传统的否定选择算法无法有效识别落入到低维子空间的样本,导致算法在高维空间检测性能不佳。为此,提出了面向子空间的否定选择算法(subspace-oriented negative selection algorithm,SONSA)。在训练常规检测器的基础上,SONSA将搜索样本分布密度较高的低维子空间以进一步训练面向子空间的检测器,从而提高算法对低维子空间内样本的识别能力。实验结果表明,在标准数据集Haberman’s Survival(三维)与Breast Cancer Wisconsin(九维)上,相对于经典的V-Detector算法以及采用PCA降维的V-Detector算法,SONSA能在误报率相似的情况下显著地提高检测率。

新时代下,中国公益慈善事业发生了新的转型,呈现出治理吸纳慈善的总体特征。治理吸纳慈善的核心是国家汲取能力,国家汲取能力是国家治理能力的重要组成部分。在新时代的公益慈善事业中,公益慈善组织正从以往分类控制体系下发挥拾遗补阙作用的角色逐渐成为社会治理的重要主体,为国家治理战略目标服务,国家汲取能力也通过治理吸纳慈善得以体现和深化。汲取资源的范畴突破了传统资源观的局限,逐渐向意识形态、行政管控及战略资源领域延伸。在治理吸纳慈善下,国家与社会达成了深层次的合作与嵌入关系:国家通过意识形态的吸附、行政监管及战略资源的运用有效地汲取了社会资源,而社会组织的合法性与战略位置也被提升到一个前所未有的高度。治理吸纳慈善的总体特征促使那些相对独立的草根组织发生了新的转向:回归社区、回归志愿者的自组织、回归传统慈善以及让商业和企业家担负起自己的公益使命成为民间公益转向的重要形式。

中国举国体制下的新冠疫情防控中,建立健全突发公共事件应急管理的社会组织参与渠道日趋重要。对新冠肺炎疫情社区防控的多案例研究发现,国内社会组织的社区防疫行动总体上表现出嵌入式发展、网络化协同、多业态融合、信息化运作、强化关键节点等特征,且不约而同地聚焦于社区互助网络的构筑。这类作为社会自救机制的社区互助网络,由居民、志愿者、社区自治组织、社区社会组织、业主组织、物业公司等多元行动主体所组成,促进了社区共同体的形成。参与、链接与支持社区互助网络的形成,进而培育社区共同体,成为疫情治理中关于社会组织参与社区防控效能的最大启示。进一步看,重视枢纽性社会组织的建设,引导社区共同体的发展,开展日常化的社区工作,重视舆论作用是未来社会组织促进疫情治理中出现的社区共同体常态化的有效途径。
