What does theory predict about the way government size and structure adapts to changes in government’s organisational environment (particularly to uncertainty and complexity)? In this paper, we review the theory and evidence from the literature about the way government size adjusts to such changes -- particularly to changes in macroeconomic fundamentals like gross national product (GDP). We find that the traditional theories from the organisational theory literature—like the contingency-based view, resource-based view and the rational choice view -- fail to provide global explanations for much of the variation we see in the world around us. Instead, theorists need to adopt a “mosaic view” of organisational theory -- accepting that different theories may explain the way public sector size and structure responds to the uncertainty and variability in its (macroeconomic) organisational environment. We also provide several empirical hypotheses to test such a mosaic-view.  相似文献

Risk analysis for biological invasions is similar to other types of natural and human hazards. For example, risk analysis for chemical spills requires the evaluation of basic information on where a spill occurs; exposure level and toxicity of the chemical agent; knowledge of the physical processes involved in its rate and direction of spread; and potential impacts to the environment, economy, and human health relative to containment costs. Unlike typical chemical spills, biological invasions can have long lag times from introduction and establishment to successful invasion, they reproduce, and they can spread rapidly by physical and biological processes. We use a risk analysis framework to suggest a general strategy for risk analysis for invasive species and invaded habitats. It requires: (1) problem formation (scoping the problem, defining assessment endpoints); (2) analysis (information on species traits, matching species traits to suitable habitats, estimating exposure, surveys of current distribution and abundance); (3) risk characterization (understanding of data completeness, estimates of the "potential" distribution and abundance; estimates of the potential rate of spread; and probable risks, impacts, and costs); and (4) risk management (containment potential, costs, and opportunity costs; legal mandates and social considerations and information science and technology needs).  相似文献

The reduction or the complete elimination of specific types of weapons, particularly the elimination of all weapons of mass destruction, is one of the most important challenges that the international community should face in the 21th century. In this paper, a group of proposals on the possible roles to be played by the International Atomic Energy Agency (IAEA), the Organisation for the Prohibition of Chemical Weapons (OPCW), the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) and the Conference on Disarmament (CD) is included.  相似文献

Design rework is a core phenomenon in new product development (NPD). Yet carrying out design rework presupposes recognizing the need for it. I characterize the types of interpersonal knowledge transfer that help developers realize the need for design rework in NPD. As predicted by the NPD literature, I find that individuals who interact frequently with colleagues to address their task interdependences are more likely to realize the need for rework. I also learn that interacting with colleagues who have different expertise in process‐related knowledge (as opposed to product‐related knowledge) facilitates realizing the need for rework. However, to develop a deeper understanding of how individuals recognize the need for rework when interacting with others, we must expand our views beyond task interdependence and expertise‐related factors. In particular, organizational variables—both formal and informal—play a significant role. With respect to formal hierarchical structures, actors of superior rank are less likely to realize the need for rework regardless of whether or not their interacting partner is of superior rank; however, actors of superior rank are more likely to trigger realizing the need for rework when interacting with partners of subordinate rank. By examining an organization's informal structure, I discover that the social “embeddedness” of developers (i.e., the energy and attention invested in a dyadic relationship) significantly influences their propensity to realize the need for rework. Several hypotheses are tested in a sociometric study conducted within the development department of a software company, and I discuss the implications for behavioral operations in NPD.  相似文献

In this article, Andrea Caruso makes it clear that EUTELSAT, the European Telecommunications Satellite Organisation, is a working model of a Single European Market in the field of providing and operating communications satellites for public telecommunications in all EEC and some non-EEC Member States. EUTELSAT is transnational and based on co-operation and exchange.This regional telecommunications system achieves considerable economies of scale compared with any national one, as well as technological and commercial benefits like VSAT (Very Small Aperture Terminal) services for the business user, and the ability of in-orbit satellites to be very flexible in terms of ground coverage zones on the Continent.‘1992’ requires greater inter-country communication and the EUTELSAT network is already in place in Europe to supply it.  相似文献

