Assembly Resolution. 20 June had previously been commemorated as "African Refugee Day" in a number of African countries. In the United Kingdom World Refugee Day is celebrated as part of Refugee Week. Refugee Week is a nationwide festival designed to promote understanding and to celebrate the cultural contributions of refugees, and features many events such as music, dance and theatre. In the Roman Catholic Church, the World Day of Migrants and Refugees is celebrated in January each year, since instituted in 1914 by Pope Pius X. Issues Protracted displacement Displacement is a long lasting reality for most refugees. Two-thirds of all refugees around the world have been displaced for over three years, which is known as being in 'protracted displacement'. 50% of refugees—around 10 million people—have been displaced for over ten years. Protracted displacement can lead to detrimental effects on refugee employment and refugee workforce integration, exacerbating the effect of the canvas ceiling. Protracted displacement leads to skills to atrophy, leading qualifications and experiences to be outdated and incompatible to the changing working environments of receiving countries by the time refugees resettle. The Overseas Development Institute has found that aid programmes need to move from short-term models of assistance (such as food or cash handouts) to more sustainable long-term programmes that help refugees become more self-reliant. This can involve tackling difficult legal and economic environments, by improving social services, job opportunities and laws. Medical problems Refugees typically report poorer levels of health, compared to other immigrants and the non-immigrant population. PTSD Apart from physical wounds or starvation, a large percentage of refugees develop symptoms of post-traumatic stress disorder (PTSD), and show post-traumatic stress symptoms (PTSS) or depression. These long-term mental problems can severely impede the functionality of the person in everyday situations; it makes matters even worse for displaced persons who are confronted with a new environment and challenging situations. They are also at high risk for suicide. Among other symptoms, post-traumatic stress disorder involves anxiety, over-alertness, sleeplessness, chronic fatigue syndrome, motor difficulties, failing short term memory, amnesia, nightmares and sleep-paralysis. Flashbacks are characteristic to the disorder: the patient experiences the traumatic event, or pieces of it, again and again. Depression is also characteristic for PTSD-patients and may also occur without accompanying PTSD. PTSD was diagnosed in 34.1% of Palestinian children, most of whom were refugees, males, and working. The participants were 1,000 children aged 12 to 16 years from
