This paper presents research findings from fieldwork in the rap scene of Tunis. Although the scene is relatively small, especially
when compared to its Algerian counterpart, the number of young men involved in rap is expanding rapidly, particularly with
the internet as a networking and promoting tool. Throughout the discussion I explore some of the ways that (Sunni) Islam intersects
with rap in the artists’ lives, lyrics and identities, and the ways that their particular locatedness informs their position
within what has been termed the ‘transglobal hip hop nation’. Whilst interpreting religion has long been a contested area
in Tunisia, it seems that rap here functions as a route to articulating alternative interpretations of Islam, ones which not
only unite the artists but offer potential for pan-umma and transglobal connectivities. These potentialities resonate with
the idea of a ‘transglobal hip hop ummah’ and provide the artists with arenas for personal, political, collective and spiritual
expression. 相似文献

Factors predicting the use of technology: findings from the Center for Research and Education on Aging and Technology Enhancement (CREATE) 总被引:4,自引:0,他引:4

The successful adoption of technology is becoming increasingly important to functional independence. The present article reports findings from the Center for Research and Education on Aging and Technology Enhancement (CREATE) on the use of technology among community-dwelling adults. The sample included 1,204 individuals ranging in age from 18-91 years. All participants completed a battery that included measures of demographic characteristics, self-rated health, experience with technology, attitudes toward computers, and component cognitive abilities. Findings indicate that the older adults were less likely than younger adults to use technology in general, computers, and the World Wide Web. The results also indicate that computer anxiety, fluid intelligence, and crystallized intelligence were important predictors of the use of technology. The relationship between age and adoption of technology was mediated by cognitive abilities, computer self-efficacy, and computer anxiety. These findings are discussed in terms of training strategies to promote technology adoption. 相似文献

This paper investigates the ability of infants to attend to continuous stimulus variables and how this capacity relates to the representation of number. We examined the change in area needed by 6-month-old infants to detect a difference in the size of a single element (Elmo face). Infants successfully discriminated a 1:4, 1:3 and 1:2 change in the area of the Elmo face but failed to discriminate a 2:3 change. In addition, the novelty preference was linearly related to the ratio difference between the novel and familiar area. Results suggest that Weber's Law holds for area discriminations in infancy and also reveal that at 6 months of age infants are equally sensitive to number, time and area. 相似文献

Successes--defined broadly as meeting important standards or receiving positive evaluations--are widely assumed to be enjoyed equally by people with high self-esteem (HSEs) and low self-esteem (LSEs). Three studies examined the contradictory hypothesis that HSEs react more favorably to success than do LSEs and that success brings about certain unfavorable consequences for LSEs. Undergraduate participants reacted to a laboratory-manipulated success (Studies 1 and 2) or imagined highly positive events in the future (Study 3). Self-esteem differences emerged in anxiety, thoughts about the self, and (in Study 3) thoughts about non-self-related aspects of the event. LSEs were more anxious than HSEs after succeeding, success improved HSEs' self-relevant thoughts but not LSEs', and LSEs focused more on success's negative aspects. 相似文献

The relative importance of an internal sense of direction based on inertial cues and landmark piloting for small-scale navigation by White King pigeons (Columba livia) was investigated in an arena search task. Two groups of pigeons differed in whether they had access to visual cues outside the arena. In Experiment 1, pigeons were given experience with 2 different entrances and all pigeons transferred accurate searching to novel entrances. Explicit disorientation before entering did not affect accuracy. In Experiments 2-4, landmarks and inertial cues were put in conflict or tested 1 at a time. Pigeons tended to follow the landmarks in a conflict situation but could use an internal sense of direction to search when landmarks were unavailable. 相似文献

We investigate the hypothesis that those subregions of the prefrontal cortex (PFC) found to support proactive interference
resolution may also support delay-spanning distractor interference resolution. Ten subjects performed delayed-recognition
tasks requiring working memory for faces or shoes during functional MRI scanning. During the 15-sec delay interval, task-irrelevant
distractors were presented. These distractors were either all faces or all shoes and were thus either congruent or incongruent
with the domain of items in the working memory task. Delayed-recognition performance was slower and less accurate during congruent
than during incongruent trials. Our fMRI analyses revealed significant delay interval activity for face and shoe working memory
tasks within both dorsal and ventral PFC. However, only ventral PFC activity was modulated by distractor category, with greater
activity for congruent than for incongruent trials. Importantly, this congruency effect was only present for correct trials.
In addition to PFC, activity within the fusiform face area was investigated. During face distraction, activity was greater
for face relative to shoe working memory. As in ventrolateral PFC, this congruency effect was only present for correct trials.
These results suggest that the ventrolateral PFC and fusiform face area may work together to support delay-spanning interference
resolution. 相似文献

This study examined longitudinal relations among adolescents' family relationships, peer relationships, and problem behavior. Participants were 1,357 African American and European American adolescents who were interviewed at 3 time points: 7th grade (mean age = 12.7 years), the summer after 8th grade (mean age = 14.2 years), and 11th grade (mean age = 17.1 years). For all racial and gender groups, 7th-grade family characteristics (youth perceptions of autonomy and warmth) predicted a risky peer context during 8th grade, which in turn predicted problem behavior during 11th grade. Additionally, problem behavior in the 7th grade predicted 11th-grade problem behavior, directly as well as indirectly through the peer context. Racial and gender differences are discussed, as are implications for future research. 相似文献
