Susanne Lindgren Projects aims to keep surgeons operating Its
a fair bet most patients want their surgeons comfortable and happy when
the cutting starts. Unfortunately, surgeons who use less invasive laparoscopic surgery techniques are often just the opposite. Theyre forced to work with long, awkward instruments while viewing fish-eye video images from a small camera, all of which lead to repetitive stress injuries. Sac State professor Warren Smith is trying to help. Laparoscopic surgery, which involves smaller incisions than traditional surgery, is wonderful as far as patient recovery goes. So Smith is focused on making the operations less taxing for the surgeons. For the last six years, he and student assistants have been perfecting a computer-controlled Ergonomic Workstation to monitor surgeons mental and physical stress. Theyre trying to identify where the worst stress occurs so improvements can be made. And now Yale University researchers, who are working in the same area, have purchased the system for their own studies. This is a huge issue for surgeons, Smith says. Hopefully, research using this system will help companies develop better instruments, and help hospitals develop better operating rooms and procedures. It isnt simpleor inexpensiveto turn an eager student into a surgeon. They usually spend at least nine years in training after earning their four-year college degrees, according to the American Medical Association. The longer they can extend their career after that, the better. Smith got started after talking with Martinez surgeon Ramon Berguer, who was concerned about the number of surgeons suffering from injuries such as carpal tunnel syndrome, sore backs and shoulders, and loss of feeling in their fingers. Smith and his students introduced their first monitoring system five years ago at a medical conference in San Diego. Volunteer surgeons were wired to the computer, which then measured muscle movement while they performed various tasks with surgical instruments. The surgeons were very interested, Smith says. One after another they would tell us about pains in their shoulder or thumbs going numb, all related to the use of their instruments. Here were these doctors asking us engineers if we could help with medical problems. After years of improvements, the latest system is much more sophisticated. It now measures muscle movement, brain waves, hand sweat, heart rate, and the angle of arms and head. The system is now wireless, which made wearing it much more comfortable for surgeons. A very small computer is worn in a belt pouch and sends signals to the main laptop computer. It doesnt interfere with surgery, so Yale University has been able to use it to monitor surgeons in operations on human patients. It also works with a multi-camera system, so researchers can record what the surgeon was doing when physical and mental stress levels changed. (back to top) Left in a heros wake The
events of Sept. 11 brought an intense outpouring of appreciation for firefighters
and other law enforcement personnel. But for the families and co-workers
left behind, the adulation is likely to be bittersweet, says psychology
professor Rebecca Cameron.Cameron, a clinical psychologist, studies the impact of traumatic stress on firefighters and their partners. She says that when a spouse, family member or friend dies a hero, the surviving loved one has to deal with more than loss. As in any grief process there may be anger, especially if they had argued with the person before they died. In this situation, survivors may especially wonder if theyre entitled to their anger, Cameron says. Guilt is largely amplified. All the normal feelings that encompass grief are potentially more challenging in light of this person now being revered. Any time a firefighter is killed it affects a community. But its unprecedented to have hundreds killed at once, Cameron notes. In the aftermath of the terror attacks individual losses may have been overshadowed by the enormity of the situation. Those left behind may feel their loss was diminished now that their family member is one in a sea of names, she says. Also the surviving relatives want to be seen as model family members. Its hard to live up to that status. The burden rests with the surviving firefighters as well. Firefighters are an exceptional group. They tend to be very family-oriented, she says. Although firefighters routinely encounter death and injury, when the victim is known or is a co-worker, it is more salient. As the country continues to get back to normal its inevitable outward displays of community support for public safety officials and their families will wane, and may bring a new feeling of loss. Cameron notes that those who were in the spotlight may have to readjust to being out of it. Having once been a hero is difficult, she says. (back to top) Computing
a cultural difference Arts add texture to learning
For Dickens, life is a carnival Even
if theyre unaware of it, most people are familiar with Charles Dickens
works. Sayings from his writings such as Bah, humbug! and It
was the best the times, it was the worst of times
have become
