Targeting the Treatment: The Strategy behind Lyndon Johnson's Lobbying

Lyndon Johnson woke up studying whip counts, went to bed reading the Congressional Record, and invested countless hours in between translating that political intelligence into a lobbying offensive. The result, famously christened “The Johnson Treatment,” remains the archetype practitioners and political scientists cite when appraising presidential leadership on Capitol Hill. Yet Beltway folklore aside, we know little about how LBJ helped forge winning legislative coalitions. Stepping back from the (countless) colorful anecdotes, this study offers a new and systematic look at Lyndon Johnson's lobbying. Specifically, after exploring theoretical models of presidential coalition building, we then investigate their operational tenets using original data on all President Johnson's contacts, with each member of Congress, in both chambers, for every day he was president.     

Proximal End Root Morphology Characteristics in Antemortem Anagen Head Hairs

The proximal end morphology of antemortem anagen head hair was compared with the characteristics documented to occur in postmortem hairs. Antemortem anagen and telogen head hairs (N = 967) were recovered following exposure to seven environments. Root morphology characteristics consistent with those reported in postmortem hairs were observed in 66 (14%) hairs exposed to a water, normal saline, outdoor soil, or indoor shower environment. Thirty‐three anagen hairs (7%) exhibited a root band at the proximal end. The mean distance from the root tip to the onset of the root band ranged from 0.23 to 0.7 mm, depending on the environment. The mean distance from the root tip to the onset of the root band was 0.46 mm, with a mean band length of 0.44 mm. The results illustrate the need to better characterize postmortem banding through quantitative measurements, including the range for root tip to band distance and the overall band length.     

Lighting and Homicides: Evaluating the Effect of an Electrification Policy in Rural Brazil on Violent Crime Reduction

Introduction

This study estimates the effects of lighting on homicides in rural areas of developing countries.

Methods

We use an IV strategy by exploring the LUZ PARA TODOS or Light for All (LPT) program that was adopted by the federal government to expand electrification to rural areas in Brazilian municipalities in the 2000s as an exogenous source of variations in access to electricity.

Results

Our results indicate a significant decrease in homicide rates in municipalities the Northeast region, which is the poorest region of the country and most affected by the policy expansion. We estimate that helping a municipality increase from zero electricity coverage to full coverage reduces homicide rates by 92 per 100,000 inhabitants. This is equivalent to moving a municipality that is at the 99th percentile to the median (zero) of the crime distribution across municipalities. In addition, we perform placebo exercises using sub-samples of predominantly urban municipalities. The results increase our confidence in the IV strategy since our primary results were from areas with a larger percentage of rural population, as should be expected by the policy.

Conclusions

This study contributes to the extant literature by investigating the effects of lighting on homicides in a different context, rural areas of a developing country (Brazil).

     

A study on the effects of degradation and template concentration on the amplification efficiency of the STR Miniplex primer sets

In forensic DNA analysis, the samples recovered from the crime scene are often highly degraded leading to poor PCR amplification of the larger sized STR loci. To avoid this problem, we have developed STR markers with redesigned primer sequences called "Miniplexes" to produce smaller amplicons. To assess the effectiveness of these kits, we have tested these primer sets with enzymatically degraded DNA and compared the amplifications to a commercial kit. We also conducted sensitivity and peak balance studies of three Miniplex sets. Lastly, we report a case study on two human skeletal remain samples collected from different environmental conditions. In both types of degraded DNA, the Miniplex primer sets were capable of producing more complete profiles when compared to the larger sized amplicons from the commercial kit. Correct genotypes were obtained at template concentrations as low as 31 pg/25 microL. Overall, our data confirm that our redesigned primers can increase the probability of obtaining a usable profile in situations where standard kits fail.     

