Prediction of natural disasters and their consequences is difficult due to the uncertainties and complexity of multiple related factors. This article explores the use of domain knowledge and spatial data to construct a Bayesian network (BN) that facilitates the integration of multiple factors and quantification of uncertainties within a consistent system for assessment of catastrophic risk. A BN is chosen due to its advantages such as merging multiple source data and domain knowledge in a consistent system, learning from the data set, inference with missing data, and support of decision making. A key advantage of our methodology is the combination of domain knowledge and learning from the data to construct a robust network. To improve the assessment, we employ spatial data analysis and data mining to extend the training data set, select risk factors, and fine‐tune the network. Another major advantage of our methodology is the integration of an optimal discretizer, informative feature selector, learners, search strategies for local topologies, and Bayesian model averaging. These techniques all contribute to a robust prediction of risk probability of natural disasters. In the flood disaster's study, our methodology achieved a better probability of detection of high risk, a better precision, and a better ROC area compared with other methods, using both cross‐validation and prediction of catastrophic risk based on historic data. Our results suggest that BN is a good alternative for risk assessment and as a decision tool in the management of catastrophic risk.  相似文献

This paper examines response rates (RR) in published research in business and management journals. Its aim is to evaluate the efficacy of RR‐enhancing strategies, explore differences in RR between sub‐disciplines and geographical regions, provide a critical appraisal of RR in business and management research, and offer guidelines for assessing and improving RR in business and management research. Data are analysed from 1093 survey‐based papers published between 2009 and 2013 in a representative sample of business and management journals. The results of the study are discussed, and their implications for RR in business and management research are provided.  相似文献

Big data and analytics (BDA) are gaining momentum, particularly in the practitioner world. Research linking BDA to improved organizational performance seems scarce and widely dispersed though, with the majority focused on specific domains and/or macro‐level relationships. In order to synthesize past research and advance knowledge of the potential organizational value of BDA, the authors obtained a data set of 327 primary studies and 1252 secondary cited papers. This paper reviews this body of research, using three bibliometric methods. First, it elucidates its intellectual foundations via co‐citation analysis. Second, it visualizes the historical evolution of BDA and performance research and its substreams through algorithmic historiography. Third, it provides insights into the field's potential evolution via bibliographic coupling. The results reveal that the academic attention for the BDA–performance link has been increasing rapidly. The study uncovered ten research clusters that form the field's foundation. While research seems to have evolved following two main, isolated streams, the past decade has witnessed more cross‐disciplinary collaborations. Moreover, the study identified several research topics undergoing focused development, including financial and customer risk management, text mining and evolutionary algorithms. The review concludes with a discussion of the implications for different functional management domains and the gaps for both research and practice.  相似文献

A challenge with multiple chemical risk assessment is the need to consider the joint behavior of chemicals in mixtures. To address this need, pharmacologists and toxicologists have developed methods over the years to evaluate and test chemical interaction. In practice, however, testing of chemical interaction more often comprises ad hoc binary combinations and rarely examines higher order combinations. One explanation for this practice is the belief that there are simply too many possible combinations of chemicals to consider. Indeed, under stochastic conditions the possible number of chemical combinations scales geometrically as the pool of chemicals increases. However, the occurrence of chemicals in the environment is determined by factors, economic in part, which favor some chemicals over others. We investigate methods from the field of biogeography, originally developed to study avian species co‐occurrence patterns, and adapt these approaches to examine chemical co‐occurrence. These methods were applied to a national survey of pesticide residues in 168 child care centers from across the country. Our findings show that pesticide co‐occurrence in the child care center was not random but highly structured, leading to the co‐occurrence of specific pesticide combinations. Thus, ecological studies of species co‐occurrence parallel the issue of chemical co‐occurrence at specific locations. Both are driven by processes that introduce structure in the pattern of co‐occurrence. We conclude that the biogeographical tools used to determine when this structure occurs in ecological studies are relevant to evaluations of pesticide mixtures for exposure and risk assessment.  相似文献

For nearly two decades, electronic data interchange (EDI) has been widely viewed as a technology pivotal to supply chain management that has also provided benefits to firms on multiple levels. Despite a substantial body of literature, there are a number of conflicting and inconclusive research results in this field. In this study, we synthesize the diverse body of research in EDI by organizing the literature into an initial theoretical framework. Based on a meta‐analysis of results from the empirical literature, we seek to clarify conflicting results from the literature in order to develop a more unified theoretical framework of contextual variables associated with EDI adoption factors and outcomes. From a managerial standpoint, our literature‐based framework offers a set of guidelines for making successful EDI adoption and implementation decisions.  相似文献

