A model for the control of the European grapevine moth Lobesia botrana includes two control methods: insecticides and mating disruption. It yields the combination and schedule of application that minimize cost and losses due to the pest. A simulation is presented for an experimental situation. 相似文献

Missing data pose a serious challenge to the integrity of randomized clinical trials, especially of treatments for prolonged illnesses such as schizophrenia, in which long‐term impact assessment is of great importance, but the follow‐up rates are often no more than 50%. Sensitivity analysis using Bayesian modeling for missing data offers a systematic approach to assessing the sensitivity of the inferences made on the basis of observed data. This paper uses data from an 18‐month study of veterans with schizophrenia to demonstrate this approach. Data were obtained from a randomized clinical trial involving 369 patients diagnosed with schizophrenia that compared long‐acting injectable risperidone with a psychiatrist's choice of oral treatment. Bayesian analysis utilizing a pattern‐mixture modeling approach was used to validate the reported results by detecting bias due to non‐random patterns of missing data. The analysis was applied to several outcomes including standard measures of schizophrenia symptoms, quality of life, alcohol use, and global mental status. The original study results for several measures were confirmed against a wide range of patterns of non‐random missingness. Robustness of the conclusions was assessed using sensitivity parameters. The missing data in the trial did not likely threaten the validity of previously reported results. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

ABSTRACTIn settler nations such as Australia, which have high migrant intakes, a category of cultural heritage practice has emerged that focuses on the material record of immigration. Currently, a nation-bounded approach tends to be taken to the recording and interpretation of this heritage, an approach that largely ignores the transnational social fields to which the immigrants who created the heritage places and buildings belonged. I propose the concept ‘heritage corridor’ to aid in conceptualising the transnational connectivity between migrant heritage sites in Australia and overseas locales as well as the bi-directional flow of ideas and capital that is often materially evident in the built environments, both rural and urban, encompassed by such a corridor. Focusing on Chinese overseas migration in the nineteenth and twentieth centuries, I describe how transnational remittances were instrumental in the building of houses, temples, schools, shops, roads and bridges in Guangdong Province, many of which are now regarded as heritage items. As an example of how the field of heritage studies may productively dialogue with migration studies, new thinking on material agency is drawn upon to account for the way remittance-built houses become entangled in the lives and aspirations of those at opposite poles of a heritage corridor. 相似文献

This paper proposes a comparison of the results of tax policy analysis obtained on the basis of unitary and collective representations
of the household. We first generate labour supplies consistent with the collective rationality, by use of a model calibrated
on microdata as described in Vermeulen et al. [Collective Models of Household Labor Supply with Nonconvex Budget Sets and
Nonparticipation: A Calibration Approach (2006)]. A unitary model is then estimated on these collective data and unitary and collective responses to a tax reform are compared.
We focus on the introduction of linear taxation in Germany. The exercise is replicated for other European countries and other
topical reforms. Distortions due to the use of a unitary model turn out to be important in predicting labour supply adjustments,
in the design of tax revenue neutral reforms, and in predicting a reform’s welfare implications.

A new rank test family is proposed to test the equality of two multivariate failure times distributions with censored observations. The tests are very simple: they are based on a transformation of the multivariate rank vectors to a univariate rank score and the resulting statistics belong to the familiar class of the weighted logrank test statistics. The new procedure is also applicable to multivariate observations in general, such as repeated measures, some of which may be missing. To investigate the performance of the proposed tests, a simulation study was conducted with bivariate exponential models for various censoring rates. The size and power of these tests against Lehmann alternatives were compared to the size and power of two other tests (Wei and Lachin, 1984 and Wei and Knuiman, 1987). In all simulations the new procedures provide a relatively good power and an accurate control over the size of the test. A real example from the National Cooperative Gallstone Study is given 相似文献
