We have calculated two new sets of weights applicable to the General Household Survey (GHS) from 1979 to 2007. One of these is for use with any general analysis of GHS topics and the second is designed for analyses of data collected in the Family Information section. The methods used follow closely those employed by ONS from 1996 onwards. The performance of the weights is assessed in estimating the Total Fertility Rate (TFR) from 1971-2007, an aggregate measure of fertility for which reliable figures are available at national level from vital registration statistics. Our weights improve the GHS estimates, reducing bias both in the TFR and in age-specific fertility rates.  相似文献

A multiobjective routing model for Multiprotocol Label Switching networks with multiple service types and traffic splitting is presented in this paper.The routing problem is formulated as a multiobjective mixed-integer program,where the considered objectives are the minimization of the bandwidth routing cost and the minimization of the load cost in the network links with a constraint on the maximal splitting of traffic trunks.Two different exact methods are developed for solving the formulated problem,one based on the classical constraint method and another based on a modified constraint method.Avery extensive experimental study,with results on network performance measures in various reference test networks and in randomly generated networks,is also presented and its results are discussed.  相似文献

The purpose of this paper is to review recent developments in critical theory on the political function of the public sphere and the emancipatory potential of new social movements. This work is shown to be relevant to systemic decisions made under conditions of public conflict. Normative models for the self-understanding of actors engaged in self-limiting emancipatory struggles in modern societies are reviewed and related to the concerns of Critical Systems Thinking.  相似文献

Boulding's Skeleton of Science (a systems framework) is used to demonstrate first that several levels of disciplines are necessary for holistic research, and secondly that this can be applied to addressing issues concerning emerging infectious disease (EID). A literature review gathered a list of possible contributing risk factors for EID. Those factors were matched to the levels of disciplines in Boulding's Skeleton of Science to show that different risk factors must be studied by a combination of disciplines to adequately address the occurrence of infectious disease. An analysis of one international health policy document is also included to determine the range of disciplines represented in that document. Using a multidisciplinary (systemic) approach demonstrated advantages that complement and overcome the limitations of modern epidemiology. Recommendations for the inclusion of a multidisciplinary epidemiological approach are made, followed by some reflections on the conclusions drawn from this research, and suggestions for future work.

In this paper we examine how soft systems methodology (SSM) can benefit the initial identification and communication of new computer game concepts between those involved in its development. Computer games are a multi‐billion pound worldwide part of the entertainment industry. However, they are a relatively new type of software product and as such the manner in which they are designed and developed is still evolving. Computer games can be highly complex software systems that involve the expertise of a wide range of professionals ranging from programmers to animators, artists and musicians. When designing computer games, new game concepts can be difficult to communicate. In addition, the creative process could be benefited if game design ideas were capable of being shared widely and discussed. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Learning organisation literature has widely discussed the connections between “double-loop” learning and its significance to organisational performance, but paying little attention to tools and systems that can operationalise “double-loop” learning in organisations. This paper investigates the impact of applying a systems approach for service operations design, expressed as the Vanguard Method (Seddon, Freedom from command and control: a better way to make the work work, 2003), in order to activate “double-loop” learning in service organisations. Two case studies were conducted in the banking mortgage operations and adults’ social care services in the UK, using the dimensions of the learning organisation questionnaire (DLOQ), semi-structured interviews, observations, and documents. The findings of the cross-case analysis support the link of applying the Vanguard Method with operationalising “double-loop” learning through three main factors, namely systematic-operations improvement, organisational capacity development, and outside-in mode of work; that are all embedded into the seven dimensions of the DLOQ. The value of this paper is the introduction of a service operations design tool that can activate “double-loop” learning performance in the fast changing knowledge era. It also provides an impetus for service organisations to creatively influence employees’ competencies to effectively improve internal systems.  相似文献
