This essay examines how the found footage films of Martin Arnold (Alone: Life Wastes Andy Hardy, 1998) and Peter Tscherkassky (Outer Space, 1999 and Dream Work, 2002) can be read as a belated response to Peter Wollen’s 1970s splitting of the avant-garde. Wollen’s tactical move, his article The Two Avant-gardes (Wollen, 1975 and revised in 1982) marked a historic moment when both critics and artists gained easy access to the film editing-machine for both film analysis and reflexive film production respectively. Wollen’s text asserted differences between a political and formalist avant-garde, opening up a space between structuralist/materialist film and feminist film theory and its counter-cinema. This move enabled Laura Mulvey and other Cine-Feminists to eschew formalism in favor of a political feminist counter–cinema and further, as part of its move into the academy, to develop and enlist Textual Analysis as a tool for uncovering the patriarchal ideologies at the heart of Hollywood melodrama.

The quality of life of people with end stage kidney disease (ESKD) has traditionally been measured using instruments that emphasise objective health status. The present study validates an alternative measure, the Personal Wellbeing Index (PWI), which measures subjective wellbeing. An Australian ESKD sample (N = 172, Mean age = 64.04, SD = 14.82) completed the PWI as well as health-specific quality of life measures. The PWI was subject to confirmatory factor analysis, and a series of regressions and between-group comparisons were performed to reveal that it is a psychometrically appropriate measure for this sample. The PWI and health-specific measures each yield different and complementary results. Thus, the PWI is proposed as a complement to existing health-related quality of life tools, in order to broaden understanding of the patient’s subjective experience. The resulting profile is argued to better inform targeted interventions to improve the quality of life of people with ESKD.

Though subjective wellbeing (SWB) is generally stable and consistent over time, it can fall below its set-point in response to adverse life events. However, deviations from set-point levels are usually only temporary, as homeostatic processes operate to return SWB to its normal state. Given that income and close interpersonal relationships have been proposed as powerful external resources that are coincident with higher SWB, access to these resources may be an important predictor of whether or not a person is likely to recover their SWB following a departure from their set-point. Under the guiding framework of SWB Homeostasis Theory, this study considers whether access to a higher income and a committed partner can predict whether people who score lower than normal for SWB at baseline will return to normal set-point levels of SWB (rebound) or remain below the normal range (resigned) at follow-up. Participants were 733 people (53.3 % female) from the Australian Unity Longitudinal Wellbeing Study who ranged in age from 20 to 92 years (M = 59.65 years; SD = 13.15). Logistic regression analyses revealed that participants’ demographic characteristics were poor predictors of whether they rebounded or resigned. Consistent with homeostasis theory, the extent of departure from the proposed normal SWB set-point at baseline was significantly associated with rebound or resignation at time 2. These findings have implications for the way that SWB measures can be used in professional practice to identify people who are particularly vulnerable to depression and to guide the provision of appropriate and effective therapeutic interventions.

In the context of emergency services and first responders (i.e. military), the ability to select personnel who have the innate ability to work well in highly charged environments would be advantageous. While there have been some efforts to explore the relationship between personality traits and physiological reactivity in the context of the emergency services, differences in stress responses between civilians and military personnel have not yet been investigated. Therefore the aim of the current study was to examine the relationship between personality, resilience and physiological stress responses. Fifteen civilians and 16 military personnel completed online personality (IPIP) and resilience (CD-RISC) inventories prior to commencing the experimental component of the study. The Mannheim Multi-component Stress Test (MMST) which utilises cognitive, audio, visual and motivational components was employed to elicit an acute stress response. Measures of correct responses and reaction time were sampled during the MMST. Prior to and following exposure to the MMST, positive and negative affect were measured (PANAS), and heart rate was sampled continuously across the study period. Results indicated that Military participants rated significantly lower than civilians on neuroticism; however there were no differences between groups for resilience or any of the other personality traits. Military participants displayed less emotional reactivity and less negative affect following the MMST testing period, and appeared to perform better on the MMST when compared to the civilian sample. However, there was no significant difference in heart rate measures between groups. Collectively, these results provide support for the broaden and buildhypothesis and the transactional stress theory. The results also build on previous empirical stress literature and support the effectiveness of the MMST in laboratory induced stress. Suggestions for future research in the area of resiliency and stress will be discussed. From an applied context, further research in this area may assist in military recruitment processes to place individuals in roles to which they are most suited within the Defence Force.
