The infant feeding practices of Chinese immigrant mothers in Australia: A qualitative exploration

BACKGROUND: The Australian Infant Feeding Guidelines recommend exclusive breastfeeding until about six months of age when solid foods should be gradually introduced. Evidence indicates that Chinese immigrant mothers in Australia are more likely to use infant formula in combination with breastfeeding and to introduce solids earlier than the general Australian population. This study aimed to explore Chinese immigrant mother's experiences of feeding their infant to gain an insight into the factors shaping their feeding decisions and perceptions of infant growth. METHODS: Semi structured interviews were conducted with 36 Chinese immigrant mothers with children aged 0-12 months, living in Melbourne, Australia. Interviews were conducted either in Chinese, using an interpreter, or in English. All were audio recorded. Recordings were transcribed verbatim and thematically analysed. RESULTS: Eight themes were identified. Chinese immigrant mothers were supportive of exclusive breastfeeding, however breastfeeding problems and conflicting views about infant feeding and infant growth from grandparents reduced many mothers' confidence to breastfeed exclusively. For many new mothers, anxiety that exclusive breastfeeding provided insufficient nourishment led to the introduction of formula before six months of age. Most mothers delayed introducing solid food to five to six months to prevent development of allergic diseases and gastrointestinal problems. Chinese immigrant mothers obtained information and support related to infant feeding from a combination of health professionals, online resources, friends and grandparents. CONCLUSIONS: Chinese immigrant mothers in Australia need support to breastfeed exclusively. In particular maternal confidence to breastfeed exclusively needs to be increased. To achieve this, culturally sensitive guidance is needed and the contradictions in advice given by Chinese grandparents and health professionals on infant feeding practices and healthy infant growth need to be recognised and addressed.

Overcoming barriers to the reuse of construction waste material in Australia: a review of the literature

Although much has been written on how to improve the management of construction waste and increase the use of recycled materials, little progress has been made to address the reuse of construction waste. Yet there is a consensus in the literature that waste reuse practices have a decisive role to play in improving reduction of waste, and that institutional barriers are the most problematic obstacles to implementing identified reuse strategies. This paper examines the literature from the last 10 years on the issues facing different stakeholders around reuse of construction waste in Australia, and the causes and effects of the institutional barriers encountered. Key texts from before this period are also referenced. The findings reveal that institutional impediments are related to problems outside of the construction industry, such as social, economic and political barriers to change. A number of constraints are identified: lack of interest and demand from clients; attitudes towards reuse practices; and training all of which act as disincentives to a proactive and sustainable application of construction waste reuse strategies. Above all, it is argued that legislation should be better implemented to ensure that all states in Australia are required to implement strategies to reuse waste construction materials.

Australia, Korea and the Korean Question in the United Nations, 1946-1991

One previously unrecognised feature of the history of the political relationship between Australia and Korea is the role played by Australia as a member of the United Nations Organization in respect to the so-called Korea Question. Drawing on source documents from UN Resolutions and Australian Archives this article examines the changing positions of Australia as the Korea Question developed in the UN General Assembly. This spanned a period from the beginnings of the UN Organization until the time when both Koreas were admitted as members in 1991. The article proposes the Australian positions as responses to changing domestic and international political contexts.

Members abroad - Australia - Brisbane and the Gold Coast

Brisbane's sub-tropical climate, vegetation and urban history as a British settlement, endow the region with many characteristics that are familiar in KwaZulu-Natal. Brisbane settlement, firstly as a penal conlony to accommodate the hardiest criminals dispatched from Sydney, was established in 1825 on a wide river, several kilometers upstream from Moreton Bay with the Pacific Ocean beyond. The penal colony was short lived and was soon opened up to free settlement in 1842. The growth of the fledgling town was characterized by brick warehouse and service buildings to the port that was established on its riverbanks, resembling those of the old Point Road area in Durban. Government and administration buildings heralded Brisbane as the captial city of the State of Queensland, annexed from New South Wales in 1859. Morphological studies reveal that Brisbane had reached its first zenith around 1930 as a commerical city of four and five storey buildings. The urban form remained stagnant until the post-1960's building boom and the developments from this period on, consolidated land amalgamations largely ignoring the urban characteristics of the established city. Public space was poorly observed, resulting in a city that had turned its back on the river. It is only in recent times that the currency of good urban design, under the custodial direction of the City Council, has fostered a re-engagemed urban realm that, enabled by the recent building boom, has delivered high quality urban environments

Prehistoric hand stencils at Fern Cave, North Queensland (Australia): environmental and chronological implications of Raman spectroscopy and FT-IR imaging results

Raman spectroscopy and FT-IR imaging analyses of cave wall pigment samples from north Queensland (Australia) indicate that some hand stencils were undertaken during a dry environmental phase indicating late Holocene age. Other, earlier painting episodes also took place during dry environmental periods of the terminal Pleistocene and/or early Holocene. These results represent a rare opportunity to attain chronological information for rock art in conditions where insufficient carbon is present for radiocarbon dating.

