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.     

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.     

Understanding third‐party advertising: An analysis of the 2004, 2006 and 2008 Canadian elections

For approximately two decades, the federal regulation for third‐party election spending was the focus of repeated constitutional debate. However, with the 2004 Supreme Court decision in Harper v. Canada, a relative level of policy stability has been established. This stability permits us to evaluate the performance of spending limits according to the principles of the egalitarian model on which it is based. Using an original data set compiled from third‐party election advertising reports from the 2004, 2006 and 2008 federal elections, this article offers the first empirical analysis of this important election policy. A number of observations can be offered. First, third parties are not spending large amounts relative to spending limits. Second, despite legislative changes in 2006 banning all federal party contributions except those from individuals, there appears little strategic action by third parties in spending “around” contribution limits. During this three‐election cycle, third parties quite simply did not spend significant amounts. Current third‐party spending limits therefore appear to be situated comfortably within the expectations of the egalitarian model, though why third parties of all types spend so little remains in question.     

Examining Factors Co-Existing with Interpersonal Violence in Lesbian Relationships

Interpersonal violence within lesbian relationships is a significant yet understudied problem. Women attending a gay pride festival in Atlanta, GA, were asked to complete a survey concerning same-sex interpersonal violence. Women who reported being in a current or previous same-sex partner relationship were included in the analyses (N = 226). Factors that occurred in the context of interpersonal violence were investigated: substance use, HIV/STI risk behaviors, barriers to reporting abuse, and attitudes inhibiting seeking of social support. In addition, the survey assessed relationship-related power dynamics. Results of multivariate analyses support the hypotheses that power imbalance and inequality when making sex-related decisions within women’s same-sex relationships are associated with interpersonal violence. Further findings suggested that a combination of factors must be considered when dealing with and reducing the risk for violence in same-sex relationships.
