We study an economy where agents are heterogeneous in terms of observable wealth and unobservable talent. Adverse selection forces creditors to ask for collateral. We study the two-way interaction between rationing in the credit market and the wages offered in the labor market. Both pooling and separating credit contracts can be offered in equilibrium. The minimum wealth needed to obtain a sepa...

BACKGROUND As elderly populations grow, dementia detection in the community is increasingly needed. Existing screens are largely unused because of time and training requirements. We developed the Mini-Cog, a brief dementia screen with high sensitivity, specificity, and acceptability. Here we describe the development of its scoring algorithm, its receiver operating characteristics (ROC), and the...

The aim of this study was to examine the association between parent and child anxiety sensitivity in the context of parenting behaviors, specifically by testing parenting behaviors as moderators or mediators of the association between parent and child anxiety sensitivity. Past research implies that parent anxiety sensitivity may be more related to child anxiety sensitivity (moderation) in girls...

conclusions considering the level of learning motivation among the students in aspects of self-efficacy conception, self-management, and communication abilities, it is recommended to provide programs to develop these characteristics by cooperative learning method based on social constructivism theory. patients and methods this descriptive cross-sectional study was conducted on the rehabilitatio...

The ability to find one's way in our complex environments represents one of the most fundamental cognitive functions. Although involving basic perceptual and memory related processes, spatial navigation is particularly complex because it is a multisensory process in which information needs to be integrated and manipulated over time and space. Not surprisingly, humans differ widely in this abili...

The human ability to echolocate differs between individuals. Blind perform significantly better then sighted. There is very limited research on psychological factors underlying this ability. This study is based on earlier research by Schenkman and Nilsson (2010). The research questions in the present study were whether blind individuals perform better then sighted on general cognitive tasks, if...

A new exploration of the cortical network underlying our language abilities by Hauk et al., in this issue of Neuron, shows that the process of giving meaning to words differentially activates the motor cortex according to the semantic category of the word.

Anxiety sensitivity (AS) is a risk factor for the development of anxiety disorders in youth. To date, the applicability of the Childhood Anxiety Sensitivity Index (CASI) in youth from a low or middle income country (LMIC) setting on the African continent has not been assessed. A representative sample of 1149 secondary school learners from 29 schools in Cape Town, South Africa, participated in t...

Cloud single scattering properties are mainly determined by the effective radius of the droplet size distribution. There are only few exceptions where the shape of the size distribution affects the optical properties, in particular the rainbow and the glory directions of the scattering phase function. Using observations by the Compact Airborne Spectrographic Imager (CASI) in 180 backscatter geo...
