Study on intermittency in gang membership underscores value of preventing youth from rejoining gangs

2021-05-21
(Press-News.org) Research has shown that joining a gang is associated with increased criminal behavior. A new study examined whether the intermittent nature of gang membership affects offending. Researchers sought to determine whether the association with increased offending was a consistent attribute or, since people enter and exit and re-enter gangs, whether the intermittent nature of membership affected members' likelihood of offending. The study found that first-time membership was associated with increases in criminal behavior from when gang members were not in gangs, and that joining for a second time significantly raised the likelihood of offending, including more violent behavior.

The study, by researchers at the University of Texas at San Antonio and the University of Maryland, appears in Criminology, a publication of the American Society of Criminology.

The results suggest that gang membership, whether as a new or a repeat experience, is a salient life event and that intermittency can disrupt individuals' offending profiles, according to coauthors Megan Bears Augustyn, associate professor of criminology and criminal justice at the University of Texas at San Antonio, and Jean McGloin, professor of criminology and criminal justice at the University of Maryland. Augustyn and McGloin say that based on their documentation of changes in offending behavior that parallel changes in individuals' self-identification as gang members, interventions should take into account the intermittency of gang membership.

Although past researcher has acknowledged the intermittency of gang membership, studies have not investigated whether different stages of gang membership are associated with different offending patterns. In this study, researchers used data from the Rochester Youth Development Study, which examined the development of antisocial behavior among 1,000 youth who were representative of the seventh- and eighth-grade public school population of Rochester, NY, in 1988. The 177 youth included in this study self-reported gang membership; of these, 53 said they had joined a gang for the second time.

The youth were predominantly Black (67 percent), as well as Hispanic (17 percent) and White (16 percent). Most of the youth (73 percent) were male, only 36 percent lived with both biological parents at the start of the study, and most were economically disadvantaged. The average age of participants at the beginning of the study was 13.9 years old. Youth were interviewed up to nine times over about four and a half years.

Joining a gang for the first time was associated with increases in general offending behavior, as well as violence, property crime, and drug sales, when compared to pre-gang time periods. Joining a gang for the second time was also associated with significant increases in general offending, violence, and drug sales (though not property crime), when compared to time out of the gang after first-time membership.

The study also found that joining a gang for the second time had an indirect path to offending via delinquent peers, but not deviant values or drug use. Deviant values were measured as youth's level of agreement with 10 offenses (e.g., stealing something worth $100 or more). This path was not observed in first-time gang membership. This led the researchers to conclude that there are significant changes in individuals' offending behavior both when they first join a gang and when they later join a gang.

The authors note that the gang members they studied came from one urban jurisdiction and joined gangs during adolescence, raising questions about generalizability to other areas and other ages. In addition, the study lacked information from all nine interviews on a number of factors that could explain individuals' reasons for joining gangs. Finally, the study was unable to deconstruct joining a gang for the second time by whether an individual went back to the same gang or joined a different one.

The authors say their research underscores the importance of not only supporting youth's decision to leave a gang in the first place, but also preventing youth from rejoining a gang while navigating the disengagement process since this has significant implications for criminal behavior and the associated snares.

First-of-its-kind flower smells like dead insects to imprison 'coffin flies'

First-of-its-kind flower smells like dead insects to imprison coffin flies
2021-05-21
The plant Aristolochia microstoma uses a unique trick: its flowers emit a fetid-musty scent that seems to mimic the smell of decomposing insects. Flies from the genus Megaselia (family Phoridae) likely get attracted to this smell while searching for insect corpses to mate over and lay their eggs in. When they enter a flower, they are imprisoned and first pollinate the female organs, before being covered with pollen by the male organs. The flower then releases them unharmed. "Here we show that the flowers of A. microstoma emit an unusual mix of volatiles that includes alkylpyrazines, which are otherwise rarely produced by flowering plants. Our results suggest that this is the first known case of a flower that tricks pollinators by smelling like dead and rotting insects rather than vertebrate ...

Doctors have nothing to fear from a central register of interests, say experts

2021-05-21
UK doctors have nothing to fear from the introduction of a central register listing money or benefits they receive in addition to their NHS salary, say experts today ahead of a public meeting on the issue hosted by the All-Party Parliamentary Group for First Do No Harm and The BMJ. Last year the Independent Medicines and Medical Devices Safety Review, chaired by Baroness Julia Cumberlege, investigated harmful side effects caused by the hormone pregnancy test Primodos, the anti-epileptic drug sodium valproate, and pelvic mesh. During the review, she heard from patients who were concerned that clinicians ...

