Dispositional optimism and cognitive functioning following traumatic brain injury

The association of dispositional optimism with health-related factors has been well established in several clinical populations, but little is known about the role of optimism in recovery after traumatic brain injury (TBI). Given the high prevalence of cognitive complaints after TBI, the present study examined the association between optimism and cognitive functioning after TBI.

Big oil overreaches on COVID-19 bailout

Like everyone, U.S. oil companies have been hit hard by the pandemic, and they are looking for relief. . Oil companies have requested special access to a $600 billion lending facility at the Federal Reserve, and the administration seems keen to deliver. The president just announced that the Secretary of Energy and Secretary of the Treasury would make funds available, and the Department of Energy is also floating a $7 billion plan to pay drillers to leave oil in the ground.

Unfortunately, at least one faction of the industry — a group of refiners that traditionally profit when crude feedstocks are cheap — is angling for much more than a financial bailout. They are using the pandemic as cover to cannibalize markets vital to U.S. biofuel producers and farmers.

Their plan, outlined in letter from several oil-patch governors, would require the Environmental Protection Agency (EPA) to halt enforcement of the Renewable Fuel Standard (RFS). It would allow refiners to stop offering biofuel blends at the fuel pump, eliminating the market for U.S. ethanol and biodiesel and decimating demand for billions of bushels of corn and soybeans used to make renewable motor fuel.

With half the nation’s 200-plus biofuel plants already offline, thousands of rural workers facing layoffs, and millions of U.S. farmers on financial life support, the destruction of the RFS would be an economic death knell for rural America.

It’s hard to imagine why refiners would expect the Trump administration to take the request seriously. The misguided plan would inflict incredible collateral damage on our economy, our energy security, and to the President’s prospects with rural voters. Notably, the courts rejected similar abuse in 2016. Even former EPA Administrator Scott Pruitt, who scorned American farmers, rejected a similar plan back in 2017.

Nevertheless, refiners saw the current health crisis as a political opportunity and went for a kill. Fortunately, farm state champions are pushing back. Governors from Kansas, Iowa, Nebraska, South Dakota and Minnesota condemned the oil-backed plan. They wrote, “Using this global pandemic as an excuse to undercut the RFS is not just illegal; it would also sever the economic lifeline that renewable fuels provide for farmers, workers and rural communities across the Midwest.”

Aside from the sheer audacity, the refinery-backed plan also suffers from a major flaw — it wouldn’t change the economic situation of a single refinery. They claim that lifting the RFS would eliminate the costs associated with biofuel credits known as RINs, which are used to demonstrate compliance with the nation’s biofuel targets. Refiners that refuse to produce biofuel blends can purchase RINs from those that blend more ethanol or biodiesel into the fuel mix. In turn, when they sell a gallon of fuel, that RIN price is reflected in their returns. The oil industry’s own reports show that “there is no economic harm to RIN purchasers, even if RIN prices are high, because those costs are recouped in the gasoline blend stock and diesel.”

Even in a fictional scenario where costs aren’t automatically recouped, a detailed EPA analysis found that “all obligated parties, including the small refiners subject to the RFS program, would be affected at less than 1 percent of their sales (i.e., the estimated costs of compliance with the rule would be less than 1 percent of their sales) even when we did not consider their potential to recover RIN costs — with the estimated cost-to-sales percentages ranging from -0.04 percent (a cost savings) to 0.006 percent.”

Clearly, a 0.006 percent savings isn’t going to protect any refinery jobs, but refineries are betting that DC policymakers don’t know the difference between RINs values and compliance costs. They open one side of a ledger and hope that no one asks to see the next page.

Meanwhile, the nation’s biggest oil lobby, American Petroleum Institute, is calling on the EPA to simply cut 770 million gallons of biofuel out of the 2020 targets. Earlier this year, regulators approved a modest bump in biofuels to addresses a small fraction of the four billion gallons lost to secretive EPA refinery exemptions. The courts have since sided against the handouts, but the EPA has refused to implement the decision. Now, API says the agency should rip away the few gallons clawed back by U.S. farmers. It’s a baseless argument with one goal: blocking competition at the fuel pump.

Keep in mind, collapsing demand for motor fuel is just as hard on the nation’s biofuel producers. RFS targets enforced by the EPA are based on a percentage of each gallon sold — so if refiners make less fuel, their obligations under the law shrink at an equal rate. Meanwhile, biofuel producers across the heartland are closing their doors, as even their modest 10 percent share of the market has been cut in half.

Biofuel advocates are focused on their own survival. Iowa Sen. Chuck Grassley summed it up, saying “[T]here ought to be parity for all liquid fuels. So I look forward to working with (Agriculture) Secretary (Sonny) Perdue to make sure that our biofuels industry gets through this crisis so that we can continue to use America’s (home) grown energy in our gas tanks.”

