CNN’s Anderson Cooper 360: Should Children Be Spanked?

Television talk show host Anderson Cooper invited SMU psychologist George W. Holden to weigh in recently on the wisdom and effectiveness of spanking as a way to discipline children.

Holden, an expert in child development, has done research that provides a unique real-time look at spanking in a way that’s never before been studied. In a study of 37 families, mothers voluntarily recorded their evening interactions with their young children over the course of six days, including incidents of corporal punishment.

A professor in the SMU Psychology Department, Holden is a leading advocate for abolishing corporal punishment in schools and homes and led organization of the 2011 Global Summit on Ending Corporal Punishment and Promoting Positive Discipline in Dallas.

For his outstanding dedication and service to the mental health needs of children and adolescents, Holden was honored Sept. 21 with The Lightner Sams Foundation Child Advocate Award presented by Mental Health America of Greater Dallas.

Anderson Cooper 360
Approximately 70-90% of parents use spanking as a disciplinary tactic, says Dr. Holden, Professor of Psychology at Southern Methodist University. This is especially concerning, says Holden, because he’s convinced that any form of hitting a child, whether it be slapping or spanking, is wrong.

“Does this actually make kids more obedient?” asks Anderson.

“It doesn’t,” says Holden, who has studied the effects of spanking for years. “It’s undermining. One-hundred-fifty years ago in this country, husbands were hitting wives when the wives were disobedient,” says Holden. “We now think that’s shocking, and we’d never allow that anymore. I’d like to suggest that us hitting kids is the same thing. We’re assaulting children. They have a right not to be hit.”

WFAA News 8: Perry’s memory gaffe could be linked to studied health issue

“Stress temporarily causes part of the brain called the hippocampus to malfunction,” — Alan Brown

WFAA news reporter Janet St. James interviewed SMU Psychology Professor Alan Brown about what caused Texas Gov. Rick Perry during a recent GOP debate to forget which departments he wanted to abolish.

Brown has studied the phenomenon and has written a book about “Tip of the Tongue” experiences.

Brown’s research primarily involves how people store and retrieve information about the real world, and the manner in which these processes fail us, including the tip of the tongue experience, where one is momentarily stymied in accessing well-stored knowledge.

Another such phenomenon is the false positive recognition experience of déjà vu, where a present experience seems subjectively familiar when one knows that it is objectively new. Brown is currently extending the TOT research to identify the factors underlying repeated TOTs, and whether these change in frequency with age.

EXCERPT:

By Janet St. James
WFAA
Team Perry is in damage control mode, trying to clean up an “Oops” moment at Wednesday night’s GOP debate when Texas Governor Rick Perry couldn’t remember a key point of his presidential campaign.

“The third agency of government I would do away with the education, the uh, the commerce and let’s see. I can’t the third one. I can’t. Oops,” said Perry.

Forgetfulness in geniuses is often considered a sign of brilliance. Einstein was famous for it.

Among the rest of us, senior moments are considered a sign of incompetence, aging, or disease.

Brain researchers said in Perry’s case, it was none of those things.

In fact, there is a name for what happened to Perry.

“The tip of the tongue experience, or state,” said Dr. Alan Brown, memory researcher at SMU. “It’s where you know you have the information, but you just can’t get it out right at the moment.”

Dr. Brown knows all about the phenomenon because he researches the memory and even wrote a book on “The Tip of the Tongue State.”

He said stress temporarily causes part of the brain called the hippocampus to malfunction.

SMU Geothermal Lab project: Vast clean energy source confirmed by Google.org-funded geothermal mapping

Vast coast-to-coast geothermal resource

New research from the SMU Geothermal Laboratory, funded by a grant from Google.org, documents significant geothermal resources across the United States capable of producing more than three million megawatts of green power – 10 times the installed capacity of coal power plants today.

Sophisticated mapping produced from the research, viewable via Google Earth at http://www.google.org/egs/, demonstrates that vast reserves of this green, renewable source of power generated from the Earth’s heat are realistically accessible using current technology.

