We use contingent valuation (CV) and choice experiment (CE) methods to assess cattle farmers’ attitudes to and willingness to pay (WTP) for a bovine tuberculosis (bTB) cattle vaccine, to help inform vaccine development and policy. A survey questionnaire was administered by means of telephone interviews to a stratified sample of 300 cattle farmers in annually bTB‐tested areas in England and Wales. Farmers felt that bTB was a major risk for the cattle industry and that there was a high risk of their cattle getting the disease. The CE estimate produced a mean WTP of £35 per animal per single dose for a vaccine that is 90% effective at reducing the risk of a bTB breakdown and an estimated £55 for such a vaccine backed by 100% insurance of loss if a breakdown should occur. The CV estimate produced a mean WTP of nearly £17 per dose/per animal/per year for a vaccine (including 100% insurance) which, given the average lifespan of cattle, is comparable to the CE estimate. These WTP estimates are substantially higher than the expected cost of a vaccine which suggests that farmers in high risk bTB ‘hotspot’ areas perceive a substantial net benefit from buying the vaccine. 相似文献

In this paper we present a multi-disciplinary analysis of the potential impacts of undertaking similar environmental actions on multiple farms in a small geographic area, using organic farming as a proxy for a co-ordinated approach. Recent papers have called for more co-ordinated efforts between farmers in terms of their environmental actions, but there has been limited applied research demonstrating the environmental benefits or the economic and social implications to farmers of this approach. Comparative analysis of biodiversity, soil and water, and farm profitability were undertaken in England on 32 matched farms in areas of low and high organic farming concentration; qualitative interviews were also conducted with 48 farmers living in two of the eight areas. Findings demonstrate higher overall levels of biodiversity on organic farms (particularly in “hotspot” areas) but this was not universal across the species groups investigated. Higher water infiltration rates were found in organic grasslands, which could prove to be a useful measure to combat flooding. In terms of the technical efficiency of producing these environmental gains, conventional and organic farms in hotspot areas demonstrated equivalent efficiency from a financial perspective. Socio-cultural research identified the different amounts of trust farmers have in their neighbours, based in part on their performance as ‘good farmers’. We discuss the neighbourhood effect with a multi-disciplinary approach and conclude that encouraging local farmer co-ordination can have clear environmental benefits without high economic cost, but must be undertaken with caution - specifically regarding the trade-offs between benefits, local geophysical and social characteristics, and assumptions made about inter-farmer trust. 相似文献

This study examines economic performance, environmental performance, and regulatory activity for plants in three industries: pulp and paper, oil, and steel. Stochastic frontier production function models show significant deviations from production efficiency. Older plants are less efficient in production, but perform no worse on emissions. Plants spending more on pollution abatement tend to do worse on both production efficiency and emissions. Stricter local regulatory pressure is associated with somewhat lower emissions, but has mixed effects on production efficiency. Positive correlations between SUR residuals for emissions and production efficiency suggest unmeasured plant-level characteristics that drive both economic and environmental performance.

Railway fatalities account for approximately 10% of transport fatalities in Cape Town. The objective of this study was to examine alcohol intoxication as a risk factor during daylight hours by conducting a case - control study to compare rail passenger and pedestrian fatalities (cases) with motor vehicle passenger and pedestrian fatalities (controls). Rail passenger and rail pedestrian fatalities were defined as cases with motor vehicle passenger and pedestrian fatalities as the respective controls. Data were collected from post-mortem reports at two mortuaries from 1994 to 1996. Blood alcohol concentration was the dependent variable. The independent variables were age, gender, date of death, day of week, time of injury and external cause of death. The late afternoon and early evening period from 1600 hours to 1900 hours had the highest frequency of fatalities for all case and control groups. Of the 56 predominately male (89%) railway passenger cases with an average age of 34.5 (SD 12.5) years, Friday (27%) was the most frequent day of death. Railway pedestrian cases (89% male, average age 36.8 years (SD 13.3)) were more likely to be killed on a Monday (11% of cases). Among the controls, motor vehicle passengers (63% male, average age 39.9 (SD 15.5)) were more likely to die on a Sunday (25%) and pedestrians (82% male, average age 41 (SD 14.7)) on a Saturday (21%). The study showed that alcohol consumption is an important risk factor for rail fatalities during daylight hours, with rail passenger fatalities being 4.71 (1.72 - 12.88) and rail pedestrian fatalities 1.62 (0.98 - 2.69) times more likely to be intoxicated than the respective controls. The results provide more evidence for public health campaigners to tackle endemic alcohol abuse and to develop diverse interventions that do not exclusively target motor vehicle drivers. 相似文献

