Australia, Asia and cultural anxiety : inaugural AHA Anniversary Public Lecture, given at the Grand Hotel, Mildura on 29 September (2003).

My theme tonight is the recurrent idea that Australia could be expected to have an Asian future. From the 1880s there developed a speculative literature around the notion that Asia ('generic Asia' as I prefer to call it) would exert an increasing influence, possibly a determining influence, on the development and settlement of the Australian continent. There is a certain pathos about this story of a young, newly formed community on the threshold of nationhood finding Asia blocking its path. Would the ensuing contest be the making of white Australia; would the young nation define its national purpose and assert its right to exist or would it succumb to a force more powerful? Would white Australia become nothing more than a faint historical memory, a failed experiment in the complex and uncertain business of nation building? In short, would white Australia fail?

Peer groups, power and pedagogy : the limits of an educational paradigm of separation

In contrast to the plethora of literature that suggests that the increasing gulf between teachers and young people is due to the shifting interests and expectations of young people, the focus of this paper is on the roles teachers play in this relationship. Provoking interest is a concern that some of the assumptions that underpin 'mainstream' pedagogic theory and practice might actually contribute, albeit unwittingly, to hardening rather than softening the communication divide. Drawing on an incident that took place between a group of 7–8 year old males in a primary school setting, the authors reveal the limits of a teaching paradigm that encourages teachers to adopt authoritative positions from which to separate and individualise student behaviour. In theoretical terms, they argue that the application of this paradigm asserts an exaggerated notion of agency to individuals in the construction of identity. In practical terms it promotes processes that individualise behaviour as a way of dealing with miscreance. Together these manifest themselves as a 'pedagogy of separation'. The process of building more productive pedagogic relationships, it is concluded, needs to begin with teachers better recognising and engaging with the collective investments of young people.

A new second-order method for blind signal separation from dynamic mixtures

This paper presents a new approach to separate colored stationary signals mixed by convolutive channels. A cost function is proposed by employing linear constraint to the demixing vectors. The linear constraint is shown to be sufficient for avoiding trivial solution. The minimization of the cost function is performed using the Lagrangian method. Simulation results demonstrate the performance of the algorithm.

Blind source separation based on phase and frequency redundancy of cyclostationary signals

This paper presents a new method for blind source separation by exploiting phase and frequency redundancy of cyclostationary signals in a complementary way. It requires a weaker separation condition than those methods which only exploit the phase diversity or the frequency diversity of the source signals. The separation criterion is to diagonalize a polynomial matrix whose coefficient matrices consist of the correlation and cyclic correlation matrices, at time delay .TAU. = 0, of multiple measurements. An algorithm is proposed to perform the blind source separation. Computer simulation results illustrate the performance of the new algorithm in comparison with the existing ones.

The role of performance anxiety in the development and maintenance of sexual dysfunction in men and women

The current study evaluated the association between attitudes toward sex, stress, relationship quality, performance anxiety, and sexual dysfunction among 157 men (114 dysfunctional, 43 functional) and 186 women (84 dysfunctional, 102 functional). The results demonstrate that the main factors related to all types of sexual dysfunction among men were attitudes toward sex, conflict in their relationship, and performance anxiety. For women, the main factors related to all types of sexual dysfunction were attitudes toward sex, relationship quality, and performance anxiety. These results demonstrate the central role of performance anxiety in either the development or maintenance of sexual dysfunction among both men and women. Clearly, this is an area that has to be considered in any treatment program for sexual dysfunction. (PsycINFO Database Record (c) 2008 APA, all rights reserve

The separation of ownership and control under a happiness-based theory of the corporation

Explores the happiness-based theory of the corporation, suggesting that there is no conflict between the pursuance of economic and social objectives on the basis that their interplay is required to facilitate shareholder happiness. Considers: (1) the Berle-Means hypothesis and the separation of ownership and control, the dominant governance structure for large companies; (2) a happiness-based perspective on the separation; and (3) law reform applicable to a happiness-based theory. Argues that the separation of ownership and control is not in shareholders' best interests because the structure is not conducive to the happiness of individual shareholders and should be reformed.

