The Contribution of Educational Changes to Fertility Declines in Low‐ and Middle‐Income Countries
Studies in Family Planning, Volume 57, Issue 2, Page 256-277, June 2026.Abstract Educational expansion is widely regarded as a central mechanism in fertility transitions, yet some research suggests its role may be more modest. This study analyzes birth histories from 414 surveys in 72 low‐ and middle‐income countries to reassess the contribution of the shift in the educational composition of the population to fertility ...

Reversible Watermarking Method for JPEG Images
IEICE Transactions on Information and Systems, 2008 In this letter, we propose a simple reversible watermarking method for JPEG images using the characteristics of JPEG compression. The method embeds a watermark into a JPEG image, and it extracts the watermark from the watermarked JPEG image and at the same time can recover the watermarked JPEG image to an original unwatermarked JPEG image.
