UTSA researcher studies key predictors for college retention
2021-03-18
(Press-News.org) (MARCH 17, 2021) - The current outbreak of COVID-19 has raised many questions about the value of consideration of standardized testing through the admissions process. One of the many Coronavirus cancellations included a growing number of universities to waive SAT and ACT scores as an admissions requirement for 2022 applicants.
With schools shifting their policy to making standardized "test-optional" and possibly permanently phasing out testing scores in the future as some college experts argue that standardized tests create barriers to students which could reduce their likelihood of acceptance.
A new study led by senior research scientist Paul Westrick from the College Board (ACT, Inc.), along with UTSA professor of management, Huy Le, Steve Robbins from the Educational Testing Service, Justin Radunzel ACT, Inc, and Frank Schmidt, professor emeritus of management and entrepreneurship at the University of Iowa shows that the most effective way to predict students' academic success and retention in a student first year of college relies heavily on test scores and grades combined together.
Based on a national representative sample of 189,612 students at 50 institutions, both ACT scores and high school grade point average are correlated to a first-year students' academic performance, the researchers made important contributions on academic persistence.
The study aims to examine the strength of correlation between ACT Composite scores, school grades, and socioeconomic status within the second- and third-year academic performance.
"We believe this research provides important evidence supporting the usefulness of high school GPA and standardized tests as predictors of student successes in colleges and refuting the misconception that the tests are just a proxy for students' socio-economic status," said Le.
The researchers provided valuable insight to determine the factors that best predict the effectiveness and reliability of continuing to use the practice of standardized tests as a measure of student success and whether or not they will persist in college.
"We are hopeful the findings of the study will help colleges in determining factors to be included for making admission decisions," Le added.
The researchers concluded that grades do not only measure academic characteristics but nonacademic characteristics as well. The findings demonstrate that test scores measure cognitive characteristics, while grades measure a combination of characteristics. Including attendance, participation and more.
The research has yielded many studies that have demonstrated the usefulness and validity of the standardized testing for the admission process.

Mass movements such as landslides and hill-slope debris flows cause billions of euros in economic damage around the world every year. Between 20 and 80 million euros are spent annually from the disaster fund to repair disaster damage in Austria, 15 to 50 percent of which is attributable to mud flows and landslides. Now, a team of geologists from Graz University of Technology (TU Graz), in cooperation with the Burgenland state road administration, identified for the first time the chemical influencing factors and triggers for recurrent mass movements in fine-grained sediments. From results published in the journal Science of the Total Environment, preventive measures and strategies ...

Lenexa, Kan. -- The Infusion Nurses Society has expanded its guidance on the use of needleless connectors to include anti-reflux technology in its recently published 2021 Infusion Therapy Standards of Practice, according to Nexus Medical, makers of the Nexus TKO®-6P Anti-Reflux connector.
As INS' most recognized publication, the updated Standards outline specific categories of needleless connector technology based on the device's internal mechanism for fluid displacement -- negative displacement, positive displacement, neutral and anti-reflux. Of all the categories, the authors note that anti-reflux needleless connectors cause the least amount of blood reflux, which can ...

A groundbreaking new study led by University of Minnesota Twin Cities researchers from both the College of Science and Engineering and the Medical School shows for the first time that lab-created heart valves implanted in young lambs for a year were capable of growth within the recipient. The valves also showed reduced calcification and improved blood flow function compared to animal-derived valves currently used when tested in the same growing lamb model.
If confirmed in humans, these new heart valves could prevent the need for repeated valve replacement surgeries in thousands of children born each year with congenital heart defects. The valves can also be stored for at least six months, which means they could provide surgeons with an "off the shelf" option for treatment.
The ...

A long noncoding RNA whose function was previously unknown turns out to play a vital role in mobilizing the immune response following a bone marrow transplant or solid organ transplantation.
This RNA molecule, cataloged in scientific databases simply as Linc00402, helps activate immune defenders known as T cells in response to the presence of foreign human cells, according to a new study by researchers at the University of Michigan Rogel Cancer Center and Michigan Medicine.
The investigation, which included samples from more than 50 patients who underwent a bone marrow or heart transplant, suggests inhibiting ...

MEMPHIS, Tenn. - Non-Hispanic black patients with Type 1 diabetes and COVID-19 were almost four times as likely to present to the hospital with diabetic ketoacidosis (DKA) compared to non-Hispanic whites, according to an article published in The Journal of Clinical Endocrinology & Metabolism by Le Bonheur Pediatric Endocrinologist Kathryn Sumpter, MD.
The study examined 180 patients with Type 1 diabetes and laboratory-confirmed COVID-19 from 52 clinical sites, including Le Bonheur Children's. The objective of the study was to evaluate instances of DKA, a serious complication of Type 1 diabetes, in patients with Type 1 diabetes and COVID-19 and determine if minorities had increased ...

ITHACA, N.Y. - If you want to build a fully functional nanosized robot, you need to incorporate a host of capabilities, from complicated electronic circuits and photovoltaics to sensors and antennas.
But just as importantly, if you want your robot to move, you need it to be able to bend.
Cornell researchers have created micron-sized shape memory actuators that enable atomically thin two-dimensional materials to fold themselves into 3D configurations. All they require is a quick jolt of voltage. And once the material is bent, it holds its shape - even after the voltage is removed.
As a demonstration, the team created what ...

The coronavirus' structure is an all-too-familiar image, with its densely packed surface receptors resembling a thorny crown. These spike-like proteins latch onto healthy cells and trigger the invasion of viral RNA. While the virus' geometry and infection strategy is generally understood, little is known about its physical integrity.
A new study by researchers in MIT's Department of Mechanical Engineering suggests that coronaviruses may be vulnerable to ultrasound vibrations, within the frequencies used in medical diagnostic imaging.
Through computer simulations, the team has modeled the virus' mechanical response to vibrations across a range of ultrasound ...

A new study has found that about 35% of Americans with a cancer history had an elevated risk of cardiovascular disease in the next decade, compared with about 23% of those who didn't have cancer.
Based on a risk calculator that estimates a person's 10-year chances of developing heart disease or stroke, researchers from The Ohio State University found that the average estimated 10-year risk for a cancer survivor was about 8%, compared to 5% for those who didn't have a history of cancer.
The new study appears in the journal PLOS ONE.
"We know that obesity, cancer and cardiovascular disease share some common risk factors, and in addition to those shared risk factors, cancer patients also receive treatments including radiation and chemotherapy that can affect their cardiovascular ...

Many people have never heard of Brucellosis, but farmers and ranchers in the United States forced to cull animals that test positive for the disease and people infected by the animal-transmitted Brucella abortus (B. abortus) pathogen that suffer chronic, Malaria-type symptoms, certainly have.
Brucellosis is an agricultural and human health concern on a global scale. It was introduced over 100 years ago to Bison and elk in Yellowstone National Park by cattle and has been circulating among the wild herds ever since, leading to periodic outbreaks and reinfection. There is no vaccine for humans, and experimental studies ...

GRAND RAPIDS, Mich. (March 16, 2021) -- Older age at the time of conception and alcohol consumption during pregnancy have long been known to impact fetal development.
Now, a new report published in Proceedings of the National Academy of Sciences suggests older age and alcohol consumption in the year leading up to conception also may have an impact by epigenetically altering a specific gene during development of human eggs, or oocytes.
Although the study did not determine the ultimate physical effects of this change, it provides important insights into the intricate relationship between environmental exposures, genetic regulation and human development.
"While the outcome of the change isn't clear, our findings give us a valuable look into ...
