Study: Parents of Young Children Lack Time for College Classes

The University of Texas at El Paso’s Alyse C. Hachey, Ph.D., associate professor of early childhood education, co-authored a research paper that for the first time uses data to show that students with preschool-aged children, despite having higher GPAs on average, are at risk because they have significantly lower quantity and quality of time for college than their peers with older or no children.

“Although our findings make intuitive sense and have been assumed for a long time, this is the first study to use empirical methods to prove it by actually gathering and analyzing data,” Hachey said.

“My hope is our research gets policymakers to re-think current support programs and to create new ones for student parents that will really address the issue – time poverty – which is holding them, and potentially the next generation, back.”

The study shows that the main reason for the time differential is the amount of time spent on childcare.

It also shows that a greater availability of convenient and affordable childcare likely would lead to better college outcomes for students with young children.

The researchers conducted their study from 2015 to early 2017, said Hachey, who joined UTEP in fall 2017. They based their findings on institutional data and surveys of students who attended a large, urban U.S. university.

She said research has shown that increased parental education improves the educational outcomes of their children. In fact, parents often are motivated to attend or return to college to provide for their children financially or to set a good example.

The Journal of Higher Education recently published “No Time for College? An Investigation of Time Poverty and Parenthood.” Hachey collaborated on the study with Claire Wladis, Ph.D., professor of mathematics, and Katherine Conway, Ph.D., professor of business management, who both teach at the Borough of Manhattan Community College at the City University of New York.

UTEP Math Professor Named to Land Board

Amy Wagler, Ph.D., associate professor of mathematical sciences, recently was named a member of the Board of Directors for the Frontera Land Alliance.

The nonprofit organization works to protect natural areas, working farms and ranches, water and wildlife. It began in 2005 when community members realized there was an urgent need to preserve some of the important remaining natural and working lands in the greater El Paso and southern New Mexico region.

“I am excited about working with Frontera Land Alliance to promote knowledge and appreciation of our natural environment,” Wagler said. “I am passionate about preservation of natural spaces, particularly in the border region.”

Though her professional expertise is not directly related to ecology and preservation, there is a connection to her research and teaching model.

She is a faculty fellow for UTEP’s Center for Civic Engagement (CCE) where she works to develop a faculty community of practice around community-engaged scholarship, service learning and community-based research.

In the classroom, the statistician has her Applied Regression Analysis students apply their statistics research projects and problem solving work to actual community issues. Wagler says utilizing applications learned inside the classroom helps students experience the impact of using statistics to address real-life situations.

The most recent project her class worked on involved research studies to understand how proximity to green or open space, like Castner Range (, affects property value in El Paso.

UTEP Receives Grant to Increase Diversity in Computer Science

Ann Q. Gates, Ph.D., professor and chair of the Department of Computer Science at The University of Texas at El Paso, has been awarded a grant from the National Science Foundation (NSF) for an initiative titled “Building Upon CAHSI’s Success to Establish a Networked Community for Broadening Participation of Hispanics in Graduate Studies.”

The grant of nearly $300,000 comes to UTEP as one of the first-ever from the NSF INCLUDES (Inclusion across the Nation of Communities of Learners of Underrepresented Discoverers in Engineering and Science) program, a comprehensive initiative to enhance U.S. leadership in science and engineering by broadening participation in the fields of science, technology, engineering and mathematics (STEM).

“This award is strong recognition of the educational quality that UTEP provides to its mostly Hispanic student population, particularly when it comes to future-forward careers in computer systems, human-computer interaction, software engineering and high-performance computing,” said UTEP Vice President of Research Roberto Osegueda, Ph.D.

“It is an honor to be among the first 37 NSF INCLUDES grants awarded,” Gates said. “The shared purpose and vision of our effort is to achieve parity in the number of Hispanics who complete computation-based graduate studies. While there have been strategies for increasing graduate program completion rates for underrepresented minorities, little attention has been paid to the role of Hispanic-Serving Institutions (HSIs) and two-year colleges in reducing attrition. Our collective impact efforts through networked partnerships aim to change this.”

NSF INCLUDES aims to improve access to STEM education and career pathways on a national scale, making them more widely inclusive to underserved populations. Over the next decade, NSF will expand the program, with the goal of developing a science and engineering workforce that better reflects the diversity of U.S. society.

Gates launched the University’s Computing Alliance of Hispanic Serving Institutions, or CAHSI, in 2004 to increase the number of Hispanic students who pursue and complete bachelor’s and advanced degrees in computer and information sciences and engineering. The program will benefit from this award.

