What's Up UA? - Close Encounter 'One in a Million'

Faster than a speeding bullet comes the comet Siding Spring, which will have the attention of UA scientists as it passes Mars on Oct. 19.

University of Arizona scientists have their eyes on Mars for the fly-by of comet Siding Spring, which will pass the red planet on Oct. 19, closer than any comet has ever zoomed past the Earth in recorded history.

"We expect Mars to be bathed in the comet's coma, the gas and dust clouds that make for their famous tails," said Roger Yelle, a professor of planetary science in the UA's Lunar and Planetary Laboratory, who is on the science team of NASA's MAVEN spacecraft, which went into orbit at Mars on Sept. 21.

"The probability of an encounter like this is one in a million."

MAVEN — short for NASA's Mars Atmosphere and Volatile Evolution mission — is the latest addition to an armada of seven spacecraft currently studying Mars, either observing from high above or roving and digging on the surface.

During the comet fly-by, NASA has programmed its orbiters to take measurements and images, then "duck and cover" behind the planet, just in case.

"It only takes a half-a-millimeter-size particle traveling at 56 kilometers per second to injure one of these spacecraft," said Don Yeomans, manager of NASA'sNear Earth Object Program Office.

Yelle and his colleagues anxiously await the arrival of the city-block-size chunk of ice, rock and dust on its first-ever journey toward the sun. Unlike so-called short period comets whose journey around the sun takes them into the inner parts of the solar system every few years or decades, Siding Spring is a long period comet, visiting the solar system for the first time from the far reaches of space.

The comet originated in the Oort Cloud, a vast region of space surrounding the solar system speckled with billions of far-and-few-between comets, some of which embark on journeys that bring them back into our system of planets from which they originated billions of years ago during the early evolution of the solar system.

"Those comets are especially interesting because they are pristine," Yelle explained. "Comets are leftovers from the birth of the solar system, but unlike short-period comets, which have been altered by the sun's heat and solar wind, Siding Spring has been in deep freeze, in deep space, for billions of years."

Alfred McEwen, a professor in the UA Department of Planetary Sciences, leads the High Resolution Imaging Science Experiment, known as HiRISE, on NASA's Mars Reconnaissance Orbiter, or MRO.

"This is the first time the nucleus of a long-period comet can actually be resolved by a telescope, either in space or on the ground," McEwen said. "Planning a spacecraft mission to these types of comets is nearly impossible because there is typically only about a year's notice between discovery and passage into the inner solar system."

Because comets such as Siding Spring are difficult to study, scientists know very little about them.

"We want to know the shape of its nucleus, rotation period, its brightness, and hopefully observe the inner coma for jets and outbursts," McEwen said.

All previously resolved comet nuclei are nearly black on their surfaces, despite being rich in ices. A key unanswered question is whether comets are formed black, become black from exposure to galactic cosmic rays, or are blackened over frequent visits to the inner solar system.

In hopes of lifting some of Siding Spring's secrets, the UA-led HiRISE camera team will interrupt its daily routine of photographing the Martian surface.

"We will roll the spacecraft and point HiRISE at the approaching comet," McEwen said. "The tricky part is to predict where the camera has to look, because the comet will be close and traveling fast. Photographing the comet's nucleus at its closest approach is like trying to photograph a speeding bullet while riding a roller coaster."

"Over the past month the comet has been observed to fade in brightness compared to standard comet models, but we should still get a good look at the nucleus even if the coma is not very active."

Comet Siding Spring first appeared on images taken by the UA's Catalina Sky Survey but was not identified as an Oort Cloud comet until independent discovery observations were made approximately four weeks later, by Robert McNaught at the Siding Spring Survey. The survey was one of three telescopes operated by CSS — and the only full-time asteroid survey in the Southern Hemisphere.

On Oct. 19, Siding Spring will race past Mars within 88,000 miles, less than a third of the Earth-moon distance, closer than any comet has ever passed the Earth in recorded history. Traveling at 35 miles per second, the comet — less than half a mile in diameter — would shoot over Los Angeles and out into the Pacific Ocean only one minute after it appeared over Manhattan.

Siding Spring will never get close to the Earth, Yelle said.

"After its pass by the orbit of Mars, it will go back to the Oort Cloud and not come back for many millions of years, if ever," he said.

Scientists are not sure of what to expect when Siding Spring zooms by Mars. What is certain, though, is that there is no chance of an impact.

"Earlier on, there was some concern the dust trail could endanger the spacecraft, but that no longer seem to be a possibility," Yelle said. "Nevertheless, we are taking mitigation strategies to be cautious. When the comet is coming, we'll be hiding on the other side of Mars, and when it goes by, we'll turn the MAVEN spacecraft so that the least sensitive surfaces are pointing to the comet and can't damage instruments.

"After about an hour, we'll come out of hiding. MAVEN will be observing the comet for about three days before and two days after the fly-by."

In contrast, MRO will observe the comet during its closest pass to Mars, although the orbiter will be hiding behind Mars when the dust trail will pass, if it extends that far. 

Over eons, Mars has been losing its atmosphere to space, and MAVEN is a mission designed to study the physical and chemical aspects of that process.

