The Gendered Face of Partisan Politics: Consequences of Facial Sex Typicality for Vote Choice

Facial cues are consequential for voters’ behavior at the polls. Yet the facial cues that are associated with vote choice remain under-examined. We predicted that vote choice judgments rely, in part, on the sex typicality of facial cues (i.e., the degree of facial masculinity and femininity) that vary as a function of candidate gender and partisan identification. Stimuli included image pairs of winners and runners-up in the elections for the 111th U.S. House of Representatives. In Study 1, we found that female Republican candidates who appeared relatively more feminine and male Republican candidates who looked relatively less masculine in their appearance were more likely to win their election. Democratic candidates’ electoral success was not related to their sex typicality. In Study 2, we found that relatively masculine-appearing Democrats and feminine-appearing Republicans were more likely to be selected in a hypothetical vote choice task. Implications for U.S. partisan politics are discussed.     

Forensic Identification of Blood in the Presence of Contaminations Using Raman Microspectroscopy Coupled with Advanced Statistics: Effect of Sand,Dust, and Soil

Body fluid traces recovered at crime scenes are among the most common and important types of forensic evidence. However, the ability to characterize a biological stain at a crime scene nondestructively has not yet been demonstrated. Here, we expand the Raman spectroscopic approach for the identification of dry traces of pure body fluids to address the problem of heterogeneous contamination, which can impair the performance of conventional methods. The concept of multidimensional Raman signatures was utilized for the identification of blood in dry traces contaminated with sand, dust, and soil. Multiple Raman spectra were acquired from the samples via automatic scanning, and the contribution of blood was evaluated through the fitting quality using spectroscopic signature components. The spatial mapping technique allowed for detection of “hot spots” dominated by blood contribution. The proposed method has great potential for blood identification in highly contaminated samples.     

Do Masculine Names Help Female Lawyers Become Judges? Evidence from South Carolina

This paper provides the first empirical test of the Portia Hypothesis:Females with masculine monikers are more successful in legalcareers. Utilizing South Carolina microdata, we look for correlationbetween an individual's advancement to a judgeship and his/hername's masculinity, which we construct from the joint empiricaldistribution of names and gender in the state's entire populationof registered voters. We find robust evidence that nominallymasculine females are favored over other females. Hence, ourresults support the Portia Hypothesis.     

The 2018 California Wildfires: Integration of Rapid DNA to Dramatically Accelerate Victim Identification

In November 2018, Butte County, California, was decimated by the Camp Fire, the deadliest wildfire in state history. Over 150,000 acres were destroyed, and at its peak, the fire consumed eighty acres per minute. The speed and intensity of the oncoming flames killed scores of people, and weeks before the fire was contained, first responders began searching through the rubble of 18,804 residences and commercial buildings. As with most mass disasters, conventional identification modalities (e.g., fingerprints, odontology, hardware) were utilized to identify victims. The intensity and duration of the fire severely degraded most of the remains, and these approaches were useful in only 22 of 84 cases. In the past, the remaining cases would have been subjected to conventional DNA analysis, which may have required months to years. Instead, Rapid DNA technology was utilized (in a rented recreational vehicle outside the Sacramento morgue) in the victim identification effort. Sixty-nine sets of remains were subjected to Rapid DNA Identification and, of these, 62 (89.9%) generated short tandem repeat profiles that were subjected to familial searching; essentially all these profiles were produced within hours of sample receipt. Samples successfully utilized for DNA identification included blood, bone, liver, muscle, soft tissue of unknown origin, and brain. In tandem with processing of 255 family reference samples, 58 victims were identified. This work represents the first use of Rapid DNA Identification in a mass casualty event, and the results support the use of Rapid DNA as an integrated tool with conventional disaster victim identification modalities.     

A Reevaluation of the Effects of State and ACA Dependent Coverage Mandates on Health Insurance Coverage

We study state and federal health insurance coverage mandates for young adults. Despite consistent findings that the Affordable Care Act's (ACA) federal mandate was effective, research has disagreed on whether preexisting, state-level mandates were successful in increasing coverage. We reconsider the issue with a new analytical perspective and newly available accurate data on state mandates. We show that the impact of the state mandates was substantive and concentrated among young adults between ages 19 and 23. Our estimates indicate that dependent coverage rose by 3.9 percentage points and overall coverage rose by 3.3 percentage points. Crowd-out of coverage through young adults’ own jobs was negligible. For those above 23, we find little evidence of changes in coverage. We incorporate these insights into analysis of the ACA's mandate, showing its effects were focused among those who were not eligible for state mandates, or were eligible but older than 23. Our results suggest that eligibility restrictions played important roles in limiting the scope of the state mandates, but they can be practical and effective tools for policymakers looking to ensure or expand coverage for young adults in the face of uncertainty about the ACA.
