Investigation of Restraint Device use in Iowa's County Jail

Executive Summary The use of full-body restraint devices is a widespread practice in Iowa’s county jails. Full-body restraints come in the form of restraint chairs, boards, and beds, including two such devices manufactured in Iowa. Iowa law, which refers to these as four- and fivepoint restraints, states they are only to be used when an inmate is a threat to self, others, or jail security. However, the Ombudsman found they were also used on inmates who caused minor disruptions or in response to an inmate’s verbal abuse. In some cases, the restraints were used on inmates with known mental illness who were acting out, though no attempts were made to seek medical or mental health reviews for those inmates while restrained, leading to extended use of the restraint device.

Leadership Agenda and Strategic Progress Report, 2007-2008

Early Childhood Iowa (ECI) is an alliance of stakeholders in early care, health, and education that affect children age zero to five in the State of Iowa. Its purpose is to support a comprehensive, integrated early care, health and education system for Iowa. All activities of the system are aligned around a common vision for Iowa: Every child, beginning at birth, will be healthy and successful.Membership is voluntary and open to anyone self-identifying as a “stakeholder” in Iowa’s early care, health, and education system. The process for membership will be with as few barriers or constraints as possible. Individuals seeking membership should agree to the vision for an early care, health, and education system in Iowa and to the principles and core beliefs of the ECI Stakeholders. The structure of ECI includes six system component groups that describe the necessary elements of an effective and comprehensive early care, health, and education system, as well as a State Agency Liaison group and a Co-chairs group. Membership in each component group is open to anyone with an interest in the unique responsibilities of a implementing an early care, health and education system.

The Utilization of Agriculturally Derived Lignin as an Antioxidant in Asphalt Binder, TR-557, 2008

Oxidation is the primary cause of long-term aging in asphalt pavements. As a pavement oxidizes, it stiffens and can eventually crack. The use of an antioxidant as a performance enhancer in an asphalt binder could delay aging, thus increasing the life of an asphalt pavement. Lignin is a highly available and well-studied antioxidant. A wet-mill ethanol plant produces several co-products, some of which contain lignin. The use of lignin from ethanol production could provide a benefit to asphalt pavements and also give more value to the co-products. The following research examined the effects of lignin on asphalt pavements. Three lignin-containing co-products were separately combined with four asphalt binders in varying amounts to determine the optimum amount of co-product that would provide the greatest benefit to the asphalt binders. The asphalt binder and co-product blends were evaluated according to Superpave specifications and performance graded on a continuous scale. The data indicated a stiffening effect on the binder caused by the addition of the co-products. The more a co-product was added, the more a binder stiffened. Binder stiffening benefited the high temperature properties and the low temperature binder properties were negatively affected. However, the low temperature stiffening effects were small and in many cases not significant. The co-products had an overall effect of widening the temperature range of the binders. This result suggests some antioxidant activity between the binder and the lignin. Testing with a fourth co-product with no lignin supported the idea that lignin acts as an antioxidant. The samples with no lignin aged significantly more than the samples with lignin. Infrared spectrometry also supported the idea that lignin acts as an antioxidant by observing decreases in some oxidative aging products.