part of popular culture.His novels have inspired innumerable plays, paintings, musical compositions, films, television adaptations and websites. But why does Dickens remain popular? According to Mark Hennelly, chair of Sac States English department, its Dickens way of romanticizing everyday life. After all, trifles make the sum of life, said Dickens character David Cooperfield. Hennelly researches Dickens writings and lifestyle, and has published more than 15 essays and reviews about the famous author. What most captivates him is the way Dickens played with contradictions. On the one hand, he had to be very disciplined in order to be published. He made an art form out of the periodic novel, writing 32 pages a month for 19 months at a time, and he only missed a deadline once. But, on the other hand, he was very restless. He would walk all night, sometimes 20 miles to London and back, and he was an agitator for reform and for the lower class. He also regularly hosted carnivals in his backyard, that involved the entire town. The contradictions, the discipline and the restlessness, are very provocative. Hennelly is currently researching a carnivalesque reading of the novel Martin Chuzzlewit, which he hopes to publish in a journal dedicated to Dickens. He loved fairs and carnivals, in his life and in his writings, Hennelly says. There are a number of different carnival figures likes clowns, fools and rogues in his fiction, but perhaps the most interesting symbol of the carnivalesque play is the motif of the somersault. It joins heaven and earth, and because what was on the bottom replaces what is on the top, it represents a reversal of conventional categories of value. (back to top) Perceptions sway athlete play In
the world of amateur sports, what you believe is what you get, says
kinesiology and health science professor Gloria Solomon. If the coach doesnt
have confidence in an athlete, the athlete rarely improves.In several studies of college and high school player-coach interactions, Solomon found the feedback an athlete receives from his or her coach has an effect on athletic performance. And head coaches give significantly better feedback to athletes they deem high expectancy players, which leads to higher performance. More surprisingly, Solomon learned that when athletes were considered high-expectancy, it wasnt based on athletic ability or athlete confidence. The predictor of actual performance was the coachs perception of the athletes confidence, says Solomon, a certified sport psychology consultant who has been both a coach and an athlete. For several years Solomon has been testing expectancy theory, which looks at the effect of one persons expectations on anothers performance. I wondered how some coaches could bring out the best in athletes while others couldnt, she says. Expectancy theory had been used in education, but Solomon is the first to find relationship between expectancy and athletic performance. Her findings have been published in several professional journals, most recently in the International Journal of Sports Psychology. Another revelation came during a study that documented the actual feedback coaches issued to athletes at practices. When you ask coaches to reflect on the feedback theyve given, they see themselves more positively than was the case, Solomon says. The athletes, on the other hand, are very accurate in remembering what was said. Coaches are a little disconnected from what they say and what athletes pick up on and remember. Solomon saw positive signs when she looked at interactions between coaches and athletes in youth sport, and between assistant coaches and athletes in high school and college. There was not the same difference in feedback among youth sport coaches. (back to top) E. coli: Lurking in a store near you? Back
away from that burger unless youve taken its temperature. Ground
beef purchased in the Sacramento area shows occurrences of a toxic form
of E. coli, says Susanne Lindgren, a Sac State biology professor. As part of a recent study, Lindgren and graduate student Julie Oliver tested 200 samples of ground beef from a variety of outlets from high-end grocery chains to warehouse stores. They found an 11 percent positive rate of the enterohemorrhagic, or EHEC, strain of E. coli, which can cause serious illness. Across the board, regardless of fat content or the store where the meat was purchased, EHEC was there, Lindgren says, even though the USDA has a zero tolerance for it. The good news, Lindgren says, is that consumers can protect themselves from potential illness by following safe food preparation procedures, including thoroughly cooking ground beef. We need to educate consumers to handle food well. I think its unrealistic to expect food to be EHEC-free, she says. Not all bacteria are bad. E. coli is the number one aerobic bacteria in our intestines and there are more good E. coli in the world than bad, Lindgren points out. And meat can contain as much as 100,000 bacteria per gram before it is cooked. Look, its there. It may not be EHEC but until you know what it is, its a good idea to follow the guidelines. Lindgrens and Olivers analysis of the ground beef involved looking for the gene of an EHEC toxin in each sample. With this method, you can get really low levels of detection, Lindgren says. The next phase of the project will be to try to reduce the viability of the pathogen. We want to see what conditions it can survive in, Lindgren says.
