This paper is based on evidence from a survey, conducted during 1992, investigating the adoption of electronic data interchange (EDI) amog neraly 20 furms in the pharmaceutical and healthcare sector within the UK. In particular, it focuses on the factors behind the adoption and diffusion of EDI, and the barriers to its uptake and spread. It also analyzes some of the strategic, organizational and managerial issues behind its implementatio and development. The survey highlights the relatively slow rate of adoption of EDI within this sector and key problems that inhibit its uptake. These include issues of costs, standards and the increasingly fragmented nature of purchasing and logistics that results from reorganization within the UK healthcare system.  相似文献

The effect of zoning on land value   总被引:1,自引:0,他引:1  
Two types of zoning are identified: externality zoning, which is designed to achieve a Pareto efficient pattern of land use, and fiscal zoning, which is designed to accomplish some other objective. (The latter, for instance, may be aimed at minimizing the tax rate in a community.) The paper shows that it is not in general possible using a priori theory to predict the sign (positive or negative) of the effect of either of these forms of zoning on aggregate land value in a community. It is shown, however, that under plausible assumption it can be argued that zoning as currently practiced in many U. S. communities probably has the effect of lowering aggregate land values in the communities doing the zoning.  相似文献

This paper poses a model of the effects of job suburbanization and suburban exclusionary zoning on the welfare of blacks and other urban minority groups. It explores the circumstances under which blacks take suburban jobs and whether they are made better off if they do so. The possibilities that blacks outcommute from central area ghettos and that they relocate to suburban housing near the jobs are each considered. A hypothetical governmental project to subsidize the creation of 10,000 suburban jobs for blacks is explored in a cost-benefit framework, stressing the effects of suburban exclusionary zoning on the project's feasibility.  相似文献

Although globalisation is not a recent phenomenon, it is the trend toward trade liberalisation that poses the greatest threat to small countries. The paramount question is how can small states buffeted by the forces of trade liberalisation attract foreign investment while protecting their populations from the foreign control of land. Using St. Lucia as a case study, this paper reviews the existing land tenure system, examines the force of current legislative, fiscal and land use policy instruments used to limit foreign control of land, and presents alternatives for curtailing the potentially negative effect of trade liberalisation on the foreign control of land.  相似文献

The international ski tourism industry is highly vulnerable to inter-annual climate variability and climate change. Accordingly, there is a strong need to advance our understanding of climate risk for this multi-billion tourism market that is so important to mountain regions around the world. This study addressed major limitations in the ski tourism literature, while concurrently supporting priority information needs of ski tourism stakeholders. An improved version of SkiSim 2.0 is applied to all 34 alpine ski areas in southern Ontario (Canada) to examine potential changes in the capacity of this regional marketplace. Model improvements include differential snowmaking capacities of individual ski areas, updated snowmaking decision rules, as well as a new indicator, termed ‘terrain-days’, to estimate changes in system capacity. The results project two fundamentally different futures for this ski tourism marketplace under climate change. If the international community succeeds in achieving the?+?2°C Paris Agreement policy goal, then losses in system capacity can be limited to less than 10% in the mid- and late-century. In contrast, a high-end emission scenario (RCP 8.5) would severely disrupt this ski tourism market by mid-century, with system capacity losses between 28% and 73%.  相似文献

This paper reports results derived from a survey of 2229 residents of, and 2151 visitors to the island of Waiheke, New Zealand. The study finds there was a close similarity of place image held by both visitors and residents. The paper examines the proposal that where congruency exists between visitor and resident image of place, there may be less negative perceptions of visitor impact on the part of residents. Both qualitative and quantitative data were collected and analysed, the former involving the use of CatPac?, a neural network program for analysing textual data. Little support was found for the contention that place images shared by residents and tourists would increase tolerance of tourists on the part of residents.  相似文献

This study examines a public debate in Australia, arising from a national government report, around how social contribution in the nonprofit sector should be assessed. Guided by several meta‐perspectives on evaluation, we identify connections between foundational assumptions and normative positions on evaluation espoused by non‐profit organizations (NPOs), and examine the ways in which the inter‐paradigmatic context of the non‐profit sector contributes to the emergence of NPOs’ different normative positions on evaluation. We conclude that particular paradigmatic orientations of NPOs (positivism, interpretivism, constructivism) lead to particular perspectives on how NPOs should engage with alternative paradigms (monism, impartial pluralism, radical pluralism).  相似文献

Smooth and Sticky Adjustment: A Comparative Analysis of the US and UK   总被引:4,自引:0,他引:4  
This paper adopts the methodology of the microeconometric labor literature to analyze a common assertion from trade economists that reallocation within sectors is less costly than between sectors. Findings are compared across two countries (the UK and US) which have experienced very different recent aggregate unemployment experiences. Workers previously employed in "declining" sectors are more mobile than those employed in 'expanding' sectors in both countries, and individuals are more likely to switch sector the longer they are unemployed. A plausible explanation for this is that individuals initially attempt to find jobs that complement their general and specific skills in order to accrue the associated rewards, and move sector only as this prospect diminishes. This would seem to accord with the 'smooth adjustment hypothesis' which proposes that intraindustry adjustments are less costly than interindustry ones.  相似文献
