title: Magnetic reconnection in incompressible fluids

authors: DeLuca, Edward E.

abstract: We investigate the dynamical relaxation of a disturbed X-type magnetic neutral point in a periodic geometry, with an ignorable coordinate, for an incompressible fluid. We find that the properties of the current sheet cannot be understood in terms of steady state reconnection theory or more recent linear dynamical solutions. Accordingly we present a new scaling law for magnetic reconnection consistent with fast energy dissipation, i.e., the dissipation rate at current maximum is approximately independent of magnetic diffusivity (η). The flux annihilation rate, however, scales as η1/4, faster than the Sweet-Parker rate of η1/2 but asymptotically much slower than the dissipation rate. These results suggest a flux pile-up regime in which the bulk of the free magnetic energy is released as heat rather than as kinetic energy of mass motion. The implications of our results for reconnection in the solar atmosphere and interior are discussed.

title: Design and Evaluation of a Mobile Photo Gallery in TIP

authors: Wang, Yi

subjects: mobile photo gallery

abstract: As a part of the Tourist Information Provider (TIP) system, this project focuses on creating a photo gallery service in the TIP system, which allows users to share, browse and categorize their photos. The core of this project is to provide users a location-based photo browsing. The system provides photos which are taken in the current user's location. We considered privacy control on photos that users uploaded. A photo owner is able to sign an access level to each of their photos and permit different users to access them.
We also considered reusing resources. The system allows a user to use an URL of a photo in the system in stead of uploading the photo from the local computer. The system also provides a URL of each photo in order to use the photo on other web places, e.g., Blogs. We use tags and photo metadata Eixf to categorize photos.

title: Māori men, relationships, and everyday practices: towards broadening domestic violence research

authors: King, Pita

subjects: Māori

abstract: Relationships are central to the health and wellbeing of Māori (indigenous people of New Zealand). Through processes of colonisation, cultural ways of relatedness embedded within Māori social structures experienced disruption and were reshaped over decades of assimilation. Māori knowledge and everyday practices that assisted in protecting Māori from societal problems, such as domestic violence, began to dwindle. In contemporary New Zealand, Māori are over-represented in domestic violence statistics. Utilising an auto-ethnographic approach and case studies, our research focuses on five Māori men’s experiences within intimate relationships and whānau (extended family) life. A significant feature of this research is that it provides insights into the ways Māori men draw on their cultural ways-of-being to enhance intimate relationships and maintain bonds within whānau and community life to forge new ways-of-being. Such insights have the potential to inform preventative measures against domestic violence within Māori communities.
