Perceptions of control,depressive symptomatology,and self-esteem of women in transition from abusive relationships

The relation between women’s histories of experiencing violence and current psychological health were examined. Locus of control, feelings of personal power, depressive symptomatology, self-esteem, and judgments of control over a contingently responsive computer display were investigated in groups of 21 abused women and 18 comparison women. Within the sample of abused women, relationships between severity of abuse and the psychological variables were also examined. The group of abused women had lower beliefs in self-efficacy, were more depressed, and had lower self-esteem than the comparison women. There were no differences found, however, between the two groups in perceptions of control on the computer task. Severity of physical abuse among the abused women was positively correlated with depression scores. Verbal abuse was found to contribute significantly to many of the between-group differences. Empirical evidence of the positive impact of transition house residence on the abused women’s mental health was also presented. The importance of future research into both the differential effects of verbal and physical abuse on women and the role of the transition house in empowering abused women were discussed.     

The enhancement of intimacy and the reduction of loneliness among child molesters

The present report describes the component of our treatment program that is aimed at enhancing intimacy skills and reducing loneliness in sexual offenders. The evaluation of this component, although limited in sophistication, offers data that encourages confidence in the value of the treatment component.     

Development of a finger printing device for use on a mobile robot

In this paper, we describe the development of a device for fuming fingerprints with cyanoacrylate (Super Glue) to enable police tactical units to obtain fingerprint evidence from suspicious packages using a remote-controlled robot. Through a series of initial experiments and preliminary designs, we show that effective cyanoacylate fuming requires sufficient heat, humidity, and airflow. This work led to the development of a final working prototype, called robot accessory for fuming fingerprint evidence (RAFFE), which is currently being field tested by the Calgary Police Service.     

Y-SNP typing of U.S. African American and Caucasian samples using allele-specific hybridization and primer extension

Multiplex analysis of genetic markers has become increasingly important in a number of fields, including DNA diagnostics and human identity testing. Two methods for examination of single nucleotide polymorphisms (SNPs) with a potential for a high degree of multiplex analysis of markers are primer extension with fluorescence detection, and allele-specific hybridization using flow cytometry. In this paper, we examined 50 different SNPs on the Y-chromosome using three primer extension multiplexes and five hybridization multiplex assays. For certain loci, the allele-specific hybridization method exhibited sizable background signal from the absent alternate allele. However, 100% concordance (>2000 alleles) was observed in ten markers that were typed using both methods. A total of 18 unique haplogroups out of a possible 45 were observed in a group of 229 U.S. African American and Caucasian males with the majority of samples being assigned into 2 of the 18 haplogroups.     

Trace analysis of peroxide explosives by high performance liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry (HPLC-APCI-MS/MS) for forensic applications

An HPLC-APCI-MS(/MS) method for the (trace) analysis of the most commonly encountered peroxide explosives, hexamethylenetriperoxidediamine (HMTD) and triacetonetriperoxide (TATP), has been developed. With this method, HMTD and TATP have been analyzed in the same run. (Pseudo-)molecular ions of these peroxides have been obtained as base peak under the same condition. A series of product ions was produced from these pseudo-molecular ions ([HMTD - 1]+ and [TATP + NH4]+) in the MS/MS analysis. We also pioneered in showing that a TATP molecular ion [TATP + H]+ can be observed with HPLC-MS/MS. The limit of detection for HMTD and TATP was 0.26 and 3.3 ng, respectively, on column by HPLC-MS in the Full Scan mode and 0.08 and 0.8, respectively, by HPLC-APCI-MS/MS in Selected Reaction Monitoring (single mass unit) mode. The method presented has been applied successfully for the identification of peroxides in the bulk solid state (powder sample), as well as in post-blast extracts originating from a forensic case. For the post-blast extracts, the use of tandem MS has been shown clearly to be of crucial importance for the identification and detection of the peroxide explosives.     

Subway Train‐Related Fatalities in New York City: Accident versus Suicide*

Abstract: We examined the characteristics of subway train‐related fatalities in New York City between Jan. 1, 2003 and May 31, 2007 in order to determine which factors are useful in differentiating accident from suicide. Subway train‐related deaths with homicide and undetermined manners also are included. During this period, there were 211 subway train‐related fatalities. The manners of death were: suicide (n = 111), accident (n = 76), undetermined (n = 20), and homicide (n = 4). The causes of death were blunt trauma (n = 206) and electrocution (n = 5). Torso transection and extremity amputation were more frequent in suicides. Antidepressant medications were more frequently detected in suicides, whereas cocaine and ethanol were more frequent in accidents. However, autopsy findings should be weighed in the context of the entire evaluation along with other circumstantial and investigative findings. In unwitnessed deaths where additional information is unavailable or discrepant, the most appropriate manner of death usually is undetermined.
