This paper examines the role of technoscientific speculation in large-scale development projects in postcolonial spaces, building on recent work in STS, design research, and postcolonial studies in and beyond CSCW. We analyze two historical cases of technology-infused development projects in the Canadian province of Newfoundland and Labrador and in Jamaica. We find that speculation in these contexts remixes the constructive stance toward speculation typical for normative technoscience with the critical, contesting orientation of speculative design. Conflicts between these stances are resolved by leveraging fantasy for pragmatic ends, grounding audacious fictions in imported realities, unmooring from conventional understandings of linear technological progress, and using even conservative futures to trouble colonial conventions.

Through their combination of lifestyle and method, Silicon Valley models for tech production such as design thinking, startup incubators, lean management, etc. are spreading across the globe. These paradigms are positioned by product designers, politicians, investors and corporations alike as replicable routes to individual and national empowerment. They are portrayed as universal templates, portable across national borders and applicable to local needs. We draw from our ethnographic engagements with tech entrepreneurial efforts in Ghana, China, and Jamaica to unpack the stakes involved in their uptake, showing that while local actors produce situated alternatives, their work nevertheless often results in a continued valorization of these seemingly universal methods. We argue that design methods shape not only use practices, but have consequences for the life worlds of professional designers. This includes how they impact personal and national identities, confer legitimacy in transnational innovation circles, and secure access to social and economic resources. Ultimately, we call for an inclusion of these factors in ongoing conversations about design and design methods.

Despite the abundance of research on social networking sites, relatively little research has studied those who choose not to use such sites. This paper presents results from a questionnaire of over 400 Internet users, focusing specifically on Facebook and those users who have left the service. Results show the lack of a clear, binary distinction between use and non-use, that various practices enable diverse ways and degrees of engagement with and disengagement from Facebook. Furthermore, qualitative analysis reveals numerous complex and interrelated motivations and justifications, both for leaving and for maintaining some type of connection. These motivations include: privacy, data misuse, productivity, banality, addiction, and external pressures. These results not only contribute to our understanding of online sociality by examining this under-explored area, but they also build on previous work to help advance how we conceptually account for the sociological processes of non-use.

This is a critical design paper offering a possible scenario of use intended to provoke reflection about values and politics of design in persuasive computing. We describe the design of a system - Fit4Life - that encourages individuals to address the larger goal of reducing obesity in society by promoting individual healthy behaviors. Using the Persuasive Systems Design Model [26], this paper outlines the Fit4Life persuasion context, the technology, its use of persuasive messages, and an experimental design to test the system's efficacy. We also contribute a novel discussion of the ethical and sociocultural considerations involved in our design, an issue that has remained largely unaddressed in the existing persuasive technologies literature [29].
