West Virginia University research has revealed that college football coaches’ paychecks influence the quality of the players they’re able to recruit.

“College football coach salaries at big-time programs have increased substantially in recent years,” said Brad Humphreys, professor of economics at the WVU John Chambers College of Business and Economics. “We showed one reason for the increase is that colleges can recruit better athletes when they can offer them great coaches—and great coaches command higher salaries.”

Humphreys and professor Jane Ruseski have published their results in the journal Applied Economics.

“For decades, the National Collegiate Athletic Association, or NCAA, hasn’t allowed colleges or universities to compete for student-athletes on a price basis,” Humphreys explained. “Instead, the NCAA limited athletes’ compensation to the cost of attending college and schools began competing to attract players in non-monetary ways.

“That could mean lavish practice facilities or larger stadiums, or it could mean higher-quality coaches. Our work is the first to show that this non-price-based competition for athletes happened in an industry where no such competition was thought to exist.”

The 2021 Supreme Court decision in NCAA v. Alston allowed student-athletes to begin to profit from opportunities like brand endorsements, but the NCAA still largely restricts colleges to offering players scholarships that cover tuition, room, board and other costs of higher education. Big-time NCAA football and basketball programs bring in major revenues that–since they can’t go toward player compensation–pay the salaries of coaches and administrators.

“High-quality college coaches are better at developing athletes for post-college professional careers,” Humphreys said. “They generate wins, so athletes who play for high-quality coaches get to experience more victories, more championships. We found the bigger a head coach’s salary, the higher that coach’s quality and profile, and the more successful their team’s recruitment efforts.”

Humphreys and Ruseski estimated the effect of head coach salaries on recruiting success for 90 NCAA Division I-A football schools between 2006 and 2015. They used data including player rankings from 247Sports, which measures the quality of different schools’ recruiting classes.

The average score awarded to a recruiting class by 247Sports over the 2006 to 2015 seasons was 172. The researchers discovered that for every $1 million bump in the salary of the head coach, the quality score of the incoming recruiting class jumped by an average of 77 points.

“This is consistent with the presence of an arms race in intercollegiate athletics,” Humphreys said. “In an arms race, firms race to outdo each other not through price wars, but through strategies like facilities, equipment, product quality, customer service, personnel. Now NCAA institutions are engaged in an athletics arms race in the form of escalating coaches’ salaries and multimillion-dollar investments in facilities—a rational response to NCAA regulations that limit compensation to athletes.”

The study showed the average head football coach earned $1.8 million per season, with top earner Nick Saban bringing in more than $7.4 million in 2015 at the University of Alabama. But salaries veered sharply upward over the course of the study, Humphreys emphasized.

In 2006, the average head football coach in the sample earned about 14 times more than the average full-time faculty member. By 2015, the coach earned more than 26 times the faculty member’s salary.

Humphreys said he believes that the steep rise in coach compensation can’t be adequately explained by the “rising tide” of revenues earned by college football teams.

“Our results imply the increase in head football coach salaries represents strategic interaction among athletic departments as they compete for high-quality coaches. When one school gives a head coach a raise, competing schools will follow, creating an upward spiral in salaries. There are policy implications there, given that the head football coach at a state’s flagship public university is often the state’s highest-paid public employee.”

He said, “Some advocates of reform want Congress to enable college sports to put a salary cap on head coach compensation, but that may not be necessary after the decision in NCAA v. Alston. We’ll need to see how institutions adjust to an environment where athlete compensation beyond NCAA regulations is possible.”

Following Russia’s 2022 invasion of Ukraine, many companies with operations in Russia withdrew from or severely curtailed their Russian operations. For example, Dell and McDonald’s ceased all operations in Russia after the invasion.

Many experts have argued that the corporate response to the Ukraine war is a striking example of stakeholder capitalism, a model where corporations are responsible for considering the interests of various stakeholders—including employees, customers, communities, governments and the environment—and not just their shareholders. In contrast, opponents of the stakeholder view argue that firms should focus on the principal shareholders.