Parity makes sense, but refinery lobbyists want more. The Trump EPA should reject the latest anti-biofuel pitch because it’s bad policy, but more than that, it’s an insulting attempt to capitalize on a health crisis to make an end run around the truth.

Former Missouri Sen. Jim Talent spearheaded the Renewable Fuel Standard in 2005. He currently serves as co-chair of Americans for Energy Security and Innovation.

Controlling AirPort Network Access with Time Limits

If you own an AirPort base station, you can use the Timed Access feature to control the days and times when users access the Internet. This could come in handy in a variety of situations. For example, if you own a cafe and provide free wi-fi access, you can configure the AirPort to block all access to the Internet when your business is closed. And if you have children, you can set time limits for specific devices in your home.

There are two ways to use the timed access feature. You can create a default allow policy to allow all devices to access the Internet at any time, and then specify custom schedules for specific devices. Or you can create a default deny policy to prevent all devices from accessing the Internet according the schedule you specify, and then exempt specific devices by creating custom schedules.

Here's how to control AirPort network access with time limits:

  1. Open the AirPort Utility application. (It's in Applications → Utilities.) The window shown below appears.

  2. Click the AirPort Extreme's icon. The status pop-up window appears.

  3. Click Edit. The settings window appears.

  4. Select the Network tab. The window shown below appears.

  5. Select the Enable Access Control checkbox.

  6. Click Timed Access Control. The window shown below appears.

  7. Select the Unlimited (default) option. By default, this allows all of the devices connected to your AirPort to access the Internet all day, every day, but you can change this to block Internet access for all devices (except the ones you specify later) during the times you set.

  8. If you'd like to limit the days and times that a specific device can access the Internet, click the + button under the Wireless Clients field. The window shown below appears.

  9. Enter a name for the device in the Description field.

  10. Enter the device's MAC address in the MAC Address field. You can use the following tutorials to find the device's MAC address.

  11. Use the + button under the Wireless Access Times field to create a schedule for this device's Internet access.

  12. Once you've added all of your devices and customized the schedules, click Save.

  13. Click Update. The AirPort will restart to apply the changes.

Congratulations! You have successfully set time limits for the devices connecting to your AirPort network. The schedule you created is effective immediately.

Joe wants you to Sample that: One C.R. man is on a mission to help local restaurants gain fans

When Joe Sample started posting photos of his takeout food stops in the days after Iowa restaurants were ordered shut down to dine-in service in March, he didn’t think much of it. He just wanted to get some good food while supporting restaurants.

“I have a lot of friends in the food business. My wife worked at Elevate Salon and Emil’s Deli, so she’s not working right now,” he said. “I felt it was a great way to support local businesses.”

But then a new Facebook group dedicated to promoting curbside, delivery and takeout food options in Cedar Rapids sprung up — this week, it had more than 15,000 members — and Sample started sharing photos there. The 46-year-old Cedar Rapids resident quickly found himself having a new experience — going viral.

In a pandemic, that phrase could have negative connotations, but this was the positive kind of viral spread. The kind where hundreds of people liked his photos and commented on them. Then a Cedar Rapids T-shirt maker, Ivory Pearl Designs, started selling “Be Like Joe” T-shirts and other people started showing up to order takeout in the shirts. Soon, restaurants were asking if he would come take a photo at their restaurant.

“I just started it to have fun and posted a few fun pictures, and then I started having restaurants reach out to me,” Sample said.

He decided to dedicate his stimulus check from the federal government to the effort. Sometimes, he said he hits up more than one restaurant a day.

“I’ve hit close to 60 restaurants,” he said.

He’s leaned into the enthusiasm and found ways to play up the efforts. One day he dressed as Oscar the Grouch while visiting’ Oscar’s Restaurant in Hiawatha. On another day, he and one of his daughters bought plastic pig noses to wear on a stop at the Blind Pig in Cedar Rapids. He wears a Superman costume to some stops.

“I was totally surprised at how viral it went,” he said. “Now I’m just trying to keep it exciting.”

In his day job, Sample is a salesman for American Building Components in Mount Pleasant. He normally spends a lot of time on the road, selling metal roofing, siding and steel frame structures around the Midwest. These days, he’s working from home, making sales over the phone instead. He said going out to get carryout is a chance to see other people and get out of the house.

“It brings some normalcy to my life,” he said.

He has two daughters at home, age 9 and 15, and one son, 22. When he’s not eating out, he likes to spend time outdoors with his family, fishing, camping, hunting and coaching soccer. He admits his last name is a bit on-the-nose for his newest hobby.

“A lot of people ask, ‘Is that really even your real name?’” he said with a laugh.

