A Comparison of Enhancement Techniques for Footwear Impressions on Dark and Patterned Fabrics,

The use of chemical enhancement techniques on porous substrates, such as fabrics, poses several challenges predominantly due to the occurrence of background staining and diffusion as well as visualization difficulties. A range of readily available chemical and lighting techniques were utilized to enhance footwear impressions made in blood, soil, and urine on dark and patterned fabrics. Footwear impressions were all prepared at a set force using a specifically built footwear rig. In most cases, results demonstrated that fluorescent chemical techniques were required for visualization as nonfluorescent techniques provided little or no contrast with the background. Occasionally, this contrast was improved by oblique lighting. Successful results were obtained for the enhancement of footwear impressions in blood; however, the enhancement of footwear impressions in urine and soil on dark and patterned fabrics was much more limited. The results demonstrate that visualization and fluorescent enhancement on porous substrates such as fabrics is possible.     

The influence of neuropsychological deficits in early childhood on low self-control and misconduct through early adolescence

Purpose

Gottfredson and Hirschi (1990) contend that low self-control is the result of parental management techniques. However, an emerging line of research has revealed that neuropsychological deficits influence the development of low self-control ( and ). Nevertheless, these studies have largely tested the effects of neuropsychological deficits on low self-control cross-sectionally or in the short term. This study addresses an important void in the literature by examining the influence of neuropsychological deficits in early childhood on levels of self-control and misconduct through early adolescence.

Methods

Data come from the Early Childhood Longitudinal Survey, Kindergarten (ECLS-K), the largest nationally representative sample of U.S. children.

Results

We found that deficits in neuropsychological functioning during kindergarten were consistently predictive of lower levels of self-control during the third, fifth, and eighth grade as well as higher levels of conduct problems during the eighth grade. These effects remained significant after accounting for demographic variables, features of the neighborhood, and a number of parenting variables.

Conclusions

Neuropsychological deficits during early childhood play an important role in the development of low self-control through early adolescence and misconduct during early adolescence.     

Implementing Open Innovation in the Public Sector: The Case of Challenge.gov

As part of the Open Government Initiative, the Barack Obama administration has called for new forms of collaboration with stakeholders to increase the innovativeness of public service delivery. Federal managers are employing a new policy instrument called Challenge.gov to implement open innovation concepts invented in the private sector to crowdsource solutions from previously untapped problem solvers and to leverage collective intelligence to tackle complex social and technical public management problems. The authors highlight the work conducted by the Office of Citizen Services and Innovative Technologies at the General Services Administration, the administrator of the Challenge.gov platform. Specifically, this Administrative Profile features the work of Tammi Marcoullier, program manager for Challenge.gov , and Karen Trebon, deputy program manager, and their role as change agents who mediate collaborative practices between policy makers and public agencies as they navigate the political and legal environments of their local agencies. The profile provides insights into the implementation process of crowdsourcing solutions for public management problems, as well as lessons learned for designing open innovation processes in the public sector.
