulated by the fluxgate and vector helium magnetometers on board Pioneer 11

Unpacking preservice agriculture teacher development through reflective awareness of stress: a mixed methods study

This mixed methods study used reflective awareness of stress to unpack preservice agriculture teacher development from the perspective of a teacher educator. Quantitative physiological stress data was collected using heart rate variability (HRV) to indicate stress levels experienced by eight senior preservice agricultural educators in their final semester prior to student teaching. Stress was measured during two microteaching experiences and qualitative follow-up interviews were used to add context to the quantitative data. Quantitative stress profiles were developed for each individual resulting in three profile groupings: low, medium, and high stress groups. Qualitative data were analyzed through the filter of the stress level groupings with thirteen themes emerging. Recommendations for teacher educators and for further research were provided

Automaticity in early visual processing: ages ten to sixty

A priming paradigm and a paradigm requiring apparent duration judgments for tachistoscopic presentations were used to provide converging tests for prerecognition automatic semantic access and to investigate developmental changes in early processing. Subjects from four different age groups (fifth and sixth graders, college age, thirty year olds, fifty year olds) participated in each of the two experiments. In the priming task, prime stimuli were presented tachistoscopically for durations which had previously shown, for individual subjects, chance level detection of stimulus presence versus absence. In the duration judgment task, stimulus exposure durations were, for each age group, the means of the duration for chance level presence-absence detection;The priming paradigm did not provide evidence for automatic semantic facilitation for any age group. The data suggested a need to more clearly differentiate between a global lexical and a specific semantic access to long term memory. Prerecognition processing was evident in two age groups in the apparent duration experiment, although the specific effects of lexical and semantic parameters differed from previous findings. Developmental differences were evident only in the presence-absence detection thresholds; the other tasks did not reveal age-related changes

Decameter: Wave radio observations of Jupiter during the 1970 apparition

Observations of Jupiter's sporadic decameter wavelength radio emissions were obtained between November 1978 and March 1979. A multistation, global network of monitoring instruments were utilized in order to obtain nearly continuous, synoptic observations of the planet. Observations were obtained daily at frequencies of 16.7 and 22.2 MHz using five element Yagi antennas at each end of a two element interferometer

Central On-Line Data Directory

The National Space Science Data Center (NSSDC) Central On-Line Data Directory (CODD), which allows the general scientist remote access to information about data sets available not only at NSSDC, but throughout the scientific community, is discussed. A user may search for data set information within CODD by specifying spacecraft name, experiment name, investigator name, and/or keywords. CODD will include information on atmospheric science data sets contained not only within the PCDS, but also within other data sets that are deemed important. Keywords to be used in locating these data sets are currently being formulated. The main type of keyword to be used for categorization of data sets will be discipline related. The primary discipline keyword for PCDS-type data sets would be ATMOSPHERIC SCIENCE. A good set of subdiscipline keywords is needed under this discipline to subdivide the data sets. A sheet containing a strawman set of subdiscipline keywords was distributed, and a request was made for the knowledgeable scientists to modify or replace the proposed keywords
