Is Hypermobility a Challenge for Transport Ethics and Systemicity?   总被引:2,自引:0,他引:2  
Modern modes of transport, in the developed world, were designed to achieve higher mobility (or speed) and increased accessibility, all in the name of growth and human progress. However, in the course of providing for this higher mobility, through the rapid expansion of the transport system, we have ended up with a condition of imbalanced mobility, which we refer to as "hypermobility," particularly with reference to the automobile mode. Ironically, this very expansion of the transport network, with the objective of providing higher transport speeds, has resulted in traffic congestion that has drastically reduced mobility and accessibility, thereby lowering business productivity, increasing fuel consumption, increasing pollution, and robbing the public of billions of hours of valuable time. In light of the present unsustainable conditions, we examine and analyze the concepts of mobility through an inquiry of time, space, human freedom, and social justice from an ethical and systemic viewpoint. We conclude that if hypermobility is not dealt with both as an individual and as a collective responsibility, the challenge to transport ethics and its systemicity could be further impaired.  相似文献

In this paper we study semiparametric estimators of the survival function and the cumulative hazard function based on left truncated and right censored data. Weak representations of the two estimators are derived, which are valid up to a given order statistic of the observations.  相似文献

This paper follows several case studies where the children’s services departments of English and Welsh local authorities have fundamentally redesigned the way they worked following the application of the Vanguard Method (Seddon, Systems thinking in the public sector, 2008), a particular form of systems thinking. After first studying the way the children’s social care service worked as a system, the social workers in these authorities were able to demonstrate the way that government-prescribed IT and performance measures were restricting the way they could do what was shown to matter to the children in their care. The paper will document how, after being granted ministerial permission to suspend the use of their old performance measures and IT, a new set of operating principles was developed and employed. The redesigned system has shown encouraging early results. Evidence from these case studies (following Yin 2009) is presented in the form of recorded operational improvements and statements from participants. The paper will be of topical relevance to all involved in social care in the light of the government-commissioned Munro Review (Munro, The Munro Review of child protection: final report, 2011). The issues discussed will also be germane to the many other public sector partner agencies involved in the delivery of social care services (e.g. police, health, housing associations).  相似文献

We explore problems involving the measurement of the performance of a system. We outline two systemic approaches that have come from different epistemological positions: one from the interpretivist paradigm (soft systems methodology) and the other from the cybernetic paradigm (viable systems model). These two systemic methodologies that have tackled problems involving performance measurement are considered and discussed: (a) Checkland’s systems ideas of ‘managing and controlling’ a system throughout a set of three measures of performance: efficacy, efficiency and effectiveness; and (b) Beer’s concepts of Actuality, Capability, Potentiality of the firm and his claims that the performance of a system needs to be quantifiable and resumed on ‘pure’ numbers which should reflect the survivability of the firm. A parallel is drawn between the two approaches concluding that although the paradigms underpinning them are in some way different, the practicalities of these approaches to control, measure and improve the performance of a system are very similar. A case involving the measurement of a proposed research strategic plan for a Manchester Metropolitan University Business School’s department is used to illustrate the systemic approaches.  相似文献

In contemplating better ways to manage, Stafford Beer says the big problem is that you are not determining absolute facts: you are establishing a set of conventions. Hence his view, that a model is neither true nor false: it is more or less useful. And while this paper suggests Beer’s Viable Systems Model (VSM) is overwhelmingly more, rather than less useful, that the VSM and its founding theories are virtually unknown at the level of everyday management begs the question, why? Over time we have learned about the usefulness of the VSM compared to other management theories, when used in the contest of the organisational strategic planning process. Thus through a sequence of diagrams based on Beer’s original drawings, we show how the VSM came to underpin a process for strategic planning in one organisation. The paper has three aims; to attach an everyday ‘common speak’ understanding to some of Beer’s work, to demonstrate how we have learned to appreciate the usefulness of the VSM and its associated diagrams and conventions and to suggest a link between the Action Research change methodology and Beer’s work.  相似文献

This paper describes work in progress which seeks to establish whether there are sufficient similarities between high-level teams operating in the business, government, and sporting environments to justify further research in these areas. It distinguishes strategic and tactical teams and identifies the characteristics of each within their separate disciplines. The paper concludes that there is indeed worthwhile research to be conducted in this field. Such research would not be confined to mere theory because the three areas investigated are already interconnected in a complex manner best investigated by a systemic approach.  相似文献

Gr?bner basis theory for parametric polynomial ideals is explored with the main objective of mimicking the Gr?bner basis theory for ideals. Given a parametric polynomial ideal, its basis is a comprehensive Gr?bner basis if and only if for every specialization of its parameters in a given field, the specialization of the basis is a Gr?bner basis of the associated specialized polynomial ideal.For various specializations of parameters, structure of specialized ideals becomes qualitatively different even though there are significant relationships as well because of finiteness properties. Key concepts foundational to Gr?bner basis theory are reexamined and/or further developed for the parametric case:(i) Definition of a comprehensive Gr?bner basis,(ii) test for a comprehensive Gr?bner basis,(iii) parameterized rewriting,(iv) S-polynomials among parametric polynomials,(v) completion algorithm for directly computing a comprehensive Gr?bner basis from a given basis of a parametric ideal. Elegant properties of Gr?bner bases in the classical ideal theory, such as for a fixed admissible term ordering,a unique Gr?bner basis can be associated with every polynomial ideal as well as that such a basis can be computed from any Gr?bner basis of an ideal, turn out to be a major challenge to generalize for parametric ideals; issues related to these investigations are explored. A prototype implementation of the algorithm has been successfully tried on many examples from the literature.  相似文献

Understanding the characteristics of the dynamic relationship between the onshore Renminbi (CNY) and the offshore Renminbi (CNH) exchange rates considering the impact of some extreme events is very important and it has wide implications in several areas such as hedging. For better estimating the dynamic relationship between CNY and CNH, the Granger-causality test and Bry-Boschan Business Cycle Dating Algorithm were employed in this paper. Due to the intrinsic complexity of the lead-lag relationships between CNY and CNH, the empirical mode decomposition (EMD) algorithm is used to decompose those time series data into several intrinsic mode function (IMF) components and a residual sequence, from high to low frequency. Based on the frequencies, the IMFs and a residual sequence are combined into three components, identified as short-term composition caused by some market activities, medium-term composition caused by some extreme events and the long-term trend. The empirical results indicate that when it only matters the short-term market activities, CNH always leads CNY; while the medium-term impact caused by those extreme events may alternate the lead-lag relationships between CNY and CNH.  相似文献