The results of the new research, from SMU Hamilton Professor of Geophysics David Blackwell and Geothermal Lab Coordinator Maria Richards, confirm and refine locations for resources capable of supporting large-scale commercial geothermal energy production under a wide range of geologic conditions, including significant areas in the eastern two-thirds of the United States.

Resource estimations based on thousands of data sites
The estimated amounts and locations of heat stored in the Earth’s crust included in this study are based on nearly 35,000 data sites – approximately twice the number used for Blackwell and Richards’ 2004 Geothermal Map of North America, leading to improved detail and contouring at a regional level.

Based on the additional data, primarily drawn from oil and gas drilling, larger local variations can be seen in temperatures at depth, highlighting more detail for potential power sites than was previously evident in the eastern portion of the U.S. For example, eastern West Virginia has been identified as part of a larger Appalachian trend of higher heat flow and temperature.

Conventional U.S. geothermal production has been restricted largely to the western third of the country in geographically unique and tectonically active locations.

SMU Researcher to study human-fire-climate interactions

For instance, The Geysers Field north of San Francisco is home to more than a dozen large power plants that have been tapping naturally occurring steam reservoirs to produce electricity for more than 40 years.

Many new regions considered capable of geothermal energy production
However, newer technologies and drilling methods can now be used to develop resources in a wider range of geologic conditions, allowing reliable production of clean energy at temperatures as low as 100˚C (212˚F) – and in regions not previously considered suitable for geothermal energy production. Preliminary data released from the SMU study in October 2010 revealed the existence of a geothermal resource under the state of West Virginia equivalent to the state’s existing (primarily coal-based) power supply.

“Once again, SMU continues its pioneering work in demonstrating the tremendous potential of geothermal resources,” said Karl Gawell, executive director of the Geothermal Energy Association. “Both Google and the SMU researchers are fundamentally changing the way we look at how we can use the heat of the Earth to meet our energy needs, and by doing so are making significant contributions to enhancing our national security and environmental quality.”

“This assessment of geothermal potential will only improve with time,” said Blackwell. “Our study assumes that we tap only a small fraction of the available stored heat in the Earth’s crust, and our capabilities to capture that heat are expected to grow substantially as we improve upon the energy conversion and exploitation factors through technological advances and improved techniques.”

Blackwell is scheduled to release a paper with details of the results of the research to the Geothermal Resources Council in October 2011.

SMU map proposes new international standard for estimating geothermal resource
Blackwell and Richards first produced the 2004 Geothermal Map of North America using oil and gas industry data from the central U.S. Blackwell and the 2004 map played a significant role in a 2006 Future of Geothermal Energy study sponsored by the U.S. Department of Energy that concluded geothermal energy had the potential to supply a substantial portion of the future U.S. electricity needs, likely at competitive prices and with minimal environmental impact. SMU’s 2004 map has been the national standard for evaluating heat flow, temperature and thermal conductivity for potential geothermal energy projects.

In this newest SMU estimate of resource potential, researchers used additional temperature data and in-depth geological analysis for the resulting heat flow maps to create the updated temperature-at-depth maps from 3.5 kilometers to 9.5 kilometers (11,500 to 31,000 feet).

This update revealed that some conditions in the eastern two-thirds of the U.S. are actually hotter than some areas in the western portion of the country, an area long-recognized for heat-producing tectonic activity. In determining the potential for geothermal production, the new SMU study considers the practical considerations of drilling, and limits the analysis to the heat available in the top 6.5 km (21,500 ft.) of crust for predicting megawatts of available power.

This approach incorporates a newly proposed international standard for estimating geothermal resource potential that considers added practical limitations of development, such as the inaccessibility of large urban areas and national parks. Known as the “technical potential” value, it assumes producers tap only 14 percent of the “theoretical potential” of stored geothermal heat in the U.S., using currently available technology.

New technology developments have sparked geothermal development
Three recent technological developments already have sparked geothermal development in areas with little or no tectonic activity or volcanism:

1) Low Temperature Hydrothermal – Energy is produced from areas with naturally occurring high fluid volumes at temperatures ranging from less than boiling to 150°C (300°F). This application is currently producing energy in Alaska, Oregon, Idaho and Utah.

