Portuguese population and paternity investigation studies with a multiplex PCR--the AmpFlSTR Profiler Plus

A Portuguese Caucasian population of 146 unrelated individuals was studied. DNA samples were amplified by multiplex PCR for D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317 and D7S820 using the AmpFlSTR Profiler Plus PCR Amplification Kit (Perkin-Elmer). All loci met Hardy-Weinberg expectations. Forensic statistical parameters were according to those obtained by other authors. Statistical differences were observed concerning three loci when comparing the Portuguese Caucasian population and an Italian Caucasian population, although these differences mainly concern the less frequent alleles. Eighty-three paternity investigation cases were analysed. Exclusions in between three and nine loci were observed in all the 23 exclusion cases obtained. Most of the non-exclusion cases had probability of paternity > 99.9%. Two cases with an isolated genetic incompatibility between the alleged father and the child were detected, which may indicate probable mutation cases. These results demonstrate that the AmpFlSTR Profiler Plus is a suitable multiplex for paternity investigation in the Portuguese population.     

Radiologically determined DMF index variations for forensic age estimation of young adults

The eruption and mineralization of third molars are the main criteria for dental age estimation of living people involved in criminal proceedings. Since the development of third molars is usually completed by the age of 19 or 20 years, this feature cannot be used to ascertain whether a person has attained the forensically relevant age of 21 years. This study examined whether the DMFT index or the third molar DFT index could supply reliable information enabling conclusions to be drawn about whether a person has reached the age of 21. To this end, 650 conventional orthopantomograms of German subjects aged 18 to 30 years were evaluated. The DMF index variations considered were found to be unsuitable for determining whether a person is over 21 because they displayed a weak correlation with age and considerable individual scatter. A high indicative value can only be attributed to a third molar DFT index of 4, although this is rarely observed in the relevant age group. An X-ray examination of the medial clavicular epiphyseal cartilage is, therefore, strongly recommended when assessing whether a person has attained 21 years of age.     

Selective Sexual Harassment: Differential Treatment of Similar Groups of Women Workers

If male workers categorize different groups of women coworkers and, subsequently, treat them differently, the experiences of women from one of these groups would not be indicative of the experiences of women from another group. When this different treatment involves hostile environment sexual harassment of one group, but not the other, then the law must recognize the possibility of "selective sexual harassment." Without this understanding of the nuances of the workplace dynamics, a court could mistake the women of the unharassed group as representing "reasonable women" and the women of the harassed group as simply oversensitive. This paper draws on empirical data to demonstrate such a situation and advocates for a version of the "reasonable victim" standard to facilitate a closer analysis of hostile environment sexual harassment suits.     

Suicide risk in outpatients with specific mood and anxiety disorders

The present study examined the relationships between specific anxiety, mood disorders, levels of hopelessness, and suicide ideation. The sample consisted of 606 outpatients recruited from several psychiatric settings. It was found that dysthymia was significantly associated with hopelessness. Patients presenting major depressive episode with higher anxiety symptoms had significantly increased scores on the hopelessness scale. Major depressive episode and bipolar disorder, but not dysthymia, were significantly associated with higher levels of suicide ideation. Increased levels of anxiety symptoms in patients with dysthymia were associated with increased levels of suicide ideation, while increased depressive symptoms in patients with specific phobia and generalized anxiety disorder were associated with significantly lower levels of suicide ideation. The findings suggest that depressive disorders, but not anxiety disorders, constitute risk for suicide. Moreover, the differentiation between a depressive and an anxiety disorder as the principal diagnosis, as well as the assessment of anxiety-level symptoms in patients with major depressive episode and dysthymia, seems of special relevance when assessing suicide risk.
