随着勘探程度的深入,为了扩大四川盆地天然气勘探领域、寻找新的勘探接替区,四川盆地的勘探区域由盆内逐渐向盆缘延伸。在这种背景下,川东北地区须家河组二段相继取得新的勘探成果,但在勘探开发过程中逐渐暴露了诸如区块之间气井产能差异大,储层的碎屑组分、结构及厚度、物性、孔隙结构差异明显等问题,制约了勘探开发的步伐。针对上述问题,根据岩芯观察描述、分析化验资料及测井解释成果,从沉积、成岩方面入手,对比剖析了川东北龙岗和营山地区须二段储层特征的差异性及其成因,认为远离物源区和高能水体的反复淘洗是造成储层差异性的首要因素,强烈的压实作用和多期石英加大对储层差异性起关键作用,自生绿泥石衬边胶结和长石选择性溶蚀最终决定了储层差异性。从而解释了气藏勘探开发中遇到的诸多问题,对有效指导该区的下一步勘探开发工作具有重要意义。  相似文献

Transformational leaders are known to inspire and motivate their followers, thereby leading to enhanced job satisfaction. Job satisfaction is an intellectual concept regarding individuals’ attitudes toward their jobs. This study asserts that the underlying mechanisms for transformational leadership to affect employee satisfaction are trust in the community, including the leader (that is, organization) and trust in the self, namely self‐efficacy. Leadership is specifically associated with continual transformations in the higher educational context, and collectivist cultures may manifest different processes underlying the transformational leadership–satisfaction relationship. This study investigated the mediating effects of trust and self‐efficacy on the relationship between transformational leadership and job satisfaction. The study sample included academicians from a nonprofit higher education institution in Turkey. The data were analyzed using structural equation modeling. The results showed that the relationship between transformational leadership and job satisfaction is fully mediated by both trust and self‐efficacy. The mediator effect of trust was shown to be stronger than self‐efficacy, which is assumed to be the result of the cultural context. The results are discussed in the context of employee satisfaction and cultural determinants of employee satisfaction.  相似文献

在中国历史和现实中,谈民族无论如何是和血缘分不开的.中国人有认祖归宗的传统,实质上就是一种血缘认同.基于此,我们对民族概念的界定,也应该从实际出发,回归到中国社会一般理解和运用的那种含义,而不必去跟随外来话语莫衷一是.民族具有血缘性,除了一部分真实之外,更大部分是出于认同需要的“血缘拟制”.民族过程的基本倾向之一是民族的血缘性不断下降,而反映这种变化的直观表现就是族际通婚.改革开放是中国各民族交往交流交融最为深刻的时期,也是中国各民族的血缘性得到最为深刻改造的时期.无论是对照以往的调查资料还是经验观察,都可知当前我国族际婚姻的数量在增多,范围在扩大.族际通婚的增加淡化了各民族自身的血缘性,却增添了各民族之间血缘的联通性.各民族通过族际通婚将自己的血缘扩散到其他民族的过程,也就是中华各民族之间的血缘联系得到更为巩固的过程.  相似文献

Objectives: The aim of the current article was to provide an overview of literature on sexual function and sexual difficulties in older adults. Method: The authors conducted a narrative review of papers published in English between January 2005 and July 2015 based on an extensive search in PsycINFO. Results: The review showed that although common biological changes may adversely affect sexual function in old age, sexual experience seems to also be affected by psychological and interpersonal factors. Conclusions: Greater life expectancy and better medical care will result in older individuals with chronic diseases living longer. The need for help to cope with changes in sexual health is likely to increase in older adults, as sexuality may be negatively affected through several pathways.  相似文献

Background

Following childbirth, a vast number of women experience some degree of mood swings, while some experience symptoms of postpartum posttraumatic stress disorder.

Aim

Using a biopsychosocial model, the primary aim of this study was to identify predictors of posttraumatic stress disorder and its symptomatology following childbirth.

Methods

This observational, longitudinal study included 372 postpartum women. In order to explore biopsychosocial predictors, participants completed several questionnaires 3–5 days after childbirth: the Impact of Events Scale Revised, the Big Five Inventory, The Edinburgh Postnatal Depression Scale, breastfeeding practice and social and demographic factors. Six to nine weeks after childbirth, participants re-completed the questionnaires regarding psychiatric symptomatology and breastfeeding practice.

Findings

Using a multivariate level of analysis, the predictors that increased the likelihood of postpartum posttraumatic stress disorder symptomatology at the first study phase were: emergency caesarean section (odds ratio 2.48; confidence interval 1.13–5.43) and neuroticism personality trait (odds ratio 1.12; confidence interval 1.05–1.20). The predictor that increased the likelihood of posttraumatic stress disorder symptomatology at the second study phase was the baseline Impact of Events Scale Revised score (odds ratio 12.55; confidence interval 4.06–38.81). Predictors that decreased the likelihood of symptomatology at the second study phase were life in a nuclear family (odds ratio 0.27; confidence interval 0.09–0.77) and life in a city (odds ratio 0.29; confidence interval 0.09–0.94).

Conclusion

Biopsychosocial theory is applicable to postpartum psychiatric disorders. In addition to screening for depression amongst postpartum women, there is a need to include other postpartum psychiatric symptomatology screenings in routine practice.  相似文献

中国养老保险缴费对消费和储蓄的影响   总被引:2,自引:0,他引:2  
考虑到家庭可能面临信贷约束,同时可能有目标储蓄的动机,当期养老金缴费可能会减少当期可支配收入,进而抑制消费,并可能提高储蓄率。使用城镇住户调查2002—2009年9省市的数据,利用养老保险缴费率和养老保险参与率的城市差别随时间的变化,构建家庭养老金缴费的工具变量,实证研究发现:在2006年之前,尽管增加养老保险覆盖率本身有助于刺激消费,在给定缴费前的收入水平以及养老保险覆盖状态时,提高养老金缴费率会显著抑制缴费家庭的消费。另外,养老保险缴费负担对总消费的影响主要也是负面的。  相似文献

In this article we examine the encounter between global human rights ideas and domestic discourses of civil rights and social justice, focusing on processes of translation and adaptation of women's human rights in two ethnographic sites in New York City. The first site is a citywide coalition working for the adoption of a New York City human rights ordinance. The second site is an advocacy organization working on domestic violence issues. We find that the local adoption of human rights in New York City – the ‘domestication’ of human rights – takes place in two central sites: law and social movement. We further find that the process of translation takes place unevenly in the two sites, and it is driven primarily by the actors, mechanisms and technologies in the social movement arena. Overall, we witness the emergence of a domestic human rights movement as a new counter‐hegemonic space, characterized by multiplicity in meanings, ideological heterogeneity and ambivalence from those engaged in its construction.  相似文献

The purpose of this article is to develop a Monte-Carlo simulation algorithm for computing mean time to failure (MTTF) of weighted-k-out-of-n:G and linear consecutive-weighted-k-out-of-n:G systems. Our algorithm is based on the use of appropriately defined stochastic process which represents the total weight of the system at time t. These stochastic processes are explicitly defined and used along with the ordered component lifetimes to simulate MTTF of the systems with weighted components.  相似文献
