Automatic detection of potentially illegal online sales of elephant ivory via data mining
No full textIn this work, we developed an automated system to detect potentially illegal elephant ivory items for sale on eBay. Two law enforcement experts, with specific knowledge of elephant ivory identification, manually classified items on sale in the Antiques section of eBay UK over an 8 week period. This set the “Gold Standard” that we aim to emulate using data-mining. We achieved close to 93% accuracy with less data than the experts, as we relied entirely on metadata, but did not employ item descriptions or associated images, thus proving the potential and generality of our approach. The reported accuracy may be improved with the addition of text mining techniques for the analysis of the item description, and by applying image classification for the detection of Schreger lines, indicative of elephant ivory. However, any solution relying on images or text description could not be employed on other wildlife illegal markets where pictures can be missing or misleading and text absent (e.g., Instagram). In our setting, we gave human experts all available information while only using minimal information for our analysis. Despite this, we succeeded at achieving a very high accuracy. This work is an important first step in speeding up the laborious, tedious and expensive task of expert discovery of illegal trade over the internet. It will also allow for faster reporting to law enforcement and better accountability. We hope this will also contribute to reducing poaching, by making this illegal trade harder and riskier for those involved
Incentive policies and agricultural performance in sub-Saharan Africa
No full textExports in general, and agricultural exports in particular, are more responsive to price incentives in Sub-Saharan Africa than in developing countries.. These are the results of an econometric investigation on the effects of real exchange rates on exports. It further appears that in Sub-Saharan Africa the impact of real exchange rates is greater on agricultural exports than on the exports of goods and services. Within Sub-Saharan Africa, market-oriented countries generally gained export market shares while interventionist countries lost shares. This occurred when market-oriented, not interventionist countries, maintained realistic exchange rates and did not bias incentives against exports. For example, Kenya and the Ivory Coast exemplify market-oriented, and Tanzania and Ghana interventionist, countries. Pairwise comparisons between the Ivory Coast and Ghana have indicated the superiority of the market-oriented approach in promoting exports and agricultural production.Economic Theory&Research,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,Export Competitiveness,Environmental Economics&Policies,Access to Markets