"The atmosphere escape process happens from the upper parts of the atmosphere, close to the region that will be perturbed by the coma of the comet, mostly by water molecules," Yelle said. "They will hit the Martian atmosphere about 250 kilometers above the surface and heat it through their impact momentum, which will in turn tell us about the escape process. We will also study the comet itself — for example, ions that stream from its coma."

What's Up UA? - Austin Hill: The Comeback Kid

If you were to look at the Arizona football record books in the receiving category, you would see senior Austin Hill’s name all in almost every category. In just two and a half years, he has the seventh-most receiving yards in a career (1,983 yards), the fifth-most receptions in a season (81 in 2012), the third-most receiving yards in a season (1,364 in 2012), tied for the most touchdowns in a season (11 in 2012), tied for eighth in career receiving touchdowns (16), tied for the third-most receptions in a single game (11 against Stanford in 2012), has the highest average gain per reception with a minimum of 10 receptions in a game (25.9 yards against USC in 2012) and has the second-most receiving yards in a game (259 against USC in 2012).

It is safe to say that Hill is one of the best receivers to ever put on an Arizona uniform. In his freshman season, he played in 10 games while starting one. He caught 21 passes for 311 yards and two touchdowns. Hill blew up his sophomore year catching 81 passes for 1,364 yards and 11 touchdowns. He also averaged 104.9 yards per game and 16.8 yards per catch. He finished that year as a semifinalist for the Biletnikoff Award, given to the best wide receiver in the country.

Hill was poised to become a top receiver in the game his junior year, until he tore his ACL in spring practice. 

“I thought that I had lost everything,” Hill said. “I didn’t know what to do or how to react to the situation. I took a day where I didn’t really talk to anyone.”

Hill immediately began his rehab so he could get to full strength as fast as possible. For anyone who has ever torn their ACL, coming back from that injury is a long, grueling process that takes a lot of patience and hard work. 

“The rehab process was rough because it was the same thing every day for a couple months at a time,” Hill said. “Some days you had to take off to get rest, but I would feel good so I didn’t really want to. Then there were some days where I had to rehab and I felt horrible and I couldn’t take a break. It’s frustrating to be an athlete and then have to become non-athletic and learn to do everything again on one leg. It’s hard, physically and mentally.”

The strength staff Arizona is known as one of the best in the country. Strength coaches Chris Allen and Parker Whiteman pushed Hill to his limits to make sure that when he did come back, he would be better than he was before he got hurt.

“The strength staff, especially Parker (Whiteman) and Chris (Allen), really helped me,” Hill said. “I wouldn’t have been able to do it without the strength and medical staffs at my side every day. I was able to really feel that they had my back and they would help me. They pushed me past my limit, and I think that helped me a lot.”

Hill’s fellow receivers DaVonte’ Neal and Cayleb Jones also made the rehab process easier on him. Neal and Jones redshirted the season per transfer rules.

“I always had a lot of time to talk to them on the sideline,” Hill said. “I was able to watch games and see what we were doing and I was able to become good friends with them because we had a lot more time to talk.”

As the year went on, Hill became more motivated every day. He wanted to play right away, but he knew he was a long way away, and that was his motivation.

“Every day was motivation for me,” Hill said. “I got a little more upset every day, especially the days I wasn’t able to rehab. It motivated me because I didn’t want to feel this way anymore and I wanted to get to 100 percent as fast as possible.”

He wanted to play in the AdvoCare V100 Bowl, so Hill was constantly being pushed by everyone to work as hard as he could and to never give in to the pain and frustration. The thought of giving up never crossed his mind because nobody would allow that.

“My goal was to be able to play in the bowl game,” Hill said. “If I wasn’t able to do that, I wanted to run out of the tunnel with the team. Neither of those were able to happen, but I never gave up on myself and neither did anyone else. Even if I wanted to give up, it would’ve been rough for me.”

After the 2013 season ended, Hill had a choice. He could enter the NFL Draft and have a very good chance at being selected, or return for his senior season and finish what he started. He decided to come back, and seems content with his decision.

When spring practice began in 2014, Hill began to participate more than he ever did. He was able to practice with the team and play in the spring game.

“It was during the spring when I felt that I was back,” Hill said. “I was running routes and everything was clicking. Even though I played with my brace on, that was the first time I felt like I was back. When my brace came off is when I felt that I was almost where I wanted to be and I was getting comfortable with my knee.”

Finally, fall practice began, and Hill was more than excited to start. Normally, players aren’t thrilled about having to go through fall camp, but Hill was just happy to be there because he wasn’t able to participate the year before.

“It felt good to be back with the team,” Hill said. “I don’t think anyone loves camp, but I had love for it for the first couple of days. I missed it because last year I had to watch everyone. I was happy because I could finally be with everyone again and run around with them instead of standing on the sideline.”

It is hard not to think about, but Hill tries to focus on the present and the future instead of thinking about how far he has come in the last year and a half.

“I try not to think about the past,” Hill said. “I try to stay in the present and think about what I can do in the future. When I get down on myself or something isn’t happening the way I want it to, my parents will remind me that last year you couldn’t even walk and that I should be happy that I can play because a lot of people aren’t able to come back from this injury.”

So far, Hill has picked up right where he left off. Through four games, he has 15 catches for 263 yards and three touchdowns. He is averaging 17.5 yards per catch, the highest of his career so far.

