We test whether induced mood states have an effect on elicited risk and time preferences in a conventional laboratory experiment. We jointly estimate risk and time preferences and find that subjects induced into a negative mood exhibit economically significant higher risk aversion than those in the control treatment. Those in the positive mood treatment exhibit even higher risk aversion. We fin...

In this paper, we define the concept of incomplete hesitant fuzzy preference relations to deal with the cases where the decision makers express their judgments by using hesitant fuzzy preference relations with incomplete information, and investigate the consistency of the incomplete hesitant fuzzypreference relations and obtain the reliable priority weights. We first establish a goal programmin...

Cognitive ecology is a term that has been used in environments that are more tightly coupled and purposespecific than environments of everyday life. In this paper I consider cases from a cognitive ethnography of older adults. These cases show the analytical use of understanding the diachronic and synchronic cognitive ecology in which cognitive processes of everyday life occur. Specifically I di...

A fitness landscape presents the relationship between individual and its reproductive success in evolutionary computation (EC). However, discrete and approximate landscape in an original search space may not support enough and accurate information for EC search, especially in interactive EC (IEC). The fitness landscape of human subjective evaluation in IEC is very difficult and impossible to mo...

Motivations for owning rural land are shifting from an agricultural-production orientation to a preference for natural and cultural amenities. Resultant changes in land management have significant implications for the type and distribution of landscape-level disturbances that affect the delivery of ecosystem services. We examined the relationship between motivations for owning land and the impl...

In order to evaluate the landscape and its agrarian components in the low mountainous region of the Alpujarras in Southeastern Spain, Conjoint Analysis (C.A.) was used, and both ranking and rating approaches were considered as a way of assessing preferences. Data was obtained from a preference test carried out with a sample survey of 165 visitors to the area. Three main landscape components wer...

We describe a web-based system to support groups in elaborating participatory budgets. Rather than using physical meetings with voting mechanisms, we promote virtual meetings with explicit preference elicitation, guided negotiations and, only if consensus is not reached, vot-

South African law recognises a financial claim against a health provider for negligently failing to advise an expectant mother that she might give birth to a child suffering from a severe health condition or congenital disability. In December 2014, the Constitutional Court handed down a judgment that could lead to financial claims by the child, who was subsequently born with a severe health con...

The contribution of sexual selection to diversification remains poorly understood after decades of research. This may be in part because studies have focused predominantly on the strength of sexual selection, which offers an incomplete view of selection regimes. By contrast, students of natural selection focus on environmental differences that help compare selection regimes across populations. ...
