Sexual and emotional variables influencing sexual response to erotica: a psychophysiological investigation

The relative contribution of attentional and emotional factors to the physiological and subjective sexual arousal elicited by erotic film was evaluated. Sexual arousal, attentional, and emotional responses were measured while 30 men were presented with a series of erotic film segments. Levels of physiological and subjective sexual arousal were higher when subjects became absorbed in the activities portrayed in the film and when they experienced the depicted erotic encounters as appetitive, than when they were distracted and perceived the encounters as aversive. The erotic film elicited a diminished startle response to a sudden burst of white noise presented during stimulation relative to the nature film, suggesting that at a physiological level the erotic segments of film were processed as more appetitive in valence. The level of sexual arousal elicited by the erotic segments was related to the extent to which subjects were entertained by the film, even though there was considerable anxiety generated by the portrayed sexual scenarios. Sexual response was not significantly correlated with trait measures of absorption (as indexed by the Tellegen Absorption Scale) nor with vividness of imagery (as assessed by the Betts Questionnaire upon Mental Imagery). Arousal was related to state-assessed attentional and emotional variables, and physiological measures of emotional response, demonstrating the multidimensional nature of the sexual response Future directions for comparing male sexual response patterns with female response patterns are suggested.

Reflexive modernity and the art of public communication

In 2000, Victoria’s largest regional council, the City of Greater Geelong, allocated $200,000 to fund a community art and place-making project in inner Geelong West. The Walk West project was conceptualised and lobbied by a community group for six years. The project addressed the impact of a large section of freeway installed in the seventies and its consequences for quality of life in the locality.

This article reports on an example of highly developed community relations. It examines public art and placemaking as public communication tools and their relationship to political and social activity in post-amalgamation Victoria. In particular it applies the theories of Ulrich Beck and the notion of reflexive modernity in risk society where citizens’ initiative groups will play an increasingly important role in reclaiming the biological and cultural heritage lost as a result of ‘progress’.

Accuracy of body size estimation: Role of biopsychosocial variables

This study evaluated factors related to the perceptual disturbances of body image. Using a digital body image computer program, 191 participants (107 women, 82 men) adjusted an image of their body to the perceived actual size at five body regions; chest, waist, hips, thighs and calves. A neutral object (a vase) was also adjusted to partial out the level of perceptual distortion present with a neutral object. Men and women overestimated the size of the neutral object and their body image. Among women, overestimation was primarily predicted by high levels of depression, and media and peer influences to be thinner and increase muscles. Among men, overestimation was predicted by high BMI, media influences to lose weight and increase muscles, and peer influences to increase muscles. These findings suggest that perceptual accuracy of body image is primarily predicted by biopsychosocial influences.

Discovering associations with numeric variables

This paper further develops Aumann and Lindell's [3] proposal for a variant of association rules for which the consequent is a numeric variable. It is argued that these rules can discover useful interactions with numeric data that cannot be discovered directly using traditional association rules with discretization. Alternative measures for identifying interesting rules are proposed. Efficient algorithms are presented that enable these rules to be discovered for dense data sets for which application of Auman and Lindell's algorithm is infeasible.

The relevance of demographic variables in assessing student satisfaction: a study of international postgraduate students

Servicing an increasingly diverse international student community in the globally competitive education market is a challenge faced by Australian universities. Market forecasts indicate a seven-fold increase in the number of students seeking higher education overseas by 2025 (Bohm et al, 2002) and with the growing diversity and competitiveness of the industry, universities will need to focus on factors influencing student satisfaction to improve service quality where required.

This paper, using logistic regression, ANOVA, and MANOVA, investigates the influence of country, age and gender with regard to satisfaction among international postgraduate students from four Asian countries studying in universities in Victoria. The results indicate that there is an inverse relationship between age and satisfaction among postgraduate students while the gender of the students does not have an impact on satisfaction, and that significant differences are evident between the four countries investigated with respect to the levels of satisfaction.

The discovery of generalized causal models with mixed variables using MML criterion

One major difficulty frustrating the application of linear causal models is that they are not easily adapted to cope with discrete data. This is unfortunate since most real problems involve both continuous and discrete variables. In this paper, we consider a class of graphical models which allow both continuous and discrete variables, and propose the parameter estimation method and a structure discovery algorithm based on Minimum Message Length and parameter estimation. Experimental results are given to demonstrate the potential for the application of this method.

