基于Java的Web开发技术浅析     

吴闻 《科技广场》2013,(5):44-48

随着Web技术的广泛应用,Web开发也成为了当前软件开发的热点。Java作为面向网络的语言,与Web开发有先天的适应性,基于Java的Web开发占据了Web开发领域的较大份额。MVC模式的提出是为了适应越来越复杂的项目开发,JSP+JavaBean+Servlet可以很好实现该模式。Struts是MVC的一个经典应用,它可以大大的提高Web开发效率,且得到了越来越广泛的使用。具体开发中,应该根据需要选择合适的开发技术。  相似文献

“V+上/下”结构中对称、不对称及其对动词的选择性考察     

张芳 《河北北方学院学报(社会科学版)》2012,(3):30-33

"V+上/下"结构是现代汉语动趋式中很有特色的一对。运用描写和归纳法分析了"V+上"与"V+下"表现出的对称和不对称的情况。发现了绝对、相对两种对称情况并作出扩展性考察,基于"上/下"的词汇意义和语法意义的区别归纳出6种不对称情况,进而从语音、语法意义、语义等角度出发,考察了该结构中"上/下"搭配动词的限制性特征,具体归纳出音节重音位置的前后、音节数的多少,意义的实在与虚化、动词性质的不同等方面是其制约因素。  相似文献

Whiplash shaking syndrome: retinal hemorrhages and computerized axial tomography of the brain     

J E Carter  A Q McCormick 《Child abuse & neglect》1983,7(3):279-286

Three cases of whiplash shaking injury of infants are presented. All children presented with seizures and had minimal signs of external injury. Examination of the retina revealed extensive retinal hemorrhages. These were missed on initial examination and were only discovered after pupillary dilatation. The presence of these palecentered retinal hemorrhages suggested the diagnosis of child abuse and skeletal surveys and thorough social histories confirmed the diagnosis. Despite extensive retinal hemorrhages, computerized axial tomography (C.T.) scan showed minimal inter-hemispheric bleeding. In contrast to the "Battered Child Syndrome," all the findings in whiplash shaking syndrome of infants are subtle and demand an awareness, an index of suspicion and a thorough examination which may include extensive retinal examination following dilatation of the pupils. This latter examination is frequently not performed by family physicians and residents so that the syndrome may be missed. A fourth case is also discussed where shaking is admitted on initial presentation but said to be done for resuscitation. This poses an immense diagnostic dilemma to the pediatrician since in this case the child presented later with all the signs of physical abuse.  相似文献   

Factor structure of the WISC‐V in four standardization age groups: Exploratory and hierarchical factor analyses with the 16 primary and secondary subtests          下载免费PDF全文

Gary L. Canivez  Stefan C. Dombrowski  Marley W. Watkins 《Psychology in the schools》2018,55(7):741-769

This study examined the factor structure of the Wechsler Intelligence Scale for Children‐Fifth Edition (WISC‐V) with four standardization sample age groups (6–8, 9–11, 12–14, 15–16 years) using exploratory factor analysis (EFA), multiple factor extraction criteria, and hierarchical EFA not included in the WISC‐V Technical and Interpretation Manual. Factor extraction criteria suggested that one to four factors might be sufficient despite the publisher‐promoted, five‐factor solution. Forced extraction of five factors resulted in only one WISC‐V subtest obtaining a salient pattern coefficient on the fifth factor in all four groups, rendering it inadequate. Evidence did not support the publisher's desire to split Perceptual Reasoning into separate Visual Spatial and Fluid Reasoning dimensions. Results indicated that most WISC‐V subtests were properly associated with the four theoretically oriented first‐order factors resembling the WISC‐IV, the g factor accounted for large portions of total and common variance, and the four first‐order group factors accounted for small portions of total and common variance. Results were consistent with EFA of the WISC‐V total standardization sample.  相似文献   

河北孟村方言“活Adj/V死”结构及其演化     

董淑慧 《沧州师专学报》2013,29(3):11-13,42

河北孟村方言中的“活Adj/V死”结构表示“程度达到极致”,进入该结构的多为性质形容词、心理动词和少量动宾结构.从历时角度考察,该结构经历了从“生生/活活V”到“生生/活活V死”,再到“生生/活活Adj/V死”的形式转变,其中“活”和“死”也逐步虚化为程度副词,以“活Adj/V死”结构保存在少数方言中.  相似文献
