The Sznajd model for opinion dynamics has attracted a large interest as a simple realization of the psychological principle of social validation. As its most salient feature, it has been claimed that the Sznajd model is qualitatively different from other ordering processes because it is the only one featuring outflow of information as opposed to inflow. We show that this claim is unfounded by p...

We articulate the role of norms within the social identity perspective as a basis for theorizing a number of manifestly communicative phenomena. We describe how group norms are cognitively represented as context-dependent prototypes that capture the distinctive properties of groups. The same process that governs the psychological salience of different prototypes, and thus generates group normat...

This study provides insight into how social relationship factors influence on electronic Word-of-Mouth (EWOM) behaviors in social networking sites. By using the sample from Taiwan and Vietnam college students who spend more time on social networking sites, we investigate these determinants of EWOM behaviors such as social capital, trust and interpersonal influences, and compare the results betw...

In two experiments, we show how a consumer’s susceptibility to normative influence (SNI) offers useful insights into the effectiveness of two types of testimonials: a typical person endorsement (Study 1) and a celebrity endorsement (Study 2). Specifically, we suggest that two variables moderate testimonial effects—SNI and product attribute information. Results show that in forming their evaluat...

In Poland, invitro fertilisation technology (IVF) has been in use for over 25 years, garnering success and social approval. However, in 2007, a heated debate erupted on the moral, legal and economic aspects of IVF. A growing chorus of emphatic Catholic voices calls for IVF to be banned. This paper focuses on ‘naprotechnology’, a new actor and a fresh card in Poland’s IVF debate. This method of ...

This paper demonstrates the relevance of consumers’ susceptibility to interpersonal influence (CSII) in an investment context. In Study 1, a survey of individual investors, investment-related knowledge, psycho-social risks, and social needs emerge as antecedents that explain investors’ susceptibility to informational and normative influence. In turn, susceptibility to normative influences incre...

We show how different approaches to developing marketing strategies depend on the type of environment a firm faces, where environments are distinguished in terms of their systems properties rather than their content. Particular emphasis is given to turbulent environments in which outcomes are not a priori predictable and are not traceable to individual firm actions and we show that, in these co...

BACKGROUND Public health recommendations are usually based on a mixture of empirical evidence and normative arguments: to argue that authorities ought to implement an intervention that has proven effective in improving people's health requires a normative position confirming that the authorities are responsible for improving people's health. While public health (at the national level) is based ...

The study of norms (Ns) is recent but growing concern in the AI field (cf. [MOS92]; [SHO92]) as well within other formal approaches to social action, such as Game Theory (where theories of Ns began to appear long before, cf.[LEW69]; [ULL77]). The normative is an essential dimension of social life. An explicit model of such dimension is crucial for any theory of social action. Notions such as "s...

This article is a sequel to our earlier work [24]. The main objective of our research is to explore the potential of supervised machine learning in face-induced social computing and cognition, riding on the momentum of much heralded successes of face processing, analysis and recognition on the tasks of biometric-based identification. We present a case study of automated statistical inference on...
