This project has been part of our lives for a long time. It began in 2011 when all the editors were working at the Michigan State University (MSU) Writing Center, Trixie Smith as the director and the rest of us as graduate students. Every day we found ourselves grappling with issues and ideas connected to graduate writers through our work at the writing center: working one-to-one with graduate writers, facilitating graduate writing groups, and offering workshops for graduate students, such as our Navigating the Ph.D. workshop series. The work was also personally relevant to most of us since we were graduate students at the time, frequently finding ourselves experiencing imposter syndrome and letting our identities as graduate students consume our lives. Little did we-excepting Trixie, perhaps-know then that our interest in graduate writing would intensify when we became junior faculty and found that we still faced many of the same writing-related concerns that we did as graduate students.Our motivations for developing this edited collection on graduate writing across the disciplines began when we turned from interacting with graduate writers to researching graduate writers and graduate writing. When the Writing, Rhetoric, and American Cultures department at MSU began an initiative to create research clusters that bring faculty, staff, and students together to engage in conducting academic research and developing publications, we decided that a research cluster focusing on graduate writing would be ideal. We participated in this Graduate Writing Research Cluster for the two years that we were all still at MSU and continued to collaborate when we began moving into faculty positions outside of MSU. Our collaboration culminated in a special issue of Across the Disciplines and this edited collection. What

A capability for measuring the thermal conductivity of microelectromechanical systems (MEMS) materials using a steady state resistance technique was developed and used to measure the thermal conductivities of SUMMiT TM V layers. Thermal conductivities were measured over two temperature ranges: 100K to 350K and 293K to 575K in order to generate two data sets. The steady state resistance technique uses surface micromachined bridge structures fabricated using the standard SUMMiT fabrication process. Electrical resistance and resistivity data are reported for poly1-poly2 laminate, poly2, poly3, and poly4 polysilicon structural layers in the SUMMiT process from 83K to 575K. Thermal conductivity measurements for these polysilicon layers demonstrate for the first time that the thermal conductivity is a function of the particular SUMMiT layer. Also, the poly2 layer has a different variation in thermal conductivity as the temperature is decreased than the poly1-poly2 laminate, poly3, and poly4 layers. As the temperature increases above room temperature, the difference in thermal conductivity between the layers decreases. 4 ACKNOWLEDGMENTSThe authors thank Rosemarie Renn and Katie Francis for assistance during the design of the thermal conductivity test structures and the Microelectronics Development Lab staff for their efforts in fabricating the structures.

Electromechanical impedance is a popular diagnostic method for assessing structural conditions at high frequencies. It has been utilized, and shown utility, in aeronautic, space, naval, civil, mechanical, and other types of structures. By contrast, fiber optic sensing initially found its niche in static strain measurement and low frequency structural dynamic testing. Any low frequency limitations of the fiber optic sensing, however, are mainly governed by its hardware elements. As hardware improves, so does the bandwidth (frequency range * number of sensors) provided by the appropriate enabling fiber optic sensor interrogation system. In this contribution we demonstrate simultaneous high frequency measurements using fiber optic and electromechanical impedance structural health monitoring technologies.A laboratory specimen imitating an aircraft wing structure, incorporating surfaces with adjustable boundary conditions, was instrumented with piezoelectric and fiber optic sensors. Experiments were conducted at different structural boundary conditions associated with deterioration of structural health. High frequency dynamic responses were collected at multiple locations on a laboratory wing specimen and conclusions were drawn about correspondence between structural damage and dynamic signatures as well as correlation between electromechanical impedance and fiber optic sensors spectra. Theoretical investigation of the effect of boundary conditions on electromechanical impedance spectra is presented and connection to low frequency structural dynamics is suggested. It is envisioned that acquisition of high frequency structural dynamic responses with multiple fiber optic sensors may open new diagnostic capabilities for fiber optic sensing technologies.

Structural dynamic characterization is important for ensuring reliability and operability of spacecraft payloads in harsh environments. During the launch, a structure experiences dynamic loads, including acoustic excitation. Conventional sensors are used to infer structural dynamic characteristics. Limitations of conventional strain sensors include low frequency band, susceptibility to electro-magnetic interference, and use of multiple wires. To mitigate these deficiencies, an innovative fiber optic strain measurement system is considered to obtain strain distribution at specific locations on a payload. Theoretical models are suggested and compared with results of experimental testing. Limitations of analytical models are discussed and comparisons with numerical models are presented. The research addresses the usability of presented models in determining the dynamic response of a payload and variation due to distribution of components. It is proposed that discussed experimental and theoretical procedures can be used in determining structural performance for a variety of missions.
