Obesity prevention programs and policies: practitioner and policy-maker perceptions of feasibility and effectiveness

Objectives:

Thermosets : structure, properties and applications

Structure-property relationships of thermosets are important in the manufacture and application of materials. Understanding the desired properties of a material in a certain application is related to the material's structure and vice versa. The way in which the material is processed is also a determinant of the structure and resulting properties. Many books have been written about the chemistry of thermosets but with only brief consideration of structure-property relationships. This book focuses on how the structure and properties of a range of thermosets affect the final material and applications. It is composed of two parts: I Structure and properties of thermosets and II Applications of thermosets. Part I starts with a comprehensive overview of thermosets covering structure, properties and processing for advanced applications, followed by four chapters addressing mechanical properties, thermal properties, rheology, and nanostructures and toughening. The applications presented in Part II range from the use of thermosets in the building and construction industry to aerospace applications, electrical applications, thermoset adhesives and insulation materials in appliances and other applications. We hope that this book will not only be a useful textbook for advanced undergraduate and postgraduate students, but also a concise reference for researchers in academia and engineers in related industries. I would like to express my sincere gratitude to the staff of Woodhead Publishing Limited, especially Kathryn Picking who invited me to edit this book and helped develop the initial content, also Adam Hooper, Helen Bradley, Emily Cole, Francis Dodds and Rachel Cox for their assistance in many ways during the preparation of the manuscript. Finally, I wish to express my appreciation and respects to all the contributors for their commitment, patience and pleasant cooperation.

Capacity-building in nonprofit organizations : Is there a blended learning paradigm for the sector?

Blended learning models are widely-used, successful training vehicles for e-learning and workplace training, in corporate as well as higher education environments. Increasingly, Web 2.0 applications, imbedded within blended learning models, are being recognized for their utility in these settings. Concern for the sustainability and relevance of nonprofit organizations has sharpened the interest in building effective capacity-building models for the sector. Can Web 2.0 technologies enhance capacity-building models in the Third Sector? Because blended learning is a remarkably adaptable and fluid model, its potential for transforming capacity-building models in the nonprofit sector is thought to be significant. This paper introduces the concept of transformational approaches to capacity-building and asks if blended learning paradigms that incorporate interactive next-generation technologies might strike a responsive chord in the sector. The authors present research to date on blended learning and capacity-building to lay the foundation for the introduction of one blended learning model for training and education in the nonprofit sector. While the authors suggest that blended learning, as it is evolving, is the key to driving innovation in capacity-building models, they recognize that tailoring blended learning to the audience is critical in achieving success. It is suggested that for optimal results, capacity-building efforts should be built on holistic approaches to the integration of individual self-actualization goals with mechanisms for organizational and sector empowerment, using the technologies imbedded with blended learning. © 2011 Springer-Verlag.

The impact of interventions to prevent obesity or improve obesity related behaviours in children (0-5 years) from socioeconomically disadvantaged and/or indigenous families: a systematic review

Background
Children from disadvantaged families including those from low socioeconomic backgrounds and Indigenous families have higher rates of obesity, making early intervention a priority. The aim of this study was to systematically review the literature to examine the effectiveness of interventions to prevent obesity or improve obesity related behaviours in children 0-5 years from socioeconomically disadvantaged or Indigenous families.

Methods
Searches of major electronic databases identified articles published from 1993–2013 targeting feeding practices, anthropometric, diet, activity or sedentary behaviour outcomes. This was supplemented with snowballing from existing reviews and primary studies. Data extraction was undertaken by one author and cross checked by another. Quality assessments included both internal and external validity.

Results
Thirty-two studies were identified, with only two (both low quality) in Indigenous groups. Fourteen studies had a primary aim to prevent obesity. Mean differences between intervention and control groups ranged from -0.29 kg/m2 to -0.54 kg/m2 for body mass index (BMI) and -2.9 to -25.6% for the prevalence of overweight/obesity. Interventions initiated in infancy (under two years) had a positive impact on obesity related behaviours (e.g. diet quality) but few measured the longer-term impact on healthy weight gain. Findings amongst pre-schoolers (3–5 years) were mixed, with the more successful interventions requiring high levels of parental engagement, use of behaviour change techniques, a focus on skill building and links to community resources. Less than 10% of studies were high quality. Future studies should focus on improving study quality, including follow-up of longer-term anthropometric outcomes, assessments of cost effectiveness, acceptability in target populations and potential for implementation in routine service delivery.

