The purpose of this study was to investigate the association between temperament in Australian infants aged 2–7 months and feeding practices of their first-time mothers (n=698). Associations between feeding practices and beliefs (Infant Feeding Questionnaire) and infant temperament (easy-difficult continuous scale from the Short Temperament Scale for Infants) were tested using linear and binary logistic regression models adjusted for a comprehensive range of covariates. Mothers of infants with a more difficult temperament reported a lower awareness of infant cues, were more likely to use food to calm and reported high concern about overweight and underweight. The covariate maternal depression score largely mirrored these associations. Infant temperament may be an important variable to consider in future research on the prevention of childhood obesity. In practice, mothers of temperamentally difficult infants may need targeted feeding advice to minimise the adoption of undesirable feeding practices.

The standard Exeter stem has a length of 150mm with offsets 37.5mm to 56mm. Shorter stems of lengths 95mm, 115mm and 125mm with offsets 35.5mm or less are available for patients with smaller femurs. Concern has been raised regarding the behaviour of the smaller implants. This paper analysed data from the Australian Orthopaedic Association National Joint Replacement Registry comparing survivorship of stems of offset 35.5mm or less with the standard stems of 37.5mm offset or greater. At seven years there was no significant difference in the Cumulative Percent Revision Rate in the short stems (3.4%, 95% CI 2.4-4.8%) compared with the standard length stems (3.5%, 95% CI 3.3-3.8%) despite its use in a greater proportion of potentially more difficult developmental dysplasia of the hip cases.

Carbon dioxide (CO2), as a primary product of combustion, is a known factor affecting climate change and global warming. In Australia, CO2 emissions from biomass burning are a significant contributor to total carbon in the atmosphere and therefore, it is important to quantify the CO2 emission factors from biomass burning in order to estimate their magnitude and impact on the Australian atmosphere. This paper presents the quantification of CO2 emission factors for five common tree species found in South East Queensland forests, as well as several grasses taken from savannah lands in the Northern Territory of Australia, under controlled ‘fast burning’ and ‘slow burning’ laboratory conditions. The results showed that CO2 emission factors varied according to the type of vegetation and burning conditions, with emission factors for fast burning being 2574 ± 254 g/kg for wood, 394 ± 40 g/kg for branches and leaves, and 2181 ± 120 g/kg for grass. Under slow burning conditions, the CO2 emission factors were 218 ± 20 g/kg for wood, 392± 80 g/kg for branches and leaves, and 2027 ± 809 g/kg for grass.

INTRODUCTION: Little research has examined recognized pregnancy losses in a general population. Data from an Australian cohort study provide an opportunity to quantify this aspect of fecundity at a population level. METHOD: Participants in the Australian Longitudinal Study on Women's Health who were aged 28-33 years in 2006 (n = 9,145) completed up to 4 mailed surveys over 10 years. Participants were categorized according to the recognized outcome of their pregnancies, including live birth, miscarriage/stillbirth, termination/ectopic, or no pregnancy. RESULTS: At age 18-23, more women reported terminations (7%) than miscarriages (4%). By 28-33 years, the cumulative frequency of miscarriage (15%) was as common as termination (16%). For women aged 28-33 years who had ever been pregnant (n = 5,343), pregnancy outcomes were as follows: birth only (50%); loss only (18%); and birth and loss (32%), of which half (16%) were birth and miscarriage. A comparison between first miscarriage and first birth (no miscarriage) showed that most first miscarriages occurred in women aged 18-23 years who also reported a first birth at the same survey (15%). Half (51%) of all first births and first miscarriages in women aged 18-19 ended in miscarriage. Early childbearers (<28 years) often had miscarriages around the same time period as their first live birth, suggesting proactive family formation. Delayed childbearers (32-33 years) had more first births than first miscarriages. CONCLUSION: Recognized pregnancy losses are an important measure of fecundity in the general population because they indicate successful conception and maintenance of pregnancy to varying reproductive endpoints.

OBJECTIVE: To identify the factors associated with infertility, seeking advice and treatment with fertility hormones and/or in vitro fertilisation (IVF) among a general population of women. METHODS: Participants in the Australian Longitudinal Study on Women's Health aged 28-33 years in 2006 had completed up to four mailed surveys over 10 years (n=9,145). Parsimonious multivariate logistic regression was used to identify the socio-demographic, biological (including reproductive histories), and behavioural factors associated with infertility, advice and hormonal/IVF treatment. RESULTS: For women who had tried to conceive or had been pregnant (n=5,936), 17% reported infertility. Among women with infertility (n=1031), 72% (n=728) sought advice but only 50% (n=356) used hormonal/IVF treatment. Women had higher odds of infertility when: they had never been pregnant (OR=7.2, 95% CI 5.6-9.1) or had a history of miscarriage (OR range=1.5-4.0) than those who had given birth (and never had a miscarriage or termination). CONCLUSION: Only one-third of women with infertility used hormonal and/or IVF treatment. Women with PCOS or endometriosis were the most proactive in having sought advice and used hormonal/IVF treatment. IMPLICATIONS: Raised awareness of age-related declining fertility is important for partnered women aged approximately 30 years to encourage pregnancy during their prime reproductive years and reduce the risk of infertility.

In response to a focus on reading, this paper examines the notion of reading online; as such it uses the term ‘networked reading’ to describe any act of reading in an online or digital environment. In accordance with this notion of ‘networked’ reading, the paper provides a broad introduction to AustLit: the Australian Literature Resource. This is followed by an examination of a suite of services and digital tools (LORE) developed by the Aus-e-Lit project that extends the scope of AustLit records and facilitates links to external resources. The focus of the final section of the paper is on a collection of Full Text resources located within the AustLit subset Children’s Literature Digital Resources (CLDR). It proposes a number of ways in which these texts, and an accompanying anthology of critical articles, can be utilised in classrooms across the Primary, Middle and Senior School spectrum.

Intelligence and context, knowledge, competence, and performance and results summarize the content of the papers presented to readers in this issue of the Journal. This is a very relevant series of papers as, for the past 50 years, project management has become a well-accepted way to manage organizations. The field of project management has evolved from operational research techniques and tools to a discipline of management encompassing various schools of thought (Söderlund, 2002; Turner, Huemann, Anbari, & Bredillet, 2010)...

In order to read this Project Management Journal issue, I suggest embracing a modeling perspective. Talking about modeling should lead me to define what is meant by “model” and to develop some kind of categorization, classification, or taxonomy of models. One can consider basic categories like quantitative vs. qualitative, explanatory vs. predictive, stochastic, nonstochastic mathematical, or qualitative models, linear vs. nonlinear and their underlying assumptions, degree of simplification, systemic effects integration, and so on...