Sample was born and raised in Cedar Rapids, which fuels his desire to support his town.

“My dad had Sample Pharmacies when I was growing up. People helped support us, so I figured it was the least I could do, to support other local businesses,” he said. “I think the biggest thing is, we want to keep them here. There are so many great restaurants in Cedar Rapids, and we don’t want to lose half of them. I’m going to try to keep going with this until they open the places back up, as much as I can.”

He also has helped do deliveries of donated meals to area hospitals and long-term care facilities. That effort started when his younger daughter’s Girl Scout troop had dozens of boxes of unsold cookies and few options to sell them once the pandemic hit. Sample’s family purchased them and sent them to staff at Mercy Medical Center. Since then he’s dropped off boxes of pita, hummus and gyro meat from Pita’z Mediterranean and American Cuisine, trays of cinnamon rolls from Oscar’s and other places.

“People seem to be very supportive in Cedar Rapids,” he said.

He gave a lot of credit to the Cedar Rapids Facebook group, which was started by Lindsay Leahy, Brooke Murphy-Fitzgerald and Shannon Hanson. Others like it have sprung up in Marion, North Liberty and Iowa City.

“I think this has opened a lot of people’s eyes; it has given people an opportunity to try new things,” Sample said. “I’ve seen more restaurants on here than I’d ever tried before.”

He’s also started to promote nonprofits like the Freedom Festival. He is helping sell the $5 commemorative buttons — even though the 2020 festival was canceled, the buttons will help support the organization’s operations. And he helped with a Big Brothers Big Sisters fundraiser, an effort which inspired him so much he signed up as a volunteer.

He said he hopes his efforts, and others like it inspire others to support the community.

“Keep supporting local, do your best to stay healthy, and when restaurants open back up, keep going to them,” he said. “They’re going to need our help for a long time to come.”

Cargill rail yard stalls as court case rolls on

Background

CEDAR RAPIDS — After a bitter battle between residents and one of the city’s major employers — Cargill — with the city of Cedar Rapids in the middle, in December, the Cedar Rapids City Council approved a $6.5 million, 12-track, 200-car rail yard located between the Rompot neighborhood and Prairie Park Fishery.

Cargill wanted to buy and put the rail yard on a 28-acre city-owned site on Stewart Road SE. Construction required rezoning the land to industrial use and a change to the city’s future land use map — putting city officials in the spotlight.

The rail yard was needed for more supply chain stability and to protect jobs at the corn-milling plant, at 1710 16th St. SE and not far from the rail yard site, company officials said. Cargill officials planned to submit final paperwork within a month of the vote, begin construction in early spring and have the rail yard operating by the end of the year.

What has happened since?

A lot and nothing.

Before construction was to begin, the city required Cargill to provide a third-party appraisal of the land. The city had provided an initial value of $83,200, which Cargill agreed to match. However, the value of the land has been in question as nearby properties ranged from $20,000 to $30,000 an acre, which was far greater than the $3,000 per acre value the city used.

City officials say the appraisal has not been submitted, nor has Cargill sought the required permits before construction can begin.

This delay began well before disruptions from the coronavirus pandemic and after lawsuits were filed to block the rail yard.

Rompot resident and state Sen. Rob Hogg, who is a lawyer, filed two lawsuits against the City Council — one each challenging the rezoning vote and the vote to change the future land use map. Numerous neighbors and others in opposition to the rail yard have joined the lawsuit, which Hogg supported.

Meanwhile, Cargill intervened on behalf of the city. At this point, sides still are arguing whether to expand the record to include additional evidence. Dates for a hearing have not been set.

So, the status of the contentious rail yard and a timeline for construction remains in limbo.

“We don’t have anything new to share at this point regarding work and timelines specific to the development of the rail yard,” Kelly Sheehan, a spokeswoman for Cargill, said in late April.

18-year-old charged in fatal shooting arrested for drunken driving while out on bail

CEDAR RAPIDS — A 17-year-old, charged in January with fatally shooting an 18-year-old during a drug robbery, was released in March only to be arrested about a month later for drunken driving.

Kyler David Carson, now 18, of Cedar Rapids, was charged last month with operating while intoxicated and unlawful possession of an anti-anxiety prescription drug.

After two judges reduced Carson’s bail, he bonded out and was released pending trial.

Police arrested Carson April 24 when they believed he was driving under the influence of alcohol or drugs, according to a criminal complaint.

He provided a breath sample, which showed no signs on alchol, but refused to provide a urine sample for chemical testing, the complaint states.

In January, Carson was charged with voluntary manslaughter, delivery of a controlled substance-marijuana, carrying weapons and obstructing prosecution.

