基于 GCN 的安卓恶意软件检测模型

函数调用图存在规模过大、无关信息过多等缺陷。为实现函数调用图的高效分析,对安卓恶意软件的恶意代码模式进行挖掘,提出一种基于图卷积神经网络（GCN）的敏感 API 调用模式,并设计相应的函数调用图精简方法,以及敏感 API 权重评价方法,有效降低了函数调用图规模,实现对敏感 API 调用模式的挖掘。检测模型综合了安卓恶意软件操作码特征、敏感权限特征、敏感函数调用频度特征,构建了基于多特征融合的安卓恶意软件检测系统,进一步提升了检测精度。数据集测试验证了 API 调用模式特征以及集成检测模型的有效性。

Update: The Invisible Farmer: securing Australian farm women’s history

This article reviews the Invisible Farmer project – the largest study of Australian women on the land – a third of the way through its three year funding period. It introduces the aims of this collaborative and multidisciplinary project, focusing on the role of records and oral histories in the creation of new narratives, and the task of raising public awareness of the important historical and contemporary contributions made by Australian women farmers. We examine the way digital platforms work to curate records and promote research, and outline the important role that the Australian Women’s Register, a core project of the Australian Women’s Archives Project, will play in achieving outcomes.     

Network member support marshaling in response to another’s relational transgression experience

Relational transgressions are emotionally difficult for those who directly experience the transgression. Less is known about how transgressions affect those located within the personal network of a relational transgression victim. This study explored how network members engaged in support marshaling in response to another’s transgression experience. Results indicate that some participants marshaled support, citing four reasons for their actions: perceived insufficiency, camaraderie, personal ramifications, and personal values. We explore these reasons for marshaling support and discuss them within the broader context of support marshaling and relational transgressions.     

Core–periphery structures in national higher education systems. A cross-country analysis using interlinking data

This paper presents a comparative analysis of the structure of national higher education networks in six European countries using interlinking data. We show that national HE systems display a common core–periphery structure, which we explain by the lasting reputational differences in science, as well as the process of expansion and integration of HE systems. Furthermore, we demonstrate that centrality in national networks (coreness) is associated with organizational characteristics, reflecting that interlinking is motivated by access to resources and the status of the organizations concerned, and that national policies impact network structures by influencing the level of inequality in the distribution of resources and status. Finally, we show that, as an outcome of the core–periphery structure, the strength of ties between two HEIs is largely determined by their individual coreness, while the impact of distance is too small-scale to alter the network structure generated by organizational attributes.
