Do you remember the feeling you had the first time sitting at the wheel of a car? Were you overcome by the feeling of excitement, anticipation, fear, or perhaps a combination of them all? For many, obtaining a driver’s license is a rite of passage; a symbol that you are equipped with both the knowledge and skill of how to safely operate a motor vehicle. This achievement, however, would not have been made possible without the sacrifice of devoting hours to driver’s education and training under a supervisor.

Forging new paths

By the same token, college students who have dedicated years of study in various academic fields may also be ambivalent about conducting research. They will be in dire need of an experienced researcher’s guidance as they navigate down the unfamiliar road of academic research. It is their responsibility to help shape the student’s research interests and forge new paths.

By fostering student-led research, faculty sponsors can assist students by aligning their educational experiences with their career goals. This positions them for compelling careers in academic research.

Student at the wheel

Before a student can be placed in the driver’s seat of their own research protocol, they must be fully equipped with the right tools. If not, they will begin this journey without clear direction. Such was the case of several students at an unnamed university who conducted more than minimal risk studies without IRB approval.

The students started the protocol but were advised by their faculty sponsor that IRB approval wasn’t necessary before conducting research. One of the students rode in ambulances collecting data. They published their findings and even graduated before this was brought to the attention of the university’s Office of Compliance. This is a clear case of noncompliance and the severity of this issue is similar to driving a car without a license.

The Institutional Review Board (IRB) is the governing entity for human subject research. Their role isn’t primarily a research review process. It ensures that human subjects are treated ethically and that their rights are protected. This brought up issues of consent, confidentiality, and potential risk to human subjects and was an example of significant non-compliance.

Federal regulations and university policy mandate IRB approval for research involving human subjects. The requisite applies to faculty, staff and students. The availability of options may create more questions than answers when submitting their first student-led research protocol.

Mapping it out

The University of Houston has taken steps to manage research compliance and optimize student success. It established an Institutional Review Board that reviews only student-led protocols. It’s unique in that very few institutions have this sort of program available. In the two years since its inception, the program has become a transformative resource for both students and their faculty advisors.

Faculty and student protocols are typically grouped together. However, the UH Student IRB Program gives them a single point of contact for IRB-related concerns and individualized support.

The UH Office of Research Integrity and Oversight (RIO) has established an infrastructure to support student-led research through their pre-IRB review process. Students are encouraged to drop by to seek advice or brainstorm with a coordinator. Services, training and educational materials, such as the Faculty Sponsor Manual, are also available to support faculty sponsors.

The submission process can be pretty daunting. Kirstin Holzschuh, executive director of RIO, mentioned that students are unfamilar with the IRB requirements and process. As a result, their protocols would often be sent back for significant revisions. The pre-review system helps eliminate the possibility of their protocols getting stuck in the review process.

Representatives from this office regularly interface with the UH research community. They travel to various colleges and departments across campus and guest lecture on the IRB submission process. They also talk about the ethics of conducting research with human subjects.

Students and faculty sponsors work in tandem to design and implement a research or scholarly project. Therefore, it’s imperative to cultivate an environment where student researchers feel informed and supported by their advisors and the UH community.

University of Houston: Navigating non-compliance and human error in research

houston voices

To comply is to obey, or conform to instruction or official requirements. In a perfect world, research non-compliance wouldn’t occur and following the rules would be a behavioral norm. But the reality is, to err is human.

To err is human

Often times the judgement of our own, and others, poor decision-making is rooted in the innate tendency to view things in black or white – categorizing behaviors as either right or wrong, good or bad, thus deeming them as either ethical or unethical.

But this way of thinking often conflicts with the gray world in which we exist. So what happens when research decisions land somewhere in the moral gray area?

Before answering, here are two situations to consider that involve the over-enrollment of research participants:

Case 1:
The IRB has approved a survey for 40 subjects. The PI realizes after the survey has been open for several weeks that she forgot to set a participant limit within the survey program and 60 subjects have completed the survey.

Case 2:

A study involving a new drug to control diabetes symptoms is approved to enroll 30 participants. The study doctor thinks the drug may be beneficial, so she continues enrolling, for a total of 80 subjects.

The devil is in the details

Why is over-enrollment of subjects considered non-compliance?

Many institutions have agreed, within their assurance to the U.S. Department of Health and Human Services (HHS), to apply the Common Rule to all human subjects research, whether the research is funded or not.

The Common Rule regulations found at 45 CFR 46.109(a) and 45 CFR 46.111 (1) state that the IRB shall review and have authority to approve, require modifications in (to secure approval), or disapprove all research activities. This includes the maximum number of research .

And what must the IRB review?

Under the above regulatory requirements, the IRB must evaluate all instances of non-compliance.

In these cases of over-enrollment, the IRB must review the number of subjects over-enrolled and assess any potential effects on additional subjects and/or the research, as well as determine if the noncompliant data may be used for research purposes.

What UH IRB says about Case 1:

While over-enrollment in a survey seems low-risk, depending on the content of the survey questions, the IRB could determine the issue to be more serious, such as for a study collecting data related to illegal substance use or questions about traumatic events (legal or psychological harm). The IRB must ensure that risks to subjects are minimized; only the number of subjects needed to statistically justify the research are approved. Depending on the number of subjects over-enrolled and the time period over which they participated, the non-compliance could also be considered continuing.

What UH IRB says about Case 2:

Investigational drug studies often pose more than minimal risk of harm to subjects. In these studies, it is even more critical to ensure that additional subjects are not exposed to potential harms without scientific justification

In a drug study, the PI may not continue a study based on opinion; the reason a physician is blinded to treatment assignment in many drug studies is to avoid potential bias.

Finding non-compliance: What can you do?

If the number of subjects enrolled exceeds the number approved by the IRB, a finding of non-compliance is justified. The IRB will review the numbers, the Principal Investigator’s reasons for over-enrollment and assess what procedures were conducted in these subjects. Often over-enrollment is inadvertent, however the committee also has the ultimate authority to determine whether the data may be used for research purposes.

Corrective actions, such as continuing education of the PI and/or study team to ensure this issue does not occur again in the future, are often required. In the most serious cases, the IRB may suspend or terminate approval.

If the non-compliance rises to the level of being serious (harms or has the potential to harm subjects or others) and/or continuing in nature, it must be reported to federal oversight agencies such as the Health and Human Services Office for Human Research Protections (OHRP) and the FDA. These agencies ensure that the institution is monitoring for these activities and puts appropriate fixes in place.

The importance of intetrity

Non-compliant research can be due to inadvertent errors or deliberate acts of noncompliance. The results could be the same. Human subjects could be harmed. Funding and reputation at an institution conducting research could be negatively affected. In times of reduced federal funding for basic research, there are direct financial costs to the agencies when funds and resources are misused.

The responsibility of ensuring that research protocols are adhered to rests upon the shoulders of the researchers involved.

If you were a member on the IRB, what would you consider to be appropriate consequences for the PI in these situations?

It’s important to note that non-compliance, whether it’s a “little white lie/inadvertent error” or a deliberate violation of the approved protocol can undermine the integrity of both the research process and the academic research enterprise.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
