Abstract

Purpose

The purpose of this paper is to investigate the thermal convection inside a spatially modulated domain.

Design/methodology/approach

The governing equations are mapped onto an infinite strip, allowing Fourier expansion of the flow and temperature in the streamwise direction.

Findings

Similar to Rayleigh‐Benard convection, conduction is lost to convection at a critical Rayleigh number, which depends strongly on both the modulation amplitude and the wavenumber. The effect of modulation is found to be destabilizing (stabilizing) for conduction for relatively large (small) modulation wavelength. Oscillatory convection sets in as the Rayleigh number is increased.

Originality/value

This paper presents novel results.

Abstract

Summarises the reasons behind the formation of a network and support group for self‐employed nutritionists (SENSE). Discusses the pros and cons of self‐employment, and shows how the formation of SENSE is one way in which a con can be turned into a pro. Gives points of contact for potential members and users of the services that SENSE members offer.

Abstract

Purpose

This paper examines the strategies that volunteers use when supporting asylum seekers with their information challenges to be able to develop services for asylum seekers and promote their access to reliable information in the most suitable way.

Design/methodology/approach

Semi-structured interviews were conducted with seven volunteers who help asylum seekers with their asylum cases in two cities in Finland. The interview data was thematically coded and analysed.

Findings

Six types of information-related strategies were identified: information mediatory, language adjustment, spatial and non-verbal communicative, inclusive, and supervisory strategies, as well as strategies with shifting roles. These strategies holistically support asylum seekers' information practices, considering the challenges of their situation and emotional needs.

Originality/value

This study creates new knowledge about volunteers' role in the information practices of asylum seekers, highlighting their unique position both in and outside the asylum system. Information-related strategies are a novel way of examining the ways to holistically support other people's information practices, by understanding that information is intertwined in all kinds of everyday actions and interactions.
