Iowa's Adult Basic Education Program Annual Benchmark Report Executive Summary, 2005

The purpose of this publication is to present the Executive Summary for the Program Year 2002 report on Iowa’s adult basic education program benchmarks. The passage of the Workforce Investment Act (WIA) of 1998 [Public Law 105-220] by the 105th Congress has ushered in a new era of collaboration, coordination, cooperation and accountability. The overall goal of the Act is “to increase the employment, retention, and earnings of participants, and increase occupational skill attainment by participants, and, as a result improve the quality of the workforce, reduce welfare dependency, and enhance the productivity and competitiveness of the Nation.”

I-74 Iowa-Illinois Corridor Study, Vol 1, Winter 2005

The I-74 Iowa-Illinois Corridor Study has been progressing since the last newsletter and the Public Information Meetings in July of 2002, and the Advisory Committee has been involved in every step. Our goal has been and continues to be ensuring that community priorities and goals are reflected in the I-74 project, and that local concerns are considered.

State Legislation Monitoring Report FY 2005, February 2006

The Division of Criminal and Juvenile Justice Planning issued its first state legislation monitoring report in February 2002, covering the first six months’ impact of Senate File 543 (which enacted a number of sentencing changes) on the justice system; monitoring of the correctional impact of this bill was at the request of several members of the legislature. Since then, the Criminal and Juvenile Justice Planning Advisory Council has requested that CJJP monitor the correctional impact of enacted legislation of particular interest.

Juvenile Recidivism Report, December 2005

The following report contains district-level numbers for the percent of juveniles in Iowa’s Juvenile Court System and the number who re-offended (subsequent complaint/s). These numbers represent the data available in the ICIS system for initial complaints in 2002, an subsequent complaints. The report also includes recidivism numbers for those counties that had more than 180 initial complaints These numbers are representative, but are not state totals. All districts are represented, but no all counties. The 5th District only includes Polk County due to a data migration issue that, at this time, does not allow the remaining 5th District counties data to be analyzed.

Evaluation of PCC Specification Changes Impact on Durability: 1992 - 1997 Core Study, MLR-98-06, 2005

In 1990, early distress had shown up on US 20 in Hamilton/Webster counties, three years after paving. Since that time, over a dozen more projects, constructed between 1984 and 1994, have been found to exhibit similar early distress. Several changes to the concrete and Portland cement specifications occurred in 1994 and 1996. This study was undertaken to investigate in place concrete pavements before and after specification changes were implemented. The objective of this research is to evaluate the impact of Portland cement and concrete specification changes made in 1994 and 1996 on PCC durability. Cores were obtained in 1998 and 2003 from projects constructed in 1992, before specification changes, and 1997 after specification changes. The following is a brief summary of the conclusions: 1. The pavements in the study constructed under the new specifications are performing much better after 5 years of service than the pavements constructed under the old specifications. 2. According to ISU, micro-cracking is evident in all concrete that has been in service, due to thermal stresses and loading stresses. Also, the low vacuum SEM will desiccate the concrete enough to cause micro-cracking. The SEM should not be used as a tool to indicate micro-cracking. 3. Use of Type II cement (C3A <8%) and a 3.0% SO3 limit does not completely eliminate ettringite infilling in air voids, as indicated in the bottom of the 1997 cores. 4. In areas of high moisture (bottom of the core), infilling is present in most of the 1997 cores. 5. Low air content and high spacing factor in the top of 1992 cores apparently causes F/T cycling cracking and then increased moisture paths from cracking causes infilling. 6. Use of ground granulated blast furnace slag (GGBFS) and fly ash reduces ettringite infilling either by diluting the aluminate (C3A) or lowering permeability, which slows ingress of moisture. 7. The specification changes that made the biggest impact on pavement durability are the limits on vibration and increase in air content in September 1994. 8. Investigations of cores from pavements placed in 2002 and 2003 indicate improved air contents and spacing factors. In-place air content and spacing factors should be monitored to determine if appropriate air void parameters are being met.
