Life history theory predicts that individuals make trade-offs between investment in current reproduction, future reproductive potential and success in order to maximise lifetime reproductive success (LRS). Factors that may influence LRS in seabirds include delayed maturity, small clutches, high adults survivorship and long life spans. Studies have shown that reproductive success of seabirds increases with age and experience. Australasian gannets are long-lived seabirds that typically commence breeding at five or six years of age. A small colony of gannets was monitored over 12 years. This study aimed to identify patterns of long-term individual breeding biology. Results indicate that nest site, pair bond duration, age and breeding experience are all important factors in reproductive success. Relationships were found between breeding success and several variables including breeding experience, pair bond duration and nest site quality. Identifying and understanding the factors that contribute to individuals’ reproductive success is of critical importance for future conservation and management of seabird species.

Inflammatory markers, including serum C-reactive protein (CRP), are predictors of coronary heart disease (CHD) in adults. South Asians in the UK have higher rates of CHD in adulthood than national rates.We tested the hypotheses that South Asian infants would have higher serum concentrations of CRP and homocysteine than European infants up to 2 years of age and that higher infant weight is associated with elevation of inflammatory markers. Infants of South Asian and European origin were investigated in a mixed cross sectional-longitudinal cohort study. Mothers were recruited ante-natally from St Mary’s Hospital,Manchester by postal invitation and telephone call to non-responders. Infants with metabolic or congenital abnormalities, known syndromes or pre-maturity were excluded. Measurements were collected at birth and either 3, 6, 12 or 24 months. High sensitivity CRP and homocysteine were measured by an immulite immunoassay. We used mixed linear modelling to assess whether infant weight, ethnicity, length of follow-up or their interaction were associated with inflammatory makers in infants during follow-up. Data are presented on 306 infants (109 South Asian and 197 European). We found that European infants had higher serum CRP than South Asian infants during follow-up which was of borderline significance.There was no difference in serum homocysteine between ethnic groups during followup and no significant interaction between ethnicity and follow-up. Infant weight was significantly associated with CRP but not homocysteine. In this ongoing longitudinal study,we found little difference in inflammatory markers in infants from birth to 2 years despite markedly higher rates of CHD in South Asian than European adults. Life course exposure to risk factors may play a more dominant role in the development of CHD.

Background: This article aims to examine the relative contribution of occupational activity to English adults’ meeting of government recommendations for physical activity (PA).

Methods: Data were extracted from a cross-sectional survey of householders in the UK via the Health Survey for England.1 In total, 14,018 adult participants were included in the analysis. Multivariate logistic regression was used to examine the odds of achieving PA recommendations with and without including occupational activity and to examine the contribution of gender and social and demographic characteristics.

Results: When occupational PA was included, 36% of men and 25% of women were active at the recommended level. Once occupational PA was removed, these proportions were 23% and 19%, respectively. These results were socially patterned, most notably by age and gender.

Conclusions: Occupational PA provides a substantial contribution to those meeting the government target for PA.

Background
Efforts to prevent the development of overweight and obesity have increasingly focused early in the life course as we recognise that both metabolic and behavioural patterns are often established within the first few years of life. Randomised controlled trials (RCTs) of interventions are even more powerful when, with forethought, they are synthesised into an individual patient data (IPD) prospective meta-analysis (PMA). An IPD PMA is a unique research design where several trials are identified for inclusion in an analysis before any of the individual trial results become known and the data are provided for each randomised patient. This methodology minimises the publication and selection bias often associated with a retrospective meta-analysis by allowing hypotheses, analysis methods and selection criteria to be specified a priori.

Methods/Design
The Early Prevention of Obesity in CHildren (EPOCH) Collaboration was formed in 2009. The main objective of the EPOCH Collaboration is to determine if early intervention for childhood obesity impacts on body mass index (BMI) z scores at age 18-24 months. Additional research questions will focus on whether early intervention has an impact on children's dietary quality, TV viewing time, duration of breastfeeding and parenting styles. This protocol includes the hypotheses, inclusion criteria and outcome measures to be used in the IPD PMA. The sample size of the combined dataset at final outcome assessment (approximately 1800 infants) will allow greater precision when exploring differences in the effect of early intervention with respect to pre-specified participant- and intervention-level characteristics.

