A Simple Model for Understanding the DIM Dust Measurement at Comet 67P/Churyumov-Gerasimenko

We present a simple model for gas and dust flow from 67P/Churyumov-Gerasimenko that can be used to understand the grain impact observed by the DIM instrument on Philae (Krueger et al. 2015) We show how model results when applied to the GIADA measurements (Rotundi et al. 2015; Della Corte et al. 2015) can be used, in conjunction with the results found by the MIRO (Schloerb et al. 2015) and VIRTIS (De Sanctis et al. 2015) instruments to infer surface properties such as surface temperature and surface ice fraction.Comment: 15 pages, 4 figures.

Stakeholder engagement via facebook. An analysis of world’s most popular museums

Over the last few years, social media (SM) have been emphasised as a means for organisations to foster stakeholder relationship with particular stress on their potential to promote community building and dialogic engagement with online audiences. These potential benefits of SM have been claimed also with respect to cultural organisations. However, the available research evidence on SM and museums suggests that museums still struggle to exploit these tools to their full potential. This paper adds further evidence on this issue by empirically investigating whether museums are using Facebook to promote follower engagement using a sample of top-attended museums worldwide. Results suggest that the frequency and content type of posts correlate to some extent with the degree of follower reactions. Nevertheless, sample museums predominantly use SM to publish promotional contents and as a result fail to achieve a true ‘dialogic’ follower engagement

Digitalization and firm financial performance in healthcare: the mediating role of intellectual capital efficiency

The digitalization of processes in healthcare sector firms is expected to reduce costs, improve the quality of healthcare service, customer care experience, and patient safety, and attain efficiency and efficacy in project implementation. This research investigates the impact of digitalization on the financial performance of healthcare-sector firms in the European Union. The study also examines whether a firm’s intellectual capital efficiency mediates the process of digitalization’s impact on a firm’s financial performance. Using a sample of 965 firm observations from 2017 to 2021, we find that digitalization positively affects financial performance. Further analysis suggests that capital-employed efficiency fully mediates the relationship between digitalization and firm performance. Partial mediation is also reported for intellectual capital efficiency, human capital efficiency, and structural capital efficiency in the process of digitalization impacting firm performance. These findings provide fresh insight into how digitalization impacts a firm’s financial performance, establishing intellectual capital efficiency as a mediating mechanism that may explain this impact

The SSDC contribution to the improvement of knowledge by means of 3D data projections of minor bodies

The latest developments of planetary exploration missions devoted to minor bodies required new solutions to correctly visualize and analyse data acquired over irregularly shaped bodies. ASI Space Science Data Center (SSDC-ASI, formerly ASDC-ASI Science Data Center) worked on this task since early 2013, when started developing the web tool MATISSE (Multi-purpose Advanced Tool for the Instruments of the Solar System Exploration) mainly focused on the Rosetta/ESA space mission data. In order to visualize very high-resolution shape models, MATISSE uses a Python module (vtpMaker), which can also be launched as a stand-alone command-line software. MATISSE and vtpMaker are part of the SSDC contribution to the new challenges imposed by the "orbital exploration" of minor bodies: 1) MATISSE allows to search for specific observations inside datasets and then analyse them in parallel, providing high-level outputs; 2) the 3D capabilities of both tools are critical in inferring information otherwise difficult to retrieve for non-spherical targets and, as in the case for the GIADA instrument onboard Rosetta, to visualize data related to the coma. New tasks and features adding valuable capabilities to the minor bodies SSDC tools are planned for the near future thanks to new collaborations