New research from the University of Notre Dame explores the impact of such corporate actions on consumer mindset metrics.

Decisions to withdraw from Russia since its invasion of Ukraine positively impacted consumer sentiment, especially for companies with strong environmental, social and governance (ESG) reputations, according to lead author Shankar Ganesan, the Raymond W. and Kenneth G. Herrick Collegiate Professor of Marketing at Notre Dame’s Mendoza College of Business, along with Girish Mallapragada from Indiana University.

Ganesan’s research, “Navigating Geopolitical Turmoil: Corporate Responses to the War in Ukraine and Its Impact on Consumer Mindset,” is forthcoming in the Journal of Public Policy and Marketing.

The Ukraine conflict serves as an important backdrop for the examination of corporate sociopolitical activism, where companies take public stances on controversial social and political issues.

Recent expansion in Russia by SLB (a global technology company formerly named Schlumberger) provides a stark contrast to the companies that withdrew from Russia following the invasion of Ukraine.

“This ongoing situation directly relates to our research,” said Ganesan, who studies interorganizational relationships and customer relationship management. “While many companies that withdrew from Russia saw a boost in consumer sentiment, SLB’s actions may test the limits of corporate reputation and consumer mindset in geopolitical crises.”

“SLB’s decision to continue and even expand operations in Russia, despite being labeled an international sponsor of war by Ukraine, presents a real-world case study of the potential long-term effects on brand reputation and consumer mindset metrics that our paper explores,” he said.

“It also highlights the complex interplay between corporate decisions, geopolitical pressures and consumer expectations in today’s global business environment.”

The study looked at the impact of these decisions on three critical consumer mindset metrics: net brand buzz, brand consideration set (group of products a buyer evaluates when making a purchase decision) and purchase intent. It also analyzed how these effects are moderated by factors such as a company’s ESG reputation, the timing of its decision relative to industry peers and whether the firm operates in a business-to-business (B2B) or business-to-consumer (B2C) context.

Companies that withdrew from Russian operations experienced a notable increase in net brand buzz, reflecting positive consumer sentiment over an eight-week period following the announcement, suggesting consumers generally favor companies that take a stand against geopolitical aggression.

The positive consumer sentiment was even stronger for companies with a robust ESG reputation. These firms saw enhanced brand consideration and purchase intent, indicating that a strong ESG profile can magnify the benefits of socially responsible actions during geopolitical crises.

“Interestingly, companies that delayed their withdrawal until after their industry peers saw a greater boost in net buzz,” Ganesan said. “This indicates that while early action is valued, there are strategic advantages to carefully timing such decisions in complex geopolitical environments.”

The research also uncovered variations in consumer reactions based on whether a company operates in a B2B or B2C context, providing nuanced insights for businesses on how different markets might perceive their actions during geopolitical crises.

This study contributes to understanding the relationship between such corporate actions and consumer mindset metrics in a novel geopolitical context, providing valuable insights for managerial decision-making and public policy.

When operating in politically sensitive regions, companies should account for the diverse interests of stakeholders, invest in ESG as a form of reputational insurance, carefully time major decisions, monitor consumer metrics and tailor strategies to industry context.

Ganesan challenges policymakers to understand the complex pressures businesses face during geopolitical crises and provide clear guidance that considers the varying impacts on B2B and B2C sectors.

He said, “By understanding the intricate relationship between corporate actions, geopolitical events and consumer perceptions, businesses can navigate these challenging waters more effectively, balancing ethical imperatives with business objectives.”

Move over Olympians, Australia’s wildlife are incredible athletes

Move over Olympians, Australia’s wildlife are incredible athletes

Now that the Paris Olympics and Paralympics have disappeared from our screens, let’s get back to watching animal videos.

But seriously, have you ever paused to think about the athletic abilities of Australian wildlife?

In my research as an ecologist, I’m constantly amazed by the strength, speed and resilience of our native animals. Their prowess is testament to the wonders of evolution, and the necessity of species having to adapt to challenging and changing environments in order to survive.

