In this paper, the marks on the concave keys used as guide keys duplicated by machine which has the function of profile modeling was analyzed systematically by experiments. In the experiment, the research concentrated on following aspect, the distinguish between mark on the concave key duplicated by machine with the producing mark and the using mark, the regularities of distribution and emergence probability of the characteristic marks on the key duplicated. The experimental research indicates that there are distinctive marks on the keys when normally used and when used as guide keys. The marks formed on the region that profile modeling needle touches in the process of duplicating have distinguishing characteristic. Therefore, the method is put forward that the examination of concave key can reveal distinctive marks whether the key has been used as a guide to create another key, it will be very useful to estimate criminality and analyze criminal scene.

Primary Reduction

This paper reviews the evidence for a secondary transfer effect of intergroup contact. Following a contact’s typical primary reduction in prejudice toward the outgroup involved in the contact, this effect involves a further, secondary reduction in prejudice toward noninvolved outgroups. Employing longitudinal German probability samples, we found that significant secondary transfer effects of intergroup contact exist, but they were limited to specific outgroups that are similar to the contacted outgroup in perceived stereotypes, status or stigma. Since the contact-prejudice link is bidirectional, the effect is inflated when prior prejudice reducing contact is not controlled. The strongest evidence derives from experimental research. Both cognitive (dissonance) and affective (evaluative conditioning) explanations for the effect are offered.

External Measure

Very old studies and clinical experiences of physicians already signal the ability of some patients to feel subclinical signs. These patients are called sentinel patients because they can anticipate crisis very early and therefore intervene quickly to prevent them. Studies have shown that these patients develop these skills from their own experience, in steps which are similar to quasi-experimental research. They test and adjust their competence all the more easily as they have an objective external measure available. This faculty of patients suggests the possibility of using medical devices as a means of learning for patients to tutor themselves in support of this singular skill.
