The Roles of Mothers’ Neighborhood Perceptions and Specific Monitoring Strategies in Youths’ Problem Behavior

The neighborhood context can interfere with parents’ abilities to effectively monitor their children, but may be related to specific monitoring strategies in different ways. The present study examines the importance of mothers’ perceptions of neighborhood disorganization for the specific monitoring strategies they use and how each of these strategies are related to youths’ alcohol use and delinquency. The sample consists of 415 mother–child dyads recruited from urban and suburban communities in Western New York state. Youths were between 10 and 16 years of age (56% female), and were mostly Non-Hispanic White and African American (45.3 and 36.5%, respectively). Structural equation modeling shows that mothers who perceive greater neighborhood problems use more rule-setting strategies, but report lower levels of knowledge of their children’s whereabouts. Knowledge of whereabouts is related to less youth alcohol use and delinquency through its association with lowered peer substance use, whereas rule-setting is unrelated to these outcomes. Thus, mothers who perceive greater problems in their neighborhoods use less effective monitoring strategies. Prevention programs could address parental monitoring needs based upon neighborhood differences, tailoring programs for different neighborhoods. Further, parents could be apprised of the limitations of rule-setting, particularly in the absence of monitoring their child’s whereabouts.     

The accuracy of simple ordinal scoring of tooth attrition in age assessment

Tooth wear is frequently used as a method of ageing skeletal remains. Fundamental to this method is the ability to measure the amount of tooth wear. The Brothwell chart based on the Miles method of ageing, uses simple ordinal scoring and is frequently used by archeologists. The purpose of the present investigation was to evaluate the accuracy of simple ordinal scoring in recording tooth wear and ageing skulls. A group of Chinese skulls of known age at death was used. The age range was from 16 to 60 years. A single score per molar tooth was used to record occlusal wear. The data were analysed by regression methods using BMDP statistical software. The results showed that molar tooth wear continues throughout the life of the individual. The first molar teeth wear significantly more quickly than do second molar teeth. Use of a simple ordinal score method for recording wear gives an inaccurate estimate of an individual skull's age at death with a very wide 95% confidence interval.     

Multiple-probe thermography for estimating the postmortem interval: I. Continuous monitoring and data analysis of brain, liver, rectal and environmental temperatures in 117 forensic cases

One hundred seventeen forensic postmortem cases have been studied under controlled conditions. In each case, temperatures of the brain, liver, rectum, and the environment were monitored over a period beginning shortly after death and ending up to 60 h postmortem. The four temperature measurements were recorded every 5 to 10 min using the Microwave Thermography System. Rectal and environmental temperatures were measured by electrical thermocouples while brain and liver temperatures were measured using microwave probes. Data acquisition, analogue-to-digital conversion (ADC), and data processing were provided by a microcomputer. The ADC technique is described and its problems are discussed. The data were then transferred to a mainframe computer for extensive curve-fitting and statistical analysis. The microcomputer-based ADC and data logging and acquisition were found to be accurate, fast, easy to implement, and useful for the field. The postmortem rate of human body cooling was found to be adequately represented by triple-exponential equations.
