Abstract

Views on the preservation of resources versus their development for recreation are compared among participants in three types of outdoor recreation: “appreciative”; activities (cross‐country skiing, hiking, and canoeing); “consumptive”; activities (fishing and hunting); and “mechanized”; activities (motorboating, snowmo‐biling, and trail biking). The results from a 1984 questionnaire survey conducted in Edmonton and Calgary, Canada, indicate a stronger preservationist orientation among participants in appreciative activities, whereas (with the exception of hunters) participants in consumptive and mechanized activities hold stronger pro‐development views. These differences cannot be attributed to simultaneous variations in socioeco‐nomic characteristics or environmental attitudes among the recreational groups. The findings suggest that differences in outdoor recreational activity preferences represent an important source of variation in views about appropriate levels of preservation versus development of Alberta's natural and wildernesss resources.  相似文献

The goal of this paper is to consider pure jump Lévy processes of finite variation with an infinite arrival rate of jumps as models for the logarithm of asset prices. These processes may be written as time-changed Brownian motion. We exhibit the explicit time change for each of a wide class of Lévy processes and show that the time change is a weighted price move measure of time. Additionally, we present a number of Lévy processes that are analytically tractable, in their characteristic functions and Lévy densities, and hence are relevant for option pricing.  相似文献

This paper examines recreation and leisure research within the context of active living, and highlights an apparent gap between the current involvement of recreation and leisure researchers and the potential they could offer to this important and expanding area of inquiry. To illustrate this potential, I looked at two previous studies that focused on the recreational use of urban trails and reanalyzed the data from an active living perspective. In Study 1, individual, social and environmental factors helped distinguish between low, moderate, and high activity level trail uses. In Study 2, use patterns helped distinguish between health-motivated trail users and individuals using trails for recreation and other purposes, but perceptual and demographic data were similar among groups. Findings from similar studies can help inform active living research, and recreation and leisure studies can provide leadership and contributions to a transdisciplinary understanding of active living.  相似文献

Abstract

The appropriate tool for measuring and managing marketing productivity is the present value of the total dollar contribution produced, divided by the total dollar value of the marketing effort expended to produce it. This ratio is referred to as the contribution return on marketing effort or CRM ratio. CRM integrated with activity based costing (ABC) and activity based management (ABM) systems, value analysis and value engineering (VA-VE) techniques offer a viable and practical foundation for managing customer relationship efforts and linking them to customer- and share holder value. The article offers a systematic approach for integrating contribution return on marketing (CRM) with customer relationship management (CRM).  相似文献

Traditionally, accounting has evolved as a technique. Practitioners and academics have striven to improve the technical features of accounting. Now, accounting is conceived increasingly as an organizational artefact which interacts with other organizational practices in shaping organizational reality. Taking a broad perspective of management control, this paper aims at contributing to our knowledge of accounting in this second sense and identifying some Swedish contributions to the tool-box of accounting. In reviewing the development of models of accounting information in Sweden mainly since World War II, different factors explaining the evolution of each model are identified. Analyses of these factors reveal that different groups of actors have been engaged in the development of different parts of the accounting information system (AIS). It is also noted that the introduction of models that are widely applied has delayed the emergence of new models better adapted to the current situation in business. Comparisons will be made with the development in some other countries.  相似文献

The resource‐based view of the firm (RBV) hypothesizes that the exploitation of valuable, rare resources and capabilities contributes to a firm's competitive advantage, which in turn contributes to its performance. Despite this notion, few empirical studies test these hypotheses at the conceptual level. In response to this gap, this study empirically examines the relationships between value, rareness, competitive advantage, and performance. The results suggest that value and rareness are related to competitive advantage, that competitive advantage is related to performance, and that competitive advantage mediates the rareness‐performance relationship. These findings have important academic and practitioner implications which are then discussed. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

In this study we revisit some fundamental questions that are increasingly at the heart of current strategic management discourse regarding the relative impact of industry and firm‐specific factors on sustainable competitive advantage. We explore this issue by referring to respective assertions of two major perspectives that dominate the literature over the last two decades: the Porter framework of competitive strategy and the more recent resource‐based view of the firm. A composite model is proposed which elaborates upon both perspectives' divergent causal logic with respect to the conditions relevant for firm success. Empirical findings suggest that industry and firm specific effects are both important but explain different dimensions of performance. Where industry forces influence market performance and profitability, firm assets act upon accomplishments in the market arena (i.e., market performance), and via the latter, to profitability. The paper concludes with directions for future research that will seek to integrate both content and process aspects of firm behavior. Copyright © 2001 John Wiley & Sons, Ltd.  相似文献

Based on previous empirical research, size is perhaps the most powerful explanatory organizational covariate in strategic analysis. We suggest that theoretical arguments about size be examined carefully to specify models with explicit comparison sets and with mechanisms linking size and underlying processes to outcomes. We illustrate the approach here by advancing arguments about scale competition within an organizational population. In this effort, we feature a theoretical model of scale‐based selection, which posits that a firm's chances of survival decrease with its aggregate distance from larger competitors on a transformed size gradient. The model assumes that the appropriate comparison set consists of all contemporaneous similar organizations competing on the basis of scale and operating in a localized geographic setting. We argue that aggregate distance of a focal firm from larger other firms (a specific form of relative position in the size distribution) reflects the extent to which it can capitalize on potential competitive advantages of scale emanating from economic, political, and social processes. Analyzing the mortality rates of large organizations across the entire histories of automobile industries in four major countries provides support for the theory. We discuss the general implications of our findings for strategic and organizational analysis. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

In a recent paper, Rouse and Daellenbach (1999) provide a five‐step methodological approach which they feel will cure alleged inadequacies in empirical resource‐based research. We suggest, however, that their methodology can provide only a useful aid for expanding our understanding of potential sustainable competitive advantages but will not allow researchers to effectively verify those hypothesized advantages. Specifically, we argue that Rouse and Daellenbach's methodology is plagued by three major shortcomings: (1) it confuses the important distinction between knowing‐how and knowing‐what; (2) it fails to recognize the importance of observable variables in verifying the sources of sustainable competitive advantage; and (3) it calls for sampling on the dependent variable.
