FaSTR DNA: A new expert system for forensic DNA analysis

The automation of DNA profile analysis of reference and crime samples continues to gain pace driven in part by a realisation by the criminal justice system of the positive impact DNA technology can have in aiding in the solution of crime and the apprehension of suspects. Expert systems to automate the profile analysis component of the process are beginning to be developed. In this paper, we report the validation of a new expert system FaSTR DNA, an expert system suitable for the analysis of DNA profiles from single source reference samples and from crime samples. We compare the performance of FaSTR DNA with that of other equivalent systems, GeneMapper™ ID v3.2 (Applied Biosystems, Foster City, CA) and FSS-i³ v4 (The Forensic Science Service^® DNA expert System Suite FSS-i³, Forensic Science Service, Birmingham, UK) with GeneScan^® Analysis v3.7/Genotyper^® v3.7 software (Applied Biosystems, Foster City, CA, USA) with manual review. We have shown that FaSTR DNA provides an alternative solution to automating DNA profile analysis and is appropriate for implementation into forensic laboratories. The FaSTR DNA system was demonstrated to be comparable in performance to that of GeneMapper™ ID v3.2 and superior to that of FSS-i³ v4 for the analysis of DNA profiles from crime samples.     

Prospects For Monitored Retrievable Storage Of High-Level Nuclear Waste

The Nuclear Waste Policy Act of 1982 authorized the U.S. Department of Energy (DOE) to evaluate monitored retrievable storage (MRS) as an option to manage spent fuel and high-level radioactive waste. In 1987, the DOE sought Congressional approval for construction of an MRS at a site identified in Tennessee, despite adamant opposition from the State. An amendment in late 1987 nullified DOE's proposal, and established the MRS Commission and the High-Level Nuclear Waste Negotiator, institutions created as a result of the DOE/Tennessee dispute. This article analyzes DOE's siting attempt in Tennessee, the actions of the Commission and Negotiator, and examines the prospects for implementation of nuclear waste policy.     

Modern Central Banking: Pressures for Change

The role of the central bank as an instrument of government economic supervision has entered a period of flux, owing to the combined forces of financial deregulation, technological advance, monetary innovation and banking globalisation. This paper discusses, with special reference to Australia, pressing areas for potential reform in the role of the central bank including greater independence, international coordination, splitting of core functions, and the creation of a 'super-regulator'.     

Gender Differences Among Adolescents in Family,and Peer Influences on Body Dissatisfaction,Weight Loss,and Binge Eating Behaviors

The present study examined perceived family and peer influences on body dissatisfaction, weight loss, and binge eating behaviors in adolescents. Three hundred and six girls aged 11 to 17 years (M = 13.66, SD = 1.12) and 297 boys aged 11 to 18 years (M = 13.89, SD = 1.13) completed a questionnaire that examined the direct influence and quality of family and peer relationships on body dissatisfaction and disordered eating. Direct influences of family and peers, rather than the quality of these relationships, predicted body dissatisfaction and disordered eating in adolescent boys and girls. Interesting differences were found between girls and boys in the nature of the influences and in the way they were expressed. In particular, parental and peer discussion and encouragement of weight loss predicted disordered eating behaviors in girls, while maternal and peer encouragement predicted binge eating and weight loss behaviors in boys. Fathers played a salient role in the expression of more severe forms of eating problems, while siblings played a small yet significant role in cognitive restraint among girls. The findings highlight gender differences in the importance of significant others in the expression of body dissatisfaction and disordered eating in adolescence.     

Parental Cultural Affiliation and Youth Mental Health Service Use

Studies indicate that African American, Asian/Pacific Islander, and Latino youth have higher rates of unmet mental health needs and lower rates of mental health service utilization compared to non-Hispanic White youth, suggesting that obstacles may exist in the help-seeking and service utilization pathway for minority youth. Parental cultural factors may significantly impact youth service use, and acculturation is one way to measure adherence to culture specific values, beliefs, attitudes, and behaviors. In this study, parental acculturation level, conceptualized as cultural affinity to 1) mainstream American culture and 2) an alternative culture, were examined as potential mediators of the relationship between race/ethnicity and youth service use. The current subsample (n=1364) was drawn from the Patterns of Care study, a larger study of at-risk youth who were active to at least one of five public sectors of care. Our subsample included all youth aged 6–17 who were African American, Asian/Pacific Islander, Latino, or Non-Hispanic Whites (66.6% male). The results indicate that parental acculturation level as measured by affinity to an Alternative Culture was a partial mediator in the relationship between race/ethnicity and mental health service use for Asian/Pacific Islander and Latino youth.

A Longitudinal Investigation of the Development of Weight and Muscle Concerns Among Preadolescent Boys

The study examined the impact of body mass index (BMI), negative affect, self-esteem, and sociocultural influences in the development of weight and muscle concerns among preadolescent boys. Body dissatisfaction, importance placed on weight and muscles, weight loss strategies, and strategies to increase muscles were evaluated. Participants were 237 boys aged between 8 and 11 years who were tested at three assessment periods 8 months apart. The main predictor of boys’ body change strategies was their perceived pressures to modify weight and muscles from parents, peers, and the media. The other main predictor of boys’ body change strategies and the sole predictor of body dissatisfaction was BMI. Self-esteem and negative affect were found to be weak and generally nonsignificant predictors of boys’ body image concerns and body change strategies. Additional studies that examine the risk and protective factors associated with boys’ weight and muscle concerns are needed to assist in the development of prevention programs for preadolescent boys.Lina Ricciardelli is an Associate Professor at Deakin University.

Attitude Responsiveness and Partisan Bias: Direct Experience with the Affordable Care Act

This study evaluates the competing influences of motivated reasoning and personal experience on policy preferences toward the Affordable Care Act. Using cross-sectional and panel survey data, the findings reveal that healthcare attitudes are responsive to information that individuals receive through personal experience. Individuals who experienced a positive change in their insurance situation are found to express more positive views toward the health reform law, while individuals who lost their insurance or experienced an otherwise negative personal impact on their insurance situations express more negative views. The results point to personal experience as a source of information that can influence individuals’ preferences. However, although attitudes are responsive to the quality of one’s personal interactions with the healthcare system, the results also suggest that partisan bias is still at work. Republicans are more likely to blame the health reform law for negative changes in their health insurance situations, while Democrats are more likely to credit the law for positive changes in their situations. These motivated attributions for their personal situations temper how responsive partisans’ attitudes are to information acquired through personal experience.
