Many studies argue that third-party guarantees, such as those of the United Nations, increase the chances that belligerents will sign peace agreements, but it is unclear how third-party involvement affects the implementation of such agreements. We unpack the relationship between UN involvement and peace agreement success by focusing on the risk of defections during the peace accord implementation phase. We argue that two types of commitment problems, namely involuntary and voluntary defections, emerge from the characteristics of the peace process itself as well as from new opportunities available to rebel groups. We expect that shifts in relative power and polarized voting lead to lower implementation scores overall, but that the deployment of UN troops has a mitigating effect, thereby increasing the prospects of sustainable peace agreements. Using data from the Peace Accords Matrix Implementation Dataset from 1989 to 2010 and personnel commitments to UN peacekeeping operations, we find evidence that large UN missions are better placed to support the implementation and longevity of the peace process.
Social security for the disabled has made headway in both academic studies and institution building as the survivaand development of disabled persons has gained increasing attention from the government and society.However,a close examination reveals an evident shortcoming in the academic community,in that more emphasis is put on problems and solutions while basic theories are usually neglected.Particularly,institution building ofsocial security for the disabled,e.g.,security system reconstruction,modeloptions,and solutions for 相似文献
Learned helplessness (LH) may mediate the link between violence exposure and mental disorders in battered women. This study
evaluated the contribution of LH to Posttraumatic Stress Disorder (PTSD) and major depression (MDD) in women with prolonged
exposure to partner violence in 101 residents of shelters for battered women in Israel. DSM-IV axis-I disorders were assessed
by a structured clinical interview. Self-report questionnaires evaluated exposure to violence, symptoms of PTSD and depression,
LH, history of child abuse, SES and the extent of male-dominance and prejudice against women in the participants prior socialization
background. LH significantly mediated the effect of violence on PTSD and depression symptoms. Male-dominated background contributed
to LH. Thus, LH may increase the risk of mental disorders in battered women and should be addressed in interventions designed
to reduce the burden of mental illness in this population. 相似文献
