Can teaching be taught? Improving teachers' pedagogical skills at scale in rural Peru
Quantitative Economics, Volume 16, Issue 1, Page 185-233, January 2025.We evaluate the impact of a large‐scale teacher coaching program in Peru, a context with high teacher turnover, on teachers' pedagogical skills and student learning. Previous studies find that small‐scale coaching programs can improve teaching of reading and science in developing countries.

Review of Education, Volume 12, Issue 3, December 2024.Abstract The world map is changing due to waves of immigration, population and demographic changes in mainland Europe and North America. There is a growing need for a more diverse teacher workforce to close the racial and ethnic gap between students and teachers in populations with high diversity.

Variability of Blazars and Blazar Models over 38 Years [PDF]
Galaxies, 2016 Since 1978, when BL Lac objects and violently variable quasars were married to become “blazars”, physical interpretations of the phenomenon have evolved. Remarkably, though, the general picture of relativistic jets beaming their radiation in our direction, proposed that year by Blandford and Rees, remains intact.

Lessons from the apparent peculiar nature of the star TYC 6544‐3483‐1
Astronomische Nachrichten, Volume 345, Issue 4, May 2024.Abstract We report a radio and optical study of the star TYC 6544‐3483‐1 originally selected as a follow‐up target in the course of our efforts to cross‐identify Galactic high‐energy sources. The star by itself finally turned out to be a very ordinary main‐sequence star despite the initial expectations that apparently pointed to the contrary.

H.E.S.S. Monitoring of PKS 2155-304 in 2015 and 2016
Galaxies, 2019 PKS 2155-304 is one of the brightest blazar located in Southern Hemisphere, monitored with H.E.S.S. since the first light of the experiment. Here we report multiwavelength monitoring observations collected during the period of 2015–2016 with H.E.S.S ...

Publications of the Astronomical Society of Japan, 2002 Based on the beaming model, a relation between the observed polarization and the Doppler factor was obtained by Fan et al. (1997, AAA068.159.190), who showed that the polarization is associated with the Doppler factor (boosting factor) in BL Lacertae objects (BLs).

The Astrophysical JournalThe blazar TXS 0506+056 has been proposed as a high-energy neutrino emitter. However, it has been shown that the standard one-zone model cannot produce sufficiently high neutrino flux due to constraints from the X-ray data, implying more complex ...

Boosted dark matter versus dark matter-induced neutrinos from single and stacked blazars
Journal of High Energy PhysicsThe physics responsible for the production of observed high-energy neutrinos have not been established so far, neither for the diffuse astrophysical ones nor for those detected from single blazars.
