Test power properties of within-firm estimators of ownership and board-related explanatory variables with low time variation
(SpringerUS, 2022-07-16)
Corporate governance research is often limited in its ability to employ within-firm estimators, which address time-invariant endogeneity, when the variables of interest exhibit low time variation (for example, ownership ...

Variation in body size and metamorphic traits of Iberian spadefoot toads over a short geographic distance
(Wiley Blackwell Publishing, Inc, 2008-06)
Determinants of geographic variation in body size are often poorly understood, especially in organisms with complex life cycles. We examined patterns of adult body size and metamorphic traits variation in Iberian spadefoot ...
Daily Variation in Plasma Zinc Concentrations in Women Fed Meals at Six-Hour Intervals
(1994)
Ten pre-menopausal women participated in two studies to measure the daily variations in plasma zinc when meals were fed at 6-h intervals and to determine if the response was related to shifts in serum insulin, glucose, ...
Genetic variation in the reduction of attractive floral traits of an annual tarweed in response to drought and apical damage
(Oxford University Press, 2015)
Foliar herbivory and water stress may affect floral traits attractive to pollinators. Plant genotypes may differ in their responses to the interplay between these factors, and evolution of phenotypic plasticity could be ...
Ionospheric and thermospheric variations associated with prompt penetration electric fields
(American Geophysical Union, 2012-08-10)
This paper presents a comprehensive modeling investigation of ionospheric and thermospheric variations during a prompt penetration electric field (PPEF) event that took place on 9 November 2004, using the Thermosphere‐Io ...
Response of the topside and bottomside ionosphere at low and middle latitudes to the October 2003 superstorms
(American Geophysical Union, 2015-07-14)
Ionospheric observations from the ground‐based GPS receiver network, CHAMP and GRACE satellites and ionosondes were used to examine topside and bottomside ionospheric variations at low and middle latitudes over the Pacific ...
Soluble carbohydrates content in tomato pollen and its variations along and between blooming periods
(Elsevier Science, 2010-05)
The soluble carbohydrates content in the mature (starchless) pollen of the tomato (Solanum lycopersicum L.) cv. Platense was studied at several moments of the blooming period in two consecutive years. The aim of the analysis ...
Optimal low-cost transfer to L4 and L5 lagrangian points based on G-family of periodic orbits
(2012-12-01)
An alternative transfer strategy to send spacecrafts to stable orbits around the Lagrangian equilibrium points L4 and L5 based in trajectories derived from the periodic orbits around LI is presented in this work. The ...
