Analysis of interactions among the barriers of reverse logistics   总被引:5,自引:0,他引:5  
The aim of this article is to analyze the interaction among the major barriers, which hinder or prevent the application of reverse logistics in automobile industries. A key task of top management is to diagnose those barriers of reverse logistics that could be crucial to the survival of the organization in the future. Existing models have focused on diagnosing these barriers independently. As a result, we lack a holistic view in understanding the barriers that hinder reverse logistics. This paper utilizes the Interpretive Structural Modeling (ISM) methodology to understand the mutual influences among the barriers so that those driving barriers, which can aggravate few more barriers and those independent barriers, which are most influenced by driving barriers are identified. By analyzing the barriers using this model, we may extract crucial barriers that hinder the reverse logistics activities. It can be observed that there are some barriers, which have both high driving power and dependency, thus needing more attention. An actual example of a small case automobile company provides some managerial insights into the methodology. Finally, the implications for practice and future research are discussed.  相似文献

The first part of this article shows that in actual practice technology assessment (TA) has clearly moved from its basic conception as a set of objective methodologies developed and used by experts, to a standpoint which increasingly recognizes the need to make room for public participation. This has led to a view of controversies as informal processes of TA. The second part of the article argues for a further step, namely to conceive of TA as a social proces taking place in a space largely defined by controversies. Correlatively, it provides some initial elements for an analytical understanding of controvtersies as the 'limiting factor' of TA.  相似文献

Technology assessment (TA) is team research that entails the cooperative effort of professionals from diverse disciplines. Whether this effort can be truly integrated into an interdisciplinary assessment is problematic, based on analyses of 24 actual TAs. To probe the situational and process factors that impinge on this interdisciplinary research process, we have performed laboratory simulations on TA-like problems. By controlling several key factors, these sessions have yielded insights into small group interactions and offer suggestive evidence for the conduct of future TAs. In these exercises the role of expertise was downplayed as groups preferred to operate in a “common-group learning” mode; epistemological differences emerged in the form of a “pecking order” favoring more quantitative sciences; and performing the leadership role reduced an individual's intellectual contribution to the problem-solving process. These exploratory TA simulations suggest merit in further efforts at controlled study of complex interdisciplinary processes.  相似文献

Technology Assessment (TA) has been a growing field of management study for the past four decades. An increasing number of studies have been carried out over the years contributing to the development of TA literature. Some of these studies summarized the history and growth of the field during its evolution. However, there has been no effort made to present an overview of the methods and tools that have been cited in TA literature. This paper attempts to fill that void. A thorough review of the TA articles published in leading journals in the management of technology field is conducted to identify the research methods or tools in those studies. The paper provides an introductory review of the use of technology assessment terminology during its development, which helps the readers avoid the confusion of the TA concept since its origination in public decision making forty years ago and where it is now — widely adopted in other sectors. A thorough presentation of the approaches, methods and tools that have been introduced or employed in both mainstream TA and “inverted TA” studies is then provided. The main content of the paper is related to the works published in leading international journals that involve certain research methods or techniques.  相似文献

A systematic two-component approach (front-end component, back-end component) to bridging unconnected disciplines and accelerating potentially radical discovery and innovation (based wholly or partially on text mining procedures) is presented. The front-end component has similar objectives to those in the classical literature-based discovery (LBD) approach, although it is different mechanistically and operationally. The front-end component will systematically identify technical disciplines (and their associated leading experts) that are directly or indirectly-related to solving technical problems of high interest. The back-end component is actually a family of back-end techniques, only one of which shares the strictly literature-based analysis of the classical LBD approach. The non-LBD back-end techniques (literature-assisted discovery) make use of the human experts associated with the disparate literatures (disciplines) uncovered in the front-end to generate radical discovery and innovation.Specifically, in the literature-assisted discovery operational mode, these disparate discipline experts could be used as:
1. Recipients of solicitation announcements (BAA, SBIR, MURI, journal Special Issue calls for papers, etc.),
2. Participants in Workshops, Advisory Panels, Review Panels, Roadmaps, and War Games,
3. Points of Contact for Field Science Advisors, Foreign Field Offices, Program Officer site visits, and potential transitions.

