Determination of group affiliation of isolated spermatozoa after separation from squamous epithelium cells

Outlined in the paper are outlooks for determining a group affiliation of sperm in traces, left in material evidence, within forensic biological expertise. A technique is suggested to separate the spermatozoids from the vaginal epithelium cells--it has been used up to now in genetics alone. The method involves the available reagents and does not need any extra training. Its elaboration and introduction would resolve one of the most often-encountered issues set by the investigating office.     

Lineup Identification by Children: Effects of Clothing Bias

This study examined effects of clothing cues on children's identification accuracy from lineups. Four- to 14-year-olds (n = 228) saw 12 video clips of individuals, each wearing a distinctly colored shirt. After watching each clip children were presented with a target-present or target-absent photo lineup. Three clothing conditions were included. In 2 conditions all lineup members wore the same colored shirt; in the third, biased condition, the shirt color of only one individual matched that seen in the preceding clip (the target in target-present trials and the replacement in target-absent trials). Correct identifications of the target in target-present trials were most frequent in the biased condition, whereas in target-absent trials the biased condition led to more false identifications of the target replacement. Older children were more accurate than younger children, both in choosing the target from target-present lineups and rejecting target-absent lineups. These findings suggest that a simple clothing cue such as shirt color can have a significant impact on children's lineup identification accuracy.     

Reliability of Sexually Violent Predator Civil Commitment Criteria in Florida

The present study investigated the reliability of Sexually Violent Predator (SVP) civil commitment criteria under Florida's Jimmy Ryce Act. The purpose of the study was to determine if, independently, 2 evaluators would reach the same conclusions about the same client (n = 295). According to civil commitment criteria outlined by the United States Supreme Court (Kansas v. Hendricks, 1997), SVPs must display a mental abnormality predisposing them to sexual violence and a likelihood of future sexual violence. The interrater reliability of 8 DSM-IV diagnoses applied by evaluators to determine whether a client has a "mental abnormality that predisposes him to sexual violence" was found to be poor to fair (kappa = .23 to . 70). The interrater reliability of risk assessment instruments used to determine "likelihood of reoffense" was good (ICC = .77 to .85). The recommendations made by evaluators regarding whether or not to refer a client for civil commitment demonstrated poor reliability (kappa = .54). Implications for practice and policy are explored.     

<Emphasis Type="Italic">Commentary</Emphasis>: A Critical Review of Published Competency-to-Confess Measures

The development of standardized assessments for competency-to-confess evaluations has remained largely neglected for the last several decades. Groundbreaking research was conducted on Miranda waivers during the late 1970s, but researchers have failed to sustain programmatic research. This critical review focuses on four published Miranda measures (Comprehension of Miranda Rights, Comprehension of Miranda Rights-Recognition, Comprehension of Miranda Vocabulary, and Function of Rights in Interrogation). When evaluated by contemporary standards, the validation of these measures is very limited. Major improvements are needed for interrater reliability, test–retest reliability, content validity, construct validity, and criterion-related validity.     

Priming Unconscious Racial Stereotypes About Adolescent Offenders

Two studies examined unconscious racial stereotypes of decision makers in the juvenile justice system. Police officers (Experiment 1) and juvenile probation officers (Experiment 2) were subliminally exposed to words related to the category Black or to words neutral with respect to race. In a presumably unrelated task, officers read 2 vignettes about a hypothetical adolescent who allegedly committed either a property crime (shoplifting from a convenience store) or an interpersonal crime (assaulting a peer). The race of the offender was left unstated and the scenarios were ambiguous about the causes of the crime. Respondents rated the hypothetical offender on a number of traits (e.g., hostility and immaturity) and made judgments about culpability, expected recidivism, and deserved punishment. They also completed a self-report measure of conscious attitudes about race. As hypothesized, officers in the racial prime condition reported more negative trait ratings, greater culpability, and expected recidivism, and they endorsed harsher punishment than did officers in the neutral condition. The effects of the racial primes were not moderated by consciously held attitudes about African Americans. The implications of the findings for racial disparity in the juvenile justice system and for changing unconscious stereotypes were discussed.     

Cerebrospinal fluid analysis in fatal thallium poisoning: evidence for delayed distribution into the central nervous system

The neurologic manifestations of thallium poisoning include a severely painful ascending peripheral neuropathy, autonomic dysfunction, cranial nerve abnormalities, and a toxic encephalopathy. Although thallium has a short half-life, these neurologic manifestations commonly progress, even as the blood concentration of thallium decreases. This suggests either that thallium persists in neuronal tissues or that it initiates an injury cascade that takes time to fully manifest. As the latter mechanism is consistent with many toxin exposures, the concept of a central nervous system reservoir for thallium is often discounted. A recent case provided a unique opportunity to evaluate this possibility. A 48-year-old man was acutely and chronically thallium poisoned by his common-law wife. During his initial exposures, only gastrointestinal symptoms manifested. Following an acute ingestion, hospitalization was required. Over 3 days, his symptoms rapidly progressed from a severely painful neuropathy to slurred speech, ptosis, confusion, coma, respiratory insufficiency, and death. Because of considerations of alternative diagnoses, 2 lumbar punctures were performed, one on admission and another on the day of his death. Serum thallium concentrations obtained from stored blood samples were paired with spinal fluid concentrations from the same days. On day 1, serum and spinal fluid concentrations were 8700 mu/L and 1200 mu/L, respectively. On day 3, although the serum concentration had fallen to 7200 mu/L, the spinal fluid concentration had increased to 2100 mu/L. This case provides evidence to support the hypothesis that thallium distributes into the central nervous system more slowly than the blood compartment, and this may in part account for the progression of neurologic findings in the setting of decreasing serum concentrations.     

States and the politics of incrementalism: health policy in Wisconsin during the 1990s

Wisconsin officials during the 1990s seemed poised to enact innovative and comprehensive health care reform. During that era, an ambitious, popular, and reform-minded governor led the state. The state had an unusually professional legislature. The state's economy was strong. Even with these advantages, however, the report card on the state's efforts is mixed. The state enacted a fairly modest set of reforms that were financed largely by the federal government and subject to extensive federal oversight. The Wisconsin story thus seems to be about the politics of incrementalism. But while critics of incrementalist politics point out that the number of uninsured continues to grow, the catalytic federalism witnessed in Wisconsin in the 1990s may well be the best model for implementing health care reform.