“Austin is a really smart guy,” head coach Rich Rodriguez said. “I know this year is really important to him because he wants to finish off his career right. He has great ball skills, but better than anything he has a great feel for the game.”

The senior has high hopes for his last year as a Wildcat as he wants play in a Rose Bowl and possibly farther.

“I want the team to be the best we can be,” Hill said. “I want to do anything that will help, even if that’s better blocking, and I don’t always have to catch the ball. My biggest goal is to do the best I can for the team and get us to a Rose Bowl.”

Hill has worked extremely hard for the past year and a half to get to this point.

“It’s definitely been worth it for me,” Hill said. “Being able to put on pads and run around with my teammates has made it worth it. It reminds me that I’m lucky to have been able to come back. As far as I can tell, I am moving in the right direction.”

What's Up UA? - Ready for a Super-Fast Internet? UA Scientists Are Fast at Work on It

Removing barriers along the way to a blazingly fast Internet is the declared goal of scientists at the University of Arizona College of Optical Sciences who are leading an international consortium tasked with developing new technology to make it happen.

In 2008, the National Science Foundation gave a five-year, $18.5 million grant to establish an engineering research center (ERC) that is based at the UA and united with other universities in a collaboration known as the Center for Integrated Access Networks, or CIAN.

The NSF recently approved funding for the second half of the project, totaling about $17 million, more than half of which goes to the ERC at the UA. Each year, the center also receives roughly $2 million in support from corporate sponsors and an additional $1 million from other agencies.

"Our goal with CIAN is to remove the bottleneck of the Internet so the entire network becomes more scalable," said Nasser Peyghambarian, director of the ERC and professor in the College of Optical Sciences. "In other words, more users can access it at higher speed, lower cost and lower energy consumption."

As the number increases of end users accessing the Internet with computers and mobile devices, the network has to grow, become faster or both.

"It's not going to expand indefinitely, so we have to create new technologies to be able to handle that growing demand," Peyghambarian said. 

The key to accomplishing that goal lies in developing a hybrid architecture that marries electronics and optics, and that is exactly what Peyghambarian and his colleagues are working on at the ERC.

"As an end user right now, you have to rely on electronics for the information you are trying to send or receive through the Internet," Peyghambarian explained. "Your computer and smartphone are electronic devices. They send electronic signals into the data superhighways of the Internet, and those have always been fiber-optic networks. But the optical signals are being transformed back into electronic signals at the receiving ends. The goal of CIAN is to bring optics closer and closer to the end user."

"People want more information going to their homes," added Daniel Kilper, a research professor of optical sciences and CIAN's administrative director. "Tomorrow's Internet no longer is about the information superhighway, it's more about information Main Street or information neighborhood — fiber-optics all the way to the home."

To achieve that new kind of capability and bandwidth going to individual users, scientists and engineers have to reduce the cost and energy consumption of the photo-electronic components. One of the key technologies developed by CIAN involves arrays of miniaturized mirrors to control laser pulses that in turn modulate high-speed electronic signals, a process known as optical circuit switching.

"We develop new photonic integrated circuits using a technology called silicon photonics," Kilper said. "We can take all these bulky optical components here and put them onto a chip, and then we can start to integrate that optical chip with the electronic chip, either side by side or even potentially on the same chip to gain efficiency, reduced cost and reduced power consumption so that these devices can be mass-produced and go out to individual users.

"With today's commercially available systems you can already achieve transmission rates of 400 gigabits per second, but we're looking at a terabit and beyond," Kilper said.

The research at CIAN has garnered much industry interest, attracting 20 industry affiliates ranging from hot startups such as Calient and Bandwidth10 to industry heavyweights including Fujitsu, Texas Instruments, Intel and Samsung.

CIAN doesn't focus on the research alone but plays an important role in education at several levels. Graduate students have gone on to apply their expertise in companies working on making the faster Internet a reality. Some have founded their own companies specializing in integrated optical-electronic circuits; others have embarked on careers at other universities.

In educating students, CIAN follows the guidelines of Engineer of 2020, an initiative spearheaded by the National Academy of Engineering to equip engineering graduates with the skills and knowledge they need to succeed in emerging and future markets.

"Future graduates need to have new capabilities that go beyond engineering," Peyghambarian said. "They need to be entrepreneurs, and they have to come up with new ideas, so we train our students and put them in workshops to become entrepreneurs of the future."

In addition to its core funding, CIAN has attracted renewed and additional funding for two three-year programs bringing research experience to undergraduates (REUand teachers(RET), with a special emphasis on minorities and underserved communities including Native Americans, Hispanics and African-Americans.

"We have been engaged in outreach to Indian reservations, where education and outreach have been received really well," Peyghambarian said. "In addition, we have a program for veteran education, funded by NSF specifically for that purpose."

"CIAN illustrates the remarkable diversity of optics and photonics applications pursued by the College of Optical Sciences," said Dean Thomas Koch. "Our college has a culture of being able to successfully meld basic research, teaching and service to industry, allowing us to offer an unparalleled educational experience for our students. Our faculty and students constantly push the boundaries of what's possible through discovery and innovations, with breakthroughs in the applications of light that impact virtually every field of science and industry."