He is accused of fatally shooting Andrew D. Gaston, 18, on Jan. 24, as Gaston and his cousin, Tyrell J. Gaston, 16, were attempting to rob marijuana from Carson, according to a criminal complaint.

Police received a report of shots being fired at 11:48 p.m. and found Andrew and Tyrell Gaston with gunshot wounds in the parking lot of 3217 Agin Court NE.

During the investigation, police learned the Gaston cousins had arranged, with the help of others, to rob Carson that night. Witnesses told investigators they contacted Carson and “lured” him to the address to rob him of marijuana.

Carson thought he was called that night to sell 45 pre-rolled tubes of marijuana for $900, according to criminal complaint.

While Carson was delivering marijuana to the others in their car, the cousins and a third person ambushed Carson from behind, according to a criminal complaint.

Andrew Gaston struck Carson in the back of the head with a metal object. Carson then turned around and exchanged gunfire with Tyrell Gaston before running from the parking lot, witnesses told police.

Both Carson and Tyrell Gaston later discarded their firearms, which police didn’t recover, according to the complaint.

Tyrell Gaston also was charged with first-degree robbery, conspiracy to deliver a controlled substance-marijuana, carrying weapons and obstructing prosecution.

A judge, during Carson’s initial appearance in the fatal shooting, set his bail at $50,000 cash only, according to court documents. His bail was amended, in agreement with prosecutor and Carson’s lawyer, to $50,000 cash or surety March 23 by 6th Judicial Associate District Judge Russell Keast.

Carson remained in jail, but his lawyer asked for a bond review three days later, March 26, and Associate District Judge Casey Jones lowered the bail to $30,000 cash or surety.

Carson posted bail that day, according to court documents.

Assistant Linn County Attorney Rena Schulte has filed a motion to revoke Carson’s pretrial release and will request his bail ne set at $500,000. A hearing is set on the motion for next Thursday in Linn County District Court.

If convicted, Carson faces up to 19 years in the fatal shooting and up to two years for the other offenses.

Some people miss travel so much they are ordering airplane food

Imperfect Foods, an online surplus-stock grocery delivery company aimed at eliminating food waste, has begun is offering JetBlue Airline cheese and snack trays — $2.99 for three ounces of mixed cheeses, dried cherries and crackers.

Imperfect Foods CEO Philip Behn says the cheese and snack trays were an early casualty of the coronavirus pandemic.

“Almost two months ago, before it became a nationwide pandemic, this catering and airplane meal supplier said they saw a decline in economy and business-class seats,” he said. “This was one of our first COVID-19 food waste recovery opportunities. We could only take a fraction of what they had.”

Behn said his company has sold 40,000 cheese and snack trays.

“We call that ‘breaking bulk,’” Behn said. “We have stepped up with co-packers to try to repackage some of those products — it’s hard work and it’s slow, given the importance of food safety.”

Yet there are bright spots. Imperfect Foods is a budget-conscious company, so high-end products such as pineapples are usually too expensive to offer their customers.

Where do people eat pineapples? Hotels. And with hotels stalled, Imperfect Foods has been able to buy and offer them for a fair price.

It has redistributed popcorn kernels previously destined for movie theaters and broccoli florets usually reserved for restaurants. Since the beginning of March, Imperfect Foods has doubled the volume of food it was previously buying, the JetBlue snacks among many.

Julianna Bryan, communications specialist for JetBlue, said the airline has had to dramatically reduce its in-flight food and beverage service to minimize contact between customers and crew members.

“We have temporarily suspended the sales of buy-onboard products including our EatUp Snack Boxes, EatUp Café fresh food items, beer, wine and liquor,” she said.

JetBlue has donated leftover inventory of snacks to Feeding America and other food banks, as well as hospitals.

JetBlue has worked with its business partners to sell unused inventory, such as the cheese trays, at a heavily discounted price with the goal of moving it quickly and minimizing waste, Bryan said.

JetBlue is not the only airline to have to find new outlets for its in-flight overflow.

Delta has had to unload its Biscoff cookies — and it serves 80 million to 85 million of these spiced shortbread favorites each year.

At United, the Dutch stroopwafels have been piling up.

In addition to selling some of their excess, airlines have put donation programs in place. Southwest has donated more than $400,000 in snacks and other in-flight items to not-for-profit organizations and nearly 13 tractor-trailers full of groceries to 15 food banks that are a part of the Feeding America network.

Delta has donated 500,000 pounds of food around the world in the past six weeks. Front-line workers and hospitals get the Biscoff cookies along with coffee and other in-flight beverages, while other perishable food has gone to Feeding America’s partner agencies like Georgia Food & Resource Center and Missouri’s Carthage Crisis Center.

