Wetting transition of grain-boundary triple junctions

admin — Wed, 17 Sep 2008 06:33:17 +0000

The wetting phase transition of grain boundaries (GBs) and grain-boundary triple junctions (GB TJs) by the melt has been studied in the Al�30 wt.%Zn and Al�10 wt.%Zn�4 wt.%Mg polycrystals. The condition of complete wetting is weaker for TJs (?GB > ?SL) than that for GBs (?GB > 2?SL), ?GB being the GB energy and 2?SL being the energy of the solid/liquid interphase boundary. As a result the temperature of TJ wetting transition should be lower than that of GB wetting transition TwGB. It has been experimentally observed for the first time that TJs become completely wetted at TwTJ, which is about 10�15 �C below TwGB.

Lately, sports stars like linebacker Ray Lews (near right) have been in the news for arrests instead of athletic achievements. Many team owners say they would like to crack down on these players, but labor laws and contracts make discipline difficult The NFL, though, is taking the lead in efforts to tackle these problems.

When Sandra Day O’Connor sought her first law job/she could only find work as a legal secretary. Women have come a long way since then. They now represent half of incoming law students and almost a third of all lawyers. Our report explores gains made and problems that remain

WHICH WAY FOR THE ADA?

The 10-year-old Americans With Disabilities Act is suffering from growing pains. Court decisions have narrowed its reach and aided employers, who win most ADA discrimination cases. Now a U.S. Supreme Court case and legislative proposals could further limit the act. But activists like John Kemp (right) say don’t tamper with it.

WHERE WILL THEY GO?

Just days before hostilities erupted in the Middle East, an ABA Journal reporter accompanied three Palestinian refugees across the Israeli border to visit their ancestral village. like the Abu Laban family (right), they seek a right to return home. International law is on the refugees* side, but it may be ignored at the bargaining table. Without resolution, the refugee camps will likely remain flash points for unrest.

WHEN DOES DECISION AUTONOMY INCREASE EXPATRIATE MANAGERS’ ADJUSTMENT? AN EMPIRICAL TEST.

admin — Tue, 16 Sep 2008 23:47:09 +0000

To enhance understanding of expatriate adjustment, we examine the effect of the decision autonomy afforded to expatriate managers on their own adjustment as well as the moderating effect of global integration pressure. We further investigate the mitigating effect of a parent company’s operational experience with a particular foreign subsidiary on this relationship. We examine these issues using survey data from 187 expatriate general managers and 24 corporate headquarter executives working in the global hotel industry. The results of the study support the hypotheses postulated. We discuss implications of these findings.
