Operationalization | 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 they were asked to which degree the technologies provided their family with self-reliance or independence (on a four-point-scale from 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 |

Observed distribution | Range 0 - 72, Mean 20, Average item possession 6,8, Median item possession 6,0, Mean effectiveness rating 2,9 |

Appendix 2: Statistics used

Symbol | Explanation |

Beta | STANDARDIZED 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. |

r | PRODUCT-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. |
