Although past research has developed scales for the incidence, prevalence, and fear of student-on-student victimization (SSV),
little is known about the scaling of perceived risk (i.e., the cognitive appraisal of the chances of experiencing SSV). Hence,
this study examined self-report survey data for the perceived risk of SSV as measured in the Adolescent Index for School Safety
(AISS). Children in grades 7 through 10 (n=337) in a single Florida public school completed the AISS. Factor analyses using
Maximum Likelihood Estimation with Oblimin Rotation identified nine unique factors for perceived risk. Reliability analyses
found standardized Cronbach Alphas that ranged from .64 to .91, and seven out of the nine identified scales were above .80,
which suggested good to excellent internal consistency. Future research should examine the content validity, construct validity,
and predictive validity for the AISS and other self-report surveys of SSV dynamics.

This study investigated the influence of an authority figure on eyewitness identification. Participants watched a staged crime
and then were administered a photo lineup by either an authority (policeman) or non-authority figure (civilian). Participants
in the authority condition were more likely to choose a lineup member than those in the non-authority condition. There was
no effect of authority, however, on the accuracy of the identification decisions. The lack of a deleterious effect suggests
that the presence of a police officer during identification procedures does not create an unduly suggestive situation or have
undesirable effects on eyewitness identification decisions. Although witnesses' choosing behaviors did not increase the rate
of identification errors, the effect of the administrator's authority on choosing was reduced when unbiased instructions (vs.
biased instructions) were presented to the witnesses. Thus, support was found for the use of neutral instructions during eyewitness
identification procedures. 相似文献

The Federalist claims to present a republican response to thetypical political problems faced by republics. That solutionrequired a departure from all models of republics known at thattime, and in particular a break with Anti-Federalist modelsthat posited heavy reliance on responsibility, understood aseither political accountability or as moral and political virtue.The Federalist challenges the Anti-Federalist notion that a"no-gap polity" is the means to safe and effective republicanism.It also challenges those who believe that virtue of people orrulers is the precondition of a republican polity. Publius doesrequire quasi-virlues of certain sortsand thus does notrely entirely on calculating selfinterestbut these aresignificantly different from the virtues posited by earlierrepublican theorists or certain contemporary interpreters ofThe Federalist. 相似文献