UA's national partners in CIAN are the University of California San Diego; the University of California Los Angeles; the University of Southern California; California Institute of Technology, the University of California Berkeley; Columbia University and Cornell University in New York; Norfolk State University in Virginia; and Tuskegee University in Alabama. International partners are Aalto University in Helsinki, the University of Eastern Finland, the University of Darmstadt in Germany and the Korea Advanced Institute of Science and Technology in Daejeon, South Korea.

What's Up UA? - Using the Force: UA Police Officer Completes NASA Project

University of Arizona Police Officer Andrew Lincowski joined planetary scientists at NASA this summer to search for exoplanets that might have the potential to harbor life.

 
Haystacks uses high-fidelity spatial and spectral models of planetary systems to help astronomers search for earth-like planets in our galaxy. This model, which Lincowski helped develop, shows our solar system in a head-on view.
 

One night on patrol at the Posada San Pedro residence hall on the University of Arizona campus, UA Police Officer Andrew Lincowskifound himself stopping to help a student in need. This was not the kind of aid that police officers normally perform: Lincowski was summoned to assist with physics homework.

If this seems unusual for an on-duty officer, that's because it is. Lincowski is also an undergraduate student at the UA studying physics and astronomy, and recently he completed a summer-long internship at NASA.

The possibility of finding life-sustaining planets beyond our solar system has long captured the public's imagination, and the search is intensifying among today's top scientists. This past summer, Lincowski joined leading scientific minds at NASA's Goddard Space Flight Centerin the investigation.

Lincowski traveled to Greenbelt, Maryland, over the summer as a NASA intern. Out of several hundred participants in the internship program, Lincowski was one of only 16 nationwide recipients of the prestigiousJohn Mather Nobel Scholarship, offered by the National Space Grant Foundation. During his stay, he participated in a project affectionately called "Finding the Needles in the Haystacks," otherwise known as theHaystacks Project.

"Haystacks is all about searching for Earth-like, extrasolar planets," says Lincowski. "This work is enabling us to determine what else is out there."

The existence of extrasolar planets, or exoplanets, wasn't confirmed until 1988. Since then, more than 1,800 exoplanets have been discovered. The goal of Haystacks is to create high-fidelity models of extrasolar planetary systems to help scientists identify exoplanets and investigate them for signs of life.

"These models will be the inputs for detailed simulations of exoplanet observations with future NASA missions, including ones capable of finding truly Earth-like planets," explains NASA scientist Aki Roberge, principal investigator on the Haystacks Project and a mentor to Lincowski.

Spotting the dim light that corresponds to a far-away exoplanet is a colossal undertaking. One of the most effective ways to determine what an Earth-like planet might look like is to study the properties of our own solar system. Lincowski's role in the Haystacks Project was to create a model of how our solar system would appear if observed from far away.

Lincowski's efforts on Haystacks will inform the development of the Advanced Technology Large-Aperture Space Telescope, a NASA flagship mission planned for launch between 2025 and 2035. ATLAST will scan the stars for signs of life beyond our own solar system, and provide scientists with new insights into the underlying physics governing our universe.

"Andrew did an amazing job on the project this summer, showing great independence and persistence," Roberge says. "I think Andrew is a born scientist. He combines intelligence and discipline with valuable skills in writing and communication."

When he's not preoccupied unraveling the mysteries of the cosmos, Lincowski can be found in uniform, serving protecting his fellow students as an officer in the UA Police Department.

After Lincowski graduated with an accounting degree from the UA in 2006, he began working for a homebuilder. When the housing market crashed, he decided that he'd had enough of accounting and joined the Tucson Police Department. He hopes to one day work for the FBI and investigate financial crimes.

Ultimately, his interest in mathematics and the origins of the universe led him back to the UA in 2011 to begin his studies in physics and astronomy. In the spring of 2012, he transferred from TPD to UAPD.

"I loved it," Lincowski says. "UAPD is different than city or town agencies — they truly partner with the community."

Since then, he has managed to juggle a full academic course load and a demanding career as a campus police officer. He says the role of UAPD is far more diverse than people might realize.

"It's important to educate students and faculty about law and safety," says Lincowski, who also serves as a UAPD liaison to the Posada San Pedro residence hall. "We spend a lot of time on public outreach, and teaching people how to prepare for and deal with emergencies."

Brian Seastone, chief of police at UAPD, calls the department's commitment to community-oriented policing "total engagement."

"At the University, you can go from responding to a fire alarm to talking to a Nobel laureate — it's an incredible place to work," Seastone says. "We don't want officers just going out there and patrolling, we want them getting involved in the campus community.

"We are very fortunate that we have not only Andrew but a number of officers and civilian employees that are going to school, so they can see the student side of campus life and bring it back to UAPD. It makes us a better department."

When considering a drastic career change, Lincowski said it was important to be well rounded, have a financial plan, and be mentally and physically prepared to make the transition.

"You have to jump in with both feet, and be prepared for the long haul," he says. "You can't slack."

After the completion of his studies, Lincowski hopes to attend graduate school and complete a Ph.D. in astrophysics. He'd like to study high-energy physics, the origins of the universe, and the fundamental nature of matter and energy.

"Physics and astronomy are relatively far removed from the normal perception of most people, but everyone's technology is based on physics," Lincowski says. "We are at a point where computing technology is not going to progress much further without understanding and employing quantum mechanics. Advanced physics is required to continue to develop technology, even in biology and medicine."