Criteria are proposed for both an acceptable upper bound of nuclear power plant risk and a lower bound as a design target. Recognizing that the public risk associated with a power plant can be estimated only by probabilistic analysis of the design features, the spread between the lower design target and the upper bound provides a margin for uncertainty in th probabilistic estimate. The combination of a low probabilistic design target and this margin provides a reasonable expectation that the overall performance will be in the domain of an acceptable risk level. Because the exposure to potential risk is chiefly in the locality of the nuclear station, it is also proposed that compensatory benefits should be provided locally and that these be included as a cost of operation. It is suggested that the upper bound be set at a risk level equivalent to those risks of routine living which are normally accepted, i.e., about 10-4 deaths per year per person (100 deaths/yr/million). The proposed lower design target is 10-8 (0.1 deaths/yr/million), about one-hundredth of the minimal risk from the natural hazards all people are exposed to.  相似文献

Roberts, McNulty and Stiles (2005) focus on the attitudes and behaviours of non-executive directors in their recommendations for improving board effectiveness. This paper addresses the importance of providing incentives for non-executives in order to improve board effectiveness. It first points out that the current norms and practices in corporate governance suggest that, without strong incentives, non-executive directors are unlikely to become engaged in corporate governance, to challenge executive decision, and to remain independent of executive influences. It then proposes that, for non-executive directors to develop the attitudes and behaviors recommended by Roberts, McNulty and Stiles, it is important to require them own a significant amount of company stocks over a long period of time. It also addresses some concerns regarding the use of stock ownership to improve the effectiveness of non-executive directors in corporate governance.  相似文献

Strategic management scholars have long emphasized the importance of innovation for a firm's competitive advantage and performance. However, the current state of knowledge about the strategic management of innovation is characterized by conflicting theoretical predictions, persisting knowledge gaps and theoretical inconsistencies. Adopting a ‘systematic’ approach to reviewing the literature, this paper combines different quantitative methods – co‐word analysis, cluster analysis and frequency analysis – to review 342 articles on the strategic management of innovation published in seven journals from 1992 to 2010. On the basis of these analyses, suggestions are developed for future research which could help to promote future theory development and provide relevant material for policy decisions that managers and executives have to make when they manage innovation.  相似文献

In any crisis, there is a great deal of uncertainty, often geographical uncertainty or, more precisely, spatiotemporal uncertainty. Examples include the spread of contamination from an industrial accident, drifting volcanic ash, and the path of a hurricane. Estimating spatiotemporal probabilities is usually a difficult task, but that is not our primary concern. Rather, we ask how analysts can communicate spatiotemporal uncertainty to those handling the crisis. We comment on the somewhat limited literature on the representation of spatial uncertainty on maps. We note that many cognitive issues arise and that the potential for confusion is high. We note that in the early stages of handling a crisis, the uncertainties involved may be deep, i.e., difficult or impossible to quantify in the time available. In such circumstance, we suggest the idea of presenting multiple scenarios.  相似文献

Microbial food safety has been the focus of research across various disciplines within the risk analysis community. Natural scientists involved in food microbiology and related disciplines work on the identification of health hazards, and the detection of pathogenic microorganisms. To perform risk assessment, research activities are increasingly focused on the quantification of microbial contamination of food products at various stages in the food chain, and modeling the impact of this contamination on human health. Social scientists conduct research into how consumers perceive food risks, and how best to develop effective risk communication with consumers in order to improve public health through improved food handling practices. The two approaches converge at the end of the food chain, where the activities regarding food preparation and food consumption are considered. Both natural and social sciences may benefit from input and expertise from the perspective of the alternative discipline, although, to date, the integration of social and natural sciences has been somewhat limited. This article therefore explores the potential of a transdisciplinary approach to food risk analysis in terms of delivering additional improvements to public health. Developing knowledge arising from research in both the natural and social sciences, we present a novel framework involving the integration of the two approaches that might provide the most effective way to improve the consumer health associated with food-borne illness.  相似文献

In this editorial, the co‐editors‐in‐chief undertake a number of tasks related to International Journal of Management Reviews (IJMR). They begin by reviewing the objectives set out by Macpherson and Jones in their 2010 editorial (IJMR, 12, pp. 107–113). The benefits of publishing in IJMR for scholars at various stages of their careers are then discussed. The section outlining the progress of IJMR over the last four years sets out the main reasons why so many papers are desk rejected by the co‐editors. The main criteria for writing an analytical literature review of the type that the editors aspire to publish in the Journal are then discussed. The objectives are not simply to reduce the number of desk rejects, but also to encourage authors to be more ambitious and innovative in their approaches to reviews of the literature.  相似文献

