Trusting to Learn: Trust and Privacy Issues in Serious Games
Organizations are increasingly investing in technology-enhanced learning systems to improve their employees’ skills. Serious games are one example; the competitive and fun nature of games is supposed to motivate employee participation. But any system that records employee data raises issues of privacy and trust. In this paper, we present a study on privacy and trust implications of serious games in an organizational context. We present findings from 32 interviews with potential end-users of a serious games platform called TARGET. A qualitative analysis of the interviews reveals that participants anticipate privacy risks for the data generated in game playing, and their decision to trust their fellow employees and managers depends on the presence of specific trust signals. Failure to minimize privacy risks and maximize trust will affect the acceptance of the system and the learning experience – thus undermining the primary purpose for which it was deployed. Game designers are advised to provide mechanisms for selective disclosure of data by players, and organizations should not use gaming data for appraisal or selection purposes, and clearly communicate this to employees
ALMA observations of a z ≈ 3.1 protocluster: star formation from active galactic nuclei and Lyman-alpha blobs in an overdense environment
We exploit Atacama Large Interferometer Array (ALMA) 870 μm observations to measure the star formation rates (SFRs) of eight X-ray detected active galactic nuclei (AGNs) in a z ≈ 3.1 protocluster, four of which reside in extended Lyα haloes (often termed Lyman-alpha blobs: LABs). Three of the AGNs are detected by ALMA and have implied SFRs of ≈220–410 M⊙ yr−1; the non-detection of the other five AGNs places SFR upper limits of ≲210 M⊙ yr−1. The mean SFR of the protocluster AGNs (≈110–210 M⊙ yr−1) is consistent (within a factor of ≈0.7–2.3) with that found for co-eval AGNs in the field, implying that the galaxy growth is not significantly accelerated in these systems. However, when also considering ALMA data from the literature, we find evidence for elevated mean SFRs (up-to a factor of ≈5.9 over the field) for AGNs at the protocluster core, indicating that galaxy growth is significantly accelerated in the central regions of the protocluster. We also show that all of the four protocluster LABs are associated with an ALMA counterpart within the extent of their Lyα emission. The SFRs of the ALMA sources within the LABs (≈150–410 M⊙ yr−1) are consistent with those expected for co-eval massive star-forming galaxies in the field. Furthermore, the two giant LABs (with physical extents of ≳100 kpc) do not host more luminous star formation than the smaller LABs, despite being an order of magnitude brighter in Lyα emission. We use these results to discuss star formation as the power source of LABs
