<p>The Earth’s magnetic field is especially dynamic at high latitudes.  The most awesome manifestation of this is certainly the aurora borealis or northern lights – caused by the interaction of the solar wind with the Earth’s magnetic field.  Aside from the aurora you can’t see these magnetic variations.  But your phone can.  Virtually every modern smartphone is equipped with a 3-component magnetometer to enable the compass pointing capability for navigation.  CrowdMag is a popular NOAA/CIRES citizen science app that we developed to tap into your smartphone’s magnetometer.  It lets you interact with the Earth’s magnetic field.</p><p>The purpose of this presentation is to highlight the possibilities for using CrowdMag for science outreach and engagement, particularly in Arctic regions where day-to-day magnetic variations can exceed hundreds of nano-Teslas.  We will show example projects that were carried out by summer interns as part of the University of Colorado’s “Research Experience for Community College Students” (RECCS) program.  CrowdMag can be used to carry out various simple experiments for mapping and investigating the Earth’s magnetic field.  We seek input and collaboration with others interested in Citizen Science and outreach in Arctic regions.   </p>

At the University of Colorado, Boulder, a new program designed to link graduate students with 1st and 2nd year undergraduate students through engineering research projects and mentoring relationships was initiated in Spring 2011. Your Own Undergraduate Research Experience at the University of Colorado (YOU’RE@CU) has three main goals: (1) increase retention of undergraduate students in engineering, particularly women and underrepresented minorities (URMs); (2) excite undergraduate student interest in research projects and future careers in academia or industry; (3) provide graduate students with training and hands-on mentoring experience with the expectation that this will positively influence graduate student choices to seek a career in academia. This paper illustrates the details of the YOU’RE@CU program during its pilot implementation in Spring 2011. The assessment strategy and methods are also explained, with presentation of qualitative data and discussion of the overall data analysis process.

<p>The Cassini spacecraft spent more than 13 years in the dusty environment of Saturn. During this long period of investigations of the Saturn magnetosphere, the RPWS (Radio Plasma Wave Science) instrument recorded more than half a million spiky signatures. However, not all of them can be interpreted as dust impact signals because plasma structures like solitary waves can result in similar pulses.</p><p>We select the registered spike waveforms recorded by both dipole and monopole configurations of electric field antennas operated in 10 kHz or 80 kHz sampling rates at the distance of 0.2 Rs around the rings mid-plane. These waveforms were corrected using Cassini WBR (Wide Band Receiver) transfer function to obtain the correct shape of the signal. The signal polarity, amplitude, and timescales of different parts of the waveforms were quantitatively inspected according to the spacecraft potential, the density of the ambient plasma, the intensity of the Saturn’s magnetic field, and its orientation with respect to the spacecraft. The magnetic field orientation was also used for distinguishing between signals resulting from dust impacts and signals produced by solitary waves misinterpreted as dust impact signals.</p><p>The preliminary results of our study indicate similarities with previous laboratory studies of dust impact waveforms on the reduced model of Cassini bombarded with submicron-sized iron grains in external magnetic fields at the LASP facility of the University of Colorado. The polarity of the signals changes in accordance with a polarity of the spacecraft potential and pre-spike signals are also observed. The core of the paper is devoted to the relation between characteristics of dust impact signals and local plasma parameters and magnetic field intensity at the radial distance from 2 Rs to 60 Rs from Saturn surface.</p>

A new 1-MeV transmission electron microscope (Model JEM-1000) was installed at the Department of Molecular, Cellular and Developmental Biology of the University of Colorado in Boulder during the summer and fall of 1972 under the sponsorship of the Division of Research Resources of the National Institutes of Health. The installation was completed in October, 1972. It is installed primarily for the study of biological materials without many of the limitations hitherto unavoidable in standard transmission electron microscopy. Only the technical characteristics of the installation are briefly reviewed here. A more detailed discussion of the experimental program under way is being published elsewhere.

This report highlights some of the major developments in the area of speech anatomy and physiology drawing from the author's own research experience during his years at the University of Iowa and the University of Illinois. He has benefited greatly from mentors including Professors James Curtis, Kenneth Moll, and Hughlett Morris at the University of Iowa and Professor Paul Lauterbur at the University of Illinois. Many colleagues have contributed to the author's work, especially Professors Jerald Moon at the University of Iowa, Bradley Sutton at the University of Illinois, Jamie Perry at East Carolina University, and Youkyung Bae at the Ohio State University. The strength of these researchers and their students bodes well for future advances in knowledge in this important area of speech science.

This workshop will create a space for discussion on environmental politics and its impact on design for sustainable transitions. It will help participants identify different sustainability discourses; create a space for reflection on how these discourses influence design practice; and consider the environmental and social implications of different discourses. The workshop will do this work by encouraging knowledge sharing, reflection and interpretative mapping in a participatory space where individuals will create their own discourse maps. This work is informed by my research “Mapping Climate Communication” conducted at the Centre for Science and Technology Policy Research (CSTPR) in the Cooperative Institute for Environmental Sciences (CIRES), the University of Colorado, Boulder. With this research project I developed a discourse mapping method based on the discourse analysis method of political scientists and sustainability scholars. Using my own work as an example, I will facilitate a process that will enable participants to create new discourse maps reflecting their own ideas and agendas.
