The theme of this essay is expressed in a line from the Dao De Jing: "The great image has no form." The essay shows how this effacement, annulment, or withdrawal of form is realized in ancient Chinese painting (Song and Ming Dynasties) and in the conception of the natural elements to which much of this painting is related. Certain resonances with this effacement of form are identified in the way that recent Continental thought focuses on an effacement of form as it was determined in ancient Greek philosophy.  相似文献

为探讨浪漫媒介内容接触对大学生浪漫信念的影响及其作用机制,采用浪漫媒介内容接触问卷、感知真实性量表、社会比较倾向量表和浪漫信念量表对614名无恋爱经验的大学生进行调查,结果发现:(1)浪漫媒介内容接触与感知真实性和浪漫信念都呈显著正相关,感知真实性和浪漫信念也呈显著正相关;(2)感知真实性在浪漫媒介内容接触对浪漫信念的影响中起中介作用;(3)浪漫媒介内容接触对浪漫信念影响的直接效应,以及感知真实性的中介效应均受到社会比较倾向的调节,且在高社会比较倾向群体中,这两种效应都更显著。  相似文献

The present research investigates perceived fit effects according to the focus that consumers place when evaluating brand extensions. Process‐focus encourages consumers to focus their thoughts on the process of reaching an outcome, thereby affecting extension evaluations on the basis of the process similarity between the original brand and its extensions. Conversely, outcome‐focus encourages consumers to focus their thoughts on the final outcome, thereby affecting extension evaluations on the basis of the final outcome similarity between the original brand and its extensions. With this conceptual framework, the present research demonstrated that for the process‐focus condition, the extension was evaluated more favorably when the similarity between the process of the original brand and the process of its extension was present (Study 1). By contrast, for the outcome‐focus condition, the extension was evaluated more favorably when the similarity between the final outcome of the original brand and the final outcome of its extension was present (Study 2).  相似文献

Forensic evidence often involves an evaluation of whether two impressions were made by the same source, such as whether a fingerprint from a crime scene has detail in agreement with an impression taken from a suspect. Human experts currently outperform computer‐based comparison systems, but the strength of the evidence exemplified by the observed detail in agreement must be evaluated against the possibility that some other individual may have created the crime scene impression. Therefore, the strongest evidence comes from features in agreement that are also not shared with other impressions from other individuals. We characterize the nature of human expertise by applying two extant metrics to the images used in a fingerprint recognition task and use eye gaze data from experts to both tune and validate the models. The Attention via Information Maximization (AIM) model (Bruce & Tsotsos, 2009) quantifies the rarity of regions in the fingerprints to determine diagnosticity for purposes of excluding alternative sources. The CoVar model (Karklin & Lewicki, 2009) captures relationships between low‐level features, mimicking properties of the early visual system. Both models produced classification and generalization performance in the 75%–80% range when classifying where experts tend to look. A validation study using regions identified by the AIM model as diagnostic demonstrates that human experts perform better when given regions of high diagnosticity. The computational nature of the metrics may help guard against wrongful convictions, as well as provide a quantitative measure of the strength of evidence in casework.  相似文献

In this article we explore two propositions concerning the manner in which judgmental God image affects social trust among the highly religious in the United States. One proposition argues that having a judgmental God image and being highly embedded in a community of co-religionists can create low levels of social trust through social bonding and the formation of particularized trust. The other proposition maintains that embeddedness in a moral community of co-religionists helps to reinforce the idea that people are basically good and require love and forgiveness. This leads to higher levels of trust. We test an interaction between judgmental God image and social embeddedness with OLS analysis and data from the 2014 Baylor Religion Survey. We restrict the analysis to the highly religious, those who have no doubt about the existence of God and belong to a place of worship. We find that respondents with a judgmental God image who do not belong to a moral community with any or a few friends have the lowest levels of social trust. Those who have a judgmental God image but are highly embedded in a moral community with at least half of their friends have higher levels of social trust. Embeddedness negates the negative effects of judgmental God image on social trust. Implications for research are discussed in the conclusion.  相似文献

Breast cancer (BC) patients in China suffered from a variety of psychology stress such as perceived stress and anxiety, posttraumatic growth (PTG) as a positive factor could promote their psychology health and quality of life. This study aimed to investigate the efficacy of mindfulness-based stress reduction (MBSR) on promoting PTG, decreasing perceived stress and anxiety of Chinese BC patients. A randomized controlled trial of 60 BC patients (Stages I–III) was conducted. They were randomly divided to the 8-week MBSR group or usual care (UC) group. PTG inventory, Perceived Stress Scale of Chinese version (CPSS) and State Trait Anxiety Inventory (STAI) evaluated the PTG level, perceived stress and anxiety at three times(before intervention-T1, after intervention-T2 and follow up at 3 months-T3). A repeated-measures analysis of variance model was used to compare each outcome measure of two groups at the three times. There was one patient discontinued the intervention and one lose to follow up in MBSR group, finally 58 BC patients completed the research. There was no difference between two groups before the intervention. The results showed significant improvements in MBSR group comparing with the UC group that PTG level was much higher after the 8-week intervention and the follow up (F = 34.73, p < .00). At the same time, CPSS (F = 14.41, p < .00) and STAI (F = 15.24, p < .00) scores were significant decreased at T2 and T3. The results showed that MBSR promoted the level of PTG and decreased perceived stress and anxiety state of Chinese BC patients, and the results persisted at three months after intervention. The research preliminary proved that MBSR was suitable to Chinese BC patients. MBSR should be recommending to BC survivors in China.  相似文献
