Assessing parental understanding of sexualized behavior in children and adolescents

The current study assessed parents’ ability to identify normal, concerning and harmful sexualized behaviors in children and adolescents, as well as the parents’ ability to identify and select an appropriate level of intervention. The influence of a parent’s relationship with the victim or the perpetrator on the level of action taken was also examined. A cross-sectional survey incorporating a randomized experimental vignette condition determined that parents (N = 244) were not able to consistently identify sexualized behaviors accurately, and they provided lower-than-recommended levels of intervention responses. Parents were best able to identify and respond to behaviors considered normal and age-appropriate, but had greater difficulty with behaviors considered concerning or harmful. Parents were significantly less able to accurately identify and respond to behaviors exhibited by very young children (in the 0–4 year-old age-bracket). In three vignette comparisons, no significant difference in the level of intervention responses was found between parents who viewed the victim as their own child and parents who viewed the perpetrator as their child; while parents who viewed both the victim and perpetrator as being their children (siblings) reported lower intervention response levels. Because a lack of accurate knowledge around risks and indicators of child sexual abuse negatively affects the ability to prevent and detect abuse, the results have implications for a shift from a forensic model of child protection towards a public health model, which emphasizes parent and community education

Four-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: On-sky Receiver Performance at 40, 90, 150, and 220 GHz Frequency Bands

The Cosmology Large Angular Scale Surveyor (CLASS) observes the polarized cosmic microwave background (CMB) over the angular scales of 1$^\circ \lesssim \theta \leq$ 90$^\circ$ with the aim of characterizing primordial gravitational waves and cosmic reionization. We report on the on-sky performance of the CLASS Q-band (40 GHz), W-band (90 GHz), and dichroic G-band (150/220 GHz) receivers that have been operational at the CLASS site in the Atacama desert since June 2016, May 2018, and September 2019, respectively. We show that the noise-equivalent power measured by the detectors matches the expected noise model based on on-sky optical loading and lab-measured detector parameters. Using Moon, Venus, and Jupiter observations, we obtain power-to-antenna-temperature calibrations and optical efficiencies for the telescopes. From the CMB survey data, we compute instantaneous array noise-equivalent-temperature sensitivities of 22, 19, 23, and 71 $\mathrm{\mu K}_\mathrm{cmb}\sqrt{\mathrm{s}}$ for the 40, 90, 150, and 220 GHz frequency bands, respectively. These noise temperatures refer to white noise amplitudes, which contribute to sky maps at all angular scales. Future papers will assess additional noise sources impacting larger angular scales.Comment: 13 pages, 3 figures, published in Ap
