The Contribution of Educational Changes to Fertility Declines in Low‐ and Middle‐Income Countries

Studies in Family Planning, EarlyView.
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 ...

Strategic (Inconsistent) Disclosures and Sophisticated Investors: Evidence from Hedge Funds

Journal of Accounting Research, Volume 64, Issue 2, Page 923-978, May 2026.
ABSTRACT Recent SEC regulations require that qualified hedge fund advisers provide their investors with narrative disclosures of their business and operations. We find that 40% of these disclosures omit or de‐emphasize information regarding advisers' operational and investment risks when compared to other sources of public information. Funds with such “

Robust image watermarking using ant colony optimization and fast generic radial harmonic Fourier moment calculation

IET Image Processing
In open networks, the geometric deformation and common image processing are common image manipulation modes, which pose a great challenge in robust watermarking. To improve the robustness of GRHFM‐based watermarking, a watermarking algorithm based on the

The Benefits of Access: Evidence from Private Meetings with Portfolio Firms

The Journal of Finance, Volume 81, Issue 2, Page 739-789, April 2026.
ABSTRACT We use large language models to analyze the content of 4,700 private meetings between a large active asset manager and its portfolio firms. The high‐level meetings convey mostly soft information about the firm, and little about industry or market. Fund manager meetings focus on business models and financial metrics, while governance specialist

Digital Image Watermarking Using Ellipse Watermark

, 2017
From past few decades watermarking became very crucial for digital images being transmitted over network. All the time ownership and license are great issues if someone fetches the image sent by one without any ownership seal, i.e. watermark, and uses as his own image.

A Novel Secure and Robust Image Watermarking Method Based on Decorrelation of Channels, Singular Vectors, and Values

Advances in Electrical and Computer Engineering, 2017
A novel secure and robust image watermarking technique for color images is presented in this paper. Besides robustness and imperceptibility (which are the most important requisites of any watermarking scheme), there are two other challenges a good ...