Novotel is one of the world's major hotel chains, occupying a leading place in Europe and with locations globally. We interpret Novotel's change management programme in the 1990s in three parts. First, we summarise the actions that managers took in terms of strategy and organisation. Second, we consider the sequence and timing of events, and how this resulted in rapid transformation in an organisation employing more than 30,000 people. Third, we emphasise the dialectical nature of the change processes: an element often ignored in the literature that likes to see things as an either–or rather than a both. We observed both deliberation and experimentation; both integration and differentiation. We also observed both preservation and transformation, as noted in our sub-title ‘Back to the Future’. Finally, we wrap up with a discussion explaining how our story can add to better thinking about change. We suggest that we can shed new light on some old debates and provide tangible guides for action.  相似文献

It is common perspective in risk analysis that there are two kinds of uncertainties: i) variability as resulting from heterogeneity and stochasticity (aleatory uncertainty) and ii) partial ignorance or epistemic uncertainties resulting from systematic measurement error and lack of knowledge. Probability theory is recognized as the proper tool for treating the aleatory uncertainties, but there are different views on what is the best approach for describing partial ignorance and epistemic uncertainties. Subjective probabilities are often used for representing this type of ignorance and uncertainties, but several alternative approaches have been suggested, including interval analysis, probability bound analysis, and bounds based on evidence theory. It is argued that probability theory generates too precise results when the background knowledge of the probabilities is poor. In this article, we look more closely into this issue. We argue that this critique of probability theory is based on a conception of risk assessment being a tool to objectively report on the true risk and variabilities. If risk assessment is seen instead as a method for describing the analysts’ (and possibly other stakeholders’) uncertainties about unknown quantities, the alternative approaches (such as the interval analysis) often fail in providing the necessary decision support.  相似文献

The European Commission has proposed a radical new policy for the regulation of chemicals in the EU in the form of a White Paper. The current system has separate regulatory provisions for "new" chemicals (introduced to the market since September 18, 1981) and "existing" chemicals (on the market before September 18,1981). The proposed future policy will have a single unified regulatory system for all chemicals, which should result in better regulation of chemicals in the EU single market. It will be better because risk assessments will be targeted at the chemicals of greatest concern. Furthermore, the system will be streamlined, making regulatory decisions faster, and thus reducing the so-called burden of the past (the large number of chemicals that have never been assessed for their risks to human health or the environment). The new system incorporates the precautionary principle, which will be applied where there is an early indication of unacceptable risk or where there is undue delay in the regulatory process. Moreover, the new strategy is intended to promote greater transparency for all stakeholders.  相似文献

International business scholars are increasingly focusing on the unique advantages of being foreign, or assets of foreignness (AOFs). Although scholars have identified a broad range of AOFs, it is unclear why they exist. In this paper, we bring together extant yet disparate literature and integrate insights from the institution-based view, resource-based theory, and transaction cost economics to advance theory of the underlying sources and workings of AOFs. In doing so, we elucidate the conceptual underpinnings of AOFs as well as their relation to multinational enterprise (MNE) success, complementing scholarship regarding the liability of foreignness. Critically, we also distinguish AOFs from related concepts, such as ownership advantages, explaining how and why they differ conceptually. We put forth several testable propositions that stem from our synthesis of theory in this research stream, bolstering the conceptual foundations of the drivers, dynamics, and longevity of AOFs. Finally, we draw attention to under-researched aspects of AOFs, thereby propelling a theory-based agenda for future research on AOFs and, consequently, MNE success.  相似文献

The article argues that there is a need for a new theory of production economics. The premise is that the only extant theory of production in orthodox discourse depends on the maximising model of human behaviour. Adam Smith's bifurcation of economic theory into the province of self-interest and that of justice also blocked off the potential for germinating a theory of production that would draw on motives other than self-interest. The foundations for such an approach have already been set out by Bray in a neglected study. He suggested that mathematical economics was held back, rather than advanced, by its bondage to static equilibrium analysis.  相似文献
