Application of the discriminant analysis for the assessment of human somatotype using the long bones of extremities

Measurements were made on the basis of the osteological collection of the chair for anthropology, Moscow State University (70 cases), and on the basis of a series of skeletons (10 cases) from among burial places of the Novospassk Monastery (males aged above 18-20). Eleven sizes of Martin program (length, diaphysis circumference and epiphysis width) were fixed onto the humerus, radial, femoral and shin bones. Simultaneously, the development of the osseous relief elements in the above bones (a total of 18 signs in each skeleton) was evaluated by Fedosova program. The data was processed by SPSS. Discriminative analysis was used as a basis to work out a diagnostic model that can be used to determine a somatotype by the humerus, radial and femoral bones. The classification accuracy is 75%. The method should be applied in those cases, when the appropriate bones are available. If the available combination of bones is different from the above, the routine method is recommended for use, i.e. determination of a somatotype by the skeleton massiveness.     

Ossification of laryngeal structures as indicators of age

As the role of forensic anthropologists expands to the medical examiner setting, their expertise is being applied beyond the traditional dry skeletal material. In such scenarios radiographic techniques can be applied when maceration is not appropriate. This study explores the use of radiographic analysis of laryngeal structures for age-at-death determination. Isolated human laryngeal structures (n = 104) from individuals between the ages of 15 and 89 were removed at autopsy and radiographically examined. The cricoid and individual regions of the thyroid cartilage were scored according to degree of ossification, and the relationship between age and degree of ossification statistically examined. A previously published study on age-determination from thyroid ossification by Cerny was assessed for accuracy. The results of the study indicate that although a consistent sequence in the ossification of laryngeal structures exists, variations in timing does not permit narrow age range estimates. Consequently the method presented by Cerny is inaccurate and should not be used in the forensic setting.

Tornatzky, who was also professor of psychology and urban studies at Michigan State University, received his Ph.D. from Stanford University. He has co-authored nine books and monographs and more than 80 articles and papers.     

Troubled times for Canada's medical marijuana program

Health Canada finally produces a good marijuana crop, but its medical marijuana program is in a state of upheaval as it faces internal dissent regarding a crucial aspect of its mandate, as well as fundamental challenges from the courts. Meanwhile, the Justice Minister said that the government will introduce legislation to decriminalize the possession of small amounts of marijuana.     

Medical devices; reclassification of the topical oxygen chamber for extremities. Final rule

The Food and Drug Administration (FDA) is reclassifying the topical oxygen chamber for extremities (TOCE) from class III to class II. This device is intended to surround a patient's limb and apply humidified oxygen topically at a pressure slightly greater than atmospheric pressure to aid healing of chronic skin ulcers, such as bedsores. This reclassification is on the Secretary of Health and Human Services's own initiative based on new information. This action is being taken under the Federal Food, Drug, and Cosmetic Act (the FD&C Act) as amended by the Medical Device Amendments of 1976 (the 1976 Amendments), the Safe Medical Devices Act of 1990 (the SMDA), and the Food and Drug Administration Modernization Act of 1997 (FDAMA). Elsewhere in this issue of the Federal Register, FDA is announcing the availability of the guidance document entitled ``Class II Special Controls Guidance Document: Topical Oxygen Chamber for Extremities,' which will serve as the special control for this device.     

Methodology for the analysis of civil commitment detention times and costs

The authors expand their methodology for quantifying and comparing civil commitment processes by developing new formulas for the determination of the average commitment detention time and cost. They also examine the effects of specific changes in commitment procedures on the average detention time and cost. Using data from Oregon's civil commitment process, the authors present several examples of the practical application of their methodology and conclude with a discussion of its major administrative and research implications.     

Introducing Computed Tomography Standards for Age Estimation of Modern Australian Subadults Using Postnatal Ossification Timings of Select Cranial and Cervical Sites,

Contemporary, population‐specific ossification timings of the cranium are lacking in current literature due to challenges in obtaining large repositories of documented subadult material, forcing Australian practitioners to rely on North American, arguably antiquated reference standards for age estimation. This study assessed the temporal pattern of ossification of the cranium and provides recalibrated probabilistic information for age estimation of modern Australian children. Fusion status of the occipital and frontal bones, atlas, and axis was scored using a modified two‐ to four‐tier system from cranial/cervical DICOM datasets of 585 children aged birth to 10 years. Transition analysis was applied to elucidate maximum‐likelihood estimates between consecutive fusion stages, in conjunction with Bayesian statistics to calculate credible intervals for age estimation. Results demonstrate significant sex differences in skeletal maturation (p < 0.05) and earlier timings in comparison with major literary sources, underscoring the requisite of updated standards for age estimation of modern individuals.     

Investigating the impact of extended bar closing times on police stops for DUI

Researchers have often studied whether changes in the availability of alcohol impact associated problem behaviors like drunk driving. In July of 2003, the state of Minnesota approved legislation to extend by one hour the closing time for eating and social establishments that serve alcohol. This study utilized a time-series model to examine the impact of the extended closing time on the number of police stops for DUI in one jurisdiction in Minnesota. While results of the time-series indicated that there was a significant increase in the number of police stops for DUI following this legislative change, incident-specific analyses suggested that this increase might have been largely a result of increased proactive responses by local police. Implications and suggestions for future research are discussed.

The Australian Prisons Census: Estimating remand times

By applying a renewal theory model to data from the Australian Prisons Census, we estimate the number of remand receptions at prisons and the mean and median remand times served by prisoners during the period 1982–1990. We conclude that despite the general increases in court delays, and despite a large increase in the remand reception rate between 1982 and 1990, remand times have been largely unaffected, with the median remand time for 1990 being 1.7 weeks. Comparisons are made with official figures for various states and with figures for Canada and England/Wales.
