Many women living with HIV/AIDS (WL-HIV/AIDS) experience significant mental distress. Although creative arts strategies are well positioned to help support women by inspiring creativity and meaning-making, few arts programs have been implemented and evaluated with this population. The authors conducted a photography project with 30 WL-HIV/AIDS from three United States cities. Participants took pictures to capture their lives with HIV/AIDS and described their photos and stories in group and individual sessions. Using thematic analysis, the authors identified that the project supported women’s mental health in four ways by facilitating empowerment and helping women to express themselves, address their mental health with new tools like photography, and process past traumas. Photography projects may help WL-HIV/AIDS understand and manage their mental health.  相似文献

The aim of the current vignette study is to map the style, type, and themes of questions that are asked when assessing the credibility of asylum seekers' claims. Sixty‐five officials from the Swedish Migration Agency (Migrationsverket ), were asked to respond to one out of four different vignettes that contained fictitious asylum narratives. Each vignette presented the types of problems often encountered by officials at the migration board. Two of the vignettes contained no evidence of the origin of the asylum seeker. The other two contained no evidence for the claim of persecution. The asylum officials were asked to formulate five questions that would help them to assess the veracity of the applicant's claim. Our analyses showed that they mainly formulated open questions in an information gathering style. A thematic analysis of the questions revealed that when a claim about origin was assessed, asylum officials mostly asked questions about life in the country of origin, identity documents, and the flight to Europe. When the claim about persecution was assessed, in contrast, asylum officials mostly formulated case‐specific questions (e.g., how the applicant was arrested). Hence, when the credibility of claims about origin is assessed, there seems to be a typical set of questions that asylum officials use. The asylum officials seem to assume that if the applicant is truly originating from a specific country or area, he or she should have ample knowledge about that area, its customs, and frequently encountered objects.  相似文献

Abstract

This article addresses the question whether skiing as a nature sport enables practitioners to develop a rapport with nature, or rather estranges and insulates them from their mountainous ambiance. To address this question, I analyse a recent skiing movie (Turist, 2014) from a psychoanalytical perspective (skiing as a quest for self-knowledge and as therapy) and from a neuro-scientific perspective (ski resorts as laboratory settings for testing physical and psychic responses to a variety of cues). I conclude that Jean-Paul Sartre’s classical but egocentric account of his skiing experiences disavows the technicity involved in contemporary skiing as a sportive practice for the affluent masses, which actually represents an urbanisation of the sublime, symptomatic for the current era (the anthropocene).  相似文献

In this paper, we present the special relationship between Catholicism and Latin American history, as seen by a Latin American thinker, Alberto Methol Ferré (Uruguay, 1919–2009). It is difficult to classify Alberto Methol Ferré within a specific discipline, due to the variety of the issues that he addressed: from Theology to Philosophy, from History to Politics and Geopolitics. Closely connected to his own time, he was fully engaged with the challenging features of the century he lived in. In this article, we shall first look into Methol Ferre's intellectual sources and examine his ideas on God and on people, in particular Latin American people. We shall then explore his theological interpretation of Latin American history and sketch a perspective of the relationship between the Catholic Church and Latin America, as he perceived it.  相似文献

For over 300 years, the humble triangle has served as the paradigmatic example of the problem of abstraction. How can we have the idea of a general triangle even though every experience with triangles is with specific ones? Classical cognitive science seemed to provide an answer in symbolic representation. With its easily enumerated necessary and sufficient conditions, the triangle would appear to be an ideal candidate for being represented in a symbolic form. I show that it is not. Across a variety of tasks—drawing, speeded recognition, unspeeded visual judgments, and inference—representations of triangles appear to be graded and context dependent. I show that using the category name “triangle” activates a more prototypical representation than using an arguably coextensive cue, “three-sided polygon”. For example, when asked to draw “triangles” people draw more typical triangles than when asked to draw “three-sided polygons”. Altogether, the results support the view that (even formal) concepts have a graded and flexible structure, which takes on a more prototypical and stable form when activated by category labels.  相似文献

