An injective finite mapping is an abstraction common to many programs. We describe the design of an injective finite mapping and its implementation in Curry, a functional logic language. Functional logic programming supports the concurrent asynchronous execution of distinct portions of a program—a condition that prevents passing from one portion to another the structure containing a partially c...

In this paper, we undertake the first examination of the effects of personality on individual economic choices over public environmental goods, using a stated preference approach. Based on three data sets from three separate choice modelling studies, we examine the effects of personality on preferences for the status quo, for changes in environmental quality, and over the costs of investing in ...

The hippocampus is said to be involved in "navigation" and "memory" as if these were distinct functions. In this issue of Neuron, Singer et al. (2013) provide evidence that the hippocampus retrieves spatial sequences in support of memory, strengthening a convergence between the two perspectives on hippocampal function.

No research has examined the challenges faced by lesbian women seeking to adopt from the perspective of lesbian couples themselves. The current qualitative study utilized data from 70 women (from 35 same-sex couples) who were in the process of adopting to explore how lesbian women experience and navigate the challenges they encounter during this critical life transition. Ecological, minority st...

This paper identifies the optimal mortgage choice of homeowners, who are subject to counter-cyclical income volatility and idiosyncratic income risk. The market equilibrium of investors with similar income risk exposures, leads to pro-cyclical equilibrium interest rates. The key determinant of the optimal mortgage choice is the correlation of income with the business cycle. Homeowners with high...

This study examined age-related changes in a specific aspect of adolescent decisionmaking, namely the preference for future versus immediate outcomes. A sample of 622 Dutch adolescents aged 12 -17 years completed a temporal discounting task. Participants were asked to choose between a delayed reward of €50 or an immediate reward of lower value. The delay interval was varied in three blocks (1 w...

In recent years, psychologists have started to investigate the downstreamconsequences of nonconsciously activated behaviour (acting in an ‘explanatory vacuum’). Results have shown that when such behaviour is norm-violating, people experience a need to confabulate reasons for this behaviour. The present paper aims to add more convincing evidence for this assumption. Study 1 addresses this questi...

A common problem with systems that use passwords for authentication results when users choose weak passwords. Weak passwords are passwords that arc easy to guess, or likely to be found in a dictionary attack. Thus, the choice of weak passwords may lead to system compromisation. Methods exist to prevent users from selecting and using weak passwords. One common method is to compare user choices a...
