Portraits of the Assets and Liabilities of Low-Income Families

Reviews the assets, debts, and net worth of low-income families compared with middle-income families, as well as those of other at-risk families such as single-parent and minority families. Examines the link between asset holding, net worth, and income

The Role of Expectations and Gender in Altruism

A central question in the study of altruism has been whether there is a systematic gender difference in giving behavior. Most experimental economics research has found that women are more generous than men. Evidence also suggests that gender differences depend upon the price of giving: males are more altruistic when the price of giving is low, while females are more altruistic when the price of giving is high. However, in the modified dictator game, a key variable in one’s decision to give is what one expects to receive. Systematic differences in those expectations may well contribute to systematic differences in altruistic behavior. We show that these expectations drive an important and widely reported result. When these expectations are homegrown, we replicate the finding. When expectations of receiving are uniform rather than homegrown, gender differences in price sensitivity disappear: males and females give equal amounts. This suggests that it is gender differences in expectations about others’ giving — not differences in tastes for fairness — that explains the previous results.altruism, charitable giving, dictator game, gender differences, experiment

Evaluation of WRF-Sfire Performance with Field Observations from the FireFlux experiment

This study uses in-situ measurements collected during the FireFlux field experiment to evaluate and improve the performance of coupled atmosphere-fire model WRF-Sfire. The simulation by WRF-Sfire of the experimental burn shows that WRF-Sfire is capable of providing realistic head fire rate-of-spread and the vertical temperature structure of the fire plume, and, up to 10 m above ground level, fire-induced surface flow and vertical velocities within the plume. The model captured the changes in wind speed and direction before, during, and after fire front passage, along with arrival times of wind speed, temperature, and updraft maximae, at the two instrumented flux towers used in FireFlux. The model overestimated vertical velocities and underestimated horizontal wind speeds measured at tower heights above the 10 m, and it is hypothesized that the limited model resolution over estimated the fire front depth, leading to too high a heat release and, subsequently, too strong an updraft. However, on the whole, WRF-Sfire fire plume behavior is consistent with the interpretation of FireFlux observations. The study suggests optimal experimental pre-planning, design, and execution of future field campaigns that are needed for further coupled atmosphere-fire model development and evaluation

Epaulets in Golden Eagle Plumages in Western Montana

An uncommon plumage characteristic of North American Golden Eagles (Aquila chrysaetos) is the epaulet, a white feather or feathers at the shoulder, often symmetrical on both sides in appearance. The size and shape of an epaulet varies by individual. This characteristic is mentioned within the literature, but is not noted how it is reflected within a population. We have observed epaulets in 17 out of 102 (16.6%) individual Golden Eagles with at least one epaulet in western Montana since 2012. Of these individuals, 13 (76.4%) were observed on the Rocky Mountain Front while on migration, and 4 (23.6%) were observed on wintering grounds in the Bitterroot Valley, Montana. Epaulets have been observed on both male and female individuals, and on both sub-adult and adult aged birds. This plumage characteristic should continue to be recorded in Golden Eagles for a better estimate of rate of occurrence within a population
