A four-year-old male with cerebral palsy and spasticity, as a result of a non-accidental head injury sustained when he was two years old, died of pneumonia. Postmortem full body X-rays revealed fractures of varying ages of the left humerus and both femora, tibiae, and fibulae. This led to a thorough investigation of the case by the Office of the Chief Medical Examiner. Child abuse, accidents, metabolic bone disorders, other primary or secondary diseases of the bones, and pathological fractures were ruled out. The final diagnosis was spontaneous fractures secondary to osteopenia. The term spontaneous fractures is used to define fractures that occur without any known external cause, especially in cerebral palsy patients with spasticity. 相似文献

Empirical studies of violence and mental illness have used many different methods. Current state-of-the-art methods gather
information from both subject and collateral interviews as well as official records. Typically these sources are treated as
additive. Any report of a violent incident from any source is treated as true and all reported incidents are added to generate
estimates of frequency. This paper presents a new statistical technique that uses the level of agreement between the sources
of data to adjust those estimates. The evidence suggests that, although the additive technique for using multiple sources
correctly estimates how many people are involved, it substantially underestimates the number of incidents. The new technique
substantially reduces both false negatives and false positives. 相似文献

Objectives
A broad research literature in criminology documents key aspects of how criminal offending develops and changes over the life span. We contribute to this literature by showcasing methods that are useful for studying medium-term patterns of subsequent criminal justice system involvement among a sample of serious adolescent offenders making the transition to early adulthood.Methods
Our approach relies on 7 years of post-enrollment follow-up from the Pathways to Desistance Study. Each person in the study was adjudicated delinquent for or convicted of one or more relatively serious offenses during adolescence. Their local jurisdiction juvenile court petition records and their adult FBI arrest records were systematically searched.Results
We estimate in-sample 7 year recidivism rates in the 75–80 % range. Our analysis also provides recidivism rate estimates among different demographic groups within the sample. Extrapolated long-term recidivism rates are estimated to be on the order of 79–89 %.Conclusions
The Pathways data suggest that recidivism rates of serious adolescent offenders are high and quite comparable to the rates estimated on other samples of serious offenders in the extant literature. Our analysis also reveals a pattern of heightened recidivism risk during the earliest months and years of the follow-up period followed by a steep decline.415.
Sex roles,personality, and intellectual abilities in adolescents 总被引:1,自引:0,他引:1

The relationship between personality variables associated with sex roles and the cognitive variables of math and verbal ability was examined in three groups of adolescents. Masculinity and femininity of interests, behavioral traits, and values were examined using three inventories: the Femininity Scale from the California Psychological Inventory, the Bem Sex Role Inventory, and the Study of Values. Results indicate that there is some evidence for a positive relationship between masculine traits and values and math ability, and feminine traits and values and verbal skills (for both sexes). Certain traits indicative of maturity were found to be positively related to both high math and high verbal scores, while certain highly sex-typed traits and interests were found to be negatively related to both cognitive variables. A different relationship for males and females was found between high intellectual scores and indicators of self-concept and emotional well-being. The differing relationship between each of the three personality variables indicative of sex roles (e.g., interests, values, traits) and cognitive variables emphasizes the need to view masculinity and feminity, as well as sex-role, as a complex combination of the many different aspects of sex roles as they exist in our society.This article is based on a doctoral dissertation submitted to the Department of Psychology, The Johns Hopkins University.Received Ph.D. in psychology from Johns Hopkins University. Main research interests are gifted adolescents, sex-role development, and personality development. 相似文献

There is an inherent trade-off in federalism regarding representation and equity. With the devolution of responsibilities to regional governments offering increased representation, there comes the inequity of services provided by some governments and not others. However, citizens in these federations may want the best of both worlds—desiring regional control but without the regional policy variation. This tension, dubbed ‘the devolution paradox’ in a study of federal countries in Europe, was less apparent in one key group of regions—those with historic ties through language, culture, or experience. This article examines US respondents to identify whether the devolution paradox is evident in this country and looks specifically at the South, a region with long-standing distinctiveness. We find that there is evidence of the devolution paradox among the American public and that the South is indeed different. 相似文献
