Communities have the potential to function effectively and adapt successfully in the aftermath of disasters. Drawing upon literatures in several disciplines, we present a theory of resilience that encompasses contemporary understandings of stress, adaptation, wellness, and resource dynamics. Community resilience is a process linking a network of adaptive capacities (resources with dynamic attributes) to adaptation after a disturbance or adversity. Community adaptation is manifest in population wellness, defined as high and non-disparate levels of mental and behavioral health, functioning, and quality of life. Community resilience emerges from four primary sets of adaptive capacities--Economic Development, Social Capital, Information and Communication, and Community Competence--that together provide a strategy for disaster readiness. To build collective resilience, communities must reduce risk and resource inequities, engage local people in mitigation, create organizational linkages, boost and protect social supports, and plan for not having a plan, which requires flexibility, decision-making skills, and trusted sources of information that function in the face of unknowns.  相似文献

Two recent studies suggest that natural scenes and paintings show similar statistical properties. But does the content or region of origin of an artwork affect its statistical properties? We addressed this question by having judges place paintings from a large, diverse collection of paintings into one of three subject-matter categories using a forced-choice paradigm. Basic statistics for images whose caterogization was agreed by all judges showed no significant differences between those judged to be 'landscape' and 'portrait/still-life', but these two classes differed from paintings judged to be 'abstract'. All categories showed basic spatial statistical regularities similar to those typical of natural scenes. A test of the full painting collection (140 images) with respect to the works' place of origin (provenance) showed significant differences between Eastern works and Western ones, differences which we find are likely related to the materials and the choice of background color. Although artists deviate slightly from reproducing natural statistics in abstract art (compared to representational art), the great majority of human art likely shares basic statistical limitations. We argue that statistical regularities in art are rooted in the need to make art visible to the eye, not in the inherent aesthetic value of natural-scene statistics, and we suggest that variability in spatial statistics may be generally imposed by manufacture.  相似文献

The inner experience of spiritual and religious feelings is an integral part of the everyday lives of many individuals. For over 100 years the role of religion as a deterrent to suicidal behavior has been studied in various disciplines. We attempt to systematize the existing literature investigating the relationship between religion/spirituality and suicide in this paper. After an overview of the attitudes of the dominant religions (e.g., Catholicism, Islam, and Buddhism) toward suicide, the three main theories that have speculated regarding the link between religion and suicide are presented: "integration theory" (Durkheim, 1897/1997), "religious commitment theory" (Stack, 1983a; Stark, 1983), and "network theory" (Pescosolido & Georgianna, 1989). Subsequent to this theoretical introduction, we report on studies on religion/spirituality keeping the suicidal path as a reference: from suicidal ideation to nonlethal suicidal behavior to lethal suicidal behavior. Studies presenting indications of religious beliefs as a possible risk factor for suicidal behavior are also presented. The last section reviews possible intervention strategies for suicidal patients and suicide survivors. Indications for future research, such as more studies on nonreligious forms of spirituality and the use of qualitative methodology to achieve a better and deeper understanding of the spiritual dimension of suicidal behavior and treatment, are offered.  相似文献

Manuel DeLanda is one of the few admitted realists in present-day continental philosophy, a position he claims to draw from Deleuze. DeLanda conceives of the world as made up of countless layers of assemblages, irreducible to their parts and never dissolved into larger organic wholes. This article supports DeLanda’s position as a refreshing new model for continental thought. It also criticizes his movement away from singular individuals toward disembodied attractors and topological structures lying outside all specific beings. While endorsing DeLanda’s realism, I reject his shift from the actual to the virtual.

Several studies have demonstrated that dynamic visual noise (DVN) does not interfere with memory for random matrices. This has led to suggestions that (a) visual working memory is distinct from imagery, and (b) visual working memory is not a gateway between sensory input and long-term storage. A comparison of the interference effects of DVN with memory for matrices and colored textures shows that DVN can interfere with visual working memory, probably at a level of visual detail not easily supported by long-term memory structures or the recoding of the visual pattern elements. The results support a gateway model of visuospatial working memory and raise questions about the most appropriate ways to measure and model the different levels of representation of information that can be held in visual working memory.  相似文献

Recent behavioral and computational research on eye movement control during scene viewing has focused on where the eyes move. However, fixations also differ in their durations, and when the eyes move may be another important indicator of perceptual and cognitive activity. Here we used a scene onset delay paradigm to investigate the degree to which individual fixation durations are under direct moment-to-moment control of the viewer’s current visual scene. During saccades just prior to critical fixations, the scene was removed from view so that when the eyes landed, no scene was present. Following a manipulated delay period, the scene was restored to view. We found that one population of fixations was under the direct control of the current scene, increasing in duration as delay increased. A second population of fixations was relatively constant across delay. The pattern of data did not change whether delay duration was random or blocked, suggesting that the effects were not under the strategic control of the viewer. The results support a mixed control model in which the durations of some fixations proceed regardless of scene presence, whereas others are under the direct moment-to-moment control of ongoing scene analysis.  相似文献

