Scholars have spent a great deal of effort examining the effects of negative advertising on citizens’ perceptions of candidates. Much of this work has used experimental designs and has produced mixed findings supporting one of two competing theories. First, negative ads may harm candidates who sponsor them because citizens tend to dislike negativity. Second, negativity may drive down citizens’ support for the targeted candidate because the attacks give people reasons to reject the target. We argue that the mixed findings produced by prior research may be driven by a disregard for campaign dynamics. We present a critical test of these two theories using data drawn from 80 statewide elections—37 gubernatorial and 43 U.S. Senate contests—from three election years and public opinion polling collected during the last 12 weeks of each campaign. We find that a candidate’s support declines as her advertising strategy includes a higher proportion of negative ads relative to her opponent and that this process unfolds slowly over the course of the campaign. 相似文献

This study investigated the prevalence of loss due to death and its association with mental disorders in a random sample of 898 newly detained adolescents in Chicago, Illinois. Nearly 90% of youth experienced the loss of an important person; most had also experienced a “high‐risk” loss (e.g., loss due to violence, sudden loss). Minority youth were at particular risk. Youth with any loss or multiple losses were more likely to have mood disorders and ADHD/behavioral disorders, respectively, than youth who had no such losses. Interventions focusing on modifiable protective factors following loss may increase positive outcomes in this vulnerable population. 相似文献
