Domestic violence: “Once an abuser, always an abuser” not always true

lockwood.jpgPreliminary anthropology research in French Polynesia seems to confirm what psychology and sociology researchers have observed about domestic violence in general: There are two different types. One kind endures and escalates, while the other gradually fades away after a few years.

The findings are those of SMU’s Victoria Lockwood, who for three decades has studied the lives of women on the chain of South Pacific islands that includes the tropical paradise of Tahiti.

Few anthropologists study domestic violence. What Lockwood has found initially confirms the existence of “battering,” which is long-lived, versus “situational couple violence,” which is short-lived.

“If we don’t acknowledge there are two different kinds of domestic violence, then we’ll never understand what the causes are,” says Lockwood. “The causes are very different, so if we wish to devise policies or social programs, we need to be doing two different things to address the issues.”

Lockwood is a cultural anthropologist and associate professor in the Anthropology Department of SMU’s Dedman College. For 28 years she has studied the impact of modernization and globalization on the women of Tahiti and its tiny rural neighbors, Tubuai and Rurutu.

Lockwood’s research took a turn, however, when the women began disclosing that arguments with their husbands at times resulted in physical violence. The revelations intrigued Lockwood. Now she is investigating the prevalence, causes, meanings and consequences of domestic violence on its victims on the islands. The research is funded by a three-year, $128,000 grant from the National Science Foundation.

LockwoodPix.jpgLockwood leaves in June for a month-long stay on Tubuai and Rurutu. She first traveled there in 1981 as a graduate student for her doctoral degree at UCLA. In the past three decades Lockwood has made seven trips to the islands, in particular Tubuai. The most recent one was in 2005, when she conducted preliminary research, interviewing husbands and wives from 25 families about domestic violence in their lives.

“Because I’ve worked on this island so long, I know these families, and they’ve already talked to me about abuse,” Lockwood says.

What kind of domestic violence?
The islands are a fairly gender-egalitarian society, she says. Domestic violence is no more common there than anywhere else. The women expressed distress to Lockwood that their husbands hit them, but said the assaults gradually stop after the early years of marriage.

“If you ask the wives, ‘Has your husband ever hit you or shoved you or kicked you?’ the vast majority will say that it’s happened, and that they’ve probably done it themselves, but that it wasn’t a pattern,” Lockwood says. “They’ll say, ‘Oh, he had just lost his job or he was stressed out from this or that, and it doesn’t happen all the time, and it went away.’ If you asked them ‘Is this domestic violence?’ they would say, ‘No.'”

That’s not the stereotype of domestic violence, Lockwood notes, citing the widely held belief that one incident of abuse indicates more to come.

For example, consider talk-show host Oprah’s advice this spring to pop star Rihanna, telling her to break up with boyfriend Chris Brown because he would surely hit her again.

“The word on the street, at least in American society, is that domestic violence doesn’t go away, ‘Once an abuser, always an abuser,’ and that the abuse escalates over time,” Lockwood says. “But that wasn’t the case in Tahiti. And that’s what got me interested in looking at the issue in Tahitian society.”

Psychologists and sociologists have reported the distinction between short- versus long-lived domestic abuse for about 15 years. They describe situational couple violence as sporadic domestic abuse that occurs early in a marriage as a couple attempts to work out balance-of-power issues and decision-making. The violence is initiated by either the husband or wife, then fades away.

Battering is typically enduring, and the husband is normally the aggressor. The violence usually escalates, with the husband obsessed to control every aspect of his wife’s behavior, using verbal as well as physical tactics, Lockwood says.

“In Tubuai, a lot of young couples describe the early years of marriage as very rocky, very difficult, and then things get much better,” she says.

Anthropologically, Lockwood says, the work is relevant to the study of violence in general.

“In a lot of societies, various acts of violence, even between spouses, are considered to be OK and legitimate. In some societies that’s not the case, and other acts are considered terrible and horrible. But it’s all violence,” Lockwood says. “I hope to understand more about how different cultures define what violence is, and what is an appropriate relationship between husbands and wives.” — Margaret Allen

Before God particle, scientists must learn soul of new machine

After a huge success in first testing, followed by a very public meltdown last September, the Large Hadron Collider may be ready for action again as early as June.

But before the science can proceed, the world’s scientists must come to terms with the complex organism they have created, says one project manager.

“We will have to understand the detector first,” says Ryszard Stroynowski, chair and professor of physics at SMU.

Stroynowski is U.S. Coordinator for the Liquid Argon Calorimeter, the literal and experimental heart of ATLAS, the largest particle detector in the LHC array.

The first priority for operation of the ATLAS detector is “to get all those billions of elements to work together in synch again,” Stroynowski says. “We want to see during the summer whether the circulating beam will induce any noise in the system.”

