DNA Profiles from Fingerprint Lifts—Enhancing the Evidential Value of Fingermarks Through Successful DNA Typing

This study evaluated the compatibility of the most common enhancement methods and lifting techniques with DNA profiling. Emphasis is placed on modern lifting techniques (i.e., gelatin lifters and Isomark?) and historical fingerprint lifts for which limited research has been previously conducted. A total of 180 fingerprints were deposited on a glass surface, enhanced, lifted, and processed for DNA typing. DNA could be extracted and profiled for all the powders and lifts tested and from both groomed fingerprints and natural prints with no significant difference in the percentage of profile recovered. DNA profiles could also be obtained from historical fingerprint lifts (79.2% of 72 lifts) with one or more alleles detected. These results demonstrate the compatibility between different powder/lift combinations and DNA profiling therefore augmenting the evidential value of fingerprints in forensic casework.     

Politicians,the Representativeness Heuristic and Decision-Making Biases

Political Behavior - Do politicians use the representativeness heuristic when making judgements, that is, when they appraise the likelihood or frequency of an outcome that is unknown or unknowable?...     

The Challenges of Contracting and Accountability Across the Federal System: From Ambulances to Space Shuttles

This article focuses on two questions related lo governmentcontracting and accountability. How are key components of contractingsimilar or different for city, state, and federal governmentsin the United States? To what extent do the three levels ofgovernment share the widely recognized challenges of contractdesign and contract management? To address these questions,we compared and contrasted six contracting cases, two each forlocal, state, and the federal governments. We found that forall governments in the U.S. federal system, the public managementfunctions of contracting are remarkably similar, and that contractmanagement and the achievement of accountability are "weak links"in the contracting process. Our findings do not support thehypothesis that contract management is more effective in localgovernment relative to state and federal governments.     

Signs and symptoms of post-traumatic stress disorder in children

Summary Post-traumatic Stress Disorder in children is a complex interaction of cognitive, affective, and physiological responses to an event that is outside the range of usual human experience and would be markedly distressing to almost anyone. Traumatic stress reactions in children are conscious and unconscious efforts to assimilate an overwhelming event and have been identified in the past as panic reaction, acute grief hysterical reaction, and physical shock. PTSD in children is complicated by multiple issues of developmental stages, family dynamics, physical maturity, genetic predisposition, and cognitive skills. Characteristic symptoms of PTSD which must persist for more than one month include re-experiencing (flashbacks, nightmares); avoidance; numbing of general responsiveness; and persistent autonomic arousal. Children exhibit characteristic PTSD symptoms, but research suggests four criteria specific to traumatized children independent of chronological age and the course of the disorder: 1) visualized and repeatedly perceived memories; 2) repetitive behaviors; 3) trauma-related fears; 4) altered attitudes about life and future orientation. These four criteria appear to remain clustered together in childhood trauma victims even when other diagnosis would appear more appropriate. PTSD in children encompasses a complex spectrum of diagnosis and remains technically intricate for the mental health professional.     

Ideology and campaign activity at three levels of government

This article examines the relationship between self-designated political ideology, opinions on twenty-one issues, and campaign activity at local, state, and national levels. The samples examined include delegates to the 1984 Party Conventions in eleven states. Generally, the findings indicate that ideology and issue position are most strongly associated with activity in national campaigns. Among Democrats liberalism is associated with national activity, whereas among Republicans those who are conservative are most active in national campaigns. Some important intraparty differences are found between local campaign activists and national activists. For example, among Democrats local campaign activists are much more conservative than national activists on several issues.
