BACKGROUND Few of the many behavioral sexual health interventions in Africa have been rigorously evaluated. Where biological outcomes have been measured, improvements have rarely been found. One of the most rigorous trials was of the multi-component MEMA kwa Vijana adolescent sexual health programme, which showed improvements in knowledge and reported attitudes and behaviour, but none in biolog...

The present study presents an Industry 4.0 measurement model that is applied to a sample of Portuguese companies from several economic sectors beyond manufacturing. An scale developed through three-step methodology relies on mixed-methods approach. Five constructs are identified literature, together with respective indicators: IT strategy and cybersecurity, enablers, smart factory, value propos...

MIS researchers have developed a number of models for studying the software utilization choices of end users, including the Task-Technology Fit Model and the Technology Acceptance Model. We are exploring the similarities and differences among these models with a goal of developing combined models with more explanatory power. This paper proposes a model that extends the task-technology fit model...

In this paper we formalize sanction-based obligations in the context of Searle’s notion of construction of social reality. In particular, we define obligations using a counts as conditional, Anderson’s reduction to alethic modal logic and Boella and Lesmo’s normative agent. Our analysis presents an alternative criticism to the weakening rule, which has already been criticized in the philosophic...

A major challenge in tissue engineering is the lack of proper vascularization of the fabricated tissue constructs. Microscale technologies, especially microfluidic systems, provide new opportunities to overcome the challenge of developing artificial micro-vasculatures. In this chapter, the application of microfluidic systems for generating vascularized tissue constructs by using microfluidic pl...

Every day we are confronted with social interactions with other people. Our social life is characterised by norms that manifest as attitudinal and behavioural uniformities among people. With greater awareness about our social context, we can interact more efficiently. Any theory or model of human interaction that fails to include social concepts could be suggested to lack a critical element. Th...
