The technique of isoelectric focusing in ultra-thin polyacrylamide gels as a method of typing human red cell phosphoglucomutase (PGM1) has been studied. Typing was possible without the samples attaining true equilibrium focusing conditions. The isozyme patterns so obtained were clearly defined and free from distortion. The importance of assessing relative band intensities when interpreting the isozyme patterns is discussed. Our experience of using the technique to analyse casework material is described. 相似文献

Although politicians, police, and others have often advocated the expansion of police employment in the effort to control crime, the empirical relationship between police employment and crime rates has seldom been systematically explored. This study incorporates variables which are causally related both to crime and police employment roles for the 252 northern and northeastern suburbs for which police employment and crime data are available for 1970–1972. Separate analyses of violent and property crime are undertaken, incorporating data on police employment as a causally related variable along with several other determinants of crime identified in earlier studies. The analysis suggests that police employment and crime rates are reciprocally related, and that these relationships offer more support for a “labeling” than a “deterrence” perspective. 相似文献

A discrete nebulisation technique has been developed for the multi-element analysis of 100-μl solution droplets by inductively coupled plasma-optical emission spectrometry (ICP-OES). The technique increases analytical speed and uses very small solution volumes with only a slight degradation in detection limits when compared to continuous solution introduction.To evaluate its suitability in casework, small alloy fragments were produced by cutting with a hacksaw, sample division and filing. The analysis of fragments from two different brasses indicated that quantitative data could be obtained from fragments as small as 10 μg. The accurate determination of lead, a non-homogeneous constituent of leaded brasses, required sample sizes an order of magnitude greater. Analysis of an alloy of fine grain structure (copper-nickel) demonstrated that quantitative data could be obtained from samples weighing a few micrograms or less. 相似文献

In recent times, juvenile rehabilitation has been attacked both by liberals seeking to insert greater due process rights and protections into the juvenile justice system and by conservatives calling for more stringent handling of serious youthful offenders. The apparent pervasiveness of this attack raises the question, Is the philosophy of child saving dead? Data drawn from a survey conducted in Illinois suggest, however, that juvenile rehabilitation continues to receive support both from the public and from various groups associated with criminal justice practice and policy making. At the same time, there is also support for the notion that young criminals are responsible for their actions and are currently being treated too leniently by our courts. Finally, child saving is embraced most firmly by judges, lawyers, correctional administrators, and prison inmates and least strongly by legislators, prison guards, and the general public. 相似文献
