SUMMARY The term meditation can be used in many different ways, according to the technique to which it refers. Transcendental Meditation (MT) is one of these techniques. TM could serve as a model for research on spiritual meditation, unlike the meditation techniques based on secular knowledge. The purpose of the present study is to conduct a bibliographic review to organize scientific evidence on the effects of TM on neurophysiology, neurochemistry, and cognitive and behavioral aspects of its practitioners. To conduct this critical narrative review of the literature, we searched for scientific papers on the PubMed database of the National Center for Biotechnology Information. The keywords used in the search were Transcendental Meditation, Neuroscience of meditation e Meditation and behavior. We selected 21 papers that analyzed different aspects that could be altered through meditation practice. We concluded that TM has positive and significant documentable neurochemical, neurophysiological, and cognitive-behavioral effects. Among the main effects are the reduction of anxiety and stress (due to the reduction of cortisol and norepinephrine levels), increase of the feeling of pleasure and well-being (due to the increase of the synthesis and release of dopamine and serotonin), and influence on memory recall and possible consolidation. Further studies are needed using creative and innovative methodological designs that analyze different neural circuitry and verify the clinical impact on practitioners.

Since the early stages of the Hawke government, Australia???s taxation system has been modified with a view to attracting additional capital into the domestic venture capital market. In December 2002, the Howard government enacted the Taxation Laws Amendment (Venture Capital) Act 2002 (Cth) and the Venture Capital Act 2002 (Cth). This legislative package created a prospective concession primarily aimed at qualifying limited partnerships who participate in the Australian venture capital market. Subject to a rather stringent qualification criteria, such partnerships are treated as fiscally transparent for the purposes of Australian taxation law. In addition, the gains made upon the disposal of portfolio investments by these partnerships may not be subject to Australian capital gains tax ("CGT") or otherwise assessable as ordinary income. The central concept of these measures is the venture capital limited partnership ("VCLP"), and other fund of fund organisational forms which are founded on the limited partnership. For this reason, the provisions of the Taxation Laws Amendment (Venture Capital) Act 2002 (Cth) and the Venture Capital Act 2002 (Cth) are collectively identified as the "VCLP Concessions". This thesis has been prepared as a rigorous assessment of the VCLP Concessions. It draws upon an analysis of the nature and structure of venture capital investing to determine whether the particular features of the VCLP Concessions appropriately cater for the needs of prospective foreign investors. The efficacy and appropriateness of the VCLP Concessions from a policy perspective is also examined. Recommendations are provided which, if enacted, would address regions of structural inconsistency and improve the functioning of this concessional regime.

Issue Addressed: Access block (the prolonged wait for an inpatient hospital bed after emergency department (ED) treatment) is regarded as one of the major issues currently facing emergency medicine both in Australia and internationally. At this tertiary referral hospital review of existing data has indicated that access block has continued to increase in recent years, with a sharp rise in emergency access problems since July 1999 and is now identified as a system wide problem. Objective: This research thesis sought to explore four main areas of inquiry concerning access issues within this hospital. The first objective was to determine the current bed capacity of this hospital and identify the percentage of access block within this system. The second objective was to seek an understanding of hospital clinicians??? experiences of access block and to identify the factors they perceive directly influence patient access to acute in-patient care. The third objective was to identify change strategies to improve patient access. The final objective was to determine whether collaborative participation and involvement of clinicians would lead to a change in hospital culture and foster a collective ownership of access block as a hospital wide problem. Method: In a participatory action research inquiry, hospital clinicians within this hospital were invited to be co-researchers. The process of concurrent investigation and action followed a five- part sequence of entry, issue identification, planning, action and reflection. Both qualitative and quantitative research methods were used including in-depth semi structured interviews, focus groups, process mapping, control charts and statistical analysis. Results: The research findings revealed a consistently high level of access block experienced by this hospital with bed occupancy rates in excess of 90%. During the study, hospital clinicians??? became actively involved in identifying major access issues. Six main delay categories evolved: Access delays due to limited imaging and diagnostic services, patient transport delays, barriers within the patient discharges process, insufficient access and availability to transitional, hostel, rehabilitation and nursing home beds and delays due to poor internal processes within the wards. Multi-disciplinary working parties were formed to implement six intervention strategies identified by the hospital clinicians. These included: the development of a patient access database and hospital wide alert system for code red status, the design of a pharmacy discharge prescription tracking system, the establishment of a patient discharge lounge, a quality study of the aged care assessment team within the ED and the formation of a transport working group to evaluate an electronic transport booking system within the hospital. Conclusion: In recording the qualitative process involved in gaining hospital clinicians??? perceptions of the problem of access block some indicators of engagement and empowerment were documented. The success of this participatory action approach is based on the simple principal that those that are doing the job are in the best position to change or improve it.

