Number of TAs fine, students say

The University is trying to take advantage of the uncertain economy to lower its energy costs. Facilities Management signed an agreement Wednesday with World Energy Solutions, a move that allows the University to lock in energy commodity prices as far as two years in advance, said Chris Powell, director of sustainable energy and environmental initiatives. Until now, the University has bought oil and gas up to a year in advance of when they would be needed, hoping to lock in prices while they were low. The new agreement, which Powell said is a “very significant” change for the University, allows it to expand that strategy, letting it invest in energy for as far ahead as 2010 using today’s prices. Powell said he expects prices will increase with time. World Energy operates a market for energy buyers and suppliers. It will work as a middleman between Brown and oil and gas suppliers, allowing a greater number of suppliers to bid as part of a reverse auction. Yet like any investment, this one is not without risks. Energy prices for this year were locked in June, mainly in response to fears that a continued upward trend in prices would force an expansion in the Facilities budget, Powell said. But when the economy and consumer demand turned south in recent weeks, energy prices started to fall below the cost the University bought energy at months ago. Although oil and gas prices have decreased significantly since June, the University will continue to pay at elevated rates until next year, Powell said. “Sometimes you win, sometimes you lose,” he said. “We don’t have a crystal ball.” He added that the University saw the opposite effect last year, saving money by locking in very low prices before costs surged. On balance, Powell said locking in future prices saves the University money. Finding new ways to keep energy costs under control has been a priority for several years. The University’s heating costs are up 25 percent this fiscal year, with the total energy budget now reaching $23 million. The University saved about $600,000 by switching most of its heating operations last year from oil to natural gas, The Herald reported in February. Unlike the heating oil the University once used, natural gas is listed on the New York Mercantile Exchange, a large commodities market that Powell said gives Brown access to many more suppliers, helping lower costs. Facilities Management also spent $800,000 to replace 1,400 steam traps on campus in the past year, a project that is expected to save the Univer-

Spanish bank to help fund scholar visits By George Miller Senior Staff Writer

University officials and the chair of Banco Santander, Spain’s largest bank, will sign an agreement today to create a series of meetings that will bring together rising and more established scholars from around the world to campus. The International Advanced Research Institutes will launch in June 2009 and continue in subsequent Junes, according to a University statement. In addition to creating an “intensive workshop-like setting” at each of these institutes, the agreement will create grants for Brown students to study abroad, student internships at world banks affiliated with Banco Santander and a Spanish language program offered in conjunction with the Cervantes

in organizing such a program to create a proposal for this summer’s sessions. Ileana Porras, a visiting professor at the Watson Institute, will direct the institutes this summer. The institutes are designed to help scholars from poorly represented areas of the world be heard, according the International Affairs Web site. Banco Santander will support the agreement through the global division of Santander Universities, which was founded in 1996. The group currently supports over 700 academic institutions, according to Santander’s Web site. A signing ceremony today between Provost David Kertzer ’69 P’95 P’98 and Banco Santander chairman Emilio Botin P’86 P’87 will make the partnership official.

From prof ’s lab, a way to undress you electronically By Gaurie Tilak Senior Staff Writer

Professor of Computer Science Michael Black has the decency not to undress you with his eyes. But he’s more than happy to do it with his computer. Black and Alexandru Balan GS have developed a program that allows a computer to determine the shape of a person’s body based on images of the person wearing clothes.

FEATURE The two developed the program to meet a need for realistic models of the human body. “We’ve been working on tracking humans in video for a number of years,” Black said. “But until now, our models of the human body looked like the tin man from ‘The Wizard of Oz.’ ” The technology could have applications in several fields, includ-

Institute, a nonprofit created by the Spanish government. “We expect the (institutes) to make a significant contribution to global research through transnational academic collaboration,” David Kennedy ’76, vice president for international affairs, said in the statement. The institutes will contribute to the University’s stated goal of gaining a greater international profile, noted Kennedy, who is also the interim director of the Watson Institute for International Studies. The institutes, lasting one to four weeks, will be “immersion experiences,” according to the call for proposals on the International Affairs Web site. The programs should focus on training and collaboration between new and old scholars, the document states. It calls for departments interested

Despite some controversy about the supply of teaching assistants for undergraduate courses, a recent Herald poll found that the majority of undergraduate students are satisfied with the number of TAs in their classes. Of students polled, 76.6 percent reported being either “very” or “somewhat satisfied” with the number of TAs in their courses, with 34.1 percent saying they were “very satisfied.” Only 17.9 percent reported being “somewhat” or “very dissatisfied.” Students, in general, weren’t surprised by these results. Benjamin Friedman ’09 said respondents “are going to answer that they’re satisfied because most students don’t talk to their TAs.” He speculated that the results would have been different if students wanted one-on-one interaction with their TAs. Elizabeth Schaja ’11, who said she was “pretty satisfied” with the number of TAs in her courses, also speculated that poll respondents would say they were satisfied because they don’t go to discussion sections. She said she has classes for which section is optional, and “usually people don’t go.” Friedman, who has worked as a TA in the Department of Geology, said that when he offered to give help or review sessions, “barely anyone reached out.” “I think the big problem is that students don’t seek out TAs enough,” he said. The poll also showed that first-
