Houston research: How social pressures are affecting digital product evaluations

Theoretically, product evaluations should be impartial and unbiased. However, this assumption overlooks a crucial truth about product evaluators: They are human beings who are concerned about maintaining credibility with their audience, especially their peer evaluators.

Because evaluators must also care about being perceived as legitimate yet skillful themselves, certain social pressures are at play that potentially influence their product reviews.

Research by Minjae Kim (Rice Business) and Daniel DellaPosta (Penn State) takes up the question of how evaluators navigate those pressures. They find that in some cases, evaluators uphold majority opinion to appear legitimate and authoritative. In other contexts, they offer a contrasting viewpoint so that they seem more refined and sophisticated.

Pretend a movie critic gives an uplifting review of a widely overlooked film. By departing from the aesthetic judgments of cinema aficionados, the reviewer risks losing credibility with their audience. Not only does the reviewer fail to understand this specific film, the audience might say; they fail to understand film and filmmaking, broadly.

But it’s also conceivable, in other situations, that the dissenting evaluator will come across as uniquely perceptive.

What makes the difference between these conflicting perceptions?

Partly, it depends on how niche or mainstream the product is. With large-audience products, Kim and DellaPosta hypothesize, evaluators are more willing to contradict widespread opinion. (Without a large audience, contradicting opinions are like the sound of a tree that falls in a forest without anyone nearby to hear.)

The perceived classiness of the product can affect the evaluator’s approach, as well. It’s easier to dissent from majority opinion on products deemed “lowbrow” than those deemed “highbrow.” Kim and DellaPosta suggest it’s more of a risk to downgrade a “highbrow” product that seems to require more sophisticated taste (e.g., classical music) and easier to downgrade a highly rated yet “lowbrow” product that seems easier to appreciate (e.g., a blockbuster movie).

Thus, the “safe spot” for disagreeing with established opinion is when a product has already been thoroughly and highly reviewed yet appears easier to understand. In that case, evaluators might sense an opportunity to stand out, rather than try to fit in. But disagreeing with something just for the sake of disagreeing can make people think you’re not a fair or reasonable evaluator. To avoid that perception, it might be better to agree with the high rating.

To test their hypotheses, Kim and DellaPosta used data from beer enthusiast site BeerAdvocate.com, an online platform where amateur evaluators review beers while also engaging with other users. Online reviewers publicly rate and describe their impressions of a variety of beers, from craft to mainstream.

The data set included 1.66 million user-submitted reviews of American-produced beers, including 82,077 unique beers, 4,302 brewers, 47,561 reviewers and 103 unique styles of beer. The reviews spanned from December 2000 to September 2015.

When the researchers compared scores given to the same beer over time, they confirmed their hypothesis about the conditions under which evaluators contradict the majority opinion. On average, reviewers were more inclined to contradict the majority opinions for a beer that had been highly rated and widely reviewed. When reviewers considered a particular brew to be a “lowbrow,” downgrading occurred to an even greater extent.

Kim and DellaPosta’s research has implications for both producers and consumers. Both groups should be aware of the social dynamics involved in product evaluation. The research suggests that reviews and ratings are as much about elevating the people who make them as they are about product quality.

Making evaluators identifiable and non-anonymous may help increase accountability for what they say online — a seemingly positive thing. But Kim and DellaPosta reveal a potential downside: Knowing who evaluators are, Kim says, “might warp the ratings in ways that depart from true objective quality.”

Houston researcher tapped for prestigious fellowship for offshore safety innovation

big win

A University of Houston professor has been selected by a national organization to “contribute to the understanding, management and reduction of systemic risk in offshore energy activities.”

The Gulf Research Program of the National Academies of Sciences, Engineering, and Medicine announced that Harish Krishnamoorthy, assistant professor of electrical and computer engineering at the University of Houston, is one of four selected early-career research fellows in the Offshore Energy Safety track. Krishnamoorthy is the first researcher from UH selected for the recognition.

“I am happy and honored to be the first one, but hopefully there will be a lot more in the coming years,” Krishnamoorthy says in a UH news release.

