Restoring Trust: A Grounded Theory Study of Cyberbullying Among Young Women

Cyberbullying is a global and national public health issue with the potential to affect the healthy social and emotional development of adolescents and young adults. There has been an 80% increase in social media use in 18-29 year olds between 2004 and 2014 (Gahagen, Vaterlaus, & Frost, 2016). In a study of 14-24 year olds (MTV/AP, 2011), 76% identified cyberbullying as a serious problem, with more than 56% reporting they have experienced cyberbullying. Cyberbullying research has been conducted predominantly with adolescents (ages 11-18 years), however scant research has been conducted with older adolescents and young adults (ages 18-30 years). This classical grounded theory study explored the process of cyberbullying victimization from the perspective of 15 young women ages 18-30 years old. Data were collected through semi-structured interviews and analyzed using constant comparison. The substantive theory that emerged from the data is comprised of the core category, Restoring Trust, and five key categories: Becoming the Target, Suffering in Silence, Reaching Out, Receiving Support, and Becoming Empowered. Of significance is the discovery of trust as the dynamic that moves the process forward. Trust is initially lost when the young woman becomes the target, and then restored through the process of reaching out for help, receiving support, and becoming empowered. Being believed is the gateway to restoring trust. Knowledge and insights gained from this study will inform prevention and intervention strategies

Raman Signal Extraction from CARS Spectra Using a Learned-Matrix Representation of the Discrete Hilbert Transform

Removing distortions in coherent anti-Stokes Raman scattering (CARS) spectra due to interference with the nonresonant background (NRB) is vital for quantitative analysis. Popular computational approaches may generate significant errors for peaks that extend in any part beyond the recording window. In this work, we present a learned matrix approach to the discrete Hilbert transform that is easy to implement, fast, and dramatically improves accuracy of Raman retrieval for Kramers-Kronig approaches.Comment: 22 pages (15 main, 7 supplement), 7 figures (4 main, 3 supplement

Summary Proceedings of a Wind Shear Workshop

A number of recent program results and current issues were addressed: the data collection phase of the highly successful Joint Airport Weather Study (JAWS) Project and the NASA-B5f7B Gust Gradient Program, the use of these data for flight crew training through educational programs (e.g., films) and with manned flight training simulators, methods for post-accident determination of wind conditions from flight data recorders, the microburst wind shear phenomenon which was positively measured and described the ring vortex as a possible generating mechanism, the optimum flight procedure for use during an unexpected wind shear encounter, evaluation of the low-level wind shear alert system (LLWSAS), and assessment of the demonstrated and viable application of Doppler radar as an operational wind shear warning and detection system
