Communication studies expert attacks myths about harms of social media

 

LAWRENCE — Australia just banned social media for those under 16.

Before U.S. or any other lawmakers try to ban social media for any group of people, a University of Kansas professor of communication studies who has studied the issue deeply has busted some of the most egregious myths about the supposed harms of its use.

In “Ten Myths About the Effect of Social Media Use on Well-Being,” published in the 25th anniversary edition of the Journal of Medical Internet Research, Jeffrey Hall sets out 10 of the most commonly heard claims about the harms of social media — including its supposed toxicity and trigger for depression — then reviews the latest social scientific research to knock them down.

He likens social media use less to tobacco use and more to eating a doughnut: not alone a healthy diet, but not inherently harmful and with some nutritional value.

Hall spent a yearlong fellowship at the Berkman Klein Center for Internet & Society at Harvard University Law School combing through the latest research on the association between well-being and social media use. Hall writes that he approaches the subject of well-being from a broad perspective, considering both its deepest level — “meaning, connection and life purpose” — as well as transitory states like “pleasure, enjoyment and entertainment.”

In recent years, Hall has gained acclaim for his research on social media and directs KU’s Relationships and Technology Lab.

In the new paper, he points to studies showing no harm, or, in some cases, mixed effects from social media use, and he examines problems with measurement and methodology in other studies — for example, on so-called social media addiction.

“Internet addiction is a great example where the methods are flawed,” Hall said. “There is no conclusion among researchers that existing measures are meaningful indicators of addiction. It is very difficult to say that harms are caused by media use. Instead, social media use is probably either a coping mechanism or a manifestation of underlying issues that are leading to the compulsive use.”

Nor, Hall writes, is there evidence that bans do any good in ameliorating the supposed harms: “Studies that require participants to abstain from social media for a week or more report no changes in daily loneliness, affective well-being and positive or negative affect,” he writes.

He cautions against social media bans, noting that many people get their real-life needs met online.

“There are many positive attributes about social media use, but the claims and the discussion that we are having, broadly speaking, are almost all about its most negative effects,” Hall said. “Social media are used in a range of ways. You see some stuff that makes you feel sad and upset and stressed and frustrated, and then you also see things that make you feel uplifted and more connected to humanity. Social media are used to keep in touch with friends and family and to share experiences. So to say that it’s undeniably toxic or that it absolutely will cause depression or harm, it’s just not consistent with the literature.”

Yet the goal of the paper is not to let social media off the hook, Hall said. In the place of each myth, he offers a research-warranted claim.

“It’s not to deny that, for some users, social media use is associated with negative outcomes,” he said. “It’s not to say that social media is an effective way to cope with a preexisting problem. What I’m saying is that the claims about social media tend to be more exaggerated and less based on research than they should be in order to have a quality public debate about their effects.”

Rather than likening social media to tobacco use, Hall said, “Perhaps social media functions like a social snack, temporarily redirecting or distracting users from negative effect or loneliness, but failing to fully satisfy their needs.”

“In the big picture, consuming a doughnut is not going to really change the direction of your life. But eating doughnuts to try to solve life’s problems is going to create new problems.”

The last myth Hall busts is that no more research is needed on social media, that proof of their alleged harms is definitive and certain. On the contrary, he writes, social media is ever-changing, and so should be the research that seeks to understand the effects of its use.

For spring gardens, start transplants now

0
Onions, many other vegetables need time to germinate before spring planting.

Spring gardens may seem distant in the midst of winter, but Kansas State University horticulture expert Cynthia Domenghini says it’s not too early to begin gathering seeds for the coming season.

In fact, many vegetables need to be started in January if gardeners intend to transplant them to the outdoor garden in March or April.

“Transplants for the vegetable garden typically require 4-6 weeks from seeding to transplant date,” Domenghini said.

Onions take longer, as much as 10-12 weeks. Domenghini said guidelines for vegetables commonly grown in Kansas are available in the Kansas Garden Guide, available from the K-State Research and Extension bookstore.

Look for the Average Expected Planting Calendar to determine when to start vegetable transplants.

For most vegetables, Domenghini offers the following tips for starting transplants indoors:

  • Always use a disease-free, soilless planting media or seed-starting mix for seeds. The containers for seed-starting mix can be individual cups, trays or even recycled containers as long as they have drainage holes in the bottom.
  • Fill the container with two inches of media and lightly cover the seeds with the mix after planting. Keep the soil moist until the seeds germinate, and keep the containers under lights in a warm location.
  • When the seedlings have grown 2-4 small leaves, they are ready to be transplanted into small pots. This will allow them to continue growing until it’s time to transplant them into the garden.

