Visualization of fingerprint deposits by digital color mapping of light reflected from the surface of heated brass, copper, aluminum, and tin has been investigated using Adobe® Photoshop®. Metals were heated to a range of temperatures (T) between 50°C and 500°C in 50°C intervals with enhancement being optimal when the metals are heated to 250°C, 350°C, 50°C, and 300°C, respectively, and the hue values adjusted to 247°, 245°, 5°, and 34°, respectively. Fingerprint visualization after color mapping was not degraded by subsequent washing of the metals and color mapping did not compromise the visibility of the fingerprint for all values of T. The optimum value of T for fingerprint visibility is significantly dependent of the standard reduction potential of the metal with Kendall's Tau (τ) = 0.953 (p < 0.001). For brass, this correlation is obtained when considering the standard reduction potential of zinc rather than copper. 相似文献

Incubators are heterogeneous but there is a lack of understanding of the variety of innovation involved. We use four archetypes of incubator discussed in the literature (basic research, university, economic development and private incubator) and analyze their generation of different types of innovation (product, technological process and organizational innovation) during a 4 years period (2005–2008). In a sample of 80 incubators, we find that incubatees in some types of incubators are more prone to generate product and technological process innovations than those hosted in other types. 相似文献

Abstract: Focus on results and accountability in public performance management is now firmly entrenched. Governments around the world, at all levels, have invested significant time and resources into measuring and reporting performance, with very mixed results. In 2000, Ontario became the first state or province in North America to mandate a municipal performance measurement program for all municipalities. One measure of the system's effectiveness is the documentation produced to show citizens how their government is doing – in this case, an annual performance report. Although the legislation is clear in terms of measurements and some reporting standards, there are clear differences in the overall quality of the annual reports produced by each of the 445 municipalities. This article will focus on the reports as the primary communication tool between the municipalities and citizens. The primary question that frames this research is the current quality of municipal performance reports in Ontario. 相似文献

Violence in schizophrenia patients may result from many factors besides the symptoms of schizophrenia. This study examined the relationship between childhood antisocial behavior and adult violence using data from the NIMH CATIE study. The prevalence of violence was higher among patients with a history of childhood conduct problems than among those without this history (28.2% vs. 14.6%; P < 0.001). In the conduct-problems group, violence was associated with current substance use at levels below diagnostic criteria. Positive psychotic symptoms were linked to violence only in the group without conduct problems. Findings suggest that violence among adults with schizophrenia may follow at least two distinct pathways-one associated with premorbid conditions, including antisocial conduct, and another associated with the acute psychopathology of schizophrenia. 相似文献

The case of a 48-year-old woman accused of killing at least 12 elderly women and attempting to kill another one during the last 3 years is presented. Extensive neuropsychological, electrophysiological, and neuropsychiatric testing showed no evidence of a DSM-IV-TR Axis I diagnosis, but a decrease in executive functions and abnormalities in the processing of affective stimuli were found. Behavioral and psychophysiological studies revealed dissociation between knowing how to behave and actually behaving in socially acceptable ways. According to the woman, killing was just her response to "humiliating situations." Two potentially significant conditions in her past history are found: (i) childhood abuse; and (ii) multiple head injuries. It is conjectured that the nature of her crimes, paranoid and personality traits, a probable frontal brain dysfunction, as well as a specific demographic and social context represent unusual factors accounting for her violent behavior. 相似文献