Stroynowski leads an SMU delegation that includes Fredrick Olness, professor of physics, and Robert Kehoe and Jingbo Ye, assistant professors of physics, all in Dedman College. Kehoe is currently at CERN for his research.

The SMU team is focusing on three projects in parallel:

  • improvements of the graphic and software interfaces for control and monitoring of the detector and of the quality of its data
  • preparation of the software packages to analyze the data
  • design and prototyping of the modifications of the readout electronics that will be needed for future upgrades of the experiment to much higher-intensity beams — a six-year research and development project led by Jingbo Ye in SMU’s Physics Electronics Lab.

The LHC is considered the world’s largest physics experiment. The particle accelerator is a 27-kilometer circular tunnel that lies 100 meters underground near Geneva on the French-Swiss border. It uses a magnetic field to propel high-energy protons into each other.

A mechanical failure in September 2008 damaged 53 of the super-sized magnets that power and focus the accelerator’s beams. The final replacement magnet was lowered into place April 30. Repairs in the tunnel now focus on connecting the magnets together and installing new safety and monitoring systems to prevent similar incidents from happening again.

In addition, the 37 damaged magnets that were replaced by spares will be refurbished to serve as spares themselves. Sixteen magnets sustained only minimal damage and were repaired and reinstalled.

The earlier malfunction has resulted in a frustrating wait — one that has had a “rather demoralizing” effect on the students and postdoctoral fellows whose time at the LHC may come and go during downtime, Stroynowski says. Yet the importance of protecting the vast high-energy array from future trauma can’t be overstated, and “the goal is worth the wait, as the payoff may be enormous,” he says.

Scientists and technicians at the European Organization for Nuclear Research — called by its acronym, CERN — in Geneva have maintained an aggressive rehabilitation schedule. The ATLAS detector itself was closed on May 5, marking an end to checks and re-checks of the electronics, cables and other connections. Repairs to the accelerator’s underground ring are scheduled to be completed at the end of May.

Beams will start in June, initially at a relatively low 450 gigaelectron volts (GeV) per beam to ensure the integrity of the new parts and connections. Scientists will raise the energy over a couple of days to 2 teraelectron volts (TeV) per beam, and finally to the LHC’s target operational level of 5 TeV per beam.

The ATLAS team will start taking shifts in July and expects to have useful data starting in October 2009, Stroynowski says. The LHC will then run continuously for 11 months.

Stroynowski says he doesn’t expect any major discoveries by this time next year, but that he hopes “significant results” will come early in 2011.

The LHC’s proton collisions release even smaller pieces of matter, and the Atlas particle detector helps measure the tracks they leave. The huge, international project is directed at finding the “Higgs boson,” a subatomic “God particle” that physicists believe could help explain the origin of our Universe.

The theory behind the Higgs boson holds that all particles had no mass just after the “Big Bang.” As the Universe cooled and the temperature fell below a critical value, an invisible force field composed of subatomic particles called the “Higgs boson” developed throughout the cosmos. Particles that interact with the field gain mass and particles that never interact have no mass. But the theory remains unproven because no one has ever seen the Higgs boson at work. — Kathleen Tibbetts

SMU has an uplink facility on campus for live TV, radio or online interviews. To speak with Dr. Stroynowski or to book him in the SMU studio, call SMU News & Communications at 214-768-7650 or UT Dallas Office of Media Relations at 972-883-4321.

SMU is a private university in Dallas where nearly 11,000 students benefit from the national opportunities and international reach of SMU’s seven degree-granting schools. For more information see www.smu.edu.

Science morphs into science fiction in “Angels & Demons”

“Antimatter” is one of the big stars in the new Ron Howard film “Angels & Demons.” After seeing the movie, people may wonder how much of the science in the film is actually real.

SMU Physics Professor Fredrick Olness says the new action thriller exploits cutting-edge science to create an exciting tale of science fiction mystery and imagination. “Angels & Demons” takes key ideas that are based upon scientific fact, Olness comments, and then exaggerates the details for the purpose of storytelling — and that’s the transformation from “science” to “science fiction.”

In the movie, which opened May 15, members of a centuries-old secret society steal a small container of antimatter from the CERN particle physics laboratory in Europe and threaten to blow up the Vatican. Tom Hanks, as a Harvard professor, tries to stop the society.

“Angels & Demons” is billed as the prequel to the 2006 box-office hit “The Da Vinci Code,” both of which are based on books by best-selling author Dan Brown.

When asked to separate fact from fiction, Olness noted:

Atlas%20event.png• CERN is indeed an international particle physics laboratory near Geneva, Switzerland where hundreds of scientists from around the world study the fundamental laws of nature.

Pictured right: Atlas collision event

• While it is also true that CERN has created antimatter, it would take more than a billion years (with current technology) to make the quantity of antimatter described in the movie. If you collected all the antimatter that CERN has ever created, it would only power an electric light bulb for a few minutes.

