In this paper the mechanism of Default Rules for narrowing-based languages proposed in 24] is adapted to lazy narrowing. Every partial deenition of a function can be completed with a default rule. In a concrete function call, the default rule is applicable when the normal ones determine that they cannot compute the value of the call. Furthermore , when the goal has variables the evaluation mech...

This paper tests a key theoretical prediction of public finance, that redistribution discourages the participation of productive individuals. 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 findings support the theoretic...

in this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{a}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{a}(t)) dt +mathbf{c}$. we also observe that the effective force $mathbf{f}_e$ on that particle due to pseudo-force $mathbf{a}(t)$, is given by $ mathbf{f}_e= mathbf{f} mat...
