Modern Era of Experimental Modal Analysis: One Historical Perspective, The

Dr. Brown (right) graduated from the University of Cincinnati, Aeronautical Engineering Program with a B.S. degree in 1961. After graduation, as part of a university research contract, he worked at Wright Piittorson Air Force Base in the ARL Hypersonic: Wind Tunnel Facility where he was involved with both analytical and experimental hypersonic: research. After he received his M.S. degree in 1963, Dave took a temporary leave of absence from the University for two years and worked on the Research Staff at General Electric in Cincinnati, studying hypersonic: shockwave boundary layer interactions in hypersonic scramjet inlets as part of another Air Force Project. During his stay at GE, Dave took a self study class in advanced thermo-dynamics from the department head of the Mechanical Engineering Department and when ho returned to the University of Cincinnati, he joined the University of Cincinnati Structural Dynamics Research Laboratory (UC-SDRI,) in the Mechanical Engineering Department. This was the start of his long association with the UC-SDRL. His early work in UC-SDRL was studying cutting mechanics of the grinding process which evolved into "Grinding Dynamics" which became the main title of his Ph.D. dissertation work. During bis study of grinding dynamics, Dave became very involved in the early practical development of Fourier analysis as applied to digital signal processing, acoustics, controls, self-excited and forced vibrations. This work set the stage for subsequent developments in experimental structural dynamics, the area that is often associated with UC-SDRL. During this early period from 1966-1970. Dr. Brown worked on the Research Staff and taught undergraduate and graduate courses in thermodynamics, acoustics and vibrations. In 1970, Dr. Brown became the Director of the UC-SDRl, a position he held until he retired in the fall of 2004. During his tenure, Dave influenced and advised hundreds of students, gave many seminars, consulted with a large number of companies, was published extensively in the above mentioned areas and was invited to give numerous keynote presentations at conferences internationally. Dr. Brown is still teaching an occasional course and he continues to direct research in the areas of acoustics, controls and vibration. His students are his proudest legacy.

MULTIPLE-FAMILY GROUP INTERVENTION FOR INCARCERATED ADOLESCENTS AND THEIR FAMILIES: A PILOT PROJECT

The Multiple-Family Group Intervention (MFGI) was developed to address the need for an effective and yet affordable treatment for reducing recidivism for incarcerated adolescents and altering the families' coercive interactional patterns from an affect regulation and attachment perspective. The 8-week MFGI program was conducted in two Indiana juvenile correctional institutions. The research study utilized pre- and postintervention assessments and a 6-month follow-up assessment. Data from both male (n = 43) and female (n = 30) adolescents were combined, yielding a total sample of 140 respondents (73 adolescents, 67 caretakers). The 6-month follow-up assessment indicated a recidivism rate of only 44% compared to the national norm of 65-85%. Linear growth models were fit to determine the nature of the changes in adolescent behavior over the three assessments. Adolescents and caregivers reported that adolescents' externalizing behaviors significantly declined over time. Adolescent-reported internalizing symptoms as well as their alcohol and drug use significantly declined over the follow-up period, while caregiver reports of these behaviors showed no change over time. Adolescent-reported attachment to their parents, particularly mothers, increased significantly as did both adolescent and caregiver-reported functional affect regulation.

At present, many adolescents after release from correctional facilities to which they have been remanded for criminal behavior return to these delinquent behaviors, alcohol and drug abuse, and sexual offending (Santos, Henggeler, Burns, Arana, & Meisler, 1995). The recidivism rate for incarcerated adolescents is extremely high, hovering in the range of 65-85%;1 many re-offend and are re-incarcerated at great cost to communities, court systems, and mental health service agencies (Deschenes & Greenwood, 1998; Henggeler, 2003; Santos et al., 1995). Often, this cycle is repeated until adolescents reach the age of 18 and transition into the adult mental health and criminal justice systems (Borduin, 1994; Lipsey, 2000).

While incarcerated, the adolescents attend school and individual and/or group therapy, but their relationships with their families are often not targets for treatment. As a result, the coercive interactional patterns common in these families do not improve (Henggeler, Smith, & Schoenwald, 1994; Patterson, 1982, 1994, 2002). These conflictual cycles are associated with high levels of negative emotion that disrupt family members' attachment bonds (Ducharme, Doyle, & Markiewicz, 2002), impair cognitive functioning (Gottman, 1993), and foster chronic physiological arousal (El-Sheikh, 2001; Gottman & Katz, 2002). The result is that adolescents leave the institutions disconnected from their families, unable to cope well with conflict and negative affect/emotion, and therefore are less likely to integrate new information and develop alternative solutions to problems. Instead, they are more likely to revert to old, overlearned and often maladaptive behaviors, leaving them at risk for re-offending and relapse (Henggeler, 2003; Santos et al., 1995). Evidence-based and effective family treatments exist for delinquency and conduct disorder (see Keiley, 2002a, for a review), but many of them are expensive to implement, requiring extensive resources and additional personnel that state-funded juvenile correctional systems seldom can afford. The clinical and research project Multiple-Family Group Intervention (MFGI) was developed and conducted to address the need for effective, yet affordable, treatment for incarcerated adolescents and their families.

Development of Delinquent Behaviors

Adolescents at risk for entry into the juvenile justice system often have already experienced behavior problems in early (Oppositional Defiant Disorder) or late (Conduct Disorder) childhood (American Psychiatric Association, 2000). As a result, they may have social information processing and other cognitive deficits such as hostile attributional bias and poor problemsolving abilities (Dodge, 1993). These processing biases support children's views of the world as unfriendly. seeing only hostility, they limit the means that they use to obtain desired goals to behaviors that are coercive, if not aggressive (Dodge, Pettit, & Bates, 1996). Aggressive children with these cognitive deficits and biases, which interfere with the development of social competence, then may be rejected by typically developing peers, associate with deviant ones, and experience academic failure (Dishion & Andrews, 1995). As adolescents, they often feel alone, fearful of negative evaluation, and full of self-blame (Dodge, 1993). The resulting preponderance of negative affect, lack of useful affect regulation skills, and problems in relationships that the youth then experiences are frequently self-medicated by the use of substances (e.g., alcohol, drugs) or behaviors (e.g., sex, gang membership, violence), and they thus fall into the juvenile justice system (Henggeler & Santos, 1997; Henggeler et al., 1994).
