 In the context of reproduction, glucocorticoids (GCs) are generally considered to have negative effects. However, in well-studied model species, GCs fluctuate predictability across the estrous cycles, and short-term increases promote healthy ovarian function. Reproductive challenges have plagued captive elephant populations, which are not currently self-sustaining. Efforts to understand reproductive dysfunction in elephants have focused on the suppressive effects of cortisol, but the potential permissive or stimulatory effects of cortisol are unknown. In this study, we provide a detailed examination of cortisol patterns across the estrous cycle in Asian elephants (Elephas maximus). Time series analysis was used to analyze cortisol and progesterone data for a total of 73 cycles from eight females. We also compared cortisol profiles between females that successfully conceived and females that failed to conceive despite repeated mating attempts. Our results revealed that cortisol fluctuates predictably across the estrous cycle, with a peak during the second half of the follicular phase followed by low levels throughout the luteal phase. Furthermore, this pattern was significantly altered in nulliparous females; cortisol concentrations did not decline during the luteal phase to the same extent as in parous females. This study highlights the complexity of cortisol signaling and suggests future directions for understanding the role of cortisol in reproductive dysfunction.

As a result of negative net immigration during the 1890s depression, Australians at the time of Federation were preoccupied about the slow rate of growth of the population. The non-Aboriginal population at the end of 1904 was approximately three and three-quarter million. and the publication in March 1904 of the Report of the New South Wales Royal Commission on the Decline of the Birth Rate and the Mortality of Infants did nothing to allay these concerns. Despite the perceived need for more people. the desire for racial unity was paramount. The main goals of policy makers at the time were to preserve a 'white' and essentially British Australia and create an imperial bastion in the Southern Hemisphere.

Over time, the Immigration Restriction Act of 1901 and its later amendments were remarkably successful in excluding 'coloured' immigrants from Australia.  It is clear, however, that although most Australians wanted to preserve the 'white' and British character of their nation, the argument that 'non-white' and non-British immigrants were more suited to the settlement of northern Australia was frequently debated in the early decades of the twentieth century.  While this idea continued to challenge the validity of a 'white Australia' in the north, public figures were divided on the issue.  This article examines in some detail the contemporary debates over the peopling of the Northern Territory in the inter-war years.

Workforces in individualistic countries, such as the US, the UK and Auslralia, are becoming increasingly culturally diverse. In Australia, the population now comprises people from more than 220 nationalities, approximately 45% of whom were born overseas. It is expected that. by the year 2030, 25% of the Australian population will be of Asian origin Nankervis. Compton, & McCarthy, 1999). Despite large Asian expatriations, the small number of Asian permanent residents in Australia (i.e. 4.7% of 18m people) infers that Asians may be having difficulty fitting into the Australian context. This paper will highlight the unaddressed racial tension in Australian workplaces and discuss the experience of Asian expatriates in light of the racial and value dissimilarity associated with Asian (collectivist) and Australian (individualist) cultures.

This paper investigates the financial disclosure practices of corporate annual reports published in Asian countries including Bangladesh, Indonesian, Malaysia and the Middle East countries including Bahrain, Iran, Jordan, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia and Turkey. The purpose of the study is to measure the financial disclosure diversity in these countries, with a view to developing a classification of their similarities and differences in respect to their compliance with International Accounting Standards (IAS). Annual reports of 126 public companies liisted on the countries' stock exchanges are the central data source, supplemented with other relevant information about financial disclosure practices in each country. A disclosure checklist adopted from all IASs and summarised in 306 individual items of financial disclosures is used as a means of extending an understanding of financial reporting in these countries. Results show the relative degree of conformity with IASs for each of the countries included in this study.

This article examines stories published around the beginning of the twentieth century depicting Asian invasions of Australia, and discovers consistent patterns of gendered and racialised assumptions setting Australian men, the bush and the future of the white race against Australian women, the city, and the asianisation of the nation. It argues that warrior Japan created a powerful case for an answering tradition of defiant, bush-based masculinity in Australia.

Asia dominates global aquaculture production accounting for over 80% of the total and the mainstay in Asian aquaculture is finfish. Over the years, Asia has experienced a number of inter-continental and intra-continental transfers/introductions/translocation of finfish species, between nations and watersheds, beyond their natural range of distribution, primarily for aquaculture development. In this article all such species are referred to as alien species. An attempt is made to evaluate the importance of the production of alien species in selected Asian nations, using statistics of the Food and Agriculture Organization. Also, negative effects, if any, based on literature surveys, of alien species in relation to displacement of indigenous species, and on biodiversity and/or genetic diversity together with associated pathogen transfers are evaluated. The major alien species, based on their significance to Asian inland aquaculture considered, are the tilapias, catfish, Chinese and Indian major carps and common carp. It is estimated that currently alien species account for nearly 12% of the cultured finfish production (2.6 million tonnes) in Asia, valued at US$ 2.59 billion, and the contribution exceeds 40% when Asian countries excluding China are taken into consideration. Inland finfish aquaculture in some Asian nations, such as Indonesia and the Philippines, is predominated by alien species, and in some others, e.g. Bangladesh and India, the contribution from alien species has been increasing steadily. It is suggested that overall alien finfish species have done little ecological harm to native flora and fauna. However, in the wake of increasing anthropogenic development taking place in watersheds the resulting environments are often made unconducive to indigenous species but not to some alien species, thereby potentially and indirectly making the latter invasive.

This article argues that while the US alliance remains at the forefront of Australian security policy, the deepening of ties between the United States and Australia has the potential to complicate Australia's relations with its Southeast asian neighbours. Moreover, the manner in which the Howard government has attempted to manage this shift in policy has only exacerbated the problem. Australian pronouncements of support for the US policy of pre-emption, the perceived preference of the Australian Prime Minister to take on the role of ‘Deputy Sheriff’, and the unwieldy approach taken by the Australian government in policy announcements pertaining to maritime and security policy have caused unnecessary tension and mistrust between Australia and some Southeast asian states.

Babies born in Britain to women of South Asian ethnic origin are lighter on average than the offspring of women of European origin. The causes have been incompletely elucidated but nutritional factors, low socioeconomic status and maternal pre-pregnancy weight have been implicated. This health inequality has received little policy prioritization in Britain. As further research clarifies reasons for this differential, appropriately targeted preventive strategies need to be implemented.

This paper investigates the financial disclosure practices of corporate annual reports published in Asian countries including Bangladesh, Indonesian, Malaysia and the Middle East countries including Bahrain, Iran, Jordan, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia and Turkey. The purpose of the study is to measure the financial disclosure diversity in these countries, with a view to developing a classification of their similarities and differences in respect to their compliance with International Accounting Standards (IASs). Annual reports of 132 public companies listed on the relevant countries stock exchanges are the central data source, supplemented with other reliable information about financial disclosure practices in each country. A disclosure checklist adopted from all IASs and summarised in 306 individual items of financial disclosures is used as a means of extending an understanding of financial reporting literature. Additionally, it provides an indication of voluntary progress towards harmonisation of international accounting practices in several Asian and Middle Eastern countries. Results show the degree of conformity with IASs from less to high conformity is: Saudi Arabia, Qatar, Bangladesh, Iran, Bahrain, Jordan, Pakistan, Oman, Turkey, Malaysia, Kuwait and Indonesia.
