南方黑人，客体化的财产

威廉·福克纳是20世纪美国最为杰出的作家之一,1950年诺贝尔文学奖获得者。在他的作品《去吧,摩西》中,福克纳以其独特的视角塑造了有着浓厚地方性与历史性特征的南方黑人形象,深刻揭露了南方的奴隶制和种族主义,表达了对南方黑人的同情、尊重和关心。     

The relationship between fundamental movement skill proficiency and physical self-confidence among adolescents

This study aims to assess fundamental movement skill (FMS) proficiency, physical self-confidence levels, and the relationship between these variables and gender differences among adolescents. Three hundred and ninety five adolescents aged 13.78 years (SD = ±1.2) from 20 schools were involved in this study. The Test of Gross Motor Development-2nd Edition (TGMD), TGMD-2 and Victorian Skills Manual were used to assess 15 FMS. Participants’ physical self-confidence was also assessed using a valid skill-specific scale. A significant correlation was observed between FMS proficiency and physical self-confidence for females only (r = 0.305, P < 0.001). Males rated themselves as having significantly higher physical self-confidence levels than females (P = 0.001). Males scored significantly higher than females in FMS proficiency (P < 0.05), and the lowest physical self-confidence group were significantly less proficient at FMS than the medium (P < 0.001) and high physical self-confidence groups (P < 0.05). This information not only highlights those in need of assistance to develop their FMS but will also facilitate in the development of an intervention which aims to improve physical self-confidence and FMS proficiency.     

关于动物保护的法律思考

近年来对动物保护的呼声日趋高涨。西方有思想家认为,生物圈中所有事物都应该拥有生存繁荣和自我实现的平等权利。我国则有学者提出赋予动物权利主体的地位。笔者不赞同“动物主体论”主张,并从环境伦理学、民法的基本理念、欧盟国家动物保护的立法、我国动物保护的立法现状与思考等四方面展开对动物保护的法律思考。     

基于负样本多通道优化SSD网络的钢铁厂提取

准确提取钢铁厂对去产能监测和环境保护具有重要意义。传统的人工目视解译方法效率低、成本高,无法满足开展大区域钢铁厂监测的需求。以深度学习目标检测网络SSD为基础,构建面向遥感影像钢铁厂提取的深度学习目标检测网络,提出maxout模块,将负样本通路优化为多分支结构,突出难分负样本特征并提升网络对无用特征的抵制效果。利用国产GF-1数据对京津冀地区的钢铁厂进行快速自动提取实验。与人工解译的钢铁厂点位数据的对比表明,该目标检测方法的提取精度达到80%以上。     

基于深度学习的SSD模型尾矿库自动提取

针对华北地区尾矿库自动提取问题,将基于深度学习的SSD目标检测模型应用于遥感图像尾矿库提取。首先标记华北地区2 000个样本,随机挑选1 500个作为训练样本,剩余样本作为测试样本,验证模型的检测精度。分析卷积层对应感受野与图像中尾矿库尺寸关系,发现原始SSD模型漏检误检大型尾矿库。改进SSD模型结构,提出增加额外卷积层的策略,提高对大型尾矿库目标的检测精度。实验表明,在置信度阈值为0.3时,改进的SSD模型相比原始模型,检测精确率提高10.0%,召回率提高14.4%,提高了大型尾矿库检测精度。验证了基于深度学习的SSD目标检测模型自动提取尾矿库的可行性以及改进算法的有效性。

论成人教育的服务功能及其实现路径

成人教育存在的价值在于向社会提供服务,因此服务体现了成人教育功能的本质。成人教育服务具有对象广泛、内容多元、形式多样和领域社会化等特征。当前,成人教育发展困境的根源在于服务难以体现自身的特色,成人教育应通过更新发展理念、提高服务质量、扩大服务对象和开发服务项目来促进服务功能的实现。     

在"本质"的纷争中认识图书馆学研究对象

图书馆学研究对象的纷争,表现最突出、最有影响的是持论者强调图书馆的某一本质为研究对象,文章认为,研究对象之一即是图书馆的本质,但是具体的本质又不属于“图书馆学研究对象”这一命题。

Generalized Hamming Distance

Many problems in information retrieval and related fields depend on a reliable measure of the distance or similarity between objects that, most frequently, are represented as vectors. This paper considers vectors of bits. Such data structures implement entities as diverse as bitmaps that indicate the occurrences of terms and bitstrings indicating the presence of edges in images. For such applications, a popular distance measure is the Hamming distance. The value of the Hamming distance for information retrieval applications is limited by the fact that it counts only exact matches, whereas in information retrieval, corresponding bits that are close by can still be considered to be almost identical. We define a Generalized Hamming distance that extends the Hamming concept to give partial credit for near misses, and suggest a dynamic programming algorithm that permits it to be computed efficiently. We envision many uses for such a measure. In this paper we define and prove some basic properties of the Generalized Hamming distance, and illustrate its use in the area of object recognition. We evaluate our implementation in a series of experiments, using autonomous robots to test the measure's effectiveness in relating similar bitstrings.