And United has donated 173,000 pounds of food to food banks and charities, pulling from airport lounges and catering kitchens. United volunteers have also processed more than 428,000 pounds of food and household goods for the Houston Food Bank.

University of Iowa aims to cut greenhouse gas emissions in half

IOWA CITY — The University of Iowa on Thursday unveiled new sustainability goals for the next decade that — if accomplished — would cut its greenhouse gas emissions in half from a decade ago and transform the campus into a “living laboratory for sustainability education and exploration.”

But the goals fall short of what a collective of Iowa City “climate strikers” have demanded for more than a year — that the UI end coal burning immediately at its power plant, commit to using only renewable energy by 2030 and unite with the city of Iowa City in a “town-gown” climate accord.

“It’s ridiculous for the UI to announce a 2030 climate plan as it continues to burn coal for years and burn methane-spewing natural gas for decades at its power plant,” said Massimo Paciotto-Biggers, 14, a student at Iowa City High and member of the Iowa City Climate Strike group.

The university’s new 2030 goals piggyback off its 2020 goals, which former UI President Sally Mason announced in 2010 in hopes of integrating sustainability into the campus’ mission.

Her goals included consuming less energy on campus in 2020 than in 2010, despite projected growth; diversifying the campus’ energy portfolio by using biomass, solar, wind and the like to achieve 40 percent renewable energy consumption by 2020; diverting 60 percent of solid waste; reducing the campus transportation carbon footprint with a 10 percent cut in per capita transportation and travel; and increasing learning and research opportunities.

The university, according to a new report made public Thursday, met or surpassed many of those goals — including, among other things, a slight dip in total energy use, despite 15 new buildings and major additions across campus.

The campus also reported 40 percent of its energy consumption comes via renewable energy sources, and it reduced annual coal consumption 75 percent.

As for waste production, the university diverted 43 percent from the landfill and reported diverting 70 percent more waste than in 2010.

2030 Plan’s first phase HAS FEWER HARD PERCENTAGES

In just the first phase, the new 2030 goals — a result of collaboration across campus involving a 2030 UI Sustainability Goal Setting Task Force — involve fewer numbers and hard percentages. Aside from the aim to cut greenhouse emissions by 50 percent compared to a 2010 baseline, the phase one goals aim to:

• Institutionalize and embed sustainability into campus culture, allowing individual units across campus to develop plans to meeting campus sustainability goals.

• Expand sustainability research, scholarship and other opportunities.

• Use the campus as a “living laboratory” capable of improving campus sustainability and ecosystems.

• Prepare students to live and work in the 21st century through sustainability education.

• Facilitate knowledge exchange among the campus community and with the state, nation, and world.

PHASE 2 EXPANDS ON GOALS

As the campus moves into phase two of its 2030 plan, it will expand on first-phase goals by identifying specific and measurable tasks and metrics.

Leadership plans to finalize that second phase later in the fall semester.

“This approach has meant including units engaged in activities such as academics, research, operations, planning, engagement, athletics, and student life,” Stratis Giannakouros, director of the Office of Sustainability and the Environment, said in a statement.

‘Ambitious and forward-looking’

Sen. Joe Bolkcom, D-Iowa City, who serves as outreach and community education director for the UI Center for Global and Regional Environmental Research, told The Gazette the new goals are “ambitious and forward-looking.”

“The new goals will engage students and research faculty to help build a sustainable path for the campus and broader community,” he said.

The university recently made big news on the utilities front by entering a $1.165 billion deal with a private French company to operate its utility system for 50 years. The deal nets the university a massive upfront lump sum it can invest and pull from annually. It gives the private operator decades of reliable income.

And the university, in making the deal, mandated its new provider pursue ambitious sustainability goals — promising to impose penalties if it failed to do so.

Nearly 25,000 more Iowans file unemployment claims

Nearly 25,000 more Iowans filed unemployment claims in the past week, Iowa Workforce Development reported Thursday.

Continuing weekly unemployment claims total 181,358, the department reported.

Iowa Workforce Development said 24,693 people filed unemployment claims between April 26 and May 2. That included 22,830 initial claims by people who work in Iowa and 1,863 claims filed by people who work in Iowa but live in another state.

State unemployment insurance benefit payments totaled $50,931,302 for the same week, the department said.

Also this week, a total of $111,378,600 in Federal Pandemic Unemployment Compensation benefits was paid to 164,088 Iowans. Since April 4, a total of $439,126,200 has been paid.

A total of $10,046,089 was paid to 15,612 Iowans receiving Pandemic Unemployment Assistance benefits.

The industries with the most claims were manufacturing, 6,053; industry not available, self-employed, independent contractors, 4,010; health care and social assistance, 2,988; accommodation and food services, 2,200; and retail trade, 1,768.

