Given relatively high levels of adherence to HIV treatment in Africa, we explore factors facilitating children's adherence, despite poverty, social disruption and limited health infrastructure. Using interviews with 25 nurses and 40 guardians in Zimbabwe, we develop our conceptualisation of an 'adherence competent community', showing how members of five networks (children, guardians, community ...

This article proposes a theory- and practice-based model for adapting physical activities. The ecological frame of reference includes Dynamic and Action System Theory, World Health Organization International Classification of Function and Disability, and Adaptation Theory. A systematic model is presented addressing (a) the task objective, (b) task criteria, (c) limitation and enablement criteri...

The selection of bootloaders for embedded systems has expanded since the late 1990s; not just in the number of bootloaders on the market, but also in the number of platforms and operating systems supported by each bootloader. This article stands as a guide to selecting a bootloader for embedded systems to aid in reaching time-to-market goals by reducing redundant system, debugging, and feature ...

The larger effort began when a number of communities (the CDM work at Unidata, the CSML work at BADC, and the OGC Sensor Web Enablement Observations and Measurements) realized they were developing similar lists of data types. The combined list includes: 1) grid, 2) point/station observation, 3) vertical profile/sounding, 4) trajectory, 5) swath, and 6) radar/radial. This paper details the curre...

Infrastructures (persistent socio-technical systems over which services are delivered) are normally taken for granted by their users, but are powerful forces of constraint and enablement with implications for the design, use, and adoption of ubiquitous computing. To approach the study of infrastructure from an ethnographic perspective, we conducted an exploratory field study of people for whom ...

INTRODUCTION Medically unexplained symptoms (MUS) are very common in family medicine, despite being a poorly-defined clinical entity. This study aimed to evaluate the effect of an educational intervention (EI) on self-rated quality of life, treatment satisfaction, and the family physician-patient relationship in patients with MUS. METHODS In a multi-centre longitudinal intervention study, whi...

I Introduction What is the epistemic significance of discovering that one of your beliefs depends on an irrelevant causal factor? Suppose that you have a relatively high degree of belief in some proposition. Suppose that you then come to learn that your belief was (in part) caused by an irrelevant factor, a factor that does not bear on the truth of the proposition or on your possession of evide...

This comment on Valsiner’s (2003) theory of enablement appreciates the theory’s contribution to fill the lacuna of social representation theory in dealing with individual reasoning and behaviour through a mechanism of semiotic mediation. It is shown, however, that the experimental illustration of the theory falls slightly short of providing evidence for the claims. In re-interpreting the experi...

Knowledge sharing is crucial to the success of knowledge management systems. Information technologies and incentives are important to effectively manage knowledge assets in organizations. In this paper, we study the joint role of incentives and information technologies in enabling knowledge sharing and learning. We investigate two organizational knowledge-transfer policies: mandatory learning a...