2) Geopressure and Coproduced Fluids Geothermal – Oil and/or natural gas are produced together with electricity generated from hot geothermal fluids drawn from the same well. Systems are installed or being installed in Wyoming, North Dakota, Utah, Louisiana, Mississippi and Texas.

3) Enhanced Geothermal Systems (EGS) – Areas with low fluid content, but high temperatures of more than 150°C (300°F), are “enhanced” with injection of fluid and other reservoir engineering techniques. EGS resources are typically deeper than hydrothermal and represent the largest share of total geothermal resources capable of supporting larger capacity power plants.

Goal is to aid evaluation of regional nonconventional geothermal resources
A key goal in the SMU resource assessment was to aid in evaluating these nonconventional geothermal resources on a regional to sub-regional basis.

Areas of particular geothermal interest include the Appalachian trend (Western Pennsylvania, West Virginia, to northern Louisiana), the aquifer heated area of South Dakota, and the areas of radioactive basement granites beneath sediments such as those found in northern Illinois and northern Louisiana. The Gulf Coast continues to be outlined as a huge resource area and a promising sedimentary basin for development. The Raton Basin in southeastern Colorado possesses extremely high temperatures and is being evaluated by the State of Colorado along with an area energy company.

SMU faculty, students to help UNHCR clean up refugee camp water

The search for solutions to dangerous water quality issues in refugee camps is driving an SMU lab group’s partnership with the United Nations High Commissioner for Refugees. SMU faculty and students will work in the lab and on the ground in Kenya, Uganda, Liberia and Bangladesh.

The group will integrate information from other sources to develop a database that will help UNHCR planners provide safer drinking water in existing and future refugee camps.

Supported by a $270,000 grant from UNHCR and additional SMU funds, faculty member Andrew Quicksall and his graduate students in SMU’s Lyle School of Engineering are collecting water samples in UNHCR camps, bringing samples back to SMU for analysis and also training workers in and around the refugee camps to test water supplies.

SMU Researcher to study human-fire-climate interactions

“They’ve asked us to build out a whole picture, truly worldwide, for what’s in the drinking water in refugee camps,” said Quicksall, the J. Lindsay Embrey Trustee Assistant Professor in the Lyle School of Engineering. “So we’re going to go on-site, collect water, analyze some in the field and bring quite a bit of water back to our SMU laboratories and get a full picture.”

Database to identify contaminants in camps with half a million people
The database developed by Quicksall’s group will identify contaminants in drinking water and allow UNHCR officials to track water quality in the camps over time. Some water quality problems are indigenous to the regions where the camps are situated, some develop over time, and some are the nearly instant consequence of thousands of people collecting in unsuitable locations to escape war and famine faster than sanitary infrastructure can be built.

For example, the agreement with UNHCR commits Quicksall’s team to investigate critical water issues in Dadaab, Kenya ̵ home to the largest refugee complex in the world. Nearly half a million people are concentrated in three camps there, many living in makeshift shelters of twigs, reeds and scraps. Refugees pouring across the border to escape war and famine in Somalia continue to face shortages of food, water, shelter and sanitation hazards there.

“The technical challenges of supporting refugee populations of this size will require that our teams stay engaged with the UNHCR for years to come,” said Geoffrey Orsak, dean of the SMU Lyle School of Engineering. “Fortunately, our new Hunt Institute for Engineering and Humanity makes it possible to lead efforts of this magnitude nearly anywhere on the globe.”

Research to investigate solutions to safe but unpalatable drinking water
Some camps have safe drinking water available, but the taste is so off-putting that residents seek out other sources. In Nakivale, Uganda, for example, the high iron content in well water drives refugees to drink surface water that is frequently contaminated with coliform bacteria. Quicksall’s group also will investigate methods of improving the taste of such safe, but unpalatable, drinking water.

Preliminary research results have revealed problematic concentrations of iodide in drinking water at Dadaab and fluoride in both Southern Uganda and Kakukma, Kenya. Some types of contaminants may not create problems short-term, Quicksall explains, but create severe health issues for people over the long term — particularly children and the elderly. His study group will have the opportunity to both recommend and implement remediation methods for those problem water sources, he said.

