The purpose of this research is to increase understanding of Taylor's six-segment strategy wheel (SSSW) by exploring how message strategy makes use of commenters' parasocial interactions (PSIs) with social media influencers (SMIs). Recent research findings have concluded that younger viewers often consider PSIs/parasocial relationships (PSRs) to be highly similar to their social interactions/relationships. To understand this phenomenon, the research explores the dynamics of the vaping community, because SMIs are a primary means of product information. Vaping companies use SMIs who are known only to the collective group of like-minded peers to create a loyal audience. The present study uses research from the SSSW and PSIs to understand persuasive cues while watching a video featuring an SMI. [ABSTRACT FROM AUTHOR]

The effects of water-soluble nonstarch polysaccharides (sNSP) on human metabolism are considered to be beneficial because they decrease postprandial glycaemia and insulinaemia following ingestion of starch-rich foods. The mechanisms by which sNSP attenuate the postprandial rise in blood glucose are not well understood but their presence increases the viscosity of gastrointestinal contents, which affects physiological functions, e.g. gastric emptying and peristalsis. Increased viscosity and decreased water activity during hydrothermal treatment of starch could influence α-amylase action.Using guar galactomannan as a representative of sNSP, we found that galactomannan has a direct noncompetitive inhibitory effect on α-amylase with a Ki value of approximately 0.5% (3.3 μM). The inhibition is not time dependent and studies suggest direct binding of the enzyme to galactomannan; the resulting galactomannan–amylase complex being inactive. Processing of starch at low water levels greatly affects the catalytic efficiency of α-amylase. The Km value for starch heat treated in limited water is raised and kcat is lowered relative to starch gelatinised in excess water. Since galactomannan has no effect on the Km of α-amylase, we conclude that the inhibitory action of the polymer is not secondary to a decrease in available water. Neither does it seem to be a consequence of impaired diffusion of enzyme, substrate and products because of an increase in viscosity of the medium.Thus, the effects of sNSP in lowering postprandial glycaemia not only involve modifications of gut physiology, but also include direct inhibition of the first stage in the biochemical degradation of starch.
