Description: This study was undertaken to investigate the adaptation to long term waterlogging of semi-arid eucalyptus species. Long-term waterlogging of Eucalyptus victrix seedlings significantly increases seedling stem diameter. Flooding reduces photosynthesis, transpiration and stomatal conductance. Flooding does not increase shoot fresh or dry weight of 4-, 8- or 17- week old seedlings. Leaf emergence may be stimulated for flooded seedlings compared with unflooded seedlings. Root dry weight is not significantly greater for 17- week old flooded plants than 13- week old seedlings. We suggest that maintenance of a high root/shoot ratio is a drought adaptation. Furthermore, a comparative study of flood tolerance in semi-arid eucalypt species suggests that those species intolerant of flooding seldom express morphological adaptations and fail to recover from physiological damage. Flooding significantly reduced the transpiration rate and stomatal conduct of all three species. Diurnal transpiration, stomatal conductance and leaf water potential of E. terminalis and E. leucophloia were significantly different between treatment (flooding) and control seedlings.

Description: Networks, knowledge, and relationships have become crucial assets to business survival in the new economy. Research indicates that network building is a major new source of competitive advantage and an essential regional and indeed global management requirement. Because regional policies encourage interfirm alliances and the development of regional economic communities, the fostering of a culture of connectivity, networking, learning, and trust between regional Australian small and medium- size tourism enterprises (SMTEs) may offer a potential solution to the possible loss of competitive advantage for Australian tourism enterprises. It is suggested that SMTEs would benefit from increased information flow through regional networking and cooperative e-marketing campaigns to enhance market visibility, global positioning, and strategic leverage in the new economy.

Description: This study compared how extraversion, neuroticism, and extraversion × neuroticism are related to processing of pleasant and unpleasant emotional information as predicted by Eysenck's, Gray's, and Newman's theories. Initially, the participants' levels of extraversion (as measured by the sociability subscale) and neuroticism were assessed with Eysenck's Personality Inventory. They were then tested individually. After completing a questionnaire of current positive and negative moods, they completed three tasks measuring processing of pleasant, unpleasant, and also neutral information. The results showed that extraversion was associated positively with the processing of pleasant information, while neuroticism was associated positively with the processing of unpleasant information. These findings support predictions from Eysenck's theory. © 2002 John Wiley & Sons, Ltd.

Description: Opalescence is an unattractive browning of the interior of the pecan kernel compared to the white interior of normal kernels. The discoloration is due to the presence of free oil, resulting from decompartmentalization in the endosperm of opalescent pecans. Using a subjective scoring system, approximately 70% of Australian-grown pecan kernels tested were found to exhibit opalescence to some degree. Evaluation of kernels for opalescence during the harvesting-processing chain showed that opalescence first becomes evident in kernels after mechanical cracking. Opalescent kernels were found to have lower levels of calcium and higher amounts of oil compared to nonopalescent kernels. Differential scanning calorimetry showed that kernels do not freeze at -18°C.

Description: Advertising expenditure has risen globally and in Australia there has been a 2.7-fold rise in the last 10 years. It is suggested that some advertisements may be 'unacceptable', that is unfair, misleading, deceptive, offensive, false or socially irresponsible. Industry and regulatory responses to consumer complaints about these problems must be addressed. This research is concerned with consumer behaviour and consumer complaint behaviour specifically in the area of advertising in Australia. The general findings from the reviewed literature indicated that complainants tend to be older, have attained higher levels of educational qualifications, earn a higher gross weekly income, possess greater degrees of wealth, have higher participant levels of local community involvement and, in general terms, have more resources to avail themselves of in order to allow them to take action when dissatisfied. The results from this research engender a better understanding of the complaining public. Empirical analyses were used for determining the characteristics of people who complain to the Advertising Standards Board and inferred that their opinions regarding advertising differ from members of the general population in four key areas. This research will afford regulatory bodies a better understanding of the complaining public as well as educating marketing communications strategists in effectively reaching their target markets. © 2002 Taylor & Francis Ltd.

Description: Differential repetitive processes are a class of continuous-discrete 2D linear systems of both systems theoretic and applications interest. The feature which makes them distinct from other classes of such systems is the fact that information propagation in one of the two independent directions only occurs over a finite interval. Applications areas include iterative learning control and iterative solution algorithms for classes of dynamic nonlinear optimal control problems based on the maximum principle. In this paper, we first develop new results on optimal and sub-optimal control for an important sub-class of differential linear repetitive processes and then proceed to extend the well known maximum and -maximum principles to this sub-class. The end goal of the research programme for which this paper forms part of the output is the development of numerically reliable algorithms for the synthesis of optimization based control schemes for these processes.