Bourdieu`s reflexive sociology and `spaces of points of view`: whose reflexivity, which perspective?

This paper considers Bourdieu's concepts of perspectivism and reflexivity, looking particularly at how he develops arguments about these in his recent work, The Weight of the World (1999) and Pascalian Meditations (2000b). We explicate Bourdieu's distinctive purposes and deployment of these terms and approaches, and discuss how this compares with related methodological and theoretical approaches currently found in social and feminist theory. We begin by considering three main ways in which 'reflexivity' is deployed in current sociological writing, distinguishing between reflexive sociology and a sociology of reflexivity. This is followed by a discussion of the main aspects of Bourdieu's approach to 'reflexive sociology' and its relation to his concepts of social field, perspectivism and spaces of point of view. He argues that we need to interrogate the idea of a single 'perspective' and account especially for the particularity and influence of the 'scholastic' point of view. He characterizes this latter point of view as unaware of its own historicity and as largely concerned with contemplation and with treating ideas primarily as abstractions (Bourdieu, 2000b). Bourdieu's intervention is to argue, as he has throughout his work, for a more reflexive account of one's location and habitus, and for sustained engagement with ideas and social issues as practical problems. Bourdieu exhorts researchers to work with 'multiple perspectives' (Bourdieu et al., 1999, p. 3), the various competing 'spaces of points of view', without collapsing into subjectivism or relativism. We then consider recent feminist engagements with and critiques of Bourdieu's notion of reflexivity and chart some of the main points of contention regarding its relevance and conceptual potential for theorizing gender identities and transformations in current times. We conclude with a brief outline of how we are working with a reflexive sociological approach in a cross-generational study of young women in difficult circumstances, 'on the margins' of education and work.

Granger causality among house price and macroeconomic variables in Victoria

This study analyses the dynamic causality of four macroeconomic variables on house prices. The four macroeconomic variables have interrelationships with house prices in certain lagged terms, but these relationships are not always the same as the notions put forward in prior research. The relationships are detected to be unstable in the three observation periods. The instability of these relationships would cause difficulty in predicting house prices in the market, especially for policy makers and market participants.

Community reintegration of ex-prisoners : type and degree of change in variables influencing successful reintegration

Community reintegration of ex-prisoners is an important issue in efforts to reduce recidivism. The present study examined the multiple, complex, and dynamic nature of variables influencing successful reintegration by assessing the type and degree of change in reintegration variables over time. Participants were 79 adult prisoners (54 male, 25 female) who completed a prerelease questionnaire 1 month before their release, which focused on prison-related variables, participant background, and anticipated conditions upon release. A postrelease questionnaire was administered to the same participants at 1-4 weeks and 3-4 months postrelease, focusing on the quality of life conditions experienced following release. Results indicate that current health ratings and several indicators of drug use were significantly different over the three measurement phases. Ratings of employment and housing stability, finance, and social support were unchanged over the postrelease period. Theoretical implications of the present investigation for reintegration theory are discussed, together with practical applications.

Effect of process variables on formation of dynamic strain induced ultrafine ferrite during hot torsion testing

Ultrafine grain sizes were produced using hot torsion testing of a 0.11C-1.68Mn-0.20Si (wt-%) steel, with ultrafine ferrite (<1 µm) nucleating intragranularly during testing by dynamic strain induced transformation. A systematic study was made of the effect of isothermal deformation temperature, strain level, strain rate, and accelerated cooling during deformation on the formation of ultrafine ferrite by this process. Decreasing the isothermal testing temperature below the Ae₃ temperature led to a greater driving force for ferrite nucleation and thus more extensive nucleation during testing; the formation of Widmanstätten ferrite prior to, or early during, deformation imposed a lower temperature limit. Increasing the strain above that where ferrite first began 0.8 at 675C and a strain rate of 3 s¯¹ increased the intragranular nucleation of ferrite. Strain rate appeared to have little effect on the amount of ferrite formed. However, slower strain rates led to extensive polygonisation of the ferrite formed because more time was available for ferrite recovery. Accelerated cooling during deformation followed by air cooling to room temperature led to a uniform microstructure consisting of very fine ferrite grains and fine spherical carbides located in the grain boundaries regions. Air cooling after isothermal testing led to carbide bands and a larger ferrite grain size.