“For more than six decades, NSF has funded the development of STEM talent, with the goals of furthering scientific discovery and ensuring the nation’s security, economy and ability to innovate,” said NSF Director France Córdova. “NSF INCLUDES aims to broaden participation in STEM by reaching populations traditionally underserved in science and engineering. I’m gratified to see such a strong start to this program, which we hope will be an enduring investment in our nation’s future in scientific discovery and technological innovation.”

TTUHSC Faculty Develops Policy Recommendations to Support Women in Medicine

Women in medicine often make less money and hold fewer leadership positions than men in medicine.

“The situation is even worse in emergency medicine programs,” says Sue Watts, Ph.D., an associate professor of emergency medicine at Texas Tech University Health Sciences Center El Paso (TTUHSC El Paso). “Just one-third of emergency medicine faculty are women and nearly 75 percent of them have the lowest academic ranks.”

Studies have shown that female faculty members in emergency medicine make 10 to 13 percent less than their male counterparts, and a 2006 report found that only 7.5 percent of emergency medicine departments were chaired by women.

To address these barriers, Watts recently teamed up with a group of women who hold leadership positions in emergency medicine across the country to promote workplace environments that support women. The group created specific guidelines for organizations and institutions to consider implementing in their emergency medicine departments.

Their recommendations, published this month in the journal Academic Emergency Medicine, are as follows:

  • “Employers should implement policies and practices aimed at ensuring unbiased recruitment and hiring and parity in advancement and compensation among employees.
  • Employers should promote and support networking and mentorship opportunities for their women physicians.
  • Employers should strive to implement family-supportive practices that further the professional advancement and retention of employees who have childcare and other dependent care responsibilities.
  • Employers should seek to create a culture in which family-supportive policies are visible and easily accessible, and are used without fear of penalty or stigma. This culture should be evident at the time of recruitment.
  • Employers should adopt policies to support physicians during significant life events (e.g., pregnancy, childbirth, adoption and major medical illness).
  • The needs of pregnant and postpartum women should be supported with flexible scheduling options and adequate lactation facilities.”

The team’s recommendations have been met with considerable endorsement thus far. The policies were quickly adopted by the boards of the Society for Academic Emergency Medicine (SAEM) and the American College of Emergency Physicians (ACEP).

“Even though these guidelines focus on emergency medicine, the best practices could be applied to any other specialty, or adopted as institutional policies,” Watts says.

She hopes the recommendations will impact the medical community and improve the recruitment, retention and advancement of women in medicine throughout the U.S.

UTEP Economics Professor to Officiate 2nd U.S. Olympic Swim Trials

Jim Holcomb, Ph.D., associate professor of economics, will help officiate at the U.S. Olympic swim trials June 25 through July 3, 2016, in Omaha, Nebraska.

Holcomb, chairman of the USA Swimming National Officials Committee, will serve as a deck referee and video replay referee at the meet that determines which swimmers represent the United States at the summer Olympics in August 2016 in Rio de Janeiro, Brazil.

This is the second time the El Paso native has officiated at the nation’s Olympic swim trials. His first experience was 2012 when he served as a deck official.

Holcomb, a three-sport athlete at El Paso’s Eastwood High School, earned his bachelor’s degree in economics from UTEP in 1979, and his master’s and doctoral degrees in economics from Texas Tech and Texas A&M universities, respectively.

He has been a swimming official since 1999 and has officiated at national meets for 14 years.

UTEP Professor Recognized as 2016 State Bar of Texas Inventor of the Year

Marc Cox, Ph.D., associate professor in The University of Texas at El Paso’s Department of Biological Sciences, has been selected as the 2016 Texas Inventor of the Year for his treatments for breast and prostate cancer developed at UTEP.

Cox was chosen as the top inventor in Texas by the Intellectual Property Committee of the State Bar of Texas, who selected the researcher from a highly competitive field of nominees. He is the first awardee from a university and will be recognized at the Annual Meeting of the State Bar of Texas in Fort Worth on June 17, 2016.

Prostate and breast cancer growth is frequently driven in response to the body’s own hormones. As a result, many current therapies include hormone-blocking agents.

However, a significant number of cancers develop the ability to grow even in the absence of hormones because their hormone sensors become stuck in an “on” state that normally only occurs in response to hormones, making them resistant to hormone blocking treatments. Such treatment-resistant cancers account for a significant proportion of prostate cancer deaths and also lead to many breast cancer deaths.

