Understanding human-machine networks: A cross-disciplinary survey

© 2017 ACM. In the current hyperconnected era, modern Information and Communication Technology (ICT) systems form sophisticated networks where not only do people interact with other people, but also machines take an increasingly visible and participatory role. Such Human-Machine Networks (HMNs) are embedded in the daily lives of people, both for personal and professional use. They can have a significant impact by producing synergy and innovations. The challenge in designing successful HMNs is that they cannot be developed and implemented in the same manner as networks of machines nodes alone, or following a wholly human-centric view of the network. The problem requires an interdisciplinary approach. Here, we review current research of relevance to HMNs across many disciplines. Extending the previous theoretical concepts of sociotechnical systems, actor-network theory, cyber-physical-social systems, and social machines, we concentrate on the interactions among humans and between humans and machines. We identify eight types of HMNs: public-resource computing, crowdsourcing, web search engines, crowdsensing, online markets, social media, multiplayer online games and virtual worlds, and mass collaboration. We systematically select literature on each of these types and review it with a focus on implications for designing HMNs. Moreover, we discuss risks associated with HMNs and identify emerging design and development trends

#identity: Hashtagging Race, Gender, Sexuality, and Nation

"Since its launch in 2006, Twitter has served as a major platform for political performance, social justice activism, and large-scale public debates over race, ethnicity, gender, sexuality, and nationality. It has empowered minoritarian groups to organize protests, articulate often-underrepresented perspectives, and form community. It has also spread hashtags that have been used to bully and silence women, people of color, and LGBTQ people. #identity is among the first scholarly books to address the positive and negative effects of Twitter on our contemporary world. Hailing from diverse scholarly fields, all contributors are affiliated with The Color of New Media, a scholarly collective based at the University of California, Berkeley. The Color of New Media explores the intersections of new media studies, critical race theory, gender and women’s studies, and postcolonial studies. The essays in #identity consider topics such as the social justice movements organized through #BlackLivesMatter, #Ferguson, and #SayHerName; the controversies around #WhyIStayed and #CancelColbert; Twitter use in India and Africa; the integration of hashtags such as #nohomo and #onfleek that have become part of everyday online vernacular; and other ways in which Twitter has been used by, for, and against women, people of color, LGBTQ, and Global South communities. Collectively, the essays in this volume offer a critically interdisciplinary view of how and why social media has been at the heart of US and global political discourse for over a decade.

A Taste For Things: Sensory Rhetoric Beyond The Human

Amidst rising agricultural pollution, poor conditions for livestock animals, and disparity between “high” and “low” food cultures, gustatory taste has entered contemporary public rhetoric as a significant modality of intervention. This dissertation considers the environmentalist and social potential of this public embrace of sensory rhetoric. To do so, I build a rhetorical theory of sensation through a sensory re-engagement of the rhetorical tradition. Scottish Enlightenment thinkers, I argue, embraced aesthetic taste as a site where rhetoric and ethics mingle, and yet in promoting its cultivation, they fell into elitism. The subsequent, Marxist discourse on sensory emancipation developed rhetoric’s sensory and taste-based connections to ethics, taking an historical rather than an individualist perspective. I evaluate to what extent this discourse overcame Enlightenment elitism, and forge connections between the Marxist tradition and the current call among new materialists such as Bruno Latour for an immanent, compositionist reworking of critique. My final two chapters examine how a theory and critical practice of sensory rhetoric is elaborated in contemporary activist efforts from the industrial food exposé to the slow food and farm to school movements. Contributing to work in rhetoric and politics, my project provides an account of rhetoric’s materiality that closely links processes of materialization and practices of sensation. Contributing to work in rhetoric and ethics, I demonstrate that the ethico-rhetorical capacity for response abides not in the individual subject alone, but among all participants in the evolving zone of sensory contact. To the extent that those sensory collectives can recognize and embrace their ambient, inventive, and ever-evolving character, they harbor the potential to break with the Enlightenment ideal of a standard of taste and its associated elitism
