Post traumatic-stress disorder is a result of exposure to traumatic events. Such events include sexual assault, warfare, serious injury, threats from imminent death. Diagnosis for it includes symptoms such as disturbing recurring flashbacks, avoidance of memories of the event, and hyperarousal and it usually continues for at least one month after the traumatic event. When people experience numerous traumatic events, this situation occurs. Sometimes it is very difficult to deal with the situation when the trauma is extreme.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