• It is true that when antimatter and matter meet, they annihilate into pure energy; however, antimatter is not a source of energy. The production of antimatter is very inefficient, so it takes much more energy to create the antimatter than you get back.

• It is also true that we are able to store antimatter, but scientists don’t actually keep antimatter on the lab shelf. Even small quantities of antimatter are difficult to store. Charged antimatter can be stored in a “magnetic bottle,” but the repulsive force of the antimatter charges greatly limits the quantity. Uncharged (neutral) antimatter cannot be contained by a “magnetic bottle.”

• The CERN laboratory was established in 1954 and has a long history of important scientific discoveries. Two of the discoveries from the CERN lab have been awarded Nobel Prizes, and CERN is the birthplace of the World Wide Web.

Olness spent his 2007-08 sabbatical in residence at CERN as part of a team of SMU scientists working with the Large Hadron Collider, which is featured in the opening scenes from “Angels & Demons.”

The collider, known as the LHC, is the world’s largest and highest-energy particle accelerator. Located near Geneva on the French-Swiss border, the LHC consists of a 17-mile, circular ring of magnets that lies 100 meters beneath the earth’s surface.

“Having spent a year at CERN, I particularly enjoyed the special effects during the LHC scene.” Olness commented. “They paid attention to the details, and even made the background dialogue in the LHC control room credible.”

The purpose of the LHC is to collide two counter-rotating beams of protons traveling at nearly the speed of light. The idea is to smash the protons into smaller particles, and to then gather the mountain of data that results from these “events.” The data will help scientists understand what may have occurred when our Universe came into existence just after the Big Bang. As noted in the movie, LHC scientists are searching for the hypothesized “God particle,” or more scientifically the “Higgs boson.”

As a theoretical physicist, Olness develops the computer models necessary to decipher the results of the LHC experiments. In addition to expanding our knowledge of fundamental science, research at CERN has contributed to important technological innovations such as the World Wide Web, massively parallel (GRID) computing, and improvements in medical imaging.

Tom Hanks toured CERN in February and was visibly impressed with its massive LHC particle accelerator, according to a CERN web site about the science behind the movie.

Hanks commented at CERN: “Magic is not happening here, magic is being explained here.”

CERN quotes Hanks as saying the movie “Angels & Demons” will inspire kids to take a greater interest in science.

National Academy of Sciences: “Peopling of the Americas” researcher awarded highest honor

An SMU archaeologist whose work centers on how people first came to inhabit North America has been elected a member of the National Academy of Sciences (NAS). David Meltzer, chair of SMU’s Department of Anthropology, has been elected a member of the NAS in recognition for his achievements in original scientific research.

david-meltzer

Meltzer’s work looks at the origins, antiquity, and adaptations of the first Americans. Paleoindians colonized the North American continent at the end of the Ice Age. Meltzer focuses on how these hunter-gatherers met the challenges of moving across and adapting to the vast, ecologically diverse landscape of Late Glacial North America during a time of significant climate change.

Membership in the NAS is one of the highest honors given to a scientist or engineer in the United States.

The Henderson-Morrison Professor of Prehistory in Dedman College, Meltzer will be the third SMU professor to be inducted into the NAS. All three have come from the University’s highly regarded anthropology department. Meltzer is also director of QUEST Archaeological Research Program.

Meltzer was elected April 28 along with 71 other scientists, joining more than 2,000 active NAS members. More than 180 living Academy members have won Nobel Prizes. NAS members have included Albert Einstein, Robert Oppenheimer, Thomas Edison, Orville Wright, and Alexander Graham Bell.

“It’s really an honor to be in that wonderful company,” Meltzer said shortly after being notified of his selection by phone. “I am thrilled, excited, shocked, humbled. It’s a great day.” He said he was particularly touched that the NAS members who voted him in then passed a cell phone around to offer their individual congratulations.

“David Meltzer serves as the model of a professor whose research contributes to his discipline and our understanding of civilization, and who uses that knowledge to enliven his classroom,” said SMU President R. Gerald Turner. “His election to the NAS brings much-deserved recognition to Dedman College of Humanities and Sciences and honor to SMU.”

“One of the hallmarks of top universities is the election of their faculty to the prestigious National Academy of Sciences,” said Paul Ludden, university provost and vice president for academic affairs. “SMU is so proud of its top-tier anthropology faculty member, David Meltzer, for his election today.”

Meltzer’s archaeology and history research has been supported by grants from the National Geographic Society, the National Science Foundation, The Potts and Sibley Foundation and the Smithsonian Institution. In 1996, he received a research endowment from Joseph and Ruth Cramer to establish the Quest Archaeological Research Program at SMU, which will support in perpetuity research on the earliest occupants of North America.

