Within the last decade, there has been a sharp global rise in the number of young people identifying as transgender. More recently, there appears to be an increase in the numbers of young people detransitioning or returning to identifying with their natal sex after pursuing medical transition. A case is presented of a young woman who pursued a gender transition and returned to identifying as female after almost two years on testosterone. The author considers and critiques the affirmative model of care for gender dysphoric youth in light of this case.  相似文献

“健康环境悖论”是指在受欺负水平相对较低的环境中,受欺负个体有更多的适应问题。通过梳理相关实证研究,本文从人际与认知两大方面分析健康环境悖论的发生机制。人际机制强调健康环境会影响同伴群体对于受欺负者的态度和受欺负者的友谊,这些不良的人际关系进一步加剧受欺负者的适应困难。认知机制认为健康环境会通过向上的社会比较和消极归因方式,影响受欺负者的适应问题。最后,我们讨论了中国文化背景下“健康环境悖论”的适用性问题、未来研究的发展方向和对于干预实践的建议。  相似文献

IntroductionAs gene therapy entails potential drawbacks, studies are needed in order to know people's opinions regarding its use.ObjectivesThe present study examined French people's positions regarding somatic gene therapy.MethodA sample of 224 adults living in various areas in France was presented with 32 realistic scenarios that were created by orthogonally combining the levels of four factors: the type of illness (e.g., hemophilia), the probability of transmission of the pathogenic gene, the technique used (e.g., transfer of a functional gene just after birth), and le probability of success of the therapy.ResultsThrough cluster analysis, six qualitatively different positions were found: Never very acceptable (8% of the sample, mostly males and more educated people), Legalist (17%, mostly people who have been informed of the legal and technical aspects of the therapy), Depends on the chances of success (18%), Fully acceptable after birth (5%), Fully acceptable before birth (8%), and Quite always acceptable (33%, mostly older people with children).ConclusionAlthough it has some few detractors, the recourse to gene therapy seems to be well accepted by a majority of the participants, and this high level of acceptation hold whether the pathology considered is hemophilia, immunodeficiency, propensity to develop cancer, or cardiovascular pathology.  相似文献

This paper explores how nostalgia and collective memory are materialised, imagined, curated and orchestrated through the archive. Drawing upon the example of the Marks and Spencer's (M&S) archive, we argue that archives, particularly those containing objects, command nostalgia. They re-appropriate objects, memories and their histories into contemporary narratives. This paper adds to a body of work within and beyond geography and sociology exploring the potency and creativity of everyday materials and their ability to produce, imagine and memorialise affinities between people, places and past times. This raises questions about the politics of memory, the authenticity of objects and the nostalgic imaginaries they enliven, what we discuss as ‘faux nostalgia’. We illustrate how M&S is part of collective British memory, promoting middle-class ideals of British family life. The archive and objects on display materialise such imaginaries, creating a yearning for the spirit, values and opportunities of times gone by; interweaving them into contemporary narratives of family life to create unattainable ideals. We reflect upon the biographies of three objects from the archive: a music sheet, an unsewn button and a replica tin. By making these objects central to our account, we illustrate how they materialise and recollect nostalgia through the archive.  相似文献

This investigation examined whether impairment in configural processing could explain deficits in face emotion recognition in people with Parkinson’s disease (PD). Stimuli from the Radboud Faces Database were used to compare recognition of four negative emotion expressions by older adults with PD (n = 16) and matched controls (n = 17). Participants were tasked with categorizing emotional expressions from upright and inverted whole faces and facial composites; it is difficult to derive configural information from these two types of stimuli so featural processing should play a larger than usual role in accurate recognition of emotional expressions. We found that the PD group were impaired relative to controls in recognizing anger, disgust and fearful expressions in upright faces. Then, consistent with a configural processing deficit, participants with PD showed no composite effect when attempting to identify facial expressions of anger, disgust and fear. A face inversion effect, however, was observed in the performance of all participants in both the whole faces and facial composites tasks. These findings can be explained in terms of a configural processing deficit if it is assumed that the disruption caused by facial composites was specific to configural processing, whereas inversion reduced performance by making it difficult to derive both featural and configural information from faces.  相似文献