Let’s take a closer look at some of our best competitors and how might they fare, against humans and overseas entrants. On your marks, get set… swim, hop, dig, dance, glide!

Swimming

Australians are renowned for being strong swimmers. But what is the fastest swimmer in the animal kingdom?

On this there is much debate. Some suggest it’s the Indo Pacific sailfish, clocking in at about 30km/hr. That’s impressive, but much slower than oft-cited (but inaccurate) claims it can travel at more than 100km/hr.

For perspective, the fastest human to swim the 50 meters freestyle is American Caeleb Dressel, completing this in a time of 20.16 seconds. That’s roughly 9km/h—faster than many people jog, but still no match for a sailfish.

As in humans, swimming speed in fishes tends to increase with body length. Larger species that challenge sailfish for the fastest swimmer title include blue or black marlin. Shorter, torpedo-like bluefin tuna are also in contention. All are found in Australian waters, though not exclusively.






While American swimmer Michael Phelps put in an impressive showing against a simulated great white shark, no human would beat much faster sailfish, marlin and tuna.

Sprinting, long and high jump

Aussie icons, red kangaroos can reach speeds of around 60-70km/hr. But they are no match for cheetahs, which can move at more than 120km/hr.

Long jump is surely the kangaroo’s main event. Red kangaroos can jump a staggering 13 meters or more. Amazingly, this might not be enough to clinch gold. Snow leopards can jump more than 15 meters.

Kangaroos can clear heights of up to 3m, so would perform well in the high jump. But they’d finish behind bottlenose dolphins, which can jump over 7m in the air, just for kicks.

Scaled for body size, though, both species would be embarrassed by a tiny insect known as a froghopper. It jumps to heights of more than 140 times its body length.






Kangaroos sure can jump, but they’re not the greatest of all in the animal kingdom.

Battles of strength

African elephants can lift more than 1,000kg and weaver ants more than 100 times their own body weight.

But relative to size, a truly impressive champion is Australia’s horned dung beetle. At just a centimeter long, these diminutive powerhouses can pull more than 1,100 times their own body weight, roughly equating to an average man lifting two fully-loaded 18-wheeler trucks.

And yet, horned dung beetles might still only claim silver. Another invertebrate Aussie, the tiny tropical moss mite, is perhaps the world’s strongest animal. It can pull more than 1,180 times its weight.






Bigger does not always equal stronger.

Packing the fastest, deadliest punch

In terms of combat sports, bigger is not always better.

Peacock mantis shrimps—invertebrates found in Australian marine waters and elsewhere—have the swiftest and most powerful punch in the lightweight crustacean division.

They kill prey by punching them with strong, club-like appendages. They deliver blows at up to 23m per sec, akin to the speed and force of a .22 caliber bullet being fired.

So powerful is the punch, it vaporizes water and creates a super-hot shockwave that breaks up and incapacitates its prey.






Nature’s deadliest punch?

Tantalizing contests

What about a digging contest? Eastern barred bandicoots can shift 4.8 tons of soil a year. How would that stack up against marsupial moles, which can disappear almost instantly into desert sands? Or the expert excavations of wombats and aardvarks that can dig more than half a meter in 15 seconds?

In terms of free-diving and flying, there’s really no contest. Cuvier’s beaked whale can dive nearly 3000m and peregrine falcons can reach over 320 km/hr. These animals are found across the globe, however—not just in Australia.

Australia’s largest gliding marsupial, the greater glider, can sail up to 100m between trees. But gliding gold would surely go to the giant flying squirrel, which can glide up to 450m.

I’d love to see a shooting contest between Australia’s archer fish and Madagascar’s panther chameleon. But finding the right arena for both aquatic and land-based sharpshooters would be tricky.

Raygun’s kangaroo hop is now legendary, but a breaking (break dancing) contest between a peacock spider, spanish dancer (a type of nudibranch) and a magnificent riflebird might genuinely break the internet.

