Surface elevation changes near Barrow (Alaska) measured using reflected GPS signals
No full textWe use reflected GPS signals to measure temporal changes of ground surface elevation due to dynamics of the active layer and near-surface permafrost. Applying the GPS interferometric reflectometry technique to the multipath signal-to-noise ratio data collected by a continuously-operating GPS receiver mounted deep in permafrost in Barrow, Alaska, we can retrieve the vertical distance between the antenna and reflecting surface. Using this unique kind of observables, we obtain daily changes of surface elevation during July and August from 2004 to 2015. Our results show distinct temporal variations at three timescales: regular thaw settlement within each summer, strong inter-annual variability that is characterized by a sub-decadal subsidence trend followed by a brief uplift trend, and a secular subsidence trend of 0.26 cm/year during 2004 and 2015

E-readers and adolescent engagement: a formative design experiment
No full textIntroduction As the use of e-readers becomes commonplace and more affordable, they will make their way into the hands of students. This research provides information about how the devices might be used as a tool to improve adolescent students‘ reading engagement and also helps to identify the struggles and pitfalls educators may face in implementing classroom use of e-readers. Purpose of the Study This study investigated how the use of dedicated electronic reading devices could be implemented as an intervention in an eighth grade language arts classroom to improve students‘ reading engagement. Methods and Procedures Six students from an eighth grade, heterogeneous class in a sizeable suburban middle school in a large, regional district participated in formative design experiment (Reinking & Bradley, 2008). Quantitative and qualitative data were collected prior to and after implementation of the e-reader intervention to determine a baseline of the students‘ reading engagement and to assess any changes. Additionally, qualitative data were collected throughout the intervention. Quantitative data were analyzed using a pairedsamples t-test for the following measures: Reading Engagement Index (Guthrie et al., 2007), Adolescent Motivation to Read Profile (Pitcher et al., 2007), Metacognitive Awareness of Reading Strategies Inventory (Mokhtari& Reichard, 2002) and The Motivations for Reading Questionnaire (Wigfield & Guthrie, 1997). Qualitative data were coded for recurring themes derived from the following sources: classroom observation and field notes, teacher reflective journal, student and intervention specialist interviews and student written reflections. Results and Discussion Analyses revealed that using an e-reader for assigned school reading had a positive impact on aspects of students reading engagement. Classroom implications, unanticipated effects and changes to the educational environment are also discussed.Ed. D.Includes bibliographical referencesby Kristine Lynch Shurin
Particle panic!: how popular media and popularized science feed public fears of particle accelerator experiments
No full textFrom novels and short stories to television and film, popular media has made a cottage industry of predicting the end of the world will be caused by particle accelerators. Rather than allay such fears, public pronouncements by particle scientists themselves often unwittingly fan the flames of hysteria. This book surveys media depictions of particle accelerator physics and the perceived dangers these experiments pose. In addition, it describes the role of scientists in propagating such fears and misconceptions, offering as a conclusion ways in which the scientific community could successfully allay such misplaced fears through more effective communication strategies. The book is aimed at the general reader interested in separating fact from fiction in the field of high-energy physics, at science educators and communicators, and, last but not least, at all scientists concerned about these issues. About the Author Kristine M Larsen holds a Ph.D. in Physics and is currently a professor at Central Connecticut State University, New Britain, CT, in the Geological Sciences Department. She has published a number of books, among them The Women Who Popularized Geology in the 19th Century (Springer, 2017), The Mythological Dimensions of Neil Gaiman (eds.

Recipient of the Gold Medal for Science Fiction/Fantasy in the 2012 Florida Publishing Association Awards), The Mythological Dimensions of Doctor Who (eds.

Response of the Ionosphere-Plasmasphere System to Periodic Forcing
No full textThe role of different mechanisms for generating periodic variability in the ionosphere and plasmasphere is studied in this dissertation. The impact of vertically propagating waves of lower atmospheric origin on introducing periodic spatial and temporal variability in the ionosphere and plasmasphere is first investigated. This is comprised of several different aspects. Initial focus is on the seasonal, local time, and altitude dependence of longitude variations due to nonmigrating tides in the F-region and topside ionosphere/plasmasphere using a combination of observations and numerical models. This is facilitated by the development of a new method for mitigating the effect of multipath on low-Earth orbit (LEO) satellite Global Positioning System (GPS) observations. The impact of large-scale changes in tropospheric convection due to the El-Nino Southern Oscillation on the ionosphere is also explored observationally. The influence of nonmigrating tides on the global ionosphere is revealed through study of the longitude variations in the solar quiet current system. Periodic temporal variability in the ionosphere due to planetary waves originating in the lower atmosphere is also investigated. The response of the global ionosphere to the quasi-16 day planetary wave is first presented. This is followed by observational evidence demonstrating that the nonlinear interaction between planetary waves and tides is the primary mechanism responsible for low-latitude ionospheric variability during sudden stratospheric warmings. Periodic temporal variability in the ionosphere and plasmasphere of solar origin is also studied. During the declining phase of solar cycle 23, near-Earth geospace was routinely disturbed due to high-speed solar wind streams emanating from solar coronal holes. The nature of the coronal holes was such that the Earth's upper atmosphere exhibited periodic behavior due to recurrent geomagnetic activity. A study of the latitude and local time response of the ionosphere to recurrent geomagnetic activity is performed herein. A method for estimating the location of the plasmapause from LEO GPS observations is also developed and applied to study periodic oscillations in the plasmapause
The decadal reflector heights for SG27 in Barrow, Alaska (2007-2016)
No full textReflector height, the distance between the receiver antenna phase center and ground surface, are derived from the SNR data using GPS-IR.The data are stored in the text format with four column (year , day of year, reflector height, uncertainty) year by year. The reflector heights span from year 2007 to 2016, whose changes are opposite to the changes of ground surface