“It’s important to give plants time to harden off before transplanting,” Domenghini said. “This should typically be started 10 days before the transplant date, and involves gradually acclimating the seedlings to the outdoor conditions by reducing the amount of water the plants receive, while slowly increasing their exposure to outdoor conditions.”

Starting onions indoors

Onions are typically planted in late March to avoid summer heat, so if growing them from seed, the plants need to be started 10-12 weeks before transplant date. That means as early as mid-January.

To start onions indoors, Domenghini suggests:

  • Place seeds ½ to 1 inch apart in a tray filled with seed-starting media. Keep the tray in a warm location (75-80 degrees Fahrenheit) until seeds germinate.
  • When the seedlings are 1-2 inches tall, move the tray to a cooler location (60-65 F).
  • Provide adequate light and use a water-soluble, general-purpose fertilizer no more than once per week when seedlings reach 2-3 inches in height.

Domenghini and her colleagues in K-State’s Department of Horticulture and Natural Resources produce a weekly Horticulture Newsletter with tips for maintaining home landscapes and gardens.

Interested persons can subscribe to the newsletter, as well as send their garden and yard-related questions to [email protected], or contact your local K-State Research and Extension office.

Houseplants are fun

0

Houseplants are fun to have year round. They do have care requirements to keep them happy and healthy. One of these requirements is nutrition. Houseplants should not be fertilized with a consistent amount of fertilizer throughout the year. The amount required depends on the season. Normally houseplants that rely on natural sunlight are not fertilized at all from November through February as the light levels are so low that fertilizer is not needed. The light intensity is less during the winter as the sunlight must pass through more of the atmosphere resulting in less light energy. Also, the days are shorter resulting in even less light available for growth. Fertilizing during these dark months can do harm. Fertilizer are salts and can build up in the soil if the plant doesn’t take them up due to slow growth. Eventually the fertilizer salt content can reach a level that roots are burned.

 

So, what is a simple method for fertilizing houseplant? Fertilize at the rate recommended on the label of your fertilizer from March through October. Don’t fertilize at all during November through February unless the plants are receiving supplemental lighting. If they are, then fertilize the same amount throughout the year.

 

If your fertilizer recommends fertilizing once a month, try splitting the concentration recommended in half and fertilize twice a month. The total amount is the same but the frequency is doubled which may result in a more efficient use of the fertilizer.

$2.5M grant will support nature-based study of pathogen resistance in perennial crop systems

 

LAWRENCE — Plant pathogens — microorganisms and other disease-causing agents — can wreak havoc on agricultural and forest crop plantings, as well as rangeland. Managing annual monoculture crops to resist disease means using specific products or practices to disrupt the pathogen population.

But researchers think an altogether different strategy could work in an alternate system: perennial polyculture.

University of Kansas scientists and their collaborators believe, based on their previous research, that this approach could lead to more durable resistance in perennial crops: mimicking nature and using mixed strategies — including breeding for resistance and planting in multispecies polycultures.

A new five-year, $2.5 million grant will support a KU-led project exploring this approach in a potential perennial oilseed crop, silflower (Silphium integrifolium). The project is funded through the federal program on Ecology and Evolution of Infectious Diseases (EEID), a joint effort of the National Science Foundation, the National Institutes of Health and the U.S. Department of Agriculture.

The principal investigator is Jim Bever, KU Foundation Distinguished Professor of Ecology & Evolutionary Biology and senior scientist at the Kansas Biological Survey & Center for Ecological Research. Collaborating institutions are The Land Institute in Salina, the Danforth Plant Science Center in St. Louis and Case Western Reserve University in Cleveland.

“We already know that the impact of pathogens goes down with species diversity in plant communities,” Bever said. “This is common in prairie plant communities, and it brings significant increases in productivity. In terms of a crop, that means overproducing.”

Researchers will evaluate the drivers of foliar disease in silflower — specifically the relative importance of two factors: breeding for genetic resistance and planting in multispecies mixtures. The results could guide future breeding efforts and planting designs.

“My hope and expectation is that planting diverse species mixes can mean more robust resistance to pathogens than you’d get only using a genetic approach,” Bever said. “Reliance only on breeding for resistance is hard because you’re only addressing one pathogen at a time, and the pathogen is always evolving.

