Prompted by the ever‐increasing cesarean rate, this paper considers the interpretive disjunct between two significant strands of feminist analysis that have arisen in the last four decades as a consequence of the phenomenon of medicalized birth. In contrast to the dominant paradigm of bioethical “Principalism,” both modes of analysis, understood as “the critique of industrialized labor” and “the critique of idealized labor,” are attentive to the way in which social discourses inform bioethical deliberation and practice, but significantly diverge in the nature of their accounts. The “industrialization critique” understands the culture of medical intervention to be impelled by an “obstetric desire” to appropriate women's reproductive potency, whereas the “idealization critique” relates new mothers’ “low childbirth satisfaction” to a pernicious normative ideal propagated by the natural childbirth movement. This paper will explore the anatomy of both critiques and interrogate their fidelity to the phenomenological insight of the body as chiasm between material and ideal. I will argue that while the insights of the idealization critique are well grounded, we must exercise caution about the critique's tendency to reductively understand the embodied experience of labor as entirely discursively produced, a gesture that risks re‐performing the dematerialization of women often effected through obstetric intervention itself. 相似文献

While there is consistent evidence that initial levels of cognitive ability predict mortality, there is mixed evidence for a relationship between changes in cognition and mortality. There have been few studies that have examined whether the level and slope of cognitive performance is predictive of subsequent mortality from all causes or from cardiovascular disease, stroke, heart disease, respiratory disease, or cancer. This study aimed to assess whether the level and slope of cognitive ability were associated with all-cause or cause-specific mortality. A cohort of 896 community-based elderly people in Australia was interviewed four times over 12 years, with vital status followed for up to 17 years. Of these, 592 participants completed two or more interviews and were included in survival models of six mortality outcomes. Cognitive change in five domains of ability was estimated using latent growth models. Poorer initial processing speed or verbal fluency was significantly associated with greater all-cause and/or cardiovascular mortality. In addition, declines in global ability were associated with greater all-cause, cardiovascular, and heart disease mortality. Vocabulary and episodic memory were not associated with mortality, and none of the cognitive tests significantly predicted respiratory or cancer mortality. Initial levels of cognitive ability tended to be better predictors of subsequent mortality than were changes in ability. The results suggest that vascular events may be largely responsible for the overall relationship between cognition and mortality. 相似文献

The promotion of breastfeeding is an important focus of intervention for professionals working to improve infant health outcomes. Literature in this area focuses largely on 'choices' and 'barriers to breastfeeding'. It is our argument, however, that women's cultural context plays a key role in infant feeding 'choices'. In this article, we explore contested representations of infant feeding and infant feeding choices in public debates conducted on a large British parenting website. To sample dominant representations of infant feeding circulating in UK culture, two threads were chosen from the debating board of a busy online parenting community (105 and 99 individual posts, respectively). Participants on the threads were largely women. A feminist informed Foucauldian discourse analysis was used to deconstruct the intersecting constructions of gender, childhood and motherhood implicit in public discussions about infant feeding choices. We identify dominant constructions of women who breastfeed or bottle feed, social representations of both forms of infant feeding, and explore the relationship between constructions of infant feeding choices and constructions of 'good' or 'bad' motherhood. This analysis functions to trouble the individualist assumptions underpinning the notion of infant feeding 'choices', considering the cultural context within which British mothers 'choose' how to feed their babies. 相似文献

When someone flees their country and seeks the protection of another state, they usually have to describe what happened to make them afraid to return. This task requires many psychological processes, a key one being autobiographical memory. Memory for events of a specific time and place in one's personal past is the subject of a huge literature, much of it showing that recall is vulnerable to distortions and biases. We review selected areas of this literature, shedding light on some of the processes at work when someone seeks to be recognised as a refugee—in particular, the effects of emotion, including emotional disorder. We then turn to the differing types of memory styles seen in different cultures. Crucial to this area, we briefly examine the current literature on deception. Finally, we draw on the reviewed literature to present conclusions about the reliance on autobiographical memories in the asylum process. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

When humans learn that the presence of a cue predicts the likelihood of an outcome, they can exploit this learned predictiveness, such that formation of subsequent associations between that cue and new outcomes is facilitated. Could such enhanced selection for association arise early enough to facilitate low-level visual processing? In a test of this possibility, adult volunteers first engaged in a value-learning task involving faces that were differentially predictive of monetary wins or losses. Later, in a simple recognition task, these faces were briefly presented for a variable duration and then masked. The critical presentation duration needed to produce criterion-level recognition was measured to index the visual processing speed for each learned face. Critical duration was significantly shorter for stimuli with high learned predictiveness than for stimuli with low learned predictiveness, regardless of whether they were associated with wins or losses. These results show that neural mechanisms involved in predicting future outcomes are able to modulate visual processing efficiency, probably via cortical feedback processes. 相似文献

