Design Aspects of the VLBI2010 System - Progress Report of the IVS VLBI2010 Committee

This report summarizes the progress made in developing the next generation VLBI system, dubbed the VLBI2010 system. The VLBI2010 Committee of the International VLBI Service for Geodesy and Astrometry (IVS) worked on the design aspects of the new system. The report covers Monte Carlo simulations showing the impact of the new operating modes on the final products. A section on system considerations describes the implications for the VLBI2010 system parameters by considering the new modes and system-related issues such as sensitivity, antenna slew rate, delay measurement error. RF1, frequency requirements, antenna deformation, and source structure corrections_ This is followed by a description of all major subsystems and recommendations for the network, station. and antenna. Then aspects of the feed, polarization processing. calibration, digital back end, and correlator subsystems are covered. A section is dedicated to the NASA. proof-of-concept demonstration. Finally, sections tm operational considerations, on risks and fallback options, and on the next steps complete the report

Attitudes towards plants - exploring the role of plants' ecosystem services

With biodiversity loss as one of today's most pressing global problems, it is crucial to raise public recognition of this crisis and promote acceptance of conservation efforts. Plants, which typically struggle with low awareness ('plant blindness') and less emotional connection than animals with humans, are facing a special challenge. Promoting positive attitudes towards, and interest in, plants might provide the key to resolve this discrepancy. This study aims to differentiate attitudes and interest within the plant awareness framework while at the same time identify criteria for developing positive attitudes and interest towards plants in students. In a mixed-method approach, a questionnaire with closed and open items on attitudes and interest was developed and administered online to 179 students aged 9-19. Quantitative as well as qualitative results show that 'attitudes towards plants' can be differentiated from 'interest in plants'. Attitudes towards plants were positive, whereas interest in plants was rather low, with cultural and regulating ecosystem services acting as primary reasons for students' positive attitudes. These two components can be easily incorporated in botany teaching in order to promote plant awareness and increase knowledge about their crucial role in ecosystems and global climate, thus raising acceptance for conservation
