The Third Report Assessing the Chicago Police Department's Compliance with the Investigatory Stop &Protective Pat Down THE THIRD REPORT ASSESSING THE CHICAGO POLICE DEPARTMENT’S COMPLIANCE WITH THE INVESTIGATORY STOP & PROTECTIVE PAT DOWN AGREEMENT The Investigatory Stop Report (“ISR”) data from CY2017 continues to reflect areas of non-compliance with the Chicago Police Department’s Stop & Frisk Policy and the Fourth Amendment to the United States Constitution.

  • What Affirmative Action? Where Are the Minority Educators in the Metropolitan Chicago Schools?
    DOCUMENT RESUME ED 403 348 UD 031 461 AUTHOR Heller, Rafael TITLE What Affirmative Action? Where Are the Minority Educators in the Metropolitan Chicago Schools? INSTITUTION Chicago Urban League, Ill.; Latino Inst., Chicago, IL. SPONS AGENCY Spencer Foundation, Chicago, Ill. PUB DATE [92] NOTE 59p.; Foreword by Gary Orfield. PUB TYPE Reports Evaluative/Feasibility (142) Statistical Data (110) EDRS PRICE MF01/PC03 Plus Postage. DESCRIPTORS *Affirmative Action; Elementary Secondary Education; *Employment Patterns; Enrollment; Equal Opportunities (Jobs); Inner City; *Minority Group Teachers; Neighborhood Integration; Racial Composition; School Segregation; *Suburban Schools; *Teacher Supply and Demand; *Urban Areas; Urban Schools IDENTIFIERS *Illinois (Chicago Metropolitan Area) ABSTRACT Teacher employment patterns in metropolitan Chicago (Illinois) were studied using data from the Illinois State Board of Education. Findings show no signs of affirmative action in many of the region's rapidly growing school systems. In many of the metropolitan area's districts, there is a persistence of segregated employment patterns and the exclusion of minority professionals. A review of hiring patterns in the districts around the city show that no progress is being made in improving minority representation on faculties. Since 1980, suburban minority enrollment has grown to 24.5% of the total, but the minority teaching force has risen only 0.6% to 5.8%. The Chicago suburbs employ nearly 64% of the region's teachers but only 16% of the black teachers. Although 1 in 12 suburban students is Hispanic, only 1 in 100 suburban teachers is Latino. Almost 1 in 12 suburban students is Asian, only 1 of 1,100 principals is from an Asian background.

  • Disparate Impact and Mortgage Lending: a Beginner's Guide
    13. 88.4 GANO_FINAL (DO NOT DELETE) 5/19/2017 4:14 PM DISPARATE IMPACT AND MORTGAGE LENDING: A BEGINNER’S GUIDE ALEX GANO* In the aftermath of the Great Recession, the federal government began to enforce fair lending laws with a vigor previously unseen. To hold lenders accountable for the racially discriminatory effects of their mortgage lending practices, federal prosecutors and financial regulators applied the theory of disparate impact to fair lending laws for the first time. Unclear, however, is what legal standards exist to evaluate allegations of discriminatory effects in this industry. No court has ever decided a fair lending case under a theory of disparate impact on its merits. That will likely change soon as major municipalities are pushing the boundaries of this theory to its outer limits. Last June, the U.S. Supreme Court granted certiorari in Bank of America v. City of Miami to address a pair of discrete issues in this area. This Comment attempts to answer some foundational questions about how the theory of disparate impact will be applied to mortgage lenders moving forward. It also makes a normative argument for judicial acceptance of this theory and continued governmental enforcement of fair lending laws.

Universal Lessons from Illinois’s Fair Tax Failure: 2 How a Rich Minority Wins the Majority Vote Introduction The United States is considered a beacon of democracy; democracies, by design, are meant to promote the interests of the majority while protecting the rights of the minority. However, as income inequality has soared, this basic tenet has come into question, as evidenced by Americans’ weariness to tax the ultrawealthy. In Illinois, a graduated income tax proposal that would raise the taxes of the ultrawealthy, but not on 97 percent of the population failed 55-45 percent.1 At this point, a reasonable person may wonder why this tax referendum is relevant to anyone outside of Illinois.

  • Measuring News Media Literacy How Knowledge and Motivations Combine to Create News-Literate Teens
    Measuring news media literacy How knowledge and motivations combine to create news-literate teens Stephanie Craft, Ph.D., University of Missouri Adam Maksl, Ph.D., Indiana University Southeast Seth Ashley, Ph.D., Boise State University Table of Contents Preface 1 Executive Summary 2 Background 3 Key Findings Focus Groups 10 Survey 13 Plan of Action 19 Appendix A: Methodology 21 Appendix B: Top-Line Results 23 References 32 Acknowledgments 35 Preface The metaphors used to describe the digital, networked, social, interactive and information-rich age in which we live – it’s a wave, a flood, even a tidal wave! – suggest a powerlessness that can be dispiriting. The promise of so much easily accessible information quickly transforms into peril as we wonder just how to make sense of all that abundance, how to find the signal amidst all the noise. Efforts to improve news media literacy are aimed directly at the promise and perils of abundance. Better understanding of what makes news reliable and credible is a first step toward a citizenry that is better equipped to make smarter decisions and engage in democratic society. Before we can take that first step, though, we need to define what, exactly, news media literacy is so that we can develop methods for improving it and recognize whether those methods are successful or not. We were honored and excited to receive generous funding from the McCormick Foundation to develop a tool to aid in these efforts. To date, our research has employed focus groups, surveys, classroom ethnographies and qualitative data analysis to develop an instrument for measuring news media literacy.

MISSING WHITE WOMAN SYNDROME: AN EMPIRICAL ANALYSIS OF RACE AND GENDER DISPARITIES IN ONLINE NEWS COVERAGE OF MISSING PERSONS ZACH SOMMERS* At any given time, there are tens of thousands of Americans categorized as “missing” by law enforcement. However, only a fraction of those individuals receive news coverage, leading some commentators to hypothesize that missing persons with certain characteristics are more likely to garner media attention than others: namely, white women and girls. Empirical investigation into this theory is surprisingly sparse and also limited in multiple ways. This paper aims to fill those voids by empirically exploring whether that inequality, dubbed “Missing White Woman Syndrome,” truly exists.