Economic growth has increased the potential for a materially more fulfilling life. But economic growth has a price: it undermines the contributions of households, communities, and nature, on which all economic activity depends. How can we make visible, in economic terms, the qualities that are lost as a consequence of excessive economic activity? In the spirit of these critical discussions, Feminist Economics has initiated this issue's exploration of quality of life: Which aspects of life do economists regard as essential to the concept? What can we learn from disciplines whose traditions of quality of life research are older than ours? The ten articles that follow suggest, in the brief form allowed by the format, a number of different ways to approach these questions.  相似文献

Political entrepreneurship and bidding for political monopoly   总被引:2,自引:0,他引:2  
An analytical framework for dealing with political entrepreneurship and reform is proposed which is based on some new combinations of Schumpeterian political economy, an extended version of Tullock's model of democracy as franchise-bidding for natural monopoly and some basic elements of New Institutional Economics. It is shown that problems of insufficient award criteria and incomplete contracts which may arise in economic bidding schemes, also – and even more so – characterise political competition. At the same time, these conditions create leeway for Schumpeterian political entrepreneurship. The same is true for various barriers to entry in politics. These barriers affect a trade-off between political stability and political contestability which will be discussed with special emphasis on incentives and opportunities for political entrepreneurship in the sense of risking long-term investments in basic political reforms.  相似文献

This paper provides an analytical framework to evaluate under what conditions the natural resource production could promote or hinder urbanization process, focusing on factors mostly relevant for China. Considering both structure breaks and cross-sectional dependence as well as spatial spillovers, the study deploys a comprehensive approach to rigorously prove the validity of the proposed space–time panel data model that includes the second generation panel unit root test and panel cointegration, panel threshold regression and spatial panel Durbin model. The results not only offer strong evidences that the natural resource production non-linearly impacts on urbanization process, but also show that there exists a dynamic response over time and space as well as space–time diffusion impact, in which these percentages are different from each other confirming an asymmetric effect of the natural resource production on urbanization process.  相似文献

The literature on open innovation (OI) is characterised by studies based both on large companies and small and medium-sized enterprises (SMEs). Among all, one of the less explored issues in SMEs is what impedes them to adopt OI. Thus, this paper has the threefold objective to identify which factors hinder the adoption of OI in SMEs, to investigate if different behaviours exist among SMEs in relation to these factors, and to understand if the same factors effectively influence the level of adoption of OI. Based on a survey on 157 Italian SMEs, we identified four main barriers (namely, ‘knowledge’, ‘collaboration’, ‘organisational’, and ‘financial and strategic’) and three profiles of firms, different in terms of innovativeness of the industries they belong to (knowledge intensive, medium-innovative, and less innovative) and hampering factors perceived (‘knowledge’, ‘financial and strategic’, and ‘collaboration’ and ‘organisational’ barriers). Moreover, we found that some of these factors effectively impede the adoption of the paradigm.  相似文献

This paper analyses, from an institutionalist perspective, the emergence, nature and ways in which parliamentary scientific and technological advice activities are carried out in different European countries. A diffusion process from the United Sates could be identified in the early times, but some local preconditions are also important for the adoption of these practices in Europe, as well as the existence of some political entrepreneurs willing to advance the initiatives within their respective political systems. We argue that the connection of technology assessment (TA) with the political process can only be understood if the former is regarded not only as an input in the decision-making process but also as a legitimising mechanism.Different models of arrangements of parliamentary TA (PTA) are identified, depending on the degree of inclusiveness of different actors in the TA process. The adaptation, consolidation and differential impact of these organizations are mediated by two factors: the capacity of PTA organizations to gain support, both inside and outside the Legislature, and their capacity to access decision makers in an environment of competition with other organizations that also produce TA. Models of PTA have both types of these capacities in differing degrees. It is argued that differences in the potential impact of TA activities in the different countries are to be analysed in the context of the rules of the political game and the types of incentives that TA organizations face. The degree of autonomy/dependence and exclusivity/nonexclusivity of the assessment for the parliaments are essential for understanding the diversity of impacts.  相似文献

A system for the analysis and planning of new ventures is developed which provides a structure for the application of logical, mathematical, and scientific procedures to decision problems which (1) involve a significant portion of an organization's resources, (2) have long term effects on a firm's future success, and (3) are characterized by uncertainty in many of the factors important to the decision. The system is based on a synthesis of various analytical techniques from the fields of technological forecasting, decision analysis, and system dynamics, and provides a general methodology for rank-ordering new venture candidates and determining the resource allocation level required for new venture portfolios designed to achieve long term growth objectives. The role played by technological forecasting in new venture planning and in the selection of engineering projects is discussed.  相似文献

Through the use of survey data from the West Bank, this paper explores the effects of the Apartheid/Separation Wall in the occupied territory of the West Bank on Palestinian society. How has the Wall separated a population from their loved ones, their orchards and crops, homes, and overall livelihood? How have these relationships transformed? Place and space have special meanings in Palestinian experience and consciousness, and yet Palestinians remain vulnerable to punishment through control of access to spaces and places.

The inability to reach one’s home or land has serious ramifications on the psyche of individuals and communities. Not only do physical barriers hinder social interactions, but they also impact society in numerous ways. The effects on Palestinian society are largely invisible and have long-term and far-reaching consequences. These consequences run deeper than the physical barriers that have created them.

