随着微创技术的发展,腹腔镜阑尾切除术(1aparoscopic appendectomy,LA)正逐渐被广大医务工作者所接受,但现在仍然有很多人认为LA与传统开腹阑尾切除术(open appendectomy,OA)相比没有优势,而且LA价格昂贵,不适合推广。但是作为正在发展完善的新技术,很多证据表明LA与OA相比优势正在逐步增强。 相似文献

When a target appears in the same peripheral location as a previous cue, responding is typically delayed if the cue-target interval is relatively long. This phenomenon is termed inhibition of return (IOR) and has been suggested to reflect an attentional bias in favour of novel visual space. It has been demonstrated recently that IOR is much stronger in the far periphery than in the perifoveal visual field. The present study further investigated the neural mechanisms underlying this eccentricity effect of IOR with an event-related fMRI technique. The results demonstrated a stronger activation in visual cortex for perifoveal processing and a broader activation in multiple brain areas for peripheral processing. When IOR effects were compared between these two areas, a stronger activation of the fronto-parietal network was evidenced for perifoveal versus peripheral IOR, while the prefrontal cortex was more strongly involved in the peripheral IOR versus perifoveal IOR. These results suggest that different neural mechanisms are mediating the dissociable inhibitory functions between the perifoveal and peripheral visual field. 相似文献

Semantic processing from parafoveal words is an elusive phenomenon in alphabetic languages, but it has been demonstrated only for a restricted set of noncompound Chinese characters. Using the gaze-contingent boundary paradigm, this experiment examined whether parafoveal lexical and sublexical semantic information was extracted from compound preview characters. Results generalized parafoveal semantic processing to this representative set of Chinese characters and extended the parafoveal processing to radical (sublexical) level semantic information extraction. Implications for notions of parafoveal information extraction during Chinese reading are discussed. 相似文献

Because television has the potential to shape cultural beliefs about both sexual norms and appropriate workplace behavior,
it seems important to examine TV’s portrayal of “sexual etiquette” in the workplace. In a content analysis of two episodes
of every primetime comedy aired on all broadcast and cable networks during fall 2000, we coded every sexual remark and behavior
made in a workplace scene. Across all networks, 85 percent of programs and one in four workplace interactions contained some
type of sexual content. Overall, a viewer is likely to hear eleven sexual remarks and see two to three sexual behaviors in
a workplace setting per hour; this jumps to twenty-three remarks and nine behaviors on cable networks. Sexual remarks were
mostly explicit, made in an office setting, by White men, and were rarely (1.4%) about sexual harassment or discrimination.
Although sexual content in the workplace was generally less common on broadcast than cable networks, a broadcast network (Fox)
actually had the highest overall rate, with sexual content in 38 percent of workplace scenes. Given that research suggests
that TV teaches youth about sexuality and cultivates sexual attitudes and beliefs consistent with televised portrayals, it
is alarming that youth may learn from television that sex in the workplace is not only commonplace, but also to be tolerated
and enjoyed. 相似文献

三校大学生竞争/合作策略取向的特点及影响因素 总被引:3,自引:0,他引:3
为研究大学生竞争/合作策略取向的特点及影响因素,采用”合作与竞争策略标度”量表对144名大学生进行测查,并从能力变量、期望变量及背景变量进一步研究其影响因素。结果表明大学生竞争策略均分值普遍显著高于合作策略均分值,提示学生更崇尚竞争策略;女生的竞争策略均分值明显高于男生分值,表现出策略取向的性别差异。通过相关分析和多元逐步回归分析,表明学习能力、总体能力与父母期望对学生的竞争策略取向有一定的预测性,而性别和母亲受教育程度可部分预测学生合作策略取向。 相似文献
