校报受众心理及维模功能探究 总被引：1，自引：0，他引：1
李建林 《番禺职业技术学院学报》2009,8(1):39-42
要办好高校校报,就必须了解受众的心理特征和精神需求。要充分调动受众的积极心理,降低受众的消极心理,强化受众的维模心理。这样,校报才能真正成为高校思想政治工作中的主阵地,成为高校编外“政治辅导员”。 相似文献

Objective: Optimization of combining electroencephalography (EEG), short latency somatosensory evoked potentials (SLSEP) and transcranial Doppler (TCD) techniques to diagnose brain death. Methods: One hundred and eleven patients (69 males, 42 females) from the major hospitals of Zhejiang Province were examined with portable EEG, SLSEP and TCD devices. Re-examinations occurred ≤12 h later. Results: The first examination revealed that the combination of SLSEP and EEG led to more sensitive diagnoses than the c... 相似文献

Recent research in the human computer interaction and information retrieval areas has revealed that search response latency exhibits a clear impact on the user behavior in web search. Such impact is reflected both in users’ subjective perception of the usability of a search engine and in their interaction with the search engine in terms of the number of search results they engage with. However, a similar impact analysis has been missing so far in the context of sponsored search. Since the predominant business model for commercial search engines is advertising via sponsored search results (i.e., search advertisements), understanding how response latency influences the user interaction with the advertisements displayed on the search engine result pages is crucial to increase the revenue of a commercial search engine. To this end, we conduct a large-scale analysis using query logs obtained from a commercial web search. We analyze the short-term and long-term impact of search response latency on the querying and clicking behaviors of users using desktop and mobile devices to access the search engine, as well as the corresponding impact on the revenue of the search engine. This analysis demonstrates the importance of serving sponsored search results with low latency and provides insight into the ad serving policy of commercial search engines to ensure long-term user engagement and search revenue. 相似文献

赣南,中原汉人南迁的中转站与聚散地,是客家民系形成的摇篮。然而,这里的客家认同意识却不如闽粤强。基于此,本文拟从自然地理、民族交融特点和“客家热”的兴起以及客家研究宣传等方面分析赣南客家族性潜隐的深层原因。 相似文献

Several studies performed on deep orthography systems reveal variables that influence writing latencies that occur over the course of learning. In transparent orthographies such as Spanish there are very few studies on writing that measure latencies and duration. The aim of this present study was to take a more in-depth look at knowledge of the writing mechanisms used by Spanish children in primary education, by studying the errors, latencies and duration of the writing of words. To do this, sixty children performed a copying task and a dictation task with regular words of different frequency and length. The obtained results show changes in the writing mechanisms used by the children as they became more expert, as indicated by the greater effect of word length in the first years of primary. This word length effect is a more determining factor with regard to the number of letters in words than for the number of syllables. These results hold important implications for the teaching of writing in Spanish. 相似文献

Tai Chi Chuan is a favourite form of exercise throughout the world and has drawn increasing research interest from international scientists. Biomechanical research into Tai Chi has grown substantially and has provided evidence of the beneficial effects of Tai Chi exercise on health, fitness, and prevention of falls. This paper reviews studies that have explored the biomechanical aspects of Tai Chi, such as balance, kinematics, kinetics, strength, and neuromuscular activities. 相似文献

This study aimed to investigate the activation of lower limb muscles during barefoot and shod running with forefoot or rearfoot footfall patterns. Nine habitually shod runners were asked to run straight for 20 m at self-selected speed. Ground reaction forces and thigh and shank muscle surface electromyographic (EMG) were recorded. EMG outcomes (EMG intensity [iEMG], latency between muscle activation and ground reaction force, latency between muscle pairs and co-activation index between muscle pairs) were compared across condition (shod and barefoot), running cycle epochs (pre-strike, strike, propulsion) and footfall (rearfoot and forefoot) by ANOVA. Condition affected iEMG at pre-strike epoch. Forefoot and rearfoot strike patterns induced different EMG activation time patterns affecting co-activation index for pairs of thigh and shank muscles. All these timing changes suggest that wearing shoes or not is less important for muscle activation than the way runners strike the foot on the ground. In conclusion, the guidance for changing external forces applied on lower limbs should be pointed to the question of rearfoot or forefoot footfall patterns. 相似文献

突聋听性脑干诱发电位分析 总被引：2，自引：0，他引：2
为探讨突发性耳聋患者听性脑干诱发电位（ＡＢＲ）的特征,对４２例突发性耳聋患者的ＡＢＲ资料作回顾性分析。本组突聋患者ＡＢＲ测试均出现异常,波１潜伏期较对照组明显延长（Ｐ〈０．００１）;波Ｉ～Ⅲ、Ｉ～Ⅴ间期较对照组明显缩短（Ｐ〈０．０５）;眩晕组较无眩晕组较无眩晕组波Ｉ潜伏期明显延长（Ｐ〈０．０５）本组资料提示突聋患者ＡＢＲ以波１潜伏期延长为特征,伴有眩晕的突聋患者较无眩晕者病变程度重,波１潜伏期更长 相似文献
