The artesian water of the Ruskin area of Hillsborough County, Florida: interim report

The purpose of the investigation is to make a detailed study of the geology and ground water in the Ruskin area, especially as related to the problem of salt-water encroachment. The major objectives of the program includes: (1) An inventory of wells to determine their number and distribution, their depths and diameters, and other pertinent information. (2) A study of artesian pressures. (3) Analyses of water from selected wells to determine the location and extent of any areas in which the artesian water is salty. (4) A study of the surface and subsurface geology as related to the occurrence and movement of ground water. (5) An estimate of the quantity of ground water withdrawn. (PDF contains 24 pages.

A New Technique for Determining Europium Abundances in Solar-Metallicity Stars

We present a new technique for measuring the abundance of europium, a representative r-process element, in solar-metallicity stars. Our algorithm compares LTE synthetic spectra with high-resolution observational spectra using a chi-square-minimization routine. The analysis is fully automated, and therefore allows consistent measurement of blended lines even across very large stellar samples. We compare our results with literature europium abundance measurements and find them to be consistent; we also find our method generates smaller errors.Comment: 10 pages, 7 figure

Interview with Kathryn Peek

An oral history interview with Kathryn Elaine Hickman Peek about her career as a biomedical administrator and educator at many institutions in the Texas Medical Center. Kathryn Elaine Peek, Ph.D. completed her bachelor’s degree in English and embarked on a first career as a public school teacher. She obtained master’s degrees in biology and behavioral sciences at the University of Houston and UH Clear Lake during two stays in the Houston area. She entered the University of Texas Graduate School of Biomedical Sciences at what is now the McGovern Medical School at the age of 39. She graduated with a Ph.D. in biomedical sciences at the age of 44 and embarked on a career that took her from laboratory studies of brain and spinal cord ischemia to the pursuit of information about the biological differences between men and women. Along the way, she mentored many young people pursuing healthcare and science careers and supported numerous women seeking career advancement in STEM professions. Her career was sometimes at the mercies of institutional politics. She retired from the University of Houston in 2013, but as she continues to work as a consultant in the Texas Medical Center, she can look back on raising awareness of women’s health issues as well as boosting the presence of women in leadership positions in the Texas Medical Center

Exposure Outliers: Children, Mothers, and Cumulative Disaster Exposure in Louisiana

Only a limited number of studies have explored the effects of cumulative disaster exposure—defined here as multiple, acute onset, large-scale collective events that cause disruption for individuals, families, and entire communities. Research that is available indicates that children and adults who experience these potentially traumatic community-level events are at greater risk of a variety of negative health outcomes and ongoing secondary stressors throughout their life course. The present study draws on in-depth interviews with a qualitative subsample of nine mother-child pairs who were identified as both statistical and theoretical outliers in terms of their levels of disaster exposure through their participation in a larger, longitudinal Women and Their Children’s Health (WaTCH) project that was conducted following the British Petroleum Deepwater Horizon Oil Spill. During Wave 2 of the WaTCH study, mothers and their children were asked survey questions about previous exposure to and the impacts of the oil spill, hurricanes, and other disasters. This article presents the qualitative interview data collected from the subsample of children and mothers who both endorsed that they had experienced three or more disasters that had a major impact on the child and the household. We refer to these children as exposure outliers. The in-depth narratives of the four mother-child pairs who told stories of multiple pre-disaster stressors emerging from structural inequalities and health and financial problems, protracted and unstable displacements, and high levels of material and social losses illustrate how problems can pile up to slow or completely hinder individual and family disaster recovery. These four mother-child pairs were especially likely to have experienced devastating losses in Hurricane Katrina in 2005, which then led to an accumulation of disadvantage and ongoing cycles of loss and disruption. The stories of the remaining five mother-child pairs underscore how pre-disaster resources, post-disaster support, and institutional stabilizing forces can accelerate recovery even after multiple disaster exposures. This study offers insights about how families can begin to prepare for a future that is likely to be increasingly punctuated by more frequent and intense extreme weather events and other types of disaster

An Empirical Analysis of the Role of Risk Aversion in Executive Compensation Contracts

This paper empirically tests the principal-agent model prediction that the use of performance measures for incentive purposes is affected by the agent’s risk aversion. We find that the use of both accounting and market performance measures in executive compensation contracts decreases as the level of risk aversions increases. We further find that agent-specific characteristics, i.e., risk aversion, become more important in designing executive compensation contracts when performance measures are less useful due to measure-specific characteristics.Economics ;

The capital crunch: neither a borrower nor a lender be

The dramatic reduction in the growth rate of bank lending associated with the 1990-91 recession, particularly in New England, has evoked claims by many observers of a credit crunch. However, because of the difficulty in determining whether the observed slow credit growth is a demand or supply phenomenon, convincing evidence of the practical importance of credit crunches for economic activity remains elusive. We overcome this obstacle by examining a cross-section of banks in New England that have experienced the same economic downturn, effectively controlling for changes in demand. We find empirical support for a capital crunch, whereby poorly capitalized institutions shrink to satisfy capital requirements. This alone is not a sufficient condition for a credit crunch. However, we find s6me additional evidence that the capital crunch may have limited credit availability in New England.Bank capital ; New England