Humans show a systematic tendency to perceive the future as psychologically closer than the past. Based on the clinical hypothesis that anxiety would be associated more with future threat life events, whereas depression with past loss events, here we explored whether people with anxiety- and depression-related personality traits perceive differently the psychological distance of temporal events. Results showed that the common tendency to perceive the future as psychologically closer than the past is exaggerated in individuals with anxiety-related personality traits, whereas this asymmetry drastically shrinks in individuals with depression-related personality traits. Beyond substantiating the hypothesis that the past and the future are differently faced by people with depression- and anxiety-related personality traits, the present findings suggest that temporal orientation of one’s self may be greatly altered in anxiety and depression.  相似文献

In recent years a number of articles have focused on the identifiability of the basic local independence model. The identifiability issue usually concerns two model parameter sets predicting an identical probability distribution on the response patterns. Both parameter sets are applied to the same knowledge structure. However, nothing is known about cases where different knowledge structures predict the same probability distribution. This situation is referred to as ʻempirical indistinguishabilityʼ between two structures and is the main subject of the present paper. Empirical indistinguishability is a stronger form of unidentifiability, which involves not only the parameters, but also the structural and combinatorial properties of the model. In particular, as far as knowledge structures are concerned, a consequence of empirical indistinguishability is that the existence of certain knowledge states cannot be empirically established. Most importantly, it is shown that model identifiability cannot guarantee that a certain knowledge structure is empirically distinguishable from others. The theoretical findings are exemplified in a number of different empirical scenarios.  相似文献

Due to mood-congruency effects, we expect the emotion perceived on a face to be biased towards one's own mood. But the findings in the scant literature on such mood effects in normal healthy populations have not consistently and adequately supported this expectation. Employing effective mood manipulation techniques that ensured that the intended mood was sustained throughout the perception task, we explored mood-congruent intensity and recognition accuracy biases in emotion perception. Using realistic face stimuli with expressive cues of happiness and sadness, we demonstrated that happy, neutral and ambiguous expressions were perceived more positively in the positive than in the negative mood. The mood-congruency effect decreased with the degree of perceived negativity in the expression. Also, males were more affected by the mood-congruency effect in intensity perception than females. We suggest that the greater salience and better processing of negative stimuli and the superior cognitive ability of females in emotion perception are responsible for these observations. We found no evidence for mood-congruency effect in the recognition accuracy of emotions and suggest with supporting evidence that past reports of this effect may be attributed to response bias driven by mood.  相似文献

We asked whether high levels of religiosity are inconsistent with a high valuation of science. We explored this possibility in three countries that diverge markedly in the relation between the state and religion. Parents in the United States (n = 126), China (n = 234) and Iran (n = 77) completed a survey about their personal and parental stance towards science. The relation between religiosity and the valuation of science varied sharply by country. In the U.S. sample, greater religiosity was associated with a lower valuation of science. A similar but weaker negative relation was found in the Chinese sample. Parents in the Iranian sample, by contrast, valued science highly, despite high levels of religiosity. Given the small size of our United States and Iranian samples, and the non-probabilistic nature of our samples in general, we caution readers not to generalise our findings beyond the current samples. Despite this caveat, these findings qualify the assumption that religiosity is inconsistent with the valuation of science and highlight the role of sociocultural context in shaping adults' perception of the relation between religion and science.  相似文献

This article is a personal testimony of the encounter between Orthodox and Anglican traditions in the 20th and the 21st centuries. It offers an overview of more than 40 years of experience in ecumenical work with Orthodox churches, beginning with an experience of Orthodoxy in Serbia in 1974 and a meeting with Fr Justin Popovi?. It continues with an account of the Fellowship of St Alban and St Sergius, which has enabled Anglicans to meet and worship with Orthodox. It concludes with a discussion of the ways in which these relationships matured after the fall of communism with the creation of the Institute for Orthodox Christian Studies in Cambridge as an example of shared theological education. The article also highlights how traditions from the East of spiritual fatherhood, the Jesus Prayer, and icons have become familiar parts of Anglican church life.  相似文献