The award, which isn't granted based on a specific project, includes a $76,000 grant, mentor support, and access to a network of current and past cohorts.

Created in 2013, the program is an independent, science-based program founded as part of legal settlements with the companies involved in the 2010 Deepwater Horizon disaster. Its goal is "to enhance offshore energy system safety and protect human health and the environment by catalyzing advances in science, practice and capacity, generating long-term benefits for the Gulf of Mexico region and the nation," the release reads.

“These exceptional individuals are working hard to pursue new research, technical capabilities, and approaches that address some of the greatest challenges facing the Gulf and Alaska regions today,” says Karena Mary Mothershed, senior program manager for the Gulf Research Program’s Board on Gulf Education and Engagement. “We are incredibly excited to announce these new Early-Career Research Fellows, and to continue supporting them as they make lasting impacts.”

Krishnamoorthy, who also serves as associate director of the Power Electronics, Microgrids and Subsea Electric Systems Center at UH, has expertise is in power electronics, power converters, and offshore technologies. His research interests include high-density power conversion for grid interface of energy systems, machine learning-based methods for improvement in quality and reliability of power electronics, advanced electronics and control for mission-critical applications.

According to Krishnamoorthy, there are around 1,500 offshore rigs — with a large amount located North Sea and the Gulf of Mexico. There's a need to improve existing systems, according to Krishnamoorthy, and this process of evolving the grid comes with safety risks and challenges.

“When there are so many electronics involved, safety and reliability are going to be very critical,” Krishnamoorthy says in he release. “I have been looking at safety aspects a lot in my research as well as how to connect subsea oil and gas systems with offshore renewable systems.”

In 2022, Krishnamoorthy was recognized as an OTC Emerging Leader at the Offshore Technology Conference for his contributions to offshore safety and workforce development in offshore, as well as reducing the carbon emissions.

Houston research: The future of decision making in energy operations

houston voices

Real options represent the decisions companies can make in the face of evolving risk. In the energy and commodity industries, real options are ubiquitous, including the extraction, processing and refinement, storage, and transportation of natural resources. These choices are influenced by ever-changing market and environmental conditions.

Because of these uncertainties, the energy industry has been a key focus of the operations literature on real options. Rice Business professor Nicola Secomandi, along with University of Illinois at Chicago College of Business Administration professor Selvaprabu Nadajarah, were recently invited by the European Journal of Operational Research to conduct a review of the operations literature on real options in energy. Their review included 80 papers across 10 journals active in the field. The research was mostly conducted during Secomandi’s time at the Tepper School of Business at Carnegie Mellon University.

The review examined how often different types of energy and methods of studying related business processes appeared in the operations literature. Nearly a quarter of the papers considered natural gas, more often than any other energy type. Natural gas storage was the most studied process, while the transport and sale of natural gas were less discussed.

While only 10 percent of the papers focused on electricity by itself, mostly in the context of battery management, electricity was discussed alongside emissions and the environment in 22.5 percent of the papers—almost as often as natural gas. About 11 percent of the papers examined both electricity and natural gas.

Roughly 21 percent of the papers focused on crude oil and refined products. Exploration, development, and abandonment of crude oil fields were common topics, while work on crude oil refining and gasoline logistics was rarer.

The review looked at the frequency of use of five categories: real option types, valuation methodologies, model formulations, price risk dynamics, and optimization schemes. Timing options, which irreversibly change the status of an asset when exercised, and switching options, which involve reversible changes, appeared with about equal frequency. Of the valuation methodologies, risk neutral valuation was employed the most often, appearing in nearly 78 percent of the papers. Model formulations were divided mainly between Markov decision processes, which assume that decisions are made at set times, and stochastic optimal control models, which assume that decisions are made continuously. About 63 percent of the papers discussed Markov decision processes, but at nearly 34 percent, stochastic optimal control models haven’t been entirely left out of the literature. Almost 75 percent of the papers formulated models based on spot prices as opposed to futures prices, and over 80 percent adopted normal distribution models, either alone or in combination with other models. Approximate solution approaches dominated within optimization schemes, appearing in 71 percent of the papers.

