Abstract
Objectives Early physical and mental experiences from family of origin and parents might influence individuals' later adulthood quality of life (QOL). The present study was undertaken to examine the inter-relationships among function of family of origin, resilience, and current quality of life in a T2DM sample from China. Methods Three hundred T2DM participants were included in this investigation. A Chinese version of Connor-Davidson Resilience Scale 25, an APGAR family functioning scale, and a Diabetes Specificity Quality of Life Scale were used to assess the levels of mental resilience, function of family of origin, and QOL of these patients, respectively. Multiple stepwise regression analysis was performed to identify the predictors of QOL. A 3-step composite analysis was used to examine the predicted mediating effect. Results QOL total score was negatively related to resilience (r = - .299, p < 0.01) and family function (r = - .246, p < 0.01). In contrast, a significantly positive correlation between resilience and family function (r = .302, p < 0.01) was found. Two subscales of resilience (strength and optimism) and function of family of origin explained an additional 4.5% of the variance in QOL changes after controlling for demographic variables. Resilience had a 26.3% mediating effect between function of family of origin and current QOL. Conclusion In conclusion, the present work suggested a synthetic and stable association between function of family of origin and QOL level in the later life in a sample of Chinese T2DM population, with resilience acting as a mediating factor. Adult individuals who have grown up in an unfavorable family setting may be low in mental resilience, and would have worse QOL in their mid- and later life, especially when they are confronted with certain adversity or stress, such as having diabetes.

Abstract
In the fifth generation (5G) networks, isolated logical slices are formed by the same infrastructure, and spectrum resource. In the coverage regions of the sharing access points (APs), device to device (D2D) communication can occur among different slices, i.e., onemobile terminal (MT) acts as aD2D relay for another MT serving by a different slice. Since the slices, and the MTs are selfish who will not help others voluntarily, this paper proposes a two-layered incentive scheme to stimulate cooperation. To achieve this, two resource allocating problems of the proposed incentive scheme are formulated which introducing the slices,' and the MTs' cooperative activities, thus more resources will be allocated to the cooperative slices, and MTs as reward. Since the slices,' and the MTs' instantaneous resource allocations can not be obtained by the two optimal problems, the incentive scheduling algorithms of the slices, and theMTs are designed. Finally, we define the isolation indexes to evaluate slice isolation when carrying out cooperation. By simulating, it is proved that the proposed incentive scheme can stimulate cooperation efficiently, since the throughputs of the cooperative slices, and MTs are both improved. And the proposed incentive scheme is helpful for the slices, and the MTs to meet the statistical service quality requirements, and brings the bad effect to the instantaneous service quality requirements.