This study extends research on the information content of qualified audit opinions in more developed markets to the emerging capital market in China. It investigates the market reaction to audit opinions of listed Chinese companies on the Shanghai Stock Exchange. A sample of 3128 company/year observations was included, with 386 modified audit opinions and 2742 unqualified audit opinions during the investigation period 1999 to 2003. The variable of interest is audit opinions. Control variables include those used in studies of developed countries, such as earnings surprise, concurrent bad news disclosure, audit report delay, leverage, the presence of loss and firm size. Also included are variables controlling for specific Chinese institutional characteristics, such as ???special treatment???, as well as bull and bear market indicators. When all modified audit opinions are combined, this study does not find evidence that the modified audit opinions have significant information value to Chinese investors. However, when modified audit opinions are classified by type, the market is found to significantly react to qualified audit opinions with explanatory notes and disclaimer audit opinions, which are the severest audit opinions investigated in this study. When the entire sample is partitioned by year, a significant stock price revision to modified audit opinions is documented in 2003. This study also examined in the Chinese context the Melumad and Ziv (1997) model of stock price response to avoidable and unavoidable modified audit opinions. Consistent with Melumad and Ziv (1997) predictions, the market reaction to avoidable audit reports is unclear, while investors view unavoidable audit reports as necessarily negative information. In conclusion, this study finds mixed evidence in support of the notion that the Chinese stock market views audit opinions as valuable information.

Introduction: In previous decades, the basis of child health and survival strategy in the developing countries has been the promotion of breastfeeding. However, transmission of HIV through breast milk to infants in the postnatal period has caused uncertainty over the best feeding technique. Previous policies in Uganda promoted breastfeeding even among HIV positive mothers without offering an informed choice of feeding mode. Consequently, the Ugandan Ministry of Health developed and adopted policy guidelines on feeding of infants and young children in the context of HIV/AIDS in 2001. However, little is known about their impact on infant feeding behaviour in Bushenyi district. Methods: This cross-sectional study conducted in Bushenyi district, Uganda, compared 94 HIV positive and 100 HIV negative mothers with infants aged less than 12 months on infant feeding practice, on the predictors of the different modes of infant feeding practice, and adherence to Ugandan infant feeding guidelines. Results: All HIV negative and 55% of HIV positive mothers were breastfeeding their infants aged less than 12 months. Among breastfeeding mothers, 85% of the HIV negative were breastfeeding non-exclusively. Of concern to the possibility of HIV transmission, 61% of the HIV positive mothers who were breastfeeding were doing so non-exclusively. Adherence to Ugandan infant feeding guidelines was higher in HIV positive mothers (67%) than in HIV negative mothers (41%). HIV negative mothers were more likely to be adherent if the mothers??? youngest infant was not a first-born (OR= 0.30, 95% CI = 0.10 ??? 0.88) and if they were aware of HIV transmission during pregnancy (OR = 2.60, 95% CI = 1.02 ??? 6.66). The single most predictive factor of adherence among HIV positive mothers was attendance at an infant feeding counselling session (OR= 5.63, 95% CI = 2.15???14.73). Conclusions: Counselling support is necessary for mothers to make infant feeding choices that are viable and sustainable. The self-reported method of assessing adherence in our study could have been sub-optimal and may therefore overestimate the adherent proportions reported here. Addressing development of better assessment methods and methods for improving adherence to guidelines is crucial for preventive strategies. Recommendations: Increase coverage of infant feeding counselling by introducing peer counsellors in the community.

