Set-point theory is the main research paradigm in the field of subjective well-being (SWB). It has been extended and refined
for 30 years to take in new results. The central plank of the theory is that adult set-points do not change, except temporarily
in the face of major life events. There was always some ‘discordant data’, including evidence that some events are so tragic
(e.g. the death of one’s child) that people never regain their set-point. It was possible to dismiss these events as ‘exceptions’
and maintain the theory. However, several new findings are emerging, which cannot be dismissed as ‘exceptions’ and which appear
to require substantial revisions or replacement of set-point theory. Many of these findings are based on the German Socio-Economic
Panel Survey (SOEP 1984-), which provides the longest available time series on life satisfaction. Despite its centrality,
the concept of the set-point is often not precisely defined. In this paper three alternative working definitions are offered.
Depending on which definition is used, it is found that over 20 years 14–30% of German panel members recorded large and apparently
permanent changes in their set-points. Changes of this magnitude are not compatible with set-point theory as currently understood.
The challenge for SWB researchers now is to develop a theory which can account for change as well as stability. 相似文献

ABSTRACTAnnual net cash returns and net capital gains provide farmers with their actual and potential monetary rewards, respectively. This article reports on a national farm survey showing both actual and potential returns, on average, are not as high as might be imagined. This is supported by the findings of earlier studies and has implications for rural societies and their associated economies. Data on income, expenses and profit is presented as is data on farm value changes over the life of each farm. The information is adjusted for inflation to provide ‘real’ data. The profit and net capital gain figures are divided into groupings based on a range of criteria such as total farm capital, and labour compliment as a reflection of farm size. Statistically significant differences occur for some groupings such as farm type and farm size. 相似文献

A Theory for Coloring Bivariate Statistical Maps 总被引:1,自引:0,他引:1
Bruce E. Trumbo 《The American statistician》2013,67(4):220-226
Consideration of some practical uses of statistical bivariate maps—for example, display of association between variables—leads to principles for making effective use of color to represent data values. Effective color schemes for bivariate maps are viewed as continuous transformations from color models to the unit square with appropriate restrictions involving hue, saturation, and brightness. Several schemes, including those used by the U.S. Census Bureau, are criticized on the basis of this theory. 相似文献

We describe a method of computing the cumulative distribution function of the maximum and minimum cell frequencies in sampling distributions commonly encountered in the analysis of categorical data.The procedure is efficient for exact or approximate calculation in both homogeneous and non-homogeneous cases, is non-recursive, and does not require Dirichlet integrals.Some related statistical problems are also discussed. 相似文献