While several energy sources and analysis tools have been discussed in the literature, the possibilities for future research remain broad. The transition to clean energy sources may increase the complexity of already intricate operations. Its modeling and analysis may require more advanced models than existing ones.

We're living in the age of machine learning and artificial intelligence. Miguel Tovar/University of Houston

Now is the time to expand machine learning, says Houston researcher

Houston voices

One might not expect the game of checkers to have anything to do with artificial intelligence, but the game really marked the beginning of machine learning in 1959. Pioneered by an MIT professor named Arthur Lee Samuel, it was discovered that teaching a simple strategy game to a computer is not so simple when every move needs to be anticipated.

Smart machines Additionally, in a Forbes article about the difference between artificial intelligence and machine learning, Bernard Marr comments, "Artificial Intelligence is the broader concept of machines being able to carry out tasks in a way that we would consider 'smart'. And, machine learning is a current application of AI based around the idea that we should really just be able to give machines access to data and let them learn for themselves."

That's the premise of many a movie involving computers which become sentient, but is it really science fiction anymore?

Meet the new boss

Teaching a computer to think like a human is advantageous and includes the added bonus of increased speed. Computers aren't biased, either — which is why huge corporations, such as Unilever, use computers to thin out their first wave of applicants. You actually interview with a bot when you begin the employment process there.

Cause and effect AI and ML are often used in cybersecurity efforts — at least one would suppose. But in Security magazine, Jordan Mauriello writes: "AI/ML cannot do causation." That means artificial intelligence cannot, at this point in time, tell you why something happened. The why? is best left to experts who deal with game theory and other ways of determining how to defend against hypothetical attacks.

Get in on the ground floor

The field is growing and students at colleges across the country are beginning to train for careers in it in droves.

"America's top colleges are ramping up their research efforts and developing concentrations for their computer science degree programs to accommodate this high-tech field," writes Great Value Colleges on their blog. It looks as though this discipline is on an upward trajectory and shows no sign of slowing down.

Houston expert shares why prototyping is so important to startups

Making a product that is worth further investing in, one that customers will want to buy, requires several prototypes, sometimes tens of prototypes to prove the concept and perfect your idea. Photo courtesy of OKGlobal

Rarely in life is anything perfect on the first attempt. Writers write drafts that are proofed and edited. Musicians practice over and over, and athletes train for years to perfect their skills before becoming pros. So, it only makes sense that a product developer would develop a prototype before manufacturing their products.

But why? Why can't a perfectly designed product go straight from CAD to production? In reality, making a product that is worth further investing in, one that customers will want to buy, requires several prototypes, sometimes tens of prototypes to prove the concept and perfect your idea. Success comes through practice, just like with the musicians and the athletes. Read more.

Texas plugs in among states at highest risk for summer power outages in 2025

hot, hot, hot

Warning: Houston could be in for an especially uncomfortable summer.

A new study from solar energy company Wolf River Electric puts Texas at No. 2 among the states most at risk for power outages this summer. Michigan tops the list.

Wolf River Electric analyzed the number of large-scale outages that left more than 5,000 utility customers, including homes, stores and schools, without summertime electricity from 2019 to 2023. During that period, Texas experienced 7,164 summertime power outages.

Despite Michigan being hit with more summertime outages, Texas led the list of states with the most hours of summertime power outages — an annual average of 35,440. That works out to 1,477 days. “This means power cuts in Texas tend to last longer, making summer especially tough for residents and businesses,” the study says.

The Electric Reliability Council of Texas (ERCOT), which operates the electric grid serving 90 percent of the state, predicts its system will set a monthly record for peak demand this August — 85,759 megawatts. That would exceed the current record of 85,508 megawatts, dating back to August 2023.

In 2025, natural gas will account for 37.7 percent of ERCOT’s summertime power-generating capacity, followed by wind (22.9 percent) and solar (19 percent), according to an ERCOT fact sheet.