His research has appeared in more than 130 publications, and Meltzer has written or edited half a dozen books, including “First People in a New World: Colonizing Ice Age Americans,” recently published by The University of California Press. He received his Ph.D in anthropology/archaeology from the University of Washington in Seattle and joined the faculty at SMU in 1984.

Two emeritus faculty members in SMU’s Anthropology Department are also NAS members: Lewis Binford was elected to the NAS in 2001 and Fred Wendorf was elected in 1987. Only an Academy member may submit formal nominations to the NAS, and supporting nomination materials and candidate lists remain confidential. The evaluation process occurs throughout the year, culminating in a final ballot at the Academy’s annual meeting in April.

The National Academy of Sciences is a private, nonprofit honorific society of distinguished scholars engaged in scientific and engineering research, dedicated to the furthering science and technology and to their use for the general welfare. Established in 1863, the National Academy of Sciences has served to “investigate, examine, experiment, and report upon any subject of science or art” whenever called upon to do so by any department of the government.

HOW I BECAME AN ARCHAEOLOGIST


David Meltzer said that although he had told it many times, this story first appeared in print in “The Dallas Morning News” on Dec. 24, 2001. Photo shows him (below) on his first day in the field in June 1971.

DJM%20at%20TBird%20in%201971.jpg

One June day after school let out (I had just finished 10th grade), my mother asked me what my plans were for the summer. I told her I hoped to slouch on the couch and watch television.

“That,” she announced, “isn’t good enough.” She showed me a piece in The Washington Post (our local newspaper) about excavations beginning in a week’s time in the nearby Shenandoah Valley, at the recently-discovered Thunderbird Paleoindian site.

“Would you like to join the group?”

“Sure,” I said, figuring at that late date the university’s plans must already be set and they couldn’t possibly want to take some snotty high school kid. I went back to watching My Favorite Martian.

Never underestimate your mother.

A day later she’d made fast friends with the administrative assistant at the office, who then talked the project director — Bill Gardner, of Catholic University — into taking me on. He wasn’t so keen on my being there, either! That was over 30 years ago. I went on to excavate for four consecutive seasons at the Thunderbird and nearby Fifty site, and I’ve been doing archaeology ever since.

I’m not sure why that newspaper story caught my mother’s eye, or why she thought her son would enjoy the experience. And I’m certain she didn’t imagine it would set me on a career. But I guess that’s just a mother’s gift, now, isn’t it?

Dig at 16th-century site explores impact of Inca’s empire-building

A 16th century estate in Peru will offer insight into how expanding empires subjugate people and appropriate their resources to promote a cause. Kylie Quave, an SMU graduate student in archaeology, has received a prestigious Fulbright U.S. Student Fellowship to conduct archaeological fieldwork and research in southeastern Peru, the heart of the ancient Inca empire.

The 10-month fellowship begins in August 2009. During that time, Quave intends to excavate residences on the estate of 16th-century emperor Huayna Capac. She hopes to shed light on the Inca elites who lived there and supervised the estate’s daily operations, immigrant laborers and land, which had been appropriated by the nobility.

“The Incas transformed the rural landscape around their capital into immense sources of private wealth,” Quave says. “I hope to contribute to a global understanding of how empires use people and resources to promote their cause and how local communities respond to the imperial campaign.”

During her fellowship, Quave will collaborate with local archaeologists in the field and laboratory, along with local historians in regional and national archives.

With experience as an SMU teaching assistant and as a researcher and docent for the Dallas Museum of Art, she also plans to work with the local community to create educational programming for children and adults.

“We will bring together our diverse perspectives to understand how the Inca developed private investments in the rural heartland using a multiethnic labor force,” she says. “The community will be involved in the preservation of its past.”

Quave, a native of Brooksville, Florida, earned her Bachelor’s degree in art history in 2005 from Emory University. In SMU’s Dedman College, where Quave earned her Master’s degree in 2008, she has taken courses in archaeological method and theory, and previously has done fieldwork in Bolivia and Peru.

“Kylie’s dissertation will move beyond well-known Inca country palaces like Machu Picchu, developing valuable perspectives on how royal families developed and managed private resources that were key to the economic maintenance of the largest native civilization to develop in the Americas,” says Alan Covey, assistant professor of anthropology and Quave’s dissertation adviser. “Her success is the latest for SMU’s doctoral program in anthropology, which recruits talented students and prepares them to make a professional impact early in their careers.”

Graduate student Amanda Aland was awarded a Fulbright in 2008, also to conduct archaeological fieldwork and research in Peru.

Quave is one of 1,450 U.S. citizens selected to study abroad this year through the U.S. State Department’s Fulbright Student Program. More than 40 SMU students have been awarded the fellowship in the last 35 years. — Sarah Hanan
