Effect of habituation on the susceptibility of the rat to restraint ulcers
The frequency and gravity of restraint ulcers were found to significantly diminish in rats previously exposed to brief periods of immobilization. The rats' becoming habituated to restraint conditions probably explains this phenomenon
Quantum Resonances of Weakly Linked, Mesoscopic, Superconducting Dots
We examine quantum properties of mesoscopic, Josephson coupled
superconducting dots, in the limit that charging effects and quantization of
energy levels within the dots are negligible, but quasi-particle transmission
into the weak link is not. We demonstrate that quasi-particle resonances lead
to current-phase relations, which deviate markedly from those of weak links
connecting macroscopic superconductors. Results for the steady state dc
Josephson current of two coupled dots are presented.Comment: Tex, 3 figures available on request to [email protected] (Andy

A Reappraisal of the Solar Photospheric C/O Ratio
Accurate determination of photospheric solar abundances requires detailed
modeling of the solar granulation and accounting for departures from local
thermodynamical equilibrium (LTE). We argue that the forbidden C I line at 8727
A is largely immune to departures from LTE, and can be realistically modeled
using LTE radiative transfer in a time-dependent three-dimensional simulation
of solar surface convection. We analyze the [C I] line in the solar flux
spectrum to derive the abundance log epsilon(C)= 8.39 +/- 0.04 dex. Combining
this result with our parallel analysis of the [O I] 6300 A line, we find
C/O=0.50 +/- 0.07, in agreement with the ratios measured in the solar corona
from gamma-ray spectroscopy and solar energetic particles.Comment: 5 pages, 2 figures, to appear in ApJL July 1

Is it what you inherited or what you learnt ? Intergenerational linkage and interpersonal inequality in Senegal
Institutional features of the African setting -- large extended families and imperfect credit and land markets -- matter to the equity and efficiency roles played by intergenerational linkages. Using original survey data on Senegal that include an individualized measure of consumption, this paper studies the role played by land inheritance, other bequests and parental background as influences on an adult's economic welfare and economic activities. Although intergenerational linkages are evident, the analysis finds a seemingly high degree of mobility across generations, associated with the shift from farm to non-farm sectors and the greater economic activity of women. Male-dominated bequests of land and housing bring little gain to mean consumption and play little role in explaining inequality, although they have effects on the sector of activity. Inheritance of non-land assets and the education and occupation of parents (especially the mother) and their choices about children's schooling are more important to adult welfare than property inheritance. Significant gender inequality in consumption is evident, although it is almost entirely explicable in terms of factors such as education and (non-land) inheritance. There are a number of other pronounced gender differences, with intergenerational linkages coming through the mother rather than the father.Population Policies,Gender and Law,Agricultural Knowledge&Information Systems,Rural Development Knowledge&Information Systems,Gender and Health
A micro-decomposition analysis of the macroeconomic determinants of human development
This paper shows how differences in aggregate human development outcomes over time and space can be additively decomposed into a pure economic-growth component, a component attributed to differences in the distribution of income, and components attributed to"non-income"factors and differences in the model linking outcomes to income or non-income characteristics. The income effect at the micro level is modeled non-parametrically, so as to flexibly reflect distributional changes. The paper illustrates the decomposition using data for Morocco and Vietnam, and the results offer some surprising insights into the observed aggregate gains in schooling attainments. A user friendly STATA program is available to implement the method in other settings.Primary Education,Education For All,Population Policies,Rural Poverty Reduction,Inequality