“Diversity in planting can give plants resistance to more pathogens at once, and that can make resistance more difficult for the pathogen to overcome. So it follows that planting diverse mixes also could reduce the need to put effort into breeding for pathogen-specific resistance.”

The project runs from the beginning of 2025 through the end of 2029, with field research sites in Lawrence and Salina.

The Kansas Biological Survey & Center for Ecological Research is a KU designated research center, housing a diverse group of programs in ecological research and remote sensing/GIS. It also manages the 3,200-acre KU Field Station, a resource for KU studies in the sciences, arts, humanities and professional schools, and for the community and other institutions.

As cheerleading gets competitive, a Kansas City doctor wants to make it safer from concussions

0
A Kansas City doctor and the American Academy of Pediatrics have issued a report analyzing the unique injury risks in cheerleading and how to improve safety for the first time in over a decade. They’re calling for a series of changes, including broad recognition of cheerleading as a sport.

It’s late on a Tuesday night in December and a handful of cheerleaders are ironing out their routine at Triple Threat KC, a gym in Lenexa.

The gym’s advanced team is preparing for competitions later this month: one in Sedalia where they’ll square off against 75 teams, and another in Kansas City featuring more than 100 teams. They’re working on new stunts — aerial maneuvers that involve jumping, tumbling and tossing cheerleaders into the air — in hopes of winning.

Despite those ambitions, Charles Moore, the gym’s owner and coach, wants to make sure his athletes don’t put success over safety.

He says a good stunt can look incredibly complex, but if he breaks it down step by step — he compares it to a Lego set — it helps kids understand what the movement is supposed to look and feel like when they stick the landing.

For each person someone hoists into the air — the flyer — there is at least one back spotter, often a coach.

“If I can get somebody to practice something in a safe environment where they know they aren’t going to get injured they’ll give full effort to the technique,” Moore says. “It’s when they don’t feel safe when they try to get it over as fast as possible.”

Cheerleading is the fastest-growing female sport in the country. Most of the 3.5 million kids participating are girls between the ages of six and 17. The Kansas City metro has more than a dozen all-star cheer gyms, and most schools have some sort of cheer team.

What was once a grounded, male-dominant activity meant to energize school spirit through chants has grown to be incredibly athletic and complex. That’s why, for the first time in over a decade, doctors with the American Academy of Pediatrics have issued a report analyzing the unique injury risks in cheerleading and how to improve safety.

Dr. Gregory Canty of Children’s Mercy Hospital in Kansas City co-authored the November statement by the American Academy of Pediatrics released. In his medical practice, Canty treats cheerleading patients every day. He’s seen concussions, broken bones and catastrophic injuries.

“Because of that risk, we need to do everything we can as parents, as physicians and as a community to continue to make the sport safer,” Canty says.

Conflicting data

Overall, considering the rapid growth of the sport, Canty and his co-authors say there’s been a decrease in the rate of injuries for female cheerleaders.

Their report suggests the overall rate of injury in cheerleading is two to three times lower than in girls’ soccer or basketball, for example. But cheerleading injuries, particularly concussions, can be especially severe and have a prolonged recovery time.

Stunting is 70% of the concussions reported in high school cheerleading, according to the report. And concussions suffered during cheerleading practice rank third behind boys’ football and wrestling practices.

“Cheer appears to be one of the safer sports from the places we got data, but there is data that suggest when cheerleaders do get injured the risk of a serious injury is there,” Canty says. “Some of those can be things like concussions, fractures, dislocations, those types of injuries. You have to be alert to those types of things that could keep you away for more than a couple of weeks.”

Canty notes one big change is concussion recognition, and that could be why there are a greater number of concussions reported now than in the previous report in 2012. But Canty also says data reporting on the sport isn’t great.

There’s no database where all gyms and schools report cheer injuries, so collection can be piecemeal. That’s something to consider when reviewing overall rates, says Kimberly Archie, a founder of the National Cheerleading Safety Foundation – established by former coaches, cheerleaders and their parents.

And sometimes, injuries might be mislabeled as gymnastics-related because of the similarities in some of the moves, Archie says.

She points to other research done in collaboration with the National Center for Catastrophic Sports Injury Research that suggests the number of catastrophic injuries sustained by cheerleaders is greater than the sum of all female athletes playing other high school or college sports combined.