Discussion
Finalisation of the data collection procedures and analysis plans will be complete by the end of 2010. Data collection and analysis will occur during 2011-2012 and results should be available by 2013.

Youth and risk are artefacts of expertise, constructed at the intersection of a wide range of knowledges about Youth and so-called Youth issues: an intersection marked by institutionalised, scientific representations of education, family, the life course, risk, and so on. In this paper I suggest that the messiness of human experiences and existence requires knowledge practices in the social sciences that can rethink what counts as truth. These interests – which are grounded in the knowledge practices that frame the work being undertaken in a large scale, qualitative investigation of the cultural drivers shaping the alcohol practices of 14 to 24 year old Australian’s - will be addressed through a discussion of the ways in which Tim Winton’s (2008) new novel Breath can be read as an allegorical tale about the terror of being ordinary: and of the teenage years as being a time in a life in which the fear of being ordinary compels Winton’s key characters to seek out, sometimes stumble upon, and embrace that which promises to make their’s a life less ordinary. In these recollections risk is something that breathes energy and purpose into lifeworlds that are dominated by the institutionalised ordinariness of family, school, and work.

The initial development of the Internet and the World Wide Web was based upon the presentation of static information, this only allowed for the access and consumption of that information. The development of Web 2.0 has resulted in a situation where information is displayed in a dynamic manner and allows for interaction between the viewer and the site or application showing this information. The information may no longer just be text based but could be video, audio and information presented in an interactive manner though applications.

The terms terrorist or terrorism are highly emotive terms but the general term, terrorist, is used to denote revolutionaries who seek to use terror systematically to further their views or to govern a particular area. Terrorist organisations are reflective and adoptive, this paper focus on the impact of Web 2.0 and its potential use by terrorist organisations. The paper uses real life case studies to identify the key issues and possible trends.

The increasingly diverse needs and wants of Australia's ageing population, like those in many other societies, are drawing attention to aged care as an increasingly important area of broader health and social policy. Active qgeing and a focus on enabling people to remain living in their own homes in the community are two of the key components of this policy shift.

The policy shift towards active ageing recognises and aims to support the desires of older people to remain active members of their communities as they age. Active ageing is 'the process of optimising opportunities for physical, social and mental wellbeing throughout the life-course, in order to extend healthy life expectancy, productivity and quality oflife in older age' (AIPC 2008: 26).

According to the World Health Organization (WHO), the rights, needs, preferences and capacities of older people should be central to active ageing policies, and these should be framed by a life-course approach to ageing (WHO 2002). The development of age-friendly communities, social inclusion and engagement are emerging as key policy issues in the context of an ageing population.

Recent research demonstrates the importance of a sense of belonging in maintaining a sense of identity and increasing the wellbeing of an individual. The sense of belonging that comes about through community engagement also plays a role in successful adjustment to ageing, including prolonging good health and reduced risk of entry into residential aged care.

Book review: This book has much to offer social work and human services students. It covers many key theories, ideas, and debates relevant to a wide range of practice fields in a comprehensive, clearly organised, and engaging fashion. The author proposes, as on overarching premise, a “multidimensional” approach to understanding lifespan development and experiences of trauma, stress, and grief, as well as responses of adaptation and resilience across the life course. Consistent with social work values, the multidimensional approach “places an emphasis on the constant interaction of the biological, psychological, and spiritual dimensions of our inner worlds with the relational, social, structural, and cultural dimensions of our outer worlds” (p. 394).

Self-assessment of support needs is a relatively new and under-researched phenomenon in domiciliary aged care. This article outlines the results of a comparative study focusing on whether a self-assessment approach assists clients to identify support needs and the degree to which self-assessed needs differ from an assessment conducted by community care professionals. A total of 48 older people and their case managers completed a needs assessment tool. Twenty-two semi-structured interviews were used to ascertain older people’s views and preferences regarding the self-assessment process. The study suggests that while a co-assessment approach as outlined in this article has the potential to assist older people to gain a better understanding of their care needs as well as the assessment process and its ramifications, client self-assessment should be seen as part of a co-assessment process involving care professionals. Such a co-assessment process allows older people to gain a better understanding of their support needs and the wider community aged care context. The article suggests that a co-assessment process involving both clients and care professionals contains features that have the capacity to enhance domiciliary aged care.

