Personality features of an adolescent female offending population

The incidence of adolescent offending has been shown to be different for young males and females. However, there is a lack of literature concerning adolescent female offenders, and despite research suggesting that personality factors may be linked with antisocial and criminal behaviour in adolescents and young adults; there have been a lack of studies investigating intra-sex personality differences in young female populations. The Millon Adolescent Clinical Inventory, a 160-item self-report personality measure, was administered to 26 non-offending and 28 offending adolescent females. It was found that the offending group was significantly less submissive, less conforming, more forceful, more oppositional and more likely to exhibit borderline personality traits than the control group. The offending group also had higher reported incidences of childhood abuse and family conflict, and were more prone to substance abuse, impulsive actions and suicide ideation. These initial findings suggest that personality differences may well exist between offending and non-offending adolescent females.     

The Battle for Baghdad: Testing Hypotheses About Insurgency From Risk Heterogeneity,Repeat Victimization,and Denial Policing Approaches

The Iraqi Insurgency (2003–2011) has commonly been characterized as demonstrating the tendency for violence to cluster and diffuse at the local level. Recent research has demonstrated that insurgent attacks in Iraq cluster in time and space in a manner similar to that observed for the spread of a disease. The current study employs a variety of approaches common to the scientific study of criminal activities to advance our understanding of the correlates of observed patterns of the incidence and contagion of insurgent attacks. We hypothesize that the precise patterns will vary from one place to another, but that more attacks will occur in areas that are heavily populated, where coalition forces are active, and along road networks. To test these hypotheses, we use a fishnet to build a geographical model of Baghdad that disaggregates the city into more than 3000 grid cell locations. A number of logistic regression models with spatial and temporal lags are employed to explore patterns of local escalation and diffusion. These models demonstrate the validity of arguments under each of three models but suggest, overall, that risk heterogeneity arguments provide the most compelling and consistent account of the location of insurgency. In particular, the results demonstrate that violence is most likely at locations with greater population levels, higher density of roads, and military garrisons.     

Ultrafast STR Separations on Short‐Channel Microfluidic Systems for Forensic Screening and Genotyping

There are situations in which it is important to quickly and positively identify an individual. Examples include suspects detained in the neighborhood of a bombing or terrorist incident, individuals detained attempting to enter or leave the country, and victims of mass disasters. Systems utilized for these purposes must be fast, portable, and easy to maintain. DNA typing methods provide the best biometric information yielding identity, kinship, and geographical origin, but they are not portable and rapid. This study details the development of a portable short‐channel microfluidic device based on a modified Agilent 2100 bioanalyzer for applications in forensic genomics. The system utilizes a denaturing polymer matrix with dual‐channel laser‐induced fluorescence and is capable of producing a genotype in 80 sec. The device was tested for precision and resolution using an allelic ladder created from 6 short tandem repeat (STR) loci and a sex marker (amelogenin). The results demonstrated a precision of 0.09–0.21 bp over the entire size range and resolution values from 2.5 to 4.1 bp. Overall, the results demonstrate the chip provides a portable, rapid, and precise method for screening amplified short tandem repeats and human identification screening.     

Youthful animal abuse and later problem behavior outcomes: findings from two generations

The objective of this study was to document the long-term relationship between youthful animal abuse and a variety of problem behavior outcomes later in life. Data were used from a national, longitudinal, and multigenerational sample collected by the National Youth Survey Family Study, which assessed families across 27 years from 1977 to 2004. The analytic sample consisted of 2538 individuals who were analyzed using multivariate ordinary least squares and logistic regression modeling that controlled for important demographic factors. Hypotheses were tested across two generations separately showing that a history of animal abuse does, indeed, predict later problem behaviors, including serious offending, marijuana use, other drug use, alcohol use, and deviant beliefs. Depending on the outcome examined, each model accounts for 5–34% of the variation in respondents’ problem behaviors. Within each model, animal abuse was often one of the strongest predictors. Implications of these findings, the study’s limitations, and future research directions are discussed.     

