Resilience to Loss in Bereaved Spouses, Bereaved Parents, and Bereaved Gay Men.

Recent research has indicated that many people faced with highly aversive events suffer only minor, transient disruptions in functioning and retain a capacity for positive affect and experiences. This article reports 2 studies that replicate and extend these findings among bereaved parents, spouses, and caregivers of a chronically ill life partner using a range of self-report and objective measures of adjustment. Resilience was evidenced in half of each bereaved sample when compared with matched, nonbereaved counterparts and 36% of the caregiver sample in a more conservative, repeated-measures ipsative comparison. Resilient individuals were not distinguished by the quality of their relationship with spouse/partner or caregiver burden but were rated more positively and as better adjusted by close friends.

The social parameter of "learned" helplessness: Its recognition and implications.

Reexamines experiments on learned helplessness that have been interpreted previously as involving a solitary person experiencing uncontrollable and inescapable events. It is suggested that the belief that the outcomes are uncontrollable precludes the possibility that control of the outcomes can be transferred to the experimental Ss. An alternative interpretation is that the outcomes in learned helplessness experiments, rather than being uncontrollable, are controlled by the experimenter. Helplessness could be reduced by transferring this control to Ss, giving them control over their contingencies. This analysis has implications regarding both the accuracy of depressed people's perceptions and the desirability of making depressed people perceive an internal locus of control. It is further suggested that depressed people should have more control over their contingencies. (34 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Remaining oil distribution in Ng3^3 bottom water reservoir of Lin 2-6 fault-block in Huimin depression and potential tapping in horizontal well

Oil reservoirs with secondary bottom water in Ng33 members (in Guantao formation, Paleogene system) of Lin2-6 fault block in Huimin depression (Bohai Bay Basin) have entered the late stage of ultra-high water-containing-exploitation. Oil exploita-tion from vertical wells is becoming more and more inefficient. The reservoir type, with water displacing oil and the remaining oil distribution are specifically studied in order to improve the efficiency of the recovery ratio. An integrated scheme for adjusting horizontal wells has been designed and the key technique of the scheme optimized. The study shows that: 1) the positive rhythm of fluvial depositional features is the internal cause of the flooding of oil reservoirs while water injection, injection-production patterns and accumulative petroleum production are the external causes; 2) oil-water driving patterns have transferred from edge water ad-vancing to bottom-water-coning; distribution of the remaining oil mainly concentrates in the upper rhythm and top of the middle rhythm in Ng33 members; 3) a great deal of remaining oil is enriched in high positions of faults, in axes of tiny structures, in stagna-tion areas among water-injection wells and oil-wells and in tectonic saddle areas with sparse wells. Compared with vertical wells, horizontal wells have advantages such as high recovery, high off-take potential, high critical output, large controlling areas and long time of bottom-water breakthrough.     

胶结物对东营凹陷储层砂岩弹性特征的影响

储层岩石的地震弹性属性是进行油气储层勘探及动态监测的基础。系统选取东营凹陷古近系各层段砂岩样品250块（以沙河街组为主）,在模拟储层条件下利用脉冲穿透法测试样品的纵、横波速度。样品在纵波速度一泊松比交汇图中表现出两种主要变化趋势,分别对应泥质与钙质胶结物的影响;在每个变化趋势中随泥质含量与钙质胶结物含量的增加,岩石结构从颗粒所构成的骨架支撑逐渐表现为基质支撑,弹性波能量的传播也从通过颗粒接触边界转变为通过岩石基质传播,这是使砂岩样品测试结果表现出两种截然不同变化趋势的主要原因,为利用岩石物理特性从地震资料中提取岩石结构、沉积与成岩特征的信息提供了依据。