“Dr. Cox’s research has resulted in an entirely new class of drugs that bypasses the hormone sensors all together and instead block internal messages within cancer cells, so the cancer acts as if its hormone sensors are ‘off’ and does not grow. Without a constant message to grow, the cancer may die partially on its own or become much easier to kill with combination treatment,” said Michelle Lecointe, chair of last year’s Inventor of the Year committee.

MarcCox3D“I am both excited and honored to have been named the 2016 Inventor of the Year,” Cox said. “As a scientist, nothing would satisfy me more than to see my work directly contribute to increasing patient quality of life, and my efforts in technology development and commercialization are necessary steps towards that ultimate goal. Recognitions such as this provide strong validation of my technology development efforts, and of the great strides that UTEP has made toward fostering and supporting highly competitive research.”

Cox developed drug candidates that target a critical protein for androgen receptor signaling, which is a process that these cancers are dependent on for growth. Pharmaceutical compounds developed by Cox will help pave the way for the development of similar technologies that have less undesirable side effects than current treatments, thereby improving the quality of life of patients.

Preliminary findings suggest that Cox’s therapeutic strategy will lead to more potent and effective drugs. These drugs will likely demonstrate efficacy toward the treatment of breast and prostate cancers, either alone or in combination with existing therapeutics.

“Dr. Cox is adding new weapons to the clinicians’ arsenal of treatments that will provide greater options for the design of individualized and/or combination therapies, and significantly contribute to the reduction of death from prostate or breast cancer,” said Roberto Osegueda, Ph.D., vice president for research at UTEP.

Cox is currently working with scientists from the National Institutes of Health, Texas Southern University, Clark Atlanta University and the University of Colorado to conduct pre-clinical studies, and is in discussion with collaborators to design the initial clinical testing of the compounds.

Novel technologies and new goods are at the heart of economic progress and the major long-term economic benefits of novel drug technologies include increased longevity of patients, reduced limitations on patient activities including working, and reduced medical expenditures.

Six patents related to Cox’s breast and prostate cancer treatments are currently pending and issued.

“These novel drug technologies and their development toward commercialization attract funding that benefits the University, the University of Texas System and the regional economy through increased research expenditures and the creation of jobs,” said Melissa Silverstein, director of UTEP’s Office of Technology Commercialization.

To date, these technologies have attracted close to $2.3 million in research funding and created at least five new jobs within the academic research sector in Cox’s lab at UTEP.

Provost Names 2016-17 Faculty Fellows for Civic Engagement

The Office of the Provost has named Mark Lusk, Ed.D., professor of social work, and Amy Wagler, Ph.D., associate professor of mathematical sciences, as The University of Texas at El Paso’s 2016-17 Faculty Fellows for the Center for Civic Engagement (CCE).

Lusk and Wagler will collaborate with the CCE in continuing to develop a faculty community of practice around community-engaged scholarship, service learning and community-based research.

They bring to their positions broad knowledge and experience in community-engaged scholarship and have already demonstrated leadership in expanding the awareness, knowledge and engaged practices of their staff and faculty colleagues on campus.

The Provost’s Administrative Faculty Fellow positions are intended to provide faculty members with leadership and administrative experience, while offering faculty perspective, guidance and vision to the administrative offices they serve.

Faculty fellows work closely with program directors on projects that help those units address UTEP’s mission and goals.

The mission of UTEP’s Center for Civic Engagement is to engage faculty and students in the community through community-based teaching and learning in order to enhance student learning, promote civic engagement and actively improve the El Paso-Juárez region.

UTEP Professor Earns Prestigious Award at Bilingual Conference

The Government of Mexico recognized UTEP’s Josefina V. “Josie” Tinajero, Ph.D., with its Regional Ohtli Award on March 4, 2016, during the 45th annual National Association for Bilingual Education conference in Chicago, Illinois.

The Ohtli, which means “road” in the Aztec Nahuatl language, is one of the most prestigious honors awarded to leaders in their professions outside of Mexico who have distinguished themselves professionally to secure the well-being of Mexicans abroad and to enhance the quality of life of migrant populations. The award is given annually. Past recipients have been artists, actors, politicians and community leaders.

“I am honored beyond words,” Tinajero said. She is a professor of bilingual education and special adviser to The University of Texas at El Paso’s vice president for research. “I am extremely excited and feel so blessed. This is a very special honor since it is being awarded by the government of my native country.”

Tinajero, who learned English as an elementary school student in El Paso, said she decided early on that she would pursue a teaching career to help others, especially children, who needed help adapting to a new language and culture. She did not want them to experience what she experienced in school.

During her 40-year career, she has become an acknowledged international expert in the field of bilingual education. She has dedicated her professional life to shaping public policy in the U.S. to help English as a Second Language children and their families.

