Managing Demand Uncertainty through Core Acquisition in Remanufacturing

We discuss the optimal raw material acquisition strategy for a third party remanufacturer (3PR). We specifically investigate whether a 3PR should acquire used products or cores in bulk with uncertain quality levels, or in sorted grades with known quality levels; and whether to acquire and remanufacture cores before the demand is realized (planned acquisition), or after the demand is realized (reactive acquisition), or on both occasions (sequential acquisition). When only sorted cores are acquired, we find that, (i) it is optimal to acquire cores in multiple grades to balance acquisition and remanufacturing costs; (ii) if reactive acquisition is possible, it reduces the assortment size (number of grades in which cores are acquired) and the total inventory acquired in the planned acquisition; and (iii) the optimal portfolio of grades to acquire and the optimal acquisition and remanufacturing quantities of these grades can be determined analytically. When bulk cores are acquired in addition to sorted cores, the property of reduction in assortment size of the planned acquisition is preserved. We also show that the 3PR should acquire only a fraction of the demand in planned acquisition, and leave the rest for reactive acquisition. This fraction changes during the lifecycle of a remanufactured product. Using a combination of empirical and realistic data from a smartphone remanufacturer we show that sequential acquisition increases expected profit by up to 8% and 27% over only planned and only reactive acquisitions respectively, and reduces the inventory acquired by up to 21% over only planned acquisition.     

The impact of anti-Vietnam demonstrations upon national public opinion and military indicators

In an attempt to assess the national impact of anti-war protest, 15 major anti-Vietnam demonstrations occurring in the United States from 1965 through 1971 were analyzed for their effects upon Gallup public opinion survey data, American troop strength, and American munitions expenditures. While weak and short-term counterproductive effects appeared for two opinion indicators, an equally likely conclusion is that the demonstrations had little or no lasting impact whatsoever. The possible reasons for this finding, and its social implications, are discussed.     

Division of Responsibility in Care of the Aged

Not all elderly people need special care. This review refers to the dependent minority and to the services they need. Brief mention is made of the history of services which began with charitable relief by voluntary action, and the current relationship between government bodies and voluntary agencies is outlined. It is maintained that division of responsibility for the various types of care should be based on assessment of individual needs, decentralization of control, together with evaluation of the resources of the agencies concerned.     

Urban Dispersal in Australia

In a recent issue of the Journal, Professor R. E. Lonsdale argued that the relatively successful American experience of decentralization suggests serious difficulties in attempting a comparable programme in Australia. His comparisons, while illuminating many of the problems which must be faced by a realistic regional development policy, are unduly pessimistic in their assessment of the Australian situation. The barriers to urban dispersal in Australia lie less in economic and social conditions than in political attitudes and governmental structures.
