Marketing and branding for non-profit organisations: A case for mathematics for a lifetime.

This research aspires to discuss and analyse the current system of recruiting and retaining volunteers in the events industry, and a comparison with the volunteer programme model existing in H3 Group. The method chosen for this research is qualitative, as the research includes interviews. In order to get a better understanding, interviews are going to be held with people who are part of the industry and have extensive knowledge of this matter. In addition, with the purpose knowing another perspective, two people will be interviewed who habitually participate in activities as volunteers for H3 Group, specifically for sports events in FMG Stadium. The results obtained basically indicate that there is a difference between the information given by the person in charge of the volunteer program of H3 Group, and the perception that the volunteers had about their personal experience of volunteering for the matches held by the Rugby League World Cup in November last year. The difference occurs mainly because according to the information provided by H3 Group, the volunteer programme includes a whole complete process, and the staff is always making sure that the volunteers feel comfortable and confident about what are they tasks. On the other hand, the volunteers think that the assigned task was not of great importance and that many times they got bored because they had nothing to do. Also, they did not receive any feedback on their performance, so they were not sure if what they did was good or not

Condition for low-mass star formation in shock-compressed metal-poor clouds

Shocks may have been prevalent in the early Universe, associated with virialization and supernova explosions, etc. Here, we study thermal evolution and fragmentation of shock-compressed clouds, by using a one-zone model with detailed thermal and chemical processes. We explore a large range of initial density (1-1e5 /cm^3), metallicity (0-1e-2 Z_sun), UV strength (0-500 times Galactic value), and cosmic microwave background temperature (10 and 30 K). Shock-compressed clouds contract isobarically via atomic and molecular line cooling, until self-gravitating clumps are formed by fragmentation. If the metals are only in the gas-phase, the clump mass is higher than ~ 3 M_sun in any conditions we studied. Although in some cases with a metallicity higher than ~ 1e-3 Z_sun, re-fragmentation of a clump is caused by metal-line cooling, this fragment mass is higher than ~ 30 M_sun. On the other hand, if about half the mass of metals is condensed in dust grains, as in the Galactic interstellar medium, dust cooling triggers re-fragmentation of a clump into sub-solar mass pieces, for metallicities higher than ~ 1e-5 Z_sun. Therefore, the presence of dust is essential in low-mass (< M_sun) star formation from a shock-compressed cloud.Comment: 15 pages, 8 figures, accepted for publication in MNRA
