Research: SMU study finds helicopter parenting harms boys and girls in different ways

Students Studying in Fondren Library CenterSMU researchers have found surprising gender differences in how college students react to misguided parenting. Their findings on the impact of helicopter parenting and fostering independence have been reported in a new article, “Helicopter Parenting, Autonomy Support, and College Students’ Mental Health and Well-being: The Moderating Role of Sex and Ethnicity,” in the Journal of Child and Family Studies.

Measuring both helicopter parenting as well as autonomy support — fostering independence — was important for the researchers to study, said family dynamics expert Chrystyna Kouros, SMU assistant professor of psychology and an author on the study.

“Just because mom and dad aren’t helicopter parents doesn’t necessarily mean they are supporting their young adult in making his or her own choices,” Kouros said. “The parent may be uninvolved, so we also wanted to know if parents are actually encouraging their student to be independent and make their own choices.”

The researchers found that young women are negatively affected by helicopter parenting, while young men suffer when parents don’t encourage independence.

“The sex difference was surprising,” said Kouros, an expert in adolescent depression. “In Western culture in particular, boys are socialized more to be independent, assertive and take charge, while girls are more socialized toward relationships, caring for others, and being expressive and compliant. Our findings showed that a lack of autonomy support — failure to encourage independence — was more problematic for males, but didn’t affect the well-being of females. Conversely, helicopter parenting — parents who are overinvolved — proved problematic for girls, but not boys.”

The study is unique in measuring the well-being of college students, said Kouros, director of SMU’s Family Health and Development Lab. The tendency in research on parenting has been to focus on the mental health of younger children.

“When researchers do focus on college students they tend to ask about academic performance, and whether students are engaged in school. But there haven’t been as many studies that look at mental health or well-being in relation to helicopter parenting,” she said.

Unlike children subjected to psychological control, in which parents try to instill guilt in their child, children of helicopter parents report a very close bond with their parents. Helicopter parents “hover” out of concern for their child, not from malicious intent, she said.

What helicopter parents don’t realize is that despite their good intentions to help their child, it actually does harm, said Naomi Ekas, a co-author on the study and assistant professor of psychology at Texas Christian University in Fort Worth.

“They’re not allowing their child to become independent or learn problem-solving on their own, nor to test out and develop effective coping strategies,” Ekas said.

Young men that reported more autonomy support, measured stronger well-being in the form of less social anxiety and fewer depressive symptoms.

For young women, helicopter parenting predicted lower psychological well-being. They were less optimistic, felt less satisfaction with accomplishments, and were not looking forward to things with enjoyment, nor feeling hopeful. In contrast, lacking autonomy support wasn’t related to negative outcomes in females.

“The take-away is we have to adjust our parenting as our kids get older,” said Kouros. “Being involved with our child is really important. But we have to adapt how we are involved as they are growing up, particularly going off to college.”

Other co-authors on the study are Romilyn Kiriaki and Megan Sunderland, SMU Department of Psychology, and Megan M. Pruitt, Texas Christian University. The study was funded by the Hogg Foundation for Mental Health at UT-Austin.

Research: Hunting down cancer-causing viruses that hide from the immune system

Robert L. Harrod, Biology Lab ResearchSMU virologist and cancer researcher Robert L. Harrod has been awarded a $436,500 grant from the National Cancer Institute to further his lab’s research into how certain viruses cause cancers in humans.

Under two previous NCI grants, Harrod’s lab discovered that the human T-cell leukemia virus type-1, HTLV-1, and high-risk subtype human papillomaviruses, HPVs, share a common mechanism that plays a key role in allowing cancers to develop. Now the lab will search for the biological mechanism — a molecular target — to intervene to block establishment and progression of virus-induced cancers. The hope is to ultimately develop a chemotherapy drug to block the growth of those tumor cells in patients.

