In this article we present a review of literature on the concept of Artefact, Tool and Technical Object in the light of in sociocultural approach. Particular attention is given to present and discuss the French research tradition on the Technical Object and Technological education. The aim is to give a broad perspective to explore the mediation between the individual and their environment.  相似文献

This paper analyses the potential effect of local agro-environmental policies in promoting multifunctionality in a rural landscape, with a two-scale modelling framework: a regional scale for food demand and a local scale for the forces driving land use. The framework has been designed in four steps. First, the relative influence of the driving factors on the current land use pattern has been analysed. Two scenarios are designed that vary the external demand for the total land use, and alter more or less quickly the specific location factors that drive the landscape pattern. The first scenario considers trends in the external and internal driving forces. The second relies both on totally decoupled farm subsidies and unregulated housing growth. In both scenarios a local agro-environmental policy is introduced and we compare its consequences with the previous scenario's landscape pattern. The third step consists of a modelling exercise that analyses the likely outcome of each scenario on the development of land use patterns on a local scale. Last, these landscape patterns have been translated into ecological indexes that assess the effect of the policy options on the multifunctionality of the local landscape.  相似文献

A six-stage model of the buying process for ERP software   总被引:1,自引:0,他引:1  
This paper presents a model of the Enterprise Resource Planning (ERP) software acquisition process that reflects the findings from the four cases examined in this study. This ERP acquisition process model includes six distinctive, yet interrelated, processes (planning, information search, selection, evaluation, choice, and negotiations). This paper depicts the principal processes and many of the constituent activities, issues, dynamics, and complexities that pertain to the acquisition of ERP software. The results from this study contribute to the identification of processes that are part of this type of acquisition. Further, this model also suggests complexities that are worthy of further investigation, in and of themselves, if for no other reason than that they could prove the limit of generalizability of the model.  相似文献

Few studies on the entrepreneurial contributions of immigrant and/or ethnic entrepreneurs have been carried out in Canada. This article presents results from a cross‐Canadian project. Data were collected from 718 entrepreneurs in three cities. Analysis of the socio‐demographic profile suggests that ethnic entrepreneurs pursue different paths of integration. Firm characteristics suggest that similar support programs are needed for ethnic firms as for all small firms. Also, our analysis suggests that there is no need for new support programs for ethnic firms, except to help them better integrate. Lastly, the use that these entrepreneurs make of social capital only partially confirms the literature. © 2010 Wiley Periodicals, Inc.  相似文献

The ESPON 2006 scenario project generated three integrated roll-forward scenarios (A roll-forward scenario is a scenario in which the hypotheses define the parameters at the start of the covered time period and the scenario then explores the unfolding of events based on theses hypotheses. This is opposed to a roll-backward scenario in which the situation at the end of the time period is defined and the scenario then explores the path to reach this situation.). In the trend scenario renewed efforts are made for the Lisbon strategy, demanding extra investments in R&D and education. Regional policy will also be continued with vigour. In the Competition Scenario bold decisions are made regarding Europe's continued prosperity. The Lisbon strategy takes precedence over institutional reform and other sectoral policies. In the Cohesion Scenario Europe is confronted with the challenge of fully integrating the various regions in Europe. The budgets for Regional Policy and Rural Development Policy are enhanced and targeted to the most needy regions. The scenarios are described as stories about the future, supported by model calculations and visualised by various maps. They concentrate on urban and rural development and on territorial developments in different parts of Europe, like North-West Europe, the Alpine Space and Central and Eastern Europe. In addition, a proactive, roll-back scenario explores the possibilities to combine competitiveness, cohesion and sustainability. A message, derived from the scenarios, is that independent of the explored policy options the European territory will be confronted with large challenges like a (rapid) decline of fossil energy resources and increasing impacts of climate change. The scenarios appear particularly helpful in the context of the current paradigm shift in European regional policy from a policy for balance to a policy for aggregate growth.  相似文献

Both bribery and extortion weaken the power of incentives, but there is a trade‐off in fighting the two because rewards to prevent supervisors from accepting bribes create incentives for extortion. Which is the worse evil? A fear of inducing extortion may make it optimal to tolerate bribery, but extortion is never allowed. Extortion discourages “good behavior” because the agent suffers from it even though he has done the right thing, whereas a bribe acts as a penalty for “bad behavior.” Our analysis provides lessons to fight corruption and explanations why developed countries may have an advantage in dealing with extortion.  相似文献

An emerging environmental management tool is the corporate environmental report, a free-standing document, analogous to the corporate annual report, but which covers environmental and often health and safety issues. This study examines the nature of the corporate environmental reports of large, public, US companies to determine which companies produce reports, what type of information is reported, how this information is presented, and who might be the audiences for this information. This study also seeks to identify state of the art practice in corporate environmental reports, drawing on the US reports and leading environmental reports from Europe and Canada. Over 100 US companies now publish corporate environmental reports. These companies are primarily from the manufacturing sector, although they are increasingly part of the service sector. Report issuers identified employees and shareholders as their primary audiences. Both overall report organization and composition as well as report distribution, including the use of the Internet for environmental reporting, were examined. Topics which reflect leading edge environmental practice are identified and examples from reports are given. These topics include integrating business and environmental performance, environmental policy, goals and measurement, management and organizational structure, environmental and resource data presentation, third-party verification, disclosure of negative information, and sustainability. The paper discusses trends in reporting and makes recommendations to improve reports.© 1997 John Wiley & Sons, Ltd and ERP Environment.  相似文献

This paper, following earlier work on the measurement of inequality when only ordinal information is available, proposes an axiomatic derivation of a new class of inequality-sensitive and additive achievement measures. Use is then made of these indices to study health achievement in Europe, using information on self-assessed health in 30 countries, based on the European Health Interview Survey (wave 2).  相似文献