“To work with the science in the lab and see it applied internationally — I don’t think there is an opportunity like this anywhere else,” said graduate student Drew Aleto, a member of Quicksall’s study team.

UNHCR and the Hunt Institute for Engineering and Humanity at SMU have signed an agreement establishing a framework for increasing the role of engineering and innovation in support of refugee camp operations. This agreement calls for the engagement of universities, government-run research institutes and corporations to address technical and infrastructure issues faced by UNHCR in helping refugees in relation to water, sanitation, shelter, communications and health care. — Kimberly Cobb

Ancient Etruscan childbirth image unearthed at SMU’s Poggio Colla is likely a first for western art

Image is first of its kind ever found in an Etruscan excavation

An archaeological excavation at Poggio Colla, the site of a 2,700-year-old Etruscan settlement in Italy’s Mugello Valley, has turned up a surprising and unique find: two images of a woman giving birth to a child.

Researchers from the Mugello Valley Archaeological Project, which oversees the Poggio Colla excavation site some 20 miles northeast of Florence, discovered the images on a small fragment from a ceramic vessel that is more than 2,600 years old.

The images show the head and shoulders of a baby emerging from a mother represented with her knees raised and her face shown in profile, one arm raised, and a long ponytail running down her back.

The excavation is a project of Southern Methodist University, Franklin and Marshall College in Lancaster, Penn., and the University of Pennsylvania Museum of Archaeology and Anthropology, in collaboration with The Open University in Milton Keynes, England.

The identification of the scene was made by Phil Perkins, an authority on Etruscan bucchero and professor of archaeology at The Open University.

“We were astounded to see this intimate scene; it must be the earliest representation of childbirth in Western art,” said Perkins. “Etruscan women are usually represented feasting or participating in rituals, or they are goddesses. Now we have to solve the mystery of who she is and who her child is.”

The Etruscans were the first settlers of Italy, long before the Roman Empire. They built the first cities, were a conduit for the introduction of Greek culture to the Romans, and were known for their art, agriculture, fine metalworking and commerce. They occupied Italy for the first millennium B.C., but were conquered by the Romans and eventually became absorbed into their empire.

Image on elite pottery has implications for Poggio Colla sanctuary worship
“The birth scene is extraordinary, but what is also fascinating is what this image might mean on elite pottery at a sanctuary,” said Greg Warden, professor and associate dean for academic affairs at the Meadows School of the Arts at SMU and a director of the Mugello Valley Archaeological Project.

“Might it have some connection to the cult,” Warden said, “to the kind of worship that went on at the hilltop sanctuary of Poggio Colla?”

The fragment was excavated by William Nutt, who is a graduate student in anthropology at the University of Texas at Arlington and who is legally blind. Nutt was participating in the Poggio Colla Field School, which has operated for six weeks every summer since 1995.

Under the supervision of faculty from U.S. institutions and graduate students in classical archaeology and anthropology, the field school has trained approximately 20 students each year, from more than 70 American and European universities, in the theory and practice of archaeological research. Through excavation and scholarship, these students have played an integral role in understanding the Etruscan occupation of the Mugello Valley.

“I was very grateful to be accepted to the summer program at Poggio Colla — it was my first archaeological dig,” said Nutt, who is attending UTA under a National Science Foundation fellowship.

“I found the artifact at the beginning of my second week there. It was quite dirty, and we weren’t sure what it was until it was cleaned at the onsite lab and identified by Perkins,” Nutt said. “It was thrilling to find out that it was so significant. To make a discovery like that, which provides important new information about a culture we know so little about, is exactly what makes archaeology and anthropology so appealing.”

First image of its type from Etruscan sites
The ceramic fragment is less than 1-3/4 x 1-1/4 inches (4 x 3 cm), from a vessel made of bucchero. Bucchero is a fine, black ceramic material, embellished with stamped and incised decorations, used to make eating and drinking vessels for Etruscan elites.

