(Press-News.org) Researchers at the University of Pennsylvania have found a three to five percent reduction in the probability of criminal recidivism among a sample of juveniles arrested for felony drug offenses, some of whom were processed as adults due to their age at the time of their arrests.
In a study published in the Journal of Research in Crime and Delinquency, Charles Loeffler, an assistant professor of criminology in the School of Arts & Sciences and Ben Grunwald, a doctoral candidate in the criminology department, analyzed the effect of processing juveniles as adults using a regression discontinuity design.
The study, titled "Processed as an Adult: A Regression Discontinuity Estimate of the Crime Effects of Charging Nontransfer Juveniles as Adults," estimated the effect of the juvenile and adult justice systems on recidivism for non-transfer-eligible juvenile offenders by comparing the four year re-offending rates of juveniles arrested for drug distribution just a few weeks before and after they reached adulthood.
The results suggested that processing these juveniles as adults slightly reduced the probability of recidivism. Based on the rapid onset and limited change in size of the effects over a four-year follow-up and the concentration of the effects within a sub-group having the lowest risk of incarceration. The researchers attributed this finding to a combination of enhanced deterrence and incapacitation in the adult justice system.
"These results suggest that processing juveniles in the adult system may not uniformly increase offending, as many scholars have thought, and may actually reduce offending in some circumstances," Loeffler said.
The study examined the recidivism of felony drug offenders arrested a few weeks before their 17th birthday who were processed in the juvenile justice system and those arrested just a few weeks after their 17th birthday who were processed in the adult criminal justice system.
Past studies have found that serious juvenile offenders transferred into the adult system as part of automatic, presumptive or discretionary transfer mechanisms re-offend much more often than similar juvenile offenders retained in the juvenile system. Such findings have led scholars and policymakers to conclude that exposing youth to the adult justice system exacerbates criminal offending.
However, Loeffler said that the existing empirical literature is primarily focused on the most serious or frequent juvenile offenders. There is relatively little information on the effects of processing more typical juveniles in the adult system. Similarly, the existing literature has used research designs that make it difficult to separate the effects of processing juveniles as adults from pre-existing differences in the risk of recidivism between juveniles who are processed in the two different legal systems.
The results of Loeffler and Grunwald's study, which differed from some of the early empirical literature examining the effects of processing juveniles as adults, adds to a growing number of studies observing that offending among older juveniles is relatively insensitive to the exact legal system in which they are prosecuted. The researchers attributed this divergence between earlier and newer studies to both the samples of offenders examined and the estimation strategies employed.

For engine designers in the digital age, time is money. And that time is measured in computer cycles.
Researchers at the U.S. Department of Energy's Argonne National Laboratory are partnering with Convergent Science, Inc. (CSI), to speed up a key piece of modeling and simulation software to ensure those cycles are used as effectively as possible, reducing product development time and resulting in better engines and savings for consumers. The scale of the speed gains were recently demonstrated when researchers ran the largest engine simulation to date on more than 4,000 ...
Irvine, Calif., June 9 -- Brain inflammation caused by chronic nerve pain alters activity in regions that regulate mood and motivation, suggesting for the first time that a direct biophysical link exists between long-term pain and the depression, anxiety and substance abuse seen in more than half of these patients, UC Irvine and UCLA researchers report.
This breakthrough finding also points to new approaches for treating chronic pain, which is second only to bipolar disorder among illness-related causes of suicide. About a quarter of Americans suffer from chronic pain, ...
MAYWOOD, Ill. -- Brain lesions in children can be especially challenging to diagnose, according to a report in the journal Frontiers in Neurology by a multidisciplinary team of Loyola University Medical Center physicians.
Lesions include tumors, abnormal blood vessel formations and abscesses and inflammation due to infections.
In the pediatric population, such lesions 'can have a large variety of underlying etiologies (causes), which can be challenging to differentiate on neuroimaging,' lead author Marisa McGinley, M.D., and colleagues report.
The Loyola physicians ...
Promotion of handwashing with soap and weekly nail clipping are both successful strategies to decrease intestinal parasite re-infection rates in school aged Ethiopian children, according to a study published by Mahmud Abdulkader Mahmud and colleagues from Mekelle University, Ethiopia, in this week's PLOS Medicine.
The researchers reached these conclusions by conducting a cluster randomized controlled trial in which 367 parasite-negative school-aged children in Northern Ethiopia were randomly assigned to either the handwashing intervention, the nail clipping intervention, ...
Tropical cyclones are not too common in the Arabian Sea, but tropical cyclone 01A, now renamed Ashobaa, formed this week. NASA/JAXA's Global Precipitation Measurement or GPM core satellite flew over Ashobaa and gathered data that provided a 3-D look at the rainfall in the storm.
The GPM core observatory satellite flew over Ashobaa on the morning of June 8 at 0811 UTC (4:11 a.m. EDT). Tropical cyclone Ashobaa had sustained wind speeds of about 40 knots (46 mph) when the satellite passed overhead.
On June 9 at 0900 UTC (5 a.m. EDT), tropical cyclone Ashobaa had maximum ...
MADISON, Wis. -- Scientists have prior evidence that the hormone estrogen is a major driver in the growth of cervical cancer, but a new study examining genetic profiles of 128 clinical cases reached a surprising conclusion -- estrogen receptors all but vanish in cervical cancer tumors.
This counterintuitive finding, reported June 8 in the online Proceedings of the National Academy of Sciences, further bolsters the understanding of cervical cancer's progression and offers valuable new targets to fight the disease.

The economic impact of the Energy Department's National Renewable Energy Laboratory (NREL) was $872.3 million nationwide in fiscal year 2014, according to a study by the University of Colorado Boulder's Leeds School of Business.
The study estimates NREL's impact to Colorado's economy totaled $701 million, a decline of 1.6 percent from the prior year. The slight year-over-year drop was largely attributed to a decline in major construction spending that came as NREL completed the planned build-out of its sustainable campus.
Jefferson County, where the largest concentration ...
Two of our nation's most advanced wind energy research and test facilities have joined forces to help the wind energy industry improve the performance of wind turbine drivetrains and better understand how the turbines can integrate more effectively with the electrical grid.

DOWNERS GROVE, Ill. - June 9, 2015 - The percentage of U.S. female physician authors of original research in major gastroenterology journals has grown over time, yet the percentage of women in the senior author position remains lower than expected based on the proportion of female gastroenterologists in academia. A look at the evolution of gender in the GI publishing landscape is presented in "Female authorship in major academic gastroenterology journals: a look over 20 years," published in the June issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific ...
SAN FRANCISCO--Seismologists studying the recent dramatic upswing in earthquakes triggered by human activity want to clear up a few common misconceptions about the trend.
There is increasing evidence that these earthquakes are caused by injecting fluids from oil and gas operations deep into the earth. These human-caused earthquakes are sometimes called "induced earthquakes."
A Seismological Research Letters focus section to be published online June 10 addresses some common misconceptions about induced seismicity--the biggest of which is that it is primarily related ...