Lincowski hopes that his efforts will help the public understand the importance of STEM education and increase awareness of scientific advancements.

"They say that civilizations are measured by their art and science," he says. "These things increase the quality of our lives, and move us forward as a species."

What's Up UA? - How New Social Movements Take Root

Contemporary movements, such as those initiated after the recent shooting death of Michael Brown in Ferguson, Missouri, can be born seemingly overnight in the digital age. UA researchers point to several factors.

UA sociologist Jennifer Earl has been investigating policing policies, and the relationship between protesters and the police, dating back to the 1960s.
 
After the shooting death of Michael Brown in Ferguson, Missouri, #BlackLifeMatters — first used after the shooting death of Trayvon Martin — re-emerged in popular media and social media platforms, reigniting national conversations about policing practices, particularly in African-American communities.

Much like campaigns such as #YesAllWomen, #OccupyWallStreet, #BringBackOurGirls and #AllMenCan, the handle also has been used to animate community-based action, political debate and state agency response. The same can be said of #BlackLivesMatter, which has led to the organization of initiatives and protests similar to those of the Freedom Riders in the 1960s.

At a minimum, such campaigns have helped to get people talking about societal ills. In some cases, they have led to social reforms and policy shifts, suggesting that the role of technology and social media is revolutionizing contemporary movements, said Susan Shaw, an associate professor in the UA School of Anthropology.

Such initiatives indicate major changes in the ways that social movements form and evolve, said Shaw, who is among UA social scientists working to advance understanding about new movements.

UA sociologist Monica Casper, head of the UA's Department of Gender and Women's Studies, is teaching an honors course this semester on racial inequality and social justice in the wake of #BlackLifeMatters and the Ferguson case. Casper also has helped organize several campus events leading up to the "Black Life Matters Conference" to be held at the UA in January.

"There were several aspects of the Ferguson case that outraged people, including the fact that white police shot an unarmed black teenager and left his body in the street for hours. There was no apology, no accountability," Casper said.

"In the U.S., we are not even close to being 'post-racial,' and white supremacy runs deep in our institutions, histories, cultural memory and pop culture," Casper said of the need to understand activism represented by #BlackLifeMatters.

The birth of social movements

Casper, Shaw and other social scientists at the UA note at least three significant phenomena associated with new social movements:

  • Single-issue movements appear to be in decline, with evidence for unification around cross-issue organizing. 
  • Many new movements appear to launch after multiple grievances — especially in various parts of the nation —become evident in the larger public sphere.
  • The use of technology is aiding movement development, growth and sustainability.

For example, #BlackLifeMatters began in a smaller social circle. It is not only tied to cases sharing similar consequences — the shooting deaths of Kimani Gray in New York, Renisha McBride in Michigan and Martin in Florida — but it also evoked issues related to law enforcement policies, policing practices, black popular culture, media representation and the betterment of the African-American community.

"Brown's death, layered on top of the earlier tragedies, generated a national conversation, an outpouring of grief and a movement," Casper said.

Two schools of thought exist on how social movements are born and sustained. One holds that people organize around grievances. The other holds that grievances require a "political opportunity," an availability of resources necessary for organizing: time, money, space and access to media representatives.

Above all, social movements usually are established around issues of political and social equity, Casper said.

"Social movements are typically born out of some deep, shared concern and need to make change, and while they are often organized on behalf of social justice, they may also congeal around shared values, as in the anti-abortion movement," Casper said. "They often attract people who may be marginalized vis-à-vis the dominant society or group."

Shaw and Casper noted that a significant boon to launching new social movements has come through technology, specifically social media platforms with their immediacy and massive international networks.

"Movements need direction, communication, and shared vision — something that has become quite easy to provide in our digital age, where social media has both ignited and enabled various movements," Casper said.

The Arab Spring protests that began at the end of 2010 are a significant example, having taken the international stage sparked by social media. In fact, social media interactions, especially those on Facebook, are credited with regime changes in the Arab world, Shaw said.

"With social media platforms, people can communicate outside of official challenges that are not monitored and, of course, have the capacity to reach mass audiences," Shaw said. "It also helps people who are facing stiff government resistance to find a way to communicate, gather and organize."

National shifts in policing practices

The period spanning the 1960s and '80s resulted in significant changes in policing policies related to protests, said Jennifer Earl, a UA sociology professor and an expert on social movements and movement repression.

Earl, recently funded with a National Science Foundation grant to study U.S. policing practices dating back to the '60s, said the '70s marked a move in policing from a repression model to a "negotiated management" approach.

The negotiation approach, the prevailing model by the late '70s, is designed to reduce force and decrease protest intensity, Earl said. Agencies have done this by implementing permit requirements and negotiating with protesters about the time, place and manner of protest, she said.

Since the '90s, however, the nation has seen a rise in "police militarization," a move to arm officers with tactics and weapons normally reserved for warfare. The negotiated management model has been irregularly implemented, Earl said.

"You can see, in situations like Ferguson, that even when you have models of practice that departments and chiefs of police agree on, that doesn't mean they are always implemented," she said. "So, in Ferguson, it was like watching different scripts for police action from the 1960s to the mid-1970s play out in fast forward."

