The patrol officers and Tom Kabu: power and prestige in the Purari Delta

In 1946, Tom Kabu returned to the Gulf of Papua determined to reinvent the communities of the Purari Delta. A man of quiet determination, in the first few years he and his followers resisted the assistance of the Australian Administration in Palma and New Guinea. Kabu's popularity in the villages of the Purari, coupled with his independent stance, caused resentment within the local expatriate community. The field staff working for the Department of District Services and Native Affairs especially felt threatened by Kabu's influence and sought to regain government control by opposing his ventures. Through the study of patrol reports written by these officers, this paper seeks to examine the reasons for this resentment and the methods employed by the officers to crush Kabu's company.

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.

Ramp and constant power trials produce equivalent critical power estimates

The standard critical power test protocol on the cycle prescribes a series of trials to exhaustion, each at a different but constant power setting. Recently the protocol has been modified and applied to a series of trials to exhaustion each at a different ramp incremental rate. This study was undertaken to compare critical power and anaerobic work capacity estimates in the same group of subjects when derived from the two protocols. Ten male subjects of mixed athletic ability cycled to exhaustion on eight occasions in randomized order over a 3-wk period. Four trials were performed at differing constant power settings and four trials on differing ramp incremental rates. Both critical power and anaerobic work capacity were estimated for each subject by curve fitting of the ramp model and of three versions of the constant power model. After adjusting for inter-subject variability, no significant differences were detected between critical power estimates or between anaerobic work capacity estimates from any model formulation or from the two protocols. It is concluded that both the ramp and constant power protocols produce equivalent estimates for critical power and anaerobic work capacity.

Relations between high and low power groups: The importance of legitimacy

Using a social identity perspective, two experiments examined the effects of power and the legitimacy of power differentials on intergroup bias. In Experiment 1, 125 math-science students were led to believe that they had high or low representation in a university decision-making body relative to social-science students and that this power position was either legitimate or illegitimate. Power did not have an independent effect on bias; rather, members of both high and low power groups showed more bias when the power hierarchy was illegitimate than when it was legitimate. This effect was replicated in Experiment 2 (N =105). In addition, Experiment 2 showed that groups located within an unfair power hierarchy expected the superordinate power body to be more discriminatory than did those who had legitimately high or low power. The results are discussed in terms of their implications for group relations.