Early childhood educators engage in complex and emotional work in their professional role educating and caring for children aged from birth to five years. The aim of this paper is to promote autoethnography as a most suitable method of understanding the role emotions play in the actualisation of young children's participation rights in early childhood education services. The author is a practising educator and draws upon a specific auto-ethnographic account of practice, the story of Sarah, as the focus of this paper to explore the emotional intensity of relationships in early childhood education. Autoethnography is discussed as a method to sit alongside ‘traditional’ ethnographic research to provide a deep understanding of the role of the educator embracing and enacting a rights approach in their work and what influences their decision making. In conclusion the author suggests autoethnography is a useful reflexive tool for educators to consider the role of emotions as a catalyst for change to ensure the actualisation of children's participation rights in daily practice in early childhood education.  相似文献

以310名幼儿父亲为研究对象,采用流行病调查中心抑郁量表、父母教养能力感量表的教养效能感分问卷、父母教养方式评价量表和Conners儿童行为问卷,考察父亲教养效能感和教养方式在父亲抑郁与幼儿问题行为间的中介作用。结果显示:(1)父亲抑郁、专制粗暴、情感联系和幼儿问题行为两两之间均显著正相关,父亲教养效能感、民主关怀、宽容理解两两之间均显著正相关,父亲教养效能感、民主关怀、宽容理解分别与父亲抑郁、专制粗暴、情感联系和幼儿问题行为两两之间显著负相关;(2)父亲抑郁对幼儿问题行为具有显著的正向预测作用;(3)父亲教养效能感和自身的民主关怀、专制粗暴、情感联系不仅分别在父亲抑郁与幼儿问题行为之间起部分中介作用,而且在父亲抑郁与幼儿问题行为之间起链式中介作用。  相似文献

Uninsured populations have poor treatment engagement and are less likely to receive evidence-based interventions for depression. The objective of the current study was to retrospectively examine depression screening, diagnosis, and treatment patterns among uninsured patients in primary care. Study sample included all patients (N = 11,803) seen in nine community-based clinics. Key variables included depression screener and/or a depression diagnosis, anti-depressant initiation, behavioral health visits, and patient follow up measures. Treatment patterns from the subsample of patients diagnosed with depression were analyzed by collecting the number of behavioral health visits and antidepressant use six months (180 days) following the diagnosis. Utilization of the depression screening tool was high (67%, n = 7,935) and 24% (n = 2,789) of the patients had a diagnosis of depression, however, more than half of the patients with a depression diagnosis did not have a recorded treatment plan (n = 1,474). The odds of anti-depressant use and behavioral visits for Hispanic patients were significantly greater than for Non-Hispanic patients. Universal screening with brief measures in primary care is improving, however, guideline-concordant depression treatment remains elusive for uninsured populations.  相似文献

Cognitive inhibition has been suggested to deteriorate in Alzheimer’s disease. While numerous studies with different experimental paradigms found evidence on impaired inhibition in attention and memory, evidence in favour of intact memory inhibition has been reported with regard to the phenomenon of retrieval-induced forgetting (Moulin et al., 2002). Here, we adapted the previously used paradigm in order to reduce the contribution of non-inhibitory processes and examined whether retrieval-induced forgetting could still be observed in a sample of participants with diagnosed Alzheimer’s disease. In contrast to the previous finding, we found that retrieval-induced forgetting only occurred in an age-matched control group. These results suggest that inhibitory deficits in Alzheimer’s disease also generalize to memory inhibition that resolves interference occurring during retrieval, whereas effects of retrieval-induced forgetting may still occur when non-inhibitory causes, such as, blocking by previously retrieved content, are not precluded.  相似文献
