The RECON typology of stalking: reliability and validity based upon a large sample of North American stalkers

A new typology of stalking, RECON (relationship and context-based), is proposed, based upon the prior relationship between the pursuer and the victim, and the context in which the stalking occurs. The static typology yields four groups: Intimate, Acquaintance, Public Figure, and Private Stranger. The typology was tested on a large (N = 1005) nonrandom sample of North American stalkers gathered from prosecutorial agencies, a large police department, an entertainment corporation security department, and the authors' files. Interrater reliability for group assignment was 0.95 (ICC). Discriminant validity (p < 0.01) was demonstrated on a variety of demographic, clinical, pursuit, threat, and violence characteristics among and between groups. Findings confirm and extend the work of other researchers, most notably the very high risk of threats and violence among prior sexually intimate stalkers, the very low risk of threats and violence among public figure (celebrity) stalkers, and the negative relationship between stalking violence and psychosis.     

Evaluating the accuracy and precision of cranial morphological traits for sex determination

Sex determination is a key analysis that forensic anthropologists perform in order to construct a biological profile of human remains. The techniques used in forensic investigations must meet the Mohan or Daubert criteria, for admissibility in a court of law. In this study, the precision and accuracy of 21 morphological characteristics of the skull were tested on a modern sample of 50 adult crania of European White ancestry. The following craniofacial features are identified as high-quality traits, defined by intraobserver error or=80%: mastoid size, supraorbital ridge size, general size and architecture, rugosity of the zygomatic extension, size and shape of the nasal aperture, and gonial angle. Ninety-six percent accuracy and 92% precision were achieved using 20 traits in combination. Fisher's exact probability tests revealed no significant differences (p=0.05) in the levels of precision or accuracy between age categories. Sex-related bias in accuracy was found for the following cranial features: ramus symphysis (p=0.009), zygomatic extension (p=0.0016), and occipital markings (p=0.0013). These traits demonstrated a greater tendency to be scored male than female.     

Validation of the Cozart Amphetamine Microplate EIA for the analysis of amphetamines in oral fluid

The purpose of this study was to determine the performance characteristics of the Cozart Amphetamine Microplate EIA for detecting amphetamine in oral fluid. Oral fluid samples were collected using the Cozart RapiScan Collection System from 135 volunteer donors from drug treatment clinics. A further 35 oral fluid samples were collected from volunteer donors who were not drug users. The samples were analyzed in the laboratory using the Cozart Amphetamine Microplate EIA and confirmed using gas chromatography-mass spectrometry (GC-MS). The samples were stored frozen until analysis by GC-MS. The intra-assay precision for the Cozart Amphetamine Microplate EIA for amphetamine in oral fluid over forty assays was 2.74-7.1% CV (within assay) and 3.4-7.0% CV (within day). A total of 78 samples were positive for various amphetamines and related designer drugs. The Cozart Amphetamine Microplate EIA, using a cutoff of 45 ng/ml amphetamine equivalents in neat oral fluid, had a sensitivity of 91.7+/-3.3% and a specificity of 95.9+/-1.9% versus GC-MS using a cutoff of 30 ng/ml. A series of potential adulterants of oral fluid were evaluated and shown not to alter the outcome of the test result.     

Use of aquatic insects in determining submersion interval

Although its potential is great, the use of aquatic insects in determining submersion intervals at death-scene investigations has not been exploited in the past. Aquatic environments have no known true specific indicator species, as do terrestrial habitats. However, aquatic environmental studies show that organisms may colonize a substrate dependent on factors such as size, position, exposure to current, water temperature, current speed, water depth, the presence of algal communities, or detritus. Certain aquatic insects such as the chironomid midges (Diptera, Chironomidae), and the caddisflies (Trichoptera), are capable of colonizing immersed bodies; and with the known biology of a specific species of insect for a certain geographic area, time intervals of submersion can be established.     

Returning to Delinquency: Factors Effecting the Survivorship of Juvenile Shoplifters

This article examines a program designed to provide a family court with a means of lessening the probability that youths on probation for shoplifting will return to criminal behavior. A single staff member within the family court screened possible participants, all of whom were defined as first-time shoplifting offenders and had been assigned to formal or informal probation. Each individual was invited to participate in a four-hour clinic, during which time the realities and possible consequences of shoplifting were explained. If they were able to successfully complete six months of supervised probation, then only the administrative record remained; the conviction itself was expunged. Over a period of nine months, a total of 154 juveniles were invited; however, only 100 actually took part in all facets of the program. A total of 30 clinic attendees and 14 nonparticipants were excluded from the present analysis, owing to missing data, or the fact that at the time of follow-up, they were legally classified as adults. The prior and subsequent court contacts of 110 subjects are reviewed. While less than 3% of either group had subsequent shoplifting arrests, nearly 26% of the program group and 35% of the nonparticipants were rearrested. Factors associated with long-term success and failure are examined. Possible reasons for these observations are discussed, with specific grounding in the shoplifting literature and the concepts of juvenile diversion and “net-widening.”     

The effects of stealing thunder in criminal and civil trials

The effectiveness of a persuasion technique referred to asstealing thunder was assessed in two simulated jury trials. Stealing thunder is defined as revealing negative information about oneself (or, in a legal setting, one's client) before it is revealed or elicited by another person. In Study 1, 257 college students read or heard one of three versions of a criminal assault trial in which a damaging piece of evidence about the defendant was absent (no thunder), brought up by the prosecutor (thunder), or brought up by the defense attorney and repeated by the prosecutor (stolen thunder). In Study 2, 148 college students heard a civil negligence trial in which damaging evidence about the key plaintiff's witness was absent (no thunder), brought up by the defendant's attorney (thunder), or brought up by the witness himself (stolen thunder). In both studies, stealing thunder significantly reduced the impact of the negative information. A path analysis of the processes underlying the effect suggested that verdicts were affected because of enhanced credibility.Often a difficult decision in opening statements is whether, and if so how, to volunteer weaknesses. This involves determining your weaknesses and predicting whether your opponent intends to use them at trial. There is obviously no point in volunteering a weakness that would never be raised at trial. Where, however, that weakness is apparent and known to the opponent, you should volunteer it. If you don't, your opponent will, with twice the impact. (Mauet, 1992, pp. 47–48)We would like to thank Michelle Cox, Gim Koay, Dana Koay, and Ralph Mueller for their helpful input.
