Composting pilot begins at Andrews Commons Brandishing

Under the compost initiative, more dining items are compostable and there are new compost bins. For the first two weeks of the initiative, student volunteers will monitor bins to help students sort their waste.

Composting pilot will cost $9,000 up front but save University money long term By KATE TALERICO SENIOR STAFF WRITER

The University will kickstart an 11week composting pilot program at Andrews Commons Tuesday, prefacing a collaborative effort by the Office

of Energy and Environment, Brown University Dining Services and the Department of Facilities Management to bring mandatory composting to every dining hall by January 2016. The push for composting follows the July 2014 passage of the Rhode Island Refuse Disposal Law, which requires institutions to compost if they generate more than two tons of organic waste per week. The requirements will take effect Jan. 1, 2016. Additionally, the Brown Student

Compost Initiative, SCRAP, submitted a report to the University last year detailing the need for a campus-wide composting program. The Sustainability Strategic Planning and Advisory Committee considered the report in its eventual plans to implement composting, said Jasmine Fuller ’15, a member of SCRAP. The effort to implement composting “couples with our sustainability initiative,” said Jessica Berry, sustainability program manager. “There’s a

lot of waste produced in terms of togo containers and coffee cups. We’re looking at reducing those, and if we can’t reduce, then getting them out of the landfill stream.” Under the program, items at Andrews that were once non-compostable, like utensils and cups, will be replaced by items made of compostable materials, Berry said. “It’s an added cost, but it significantly diverts a lot of waste.” The pilot alone, which runs through May 15, will cost the University $9,000, Berry said, adding that a third of that bidget goes toward capital costs and the rest toward operations. But composting will reduce overall costs for the University, said Haily Tran ’16, a sustainability intern in the Office of Sustainable Energy and Environmental Initiatives. The Compost Plant, a local compostable materials collection company, will charge a fixed sum to pick up the University’s compost, “but it’s less than we pay Waste Management to take our trash away, since they take it based upon weight,” Tran said. Currently, the Compost Plant only offers collection services. The company brings waste to Earth Care Farm, the only facility in Rhode Island that » See COMPOST, page 4

weapon, man assaults student

Incident remains under investigation by Providence Police Department By ALIZA REISNER SENIOR STAFF WRITER

An unknown male opened the drivers’ door of a student’s car and displayed a firearm at about 9:40 p.m. March 1, according to a crime alert sent by the Department of Public Safety. The victim drove away unharmed, the email reported. The student was parked on Angell Street between Thayer Street and Brown Street. The suspect was described as a white man between the ages of 20 and 25 wearing a black knit hat. Paul Shanley, deputy chief of DPS, could not be reached before press time. The incident is under investigation by the Providence Police Department, according to the crime alert.

Minority populations face Study explores neuroscience of extroversion high juvenile detention rates Researchers examine

Nonprofit organization Kids Count favors community action to reduce racial disparity By LINDSAY GANTZ STAFF WRITER

PLAYGROUND TO PRISON This series explores the racial dynamics of Rhode Island’s school-to-prison pipeline. This story, the second of three, examines disproportionate juvenile detention rates that black and Hispanic students encounter. Black males in Rhode Island were 9.3 times as likely to end up in juvenile detention centers than their white peers in 2013, according to “The School-toPrison Pipeline in Black and White,” a report ­released by the American Civil Liberties Union of Rhode Island Feb. 19. The information reported by the ACLU comes from data collected by Rhode Island Kids Count, a nonprofit organization that advocates better conditions for children in the state. The number of minority youth referred to Family Court and ultimately

placed into detention centers in 2013 was disproportionate to Rhode Island’s racial and ethnic composition, according to Kids Count’s 2014 annual report. Though the 2013 child population in Rhode Island was 64 percent white, whites accounted for just 25 percent of adjudicated youth at the Rhode Island Training School for that year. The remaining 75 percent adjudicated were primarily Hispanic and black, according to the Kids Count report, while the child population was 21 percent Hispanic and 6 percent black in 2013. Minorities were also punished more severely than whites for juvenile offenses of the same magnitude. “Specifically, what Kids Count has found is a higher number of black youth in front of a judge” than their proportion of the population, said Hillary Davis, policy associate at the ACLU of Rhode Island. Forty-nine percent of juveniles referred to the Family Court in 2013 were white, 19 percent were black, 18 percent were Hispanic, 1 percent were Asian and 13 percent were other or unknown, according to Kids Count data.

possible link between personality, gray matter concentrations By ELENA WEISSMANN STAFF WRITER

An extrovert can be classified as one of two types: the “affiliative” people person who finds reward in connecting with others and the “agentic” high flyer who pursues social interactions in order to best advance his or her own goals. Differences between these two types may lie not just in personality but also deep within the skull, according to a study done by University researchers. Published in the February issue of the journal Cognitive, Affective and Behavioral Neuroscience, the report examines the similarities and differences in neuroanatomy between the two extrovert personality types. “We show that there may be a link between personality and brain anatomy,” said Erica Grodin GS, the lead author of the study. “People who score high on agentic extroversion

SCIENCE & RESEARCH

have these increases in specific grey matter regions that the affiliative social extroverts don’t necessarily have.” In order to separate participants into the two pools of extroverts, the researchers first had participants complete the Multidimensional Personality Questionnaire, a survey that asks questions about levels of sociability and assertiveness, Grodin said. The researchers then took “structural MRI scans of 83 men and women ranging in age from 18 to 54,” according to a University press release. After the MRI, the researchers used “voxel-based morphometry,” a neuroimaging analysis technique that separates brain matter from cerebral spinal fluid, a brain component that was not necessary for the analysis, Grodin said. By combining the personality ratings with the anatomical data, the researchers compared volumetric differences in grey matter between the two groups. As they had expected, they found that both types exhibit a greater-thanaverage volume of grey matter in the medial orbitofrontal cortex, an area involved in information processing and reward value, Grodin said. Previous literature has shown the medial orbitofrontal cortex to be the

“extroversion region,” Grodin said. But this study identified other areas of the brain that are associated with agentic, but not affiliative, extroversion. Their results show that agentic extroverts boast more grey matter volume in the parahippocampal gyrus, the precentral gyrus, the nucleus accumbens and the caudate, according to the release. “These regions are either involved in memory and reward or voluntary movement towards goal-directed action, so these are regions that will be activated when you’re trying to attain something,” Grodin said. “That’s a feature of agentic extroverts.” “It was logical that these regions would be bigger as they both are involved in cognitive control, feedbackdirected behavior and exploration,” said Joseph Austerweil, assistant professor of cognitive, linguistic and psychological sciences, who was not involved in the study. “As agentic extroverts are more assertive and confident, they’re more likely to go out and explore. That can lead to future connections with those brain regions,” he added. But larger volumes in certain brain regions do not necessarily lead » See EXTROVERT, page 2
