Environmental scanning is a broadly defined concept, having first received attention from scholars in the late 1960s. Over the years a number of similar and overlapping constructs have emerged in management literature. The aim of this study, via a systematic review and thematic analysis of relevant empirical research, is to consolidate foundation environmental scanning knowledge, demonstrate how scanning research has developed and fragmented over time, and propose an agenda for future research. The first contribution of our review is a new typology of environmental scanning research made up of five discrete research views, which provides a more comprehensive and contemporary overview of the field than previous studies. The second is a proposed agenda for future research that explicitly acknowledges the role of technology, an area that is presently underdeveloped in foundation scanning literature. The third contribution is to signpost future directions for research on scanning and organisational performance using a number of theoretical perspectives. The overall outcome of our review is to move scanning research on from increasingly incremental contributions concerned with context to a place where the changing role of technology and the mechanisms through which environmental scanning contributes to competitive advantage can be more thoroughly understood. 相似文献

David F. Robinson 《Long Range Planning》1974,7(1):58-60
Human Asset Accounting (‘HAA’) is not an accepted tool of long range planning. Indeed many planners probably look sceptically on the possibility that it will ever become a technique which is important to them in their work. Unlike many other methods which have been successfully developed over the last few years HAA involves concepts which are so new that as yet relatively few people have come into contact with them. The object of this article is to give some indication of the conceptual framework on which HAA theories are based and to describe one of the techniques which is being evolved as a possible management and planning tool. 相似文献

In recent years social policy in relation to lone parents has placed heavy emphasis on increasing the participation of this group in the labour market. If anything, the newly elected Labour government appears to be more committed to this objective than its predecessor. This paper details some of the findings from a focus-groups exercise with lone mothers in Belfast conducted in 1995. The data underline the limitations of many aspects of the measures taken to encourage lone parents to work and raise questions about the appropriateness of current policy. 相似文献

Traditional approaches for modeling economic production lot‐sizing problems assume that a single, fixed equipment setup cost is incurred each time a product is run, regardless of the quantity manufactured. This permits multiple days of production from one production setup. In this paper, we extend the model to consider additional fixed charges, such as cleanup or inspection costs, that are associated with each time period's production. This manufacturing cost structure is common in the food, chemical, and pharmaceutical industries, where process equipment must be sanitized between item changeovers and at the end of each day's production. We propose two mathematical problem formulations and optimization algorithms. The models' unique features include regular time production constraints, a fixed charge for each time period's production, and the availability of overtime production capacity. Experimental results indicate the conditions under which our algorithms' performance is superior to traditional approaches. We also test the procedures on a set of lot‐sizing problems facing a national food processor and document their potential economic benefit. 相似文献

Advances in information technology, particularly in the e‐business arena, are enabling firms to rethink their supply chain strategies and explore new avenues for inter‐organizational cooperation. However, an incomplete understanding of the value of information sharing and physical flow coordination hinder these efforts. This research attempts to help fill these gaps by surveying prior research in the area, categorized in terms of information sharing and flow coordination. We conclude by highlighting gaps in the current body of knowledge and identifying promising areas for future research. 相似文献

This analysis contributes to LGBT campus climate research on the quality of campus life in higher education in the United States. We argue that public education institutions in different states face divergent impediments to improving campus climate, and that more research is needed identifying structural factors affecting campus climate. Using a social systems analysis of policymaking at one university as a case study, we illustrate how partisan politics and state regulation make Virginia colleges and universities more vulnerable to political scrutiny and control. Finally, we propose a social justice-oriented policy agenda to address structural inequalities. 相似文献

Reconfiguration of the supply chain network from time to time is essential for businesses to retain their competitive edge. This paper presents a methodology for reconfiguration of an existing supply chain network. The methodology is characterized by two decision levels. In the first level, the current network performance is evaluated and efficient practices are identified. In the next level, a model that incorporates efficient practices is developed to reconfigure the network. This integrated methodology allows for decision maker (DM) input throughout the process. The methodology has been implemented and tested in the reconfiguration of an outbound petroleum supply chain network for CountryMark Cooperative, Inc. In this case study, Data Envelopment Analysis (DEA) is used to analyze current operations and an integer programming (IP) model that incorporates efficiency metrics is developed for selection of distribution facilities and allocation of resources to the facilities. Use of this methodology can lead to improved operations and reduced operating expenses. 相似文献

We use household-level data to explore residential electricity use patterns following installation of solar panels. Solar adoption leads to an increase in total electricity consumption relative to a matched non-adopting control group. Our point estimate translates to a rebound effect of 28.5%, suggesting that nearly a third of the electricity produced by a customer's solar panels is used for increased energy services, rather than reduced grid electricity consumption. We explore several potential drivers of an increase in electricity consumption. These results have important implications for electricity planning and policy, suggesting that rooftop solar stimulates additional demand for electricity. 相似文献
