Observations of high velocity bloodspatter on adjacent objects

In a recent homicide investigation, high velocity backspatter was observed on the sleeve cuff of the accused. These minute droplets were discovered only after microscopic examination and were limited in number. A study was initiated to determine if these were truly backspatter droplets or transferred blood produced from light contact with a bloody item. It was observed that the backspattered blood was primarily limited to contact or near contact shots. An exception was a shot into an already bloody surface. It was found that backspattered blood would deposit on the shooter's shirt sleeve irrespective of the weave pattern. Transferred blood was observed only on the fiber tops. This information was found to be useful in reconstruction of events in suicides as well as possible homicides.

影响政策执行的主要因素探析

政策执行是指政策方案被采纳之后,将政策内容付诸实施,转变为现实的过程。政策执行是政策过程中极其重要的一个环节,政策执行的好与差,直接关系到政策成败,而政策成败则关系到社会公共问题是否得到有效解决,从更深层次而言,涉及到社会利益分配的公正与否,因为公共政策本身是政府行为的直接产品,其本质是政府对全社会利益的权威性分配。从这角度上讲,政策执行比政策制定更为重要。政策执行过程中会遇到各种各样因素的干扰和影响,从而加剧政策执行工作的复杂性、艰巨性,使政策不能达到预期效
