TSR-Ecological Sensitivity Gap
Our Classification
Discrepancy between Technological Self Reliance and Ecological Sensitivity

Technological Self Reliance. The index is calculated by multiplying tools or technology, possessed by a
respondent by the efficiency rating claimed for the particular technology, resulting in the sum of the efficiency rating for each of the 25 tools.The tools are:, 2. greenhouse, 3.root cellar, pond, 5. solar heat, 6.pigs, 7.wood lot, 8.wood stove heat, 9.wood stove cooking, 10.composting privy, 11.hydro-electric system, 12.graywater(waste water) water heater, 14.chickens, 15.goats, 16.beef cattle, 17.milk cow(s) 18.sheep, 19.wind power, 20.weeder geese, 21.bees, 22.fruit trees, 23.butcher larger anaimals, voltaic power, horses.
Efficiency is evaluated by asking the respondents about the effectiveness of the tool items of 'providing your family with independence or self-reliance from a one (not at all effective) to four(very effective point sequence. The TSR index-scores have a theoretical range betwee 0-100

Ecological Sensitivity is importance of: 1. The expansion of wilderness areas; 2.preserving old growth forests; 3. Providing habitat for endangered species; 4. Recycling newspapers; 5. Reducing personal energy consumption.

GAP between value and performance is constructed by dichotomizing the value scale and performance indexes at their respective medians and to cross these indicators with each other. The respondents will fall in one of the four categories:
a. No gap, low values-low TSR
b. gap,    high values-low TSR
c. gap,    low values-high TSR
d. no gap, high values-high TSR.
