摘要： The definition, characteristics, research category and research value of law-deviant activities of university students were studied. It is proposed that the study on the law-deviant activities of university students is greatly significant to administer the illegal activities of university students and improve the educational management mechanism.

关键词： breast cancer   cen17   FISH   Her2   polysomy  

摘要： Aims: HER2 testing of invasive breast cancer by in-situ hybridization guides therapy decisions. Probing HER2 and centromere of chromosome 17 (cen17) simultaneously is supposed to reveal both a potential HER2 gene amplification and polysomy 17. However, a considerable number of breast cancer patients with quasi polysomy 17 are considered 'equivocal', which is diagnostically meaningless. Moreover, patients with equivocal/false polysomic tumours are prevented from a potentially beneficial anti-HER2 treatment. Here we evaluated the RAI1, D17S122 and TP53 hybridization markers to indicate true polysomy reliably and to reclassify equivocal samples accurately as HER2-positive. Methods and results: Samples with (n = 82) and without (n = 52) increased cen17 copy numbers and 78 evidently HER2-amplified specimens were analysed using dual and triple marker hybridization probes. Selected putative polysomic samples were subjected to array-based comparative genomic hybridization (aCGH). We found that 37.8% samples with putative polysomy 17 did not show any gain in RAI1, D17S122 or TP53. Accordingly, aCGH revealed evidence for the presence of HER2/cen17 co-amplification rather than for true polysomy in those cases. Reflex testing using alternate 17p markers reclassified up to 56.3% equivocal cases as HER2-positive and the combined assessment of a 17p and 17q locus allows the differentiation of true versus false polysomy. Conclusions: An increased cen17 copy number does not necessarily reflect polysomy, and reflex testing facilitates the reclassification of 'equivocals'. Nevertheless, the prognostic and predictive value of a HER2/cen17 co-amplification versus HER2 gene amplification alone must still be evaluated prospectively.

关键词： Tax behavior   Age   Sex   Education   Income   Meta-analysis  

摘要： Tax compliance varies across sociodemographic categories. However, research on the relationships between compliance and age, sex, education as well as income level shows inconsistent results, both regarding the direction of the relationship and its size. The current meta-analyses target to merge findings in survey studies on age, sex, education, and income and estimate the strength of the impact on compliance by taking into account geographical regions. In four meta-analyses, comprising 459 samples (N = 614,286) from 111 countries published between 1958 and 2012, average estimated effect sizes were small, ranging from r = 0.12 for the relationship between compliance and age, r = 0.06 for sex, r = 0.02 for education to r = 0.04 for income. These effects are more pronounced in Western countries. It thus appears sociodemographic characteristics have little impact on compliance, but nevertheless should be controlled for in tax research.

关键词： Object recognition   Nonlinear features   Semantic category   EEG signals  

摘要： The problem of object recognition is solved in the brain using different strategies. These strategies are to some extent known to neuroscientists, but researches on this issue are still in progress to understand more accurately the computational, anatomical, and physiological aspects of this fast and accurate capability of the brain. In this paper, we presented a method, based on extracting nonlinearity of signals such as L-Z complexity, fractal dimension, Lyapunov exponents, Hurst exponents, and entropy, to classify single trials into their related semantic category groups with a linear SVM classifier. Furthermore, we proposed to combine nonlinear features mentioned above with wavelet coefficients to improve the classification accuracy. EEG signals were recorded from human subjects according to 10-20 system while performing a "go/no go" object-categorization task. Combining nonlinear features with wavelet coefficients led to a significant enhancement in classification accuracy (73%) relative to wavelet coefficients alone (54%). Feature-selection results showed that a significantly larger proportion of final selected features include nonlinear features (44%) relative to the first ratio of them (14%) to whole features. This ratio enhancement demonstrates the essential role of nonlinear features in the obtained classification accuracy. In addition, C3 channel and Katz fractal dimension were introduced as the most informative channel and the best nonlinear feature, respectively.

摘要： 1941年冬至1943年春,王子云率西北艺术文物考察团进入敦煌石窟,"敦煌热"催生了大批学者艺术家进入西北。"西北"从而从一个地理概念转化成文化概念。油画进入西北地区的路线大约有早期俄国画家在新疆的活动以及内陆画家在西北的油画实践两个方向。从发展阶段来看,可以概括为抗战时期以及中华人民共和国成立后、"文化大革命"时期、20世纪80年代乡土美术时期和当代西部题材绘画,革命史和美术史的双重身份给予西北绘画特殊内涵,独特的地域文化样貌给了西北地区迥异的外在,民族符号特征带来了鲜明形象,也带来了在当代语境中叙事的固化。

摘要： 一 就当下而言，对各种风格与趣味的书法品鉴首先要在类型与范畴两个层面加以区分。二者不可混同，范畴具有观念性，类型则是实在的。例如，“丑”，张法将之划分在“喜”的类型之中，“喜”的可笑不同于美的愉悦.

关键词： “淡”范畴   茶道精神   道家   哲学  

摘要： 我国古代文论"淡"范畴的发展不仅催生了崇尚淡泊之性、平淡之美的文学形式,而且还与我国传统茶道精神形成了天然的契合。本文通过对中国古代文论"淡"范畴与茶道"和"、"静"、"真"等精神的联系,探讨茶道文化及古代文论的道家精神,从而探究我国传统茶道精神和古代文论的艺术魅力和价值。

关键词： 美学范畴   戏曲美学   戏曲作品   中国化   悲剧性   喜剧性   音乐作品   民族文化  

摘要： 悲剧、喜剧的概念在中国古代剧论中没有，是从西方引进的，但现在已为大家广泛使用，已成为中国戏曲美学的一对重要范畴，这说明这对范畴已经“中国化”了。它之所以能够中国化，一是因为世界戏剧具有共同性，彼此在理论上能够互相吸收借鉴；二是因为中国古代虽然没有这一名词，但戏曲作品（以及诗歌、音乐作品）中确实存在着悲剧性、喜剧性的因素，很多戏曲作品从内容上和风格上可以有悲剧、喜剧之分。然而由于中、西民族文化的不同，中国的悲剧、喜剧与西方的悲剧、喜剧又有明显不同。

摘要： 南宋文士在用休闲范畴形容、赞美人格与艺术的同时,也将其用于对自然美的描绘,主要包括植物、动物,也包括自然景观等。究其实质,它仍是传统美学中"比德"观念的一种形式,是南宋文士主体人格的尚闲之思与休闲之美在自然物上的投射与移情。