Will COVID-19 eventually become just a seasonal nuisance?

2021-05-21
Within the next decade, the novel coronavirus responsible for COVID-19 could become little more than a nuisance, causing no more than common cold-like coughs and sniffles. That possible future is predicted by mathematical models that incorporate lessons learned from the current pandemic on how our body's immunity changes over time. Scientists at the University of Utah carried out the research, now published in the journal Viruses. "This shows a possible future that has not yet been fully addressed," says Fred Adler, PhD, professor of mathematics and ...

Scientists reveal structural details of how SARS-CoV-2 variants escape immune response

2021-05-21
LA JOLLA, CA--Fast-spreading variants of the COVID-19-causing coronavirus, SARS-CoV-2, carry mutations that enable the virus to escape some of the immune response created naturally or by vaccination. A new study from scientists at Scripps Research, along with collaborators in Germany and the Netherlands, has revealed key details of how these escape mutations work. The scientists, whose study appears in Science, used structural biology techniques to map at high resolution how important classes of neutralizing antibodies bind to the original pandemic ...

Researchers use environmental data to assess prostate cancer diagnosis factors

2021-05-20
Environmental quality is associated with advanced-stage prostate cancer at diagnosis, according to a new study by University of Illinois Chicago researchers.  Prostate cancer is up to 57% heritable, with the remainder attributed to environmental exposures. However, studies on those environmental factors and prostate cancer aggressiveness have previously been limited. For their study, "Association between environmental quality and prostate cancer at diagnosis," published in the journal Prostate Cancer and Prostatic Disease, researchers paired data from the environmental quality index, or EQI, and the Surveillance, ...

Study: Culture influences mask wearing

2021-05-20
Around the world and within the U.S., the percentage of people wearing masks during the Covid-19 pandemic has varied enormously. What explains this? A new study co-authored by an MIT faculty member finds that a public sense of "collectivism" clearly predicts mask usage, adding a cultural and psychological perspective to the issue. The study uses a series of datasets about mask usage and public attitudes, along with well-established empirical indices of collectivism, to evaluate the impact of those cultural differences on this element of the pandemic response. ...

Research suggests fly brains make predictions, possibly using universal design principles

Research suggests fly brains make predictions, possibly using universal design principles
2021-05-20
Flies predict changes in their visual environment in order to execute evasive maneuvers, according to new research from the University of Chicago. This reliance on predictive information to guide behavior suggests that prediction may be a general feature of animal nervous systems in supporting quick behavioral changes. The study was published on May 20 in PLOS Computational Biology. Animals use their sensory nervous systems to take in information about their environments and then carry out certain behaviors in response to what they detect. However, the nervous system takes time ...

Novel immune checkpoints have applications for cancer, autoimmune disease treatment

Novel immune checkpoints have applications for cancer, autoimmune disease treatment
2021-05-20
The immune system is a complex balancing act; if it overreacts or underreacts to foreign molecules, there can be serious health consequences. For cancer patients, tumor progression is often accompanied by immunosuppression, meaning their bodies can't fight off pathogens the way they should. By contrast, for people with autoimmune diseases like type 1 diabetes, rheumatoid arthritis, and multiple sclerosis, their immune systems overreact and attack the body itself. Both of these reactions are influenced by a series of molecular checkpoints found in both immune cells and cancer cells. In immune ...

What makes some oysters more resilient than others?

What makes some oysters more resilient than others?
2021-05-20
Oysters live and grow in saltwater. However, the saltiness of their habitat can change dramatically, especially where the mighty Mississippi River flows into the Gulf of Mexico. Louisiana oysters from the northern Gulf of Mexico may experience some of the lowest salinity in the world due to the influx of fresh water from the Mississippi River. In addition, increased rainfall and large-scale river diversions for coastal protection will bring more fresh water that does not bode well for the eastern oyster. New research led by Louisiana State University (LSU) alumna Joanna Griffiths from Portland, Oregon, and her faculty advisor ...

AI-enabled EKGs find difference between numerical age and biological age significantly affects health

2021-05-20
ROCHESTER, Minn. -- You might be older - or younger - than you think. A new study found that differences between a person's age in years and his or her biological age, as predicted by an artificial intelligence (AI)-enabled EKG, can provide measurable insights into health and longevity. The AI model accurately predicted the age of most subjects, with a mean age gap of 0.88 years between EKG age and actual age. However, a number of subjects had a gap that was much larger, either seemingly much older or much younger by EKG age. The likelihood to die during follow-up was much ...
