Agronomic Performance and Water Use Indicators of Cactus Species Widely Cultivated in Semiarid Regions

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT This study aimed to evaluate the agronomic performance, crop evapotranspiration (ETc), crop coefficients (Kc, Kcb and Ke) and yield response factor (Ky) of three forage cactus clones—Orelha de Elefante Mexicana (OEM), Miúda (MIU) and IPA Sertânia (IPA)—grown in a semiarid environment.

Genetic and Environmental Associations Among Pain, Sleep Disturbances, and Substance Use Intent in Early Adolescence

open access: yesJournal of Adolescence, EarlyView.
ABSTRACT Purpose Pain, sleep disturbances, and substance use are common in adolescence, with research indicating that genetic and environmental factors account for variation in each of these behavioral and health outcomes. Moreover, pain, sleep disturbances, and substance use often co‐occur during adolescence. However, research has not examined whether

Financial Shocks, Uncertainty Shocks, and Corporate Liquidity

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT I estimate a structural VAR identified using sign restrictions to separately identify financial, macro uncertainty, and financial uncertainty shocks. The novelty of the estimation procedure relies on the qualitatively different response of corporate liquidity: Financial shocks lead firms to draw down their liquidity as they lose access to ...

Slow Expectation–Maximization Convergence in Low‐Noise Dynamic Factor Models

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT This paper addresses the slow convergence of the expectation–maximization (EM) algorithm in the estimation of low‐noise dynamic factor models, commonly used in macroeconomic nowcasting and forecasting. We show analytically and in Monte Carlo simulations how the EM algorithm stagnates in a low‐noise environment, leading to inaccurate estimates ...
