A scalarization technique for computing the power and exponential moments of gaussian random matrices

We consider the problems of computing the power and exponential moments EXs and EetX of square Gaussian random matrices X=A+BWC for positive integer s and real t, where W is a standard normal random vector and A, B, C are appropriately dimensioned constant matrices. We solve the problems by a matrix product scalarization technique and interpret the solutions in system-theoretic terms. The results of the paper are applicable to Bayesian prediction in multivariate autoregressive time series and mean-reverting diffusion processes.

Dominance hierarchies and health: Constructing personal zones of spiritual power and healing in modern medicine

Ethological studies of animals in groups and sociobiology indicate that hierarchies of dominance amongst some species ensure the survival of the group. When transferred to human groups, dominance hierarchies suggest a crucial role played by recasting the scope of such hierarchies of dominant and subordinate members to included hyper-dominant beings. A recognition of such beings as even more dominant than the socially dominant members of a hierarchy facilitates the empowerment of the socially subordinate members. Religious belief and practice works to establish such hyper-dominant beings (gods, goddesses, and so forth) as superior members of human groups. Doing so is a means of ensuring the survival of the species and, thus, enhancing healing and human health. The doctor-patient relationship is examined from such a point of view, with an emphasis on whether the hierarchy created by the relationship allows consideration of alternative and complementary forms of medical treatment.

Group membership, power and social rules: A study of doctor-nurse relationship

The purposes of this research are: (1) to compare the similarides and differences in intra-group and inter-group social rules of hospital doctors and nurses; (2) to compare rule following, rule breaking & tolerance of rule breaking of doctors and nurses with respect to different work reladonships. Professional discipline and idendficadon, ingroup-outgroup membership and reladve status were used as predictors. In-depth interview of 20 doctors and 20 nurses were conducted to elicit social rules and goals. In the second study, 30 rules and 10 goals with high consensus were selected from study one and developed into a quesdonnaire which measured their applicadon to four different work reladonships, namely, padents, peers, seniors and doctors/nurses. Forty-three doctors and one hundred and seven nurses completed this questionnaire. In the third study, the frequency and goals of violation and tolerance of violation of five different social rules were measured. One hundred and thirty-six doctors and one hundred and sixty-six nurses completed the questionnaire.

UQ RoboRoos: Achieving power and agility in a small size robot

The UQ RoboRoos have been developed to participate in the RoboCup robot soccer small size league over several years. RoboCup 2001 saw a focus on the mechanical design of the RoboRoos, with the introduction of an omni-directional drive system and a high power kicker. The change in mechanical design had implications for the rest of the system particularly navigation and multi-robot planning. In addition, the overhead vision system was upgraded to improve reliability and robustness.

Outsourcing and inter-intra supply chain dynamics: Strategic management issues

This article analyzes the outsourcing of information technology services, using an action inquiry methodology. Research spanned the disengagement and beginning of IT service functions transferred from work groups in the parent company to outsource teams. Results identified the importance of addressing strategic issues and inter/intra relationships between parent company team members and their outsource-counterparts. Conclusions indicate that behavioral issues such as psychological contracts within inter/intra work groups, power and trust are highly significant managerial issues in the success or failure of an outsourcing strategy.