Appreciating wildlife athletes

So who would win a global contest for the best wildlife athlete overall?

If the competition was on land and focused on running, jumping, strength and climbing, it’s hard to go past the overall abilities of a Bengal tiger.

Many amazing wildlife athletes are threatened with extinction. Others are gone forever.

They include the incredible oolacunta—also known as the desert rat kangaroo. It’s powers of endurance in the desert are the stuff of folklore. As legendary Australian mammalogist Hedley Herbert Finlayson wrote in 1931:

“Its speed for such an atom, was wonderful, and its endurance amazing … when we finally got it, it had taken the starch out of three mounts and run us 12 miles; all under such adverse conditions of heat and rough going, as to make it almost incredible that so small a frame should be capable of such an immense output of energy.”

Let’s celebrate wildlife and their athletic abilities and ensure they have a secure future.

Researchers enhance efficiency of small electric drives for pumps and fans

Small electric motors can be found in many household appliances, tools and computers as well as in modern cars, where they drive auxiliary units such as pumps and fans. Individually, each of these motors does not consume much energy, but taken together they offer a great savings potential.

The research team of the recently completed “CD Laboratory for Brushless Drives for Pump and Fan Applications”, headed by Annette Mütze from the Electric Drives and Power Electronic Systems Institute at Graz University of Technology (TU Graz), has now further tapped into this potential. Thanks to innovative design, modified control technology and the use of new manufacturing techniques, the brushless integrated drives developed here consume less energy, operate more quietly and are lighter.

Slanted claws reduce vibrations

Larger claw pole motors are used in vehicle lighting systems, for example. Their use as small drive units is less well known. Mütze’s team has reduced the so-called “cogging torques” of these small drives by skewing and slotting the claws, which does not incur any additional costs. This minimizes the momentary engagement of the claws when the motor is turned, thus reducing unwanted vibrations.

“This enabled us to reduce an important source of noise by 70%. This means that the drives run much more smoothly and quietly,” says Mütze.

Simplified control reduces switching losses

Efficiency gains are achieved through simplified regulation of the current flow. Pulse width modulation usually regulates the current with which the motor of a fan or pump is supplied. In order for the current to flow in the desired rectangular pattern, a large number of switching operations are required, which, however, cause additional energy consumption.

“We only switch our drives on and off once per desired rectangle,” says Mütze. “This enabled us to considerably reduce the additional energy consumption caused by switching losses.”

Particularly at low currents, these drives therefore have a much better overall efficiency than those that are controlled via conventional pulse width modulation. Due to the drastically reduced number of switching operations, the circuit boards of the motors also require half as many capacitors, which reduces costs.

3D printing of ferrite-based material

The third innovation is the implementation of PCB motors with ferrite cores. “PCB” stands for “printed circuit board” and, in the case of motors, means that the windings that generate the magnetic field required for the drive are designed as printed circuit boards. This allows a high degree of automation in production.

Mütze’s team equipped the circuit boards with 3D-printed ferrite cores, which improved the guidance of the magnetic flux in the motors. This was the prerequisite for the use of more cost-effective magnets, which are also based on ferrite.

Johns Hopkins Medicine scientists who arranged for 48 human bioengineered heart tissue samples to spend 30 days at the International Space Station report evidence that the low gravity conditions in space weakened the tissues and disrupted their normal rhythmic beats when compared to Earth-bound samples from the same source.

The scientists said the heart tissues “really don’t fare well in space,” and over time, the tissues aboard the space station beat about half as strongly as tissues from the same source kept on Earth.

The findings, they say, expand scientists’ knowledge of low gravity’s potential effects on astronauts’ survival and health during long space missions, and they may serve as models for studying heart muscle aging and therapeutics on Earth.

A report of the scientists’ analysis of the tissues is published in the Proceedings of the National Academy of Sciences.

Previous studies showed that some astronauts return to Earth from outer space with age-related conditions, including reduced heart muscle function and arrythmias (irregular heartbeats), and that some—but not all—effects dissipate over time after their return.

