Agri-environment schemes (AES) favouring the maintenance of hedges were implemented in the Camargue (southern France) as it has previously been proven to reduce the risk of damage caused by Greater Flamingo incursions into rice fields. Given the persistent incursions, we estimated the economic cost of damage from 2007 to 2009, the uptake rate of hedge-related AES and explored the limits of these schemes as a mitigation effort. Semi-structured and key informant interviews, site mapping and field visits were made to verify claims and estimate damage. Number of plants/m2 and fertile stems/plant were estimated on 1,498 and 312 grids, respectively, spread over 26 rice fields. Damaged areas of rice fields forayed by flamingos presented from 1.35 to 3.06 t/ha lower yield than undamaged areas. We estimated 228€/ha average loss in forayed fields for a total of 400,000€ in yield loss in 2008. Administrative constraints limited AES and free seedlings distribution, preventing the problem from being addressed at an appropriate scale. The trivial financial support for hedge management relative to more lucrative AES with lower constraints resulted in low uptake rate. We propose that modifications of AES take into account landscape factors over administrative boundaries and that the financial support for AES be scaled up relative to other subsidies in order to address the efforts necessary to achieve landscape changes to reduce human–wildlife conflict. 相似文献

In many north-western European countries, the family practices of drinking and eating used to be largely located in the private domain of the home. This situation has recently begun to change, particularly in gentrified urban areas where middle-class families are growing in number and family outings in bars and restaurants are becoming more widespread. This paper examines the new practices of family consumption from two perspectives: the providers and the consumers. Entrepreneurs shape family-friendly spaces by reducing boundaries between eating, drinking and playing and by offering out-of-home pleasures in home-like environments for both parents and children. They balance between accommodating the families and retaining their childless clients. Families that consume in the food and drink spaces are primarily local middle-class families, and fathers and mothers equally participate. This study further reveals that leisure time spent with the family cannot always be classified as leisure time as a family. Parental involvement with the children differs. We distinguish leisured caring time with high parental involvement, own leisure time mainly directed at parents’ personal activities and social leisure time mainly directed at maintaining social relationships beyond the family. We discuss earlier research on the complicated character of family leisure related to the caring duties of parents. Empirical evidence comes from an exploratory study of ten consumption spaces in the inner city of Amsterdam, The Netherlands. 相似文献

Monitoring and evaluation are tools that can facilitate sustainable and responsible tourism planning and management in organisations through encouraging good practice and the continuous improvement of programmes. However, to date, there is limited knowledge and understanding of how, or indeed if, volunteer tourism organisations actually monitor and evaluate their programmes. The aim of this paper is to identify and critically examine the extent to which volunteer tourism organisations engage with the monitoring and evaluation of their projects. Based on a survey of 80 organisations and qualitative interviews with representatives from 29 organisations, the research found that monitoring and evaluation practices vary greatly. Participants readily accept a lack of time and resources as barriers to monitoring an evaluation, there is an assumption that any volunteer-host community interaction is positive, and despite voluntary guidelines, there is little incentive to prioritise monitoring and evaluation of volunteer programmes. A small number of volunteer organisations emerged as an exception to this overall pattern and are discussed. Discrepancies between stated importance of monitoring and evaluation and actual practices are examined and opportunities for improved practices identified. 相似文献

We examine the implications of the liberalised economic conditions associated with the economic transformations in the transition countries of Central and Eastern Europe (CEE) and Commonwealth of Independent States (CIS) for R&D and innovation in the food processing sector. We use a dataset derived from the World Bank's Business Environment and Enterprise Performance Surveys (BEEPS) database to examine the relationships between R&D/innovation activities in food processing firms in transition countries and (i) privatisation, (ii) foreign direct investment, (iii) trade activities, (iv) market competition pressure, and (v) economies of scale. The empirical analysis is implemented through: (i) a double‐hurdle model for R&D participation and expenditures, and (ii) a bivariate probit model for product and process innovation. We find that these economic transformations generally promote R&D/innovation activities in the food processing sector. Our results suggest that broadened and deepened economic liberalisation policies would improve the innovation performance of the food processing sector in transition countries, and would enhance competitiveness in domestic and foreign markets. They also indicate that innovation policies may need to be tailored to market and industrial characteristics of different transition regions. 相似文献

This paper presents evidence on the financial policies of firms strongly engaged in research and development activities. By referring to the under-investment paradox, the asset substitution problem, the asset specificity proposition and the information asymmetry literature, we postulate that R&D-intensive firms should adopt specific financial policies. In conformity with our hypotheses, empirical results based on a sample of R&D-intensive and non-R&D firms in four major industrialized countries (Europe, the UK, Japan and the US) show that R&D-intensive firms exhibit significant lower debt and dividend payment levels, but shorter debt maturities and higher cash levels than non-R&D ones. 相似文献

The general equilibrium model with incomplete markets is here extended to infinite horizon economies populated by a finite number of infinitely lived agents. the crucial issue that divides the infinite horizon setting from the finite horizon setting is in the nature of borrowing constraints, which added to spot constraints, define a plausible budget set for individual agents. the paper relates seven alternative definitions of equilibrium and states corresponding equilibrium existence theorems when assets are one-period and purely financial. 相似文献

To analyse the historical evolution of the building sector in Chile, and the way in which it reflects and affects the social structure as a whole, it is necessary to consider two aspects:
- 1 the building sector, considered as a specific part of the production sphere, a specific system of economic and social interests;
- 2 the building front, where the social practices of the conflicting forces express the needs of the reproduction of the labour force, and the class struggle in the building sector, opposed to speculation and capital accumulation processes.

This paper studies the existence of solutions in continuous time optimization problems. It provides a theorem whose conditions
can be easily checked in most models of the optimal growth theory, including those with increasing returns and multi-sector
economies.

The intent of the research was to examine the relationships between support, trust, satisfaction, commitment and work outcomes. The framework of social exchange theory was used as a guide. The research described in this study replicates in the public sector (N = 704) and previous findings obtained in a study conducted in the private sector. Consistent with the study in private sector, support is related to intention to leave and helping behavior to trust and satisfaction. Results are discussed. 相似文献
