We revisit the question of whether the Rodgers Creek fault in northern California is creeping, a question with implications for seismic hazard. Using imagery acquired by Envisat between 2003 and 2010, we process two persistent scatterer interferometric synthetic aperture radar (InSAR) data sets, one from an ascending track and the other from a descending track, covering the northernmost segment of the Rodgers Creek fault between the cities of Santa Rosa and Healdsburg. The two different viewing geometries provided by the two different tracks allow us to distinguish vertical velocities, which may reflect nontectonic deformation processes, from fault‐parallel velocities, which can be used to identify creep. By measuring offsets in InSAR line‐of‐sight velocity from 12 fault‐perpendicular profiles through both data sets, we identify seven locations where we have a high degree of confidence that creep is occurring (estimated creep rate is more than two standard deviations above zero). The preferred creep rates at these locations are in the range 1.9–6.7 mm/yr, consistent within uncertainty with alignment array measurements. Creep is probable (P≥0.70) at another three locations, defining a creeping zone ∼20 km long in total, extending northwest from Santa Rosa. We also estimate the map patterns of fault‐parallel and vertical velocities in the region covered by both data sets; these suggest that the Rodgers Creek fault immediately southeast of Santa Rosa remains locked.

This study aimed to explore whether sandplay therapy could offer an effective psychological intervention for middle school students with post-traumatic stress disorder (PTSD). We conducted sandplay therapy on six occasions with second-grade middle school students with PTSD and subsequently observed a significant decrease in their PTSD total scores. Our follow-up assessments of the subjects six months later showed that the related indicators remained within an acceptable range. Based on these results, we have concluded that sandplay therapy offers an effective psychological intervention for teenagers with PTSD.

Abstract-S ince the 21st century, all countries in the world have continuously increased investment in education, increased spending on education, and adjusted the optimal allocation of educational resources in order to enhance their international competitiveness. This paper selects and analyzes annual spending per student on educational institutions for all services and annual expenditure per student on educational institutions for different types of services which are both in the four levels of primary education, secondary education, post-secondary non-tertiary education and tertiary education from 19 countries in the OECD in 2014. The results showed that: most countries put their funds into tertiary education, while neglecting post-secondary non-tertiary education; the funding investment for primary education and secondary education are huge. How to make a reasonable and optimal allocation of education expenditure is an important issue which is worth of attention.
