Specifically, I use a longitudinal data set to test whether and to what extent the intensive redistribution practiced by Israeli kibbutzim encourages exit of more productive individuals and entry of less productive ones.

The 90Sr and 137Cs contamination in Polish surface waters has been monitoring since 1994. Surface water samples from six lakes and the Vistula and Oder Rivers were collected in spring and autumn 2012 and 2013. The mean 90Sr and 137Cs concentrations were 3.92 ± 0.40 and 4.49 ± 2.00 mBq L-1, respectively. Correlations were identified between the radionuclide concentrations and meteorological cond...

This work treats the case of expert-originated hypotheses which are to be modified or refined by training event data. The method accepts the hypotheses in the form of weighted VL, expressions and uses the probabilistic rule generator, PRG. The theory of operation, verified by experimental results, provides for any degree of hypothesis modification, ranging from minor perturbation to complete re...

Imagine that you and a peer form an opinion in isolation about whether P in response to mutually shared evidence, and you take your peer to be just as reliable as you about matters of this kind.
