In Belgium as in many other countries, agricultural land is under pressure for development of other land uses. This paper presents a method for setting priorities for preservation of land for agriculture. The method is based on a participatory approach through which a value tree is formulated. This results in a list of criteria to define farmland value, which is explicitly linked to the objectives for farmland preservation. The value tree allows the list of criteria to be determined in a structured and consistent way. The participatory process contributes to the development of a shared vision on farmland preservation. The approach also incorporates context specificity, as shown by its application for farmland preservation in Flanders.  相似文献

This article qualitatively identifies and explains the barriers that foreign cleantech start‐ups can encounter when attempting to enter the Chinese market, as well as the possible strategies that can help overcome these barriers. We base our analysis on interviews with Chinese and foreign entrepreneurs and facilitators. To structure the analysis of such barriers, we use the components of the entrepreneurial ecosystem. We then explain the barriers using institutional theory. We demonstrate that they are caused either by the regulations in China or by the difference between Chinese and Western logics. We further recommend that cleantech entrepreneurs come prepared to China, remain flexible, associate themselves with reputable partners and take advice from those familiar with business in China. Cultural–cognitive barriers might be overcome by integrating the communities of foreign and Chinese start‐ups. Regulative barriers can be removed by the Chinese Government, but this conflicts with the logic of state control. Copyright © 2015 John Wiley & Sons, Ltd and ERP Environment  相似文献

This article analyzes how sociodemographic characteristics impact the adoption of online grocery shopping, and relies on the Motivation-Opportunity-Ability (MOA) model to explore what these sociodemographics actually capture and how they are linked with consumer motivations. The researchers exploit a survey among 468 customers of Belgian supermarket chain Colruyt. Their logistic regression shows that while variables at the personal level do affect adoption of the online channel, consumers’ motivations to adopt in fact lie on the household level. In particular, the effect of age disappears or becomes less strong when it is combined with household characteristics. An examination of respondents’ self-reported motivations confirms that age does not only capture a person’s ability to use the technology but also its usefulness for that person’s household, in that age is correlated with the presence of young children and the working situation in the household.  相似文献

Since public networks became widespread, doubts have arisen over how to make them succeed. Scholars have traditionally addressed the issue in different ways, thus variously shedding light on the network structure, mechanisms, or managers as predictors of the network performance. The aim of our article is to explore the possibility of an interaction effect between the abovementioned factors. Our results show that there may be a relationship between network structure, mechanisms, and managers that jointly affects network performance. Therefore, important suggestions can be made about how to manage public networks successfully: (1) ensure that your network mechanisms and managerial abilities are coherent with the structure of your network; and (2) if you are in a well-established and integrated network, allow yourself some flexibility. Data were collected through a multiple case study that focused on collaboration for joint provision of home care services in Switzerland.  相似文献

工程中的伦理问题及工程师的责任   总被引:1,自引:0,他引:1  
工程中的伦理问题在工程活动的过程中表现为设计的伦理问题、实施的伦理问题和导致人工物(如工厂、民用工程建筑物及基础设施)和环境之间的关系问题。设计是工程的起始阶段并且是工程过程特性的重要体现。工程设计既限制又使得人类的活动被介入到世界和自然过程创造人工物的实施阶段。工程的结果拓展了人类的能力并调节了人类行动的许多方面。因此,工程被解释为引发在物理世界和人们活动世界中的具有因果关联和象征性属性的人工现实。工程人工物或者基础设施形塑社会和自然环境,它们因此也能够被评估。工程师的责任有设计责任、关照工程成果的责任及维护社会和自然环境的责任三种类型。  相似文献

More diverse, perennial cropping systems often have better natural mechanisms for keeping pests at bay. But while scientists emphasise the broad benefits of conservation in terms of effective ecosystem functioning, farmers are more interested in biodiversity for the provision of food or of services such as shade or windbreaks. Because of their limited knowledge of the role of biodiversity in plant protection, farmers sometimes unconsciously disturb natural regulatory mechanisms. Some citrus farmers in Vietnam introduced sapodilla as an intercrop to diversify their source of income, and because this fruit tree requires little care. However, this apparently worthwhile attempt to combine two valuable crops has misfired. The ecological conditions that traditionally sustained natural pest control in citrus have been disturbed, thus trapping farmers in the pesticide treadmill. The weaver ant Oecophylla smaragdina stopped protecting citrus from stinkbugs and leaf-feeding caterpillars after facing competition from the black ant Dolichoderus thoracicus, which favours sapodilla trees as a nesting habitat. To avoid similar scenarios in the future, methods for linking scientific research on ecosystem functions with farmers' own knowledge, experience and priorities are presented. Examples are given of ways in which farmers in perennial cropping systems learn, and how scientists can facilitate this learning process.  相似文献

We construct a new data set of consumption and income data for the largest US metropolitan areas, and we show that the extent of risk-sharing between regions varies substantially over time. In times when US housing collateral is scarce nationally, regional consumption is about twice as sensitive to income shocks. We also document higher sensitivity in regions with lower housing collateral. Household-level borrowing frictions can explain this new stylized fact. When the value of housing relative to human wealth falls, loan collateral shrinks, borrowing (risk-sharing) declines, and the sensitivity of consumption to income increases. Our model aggregates heterogeneous, borrowing-constrained households into regions characterized by a common housing market. The resulting regional consumption patterns quantitatively match those in the data.  相似文献

Given a segmentation problem, marketers may be forced to consider the benefits of both general and product-specific life style segmentations. This study therefore explores the procedures and refinements associated with each approach and offers overall conclusions as to each one's efficacy.  相似文献

In this paper, a method is proposed by which management is able to analyze the risk-return tradeoff for various levels of liquid assets for the firm and for different maturity compositions of its debt. Together, these factors determine its working-capital position. Certain probability concepts are employed; and information is provided about the risk of cash insolvency for alternative strategies. In addition, the opportunity costs of these strategies are determined. With the framework proposed, more rational working-capital decisions are possible. The firm is able to achieve a working-capital position that provides the appropriate margin of safety in relation to the cost involved in attaining that position  相似文献

This paper presents results from the Iris Futures research project. The research was aimed at exploring the potential role of foresight in the development of the Brussels Capital Region and the identification of tools, capabilities and conditions for an improved application of foresight in Brussels. An overview was created of the characteristics of 60 future oriented activities and 120 organisations involved in such activities At the outset questions on organisational or institutional fragmentation and collaboration were not intended to be in the foreground of the research but over the course of the research this issue was observed to have a significant adverse impact on foresight capacity in Brussels. The case of the Brussels Capital Region demonstrates that institutional and organisational fragmentation need to be overcome for a futures oriented practice to have opportunity. De-fragmentation, bottom-up and institutionally, is both a condition for and an effect of the futures oriented practice underlying the foresight capacity of organisations.  相似文献
