As venues for information sharing, SNS provide a diversity of communication capabilities and feedback features that can stir emotions, attitudes, beliefs, as well as influencing many decisions.

Following Schlenker (1999); Percus & Sauerland (2003b); Anand (2006), we assume the following semantics for attitude relations A:1 • A(λGλx′λw′ . p)(x)(w) = 1⇔ ∃G∀〈w′, x′〉 ∈ Ax . p(G)(x′)(w′) = 1 • 〈x′, w′〉 ∈ Doxx ⇔ x′ is an individual compatible with who x takes herself to be in w, and w′ is a world compatible with what x believes in w. • G is a variable over concept generators of type 〈e, 〈κ,...

The present study (a) examined the question of whether gender differences in hypothetical risk decisions might be socially facilitated by the presence of gender-homogenous groups and (b) investigated the conscious and non-conscious motivators of risk-taking through the application of both explicit and implicit measures of risk attitude. Using hypothetical choice dilemma items, no gender differe...

This attitude may be influenced by the attitudes of other pers...

In this paper, we show that a decision maker’s attitude towards ambiguity is similarly crucial for investment decisions. We capture the investor’s individual ambiguity attitude by applying α-MEU preferences to a sta...