Typically, stamped designs range from abstract geometric motifs to exotic and mythical animals. There are no known Greek or Roman representations of the moment of birth shown as clearly as the Poggio Colla example until more than 500 years later. The fragment dates to about 600 B.C.E. (Before the Common Era).

Because the site at Poggio Colla has produced numerous votive deposits, scholars are certain that for some part of its history it was a sacred spot to a divinity or divinities.

The abundance of weaving tools and a stunning deposit of gold jewelry discovered earlier have already suggested to some scholars that the patron divinity may have been female; the discovery of the childbirth scene, because of its uniqueness, adds another piece of evidence to the theory.

“This is a most exciting discovery,” said Larissa Bonfante, professor emerita of classics at New York University and a world-renowned expert on the ancient Etruscans. “It shows an image of a type so far unknown in Etruscan context and gives us plenty to think about as we try to understand its religious significance.”

A paper about the find will be presented at the annual meeting of the Archaeological Institute of America in Philadelphia in January. The paper, titled “Defining Northern Etruria: Evidence from Poggio Colla (Vicchio di Mugello),” will be presented by Ann Steiner, provost, dean of the faculty and Shirley Watkins Steinman Professor of Classics at Franklin and Marshall College.

Poggio Colla: Highly significant as it spans Etruscan history
Poggio Colla is a highly significant and rare site. One reason is that it spans most of Etruscan history. Archaeological evidence suggests that the site was occupied from around 700 B.C.E. until 187 B.C.E., when it was destroyed by the Romans. Another reason is that it was not buried under later construction. The Etruscans picked beautiful, easily defended hilltops for their settlements. As a result, generation after generation built new cities on top of their sites. That means many have 2000 years of other civilizations on top of Etruscan settlements and cemeteries. Poggio Colla, however, remained in its original condition. Third, Poggio Colla represents an entire settlement, including tombs, a temple, a pottery factory and an artisan community. Excavations of workshops and living quarters are yielding new details about Etruscan life to scholars.

The site centers on the acropolis, a roughly rectangular plateau of one and a half acres at the summit of Poggio Colla. Excavations have found strong evidence that the acropolis was home to a sanctuary and have identified a temple building and an altar at the center of a large courtyard. Numerous offerings have been found buried around the altar, gifts left behind as part of a sacred ritual to a still unidentified deity. These votive donations range from a massive deposit of nearly 500 varied bronze objects, to a spectacular gift of women’s gold jewelry and semi-precious stones. Another votive deposit contains a collection of ritual objects that were laid to rest in a room at the northwest corner of the sanctuary courtyard, possibly by a priest.

Unique religious context allowed first reconstruction of actual rituals
Excavators discovered a large circular pit, at the center of which was placed a sandstone cylinder, possibly the top of a votive column. Carefully situated near the cylinder were two sandstone statue bases, the larger of which includes the inscribed name of the aristocratic donor. Buried alongside these objects were a strand of gold wire, a purposely broken bronze implement, and two bronze bowls that had been used to pour ritual libations, as well as the bones of a piglet, presumably sacrificed as part of a purification ritual. This unique religious context has allowed researchers to reconstruct, for the first time, the actual rituals and actions of the priest/magistrate who presided over the ceremonies.

Although the Etruscan site now called Poggio Colla has been known since the 19th century, it was first excavated from 1968 to 1972 by Francesco Nicosia, the former Superintendent of Archaeology in Tuscany. With Nicosia’s permission and encouragement, SMU professor Greg Warden, a Mugello Valley native, reopened the site in 1995, established the Mugello Valley Archaeological Project and launched the summer Poggio Colla Field School. Today the project continues to proceed with the permission and supervision of the Soprintendenza per i Beni Archeologici per la Toscana and Luca Fedeli, Inspector.

Directors of the project include Warden; Steiner; Michael L. Thomas, senior research associate at the University of Texas at Austin; and Gretchen Meyers, assistant professor of classics at Franklin & Marshall College. They oversee a team of archaeologists, scientists, architects and conservators who are conducting a systematic and multi-disciplined study of Poggio Colla, including stratigraphic excavation, scientific analysis, geophysical mapping and land surveys. — Victoria Winkelman
