Discrepancy between the actual use of technology and 
the selfrated importance of homestead production

TSR: Selfreport on which degree the technologies 
provided their family with self-reliance or 
independence
Respondents were presented with 25 soft-technologies 
and asked whether they possessed or used the 
technologies, for example:
   - garden
   - goats
   - greenhouse
   - composting toilets
   - photo voltaic
Rated 1 (not at all effective) to 4 (very effective)
TSR is calculated by multiplying each technology 
possessed by the efficiency rating claimed for the 
particular technology
theoretical range from 0 - 100

HP: Selfreport on the importance of homestead 
production:
- growing your own food
- cutting energy consumption
- growing/eating organic food
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

Beta controlled for
- gap: importance of homestead food production / 
actual homestead food production
- gap: importance of ecological sensitivity / 
actual use of technology
- gap: importance of ecological sensitivity / 
actual homestead food production
- gap: importance of cultural ascetism / actual 
homestead food production
