The committee recommends that public consultation be undertaken regarding the introduction of mitochondrial donation to Australian clinical practice. To facilitate this consultation, the committee further recommends the Australian Government prepare a consultation paper, including options for legislative change that would be required. The Minister for Health should seek advice from the National Health and Medical Research Council on the most appropriate timing and format for this consultation. Recommendation 2 5.100 The committee recommends that the Australian Government task the National Health and Medical Research Council with advising on the following questions: • Whether mitochondrial donation is distinct from germline genetic modification. • Is there any new information to indicate that research findings from the United Kingdom, that the science of mitochondrial donation is safe for introduction into controlled clinical practice, cannot be applied in an Australian context? • Whether other approaches to inheriting mitochondrial disease should also be the focus of Australian research. 5.101 The committee recommends the findings be used to inform future legislative process. Recommendation 3 5.103 The committee recommends the Minster for Health take the findings of this report to the Council of Australian Governments (COAG) Health Council to progress the implementation of this report's recommendations with the states and territories. Recommendation 4 5.104 The committee recommends, noting the need for community consultation and scientific review, the urgency of treatment for current patients and the small number of patients seeking this treatment, that the Australian Government initiate dialogue with the relevant authorities in the United Kingdom to facilitate access for Australian patients to the United Kingdom treatment facility as an interim measure. x Chapter 1 Introduction 1.1 Mitochondrial donation is a reproductive technology procedure to reduce the chances of a woman passing on mitochondrial disease—a potentially life-threatening condition—to her children. 1.2 Mitochondrial donation was legalised for use on humans in the United Kingdom (UK) in 2015.

As a result, more and more children are growing up without the support of both parents, and this may be causing developmental consequences. While there has been significant research conducted on the effect of absent fathers on children in general, there has been far less research regarding girls specifically. As discovered in this paper, girls are often impacted differently than boys when it comes to growing up without a father. The current research paper aims to discover just exactly how girls are impacted by this lack of a parent throughout their lifetimes, from birth to adulthood.

MATRIFOCALITY AND WOMEN'S POWER ON THE MISKITO COAST1 Laura Hobson Herlihy University of Kansas Miskitu women in the village of Kuri (northeastern Honduras) live in matrilocal groups, while men work as deep-water lobster divers. Data reveal that with the long-term presence of the international lobster economy, Kuri has become increasingly matrilocal, matrifocal, and matrilineal. Female-centered social practices in Kuri represent broader patterns in Middle America caused by indigenous men's participation in the global economy. Indigenous women now play heightened roles in preserving cultural, linguistic, and social identities. (Gender, power, kinship, Miskitu women, Honduras) Along the Miskito Coast of northeastern Honduras, indigenous Miskitu men have participated in both subsistence-based and outside economies since the colonial era. For almost 200 years, international companies hired Miskitu men as wage- laborers in "boom and bust" extractive economies, including gold, bananas, and mahogany.

It also aimed to return information to the knowledge holders for the purposes of strengthening Aboriginal ways of knowing, being and doing. This study is presented as a journey, with the oral story-telling traditions of the Larrakia and Warumungu embedded and laced throughout. The kinship system is unpacked in detail, and knowledge holders explain its benefits in their lives along with their support for sharing this knowledge with social workers.

  • Muang Matrifocality
    MUANG MATRIFOCALITY by Richard Davis* The rural Muang (Yuan, Northern Thai), who inhabit the lowland areas of the northernmost provinces of Thailand and number over three million people, exhibit a social structure dominated by female ties. The two salient features of this social structure are a mandatory initial period of matrilocal residence, and matriclan organization. Both of these principles are reflected in the structure of the typical Muang dwelling. The most important component of a Muang house, and the part most hedged with taboos regarding its use, construction and location, is that part called the huan (hidn). The huan area of the house comprises the sleeping area, plus an open chamber called the tern (t;;;)n) which serves as a reception area for guests in the daytime and evenings and as the sleeping quarters for unmarried males at night. The sleeping area of most present-day houses is composed of two chambers delimited by the position of the houseposts. The household head and his wife and small children sleep in the chamber nearest the tern. The other cham­ ber is for unmarried daughters or a married daughter and son-in-law. In former times the sleeping area was larger, containing more chambers to house several married daughters and their husbands. The invisible bipartition of the enclosed part of the huan into two chambers, one for the household head and his wife and one for their married daughter and son-in-law, mirrors an important and distinctive feature of the Muang residence pattern. In rural Nan there is an obli­ gatory initial period of matrilocal residence, which usually lasts a year or more.
