We consider spatial point processes with a pair correlation function, which depends only on the lag vector between a pair of points. Our interest is in statistical models with a special kind of ‘structured’ anisotropy: the pair correlation function is geometric anisotropic if it is elliptical but not spherical. In particular, we study Cox process models with an elliptical pair correlation function, including shot noise Cox processes and log Gaussian Cox processes, and we develop estimation procedures using summary statistics and Bayesian methods. Our methodology is illustrated on real and synthetic datasets of spatial point patterns. 相似文献

In recent years, the Australian university sector has undergone large-scale organizational change, including restructuring, downsizing and government funding cuts. At the same time, research from across the globe reports an alarming increase in the occupational stress experienced by university staff. We report on the first phase of a longitudinal investigation of occupational stress. A total of 22 focus groups were conducted with a representative sample of 178 academic and general staff from 15 Australian universities. The groups focused on understanding staff 's experience of occupational stress, and perceptions of the sources, consequences and moderators of stress. Both general and academic staff reported a dramatic increase in stress during the previous 5 years. As a group, academic staff reported higher levels of stress than general staff. Five major sources of stress were identified including: insufficient funding and resources; work overload; poor management practice; job insecurity; and insufficient recognition and reward. The majority of groups reported that job-related stress was having a deleterious impact on their professional work and personal welfare. Aspects of the work environment (support from co-workers and management, recognition and achievement, high morale, flexible working conditions), and personal coping strategies (stress management techniques, work/ non-work balance, tight role boundaries and lowering standards), were reported to help staff cope with stress. The findings provide a timely insight into the experience of stress within universities. 相似文献

This paper describes a model for allocating the weekly requirement of manpower for maintenance jobs in the process units. We develop a simple procedure for the solution of the manpower allocation problem which has to deal with planned and unplanned jobs during a planning period. The solution procedure is illustrated by a numerical example. Possible extensions of this model are also discussed. 相似文献

This paper considers Ackoff's Fables, a set of short stories published by Ackoff in 1978 as guides to creative problem solving. The paper argues that storytelling of this kind contributes usefully to management and MS/OR education, before addressing how such Fables might be interpreted. It is demonstrated, using one of Ackoff's Fables, The Smart Jackass, for illustrative purposes, that interpretation of even apparently straightforward stories such as these is not unambiguous. The Fables can be interpreted in a multitude of different and sometimes contradictory ways, and the truths they might contain are not self-evident. Yet, as the basis for discussion, they still have much to offer as educational tools. The paper concludes with a discussion of literal truth in stories, and presents a classification of story types according to their relationship to literal truth. 相似文献

The paper seeks to examine the site of performance, the spatial context of the dramatic act, and to consider the various ways in which performance is regulated, ordered and sustained. In particular, the paper is concerned with the relationship between authority and propriety in the regulation of the performance site and with the transformational metaphors which sustain the trajectory of the performance. The basic premise on which the argument rests is that there is a equivalence of sign-imagery as appropriate to liturgical performance which is the basis of some forms of organisational behaviour and that this equivalence permits more than the mere playing out of ritualistic behaviour: it appropriates the image in the reproduction and re-presentation of its forms. Consequently, the significance of the elevation, for instance, of The Cross or the consecrated Host, the notion of ritualistic cleansing, of humiliation, of redemptive acts, of public confession, become emblematic means of achieving organisational incorporations and of achieving movement from the isolated “I” to the collective “We”. 相似文献

The likelihood ratio method is used to construct a confidence interval for a population mean when sampling from a population with certain characteristics found in many applications, such as auditing. Specifically, a sample taken from this type of population usually consists of a very large number of zero values, plus a small number of nonzero values that follow some continuous distribution. In this situation, the traditional confidence interval constructed for the population mean is known to be unreliable. This article derives confidence intervals based on the likelihood-ratio-test approach by assuming (1) a normal distribution (normal algorithm) and (2) an exponential distribution (exponential algorithm). Because the error population distribution is usually unknown, it is important to study the robustness of the proposed procedures. We perform an extensive simulation study to compare the percentage of confidence intervals containing the true population mean using the two proposed algorithms with the percentage obtained from the traditional method based on the central limit theorem. It is shown that the normal algorithm is the most robust procedure against many different distributional error assumptions. 相似文献
