Capillary electrophoretic analysis of phosphorus species in clandestine methamphetamine laboratory samples

The clandestine manufacture of methamphetamine is a spreading epidemic. Manufacturing methods are constantly changing, necessitating the implementation of new analytical tools to identify materials from these labs. Characterization of phosphate, phosphite, and hypophosphite ions is necessary to distinguish the various phosphorus-iodine manufacturing methods that are popular methods for reducing pseudoephedrine to methamphetamine. This work describes a capillary electrophoresis method to separate acetate, azide, bromide, carbonate, chlorate, chloride, chromate, fluoride, hypophosphite, iodide, nitrate, nitrite, perchlorate, phosphate, phosphite, sulfate, sulfite, and thiocyanate. The CElixerOA 8.2 dynamic coating system was modified by lowering the capillary temperature to 15 degrees C and using an acid flush between runs to remove adsorbed materials. This allows detection of ions down to between 10 and 30 parts per million with percent relative standard deviations of normalized migration times under 0.1%. This method is a valuable tool for the characterization of phosphate, phosphite, and hypophosphite in routine analysis of clandestine methamphetamine manufacturing evidence and has a broader application in other areas of forensic analysis.     

Composition of bacillus species in aerosols from 11 U.S. cities

A PCR-based heteroduplex assay was used to determine the presence and composition of Bacillus species in 11,059 Environmental Protection Agency PM2.5 aerosol samples from 11 U.S. cities. The assay differentiated three groups: Type A containing Bacillus anthracis and very closely related, often pathogenic, Bacillus cereus and Bacillus thuringiensis strains; Type B containing other B. cereus and B. thuringiensis strains; and a third group of more-distantly related Bacillus species. Eight of the 11 cities were positive for Bacillus species in 50% or more of the samples, and the percent of aerosol samples that contained the HD Type A group ranged from 3% to 32%. Cities from the eastern half of the United States generally contained a higher frequency and broader diversity of Bacillus species than the western half of the United States. Positive samples were detected throughout the year. These results have implications for pathogen detection in environmental samples, understanding the natural evolution of new pathogenic strains, and incidence of infection caused by strains of the B. cereus subgroup.     

The Nature and Predictors of Sexual Victimization and Offending Among Adolescents

This study describes the risk factors associated with experiencing and committing sexual aggression among a sample of male and female adolescents. High school students completed a questionnaire containing a revised form of the Sexual Experiences Survey to assess sexual victimization and offending experiences. Ordinal regression equations were estimated separately for male and female students, regressing background characteristics, dating behaviors, and attitudinal scales on sexual victimization (for females) or offending (for males). Nearly half (48%) of the females report experiencing sexual aggression, and one-third (34%) of males admit committing this type of offending. Regression analyses show that the likelihood of reporting victimization/offending increases among females who report dating more frequently during the past month, among both males and females who report dating more different people during the past 6 months, and among older males. Females who report their religious affiliation as Protestants compared to those with no religious affiliation, and those planning to attend college are less likely to report victimization. Among the males, rejecting rape stereotypes and having more accurate legal knowledge regarding rape are related to reduced likelihoods of reporting sexual offending. Implications for improving sexual assault educational programs for adolescents are discussed.     

Do Mothers and Teens Disagree About Sexual Communication? A Methodological Reappraisal

This study investigated whether parent–teen disagreement in reports of sexual discussions is due to methodological factors. Forty-four mothers and their 12- to 15-year-old daughters (n = 18) and sons (n = 26) completed parallel questionnaires including measures of communication about 18 different sexual topics during the teen's entire life and during the past year. Analyses examined whether congruence rates were influenced by the use of global as compared to specific items, assessment of conversations during the teen's entire life as compared to the past year, and use of forced-choice as opposed to continuous-response categories. Taken as a whole, results support the notion that methodological limitations are partly responsible for lack of congruence in parent–teen reports. Suggestions for methodological improvements in future research are discussed.     

The Resource Center for Separating and Divorcing Families: Interdisciplinary Perspectives on A Collaborative and Child‐Focused Approach to Alternative Dispute Resolution

The Resource Center for Separating and Divorcing Families (RCSDF) is a teaching model for providing interdisciplinary services to separating and divorcing families. The model was developed by the Honoring Families Initiative at the Institute for the Advancement of the American Legal System at the University of Denver. Services are provided by graduate and law students at the University of Denver, working side‐by‐side with a supervising licensed attorney, psychologist, and social worker. The experiential and interdisciplinary model of teaching and providing direct client services is the first of its kind in the United States. RCSDF students and staff seek to empower parents to make positive decisions about their family's future in a supportive and educational environment.

Key Points for the Family Court Community
• The current system of preparing graduate and law students for careers in family law is in need of improvement. This article provides information for educators and the family law community about the impact of interdisciplinary and experiential learning for students.
• Parents going through the transition of separation or divorce experience psychological and financial stressors that can create serious behavioral and adjustment issues for their children. The RCSDF works in a holistic manner with parents and children to minimize the levels of stress and anxiety during the transition.

     

The content of suicide notes from attempters and completers

A study of the content of suicide notes from attempted suicides and completed suicides was conducted using the Linguistic Inquiry and Word Count (LIWC) text analysis program. Notes from completed suicides had fewer metaphysical references, more future tense verbs, more social references (to others) and more positive emotions than did the notes from attempted suicides. The implications of these results were discussed.     

Stay With or Leave the Abuser? The Effects of Domestic Violence Victim’s Decision on Attributions Made by Young Adults

While negative attributions are often made toward female victims of domestic violence, studies have not explored whether attributions shift contingent upon whether women stay with or leave abusive husbands. Further, no studies investigated whether negative attributions decrease if the participants receive information about the prevalence of domestic violence or the risks inherent in leaving an abuser. Therefore, two studies were designed that investigated attributions made by young adults when women either stay with or leave an abusive husband and whether educating the participants about prevalence of domestic violence and risks of leaving mitigate negative judgments. In both studies, young adults responded to surveys assessing attributions toward a female heterosexual victim of domestic violence. Results indicated that participants made more positive attributions about her personality characteristics and parenting ability if a woman left the relationship. Informing students beforehand about potential risks of leaving and personal experience with domestic violence did not erase this effect, but interactions mitigated some of the effects. Results suggest that educating young adults about risks of violence while useful, is not sufficient to change blaming attitudes. Educators may instead need to challenge the attribution process. Further research involving attributions toward gay and lesbian victims of domestic violence is suggested.
