Iowa Racial Bias Legal Case



IOWA CITY, Iowa (AP) — In a case closely watched by civil rights activists, an Iowa judge will soon decide whether to grant thousands of black employees and job applicants monetary damages for hiring practices used by Iowa state government that they say have disadvantaged them.
Experts say the case is the largest class-action lawsuit of its kind against an entire state government's civil service system, and tests a legal theory that social science and statistics alone can prove widespread discrimination.
The plaintiffs — up to 6,000 African-Americans passed over for state jobs and promotions dating back to 2003 — do not say they faced overt racism or discriminatory hiring tests in Iowa, a state that is 91 percent white. Instead, their lawyers argue that managers subconsciously favored whites across state government, leaving blacks at a disadvantage in decisions over who got interviewed, hired and promoted.
Judge Robert Blink's decision, expected in coming weeks, could award damages and mandate changes in state personnel policies or dismiss a case that represents a growing front of discrimination litigation.
"Whenever there is a case like this that goes to trial, it's of interest to all of us," said Jocelyn Larkin, executive director of the Impact Fund, a Berkeley, Calif.-based nonprofit that supports employment discrimination lawsuits and has followed the case.
Similar cases against local governments have failed because proving broad bias is extraordinarily difficult, with a myriad of possible factors to explain disparities, said David Friedland, a California human resources consultant who is an expert on discrimination in hiring. Success in Iowa could encourage similar lawsuits elsewhere, he said.
University of Washington psychology professor Anthony Greenwald, an expert on implicit bias who testified on behalf of the plaintiffs, said the decision will be important nationally because similar cases against corporations have usually been dismissed or settled before trial.
Scholars and employment lawyers have shown a growing interest in implicit bias in the last several years, after Greenwald and other scientists developed the Implicit Association Test to test racial stereotypes. Their research found an inherent preference for whites over blacks — in up to 80 percent of test-takers and among many people who do not consider themselves racist.
The theory hit a legal obstacle last year when the U.S. Supreme Court disqualified a class-action lawsuit against Wal-Mart's pay and promotion practices for women. The court found the class was too broad and failed to challenge a specific hiring practice as discriminatory.
Lawyers defending the state have cited that decision in asking Blink to dismiss the case. But the high court's decision did not specifically reject the theory of implicit bias, and dissenting Justice Ruth Bader Ginsburg wrote that such claims can be allowed.
Class attorney Thomas Newkirk said the science and other evidence that shows disadvantaged groups such as blacks face employment discrimination in subtle ways "is becoming overwhelming."
"Clearly, the problem is not in Iowa alone, but we believe Iowa is the exactly the right place to ask society to take control of this important issue fairly for all races, and to seek a better future for all as a result," said Newkirk, who was recently honored by the Des Moines chapter of the National Association for the Advancement of Colored People for his work on the case.
During a monthlong trial last fall, experts called by the plaintiffs' lawyers testified that blacks are hired at lower rates than whites with similar qualifications and receive less favorable evaluations and lower starting salaries. An employment consultant hired by the administration of Gov. Tom Vilsack, who served from 1999 to 2007, warned of hiring disparities between whites and minorities in a report issued after he left office. Larkin called that report a strong "and pretty unusual piece of evidence" proving the state was aware of problems.
Vilsack's successor, Democratic Gov. Chet Culver, responded by issuing an executive order requiring agencies to improve the diversity of the workforce. State officials called that evidence of progress, but class lawyers argued it turned out to be ineffective because rules meant to prevent bias still were not followed.
Republican Gov. Terry Branstrad said last fall his administration had ensured agencies were following uniform rules to stop any abuse — but a top state employment official testified days later he'd seen no substantive changes to hiring practices in years. Blacks represented 2.9 percent of the state's population in 2010 and 2.4 percent of the state workforce.
Among those who joined the lawsuit as a plaintiff was Charles Zanders, of Urbandale, who was passed over for an interview for a position with the Iowa Communications Network in 2008 despite having worked 29 years in the telecommunications industry.
"I was very angry at that time and felt like I'd been stepped on," Zanders, 60, said.
In a brief submitted in December, plaintiffs' lawyers sought lost wages of about $67 million minus what they earned in the meantime. But in court documents, Newkirk said it was even more important that Blink order changes in the way state officials train managers, screen candidates and track disparities in hiring.
Lawyers working for Attorney General Tom Miller, a Democrat, argued that the plaintiffs failed to show bias across state government.
"The record simply does not support Plaintiffs' charge that some monolithic, immutable force of bias infected the decisions made by every department, at every step, for every job, for every year of the class period," they wrote in a final brief last month.

EDSS 541 RR # 2


Activity 7.1:
In discussing possible topics for our ITU Harry and I decided on the controversial subject of Hydraulic Fracturing, also known as "Fracking".  This subject should allow us to incorporate our two disciplines, as well as Social Science, and  English components. Although our two disciplinary focuses are Physics, and Earth/Planetary Science, we will come up with lesson plans that incorporate other potential disciplines (Social Science/Mathematics). 



7.2: Some Essential Questions for our theme:
What are the economic/environmental implications of tapping into this reserve of natural gas? 
This question explores the costs (both economic and environmental) in obtaining a potentially vast reserve of energy. Students will need to weigh benefits and costs (both realized and potential).
How is it possible to apply enough force to fracture a rock formation miles underground?  Which speaks to how fracking works and leads into the subjects of hydraulics, i.e. pressure, Pascal’s principal, how Pascal’s principle reflects the definition of work and how hydraulic systems relate to simple machines.
How does the greenhouse effect work?  Which speaks to the ecological implications of finding abundant new sources of cheap fossil fuels and leads into a whole range of Physics, possibly more than we can really cover.  Quantum theory, optics, the nature of light, the Bohr model of the atom are all needed to understand scattering and the greenhouse effect.  Or, we could leave it at “The Greenhouse Effect”.  
Where does electricity come from?  Which addresses both ecological and political/economic implications of  fracking by way of the fact that natural gas is the currently preferred fuel fior electrical generating plants.  A complete coverage of the question brings in thermodynamics and E&M as well as nuclear physics and solid state physics, if one goes so far as to cover nuclear and solar energy.
