Psychological Distress in a Natural Disaster Introduction Among the many problems that humans encounter following a natural disaster is Post Traumatic Stress Disorder (PTSD). PTSD can result from natural disasters like floods, earthquakes, tsunamis, hurricanes, tornados among other frightening natural events that cause damage and result in serious injuries and loss of life. When humans are exposed to horrific natural disasters they may continue to carry the fearful events in their memories; those realistic recollections can haunt the individual to the point of causing serious psychological disorders. Hence, PTSD can become a very serious emotional problem that requires psychological help from professionals. This paper provides instances of PTSD research following natural disasters – and studies that delve into the dynamics of PTSD that resulted from natural disasters, including the terrible flooding in Thailand in 2000.

Youth unemployment rates in Armenia are at an all-time high, but what is leading to its increase? Unemployment rates in countries are defined by individuals who are currently jobless but are seeking active employment within the last four weeks (Bureau of Labor Statistics, 2009). It is particularly interesting to see such a high youth unemployment rate because statistics show that the general unemployment rate within adults in Armenia has decreased from 7.1% in 2007 to 5.9% in 2011 (Index Mundi, 2012) yet unemployment amongst the youth contuse unabated and shows no tendency to decline. Several negative things are correlated with youth unemployment. Examples in this include preventions of socializations in the labor market which lead to negative social consequences, cycles of dependence on parents and an increased likelihood of drug and or alcohol consumption (World Bank, 2007). The following paper will investigate possible results of unemployment in youth unemployment in Armenia and propose to test whether these variables still exist and, if so, to which extent.
