Ourtown for teens: Long-term impact of a youth diversity program

This study fills a gap in the literature in regards to the effectiveness of youth diversity programs by exploring the sustaining effects of a week-long youth diversity camp program. Using both qualitative and quantitative methods, the study results suggest the camp achieved positive, sustaining impacts. Some of these findings include (1) enhancement of leadership skills; (2) greater understanding of “the other”; and (3) increased communication skills, particularly when oppression was observed. These effects were observed in the respondents who had recently attended the camp, as well as those who had attended a long time prior. Such impact reported in the study reiterates that more diversity programs for youth should be developed, implemented, and evaluated.     

Conflict Resolution in Mexican American Adolescents’ Friendships: Links with Culture,Gender and Friendship Quality

This study was designed to describe the conflict resolution practices used in Mexican American adolescents’ friendships, to explore the role of cultural orientations and values and gender-typed personality qualities in conflict resolution use, and to assess the connections between conflict resolution and friendship quality. Participants were 246 Mexican American adolescents (M = 12.77 years of age) and their older siblings (M = 15.70 years of age). Results indicated that adolescents used solution-oriented strategies most frequently, followed by nonconfrontation and control strategies. Girls were more likely than boys to use solution-oriented strategies and less likely to use control strategies. Familistic values and gender-typed personality qualities were associated with solution-oriented conflict resolution strategies. Finally, conflict resolution strategies were related to overall friendship quality: solution-oriented strategies were positively linked to intimacy and negatively associated with friendship negativity, whereas nonconfrontation and control strategies were associated with greater relationship negativity.

Evaluation of Four Fingerprint Development Methods for Touch Chemistry Using Matrix‐Assisted Laser Desorption Ionization/Time‐of‐Flight Mass Spectrometry,

Four preparation techniques for MALDI/TOF mass spectrometry were compared to determine the ability to gather intelligence for investigations through the chemical analysis of latent fingerprints, defined as “touch chemistry.” Compatible fingerprint development processes used for identification along with new techniques are necessary to evaluate touch chemistry. Ten volunteers deposited fingerprints from solvent residues containing drugs and explosives onto microscope slides. The developers included (A) fingerprint powder, (B) MALDI matrix, (C) fingerprint powder and lifting, and (D) cyanoacrylate fuming with fingerprint powder. Qualitative identification was based on ion images and spectra. The highest average detection rates (88%) were found using methods A and B. Methods C (52%) or D (18%) had limited success. Results demonstrate the importance of imaging coupled to extracted mass spectral data in detecting analytes in deposited fingerprints. Overall, the results suggest continued development of touch chemistry applications could prove useful for gathering intelligence and forensically relevant information.     

JUST: a measure of jury system trustworthiness

ABSTRACT

Three studies developed and tested a new measure of the perceived trustworthiness of the jury system, the 23-item Jury System Trustworthiness (JUST) scale, and assessed the scale’s convergent and discriminant validity. Study 1 assessed the scale’s factor structure and relation to other relevant constructs. In Studies 2 and 3, the JUST scale was administered to participants in two separate mock juror studies. The results of all three studies supported the hypothesized factor structure of the measure but showed that a simplified, 7-item measure was also effective. Overall, participants’ perceptions of juries were moderately positive, and the JUST scale was related to attitudes toward the police, authoritarianism, belief in a just world, juror bias, preference for a jury (vs. a bench) trial, and intention to respond to a jury summons. It also explained a unique portion of the variance in jury-specific beliefs and behavioral intentions, such as preference for a jury trial and response to a summons, beyond that accounted for by other legal attitudes. The JUST scale was not related to verdict decisions in either mock trial after controlling for authoritarianism. Several individual differences (e.g. age, race/ethnicity) were also related to attitudes toward the jury system.     