The main aims of the investigation conducted here are to draw out important debates in theory and in the South African social context over the concepts of responsibility and accountability for human rights abuse, and to look at how these were present within, and impacted on, discussions within and around the Truth and Reconciliation Commission. The TRC did not specifically discuss or define theoretical concepts of responsibility or accountability. However, I argue that it is possible to draw out some important features of its implicit approach ??? particularly in terms of its emphasis on collective responsibility and social context (in addition to individual responsibility), and its emphasis on moral arguments for individuals and collectives to accept responsibility and hold themselves accountable by contributing to future change. This ambitious and complex approach raised some important theoretical issues, which have been discussed and debated in the theoretical literature. These include: the relationship between individual responsibility, collective responsibility and the influence of ???the system???; the nature of collective responsibility; the nature of morality; the distinction between moral and political responsibility; and how individuals and collectives can or should be held accountable. In South Africa, these theoretical debates inter-mingled with a range of other factors, including individual and collective interests, motives and political perspectives. From an analysis of the existing literature on the TRC and original interviews conducted with key informants, I draw out three main opposing views which I argue arose in the South African social context about responsibility and accountability, and what the TRC could and should have done to address these. In a detailed analysis of the TRC???s hearings and Final Report, I draw out how theoretical debates, and these three opposing views, were present within and impacted on the TRC???s work. I argue that it was impossible for the TRC to satisfy everyone and resolve these debates, and that its approach led to unrealistic expectations of its work and its role more generally. This has impacted negatively on how the TRC was and is perceived.

This thesis considers the colonial literary relationship between the ???centre??? and the ???margin??? in the field of post-colonial counter-discourse. As such, this thesis investigates the possibility of disrupting the dominance of Empire, which is often rhetorically constructed through the certainty of the parent and child binary relationship. By analysing the orphan???s affiliational associations, which exist beyond the traditional binary of parent and child in the colonial relationship, I argue that the orphan, as both figure and trope, becomes a site of resistance to the dominant colonial discourse. Re-reading Charles Dickens???s Great Expectations with two Australian re-writings of his text in mind ??? Peter Carey???s Jack Maggs and Gail Jones???s Sixty Lights ??? this thesis investigates the particular case of post-colonial counter-discursive practice, and explores the way in which the orphan figure in each re-writing inscribes their expectations and thereby refigures the power hierarchy between the canonical European text and the post-colonial re-writing. In order to do so, I have organised this thesis into four main chapters, each of which develops a specific interrogation of the orphan figure in light of post-colonial theory and criticism. So, chapter one considers the colonial figure and the trope of parent and child, investigating the influence that this trope wields in casting the racialised colonial Other as ???savage??? and ???primitive???, but, ultimately, ???child-like???. Chapter two furthers this observation by highlighting the disruptive affect of such naturalised perspectives of the colonial Other???evidenced in post-colonial theory through the motion of the key concepts of ambivalence and abjection. And, it is in this context that chapters three and four stand as direct examinations of the disruptive affect of the orphan figure. Discussing Peter Carey???s Jack Maggs and Gail Jones???s Sixty Lights (respectively), these last two chapters formalise the subversive agency assumed by the orphan, and locate it in the very practice of ???writing back to the centre???.

???Journey??? as a term in the dictionary, indicates a distance covered in travelling, usually by land, from one place to another. In my paper, ???journey??? becomes equal to life experience, consisting of time, space or place, and thoughts. I see my life as a linear journey, made up of many points, in different time and space, facing diverse scenes, causing various emotions, and creating distinct relationships with the world. My project deals with time, space and thoughts in my life???s journey. I have turned to the space of everyday life in order to explore its shifting physical, social and psychological dimensions. This is where I would locate my work in relation to Contemporary Art, where the relationship between the inner and outer world, between private and public, between art and everyday, are also the key issues. These are my truly personal experience of my stay in Australia, where I have been provided an opportunity to experience the differences in various ways. Since all experiences take place in time and space, the two categories provide a comprehensive framework, in which my thoughts have a place to occur and develop. In my real life experience, what I have been through is not only to confront the conflicts and the uneasiness, but also to understand the differences, and then to accept and get used to these until I have harmony in my heart.

