Combatting electoral traces: the Dutch tempest discussion and beyond

In the Dutch e-voting debate, the crucial issue leading to the abandonment of all electronic voting machines was compromising radiation, or tempest. Other countries, however, do not seem to be bothered by this risk. In this paper, we use actor-network theory to analyse the socio-technical origins of the Dutch tempest issue in e-voting, and its consequences for e-voting beyond the Netherlands. We introduce the term electoral traces to denote any physical, digital or social evidence of a voter's choices in an election. From this perspective, we provide guidelines for risk analysis as well as an overview of countermeasures

Engagement in Philosophical Dialogue Facilitates Children’s Reasoning About Subjectivity

Theories of learning have long emphasized the essential role of social factors in the development of early reasoning abilities. More recently, it has been proposed that the presentation of conflicting perspectives may facilitate young children's understanding of knowledge claims as potentially subjective-one of many possible representations of the world. This development in epistemological understanding has been proposed to be an important determinant of academic performance and is highly correlated with the ability to understand and produce sound argumentation in adolescents and adults. In a longitudinal study of children 7-8 years old, we assessed the effects of a 3-month philosophy class designed to engage children in dialogic interaction with peers. We examined the influence of this intervention on children's epistemological understanding and argumentation skills in 4 domains of knowledge: aesthetic, value, social, and physical. Participation in dialogic interaction in an elementary school classroom improved children's ability to construct their own and opposing arguments across domains and facilitated reasoning about the subjectivity of knowledge in the value domain