Conclusion
There is an urgent need for further research on effective obesity prevention interventions for Indigenous children. The findings from the growing body of intervention research focusing on obesity prevention amongst young children from socioeconomically disadvantaged families suggest intervention effects are modest but promising. Further high quality studies with longer term follow up are required.

Muscle strength and areal bone mineral density at the hip in women: a cross-sectional study

BACKGROUND: Muscle strengthening exercises are promoted for building and maintaining a healthy skeleton. We aimed to investigate the relationship between muscle strength and areal bone mineral density (BMD) at the hip in women aged 26-97 years.

METHODS: This cross-sectional study utilises data from 863 women assessed for the Geelong Osteoporosis Study. Measures of hip flexor and abductor strength were made using a hand-held dynamometer (Nicholas Manual Muscle Tester). The maximal measure from three trials on each leg was used for analyses. BMD was measured at the hip using dual energy x-ray absorptiometry (DXA; Lunar DPX-L). Total lean mass, body fat mass and appendicular lean mass were determined from whole body DXA scans. Linear regression techniques were used with muscle strength as the independent variable and BMD as the dependent variable. Models were adjusted for age and indices of body composition.

RESULTS: Measures of age-adjusted hip flexor strength and hip abductor strength were positively associated with total hip BMD. For each standard deviation (SD) increase in hip flexor strength, the increase in mean total hip BMD (SD) was 10.4 % (p = 0.009). A similar pattern was observed for hip abductor strength, with an increase in mean total hip BMD of 22.8 % (p = 0.025). All associations between hip muscle strength and total hip BMD were independent of height, but were nullified after adjusting for appendicular lean mass or total lean mass.

CONCLUSIONS: There was a positive association observed between muscle strength and BMD at the hip. However, this association was explained by measures of lean mass.

Composition of fuel stores and digestive limitations to fuel deposition rate in the long-distance migratory thrush nightingale, Luscinia luscinia

During their autumn migratory phase, thrush nightingales (Luscinia luscinia) previously starved for 2 d were allowed to refuel under three different ambient temperature conditions (-7 degrees, 7 degrees, and 22 degrees C). During the refueling period, as well as during the preceding control and starvation periods, food intake, body mass, and feces production were monitored. In addition, daily energy expenditure was measured during the refueling period. The compilation of the energy balance during the refueling period revealed an energy density of the deposited tissue of 33.6 kJ g-1. Assuming that the deposited tissue consists of fat and protein exclusively, with energy densities of 39.6 and 5.5 kJ g-1 wet mass, respectively, we estimated the deposited tissue to consist of 82% fat and 18% wet protein (6% dry protein and 12% water). Nitrogen balances during control, starvation, and refueling phases and during a period of prolonged and complete starvation indicated that 5% of the nutrient stores consisted of dry protein. Our results support recent findings that nutrient stores for migration often contain protein in addition to fat and consequently are 15%-25% less energy rich than pure fat stores. These proteins might be stored as muscle or other functional tissue and may be required to support the extra mass of the stores and/or reflect an incapacity of the metabolic machinery to catabolize far exclusively. Fuel deposition rate was positively related with ambient temperature, whereas food intake rate was unaffected by temperature. These results indicate that the rate of fuel deposition is limited by a ceiling in food intake rate; when this ceiling is reached, fuel deposition rate is negatively affected by daily energy expenditure rate. To a certain extent, the ceiling in food intake rate varies depending on feeding conditions over the previous days. These variations in food intake capacity probably reflect the building and breakdown of gut tissues and/or gut enzyme systems and might be insensible and not evolutionary adaptive. Significant energetic costs, however, are probably associated with the maintenance of gut tissues. It is therefore feasible that changes in digestive capacity are regulated and are directed at energy economization.

