MarathOn Multiscreen: group television watching and interaction in a viewing ecology

This paper reports and discusses the findings of an exploratory study into collaborative user practice with a multiscreen television application. MarathOn Multiscreen allows users to view, share and curate amateur and professional video footage of a community marathon event. Our investigations focused on collaborative sharing practices across different viewing activities and devices, the roles taken by different devices in a viewing ecology, and observations on how users consume professional and amateur content. Our Work uncovers significant differences in user behaviour and collaboration when engaged in more participatory viewing activities, such as sorting and ranking footage, which has implications for awareness of other users’ interactions while viewing together and alone. In addition, user appreciation and use of amateur video content is dependent not only on quality and activity but their personal involvement in the contents

In Whose Backyard?: Concern About Sitting a Nuclear Waste Facility

Proponents of hazardous and nuclear waste depositories label opponents to local siting of such facilities NIMBYs (Not In My Backyard). This study assesses the extent to which the NIMBY label and the strategies of industry proponents to reduce opposition function on a reasonable set of assumptions. Using survey data and multiple regression techniques, the levels of concern of residents living in the county selected as the site of a low level radioactive wane disposal facility (imminent threat condition) are compared with a statewide sample (hypothetical threat condition). Consistent with proponents\u27 theoretical assumptions, the levels of concern are greater for respondents under conditions of imminent threat than of hypothetical threat. However, within the host county, levels of concern are lowest, albeit most polarized, in the community closest to the proposed site. A conflict theory approach enhances an understanding of these findings by suggesting that within the most proximate community levels of concern are lowest for citizens who stand to gain the most economic benefits from the facility but highest for those citizens who are least likely to derive tangible gains

Many-screen viewing: evaluating an olympics companion application

The trend of users integrating second screen behaviours in their viewing habits, and practitioners’ interest in designing systems to support them has evolved a strong research agenda. In this paper we extend these ideas to explore many-screen interaction, investigating how users, gathered around the television with multiple second screen devices, share, control and coordinate their interactions. We report on a formative evaluation into behaviours with a many-screen prototype app for watching sport programming. The Olympics Second Screen application allows users to watch, share and control highlight programmes in a collocated group. We discuss our findings through recommendations to designers and HCI practitioners. Our results suggest the importance of supporting parallel viewing between collocated viewers, and sharing and queuing of programming between devices. Additionally, results highlight the significance of the television in a viewing ecology, and user awareness of control and interaction

Quark Masses: An Environmental Impact Statement

We investigate worlds that lie on a slice through the parameter space of the Standard Model over which quark masses vary. We allow as many as three quarks to participate in nuclei, while fixing the mass of the electron and the average mass of the lightest baryon flavor multiplet. We classify as "congenial" worlds that satisfy the environmental constraint that the quark masses allow for stable nuclei with charges one, six, and eight, making organic chemistry possible. Whether a congenial world actually produces observers depends on a multitude of historical contingencies, beginning with primordial nucleosynthesis, which we do not explore. Such constraints may be independently superimposed on our results. Environmental constraints such as the ones we study may be combined with information about the a priori distribution of quark masses over the landscape of possible universes to determine whether the measured values of the quark masses are determined environmentally, but our analysis is independent of such an anthropic approach. We estimate baryon masses as functions of quark masses and nuclear masses as functions of baryon masses. We check for the stability of nuclei against fission, strong particle emission, and weak nucleon emission. For two light quarks with charges 2/3 and -1/3, we find a band of congeniality roughly 29 MeV wide in their mass difference. We also find another, less robust region of congeniality with one light, charge -1/3 quark, and two heavier, approximately degenerate charge -1/3 and 2/3 quarks. No other assignment of light quark charges yields congenial worlds with two baryons participating in nuclei. We identify and discuss the region in quark-mass space where nuclei would be made from three or more baryon species.Comment: 40 pages, 16 figures (in color), 4 tables.

Natural Wormholes as Gravitational Lenses

Visser has suggested traversable 3-dimensional wormholes that could plausibly form naturally during Big Bang inflation. A wormhole mouth embedded in high mass density might accrete mass, giving the other mouth a net *negative* mass of unusual gravitational properties. The lensing of such a gravitationally negative anomalous compact halo object (GNACHO) will enhance background stars with a time profile that is observable and qualitatively different from that recently observed for massive compact halo objects (MACHOs) of positive mass. We recommend that MACHO search data be analyzed for GNACHOs.Comment: 4 pages; plus 4 figures; ReV_TeX 3.0; DOE/ER/40537-001/NPL94-07-01