Abstract: China's relationship with Africa has grown exponentially over the last decade with US$95 billion in bilateral trade in 2008 and US$5.4 billion of Chinese investment in Africa for the same year. The growth of Sino‐African relations also has an impact on the role of traditional development partners in Africa in particular in the aftermath of the 2008 financial crisis, which has already led some traditional development partners to reduce their aid budgets and subsequently their Official Development Assistance (ODA) flows to Africa. The objective of this paper is to analyse different development cooperation modalities in Africa of traditional development partners and China. This requires identifying trends in aid, debt relief, general budget support, trade, preferential trade access, and investment flows of both traditional development partners and China. The paper advocates that complementarities can be built between these development modalities on a national, regional and global level. This would enhance development effectiveness, increase efficiency and create win‐win situations which would be beneficial to African countries, China and traditional development partners. 相似文献

The determinants of Internet financial reporting 总被引:1,自引:0,他引:1
Responding to the widespread adoption of the Internet and the rapidly growing demands for information from stakeholders, corporations around the world are using the Internet for business and financial disclosures. Internet reporting has the benefits of low cost, wider reach, frequency and speed. Despite these benefits Internet reporting varies across companies and across countries. We study Internet financial reporting (IFR), in particular the presentation and content of IFR, of 660 large companies in 22 countries to identify the firm, and environmental determinants of IFR. The study revealed that firm size, listing on US stock exchanges and technology were firm specific determinants of IFR. Given that IFR is not just about the content of disclosure, but also about employing new presentation methods, the environment of disclosure was included in the research. The overarching disclosure environment of a country was found to be an important environmental driver for IFR presentation and less strongly for IFR content. The presentation aspect of IFR was more associated with the identified determinants than the content of IFR, which suggests that Internet presentation technologies were more related to the determinants than the content of the reports on the company Web sites. 相似文献

Recent empirical assessments revealed that footprint indicators calculated with various multi-regional input–output (MRIO) databases deliver deviating results. In this paper, we propose a new method, called structural production layer decomposition (SPLD), which complements existing structural decomposition approaches. SPLD enables differentiating between effects stemming from specific parts in the technology matrix, e.g. trade blocks vs. domestic blocks, while still allowing to link the various effects to the total region footprint. Using the carbon footprint of the EU-28 in 2011 as an example, we analyse the differences between EXIOBASE, Eora, GTAP and WIOD. Identical environmental data are used across all MRIO databases. In all model comparisons, variations in domestic blocks have a more significant impact on the carbon footprint than variations in trade blocks. The results provide a wealth of information for MRIO developers and are relevant for policy makers designing climate policy measures targeted to specific stages along product supply chains. 相似文献

A form of strategic mediatization, media catching is the reversal of the traditional public relations process of pitching story ideas to journalists using press releases, feature pitch letters, and other techniques. In media catching, journalists working on specific stories reach out to large numbers of public relations practitioners using a variety of technologically aided services with queries for specific information. Using quantitative and qualitative content analyses, this study examines journalist queries submitted through a media request service, Pressfeed.ru, to understand the dynamics of the media-catching trend in Russia. Findings show a substantial gap between reporters’ expectations and public relations professionals’ goals and abilities, and a fragmentation of media outlets’ practices. The findings also revealed similarities in the growth and usage patterns of the Russian service to the first American media-catching service, Help-a-Reporter-Out. An empirical investigation is warranted to test an emergent model of the mutual influences of reporters, public relations specialists, internal (organizational values) and external (societal culture, political climate) factors during the process of media catching across different cultures and countries. 相似文献

Distance functions are increasingly being augmented, with environmental goods treated as conventional outputs. A common approach to evaluate the opportunity cost of providing an environmental good is the exploitation of the distance function's dual relationship to the value function. This implies that the opportunity cost is assumed to be non‐negative. This approach also requires a convex technology set. Focusing on crop diversification for a balanced sample of 44 cereal farms in the East of England for the years 2007–2013, this paper develops a novel opportunity cost measure that does not depend on these strong assumptions. We find that the opportunity cost of crop diversification is negative for most farms. 相似文献