Miguel Basáñez Ebergenyi, Ph.D., Mexican ambassador to the United States, said in a Feb. 9, 2016, letter to Tinajero that the decision to honor her was based on her extensive work to promote gender equity, cultural diversity and access to higher education in the Hispanic community.

“Education and opportunities have definitely been improved not only in Texas but in the United States, thanks to the scholarship and funding programs where you have participated as well as in the projects oriented to improve teaching training,” he wrote. “As is well known, education is one of the most important resources for any nation and also, one of the most valuable tools required to integrate and empower migrant communities.”

Howard Daudistel, Ph.D., vice president for academic affairs and interim provost, said the University was delighted with Tinajero’s latest acknowledgement because it highlighted her contributions to bilingual education and UTEP’s role in broadening the educational pathways for people of this region.

“This recognition of Dr. Tinajero reflects positively on the University’s continuing desire to serve students of all backgrounds who come to us hoping to fulfill their dreams and aspirations.​”

Tinajero said she was especially grateful to her deceased parents – Reveriano Alfonso Villamil, a Mexican national, and Maria Rosa Villamil, a Mexican-American – for the tremendous respect and admiration they shared with her for the Mexican culture, history and native language. They played a significant role in encouraging their nine children to go to college.

“I decided to do the things I did in my life because I wanted to make a difference in the lives of Latinos at a national level,” she said. “(My parents) would be very proud of me because I’m helping others reach their potential.”

The award, established in 1996, includes a gold medal, a rosette and a certificate.

Plant Extract Shows Promise in Treating Pancreatic Cancer

A natural extract derived from India’s neem tree could potentially be used to treat pancreatic cancer, according to a new study in the journal Scientific Reports.

Biomedical scientists at Texas Tech University Health Sciences Center El Paso (TTUHSC El Paso) tested nimbolide, a compound found in neem leaves, against pancreatic cancer in cell lines and

mice. The results revealed that nimbolide can stop pancreatic cancer’s growth and metastasis without harming normal, healthy cells.

“The promise nimbolide has shown is amazing, and the specificity of the treatment towards cancer cells over normal cells is very intriguing,” says Rajkumar Lakshmanaswamy, Ph.D., an associate professor in TTUHSC El Paso’s Center of Emphasis in Cancer.

Pancreatic cancer has the highest mortality rate of all cancers with 94 percent of patients dying within five years of diagnosis. The cancer grows quickly and there are currently no effective treatments available, underscoring the importance of finding new therapies.

In the study, Lakshmanaswamy and his lab observed that nimbolide was able to reduce the migration and invasion capabilities of pancreatic cancer cells by 70 percent; meaning the cancerous cells did not become aggressive and spread. And that’s promising, the researchers say. In humans, this migration and invasion (metastasis) of pancreatic cancer to other regions of the body is the chief cause of mortality.

Nimbolide treatments also induced cancer cell death, causing the size and number of pancreatic cancer cell colonies to drop by 80 percent. “Nimbolide seems to attack pancreatic cancer from all angles,” Lakshmanaswamy says.

The TTUHSC El Paso researchers stress that one of the most important findings is that nimbolide did not harm healthy cells in both the in vitro and in vivo experiments.

AutophagyLead author and postdoctoral researcher Ramadevi Subramani, Ph.D., explains, “Many people in India actually eat neem and it doesn’t have harmful side effects, which suggests that using nimbolide for pancreatic cancer will not cause adverse effects like chemotherapy and radiation typically do.”

While the results are promising, Lakshmanaswamy says there’s still a long way to go before nimbolide can be used to treat pancreatic cancer in humans.

The TTUHSC El Paso team plans to continue researching the anticancer mechanisms behind the plant extract. They’ll also study various ways to administer nimbolide to maintain its potency against pancreatic cancer.

Additional TTUHSC El Paso collaborators who participated in the study were postdoctoral researchers Arunkumar Arumugam, Ph.D., Sushmita Nandy, Ph.D., and graduate students Fernando Camacho, Elizabeth Gonzalez, and Joshua Medel.

UTEP Professor shows hearing aids improve memory, speech

A recent study by Jamie Desjardins, Ph.D., an assistant professor in the Speech-Language Pathology Program at The University of Texas at El Paso, found that hearing aids improve brain function in persons with hearing loss.

Hearing loss, if left untreated, can lead to serious emotional and social consequences, reduced job performance and diminished quality of life. Untreated hearing loss also can interfere with cognitive abilities because so much effort is put toward understanding speech.

