Risk factors for fatal and non-fatal child maltreatment in families previously investigated by CPS: A case-control study

The objective of this study was to identify individual, family and caregiver risk factors for serious child maltreatment, resulting in hospitalization or death, among children and families investigated by Child Protective Services (CPS). We conducted a matched case-control study of 234 children who sustained fatal or serious nonfatal maltreatment due to physical abuse or neglect and whose mother was named in a CPS investigation between 1999 and 2013. A total of 702 children and their caregivers were included in the study with 234 cases matched 2:1,resulting in 468 controls. Data on potential risk factors were abstracted from three county administrative databases. Differences between cases and controls were calculated and multivariable conditional logistic regression was used to estimate risk models. Variables associated with increased risk for serious maltreatment included male child gender,younger caregivers, three or more children under the age of 5 living in the home, families in which a biologic child was not living with either parent, and scoring moderate or high on the Structured Decision Making Risk Tool^®. Caregiver involvement in intimate partner violence (IPV) and child enrollment in public health insurance appears to mitigate the risk of serious maltreatment.     

体育范式浅论

运用劳丹的分析哲学体系,结合逻辑分析手段,从分析模糊的"体育"这一日常词汇入手,剥离出体育的硬核和保护带,进而定义体育的内涵,建立起一个体系下的范式.建立一套科学、系统、严谨的体育范式是解决体育之争的前提和基础.学术之争应建立在一定的范式之上.一门学科应有自己的研究基点.交叉学科也应有自己的硬核和保护带.     

基于Faster R-CNN的服装目标检测改进方法

为了满足近年来在服装电子商务高速发展背景下急剧增长的服装图像分类与定位需求,实现对服装图像的目标检测,提出基于Faster R-CNN的服装目标检测改进方法。借助残差神经网络的特征提取能力进行服装图像特征提取,采用RPN网络进行服装候选区域生成,经过RoI兴趣区域池化后接入分类层与回归层,调整网络结构,融合服装图像的HOG底层特征,从而针对性地实现对服装图像的目标检测。实验结果表明,该方法构建模型的平均准确率为0.902,运行速度为8.9帧/秒,具有一定的实用价值。
