People differ in their lay theories about how and why the financial well-being of individuals changes over time or varies between individuals. We introduce a measure of Causal Attributions of Financial Uncertainty-the CAFU scale-and find that such attributions can be described reliably along three distinct dimensions, respectively capturing the extent to which changes in financial well-being are perceived to be: (a) knowable and within individuals' control due to individual factors such as effort ("Rewarding"); (b) knowable and outside of individuals' control due to factors such as favoritism and discrimination ("Rigged"); and (c) inherently unpredictable and determined by chance events ("Random"). In a sample representative of the U.

People often neglect opportunity costs: They do not fully take into account forgone alternatives outside of a particular choice set. Several scholars have suggested that poor people should be more likely to spontaneously consider opportunity costs, because budget constraints should lead to an increased focus on trade-offs. We did not find support for this hypothesis in five high-powered experiments (total N = 2325).

Purpose: Sometimes, a conventional recess-resect surgery may not be sufficient to obtain satisfactory ocular alignment. Patients who have previously undergone surgery and/or have a large difference in visual acuity between both eyes and do not wish to undergo surgery on the sound eye provide a surgical challenge. In these cases, tendon elongation with bovine pericardium may be an option.

Purpose: The purpose of this study was to investigate the role of (hyperopic or myopic) spectacle correction in reading speed of 9- to 10-year-old children.

Methods: Subjects were recruited at their schools. Initial selection was based on reduced distance acuity and/or a positive blur test.

Toxicity of aggregation-prone proteins is thought to play an important role in aging and age-related neurological diseases like Parkinson and Alzheimer's diseases. Here, we identify tryptophan 2,3-dioxygenase (tdo-2), the first enzyme in the kynurenine pathway of tryptophan degradation, as a metabolic regulator of age-related α-synuclein toxicity in a Caenorhabditis elegans model. Depletion of tdo-2 also suppresses toxicity of other heterologous aggregation-prone proteins, including amyloid-β and polyglutamine proteins, and endogenous metastable proteins that are sensors of normal protein homeostasis.