Wernicke's Encephalopathy is an acute neuro-psychiatric condition caused by an insufficient supply of thiamine (Vitamin B1) to the brain. If undiagnosed or inadequately treated, it is likely to proceed to Korsakoff's Syndrome. Wernicke's Encephalopathy can result from dietary deficiency alone and this form is usually successfully treated, with little chance of Korsakoff's Syndrome supervening. On the other hand, thiamine deficiency associated with alcohol misuse/dependence may require up to 1 gram of thiamine IV in the first 24 hours to be treated successfully. The reasons for this difference in treatment will be discussed. Thiamine diphosphate acts as a co-factor for a number of thiamine-dependent enzymes. Thiamine deficiency leads to a reduction in the activity of these enzymes, and this leads to alterations in mitochondrial activity, impairment of oxidative metabolism, decreased energy status and eventually selective neuronal death. The damage caused by the combination of thiamine deficiency and alcohol metabolism probably interferes with adequate thiamine transport at a number of sites in the body, including the blood-brain barrier, as well as causing damage to the apoenzymes which then require higher concentrations of thiamine to work normally. The accumulated damage is likely to render the use of oral thiamine therapeutically inadequate since the body is unable to produce high enough concentrations of thiamine in the blood to traverse the blood-brain barrier. Some individuals are probably genetically predisposed to develop Wernicke's. Long before individuals with alcohol misuse or dependence develop Wernicke's Encephalopathy the neurons and other cells of the body are functioning sub-optimally because of the inadequate supply of thiamine and the neurotoxic effect of alcohol. This relative deficiency initiates a series of pathological changes which accumulate and further interfere with the supply of thiamine and its utilisation at a time when the requirements are increased. The best treatment for Korsakoff's Syndrome is timely recognition of Wernicke's Encephalopathy and appropriate intervention and prevention. 相似文献

The present investigation evaluates the relationship between coping style, dispositional hope, and posttraumatic stress disorder (PTSD) and depression symptom severity in a trauma-exposed Veteran sample. Specifically, we evaluated the adaptive value of emotional avoidant and approach coping strategies and perceptions of hope in a sample of 209 trauma-exposed Veterans receiving outpatient mental health care at a VA facility. Participants completed a life events questionnaire and inventories assessing coping, dispositional hope, and PTSD and depression symptom severity. Hierarchical regression analyses were conducted controlling for relevant demographic variables. Greater levels of emotional avoidance and lower levels of emotional expression were significantly associated with increased PTSD and depression symptom severity. Dispositional hope was positively associated with depression symptoms only and perceptions of hope moderated the association between emotional avoidance coping and depression symptoms. Findings highlight the value of emotional coping strategies and perceptions of hope in posttraumatic adjustment. Specifically, employing coping techniques that encourage emotional expression may promote improved adjustment among trauma-exposed individuals, while reduced perceptions of hope and the use of avoidant coping strategies may place individuals at greater risk for depression following exposure to traumatic events. 相似文献

Previewing scenes briefly makes finding target objects more efficient when viewing is through a gaze-contingent window (windowed
viewing). In contrast, showing a preview of a randomly arranged search display does not benefit search efficiency when viewing
during search is of the full display. Here, we tested whether a scene preview is beneficial when the scene is fully visible
during search. Scene previews, when presented, were 250 ms in duration. During search, the scene was either fully visible
or windowed. A preview always provided an advantage, in terms of decreasing the time to initially fixate and respond to targets
and in terms of the total number of fixations. In windowed visibility, a preview reduced the distance of fixations from the
target position until at least the fourth fixation. In full visibility, previewing reduced the distance of the second fixation
but not of later fixations. The gist information derived from the initial glimpse of a scene allowed for placement of the
first one or two fixations at information-rich locations, but when nonfoveal information was available, subsequent eye movements
were only guided by online information. 相似文献

A pilot study of a brief group-based Acceptance and Commitment Therapy (ACT) intervention (12 two-hour sessions) was conducted with clients of public mental health services meeting four or more criteria for borderline personality disorder (BPD). Participants were randomly assigned to receive the ACT group intervention in addition to their current treatment (ACT + TAU; N = 21) or to continue with treatment as usual alone (TAU; N = 20). There was significantly more improvement from baseline for the ACT + TAU condition than the TAU condition on the primary outcome variable—self-rated BPD symptoms. The ACT + TAU gain was both clinically and statistically significant. The ACT + TAU condition also had significantly more positive change on anxiety and hopelessness, and on the following ACT consistent process variables: psychological flexibility, emotion regulation skills, mindfulness, and fear of emotions. For all but anxiety, the improvements for the ACT + TAU condition were significant, while the TAU condition had no significant changes on any measure. Follow-up was possible for only a small number of participants. The improvements gained by the ACT + TAU participants were maintained except for fear of emotions. Anxiety continued to improve, becoming significantly different from baseline at follow-up. Examination of mediators found that psychological flexibility, emotion regulation skills and mindfulness, but not less fear of emotions, mediated BPD symptoms. Psychological flexibility and emotion regulation skills also mediated hopelessness. There is a need for a larger trial, for comparison with other established treatments for BPD, and for conducting a trial of a longer intervention. Nonetheless, this pilot study suggests that a brief group-based ACT intervention may be a valuable addition to TAU for people with BPD symptoms in the public sector. 相似文献

The aim of the present study was to investigate the factors relating to non-adherence to warning signs about falling rocks from coastal cliff faces. Face-to-face interviews (n?=?62) in a naturalistic setting (in the vicinity of a high-risk rockfall area) were conducted to investigate attention to and comprehension of warning signs, as well as beliefs relating to non-adherence of the signage. It was found that, while most participants could correctly identify the danger in the area and had noticed the warning signage, less than half of the participants could correctly interpret the signage. The perception of danger did not differ significantly between the participants who had, or had not, entered the high-risk zone. Differences in knowledge and beliefs between local residents and visitors to the area were identified. It was concluded that the warning signs did not provide enough detail for people to make informed decisions about safe behaviours. Comprehension of the signage may have been hampered by a lack of prior-knowledge of the particular risk, a failure to think carefully about the situation (i.e. low-effort processing), and the pictorial representation on the signs misleading the participants as to the true danger. 相似文献