But scientists have sought ways to study such effects at a cellular and molecular level in a bid to find ways to keep astronauts safe during long spaceflights, says Deok-Ho Kim, Ph.D., a professor of biomedical engineering and medicine at the Johns Hopkins University School of Medicine. Kim led the project to send heart tissue to the space station.

To create the cardiac payload, scientist Jonathan Tsui, Ph.D. coaxed human induced pluripotent stem cells (iPSCs) to develop into heart muscle cells (cardiomyocytes). Tsui, who was a Ph.D. student in Kim’s lab at the University of Washington, accompanied Kim as a postdoctoral fellow when Kim moved to Johns Hopkins University in 2019. They continued the space biology research at Johns Hopkins.

Tsui then placed the tissues in a bioengineered, miniaturized tissue chip that strings the tissues between two posts to collect data about how the tissues beat (contract). The cells’ 3D housing was designed to mimic the environment of an adult human heart in a chamber half the size of a cell phone.

To get the tissues aboard the SpaceX CRS-20 mission, which launched in March 2020 bound for the space station, Tsui says he had to hand-carry the tissue chambers on a plane to Florida, and continue caring for the tissues for a month at the Kennedy Space Center. Tsui is now a scientist at Tenaya Therapeutics, a company focused on heart disease prevention and treatment.

Once the tissues were on the space station, the scientists received real-time data for 10 seconds every 30 minutes about the cells’ strength of contraction, known as twitch forces, and on any irregular beating patterns. Astronaut Jessica Meir, Ph.D., M.S. changed the liquid nutrients surrounding the tissues once each week and preserved tissues at specific intervals for later gene readout and imaging analyses.

The research team kept a set of cardiac tissues developed the same way on Earth, housed in the same type of chamber, for comparison with the tissues in space.

When the tissue chambers returned to Earth, Tsui continued to maintain and collect data from the tissues.

“An incredible amount of cutting-edge technology in the areas of stem cell and tissue engineering, biosensors and bioelectronics, and microfabrication went into ensuring the viability of these tissues in space,” says Kim, whose team developed the tissue chip for this project and subsequent ones.

Devin Mair, Ph.D., a former Ph.D. student in Kim’s lab and now a postdoctoral fellow at Johns Hopkins, then analyzed the tissues’ ability to contract.

In addition to losing strength, the heart muscle tissues in space developed irregular beating (arrhythmias)—disruptions that can cause a human heart to fail. Normally, the time between one beat of cardiac tissue and the next is about a second. This measure, in the tissues aboard the space station, grew to be nearly five times longer than those on Earth, although the time between beats returned nearly to normal when the tissues returned to Earth.

The scientists also found, in the tissues that went to space, that sarcomeres—the protein bundles in muscle cells that help them contract—became shorter and more disordered, a hallmark of human heart disease.

In addition, energy-producing mitochondria in the space-bound cells grew larger, rounder and lost the characteristic folds that help the cells use and produce energy.

Finally, Mair, Eun Hyun Ahn, Ph.D.—an assistant research professor of biomedical engineering—and Zhipeng Dong, a Johns Hopkins Ph.D. student, studied the gene readout in the tissues housed in space and on Earth. The tissues at the space station showed increased gene production involved in inflammation and oxidative damage, also hallmarks of heart disease.

“Many of these markers of oxidative damage and inflammation are consistently demonstrated in post-flight checks of astronauts,” says Mair.

Kim’s lab sent a second batch of 3D engineered heart tissues to the space station in 2023 to screen for drugs that may protect the cells from the effects of low gravity. This study is ongoing, and according to the scientists, these same drugs may help people maintain heart function as they get older.

The scientists are continuing to improve their “tissue on a chip” system and are studying the effects of radiation on heart tissues at the NASA Space Radiation Laboratory. The space station is in low Earth orbit, where the planet’s magnetic field shields occupants from most of the effects of space radiation.
