Impaired social functioning is a defining characteristic of schizophrenia (SZ) and social cognition deficits affect interpersonal relations and outcomes such as independent living, vocational functioning and employment status. Some studies have demonstrated important socio-cultural aspects of SZ, for instance by examining experiences of SZ in different developing countries and among minority groups in the Western world. The socio-cultural context is central to understanding patients’ experiences in any society, however. Using an anthropological approach, we use qualitative research methods to examine patient perspectives on SZ. Sampling and Methods: In-depth qualitative interviews are carried out with SZ patients in France, the UK and the USA representing diversity in Western mental health systems. Results: To the participants, the most important QoL aspects are close relations and support from loved ones, a safe home and comfort zone, and meaningful daily activities. Normalisation and independence act as central themes to patients’ QoL and hopes for social integration. The participants need a buffer zone consisting of social relations, a home and daily occupation that is flexible and may balance issues of equality/inequality, abnormality/normality, and dependence/independence. Conclusion: By using participatory methods, PWS may be involved in shaping their own treatment and recovery plans based on what is subjectively meaningful and beneficial to their mental health. QoL and functioning are closely linked to the socio-cultural context in which health care structures go hand in hand with health care cultures that shape patients’ expectations and preferences.展开更多

Through virtualization, multiple customized virtual networks(VNs), requested by users, are allowed to coexist on the underlying substrate networks(SNs). In addition, the virtualization scheme contributes to sharing underlying physical resources simultaneously and seamlessly. However, multiple technical issues still stand in the way of NV successful implementation. One key technical issue is virtual network embedding(VNE), known as the resource allocation problem for NV. This paper conducts a survey of embedding algorithms for VNE problem. At first, the NV business model for VNE problem is presented. Then, the latest VNE problem description is presented. Main performance metrics for evaluating embedding algorithms are also involved. Afterwards, existing VNE algorithms are detailed, according to the novel proposed category approach. Next, key future research aspects of embedding algorithms are listed out. Finally, the paper is briefly concluded.展开更多