The HIV epidemic has caused a health crisis globally. Using mathematical and statistical tools, we have analysed and modelled data from animal models of HIV, HSV and influenza virus, in order to understand the role of neutralising antibodies (nAbs), CD4+ T cells, CTLs and APCs in HIV infection and the implications of this for HIV vaccine design. Our analysis suggests that antibody and CTL responses confer protection at different stages of HIV infection. Passive antibodies confer protection against SHIV89.6PD infection by either neutralising the initial viral inoculum or reducing the acute viral level and growth. Consequently, CD4+ T cell preservation allows the immune system to control long-term disease progression. Therefore, vaccines that elicit high nAb levels during early infection may induce sterilising immunity or delay disease progression. By contrast, we observed that vaccine-elicited CTLs did not proliferate until day 10 following SHIV89.6P infection. More potent CTL-inducing vaccines did not reduce this delay, but further increased it and reduced CTL growth. However, more potent vaccines result in better memory CTL formation, better CD4 preservation and improved disease outcome. HIV vaccine design should aim to reduce the delay in CTL activation. To further understand the pathogenesis of HIV, we investigated the relationship between viral load and CD4+ T cell levels using simple ODE models. Our results demonstrate a positive correlation between peak viral level and the acute CD4+ T cell depletion in SHIV89.6P infection, which demonstrates how reduction of peak viral level significantly preserves CD4+ T cells. Surprisingly, this relationship between virus and CD4+ T cells was reversed in SIVmac239 infection and other CCR5 tropic infections. Future work should focus on understanding this difference between X4 and R5 infections. Regardless of viral infections, antigen presentation is essential for stimulating effective immune responses. Our study on influenza and HSV-1 infections suggests that antigen loading rate of APCs determines the magnitude of antigen presentation and the APC decay is mainly due to the degradation of pMHC, not CTL killing. The slow kinetics of HIV viral growth may be one factor that limits the level of antigen presentation and subsequent CTL response.

This thesis concentrates on identifying and examining ambivalence and contradictions in the discourse of moral education within mid-nineteenth-century British literature. Through an analysis of contemporary women???s advice literature and the fiction of two authors I locate the discourse within the larger ideologies of femininity (which defined women as different from men based on their gender) and domesticity (which assigned women to the domestic sphere because of gender) and analyse its fundamental features. The mother was a representation of the ideal woman and thus the measure for standards of behaviour within the discourse of moral education, and, indeed, within the ideologies of femininity and domesticity for all women. I focus on the inconsistencies that the discourse of moral education attempts to mask in its representations of women. Part I (Chapters One, Two and Three) examines the social standards of behaviour for mothers established in women???s advice literature and the literature???s simultaneous resistance to these standards. Chapters Four and Five are dedicated to Anne Bront?????s two novels, Agnes Grey and The Tenant of Wildfell Hall; in particular, Chapter Five examines how Helen Huntingdon???s attempts to be the perfect moral mother are constantly open to conflicting ideological interpretation exposing ambivalence within the discourse of moral education and in the novel???s approach to the discourse. Chapters Six, Seven and Eight focus on many of Gaskell???s short stories as well as her novel Ruth. The inherent conflict within the discourse of moral education results in three separate images of motherhood for Gaskell???s fiction: traditional mothers who gain their moral influence through an association with death, the ideologically contradictory moral mother, and women who use maternal traits to live in communities of women without men. I conclude that none of the texts are categorically resistant to or complicit with the ideals within the discourse of moral education but are internally contradictory. In particular, the fiction simultaneously promotes conventional ideals of womanhood and moral mothers as self-sacrificing and nurturing and offers a vision of women either in unhappy compliance with or otherwise defying these ideals, for example, by living in unconventional relationships without men.

With the rapid growth in the development of economic reform in the People???s Republic of China since the late 1970s, China???s legal system has also been undergoing major reform and development. This has seen the emergence of a major effort to draw upon the law reform experiences of other countries, especially in the area of economic law reform. As the securities industry is a key component of an increasingly corporatised market economy, it has been necessary to adopt an effective body of securities laws. Disclosure is the fundamental issue of securities laws as it exists in market transactions and the conduct of market participants. As such, the development of an appropriate body of disclosure law and practice is vital to the integrity of securities law and ultimately to the market economy. It is for this reason that this dissertation looks at the development of China???s securities market and corporate disclosure laws, and identifies the forces that have led to its current form and content. This dissertation argues that China???s legal system must be seen as a product of China???s distinctive history and local circumstances. It analyses the current nature of China???s corporate disclosure laws and notes that China???s law reformers have relied heavily upon the US model which may not necessarily suit China. Based upon a number of theoretical understandings of the transplantation and development of law, this dissertation argues that China???s approach to law reform in this area has not always produced a body of law that is appropriate to China???s particular circumstances. It suggests that valuable insights can be gained from a comparison of the methods of corporate disclosure law reform that were followed in Australia. The Australian experience is relevant to China as Australian lawyers and regulators have played an important role in fashioning securities regulation in Hong Kong and as Hong Kong has sometimes been seen as providing useful models for China itself.