Description: In this article, we study the nonlinear penalization of a constrained optimization problem and show that the least exact penalty parameter of an equivalent parametric optimization problem can be diminished. We apply the theory of increasing positively homogeneous (IPH) functions so as to derive a simple formula for computing the least exact penalty parameter for the classical penalty function through perturbation function. We establish that various equivalent parametric reformulations of constrained optimization problems lead to reduction of exact penalty parameters. To construct a Lipschitz penalty function with a small exact penalty parameter for a Lipschitz programming problem, we make a transformation to the objective function by virtue of an increasing concave function. We present results of numerical experiments, which demonstrate that the Lipschitz penalty function with a small penalty parameter is more suitable for solving some nonconvex constrained problems than the classical penalty function.

Description: This study examined the relationships of the traits associated with Gray's behavioral approach system (BAS) and behavioural inhibition system (BIS) with cognitive processing of emotional information. Initially, participants completed questionnaires covering trait impulsivity and anxiety, and BAS and BIS sensitivities. They were then tested individually. After completing a questionnaire of current positive and negative moods, they completed three tasks measuring processing of pleasant, unpleasant and neutral information. Consistent with Gray's theory, the results showed that impulsivity and BAS sensitivity were associated with the processing of pleasant information, while anxiety and BIS sensitivity were associated with the processing of unpleasant information. These findings imply that Gray's BAS-BIS theory can be extended to cognitive processing of emotional information. © 2002 Elsevier Science Ltd. All rights reserved.

Description: Phenological observations of eucalypts (Myrtaceae) were undertaken in four Australian states (New South Wales, Queensland, Victoria, and Western Australia) from the late 1920s until the early 1980s, by the respective State Forest Commissions. Unfortunately, few records have survived. For Victoria, surviving records encompass 42 forest districts, covering from less than 2 years to 42 years, and approximately 50 species. This paper concentrates on the flowering of four competing species (Eucalyptus leucoxylon, E. microcarpa, E. polyanthemos, and E. tricarpa) over 23 years (1940-62) from Maryborough, Victoria, recorded on a monthly basis by one observer over the period. This study represents one of the first attempts to utilize Australian phenological data to detect responses to climate change. There were no significant trends (P = 0.05) over time in the mean flowering commencement date. Forward stepwise regression found a significant relationship between temperature and flowering commencement in two species (E. leucoxylon: R-2 = 0.42, P < 0.01; E. polyanthemos: R-2 = 0.47, P = 0.02). Rainfall also had a significant influence on flowering commencement in E. tricarpa (R-2 = 0.60, P < 0.01), E. leucoxylon (R-2 = 0.43, P = 0.02) and E. polyanthemos (R-2 = 0.24, P < 0.01). The combination of temperature and rainfall (with temperature exerting the greatest influence), however, was significant for all species and had the most explanatory power (ranging from R-2 = 0.74 to 0.85, P < 0.01). Overall, in response to predicted increases in temperature and summer rainfall, E. leucoxylon and E. tricarpa would commence flowering later. In E. polyanthemos and E. microcarpa, increased temperature and rainfall will result in an earlier onset of flowering. Copyright (C) 2002 Royal Meteorological Society.

Description: There is a fundamental spatial mismatch in the data available for modeling human population from satellite imagery. Spectral reflectances are available for each pixel of an image, but ground reference population data are available only for larger zones. The general response has been to build models for the average population density of the zones, utilizing spatially aggregated spectral data. This approach has limitations, both for the modeling process and for the utilization of the resulting spatially aggregated population estimates. A pixel-based alternative is described. Pixels of a Landsat TM image were classified as residential or non-residential using standard techniques. Initial reference populations were assigned by uniformly distributing the population of each zone across its residential pixels. An expectation-maximization (EM) algorithm was used to iteratively regress pixel population on spectral indicators and re-estimate pixel populations. Predictive validity was tested by applying the fitted regression equation to a second image. The pixel-based model produced population estimates of comparable accuracy to those resulting from a much more complex zone-based modeling procedure. The pixel-based procedure was also more robust and more amenable to refinement, particularly at the extremes of population density. The relative error in the estimated total urban population of both primary and secondary study areas was less than 1 percent. Median relative error in the population of individual zones was 16 percent in the primary study area (14 percent for urban zones) and 21 percent in the secondary study area (17 percent for urban zones).

Description: Depression following childbirth is a common, distressing but frequently underreported disorder. It involves a spectrum of symptoms, some of which may be self-limiting, while others can have major mental health implications in the post partum period. A range of health professionals, including midwives and mental health nurses, come into contact with women who suffer from postnatal depression; however, there is often little attempt made to integrate maternity and mental health care approaches. More collaborative frameworks of care are vital if health professionals are to adequately meet the needs of 'unhappy' women in the postnatal period.
