A sociocultural analysis of the development of pre-service and beginning teachersâ pedagogical identities as users of technology
This paper reports on a study that investigated the pedagogical practices and beliefs of pre-service and beginning teachers in integrating technology into the teaching of secondary school mathematics. A case study documents how one teachers modes of working with technology changed over time and across different school contexts, and identifies relationships between a range of personal and contextual factors that influenced the development of his identity as a teacher. This analysis views teachers learning as increasing participation in sociocultural practices, and uses Valsiners concepts of the Zone of Proximal Development, Zone of Free Movement, and Zone of Promoted Action to offer a dynamic way of theorising teacher learning as identity formation
Violent masculinities: Gendered dynamics of policing in Rio de Janeiro
Historically, policing in Rio de Janeiro has been shaped by the equation of racialized violence and masculinity. Attempts to reform the police have paradoxically drawn on forms of male violence that are centered on the rational and professional use of force and on âsofterâ practices, such as dialogue and collaboration, symbolically coded as feminine. The failure of police reform reflects the cultural salience of understandings of masculinity centered around violence within the police, historical patterns of policing in Rio, and political actorsâ strategic cultivation of male violence. Through Rio de Janeiro's failed attempt at police reform, we theorize the relation between racialized state violence, authoritarian political projects, and transgressive forms of male violence, arguing that an important appeal of authoritarianism lies in its promise to carve out a space for performing what we call wild masculinity.

Surveying the technology landscape: Teachers' use of technology in secondary mathematics classrooms
For many years, education researchers excited by the potential for digital technologies to transform mathematics teaching and learning have predicted that these technologies would become rapidly integrated into every level of education. However, recent international research shows that technology still plays a marginal role in mathematics classrooms. These trends deserve investigation in the Australian context, where over the past 10 years secondary school mathematics curricula have been revised to allow or require use of digital technologies in learning and assessment tasks. This article reports on a survey of mathematics teachers' use of computers, graphics calculators, and the Internet in Queensland secondary schools, and examines relationships between use and teachers' pedagogical knowledge and beliefs, access to technology, and professional development opportunities. Although access to all forms of technology was a significant factor related to use, teacher beliefs and participation in professional development were also influential. Teachers wanted professional development that modelled planning and pedagogy so they could meaningfully integrate technology into their lessons in ways that help students learn mathematical concepts. The findings have implications not only for resourcing of schools, but also for designing professional development that engages teachers with technology in their local professional contexts.

Pacification of Favelas, Mega Events and the Creation of New Inequalities in the Global South: The Case of Rio de Janeiro.
Since the 1980sâ in Rio de Janeiro, local authorities have conducted the so-called 'drug on war' policy, which has fought mainly within the favelas between the police and drug gangs occupying these territories. Because of the high level of violence that characterized the city since that time, it has been perceived globally as a âcity in warâ. In recent years, with the aim of attracting investors and private capital within the city, Rio de Janeiro's policy makers favoured a global-scale urban competitiveness strategy aimed at organizing mega events. In fact, the city hosted the Football World Cup in 2014 and the Olympics Games in 2016 mong others. However, in order to prove itself as a competitive city, Rio had to clean up its image as a âviolent placeâ. For this reason, in 2008 authorities created the âPacific Police Unitsâ, a program to recover some of the favelas previously occupied by criminal groups. This policy created inequalities for the lower strata of the population
