    Tactical and Logistical Compromise in the Management of Combat

    Get PDF
    In combat operations, sustainability as well as flexibility are paramount concern. Health maintenance and casualty management programs are crucial underpinnings of any such plans and must be thouroughly intrgrated with tactical operations. The structure and operation of medical services is essentially a function of command direction, and the decision for a specific form of supporting activity in any given maneuver is ultimately the responsibility of the operational commander

    Behind the scenes : the politics of planning Adelaide

    Get PDF
    Behind the Scenes examines planning in the City of Adelaide from 1972 until 1993 within the historical framework of City/State relations from 1836 when the Province of South Australia was founded. During this 21-year period, the City had its own planning and development control legislation separate from the rest of the State. Dr Llewellyn-Smith examines why this situation came about, why it continued for this particular period and why it ceased in 1993 when the separate legislation was repealed and the City became part of the State system under the new Development Act 1993. Behind the Scenes includes original interviews with many of the key individuals in the City and State who played influential roles during this period. Dr Llewellyn-Smith himself was the City Planner from 1974 until 1981 and then the Town Clerk/Chief Executive Officer of the Adelaide City Council from 1982 until 1993: this book, then, is both a work of scholarship and an insider’s account.

    Sport in the Lives of Young People with Intellectual Disabilities: Negotiating Disability, Identity and Belonging

    Get PDF
    Whilst there is now a growing body of sociological research on the role of sport in the social, gender and identity rehabilitation of people with physical impairments, research on the role of sport in the lives of people with intellectual disabilities primarily focuses on improving fitness, health and social interactions. Yet sport is not only a form of physical exercise, competition or leisure-it is also a powerful social institution within which social structures and power relations are reproduced and, less frequently, challenged. You don\u27t need an entire sports team or YourEllipticals meant for heavy performing athletes, you just need to be mentally into it. This paper provides insights into the role of sport and physical activity in the lives of four young Australians with intellectual disabilities or cognitive limitations from their own perspectives. Data from life history interviews elicits rich and in-depth insights, revealing that the meanings these young people give to their sporting experiences include-but also go beyond-concerns with fitness, health and social interactions. Though by no means representative of the role of sport for all young people with intellectual disabilities, it is evident that these four young people use sport to negotiate complex emotional worlds around disability, identity, and belonging-much like their physically impaired counterparts

    Food fussiness and food neophobia share a common etiology in early childhood

    Get PDF
    BACKGROUND: 'Food fussiness' (FF) is the tendency to be highly selective about which foods one is willing to eat, and emerges in early childhood; 'food neophobia' (FN) is a closely related characteristic but specifically refers to rejection of unfamiliar food. These behaviors are associated, but the extent to which their etiological architecture overlaps is unknown. The objective of this study was to quantify the relative contribution of genetic and environmental influences to variation in FF and FN in early childhood; and to establish the extent to which they share common genetic and environmental influences. METHOD: Participants were 1,921 families with 16-month-old twins from the Gemini birth cohort. Parents completed the Child Eating Behaviour Questionnaire which included three FF items and four FN items. Bivariate quantitative genetic modeling was used to quantify: (a) genetic and environmental contributions to variation in FF and FN; and (b) the extent to which genetic or environmental influences on FF and FN are shared across the traits. RESULTS: Food fussiness and FN were strongly correlated (r = .72, p < .001). Proportions of variation in FF were equally explained by genetic (.46; 95% CI: 0.41-0.52) and shared environmental influences (.46; 95% CI: 0.41-0.51). Shared environmental effects accounted for a significantly lower proportion of variation in FN (.22; 95% CI: 0.14-0.30), but genetic influences were not significantly different from those on FF (.58, 95% CI: 0.50-0.67). FF and FN largely shared a common etiology, indicated by high genetic (.73; 95% CI: 0.67-0.78) and shared environmental correlations (.78; 95% CI: 0.69-0.86) across the two traits. CONCLUSIONS: Food fussiness and FN both show considerable heritability at 16 months but shared environmental factors, for example the home environment, influenced more interindividual differences in the expression of FF than in FN. FF and FN largely share a common etiology

