The Motherhood Wage Penalty: Sorting Versus Differential Pay
The motherhood wage penalty is today probably the largest obstacle to progress in gender equality at work. Using matched employer-employee data from Norway (1980–97), a country with public policies that promote combining family and career, we investigate (a) whether the penalty arises from differential pay by employers or from sorting of employees on occupations and establishments, and (b) chan...
متن کاملPhysostomous channel catfish, Ictalurus punctatus, modify swimming mode and buoyancy based on flow conditions.
The employment of gliding in aquatic animals as a means of conserving energy has been theoretically predicted and discussed for decades. Several studies have shown that some species glide, whereas others do not. Freshwater fish species that widely inhabit both lentic and lotic environments are thought to be able to adapt to fluctuating flow conditions in terms of locomotion. In adapting to the ...
متن کاملCasimir Buoyancy
We study the Casimir force on a single surface immersed in an inhomoge-neous medium. Specifically we study the vacuum fluctuations of a scalar field with a spatially varying squared mass, m 2 + λ∆(x − a) + V (x), where V is a smooth potential and ∆(x) is a unit-area function sharply peaked around x = 0. ∆(x − a) represents a semi-penetrable thin plate placed at x = a. In the limits {∆(x−a) → δ(...
متن کاملBuoyancy and Strength
The chief characteristic of presuppositions is that they tend to take wide scope, yet most theories of presupposition, the author's not excepted, fail to provide an explanation of this fact. Recently, however, it has been suggested that a principled explanation can be given in terms of informativeness: the idea is that presuppositions simply prefer stronger readings to weaker ones. This proposa...
متن کاملThe Presence of Buoyancy
Laminar natural convection flow and heat transfer of a viscous incompressible fluid confined between two long vertical wavy walls has been analysed taking the fluid properties constant and variable. In particular, attention is restricted to estimate the effects of viscous dissipation and wall waviness on the flow and heat transfer characteristics. Use has been made of a llnearlzatlon technique ...
