Study of the diagnostic value of iron in fresh water drowning

The aim of our study was to test the diagnostic value of iron (Fe) in fresh water drowning by investigating the postmortem levels of hemodilution in drowning cases compared to control cases. Twenty-six typical fresh water drowning cases were selected from 128 immersion cases autopsied in our Department of Forensic Pathology between 1998 and 2004. The exclusion criteria were a long postmortem interval and other causes of death than drowning. For all selected cases, the diagnosis of drowning was based on the presence of autopsy findings and positive diatom test. A control population of 12 cases was also selected. For each drowning and control case, iron blood levels were measured in the left ventricle (LV) and right ventricle (RV) of the heart. The mean difference of iron concentration (RVFe-LVFe) between the drowning group and the control group was statistically compared. Furthermore, iron measurements were performed in 19 drowning cases showing advanced putrefaction. The mean difference of iron concentration was significantly higher in the drowning cases compared with controls (P<0.001). All drowning cases showed hemodilution. No overlap was found in the RVFe-LVFe levels between the two groups. Resuscitation attempts seemed to have no effect on the results. In cases of drowning showing advanced putrefaction, the iron test was not reliable because biochemical iron measurement was often prevented by no sufficient blood in the heart or postmortem clots. In conclusion, according to our results, iron seems to be a good biochemical marker in fresh water drowning with a short postmortem interval.     

STR data for nine Y-chromosomal loci in Guinea Equatorial (central Africa)

Allele and haplotype frequencies for nine Y-specific STR loci (DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS393, DYS434, DYS437, and DYS439) were obtained from a sample of 57 males from Guinea Equatorial.

Empirical evidence for AMBER alert as crime control theater: a comparison of student and community samples

While the AMBER Alert system is intended to facilitate the rescue of abducted children, it has practical and psychological limitations. Participants indicated their emotions and perceptions about Alerts before and after reading a vignette that manipulated details about a child abduction. Results indicate that the Alert system fits some criteria of Crime Control Theater (CCT). CCT polices are emotion-based legal actions that appear to address crime but fail to do so and have unintended consequences. Participants experienced panic about child abduction and believed the system is an effective tool which should be used no matter the unintended consequences. Emotions and panic positively related to perceptions of the system. Still, perceptions were not particularly positive, indicating that some participants recognize the system's limitations. Female and community participants generally had more positive perceptions than males and students, especially when experiencing high emotions or panic. Reading about an abduction reduced emotions overall and led to more positive perceptions (but only in the ‘AMBER Alert success’ condition). Reading about an ‘Alert failure’ did not affect perceptions. Results highlight the role of emotion in shaping perceptions of the system. As with other CCT policies, lawmakers should rely less on community sentiment and more on science when adopting legislation.     

Dispositional empathy in neglectful mothers and mothers at high risk for child physical abuse

This study investigates whether mothers who are neglectful and at high risk for child physical abuse present a deficit in empathy. Participants were neglectful mothers (n=37), mothers at high risk for child physical abuse (n=22), and nonmaltreating mothers (n=37). The Interpersonal Reactivity Index, a self-report measure assessing specific dimensions of empathy, was used to assess dispositional empathy. No differences between neglectful and non-neglectful mothers were found for perspective taking, empathic concern, and personal distress. High-risk mothers reported less perspective taking and more personal distress than nonmaltreating mothers. No difference between groups was found for empathic concern. The present study supported the hypothesis that parents at high risk for child physical abuse show a deficit in particular aspects of dispositional empathy: personal distress and perspective taking. However, no differences were found between neglectful and nonmaltreating mothers in any dimension of dispositional empathy.     

Building Secure and Transparent Elections through Standard Operating Procedures

Election reform has evolved since the 2000 presidential election. One issue that has remained at the forefront of public debate is how to build confidence in the election process. The foundation for confidence is based on procedures for electoral security and transparency. In this article, the authors use legal theories of evidence and public administration theories related to standard operating procedures to consider how election fraud—and claims of fraud—can be prevented by having effective and rigorous chain of custody procedures. Using case studies, they show how such chains of custody can be implemented and examine which states have processes and procedures that promote the transparency that is critical for public examination of the electoral process. They conclude with a consideration of best practices in this area.     

A new barrier to participation: Heterogeneous application of voter identification policies

In democratic societies there is a tension between maximizing ballot access and minimizing voter fraud. Since the 2000 presidential election, this tension has been central to discussions about election reform at the national, state, and local level. We examine this tension by focusing on the implementation of voter identification laws in one state that has experienced significant issues in recent elections, and that is currently implementing election reform: New Mexico. We hypothesize that Hispanic voters are more likely to show some form of identification than other types of voters. Using a voter data set from New Mexico's First Congressional District in the 2006 election, we find that Hispanic, male and Election Day voters are more likely to show some form of identification than non-Hispanic, female and early voters. In addition, using an overlapping study of Bernalillo County 2006 poll workers, which almost entirely overlaps with the First Congressional District, we find no evidence that differences in poll worker partisanship or ethnicity produce differences in voter identification procedures. Our findings suggest that broad voter identification laws, which may be applied unequally, may be perceived as discriminatory.
