Abstract. In this article we consider a problem from bone marrow transplant (BMT) studies where there is interest on assessing the effect of haplotype match for donor and patient on the overall survival. The BMT study we consider is based on donors and patients that are genotype matched, and this therefore leads to a missing data problem. We show how Aalen's additive risk model can be applied in this setting with the benefit that the time‐varying haplomatch effect can be easily studied. This problem has not been considered before, and the standard approach where one would use the expected‐maximization (EM) algorithm cannot be applied for this model because the likelihood is hard to evaluate without additional assumptions. We suggest an approach based on multivariate estimating equations that are solved using a recursive structure. This approach leads to an estimator where the large sample properties can be developed using product‐integration theory. Small sample properties are investigated using simulations in a setting that mimics the motivating haplomatch problem. 相似文献

Much discussion and writing about “systems” is often superficial, glib, and of a non-operational nature. This paper presents a cohesive framework for the process of system design which is felt to be of operational value in the design and management of systems. The framework's central tenet is that all systems are made up of entities and the relationships among the attributes of those entities; and that in designing systems, two processes are used, inclusion and structuring. Inclusion is concerned with what entities to include in a system and structuring with how their attributes are to be related. The system design process is directed or driven by a set (system) of criteria. Systems must be viewed with a time dimension: evolution will and should take place, both in the systems themselves and, more importantly, in the criteria that drive the design and evolution of those systems. In this framework, all problem solvers can usefully regard themselves as system designers. Presentation of the framework is followed by examples, discussion of the criteria set, system design tools, and some implications for teachers and practitioners. 相似文献

This exploration of the evolution of the International Shipwreck Society (ISS) – a previously neglected transnational humanitarian organization that by the late 1830s had branches in every continent – casts new light on three key aspects of the development of global humanitarianism. First, that there was a secular humanitarian association with a global organizational structure in the 1830s challenges widespread assumptions about the timing of internationally organized humanitarian action. Second, the influence of Chinese precedents on the ISS points to the importance of long forgotten Eastern origins of transnational humanitarianism. And third, the evaluation of the role of individuals in the development of the ISS reveals that early transnational humanitarian organizations faced leadership problems that scholars had previously neglected. In each of these respects, this article provides a new perspective on the origins of global networks. 相似文献

In this historical analysis of U.S. trade policy, we apply the median voter model to explain legislative decision making. In this model, the level of tariff protection is expected to change with changes in the median legislator. We show that this simple model does a remarkable job if explaining trade policy until the mid-1930s, when it breaks down. We offer several possible explanations for the breakdown of this model, focusing particularly on the impact of domestic and international institutional changes that may have altered the role of the median legislator in trade policy formation. 相似文献
