A New Frontier: The Development and Validation of the Intimate Partner Cyber Abuse Instrument

As technology advances, new opportunities for partners to gain power and control in their romantic relationships are readily available. New cyber-based behaviors have slowly garnered scholarly attention, but measurement-related issues have not. We take the logical next steps to (1) develop and validate a comprehensive measure of intimate partner cyber abuse (IPCA) for adults using classical test theory and item response theory and (2) estimate IPCA prevalence rate for a range of relationship types. A sample of 1,500 adults, currently in an intimate partner relationship, 18 years or older, and living in the United States, completed an online questionnaire about their IPCA experiences within the 6 months prior. Two parameter logistic modeling and confirmatory factor analyses revealed a five-dimensional structure: cyber direct aggression, cyber sexual coercion, cyber financial control, cyber control, and cyber monitoring, with 14.85% of the sample experiencing at least one dimension. These IPCA dimensions were examined for differential functioning across gender identity, race, student status, and relationship type. Collectively, the findings have implications for IPCA measurement and related research, including theoretically derived hypotheses whose findings can inform prevention

#MeToo for Whom? Sexual Assault Disclosures Before and After #MeToo

In October 2017, #MeToo became a global hashtag for victims of sexual assault and harassment. In this study, we examine the extent of unwanted sexual experiences and disclosure, as well as perceptions of #MeToo, to assess differences among students who were represented and underrepresented in #MeToo coverage. Using a stratified random sample of students at a private university in the mid-Atlantic region of the U.S., we analyzed data from cross-sectional surveys conducted in March 2017 (n = 1722) and March 2019 (n = 1503). Results suggest that, relative to White students, in 2019 compared to 2017, there was an increase in disclosures among Black students and a decrease among Multiracial students. There was also an increase in undergraduate students who indicated ever experiencing unwanted sexual activity in 2019. Students who believed #MeToo affected how they think about past experiences were more likely to have indicated past experiences with unwanted sexual activity. Results also suggest that cisgender women, LGBQ, white, and multiracial students are at increased risk of unwanted sexual activity. However, Asian students, cisgender men, and non-LGBQ students may be less likely to disclose unwanted sexual activity. Implications for evaluating long-term impacts of #MeToo are discussed, along with suggestions for future research

Dust polarized emission observations of NGC 6334: BISTRO reveals the details of the complex but organized magnetic field structure of the high-mass star-forming hub-filament network

Context. Molecular filaments and hubs have received special attention recently thanks to new studies showing their key role in star formation. While the (column) density and velocity structures of both filaments and hubs have been carefully studied, their magnetic field (B-field) properties have yet to be characterized. Consequently, the role of B-fields in the formation and evolution of hub-filament systems is not well constrained. Aims. We aim to understand the role of the B-field and its interplay with turbulence and gravity in the dynamical evolution of the NGC 6334 filament network that harbours cluster-forming hubs and high-mass star formation. Methods. We present new observations of the dust polarized emission at 850 μm toward the 2 pc 7 10 pc map of NGC 6334 at a spatial resolution of 0.09 pc obtained with the James Clerk Maxwell Telescope (JCMT) as part of the B-field In STar-forming Region Observations (BISTRO) survey. We study the distribution and dispersion of the polarized intensity (PI), the polarization fraction (PF), and the plane-of-The-sky B-field angle (χB_POS) toward the whole region, along the 10 pc-long ridge and along the sub-filaments connected to the ridge and the hubs. We derived the power spectra of the intensity and χBPOS along the ridge crest and compared them with the results obtained from simulated filaments. Results. The observations span 3 orders of magnitude in Stokes I and PI and 2 orders of magnitude in PF (from 0.2 to 20%). A large scatter in PI and PF is observed for a given value of I. Our analyses show a complex B-field structure when observed over the whole region ( 10 pc); however, at smaller scales (1 pc), χBPOS varies coherently along the crests of the filament network. The observed power spectrum of χBPOS can be well represented with a power law function with a slope of-1.33 \ub1 0.23, which is 20% shallower than that of I. We find that this result is compatible with the properties of simulated filaments and may indicate the physical processes at play in the formation and evolution of star-forming filaments. Along the sub-filaments, χBPOS rotates frombeing mostly perpendicular or randomly oriented with respect to the crests to mostly parallel as the sub-filaments merge with the ridge and hubs. This variation of the B-field structure along the sub-filaments may be tracing local velocity flows of infalling matter in the ridge and hubs. Our analysis also suggests a variation in the energy balance along the crests of these sub-filaments, from magnetically critical or supercritical at their far ends to magnetically subcritical near the ridge and hubs. We also detect an increase in PF toward the high-column density (NH2 \ue2 1023 cm-2) star cluster-forming hubs. These latter large PF values may be explained by the increase in grain alignment efficiency due to stellar radiation from the newborn stars, combined with an ordered B-field structure. Conclusions. These observational results reveal for the first time the characteristics of the small-scale (down to 0.1 pc) B-field structure of a 10 pc-long hub-filament system. Our analyses show variations in the polarization properties along the sub-filaments that may be tracing the evolution of their physical properties during their interaction with the ridge and hubs. We also detect an impact of feedback from young high-mass stars on the local B-field structure and the polarization properties, which could put constraints on possible models for dust grain alignment and provide important hints as to the interplay between the star formation activity and interstellar B-fields
