ABSTRACT
This paper presents the GLOBALINTO Input-Output Intangibles Database, that was constructed in the context of the Horizon2020 project 'GLOBALINTO: Capturing the value of intangible assets in micro data to promote the EU's Growth and Competitiveness'. The database is formulated under an input-output framework and treats intangibles as producer services that derive from certain knowledge producing sectors in the economy (namely J62-J63 - Computer programming, consultancy, and related activities; Information service activities, M72 - Scientific research and development, M73 - Advertising and market research, and N - Administrative and support service activities) and embeds them withing the context of global value chains (GVCs) as traded knowledge intermediates. Data include intangibles related variables for 56 2-digit NACE Rev. 2/ ISIC Rev. 4 sectors from the EU-27 and the UK and are complemented with export variables and R&D related statistics from Eurostat for the period 2000-2014. An application of the dataset can be found in the research article 'Intangibles, innovation, and sector specialization in global value chains: A case study on the EU's and the UK's manufacturing industries' [1] .
ABSTRACT
The chemical composition of the essential oils isolated from various parts of three Greek aromatic plants (Lavandula hybrida Rev, Rosmarinus officinalis L and Eucalyptus globulus Labill) collected at different seasons was determined by GC/MS analysis. The insecticidal action of these oils and of their main constituents on Acanthoscelides obtectus (Say) adults was evaluated and their LC50 values were estimated. All essential oils tested exhibited strong activity against A. obtectus adults, with varying LC50 values depending on insect sex and the composition of the essential oils. A correlation between total oxygenated monoterpenoid content and activity was observed, with oxygenated compounds exhibiting higher activity than hydrocarbons. Among the main constituents, only linalyl and terpinyl acetate were not active against A. obtectus, while all the others exhibited insecticidal activity against both male and female adults, with LC50 values ranging from 0.8 to 47.1 mg litre(-1) air. An attempt to correlate the insecticidal activity to the monoterpenoid's structure is presented, and the difference in sensitivity between male and female individuals is also explored.
