Laser desorption/ionization time-of-flight mass spectrometry of triacylglycerols and other components in fingermark samples

The chemical composition of fingermarks could potentially be important for determining investigative leads, placing individuals at the time of a crime, and has applications as biomarkers of disease. Fingermark samples containing triacylglycerols (TAGs) and other components were analyzed using laser desorption/ionization (LDI) time-of-flight mass spectrometry (TOF MS). Only LDI appeared to be useful for this application while conventional matrix-assisted LDI-TOF MS was not. Tandem MS was used to identify/confirm selected TAGs. A limited gender comparison, based on a simple t-distribution and peaks intensities, indicated that two TAGs showed gender specificity at the 95% confidence level and two others at 97.5% confidence. Because gender-related TAGs differences were most often close to the standard deviation of the measurements, the majority of the TAGs showed no gender specificity. Thus, LDI-TOF MS is not a reliable indicator of gender based on fingermark analysis. Cosmetic ingredients present in some samples were identified.     

The use of SEM/EDS analysis to distinguish dental and osseus tissue from other materials

With increasing frequency, relatively small, fragmentary evidence thought to be osseous or dental tissue of human origin is submitted to the forensic laboratory for DNA analysis with the request for positive identification. Prior to performing DNA analysis, however, it is prudent to first perform a presumptive test or "screen" to determine whether the questioned material may be eliminated from further consideration. When material is shown not to be consistent with bone/teeth, DNA testing is not performed. When such determinations cannot be made from gross morphological features, elemental analysis can be indicative. This presumptive test is made possible by applying scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS) in conjunction with an X-ray spectral database recently developed by the FBI laboratory. This database includes spectra for many different materials including known examples of bone and tooth from many different contexts and representing the full range of taphonomic conditions. Results of SEM/EDS analysis of evidence can be compared to these standards to determine if they are consistent with bone and/or tooth and, if not, then what the material might represent. Analysis suggests that although the proportions and amounts of calcium and phosphorus are particularly important in differentiating bone and tooth from other materials, other minor differences in spectral profile can also provide significant discrimination. Analysis enables bone and tooth to be successfully distinguished from other materials in most cases. Exceptions appear to be ivory, mineral apatite, and perhaps some types of corals.

Location and other correlates of campus crime

Crime and security are major issues on a number of college campuses in the United States, yet little criminology research has been aimed at the campus setting. This article explores whixh aspects of the campus profile seem to contribute, or at least relate, to high levels of campus crime. A regression of crime rates on dimensions of the campus profile uncovered a number of correlates (specifically, measures of campus size and scholastic quality) in our sample of 222 colleges and universities. Somewhat surprisingly, the location of a campus—be it in an urban or a rural setting—had no impact on the level of its crime problem, though a slight influence on crime mix (proportion of crimes that are violent) was found.

浅议记名提单下承运人的交货义务及相关法律问题

记名提单是一种不可流转的海运单证,也就不具备可流转海运提单的物权凭证效力。同时,作为海上运输合同的证明,记名提单对于承运人在目的港的交货对象于运输合同缔结之初就已经确定,因此承运人在记名提单下的交货义务并不以收货人持有正本提单为必要,承运人只要是向记名收货人交付货物就已经构成了运输合同下的适当交付,承运人也不应对此承担无单放货的民事责任。     

Race and treating other people's children as adults

Juvenile offenders are sometimes transferred to a criminal court where they may stand trial as adults. The rationale for this current trend cannot be justified based on evidence from developmental psychology, the evidence of consistent positive effects for particular intervention strategies, and ethical arguments for justification of punishment. The rationale in actuality reflects the selective manipulation of the alternative conceptions of young people as dependent and vulnerable or as autonomous and responsible to continue to justify policies that entail cultural and racial discrimination. Discretionary decisions at various stages of the justice process amplify racial disparities as minority youths proceed through the system and result in more severe dispositions than for comparable White youths.