“The general theme of our lab is understanding the key molecular events involved in how the viruses allow cancer to develop,” said Harrod, an associate professor in SMU’s Department of Biological Sciences whose research focuses on understanding the molecular basis of viral initiation of cancer formation.

While HTLV-1 and HPV are unrelated transforming viruses and lead to very different types of cancers, they’ve evolved a similar mechanism to cooperate with genes that cause cancer in different cell types. The lab discovered that the two viruses tap a common protein that cooperates with cellular genes to help the viruses hide from the immune system.

That common protein, the p30 protein of HTLV-1, binds to a different protein in the cell, p53, which normally has the job of suppressing cancerous growth or tumor development. Instead, however, p30 manages to subvert p53’s tumor suppressor functions, which in turn activates pro-survival pathways for the virus.

From there, the virus can hide inside the infected cell for two to three decades while evading host immune-surveillance pathways. As the cell divides, the virus divides and replicates. Then ultimately the deregulation of gene expression by viral encoded products causes cancer to develop.

“They are essentially using a similar mechanism, p30, to deregulate those pathways from their normal tumor-suppressing function,” Harrod said.

Research: New SMU study connects running motion to ground force

SMU researchers have developed a concise new explanation for the basic mechanics involved in human running. Their research has immediate application for running performance, injury prevention, rehab and the individualized design of running shoes, orthotics and prostheses.

The work integrates classic physics and human anatomy to link the motion of individual runners to their patterns of force application on the ground – during jogging, sprinting and at all speeds in between.

The approach could enable the use of individualized gait patterns to optimize the design of shoes, orthoses and prostheses according to biomechanics experts Kenneth Clark, Laurence Ryan and Peter Weyand, who authored the new study.

The ground force-time patterns determine the body’s motion coming out of each step and therefore directly determine running performance. The impact portion of the pattern is also believed to be a critical factor for running injuries.

“The human body is mechanically complex, but our new study indicates that the pattern of force on the ground can be accurately understood from the motion of just two body parts,” said Clark, first author on the study and currently an assistant professor in the Department of Kinesiology at West Chester University in West Chester, Pennsylvania.

“The foot and the lower leg stop abruptly upon impact, and the rest of the body above the knee moves in a characteristic way,” Clark said. “This new simplified approach makes it possible to predict the entire pattern of force on the ground — from impact to toe-off — with very basic motion data.”

Provost creates SMU faculty Task Force on Scholarly Research and Creative Impact

SMU Provost and Vice President for Academic Affairs Steven C. Currall has appointed 17 University faculty members to serve on the Task Force on Scholarly Research and Creative Impact. The new task force, which began meeting in October, will examine and recommend ways for SMU to strengthen its scholarly research and creative activities to bolster the University’s position as the leading global research university in North Texas.

“SMU is in a unique position because of our geography, resources and faculty expertise to make significant strides in scholarly research,” Currall said. “For example, our high-performance computing capability, a university-wide focus on interdisciplinarity, and arts and cybersecurity research, along with our advantageous location near the heart of Dallas, have the University poised to expand its research footprint and become an even stronger catalyst for regional economic prosperity.”

Currall said the task force will provide “vital faculty-led guidance on how to strengthen our scholarly research and creative activities,” adding that “faculty leadership in this endeavor is crucial.”

Meadows Museum curator solves mystery of the Spanish masterworks

[youtube]https://www.youtube.com/watch?v=UK7T2oJg5UM[/youtube]SMU’s Meadows Museum has concluded a lengthy investigation into the true identity and postwar provenance of two of the most famous paintings in its collection – masterworks that had been seized by the Nazis during World War II.

With the help of a series of serendipitous discoveries and six years of relentless detective work by curator Nicole Atzbach, the Museum now has definitive evidence to prove that Saint Justa and Saint Rufina by Spanish master Bartolomé Esteban Murillo had in fact been lawfully restituted to the Rothschild family following the war, long before their 1972 sale to the Museum.