Mirroring the growing trend for firms to support their operations by locating activities abroad, research on the practice of offshoring has increased considerably in recent years. However, despite the mounting research, understanding of the key factors influencing decision‐making for offshoring remains surprisingly limited due to fragmentation. In this study, we synthesize and integrate insights from different research domains in order to develop a comprehensive decisional framework for key offshoring decisions. The integrative decisional framework is based on a systematic review of offshoring research published in the most influential management and business journals in the past 25 years. In addition to providing a snapshot of the state of research on decision‐making for offshoring, this study aims to stimulate future research by identifying promising research opportunities. In particular, we propose that future research should use alternative theories to incorporate overlooked aspects of decision‐making, integrate different theories to account for the interdependencies between decisions, and adopt a portfolio perspective that considers each decision as part of an overall offshoring strategy.  相似文献

Over the past two decades, scholarly interest in employer branding has strongly increased. Simultaneously, however, employer branding research has developed into a fragmented field with heterogeneous interpretations of the employer branding concept and its scope, which has impeded further theoretical and empirical advancement. To strengthen the foundation for future work, this paper takes a brand equity perspective to review the extant literature and create an integrative model of employer branding. Using an analytical approach, the authors identify 187 articles, which they integrate along different employer brand dimensions and branding strategies: (i) conceptual; (ii) employer knowledge dimensions; (iii) employer branding activities and strategies. On the basis of this review, the authors develop an employer branding value chain model and derive future research avenues as well as practical implications.  相似文献

The present review is an investigation of the ways in which interorganizational networks coordinate their activities for the benefit of all parties. In this context ‘interorganizational networks’ consist of three or more separate, collaborating entities, and the question of their leadership has been well researched in a number of disciplines. Its interest to economic actors is growing. However, the findings of studies that have focused on leadership in such networks are somewhat incoherent. As demonstrated in the present review, this incoherence largely results from the consideration of different forms of network (e.g. hierarchical vs heterarchical), levels of analysis (e.g. organizational vs network), and terms used to describe the phenomena (e.g. governance or orchestration, quite apart from leadership). Against this background, the present review contributes to the body of knowledge on this topic in two main areas. First, the literature is reviewed in order to provide an overview of the key characteristics of forms of network and levels of analysis. Moreover, the view that leadership in such networks influences all members in order to ‘make things happen’ is suggested. Secondly, future avenues of research are identified in order to stimulate progress in this important area of study.  相似文献

Through a systematic review of 118 peer‐reviewed journal articles published between 1961 and 2017, this article provides an integrative picture of the state of the art of the family firm innovation literature. Our aim is to widen existing understanding of innovation in family firms by building a theoretical bridge with studies in the mainstream innovation literature. Specifically, in identifying the main gaps in the literature and providing future research directions, our critical and dynamic picture of family‐specific determinants of innovation is intended to advance the debate on innovation in general, and family firms in particular.  相似文献

The incorporation of human experience data (HD) into the risk assessment process is encouraged by various authorities with the aim of improving the robustness of the subsequent findings. HD, however, can present in many forms, ranging from epidemiological studies to the accumulated experiences from poison centers. This diversity of the human experience, combined with the manner in which it may (or may not) present, creates several challenges for risk assessors if they are to give available HD due weight in the RA process. An evaluation was made of how HD has been cited and used within the 64 human health RAs published by the EU to the end of 2005. In all RAs, HD had been cited to some degree. But there was no consistency between how cited data had subsequently been taken forward and used in the evaluation of different endpoints, either between the RAs authored by the same or different EU Member States. The lack of any accepted guidance for addressing the role that HD can play within the RA process appears to lead to this situation. Recommendations are provided on the scope and focus such guidance could usefully be expected to take.  相似文献

