Variability of bodily measures of normally dressed people using PhotoModeler Pro 5

Photogrammetry is used in forensic science to help identify perpetrators from crime scenes by way of surveillance video, but the reproducibility of manually locating hidden body-points such as the joints remains to be established. In this study, we quantified the inter- and intra-observer variability of bodily measures of clothed individuals in two different poses and examined whether body segment lengths could be used to distinguish between people of similar stature. Stature was reproduced within +/-1.5 cm in both the intra- and inter-observer study. Segment lengths were best reproduced when flexion in the joints was present in the intra-observer study, but only the length of the trunk could be used to distinguish between people of similar height. The reproducibility between the two poses was low. Other measures than stature should be used with caution and with the perpetrator and suspect in the same pose. Consistent guidelines for locating body-points should be developed.     

An estimation of the lag structure of the economic impact of an oil embargo

A number of economic models have been used to estimate the economic losses resulting from oil embargoes, but they have not been able to provide good answers about how quickly an economy would recover once the embargo was over. This study uses a phase lag analysis to estimate the lag structure of an embargo, and concludes that the major economic effects should be expected to disappear about six weeks after an embargo ends.The views expressed in this paper are those of the authors and do not necessarily reflect the position of the Department of Energy.

Parental problem-solving skills and child behavior problems: A comparison of physically abusive,neglectful, clinic,and community families

Failure to solve problems related to parenting and other aspects of daily living is hypothesized to result in frustration or inability to cope, and lead to deviant parental behavior such as aggression or neglect. The present investigation provided support for a procedure for measuring parental problem-solving skill and compared the problem-solving abilities and child behavior problems of maltreating and nonmaltreating parents. Subjects were 40 parents with at least one child between the ages of three and twelve. Subjects were assigned to one of four groups: (a) physically abusive parents (n = 9); (b) neglectful parents (n = 9); (c) nonmaltreating clinic parents seeking help for child behavior problems (n = 11); and (d) nonmaltreating, non-help-seeking community parents (n = 11). Abusive and neglectful parents were deficient in problem-solving skill as compared to clinic and community parents, yet there were many similarities in parental reports of child behavior problems for maltreating and nonmaltreating parents. Parental problem-solving skill did not correlate significantly with parental ratings of child behavior problems.