    Genetic and environmental influences on food preferences in adolescence

    Get PDF
    Background: Food preferences vary substantially among adults and children. Twin studies have established that genes and aspects of the shared family environment both play important roles in shaping children's food preferences. The transition from childhood to adulthood is characterized by large gains in independence, but the relative influences of genes and the environment on food preferences in late adolescence are unknown. Objective: The aim of this study was to quantify the contribution of genetic and environmental influences on food preferences in older adolescents. Design: Participants were 2865 twins aged 18-19 y from the TEDS (Twins Early Development Study), a large population-based cohort of British twins born during 1994-1996. Food preferences were measured by using a self-report questionnaire of 62 individual foods. Food items were categorized into 6 food groups (fruit, vegetables, meat or fish, dairy, starch foods, and snacks) by using factor analysis. Maximum likelihood structural equation modeling established genetic and environmental contributions to variations in preferences for each food group. Results: Genetic factors influenced a significant and substantial proportion of the variation in preference scores of all 6 food groups: vegetables (0.54; 95% CI: 0.47, 0.59), fruit (0.49; 95% CI: 0.43, 0.55), starchy foods (0.32; 95% CI: 0.24, 0.39), meat or fish (0.44; 95% CI: 0.38, 0.51), dairy (0.44; 95% CI: 0.37, 0.50), and snacks (0.43; 95% CI: 0.36, 0.49). Aspects of the environment that are not shared by 2 twins in a family explained all of the remaining variance in food preferences. Conclusions: Food preferences had a moderate genetic basis in late adolescence, in keeping with findings in children. However, by this older age, the influence of the shared family environment had disappeared, and only aspects of the environment unique to each individual twin influenced food preferences. This finding suggests that shared environmental experiences that influence food preferences in childhood may not have effects that persist into adulthood

    Behavioural susceptibility theory: the role of appetite in genetic susceptibility to obesity in early life

    Get PDF
    Excess weight gained during the early years and, in particular, rapid weight gain in the first 2 years of life, are a major risk factors for adult obesity. The growing consensus is that childhood obesity develops from a complex interaction between genetic susceptibility and exposure to an 'obesogenic' environment. Behavioural susceptibility theory (BST) was developed to explain the nature of this gene-environment interaction, and why the 'obesogenic' environment does not affect all children equally. It hypothesizes that inherited variation in appetite, which is present from birth, determines why some infants and children overeat, and others do not, in response to environmental opportunity. That is, those who inherit genetic variants promoting an avid appetite are vulnerable to overeating and developing obesity, while those who are genetically predisposed to have a smaller appetite and lower interest in food are protected from obesity-or even at risk of being underweight. We review the breadth of research to-date that has contributed to the evidence base for BST, focusing on early life, and discuss implications and future directions for research and theory. This article is part of a discussion meeting issue 'Causes of obesity: theories, conjectures and evidence (Part I)'

    Tree Unitarity and Partial Wave Expansion in Noncommutative Quantum Field Theory

    Get PDF
    The validity of the tree-unitarity criterion for scattering amplitudes on the noncommutative space-time is considered, as a condition that can be used to shed light on the problem of unitarity violation in noncommutative quantum field theories when time is noncommutative. The unitarity constraints on the partial wave amplitudes in the noncommutative space-time are also derived.Comment: 15 pages, 1 figur

    The Role of Eating Behaviours in Genetic Susceptibility to Obesity

    Get PDF
    Purpose of Review Eating behaviours are hypothesised to be the behavioural expression of genetic risk of obesity. In this review, we summarise findings from behavioural genetic research on the association between genetic risk for obesity and validated psychometrics measures of eating behaviours in children and adults (published in the past 10 years). Recent Findings Twin studies have produced some evidence for a shared genetic aetiology underlying body mass index and eating behaviours. Studies using measured genetic susceptibility to obesity have suggested that increased genetic liability for obesity is associated with variation in obesogenic eating behaviours such as emotional and uncontrolled eating. Summary More research on this topic is needed. Especially longitudinal studies using genetically sensitive designs to investigate the direction of genetic pathways between genetic liability of eating behaviours to weight and vice versa, as well as the potential subsequent link to eating disorders
