Despite the huge progress in scene graph generation in recent years, its long-tail distribution in object relationships remains a challenging and pestering issue. Existing methods largely rely on either external knowledge or statistical bias information to alleviate this problem. In this paper, we tackle this issue from another two aspects: (1) scene-object interaction aiming at learning specific knowledge from a scene via an additive attention mechanism; and (2) long-tail knowledge transfer which tries to transfer the rich knowledge learned from the head into the tail. Extensive experiments on the benchmark dataset Visual Genome on three tasks demonstrate that our method outperforms current state-of-the-art competitors.

A deep understanding of our visual world is more than an isolated perception on a series of objects, and the relationships between them also contain rich semantic information. Especially for those satellite remote sensing images, the span is so large that the various objects are always of different sizes and complex spatial compositions. Therefore, the recognition of semantic relations is conducive to strengthen the understanding of remote sensing scenes. In this paper, we propose a novel multi-scale semantic fusion network (MSFN). In this framework, dilated convolution is introduced into a graph convolutional network (GCN) based on an attentional mechanism to fuse and refine multi-scale semantic context, which is crucial to strengthen the cognitive ability of our model Besides, based on the mapping between visual features and semantic embeddings, we design a sparse relationship extraction module to remove meaningless connections among entities and improve the efficiency of scene graph generation. Meanwhile, to further promote the research of scene understanding in remote sensing field, this paper also proposes a remote sensing scene graph dataset (RSSGD). We carry out extensive experiments and the results show that our model significantly outperforms previous methods on scene graph generation. In addition, RSSGD effectively bridges the huge semantic gap between low-level perception and high-level cognition of remote sensing images.

The aim of this essay is to introduce, contextualize, and provide rationale for texts published in the Humanities special issue, Histories of Ethos: World Perspectives on Rhetoric. It surveys theories of ethos and selfhood that have evolved since the mid-twentieth century, in order to identify trends in discourse of the new millennium. It outlines the dominant theories—existentialist, neo-Aristotelian, social-constructionist, and poststructuralist—while summarizing major theorists of language and culture (Archer, Bourdieu, Foucault, Geertz, Giddens, Gusdorf, Heidegger). It argues for a perspectivist/dialectical approach, given that no one theory comprehends the rich diversity of living discourse. While outlining the “current state of theory,” this essay also seeks to predict, and promote, discursive practices that will carry ethos into a hopeful future. (We seek, not simply to study ethos, but to do ethos.) With respect to twenty-first century praxis, this introduction aims at the following: to acknowledge the expressive core of discourse spoken or written, in ways that reaffirm and restore an epideictic function to ethos/rhetoric; to demonstrate the positionality of discourse, whereby speakers and writers “out themselves” ethotically (that is, responsively and responsibly); to explore ethos as a mode of cultural and embodied personal narrative; to encourage an ethotic “scholarship of the personal,” expressive of one’s identification/participation with/in the subject of research; to argue on behalf of an iatrological ethos/rhetoric based in empathy, care, healing (of the past) and liberation/empowerment (toward the future); to foster interdisciplinarity in the study/exploration/performance of ethos, establishing a conversation among scholars across the humanities; and to promote new versions and hybridizations of ethos/rhetoric. Each of the essays gathered in the abovementioned special issue achieves one or more of these aims. Most are “cultural histories” told within the culture being surveyed: while they invite criticism as scholarship, they ask readers to serve as witnesses to their stories. Most of the authors are themselves “positioned” in ways that turn their texts into “outings” or performances of gender, ethnicity, “race,” or ability. And most affirm the expressive, epideictic function of ethos/rhetoric: that is, they aim to display, affirm, and celebrate those “markers of identity/difference” that distinguish, even as they humanize, each individual and cultural storytelling. These assertions and assumptions lead us to declare that Histories of Ethos, as a collection, presents a whole greater than its essay-parts. We conceive it, finally, as a conversation among theories, histories, analyses, praxes, and performances. Some of this, we know, goes against the grain of modern (Western) scholarship, which privileges analysis over narrative and judges texts against its own logocentric commitments. By means of this introduction and collection, we invite our colleagues in, across, and beyond the academy “to see differently.” Should we fall short, we will at least have affirmed that some of us “see the world and self”—and talk about the world and self—through different lenses and within different cultural vocabularies and positions.

This Introduction sets out the intentions of this book: to use the rich witch-trial records from the early modern duchy of Württemberg in south-western Germany to explore the central themes of emotions, gender, and selfhood. It provides an overview of the key historiographical debates on witchcraft persecutions in the early modern period, and suggests new questions that need to be asked. It also provides a methodological and theoretical framework in which to address these questions, and provides an overview of the current state of the field of the history of emotions, and, by drawing on psychological approaches to listening to self-narratives, it suggests ways in which historical studies of emotions can be pushed further by incorporating the body and subjective states. It also sets out the legal, political, and religious framework of the Lutheran duchy of Württemberg, in order to put the witch-hunts in this region into context.

The introduction to this book begins with a detailed description of what news fixers are and how their work has evolved over time. Since the book focuses primarily on news fixing in the 21st century, the introduction historicizes the figure of the fixer, illuminating the fixer’s connections to the interpreters or guides hired by explorers, missionaries, and anthropologists of past centuries. This brief but necessary historicization is firmly rooted within the critical framework of postcolonial studies, a theoretical lens that helps me explain the deeply entrenched tradition of colonial dependence on regionally specific knowledge—knowledge that unfortunately did not prevent the misrepresentation and exploitation of the people living in these other places. The introduction then moves to an examination of the news fixers’ current role within the larger ecosystem of international reporting. Building off the rich literature found in the field of journalism studies, which examines the various elements of the labor of foreign correspondence, the introduction will show that a space must be made within journalism scholarship for the study of news fixers. What is more, the field of global journalism ethics also has much to gain from a closer examination of these locally based media employees.
