Promoting gun trigger-lock use: insights and implications from a radio-based health communication intervention

A radio public service announcement (PSA) focusing on the danger to children from an unlocked and loaded gun was designed and aired 340 times on three radio stations in one Michigan county. At the end of the message, individuals were given a toll-free number to call to receive a free gun trigger-lock. Three surveys were used to assess the effectiveness of this intervention: a general population telephone survey, an automated telephone survey, and a follow-up mail survey. Approximately 20 percent of individuals in the general population heard the PSA. There was a significant increase in uncued knowledge of the locking-related gun-safety practices in the treatment county between time one and time two. Further, individuals in both counties had very high levels of self-efficacy and response efficacy, moderate levels of perceived severity, and very low levels of perceived susceptibility at both points in time. Seven-hundred and ninety-nine individuals called the toll-free number to receive a free gun trigger-lock; or approximately 17 percent of gun-owning households exposed to the message. The majority of callers were males who owned guns primarily for hunting purposes and who planned to use the lock themselves. Follow-up survey results indicated that individuals were using the gun trigger-locks, and that they believed using gun trigger-locks was an easy and effective way to prevent gun injuries. Insights and practical implications of these findings are discussed.

沈约骈文论略

齐武帝永明年间,沈约等人提出声律论,不仅对诗歌创作造成影响,这一影响还延展到骈赋、骈文的创作中。它在一定程度上推动骈文形式要素走向定型。从创作技巧上来看,永明以后的骈文对形式特征的追求更加严格:对偶更工整精致,用典更繁密贴切,词藻更华美,声律更讲究。除《奏弹王源》外,沈约的大多数骈文都比较重视声韵之美,因此可以说,骈文发展到沈约,基本达到了成熟时期。
