In this paper, a new method is presented to derive an input–output table from a system of make and use tables. The method, which we call ‘activity technology’, is mathematically equivalent to the well-known commodity technology, but chooses another unit, i.e. the activity. We will argue that, in the activity technology model, negatives can only arise from causes such as heterogeneity and errors in the data. To apply the activity technology, very detailed make and use matrices are required, as well as additional data on the input structures of certain activities. We will describe a method that can incorporate this additional data within the activity technology framework. Statistics Netherlands has adopted the method  相似文献

Anthropogenic climate change is increasing the frequency and severity of extreme weather events (e.g. flooding, heat waves, and wildfires). As a result, it is often reasoned that as more individuals experience unusual weather patterns that are consistent with changing climate conditions, the more their concern about global warming will increase, and the more motivated they will become to respond and address the problem effectively. Social science research evaluating the relationships between personal experiences with and risk perceptions of climate change, however, show mixed results. Here, we analyze a representative statewide survey of Floridians and compare their risk perceptions of five-year trends in climate change with local weather station data from the five years preceding the survey. The results show that Floridians are unable to detect five-year increases in temperature, but some can detect changes in precipitation. Despite an inability to detect the correct direction of change, respondents were significantly more likely than not to correctly identify the season in which most change occurred. Nevertheless, compared to local experience, risk perceptions of climate change were more strongly predicted by subjective experiences of environmental change, personal beliefs about climate change, and political ideology. Results from the study suggest that long-term changes in climate patterns and extreme weather events need to be interpreted by weather and climate experts within the context of climate change; individuals cannot be expected to detect or comprehend such complex linkages directly.  相似文献

Agri-environmental schemes (AESs) are increasingly implemented to promote the adoption of environmentally friendly practices by farmers. We use a systematic review to explore the role of behavioural factors and opportunity costs in farmers' decisions to participate in AESs in Australia, Europe and North America. Behavioural factors influence how farmers value and perceive options, while opportunity costs relate to farmers' forgone utility when choosing to participate in schemes. We synthesise insights from 79 articles and over 700 factors explaining the participation in AESs. We find that a set of behavioural factors seem consistently connected to participation, including agricultural training, advice and having positive attitudes towards AESs. Moreover, several factors related to opportunity costs also have a rather consistent relationship with AES participation, including market conditions, implementation efforts, profitability, and management and contract flexibility. However, many relationships of behavioural factors and opportunity costs with AES participation are not as consistent and generalizable as sometimes portrayed and require context-specific interpretation. Those factors with mixed results can still provide insights into farmers' participation decisions as several of them are either ‘positively and insignificantly’ or ‘negatively and insignificantly’ related to participation, such as environmental attitude, trust and farm size. These results suggest that their relationship with AES participation depends on other factors or the setting, highlighting interactions and raising important new research questions. Overall, our results provide several entry points for both researchers and policy-makers, highlighting uncertainties in relationships between factors and participation that should be considered when designing policies.  相似文献

Comparing companies can be useful for various purposes. Despite the widespread use of industry classification systems as a peer selection standard, these have been criticized for various reasons. Financial statements, however, offer a promising alternative to such classification systems. They are standardized, widely available, and offer deep insights into the nature of the company. In this paper, we present a graph distance metric for financial statements using the earth mover's distance. When using the distance metric on real-world tasks such as peer identification and industry classification, it shows promising results in terms of accuracy and computational efficiency.  相似文献

The EU has proposed a voluntary framework for certification of carbon removals which remains vague on blue carbon and in particular, carbon removal through use of seaweeds. Seaweed is considered an emerging blue carbon option. Various studies have confirmed the potential of seaweed to contribute to long-term carbon removal, storing it away from the atmosphere for 100 years and more. Certification of seaweed carbon sequestration is promoted, even in other EU communications. This article reviews early experiences with certification of carbon and nutrient removal by aquaculture using the QU.A.L.ITY criteria proposed by the EU. Examples reviewed include the Seaweed Company, Venice Bay, Yokohama Bayside marine, and Chesapeake Bay in the USA. After reviewing these examples, we call on the European Commission to move forward towards certification of blue carbon. If the EU is to lead global climate mitigation efforts, including carbon removal, it should take seaweed blue carbon seriously and include it in its voluntary framework. To enhance the awareness of the relevance and the acceptance of the carbon credits from seaweed, a methodology has to be developed that, building on experiences gained, deals with inherent uncertainties.  相似文献