Diversion in youth justice: a pilot study of effects on self-reported mental health problems

As part of a larger study to evaluate the effects of a Liaison and Diversion scheme in community youth justice services, staff of newly established Youth Justice Liaison and Diversion (YJLD) teams undertook observational ratings and administered self-report mental health and risk measures to young people referred to this pathway. The overall objectives of the YJLD project were to divert young people from the criminal justice system and to coordinate other services in order to reduce their likelihood of reoffending and the extent of their mental health problems. Data were collected from five local authority areas in different parts of England. Young people thereby referred had an average of 5.4 h of contact with youth justice staff. For a sample of young people on whom data were available at the beginning and end of that process, there was evidence of a significant reduction in problems and a small but significant correlation between the amount of individual contact time with YJLD staff and the extent of change observed. Absence of a comparison sample limits the drawing of firm conclusions; however, recommendations are made for future controlled experimental studies.     

ARREST TRAJECTORIES ACROSS A 17‐YEAR SPAN FOR YOUNG MEN: RELATION TO DUAL TAXONOMIES AND SELF‐REPORTED OFFENSE TRAJECTORIES*

The purpose of this study was to evaluate the impact of different operationalizations of offending behavior on the identified trajectories of offending and to relate findings to hypothesized dual taxonomy models. Prior research with 203 young men from the Oregon Youth Study identified six offender pathways, based on self‐report data (Wiesner and Capaldi, 2003). The current study used official records data (number of arrests) for the same sample. Semiparametric groupbased modeling indicated three distinctive arrest trajectories: high‐level chronics, low‐level chronics, and rare offenders. Both chronic arrest trajectory groups were characterized by relatively equal rates of early onset offenders, which indicates, therefore, some divergence from hypothesized dual taxonomies. Overall, this study demonstrated limited convergence of trajectory findings across official records versus selfreport measures of offending behavior.     

Analysis of mutations in father–son pairs with 17 Y-STR loci

We have examined 389 father/son sample pairs from U.S. Caucasians, African Americans, Hispanics and Asians using the 17 Y-STR loci in the Yfiler™ kit and observed a total of 24 differences between father and son. Thirteen mutations resulted in the gain of a repeat in the son and 11 resulted in a loss of a repeat. All samples resulted in single repeat mutations except one sample which contained a two repeat loss at Y-GATA-H4. Furthermore, two different sample pairs were found to have two mutations. An African American sample pair had a mutation at DYS458 and a second at DYS635 and an Asian sample pair had mutations at DYS439 and Y-GATA-H4.     

New alleles and mutational events at 14 STR loci from different German populations

The molecular origin of DNA mutations and the mutation rates were analyzed at 14 short tandem repeat (STR) loci with samples from trio cases derived from 10 different German population samples. STR loci comprised of D2S1360, D3S1744, D4S2366, D5S2500, D6S474, D7S1517, D8S1132, D10S2325, D12S391, D18S51, D19S246, D20S480, D21S226, and D22S689. In a total of 488 meioses, 16 isolated genetic inconsistencies in 8 different STRs were observed, whereas no mutations were found at the other loci. The data of five mutations suggested the presence of silent or null alleles due to sequence variation in primer binding site. This could be confirmed for four suspected cases by the use of alternative primer sets and by DNA sequence analyses. Furthermore, this study revealed nine new allelic variants at five different loci.     

Tat蛋白对马传染性贫血病毒长末端重复序列启动子活性的影响

将来源于马传染性贫血病毒(EIAV)强毒株第25代和第118代病毒的LTR,白细胞弱毒(EIAV-DLA)的LTR,以及TAR起始碱基和/或poly(A)附加位点发生突变的驴胎皮肤细胞弱毒(EIAV-FDD)的LTR分别克隆到pCAT3-Basic质粒中,获得了6个重组质粒pCAT-25、pCAT-118、pCAT-FD、pCAT-G219A、pCAT-A294C和pCAT-G219A-A294C。同时用pcDNA3.1(+)构建了EIAV反式激活蛋白(Tat)基因的重组真核表达质粒pcTM7-D。将pcTM7-D分别与含有不同LTR的重组质粒共转染驴胎皮肤细胞,考察Tat对LTR启动子活性的增强作用。结果表明,在皮肤细胞中Tat蛋白可以特异性增强来源于皮肤细胞弱毒疫苗株LTR的启动子活性,而对白细胞源的LTR无明显增强作用;TAR起始位点和poly(A)的单碱基突变和联合突变对Tat的反式激活作用并无明显影响。
