Depravity of Lianne in Falling Man

Falling Man is different from DeLillo’s other previous works, and this work focuses on the psychological strike of general public caused by the terrorist attack. DeLillo uses spatial transformations to focus on narrating the 9/11 incident by separation and reunion of an ordinary American family. While this paper focuses on the life outlook depravity with the transformation of living space.

Using iPad tablets for self‐modeling with preschoolers: Videos versus photos

As technology becomes more accessible and acceptable in the preschool setting, teachers need effective strategies of incorporating it to address challenging behaviors. A nonconcurrent delayed multiple baseline design in combination with an alternating treatment design was utilized to investigate the effects of using iPad tablets to display video self‐modeling and activity photos for three preschoolers during circle time. During baseline, all three children demonstrated low levels of engagement and high levels of off‐task behavior compared to peers. The intervention phase consisted of alternating between showing the child the self‐video and photos prior to circle time. A child preference phase was conducted whereby each child self‐selected the video or photo prior to circle time. For all three children both videos and photos led to increased engagement and decreased off‐task behaviors. During the child preference phase, all three children selected the video most frequently. Social validity data demonstrated teacher and child preference for the video self‐modeling condition.     

Comparing rankings of search results on the Web

The Web has become an information source for professional data gathering. Because of the vast amounts of information on almost all topics, one cannot systematically go over the whole set of results, and therefore must rely on the ordering of the results by the search engine. It is well known that search engines on the Web have low overlap in terms of coverage. In this study we measure how similar are the rankings of search engines on the overlapping results.We compare rankings of results for identical queries retrieved from several search engines. The method is based only on the set of URLs that appear in the answer sets of the engines being compared. For comparing the similarity of rankings of two search engines, the Spearman correlation coefficient is computed. When comparing more than two sets Kendall’s W is used. These are well-known measures and the statistical significance of the results can be computed. The methods are demonstrated on a set of 15 queries that were submitted to four large Web search engines. The findings indicate that the large public search engines on the Web employ considerably different ranking algorithms.     

Profiles of emergent literacy skills among preschool children who are at risk for academic difficulties

The purpose of this study was to explore patterns of within-group variability in the emergent literacy skills of preschoolers who are at risk for academic difficulties. We used the person-centered approach of cluster analysis to identify profiles of emergent literacy skills, taking into account both oral language and code-related skills. Participants were 492 preschoolers (aged 42-60 months) enrolled in needs-based programs. In the fall of the academic year, children were administered eight measures of emergent literacy: four oral language measures (i.e., expressive and receptive grammar, expressive and receptive vocabulary) and four code-related measures (i.e., print concepts, alphabet knowledge, name writing, and rhyme). Controlling for age, hierarchical-agglomerative and K-means cluster analysis procedures were employed. Five psychometrically sound profiles emerged: highest emergent literacy (prevalence = 14%); three profiles with average oral language and differential code-related abilities (16%, 24%; 23%); and lowest oral language with broad code-related weaknesses (23%). Profiles were then compared on midyear teacher ratings of emergent literacy as well as end-of-kindergarten literacy performance; results provided convergent evidence of predictive validity. This study highlights the considerable heterogeneity of emergent literacy abilities within an “at-risk” group. The resulting profiles have theoretical and practical relevance when examining both concurrent relationships between oral language and code-related skills as well as longitudinal relationships between early patterns of performance and later reading achievement.

安徽省城市土地利用效率与经济发展水平的耦合效应

采用数据包络分析方法（DEA）测算2000-2011年安徽省17个地市（包括原巢湖市）土地利用效率,按其土地利用效率水平将这些城市分为高度有效型、中度有效型、较为有效型和低度有效型四种类型.依据耦合度理论,构建城市土地利用效率与经济发展水平的耦合协调度模型,结果显示：安徽省各城市土地利用效率与经济发展水平普遍处于高耦合、低协调状态.利用灰色关联度分析法可知,造成这种状况的主要因素是城市规划建设与经济发展水平不同步.为改变这种现状,在城市化发展过程中,应努力提高城市土地利用效率并发展经济,促进二者协调发展.     

道德对大学生违法犯罪的预防与抑制作用研究

在预防与抑制大学生违法犯罪的过程中,道德具有十分重要的作用。良好的社会公德意识是预防和抑制大学生违法犯罪的基础保证,中华民族优良道德传统资源具有不可或缺的珍贵价值。特别注重整体利益,强调对社会的责任意识;推崇“仁爱”原则,追求人际和谐;讲求谦敬礼让,强调克骄防矜;重视道德践履,强调修养的重要性等,这些都对预防、减少和抑制大学生违法犯罪有着重要的理论价值和现实意义。