“It’s prevalent, it’s been normalized and it’s causing a health epidemic in cheerleading,” Archie says. “Cheerleaders aren’t just at risk of arthritis or knee problems, but to have brain health issues for the rest of their life.”

Brittany Poinson at Children’s Hospital New Orleans reports seeing “quite a few cheerleaders for persistent post-concussion symptoms,” according to reporting by NPR.

But USA Cheer, an organization overseeing safety regulations recognized by various Olympic committees, says those metrics are outdated and there have been great strides in addressing these injury concerns in the past few decades.

Nearly twenty years ago, several of the sport’s governing bodies changed requirements for the basket toss. That’s when a team of people whose hands are interlocked launches a cheerleader into the air.

A study on catastrophic injuries later found that making sure teams did the move on absorbent surfaces, like grass or rubber mats, made it four times safer over the next decade.

Overcoming bias and finding a path forward

Canty says other changes would make the sport even safer.

A major step would be state associations and high school athletic departments overseeing and formally recognizing cheerleading as a sport.

“It would solidify cheerleader’s access to trained individuals, to making sure they have athletic trainers that are available, they have strength and conditioning personnel,” Canty says. “All those things kind of open up.”

Canty says this would also help improve injury reporting and data collection.

Kansas and Missouri already list cheer as a sport under their high school athletic associations. But Archie says cheer must also be recognized under Title IX – the federal law that prohibits sex discrimination and ensures students in educational settings are treated equally.

Without that, Archie says, school teams don’t feel any real legal pressure to abide by regulations. That includes having an emergency action plan, which the AAP report says should be commonplace and clearly posted in all schools and gyms.

“Think about the janitor at the school district,” she says. “If they get up on a ladder above six feet, they need a fall protection plan. High school cheerleaders often do acrobatics and tumbling above six feet and they don’t have a fall protection plan.”

Archie knows this from firsthand experience. Her daughter broke an arm at cheerleading practice, and there was no plan in place for getting her help.

One roadblock to Title IX and broad recognition is a bias against cheerleading, Archie says. Depending on your age or exposure to the sport, you might still see it as the pom-pom-waving sport it was decades ago. It’s also the only sport with its own category on PornHub, Archie says.

“When I say that people are pretty taken aback, but it affects how seriously people take this issue,” she says.

Another roadblock is the organizations charged with oversight of the sport. While USA Cheer supports high schools and colleges recognizing and regulating the sport, it does not support placing cheerleading under Title IX. USA Cheer and Varsity Spirit, an organization that helped create USA Cheer and holds a near monopoly over the sport — have routinely opposed Title IX certification in court.

Jim Lord, USA Cheer’s director of education and programs, says that’s because under Title IX, teams should be competitive in nature and not every sport is.

“In Missouri and in Kansas they have requirements for training either for their coaches, the same types of training that other sports coaches have to follow,” Lord says. “They provide opportunities for competition, but also they make them follow the safety rules and they do that without being necessarily a Title IX type of sport.”

Many teams are also uneasy about speaking on the issue. Out of eight teams KCUR contacted around the Kansas City metro, only Triple Threat KC responded.

Lord says that’s because of media scrutiny unfairly characterizing the issue. Archie, however, says she suspects organizations like Varsity and USA Cheer want to keep the problems quiet.

Ground level changes

In its policy statement, the AAP also calls for physical health screenings for prospective athletes. Lord says USA Cheer supports all the recommendations in the report.

Many of them, such as physicals and an emergency action plan, are already suggested by USA Cheer. But they are just recommendations. Lord says the organization has its own safety council made up of doctors, trainers, surgeons and other experts who review new data yearly to make necessary changes.

They will meet in February to go over the rules for high school and in April for college.

“We’ll be bringing all those things together to see if there are rules out there we have been allowing that we have a concern about and whether we need to address those through education or if we’ve done that, to make a rule change,” Lord says.

With large-scale changes such as Title IX recognition unlikely to happen in the immediate future, individual gyms and schools can still institute things like an action plan to help keep more kids out of Dr. Canty’s clinic at Children’s Mercy.

At Triple Threat KC, Moore requires all cheerleaders to get a physical before they join the gym. And he is especially particular about concussions.

“We have a concussion protocol so that a way we can check the symptoms of a concussion and if I deem it a light to moderate concussion, we’re shutting it down,” he says. “It’s not worth the risk. The brain is a significant organ and we want to make sure it’s working at all times so we’re gonna shut it down.”