The public response since Brown's death has aligned with what Casper and Shaw noted about new social movements.

"Ferguson did create some real public awareness about police militarization, and this is causing some pushback," Earl said. "Now some cities are saying, 'We don't want and we don't need these tools in our communities.' But where it will settle is hard to tell."

The country has not seen such a significant change in police policies since the '80s, Earl said, adding that post-9/11 concerns have had an effect.

"There are a lot of competing models for how police should handle protests, but a singular model that enjoys wide consistence in the law enforcement field? We are not there yet," Earl said. "We are still in that innovation process, and the best practices have not yet emerged. Police are still struggling with their responsibility to protect and also support protesters' rights."

Evidence of a change in organizing and action had been present for a while. 

"It was in the late 1990s with the World Trade Organization protests in Seattle that we began to see all manners of concerns addressed — labor, environment, class issues, anti-poverty," Shaw said.

"That was the first time we saw that, and I suspect we will see more of that as people become increasingly aware that many issues are interconnected and simultaneously demand attention to multiple points of view."

What's Up UA? - UA Paves Way to Redefine STEM Education

The University of Arizona is helping to enhance science, technology, engineering and mathematics education, as one of just eight sites in the United States chosen to participate in a major national STEM education initiative.

In June 2013, the Association of American Universities announced that the UA and seven other project sites would receive grant funding through the AAU Undergraduate STEM Education Initiative, which was established to address a nationwide demand to improve STEM education and to retain more majors and expand the workforce in STEM fields.

Since then, the UA has made important progress with course redesigns and faculty programs intended to make STEM teaching and learning more engaging. 

"We need more STEM majors," said Gail Burd, UA senior vice provost for academic affairs and a principal investigator on the UA's AAU grant. "A lot of evidence points to a loss of students from STEM majors because of the way they're being taught. These are hard subjects, and if it's not engaging and it's hard, students drift away."

Under the AAU Undergraduate STEM Education Initiative, which is funded by The Leona M. and Harry B. Helmsley Charitable Trust, the UA established the UA-AAU Undergraduate STEM Education Project — a comprehensive, interdisciplinary effort intended to expand STEM-related collaborations, curricula and funding opportunities.

Funded through 2016, the UA-AAU STEM Project saw a number of successes in its first year.

Course redesigns promote active learning

Under the leadership of John Pollard, the UA's director of general chemistry, andVicente A. Talanquer, a chemistry and biochemistry professor, a foundational UA chemistry course has been restructured to more actively engage students.

The redesigned  "Chemical Thinking" course, in development for three years, debuted this fall to more than 2,400 students in general chemistry, course 151. It incorporates more group-based discussions, problem-solving activities and other forms of active engagement, with less than 10 minutes of the hourlong class devoted to traditional lecture.

Students in an earlier pilot of the course reported better information retention and overall satisfaction with the redesigned course compared to traditional chemistry classes. This fall, four additional instructors are teaching general chemistry using the revamped curriculum for the first time.

"We are working to understand challenges and successes these new faculty might have to implementing the new curriculum with more active and engaged instructional approaches," Burd said.

Modeled after the chemistry course's success, a similar redesign is being introduced in a foundational UA biology class this semester. Meanwhile, the University's introductory course in computer programming for engineering applications has been restructured to include lab time and to emphasize student participation.

New instructional approaches also were introduced in a pilot general physics course last spring, with students reporting positive results in learning outcomes. A redesign also is in the works for the UA's introductory chemical engineering course.

Learning communities, workshops encourage teaching differently

As part of the effort to make STEM classes more engaging, the University has launched professional development opportunities intended to get instructors to think about teaching in new ways.

About 30 STEM faculty members participated in Faculty Learning Communities last year, in which they were tasked to come up with two weeklong engagement activities to teach in their classrooms each semester.

The University also launched a series of "Teaching Talks" and a three-hour workshop, specifically geared toward STEM educators on campus.

"The goal is to stretch beyond those five redesigned introductory courses and change the culture around the way we're teaching all STEM courses," Burd said.

Additional workshops and talks will take place in the coming year, including a daylong workshop with an architect and an expert on learning spaces that will look at how faculty can make the best use of physical spaces to make them more engaging. 

As part of that workshop, Pollard will spend a week or two teaching in a nontraditional space — a redesigned journal reading room in the Science and Engineering Library.

As the UA continues to forge new territory in STEM education, it is carefully tracking and analyzing its efforts to determine their effectiveness. Postdoctoral student Jonathan Coxis helping to lead that ongoing assessment, beginning with the redesigned general chemistry course, Burd said.  Jane Hunter, an associate professor of practice in the UA's Office of Instruction and Assessment, also has joined the AAU project to provide project support and management. 

Other goals for the UA-AAU Undergraduate STEM Education Project, Burd said, include establishing a teaching symposium and developing and expanding teaching awards that recognize and financially reward outstanding STEM educators on campus.

In addition to Burd, the UA-AAU Undergraduate STEM Education Project leaders include co-principal investigators Deb Tomanek, associate vice provost for instruction and assessment; Lisa Elfring, associate professor of molecular and cellular biology; andVicente Talanquer, professor of chemistry and biochemistry.

