While much of literature on place attachment describes it as an affective bond between a (young) person and place, with positive psychosocial consequences such as identification, rootedness and belonging, some authors are cautious and stress that an enhanced attachment to place, termed “territoriality”, may have negative consequences such as hostility towards outsiders and a sense of non-belonging elsewhere. In this paper, I ask how we should understand this difference and how the analysis of young people's emotional geographies of (in)security can bring light to this question. The paper finds that emotional geographies of (in)security are instrumental in understanding how a “positive” attachment to place may lead to a “negative” attachment to territory, how some young people emotionally attach to places and some are inclined to claim these places against outsiders (and also at the expense of other members of the community). This explicit appropriation of public spaces in the home neighbourhood is co-constituted by feeling secure inside and insecure outside the area. Territoriality may be a response to or an expression of ontological insecurity and of the inner unease that prompts them to strange avoidance and contorted strategies for manipulating spaces and setting boundaries designed to secure the self.  相似文献

In this paper the city of Copenhagen is used as a starting point to highlight some critical historical events, both concerning the exchange of ideas between the physicist Wolfgang Pauli and C.G. Jung and the history of psychotherapy in Scandinavia. Pauli's years in Copenhagen under the influence of Niels Bohr and his philosophy prepared him mentally to receiveC.G. Jung's ideas. The paper also recounts the one occasion that Jung was in Scandinavia, attending the 9th conference of the General Medical Society for Psychotherapy in Copenhagen, just before going to New York in 1937 to give his final seminars on Pauli's dreams. The reason for focusing on these particular events is that they also constitute part of the history of the reception of psychodynamic psychology in Sweden and Scandinavia.  相似文献

The process that community based participatory research (CBPR) implementation takes in indigenous community contexts has serious implications for health intervention outcomes and sustainability. An evaluation of the Elluam Tungiinun (Towards Wellness) Project aimed to explore the experience of a Yup'ik Alaska Native community engaged within a CBPR process and describe the effects of CBPR process implementation from an indigenous community member perspective. CBPR is acknowledged as an effective strategy for engaging American Indian and Alaska Native communities in research process, but we still know very little about the experience from a local, community member perspective. What are the perceived outcomes of participation in CBPR from a local, community member perspective? Qualitative methods were used to elicit community member perspectives of participation in a CBPR process engaged with one Yup'ik community in southwest Alaska. Results focus on community member perceptions of CBPR implementation, involvement in the process and partnership, ownership of the project with outcomes observed and perceived at the community, family and individual levels, and challenges. A discussion of findings demonstrates how ownership of the intervention arose from a translational and indigenizing process initiated by the community that was supported and enhanced through the implementation of CBPR. Community member perspectives of their participation in the research reveal important process points that stand to contribute meaningfully to implementation science for interventions developed by and for indigenous and other minority and culturally diverse peoples.  相似文献

Adolescent risk-taking behavior has been associated with age-related changes in striatal activation to incentives. Previous cross-sectional studies have shown both increased and decreased striatal activation to incentives for adolescents compared to adults. The monetary incentive delay (MID) task, designed to assess functional brain activation in anticipation of reward, has been used extensively to examine striatal activation in both adult and adolescent populations. The current study used this task with a longitudinal approach across mid-adolescence and late adolescence/early adulthood. Twenty-two participants (13 male) were studied using the MID task at two time-points, once in mid-adolescence (mean age = 16.11; SD = 1.44) and a second time in late adolescence/early adulthood (mean age = 20.14; SD = .67). Results revealed greater striatal activation with increased age in high- compared to low-incentive contexts (incentive magnitude), for gain as well as for loss trials (incentive valence). Results extend cross-sectional findings and show reduced striatal engagement in adolescence compared to adulthood during preparation for action in an incentive context.  相似文献

