Facilitating the take-up of new HCI practices: a ‘diffusion of innovations’ perspective

The workshop Made for Sharing: HCI Stories of Transfer, Triumph & Tragedy focuses on collecting cases in which practitioners have used their HCI methods in new contexts. For analyzing the collected body of cases we propose to apply a framework inspired by the Diffusion of Innovations approach which focuses on what facilitates the adoption, re-invention and implementation of new practices in social systems

A framework to analyze argumentative knowledge construction in computer-supported collaborative learning

Computer-supported collaborative learning (CSCL) is often based on written argumentative discourse of learners, who discuss their perspectives on a problem with the goal to acquire knowledge. Lately, CSCL research focuses on the facilitation of specific processes of argumentative knowledge construction, e.g., with computer-supported collaboration scripts. In order to refine process-oriented instructional support, such as scripts, we need to measure the influence of scripts on specific processes of argumentative knowledge construction. In this article, we propose a multi-dimensional approach to analyze argumentative knowledge construction in CSCL from sampling and segmentation of the discourse corpora to the analysis of four process dimensions (participation, epistemic, argumentative, social mode)

Hate Speech, Historical Oppressions, and European Human Rights

Today, around 5 billion people communicate through the Internet. While the benefits of online communication are undeniable, we also witness the proliferation of online hate speech, often associated with an increase in offline violence. Internet intermediaries and public bodies have developed frameworks to counter online hate speech. However, current frameworks lack a standardized approach to the conceptualization of hate speech. Some conceptualizations are overbroad, and others are underinclusive; overbroad because they lead to the removal of legal content (e.g. removal tools deleting legal content posted by marginalized communities), and underinclusive as the context of posts by linguistic minorities is often disregarded. This Article proposes a new legal conceptualization of hate speech in the European context. It does so by analyzing the European regulatory framework through the lens of the first legal conceptualizations of hate speech deriving from critical (race) theory and (black) feminist intersectionality theory. The European focus is justified by the need to standardize at the regional level the legal requirements in current and future policies to counter online hate speech. The methodology is doctrinal, normative, and meta-legal. There are two main findings. First, this Article suggests that the European regulatory framework needs to explicitly acknowledge the conceptualization of hate speech by critical legal scholars as expressions intended to perpetuate historical or systematic oppression. Second, this Article advocates that the conceptualization of hate speech in the European context can only achieve legal cohesion when all European regulatory instruments expressly account for the intersectionality of systems of oppression

Software Engineering Challenges for Investigating Cyber-Physical Incidents

Cyber-Physical Systems (CPS) are characterized by the interplay between digital and physical spaces. This characteristic has extended the attack surface that could be exploited by an offender to cause harm. An increasing number of cyber-physical incidents may occur depending on the configuration of the physical and digital spaces and their interplay. Traditional investigation processes are not adequate to investigate these incidents, as they may overlook the extended attack surface resulting from such interplay, leading to relevant evidence being missed and testing flawed hypotheses explaining the incidents. The software engineering research community can contribute to addressing this problem, by deploying existing formalisms to model digital and physical spaces, and using analysis techniques to reason about their interplay and evolution. In this paper, supported by a motivating example, we describe some emerging software engineering challenges to support investigations of cyber-physical incidents. We review and critique existing research proposed to address these challenges, and sketch an initial solution based on a meta-model to represent cyber-physical incidents and a representation of the topology of digital and physical spaces that supports reasoning about their interplay