“If you have some hearing impairment and you’re not using hearing aids, maybe you can figure out what the person has said, but that comes with a cost,” Desjardins explained. “You may actually be using the majority of your cognitive resources – your brain power – in order to figure out that message.”

As people age, basic cognitive skills – working memory, the ability to pay attention to a speaker in a noisy environment, or the ability to process information quickly – begin to decline.

Desjardins studied a group of individuals in their 50s and 60s with bilateral sensorineural hearing loss who had previously never used hearing aids.

They took cognitive tests to measure their working memory, selective attention and processing speed abilities prior to and after using the hearing aids.

After two weeks of hearing aid use, tests revealed an increase in percent scores for recalling words in working memory and selective attention tests, and the processing speed at which participants selected the correct response was faster.

By the end of the study, participants had exhibited significant improvement in their cognitive function.

“Most people will experience hearing loss in their lifetime,” said Desjardins, who joined UTEP in 2013. “Think about somebody who is still working and they’re not wearing hearing aids and they are spending so much of their brainpower just trying to focus on listening. They may not be able to perform their job as well. Or if they can, they’re exhausted because they are working so much harder. They are more tired at the end of the day and it’s a lot more taxing. It affects their quality of life.”

Hearing loss affects more than 9 million Americans over the age of 65 and 10 million Americans ages 45 to 64, but only about 20 percent of people who actually need hearing aids wear them, Desjardins said.

Desjardins’ new study focuses on the use of hearing aids by Hispanics. Research shows that only five percent of Mexican-Americans wear hearing aids. She has developed a survey to investigate their attitudes toward hearing loss. The survey will be conducted at health fairs in the community, including the Mexican Consulate in El Paso, Texas.

Desjardins also will begin work on another study that will look at older bilingual people and their ability to understand speech.

Desjardins earned both a master’s degree and a Ph.D. in audiology from Syracuse University in Syracuse, New York.

UTEP Computer Science Department develops award-winning interactive Agent System

University of Texas at El Paso Professor of Computer Science David Novick, Ph.D., and his students have developed a system for virtual agents and an immersive interactive application titled “Survival on Jungle Island.”

The UTEP AGENT system was created to study understanding between embodied conversational agents (ECAs) and humans, with emphasis on the effects of paralinguistic behaviors on engagement and rapport. Paralinguistics includes behaviors such as gesture, intonation and rhythm in speech, gaze and turn taking. The team’s research includes work on personality traits of humans and agents.

In “Survival on Jungle Island,” the ECA and a human interact, using speech and gesture, in a 40-60 minute adventure composed of 23 scenes. A study conducted with the adventure showed that rapport increases when the ECA asks the human to perform task-related gestures and then perceives a human performing these gestures.

In the jungle adventure, the system simulates a survival scenario in which the player interacts with the ECA, Adriana. In order to survive, both human and ECA must collaborate, cooperate and build a relationship.

The game begins with a cinematic sequence of a stormy shipwreck, providing background information as to how the person ended up in the survival situation. This scene is followed by another two scenes, which serve as an inconspicuous tutorial to avoid breaking the impression of an immersive reality.

The first scene contains personal questions that let the player and the ECA get to know each other, giving the impression that Adriana is processing what she hears. The second scene moves the story forward by providing an explanation as to how the ECA Adriana has survived in the jungle so far, and shows that she reacts to the player’s responses.

At the end of the scene, the story continues to develop depending on the player’s choice of what to do next.

Novick created the system with the help of his Advanced aGent ENgagement Team (AGENT), comprising postdoctoral fellow Ivan Gris; UTEP undergraduate and graduate students Adriana Camacho, Alex Rayon, Joel Quintana, Anuar Jauregui, Timothy Gonzales, Alfonso Peralta, Victoria Bravo, Jacqueline Brixey, Yahaira Reyes and Paola Gallardo; French Air Force Academy cadets Guillaume Adoneth and David Manuel; and El Paso high school students Brynne Blaugrund and Nick Farber.

To enable the interaction between humans and ECAs, the team combined the use of Unity 4, an animation software; a Microsoft Kinect motion sensing device; and the Windows Speech SDK software. The team also built “middleware,” which enabled more rapid development of applications including the jungle adventure.

The UTEP AGENT system recently received the award for Outstanding Demonstration at the 17th ACM International Conference on Multimodal Interaction held in November in Seattle, Washington.

“UTEP’s virtual-agent team now ranks among the best in the world,” Novick said. “We are both building exciting new virtual-agent technology and learning how to make agents more adaptable to humans.”
