Dermestes maculatus (Coleoptera: Dermestidae) development under fluoxetine effect using two drug administration models

Fluoxetine is a selective serotonin reuptake inhibitor, commonly used for the treatment of a variety of psychopathological conditions. As such, fluoxetine may be expected to appear in clinical and forensic cases. Dermestes maculatus De Geer (Coleoptera: Dermestidae) has been recognized as a relevant component of the insect fauna associated with decomposing human and animal remains. Experiments were conducted to study the effect of fluoxetine on developing D. maculatus using two‐drug administration models: a non‐living animal model (pork muscle) and a living one (Sus scrofa L. pigs). We assessed the duration of immature stages and total life cycle, as well as morphological parameters (body length, cephalic width, and weight). The effect of fluoxetine was studied at an overdose concentration: In the non‐living animal model the drug was mixed with macerated pork muscle (2000 mg/kg) and in the living animal model, pigs were given the drug orally (833 mg/kg). A control was used for each model. Daily observations were performed from the beginning to the end of the experiments. GC‐MS was used for drug detection and quantification. There were no statistically significant differences in the duration of immature stages, life cycle, larval mortality, morphological parameters, or sex ratio, between treatment and control, regardless of the drug administration model. Given that fluoxetine had no detectable effect on the development of D. maculatus, detection of this drug in forensic situations would not compromise the accuracy of PMI estimations.     

Relationship Religiosity,Adult Attachment Styles,and Courtship Violence Experienced by Females

This study assesses the association between adult attachment styles, religiosity, and courtship violence as experienced by females. The sample was composed of 299, 18 to 24-year-old females attending junior level Human Development and Family Studies courses at a midwestern state university. Statistical analyses evaluated interactional effects and mean-level differences for both victimization and perpetration of courtship violence. Additionally, structural equation models were generated. Results indicate significant relationships between adult attachment styles and religiosity on reports of victimization from intimate partners. In general, the results suggest that females with low religiosity and insecure attachment styles report experiencing more courtship violence than females reporting high religiosity and secure attachment styles. The analyses also provide support for a multidimensional conceptualization of religiosity. Indicators of `relationship' religiosity were more strongly linked to lower reports of courtship violence than personal and private relationship measures. The findings suggest that future studies evaluating the effects of religiosity on courtship violence should include measures of `relationship’ religiosity.     

Chemical profiling of heroin recovered from the North Korean merchant vessel Pong Su

Heroin samples, seized from the North Korean merchant vessel Pong Su in Australian waters, were analyzed to determine geographic origin. Duplicate samples were analyzed by the National Measurement Institute's Australian Forensic Drug Laboratory and the United States Drug Enforcement Administration's Special Testing and Research Laboratory. Alkaloid ratios were determined by both liquid chromatography-diode array detection (LC-DAD) and capillary electrophoresis-diode array detection (CE-DAD) techniques. Acid/neutral manufacturing by-products were determined by solvent extraction followed by gas chromatography-mass spectrometry (GC-MS). Solvents, trapped in the heroin particles during manufacture, were detected by both static headspace GC-MS and purge and trap GC-MS. The alkaloid ratios obtained were consistent with heroin of a Southeast Asian (SEA) origin and principal component analysis of the alkaloid results demonstrated the presence of at least four subgroupings within the seizure. The solvent analysis detected diethyl ether and ethyl acetate, solvents typically seen in SEA heroin. However, the acid/neutral analysis revealed compounds not normally seen in heroin of a SEA origin. Furthermore, sterol-like molecules, always detected in the acid/neutral analysis of SEA heroin, were absent from the Pong Su samples. The Pong Su heroin, although similar to SEA heroin, has sufficient differences to classify it as having an unknown origin at the time of this writing.     

DNA databanks: law enforcement's greatest surveillance tool?

All fifty states have laws requiring the collection of DNA samples from certain classes of criminals. Genetic profiles are gleaned from these samples and entered into DNA databanks, after which they then can be accessed by law enforcement personnel and others. DNA forensic technologies can be used to identify criminal offenders, but they can also be used in ways that reveal health and other personal information about the target and even about his or her relations. Moreover, the rapid introduction of ever-changing types of DNA forensic techniques creates a potential for error. Such errors may wrongly implicate some individuals for a crime and may wrongly exculpate others. This Article examines weaknesses in state DNA databanking laws regarding the protection of genetic privacy and imposition of quality assurance mechanisms and suggests policies which state legislatures should incorporate into the state DNA databanking scheme.     

Inmate family functioning

Two-hundred-nine noninmates and 169 inmates completed questionnaires that assessed retrospective perceptions of 12 dimensions of family life and one overall assessment of quality of family life. Between the inmates and noninmates, means for all dependent variables differed significantly except for self-reliance; however, meaningful eta-squares were found only for dimensions of bridging, disengagement, and quality of life. Among the independent-samples t tests for gender, eta-squares were not meaningful. Implications for family life interventions in correctional facilities are suggested.