It is well established that emotions modulate memory, typically enhancing consolidation through post-learning arousal. However, many aspects of this phenomenon have yet to be delineated. For example, it remains unclear whether or not the type of arousal is relevant (pleasant vs. aversive), whether arousal enhances memory selectively for some stimuli but not others (emotional vs. neutral), which specific aspects of the stimulus representation (gist vs. detail) are affected, and whether these mechanisms are sexually dimorphic. In order to explore these issues, 178 undergraduate participants viewed a series of negative, positive and neutral pictures. They were then subjected to a post-learning arousal manipulation in the form of a pleasantly arousing-, aversively arousing-, or neutral video. Free recall tests one week later indicated that both pleasant and aversive post-learning arousal enhanced memory consolidation for positive and negative but not neutral stimuli, independent of the participants' sex. Further analysis for gist and detail aspects suggests that post-learning arousal enhances memory for the gist of the stimuli. The study has implications for the understanding of healthy and pathological cognitive-affective processes in humans.  相似文献

Self-report surveys and behavioral tasks indicate greater risk-taking behavior in adolescents as compared with adults. However, the underlying causes of these behavioral differences remain unclear. The present study examined the possibility that adolescents may be more susceptible to immediate positive and negative outcomes than adults. We compared the behavior of adolescents and adults on a modified version of the Balloon Analogue Risk Task (Lejuez et al., 2002). The task required that participants press a button to "inflate" a series of balloons on a computer screen. Balloons inflated until either the participant released the button ("saved" balloons) or the balloon "burst." Accumulated points increased as the duration of the buttonpress increased; however, simultaneously, the likelihood that the balloon would burst also increased. Adolescents inflated balloons to a larger size prior to saving them than adults did, suggesting relatively higher levels of risk taking, although the adolescents' behavior was not uniformly risk prone. Further, in comparison with adults, behavior in adolescents was more influenced by whether a balloon was saved or had burst on the preceding trial, suggesting that sensitivity to immediate consequences is one mechanism that underlies the observed difference in risk taking.  相似文献

Relapse rates for children and adolescents with major depressive disorder (MDD) range from 30% to 40% within 1 to 2 years after acute treatment. Although relapse rates are high, there have been relatively few studies on the prevention of relapse in youth. While acute phase pharmacotherapy has been shown to reduce symptoms rapidly in depressed youth, children and adolescents frequently report ongoing residual symptoms and often relapse following acute treatment. Recent adult trials have begun examining augmentation with psychosocial treatment after successful medication treatment to enhance medication response and prevent future relapse. This strategy has not yet been examined in youth with depression. Here we present initial efforts to develop a sequential, combination treatment strategy to promote rapid remission and to prevent relapse in depressed youth. We describe efforts to adapt CBT to prevent relapse (RP-CBT) in youth who respond to pharmacotherapy. The goals of RP-CBT include: preventing relapse, increasing wellness, and developing skills to promote and sustain well-being. We describe the rationale for, components of, and methods used to develop RP-CBT. The results from a small open series sample demonstrate feasibility and indicate that youth appear to tolerate RP-CBT well. A future test of the treatment in a randomized controlled trial is described.  相似文献

Developmental cognitive neuroscience is a rapidly growing field that examines the relationships between biological development and cognitive ability. In the past decade, there has been ongoing refinement of concepts and methodology related to the study of ‘functional connectivity’ among distributed brain regions believed to underlie cognition and behavioral control. Due to the recent availability of relatively easy-to-use tools for functional connectivity analysis, there has been a sharp upsurge of studies that seek to characterize normal and psychopathologically abnormal brain functional integration. However, relatively few studies have applied functional and effective connectivity analysis techniques to developmental cognitive neuroscience. Functional and effective connectivity analysis methods are ideally suited to advance our understanding of the neural substrates of cognitive development, particularly in understanding how and why changes in the functional ‘wiring’ of neural networks promotes optimal cognitive control throughout development. The purpose of this review is to summarize the central concepts, methods, and findings of functional integration neuroimaging research to discuss key questions in the field of developmental cognitive neuroscience. These ideas will be presented within a context that merges relevant concepts and proposals from different developmental theorists. The review will outline a few general predictions about likely relationships between typical ‘executive’ cognitive maturation and changes in brain network functional integration during adolescence. Although not exhaustive, this conceptual review also will showcase some of recent findings that have emerged to support these predictions.  相似文献
