This article presents a straightforward and highly participatory methodology for addressing government agencies’ concerns with effective communication strategies for biosecurity when stakeholders are diverse and there is uncertainty about their levels of knowledge. The case study was among peri‐urban landholders in an area where serious animal disease infestation has occurred within the last 10 years. Initially we engaged stakeholders in a consultative process that included establishing a stakeholder influence and interest map for both weeds and animal diseases. This was followed with a mental model approach involving surveys and in‐depth interviews. We elicited information about landholders’ knowledge, practices, values and beliefs regarding biosecurity risk. Our consultative process generated examples that indicate that effective risk communication relies on establishing and affirming mutual levels of trust and credibility between landholders and agencies. While this finding is not surprising, we argue that attention to stakeholder consultative processes is central to overcoming barriers to changing practices and building awareness. Secondly, our data confirmed that while smaller landholders were the initial target for the communication, all landholders represented a similar level of biosecurity risk. Therefore, our approach was critical in overcoming external assumptions about particular actors. Finally, our data pointed to the need to develop a whole of landscape approach to biosecurity risk communication strategy in consultation with local stakeholders. 相似文献

In this article we examine which farmers would be early entrants into weather‐index insurance markets in Ethiopia, were such markets to develop on a large scale. We do this by examining the determinants of willingness to pay for weather insurance among 1,400 Ethiopian households that have been tracked for 15 years as part of the Ethiopian Rural household Survey. This provides both historical and current information with which to assess the determinants of demand. We find that educated, wealthier individuals are more likely to purchase insurance. Risk aversion is associated with low insurance take‐up suggesting that models of technology adoption can inform the purchase and spread of weather index insurance. We also assess how willingness to pay varied as two key characteristics of the contract were varied and found that basis risk reduces demand for insurance particularly when the price of the contract is high, and that provision of insurance through groups is preferred by female headed households and individuals with lower levels of education. 相似文献

This article compares violations of minimum wage laws and other labour standards in New York City, Los Angeles and Chicago. Los Angeles has the highest violation rates, due to such factors as its industrial composition and disproportionately large number of small establishments, as well as its vast unauthorised immigrant population. In addition, Los Angeles’ higher rates reflect the stricter legal standards in California. We conclude that, although stronger workplace laws and regulations are crucial, in the absence of effective enforcement, they may fail to prevent workplace violations. 相似文献

This article proposes an alternative framework for understanding enterprise unionism by emphasizing political dynamics and the role of the state in labour relations. Our framework delineates the strategic behaviour patterns of each of the tripartite IR actors under collective bargaining. It maintains that the initial period of the collective bargaining era constituted a critical juncture for state labour policy that occurred in distinctive ways in different countries and that these differences played a central role in shaping the different union structures in the following decades. Our historical analysis shows that unlike its Western counterparts, the Japanese state was able to eradicate the horizontal union movement at the onset of the collective bargaining era because of its advantages as a late developer and Cold War politics, which resulted in enterprise unionism in Japan. 相似文献

This study in 29 Chinese organizations contributes to our understanding about work-related values in China. Empirical research
in Chinese organizations indicates differences in work-related values between different age groups. The authors compared people
(older age group) with work experience from the pre-reform period – pre-1978 China, with those who started their work life
in a society that had already changed and become open to foreign investments (younger age group). The authors created a model
of institutionally sensitive work-related values. The results could help multinational companies achieve competitive advantage. 相似文献

The current note clarifies that Condorcet Jury Theorem cannot be generalized to the extended setting where individual decisional
skills are not assumed to be exogenous parameters even when these skills are homogeneous. This is true when skills are determined
endogenously either by a central planner or, in a decentralized strategic setting, by the decision makers themselves. 相似文献

Water Resources in the Asia-Pacific Region: Managing Scarcity 总被引:1,自引:0,他引:1
Irrigation, together with improved crop varieties and substantial growth in fertiliser use in the late 1960s through the early 1980s, was a key factor in stimulating strong agricultural growth in much of the Asia-Pacific region. New sources of water are increasingly expensive to exploit, but irrigation continues to be a major catalyst for agricultural growth. In the face of increasing degradation, the maintenance of the water resource base must be a high priority policy objective. This paper reviews the management of water resources in the Asia-Pacific region, for countries with significant irrigated area: Cambodia, China, Indonesia, Korea-DPR, Republic of Korea, Laos, Malaysia, Mongolia, Myanmar, Philippines, Thailand and Vietnam. 相似文献

If the volatility is stochastic, stock price returns and European option prices depend on the time average of the variance, i.e. the integrated variance, not on the path of the volatility. Applying a Bayesian statistical approach, we compute a forward-looking estimate of this variance, an option-implied integrated variance. Simultaneously, we obtain estimates of the correlation coefficient between stock price and volatility shocks, and of the parameters of the volatility process. Due to the convexity of the Black–Scholes formula with respect to the volatility, pricing and hedging with Black–Scholes-type formulas and the implied volatility often lead to inaccuracies if the volatility is stochastic. Theoretically, this problem can be avoided by using Hull–White-type option pricing and hedging formulas and the integrated variance. We use the implied integrated variance and Hull–White-type formulas to hedge European options and certain volatility derivatives. 相似文献

Citizens tend to overestimate the electoral success of their preferred party. We investigate the extent to which Belgian voters overestimate the result of the party that they vote for and the factors that explain which voters do so more than others. Our focus is on the impact of educational attainment and partisan attachment on the overestimation of one’s party’s result. Previous research in this field has relied on data gathered in the months before the elections, which introduces a substantial amount of uncertainty and variation over time into the measurements of citizens’ vote share estimations. As an alternative, we investigate voters’ estimations of their party’s electoral success by means of data gathered in an exit poll survey. Our results show partisan attachments to have a strong impact on overestimations, which suggests that a wishful thinking mechanism is in play. Furthermore, we find that the extent to which partisan attachments increase citizens’ overestimations depends on a voter’s level of education. 相似文献
