基于回归技术商品销售趋势预测模型的实现

运用统计技术进行预测分析是数据挖掘领域的一项重要任务。利用线性回归建模技术、最小二乘法以及在线分析处理（OLAP）技术,设计并实现了基于回归技术的商品销售预测模型。并且利用该模型从海量数据库中挖掘出决策支持知识。     

Promoting psychosocial adaptation of youths in residential care through animal-assisted psychotherapy

The goal of this study was to examine the influence of animal-assisted psychotherapy (AAP) on the psychosocial adaptation of a group of adolescents in residential care who had suffered traumatic childhood experiences and who presented with mental health problems. This study recruited 63 youths (mean age = 15.27, SD = 1.63) who were divided into two groups: a treatment group of 39 youths (19 female and 20 male; mean age = 15.03, SD = 0.51) and a control group of 24 (five female and 19 male; mean age = 15.67, SD = 1.63). The youths who underwent the AAP program had higher school adjustment in comparison to their peers who did not receive treatment. Their hyperactive behavior decreased, and they showed better social skills, more leadership, and fewer attention problems. They also showed a more positive attitude toward their teachers in comparison to controls. No differences were observed in other variables associated with clinical symptoms or personal adjustment. These results suggest that AAP can be effective with teenagers who have suffered childhood traumas and who present with problems of psychosocial adaptation.     

论一物一权原则

起源于罗马法的一物一权原则是大陆法系国家物权法的基本原则。但随着社会和经济的发展,一物一权理论及其基本原则地位受到了严峻挑战。从分析一物一权原则的界定出发,结合具体案例,论证一物一权原则在现代社会中存在的必要性。然后利用一物一权原则对现代社会的特定现象进行解释,并提出完善一物一权原则的对策,旨在为一物一权原则在现代社会的健康发展提供有力的理性支持。

美国高校宿舍教育的历史分析：宿舍与人才培养

美国高校学生宿舍从早期承担的生活功能、管理功能,到近50年才开拓的教育功能,走过了漫长的历史。殖民时期,受英国牛津剑桥模式的影响,采用住宿学院制,宿舍主要作用是代替父母监督;内战结束后至19世纪后期,受德国大学影响,认为为学生提供宿舍没有意义;19世纪后期至20世纪中期,伴随赠地学院的发展,宿舍建设再次兴起,这个时期宿舍主要作用是为学生提供生活服务;20世纪60年代以后,宿舍教育功能被广泛认可,开始有目的地设计宿舍教育环境,宿舍成为学生课堂教育与非课堂教育的衔接,成为促进学生全面发展的教育资源。
