Social inequality, poverty and social redistribution
In this essay, I review developments in the ongoing debate about the causal connections between poverty, personal behaviour and social inequality. I also discuss the normative issues that arise in defining poverty and in deciding what role redistributive social policies ought to play in its prevention and relief.I go on to compare the behavioural explanations of the causes of poverty that are normatively associated with theories of economic market liberalism and the structural explanations that are grounded in theories of socialism and other more pluralist forms of social-democratic collectivism.I conclude that these two unitary ideologies of individualism and collectivism are reaching the end of their useful lives as exclusive guides in shaping the ends and means of social policies. In democratic societies, compromises have to be made between radically different views about what constitutes an equitable distribution of wealth and income, and what kind of balance should be struck between the claims of freedom and welfare. Viable compromises on these divisive issues can only be reached in the mixed economies of democratic pluralist societies
Remote Sensing of Spectral Aerosol Properties: A Classroom Experience
Bridging the gap between current research and the classroom is a major challenge to today s instructor, especially in the sciences where progress happens quickly. NASA Goddard Space Flight Center and the University of Maryland teamed up in designing a graduate class project intended to provide a hands-on introduction to the physical basis for the retrieval of aerosol properties from state-of-the-art MODIS observations. Students learned to recognize spectral signatures of atmospheric aerosols and to perform spectral inversions. They became acquainted with the operational MODIS aerosol retrieval algorithm over oceans, and methods for its evaluation, including comparisons with groundbased AERONET sun-photometer data
Evaluating surface radiation fluxes observed from satellites in the southeastern Pacific Ocean

The definitive version was published in Geophysical Research Letters 45 (2018): 2404-2412, doi:10.1002/2017GL076805.This study is focused on evaluation of current satellite and reanalysis estimates of surface radiative fluxes in a climatically important region. It uses unique observations from the STRATUS Ocean Reference Station buoy in a region of persistent marine stratus clouds 1,500 km off northern Chile during 2000–2012. The study shows that current satellite estimates are in better agreement with buoy observations than model outputs at a daily time scale and that satellite data depict well the observed annual cycle in both shortwave and longwave surface radiative fluxes. Also, buoy and satellite estimates do not show any significant trend over the period of overlap or any interannual variability. This verifies the stability and reliability of the satellite data and should make them useful to examine El Niño–Southern Oscillation variability influences on surface radiative fluxes at the STRATUS site for longer periods for which satellite record is available.National Oceanic and Atmospheric Administration Grant Number: NA14OAR4320158;

The linked survival prospects of siblings : evidence for the Indian states
This paper reports an analysis of micro-data for India that shows a high correlation in infant mortality
among siblings. In 13 of 15 states, we identify a causal effect of infant death on the risk of infant death of the
subsequent sibling (a scarring effect), after controlling for mother-level heterogeneity. The scarring effects
are large, the only other covariate with a similarly large effect being mother’s (secondary or higher)
education. The two states in which evidence of scarring is weak are Punjab, the richest, and Kerala, the
socially most progressive. The size of the scarring effect depends upon the sex of the previous child in three
states, in a direction consistent with son-preference. Evidence of scarring implies that policies targeted at
reducing infant mortality will have social multiplier effects by helping avoid the death of subsequent
siblings. Comparison of other covariate effects across the states offers some interesting new insights
The future of human nature: a symposium on the promises and challenges of the revolutions in genomics and computer science, April 10, 11, and 12, 2003
This repository item contains a single issue of the Pardee Conference Series, a publication series that began publishing in 2006 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future. This was the Center's Symposium on the Promises and Challenges of the Revolutions in Genomics and Computer Science took place during April 10, 11, and 12, 2003. Co-organized by Charles DeLisi and Kenneth Lewes; sponsored by Boston University, the Frederick S. Pardee Center for the Study of the Longer-Range Future.This conference focused on scientific and technological advances in genetics, computer science, and their convergence during the next 35 to 250 years. In particular, it focused on directed evolution, the futures it allows, the shape of society in those futures, and the robustness of human nature against technological change at the level of individuals, groups, and societies. It is taken as a premise that biotechnology and computer science will mature and will reinforce one another. During the period of interest, human cloning, germ-line genetic engineering, and an array of reproductive technologies will become feasible and safe. Early in this period, we can reasonably expect the processing power of a laptop computer to exceed the collective processing power of every human brain on the planet; later in the period human/machine interfaces will begin to emerge. Whether such technologies will take hold is not known. But if they do, human evolution is likely to proceed at a greatly accelerated rate; human nature as we know it may change markedly, if it does not disappear altogether, and new intelligent species may well be created

Tabula Rasa and Human Nature
It is widely believed that the philosophical concept of 'tabula rasa' originates with Locke's Essay Concerning Human Understanding and refers to a state in which a child is as formless as a blank slate. Given that both these beliefs are entirely false, this article will examine why they have endured from the eighteenth century to the present. Attending to the history of philosophy, psychology, psychiatry and feminist scholarship it will be shown how the image of the tabula rasa has been used to signify an originary state of formlessness, against which discourses on the true nature of the human being can differentiate their position. The tabula rasa has operated less as a substantive position than as a whipping post. However, it will be noted that innovations in psychological theory over the past decade have begun to undermine such narratives by rendering unintelligible the idea of an 'originary' state of human nature
Could the 2012 Drought in Central U.S. Have Been Anticipated? A Review of NASA Working Group Research
This paper summarizes research related to the 2012 record drought in the central United States conducted by members of the NASA Energy and Water cycle Study (NEWS) Working Group. Past drought patterns were analyzed for signal coherency with latest drought and the contribution of long-term trends in the Great Plains low-level jet, an important regional circulation feature of the spring rainy season in the Great Palins. Long-term changes in the seasonal transition from rainy spring into dry summer were also examined. Potential external forcing from radiative processes, soil-air interactions, and ocean teleconnections were assessed as contributors to the intensity of the drought. The atmospheric Rossby wave activity was found to be a potential source of predictability for the onset of drought. A probabilistic model was introduced and evaluated for its performance in predicting drought recovery in the Great Plains
