Red clover (Trifolium pratense) isoflavones and serum homocysteine in premenopausal women : a pilot study

Background: There is limited information on the effect of isoflavones on homocysteine concentrations, a risk factor for a number of chronic diseases. Methods: Twenty-three premenopausal women participated in a double-blind, randomized, parallel study for four menstrual cycles. Subjects consumed either placebo or purified red clover (Trifolium pratense) isoflavone (86mg/day) tablets. Blood samples were collected weekly during cycles 1, 3, and 4 for determination of serum folate and total homocysteine concentrations. Dietary intake was monitored monthly. Results: Concentrations of folate and homocysteine in serum did not change significantly in either group, and there were no significant differences observed between the follicular and luteal phases of the menstrual cycle. The participants' dietary records indicated that nutrient intake was constant, and compliance was confirmed by analysis of urinary isoflavone concentrations and tablet counts in returned containers. Conclusions: These results suggest that in the absence of any dietary modification, supplementation with purified isoflavones that are predominantly methoxylated has no effect on serum homocysteine or folate in premenopausal women.

Developing a theatre of the integrated actor : the application of the Suzuki actor training method within three theatrical contexts

This research project examines the application of the Suzuki Actor Training Method (the Suzuki Method) within the work ofTadashi Suzuki's company in Japan, the Shizuoka Performing Arts Complex (SPAC), within the work of Brisbane theatre company Frank:Austral Asian Performance Ensemble (Frank:AAPE), and as related to the development of the theatre performance Surfacing. These three theatrical contexts have been studied from the viewpoint of a "participant- observer". The researcher has trained in the Suzuki Method with Frank:AAPE and SP AC, performed with Frank:AAPE, and was the solo performer and collaborative developer in the performance Surfacing (directed by Leah Mercer). Observations of these three groups are based on a phenomenological definition of the "integrated actor", an actor who is able to achieve a totality or unity between the body and the mind, and between the body and the voice, through a powerful sense of intention. The term "integrated actor" has been informed by the philosophy of Merleau-Ponty and his concept of the "lived body". Three main hypotheses are presented in this study: that the Suzuki Method focuses on actors learning through their body; that the Suzuki Method presents an holistic approach to the body and the voice; and that the Suzuki Method develops actors with a strong sense of intention. These three aspects of the Suzuki Method are explored in relation to the stylistic features of the work of SPAC, Frank:AAPE and the performance Surfacing.

Languaging the actor : an examination of the terminology used in actor training

Throughout the twentieth century increased interest in the training of actors resulted in the emergence of a plethora of acting theories and innovative theatrical movements in Europe, the UK and the USA. The individuals or groups involved with the formulation of these theories and movements developed specific terminologies, or languages of acting, in an attempt to clearly articulate the nature and the practice of acting according to their particular pedagogy or theatrical aesthetic. Now at the dawning of the twenty-first century, Australia boasts quite a number of schools and university courses professing to train actors. This research aims to discover the language used in actor training on the east coast of Australia today. Using interviews with staff of the National Institute of Dramatic Art, the Victorian College of the Arts, and the Queensland University of Technology as the primary source of data, a constructivist grounded theory has emerged to assess the influence of last century‟s theatrical theorists and practitioners on Australian training and to ascertain the possibility of a distinctly Australian language of acting.

Undressing the actor : the erotic relationship with the audience

The intimacy and eroticism of the actor’s relationship with the audience is captured in the ecstatic revelation of the actor “being in the moment.” Drawing on the theories of Freud and Sartre and twenty years of performance praxis, this paper explores the exchange of erotic discourse between stage and spectator that not only heightens the experience of the liveness of theatre, but creates a symbiosis that is silently negotiated, agreed upon and sensuously performed during the suspended timeframe of the theatrical event. The actor draws the audience into the erotic transaction through various dramatic devices: the seduction of the soliloquy, the somatic and verbal discourses, the sensuality of light and costuming. The audience responds with its own paralingual and verbal foreplay: the playfulness of laughter, the slapping of hands and, most significantly, the gaze. While the gaze is often perceived as a form of voyeurism, this paper argues that the gaze of consensual agreement between audience and actor can work to unmask inhibitions enabling the actor to create the truth of the moment in complete abandon.

The impact of red light cameras on safety in Arizona

Red light cameras (RLCs) have been used in a number of US cities to yield a demonstrable reduction in red light violations; however, evaluating their impact on safety (crashes) has been relatively more difficult. Accurately estimating the safety impacts of RLCs is challenging for several reasons. First, many safety related factors are uncontrolled and/or confounded during the periods of observation. Second, “spillover” effects caused by drivers reacting to non-RLC equipped intersections and approaches can make the selection of comparison sites difficult. Third, sites selected for RLC installation may not be selected randomly, and as a result may suffer from the regression to the mean bias. Finally, crash severity and resulting costs need to be considered in order to fully understand the safety impacts of RLCs. Recognizing these challenges, a study was conducted to estimate the safety impacts of RLCs on traffic crashes at signalized intersections in the cities of Phoenix and Scottsdale, Arizona. Twenty-four RLC equipped intersections in both cities are examined in detail and conclusions are drawn. Four different evaluation methodologies were employed to cope with the technical challenges described in this paper and to assess the sensitivity of results based on analytical assumptions. The evaluation results indicated that both Phoenix and Scottsdale are operating cost-effective installations of RLCs: however, the variability in RLC effectiveness within jurisdictions is larger in Phoenix. Consistent with findings in other regions, angle and left-turn crashes are reduced in general, while rear-end crashes tend to increase as a result of RLCs.
