One such issue is the ＂identity crisis＂ also known as the question of ＂Who is a Jew？＂. This is a thorny complex problem, and one which has not yet been awarded a clear-cut constitutional solution. For example, it continues to be debated whether the religious definition should be the decisive factor, that is, should a Jew defined as an individual born to a mother who is Jewish or has been converted according to halacha, or whether Israeli identity is the more critical element and whether any individual born in or immigrated to Israel who served in the army, works and pays taxes in Israel, and identifies with the state＇s values should be identified as a Jew？ In this paper, the author wishes to focus on equally complicated issue, although one has attracted less attention. This is the issue of halachic polarization or extremism that characterizes Judaism in modem Israel. Following a brief historical explanation, the author defines the problem at hand, and propose a solution.展开更多

Now it is widely known that probabilistic and non-probabilistic uncertain information exists in engineering analysis. Based on reliability comprehensive index of multi-ellipsoid convex set, probabilistic uncertain information is added and transferred into non-probabilistic interval variable. The hybrid reliability is calculated by a combined method of modified limit step length iteration algorithm(MLSLIA) and Monte-Carlo method. The results of engineering examples show that the convergence of MLSLIA is better than that of limit step length iteration algorithm(LSLIA). Structure buckling hybrid reliability increases with the increase of ratio of base diameter to cavitator diameter, and decreases with the increase of initial launch velocity. Also the changes of uncertain degree of projectile velocity and cavitator drag coefficient affect structure buckling hybrid reliability index obviously. Therefore, uncertain degree of projectile velocity and cavitator drag coefficient should be controlled in project for high structure buckling reliability.展开更多
