AbstractThe following problem is studied. The units of an inventory are used one by one until all have failed. Their lifetimes decrease with their ages, when they are taken out of the inventory. An item of age a is supposed to have a lifetime Y exp(‐a), where Y is a random variable which does not depend on a. It is shown that in order to maximize the total lifetime the items should be taken according to the LIFO principle. This is shown for a certain class of distributions of Y. This class includes the exponential and the Pareto distributions.

Many in Europe believe that large numbers of Turkish immigrants have failed to integrate into their host communities. How is this situation in Sweden? We found that most of the Turkish immigrants felt themselves to be Turkish and Sweden was accepted as a foreign country. Turkish-originated media was followed frequently and strong ties with relatives in Turkey were maintained. Marriage and friendship with native Swedes were not well accepted. We concluded that despite the multicultural aspects of Swedish integration policies, Turkish immigrants in Sweden were not well integrated and they prefer to live within the boundaries of their segregated, closed, small communities.
