Deterrence and the tipping effect

Previous research has focused on certaintyznty of punishment as one. factor. upon which any dzterrent effect of punishment might be contingent and Auggested that it must reach a critical tipping level before the deterrent effect becomes evident. Using data on index crimes and clearance. rates for. Virginia cities and counties, bupport was found for both the. deterrent effect and the exlstenee of a tipping level. Attention was directed towand a more precise specification of the form of the tipping effect, suggesting that there is a single critical tipping level and that it occurs at a relatively low level of certainty of punihment.     

Hypervariable regions of DNA for parentage testing and individual identification

Four kinds of DNA probes that recognize hypervariable regions (HVR) were studied for parentage testing and individual identification. Allele frequencies and their confidence intervals among unrelated Japanese individuals were obtained. Codominant segregation of the polymorphism was confirmed in family studies. Two a priori probabilities were calculated for each HVR locus: the exclusion probabilities for an alleged father/mother/child trio and for an alleged parent/child duo, and the probabilities of matching of genotypes of two unrelated individuals or two siblings. The ease of availability of the probes and their highly discriminating polymorphic patterns mean they could be very useful for forensic purposes.     

The shielding capacity of the standard military flak jacket against ballistic injury to the kidney

An animal model was designed to evaluate the ability of the standard military flak jacket to protect the kidneys from direct ballistic trauma. Yorkshire swine were anesthetized and their flanks were protected by flak jackets. Ballistic insults ranging from a low-velocity handgun to a high-velocity rifle were evaluated. The results demonstrate that a flak jacket provides adequate protection against low- and mid-velocity projectiles since none of the animals from this group had evidence of internal trauma and because only minor superficial surgical attention would have been required. Survivability in each case was considered to be excellent. The flak jacket failed to provide any protection against several types of high-velocity bullets. These weapons caused severe internal injury to the genitourinary system as well as to other major organ systems. Survival would have been unlikely.     

The relationship of perceptions and emotions to behavior in the face of collective inequality

The present experiment investigated the role of emotions and perceptions in determining the overt behavior of disadvantaged group members. Three limitations to the existing psychological research are presented as a possible reason for the present inability to describe a consistent relationship between the emotions and perceptions of those faced with intergroup inequalities and their subsequent actions. The present experiment attempted to address these limitations by employing a laboratory paradigm in which subjects actually engage in overt behavior. As well, a broader array of emotions and perceptions were assessed and subjects were offered a variety of behaviors from which to choose. The findings point to a relatively strong relationship between emotions and perceptions on the one hand, and overt action on the other. Feelings of frustration and anger, the perception of one's personal treatment as satisfactory and just, and hope of future improvement of one's position combined to discriminate between subjects who accepted their disadvantaged position, those who took normative forms of action, those who reacted in an individual nonnormative way, and those who chose collective nonnormative behavior.     

An infant fatality involving ajmaline

An infant fatality following accidental ingestion of ajmaline is described. Ajmaline was determined by thin-layer chromatography and infrared spectrophotometry, and quantitated by high performance liquid chromatography. The ajmaline concentration in blood was 5.5 micrograms/mL. The toxicological data relevant to the interpretation of case findings are presented.
