title: Mass-loading and parallel magnetized shocks

authors: Zank, Gary P.

subjects: MHD

abstract: Recent observations at comets Giacobini-Zinner and Halley suggest that simple non-reacting gas dynamics or MHD is an inappropriate description for the bow shock. The thickness of the observed (sub)shock implies that mass-loading is an important dynamical process within the shock itself, thereby requiring that the Rankine-Hugoniot conditions possess source terms. This leads to shocks with properties similar to those of combustion shocks. We consider parallel magnetized shocks subjected to mass-loading, describe some properties which distinguish them from classical MHD parallel shocks, and establish the existence of a new kind of MHD compound shock. These results will be of importance both to observations and numerical simulations of the comet-solar wind interaction.

title: Social interactions using an electronic rabbit

authors: Zaicu, Alexandru Calin

subjects: computer science

abstract: In this project we use an electronic rabbit called Karotz, created by French company Violet. The rabbits have the ability to connect autonomously to a WI-FI network. IN this project we use Karotz to record an audio log that will contain sounds of the environment. We also programmed a way for the rabbit to send audio to its other Karotz friend. We explored if Karotz can be used to help people stay in contact with each other and to feel less homesick.

title: Bizarre thoughts, magical ideations, and voices from the unconscious: Exploring issues of anomalous experience

authors: Tamatea, Armon J.

subjects: Maori

abstract: This project was initially concerned with the clinical interpretations of ‘bizarre’ or
‘magical’ ideations (i.e., statements considered to have little or no validity in our
predominant western culture). The first study explored clinical assessment issues
of who determines the validity of expressed beliefs and what kinds of criteria such
decisions are based on in the mental health field. The present study examined a
particular type of magical ideation, an auditory phenomenon involving claims that
forward spoken conversation contains hidden backwards speech embedded in the
vocal sounds. Thirty-two participants were invited to listen to various audio
samples of the alleged phenomenon and provide interpretations of what was heard.
Participants were assigned to four groups, each differing in the level of pre-emptive
information. A comparative measure revealed that priming and suggestion could
not be dismissed as alternative explanations of the reported effects. Clinical and
social implications will be discussed.
