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

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

This article presents findings from a quasi-experimental study of the St. Louis County (Duluth, Minnesota) ICWA Court examining its effectiveness at achieving improved ICWA implementation and a better case process and outcomes for Indian families. Using a case file review method, cases prior to implementing the ICWA Court were compared to post-ICWA Court cases on demographics, case characteristics, application of ICWA requirements, presence of parties at hearings, achievement of child permanency outcomes, and permanency timeliness. Compared to pre-ICWA Court, this study found several statistically significant improvements in the ICWA Court's handling of cases, including taking less time to confirm the case as an ICWA case, greater appearance of tribal representatives by the Dispositional review hearing stage, more active efforts findings, more placements with relatives at earlier stages of the case, more placement with relative outcomes when reunifications were not possible, and timelier permanency. 相似文献

Assessing the impact of stricter alcohol advertising standards: the case of Beam Global Spirits 下载免费PDF全文

Reducing youth exposure to alcohol advertising is a global health priority. In most countries around the world, the alcohol industry is given the opportunity to regulate itself with respect to advertising practices. Generally, the alcohol industry self‐regulations are lax, allowing youth to be disproportionately exposed to alcohol advertising. However, Beam Global Spirits and Wine (Beam) voluntarily adopted more restrictive advertising standards in the United States in 2007. This study assessed Beam's compliance with their new standard and estimates its effect on youth exposure and advertising costs. We found that Beam's compliance with its more restrictive standards was imperfect, but never‐the‐less, we estimated that youth exposure to alcohol advertising was reduced compared to other spirits brands. Beam's more restrictive standards did not increase their advertising costs, and therefore other alcohol companies should consider adopting similar standards around the world.
