Prison Return Rate Down, Data Download, Iowa Department of Corrections, October 2010

The Iowa Department of Corrections has set a goal to reduce the rate of return to prison – whether due to new convictions or technical violations – to 33.3%. Preliminary findings show that that goal has been achieved for FY 07 releasees, with recidivism rates the lowest among the three years studied.

Prison Return Rate Down-Again, Data Download, Department of Corrections

One of the key statistics that Iowa Corrections maintains to measure the success of our efforts is the three-year return-to-prison rate for offenders leaving prison and reentering the community. As the chart below shows, the rate for the three-year period from FY 2009 through FY 2012 is the lowest since this measure has been calculated.

Missouri Work Zone Capacity: Results of Field Data Analysis, TPF-5(081), 2011

This report presents the results of work zone field data analyzed on interstate highways in Missouri to determine the mean breakdown and queue-discharge flow rates as measures of capacity. Several days of traffic data collected at a work zone near Pacific, Missouri with a speed limit of 50 mph were analyzed in both the eastbound and westbound directions. As a result, a total of eleven breakdown events were identified using average speed profiles. The traffic flows prior to and after the onset of congestion were studied. Breakdown flow rates ranged between 1194 to 1404 vphpl, with an average of 1295 vphpl, and a mean queue discharge rate of 1072 vphpl was determined. Mean queue discharge, as used by the Highway Capacity Manual 2000 (HCM), in terms of pcphpl was found to be 1199, well below the HCM’s average capacity of 1600 pcphpl. This reduced capacity found at the site is attributable mainly to narrower lane width and higher percentage of heavy vehicles, around 25%, in the traffic stream. The difference found between mean breakdown flow (1295 vphpl) and queue-discharge flow (1072 vphpl) has been observed widely, and is due to reduced traffic flow once traffic breaks down and queues start to form. The Missouri DOT currently uses a spreadsheet for work zone planning applications that assumes the same values of breakdown and mean queue discharge flow rates. This study proposes that breakdown flow rates should be used to forecast the onset of congestion, whereas mean queue discharge flow rates should be used to estimate delays under congested conditions. Hence, it is recommended that the spreadsheet be refined accordingly.

Issue review : impact on the insurance premium tax rate reduction .

In 2002, Senate File 2318, Insurance Premium Tax Reduction Act, the Iowa General Assembly approved a reduction in the insurance premium tax rate from 2 percent to 1 percent. The reduction was phased in at the rate of 1/4 percent annual increments over a five-year period, beginning with life and health insurance policy payments made on or after January 1st, 2003. Calendar year 2007 was the first year all premiums were taxed at 1 percent and fiscal year 2008 was the first full fiscal year at the 1 percent rate. Insurance premiums tax is paid only by insurance companies. The companies that benefit from the tax reduction are uniquely identified in government employment statistics. This allows for a unique opportunity to evaluate both the revenue impact and the employment impact of the tax rate reduction in Senate File 2318. This issue review focuses on the General Fund revenue impact of the rate reduction and the Iowa employment trends for the insurance industry since the rate reduction legislation was approved.

Improving Portland Cement Concrete Mix Consistency and Production Rate through Two-Stage Mixing, TR-505, 2007

A two-stage mixing process for concrete involves mixing a slurry of cementitious materials and water, then adding the slurry to coarse and fine aggregate to form concrete. Some research has indicated that this process might facilitate dispersion of cementitious materials and improve cement hydration, the characteristics of the interfacial transition zone (ITZ) between aggregate and paste, and concrete homogeneity. The goal of the study was to find optimal mixing procedures for production of a homogeneous and workable mixture and quality concrete using a two-stage mixing operation. The specific objectives of the study are as follows: (1) To achieve optimal mixing energy and time for a homogeneous cementitious material, (2) To characterize the homogeneity and flow property of the pastes, (3) To investigate effective methods for coating aggregate particles with cement slurry, (4) To study the effect of the two-stage mixing procedure on concrete properties, (5) To obtain the improved production rates. Parameters measured for Phase I included: heat of hydration, maturity, and rheology tests were performed on the fresh paste samples, and compressive strength, degree of hydration, and scanning electron microscope (SEM) imaging tests were conducted on the cured specimens. For Phases II and III tests included slump and air content on fresh concrete and compressive and tensile strengths, rapid air void analysis, and rapid chloride permeability on hardened concrete.

Analysis and Forecast of Housing Needs in Iowa Technical Report, January 22, 2013

The research and analysis summarized in this report prepared by Gruen Gruen + Associates (“GG+A”) provides an information base about population, household, housing, and employment conditions and trends affecting the current and future housing needs of Iowans. It also provides a synthesis of how the housing needs of Iowans have changed over the past decade and how needs are likely to continue to change over the present decade (2010-2020), given forecast employment and population growth in Iowa.
