A Comparison of Criminological and Public Health Models: Geographic and Social Diversity Associated with Methamphetamine Laboratory Seizures

In the 1990s methamphetamine (meth) emerged as a significant drug problem in the United States. Along with more widespread meth use was a growing pattern of localized production of the drug in small-scale clandestine laboratories, creating public health issues beyond the drug’s direct harms to the health of users. Early efforts in analyzing aggregate patterns of meth lab production across communities suggest this phenomenon is different from other types of crime and drug problems, showing distinctive geographic patterns and different causal/etiological dynamics. This paper assesses the viability of public health outcomes as predictors of methamphetamine laboratory problems and compares them with traditional criminological predictors as explanations for aggregate patterns in meth lab problems across U.S. counties. It documents how local variations in meth production are different from other types of crime patterns and identifies whether geographic variations in local meth labs might be more effectively predicted and explained in public health terms.     

The evolution of an innovation: variations in medicaid managed care program extensiveness

This article utilizes a theoretical framework of policy innovation, diffusion, and reinvention to investigate the evolving nature of Medicaid managed care programs over time. By estimating two separate models, one for primary care case management (PCCM) and a second for risk-based program enrollment, this study seeks to disentangle two different paths of learning (internal and external), investigate the potential effects of vertical diffusion of policy, and examine the impact of internal state characteristics on the extent of Medicaid managed care. With respect to diffusion and learning, the data reveal that earlier adopters implement more extensive programs. The data fail to reveal much internal learning, although there is evidence of some. External impacts are clear: managed care enrollments in neighboring states and changes in the federal waiver process affect states' decisions. Other policy choices are important: states with more generous Medicaid eligibility rules implement more extensive managed care programs. Complementing other studies of Medicaid, we find that politics and economics make a difference for the extent of managed care programs; unlike other Medicaid studies, we find no effect of race and ethnicity.     

Divided we vote

Divided government is known to correlate with limited government, but less is understood about the empirical conditions that lead to divided government. This paper estimates the determinants of continuous and categorical measures of divided government in an empirical macro political economy model using 30 years of data from the American states. Voters support more divided government after increased government spending per dollar of tax revenues, but more unified government after worsening incomes and unemployment rates. Only conditional support is found for the strategic-moderating theory (Alesina and Rosenthal in Econometrica 64(6):1311–1341, 1996) that focuses purely on midterm cycles and split-ticket voting absent economic conditions.     

Infrared spectroscopic imaging for noninvasive detection of latent fingerprints

The capability of Fourier transform infrared (FTIR) spectroscopic imaging to provide detailed images of unprocessed latent fingerprints while also preserving important trace evidence is demonstrated. Unprocessed fingerprints were developed on various porous and nonporous substrates. Data-processing methods used to extract the latent fingerprint ridge pattern from the background material included basic infrared spectroscopic band intensities, addition and subtraction of band intensity measurements, principal components analysis (PCA) and calculation of second derivative band intensities, as well as combinations of these various techniques. Additionally, trace evidence within the fingerprints was recovered and identified.     

Violence and Mental Illness: A New Analytic Approach

Empirical studies of violence and mental illness have used many different methods. Current state-of-the-art methods gather information from both subject and collateral interviews as well as official records. Typically these sources are treated as additive. Any report of a violent incident from any source is treated as true and all reported incidents are added to generate estimates of frequency. This paper presents a new statistical technique that uses the level of agreement between the sources of data to adjust those estimates. The evidence suggests that, although the additive technique for using multiple sources correctly estimates how many people are involved, it substantially underestimates the number of incidents. The new technique substantially reduces both false negatives and false positives.

“Ain't Making It in America”: The Economic Characteristics of African Immigrants in North Carolina,USA

This study interviewed 350 African immigrants in North Carolina (NC) to shed light on their economic conditions. It focused primarily on their labor force participation and incomes for the period 2004–2014. The findings showed that both structural changes in NC's economy and prejudicial experiences within the labor force were the most important forces that undermined the economic ambitions of the Africans. The study also yielded a complex picture and raised some questions about the resettlement outcome of African immigrants in the United States.     

Inverse Productivity or Inverse Efficiency? Evidence from Mexico

Using a unique panel data set from rural Mexico, we find strong evidence of a negative relationship between farm size and both productivity and technical efficiency: large farms not only have a lower value of output per hectare than small farms, they also produce further from the efficiency frontier. Our findings suggest that, in spite of the ongoing transformation of agricultural supply chains and economists’ recommendations for small farmers to exit crop production, there may be sustained advantages for smallholder farms. Our analysis offers new insights into inverse-farm size relationship, the productivity–efficiency relationship, and the use of stochastic frontier techniques.