Most contemporary theologians have distanced themselves from views that identify the image of God with a capacity or a set of capacities that humans have. This article examines three arguments against the structural view and finds them wanting. The first argument is that the structural view entails mind/body dualism and dualism is no longer viable given neuroscience and contemporary philosophy. Against this, I argue that contemporary forms of dualism are able to circumvent such worries and are at least prima facie plausible. The second claim is that structural views end up disvaluing the human body and our relatedness. Here, I argue that neither the structural view nor dualism has such consequences. The third issue consists of various evolutionary worries that have to do with the lack of a clear‐cut boundary between human capacities and the capacities of nonhuman animals. As a response, the article argues that although there might not be a clear‐cut set of capacities that all humans share, we could still have a notion of human distinctiveness that is sufficient for the structural image of God.  相似文献

铬是人体的一种必需微量元素,大量体内研究证实三价铬与机体血糖的调节密切相关,许多体外研究表明糖尿病患者的铬含量发生了变化,作为葡萄糖耐量因子一部分,其缺乏与糖尿病发病及糖尿病并发症的发生有密切的关系,但作用机制尚未完全明确。研究表明,三价铬离子复合物除了可与胰岛素受体直接结合起作用外,还可以通过激活AMPK激酶来降低细胞膜胆固醇含量,改善细胞骨架功能,促进葡萄糖吸收。本文就三价铬的作用及其对糖脂代谢的影响做一阐述。此外,大量实验表明三价铬无论在体内、体外实验中均没有显示出基因毒性。  相似文献

观察阿卡波糖、二甲双胍联合胰岛素类似物治疗肥胖2型糖尿病的短期疗效。将60例符合标准患者随机分为观察组和对照组各30例,均给予重组甘精胰岛素联合赖脯胰岛素强化治疗控制血糖,观察组同时给予阿卡波糖及二甲双胍口服,出院时进行疗效评价。观察组血糖达标时间、胰岛素用量少于对照组,餐时胰岛素停用比例大于对照组,差异有统计学意义(P<0.05);两组患者出院时体重较入院时均有所下降,观察组较对照组体重变化更明显(P<0.01)。阿卡波糖、二甲双胍联合胰岛素类似物治疗方案,可作为初诊肥胖2型糖尿病治疗的理想方法之一。  相似文献

随着聚乙二醇化干扰素(IFN)的普及应用和慢性丙型肝炎规范化治疗的开展,其治愈率不断提高.但疗效不佳的慢性丙型肝炎患者不断积累,难治性慢性丙型肝炎患者成为临床医生必须面对的挑战.难治性丙型肝炎患者应当分为两类,第一类为“难治疗”性慢性丙型肝炎患者,该类患者由于宿主条件限制,不能耐受IFN联合利巴韦林(RBV)的标准治疗,如儿童和老年人、慢性肾功能衰竭患者等.第二类为“难治愈”性慢性丙型肝炎患者,该类患者可以耐受标准治疗方案,但按照应答指导的治疗原则(RGT)治疗后,效果仍然不佳或复发.本文就近年关于难治性丙型肝炎的研究进展,从难治性丙型肝炎的定义、机制、治疗诸方面作一综述.  相似文献

This study examined English- and Spanish-speaking psychologists’ and psychiatrists’ opinions regarding problematic, absent and stigmatizing diagnoses in current mental disorders classifications (ICD-10 and DSM-IV), and their perceived need for a national classification of mental disorders. Answers to open-ended questions included in WHO-WPA and WHO-IUPsyS surveys were examined using an inductive content-analysis method. A total of 3,222 participants from 35 countries were included. The most problematic diagnostic group was personality disorders, especially among psychiatrists, because of poor validity and lack of specificity. Complex posttraumatic stress disorder was the most frequent diagnosis suggested for inclusion, mainly by psychologists, to better account for the distinct processes and consequences of complex trauma. Schizophrenia was the diagnosis most frequently identified as stigmatizing, particularly by psychiatrists, due to lack of public understanding or knowledge about the diagnosis. Of the 14.4% of participants who perceived a need for a national classification system, two-thirds were from Africa or Latin America. The rationales provided were that mental disorders classifications should consider cultural and socio-historical diversity in the expression of psychopathology, differences in the perception of what is and is not pathological in different nations, and the existence of culture-bound syndromes. Implications for ICD-11 development and dissemination are discussed.  相似文献