Discovery and characterization of IGFBP-mediated endocytosis in the human retinal pigment epithelial cell line ARPE-19

Insulin-like growth factor binding proteins (IGFBPs) are prime regulators of IGF-action in numerous cell types including the retinal pigment epithelium (RPE). The RPE performs several functions essential for vision, including growth factor secretion and waste removal via a phagocytic process mediated in part by vitronectin (Vn). In the course of studying the effects of IGFBPs on IGF-mediated VEGF secretion and Vn-mediated phagocytosis in the RPE cell line ARPE-19, we have discovered that these cells avidly ingest synthetic microspheres (2.0 μm diameter) coated with IGFBPs. Given the novelty of this finding and the established role for endocytosis in mediating IGFBP actions in other cell types, we have explored the potential role of candidate cell surface receptors. Moreover, we have examined the role of key IGFBP structural motifs, by comparing responses to three members of the IGFBP family (IGFBP-3, IGFBP-4 and IGFBP-5) which display overlapping variations in primary structure and glycosylation status. Coating of microspheres (FluoSpheres®, sulfate modified polystyrene filled with a fluorophore) was conducted at 37 °C for 1 h using 20 μg/mL of test protein, followed by extensive washing. Binding of proteins was confirmed using a microBCA assay. The negative control consisted of microspheres treated with 0.1% bovine serum albumin (BSA), and all test samples were post-treated with BSA in an effort to coat any remaining free protein binding sites, which might otherwise encourage non-specific interactions with the cell surface. Serum-starved cultures of ARPE-19 cells were incubated with microspheres for 24 h, using a ratio of approximately 100 microspheres per cell. Uptake of microspheres was quantified using a fluorometer and was confirmed visually by confocal fluorescence microscopy. The ARPE-19 cells displayed little affinity for BSA-treated microspheres, but avidly ingested large quantities of those pre-treated with Vn (ANOVA; p < 0.001). Strong responses were also observed towards recombinant formulations of non-glycosylated IGFBP-3, glycosylated IGFBP-3 and glycosylated IGFBP-5 (all p < 0.001), while glycosylated IGFBP-4 induced a relatively minor response (p < 0.05). The response to IGFBP-3 was unaffected in the presence of excess soluble IGFBP-3, IGF-I or Vn. Likewise, soluble IGFBP-3 did not induce uptake of BSA-treated microspheres. Antibodies to either the transferrin receptor or type 1 IGF-receptor displayed slight inhibitory effects on responses to IGFBPs and Vn. Heparin abolished responses to Vn, IGFBP-5 and non-glycosylated IGFBP-3, but only partially inhibited the response to glycosylated IGFBP-3. Our results demonstrate for the first time IGFBP-mediated endocytosis in ARPE-19 cells and suggest roles for the IGFBP-heparin-binding domain and glycosylation status. These findings have important implications for understanding the mechanisms of IGFBP actions on the RPE, and in particular suggest a role for IGFBP-endocytosis.

Research training and national innovation systems in Australia, Finland and the United States : a policy and systems study supported by 30 case studies of research students in the fields of geospatial science, wireless communication, biosciences, and materials science and engineering

Reforms to the national research and research training system by the Commonwealth Government of Australia sought to effectively connect research conducted in universities to Australia's national innovation system. Research training has a key role in ensuring an adequate supply of highly skilled people for the national innovation system. During their studies, research students produce and disseminate a massive amount of new knowledge. Prior to this study, there was no research that examined the contribution of research training to Australia's national innovation system despite the existence of policy initiatives aiming to enhance this contribution. Given Australia's below average (but improving) innovation performance compared to other OECD countries, the inclusion of Finland and the United States provided further insights into the key research question. This study examined three obvious ways that research training contributes to the national innovation systems in the three countries: the international mobility and migration of research students and graduates, knowledge production and distribution by research students, and the impact of research training as advanced human capital formation on economic growth. Findings have informed the concept of a research training culture of innovation that aims to enhance the contribution of research training to Australia's national innovation system. Key features include internationally competitive research and research training environments; research training programs that equip students with economically-relevant knowledge and the capabilities required by employers operating in knowledge-based economies; attractive research careers in different sectors; a national commitment to R&D as indicated by high levels of gross and business R&D expenditure; high private and social rates of return from research training; and the horizontal coordination of key organisations that create policy for, and/or invest in research training.

Entrepreneurial discovery and exploitation processes : sequence or symbiosis?

This study examined the effect that temporal order within the entrepreneurial discovery-exploitation process has on the outcomes of venture creation. Consistent with sequential theories of discovery-exploitation, the general flow of venture creation was found to be directed from discovery toward exploitation in a random sample of nascent ventures. However, venture creation attempts which specifically follow this sequence derive poor outcomes. Moreover, simultaneous discovery-exploitation was the most prevalent temporal order observed, and venture attempts that proceed in this manner more likely become operational. These findings suggest that venture creation is a multi-scale phenomenon that is at once directional in time, and simultaneously driven by symbiotically coupled discovery and exploitation.
