Stop motion effects pioneer Ray Harryhausen dies at 92

Hollywood effects pioneer Ray Harryhausen (Atlantic Wire)The name Ray Harryhausen probably isn’t familiar to the average moviegoer, but fans of today’s science fiction and fantasy films owe a debt to the legendary effects wizard, who died Tuesday at the age of 92.

For decades, Harryhausen was Hollywood’s premiere stop motion effects artist, building models that would seemingly interact with actors on screen in films ranging from “The 7th Voyage of Sinbad” through his final film, 1981’s “Clash of the Titans.”

In recent years, most of Harryhausen’s animation techniques have been supplanted by computer-generated imagery (CGI). But even animators who create their effects entirely on computers today use techniques pioneered by Harryhausen and his tiny, physical models.

Film blogger Devin Faraci writes, “What Ray Harryhausen did was simply magic. He brought inanimate objects to life on screen, and he gave them character and personality that often dwarfed the so-so actors who were up against them. It is no hyperbole to say that the mind (and hands) of Harryhausen shaped the geek revolution that has swept pop culture in the last few decades.”

Beginning his career during the golden age of science fiction, Harryhausen counted many of the genre's towering figures among his contemporaries. For example, Harryhausen joined the Los Angeles Science Fantasy Society at the urging of friend Ray Bradbury in the 1930s. Bradbury would go on to write some of science fiction and fantasy’s most seminal novels, including "Fahrenheit 451" and "The Martian Chronicles."

Along the way, Harryhausen created the effects for some of the most-beloved genre films in history, including titles such as “Jason and the Argonauts.”

And with a backlash to what many consider an over-reliance on digital effects, it’s likely that Harryhausen may appeal to new generations of fans.

Research Examines the Effects of Transit Service Restructuring in Tallahassee FL

SAN JOSE, Calif., May 7, 2013 /PRNewswire-USNewswire/ -- After StarMetro, the public transit agency in Tallahassee FL, restructured its bus network from a radial system to a grid system, some challenges remained. Researchers at the Mineta Transportation Institute (MTI) just completed an analysis of the issues and preliminary outcomes surrounding that change. The report could be useful for transit agencies or others contemplating a similar move. Analyzing the Effects of Transit Network Change in a Decentralized, Small-to-Mid-Sized U.S. Metropolitan Area on Agency Performance and Riders: A Case Study of Tallahassee, Florida is available for free download from http://transweb.sjsu.edu/project/1102.html. Principal investigator Jeffrey Brown, PhD, is available for interviews. MTI was established by Congress and is affiliated with San Jose (CA) State University.

This research seeks to understand: 1) the effects of the service restructuring on the transit agency and its performance, 2) the effects of the service restructuring on transit riders and the larger community, and 3) the roles, influence, and attitudes of important local stakeholders who engaged in the restructuring debate and shaped the restructuring itself.

"StarMetro changed its bus network in July 2011 from a radial to a grid system because local officials and agency leaders believed would better serve the dispersed local pattern of population and employment," said Dr. Brown. "This major service change occurred literally overnight, but it followed several years of public discussion and debate about the future of public transit in the community. The change has been embraced by some people and opposed by others, which is expected given the dramatic and unprecedented system adjustments."

Although the changes are still new, noted Dr. Brown, the research report's short-term, or preliminary, results still offer important lessons to transit agencies, local officials, and transportation researchers regarding the consequences of major transit service changes for agencies and the community.

For example, overall ridership and productivity are lower than before the restructuring due to the short timeframe for rider adjustments and longer-than-anticipated headway. However, new ridership has appeared in previously un-served or under-served corridors and neighborhoods. The restructuring also resulted in longer walks to bus stops because stops were removed from many neighborhoods and relocated to major roads. Overall transit travel times are shorter due to more direct routing. No particular neighborhoods or community groups disproportionately benefited from or were harmed by the change.

The report offers takeaways and lessons
A key takeaway from the study is that restructuring from a radial to a decentralized transit system can increase accessibility, if done right, but such a change requires careful attention to community concerns about route changes, stop locations, headways, access, and safety.

In addition, a longer time horizon is needed to see the results of a major service restructuring such as this. The net result is a modest decline in ridership and in productivity to date. Nevertheless, most local observers feel that the changes represent a clear step forward for transit's future in the community.

Dr. Brown said, "More research is clearly needed to explore the results over the long term and to determine what kinds of service levels – especially headways – are necessary and fiscally sustainable to make decentralized systems effective in such urban environments. The accessibility investigations presented here touched on issues of equity, which are also areas worthy of additional investigation."

The research team also included Florida State University doctoral candidates Tuna Batuhan, Torsha Bhattacharya, and Michal Jaroszynski.