Aims: Susceptibility to food insecurity can vary over a life course; however, a potential period of particular vulnerability is while studying at a tertiary institution. This pilot study aimed to assess the prevalence, severity and potential determinants of food insecurity among tertiary students attending a Victorian-based institution. Methods: The present study employed a cross-sectional design, involving use of a self-reported questionnaire. The survey, conducted in 2012, was administered to a sample of 124 Deakin University students and contains measures of food insecurity status, demographics and other potential explanatory factors. Descriptive and regression analysis was undertaken to investigate the prevalence of food insecurity and associations with factors that may support or hinder a student's ability to procure food, such as living arrangements, income and knowledge of support services. Results: Food insecurity without hunger was reported by 18% of Deakin University students, while an additional 30% reported experiencing the more severe form of food insecurity (with hunger). A lower odds of being food insecure was reported among students living with their family (without hunger OR 0.35; 95% CI 0.12-0.99; with hunger OR 0.29; 95% CI 0.12-0.70), while a higher odds was found among those receiving government support (with hunger OR 2.52; 95% CI 1.05-6.04). Conclusions: The reported prevalence of food insecurity among the tertiary student sample was greater than the general Australian population, suggesting they are a vulnerable group. This may be attributable to financial pressures faced when students are not living with their parents.

BACKGROUND: Overweight, obesity and excess gestational weight gain (GWG) are associated with negative health outcomes for mother and child in pregnancy and across the life course. Interventions promoting GWG within guidelines report mixed results. Most are time and cost intensive, which limits scalability. Mobile technologies (mHealth) offer low cost, ready access and individually-tailored support. We aim to test the feasibility of an mHealth intervention promoting healthy nutrition, physical activity and GWG in women who begin pregnancy overweight or obese. METHODS/DESIGN: txt4two is a parallel randomised control trial pilot recruiting women with a singleton, live gestation between 10(+0) and 17(+6) weeks at the first hospital antenatal clinic visit. Inclusion criteria are pre-pregnancy BMI > 25 kg/m(2) and mobile phone ownership. One hundred consenting women will be randomised to intervention or control groups at a 1:1 ratio. All participants will receive standard antenatal care. In addition, the txt4two intervention will be delivered from baseline to 36 weeks gestation and consists of a tailored suite of theoretically-grounded, evidence-based intervention strategies focusing on healthy nutrition, physical activity and GWG. This includes: mobile phone interactive text messages promoting positive health behaviours, goal setting and self-monitoring; video messages; an information website; and a private moderated Facebook® chat forum. The primary outcome is the feasibility of the intervention. Secondary outcomes include GWG and participants' knowledge and behaviour regarding diet and physical activity during pregnancy. DISCUSSION: Findings will inform the development of larger-scale mHealth programmes to improve the delivery of healthy pregnancy nutrition, physical activity and GWG, that could be widely translated and disseminated. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry: ACTRNU111111544397 . Date of registration: 19 March 2014.

INTRODUCTION: Early childhood is an important period for establishing behaviours that will affect weight gain and health across the life course. Early feeding choices, including breast and/or formula, timing of introduction of solids, physical activity and electronic media use among infants and young children are considered likely determinants of childhood obesity. Parents play a primary role in shaping these behaviours through parental modelling, feeding styles, and the food and physical activity environments provided. Children from low socio-economic backgrounds have higher rates of obesity, making early intervention particularly important. However, such families are often more difficult to reach and may be less likely to participate in traditional programs that support healthy behaviours. Parents across all socio-demographic groups frequently access primary health care (PHC) services, including nurses in community health services and general medical practices, providing unparalleled opportunity for engagement to influence family behaviours. One emerging and promising area that might maximise engagement at a low cost is the provision of support for healthy parenting through electronic media such as the Internet or smart phones. The Growing healthy study explores the feasibility of delivering such support via primary health care services.

METHODS: This paper describes the Growing healthy study, a non-randomised quasi experimental study examining the feasibility of an intervention delivered via a smartphone app (or website) for parents living in socioeconomically disadvantaged areas, for promoting infant feeding and parenting behaviours that promote healthy rather than excessive weight gain. Participants will be recruited via their primary health care practitioner and followed until their infant is 9 months old. Data will be collected via web-based questionnaires and the data collected inherently by the app itself.

ETHICS AND DISSEMINATION: This study received approval from the University of Technology Sydney Ethics committee and will be disseminated via peer-reviewed publications and conference presentations.