The AAU is a nonprofit organization of 62 leading public and private research universities in the United States and Canada. The 60 AAU universities in the United States award more than half of all U.S. doctoral degrees and 55 percent of those in the sciences and engineering.

What's Up UA? - Wildcats Rally, Hail Mary TD Defeats Cal, 49-45

 Anu Solomon threw for a school-record 520 yards, none bigger than the 47 he collected on his final pass of the game as he found Austin Hill in the back of the end zone as time expired to cap a 22-point rally and stun California on Saturday night at Arizona Stadium.

Down 28-6 at the half, UA outscored Cal by a margin of 43-17 in the second half, putting up a blistering 36 points in the fourth quarter alone en route to the 49-45 victory. The win moved Arizona to 4-0 on the season, and was UA’s first Pac-12-opening win since 2010.

“Winning on a Hail Mary is so improbable,” Arizona head coach Rich Rodriguez said. “At first, you’re exhilarated, and then you’re thinking, ‘How did that just happen?’ I’m so happy for Austin Hill. I’m happy for Anu, who was off, but kept battling and executed the last play. I’m happy for the people who stayed and watched the game. It’s a good day to be an Arizona Wildcat.”

Solomon finished the night 47-of-73 for 520 yards and five touchdowns through the air, and ran for a team-high 46 more yards to pace the Wildcats to 627 yards to total offense on the night. He broke Willie Tuitama’s record of 510 passing yards set at Washington in 2007, while also breaking Matt Scott’s records for completions and attempts in a game.

Cayleb Jones had 13 catches for 186 yards and three scores – all career highs – for Arizona, cracking the century mark for the third-consecutive game. Jones’ 13 catches rank on second on Arizona’s single-game chart, while his 186 yards represented the 12th-best single-game effort in program history.

Hill caught all eight of his receptions in the second half, finishing with 127 yards and two touchdowns.

“There’s nothing like a Hail Mary to finish a game,” Hill said. “It means a lot to me that I was able to secure the catch, especially since the offense came back so strong and the defense was playing their butts off. I think this game showed that no matter how far behind we are, we have the maturity to pick ourselves up and learn from mistakes during the game so we can make big plays and come back to get the win.”

Nate Phillips also had eight grabs, accounting for 80 yards, and Trey Griffey and DaVonte' Neal both caught five passes as Solomon distributed his 47 completions between nine different receivers.

The Wildcats racked up 420 yards of total offense and 371 yards through the air after halftime, culminating in one of the most memorable plays in recent Arizona football history.

Scooby Wright III amassed career highs of 18 tackles and two sacks to lead a Wildcats’ defense that yielded just 197 yards of total offense to Cal during the maniacal second-half rally. Tra’Mayne Bondurant had seven tackles, including 1.5 for loss, also coming up with a critical interception and recovering a crucial onside kick to fuel the rally.

Arizona’s defense tallied 10 tackles for loss, including three sacks, broke up three passes and forced a fumble on the night.

The first quarter ended with Cal on top, 14-0, after the Golden Bears reached the end zone on their first two possessions of the game. UA got on the board with a field goal at the 10:39 mark of the second quarter, but Cal was able to answer with a touchdown on the ensuing drive to increase its lead to 21-3.

Casey Skowron added another field goal with 5:28 left in the half to make the score 21-6, but UA saw the Golden Bears answer with another touchdown at the 3:43 mark of the second quarter to push their advantage to the halftime score of 28-6.

“There wasn’t any panic at halftime,” Rodriguez said. “We’re in shape. I told the guys before the game that we were going to have to play for 60 minutes.”

Arizona found pay dirt at the 11:02 mark of the third quarter when Solomon hit Jones for a 41-yard scoring strike, bringing the score to 28-13. The touchdown capped an eight-play, 96-yard drive by the Wildcats.

A Cal field goal with 8:28 left in the third period stretched the margin to 31-13, and Skowron tacked on another field goal for UA with 14:46 left to play draw the Wildcats back within two scores at 31-16.

On Cal’s ensuing possession, Bondurant came up with his first interception of the season on a tipped ball and returned it 24 yards to the Cal 17 yard line. Two plays later, Solomon found Hill for a nine-yard score to cut the deficit to 31-23 with 13:36 left to play.

The Golden Bears scored on their next drive to move out to a 38-23 lead with 10:56 left on the clock, but UA had an answer in the form of a 16-yard touchdown connection between Solomon and Jones with 8:09 remaining. The duo’s second touchdown hookup of the night capped a nine-play, 75-yard drive and brought Arizona within eight at 38-30.

Cal was able to get back into the end zone on their next possession, increasing its lead to 45-30 with 5:21 to play, but Terris Jones-Grigsby punched in a six-yard run with 3:30 remaining to make the score 45-37 and once again bring Arizona within one score.

Bondurant made a huge play for the Wildcats on the ensuing onside kick, stepping in front of a Cal player to secure the ball. UA needed only four plays to reach the end zone, as Solomon connected with Jones yet again, this time from 15 yards out, to make the score 45-43.

Solomon looked for Jones on the two-point conversion attempt to tie the game, but the pass was deflected and fell incomplete.

After the Golden Bears recovered the next onside kick, Cal eventually missed wide left on a 47-yard field goal attempt with 52 seconds left, giving the ball back to UA with no timeouts.

