We address the development of a normalization theory for object-oriented data models that have common features to support objects. We first provide an extension of functional dependencies to cope with the richer semantics of relationships between objects, called <italic>path dependency, local dependency,</italic> and <italic>global dependency</italic>(More)
The purpose of this study was to describe the pattern of change in effort sense and the value of this pattern in predicting work end-point at relatively high work intensity (80% VO2 max). The patterns of change of various physiological functions were also observed. Two modes of work (walking and running) were compared to ascertain generalizability of(More)
In this study we investigated the reliability and validity of the Rorschach Schizophrenia Index (SCZI) from Exner's (1978, 1993) Comprehensive System for a sample of 413 child psychiatric inpatients by examining relationships with the Personality Inventory for Children-Revised (PIC-R) and chart diagnoses. Interscorer reliability and internal consistency(More)
This paper addresses the problem of recovering object-oriented schemata from relational databases. Solutions to this problem are particularly useful for designing wrappers for federated database systems. Our goal here is to describe a reverse engineering methodology for the DOK federated database system Tari et al. 1996, enabling the wrappers to express(More)
Adolescent inpatients with a diagnosis of alcohol abuse (n = 28), nonalcohol substance abuse disorders (n = 15), or psychiatric disorders without substance abuse (n = 46) were examined on measures of attentional, intellectual, and personality functioning. High scores on a personality measure, the Substance Abuse Proclivity Scale (SAP), was the best(More)
To date, relatively few studies have been published evaluating the validity or incremental validity of the content scales from the adolescent version of the Minnesota Multiphasic Personality Inventory (MMPI-A; J. N. Butcher et al., 1992). A sample of 629 psychiatric inpatient adolescents who had completed the MMPI-A was used to evaluate the ability of(More)
This study explored the associations between response-bias features, parenting stress, and parent-child discrepancies in self-report and parent ratings of psychopathology in a sample of 153 preadolescents from an inpatient psychiatric setting. Correlational and multiple regression analyses utilized combinations of dissimulation (FB) and defensiveness (DEF)(More)
Depressed adults have deficits in memory functions, especially on demanding tasks, but few studies of depressed adolescents have been published. In order to examine the extent of memory impairment and its diagnostic specificity, adolescent inpatients with DSM-III-R diagnoses of Major Depression (n = 56), Conduct Disorder (n = 42), or mixed Depression and(More)
We explored the validity of the Psychopathology Five (PSY-5) facet scales of the adolescent version of the Minnesota Multiphasic Personality Inventory (MMPI-A; Butcher et al., 1992) in an adolescent inpatient psychiatric sample (N = 662) through a series of correlational analyses with self-report measures, therapist ratings, and chart review variables.(More)
Failure in medication compliance in adult psychiatric patients is often found to be due to side effects or associated with unawareness of illness. Little research has been conducted on medication compliance in adolescent psychiatric patients. In this study, 97 adolescent psychiatric patients, including 46 with substance abuse, were followed up an average of(More)