Gov. Kim Reynolds is continuing to allow more businesses to reopen, which may mean more Iowans going back to work.

On Wednesday, after meeting with President Donald Trump at the White House, Reynolds issued a proclamation permitting a variety of businesses to reopen, including dental services, drive-in movie theaters, tanning facilities and medical spas.

She also relaxed mitigation strategies in the 22 counties that remain under more strict orders because the virus is more widespread there.

Beginning Friday in those 22 counties — which include Linn, Johnson and Black Hawk — malls and retail stores may reopen provided they operate at no more than 50 percent of capacity, and fitness centers may reopen on an appointment basis only.

No Linn County Fair this year because of coronavirus concerns

CEDAR RAPIDS — The Linn County Fair has canceled grounds and grandstand entertainment at this year because of the novel coronavirus and is looking at ways youths could exhibit their work.

“After consulting with Linn County Public Health, the Linn County Board of Supervisors, and other stakeholders, it was determined this was the best decision due to the uncertainty of what the public health situation may look like at the end of June,” Albert Martin, Linn County Fair Board president, said Thursday in a statement.

The fair was scheduled June 24-28.

The Linn County Fair Association said it is working with the Iowa State University Extension and Outreach of Linn County and Linn County 4-H to determine how 4-H and FFA members and other youths will exhibit their work. Those details — which could include in-person or virtual exhibiting — are expected to be finalized and announced in mid-May.

Tom Barnes, executive director of the Association of Iowa Fairs, told The Gazette on Thursday that the Benton County Fair also was canceled for 2020.

Organizers for the Wapello County Fair in south-central Iowa previously announced they would not host the fair this year.

Ahead of VP Pence’s Iowa visit, Joe Biden’s campaign calls out ‘consequential failure’ of Trump coronavirus response

Vice President Mike Pence owes Iowans more than a photo-op when he visits Des Moines today, according to Joe Biden’s campaign.

“Iowans are seeing up close the most consequential failure of government in modern American history,” said Kate Bedingfeld, spokeswoman for the former vice president and presumptive Democratic presidential nominee.

“With nearly 300,000 Iowans filing for unemployment, rural hospitals on life support, Latino communities disproportionately suffering and workers on the job without sufficient protection, Mike Pence owes Iowans more than a photo-op — he owes them answers,” she said.

Pence, head of the White House coronavirus task force, is scheduled to meet with Iowa Gov. Kim Reynolds and U.S. Sens. Chuck Grassley and Joni Ernst, all Republicans, as well as with faith, farm and food production leaders.

Pence will talk to faith leaders about how they are using federal and state guidelines to open their houses of worship in a safe and responsible manner.

Later, he will go to Hy-Vee’s headquarters in West Des Moines for a roundtable discussion with agriculture and food supply leaders to discuss steps being taken to ensure the food supply remains secure.

Pence has called Iowa a “success story” in its response to the COVID-19, but Bedingfeld said the Trump administration failed to protect Iowa families from the virus that has claimed the lives of 231 Iowans.

“From devastating losses across the state, at meatpacking plants to rural communities, one thing is clear — it’s Iowans and the American people who are paying the price for the Trump administration’s denials and delays in response to this pandemic,” she said.

“Instead of listening to our own intelligence agencies and public health experts, Donald Trump was fed dangerous propaganda from the Chinese Communist Party — and he bought it,” she said. “Iowans deserve better — they deserve Joe Biden.”

For his part, Grassley said he welcomes the discussion with Pence.

“There’s much work to be done, and the pandemic is disrupting all of our communities,” Grassley said. “It’s important to hear directly from those who help feed the nation and the world.”

Ernst also is looking forward to the discussion of how Iowa is working to protect the health and safety of Iowa’s families and communities while reopening the state’s economy.

“We continue to take an all-hands-on-deck approach to tackling this pandemic,” she said. “Together, we will get through this.”

Now playing at Iowa county fairs: The waiting game

CEDAR RAPIDS — Getting your hands on some fried food on a stick is going to be a little more difficult this summer for Iowans.

With the COVID-19 pandemic imposing restrictions on life in the state, county fair organizers across Iowa are trying to decide if they should cancel, go virtual or wait and see if restrictions lift and their events can go on in a relatively normal manner.

One thing seems to be for certain: The fair experience won’t quite be the same this year.

“It’ll be different,” said John Harms, general manager for the Great Jones County Fair, known for attracting popular musical acts. “I can tell you that.”

Iowa is home to 106 county and district fairs, as well as the Iowa State Fair, according to the Association of Iowa Fairs. Those fairs are scheduled to begin June 17 with the Worth County Fair and continue through Sept. 20 with the conclusion of the National Cattle Congress in Black Hawk County.

