Overexposure to the sun is associated with an increased risk of melanoma and nonmelanoma skin cancer, but indications of improvements in sun protection behavior are poor. Attempts to identify ...emerging themes in skin cancer control have largely been driven by groups of experts from a single field. In December 2016, 19 experts from various disciplines convened for Interdisciplinary Perspectives on Skin Cancer, a 2-day meeting hosted by the National Academy of Sciences. The group discussed knowledge gaps, perspectives on sun exposure, implications for skin cancer risk and other health outcomes, and new directions. Five themes emerged from the discussion: (1) The definition of risk must be expanded, and categories for skin physiology must be refined to incorporate population diversities. (2) Risky sun exposure often co-occurs with other health-related behaviors. (3) Messages must be nuanced to target at-risk populations. (4) Persons at risk for tanning disorder must be recognized and treated. (5) Sun safety interventions must be scalable. Efficient use of technologies will be required to sharpen messages to specific populations and to integrate them within multilevel interventions. Further interdisciplinary research should address these emerging themes to build effective and sustainable approaches to large-scale behavior change.
Following a thorough site investigation, a biological
Sequential Reactive Barrier (SEREBAR), designed to remove
Polycyclic Aromatic Hydrocarbons (PAHs) and BTEX
compounds, was installed at a Former ...Manufactured Gas
Plant (FMGP) site. The novel design of the barrier
comprises, in series, an interceptor and six reactive
chambers. The first four chambers (2 nonaerated-2 aerated)
were filled with sand to encourage microbial colonization.
Sorbant Granular Activated Carbon (GAC) was present
in the final two chambers in order to remove any recalcitrant
compounds. The SEREBAR has been in continuous
operation for 2 years at different operational flow rates
(ranging from 320 L/d to 4000 L/d, with corresponding residence
times in each chamber of 19 days and 1.5 days, respectively).
Under low flow rate conditions (320-520 L/d) the majority
of contaminant removal (>93%) occurred biotically within
the interceptor and the aerated chambers. Under high
flow rates (1000-4000 L/d) and following the installation
of a new interceptor to prevent passive aeration, the majority
of contaminant removal (>80%) again occurred biotically
within the aerated chambers. The sorption zone (GAC) proved
to be an effective polishing step, removing any remaining
contaminants to acceptable concentrations before
discharge down-gradient of the SEREBAR (overall removals
>95%).

The effects of three previewing procedures on the oral re-reading performance of secondary students with learning disabilities (N = 14, aged 14-15) across passages written at sixth- & twelfth-grade ...levels were investigated. During listening previewing (LP), Ss followed along with reading at fast (FRLP) or slow rates (SRLP). During silent previewing (SP), Ss read passages independently. Results showed no interactions between passage level & interventions, but did show that FRLP, SRLP, & SP resulted in higher rates of accurate oral re-reading than no previewing control. FRLP also resulted in higher rates of accurate oral re-reading than SP. SRLP resulted in lower error levels than SP. 1 Table, 22 References. Adapted from the source document
