Comparing NOMINATE and IDEAL: Points of Difference and Monte Carlo Tests

Empirical models of spatial voting allow us to infer legislators' locations in an abstract policy or ideological space using their roll‐call votes. Over the past 25 years, these models have provided new insights about the U.S. Congress, and legislative behavior more generally. There are now a number of alternative models, estimators, and software packages that researchers can use to recover latent issue or ideological spaces from voting data. These different tools usually produce substantively similar estimates, but important differences also arise. We investigated the sources of observed differences between two leading methods, NOMINATE and IDEAL. Using data from the 1994 to 1997 Supreme Court and the 109th Senate, we determined that while some observed differences in the estimates produced by each model stem from fundamental differences in the models' underlying behavioral assumptions, others arise from arbitrary differences in implementation. Our Monte Carlo experiments revealed that neither model has a clear advantage over the other in the recovery of legislator locations or roll‐call midpoints in either large or small legislatures.     

The design and implementation of Family Foster Care Services for high risk delinquents Transitioning from Correctional Confinement

Specialized Family Care (SFC) provides planned, long term family foster care to youth who have been adjudicated as delinquent and who are at high risk of on-going delinquent behavior following their transition into the community from correctional confinement. The program is funded and operated through a collaborative arrangement among The Casey Family Program-Bismarck Division, the North Dakota Department of Human Services (DHS) and the North Dakota Division of Juvenile Services (DJS). Specially recruited, trained and supported foster families work closely with a dual case management system of services provided by SFC social workers and DJS case managers responsible for community-based aftercare. Individual case plans for youth involve a mix of intensive aftercare programming for delinquent behaviors, individually designed intervention strategies, intensive supervision, and intensive casework. This article discusses the program model, implementation challenges, costs and preliminary outcomes.     

PRISON GUARDS AND THE USE OF PHYSICAL COERCION AS A MECHANISM OF PRISONER CONTROL*

This paper examines the dynamics of the use of unofficial force by prison guards in a Texas penitentiary. The findings suggest that rather than being idiosyncratic or sporadic, guard use of physical coercion was highly structured and deeply entrenched in the guard subculture Upperranking guards served as mentors and socialized younger nonmnking guards into the process of using physical coercion. These nonranking guards actually served as apprentices. Most importantly, guards who used physical force were rewarded for their behavior with improved duty posts or even promotions.