Those early fairs already are beginning to announce decisions about their events. Organizers of the Wapello County Fair announced they are canceling for this year. On Thursday, the Linn County Fair Association announced it is canceling grounds and grandstand entertainment with plans to take the exhibition aspects of the fair online.

Linn County Fair Marketing Manager Heidi Steffen said the association met with county public health and Board of Supervisors officials in recent weeks. The focus of those discussions was on ensuring the safety of all fair exhibitors, workers, performers and visitors, Steffen said.

“We just couldn’t guarantee that,” she said.

Steffen was quick to point out the fair isn’t canceled — it’s just taking on a different form. The fair is scheduled for June 24-28.

The fair association is working with the Iowa State University Extension and Outreach of Linn County and Linn County 4-H to ensure 4-H and National FFA Organization members get a chance to exhibit their livestock and projects. Details on what that will look like are expected later this month.

Fair association members have been attending webinars and learning from other fairs across the country that have gone virtual. Steffen said they’ve received valuable suggestions and feedback.

“It’s been done,” she said. “We can learn from their mistakes. We can learn what went well with them and hopefully implement it here in Linn County.”

Steffen said they are already kicking around other ideas to engage the community during fair week, just in a virtual manner. Those ideas include livestreaming pie-eating contests, encouraging local businesses to offer fair foods on their menus and seeing if local artists who had been scheduled to perform at the fair would be interested in online performances instead.

“We’re open to ideas,” she said, encouraging anyone with suggestions to reach out via email or Facebook.

Up the road in Jones County, organizers there have a little more time to decide how to move forward. For now, Harms is confident that fair will go on July 22-26.

“We’re still going to have a fair,” he said. “It may look differently than what we have experienced and enjoyed in the past.”

How exactly it may look different still is up in the air. Harms said plans “a, b, c and d are all being studied.” At least one grandstand act, the Zac Brown Band, won’t be performing. But Harms said organizers have other acts they’re ready to announce “if it makes sense to have entertainment at the fair.”

Whatever takes place likely will be determined by proclamations covering social distancing made by Gov. Kim Reynolds, Harms said. He said the fair’s planning process has been dictated by her health orders.

“We’re just trying to keep everything on the table and make sensible decisions and directions based on what’s going on,” he said. “It’s going to be challenging, but I think for the most part we’ll take a deep breath, have a little more faith and we’ll get through it.”

Tim Rogers, vice president for the Johnson County Fair Board, said the decision whether to have a fair will be made in the next 40-plus days.

“That’s kind of a deadline we’ve set to either call it completely, proceed fully or proceed with what we can do and still stay in compliance with all of the laws,” he said.

The Johnson County Fair Board will discuss what a partial fair might look like once that decision has been made, Rogers said.

Tom Barnes, executive director of the Association of Iowa Fairs, said his group is providing resources to fair organizers, but is not making any recommendations on whether to proceed.

“We’re asking them to be fiscally responsible for their fair,” he said. “We don’t ask them to cancel. We don’t ask them to go ahead with their fair. They know better what they can do and not do.”

Barnes said fair organizers should be asking themselves: If your fair is open, will people buy tickets? And, if they come, will they buy food and beverages?

As long as they make good financial decisions, Barnes said, he believes county fairs have the resources to weather the COVID-19 storm and return in 2021.

“We’ll be back next year if the fairs don’t go ahead,” he said.

TrailBuddy: Using AI to Create a Predictive Trail Conditions App

Viget is full of outdoor enthusiasts and, of course, technologists. For this year's Pointless Weekend, we brought these passions together to build TrailBuddy. This app aims to solve that eternal question: Is my favorite trail dry so I can go hike/run/ride?

While getting muddy might rekindle fond childhood memories for some, exposing your gear to the elements isn’t great – it’s bad for your equipment and can cause long-term, and potentially expensive, damage to the trail.

There are some trail apps out there but we wanted one that would focus on current conditions. Currently, our favorites trail apps, like mtbproject.com, trailrunproject.com, and hikingproject.com -- all owned by REI, rely on user-reported conditions. While this can be effective, the reports are frequently unreliable, as condition reports can become outdated in just a few days.

Our goal was to solve this problem by building an app that brought together location, soil type, and weather history data to create on-demand condition predictions for any trail in the US.

We built an initial version of TrailBuddy by tapping into several readily-available APIs, then running the combined data through a machine learning algorithm. (Oh, and also by bringing together a bunch of smart and motivated people and combining them with pizza and some of the magic that is our Pointless Weekends. We'll share the other Pointless Project, Scurry, with you soon.)

The quest for data.

