Social Cognitive Theory and Mass Media Effects
Bandura’s social cognitive theory is one of the most highly influential and widely celebrated theories in the field of social psychology. Thus, it is no surprise that its influence has extended into multiple fields, including communication and especially the study of media effects. Still, despite the enthusiasm with which media scholars have embraced social cognitive theory, its integration into media research is still in its infancy. The purpose of this chapter is first, to lay out the historical background and basic tenets of social cognitive theory. We will then explore the ways in which media effects scholars have integrated it into their research and consider the ways in which scholars might build on the existing foundation of social cognitive theory-based media research to better illuminate media effects processes and outcomes.https://scholarworks.wm.edu/bookchapters/1003/thumbnail.jp

Design and development of a complex narrative intervention delivered by text messages to reduce binge drinking among socially disadvantaged men
Background:
Socially disadvantaged men are at high risk of suffering from alcohol-related harm. Disadvantaged groups are less likely to engage with health promotion. There is a need for interventions that reach large numbers at low cost and which promote high levels of engagement with the behaviour change process. The aim of this study was to design a theoretically and empirically based text message intervention to reduce binge drinking by socially disadvantaged men.
Results:
Following MRC guidance, the intervention was developed in four stages. Stage 1 developed a detailed behaviour change strategy based on existing literature and theory from several areas. These included the psychological theory that would underpin the intervention, alcohol brief interventions, text message interventions, effective behaviour change techniques, narratives in behaviour change interventions and communication theory. In addition, formative research was carried out. A logic model was developed to depict the pathways between intervention inputs, processes and outcomes for behaviour change. Stage 2 created a narrative which illustrated and modelled key steps in the strategy. Stage 3 rendered the intervention into a series of text messages and ensured that appropriate behavioural change techniques were incorporated. Stage 4 revised the messages to ensure comprehensive coverage of the behaviour change strategy and coherence of the narrative. It also piloted the intervention and made final revisions to it.
Conclusions:
The structured, systematic approach to design created a narrative intervention which had a strong theoretical and empirical basis. The use of a narrative helped make the intervention realistic and allowed key behaviour change techniques to be modelled by characters. The narrative was intended to promote engagement with the intervention. The intervention was rendered into a series of short text messages, and subsequent piloting showed they were acceptable in the target group. Delivery of an intervention by text message offers a low-cost, low-demand method that can reach large numbers of people. This approach provides a framework for the design of behaviour change interventions which could be used for interventions to tackle other health behaviours

Boundedness of Lebesgue Constants and Interpolating Faber Bases
Background. We investigate the relationship between the boundedness of Lebesgue constants for the Lagrange polynomial interpolation on a compact subset of
and the existence of a Faber basis in the space of continuous functions on this compact set.
Objective. The aim of the paper is to describe the conditions on the matrix of interpolation nodes under which the interpolation of any continuous function coincides with the decomposition of this function in a series on the Faber basis.
Methods. The methods of general theory of Schauder bases and the results which describe the convergence of interpolating Lagrange processes are used.
Results. The structure of matrices of interpolation nodes which generate the interpolating Faber bases is described.
Conclusions. Every interpolating Faber basis is generated by the interpolating Lagrange process with the interpolating matrix of a special kind and bounded Lebesgue constants