Knowing and Intelligent: A Study of Miranda Warnings in Mentally Disordered Defendants

A conservative estimate is that 695,000 mentally disordered offenders are arrested and Mirandized annually in the United States. Past research has focused almost exclusively on cognitive factors affecting the comprehension of Miranda rights. The current study broadens the scope by including diagnostic variables and by extending the investigation to basic elements of Miranda reasoning. A sample of 107 mentally disordered defendants was administered two research measures, the Miranda Statements Scale (MSS) and Miranda Rights Scale (MRS), in addition to standardized tests. Most defendants lacked good comprehension of all but the simplest (Flesch-Kincaid<6th grade) Miranda warnings. Defendants with the poorest understanding (i.e., comprehending about 25% of the warnings) had marked deficits in multiple domains including cognitive abilities (intelligence and comprehension) and general adjustment. Different background and clinical variables predicted defendants' abilities to generate reasons either to exercise or waive their Miranda rights.     

Mothers’ Motivations for Intimate Partner Violence Help-Seeking

The purpose of this study was to determine motivators for intimate partner violence (IPV) help-seeking among mothers. This qualitative study used English and Spanish-speaking focus groups and a grounded theory approach. Sixty-two mothers participated in eight groups. Motivators for IPV help-seeking fell into two broad categories, internal and external motivators. Although participants cited numerous motivators for IPV help-seeking, recognizing the negative effects of IPV on their children, labeling the partner’s behavior as abusive and the intervention of others were particularly important. For many participants, the effects of IPV on their children were the most important motivator. Few women made the decision to seek help without the encouragement of others. Unique to the Spanish-speaking participants was the influence of immigration status and limitations to disclosure created by using significant others as translators. Exploration of incorporating these motivators into IPV intervention efforts is warranted.     

Assessing Danger: What Judges Need To Know

Every day, judges are faced with decisions regarding intimate partner violence (IPV) victims' requests for protection orders, custody arrangements, and visitation schedules. To make informed decisions, judges must understand victims' risk for future violence. This mixed method study explores the extent to which protection order petitions (n=169) communicate victims' current danger and future risk of violence. Methods included interviews coupled with an archival review of court petitions. Findings suggest judges are inadequately prepared to render decisions to improve victim safety in the absence of standardized risk assessments. The Danger Assessment provides an evidence-based solution to routinize intake interviews with victims petitioning the court.     

Assessing a novel room temperature DNA storage medium for forensic biological samples

The ability to properly collect, analyze and preserve biological stains is important to preserving the integrity of forensic evidence. Stabilization of intact biological evidence in cells and the DNA extracts from them is particularly important since testing is generally not performed immediately following collection. Furthermore, retesting of stored DNA samples may be needed in casework for replicate testing, confirmation of results, and to accommodate future testing with new technologies.A novel room temperature DNA storage medium, SampleMatrix™ (SM; Biomatrica, Inc., San Diego, CA), was evaluated for stabilizing and protecting samples. Human genomic DNA samples at varying amounts (0.0625-200 ng) were stored dry in SM for 1 day to 1 year under varying conditions that included a typical ambient laboratory environment and also through successive freeze-thaw cycles (3 cycles). In addition, spiking of 1-4× SM into samples prior to analysis was performed to determine any inhibitory effects of SM. Quantification of recovered DNA following storage was determined by quantitative PCR or by agarose gel electrophoresis, and evaluation of quantitative peak height results from multiplex short tandem repeat (STR) analyses were performed to assess the efficacy of SM for preserving DNA.Results indicate no substantial differences between the quality of samples stored frozen in liquid and those samples maintained dry at ambient temperatures protected in SM. For long-term storage and the storage of low concentration samples, SM provided a significant advantage over freezer storage through higher DNA recovery. No detectable inhibition of amplification was observed at the recommended SM concentration and complete profiles were obtained from genomic DNA samples even in the presence of higher than recommended concentrations of the SM storage medium. The ability to stabilize and protect DNA from degradation at ambient temperatures for extended time periods could have tremendous impact in simplifying and improving sample storage conditions and requirements. The current work focuses on forensics analysis; however this technology is applicable to all endeavors requiring storage of DNA.
