Contrasting longitudinal and cross-sectional relationships between insulin resistance and percentage of body fat, fitness, and physical activity in children—the LOOK study

Background: Knowledge of individual changes in insulin resistance (IR) and longitudinal relationships of IR with lifestyle-associated factors are of important practical significance, but little longitudinal data exist in asymptomatic children. We aimed to determine (a) changes in the homeostatic model of insulin resistance (HOMA-IR) over a 2-yr period and (b) comparisons of longitudinal and cross-sectional relationships between HOMA-IR and lifestyle-related risk factors.

Methods: Our subjects, 241 boys and 257 girls, were assessed at age 8.1 yr (SD 0.35) and again 2 yr later for fasting blood glucose and insulin, dual X-ray absorptiometry-assessed percentage of body fat (%BF), pedometer-assessed physical activity (PA), and cardio-respiratory fitness (CRF) by multistage running test.

Results: HOMA-IR was initially 9% greater in girls than boys and 27% greater 2 yr later. There was no evidence of longitudinal relationships between HOMA-IR and %BF in boys or girls, despite significant cross-sectional relationships (p < 0.001). In boys, there was evidence of a longitudinal relationship between HOMA-IR and both PA (p < 0.001) and CRF (p = 0.05). In girls, we found a cross-sectional relationship between HOMA-IR and CRF (p < 0.001).

Conclusions: HOMA-IR increases between 8 and 10 yr of age and to a greater extent in girls. Longitudinal, unlike cross-sectional, relationships do not support the premise that body fat has any impact on HOMA-IR during this period or that PA or CRF changes affect HOMA-IR in girls. These data draw attention to difficulties in interpreting observational studies in young children.

Prediction of stress-strain behaviors in steels using an integrated constitutive, FEM and ANN model

Austenitic steels with a carbon content of 0.0037 to 0.79 wt% C are torsion tested and modeled using a physically based constitutive model and an Integrated Phenomenological and Artificial neural Network (IPANN) model. The prediction of both the constitutive and IPANN models on steel 0.017 wt% C is then evaluated using a finite element (FEM) code ABAQUS with different reduction in the thickness after rolling through one roll stand. It is found that during the rolling process, the prediction accuracy of the reaction force from FEM simulation for both constitutive and IPANN models depends on the strain achieved (average reduction in thickness). By integrating FEM into IPANN model and introducing the product of strain and stress as an input of the ANN model, the accuracy of this integrated FEM and IPANN model is higher than either the constitutive or IPANN model.

Herbert Spencer in the suburbs? Class, politics, ideology and the Australian petty-bourgeoisie in the Howard years

A dominant trope of media commentary after the 2004 federal election was the rise of blue-collar self-employment and small business and its negative impact on Labor electoral support. In this paper I examine the evidence on the growth of self-employment and small business in Australia since the 1980s and the political consequences of this growth. I consider why the growth of self-employment and small business has been overstated by many observers, and the emergence of a right-wing anti-capitalism in the critique of the dependence of wage-labour. Although the growth of self-employment and small business has been overstated it is a real phenomenon. I extract the rational kernel from the largely ill-informed commentary on this issue and place contemporary debates about self-employment in a historical and global context. I consider why the self-employed and small business were once seen as natural allies of the working-class in a populist coalition but why they are now identified by commentators as hostile to class politics.

A pHMM-ANN based discriminative approach to promoter identification in prokaryote genomic contexts

The computational approach for identifying promoters on increasingly large genomic sequences has led to many false positives. The biological significance of promoter identification lies in the ability to locate true promoters with and without prior sequence contextual knowledge. Prior approaches to promoter modelling have involved artificial neural networks (ANNs) or hidden Markov models (HMMs), each producing adequate results on small scale identification tasks, i.e. narrow upstream regions. In this work, we present an architecture to support prokaryote promoter identification on large scale genomic sequences, i.e. not limited to narrow upstream regions. The significant contribution involved the hybrid formed via aggregation of the profile HMM with the ANN, via Viterbi scoring optimizations. The benefit obtained using this architecture includes the modelling ability of the profile HMM with the ability of the ANN to associate elements composing the promoter. We present the high effectiveness of the hybrid approach in comparison to profile HMMs and ANNs when used separately. The contribution of Viterbi optimizations is also highlighted for supporting the hybrid architecture in which gains in sensitivity (+0.3), specificity (+0.65) and precision (+0.54) are achieved over existing approaches.

Smoking amongst UK Bangladeshi adolescents aged 14-15

This paper reports on an investigation into smoking amongst 14- to 15- year-old Bangladeshis living in an UK inner city locality. A survey using self-completion questionnaires was undertaken in conjunction with focus group discussions. The survey of 316 Bangladeshi adolescents was conducted to determine smoking prevalence. Regular smoking was more common amongst Bangladeshi males (39%) than amongst Bangladeshi females (11%). Thirty-one people (17 females and 14 males) took part in seven focus groups (four female and three male) which were conducted in schools (six) and youth clubs (one). Focus group discussions were conducted to examine what smoking means to Bangladeshi teenagers and factors which influence why they do or do not smoke. Differences between what smoking means to Bangladeshi females and males are identified which arise from perceived social norms and cultural values, and greatly influence smoking uptake. However, many of the reasons why Bangladeshi adolescents continue to smoke, stop smoking or never smoke appear similar to those identified in other studies with largely white adolescents. Factors underpinning adolescent choices together with the implications of the study findings for the development of smoking prevention initiatives for inner city Bangladeshi teenagers are discussed.

Book reviews : David Palmer, Ross Shanahan, and Martin Shanahan, eds., Australian Labor history reconsidered

An objective of this collection is to bring the history of the Australian labor movement to international attention. The editors introduce the collection with a brief overview of Australian labor history, emphasizing differences between the Australian and American experiences. The introduction argues that a unique aspect of Australian labor history is “laborism,” which is defined as the central place of the labor movement in Australian culture, as compared with the more marginal position of the labor movement in America. In Australia, this centrality is reflected in the embedding of trade unions and labor in the state through wage-fixing tribunals, a social security system designed to support the families of male wage earners, and the Australian Labor Party's strong links to the trade union movement. The introduction is informative and especially benefits from the insights of David Palmer, an American historian teaching at Adelaide's Flinders University. However, the introduction was apparently written later at the suggestion of an American reader and has thus not been fully integrated into the structure of the book.
