Income Inequality and Happiness: An Inverted U-Shaped Curve
Numerous studies agree that income inequality, rather than absolute income, is an important predictor of happiness. However, its specific role has been controversial. We argue that income inequality and happiness should exhibit an inverted U-shaped relationship due to the dynamic competing process between two effects: when income inequality is relatively low, the signal effect will be the domin...
متن کاملAlcohol and mortality: a U-shaped curve.
In a longitudinal study of civil servants, 1422 men were classified according to their average daily alcohol intake. Over 10 years of follow-up, the mortality rate was lower in men reporting moderate alcohol intake than in either non-drinkers or heavier drinkers (greater than 34 g alcohol per day). Cardiovascular mortality was greater in non-drinkers and non-cardiovascular mortality was greater...
متن کاملVitamin D and pancreatic cancer risk - no U-shaped curve.
In a recent paper entitled "Circulating 25-Hydroxyvitamin D and the Risk of Pancreatic Cancer," Stolzenberg-Solomon et al. reported that the odds ratio for diagnosis of pancreatic cancer shows a "statistically significant" precipitous jump of more than a factor of 2 at the highest presented concentrations of >100 nmol/l. This was one of six related studies of the relation of 25-hydroxyvitamin D...
متن کاملInverse U-shaped curve for age dependency of torsional eye movement responses to galvanic vestibular stimulation.
To investigate age dependent changes we analysed torsional eye movement responses to binaural and monaural galvanic vestibular stimulation (GVS) in 57 healthy subjects (20-69 years old). GVS (1-3 mA) induced torsional eye movements consisting of static torsion toward the anode (amplitude 1-6 degrees ) and superimposed torsional nystagmus (slow phase velocity 0.5-3 degrees /s, quick phase amplit...
متن کاملSpiraling down the river continuum: stream ecology and the U-shaped curve
The spiraling concept provides an explicit approach to modeling the longitudinal linkages within a river continuum. I developed a spiraling-based model for particulate organic C dynamics in the Little Tennessee River to synthesize existing data and to illustrate our current understanding of ecosystem processes in river ecosystems. The Little Tennessee River is a medium-sized river flowing ;100 ...
