Standard and Generalized Newtonian Gravities as ``Gauge'' Theories of the Extended Galilei Group - I: The Standard Theory

Newton's standard theory of gravitation is reformulated as a {\it gauge} theory of the {\it extended} Galilei Group. The Action principle is obtained by matching the {\it gauge} technique and a suitable limiting procedure from the ADM-De Witt action of general relativity coupled to a relativistic mass-point.Comment: 51 pages , compress, uuencode LaTex fil

The fruits of collaboration in a multidisciplinary field

Collaboration between researchers and between research organizations is generally considered a desirable course of action, in particular by some funding bodies. However, collaboration within a multidisciplinary community, such as the Computer–Human Interaction (CHI) community, can be challenging. We performed a bibliometric analysis of the CHI conference proceedings to determine if papers that have authors from different organization or countries receive more citations than papers that are authored by members of the same organization. There was no significant difference between these three groups, indicating that there is no advantage for collaboration in terms of citation frequency. Furthermore, we tested if papers written by authors from different organizations or countries receive more best paper awards or at least award nominations. Papers from only one organization received significantly fewer nominations than collaborative papers

Bridging the Gap

Bridging The Gap discusses necessities and methods of a transdisciplinary approach at the intersection of art, science and technology, including human computer interaction (HCI) and its various subjects. Research work that combines artistic and scientific approaches benefits substantially from artistic perception and the sensibility to questions beyond their regular environment beyond the work’s associated environment. The transfer of knowledge, methods and communication strategies foster a transdisciplinary debate, discussing impacts of existing and emerging technology driven phenomenons. The paper provides a depiction of methods and communication of each discipline to carve out the coherence of transdisciplinarity in praxis. F-A-S-T is introduced as a cooperative project of scientific and artistic institutions where a student’s existing profession is amplified by complementary knowledge, methods and collaborative project oriented work. It explores new roles and formats within the interaction between art, science and technology. The aim of the paper is to encourage further research regarding transdisciplinarity and the establishment of corresponding educational programs