After an offensive pass interference on the first play of the drive set UA back to its own 15 yard line, Solomon methodically worked UA down the field. He converted a fourth-down pass to Hill to set Arizona up on the Cal 47 yard line and spiked the ball with five seconds to play.

On the last snap of the game, the Wildcats finished the job, as Solomon launched a pass into the end zone and Hill battled to come down with it in the back corner for the game-winning score. When the dust settled after an official review, Arizona had won the game by a score of 49-45.

“We work on that one day a week, on Thursday,” he said. “This week, we did a little more. We put in two different kinds of Hail Marys, focusing particularly on where the ball needed to be thrown. I said five yards into the end zone. I think Anu threw it seven-and-a-half.”

After a bye week, Arizona will play its first Pac-12 road contest at Oregon on Thurs, Oct. 2. Slated for 7:30 p.m. MST, the game will be televised by ESPN and carried on the Arizona IMG Sports Radio Network.

What's Up UA? - When Job Loss Equals Weight Gain

Patricia Haynes in the UA College of Medicine has been awarded $3.1 million to study the relationship between unemployment and putting on pounds.

Unexpected job loss is one of the most stressful life events a person can experience, and it affects much more than one's pocketbook. It might also lead to weight gain, research suggests. 

Studies have indicated that unemployed people tend to have a higher body mass index, on average, than those who are employed. A new University of Arizona study will look at why that might be.

Patricia Haynes, assistant professor of psychiatry in theUA College of Medicine, has been awarded a five-year, $3.1 million grant from the National Heart, Lung and Blood Institute, part of the National Institutes of Health, to study the link between job loss and weight gain. She will look specifically at how post-job-loss changes in sleep and social rhythm — a person's daily routine — might affect weight.

"The idea is that unemployed individuals have had a disruption of their daily routine, which is like losing an anchor in the time structure of their day," Haynes said. "Their social rhythm becomes disrupted, which may then impact their biological rhythms and sleep, and increase the propensity towards excessive caloric consumption."

While existing data suggests that insufficient sleep can lead to changes in appetite and satiety hormones, few studies have examined that relationship in a real-world setting, Haynes said.

Haynes developed the idea for the study after listening to National Public Radio. A story about unemployment and the recession was immediately followed by a separate, unrelated story about the country's growing obesity problem. It occurred to Haynes that the two issues might be connected.

The Centers for Disease Control and Prevention estimates about 65 percent of Americans are now overweight or obese. Research suggests that the obesity rate increased during the recession, but the cause for the increase is not entirely clear. Haynes believes that poor sleep quality and disruptions to people's daily routines after job loss could be largely to blame.

Haynes and her research team will follow 250 recently unemployed people over an 18-month period, using smartphones to capture information about participants' daily behaviors in real time. For example, participants might be prompted, via a message on the phone, to report on how they slept the night before, what kind of exercise they did that day or what activity they are doing at any given moment. Select participants also will be asked to take and submit photos of the food they eat. All participants will undergo weight and nutrition assessments in the lab.

Haynes is partnering with the Arizona Department of Economic Security's Unemployment Insurance Administration to identify potential study participants — people who involuntarily lost their jobs within six months of enrolling in the study.

She expects that some study participants will be more vulnerable to weight gain than others. Those hardest hit by the job loss might engage in more sedentary activities, such as watching TV or eating unhealthy foods, she said. At the same time, there may be a subset of more resilient people who see job loss as an opportunity to devote more time to exercising or improving their health.

Haynes also is interested in exploring the effects of re-employment — that is, how a person's sleep, daily routine and weight is impacted if he or she finds new employment during the course of the study.

Haynes hopes that the results of her study will inform health and weight interventions and programs for the recently unemployed.

"Sleep and social rhythms are highly amenable to change by behavioral intervention," she said. "Therefore, these data will help us determine whether typical weight-loss programs might be enhanced by also targeting sleep and social rhythms."

Dr. Ole Thienhaus, professor and head of the Department of Psychiatry in the UA College of Medicine, said the study could have a broad impact.

"Unemployment, chronic sleep restriction and obesity are highly prevalent social and public health issues," he said. "I anticipate that the results of this study will be of high relevance to a large segment of the U.S. population."

Haynes is a behavioral sleep medicine specialist and clinical psychologist who studies insomnia, stress and how people's daily behaviors affect sleep. As director of the UA's Stress and Trauma Recovery Clinic, her research includes studies looking at sleep and post-traumatic stress disorder.

Her collaborators on the unemployment study include Emily A. Butler, associate professor of family studies and human development in the UA College of Agriculture and Life SciencesDuane Sherrill, professor of biostatistics in the UA's Mel and Enid Zuckerman College of Public HealthGraciela Silva, assistant clinical professor of nursing in the UA College of NursingCynthia Thomson, UA professor of public health and director of the Canyon Ranch Center for Prevention and Health Promotion; Dr. Stuart F. Quan, professor emeritus of medicine, pulmonary and critical care medicine in the UA College of Medicine and the Gerald E. McGinnis Professor of Sleep Medicine at Harvard Medical School; George W. Howe, professor of psychology and psychiatry at George Washington University; and Nirav Merchant, director of information technology for Arizona Research Laboratories at the UA.