The use of surrogate species is an important tool in predicting the effects of management decisions or the establishment of protective measures for endangered/threatened species. While relying on a handful of model species to predict the fate of scores of distantly related target species has been criticized, a quantitative measure linking life history traits and population predictions has been sorely missing. We derive here a closed‐form expression aimed at determining conditions under which sublethal effects of a toxicant on surrogate species population outcomes will reliably predict outcomes of target (listed) species. We develop a critical threshold in fecundity reduction above which the surrogate species outcomes indicate positive population growth, while the listed species is driven to extinction. Thus we have established a means of determining conditions under which we are prone to making a “Type II” error in assessing ecological risk using surrogate species. Finally, we use the derived expression and life history data to compare outcomes from four different commonly used fish surrogate species (round goby, fathead minnow, smallmouth bass, cutthroat trout) and their target listed species (Chinook and Coho salmon). We illustrate that all four surrogate species fail to predict population outcomes for the listed species in cases of as little as 15% fecundity reduction due to toxicant exposure. Furthermore, surrogate species reliability is a function of toxicant level, so that some species are reliable at some levels but not at others. We discuss the implications of these findings, and outline further analyses that occur as a natural extension of the criteria developed here.  相似文献

Collaborative innovation with customers or users is increasingly important for the development of new products and services. In this paper we provide a review of the literature, placing emphasis on how firms engage in collaborative innovation with individual and business customers. Our review develops a synthesized conceptual framework from three existing models, and other streams of research, to organize this diverse body of literature. We review studies from several disciplines including innovation, strategy, management, marketing and information technology. Although much of the literature assumes net positive benefits from such collaboration, we also discuss contrary perspectives. We highlight areas in which research is needed for greater understanding of the strategic issues and for managing the collaborative process, and provide suggestions for future studies.  相似文献

A life-cycle approach takes a cradle-to-grave perspective of a product's numerous activities from the raw material extraction to final disposal. There have been recent efforts to develop life-cycle assessment (LCA) to assess both environmental and human health issues. The question then arises: what are the capabilities of LCA, especially in relation to risk assessment? To address this question, this paper first describes the LCA mass-based accounting system and then analyzes the use of this approach for environmental and human health assessment. The key LCA limitations in this respect are loss of spatial, temporal, dose-response, and threshold information. These limitations affect LCA's capability to assess several environmental issues, and human health in particular. This leads to the conclusion that LCA impact assessment does not predict or measure actual effects, quantitate risks, or address safety. Instead, LCA uses mass loadings with simplifying assumptions and subjective judgments to add independent effects and exposures into an overall score. As a result, LCA identifies possible human health issues on a systemwide basis from a worst case, hypothetical hazard perspective. Ideally, the identified issues would then be addressed by more detailed assessment methods, such as risk assessment.  相似文献

A transfer price is a value placed on the goods or services which are traded between divisions of an organization. This paper attempts to make the subject of transfer pricing accessible to researchers and others interested in managerial problems so that a very real managerial problem can be studied in a broader managerial context. The not insubstantial literature that has grown up in the transfer pricing area is reviewed and, in particular, a critical evaluation of recent writings in the field is provided. It is shown that little which is unequivocal is known about transfer pricing and that the choices made by managers with regard to transfer pricing are little understood, both with regard to the factors which drive choice and the differences between choice in practice and theoretical interpretations. It is suggested that progress in the area will require a richer understanding of the realities confronting practising managers. Research by means of field studies, particularly case studies, is recommended to provide this. A series of hypotheses and issues, representing the dilemmas facing managers, is provided as a theoretical grounding for such research.  相似文献

Over the last three decades, customer experience (CE) has developed from a burgeoning concept to a widely recognized phenomenon in terms of both research and practice. To account for the complexity of consumption decisions, the CE literature encompasses both the rational information processing approach to consumer decision‐making and the experiential approach, which includes emotions, feelings and sub‐consciousness. The authors classify and examine CE research on two levels. Studies on static CE analyze experiences during touchpoints at one point in time, while studies on dynamic CE assess how experiences evolve over time. Furthermore, both static and dynamic CE research take place from two distinct theoretical perspectives: the organization and the consumer. As both theoretical perspectives essentially deal with the same phenomenon – the organizational perspective with the creation of CEs and the consumer perspective with the perception of customer experiences – there is potential for a productive symbiosis between them. The authors propose that connecting insights from both perspectives can contribute to a better understanding of what constitutes a CE for consumers and how firms can effectively manage it. First, the authors discuss the development of CE and argue that it has evolved into a broad and fragmented ‘umbrella construct’. Second, after distinguishing and defining static and dynamic CE, they systematically evaluate the state of knowledge in both the organizational and consumer perspectives. Finally, they develop an agenda for future research that integrates the consumer perspective into organizational CE research.  相似文献