9 negative effects divorce reportedly has on children

Divorce can be the first in a string of dominos that knock a kid down — and keep him there

Divorce is hardly an exception anymore. In fact, with the rate of marriage steadily dipping over the past decade, and the divorce rate holding steady, you are likely to know more previously married couples than those who are legally bound. Accompanying this trend are multiple studies analyzing the effects that divorce has on children. And the results aren't good, even if the stigma of divorce has faded. Here, 9 negative effects divorce reportedly has on children:

1. Smoking habits
In a study published in the March 2013 edition of Public Health, researchers at the University of Toronto found that both sons and daughters of divorced families are significantly more likely to begin smoking than peers whose parents are married. In an analysis of 19,000 Americans, men whose parents divorced before they turned 18 had 48 percent higher odds of smoking than men with intact families. Women had 39 percent higher odds of picking up the habit. Lead author Esme Fuller-Thomson called the link "very disturbing."

2. Ritalin use
Dr. Strohschein, a sociologist at the University of Alberta, wanted to know what was behind the increase in children prescriptions for Ritalin over the past two decades. And so, in 2007, she analyzed data from a survey that was conducted between 1994 and 2000. In it, 5,000 children who did not use Ritalin, and were living in two-parent households, were interviewed. Over the six years, 13.2 percent of those kids experienced divorce. Of those children, 6.6 percent used Ritalin. Of the children living in intact households, 3.3 percent used Ritalin. Strohschein suggests that stress from the divorce could have altered the children's mental health, and caused a dependence on Ritalin.

3. Poor math and social skills
A 2011 study by the University of Wisconsin-Madison found that children of divorced parents often fall behind their classmates in math and social skills, and are more likely to suffer anxiety, stress, and low self-esteem. The reason that math skills are affected is likely because learning math is cumulative. "If I do not understand that one plus one is two," lead researcher Hyun Sik Kim says, "then I cannot understand multiplication." Kim says it is unlikely that children of divorce will be able to catch up with their peers who live in more stable families.

4. Susceptibility to sickness
In 1990, Jane Mauldon of the University of California at Berkeley found that children of divorce run a 35 percent risk of developing health problems, compared with a 26 percent risk among all children. Mauldon suggests their susceptibility to illness is likely due to "very significant stress" as their lives change dramatically. Divorce can also reduce the availability of health insurance, and may lead to a loss of certain factors that contribute to good health, including constant adult supervision and a safe environment. The risk of health problems is higher than average during the first four years after a family separation, but, curiously, can actually increase in the years following. 

5. An increased likelihood of dropping out of school
A 2010 study found that more than 78 percent of children in two-parent households graduated from high school by the age of 20. However, only 60 percent of those who went through a big family change — including divorce, death, or remarriage — graduated in the same amount of time. The younger a child is during the divorce, the more he or she may be affected. Also, the more change children are forced to go through, like a divorce followed by a remarriage, the more difficulty they may have finishing school.

6. A propensity for crime
In 2009, the law firm Mishcon de Reya polled 2,000 people who had experienced divorce as a child in the preceding 20 years. And the results did not paint a positive picture of their experiences. The subjects reported witnessing aggression (42 percent), were forced to comfort an upset parent (49 percent), and had to lie for one or the other (24 percent). The outcome was one in 10 turned to crime, and 8 percent considered suicide.

7. Higher risk of stroke
In 2010, researchers from the University of Toronto found a strong link between divorce and adult risk of stroke. However, the vast majority of adults whose parents divorced did not have strokes. "Let's make sure we don't have mass panic," said lead researcher Esme Fuller-Thompson. "We don't know divorce causes stroke, we just know this association exists." She says the relationship could be due to exposure to stress, which can change a child's physiology. She also noted that the time at which these children experienced divorce was in the 1950s, when it wasn't as socially accepted as it is today.

8. Greater chance of getting divorced
University of Utah research Nicholas H. Wolfinger in 2005 released a study showing that children of divorce are more likely to divorce as adults. Despite aspiring to stable relationships, children of divorce are more likely to marry as teens, as well as marry someone who also comes from a divorced family. Wolfinger's research suggests that couples in which one spouse has divorced parents may be up to twice as likely to divorce. If both partners experienced divorce as children they are three times more likely to divorce themselves. Wolfinger said one of the reasons is that children from unstable families are more likely to marry young.

9. An early death
And rounding out the dreary research is an eight-decade study and book called The Longevity Project by Howard Friedman and Leslie Martin. Starting in 1921, researchers tracked some 1,500 boys and girls throughout their lives. More than one-third of the participants experienced either parental divorce or the death of a parent before the age of 21. But it was only the children of divorced families who died on average almost five years earlier than children whose parents did not divorce. The deaths were from causes both natural and unnatural, but men were more likely to die of accidents or violence. Generally, divorce lowered the standard of living for the children, which made a particular difference in the life longevity of women.
