Our classificationEcological values
Operationalization
Discrepancy between the actual homestead food 
production and the selfrated importance of country 
ascetism

HFP:percentage of a family's food that the respondents 
reported was produced on ther mini-homesteads

CA: Selfreport on degree of country asceticism
Items include importance of:
- having a gas or electric clothes dryer
- having an indoor tilet or bathroom
- living in a modern house
- having electricity in your home
- having a microwave oven
Rated 1 (very important) to 4 (not at all important)

GAP: The value scales and performance indexes were 
dichotomized at their empirical midpoints (medians) and 
then cross-tabulated with each other. The survey 
respondents then fell into one of four categories: (1) 
low values/low performance (“no gap”), (2) high 
values/low performance (“gap”), (3) low values/high 
performance (“gap”), and (4) high values/high 
performance (“no gap”). These gaps (or absence of gaps) 
are calculated for both performance indicators (TSR 
Index and HFP) and for each of the three value scales 
(Country Asceticism, Homestead Production and 
Ecological Sensitivity). 
The first step to the comparability of the variables is 
to normalize each indicator and then place the 
respondents’ scores along a normalized distribution as 
t-scores with means of 50 and standard deviations of 
10. With respondents possessing comparable scores for 
each of the key indicators which constitute the 
values-performance discrepancies, a “gap score” for 
each value-performance pair was calculated by 
subtracting normalized performance scores from 
normalized value scores.
To faciliate interpretation they just used a subsample 
with values higher than the median for Technological 
Self-Reliance Index (TSR), Country Ascetisism (CA), 
Homestead Production (HP) and Ecological Sensitivity 
(ES) for further analysis

Appendix 2: Statistics used
SymbolExplanation
BetaSTANDARDIZED REGRESSION COEFFICIENT by LEAST SQUARES (OLS)
Type: test statistic.

Measurement level: Correlates: all metric, Happiness: metric.
Range: [-1 ; +1]

Meaning:
beta > 0 « a higher correlate level corresponds to a higher happiness rating on average.
beta < 0 « a higher correlate level corresponds to a higher happiness rating on average.
beta = 0 « no correlation.
beta = + 1 or -1 « perfect correlation.
rPRODUCT-MOMENT CORRELATION COEFFICIENT (Also "Pearson's correlation coefficient' or simply 'correlation coefficient')
Type: test statistic.
Measurement level: Correlate: metric, Happiness: metric
Range: [-1; +1]

Meaning:
r = 0 « no correlation ,
r = 1 « perfect correlation, where high correlate values correspond with high happiness values, and
r = -1 « perfect correlation, where high correlate values correspond with low happiness values.