This year, ERCOT expects four months to surpass peak demand of 80,000 megawatts:

  • June 2025 — 82,243 megawatts
  • July 2025 — 84,103 megawatts
  • August 2025 — 85,759 megawatts
  • September 2025 — 80,773 megawatts

One megawatt is enough power to serve about 250 residential customers amid peak demand, according to ERCOT. Using that figure, the projected peak of 85,759 megawatts in August would supply enough power to serve more than 21.4 million residential customers in Texas.

Data centers, artificial intelligence and population growth are driving up power demand in Texas, straining the ERCOT grid. In January, ERCOT laid out a nearly $33 billion plan to boost power transmission capabilities in its service area.

Houston ranks among top 5 cities for corporate HQ relocations in new report

h-town HQ

The Houston area already holds the title as the country’s third biggest metro hub for Fortune 500 headquarters, behind the New York City and Chicago areas. Now, Houston can tout another HQ accolade: It’s in a fourth-place tie with the Phoenix area for the most corporate headquarters relocations from 2018 to 2024.

During that period, the Houston and Phoenix areas each attracted 31 corporate headquarters, according to new research from commercial real estate services company CBRE. CBRE’s list encompasses public announcements from companies across various sizes and industries about relocating their corporate headquarters within the U.S.

Of the markets included in CBRE’s study, Dallas ranked first for corporate relocations (100) from 2018 to 2024. It’s followed by Austin (81), Nashville (35), Houston and Phoenix (31 each), and Denver (23).

According to CBRE, reasons cited by companies for moving their headquarters include:

  • Access to lower taxes
  • Availability of tax incentives
  • Proximity to key markets
  • Ability to support hybrid work

“Corporations now view headquarters locations as strategic assets, allowing for adaptability and faster reaction to market changes,” said CBRE.

Among the high-profile companies that moved their headquarters to the Houston area from 2018 to 2024 are:

  • Chevron
  • ExxonMobil
  • Hewlett-Packard Enterprise
  • Murphy Oil

Many companies that have shifted their headquarters to the Houston area, such as Chevron, are in the energy sector.

“Chevron’s decision to relocate its headquarters underscores the compelling advantages that position Houston as the prime destination for leading energy companies today and for the future,” Steve Kean, president and CEO of the Greater Houston Partnership, said in 2024. “With deep roots in our region, Chevron is a key player in establishing Houston as a global energy leader. This move will further enhance those efforts.”

According to CBRE, California (particularly the San Francisco Bay and Los Angeles areas) lost the most corporate HQs in 2024, with 17 companies announcing relocations—12 of them to Texas. Also last year, Texas gained nearly half of all state-to-state relocations.

In March, Site Selection magazine awarded Texas its 2024 Governor’s Cup, resulting in 13 consecutive wins for the state with the most corporate relocations and expansions.

In a news release promoting the latest Governor’s Cup victory, Gov. Greg Abbott hailed Texas as “the headquarters of headquarters.”

“Texas partners with the businesses that come to our great state to grow,” Abbott said. “When businesses succeed, Texas succeeds.”

CBRE explained that the trend of corporate HQ relocations reflects the desire of companies to seek new environments to support their goals and workforce needs.

“Ultimately, companies are seeking to establish themselves in locations with potential for long-term success and profitability,” CBRE said.

SpaceX test rocket explodes in Texas, but no injuries reported

SpaceX Update

A SpaceX rocket being tested in Texas exploded Wednesday night, sending a dramatic fireball high into the sky.

The company said the Starship “experienced a major anomaly” at about 11 pm while on the test stand preparing for the 10th flight test at Starbase, SpaceX’s launch site at the southern tip of Texas.

“A safety clear area around the site was maintained throughout the operation and all personnel are safe and accounted for,” SpaceX said in a statement on the social platform X.

CEO Elon Musk ’s SpaceX said there were no hazards to nearby communities. It asked people not to try to approach the site.

The company said it is working with local officials to respond to the explosion.

The explosion comes on the heels of an out-of-control Starship test flight in late May, which tumbled out of control. The FAA demanded an investigation into the accident.
