融合与实践：20世纪初美国护士助产士的出现

通过梳理20世纪初期美国护士助产士出现的历史过程,分析其出现的推动因素。母婴高死亡率问题引发了产科医生与护士对于分娩的不同理解,并且分别在医院与家庭中开展助产实践。护士助产士融合了护理与助产实践,并与医生建立合作关系。在这个过程中,护士助产士良好地平衡了医生与护士之间的观念分歧,并且推动了护理专业范围的拓展。护士助产士的出现带来了对分娩观念的理性思辨,护士助产士的实践模式为未来中国发展助产士、提高母婴健康水平提供了历史借鉴。

     

Memory consolidation effects on memory stabilization and item integration in older adults

This study examined the differential effects of aging on consolidation processes that strengthen newly acquired memory traces in veridical form (memory stabilization) versus consolidation processes that are responsible for integrating these memory traces into an existing body of knowledge (item integration). Older adults learned 13 nonwords and were tested on their memory for the nonwords, and on whether these nonwords impacted upon processing of similar-sounding English words immediately and 24 hours later. Participants accurately recognized the nonwords immediately, but showed significant decreases in delayed recognition and recall. In comparison, the nonwords impacted upon processing of similar-sounding words only in the delayed test. Together, these findings suggest that memory consolidation processes may be more evident in item integration than memory stabilization processes for new declarative memories in older adults.     

张岱年哲学思想四题

就哲学理论的探讨而言,张岱年之哲学思想体系大致可以分为四个部分:一为"一本多级"之物本论;二为"真知三表"之经验论;三为"充生以达理"之人生论;四为"文化综合创新论"。它们呈现出张岱年哲学体系的主干,故亦可以成为其哲学体系的框架。     

Two mutations preventing PDZ-protein interactions of GluR1 have opposite effects on synaptic plasticity

The regulated trafficking of GluR1 contributes significantly to synaptic plasticity, but studies addressing the function of the GluR1 C-terminal PDZ-ligand domain in this process have produced conflicting results. Here, we resolve this conflict by showing that apparently similar C-terminal mutations of the GluR1 PDZ-ligand domain result in opposite physiological phenotypes during activity- and CamKII-induced synaptic plasticity.     

The effects of childbirth-related post-traumatic stress disorder on women and their relationships: a qualitative study

There is converging evidence that 1%-2% of women develop post-traumatic stress disorder (PTSD) as a result of childbirth. The current study aimed to explore the long-term effects of childbirth-related PTSD on women, their relationship with their partner and their relationship with their child. Semi-structured interviews were carried out with six women who reported clinically significant PTSD after birth, ranging from 7 months to 18 years beforehand. Interviews were transcribed and analysed using thematic analysis. Childbirth-related PTSD was found to have wide-ranging effects on women and their relationships. Women reported changes in physical well-being, mood and behaviour, social interaction, and fear of childbirth. Women reported negative effects on their relationship with their partner, including sexual dysfunction, disagreements and blame for events of birth. The mother-baby bond was also seriously affected. Nearly all women reported initial feelings of rejection towards the baby but this changed over time. Long-term, women seemed to have either avoidant or anxious attachments with their child. It is concluded that childbirth-related PTSD can have severe and lasting effects on women and their relationships with their partner and children. Further research is needed to compare this to normal difficulties experienced by women after having children.     

Young children's use of a delayed video representation to solve a retrieval problem pertaining to self

The experiments reported here were concerned with the development of delayed self-recognition. Children were videotaped playing a game and were marked covertly with a sticker on their forehead while doing so. The findings, of both a cross-sectional sample and a prospective longitudinal one, revealed that 3- but not 2.5-year-old children reached to remove this sticker reliably during video playback only after they had been trained to use the video to guide their search for an object that was not directly visible to the unaided eye. It appears that by 3 years of age children understand that their briefly delayed self video-representation is related to their present self. In contrast, while 2.5-year-olds can use delayed video information to locate objects in space that cannot be seen by the unaided eye, they cannot use this type of information to locate an object that pertains to a part of self that is not directly visible, such as a sticker on one's hair. The findings are discussed in terms of the emergence of an extended sense of self.
