CHANGES IN THE WELL-BEING OF NONMETROPOLITAN SINGLE-MOTHER FAMILIES: A SEMI-PARAMETRIC ANALYSIS

In nonmetropolitan areas of the United States, single-mother families contain a majority of children living below the poverty line. Changes between 1992 and 2000 in the economic well-being of nonmetropolitan single-mother families are examined using kernel density estimation and density reweighting methods. The results show that increased education levels of single mothers and the strengthening of area economic conditions explain much of the observed gains in the economic well-being of this family group. But temporal changes in propensities to work and to be on welfare from 1992 to 2000 have also contributed to observed gains.Institutional and Behavioral Economics,

Teachers matter: feelings of school connectedness and positive youth development among Coos County youth

Students who feel positively about their education, have a sense of belonging in school, and maintain good relationships with students and staff generally feel connected to their schools. In fact, 63 percent of Coos youth report feeling this way. It is one of the most important factors in promoting socio-emotional well-being and positive youth development, according to authors Nena Stracuzzi and Meghan Mills. Their research, using surveys of Coos students, shows that students who feel more connected to their schools usually get better grades, have higher self-esteem, use fewer substances, and engage in aggressive behaviors less frequently. Their latest brief also shows that Coos County students who feel their teachers are supportive of them are often more connected to their schools

The June 2012 transit of Venus. Framework for interpretation of observations

Ground based observers have on 5/6th June 2012 the last opportunity of the century to watch the passage of Venus across the solar disk from Earth. Venus transits have traditionally provided unique insight into the Venus atmosphere through the refraction halo that appears at the planet outer terminator near ingress/egress. Much more recently, Venus transits have attracted renewed interest because the technique of transits is being successfully applied to the characterization of extrasolar planet atmospheres. The current work investigates theoretically the interaction of sunlight and the Venus atmosphere through the full range of transit phases, as observed from Earth and from a remote distance. Our model predictions quantify the relevant atmospheric phenomena, thereby assisting the observers of the event in the interpretation of measurements and the extrapolation to the exoplanet case. Our approach relies on the numerical integration of the radiative transfer equation, and includes refraction, multiple scattering, atmospheric extinction and solar limb darkening, as well as an up to date description of the Venus atmosphere. We produce synthetic images of the planet terminator during ingress/egress that demonstrate the evolving shape, brightness and chromaticity of the halo. Guidelines are offered for the investigation of the planet upper haze from vertically-unresolved photometric measurements. In this respect, the comparison with measurements from the 2004 transit appears encouraging. We also show integrated lightcurves of the Venus/Sun system at various phases during transit and calculate the respective Venus-Sun integrated transmission spectra. The comparison of the model predictions to those for a Venus-like planet free of haze and clouds (and therefore a closer terrestrial analogue) complements the discussion and sets the conclusions into a broader perspective.Comment: 14 pages; 14 figures; Submitted on 02/06/2012; A&A, accepted for publication on 30/08/201

NON-METROPOLITAN TO METROPOLITAN COUNTY COMMUTING: GATEWAY TO PROSPERITY OR BARBARIANS AT THE GATE

Fiscal policy in a depressed economy : was there a ‘free lunch’ in 1930s’ Britain?

We report estimates of the fiscal multiplier for interwar Britain based on quarterly data and timeseries econometrics. We find that the government-expenditure multiplier was in the range 0.3 to 0.9 even during the period that interest rates were at the lower bound. The scope for a ‘Keynesian solution’to recession was much less than is generally supposed. In the later 1930s but not before Britain’s exit from the gold standard, there was a ‘fiscal free lunch’in that deficit-financed government spending would have improved public finances enough to pay for the interest on the extra debt

Rearmament to the rescue? New estimates of the impact of ‘Keynesian’ policies in 1930s’ Britain

We report estimates of the fiscal multiplier for interwar Britain based on quarterly data, time-series econometrics, and ‘defense news’. We find that the government expenditure multiplier was in the range 0.3 to 0.8, much lower than previous estimates. The scope for a Keynesian solution to recession was less than is generally supposed. We find that rearmament gave a smaller boost to real GDP than previously claimed. Rearmament may, however, have had a larger impact than a temporary public works program of similar magnitude if private investment anticipated the need to add capacity to cope with future defense spending

On Intra-Annual Poverty in the U.S.: Prevalence, Causes and Response to Food Stamp Program Use

Poverty measurement with data whose reference period is one year masks family exposure to poverty that only lasts for part of the year. We use quarterly expenditure data and decomposable severity of poverty indexes to quantify consumption-based intra-annual poverty, determine its causes and its response to federal food assistance. Results show that twice as many households are poor for at least one quarter then would be classified as poor with annual consumption data. Severity indexes indicate that intra-annual poverty accounts for over one third of the total annual severity of poverty. The common determinants of intra-annual and annual poverty include low human capital, unemployment and minority status. Changes in family size during the year affect intra-annual but not annual poverty. We also find evidence that food stamp program use reduces intra-annual poverty.Food Consumption/Nutrition/Food Safety, Food Security and Poverty,

NON-METROPOLITAN TO METROPOLITAN AREA MIGRATION OF YOUNG ADULTS

The decisions of young adults from non-metropolitan areas to either migrate to metropolitan areas or remain in non-metropolitan areas following the completion of schooling are studied in this paper. The migration decision is decomposed into an hourly initial earnings component and a cost component comprising the financial, psychic, and employment attainment costs of migration. There are three noteworthy findings. First, while the propensity to migrate increases in educational attainment, contrary to conventional wisdom, this is entirely attributable to lower costs to migration among more educated individuals. Second, weak local economic conditions exert a strong influence on migration behavior. Specifically, high local unemployment rates and low per-capita county income significantly increase the cost of migration. Third, expected differences in initial earnings continue to provide an important incentive for young adults to migrate from non-metropolitan to metropolitan areas.Institutional and Behavioral Economics, Labor and Human Capital,

Kinetics of liquid phase semiconductor photoassisted reactions : supporting observations for a pseudo-steady-state model

The kinetics of liquid phase semiconductor photocatalytic and photoassisted reactions are an area of some debate, reignited recently by an article by Ollis1 in which he proposed a simple pseudo-steady-state model to interpret the Langmuir-Hinshelwood type kinetics, commonly observed in such systems. In the current article, support for this model, over other models, is provided by a reinterpretation of the results of a study, reported initially in 1999,2 of the photoassisted mineralization of 4-chlorophenol, 4-CP, by titania films and dispersions as a function of incident light intensity, I. On the basis of this model, these results indicate that 4-CP is adsorbed more strongly on P25 TiO2 when it is in a dispersed, rather than a film form, due to a higher rate constant for adsorption, k1. In addition, the kinetics of 4-CP removal appear to depend on Iâ, where â ) 1 or 0.6 for when the TiO2 is in a film or a dispersed form, respectively. These findings are discussed both in terms of the pseudo-steady-state model and other popular kinetic models