We knew from the start this app would require data from a number of sources. As previously mentioned, we used REI’s APIs (i.e. https://www.hikingproject.com/data) as the source for basic trail information. We used the trails’ latitude and longitude coordinates as well as its elevation to query weather and soil type. We also found data points such as a trail’s total distance to be relevant to our app users and decided to include that on the front-end, too. Since we wanted to go beyond relying solely on user-reported metrics, which is how REI’s current MTB project works, we came up with a list of factors that could affect the trail for that day.

First on that list was weather.

We not only considered the impacts of the current forecast, but we also looked at the previous day’s forecast. For example, it’s safe to assume that if it’s currently raining or had been raining over the last several days, it would likely lead to muddy and unfavorable conditions for that trail. We utilized the DarkSky API (https://darksky.net/dev) to get the weather forecasts for that day, as well as the records for previous days. This included expected information, like temperature and precipitation chance. It also included some interesting data points that we realized may be factors, like precipitation intensity, cloud cover, and UV index. 

But weather alone can’t predict how muddy or dry a trail will be. To determine that for sure, we also wanted to use soil data to help predict how well a trail’s unique soil composition recovers after precipitation. Similar amounts of rain on trails of very different soil types could lead to vastly different trail conditions. A more clay-based soil would hold water much longer, and therefore be much more unfavorable, than loamy soil. Finding a reliable source for soil type and soil drainage proved incredibly difficult. After many hours, we finally found a source through the USDA that we could use. As a side note—the USDA keeps track of lots of data points on soil information that’s actually pretty interesting! We can’t say we’re soil experts but, we felt like we got pretty close.

We used Whimsical to build our initial wireframes.

Putting our design hats on.

From the very first pitch for this app, TrailBuddy’s main differentiator to peer trail resources is its ability to surface real-time information, reliably, and simply. For as complicated as the technology needed to collect and interpret information, the front-end app design needed to be clean and unencumbered.

We thought about how users would naturally look for information when setting out to find a trail and what factors they’d think about when doing so. We posed questions like:

  • How easy or difficult of a trail are they looking for?
  • How long is this trail?
  • What does the trail look like?
  • How far away is the trail in relation to my location?
  • For what activity am I needing a trail for?
  • Is this a trail I’d want to come back to in the future?

By putting ourselves in our users’ shoes we quickly identified key features TrailBuddy needed to have to be relevant and useful. First, we needed filtering, so users could filter between difficulty and distance to narrow down their results to fit the activity level. Next, we needed a way to look up trails by activity type—mountain biking, hiking, and running are all types of activities REI’s MTB API tracks already so those made sense as a starting point. And lastly, we needed a way for the app to find trails based on your location; or at the very least the ability to find a trail within a certain distance of your current location.

We used Figma to design, prototype, and gather feedback on TrailBuddy.

Using machine learning to predict trail conditions.

As stated earlier, none of us are actual soil or data scientists. So, in order to achieve the real-time conditions reporting TrailBuddy promised, we’d decided to leverage machine learning to make predictions for us. Digging into the utility of machine learning was a first for all of us on this team. Luckily, there was an excellent tutorial that laid out the basics of building an ML model in Python. Provided a CSV file with inputs in the left columns, and the desired output on the right, the script we generated was able to test out multiple different model strategies, and output the effectiveness of each in predicting results, shown below.

We assembled all of the historical weather and soil data we could find for a given latitude/longitude coordinate, compiled a 1000 * 100 sized CSV, ran it through the Python evaluator, and found that the CART and SVM models consistently outranked the others in terms of predicting trail status. In other words, we found a working model for which to run our data through and get (hopefully) reliable predictions from. The next step was to figure out which data fields were actually critical in predicting the trail status. The more we could refine our data set, the faster and smarter our predictive model could become.

We pulled in some Ruby code to take the original (and quite massive) CSV, and output smaller versions to test with. Now again, we’re no data scientists here but, we were able to cull out a good majority of the data and still get a model that performed at 95% accuracy.

With our trained model in hand, we could serialize that to into a model.pkl file (pkl stands for “pickle”, as in we’ve “pickled” the model), move that file into our Rails app along with it a python script to deserialize it, pass in a dynamic set of data, and generate real-time predictions. At the end of the day, our model has a propensity to predict fantastic trail conditions (about 99% of the time in fact…). Just one of those optimistic machine learning models we guess.

Where we go from here.

It was clear that after two days, our team still wanted to do more. As a first refinement, we’d love to work more with our data set and ML model. Something that was quite surprising during the weekend was that we found we could remove all but two days worth of weather data, and all of the soil data we worked so hard to dig up, and still hit 95% accuracy. Which … doesn’t make a ton of sense. Perhaps the data we chose to predict trail conditions just isn’t a great empirical predictor of trail status. While these are questions too big to solve in just a single weekend, we'd love to spend more time digging into this in a future iteration.
