Trace detection of meglumine and diatrizoate from Bacillus spore samples using liquid chromatography/mass spectrometry

Following the September 11, 2001 terrorist attacks, letters containing Bacillus anthracis were distributed through the United States postal system killing five people. A complex forensic investigation commenced to identify the perpetrator of these mailings. A novel liquid chromatography/mass spectrometry protocol for the qualitative detection of trace levels of meglumine and diatrizoate in dried spore preparations of B. anthracis was developed. Meglumine and diatrizoate are components of radiographic imaging products that have been used to purify bacterial spores. Two separate chromatographic assays using multiple mass spectrometric analyses were developed for the detection of meglumine and diatrizoate. The assays achieved limits of detection for meglumine and diatrizoate of 1.00 and 10.0 ng/mL, respectively. Bacillus cereus T strain spores were effectively used as a surrogate for B. anthracis spores during method development and validation. This protocol was successfully applied to limited evidentiary B. anthracis spore material, providing probative information to the investigators.     

Exploration of the Cyberbullying Victim/Offender Overlap by Sex

As usage of the Internet has grown to approximately 657 million users worldwide, criminality online has become more prevalent. Termed “cybercrime,” this form of criminal behavior can occur in several different. While cybercrime in general is fairly new comparably to crimes in the physical realm, one of the most recently recognized forms of cybercrime is cyberbullying. The present study will examine the victimoffender relationship. Results indicate that both males and females with lower levels of self-control were more likely to participate in cyberbullying by posting hurtful messages or pictures to Facebook. Second, both sexes were more likely to cyerbullying via Facebook if they had been cyberbullied as well.     

Frequency of Parental Violence Against Children in Chinese Families: Impact of Age and Gender

The present study examines the impact of child and parent gender on parental violence across age span of children and their parents in Hong Kong Chinese families. A randomly selected community sample of 1,019 households was surveyed. Results indicate that, in general, boys experience more frequent parental violence than girls and mothers engage in more violent behaviors against their children than fathers. Parental violence shows a curvilinear pattern with age of children, peaking at age 8 for boys and age 3 for girls. There is a pattern of declining frequency of parental violence as parental age increases across child gender. Fathers exhibit an inverted U pattern of violent behavior against their children, with a peak around age 31–40, while mothers have a steadily declining trend until age 46. Separate parental violence indices are constructed for boys and girls.     

Presidentas Rise: Consequences for Women in Cabinets?

Since 1999, women have democratically won the presidency eight times in Latin America and have named hundreds of ministers. This study argues that under certain conditions, presidentas are more likely than male presidents to improve women's cabinet representation. Two mechanisms, presidenta mandates and gendered networks, appear to drive the relationship. Furthermore, because the pool of ministerial candidates is shallower for women than for men, presidentas are most likely to advance women's representation in cabinets at the beginning of their term and for “feminine” ministries. A case study of Michelle Bachelet's 2006 ministerial appointments reveals initial evidence for the argument. Empirical implications are then tested with an original dataset of 1,908 ministers of all democratically elected Latin American presidents since 1999. Model results are consistent with the theory that presidentas are most likely to “make a difference” when they are least constrained by the supply of female ministerial candidates.     

From Maltreatment to Delinquency: Service Trajectories After a First Intervention of Child Protection Services

The relationship between maltreatment in childhood and delinquency in adolescence is recognized. However, the data available do not reveal what proportion of children under the supervision of child protection services (CPS) later transfer to youth legal services, nor the sequence of services provided by these two systems. This study sketches a preliminary portrait of Youth Criminal Justice Act (YCJA) incidence among Quebec children and adolescents as a consequence of a first crime after initial CPS case closure (N = 14,252). It quantifies the scope of the phenomenon and identifies the best predictors of YCJA incidence from among the administrative data available. Survival analysis revealed a 15.4% YCJA incidence for the entire cohort in the five and a half years following termination of initial intervention; boys between 12 and 17 years old when their initial CPS cases were closed were at the greatest risk (27.2%).     

Accommodating death penalty legislation: Personal and professional views of assistant district attorneys toward capital punishment

Reinstatement of the death penalty in New York in 1995 forced an entire generation of prosecutors to confront capital punishment for the first time in their professional capacities. A total of 191 assistant district attorneys (ADAs) from 44 of New York’s 62 county prosecutors’ offices responded to a written survey. The results show ADAs hold widely divergent views about capital punishments, although most respondents fail to recognize their colleagues maintain differing viewpoints. The return of the death penalty appears to have both personal and professional implications for New York ADAs, and has precipitated potentially significant changes in their work environments.