Barriers and enablers to safeguarding children and adults within a disability services context: Insights from an Australian Delphi Study

Research conducted in the 1990s revealed the tragic irony that exposure to the disability support system, and particularly to its institutional forms, was a major risk factor related to the neglect and abuse of children and adults with a disability. Subsequently, a range of policies have been introduced to minimize risk. However, recurring events of abuse and neglect in the disability services sector in high and middle income countries demonstrate that processes geared to safeguard children and adults with a disability from abuse and neglect remain insufficient. To establish the wider fabric of organizational factors that contribute to effective safeguarding practices within the Australian disability support sector, a modified online Delphi study was conducted, capturing the views of disability services staff and managers (n=249) regarding barriers and enablers to effective safeguarding. This study identified issues concerning organizational culture, management practice, workforce development, client capacity building and contextual factors. During Round Two of the Delphi, participants were asked to rate the categorized enabler statements according to importance on a 10-point Likert scale, to ascertain the degree of consensus. A total of 262 of the statements were regarded as important or very important. The Delphi result highlighted the considerable gap between the wider systemic and cultural processes that, in the eyes of disability services staff and management, contribute to good safeguarding practice and the safeguarding measures currently in place. The article calls for a holistic approach to safeguarding that addresses procedural issues and to the transformation of the wider systemic and cultural fabric of an organization.

Democracy, governance and political parties in India: an introduction

The party political domain of India is replete with a large number of parties representing the tapestry of Indian society. Many of them are based in specific regions and states, built around social and linguistic identities. While this enhanced the representative character of the parties, it also contributed to varied patterns of political competition and unstable governments. The two major national parties – the Congress and the Bharatiya Janata Party – becoming coalitionable heralded an era of coalition governments both at the Centre and states, enabling parties to increase their power and their pay-offs. Parties across the political spectrum have tended to converge on macro-economic policy, but continue to diverge on social policies and larger issues that confront India, such as nation building and secularism. Chronic lack of internal democracy coupled with the rise of political corruption and clientelist practices are matters of serious concern. A broader view of governance, resisting temptations to concentrate power and pursue personal enrichment, would enable parties to deliver policies for a better, more just society.

An abominable crime: filicide in the context of parental separation and divorce

The victims of filicide in the context of parental separation and divorce have recently been identified as the largest group among all filicide victims in Australia. Nevertheless, research into this group of victims has been sparse, fragmentary and contradictory, with the consequence that confusion has prevailed. This article critically reflects on the existing research on filicide and argues that it has been insufficiently comprehensive and reliable and, therefore, is not suitable for use as a knowledge base for professional individuals, programmatic and policy interventions, and prevention. The article suggests ways of developing more reliable research for knowledge building and details the data developed so far that underpins their recommendations for a national programme of research.

The Indian diaspora : Hindus and Sikhs in Australia

Since the late 1990s, the Indian community in Australia has grown faster than any other immigrant community. The Indian Diaspora has made substantial contributions to the multi-ethnic and multi-religious diversity within Australia. The growth of Hinduism and Sikhism through gurus, temples, yoga and rituals of many kind has brought new colours, images, customs and practices to the profile of Australian religion, and the Australian landscape more widely. At the same time, Hinduism and Sikhism have themselves been transformed as Hindus and Sikhs from different parts of India as well as Fiji, Malaysia and other parts of the world have come together to establish a pan-Indian ethos. Hindus and Sikhs here have also interacted with other sectors of the Australian population and with religions from the Western world. This is the theme of this book.The Indian Diaspora covers the theory of diaspora, the historical development of the Indian communities in Australia since the late 19th century to the present times, current practices and statistical profiles of Hindus and Sikhs in Australia, and interactions between Hindus and Sikhs with the wider Australian community. There are case-studies of the Indian students and women in the Australian community, of Indian communities in Melbourne and South Australia, and of temple building and the Sikh gurdwara. The book has been edited by and contains contributions from Purushottama Bilimoria, an internationally-known scholar of philosophy and religion, Jayant Bhalchandra Bapat, one of Australia’s most senior Hindu priests and a scholar of Hinduism, and Philip Hughes, a leading analyst of the religious profiles of the Australian people. It also contains contributions from several other prominent scholars. Included are special essays on the importance of diaspora by the late Ninian Smart and on the 19th century Afghan cameleers and Indian hawkers.
