    The primary objectives of this study were to understand how canopy cover and nest temperatures affect hatchling sex ratios and locomotor performance (i.e., swimming sprint speed and righting response) of Chrysemys picta marginata nests. Seventeen nests were monitored with temperature data-loggers during the 2009 nesting season and found to contain 100% male-biased clutches with a mean nest temperature range of 20.0–24.0°C during the thermosensitive period (TSP). The percentage of canopy cover over each nest was inversely and significantly correlated with mean nest temperatures experienced during the TSP. Mean nest temperatures (MNT) did not have a statistical effect on either measure of locomotor performance; however, there was an observed trend toward increased performance with increased MNT

    The structuration of brain dominance on organizational communication : a correlational study

    The purpose of this study was to examine if the influence of brain dominance as defined by Herrmann (1982, 1995), which includes left-brain/right-brain dominance and cerebral/ limbic dominance, offers predictive capabilities in determining preferences for communication channel selection, feedback frequency, and job satisfaction in organizations. The study also examined whether sex has a determining role in predicting preferences for communication channels, feedback, and job satisfaction. Raw scores from the Herrmann Brain Dominance Instrument (HBDI) were correlated with responses to a validated survey instrument, which combined items from the International Communication Association (ICA) Audit (Downs, 1988), and the Communication Satisfaction Questionnaire (CSQ) (Downs & Hazen, 1977). Participants were volunteers from four separate organizations who had taken the HBDI as part of a series of workshop seminars on whole brain thinking. Of the 210 participants, 108 were male and 102 were female. Insights into communication patterns in organizations were provided by Structuration Theory (Giddens, 1984), which proposes that social systems are produced and reproduced through daily communication interaction. The patterns that arise from the contradictions and tensions of daily interaction across time and space become real to us as institutions or organizations. Eleven hypotheses were tested using pairwise comparisons. Three hypotheses were rejected outright: (1) Males prefer left-brain communication channels; (2) Females prefer right-brain channels; (3) Individuals who are multi-dominant (strong preference for more than one type of thinking) are more satisfied with communication than single or double-dominant individuals. One explanation for the rejection of these hypotheses is that the female sample was significantly different than the general population of females. Partial support was registered for the other 8 hypotheses, indicating that brain dominance does influence communication channel preference and feedback. Unexpected results showed an uncanny consensus for certain communication channel preferences across all four quadrants of the brain, and consensus against certain communication channels-for all four organizations. These striking results indicated strong support for the effect of structuration in organizational communication. In essence, the power of structuration trumps the influence of brain dominance in organizations. Future studies will include a sample that is more left-brain/right-brain balanced (i.e. subjects will be chosen from a wide variety of professions, not just business) and the development of an independent survey instrument designed to more accurately measure the influence of brain dominance on communication preferences

    The invisible giant: a history of the Federated Miscellaneous Workers\u27 Union of Australia, 1915-1985

    This thesis provides an account of the history of the growth and character of the Federated Miscellaneous Workers\u27 Union of Australia from 1915 to 1985. With an emphasis on its New South Wales Branch and the years up until 1955, the argument is pursued in examinations of the union\u27s origins and its periods of major change and development. It is argued that the union was originally created by craft unionists out of the arbitration laws enacted in Australia during the first two decades of the century. The union\u27s general composition initially derived from the fact that its early manbers lacked the fundamental sectionalism assumed by craft unionism and these laws. The major changes to the union over its first 30 years occurred during the period of working class radicalism between 1917 and 1927 and in the aftermath of the Great Depression fran 1934 until the Second World War. As a consequence of this history, by 1945 the union reached a point of profound internal contradiction. It had a goverrment that had becone philosophically and structurally integrated with arbitration and a maonbership v*iere sections vAiich had come under militant rank-and-file leadership had developed to the extent that they were capable of taking their own direct action. Arising from this contradiction, between 1945 and 1955 the union underwent a major period of internal conflict and re-definition that ushered in a new and more radical leadership and generally accounts for the union\u27s subsequent growth and character. Between 1955 and 1970 the organisation developed into one of the largest, more progressive and most effective unions in Australia. Against the orthodoxy that has defined trade unions primarily as autonomous instruments of sectional economic interests, it is argued throughout that the union\u27s growth and character were determined by a much greater conplexity of social relations. While recognising the special significance of this institution\u27s relationship with the state and the labour movanent at large, central to the thesis is the proposition that at least as important to the union\u27s history as its immediate relationships were the wider social relations which these presupposed. Trade unions are evidence as well as agents of change in society and, it is argued, any understanding of their history depends on the extent to which both these aspects of their past and the relationship between them are able to be realised. The Giants who formed this world into its sensual existence and now seem to live in it in chains, are in truth the causes of its life and the sources of all activity, but the chains are the cunning of weak and tame minds which have power to resist energy according to the proverb the weak in courage is strong in cunning. Thus one portion of being is the Prolific, the other the Devouring: to the devourer it seams as if the producer was in his chains; but it is not so, he only takes portions of existence and fancies that the whole ... But the Prolific would cease to be Prolific unless the Devourer as a sea received the excess of his delights. Seme will say: \u27Is not God alone the Prolific?\u27 I answer: \u27God only Acts & Is in existing beings or Men\u27. These two classes of men are always upon earth, & they should be enemies: whoever tries to reconcile them seeks to destroy existence. William Blake, The Marriage of Heaven and Hell, 1789-9

    The Scan. Prototyping a post-human scenography

    Get PDF
    In our digital age, the human eye has lost its privileged positon as the sole and central audience of an unfolding perspectval world as it fnds itself challenged by a plethora of post-human eyes. Emerging technologies of vision such as 3D laser scanning—regarded as less faulty, faster and more accurate than the human eye— fnd an ever more central role in producton, analytcs, control and decision making. Architecture and scenography, practces that are both frmly shaped around the centrality of vision of the human subject, are challenged to fnd novel ways to address a hybrid audience of human and non-human modes of vision. How do we perform and build facing this new audience? How do we deceive or delight these new eyes? How do we infltrate and inhabit the parallel digital data space they create? How can we uncover their shadows, their glitches and fallacies and subvert the realism of their representaton? How can we design an architecture or scenography for the post-human eye

    Interpreting forest diversity-productivity relationships : volume values, disturbance histories and alternative inferences

    Get PDF
    Understanding the relationship between stand-level tree diversity and productivity has the potential to inform the science and management of forests. History shows that plant diversity-productivity relationships are challenging to interpret—and this remains true for the study of forests using non-experimental field data. Here we highlight pitfalls regarding the analyses and interpretation of such studies. We examine three themes: 1) the nature and measurement of ecological productivity and related values; 2) the role of stand history and disturbance in explaining forest characteristics; and 3) the interpretation of any relationship. We show that volume production and true productivity are distinct, and neither is a demonstrated proxy for economic values. Many stand characteristics, including diversity, volume growth and productivity, vary intrinsically with succession and stand history. We should be characterising these relationships rather than ignoring or eliminating them. Failure to do so may lead to misleading conclusions. To illustrate, we examine the study which prompted our concerns —Liang et al. (Science 354:aaf8957, 2016)— which developed a sophisticated global analysis to infer a worldwide positive effect of biodiversity (tree species richness) on “forest productivity” (stand level wood volume production). Existing data should be able to address many of our concerns. Critical evaluations will improve understanding.</p
