Keeping in view the general trend of interdependent arrival and service processes, it is presumed that random variables of arrival and service processes follow a bivariate poisson distribution and the server provides his services under general discipline of service rule in an infinitely large waiting space. In this paper, our central attention is to explore the probability generating functions using Rouche’s theorem in both cases of slower and faster arrival rates of the queueing model taken into consideration;which may be helpful for mathematicians and researchers for establishing significant performance measures of the model. Moreover, for the purpose of high-lighting the application aspect of our investigated result, very recently Maurya [1] has derived successfully the expected busy periods of the server in both cases of slower and faster arrival rates, which have also been presented by the end of this paper.展开更多
目的利用主客体互倚模型探讨克罗恩病患者及其配偶主观幸福感对婚姻调适的作用。方法采取方便抽样法,抽取南京市某3级甲等医院210对患者及配偶为研究对象,选用自制一般资料调查表、主观幸福感量表简表(Subjective Well-being Scale for ...目的利用主客体互倚模型探讨克罗恩病患者及其配偶主观幸福感对婚姻调适的作用。方法采取方便抽样法,抽取南京市某3级甲等医院210对患者及配偶为研究对象,选用自制一般资料调查表、主观幸福感量表简表(Subjective Well-being Scale for Chinese Citizens,SWBS-CC20)、Locke-Wollance婚姻调适测定(Locke-Wollance Marital Adjustment Test,LWMAT)对其进行调查。采用独立样本t检验和卡方检验比较夫妻主观幸福感和婚姻调适方面的差异,通过主客体互倚模型和Pearson分析法,分析夫妻双方主观幸福感对婚姻调适的影响。结果患者和配偶各自的主观幸福感均可以正向预测自身婚姻调适(β=0.67、0.71,P<0.01),即主体效应明显;同时,患者与配偶的主观幸福感均能正向预测对方的婚姻调适(β=0.47、0.46,P<0.01),即客体效应明显。结论克罗恩病患者及配偶的婚姻调适受自身及对方主观幸福感的交互影响,且主观幸福感与婚姻调适之间主体效应和客体效应显著。因此应将克罗恩病患者及配偶视为一个整体,关注夫妻双方的二元交互影响,积极探索以夫妻为中心的婚姻调适干预方案,对改善克罗恩病夫妻的心理适应有重要意义。展开更多
随着中国人口进入深度老龄化阶段,存在抑郁焦虑症状的老年人不断增加,老年人的心理健康问题日益凸显。基于婚姻的内在保护机制、主客体互倚模型和社会支持理论形成的综合分析框架,立足2020年CHARLS (China Health and Retirement Longit...随着中国人口进入深度老龄化阶段,存在抑郁焦虑症状的老年人不断增加,老年人的心理健康问题日益凸显。基于婚姻的内在保护机制、主客体互倚模型和社会支持理论形成的综合分析框架,立足2020年CHARLS (China Health and Retirement Longitudinal Study)数据,从计量维度分析婚姻状况对老年人抑郁程度的影响,以及子代支持(情感支持和经济支持)在其中的中介作用。结果显示,夫妻共同居住的老年人婚姻比其他婚姻类型(因工作原因分居、分开未离异、离异和丧偶)的老年人抑郁程度更低,且存在夫妻间抑郁情绪高度相关的情况;同时,已婚同居的老年人会得到更多的子代支持(包括情感支持和经济支持),这些子代支持有助于降低其抑郁程度。以此,为实现稳步提升老年人健康水平,促进实现健康老龄化国家战略提出了证据为本的政策指向。展开更多
