DNA recovery after sequential processing of latent fingerprints on copy paper

Forensic examiners must determine whether both latent fingerprint development and DNA profiling can be performed on the same area of an evidence item and, if only one is possible, which examination offers the best chance for identification. Latent fingerprints can be enhanced by targeting different components of fingerprint residues with sequential chemical treatments. This study investigated the effects of single-reagent and sequential latent fingerprint development processes on downstream DNA analysis to determine the point at which latent fingerprint development should be stopped to allow for DNA recovery. Latent fingerprints deposited on copy paper by one donor were developed using three sequential processes: 1,8-diazafluoren-9-one (DFO) → ninhydrin → physical developer (PD); 1,2-indanedione-zinc (IND-Zn) → ninhydrin → PD; and IND-Zn → ninhydrin → Oil Red O (ORO) → PD. Samples were examined after the addition of each chemical treatment. DNA was collected with cotton swabs, extracted, quantified, and amplified. DNA yields, peak heights, number of alleles obtained, and percentage of DNA profiles eligible for CODIS upload were examined. DNA profiles were obtained with varying degrees of success, depending on the number and type of treatments used for latent fingerprint development. The treatments that were found to be the least harmful to downstream DNA analysis were IND-Zn and IND-Zn/laser, and the most detrimental treatments were DFO, DFO/laser, and PD. In general, as the number of treatments increase, the opportunities for DNA loss or damage also increase, and it is preferable to use fewer treatments when developing latent fingerprints prior to downstream DNA processing.     

Cuba in Transition? The Civil Sphere's Challenge to the Castro Regime

This article assesses how much the emergence of civil society and private market activities are challenging Cuba's ruling communist regime. The assessment is based on a conceptualization of a "civil sphere," constituted by civil society and private market activities (or the "second economy"), and how this affects democratic transitions from state-socialist societies, using Cuba as a case study. Examining the multiple sectors at play reveals an increasingly organized and vocal opposition, but one hampered by continued government repression. Considering several theoretical and historically possible scenarios, this study concludes that under current conditions, the civil sphere's significant challenge is still not enough for a regime change in the Cuban state.     

Parent-child attachment working models and self-esteem in adolescence

The degree of continuity over time in the quality of parent-child attachments and the relationship between these attachments and current self-esteem was investigated. Subjects were 218 nonparent college students. The attachment working model styles were determined by modified versions of two attachment measures. Epstein's Mother-Father-Peer Scale of 1983 yielded separate scores for independence-encouraging and acceptance, and Hazan and Shaver's 1987 Rocky Mountain Survey indicated secure, avoidant, or ambivalent attachment patterns. Self-esteem was measured by Coopersmith's Self-Esteem Inventory of 1967. Data collected indicated support for Bowlby's 1988 theory of continuity over time of attachment. Self-esteem was related to both childhood and adolescent working model styles of attachment and to the dimensions of independence-encouraging and acceptance. The two attachment measures were related. Subjects who classified their parent-child attachment as secure rated their parents as high in independence-encouraging and acceptance.This paper is based, in part, on the first author's thesis for the M.A. degree at Georgia Southern University. Portions of this paper were presented at the Biennial Conference on Human Development, Atlanta, Georgia, April 1992.Received M.A. in psychology from Georgia Southern University in 1991.

Corporal punishment: Normative data and sociological and psychological correlates in a community college population

Community college students (N=170) were surveyed regarding the intensity and frequency of methods of corporal punishment they have received and the persons administering the punishment. Results indicate that corporal punishment is a normatively used method of behavioral management. Males reported receiving a greater amount of corporal punishment, especially from their fathers. Overall, those who received a high amount of corporal punishment reported lower grades and a significantly greater number of problems, such as aggression, delinquency, depression, and anxiety. These findings are cause for concern and intervention.Received Ph.D. in psychology from Tufts University. Main research interests are sex-role development and personality development.Received C.A.S. in counseling from Harvard University. Main research interests are battered wives and incest.     

Fatal bupivacaine intoxication following unusual erotic practices

A fatal drug overdose is described which involved unusual erotic practices. A 54-year-old male was discovered supine on the floor surrounded by sexual paraphernalia, syringes, and medications including three empty bottles of bupivacaine. Acute and chronic injection sites of the external genitalia with contusions, scarring, focal necrosis, and calcification were present at autopsy. Toxicology revealed femoral blood, heart blood, and vitreous bupivacaine concentrations of 3.8, 2.8 and 1.3 mg/L, respectively. The urine bupivacaine concentration was 11.4 mg/L. The cause of death was attributed to bupivacaine intoxication and the manner of death was accidental.     

Distributing Adventitious Resources: The Effects of Relationship and Grouping

This study examines the effect of two variables—relationship and grouping—on the distribution of resources which are unearned, or adventitious. Strangers and acquaintances made decisions about the distribution of an adventitious resource either as individual decision makers or as members of a small group. Results indicate that acquaintances were more likely to share the resource than were strangers, and that group members were more likely to share than were individual allocators. Equality received the highest overall rating as a norm for distributing the adventitious resource. At the same time, subjects expected allocators to keep the resource instead of applying an equality distribution norm.     

Doctors and AIDS

Just a year ago most authorities considered the chances of patients contracting AIDS from doctors and other healthcare workers a virtual impossibility. But last week a Florida woman who got AIDS from her dentist lay near death, and two Minneapolis physicians admitted they had treated hundreds of patients since being diagnosed with the virus. Although doctors are at far greater risk than patients, the Minneapolis cases renewed the debate over the right of sides to know each other's HIV status.
