Families are at the core of Australia's social fabric. Understanding their dynamics assists in developing good policies and mechanisms to support them. Repartnering is an important aspect of current-day family dynamics. Yet we know relatively little about how these partnerships operate. This project will illuminate the patterns and issues central to repartnering and provide a significant contribution to social research. Results from this study will equip policy makers with appropriate knowledge to develop policies aimed at assisting families. The findings will contribute to growing international knowledge on family dynamics in repartnered relationships, as well as strengthen Australia's social and economic fabric through stronger families.Read moreRead less
Do Australian parents want both a son and a daughter? From the late 1990s, policy makers became more aware of the importance of fertility in influencing population age structure and growth rates in Australia. The proposed project will augment our understanding of fertility dynamics both current, and over high and low fertility regimes. It will also highlight an important factor in fertility decision-making. There is considerable speculation on the impact of shifting gender-role attitudes on sex ....Do Australian parents want both a son and a daughter? From the late 1990s, policy makers became more aware of the importance of fertility in influencing population age structure and growth rates in Australia. The proposed project will augment our understanding of fertility dynamics both current, and over high and low fertility regimes. It will also highlight an important factor in fertility decision-making. There is considerable speculation on the impact of shifting gender-role attitudes on sex preference, but evidence supporting this is mixed. By developing a deeper understanding of the factors influencing progression to having more children we will be better able to predict fertility trends and provide support to Australian parents.

Mechanisms of manchette function. This project aims to define the function of the manchette, a poorly understood microtubule-based structure present in haploid male germ cells. This project aims to define key mechanisms underpinning manchette development and movement, and to generate a detailed picture of the dynamics of germ cell development using imaging technologies and unique animal models. Such knowledge should improve the understanding of how male fertility is achieved, the origin of infer ....Mechanisms of manchette function. This project aims to define the function of the manchette, a poorly understood microtubule-based structure present in haploid male germ cells. This project aims to define key mechanisms underpinning manchette development and movement, and to generate a detailed picture of the dynamics of germ cell development using imaging technologies and unique animal models. Such knowledge should improve the understanding of how male fertility is achieved, the origin of infertility and how species-specific differences in sperm form are achieved. Such insights may ultimately lead to improved agricultural efficiencies and job creation.Read moreRead less
Family Formation and Fertility Decline in Nineteenth-Century Tasmania. The fertility decline which began across the industrialised world in the late nineteenth century greatly impacted the demographic, economic and social milieux of the twentieth century and beyond. Using family reconstitution techniques and a wide range of data, this project will explore the mechanisms by which fertility decline was achieved in nineteenth-century Tasmania and the broader societal influences that brought these m ....Family Formation and Fertility Decline in Nineteenth-Century Tasmania. The fertility decline which began across the industrialised world in the late nineteenth century greatly impacted the demographic, economic and social milieux of the twentieth century and beyond. Using family reconstitution techniques and a wide range of data, this project will explore the mechanisms by which fertility decline was achieved in nineteenth-century Tasmania and the broader societal influences that brought these mechanisms into play. The results will advance our understanding of Australia's evolution over the nineteenth century and into the twentieth century. The research will result in three journal articles, a single-authored monograph and wide public dissemination.Read moreRead less
Maximizing male fertility: the role of CRISP proteins. This project aims to investigate the function of cysteine rich secretory protein (CRISP) family members in fertility. It is expected to generate new knowledge on the role CRISP1 and 4 play in sperm competition in vivo, and thus, evolutionary processes; to define the role seminal plasma CRISPs play in fertility; and identify the mechanism underpinning their biological activities. This will be achieved using a range of innovative, state-of-the ....Maximizing male fertility: the role of CRISP proteins. This project aims to investigate the function of cysteine rich secretory protein (CRISP) family members in fertility. It is expected to generate new knowledge on the role CRISP1 and 4 play in sperm competition in vivo, and thus, evolutionary processes; to define the role seminal plasma CRISPs play in fertility; and identify the mechanism underpinning their biological activities. This will be achieved using a range of innovative, state-of-the-art approaches. Expected outcomes and benefits include an enhanced knowledge of the mechanisms underpinning fertility and infertility, enhanced collaboration and research knowhow, and an evidence base for future applied projects aimed enhancing fertility in agricultural species.Read moreRead less
Childbearing within cohabiting unions in Australia: trends, explanations and comparison. This project will explore the trends and determinants of childbearing within cohabitation in Australia. The project will contribute to our understanding of modern family dynamics and change. By comparison with other countries we will learn more about the policy settings that assist and support couples to realise their family formation plans.
Dissecting the impact of stress on reproduction: Novel peptide mediates inhibitory effects of stress on female reproduction. This research proposal offers a pioneering opportunity to develop treatments that overcome the negative impact of stress on reproduction. Specifically, knowledge generated in this project will be vital in the development of strategic defences against the impact of stress on reproduction. This project fundamentally addresses Research Priority 2: Promoting and maintaining go ....Dissecting the impact of stress on reproduction: Novel peptide mediates inhibitory effects of stress on female reproduction. This research proposal offers a pioneering opportunity to develop treatments that overcome the negative impact of stress on reproduction. Specifically, knowledge generated in this project will be vital in the development of strategic defences against the impact of stress on reproduction. This project fundamentally addresses Research Priority 2: Promoting and maintaining good health. Given that suppression of reproduction by stress occurs in all mammalian species including humans, domestic animals and wildlife, being able to prevent or overcome stress-induced reproductive dysfunction will generate significant health, social, economic and ecological benefits.

Inequality in first family formation in contemporary Australia. The timing and context of Australians' entry into parenthood differs across the socio-economic spectrum. This project investigates the socio-economic disparities in entering parenthood, particularly focusing on education and employment differentials as well as socio-demographic factors such as ethnic and religious background, and experience of family dissolution. Using longitudinal panel data, this project aims to: determine the soc ....Inequality in first family formation in contemporary Australia. The timing and context of Australians' entry into parenthood differs across the socio-economic spectrum. This project investigates the socio-economic disparities in entering parenthood, particularly focusing on education and employment differentials as well as socio-demographic factors such as ethnic and religious background, and experience of family dissolution. Using longitudinal panel data, this project aims to: determine the socio-economic and demographic differentials of inequality in first family formation in Australia; discover how inequality in first family formation has changed since the middle of the 20th Century; and, assess how family-policy regime mediates or exacerbates this inequality.Read moreRead less