A cross-cultural comparison of sociopsychological factors in alcohol use among adolescents in Israel,France, and the United States

The correlates of alcohol use by adolescents are compared in three cultures with different prevalences of alcohol use: France, with high prevalence; Israel, with low prevalence; and the United States, in the middle. In all three countries, significant others, parents and peers, are more powerful predictors of alcohol use than are the adolescent's personal attributes, such as attitudes, behaviors, and demographic characteristics. Cross-cultural differences appear in the relative importance of parents and peers and in the structure of influence of parents and peers as role models. Parents are more important role models in Israel than in the other two cultures, while peers are more important in the United States than in France or in Israel.This research was partially supported by Research Grants DA01902, DA00064, and Research Scientist Grant K05-DA00081 from the National Institute on Drug Abuse, and by the Center for SocioCultural Research on Drug Use, Columbia University.Received Ph.D. from Stanford University.

Objective measurement of dental color for age estimation by spectroradiometry

Age-related changes in tooth color have been described previously, however, the use of dental color for age estimation in forensic odontology has been limited due to the difficulty of measuring color objectively. This study presents an objective method for determining dental color to estimate the age of an individual. Dentine color in 250 teeth from patients ranging in age from 10 to 89 years was determined by spectroradiometry. Color measurements were performed as suggested in the CIE 1931 (International Commission on Illumination). Chromaticity coordinates (x, y, z), luminance (Y), whiteness index (WIC, Z%, WIC) and yellowness index (YI) were obtained. Correlations between these colorimetric variables and aging were established by linear regression analyses. All the variables fit the mathematical model with correlation coefficients ranging from 0.53 to 0.75. This method of color measurement produced an expected associated error of calibration averaging 13.7 years about the mean estimated values, at a 70% level of confidence. Two different multiple regression models for dental age estimation were tested, and variables that made the greatest contributions to age calculation were identified. To determine the effect of postmortem interval on tooth color and its influence in age estimation, 37 teeth obtained from human skeletal remains buried during an interval ranging from 21 to 37 years were also studied. In this material, the correlation between age and dental color measured by spectroradiometry was weaker than in fresh extracted teeth.It is concluded that determination of dentine color by spectroradiometry is a potentially useful objective method to estimate age in forensic studies in combination with other methods.     

The Evolving Matrix of Environmental Federalism and Intergovernmental Relationships

Using Daniel Elazar's metaphor of federalism as a matrix, asexpanded by Robert Agranoff, this article explores how stateand national political and administrative actors continue toredefine environmental federalism. The willingness of statesto sue the U.S. Environmental Protection Agency (EPA) over concernsthat the agency is not protecting the environment illustratesthe political and legal spotlight under which the matrix evolves.Outside the public purview, EPA and state environmental programadministrators attempted to shore up programs rocked by reducedbudgets and shifting priorities, while also adjusting to a newsystem of federal-state partnerships, the National EnvironmentalPerformance Partnership System.     

The social context of teenage childbearing: Effects on the infant's care-giving environment

The effects of maternal age and the social context on the home environment, and maternal behaviors of adolescent and older mothers, as well as the stability of the care-giving environment, were studied. Fifty low-middle socioeconomic status (SES), primiparous, Caucasian mothers and their fullterm healthy infants were included. At four months, support systems and life stress were assessed, as well as the home environment and maternal behaviors. At two years, a similar home visit was conducted in a subsample. Adolescent mothers had less education, lower SES, and a different child care support system. They also differed in the home environment and maternal behaviors at four months. Some of these differences disappeared when maternal education and SES, or child care support and life stress, were controlled. Moderate correlations were observed between four months and two years home environment and maternal verbalizations. Thus, a combination of maternal age and other social factors mediate the negative characteristics of the adolescent mother's care-giving environment, which is relatively stable during the infancy period.Received Ph.

The Voting Rights Act and Hispanic Political Representation in the Southwest

Extensions of the Voting Rights Act (VRA) in 1970 and 1975 expandedcoverage to the southwestern United States and included provisionsfor non-English speaking minorities. In the South, the VRA hadthe effect of increasing the number of black voters and electedofficials. In this article, we examine the changes in numbersof Mexican American and other Hispanic elected officials inthe five southwestern states for federal, state, and local officesduring the eleven-year period of 1973–1984. Gains occurredduring the period, although they were uneven across the statesand for different types of offices. The VRA served to removethe more blatant obstacles to electoral participation, but thelaw's fullest impact has also required effective political mobilizationby Hispanic organizations to increase voter registration andproduce a conducive environment for Hispanics to seek and winelective positions.