The psychological impact of extended temporary protection

Against the background of the recent international trend of a greater reliance on deterrence measures in managing the flow of asylum seekers, this paper discusses the implementation of the temporary protection visa (TPV) in Australia. It focuses on the psychological impact of the TPV policy on individual asylum seekers and how this unlimited temporary status affects the overall process of settlement. This study is based on personal narratives constructed by individual asylum seekers during one-on-one interviews aimed at sketching the mental and psychological manifestations of stressful events in their lives as TPV holders. What is particularly revealing among many of these TPV holders is the fact that their pre-migration traumatic experiences are compounded by a post-migration condition of being in indefinite "temporary" protection. This is further exacerbated by a prevalence of racialized discourses and exclusionary policies advocated by the host government. Past trauma and persecution, combined with present family separation and social exclusion, and further compounded by uncertainty about the future, had resulted in almost chronic states of anxiety and depression among a significant number of TPV holders.

Women`s satisfaction with life following marital separation : coping resources and adjustment of lone-parent women

This questionnaire study examined the adjustment of 245 lone-parenting women following marital separation. A composite model included intrapsychic variables as intervening between demographic and contextual variables and adjustment (life satisfaction). Regression analyses showed that the demographic and contextual variables were partially mediated by the intrapsychic variables. The path model indicated that the intrapsychic variables (sense of coherence, control, depression, and grief) had a direct impact on life satisfaction and that there was an indirect path for depression through sense of coherence (SOC) and control. It was concluded that the intrapsychic variables had a more powerful relationship with women's post-separation life satisfaction than did the demographic/contextual variables. Social implications and recommendations for future policy are considered.

Assessing adult adjustment to relationship separation : the Psychological Adjustment to Separation Test (PAST)

Relationship separation is associated with substantial adult adjustment problems. The Psychological Adjustment to Separation Test (PAST) was developed as a self-report measure of 3 key dimensions of separation adjustment problems: lonely negativity, ex-partner attachment and coparenting conflict. Two independent samples (n = 219 and n = 169, respectively) of recently separated adults, 60% of whom had children, completed the PAST and other measures of general adjustment. Exploratory and confirmatory factor analyses demonstrated a replicable 3-factor structure, with each factor showing satisfactory test–retest and internal reliability and good convergent and discriminant validity. The PAST meets initial criteria for a potentially useful new measure of adult separation adjustment.

Separation of conjoined twins: experiences of perioperative nurses and their recommendations

Background: Within an 8-month period, an unprecedented and historical first in Queensland, Australia, the perioperative nurses were members of teams involved in the surgical separation of two sets of conjoined twins. Little is known about the (dis)stress that some of these perioperative nurses experienced nor how best to support them during such experiences.

Aim: The aim of this paper is to report on the qualitiative study that explored the experiences of those perioperative nurses involved in the surgical separation of cojoined twins and from their stories propose recommendations to support perioperative nurses who are confronted with such workplace experiences.

Methods: Using a narrative methodology, nine perioperative nurses shared their stories of being involved in the surgical separation of conjoined twins in Australia. Narrative and thematic analyses were conducted and recommendations to support perioperative nurses through workplace (dis)stress were identified. Participants validated the findings and recommendations.

Findings: The analyses revealed the themes of professionalism, teamwork, 'them vs. us' and emotional loads.

Discussion: The sensationalism around the rarity of conjoined twins brought an intensive intrusiveness from the world media. As a result, secrecy within the hospital about the conjoined twin cases created divisions between those perioperative nurses on the teams and those not. The processes and outcomes of the two surgical cases were in contrast to each other. For some perioperative nurses this caused distress. It is essential that professional support is offered in a way in which the perioperative nurse can take it up without fear of negative judgement.

The impact of social phobia on quality of life: the advantages of anxiety support groups

Social phobia is the least well known of the anxiety disorders and it is perhaps also the least well understood. The lifetime prevalence rates for social phobia, which range from 3% to 13%, clearly indicate that social phobia is a widespread mental health problem. Those affected by social phobia often live their lives around the limitations of the disorder including avoidance of social situations, depression and loneliness. Thus for these individuals, social phobia becomes an impairing disorder which can have long-term negative impacts on work performance and social relationships. Anxiety support groups offer an important resource to sufferers of social phobia. Support groups provide a potentially safe and confidential environment in which to interact with others. Support groups also have the potential to help to de-stigmatize the disorders for sufferers as all members share similar concerns that are often not well understood by others. The practical benefits to be derived from anxiety support groups are presented through the discussion of two case studies.
