This paper is a study of the image of the Jews in Islamist discourse in modern Egypt. The rise of Zionism and the founding of the state of Israel created a confluence of political and religious interests whereby the Qur'anic view of the Jews was wedded with European anti‐Semitic ideas to create a trans‐historical symbol of evil. Islamist groups used the resulting image of the Jews as a vehicle of Islamic reform. The radicalization of some Islamists, however, changed the way that image functioned in Islamist discourse, making it more central to understanding both the crisis of modern Islam and Egyptian identity. 相似文献

This article draws upon recent findings from the field of neuroscience to explore how loss aversion affects foreign policy resolve. We theorize that U.S. policy makers are more resolute in pursuing preventive policies that seek to avoid losses than they are in pursuing promotive policies that seek to acquire new gains. To test our theory, we conduct the first large‐n analysis of foreign policy hypotheses derived from the neuroscience of loss aversion using data from 100 cases of U.S.‐initiated Section 301 trade disputes. The results provide strong support for the loss‐aversion‐based theory, revealing that American policy makers are willing to fight harder and hold out longer in trade disputes with preventive objectives than they are in cases with promotive ones. Our study demonstrates that hypotheses derived from neuroscientific findings can be tested using large‐n techniques in study of foreign policy, revealing a new avenue of inquiry within the field. 相似文献

Contamination aversion is implicated in a range of psychological disorders, such as obsessive-compulsive disorder and health anxiety. Despite broad implications, the core mechanisms mediating contamination aversion are mixed and have not clearly been elucidated. The present studies are psychometric investigations of the components of contamination aversion and tests of the different mechanisms that mediate the severity of these components. In Study 1, items from existing measures of contamination aversion were compiled into one measure and administered to a large sample of nonclinical participants (N?=?1,286). Exploratory factor analyses demonstrated a two-factor structure, with one factor comprised of items related to intrinsically (direct) contaminated objects and the other factor comprised of items related to extrinsically (indirect) contaminated objects. In Study 2, items were added and confirmatory factor analyses supported a two-factor model in another large nonclinical sample (N?=?612). In Study 3 (N?=?471), structural modeling demonstrated distinct relations between the two factors and affective and cognitive constructs. Affective constructs related more to aversions toward more directly contaminated objects and situations while cognitive constructs related more to aversions toward more indirectly contaminated objects and situations. The present studies help clarify and articulate the unique roles of cognition and affect in specific contamination aversions, and, as such, have important implications for conceptual modeling of contamination-related psychopathology. 相似文献

Sales research to date has focused on coping styles as measured by problem-focused coping (PFC) and emotion-focused coping (EFC), but it has excluded time management perceptions and behaviors as ways of coping with stress (Srivastava and Sager 1999; Strutton and Lumpkin 1993). This study examines a coping model that integrates EFC, PFC, and time management behaviors in the rubric of a profile. The profile allows for practice of several coping behaviors simultaneously. Using data gained from salespeople, four tentative coping strategy profiles are developed and examined relative to personal characteristics and job outcomes. Study results suggest that salespeople who are able to better handle stress use time management behaviors more often in addition to using high levels of PFC and low levels of EFC. 相似文献

Abstract Increasing evidence suggests that regular physical activity can have considerable psychological, as well as physical, benefits in the elderly. Although factors such as exercise dosage may be implicated in exercise-induced affect responses, it has also been suggested that social and psychological factors might influence this relationship. This study examined the roles played by exercise environment (group versus alone) and self-efficacy in affective change in 80 older adults (M age = 66 yrs) over the course of three acute exercise bouts. Using latent growth curve methodology and statistically controlling for duration and intensity of exercise, we were able to demonstrate that social (group) environments resulted in statistically significant improvements in feeling state responses when contrasted with a condition in which the participants exercised alone. In addition, increases in self-efficacy were associated with more positive and less negative feeling states. Environmental factors that might influence the exercise-affect response are discussed and recommendations for subsequent exercise, efficacy, affect research made. 相似文献

We have investigated the thermoelectric material Zn4Sb3 using transmission electron microscopy (TEM). Nanoscale inclusions with a diameter of about 10 nm were observed, constituting on the order of 1% by volume of the material. Studies using energy filtered imaging, electron diffraction, and high-angle annular dark-field STEM indicate that the inclusions consist of Zn. These inclusions are expected to scatter the medium and long-wavelength phonons effectively, thus contributing to phonon glass behavior which results in the exceptionally low thermal conductivity for this thermoelectric material. 相似文献

Learning names for parts of objects can be challenging for children, as it requires overcoming their tendency to name whole objects. We test whether comparing items can facilitate learning names for their parts. Applying the structure-mapping theory of comparison leads to two predictions: (a) young children will find it easier to identify a common part between two very similar items than between two dissimilar items (because the similar pair is easier to align); (b) close alignments potentiate far alignments: children will be better able to extend a novel part name to a dissimilar object after having extended it to a similar object. In three studies, 227 preschool children mapped novel part terms to new animals or objects. Both predictions were confirmed. Children more accurately extended novel part terms to objects that were similar to the standard than to objects that were dissimilar (Experiments 1 and 2), and children more accurately extended novel part names to dissimilar objects after having extended them to similar objects (Experiment 3). We conclude that structure-mapping processes can support part learning. 相似文献

Abstract Sport scientists have started to amass a small body of knowledge on loss in sport. Viewing sport retirement from a loss framework is particularly appropriate when examining transitions out of disability sport because athletes with disabilities are at risk for facing unique losses when they lease sport (Martin, 1996; Wheeler, Malone, & Steadward, 1996). The purpose of this article is to discuss loss experiences in disability sport from psychological, social, and physiological perspectives. 相似文献

This study explored the effects of bullying victimization (BV), as a Type II traumatic stressor, on intelligence quotient (IQ), posttraumatic stress disorder (PTSD), and complex PTSD symptoms. Participants were 390 African American and Iraqi refugee adolescents. Measures of BV, cumulative life trauma, PTSD, discrimination, and IQ were administered. Correlational, multilevel regression, and path analyses were conducted. BV, independent of cumulative trauma, and discrimination were found to have significant direct effects on increased PTSD symptoms and significant direct and indirect negative effects on perceptual reasoning, processing speed, and working memory. BV was also associated with increases in the discrepancy between perceptual reasoning and verbal comprehension. The implications of these results for the prevention and treatment of bullying victims are discussed. 相似文献