Social continuity has repeatedly been disrupted due to the geopolitical transformation of land control and roads network, which favours one group (Israeli Jews) over another (Palestinian Arabs—Christian and Muslim). The policies of separation, through the wall, checkpoints, and the permit regime, have actually separated Palestinians from other Palestinians, and not Palestinians from Israelis.  相似文献

In recent years there have been a number of attempts to develop a more comprehensive approach to the issue of measuring resource use and/or pollution generation embodied in trade flows, including contributions that combine input-output techniques and Ecological Footprint analysis. In this two-part paper we describe how to enumerate the resource and/or pollution content of inter-regional and inter-national trade flows (Part 1) and we present a literature review of recent methodological and empirical developments (Part 2). It is straightforward in principle to extend the basic input-output approach to capture international trade flows. However, in practice, problems of data availability and compatibility, and of computability of extended input-output matrices, mean that simplifying assumptions are generally applied, but with the implications of these assumptions often not made fully explicit. What appears to be absent from previous applications is an account of the analytical method by which Ecological Footprints should ideally be estimated in an international input-output accounting analysis. This allows an explicit analysis of the problems that prevent the application of the full method and identification of the most appropriate short-cut methods in a transparent way. The objective of this paper is to provide such an account.  相似文献

Fuel cell technologies have long been recognized as one of the most promising future energy solutions. Nevertheless, major technological barriers hinder the potential realization of this clean energy source. Citation network analysis methodology is used here to identify major research trends, critical technological issues, and proposed resolutions to raise the effectiveness of investment of R&D resources in fuel cell technology development.The main path analyses identify two research streams for the Proton-Exchange Membrane Fuel Cell (PEMFC) and Direct Methanol Fuel Cell (DMFC) technologies. Analyses of cited publications show that most of the technological barriers for PEMFC have been addressed and that performance has reached an acceptable level. On the other hand, DMFC still suffers from methanol and water crossover problems. Multiple main path analysis identifies specific research groups working on technological problems in DMFC. The Direct Formic Acid Fuel Cell (DFAFC) and Direct Ethanol Fuel Cell (DEFC) have recently emerged to address the toxicity of methanol, while DMFC performance is being enhanced through research on porous carbon plates, water transportation, and methanol concentrations, and the research group at Micro DMFC is applying fuel cells in electronics devices. Despite considerable research on Solid Oxide Fuel Cell (SOFC), its research stream does not appear in the main paths, most likely because of a broad divergence in research subjects. Growth curve analysis forecasts that fuel cell research is in the growth stage and will enter maturity in 2018. Although emerging technologies show advantages in performance and cost, the findings presented here can raise the effectiveness of critical research project selection, thus increasing the likelihood of success.  相似文献

Antonelli, over a hundred years ago, pioneered techniques of economic analysis which still can be usefully employed to provide apparently new insights in duality theory. This assertion is demonstrated through the applications of these techniques to derive specific results in duality theory. These applications allow an apparently new derivation of the equality between the partial derivative of the expenditure function, with respect to the price of some good, and the compensated level of demand for this good. In addition, use of Antonelli's analytical techniques reveals links between certain results in duality theory that, apparently, have not been noticed before in the relevant literature.  相似文献

Social phenomena can be described and explained through different levels of analysis, which correspond to the theoretical and methodological domains of different disciplines. According to a hierarchy of disciplines which moves from high-order to low-order levels, collective phenomena should be grounded on individual mental processes which, in turn, should rely on brain processes. The crucial question is whether the neuroscientific account of brain processes can be conceived as equivalent to the psychological account of mental processes. It is argued against the complete equivalence of the two kinds of accounts. However, it is maintained that a specific contribution can derive from each discipline so to provide an advance in understanding. It is questioned which could be the better way for psychology and neuroscience to inform each other. It is suggested that knowledge coming from the two disciplines, rather than being simply juxtaposed, should be integrated so to allow each discipline to give and receive insight to/from the other one.  相似文献

This paper integrates the analytic hierarchy process (AHP) with scenario analysis techniques to explore the commercialization of future hydrogen fuel processor technologies. AHP is a multi-attribute decision analysis tool useful for evaluating decisions with multiple criteria and alternatives. In this paper, AHP is extended using a technique called perspective-based scenario analysis (PBSA). In PBSA, scenario analysis is conducted based on potential future decision-maker perspectives that are integrated into the AHP framework. This paper discusses this method and applies it to the evaluation of hydrogen fuel processor technologies 15–20 years hence. The results provide an added layer of insight into the opportunities and barriers for the commercialization of these technologies as well as the methodological opportunities for using AHP and PBSA as a futures tool.  相似文献
